Dispersion serial dilution methods using the gradient diluter device.  

PubMed

A solute aspirated into a prefilled tube of diluent undergoes a dilution effect known as dispersion. Traditionally the effects of dispersion have been considered a negative consequence of using liquid-filled fixed-tip liquid handlers. We present a novel device and technique that utilizes the effects of dispersion to the benefit of making dilutions. The device known as the Gradient Diluter extends the dilution range of practical serial dilutions to six orders of magnitude in final volumes as low as 10??L. Presented are the device, dispersion methods, and validation tests using fluorescence detection of sulforhodamine and the high-performance liquid chromatography/ultraviolet detection of furosemide. In addition, a T-cell inhibition assay of a relevant downstream protein is used to demonstrate IC(50) curves made with the Gradient Diluter compare favorably with those generated by hand.

Bayesian analysis of serial dilution assays.  

PubMed

In a serial dilution assay, the concentration of a compound is estimated by combining measurements of several different dilutions of an unknown sample. The relation between concentration and measurement is nonlinear and heteroscedastic, and so it is not appropriate to weight these measurements equally. In the standard existing approach for analysis of these data, a large proportion of the measurements are discarded as being above or below detection limits. We present a Bayesian method for jointly estimating the calibration curve and the unknown concentrations using all the data. Compared to the existing method, our estimates have much lower standard errors and give estimates even when all the measurements are outside the "detection limits." We evaluate our method empirically using laboratory data on cockroach allergens measured in house dust samples. Our estimates are much more accurate than those obtained using the usual approach. In addition, we develop a method for determining the "effective weight" attached to each measurement, based on a local linearization of the estimated model. The effective weight can give insight into the information conveyed by each data point and suggests potential improvements in design of serial dilution experiments. PMID:15180666

Establishing quality assurance criteria for serial dilution operations on liquid-handling equipment.  

PubMed

Since the advent of high-throughput screening (HTS) in the early 1990s, parallel multichannel liquid handlers have become a mainstay in every drug discovery setting. Although several peer-reviewed publications have discussed methods and criteria for stamping multiwell copies, there is very little information about establishing a standard operating procedure (SOP) for standard (microliter-level) serial dilutions of compounds used in dose-response experiments. The authors discuss the 4 main criteria any serial dilution process must pass (accuracy, precision, fold dilution, and outliers) and the process for establishing thresholds for all of these values in a compound management or biological screening laboratory. The thresholds need to be both low enough to be acceptable from a biological potency variability perspective and high enough to allow the instruments to pass the quality assurance (QA) analysis on a regular basis. In this article, the authors suggest suitable thresholds arrived at by a variety of methods, including trend analysis of QA data, survey questionnaire from the main stakeholders (screening scientists, chemists), and published criteria for single-shot stamping. A mathematical analysis of the effect of threshold values on estimated XC(50)s was performed to ensure that the variability introduced by the serial dilution step is within acceptable overall variability limits.

Exploration of the key microbes involved in the cellulolytic activity of a microbial consortium by serial dilution.  

PubMed

A highly cellulolytic consortium was serially diluted and incubated in fermentation medium with filter paper as carbon sources. The critical dilution point of the consortium for effective degradation of filter paper was 10(-5) as further dilution resulted in the loss of degradation ability of filter paper accompanied by the disappearance of four bands in denaturing gradient gel electrophoresis profiles. The loss of bands corresponding to 16S rRNA sequences from Clostridium clariflavum DSM 19732 and a Paenibacillus species coincided with the loss of degradation ability of filter paper. PMID:23265814

Transmission Probabilities of Mouse Parvovirus 1 to Sentinel Mice Chronically Exposed to Serial Dilutions of Contaminated Bedding  

PubMed Central

Intermittent serodetection of mouse parvovirus (MPV) infections in animal facilities occurs frequently when soiled bedding sentinel mouse monitoring systems are used. We evaluated induction of seroconversion in naïve single-caged weanling ICR mice (n = 10 per group) maintained on 5-fold serially diluted contaminated bedding obtained from SCID mice persistently shedding MPV1e. Soiled bedding from the infected SCID mice was collected, diluted, and redistributed weekly to cages housing ICR mice to represent chronic exposure to MPV at varying prevalence in a research colony. Sera was collected every other week for 12 wk and evaluated for reactivity to MPV nonstructural and capsid antigens by multiplex fluorescent immunoassay. Mice were euthanized after seroconversion, and DNA extracted from lymph node and spleen was evaluated by quantitative PCR. Cumulative incidence of MPV infection for each of the 7 soiled bedding dilution groups (range, 1:5 to 1:78125 [v/v]) was 100%, 100%, 90%, 20%, 70%, 60%, and 20%, respectively. Most seropositive mice (78%) converted within the first 2 to 3 wk of soiled bedding exposure, correlating to viral exposure when mice were 4 to 7 wk of age. Viral DNA was detected in lymphoid tissues collected from all mice that were seropositive to VP2 capsid antigen, whereas viral DNA was not detected in lymphoid tissue of seronegative mice. These data indicate seroconversion occurs consistently in young mice exposed to high doses of virus equivalent to fecal MPV loads observed in acutely infected mice, whereas seroconversion is inconsistent in mice chronically exposed to lower doses of virus.

EMJH medium with 5-fluorouracil and nalidixic acid associated with serial dilution technique used to recover Leptospira spp from experimentally contaminated bovine semen  

PubMed Central

Bovine semen experimentally contaminated with Leptospira santarosai serovar Guaricura was submitted to the modified EMJH medium with 5-fluorouracil (300mg/L) and nalidixic acid (20mg/L), named as “selective medium” and using the serial dilution technique, in order to evaluate the percentage of recovery of the added microorganism. The selective EMJH medium was found with higher percentage of recovery of leptospiras and minor losses of samples due to contamination with opportunistic microorganisms than the non-selective EMJH medium: 151/376 (40.0%) of positive growth; and 38/376 (10.0%) contamination and 58/376 (15%) and 129/376 (34.0%), respectively. These results were statistically significant (p<0. 0001; Fisher). Differences were found when the frequencies of positive leptospires recovery have been compared in the serial dilution technique (10-1 to 10-4) between the selective and non-selective media at different dilution factors. At 1/10th dilution the percentages found were (0%, 0/80) and (38%, 30/80), at 1/100th dilution, (3%, 2/80) and (49%, 39/ 80) and at 1/1,000th dilution, (25%, 20/80) and (50%, 40/80), respectively. The percentage of recovery of leptospires was found to be directly proportional to the dilution used. The methodology of the serial dilution technique (setting at least three dilutions) and the use of selective EMJH medium have been found to be efficient for the isolation of leptospires from the bovine semen samples.

Differences in Median Ultraviolet Light Transmissions of Serial Homeopathic Dilutions of Copper Sulfate, Hypericum perforatum, and Sulfur.  

PubMed

Homeopathic remedies are produced by potentising, that is, the serial logarithmic dilution and succussion of a mother tincture. Techniques like ultraviolet spectroscopy, nuclear magnetic resonance, calorimetry, or thermoluminescence have been used to investigate their physical properties. In this study, homeopathic centesimal (c) potencies (6c to 30c) of copper sulfate, Hypericum perforatum, and sulfur as well as succussed water controls were prepared. Samples of these preparations were exposed to external physical factors like heat, pressure, ultraviolet radiation, or electromagnetic fields to mimic possible everyday storage conditions. The median transmissions from 190?nm to 340?nm and 220?nm to 340?nm were determined by ultraviolet light spectroscopy on five measurement days distributed over several months. Transmissions of controls and potencies of sulfur differed significantly on two of five measurement days and after exposure to physical factors. Transmissions of potencies exposed to ultraviolet light and unexposed potencies of copper sulfate and Hypericum perforatum differed significantly. Potency levels 6c to 30c were also compared, and wavelike patterns of higher and lower transmissions were found. The Kruskal-Wallis test yielded significant differences for the potency levels of all three substances. Aiming at understanding the physical properties of homeopathic preparations, this study confirmed and expanded the findings of previous studies. PMID:23401712

Sex Is Always Well Worth Its Two-Fold Cost  

PubMed Central

Sex is considered as an evolutionary paradox, since its positive contribution to Darwinian fitness remains unverified for some species. Defenses against unpredictable threats (parasites, fluctuating environment and deleterious mutations) are indeed significantly improved by wider genetic variability and by positive epistasis gained by sexual reproduction. The corresponding evolutionary advantages, however, do not overcome universally the barrier of the two-fold cost for sharing half of one's offspring genome with another member of the population. Here we show that sexual reproduction emerges and is maintained even when its Darwinian fitness is twice as low as the fitness of asexuals. We also show that more than two sexes (inheritance of genetic material from three or even more parents) are always evolutionary unstable. Our approach generalizes the evolutionary game theory to analyze species whose members are able to sense the sexual state of their conspecifics and to adapt their own sex consequently, either by switching or by taxis towards the highest concentration of the complementary sex. The widespread emergence and maintenance of sex follows therefore from its co-evolution with the even more widespread environmental sensing abilities.

The two-fold singularity of nonsmooth flows: Leading order dynamics in n-dimensions  

NASA Astrophysics Data System (ADS)

A discontinuity in a system of ordinary differential equations can create a flow that slides along the discontinuity locus. Prior to sliding, the flow may have collapsed onto the discontinuity, making the reverse flow non-unique, as happens when dry-friction causes objects to stick. Alternatively, a flow may slide along the discontinuity before escaping it at some indeterminable time, implying non-uniqueness in forward time. At a two-fold singularity these two behaviours are brought together, so that a single point may have multiple possible futures as well as histories. Two-folds are a generic consequence of discontinuities in three or more dimensions, and play an important role in both local and global dynamics. Despite this, until now nothing was known about two-fold singularities in systems of more than 3 dimensions. Here, the normal form of the two-fold is extended to higher dimensions, where we show that much of its lower dimensional dynamics survives.

Two-fold Mellin-Barnes transforms of Usyukina-Davydychev functions  

NASA Astrophysics Data System (ADS)

In our previous paper (Allendes et al., 2013 [10]), we showed that multi-fold Mellin-Barnes (MB) transforms of Usyukina-Davydychev (UD) functions may be reduced to two-fold MB transforms. The MB transforms were written there as polynomials of logarithms of ratios of squares of the external momenta with certain coefficients. We also showed that these coefficients have a combinatoric origin. In this paper, we present an explicit formula for these coefficients. The procedure of recovering the coefficients is based on taking the double-uniform limit in certain series of smooth functions of two variables which is constructed according to a pre-determined iterative way. The result is obtained by using basic methods of mathematical analysis. We observe that the finiteness of the limit of this iterative chain of smooth functions should reflect itself in other mathematical constructions, too, since it is not related in any way to the explicit form of the MB transforms. This finite double-uniform limit is represented in terms of a differential operator with respect to an auxiliary parameter which acts on the integrand of a certain two-fold MB integral. To demonstrate that our result is compatible with original representations of UD functions, we reproduce the integrands of these original integral representations by applying this differential operator to the integrand of the simple integral representation of the scalar triangle four-dimensional integral J(1,1,1-?).

Gain-assisted giant Kerr nonlinearity in a {?}-type system with two-folded lower levels  

NASA Astrophysics Data System (ADS)

We propose a four-level ? scheme with a one-mode active Raman gain core and two-folded lower levels to obtain new linear and nonlinear optical responses. We show that this scheme is fundamentally different from that based on electromagnetically induced transparency (EIT). Firstly, it is gain-assisted and thus capable of eliminating all attenuation of probe field. Furthermore, due to the quantum interference effect introduced by a coupling field a gain doublet appears in gain spectrum, and hence the distortion of the probe field during propagation can be effectively avoided. In addition, in such system a large and rapidly responding Kerr nonlinearity can be produced, which is much (more than 10 times) larger than that obtained in the EIT-based scheme with the same energy-level configuration.

Composition during serial learning: a serial position effect.  

PubMed

Composition is a computational learning mechanism that merges serially performed elementary processes into hierarchically organized knowledge structures. The main goals of this research were to explore (a) the role of serial position in composition and (b) the relation between degree of composition and explicit serial recall in serial learning. In 3 experiments, Ss performed a rule-based serial reaction time task in which they had to categorize a sequence of 12 stimuli shown simultaneously on a video monitor. A procedure based on the comparison of reaction times to random sequences and a repeating sequence identified a serial position effect of composition that was, however, moderated by Ss' explicit, postexperimental recall of the repeating sequence. A production-system-based computational model of composition is described that qualitatively reproduces the empirical findings. Implications for the mechanisms governing serial learning are discussed. PMID:8151278

Serial Code Optimization  

NSDL National Science Digital Library

This guide presents the main features of serial optimisation for computationally intensive codes with a focus on the HECToR computing resources. From a user point of view, two main avenues can be followed when trying to optimise an application. One type of optimisations DO NOT involve modifying the source code (modification may not be desirable); optimisation consists of searching for the best compiler, set of flags and libraries. Another type of optimisations DO involve modifying the source code; in the first instance the programmer must evaluate if a new algorithm is necessary, followed by writing or rewriting optimised code. According to the these choices this guide presents optimisation as a problem of compiler and library selection, followed by a presentation of the key factors that must be considered when writing numerically intensive code.

Serial replica exchange.  

PubMed

Parallel tempering (or the replica exchange method (REM)) is a powerful method for speeding up the sampling of conformational states of systems with rough energy landscapes, like proteins, where stable conformational states can be separated by large energy barriers. The usual implementation of the REM is performed on local computer clusters (or parallel processors) where the different replicas must be run synchronously. Here, we present serial replica exchange (SREM), a method that is equivalent to the standard REM in terms of efficiency yet runs asynchronously on a distributed network of computers. A second advantage is the method's greatly enhanced fault tolerance, which enables the study of biological systems on worldwide distributed computing environments, such as Folding@Home. For proof of concept, we apply the SREM to a single alanine dipeptide molecule in explicit water. We show that the SREM reproduces the thermodynamic and structural properties determined by the REM.

Union lists of serials share many elements in common with catalogs of serials, and so are similarly affected by serials cataloging practices. However, since a union list is a consolidation of serials data from a number of libraries, more cataloging discrepancies will require resolving in it than in any one library's catalog. In this article, various serials cataloging issues are

A modified Ubbelohde viscometer with improved dilution characteristics  

NASA Astrophysics Data System (ADS)

A simple modification of the standard Ubbelohde dilution viscometer is proposed. This modification consists of replacing the commercially supplied dilution reservoir with a siphon tube leading to a much larger custom built storage container. Typically, the usual two fold dilution capability of commercial pieces can be increased to as much as ten or twelve fold without loss of accuracy. Examples are presented which illustrate how this simplifies and accelerates data acquisition for the routine measurement of polymer intrinsic viscosity, and in addition, allows for the measurement of such, using very small quantities of polymer. The former is illustrated through routine measurement of the intrinsic viscosity of a thermoplastic polyelectrolyte polymer containing 2-hydroxyethyl methacrylate and methacrylic acid; and the latter through an analysis of changes in intrinsic viscosity accompanying thermally induced chain scission in Phenoxy resin (Union Carbide, poly bisphenol A, 2-hydroxypropylether).

Serial Input Output  

SciTech Connect

Serial Input/Output (SIO) is designed to be a long term storage format of a sophistication somewhere between simple ASCII files and the techniques provided by inter alia Objectivity and Root. The former tend to be low density, information lossy (floating point numbers lose precision) and inflexible. The latter require abstract descriptions of the data with all that that implies in terms of extra complexity. The basic building blocks of SIO are streams, records and blocks. Streams provide the connections between the program and files. The user can define an arbitrary list of streams as required. A given stream must be opened for either reading or writing. SIO does not support read/write streams. If a stream is closed during the execution of a program, it can be reopened in either read or write mode to the same or a different file. Records represent a coherent grouping of data. Records consist of a collection of blocks (see next paragraph). The user can define a variety of records (headers, events, error logs, etc.) and request that any of them be written to any stream. When SIO reads a file, it first decodes the record name and if that record has been defined and unpacking has been requested for it, SIO proceeds to unpack the blocks. Blocks are user provided objects which do the real work of reading/writing the data. The user is responsible for writing the code for these blocks and for identifying these blocks to SIO at run time. To write a collection of blocks, the user must first connect them to a record. The record can then be written to a stream as described above. Note that the same block can be connected to many different records. When SIO reads a record, it scans through the blocks written and calls the corresponding block object (if it has been defined) to decode it. Undefined blocks are skipped. Each of these categories (streams, records and blocks) have some characteristics in common. Every stream, record and block has a name with the condition that each stream, record or block name must be unique in its category (i.e. all streams must have different names, but a stream can have the same name as a record). Each category is an arbitrary length list which is handled by a 'manager' and there is one manager for each category.

950 keV X-Band Linac For Material Recognition Using Two-Fold Scintillator Detector As A Concept Of Dual-Energy X-Ray System  

SciTech Connect

One of the advantages of applying X-band linear accelerator (Linac) is the compact size of the whole system. That shows us the possibility of on-site system such as the custom inspection system in an airport. As X-ray source, we have developed X-band Linac and achieved maximum X-ray energy 950 keV using the low power magnetron (250 kW) in 2 {mu}s pulse length. The whole size of the Linac system is 1x1x1 m{sup 3}. That is realized by introducing X-band system. In addition, we have designed two-fold scintillator detector in dual energy X-ray concept. Monte carlo N-particle transport (MCNP) code was used to make up sensor part of the design with two scintillators, CsI and CdWO4. The custom inspection system is composed of two equipments: 950 keV X-band Linac and two-fold scintillator and they are operated simulating real situation such as baggage check in an airport. We will show you the results of experiment which was performed with metal samples: iron and lead as targets in several conditions.

Evaluation of performance across the dynamic range of the Abbott RealTime HIV-1 assay as compared to VERSANT HIV-1 RNA 3.0 and AMPLICOR HIV-1 MONITOR v1.5 using serial dilutions of 39 group M and O viruses.  

PubMed

Performance of the Abbott m2000 instrument system and the Abbott RealTime HIV-1 assay was evaluated using a panel of 37 group M (subtypes A-D, F, G, CRF01_AE, CRF02_AG and unique recombinant forms) and 2 group O virus isolates. Testing was performed on 273 sample dilutions and compared to VERSANT HIV-1 RNA 3.0 (bDNA) and AMPLICOR HIV-1 MONITOR v1.5 (Monitor v1.5) test results. RealTime HIV-1, bDNA, and Monitor v1.5 tests quantified 87%, 78%, and 81% of samples, respectively. RealTime HIV-1 detected an additional 31 samples at < 40 copies/mL. For group M, RealTime HIV-1 dilution profiles and viral loads were highly correlated with bDNA and Monitor v1.5 values; 87% and 89% of values were within 0.5 log(10) copies/mL. In contrast, the group O viruses were not detected by Monitor v1.5 and were substantially underquantified by approximately 2 log(10) copies/mL in bDNA relative to the RealTime HIV-1 assay. Sequence analysis revealed that RealTime HIV-1 primer/probe binding sites are highly conserved and exhibit fewer nucleotide mismatches relative to Monitor v1.5. The automated m2000 system and RealTime HIV-1 assay offer the advantages of efficient sample processing and throughput with reduced "hands-on" time while providing improved sensitivity, expanded dynamic range and reliable quantification of genetically diverse HIV-1 strains.

Serial homicide has attracted much attention, but little empirical scientific investigation. This exploratory study reports demographic information on a large sample of serial homicide offenders (157 offenders, 608 victims), and compares a subsample of serial homicide offenses with a control group of single homicide offenses. Results show that serial homicide offenders target more women than men, and kill more strangers than family or friends. Single homicide offenders kill men and women in equal frequency, but kill family and friends more often than strangers. Serial homicide offenders kill for apparent sexual motivation more often than for any other reason, while single homicide offenders kill most often out of anger. PMID:15211555

Expression profiling of non-aflatoxigenic Aspergillus parasiticus mutants obtained by 5-azacytosine treatment or serial mycelial transfer.  

PubMed

Aflatoxins are carcinogenic secondary metabolites produced by the fungi Aspergillus flavus and Aspergillus parasiticus. Previous studies found that repeated serial mycelial transfer or treatment of A. parasiticus with 5-azacytidine produced colonies with a fluffy phenotype and inability to produce aflatoxins. To understand how these treatments affect expression of genes involved in aflatoxin production and development, we carried out expressed sequence tag (EST)-based microarray assays to identify genes in treated clones that are differentially expressed compared to the wild-type. Expression of 183 genes was significantly dysregulated. Of these, 38 had at least two-fold or lower expression compared to the untreated control and only two had two-fold or higher expression. The most frequent change was downregulation of genes predicted to encode membrane-bound proteins. Based on this result we hypothesize that the treatments cause changes in the structure of cellular and organelle membranes that prevent normal development and aflatoxin biosynthesis. PMID:22069749

Dilution assay statistics.  

PubMed Central

A parametric method of statistical analysis for dilution assays is developed in detail from first principles of probability and statistics. The method is based on a simple product binomial model for the experiment and produces an estimate for the concentration of target entities, a confidence interval for this concentration, and an indicator of the quality of the assay called the p value for goodness of fit. The procedure is illustrated with data from a virologic quantitative micrococulture assay used to quantify free human immunodeficiency virus in clinical trials. The merits of the procedure versus those of nonparametric methods of estimating the dilution inducing a 50% response rate are discussed. Advantages of the proposed approach include plausibility of the underlying assumptions, ability to assess plausibility of specific experimental outcomes through their likelihood, and plausibility of confidence intervals.

Electrically pumped random lasing from the light-emitting device based on two-fold-tandem SiO2/ZnO structure  

NASA Astrophysics Data System (ADS)

We report on remarkable decrease in threshold current for electrically pumped random lasing (RL) from the light-emitting device based on two-fold-tandem (double-) SiO2/ZnO-structure with respect to that in the case of single-SiO2/ZnO-structured device. Moreover, the former is of higher power conversion efficiency. In the double-SiO2/ZnO-structure, a waveguide is formed by the stacking SiO2/ZnO/SiO2, which enables photon confinement. Moreover, the electrons leaking out of the bottom SiO2/ZnO-structure are collected and partly involved in the radiative recombination in the top one. Furthermore, the RL photons generated in the bottom SiO2/ZnO-structure act as the stimuli to increase the stimulated emission rate in the top one. For the above-mentioned reasons, the RL performance of the double-SiO2/ZnO-structured device is substantially improved.

Real and imaginary parts of the impedance are obtained by applying a parametric identification method (extended Prony), but other techniques are easily adaptable. Image reconstruction is carried out using the Sheffield filtered back-projection algorithm. Characteristic frequency images are under development and should be of great interest to distinguish between normal and tumorous tissues. PMID:9001597

Serials standards work: the next frontier.

Serials, one of the more complicated areas of library technical endeavors, has lacked the benefit of standards for a long time. Even now, with standards beginning to be available, the majority of institutions are not working within standard serials formats. A survey to determine the use of serials standards in libraries was conducted in 1988 by the American Library Association, Resources and Technical Services Division, Serials Section, Committee to Study Serials Standards. In the spring of 1988 a survey was sent to a group encompassing the Association of Research Libraries members, CONSER participants, United States Newspaper Program participants, Microform Project libraries, and some vendors and librarians who attended the Committee meetings on a regular basis. The survey questionnaire assessed the current level of serials standards awareness of librarians and vendors. Topics included the type of serials systems used, standards relevant to serials control and union listing and whether or not they are implemented, types and levels of training staff received in the application of standards, benefits of the standards, and areas where standards are most needed.

Dilution apparatus and method  

SciTech Connect

This patent describes a process for the secondary and tertiary recovery of oil from an oil-bearing subterranean formation having at least one input well and at least one output well which process includes the preparation of an aqueous solution of a polymer consisting essentially of a partially hydrolyzed polyacrylamide capable of meeting the performance demands of an oil-bearing subterranean formation. The polymer solution is introduced. The step of diluting the aqueous polymer solution has a polymer concentration such that the solution has a gel-like consistency to provide an aqueous polymer solution, with a substantially non-gel-like consistency while at the same time minimizing polymer degradation as the aqueous polymer solution is undergoing a physical change from a gel-like consistency to a substantially non gel-like consistency. This enables the partially hydrolyzed polyacrylamide to to retain its capability for meeting the performance demands of an oil-bearing formation into which an aqueous solution containing the polymer is introduced. The dilution is carried out by continuously dispersing an aqueous solution of the polymer of known concentration having a gel-like consistency into a chamber, having an inlet and an outlet, by passing the polymer solution through distributor means at the inlet of the chamber to increase the surface area of the gel-like polymer solution.

Structural Variations in ?-(BDA-TTP)2FeCl4 at Low Temperature and under Pressure: Charge-Ordered State with a Two-Fold Crystal Structure  

NASA Astrophysics Data System (ADS)

The pressure-induced organic superconductor ?-(BDA-TTP)2FeCl4 [BDA-TTP = 2,5-bis(1,3-dithian-2-ylidene)-1,3,4,6-tetrathiapentalene], which shows a metal--insulator (MI) transition at TMI = 113 K under ambient pressure, has been found by X-ray study to have a two-fold crystal structure along the c-axis in the insulating state at 10 K. In the donor layer, there are four independent BDA-TTP molecules, which are divided into two charge-poor ones and two charge-rich ones on the basis of the folding dihedral angles around the intramolecular sulfur-to-sulfur axes of two outer dithiane rings in BDA-TTP. The charge separation leads to the formation of two types of dimers: a dimer consisting of two charge-poor donors and a dimer consisting of two charge-rich ones. The tight-binding band calculation revealed a band gap of 5.3 meV in the energy dispersion. The MI transition can be therefore accounted for by the charge separation. In addition, we investigated the crystal and electronic structures of ?-(BDA-TTP)2FeCl4 at different pressures up to 21 kbar, and found that the application of pressures causes variations in both the conformation of donor molecule and the donor arrangement, which are responsible for almost uniform interaction in the donor stacking and for an increase in bandwidth (W). As a result, the suppression of MI transition and subsequent occurrence of superconductivity in ?-(BDA-TTP)2FeCl4 would be observed with increasing pressure.

3D coordination framework with uncommon two-fold interpenetrated {3(3)5(9)6(3)}-lcy net and coordinated anion exchange.  

PubMed

Unusual {3(3)5(9)6(3)}-lcy topology has been found in an uncommon 3D six-connected, two-fold interpenetrated {3(3)5(9)6(3)}-lcy net (illustrated). The coordinated SO(4) (2-) anions in this framework can undergo a full exchange with Cl(-) anions, in the course of which the crystals change color as shown. The process has a solvent-mediated rather than a solid-state mechanism.Reaction of tetrazole-1-acetic acid with CuSO(4)5H(2)O produces two novel 3D coordination frameworks: ([Cu(3)(mu(3)-OH)(eta(1):eta(1):eta(1):mu(3)-SO(4))(tza)(3)]3 CH(3)OHH(2)O}(n) (1; Htza=tetrazole-1-acetic acid) and {[Cu(4)(mu(2)-OH)(eta(2):eta(2):mu(4)-SO(4))(tta)(5)]3 H(2)O}(n) (2; Htta=tetrazole). Framework 1 is constructed from a trinuclear copper cluster [Cu(3)(mu(3)-OH)(eta(1):eta(1):eta(1):mu(3)-SO(4))] and displays a six-connected framework with uncommon {3(3)5(9)6(3)}-lcy topology. Framework 2 presents a complicated five-nodal (3,4,6)-connected net with (4(2)6)(34(2)5(2)7)(4(3)6(2)8)(3(2)4(8)5(3)6(2))(4(6)8(6)10(3)) topology. The eta(2):eta(2):mu(4)-SO(4) bridging mode in 2 has not been found in the reported coordination polymers. The coordinated SO(4) (2-) anions in 1 can be replaced completely when the solid polymer is treated with an aqueous methanolic solution containing Cl(-) anions. Detailed atomic force microscopy studies indicate a solvent-mediated rather than a solid-state mechanism for the exchange process. PMID:19263444

Criminal psychological profiling of serial arson crimes.  

PubMed

The practice of criminal psychological profiling is frequently cited as being applicable to serial arson crimes. Despite this claim, there does not appear to be any empirical research that examines serial arson offence behaviors in the context of profiling. This study seeks to develop an empirical model of serial arsonist behaviors that can be systematically associated with probable offender characteristics. Analysis has produced a model of offence behaviors that identify four discrete behavior patterns, all of which share a constellation of common nondiscriminatory behaviors. The inherent behavioral themes of each of these patterns are explored with discussion of their broader implications for our understanding of serial arson and directions for future research.

Dilute Suspensions near Walls  

NASA Astrophysics Data System (ADS)

A precise account of particle-wall hydrodynamic interactions is important for modelling the motion of dilute suspensions near walls. Particles considered here are solid, spherical and small enough for the Reynolds number of the flow around each particle to be small compared with unity. At first order in Reynolds number, Stokes equations apply. Ambient flow fields are expressed as polynomials in terms of the coordinates. Various flow fields perturbed by a spherical particle near a wall may be superimposed by linearity of Stokes equations. Their solutions are recalled; they were calculated with the bispherical coordinates technique, providing precise results for the drag and torque on a particle. For particles in a gas, particle inertia may be important even though for low Reynolds number fluid inertia is negligible. It is shown that collision of a particle on a wall is not possible in creeping flow even if particle inertia is not negligible. At second order in the low Reynolds number, a small fluid inertia appears. For a sphere moving in a linear shear flow and a quadratic shear flow along a wall, there is then a lift force. The various pair couplings between sphere translation, rotation and the shear flows provide contributions to the lift. For a particle moving normal to a wall in a quiescent fluid at constant velocity, fluid inertia provides steady and unsteady contributions to the drag force.

Serial order in spatial immediate memory.  

PubMed

Serial order effects in spatial memory are investigated in three experiments. In the first an analysis of errors in recall data suggested that immediate transpositions were the most common error and that order errors over 2 or 3 adjacent items accounted for the majority of errors in recall. The first and last serial positions are less error-prone than is the middle position in sets of six and seven items. A second experiment investigated recognition of transpositions and found that immediate transpositions were hardest to recognize but that a traditional serial position effect was not found. This may be due to the difficulty of maintaining one set of spatial items when another set is presented for comparison. A probe experiment, in which subjects were asked to recognize whether a single item came from a memory set and then to assign it to its position in the set indicated that the first and last positions were remembered more accurately than were central positions. The combination of serial order data in recall and position data suggests that there are similarities between serial order and position effects in the verbal and spatial domains and that serial order in spatial sequences is position-based.

Serial concept maps: tools for concept analysis.  

PubMed

Nursing theory challenges students to think abstractly and is often a difficult introduction to graduate study. Traditionally, concept analysis is useful in facilitating this abstract thinking. Concept maps are a way to visualize an individual's knowledge about a specific topic. Serial concept maps express the sequential evolution of a student's perceptions of a selected concept. Maps reveal individual differences in learning and perceptions, as well as progress in understanding the concept. Relationships are assessed and suggestions are made during serial mapping, which actively engages the students and faculty in dialogue that leads to increased understanding of the link between nursing theory and practice. Serial concept mapping lends itself well to both online and traditional classroom environments. PMID:17547345

Compact disc serial number inspection system  

NASA Astrophysics Data System (ADS)

This paper presents a reliable neural network based system for compact disc serial number inspection. Four major steps are performed in this system, namely polar image conversion, segmentation, recognition, and verification. Polar image conversion straightens the circular stripe images containing the serial numbers to horizontally linear images, segmentation divides the images into separate character segments, recognition classifies the separate character segments by a trained neural network, and verification double checks the characters with their verification neural networks if the serial number is known. Special back-propagation training processes for recognition and verification neural networks are used to increase the system's performance. Excellent recognition results for this system implemented in the Sony SUPER vision system have been obtained. Moreover, this system can process more than 3 compact discs in one second.

Serial position effects in mild cognitive impairment

Mild cognitive impairment (MCI) is often associated with the preclinical phase of Alzheimer's disease (AD). Special scoring of word-list recall data for serial position has been suggested to improve discrimination of normal aging from dementia. We examined serial position effects in word-list recall for MCI participants compared to Alzheimer patients and controls. Individuals with MCI, like Alzheimer patients, had a diminished primacy effect in recalling words from a list. No alternative scoring system was better than standard scoring of word list recall in distinguishing MCI patients from controls. Retention weighted scoring improved the discrimination of MCI and AD groups.

Dilution and the elusive baseline.  

PubMed

Knowledge of baseline conditions is critical for evaluating quantitatively the effect of human activities on environmental conditions, such as the impact of acid deposition. Efforts to restore ecosystems to prior, "pristine" condition require restoration targets, often based on some presumed or unknown baseline condition. Here, we show that rapid and relentless dilution of surface water chemistry is occurring in the White Mountains of New Hampshire, following decades of acid deposition. Extrapolating measured linear trends using a unique data set of up to 47 years, suggest that both precipitation and streamwater chemistry (r(2) >0.84 since 1985) in the Hubbard Brook Experimental Forest (HBEF) will approximate demineralized water within one to three decades. Because such dilute chemistry is unrealistic for surface waters, theoretical baseline compositions have been calculated for precipitation and streamwater: electrical conductivity of 3 and 5 ?S/cm, base cation concentrations of 7 and 39 ?eq/liter, acid-neutralizing capacity values of <1 and 14 ?eq/liter, respectively; and pH 5.5 for both. Significantly large and rapid dilution of surface waters to values even more dilute than proposed for Pre-Industrial Revolution (PIR) conditions has important ecological, biogeochemical and water resource management implications, such as for the success of early reproductive stages of aquatic organisms.

Concurrent Cognitive Processes in Rat Serial Pattern Learning: Item Memory, Serial Position, and Pattern Structure  

PubMed Central

Three experiments examined the processes mediating rat serial pattern learning for rule-consistent versus rule-violating pattern elements (“violation elements”). In all three experiments, rats were trained to press retractable levers in a circular array in a specific sequence for brain stimulation reward (BSR). Experiment 1 examined the role of lever location (L) and element serial position (SP) cues in rats’ ability to learn to anticipate a violation element positioned at the end of a 24-element serial pattern. Rats with L cues either alone or in combination with SP cues learned to anticipate the violation element, whereas those with SP cues alone did not. Rats in groups L and L+SP underwent a series of transfers designed to remove various cues that might have controlled their performance on the violation element. Results indicated that intra-chamber lever location cues mediated performance on the violation element whereas performance on rule-consistent elements within pattern chunks was mediated by an internal mnemonic representation that was insensitive to changes in lever location cues. Experiment 2 examined whether rats could learn to use SP cues alone to anticipate a violation element if it was positioned earlier in a serial pattern. Rats learned to anticipate the violation element based on SP cues alone when it was located in SP6 in a 24-element pattern, but not when it was in SP12. Experiment 3 examined whether or not rats spontaneously encode information about chunk length and the serial position of phrasing cues in serial patterns. Rats were trained to a high criterion on the serial pattern used in Experiment 1, then were challenged with three probe patterns that manipulated both chunk length and overall pattern length. Results indicated that rats spontaneously encoded information regarding the serial position of phrasing cues in relation to chunk length. Thus, rats appear to use at least three cognitive processes concurrently in serial pattern learning tasks, namely, item memory involving external discriminative cues, counting- or timing-like processes for encoding serial position, and rule abstraction for encoding an internal representation of pattern structure.

A review of research on serial murder revealed that the 10 definitions frequently cited failed to adequately represent the totality of serial murder. This article reviews the evolution of these definitions in the professional literature. A more complete definition is proposed that encompasses all types of serial murder, not only those committed by roaming males who act out of lust.

Ritual and signature in serial sexual homicide.  

PubMed

Ritual and signature are fantasy-driven, repetitive crime scene behaviors that have been found to occur in serial sexual homicide. Notwithstanding numerous anecdotal case reports, ritual and signature have rarely been studied empirically. In a national sample of 38 offenders and their 162 victims, we examined behavioral and thematic consistency, as well as the evolution and uniqueness of these crime scene actions. The notion that serial sexual murderers engage in the same rituals and leave unique signatures at every scene was not supported by our data. In fact, the results suggest that the crime scene conduct of this group of offenders is fairly complex and varied. Implications of these findings for forensic assessments and criminal investigations are discussed. PMID:20542945

Blocking in rat serial pattern learning.  

PubMed

Both associative and rule-learning theories have been proposed to account for rat serial pattern learning, but individually they are unable to account for a variety of recent behavioral and psychobiological phenomena. The present study examined the role of rule learning versus discriminative learning in rat pattern learning using a classic associative phenomenon: blocking. Rats learned to press levers in an 8-lever circular array according to a rule-based serial pattern, 123-234-345-456-567-678-781-812, where digits indicate the correct lever in the array for each trial. Each pattern presentation contained a chunk with a final element violation, such as 454 instead of 456. Rats learned in a first phase that a noise signaled the violation chunk; then, a concurrent spatial cue was added in a second phase. A test with spatial cues alone showed that blocking occurred. The results suggest that associative learning mediated cuing of violation elements. Taken together with other behavioral and psychobiological evidence already reported in the literature implicating rule learning when rats learn this pattern in this paradigm, these results implicate multiple concurrent learning processes in rat serial pattern learning.

Beyond the dilute Bose gas  

NASA Astrophysics Data System (ADS)

We discuss problems of three dimensional Bose gases in interaction but non-dilute. We then use the theory of a “weakly interacting” Bose gas recently analyzed as an attempt to obtain further insights into non-dilute systems. In particular, we develop the theory with additional remarks, discussions and a slight modification. The article concludes with a much more detailed analysis of the Bose condensate depletion, as well as a study of the two-fluid model of Tisza and Landau: the coexistence of normal and superfluid liquids at sufficiently low temperatures. In fact, even if it is based on one debatable hypothesis, this non-dilute gas qualitatively leads, up to Landau's “T law”, to a rigorous derivation of most of the previous theoretical studies on liquid helium. It also provides new observations, such as, for example, the coexistence of four subsystems of linked pair of particles: a thermal quasi-particle gas, a frozen jelly, a mixture between the previous ones, and a non-conventional Bose condensation of “Cooper-type pairs”. Moreover, the entropic gas is shown to be different from Landau's form associated with the normal liquid.

Recombinant UL30 antigen-based single serum dilution ELISA for detection of duck viral enteritis.  

PubMed

A recombinant UL30 antigen-based single serum dilution enzyme linked immunosorbent assay (ELISA) was developed to measure specific antibody in the sera of ducks against duck enteritis virus (DEV). The partial UL30 gene of DEV was cloned, expressed, purified and tested for its diagnostic use by designing a single serum dilution enzyme linked immuno-sorbent assay (ELISA). A total of 226 duck sera samples were tested using the assay. A linear relationship was found between the predicted antibody titres at a single working dilution of 1:100 and the corresponding serum titres observed as determined by the standard serial dilution method. Regression analysis was used to determine a standard curve from which an equation was derived which demonstrated this correlation. The equation was then used to convert the corrected absorbance readings of the single working dilution directly into the predicted ELISA antibody titres. The assay proved to be specific, sensitive and accurate as compared to the virus neutralization test with a specificity, sensitivity and accuracy being 96%, 95% and 95% respectively. PMID:22771740

Malingering, coaching, and the serial position effect.  

PubMed

The normal pattern of performance on list-learning tasks is to recall more words from the beginning (primacy) and end (recency) of the list. This pattern is also seen in patients with closed head injury, but malingerers tend to recall less words from the beginning of word lists, leading to a suppressed primacy effect. The present study examined this pattern on both learning trials and delayed recall of the Auditory Verbal Learning Test (AVLT) in 34 persons performing with normal effort, 38 naive malingerers, 33 warned malingerers, and 29 head-injured patients. Both malingering groups had lower scores on the primacy portion of the list during learning trials, while normals and head-injured patients had normal serial position curves. During delayed recall, normals and head-injured patients did better than the two malingering groups on middle and recency portions of the list. Findings suggest that the serial position effect during learning trials may be a useful pattern of performance to watch for when suspicious of malingering. PMID:14589754

Dilute Acid and Autohydrolysis Pretreatment  

NASA Astrophysics Data System (ADS)

Exposure of cellulosic biomass to temperatures of about 120-210°C can remove most of the hemicellulose and produce cellulose-rich solids from which high glucose yields are possible with cellulase enzymes. Furthermore, the use of dilute sulfuric acid in this pretreatment operation can increase recovery of hemicellulose sugars substantially to about 85-95% of the maximum possible versus only about 65% if no acid is employed. The use of small-diameter tubes makes it possible to employ high solids concentrations similar to those preferred for commercial operations, with rapid heat-up, good temperature control, and accurate closure of material balances. Mixed reactors can be employed to pretreat larger amounts of biomass than possible in such small-diameter tubes, but solids concentrations are limited to about 15% or less to provide uniform temperatures. Pretreatment of large amounts of biomass at high solids concentrations is best carried out using direct steam injection and rapid pressure release, but closure of material balances in such “steam gun” devices is more difficult. Although flow of water alone or containing dilute acid is not practical commercially, such flow-through configurations provide valuable insight into biomass deconstruction kinetics not possible in the batch tubes, mixed reactors, or steam gun systems.

Serial powering is a technique to power a large numbers of detector modules using a single power cable and a constant current source. Module power is derived using local shunt regulators. Serial powering is of great interest for large-scale silicon tracking detectors for particle physics with many thousands of densely packed detector modules. We have been operating six ATLAS Semiconductor Tracker (SCT) modules using both serial powering and conventional independent powering. The modules operated stably with no indication of any extra noise sources. We present selected results and discuss the system aspects of serial powering.

Extinction of diffusion flames burning diluted methane and diluted propane in diluted air  

SciTech Connect

A theoretical and experimental investigation of the extinction limits of counterflow diffusion flames burning methane and propane is outlined. A diffusion flame is stabilized between counterflowing streams of a fuel diluted with nitrogen and air diluted with nitrogen. Extinction limits for such flames were measured over a wide parametric range. Results for methane and propane were found to be in appropriate agreement with previous measurements. The experimental results are interpreted by use of activation energy asymptotic theories developed previously. The gas-phase chemical reaction is approximated as a one step, irreversible process with a large value for the ratio of the activation energy characterizing the chemical reaction to the thermal energy in the flame. Equilibrium dissociation of products is neglected. The theoretical predictions are compared with experimental results, and the overall chemical kinetic rate parameters characterizing the gas-phase oxidation of methane and propane in a diffusion flame are deduced. The overall chemical kinetic rate parameters deduced by use of this procedure are valid only at flame temperatures where equilibrium dissociation is negligible. The scalar dissipation rate at extinction is predicted over a wide range.

Serial MR imaging in neonatal cerebral injury.  

PubMed

The results of serial MR imaging of the brain in 32 patients with neonatal cerebral injury who had two or more examinations are reviewed. By comparison with normal age-matched controls, delayed or deficient myelination was identified in eight patients on follow-up examination. Developmental delay was present in all of these patients. In three patients delayed myelination was identified at the first study and was normal at follow-up. These patients improved clinically. The most severe delays or deficits in myelination and the most severe handicaps were present in patients with subcortical and periventricular leukomalacia. Ventricular size was readily assessed. Development of porencephalic cysts at sites of previous hemorrhage and infarction was recognized. The lack of ionizing radiation is of particular importance in follow-up MR of children, and an increasing role for this technique in pediatric developmental neurology appears likely. PMID:3101474

Six cases of serial murder by children and adolescents spanning the past 150 years are presented. The available literature pertaining to this area is reviewed. Each of these six offenders committed sexually homicidal behavior as demonstrated by their expression of erotic interest or engagement in overt sexual behavior at the crime scenes. From a DSM-IV-TR perspective they all exhibited signs of sexual sadism, and their crime characteristics reflected behavior of a more predatory than affective nature. Hands on methods of killing were preferred, i.e., cutting, stabbing, or strangulation. These crimes are extremely rare. Case reports in this area are encouraged to advance our knowledge of these youths. PMID:15211557

Dilution robustness for mean field ferromagnets  

NASA Astrophysics Data System (ADS)

In this work we compare two different random dilutions on a mean field ferromagnet: the first model is built on a Bernoulli diluted graph while the second lives on a Poisson diluted one. While it is known that the two models have, in the thermodynamic limit, the same free energy, we investigate the structural constraints that the two models must fulfill. We rigorously derive for each model the set of identities for the multi-overlap distribution, using different methods for the two dilutions: constraints in the former model are obtained by studying the consequences of the self-averaging of the internal energy density, while in the latter they are obtained by a stochastic stability technique. Finally we prove that the identities emerging in the two models are the same, showing robustness of the ferromagnetic properties of diluted graphs with respect to the details of dilution.

Band anticrossing in dilute nitrides  

SciTech Connect

Alloying III-V compounds with small amounts of nitrogen leads to dramatic reduction of the fundamental band-gap energy in the resulting dilute nitride alloys. The effect originates from an anti-crossing interaction between the extended conduction-band states and localized N states. The interaction splits the conduction band into two nonparabolic subbands. The downward shift of the lower conduction subband edge is responsible for the N-induced reduction of the fundamental band-gap energy. The changes in the conduction band structure result in significant increase in electron effective mass and decrease in the electron mobility, and lead to a large enhance of the maximum doping level in GaInNAs doped with group VI donors. In addition, a striking asymmetry in the electrical activation of group IV and group VI donors can be attributed to mutual passivation process through formation of the nearest neighbor group-IV donor nitrogen pairs.

Short- and long-term memory contributions to immediate serial recognition: evidence from serial position effects.  

PubMed

A long-standing body of research supports the existence of separable short- and long-term memory systems, relying on phonological and semantic codes, respectively. The aim of the current study was to measure the contribution of long-term knowledge to short-term memory performance by looking for evidence of phonologically and semantically coded storage within a short-term recognition task, among developmental samples. Each experimental trial presented 4-item lists. In Experiment 1 typically developing children aged 5 to 6 years old showed evidence of phonologically coded storage across all 4 serial positions, but evidence of semantically coded storage at Serial Positions 1 and 2. In a further experiment, a group of individuals with Down syndrome was investigated as a test case that might be expected to use semantic coding to support short-term storage, but these participants showed no evidence of semantically coded storage and evidenced phonologically coded storage only at Serial Position 4, suggesting that individuals with Down syndrome have a verbal short-term memory capacity of 1 item. Our results suggest that previous evidence of semantic effects on "short-term memory performance" does not reflect semantic coding in short-term memory itself, and provide an experimental method for researchers wishing to take a relatively pure measure of verbal short-term memory capacity, in cases where rehearsal is unlikely.

Serial Marriage: A Heuristic Analysis of an Emerging Family Form  

Microsoft Academic Search

We discuss serial marriage, defined as three or more marriages as a result of repeated divorce, from a heuristic perspective. We estimate the prevalence of the phenomenon and advance hypotheses based on existing empirical, clinical, and theoretical work concerning the development of this life-style and its consequences for family members. We discuss possible outcomes of children in serial marriage families.

Serial power protection for ATLAS silicon strip staves  

NASA Astrophysics Data System (ADS)

Upgrades to the inner tracking detectors at the Super Large Hadron Collider (SLHC) will require more efficient methods of power delivery. Serial power is one architecture that delivers power efficiently by powering a chain of front-end circuits (hybrids) with a common current. A major concern with serial power is the loss of the full hybrid chain due to an open circuit failure of a single hybrid. We propose a method to protect a serial chain of hybrids with emphasis on application to the ATLAS silicon strip upgrade. A prototype protection circuit and its discrete component implementation are described. Results from tests of the protection circuit used with individual “dummy” hybrids and in a system test with a collection of dummy hybrids are given. Finally, a path towards a radiation-hard ASIC implementation is discussed. This work demonstrates that the protection of a serial chain is viable and is not an obstacle to the implementation of serial power.

DAVINCI a Dilute Aperture Coronagraph  

NASA Astrophysics Data System (ADS)

The motivation for DAVINCI was originally to make use of the technology developed for space interferometers like SIM to build a coronagraph from four 1.1m telescopes that was dramatically lower in cost than a 4 5m filled aperture offaxis coronagraph. Our initial studies through team X have shown this cost savings to be real. But a more careful analysis showed that DAVINCI would have an inner working angle of 35mas a factor of 2 smaller than a 2 lambda/D 4 meter coronagraph or 70m external occulter, resulting in a 10X increase in the number of potential Earth-Clone targets. DAVINCI uses a nulling interferometer as a coronagraph, a nulling interferometer is one the few coronagraph architectures that are compatible with segmented and dilute aperture telescopes. Combined with a post coronagraph wavefront sensor several ultra-demanding tolerances of conventional coronagraphs can be relaxed by factors of 100. The post coronagraph wavefront sensor is also much less affected by local and exozodi background than wavefront sensors that use the science camera as the wavefront sensor. The post coronagraph interferometer is also used on ground based extreme AO coronagraphs, GPI, and P1640.

Serial Endosymbiotic Theory (set): the biosemiotic update.  

PubMed

The Serial Endosymbiotic Theory explains the origin of nucleated eukaryotic cells by a merging of archaebacterial and eubacterial cells. The paradigmatic change is that the driving force behind evolution is not ramification but merging. Lynn Margulis describes the symbiogenetic processes in the language of mechanistic biology in such terms as "merging", "fusion", and "incorporation". Biosemiotics argues that all cell-cell interactions are (rule-governed) sign-mediated interactions, i.e., communication processes. As the description of plant communication demonstrates, the biosemiotic approach is not limited to the level of molecular biology, but is also helpful in examining all sign-mediated interactions between organisms on the phenotypic level. If biosemiotics also uses the notions of "language" and "communication" to describe non-human sign-mediated interactions, then the underlying scientific justification of such usage should be critically considered. Therefore, I summarize the history of this discussion held between 1920 and 1980 and present its result, the pragmatic turn. PMID:16988903

Passive serialization in a multitasking environment

In a multiprocessing system having a control program in which data objects are shared among processes, this patent describes a method for serializing references to a data object by the processes so as to prevent invalid references to the data object by any process when an operation requiring exclusive access is performed by another process, comprising the steps of: permitting the processes to reference data objects on a shared access basis without obtaining a shared lock; monitoring a point of execution of the control program which is common to all processes in the system, which occurs regularly in the process' execution and across which no references to any data object can be maintained by any process, except references using locks; establishing a system reference point which occurs after each process in the system has passed the point of execution at least once since the last such system reference point; requesting an operation requiring exclusive access on a selected data object; preventing subsequent references by other processes to the selected data object; waiting until two of the system references points have occurred; and then performing the requested operation.

Volatility and serial correlation: revisiting the LeBaron effect  

NASA Astrophysics Data System (ADS)

According to the LeBaron effect, serial correlation is low when volatility is high and vice-versa. We show that it is true only for the predictable part of the volatility, while volatility which cannot be forecasted is positively linked to serial correlation. Since the mechanism of price formation can be very different in small and large markets we investigate the effect of volatility on intraday serial correlation in Italy (a small market) and U.S. (a large market). We find substantial differences in the impact of volatility in the two markets.

Quantification of serial tumor glucose metabolism  

SciTech Connect

We developed a method to improve the quantitative precision of FDG-PET scans in cancer patients. The total-lesion evaluation method generates a correlation coefficient (r) constrained Patlak parametric image of the lesion together with three calculated glucose metabolic indices: (a) the total-lesion metabolic index ({open_quotes}K{sub T-tie}{close_quotes}, ml/min/lesion); (b) the total-lesion voxel index ({open_quotes}V{sub T-tie}{close_quotes}, voxels/lesion); and (c) the global average metabolic index ({open_quotes}K{sub V-tie}{close_quotes}, ml/min/voxel). The glucose metabolic indices obtained from conventional region of interest (ROI) and multiplane evaluation were used as standards to evaluate the accuracy of the total-lesion evaluation method. Computer simulations and four patients with metastatic melanoma before and after chemotherapy were studied. Computer simulations showed that the total-lesion evaluation method has improved precision (%s.d. <0.6%) and accuracy ({approximately}10% error) compared with the conventional ROI method (%S.d. {approximately}5%; {approximately}25% error). The K{sub T-tie} and V{sub T-tie} indices from human FDG-PET studies using the total-lesion evaluation method showed excellent correlations with the corresponding values obtained from the conventional ROI methods and multiplane evaluation (r{approximately}1.0) and CT lesion volume measurements. This method is a simple but reliable way to quantitatively monitor tumor FDG uptake. The method has several advantages over the conventional ROI method: (a) less sensitive to the ROI definition, (b) no need for image registration of serial scan data and (c) includes tumor volume changes in the global tumor metabolism. 18 refs., 8 figs., 4 tabs.

Automatic registration of serial mammary gland sections  

SciTech Connect

We present two new methods for automatic registration of microscope images of consecutive tissue sections. They represent two possibilities for the first step in the 3-D reconstruction of histological structures from serially sectioned tissue blocks. The goal is to accurately align the sections in order to place every relevant shape contained in each image in front of its corresponding shape in the following section before detecting the structures of interest and rendering them in 3D. This is accomplished by finding the best rigid body transformation (translation and rotation) of the image being registered by maximizing a matching function based on the image content correlation. The first method makes use of the entire image information, whereas the second one uses only the information located at specific sites, as determined by the segmentation of the most relevant tissue structures. To reduce computing time, we use a multiresolution pyramidal approach that reaches the best registration transformation in increasing resolution steps. In each step, a subsampled version of the images is used. Both methods rely on a binary image which is a thresholded version of the Sobel gradients of the image (first method) or a set of boundaries manually or automatically obtained that define important histological structures of the sections. Then distance-transform of the binary image is computed. A proximity function is then calculated between the distance image of the image being registered and that of the reference image. The transformation providing a maximum of the proximity function is then used as the starting point of the following step. This is iterated until the registration error lies below a minimum value.

Chemical potentials in dilute, multicomponent solutions  

SciTech Connect

A new theory of dilute, multicomponent solutions has been derived by expansion about the infinite dilution limit. For dilute, binary mixtures to first order, the theory reduces to that of Debenedetti and Kumar. It is shown that models can be derived within the theory by application of conformal solution theory, fluctuation theory, or their combination. These models have been shown to be useful and accurate in test applications to solutions two solid solutes in a supercritical solvent, quantitatively reproducing the cosolute effect for which correlation with the Peng-Robinson equation of state was only partially successful. Other potential applications include solubility of gases in liquids and solid solubilities in entrained supercritical solvents.

Pauses and durations exhibit a serial position effect.  

PubMed

This article reports evidence of two kinds of serial position effects in immediate serial recall: One involves interresponse pauses, and the other response durations. In forward and backward recall, responding was faster at initial and final positions than at center positions, exhibitinga bow-shaped function relative to serial position. These data were obtained in a spoken recall study in which ungrouped lists of four to six words and postcuing of recall direction were used. The pause pattern is consistent with several models of serial memory, including a distinctiveness model (Brown, Neath, & Chater, 2002) and a version of the ACT-R model augmented with a spontaneous grouping strategy (Maybery, Parmentier, & Jones, 2002). The duration pattern suggests that response articulation depends on the processing context, rather than being modular. PMID:15945208

Dilution of cosmological densities by saxino decay  

SciTech Connect

Saxino decay can generate significant cosmological entropy, and hence dilute theoretical estimates of the present mass density of a given particle species. The dilution factor depends on the saxino and axion masses, and is constrained by the requirement that saxino decay should not affect nucleosynthesis, as well as by the usual requirement that the axion density be less than the critical density. The latter constraint is evaluated carefully, under both the Harari-Sikivie and Davis proposals about the emission spectrum from axionic strings. Uncertainties are carefully evaluated, points of principle are addressed, and with an eye to future numerical simulation the spacing and typical oscillation wavelength of the strings are represented by parameters varying in the range 1 to 3. Within the constraints, the entropy dilution varies from 1 to 10[sup [minus]4]. Only saxinos originating from thermal equilibrium are considered, so that more dilution might arise from nonthermal saxinos.

Three more semantic serial position functions and a SIMPLE explanation.  

PubMed

There are innumerable demonstrations of serial position functions-with characteristic primacy and recency effects-in episodic tasks, but there are only a handful of such demonstrations in semantic memory tasks, and those demonstrations have used only two types of stimuli. Here, we provide three more examples of serial position functions when recalling from semantic memory. Participants were asked to reconstruct the order of (1) two cartoon theme song lyrics, (2) the seven Harry Potter books, and (3) two sets of movies, and all three demonstrations yielded conventional-looking serial position functions with primacy and recency effects. The data were well-fit by SIMPLE, a local distinctiveness model of memory that was originally designed to account for serial position effects in short- and long-term episodic memory. According to SIMPLE, serial position functions in both episodic and semantic memory tasks arise from the same type of processing: Items that are more separated from their close neighbors in psychological space at the time of recall will be better remembered. We argue that currently available evidence suggests that serial position functions observed when recalling items that are presumably in semantic memory arise because of the same processes as those observed when recalling items that are presumably in episodic memory.

Development of serial processing in reading and rapid naming.  

PubMed

Serial rapid automatized naming (RAN) is more strongly related to reading fluency than naming of isolated words, suggesting that the implementation of serial processing may underlie the RAN-reading relationship. In this study, 107 Greek children from Grade 2 and 107 from Grade 6 were tested with discrete and serial naming of digits, objects, and words in 50-item arrays. The correlation between discrete and serial word reading was very high in Grade 2 but only moderate in Grade 6. In confirmatory factor analysis, a reading-naming latent structure fit the Grade 2 data best; in contrast, a serial-discrete structure fit the Grade 6 data. Thus, the superficial longitudinal stability of RAN-reading correlations belies vastly different patterns of interrelations, indicative of changes in the developing cognitive processes underlying both naming and reading. Word fluency tasks in Grade 2 are apparently accomplished largely as a series of isolated individual word naming trials even though multiple individual letters in each word may be processed in parallel. In contrast, specifically serial procedures are applied in Grade 6, presumably via simultaneous processing of multiple individual words at successive levels. It is proposed that this feat requires endogenous control of cognitive cascades. PMID:24077466

Anomalies in diluted 2D antiferromagnets  

NASA Astrophysics Data System (ADS)

The spectrum of quasi-two-dimensional quantum antiferromagnet diluted with spinless impurities is not ``protected'' at long-wavelengths but rather is overdamped at arbitrary concentration of impurities. Specific heat of diluted quasi-2D antiferromagnets is predicted to have a very anomalous behavior due to contribution from the localized states. Other anomalies in the dynamical properties are analyzed and a close agreement of our theoretical results with the recent neutron scattering data for the correlation length is demonstrated.

Stability of purified tuberculin in high dilution.  

PubMed

The authors have investigated the effect of storage on the potency of 5 TU dilutions (5 TU per 0.1 ml) of the purified tuberculin RT 19-21 (Statens Seruminstitut, Copenhagen).Dilutions stored at 2-4 degrees C, 20 degrees C and 37 degrees C for different periods up to 18 months were compared by intradermal testing. About 900 BCG-vaccinated schoolchildren were given duplicate tests and in addition 500 tests were made in BCG-vaccinated guinea-pigs.The results showed unexpected variability. It appeared that this variability was due to unsystematic variations in potency both between dilutions prepared at different times and between ampoules of the same dilution.Because of this variability only limited conclusions could be drawn. At 2-4 degrees C the effect of storage seemed to be very slight, the potency of the dilutions being reduced by less than 25% after 18 months. At the higher temperatures, the decrease in activity was more rapid. Nevertheless, the dilutions could be stored at room temperature (20 degrees C) for some months without any practically significant loss of potency. PMID:13618718

Falsifying Serial and Parallel Parsing Models: Empirical Conundrums and An Overlooked Paradigm  

Microsoft Academic Search

When the human parser encounters a local structural ambiguity, are multiple structures pursued (parallel or breadth-first parsing), or just a single preferred structure (serial or depth-first parsing)? This note discusses four important classes of serial and parallel models: simple limited parallel, ranked limited parallel, deterministic serial with reanalysis, and probabilistic serial with reanalysis. It is argued that existing evidence is

Positional and temporal clustering in serial order memory  

PubMed Central

The well-known finding that responses in serial recall tend to be clustered around the position of the target item has bolstered positional-coding theories of serial order memory. In the present study, we show that this effect is confounded with another well-known finding—that responses in serial recall tend to also be clustered around the position of the prior recall (temporal clustering). The confound can be alleviated by conditioning each analysis on the positional accuracy of the previously recalled item. The revised analyses show that temporal clustering is much more prevalent in serial recall than is positional clustering. A simple associative chaining model with asymmetric neighboring, remote associations, and a primacy gradient can account for these effects. Using the same parameter values, the model produces reasonable serial position curves and captures the changes in item and order information across study-test trials. In contrast, a prominent positional coding model cannot account for the pattern of clustering uncovered by the new analyses.

Cluster scaling in the dilute Ising model  

NASA Astrophysics Data System (ADS)

We consider the cluster mapping method to map the critical point in a site-diluted Ising model onto a correlated site-bond percolation. First, we prove the Coniglio-Klein bond probability has the same form in the dilute Ising model with a proper chosen temperature. Then we study the cluster size distribution near the critical point in 2D dilute Ising model with long range interactions. The power law distribution of the clusters size at the critical point has the same exponent as the mean field Ising critical point, which is consistent with the Harris criterion for the long range Ising model. In addition, we apply this percolation mapping method to identify the nucleating droplet near the spinodal and it shows that the largest cluster size could be used to find the time when nucleating droplet occurs.

Violent cultural factors and serial homicide by males.  

PubMed

Explaining the phenomenon of male serial homicide has usually been approached from a psychiatric perspective. However, recent integrative theory suggests that cultural factors may play a role in shaping the psychology of young males with particular psychiatric and possibly neurological vulnerabilities in such ways as to facilitate converting the motivation to kill into actual behavior. Present results indicated that 34-45% of the interstate variation in rates of serial killer activity could be accounted for by three dimensions of local culture. Higher rates of male serial killer activity were associated with a local state culture supportive of game hunting and military training and a local culture supportive of punitive violence. The findings must be viewed with caution since societal variables are complex and the results are based on correlations which cannot be causally interpreted without more direct evidence of validity.

A combination strategy for tracking the serial criminal  

NASA Astrophysics Data System (ADS)

We build a Geographic Profiling Model to generate the criminal's geographical profile, by combining two complementary strategies: the Spatial Distribution Strategy and the Probability Distance Strategy. In the first strategy, we designate the mean of all the known crime sites as the anchor point, and build a Standard Deviational Ellipse Model, considering the effect of landscape. In the second strategy, we take many factors such as the buffer zone and distance decay theory into consideration and calculate the probability of the offender's residence in a certain area by using the Bayesian Theorem and the Rossmo Algorithm. Then, we combine the result of two strategies and get three search areas suit different conditions of the police to track the serial criminal. Apply the model to the English serial killer Peter Sutcliffe's case, the calculation result shows that the model can effectively be used to track serial criminal.

Information transfer rate with serial and simultaneous visual display formats  

NASA Astrophysics Data System (ADS)

Information communication rate for a conventional display with three spatially separated windows was compared with rate for a serial display in which data frames were presented sequentially in one window. For both methods, each frame contained a randomly selected digit with various amounts of additional display 'clutter.' Subjects recalled the digits in a prescribed order. Large rate differences were found, with faster serial communication for all levels of the clutter factors. However, the rate difference was most pronounced for highly cluttered displays. An explanation for the latter effect in terms of visual masking in the retinal periphery was supported by the results of a second experiment. The working hypothesis that serial displays can speed information transfer for automatic but not for controlled processing is discussed.

A neuropsychiatric developmental model of serial homicidal behavior.

Serial sexual homicide has been the object of intensive study from forensic psychiatric, criminological, developmental, and sociological perspectives. In contradistinction to these approaches, neuropsychiatric concepts and methods have received relatively little attention in this area. In this article we adopt a neuropsychiatric developmental perspective and undertake a review of the psychiatric literature on violence and autism spectrum disorders. Our analysis of this literature suggests the presence of an association between autism spectrum psychopathology and serial homicidal behavior. Recommendations for further research to help clarify the nature of this association are briefly discussed. PMID:15568202

Tumoral calcinosis: Serial images to monitor successful dietary therapy  

SciTech Connect

Tumoral calcinosis involves formation of periarticular calcified soft tissue masses. Experimental evidence suggests a metabolic etiology with dietary restriction of calcium and phosphorus as beneficial therapy. We prospectively monitored serum levels of calcium, phosphorous, alkaline phosphatase, and erythrocyte sedimentation rate (ESR) while successfully treating a patient with tumoral calcinosis. The values were compared with changes on serial radiographic and radionuclide bone and gallium images. Our work suggests using serial serum phosphate levels and the ESR as the most sensitive indications of progress in dietary treatment of tumoral calcinosis.

Interpretation of electron micrographs of single and serial sections.  

PubMed

A method of securing serial sections for electron microscopy is described. Serial sections present certain anomalies of interpretation of a nature such that a complete and detailed three-dimensional reconstruction of the sectioned tissue cannot be made. These anomalies are discussed, as well as those which have been encountered in the interpretation of single sections. Observations of the following kinds have been made in an attempt to elucidate the interpretation of single and serial sections: differing methods of mounting adjacent sections, observation of the same section by high-angle stereoscopy, and examination of sections which have been shadowed prior to and subsequent to electron microscopy. It is found that the appearance of sections is independent of the choice of side to be placed against the formvar films. Stereoscopy shows that the appearance of fine structures is strongly dependent upon the direction of the penetrating electron beam with respect to the plane of the structures. Stereoscopy, combined with shadowing, shows quantitatively that extensive sublimation of polymer occurs upon normal exposure in the electron microscope. Observation of sections shadowed prior to electron microscopy indicates that varying amounts of material are removed between sections by the action of microtomy; i.e., it is probable that the sum of the thicknesses of several serial sections is considerably less than the total thickness of material removed from the block. It is believed that this effect, combined with the effect of sublimation, aids in explaining the failure of adjacent sections to exhibit continuity in their detailed structures. PMID:13242595

Forensic sexology: paraphilic serial rape (biastophilia) and lust murder (erotophonophilia).  

PubMed

Forensic sexology is not synonymous with either forensic psychiatry or forensic psychology. It is a specialty in its own right, and is needed in the courtroom. Paraphilic sex offenders on trial are misrepresented as being, by their own choice, psychopathic or sociopathic deviates. They are unable to explain their paraphilic criminality to either themselves or society. In a case of serial rape and serial lust murder here presented, the contributory causes are examined and differentiated as hereditary predisposition, hormonal functioning; pathological relationships, sexual abuse; and syndrome overlap with bipolar disorder, schizoid disorder, antisocial personality disorder, epilepsy, and multiple personality. The precipitating causes were differentiated as childhood head injuries, and adult head injury at age 20. Left impact trauma and sexological trauma were sequelae of the adult injury. The full range of diagnostic resources was not available for a prisoner on death row. Capital punishment has not prevented the reemergence in each new generation of serial rape and serial lust murder as an epidemiological, public health problem. Punishment is an ineffectual substitute for epidemiological research into cause, effect, and prevention. PMID:2327516

Dilution physics modeling: Dissolution/precipitation chemistry  

SciTech Connect

This report documents progress made to date on integrating dilution/precipitation chemistry and new physical models into the TEMPEST thermal-hydraulics computer code. Implementation of dissolution/precipitation chemistry models is necessary for predicting nonhomogeneous, time-dependent, physical/chemical behavior of tank wastes with and without a variety of possible engineered remediation and mitigation activities. Such behavior includes chemical reactions, gas retention, solids resuspension, solids dissolution and generation, solids settling/rising, and convective motion of physical and chemical species. Thus this model development is important from the standpoint of predicting the consequences of various engineered activities, such as mitigation by dilution, retrieval, or pretreatment, that can affect safe operations. The integration of a dissolution/precipitation chemistry module allows the various phase species concentrations to enter into the physical calculations that affect the TEMPEST hydrodynamic flow calculations. The yield strength model of non-Newtonian sludge correlates yield to a power function of solids concentration. Likewise, shear stress is concentration-dependent, and the dissolution/precipitation chemistry calculations develop the species concentration evolution that produces fluid flow resistance changes. Dilution of waste with pure water, molar concentrations of sodium hydroxide, and other chemical streams can be analyzed for the reactive species changes and hydrodynamic flow characteristics.

A Dilute Three-Dimensional XY Ferromagnet  

NASA Astrophysics Data System (ADS)

Iron(III) bis(diselenocarbamate) chloride is a pentacoordinate molecular ferromagnet ordering near 3.4 K. The unusual site symmetry yields a spin 3/2 ground state. A rather substantial zero-field splitting occurs, with D positive, leading to XY like magnetic properties at low temperature. Significant exchange interactions occur between molecules via Fe-Se...Se-Fe contacts, without substantial spatial anisotropy. It is of interest to examine the effects of diamagnetic dilution on such a system. We have succeeded in dissolving modest amounts of diamagnetic Zn(II) bis(dithiocarbamate) into the Fe(III) system lattice. Analysis of susceptibility and magnetization data reveals a sizable reduction of the magnetic ordering temperature of the pure material on dilution. Comparisons are possible with previous work in which dilution of the approximate 3D-Ising system Fe(III) bis(dithiocarbamate) chloride was studied. *Supported by NSF-Solid State Chemistry-Grant No. DMR-0085662 and by a grant from the Petroleum Research Fund of the American Chemical Society.

Effect of type III antifreeze protein dilution and mutation on the growth inhibition of ice.  

PubMed Central

Mutation of residues at the ice-binding site of type III antifreeze protein (AFP) not only reduced antifreeze activity as indicated by the failure to halt ice crystal growth, but also altered ice crystal morphology to produce elongated hexagonal bipyramids. In general, the c axis to a axis ratio of the ice crystal increased from approximately 2 to over 10 with the severity of the mutation. It also increased during ice crystal growth upon serial dilution of the wild-type AFP. This is in marked contrast to the behavior of the alpha-helical type I AFPs, where neither dilution nor mutation of ice-binding residues increases the c:a axial ratio of the ice crystal above the standard 3.3. We suggest that the ice crystal morphology produced by type III AFP and its mutants can be accounted for by the protein binding to the prism faces of ice and operating by step growth inhibition. In this model a decrease in the affinity of the AFP for ice leads to filling in of individual steps at the prism surfaces, causing the ice crystals to grow with a longer c:a axial ratio.

Insect morphological diversification through the modification of wing serial homologs.  

PubMed

Fossil insects living some 300 million years ago show winglike pads on all thoracic and abdominal segments, which suggests their serial homology. It remains unclear whether winglike structures in nonwinged segments have been lost or modified through evolution. Here, we identified a ventral lateral part of the body wall on the first thoracic segment, the hypomeron, and pupal dorsolateral denticular outgrowths as wing serial homologs in the mealworm beetle Tenebrio molitor. Both domains transform into winglike structures under Hox RNA interference conditions. Gene expression and functional analyses revealed central roles for the key wing selector genes, vestigial and scalloped, in the hypomeron and the denticular outgrowth formation. We propose that modification, rather than loss, of dorsal appendages has provided an additional diversifying mechanism of insect body plan. PMID:23493422

Jacob--the case of a serial killer.  

PubMed

This paper describes a rare forensic psychiatric syndrome which has been the subject of massive publicity in the last decade. Despite the widespread interest, the psychodynamic process whereby a person becomes a serial murderer remains largely unknown. "Jacob" was convicted of a series of murders that he carried out over a decade. The case material is based on the psychiatric reports that were presented to the court and the many articles published in the local press at the time. Despite the limitations imposed by the material, the available information on "Jacob" bears some similarity to the phenomenological and psychodynamic models described in the literature. An attempt is made to understand the transformation of a person into a serial killer considering the life events, psychopathology and stressors that lead to the emergence from the world of imagination and fantasy of a potential murderer to the deeds that comprise the syndrome.

[Some criminological and psychopathologic reflexions about serial crimes].

This article reviews the concept of serial crime, including murder as well as any action for the purpose of inflicting bodily harm upon any person. It characterizes three types of multi-murderers: serial killers, mass murderers, and spree killers. These offenders often have a specific (ritual) behavior that is idiosyncratic and repeated on each crime, which allows the psychological profiling of the murderer. Examples, a psychopathological background, and a description of both their criminal behavior and dynamics are provided for each of these criminals. They are further classified according to their different motivations: psychotic, prophetic or enlightened, pleasure, secondary or pecuniary profits, power or control. Finally, the author shares his personal experience over 20 years in the assessment of sexual offenders. PMID:22091451

The study objective was to determine whether short-term serial magnetoencephalographic (MEG) measurements would increase the odds in favor of obtaining fetal auditory evoked responses in normal fetuses. The recordings were performed in two phases using the newly developed 151-channel fetal MEG system, superconducting quantum interference device array for reproductive assessment. Ten pregnant subjects with gestational ages ranging from 30-35 weeks were recruited to participate. Daily recordings were performed over a minimum of 3 days during 1 week of gestation and repeated in the same subjects between 36 and 40 weeks gestation. In 80% of subjects, auditory evoked responses were detected at least once. In healthy fetuses, serial recordings over a short span of time increased the rate of detecting fetal evoked response.

Serial electrophysiological study on two infants with acute facial palsy.  

PubMed

Two infants with acute unilateral facial palsy were examined serially as to the electrically and mechanically elicited blink reflex, photo-evoked eyelid microvibration and auditory brainstem response (ABR). The results indicated that in hemifacial palsy beside the affection of the facial nerve also central pathways in the brainstem were involved in the pathogenetic processes. In particular, a neurapraxic change of the facial nerve itself in one case played an important role in pathogenesis, while a wide spread involvement was observed in another case. The clinical recovery of a patient with a wide spread involvement was more prolonged. We suggest that serial determinations of blink reflexes and ABR are helpful in clarifying the underlying pathogenetic processes concerning the brainstem affection during facial nerve palsy.

Serial position effects in social transmission of food preference.  

PubMed

The serial position effect in Long-Evans rats was evaluated in two experiments. In Experiment 1, the effect in a group for which an interstimulus interval (ISI) was introduced between items in a list of demonstrators was compared with that in a group without an ISI. With an ISI, a recency effect was produced. In Experiment 2, a serial position effect group was compared with four groups in which either the distinctiveness or the context of the middle item was changed, relative to the items on either side of it. A von Restorff effect was produced when a rat from a different strain was used as a demonstrator in Position 2. The results for Experiment 1 are discussed in relation to interstimulus effects in monkeys and those for Experiment 2 with respect to changes in the physical properties of middle items.

Correcting for serial dependence in studies of respiratory dynamics.  

PubMed

Understanding the physiological impact of drug treatments on patients is important in assessing their performance and determining possible side effects. While this effect might be best determined in individual subjects, conventional methods assess treatment performance by averaging a physiological measure of interest before and after drug administration for n subjects. Summarizing large numbers of time-series observations in two means for each subject in this way results in significant information loss. Treatment effect can instead be analyzed in individual subjects. Because serial dependence of observations from the same animal must then be considered, methods that assume independence of observations, such as the t-test and z-test, cannot be used. We address this issue in the case of respiratory data collected from anesthetized rats that were injected with a dopamine agonist. In order to accurately assess treatment effect in time-series data, we begin by formulating a method of conditional likelihood maximization to estimate the parameters of a first-order autoregressive (AR) process. We show that treatment effect of a dopamine agonist can be determined while incorporating serial effect into the analysis. In addition, while maximum likelihood estimators of a large sample with independent observations may converge to an asymptotically normal distribution, this result of large sample theory may not hold when observations are serially dependent. In this case, a parametric bootstrap comparison can be used to approximate an appropriate measure of uncertainty. PMID:22254658

Cognitive, emotional and social markers of serial murdering.  

PubMed

Although criminal psychopathy is starting to be relatively well described, our knowledge of the characteristics and scientific markers of serial murdering is still very poor. A serial killer who murdered more than five people, KT, was administered a battery of standardized tests aimed at measuring neuropsychological impairment and social/emotional cognition deficits. KT exhibited a striking dissociation between a high level of emotional detachment and a low score on the antisocial behavior scale on the Psychopathy Checklist-Revised (PCL-R). The Minnesota Multiphasic Personality Inventory-2 showed a normal pattern with the psychotic triad at borderline level. KT had a high intelligence score and showed almost no impairment in cognitive tests sensitive to frontal lobe dysfunction (Wisconsin Card Sorting Test, Theory of Mind, Tower of London, this latter evidenced a mild impairment in planning performance). In the tests on moral, emotional and social cognition, his patterns of response differed from matched controls and from past reports on criminal psychopaths as, unlike these individuals, KT exhibited normal recognition of fear and a relatively intact knowledge of moral rules but he was impaired in the recognition of anger, embarrassment and conventional social rules. The overall picture of KT suggests that serial killing may be closer to normality than psychopathy defined according to either the DSM IV or the PCL-R, and it would be characterized by a relatively spared moral cognition and selective deficits in social and emotional cognition domains.

Effect of dilution on recovery of bacteria from blood.

The multiplication rate of bacteria in undiluted blood containing sodium polyanethol sulfonate was compared with growth rates obtained in dilutions of blood ranging from 1:2 to 1:8. Although all organisms tested grew in the undiluted blood, increased growth rates were seen in the 1:2 dilution. Further dilution resulted in growth rates equivalent to that obtained with the 1:2 dilution. In view of these results, we question the present recommendations that blood be diluted 1:10 or 1:20.

Citation patterns in the health sciences: implications for serials/monographic fund allocation.  

PubMed

This study sought to determine optimal serial-to-monograph ratios for collection development by comparing citation frequency with current library practice. Internal medicine literature cited an average of 88% serial references and 12% monographs. In an observational study, teaching physicians on internal medicine rounds cited 89.5% serials and 10.5% monographs to student teams. By contrast, health sciences libraries included in the Houston statistics spend an average of 79% of acquisitions budgets for serials and 21% for monographs. An 88:12 acquisitions budget ratio would be more appropriate, reflecting actual use of serials and monographs in the health sciences. PMID:8428188

Effective viscosity of dilute bacterial suspensions  

NASA Astrophysics Data System (ADS)

This dissertation explores the bulk (volume averaged) properties of suspensions of microswimmers in a fluid. A microswimmer is a microscopic object that propels itself through a fluid. A common example of a microswimmer is a bacterium, such as Bacillus subtilis. Our particular interest is the bulk rheological properties of suspensions of bacteria -- that is, studying how such a suspension deforms under the application of an external force. In the simplest case, the rheology of a fluid can be described by a scalar effective viscosity. The goal of this dissertation is to find explicit formulae for the effective viscosity in terms of known geometric and physical parameters characterizing bacteria and use them to explain experimental observations. Throughout the dissertation, we consider bacterial suspensions in the dilute limit, where bacteria are assumed to be so far apart that interactions between them are negligible. This simplifies calculations significantly and is the regime in which the most striking experimental results have been observed. We first study suspensions of self-propelled particles using a two-dimensional (2D) Partial Differential Equation (PDE) model. A bacterium is modeled as a disk in 2D with self-propulsion provided by a point force in the fluid. A formula is obtained for the effective viscosity of such suspensions in the dilute limit. This formula includes the two terms that are found in the 2D version of Einstein's classical result for a passive suspension of spheres. To this, our main contribution is added, an additional term due to self-propulsion which depends on the physical and geometric properties of the suspension. This work demonstrates how bacterial self-propulsion can alter the viscosity of a fluid and highlights the importance of bacterial orientation. Next, we present a more realistic PDE model for dilute suspensions of swimming bacteria in a three-dimensional fluid. In this work, a bacterium is modeled as a prolate spheroid with self-propulsion once more provided by a point force. Furthermore, the bacterium is subject to a random torque in order to model tumbling (random reorientation). This model is used to calculate the effective viscosity of the suspension from the microscopic details of the interaction of an elongated body with a prescribed background flow, once more in the dilute limit. Due to a bacterium's asymmetric shape (in particular, unlike the case of rotationally symmetric bacteria used in the first model), interactions with generic planar background flows cause the bacterium to preferentially align in certain directions. Due to the random torque, the steady-state distribution of orientations is unique for a given background flow. Under this distribution of orientations, self-propulsion produces a reduction in the effective viscosity. For sufficiently weak background flows, the effect of self-propulsion on the effective viscosity dominates all other contributions, leading to an effective viscosity of the suspension that is lower than the viscosity of the ambient fluid. This is in qualitative agreement with recent experiments on suspensions of Bacillus subtilis. Finally, we present a method that can be used to rigorously justify our effective viscosity formulae. In particular, we present a mathematical proof of Einstein's formula for the effective viscosity of a dilute suspension of spheres when the spheres are centered on the vertices of a cubic lattice. This proof admits a generalization to other particle shapes and the inclusion of self-propulsion. We keep the size of the container finite in the dilute limit and consider boundary effects. Einstein's formula is recovered as a first-order asymptotic expansion of the effective viscosity in the volume fraction o. To rigorously justify this expansion, we obtain an explicit upper and lower bound on the effective viscosity and show that they match to order o3/2.

Bond diluted anisotropic quantum Heisenberg model  

NASA Astrophysics Data System (ADS)

Effects of the bond dilution on the critical temperatures, phase diagrams and the magnetization behaviors of the isotropic and anisotropic quantum Heisenberg model have been investigated in detail. For the isotropic case, bond percolation threshold values have been determined for several numbers of two (2D) and three (3D) dimensional lattices. In order to investigate the effect of the anisotropy in the exchange interaction on the results obtained for the isotropic model, a detailed investigation has been made on a honeycomb lattice. Some interesting results, such as second order reentrant phenomena in the phase diagrams have been found.

Europium Nitride: A Novel Diluted Magnetic Semiconductor  

NASA Astrophysics Data System (ADS)

Europium nitride is semiconducting and contains nonmagnetic Eu3+, but substoichiometric EuN has Eu in a mix of 2+ and 3+ charge states. We show that at Eu2+ concentrations near 15%–20% EuN is ferromagnetic with a Curie temperature as high as 120 K. The Eu3+ polarization follows that of the Eu2+, confirming that the ferromagnetism is intrinsic to the EuN which is, thus, a novel diluted magnetic semiconductor. Transport measurements shed light on the likely exchange mechanisms.

Magnetopolaron effect in diluted semimagnetic semiconductors  

NASA Astrophysics Data System (ADS)

Phonon-assisted self-trapping of free carrier is considered in diluted semimagnetics. It is shown that the binding energy of free magnetic polaron can be substantially larger when the 'spin-phonon' coupling is taken into account. For the particular case of 'soft' lattice dynamics the region of stability for hole-induced polaron can be promoted to the temperature of tenths of degrees and magnetic field of a few Tesla. The possible hybridized excitations with the partition of free magnetic polaron are discussed in semimagnetic semiconductors.

Subfemtosecond magnetization dynamics in diluted ferromagnetic metals  

NASA Astrophysics Data System (ADS)

The magnetic screening of localized excitations in Ni and Fe ferromagnetic metal hosts has been investigated by magnetic circular dichroism of inelastic x-ray resonant scattering in perpendicular geometry at the Ni L2,3 absorption region. The method probes the spin-dependent screening by the electron population initially in thermodynamic equilibrium. A screening time constant of 1.5 fs in Ni metal has been reported in literature. Here an upper limit of 150 as is set for the screening time constant in Fe metal by measuring the scattering from Ni impurities in dilute Fe metal. The present time scale is among the shortest experimentally investigated in magnetic phenomena.

The design, construction, and operational characteristics of a continuous THe--UHe dilution refrigerator specifically built for use in muon spin relaxation ( SR) measurements at LAMPF are described in this paper. The refrigerator is unique in that it makes an angle of 30 with respect to horizontal: a requirement imposed by the previously existing physical constraints of the SR spectrometer. Additionally, the refrigerator and associated gas handling units are portable so as to facilitate ease of movement into and out of the muon beam. Typical parameters describing refrigerator performance are 60-mK base temperature with 22- W cooling capacity at 100 mK.

Serial position memory in the visual-spatial domain: reconstructing sequences of unfamiliar faces.  

PubMed

In two studies we presented pictures of unfamiliar faces one at a time, then presented the complete set at test and asked for serial reconstruction of the order of presentation. Serial position functions were similar to those found with verbal materials, with considerable primacy and one item recency, position errors that were mainly to the adjacent serial position, a visual similarity effect, and effects of articulatory suppression that did not interact with the serial position effect or with the similarity effect. Serial position effects were found when faces had been seen for as little as 300 ms and after a 6-s retention interval filled with articulatory suppression. Serial position effects found with unfamiliar faces are not based on verbal encoding strategies, and important elements of serial memory may be general across modalities. PMID:16194941

Neutron scattering study of dilute supercritical solutions  

SciTech Connect

Dilute solutions in supercritical solvents exhibit interesting microstructures that are related to their dramatic macroscopic behavior. In typical attractive solutions, solutes are believed to be surrounded by clusters of solvent molecules, and solute molecules are believed to congregate in the vicinity of one another. Repulsive solutions, on the other hand, exhibit a local region of reduced solvent density around the solute with solute-solute congregation. Such microstructures influence solubility, partial molar volume, reaction kinetics, and many other properties. We have undertaken to observe these interesting microstructures directly by neutron scattering experiments on dilute noble gas systems including Ar. The three partial structure factors for such systems and the corresponding pair correlation functions can be determined by using the isotope substitution technique. The systems studied are uniquely suited for our objectives because of the large coherent neutron scattering length of the isotope {sup 36}Ar and because of the accurate potential energy functions that are available for use in molecular simulations and theoretical calculations to be compared with the scattering results. We will describe our experiment, the unique apparatus we have built for it, and the neutron scattering results from our initial allocations of beam time. We will also describe planned scattering experiments to follow those with noble gases, including study of long-chain molecules in supercritical solvents. Such studies will involve hydrocarbon mixtures with and without deuteration to provide contrast.

Flow Estimation by Indicator Dilution (Bolus Injection)  

PubMed Central

Indicator dilution techniques used for the estimation of flow (F), mean transit time (t?), dispersion (?), and mean transit time volume (V) in the circulation are subject to error when (1) flow is not steady and (2) concentrations are obtained by sampling at a constant rate (time averaging) rather than at rates proportional to the instantaneous flow past the sampling site (volume averaging). Using a simple descriptive model for indicator transport, the effects of simulated aortic flow or of sinusoidal flow of widely variable frequency were assessed. Errors in estimates of F, t?, ?, and V are greater with bolus injections than with constant-rate injections. Errors are roughly proportional to the amplitude of variation in flow. They are maximal when the period of flow fluctuation is similar to the passage time of dye dilution curve, which, for the human central circulation, is about the time for one respiratory cycle. With sinusoidal flow between 50% and 150% of the mean flow, errors were at worst up to 60% in F, 30% in t?, 50% in ?, and 70% in V, with a bimodal distribution. Errors are minimal at cardiac frequencies. The troublesome lower frequencies can be avoided. Preliminary tests of a method for converting time- to volume-averaged concentrations gave encouraging results

Motor-mediated microtubule self-organization in dilute and semi-dilute filament solutions.  

SciTech Connect

We study molecular motor-induced microtubule self-organization in dilute and semi-dilute filament solutions. In the dilute case, we use a probabilistic model of microtubule interaction via molecular motors to investigate microtubule bundle dynamics. Microtubules are modeled as polar rods interacting through fully inelastic, binary collisions. Our model indicates that initially disordered systems of interacting rods exhibit an orientational instability resulting in spontaneous ordering. We study the existence and dynamic interaction of microtubule bundles analytically and numerically. Our results reveal a long term attraction and coalescing of bundles indicating a clear coarsening in the system; microtubule bundles concentrate into fewer orientations on a slow logarithmic time scale. In semi-dilute filament solutions, multiple motors can bind a filament to several others and, for a critical motor density, induce a transition to an ordered phase with a nonzero mean orientation. Motors attach to a pair of filaments and walk along the pair bringing them into closer alignment. We develop a spatially homogenous, mean-field theory that explicitly accounts for a force-dependent detachment rate of motors, which in turn affects the mean and the fluctuations of the net force acting on a filament. We show that the transition to the oriented state can be both continuous and discontinuous when the force-dependent detachment of motors is important.

[Vertebral artery dissection without subarachnoid hemorrhage studied by serial angiography].  

PubMed

We presented six cases we have encountered of vertebral artery dissection without subarachnoid hemorrhage followed by serial angiography. All six patients suffered from severe headache and/or nuchal pain at onset. Pain was acute at onset, with severe intensity and sharp quality and was located unilaterally on the dissection side. Only two patients showed neurological deficits. CT scan disclosed no abnormalities in any of the cases and angiography performed at the acute stage showed varied findings. The so-called pearl and string sign, which has been considered the most common finding of this disorder, was observed in only two cases. The definite diagnosis was able to be finally made by serial angiography. During the first few months after onset, dynamic changes of angiographical findings were demonstrated in all cases. During these periods, although transient deterioration of the angiographical findings was shown in four cases, spontaneous healing or improvement was finally recognized in all cases except one which progressed to total occlusion. In contrast to this, in the chronic stage, no changes of angiographical findings occurred in any of the cases. All six patients were treated non-surgically. All showed almost total recovery from symptoms and returned to their previous life styles. There were no cases of recurrent deterioration of symptoms in spite of the changes indicated by the angiographical findings. Our experience with these patients suggests that the actual incidence of vertebral artery dissection without subarachnoid hemorrhage may be much higher than is usually thought, and that the natural course of this disorder seems to be usually favorable. However, longer follow-up study and an analysis of a larger number of cases are required to identify the true incidence and the natural course of this disorder. In addition, we would like to emphasize that accurate diagnosis is most important. If it is clinically suspected, careful investigations including serial angiography should be carried out for the diagnosis of this disorder. PMID:8692370

High-Resolution Protein Structure Determination by Serial Femtosecond Crystallography

Structure determination of proteins and other macromolecules has historically required the growth of high-quality crystals sufficiently large to diffract x-rays efficiently while withstanding radiation damage. We applied serial femtosecond crystallography (SFX) using an x-ray free-electron laser (XFEL) to obtain high-resolution structural information from microcrystals (less than 1 micrometer by 1 micrometer by 3 micrometers) of the well-characterized model protein lysozyme. The agreement with synchrotron data demonstrates the immediate relevance of SFX for analyzing the structure of the large group of difficult-to-crystallize molecules.

To prove that she is right, she must rely on instrumentation designed and tested by a team of students from the local university. Students read the case, then design and build a device for the detection of blood stains. The case was developed for use in an undergraduate laboratory course sequence in photonics for junior and senior level students. It would be suitable for any undergraduate course in physics, chemistry, or electrical engi eering that covers topics in optics, photonics, or spectroscopy.

Inorganic positive uniaxial films fabricated by serial bideposition.  

PubMed

The physical vapor deposition process of serial bideposition is adapted to the fabrication of uniaxial optical coatings. During the coating process the vapor impinges at an angle of incidence of about 70 on to the substrate, and a stepwise axial rotation with 90 increments causes a columnar structure to grow normal to the substrate. Symmetry considerations that follow from the choice of 90 for the stepwise increment ensure that the film is achiral and has negligible in-plane linear birefringence. Optical characterization techniques confirm that films of tantalum oxide, titanium oxide and zirconium oxide are positive uniaxial with ne -no in the range 0.10 to 0.14. PMID:19483917

Constant-delay MSB-first bit-serial adder  

NASA Astrophysics Data System (ADS)

A new MSB-first bit-serial adder/subtracter architecture is proposed. The architecture utilizes a modified Manchester carry chain to accommodate the carry from the future LSB's. The carry chain is shown to have the constant delay of two AND gates and one XOR gate regardless of the operand width, which allows a fast constant operational clock frequency. When compared to the conventional parallel addition approach where the operand bits are stored and then added in parallel, the proposed architecture also provides a significant area saving. It is also shown that the proposed architecture can be generalized for radix-r operands.

The design supports a party line approach, with up to 16 crates on a single twisted pair for data transfers, plus another pair for prompt L response. The bit rate is 5 megabits/s, and complete transaction times of about 10 ..mu..s are achieved for 16-bit data transfers over cables up to 1000 feet long. One of the primary objects of the design was simplicity - there are approximately 60 chips in the two-board unit.

Sequential angulation, spatial dispersion and consistency of distance attack patterns from home in serial murder, rape and burglary  

Microsoft Academic Search

Three related measures of spatial movement (sequential angulation, spatial dispersion and consistency of distance in attack target) were compared across three serial offence types: serial homicide (n=35), serial rape (n=41) and serial burglary (n=30). In each case, each offender had committed at least five offences. “Spatial dispersion”, defined as the extent to which an offender distributes his offences across either

Characterization of the Dilute Ising Antiferromagnet  

SciTech Connect

A spin glass is a magnetic ground state in which ferromagnetic and antiferromagnetic exchange interactions compete, thereby creating frustration and a multidegenerate state with no long range order. An Ising system is a system where the spins are constrained to lie parallel or antiparallel to a primary axis. There has been much theoretical interest in the past ten years in the effects of applying a magnetic field transverse to the primary axis in an Ising spin glass at low temperatures and thus study phase transitions at the T=0 limit. The focus of this study is to search for and characterize a new Ising spin glass system. This is accomplished by site diluting yttrium for terbium in the crystalline material TbNi{sub 2}Ge{sub 2}. The first part of this work gives a brief overview of the physics of rare earth magnetism and an overview of experimental characteristics of spin glasses. This is followed by the methodology used to manufacture the large single crystals used in this study, as well as the measurement techniques used. Next, a summary of the results of magnetic measurements on across the dilution series from pure terbium to pure yttrium is presented. This is followed by detailed measurements on particular dilutions which demonstrate spin glass behavior. Pure TbNi{sub 2}Ge{sub 2} is an Ising antiferromagnet with a several distinct metamagnetic states below 17 K. As the terbium is alloyed with yttrium, these magnetic states are weakened in a consistent manner, as is seen in measurements of the transition temperatures and analysis of Curie-Weiss behavior at high temperature. At low concentrations of terbium, below 35%, long range order is no longer present and a spin-glass-like state emerges. This state is studied through various measurements, dc and ac susceptibility, resistivity, and specific heat. This magnetic behavior was then compared to that of other well characterized spin glasses. It is concluded that there is a region of concentration s for which a spin glass state is formed with the best spin glasses existing between the concentration of 25% and 30%.

Fermi Surface of the Most Dilute Superconductor  

NASA Astrophysics Data System (ADS)

The origin of superconductivity in bulk SrTiO3 is a mystery since the nonmonotonous variation of the critical transition with carrier concentration defies the expectations of the crudest version of the BCS theory. Here, employing the Nernst effect, an extremely sensitive probe of tiny bulk Fermi surfaces, we show that, down to concentrations as low as 5.5×1017cm-3, the system has both a sharp Fermi surface and a superconducting ground state. The most dilute superconductor currently known therefore has a metallic normal state with a Fermi energy as little as 1.1 meV on top of a band gap as large as 3 eV. The occurrence of a superconducting instability in an extremely small, single-component, and barely anisotropic Fermi surface implies strong constraints for the identification of the pairing mechanism.

Stable isotope dilution assays in mycotoxin analysis.  

PubMed

The principle and applications of stable isotope dilution assays (SIDAs) in mycotoxin analysis are critically reviewed. The general section includes historical aspects of SIDAs, the prerequisites and limitations of the use of stable isotopically labelled internal standards, and possible calibration procedures. In the application section actual SIDAs for the analysis of trichothecenes, zearalenone, fumonisins, patulin, and ochratoxin A are presented. The syntheses and availability of labelled mycotoxins for use as internal standards is reviewed and specific advances in food analysis and toxicology are demonstrated. The review indicates that LC-MS applications, in particular, require the use of stable isotopically labelled standards to compensate for losses during clean-up and for discrimination due to ion suppression. As the commercial availability of these compounds continues to increase, SIDAs can be expected to find expanding use in mycotoxin analysis. PMID:18060393

Electronic properties of dilute Bismide alloys  

NASA Astrophysics Data System (ADS)

The alloying of GaAs with small amounts of N or Bi results in a large reduction of the fundamental band gap, leading to the so called ``giant band gap bowing''. GaAs1-xNx has been the subject of intense investigation in recent years; however the lower mobility of the dilute nitride alloys limits its use for device applications. Bi incorporation is predicted to mainly perturb the valence band and does not significantly affect the electron mobility, thus promising better device performance. We report photoluminescence (PL) measurements of GaAs1-xBix epilayers grown by MBE, carried about at different temperatures (4 - 300K), with above-band gap and selective excitation. Time-resolved PL measurements were also carried out to study the carrier lifetimes of the Bi-related states in these samples.

Dilute Oxygen Combustion - Phase 3 Report  

SciTech Connect

Dilute Oxygen Combustion (DOC) burners have been successfully installed and operated in the reheat furnace at Auburn Steel Co., Inc., Auburn, NY, under Phase 3 of the Dilute Oxygen Combustion project. Two new preheat zones were created employing a total of eight 6.5 MMBtu/hr capacity burners. The preheat zones provide a 30 percent increase in maximum furnace production rate, from 75 tph to 100 tph. The fuel rate is essentially unchanged, with the fuel savings expected from oxy-fuel combustion being offset by higher flue gas temperatures. When allowance is made for the high nitrogen level and high gas phase temperature in the furnace, measured NOx emissions are in line with laboratory data on DOC burners developed in Phase 1 of the project. Burner performance has been good, and there have been no operating or maintenance problems. The DOC system continues to be used as part of Auburn Steel's standard reheat furnace practice. High gas phase temperature is a result of the high firing density needed to achieve high production rates, and little opportunity exists for improvement in that area. However, fuel and NOx performance can be improved by further conversion on furnace zones to DOC burners, which will lower furnace nitrogen levels. Major obstacles are cost and concern about increased formation of oxide scale on the steel. Oxide scale formation may be enhanced by exposure of the steel to higher concentrations of oxidizing gas components (primarily products of combustion) in the higher temperature zones of the furnace. Phase 4 of the DOC project will examine the rate of oxide scale formation in these higher temperature zones and develop countermeasures that will allow DOC burners to be used successfully in these furnace zones.

A new technique of correcting emittance dilutions in linear colliders  

NASA Astrophysics Data System (ADS)

This article describes a new method of reducing the transverse emittance dilution in linear colliders due to both transverse wakefields and dispersive errors. The technique is a generalization of the dispersion-free [1] correction algorithm; the dilutions are corrected locally by varying the beam trajectory. This technique will complement the BNS damping [2] method which primarily corrects the dilutions resulting from coherent betatron oscillations. Finally, the results of simulations are presented demonstrating the viability of the technique.

Overlapping mental operations in serial performance with preview.  

PubMed

Dual-task research has revealed a response-selection bottleneck: response selection cannot occur simultaneously in two different tasks, though perceptual processing may overlap response selection (Welford, 1952; Pashler & Johnston, 1989). In serial performance with preview, the same task is performed repeatedly, but stimuli are available well before response. Does the dual-task bottleneck limit the rate of responding in this situation, despite the fact that task set need not change? Four experiments examined manual responses to letters, varying stimulus preview. Preview increased RTs for the first response and reduce the subsequent inter-response intervals (IRIs). Preview also reduced the effect of visual intensity and response duration on IRIs, whereas effects of stimulus-response mapping variables were unchanged. These results indicate that the response-selection bottleneck limits serial performance, just as it limits concurrent performance of two unrelated tasks. This implies that the response-selection bottleneck is not caused by the need to switch task set. PMID:8177960

Identifying Cell Class Specific Losses from Serially Generated Electroretinogram Components  

PubMed Central

Purpose. Processing of information through the cellular layers of the retina occurs in a serial manner. In the electroretinogram (ERG), this complicates interpretation of inner retinal changes as dysfunction may arise from “upstream” neurons or may indicate a direct loss to that neural generator. We propose an approach that addresses this issue by defining ERG gain relationships. Methods. Regression analyses between two serial ERG parameters in a control cohort of rats are used to define gain relationships. These gains are then applied to two models of retinal disease. Results. The PIIIamp to PIIamp gain is unity whereas the PIIamp to pSTRamp and PIIamp to nSTRamp gains are greater than unity, indicating “amplification” (P < 0.05). Timing relationships show amplification between PIIIit to PIIit and compression for PIIit to pSTRit and PIIit to nSTRit, (P < 0.05). Application of these gains to ?-3-deficiency indicates that all timing changes are downstream of photoreceptor changes, but a direct pSTR amplitude loss occurs (P < 0.05). Application to diabetes indicates widespread inner retinal dysfunction which cannot be attributed to outer retinal changes (P < 0.05). Conclusions. This simple approach aids in the interpretation of inner retinal ERG changes by taking into account gain characteristics found between successive ERG components of normal animals.

Emotional and coping responses to serial killings. The Gainesville murders.  

PubMed

Forensic experts have focused more on the psychological profile of a serial killer rather than on the pronounced effects on the community at large. Coping with a stressful event is thought to influence emotional states. However, little empirical understanding of this process exists. The present study examined changes in psychological factors 9 days after the occurrence of serial killings in a college community. Multivariate analyses of variance conducted on the variables of stress, anxiety, physical symptoms, and depression revealed a significant difference between the group tested after the murders and a cross-sectional cohort group. Univariate analyses revealed that the study class was significantly more depressed compared with the cohort group. The study class was also significantly more depressed compared with their own responses 1 year before the killings. For both classes, depression was significantly correlated with certain coping styles, including escape-avoidance and accept responsibility. Results have implications for certain coping behaviors (i.e., avoidant behaviors), such as that leaving the community may have been maladaptive and perhaps diverted attention from the more necessary active problem-solving behaviors (e.g., increasing security) in addition to increasing depression.

Serial position effects in recognition memory for odors.  

PubMed

Five experiments examined recognition memory for sequentially presented odors. Participants were presented with a sequence of odors and then had to identify an odor from the list in a test probe containing 2 odors. All experiments demonstrated enhanced recognition of odors presented at the start and end of a series, compared with those presented in the middle of the series when a 3-s retention interval between list termination and test was used. In Experiments 2 and 3, when a 30-s or 60-s retention interval was used, participants performed at slightly lower levels, although the serial position function was similar to that obtained with the 3-s retention interval. These results were noted with a 5-item (Experiments 1 and 4), 7-item (Experiment 2), 6-item (Experiment 3), and 4-item (Experiment 5) list of odors. As the number of test trials increased, recognition performance decreased, indicating a strong role for olfactory fatigue or interference in these procedures. A verbal suppression task, used in Experiments 4 and 5, had little influence on serial-position-based performance. PMID:10764103

Molluscan engrailed expression, serial organization, and shell evolution.  

PubMed

Whether the serial features found in some molluscs are ancestral or derived is considered controversial. Here, in situ hybridization and antibody studies show iterated engrailed-gene expression in transverse rows of ectodermal cells bounding plate field development and spicule formation in the chiton, Lepidochitona cavema, as well as in cells surrounding the valves and in the early development of the shell hinge in the clam, Transennella tantilla. Ectodermal expression of engrailed is associated with skeletogenesis across a range of bilaterian phyla, suggesting a single evolutionary origin of invertebrate skeletons. The shared ancestry of bilaterian-invertebrate skeletons may help explain the sudden appearance of shelly fossils in the Cambrian. Our interpretation departs from the consideration of canonical metameres or segments as units of evolutionary analysis. In this interpretation, the shared ancestry of engrailed-gene function in the terminal/posterior addition of serially repeated elements during development explains the iterative expression of engrailed genes in a range of metazoan body plans.

Unified formulation of dynamics for serial rigid multibody systems  

NASA Astrophysics Data System (ADS)

There has been a growing interest in the development of new and efficient algorithms for multibody dynamics in recent years. Serial rigid multibody systems form the basic subcomponents of general multibody systems, and a variety of algorithms to solve the serial chain forward dynamics problem have been proposed. In this paper, the economy of representation and analysis tools provided by the spatial operator algebra are used to clarify the inherent structure of these algorithms, to identify those that are similar, and to study the relationships among the ones that are distinct. For the purposes of this study, the algorithms are categorized into three classes: algorithms that require the explicit computation of the mass matrix, algorithms that are completely recursive in nature, and algorithms of intermediate complexity. In addition, alternative factorizations for the mass matrix and closed form expressions for its inverse are derived. These results provide a unifying perspective, within which these diverse dynamics algorithms arise naturally as a consequence of a progressive exploitation of the structure of the mass matrix.

Effects of adult aging on utilization of temporal and semantic associations during free and serial recall  

PubMed Central

Older adults show poorer performance than young adults at word list recall, especially for order information. In contrast with this temporal association deficit, older adults are generally adept at using preexisting semantic associations, when present, to aid recall. We compared the use of temporal and semantic associations in young and older adults’ word list recall following both free recall and serial recall instructions. Decomposition of serial position curves confirmed that older adults showed weakened use of temporal context in recall in relation to young adults, a difference that was amplified in serial recall. Older adults’ temporal associations were also less effective than young adults’ when correlated with serial recall performance. The differential age decrement for serial versus free recall was accompanied by a persistent influence of latent semantic associations in the older adults, even when maladaptive for serial recall.

Serial agonistic attacks by greylag goose families, Anser anser, against the same opponent  

PubMed Central

It is known from primates that alliance partners may support each other’s interests in competition with others, for example, through repeated agonistic attacks against a particular individual. We examined serial aggressive interactions between greylag goose families and other flock members. We found that repeated attacks towards the same individual were common and that up to five serial attacks by family members followed an initial attack. Family size did not affect the frequency of such serial attacks. Juvenile geese evidently benefited most from active social support through serial attacks. About 60% of the juveniles’ lost primary interactions were subsequently reversed by another family member. This may be one of the reasons why juveniles rank higher in the social hierarchy than would be expected from their age and size alone. Losses in serial attacks predominantly occurred against other, presumably higher-ranking, family geese and ganders. We propose three major functions/consequences of serial attacks. Analogous to primates, serial attacks in greylag geese may serve to reinforce a losing experience of an opponent defeated in a preceding attack. On the side of the winning family, serial attacks may reinforce the experience of winning. Both winning and losing experiences are linked with physiological consequences in higher vertebrates, affecting the future social performance of winners or losers. Finally, serial attacks may signal the agonistic potential of a family to other flock members. This is supported by heart rate data, which indicate that greylags are competent to interpret third-party relationships.

Limitations on regression analysis due to serially correlated residuals: Application to climate reconstruction from proxies

The effects of serially correlated residuals on the accuracy of linear regression are considered, and remedies are suggested. The Cochrane-Orcutt method specifically remedies the effects of serially correlated residuals and yields more accurate regression coefficients than does ordinary least squares. We illustrate the effects of serially correlated residuals, explain the application of the CO method, and evaluate the gains to be achieved in its use. We apply the method to an example from climate reconstruction, and we show that the effects of serial correlation in residuals are present and show the significantly improved result.

An integrated fiber-optic bit serializer and VCSEL (Vertical Cavity Surface Emitting Laser) driver has been constructed in radiation-hard complementary heterostructure GaAs FET (CHFET) technology. The serializer, which converts 20 parallel inputs into a high-speed serial output, consumes 60 mW at nominal supply voltage when operating at the Large Hadron Collider (LHC) word rate of 40 MHz (0.8-GB/s serial rate). The integrated driver directly drives a VCSEL and provides 10-mA switched current and 5 mA of prebias. The complete digital optical link thus consumes 90 mW.

Dilute Surfactant Methods for Carbonate Formations  

SciTech Connect

There are many fractured carbonate reservoirs in US (and the world) with light oil. Waterflooding is effective in fractured reservoirs, if the formation is water-wet. Many fractured carbonate reservoirs, however, are mixed-wet and recoveries with conventional methods are low (less than 10%). The process of using dilute anionic surfactants in alkaline solutions has been investigated in this work for oil recovery from fractured oil-wet carbonate reservoirs both experimentally and numerically. This process is a surfactant-aided gravity drainage where surfactant diffuses into the matrix, lowers IFT and contact angle, which decrease capillary pressure and increase oil relative permeability enabling gravity to drain the oil up. Anionic surfactants have been identified which at dilute concentration of 0.05 wt% and optimal salinity can lower the interfacial tension and change the wettability of the calcite surface to intermediate/water-wet condition as well or better than the cationic surfactant DTAB with a West Texas crude oil. The force of adhesion in AFM of oil-wet regions changes after anionic surfactant treatment to values similar to those of water-wet regions. The AFM topography images showed that the oil-wetting material was removed from the surface by the anionic surfactant treatment. Adsorption studies indicate that the extent of adsorption for anionic surfactants on calcite minerals decreases with increase in pH and with decrease in salinity. Surfactant adsorption can be minimized in the presence of Na{sub 2}CO{sub 3}. Laboratory-scale surfactant brine imbibition experiments give high oil recovery (20-42% OOIP in 50 days; up to 60% in 200 days) for initially oil-wet cores through wettability alteration and IFT reduction. Small (<10%) initial gas saturation does not affect significantly the rate of oil recovery in the imbibition process, but larger gas saturation decreases the oil recovery rate. As the core permeability decreases, the rate of oil recovery reduces, and this reduction can be scaled by the gravitational dimensionless time. Mechanistic simulation of core-scale surfactant brine imbibition matches the experimentally observed imbibition data. In-situ distributions observed through simulation indicate that surfactant diffusion (which depends on temperature and molecular weight) is the rate limiting step. Most of the oil is recovered through gravitational forces. Oil left behind at the end of this process is at its residual oil saturation. The capillary and Bond numbers are not large enough to affect the residual oil saturation. At the field-scale, 50% of the recoverable oil is produced in about 3 years if the fracture spacing is 1 m and 25% if 10 m, in the example simulated. Decreasing fracture spacing and height, increasing permeability, and increasing the extent of wettability alteration increase the rate of oil recovery from surfactant-aided gravity drainage. This dilute surfactant aided gravity-drainage process is relatively cheap. The chemical cost for a barrel of oil produced is expected to be less than $1.

Application of Electronic Serial Usage Statistics in a National Laboratory  

SciTech Connect

Traditional measures of library performance – walk-in visitors, number of users attending presentations, classes, number of individual subscriptions processed, etc. – do not reflect the increased activity and use of library products and services. The Hanford Technical Library is physically removed from the main campus of Pacific Northwest National Laboratory, and thus necessitates having a robust online presence in order to effectively reach and provide services to library users. Online usage statistics have become vital in convincing Laboratory management to invest funding the library at continuing or increasing levels of demand for library services. E-serial usage statistics in particular give the Hanford Technical Library a myriad of information on user behavior, research trends, collection development, and act as important analytical tools which support resource allocation analysis, reporting, and managerial decision-making. However, there are many problems with publisher and vendor supplied usage statistics and possible solutions are proposed.

The Fairchild MIL-STD-1553 Serial Multiplex Bus Tester  

NASA Astrophysics Data System (ADS)

The Fairchild Serial Multiplex Bus Tester (SMBT) is a general purpose computer controlled MIL-STD-1553 stimulus/response/analyzer. SMBT has been selected to fulfill the data bus testing requirements of the Air Force Modular Automatic Test Equipment (MATE) systems. The design is three separate devices or functions: a monitor, a bus controller, and a remote terminal simulator, which may be operated in any combination. The purpose is to integrate the Monitor, Controller, and Remote Terminal functions into a single unit. SMBT may be controlled and synchronized by a master computer performing a coordinated total checkout of a unit under test. The monitor allows a collection of 1024 word 'windows' of bus traffic and simultaneously accumulate error statistics in all bus traffic. A system self check is incorporated as an additional feature of the design. In summary, the SMBT is designed to provide necessary stimulus, response and analysis capability for MIL-STD-1553 Line Replaceable Unit (LRU) testing.

Idiopathic polyneuritis: serial studies of nerve and immune functions1  

PubMed Central

The clinical features of idiopathic polyneuritis in 22 patients admitted to the University of Kentucky Medical Center between July 1965 and June 1970 are described. Serial studies of peripheral nerve function in 12 patients followed to clinical recovery showed changes in nerve conduction velocity, distal motor latency, and/or muscle action potential amplitude. Six children and one adult, showing a change in all three parameters, exhibited a strong correlation between the degree of slowing and the shortness of their illness. Assessment of immune status, by quantitative measurement of cerebrospinal fluid immunoglobulin G(11 patients) and by the degree of lymphocyte transformation on exposure to specific brain protein and/or a homogenate of sciatic nerve (10 patients), bore no consistent relation to the severity or course of the illness. A double-blind trial of short-term, high dose adrenocorticotrophic hormone has yielded no valid evidence to date for or against the effectiveness of such therapy in this illness.

Serial analysis of gene expression (SAGE) in rat liver regeneration  

SciTech Connect

We have applied serial analysis of gene expression for studying the molecular mechanism of the rat liver regeneration in the model of 70% partial hepatectomy. We generated three SAGE libraries from a normal control liver (NL library: 52,343 tags), from a sham control operated liver (Sham library: 51,028 tags), and from a regenerating liver (PH library: 53,061 tags). By SAGE bioinformatics analysis we identified 40 induced genes and 20 repressed genes during the liver regeneration. We verified temporal expression of such genes by real time PCR during the regeneration process and we characterized 13 induced genes and 3 repressed genes. We found connective tissue growth factor transcript and protein induced very early at 4 h after PH operation before hepatocytes proliferation is triggered. Our study suggests CTGF as a growth factor signaling mediator that could be involved directly in the mechanism of liver regeneration induction.

Serially transplantable chemically induced rat islet cell tumor  

SciTech Connect

A serially transplantable, chemically induced pancreatic islet cell tumor was developed in Lewis rats. The original tumor was induced by the administration of streptozotocin and nicotinamide. It was subsequently maintained by ip or sc transplantation of tissue fragments into recipient animals. They were well encapsulated, without gross evidence of metastasis. Peroxidase immunocytochemical staining revealed a predominance of insulin-positive cells. Somatostatin-positive cells were also present and varied widely in numbers between different tumors. On electron microscopy, cells containing secretory granules, indistinguishable from nonneoplastic ..beta..-cells, were most abundant. Tumor extracts contained an average of 3260 ..mu..g insulin, 22.6 ..mu..g somatostatin, and 0.84 ..mu..g glucagon per g wet wt of tissue.

Serial and Parallel Processing in the Primate Auditory Cortex Revisited  

PubMed Central

Over a decade ago it was proposed that the primate auditory cortex is organized in a serial and parallel manner in which there is a dorsal stream processing spatial information and a ventral stream processing non-spatial information. This organization is similar to the “what”/“where” processing of the primate visual cortex. This review will examine several key studies, primarily electrophysiological, that have tested this hypothesis. We also review several human imaging studies that have attempted to define these processing streams in the human auditory cortex. While there is good evidence that spatial information is processed along a particular series of cortical areas, the support for a non-spatial processing stream is not as strong. Why this should be the case and how to better test this hypothesis is also discussed.

Efficacy comparison between simple mixed-dilution and simple mid-dilution on-line hemodiafiltration techniques: a crossover study.  

PubMed

Mid-dilution and mixed-dilution on-line hemodiafiltration (OL-HDF) techniques are innovated to overcome the limitations of two standard techniques including predilution and postdilution. Unfortunately, the head-to-head comparisons between these two novel techniques in the same study are still limited. Moreover, the original mid-dilution and mixed-dilution OL-HDF need special dialyzers and special machines. In the present study, simple mid-dilution and simple mixed-dilution OL-HDF were settled with the aim for clinical use in general hemodialysis (HD) centers. The efficacies of uremic toxins removal between both modalities were measured and compared. This prospective randomized crossover study was conducted on 12 stable HD patients undergoing simple mixed-dilution and simple mid-dilution OL-HDF techniques. HD prescriptions were similar in both techniques. The dialysis efficacies were determined by calculating small- (urea, creatinine, and phosphate) and middle-molecule (beta-2 microglobulin [?2M]) removal. Moreover, potential complications such as high transmembrane pressure (TMP) and protein loss were also observed. Simple mixed-dilution OL-HDF provided significantly greater clearances of urea, creatinine, and ?2M when compared with the simple mid-dilution OL-HDF techniques. Phosphate clearances in both techniques were comparable. In addition, TMP and dialysate albumin loss were not different. There were no intradialytic complications in both techniques. Simple mixed-dilution OL-HDF could provide greater efficacy for small- and middle-molecule clearances and acceptable potential risks, while phosphate removal is comparable. PMID:22882579

Serial position effects in recognition memory for odors: a reexamination.  

PubMed

Seven experiments examined recognition memory for sequentially presented odors. Following Reed (2000), participants were presented with a sequence of odors and then required to identify an odor from the sequence in a test probe comprising 2 odors. The pattern of results obtained by Reed (2000, although statistically marginal) demonstrated enhanced recognition for odors presented at the start (primacy) and end (recency) of the sequence: a result that we failed to replicate in any of the experiments reported here. Experiments 1 and 3 were designed to replicate Reed (2000), employing five-item and seven-item sequences, respectively, and each demonstrated significant recency, with evidence of primacy in Experiment 3 only. Experiment 2 replicated Experiment 1, with reduced interstimulus intervals, and produced a null effect of serial position. The ease with which the odors could be verbally labeled was manipulated in Experiments 4 and 5. Nameable odors produced a null effect of serial position (Experiment 4), and hard-to-name odors produced a pronounced recency effect (Experiment 5); nevertheless, overall rates of recognition were remarkably similar for the two experiments at around 70%. Articulatory suppression reduced recognition accuracy (Experiment 6), but recency was again present in the absence of primacy. Odor recognition performance was immune to the effects of an interleaved odor (Experiment 7), and, again, both primacy and recency effects were absent. There was no evidence of olfactory fatigue: Recognition accuracy improved across trials (Experiment 1). It is argued that the results of the experiments reported here are generally consistent with that body of work employing hard-to-name visual stimuli, where recency is obtained in the absence of primacy when the retention interval is short.

DILUTE SURFACTANT METHODS FOR CARBONATE FORMATIONS  

SciTech Connect

There are many carbonate reservoirs in US (and the world) with light oil and fracture pressure below its minimum miscibility pressure (or reservoir may be naturally fractured). Many carbonate reservoirs are naturally fractured. Waterflooding is effective in fractured reservoirs, if the formation is water-wet. Many fractured carbonate reservoirs, however, are mixed-wet and recoveries with conventional methods are low (less than 10%). Thermal and miscible tertiary recovery techniques are not effective in these reservoirs. Surfactant flooding (or huff-n-puff) is the only hope, yet it was developed for sandstone reservoirs in the past. The goal of this research is to evaluate dilute (hence relatively inexpensive) surfactant methods for carbonate formations and identify conditions under which they can be effective. We have conducted adsorption, phase behavior, interfacial tension (IFT) and wettability studies. Alfoterra-38 (0.05 wt%), Alfoterra-35 (0.05 wt%), SS-6656 (0.05 wt%), and DTAB (1 wt%) altered the wettability of the initially oil-wet calcite plate to an intermediate/water-wet state. Low IFT ({approx}10{sup -3} dynes/cm) is obtained with surfactants 5-166, Alfoterra-33 and Alfoterra-38. Plans for the next quarter include conducting wettability and mobilization studies.

All the carbonate surfaces (Lithographic Limestone, Marble, Dolomite and Calcite) show similar behavior with respect to wettability alteration with surfactant 4-22. Anionic surfactants (5-166, Alfoterra-33 and Alfoterra-38 and Alfoterra-68), which lower the interfacial tension with a West Texas crude oil to very low values (<10{sup -2} nM/m), have also been identified.

Addition of surfactant solution decreases the contact angle to intermediate-wet for many surfactants and water-wet for one surfactant. Addition of Na{sub 2}CO{sub 3} decreases anionic surfactant adsorption on calcite surface.

Anomalous Rayleigh scatter in dilute media  

NASA Astrophysics Data System (ADS)

Anomalous Rayleigh scatter is examined for dilute concentrations of the biomedically relevant element iodine in aqueous media including measurements with monochromatic synchrotron radiation in the vicinity of the iodine K-edge. The measurements agree with anomalous scatter-factor corrections to the form-factor approximation which has been shown to have good agreement with higher precision S-matrix calculations for small angle scatter over a wide range of energies but has not been adequately tested at the edge. Monte Carlo modelling, including the modelling of polarized Compton and Rayleigh scattered x-rays, is used to determine the relative contributions of the scatter and fluorescent components at the detector as well as the modelling of self-absorption and relative dose in the determination of detection limits. A Rayleigh scatter minimum of 28 barns/sr was observed at an energy 10 +/- 5 eV below the K-edge of iodine at a position predicted from an evaluation of the dispersion integral that includes bound-bound resonance contributions. Minimum detectable concentrations for observation of the anomalous Rayleigh scatter feature at an exposure of 10 mSv, predicted for iodine and iron, are 1 mg ml-1 and 10 mg ml-1, respectively. Upper limits to detection of the feature imposed by degradation of the signal by self-absorption are 0.021 g cm-2 and 0.0029 g cm-2 radiation lengths, respectively.

Influence of wall slip in dilute suspensions  

NASA Astrophysics Data System (ADS)

Navier's (1823) slip condition, where the tangential velocity is proportional to the shear stress, may apply at micro-scales for a viscous liquid on walls with modified surfaces, e.g. hydrophobic ones in water. Experiments by Lumma et al (2003) show the difficulties involved in measuring such a slip. At small scales, particle-wall hydrodynamic interactions are important. They are modeled here for a dilute suspension of spherical solid particles near a slip wall. Consider a translating and rotating sphere (on which the no-slip condition applies) in an ambient parabolic flow. Analytical solutions of Stokes equations for the various elementary flow fields were obtained (Feuillebois et al 2009, 2011) as series in bispherical coordinates. The coefficients in the series are solutions of an infinite linear system, which is solved by an extension of Thomas' algorithm, allowing to calculate a large number of terms. Accurate results are available for the force, torque and stresslet on a sphere, velocity of a freely moving sphere and diffusion tensor. The Aris-Taylor dispersion of Brownian particles in a shear flow near a slip wall gives a large bias in the measurement of slip (Vinogradova et al, 2009). It is calculated here from the advection-diffusion equation, using the expressions for the particle velocity and diffusion tensor near a slip wall.

Decomposition of dilute trichloroethylene by nonthermal plasma  

SciTech Connect

Decomposition performance of a dilute toxic organic compound, trichloroethylene (TCE), in air by using nonthermal plasma processing was studied extensively. The nonthermal plasma was generated by the high-frequency (2 kHz) or commercial-frequency (50 Hz) barrier discharge in a fused silica tube. Three types of reactors, bolt type, rod type (both are barrier-discharge type), and coil type (surface-discharge type), were tested. Analysis of byproducts, residual materials, and end products generated by the plasma process was performed by a gas chromatography mass spectrometer of gas chromatography. Most organic byproducts decrease with an increase of the electric discharge power, but only toxic phosgene increases with the increase of the discharge power. As a post process, NaOH solution was used to test effluent from the plasma reactor. The solution was found effective in phosgene absorption. Comparison between nonthermal plasma and UV irradiation for TCE decomposition was also made. In regard to the energy efficiency of the TCE decomposition, UV irradiation is found much better than discharge plasma.

Imbibition in an originally oil-wet 2D capillary is the fastest in the case of Alf-38 and slowest in the case of DTAB (among the surfactants studied). Force of adhesion studies and contact angle measurements show that greater wettability alteration is possible with these anionic surfactants than the cationic surfactant studied. The water imbibition rate does not increase monotonically with an increase in the surfactant concentration. A numerical model has been developed that fits the rate of imbibition. Plans for the next quarter include conducting simulation and imbibition studies.

Strengthening of solidified dilute tailings slurry  

SciTech Connect

Tailings produced during mineral processing contain up to 75% or more water and are pumped into settling ponds for disposal. They often become a pollution source due to acid generation. While tailings have been used in underground backfill, the use is very limited at present. This paper presents research results on direct solidification and strengthening of the dilute tailings slurry without dewatering. Two types of tailings were tested at water/binder ratios of up to 4.5 using a special high-water binder. Adequate strength was achieved by solidifying the tailings as is. To further improve the strength, sands and fly ash were used as reinforcement materials or partial replacement of the binder. For oil sands tailings, the 3-day strength was increased by up to 114% with 10--15% additives. For hard rock tailings, up to 30% strength gain was achieved with 15% fly ash addition, and the strength was increased by up to 36% at 10% binder replacement and no strength reduction was observed at 20--25% replacement. These results indicate that higher strength can be achieved with the proper amount of additives and that the backfill process can be simplified and the operation cost reduced.

Hubbard U Calculations for Dilute Magnetic Semiconductors  

NASA Astrophysics Data System (ADS)

Based on constrained density functional theory, we present ab initio calculations for the Hubbard U parameter of transition metal impurities in dilute magnetic semiconductors, by choosing Mn in GaN as an example. The calculations are performed by two methods: (i) the Korringa-Kohn-Rostoker (KKR) Green function method for a single Mn impurity in GaN and (ii) the Full-potentian Linear Augmented Plane-Wave (FLAPW) method for large supercell of GaN with a single Mn impurity in each cell. By changing the occupancy of the majority t2 gap state of Mn, we determine the U parameter either from the total energy differences E(N+1) and E(N-1) of the N+1 and N-1 excited states with respect to the ground state E(n), or by using the single particle energies for N+1/2 and N-1/2 occupancies (Janak's transition state model). Both methods give nearly identical results. Moreover the values calculated by the Green function technique and the supercell method agree quite well.

Low temperature photoluminescence from dilute bismides  

NASA Astrophysics Data System (ADS)

We report on photoluminescence measurements of GaAs(1-x)Bix thin films containing dilute concentration (x<=0.045%) of isoelectronic impurity Bi. At a temperature of 4 K, we observed a sharp emission line at ~1.510 eV and a series of undulations in an energy range of ~20 meV below it. We attribute the sharp line at ~1.510 eV to the recombination of excitons bound to a complex formed by unintentionally incorporated acceptor or donor atoms in the samples. Undulations observed below the sharp line at 1.510 eV are assigned to the vibronic levels of the acceptors, generated by the dynamic Jahn-Teller effect due to the coupling between the holes bound to Bi and acceptors. The sharp line at ~1.510 eV and the undulation peaks show a redshift with increasing Bi concentration due to the decrease in band gap as a result of the strong perturbation to the GaAs band structure induced by isoelectronic Bi impurities. No spectral evidence for isolated Bi forming a bound state in GaAs was seen and similar to the case of Bi in GaP, no Bi-Bi pair states were observed.

Anionic surfactant, Alfoterra-68, recovers about 40% of the oil by lower tension aided gravity-driven imbibition in the core-scale. Cationic surfactant, DTAB recovers about 35% of the oil.

Core-scale simulation results match those of the experiments. Initial capillarity-driven imbibition gives way to a final gravity-driven process. As the matrix block height increases, surfactant alters wettability to a lesser degree, or permeability decreases, oil production rate decreases. The scale-up to field scale will be further studied in the next quarter.

It is however very sensitive to oil permeability and water-oil-ratio. Less than 0.5 M Na2CO3 is needed for in situ soap generation and low adsorption; NaCl can be added to reach the necessary total salinity. The simulation result matches the laboratory imbibition experimental data. Small fracture spacing and high permeability would be needed for high rate of recovery.

Research over the last 25 years has demonstrated that animals are able to organize sequences in memory and retrieve ordered sequences without language. Qualitative differences have been found between the serial organization of behavior in pigeons and monkeys. Here the authors test serial ordering abilities in ring-tailed lemurs, a strepsirrhine primate whose ancestral lineage diverged from that of monkeys, apes,

Serial data fusion using space-filling curves in wireless sensor networks  

Microsoft Academic Search

This paper considers serial fusion as a mechanism for collaborative signal detection. The advantage of this technique is that it can use only the sensor observations that are really necessary for signal detection and thus can be very communication efficient. We develop the signal processing mechanisms for serial fusion based on simple models. We also develop a space-filling curve-based routing

An econometric model of serial correlation and illiquidity in hedge fund returns  

Microsoft Academic Search

The returns to hedge funds and other alternative investments are often highly serially correlated. In this paper, we explore several sources of such serial correlation and show that the most likely explanation is illiquidity exposure and smoothed returns. We propose an econometric model of return smoothing and develop estimators for the smoothing profile as well as a smoothing-adjusted Sharpe ratio.

Female serial murderers: directions for future research on a hidden population.  

PubMed

This comprehensive overview on a sample of 65 cases (134 total offenders, including some partnered teams of more than 2 offenders) provides information on female serial murderers who either work in a mixed-sex offending group or alone. These female serial homicide offenders have a distinct set of offender-victim characteristics, including specific victim preferences, methods, and motivations: Partnered serial homicide offenders are more likely to target adult strangers and dispatch them using a combination of methods, whereas solo female serial murderers are most likely to target adult family members and murder them with poison. These patterns have the potential to add to our understanding of the possible similarities and differences of serial homicide cases by building on established offender characteristics. Convictions and sentences for the offenders are included and areas of future research and implications for treatment with this sample are also explored. PMID:19910510

The case of Jeffrey Dahmer: sexual serial homicide from a neuropsychiatric developmental perspective.  

PubMed

Sexual serial homicidal behavior has received considerable attention during the last three decades. Substantial progress has been made in the development of methods aimed at identifying and apprehending individuals who exhibit these behaviors. In spite of these advances, the origins of sexual serial killing behavior remain for the most part unknown. In this article we propose a biopsychosocial psychiatric model for understanding the origins of sexual serial homicidal behavior from both neuropsychiatric and developmental perspectives, using the case of convicted serial killer Jeffrey Dahmer as the focal point. We propose that his homicidal behavior was intrinsically associated with autistic spectrum psychopathology, specifically Asperger's disorder. The relationship of Asperger's disorder to other psychopathology and to his homicidal behavior is explored. We discuss potential implications of the proposed model for the future study of the causes of sexual serial homicidal crime. PMID:12455663

Binding Serial Order to Representations in Working Memory: a Spatial/Verbal Dissociation  

PubMed Central

Verbal information is coded naturally as ordered representations in working memory (WM). However, this may not be true for spatial information. Accordingly, we used memory-span tasks to test the hypothesis that serial order is more readily bound to verbal than to spatial representations. Removing serial-order requirements improved performance more for spatial locations than for digits. Furthermore, serial order was freely reproduced twice as frequently for digits as for locations. When participants reordered spatial sequences, they minimized the mean distance between items. Participants also failed to detect changes in serial order more frequently for spatial than for verbal sequences. These results provide converging evidence for a dissociation in the binding of serial order to spatial vs. verbal representations. There may be separable domain-specific control processes responsible for this binding. Alternatively, there may be fundamental differences in how effectively temporal information can be bound to different types of stimulus features in WM.

Psychological profiling of offender characteristics from crime behaviors in serial rape offences.  

PubMed

Criminal psychological profiling has progressively been incorporated into police procedures despite a dearth of empirical research. Indeed, in the study of serial violent crimes for the purpose of psychological profiling, very few original, quantitative, academically reviewed studies actually exist. This article reports on the analysis of 62 incidents of serial sexual assault. The statistical procedure of multidimensional scaling was employed in the analysis of this data, which in turn produced a five-cluster model of serial rapist behavior. First, a central cluster of behaviors were identified that represent common behaviors to all patterns of serial rape. Second, four distinct outlying patterns were identified as demonstrating distinct offence styles, these being assigned the following descriptive labels brutality, intercourse, chaotic, and ritual. Furthermore, analysis of these patterns also identified distinct offender characteristics that allow for the use of empirically robust offender profiles in future serial rape investigations.

Stability of the replica symmetric solution in diluted perceptron learning  

NASA Astrophysics Data System (ADS)

We study the role played by dilution in the average behavior of a perceptron model with continuous coupling with the replica method. We analyze the stability of the replica symmetric solution as a function of the dilution field for the generalization and memorization problems. Thanks to a Gardner-like stability analysis we show that at any fixed ratio ? between the number of patterns M and the dimension N of the perceptron (? = M/N), there exists a critical dilution field hc above which the replica symmetric ansatz becomes unstable.

Effect of dilution on carboxymethylcellulase and xylanase assays  

SciTech Connect

It has been demonstrated that the dilution of samples prior to the carboxymethylcellulase and xylanase assays causes serious discrepancies in the numerical values obtained for the enzyme activities. Even when the sample is assayed with the identical procedure, one could obtain different numerical values of the enzyme activity U depending on how much this sample has been diluted before the enzyme assay. Two crude commercial cellulase samples of Aspergillus niger and Trichoderma viride as well as the culture filtrate of our newly isolated acidophilic fungus have been used for the demonstration. An empirical method for reporting the cellulolytic activity by taking into account this dilution effect is proposed.

Retroviral sequences located within an intron of the dilute gene alter dilute expression in a tissue-specific manner.  

PubMed Central

The murine dilute coat color locus encodes an unconventional myosin heavy chain that is thought to be required for the elaboration or maintenance of dendrites or organelle transport in melanocytes and neurons. In previous studies we showed that the d mutation carried by many inbred strains of mice (now referred to as dilute viral, dv), is caused by the integration of an ecotropic murine leukemia virus (Emv-3) into the dilute gene and that phenotypic revertants of dv (termed d+) result from viral excision; a solo viral long terminal repeat (LTR) is all that remains in revertant DNA. In the studies described here we show that Emv-3 sequences are located within an intron of the dilute gene in a region of the C-terminal tail that is differentially spliced. We also show that these Emv-3 sequences result in the production of shortened and abnormally spliced dilute transcripts and that the level of this effect varies among tissues. This tissue-specific effect on dilute expression likely accounts for the absence of neurological abnormalities observed in dv mice. Surprisingly, we also found that the solo viral LTR present in revertant d+ DNA produces a tissue-specific effect on dilute expression, although this effect is less dramatic than with the full-length provirus and produces no obvious mutant phenotype. These findings have important implications for understanding the effects of viral sequences on mammalian gene expression. Images

Dilute Oxygen Combustion Phase IV Final Report  

SciTech Connect

Novel furnace designs based on Dilute Oxygen Combustion (DOC) technology were developed under subcontract by Techint Technologies, Coraopolis, PA, to fully exploit the energy and environmental capabilities of DOC technology and to provide a competitive offering for new furnace construction opportunities. Capital cost, fuel, oxygen and utility costs, NOx emissions, oxide scaling performance, and maintenance requirements were compared for five DOC-based designs and three conventional air5-fired designs using a 10-year net present value calculation. A furnace direct completely with DOC burners offers low capital cost, low fuel rate, and minimal NOx emissions. However, these benefits do not offset the cost of oxygen and a full DOC-fired furnace is projected to cost $1.30 per ton more to operate than a conventional air-fired furnace. The incremental cost of the improved NOx performance is roughly $6/lb NOx, compared with an estimated $3/lb. NOx for equ8pping a conventional furnace with selective catalytic reduction (SCCR) technology. A furnace fired with DOC burners in the heating zone and ambient temperature (cold) air-fired burners in the soak zone offers low capital cost with less oxygen consumption. However, the improvement in fuel rate is not as great as the full DOC-fired design, and the DOC-cold soak design is also projected to cost $1.30 per ton more to operate than a conventional air-fired furnace. The NOx improvement with the DOC-cold soak design is also not as great as the full DOC fired design, and the incremental cost of the improved NOx performance is nearly $9/lb NOx. These results indicate that a DOC-based furnace design will not be generally competitive with conventional technology for new furnace construction under current market conditions. Fuel prices of $7/MMBtu or oxygen prices of $23/ton are needed to make the DOC furnace economics favorable. Niche applications may exist, particularly where access to capital is limited or floor space limitations are critical. DOC technology will continue to have a highly competitive role in retrofit applications requiring increases in furnace productivity.

Predictability of Various Serial Subtractions on Global Deterioration Scale According to Education Level  

PubMed Central

Background The serial 100-7s subtraction, an item on the Mini-Mental State Examination (MMSE), is well known for being difficult for uneducated people. Therefore, we investigated into alternative serial subtractions for serial 100-7s subtraction in uneducated people. Methods One hundred sixty-nine subjects were enrolled by neurologic or neuropsychiatric out-patient clinics in 4 university medical centers. The subjects were divided into two groups: an uneducated group and an educated group (at least primary schooling) by questionnaire. We investigated the correlation between incorrect number of serial subtractions and Global Deterioration Scale (GDS) score in both groups and undertook receiver operating characteristic (ROC) curve analysis. MMSE including serial 40-4s subtraction, serial 20-2s subtraction, and serial 10-1s subtraction instead of serial 100-7s subtraction were arbitrally named MMSE4, MMSE2, and MMSE1. Results In the educated group, serial 100-7s subtraction showed the highest correlation with GDS score (correlation coefficient, 0.465; P < 0.001). In the uneducated group, serial 40-4s subtraction showed the highest correlation with GDS score (correlation coefficient, 0.608; P < 0.001), and serial 100-7s indicated the lowest correlation (correlation coefficient, 0.378; P = 0.023). In ROC curve analysis for MMSE, MMSE4, MMSE2, and MMSE1 to assess the presence of dementia (GDS score ? 3) in uneducated subjects, the area under the curve (AUC) was 0.648, 0.770, 0.758, and 0.711, respectively, and in educated subjects, AUC for MMSE, MMSE4, MMSE2, and MMSE1 was 0.729, 0.719, 0.716, and 0.714, respectively. Conclusion Out of MMSE items, serial 100-7s is adequate in the educated elderly, but may be less adequate in the uneducated elderly. Serial 40-4s seems to be more appropriate for MMSE in the uneducated elderly.

Serial postmortem abdominal radiographic findings in canine cadavers.  

PubMed

Postmortem radiographic examinations of animals are often performed in judicial investigation to rule out gunshot and fractures due to cruelty or illegal hunting or poaching activities. Literature describing postmortem changes seen on radiographs of animals is rarely available. Serial abdominal radiography of 6 recently euthanized dogs were performed in an interval of 8h at a tropical ambient temperature of 22-33 degrees C. Severe decomposition of the cadavers prevented the study to be performed beyond 24h. Gradual increment of gas accumulation in the gastrointestinal tract, liver, spleen, kidney and blood vessels were observed. Increased amount of gas in the gastrointestinal tract was detected as early as 8h post-euthanasia and continuously increased throughout the study. Gas was seen in the portal vein and caudal vena cava of all cadavers at 16h post-euthanasia. The presence of gas in the aorta occurred at a later stage. Tubular branching gas pattern in the liver and spleen was first observed and progressed to vesicular gas pattern due to tissue decomposition. This study showed that abdominal radiographic postmortem changes occurred most rapidly between 8 and 16h post-euthanasia at the ambient temperature of 22-33 degrees C. PMID:19716666

Disclosed is a solid oxide fuel cell for electrochemically combining fuel and oxidant for generating galvanic output. The cell core has an array of cell segments electrically serially connected in the flow direction, each segment consisting of electrolyte walls and interconnect that are substantially devoid of any composite inert materials for support. Instead, the core is monolithic, where each electrolyte wall consists of thin layers of cathode and anode materials sandwiching a thin layer of electrolyte material therebetween. Means direct the fuel to the anode-exposed core passageways and means direct the oxidant to the cathode-exposed core passageways; and means also direct the galvanic output to an exterior circuit. Each layer of the electrolyte composite materials is of the order of 0.002 to 0.01 cm thick; and each layer of the cathode and anode materials is of the order of 0.002 to 0.05 cm thick. Between 2 and 50 cell segments may be connected in series.

Serial exercise gated radionuclide ventriculograms (RVG) in monitoring doxorubicin cardiotoxicity  

SciTech Connect

The resting RVG (Radionuclide Ventriculograms) are demonstrated to be an effective monitor of the cardiotoxicity of doxorubicin. The exercise RVG has not been as well studied to see if it yields additional information or detects toxicity effects earlier. Sixteen patients receiving doxorubicin for chemotherapy had 2-6 serial exercise studies with intervals between studies of 1 month to 15 months. The patients exercised varying amounts with cardiac work indicated by their double products (HR x Sys. BP). Although all patients started with a normal resting LVEF (>50%), 5 of the 16 did not have a normal response (greater than or equal to5% increase in LVEF) with initial exercise study. Of the 11 patients with an initially normal response to exercise, on at least one subsequent study, 3 had an abnormal response to exercise. On a later follow up study 1 of these 3 patients again had a normal response to exercise. Six of these 11 patients had had RVG evidence of cardiotoxicity. Four of these 6 patients had continually normal exercise responses, while 2 of these 5 patients had had an abnormal exercise response. An initial exercise RVG may be reasonable to detect unsuspected CAD in cancer victims. These patients are reported to be more sensitive to the toxic effects of doxorubicin. Follow up exercise RVGs do not contribute useful information, do not predict cardiotoxicity, and may be misleading.

[Serial changes in lung injury produced by preformed immune complexes].  

PubMed

A previous study demonstrated increased levels of C5a des Arg and increased numbers of polymorphonuclear cells (PMNs) in bronchoalveolar lavage (BAL) fluids of acutely ill patients with summer type hypersensitivity pneumonitis (HP), suggesting the role of immune complexes (IC) in the early stage of HP. The present study was undertaken to compare the BAL findings in patients with acute HP and in animals which were injected intratracheally with preformed IC and to determine the correlation between the sequential BAL findings and the serial histology in animals. The results indicated that total cells recovered by BAL increased up to 24 hours. However, the most striking observation was that the increased number and percentage of PMNs in BAL cells shortly after the intratracheal injection, which the number of macrophages in BAL cells tended to be high, the increase was not statistically significant. Histological examinations revealed peribronchial and intraalveolar infiltration with PMNs at the early stage when intraalveolar infiltration were predominant, and the latest lesions consisted of infiltration with mononuclear cells in the alveolar walls. Furthermore, the cellular findings of BAL cells reflected the histological findings in involved lungs. The present study demonstrated that the sequential BAL changes of acutely ill patients with HP were similar to those of IC-injected animals, suggesting the possibility that IC formed in the airways is involved in the early stage of HP.

Serial Assessment of Physiological Evaluation Indices for Repetitive Mental Workload  

NASA Astrophysics Data System (ADS)

The objective of this study is to evaluate the effect of daily repetitive mental workload on physiological indices. Especially, the index derived from the nasal skin temperature(NST) measured by the infrared thermography was focused. The NST was the physiological index representing the sympathetic nervous system activity. The NST declines with the sympathetic nervous system's activation. The mental workload causes sympathetic nervous system's activation, so the mental workload can be measured by NST as a declining temperature. We have found that the relationship between the amount of mental workload and the NST declining under time pressure, even more complex stimuli. However, there's no study on evaluating the NST measured for the repetitive mental workload for certain period of time. In this paper, the NST and other physiological indices, which were Fm? wave component of Electroencephalograms(EEG) and high frequency component(HF) of R-wave interval time series of Electrocardiograms(ECG) were serially measured and evaluated on repetitive mental workload. Significant difference was found between those NST indices in each experiment by paired t-test. A stability of NST as an evaluation index for MWL was proved.

Serial Cardiac Magnetic Resonance Imaging of Injected Mesenchymal Stem Cells  

PubMed Central

Background Delivery and tracking of endomyocardial stem cells are limited by the inability to image transplanted cells noninvasively in the beating heart. We hypothesized that mesenchymal stem cells (MSCs) could be labeled with a iron fluorophore particle (IFP) to provide MRI contrast in vivo to assess immediate and long-term localization. Methods and Results MSCs were isolated from swine. Short-term incubation of MSCs with IFP resulted in dose-dependent and efficient labeling. Labeled cells remained viable for multiple passages and retained in vitro proliferation and differentiation capacity. Labeled MSCs (104 to 106 cells/150 ?L) were injected percutaneously into normal and freshly infarcted myocardium in swine. One, 3, and 1 animals underwent serial cardiac MRI (1.5T) for 4, 8, and 21 days, respectively. MRI contrast properties were measured both in vivo and in vitro for cells embedded in agar. Injection sites containing as few as 105 MSCs could be detected and contained intact IFP-bearing MSCs on histology. Conclusions IFP labeling of MSCs imparts useful MRI contrast, enabling ready detection in the beating heart on a conventional cardiac MR scanner after transplantation into normal and infarcted myocardium. The dual-labeled MSCs can be identified at locations corresponding to injection sites, both ex vivo using fluorescence microscopy and in vivo using susceptibility contrast on MRI. This technology may permit effective in vivo study of stem cell retention, engraftment, and migration.

Phonological and semantic strategies in immediate serial recall.  

PubMed

It has been suggested that certain theoretically important anomalous results in the area of verbal short-term memory could be attributable to differences in strategy. However there are relatively few studies that investigate strategy directly. We describe four experiments, each involving the immediate serial recall of word sequences under baseline control conditions, or preceded by instruction to use a phonological or semantic strategy. Two experiments varied phonological similarity at a presentation rate of one item every 1 or 2 seconds. Both the control and the phonologically instructed group showed clear effects of similarity at both presentation rates, whereas these were largely absent under semantic encoding conditions. Two further experiments manipulated word length at the same two rates. The phonologically instructed groups showed clear effects at both rates, the control group showed a clear effect at the rapid rate which diminished with the slower presentation, while the semantically instructed group showed a relatively weak effect at the rate of one item per second, and a significant reverse effect with slower presentation. The latter finding is interpreted in terms of fortuitous differences in inter-item rated associability between the two otherwise matched word pools, reinforcing our conclusion that the semantically instructed group were indeed encoding semantically. Implications for controlling strategy by instruction are discussed. PMID:18432478

Salience modulation in serial preexposure: implications for perceptual learning.  

PubMed

In three experiments rats were given serial preexposure to two flavor stimuli. In Experiment 1, some animals were given exposure to AX followed by the presentation of BX, a forward schedule; the others were given backward preexposure (BX?AX). Conditioning and test trials with the A element showed that salience or effectiveness of A was better protected in the forward than in the backward condition. Experiments 2 and 3 assessed the relevance of this salience modulation mechanism for perceptual learning. In these experiments, generalization of a conditioned aversion from AX to BX was reduced in the forward (but not in the backward) condition only after prolonged exposure, indicating that the establishment of an inhibitory link from B to A is required for successful discrimination. However, generalization to a novel compound stimulus, NX, was reduced in the forward group both after short and long preexposure, suggesting the existence of salience modulation processes that work in parallel with associative inhibition. These results seem to support the existence of a salience modulation mechanism that seems to be beyond the scope of current theories of perceptual learning. PMID:22229588

A rare case of serial killing by poisoning.  

PubMed

A case of serial killing by poisoning by a 59-year-old practical nurse is discussed. Following a report by an emergency-room doctor of an attempted murder, police performed an investigation into all deaths of patients in the nurse's care. Earlier, a medico-legal cause-of-death investigation had been performed on two of these cadavers, but in the other three cases the death certificate had been issued after a medical investigation only. In two of these latter cases, the body had been cremated, but fixed histological samples taken at medical autopsy were available, while in one case the person had died recently and the body was thereafter exhumed and autopsied. All of the suspected victims were older people who required nursing, and the nurse's course of action was consistent in all cases. In the absence of ordinary post-mortem toxicology samples in the medical cases, extraordinary evidence - paraffin-embedded liver tissue samples originally taken for histology at autopsy - was successfully recovered in two cases and analyzed for drugs. In all five cases, drugs not prescribed to the patient were detected, including digoxin, dixyrazine, citalopram, venlafaxine, and benzodiazepines (diazepam, chlordiazepoxide, temazepam, and oxazepam). The nurse was eventually found guilty of five murders by poisoning, five attempted murders, and three aggravated assaults. The nurse was sentenced to life imprisonment.

Serial Foodborne Norovirus Outbreaks Associated with Multiple Genotypes  

PubMed Central

Noroviruses (NoV) have been recognized as an important pathogen associated with acute gastroenteritis worldwide during the past three decades. In the spring of 2012, a series of foodborne outbreaks in tourist groups were reported to Xiamen Center for Disease Control and Prevention, Xiamen, Fujian province, China. Among a total of 268 tourists in 7 groups, the prevalence rate of acute gastroenteritis was 16.0% (43/268). Twenty-three feces or anal swabs were collected for laboratory tests of causative agents, no bacterial pathogen was identified, while 22 of them were positive for NoV RNA. In addition, thirteen NoV fragments were recovered from positive specimens and sequenced, belonging to five genotypes such as GI.3, GI.4, GII.4, GII.6, and GII.14, respectively. However, NoV fragments obtained from locally infected patients showed distinct genotypes. Therefore, epidemiological investigation and laboratory analyses demonstrated that the serial foodborne NoV outbreaks in tourists were co-infection of multiple genotypes induced acute gastroenteritis linked to a restaurant.

Serial monogamy and sex ratio bias in Nazca boobies.  

PubMed

Biased operational sex ratios (OSRs) can drive sexual selection on members of the over-represented sex via competition for mates, causing higher variance and skew in reproductive success (RS) among them if an individual's quality is a persistent characteristic. Alternatively, costs of reproduction may degrade breeding performance, creating the opportunity for members of the limiting sex to switch mates adaptively, effectively homogenizing variance and skew in RS among the sex in excess. We tested these two contrasting models in a male-biased population of the Nazca booby (Sula granti) with demonstrated costs of reproduction with data on total RS over a 14-year period. Variances and skews in RS were similar, and males changed from breeder to non-breeder more frequently than females. Under the persistent individual quality model, females should mate only with high quality males, and non-breeding males should seldom enter the breeding pool, yet 45% of non-breeding males (re)entered the breeding pool each year on average. Many Nazca booby females apparently exchange a depleted male for a new mate from the pool of current non-breeder males. Our evidence linking serial monogamy to costs of reproduction is novel and suggests selection on female mating preferences based on an interaction between at least two life-history components (OSR and reproductive effort).

Ultrastructural reconstruction of Taenia ovis oncospheres from serial sections.  

PubMed

The cellular organisation of Taenia ovis oncospheres is interpreted from ultrathin serial sections and transmission electron microscopy following high pressure freezing and freeze-substitution. The surface of a hatched, non-activated T. ovis oncosphere is covered by an oncospheral membrane below which is the tegument bearing microvilli. The basal lamina of the tegument is underlain by broad bands of peripheral somatic musculature. Three pairs of hooks and associated muscles are present in the somatophoric third of the oncosphere. Approximately 19 cells of seven different types were identified which include: (i) a quadri-nucleated syncytium of penetration gland type 1 containing two lateral pairs of cell bodies interconnected by narrow cytoplasmic bridges (PG1); (ii) a quadri-nucleated syncytium of penetration gland type 2 (PG2); (iii) a single-nucleated median mesophoric gland cell; (iv) 10 somatic cells; (v) two germinative cells; (vi) two nerve cells; and (vii) a pair of median somatophoric cells. This study provides a clear understanding of the morphology of T. ovis oncospheres and forms the basis for further investigations into the biology of taeniid oncospheres. PMID:20478311

Visible Korean human: another trial for making serially sectioned images  

NASA Astrophysics Data System (ADS)

The Visible Korean Human dataset is currently being made. The performance period for the experiment is March 2000- August 2005. The complete MR and CT images of the Korean cadaver are acquired. The cadaver is serially sectioned (interval: 0.2 mm) and inputted into the personal computer to make anatomical images (pixel size: 0.2 mm) without missing images. Anatomical structures in the anatomical images are segmented. The Visible Korean Human dataset is expected to be more beneficial than the Visible Human Project dataset in many ways. First, the Korean images will be more helpful in diagnosing and treating patients belonging to the Oriental race. Second, the complete MR and CT images will be more helpful in studying MR and CT images. Third, the anatomical images without missing images will be more beneficial by making complete 3D images. Fourth, the anatomical images with thin interval (0.2 mm) and small pixel size (0.2 mm) will show small anatomical structures. Fifth, the additional segmented images will make 3D images and virtual dissection software easily.

Serial analysis of gene expression (SAGE): application in cancer research.  

PubMed

Serial analysis of gene expression (SAGE) is a powerful tool that allows digital analysis of overall gene expression patterns. SAGE provides quantitative and comprehensive expression profiling in a given cell population. Because SAGE does not require a preexisting clone, it can be used to identify and quantitate new as well as known genes. It works by isolating short fragments of genetic information from the genes expressed in the cell being studied. These short sequences, called SAGE tags, are linked together for efficient sequencing. SAGE is particularly well suited for organisms whose genome is not completely sequenced, because it does not require a hybridization probe for each transcript and allows new genes to be discovered. New modifications of SAGE now permit the analysis of gene expression in cell sub-populations or micro-anatomic structures, providing access to unexplored transcriptomes of normal and disease biology. Data derived using the SAGE technology have been used to identify tumor markers for a variety of cancers, including gastrointestinal cancer, lung and thyroid cancer, breast and ovarian cancer, neuroblastoma and glioblastoma, prostate cancer, and renal cell carcinoma. In this review we present an outline of the method and updated information on the applications of SAGE technology to various cancers. PMID:15173683

Erosive events in dilute pyroclastic density currents  

NASA Astrophysics Data System (ADS)

Our understanding of the dynamics of pyroclastic density currents (PDCs) is largely based on the study of their deposits. However, sedimentological structures reflect only the low energy, depositional phases of a flow. To enlarge the source of information on PDC behaviour, we provided wind-tunnel experiments to measure the minimal velocity necessary to erode dry, volcanic ash. Our results permit to link erosive surfaces that are often found in PDC deposits to the minimum velocity that must have acted to produce them. We apply the method to field examples and discuss the occurrence of hydraulic-jumps in dilute PDCs. We measured the threshold of surface friction-velocity for erosion of two types of volcanic ash: 1) a mixture of fragments of vesiculated scoria containing also lithics and crystals and 2) pumice clasts from the Plinian Laacher See eruption. Both were sampled in quarries from the East Eifel volcanic field (Germany). For each type, we measured the threshold for particles from 63 ?m to 2 mm in 1 phi-size steps. Static threshold friction-velocities have been measured experimentally in an open, 6 m-long wind-tunnel at Aarhus University. In order to quickly guarantee the downwind equilibrium-dynamics of the saltating sand-surface, we produced roughness-carpets upstream of the study area. The roughness-carpets consist of particles of the measured sample fixed onto the bed in order to create an appropriate static roughness. The measuring section (1 m in length) is located at the downwind end of the wind-tunnel and covered with 10 mm of sample. The wind velocity in the wind-tunnel was progressively increased until a small but continuous number of grains left the surface. This wind velocity was taken as the threshold, and the associated surface friction-velocity was deduced by calibration from wind-profiles data taken over the fixed surface of material of the same characteristics. We apply our results to sedimentary features found in natural deposits and usually interpreted as "chute and pool" structures. These are characterized by erosional events producing a steep side facing the flow, and lensoidal layers deposited on the stoss face of the un-eroded, remaining strata. Our experimental results allow for quantifying the minimum current-velocity required for the observed erosion. Based on this, we discuss the interpretation of such erosional features as "chute and pool" structures, which are the sedimentary record of hydraulic-jumps. There is no clear evidence of the presence of internal hydraulic-jumps in the sedimentary record of PDCs. Moreover, such flows can decelerate drastically and eventually stop without leaving the supercritical flow regime due to their highly depositional nature. Accordingly, they would not experience a hydraulic-jump.

A comparative analysis of serial ordering in ring-tailed lemurs (Lemur catta).  

PubMed

Research over the last 25 years has demonstrated that animals are able to organize sequences in memory and retrieve ordered sequences without language. Qualitative differences have been found between the serial organization of behavior in pigeons and monkeys. Here the authors test serial ordering abilities in ring-tailed lemurs, a strepsirrhine primate whose ancestral lineage diverged from that of monkeys, apes, and humans approximately 63 million years ago. Lemurs' accuracy and response times were similar to monkeys, thus suggesting that they may share mechanisms for serial organization that dates to a common primate ancestor. PMID:18085919

We were involved as forensic experts in the case of the serial killer Jeffrey Dahmer. We discuss the scene and victim autopsy findings, with a brief consideration of the basic emotion of hostility. These findings support the thesis that at the basis of this serial killer's behavior were primary unconscious feelings of hate that he had channeled into a sadistic programmed destruction of 17 young men. The interview of the serial killer, the photographic scene documentation, and the autopsy findings stress the ambivalent homosexuality of the killer, his sexual sadism, his obsessive fetishism, and his possible cannibalism and necrophilia.

Dominance of the odometer over serial landmark learning in honeybee navigation  

NASA Astrophysics Data System (ADS)

Honeybees use their visual flow field to measure flight distance. It has been suggested that the experience of serial landmarks encountered on the flight toward a feeding place contributes to distance estimation. Here, we address this question by tracing the flight paths of individual bees with a harmonic radar system. Bees were trained along an array of three landmarks (tents), and the distance between these landmarks was either increased or decreased under two test conditions. We find that absolute distance estimation dominates the search for the feeding place, but serial position effects are also found. In the latter case, bees search only or additionally at locations determined by serial experience of the landmarks.

Effects of dietary dilution source and dilution level on feather damage, performance, behavior, and litter condition in pullets.  

PubMed

An experiment was conducted to investigate the effects of dietary dilution sources and levels on feather damage, performance, feeding behavior, and litter condition in rearing pullets. It was hypothesized that dietary dilution increases feeding-related behavior and improves feather condition, particularly if insoluble nonstarch polysaccharides are used as the dilution source. In total, 864 Lohmann Brown 1-d-old non-beak-trimmed pullets were used until 18 wk of age. Four dietary treatments, a control diet without any dilution (R_0%), 7.5% diluted diet with sunflower seed extract/oat hulls (R_7.5%), 15% diluted diet with sunflower seed extract (R_15%_S), and 15% diluted diet with oat hulls (R_15%_O), with 6 replicates (1 replicate is a pen with 36 pullets) per treatment were used. On 4-wk intervals, behavioral parameters, including eating time, feather pecking, feather condition, and general behavior were evaluated. Pullets fed the control diet showed increased feather, comb, and wire pecking compared with pullets fed diluted diets. The level of feather damage decreased with increasing dietary dilution level. Pullets receiving R_15%_S and R_15%_O showed more feeding-related behavior than the pullets on R_7.5% and R_0%. Oat hulls were more effective in preventing feather damage than sunflower seed extract. Pullets did not fully compensate their feed intake if fed a dietary dilution, resulting in a proportionally reduced available ME intake. The R_15%_O pullets had 2.9% lower average BW gain compared with those fed R_0%. Average eating duration increased by 12.8, 33.2, and 42.1% in R_7.5%, R_15%_S, and R_15%_O fed pullets, respectively, compared with R_0%, whereas eating rate [feed intake (g)/pullet per eating min] was decreased in R_15%_S and R_15%_O pullets. Relative weights of empty gizzards were 3.95, 10.30, and 62.72% greater in R_7.5%, R_15%_S, and R_15%_O pullets compared with pullets fed R_0%. It was concluded that dietary dilution affected time budgets of the pullets, as shown by more feeding-related behavior, resulting in less feather pecking behavior. Based on our results, application of this feeding strategy could improve production and welfare in pullets. PMID:23436509

Motor Lateralization is characterized by a serial hybrid control scheme  

PubMed Central

Our previous studies of limb coordination in healthy right and left-handers led to the development of a theoretical model of motor lateralization, dynamic dominance, which was recently supported by studies in patients with unilateral stroke (For Review, see Sainburg, 2010: Lateralization of Goal-Directed Movements, in Human Kinetics). One of our most robust findings was on single joint movements in young healthy subjects (Sainburg and Schaefer, 2004: Interlimb differences in control of movement extent). In this study, subjects made elbow joint reaching movements toward 4 targets of different amplitudes with each arm. Whereas, both arms achieved equivalent task performance, each did so through different strategies. The dominant arm strategy scaled peak acceleration with peak velocity and movement extent, while the nondominant strategy adjusted acceleration duration to achieve the different velocities and distances. We now propose that these observed interlimb differences can be explained using a serial hybrid controller, in which movements are initiated using predictive control and terminated using impedance control. Further, we propose that the two arms should differ in the relative time that control switches from the predictive to the impedance mechanisms. We present a mathematical formulation of our hybrid controller and then test the plausibility of this control paradigm by investigating how well our model can explain interlimb differences in experimental data. Our findings confirm that the model predicts early shifts between controllers for left arm movements, which rely on impedance control mechanisms, and late shifts for right arm movements, which rely on predictive control mechanisms. This is the first computational model of motor lateralization, and is consistent with our theoretical model that emerged from empirical findings. It represents a first step in consolidating our theoretical understanding of motor lateralization into an operational model of control.

Serial measurement of portal hemodynamics after partial portal decompression.  

PubMed

In a serial analysis of splanchnic hemodynamics, we compared partial with total portal decompression in 16 alcoholic cirrhotic patients who underwent portacaval shunts for variceal hemorrhage. Partial decompression was achieved with 8 or 10 mm polytetrafluorethylene portacaval H grafts and aggressive collateral ligation. Total decompression was achieved with larger diameter H grafts (12 or 14 mm). Early and follow-up (mean interval, 18 months) postoperative studies of portal hemodynamics included: direct measurement of shunt gradients, scintigraphic quantitation of portal and mesenteric flow distribution to the liver, and a portal and splenic collateral scoring system developed from standardized splenic venography. Partial portal decompression reduced portal pressure by 43% +/- 8% compared with 81% +/- 5% after total decompression (p less than 0.01). Scintigraphy demonstrated that partial decompression provided a greater fraction of portal flow to the liver than did total decompression (57% +/- 9% versus 2% +/- 1% intrahepatic radioactivity) and mesenteric flow distribution (14.5% +/- 5.4% versus 1.2% +/- 0.7%). Only one patient with partial decompression had a significant loss of portal perfusion during the interval studies. Significantly more residual collaterals were visualized in patients with partial decompression than in those with total decompression, and interval studies showed no significant changes from early studies. We conclude that partial decompression maintains higher portal pressures, more residual collaterals, and a greater fraction of portal and mesenteric flow to the liver than does total decompression. A modest but uniform reduction of portal pressure minimizes stimulus for new collateral formation and further shunting of portal flow. PMID:3726761

[The monitoring of gynecological radiotherapy using serial tumor marker determinations].  

PubMed

In 149 collum and 45 corpus carcinomas tumor marker concentrations in serum have been measured before, during and sex to eight weeks after termination of radiotherapy. For the collum carcinomas (average of FIGO I to IV) the sensitivity of CEA was found to be 51%, SCC 67%, CEA +SCC 80%. In corpus carcinomas CEA had low sensitivity and could not readily be used for therapy monitoring. However, in a number of cases CA125 was a good substitute. Six to eight weeks after termination of radiotherapy the average tumor marker levels have been declined by comparison with the pretherapeutic values (100%): For the collum carcinoma CEA dropped to 39%, SCC to 57%; for the corpus carcinoma CEA to 72%, CA 125 to 81%. The highest diagnostic information was gained by comparison of post-therapeutical tumor-marker levels with cut off values obtained from healthy women of the same age group. After treatment in 29 of 106 collum carcinomas CEA and or SCC levels did still exceed these cut off values. In eleven cases this marker elevation was due to paraaortic lymph node metastases, in seven cases a local tumor residue was discovered and in six cases general metastases. In corpus carcinomas the main reason for post-therapeutic elevated CA125 values also were paraaortic lymph node metastases. Thus, the use of serial tumor marker determination for control of gynecological radiotherapy is a helpful tool in early detecting local tumor residues and metastases. The decision making for further radiotherapeutical measures will be much easier, if accompanying tumor marker determinations have been done during primary radiotherapy. PMID:2200151

Paths to destruction: the lives and crimes of two serial killers.  

PubMed

Although research into the phenomenon of serial murder has revealed that serial killers frequently do not fit the initially described paradigm in terms of their physical and psychological profiles, backgrounds, and motives to kill, the media continues to sensationalize the figures of such killers and the investigators who attempt to analyze them on the basis of aspects of their crimes. Although the so-called "typical" profile of the serial murderer has proven accurate in some instances, in many other cases the demographics and behaviors of these killers have deviated widely from the generalized assumptions. This report details two unusual cases in which five and eight murders were committed in upstate New York. The lives and crimes of these offenders illustrate the wide spectrum of variations in the backgrounds, demographics, motivations, and actions witnessed among serial murderers, and highlight the limitations and dangers of profiling based on generalities.
