Making COD statistics useful for public health at local level in the city of Cape Town: utilidad para la salud p?blica a nivel local en Ciudad del Cabo.  

PubMed Central

OBJECTIVE: To review the quality of the coding of the cause of death (COD) statistics and assess the mortality information needs of the City of Cape Town. METHODS: Using an action research approach, a study was set up to investigate the quality of COD information, the accuracy of COD coding and consistency of coding practices in the larger health subdistricts. Mortality information needs and the best way of presenting the statistics to assist health managers were explored. FINDINGS: Useful information was contained in 75% of death certificates, but nearly 60% had only a single cause certified; 55% of forms were coded accurately. Disagreement was mainly because routine coders coded the immediate instead of the underlying COD. An abridged classification of COD, based on causes of public health importance, prevalent causes and selected combinations of diseases was implemented with training on underlying cause. Analysis of the 2001 data identified the leading causes of death and premature mortality and illustrated striking differences in the disease burden and profile between health subdistricts. CONCLUSION: Action research is particularly useful for improving information systems and revealed the need to standardize the coding practice to identify underlying cause. The specificity of the full ICD classification is beyond the level of detail on the death certificates currently available. An abridged classification for coding provides a practical tool appropriate for local level public health surveillance. Attention to the presentation of COD statistics is important to enable the data to inform decision-makers.

DelPhi: a comprehensive suite for DelPhi software and associated resources  

PubMed Central

Background Accurate modeling of electrostatic potential and corresponding energies becomes increasingly important for understanding properties of biological macromolecules and their complexes. However, this is not an easy task due to the irregular shape of biological entities and the presence of water and mobile ions. Results Here we report a comprehensive suite for the well-known Poisson-Boltzmann solver, DelPhi, enriched with additional features to facilitate DelPhi usage. The suite allows for easy download of both DelPhi executable files and source code along with a makefile for local installations. The users can obtain the DelPhi manual and parameter files required for the corresponding investigation. Non-experienced researchers can download examples containing all necessary data to carry out DelPhi runs on a set of selected examples illustrating various DelPhi features and demonstrating DelPhi’s accuracy against analytical solutions. Conclusions DelPhi suite offers not only the DelPhi executable and sources files, examples and parameter files, but also provides links to third party developed resources either utilizing DelPhi or providing plugins for DelPhi. In addition, the users and developers are offered a forum to share ideas, resolve issues, report bugs and seek help with respect to the DelPhi package. The resource is available free of charge for academic users from URL: http://compbio.clemson.edu/DelPhi.php.

Local hyperdynamics.  

PubMed

We present a new formulation of the hyperdynamics method in which the biasing effect is local, making it suitable for large systems. In standard hyperdynamics, the requirement that the bias potential be zero everywhere on the dividing surface bounding the state has the consequence that as the system size increases the boost factor decays to unity, regardless of the form of the bias potential. In the new method, the bias force on each atom is obtained by differentiating a local bias energy that depends only on the coordinates of atoms within a finite range of this atom. This bias force is thus independent of the bias force in distant parts of the system, providing a method that gives a constant boost factor, independent of the system size. We demonstrate for some realistic atomistic systems that the method gives escape rates in excellent agreement with direct molecular dynamics simulations. PMID:24116606

We present a new formulation of the hyperdynamics method in which the biasing effect is local, making it suitable for large systems. In standard hyperdynamics, the requirement that the bias potential be zero everywhere on the dividing surface bounding the state has the consequence that for large systems the boost factor decays to unity, regardless of the form of the bias potential. In the new method, the bias force on each atom is obtained by differentiating a local bias energy that depends only on the coordinates of atoms within a finite range D of this atom. This bias force is thus independent of the bias force in distant parts of the system, providing a method that gives a constant boost factor, independent of the system size. Although the resulting dynamics are no longer conservative, we show that for a homogeneous system (all atoms equivalent) using a simplifed bond-boost bias potential, the bias forces in any local region are equivalent to those in a system accelerated by a specific boost factor, except for additional error forces that balance in a time average. We also argue that even for inhomogeneous systems, the errors relative to an exactly accelerated dynamics should should decay roughly as 1/D. We demonstrate for some realistic atomistic systems that the method gives escape rates in excellent agreement with direct molecular dynamics simulations.

Quantum Locality  

NASA Astrophysics Data System (ADS)

It is argued that while quantum mechanics contains nonlocal or entangled states, the instantaneous or nonlocal influences sometimes thought to be present due to violations of Bell inequalities in fact arise from mistaken attempts to apply classical concepts and introduce probabilities in a manner inconsistent with the Hilbert space structure of standard quantum mechanics. Instead, Einstein locality is a valid quantum principle: objective properties of individual quantum systems do not change when something is done to another noninteracting system. There is no reason to suspect any conflict between quantum theory and special relativity.

The leukocyte integrin antagonist Del-1 inhibits IL-17-mediated inflammatory bone loss  

PubMed Central

Aging is linked to increased susceptibility to chronic inflammatory diseases several of which, including periodontitis, involve neutrophil-mediated tissue injury. Here, we found that aging-associated periodontitis was accompanied by diminished expression of Del-1 (EDIL3), an endogenous inhibitor of LFA-1 integrin-dependent neutrophil adhesion, and by a reciprocal increase in IL-17 expression. Consistently, IL-17 inhibited gingival endothelial cell expression of Del-1, thereby promoting LFA-1-dependent neutrophil recruitment. Young Del-1-deficient mice developed spontaneous periodontitis featuring excessive neutrophil infiltration and IL-17 expression; disease was prevented in Del-1–LFA-1 and Del-1–IL-17 receptor double-deficient mice. Locally administered Del-1 inhibited IL-17 production, neutrophil accumulation, and bone loss. Therefore, Del-1 suppresses LFA-1-dependent neutrophil recruitment and IL-17-triggered inflammatory pathology and may thus be a promising therapeutic for inflammatory diseases.

Novel WDR72 Mutation and Cytoplasmic Localization  

PubMed Central

The proven candidate genes for amelogenesis imperfecta (AI) are AMELX, ENAM, MMP20, KLK4, FAM83H, and WDR72. We performed mutation analyses on seven families with hypomaturation AI. A novel WDR72 dinucleotide deletion mutation (g.57,426_57,427delAT; c.1467_ 1468delAT; p.V491fsX497) was identified in both alleles of probands from Mexico and Turkey. Haplotype analyses showed that the mutations arose independently in the two families. The disease perfectly segregated with the genotype. Only persons with both copies of the mutant allele were affected. Their hypomineralized enamel suffered attrition and orange-brown staining following eruption. Expression of WDR72 fused to green fluorescent protein showed a cytoplasmic localization exclusively and was absent from the nucleus. We conclude that WDR72 is a cytoplasmic protein that is critical for dental enamel formation.

How local is the local field potential?  

PubMed Central

Summary Local field potentials (LFPs) are of growing importance in neurophysiological investigations. LFPs supplement action potential recordings by indexing activity relevant to EEG, MEG and hemodynamic (fMRI) signals. Recent reports suggest that LFPs reflect activity within very small domains of several hundred microns. We examined this conclusion by comparing LFP, current source density (CSD), and multiunit activity (MUA) signals in macaque auditory cortex. Estimated by frequency tuning bandwidths, these signals' “listening areas” differ systematically with an order of: MUA < CSD < LFP. Computational analyses confirm that observed LFPs receive non-local contributions. Direct measurements indicate passive spread of LFPs to sites more than a centimeter from their origins. These findings appear to be independent of the frequency content of the LFP. Our results challenge the idea that LFP recordings typically integrate over extremely circumscribed local domains. Rather, LFPs appear as a mixture of local potentials with “volume conducted” potentials from distant sites.

Temporal Non-locality  

NASA Astrophysics Data System (ADS)

In this article I investigate several possibilities to define the concept of "temporal non-locality" within the standard framework of quantum theory. In particular, I analyze the notions of "temporally non-local states", "temporally non-local events" and "temporally non-local observables". The idea of temporally non-local events is already inherent in the standard formalism of quantum mechanics, and Basil Hiley recently defined an operator in order to measure the degree of such a temporal non-locality. The concept of temporally non-local states enters as soon as "clock-representing states" are introduced in the context of special and general relativity. It is discussed in which way temporally non-local measurements may find an interesting application for experiments which test temporal versions of Bell inequalities.

Localized Components Analysis  

PubMed Central

We introduce Localized Components Analysis (LoCA) for describing surface shape variation in an ensemble of biomedical objects using a linear subspace of spatially localized shape components. In contrast to earlier methods, LoCA optimizes explicitly for localized components and allows a flexible trade-off between localized and concise representations. Experiments comparing LoCA to a variety of competing shape representation methods on 2D and 3D shape ensembles establish the superior ability of LoCA to modulate the locality-conciseness trade-off and generate shape components corresponding to intuitive modes of shape variation. Our formulation of locality in terms of compatibility between pairs of surface points is shown to be flexible enough to enable spatially-localized shape descriptions with attractive higher-order properties such as spatial symmetry.

Localization by bichromatic potentials versus Anderson localization  

SciTech Connect

The one-dimensional propagation of waves in a bichromatic potential may be modeled by the Aubry-Andre Hamiltonian. This, in turn, presents a localization transition that has been observed in recent experiments using ultracold atoms or light. It is shown here that, in contrast to the Anderson model, the localization mechanism has a classical origin, namely it is not due to a quantum suppression of a classically allowed transport process, but rather is produced by a trapping by the potential. Explicit comparisons with the Anderson model as well as with experiments are presented.

Decohering localized waves.  

PubMed

In the absence of confinement, localization of waves takes place due to randomness or nonlinearity and relies on their phase coherence. We quantitatively probe the sensitivity of localized wave packets to random phase fluctuations and confirm the necessity of phase coherence for localization. Decoherence resulting from a dynamical random environment leads to diffusive spreading and destroys linear and nonlinear localization. We find that maximal spreading is achieved for optimal phase fluctuation characteristics, which is a consequence of the competition between diffusion due to decoherence and ballistic transport within the mean free path distance.

Localization of magnetic pills  

PubMed Central

Numerous therapeutics demonstrate optimal absorption or activity at specific sites in the gastrointestinal (GI) tract. Yet, safe, effective pill retention within a desired region of the GI remains an elusive goal. We report a safe, effective method for localizing magnetic pills. To ensure safety and efficacy, we monitor and regulate attractive forces between a magnetic pill and an external magnet, while visualizing internal dose motion in real time using biplanar videofluoroscopy. Real-time monitoring yields direct visual confirmation of localization completely noninvasively, providing a platform for investigating the therapeutic benefits imparted by localized oral delivery of new and existing drugs. Additionally, we report the in vitro measurements and calculations that enabled prediction of successful magnetic localization in the rat small intestines for 12 h. The designed system for predicting and achieving successful magnetic localization can readily be applied to any area of the GI tract within any species, including humans. The described system represents a significant step forward in the ability to localize magnetic pills safely and effectively anywhere within the GI tract. What our magnetic pill localization strategy adds to the state of the art, if used as an oral drug delivery system, is the ability to monitor the force exerted by the pill on the tissue and to locate the magnetic pill within the test subject all in real time. This advance ensures both safety and efficacy of magnetic localization during the potential oral administration of any magnetic pill-based delivery system.

Anderson localized optical fibers  

NASA Astrophysics Data System (ADS)

Anderson localization has been a subject of fascination and intense research for more than fifty years. It is highly desirable to harness its curious and interesting properties in practical applications. We have taken a step in this direction by using this phenomenon as the wave guiding mechanism in optical fibers. We have shown, both experimentally and numerically, that for a moderate amount of disorder in optical fibers, transverse localization results in an effective propagating beam diameter that is comparable to that of a typical index-guiding optical fiber.1, 2 In this work, we investigate the effect of macro-bending on the localization properties in a disordered polymer optical fiber both experimentally and numerically. We show that macro-bending in ranges of practical interest does not significantly affect the beam propagation in Anderson localized fibers as long as the strong localization dominates the effect of bending.

Explosion localization via infrasound.  

PubMed

Two acoustic source localization techniques were applied to infrasonic data and their relative performance was assessed. The standard approach for low-frequency localization uses an ensemble of small arrays to separately estimate far-field source bearings, resulting in a solution from the various back azimuths. This method was compared to one developed by the authors that treats the smaller subarrays as a single, meta-array. In numerical simulation and a field experiment, the latter technique was found to provide improved localization precision everywhere in the vicinity of a 3-km-aperture meta-array, often by an order of magnitude.

Ocular surgery presents some particularities: local anesthesia continues to be the most utilized and it consists in topical corneo-conjunctival anesthesia and local or regional infiltrative anesthesia. The term of locoregional anesthesia is utilized in ophthalmology for the reason that the two forms of anesthesia could be associated. In this paper the authors insist on different types and methods of anesthesia utilized in ophthalmology and on indications and benefits of each method. There are also presented the incidents and complications of local anesthesia in ophthalmology. PMID:19899543

Locality and parsing complexity.

Two experiments, an off-line acceptability judgment study and an on-line self-paced reading experiment, were conducted to tackle the question of locality-based preferences in sentence processing. The material consisted of German verb-final sentences containing a relative clause that was either host adjacent or extraposed. While the off-line data seem to reflect locality based integration cost, the on-line data revealed a highly different picture. It is argued that, in the present constructions at least, locality is relevant for production rather than perception. In perception, heads can be anticipated through incremental integration of their arguments. PMID:11196066

Local Coordinates Model  

NSDL National Science Digital Library

The Local Coordinates model displays the position of a star in local (Altitude/Azimuth) coordinates. The horizon is shown along with the four cardinal directions (N, E, S, and W). The latitude of the observer is set at 35.5 degrees which sets the location of the north celestial pole (teal) relative to the northern horizon. The position of the star can be changed by using the Altitude and Azimuth sliders. The Local Coordinates model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_astronomy_Local Coordinates.jar file will run the program if Java is installed. EJS is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.

Local entropy generation analysis  

SciTech Connect

Second law analysis techniques have been widely used to evaluate the sources of irreversibility in components and systems of components but the evaluation of local sources of irreversibility in thermal processes has received little attention. While analytical procedures for evaluating local entropy generation have been developed, applications have been limited to fluid flows with analytical solutions for the velocity and temperature fields. The analysis of local entropy generation can be used to evaluate more complicated flows by including entropy generation calculations in a computational fluid dynamics (CFD) code. The research documented in this report consists of incorporating local entropy generation calculations in an existing CFD code and then using the code to evaluate the distribution of thermodynamic losses in two applications: an impinging jet and a magnetic heat pump. 22 refs., 13 figs., 9 tabs.

Parathyroid adenoma Localization  

PubMed Central

Background Bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. But surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance. Method 80 patients with documented primary hyperparathyroidism and with raised serum calcium and parathyroid hormone (PTH) were selected. The results of ultrasonographic localization for each patient were compared with findings of surgery and 99m technetium sestamibi scintigraphy. Also variables such as preoperative serum calcium, PTH level and adenoma weight were compared between patients who had localized and non-localized adenoma with ultrasonography or Sestamibi scan. The data was compared with student's t-test. Results In a prospective diagnostic tests accuracy study, 80 patients with primary hyperparathyroidism were enrolled. Ultrasonography images detected enlarged parathyroid glands in 61 of 80 patients (76.3%) with sensitivity of 83.5% and positive predictive value (PPV) of 89.7%. Sestamibi scintigraphy detected adenoma in 63 patients (78.8%) with sensitivity of 85% and PPV of 91.3%. There was no significant deference between ultrasonography and scintigraphy in localization of adenomas. Both ultrasonography and scintigraphy used for determining localization, and they located 73 adenomas (91.3%) with sensitivity of 97.3% and PPV of 93.5%. Conclusion Ultrasonography as an accurate method for localization of enlarged parathyroid glands in primary hyperparathyroidism, is comparable in overall utility with sestamibi scintigraphy. This study suggests a strategy for initial testing with one method, followed by the alternate imaging test if the first test happens to be negative.

Anderson Localization of Solitons

At low temperature, a quasi-one-dimensional ensemble of atoms with an attractive interaction forms a bright soliton. When exposed to a weak and smooth external potential, the shape of the soliton is hardly modified, but its center-of-mass motion is affected. We show that in a spatially correlated disordered potential, the quantum motion of a bright soliton displays Anderson localization. The localization length can be much larger than the soliton size and could be observed experimentally.

Local relativistic exact decoupling  

NASA Astrophysics Data System (ADS)

We present a systematic hierarchy of approximations for local exact decoupling of four-component quantum chemical Hamiltonians based on the Dirac equation. Our ansatz reaches beyond the trivial local approximation that is based on a unitary transformation of only the atomic block-diagonal part of the Hamiltonian. Systematically, off-diagonal Hamiltonian matrix blocks can be subjected to a unitary transformation to yield relativistically corrected matrix elements. The full hierarchy is investigated with respect to the accuracy reached for the electronic energy and for selected molecular properties on a balanced test molecule set that comprises molecules with heavy elements in different bonding situations. Our atomic (local) assembly of the unitary exact-decoupling transformation--called local approximation to the unitary decoupling transformation (DLU)--provides an excellent local approximation for any relativistic exact-decoupling approach. Its order-N2 scaling can be further reduced to linear scaling by employing a neighboring-atomic-blocks approximation. Therefore, DLU is an efficient relativistic method well suited for relativistic calculations on large molecules. If a large molecule contains many light atoms (typically hydrogen atoms), the computational costs can be further reduced by employing a well-defined nonrelativistic approximation for these light atoms without significant loss of accuracy. We also demonstrate that the standard and straightforward transformation of only the atomic block-diagonal entries in the Hamiltonian--denoted diagonal local approximation to the Hamiltonian (DLH) in this paper--introduces an error that is on the order of the error of second-order Douglas-Kroll-Hess (i.e., DKH2) when compared with exact-decoupling results. Hence, the local DLH approximation would be pointless in an exact-decoupling framework, but can be efficiently employed in combination with the fast to evaluate DKH2 Hamiltonian in order to speed up calculations for which ultimate accuracy is not the major concern.

Localizations on complex networks.  

PubMed

We study the structural characteristics of complex networks using the representative eigenvectors of the adjacent matrix. The probability distribution function of the components of the representative eigenvectors are proposed to describe the localization on networks where the Euclidean distance is invalid. Several quantities are used to describe the localization properties of the representative states, such as the participation ratio, the structural entropy, and the probability distribution function of the nearest neighbor level spacings for spectra of complex networks. Whole-cell networks in the real world and the Watts-Strogatz small-world and Barabasi-Albert scale-free networks are considered. The networks have nontrivial localization properties due to the nontrivial topological structures. It is found that the ascending-order-ranked series of the occurrence probabilities at the nodes behave generally multifractally. This characteristic can be used as a structural measure of complex networks. PMID:18643342

Local bifurcation control  

NASA Astrophysics Data System (ADS)

Local feedback stabilization of bifurcated solution branches is studied. Two cases are considered: that in which the nominal system undergoes a Hopf bifurcation as a parameter is varied, and the case of a stationary bifurcation from a simple zero eigenvalue. For each case, results on the existence of a stabilizing feedback are given. Moreover, simple synthesis techniques for the stabilizing controllers are discussed. A concept of proximity stabilization is introduced as an alternative to stabilization in the ordinary sense for systems that are not locally stabilizable. A result is stated on the generic character of proximity stabilizability. Motivation for further research in several areas is given.

Transverse localization of sound

We show how disorder can be used to guide a broadband ultrasonic wave. The idea is to exploit the transverse localization regime that has been reported for light. Our waveguide consists of a set of parallel cylindrical scatterers randomly distributed in the transverse plane. An ultrasonic beam propagating along the direction of scatterers is found to remain confined in the two other directions on a size smaller than the waveguide diameter and driven by the localization length. Interestingly, the guided wave is also found to propagate with a very limited temporal dispersion.

Principle of relative locality  

SciTech Connect

We propose a deepening of the relativity principle according to which the invariant arena for nonquantum physics is a phase space rather than spacetime. Descriptions of particles propagating and interacting in spacetimes are constructed by observers, but different observers, separated from each other by translations, construct different spacetime projections from the invariant phase space. Nonetheless, all observers agree that interactions are local in the spacetime coordinates constructed by observers local to them. This framework, in which absolute locality is replaced by relative locality, results from deforming energy-momentum space, just as the passage from absolute to relative simultaneity results from deforming the linear addition of velocities. Different aspects of energy-momentum space geometry, such as its curvature, torsion and nonmetricity, are reflected in different kinds of deformations of the energy-momentum conservation laws. These are in principle all measurable by appropriate experiments. We also discuss a natural set of physical hypotheses which singles out the cases of energy-momentum space with a metric compatible connection and constant curvature.

A local dissipation theorem.  

PubMed

The transient time correlation function is a standard method for measuring transport properties in simulations. It represents a special case of a more general theorem, the dissipation theorem, that indirectly calculates phase function averages though the use of the dissipation function. These indirect averages often have significantly less statistical error than direct averages. Recently, it has been demonstrated that a local version of the fluctuation theorem can be derived with a well defined deviation from the global result at sufficiently low fields. Here we show that a similar local expression can be obtained for the dissipation theorem, providing a way of determining values of phase functions by monitoring the fluctuations of phase functions in a small region of the system.

Bayesian Radiation Source Localization  

SciTech Connect

Locating illicit radiological sources using gamma ray or neutron detection is a key challenge for both homeland security and nuclear nonproliferation. Localization methods using an array of detectors or a sequence of observations in time and space must provide rapid results while accounting for a dynamic attenuating environment. In the presence of significant attenuation and scatter, more extensive numerical transport calculations in place of the standard analytical approximations may be required to achieve accurate results. Numerical adjoints based on deterministic transport codes provide relatively efficient detector response calculations needed to determine the most likely location of a true source. Probabilistic representations account for uncertainty in the source location resulting from uncertainties in detector responses, the approximations that are used, and the potential for nonunique solutions. A Bayesian approach improves on previous likelihood methods for source localization by allowing the incorporation of all available information to help constrain solutions.

Acoustic source localization.  

PubMed

In this article different techniques for localizing acoustic sources are described and the advantages/disadvantages of these techniques are discussed. Some source localization techniques are restricted to isotropic structures while other methods can be applied to anisotropic structures as well. Some techniques require precise knowledge of the direction dependent velocity profiles in the anisotropic body while other techniques do not require that knowledge. Some methods require accurate values of the time of arrival of the acoustic waves at the receivers while other techniques can function without that information. Published papers introducing various techniques emphasize the advantages of the introduced techniques while ignoring and often not mentioning the limitations and weaknesses of the new techniques. What is lacking in the literature is a comprehensive review and comparison of the available techniques; this article attempts to do that. After reviewing various techniques the paper concludes which source localization technique should be most effective for what type of structure and what the current research needs are. PMID:23870388

Kinematic strain localization  

NASA Astrophysics Data System (ADS)

Deformation within a steady-state compressional orogen, i.e., where tectonic accretion is, on geological time scales, balanced by surface erosion, can best be described by a stationary velocity field. Instantaneous deformation results from spatial gradients in the velocity field, whereas total accumulated strain results from the integration of this instantaneous deformation along material paths following the flow lines defined by the velocity field. We have synthesized the net strain distributions for rocks exposed at the surface of such an orogenic system using simple, linear velocity fields corresponding to (a) simple shear within a dipping shear zone and (b) pure vertical shear. In both cases we demonstrate the development of surface patterns of finite strain accumulation that do not reflect the geometry of the assumed velocity field in a simple manner. Large gradients in finite strain arise as a consequence of the geographic variation in particle residence time imposed by the surface boundary, even for the limiting case where no instantaneous strain gradient exists. Such patterns of deformation are often recognised in exhumed orogenic systems, but have commonly been assumed to reflect more complex velocity fields resulting from nonlinear, localizing crustal rheologies. We therefore demonstrate that caution should be exercised in interpreting observed strain patterns because a proportion of the observed strain localization must be attributed to this purely kinematic (or geometric) effect — and this proportion may be significant in many systems. Such kinematic effects should be quantified, and subtracted from observed strain distributions before they are used to infer the rheological behavior of crustal rocks. We also suggest that in a simple shear (thrust) setting, kinematic strain localization may in fact nucleate strain softening on the side of the deforming region that is stable or fixed with respect to the Earth's surface and thus be responsible for the asymmetry that characterizes the large majority of thrust systems.

Spatio-temporally quasi-nondiffracting pulses propagating along extended zones are shaped from Ti:sapphire oscillator radiation with a spatial light modulator and characterized with spatially resolved second order autocorrelation. Few-cycle wavepackets tailored to resemble circular disks, rings and bars of light represent the closest approximation of linear-optical light bullets known so far. By combining multiple HLWs, complex pulsed nondiffracting patterns are obtained. PMID:22714244

Locality and reality  

SciTech Connect

Einstein's principle that no signal travels faster than light suggests that observations in one spacetime region should not depend on whether or not a radioactive decay is detected in a spacelike-separated region. This locality property is incompatible with the predictions of quantum theory, and this incompatibility holds independently of the questions of realism, objective reality, and hidden variables. It holds both in the pragmatic quantum theory of Bohr and in realistic frameworks. It is shown here to hold in a completed realistic quantum theory that reconciles Einstein's demand for a description of reality itself with Bohr's contention that quantum theory is complete. This completed realistic quantum theory has no hidden variables, and no objective reality in which observable attributes can become definite independently of observers. The theory is described in some detail, with particular attention to those aspects related to the question of locality. This completed realistic quantum theory is in principle more comprehensive than Bohn's pragmatic quantum theory because it is not limited in principle by the requirement that the observed system be physically separated from the observing one. Applications are discussed.

Ectopic localization of tungiasis.  

PubMed

Tungiasis is caused by the penetration of the female sand flea Tunga penetrans into the epidermis. It is generally assumed that lesions are confined to the feet. To determine to what degree tungiasis occurs at other topographic sites, 1,184 inhabitants of a poor neighborhood in northeastern Brazil were examined; 33.6% were found to have tungiasis (95% confidence interval = 30.9-36.4%). Six percent presented lesions at locations other than the feet, with the hands being the most common ectopic site (5.5%). Other sites were the elbows, thighs, and gluteal region. Ectopic tungiasis was significantly associated with the total number of lesions (P < 0.001) and an age less than 15 years old (P = 0.02). In 86 patients actively recruited with lesions on their feet, ectopic localizations were observed in 25.6%. Since untreated sand flea lesions are prone to become superinfected, clinicians should be aware of not missing any ectopic localization of tungiasis. PMID:12389950

Passive Acoustic Vessel Localization  

NASA Astrophysics Data System (ADS)

This thesis investigates the development of a low-cost passive acoustic system for localizing moving vessels to monitor areas where human activities such as fishing, snorkeling and poaching are restricted. The system uses several off-the-shelf sensors with unsynchronized clocks where the Time Difference of Arrival (TDOA) or time delay is extracted by cross-correlation of the signal between paired sensors. The cross-correlation function uses phase correlation or Phase Transform (PHAT) which whitens the cross-spectrum in order to de-emphasize dominant frequency components. Using the locations of pairs of sensors as foci, hyperbolic equations can be defined using the time delay between them. With three or more sensors, multiple hyperbolic functions can be calculated which intersect at a unique point: the boat's location. It is also found that increasing separation distances between sensors decreased the correlation between the signals. However larger separation distances have better localization capability than with small distances. Experimental results from the Columbia and Willamette Rivers are presented to demonstrate performance.

Among the technologies considered for this task acoustics is a natural choice for various reasons. The acoustic signatures of gunshots are loud and distinctive, making them easy to detect even in high noise background environments. Acoustics provides a passive sensing technology with excellent range and non line of sight capabilities. Last but not least, an acoustic sniper location system can be built at a low cost with off the shelf components. Despite its many advantages, the performance of acoustic sensors can degrade under adverse propagation conditions. Localization accuracy, although good, is usually not accurate enough to pinpoint a sniper's location in some scenarios (for example which widow in a building or behind which tree in a grove). For these more demanding missions, the acoustic sensor can be used in conjunction with an infra red imaging system that detects the muzzle blast of the gun. The acoustic system can be used to cue the pointing system of the IR camera in the direction of the shot's source.

Pattern Driven Stress Localization  

NASA Astrophysics Data System (ADS)

The self-assembly of patterns from isotropic initial states is a major driver of modern soft-matter research. This avenue of study is directed by the desire to understand the complex physics of the varied structures found in Nature, and by technological interest in functional materials that may be derived through biomimicry. In this work we show how a simple striped phase can respond with significant complexity to an appropriately chosen perturbation. In particular, we show how a buckled elastic plate transitions into a state of stress localization using a simple, self-assembled variation in surface topography. The collection of topographic boundaries act in concert to change the state from isotropic sinusoidal wrinkles, to sharp folds or creases separated by relatively flat regions. By varying the size of the imposed topographic pattern or the wavelength of the wrinkles, we construct a state diagram of the system. The localized state has implications for both biological systems, and for the control of non-linear pattern formation.

Localization-protected quantum order  

NASA Astrophysics Data System (ADS)

Closed quantum systems with quenched randomness exhibit many-body localized regimes wherein they do not equilibrate, even though prepared with macroscopic amounts of energy above their ground states. We show that such localized systems can order, in that individual many-body eigenstates can break symmetries or display topological order in the infinite-volume limit. Indeed, isolated localized quantum systems can order even at energy densities where the corresponding thermally equilibrated system is disordered, i.e., localization protects order. In addition, localized systems can move between ordered and disordered localized phases via nonthermodynamic transitions in the properties of the many-body eigenstates. We give evidence that such transitions may proceed via localized critical points. We note that localization provides protection against decoherence that may allow experimental manipulation of macroscopic quantum states. We also identify a “spectral transition” involving a sharp change in the spectral statistics of the many-body Hamiltonian.

Global Versus Local CSR Strategies  

Microsoft Academic Search

Perspectives differ on whether multinationals (MNEs) should develop centrally coordinated, 'global' corporate social responsibility (CSR) strategies, or whether they should stimulate decentralized, 'local' CSR strategies. A global strategy might involve an efficient transmission of (proactive) CSR practices throughout the organization worldwide, but may also lack ownership and legitimacy at the local level. While much more responsive, a local strategy could

Local control stations  

SciTech Connect

This paper describes research concerning the effects of human engineering design at local control stations (i.e., operator interfaces located outside the control room) on human performance and plant safety. The research considered both multifunction panels (e.g. remote shutdown panels) as well as single-function interfaces (e.g., valves, breakers, gauges, etc.). Changes in performance shaping factors associated with variations in human engineering at LCSs were estimated based on expert opinion. By means of a scaling procedure, these estimates were used to modify the human error probabilities in a PRA model, which was then employed to generate estimates of plant risk and scoping-level value/impact ratios for various human engineering upgrades. Recent documentation of human engineering deficiencies at single-function LCSs was also reviewed, and an assessment of the current status of LCSs with respect to human engineering was conducted.

Sleep locally, act globally.  

PubMed

In most animals, sleep is considered a global brain and behavioral state. However, recent intracortical recordings have shown that aspects of non-rapid eye movement (NREM) sleep and wakefulness can occur simultaneously in different parts of the cortex in mammals, including humans. Paradoxically, however, NREM sleep still manifests as a global behavioral shutdown. In this review, the authors examine this paradox from an evolutionary perspective. On the basis of strategic modeling, they suggest that in animals with brains composed of heavily interconnected and functionally interdependent units, a global regulator of sleep maintains the behavioral shutdown that defines sleep and thereby ensures that local use-dependent functions are performed in a safe and efficient manner. This novel perspective has implications for understanding deficits in human cognitive performance resulting from sleep deprivation, sleep disorders such as sleepwalking, changes in consciousness that occur during sleep, and the function of sleep itself.

Stable local oscillator microcircuit.  

SciTech Connect

This report gives a description of the development of a Stable Local Oscillator (StaLO) Microcircuit. The StaLO accepts a 100MHz input signal and produces output signals at 1.2, 3.3, and 3.6 GHz. The circuit is built as a multi-chip module (MCM), since it makes use of integrated circuit technologies in silicon and lithium niobate as well as discrete passive components. The StaLO uses a comb generator followed by surface acoustic wave (SAW) filters. The comb generator creates a set of harmonic components of the 100MHz input signal. The SAW filters are narrow bandpass filters that are used to select the desired component and reject all others. The resulting circuit has very low sideband power levels and low phase noise (both less than -40dBc) that is limited primarily by the phase noise level of the input signal.

Localized wave pulse experiments  

SciTech Connect

The Localized Wave project of the Strategic System Support Program has recently finished an experiment in cooperation with the Advanced SONAR group of the Applied Research Laboratory of the University of Texas at Austin. The purpose of the experiment was three-fold. They wanted to see if (1) the LW pulse could propagate over significant distances, to see if (2) a new type of array and drive system specifically designed for the pulse would increase efficiency over single frequency tone bursts, and to see if (3) the complexity of our 24 channel drivers resulted in better efficiency than a single equivalent pulse driving a piston. In the experiment, several LW pulses were launched from the Lake Travis facility and propagated over distances of either 100 feet or 600 feet, through a thermocline for the 600 foot measurements. The results show conclusively that the Localized Wave will propagate past the near field distance. The LW pulses resulted in extremely broad frequency band width pulses with narrow spatial beam patterns and unmeasurable side lobes. Their array gain was better than most tone bursts and further, were better than their equivalent piston pulses. This marks the first test of several Low Diffraction beams against their equivalent piston pulses, as well as the first propagation of LW pulses over appreciable distances. The LW pulse is now proven a useful tool in open water, rather than a laboratory curiosity. The experimental system and array were built by ARL, and the experiments were conducted by ARL staff on their standard test range. The 600 feet measurements were made at the farthest extent of that range.

Boundary localization in texture segmentation.  

PubMed

Localizing boundaries between textured image regions without sacrificing the labeling accuracy of interior regions remains a problem in segmentation. Difficulties arise because of the conflicting requirements of localization and labeling. Boundary localization usually demands observing the features over small neighborhoods, whereas labeling accuracy increases with the size of the observation neighborhood. This problem is further exacerbated in texture segmentation by the spatially distributed nature of texture features. In this correspondence, we develop a multiresolution approach that combines localized and distributed features to directly address boundary localization in texture segmentation. Maximum localization is achieved by using the gray-level discontinuities at the boundary between textures to define the boundary. The properties that characterize the gray-level discontinuity at texture boundaries are developed and an algorithm is designed to localize the boundary using these discontinuities. This segmentation algorithm is implemented and successfully tested on a set of Brodatz texture mosaics and AVHRR satellite imagery. PMID:18290036

Local Sparse Bump Hunting  

PubMed Central

The search for structures in real datasets e.g. in the form of bumps, components, classes or clusters is important as these often reveal underlying phenomena leading to scientific discoveries. One of these tasks, known as bump hunting, is to locate domains of a multidimensional input space where the target function assumes local maxima without pre-specifying their total number. A number of related methods already exist, yet are challenged in the context of high dimensional data. We introduce a novel supervised and multivariate bump hunting strategy for exploring modes or classes of a target function of many continuous variables. This addresses the issues of correlation, interpretability, and high-dimensionality (p ? n case), while making minimal assumptions. The method is based upon a divide and conquer strategy, combining a tree-based method, a dimension reduction technique, and the Patient Rule Induction Method (PRIM). Important to this task, we show how to estimate the PRIM meta-parameters. Using accuracy evaluation procedures such as cross-validation and ROC analysis, we show empirically how the method outperforms a naive PRIM as well as competitive non-parametric supervised and unsupervised methods in the problem of class discovery. The method has practical application especially in the case of noisy high-throughput data. It is applied to a class discovery problem in a colon cancer micro-array dataset aimed at identifying tumor subtypes in the metastatic stage. Supplemental Materials are available online.

Knot localization in proteins.  

PubMed

The backbones of proteins form linear chains. In the case of some proteins, these chains can be characterized as forming linear open knots. The knot type of the full chain reveals only limited information about the entanglement of the chain since, for example, subchains of an unknotted protein can form knots and subchains of a knotted protein can form different types of knots than the entire protein. To understand fully the entanglement within the backbone of a given protein, a complete analysis of the knotting within all of the subchains of that protein is necessary. In the present article, we review efforts to characterize the full knotting complexity within individual proteins and present a matrix that conveys information about various aspects of protein knotting. For a given protein, this matrix identifies the precise localization of knotted regions and shows the knot types formed by all subchains. The pattern in the matrix can be considered as a knotting fingerprint of that protein. We observe that knotting fingerprints of distantly related knotted proteins are strongly conserved during evolution and discuss how some characteristic motifs in the knotting fingerprints are related to the structure of the knotted regions and their possible biological role.

All strategy is local.  

PubMed

The aim of strategy is to master a market environment by understanding and anticipating the actions of other economic agents, especially competitors. A firm that has some sort of competitive advantage-privileged access to customers, for instance--will have relatively few competitors to contend with, since potential competitors without an advantage, if they have their wits about them, will stay away. Thus, competitive advantages are actually barriers to entry and vice versa. In markets that are exposed, by contrast, competition is intense. If the incumbents have even brief success in earning greater than normal returns on investments, new entrants will swarm in to grab a share of the profits. Sooner or later, the additional competition will push returns as far down as the firms' costs of capital. For firms operating in such markets, the only choice is to forget about strategy and run the business as efficiently as possible. Barriers to entry are easier to maintain in a competitive arena that is "local", either in the geographic sense or in the sense of being limited to one product or a handful of related ones. The two most powerful competitive advantages-customer captivity and economies of scale-are more achievable and sustainable in circumscribed markets of this kind. Their opposites are the open markets and host of rivals that are features of globalization. Compapies entering such markets risk frittering away the advantages they secured on smaller playing fields.., Ifa company wants to grow but still obtain superior returns, the authors argue, the best strategy is to dominate a series of discrete but preferably contiguous markets and then expand only at their edges. WalMart's diminishing margins over the past 15 years are strong evidence of the danger of proceeding otherwise. PMID:16171214

Causal learning with local computations.  

PubMed

The authors proposed and tested a psychological theory of causal structure learning based on local computations. Local computations simplify complex learning problems via cues available on individual trials to update a single causal structure hypothesis. Structural inferences from local computations make minimal demands on memory, require relatively small amounts of data, and need not respect normative prescriptions as inferences that are principled locally may violate those principles when combined. Over a series of 3 experiments, the authors found (a) systematic inferences from small amounts of data; (b) systematic inference of extraneous causal links; (c) influence of data presentation order on inferences; and (d) error reduction through pretraining. Without pretraining, a model based on local computations fitted data better than a Bayesian structural inference model. The data suggest that local computations serve as a heuristic for learning causal structure. PMID:19379043

Groundwater parameter estimation using the ensemble Kalman filter with localization  

NASA Astrophysics Data System (ADS)

The ensemble Kalman filter (EnKF), an efficient data assimilation method showing advantages in many numerical experiments, is deficient when used in approximating covariance from an ensemble of small size. Implicit localization is used to add distance-related weight to covariance and filter spurious correlations which weaken the EnKF’s capability to estimate uncertainty correctly. The effect of this kind of localization is studied in two-dimensional (2D) and three-dimensional (3D) synthetic cases. It is found that EnKF with localization can capture reliably both the mean and variance of the hydraulic conductivity field with higher efficiency; it can also greatly stabilize the assimilation process as a small-size ensemble is used. Sensitivity experiments are conducted to explore the effect of localization function format and filter lengths. It is suggested that too long or too short filter lengths will prevent implicit localization from modifying the covariance appropriately. Steep localization functions will greatly disturb local dynamics like the 0-1 function even if the function is continuous; four relatively gentle localization functions succeed in avoiding obvious disturbance to the system and improve estimation. As the degree of localization of the L function increases, the parameter sensitivity becomes weak, making parameter selection easier, but more information may be lost in the assimilation process. Le filtre de Kalman d’ensemble (EnKF), une méthode efficace de traitement des données présentant des avantages dans de nombreux cas numériques, est déficiente quand elle est utilisée pour estimer la covariance d’un ensemble de petite taille. La localisation implicite est utilisée pour ajouter le poids pondéré de la distance à la covariance et pour filtrer les corrélations erronées qui affaiblissent la capacité du EnKF à estimer l’incertitude correctement. L’effet de ce type de localisation est étudié dans des cas synthétiques bi et tri-dimensionnels. On trouve que le EnKF avec localisation peut approcher de façon fiable à la fois la moyenne et la variance de la conductivité hydraulique avec une efficacité plus grande; il peut aussi grandement stabiliser le processus de traitement quand un ensemble de petite dimension est considéré. Des expériences de sensibilité ont été conduites pour explorer l’effet du format de la fonction localisation et longueur de filtre. On suggère que des longueurs de filtre trop grandes ou trop petites empêcheront à la localisation implicite de modifier la covariance de façon appropriée. Des fonctions de localisation raides telle la fonction 0-1 perturberont grandement la dynamique locale même si la fonction est continue; quatre fonctions de localisation relativement douces réussissent à éviter les perturbations évidentes du système et améliorent l’estimation. Lorsque le degré de localisation de la fonction L s’accroît, le paramètre sensibilité devient faible, rendant la sélection des paramètres plus aisée, mais d‘avantage d’informations peuvent être perdues dans le processus de traitement. El conjunto del filtro de Kalman (EnKF), un método eficiente de asimilación de datos que muestra ventajas en muchos experimentos numéricos, es deficiente cuando es usado en la aproximación de la covarianza a partir de un conjunto de pequeños tamaños. Se usa la localización implícita para sumar el peso relacionado con la covarianza y a las correlaciones espurias que debilitan la capacidad EnKF’s para estimar correctamente la incerteza. Se estudia este tipo de localización en casos sintéticos bi y tridimensional. Se encuentra que EnKF con localización puede capturar confiablemente tanto el promedio como la varianza del campo de conductividad hidráulica con una mayor, puede también estabilizar grandemente el proceso de asimilación cuando se usa un conjunto de pequeño tamaño. Se llevan a cabo experimentos de sensibilidad para explorar el efecto del formato de la función de la localización y la longitud de los filtros. Se s

Photon Localization in Resonant Media  

NASA Astrophysics Data System (ADS)

Unlike electrons that can be trapped by the Coulomb interaction at atomic sites, photons are not bound by individual particles. They may, however, be strongly scattered at Mie resonances, with the scattering cross section considerably exceeding the geometric cross section. We utilize Mie resonances to localize microwave radiation in low-density quasi-one dimensional samples of randomly positioned dielectric spheres. We explore factors that facilitate photon localization and probe the properties of localized waves. Sharp dips in the ensemble average of transmission and peaks in the average photon transit time are found near the first five Mie resonances. A decisive statistical test of photon localization, based on measurements of the variance of the intensity normalized by its ensemble average value, shows, however, that localization occurs only in a narrow window above the first Mie resonance. Measurements of this localization parameter are compared to measurements of the dimensionless conductance and of the Thouless number in samples with and without absorption. The Thouless number, which is the ratio of the width to the spacing of quasi-modes of a random medium, is obtained from measurements of the field correlation function with frequency shift and of the spacing between resonances in a sealed cavity. In samples with negligible absorption, these parameters coincide. The localization parameters reach a minimum within the window of localization as a result of collective scattering. In the presence of absorption, only the variance of intensity remains a reliable guide to localization. When the sample is cooled to 77 K to reduce absorption, narrow Lorentzian transmission peaks are observed as a result of resonant tunneling through long-lived localized modes. The enhancement of intensity in long-lived modes as the localization threshold is approached is related to sharp line lasing in random amplifying media. In collaboration with Andrey Chabanov.

STRAIN LOCALIZATION IN IRRADIATED MATERIALS  

SciTech Connect

Low temperature irradiation can significantly harden metallic materials and often lead to strain localization and ductility loss in deformation. This paper provides a review on the radiation effects on the deformation of metallic materials, focusing on microscopic and macroscopic strain localization phenomena. The microscopic strain localization often observed in irradiated materials are dislocation channeling and deformation twinning, in which dislocation glides are evenly distributed and well confined in the narrow bands, usually a fraction of a micron wide. Dislocation channeling is a common strain localization mechanism observed virtually in all irradiated metallic materials with ductility, while deformation twinning is an alternative localization mechanism occurring only in low stacking fault energy materials. In some high stacking fault energy materials where cross slip is easy, curved and widening channels can be formed depending on dose and stress state. Irradiation also prompts macroscopic strain localization (or plastic instability). It is shown that the plastic instability stress and true fracture stress are nearly independent of irradiation dose if there is no radiation-induced phase change or embrittlement. A newly proposed plastic instability criterion is that the metals after irradiation show necking at yield when the yield stress exceeds the dose-independent plastic instability stress. There is no evident relationship between the microscopic and macroscopic strain localizations; which is explained by the long-range back-stress hardening. It is proposed that the microscopic strain localization is a generalized phenomenon occurring at high stress.

Localization scheme for relativistic spinors  

NASA Astrophysics Data System (ADS)

A new method to determine localized complex-valued one-electron functions in the occupied space is presented. The approach allows the calculation of localized orbitals regardless of their structure and of the entries in the spinor coefficient matrix, i.e., one-, two-, and four-component Kramers-restricted or unrestricted one-electron functions with real or complex expansion coefficients. The method is applicable to localization schemes that maximize (or minimize) a functional of the occupied spinors and that use a localization operator for which a matrix representation is available. The approach relies on the approximate joint diagonalization (AJD) of several Hermitian (symmetric) matrices which is utilized in electronic signal processing. The use of AJD in this approach has the advantage that it allows a reformulation of the localization criterion on an iterative 2 × 2 pair rotating basis in an analytical closed form which has not yet been described in the literature for multi-component (complex-valued) spinors. For the one-component case, the approach delivers the same Foster-Boys or Pipek-Mezey localized orbitals that one obtains from standard quantum chemical software, whereas in the multi-component case complex-valued spinors satisfying the selected localization criterion are obtained. These localized spinors allow the formulation of local correlation methods in a multi-component relativistic framework, which was not yet available. As an example, several heavy and super-heavy element systems are calculated using a Kramers-restricted self-consistent field and relativistic two-component pseudopotentials in order to investigate the effect of spin-orbit coupling on localization.

Primary Localized Cutaneous Nodular Amyloidosis Following Local Trauma  

PubMed Central

Primary localized cutaneous nodular amyloidosis (nodular amyloidosis) is a rare and distinct type of amyloidosis, in which amyloid L deposition is limited to the skin and typically manifested as a tumefactive nodule on the acral sites. However, the definite cause of nodular amyloidosis is still unknown. Although it is relatively well known that the amyloid deposits in nodular amyloidosis originate from immunoglobulin light chains secreted by local plasma cells, traumatic injury to the skin has rarely been recognized as a triggering factor of nodular amyloidosis. Herein, we present a case of a 50-year-old male patient with primary localized cutaneous nodular amyloidosis, which occurred after local trauma, and discuss the relationship between traumatic damage and dermal amyloid L deposition.

Localized defect modes in graphene  

NASA Astrophysics Data System (ADS)

We study the properties of localized vibrational modes associated with structural defects in a sheet of graphene. For the examples of the Stone-Wales defects, one- and two-atom vacancies, many-atom linear vacancies, and adatoms in a honeycomb lattice, we demonstrate that the local defect modes are characterized by stable oscillations with the frequencies lying outside the linear frequency bands of an ideal graphene. In the frequency spectral density of thermal oscillations, such localized defect modes lead to the additional peaks from the right side of the frequency band of the ideal sheet of graphene, which indicate the presence of defects in the graphene flakes.

Phantom tektite localities of Borneo  

NASA Astrophysics Data System (ADS)

An attempt to find out more about tektite finds at Riam, Indonesian Borneo (Kalimantan), has uncovered a long-standing and complicated confusion about tektite localities in the southern portion of Borneo. It appears that the only authentic localities in the whole of Indonesian Borneo are at Martapura, Pelaihari, and the Sungei (River) Riam Kanan, all within 40 km of each other in the southeastern corner of the island, and all documented, mainly in Dutch and German works, by the early 20th century. Other localities mentioned and shown on maps in more recent French and English publications are mere phantoms resulting from a succession of misinterpretations of previous literature.

The Local Bubble: an update  

NASA Astrophysics Data System (ADS)

Our view of the the Sun's near neighbourhood in space, the "Local Bubble" region, has changed dramatically over the past decade. The interstellar gas inside this rarefied Cavity is character-ized by a surprisingly wide range of temperatures (100K -1,000,000K), densities, and diffuse structures that are all contained within a 150pc diameter region of space whose fragmented neutral boundary has recently been mapped in 3-D. Rather surprisingly, doubts have even been cast on whether the Local Bubble cavity is filled with a hot million degree emitting gas and, much to the bewilderment of many astrophysicists, we still do not know which physical processes are responsible for the observed ionization state of the local interstellar plasma. This short talk will discuss the latest observational results from several recent studies of the Local Bubble region and how current theoretical models seem at odds with empirical evidence.

Localization precision of stochastic optical localization nanoscopy using single frames.  

PubMed

ABSTRACT. The Cramer-Rao lower bound (CRLB) on localization precision of unbiased estimators is analyzed for stochastic optical localization nanoscopy that localizes emitters frame by frame independently. It is found that the CRLB is a function of the mean number of detected photons per emitter, signal to Poisson noise ratio, signal to Gaussian noise ratio, point spread function (PSF), pixel size, and relationship of emitter locations. With a slight and practical approximation, effect of Gaussian noise is equivalent to increasing the mean photon count of Poisson noise by a number equal to the variance of Gaussian noise. Numerical examples demonstrate that the CRLB of emitters located on a curve increase fast as the distance of adjacent emitters increases. The mean CRLB of randomly uniformly distributed emitters in both two-dimensional and three-dimensional imaging increases exponentially fast as the emitter density increases. The effects of PSF, standard deviation of PSF, mean number of detected photons per emitter, signal to noise ratio, axial thickness, and pixel size on the CRLB are also numerically investigated. The analytical and numerical results provide a guideline for the design of location estimators and a benchmark for the achievable localization precision of stochastic optical localization nanoscopy.

De las observaciones realizadas se concluye: 1) El número promedio de moléculas de OH en la coma durante 37 días de observación fue de (8.9±3.5)x1034 moléculas, lo que implica una tasa de producción promedio de OH de 1.8x1029 moléculas seg-1 y consecuentemente una pérdida de masa promedio de 17±6 toneladas seg-1 . Este valor está de acuerdo con las mediciones realizadas por las sondas Vega y Giotto. 2) El monitoreo desde el lAR revela la existencia de variaciones bruscas en los flujos de absorción del OH. Estas variaciones son consistentes con los modelos que representan la producción gaseosa a partir de ejecciones y/o desprendimientos discretos de materia congelada del núcleo. 3) Las variaciones en la densidad de flujo son consistentes con las estimaciones de los tiem- pos de vida medios del H2O y del OH en presencia del campo de radiación solar. 4) Se encuentra una correlación entre la intensidad del flujo absorbido y anisotropías en Ia dinamica de la coma.

Localization and quantitative co-localization of enamelin with amelogenin.  

PubMed

Enamelin and amelogenin are vital proteins in enamel formation. The cooperative function of these two proteins controls crystal nucleation and morphology in vitro. We quantitatively analyzed the co-localization between enamelin and amelogenin by confocal microscopy and using two antibodies, one raised against a sequence in the porcine 32kDa enamelin region and the other raised against full-length recombinant mouse amelogenin. We further investigated the interaction of the porcine 32kDa enamelin and recombinant amelogenin using immuno-gold labeling. This study reports the quantitative co-localization results for postnatal days 1-8 mandibular mouse molars. We show that amelogenin and enamelin are secreted into the extracellular matrix on the cuspal slopes of the molars at day 1 and that secretion continues to at least day 8. Quantitative co-localization analysis (QCA) was performed in several different configurations using large (45?m height, 33?m width) and small (7?m diameter) regions of interest to elucidate any patterns. Co-localization patterns in day 8 samples revealed that enamelin and amelogenin co-localize near the secretory face of the ameloblasts and appear to be secreted approximately in a 1:1 ratio. The degree of co-localization decreases as the enamel matures, both along the secretory face of ameloblasts and throughout the entire thickness of the enamel. Immuno-reactivity against enamelin is concentrated along the secretory face of ameloblasts, supporting the theory that this protein together with amelogenin is intimately involved in mineral induction at the beginning of enamel formation.

[Informationization policies of local governments].  

PubMed

In line with the rapid progress in technical innovation, the wave of informationization is now reaching every aspect of Japanese society. With the explosive spread of the Internet, local governments are implementing administrative policies to facilitate the construction of information network systems which will help promote the spread of information at the local level. The Ministry of Posts and Telecommunications, the Ministry of International Trade and Industry, and other organizations of the Japanese government are also implemending a variety of measures to assist these moves on the part of local governments. A look at administrative services for local residents reveals a great need for the proliferation of information within the areas of welfare and medical care; in particular, counselling concerning nursing care and medical services in remote areas are needed. In order to realize new measures promoting informationization, however, the cooperation and understanding of local governors or mayors are essential. Because these people are very busy, short video and computer graphic presentations should be prepared in order to make the greatest impact in the least amount of time. PMID:10412147

We shall analyze the conditions for consistent propagation of closed strings in locally anisotropic background spaces.

``Campo del Cielo'' Meteorites: Astronomical Heritage and Cultural Colonialism  

NASA Astrophysics Data System (ADS)

In the province of Chaco, Argentina, there is a very unique dispersion of metallic meteorites called ``Campo del Cielo''. One of the meteoric fragments of this dispersion, the meteorite called ``El Chaco'', consisting of 37 tons, is the second heaviest in the world. These meteorites are of great importance to the worldview of the Moqoit, aboriginal people that inhabit this region. For the local Creole population the meteorites are also relevant, that's why they have being cited in numerous documents and reports since the colonial period. During the first months of 2012, two Argentine artists and the Artistic Director of the German contemporary art exhibition called dOCUMENTA (13) tried to move ``El Chaco'' meteorite to Germany in order to exhibit it as an artistic object. Due to the fact that moving the meteorite could have a negative impact according to the Moqoit cosmology and that they were not able to participate in the decision they begun a manifestation against the movement of El Chaco. The opposition made by aboriginal communities and experts in cultural astronomy was able to stop the transfer. The whole process and its impact on the local community have promoted a deep discussion about art, science and cultural colonialism. In this paper we aim to address this debate and its consequences. This will allow us to think about contemporary forms of colonialism that are hidden in many scientific and artistic projects. Furthermore, we aim to debate about the most effective ways of protecting astronomical heritage in the Third World.

The salih ataxia mutation impairs rubicon endosomal localization.  

PubMed

We previously described a new form of recessive ataxia, Salih ataxia, in a large consanguineous Saudi Arabian family with three affected children carrying a new identified mutation in the KIAA0226 gene (c.2624delC; p.Ala875ValfsX146) coding for Rubicon. The pathogenicity of such mutation remains to be identified. Hence, we address the cellular impact of Rubicon p.Ala875ValfsX146 on endosomal/lysosomal machinery on cultured cells. We confirm that Rubicon colocalizes with the late endosome marker Rab7 and demonstrate that it also colocalizes with LampI at lysosomes. The Salih ataxia mutation leads to a diffuse cytosolic distribution and mislocalized protein from the late endosomes, indicating that deletion of the diacylglycerol binding-like motif in the mutant protein interferes with normal Rubicon subcellular localization and confirming the pathogenicity of the mutation.

Accidental hypothermia and localized cold injuries remain a significant public health problem. The deleterious effect of cold exposure on human performance and health has been documented for centuries. Some of the earliest descriptions came from Baron de Larrey, Napoleon's chief surgeon. During the disastrous invasion of Russia in 1812 he depicted the mental and physical hardships endured by the French

Local journals for international research?  

NASA Astrophysics Data System (ADS)

The above question may sound a little anomalous, after all, isn't it obvious that “international” scientific research should be published in international journals? The logic of such an argument, however, may not be as self-evident as it would seem, particularly if we define “international” research as that research done in cooperation with colleagues from abroad or in countries other than our own.Scientists often feel pressure to publish their work in journals that have wide circulation, thus promoting their work in order to get support for additional proposals. Yet I believe that a case can still be made for publishing a part of an international work in an appropriate local journal. I am not suggesting a proliferation of the literature by publishing a translation or republishing a paper. However, I believe there are many facets to each research program and that papers meeting the high quality standards of international journals may also be appropriate for local journals. Each research program and each paper should be considered on its own merits. Reasons an author may choose to publish in a local journal include reaching a more appropriate audience, presenting a topic that may be covered frequently in international journals but neglected in local ones, and exposing the work in a language other than English.

Local flicker stimulation evokes local retinal blood velocity changes.  

PubMed

We investigated the effect of localized visual stimulation on human retinal blood velocity using an adaptive optics scanning laser ophthalmoscope (AOSLO). To measure the blood velocity response, the AOSLO scanning raster was moved over the target arteries and red blood cell velocity was measured. Localized visual stimuli were delivered by projecting flicker patterns inside or outside the target artery's downstream region. The blood velocity increased in the presence of a flicker stimulus in the downstream region but not when outside the downstream region. The blood velocity increased more with larger area of stimulation. This increase was significant even when the stimulus was smaller than 600 ?m × 600 ?m. These findings suggest that when the retina regulates its blood flow to metabolic demands, it regulates blood velocity in the vascular system selectively, according to activity of neurons within its field of influence.

Sacroplasty for Local or Massive Localization of Multiple Myeloma  

SciTech Connect

The purpose of this study was to assess the efficacy of cementoplasty in the treatment of sacral multiple myelomas. We retrospectively reviewed the records of eight patients (four women and four men; age range 47-68 years; mean age 57.8) who underwent cementoplasty for painful osteolytic localization of multiple myeloma between April 2007 and May 2009. The patients had difficulty walking because of increasing pain. Six patients had persistent pain despite other cementoplasties for vertebral and femoral localization, whereas two patients referred at the time of diagnosis had only sacral lesions. The clinical indication for treatment was (1) a pain intensity score {>=}5 on visual analogue scale (VAS) and (2) pain totally or partially refractory to analgesic treatment in patients with a life expectancy >3 months. Technical planning was based on computed tomography and/or magnetic resonance imaging. Six patients had previously undergone radiotherapy or chemotherapy and were receiving varying doses of analgesics, whereas sacroplasty represented the first treatment for two patients. Five patients had monolateral local involvement, and the other patients had massive involvement of the sacrum; Technical success was achieved in all cases. We had only one small and asymptomatic foraminal leak. All patients experienced improvement in symptoms after the procedure, as demonstrated by improved VAS scores and performance status (PS) and decreased analgesic dose constant during follow-up. In our experience, percutaneous stabilization can be used effectively and safely in patients with focal or extensive involvement of the sacrum by multiple myeloma.

Ear localization using hierarchical clustering  

NASA Astrophysics Data System (ADS)

Ear biometrics has been found to be a good and reliable technique for human recognition. With the initial doubts on uniqueness of the ear, ear biometrics could not attract much attention. But after it has been said that it is almost impossible to find two ears with all the parts identical, ear biometrics has gained its pace. To automate the ear based recognition process, ear in the image is required to be localized automatically. This paper presents a technique for the same. Ear localization in the proposed technique is carried out by using the hierarchical clustering of the edges obtained from the side face image. The technique is tested on a database consisting of 500 side face images of human faces collected at IIT Kanpur. It is found to be giving 94.6% accuracy.

Ecological genomics of local adaptation.

It is increasingly important to improve our understanding of the genetic basis of local adaptation because of its relevance to climate change, crop and animal production, and conservation of genetic resources. Phenotypic patterns that are generated by spatially varying selection have long been observed, and both genetic mapping and field experiments provided initial insights into the genetic architecture of adaptive traits. Genomic tools are now allowing genome-wide studies, and recent theoretical advances can help to design research strategies that combine genomics and field experiments to examine the genetics of local adaptation. These advances are also allowing research in non-model species, the adaptation patterns of which may differ from those of traditional model species. PMID:24136507

Local fluctuations in solution mixtures  

NASA Astrophysics Data System (ADS)

An extension of the traditional Kirkwood-Buff (KB) theory of solutions is outlined which provides additional fluctuating quantities that can be used to characterize and probe the behavior of solution mixtures. Particle-energy and energy-energy fluctuations for local regions of any multicomponent solution are expressed in terms of experimentally obtainable quantities, thereby supplementing the usual particle-particle fluctuations provided by the established KB inversion approach. The expressions are then used to analyze experimental data for pure water over a range of temperatures and pressures, a variety of pure liquids, and three binary solution mixtures - methanol and water, benzene and methanol, and aqueous sodium chloride. In addition to providing information on local properties of solutions it is argued that the particle-energy and energy-energy fluctuations can also be used to test and refine solute and solvent force fields for use in computer simulation studies.

[Cardiac arrest and local anaesthetics].  

PubMed

Local anaesthetics may induce cardiac arrest, usually because of rapid absorption from the site of injection or because of an intended intravascular injection. Early central nervous system symptoms usually precede seizures. Cardiac arrhythmias follow the CNS signs. These arrhythmias often resolve with the i.v. bolus injection of 100 to 150mL of a lipid emulsion (20% Intralipid(®)). Although long acting local anaesthetics (bupivacaine, ropivacaine, levobupivacaine) are predominantly involved in this cardiac toxicity, lidocaine may also induce cardiac arrhythmias and clinician must be aware of this risk. In case of cardiac arrest, resuscitation manoeuvres are of major importance. They need to be performed immediately and the efficacy of the lipid rescue requires a correct coronary flow to be efficacious. Finally, prevention is the key of a safe injection. It is important to control the dose, to inject slowly, without any excessive pressure and to verify that no blood reflux occurs. PMID:22704068

Insulinoma: pathophysiology, localization and management  

PubMed Central

Insulinoma is a rare neuroendocrine tumor that causes oversecretion of insulin and, as a result, patients present with symptoms of hypoglycemia. Fortunately, insulinomas are usually benign and solitary, and surgical cure rates are highly favorable. Most of these tumors occur sporadically, but they can also be associated with multiple endocrine neoplasia type-1 syndrome. The diagnosis is confirmed by a supervised fast, and early detection is important. Several preoperative and intraoperative techniques with various success rates have been employed in order to localize the lesion. When technically feasible, tumor enucleation is the procedure of choice; however, a more formal resection may be necessary for certain tumors. In the age of laparoscopy, the role of laparoscopic surgery in the management of insulinomas is continuing to attract attention. This review will discuss the historical background, pathogenesis, diagnosis, localization and management of insulinomas.

Working within local funding trends.  

PubMed

Like politics, environmentalism, and fashion, there are trends in health care research and funding. According to a series of reports by the Foundation Center-which collects, organizes, and communicates information on U.S. philanthropy-it is important to understand the significant financial and programmatic changes in the way foundations give. For pharmacists considering soliciting grant support, it is critical that they become aware of these trends and be responsive to the local or regional environments that affect funding. PMID:16553471

Exploiting Relaxation in Local Search

Branch-and-bound uses relaxation to prune search trees but sometimes scales poorly to large problems. Conversely, local search often scales well but may be unable to nd optimal solutions, perhaps because it does not exploit relaxation. Both phenomena occur in the construction of low-autocorrelation binary sequences, a problem arising in communi- cation engineering. This paper proposes a hybrid approach to optimiza-

Forest commons and local enforcement  

PubMed Central

This article examines the relationship between local enforcement and forests used as commons. It uses a unique multicountry dataset, created over the past 15 years by the International Forestry Resources and Institutions Research Program. Drawing on original enforcement and forest commons data from 9 countries, we find that higher levels of local enforcement have a strong and positive but complex relationship to the probability of forest regeneration. This relationship holds even when the influence of a number of other factors such as user group size, subsistence, and commercial importance of forests, size of forest, and collective action for forest improvement activities is taken into account. Although several of the above factors have a statistically significant relationship to changes in the condition of forest commons, differences in levels of local enforcement strongly moderate their link with forest commons outcomes. The research, using data from diverse political, social, and ecological contexts, shows both the importance of enforcement to forest commons and some of the limits of forest governance through commons arrangements.

Near-field auditory localization  

NASA Astrophysics Data System (ADS)

Although many researchers have examined auditory localization for relatively distant sound sources, very little is known about the spatial perception of sound sources near the head. A series of measurements and experiments have been performed to analyze auditory localization cues and localization performance in the near-field, defined as the region within 1 m of the head. First, a preliminary experiment compared four response methods that allowed subjects to indicate the perceived azimuth, elevation, and distance of a near-field source. The results indicate that a direct-location response, in which the subject simply moves a pointer to the perceived location of the source, is the most accurate response method even when the source is outside the visual field. Next, near-field head related transfer functions (HRTFs) were calculated using a rigid-sphere model of the head and measured using an acoustic manikin and a point source. The resulting HRTFs show that the interaural intensity difference (IID) increases dramatically as a lateral source approaches the head, while the interaural time delay (ITD) is roughly independent of distance. The HRTFs also suggest a possible low-pass spectral distance cue for nearby sources, but failed to show a strong distance-dependence in high-frequency pinna-based elevation cues. Finally, a series of psychoacoustic experiments were performed to evaluate cues. Finally, a series of psychoacoustic experiments were performed to evaluate near-field localization performance. An experiment with a broadband source showed that the overall directional error in the near field (17o) was comparable to previously measured errors in far-field localization. Distance perception accuracy was strongly dependent on azimuth, with the stimulus-response correlation ranging from less than 0.4 in the median plane to 0.85 to the side. Additional experiments showed that distance perception is degraded substantially when listening monaurally or when the stimulus does not contain low-frequency (<3000 Hz) energy. The results of the psychoacoustic experiments demonstrate that listeners are able to make reasonably accurate judgments about the distance of nearby sources, and suggest that these judgments are largely based on distant-dependent changes in the low-frequency IID.

Indoor localization using magnetic fields  

NASA Astrophysics Data System (ADS)

Indoor localization consists of locating oneself inside new buildings. GPS does not work indoors due to multipath reflection and signal blockage. WiFi based systems assume ubiquitous availability and infrastructure based systems require expensive installations, hence making indoor localization an open problem. This dissertation consists of solving the problem of indoor localization by thoroughly exploiting the indoor ambient magnetic fields comprising mainly of disturbances termed as anomalies in the Earth's magnetic field caused by pillars, doors and elevators in hallways which are ferromagnetic in nature. By observing uniqueness in magnetic signatures collected from different campus buildings, the work presents the identification of landmarks and guideposts from these signatures and further develops magnetic maps of buildings - all of which can be used to locate and navigate people indoors. To understand the reason behind these anomalies, first a comparison between the measured and model generated Earth's magnetic field is made, verifying the presence of a constant field without any disturbances. Then by modeling the magnetic field behavior of different pillars such as steel reinforced concrete, solid steel, and other structures like doors and elevators, the interaction of the Earth's field with the ferromagnetic fields is described thereby explaining the causes of the uniqueness in the signatures that comprise these disturbances. Next, by employing the dynamic time warping algorithm to account for time differences in signatures obtained from users walking at different speeds, an indoor localization application capable of classifying locations using the magnetic signatures is developed solely on the smart phone. The application required users to walk short distances of 3-6 m anywhere in hallway to be located with accuracies of 80-99%. The classification framework was further validated with over 90% accuracies using model generated magnetic signatures representing hallways with different kinds of pillars, doors and elevators. All in all, this dissertation contributes the following: 1) provides a framework for understanding the presence of ambient magnetic fields indoors and utilizing them to solve the indoor localization problem; 2) develops an application that is independent of the user and the smart phones and 3) requires no other infrastructure since it is deployed on a device that encapsulates the sensing, computing and inferring functionalities, thereby making it a novel contribution to the mobile and pervasive computing domain.

Andrea del Sarto rehabilitated: a psychoanalytic emendation.  

PubMed

Ernest Jones's "The Influence of Andrea del Sarto's Wife on His Art" (1913) is an early example of psychoanalysis applied to the study of a prominent painter. Greatly influenced by Freud's Leonardo da Vinci and a Memory of His Childhood, Jones gave excessive credence to Vasari's highly prejudicial account of the life of del Sarto, on which the study relied heavily. Jones attempted to account psychologically for the circumstance that del Sarto, though highly skilled and "faultless," was not the equal of the three preeminent masters of the Italian High Renaissance: Leonardo, Michelangelo, and Raphael. Jones's uncritical acceptance of the Vasari biography encouraged him to view Sarto's assumed deficiency as the result of excessive attachment to his wife, a pathological uxoriousness. A contemporary psychoanalytic perspective, with its emphasis on the emotive response of the analyst, requires us to pay attention to the evocative nature of the work of the artist, an approach Jones neglected. In an examination of several paintings, the artist's sensitivity to the position of the spectator is explored, as is the interest in involving the viewer spatially and emotionally. An appreciation for the viewer's position is consistent with a capacity for using projected internal objects for creative purposes. The presence of this capacity suggests a revised view of del Sarto's contribution to art and of his relationship with his wife. PMID:12580329

We focus on the nonlocality concerning local copying and local discrimination, especially for a set of orthogonal maximally entangled states in any prime dimensional system, as a study of nonlocality of a set of states. As a result, for such a set, we completely characterize deterministic local copiability and show that local copying is more difficult than local discrimination.

Problems in local emergency management  

NASA Astrophysics Data System (ADS)

Local governments (county and city) take the most active role in responding to natural and manmade disasters, yet very little is understood about the role of the emergency manager-the administrator who organizes and coordinates the emergency response of a community. This article describes the more common organizational niches that emergency managers are placed into, and it examines some of the political, institutional, and budgetary constraints that hinder the emergency manager's operations. Finally, it suggests strategies for solving these problems and identifies areas for further research.

Using (240)Pu hot fission as an example, we discuss the identification of the fragments and the calculation of their kinetic, excitation, and interaction energies, through the localization of the orbital wave functions. We show that the disentanglement of the fragment wave functions is essential to the quantum-mechanical definition of scission and the calculation of physical observables. Finally, we discuss the fragments' prescission excitation mechanisms and give a nonadiabatic description of their evolution beyond scission. PMID:22026846

Local Observation in Eternal Inflation  

NASA Astrophysics Data System (ADS)

We consider landscape models that admit several regions where the conditions for eternal inflation hold. It is shown that one can use the no-boundary wave function to calculate small departures from homogeneity within our past light cone despite the possibility of much larger fluctuations on super horizon scales. The dominant contribution comes from the history exiting eternal inflation at the lowest value of the potential. In a class of landscape models this predicts a tensor to scalar ratio of about 10%. In this way the no-boundary wave function defines a measure for the prediction of local cosmological observations.

On local isodynamicity in tokamaks

It is shown that local isodynamicity (i.e., the constancy of the absolute value of the magnetic field on a magnetic surface) can take place at the periphery of the tokamak near the separatrix with an internal X point. An isodynamic layer including several magnetic surfaces cannot exist in a tokamak because the safety factor q is too low and the shape of the surfaces is predetermined. The layered and global isodynamicity is possible in pinches with low values of q (Palumbo's configuration).

Robust multiplatform RF emitter localization  

NASA Astrophysics Data System (ADS)

In recent years, position based services has increase. Thus, recent developments in communications and RF technology have enabled system concept formulations and designs for low-cost radar systems using state-of-the-art software radio modules. This research is done to investigate a novel multi-platform RF emitter localization technique denoted as Position-Adaptive RF Direction Finding (PADF). The formulation is based on the investigation of iterative path-loss (i.e., Path Loss Exponent, or PLE) metrics estimates that are measured across multiple platforms in order to autonomously adapt (i.e. self-adjust) of the location of each distributed/cooperative platform. Experiments conducted at the Air-Force Research laboratory (AFRL) indicate that this position-adaptive approach exhibits potential for accurate emitter localization in challenging embedded multipath environments such as in urban environments. The focus of this paper is on the robustness of the distributed approach to RF-based location tracking. In order to localize the transmitter, we use the Received Signal Strength Indicator (RSSI) data to approximate distance from the transmitter to the revolving receivers. We provide an algorithm for on-line estimation of the Path Loss Exponent (PLE) that is used in modeling the distance based on Received Signal Strength (RSS) measurements. The emitter position estimation is calculated based on surrounding sensors RSS values using Least-Square Estimation (LSE). The PADF has been tested on a number of different configurations in the laboratory via the design and implementation of four IRIS wireless sensor nodes as receivers and one hidden sensor as a transmitter during the localization phase. The robustness of detecting the transmitters position is initiated by getting the RSSI data through experiments and then data manipulation in MATLAB will determine the robustness of each node and ultimately that of each configuration. The parameters that are used in the functions are the median values of RSSI and rms values. From the result it is determined which configurations possess high robustness. High values obtained from the robustness function indicate high robustness, while low values indicate lower robustness.

Local area networks for radiology.  

PubMed

This article is a tutorial on local area networks (LAN) for radiology applications. LANs are being implemented in radiology departments for the management of text and images, replacing the inflexible point-to-point wiring between two devices (computer-to-terminal). These networks enable the sharing of computers and computer devices, reduce equipment costs, and provide improved reliability. Any LAN must include items from the following four categories: transmission medium, topology, data transmission mode, and access protocol. Media for local area networks are twisted pair, coaxial, and optical fiber cables. The topology of these networks include the star, ring, bus, tree, and circuit-switching. Data transmission modes are either analog signals or digital signals. Access protocol methods include the broadcast bus system and the ring system. A performance measurement for a LAN is the throughput rate as a function of the number of active computer nodes. Standards for LANs help to ensure that products purchased from multiple manufacturers will operate successfully. PMID:3154655

Severe Local Storms Cultural Heritage  

NASA Astrophysics Data System (ADS)

Local storms always had a deep impact on people communities, mainly because of the severe damage caused, because of their unpredictability and, up to a few years ago, even because of the lack of knowledge and awareness on their physical origin. Because of this large impact on real life and on imagination, people needed and wanted to describe and report the occurrence of these events, giving them suited names. Often, these nouns are related to the myth developed to explain the cause of the events. In this work, a short presentation and description of the popular nouns used to describe severe local storm events in different areas of the World is given. Countries taken into account span from Italy, moving toward Africa and reaching a few communities of Native Americans. The etymology of the names gives interesting information, useful even under the anthropological point of view, on the Culture and Believes of the peoples who adopted them. This research work is the result of an underground activity carried out in the last ten years by the authors, during their contacts with students and researchers coming from different Countries and mainly met at the International Center for Theoretical Physics in Trieste.

Localized urethral cancer in women  

SciTech Connect

The results of treatments for localized carcinoma of the urethra were assessed in 21 consecutive women treated at our institutions over a twenty year period. Only one of the tumors was confined to the distal urethra. Eighty-six percent invaded the periurethral tissues and 24% were known to be associated with regional lymph node metastases. Fifty-seven percent were adenocarcinomas. Five patients refused active therapeutic intervention and expired within one to 30 months following diagnosis. Sixteen patients were treated with extirpative surgery, radiation therapy, or combinations of the two. Four are free of disease at one, four, eleven, and 15 years after treatment. Nine developed pelvic recurrences, two developed pelvic recurrences and distant metastases and one developed distant metastases only from six to 72 months (mean, 19 months) after initial treatment. Eight of these 12 patients died at two to 13 months (mean, 8 months) after secondary treatment, two are alive with residual pelvic tumor, and two are clinically free of disease at 7 and 48 months. Only six patients were known to have distant metastases at the time of death and five of these six had adenocarcinomas. Advanced localized urethral cancer in women is difficult to eradicate and usually fatal.

Local Effects of Delayed Food  

PubMed Central

Five pigeons were trained on a procedure in which seven concurrent variable-interval schedules arranged seven different food–rate ratios in random sequence in each session. Each of these components lasted for 10 response-produced food deliveries, and components were separated by 10-s blackouts. We varied delays to food (signaled by blackout) between the two response alternatives in an experiment with three phases: In Phase 1, the delay on one alternative was 0?s, and the other was varied between 0 and 8?s; in Phase 2, both delays were equal and were varied from 0 to 4?s; in Phase 3, the two delays summed to 8?s, and each was varied from 1 to 7?s. The results showed that increasing delay affected local choice, measured by a pulse in preference, in the same way as decreasing magnitude, but we found also that increasing the delay at the other alternative increased local preference. This result casts doubt on the traditional view that a reinforcer strengthens a response depending only on the reinforcer's value discounted by any response–reinforcer delay. The results suggest that food guides, rather than strengthens, behavior.

Local Properties of Monogenic Mappings  

NASA Astrophysics Data System (ADS)

The great importance of conformal mapping methods in complex analysis suggests to look for a suitable higher dimensional analogue in the context of quaternionic analysis. As in the complex case, a serious study of the geometric properties of generalized holomorphic functions (or monogenic functions) requires to consider at first the local behavior of such transformations. Since the usual definition of conformal mappings (in the classical sense) in higher dimensions applies only to the restricted set of Möbius transformations (Liouville's theorem), the main task is to understand at first if monogenic functions can still play a special role for other types of mappings, for instance, for quasi-conformal ones. In this contribution we concentrate particularly on the infinitesimal behavior for such class of transformations. Monogenic functions are considered at first as general quasi-conformal mappings. We give it a more precise meaning by pointing out that a monogenic function maps locally balls onto explicitly characterized ellipsoids and vice versa. Finally, together with the geometric interpretation of the hypercomplex derivative, dilatations and distortions of these mappings can be estimated. This includes the description of the interplay between the Jacobian determinant and the hypercomplex derivative of a monogenic function.

Cosmological perturbations on local systems  

SciTech Connect

We study the effect of cosmological expansion on orbits - galactic, planetary, or atomic - subject to an inverse-square force law. We obtain the laws of motion for gravitational or electrical interactions from general relativity - in particular, we find the gravitational field of a mass distribution in an expanding universe by applying perturbation theory to the Robertson-Walker metric. Cosmological expansion induces an (a'/a)r-vector force where a(t) is the cosmological scale factor. In a locally Newtonian framework, we show that the (a'/a)r-vector term represents the effect of a continuous distribution of cosmological material in Hubble flow, and that the total force on an object, due to the cosmological material plus the matter perturbation, can be represented as the negative gradient of a gravitational potential whose source is the material actually present. We also consider the effect on local dynamics of the cosmological constant. We calculate the perihelion precession of elliptical orbits due to the cosmological constant induced force, and work out generalizations to the rotation curve and virial relation applicable to clusters of galaxies.

Molecular insights into intracellular RNA localization  

PubMed Central

Localization of mRNAs to specific destinations within a cell or an embryo is important for local control of protein expression. mRNA localization is well-known to function in very large and polarized cells such as neurons, and to facilitate embryonic patterning during early development. However, recent genome-wide studies have revealed that mRNA localization is more widely utilized than previously thought to control gene expression. Not only can transcripts be localized asymmetrically within the cytoplasm, they are often also localized to symmetrically-distributed organelles. Recent genetic, cytological, and biochemical studies have begun to provide molecular insight into how cells select RNAs for transport, move them to specific destinations, and control their translation. This review will summarize recent insights into the mechanisms and function of RNA localization with a specific emphasis on molecular insights into each step in the mRNA localization process.

Tracer localization in intracerebral gliosarcoma  

SciTech Connect

The comparative localization properties of 5 radiopharmaceuticals which have been used to image primary brain tumors were investigated in a transplanted gliosarcoma in the Fisher 344 rat. Planar and SPECT images using pinhole collimation were used to investigate localization 2-4 times between 13d and 28d after transplant Imaging studies of intravenously administered Tl-201 Cl, Tc-99m-HMPAO, -MIBI, and -DTPA, and I-123 IMT were made in 70 rats. Localization properties were measured in unirradiated (n=39) and irradiated (n=31, 22.5 Gy to brain, 14 days after transplant) control and tumor-bearing rats. Ex vivo imaging and well cup measurements were made at sacrifice. MRI was used to define tumor border ROIs. Major observations include: (1) Tl, IMT, DTPA, and MIBI show increased uptake in tumor, with tumor-to-nontumor uptake ratios (tnt) from planar pinhole ROIs ranging from 1.3{plus_minus}.1 to 2.9{plus_minus}.7 between 13 and 28 d after transplant; HMPAO shows decreased activity in tumor with tnt ranging from 0.4-0.6{plus_minus}.1; (2) high resolution SPECT provides significantly greater discrimination between tumor and nontumor uptake: SPECT tnt=10.3{plus_minus}2{sub DTPA}, 3.0{plus_minus}.3{sub IMT}, 10.5{plus_minus}2{sub MIBI}, 5.6{plus_minus}2{sub TL} and 0.4{plus_minus}.1{sub HMPAO}; planar tnt=2.2{plus_minus}.4{sub DTPA}, 1.4{plus_minus}.1{sub IMT}, 1.9{plus_minus}.4{sub MIBI}, 2.1{plus_minus}.7{sub TL}, and 0.5{plus_minus}.1{sub HMPAO}; and (3) no significant differences in uptake are seen between irradiated, more slowly growing tumors and the unirradiated tumors, and maximum tnt contrast is observed at 21 d with all radiopharmaceuticals. The study shows Tc-99m DTPA and Tc-99m MIBI to have the highest selective uptake in irradiated and unirradiated growing tumor.

Probabilistic Non-Local Means  

NASA Astrophysics Data System (ADS)

In this paper, we propose a so-called probabilistic non-local means (PNLM) method for image denoising. Our main contributions are: 1) we point out defects of the weight function used in the classic NLM; 2) we successfully derive all theoretical statistics of patch-wise differences for Gaussian noise; and 3) we employ this prior information and formulate the probabilistic weights truly reflecting the similarity between two noisy patches. The probabilistic nature of the new weight function also provides a theoretical basis to choose thresholds rejecting dissimilar patches for fast computations. Our simulation results indicate the PNLM outperforms the classic NLM and many NLM recent variants in terms of peak signal noise ratio (PSNR) and structural similarity (SSIM) index. Encouraging improvements are also found when we replace the NLM weights with the probabilistic weights in tested NLM variants.

Acoustic localization of triggered lightning  

NASA Astrophysics Data System (ADS)

We use acoustic (3.3-500 Hz) arrays to locate local (<20 km) thunder produced by triggered lightning in the Magdalena Mountains of central New Mexico. The locations of the thunder sources are determined by the array back azimuth and the elapsed time since discharge of the lightning flash. We compare the acoustic source locations with those obtained by the Lightning Mapping Array (LMA) from Langmuir Laboratory, which is capable of accurately locating the lightning channels. To estimate the location accuracy of the acoustic array we performed Monte Carlo simulations and measured the distance (nearest neighbors) between acoustic and LMA sources. For close sources (<5 km) the mean nearest-neighbors distance was 185 m compared to 100 m predicted by the Monte Carlo analysis. For far distances (>6 km) the error increases to 800 m for the nearest neighbors and 650 m for the Monte Carlo analysis. This work shows that thunder sources can be accurately located using acoustic signals.

Radioimmune localization of occult carcinoma  

SciTech Connect

Patients with a rising serum carcinoembryonic antigen level and no clinical or roentgenographic evidence of recurrent or metastatic cancer present a treatment dilemma. Eleven such patients, 10 with a previously treated colorectal carcinoma and 1 with a previously treated breast carcinoma, received an injection of the anticarcinoembryonic antigen monoclonal antibody ZCE-025 labeled with the radioisotope indium 111. Nuclear scintigraphy was performed on days 3 and 5 through 7 to detect potential sites of tumor recurrence. The monoclonal antibody scan accurately predicted the presence or absence of occult malignancy in 7 (64%) patients. Second-look laparotomy confirmed the monoclonal antibody scan results in the patients with colorectal cancer, and magnetic resonance imaging confirmed metastatic breast cancer. This study demonstrates that In-ZCE-025 can localize occult carcinoma and may assist the surgeon in facilitating the operative exploration. In-ZCE-025 assisted in the initiation of adjuvant therapy for the patient with breast cancer.

Mechanisms of heterochromatin subnuclear localization.  

PubMed

Transcriptionally repressed heterochromatin becomes the dominant form of chromatin in most terminally differentiated cells. Moreover, in most cells, at least one class of heterochromatin is positioned adjacent to the nuclear lamina. Recent approaches have addressed the mechanism of heterochromatin localization, in order to determine whether spatial segregation contributes to gene repression. Findings in worms and human cells confirm a role for histone H3K9 methylation in heterochromatin positioning, identifying a modification that is also necessary for gene repression of worm transgenic arrays. These pathways appear to be conserved, although mutations in mammalian cells have weaker effects, possibly due to redundancy in positioning mechanisms. We propose a general model in which perinuclear anchoring is linked to an epigenetic propagation of the heterochromatic state, through histone modification. PMID:23746617

Observer Localization in Multiverse Theories  

NASA Astrophysics Data System (ADS)

The progression of theories suggested for our world, from ego- to geo- to helio-centric models to universe and multiverse theories and beyond, shows one tendency: The size of the described worlds increases, with humans being expelled from their center to ever more remote and random locations. If pushed too far, a potential theory of everything (TOE) is actually more a theories of nothing (TON). Indeed such theories have already been developed. I show that including observer localization into such theories is necessary and su_cient to avoid this problem. I develop a quantitative recipe to identify TOEs and distinguish them from TONs and theories in-between. This precisely shows what the problem is with some recently suggested universal TOEs.

Localized surface plasmon resonance biosensors.  

PubMed

In this review, the most recent progress in the development of noble metal nano-optical sensors based on localized surface plasmon resonance (LSPR) spectroscopy is summarized. The sensing principle relies on the LSPR spectral shifts caused by the surrounding dielectric environmental change in a binding event. Nanosphere lithography, an inexpensive and simple nanofabrication technique, has been used to fabricate the nanoparticles as the LSPR sensing platforms. As an example of the biosensing applications, the LSPR detection for a biomarker of Alzheimer's disease, amyloid-derived diffusable ligands, in human brain extract and cerebrospinal fluid samples is highlighted. Furthermore, the LSPR sensing method can be modified easily and used in a variety of applications. More specifically, a LSPR chip capable of multiplex sensing, a combined electrochemical and LSPR protocol and a fabrication method of solution-phase nanotriangles are presented here. PMID:17716111

Weak localization of photon noise  

NASA Astrophysics Data System (ADS)

We present an experimental study of coherent backscattering (CBS) of photon noise from multiple scattering media. We use a pseudothermal light source with a microsecond coherence time to produce a noise spectrum covering a continuous transition, from wave fluctuations to shot noise over several MHz. The angle-dependent Fano factor of backscattered light shows an enhancement due to CBS in the wave fluctuation regime. The CBS line shape and enhancement factor of the noise power is consistent with theory in the weak-scattering limit and for a large number of open reflection channels. These initial experiments on weakly scattering media demonstrate that sensitive noise measurements can be combined with the separation of path lengths present in CBS, opening up new experiments on noise transport in the localization regime.

Preoperative localization of parathyroid adenomas  

SciTech Connect

During a 12-month period, 64 patients were operated on for primary hyperparathyroidism. Sixty-one had single adenomas and 3 had double adenomas. Preoperative imaging was used to localize the adenomas. Half of the patients (32 of 64) had magnetic resonance, thallium-201/technetium-99m subtraction scintigraphy, and high-resolution ultrasonography; the other 32 patients had 1 or 2 of the imaging modalities. Sensitivity and specificity of magnetic resonance imaging was 82 percent and 97 percent, respectively; the sensitivity and specificity of the other two modalities was 59 and 98 percent for subtraction scintigraphy and 73 and 98 percent for ultrasonography. The use of preoperative imaging facilitated surgical exploration, reduced operating time, and resulted in an increased number of successful operations. There were no negative explorations in this series as compared with 19 negative explorations (2.6 percent) in our prior experience with 720 operations.

Evaporación dinámica del cinturón de asteroides original  

NASA Astrophysics Data System (ADS)

Hemos integrado numéricamente un enjambre de 3000 partículas en la región del cinturón de asteroides, sujetas a las perturbaciones gravitatorias de Júpiter y Saturno. Al cabo de 107 años, se han formado ya todos los gaps de Kirkwood observados en el cinturón actual. El grupo en la resonancia 3/2 es, aunque en menor grado, también visible. Los tiempos de Lyapunov computados para los asteroides sobrevivientes, nos ha permitido encontrar la fracción de ellos que es capaz de sobrevivir por toda la edad del sistema solar, merced a la aplicacion de la relación empírica que vincula dichos tiempos al tiempo en el cual se manifiestan grandes transiciones orbitales. La fracción de supervivientes es de aproximadamente 1/100. El resto de la masa faltante en el cinturón, es atribuible a colisiones catastróficas con cometas en etapas primordiales.

F508del-CFTR increases intracellular Ca(2+) signaling that causes enhanced calcium-dependent Cl(-) conductance in cystic fibrosis.  

PubMed

In many cells, increase in intracellular calcium ([Ca(2+)](i)) activates a Ca(2+)-dependent chloride (Cl(-)) conductance (CaCC). CaCC is enhanced in cystic fibrosis (CF) epithelial cells lacking Cl(-) transport by the CF transmembrane conductance regulator (CFTR). Here, we show that in freshly isolated nasal epithelial cells of F508del-homozygous CF patients, expression of TMEM16A and bestrophin 1 was unchanged. However, calcium signaling was strongly enhanced after induction of expression of F508del-CFTR, which is unable to exit the endoplasmic reticulum (ER). Since receptor-mediated [Ca(2+)](i) increase is Cl(-) dependent, we suggested that F508del-CFTR may function as an ER chloride counter-ion channel for Ca(2+). This was confirmed by expression of the double mutant F508del/G551D-CFTR, which remained in the ER but had no effects on [Ca(2+)](i). Moreover, F508del-CFTR could serve as a scavenger for inositol-1,4,5-trisphosphate [IP3] receptor binding protein released with IP(3) (IRBIT). Our data may explain how ER-localized F508del-CFTR controls intracellular Ca(2+) signaling. PMID:21907281

Revertants, low temperature, and correctors reveal the mechanism of F508del-CFTR rescue by VX-809 and suggest multiple agents for full correction.  

PubMed

Cystic fibrosis is mostly caused by the F508del mutation, which impairs CFTR protein from exiting the endoplasmic reticulum due to misfolding. VX-809 is a small molecule that rescues F508del-CFTR localization, which recently went into clinical trial but with unknown mechanism of action (MoA). Herein, we assessed if VX-809 is additive or synergistic with genetic revertants of F508del-CFTR, other correctors, and low temperature to determine its MoA. We explored and integrated those various agents in combined treatments, showing how they add to each other to identify their complementary MoA upon correction of F508del-CFTR. Our experimental and modeling data, while compatible with putative binding of VX-809 to NBD1:ICL4 interface, also indicate scope for further synergistic F508del-CFTR correction by other compounds at distinct conformational sites/cellular checkpoints, thus suggesting requirement of combined therapies to fully rescue F508del-CFTR.

L10P and P158DEL DJ-1 Mutations Cause Protein Instability, Aggregation, and Dimerization Impairments  

PubMed Central

A variety of mutations in the gene encoding DJ-1 protein are causal of autosomal recessive early-onset parkinsonism. Recently, a novel pathogenic homozygous DJ-1 missense mutation resulting in the L10P amino acid substitution was reported. In a separate study, a novel homozygous mutation resulting in the deletion of DJ-1 residue P158 was also reported to be causative of disease. The specific effects of the novel L10P and P158DEL mutations on protein function have not been studied. Herein, L10P and P158DEL DJ-1 proteins were assessed for protein stability, dimerization, solubility, subcellular localization, and protective function in comparison to WT and the L166P DJ-1 pathogenic variant. It was discovered that in comparison to WT protein, L10P, L166P, and P158DEL DJ-1 variants exhibited dramatically reduced protein stabilities. Degradation of each of the respective pathogenic mutants appeared to be mediated in-part by the proteasome. Interestingly, unlike L166P DJ-1, the L10P and P158DEL DJ-1 variants retained the ability to dimerize with WT DJ-1 protein; however, neither of these mutants was able to form homodimers. Additionally, the L10P, L166P, and P158DEL DJ-1 variants exhibited altered profiles on size-exclusion chromatography and demonstrated reduced solubilities in comparison to WT protein, and the latter aberration could be exacerbated in the presence of MG-132. Further, cells stably expressing L10P DJ-1 were more vulnerable to treatments with proteasome inhibitors, suggesting that L10P DJ-1 may be toxic to cells under conditions of proteasome stress. Taken together, these findings suggest that diverse aberrant mechanisms, including alterations in protein stability and protein folding, are associated with the pathogenicity of the L10P and P158DEL DJ-1 variants.

An inverse problem for localization operators  

NASA Astrophysics Data System (ADS)

A classical result of time-frequency analysis, obtained by Daubechies in 1988, states that the eigenfunctions of a time-frequency localization operator with circular localization domain and Gaussian analysis window are the Hermite functions. In this contribution, a converse of Daubechies’ theorem is proved. More precisely, it is shown that, for simply connected localization domains, if one of the eigenfunctions of a time-frequency localization operator with Gaussian window is a Hermite function, then its localization domain is a disc. The general problem of obtaining, from some knowledge of its eigenfunctions, information about the symbol of a time-frequency localization operator is denoted as the inverse problem, and the problem studied by Daubechies as the direct problem of time-frequency analysis. Here, we also solve the corresponding problem for wavelet localization, providing the inverse problem analogue of the direct problem studied by Daubechies and Paul.

Local Conservation Laws and the Structure of the Many-Body Localized States  

NASA Astrophysics Data System (ADS)

We construct a complete set of local integrals of motion that characterize the many-body localized (MBL) phase. Our approach relies on the assumption that local perturbations act locally on the eigenstates in the MBL phase, which is supported by numerical simulations of the random-field XXZ spin chain. We describe the structure of the eigenstates in the MBL phase and discuss the implications of local conservation laws for its nonequilibrium quantum dynamics. We argue that the many-body localization can be used to protect coherence in the system by suppressing relaxation between eigenstates with different local integrals of motion.

Matryoshka locally resonant sonic crystal.  

PubMed

The results of numerical modeling of sonic crystals with resonant array elements are reported. The investigated resonant elements include plain slotted cylinders as well as their various combinations, in particular, Russian doll or Matryoshka configurations. The acoustic band structure and transmission characteristics of such systems have been computed with the use of finite element methods. The general concept of a locally resonant sonic crystal is proposed that utilizes acoustic resonances to form additional band gaps that are decoupled from Bragg gaps. An existence of a separate attenuation mechanism associated with the resonant elements that increases performance in the lower frequency regime has been identified. The results show a formation of broad band gaps positioned significantly below the first Bragg frequency. For low frequency broadband attenuation, a most optimal configuration is the Matryoshka sonic crystal, where each scattering unit is composed of multiple concentric slotted cylinders. This system forms numerous gaps in the lower frequency regime, below Bragg bands, while maintaining a reduced crystal size viable for noise barrier technology. The finding opens alternative perspectives for the construction of sound barriers in the low frequency range usually inaccessible by traditional means including conventional sonic crystals.

Segmentation in local hospital markets.  

PubMed

This study examines evidence of market segmentation on the basis of patients' insurance status, demographic characteristics, and medical condition in selected local markets in California in the years 1983 and 1989. Substantial differences exist in the probability patients may be admitted to particular hospitals based on insurance coverage, particularly Medicaid, and race. Segmentation based on insurance and race is related to hospital characteristics, but not the characteristics of the hospital's community. Medicaid patients are more likely to go to hospitals with lower costs and fewer service offerings. Privately insured patients go to hospitals offering more services, although cost concerns are increasing. Hispanic patients also go to low-cost hospitals, ceteris paribus. Results indicate little evidence of segmentation based on medical condition in either 1983 or 1989, suggesting that "centers of excellence" have yet to play an important role in patient choice of hospital. The authors found that distance matters, and that patients prefer nearby hospitals, moreso for some medical conditions than others, in ways consistent with economic theories of consumer choice.

Cannabinoid receptor localization in brain.  

PubMed Central

[3H]CP 55,940, a radiolabeled synthetic cannabinoid, which is 10-100 times more potent in vivo than delta 9-tetrahydrocannabinol, was used to characterize and localize a specific cannabinoid receptor in brain sections. The potencies of a series of natural and synthetic cannabinoids as competitors of [3H]CP 55,940 binding correlated closely with their relative potencies in several biological assays, suggesting that the receptor characterized in our in vitro assay is the same receptor that mediates behavioral and pharmacological effects of cannabinoids, including human subjective experience. Autoradiography of cannabinoid receptors in brain sections from several mammalian species, including human, reveals a unique and conserved distribution; binding is most dense in outflow nuclei of the basal ganglia--the substantia nigra pars reticulata and globus pallidus--and in the hippocampus and cerebellum. Generally high densities in forebrain and cerebellum implicate roles for cannabinoids in cognition and movement. Sparse densities in lower brainstem areas controlling cardiovascular and respiratory functions may explain why high doses of delta 9-tetrahydrocannabinol are not lethal. Images

Carrier localization in gallium nitride  

SciTech Connect

In wide bandgap GaN, a large number of interesting and important scientific questions remain to be answered. For example, the large free electron concentration reaching 10{sup 19} to 10{sup 20} cm{sup - 3} in nominally undoped material are ascribed to intrinsic defects because no chemical impurity has been found at such high concentrations. According to theoretical models, a nitrogen vacancy acts as a donor but its formation energy is very large in n-type materials, making this suggestion controversial. We have investigated the nature of this yet unidentified donor at large hydrostatic pressure. Results from infrared reflection and Raman scattering indicate strong evidence for localization of free carriers by large pressures. The carrier density is drastically decreased by two orders of magnitude between 20 and 30 GPa. Several techniques provide independent evidence for results in earlier reports and present the first quantitative analysis. A possible interpretation of this effect in terms of the resonant donor level is presented.

Local hardness equalization: Exploiting the ambiguity  

NASA Astrophysics Data System (ADS)

In the density-functional theory of chemical reactivity, the local hardness is known to be an ambiguous concept. The mathematical structure associated with this problematic situation is elaborated and three common definitions for the local hardness are critically examined: the frontier local hardness [S. K. Ghosh, Chem. Phys. Lett. 172, 77 (1990)], the total local hardness [S. K. Ghosh and M. Berkowitz, J. Chem. Phys. 83, 2976 (1985)], and the unconstrained local hardness [P. W. Ayers and R. G. Parr, J. Am. Chem. Soc. 122, 2010 (2000)]. The frontier local hardness has particularly nice properties: (a) it has smaller norm than most, if not all, other choices of the local hardness and (b) it is ``unbiased'' in an information-theoretic sense. For the ground electronic state of a molecular system, the frontier local hardness is equal to the global hardness. For an electronic system in its ground state, both the chemical potential and the frontier local hardness are equalized. The frontier local hardness equalization principle provides a computational approach for designing reagents with desirable chemical reactivity profiles.

Covariation analysis of local amino acid sequences in recurrent protein local structures.  

PubMed

Local structural information is supposed to be frequently encoded in local amino acid sequences. Previous research only indicated that some local structure positions have specific residue preferences in some particular local structures. However, correlated pairwise replacements for interacting residues in recurrent local structural motifs from unrelated proteins have not been studied systematically. We introduced a new method fusing statistical covariation analysis and local structure-based alignment. Systematic analysis of structure-based multiple alignments of recurrent local structures from unrelated proteins in representative subset of Protein Databank indicates that covarying residue pairs with statistical significance exist in local structural motifs, in particular beta-turns and helix caps. These residue pairs are mostly linked through polar functional groups with direct or indirect hydrogen bonding. Hydrophobic interaction is also a major factor in constraining pairwise amino acid residue replacement in recurrent local structures. We also found correlated residue pairs that are not clearly linked with through-space interactions. The physical constrains underlying these covariations are less clear. Overall, covarying residue pairs with statistical significance exist in local structures from unrelated proteins. The existence of sequence covariations in local structural motifs from unrelated proteins indicates that many relics of local relations are still retained in the tertiary structures after protein folding. It supports the notion that some local structural information is encoded in local sequences and the local structural codes could play important roles in determining native state protein folding topology.

We report the prediction of fully localized two-dimensional embedded solitons. These solitons are obtained in a quasi-one-dimensional waveguide array which is periodic along one spatial direction and localized along the orthogonal direction. Under appropriate nonlinearity, these solitons are found to exist inside the Bloch bands (continuous spectrum) of the waveguide and thus are embedded solitons. These embedded solitons are fully localized along both spatial directions. In addition, they are fully stable under perturbations.

Local government and demand-side bidding  

SciTech Connect

As part of Lawrence Berkeley Laboratory's (LBL) technical assistance to the Sustainable City Project, the issue of DSM bidding was examined as a possible option for local government. The recent interest and activity in DSM bidding around the country presents an opportunity for local government. Potential benefits for local government include increased installation of energy efficiency measures in municipal facilities and in the community, economic development, an additional source of revenue to help pay for municipal programs (including additional conservation efforts), and an enhanced local image. Local government will most likely participate in DSM bidding as a customer or as a client of an energy service company (ESCO). The exact role will depend on local government's response to key issues associated with DSM bidding, such as performance guarantees, quality assurance procedures (measuring savings and providing financial security), and the administrative burden. In addition, local government will have to weigh the advantages and disadvantages of working with an ESCO. While local government has not yet participated in DSM bidding, local government is in a unique position to take advantage of energy efficiency opportunities as owner-operators of municipal facilities which consume significant amounts of energy, planners and regulators of new development, and general providers of services and assistance to their communities. Furthermore, local governments have lower risks (in terms of program success) than small businesses, and local governments' credibility and experience in dealing with customers may reduce high transaction costs associated with DSM bidding. Despite these advantages, local governments should take a cautious approach in participating in DSM bidding processes, and should carefully examine other strategies for promoting energy efficiency (including participation in conventional utility programs) prior to participating in DSM bidding.

An evening at "La Clinica del Pueblo".

This article describes a typical evening at the Clinica del Pueblo in the Hispanic neighborhood of Adams-Morgan in Washington, D.c. The Clinical del Pueblo began operating in 1983 in response to the urgen medical needs of Central American refugees arriving in the Washington D.c. area. The refugees bring with them severe trauma, fear, and health problems caused by the civil was and exacerbated by inadequate or non-existant health services. Approximately 80,000 Salvadoran refugees live in the area. They do not receive adequate health care for 3 reasons. 1) Because the US goverment is unwilling to recognize them as true refugees, they live with the constant threat of deportatin back to the violence from which they have fled. 2) Refugees lack the ability to pay for private care. 3) Langauage and culture create frightening barriers to health care for the refugees. For those who do seek care, these barriers can lead to the inadequate or incomplete diagnoses and poor compliance and follow-up. Plenty International and the Central American Refugee Center responded to these problems by organizing a free clinic to provide not only medical care but also a training course for volunteers. The director of the clinic organizes the course, the classes are taught by a variety of people including the clinic's volunteer physicians, nurses, and public health educators as well as graduates of previus training courses and people from the wider community. The services of the clinic reach only a small portion of the population in need. However, the fact that free medical services are now available to some Central American refugees make the Clinica del Pueblo an important program. PMID:12281149

Lipid emulsion for local anesthetic systemic toxicity.  

PubMed

The accidental overdose of local anesthetics may prove fatal. The commonly used amide local anesthetics have varying adverse effects on the myocardium, and beyond a certain dose all are capable of causing death. Local anesthetics are the most frequently used drugs amongst anesthetists and although uncommon, local anaesthetic systemic toxicity accounts for a high proportion of mortality, with local anaesthetic-induced cardiac arrest particularly resistant to standard resuscitation methods. Over the last decade, there has been convincing evidence of intravenous lipid emulsions as a rescue in local anesthetic-cardiotoxicity, and anesthetic organisations, over the globe have developed guidelines on the use of this drug. Despite this, awareness amongst practitioners appears to be lacking. All who use local anesthetics in their practice should have an appreciation of patients at high risk of toxicity, early symptoms and signs of toxicity, preventative measures when using local anesthetics, and the initial management of systemic toxicity with intravenous lipid emulsion. In this paper we intend to discuss the pharmacology and pathophysiology of local anesthetics and toxicity, and the rationale for lipid emulsion therapy. PMID:21969824

When local isn't best  

PubMed Central

This paper attempts to explain circumstances under which local may be or may not be best. Natural selection may lead to local adaptation (LA), or it may be constrained by gene flow, founder effects, small population size, genetic drift, and archetype. ‘Specialist’ species display greater LA than ‘generalist’ species. Local genotypes are to a certain extent transient, being a consequence of past historical genetic patterns. Two recent meta-analyses found that while local performance exceeded the performance of a randomly chosen nonlocal population in 71% of comparisons, general adaptation across environments was as frequent as LA. Genotypes for restoration are most likely to be effective if they are adapted to current site conditions. As environmental change accelerates, both globally and locally, exceptions to ‘local is best’ may increase. For these reasons, ‘local is best’ may be better thought of as a testable hypothesis rather than as a general assumption. While either local or nonlocal plant material may be most effective for restoration practice depending on individual circumstances, local material will continue to be the first choice for restoration practitioners whenever this option is feasible and effective.

Angular momentum in the Local Group  

SciTech Connect

We briefly review models for the Local Group and the acquisition of its angular momentum. We describe early attempts to understand the origin of the spin of the galaxies discussing the hypothesis that the Local Group has little angular momentum. Finally we show that using Peebles` least action principle there should be a rather large amount of orbital angular momentum compared to the magnitude of the spin of its galaxies. Therefore the Local Group cannot be thought as tidally isolated. Using Peebles` trajectories we give a possible set of trajectories for Local Group galaxies which would predict their spin.

Localization and holography in gauge theories  

NASA Astrophysics Data System (ADS)

We compare exact results from Pestun's localization [1] of SU( N) gauge theory on S 4 with available holographic models. While localization can explain the Coulomb branch vacuum of the holographic Pilch-Warner flow [2], it disagrees with the holographic Gauntlett et al. [3] vacuum of super Yang-Mills theory. We further compute the free energy of the Pilch-Warner flow on S 4 and show that it disagrees with the localization result both for a finite S 4 radius, and in the S 4 decompactification limit. Thus, neither model represents holographic dual of supersymmetric S 4 localization of [1].

Functional Localization of Genetic Network Programming  

NASA Astrophysics Data System (ADS)

According to the knowledge of brain science, it is suggested that there exists cerebral functional localization, which means that a specific part of the cerebrum is activated depending on various kinds of information human receives. The aim of this paper is to build an artificial model to realize functional localization based on Genetic Network Programming (GNP), a new evolutionary computation method recently developed. GNP has a directed graph structure suitable for realizing functional localization. We studied the basic characteristics of the proposed system by making GNP work in a functionally localized way.

THE LOCAL LIMIT OF GLOBAL GYROKINETIC SIMULATIONS  

SciTech Connect

OAK-B135 Global gyrokinetic simulations of turbulence include physical effects that are not retained in local flux-tube simulations. nevertheless, in the limit of sufficiently small {rho}* (gyroradius compared to system size) it is expected that a local simulation should agree with a global one (at the local simulation radius) since all effects that are dropped in the local simulations are expected to vanish as {rho}* {yields} 0. In this note, global simulations of a well-established test case are indeed shown to recover the flux-tube limit at each radius.

Do local and global perceptual biases tell us anything about local and global selective attention?  

PubMed

Local, as opposed to global, perceptual bias has been linked to a lesser ability to attend globally. We examined this proposed link in Himba observers, members of a remote Namibian population who have demonstrated a strong local bias compared with British observers. If local perceptual bias is related to a lesser ability to attend globally, Himba observers, relative to British observers, should be less distracted by global information when performing a local-selection task but more distracted by local information when performing a global-selection task. However, Himba observers performed better than British observers did on both a local-selection task and a global-selection task (both of which used local/global hierarchical figures as stimuli), which suggests that they possessed greater control over attentional selection in response to task demands. We conclude that local and global perceptual biases must be distinguished from local and global selective attention. PMID:23300230

On speciation of VOC localization  

NASA Astrophysics Data System (ADS)

Most of the gas-phase chemical mechanisms successfully used in gas-phase atmospheric chemical processes, such as CBM-Z, RADM2 or SAPRC-07, treat hundreds of VOC as lumped organic species by their chemical characteristics. Most of the model results are compared with total VOC observations, and it is not appropriate to compare lumped VOC simulations to observations even if there are separate VOC observations like Photochemical Assessment Monitoring Stations (PAMS). While the PAMS Air Quality Model (PAMS-AQM) is developed, separate organic species observed by PAMS without a doubt can be directly compared with model simulations. From the past case study (Chen et al., 2010), it shows a major and very significant finding in that detailed emissions of VOC in the existing emissions database are often in error in Taiwan or other countries due to the fact that the annual VOC emissions are classified into hundreds of species-specific emissions by using the speciation factors following the protocol of the U.S. EPA (AP-42). Based on all PAMS observations from 2006-2007, four base cases with well comparable meteorological simulations were selected for the unified correction for all sources in Taiwan. After the PAMS species emissions are modified, the diurnal patterns and simulation-observation correlation for most of the PAMS species are improved, and the concentration levels are more comparable with those of observations. More expanded case studies also revealed necessary corrections for the PAMS species emissions. Sensitivity analyses for lumped organic species with modified PAMS species emissions are also conducted. After modified PAMS emissions are added into lumped VOC emissions, there is an increase of only 10% of totally VOC emissions. While the sources of the lumped VOC emissions are changed, ozone formation shows no significant change with modified lumped VOC emissions. This helps to support the argument that for ozone simulation, the lumped VOC processes balance out any shortcomings in VOC details and the simulation of oxidant levels remain unchanged. But for the detail emissions of VOC, one can find out the error with local VOC speciation and make corrections.

Interstellar Gas in the Local Chimneys  

NASA Astrophysics Data System (ADS)

We present ultraviolet absorption observations of four nearby (d < 250 pc) DA white dwarfs using spectral data (R˜15 km s-1) obtained with the NASA HST Cosmic Origins Spectrograph (1150-1700 Å) and the Far Ultraviolet Spectroscopic Explorer (912-1170 Å). Two of these targets (WD2321-549 and WD2124-224) sample gas along the Southern Local Chimney sight line, while WD1040+492 samples gas within the Northern Local Chimney and the sight line toward WD2257-073 samples gas located entirely within the central confines of the Local Interstellar Cavity. We have fit the numerous high and low ion interstellar absorption-line profiles with theoretical models in order to determine the velocity and ion column densities of the sight-line gas clouds. Using these data we have derived element abundances relative to that of (assumed undepleted) sulfur for each of the four sight lines. We find that the 89 pc sight line toward WD2257-73 reveals a pattern of element depletion associated with interstellar gas located within the inner Local Cavity that is greater than those derived for the other three sight lines that sample gas within the two Local Chimney features. The sight lines toward WD2124-224 and WD2321-549, which sample gas along the Southern Local Chimney, show patterns of element depletion that are greater than that derived for the Northern Local Chimney sight line toward WD1040+492. Although our sight line sample is small, these data seem to indicate that the interstellar gas located along both local chimneys may be chemically different from gas within the central regions of the Local Cavity. This may indicate that Local Chimney gas has a different physical history and origin from the interstellar gas located within the inner Local Cavity.

Assessment of local deformation using EBSD: Quantification of local damage at grain boundaries  

SciTech Connect

Electron backscatter diffraction (EBSD) in conjunction with scanning electron microscopy was used to assess localization of the local misorientation to grain boundary. In order to quantify the degree of localization, a parameter, which was referred to as the grain boundary local misorientation, was proposed. Through crystal orientation measurements using deformed Type 316 stainless steel, it was shown that the grain boundary local misorientation increased with the applied plastic strain. Particularly, at several grain boundaries, the grain boundary local misorientation was more than 3 times the local misorientation averaged for the whole area. Surface observations revealed that the large local misorientation near the grain boundaries was attributed to the impeded slip steps rather than the number of slip steps observed on the surface. The magnitude of the grain boundary local misorientation had a week correlation with grain boundary length or grain boundary misorientation, and no correlation was found for twin boundaries. Finally, it was shown that the maximum grain boundary local misorientation could be estimated statistically, and the estimated maximum value for the specimen surface with an area of 80 mm{sup 2} was 10.6 times the averaged value. - Highlights: Black-Right-Pointing-Pointer The grain boundary local misorientation was proposed. Black-Right-Pointing-Pointer The maximum grain boundary local misorientation could be estimated statistically. Black-Right-Pointing-Pointer The large local misorientation was attributed to the impeded slip steps.

These bounds depend on simple parameters like the number of measurement settings or the dimensionality of the entangled quantum state. We derive them by constructing explicit local hidden variable models which reproduce the quantum correlations for sufficiently small detectors efficiency.

Many problems in the FDTD require a relatively higher mesh resolution in only small sub-volumes of the total mesh space. By locally applying finer grids (local grids) to these volumes, the necessary resolution for these volumes can be obtained. The computational time and memory requirements may be far less than for an FDTD space with the smaller mesh resolution throughout.

Locally accessible information and distillation of entanglement  

SciTech Connect

A different type of complementarity relation is found between locally accessible information and final average entanglement for a given ensemble. It is also shown that in some well-known distillation protocols, this complementary relation is optimally satisfied. We discuss the interesting trade-off between locally accessible information and distillable entanglement for some states.

Universal mechanism for Anderson and weak localization  

PubMed Central

Localization of stationary waves occurs in a large variety of vibrating systems, whether mechanical, acoustical, optical, or quantum. It is induced by the presence of an inhomogeneous medium, a complex geometry, or a quenched disorder. One of its most striking and famous manifestations is Anderson localization, responsible for instance for the metal-insulator transition in disordered alloys. Yet, despite an enormous body of related literature, a clear and unified picture of localization is still to be found, as well as the exact relationship between its many manifestations. In this paper, we demonstrate that both Anderson and weak localizations originate from the same universal mechanism, acting on any type of vibration, in any dimension, and for any domain shape. This mechanism partitions the system into weakly coupled subregions. The boundaries of these subregions correspond to the valleys of a hidden landscape that emerges from the interplay between the wave operator and the system geometry. The height of the landscape along its valleys determines the strength of the coupling between the subregions. The landscape and its impact on localization can be determined rigorously by solving one special boundary problem. This theory allows one to predict the localization properties, the confining regions, and to estimate the energy of the vibrational eigenmodes through the properties of one geometrical object. In particular, Anderson localization can be understood as a special case of weak localization in a very rough landscape.
