Sampling Site Matters When Counting Lymphocyte Subpopulations  

PubMed Central

Clinical and scientific work routinely relies on antecubital venipunctures for hematological, immunological or other analyses on blood. This study tested the hypothesis that antecubital veins can be considered to be a good proxy for other sampling sites. Using a hematocytometer and a flow cytometer, we analyzed the cell counts from samples coming from the radial artery, the dorsal hand veins and the antecubital veins from 18 volunteers. Most surprisingly, we identified the greatest difference not to exist between arterial and venous circulation, but between the distal (radial artery & dorsal hand veins) and proximal (antecubital veins) sampling sites. Naïve T cells had a higher cell count distally compared to proximally and the reverse was true for effector memory T cells. Despite these differences there were high correlations between the different sampling sites, which partially supports our initial hypothesis. Our findings are crucial for the future design and interpretation of immunological research, and for clinical practice. Furthermore, our results suggest a role for interval lymph nodes in the trafficking of lymphocytes. PMID:22848485

Absolute Lymphocyte Count Is Not a Suitable Alternative to CD4 Count for Determining Initiation of Antiretroviral Therapy in Fiji  

PubMed Central

Introduction. An absolute lymphocyte count is commonly used as an alternative to a CD4 count to determine initiation of antiretroviral therapy for HIV-infected individuals in Fiji when a CD4 count is unavailable. Methods. We conducted a retrospective analysis of laboratory results of HIV-infected individuals registered at all HIV clinics in Fiji. Results. Paired absolute lymphocyte and CD4 counts were available for 101 HIV-infected individuals, and 96% had a CD4 count of ?500?cells/mm3. Correlation between the counts in individuals was poor (Spearman rank correlation r = 0.5). No absolute lymphocyte count could be determined in this population as a suitable surrogate for a CD4 count of either 350?cells/mm3?or 500?cells/mm3. The currently used absolute lymphocyte count of ?2300?cells/?L had a positive predictive value of 87% but a negative predictive value of only 17% for a CD4 of ?350 cells/mm3 and if used as a surrogate for a CD4 of ?500?cells/mm3 it would result in all HIV-infected individuals receiving ART including those not yet eligible. Weight, CD4 count, and absolute lymphocyte count increased significantly at 3 months following ART initiation. Conclusions. Our findings do not support the use of absolute lymphocyte count to determine antiretroviral therapy initiation in Fiji.

Effect of 6-day intense Kendo training on lymphocyte counts and its expression of CD95.  

PubMed

This study examines the effects of 6-day intensive training on lymphocyte counts and their expression of CD95. Eight healthy Kendo athletes underwent 6-day Kendo training of about 310 min each day. Blood samples were collected at 2 weeks before (PRE), the first day (Day 1), third day (Day 3), fifth day (Day 5), and 1 week after the training period (POST) to determine lymphocyte counts and CD95 expression on CD95 lymphocytes (CD4(+), CD8(+)) using flow cytometry. The total lymphocyte counts were significantly lower at Day 3 than at PRE. The CD8(+) cell counts were significantly lower at Day 3 than at PRE. The percentage of CD95(+) lymphocytes was significantly higher at Day 1 and Day 3 than at PRE. The percentage of CD8(+)CD95(+) cells did not change significantly. The total lymphocyte counts decreased and a concomitant increase of CD95(+) lymphocyte was observed, whereas the decrease in CD8(+) cell counts was not associated with the increase in CD8(+)CD95(+) cells. Therefore, short-term high-intensity exercise induced a decrease in the T lymphocyte counts without increasing in CD95(+) expression. PMID:19568765

Prognostic Value of Baseline Lymphocyte Count in Cervical Carcinoma Treated With Concurrent Chemoradiation  

SciTech Connect

Purpose: This study examined factors predicting tumor response and progression-free survival in patients with locally advanced cervical carcinoma treated with concurrent chemoradiation (CCRT). Methods and Materials: Medical records of 143 patients with locally advanced cervical carcinoma (International Federation of Gynecology and Obstetrics Stage IB2 to IVA) treated with CCRT were reviewed. Univariate and multivariate analyses were used to retrospectively evaluate prognostic factors, including baseline lymphocyte count, that affect tumor response and progression-free survival. Results: Of the variables evaluated, greater baseline lymphocyte count was the factor most predictive of a complete clinical response, followed by smaller tumor size (p = 0.003 and p = 0.007, respectively). Multivariate analysis showed baseline lymphocyte count, which was treated as a continuous variable with every 1 x 10{sup 9} lymphocytes/L, to remain a prognostic factor with an odds ratio of 3.08 (95% confidence interval, 1.31-7.23). In addition, a statistically significant association (p = 0.023) was found between baseline lymphocyte count and progression-free survival, with a hazard ratio of 0.42 (95% confidence interval, 0.20-0.89) in the Cox proportional hazards model. Conclusions: Despite the small number of patients and possible biologic variation existing in lymphocyte subset number and activity, these findings highlight the strong prognostic value of baseline lymphocyte count in patients with locally advanced cervical carcinoma treated with CCRT. Therefore, a larger number of patients and analysis of lymphocyte subsets are needed.

Emerging technologies for point-of-care CD4 T-lymphocyte counting  

PubMed Central

A CD4 T-lymphocyte count determines eligibility for antiretroviral therapy (ART) with patients recently diagnosed with HIV and also monitors the efficacy of ART treatment thereafter. ART slows the progression of HIV to AIDS. In the developing world, CD4 tests are often performed in centralized laboratories, typically in urban areas. The expansion of ART programs into rural areas has created a need for rapid CD4 counting as logistical barriers can delay the timely dissemination of test results and affect patient care through delay in intervention or loss of follow-up care. CD4 measurement at the point-of-care (POC) in rural areas could help facilitating ART and monitoring of treatment. This review highlights recent technology developments with applications towards determining CD4 counts at the POC. PMID:21798607

Effects of the space flight environment on man's immune system. II - Lymphocyte counts and reactivity.  

NASA Technical Reports Server (NTRS)

The present studies were undertaken to assess the effects of the environment of space flights on the cellular division of the human immune system. Peripheral blood absolute lymphocyte counts were determined at various preflight and postflight intervals for the 21 crewmen of Apollo Missions 7-13. Mean lymphocyte numbers tended to exhibit a delayed significant but fluctuating increase shortly after recovery, although a variety of responses was seen in individual astronauts. The in vitro reactivity of lymphocytes, reflected by RNA and DNA synthesis rates by unstimulated and PHA-stimulated lymphocytes tissue-cultured preflight and postflight from the same participants, was found to remain within previously established normal ranges. These results indicate that functional integrity of cellular immune potential as reflected by in vitro techniques is maintained during this spaceflight experience.

Absolute Lymphocyte Count as a Predictor of Mortality in Emergency Department Patients with Paraquat Poisoning  

PubMed Central

Background Paraquat (PQ) is a potent, highly toxic and widely used herbicide. The major medical problems associated with PQ are accidental or suicidal ingestion. There are several prognostic markers of PQ poisoning, with the serum PQ concentration considered to be the best indicator of outcome. However, the measurement of such markers is limited in many hospitals. Objective The present study was conducted to investigate the association of absolute lymphocyte count (ALC) and the 30-day mortality rate in patients with PQ poisoning. Methods We performed a retrospective analysis of patients admitted to the emergency department after paraquat poisoning between January 2010 and April 2013. Independent risk factors including ALC for 30-day mortality were determined. The ALC was categorized in quartiles as ?1700, 1700 to 3200, 3200 to 5000, and >5000. Univariate and multivariate Cox proportional hazard analysis were performed to determine the independent risk factors for mortality. Results A total of 136 patients were included in the study, and the 30-day mortality was 73.5%. ALC was significantly higher in nonsurvivors than in survivors. The highest ALC quartile (ALC>5000; hazard ratio, 2.58; 95% CI, 1.08–6.21) was associated with increased mortality in multivariate analysis. In addition, old age, lower arterial PaCO2, increased peripheral neutrophil count, and high serum levels of creatinine were associated with mortality. Conclusion The absolute lymphocyte count is associated with the 30-day mortality rate in patients with paraquat poisoning. PMID:24205140

Counting Circles  

NSDL National Science Digital Library

Have students stand and form a circle facing in toward each other. Select a counting sequence to be practiced with no more than 8-10 numbers in the sequence. Have the students start counting around the circle one by one until the last number in the sequence is reached. When the last number is reached all students clap and that student is out and sits down on the floor in the middle of the circle. Start the counting sequence over again until another student reaches the number at the end of the sequence; everyone claps and that student sits in the center with the first student. Continue repeating the sequence until only one child is left standing and the rest are seated in the center of the circle. For example: for the counting sequence 1-10: the first student says "one," the next student says "two" and so on until the 10th students gets to "ten" at this point everyone claps and the tenth child sits in the center of the circle. The eleventh student starts over with "one" and so on.

Total lymphocyte count as a surrogate marker to predict CD4 count in human immunodeficiency virus-infected children: a retrospective evaluation.  

PubMed

A retrospective study was conducted, and 576 human immunodeficiency virus-infected children with total lymphocyte count (TLC) and CD4 count were recruited from China. Spearman rank order correlation and receiver-operating characteristic were used. An overall positive correlation was noted between TLC and CD4 count (prehighly active antiretroviral therapy [pre-HAART], r = 0.789, 6 months of HAART, r = 0.642, 12 months of HAART, r = 0.691, P = 0.001). TLC ? 2600 cells/mm(3) predicted a CD4 count of ? 350 cells/mm(3) with 82.9% sensitivity, 79.6% specificity pre-HAART. Meanwhile, the optimum prediction for CD4 count of ? 350 cells/mm(3) was a TLC of ? 2400 cells/mm at 6 months (73.6% sensitivity and 74.1% specificity) and 12 months (81.7% sensitivity and 76.5% specificity) of HAART. TLC can be used as a surrogate marker for predicting CD4 count of human immunodeficiency virus-infected children before and during HAART in resource-limited countries. PMID:22217967

Utility of total lymphocyte count as a surrogate for absolute CD4 count in the adult Indian HIV population: A prospective study  

PubMed Central

Background: Standard methods of CD4 counts and plasma viral load estimation require specialized equipment, highly trained personnel and are extremely expensive. This remains a major challenge for the initiation of anti-retroviral therapy for patients in resource-limited settings. Objective: To assess the clinical utility of the total lymphocyte count (TLC) to serve as a surrogate marker for predicting a CD4 counts <350 cell/mm3 in patients with HIV. Materials and Methods: A prospective study of 200 consecutive newly detected highly active anti-retroviral therapy (HAART) naïve HIV patients admitted over a one year period was conducted. Linear regression, Pearson correlation and receiver operating characteristic (ROC) curves were used to calculate the relationship between TLC and CD4 counts. Results: A significant correlation between TLC and CD4 count was observed (r = 0.682, P < 0.001). TLC cut off of 1200 cell/mm3 as a predictor of CD4 count <350 cell/mm3 had 73.1% sensitivity, 100% specificity, 100% positive predictive value (PPV) and 51.4% negative predictive value (NPV). Raising the cutoff to 1500 cells/mm3 improved the sensitivity to 82.1% with 88.2% specificity, 96.5% PPV, 44.4% NPV. The ROC curve demonstrated highest area under curve (AUC = 0.8) for TLC of 1500 cell/mm3. Conclusion: The study showed that TLC cutoff value of 1500 cells/mm3 was a cost effective surrogate marker for CD4 counts <350 cells/mm3 in resource-limited settings. PMID:24678463

Significance of Preoperative Total Lymphocyte Count as a Prognostic Criterion in Adult Cardiac Surgery  

PubMed Central

Background: Evaluation of operational risk is a consequential goal in perioperative management of patients in cardiac surgery. Preoperative total lymphocyte count (PTLC) is a prognostic criterion of adverse major cardiovascular outcomes. Objectives: The purpose of this study was to investigate the prognostic value of PTLC as an independent predictor of postoperative morbidity and mortality in cardiac surgery. Patients and Methods: Of 1604 patients scheduled for cardiac surgery between September, 2012 and March, 2013, a total of 1171 consecutive patients underwent elective primary valvular heart surgery and coronary artery bypass grafting. The patients were divided to three groups according to their PTLCs. The baseline characteristics and postoperative mortality and morbidity of the patients as well as the intensive care unit (ICU) stay according to the PTLCs were recorded and analyzed. The only inclusion criterion was a preoperative complete blood count. Exclusion criteria included: ages under 18 or over 80 years old, emergency surgery, adult patients with congenital heart disease and previous open heart surgery, and patients with any bacterial or viral infection during two weeks before the surgery. Protocol of anesthetic medications was used in all the patients similarly and according to standard. All the patients were admitted to the ICU after the surgery. Results: A PTLC < 1500 cells/µL was associated with significantly high mortality and morbidity (P = 0.0001). In-hospital mortality and major composite morbidity were 9.65% and 28.4%, respectively. Low PTLC was associated with more frequent need for inotropic and intra-aortic balloon pump (IABP) support (P < 0.001), dialysis-dependent acute renal failure (P = 0.0001), postoperative superficial wound infections (P = 0.0001) and prolong ICU stay (P = 0.0001). Conclusions: Our study results showed that low PTLC was an independent, valuable prognostic criterion, with high sensitivity and specificity for evaluation of postoperative morbidity and mortality in cardiac surgery.

Evaluation of the Alere Pima™ for CD4+ T lymphocytes counts in HIV-positive outpatients in Southern Brazil.  

PubMed

CD4?+?lymphocyte counts are routinely ordered during the early phases of antiretroviral therapy and for prophylaxis of opportunistic infections in HIV-positive patients. Flow cytometry is the standard methodology for CD4 counts in Brazilian reference laboratories. However, these laboratories are located in large cities, frequently distant from patients, thus limiting patient access and delaying results. We compared a point-of-care test with flow cytometry determination of CD4(+) T lymphocyte counts in HIV patients. We analysed 107 consecutive samples by both methods. Overall, the point-of-care test performed well, with excellent agreement between it and the standard method. Test results were concordant for patients with CD4(+) T lymphocyte values above and below 200 cells/mm?(3). The performance characteristics obtained were sensitivity 94% (95% CI 89.5-98.5%), specificity 93% (95% CI 88.2-97.8%), positive predictive value 86% (95% CI 79.4-92.6%), and negative predictive value 97% (95% CI 94-100%). The high sensitivity and specificity of the point-of-care test methodology suggest its utility as an alternative method for rapid measurement of CD4(+) T lymphocytes in patients with limited access to reference laboratories, enabling prompt therapeutic intervention for patients at risk of progression to AIDS.

Evaluating Total Lymphocyte Count as a Surrogate Marker for CD4 Cell Count in the Management of HIV-Infected Patients in Resource-Limited Settings: A Study from China  

PubMed Central

Objective To evaluate the correlation of total lymphocyte count (TLC) and CD4 cell count and the suitability of TLC as a surrogate marker for CD4 cell count of HIV-infected patients in China. Methods Usefulness of TLC as a surrogate marker for a CD4 cell count <350 cells/mm3 for HIV-positive patients in China was evaluated by 977 pairs of TLC and CD4 cell count from 977 outpatients. The result was then validated by a literature review which was conducted on 9 relevant articles. Further investigation using the 977 pairs of TLC and CD4 cell count data was done to determine a TLC threshold for predicting a CD4 cell count <500 cells/mm3. Correlation and receiver operating characteristic (ROC) analysis were performed for both CD4 cell counts, and the sensitivity and specificity were computed. Results Good correlation was noted between TLC and CD4 count (r?=?0.60, 95% CI, 0.56–0.64). TLC obtained a relatively high diagnostic performance (area under ROC curve, 0.80) for predicting a CD4 cell count <350 cells/mm3, with a sensitivity of 0.65 (95% CI, 0.61–0.68) and a specificity of 0.80 (95% CI, 0.75–0.85) at the TLC threshold of 1570 cells/mm3. The literature review suggested that for a CD4 cell count <350 cells/mm3, the optimal TLC threshold was 1500 cells/mm3, which was similar to the figure presented in this observational study. As for predicting a CD4 cell count <500 cells/mm3, TLC obtained a high diagnostic performance (area under ROC curve, 0.82) as well with a sensitivity of 0.70 (95% CI, 0.67–0.73) and a specificity of 0.80 (95% CI, 0.73–0.87). Conclusions When considering the antiretroviral therapy for HIV-infected Chinese individuals, total lymphocyte count can be considered as an inexpensive and easily available surrogate marker for predicting two clinically important thresholds of CD4 count of 350 cells/mm3 and 500 cells/mm3.

Cutaneous presentation of chronic lymphocytic leukemia as unique extramedullar involvement in a patient with normal peripheral blood lymphocyte count (monoclonal B-cell lymphocytosis).  

PubMed

Skin infiltration by chronic lymphocytic leukemia (CLL) is very rare and almost all reported cases occur in advanced stage. We report a patient with no relevant past medical history who presented with cutaneous erythematous plaques. A punch biopsy showed typical CLL morphologic and immunophenotypic features. Subsequent studies revealed a normal lymphocyte count in peripheral blood, and there was no evidence of lymphadenopathy or organomegaly. Flow cytometry demonstrated a clonal B-cell population both in the bone marrow and peripheral blood (1.60 × 10(9)/l) with a CLL phenotype, but it did not fulfill required criteria for CLL diagnosis. Without cutaneous involvement, this case should be classified as monoclonal B-cell lymphocytosis. PMID:23639136

Are albumin and total lymphocyte count significant and reliable predictors of mortality in fractured neck of femur patients?  

PubMed

Hip fractures are a significant cause of mortality and morbidity in the elderly. It is important to identify factors that predict an increased mortality following hip fracture. The aim of this study was to identify significant predictors of mortality at 6 and 12 months following hip fractures. Three hundred patients above the age of 65 were identified who were admitted in to the hospital with fracture neck of femur. Two hundred and seventy-four patients were operated and were included into the study. Variables collected were age, gender, significant comorbidities, admission albumin level and admission total lymphocyte count (TLC). Admission time and subsequent time to surgery were also analysed. Our study showed that albumin and TLC were found to be the only clearly significant mortality predictors at 12 months and a delay of up to 4 days to surgery does not significantly increase the mortality at 12 months.

Prognostic Impact of Absolute Lymphocyte Counts at the End of Remission Induction in Childhood Acute Lymphoblastic Leukemia  

PubMed Central

Background Absolute lymphocyte counts (ALC) during treatment have been associated with outcome in children and adults with hematologic malignancies. However, the impact of ALC relative to that of other prognostic factors on the outcome of children with acute lymphoblastic leukemia (ALL) treated in recent trials is unknown. Methods Outcomes of 399 patients ? 18 years of age with newly diagnosed ALL who were enrolled in the Total Therapy XV study at St. Jude Children’s Research Hospital were analyzed according to ALC at the end of remission induction therapy. Results ALC ? 500 cell/?L was significantly more prevalent among patients with B-lineage ALL, favorable presenting features and in those who achieved minimal residual disease (MRD) negativity on day 43 of treatment. Both overall survival (OS) and event-free survival (EFS) were superior among patients with higher ALC, but only the association with OS was statistically significant in a univariate analysis. In multivariable analyses, ALC was not a significant predictor of outcome after controlling for age, leukocyte count, lineage, risk group, and MRD at the end of induction (p > 0.1 for all comparisons). However, among MRD-negative patients, those with low ALC had a 5-year OS of 84.2% ± 8.9% versus 97.3 ± 1.0 for patients with higher ALC (P = .036). Conclusion ALC at the end of induction is related to favorable presenting features and good initial treatment response but does not independently predict outcome in the context of contemporary, MRD-guided, therapy.

Counting glycans revisited.  

PubMed

We present an algorithm for counting glycan topologies of order [Formula: see text] that improves on previously described algorithms by a factor [Formula: see text] in both time and space. More generally, we provide such an algorithm for counting rooted or unrooted [Formula: see text]-ary trees with labels or masses assigned to the vertices, and we give a "recipe" to estimate the asymptotic growth of the resulting sequences. We provide constants for the asymptotic growth of [Formula: see text]-ary trees and labeled quaternary trees (glycan topologies). Finally, we show how a classical result from enumeration theory can be used to count glycan structures where edges are labeled by bond types. Our method also improves time bounds for counting alkanes. PMID:23974240

Counting and language.  

PubMed

(Full text is available at http://www.manu.edu.mk/prilozi). Number words could be considered as a part of general verbal lexicon, although clinical and scientific data suggest that there are specific brain areas that are involved in specific aspects of number and language processing. In this fMRI study we examine the brain response to two number words generation tasks that should be closely related to the process of language generation: counting forward and counting backward. Our results imply that both investigated tasks strongly rely on brain structures usually related to language generation processes with a distinct activation of the prefronatal area for both counting tasks. Furthermore, we found differences in brain response among the investigated tasks regarding activation in the posterior part of the superior temporal gyrus and parietal cortex for the task of counting backward. Those findings suggest that the tasks of counting rely on established language-related brain areas with specific differences depending on cognitive content of the specified task. Key words: fMRI, counting, language generation. PMID:23037186

Whose interests count?  

PubMed

Whose interests should count and how should various interests be balanced at the pediatric patient's bedside? The interests of the child patient clearly count. Recently, however, many authors have argued that the family's interests also count. But how should we think about the interests of others? What does it mean to talk about "the family" in this context? Does it really just mean the interests of each individual family member? Or is the family itself a moral entity that has interests of its own independent of the interests of each of its members? Are such interests important only as they affect the patient's interest or also for their own sake? In this special supplement to Pediatrics, a group of pediatricians, philosophers, and lawyers grapple with these questions. They examine these issues from different angles and reach different conclusions. Jointly, they demonstrate the ethical importance and, above all, the ethical complexity of the family's role at the bedside. PMID:25274878

Prime Counting Function Model  

NSDL National Science Digital Library

The Prime Counting Function model uses the trial division algorithm to compute the number of primes less than or equal to the number n. Although the trial division algorithm is inefficient, we use it to perform a lengthy calculation while a standard EJS simulation thread accumulates and plots data from the parallel computation. Users can vary the number of independent threads and observe the computational time. The Prime Counting Function 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 model's jar file will run the simulation if Java is installed.

Prognostic value of preoperative absolute lymphocyte count in recurrent hepatocellular carcinoma following thermal ablation: a retrospective analysis  

PubMed Central

Purpose To investigate the prognostic value of preoperative absolute lymphocyte count (ALC) in recurrent hepatocellular carcinoma (RHCC) following thermal ablation. Materials and methods We retrospectively analyzed the relationship between preoperative ALC and the clinicopathologic factors and long-term prognosis in 423 RHCC patients who underwent curative thermal ablation. Correlation analysis, receiver operating characteristic (ROC) calculation, Kaplan–Meier curves, and multivariate regression were used for statistical analysis. Results The median time to recurrence was 12 months for RHCC patients after thermal ablation. On multivariate Cox regression analysis, preoperative ALC was an independent risk factor for cancer recurrence, along with tumor differentiation and ?-fetoprotein level. ALC ?1.64×109/L defined by ROC calculation was associated with prolonged survival (area under the curve 0.741, P<0.001). Patients with ALC ?1.64×109/L showed a mean survival of 20.2 months versus 11.6 months for patients with ALC <1.64×109/L (P<0.001). Patients were stratified into high and low groups according to ALC status. After excluding the basic parameters between groups, the 1- and 3-year recurrence rates in the high group were 20.9% and 29.5%, respectively, which were significantly lower than those of the low group (58.4% and 71.9%, respectively; P<0.001). The recurrence-free survival rates in the two groups analyzed by Kaplan–Meier curves were significantly different (P<0.001). Conclusion Preoperative ALC is a powerful prognostic factor for RHCC recurrence after thermal ablation, which suggests that maintaining a high ALC in RHCC patients might improve cancer outcomes.

Dinosaur Count and Sort  

NSDL National Science Digital Library

In this activity, learners sort and count different colored plastic dinosaurs by various attributes including tail length, whether or not the dinosaurs have horns, etc. Learners discuss the basis of their sorting, describe individual dinosaurs as well as groups and count the whole as well as subsets of the whole. This identification, sorting and grouping based on different traits (physical attributes, diet, habitat) provides a strong foundation for the development of the concept of species. The lesson plan also explains that dinosaurs lived a long time ago, but because they are no longer alive today, they are said to be extinct. Reasons for their extinction and the concept of endangered species can be explored.

High background photon counting lidar  

NASA Technical Reports Server (NTRS)

Photon counting with lidar returns is usually limited to low light levels, while wide dynamic range is achieved by counting for long times. The broad emission spectrum of inexpensive high-power semiconductor lasers makes receiver filters pass too much background light for traditional photon counting in daylight. Very high speed photon counting is possible, however, at more than 500 MHz which allows the construction of eyesafe lidar operating in the presence of bright clouds. Detector improvements are possible to count to 20 GHz producing a single shot dynamic range of ten decades.

Total and differential leucocyte counts and lymphocyte subpopulations in lymph, afferent and efferent to the supramammary lymph node, during endotoxin-induced bovine mastitis.  

PubMed

Leucocyte trafficking in afferent and efferent mammary lymph and the supramammary lymph node in cows was examined during 4 h after intramammary infusion of endotoxin from Escherichia coli. Total and differential leucocyte counts were measured in milk, blood and lymph. The proportions of CD4(+), CD8(+), major histocompatibility complex (MHC) class II(+) and IgM(+) lymphocytes were examined in the lymph and lymph node. At post-infusion hour (PIH) 4, the flow rates of both lymph fluids had increased approximately eightfold. Total leucocyte concentration increased in afferent lymph, but decreased in efferent lymph. Neutrophils increased in afferent lymph at PIH 2 and in efferent lymph and milk at PIH 4. The predominant cell type in afferent lymph shifted from lymphocyte to neutrophil while lymphocyte was still at PIH 4 the predominant type in efferent lymph. Among the lymphocytes, B cells were predominant in afferent lymph and lymph node at PIH 4 while T cells, mainly CD4(+) cells, were predominant in efferent lymph both at PIH 0 and PIH 4. The CD4 : CD8 ratio was higher in efferent lymph and the challenged lymph node than in afferent lymph and the control node, respectively. There was a significant difference in proportions of each lymphocyte subpopulation except for IgM(+) cells, between afferent and efferent lymph after infusion. According to the results, there was already during the first hours of the immune response, a non-random trafficking of neutrophils and lymphocyte subpopulations resulting in a changed distribution of cells in afferent and efferent lymph and a difference in lymphocyte reactivity between the two lymph fluids.

Making kids count.  

PubMed

Using data from the 1988 KIDS COUNT Data Book, compiled and published by The Annie E. Casey Foundation, the most recent state figures (1995) are compared with corresponding data from 1985 to assess the trends in child well-being in each state during the decade. The 10 key indicators used are taken from governmental data sources and reflect the best data available for each of the measures. Between 1985 and 1995, child well-being worsened across the country in five of the indicators, i.e., percent of low birthweight babies; rate of teen deaths by accident, homicide and suicide; teen birth rate; Juvenile Violent Crime Arrest Rate; and percent of families with children headed by a single parent. Areas of improvement include: infant mortality; child death rate; percent of teens who are high school dropouts; and percent of teens not attending school and/or not working. There was no change between 1985 and 1995 in the percent of children living in poverty. When the states are ranked by a composite of the 10 indicators of childhood well-being, a cluster of states in the South and Southwest are at or near the bottom of the rankings while the New England states and those in the upper plains are typically near the top. The states near the top have higher incomes and lower poverty rates than those near the bottom. PMID:9691356

Compton suppression gamma-counting: The effect of count rate  

USGS Publications Warehouse

Past research has shown that anti-coincidence shielded Ge(Li) spectrometers enhanced the signal-to-background ratios for gamma-photopeaks, which are situated on high Compton backgrounds. Ordinarily, an anti- or non-coincidence spectrum (A) and a coincidence spectrum (C) are collected simultaneously with these systems. To be useful in neutron activation analysis (NAA), the fractions of the photopeak counts routed to the two spectra must be constant from sample to sample to variations must be corrected quantitatively. Most Compton suppression counting has been done at low count rate, but in NAA applications, count rates may be much higher. To operate over the wider dynamic range, the effect of count rate on the ratio of the photopeak counts in the two spectra (A/C) was studied. It was found that as the count rate increases, A/C decreases for gammas not coincident with other gammas from the same decay. For gammas coincident with other gammas, A/C increases to a maximum and then decreases. These results suggest that calibration curves are required to correct photopeak areas so quantitative data can be obtained at higher count rates. ?? 1984.

Field evaluation in Chad of community usage of CD4 T lymphocyte counting by alternative single-platform flow cytometry  

PubMed Central

Background Field and community evaluation of the routine usage of CD4 T counting platforms is essential in resource-poor countries for efficient and cost-effective monitoring of HIV-infected adults and children attending health care centers. Methods We herein addressed the principal issues raised by the implementation of the single-platform, volumetric Auto40 flow cytometer (Apogee Flow Systems Ltd, Hemel Hempstead, UK) in 8 community HIV monitoring laboratories of different levels throughout Chad. This is a country with particularly difficult conditions, both in terms of climate and vast geographical territory, making the decentralization of the therapeutic management of HIV-infected patients challenging. Results The routine usage of the Auto40 flow cytometers for a period of 5 years (2008–2013) confirms the reliability and robustness of the analyzer for community-based CD4 T cell enumeration in terms of both absolute numbers and percentages to enable accurate monitoring of HIV-infected adults and children. However, our observations suggest that the Auto40 mini flow cytometer is not suitable for all laboratories as it is oversized and ultimately very expensive. Conclusion The Chad experience with the Auto40 flow cytometer suggests that its usage in resource-limited settings should be mainly reserved to reference (level 1) or district (level 2) laboratories, rather than to laboratories of health care centres (level 3).

Standardization of 241Am by digital coincidence counting, liquid scintillation counting and defined solid angle counting.  

PubMed

The nuclide (241)Am decays by alpha emission to (237)Np. Most of the decays (84.6%) populate the excited level of (237)Np with energy of 59.54 keV. Digital coincidence counting was applied to standardize a solution of (241)Am by alpha-gamma coincidence counting with efficiency extrapolation. Electronic discrimination was implemented with a pressurized proportional counter and the results were compared with two other independent techniques: Liquid scintillation counting using the logical sum of double coincidences in a TDCR array and defined solid angle counting taking into account activity inhomogeneity in the active deposit. The results show consistency between the three methods within a limit of a 0.3%. An ampoule of this solution will be sent to the International Reference System (SIR) during 2009. Uncertainties were analysed and compared in detail for the three applied methods. PMID:20031433

Association Between CD4+ T-Lymphocyte Counts and Fecal Excretion of Schistosoma mansoni Eggs in Patients Coinfected with S. mansoni and Human Immunodeficiency Virus Before and After Initiation of Antiretroviral Therapy  

PubMed Central

Previously, we have shown that persons with human immunodeficiency virus 1 (HIV-1) infection and reduced CD4+ T-lymphocyte counts excrete significantly fewer Schistosoma mansoni eggs than HIV-1–negative persons with similar intensities of schistosome infections. To determine how antiretroviral therapy (ART) might affect egg excretion, we conducted a study of HIV+ adults living in an area highly endemic for S. mansoni as they began an ART program. Fecal egg excretion and CD4+ T-lymphocyte counts were evaluated at enrollment as well as 2 and 4 weeks after initiation of ART. Fourteen individuals who were Kato–Katz-negative at enrollment subsequently started excreting S. mansoni eggs accompanied by a significant increase in CD4+ T lymphocytes (P = 0.004). Study participants who were S. mansoni egg-positive at enrollment and received both praziquantel and ART also showed significantly increased CD4+ T-lymphocyte counts compared with baseline (P < 0.0001). Our data support a role for CD4+ T lymphocytes in S. mansoni egg excretion. PMID:23669231

Differential white cell count by centrifugal microfluidics.  

SciTech Connect

We present a method for counting white blood cells that is uniquely compatible with centrifugation based microfluidics. Blood is deposited on top of one or more layers of density media within a microfluidic disk. Spinning the disk causes the cell populations within whole blood to settle through the media, reaching an equilibrium based on the density of each cell type. Separation and fluorescence measurement of cell types stained with a DNA dye is demonstrated using this technique. The integrated signal from bands of fluorescent microspheres is shown to be proportional to their initial concentration in suspension. Among the current generation of medical diagnostics are devices based on the principle of centrifuging a CD sized disk functionalized with microfluidics. These portable 'lab on a disk' devices are capable of conducting multiple assays directly from a blood sample, embodied by platforms developed by Gyros, Samsung, and Abaxis. [1,2] However, no centrifugal platform to date includes a differential white blood cell count, which is an important metric complimentary to diagnostic assays. Measuring the differential white blood cell count (the relative fraction of granulocytes, lymphocytes, and monocytes) is a standard medical diagnostic technique useful for identifying sepsis, leukemia, AIDS, radiation exposure, and a host of other conditions that affect the immune system. Several methods exist for measuring the relative white blood cell count including flow cytometry, electrical impedance, and visual identification from a stained drop of blood under a microscope. However, none of these methods is easily incorporated into a centrifugal microfluidic diagnostic platform.

Factors Associated with Late Presentation of HIV and Estimation of Antiretroviral Treatment Need according to CD4 Lymphocyte Count in a Resource-Limited Setting: Data from an HIV Cohort Study in India  

PubMed Central

We describe the CD4 lymphocyte count at HIV presentation in an HIV cohort from a rural district of India. The majority of patients were diagnosed for their HIV-related symptoms, although a sizeable proportion of women were diagnosed because of antenatal screening or for having an HIV-positive partner. Patients diagnosed of HIV for antenatal screening or having an HIV-positive sexual partner had higher CD4 lymphocyte count than patients having tuberculosis or HIV-related symptoms. The proportion of patients diagnosed with CD4 count <200 and <350 cells/mm3 were 46% and 68.7%, respectively, and these figures did not change during the five years of the study. Factors associated with late presentations were male sex, older age, not having a permanent house, and, in women, lower education and being a widow or separated. With the implementation of 2010 WHO guidelines, the number of newly diagnosed patients who will require HIV treatment will increase 13.8%. If the CD4 count threshold for initiating HIV treatment is increased from 350 to 500 cells/mm3, the number of patients in need of treatment would increase 15.7%. Therefore, new strategies for avoiding HIV late presentation are urgently needed in developing countries. PMID:22611389

Statistical Modeling of Storm Counts.  

NASA Astrophysics Data System (ADS)

A statistical model is presented of a recently compiled record of monthly extratropical storm counts for the mid-Atlantic coast of the United States for the period 1942-83. The counts are modeled as a Poisson process with nonstationary mean function. The mean function is decomposed into a secular component and a seasonal cycle. Because the form of the secular component is unknown, a nonparametric regression approach suitable for Poisson data is used to estimate it. The estimated secular component is generally constant through the 1950s, then declines through the 1970s. The estimate is found to be statistically significant. A Fourier series involving two harmonics is fit to the seasonal cycle. A preliminary check indicates that the seasonal cycle remains stable through time. Some diagnostics based on suitably defined residuals are presented that generally confirm the goodness-of-fit and distributional assumptions underlying the model.

The Making Cases Count intiative.  

PubMed

Given the challenges faced, how can homeopaths communicate the power and scope of the therapeutic system of homeopathy? Homeopaths need to communicate to patients, the public and media, other healthcare professionals, healthcare researchers, and funders of healthcare (healthcare insurers, those who commission healthcare services either in publicly funded healthcare systems such as the NHS or charities). Effective communication with these stakeholders requires information that is: (a) easily understood, (b) credible, and (c) relevant. The patient's voice is the trusted, indisputable and easily understood common ground in homeopathy. Yet, the experiences of patients are rarely heard outside the profession of homeopathy. Homeopaths are in a unique position to make these voices heard by disseminating the results of their routine practice cases incorporating their patients' voices. The 'Making Cases Count' initiative has been created in order to bring about a culture where easily understood, trusted and salient information is regularly made available to all stakeholders in homeopathy. The Making Cases Count initiative supports, guides and incentives homeopaths to collect routine data with the aim of bringing about a culture where a significant proportion of homeopaths collect routine data from their patients in a format which will then be able to be transformed (i.e. anonymised, summarised and counted). This routine data requires numbers and categories to report the behavior and the perspective of patients receiving homeopathic treatment. This can be strengthened through the use of validated outcome measures in hearing patients' voices. When transformed, this routine data will then be able to inform homeopaths and more importantly other key stakeholders. It is now time to make patient cases count. PMID:25146064

We demonstrate a compressed sensing, photon counting lidar system based on the single-pixel camera. Our technique recovers both depth and intensity maps from a single under-sampled set of incoherent, linear projections of a scene of interest at ultra-low light levels around 0.5 picowatts. Only two-dimensional reconstructions are required to image a three-dimensional scene. We demonstrate intensity imaging and depth mapping at 256 × 256 pixel transverse resolution with acquisition times as short as 3 seconds. We also show novelty filtering, reconstructing only the difference between two instances of a scene. Finally, we acquire 32 × 32 pixel real-time video for three-dimensional object tracking at 14 frames-per-second. PMID:24104293

Avian leucocyte counting using the hemocytometer  

USGS Publications Warehouse

Automated methods for counting leucocytes in avian blood are not available because of the presence of nucleated erythrocytes and thrombocytes. Therefore, total white blood cell counts are performed by hand using a hemocytometer. The Natt and Herrick and the Unopette methods are the most common stain and diluent preparations for this procedure. Replicate hemocytometer counts using these two methods were performed on blood from four birds of different species. Cells present in each square of the hemocytometer were counted. Counting cells in the corner, side, or center hemocytometer squares produced statistically equivalent results; counting four squares per chamber provided a result similar to that obtained by counting nine squares; and the Unopette method was more precise for hemocytometer counting than was the Natt and Herrick method. The Unopette method is easier to learn and perform but is an indirect process, utilizing the differential count from a stained smear. The Natt and Herrick method is a direct total count, but cell identification is more difficult.

Estimating relative abundance from count data  

USGS Publications Warehouse

Much of the available information on large-scale patterns of animal abundance is based on count surveys. The data provided by such surveys are often influenced by nuisance factors affecting the numbers of animals counted, but unrelated to population size. Temporal and spatial patterns in nuisance factors may exist, causing simple summaries of counts to give a misleading view of patterns in population size. We develop models for count data that allows the incorporation of such factors, and describe methods for estimating spatial patterns of relative abundance from counts. We carry out spatial analyses of North American Breeding Bird Survey data, in which observer ability is a nuisance parameter nested within sites. In light of evidence that new observers tend to count more birds than the observers they replace, we model observer ability as a random effect with mean depending on observer initiation year.

A radionuclide counting method, performed with the patient prone and the neck flexed, was used successfully to diagnose CSF rhinorrhea in two patients. A normal radionuclide ratio (radionuclide counts in pledget/radionuclide counts in 1-ml blood sample) was obtained in 11 normal control subjects. Significance was determined to be a ratio greater than 0.37. Use of radionuclide counting method of determining CSF rhinorrhea is recommended when other methods have failed to locate a site of leakage or when posttraumatic meningitis suggests subclinical CSF rhinorrhea.

Counting dark matter particles in LHC events  

NASA Astrophysics Data System (ADS)

We suggest trying to count the number of invisible particles produced in missing energy events at the LHC, arguing that multiple production of such particles provides evidence that they constitute stable dark matter and that counting them could yield further insights into the nature of dark matter. We propose a method to count invisible particles, based on fitting the shapes of certain transverse- or invariant-mass distributions, discuss various effects that may affect the measurement, and simulate the use of the method to count neutrinos in standard model processes and dark matter candidates in new physics processes.

Effect of counting errors on immunoassay precision  

SciTech Connect

Using mathematical analysis and computer simulation, we studied the effect of gamma scintillation counting error on two radioimmunoassays (RIAs) and an immunoradiometric assay (IRMA). To analyze the propagation of the counting errors into the estimation of analyte concentration, we empirically derived parameters for logit-log data-reduction models for assays of digoxin and triiodothyronine (RIAs) and ferritin (IRMA). The component of the analytical error attributable to counting variability, when expressed as a CV of the analyte concentration, decreased approximately linearly with the inverse of the square root of the maximum counts bound. Larger counting-error CVs were found at lower concentrations for both RIAs and the IRMA. Substantially smaller CVs for overall assay were found when the maximum counts bound progressively increased from 500 to 10,000 counts, but further increases in maximum bound counts resulted in little decrease in overall assay CV except when very low concentrations of analyte were being measured. Therefore, RIA and IRMA systems based in duplicate determinations having at least 10,000 maximum counts bound should have adequate precision, except possibly at very low concentrations.

Leukocyte nucleus segmentation and nucleus lobe counting  

PubMed Central

Background Leukocytes play an important role in the human immune system. The family of leukocytes is comprised of lymphocytes, monocytes, eosinophils, basophils, and neutrophils. Any infection or acute stress may increase or decrease the number of leukocytes. An increased percentage of neutrophils may be caused by an acute infection, while an increased percentage of lymphocytes can be caused by a chronic bacterial infection. It is important to realize an abnormal variation in the leukocytes. The five types of leukocytes can be distinguished by their cytoplasmic granules, staining properties of the granules, size of cell, the proportion of the nuclear to the cytoplasmic material, and the type of nucleolar lobes. The number of lobes increased when leukemia, chronic nephritis, liver disease, cancer, sepsis, and vitamin B12 or folate deficiency occurred. Clinical neutrophil hypersegmentation has been widely used as an indicator of B12 or folate deficiency.Biomedical technologists can currently recognize abnormal leukocytes using human eyes. However, the quality and efficiency of diagnosis may be compromised due to the limitations of the biomedical technologists' eyesight, strength, and medical knowledge. Therefore, the development of an automatic leukocyte recognition system is feasible and necessary. It is essential to extract the leukocyte region from a blood smear image in order to develop an automatic leukocyte recognition system. The number of lobes increased when leukemia, chronic nephritis, liver disease, cancer, sepsis, and vitamin B12 or folate deficiency occurred. Clinical neutrophil hypersegmentation has been widely used as an indicator of B12 or folate deficiency. Results The purpose of this paper is to contribute an automatic leukocyte nuclei image segmentation method for such recognition technology. The other goal of this paper is to develop the method of counting the number of lobes in a cell nucleus. The experimental results demonstrated impressive segmentation accuracy. Conclusions Insensitive to the variance of images, the LNS (Leukocyte Nuclei Segmentation) method functioned well to isolate the leukocyte nuclei from a blood smear image with much better UR (Under Segmentation Rate), ER (Overall Error Rate), and RDE (Relative Distance Error). The presented LC (Lobe Counting) method is capable of splitting leukocyte nuclei into lobes. The experimental results illuminated that both methods can give expressive performances. In addition, three advanced image processing techniques were proposed as weighted Sobel operator, GDW (Gradient Direction Weight), and GBPD (Genetic-based Parameter Detector). PMID:21073711

The somatic cell counts of ewes' milk were determined by an electronic particle counter (Coulter Counter). Of 1408 apparently normal milk samples, 98.2% had a somatic cell count lower than 1.0 x 10(6) cells/ml and 85.8% of 254 bacteriologically positive samples had a count higher than 1.0 x 10(6) cells/ml. Values exceeding 1.0 x 10(6) cells/ml are indicative of subclinical mastitis, if samples were collected from clinically healthy mammary glands. PMID:1777802

White blood cell differential counts in severely leukopenic samples: a comparative analysis of different solutions available in modern laboratory hematology  

PubMed Central

Background We evaluated the efficacy of white blood cell (WBC) differential counts in severely leukopenic samples by the Hematoflow method and by automated hematology analyzers and compared the results with manual counts. Methods EDTA-anticoagulated blood samples (175 samples) with WBC counts of 40-990/µL were selected. Hematoflow differential counts were performed in duplicates employing flow cytometry using the CytoDiff reagent and analysis software. Differential counts were also performed using the DxH 800 (Beckman Coulter) and XE-2100 (Sysmex) automated hematology analyzers. The sum of the manual counts by a hematology technician and a resident were used as the manual counts. Results The total analysis time and hands-on time required by the Hematoflow method were shorter than those required by manual counting. Hematoflow counts were reproducible, showed a good correlation with automated analyzers, and also showed strong correlation with manual counts (r > 0.8) in neutrophils, lymphocytes, and monocytes. None of the cases containing less than 4% blasts as analyzed by the Hematoflow method had blasts in the manual counts, but 8 cases of 21 cases (38.1%) with over 4% blasts by Hematoflow had blasts in manual counts. Conclusion Hematoflow counts of severely leukopenic samples were reproducible and showed a good correlation with manual counts in terms of neutrophil, lymphocyte, and monocyte counts. The Hematoflow method also detected the presence of blasts. Manual slide review is recommended when over 4% blasts are found by Hematoflow. PMID:25025014

Stability of prepared iodine counting standards  

SciTech Connect

This paper reports that the uses for iodine-125 in the medical sciences are increasing. I-125 is often used to label organic molecules in the performance of radioimmunoassay (RIA) procedures, and it has recently been used in the form of 800-mCi sealed sources employed by bone mineral (density) analyzers in the diagnosis of osteoporosis. These applications of the 59.9-day half-life I-125 incur the need to perform contamination surveys. In the case of the use of I-125 labeled compounds, laboratory benches and floors must be regularly checked for the presence of contamination by counting smear or wipe samples. Where multimillicurie sealed I-125 sources are employed, leak tests must be performed, again by counting smear or wipe samples. The most sensitive method readily available for the measurement of I-125 on these smear samples is scintillation counting with a thin NaI(Tl) detector. The counting system used must be calibrated for I-125 counting efficiency.

Not everything that counts can be counted: ants use multiple metrics for a single nest trait

There are claims in the literature that certain insects can count.

We show that Temnothorax albipennis ant colonies can discriminate between potential nest sites with different numbers of entrances. However, our experiments suggest that the ants use ambient light

Systemic and lung protein changes in sarcoidosis. Lymphocyte counts, gallium uptake values, and serum angiotensin-converting enzyme levels may reflect different aspects of disease activity  

SciTech Connect

BAL lymphocyte percentages, quantitated gallium-67 lung uptake, and SACE levels have all been proposed as measures of disease activity in sarcoidosis. We analyzed 32 paired sera and BAL fluids from sarcoidosis patients by high-resolution agarose electrophoresis to look for protein changes characteristic of systemic or local inflammation and compared the results with those from the above tests. Nine patients (group 1) had serum inflammatory protein changes and increased total protein, albumin, beta 1-globulin (transferrin), and gamma-globulin levels in fluid recovered by BAL. Thirteen patients (group 2) had normal protein levels in sera but abnormal protein levels in BAL specimens. Ten patients (group 3) had normal protein levels in sera and in BAL specimens. Patients in groups 1 and 2 had a disproportionate increase in beta 1-globulin (transferrin) and gamma-globulin levels in their BAL specimens. The BAL lymphocyte percentage changes paralleled the BAL protein level changes, suggesting relationships among the immunoregulatory role of these cells, increased local immunoglobulin synthesis, and the pathogenesis of altered alveolar permeability. Gallium-67 uptake was highest in patients with serum inflammatory protein changes. Thus, systemic inflammation may facilitate pulmonary gallium-67 uptake, possibly by changes in BAL fluid or serum transferrin saturation and/or kinetics. SACE levels showed no relationship to changes in the levels of serum or BAL proteins. These data suggest that the various proposed measures of disease activity reflect different aspects of inflammation in sarcoidosis.

Fast box-counting algorithm on GPU.  

PubMed

The box-counting algorithm is one of the most widely used methods for calculating the fractal dimension (FD). The FD has many image analysis applications in the biomedical field, where it has been used extensively to characterize a wide range of medical signals. However, computing the FD for large images, especially in 3D, is a time consuming process. In this paper we present a fast parallel version of the box-counting algorithm, which has been coded in CUDA for execution on the Graphic Processing Unit (GPU). The optimized GPU implementation achieved an average speedup of 28 times (28×) compared to a mono-threaded CPU implementation, and an average speedup of 7 times (7×) compared to a multi-threaded CPU implementation. The performance of our improved box-counting algorithm has been tested with 3D models with different complexity, features and sizes. The validity and accuracy of the algorithm has been confirmed using models with well-known FD values. As a case study, a 3D FD analysis of several brain tissues has been performed using our GPU box-counting algorithm. PMID:22917763

Quantum abacus for counting and factorizing numbers  

SciTech Connect

We generalize the binary quantum counting algorithm of Lesovik, Suslov, and Blatter [Phys. Rev. A 82, 012316 (2010)] to higher counting bases. The algorithm makes use of qubits, qutrits, and qudits to count numbers in a base-2, base-3, or base-d representation. In operating the algorithm, the number ncounting task naturally leads to the shift operation and an algorithm based on the quantum Fourier transformation. We discuss possible implementations of the algorithm using quantum spin-d systems, d-well systems, and their emulation with spin-1/2 or double-well systems. We establish the analogy between our counting algorithm and the phase estimation algorithm and make use of the latter's performance analysis in stabilizing our scheme. Applications embrace a quantum metrological scheme to measure voltage (an analog to digital converter) and a simple procedure to entangle multiparticle states.

Count rate limitations for pulse-counting instrumentation in pulsed accelerator fields.  

PubMed

This paper discusses various concepts involved in the counting losses of pulse-counting health physics instrumentation when used within the pulsed radiation environments of typical accelerator fields in order to preestablish appropriate limitations in use. Discussed are the "narrow" pulse and the "wide" pulse cases, the special effect of neutron moderating assemblies, and the effect of pulse fine microstructure on the counting losses of the pulse-counting instrumentation. In the narrow-pulse case, the accelerator pulse width is less than or equal to the instrument's dead time; whereas in the wide-pulse case, the accelerator pulse width is significantly longer than the instrument's dead time. Examples are provided that highlight the various concepts and limitations. PMID:22134075

It proposes a modified zero-inflated count data model where the probability of an extra zero is derived from an underlying duration model with Weibull hazard rate. The new model is compared to the standard Poisson model with logit zero inflation in an application to the effect of treatment with thiotepa on the number of new bladder tumors. PMID:24003010

Low level counting from meteorites to neutrinos  

SciTech Connect

The development in low level counting at Heidelberg with NaI(Tl) crystals, proportional counters and Germanium detectors is reviewed throughout the course of almost 40 years of experience. Research subjects changed from cosmogenic radionuclides in meteorites to solar neutrinos and double beta decay. Driven by screening measurements for these rare event experiments, the sensitivity in single gamma counting has gained almost 3 orders of magnitude. With Ge spectrometry the {mu}Bq/kg range is now accessible. It is discussed how further improvements can be realized. There is potential to reach a sensitivity at the level of 10 to 100 nBq/kg for cryogenic liquid type Gespectroscopy, a technique which the next generation 76Ge double beta decay experiment GERDA is based on.

We outline an algorithm for the quantum counting problem using adiabatic quantum computation (AQC). We show that the mechanism of quantum-adiabatic evolution may be utilized toward estimating the number of solutions to a problem, and not only to find them. Using local adiabatic evolution, a process in which the adiabatic procedure is performed at a variable rate, the problem of counting the number of marked items in an unstructured database is solved quadratically faster than the corresponding classical algorithm. The above algorithm provides further evidence for the potentially powerful capabilities of AQC as a paradigm for more efficient problem solving on a quantum computer, and may be used as the basis for solving more sophisticated problems.

Inventory verification measurements using neutron multiplicity counting  

SciTech Connect

This paper describes a series of neutron multiplicity measurements of large plutonium samples at the Los Alamos Plutonium Facility. The measurements were corrected for bias caused by neutron energy spectrum shifts and nonuniform multiplication, and are compared with calorimetry/isotopics. The results show that multiplicity counting can increase measurement throughput and yield good verification results for some inventory categories. The authors provide recommendations on the future application of the technique to inventory verification.

Photon counting ladar work at FOI, Sweden  

NASA Astrophysics Data System (ADS)

Photon counting techniques using direct detection has recently gained considerable interest within the laser radar community. The high sensitivity is of special importance to achieve high area coverage in surveillance and mapping applications and long range with compact systems for imaging, profiling and ranging. New short pulse lasers including the super continuum laser is of interest for active spectral imaging. A special technique in photon counting is the "time correlated single photon counting" (TCSPC). This can be utilized together with short pulse (ps) lasers to achieve very high range resolution and accuracy (mm level). Low average power lasers in the mW range enables covert operation with respect to present laser warning technology. By analyzing the return waveform range and shape information from the target can be extracted. By scanning the beam high resolution 3D images are obtained. At FOI we have studied the TCSPC with respect to range profiling and imaging. Limitations due to low SNR and dwell times are studied in conjunction with varying daylight background and atmospheric turbulence. Examples of measurements will be presented and discussed with respect to some system applications.

Curves, dynamical systems, and weighted point counting.  

PubMed

Suppose X is a (smooth projective irreducible algebraic) curve over a finite field k. Counting the number of points on X over all finite field extensions of k will not determine the curve uniquely. Actually, a famous theorem of Tate implies that two such curves over k have the same zeta function (i.e., the same number of points over all extensions of k) if and only if their corresponding Jacobians are isogenous. We remedy this situation by showing that if, instead of just the zeta function, all Dirichlet L-series of the two curves are equal via an isomorphism of their Dirichlet character groups, then the curves are isomorphic up to "Frobenius twists", i.e., up to automorphisms of the ground field. Because L-series count points on a curve in a "weighted" way, we see that weighted point counting determines a curve. In a sense, the result solves the analogue of the isospectrality problem for curves over finite fields (also know as the "arithmetic equivalence problem"): It states that a curve is determined by "spectral" data, namely, eigenvalues of the Frobenius operator of k acting on the cohomology groups of all ?-adic sheaves corresponding to Dirichlet characters. The method of proof is to show that this is equivalent to the respective class field theories of the curves being isomorphic as dynamical systems, in a sense that we make precise. PMID:23716684

Homeostatic regulation of blood neutrophil counts  

PubMed Central

Neutrophil counts in blood are determined by the differentiation and proliferation of precursor cells in the bone marrow, release of mature neutrophils into the blood, margination in organs like the lung and spleen, and transmigration through the endothelial lining followed by neutrophil apoptosis and uptake by phagocytes. This brief review summarizes how the regulation of neutrophil production by G-CSF is in part controlled by IL-17 and IL-23. Neutrophils are retained in the bone marrow through interaction of CXCL12 with its receptor CXCR4. The relevance of this mechanism is illustrated by rare diseases in which disrupting the desensitization of CXCR4 results in neutrophil accumulation in the bone marrow. Although blood neutrophil numbers in inbred mouse strains and individual human subjects are tightly controlled, the large variation of blood neutrophil counts among outbred populations suggests genetic control. One example is benign ethnic neutropenia, which is found in about 5% of African Americans. Reduced and elevated neutrophil counts, even within the normal range, are associated with excess all-cause mortality. PMID:18832668

A mind you can count on: validating breath counting as a behavioral measure of mindfulness  

PubMed Central

Mindfulness practice of present moment awareness promises many benefits, but has eluded rigorous behavioral measurement. To date, research has relied on self-reported mindfulness or heterogeneous mindfulness trainings to infer skillful mindfulness practice and its effects. In four independent studies with over 400 total participants, we present the first construct validation of a behavioral measure of mindfulness, breath counting. We found it was reliable, correlated with self-reported mindfulness, differentiated long-term meditators from age-matched controls, and was distinct from sustained attention and working memory measures. In addition, we employed breath counting to test the nomological network of mindfulness. As theorized, we found skill in breath counting associated with more meta-awareness, less mind wandering, better mood, and greater non-attachment (i.e., less attentional capture by distractors formerly paired with reward). We also found in a randomized online training study that 4 weeks of breath counting training improved mindfulness and decreased mind wandering relative to working memory training and no training controls. Together, these findings provide the first evidence for breath counting as a behavioral measure of mindfulness. PMID:25386148

Modelling bivariate count series with excess zeros.  

PubMed

Bivariate time series of counts with excess zeros relative to the Poisson process are common in many bioscience applications. Failure to account for the extra zeros in the analysis may result in biased parameter estimates and misleading inferences. A class of bivariate zero-inflated Poisson autoregression models is presented to accommodate the zero-inflation and the inherent serial dependency between successive observations. An autoregressive correlation structure is assumed in the random component of the compound regression model. Parameter estimation is achieved via an EM algorithm, by maximizing an appropriate log-likelihood function to obtain residual maximum likelihood estimates. The proposed method is applied to analyze a bivariate series from an occupational health study, in which the zero-inflated injury count events are classified as either musculoskeletal or non-musculoskeletal in nature. The approach enables the evaluation of the effectiveness of a participatory ergonomics intervention at the population level, in terms of reducing the overall incidence of lost-time injury and a simultaneous decline in the two mean injury rates.

Photon Counts Statistics in Leukocyte Cell Dynamics  

NASA Astrophysics Data System (ADS)

In the present experiment ultra-weak photon emission/ chemiluminescence from isolated neutrophils was recorded. It is associated with the production of reactive oxygen species (ROS) in the "respiratory burst" process which can be activated by PMA (Phorbol 12-Myristate 13-Acetate). Commonly, the reaction is demonstrated utilizing the enhancer luminol. However, with the use of highly sensitive photomultiplier equipment it is also recorded without enhancer. In that case, it can be hypothesized that photon count statistics may assist in understanding the underlying metabolic activity and cooperation of these cells. To study this hypothesis leukocytes were stimulated with PMA and increased photon signals were recorded in the quasi stable period utilizing Fano factor analysis at different window sizes. The Fano factor is defined by the variance over the mean of the number of photon within the observation time. The analysis demonstrated that the Fano factor of true signal and not of the surrogate signals obtained by random shuffling increases when the window size increased. It is concluded that photon count statistics, in particular Fano factor analysis, provides information regarding leukocyte interactions. It opens the perspective to utilize this analytical procedure in (in vivo) inflammation research. However, this needs further validation.

Analysis of Parasite and Other Skewed Counts  

PubMed Central

Objective To review methods for the statistical analysis of parasite and other skewed count data. Methods Statistical methods for skewed count data are described and compared, with reference to those used over a ten year period of Tropical Medicine and International Health. Two parasitological datasets are used for illustration. Results Ninety papers were identified, 89 with descriptive and 60 with inferential analysis. A lack of clarity is noted in identifying measures of location, in particular the Williams and geometric mean. The different measures are compared, emphasizing the legitimacy of the arithmetic mean for skewed data. In the published papers, the t test and related methods were often used on untransformed data, which is likely to be invalid. Several approaches to inferential analysis are described, emphasizing 1) non-parametric methods, while noting that they are not simply comparisons of medians, and 2) generalized linear modelling, in particular with the negative binomial distribution. Additional methods, such as the bootstrap, with potential for greater use are described. Conclusions Clarity is recommended when describing transformations and measures of location. It is suggested that non-parametric methods and generalized linear models are likely to be sufficient for most analyses. PMID:22943299

Automated Counting of Particles To Quantify Cleanliness  

NASA Technical Reports Server (NTRS)

A machine vision system, similar to systems used in microbiological laboratories to count cultured microbes, has been proposed for quantifying the cleanliness of nominally precisely cleaned hardware by counting residual contaminant particles. The system would include a microscope equipped with an electronic camera and circuitry to digitize the camera output, a personal computer programmed with machine-vision and interface software, and digital storage media. A filter pad, through which had been aspirated solvent from rinsing the hardware in question, would be placed on the microscope stage. A high-resolution image of the filter pad would be recorded. The computer would analyze the image and present a histogram of sizes of particles on the filter. On the basis of the histogram and a measure of the desired level of cleanliness, the hardware would be accepted or rejected. If the hardware were accepted, the image would be saved, along with other information, as a quality record. If the hardware were rejected, the histogram and ancillary information would be recorded for analysis of trends. The software would perceive particles that are too large or too numerous to meet a specified particle-distribution profile. Anomalous particles or fibrous material would be flagged for inspection.

Language and counting: Some recent results  

NASA Astrophysics Data System (ADS)

It has long been recognised that the language of mathematics is an important variable in the learning of mathematics, and there has been useful work in isolating and describing the linkage. Steffe and his co-workers at Georgia, for example, (Steffe, von Glasersfeld, Richardson and Cobb, 1983) have suggested that young children may construct verbal countable items to count objects which are hidden from their view. Although there has been a surge of research interest in counting and early childhood mathematics, and in cultural differences in mathematics attainment, there has been little work reported on the linkage between culture as exemplified by language, and initial concepts of numeration. This paper reports on some recent clinical research with kindergarten children of European and Asian background in Australia and America. The research examines the influence that number naming grammar appears to have on young children's understandings of two-digit numbers and place value. It appears that Transparent Standard Number Word Sequences such as Japanese, Chinese and Vietnamese which follow the numerical representation pattern by naming tens and units in order ("two tens three"), may be associated with distinctive place value concepts which may support sophisticated mental algorithms.

It's not the pixel count, you fool  

NASA Astrophysics Data System (ADS)

The first thing a "marketing guy" asks the digital camera engineer is "how many pixels does it have, for we need as many mega pixels as possible since the other guys are killing us with their "umpteen" mega pixel pocket sized digital cameras. And so it goes until the pixels get smaller and smaller in order to inflate the pixel count in the never-ending pixel-wars. These small pixels just are not very good. The truth of the matter is that the most important feature of digital cameras in the last five years is the automatic motion control to stabilize the image on the sensor along with some very sophisticated image processing. All the rest has been hype and some "cool" design. What is the future for digital imaging and what will drive growth of camera sales (not counting the cell phone cameras which totally dominate the market in terms of camera sales) and more importantly after sales profits? Well sit in on the Dark Side of Color and find out what is being done to increase the after sales profits and don't be surprised if has been done long ago in some basement lab of a photographic company and of course, before its time.

Quality Counts 2002: Building Blocks for Success  

NSDL National Science Digital Library

This year's Quality Counts report (last mentioned in the January 12, 2001 Scout Report) focuses on the importance of high quality learning experiences for children prior to their K-12 school years. The benefits of offering quality education at this early point can be substantial; children perform with better cognitive skills during later educational stages. Not simply an endorsement of improved standards and programs, the report outlines the current state of affairs with supporting statistics and documentation for each state and the District of Columbia. The report examines tangible issues such as adequate pay for educators, evaluation criteria and measurement tools, and each state's "commitment to Kindergarten." The format of this report is much enhanced from prior publications. An Interactive data search, Excel and .pdf data tables, Web-only testing data (e.g., the table "Grade-by-Grade Testing Policies" is available online only), and inclusion of "new indicators of several school-quality categories" are all new features with the 2002 report. This report, as are all the Quality Counts Reports from Education Week and the Pew Charitable Trusts, is a thoughtful read for anyone concerned with education.

Point count length and detection of forest neotropical migrant birds  

USGS Publications Warehouse

Comparisons of bird abundances among years or among habitats assume that the rates at which birds are detected and counted are constant within species. We use point count data collected in forests of the Mid-Atlantic states to estimate detection probabilities for Neotropical migrant bird species as a function of count length. For some species, significant differences existed among years or observers in both the probability of detecting the species and in the rate at which individuals are counted. We demonstrate the consequence that variability in species' detection probabilities can have on estimates of population change, and discuss ways for reducing this source of bias in point count studies.

Controlling for varying effort in count surveys --an analysis of Christmas Bird Count Data  

USGS Publications Warehouse

The Christmas Bird Count (CBC) is a valuable source of information about midwinter populations of birds in the continental U.S. and Canada. Analysis of CBC data is complicated by substantial variation among sites and years in effort expended in counting; this feature of the CBC is common to many other wildlife surveys. Specification of a method for adjusting counts for effort is a matter of some controversy. Here, we present models for longitudinal count surveys with varying effort; these describe the effect of effort as proportional to exp(B effortp), where B and p are parameters. For any fixed p, our models are loglinear in the transformed explanatory variable (effort)p and other covariables. Hence we fit a collection of loglinear models corresponding to a range of values of p, and select the best effort adjustment from among these on the basis of fit statistics. We apply this procedure to data for six bird species in five regions, for the period 1959-1988.

Number Counts and Dynamical Vacuum Cosmologies  

E-print Network

We study non-linear structure formation in an interacting model of the dark sector of the Universe in which the dark energy density decays linearly with the Hubble parameter, $\\rho_{\\Lambda} \\propto H$, leading to a constant-rate creation of cold dark matter. We derive all relevant expressions to calculate the mass function and the cluster number density using the Sheth-Torman formalism and show that the effect of the interaction process is to increase the number of bound structures of large masses ($M \\gtrsim 10^{14} M_{\\odot}h^{-1}$) when compared to the standard $\\Lambda$CDM model. Since these models are not reducible to each other, this number counts signature can in principle be tested in future surveys.

Comparison of epifluorescent viable bacterial count methods  

NASA Technical Reports Server (NTRS)

Two methods, the 2-(4-Iodophenyl) 3-(4-nitrophenyl) 5-phenyltetrazolium chloride (INT) method and the direct viable count (DVC), were tested and compared for their efficiency for the determination of the viability of bacterial populations. Use of the INT method results in the formation of a dark spot within each respiring cell. The DVC method results in elongation or swelling of growing cells that are rendered incapable of cell division. Although both methods are subjective and can result in false positive results, the DVC method is best suited to analysis of waters in which the number of different types of organisms present in the same sample is assumed to be small, such as processed waters.

On Matrices, Automata, and Double Counting  

NASA Astrophysics Data System (ADS)

Matrix models are ubiquitous for constraint problems. Many such problems have a matrix of variables M, with the same constraint defined by a finite-state automaton A on each row of M and a global cardinality constraint gcc on each column of M. We give two methods for deriving, by double counting, necessary conditions on the cardinality variables of the gcc constraints from the automaton A. The first method yields linear necessary conditions and simple arithmetic constraints. The second method introduces the cardinality automaton, which abstracts the overall behaviour of all the row automata and can be encoded by a set of linear constraints. We evaluate the impact of our methods on a large set of nurse rostering problem instances.

Counting whales in a challenging, changing environment.  

PubMed

Estimating abundance of Antarctic minke whales is central to the International Whaling Commission's conservation and management work and understanding impacts of climate change on polar marine ecosystems. Detecting abundance trends is problematic, in part because minke whales are frequently sighted within Antarctic sea ice where navigational safety concerns prevent ships from surveying. Using icebreaker-supported helicopters, we conducted aerial surveys across a gradient of ice conditions to estimate minke whale density in the Weddell Sea. The surveys revealed substantial numbers of whales inside the sea ice. The Antarctic summer sea ice is undergoing rapid regional change in annual extent, distribution, and length of ice-covered season. These trends, along with substantial interannual variability in ice conditions, affect the proportion of whales available to be counted by traditional shipboard surveys. The strong association between whales and the dynamic, changing sea ice requires reexamination of the power to detect trends in whale abundance or predict ecosystem responses to climate change.

[Every life counts : suicide by anesthetists].  

PubMed

This article has its roots in the consternation of head anesthetists over the loss of colleagues. Anesthesia, intensive care medicine, emergency medicine and pain therapy has lost too many first class colleagues through suicide, addiction, severe depression and other causes. It is time to direct attention not exclusively to patients but also to apply an important occupational principle in the rescue service and intensive care medicine to the profession of anesthetists: Every life counts! The following article supplies information on the frequency, methods and possible reasons for suicide by physicians and suggestions for the prevention of suicide as well as treatment of physicians who are at risk of suicide will be presented.

Rapid count of microbial cells in dialysate.  

PubMed

An apparatus for the non-culture method (NCM) of microbial cell count was formerly developed and named a bioplorer. The bioplorer NCM is based on the double staining of cells with 4', 6-diamidino-2-phenylindole (DAPI) and propidium iodide (PI) and the automatic analysis of their fluorescent microscopic images. Viable cells can be stained with DAPI, while dead cells can be stained with DAPI and PI. In this study, the bioplorer NCM has been applied to the dialysate. The viable and dead cells in dialysate could be counted within 20 min. The detection limit expressed by log(10)[cells/100 mL] was 2.0. When cell-spiked dialysate samples containing prescribed number of Bacillus subtilis cells were assayed, the numbers of cells determined by the bioplorer NCM (N(VIA)(NCM)) and a conventional culture method (CM) on R2A medium (N(VIA)(R2A-CM)) were similar in the range of 2.6-4.6 within the 95% confidence interval (NCM-CM equivalent range). When test solutions sampled from a practical facility in a hospital were assayed, N(VIA)(NCM) was greater than, but comparable to, N(VIA)(R2A-CM). The endotoxin (ET) in the test samples were assayed as well using a test kit for limulus amoebocyte lysate assay. The results of microbial cells and ET concentration indicated that the dialysate supplying line was clean and well maintained. The bioplorer NCM can determine if the microbial contamination of dialysate supplying facilities is greater than 2.6 (398 cells/100 mL). PMID:17845395

Statistical mapping of count survey data  

USGS Publications Warehouse

We apply a Poisson mixed model to the problem of mapping (or predicting) bird relative abundance from counts collected from the North American Breeding Bird Survey (BBS). The model expresses the logarithm of the Poisson mean as a sum of a fixed term (which may depend on habitat variables) and a random effect which accounts for remaining unexplained variation. The random effect is assumed to be spatially correlated, thus providing a more general model than the traditional Poisson regression approach. Consequently, the model is capable of improved prediction when data are autocorrelated. Moreover, formulation of the mapping problem in terms of a statistical model facilitates a wide variety of inference problems which are cumbersome or even impossible using standard methods of mapping. For example, assessment of prediction uncertainty, including the formal comparison of predictions at different locations, or through time, using the model-based prediction variance is straightforward under the Poisson model (not so with many nominally model-free methods). Also, ecologists may generally be interested in quantifying the response of a species to particular habitat covariates or other landscape attributes. Proper accounting for the uncertainty in these estimated effects is crucially dependent on specification of a meaningful statistical model. Finally, the model may be used to aid in sampling design, by modifying the existing sampling plan in a manner which minimizes some variance-based criterion. Model fitting under this model is carried out using a simulation technique known as Markov Chain Monte Carlo. Application of the model is illustrated using Mourning Dove (Zenaida macroura) counts from Pennsylvania BBS routes. We produce both a model-based map depicting relative abundance, and the corresponding map of prediction uncertainty. We briefly address the issue of spatial sampling design under this model. Finally, we close with some discussion of mapping in relation to habitat structure. Although our models were fit in the absence of habitat information, the resulting predictions show a strong inverse relation with a map of forest cover in the state, as expected. Consequently, the results suggest that the correlated random effect in the model is broadly representing ecological variation, and that BBS data may be generally useful for studying bird-habitat relationships, even in the presence of observer errors and other widely recognized deficiencies of the BBS.

Submillimeter Galaxy Number Counts in a Semi-analytic Model: the ``Count Matching" Approach  

NASA Astrophysics Data System (ADS)

Recent interferometric observations of the Extended Chandra Deep Field South show that the brightest sub-millimeter galaxies (SMGs) detected by single-dish telescopes are comprised by emission from multiple fainter sources. With the aim of exploring the properties of SMGs, and in analogy to the now-standard abundance matching approach, we perform a ``Count Matching" approach through light-cones drawn from a semi-analytic model. We choose various physical galaxy properties given by the model as proxies for their sub-millimeter fluxes, assuming a monotonic relationship so that the combined LABOCA plus bright-end ALMA observed number counts are reproduced. After turning the catalogs of galaxy positions and fluxes given by the different proxies into sub-millimeter maps, we perform a source extraction. With this we study the effects of the observational process in the recovered counts, as well as the galaxy properties derived from the detected sources for each proxy. Comparing the recovered redshift, stellar mass and host halo mass distributions with observational data, the best proxy can be found.

The Cherenkov counting efficiency varies strongly with color quenching, thus correction curves must be used to obtain correct results. The external (152)Eu source of a Quantulus 1220 liquid scintillation counting (LSC) system was used to obtain a quench indicative parameter based on spectra area ratio. A color quench correction curve for aqueous samples containing (90)Sr/(90)Y was prepared. The main advantage of this method over the common spectra indicators is its usefulness also for low level Cherenkov counting. PMID:19249219

Reconstructing a Partially Observed Record of Tropical Cyclone Counts.  

NASA Astrophysics Data System (ADS)

An approach to reconstructing a partially observed annual time series of tropical cyclone counts is presented. The approach is based on a simple model of the time series of true counts and on a simple model of the way in which this time series is observed through time. The approach is applied to a record of observed tropical cyclone counts for the Australian region for the period 1910-88. Some diagnostics are presented that indicate the model performs fairly well at reproducing the behavior of the observed counts.

Coincident count rates in absorbing dielectric media  

E-print Network

A study of the effects of absorption on the nonlinear process of parametric down conversion is presented. Absorption within the nonlinear medium is accounted for by employing the framework of macroscopic QED and the Green tensor quantization of the electromagnetic field. An effective interaction Hamiltonian, which describes the nonlinear interaction of the electric field and the linear noise polarization field, is used to derive the quantum state of the light leaving a nonlinear crystal. The signal and idler modes of this quantum state are found to be a superpositions of the electric and noise polarization fields. Using this state, the expression for the coincident count rates for both Type I and Type II conversion are found. The nonlinear interaction with the noise polarization field were shown to cause an increase in the rate on the order of 10^{-12} for absorption of 10% per cm. This astonishingly small effect is found to be negligible compared to the decay caused by linear absorption of the propagating modes. From the expressions for the biphoton amplitude it can be seen the maximally entangled states can still be produced even in the presence of strong absorption.

Estimating resource selection with count data  

PubMed Central

Resource selection functions (RSFs) are typically estimated by comparing covariates at a discrete set of “used” locations to those from an “available” set of locations. This RSF approach treats the response as binary and does not account for intensity of use among habitat units where locations were recorded. Advances in global positioning system (GPS) technology allow animal location data to be collected at fine spatiotemporal scales and have increased the size and correlation of data used in RSF analyses. We suggest that a more contemporary approach to analyzing such data is to model intensity of use, which can be estimated for one or more animals by relating the relative frequency of locations in a set of sampling units to the habitat characteristics of those units with count-based regression and, in particular, negative binomial (NB) regression. We demonstrate this NB RSF approach with location data collected from 10 GPS-collared Rocky Mountain elk (Cervus elaphus) in the Starkey Experimental Forest and Range enclosure. We discuss modeling assumptions and show how RSF estimation with NB regression can easily accommodate contemporary research needs, including: analysis of large GPS data sets, computational ease, accounting for among-animal variation, and interpretation of model covariates. We recommend the NB approach because of its conceptual and computational simplicity, and the fact that estimates of intensity of use are unbiased in the face of temporally correlated animal location data.

Advanced Reference Counting Pointers for Better Performance  

NASA Technical Reports Server (NTRS)

A computer program implements reference counting pointers (RCPs) that are lock-free, thread-safe, async-safe, and operational on a multiprocessor computer. RCPs are powerful and convenient means of managing heap memory in C++ software. Most prior RCP programs use locks to ensure thread safety and manage concurrency. The present program was developed in a continuing effort to explore ways of using the C++ programming language to develop safety-critical and mission- critical software. This effort includes exploration of lock-free algorithms because they offer potential to avoid some costly and difficult verification problems. Unlike previously published RCP software, the present program does not use locks (meaning that no thread can block progress on another thread): Instead, this program implements algorithms that exploit capabilities of central-processing- unit hardware so as to avoid locks. Once locks are eliminated, it becomes possible to realize the other attributes mentioned in the first sentence. In addition to the abovementioned attributes, this program offers several advantages over other RCP programs that use locks: It is smaller (and, hence, is faster and uses less memory), it is immune to priority inversion, and there is no way for it to cause a C++ exception.

Counting colorings of a regular graph  

E-print Network

At most how many (proper) q-colorings does a regular graph admit? Galvin and Tetali conjectured that among all n-vertex, d-regular graphs with 2d|n, none admits more q-colorings than the disjoint union of n/2d copies of the complete bipartite graph K_{d,d}. In this note we give asymptotic evidence for this conjecture, giving an upper bound on the number of proper q-colorings admitted by an n-vertex, d-regular graph of the form a^n b^{n(1+o(1))/d} (where a and b depend on q and where o(1) goes to 0 as d goes to infinity) that agrees up to the o(1) term with the count of q-colorings of n/2d copies of K_{d,d}. An auxiliary result is an upper bound on the number of colorings of a regular graph in terms of its independence number. For example, we show that for all even q and fixed \\epsilon > 0 there is \\delta=\\delta(\\epsilon,q) such that the number of proper q-colorings admitted by an n-vertex, d-regular graph with no independent set of size n(1-\\epsilon)/2 is at most (a-\\delta)^n.

Accuracy and reliability of naevus self-counts.  

PubMed

A high number of melanocytic naevi is one of the major risk factors for cutaneous melanoma. Therefore, counting the number of acquired naevi could be a useful strategy to identify individuals at an increased risk for targeted skin cancer screening. The aim of this study was to assess agreement between naevus self-counts and counts of trained examiners as well as to analyse potential determinants of the magnitude of agreement. In a large cross-sectional survey (n=1772), university students counted their naevi on both arms and were additionally examined by specifically trained examiners in a mutually blinded manner. Further data on other melanoma risk factors such as skin phototype, hair colour or freckling were collected by a questionnaire. The relative difference between the two naevus counts and the ratio of the counts were calculated to quantify agreement. Regression modelling was performed to identify independent determinants of agreement. The overall agreement was moderate, with participants counting on average 14% more naevi than the examiners. In terms of the potential determinants associated with agreement, skin type and medical education showed a strong effect. The difference in naevus counts was significantly larger for individuals with lighter skin types compared with those with a dark skin (Fitzpatrick type IV), and medical students yielded a naevus count more similar to the examiner's count than nonmedical students. Naevus self-counts can only provide a rough estimate of the number of naevi, but may not be accurate enough to reliably identify a high-risk group for melanoma screening, especially in individuals with light skin types.

Full counting statistics of persistent current  

NASA Astrophysics Data System (ADS)

We develop a method for the calculation of charge-transfer statistics of persistent current in nanostructures in terms of the cumulant generating function (CGF) of transferred charge. We consider a simply connected one-dimensional system (a wire) and develop a procedure for the calculation of the CGF of persistent currents when the wire is closed into a ring via a weak link. For the noninteracting system we derive a general formula in terms of the two-particle Green's functions. We show that, contrary to the conventional tunneling contacts, the resulting cumulant generating function has a doubled periodicity as a function of the counting field. We apply our general formula to short tight-binding chains and show that the resulting CGF perfectly reproduces the known evidence for the persistent current. Its second cumulant turns out to be maximal at the switching points and vanishes identically at zero temperature. Furthermore, we apply our formalism for a computation of the charge-transfer statistics of genuinely interacting systems. First we consider a ring with an embedded Anderson impurity and employing a self-energy approximation find an overall suppression of persistent current as well as of its noise. Finally, we compute the charge-transfer statistics of a double-quantum-dot system in the deep Kondo limit using an exact analytical solution of the model at the Toulouse point. We analyze the behavior of the resulting cumulants and compare them with those of a noninteracting double-quantum-dot system and find several pronounced differences, which can be traced back to interaction effects.

Automation of spot counting in interphase cytogenetics using brightfield microscopy  

SciTech Connect

In situ hybridization techniques allow the enumeration of chromosomal abnormalities and form a great potential for many clinical applications. Although the use of fluorescent labels is preferable regarding sensitivity and colormultiplicity, chromogenic labels can provide an excellent alternative in relatively simple situations, e.g., where it is sufficient to use a centromere-specific probe to detect abnormalities of one specific chromosome. When the frequency of chromosomal aberrations is low, several hundreds or even thousands of cells have to be evaluated to achieve sufficient statistical confidence. Since manual counting is tedious, fatiguing, and time consuming, automation can assist to process the slides more efficiently. Therefore, a system has been developed for automated spot counting using brightfield microscopy. This paper addresses both the hardware system aspects and the software image analysis algorithms for nuclei and spot detection. As a result of the automated slide analysis the system provides the frequency spot distribution of the selected cells. The automatic classification can, however, be overruled by human interaction, since each individual cell is stored in a gallery and can be relocated for visual inspection. With this system a thousand cells can be automatically analyzed in approximately 10 min, while an extra 5-10 min is necessary for visual evaluation. The performance of the system was analyzed using a model system for trisomy consisting of a mixture of male and female lymphocytes hybridized with probes for chromosomes 7 and Y. The sensitivity for trisomy detection in the seeding experiment was such that a frequency of 3% trisomic cells could be picked up automatically as being abnormal according to the multiple proportion test, while trisomy as low as 1.5% could be detected after interaction. 26 refs., 4 figs., 4 tabs.

Lower white blood cell counts in elite athletes training for highly aerobic sports.  

PubMed

White cell counts at rest might be lower in athletes participating in selected endurance-type sports. Here, we analysed blood tests of elite athletes collected over a 10-year period. Reference ranges were established for 14 female and 14 male sports involving 3,679 samples from 937 females and 4,654 samples from 1,310 males. Total white blood cell counts and counts of neutrophils, lymphocytes and monocytes were quantified. Each sport was scaled (1-5) for its perceived metabolic stress (aerobic-anaerobic) and mechanical stress (concentric-eccentric) by 13 sports physiologists. Substantially lower total white cell and neutrophil counts were observed in aerobic sports of cycling and triathlon (~16% of test results below the normal reference range) compared with team or skill-based sports such as water polo, cricket and volleyball. Mechanical stress of sports had less effect on the distribution of cell counts. The lower white cell counts in athletes in aerobic sports probably represent an adaptive response, not underlying pathology. PMID:20640439

Photon Counting Airborne Laser Swath Mapping  

NASA Astrophysics Data System (ADS)

During the past decade airborne laser swath mapping (ALSM) has brought topographic mapping to the forefront of geodesy. ALSM has made it possible, for the first time, to study natural geo-surficial processes on spatial scales extending from meters to hundreds of kilometers, all in a consistent geodetic frame of reference. The conventional approach to ALSM has been to use lasers with enough energy per pulse, and optics with large enough collecting areas, to obtain returns of thousands of photons per shot. This approach minimizes the impact of spurious range values caused by noise, such as background solar radiation and sensor thermal noise, but also constrains the minimum size, weight and power consumption of the hardware. Current systems typically operate at rates approaching 100,000 pulses per second, and another order of magnitude increase would be needed to provide contiguous coverage with a spatial resolution of 30 cm or better. This high signal-to-noise ratio approach affords little scalability for significantly downsizing the hardware, or reducing the costs. University of Florida (UF) researchers are developing an ALSM unit based on a different paradigm, which we refer to as photon counting ALSM, or simply PC-ALSM. The approach is to transmit relatively low energy laser pulses, and to illuminate a surface `patch' about an order of magnitude larger than the typical footprint of a conventional ALSM system. The returning signal will have far fewer photons per unit area of the receive optics, making it more difficult to discriminate between return signal and noise. If a single channel detector were used, the spatial resolution would also be degraded. However, by using a multi-channel photomultiplier tube to detect the returns, the surface patch can be divided into an array of groundals, and by using a multi-stop timing system false ranges can be filtered out of the data during post flight processing. Researchers at NASA GSFC have already tested a first generation system based on this new paradigm, operated from a high altitude aircraft, to develop a satellite based instrument. Details of the preliminary UF design for a second generation system that will operate from a light aircraft flying less than 1000 meters above local ground level and providing contiguous coverage of the terrain with 30 cm spatial resolution will be presented.

You can count on the motor cortex: finger counting habits modulate motor cortex activation evoked by numbers.  

PubMed

The embodied cognition framework suggests that neural systems for perception and action are engaged during higher cognitive processes. In an event-related fMRI study, we tested this claim for the abstract domain of numerical symbol processing: is the human cortical motor system part of the representation of numbers, and is organization of numerical knowledge influenced by individual finger counting habits? Developmental studies suggest a link between numerals and finger counting habits due to the acquisition of numerical skills through finger counting in childhood. In the present study, digits 1 to 9 and the corresponding number words were presented visually to adults with different finger counting habits, i.e. left- and right-starters who reported that they usually start counting small numbers with their left and right hand, respectively. Despite the absence of overt hand movements, the hemisphere contralateral to the hand used for counting small numbers was activated when small numbers were presented. The correspondence between finger counting habits and hemispheric motor activation is consistent with an intrinsic functional link between finger counting and number processing. PMID:22133748

The piecewise-linear dynamic attenuator reduces the impact of count rate loss with photon-counting detectors.  

PubMed

Photon counting x-ray detectors (PCXDs) offer several advantages compared to standard energy-integrating x-ray detectors, but also face significant challenges. One key challenge is the high count rates required in CT. At high count rates, PCXDs exhibit count rate loss and show reduced detective quantum efficiency in signal-rich (or high flux) measurements. In order to reduce count rate requirements, a dynamic beam-shaping filter can be used to redistribute flux incident on the patient. We study the piecewise-linear attenuator in conjunction with PCXDs without energy discrimination capabilities. We examined three detector models: the classic nonparalyzable and paralyzable detector models, and a 'hybrid' detector model which is a weighted average of the two which approximates an existing, real detector (Taguchi et al 2011 Med. Phys. 38 1089-102). We derive analytic expressions for the variance of the CT measurements for these detectors. These expressions are used with raw data estimated from DICOM image files of an abdomen and a thorax to estimate variance in reconstructed images for both the dynamic attenuator and a static beam-shaping ('bowtie') filter. By redistributing flux, the dynamic attenuator reduces dose by 40% without increasing peak variance for the ideal detector. For non-ideal PCXDs, the impact of count rate loss is also reduced. The nonparalyzable detector shows little impact from count rate loss, but with the paralyzable model, count rate loss leads to noise streaks that can be controlled with the dynamic attenuator. With the hybrid model, the characteristic count rates required before noise streaks dominate the reconstruction are reduced by a factor of 2 to 3. We conclude that the piecewise-linear attenuator can reduce the count rate requirements of the PCXD in addition to improving dose efficiency. The magnitude of this reduction depends on the detector, with paralyzable detectors showing much greater benefit than nonparalyzable detectors. PMID:24819415

Far-Ultraviolet Number Counts of Field Galaxies  

NASA Technical Reports Server (NTRS)

The Number counts of far-ultraviolet (FUV) galaxies as a function of magnitude provide a direct statistical measure of the density and evolution of star-forming galaxies. We report on the results of measurements of the rest-frame FUV number counts computed from data of several fields including the Hubble Ultra Deep Field, the Hubble Deep Field North, and the GOODS-North and -South fields. These data were obtained from the Hubble Space Telescope Solar Blind Channel of the Advance Camera for Surveys. The number counts cover an AB magnitude range from 20-29 magnitudes, covering a total area of 15.9 arcmin'. We show that the number counts are lower than those in previous studies using smaller areas. The differences in the counts are likely the result of cosmic variance; our new data cover more area and more lines of sight than the previous studies. The slope of our number counts connects well with local FUV counts and they show good agreement with recent semi-analytical models based on dark matter "merger trees".

Full counting statistics of a Luttinger liquid conductor.  

PubMed

Nonequilibrium bosonization technique is used to study current fluctuations of interacting electrons in a single-channel quantum wire representing a Luttinger liquid (LL) conductor. An exact expression for the time resolved full counting statistics of the transmitted charge is derived. It is given by the Fredholm determinant of the counting operator with a time-dependent scattering phase. The result has a form of counting statistics of noninteracting particles with fractional charges, induced by scattering off the boundaries between the LL wire and the noninteracting leads.

Thermostable cocktail for the liquid scintillation counting of heterogeneous media  

SciTech Connect

Considerable analytical errors arise in the liquid scintillation counting of heterogeneous media as a consequence of gel instability. With large sample numbers, a major causative factor of this instability is temperature changes during the counting period. An emulsifier-scintillation cocktail has been designed to provide stable counting conditions for heterogeneous media over a temperature range of 10-30/sup 0/C, i.e., the wide range of temperature likely to be encountered in liquid scintillation counters lacking sample cooling facilities. A comparison was made with a conventional commercially available emulsifier-scintillator.

An error accounting algorithm for electron counting experiments  

E-print Network

Electron counting experiments attempt to provide a current of a known number of electrons per unit time. We propose architectures utilizing a few readily available electron-pumps or turnstiles with modest error rates of 1 part per $10^4$ with common sensitive electrometers to achieve the desirable accuracy of 1 part in $10^8$. This is achieved not by counting all transferred electrons but by counting only the errors of individual devices; these are less frequent and therefore readily recognized and accounted for. Our proposal thereby eases the route towards quantum based standards for current and capacitance.

Automatic Pedestrian Detection and Counting Applied to Urban Planning  

NASA Astrophysics Data System (ADS)

The statistical knowledge of human flows in the streets is mandatory for urban planning. Today many cities use the expensive method of manual pedestrian counting, since there is no reliable automatic counting device. This project aims at achieving the first efficient, real-time, embedded and autonomous system that provides high-level data. Our first work focused on the development of a reliable counting method under MatlabTM. On the basis of video sequences recorded in the city of Mulhouse we have validated the robustness of our approach.

A tutorial on count regression and zero-altered count models for longitudinal substance use data.  

PubMed

Critical research questions in the study of addictive behaviors concern how these behaviors change over time: either as the result of intervention or in naturalistic settings. The combination of count outcomes that are often strongly skewed with many zeroes (e.g., days using, number of total drinks, number of drinking consequences) with repeated assessments (e.g., longitudinal follow-up after intervention or daily diary data) present challenges for data analyses. The current article provides a tutorial on methods for analyzing longitudinal substance use data, focusing on Poisson, zero-inflated, and hurdle mixed models, which are types of hierarchical or multilevel models. Two example datasets are used throughout, focusing on drinking-related consequences following an intervention and daily drinking over the past 30 days, respectively. Both datasets as well as R, SAS, Mplus, Stata, and SPSS code showing how to fit the models are available on a supplemental website. PMID:22905895

Microprocessor Implementation of a Time Variant Floating Mean Counting Algorithm  

SciTech Connect

Rate estimation of nuclear pulses emitted from nuclear detectors has been well documented in papers written as early as 1965 to as recently as 1990. It is well known that pulses emitted from a nuclear detector can vary with time and an accurate estimate of the count rate must be based on a sifficient number of pulse counts within a sample period as well as the recent history of pulse counts acquired in previous windows to accurately estimate the current rate. This paper will review the attributes of three popular counting methods and show the implementation of one of these methods, the floating mean algorithm on an embedded controller system. The software discussion will look at how to apply the chosen algorithm on two popular platforms: the Motorola 68HC11 and the Intel 805X series embedded controllers.

Correlated neutron counting for the 21st century  

SciTech Connect

Correlated neutron counting techniques, such as neutron coincidence and multiplicity counting, are widely employed at nuclear fuel cycle facilities for the accountancy of nuclear material such as plutonium. These techniques need to be improved and enhanced to meet the challenges of complex measurement items and future nuclear safeguards applications, for example; the non-destructive assay of spent nuclear fuel, high counting rate applications, small sample measurements, and Helium-3 replacement. At the same time simulation tools, used for the design of detection systems based on these techniques, are being developed in anticipation of future needs. This seminar will present the theory and current state of the practice of temporally correlated neutron counting. A range of future safeguards applications will then be presented in the context of research projects at Los Alamos National Laboratory.

Counts of low-Redshift SDSS quasar candidates  

SciTech Connect

We analyze the counts of low-redshift quasar candidates selected using nine-epoch SDSS imaging data. The co-added catalogs are more than 1 mag deeper than single-epoch SDSS data, and allow the selection of low-redshift quasar candidates using UV-excess and also variability techniques. The counts of selected candidates are robustly determined down to g = 21.5. This is about 2 magnitudes deeper than the position of a change in the slope of the counts reported by Boyle et al. (1990, 2000) for a sample selected by UV-excess, and questioned by Hawkins & Veron (1995), who utilized a variability-selected sample. Using SDSS data, we confirm a change in the slope of the counts for both UV-excess and variability selected samples, providing strong support for the Boyle et al. results.

Multianode cylindrical proportional counter for high count rates  

DOEpatents

A cylindrical, multiple-anode proportional counter is provided for counting of low-energy photons (< 60 keV) at count rates of greater than 10/sup 5/ counts/sec. A gas-filled proportional counter cylinder forming an outer cathode is provided with a central coaxially disposed inner cathode and a plurality of anode wires disposed in a cylindrical array in coaxial alignment with and between the inner and outer cathodes to form a virtual cylindrical anode coaxial with the inner and outer cathodes. The virtual cylindrical anode configuration improves the electron drift velocity by providing a more uniform field strength throughout the counter gas volume, thus decreasing the electron collection time following the detection of an ionizing event. This avoids pulse pile-up and coincidence losses at these high count rates. Conventional RC position encoding detection circuitry may be employed to extract the spatial information from the counter anodes.

Dose reduction potential with photon counting computed tomography  

NASA Astrophysics Data System (ADS)

Electronic noise becomes a major source of signal degradation in low-dose clinical computed tomography (CT). In current clinical scanners based on energy integrating x-ray detectors, electronic noise from the readout circuits adds a noise of constant variance, which is negligible at high counts but can be significant at low count levels. On the other hand, in a photon counting detector (PCD) with pulse height discrimination capability, electronic noise has little to no impact on the measured signal. PCDs are known for their abilities to provide useful spectral information. In this work, we investigate this dose reduction to improve low-dose single-energy CT. We perform low-dose single-energy CT simulations using both energy integrating and photon counting detectors, and compare results with both analytical and iterative reconstructions (IR). The results demonstrate the dose reduction potential of PCDs in conventional low-dose single-energy CT examinations, when spectral information is not required.

A new stratification of mourning dove call-count routes  

USGS Publications Warehouse

The mourning dove (Zenaidura macroura) call-count survey is a nationwide audio-census of breeding mourning doves. Recent analyses of the call-count routes have utilized a stratification based upon physiographic regions of the United States. An analysis of 5 years of call-count data, based upon stratification using potential natural vegetation, has demonstrated that this uew stratification results in strata with greater homogeneity than the physiographic strata, provides lower error variance, and hence generates greatet precision in the analysis without an increase in call-count routes. Error variance was reduced approximately 30 percent for the contiguous United States. This indicates that future analysis based upon the new stratification will result in an increased ability to detect significant year-to-year changes.

High-accuracy calibration of photon-counting detectors

We discuss a practical implementation of a photon-counting detector calibration using correlated photon pairs produced by parametric down-conversion. In this calibration scheme, the detection of a first photon triggers the measurement sequence aimed at detection of a second photon by a detector under test (DUT). We also describe measurements of radiant power with a photon-counting detector, which is important for

NASA Technical Reports Server (NTRS)

Sealed channel plate photomultipliers with multiple discrete anodes for use as photon counting detectors in the image plane of Fabry-Perot interferometers are described. The influence of design and construction on performance of completed devices is discussed. Effects on spatial resolution, lifetime, and counting efficiency are described. It is shown that devices can be optimized for particular applications. The results should be generally applicable to resistive anode and wedge and strip anode types of sealed detectors.

The Cherenkov counting efficiency varies strongly with color quenching, thus correction curves must be used to obtain correct results. The external 152Eu source of a Quantulus 1220TM liquid scintillation counting (LSC) system was used to obtain a quench indicative parameter based on spectra area ratio. A color quench correction curve for aqueous samples containing 90Sr\\/90Y was prepared. The main advantage

Quantity judgments and individuation: evidence that mass nouns count.  

PubMed

Three experiments explored the semantics of the mass-count distinction in young children and adults. In Experiments 1 and 2, the quantity judgments of participants provided evidence that some mass nouns refer to individuals, as such. Participants judged one large portion of stuff to be "more" than three tiny portions for substance-mass nouns (e.g. mustard, ketchup), but chose according to number for count nouns (e.g. shoes, candles) and object-mass nouns (e.g. furniture, jewelry). These results suggest that some mass nouns quantify over individuals, and that therefore reference to individuals does not distinguish count nouns from mass nouns. Thus, Experiments 1 and 2 failed to support the hypothesis that there exist one-to-one mappings between mass-count syntax and semantics for either adults or young children. In Experiment 3, it was found that for mass-count flexible terms (e.g. string, stone) participants based quantity judgments on number when the terms were used with count syntax, but on total amount of stuff when used with mass syntax. Apparently, the presence of discrete physical objects in a scene (e.g. stones) is not sufficient to permit quantity judgments based on number. It is proposed that object-mass nouns (e.g. furniture) can be used to refer to individuals due to lexically specified grammatical features that normally occur in count syntax. Also, we suggest that children learning language parse words that refer to individuals as count nouns unless given morpho-syntactic and referential evidence to the contrary, in which case object-mass nouns are acquired.

The count rate dependent gain change of a microchannel plate photomultiplier has been measured. Gain changes of 60% have been observed for count rates in excess of 2 x 10/sup 5/ s/sup -1/. The microchannel plate photomultiplier was used as a multiplying element of a scintillation detector system using NaI(Tl) as the scintillator. Data are compared to a simplified model of this form of photomultiplier.

Modified single photon counting modules for optimal timing performance  

NASA Astrophysics Data System (ADS)

A modification of a standard Perkin Elmer SPCM-AQR photon detector module that remarkably improves the photon timing performance is presented here. The modification consists of an additional timing circuit board, which is inserted in the module without modifying the original circuit board. The essential feature is a pulse pickup linear network, connected to the high-voltage terminal of the photodetector, which extracts a short pulse signal with fast rise, coincident with the rise of the avalanche current. The information about the photon arrival time is obtained by sensing the onset of the rise. At low counting rates (<105counts/s) time-correlated photon counting tests show that the instrumental resolution function (IRF) thus obtained has full width at half maximum (FWHM) narrower by about 40% with respect to the original module. At higher counting rate, up to few Mcounts/s, the advantage is even more remarkable: The timing circuit practically eliminates the drawbacks that plague the original module, namely, a progressive increase of the FWHM and a progressive shift of the peak position of the IRF with increasing counting rate. The modified SPCM-AQR module is therefore suitable also for applications requiring subnanosecond time resolution at high and/or variable counting rate, such as fluorescent decay measurements, fluorescent lifetime imaging, single molecule detection and spectroscopy, and optical radar techniques.

Submillimeter Number Counts From Statistical Analysis of BLAST Maps  

E-print Network

We describe the application of a statistical method to estimate submillimeter galaxy number counts from the confusion limited observations of the Balloon-borne Large Aperture Submillimeter Telescope (BLAST). Our method is based on a maximum likelihood fit to the pixel histogram, sometimes called 'P(D)', an approach which has been used before to probe faint counts, the difference being that here we advocate its use even for sources with relatively high signal-to-noise ratios. This method has an advantage over standard techniques of source extraction in providing an unbiased estimate of the counts from the bright end down to flux densities well below the confusion limit. We specifically analyse BLAST observations of a roughly 10 sq. deg map centered on the Great Observatories Origins Deep Survey South field. We provide estimates of number counts at the three BLAST wavelengths, 250, 350, and 500 microns, instead of counting sources in flux bins we estimate the counts at several flux density nodes connected with ...

High-speed optical switch fabrics with large port count.  

PubMed

We report a novel architecture that can be used to construct optical switch fabrics with very high port count and nanoseconds switching speed. It is well known that optical switch fabrics with very fast switching time and high port count are challenging to realize. Currently, one of the most promising solutions is based on a combination of wavelength-tunable lasers and the arrayed waveguide grating router (AWGR). To scale up the number of ports in such switches, a direct method is to use AWGRs with a high channel count. However, such AWGRs introduce very large crosstalk noise due to the close wavelength channel spacing. In this paper, we propose an architecture for realizing a high-port count optical switch fabric using a combination of low-port count AWGRs, optical ON-OFF gates and WDM couplers. Using this new methodology, we constructed a proof-of concept experiment to demonstrate the feasibility of a 256 x 256 optical switch fabric. To our knowledge, this port count is the highest ever reported for switch fabrics of this type. PMID:19550498

Avalanche photodiode photon counting receivers for space-borne lidars  

NASA Technical Reports Server (NTRS)

Avalanche photodiodes (APD) are studied for uses as photon counting detectors in spaceborne lidars. Non-breakdown APD photon counters, in which the APD's are biased below the breakdown point, are shown to outperform: (1) conventional APD photon counters biased above the breakdown point; (2) conventional APD photon counters biased above the breakdown point; and (3) APD's in analog mode when the received optical signal is extremely weak. Non-breakdown APD photon counters were shown experimentally to achieve an effective photon counting quantum efficiency of 5.0 percent at lambda = 820 nm with a dead time of 15 ns and a dark count rate of 7000/s which agreed with the theoretically predicted values. The interarrival times of the counts followed an exponential distribution and the counting statistics appeared to follow a Poisson distribution with no after pulsing. It is predicted that the effective photon counting quantum efficiency can be improved to 18.7 percent at lambda = 820 nm and 1.46 percent at lambda = 1060 nm with a dead time of a few nanoseconds by using more advanced commercially available electronic components.

Evaluation of plasma eosinophil count and mean platelet volume in patients with coronary slow flow  

PubMed Central

OBJECTIVE: The pathophysiology of coronary slow flow has not been clearly defined, although multiple abnormalities including arteritis, endothelial dysfunction, and atherothrombosis, have been reported. It is known that eosinophils play an important role in inflammation, endothelial dysfunction, and thrombosis. We aimed to compare the eosinophil counts of coronary slow flow patients versus healthy controls. METHODS: This study included 50 coronary slow flow patients (19 males, mean age 65.6±13.7 years) and 30 healthy controls (10 males, mean age 57.86±11.6 years). These participants were evaluated using concurrent routine biochemical tests as well as neutrophil, lymphocyte, and eosinophil counts and mean platelet volume (MPV), which were obtained from the whole blood count. These parameters were compared between groups. RESULTS: The baseline characteristics of the study groups were comparable. The coronary slow flow patients had a higher mean platelet volume and eosinophil count than the control group (8.38±0.86 vs 6.28±1.6 fL and 0.31±0.42 vs 0.09±0.05; p<0.001 and 0.008, respectively). CONCLUSION: Our study demonstrated a relationship between eosinophil count and MPV in patients with coronary slow flow. PMID:24838897

Interaural Comparison of Spiral Ganglion Cell Counts in Profound Deafness  

PubMed Central

Objectives This study is designed to measure the degree to which spiral ganglion cell (SGC) survival in the left and right ears is similar in profoundly hearing-impaired human patients with symmetric (right/left) etiology and sensitivity. This is of interest because a small difference between ears would imply that one ear could be used as a control ear in temporal bone studies evaluating the impact on SGC survival of a medical intervention in the other ear. Materials and Methods Forty-two temporal bones from 21 individuals with bilaterally symmetric profound hearing impairment were studied. Both ears in each individual were impaired by the same etiology. Rosenthal’s canal was reconstructed in two dimensions and segmental and total SGCs were counted. Correlation analysis and t-tests were used to compare segmental and total counts of left and right ears. Statistical power calculations illustrate how the results can be used to estimate the effect size (right/left difference in SGC count) that can be reliably identified as a function of sample size. Results Left counts (segmental and total) were significantly correlated with those in the right ears (p<0.01) and the coefficients of determination for segments 1 to 4 and total count were respectively 0.64, 0.91, 0.93, 0.91 and 0.98. The hypothesis that mean segmental and total counts of right and left are the same could not be rejected by paired t-test. Conclusion The variance in the between-ear difference across the temporal bones studied indicates that useful effect sizes can be reliably identified using subject numbers that are practical for temporal bone studies. For instance, there is 95% likelihood that an interaural difference in SGC count of approximately 1000 cells associated with a treatment/manipulation of one ear will be reliably detected in a bilaterally-symmetric profound hearing loss population of temporal bones from approximately 10 subjects.

Biomolecular network motif counting and discovery by color coding  

PubMed Central

Protein–protein interaction (PPI) networks of many organisms share global topological features such as degree distribution, k-hop reachability, betweenness and closeness. Yet, some of these networks can differ significantly from the others in terms of local structures: e.g. the number of specific network motifs can vary significantly among PPI networks. Counting the number of network motifs provides a major challenge to compare biomolecular networks. Recently developed algorithms have been able to count the number of induced occurrences of subgraphs with k? 7 vertices. Yet no practical algorithm exists for counting non-induced occurrences, or counting subgraphs with k? 8 vertices. Counting non-induced occurrences of network motifs is not only challenging but also quite desirable as available PPI networks include several false interactions and miss many others. In this article, we show how to apply the ‘color coding’ technique for counting non-induced occurrences of subgraph topologies in the form of trees and bounded treewidth subgraphs. Our algorithm can count all occurrences of motif G? with k vertices in a network G with n vertices in time polynomial with n, provided k=O(log n). We use our algorithm to obtain ‘treelet’ distributions for k? 10 of available PPI networks of unicellular organisms (Saccharomyces cerevisiae Escherichia coli and Helicobacter Pyloris), which are all quite similar, and a multicellular organism (Caenorhabditis elegans) which is significantly different. Furthermore, the treelet distribution of the unicellular organisms are similar to that obtained by the ‘duplication model’ but are quite different from that of the ‘preferential attachment model’. The treelet distribution is robust w.r.t. sparsification with bait/edge coverage of 70% but differences can be observed when bait/edge coverage drops to 50%. Contact: cenk@cs.sfu.ca PMID:18586721

We provide estimates of number counts at the three BLAST wavelengths 250, 350, and 500 mum; instead of counting sources in flux bins we estimate the counts at several flux density nodes connected with power laws. We observe a generally very steep slope for the counts of about -3.7 at 250 mum, and -4.5 at 350 and 500 mum, over the range approx0.02-0.5 Jy, breaking to a shallower slope below about 0.015 Jy at all three wavelengths. We also describe how to estimate the uncertainties and correlations in this method so that the results can be used for model-fitting. This method should be well suited for analysis of data from the Herschel satellite.

A system for counting fetal and maternal red blood cells.  

PubMed

The Kleihauer-Betke (KB) test is the standard method for quantitating fetal-maternal hemorrhage in maternal care. In hospitals, the KB test is performed by a certified technologist to count a minimum of 2000 fetal and maternal red blood cells (RBCs) on a blood smear. Manual counting suffers from inherent inconsistency and unreliability. This paper describes a system for automated counting and distinguishing fetal and maternal RBCs on clinical KB slides. A custom-adapted hardware platform is used for KB slide scanning and image capturing. Spatial-color pixel classification with spectral clustering is proposed to separate overlapping cells. Optimal clustering number and total cell number are obtained through maximizing cluster validity index. To accurately identify fetal RBCs from maternal RBCs, multiple features including cell size, roundness, gradient, and saturation difference between cell and whole slide are used in supervised learning to generate feature vectors, to tackle cell color, shape, and contrast variations across clinical KB slides. The results show that the automated system is capable of completing the counting of over 60 000 cells (versus  ? 2000 by technologists) within 5 min (versus  ? 15 min by technologists). The throughput is improved by approximately 90 times compared to manual reading by technologists. The counting results are highly accurate and correlate strongly with those from benchmarking flow cytometry measurement. PMID:24879644

Association of TNFSF8 Polymorphisms With Peripheral Neutrophil Count  

PubMed Central

OBJECTIVE: To investigate the association between 347 single-nucleotide polymorphisms within candidate genes of the tumor necrosis factor, interleukin 1 and interleukin 6 families with neutrophil count. PATIENTS AND METHODS: Four hundred cases with heart failure after myocardial infarction (MI) were matched by age, sex, and date of incident MI to 694 controls (MI without post-MI heart failure). Both genotypes and neutrophil count at admission for incident MI were available in 314 cases and 515 controls. RESULTS: We found significant associations between the TNFSF8 poly morphisms rs927374 (P=5.1 x 10–5) and rs2295800 (P=1.3 x 10–4) and neutrophil count; these single-nucleotide polymorphisms are in high linkage disequilibrium (r2=0.97). Associations persisted after controlling for clinical characteristics and were unchanged after adjusting for case-control status. For rs927374, the neutrophil count of GG homozygotes (7.6±5.1) was 16% lower than that of CC homozygotes (9.0±5.2). CONCLUSION: The TNFSF8 polymorphisms rs927374 and rs2295800 were associated with neutrophil count. This finding suggests that post-MI inflammatory response is genetically modulated. PMID:22033252

Correction for nonlinear photon counting effects in lidar systems  

NASA Technical Reports Server (NTRS)

Photomultiplier tubes (PMT's) employed in the photon counting (PC) mode of operation are widely used as detectors in lidar systems. In our laboratory, we have developed a versatile Nd:YAG lidar which is used for measurement of both the middle atmosphere and the troposphere. With this system, we encounter a very wide range of signal levels ranging from the extremely weak signals from the top of the mesosphere to the very strong returns from low level clouds. Although the system is capable of operating the PMT's in either the analog detection or photon counting mode, we find that often when we use photon counting we have portions of our lidar return which contain very useful information but are not within the linear operating regime of the PC system. We report the results of our efforts to explore the extent to which such high intensity PC signals can be quantitatively analyzed. In particular, a useful model relating the mean 'true' count rate and the observed count rate is presented and it's application to our system demonstrated. This model takes into account the variation in height of the PMT output pulses and the effect of the pulse height discrimination threshold.

Development of a stained cell nuclei counting system  

NASA Astrophysics Data System (ADS)

This paper presents a novel cell counting system which exploits the Fast Radial Symmetry Transformation (FRST) algorithm [1]. The driving force behind our system is a research on neurogenesis in the intact nervous system of Manduca Sexta or the Tobacco Hornworm, which was being studied to assess the impact of age, food and environment on neurogenesis. The varying thickness of the intact nervous system in this species often yields images with inhomogeneous background and inconsistencies such as varying illumination, variable contrast, and irregular cell size. For automated counting, such inhomogeneity and inconsistencies must be addressed, which no existing work has done successfully. Thus, our goal is to devise a new cell counting algorithm for the images with non-uniform background. Our solution adapts FRST: a computer vision algorithm which is designed to detect points of interest on circular regions such as human eyes. This algorithm enhances the occurrences of the stained-cell nuclei in 2D digital images and negates the problems caused by their inhomogeneity. Besides FRST, our algorithm employs standard image processing methods, such as mathematical morphology and connected component analysis. We have evaluated the developed cell counting system with fourteen digital images of Tobacco Hornworm's nervous system collected for this study with ground-truth cell counts by biology experts. Experimental results show that our system has a minimum error of 1.41% and mean error of 16.68% which is at least forty-four percent better than the algorithm without FRST.

Compensated count-rate circuit for radiation survey meter  

DOEpatents

A count-rate compensating circuit is provided which may be used in a portable Geiger-Mueller (G-M) survey meter to ideally compensate for counting loss errors in the G-M tube detector. In a G-M survey meter, wherein the pulse rate from the G-M tube is converted into a pulse rate current applied to a current meter calibrated to indicate dose rate, the compensated circuit generates and controls a reference voltage in response to the rate of pulses from the detector. This reference voltage is gated to the current-generating circuit at a rate identical to the rate of pulses coming from the detector so that the current flowing through the meter is varied in accordance with both the frequency and amplitude of the reference voltage pulses applied thereto so that the count rate is compensated ideally to indicate a true count rate within 1% up to a 50% duty cycle for the detector. A positive feedback circuit is used to control the reference voltage so that the meter output tracks true count rate indicative of the radiation dose rate.

Total pollen counts do not influence active surface measurements  

NASA Astrophysics Data System (ADS)

We investigated the temporal association of various aerosol parameters with pollen counts in the pollen season (April 2001) in Linz, Austria. We were especially interested in the relationship between active surface (or Fuchs' surface) because we had shown previously (Atmos. Environ. 37 (2003) 1737-1744) that this parameter during the same observation period was a better predictor for acute respiratory symptoms in school children (like wheezing, shortness of breath, and cough) and reduced lung function on the same day than particle mass (PM 10). While active surface is most sensitive for fine particles with a diameter of less than 100 nm it has no strict upper cut-off regarding particle size and so could eventually be influenced also by larger particles if their numbers were high. All particle mass parameters tested (TSP, PM 10, PM 1) were weakly ( r approximately 0.2) though significantly correlated with pollen counts but neither was active surface nor total particle counts (CPC). The weak association of particle mass and pollen counts was due mainly to similar diurnal variations and a linear trend over time. Only the mass of the coarse fraction (TSP minus PM 10) remained associated with pollen counts significantly after controlling for these general temporal patterns.

Photon counting spectroscopy as done with a Thomson scattering diagnostic  

SciTech Connect

The measurement and reduction of photon counting spectral data is demonstrated within the context of a Thomson scattering diagnostic. This diagnostic contains a microchannel plate (MCP) photomultiplier tube (PMT) as the photon sensing device. The MCP PMT is not an ideal photon sensor, the loss of photoelectrons at the MCP input and the broad charge pulse distribution at the output add to the uncertainty in recorded data. Computer simulations are used to demonstrate an approach to quantification of this added uncertainty and to develop an understanding of its source; the methodology may be applicable to the development of an understanding of photon detectors other than an MCP PMT. Emphasis is placed on the Poisson statistical character of the data, because the assumption that a Gaussian probability distribution is a reasonable statistical description of photon counting data is often questionable. When the count rate is low, the product the possible number of photon counts and the probability of measurement of a single photon is usually not sufficiently large to justify Gaussian statistics. Rather, because probabilities of measurement are so low, the Poisson probability distribution best quantifies the inherent statistical fluctuations in such counting measurements. The method of maximum likelihood is applied to derive the Poisson statistics equivalent of {sub X}{sup 2}. A Poisson statistics based data fitting code is implemented using the Newton-Raphson method of multi-dimensional root finding; we also demonstrate an algorithm to estimate the uncertainties in derived quantities.

Counting radioactive noble gas atoms: Lasers, accelerators or decay counters?  

NASA Astrophysics Data System (ADS)

Radon-220 and Radon-222 in environmental air samples can be measured on-line with high temporal resolution by state-of-the-art alpha counting. Argon-37, Krypton-85 and Argon-39 are measured routinely by low level decay counting using high-pressure gas proportional counters in an underground laboratory. For Krypton-81 decay counting is not possible in environmental samples. Therefore, various attempts have been made to use atom counting techniques for this isotope. Laser Resonance Ionization Spectroscopy was used to count Kr-81 atoms from old groundwater samples. In a more recent study groundwater dating in the Great Artesian Basin in Australia was accomplished using Cyclotron Accelerator Mass Spectroscopy. Collinear Beam Spectroscopy using Photon Burst Detection and Atom Trap Trace Analysis were successfully used to detect both Kr-81 and Kr-85 in natural Kr samples. Most of these new techniques, however, need to be further improved to become routine tools in environmental studies. 2001 American Institute of Physics.

Pediatric metabolic syndrome and cell blood counts: bivariate Bayesian modeling.  

PubMed

Cell blood counts are components of hematological parameters and indicators of pro-inflammatory states. They are proposed to be associated with metabolic syndrome (MetS). This study aimed to assess the relationship of the white blood cell (WBC) and the red blood cell (RBC) counts with components of MetS in the pediatric age group. The sample consisted of 300 children (152 boys) aged 6-12 years. Hierarchical Bayesian analysis of the bivariate Poisson regression model was used to estimate the effect of various components of MetS according to the cell blood counts. We found that RBC and WBC counts were correlated with the fasting blood glucose, the waist-to-height ratio, serum triglycerides and the blood pressure levels adjusted for age, the body mass index, gender, total cholesterol, low-density lipoprotein cholesterol and the hip circumference. The high-density lipoprotein cholesterol was correlated with the RBC counts based on 95% high posterior density regions for parameters in the Bayesian model. Our findings may serve as confirmatory evidence for the beginning of inflammatory process related to the cardio-metabolic factors from early life. PMID:24108065

An electronic pollen detection method using Coulter counting principle  

NASA Astrophysics Data System (ADS)

A method for detecting and counting pollen particles based on Coulter counting principle is presented. This approach also provides information on the size and surface charges of the micro particles, allowing for preliminary differentiation of pollens from other micro particles. Three samples are studied: polymethyl methacrylate particles, tree pollens from Juniperus Scopulorum and grass pollens from Secale Cerale. The samples, suspended in diluted KCl aqueous solutions in an electrochemical cell, were allowed to pass through a microchannel and the conductance of the microchannel was sampled with a Gamry ® Potentiostat. The changes in the conductance due to the passing of the micro particles was thus recorded and analyzed. The experimental results showed that tree pollens and grass pollens display distinctive behaviors. The phenomena may be attributed to the differences in the surface characteristics of the pollens and is potentially useful for counting and differentiating different micro particles.

Models for predicting and explaining citation count of biomedical articles.  

PubMed

The single most important bibliometric criterion for judging the impact of biomedical papers and their authors work is the number of citations received which is commonly referred to as citation count. This metric however is unavailable until several years after publication time. In the present work, we build computer models that accurately predict citation counts of biomedical publications within a deep horizon of ten years using only predictive information available at publication time. Our experiments show that it is indeed feasible to accurately predict future citation counts with a mixture of content-based and bibliometric features using machine learning methods. The models pave the way for practical prediction of the long-term impact of publication, and their statistical analysis provides greater insight into citation behavior. PMID:18999029

Dynamics and regulation of bulk milk somatic cell counts.  

PubMed Central

Somatic cell count (SCC) in milk is inversely related to dairy cow productivity and milk quality. In an effort to improve product quality, and indirectly farm productivity, regulatory limits on somatic cell counts have been established by many of the major dairy producing countries. The purpose of this paper was to assess the impact of regulations on bulk milk somatic cell counts in Ontario and to assist producers in meeting regulatory limits through development of prediction models. Through the use of a transfer function model, provincial SCC was found to have dropped by approximately 60,000 as a result of the reduction program. Limits of the regulatory program, seasonality and herd characteristics were found through time series cross-sectional models to have an impact on prediction of SCC at the farm level, but the major influence was historical SCC levels.

Accuracy enhancement of fatigue damage counting using design sensitivity analysis  

NASA Astrophysics Data System (ADS)

Recent studies have suggested fatigue damage counting of a linear elastic system using only the output data; design sensitivity analysis based on the transmissibility function was studied in order to identify the most sensitive response location under intact conditions. The design sensitivity index was derived to be proportional to the response energy at the measured point through reformulation of the previous equation for the sensitivity index. The accuracy of the damage counting method can be enhanced with design sensitivity analysis by selecting the location with the maximum response energy; the method is optimally robust against unexpected noise in the output data. Simulation and testing of a notched simple specimen under uniaxial excitation were used to verify that sensitivity analysis enhances the accuracy of the predicted damage counting.

Yield of the admission complete blood count in medical inpatients.  

PubMed Central

The clinical efficacy of routine admission complete blood count was evaluated in 302 patients admitted to internal medicine wards of a university teaching hospital. Patient medical problems, physical findings and medication history were evaluated by preset criteria to determine the proportion of tests performed for screening and the proportion of test results directly influencing patient management. Of the 282 complete blood counts performed, 80% were ordered routinely with no medical indications (screening tests). An haemoglobin abnormality was found in 16.7% of the patients, leucocyte abnormality in 16.1% and platelet abnormality in 4.6%. However, these results directly influenced patient management in only one case (0.14%). It is concluded that the utility of screening admission complete blood counts in medical inpatients is negligible. PMID:2602251

Effect of measurement duration on accuracy of pulse-counting.  

PubMed

In this study, the relation between the measurement duration and accuracy of pulse-counting was quantitatively examined with special reference to low-frequency fluctuations in heart rate variability. The interbeat intervals of 70 healthy male subjects were measured in standing, sitting and supine positions. Pulse rates for various durations were calculated by objective-scoring simulation based on the heartbeat recordings of the subjects. The duration of pulse-counting continuously varied from 6 to 60 s in the simulation. Simulated pulse rates were compared with the rate calculated from the 60 s that includes the given duration, and the absolute difference between the two rates was defined as the error. Average errors of pulse-counting for 15 s were 1.89, 1.89 and 1.80 bpm for standing, sitting and supine positions, respectively. No difference in error was observed between standing and sitting positions; however, smaller errors were observed in the supine position. PMID:24117167

Rainflow counting algorithm for the LIFE2 fatigue analysis code  

NASA Astrophysics Data System (ADS)

The LIFE2 computer code is a fatigue/fracture analysis code that is specialized to the analysis of wind turbine components. The numerical formulation of the code uses a series of cycle count matrices to describe the cyclic stress states imposed upon the turbine. In this formulation, each stress cycle is counted or binsed according to the magnitude of its mean stress and alternating stress components and by the operating condition of the turbine. A set of numerical algorithms are described that were incorporated into the LIFE2 code. These algorithms determine the cycle count matrices for a turbine component using stress-time histories of the imposed stress states. Example problems are used to illustrate the use of these algorithms.

On the power counting in effective field theories  

NASA Astrophysics Data System (ADS)

We discuss the systematics of power counting in general effective field theories, focusing on those that are nonrenormalizable at leading order. As an illuminating example we consider chiral perturbation theory gauged under the electromagnetic U(1) symmetry. This theory describes the low-energy interactions of the octet of pseudo-Goldstone bosons in QCD with photons and has been discussed extensively in the literature. Peculiarities of the standard approach are pointed out and it is shown how these are resolved within our scheme. The presentation follows closely our recent discussion of power counting for the electroweak chiral Lagrangian. The systematics of the latter is reviewed and shown to be consistent with the concept of chiral dimensions. The results imply that naive dimensional analysis (NDA) is incomplete in general effective field theories, while still reproducing the correct counting in special cases.

Gasolines as primary solvents in liquid scintillation counting  

SciTech Connect

Gasolines from several commercial sources have been used as primary solvents in liquid scintillation counting of dry and aqueous samples of either /sup 3/H- or /sup 14/C-labeled compounds. Dry samples can be counted only by the addition of fluors to the gasolines, and compared to a standard liquid scintillator, efficiencies of around 75% were attained. For the counting of aqueous samples, gasolines must also be supplemented with secondary solvents (i.e., 10% naphthalene, 5% Triton X-100, or 10% methanol). Simply with Triton X-100, efficiencies similar to those obtained with a dioxane-based liquid scintillator were observed in the case of some gasolines. Drawbacks to gasoline are the higher toxicity and the variation of efficiency, probably depending on the presence of color markers. On the positive side is the low price of the gasolines, compared with either toluene or dioxane, and the facility of purchasing.

A new model for time series of counts  

NASA Astrophysics Data System (ADS)

Time series modelling is an active research area in the past few decades with much attention focused in the continuous setting. However, time series data in terms of correlated counts occur in many situations. Thus modelling of time series of count data has attracted the attention many researchers recently. A new univariate non-negative stationary time series model of count data is introduced and is referred to as the mixture of Pegram and thinning on first order integer-valued autoregressive (MPT(1)) process. It is constructed from the combination of the popular thinning and Pegram's operators. The motivation for introducing the model and important statistical properties are discussed, such as autocorrelation, regression and joint distribution. Some simulation results are presented to show the performance of the model. Finally, the advantage of this new model is illustrated with application to a real data set.

Cell Counting in Human Endobronchial Biopsies - Disagreement of 2D versus 3D Morphometry  

PubMed Central

Question Inflammatory cell numbers are important endpoints in clinical studies relying on endobronchial biopsies. Assumption-based bidimensional (2D) counting methods are widely used, although theoretically design-based stereologic three-dimensional (3D) methods alone offer an unbiased quantitative tool. We assessed the method agreement between 2D and 3D counting designs in practice when applied to identical samples in parallel. Materials and Methods Biopsies from segmental bronchi were collected from healthy non-smokers (n?=?7) and smokers (n?=?7), embedded and sectioned exhaustively. Systematic uniform random samples were immunohistochemically stained for macrophages (CD68) and T-lymphocytes (CD3), respectively. In identical fields of view, cell numbers per volume unit (NV) were assessed using the physical disector (3D), and profiles per area unit (NA) were counted (2D). For CD68+ cells, profiles with and without nucleus were separately recorded. In order to enable a direct comparison of the two methods, the zero-dimensional CD68+/CD3+-ratio was calculated for each approach. Method agreement was tested by Bland-Altmann analysis. Results In both groups, mean CD68+/CD3+ ratios for NV and NA were significantly different (non-smokers: 0.39 and 0.68, p<0.05; smokers: 0.49 and 1.68, p<0.05). When counting only nucleated CD68+ profiles, mean ratios obtained by 2D and 3D counting were similar, but the regression-based Bland-Altmann analysis indicated a bias of the 2D ratios proportional to their magnitude. This magnitude dependent deviation differed between the two groups. Conclusions 2D counts of cell and nuclear profiles introduce a variable size-dependent bias throughout the measurement range. Because the deviation between the 3D and 2D data was different in the two groups, it precludes establishing a ‘universal conversion formula’. PMID:24663339

An analysis of dependency of counting efficiency on worker anatomy for in vivo measurements: whole-body counting  

NASA Astrophysics Data System (ADS)

In vivo radiobioassay is integral to many health physics and radiological protection programs dealing with internal exposures. The Bottle Manikin Absorber (BOMAB) physical phantom has been widely used for whole-body counting calibrations. However, the shape of BOMAB phantoms—a collection of plastic, cylindrical shells which contain no bones or internal organs—does not represent realistic human anatomy. Furthermore, workers who come in contact with radioactive materials have rather different body shape and size. To date, there is a lack of understanding about how the counting efficiency would change when the calibrated counter is applied to a worker with complicated internal organs or tissues. This paper presents a study on various in vivo counting efficiencies obtained from Monte Carlo simulations of two BOMAB phantoms and three tomographic image-based models (VIP-Man, NORMAN and CNMAN) for a scenario involving homogeneous whole-body radioactivity contamination. The results reveal that a phantom's counting efficiency is strongly dependent on the shape and size of a phantom. Contrary to what was expected, it was found that only small differences in efficiency were observed when the density and material composition of all internal organs and tissues of the tomographic phantoms were changed to water. The results of this study indicate that BOMAB phantoms with appropriately adjusted size and shape can be sufficient for whole-body counting calibrations when the internal contamination is homogeneous.

Estimation of atomic interaction parameters by photon counting  

NASA Astrophysics Data System (ADS)

Detection of radiation signals is at the heart of precision metrology and sensing. In this article we show how the fluctuations in photon-counting signals can be exploited to optimally extract information about the physical parameters that govern the dynamics of the emitter. For a simple two-level emitter subject to photon counting, we show that the Fisher information and the Cramér-Rao sensitivity bound based on the full detection record can be evaluated from the waiting-time distribution in the fluorescence signal which can, in turn, be calculated for both perfect and imperfect detectors by a quantum trajectory analysis. We provide an optimal estimator achieving that bound.

Universal count correction for high-throughput sequencing.  

PubMed

We show that existing RNA-seq, DNase-seq, and ChIP-seq data exhibit overdispersed per-base read count distributions that are not matched to existing computational method assumptions. To compensate for this overdispersion we introduce a nonparametric and universal method for processing per-base sequencing read count data called FIXSEQ. We demonstrate that FIXSEQ substantially improves the performance of existing RNA-seq, DNase-seq, and ChIP-seq analysis tools when compared with existing alternatives. PMID:24603409

Applying these measurements in a Hanbury Brown and Twiss set-up, phonon correlations of the nanomechanical resonator are explored from below to above threshold of a parametric instability leading to self-oscillation of the resonator. Discussion of the results in terms of a "phonon laser", and analysis of the sensitivity of the phonon counting technique are presented.

The Early Years: Counting a Culture of Mealworms  

NSDL National Science Digital Library

Math is not the only topic that will be discussed when young children are asked to care for and count "mealworms," a type of insect larvae (just as caterpillars are the babies of butterflies, these larvae are babies of beetles). The following activity can take place over two months as the beetles undergo metamorphosis from larvae to adults. As the children care for and count the insects, they will make observations, think what defines an insect, begin to understand life cycles and life spans, and gain big vocabulary words that they love to know and use to feel like "real" scientists.

Spermatid count as a predictor of response to FSH therapy.

This study evaluated the predictive power of spermatid count and cytology for assisted reproduction outcome after FSH therapy. A total of 174 men with severe oligozoospermia and normal plasma FSH concentration underwent semen analysis including spermatid count, TUNEL test, FISH analysis for sperm aneuploidies and testicular fine-needle aspiration cytology. Ninety-two men with hypospermatogenesis received FSH therapy for 3 months and 82 patients with maturative disturbance or partial obstruction served as controls. Semen was analysed at baseline, after FSH therapy and after 3- and 9-month follow up, and pregnancies were recorded. Subjects not reaching pregnancy at 3-month follow up were recommended assisted reproduction treatment. Spermatid count was related to testicular cytology: spermatid concentrations <0.01, 0.01-0.3 and >0.3 × 10(6)/ml were predictive of partial obstruction, hypospermatogenesis and maturative disturbance. FSH therapy patients showed increases in sperm number and motility (both P < 0.001), allowing some couples to undergo intrauterine insemination instead of IVF. Cumulative pregnancy rate after 12 months was higher with FSH therapy (44.6%) than without (22.0%; P = 0.002). FSH therapy improved pregnancy rate and sometimes allowed less invasive assisted reproduction treatment in well-selected patients. Spermatid count could represent a new parameter to predict response to FSH therapy. One-hundred seventy-four patients with severe reduction of sperm count and normal sex hormones plasma levels underwent semen analysis with spermatid count, and testicular fine needle aspiration cytologiy (FNAC). Ninety-two men infertile men with reduced sperm production (hypospermatogenesis) were treated with highly purified urofollitropin and 82 patients with sperm maturative defects or partial obstruction of the seminal tract served as controls. After treatment and after the following 3 and 9 months all subjects performed a new semen analysis and pregnancies were recorded. Subjects who had not reached spontaneous pregnancy were suggested to undergo assisted reproductive techniques (ARTs). Spermatid count was strongly related to testicular cytology: spermatid concentrations were predictive of partial obstruction, hypospermatogenesis and maturative disturbance respectively. Treated patients showed significant increase in sperm number and motility allowing some couples to undergo easier and less invasive assisted reproductive techniques. The number of pregnancies was significantly higher among treated (44.6%) than untreated couples (22.0%). Our data confirmed that FSH treatment can induce a significant improvemet of pergnancy rate and sometimes allows less invasive ARTs use in well selected severe oligozoospermic patients. Moreover, we suggest that spermatid count can be useful to define tubular status and could represent a new parameter to predict response to FSH therapy. PMID:24816256

Single-electron counting statistics with a finite frequency bandwidth  

NASA Astrophysics Data System (ADS)

Single-electron counting is widely used to probe single electron dynamics and correlated electron transport through quantum dots. However, finite frequency bandwidth in amplifying and analyzing the detector current removes fast counting events and alters the statistics. We have developed a correction scheme to obtain the actual tunneling rates through a quantum dot, when the detector has a low pass filter with a cutoff frequency comparable to the rates. The accuracy of our scheme is confirmed by simulating the filtering effect on Poisson random switching events and by applying it to experimental data for self-checking.

Comparison of Limulus assay, standard plate count, and total coliform count for microbiological assessment of renovated wastewater.  

PubMed Central

The Limulus endotoxin assay was compared to the standard plate count and total coliform count for assessment of the bacteriological quality of reclaimed wastewater. A total of 48 water samples from an advanced waste treatment plant in Dallas, Tex. were examined by the three techniques. Limulus assays were technically simpler to perform and provided results much sooner than conventional culture methods. However, the endotoxin values did not correlate extremely well with determinations of viable bacterial numbers. This lack of correlation may have been due to alterations in the normal ratio of viable gram-negative cells to endotoxin caused by water reclamation procedures. PMID:384901

Estimating departure times from traffic counts using dynamic assignment  

SciTech Connect

A dynamic traffic assignment algorithm and observed traffic counts are used to estimate the distribution of departure times in a trip matrix. The objective is to find the maximum entropy distribution of departure times by origin zone subject to observed traffic counts on a subset of network links. The procedure results in the estimated number of trip departures from each origin in 10-15 minute time intervals of the full analysis period. Such an analysis period will typically range from one to three hours long. We first review the dynamic assignment algorithm developed and tested in a previous paper, and then describe its use with traffic counts to estimate the departure times of a trip matrix. We present an application to a Pittsburgh network in which trip departures are estimated for each 10-minute interval of a peak-hour survey trip matrix. Computational advances such as parallel computing will enable the procedure to be run on large networks while counts are being monitored. Such an application may provide near real-time detection of temporal trip departure profiles by origin zone. 19 refs., 1 fig., 2 tabs.

Compensated count-rate circuit for radiation survey meter  

DOEpatents

A count-rate compensating circuit is provided which may be used in a portable Geiger-Mueller (G-M) survey meter to ideally compensate for couting loss errors in the G-M tube detector. In a G-M survey meter, wherein the pulse rate from the G-M tube is converted into a pulse rate current applied to a current meter calibrated to indicate dose rate, the compensation circuit generates and controls a reference voltage in response to the rate of pulses from the detector. This reference voltage is gated to the current-generating circuit at a rate identical to the rate of pulses coming from the detector so that the current flowing through the meter is varied in accordance with both the frequency and amplitude of the reference voltage pulses applied thereto so that the count rate is compensated ideally to indicate a true count rate within 1% up to a 50% duty cycle for the detector. A positive feedback circuit is used to control the reference voltage so that the meter output tracks true count rate indicative of the radiation dose rate.

Generalized estimators of avian abundance from count survey data  

USGS Publications Warehouse

I consider modeling avian abundance from spatially referenced bird count data collected according to common protocols such as capture?recapture, multiple observer, removal sampling and simple point counts. Small sample sizes and large numbers of parameters have motivated many analyses that disregard the spatial indexing of the data, and thus do not provide an adequate treatment of spatial structure. I describe a general framework for modeling spatially replicated data that regards local abundance as a random process, motivated by the view that the set of spatially referenced local populations (at the sample locations) constitute a metapopulation. Under this view, attention can be focused on developing a model for the variation in local abundance independent of the sampling protocol being considered. The metapopulation model structure, when combined with the data generating model, define a simple hierarchical model that can be analyzed using conventional methods. The proposed modeling framework is completely general in the sense that broad classes of metapopulation models may be considered, site level covariates on detection and abundance may be considered, and estimates of abundance and related quantities may be obtained for sample locations, groups of locations, unsampled locations. Two brief examples are given, the first involving simple point counts, and the second based on temporary removal counts. Extension of these models to open systems is briefly discussed.

Absolute counting of neutrophils in whole blood using flow cytometry.  

PubMed

Absolute neutrophil count (ANC) is used clinically to monitor physiological dysfunctions such as myelosuppression or infection. In the research laboratory, ANC is a valuable measure to monitor the evolution of a wide range of disease states in disease models. Flow cytometry (FCM) is a fast, widely used approach to confidently identify thousands of cells within minutes. FCM can be optimised for absolute counting using spiked-in beads or by measuring the sample volume analysed. Here we combine the 1A8 antibody, specific for the mouse granulocyte protein Ly6G, with flow cytometric counting in straightforward FCM assays for mouse ANC, easily implementable in the research laboratory. Volumetric and Trucount™ bead assays were optimized for mouse neutrophils, and ANC values obtained with these protocols were compared to ANC measured by a dual-platform assay using the Orphee Mythic 18 veterinary haematology analyser. The single platform assays were more precise with decreased intra-assay variability compared with ANC obtained using the dual protocol. Defining ANC based on Ly6G expression produces a 15% higher estimate than the dual protocol. Allowing for this difference in ANC definition, the flow cytometry counting assays using Ly6G can be used reliably in the research laboratory to quantify mouse ANC from a small volume of blood. We demonstrate the utility of the volumetric protocol in a time-course study of chemotherapy induced neutropenia using four drug regimens. © 2014 International Society for Advancement of Cytometry.

Dioxin-Induced Changes in Epididymal Sperm Count and Spermatogenesis  

PubMed Central

Background A single in utero exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on gestation day 15 decreased epididymal sperm count in adult rats and thus was used to establish a tolerable daily intake for TCDD. However, several laboratories have been unable to replicate these findings. Moreover, conflicting reports of TCDD effects on daily sperm production suggest that spermatogenesis may not be as sensitive to the adverse effects of TCDD as previously thought. Data sources We performed a PubMed search using relevant search terms linking dioxin exposure with adverse effects on reproduction and spermatogenesis. Data synthesis Developmental exposure to TCDD is consistently linked with decreased cauda epididymal sperm counts in animal studies, although at higher dose levels than those used in some earlier studies. However, the evidence linking in utero TCDD exposure and spermatogenesis is not convincing. Conclusions Animal studies provide clear evidence of an adverse effect of in utero TCDD exposure on epididymal sperm count but do not support the conclusion that spermatogenesis is adversely affected. The mechanisms underlying decreased epididymal sperm count are unknown; however, we postulate that epididymal function is the key target for the adverse effects of TCDD. PMID:20368131

Data analysis in emission tomography using emission-count posteriors  

NASA Astrophysics Data System (ADS)

A novel approach to the analysis of emission tomography data using the posterior probability of the number of emissions per voxel (emission count) conditioned on acquired tomographic data is explored. The posterior is derived from the prior and the Poisson likelihood of the emission-count data by marginalizing voxel activities. Based on emission-count posteriors, examples of Bayesian analysis including estimation and classification tasks in emission tomography are provided. The application of the method to computer simulations of 2D tomography is demonstrated. In particular, the minimum-mean-square-error point estimator of the emission count is demonstrated. The process of finding this estimator can be considered as a tomographic image reconstruction technique since the estimates of the number of emissions per voxel divided by voxel sensitivities and acquisition time are the estimates of the voxel activities. As an example of a classification task, a hypothesis stating that some region of interest (ROI) emitted at least or at most r-times the number of events in some other ROI is tested. The ROIs are specified by the user. The analysis described in this work provides new quantitative statistical measures that can be used in decision making in diagnostic imaging using emission tomography.

Effect on dissolution of tablet storage in counting machines.  

PubMed

The effects of storage in an automatic counting and dispensing machine on dissolution rates on five drug products with known or suspected bioequivalence problems were studied. Amitriptyline hydrochloride, digoxin, prednisone, hydrochlorothiazide, and tolbutamide tablets exposed and unexposed to automatic counting machines were collected from 10 pharmacies located in various parts of the country. A 60-tablet unexposed sample was taken from a previously unopened container and placed in a tight, light-resistant container. Another 60-tablet sample of the same brand and lot number was collected 30 days after the initial filling of the counting machine or when it had to be refilled, whichever came first. Each sample was tested for dissolution rate and content uniformity. Twenty-seven paired samples representing 23 lots from 10 manufacturers were collected. There were no substantial differences in dissolution rate or content uniformity between the exposed and unexposed samples. Average temperatures in the pharmacies during the three-month sampling period ranged from 72 to 79 degrees F. Storage times of the drug product samples in the automatic counting machines varied from 9 to 46 days. The environmental conditions to which these tablets were exposed had no noticeable effect on the dissolution of these formulations. PMID:6846373
