| detecting large quantum fisher information with finite measurement precision. | we propose an experimentally accessible scheme to determine the lower bounds on the quantum fisher information (qfi), which ascertains multipartite entanglement or usefulness for quantum metrology. the scheme is based on comparing the measurement statistics of a state before and after a small unitary rotation. we argue that, in general, the limited resolution of collective observables prevents the detection of large qfi. this can be overcome by performing an additional operation prior to the mea ... | 2016 | 26991166 |
| label-noise resistant logistic regression for functional data classification with an application to alzheimer's disease study. | alzheimer's disease (ad) is usually diagnosed by clinicians through cognitive and functional performance test with a potential risk of misdiagnosis. since the progression of ad is known to cause structural changes in the corpus callosum (cc), the cc thickness can be used as a functional covariate in ad classification problem for a diagnosis. however, misclassified class labels negatively impact the classification performance. motivated by ad-cc association studies, we propose a logistic regressi ... | 2016 | 26990925 |
| evaluation of presumably disease causing scn1a variants in a cohort of common epilepsy syndromes. | the scn1a gene, coding for the voltage-gated na+ channel alpha subunit nav1.1, is the clinically most relevant epilepsy gene. with the advent of high-throughput next-generation sequencing, clinical laboratories are generating an ever-increasing catalogue of scn1a variants. variants are more likely to be classified as pathogenic if they have already been identified previously in a patient with epilepsy. here, we critically re-evaluate the pathogenicity of this class of variants in a cohort of pat ... | 2016 | 26990884 |
| delta method and bootstrap in linear mixed models to estimate a proportion when no event is observed: application to intralesional resection in bone tumor surgery. | resecting bone tumors requires good cutting accuracy to reduce the occurrence of local recurrence. this issue is considerably reduced with a navigated technology. the estimation of extreme proportions is challenging especially with small or moderate sample sizes. when no success is observed, the commonly used binomial proportion confidence interval is not suitable while the rule of three provides a simple solution. unfortunately, these approaches are unable to differentiate between different uno ... | 2016 | 26990871 |
| complex-valued time-series correlation increases sensitivity in fmri analysis. | to develop a linear matrix representation of correlation between complex-valued (cv) time-series in the temporal fourier frequency domain, and demonstrate its increased sensitivity over correlation between magnitude-only (mo) time-series in functional mri (fmri) analysis. | 2016 | 26988705 |
| comparison on the use of semi-automated and automated core biopsy needle in ultrasound guided breast biopsy. | the aim of this study was to compare the use of semi-automated (medax velox 2; poggio rusco, italy) and automated (bard magnum biopsy instrument; covington, ga, usa) core biopsy needles, for ultrasound guided breast biopsy. | 2015 | 26988204 |
| a critical review of 20 years of parotid gland surgery. | conclusion pg surgery provides sufficient radicality with a minimum of functional loss. patient's outcome is associated with the reliable estimation of the lesional entity/dignity. diagnostic approaches are required to determine morphological aspects, avoid unnecessary surgery, and to reliable identify primary carcinomas/occult metastases. objectives the pre-operative assessment of parotid gland (pg) lesions is of major clinical impact, whilst surgery remains the diagnostic/therapeutic mainstay. ... | 2016 | 26986955 |
| nonparametric estimation of fisher information from real data. | the fisher information matrix (fim) is a widely used measure for applications including statistical inference, information geometry, experiment design, and the study of criticality in biological systems. the fim is defined for a parametric family of probability distributions and its estimation from data follows one of two paths: either the distribution is assumed to be known and the parameters are estimated from the data or the parameters are known and the distribution is estimated from the data ... | 2016 | 26986433 |
| confirmatory evidence for a multidimensional model of racial-ethnic socialization for transracially adoptive families. | the purpose of the current study is to test a recently established model of racial-ethnic socialization (langrehr, 2014) among 2 samples of white transracially adoptive parents and to assess whether the proposed model functions similarly after accounting for adopted child race. | 2016 | 26985870 |
| prediction of 60-day case fatality after aneurysmal subarachnoid hemorrhage: external validation of a prediction model. | external validation of prognostic models is crucial but rarely done. our aim was to externally validate a prognostic model to predict 60-day case fatality after aneurysmal subarachnoid hemorrhage developed from the international subarachnoid aneurysm trial in a retrospective unselected cohort of subarachnoid hemorrhage patients. | 2016 | 26985635 |

| comparison of hiv testing uptake in an urban academic emergency department using different testing assays and support systems. | despite 2006 recommendations by the centers for disease control and prevention for opt-out hiv testing in all healthcare settings, emergency department (ed) testing has been limited. we conducted an observational cohort study to assess the impact of two workflow interventions on the proportion of hiv tests ordered in an urban academic ed. first, a 4(th)-generation hiv antigen/antibody combination test replaced the existing assay, and ed staff continued to notify patients of their reactive tests. ... | 2016 | 26982908 |
| detection of mycobacterium ulcerans dna in the environment, ivory coast. | ivory coast is a west african country with the highest reported cases of buruli ulcer, a disabling subcutaneous infection due to mycobacterium ulcerans. however, the prevalence of environmental m. ulcerans is poorly known in this country. | 2016 | 26982581 |
| the inverted discoid meniscus segment: clinical, radiographic, and arthroscopic description of a hidden tear pattern. | a flipped, or inverted, meniscus segment is easily visualized in the normal meniscus. however, an inverted discoid meniscus segment may be difficult to appreciate because the tear occurs more centrally and leaves more meniscal rim; thus, it may be undertreated if not addressed during arthroscopy. | 2016 | 26980846 |
| aberrant activation-induced cytidine deaminase expression in philadelphia chromosome-positive b-cell acute lymphoblastic leukemia. | activation-induced cytidine deaminase (aid) is expressed in germinal center b cells and plays a critical role in somatic hypermutation and class-switch recombination of immunoglobulin genes. philadelphia chromosome-positive (ph+) acute lymphoblastic leukemia (all) carries a poor prognosis and is specifically treated with tyrosine kinase inhibitors. interestingly, aid has been shown to be aberrantly expressed and functional in ph+ all and is thought to contribute to genetic instability. we hypoth ... | 2016 | 26980048 |
| a morphological and immunophenotypic map of the immune response in merkel cell carcinoma. | the susceptibility of merkel cell carcinoma to the host immune response has prompted a search for effective immunotherapy. cd8-positive t lymphocytes are considered key effectors of this response, but the cellular infiltrates also harbor tumor-protective agents. by developing a comprehensive morphological and immunophenotypic map of tumor-infiltrating lymphocytes (tils) in merkel cell carcinoma, we aimed to establish a useful template for future studies. twenty-two cases (mean age, 79years [rang ... | 2016 | 26980039 |
| neurofibromin protein loss in desmoplastic melanoma subtypes: implicating nf1 allelic loss as a distinct genetic driver? | loss of the nf1 allele, coding for the protein neurofibromin, and polymorphism in the proto-oncogene ret (retp) are purportedly common in desmoplastic melanoma (dm). dm is categorized into pure (pdm) and mixed (mdm) subtypes, which differ in prognosis. most nf1 mutations result in a truncated/absent protein, making immunohistochemical screening for neurofibromin an ideal surrogate for nf1 allelic loss. using antineurofibromin, our aims were to ascertain the incidence of neurofibromin loss in dm ... | 2016 | 26980030 |
| efficient estimators for likelihood ratio sensitivity indices of complex stochastic dynamics. | we demonstrate that centered likelihood ratio estimators for the sensitivity indices of complex stochastic dynamics are highly efficient with low, constant in time variance and consequently they are suitable for sensitivity analysis in long-time and steady-state regimes. these estimators rely on a new covariance formulation of the likelihood ratio that includes as a submatrix a fisher information matrix for stochastic dynamics and can also be used for fast screening of insensitive parameters and ... | 2016 | 26979681 |
| enhancer of zeste homolog 2 (ezh2) expression in bladder cancer. | studies evaluating enhancer of zeste homolog 2 (ezh2) expression and oncologic outcomes in bladder cancer have been discrepant. ezh2 expression in noninvasive bladder cancer is not well studied. we thus set out to address the discrepancy in previous reports, and to study expression of ezh2 in noninvasive bladder cancer and its associations, in a large cystectomy cohort. | 2016 | 26976725 |
| descriptors of malignant non-mass enhancement of breast mri: their correlation to the presence of invasion. | this study aims to investigate the clinical significance of malignant non-mass enhancement (nme) descriptors in breast magnetic resonance images by assessing their correlation to the presence of invasion or lymph node metastasis. | 2016 | 26976623 |

| bacterial regulon modeling and prediction based on systematic cis regulatory motif analyses. | regulons are the basic units of the response system in a bacterial cell, and each consists of a set of transcriptionally co-regulated operons. regulon elucidation is the basis for studying the bacterial global transcriptional regulation network. in this study, we designed a novel co-regulation score between a pair of operons based on accurate operon identification and cis regulatory motif analyses, which can capture their co-regulation relationship much better than other scores. taking full adva ... | 2016 | 26975728 |
| gender recognition from facial images: two or three dimensions? | this paper seeks to compare encoded features from both two-dimensional (2d) and three-dimensional (3d) face images in order to achieve automatic gender recognition with high accuracy and robustness. the fisher vector encoding method is employed to produce 2d, 3d, and fused features with escalated discriminative power. for 3d face analysis, a two-source photometric stereo (ps) method is introduced that enables 3d surface reconstructions with accurate details as well as desirable efficiency. moreo ... | 2016 | 26974902 |
| integrating simultaneous prosocial and antisocial behavior into theories of collective action. | trust and cooperation constitute cornerstones of common-pool resource theory, showing that "prosocial" strategies among resource users can overcome collective action problems and lead to sustainable resource governance. yet, antisocial behavior and especially the coexistence of prosocial and antisocial behaviors have received less attention. we broaden the analysis to include the effects of both "prosocial" and "antisocial" interactions. we do so in the context of marine protected areas (mpas), ... | 2016 | 26973871 |
| changes in the expression of calcitonin gene-related peptide after exposure to injurious stretch-shortening contractions. | one of the factors that can result in musculoskeletal injuries, and time off work, is exposure to repetitive motion. the goal of this study was to determine if skeletal muscle injury induced by exposure to injurious stretch-shortening cycles (isscs), resulted in hyperalgesia in the hind limb and changes in calcitonin-gene related peptide (cgrp) immunolabeling in the dorsal root ganglia (drg) in young and old male rats. | 2016 | 26972633 |
| differential network analysis reveals the genome-wide landscape of estrogen receptor modulation in hormonal cancers. | several mutual information (mi)-based algorithms have been developed to identify dynamic gene-gene and function-function interactions governed by key modulators (genes, proteins, etc.). due to intensive computation, however, these methods rely heavily on prior knowledge and are limited in genome-wide analysis. we present the modulated gene/gene set interaction (magic) analysis to systematically identify genome-wide modulation of interaction networks. based on a novel statistical test employing c ... | 2016 | 26972162 |
