BACKGROUND: Seed location filtering is critical in DNA read mapping, a process where billions of DNA fragments (reads) sampled from a donor are mapped onto a reference genome to identify genomic variants of the donor. State-of-the-art read mappers 1) quickly generate possible mapping locations for seeds (i.e., smaller segments) within each read, 2) extract reference sequences at each of the mapping locations, and 3) check similarity between each read and its associated reference sequences with a computationally-expensive algorithm (i...

The current study explored the intellectual factors in false memories of 139 patients with schizophrenia, using a recognition task and an IQ test. The full-scale IQ score of the participants ranged from 57 to 144 (M = 100, SD = 14). The full IQ score had a negative correlation with false recognition in patients with schizophrenia, and positive correlations with high-confidence true recognition and discrimination rates. Further analyses with the subtests' scores revealed that false recognition was negatively correlated with scores of performance IQ (and one of its subtests: picture arrangement), whereas true recognition was positively correlated with scores of verbal IQ (and two of its subtests: information and digit span)...

BACKGROUND: Both amnestic mild cognitive impairment (aMCI) and schizophrenia, in particular deficit schizophrenia, are accompanied by cognitive impairments. The aim of the present study was to examine the cognitive differences between aMCI and (non)deficit schizophrenia. METHODS: Towards this end we recruited 60 participants with aMCI, 40 with deficit and 40 with nondeficit schizophrenia and 103 normal volunteers. Cognitive measures were assessed with the Consortium to Establish a Registry for Alzheimer's disease (CERAD) using the Verbal Fluency Test (VFT), Boston Naming Test (BNT), Mini-Mental State Examination (MMSE), Word list memory (WLM), Word list recall (WLRecall) and Word list recognition (WLRecognition)...

The Delusional Misidentification Syndromes (DMSs) are characterized by defective integration of the normally The Delusional Misidentification Syndromes (DMSs) are characterized by defective integration of the normally fused functions of perception and recognition. The classical sub-types are: the syndromes of Capgras, Fregoli,Intermetamorphosis (mentioned in 3) and Subjective doubles. These syndromes occur in a clear sensorium and shouldbe differentiated from the banal transient misidentifications occurring in confusional states and in mania and from thenon-delusional misidentifications (e...

False memories endorsed with higher confidence are more likely to be corrected by feedback than those endorsed with lower confidence (hypercorrection effect). Errors made with high confidence and correct responses made with low confidence are both associated with large meta-memory mismatches. Therefore, they both represent a type of unexpected event which automatically captures participant attention, such that correct information provided via feedback is well-encoded. On the other hand, a study that measured participants' perceived practical value for items suggested that voluntary allocation of attention might involve the hypercorrection effect...

Previous studies have suggested sentential complementation is the crucial ingredient of language that relates to false-belief (FB) reasoning, while the role of relative clauses (RCs) is less clear. Nevertheless, under the hypothesis that clausal embedding has a meta-representational effect, arguably implied in FB, one expects a link between FB and not only complementation but also relativization. Seventeen children with ASD (6 to 16 years, mean age 9;2) were assessed for RCs and FB. Comprehension of RCs significantly predicted FB performance, while none of the controlled factors played a predictive role (comprehension of simple sentences, vocabulary, morpho-syntax and working memory)...

We earlier reported that the male mice lacking the Wdr13 gene ( Wdr13 -/0 ) showed mild anxiety, better memory retention, and up-regulation of synaptic proteins in the hippocampus. With increasing evidences from parallel studies in our laboratory about the possible role of Wdr13 in stress response, we investigated its role in brain. We observed that Wdr13 transcript gets up-regulated in the hippocampus of the wild-type mice exposed to stress. To further dissect its function, we analyzed the behavioral and molecular phenotypes of Wdr13 -/0 mice when subjected to mild chronic psychological stress, namely; mild (attenuated) social isolation...

BACKGROUND: Genetic variations in apolipoprotein E (APOE) and proximal genes (PVRL2, TOMM40, and APOC1) are associated with cognitive function and dementia, particularly Alzheimer's disease. Epigenetic mechanisms such as DNA methylation play a central role in the regulation of gene expression. Recent studies have found evidence that DNA methylation may contribute to the pathogenesis of dementia, but its association with cognitive function in populations without dementia remains unclear...

Social categorization appears to be an automatic process that occurs during person perception. Understanding social categorization better is important because mere categorization can lead to stereotype activation and, in turn, to discrimination. In the present study we used a novel approach to examine event-related potentials (ERPs) of gender categorization in the "Who said what?" memory paradigm, thus allowing for a more in-depth understanding of the specific mechanisms underlying identity versus categorization processing...

BACKGROUND: Both subjective cognitive decline (SCD) and a family history of Alzheimer's disease (AD) portend risk of brain abnormalities and progression to dementia. Posterior default mode network (pDMN) connectivity is altered early in the course of AD. It is unclear whether SCD predicts similar outcomes in cognitively normal individuals with a family history of AD. METHODS: We studied 124 asymptomatic individuals with a family history of AD (age 64 ± 5 years)...

Studies of social judgments have demonstrated a number of diverse phenomena that were so far difficult to explain within a single theoretical framework. Prominent examples are false consensus and false uniqueness, as well as self-enhancement and self-depreciation. Here we show that these seemingly complex phenomena can be a product of an interplay between basic cognitive processes and the structure of social and task environments. We propose and test a new process model of social judgment, the social sampling model (SSM), which provides a parsimonious quantitative account of different types of social judgments...

BACKGROUND: Gastric adenocarcinoma is a heterogenous disease that results from complex interactions between environmental and genetic factors, which may contribute to the disparate outcomes observed between different patient populations. This study aimed to determine whether genomic differences exist in a diverse population of patients by evaluating tumor mutational profiles stratified by race. METHODS: All patients with gastric adenocarcinoma between 2012 and 2016 who underwent targeted next-generation sequencing of cancer genes by the Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets platform were identified...

Background: End-stage renal disease (ESRD) is a serious public health problem, which can often lead to multiorgan dysfunction, such as cerebrovascular disease and cognitive damage. It is essential to understand cognitive impairment in patients with ESRD to develop better ESRD treatment and prevent further cognitive impairment. Cognitive impairment is believed to be related to structural abnormalities in the brain. Purpose: To investigate white matter microstructural abnormalities in patients with ESRD using TBSS analysis of DTI and to explore the possible mechanisms underlying the impaired cognitive function...

Discrepancies between expectations and outcomes, or prediction errors, are central to trial-and-error learning based on reward and punishment, and their neurobiological basis is well characterized. It is not known, however, whether the same principles apply to declarative memory systems, such as those supporting semantic learning. Here, we demonstrate with fMRI that the brain parametrically encodes the degree to which new factual information violates expectations based on prior knowledge and beliefs-most prominently in the ventral striatum, and cortical regions supporting declarative memory encoding...

Three experiments investigated the relationship between future thinking and false memories. In Experiment 1, participants remembered familiar events (e.g., a holiday) from their past, imagined planning the same events in the future, or took part in a control condition in which they visualized typical events. They then rated a series of schema-related and schema-unrelated nouns for how likely they were to be encountered within those events. In a surprise recognition test, participants in the future condition falsely recognized more schema-related items than participants in the past and control conditions...

The present study examined the mnemonic consequences of true/false denials and affirmatives on how a listener appraises their personal past. To this end, participants (listeners) rated the extent to which they were confident certain events occurred during their childhood. They rated these events both before and after a confederate (speaker) denied or affirmed the occurrence of four different childhood events each, for a total of eight "rehearsed" events. For each set (denials and affirmatives) of events, half were true and half were false...

Faces are among the most relevant social stimuli revealing an encounter's identity and actual emotional state. Deficits in facial recognition may be an early sign of cognitive decline leading to social deficits. The main objective of the present study is to investigate if individuals with amnestic mild cognitive impairment show recognition deficits in facial identity. Thirty-seven individuals with amnestic mild cognitive impairment, multiple-domain (15 female; age: 75±8 yrs.) and forty-one healthy volunteers (24 female; age 71±6 yrs...

It is widely assumed that context reinstatement benefits memory, but our experiments revealed that context reinstatement can systematically distort memory. Participants viewed pictures of objects superimposed over scenes, and we later tested their ability to differentiate these old objects from similar new objects. Context reinstatement was manipulated by presenting objects on the reinstated or switched scene at test. Not only did context reinstatement increase correct recognition of old objects, but it also consistently increased incorrect recognition of similar objects as old ones...

This paper focuses on developing an anti-velocity jamming strategy that enhances the ability of a pulse-Doppler (PD) radar to detect moving targets in the presence of translational and/or micro motion velocity jamming generated by the digital radio frequency memory (DRFM) repeat jammers. The strategy adopts random pulse initial phase (RPIP) pulses as its transmitted signal and thus gets DRFM jammers not adaptable to the randomness of initial phase of the transmitted pulses in the pulse repetition interval (PRI) domain...
