Piotr de Silva, Tianyu Zhu, Troy Van Voorhis
One of the several problems that plague majority of density functional theory calculations is their inability to properly account for long-range correlations giving rise to dispersion forces. The recently proposed many-pair expansion (MPE) [T. Zhu et al., Phys. Rev. B 93, 201108(R) (2016)] is a hierarchy of approximations that systematically corrects any deficiencies of an approximate functional to finally converge to the exact energy. This is achieved by decomposing the total density into a sum of two-electron densities and accounting for successive two-, four-, six-,… electron interactions...

BACKGROUND: The influence of life events on suicidal behavior remains inconclusive, while reasons for living (RFL) may be protective. OBJECTIVES: To analyze the association between positive and negative life events and suicidal ideation (SI) and the interaction between life events and RFL on SI. METHOD: Patients with history of suicide attempts (n = 338) underwent a comprehensive clinical evaluation, including SI (Beck's Suicidal Ideation scale), RFL (Reasons for Living Inventory, RFLI) and life events (family, school, student or professional, social, health and religion-related and other life events) during the last twelve months...

Despite the recognition that behavioral and medical health conditions are frequently intertwined, the existing health care system divides management for these issues into separate settings. This separation results in increased barriers to receipt of care and contributes to problems of underdetection, inappropriate diagnosis, and lack of treatment engagement. Adolescents and young adults with mental health conditions have some of the lowest rates of treatment for their conditions of all age groups. Integration of behavioral health into primary care settings has the potential to address these barriers and improve outcomes for adolescents and young adults...

INTRODUCTION: The cardio-protective effect of alcohol has been the subject of a long-standing scientific controversy. Emerging evidence remains equivocal, as the validity of the dose-dependent J-shape association is tainted by conceptual, theoretical and methodological problems. A major impediment for a resolution on the matter is the lack of a life-long developmental approach to pinpoint alcohol's specific impact on the risk for cardio-vascular events (CVE). OBJECTIVE: Using retrospective and prospective individual-level data of alcohol consumption (AC) we applied a model-based clustering technique to uncover life-course trajectories of AC and explored their links to CVE...

This paper investigates the problem of robust observer-based passive control for uncertain singular time-delay system subject to actuator saturation. A polytopic approach is used to describe the saturation behavior. First, by constructing Lyapunov-Krasovskii functional, a less conservative sufficient condition is obtained which guarantees that the closed-loop system is regular, impulse free, stable and robust strictly passive. Then, with this condition, the design method of state feedback controller and the observer are given by solving linear matrix inequalities...

BACKGROUND: Opioid use is a significant problem in Alaska. Medication-assisted treatment for opioid use, including buprenorphine, reduces withdrawal symptoms and the harm associated with opioid abuse. Understanding consumers' treatment-seeking process is important for addressing barriers to treatment, facilitating effective service utilization, and informing policy. METHODS: To understand treatment-seeking behavior, we examined the attitudes, perceptions, and knowledge of those who would benefit from the medication-assisted treatment (MAT) buprenorphine...

BACKGROUND/AIM: In prevailing opinion, a strong relation exists between lack of empathy and antisocial personality disorder (ASPD). However, recent data fail to wholly clarify this relation, especially in consideration of empathy dimensions. In this study our aim was to address ASPD and social functionality from a contextual behavioral science viewpoint. MATERIALS AND METHODS: The present study was conducted with a sample of 34 individuals with ASPD and 32 healthy individuals as the control group...

The determination of shear wave speed is an important subject in the field of elastography, since elevated shear wave speeds can be directly linked to increased stiffness of tissues. MRI and ultrasound scanners are frequently used to detect shear waves and a variety of estimators are applied to calculate the underlying shear wave speed. The estimators can be relatively simple if plane wave behavior is assumed with a known direction of propagation. However, multiple reflections from organ boundaries and internal inhomogeneities and mode conversions can create a complicated field in time and space...

Oppositional defiant disorder (ODD) is a commonly diagnosed childhood behavior disorder, yet knowledge of relations between ODD and early neuropsychological functions, particularly independent of attention deficit/hyperactivity disorder (ADHD), is still limited. In addition, studies have not examined neuropsychological functioning as it relates to the different ODD symptom dimensions. Structural equation modeling was used to investigate how preschool neuropsychological functioning predicted negative affect, oppositional behavior, and antagonistic behavior symptom dimensions of ODD in 224 six-year-old children, oversampled for early behavior problems...

We provide the first validation data on the Spanish version of the Brief Problem Monitor-Parent form (BPM-P), a recently developed abbreviated version of the 120-item Child Behavior Checklist for Ages 6 to 18 (CBCL/6-18) in young schoolchildren. Parents of a community sample of 521 children aged 6-8 answered the CBCL/6-18 yearly, and the 19 BPM-P items were examined; parents also provided different measures of psychopathology. Confirmatory factor analysis of the expected 3-factor model (attention, externalizing, and internalizing) showed adequate fit (root mean square error of approximation, RMSEA ≤ ...

We used responses of two large samples of court-ordered participants from a statewide alcohol/driving safety program to investigate factor structure, score reliability, and criterion-related validity of the Short Inventory of Problems (SIP). Exploratory and confirmatory factor analyses, using both item-level and subscore-level data, support a one-factor structure for the SIP. Internal consistency score reliability estimates were consistent across samples and high enough to warrant use for making decisions about individuals...

Self-regulation can be conceptualized in terms of dynamic tension between highly probable reactions (prepotent responses) and use of strategies that can modulate those reactions (executive processes). This study investigated the value of a dynamical systems approach to the study of early childhood self-regulation. Specifically, ordinary differential equations (ODEs) were used to model the interactive influences of 115 36-month-olds' executive processes (strategy use) and prepotent responses to waiting to open a gift (desire for the gift and frustration about waiting to open it)...

Emotion expression is critical for the communication of important social information, such as emotional states and behavioral intentions. However, people tend to vary in their level of emotional expression. This meta-analysis investigated the relationships between levels of emotion expression and suppression, and social and interpersonal outcomes. PsycINFO databases, as well as reference lists were searched. Forty-three papers from a total of 3,200 papers met inclusion criteria, allowing for 105 effect sizes to be calculated...

Carly is a 5-year-old girl who presents for an interdisciplinary evaluation due to behaviors at school and home suggestive of attention-deficit hyperactivity disorder (ADHD). Parent report of preschool teacher concerns was consistent with ADHD. Psychological testing showed verbal, visual-spatial, and fluid reasoning IQ scores in the average range; processing speed and working memory were below average. Carly's behavior improved when her mother left the room, and she was attentive during testing with a psychologist...

Can the statistical properties of single-electron transfer events be correctly predicted within a common equilibrium ensemble description? This fundamental in nanoworld question of ergodic behavior is scrutinized within a very basic semi-classical curve-crossing problem. It is shown that in the limit of non-adiabatic electron transfer (weak tunneling) well-described by the Marcus-Levich-Dogonadze (MLD) rate the answer is yes. However, in the limit of the so-called solvent-controlled adiabatic electron transfer, a profound breaking of ergodicity occurs...

Diet and exercise are important for the wellbeing of people with cancer and their family caregivers. Unfortunately, little is known about their behaviors over time or factors that may influence their engagement in these behaviors. This exploratory study examined the influence of chronic conditions, symptom distress, and perceived social support on exercise and diet behaviors of patients with advanced cancer and their caregivers using the actor-partner interdependence mediation model (APIMeM) and interdependence theory as guiding frameworks...

: Auditory activity plays an important role in the development of the auditory system. Decreased activity can result from conductive hearing loss (CHL) associated with otitis media, which may lead to long-term perceptual deficits. The effects of CHL have been mainly studied at later stages of the auditory pathway, but early stages remain less examined. However, changes in early stages could be important because they would affect how information about sounds is conveyed to higher-order areas for further processing and localization...
