Surface states consisting of helical Dirac fermions have been extensively studied in three-dimensional topological insulators. Yet, experiments to date have only investigated fully formed topological surface states (TSS) and it is not known whether preformed or partially formed surface states can exist or what properties they could potentially host. Here, by decorating thin films of Bi2Se3 with nanosized islands of the same material, we show for the first time that not only can surface states exist in various intermediate stages of formation but they exhibit unique properties not accessible in fully formed TSS...

The origin of property enhancement of nanocomposite ion exchange membranes (IEMs) is far from being fully understood. By combining experimental work and computational modeling analysis, we could determine the influence of nanomaterials on the ion transport properties of nanocomposite cation exchange membranes (CEMs). We synthesized and characterized a series of nanocomposite CEMs by using SPPO as polymer materials and silica nanoparticles (NPs) (unsulfonated or sulfonated) as nanomaterials. We found that with the increase of NP loading, measured CEM permselectivity and swelling degree first increased and then decreased...

ISSUE: The Affordable Care Act has significantly increased health insurance coverage and access to care among U.S. adults nationwide. However, the law gives states flexibility in implementing certain provisions, leading to wide variations between states in consumers’ experiences. GOAL: To examine the differences in insurance coverage, access to care, and medical bill problems in the four largest states—California, Florida, New York, and Texas—all of which have made different choices in implementing the law...

This commentary reflects on the "elements" approach in psychological treatment research, and its specific application to a systematic review of psychosocial interventions for youth in conflict-affected areas. We discuss three key questions for the field. First, what psychological treatment elements are necessary and/or sufficient to achieve clinically significant change for a given population? Second, how should elements be sequenced to achieve optimal outcomes? Third, what might account for the large heterogeneity observed in psychological treatment trials, other than the constituent practice elements? We conclude by describing a new research programme that aims to develop a transdiagnostic intervention targeting common mental health difficulties among school-going adolescents in India...

Humans use multiple senses to navigate the social world, and the sense of smell is arguably the most underestimated one. An intriguing aspect of the sense of smell is its social communicative function. Research has shown that human odors convey information about a range of states (e.g., emotions, sickness) and traits (e.g., individuality, gender). Yet, what underlies the communicability of these states and traits via smell? We fill this explanatory gap with a framework that highlights the dynamic and flexible aspects of human olfactory communication...

This Account provides an overview of our recent efforts to uncover the fundamental charge transport properties of Si-Si and Ge-Ge single bonds and introduce useful functions into group 14 molecular wires. We utilize the tools of chemical synthesis and a scanning tunneling microscopy-based break-junction technique to study the mechanism of charge transport in these molecular systems. We evaluated the fundamental ability of silicon, germanium, and carbon molecular wires to transport charge by comparing conductances within families of well-defined structures, the members of which differ only in the number of Si (or Ge or C) atoms in the wire...

Jie Meng, Roman Casciano, Yi-Chien Lee, Lee Stern, Dmitry Gultyaev, Liyue Tong, Brice Kitio-Dschassi
BACKGROUND: Type 2 diabetes mellitus (T2DM) results in a substantial economic burden on patients, health care systems, and society. Most literature assessing the cost of T2DM focuses on the long-term complications of the disease, the association between glucose control and cost, and patient characteristics resulting in poor and costly outcomes. However, it is likely that attributes specific to diabetes therapy can affect the use of costly resources. OBJECTIVE: To estimate the effect of diabetes treatment-related attributes, such as improved efficacy, adherence, and reduced risk for hypoglycemia, on costs to T2DM patients...

The proliferation of new technology platforms and tools is dramatically advancing our ability to capture, integrate and use clinical and other health related data for research and care. Another critical and increasingly common source of data comes directly from patients - often in the form of Patient Reported Outcomes (PRO). As more providers and payers recognize that patient experiences reflect a critical dimension of the value proposition, these data are informing broader strategies to achieve performance improvement and accountability in health systems...

How do we decide what we perceive? Obviously, we base our decisions on sensory evidence. However, a new and surprising study by Hagura et al. shows that our perceptual decisions are also biased by the action costs that are associated with our decisions.

BACKGROUND: Ethics in nursing care are traditionally discussed in terms of moral norms or principles. When taking an ontological approach to ethics, ethics is about ethos. Ethos involves both an internal and an external side of ethics. Considering ethics and health from an ontological perspective can provide a different understanding of ethics and health in caring and nursing. Aim and research question: The aim of this study is to deepen the ontological understanding of ethics and health in caring and nursing...

Depression is a common and disabling complication of traumatic brain injury (TBI). The high rates of post-TBI depression (PTBID) make this condition an important candidate for selective preventive interventions. Areas covered: The authors recently reported on the efficacy of sertraline, a selective serotonin reuptake inhibitor (SSRI), for the prevention of new cases of depression in the first six months after TBI. The authors review this and other studies on preventive strategies in PTBID as ascertained from a PubMed and citation search...

Traumatic brain injury (TBI) is one of the leading causes of death and disability in children, and progressive hemorrhagic injury (PHI) post TBI is associated with poor outcomes. Therefore, the objective of this study was to develop and validate a prognostic model that uses the information available at admission to determine the likelihood of PHI occurrence after TBI in children. The identified demographic data, cause of injury, clinical predictors on admission, computed tomography scan characteristics, and routine laboratory parameters were collected and used to develop a PHI prognostic model with logistic regression analysis, and the prediction model was validated in 68 children...

OBJECTIVE: Cognitive behavioral therapy (CBT) is empirically supported for the treatment of anxiety disorders; however, not all individuals achieve recovery following CBT. Positive emotions serve a number of functions that theoretically should facilitate response to CBT - they promote flexible patterns of information processing and assimilation of new information, encourage approach-oriented behavior, and speed physiological recovery from negative emotions. We conducted a secondary analysis of an existing clinical trial dataset to test the a priori hypothesis that individual differences in trait positive emotions would predict CBT response for anxiety...

BACKGROUND: Social connections are important during the transition to parenthood. A wide body of literature suggests that these connections enhance health and contribute to wellbeing. In the case of parents and families, social connections can influence child development. Nurses and public health agencies are in a unique position to advocate for resources and approaches to enhance social connectivity for parents during this important life transition. OBJECTIVES: The aim of this review was to identify the universal social connectivity interventions that work, and the conditions that foster social connections for parents and enhance child development...

We examine false belief and counterfactual reasoning in children with autism with a new change-of-intentions task. Children listened to stories, for example, Anne is picking up toys and John hears her say she wants to find her ball. John goes away and the reason for Anne's action changes-Anne's mother tells her to tidy her bedroom. We asked, 'What will John believe is the reason that Anne is picking up toys?' which requires a false-belief inference, and 'If Anne's mother hadn't asked Anne to tidy her room, what would have been the reason she was picking up toys?' which requires a counterfactual inference...

INTRODUCTION: Renal papillary necrosis is not commonly seen in daily practice, but can have severe consequences when it is not diagnosed in time. It is known to be associated with sickle cell hemoglobinopathies; however a wide range of etiologies are possible, and it is therefore not the first diagnosis clinicians consider in patients with sickle cell disease who present with hematuria. METHODS: A literature search was performed to summarize the current knowledge about renal papillary necrosis associated with sickle cell disease...
