Dance, as aesthetic self-expression, is a unique arts-based program that combines the physical benefits of exercise with psychosocial therapeutic benefits. While dance has also been shown to support empowerment, meaningful self-expression, and pleasurable experience, it is rarely adopted to support these aspects of engagement in the context of dementia care. The instrumental reduction of dance to its application as a therapeutic tool can be traced to the contemporary movement towards cognitive science with an emphasis on embodied cognition...

Background: Biogeographers assess how species distributions and abundances affect the structure, function, and composition of ecosystems. Yet we face a major challenge: it is difficult to precisely map species across landscapes. Novel Earth observations could overcome this challenge for vegetation mapping. Airborne imaging spectrometers measure plant functional traits at high resolution, and these measurements can be used to identify tree species. In this paper, I describe a trait-based approach to species identification with imaging spectroscopy, the Center for Conservation Biology species identification (CCB-ID) method, which was developed as part of an ecological data science evaluation competition...

Integration of photonic chips with millimeter-scale atomic, micromechanical, chemical, and biological systems can advance science and enable new miniaturized hybrid devices and technology. Optical interaction via small evanescent volumes restricts performance in applications such as gas spectroscopy, and a general ability to photonically access optical fields in large free-space volumes is desired. However, conventional inverse tapers and grating couplers do not directly scale to create wide, high-quality collimated beams for low-loss diffraction-free propagation over many millimeters in free space, necessitating additional bulky collimating optics and expensive alignment...

Background: Aspirin has been revealed to probably decrease the risk of cholangiocarcinoma (CCC), which, nevertheless, is of controversy. To this end, a systematic review and meta-analysis was performed to investigate the above-described association. Methods: We thoroughly searched PubMed, EMBASE, and ISI Web of Science for relevant studies published prior to October 2017, followed by random-effects model for calculation of pooled ORs and corresponding 95% CIs. Additionally, subgroup and sensitivity analyses were carried out to confirm whether the outcomes were stable...

Force spectroscopy allows the manipulation of single molecules and the characterization of their properties and interactions thereby rendering it a powerful tool for biological sciences. Force spectroscopy at the level of individual molecules requires force resolution in the piconewton regime as achieved by optical tweezers (OT), magnetic tweezers (MT), and atomic force microscopy (AFM) with AFM providing the largest force range from tenth of piconewton to several micronewton. In membrane probe spectroscopy the commonly used sharp cantilever tip is replaced by a lipid-coated glass sphere...

BACKGROUND: Although dysfunction of amygdala-related circuits is centrally implicated in major depressive disorder (MDD), little is known about how this dysfunction differs between adult and adolescent MDD patients. METHODS: Voxel-wise meta-analyses of abnormal amygdala resting-state functional connectivity (rsFC) were conducted in adult and adolescent groups separately, followed by a quantitative meta-analytic comparison of the two groups. FINDINGS: Nineteen studies that included 665 MDD patients (392 adults and 273 adolescents) and 546 controls (341 adults and 205 adolescents) were identified in the current study...

Alternative separation methods operating in an aqueous environment are of increasing importance for further progress of molecular separation in life sciences and other industrial sectors working towards a biobased economy. By spincoating, membranes with thicknesses under 100 nm and 20 cm2 surface area were prepared from an epoxy based resin. For the first time such ultrathin epoxy films were used for the selective separation of small molecules and metabolites within an aqueous environment. Initially, selectivity is demonstrated by the separation of two dyes of similar size (0...

Natural variation in biological evidence leads to uncertain genotypes. Forensic comparison of a probabilistic genotype with a person's reference gives a numerical strength of DNA association. The distribution of match strength for all possible references usefully represents a genotype's potential information. But testing more genetic loci exponentially increases the number of multi-locus possibilities, making direct computation infeasible. At each locus, Bayesian probability can quickly assemble a match strength random variable...

Education in health informatics is an important contribution to the digital transformation in health care services, and there is a need to combine health and technology competencies. Traditional ways with separation of health sciences and computer science have shortcomings, and there is need for individuals with a holistic view and relevant education background for improving the technology-supported clinical work processes. This paper presents how the curriculum was organised in a course in "Understanding Technology", which was a part of a Master's Programme in Health Informatics...

CONTEXT: High vertical ground reaction force (vGRF) when initiating ground contact during jump-landing is one biomechanical factor that may increase risk of anterior cruciate ligament injury. Intervention programs have been developed to decrease vGRF to reduce injury risk, yet generating high forces is still critical for performing dynamic activities such as a vertical jump task. OBJECTIVE: To evaluate if a jump-landing feedback intervention, cueing a decrease in vGRF, would impair vertical jump performance in a separate task (Vertmax )...

INTRODUCTION: Overweight and obesity (OW/OB) rates are increasing among Canadian children and youth, with rates currently affecting one-third of 5-17 year olds. OW/OB is associated with numerous physical and psychosocial consequences, which are compounded when a child has a pre-existing disability. This is concerning considering children with disabilities experience OW/OB at two to three times the rate of their typically developing peers. While the number of weight management programs have been increasing, they are generally designed to meet the needs of typically developing children and often exclude children with disabilities...

Photo-responsive systems with adjustable self-assembly morphologies and tunable rheological properties have aroused widespread concern of researchers in recent years due to their prospect applications in controlled release, microfluidics, sensors, etc. In this paper, we combine cationic Gemini surfactant 12-3-12·2Br- and trans-2-methoxy-cinnamate (trans-OMCA) together to create a representative UV-responsive self-assembly system. The system displays abundant self-assemble behaviors and the self-assemblies with different states and different scales including wormlike micelles, vesicles, lytropic liquid crystals (LC) as well as aqueous two-phase system (ATPS) are observed even at lower surfactant concentration...

Standard models of complicated grief rely on a self-other divided mind that reflects the physical separateness of individuals. In these models, grief persists for those mourners who cannot reorganize self-and-other mental representations or adapt to identity changes after loss. However, advances in cognitive science indicate that relationships are often processed via distributed social-cognitive coding whereby individuals together form a psychologically extended common mind. I propose a novel "we" hypothesis in which shared representations, rather than self-other distinctions, shape the mind for a subgroup of mourners with complicated grief...
