A new anisidine possessing benzothiaozle-based chemosensor (1) has been designed and synthesized. The chemosensor 1 was designed to provide hard base environment for ratiometric detection of comparatively less studied Al(3+) ions. In CH3CN, the fluorescence spectra of chemosensor 1 red shifted from 368 to 430 nm with addition of Al(3+) and Hg(2+) ions; while Cu(2+) ions caused quenching of emission intensity of 1. These differential changes observed with Al(3+) and Cu(2+) ions addition enabled chemosensor 1 to construct "NOR" and "TRANSFER" logic gates...

Accurate localization of parathyroid adenomas allows for minimally invasive parathyroidectomy. This results in a shorter length of stay and increased patient satisfaction. Preoperative Technetium (99mTc) sestamibi scans accurately localize parathyroid adenomas in 70 to 85 per cent of cases. If a patient has a negative scan, it is logical to believe that with a preoperative sestamibi injection, the gamma probe may fail to help find an adenoma. We hypothesized that the gamma probe would not be useful intraoperatively for patients with primary hyperparathyroidism (PHPTH) and a negative sestamibi scan...

The paper aims to provide an insight into the significance of having a simulation model to forecast the supply of registered nurses for health workforce planning policy using System Dynamics. A model is highly in demand to predict the workforce demand for nurses in the future, which it supports for complete development of a needs-based nurse workforce projection using Malaysia as a case study. The supply model consists of three sub-models to forecast the number of registered nurses for the next 15 years: training model, population model and Full Time Equivalent (FTE) model...

PURPOSE: Ultrasound imaging is an effective approach for diagnosing breast cancer, but it is highly operator-dependent. Recent advances in computer-aided diagnosis have suggested that it can assist physicians in diagnosis. Definition of the region of interest before computer analysis is still needed. Since manual outlining of the tumor contour is tedious and time-consuming for a physician, developing an automatic segmentation method is important for clinical application. METHODS: The present paper represents a novel method to segment breast ultrasound images...

The strong in-plane anisotropy of rhenium disulfide (ReS2) offers an additional physical parameter that can be tuned for advanced applications such as logic circuits, thin-film polarizers, and polarization-sensitive photodetectors. ReS2 also presents advantages for optoelectronics, as it is both a direct-gap semiconductor for few-layer thicknesses (unlike MoS2 or WS2) and stable in air (unlike black phosphorus). Raman spectroscopy is one of the most powerful characterization techniques to non-destructively and sensitively probe the fundamental photo-physics of a 2D material...

Mobile anchor path planning techniques have provided as an alternative option for node localization in wireless sensor networks (WSNs). In such context, path planning is a movement pattern where a mobile anchor node's movement is designed in order to achieve a maximum localization ratio possible with a minimum error rate. Typically, the mobility path planning is designed in advance, which is applicable when the mobile anchor has sufficient sources of energy and time. However, when the mobility movement is restricted or limited, a dynamic path planning design is needed...

This article examines how scientific knowledge drives creativity in the small but influential culinary movement of 'modernist cuisine'. Originating in the mid-1990s, modernist cuisine began with a small group of avant-garde chefs using science to produce wildly innovative culinary creations. Since then, many of the movement's innovations, as well as its more general 'science-based' approach to cooking, have gained adoption among a diverse range of culinary professionals. But while science has enabled modernist chefs to produce a wide array of innovations and refinements, the group's embrace of scientific values poses a potential threat to the subjective, intuition-driven logic of culinary creativity...

BACKGROUND: The salutary effects of resistance exercise training (RET) are well established, including increased strength and function; however, less is known regarding the effects of RET on mental health outcomes. Aerobic exercise has well-documented positive effects on anxiety, but a quantitative synthesis of RET effects on anxiety is needed. OBJECTIVES: To estimate the population effect size for resistance exercise training (RET) effects on anxiety and to determine whether variables of logical, theoretical, and/or prior empirical relation to anxiety moderate the overall effect...

Unconventional computing is about breaking boundaries in thinking, acting and computing. Typical topics of this non-typical field include, but are not limited to physics of computation, non-classical logics, new complexity measures, novel hardware, mechanical, chemical and quantum computing. Unconventional computing encourages a new style of thinking while practical applications are obtained from uncovering and exploiting principles and mechanisms of information processing in and functional properties of, physical, chemical and living systems; in particular, efficient algorithms are developed, (almost) optimal architectures are designed and working prototypes of future computing devices are manufactured...

The knowledge accumulated in West and East is incomplete in different ways. The mainstream Western approach has contributed the basis for modern science, but indications have appeared in the Western literature that something has been missing in it that Eastern thought could offer. This paper explores the similarities and differences between Eastern and Western approaches to knowledge and whether a trend exists toward their conjunction or convergence. I suggest that a process of conjunction of these different modes of exploration of what the concepts of 'Life and Mind' really entail, at the interface of philosophy and science, is taking place in the areas of information and biomathics...

Pain associated with integumentary wounds is highly prevalent yet it remains an area of significant unmet need within healthcare. Currently, systemically administered opioids are the mainstay of treatment. However, recent publications are casting opioids in a negative light given their high side effect profile, inhibition of wound healing, and association with accidental overdose, incidents that are frequently fatal. Thus, novel analgesic strategies for wound-related pain need to be investigated. The ideal methods of pain relief for wound patients are modalities that are topical, lack systemic side effects, non-invasive, self-administered, and display rapid onset of analgesia...

Cancer disparities research is motivated by persistent inequities in cancer outcomes by race, ethnicity, social status, neighborhood location, and other subpopulation characteristics. These inequities have proven to be persistent and difficult to alter. Part of the reason for the frustration with slow progress is a lack of appreciation of the long-term nature of the undertaking. It is highly likely that the disparities observed in adulthood find their origins in young adulthood, if not earlier. A long-term perspective is needed, recognizing that successes may take many years to realize...

Physicians' experience with high quality training in breastfeeding during their medical education is historically varied. The process of becoming a board-certified physician entails more than 20 years of education, and although medical school and residency training timelines and courses are relatively standardized across the United States and even internationally, breastfeeding education varies greatly across schools and programs. The Academy of Breastfeeding Medicine (ABM) exists, in part, because historically, physicians have received too little clinical training in breastfeeding and infant nutrition...

Harnessing buckling instability in soft materials offers an effective strategy to achieve multifunctionality. Despite great efforts in controlling the wrinkling behaviors of film-based systems and buckling of periodic structures, the benefits of classical plate buckling in soft materials remain largely unexplored. The challenge lies in the intrinsic indeterminate characteristics of buckling, leading to geometric frustration and random orientations. Here, we report the controllable global order in constrained buckling of arrays of parallel plates made of hydrogels and elastomers on rigid substrates...

Research in biogerontology has largely focused on the complex relationship between mitochondrial dysfunction and biological aging. In particular, the mitochondrial free radical theory of aging (MFRTA) has been well accepted. However, this theory has been challenged by recent studies showing minimal increases in reactive oxygen species (ROS) as not entirely deleterious in nature, and even beneficial under the appropriate cellular circumstances. To assess these significant and nonintuitive observations in the context of a functional system, we have taken an in silico approach to expand the focus of the MFRTA by including other key mitochondrial stress response pathways, as they have been observed in the nematode Caenorhabditis elegans...

This article examines an argument which may negatively influence measles vaccination uptake. According to the argument, an individual child in a highly vaccinated society may be better off by being non-vaccinated; the child does not risk vaccine adverse effects and is protected against measles through herd immunity. Firstly, the conclusion of the argument is challenged by showing that herd immunity's protection is unreliable and inferior to vaccination. Secondly, the logic of the argument is challenged by showing that the argument is inherently self-defeating and therefore logically inconsistent...

Pharmacogenomics holds promise as a critical component of precision medicine. Yet, the use of pharmacogenomics in routine clinical care is minimal, partly due to the lack of efficient and effective use of existing evidence. This paper describes the design, development, implementation and evaluation of a knowledge-based system that fulfills three critical features: a) providing clinically relevant evidence, b) applying an evidence-based approach, and c) using semantically computable formalism, to facilitate efficient evidence assessment to support timely decisions on adoption of pharmacogenomics in clinical care...

BACKGROUND: This paper addresses the problem of finding attractors in biological regulatory networks. We focus here on non-deterministic synchronous and asynchronous multi-valued networks, modeled using automata networks (AN). AN is a general and well-suited formalism to study complex interactions between different components (genes, proteins,...). An attractor is a minimal trap domain, that is, a part of the state-transition graph that cannot be escaped. Such structures are terminal components of the dynamics and take the form of steady states (singleton) or complex compositions of cycles (non-singleton)...
