Livelihood intervention and mental well-being among women living with HIV in Delhi.

AIDS Care 2020 Oct 26:1-7. Epub 2020 Oct 26.

Emmanuel Hospital Association, New Delhi, India.

Poverty-alleviation programmes aimed to improved mental well-being among persons living with HIV (PLWH) in low and middle income countries have underscored the importance of understanding how and why such programmes work. We present findings from a six-month ethnographic process evaluation of , an economic livelihood programme locally designed to improve mental well-being among women affected by HIV in Delhi, India. In addition to benefits of improved economic standing, we found that supportive relationships cultivated among participants ( = 9) and with providers ( = 3) provided respite from worry about their illness and reframed what was relationally and practically possible in the context of living with HIV.

Solid-State NMR and NQR Spectroscopy of Lead-Halide Perovskite Materials.

J Am Chem Soc 2020 Nov 3;142(46):19413-19437. Epub 2020 Nov 3.

Department of Chemistry and Applied Biosciences, ETH Zürich, Vladimir Prelog Weg 1-5, Zurich CH-8093, Switzerland.

Two- and three-dimensional lead-halide perovskite (LHP) materials are novel semiconductors that have generated broad interest owing to their outstanding optical and electronic properties. Characterization and understanding of their atomic structure and structure-property relationships are often nontrivial as a result of the vast structural and compositional tunability of LHPs as well as the enhanced structure dynamics as compared with oxide perovskites or more conventional semiconductors. Nuclear magnetic resonance (NMR) spectroscopy contributes to this thrust through its unique capability of sampling chemical bonding element-specifically (H, C, N, Cl, K, Br, Rb, I, Cs, and Pb nuclei) and locally and shedding light onto the connectivity, geometry, topology, and dynamics of bonding.

Nanoprobing of MoS by Synchrotron Radiation When van der Waals Epitaxy Is Locally Invalid.

ACS Appl Mater Interfaces 2020 Jul 30;12(28):32041-32053. Epub 2020 Jun 30.

Department of Materials Science and Engineering, National Tsing-Hua University, Hsinchu 30013, Taiwan.

In this work, we demonstrated nano-scaled Laue diffractions by a focused polychromatic synchrotron radiation beam to discover what happens in MoS when van der Waals epitaxy is locally invalid. A stronger exciton recombination with a local charge depletion in the density of 1 × 10 cm, extrapolated by Raman scattering and photoluminescence, occurs in grains, which exhibits a preferred orientation of 30° rotation with respect to the -plane of a sapphire substrate. Else, the charge doping and trion recombination dominate instead. Read More

The Effects of Loading Conditions on the Behaviour of Fixed-Ended Plain Channel Columns.

Materials (Basel) 2020 Mar 21;13(6). Epub 2020 Mar 21.

Department of Aerospace Engineering, Universiti Putra Malaysia, Selangor 43400, Malaysia.

The compressive behaviour of column members can be considerably affected by local buckling, material yielding and local end conditions. In this paper, the effects of the loading conditions at the ends of plain channel section columns subjected to uniformly compressed loading, and fixed conditions at the column ends with respect to global rotations, was examined. Finite element simulation was employed to look at the post-buckled response of thin-walled, plain channel section columns that covered the complete loading history of the compression columns from the onset of elastic local buckling through the nonlinear elastic and elastoplastic post-buckling phases of behaviour to final collapse and unloading.

Addition of a surfactant to water increases the acaricidal activity of extracts of some plant species used to control ticks by Zimbabwean smallholder farmers.

BMC Vet Res 2019 Nov 9;15(1):404. Epub 2019 Nov 9.

Phytomedicine Programme, Faculty of Veterinary Science, University of Pretoria, Private Bag X04, Onderstepoort, Pretoria, 0110, South Africa.

Background: Many studies have revealed that bioactive compounds for different indications are not extracted from plants with water, the only extractant practically available to rural communities. We compared the acaricidal activity of acetone extracts of 13 species used traditionally to protect cattle against ticks. We also investigated if the extraction of biologically active compounds against Rhipicephalus (Boophilus) decoloratus ticks could be enhanced by adding a liquid soap that is locally available to smallholder farmers.

Modeling photoplethysmographic signals in camera-based perfusion measurements: optoelectronic skin phantom.

Biomed Opt Express 2019 Sep 2;10(9):4353-4368. Epub 2019 Aug 2.

Medical Information Technology (MedIT), Helmholtz-Institute for Biomedical Engineering, RWTH Aachen University, Aachen, Germany.

The remote acquisition of photoplethysmographic (PPG) signals via a video camera, also known as photoplethysmography imaging (PPGI), is not yet standardized. In general, PPGI is investigated with test persons in a laboratory setting. While these tests have the advantage of generating real-life data, they suffer from the lack of repeatability and are comparatively effort-intensive because human subjects are required. Read More

Visualizing Alzheimer's disease progression in low dimensional manifolds.

Heliyon 2019 Aug 2;5(8):e02216. Epub 2019 Aug 2.

Banner Alzheimer's Institute, USA.

While tomographic neuroimaging data is information rich, objective, and with high sensitivity in the study of brain diseases such as Alzheimer's disease (AD), its direct use in clinical practice and in regulated clinical trial (CT) still has many challenges. Taking CT as an example, unless the relevant policy and the perception of the primary outcome measures change, the need to construct univariate indices (out of the 3-D imaging data) to serve as CT's primary outcome measures will remain the focus of active research. More relevant to this current study, an overall global index that summarizes multiple complicated features from neuroimages should be developed in order to provide high diagnostic accuracy and sensitivity in tracking AD progression over time in clinical setting.

Optimal designs in three-level cluster randomized trials with a binary outcome.

Stat Med 2019 09 4;38(20):3733-3746. Epub 2019 Jun 4.

Division of Public Health Sciences, Department of Surgery, Washington University School of Medicine, St. Louis, Missouri.

Cluster randomized trials (CRTs) were originally proposed for use when randomization at the subject level is practically infeasible or may lead to a severe estimation bias of the treatment effect. However, recruiting an additional cluster costs more than enrolling an additional subject in an individually randomized trial. Under budget constraints, researchers have proposed the optimal sample sizes in two-level CRTs. Read More

Learning Visual Instance Retrieval from Failure: Efficient Online Local Metric Adaptation from Negative Samples.

IEEE Trans Pattern Anal Mach Intell 2020 Nov 23;42(11):2858-2873. Epub 2019 May 23.

Existing visual instance retrieval (VIR) approaches attempt to learn a faithful global matching metric or discriminative feature embedding offline to cover enormous visual appearance variations, so as to directly use it online on various unseen probes for retrieval. However, their requirement for a huge set of positive training pairs is very demanding in practice and the performance is largely constrained for the unseen testing samples due to the severe data shifting issue. In contrast, this paper advocates a different paradigm: part of the learning can be performed online but with nominal costs, so as to achieve online metric adaptation for different query probes.

Linking social and emotional learning standards to the WCSD Social-Emotional Competency Assessment: A Rasch approach.

Sch Psychol 2019 May;34(3):281-295

The Collaborative for Academic, Social, and Emotional Learning.

Growing interest in understanding the role of students' social-emotional competence for school success necessitates valid measures for large-scale use. We provide validity evidence for the 40-item Washoe County School District Social-Emotional Competency Assessment (WCSD-SECA), a student self-report measure that came from a researcher-practitioner partnership. The WCSD's social and emotional learning standards, which detail when and at what grade students are expected to express different competencies, contributed to hypotheses about the social-emotional competency levels targeted by the WCSD-SECA items.

A facile strategy for the synthesis of three-dimensional heterostructure self-assembled MoSe nanosheets and their application as an anode for high-energy lithium-ion hybrid capacitors.

Nanoscale 2019 Apr;11(15):7263-7276

State Key Laboratory of Advanced Processing and Recycling of Non-Ferrous Metals, Lanzhou University of Technology, Lanzhou 730050, P. R. China.

As energy storage devices, lithium-ion hybrid capacitors (LIHCs) are currently favored by researchers, because they combine the high energy density of lithium-ion batteries and the high power density as well as the long cycle life of electric double-layer capacitors. However, the reason that LIHCs are problematic for researchers and cannot be applied practically is the slow dynamic behavior of the battery type anode that leads to low magnification and cycle performance of the anode, furthermore, causing a dynamic imbalance between the Faraday embedded electrode and the capacitive electrode. Hence, it is imperative to find an anode material that can quickly intercalate/de-intercalate lithium. Read More

Dominant tree species drive beta diversity patterns in western Amazonia.

Ecology 2019 04 28;100(4):e02636. Epub 2019 Feb 28.

International Center for Tropical Botany, Florida International University, 4013 South Douglas Road, Miami, Florida, 33133, USA.

The forests of western Amazonia are among the most diverse tree communities on Earth, yet this exceptional diversity is distributed highly unevenly within and among communities. In particular, a small number of dominant species account for the majority of individuals, whereas the large majority of species are locally and regionally extremely scarce. By definition, dominant species contribute little to local species richness (alpha diversity), yet the importance of dominant species in structuring patterns of spatial floristic turnover (beta diversity) has not been investigated.

Menopause 2019 02;26(2):220-224

Laval University, Quebec City, Quebec, Canada.

The secretion of estrogens by the ovaries stops at menopause. Afterward, dehydroepiandrosterone (DHEA) becomes the only source of both estrogens and androgens during all the postmenopausal years. To maintain very low and biologically inactive concentrations of estrogens and androgens in the circulation, DHEA is transformed intracellularly into cell-specific small amounts of estrogens and androgens (except in the endometrium) which then act and are inactivated locally in the same cells, thus avoiding biologically significant systemic exposure to active sex steroids.

Kernel Clustering: Density Biases and Solutions.

IEEE Trans Pattern Anal Mach Intell 2019 01 6;41(1):136-147. Epub 2017 Dec 6.

Kernel methods are popular in clustering due to their generality and discriminating power. However, we show that many kernel clustering criteria have density biases theoretically explaining some practically significant artifacts empirically observed in the past. For example, we provide conditions and formally prove the density mode isolation bias in kernel K-means for a common class of kernels. Read More

Electronic properties of FeCl and CrO interacting with GaN nanotubes from density functional calculations.

J Mol Model 2018 Jul 4;24(8):192. Epub 2018 Jul 4.

Departamento de Física, Universidade Federal do Maranhão, 65080-805, São Luís, MA, Brazil.

The structural and electronic properties of FeCl and CrO interacting with (10,0) GaNNT were obtained using first principles calculations based on the density functional theory. The results show that for the CrO interacting with the GaNNT, the structure was locally deformed. However, in case of FeCl adsorbed with the GaNNT, the structure remained practically the same with the negligible deformation observed on tube surface. Read More

Quantization improves stabilization of dynamical systems with delayed feedback.

Chaos 2017 Nov;27(11):114306

Department of Applied Mechanics, Budapest University of Technology and Economics and MTA-BME Lendület Human Balancing Research Group, 1111 Budapest, Hungary.

We show that an unstable scalar dynamical system with time-delayed feedback can be stabilized by quantizing the feedback. The discrete time model corresponds to a previously unrecognized case of the microchaotic map in which the fixed point is both locally and globally repelling. In the continuous-time model, stabilization by quantization is possible when the fixed point in the absence of feedback is an unstable node, and in the presence of feedback, it is an unstable focus (spiral).

Potential landscape of high dimensional nonlinear stochastic dynamics with large noise.

Sci Rep 2017 Nov 17;7(1):15762. Epub 2017 Nov 17.

Key Laboratory of Systems Biomedicine Ministry of Education, Shanghai Center for Systems Biomedicine, Shanghai Jiao Tong University, Shanghai, 200240, China.

Quantifying stochastic processes is essential to understand many natural phenomena, particularly in biology, including the cell-fate decision in developmental processes as well as the genesis and progression of cancers. While various attempts have been made to construct potential landscape in high dimensional systems and to estimate transition rates, they are practically limited to the cases where either noise is small or detailed balance condition holds. A general and practical approach to investigate real-world nonequilibrium systems, which are typically high-dimensional and subject to large multiplicative noise and the breakdown of detailed balance, remains elusive.
