MULTIGENERATIONAL EFFECTS OF CARBENDAZIM IN DAPHNIA MAGNA: FROM A SUBCELLULAR TO A POPULATION LEVEL.

Environ Toxicol Chem 2018 Dec 3. Epub 2018 Dec 3.

Department of Biology & CESAM, University of Aveiro, 3810-193 Aveiro, Portugal.

Anthropogenic activities such as the use of pesticides may affect in some way aquatic biota populations, due to potential agricultural runoffs or disposals. Carbendazim is one example of a widely used fungicide with a high potential to end up in aquatic ecosystems through runoff. Deleterious effects observed at the individual level are possibly explained by changes in homeostasis at cellular and both can then be used to predict effects at the population level. Read More

Differential capacitance of ionic liquids according to lattice-gas mean-field model with nearest-neighbor interactions.

J Chem Phys 2018 Nov;149(20):204703

Department of Physics, North Dakota State University, Fargo, North Dakota 58108, USA.

The Bragg-Williams free energy is used to incorporate nearest-neighbor interactions into the lattice gas model of a solvent-free ionic liquid near a planar electrode. We calculate the differential capacitance from solutions of the mean-field consistency relation, arriving at an explicit expression in the limit of a weakly charged electrode. The two additional material parameters that appear in the theory-the degree of nonideality and the resistance to concentration changes of each ion type-give rise to different regimes that we identify and discuss.

Vanishing Density of States in Weakly Disordered Weyl Semimetals.

Phys Rev Lett 2018 Nov;121(21):215301

Institute for Theoretical Physics, Universität zu Köln, D-509237 Köln, Germany.

The Brillouin zone of the clean Weyl semimetal contains points at which the density of states (DOS) vanishes. Previous work suggested that below a certain critical concentration of impurities this feature is preserved including in the presence of disorder. This result got criticized for its neglect of rare disorder fluctuations which might bind quantum states and hence generate a finite DOS. Read More

Disentangling Genuine from Matter-Induced CP Violation in Neutrino Oscillations.

Phys Rev Lett 2018 Nov;121(21):211802

Department of Theoretical Physics, University of Valencia and IFIC, University Valencia-CSIC, Burjassot, 46100 Valencia, Spain.

We prove that, in any flavor transition, neutrino oscillation CP-violating asymmetries in matter have two disentangled components: (i) a CPT-odd T-invariant term, non-vanishing iff there are interactions with matter, and (ii) a T-odd CPT-invariant term, non-vanishing iff there is genuine CP violation. As function of the baseline, these two terms are distinct L-even and L-odd observables to separately test (i) matter effects sensitive to the neutrino hierarchy and (ii) genuine CP violation in the neutrino sector. For the golden ν_{μ}→ν_{e} channel, the different energy distributions of the two components provide a signature of their separation. Read More

Fachbereich Chemie, Philipps-Universität Marburg, Hans-Meerwein-Straße 4, 35032 Marburg, Germany.

Evolutionary crystal structure prediction methods combined with density functional theory (DFT) calculations reveal a high-pressure (hp) phase of the intermetallic compound UCo crystalizing in the NaTl structure type ([Formula: see text]). We predict this compound to be formed at pressures below 9 GPa. Hp-UCo shows the same structural trends as the two experimentally known pseudo-binary compounds UCoRh and UNiPt. Read More

Functionalized MXenes as ideal electrodes for Janus MoSSe.

Phys Chem Chem Phys 2018 Dec 5. Epub 2018 Dec 5.

School of Physics, State Key Laboratory of Crystal Materials, Shandong University, Jinan 250100, China.

On the basis of first-principles calculations, we examined the possibility of functionalized transition metal carbides and nitrides (f-MXenes) as ideal electrode materials for two-dimensional (2D) Janus MoSSe through interfacial electronic properties and Schottky barriers within MoSSe/f-MXene van der Waals (vdW) heterostructures. We found that the interactions between MoSSe and f-MXenes are weak, and thus the intrinsic electronic features of MoSSe could be reserved. Based on band structure calculations, the minus n-type (vanishing) Schottky barrier heights could be assigned to MoSSe/Ti2C(OH)2 and MoSSe/Mo2C(OH)2, and the p-type Schottky barrier height assigned to Sc2NO2 turns out to be negligible.

The Changing Educators' Work Environment in Contemporary Society.

Front Psychol 2018 13;9:2186. Epub 2018 Nov 13.

Department of Human Sciences, University of Verona, Verona, Italy.

In this paper, we are going to address job satisfaction and perceived self-efficacy withinthe context of residential child-care. A joint report from the European Foundation for the Improvement on Living and Working Conditions and the European Agency for Safety and Health at Work revealed that managers in the field of health and education were the most concerned about the psychosocial risk of their employees, although concern is not automatically translated into tools to face the risk and to manage it. So, measuring and improving employees' job satisfaction and self-efficacy can be an important means for organizations to prevent the outcomes of psychosocial risk, and supporting high quality performance of workers.

Department of Physics & Astronomy/3905, 1000 E. University Avenue, University of Wyoming, Laramie, WY 82071, USA.

Because of the importance of ferromagnetism at room temperature, we search for new materials that can exhibit a non-vanishing magnetic moment at room temperature and at the same time can be used in spintronics. The experimental results indicate that d0 ferromagnetism without any magnetic impurities takes place in PbS films made of close-packed lead sulfide nanoparticles of 30 nm. To explain the existence of the d0 ferromagnetism, we propose a model where various PbS bulk and surface configurations of Pb-vacancies are analyzed. Read More

Paramagnon-Enhanced Spin Currents in a Lattice near the Curie Point.

Sci Rep 2018 Nov 20;8(1):17108. Epub 2018 Nov 20.

LNESS-Physics Department, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133, Milano, Italy.

Spin transport phenomena have been shown to be highly enhanced when the temperature approaches the Curie point of the material sustaining a spin flow. Here we propose a simple - yet unifying - explanation for such enhancements, based on a random-phase model accounting for the spin fluctuations within a ferromagnetic material in the paramagnetic phase. We show that pure spin currents carried by conduction electrons injected into a paramagnetic lattice of mutually interacting localized magnetic moments can be enhanced close to the Curie temperature by the exchange interaction between the lattice sites and the non vanishing spin density associated with the spin current.

Plastic deformation of a permanently bonded network: Stress relaxation by pleats.

J Chem Phys 2018 Nov;149(18):184503

TIFR Centre for Interdisciplinary Sciences, 36/P Gopanapally, Hyderabad 500107, India.

We show that a flat two dimensional network of connected vertices, when stretched, may deform plastically by producing "pleats", system spanning linear structures with width comparable to the lattice spacing, where the network overlaps on itself. To understand the pleating process, we introduce an external field that couples to local displacements, i.e. Read More

Multi-Cell Multi-Task Convolutional Neural Networks for Diabetic Retinopathy Grading.

Conf Proc IEEE Eng Med Biol Soc 2018 Jul;2018:2724-2727

Diabetic Retinopathy (DR) is a non-negligible eye disease among patients with Diabetes Mellitus, and automatic retinal image analysis algorithm for the DR screening is in high demand. Considering the resolution of retinal image is very high, where small pathological tissues can be detected only with large resolution image and large local receptive field are required to identify those late stage disease, but directly training a neural network with very deep architecture and high resolution image is both time computational expensive and difficult because of gradient vanishing/exploding problem, we propose a Multi-Cell architecture which gradually increases the depth of deep neural network and the resolution of input image, which both boosts the training time but also improves the classification accuracy. Further, considering the different stages of DR actually progress gradually, which means the labels of different stages are related. Read More

Tissue-Level Mechanosensitivity: Predicting and Controlling the Orientation of 3D Vascular Networks.

Nano Lett 2018 Nov 26. Epub 2018 Nov 26.

Department of Biomedical Engineering , Technion-Israel Institute of Technology , Haifa , 3200002 , Israel.

Understanding the mechanosensitivity of tissues is a fundamentally important problem having far-reaching implications for tissue engineering. Here we study vascular networks formed by a coculture of fibroblasts and endothelial cells embedded in three-dimensional biomaterials experiencing external, physiologically relevant forces. We show that cyclic stretching of the biomaterial orients the newly formed network perpendicular to the stretching direction, independent of the geometric aspect ratio of the biomaterial's sample.

Flexural phonons in supported graphene: from pinning to localization.

Sci Rep 2018 Nov 2;8(1):16256. Epub 2018 Nov 2.

Department of Physics & Astronomy, Texas A&M University, College Station, TX, 77843-4242, USA.

We identify graphene layer on a disordered substrate as a system where localization of phonons can be observed. Generally, observation of localization for scattering waves is not simple, because the Rayleigh scattering is inversely proportional to a high power of wavelength. The situation is radically different for the out of plane vibrations, so-called flexural phonons, scattered by pinning centers induced by a substrate. Read More

Phys Rev Lett 2018 Oct;121(16):166401

Institut für Physik, Universität Augsburg, D-86135 Augsburg, Germany.

The average density of states in a disordered three-dimensional Weyl system is discussed in the case of a continuous distribution of random scattering. Our results clearly indicate that the average density of states does not vanish, reflecting the absence of a critical point for a metal-insulator transition. This calculation supports recent suggestions of an avoided quantum critical point in the disordered three-dimensional Weyl semimetal. Read More

Topological insulator with negative spin-orbit coupling and transition between Weyl and Dirac semimetals in InGaN-based quantum wells.

Sci Rep 2018 Oct 18;8(1):15403. Epub 2018 Oct 18.

Faculty of Physics, University of Warsaw, ul. Pasteura 5, 02-093, Warszawa, Poland.

We study the influence of negative spin-orbit coupling on the topological phase transition and properties of the topological insulator state in InGaN-based quantum wells grown along c axis of the wurtzite lattice. The realistic eight-band k·p method with relativistic and nonrelativistic linear-k terms is employed. Our calculations show that the negative spin-orbit coupling in InN is not an obstacle to obtain the topological insulator phase in InN/InGaN and InGaN/GaN quantum wells. Read More

In situ, time-resolved, x-ray diffraction and simultaneous continuum measurements were used to examine structural changes in Si shock compressed to 54 GPa. Shock melting was unambiguously established above ∼31-33  GPa, through the vanishing of all sharp crystalline diffraction peaks and the emergence of a single broad diffraction ring. Reshock from the melt boundary results in rapid (nanosecond) recrystallization to the hexagonal-close-packed Si phase and further supports melting. Read More

Holistic CNN Compression via Low-rank Decomposition with Knowledge Transfer.

IEEE Trans Pattern Anal Mach Intell 2018 Oct 1. Epub 2018 Oct 1.

Convolutional neural networks (CNNs) have achieved remarkable success in various computer vision tasks, which are extremely powerful to deal with massive training data by using tens of millions of parameters. However, CNNs often cost significant memory and computation consumption, which prohibits their usage in resource-limited environments such as mobile or embedded devices. To address the above issues, the existing approaches typically focus on either accelerating the convolutional layers or compressing the fully-connected layers separatedly, without pursuing a joint optimum.

Experimental Observation of Topologically Protected Bound States with Vanishing Chern Numbers in a Two-Dimensional Quantum Walk.

Phys Rev Lett 2018 Sep;121(10):100501

Beijing Key Laboratory of Nanophotonics & Ultrafine Optoelectronic Systems, School of Physics, Beijing Institute of Technology, 100081 Beijing, China.

Quantum walks (QWs) provide a powerful tool as a quantum simulator to study and understand topological phases. Using such a quantum simulator, some topological phenomena have been discussed. However, all the experimental observations on the topological phenomena in QWs have been restricted to evolution in one dimension (1D) so far. Read More

Primordial Non-Gaussianities and Zero-Bias Tracers of the Large-Scale Structure.

Phys Rev Lett 2018 Sep;121(10):101301

Center for Computational Astrophysics, Flatiron Institute, 162 5th Avenue, New York, New York 10010, USA.

We develop a new method to constrain primordial non-Gaussianities of the local kind using unclustered tracers of the large scale structure. We show that, in the limit of low noise, zero bias tracers yield large improvement over standard methods, mostly due to vanishing sampling variance. We propose a simple technique to construct such a tracer, using environmental information obtained from the original sample and validate our method with N-body simulations. Read More

What is known about deferasirox chelation therapy in pediatric HSCT recipients: two case reports of metabolic acidosis.

Ther Clin Risk Manag 2018 7;14:1649-1655. Epub 2018 Sep 7.

Bone Marrow Transplant Unit, Institute for Maternal and Child Health - IRCCS Burlo Garofalo, Trieste, Italy,

To date, in pediatric field, various hematological malignancies are increasingly treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Iron overload and systemic siderosis often occur in this particular cohort of patients and are associated with poor prognosis. We describe herein the case of two allo-HSCT patients, on treatment with deferasirox; they showed histopathological elements compatible with venoocclusive disease or vanishing bile duct syndrome in ductopenic evolution before deferasirox started.
