description: We investigate four young, but non-accreting, very low mass stars in Orion, which show irregular eclipses by circumstellar dust. The eclipses are not recurring periodically, are variable in depth, lack a flat bottom, and their duration is comparable to the typical timescale between eclipses. The dimming is associated with reddening consistent with dust extinction. Taken together this implies the presence of rings around these four stars, with radii ranging from 0.01 to 40 AU, comprised of optically thin dust clouds. The stars also show IR excess indicating the presence of evolved circumstellar disks, with orders of magnitude more material than needed for the eclipses. However, the rings need to cover an opening angle of about 20 degrees to explain how common these variable stars are in the coeval population in the same region, which is more extended than a typical disk. Thus, we propose that the rings may not be part of the disks, but instead separate structures with larger scale heights. To be sustained over years, the rings need to be replenished by dust from the disk or gravitationally bound to an object (e.g., planets or planetesimals). These four stars belong to a growing and diverse class of post-T Tauri stars with dips or eclipses in their lightcurves. Dusty rings with scale heights exceeding those of disks may be a common phenomenon at stellar ages between 5 and 10 Myr, in the transition from accretion disks to debris disks. These structures could be caused by migrating planets and may be signposts for the presence of young planetary systems.

description: In this work, we present expressions for radiative heat transfer between pairs of spheres in a linear chain and between individual spheres and their environment. The expressions are valid for coated spheres of arbitrary size, spacing, and isotropic optical properties. The spheres may be small and closely-spaced, which violates the assumptions foundational to classical radiative transfer. We validate our results against existing formulations of radiative heat transfer, namely the thermal discrete dipole and boundary element methods. Our results have important implications for the modeling and interpretation of near-field radiative heat transfer experiments between spherical bodies.

description: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a new second-line medication in the management of hyperglycemia in type 2 diabetes. These drugs can be associated with the development of diabetic ketoacidosis (DKA) with normal or moderately increased blood glucose levels. This is a life-threatening clinical condition termed euglycemic DKA, of which the diagnosis can be delayed due to the relative euglycemia. We report on two patients with type 2 diabetes who presented to the Emergency Department with malaise, nausea and vomiting. Both patients had been taking dapagliflozin for at least six months. A risk factor for the development of ketoacidosis, namely heavy alcohol consumption, was found in one of the patients. Arterial blood gas analysis showed severe metabolic acidosis with increased anion gap, positive serum and urine ketones and normal arterial lactate. The patients were treated in Internal Medicine with intravenous fluids, insulin, sodium bicarbonate and potassium. Dapagliflozin was stopped. Both patients recovered uneventfully. Even in the absence of significant hyperglycemia, accurate interpretation of arterial blood gas analysis and serum ketones should lead to correct diagnosis of euDKA.
Direct correlation functions and bridge functions in additive hard-sphere mixtures

description: A method to obtain (approximate) analytical expressions for the radial distribution functions in a multicomponent mixture of additive hard spheres that was recently introduced is used to obtain the direct correlation functions and bridge functions in these systems. This method, which yields results practically equivalent to the Generalized Mean Spherical Approximation and includes thermodynamic consistency, is an alternative to the usual integral equation approaches and requires as input only the contact values of the radial distribution functions and the isothermal compressibility. Calculations of the bridge functions for a binary mixture using the Boubl\'ık-Mansoori-Carnahan-Starling-Leland equation of state are compared to parallel results obtained from the solution of the Percus-Yevick equation. We find that the conjecture recently proposed by Guzmán and del R\'ıo (1998, {\em Molec. Phys.}, {\bf 95}, 645) stating that the zeros of the bridge functions occur approximately at the same value of the shifted distance for all pairs of interactions is at odds with our results. Moreover, in the case of disparate sizes, even the Percus-Yevick bridge functions do not have this property. It is also found that the bridge functions are not necessarily non-positive.

description: Initiating impact ionization of avalanche breakdown essentially requires applying a high electric field in a long active region, hampering carrier-multiplication with high gain, low bias and superior noise performance. Here we report the observation of ballistic avalanche phenomena in sub-MFP scaled vertical indium selenide (InSe)/black phosphorus (BP) heterostructures. The heterojunction is engineered to avalanche photodetectors (APD) and impact ionization transistors, demonstrating ultra-sensitive mid-IR light detection (4 μm wavelength) and ultra-steep subthreshold swing, respectively. These devices show an extremely low avalanche threshold (<1 volt), excellent low noise figures and distinctive density spectral shape. Further transport measurement evidences the breakdown originals from a ballistic avalanche phenomenon, where the sub-MFP BP channel enables both electrons and holes to impact-ionize the lattice and abruptly amplify the current without scattering from the obstacles in a deterministic nature. Our results shed light on the development of advanced photodetectors and efficiently facilitating carriers on the nanoscale.

description: In this paper, a one-phase Stefan-type problem for a semi-infinite material which has as its main feature a variable latent heat that depends on the power of the position and the velocity of the moving boundary is studied. Exact solutions of similarity type are obtained for the cases when Neumann or Robin boundary conditions are imposed at the fixed face. Required relationships between data are presented in order that these problems become equivalent to the problem where a Dirichlet condition at the fixed face is considered. Moreover, in the case where a Robin condition is prescribed, the limit behaviour is studied when the heat transfer coefficient at the fixed face goes to infinity.

Hexadecapole fluctuation mechanism for s-wave heavy fermion superconductor CeCu2Si2: Interplay between intra- and inter-orbital Cooper pairs

description: In heavy-fermion superconductors, it is widely believed that the superconducting gap function has sign-reversal due to the strong electron correlation. However, recently discovered fully-gapped s-wave superconductivity in CeCu2Si2 has clarified that strong attractive pairing interaction can appear even in heavy-fermion systems. To understand the origin of attractive force, we develop the multipole fluctuation theory by focusing on the inter-multipole many-body interaction called the vertex corrections. By analyzing the periodic Anderson model for CeCu2Si2, we find that hexadecapole fluctuations mediate strong attractive pairing interaction. Therefore, fully-gapped s-wave superconductivity is driven by pure on-site Coulomb repulsion, without introducing electron-phonon interactions. The present theory of superconductivity will be useful to understand rich variety of the superconducting states in heavy fermion systems.

description: Recent experiments on strongly coupled microwave and ferromagnetic resonance modes have focused on large volume bulk crystals such as yttrium iron garnet, typically of millimeter-scale dimensions. We extend these experiments to lower volumes of magnetic material by exploiting low-impedance lumped-element microwave resonators. The low impedance equates to a smaller magnetic mode volume, which allows us to couple to a smaller number of spins in the ferromagnet. Compared to previous experiments, we reduce the number of participating spins by two orders of magnitude, while maintaining the strength of the coupling rate. Strongly coupled devices with small volumes of magnetic material may allow the use of spin orbit torques, which require high current densities incompatible with existing structures.

description: We consider random walks on the infinite cluster of a conditional bond percolation model on the infinite ladder graph. In a companion paper, we have shown that if the random walk is pulled to the right by a positive bias $λ> 0$, then its asymptotic linear speed $\overline{\mathrm{v}}$ is continuous in the variable $λ> 0$ and differentiable for all sufficiently small $λ> 0$. In the paper at hand, we complement this result by proving that $\overline{\mathrm{v}}$ is differentiable at $λ= 0$. Further, we show the Einstein relation for the model, i.e., that the derivative of the speed at $λ= 0$ equals the diffusivity of the unbiased walk.
CMUT on Glass Substrate for Next-Generation Medical Imaging and Beyond
Creators: name: Zhang, Xiao
Publisher: name: arXiv
Year: 2018
Subjects: subject: Applied Physics (physics.app-ph)
subject: FOS: Physical sciences

description: CMUT technology was invented and has been widely researched on silicon substrates. In recent years, fabrication of CMUT on glass substrates has raised significant interests because a number of advantages it can offer. First, parasitic capacitance could be easily reduced since glass is an insulating material. Second, insulation steps required in the silicon-based CMUT fabrication process could be avoided, leading to a reduced fabrication complexity. Third, anodic bonding can be used when the substrate is borosilicate glass, which is a low-temperature bonding technique and has a high tolerance to bonding surface area and roughness in addition to the advantages of silicon wafer bonding. Moreover, glass transparency can enable novel applications beyond pulse-echo ultrasound medical imaging and enlarge the potential markets of CMUTs.

description: Young pulsars are known to exhibit large space velocities, up to $10^3$ km/s. We propose a new mechanism for the generation of these large velocities based on an asymmetric emission of neutrinos during the supernova explosion. The mechanism involves the resonant spin-flavour precession of neutrinos with a transition magnetic moment in the magnetic field of the supernova. The asymmetric emission of neutrinos is due to the distortion of the resonance surface by matter polarisation effects in the supernova magnetic field. The requisite values of the field strengths and neutrino parameters are estimated for various neutrino conversions caused by their Dirac or Majorana-type transition magnetic moments.

description: An approach is suggested defining effective sums of divergent series in the form of self-similar exponential approximants. The procedure of constructing these approximants from divergent series with arbitrary noninteger powers is developed. The basis of this construction is the self-similar approximation theory. Control functions governing the convergence of exponentially renormalized series are defined from stability and fixed-point conditions and from additional asymptotic conditions when the latter are available. The stability of the calculational procedure is checked by analyzing cascade multipliers. A number of physical examples for different statistical systems illustrate the generality and high accuracy of the approach.

A task force set up jointly by IEEE Power System Dynamic Performance Committee (PSDPC) and CIGRE had addressed the issue of stability definition and classification in power systems from a fundamental viewpoint and had closely examined the practical ramifications. The relevant report published in 2004, primarily dealt with fairly slow, electromechanical phenomena, typically present in power systems dominated by synchronous machines and their controls.

A task force set up jointly by IEEE Power System Dynamic Performance Committee (PSDPC) and CIGRE had addressed the issue of stability definition and classification in power systems from a fundamental viewpoint and had closely examined the practical ramifications. The relevant report published in 2004, primarily dealt with fairly slow, electromechanical phenomena, typically present in power systems dominated by synchronous machines and their controls. Since that time, the dynamic behavior of power systems has gradually changed due to the increasing penetration of converter interfaced generation technologies, loads, and transmission devices and has progressively become more dependent on (complex) fast-response power electronic devices, thus arising new stability concerns. In recognition of this change, a Task Force was established by IEEE PSDPC in 2016 to re-examine and extend, where appropriate, the classic definitions and classifications of the basic stability terms. This report summarizes the results of this work and presents extended definitions, characterization and classification of power system stability.

description: We develop classical balayage (sweeping) measures and subharmonic functions on the ray system $S$ with a general origin on the complex plane $\mathbb C$. This allows for a subharmonic function $v$ on $\mathbb C$ to construct also a subharmonic function on $\mathbb C$ that is harmonic outside $S$ and coincides with $v$ on $S$. We give applications to the relationship between the growth of an entire function on $S$ and the distribution of its zeros, the conditions of complete regular growth of entire and subharmonic functions on the ray system, to the problems of incompleteness of exponential systems in the spaces of holomorphic functions in nonconvex unbounded open sets narrowing near infinity. This first part of our work contains the necessary preparatory material for the construction of a new type of finite genus balayage on $S$ in the second part.

 Typus: INDONESIA. Sulawesi: s.d., Warburgs.n. (holo-: B [B100279969] image seen; iso-: FI [FI003942] image seen).
 Distribution and ecology. – Benstonea celebica is restricted to Sulawesi (Indonesia) (STONE, 1978).
 Observations. – The delimitation of this taxon remains challenging. The fruiting material deposited at Bwas apparently destroyed, but a photograph is deposited at FI. According to WARBURG’ S description (1900), B. celebica is morphologically very similar to B.pachyphylla (Merr.) Callm. & Buerki. STONE (1978) has suggested that these two entities may be conspecific, but in the absence of fruiting material we have opted to maintain them as distinct until new collections are available.

description: The magnetic behavior of a mixed Ising ferrimagnetic system on a square lattice, in which the two interpenetrating square sublattices have spins +- 1/2 and spins +-1,0, in the presence of an oscillating magnetic field has been studied with Monte Carlo techniques. The model includes nearest and next-nearest neighbor interactions, a crystal field and the oscillating external field. By studying the hysteretic response of this model to an oscillating field we found that it qualitatively reproduces the increasing of the coercive field at the compensation temperature observed in real ferrimagnets, a crucial feature for magneto-optical applications. This behavior is basically independent of the frequency of the field and the size of the system. The magnetic response of the system is related to a dynamical transition from a paramagnetic to a ferromagnetic phase and to the different temperature dependence of the relaxation times of both sublattices.

description: Trend of intensive aquaculture culture strategies negatively affect the health of aquatic organisms through suppressing immunity and increasing susceptibility to infection. Many countries have forbidden the use of certain chemotherapeutics, and also refuse to import aquaculture products treated with antibiotics and chemicals due to their residual and other side effects. Therefore, researchers have intensified efforts to exploit natural products such as herbs and plants in development of alternative dietary supplements that enhance growth performance, health and immune system of cultured organisms instead of chemotherapeutic agents. The use of herbal products belonging to different families in the management practices of aquaculture is gaining momentum, as they are safe, effective, widely available and cost effective to produce fishes free from chemicals.

description: Convection is a fundamental physical process in the fluid cores of planets because it is the primary transport mechanism for heat and chemical species and the primary energy source for planetary magnetic fields. Key properties of convection, such as the characteristic flow velocity and lengthscale, are poorly quantified in planetary cores due to their strong dependence on planetary rotation, buoyancy driving and magnetic fields, which are all difficult to model under realistic conditions. In the absence of strong magnetic fields, the core convective flows are expected to be in a regime of rapidly-rotating turbulence, which remains largely unexplored to date. Here we use a combination of numerical models designed to explore this low-viscosity regime to show that the convective lengthscale becomes independent of the viscosity and is entirely determined by the flow velocity and planetary rotation. For the Earth's core, we find that the characteristic con-vective lengthscale is approximately 30km and below this scale, motions are very weak. The 30-km cutoff scale rules out small-scale dynamo action and supports large-eddy simulations of core dynamics. Furthermore, it implies that our understanding of magnetic reversals from numerical geodynamo models does not relate to the Earth, because they require too intense flows. Our results also indicate that the liquid core of the Moon might still be in an active convective state despite the absence of a present-day dynamo.

description: This publication discusses methods for treating wastewater from the chemical industry. A chemical plant producing mineral fertilizers that discharges wastewater into the sewer system was selected for the study. Composite samples from different departments and final wastewater were collected.

Physicochemical analyzes and laboratory experiments were also carried out to determine appropriate wastewater treatment methods. Analysis of the end of the pipe revealed that the wastewater was heavily contaminated with non-biodegradable and toxic organic matter.

The main methods for treating wastewater from the chemical industry are presented.

description: The school playground provides a natural context for play observation for children of all abilities. However, play promoters interested in designing and assessing playground interventions are limited by a lack of quantitative observation tools to measure playground play sophistication for groups of children. We used Rasch analysis to evaluate the psychometric properties of a novel iPad application designed to capture observational data on the playground for children with autism spectrum disorder and/or intellectual disability. This initial investigation provides strong evidence for construct validity and moderate evidence for reliability. We suggest directions for further measure development and calibration. In conclusion, this observation tool has potential to contribute to a more nuanced understanding of playground play for children of all abilities.

 Distribution and ecology. – Benstonea copelandii is endemic to the Philippines (ranging from Luzon to Mindanao).
 Observations. – The holotype, deposited at the herbarium in Manila (PNG), was destroyed during World War II, but a fragment has been located in FI. The original collection was rather incomplete, comprising only a few drupes, which were illustrated in MARTELLI (1914: Tab. 31, Fig. 5- 7) and ST. JOHN (1969: 357, Fig. 295). We have not been able to locate the duplicate material at FI despite an extensive search. Aneotype (Elmer 15267) is therefore designated here. This collection is complete and well represented in several herbaria. Pandanus copelandii var. panchoi is considered as a synonym. It was described on the basis of a collection bearing only a single syncarp (vs 3-8 crowded, spicate syncarp in the remaining collections of Benstonea copelandii), but is considered to fall within the morphological variation of the species, even though it is rather atypical and is documented only by a single collection.

description: Ediacaran fossils are now largely known in different parts of the world. However, some countries are poorly documented on these remains of a still enigmatic life. Thus, rare fossils from the Neoproterozoic Histria Formation of central Dobrogea (Romania) have been reported. Two specimens with discoid imprints are described here in detail and assigned to the typical Ediacaran species Beltanelliformis brunsae Menner in Keller et al., 1974. This paleontological development confirms both the large geographical distribution of this species and the Ediacaran age of the Histria Formation.

description: We live in an obesogenic environment, spending a lot of time sitting neglecting physical activity. This study aims to determine the impact of a sedentary lifestyle on insulin sensitivity by comparing insulin sensitivity of healthy athletes and sedentary subjects. Twelve athletes and 12 sedentary subjects underwent a two-step hyperinsulinemic euglycemic clamp test to assess insulin sensitivity and a DEXA scan to assess body fat mass. Insulin sensitivity was significantly lower in sedentary subjects (p=0.009) and fat mass negatively correlated with insulin sensitivity (r=-0.57, p=0.005). This study shows that healthy sedentary subjects have an impaired insulin metabolism compared to trained athletes.

description: Spring rapeseed is one of the important reserves of ways to solve the creation of a solid feed base for animal husbandry in the Republic of Tyva. Recently, the farms of the republic have been cultivating rapeseed for animal feed, but there are farms that grow rapeseed for seeds. The purpose of the research: to study the phases of development and yield of the green mass of spring rapeseed of the Siberian variety in the conditions of the forest-steppe zone of the Republic of Tyva. The experience is based in the forest-steppe zone of the Piy-Khemsky district of the Republic of Tyva. The yield of green mass was 1.8 t/ha, which is 0.1 t/ha higher than the yield of green mass in Siberia. The growing season is 124 days, 27 days exceeded the characteristic given by the originator.
