description: We propose a new observable designed to probe CP-violating coupling of the Higgs boson to W bosons using associated Higgs production. We define an asymmetry that measures the number of leptons from W decays relative to the plane defined by the beam line and the Higgs boson momentum. The orientation of that plane is determined by the direction of fermions in the initial state, so that in a proton-proton collider it requires rapidity cuts that preferentially select quarks over antiquarks.

description: Objective:

Tonic-clonic activity (TCA) at onset complicates 3% to 21% of cases of subarachnoid hemorrhage (SAH). The impact of onset TCA on in-hospital complications, including seizures, remains unclear. One study associated onset TCA with poor clinical outcome at 6 weeks after SAH, but to our knowledge no other studies have confirmed this relationship. This study aims to assess the impact of onset TCA on in-hospital complications, poor functional outcome, mortality, and epilepsy at 3 months.

Methods:

Analysis of a prospective study cohort of 1479 SAH patients admitted to Columbia University Medical Center between 1996 and 2012. TCA within 6 hours of hemorrhage onset was identified based on accounts of emergency care providers or family witnesses.

Results:

TCA at onset was described in 170 patients (11%). Patients with onset TCA were younger (P = 0.002), presented more often with poor clinical grade (55% vs. 26%, P<0.001) and had larger amounts of cisternal, intraventricular, and intracerebral blood than those without onset TCA (all, P<0.001). After adjusting for known confounders, onset TCA was significantly associated with in-hospital seizures (OR 3.80, 95%-CI: 2.43–5.96, P<0.001), in-hospital pneumonia (OR 1.56, 95%-CI: 1.06–2.31, p = 0.02), and delayed cerebral ischemia (OR 1.77, 95%-CI: 1.21–2.58, P = 0.003). At 3 months, however, onset TCA was not associated with poor functional outcome, mortality, and epilepsy after adjusting for age, admission clinical grade, and cisternal blood volume.

Conclusions:

Onset TCA is not a rare event as it complicates 11% of cases of SAH. New and clinically relevant findings are the association of onset TCA with in-hospital seizures, pneumonia and delayed cerebral ischemia. Despite the increased risk of in-hospital complications, onset TCA is not associated with disability, mortality, and epilepsy at 3 months.

Die Überlebenden sind nach wie vor mit Aufräumarbeiten beschäftigt, vor allem aber mit dem verzweifelten Bemühen, ihre Grundbedürfnisse wie Trinkwasser, Essen und medizinische Hilfe zu sichern. Todbringende Stürme hat es in der Region schon seit Menschengedenken gegeben, doch das Risiko extremer Naturereignisse, das durch den Klimawandel heraufbeschworen wird, wird immer größer. Die derzeitige humanitäre Krise wird zudem noch von der weltweit steigenden Nachfrage nach Lebensmittel vergrößert, die auch in Bangladesch zu einem rasanten Preisanstieg der Grundnahrungsmittel geführt hat. Der Klimawandel birgt, wie in anderen Teilen der Welt, für eine immer größer werdende Bevölkerungsgruppe die reale Gefahr des Hungertodes in sich.

description: Independent research groups reported that DING protein homologues isolated from bacterial, plant and human cells demonstrate the anti-HIV-1 activity. This might indicate that diverse organisms utilize a DING-mediated broad-range protective innate immunity response to pathogen invasion, and that this mechanism is effective also against HIV-1. We performed structural analyses and evaluated the anti-HIV-1 activity for four DING protein homologues isolated from different species. Our data show that bacterial PfluDING, plant p38SJ (pDING), human phosphate binding protein (HPBP) and human extracellular DING from CD4 T cells (X-DING-CD4) share high degrees of structure and sequence homology. According to earlier reports on the anti-HIV-1 activity of pDING and X-DING-CD4, other members of this protein family from bacteria and humans were able to block transcription of HIV-1 and replication of virus in cell based assays. The efficacy studies for DING-mediated HIV-1 LTR and HIV-1 replication blocking activity showed that the LTR transcription inhibitory concentration 50 (IC50) values ranged from 0.052–0.449 ng/ml; and the HIV-1 replication IC50 values ranged from 0.075–0.311 ng/ml. Treatment of cells with DING protein alters the interaction between p65-NF-κB and HIV-1 LTR. Our data suggest that DING proteins may be part of an innate immunity defense against pathogen invasion; the conserved structure and activity makes them appealing candidates for development of a novel therapeutics targeting HIV-1 transcription.

description: Hybrid AMX3 perovskites (A=Cs, CH3NH3; M=Sn, Pb; X=halide) have revolutionized the scenario of emerging photovoltaic technologies. Introduced in 2009 by Kojima et al., a rapid evolution very recently led to 15% efficient solar cells. CH3NH3PbI3 has so far dominated the field, while the similar CH3NH3SnI3 has not been explored for photovoltaic applications, despite the reduced band-gap. Replacement of Pb by the more environment-friendly Sn would facilitate the large uptake of perovskite-based photovoltaics. Despite the extremely fast progress, the materials electronic properties which are key to the photovoltaic performance are relatively little understood. Here we develop an effective GW method incorporating spin-orbit coupling which allows us to accurately model the electronic, optical and transport properties of CH3NH3SnI3 and CH3NH3PbI3, opening the way to new materials design. The different CH3NH3SnI3 and CH3NH3PbI3 properties are discussed in light of their exploitation for solar cells, and found to be entirely due to relativistic effects.

description: In Bulta, einem kleinen Dorf 25 km südlich der bangladeschischen Hauptstadt Dhaka, startet in diesem Jahr das erste Projekt weltweit, welches durch Recycling von organischen Abfällen vom internationalen Emissionshandel profitiert. In der Anlage in Bulta werden ab diesem Jahr täglich 130 Tonnen organische Abfälle in Düngemittel weiterverarbeitet. Waste Concern, die Organisation, die hinter dieser Idee steckt, plant hier in absehbarer Zeit bis zu 700 Tonnen Müll täglich zu verwerten. Dafür erhält Waste Concern so genannte carbon credits: Da das Recycling organischer Abfälle den Ausstoß von Treibhausgasen verringert, kann diese Einsparung im Rahmen des Emissionshandels gewinnbringend verkauft werden. Rund ein Drittel der Einnahmen aus dem Projekt stammen aus dem Erlös der carbon credits, der Rest aus dem Verkauf des Düngers. Die Idee aus Bangladesch ist eine Erfolgsgeschichte: Das Recycling-Modell vereint Umwelt- und Klimaschutz, nachhaltige Entwicklung sowie Armutsbekämpfung und wirft gleichzeitig Gewinn ab. Waste Concern gilt längst als best-practice Beispiel und wird in Dutzenden Städten weltweit nachgeahmt.

description: Neurogenin3+ (Ngn3+) progenitor cells in the developing pancreas give rise to five endocrine cell types secreting insulin, glucagon, somatostatin, pancreatic polypeptide and ghrelin. Gastrin is a hormone produced primarily by G-cells in the stomach, where it functions to stimulate acid secretion by gastric parietal cells. Gastrin is expressed in the embryonic pancreas and is common in islet cell tumors, but the lineage and regulators of pancreatic gastrin+ cells are not known. We report that gastrin is abundantly expressed in the embryonic pancreas and disappears soon after birth. Some gastrin+ cells in the developing pancreas co-express glucagon, ghrelin or pancreatic polypeptide, but many gastrin+ cells do not express any other islet hormone. Pancreatic gastrin+ cells express the transcription factors Nkx6.1, Nkx2.2 and low levels of Pdx1, and derive from Ngn3+ endocrine progenitor cells as shown by genetic lineage tracing. Using mice deficient for key transcription factors we show that gastrin expression depends on Ngn3, Nkx2.2, NeuroD1 and Arx, but not Pax4 or Pax6. Finally, gastrin expression is induced upon differentiation of human embryonic stem cells to pancreatic endocrine cells expressing insulin. Thus, gastrin+ cells are a distinct endocrine cell type in the pancreas and an alternative fate of Ngn3+ cells.

description: We study the temperature dependence of the spin Hall magnetoresistance (SMR) in yttrium iron garnet/platinum hybrid structures via magnetization orientation dependent magnetoresistance measurements. Our experiments show a decrease of the SMR magnitude with decreasing temperature. Using the sensitivity of the SMR to the spin transport properties of the normal metal, we interpret our data in terms of a decrease of the spin Hall angle in platinum from 0.11 at room temperature to 0.075 at 10K, while the spin diffusion length and the spin mixing conductance of the ferrimagnetic insulator/normal metal interface remain almost constant.

description: Certain genes exhibit notable diversity in their expression patterns both within and between species. One such gene is the vasopressin receptor 1a gene (Avpr1a), which exhibits striking differences in neural expression patterns that are responsible for mediating differences in vasopressin-mediated social behaviors. The genomic mechanisms that contribute to these remarkable differences in expression are not well understood. Previous work has suggested that both the proximal 5′ flanking region and a polymorphic microsatellite element within that region of the vole Avpr1a gene are associated with variation in V1a receptor (V1aR) distribution and behavior, but neither has been causally linked. Using homologous recombination in mice, we reveal the modest contribution of proximal 5′ flanking sequences to species differences in V1aR distribution, and confirm that variation in V1aR distribution impacts stress-coping in the forced swim test. We also demonstrate that the vole Avpr1a microsatellite structure contributes to Avpr1a expression in the amygdala, thalamus, and hippocampus, mirroring a subset of the inter- and intra-species differences observed in central V1aR patterns in voles. This is the first direct evidence that polymorphic microsatellite elements near behaviorally relevant genes can contribute to diversity in brain gene expression profiles, providing a mechanism for generating behavioral diversity both at the individual and species level. However, our results suggest that many features of species-specific expression patterns are mediated by elements outside of the immediate 5′ flanking region of the gene.

description: Combining two solutions of different composition releases the Gibbs free energy of mixing. By using engineered processes to control the mixing, chemical energy stored in salinity gradients can be harnessed for useful work. In this critical review, we present an overview of the current progress in salinity gradient power generation, discuss the prospects and challenges of the foremost technologies — pressure retarded osmosis (PRO), reverse electrodialysis (RED), and capacitive mixing (CapMix) and provide perspectives on the outlook of salinity gradient power generation. Momentous strides have been made in technical development of salinity gradient technologies and field demonstrations with natural and anthropogenic salinity gradients (for example, seawater–river water and desalination brine-wastewater, respectively), but fouling persists to be a pivotal operational challenge that can significantly ebb away cost-competitiveness. Natural hypersaline sources (e.g., hypersaline lakes and salt domes) can achieve greater concentration difference and, thus, offer opportunities to overcome some of the limitations inherent to seawater–river water. Technological advances needed to fully exploit the larger salinity gradients are identified. While seawater desalination brine is a seemingly attractive high salinity anthropogenic stream that is otherwise wasted, actual feasibility hinges on the appropriate pairing with a suitable low salinity stream. Engineered solutions are foulant-free and can be thermally regenerative for application in low-temperature heat utilization. Alternatively, PRO, RED, and CapMix can be coupled with their analog separation process (reverse osmosis, electrodialysis, and capacitive deionization, respectively) in salinity gradient flow batteries for energy storage in chemical potential of the engineered solutions. Rigorous techno-economic assessments can more clearly identify the prospects of low-grade heat conversion and large-scale energy storage. While research attention is squarely focused on efficiency and power improvements, efforts to mitigate fouling and lower membrane and electrode cost will be equally important to reduce levelized cost of salinity gradient energy production and, thus, boost PRO, RED, and CapMix power generation to be competitive with other renewable technologies. Cognizance of the recent key developments and technical progress on the different technological fronts can help steer the strategic advancement of salinity gradient as a sustainable energy source.

Resistance of High Tension Porcelain Insulators
Creators: name: Morgan, Stanley Chapin
Publisher: name: California Institute of Technology
Year: 1928
Subjects: Electrical Engineering

description: High tension insulators are generally built of several porcelain discs in series, the discs being connected by galvanized steel hardware.  When alternating voltage is impressed across such a string the voltage is not distributed symmetrically because the charging current is not the same through the string.  There is capacitance from each connector to the next, from each connector to the ground and to the line wire, as well as capacitance from one connector to one which is not adjacent.  If the voltage impressed is direct and all the units or discs are exactly alike, then such an air insulator string would have across each unit the same value of voltage.  A certain leakage current flows through each insulator, and the d.c. voltage across each unit will be the leakage current multiplied by the resistance of each unit.

In the transmission of high-voltage direct current, such as the Thury system found in Europe, high-tension porcelain insulators can be used to insulate the line from the ground.  Such insulators are exposed to changing weather conditions of humidity and temperature.  Also, these insulators on account of being subjected to mechanical stresses, electrical stresses, and repeated temperature cycles, depreciate in resistance, become faulty, and unless detected may interfere with the operation of the transmission system.  If the resistance of the insultors forming the string, and the effect produced on the resistance by temperature, humidity, etcetera, are known then it is possible to predict to a certain degree of approximation what service the insulators can give.  Besides determining the condition of such insulators, a knowledge of the resistance would give a basis for comparing different types of insulators, and likewise would furnish a means for arriving at the voltage distribution of different makes and types and the uniformity with which a given type could be expected to run.

In the investigation carried out, the results of which are tabulated below, particular attention was given to the determination of the surface and interior resistance, and the effect of change of temperature and humidity on the electrical resistance of various types and makes of high-tension porcelain insulators.  The humidity effect is not an internal one, but manifests itself by changing the surface of the insulator so that a greater freedom is given to the flow of current over the surface between the cap and the pin of the insulator.

description: The damping coefficients for the alkali atoms are determined very accurately by taking into account the optical properties of the atoms and three distinct types of trapping materials such as Au (metal), Si (semi-conductor) and vitreous SiO2 (dielectric). Dynamic dipole polarizabilities are calculated precisely for the alkali atoms that reproduce the damping coefficients in the perfect conducting medium within 0.2% accuracy. Upon the consideration of the available optical data of the above wall materials, the damping coefficients are found to be substantially different than those of the ideal conductor. We also evaluated dispersion coefficients for the alkali dimers and compared them with the previously reported values. These coefficients are fitted into a ready-to-use functional form to aid the experimentalists the interaction potentials only with the knowledge of distances.

Our approach is motivated by techniques developed by Warren and others during the study of cycle-free partial orders. We give several new families of previously unknown countably infinite locally-2-arc-transitive graphs, each family containing continuum many members. These examples are obtained by gluing together copies of incidence graphs of semilinear spaces, satisfying a certain symmetry property, in a tree-like way. In one case we show how the classification problem for that family relates to the problem of determining a certain family of highly arc-transitive digraphs. Numerous illustrative examples are given.

A Tertiary Mammalian Fauna from the Mint Canyon Formation, Southern California

description: The Mint Canyon beds, typically exposed in Mint Canyon seven miles northeast of Saugus, California, were described by Dr. W. S. W. Kew in Bulletin 753 (1924) of the United States Geological Survey.  In 1919 during the course of geologic mapping of this region by Dr. Kew, fossil vertebrate remains were found at several localities.  The types represented in the collection were recorded in Kew’s paper in a provisional list submitted by Dr. Chester Stock.  However, no detailed study was made of this material.  Further mammalian remains have been recently secured from the Mint Canyon formation by Mr. Thomas Clements during geologic study of the Tejon Quadrangle.

In view of the geologic position of the Mint Canyon beds, intercalated in a series of marine formations of the Pacific Coast marine province, the terrestrial fauna secured from these deposits is not only important in establishing the age of the Mint Canyon but also furnishes a basis for comparing the Tertiary record of this region with that of the Great Basin to the east.  Opportunities to correlate the Tertiary marine record with the terrestrial record of the Great Basin and of the Great Plains on the basis of land vertebrates are of infrequent occurrence and warrant in the present instance a careful survey of the Mint Canyon fauna.

Dadurch wird die Wasserspeicherungskapazität des höchsten Gebirges der Welt empfindlich beeinträchtigt. Außerdem steigt das Risiko von Gletschersee-Ausbrüchen (Glacial Lake Outburst Floods, GLOFs), die ganze Regionen in Mitleidenschaft ziehen könnte. Thomas Döhne sprach mit Dr. Mats Eriksson, Gletscherforscher und stellvertretender Direktor von ICIMOD, in Kathmandu über die Auswirkungen von Erderwärmung und Klimawandels im Himalayaraum. Hier einige Auszüge aus dem Gespräch.

description: We investigate the chiral structure of local vector and axial-vector tetraquark currents, and study their chiral transformation properties. We consider the charge-conjugation parity and classify all the isovector vector and axial-vector local tetraquark currents of quantum numbers I(G)J(PC)=1(-)1(-+), I(G)J(PC)=1(+)1(--), I(G)J(PC)=1(-)1(++) and I(G)J(PC)=1(+)1(+-). We find that there is a one to one correspondence among them. Using these currents, we perform QCD sum rule analyses. Our results suggest that there is a missing b1 state having I(G)J(PC)=1(+)1(+-) and a mass around 1.47-1.66 GeV.

description: Spectral properties of bounded linear operators play a crucial role in several areas of mathematics and physics. For each self-adjoint, trace-class operator $O$ we define a set $Λ_n\subset \mathbb{R}$, and we show that it converges to the spectrum of $O$ in the Hausdorff metric under mild conditions. Our set $Λ_n$ only depends on the first $n$ moments of $O$. We show that it can be effectively calculated for physically relevant operators, and it approximates the spectrum well.
 We prove that using the above method we can converge to the minimal and maximal eigenvalues with super-exponential speed.
 We also construct monotone increasing lower bounds $q_n$ for the minimal eigenvalue (or decreasing upper bounds for the maximal eigenvalue). This sequence only depends on the moments of $O$ and a concrete upper estimate of its $1$-norm; we also demonstrate that $q_n$ can be effectively calculated for a large class of physically relevant operators. This rigorous lower bound $q_n$ tends to the minimal eigenvalue with super-exponential speed provided that $O$ is not positive semidefinite. As a by-product, we obtain computable upper bounds for the $1$-norm of $O$, too.
description: 26 pages, 3 figures, 2 tables. We made significant modifications, most importantly we added a new section about approximating the spectrum. We changed the title and updated the Introduction section accordingly, too

Solution of the alpha-potential mystery in the gamma-process and its impact on the Nd/Sm ratio in meteorites

description: The 146Sm/144Sm ratio in the early solar system has been constrained by Nd/Sm isotope ratios in meteoritic material. Predictions of 146Sm and 144Sm production in the gamma-process in massive stars are at odds with these constraints and this is partly due to deficiences in the prediction of the reaction rates involved. The production ratio depends almost exclusively on the (gamma,n)/(gamma,alpha) branching at 148Gd. A measurement of 144Sm(alpha,gamma)148Gd at low energy had discovered considerable discrepancies between cross section predictions and the data. Although this reaction cross section mainly depends on the optical alpha+nucleus potential, no global optical potential has yet been found which can consistently describe the results of this and similar alpha-induced reactions at the low energies encountered in astrophysical environments. The untypically large deviation in 144Sm(alpha,gamma) and the unusual energy dependence can be explained, however, by low-energy Coulomb excitation which is competing with compound nucleus formation at very low energies. Considering this additional reaction channel, the cross sections can be described with the usual optical potential variations, compatible with findings for (n,alpha) reactions in this mass range. Low-energy (alpha,gamma) and (alpha,n) data on other nuclei can also be consistently explained in this way. Since Coulomb excitation does not affect alpha-emission, the 148Gd(gamma,alpha) rate is much higher than previously assumed. This leads to small 146Sm/144Sm stellar production ratios, in even more pronounced conflict with the meteorite data.

description: Thermoelectric material provides a high hope for converting harmful and useless heat into useful energy, electricity. It can also be used as solid state Peltier coolers in integrated circuits, an outstanding challenge for electronic engineers. The desire for a high efficient thermoelectric material has never been so keen. Although many works have been done, we are still far from having a recipe for thermoelectric materials. Nano-structuring provides an effective way to increase figure of merit (ZT) by reducing the thermal conductivity without affecting electronic property.1 Here, we propose a novel nanoscale three-dimensional (3D) Si phononic crystal (PnC) with spherical pores, which can reduce the thermal conductivity of bulk Si by a factor up to 10,000 times at room temperature. The extreme-low thermal conductivity could lead to a larger value of ZT than unity. The thermal conductivity changes little when temperature increases from room temperature to 1100 K. The phonon participation ratio spectra show there are more phonon localizations as the porosity of PnC increases.

description: In this paper, we prove new multilinear Strichartz estimates, which are obtained by using techniques of Bourgain. These estimates lead to new critical well-posedness results for the nonlinear Schrödinger equation on irrational tori in two and three dimensions with small initial data.
