description: We prove the asymptotic stability in the energy space of non-zero speed solitons for the one-dimensional Landau-Lifshitz equation with an easy-plane anisotropy. More precisely, we show that any solution corresponding to an initial datum close to a soliton with non-zero speed, is weakly convergent in the energy space as time goes to infinity, to a soliton with a possible different non-zero speed, up to the invariances of the equation. Our analysis relies on the ideas developed by Martel and Merle for the generalized Korteweg-de Vries equations. We use the Madelung transform to study the problem in the hydrodynamical framework. In this framework, we rely on the orbital stability of the solitons and the weak continuity of the flow in order to construct a limit profile. We next derive a monotonicity formula for the momentum, which gives the localization of the limit profile. Its smoothness and exponential decay then follow from a smoothing result for the localized solutions of the Schrödinger equations. Finally, we prove a Liouville type theorem, which shows that only the solitons enjoy these properties in their neighbourhoods.

description: Traumatic childhood experiences can have lifelong consequences on psychological well-being, but strong family relationships can mitigate their impact in adulthood, according to a new study by Iraqi researchers. Experiencing abuse, neglect and violence between family members or within the wider community are all associated with both psychological and social dysfunction later in life. Iraqi children, who have been subjected to political instability and mass violence for decades, are therefore at high risk. This drove Ameel AlShawi and Riyadh Lafta of Mustansiriya University in Baghdad to perform a large survey of individuals living in the Iraqi capital in 2013 in order to assess the long-term impact of their adverse childhood experiences. The researchers distributed a questionnaire across health centres and universities among people aged 18–59 to obtain information about their exposure to traumatic experiences and socio-demographic data such as health and level of education. The survey also included a series of questions designed to assess participants’ level of self-esteem. They received 1,000 responses. Overall, the vast majority of participants (nearly 83%) reported feeling confident in themselves, while more than 28% said they felt useless at times, and nearly 15% said they felt like a failure. Not surprisingly, many of those who responded to the questionnaire had experienced community violence of some sort or another. Nearly half of them had seen or heard someone being beaten up, and more than 17% had seen a family member or friend killed. Some also reported dysfunctional family scenarios. Nearly 39% had been shouted at, insulted or humiliated by a parent or other household member, for example, while 33.5% reported having been spanked, slapped, kicked or punched. But family was also a source of support for these children. The survey revealed that positive relationships within the family made people more resilient to the long-term effects of their adverse childhood experiences. Specifically, those who reported strong family bonding during childhood were far more likely to report having high levels of self-esteem later on in life. Bonding, defined as a close and emotional relationship between a child and their parents, provides a secure environment for the child, and strongly influences the quality of their future relationships.Other InformationPublished in: QScience.com Highlights, Published by Nature Research for Hamad bin Khalifa University Press (HBKU Press)

description: Each of the two STEREO spacecraft carries a SEPT Instrument which measures electrons and protons. Anisotropy observations are provided in four viewing directions. The SEP event on 7 Nov 2013 was observed by both STEREO spacecraft, which were longitudinally separated by 68° at that time. While STEREO A observed the expected characteristics of an SEP event at a well-connected position, STEREO B detected a very anisotropic bi-directional distribution of near-relativistic electrons and was situated inside a magnetic-cloud-like structure during the early phase of the event. We examine the source of the bi-directional SEP distribution at STEREO B. On the one hand this distribution could be caused by a double injection into both loop legs of the MC. On the other hand, a mirroring scenario where the incident beam is reflected in the opposite loop leg could be the reason. Furthermore, the energetic electron observations are used to probe the magnetic structure inside the magnetic cloud. We show that STEREO B was embedded in an MC-like structure ejected three days earlier. We apply a GCS model to the coronagraph observations from three viewpoints as well as the Global Magnetic Cloud model to the in situ measurements at STEREO B to determine the orientation and topology of the MC close to the Sun and at 1 AU. We also estimate the path lengths of the electrons propagating through the MC to estimate the amount of magnetic field line winding inside the structure. The relative intensity and timing of the energetic electron increases in the different SEPT telescopes at STEREO B strongly suggest that the bi-directional electron distribution is formed by SEP injections in both loop legs of the MC separately instead of by mirroring farther away beyond the STEREO orbit. Observations by the Nancay Radioheliograph of two distinct radio sources during the SEP injection further support the above scenario.

description: Mobile robots that navigate in unknown environments need to be constantly aware of the dynamic objects in their surroundings for mapping, localization, and planning. It is key to reason about moving objects in the current observation and at the same time to also update the internal model of the static world to ensure safety. In this paper, we address the problem of jointly estimating moving objects in the current 3D LiDAR scan and a local map of the environment. We use sparse 4D convolutions to extract spatio-temporal features from scan and local map and segment all 3D points into moving and non-moving ones. Additionally, we propose to fuse these predictions in a probabilistic representation of the dynamic environment using a Bayes filter. This volumetric belief models, which parts of the environment can be occupied by moving objects. Our experiments show that our approach outperforms existing moving object segmentation baselines and even generalizes to different types of LiDAR sensors. We demonstrate that our volumetric belief fusion can increase the precision and recall of moving object segmentation and even retrieve previously missed moving objects in an online mapping scenario.

By means of coincidence method, Landau level (LL) spectra of electron and hole carriers are systematically studied at different carrier densities tuned by gate voltages. When Fermi level stays in the conduction band, we observe LL crossing and anti-crossing behaviors at odd and even filling factors respectively, with a corresponding g-factor of 11.5. It remains nearly constant for varying filling factors and electron densities. On the contrary, for GaSb holes only a small Zeeman splitting is observed even at large tilt angles, indicating a g-factor of less than 3.

Infinitesimal cranking for triaxial angular-momentum-projected configuration-mixing calculation and its application to the gamma vibrational band

description: Inclusion of time-odd components into the wave function is important for reliable description of rotational motion by the angular-momentum-projection method; the cranking procedure with infinitesimal rotational frequency is an efficient way to realize it. In the present work we investigate the effect of this infinitesimal cranking for triaxially deformed nucleus, where there are three independent cranking axes. It is found that the effects of cranking about three axes on the triaxial energy spectrum are quite different and inclusion of all of them considerably modify the resultant spectrum from the one obtained without cranking. Employing the Gogny D1S force as an effective interaction, we apply the method to the calculation of the multiple gamma vibrational bands in $^{164}$Er as a typical example, where the angular-momentum-projected configuration-mixing with respect to the triaxial shape degree of freedom is performed. With this method, both the $K=0$ and $K=4$ two-phonon gamma vibrational bands are obtained with considerable anharmonicity. Reasonably good agreement, though not perfect, is obtained for both the spectrum and transition probabilities with rather small average triaxial deformation $γ\approx 9^\circ$ for the ground state rotational band. The relation to the wobbling motion at high-spin states is also briefly discussed.

Common Origin of Kinetic Scale Turbulence and the Electron Halo in the Solar Wind -- Connection to Nanoflares

description: We summarize our recent studies on the origin of solar wind kinetic scale turbulence and electron halo in the electron velocity distribution function. Increasing observations of nanoflares and microscopic type III radio bursts strongly suggest that nanoflares and accelerated electron beams are common in the corona. Based on particle-in-cell simulations, we show that both the core-halo feature and kinetic scale turbulence observed in the solar wind can be produced by the nonlinear evolution of electron two-stream instability driven by nanoflare accelerated electron beams. The energy exchange between waves and particles reaches equilibrium in the inner corona and the key features of the turbulence and velocity distribution are preserved as the solar wind escapes into interplanetary space along open magnetic field lines. Observational tests of the model and future theoretical work are discussed.

description: This report aims at solving task allocation and obstacle avoidance problems in a general context whose applications include disaster responses or packages deliveries by unmanned aerial / ground vehicles in dynamic unknown environments. More formally, we design a task allocation framework with collision avoidance capabilities in an environment populated by multiple mobile obstacles. First, we propose a decentralized auction-based algorithm for the solution of dynamic task allocation problems for spatially distributed multi-agent systems. In our approach, each member of the multi-agent team is assigned to at most one task from a set of spatially distributed tasks, while several agents can be allocated to the same task. The task assignment is dynamic since it is updated at discrete time stages (iterations) to account for the current states of the agents as the latter move towards the tasks assigned to them at the previous stage. Our proposed methods can find applications in problems of resource allocation by intelligent machines such as the delivery of packages by a fleet of unmanned or semi-autonomous aerial vehicles. In our approach, the task allocation accounts for both the cost incurred by the agents for the completion of their assigned tasks (e.g., energy or fuel consumption) and the rewards earned for their completion (which may reflect, for instance, the agents' satisfaction). We propose a Greedy Coalition Auction Algorithm (GCAA) in which the agents possess bid vectors representing their best evaluations of the task utilities. The agents propose bids, deduce an allocation based on their bid vectors and update them after each iteration. The solution estimate of the proposed task allocation algorithm converges after a finite number of iterations which cannot exceed the number of agents. We use numerical simulations to illustrate the effectiveness of the proposed task allocation algorithm (in terms of performance and computation time) in several scenarios involving multiple agents and tasks distributed over a spatial 2D domain. Secondly, we present an algorithm for local motion planning in environments populated by moving elliptical obstacles whose velocity, shape and size may change with time. We base the algorithm on a collision avoidance vector field (CAVF) that aims to steer an agent to a desired final state whose motion is described by a double integrator kinematic model. In addition to handling multiple obstacles, it is applicable in bounded environments for more realistic applications (e.g., motion planning inside a building). We also incorporate a method to deal with agents whose control input is limited so that they safely navigate around the obstacles. To showcase our approach, extensive simulations results are presented in 2D and 3D scenarios.
Correlation effects on electron-phonon coupling in semiconductors: many-body theory along thermal lines

description: A method is proposed for the inclusion of electron correlation in the calculation of the temperature dependence of band structures arising from electron-phonon coupling. It relies on an efficient exploration of the vibrational phase space along the recently introduced thermal lines. Using the $G_0W_0$ approximation, the temperature dependence of the direct gaps of diamond, silicon, lithium fluoride, magnesium oxide, and titanium dioxide is calculated. Within the proposed formalism, a single calculation at each temperature of interest is sufficient to obtain results of the same accuracy as in alternative, more expensive methods. It is shown that many-body contributions beyond semi-local density functional theory modify the electron-phonon coupling strength by almost $50$% in diamond, silicon, and titanium dioxide, but by less than $5$% in lithium flouride and magnesium oxide. The results reveal a complex picture regarding the validity of semi-local functionals for the description of electron-phonon coupling.

description: End-to-end model, especially Recurrent Neural Network Transducer (RNN-T), has achieved great success in speech recognition. However, transducer requires a great memory footprint and computing time when processing a long decoding sequence. To solve this problem, we propose a model named time-sparse transducer, which introduces a time-sparse mechanism into transducer. In this mechanism, we obtain the intermediate representations by reducing the time resolution of the hidden states. Then the weighted average algorithm is used to combine these representations into sparse hidden states followed by the decoder. All the experiments are conducted on a Mandarin dataset AISHELL-1. Compared with RNN-T, the character error rate of the time-sparse transducer is close to RNN-T and the real-time factor is 50.00% of the original. By adjusting the time resolution, the time-sparse transducer can also reduce the real-time factor to 16.54% of the original at the expense of a 4.94% loss of precision.

Campodea (Campodea) chardardi cephalonica Condé, 1984: 179, fig. 2.
Differential diagnosis from the f. typ. (Condé 1984)
From 28 to 32 antennomeres, sensillum of third antennomere in dorsal position; notal macrosetae shorter and with a few barbs; 1+1 la macrosetae on V urotergite.
Taxonomic notes
Although C. (C.) chardardi cephalonica was described from Greece with two key differences from the f. typ., the large and dorsal position of sensillum of the third antennomere and the presence of 1+1 la macrosetae on the fifth urotergite, Condé (1984) also described several specimens from Greece with the same position on the sensillum of the third antennomere but no macrosetae on the fifth urotergite. In some specimens from Greek populations (Supplementary file 2), we found a much higher variability of the fifth urotetergal macrosetae, but in all cases a dorsal sensillum on the third antennomere without macrosetae as in the type form, but with 1+1 la and 1+1 lp macrosetae.
Habitat and distribution
Soil-dwelling species spreading from the Basin of Paris to the Central Massif of France (Condé 1947d; 1947h; Pagés 1951; Bareth & Condé 1998). The records of this species from the southwestern Balkan Peninsula and Crete Island should be attributed to C. chardardi cephalonica (Condé 1984).

description: Context. Pisces A & Pisces B are the only two galaxies found via optical imaging and spectroscopy out of 22 HI clouds identified in the GALFAHI survey as dwarf galaxy candidates. Aims. Derive the HI content and kinematics of Pisces A & B. Methods. Aperture synthesis HI observations using the seven dish Karoo Array Telescope (KAT-7), which is a pathfinder instrument for MeerKAT, the South African precursor to the mid-frequency Square Kilometre Array (SKA-MID). Results. The small rotation velocities detected of ~5 km/sec and ~10 km/sec in Pisces A & B respectively, and their HI content show that they are really dwarf irregular galaxies (dIrr). Despite that small rotation component, it is more the random motions ~9-11 km/sec that provide most of the gravitational support, especially in the outer parts. The study of their kinematics, especially the strong gradients of random motions, suggest that those two dwarf galaxies are not yet in equilibrium. Conclusions. These HI rich galaxies may be indicative of a large population of dwarfs at the limit of detectability. However, such gas-rich dwarf galaxies will most likely never be within the virial radius of MW-type galaxies and become sub-halo candidates. Systems such as Pisces A & B are more likely to be found at a few Mpc.s from MW-type galaxies.

description: 1. Melatonin is an indole hormone that, among its myriad biological functions, regulates circadian and seasonal rhythms in animals. The ASMT gene plays an essential role in melatonin synthesis. However, in chickens, little is known about the regulatory elements governing its transcription. 2. The following study identified the transcription start site of the chicken ASMT gene by 5’-RACE. Then, the proximal minimal promoter was identified using a series of 5′ truncations of the ASMT promoter (e.g. −3502/+17, −2698/+17, −2003/+17, −1378/+17, and −254/+17). Site-directed mutagenesis, overexpression, and electrophoretic mobility shift assay (EMSA) were applied to show that the transcription factor Oct-1 binds to the promoter region of ASMT. 3. The translation start site was located 19 bp upstream from the translational start site. The luciferase reporter assay confirmed that the core promoter of chicken ASMT gene was in the −254/+17 region. Using site-directed mutagenesis, overexpression, and EMSA, Oct-1 bound the promoter of ASMT. 4. Overall, Oct1 plays an important role in the transcriptional regulation of chicken ASMT gene.

description: In diesem Beitrag wird eine Schulbuchanalyse, als Teil meines Promotionsprojektes, zum Thema Umgang mit Variablen bei der Einführung von Termen und Gleichungen vorgestellt. Die Grundlage der Analyse bildet das Schulbuch Schnittpunkt 7 für Realschulen von 2006 in der Auflage für Nordrhein-Westfalen. Dabei wird auch der begleitende Serviceband, welcher über die Schwerpunkte und Intentionen der Schulbuchautoren Auskunft gibt, in die Analyse mit einbezogen. Die zugrundeliegenden Fragestellungen lauten: Wie wird der Begriffe Variable eingeführt und wofür stehen die verwendeten Buchstaben auf den Schulbuchseiten? Was sind die zugrundeliegenden Objekte für die Lernenden? Und welche impliziten oder expliziten Begründungen gibt es auf den Seiten? Die Antworten auf diese Fragen lassen Rückschlüsse auf die Auffassung von Algebra zu, welcher die Lernenden auf Grundlage dieses Schulbuches erwerben. Um die Einführung und die Behandlung von Variablen richtig deuten zu können, ist es wesentlich den Stand der Lernenden zu berücksichtigen, welchen sie auf Grundlage der Schulbücher der Klassen fünf und sechs erworben haben.

description: We investigate the Casimir stress on a topological insulator (TI) between two metallic plates. The TI is assumed to be joined to one of the plates and its surface in front of the other is covered by a thin magnetic layer, which turns the TI into a full insulator. We also analyze the limit where one of the plates is sent to infinity yielding the Casimir stress between a conducting plate and a TI. To this end we employ a local approach in terms of the stress-energy tensor of the system, its vacuum expectation value being subsequently evaluated in terms of the appropriate Green's function. Finally, the construction of the renormalised vacuum stress-energy tensor in the region between the plates yields the Casimir stress. Numerical results are also presented.

description: 1. This paper details the establishment of a diagnostic system based on the real-time reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for the rapid, simple and sensitive detection of genotype VII of Newcastle disease virus (NDV) directly from field samples. One specific set of six primers were designed which targeted the fusion protein gene of G-VII viruses. The target gene can be amplified and the results recorded within 40 min. 2. The merit of this technique was the feasibility of reading results either by examining turbidity by the naked eye or via the amplification curve generated by real-time PCR. This study tested the sensitivity and specificity of this system against NDV-G-VII and other avian viruses. The real-time RT-LAMP has been found to be more sensitive than real-time RT-PCR. Moreover, 24 out of 35 suspected field samples were positive for genotype VII by real-time RT-LAMP within 30 min in comparison to the real-time RT-PCR for detection of universal NDV. 3. Accordingly, real-time RT-LAMP revealed higher sensitivity than real-time RT-PCR and had specificity only for the NDV-G-VII genotype. Additionally, this system was more rapid and had lower cost than real-time RT-PCR. Based on the results, the RT-LAMP-based assay is a useful tool for the rapid and sensitive diagnosis of NDV-G-VII infection.

description: We investigate the performance of an underdamped stochastic heat engine for a time-dependent harmonic oscillator. We analytically determine the optimal protocol that maximizes the efficiency at fixed power. The maximum efficiency reduces to the Curzon-Ahlborn formula at maximum power and the Carnot formula at zero power. We further establish that the efficiency at maximum power is universally given by the Curzon-Ahlborn efficiency in the weakly damped regime. Finally, we show that even small deviations from operation at maximum power may result in a significantly increased efficiency.

description: 1. This study measured six reproduction traits in a Sichuan white goose population (209 individuals), including fertility, qualified egg rate, plasma concentrations of progesterone (P), follicle-stimulating hormone (FSH), prolactin (PRL) and oestrogen (E2). 2. Whole-genome resequencing data from the same goose population (209 individuals) were used in a genome-wide association study (GWAS) utilising a mixed linear model to investigate the genes and genetic markers associated with reproduction traits. The frequency of the selected SNPs and haplotypes were determined using the Matrix-Assisted Laser Desorption Ionisation Time-Of-Flight Mass Spectrometry (MALDI-TOF MS) method. 3. In total, 42 SNPs significantly associated with these traits were identified. A haplotype block was constructed based on five SNPs that were significantly associated with qualified egg rate, with individuals having the haplotype CCTTAAGGAA having the lowest qualified egg rate. 4. In conclusion, these results provided potential markers for marker-assisted selection to improve goose reproductive performance and a basis for elucidating the genetics of goose reproduction.
