description: Interactions between silica surfaces across isopropanol solutions are measured with colloidal probe technique based on atomic force microscope. In particular, the influence of 1:1 electrolytes on the interactions between silica particles is investigated. A plethora of different forces are found in these systems. Namely, van der Waals, double-layer, attractive non-DLVO, repulsive solvation, and damped oscillatory interactions are observed. The measured decay length of the double-layer repulsion is substantially larger than Debye lengths calculated from nominal salt concentrations. These deviations are caused by pronounced ion pairing in alcohol solutions. At separation below 10 nm, additional attractive and repulsive non-DLVO forces are observed. The former are possibly caused by charge heterogeneities induced by strong ion adsorption, whereas the latter originate from structuring of isopropanol molecules close to the surface. Finally, at increased concentrations the transition from monotonic to damped oscillatory interactions is uncovered.

description: We model the observed size and brightness of the VLBA radio core of the jet in Cygnus X-1 to derive an expression for the jet power as a function of basic jet parameters. We apply this expression to recent constraints on the jet power from observations of a large scale shocked shell around the source by Gallo et al. 2005, which leads us to a set of alternative conclusions: either (a) the jet contains large amounts of protons: more than 2000 protons per radio emitting electron, (b) it has a very low radio volume filling factor of f < 3x10^(-5), (c) the steady, radio emitting VLBA jet is not the source of the kinetic energy powering the ISM shell, or (d) its asymptotic behavior differs fundamentally from a broad set of plausible analytic jet models.

description: We investigate the ground-state properties of the spin-half $J_1{-}J_2$ Heisenberg chain with a next-nearest-neighbor spin-Peierls dimerization using conformal field theory and Lanczos exact diagonalizations. In agreement with the results of a recent bosonization analysis by Sarkar and Sen, we find that for small frustration ($J_2/J_1$) the system is in a Luttinger spin-fluid phase, with gapless excitations, and a finite spin-wave velocity. In the regime of strong frustration the ground state is spontaneously dimerized and the bond alternation reduces the triplet gap, leading to a slight enhancement of the critical point separating the Luttinger phase from the gapped one. An accurate determination of the phase boundary is obtained numerically from the study of the excitation spectrum.

description: The rootstock ‘Myrobalan 29C’ (Prunus cerasifera Ehrh.) is one of the widely used rootstocks for production of plum and apricot planting material. In May, 2020, on the adaxial and abaxial leaf surfaces and young stems of ‘Myrobalan 29C’ rootstocks, typical symptoms of powdery mildew - white powdery colonies with white superficial mycelium and conidia were observed. Later on chasmothecia appeared in some injured leaf tissues. The microscope findings visualized conidia formed in true chains on erect conidiophores which were ellipsoid, hyaline and measured 24.6 to 33.6 x 10.8 to 20.8 µm (average 29.6 x 15.8 µm) and globose chasmothecia with appendages arising from the upper half of the fruiting bodies. Usually, appendages were in length one to four times long towards the chasmothecial diameter and had two to four dichotomous branches. A single ascus, observed in a chasmothecium, was broadly ellipsoid-ovoid contained six to eight ascospores. The shape of the ascospores was ellipsoid-ovoid too. Pathogenicity tests were carried out by inoculation of healthy ‘Myrobalan 29C’, apricot (P. armeniaca L.) and cherry (P. avium L.) plants. Disease signs on all of the inoculated experimental species appeared as white powdery coating very similar to the powdery coating on natural infected ‘Myrobalan 29C’. Based on the morphological characteristics of the conidia, chasmothecia and results of the pathogenicity tests, the causal agent of the symptoms observed was presumed to belong to Podosphaera sp. (Ascomycetes). To the best of our knowledge, previously no detailed characterization of Podosphaera sp. in P. creasifera has been reported in Bulgaria

description: Modern HENP experiments such as CMS and Atlas involve as many as 2000 collaborators around the world. Collaborations this large will be unable to meet often enough to support working closely together. Many of the tools currently available for collaboration focus on heavy-weight applications such as videoconferencing tools. While these are important, there is a more basic need for tools that support connecting physicists to work together on an ad hoc or continuous basis. Tools that support the day-to-day connectivity and underlying needs of a group of collaborators are important for providing light-weight, non-intrusive, and flexible ways to work collaboratively. Some example tools include messaging, file-sharing, and shared plot viewers. An important component of the environment is a scalable underlying communication framework. In this paper we will describe our current progress on building a dynamic and ad hoc collaboration environment and our vision for its evolution into a HENP collaboration environment.

description: One way to analyze the impact of commodity price shocks on monetary policy is to think about short-term interest rates set by Fed according to the Taylor rule. Taylor (1993) suggested a policy reaction function for moderating short-term interest rates to achieve the two-fold goals of stabilizing economic growth in the short-term and inflation in the long-term. One important question is why monetary policy makers focus on core inflation instead of headline inflation. Therefore, the main goal of this research article is to study the pattern of monetary policy responses to commodity price shocks derived from an impulse response function (IRF). To do this, we first estimate two individual Taylor rules based on core and headline consumer price index (CPI) inflation by using real-time data of the US economy for the Greenspan years from 1987 to 2006 and predict the residuals. Then, we estimate two regressions for core and headline CPI inflation as our two individual dependent variables against some independent variables including commodity price shocks, and the Taylor rule residuals. At the end, we predict the monetary policy responses to commodity price shocks by using IRF analysis in multivariate systems of a vector autoregression (VAR) model.

description: The 2009 WIC Program policy changes were designed to improve breastfeeding rates and health outcomes of WIC participants. Existing research in this area found that participants shifted towards healthier eating behavior after the changes in WIC food packages. However, little is known about the effect of these changes on the rural participants. Using the data from the National Food and Nutrition Survey (NATFAN), we examined the effects of the revised WIC food packages on breastfeeding among WIC participants in rural and non-rural areas, and food deserts. Our findings show that WIC participants were more likely to choose fully breastfeeding package after the revisions in WIC. Furthermore, we found that participants who were Hispanic, with lower degrees of education, living in the Southern region of the United States were less likely to choose full breastfeeding package. Overall, a greater proportion of rural participants utilized full breastfeeding package than non-rural participants.

description: We study the rectification of near-field radiative heat transfer between two InSb nano-particles due to the presence of non-reciprocal surface modes in a nearby InSb sample when an external magnetic field is applied and its dependence on the magnetic field strength. We reveal the spin-spin coupling mechanism of the localized particle resonances and the surface mode resonances which is substantiated by the directional heat flux in the given setup. We discuss further the interplay of the frequency shift, the propagation length, and local density of states on the strength and directionality of the rectification as well as the non-reciprocal heating effect of the nanoparticles.

In our experiment atoms in a $^{87}$Rb condensate are exposed to laser light which is tuned close to the transition frequency to an excited molecular state. By controlling the power and detuning of the laser beam we can change the atomic scattering length over a wide range. In view of laser-driven atomic losses we use Bragg spectroscopy as a fast method to measure the scattering length of the atoms.

description: The semi-constrained NMSSM (scNMSSM), or NMSSM with non-universal Higgs masses, can naturally predict a light dark matter under current constraints including Higgs data, sparticle-mass bounds, dark matter searches, and muon g-2, etc. In this work, we take this scenario of scNMSSM as an example to study the funnel-annihilation mechanisms of light dark matter ($1\!\thicksim\!62$ GeV) and the invisible Higgs decay. In this scenario we found that: (i) There can be four funnel-annihilation mechanisms for the LSP $\tildeχ^0_1$, which are the $h_2$, $Z$, $h_1$ and $a_1$ funnel. (ii) For the $h_1$ and $a_1$ funnel with right relic density, the $\tildeχ^0_1$ mass is lighter than 12 GeV, and the invisible Higgs decay can be $2\%$ at most. (iii) For the $h_2$ and $Z$ funnel with right relic density, the invisible Higgs decay can be about $0.4\%$ and $1\%$ respectively at most. (iv) If the invisible Higgs decay was discovered at the HL-LHC, the four funnel-annihilation mechanisms of light dark matter may be all excluded with $\tildeχ^0_1$ as the only dark matter source. Four benchmark points, one for each mechanism, are proposed for future checking with updated experimental results.

description: Both neutrinoless double beta decay and leptogenesis require neutrinos to be Majorana fermions. A relation between these two phenomena can be derived once the mechanism of neutrino mass generation is specified. We first derive the constraints on the Majorana phases by minimising the effective neutrino mass in neutrinoless double beta decay with respect to the smallest mass among the light neutrinos. Given these phases, we derive a lower bound on $M_{1}$ (the mass of the lightest of the heavy neutrinos) in the framework of Type-I seesaw mechanism, subject to the constraint that the CP asymmetry required for adequate leptogenesis is larger than $10^{-8}$. We find that $M_{1} \geq 10^{10}\,(10^{9})$ GeV for the case of Normal (Inverted) hierarchy. We extend our analysis to the case when one of the heavy neutrinos decouples (two right handed neutrino models). In this case we find $M_{1} \geq 10^{10}\,(10^{11})$ GeV for the case of Normal (Inverted) hierarchy.

description: Quality-Diversity (QD) algorithms, and MAP-Elites (ME) in particular, have proven very useful for a broad range of applications including enabling real robots to recover quickly from joint damage, solving strongly deceptive maze tasks or evolving robot morphologies to discover new gaits. However, present implementations of MAP-Elites and other QD algorithms seem to be limited to low-dimensional controllers with far fewer parameters than modern deep neural network models. In this paper, we propose to leverage the efficiency of Evolution Strategies (ES) to scale MAP-Elites to high-dimensional controllers parameterized by large neural networks. We design and evaluate a new hybrid algorithm called MAP-Elites with Evolution Strategies (ME-ES) for post-damage recovery in a difficult high-dimensional control task where traditional ME fails. Additionally, we show that ME-ES performs efficient exploration, on par with state-of-the-art exploration algorithms in high-dimensional control tasks with strongly deceptive rewards.

description: We investigate the ability of infrared integral-field spectrographs to map the velocity fields of high redshift galaxies, presenting a formalism which may be applied to any telescope and imaging spectrograph system. We discuss the 5-sigma limiting line fluxes which current integral-field spectrographs will reach, and extend this discussion to consider future large aperture telescopes with cryogenically cooled adaptive reimaging optics. In particular, we simulate observations of spectral line emission from star-forming regions at redshifts z = 0.5 to 2.5 using a variety of spatial sampling scales and give predictions for the signal-to-noise ratio expected as a function of redshift. Using values characteristic of the W.M. Keck II telescope and the new OH-Suppressing InfraRed Imaging Spectrograph (OSIRIS) we calculate integral-field signal-to-noise ratio maps for a sample of U_nGR color-selected star-forming galaxies at redshift z ~ 2 - 2.6 and demonstrate that OSIRIS will be able to reconstruct the two-dimensional projected velocity fields of these galaxies on scales of 100 mas (~ 1 kpc at redshift z ~ 2). With signal-to-noise ratios per spatial sample up to ~ 20, OSIRIS will in some cases be able to distinguish between merger activity and ordered disk rotation. Structures on scales smaller than 1 kpc may be detected by OSIRIS for particularly bright sources, and will be easy targets for future 30m class telescopes.

description: About 49 million Americans – roughly 15% of entire America - live in households that lack the means to get enough nutritious food on a regular basis. Past experiences and fear of food accessibility could affect the quality of diet and eating behavior in many ways. In this study we examine long-term trends in food insecurity and obesity over a 20-year period. We specifically examine the changing role of health behaviors in the association between food insecurity and obesity. Most studies on this topic have conducted cross-sectional analysis. Examining this association over time would help us make more careful considerations in making policies. Until recently, it was assumed that the only reason for being overweight was excessive eating. Food insecurity could also cause weight gain due to adverse social and physical environments with identifiable risk factors. It is imperative to know that food security and poverty are both forms of material deficit which bring about a range of detrimental results such as excess weight gain. Food insecurity is a continuum of experiences ranging from the most extreme form, starvation, to complete food security and changes in food security status can be temporary, cyclical, medium or long term.

description: We present a measurement of the double longitudinal spin asymmetry in inclusive pi^0 production in polarized proton-proton collisions at sqrt(s)=200 GeV. The data were taken at the Relativistic Heavy Ion Collider with average beam polarizations of 26%. The measurements are the first of a program to study the longitudinal spin structure of the proton, using strongly interacting probes, at collider energies. The asymmetry is presented for transverse momenta 1-5 GeV/c at mid-rapidity, where next-to-leading order perturbative quantum chromodynamic (NLO pQCD) calculations describe the unpolarized cross section well. The observed asymmetry is small and is compared with a NLO pQCD calculation with a range of polarized gluon distributions.

description: An exact method is suggested to treat the nonlinear self-interactions (NLSI) in the relativistic Hartree-Fock (RHF) approach for nuclear systems. We consider here the NLSI constructed from the relativistic scalar nucleon densities and including products of six and eight fermion fields. This type of NLSI corresponds to the zero range limit of the standard cubic and quartic self-interactions of the scalar field. The method to treat the NLSI uses the Fierz transformation, which enables one to express the exchange (Fock) components in terms of the direct (Hartree) ones. The method is applied to nuclear matter and finite nuclei. It is shown that, in the RHF formalism, the NLSI, which are explicitly isovector-independent, generate scalar, vector and tensor nucleon self-energies strongly density-dependent. This strong isovector structure of the self-energies is due to the exchange terms of the RHF method. Calculations are carried out with a parametrization containing five free parameters. The model allows a description of both types of systems compatible with experimental data.

description: Domain classification is the fundamental task in natural language understanding (NLU), which often requires fast accommodation to new emerging domains. This constraint makes it impossible to retrain all previous domains, even if they are accessible to the new model. Most existing continual learning approaches suffer from low accuracy and performance fluctuation, especially when the distributions of old and new data are significantly different. In fact, the key real-world problem is not the absence of old data, but the inefficiency to retrain the model with the whole old dataset. Is it potential to utilize some old data to yield high accuracy and maintain stable performance, while at the same time, without introducing extra hyperparameters? In this paper, we proposed a hyperparameter-free continual learning model for text data that can stably produce high performance under various environments. Specifically, we utilize Fisher information to select exemplars that can "record" key information of the original model. Also, a novel scheme called dynamical weight consolidation is proposed to enable hyperparameter-free learning during the retrain process. Extensive experiments demonstrate that baselines suffer from fluctuated performance and therefore useless in practice. On the contrary, our proposed model CCFI significantly and consistently outperforms the best state-of-the-art method by up to 20% in average accuracy, and each component of CCFI contributes effectively to overall performance.

Quando se estuda sobre a utilização de condicionadores de energia, nos deparamos com muitas soluções no mercado e em algumas delas, mesmo sendo parecidas, existem muitos termos e diferentes arranjos que podem ser um ponto a mais para gerar dúvidas na hora de definir esse tipo de aplicação. A pesquisa foi elaborada com base nas informações de alguns fabricantes de UPS e normas, onde houve um estudo sobre suas topologias, características gerais e comparativos entre suas tecnologias e prosseguiu com um estudo de caso, em que cruzou-se algumas medições de energia elétrica, tensão, frequência e outras grandezas pertinentes de um indústria do ramo alimentício com os índices da ANEEL, finalizando com os resultados obtidos nessa mesma indústria ao se utilizar uma UPS. Os resultados desse estudo mostram que é possível ter uma melhoria na energia elétrica com o emprego desse equipamento, aqui detalhado como UPS Rotativa, independentemente da qualidade da energia elétrica que chega ao ponto de entrega da concessionária distribuidora e a utilização desses equipamentos pode trazer muitos outros benefícios como não ser mais necessário o uso de banco de capacitores, reguladores de tensão e até mesmo filtros para eliminação de conteúdo harmônico. Apesar da pesquisa ser voltada para o consumidor industrial, o mesmo conceito pode ser aplicado em outros setores onde há criticidade em seus processos e uma falha no fornecimento de energia elétrica pode acarretar em grandes prejuízos financeiros e riscos para pessoas.

description: WiFi signal has become accessible everywhere, providing high-speed data transmission experience. Besides the communication service, channel state information (CSI) of the WiFi signals is widely employed for numerous Internet of Things (IoT) applications. Recently, most of these applications are based on analysis of the microwave reflections caused by physical movement of the objective. In this paper, a novel contactless wireless sensing technique named WiEps is developed to measure the dielectric properties of the material, exploiting the transmission characteristics of the WiFi signals. In WiEps, the material under test is placed between the transmitter antenna and receiver antenna. A theoretical model is proposed to quantitatively describe the relationship between CSI data and dielectric properties of the material. During the experiment, the phase and amplitude of the transmitted WiFi signals are extracted from the measured CSI data. The parameters of the theoretical model are calculated using measured data from the known materials. Then, WiEps is utilized to estimate the dielectric properties of unknown materials. The proposed technique is first applied to the ethanol/water mixtures. Then, additional liquids are measured for further verification. The estimated permittivities and conductivities show good agreement with the actual values, with the average error of 4.0% and 8.9%, respectively, indicating the efficacy of WiEps. By measuring the dielectric property, this technique is promising to be applied to new IoT applications using ubiquitous WiFi signals, such as food engineering, material manufacturing process monitoring, and security check.

description: For the first time in the history of high energy astronomy, a large CdTe gamma-ray camera is operating in space. ISGRI is the low-energy camera of the IBIS telescope on board the INTEGRAL satellite. This paper details its design and its in-flight behavior and performances. Having a sensitive area of 2621 cm$^2$ with a spatial resolution of 4.6 mm, a low threshold around 12 keV and an energy resolution of $\sim$ 8% at 60 keV, ISGRI shows absolutely no signs of degradation after 9 months in orbit. All aspects of its in-flight behavior and scientific performance are fully nominal, and in particular the observed background level confirms the expected sensitivity of 1 milliCrab for a 10$^6$s observation.

description: The new Student Union Building, to be completed in 2014, at the Vancouver campus of University of British Columbia will collect rainwater through the rooftop for non-potable use in the building. A study is conducted to investigate on a possible water treatment process after the rainwater has been collected. The proposed design includes filtration, disinfection, and overflow and back-flow preventions. In the water treatment system, the collected rainwater first runs through a filter to remove the large pathogens. The biosand filter is used to filter the water and is capable of eliminating greater than 90% of the coliforms. The biosand filter is chosen primarily due to its low impact on the environment, zero energy consumption during operation, and inexpensive costs. Then, the rainwater is disinfected by ultraviolet light to ensure all bacteria are removed. The system also contains sensor and control valves in the case of water overflow or backflow. Both the biosand filter and the ultraviolet disinfection methods have low impact on the environment and present no significant harm to humans during operation. The cost of biosand filter is extremely low to purchase, to maintain and to operate. Although the ultraviolet system is more expensive, it operates at low cost and will balance the cost after a period of usage. The proposed system is recommended based on the investigation performed, as each component has been evaluated to be affordable and sustainable.

description: Neutron elastic and inelastic scattering measurements have been performed in order to investigate the spin structure and the magnetic excitations in the impurity-induced antiferromagnetic ordered phase of the doped spin gap system Tl(Cu$_{1-x}$Mg$_x$)Cl$_3$ with $x=0.03$. The magnetic Bragg reflections indicative of the ordering were observed at ${\pmb Q}=(h, 0, l)$ with integer $h$ and odd $l$ below $T_{\rm N}=3.45$ K. It was found that the spin structure of the impurity-induced antiferromagnetic ordered phase on average in Tl(Cu$_{1-x}$Mg$_x$)Cl$_3$ with $x=0.03$ is the same as that of the field-induced magnetic ordered phase for ${\pmb H} \parallel b$ in the parent compound TlCuCl$_3$. The triplet magnetic excitation was clearly observed in the $a^*$-$c^*$ plane and the dispersion relations of the triplet excitation were determined along four different directions. The lowest triplet excitation corresponding to the spin gap was observed at ${\pmb Q}=(h, 0, l)$ with integer $h$ and odd $l$, as observed in TlCuCl$_3$. It was also found that the spin gap increases steeply below $T_{\rm N}$ upon decreasing temperature. This strongly indicates that the impurity-induced antiferromagnetic ordering coexists with the spin gap state in Tl(Cu$_{1-x}$Mg$_x$)Cl$_3$ with $x=0.03$.

description: High-performance computing, together with a neural network model trained from data generated with first-principles methods, has greatly boosted applications of \textit{ab initio} molecular dynamics in terms of spatial and temporal scales on modern supercomputers. Previous state-of-the-art can achieve $1-2$ nanoseconds molecular dynamics simulation per day for 100-million atoms on the entire Summit supercomputer. In this paper, we have significantly reduced the memory footprint and computational time by a comprehensive approach with both algorithmic and system innovations. The neural network model is compressed by model tabulation, kernel fusion, and redundancy removal. Then optimizations such as acceleration of customized kernel, tabulation of activation function, MPI+OpenMP parallelization are implemented on GPU and ARM architectures. Testing results of the copper system show that the optimized code can scale up to the entire machine of both Fugaku and Summit, and the corresponding system size can be extended by a factor of $134$ to an unprecedented $17$ billion atoms. The strong scaling of a $13.5$-million atom copper system shows that the time-to-solution can be 7 times faster, reaching $11.2$ nanoseconds per day. This work opens the door for unprecedentedly large-scale molecular dynamics simulations based on {\it ab initio} accuracy and can be potentially utilized in studying more realistic applications such as mechanical properties of metals, semiconductor devices, batteries, etc. The optimization techniques detailed in this paper also provide insight for relevant high-performance computing applications.

description: During its first solar encounter, the Parker Solar Probe (PSP) acquired unprecedented up-close imaging of a small Coronal Mass Ejection (CME) propagating in the forming slow solar wind. The CME originated as a cavity imaged in extreme ultraviolet that moved very slowly ($<50$ km/s) to the 3-5 solar radii (R$_\odot$) where it then accelerated to supersonic speeds. We present a new model of an erupting Flux Rope (FR) that computes the forces acting on its expansion with a computation of its internal magnetic field in three dimensions. The latter is accomplished by solving the Grad-Shafranov equation inside two-dimensional cross sections of the FR. We use this model to interpret the kinematic evolution and morphology of the CME imaged by PSP. We investigate the relative role of toroidal forces, momentum coupling, and buoyancy for different assumptions on the initial properties of the CME. The best agreement between the dynamic evolution of the observed and simulated FR is obtained by modeling the two-phase eruption process as the result of two episodes of poloidal flux injection. Each episode, possibly induced by magnetic reconnection, boosted the toroidal forces accelerating the FR out of the corona. We also find that the drag induced by the accelerating solar wind could account for about half of the acceleration experienced by the FR. We use the model to interpret the presence of a small dark cavity, clearly imaged by PSP deep inside the CME, as a low-density region dominated by its strong axial magnetic fields.
