description: Purpose: The purpose of this study was to explore demographic characteristics, job satisfaction, workload, challenges and rewards of working in academia, and recruitment/retention advice and recommendations for faculty of color (FOC) in communication sciences and disorders (CSD).Method: A 43-item anonymous survey, composed of 38 closed-ended and five open-ended questions, was used to collect information from CSD FOC. Thematic analysis was used to capture trends in participant responses.Results: The responses of FOC in communication disorders to closed-ended questions indicated that they were satisfied with their jobs. Overall, FOC reported spending a significant amount of their time on teaching and student-related activities. They also identified several common rewards and challenges of working in academia and offered key suggestions, advice, and recommendations to students, administrators, and the field. FOC responses to open-ended questions revealed noteworthy concerns related to racialized practices.Conclusion: Research, policy, and practice focused on the needs of FOC must explicitly examine and address racism in CSD if the field is to develop adequate strategies and mechanisms to support the recruitment and retention of FOC.

J/psi and psi(2S) production in pp collisions at sqrt(s) = 7 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A measurement of the J/psi and psi(2S) production cross sections in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 inverse picobarns. Using a fit to the invariant mass and decay length distributions, production cross sections have been measured separately for prompt and non-prompt charmonium states, as a function of the meson transverse momentum in several rapidity ranges. In addition, cross sections restricted to the acceptance of the CMS detector are given, which are not affected by the polarization of the charmonium states. The ratio of the differential production cross sections of the two states, where systematic uncertainties largely cancel, is also determined. The branching fraction of the inclusive B to psi(2S) X decay is extracted from the ratio of the non-prompt cross sections to be: BR(B to psi(2S) X) = (3.08 +/- 0.12(stat.+syst.) +/- 0.13(theor.) +/- 0.42(BR[PDG])) 10^-3

description: Let α be the maximal value such that the product of an n x n^α matrix by an n^α x n matrix can be computed with n^{2+o(1)} arithmetic operations. In this paper we show that α>0.30298, which improves the previous record α>0.29462 by Coppersmith (Journal of Complexity, 1997). More generally, we construct a new algorithm for multiplying an n x n^k matrix by an n^k x n matrix, for any value k\neq 1. The complexity of this algorithm is better than all known algorithms for rectangular matrix multiplication. In the case of square matrix multiplication (i.e., for k=1), we recover exactly the complexity of the algorithm by Coppersmith and Winograd (Journal of Symbolic Computation, 1990). These new upper bounds can be used to improve the time complexity of several known algorithms that rely on rectangular matrix multiplication. For example, we directly obtain a O(n^{2.5302})-time algorithm for the all-pairs shortest paths problem over directed graphs with small integer weights, improving over the O(n^{2.575})-time algorithm by Zwick (JACM 2002), and also improve the time complexity of sparse square matrix multiplication.

description: In this paper, we study the logarithmic terms in the partition functions of CFTs with boundaries (BCFTs). In three dimensions, their coefficients give the boundary central charges, which are conjectured to be monotonically decreasing functions under the RG flows. We present a few supporting evidences from field theory calculations. In two dimensions, we give a holographic construction (AdS/BCFT) for an arbitrary shape of boundary and calculate its logarithmic term as well as boundary energy momentum tensors, confirming its consistency with the Weyl anomaly. Moreover, we give perturbative solutions of gravity duals for the three dimensional BCFTs with any shapes of boundaries. We find that the standard Fefferman-Graham expansion breaks down for generic choices of BCFT boundaries.

description: Student understanding in the field of electrical engineering has been researched for some time. Especially the research of student ideas regarding DC circuits has been given special focus in previous studies. It has been observed that the majority of the students assume the voltage across an open switch to be zero. Further, the studies proposed several student misconceptions that caused this incorrect assumption. In this work, two sets of student interviews were conducted and analyzed. The interviewed students were enrolled in an undergraduate course in electrical engineering at Hamburg University of Technology. In the first set of interviews, the proposed misconceptions were confirmed. Further, additional misconceptions were observed. The observed misconceptions can be categorized into misconceptions regarding the open switch and misconceptions regarding the general understanding of voltage. In total, eight different misconceptions have been observed. In this work, all misconceptions are identified and characterized with the help of student quotes. The second set of interviews was used to investigate how the students' understanding changed throughout the continued studies in electrical engineering over the course of the lecture. Moreover, based on the observed student misconceptions, a questionnaire was developed that can be used to detect misconceptions among a larger group of students.
Using Twitter data to analyse the spatial patterns of online anti-immigration sentiment in the UK

description: There is a growing academic literature examining anti-immigration sentiment posted onto social media platforms, with evidence emerging of its impact on rises in “real physical” incidents of hate. Despite this, little is understood about the spatial pattern of the production of online anti-immigration content and contextual factors contributing to shaping its spatial configuration. This study aims to use Twitter data and natural language processing to analyse spatial patterns of online sentiment towards immigration across sub-regional areas of the UK, and identify key demographic and contextual factors associated with the production of anti-immigration sentiment on social media platforms.

description: We describe a mission architecture designed to substantially increase the science capability of the NASA Science Mission Directorate (SMD) Astrophysics Explorer Program for all AO proposers working within the near-UV to far-infrared spectrum. We have demonstrated that augmentation of Falcon 9 Explorer launch services with a 13 kW Solar Electric Propulsion (SEP) stage can deliver a 700 kg science observatory payload to extra-Zodiacal orbit. This new capability enables up to ~13X increased photometric sensitivity and ~160X increased observing speed relative to a Sun-Earth L2, Earth-trailing, or Earth orbit with no increase in telescope aperture. All enabling SEP stage technologies for this launch service augmentation have reached sufficient readiness (TRL-6) for Explorer Program application in conjunction with the Falcon 9. We demonstrate that enabling Astrophysics Explorers to reach extra-zodiacal orbit will allow this small payload program to rival the science performance of much larger long development time systems; thus, providing a means to realize major science objectives while increasing the SMD Astrophysics portfolio diversity and resiliency to external budget pressure. The SEP technology employed in this study has strong applicability to SMD Planetary Science community-proposed missions. SEP is a stated flight demonstration priority for NASA's Office of the Chief Technologist (OCT). This new mission architecture for astrophysics Explorers enables an attractive realization of joint goals for OCT and SMD with wide applicability across SMD science disciplines.

We prove that (i) The hypergraph $\mathcal{H}$ admits proper vertex coloring in $k+1$ colors. (ii) The hypergraph $\mathcal{H}$ admits proper vertex coloring in $k$ colors, if $δ\ge 3$ and $k\ge 3$. As a consequence of these results we derive upper bounds on the number of colors in dynamic colorings.

A formal verification of the theory of parity complexes
Creators: name: Buckley, Mitchell

Year: 2015
Subjects: parity complex; omega category; category; pasting diagram; excision of extremals

description: We formalise, in Coq, the opening sections of Parity Complexes [Street1991] up to and including the all important excision of extremals algorithm. Parity complexes describe the essential combinatorial structure exhibited by simplexes, cubes and globes, that enable the construction of free omega categories on such objects. The excision of extremals is a recursive algorithm that presents every cell in such a category as a composite of atomic cells, this is the sense in which the omega category is free. Due to the complicated multi-dimensional nature of this work, the detail of definitions and proofs can be hard to follow and verify. Indeed, some corrections [Street1994] were required some years following the original publication.

Our formalisation verifies that all cases of each result operate as stated. In particular, we indicate which portions of the theory can be proved directly from definitions, and which require more subtle and complex arguments. By identifying results that require the most complicated proofs, we are able to investigate where this theory might benefit from further study and which results need to be considered most carefully in future work.

description: The March 2011 outburst of the poorly-studied cataclysmic variable NSV 1436 offered an opportunity to decide between dwarf nova and recurrent nova classifications. We use seven daily observations in the X-ray and UV by the Swift satellite, together with AAVSO V photometry, to characterise the outburst and decline behaviour. The short optical outburst coincided with a faint and relatively soft X-ray state, whereas in decline to fainter optical magnitudes the X-ray source was harder and brighter. These attributes, and the modest optical outburst amplitude, indicate that this was a dwarf nova outburst and not a recurrent nova. The rapid optical fading suggests an orbital period below 2 hours.

description: By transforming an exact stability condition, a new Nyquist-like plot is proposed to predict occurrences of three typical instabilities in DC-DC converters. The three instabilities are saddle-node bifurcation (coexistence of multiple solutions), period-doubling bifurcation (subharmonic oscillation), and Neimark bifurcation (quasi-periodic oscillation). In a single plot, it accurately predicts whether an instability occurs and what type the instability is. The plot is equivalent to the Nyquist plot, and it is a useful design tool to avoid these instabilities. Nine examples are used to illustrate the accuracy of this new plot to predict instabilities in the buck or boost converter with fixed or variable switching frequency.

description: In a recent publication [Phys. Rev. E \textbf{83}, 011301 (2011)], Vollmayr--Lee \emph{et al.} have determined by computer simulations the thermal diffusivity and the longitudinal viscosity coefficients of a driven granular fluid of hard spheres at intermediate volume fractions. Although they compare their simulation results with the predictions of kinetic theory, they use the dilute expressions for the driven system and the modified Sonine approximations for the undriven system. The goal here is to carry out this comparison by proposing a modified Sonine approximation to the Enskog equation for driven granular fluids that leads to a better quantitative agreement.

description: For single particle electron cryo-microscopy (cryoEM), contrast loss due to beam-induced charging and specimen movement is a serious problem, as the thin films of vitreous ice spanning the holes of a holey carbon film are particularly susceptible to beam-induced movement. We demonstrate that the problem is at least partially solved by carbon nanotechnology. Doping ice-embedded samples with single-walled carbon nanotubes (SWNT) in aqueous suspension or adding nanocrystalline graphene supports, obtained by thermal conversion of cross-linked self-assembled biphenyl precursors, significantly reduces contrast loss in high-resolution cryoEM due to the excellent electrical and mechanical properties of SWNTs and graphene.

description: European Union (EU) leaders recently agreed a more ambitious 2030 climate target which, among other things, means at least doubling the annual overall energy renovation rate of 1%. In this context, intensified actions to rapidly accelerate the decarbonisation of the building sector are needed. However, retrofit actions are hindered by barriers at different stages: from the initial decision to renovate, to financing and completing energy efficiency projects. To overcome these barriers, it is necessary to act on different fronts to foster better use of EU and national public funds and mobilise a greater share of private funds. EU and national public funds should be better communicated and target end-users more effectively.
 Innovative financing solutions can be found in performance-based schemes, like pay for performance (P4P), which have been used so far to engage both energy and third-party service providers, mainly in North American energy efficiency projects. In P4P schemes, financial flows between the parties involved are linked to the actual/ metered and weather-normalised energy savings produced by the retrofit project. P4P schemes also rely on energy efficiency aggregators, which group buildings together into an energy savings portfolio. The energy efficiency aggregator usually acts as the intermediary between the client and the programme implementer and is compensated for delivering energy savings. However, despite the benefits that P4P models may provide, they have not yet been adopted in the EU.
 This report focuses on ways that policy and regulatory developments in the EU may become risks or opportunities for P4P schemes. In particular, the main goal of this study is to analyse the directives, policies and measures already adopted, as well as those under consideration by the EU. Based on a comprehensive literature review, a Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis, interviews with key stakeholders from the field, and an EU-wide online survey, we identify regulatory opportunities for P4P schemes considering the different policy measures and market uptakes. Finally, based on insights from all the different parts of our work, we devise and present ten (10) integrated strategies for rolling-out P4P schemes in the EU, by considering existing and upcoming regulatory frameworks, the exploitation of opportunities that may emerge and adaptation to potentially unfavourable developments.

description: In network coding a constant dimension code consists of a set of k-dimensional subspaces of F_q^n. Orbit codes are constant dimension codes which are defined as orbits of a subgroup of the general linear group, acting on the set of all subspaces of F_q^n. If the acting group is cyclic, the corresponding orbit codes are called cyclic orbit codes. In this paper we give a classification of cyclic orbit codes and propose a decoding procedure for a particular subclass of cyclic orbit codes.

description: Planets can emit polarized thermal radiation, just like brown dwarfs. We present calculated thermal polarization signals from hot exoplanets, using an advanced radiative transfer code that fully includes all orders of scattering by gaseous molecules and cloud particles. The code spatially resolves the disk of the planet, allowing simulations for horizontally inhomogeneous planets. Our results show that the degree of linear polarization, P, of an exoplanet's thermal radiation is expected to be highest near the planet's limb and that this P depends on the temperature and its gradient, the scattering properties and the distribution of the cloud particles. Integrated over the disk of a spherically symmetric planet, P of the thermal radiation equals zero. However, for planets that appear spherically asymmetric, e.g. due to flattening, cloud bands or spots in their atmosphere, differences in their day and night sides, and/or obscuring rings, P is often larger than 0.1 %, in favorable cases even reaching several percent at near-infrared wavelengths. Detection of thermal polarization signals can give access to planetary parameters that are otherwise hard to obtain: it immediately confirms the presence of clouds, and P can then constrain atmospheric inhomogeneities and the flattening due to the planet's rotation rate. For zonally symmetric planets, the angle of polarization will yield the components of the planet's spin axis normal to the line-of-sight. Finally, our simulations show that P is generally more sensitive to variability in a cloudy planet's atmosphere than the thermal flux is, and could hence better reveal certain dynamical processes.

description: The performance of fishery extension workers has been affected by the COVID-19 pandemic, either directly or indirectly. The impact is seen especially in matters related to physical contact and gathering large numbers of people. The condition of the COVID-19 pandemic is still not predictable until when it will end. The function of the extension agent as a catalyst for economic development efforts, especially the main actors in fisheries, is that fishery extension workers must have an adaptive strategy in carrying out their duties during the COVID-19 pandemic. One of these strategies is the use of information and communication technology, which is currently growing rapidly. This study aimed to analyze the conditions and characteristics of the implementation of fishery counseling by optimally utilizing information and communication technology during the COVID-19 pandemic. This research design is survey research with a qualitative descriptive approach because the information collected will be analyzed qualitatively. The quota sampling technique carried out the sample collection method in this study. The resource persons who were sampled in the survey were fishery instructors, totaling 140 people. Fishery instructors are still active in carrying out their duties during the pandemic with strict health protocols, although with a relatively decreased intensity since the beginning of the pandemic until now. The characteristics of fishery instructors in carrying out their duties are still varied; some still work face-to-face physically, and some have implemented Work from Home (WFH). Research data shows the condition of extension workers who have experienced symptoms similar to COVID-19 patients as much as 25.71 percent and confirmed reactive or positively exposed to COVID-19 virus infection as much as 24.29 percent. Fisheries extension strategies and methods are carried out offline and online with strict health protocols and various communication technology products.

description: On September 16, 2014, staff from NOAA Fisheries' Hawaiian Monk Seal Research Program (HMSRP) completed their second ever land-based survey of monk seals on the island of Ni'ihau. The survey took place at the end of R/V Oscar Elton Sette project SE 14-06. Permanent HMSRP staff, temporary field staff and two personnel representing the US Navy participated in the survey. Two survey methods were utilized to cover the Ni'ihau and Lehua Rock coastlines. The first was a land-based survey via truck, horseback, and on foot that was conducted in areas accessible on land by three separate survey teams concurrently. Each land survey team included HMSRP personnel and Ni'ihau residents who served as guides (red, orange and green tracks; Figure 1). One land team also included US Navy representatives. The second survey method was by boat using Sette small boat SE-2 for Lehua Rock. The boat survey team was staffed only with HMSRP personnel and a Sette coxswain...One portion of the coastline...was not surveyed. This area is not accessible by foot and consists of sheer cliffs with little haulout area for seals. This area was surveyed by boat in September 2013, when 8 seals were observed hauled out along the coastline. This portion of the island proved to be very difficult for obtaining useful identifying information on any seals seen, due to rough sea conditions along the shore. Additionally, it was prohibitively time consuming for the ship to travel to that area of the coast in order to launch the small boat to do the survey. Therefore, it was determined that this area of the coast would not be covered for the 2014 survey. It will be considered for future survey efforts. All teams conducted a census-type survey in which all individual seals encountered in the survey area were recorded. Size, sex, and any identifying information were collected. Land survey teams took photographs of seals whenever possible, while minimizing seal disturbance, to document any identifying marks including tags, scars, and applied or natural bleaches.

description: We developed a new physical model to predict macroscopic properties of inorganic molten systems using a realistic description of inter-atomic interactions. Unlike the conventional approach, which tends to overestimate viscosity by several times, our systems consist of a set of ions with an admixture of neutral atoms. The neutral atom subsystem is a consequence of the covalent/ionic state reduction, occurring in the liquid phase. Comparison of the calculated macroscopic properties (shear viscosity and self-diffusion constants) with the experiment demonstrates good performance of our model. The presented approach is inspired by a significant degree of covalent interaction between the alkali and chlorine atoms, predicted by the coupled cluster theory.

 publication range in 2021, as well as several articles published in 2020, using Google Scholar as the
 primary database to demonstrate the urgency of modern education transformation and grounded
 thinking. What I discovered was that Human Development Index-ideas, were intertwined with the
 issues of change and education. Through local to international academics, Indonesia is characterized
 through a variety of discourses and studies. In terms of the HDI, development participation may be
 defined as awareness, cooperation, understanding, adoption and adaptation, and reflection. Community
 involvement as a national framework may result in quantifiable progress, or transformation, in all
 sectors, and Indonesian education can satisfy global standards, even if the government does not always

description: With the growing popularity of machine learning (ML), regression problems in many domains are becoming increasingly high-dimensional. Identifying relevant features from a high-dimensional dataset still remains a significant challenge for building highly accurate machine learning models. Evolutionary feature selection has been used for high-dimensional symbolic regression using Genetic Programming (GP). While grammar based GP, especially Grammatical Evolution (GE), has been extensively used for symbolic regression, no systematic grammar-based feature selection approach exists. This work presents a grammar?based feature selection method, Production Ranking based Feature Selection (PRFS), and reports on the results of its application in symbolic regression. The main contribution of our work is to demonstrate that the proposed method can not only consistently select the most rele?vant features, but also significantly improves the generalization performance of GE when compared with several state-of-the-art ML-based feature selection methods. Experimental results on benchmark symbolic regression problems show that the generalization performance of GE using PRFS was significantly better than that of a state-of-the-art Random Forest based feature selection in three out of four problems, while in fourth problem the performance was the same.

description: Detailed spectral analysis of the Galactic X-ray background emission, or the Galactic Ridge X-ray Emission (GRXE), is presented. To study the origin of the emission, broad-band and high-quality GRXE spectra were produced from 18 pointing observations with Suzaku in the Galactic bulge region, with the total exposure of 1 Ms. The spectra were successfully fitted by a sum of two major spectral components; a spectral model of magnetic accreting white dwarfs with a mass of 0.66 (0.59-0.75) solar, and a softer optically-thin thermal emission with a plasma temperature of 1.2-1.5 keV which is attributable to coronal X-ray sources. When combined with previous studies which employed high spatial resolution of the Chandra satellite (e.g. Revnivtsev et al. 2009, Nature), the present spectroscopic result gives another strong support to a scenario that the GRXE is essentially an assembly of numerous discrete faint X-ray stars. The detected GRXE flux in the hard X-ray band was used to estimate the number density of the unresolved hard X-ray sources. When integrated over a luminosity range of ~10^30-10^34 erg/s, the result is consistent with a value which was reported previously by directly resolving faint point sources.

description: An increasing demand of environmental radioactivity monitoring comes both from the scientific community and from the society. This requires accurate, reliable and fast response preferably from portable radiation detectors. Thanks to recent improvements in the technology, $γ$-spectroscopy with sodium iodide scintillators has been proved to be an excellent tool for in-situ measurements for the identification and quantitative determination of $γ$-ray emitting radioisotopes, reducing time and costs. Both for geological and civil purposes not only $^{40}$K, $^{238}$U, and $^{232}$Th have to be measured, but there is also a growing interest to determine the abundances of anthropic elements, like $^{137}$Cs and $^{131}$I, which are used to monitor the effect of nuclear accidents or other human activities. The Full Spectrum Analysis (FSA) approach has been chosen to analyze the $γ$-spectra. The Non Negative Least Square (NNLS) and the energy calibration adjustment have been implemented in this method for the first time in order to correct the intrinsic problem related with the $χ^2$ minimization which could lead to artifacts and non physical results in the analysis. A new calibration procedure has been developed for the FSA method by using in situ $γ$-spectra instead of calibration pad spectra. Finally, the new method has been validated by acquiring $γ$-spectra with a 10.16 cm x 10.16 cm sodium iodide detector in 80 different sites in the Ombrone basin, in Tuscany. The results from the FSA method have been compared with the laboratory measurements by using HPGe detectors on soil samples collected in the different sites, showing a satisfactory agreement between them. In particular, the $^{137}$Cs isotopes has been implemented in the analysis since it has been found not negligible during the in-situ measurements.

description: Mobile Ad-hoc Networks (MANETS) is a collection of wireless nodes without any infrastructure support. The nodes in MANET can act as either router or source and the control of the network is distributed among nodes. The nodes in MANETS are highly mobile and it maintains dynamic interconnection between those mobile nodes. MANTEs have been considered as isolated stand-alone network. This can turn the dream of networking "at any time and at any where" into reality. The main purpose of this paper is to study the issues in route discovery process in AODV protocol for MANET. Flooding of route request message imposes major concern in route establishment. This paper suggests a new approach to reduce the routing overhead during the route discovery phase. By considering the previous behaviour of the network, the new protocol reduces the unwanted searches during route establishment process
