description: WLM is a dwarf irregular that is seen almost edge-on that has prompted a number of kinematical studies investigating its rotation curve and its dark matter content. In this paper, we investigate the origin of the strong asymmetry of the rotation curve, which shows a significant discrepancy between the approaching and the receding side. We first examine whether an $m = 1$ perturbation (lopsidedness) in the halo potential could be a mechanism creating such kinematical asymmetry. To do so, we fit a theoretical rotational velocity associated with an $m = 1$ perturbation in the halo potential model to the observed data via a $χ-$squared minimization method. We show that a lopsided halo potential model can explain the asymmetry in the kinematic data reasonably well. We then verify that the kinematical classification of WLM shows that its velocity field is significantly perturbed due to both its asymmetrical rotation curve and also its peculiar velocity dispersion map. In addition, based on a kinemetry analysis, we find that it is possible for WLM to lie in the transition region, where the disk and merger coexist. In conclusion, it appears that the rotation curve of WLM diverges significantly from that of an ideal rotating disk, which may significantly affect investigations of its dark matter content.

description: Distributed networks and real-time systems are becoming the most important components for the new computer age, the Internet of Things (IoT), with huge data streams or data sets generated from sensors and data generated from existing legacy systems. The data generated offers the ability to measure, infer and understand environmental indicators, from delicate ecologies and natural resources to urban environments. This can be achieved through the analysis of the heterogeneous data sources (structured and unstructured). In this paper, we propose a distributed framework Event STream Processing Engine for Environmental Monitoring Domain (ESTemd) for the application of stream processing on heterogeneous environmental data. Our work in this area demonstrates the useful role big data techniques can play in an environmental decision support system, early warning and forecasting systems. The proposed framework addresses the challenges of data heterogeneity from heterogeneous systems and real time processing of huge environmental datasets through a publish/subscribe method via a unified data pipeline with the application of Apache Kafka for real time analytics.

description: In this work, we present a data-driven framework for generating diverse in-betweening motions for kinematic characters. Our approach injects dynamic conditions and explicit motion controls into the procedure of motion transitions. Notably, this integration enables a finer-grained spatial-temporal control by allowing users to impart additional conditions, such as duration, path, style, etc., into the in-betweening process. We demonstrate that our in-betweening approach can synthesize both locomotion and unstructured motions, enabling rich, versatile, and high-quality animation generation.

description: The pulsating DA white dwarfs are the coolest degenerate stars that undergo self-driven oscillations. Understanding their interior structure will help to understand the previous evolution of the star. To this end, we report the analysis of more than 200 h of time-resolved CCD photometry of the pulsating DA white dwarf star EC 14012-1446 acquired during four observing epochs in three different years, including a coordinated three-site campaign. A total of 19 independent frequencies in the star's light variations together with 148 combination signals up to fifth order could be detected. We are unable to obtain the period spacing of the normal modes and therefore a mass estimate of the star, but we infer a fairly short rotation period of 0.61 +/- 0.03 d, assuming the rotationally split modes are l=1. The pulsation modes of the star undergo amplitude and frequency variations, in the sense that modes with higher radial overtone show more pronounced variability and that amplitude changes are always accompanied by frequency variations. Most of the second-order combination frequencies detected have amplitudes that are a function of their parent mode amplitudes, but we found a few cases of possible resonantly excited modes. We point out the complications in the analysis and interpretation of data sets of pulsating white dwarfs that are affected by combination frequencies of the form f_A+f_B-f_C intruding into the frequency range of the independent modes.

description: We calculate the energy and the condensate fraction of a system of trapped bosons interacting via a short-range two-body potential with positive scattering length. The potential is attractive and has a two-body bound state. When the scattering length is small compared to the trap length the system is model independent: all potential models -- attractive, repulsive and zero-range -- provide similar results. When the scattering length is large the attractive model differs qualitatively from the repulsive and zero-range models. In this regime the system with attractive potential becomes independent of the scattering length, with both the energy and the condensate fraction converging towards finite constants.

description: The charge density wave (CDW) state in van der Waals systems shows interesting scaling phenomena as the number of layers can significantly affect the CDW transition temperature, $T_{CDW}$. However, it is often difficult to use conventional methods to study the phase transition in these systems due to their small size and sensitivity to degradation. Degradation is an important parameter which has been shown to greatly influence the superconductivity in layered systems. Since the CDW state competes with the onset of superconductivity, it is expected that $T_{CDW}$ will also be affected by the degradation. Here, we probe the CDW phase transition by the mechanical resonances of suspended 2H-TaS2 and 2H-TaSe2 membranes and study the effect of disorder on the CDW state. Pristine flakes show the transition near the reported values of 75 K and 122 K respectively. We then study the effect of degradation on 2H-TaS2 which displays an enhancement of $T_{CDW}$ up to 129 K after degradation in ambient air. Finally, we study a sample with local degradation and observe that multiple phase transitions occur at 87 K, 103 K and 118 K with a hysteresis in temperature in the same membrane. The observed spatial variations in the Raman spectra suggest that variations in crystal structure cause domains with different transition temperatures which could result in the hysteresis. This work shows the potential of using nanomechanical resonance to characterize the CDW in suspended 2D materials and demonstrate that degradation can have a large effect on transition temperatures.

description: Using a two-channel model, we show that the number of closed channel molecules in a two-component Fermi gas close to a Feshbach resonance is directly related to the derivative of the energy of the gas with respect to the inverse scattering length. We extract this quantity from the fixed node Monte-Carlo equation of state and we compare to the number of closed channel molecules measured in the Rice experiment with lithium [Partridge et al., Phys. Rev. Lett. 95, 020404 (2005)]. We also discuss the effect of a difference between the trapping potentials seen by a closed-channel molecule and by an open-channel pair of atoms in terms of an effective position-dependent scattering length.

description: L. heptapotamicus (Pylnov, 1911).
Redescription of the male and description of the female of this species are given in the article of Bey-Bienko (1951). At the same time, the author notes that the described female may belong to another species, and only additional material can confirm or refute its belonging to this species. This point of view is shared by Childevaev et al. (2013). They collected a series of males and females from the type locality and provided a detailed description of the topotype female. The male (holotype) is a fairly large insect with a body 31 mm long (Table 1). Taxonomic notes. The color uniform, brownish (Fig. 2A); tegmina are shortened and do not reach the posterior edge of the second abdominal tergite (Fig. 2B); cerci in the distal third are curved inward at almost a right angle, with an elongated and pointed tip (Fig. 2C). Titillators. A preparation of the male genitalia (holotype) shows that the titillators have a more massive basal part, their distal part, lacking significant denticles, is almost twice as narrow as the basal part (Fig. 2G).
Bush-crickets collected in Kyrgyzstan were identified as L. heptapotamicus, because they have very similar abdominal terminalia (Fig. 2E) and genitalia (Fig. 2F) and their hind tibia bear 16–20 spines. However, their sizes turned out to be significantly smaller than those of the male and female from the type series (Table 1). Based on this character and the geographic distribution of the known specimens, we find it reasonable to describe a new subspecies of L. heptapotamicus minutus. We believe that this form is not ecologically determined, since all katydids of this species are collected in mountain biotopes (from 1000 m a. s. l.) and have a similar lifestyle: they live on rocky steppes or screes, usually under stones.

We recover some properties and deduce new ones about their isometry group and about their quadratic first integrals of the geodesic equation, and we analyze when these invariant symmetries characterize the family of metrics. We show that the subfamily of the Kerr-NUT solutions are those admitting a Papapetrou field aligned with the Weyl tensor.

description: Ion beams have been widely applied in a few biological research fields such as radioactive breeding, health protection, and tumor therapy. Up to now many interesting and impressive achievements in biology and agriculture have been made. Over the past several decades, scientists in biology, physics, and chemistry have pursued investigations focused on understanding the mechanisms of these radiobiological effects of ion beams. From the chemical point of view, these effects are due to the ion irradiation induced biomolecular damage, direct or indirect. In this review, we will present a chemical overview of the direct effects of ion irradiation upon DNA and its components, based on a review of literature combined with recent experimental results. It is suggested that, under ion bombardment, a DNA molecule undergoes a variety of processes, including radical formation, atomic displacement, intramolecular bond-scissions, emission of fragments, fragment recombination and molecular crosslink, which may lead to genetic mutations or cell death. This may help to understand the mechanisms of the radiobiological effects caused by ion irradiation, such as radiation breeding and tumor therapy.

description: Based on my experience of teaching English to undergraduate students in  Primary Education at the University of Bari, this study is an attempt to  understand why and how to train prospective primary English teachers  (PPETs) about cultural diversity concerning the English-speaking  communities in the United States through the use of children’s  multiethnic literature. The rationale here is to create an awareness  among PPETs of the important role multicultural literature plays in the  lives of children. Indeed, teachers can help children receive  affirmation of themselves and their culture through literature and be  able to connect text to self in order to promote greater meaning. With  this in mind, this paper aims to explore PPETs’ understanding of the use  of multicultural varieties of the English language and literature in  the classroom. To this purpose, specific children’s multicultural texts  have been selected (see References) from two ‘minor’ ethnic literatures in the U.S., that is the African-American and the Chicana.

description: Registration algorithms, such as Iterative Closest Point (ICP), have proven effective in mobile robot localization algorithms over the last decades. However, they are susceptible to failure when a robot sustains extreme velocities and accelerations. For example, this kind of motion can happen after a collision, causing a point cloud to be heavily skewed. While point cloud de-skewing methods have been explored in the past to increase localization and mapping accuracy, these methods still rely on highly accurate odometry systems or ideal navigation conditions. In this paper, we present a method taking into account the remaining motion uncertainties of the trajectory used to de-skew a point cloud along with the environment geometry to increase the robustness of current registration algorithms. We compare our method to three other solutions in a test bench producing 3D maps with peak accelerations of 200 m/s^2 and 800 rad/s^2. In these extreme scenarios, we demonstrate that our method decreases the error by 9.26 % in translation and by 21.84 % in rotation. The proposed method is generic enough to be integrated to many variants of weighted ICP without adaptation and supports localization robustness in harsher terrains.

description: This report highlights some of the key insights about how best to support evidence-informed priority setting. It is divided into two parts, the first focuses on the importance of knowing your context as different types of policy decisions will likely warrant different approaches when making and influencing policy decisions to support evidence-informed priority setting. Second, the report provides guidance on how to approach intervening within the defined context. Intervening involves assessing ‘evidence-supply side’ versus ‘evidence-demand side’ approaches to support evidence informed policymaking, as well as evaluating and learning from the use of these approaches.

A descriptive study of the community adjustment of a group of Vancouver schizophrenics
Creators: name: Davis, Simon
Publisher: name: University of British Columbia
Year: 2010

description: A group of schizophrenics living in the community were followed for a two year period, using information collected from files at the community care teams they were attending. Information collected pertained to the subjects' current living situation, style of cohabitation, source of income, geographic mobility and use of clinical services. Social adjustment of the sample was measured by employment status and rehospitalization rate. The resulting description of the population indicated a group with a high degree of disability and dependency; rates of unemployment and rehospitalization were high. The study indicated that residential status and style of cohabitation remained fairly stable over the two year period, but that employment status worsened somewhat. The data delineated a sub-population of young schizophrenics who seemed to be more unstable than the older subjects; the younger group had a significantly higher rehospitalization rate, were more mobile, and were heavier consumers of psychiatric services. In looking for factors that were associated with differential community adjustment it was found that those rehospitalized in the follow-up period tended to be younger, unemployed, more recently in hospital, and more frequent visitors to the community care teams; those who were unemployed at the end of the follow-up period tended to "be male, unmarried, and possessing a poor work history. The description of the study population indicated that this group would require considerable ongoing treatment and support, and that some individuals might be more "at risk" than others. It was also suggested that some of the socio-demographic variables used in this study might be useful diagnostically.

description: Globally, libraries have become learning spaces where people meet to learn and collaborate. This justifies the evolving roles of libraries from the traditional store house of printed materials to ICT driven innovative environment. Though this transformation has been prevalent at the turn of the century, even during the 3rd industrial revolution, it has become more radical as a result of the global advent of the 4th industrial revolution and the subsequent Covid-19 pandemic, and online pivot of March 2020 which made great demands for e-learning as well as electronic learning resources. Consequently, libraries are not only required to collect, process and make available for use information resources, but to provide them remotely in a suitable and systematically accessible manner while making the environment available for other innovative activities. The latter is justified by information system model which positions that the input, process and output must get evolved to meet the demands of the feedback else it atrophies. National Library of Nigeria has geared up to this challenge with a view to support the future of learning in Nigeria and beyond in order to avoid any obvious atrophy that could embrace future untransformed library . The paper presents all the transformational activities of the National library of Nigeria needed to provide for the future of learning. The presentation will encourage other Libraries to take the same or other innovative steps towards providing for the future of learning.

description: The aerial view has traditionally represented a powerful “optical  paradigm” of modern visual culture, being connected to the ideas of  precision, effectiveness and victory, and film studies bring it back to  the “cartographic anxiety” of the early film. In particular, war film  genre habitually uses aerial imagery, satellite and aerial views.  However, little attention has been devoted to the way aerial views are  presented in contemporary war films. This essay aims to investigate how  aerial imagery is used and commented in contemporary films about the  recent Middle-East wars. Indeed, several films reveal a completely  changed attitude and a widespread mistrust towards aerial imagery. By  showing its distance and violence, as well as its ineffectiveness and  fallibility, they illustrate a radical and unprecedented “rhetorical  shift” in cinema and visual culture. As a matter of fact, investigating  what is left today of the original quality of aerial imagery involves  some implications that go far beyond war film genre and radically  question the cartographic mission of the cinematic medium.

Type: — INDONESIA. Bilitoeng, Mangar, sin. dat. (♂), Teijsmann s.n. (lectotype BO [No numerical identifiers found on the sheet], designated here).
Notes: — Three syntypes are indicated in the protologue: Teijsmann s.n. and Ham s.n. from Billiton Island, and Hallier 2444 from Mount Kelam in West Kalimantan (“Borneo Centralis in monte Klam” fide Valeton (1909a)). Unlike the Billiton collections, the calyx morphology of Hallier 2444 from Borneo is inconsistent with the protologue—the length of the calyx and its lobes are much shorter than that stated in the protologue. Moreover, it is different from the Billiton collections by its subglabrous calyx and non-glaucous, glabrous lower leaf surfaces, and is here excluded from the circumscription of T. billitonensis. Only the staminate inflorescence was described in Valeton’s protologue, with a note indicating that the pistillate counterpart was unknown. We identified four relevant sheets from Billiton Island in BO (where Valeton worked from 1892 to 1913): a fruiting collection with both “ Ham 19 ” and “ Burger 15 ” on its label, a sterile sheet labelled only as “ Ham 19 ”, a sterile sheet with both “ Ham 19 ” and “ Teysm. ” written on the label, and a collection by Teijsmann (without collection number) that represents the only staminate specimen. Thus, T. billitonensis is here lectotypified by the Teijsmann collection.

description: Exposure of environmental bacteria to long-term pollution can facilitate recruitment of multidrug-resistant (MDR) genes; these bacteria are referred to as “superbugs”, leading to potential pathogenic outbreaks. To assess the development of superbugs in the environment, we worked on a bacterial genus- Serratia species: which are either pathogenic or beneficial to the environment. A central question in our research was: can whole genome sequencing be used as tool to obtain a comprehensive understanding of MDR in pathogenic bacteria? This approach can facilitate molecular diagnostics on the presence of pathogenic bacteria, enable novel drug design and prevent pathogenic outbreaks like the COVID-19 pandemic. For this project, we advanced our research using a recently isolated Serratia marcescens species strain SRS-8-S-2018 as a model organism, shown to resistant multiple antibiotics. Further, we used several computational methods to understand the traits of our model organism. A genomic map of strain SRS-8-S-2018 revealed several specialty genes for antibiotic resistance, virulence factors, drug targets, and transporters- all of which can render MDR capabilities to this strain. Notably, all the 5 classes of efflux pumps were identified in this model organism, which are: ATP-binding cassette (ABC) superfamily, (MFS), (MATE) family, the small multidrug resistance (SMR), (RND) superfamily. Moreover, an arsenal of β-lactam antibiotic resistance system was also identified in the strain- all these can be good targets to block drug efflux in opportunistic pathogens. We then developed a better understanding of the protein structure of a representative of ABC transporter, which are dominant in this strain; the 3-D protein model demonstrated conserved domains and protein families which can be the basis for effective newly designed antipeptide drugs. Overall, this study advances our understanding on MDR in a model opportunistic pathogen, thus paving the way for precise drug design to mitigate bacterial antibacterial resistance.

description: We present an STZ-based analysis of numerical simulations by Haxton and Liu (HL). The extensive HL data sharply test the basic assumptions of the STZ theory, especially the central role played by the effective disorder temperature as a dynamical state variable. We find that the theory survives these tests, and that the HL data provide important and interesting constraints on some of its specific ingredients. Our most surprising conclusion is that, when driven at various constant shear rates in the low-temperature glassy state, the HL system exhibits a classic glass transition, including super-Arrhenius behavior, as a function of the effective temperature.

description: Urban design is a highly visual discipline that requires visualization for informed decision making. However, traditional urban design tools are mostly limited to representations on 2D displays that lack intuitive awareness. The popularity of head-mounted displays (HMDs) promotes a promising alternative with consumer-grade 3D displays. We introduce UrbanVR, an immersive analytics system with effective visualization and interaction techniques, to enable architects to assess designs in a virtual reality (VR) environment. Specifically, UrbanVR incorporates 1) a customized parallel coordinates plot (PCP) design to facilitate quantitative assessment of high-dimensional design metrics, 2) a series of egocentric interactions, including gesture interactions and handle-bar metaphors, to facilitate user interactions, and 3) a viewpoint optimization algorithm to help users explore both the PCP for quantitative analysis, and objects of interest for context awareness. Effectiveness and feasibility of the system are validated through quantitative user studies and qualitative expert feedbacks.

Lo scritto contro l'orale nel contesto del dialogo platonico: tre esempi dal Fedone
Creators: name: Jedrkiewicz, Stefano
Publisher: name: Annali Online  Lettere - Ferrara
Year: 2013

description: Plato's literary work consists of written dialogues imitating face-to-face dialogical performances. This practice apparently runs against Plato's own principle that a written text is structurally unable to produce as much meaning as an oral exchange, and risks therefore to be unfit for developing a discourse aimed at truth. Three short specific passages are selected out of the Phaedo (the dialogue portraying arguably the most dramatical and philosophically relevant of Socrates' dialogical performances), in order to describe how Plato has faced the challenge he has set to himself, managing to transform his own mimetical description into an inducement to active philosophy for the benefit of the reader. Incidentally, the notion of "authorship" is also being discussed in relation to the literary genre of the Platonic dialogue.

description: With the emergence of pen-enabled tablets and mobile devices, stylus-based interaction has been receiving increasing attention. Unfortunately, styluses available in the market today are all passive instruments that are primarily used for writing and pointing. In this paper, we describe a novel stylus capable of displaying certain vibro-tactile and inertial haptic effects to the user. Our stylus is equipped with two vibration actuators at the ends, which are used to create a tactile sensation of up and down movement along the stylus. The stylus is also embedded with a DC motor, which is used to create a sense of bidirectional rotational torque about the long axis of the pen. Through two psychophysical experiments, we show that, when driven with carefully selected timing and actuation patterns, our haptic stylus can convey movement and rotational torque information to the user. Results from a further psychophysical experiment provide insight on how the shape of the actuation patterns effects the perception of rotational torque effect. Finally, experimental results from our interactive pen-based game show that our haptic stylus is effective in practical settings

description: We present new computational results for symplectic monodromy groups of hypergeometric differential equations. In particular, we compute the arithmetic closure of each group, sometimes justifying arithmeticity. The results are obtained by extending our previous algorithms for Zariski dense groups, based on the strong approximation and congruence subgroup properties.

description: Holographic acoustical tweezers (HAT) based on Archimedes-Fermat spiraling InterDigitated Transducers (S-IDTs) are a versatile tool for the selective manipulation of microparticles [Baudoin et. al., Sci. Adv., 5: eaav1967 (2019)] and cells [Baudoin et. al., Nat. Commu., 11, 4244 (2020)] in a standard microfluidic environment. These binary active holograms produce some focused helical wave, with the ability to trap particles at the vortex core. Yet, all the studies conducted with S-IDTs have so far been restricted to 2D manipulation only. Here we show (i) that 3D radiation trap for microparticles and cells can be obtained with spiraling tweezers with sufficiently large aperture and (ii) that the particles can be displaced axially by simply tuning the driving frequency, without any motion of the transducer. This work opens perspectives for 3D cells and microparticles manipulation with single-beam acoustical tweezers.

Photometric Redshifts and Photometry Errors

description: We examine the impact of non-Gaussian photometry errors on photometric redshift performance. We find that they greatly increase the scatter, but this can be mitigated to some extent by incorporating the correct noise model into the photometric redshift estimation process. However, the remaining scatter is still equivalent to that of a much shallower survey with Gaussian photometry errors. We also estimate the impact of non-Gaussian errors on the spectroscopic sample size required to verify the photometric redshift rms scatter to a given precision. Even with Gaussian {\it photometry} errors, photometric redshift errors are sufficiently non-Gaussian to require an order of magnitude larger sample than simple Gaussian statistics would indicate. The requirements increase from this baseline if non-Gaussian photometry errors are included. Again the impact can be mitigated by incorporating the correct noise model, but only to the equivalent of a survey with much larger Gaussian photometry errors. However, these requirements may well be overestimates because they are based on a need to know the rms, which is particularly sensitive to tails. Other parametrizations of the distribution may require smaller samples.

Notes: —Only a single specimen of the original material is extant in A; the duplicate in PNH must have been destroyed during World War II. Merrill (1917a) mentioned that the type material of his Bornean species were deposited in PNH. Although Chen et al. (2015) correctly stated that the holotype in PNH was destroyed, a lectotypification was not performed. Therefore, we here designate the A sheet as lectotype.

description: The Wide-field Infrared Transient Explorer (WINTER) is a 1x1 degree infrared survey telescope under development at MIT and Caltech, and slated for commissioning at Palomar Observatory in 2021. WINTER is a seeing-limited infrared time-domain survey and has two main science goals: (1) the discovery of IR kilonovae and r-process materials from binary neutron star mergers and (2) the study of general IR transients, including supernovae, tidal disruption events, and transiting exoplanets around low mass stars. We plan to meet these science goals with technologies that are relatively new to astrophysical research: hybridized InGaAs sensors as an alternative to traditional, but expensive, HgCdTe arrays and an IR-optimized 1-meter COTS telescope. To mitigate risk, optimize development efforts, and ensure that WINTER meets its science objectives, we use model-based systems engineering (MBSE) techniques commonly featured in aerospace engineering projects. Even as ground-based instrumentation projects grow in complexity, they do not often have the budget for a full-time systems engineer. We present one example of systems engineering for the ground-based WINTER project, featuring software tools that allow students or staff to learn the fundamentals of MBSE and capture the results in a formalized software interface. We focus on the top-level science requirements with a detailed example of how the goal of detecting kilonovae flows down to WINTER's optical design. In particular, we discuss new methods for tolerance simulations, eliminating stray light, and maximizing image quality of a fly's-eye design that slices the telescope's focus onto 6 non-buttable, IR detectors. We also include a discussion of safety constraints for a robotic telescope.
