description: We consider the long term evolution of debris following the tidal disruption of compact stars in the context of short gamma ray bursts (SGRBs). The initial encounter impulsively creates a hot, dense, neutrino-cooled disk capable of powering the prompt emission. After a long delay, we find that powerful winds are launched from the surface of the disk, driven by the recombination of free nucleons into alpha particles. The associated energy release depletes the mass supply and eventually shuts off activity of the central engine. As a result, the luminosity and mass accretion rate deviate from the earlier self-similar behavior expected for an isolated ring with efficient cooling. This then enables a secondary episode of delayed activity to become prominent as an observable signature, when material in the tidal tails produced by the initial encounter returns to the vicinity of the central object. The time scale of the new accretion event can reach tens of seconds to minutes, depending on the details of the system. The associated energies and time scales are consistent with those occurring in X-ray flares.

description: The precise programming of crossbar arrays of unit-cells is crucial for obtaining high matrix-vector-multiplication (MVM) accuracy in analog in-memory computing (AIMC) cores. We propose a radically different approach based on directly minimizing the MVM error using gradient descent with synthetic random input data. Our method significantly reduces the MVM error compared with conventional unit-cell by unit-cell iterative programming. It also eliminates the need for high-resolution analog-to-digital converters (ADCs) to read the small unit-cell conductance during programming. Our method improves the experimental inference accuracy of ResNet-9 implemented on two phase-change memory (PCM)-based AIMC cores by 1.26%.

description: We present the observation of a charge-sign dependent solar modulation of galactic cosmic rays (GCRs) with the CALorimetric Electron Telescope onboard the International Space Station over 6 yr, corresponding to the positive polarity of the solar magnetic field. The observed variation of proton count rate is consistent with the neutron monitor count rate, validating our methods for determining the proton count rate. It is observed by the CALorimetric Electron Telescope that both GCR electron and proton count rates at the same average rigidity vary in anticorrelation with the tilt angle of the heliospheric current sheet, while the amplitude of the variation is significantly larger in the electron count rate than in the proton count rate. We show that this observed charge-sign dependence is reproduced by a numerical ``drift model'' of the GCR transport in the heliosphere. This is a clear signature of the drift effect on the long-term solar modulation observed with a single detector.

description: The idea of connecting a natural phenomenon to a form of writing – a romantic idea – has always been a target of men of science, before and after romanticism. Despite a long series of attempts, which failed more in their technological substance (– how can the acoustic phenomenon be represented? –) than in their depicting quality (– which are the characteristics of the acoustic phenomenon given back the depic- tion? –) or, better, in spite of the dialectic of the two questions, tran-scribing acoustical phenomenon is still a matter of study. Representing the signal is a problem that still involves scholars. It could be interesting to notice that, also in this field, the research oscillates between ‘discrete’ world (to represent musical notes) and ‘continuous’ world (to represent the physical phenomenon). The knowledge of the technological system that produced a sound document (we could even speak of document in general) allows a correct reading, although the stated aim it is not enough. As all operations we nowadays carry out take place in the digitale quantized domain, a re-mediation is necessary. This re-mediation allows the production of the original document in a new form, easy to manipulate. Throughout the conversion from ‘analogic’ to ‘digital’ a change in paradigm happens and this change is necessary to produce the transcription which is the final purpose of this work. While working in the sole flow of bits, we can ‘freely’ process information and give them back into various different forms among which the graphical form is one of the possible expressions. The interest for the «sound writing» topic is witnessed by the increased use of the most various forms of sound representation/depiction and by numerous web sites. Among the websites I would like to mention the one edited by William Burdette, soundwriting.org, devoted «to explore the intersections of audio recording and writing», that does not accepts only academic experiences, and the web site of historical contents by Victor Jones, Sound Visualization and Analysis in the Pre-Electronic Era -Visualization. A case study ends this work. The magnetic tape E20, from the RAI Studio di Fonologia Musicale Archive in Milano (Italy), carrying the electronic part of Hyperion by Bruno Maderna, is transcribed under a graphical form to be analyzed and to be collated with other works by the italian musician.

description: We investigate the Josephson effect through a two-level quantum dot with an exchange coupling between two dot electrons. We compute the superconducting phase relationship and construct the phase diagram in the superconducting gap--exchange coupling plane in the regime of the singlet-triplet transition driven by the exchange coupling. In our study two configurations for the dot-lead coupling are considered: one where effectively only one channel couples to the dot, and the other where the two dot orbitals have opposite parities. Perturbative analysis in the weak-coupling limit reveals that the system experiences transitions from 0 to $π$ (negative critical current) behavior, depending on the parity of the orbitals and the spin correlation between dot electrons. The strong coupling regime is tackled with the numerical renormalization group method, which first characterizes the Kondo correlations due to the dot-lead coupling and the exchange coupling in the absence of superconductivity. In the presence of superconductivity, many-body correlations such as two-stage Kondo effect compete with the superconductivity and the comparison between the gap and the relevant Kondo temperature scales allows to predict a rich variety of phase diagrams for the ground state of the system and for the Josephson current. Numerical calculations predicts that our system can exhibit Kondo-driven 0-$π$-0 or $π$-0-$π$ double transitions and, more interestingly, that if proper conditions are met a Kondo-assisted $π$-junction can arise, which is contrary to a common belief that the Kondo effect opens a resonant level and makes the 0-junction. Our predictions could be probed experimentally for a buckminster fullerene sandwiched between two superconductors.

description: We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou~5. Low-resolution spectra obtained during the primary eclipse -- to our knowledge the first isolated spectra of the companion to a post-common-envelope planetary nebula central star -- were compared to catalogue spectra, indicating that the companion star is a late K- or early M-type dwarf. Simultaneous modelling of multi-band photometry and time-resolved radial velocity measurements was then used to independently determine the parameters of both stars as well as the orbital period and inclination. The modelling indicates that the companion star is low mass ($\sim$0.25~M$_\odot$) and has a radius significantly larger than would be expected for its mass. Furthermore, the effective temperature and surface gravity of nebular progenitor, as derived by the modelling, do not lie on single-star post-AGB evolutionary tracks, instead being more consistent with a post-RGB evolution. However, an accurate determination of the component masses is challenging. This is principally due to the uncertainty on the locus of the spectral lines generated by the irradiation of the companion's atmosphere by the hot primary (used to derive companion star's radial velocities), as well as the lack of radial velocities of the primary.

description: We have observed the Josephson effect in junctions formed between single crystals of SrFe1.74Co0.26As2 and Ba0.23K0.77Fe2As2. I-V curves showed resistively-shunted junction characteristics, and the ac Josephson effect was observed under microwave irradiation. By applying an in-plane magnetic field, the critical current is completely modulated and shows a relatively symmetric diffraction pattern, consistent with the intermediate junction limit. The observation of the Josephson effect in the p-n bicrystal structure not only has significant implications for designing phase-sensitive junctions to probe the pairing symmetry of iron pnictide superconductors, but also represents an important step in developing all iron pnictide devices for applications.

description: In this paper, we propose an optimal but low-complexity optimization method for nonsquare differential massive MIMO. While a discrete nonlinear optimization is required for the conventional nonsquare differential coding, we newly modify it to perform a low-complexity continuous linear optimization. This novel method exhibits immediate convergence as compared to the conventional method. Additionally, the proposed differential coding can be regarded as a differential counterpart of the coherent generalized spatial modulation. Our numerical comparisons demonstrate that the proposed method achieves the best coding gain for any number of transmit antennas, although the optimization cost is nearly negligible.

description: We present a new procedure for the construction of parabolic mirrors using low cost materials. We build a spinning system composed of nylon threads, fish hooks and a plastic bucket. We pour liquid plaster into the bucket and set it in constant rotational motion relative to the earth. A liquid substance assumes a parabolic profile when spinning at constant angular velocity relative to an inertial frame under the influence of an uniform vertical gravitational field. By keeping the bucket under rotation for a long time, the plaster solidifies into a parabolic format. We utilize this solidified plaster paraboloid as a model to construct a counter-mould of glass fibre and resin. Over this counter-mould it is placed stretched laminated foil and then it is poured thick plaster over it. In this way it is obtained a parabolic mirror made of laminated foil and plaster. Our only objective here is to present a new method for the construction of parabolic mirror using low cost materials. This allows further exploration of this procedure by teachers and students either in high-schools or in universities.

description: Tissue-resident macrophage (TRM) is crucial for organ development and homeostasis. Tissue-specific functions of different TRM subpopulations and their role in cancer remain unclear. Using single-cell RNA sequencing, we report a previously unidentified TRM subpopulation characterized by VSIG4 overexpression in normal testis and testicular cancer. In a broader view, we further found that this subpopulation is also present in patients with liver hepatocellular carcinoma, lung carcinoma, and glioblastoma, and is associated with suppressed CD8+ T-cell immunity or poor prognosis in 4 independent cohorts. Mechanistically, we demonstrated that VSIG4+ TRM subcluster can directly inhibit the expression of IFN-Gamma, TNF-Alpha, and IL-2 in CD8+ T cells, while MEF2C is the key transcription factor that maintains the existence and function of this subset. In the preclinical models, by using MEF2C inhibitor, knockout VSIG4 in macrophages, or combination with anti-VSIG4 significantly enhances immunotherapy efficacy.

description: Wind-blown sand, or 'saltation,' creates sand dunes, erodes geological features, and could be a significant source of dust aerosols on Mars. Moreover, the electrification of sand and dust in saltation, dust storms, and dust devils could produce electric discharges and affect atmospheric chemistry. We present the first calculations of electric fields in martian saltation, using a numerical model of saltation that includes sand electrification, plasma physics, and the adsorption of ions and electrons onto particulates. Our results indicate that electric discharges do not occur in martian saltation. Moreover, we find that the production of hydrogen peroxide and the dissociation of methane by electric fields are less significant than previously thought. Both these species are highly relevant to studies of past and present life on Mars.

Tennyson and the concept of evolution in Victorian poetry before 1859
Creators: name: Elliott, William Brent
Publisher: name: University of British Columbia
Year: 2010

description: This thesis attempts to examine the use of pre-Darwinian evolutionary concepts in Victorian poetry by concentrating on the works of Tennyson, who gave fuller expression to them than any of his contemporaries. Works by other poets are examined for significant comparisons and contrasts with his; various works by Browning, Bailey, Arnold, and Bell Scott receive particular attention. The introduction distinguishes between Darwin's theory and pre-Darwinian evolutionary schemes, finding the latter to be characterized by the notions of teleology, progressivism, and vertical hierarchy. The historical development of evolutionism is traced from its origins in Romantic theories of the organic unity of nature, and the major varieties of considered positions on the subject available to a poet in the early nineteenth century are enumerated. Tennyson's early work is shown to develop from a basically static, non-evolutionary world-picture to a progressive one, making use of images of development drawn from embryology, astronomy, and reincarnation. The stages of composition of In Memoriam reveal the impact of Lyell, who emphasized the struggle for existence and necessary extinction, and later of Chambers, who proposed a concept of the progressive transformation of species. It is proposed that Tennyson found in Chambers' theory a way of transcending the bleak world-picture offered by Lyell, by uniting it with his conception of a spiritual reality behind (not immanent in) the material world. The final arrangement of In Memoriam develops the idea of evolution as the progress of the natural world toward the spiritual, a position analogous to a number of poetic and philosophical trends in the early nineteenth century. This process of evolution can be voluntarily aided by "typing" the higher, emergent forms in one's own life. Expanding on this notion, Tennyson's poetry of the late 1340's and 1350's demands the conscious participation of human society in the shaping of a higher being. With this development, Tennyson's philosophy of evolution is substantially complete. His later works reveal a gradual attenuation of his immediate hopes for the process, pushing the improvement of the species into the increasingly distant future, but remaining consistently meliorist; otherwise, his principle continues to be the one set forth in In Memoriam. The study concludes with a brief examination of Darwin's influence on later poets, showing it to have been generally confused and the result of misinterpretation.

description: This study presents our team PathToMyHeart's contribution to the George B. Moody PhysioNet Challenge 2022. Two models are implemented. The first model is a Dual Bayesian ResNet (DBRes), where each patient's recording is segmented into overlapping log mel spectrograms. These undergo two binary classifications: present versus unknown or absent, and unknown versus present or absent. The classifications are aggregated to give a patient's final classification. The second model is the output of DBRes integrated with demographic data and signal features using XGBoost.DBRes achieved our best weighted accuracy of $0.771$ on the hidden test set for murmur classification, which placed us fourth for the murmur task. (On the clinical outcome task, which we neglected, we scored 17th with costs of $12637$.) On our held-out subset of the training set, integrating the demographic data and signal features improved DBRes's accuracy from $0.762$ to $0.820$. However, this decreased DBRes's weighted accuracy from $0.780$ to $0.749$. Our results demonstrate that log mel spectrograms are an effective representation of heart sound recordings, Bayesian networks provide strong supervised classification performance, and treating the ternary classification as two binary classifications increases performance on the weighted accuracy.

description: Approximate analytic expressions for haze (and gloss) of Gaussian randomly rough surfaces for various types of correlation functions are derived within phase-perturbation theory. The approximations depend on the angle of incidence, polarization of the incident light, the surface roughness, $σ$, and the average of the power spectrum taken over a small angular interval about the specular direction. In particular it is demonstrated that haze(gloss) increase(decrease) with $σ/λ$ as $\exp(-A(σ/λ)^2)$ and decreases(increase) with $a/λ$, where $a$ is the correlation length of the surface roughness, in a way that depends on the specific form of the correlation function being considered. These approximations are compared to what can be obtained from a rigorous Monte Carlo simulation approach, and good agreement is found over large regions of parameter space. Some experimental results for the angular distribution of the transmitted light through polymer films, and their haze, are presented and compared to the analytic approximations derived in this paper. A satisfactory agreement is found. In the literature haze of blown polyethylene films has been related to surface roughness. Few authors have quantified the roughness and other have pointed to the difficulty in finding the correct roughness measure.

description: The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino experiment designed to mainly investigate oscillation parameters, supernova physics and proton decay. Its far detector will be composed of four liquid argon time projection chamber (LArTPC) underground modules, in South Dakota-USA, which will detect a neutrino beam produced at Fermilab, 1300 km away, where a near detector will be in place. The second DUNE far detector module, Vertical Drift, will be a single phase LArTPC with electron drift along the vertical axis with two volumes of 13.5 m x 6.5 m x 60 m dimensions separated by a cathode plane. The charge collection will be performed by two anode planes placed at the top and bottom of the module, each composed by stacked layers of a perforated PCB technology with electrode strips. The photon detection system (PDS) will make use of large size X-Arapuca tiles distributed over three detection planes. One plane will consist of a horizontal arrangement of double sided tiles installed on the high voltage cathode plane and two vertical planes, each placed on the longest cryostat membrane walls. A light active coverage of 14.8% over the cathode and 7.4% over the laterals should allow improvements in the low energy physics range that can be probed in DUNE, especially regarding supernova neutrinos (~10 MeV). We present the initial characterization of the Vertical Drift PDS using a Monte Carlo simulation and preliminary studies on its reconstruction capabilities at the MeV scale. The information obtained with the PDS alone should allow determination of a neutrino interaction region with a precision of at least 65 cm for events with deposited energy above 5 MeV and the deposited energy can be reconstructed with precision better than 10%, both at the center of the volume.

description: The Global Wearable market is anticipated to rise at a considerable rate in the next coming years and communication is a fundamental block in any wearable device. In communication, encryption methods are being used with the aid of microcontrollers or software implementations, which are power-consuming and incorporate complex hardware implementation. Internet of Things (IoT) devices are considered as resource-constrained devices that are expected to operate with low computational power and resource utilization criteria. At the same time, recent research has shown that IoT devices are highly vulnerable to emerging security threats, which elevates the need for low-power and small-size hardware-based security countermeasures. Chaotic encryption is a method of data encryption that utilizes chaotic systems and non-linear dynamics to generate secure encryption keys. It aims to provide high-level security by creating encryption keys that are sensitive to initial conditions and difficult to predict, making it challenging for unauthorized parties to intercept and decode encrypted data. Since the discovery of chaotic equations, there have been various encryption applications associated with them. In this paper, we comprehensively analyze the physical and encryption attacks on continuous chaotic systems in resource-constrained devices and their potential remedies. To this aim, we introduce different categories of attacks of chaotic encryption. Our experiments focus on chaotic equations implemented using Chua's equation and leverages circuit architectures and provide simulations proof of remedies for different attacks. These remedies are provided to block the attackers from stealing users' information (e.g., a pulse message) with negligible cost to the power and area of the design.

description: Graphene is considered to be a promising candidate for future nano-electronics due to its exceptional electronic properties. Unfortunately, the graphene field-effect-transistors (FETs) cannot be turned off effectively due to the absence of a bandgap, leading to an on/off current ratio typically around 5 in top-gated graphene FETs. On the other hand, theoretical investigations and optical measurements suggest that a bandgap up to a few hundred meV can be created by the perpendicular E-field in bi-layer graphenes. Although previous carrier transport measurements in bi-layer graphene transistors did indicate a gate-induced insulating state at temperature below 1 Kelvin, the electrical (or transport) bandgap was estimated to be a few meV, and the room temperature on/off current ratio in bi-layer graphene FETs remains similar to those in single-layer graphene FETs. Here, for the first time, we report an on/off current ratio of around 100 and 2000 at room temperature and 20 K, respectively in our dual-gate bi-layer graphene FETs. We also measured an electrical bandgap of >130 and 80 meV at average electric displacements of 2.2 and 1.3 V/nm, respectively. This demonstration reveals the great potential of bi-layer graphene in applications such as digital electronics, pseudospintronics, terahertz technology, and infrared nanophotonics.

description: Compared with traditional face-to-face teaching, online learning is more convenient. However, during online classes, it is more difficult for teachers to observe all student reactions at the same time. Our system is designed to help teachers to adjust the speed of their lessons by detecting student reactions. In this study, we estimate student head pose, hand poses, and expressions through the camera, all these poses will be used as criteria for judging the student participation. After estimating, we proposed a method to evaluate classroom participation based on student head pose, hand poses, and facial expression recognition. The estimated result divides the class quality into positive, neutral, and negative, then, under the help of the system, teachers can rearrange the content of the class.

La storia di quattro reduci: Žažda (Sete) di Andrej Gelasimov
Creators: name: Rossi, Valentina
Publisher: name: Firenze University Press
Year: 2013
Subjects: Russian contemporary prose; Chechnya war; trauma; Gelasimov; Zhazhda

description: Gelasimov’s novel was analysed by Remizova (2003) as a “Study of a Trauma”. Several themes of the povest’ (childhood, invisibility of the traumatic event, social vs. individual mediated responses to trauma) are taken into account, based on the hypothesis that the keywords of the traumatic experience described in Gelasimov’s “report” on the Chechen War are herein emphasized, revealing one of the main levels of meaning in the narration. Against this background Gelasimov’s povest’ Zhahda proves its present historical and literary value.

Physical Problems, Sonic Implications. A discussion of the ethics of preservation treatments and audio recordings
Creators: name: Bradley, Kevin
Publisher: name: Musica/Tecnologia
Year: 2009

description: Conservators have traditionally operated under a particular set of ethical constraints. The AIC code of ethics, for example, states “The conservation professional should only recommend or undertake treatment that is judged suitable to the preservation of the aesthetic, conceptual, and physical characteristics of the cultural property”. However, when treating sound recordings the situation may well arise where a physical treatment will alter the physical characteristics of the audio carrier, though simultaneously restore or improve the ability of the carrier to reproduce the sound it carries. Where does the responsibility of the sound archivist lie? This paper considers some of the ethical issues surrounding treatments of audio recordings and considers just what it is that we are trying to preserve.

description: Light fusion increases the efficiency of solar cells by converting photons with lower energy than the bandgap into higher energy photons. The solar cell converts the product photons to current. We use Monte Carlo simulation to predict that lead sulfide (PbS) quantum dot sensitizers will enable fusion with a figure of merit on the mA cm$^{-2}$ scale, exceeding current records, while enabling silicon cell compatibility. Performance is highly sensitive to quantum dot size, on the order of mA cm$^{-2}$ nm$^{-1}$.

Measurement of $π^{0}$ and $γ$ in d+Au collisions at $\sqrt{s_{NN}}=$ 200 GeV by PHENIX experiment

description: Previous results indicated that high $p_T$ particle suppression in Au+Au interactions is a final state effect, since R$_{dA}$ ratios were compatible with unity, albeit within large experimental errors. It is important to test this conclusion to higher precision since the modification of structure functions may be involved. Recent d+Au data taken in 2008 improve the integrated luminosity by about a factor of thirty compared to the 2003 data. A more precise measurement of both $π^0$ and $γ$ at higher $p_T$ will shed new light on whether the initial state in the heavy nuclei is modified.

subject: FOS: Physical sciences

description: In this work, we study the Benjamin-Bona-Mahony like equations with a fully nonlinear dispersive term by means of the factorization technique. In this way we find the travelling wave solutions of this equation in terms of the Weierstrass function and its degenerated trigonometric and hyperbolic forms. Then, we obtain the pattern of periodic, solitary, compacton and kink-like solutions. We give also the Lagrangian and the Hamiltonian, which are linked to the factorization, for the nonlinear second order ordinary differential equations associated to the travelling wave equations.

description: We consider one aspect of the theoretical foundations of polarization experiments on elastic scattering of electrons on protons yielding form factor ratios incompatible with those that are extracted from nonpolarization experiments. We analyze the consequences of abandoning the assumption that the nucleon is a Dirac particle. We show that the process of elastic scattering of electrons on nucleons is described by the same formulas, irrespective of the proper Lorentz group representation associated with the nucleon as a particle with the rest spin 1/2.

Nuclear level densities away from line of $β$-stability

description: The variation of total nuclear level densities (NLDs) and level density parameters with proton number $(Z)$ are studied around the $β$-stable isotope, $Z_{0}$, for a given mass number. We perform our analysis for a mass range $A=40$ to 180 using the NLDs from popularly used databases obtained with the single-particle energies from two different microsopic mass-models. These NLDs which include microscopic structural effects such as collective enhancement, pairing and shell corrections, do not exhibit inverted parabolic trend with a strong peak at $Z_{0}$ as predicted earlier. We also compute the NLDs using the single-particle energies from macroscopic-microscopic mass-model. Once the collective and pairing effects are ignored, the inverted parabolic trends of NLDs and the corresponding level density parameters become somewhat visible. Nevertheless, the factor that governs the $(Z-Z_{0})$ dependence of the level density parameter, leading to the inverted parabolic trend, is found to be smaller by an order of magnitude. We further find that the $(Z-Z_{0})$ dependence of NLDs is quite sensitive to the shell effects.
