description: We present a case study on a new type of cold neutron beam station for the investigation of angular correlations in the beta-decay of free neutrons. With this beam station, called PERC, the 'active decay volume' lies inside the neutron guide, and the charged neutron decay products are magnetically guided towards the end of the neutron guide. Hence, the guide delivers at its exit a beam of decay electrons and protons, under well-defined and precisely variable conditions, which can be well separated from the cold neutron beam. In this way a general-purpose source of neutron decay products is obtained which can be used for various different experiments in neutron decay correlation spectroscopy. A gain in phase space density of several orders of magnitude can be achieved with PERC, as compared to existing neutron decay spectrometers. Neutron beam related background is separately measurable in PERC, and magnetic mirror effects on the charged neutron decay products and edge effects in the active neutron beam volume are both strongly suppressed. Therefore the spectra and angular distributions of the emerging decay particles will be distortion-free on the level of 10^-4, more than 10 times better than achieved today.

description: The five planets discovered around the main-sequence star 55 Cnc may represent a case of stable chaos. By using both the Frequency Map Analysis and MEGNO we find that about 15 % of the systems that can be build from the nominal orbital elements of the system are highly chaotic. However, in spite of the fast diffusion rate in the phase space, the planetary system is not destabilized over 400 Myr and close encounters between the planets are avoided.

description: The move of propaganda and disinformation to the online environment is possible thanks to the fact that within the last decade, digital information channels radically increased in popularity as a news source. The main advantage of such media lies in the speed of information creation and dissemination. This, on the other hand, inevitably adds pressure, accelerating editorial work, fact-checking, and the scrutiny of source credibility. In this chapter, an overview of computer-supported approaches to detecting disinformation and manipulative techniques based on several criteria is presented. We concentrate on the technical aspects of automatic methods which support fact-checking, topic identification, text style analysis, or message filtering on social media channels. Most of the techniques employ artificial intelligence and machine learning with feature extraction combining available information resources. The following text firstly specifies the tasks related to computer detection of manipulation and disinformation spreading. The second section presents concrete methods of solving the tasks of the analysis, and the third sections enlists current verification and benchmarking datasets published and used in this area for evaluation and comparison.

description: We study finiteness conditions on large tilting modules over arbitrary rings. We then turn to a hereditary artin algebra R and apply our results to the (infinite dimensional) tilting module L that generates all modules without preprojective direct summands. We show that the behaviour of L over its endomorphism ring determines the representation type of R. A similar result holds true for the (infinite dimensional) tilting module W that generates the divisible modules. Finally, we extend to the wild case some results on Baer modules and torsion-free modules proven in [AHT] for tame hereditary algebras.

description: Situated in a higher education institution in the UAE, this thesis explores the changes educators went through as they started the practice of teaching during a pandemic. Although the practice is bound to change in response to many variables, it is crucial that the initial stages of the practice are investigated and critically analyzed. Such an analysis can facilitate a better understanding of its development and allow researchers and educators in the future to situate this growing practice of teaching during a pandemic. This study aims to provide a localized historical foundation for the practice of teaching during a pandemic from the perspective of higher education teachers. Based on a critical realist stance, this research utilized Cultural-Historical Activity Theory as a guiding framework. Data for the study were collected at three points: March 2019, March 2020, and May 2020. Having interviewed the participants a year before the pandemic made it possible for the study to historically (and locally) situate participants' instructional practices and allowed for highlighting the unique effects of pandemic-induced tensions and changes. Utilizing Activity Systems Analysis, results discuss the tensions that developed in response to the need to stay safe during the pandemic while, at the same time, meeting the instructional needs of remote teaching and learning. Many changes happened, and nearly all aspects of the system had to change or develop somehow to sustain the activity of teaching. Results from this study can inform several layers of the community who are interested in higher education, technology-mediated teaching, remote teaching, and the effects of the pandemic on the activity of teaching.

description: The aim of the present article is to analyse the publication „Modulare Architektur der menschlichen Sprachfähigkeit” by Barbara Sadownik, a professor of German at the University of Lublin. How is language represented mentally and neuronally? What processes take place in our minds when we produce and receive language, i.e., how do we acquire language? These questions about the nature of language ability, as well as the structure and function of language are central to interdisciplinary research in humanities and the natural sciences. The leitmotifs of this publication are modularity and holism, with the historical foray indicating that modularity, in particular, is to be taken as the key to understanding the architecture of human linguistic ability

description: We present the main features of the solution of the gravitino and dilatino Killing spinor equations derived in hep-th/0510176 and hep-th/0703143 which have led to the classification of geometric types of all type I backgrounds. We then apply these results to the supersymmetric backgrounds of the heterotic string. In particular, we solve the gaugino Killing spinor equation together with the other two Killing spinor equations of the theory. We also use our results to classify all supersymmetry conditions of ten-dimensional gauge theory.

The Survival of Multiphase Dusty Clouds in Hot Winds

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Much progress has been made recently in the acceleration of $\sim10^{4}$\,K clouds to explain absorption-line measurements of the circumgalactic medium and the warm, atomic phase of galactic winds. However, the origin of the cold, molecular phase in galactic winds has received relatively little theoretical attention. Studies of the survival of $\sim10^{4}$\,K clouds suggest efficient radiative cooling may enable the survival of expelled material from galactic disks. Alternatively, gas colder than 10$^4$\,K may form within the outflow, including molecules if dust survives the acceleration process. We explore the survival of dusty clouds in a hot wind with three-dimensional hydrodynamic simulations including radiative cooling and dust modeled as tracer particles. We find that cold $\sim10^{3}$\,K gas can be destroyed, survive, or transformed entirely to $\sim 10^4\,$K gas. We establish analytic criteria distinguishing these three outcomes which compare characteristic cooling times to the system's `cloud crushing' time. In contrast to typically studied $\sim10^{4}$\,K clouds, colder clouds are entrained faster than the drag time as a result of efficient mixing. We find that while dust can in principle survive embedded in the accelerated clouds, the survival fraction depends critically on the time dust spends in the hot phase and on the effective threshold temperature for destruction. We discuss our results in the context of polluting the circumgalactic medium with dust and metals, as well as understanding observations suggesting rapid acceleration of molecular galactic winds and ram pressure stripped tails of jellyfish galaxies.

description: In the work of male poets, the love for a woman is often a pretext for the elaboration of their texts; that love can be seen both as a deeply felt personal inspiration and as the point of origin for stylistic adventures, which involve the less personal techniques of poetic art. The figure of the feminine poetic beloved abounds in the lyric tradition as muse, far-off or lost love, or cold-hearted belle dame sans merci; as the idealization of an idea of Woman, as imagined interlocutor, or as a symbol of something that transcends an embodied female presence; and it is typically read as one of a pair — the poet who loves and the feminine figure who is loved. It is thus that we think of Dante and Beatrice, Petrarch and Laura, Montale and Clizia. In these emblematic poetic couples the lady love is transcendent; in simple terms, she is dead and gone, or merely gone, and exists on a higher plane than that on which the yearning poet struggles to live and to find expression equal to her resplendence, moved by her absence to create the presence of poetry.

description: In dieser Dissertation werden Quantenkorrekturen zu Higgs Boson Massen in dem ladungs- und paritätsverletzenden Nicht-Minimalen Supersymmetrischen Standardmodell auf Zweischleifenordnung berechnet. Der Fokus dieser Arbeit liegt auf jenen Korrekturen, welche ausschließlich im nicht-minimalen nicht aber im Minimalen Supersymmetrischem Standard modell auftreten. Diese Beträge sind deshalb interessant, weil die korrigierten Higgs Boson Massen Einfluss auf Vorhersagen haben können, welche experimentell an Teilchenbeschleunigern getestet werden. Daher können die Higgsmassenkorrekturen die Aussicht auf eine Entdeckung des betrachteten Modells beeinflussen. Des Weiteren können die hier vorgestellten Korrekturen auch für zukünftige Untersuchungen anderer Modelle von Interesse sein. Der Grund dafür ist das Auftreten von (infra-rot) Divergenzen, welche nicht für derartige Berechnungen in minimalen Modellen üblich sind. Die verschiedenen Lösungen für dieses Problem, welche in dieser Arbeit studiert werden, können daher auch in anderen nicht-minimalen Modellrechnungen angewandt werden. Darüber hinaus macht diese Arbeit Aussagen über die Genauigkeit der störungstehorischen Resultate zu den Higgs Boson Massen unter Zuhilfenahme der Abhängigkeit derselbigen von der Wahl des Renormierungsschemata und der Renormierungsskala. Insbesondere werden gemischte OS/DR Renormierungsschemata im Higgs Boson Sektor aber auch im top/stop Sektor der Theorie angewandt. Es wird gezeigt, dass die relativen Korrekturen bis zu 6% groß werden können. In dem Bereich des Modells, welcher mit Unitarität unterhalb der Skala an der sich die Eichkopplungen treffen kompatibel ist, sind die Korrekturen jedoch nicht größer als 3%. Des Weiteren beträgt die theoretische Unsicherheit abgeleitet aus der Variation des Renormierungsschematas in etwa 1-8% und die abgeleitet aus der Renormierungsskala in etwa 0-3%.

description: Recent breakthroughs in bulk crystal growth of the thermodynamically stable beta phase of gallium oxide ($β$-Ga$_2$O$_3$) have led to the commercialization of large-area beta-Ga$_2$O$_3$ substrates with subsequent epitaxy on (010) substrates producing high-quality films. Still, metal-organic chemical vapor deposition (MOCVD), molecular beam epitaxy (MBE), and processing of the (010) $β$-Ga$_2$O$_3$ surface are known to form sub-nanometer scale facets along the [001] direction as well as larger ridges with features perpendicular to the [001] direction. A density function theory calculation of the (010) surface shows an ordering of the surface as a sub-nanometer-scale feature along the [001] direction. Additionally, the general crystal structure of $β$-Ga$_2$O$_3$ is presented and recommendations are presented for standardizing (010) substrates to account for and control the larger-scale ridge formation.

description: Bulk glass formation occurs over a very small part of phase space, and "good" glasses (which form even at low quench rates ~ 10K/sec) select an even smaller part of that accessible phase space. An axiomatic theory provides the physical basis of glass formation, and identifies these sweet spots of glass formation with existence of rigid but stress-free networks for which experimental evidence is rapidly emerging. Recently, theory and experiment have come together to show that these sweet spots of glass formation occur over a range of chemical compositions identified as Intermediate Phases. These ranges appear to be controlled by elements of local and medium range molecular structures that form isostatically rigid networks. Intermediate Phase glasses possess non-hysteretic glass transitions (Tgs) that do not age much. Raman scattering has played a pivotal role in elucidating molecular structure of glasses in general, and in identifying domains of Intermediate Phases. Experiments reveal these phases to possess sharp phase boundaries and to be characterized by an optical elasticity that varies with network mean coordination number, r, as power-law. In this review, we provide examples in chalcogenide and oxide glass systems where these phases along with optical elasticity power-laws have been established. Intermediate Phase glasses represent self-organized nanostructured functional materials optimized by nature.

description: First-price auctions have largely replaced traditional bidding approaches based on Vickrey auctions in programmatic advertising. As far as learning is concerned, first-price auctions are more challenging because the optimal bidding strategy does not only depend on the value of the item but also requires some knowledge of the other bids. They have already given rise to several works in sequential learning, many of which consider models for which the value of the buyer or the opponents' maximal bid is chosen in an adversarial manner. Even in the simplest settings, this gives rise to algorithms whose regret grows as $\sqrt{T}$ with respect to the time horizon $T$. Focusing on the case where the buyer plays against a stationary stochastic environment, we show how to achieve significantly lower regret: when the opponents' maximal bid distribution is known we provide an algorithm whose regret can be as low as $\log^2(T)$; in the case where the distribution must be learnt sequentially, a generalization of this algorithm can achieve $T^{1/3+ ε}$ regret, for any $ε>0$. To obtain these results, we introduce two novel ideas that can be of interest in their own right. First, by transposing results obtained in the posted price setting, we provide conditions under which the first-price biding utility is locally quadratic around its optimum. Second, we leverage the observation that, on small sub-intervals, the concentration of the variations of the empirical distribution function may be controlled more accurately than by using the classical Dvoretzky-Kiefer-Wolfowitz inequality. Numerical simulations confirm that our algorithms converge much faster than alternatives proposed in the literature for various bid distributions, including for bids collected on an actual programmatic advertising platform.

description: We present new results from our survey of diffuse O VI-emitting gas in the interstellar medium with the Far Ultraviolet Spectroscopic Explorer (FUSE). Background observations obtained since 2005 have yielded eleven new O VI detections of 3-sigma significance, and archival searches have revealed two more. An additional 15 sight lines yield interesting upper limits. Combined with previous results, these observations reveal the large-scale structure of the O VI-bearing gas in the quadrant of the sky centered on the Magellanic Clouds. The most prominent feature is a layer of low-velocity O VI emission extending more than 70 degrees from the Galactic plane. At low latitudes (|b| < 30 degrees), the emission comes from narrow, high-density conductive interfaces in the local ISM. At high latitudes, the emission is from extended, low-density regions in the Galactic halo. We also detect O VI emission from the interface region of the Magellanic System, a structure recently identified from H I observations. These are the first detections of emission from high-ionization species in the Magellanic System outside of the Clouds themselves.

description: Due to an extremely rugged structure of the free energy landscape, the determination of spin-glass ground states is among the hardest known optimization problems, found to be NP-hard in the most general case. Owing to the specific structure of local (free) energy minima, general-purpose optimization strategies perform relatively poorly on these problems, and a number of specially tailored optimization techniques have been developed in particular for the Ising spin glass and similar discrete systems. Here, an efficient optimization heuristic for the much less discussed case of continuous spins is introduced, based on the combination of an embedding of Ising spins into the continuous rotators and an appropriate variant of a genetic algorithm. Statistical techniques for insuring high reliability in finding (numerically) exact ground states are discussed, and the method is benchmarked against the simulated annealing approach.

description: We review the current status and recent progress of microscopic many-body approaches and phenomenological models, which are employed to construct the equation of state of neutron stars. The equation of state is relevant for the description of their structure and dynamical properties, and it rules also the dynamics of core-collapse supernovae and binary neutron star mergers. We describe neutron star matter assuming that the main degrees of freedom are nucleons and hyperons, disregarding the appearance of quark matter. We compare the theoretical predictions of the different equation-of-state models with the currently available data coming from both terrestrial laboratory experiments and recent astrophysical observations. We also analyse the importance of the nuclear strong interaction and equation of state for the cooling properties of neutron stars. We discuss the main open challenges in the description of the equation of state, mainly focusing on the limits of the different many-body techniques, the so-called "hyperon puzzle," and the dependence of the direct URCA processes on the equation of state.

As an evaluation method, user simulation allows us to tackle issues such as scalability and cost-efficiency, making it a viable choice for large-scale automatic evaluation. To help build a human-like user simulator that can measure the quality of a dialogue, we propose the following task: simulating user satisfaction for the evaluation of task-oriented dialogue systems. The purpose of the task is to increase the evaluation power of user simulations and to make the simulation more human-like. To overcome a lack of annotated data, we propose a user satisfaction annotation dataset, USS, that includes 6,800 dialogues sampled from multiple domains, spanning real-world e-commerce dialogues, task-oriented dialogues constructed through Wizard-of-Oz experiments, and movie recommendation dialogues. All user utterances in those dialogues, as well as the dialogues themselves, have been labeled based on a 5-level satisfaction scale. We also share three baseline methods for user satisfaction prediction and action prediction tasks. Experiments conducted on the USS dataset suggest that distributed representations outperform feature-based methods. A model based on hierarchical GRUs achieves the best performance in in-domain user satisfaction prediction, while a BERT-based model has better cross-domain generalization ability.

Optical detection of paramagnetic and cyclotron resonance in semiconductors
Creators: name: Booth, Ian
Publisher: name: University of British Columbia

description: Optical Detection of Magnetic Resonance (ODMR) has been used to observe both paramagnetic and diamagnetic resonance of photo-excited electrons and holes in GaP, ZnTe and AgBr. Paramagnetic resonance of conduction electrons in GaP has been studied and the microwave frequency and power dependence of the effect analysed. The maximum signal strength was observed to produce approximately 1% change in luminescence at 1.6 K. The g value deduced from the resonance was 2.000 ± 0.005. The resonance was homogeneously broadened giving the electron lifetime as approximately 4 nanoseconds. Paramagnetic resonance of electrons and holes has also been detected in AgBr. The background signals present in ODMR experiments have been investigated and are shown to be caused by diamagnetic or cyclotron resonance heating of photoexcited carriers. Measurements at microwave frequencies of 9.2 and 36.3 GHz have been made on GaP,ZnTe and AgBr, and cyclotron resonance of electrons and holes observed. The effective masses of light and heavy holes in GaP were found to be 0.154 ± 0.01 and 0.626 ± 0.06 respectively while the electron effective mass was 0.36 ± 0.10. The electron scattering time was shorter than that for holes by a factor of approximately three, most likely due to scattering by isoelectronic nitrogen impurities. Resonances were observed in ZnTe at effective mass values of 0.30 ± 0.20 and 0.76 ± 0.20 corresponding to electrons and heavy holes. In both GaP and ZnTe resonances due to electrons and holes appeared in different luminescence bands indicating the sensitivity of different recombination centres to heating of either carrier type. Cyclotron resonance of electrons and holes was also observed in AgBr and showed the effects of conduction and valence band non-parabolicity. A feature in the electron resonance indicated enhanced trapping of electrons with certain energies by emission of one or more LO phonons.

description: We are celebrating thirty-years from the seminal papers from Weinberg proposing to use the rules of Chiral Perturbation Theory to nucleon systems. His proposal was to build an Effective Field Theory (EFT) with Chiral symmetry as a key property. A big effort on this line have been made during these three decades, however the issue of renormalization of the theory is not settled. I will briefly review my path on this issue and give my personal view.

description: Non-reversing relaxation enthalpies (DHnr) at glass transitions Tg(x) in the PxGexSe1-2x ternary display wide, sharp and deep global minima (~ 0) in the 0.09 < x < 0.145 range, within which Tgs become thermally reversing. In this reversibility window, glasses are found not to age, in contrast to aging observed for fragile glass compositions outside the window. Thermal reversibility and lack of aging seem to be paradigms of self-organization which molecular glasses share with protein structures which repetitively and reversibly change conformation near Tg and the folding temperature respectively.
A model liquid crystal cell in an RC circuit

description: A nematic liquid-crystal cell subject to an electric field created by electrodes held at constant potential is modeled as a variable capacitor in an RC circuit. The state of the system is characterized in terms of the director field in the cell and the charge on the electrodes. A dynamical system is developed that couples director dynamics in the cell (with no fluid flow) and charge dynamics in the circuit. The dynamical equations are derived from expressions for the total potential energy of the system and a dissipation involving a single rotational viscosity for the director plus Joule heating associated with current in the circuit. An effort is made to quantify effects, in particular the widely differing time scales for the processes involved, and numerical illustrations are given. The exercise illuminates aspects of the modeling of equilibrium states of such a system.

description: High-precision tests of local Lorentz invariance, via monitoring of the sidereal time variation of the photon energies emitted by ultrarelativistic heavy-ion beams and of the beam momentum, are proposed. This paper includes descriptions of the physics ideas and the concept for the detector. The experiment results will allow high-precision tests of LLI via anisotropy of the maximum attainable speed of a photon and an ion. The projected accuracy for the asymmetries interpreted in the framework of the anisotropic relativistic mechanics corresponds to the limit on sidereal time variation of the one-way maximum attainable speed at the levels between $10^{-14}$ and $10^{-17}$.

description: Muons, as a bulk probe of materials, have been used to study the depth profile of charge carrier kinetics in Si wafers by scanning the muon implantation depth. The photoexcited muon spin spectroscopy technique can optically generate excess carriers in semiconductor wafers, while muons can measure the excess carrier density. As a result, carrier recombination lifetime spectra can be obtained. The depth-dependent lifetime spectra enable us to accurately measure the bulk carrier lifetime and surface recombination velocity by fitting the spectra to a simple 1-dimensional diffusion model. Unlike other traditional lifetime spectroscopy techniques, the bulk and surface recombination properties can be readily de-convoluted in this method. Here, we have applied the technique to study silicon wafers both with and without passivation treatment, and have demonstrated that the model can correctly describe the carrier kinetics in these two cases.

First-principles wavevector- and frequency-dependent exchange-correlation kernel for jellium at all densities

description: We propose a spatially and temporally nonlocal exchange-correlation (xc) kernel for the spin-unpolarized fluid phase of ground-state jellium, for use in time-dependent density functional and linear response calculations. The kernel is constructed to satisfy known properties of the exact xc kernel, to accurately describe the correlation energies of bulk jellium, and to satisfy frequency-moment sum rules at a wide range of bulk jellium densities, including those low densities that display strong correlation and symmetry breaking. These effects are easier to understand in the simple jellium model than in real systems. All exact constraints satisfied by the recent MCP07 kernel [A. Ruzsinszky, et al., Phys. Rev. B 101, 245135 (2020)] are maintained in the new revised MCP07 (rMCP07) kernel, while others are added. The revision $f_\mathrm{xc}^\mathrm{rMCP07}(q,ω)$ differs from MCP07 only for non-zero frequencies $ω$. Only at densities much lower than those of real bulk metals is the frequency dependence of the kernel important for the correlation energy of jellium. As the wavevector $q$ tends to zero, the kernel has a $-4πα(ω)/q^2$ divergence whose frequency-dependent ultranonlocality coefficient $α(ω)$ vanishes in jellium, and is predicted by rMCP07 to be extremely small for the real metals Al and Na.}

Exploring Food Webs: Kelp, Otters, and Urchins
Creators: name: Pollak, Tania
Publisher: name: QUBES Educational Resources
Year: 2025

description: This activity is designed to highlight the role of photosynthetic organisms (primary producers) in food webs, predator/prey interaction and energy flow through a system, with a case study involving trophic cascades. The goal is for students who have minimal to no background (beyond maybe an elementary school level) to broaden their appreciation of the role of plants (the course is a plant science course) in a larger ecological context.

After a lecture introducing trophic levels, key terminology, and energy flow through food webs, students develop a simplified aquatic food chain (sea otter, sea urchin, kelp, and fish). Through images of kelp forests, students reflect on what a “healthy” kelp forest looks like. Students then predict the effect of removal of one of the organisms (sea otter) from the food web. Using images of healthy kelp forests and urchin barrens, students then compare what differences they see. A link to a brief video and article further illustrates the value of kelp forests and the interactions and intricacies of an ecosystem.

description: Single electron transistors (SETs) are fabricated by placing single walled carbon nanotubes (SWNTs) on a 100 nm wide local Al/Al2O3 bottom gate and then contacting with Pd electrodes. Coulomb oscillations up to 125 K were observed and charging energies of 12-15 meV with level spacing of ~5 meV were measured from the Couloumb diamond, in agreement with a dot size of ~100 nm, implying that the local gate defines the dot size by bending SWNT at the edges and controls its operation. This "mechanical template" approach may facilitate large scale fabrication of SET devices using SWNT.

description: We consider actions of reductive groups on a varieties with finitely generated Cox ring, e.g., the classical case of a diagonal action on a product of projective spaces. Given such an action, we construct via combinatorial data in the Cox ring all maximal open subsets such that the quotient is quasiprojective or embeddable into a toric variety. As applications, we obtain an explicit description of the chamber structure of the linearized ample cone and several Gelfand-MacPherson type correspondences relating quotients of reductive groups to quotients of torus actions. Moreover, our approach provides information on the geometry of many of the resulting quotient spaces.
