description: We present the development of a single-photon detector and the connected read-out electronics. This `hybrid' detector is based on a vacuum tube, transmission photocathode, microchannel plate and a pixelated CMOS read-out anode encapsulating the analog and digital-front end electronics. This assembly will be capable of detecting up to $10^9$ photons per second with simultaneous measurement of position and time. The pixelated read-out anode used is based on the Timepix4 ASIC ($65~\mathrm{nm}$ CMOS technology) designed in the framework of the Medipix4 collaboration. This ASIC is an array of $512\times448$ pixels distributed on a $55~\mathrm{μm}$ square pitch, with a sensitive area of $\sim 7~\mathrm{cm}^2$. It features $50$-$70~\mathrm{e^{-}}$ equivalent noise charge, a maximum rate of $2.5~\mathrm{Ghits/s}$, and allows to time-stamp the leading-edge time and to measure the Time-over-Threshold (ToT) for each pixel. The pixel-cluster position combined with its ToT information will allow to reach $5$-$10~\mathrm{μm}$ position resolution. This information can also be used to correct for the leading-edge time-walk achieving a timing resolution of the order of $10~\mathrm{ps}$. The detector will be highly compact thanks to the encapsulated front-end electronics allowing local data processing and digitization. An FPGA-based data acquisition board, placed far from the detector, will receive the detector hits using $16$ electro-optical links operated at $10.24~\mathrm{Gbps}$. The data acquisition board will decode the information and store the relevant data in a server for offline analysis. These performance will allow significant advances in particle physics, life sciences, quantum optics or other emerging fields where the detection of single photons with excellent timing and position resolutions are simultaneously required.

description: Wind energy is converted into electric power via wing sails moving on rails. A linear generator/motor is split between the rail and carriage, where the linear stator is integrated in the rail track. Each carriage contains a part of the linear rotor. The acceleration/deceleration of each carriage is controlled by adjusting the electrical power input/output of the converters related to the carriage.

description: Using the light of the sun as the primary source for illuminating offices and houses is one of the most effective ways of saving energy. The problem, which many knows, is that on a sunny summer day, the light may be too intense to be used directly. Reading a book if the rays of the sun hits directly on the pages can be impossible, not to mention the problem of seeing what is happening on the computer screen. By using nanostructured windows it is possible to homogeneously redirect natural light, eliminating the need for using blinds and electric lighting during daytime.
Density Wakes due to Dynamical Friction in Cored Potentials

description: Dynamical friction is often modeled with reasonable accuracy by the widely used Chandrasekhar formula. However, in some circumstances, Chandrasekhar's local and uniform approximations can break down severely. An astrophysically important example is the "core stalling" phenomenon seen in N-body simulations of massive perturber inspiralling into the near-harmonic potential of a stellar system's constant-density core (and possibly also in direct observations of dwarf galaxies with globular clusters). In this paper we use the linearized collisionless Boltzmann equation to calculate the global response of a cored galaxy to the presence of a massive perturber. We evaluate the density deformation, or wake, due to the perturber and study its geometrical structure to better understand the phenomenon of core stalling. We also evaluate the dynamical friction torque acting on perturber from the Lynden-Bell--Kalnajs (LBK) formula. In agreement with past work, we find that the dynamical friction force arising from corotating resonances is greatly weakened, relative to the Chandrasekhar formula, inside a constant density core. In contrast to past work, however, we find that a population of previously neglected high-order and non-corotating resonances sustain a minimum level of frictional torque at ~10 % of the torque from Chandrasekhar formula. This suggests that complete core stalling likely requires phenomena beyond the LBK approach; we discuss several possible explanations. Additionally, to study core stalling for multiple perturbers, we investigate approximate secular dynamical interactions (akin to Lidov-Kozai dynamics) between two perturbers orbiting a cored stellar system and derive a criterion for instability arising due to their close encounters.

description: The calculation of physical quantities in certain quantum field theories such as those of the Argyres-Douglas type is notoriously hard, due to the lack of a Lagrangian description. Here we tackle this problem following two alternative approaches. On the one hand, we use localization on the four-sphere to compute two-correlators and OPE coefficients in Argyres-Douglas superconformal theories. On the other hand, we use the conformal bootstrap machinery to put stringent bounds on such coefficients, only relying on the knowledge of central charge and conformal dimension of the operators. We compare the results obtained with these two methods and find good agreement for all rank-one cases and for the rank-two Argyres-Douglas theories (A_1,A_4) and (A_1,A_5), in the moduli space of pure SU(5) and SU(6) super Yang-Mills. We also apply our results from localization to obtain bounds on the dimensions of the lightest neutral unprotected operators of the CFTs.

Probing charm quark dynamics via multiparticle correlations in PbPb collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV

description: Multiparticle azimuthal correlations of prompt D$^0$ mesons are measured in PbPb collisions at a nucleon-nucleon center-of-mass energy of $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV. For the first time, a four-particle cumulant method is used to extract the second Fourier coefficient of the azimuthal distribution ($v_2$) of D$^0$ mesons as a function of event centrality and the D$^0$ transverse momentum. The ratios of the four-particle $v_2$ values to previously measured two-particle cumulant results provide direct experimental access to event-by-event fluctuations of charm quark azimuthal anisotropies. These ratios are also found to be comparable to those of inclusive charged particles in the event. However, hints of deviations are seen in the most central and peripheral collisions. To investigate the origin of flow fluctuations in the charm sector, these measurements are compared with models implementing fluctuations of charm quark energy loss via collisional or radiative processes in the quark-gluon plasma. These models cannot quantitatively describe the data over the full transverse momentum and centrality ranges, although the calculations with collisional energy loss provide a better description of the data.

description: We construct two and three-line shifts for tree-level amplitude with massless and/or massive particles, and provide a method to construct general multi-line shifts for all masses. We choose the massless-massive BCFW shift from these shifts and examine its validity in renormalizable theories. Using such a shift, we find that amplitudes with at least one massless vector boson are constructible. This reveals the importance of gauge theory in the construction of amplitudes with massive particles. We also find that this kind of amplitudes have a cancellation related to group structure among different channels, which is essential for constructibility. Furthermore, we show that in the limit of large shift parameter $z$, the amplitude with four massive vector bosons, which can include transverse massive vector particles, have structures proportional to the amplitude with shifted vector particles replaced by Goldstone bosons in the leading order. This is responsible for the failure of massive-massive BCFW recursion relations in the amplitudes with four massive vector bosons.

It is unquestionably a different species from L. elusus not only because of its different pronotal sides but also because the collection locality is in lowland rainforest while that of the latter is in highland sclerophyll forest. Since it is a female the opportunity was taken to examine the ovipositor and vaginal sclerite. The ovipositor is without gonostyli (Fig. 26) as in L. monteithi.

description: Fly ash from municipal solid waste incineration (MSWI) is classified as hazardous waste. However, the fly ash has showed pozzolanic behavior, and therefore it has been investigated whether MSWI fly ash may partly substitute cement in Portland cement mortar after upgrading the MSWI fly ash by electrodialytical removal of metals and salts. The influence of MSWI fly ash according to workability, strength and heat evolution has been investigated. It was shown that MSWI fly ash has potential for reuse in Portland cement mortar, which could solve a waste problem and reduce CO2 emissions from the cement industry.

description: We investigate how ferrofluid droplets suspended in a wall-bounded shear flow can organise when subjected to an external magnetic field. By tuning the magnitude of the external magnetic field, we find that the ferrofluid droplets form chain-like structures in the flow direction when the magnetic field is weak, while forming a crystal-like pattern in a strong magnetic field. We provide the phase diagram and the critical conditions for this chain-to-crystal transition, by applying both numerical simulations and analytic calculations. We also examine how the organised patterns of the ferrofluid droplets can be controlled by simply changing the direction of the magnetic field. This work demonstrates new aspects of field-controllable ferrofluid droplets as a configurable and reprocessable metamaterial.

description: Genus Vertagopus Börner
In the conception of European Isotominae the genus is well defined with the presence of clavate tenent hairs on tibiotarsi, a full set of chaetae in apical tibiotarsal whorl (11), and two last abdominal segments separated. Two species of Buryatia show an incomplete set of the key characters mentioned above: V. asiaticus sp. nov. lost two Tchaetae in apical whorl (deficient set) while V. l a r i c i s has two last abdominal segments fused. Thus, Asiatic species make the status of the genus more questionable although the value of differentiating characters of Vertagopus were already doubted long before (Fjellberg 1978).
The local species of the species can be classified by the ecology into two groups: xylophilic species related with rotten wood (asiaticus sp. nov., pseudocinereus) and xerophilic species inhabiting dry litter, mosses and lichens (ceratus sp. nov., laricis, westerlundi).

The Scale of New Physics from the Higgs Couplings to $γγ$ and $γZ$

description: Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing processes that violate tree-level unitarity at some energy scale, indicating new physics. In this paper, we extend previous work on unitarity bounds from the Higgs potential and the Higgs couplings to vector bosons and the top quark; to the Higgs couplings to $γγ$ and $γZ$. We find that while the HL-LHC might be able to find new physics in the $γZ$ sector, the scale of new physics in both sectors is mostly beyond its reach. However, accurate measurements of the leading couplings of the two sectors in the HL-LHC can place stringent limits on both the scale of new physics and on other Higgs couplings that are difficult to measure. In addition, the scale of new physics is mostly within the reach of the $100$ TeV collider.

Aspects of entanglement in non-local field theories with fractional Laplacian

description: In recent years, various aspects of theoretical models with long range interactions have attracted attention, ranging from out-of-time-ordered correlators to entanglement. In the present paper, entanglement properties of a simple non-local model with long-range interactions in the form of a fractional Laplacian is investigated in both static and a quantum quench scenario. Logarithmic negativity, which is a measure for entanglement in mixed states is calculated numerically. In the static case, it is shown that the presence of long-range interaction ensures that logarithmic negativity decays much slower with distance compared to short-range models. For a sudden quantum quench, the temporal evolution of the logarithmic negativity reveals that, in contrast to short-range models, logarithmic negativity exhibits no revivals for long-range interactions for the time intervals considered. To further support this result, a simpler measure of entanglement, namely the entanglement entropy is also studied for this class of models.

Patient perspectives and reactions to unanticipated positive test results via population genomic screening efforts: a qualitative study
Creators: name: Vailionis, Eva Maria
Publisher: name: No Publisher Supplied
Year: 2022

description: The use of genomic screening initiatives to assess risk for genetic disease in the general population is increasing. However, little is known about the psychological reactions of patients who receive clinically-significant genetic testing results when their personal and family histories do not align with their molecular diagnosis. This qualitative study aims to analyze the reactions of participants who tested positive for pathogenic/likely pathogenic genetic variants in two conditions through Geisinger’s MyCode Genomic Screening and Counseling (GSC) program. The individuals were screened for personal and family histories that appeared inconsistent with their genetic result to assess perspectives when these results are hypothetically unanticipated. Thirteen individuals were interviewed and took part in the study. Interviews were conducted via phone using a semi-structured interview guide, and transcripts were analyzed using grounded, structural coding for themes that emerged through Interpretative Phenomenological Analysis (IPA). Results indicate that, in general, unanticipated genetic results are not accompanied by persistent negative emotions in this cohort. Every participant reported at least some positive emotion, and all recognized the prospective benefits of population genomic screening in varying ways. There were some exceptions, however, and these perspectives may aid in bettering GSC programs so participants feel better prepared to consent to testing and receive results.

description: 3D topological solitons are marvels of mathematical physics that arise in theoretical models in elementary particle and nuclear physics, condensed matter, and cosmology. A particularly interesting type of them is described by the mathematical Hopf map from a hypersphere to an ordinary sphere, which in the physical 3D space exhibits inter-linked circle-like or knotted localized regions of constant order parameter values. Despite their prevalence in models, such solitons remained experimentally elusive until recently, when hopfions were discovered in colloids and chiral liquid crystals, whereas the so-called "heliknotons" were found both individually and within triclinic 3D lattices while smoothly embedded in a helical background of chiral liquid crystals. Constrained by mathematical theorems, stability of these 3D excitations is thought to rely on a delicate interplay of competing free energy contributions, requiring applied fields or confinement. Here we describe such 3D solitons in a material system where no applied fields or confinement are required. Nevertheless, electric fields allow for inter-transforming heliknotons and hopfions to each other, as well as for 3D hopping-like dynamics arising from nonreciprocal evolution of the molecular alignment field in response to electric pulses. Stability of these solitons both in and out of equilibrium can be enhanced by tuning anisotropy of parameters that describe energetic costs of gradient components in the field, which is implemented through varying chemical composition of liquid crystal mixtures. Numerical modelling reproduces fine details of both the equilibrium structure and Hof-index-preserving out-of-equilibrium evolution of the molecular alignment field during switching and motions. Our findings may enable myriads of solitonic condensed matter phases and active matter systems, as well as their technological applications.

description: We revisit the constraints on semileptonic operators derived from the mono-$τ$ high-$p_T$ events in $pp$ collisions at LHC. Like in previous studies, we obtain limits on the New Physics couplings from the CMS data much stronger than from the ATLAS data, despite a nearly equal integrated luminosity. We find that a neglected systematics on the $τ$ lepton reconstruction efficiency can partly explain that difference. We then provide new limits on the New Physics couplings relevant to decays based on $b\to cτ\barν$ by using the recent ATLAS data with 139 ${\rm fb}^{-1}$. We also show that the inclusion of propagation of the New Physics particle can significantly worsen the bounds obtained by relying on Effective Field Theoretical treatment of New Physics.

description: The stability of the electrical network in Denmark varies in correspondence with the usage of the consumer. At peek usage the stability is secured by backup networks which are more expensive. Normally the consumers have no awareness of this, even though the price of the electricity varies from times with low consumption to high consumption. A simple electrical unit could help monitoring this perspective automatically, and thereby prevent peak situations on the electrical network. This will protect the consumer from overpriced electricity by mainly exploiting the power while the price is relatively low.

description: This work presents an analysis of a hidden charmed pentaquark candidate state with double strange quark in its quark content. The investigation is performed in two parts, which provide the mass prediction of the considered state and its partial decay widths for the $P_{css}\rightarrow Ξ^0 J/ψ$ and $P_{css}\rightarrow Ξ_c^+ D_s^-$ channels. For the analyses, two-point and three-point QCD sum rule methods are applied to get the mass and the widths, respectively. The mass for this candidate state is obtained as $m_{P_{css}}=4600 \pm 155$ MeV with corresponding current coupling constant $λ_{P_{css}}=(0.81 \pm 0.21)\times 10^{-3}$ GeV$^6$. These results are used in the analysis of the partial widths of this state for the decays $P_{css}\rightarrow Ξ^0 J/ψ$ and $P_{css}\rightarrow Ξ_c^+ D_s^-$. From these decays, the total width is obtained as $Γ= 12.29\pm 2.94 $ MeV. These results may shed light on the future experimental searches in which such types of states are probed and may provide information to discriminate between such possible observations.

title: "Do schools matter?" A study of behaviour which is a cause for concern in primary and secondary schools

Subjects: subject: Educational psychology

description: This study is concerned with different types of pupil behaviour which are a cause concern in primary and secondary schools in Strathclyde Region. The frequency of each type of behaviour is established together with likely teacher response. Teacher opinion on the climate within their own school is also explored as is their opinion on general educational issues. The historical development of each of the main approaches to behaviour is discussed, together with the school systems associated with these and it is within this theoretical framework that the data is analysed. Information was gathered by questionnaire from a sample consisting of 5% of Strathclyde schools and the data analysed using the Statistical Package for the Social Sciences. The results of the study indicate that the type of behaviour which is most likely to cause concern to teachers is that which is described as being "manipulative" in nature. A detailed analysis of this type of pupil behaviour is carried out, and takes into consideration the teachers' age, gender and position within the school. The level of occurrence of such behaviour is established, and when viewed within the context of school size and social deprivation status, the teaching groups most likely to experience the behaviour are identified. This data was contrasted with teacher opinion on school ethos/climate and differing perspectives of male and female, promoted and unpromoted, and younger and older teachers were revealed. This study concludes with suggestions on school systems which could assist pupils and staff to develop an educational environment supportive for all.

description: We describe a proposal to add a set of very forward detectors to the CMS experiment for the high-luminosity era of the Large Hadron Collider to search for beyond the standard model long-lived particles, such as dark photons, heavy neutral leptons, axion-like particles, and dark Higgs bosons. The proposed subsystem is called FACET for Forward-Aperture CMS ExTension, and will be sensitive to any particles that can penetrate at least 50 m of magnetized iron and decay in an 18 m long, 1 m diameter vacuum pipe. The decay products will be measured in detectors using identical technology to the planned CMS Phase-2 upgrade.

description: Natural products and their derivatives have historically been invaluable as a source of therapeutic agents and our natural environment remains a non-exhausted creative pool for the discovery and synthesis of new drug compounds. Natural products can be viewed as a population of privileged structures selected by evolutionary pressures to interact with a wide variety of proteins and other biological targets for specific purposes. On basis of these concepts, in the proposed project the natural compounds from plants used in ayurveda, the traditional Indian medicine will be mapped to the chemical space. Advanced bioinformatics tools will be used to propose potential new ligands of natural origin for the drug development.

Improving Wind Power Forecasts by considering the Spatio-Temporal structure of Wind Power Forecast Errors

description: With the ongoing increase in installed wind power production and due to the variability of this resource, forecasting the production is becoming a critical process. So far, forecasts have usually been generated individually for a given site of interest (either a wind farm or a group of wind farms). However, it is intuitively expected that owing to the inertia of meteorological forecasting systems, a forecast error made at a given point in space and time will be related to forecast errors at other points in space in the following period. The existence of such underlying correlation patterns is demonstrated and analyzed, considering a simple case-study of western Denmark. Wind direction is shown to play a crucial role, while the effect of wind speed is more complex. Models permitting capture of the interdependence structure of wind power forecast errors are proposed, and their efficiency discussed. Even though focus is on one-hour-ahead forecast errors and on western Denmark only, results show significant improvements and motivates a generalization to further look-ahead times, larger areas, or more complex topographies.

The Formation of Intermediate Mass Black Holes in Galactic Nuclei

description: Most stellar evolution models predict that black holes (BHs) should not exist above approximately $50-70$ M$_\odot$, the lower limit of the pair-instability mass gap. However, recent LIGO/Virgo detections indicate the existence of BHs with masses at and above this threshold. We suggest that massive BHs, including intermediate mass black holes (IMBHs), can form in galactic nuclei through collisions between stellar-mass black holes and the surrounding main-sequence stars. Considering dynamical processes such as collisions, mass segregation, and relaxation, we find that this channel can be quite efficient, forming IMBHs as massive as $10^4$ M$_\odot$. This upper limit assumes that (1) the BHs accrete a substantial fraction of the stellar mass captured during each collision and (2) that the rate at which new stars are introduced into the region near the SMBH is high enough to offset depletion by stellar disruptions and star-star collisions. We discuss deviations from these key assumptions in the text. Our results suggest that BHs in the pair-instability mass gap and IMBHs may be ubiquitous in galactic centers. This formation channel has implications for observations. Collisions between stars and BHs can produce electromagnetic signatures, for example, from x-ray binaries and tidal disruption events. Additionally, formed through this channel, both black holes in the mass gap and IMBHs can merge with the supermassive black hole at the center of a galactic nucleus through gravitational waves. These gravitational wave events are extreme and intermediate mass ratio inspirals (EMRIs and IMRIs, respectively).

description: Photodetection is an indispensable function of optoelectronic devices in modern communication and sensing systems. Contrary to the near-infrared/visible regions, the fast and sensitive photodetectors operated at room temperature for the far-infrared/terahertz regions are not well developed despite a possibly vast range of applications. The bulk photovoltaic effect (BPVE) in single-phase noncentrosymmetric materials based on the shift current mechanism enables less-dissipative energy conversion endowed with instantaneous responsivity owing to the quantum-mechanical geometric phase of electronic states. Nevertheless, the small-band-gap material for the low-energy BPVE inevitably suffers from the thermal noise due to the intrinsically high conductivity. Here, we demonstrate the shift current induced by soft-phonon excitations without creation of electron-hole pairs in the archetypal ferroelectric BaTiO3 by using the terahertz light, whose energy scale is three orders of magnitude smaller than the electronic band gap. At and above room temperature, we observe appreciable photocurrents caused by the soft-phonon excitation as large as that for electronic excitation and their strong phonon-mode dependence. The observed phonon-driven BPVE can be well accounted for by the shift current model considering the electron-phonon coupling in the displacement-type ferroelectrics as supported by the first-principles calculation. Our findings establish the efficient quantum BPVE arising from low-energy elementary excitations, suggesting the novel principle for the high-performance terahertz photodetectors.
