description: Resistive Plate Chamber (RPC) is a well-known gaseous detector in the field of High Energy Physics (HEP) experiments for its good tracking capability, high efficiency, good time resolution, and low cost of fabrication. The main issue in RPC is its limitation in the rate handling capability. Several experimental groups have developed sophisticated techniques to increase the particle rate capability and reduce the noise rate of this detector. In this article, we discussed a new method for linseed oil coating in case of bakelite RPC detector to achieve good efficiency and the results obtained using a conventional gas mixture.
50 TeV HEGRA Sources and Infrared Radiation

description: The recent observations of 50 TeV gamma radiation by HEGRA have the potential of determining the extragalactic flux of infrared radiation. The fact that radiation is observed in the range between 30 and 100 TeV sets an upper limit on the infrared flux, while a cutoff at $E_γ \approx 50$ TeV fixes this flux with a good accuracy. If the intrinsic radiation is produced due to interaction of high energy protons with gas or low-energy target photons, then an accompaning high-energy neutrino flux is unavoidable. We calculate this flux and underground muon flux produced by it. The muon flux is dominated by muons with energies about 1 TeV and can be marginally detected by a 1 km$^2$ detector like an expanded AMANDA.

description: The liquid-phase exfoliation (LPE) of black phosphorus (BP) is a strategic route for the large-scale production of phosphorene and few-layer BP (FL-BP) flakes. The exploitation of this exfoliated material in cutting-edge technologies, e.g., in flexible electronics and energy storage, is however limited by the fact that the LPE of BP is usually carried out at a high boiling point and in toxic solvents. In fact, the solvent residual is detrimental to device performance in real applications; thus, complete solvent removal is critical. Here, we tackle these issues by exfoliating BP in different low boiling-point solvents. Among these solvents, we find that acetone also provides a high concentration of exfoliated BP, leading to the production of FL-BP flakes with an average lateral size and thickness of c.a. 30 and 7 nm, respectively. The use of acetone to produce less defective few-layer BP flakes (FL-BPacetone) from bulk crystals is a straightforward process which enables the rapid preparation of homogeneous thin films thanks to the fast solvent evaporation. The ratio of edge to bulk atoms for the BP flakes here produced, combined with the use of low-boiling-point solvents for the exfoliation process suggests that these thin films are promising anodes for lithium-ion batteries. To this end, we tested Li-ion half cells with FL-BPacetone anodes achieving a reversible specific capacity of 480 mAh/g at a current density of 100 mA/g, over 100 charge/discharge cycles. Moreover, a reversible specific capacity of 345 mAh/g is achieved for the FL-BPacetone-based anode at a high current density (i.e., 1 A/g). These findings indicate that the FL-BPacetone-based battery is promising with regards to the design of fast charge/discharge devices. Overall, the presented process is a step forward toward the fabrication of phosphorene-based devices.

description: The spherically symmetric potential $a \,δ(r-r_0)+b\,δ' (r-r_0)$ is generalised for the $d$-dimensional space as a characterisation of a unique selfadjoint extension of the free Hamiltonian. For this extension of the Dirac delta, the spectrum of negative, zero and positive energy states is studied in $d\geq 2$, providing numerical results for the expectation value of the radius as a function of the free parameters of the potential. Remarkably, only if $d=2$ the $δ$-$δ'$ potential for arbitrary $a>0$ admits a bound state with zero angular momentum.

description: For a positive integer r, an r-spin topological quantum field theory is a 2-dimensional TQFT with tangential structure given by the r-fold cover of SO_2 . In particular, such a TQFT assigns a scalar invariant to every closed r-spin surface Sigma. Given a sequence of scalars indexed by the set of diffeomorphism classes of all such Sigma, we construct a symmetric monoidal category C and a C-valued r-spin TQFT which reproduces the given sequence. We also determine when such a sequence arises from a TQFT valued in an abelian category with finite-dimensional Hom spaces. In particular, we construct TQFTs with values in super vector spaces that can distinguish all diffeomorphism classes of r-spin surfaces, and we show that the associated algebras are necessarily non-semisimple.

We show the existence of codes with these parameters as well as their weight distributions by constructing an infinite family of two-weight codes. Previously known codes constructed by Shi et al. (\emph{Des Codes Cryptogr.} {\bf 88}(3):1-13, 2020) can be derived as a special case of our results. We also prove that the Gray image of any Plotkin-optimal two-Lee weight projective codes over $\mathbb{Z}_4$ has the same parameters and weight distribution as some two-weight binary projective codes of type SU1 in the sense of Calderbank and Kantor (\emph{Bull. Lond. Math. Soc.} {\bf 18}:97-122, 1986).

It was found from magnetic measurements that Ba$_2$La$_2$CoTe$_2$O$_{12}$ can be described as a spin-1\2 triangular-lattice antiferromagnet with easy-plane anisotropy at low temperatures. This compound undergoes a magnetic phase transition at $T_{\rm N}\,{=}\,3.26$ K to an ordered state with the $120^{\circ}$ structure. The magnetization curve exhibits the one-third plateau characteristic of triangular-lattice quantum antiferromagnets. The antiferromagnetic exchange interaction and the $g$ factors parallel and perpendicular to the $c$ axis were evaluated to be $J/k_{\rm B}\,{=}\,22$ K, $g_{\parallel}\,{=}\,3.5$ and $g_{\perp}\,{=}\,4.5$, respectively.

Locating disparities in machine learning

description: Machine learning can provide predictions with disparate outcomes, in which subgroups of the population (e.g., defined by age, gender, or other sensitive attributes) are systematically disadvantaged. In order to comply with upcoming legislation, practitioners need to locate such disparate outcomes. However, previous literature typically detects disparities through statistical procedures for when the sensitive attribute is specified a priori. This limits applicability in real-world settings where datasets are high dimensional and, on top of that, sensitive attributes may be unknown. As a remedy, we propose a data-driven framework called Automatic Location of Disparities (ALD) which aims at locating disparities in machine learning. ALD meets several demands from industry: ALD (1) is applicable to arbitrary machine learning classifiers; (2) operates on different definitions of disparities (e.g., statistical parity or equalized odds); and (3) deals with both categorical and continuous predictors even if disparities arise from complex and multi-way interactions known as intersectionality (e. g., age above 60 and female). ALD produces interpretable audit reports as output. We demonstrate the effectiveness of ALD based on both synthetic and real-world datasets. As a result, we empower practitioners to effectively locate and mitigate disparities in machine learning algorithms, conduct algorithmic audits, and protect individuals from discrimination.

description: In the coming years gravitational-wave detectors will undergo a series of improvements, with an increase in their detection rate by about an order of magnitude. Routine detections of gravitational-wave signals promote novel astrophysical and fundamental theory studies, while simultaneously leading to an increase in the number of detections temporally overlapping with instrumentally- or environmentally-induced transients in the detectors (glitches), often of unknown origin. Indeed, this was the case for the very first detection by the LIGO and Virgo detectors of a gravitational-wave signal consistent with a binary neutron star coalescence, GW170817. A loud glitch in the LIGO-Livingston detector, about one second before the merger, hampered coincident detection (which was initially achieved solely with LIGO-Hanford data). Moreover, accurate source characterization depends on specific assumptions about the behavior of the detector noise that are rendered invalid by the presence of glitches. In this paper, we present the various techniques employed for the initial mitigation of the glitch to perform source characterization of GW170817 and study advantages and disadvantages of each mitigation method. We show that, despite the presence of instrumental noise transients louder than the one affecting GW170817, we are still able to produce unbiased measurements of the intrinsic parameters from simulated injections with properties similar to GW170817.

description: The electrical resistivity of the unconventional superconductor UTe$_2$ shows very anisotropic behavior in the normal state depending on the current direction. In the present paper we show that the maximum in the resistivity $ρ_c$ for current applied along the $c$ axis at $T^{\rm max}_{ρ_c} \approx 14.75$~K follows the minimum in the thermal expansion $T_α^\star$ along $b$ axis. Under a magnetic field applied along the $b$ axis, $T^{\rm max}_{ρ_c}$ can be tracked up to the critical point of the first order metamagnetic transition, which is located near 6~K and 34.5~T. Surprisingly, at the metamagnetic field $H_m$ the resistivity $ρ_c$ shows a steplike decrease while the resistivities $ρ_a$ and $ρ_b$, for current along the $a$ and $b$ axis, respectively, show a steplike increase. Under hydrostatic pressure $T^{\rm max}_{ρ_c}$ and $H_m$ decrease significantly up to the critical pressure $p_c$ at which superconductivity is suppressed and a long range antiferromagnetic order appears. We show that the phase diagram at different pressures can be scaled by $T^{\rm max}_{ρ_c}$ in field and temperature suggesting that this temperature scale is governing the main interactions in the normal state.

description: During the last 10 years the environmental conditions in the New Forest (Hampshire, UK) has changed dramatically: the natural ecosystem structure of this unique natural reserve has been affected by the invasion of the bracken (Pteridium aquilinum) – the noxious weed that has spread rapidly over the area of 10*10 km in the New Forest. This paper focuses on remote sensing techniques advantages for environmental monitoring and investigating the endangered area using ENVI software and Landsat Imagery. Using satellite imagery classification will highlight the exact area where the spread of bracken has taken place, its change during the years, and the speed of bracken's spreading (change of bracken coverage in percents), thus helping in environmental decisions making and protecting the unique ecosystem of the National Park of the New Forest.

description: By projecting onto complex optical mode profiles, it is possible to estimate arbitrarily small separations between objects with quantum-limited precision, free of uncertainty arising from overlapping intensity profiles. Here we extend these techniques to the time-frequency domain using mode-selective sum-frequency generation with shaped ultrafast pulses. We experimentally resolve temporal and spectral separations between incoherent mixtures of single-photon level signals ten times smaller than their optical bandwidths with a ten-fold improvement in precision over the intensity-only Cramér-Rao bound.

description: We study the expected spin misalignments of merging binary black holes (BHs) formed in isolation by combining state-of-the-art population-synthesis models with efficient post-Newtonian evolutions, thus tracking sources from stellar formation to gravitational-wave detection. We present extensive predictions of the properties of sources detectable by both current and future interferometers. We account for the fact that detectors are more sensitive to spinning BH binaries with suitable spin orientations and find that this significantly impacts the population of sources detectable by LIGO, while this is not the case for 3rd-generation detectors. We find that three formation pathways, differentiated by the order of core collapse and common-envelope phases, dominate the observed population, and that their relative importance critically depends on the recoils imparted to BHs at birth. Our models suggest that measurements of the "effective-spin" parameter $χ_{\rm eff}$ will allow for powerful constraints. For instance, we find that the role of spin magnitudes and spin directions in $χ_{\rm eff}$ can be largely disentangled, and that the symmetry of the effective-spin distribution is a robust indicator of the binary's formation history. Our predictions for individual spin directions and their precessional morphologies confirm and extend early toy models, while exploring substantially more realistic and broader sets of initial conditions. Our main conclusion is that specific subpopulations of BH binaries will exhibit distinctive precessional dynamics: these classes include (but are not limited to) sources where stellar tidal interactions act on sufficiently short timescales, and massive binaries produced in pulsational pair-instability supernovae. Measurements of BH spin orientations have enormous potential to constrain specific evolutionary processes in the lives of massive binary stars.

description: Radial pulsations of newborn neutron stars (protoneutron stars) are studied for a range of internal temperatures and entropies per baryon predicted by the existing numerical simulations. Protoneutron star models are constructed using a realistic equation of state of hot dense matter, and under various assumptions concerning stellar interior (large trapped lepton number, zero trapped lepton number, isentropic, isothermal). Under prevailing conditions, linear oscillations of a protoneutron star can be treated as adiabatic, and evolutionary effects can be neglected on dynamic timescale. The dynamic behavior is governed by the adiabatic index, which in turn depends on the physical state of the stellar interior. The eigenfrequencies of the lowest radial modes of linear, adiabatic pulsations are calculated. Stability of protoneutron stars with respect to small radial perturbations is studied, and the validity of the static stability criteria is discussed.

description: Despite the recent findings on the inequality-increasing effect of homogeneous marriages, the growing body of literature on ‘the super-rich’, has missed out on illuminating contemporary global wealth inequality levels from a marital choice perspective. Not much is known about family formation at the top of the wealth distribution. By combining Forbes billionaires rich list data and billionaires’ Wikipedia articles with qualitative data, the paper presents a unique dataset capturing all US American billionaires (n = 948) and their spouses. The results suggest deeply ingrained traditional role allocations in billionaire couples. Female billionaires appear to be more likely to have a partner in the same upper-class fraction than male billionaires, who appear to be more liberal regarding their spouses’ class positions. By shedding light on the unique marriage demographics of the super-rich, the paper supports the importance of dynasty-making family strategies and social closure for understanding the economic elites of our times.

The reason is that one needs a large mass to avoid the tunneling via the Hawking Moss solution and a small mass for successful slow-rolling. However, Rubakov and Sibiryakov suggest that the Hawking Moss solution is not a solution for the false vacuum decay process because it does not satisfy the boundary condition. Hence, we have reconsidered the arguments for the defect of the simple polynomial model. We point out the possibility that one of the valley bounce belonging to a valley line in the functional space represents the decay process instead of the Hawking Moss solution. Under this presumption, we show an open inflation model can be constructed within the polynomial form of the potential so that the fluctuations can be reconciled with the observations.

description: Ecological processes maintaining landscape genetic variation and metacommunity structure in natural landscapes have traditionally been studied in isolation. Their integrated study may inform on whether major ecological processes affect species or landscapes differently, yielding a more cohesive understanding of the spatial organization of biodiversity. Here, we investigated the relative importance of spatial and environmental drivers on cladoceran metacommunity structure and the landscape genetic structure of its most widespread member, Daphnia magna, in soda pans of the Seewinkel region in Austria, covering the entire habitat network. These temporary pans exhibit strong environmental gradients, with wind serving as a key dispersal agent among them. Our study shows both parallels and divergences in the relative impacts of environmental sorting and spatial connectivity on landscape genetic versus metacommunity structure. The metacommunity primarily reflects environmental structuring, while spatial signals dominate in the D. magna metapopulation. The weaker environmental signal in Daphnia suggests that environmental gradients are not a key driver of landscape genetic structure in neutral markers. Prevailing wind direction was an important driver both in metacommunity and landscape genetic structure. This suggests its pivotal role across the two levels of ecological organization via determining connectivity among pans, thereby affecting dispersal and colonization rates, influencing both local species and genetic composition.

description: In this article, we report a simple, effective, sensitive, non-toxic and environmentally friendly method for the detection of dopamine (DA). This method utilises the property of the self-polymerization of dopamine under alkaline conditions, and gets the concentration of dopamine by measuring the fluorescence intensity of polydopamine (PDA) nanoparticles. And this method only uses NaHCO3 to start the polymerization process, so that the detection experiment becomes simple and inexpensive. The fluorescence intensities of the mixed solution produced at different reaction times and different concentrations were studied. Finally, a good linear relationship was obtained in the range of 1.0-400 μM with a correlation coefficient of 0.9946 and a detection limit of 0.3 μM. The method has high selectivity and important application value for detecting dopamine-related diseases.

description: We report on the high-efficiency storage and retrieval of weak coherent optical pulses and photonic qubits in a cavity-enhanced solid-state quantum memory. By using an atomic frequency comb (AFC) memory in a $Pr^{3+}:Y_2 SO_5$ crystal embedded in a low-finesse impedance-matched cavity, we stored weak coherent pulses at the single photon level with up to 62% efficiency for a pre-determined storage time of 2 $μ$s. We also confirmed that the impedance-matched cavity enhances the efficiency for longer storage times up to 70 $μ$s. Taking advantage of the temporal multimodality of the AFC scheme, we then store weak coherent time-bin qubits with (51+-2)% efficiency and a measurement-device limited fidelity over (94.8+-1.4)% for the retrieved qubits. These results represent the most efficient storage in a single photon level AFC memory and the most efficient qubit storage in a solid-state quantum memory up-to-date.

description: Inversion symmetric materials are forbidden to show an overall spin texture in their band structure in the presence of time-reversal symmetry. However, in van der Waals materials which lack inversion symmetry within a single layer, it has been proposed that a layer-dependent spin texture can arise leading to a coupled spin-layer degree of freedom. Here we use time-resolved Kerr rotation in inversion symmetric WSe$_{2}$ and MoSe$_{2}$ bulk crystals to study this spin-layer polarization and unveil its dynamics. Our measurements show that the spin-layer relaxation time in WSe$_2$ is limited by phonon-scattering at high temperatures and that the inter-layer hopping can be tunned by a small in-plane magnetic field at low temperatures, enhancing the relaxation rates. We find a significantly lower lifetime for MoSe$_{2}$ which agrees with theoretical expectations of a spin-layer polarization stabilized by the larger spin-orbit coupling in WSe$_2$.

description: We provide a framework for studying concrete C*-algebras associated with algebraic actions of semigroups: Given such an action, we construct an inverse semigroup, and we introduce conditions for algebraic actions that characterize Hausdorffness, topological freeness, and minimality of the associated tight groupoid. We parameterize all closed invariant subspaces of the unit space of our groupoid, and characterize topological freeness of the associated reduction groupoids. We prove that our groupoids are purely infinite whenever they are minimal, and in the topologically free case, we prove that our concrete C*-algebra is always a (possibly exotic) groupoid C*-algebra in the sense that it sits between the full and essential C*-algebras of our groupoid. As an application, we obtain structural results for C*-algebras associated with, for instance, shifts over semigroups, actions coming from commutative algebra, and non-commutative rings.

description: The Standard Model predicts that the electroweak couplings to the three charged leptons are identical. However, in the last decade, experimental measurements have suggested that semileptonic processes involving taus could have a slightly enhanced decay rate compared to their muonic counterparts. If confirmed, this would be an unambiguous sign of New Physics, with various scenarios introducing additional interactions that couple preferentially to the third generation. Two recent lepton universality tests performed at LHCb are presented in this proceedings of the first edition of the New Frontiers in Lepton Flavour workshop.

description: Adaptive management is a union of science and management, because theoretical ideas about how better to manage natural resources are tested and proved experimentally, in according to the given real conditions of the ecosystem until we reach optimal decision with minimized impact upon the ecosystems. Actually, the role of the adaptive management in Environmental Decision Making become more and more important, as it deals with such a challenging problem as harmonious co-existence of the human and the earth: how best to manage natural resources, how to apply taken decisions upon ecosystems with minimal negative effect, how to maintain conservation of ecosystems with technological progress, thus providing effective dialogue ―man-nature‖. Adaptive management offers important insights into the sustainable governance of natural resources, because the awareness of the importance of good-quality environment requires decision-making management process adaptive to the environmental situation in exact condition and places on the Earth. Therefore, we conclude that adaptive management will play in the nearest future a key and a paramount role in the environmental decision-making for the sustainable development of our world.

description: A potential advantage of quantum machine learning stems from the ability of encoding classical data into high dimensional complex Hilbert space using quantum circuits. Recent studies exhibit that not all encoding methods are the same when representing classical data since certain parameterized circuit structures are more expressive than the others. In this study, we show the difference in encoding techniques can be visualized by investigating the topology of the data embedded in complex Hilbert space. The technique for visualization is a hybrid quantum based topological analysis which uses simple diagonalization of the boundary operators to compute the persistent Betti numbers and the persistent homology graph. To augment the computation of Betti numbers within a NISQ framework, we suggest a simple hybrid algorithm. Through a illuminating example of a synthetic data set and the methods of angle encoding, amplitude encoding, and IQP encoding, we reveal topological differences with the encoding methods, as well as the original data. Consequently, our results suggest the encoding method needs to be considered carefully within different quantum machine learning models since it can strongly affect downstream analysis like clustering or classification.

Hyperbilirubinemia

description: Hereditary spherocytosis (HS) is an inherited disorder characterized by intrinsic defects in the red cell membrane proteins. The molecular abnormality is heterogeneous and may affect several membrane proteins including spectrin, ankyrin, band 3 and protein 4.2. Most patients have icterus and cholestasis due to chronic hemolysis. Gilbert’s syndrome (GS) is a metabolic disorder characterized by a mild and chronic unconjugated hyperbilirubinemia in the absence of liver and hematologic disease. A polymorphism in the promoter of UGT1A1 gene has been shown to associate GS with a decrease of enzymatic activity to about 30%. The co-inheritance of HS and GS can exacerbate hyperbilirubinemia, and, therefore, it could be a confounding factor to define HS severity. The aim of our study was to evaluate the prevalence of GS in HS patients. We evaluated the bilirubin plasmatic level and the TA duplication in the repetitive TATA box sequence of the UGT1A1 gene promoter in 27 HS patients and 60 healthy individuals.
