description: We elaborate in this paper a translation-invariant model for fermions in 4-dimensional noncommutative Euclidean space. The construction is done on the basis of the renormalizable noncommutative translation-invariant Phi4 theory introduced by R. Gurau et al. We combine our model with the scalar model, in order to study the noncommutative pseudo-scalar Yukawa theory. After we derive the Feynman rules of the theory, we perform an explicit calculation of the quantum corrections at one loop level to the propagators and vertices.

description: Recent T2K data indicates a CP violation in the neutrino oscillations and mildly favours the normal neutrino mass hierarchy. This work explores the physics potentials with a combined sensitivity of T2K-II, NO$\nu$A, and JUNO experiments. T2K-II, a proposed run extension up to 2026 by T2K collaboration, is sensitive to CP violation at a level of $3\sigma$ or higher if $\delta_{CP}\sim-\pi/2$. NO$\nu$A is sensitive to both mass hierarchies and CP violation. JUNO, expected to take data from 2021, has $3\sigma$ or higher sensitivity to the mass hierarchy and 1% or better precision measurement of solar parameters and atmospheric mass splitting. A combined sensitivity of the three experiments allows us to achieve the most sensitivity to the CP violation and mass hierarchy before 2027 when Hyper-Kamiokande and DUNE are expected to start.

description: Based on masers with measured trigonometric parallaxes, we have redetermined the spatial orientation parameters of the Local (Orion) arm. Using 23 sources (the Gould Belt objects were excluded), we have found that their spatial distribution can be approximated by a very narrow ellipsoid elongated in the direction L_1=77.1+/-2.9^o whose symmetry plane is inclined to the Galactic plane at an angle of 5.6+/-0.2^o. The longitude of the ascending node of the symmetry plane is l_Ω=70+/-3^o. A new estimate for the pitch angle of the Local spiral arm has been obtained by an independent method: i=12.9+/-2.9^o. Previously, a belt of young B stars, the de Vaucouleurs.Dolidze belt, was pointed out on the celestial sphere with parameters close to such an orientation. We have refined the spatial orientation parameters of this belt based on a homogeneous sample of protostars. The de Vaucouleurs.Dolidze belt can be identified with the Local arm, with the belt proper as a continuous band on the celestial sphere like the Gould Belt being absent due to the peculiarities of the spatial orientation of the Local arm. Using the entire sample of 119 Galactic masers, we have shown that the third axis of their position ellipsoid has no deviation from the direction to the Galactic pole: B_3=89.7+/-0.1^o.

description: The non-modal linear stability of miscible viscous fingering in a two dimensional homogeneous porous medium has been investigated. The linearized perturbed equations for Darcy's law coupled with a convection-diffusion equation is discretized using finite difference method. The resultant initial value problem is solved by fourth order Runge-Kutta method, followed by a singular value decomposition of the propagator matrix. Particular attention is given to the transient behavior rather than the long-time behavior of eigenmodes predicted by the traditional modal analysis. The transient behaviors of the response to external excitations and the response to initial conditions are studied by examining the $ε-$pseudospectra structures and the largest energy growth function. With the help of non-modal stability analysis we demonstrate that at early times the displacement flow is dominated by diffusion and the perturbations decay. At later times, when convection dominates diffusion, perturbations grow. Furthermore, we show that the dominant perturbation that experiences the maximum amplification within the linear regime lead to the transient growth. These two important features were previously unattainable in the existing linear stability methods for miscible viscous fingering. To explore the relevance of the optimal perturbation obtained from non-modal analysis, we performed direct numerical simulations using a highly accurate pseudo-spectral method. Further, a comparison of the present stability analysis with existing modal and initial value approach is also presented. It is shown that the non-modal stability results are in better agreement, than the other existing stability analyses, with those obtained from direct numerical simulations.

description: In this paper, we report the results of measurements of the intensities and delays of super-radiance decays from excited helium atoms at multiple wavelengths. The experiment was performed using extreme ultraviolet radiation produced by the free electron laser at the SPring-8 Compact SASE Source test accelerator facility as an excitation source. We observed super-radiant transitions on the $1s3p \to 1s2s$ ($λ=$502 nm), $1s3d \to 1s2p$ ($λ=$668 nm), and $1s3s \to 1s2p$ ($λ=$728 nm) transitions. The pulse energy of each transition and its delay time were measured as a function of the target helium gas density. Several interesting features of the data, some of which appear to contradict with the predictions of the simple two-level super-radiance theory, are pointed out.
PROSPECT upgrade and science goals

description: The first phase of the Precision Reactor Oscillation and Spectrum (PROSPECT) experiment provided high-impact limits on sterile neutrino oscillations at the eV2 scale and a high-resolution measurement of the antineutrino spectrum due purely to 235U fission daughters. These goals remain well motivated by persistent discrepancies between measurement and prediction of both reactor flux and spectral shape. Leveraging this success, the PROSPECT collaboration is planning an upgraded detector that enables an expanded scientific program. An initial deployment at the High Flux Isotope Reactor will substantially enhance sensitivity to oscillation parameter space required for interpretation of long-baseline neutrino oscillation experiments and, through greatly improved statistical precision in the spectrum, provide complementary data constraining uncertainties in nuclear data for neutron rich fission daughters. A second, systematically-correlated deployment at a low-enriched-uranium reactor, would significantly improve the scientific reach of both measurements. We discuss this extended PROSPECT physics program.
Search for Invisible Modes of Nucleon Decay with the SNO+ Extended Water Data
Creators: name: Askins, Morgan
Publisher: name: Zenodo
Year: 2020

description: Many Grand Unified Theories predict processes that would allow baryons to decay to leptons, violating baryon number conservation and subsequently allowing for both protons and neutrons to decay through non-Standard Model interactions. Distinct from the high energy decay modes that very large water Cherenkov detectors are designed to look for are so-called invisible decays which are only detectable through their subsequent nuclear deexcitations. The SNO+ experiment is uniquely sensitive to this mode of decay due to its low energy threshold, low background radiation, and detector depth. Presented here are updated results using a second dataset which triples the total livetime with nearly 200 days of very low background.

description: The nEXO experiment is a proposed next-generation search for neutrinoless double beta decay ($0\nu\beta\beta$) of $^{136}$Xe based on a 5-tonne monolithic liquid xenon TPC. A detailed study of the expected sensitivity, published in 2016, calculated the 90% CL exclusion sensitivity on the $0\nu\beta\beta$ half-life to be $9.2\times10^{27}$ yrs. In this poster, we will present an updated sensitivity work based on advancements in the design and simulation of nEXO. Specific improvements include detailed, data-driven modeling of signal development in the charge readout tiles, the application of machine-learning analyses to improve signal/background separation, a more realistic accounting of the energy reconstruction including effects from scintillation light in the "skin" regions, new radioassay results of nEXO's components, and an updated detector geometry which reflects changes made to the engineering design over the past three years.

description: As melhorias na saúde ao longo do tempo têm sido alcançadas mediante um vasto leque de intervenções. Algumas diretamente ligadas ao contexto dos serviços de saúde (programas de vacinação) e outras mediante melhoria das condições de vida e do ambiente. Historicamente, a melhoria substantiva de diversos indicadores de saúde deve-se mais a medidas não médicas relacionadas com as condições de vida, saneamento básico, ambiente, qualidade do ar, condições dos locais de trabalho e de habitação do que a medidas médicas. No entanto, falar de saúde significa, na maioria das vezes, falar de medicina ou de cuidados de saúde e numa altura em que tantas pessoas não têm, ainda, acesso a cuidados de saúde para as suas manifestas necessidades, aumentam as visitas aos médicos de família para procedimentos preventivos, avaliações globais ou parciais de saúde. Os nossos serviços de saúde têm sofrido consideráveis mudanças nos últimos 30 anos e esta é uma delas. A medicina, dita preventiva, ocupa cada vez mais recursos nos Cuidados de Saúde Primários (CSP) e de uma prática dirigida a pessoas e famílias movemo-nos progressivamente para uma medicina centrada em populações. Sendo que esta deslocação da medicina curativa para a medicina preventiva é estimulada pela política de saúde, existindo mesmo incentivos financeiros neste sentido.

description: The PROSPECT experiment uses a multi-ton liquid scintillator detectors to make a precision measurement of the $^{235}$U spectrum from a research reactor. Other experiments, like Daya Bay and STEREO, make similar measurements using complementary strategies and designs. A combined analysis of the PROSPECT data with other measurements will improve over the sensitivity of the individual measurements, in particular with regards to the precision and sensitivity to spectral features. This poster presents an analysis framework for evaluating the compatibility between the individual data sets and combining the measurements of multiple, independent experiments. By unfolding the measurements from the detected energy of events into true energy space, a measurement of the underlying $^{235}$U reactor antineutrino spectrum can be made. Sensitivity to spectral distortions from neutrino oscillations and non-standard physics is also explored.
New Approach of explaining the missing sources of UHE Neutrinos as an Effect of Approaching Planck Length
Creators: name: Shehada, Abdullah
Publisher: name: Zenodo
Year: 2020

description: A new effect has been taken into account which has ever been used before in physics, this effect related to two different fields, Quantum physics, and General Relativity. This effect takes name: Time Dilatation as an Effect of Approaching Planck Length, this effect is completely different from the gravitational time dilatation in general relativity and time dilatation due to closing to the speed of light in special relativity. The new effect becomes obvious and strong for the particles that have high energies and very small diameters. Experiments in particle physics and astrophysics had got the conclusion that the particles may travel faster than the speed of light in vacuum, such as MINOS experiment and Fermilab1979 in particle experiments and supernova SN1987A and Gamma-Ray Bursts (GRBs) in astronomy eld. And that seems to violate the theory of relativity, but this theory can explain all these unusual observations easily.

description: Health and usage monitoring systems (HUMS) are the basis for condition-based maintenance of helicopters. One of the most critical systems in terms of safety and maintenance expense that can be monitored by HUMS are the main gearboxes of helicopters with turbine engines. While the health monitoring part of HUMS aims to model the health state from the collected sensor data with advanced algorithms, such as machine learning, the usage monitoring part tracks the time of use and operating parameters of the system, such as load, to determine lifetime consumption. In the presented work, a combination of automatic dependent surveillance-broadcast (ADS-B) flight data with a generic helicopter performance model is used to acquire torque profiles of the gearboxes. With damage accumulation methods, the load spectra are transformed to aggregated indicators that reflect the individual gearbox usage. The methodology is applied to samples of two helicopters from a five-year ADS-B data set of German helicopter emergency medical services (HEMS) acquired for the study. The results demonstrate the feasibility of the generic approach, which can support maintenance scheduling and new usage-based maintenance services independent of direct access to installed HUMS.

description: The Lao People's Democratic Republic (PDR) has the ambition to become the "battery of Asia" through exporting its hydro- and coal-powered electricity to neighbouring countries. However, increasing electricity exports needs to incorporate low-carbon electricity generation and transport infrastructure, if Lao is to meets its ambition while satisfying its local demand and climate targets. This briefing examines Lao's electricity generation projections and policies, and examines the material requirements for building projected systems. Challenges for future electricity requirements are described, alongside proposed governance actions to support low-carbon development. Building the required low-carbon electricity and transport systems involves renewable energy capacity additions, using low-carbon construction materials and securing their supply. Industrial capacity needs to be prepared and strategically planned to supply more electricity and transport system components domestically. Resource acquisition can be a challenge since Lao is landlocked, making it dependant on trade with its neighbours. Thus, revising supply chains and local governance is required.

description: In this paper, using properties of Ramanujan sums and of the discrete Fourier transform of arithmetic functions, we give an explicit formula for the number of solutions of the linear congruence $a_1x_1+\cdots +a_kx_k\equiv b \pmod{n}$, with $\gcd(x_i,n)=t_i$ ($1\leq i\leq k$), where $a_1,t_1,\ldots,a_k,t_k, b,n$ ($n\geq 1$) are arbitrary integers. As a consequence, we derive necessary and sufficient conditions under which the above restricted linear congruence has no solutions. The number of solutions of this kind of congruence was first considered by Rademacher in 1925 and Brauer in 1926, in the special case of $a_i=t_i=1$ $(1\leq i \leq k)$. Since then, this problem has been studied, in several other special cases, in many papers; in particular, Jacobson and Williams [{\it Duke Math. J.} {\bf 39} (1972), 521--527] gave a nice explicit formula for the number of such solutions when $(a_1,\ldots,a_k)=t_i=1$ $(1\leq i \leq k)$. The problem is very well-motivated and has found intriguing applications in several areas of mathematics, computer science, and physics, and there is promise for more applications/implications in these or other directions.

We consider the effect of parent mesons velocity, as well as, the effect of finite detector size. Using the expected upper limits on the number of events for the LNV decay modes, $M_{1}^{-} \to\ell_1^{-}\ell_2^{-}\pi^{+}$~($M_{1}=B, B_c,D, D_{s}\,\text{and}\,K$), we analyze the sensitivity reach of the mixing angles $|V_{e N}|^{2}$, $|V_{\mu N}|^{2}$, $|V_{\tau N}|^{2}$, $|V_{e N}V_{\mu N}|$, $|V_{e N}V_{\tau N}|$ and $|V_{\mu N}V_{\tau N}|$ as a function of heavy neutrino mass $M_{N}$. We show that, inclusion of parent meson velocity can account to a large difference for active-sterile mixing compare to existing bounds, specially for $D$, $D_s$ meson decay at SHiP and $K$ meson decay at NA62.

description: The proposed ICAL detector at the INO facility offers an unparalleled window to probe various beyond the Standard Model (BSM) scenarios by observing atmospheric neutrinos and antineutrinos separately over a wide range of energies and baselines. We study several interesting BSM scenarios using 50 kt ICAL such as: a) Non-Standard Neutrino Interactions (NSIs), b) Flavor-dependent Long-Range Forces (LRFs), and c) Indirect Detection of Galactic Diffuse Dark Matter. We demonstrate how the unique features of ICAL like its charge identification capability, reconstruction of hadron energy (inelasticity), and excellent energy and zenith angle reconstruction of charged muon in multi-GeV energy range help to explore the parameter space of these BSM physics.
title: Target State Optimization: Drivability Improvement for Vehicles with Dual Clutch Transmissions
Creators: name: Schmiedt, Marius

Publisher: name: MDPI
Year: 2022

description: Vehicles with dual clutch transmissions (DCT) are well known for their comfortable drivability since gear shifts can be performed jerklessly. The ability of blending the torque during gear shifts from one clutch to the other, making the type of automated transmission a perfect alternative to torque converters, which also comes with a higher efficiency. Nevertheless, DCT also have some drawbacks. The actuation of two clutches requires an immense control effort, which is handled in the implementation of a wide range of software functions on the transmission control unit (TCU). These usually contain control parameters, which makes the behavior adaptable to different vehicle and engine platforms. The adaption of these parameters is called calibration, which is usually an iterative time-consuming process. The calibration of the embedded software solutions in control units is a widely known problem in the automotive industry. The calibration of any vehicle subsystem (e.g., engine, transmission, suspension, driver assistance systems for autonomous driving, etc.) requires costly test trips in different ambient conditions. To reduce the calibration effort and the accompanying use of professionals, several approaches to automize the calibration process are proposed. Due to the fact that a solution is desired which can optimize different calibration problems, a generic metaheuristic approach is aimed. Regardless, the scope of the current research is the optimization of the launch behavior for vehicles equipped with DCT since, particularly at low speeds, the transmission behavior must meet the intention of the driver (drivers tend to be more perceptive at low speeds). To clarify the characteristics of the launch, several test subject studies are performed. The influence factors, such as engine sound, maximal acceleration, acceleration build-up (mean jerk), and the reaction time, are taken into account. Their influence on the evaluation of launch with relation to the criteria of sportiness, comfort, and jerkiness, are examined based on the evaluation of the test subject studies. According to the results of the study, reference values for the optimization of the launch behavior are derived. The research contains a study of existing approaches for optimizing driving behavior with metaheuristics (e.g., genetic algorithms, reinforcement learning, etc.). Since the existing approaches have different drawbacks (in scope of the optimization problem) a new approach is proposed, which outperforms existing ones. The approach itself is a hybrid solution of reinforcement learning (RL) and supervised learning (SL) and is applied in a software in the loop environment, and in a test vehicle.

description: In bacteria such as $\textit{Escherichia coli}$, DNA is compacted into a nucleoid near the cell center, while ribosomes$-$molecular complexes that translate messenger RNAs (mRNAs) into proteins$-$are mainly localized at the poles. We study the impact of this spatial organization using a minimal reaction-diffusion model for the cellular transcriptional-translational machinery. Our model predicts that $\sim 90\%$ of mRNAs are segregated to the poles and reveals a "circulation" of ribosomes driven by the flux of mRNAs, from synthesis in the nucleoid to degradation at the poles. To address the existence of non-specific, transient interactions between ribosomes and mRNAs, we developed a novel method to efficiently incorporate such transient interactions into reaction-diffusion equations, which allowed us to quantify the biological implications of such non-specific interactions, e.g. for ribosome efficiency.

description: This work aimed to assess the influence of the use and weight of shoulder bag on female gait. A cross-sectional study was conducted from April to September 2018, with 258 women (18-59 years old) who used shoulder bags. A questionnaire was used, and body weight and bag weight were measured. Gait was assessed with and without a bag using a baropodometer. The percentage of bag weight-body weight ratio was associated with having children (OR=0.210, p=0.002) and doing physical activity (OR=2.122, p=0.049). As for the side used to carry the bag, right stride length increased when the bag was carried on the opposite site and decreased when carried on both sides (p<0.05). There was a reduction of the left surface area and left foot peak pressure, and an increase in the left step length in relation to the percentage of weight carried (p<0.05). Regardless of the side used to carry the bag and the weight of the bag, the changes perceived during gait while carrying shoulder bags were discrete. However, attention should be drawn to these changes, mainly due to the adaptive capacity of the body and the long-term effects of bag use.

description: We report on recent improvements to our non-perturbative calculation of the positronium spectrum. Our Hamiltonian is a two-body effective interaction which incorporates one-photon exchange terms, but neglects fermion self-energy effects. This effective Hamiltonian is diagonalized numerically in a harmonic oscillator basis at strong coupling ($α=0.3$) to obtain the mass eigenvalues. We find that the mass spectrum compares favorably to the Bohr spectrum of non-relativistic quantum mechanics evaluated at this unphysical coupling.

description: Solvation is essential for protein activities. To study internal solvation of protein, site-directed mutagenesis is applied. Intrinsic fluorescent probe, tryptophan, is inserted into desired position inside protein molecule for ultrafast spectroscopic study. Here we review this unique method for protein dynamics researches. We introduce the frontiers of protein solvation, site-directed mutagenesis, protein stability and characteristics, and the spectroscopic methods. Then we present time-resolved spectroscopic dynamics of solvation dynamics inside caves of active sites. The studies are carried out on a globular protein, staphylococcal nuclease. The solvation at internal sites of the caves indicate clear characteristics of local environment. These solvation behaviors correlated to the enzyme activity directly.
title: Role of bacterial lipopolysaccharides in the modulation of platelet and megakaryocyte function
Creators: name: Vallance, Thomas Michael
Publisher: name: University of Reading
Year: 2020

description: Cardiovascular disease is a group of inflammatory diseases that is responsible for the plurality of deaths in the world. In ischaemic diseases, aberrant platelet activation leads to thrombus formation and occlusion of key arteries. Furthermore, platelets are critically involved in sepsis, where thrombocytopaenia is correlated with worse patient outcomes. Therefore, immune receptors, such as Toll-like receptor 4 (TLR4), have been identified as potential targets for reducing platelet activation by decoupling immune functions from haemostasis. Multiple experimental techniques were used to determine the impact of ultrapure lipopolysaccharide (LPS) chemotypes on platelet and megakaryocyte function as LPS is a specific ligand for TLR4. To determine whether LPS modulates platelet activity, LPS and platelets were co-incubated under different conditions. We determined that ultrapure LPS derived from various species of Gram-negative bacteria cannot significantly modulate platelet activity, as measured by aggregation, fibrinogen binding, and P-selectin exposure, except under specific conditions. This is potentially due to activation dependent cell�surface expression of TLR4. Subsequently, to investigate whether LPS induces inflammatory signalling in megakaryocytes, a novel megakaryocyte reporter cell line, Meg-01R, was developed and used to determine that ultrapure LPS is not sufficient on its own to modulate megakaryocyte function. Characterisation of this cell line suggests that MyD88-dependent signalling pathways are active in Meg-01R cells but TLR4 is not present in sufficient quantities at the cell surface. As LL37 directly binds to LPS and is also a strong platelet agonist, we investigated the impact of LPS on LL37- induced platelet activation. Here, we discovered a TLR4-independent cell-independent formation of LL37-LPS micelles that prevents LL37-induced platelet activation. Based on these results, LPS and TLR4 are not sufficient, in vitro, to decouple the immune function of platelets from haemostasis or induce changes in megakaryocyte function however it may still play an important role in conjunction with other immune receptors.

This thesis aims to study the, often porous, boundaries between different strata of the gentry; definitions of gentry status that were often arbitrary and depended on context, local developments and shifts in attitude across time. Networks of family and friendship were essential facilitators to social, political and cultural success and relevance across the strata of lesser gentry. The study builds on existing work regarding the smaller gentry families variously described as the squirarchy, minor, lesser or parish gentry in the work of Vickery, French and Hague. Based on a review of the literature and historiographical debate, knowledge and evidence were collected by using a variety of multi-disciplinary sources to build a comprehensive picture to better understand the complex issues of social identity, behaviour and influence of lesser gentry families. The Wade family were unremarkable, making little impact on regional or national history. This inconspicuousness is precisely the point of investigating their origins, landholdings, allies, material culture, status, and wealth. They were representative of a group of gentry that was numerous, old fashioned, conservative and restrained. The term ‘lesser gentry’ covers a broad range of gentry families, diverse in size, wealth, social connection and geography. However, within their ranks, they shared a belief in a natural order embracing self-belief in their right to authority and an elevated social position.

description: Phantasms in the Halls: A Future University is Possible, is a mediated live performance presented synchronously on Zoom and in person. In this devised ensemble piece, the performers offer a performative response to recent scholarship on the settler colonial university and its significance in the time of the COVID-19 pandemic. The work weaves together theories of fugitivity, spectrality, and refusal to offer contextually situated critiques of labor practices under quarantine. The performance form works in collaboration with its critical content to offer an embodied, albeit mediated, look into what decolonizing academic labor can look like in a moment of global epistemic upheaval and collective survival.

Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Neutralino pair production via photon-photon collisions is analyzed in the context of Minimal Supersymmetric Standard Model at future linear collider. Since photon does not have self coupling, this process is only possible at Next-to-Leading order and all the possible terms are calculated for the photon-photon interaction, including box, triangles and quartic coupling diagrams. Numerical analysis of the production rates for $ \tildeχ^0_1 \tildeχ^0_1$, $ \tildeχ^0_1 \tildeχ^0_2$ and $ \tildeχ^0_2 \tildeχ^0_2$ are presented for four new distinct benchmark models which are presented in the light of LHC8. Angular dependence of each neutralino pairs for the benchmark points are also presented. Total integrated photonic cross section goes up to $1.23\;fb$ and $1.26\;fb$ for the $ \tildeχ^0_1 \tildeχ^0_1$ and $ \tildeχ^0_2 \tildeχ^0_2$ pairs, respectively for the Radiatively driven natural susy benchmark point.

description: Hepatic hydrothorax (HH) is associated with a poor prognosis. Liver transplant (LT) is the best treatment modality. We aim to assess post-LT morbidity and mortality in patients with cirrhosis and HH. Adult patients with cirrhosis, who underwent LT at our institution from 2015 to 2020, were retrospectively reviewed. Baseline data was obtained at the time of LT. Patients were followed from baseline until the last follow-up or death. Censoring occurred at the time of the last follow-up or death, whichever occurred earlier. Cumulative incidence of outcomes was determined by the Kaplan–Meier method. Short-term post-operative complications were compared between both groups as well. 428 patients had a LT, of which 72 (16.8%) had HH. Most of the baseline characteristics were similar between patients with and without HH; however, patients in the HH group had a higher proportion of pre-operative history of ascites and hepatic encephalopathy. Pre-operative HH was not significantly associated with post-LT mortality (Hazard ratio 1.12, 95% confidence interval 0.54-2.32; P-value 0.76). Patients had similar short-term post-operative complications between both groups. LT is an excellent therapeutic option for patients with cirrhosis and HH, with excellent long-term survival without increased morbidity.
From oscillation dip to oscillation valley in atmospheric neutrino experiments

description: Atmospheric neutrino experiments can show the "oscillation dip" feature in data, due to their sensitivity over a large $L/E$ range. In experiments that can distinguish between neutrinos and antineutrinos, like INO, oscillation dips can be observed in both these channels separately. We present a data-driven approach -- that uses the asymmetry in the up and down events, binned in the reconstructed $L/E$ of muons – to demonstrate the dip, thereby confirming the oscillation hypothesis. We further propose, for the first time, the identification of an "oscillation valley" in the ($E_{\mu} - \cos\theta_{\mu}$) plane, feasible for detectors like INO having excellent muon energy and direction resolutions. We illustrate how this two-dimensional valley offers a clear visual representation and test of the $L/E$ dependence, the alignment of the valley quantifying the atmospheric mass-squared difference.
$0\nu\beta\beta$ in left-right theories with Higgs doublets and gauge coupling unification

description: We consider a version of Left-Right Symmetric Model with Higgs bidoublet ($\Phi$) ($B-L=0$), Higgs doublets ($H_{L,R}$) ($B-L=1$) and a charged scalar ($\delta^+$) ($B-L=2$) leading to radiatively generated Majorana masses for neutrinos and thereby, leads to new physics contributions to $0\nu\beta\beta$. We have embedded the model in a non-SUSY $SO(10)$ GUT leading to successful gauge coupling unification. The model can also be extended to phenomenologically detect $W_R, Z_R$ bosons in LHC and future collider searches. In the context of neutrinoless double beta decay, this model can saturate the present bound from GERDA and KamLAND-Zen experiments. Also, we briefly explain how keV-MeV range RH neutrino arising from our model can saturate various astrophysical and cosmological constraints and can be considered as warm Dark Matter (DM) candidate to address various cosmological issues.

description: A 1D metallic surface state was created on an anisotropic InSb(001) surface covered with Bi. Angle-resolved photoelectron spectroscopy (ARPES) showed a 1D Fermi contour with almost no 2D distortion. Close to the Fermi level ($E_{\rm F}$), the angle-integrated photoelectron spectra showed power-law scaling with the binding energy and temperature. The ARPES plot above $E_{\rm F}$ obtained thanks to thermally broadened Fermi edge at room temperature showed a 1D state with continuous metallic dispersion across $E_{\rm F}$ and power-law intensity suppression around $E_{\rm F}$. These results strongly suggest a Tomonaga-Luttinger liquid on the Bi/InSb(001) surface.

Sensitivity of the LUX-ZEPLIN experiment to the 0νββ decay of Xe-136
Creators: name: Silva, Claudio Frederico Pascoal Da
Publisher: name: Zenodo
Year: 2020

description: The LUX-ZEPLIN (LZ) experiment is a 7-tonne liquid xenon time projection chamber primarily designed to search for dark matter particles in the form of weakly interacting massive particles. Nonetheless, we can take advantage of the significant ${}^{136}$Xe mass (>600 kg) present in the active volume of the detector to look for neutrinoless double beta decay of that isotope. We report the projected LZ sensitivity to this decay after 1000 live-days without isotopic enrichment (half-life>$1.06\times 10^{26}$ years, 90% CL) and with a 90% isotopic enrichment with ${}^{136}$Xe (half-life>$1.06×10^{27}$ years, 90% CL). This result makes use of a profile likelihood ratio (PLR) method and includes updated background models, namely from the cavern walls, from the solar neutrinos, and neutron capture on ${}^{136}$Xe.
Neutrino oscillations in a magnetic field and CP violation: The three-flavor case

name: Lichkunov, Alexey

Publisher: name: Zenodo
Year: 2020

description: We develop an approach to neutrino oscillations in a magnetic field and extend it to the case of three neutrino generations. The theoretical framework suitable for computation of the Dirac neutrino spin, flavour and spin-flavour oscillations probabilities in a magnetic field is given. The closed analytic expressions for the probabilities of oscillations are obtained accounting for the normal and inverted hierarchies and the possible effect of CP violation. In particular, it is shown that the probabilities of conversions without neutrino flavor change (νLe→νLe and νLe→νRe) do not exhibit the dependence on the CP phase, while other neutrino conversions are affected by the CP phase. In general, the neutrino oscillation probabilities exhibit quite a complicated interplay of oscillations on the magnetic μνB and vacuum frequencies. The obtained are of interest to neutrino oscillations in extreme astrophysical environments such as magnetars and supernovas, as well as neutrino propagation in interstellar magnetic fields.

description: Axitinib was approved for treatment of advanced renal cell carcinoma (RCC). The current study was to assess axitinib-related adverse events (AEs) through data mining of the US Food and Drug Administration Adverse Event Reporting System (FAERS). Disproportionality analyses, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS) algorithms, were employed to quantify the signals of axitinib-associated AEs. Out of 10,703,806 reports collected from the FAERS database, 9044 reports of axitinib as the ‘primary suspected (PS)’ AEs were identified. Axitinib induced AEs occurrence targeted 26 organ systems. A total of 95 significant disproportionality PTs conforming to the four algorithms were simultaneously retained. Rare reports and significant signals of aortic disease have emerged. Unexpected significant AEs such as scrotal swelling, scrotal ulcers, infections, and infestations might also occur. The median onset time of axitinib-associated AEs was 63.5 days (interquartile range [IQR] 20–182 days), and most of the cases occurred within the first one and 2 months after axitinib initiation. Our study found potential new AEs signals and might provide important support for clinical monitoring and risk identification of axitinib.
