Abstract
Abrocitinib (Cibinqo®) is an oral small-molecule inhibitor of Janus kinase 1 (JAK1) being developed by Pfizer for the treatment of moderate-to-severe atopic dermatitis (AD). In September 2021, abrocitinib was approved in the UK and Japan for the treatment of moderate-to-severe AD in adults and adolescents 12 years and older who are candidates for systemic therapy. Abrocitinib has also received a positive CHMP opinion in the EU for the treatment of moderate-to-severe atopic dermatitis in adults who are candidates for systemic therapy. Regulatory applications for the drug have also been submitted for review to several other countries, including the USA and Australia. This article summarizes the milestones in the development of abrocitinib leading to this first approval for the treatment of moderate-to-severe AD.© Springer Nature Switzerland AG 2021

description: The aim of this article is to analyse the convinction that the possession of language is the necessary condition to obtain a moral status. We shall offer some counterexamples to the Cartesian view according to which language is the conditio sine qua non in order to gain moral consideration, a position that characterised many of the contemporary approaches to ethics.

description: Multiple-input multiple-output (MIMO) wireless transmission imposes huge challenges on the design of efficient hardware architectures for iterative receivers. A major challenge is soft-input soft-output (SISO) MIMO demapping, often approached by sphere decoding (SD). In this paper, we introduce the - to our best knowledge - first VLSI architecture for SISO SD applying a single tree-search approach. Compared with a soft-output-only base architecture similar to the one proposed by Studer et al. in IEEE J-SAC 2008, the architectural modifications for soft input still allow a one-node-per-cycle execution. For a 4x4 16-QAM system, the area increases by 57% and the operating frequency degrades by 34% only.

description: We formulate and study a decentralized multi-armed bandit (MAB) problem. There are M distributed players competing for N independent arms. Each arm, when played, offers i.i.d. reward according to a distribution with an unknown parameter. At each time, each player chooses one arm to play without exchanging observations or any information with other players. Players choosing the same arm collide, and, depending on the collision model, either no one receives reward or the colliding players share the reward in an arbitrary way. We show that the minimum system regret of the decentralized MAB grows with time at the same logarithmic order as in the centralized counterpart where players act collectively as a single entity by exchanging observations and making decisions jointly. A decentralized policy is constructed to achieve this optimal order while ensuring fairness among players and without assuming any pre-agreement or information exchange among players. Based on a Time Division Fair Sharing (TDFS) of the M best arms, the proposed policy is constructed and its order optimality is proven under a general reward model. Furthermore, the basic structure of the TDFS policy can be used with any order-optimal single-player policy to achieve order optimality in the decentralized setting. We also establish a lower bound on the system regret growth rate for a general class of decentralized polices, to which the proposed policy belongs. This problem finds potential applications in cognitive radio networks, multi-channel communication systems, multi-agent systems, web search and advertising, and social networks.

High and anomalous thermal conductivity in monolayer MSi$_2$Z$_4$ semiconductors

description: The lattice thermal conductivity ($κ$) of newly synthesized two-dimensional (2D) MoSi$_2$N$_4$ family and its associated abnormality is anatomized by $ab$ $initio$ phonon Boltzmann transport calculations. $κ$ of MoSi$_2$N$_4$ and WSi$_2$N$_4$ is found over 400 Wm$^{-1}$K$^{-1}$ at 300 K. $κ$ of MoSi$_2$Z$_4$ (Z=N,P,As) obeys Slack's rule of thumb, decreasing by one order of magnitude from Z=N to Z=As with 46 Wm$^{-1}$K$^{-1}$. However, in MSi$_2$N$_4$ (M=Mo,Cr,W,Ti,Zr,Hf), the variation of $κ$ with respect to M is anomalous, i.e. deviating from Slack's classic rule. For M in the same group, $κ$ of MSi$_2$N$_4$ is insensitive to the average atomic mass, Debye temperature, phonon group velocity, and bond strength owing to the similar phonon structure and scattering rates. MSi$_2$N$_4$ with heavy group-VIB M even possesses a three to four times higher $κ$ than that with light group-IVB M, due to its much stronger M-N and exterior Si-N bonds and thus one order of magnitude lower phonon scattering rates. Nevertheless, this abnormality could be traced to an interplay of certain basic vibrational properties including the bunching strength and flatness of acoustic branches and their nearby optical branches, which lie outside of the conventional guidelines by Slack. This work predicts high $κ$ of 2D MSi$_2$Z$_4$ for thermal management and provides microscopic insight into deciphering the anomalous $κ$ of layered 2D structures.

Mechanisms of jet formation on the giant planets

Publisher: name: arXiv
Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The giant planet atmospheres exhibit alternating prograde (eastward) and retrograde (westward) jets of different speeds and widths, with an equatorial jet that is prograde on Jupiter and Saturn and retrograde on Uranus and Neptune. The jets are variously thought to be driven by differential radiative heating of the upper atmosphere or by intrinsic heat fluxes emanating from the deep interior. But existing models cannot account for the different flow configurations on the giant planets in an energetically consistent manner. Here a three-dimensional general circulation model is used to show that the different flow configurations can be reproduced by mechanisms universal across the giant planets if differences in their radiative heating and intrinsic heat fluxes are taken into account. Whether the equatorial jet is prograde or retrograde depends on whether the deep intrinsic heat fluxes are strong enough that convection penetrates into the upper troposphere and generates strong equatorial Rossby waves there. Prograde equatorial jets result if convective Rossby wave generation is strong and low-latitude angular momentum flux divergence owing to baroclinic eddies generated off the equator is sufficiently weak (Jupiter and Saturn). Retrograde equatorial jets result if either convective Rossby wave generation is weak or absent (Uranus) or low-latitude angular momentum flux divergence owing to baroclinic eddies is sufficiently strong (Neptune). The different speeds and widths of the off-equatorial jets depend, among other factors, on the differential radiative heating of the atmosphere and the altitude of the jets, which are vertically sheared. The simulations have closed energy and angular momentum balances that are consistent with observations of the giant planets.

Helicity cascades in rotating turbulence

description: The effect of helicity (velocity-vorticity correlations) is studied in direct numerical simulations of rotating turbulence down to Rossby numbers of 0.02. The results suggest that the presence of net helicity plays an important role in the dynamics of the flow. In particular, at small Rossby number, the energy cascades to large scales, as expected, but helicity then can dominate the cascade to small scales. A phenomenological interpretation in terms of a direct cascade of helicity slowed down by wave-eddy interactions leads to the prediction of new inertial indices for the small-scale energy and helicity spectra.

description: Attempting to fully exploit the rich information of topological structure and node features for attributed graph, we introduce self-supervised learning mechanism to graph representation learning and propose a novel Self-supervised Consensus Representation Learning (SCRL) framework. In contrast to most existing works that only explore one graph, our proposed SCRL method treats graph from two perspectives: topology graph and feature graph. We argue that their embeddings should share some common information, which could serve as a supervisory signal. Specifically, we construct the feature graph of node features via k-nearest neighbor algorithm. Then graph convolutional network (GCN) encoders extract features from two graphs respectively. Self-supervised loss is designed to maximize the agreement of the embeddings of the same node in the topology graph and the feature graph. Extensive experiments on real citation networks and social networks demonstrate the superiority of our proposed SCRL over the state-of-the-art methods on semi-supervised node classification task. Meanwhile, compared with its main competitors, SCRL is rather efficient.

The NHS workforce plan predicts a significant increase in the number of medical students over the next few years. How are we going to accommodate this increase in learners in an already busy clinical environment with a workforce that are feeling increasingly burdened?

The programme was designed to reduce the teaching burden on clinical colleagues whilst providing an improved educational experience for students on clinical placement. The hope is that Inreach can be used as a way of increasing placement capacity in future.

We endow the polynomial ring ${\mathbb C} [x_1,\ldots\\\ldots, x_n]$ with a structure of module over the Weyl algebra associated with the ring ${\mathbb C} [x_1,\ldots,x_n]^{W}$ of invariant polynomials under a reflections group $W$ of type $B_n$. Then we study the polynomial representation of the ring of invariant differential operators under the reflections group $W$. We use the group representation theory namely the higher Specht polynomials associated with the reflection group $W$ and establish a decomposition of that structure by providing explicitly the generators of the simple components.

description: We have investigated the electronic structure of LaFeAsO$_{1-x}$F$_{x}$ (x = 0; 0.1; 0.2) by angle-integrated photoemission spectroscopy and local density approximation (LDA) based band structure calculations. The valence band consists of a low energy peak at E = -0.25 eV and a broad structure around E = -5 eV in qualitative agreement with LDA. From the photon energy dependence of these peaks we conclude that the former derives almost exclusively from Fe 3d states. This constitutes experimental evidence for the strong iron character of the relevant states in a broad window around EF and confirms theoretical predictions.

description: In order to improve the adhesion of the joined layers of bimetallic materials, a method of applying an intermediate layer of powder to their contacting surfaces by gas-dynamic spraying was proposed. Foundry aluminum alloy AK9h was used for the base material. The working layer was sintered powder material on the basis of iron ANS100.29. Powders of different composition were used as an intermediate activating layer. Technological recommendations on the thickness of the sprayed layer are given. The strength of the layers' joining and metallographic studies of their joining zone on samples in the form of a bimetallic disk were carried out.

description: Given an arbitrary bitstream, we consider the problem of finding the longest substring whose ratio of ones to zeroes equals a given value. The central result of this paper is an algorithm that solves this problem in linear time. The method involves (i) reformulating the problem as a constrained walk through a sparse matrix, and then (ii) developing a data structure for this sparse matrix that allows us to perform each step of the walk in amortised constant time. We also give a linear time algorithm to find the longest substring whose ratio of ones to zeroes is bounded below by a given value. Both problems have practical relevance to cryptography and bioinformatics.

description: The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the pi- pi- pi+ final state using a 190 GeV/c pion beam hitting a lead target. A partial wave analysis has been performed on a sample of 420000 events taken at values of the squared 4-momentum transfer t' between 0.1 and 1 GeV^2/c^2. The well-known resonances a1(1260), a2(1320), and pi2(1670) are clearly observed. In addition, the data show a significant natural parity exchange production of a resonance with spin-exotic quantum numbers J^PC = 1-+ at 1.66 GeV/c^2 decaying to rho pi. The resonant nature of this wave is evident from the mass-dependent phase differences to the J^PC = 2-+ and 1++ waves. From a mass-dependent fit a resonance mass of 1660 +- 10+0-64 MeV/c^2 and a width of 269+-21+42-64 MeV/c^2 is deduced.

description: The low-temperature ferroelectric polarization of multiferroic $YMn_2O_5$ is completely reversed at a critical pressure of 10 kbar and the phase transition from the incommensurate to the commensurate magnetic phase is induced by pressures above 14 kbar. The high-pressure data correlate with thermal expansion measurements indicating a significant lattice strain at the low-temperature transition into the incommensurate phase. The results support the exchange striction model for the ferroelectricity in multiferroic $RMn_2O_5$ compounds and they show the importance of magnetic frustration as well as the spin-lattice coupling.

description: Recently, several experiments reported a muon deficit in air shower simulations with respect to the data. This problem can be studied using an estimator that quantifies the relative muon content of the data with respect to those of proton and iron Monte Carlo air shower simulations. We analyze two estimators. The first one, based on the logarithm of the mean of the muon content, is built from experimental considerations. It is ideal for comparing results from different experiments as it is independent of the detector resolution. The second estimator is based on the mean of the logarithm of the muon content, which implies that it depends on shower-to-shower fluctuations. It is linked to the mean-logarithmic mass $\left \langle \ln A \right \rangle$ through the Heitler-Matthews model. We study the properties of the estimators and their biases considering the knowns and unknowns of typical experiments. Furthermore, we study these effects in measurements of the muon density at $1000\,$m from the shower axis obtained by the Akeno Giant Air Shower Array (AGASA). Finally, we report the estimates of the relative muon content of the AGASA data, which support a muon deficit in simulations. These estimates constitute valuable additional information of the muon content of air showers at the highest energies.

Origins of social exchange
Creators: name: Lucas, Robert Gillmor
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this thesis was to identify and critically analyze the existing theoretical origins of social exchange. The identification and analysis of theoretically proposed origins of exchange was based on a thorough review of the works of the better known social exchange theorists. In the course of the review and analysis, it was discovered that social exchange theory consists of two distinguishable bodies of literature. Further, each of the two bodies of literature proceeds from its own assumptions concerning the nature and extent of social exchange activity, including the origins of such activity. Critical analysis revealed the possibility of the construction of a unified, more parsimonious conception of the origins of social exchange. The concept of social solidarity and its role as both causal agent and social result of exchange, processes provided the basis for a new explanation of the origins of social exchange. The general conclusions of the thesis are four. First, two models of social exchange exist in the literature. They are the generalized model and restricted model. Second, the origins of exchange assumed by each model differ. The generalized model posits the functional requirements of the group for integration and survival as origins. The restricted model posits psychological needs and/or rational economic motives as origins. Third, the generalized exchange model is capable of subsuming the restricted exchange model, at least insofar as origins of exchange are concerned. Fourth, it is concluded that both the restricted and generalized exchange models are linked in one crucial way. Both models implicitly deal with the creation of social solidarity, and the way in which the models are related through the concept of social solidarity is explained.

description: The Horizon-10T collaboration \cite{Beisembaev:2016cyg,2017EPJWC.14514001B,Beznosko:2019cI,2019EPJWC.20806002B,Beisembaev:2019nzd} have reported observation of Multi-Modal Events (MME) containing multiple peaks suggesting their clustering origin. These events are proven to be hard to explain in terms of conventional cosmic rays (CR). We propose that these MMEs might be result of the dark matter annihilation events within the so-called axion quark nugget (AQN) dark matter model, which was originally invented for completely different purpose to explain the observed similarity between the dark and the visible components in the Universe, i.e. $Ω_{\rm DM}\sim Ω_{\rm visible}$ without any fitting parameters. We support this proposal by demonstrating that the observations \cite{Beisembaev:2016cyg,2017EPJWC.14514001B,Beznosko:2019cI,2019EPJWC.20806002B,Beisembaev:2019nzd}, including the frequency of appearance, intensity, the spatial distribution, the time duration, the clustering features, and many other properties nicely match the emission characteristics of the AQN annihilation events in atmosphere. We list a number of features of the AQN events which are very distinct from conventional CR air showers. The observation (non-observation) of these features may substantiate (refute) our proposal.

description: We study large scale structure in the cosmology of Coleman-de Luccia bubble collisions. Within a set of controlled approximations we calculate the effects on galaxy motion seen from inside a bubble which has undergone such a collision. We find that generically bubble collisions lead to a coherent bulk flow of galaxies on some part of our sky, the details of which depend on the initial conditions of the collision and redshift to the galaxy in question. With other parameters held fixed the effects weaken as the amount of inflation inside our bubble grows, but can produce measurable flows past the number of efolds required to solve the flatness and horizon problems.

description: Shape-changing interfaces are promising for users to change the physical properties of common objects. However, prevailing approaches of actuation devices require either professional equipment or materials that are not commonly accessible to non-professional users. In this work, we focus on the controllable soft actuators with inflatable structures because they are soft thus safe for human computer interaction. We propose a soft actuator design, called xBalloon, that is workable, inexpensive and easy-to-fabricate. It consists of daily materials including balloons and plastics and can realize bending actuation very effectively. For characterization, we fabricated xBalloon samples with different geometrical parameters and tested them regarding the bending performance and found the analytical model describing the relationship between the shape and the bending width. We then used xBalloons to animate a series of common objects and all can work satisfactorily. We further verified the user experience about the the fabrication and found that even those with no prior robotic knowledge can fabricate xBalloons with ease and confidence. Given all these advantages, we believe that xBalloon is an ideal platform for interaction design and entertainment applications.

description: We present a feasibility study of a method to measure the cosine of twice the CKM Unitarity Triangle angle beta using a time-dependent Dalitz plot analysis of B0 -> D pi+ pi- decays, where the neutral D meson is reconstructed in decays to CP eigenstates. We show that this method can be used at the B factories to make a measurement of cos(2beta) that is competitive with, or more precise than, other techniques using different quark-level transitions, while sin(2beta) can be measured to an accuracy more precise than any existing measurement using b -> c ubar d transitions. Furthermore, this technique has great potential to be employed at LHCb.

description: Environmental DNA, eDNA, is considered today as an essential tool for the efficient detection of pathogens in aquatic environments, providing major benefits for monitoring fish health and controlling diseases in aquaculture. This experiment tests and analyzes the effects of different storage conditions on the eDNA recovery rates of two key salmon pathogens:Yersinia ruckeri, (Y.ruc) and Aeromonas salmonicida, (A.sal). These pathogens are among the common ones found in aquatic environments and are responsible for enteric redmouth disease and furunculosis, respectively. Moreover, they have significant impacts on salmon populations and aquaculture operations.

The main goals of this research were to evaluate how different storage temperatures, preservation solutions, and time intervals between filtration and testing the eDNA integrity affect the recovery rates of these two pathogens. Yersinia and Aeromonas were grown and cultured in their respective media in the laboratory. After undergoing filtration, a set of the filter papers containing the different concentrations of the pathogens underwent extraction followed by a quantitative Polymerase Chain (qPCR) and the Cq values obtained are considered as the reference value. The other filter papers were subjected to different storage conditions, including temperatures of 20°C (room temperature of the laboratory) and -20°C, preservation with 80% ethanol and time intervals of 1 day, 3 days, 7 days, 10 days and 14 days for Yersinia and only 7 days, 10 days and 14 days for Aeromonas. This difference in time interval was due to a contamination problem when growing A.sal. After the time interval, eDNA was extracted using established protocols and quantified using qPCR. They are then compared to the reference value and their respective standard series values to evaluate the impact of these variables on eDNA recovery.

After experimentation, results showed that the lower storage temperature greatly improved eDNA stability and recovery rates for Yersinia and Aeromonas. Preservation with ethanol also enhanced eDNA integrity, particularly for samples stored at lower temperatures. The study found that the time between sample filtration and processing is also a major factor, with significant eDNA degradation occurring in unpreserved samples stored at room temperature for more than 24 hours. These findings provide important information concerning the optimal storage conditions for eDNA samples, which can increase the efficiency and reliability of eDNA-based pathogen detection techniques. By testing and studying the best techniques and processes for sample preservation, this research supports the effective monitoring and control of fish health in both natural and aquaculture environments.
