description: Aims: Cladribine tablets is the first oral short-course treatment approved for highly active relapsing multiple sclerosis (MS). The Association of British Neurologists guidelines currently recommend two infusion therapies, alemtuzumab and natalizumab, to treat high disease activity relapsing remitting MS (HDA-RRMS). This analysis assessed the cost-effectiveness of cladribine tablets in HDA-RRMS compared with alemtuzumab and natalizumab, from the perspective of the National Health Service (NHS) in England. Materials and Methods: A cohort-based Markov model with 11 health states (10 Expanded Disability Status Scale [EDSS] plus death) was developed. Transition matrices from the British Columbia registry were used to model the natural history of EDSS. Treatment effect on EDSS was modelled using hazard ratios for 6-month confirmed disability progression from an indirect treatment comparison (ITC). Relapses and drug-related adverse events were modelled via annualized relapse rates and event probabilities, with associated costs and quality-adjusted life year (QALY) losses. Utilities were derived from trials and the literature, and costs from NHS and literature sources. Uncertainty was assessed via probabilistic and deterministic sensitivity analyses. Results: Cladribine tablets was dominant (i.e., less costly and more effective) versus alemtuzumab and natalizumab in pairwise comparisons, and the dominant strategy in fully incremental analyses. Incremental cost was driven largely by drug acquisition and administration costs, and incremental QALY gain largely by differences in delayed EDSS progression. Cladribine tablets had a 93% probability of being cost-effective at a threshold of GBP 30,000 per QALY gained, and remained dominant across the scenario analyses tested. The greatest influence on results was the treatment effect on disability progression derived from the ITC. Limitations: Uncertainty over the efficacy of DMT beyond trial durations. In line with other comparative effectiveness analyses, the network meta-analysis informing this cost-effectiveness analysis was associated with a degree of uncertainty. No treatment switching analyses were undertaken. Conclusions: Cladribine tablets are a cost-effective alternative to alemtuzumab and natalizumab in the treatment of HDA-RRMS from the perspective of the NHS in England.

description: This paper considers a demand response agent that must find a near-optimal sequence of decisions based on sparse observations of its environment. Extracting a relevant set of features from these observations is a challenging task and may require substantial domain knowledge. One way to tackle this problem is to store sequences of past observations and actions in the state vector, making it high dimensional, and apply techniques from deep learning. This paper investigates the capabilities of different deep learning techniques, such as convolutional neural networks and recurrent neural networks, to extract relevant features for finding near-optimal policies for a residential heating system and electric water heater that are hindered by sparse observations. Our simulation results indicate that in this specific scenario, feeding sequences of time-series to an LSTM network, which is a specific type of recurrent neural network, achieved a higher performance than stacking these time-series in the input of a convolutional neural network or deep neural network.

description: We present a 200 ksec Chandra observation of seven spectroscopically selected, high redshift (0.75 < z < 1.03) galaxy groups and clusters discovered by the DEEP2 Galaxy Redshift Survey in the Extended Groth Strip (EGS). X-ray emission at the locations of these systems is consistent with background. The 3-sigma upper limits on the bolometric X-ray luminosities (L_X) of these systems put a strong constraint on the relation between L_X and the velocity dispersion of member galaxies sigma_gal at z~1; the DEEP2 systems have lower luminosity than would be predicted by the local relation. Our result is consistent with recent findings that at high redshift, optically selected clusters tend to be X-ray underluminous. A comparison with mock catalogs indicates that it is unlikely that this effect is entirely caused by a measurement bias between sigma_gal and the dark matter velocity dispersion. Physically, the DEEP2 systems may still be in the process of forming and hence not fully virialized, or they may be deficient in hot gas compared to local systems. We find only one possibly extended source in this Chandra field, which happens to lie outside the DEEP2 coverage.

description: We consider the problem of registering (aligning) two images to sub-pixel accuracy by optimization of objective functions constructed from the images' intensity values. We show that some widely used interpolation methods can introduce multiple local optima in the energy of the interpolated image which, if not counter-balanced by other terms, can cause local optima in registration objective functions including the sum of squared differences, cross correlation, and mutual information. We discuss different solutions to address the problem based on high degree B-spline interpolation, low pass filtering the images, and stochastic integration. Numerical examples using synthetic and real signals and images are shown.

description: The purpose of this paper is to study some new concrete approximation processes for continuous vector-valued mappings defined on the infinite dimensional cube or on a subset of a real Hilbert space. In both cases these operators are modelled on classical Bernstein polynomials and represent a possible extension to an infinite dimensional setting. The same idea is generalized to obtain from a given approximation process for function defined on a real interval a new approximation process for vector-valued mappings defined on subsets of a real Hilbert space.

description: We examine the history of the loss and replenishment of the Martian atmosphere using elemental and isotopic compositions of nitrogen and noble gases. The evolution of the atmosphere is calculated by taking into consideration various processes: impact erosion and replenishment by asteroids and comets, atmospheric escape induced by solar radiation and wind, volcanic degassing, and gas deposition by interplanetary dust particles. Our model reproduces the elemental and isotopic compositions of N and noble gases (except for Xe) in the Martian atmosphere, as inferred from exploration missions and analyses of Martian meteorites. Other processes such as ionization-induced fractionation, which are not included in our model, are likely to make a large contribution in producing the current Xe isotope composition. Since intense impacts during the heavy bombardment period greatly affect the atmospheric mass, the atmospheric pressure evolves stochastically. Whereas a dense atmosphere preserves primitive isotopic compositions, a thin atmosphere on early Mars is severely influenced by stochastic impact events and following escape-induced fractionation. The onset of fractionation following the decrease in atmospheric pressure is explained by shorter timescales of isotopic fractionation under a lower atmospheric pressure. The comparison of our numerical results with the less fractionated N ($^15$N/$^14$N) and Ar ($^38$Ar/$^36$Ar) isotope compositions of the ancient atmosphere recorded in the Martian meteorite Allan Hills 84001 provides a lower limit of the atmospheric pressure in 4 Ga to preserve the primitive isotopic compositions. We conclude that the atmospheric pressure was higher than approximately 0.5 bar at 4 Ga.

CP-violating asymmetries in B^0 decays to K^+K^-K_{S(L)}^0 and K_S^0K_S^0K_{S(L)}^0

description: Decay rates and time-dependent and direct CP asymmetries in the decays $B^0\to K^+K^-K_{S(L)}$ and $K_S K_S K_{S(L)}$ are studied. Resonant and nonresonant contributions to the three-body decays are carefully investigated. Nonresonant effects on 2-body and 3-body matrix elements are constrained by QCD counting rules. The predicted branching ratios are consistent with the data within the theoretical and experimental errors, though the theoretical central values are somewhat smaller than the experimental ones. Owing to the presence of color-allowed tree amplitudes in $B^0\to K^+K^-K_{S(L)}$, this penguin-dominated mode is subject to a significant tree pollution and the deviation of the mixing-induced \CP asymmetry from that measured in $B\to J/ψK_S$, namely, $Δ\sin 2β_{K^+K^-K_{S(L)}}\equiv \sin 2β_{K^+K^-K_{S(L)}}-\sin 2 β_{J/ψK_S}$, can be as large as O(0.10). In contrast, the $K_SK_SK_{S(L)}$ modes appear theoretically very clean in our picture with negligible $Δ\sin 2β_{K_SK_SK_{S(L)}}$. Direct CP asymmetries in $K^+K^-K_{S(L)}$ and $K_S K_S K_{S(L)}$ modes are found to be very small.

description: The local atomic structure of superconducting NdO$_{1-x}$F$_{x}$BiS$_{2}$ ($x$=0.2 and 0.4) is investigated using neutron diffraction and the pair density function analysis technique. In the non-superconducting $x$=0.2 composition, ferrodistortive displacements of the pyramidal sulfur ions break the tetragonal symmetry and a superlattice structure emerges with peaks appearing at $h+k$ odd reflections superimposed on the even reflections of the $P4/nmm$ symmetry. In the superconducting $x$=0.4 composition, similar ferrodistortive displacements are observed but with different magnitudes coupled with in-plane Bi distortions. The distortions are indicative of charge fluctuations that may lead to charge localization and suppression of superconductivity.

If ϕis a positive weight such that -L_pϕ>= 0, then the Hardy type inequality c\int_Ω\frac{\abs u^p}{ϕ^p}\abs{\nabla_L ϕ}^p dξ\le \int_Ω\abs{\nabla_L u}^p dξholds. We find an explicit value of the constant involved, which, in most cases, results optimal. As particular case we derive Hardy inequalities for subelliptic operators on Carnot Groups.

description: The traditional gambling industry has been and still is currently under disruption caused by the more and more influential, regulated and commercially still fast increasing phenomena: online gambling. This trend has been even strengthened due to the Covid crisis, as soon as offline casino and gambling operators had to close their terrestrial venues. Not only traditional gambling operators, like casinos and/or slot arcades operators are facing this significant competition today, although gaming regulators, legislators and gambling technology providers,have to adopted permanently to this new situation. The online gambling segment has therefore nowadays a strong influence on the general players demands and behaviors, the product and game life cycles and also impact to and in terms of the innovation cultures of the traditional gambling technology providers. Technology casino and gambling providers are more or less having traditionally a closed innovation culture and environment. This master thesis objective is in particular, to find out and describe potential innovation related tensions and challenges,which are resulting from the effects and influence of the online gaming environment to the traditional gambling and casino industry. Furthermore, to see how the theoretical research results and its conclusions, do or do not match with the practical research conducted within that master thesis. On the practical part, a qualitative and inductive case study related to the objective has been conducted, with the aim to establish a grounded theory based in particularon the Gioia-methodology. The interviews were held mainly with stakeholders from an integrated global gambling industry giant, having actively both business segments, meaning the online and the offline part of the industry (B2B and B2C), within its group. The case study and its grounded theory shows, that most of the challenges and tensions resulting from the“clash” of cultures within the gambling industry and the case study example, are mainly placed within the internal space and therefore to be potentially solved primarily internally. The author proposes specific and concrete situative solutions for the challenges of the respective industry and company, in which the case study was conducted and outlines further, certain academic research topics, in particular when it comes to questions concerning business and innovation strategies and innovation matters related to acquisitions and mergers of traditional gambling operators/technology providers with online gaming actors and other entertainment corporations.

description: Decoherence originates from the leakage of quantum information into external degrees of freedom. For a qubit the two main decoherence channels are relaxation and dephasing. Here, we report an experiment on a superconducting qubit where we retrieve part of the lost information in both of these channels. We demonstrate that raw averaging the corresponding measurement records provides a full quantum tomography of the qubit state where all three components of the effective spin-1/2 are simultaneously measured. From single realizations of the experiment, it is possible to infer the quantum trajectories followed by the qubit state conditioned on relaxation and/or dephasing channels. The incompatibility between these quantum measurements of the qubit leads to observable consequences in the statistics of quantum states. The high level of controllability of superconducting circuits enables us to explore many regimes from the Zeno effect to underdamped Rabi oscillations depending on the relative strengths of driving, dephasing and relaxation.

description: We present a detailed analysis of the intrinsic absorption in the Seyfert 1 galaxy NGC 4151 using UV spectra from the HST/STIS and FUSE, obtained 2002 May as part of a set of contemporaneous observations that included Chandra/HETGS spectra. In our analysis of the Chandra spectra, we determined that the soft X-ray absorber was the source of the saturated UV lines of O VI, C IV, and N V associated with the absorption feature at a radial velocity of ~ -500 km/sec, which we referred to as component D+E. In the present work, we have derived tighter constrains on the the line-of-sight covering factors, densities, and radial distances of the absorbers. We find that the Equivalent Widths (EWs) of the low-ionization lines associated with D+E varied over the period from 1999 July to 2002 May. The drop in the EWs of these lines between 2001 April and 2002 May are suggestive of bulk motion of gas out of our line-of-sight. If these lines from these two epochs arose in the same sub-component, the transverse velocity of the gas is ~ 2100 km/sec. Transverse velocities of this order are consistent with an origin in a rotating disk, at the roughly radial distance we derived for D+E.

description: We use soft-collinear effective theory (SCET) to study the factorization properties of deep inelastic scattering in the region of phase space where 1-x = O(Lambda_{QCD/Q}). By applying a regions analysis to loop diagrams in the Breit frame, we show that the appropriate version of SCET includes anti-hard-collinear, collinear, and soft-collinear fields. We find that the effects of the soft-collinear fields spoil perturbative factorization even at leading order in the 1/Q expansion.

description: Biological shape modeling is an essential task that is required for systems biology efforts to simulate complex cell behaviors. Statistical learning methods have been used to build generative shape models based on reconstructive shape parameters extracted from microscope image collections. However, such parametric modeling approaches are usually limited to simple shapes and easily-modeled parameter distributions. Moreover, to maximize the reconstruction accuracy, significant effort is required to design models for specific datasets or patterns. We have therefore developed an instance-based approach to model biological shapes within a shape space built upon diffeomorphic measurement. We also designed a recursive interpolation algorithm to probabilistically synthesize new shape instances using the shape space model and the original instances. The method is quite generalizable and therefore can be applied to most nuclear, cell and protein object shapes, in both 2D and 3D.

description: The success or failure of left ventricular assist device (LVAD) therapy can be measured in several ways. The landmark clinical trials, REMATCH1 and INTrEPID,2defined success in terms of mortality and morbidity, compared with standard medical therapy. Indeed, these are the primary benchmarks used by the US Food and Drug Agency when evaluating a device for market approval. On a grander scale, success may be measured in terms of the popularity or use of the therapy. In this respect, LVAD therapy could be deemed as an abject failure. Thirty years ago, the Office of Technology Assessment projected the annual need to be on the order of 100,000 in the United States and 200,000 worldwide3; yet the current rate of LVAD implantation has yet to achieve 5% of this target.

description: In a higher-order modified teleparallel theory cosmological we present analytical cosmological solutions. In particular we determine forms of the unknown potential which drives the scalar field such that the field equations form a Liouville integrable system. For the determination of the conservation laws we apply the Cartan symmetries. Furthermore, inspired from our solutions, a toy model is studied and it is shown that it can describe the Supernova data, while at the same time introduces dark matter components in the Hubble function. When the extra matter source is a stiff fluid then we show how analytical solutions for Bianchi I universes can be constructed from our analysis. Finally, we perform a global dynamical analysis of the field equations by using variables different from that of the Hubble-normalization.

description: We have reanalysed the ASCA X-ray spectrum of the bright symbiotic star CH Cyg, which exhibits apparently distinct hard and soft X-ray components. Our analysis demonstrates that the soft X-ray emission can be interpreted as scattering of the hard X-ray component in a photo-ionised medium surrounding the white dwarf. This is in contrast to previous analyses in which the soft X-ray emission was fitted separately and assumed to arise independently of the hard X-ray component. We note the striking similarity between the X-ray spectra of CH Cyg and Seyfert 2 galaxies, which are also believed to exhibit scattering in a photo-ionised medium.

Inferring dissipation from the violation of Fluctuation-Dissipation Theorem

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The Harada-Sasa equality elegantly connects the energy dissipation rate of a moving object with its measurable violation of the Fluctuation-Dissipation Theorem (FDT). Although proven for Langevin processes, its validity remains unclear for discrete Markov systems whose forward and backward transition rates respond asymmetrically to external perturbation. A typical example is a motor protein called kinesin. Here we show generally that the FDT violation persists surprisingly in the high-frequency limit due to the asymmetry, resulting in a divergent FDT violation integral and thus a complete breakdown of the Harada-Sasa equality. A renormalized FDT violation integral still well predicts the dissipation rate when each discrete transition produces a small entropy in the environment. Our study also suggests a new way to infer this perturbation asymmetry based on the measurable high-frequency-limit FDT violation.

description: Restituita dalla tomba Martini Marescotti a Cerveteri, l’anfora attica a figure nere del Pittore di Priamo conservata nel Museo Nazionale Etrusco di Villa Giulia mostra come decorazione principale una vendemmia con Dioniso e Satiri su un lato, e un gruppo di fanciulle nude impegnate nel bagno e nella cura del corpo in un ambiente naturale, contraddistinto dall’acqua, sull’altro. La rarità di quest’ultima scena ha reso l’anfora un punto di riferimento nello studio della donna nella società antica, sia per la dimensione del bagno che presuppone la nudità, sia per il rinvio al nuoto. Lo studio propone una nuova lettura delle immagini nel loro complesso, alla luce del contesto storico-culturale nel quale il vaso è stato prodotto.

Found in the Martini Marescotti tomb in Cerveteri, the Attic black-figure amphora by the Priam Painter preserved in the National Etruscan Museum of Villa Giulia, shows as its main decoration a grape harvest with Dionysus and Satyrs on one side, and a group of nude maidens engaged in bathing and body care in a natural environment marked by water on the other. The rarity of the latter scene has made the amphora a point of reference in the study of women in ancient society, both for the dimension of bathing that presupposes nudity and for the reference to swimming. The study proposes a new interpretation of the images as a whole, in the light of the historical-cultural context in which the vase was produced.

description: The meaningful specific anisotropy in the angle distribution of leptons with respect to the three-momentum of pair is predicted as a feasibility signature of synchrotron-like mechanism resulting from the quarks interacting with a collective confining color field in the heavy ion collisions. The lepton pair production rate and the spectrum of pair invariant mass are presented for this new dilepton source that is apparently not taken into consideration in the available phenomenological estimates.

description: BACKGROUND: Previous thoracic artificial lungs (TALs) had blood flow impedance greater than that of the natural lungs, which could cause abnormal pulmonary hemodynamics. New compliant TALs (cTALs), however, have an impedance lower than that of the natural lung. METHODS: In this study, a cTAL of new design was attached between the pulmonary artery (PA) and the left atrium (LA) in 5 sheep (60.2 ± 1.9 kg). A distal PA band was placed to control the percentage of cardiac output (CO) routed to the cTAL. Rest and exercise conditions were simulated using a continuous dobutamine infusion of 0 and 5 μg/kg/min, respectively. At each dose, a hemodynamic data set was acquired at baseline (no flow to the cTAL), and 60%, 75%, and 90% of CO was shunted to the cTAL. RESULTS: Device resistance did not vary with blood flow rate, averaging 0.51 ± 0.03 mm Hg/(L/min). Under all conditions, CO was not significantly different from baseline. Pulmonary system impedance increased above baseline only with 5 μg/kg/min of dobutamine and 90% of CO diverted to the cTAL. CONCLUSIONS: Results indicated minimal changes in pulmonary hemodynamics during PA-LA cTAL attachment for high device flows under rest and exercise conditions.

description: Topological insulators generally have dielectric bulk and conductive surface states. Consequently, some of these materials have been shown to support polaritonic modes at visible and THz frequencies. At the same time, the optical properties of topological insulators in the mid-infrared (IR) remain poorly investigated. We employ near-field imaging to probe the mid-IR response from the exfoliated flakes of bismuth (Bi) / selenide (Se) / telluride (Te) / antimony (Sb) crystals with varying stoichiometry - Bi2Se3, Bi2Te2Se, and Bi1.5Sb0.5Te1.7Se1.3 - in pristine form as well as covered by thin flakes of hexagonal boron nitride (hBN). Contrary to theoretical expectations, all three materials exhibit a dielectric response with a high refractive index and with a loss below the experimental detection limit. Particularly, the near-field mapping of propagating phonon-polaritons in hBN demonstrates that these van der Waals crystals act as a practically lossless dielectric substrate with an ultra-high refractive index of up to 7.5 in Bi2Te2Se. Such a unique dielectric crystal would be of great advantage for numerous nanophotonic applications in the mid-IR.

description: Ambient-pressure-grown LaO$_{0.5}$F$_{0.5}$BiS$_2$ with a superconducting transition temperature $T_{c}\sim$3K possesses a highly anisotropic normal state. By a series of electrical resistivity measurements with a magnetic field direction varying between the crystalline $c$-axis and the $ab$-plane, we present the first datasets displaying the temperature dependence of the out-of-plane upper critical field $H_{c2}^{\perp}(T)$, the in-plane upper critical field $H_{c2}^{\parallel}(T)$, as well as the angular dependence of $H_{c2}$ at fixed temperatures for ambient-pressure-grown LaO$_{0.5}$F$_{0.5}$BiS$_2$ single crystals. The anisotropy of the superconductivity, $H_{c2}^{\parallel}/H_{c2}^{\perp}$, reaches $\sim$16 on approaching 0 K, but it decreases significantly near $T_{c}$. A pronounced upward curvature of $H_{c2}^{\parallel}(T)$ is observed near $T_{c}$, which we analyze using a two-gap model. Moreover, $H_{c2}^{\parallel}(0)$ is found to exceed the Pauli paramagnetic limit, which can be understood by considering the strong spin-orbit coupling associated with Bi as well as the breaking of the local inversion symmetry at the electronically active BiS$_2$ bilayers. Hence, LaO$_{0.5}$F$_{0.5}$BiS$_2$ with a centrosymmetric lattice structure is a unique platform to explore the physics associated with local parity violation in the bulk crystal.

Modelling cross-correlations of ultra-high-energy cosmic rays and galaxies

description: The astrophysical engines that power ultra-high-energy cosmic rays (UHECRs) remain to date unknown. Since the propagation horizon of UHECRs is limited to the local, anisotropic Universe, the distribution of UHECR arrival directions should be anisotropic. In this paper we expand the analysis of the potential for the angular, harmonic cross-correlation between UHECRs and galaxies to detect such anisotropies. We do so by studying simulations performed assuming proton, oxygen and silicon injection models, each simulation containing a number of events comparable to a conservative estimate of currently available datasets, as well as by extending the analytic treatment of the magnetic deflections. Quantitatively, we find that, while the correlations for each given multipole are generally weak, (1) the total harmonic power summed over multipoles is detectable with signal-to-noise ratios well above~5 for both the auto-correlation and the cross-correlation (once optimal weights are applied) in most cases studied here, with peaks of signal-to-noise ratio around between~8 and~10 at the highest energies; (2) if we combine the UHECR auto-correlation and the cross-correlation we are able to reach detection levels of (3σ) and above for individual multipoles at the largest scales, especially for heavy composition. In particular, we predict that the combined-analysis quadrupole could be detected already with existing data.

description: I codici Leiden, Universiteitsbibliothek, Voss. Lat. F 63 (sec. X), f. Ir (U) e Firenze, Biblioteca Medicea Laurenziana, XXXV 8 (sec. XIII), f. 1v (L) tramandano un’anonima Vita Lucani che sembra non essere stata finora adeguatamente approfondita dagli studiosi. Questa Vita di età medievale, sebbene attinga certamente alle ben più note Vitae Lucani attribuite a Svetonio (sec. I d.C.) e a Vacca (sec. VI d.C.), rispetto a quest’ultime si sofferma dettagliatamente sulla vexata quaestio del finale incompiuto della Pharsalia. L’assenza di omogeneità nel trasmettere questo dato da parte dei due manoscritti che tramandano questa Vita Lucani (U: Nam mortem Pompeii atque Catonis descripsit e L: Nam mortem Catonis non descripsit) ha indotto gli studiosi o ad accogliere la frase tramandata dal manoscritto U o a congetturare la presenza di una lacuna dopo atque segnalandola con una crux desperationis. Partendo da tale premessa, scopo della presente indagine sarà avanzare una nuova proposta di lettura di quest’ultima frase, partendo da una nuova analisi del testo della Vita Lucani trasmessa dai codici U ed L e dagli eventuali rapporti di parentela intercorrenti tra questi due manoscritti.

The manuscripts Leiden, Universiteitsbibliothek, Voss. Lat. F 63 (10th century), f. Ir, (U) and Firenze, Biblioteca Medicea Laurenziana, XXXV 8 (13th century), f. 1v (L) hand down an anonymous Vita Lucani that seems not to have been adequately researched by scholars. This medieval Vita, although it certainly draws on the much better-known Vitae Lucani attributed to Suetonius (1st century AD) and Vacca (6th century AD), in comparison to these, dwells in detail on the vexata quaestio of the unfinished ending of the Pharsalia. The lack of homogeneity in the transmission of this datum by the two manuscripts that hand down this Vita Lucani (U: Nam mortem Pompeii atque Catonis descripsit and L: Nam mortem Catonis non descripsit) has led scholars either to accept the sentence handed down by the older manuscript U or to conjecture the presence of a gap after atque, marking it with a crux desperationis. Starting from this premise, the aim of the present research will be to put forward a new proposal for reading this last sentence, starting with a new analysis of the text of theVita Lucani transmitted by U and L and the possible relationship between these two manuscripts.
