description: We demonstrate theoretically that electric field can drive a quantum phase transition between band insulator to topological insulator in CdTe/HgCdTe/CdTe quantum wells. The numerical results suggest that the electric field could be used as a switch to turn on or off the topological insulator phase, and temperature can affect significantly the phase diagram for different gate voltage and compositions. Our theoretical results provide us an efficient way to manipulate the quantum phase of HgTe quantum wells.

description: We present the results obtained by a detailed study of the extragalactic Z source, LMC X-2, using broad band Suzaku data and a large ($ \sim 750$ ksec) data set obtained with the proportional counter array (PCA) onboard RXTE. The PCA data allows for studying the complete spectral evolution along the horizontal, normal and flaring branches of the Z-track. Comparison with previous study show that the details of spectral evolution (like variation of Comptonizing electron temperature), is similar to that of GX 17+2 but unlike that of Cyg X-2 and GX 349+2. This suggests that Z sources are heterogeneous group with perhaps LMC X-2 and GX 17+2 being member of a subclass. However non monotonic evolution of the Compton y-parameter seems to be generic to all sources. The broad band {\it Suzaku} data reveals that the additional soft component of the source modelled as a disk blackbody emission is strongly preferred over one where it is taken to be a blackbody spectrum. This component as well as the temperature of seed photons do not vary when source goes into a flaring mode and the entire variation can be ascribed to the Comptonizing cloud. The bolometric unabsorbed luminosity of the source is well constrained to be $ \sim 2.23 \times 10^{38}$ ergs/sec which if the source is Eddington limited implies a neutron star mass of 1.6 M$_\odot$. We discuss the implications of these results.

description: This thesis is concerned with Gaussian Process (GP) models for computer experiments with both numerical and categorical input variables. The Low-Rank Correlation kernel LRCr is introduced for the estimation of the cross-correlation matrix – i.e., the matrix that contains the correlations of the GP given different levels of a categorical variable. LRCr is a rank-r approximation of the real but unknown cross-correlation matrix and provides two advantages over existing parsimonious correlation kernels: First, it lets the practictioner adapt the number of parameters to be estimated according to the problem at hand by choosing an appropriate rank r. And second, the entries of the estimated cross-correlation matrix are not restricted to non-negative values. Moreover, an approach is presented that can generate a test function with mixed inputs from a test function having only continuous variables. This is done by discretizing (or “slicing”) one of its dimensions. Depending on the function and the slice positions, the slices sometimes happen to be highly positively correlated. By turning some slices in a specific way, the position and value of the global optimum can be preserved while changing the sign of a number of cross-correlations. With these methods, a simulation study is conducted that investigates the estimation accuracy of the cross-correlation matrices as well as the prediction accuracy of the response surface among different correlation kernels. Thereby, the number of points in the initial design of experiments and the amount of negative cross-correlations are varied in order to compare their impact on different kernels. We then focus on GP models with mixed inputs in the context of the Efficient Global Optimization (EGO) algorithm. We conduct another simulation study in which the distances of the different kernels' best found solutions to the optimum are compared. Again, the number of points in the initial experimental design is varied. However, the total budget of function evaluations is fixed. The results show that a higher number of EGO iterations tends to be preferable over a larger initial experimental design. Finally, three applications are considered: First, an optimization of hyperparameters of a computer vision algorithm. Second, an optimization of a logistics production process using a simulation model. And third, a bi-objective optimization of shift planning in a simulated high-bay warehouse, where constraints on the input variables must be met. These applications involve further challenges, which are successfully solved.

description: In this letter, we introduce a deep reinforcement learning (RL) based multi-robot formation controller for the task of autonomous aerial human motion capture (MoCap). We focus on vision-based MoCap, where the objective is to estimate the trajectory of body pose and shape of a single moving person using multiple micro aerial vehicles. State-of-the-art solutions to this problem are based on classical control methods, which depend on hand-crafted system and observation models. Such models are difficult to derive and generalize across different systems. Moreover, the non-linearity and non-convexities of these models lead to sub-optimal controls. In our work, we formulate this problem as a sequential decision making task to achieve the vision-based motion capture objectives, and solve it using a deep neural network-based RL method. We leverage proximal policy optimization (PPO) to train a stochastic decentralized control policy for formation control. The neural network is trained in a parallelized setup in synthetic environments. We performed extensive simulation experiments to validate our approach. Finally, real-robot experiments demonstrate that our policies generalize to real world conditions. Video Link: https://bit.ly/38SJfjo Supplementary: https://bit.ly/3evfo1O

An experimental study of the response of young Pacific salmon to sharp sea water gradients

Publisher: name: University of British Columbia
Year: 2012

description: The responses of chum and pink salmon fry, and coho salmon fry and smolts (Oncorhynchus keta, O. gorbuscha, and O. kisutch) to isotonic and hypertonic seawater were studied in sharp-gradient tanks to determine whether or not salinity gradients can act as directive agencies in the seaward migration of juvenile Pacific salmon. Chum and pink fry responded positively to both concentrations of seawater. Coho fry responded positively to isotonic seawater but did not respond positively to hypertonic seawater. Coho smolts responded positively to hypertonic seawater. Acclimation of chum fry to seawater prior to observation of their responses resulted in a reduction of their initial response although there was no significant change in the levels of response finally obtained. Major differences in the concentration of the acclimatory solutions did not affect the responses of this species to hypertonic seawater. The activity of chum and pink fry, and of coho smolts generally decreased on first entry into seawater. Observations on acclimated chum fry suggest that activity is related to osmotic control. Decreased activity may arise from the interaction of absorbed electrolytes on muscle protein. This effect continues until the commencement of osmoregulation when excess absorbed ions are removed from the muscles. The relatively high levels of activity observed in pink fry may be the result of hyperfunction of the thyroid gland, a condition related to osmotic stress in fresh water. The influence of sea water on the seaward movements of juvenile Pacific salmon is probably two-fold. The effects of absorbed electrolytes on motor activity may decrease the intensity of rheotrophic responses which would tend to keep the migrants in river mouths, while at the same time increasing the probability of passive displacement out to sea by current action. Active positive responses to salinity gradients enhance the likelihood of movement into the ocean. Control experiments indicated the operation of some factor or factors resulting in preference reactions by chum and pink fry and coho smolts for the tanks in which they had been originally placed. The possible influence of olfactory and visual cues on this preference reaction has been discussed.

description: We investigate the low temperature phase of three-dimensional Edwards-Anderson model with Bernoulli random couplings. We show that at a fixed value $Q$ of the overlap the model fulfills the clustering property: the connected correlation functions between two local overlaps decay as a power whose exponent is independent of $Q$ for all $0\le |Q| < q_{EA}$. Our findings are in agreement with the RSB theory and show that the overlap is a good order parameter.

We construct an example of a discrete set $Λ\subset \mathbb{R}$ (a small perturbation of the integers) for which no characterization of this kind is possible: there are two functions $f, g \in L^1(\mathbb{R})$ whose Fourier transforms have the same set of zeros, but such that $f + Λ$ is a tiling while $g + Λ$ is not.

description: As the era of gravitational-wave astronomy has well and truly begun, gravitational radiation from rotating neutron stars remains elusive. Rapidly spinning neutron stars are the main targets for continuous-wave searches since, according to general relativity, provided they are asymmetrically deformed, they will emit gravitational waves. It is believed that detecting such radiation will unlock the answer to why no pulsars have been observed to spin close to the break-up frequency. We review existing studies on the maximum mountain that a neutron star crust can support, critique the key assumptions and identify issues relating to boundary conditions that need to be resolved. In light of this discussion, we present a new scheme for modelling neutron star mountains. The crucial ingredient for this scheme is a description of the fiducial force which takes the star away from sphericity. We consider three examples: a source potential which is a solution to Laplace's equation, another solution which does not act in the core of the star and a thermal pressure perturbation. For all the cases, we find that the largest quadrupoles are between a factor of a few to two orders of magnitude below previous estimates of the maximum mountain size.

description: With the nearing completion of the first-generation experiments at asymmetric $e^+ e^-$ colliders running at the $Υ(4S)$ resonance ("B-Factories") a new era of high luminosity machines is at the horizon. We report here on the plans at KEK in Japan to upgrade the KEKB machine ("SuperKEKB") with the goal of achieving an instantaneous luminosity exceeding $8 \times 10^{35}$ cm$^{-2}$ s$^{-1}$, which is almost two orders of magnitude higher than KEKB. Together with the machine, the Belle detector will be upgraded as well ("Belle-II"), with significant improvements to increase its background tolerance as well as improving its physics performance. The new generation of experiments is scheduled to take first data in the year 2013.

description: To clarify superconductivity in EuFe2As2 hidden by antiferromagnetism of Eu2+, we investigated a Ca-substituted sample, Eu0.5Ca0.5Fe2As2, under high pressure. For ambient pressure, the sample exhibits a spin-density-wave (SDW) transition at TSDW = 191 K and antiferromagnetic order at TN = 4 K, but no evidence of superconductivity down to 2 K. The Ca-substitution certainly weakens the antiferromagnetism. With increasing pressure, TSDW shifts to lower temperature and becomes more unclear. Above 1.27 GPa, pressure-induced superconductivity with zero resistivity is observed at around Tc = 20 K. At 2.14 GPa, Tc reaches a maximum value of 24 K and the superconducting transition becomes the sharpest. These features of emergence of the superconductivity are qualitatively similar to those observed in AFe2As2 (A = Ba, Ca).

description: We show that an initially unpolarized electron flow acquires spin polarization after passing through a lateral barrier in two-dimensional (2D) system with spin-orbit interaction (SOI) even if the current is directed normally to the barrier. The generated spin current depends on the distance from the barrier. It oscillates with the distance in the vicinity of the barrier and asymptotically reaches a constant value. The most efficient generation of the spin current (with polarization above 50%) occurs, when the Fermi energy is near the potential barrier maximum. Since the spin current in SOI medium is not unambiguously defined we propose to pass this current from the SOI region into a contacting region without SOI and show, that the spin polarization loss under such transmission can be negligible.

Superfluidity of $Λ$ hyperons in neutron stars

description: We study the $^1S_0$ superfluidity of $Λ$ hyperons in neutron star matter and neutron stars. We use the relativistic mean field (RMF) theory to calculate the properties of neutron star matter. In the RMF approach, the meson-hyperon couplings are constrained by reasonable hyperon potentials that include the updated information from recent developments in hypernuclear physics. To examine the $^1S_0$ pairing gap of $Λ$ hyperons, we employ several $ΛΛ$ interactions based on the Nijmegen models and used in double-$Λ$ hypernuclei studies. It is found that the maximal pairing gap obtained is a few tenths of a MeV. The magnitude and the density region of the pairing gap are dependent on the $ΛΛ$ interaction and the treatment of neutron star matter. We calculate neutron star properties and find that whether the $^1S_0 $ superfluidity of $Λ$ hyperons exists in the core of neutron stars mainly depends on the $ΛΛ$ interaction used.

Emergent Halperin-Saslow mode and Gauge Glass in quantum Ising magnet TmMgGaO$_4$

description: We propose quenched disorders could bring novel quantum excitations and models to certain quantum magnets. Motivated by the recent experiments on the quantum Ising magnet TmMgGaO$_4$, we explore the effects of the quenched disorder and the interlayer coupling in this triangular lattice Ising antiferromagnet. It is pointed out that the weak quenched (non-magnetic) disorder would convert the emergent 2D Berezinskii-Kosterlitz-Thouless (BKT) phase and the critical region into a gauge glass. There will be an emergent Halperin-Saslow mode associated with this gauge glass. Using the Imry-Ma argument, we further explain the fate of the finite-field $C_3$ symmetry breaking transition at the low temperatures. The ferromagnetic interlayer coupling would suppress the BKT phase and generate a tiny ferromagnetism. With the quenched disorders, this interlayer coupling changes the 2D gauge glass into a 3D gauge glass, and the Halperin-Saslow mode persists. This work merely focuses on addressing a phase regime in terms of emergent U(1) gauge glass behaviors and hope to inspire future works and thoughts in weakly disordered frustrated magnets in general.

description: We classify all $q$-ary $Δ$-divisible linear codes which are spanned by codewords of weight $Δ$. The basic building blocks are the simplex codes, and for $q=2$ additionally the first order Reed-Muller codes and the parity check codes. This generalizes a result of Pless and Sloane, where the binary self-orthogonal codes spanned by codewords of weight $4$ have been classified, which is the case $q=2$ and $Δ=4$ of our classification. As an application, we give an alternative proof of a theorem of Liu on binary $Δ$-divisible codes of length $4Δ$ in the projective case.

description: We present a comprehensive statistical analysis of the properties of Type Ia SN light curves in the near infrared using recent data from PAIRITEL and the literature. We construct a hierarchical Bayesian framework, incorporating several uncertainties including photometric error, peculiar velocities, dust extinction and intrinsic variations, for coherent statistical inference. SN Ia light curve inferences are drawn from the global posterior probability of parameters describing both individual supernovae and the population conditioned on the entire SN Ia NIR dataset. The logical structure of the hierarchical model is represented by a directed acyclic graph. Fully Bayesian analysis of the model and data is enabled by an efficient MCMC algorithm exploiting the conditional structure using Gibbs sampling. We apply this framework to the JHK_s SN Ia light curve data. A new light curve model captures the observed J-band light curve shape variations. The intrinsic variances in peak absolute magnitudes are: sigma(M_J) = 0.17 +/- 0.03, sigma(M_H) = 0.11 +/- 0.03, and sigma(M_Ks) = 0.19 +/- 0.04. We describe the first quantitative evidence for correlations between the NIR absolute magnitudes and J-band light curve shapes, and demonstrate their utility for distance estimation. The average residual in the Hubble diagram for the training set SN at cz > 2000 km/s is 0.10 mag. The new application of bootstrap cross-validation to SN Ia light curve inference tests the sensitivity of the model fit to the finite sample and estimates the prediction error at 0.15 mag. These results demonstrate that SN Ia NIR light curves are as effective as optical light curves, and, because they are less vulnerable to dust absorption, they have great potential as precise and accurate cosmological distance indicators.

description: Distinguishing COVID-19 from other flu-like illnesses can be difficult due to ambiguous symptoms and still an initial experience of doctors. Whereas, it is crucial to filter out those sick patients who do not need to be tested for SARS-CoV-2 infection, especially in the event of the overwhelming increase in disease. As a part of the presented research, logistic regression and XGBoost classifiers, that allow for effective screening of patients for COVID-19, were generated. Each of the methods was tuned to achieve an assumed acceptable threshold of negative predictive values during classification. Additionally, an explanation of the obtained classification models was presented. The explanation enables the users to understand what was the basis of the decision made by the model. The obtained classification models provided the basis for the DECODE service (decode.polsl.pl), which can serve as support in screening patients with COVID-19 disease. Moreover, the data set constituting the basis for the analyses performed is made available to the research community. This data set consisting of more than 3,000 examples is based on questionnaires collected at a hospital in Poland.

description: We present a theory that efficiently describes the quantum dynamics of an electronic excitation that is coupled to a continuous, highly structured phonon environment. Based on a stochastic approach to non-Markovian open quantum systems, we develop a dynamical framework that allows us to handle realistic systems where a fully quantum treatment is desired yet the usual approximation schemes fail. The capability of the method is demonstrated by calculating spectra and energy transfer dynamics of mesoscopic molecular aggregates, elucidating the transition from fully coherent to incoherent transfer.

Pink Mouse

description: I have been deaf to operatic art for half my life, because I believed that opera was based on an artificial foundation of continuous singing, incompatible with living life. I have never fought against operas, I have never mocked them, like Mayakovsky, who believed that operas were made for non-smokers, in other words, for special lovers of this special dish, to which I, for my part, was simply indifferent.
But one day the opera came to my house, I had nowhere to retreat, the brilliant Schnittke created an opera based on my mini-novel “Life with an Idiot.” I not only admitted my mistake – I rushed to correct it, reworking my ideas about freedom in art. Now I think that opera is the freest direction of all the arts. What used to seem conventional to me has now become an amazing absoluteness. In opera, everything is allowed. It is an almost metaphysical dimension, close to enlightenment.
After Schnittke, the musicality of my prose became quite conscious, form-generating. In this respect, the novel “The Pink Mouse” became a rhythm novel, that is, a simultaneously thought-out and spontaneous musical phenomenon. Iraida Yusupova turned the musicality of the novel into music, verbal images into musical phrases. The novel went to the screen of her media opera, having lost nothing, on the contrary, having acquired stage authenticity.
The opera's heroes themselves received the right to musical existence thanks to the novel's proto-heroine, the Pink Mouse. She was in the novel and remained in Iraida's opera as a clot of vital energy in all its possible manifestations, from rational to divine, from aesthetic to erotic.
The Pink Mouse ignited existence.
Young Marusya Mendeleyeva, her colleague in the design of the plot of the narrative, is not far behind her. No less significant a figure in the opera is the Guitarist, the chief of evil will, who, however, is in love throughout the opera, and in this state does not fully understand who he is: an agent of love or world evil. In this internal battle with himself, the Guitarist is a new rich operatic figure who finds his theme in the song composition “The Last Lover” – an undoubted pinnacle of modern opera art.
None of the other heroes of the opera were created as accomplices of our favorites. Dad is a liberal, Mom is a lover of love, Klop, the first gentleman of Marusya Mendeleyeva, his dad, who is eaten as a cutlet many times in the opera – each sister has an earring.
Amazingly suits Iraida's music and the artistic design of the media opera. It is difficult to tear yourself away from the screen. The opera is long, like the battle of love relationships itself, like a full-fledged love act, continuing for hours without stopping.
This is a love masterpiece, I have no doubt that this is exactly so.

Utilizzando i dati del telescopio della NASA Fermi, un gruppo di scienziati del Fermi National Accelerator Laboratory (Fermilab) e dell'Università di Chicago avrebbero sviluppato nuove mappe che  mostrano una maggiore produzione di raggi gamma che sembra potersi giustificare con qualche forma di materia oscura. il commento di Patrizia Caraveo

description: In this work, we only use data on the unstable manifold to locate the partition boundaries by checking folding points at different levels, which practically coincide with homoclinic tangencies (HTs). The method is then applied to the classic two-dimensional Henon map and a well-known three-dimensional map. Comparison with previous results is made in the Henon case and Lyapunov exponents are computed through the metric entropy based on the partition, to show the validity of the current scheme.
title: A sequential Monte Carlo algorithm with transformations for Bayesian model exploration: applications in population genetics

description: Given a statistical model that attempts to explain the data, calculating the Bayes’ posterior distribution of the models parameters is desirable. The marginal likelihood of the model is also of interest, which is used for model comparison. However, for most applications, only estimates of these two measurements can be obtained with a class of methods that give consistent estimates being Monte Carlo algorithms. This thesis attempts to improve both the process in inferring a high-dimensional posterior distribution and the corresponding model marginal likelihood, on the condition that we can define an ordered set of statistical models in which deterministic transformations between each adjacent model can be applied. We propose an adaption of the sequential Monte Carlo algorithm, which we term the “transformation Sequential Monte Carlo” algorithm. The key feature of this algorithm is by defining a series of target distributions, that make use of said mentioned model transformations, we aim to infer high dimensional models by using easier to estimate posteriors from lower dimensional models with a model transformation applied. Our proposed algorithm has advantages over many established MC methods. One notable advantage is that we can tailor the algorithm if we wish to update a posterior distribution by including additional observations, but these observations also correspond to a new parameter set that needs to be inferred. Alternatively it is useful where the parameter space can become too large to explore using basic MC methods, for example if there exists an exponential or factorial relationship with observation size and the number of discrete values, but using a lower dimensional model and incorporating it into the model exploration assists with convergence. We test these strengths of tSMC under three applications, which include two population genetics applications being ancestral reconstruction under the coalescent and the other being the Structure algorithm.

description: We determine non-perturbatively the normalisation factor $r_\mathrm{m}\equiv Z_{\rm S}/Z_{\rm S}^{0}$, where $Z_{\rm S}$ and $Z_{\rm S}^{0}$ are the renormalisation parameters of the flavour non-singlet and singlet scalar densities, respectively. This quantity is required in the computation of quark masses with Wilson fermions and for instance the renormalisation of nucleon matrix elements of scalar densities. Our calculation involves simulations of finite-volume lattice QCD with the tree-level Symanzik-improved gauge action, $N_\mathrm{f} = 3$ mass-degenerate $\mathrm{O}(a)$ improved Wilson fermions and Schrödinger functional boundary conditions. The slope of the current quark mass, as a function of the subtracted Wilson quark mass is extracted both in a unitary setup (where nearly chiral valence and sea quark masses are degenerate) and in a non-unitary setup (where all valence flavours are chiral and the sea quark masses are small). These slopes are then combined with $Z \equiv Z_{\rm P}/(Z_{\rm S}Z_{\rm A})$ in order to obtain $r_\mathrm{m}$. A novel chiral Ward identity is employed for the calculation of the normalisation factor $Z$. Our results cover the range of gauge couplings corresponding to lattice spacings below $0.1\,$fm, for which $N_\mathrm{f} = 2+1$ QCD simulations in large volumes with the same lattice action are typically performed.
