description: Whenever a sensor is mounted on a robot hand it is important to know the relationship between the sensor and the hand. The problem of determining this relationship is referred to as hand-eye calibration, which is important in at least two types of tasks: (i) map sensor centered measurements into the robot workspace and (ii) allow the robot to precisely move the sensor. In the past some solutions were proposed in the particular case of a camera. With almost no exception, all existing solutions attempt to solve the homogeneous matrix equation AX=XB. First we show that there are two possible formulations of the hand-eye calibration problem. One formulation is the classical one that we just mentioned. A second formulation takes the form of the following homogeneous matrix equation: MY=M'YB. The advantage of the latter is that the extrinsic and intrinsic camera parameters need not be made explicit. Indeed, this formulation directly uses the 3 by 4 perspective matrices (M and M') associated with two positions of the camera. Moreover, this formulation together with the classical one cover a wider range of camera-based sensors to be calibrated with respect to the robot hand. Second, we develop a common mathematical framework to solve for the hand-eye calibration problem using either of the two formulations. We present two methods, (i) a rotation then translation and (ii) a non-linear solver for rotation and translation. Third, we perform a stability analysis both for our two methods and for the classical linear method of Tsai and Lenz (1989). In the light of this comparison, the non-linear optimization method, that solves for rotation and translation simultaneously, seems to be the most robust one with respect to noise and to measurement errors.

description: Natural protected areas are vital for biodiversity, climate change mitigation, and supporting ecological processes. Despite their significance, comprehensive mapping is hindered by a lack of understanding of their characteristics and a missing land cover class definition. This paper aims to advance the explanation of the designating patterns forming protected and wild areas. To this end, we propose a novel framework that uses activation maximization and a generative adversarial model. With this, we aim to generate satellite images that, in combination with domain knowledge, are capable of offering complete and valid explanations for the spatial and spectral patterns that define the natural authenticity of these regions. Our proposed framework produces more precise attribution maps pinpointing the designating patterns forming the natural authenticity of protected areas. Our approach fosters our understanding of the ecological integrity of the protected natural areas and may contribute to future monitoring and preservation efforts.

description: We study the effects of the allocation of distributed generation on the resilience of power grids. We find that an unconstrained allocation and growth of the distributed generation can drive a power grid beyond its design parameters. In order to overcome such a problem, we propose a topological algorithm derived from the field of Complex Networks to allocate distributed generation sources in an existing power grid.

Questions and prospects in quarkonium polarization measurements from proton-proton to nucleus-nucleus collisions

Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Polarization measurements are the best instrument to understand how quark and antiquark combine into the different quarkonium states, but no model has so far succeeded in explaining the measured J/psi and Upsilon polarizations. On the other hand, the experimental data in proton-antiproton and proton-nucleus collisions are inconsistent, incomplete and ambiguous. New analyses will have to properly address often underestimated issues: the existence of azimuthal anisotropies, the dependence on the reference frame, the influence of the experimental acceptance on the comparison with other measurements and with theory. Additionally, a recently developed frame-invariant formalism will provide an alternative and often more immediate physical viewpoint and, at the same time, will help probing systematic effects due to experimental biases. The role of feed-down decays from heavier states, a crucial missing piece in the current experimental knowledge, will have to be investigated. Ultimately, quarkonium polarization measurements will also offer new possibilities in the study of the properties of the quark-gluon plasma.

description: Colonies of bacteria grown on thin agar plate exhibit fractal patterns as a result of adaptation to their environments. The bacterial colony pattern formation is regulated crucially by chemotaxis, the movement of cells along a chemical concentration gradient. Here, the dynamics of pattern formation in bacterial colony is investigated theoretically through a continuum model that considers chemotaxis. In the case of the gradient sensed by the bacterium is nearly uniform, the bacterial colony patterns are self-similar, which they look the same at every scale. The scaling law of the bacterial colony growth has been revealed explicitly. Chemotaxis biases the movement of bacterial population in colony trend toward the chemical attractant. Moreover, the bacterial colonies evolve long time as the traveling wave with sharp front.

description: Catanese surfaces are regular surfaces of general type with $p_g=0$. They specialize to double covers of Barlow surfaces. We prove that the $CH_0$ group of a Catanese surface is equal to $\mathbb{Z}$, which implies the same result for the Barlow surfaces. We will also give a conditional application (more precisely, assuming the variational Hodge conjecture) of the same method to the Chow motive of low degree $K3$ surfaces.

description: A study on filtering aspects of airborne wind energy generators is presented. This class of renewable energy systems aims to convert the aerodynamic forces generated by tethered wings, flying in closed paths transverse to the wind flow, into electricity. The accurate reconstruction of the wing's position, velocity and heading is of fundamental importance for the automatic control of these kinds of systems. The difficulty of the estimation problem arises from the nonlinear dynamics, wide speed range, large accelerations and fast changes of direction that the wing experiences during operation. It is shown that the overall nonlinear system has a specific structure allowing its partitioning into sub-systems, hence leading to a series of simpler filtering problems. Different sensor setups are then considered, and the related sensor fusion algorithms are presented. The results of experimental tests carried out with a small-scale prototype and wings of different sizes are discussed. The designed filtering algorithms rely purely on kinematic laws, hence they are independent from features like wing area, aerodynamic efficiency, mass, etc. Therefore, the presented results are representative also of systems with larger size and different wing design, different number of tethers and/or rigid wings.

real-time quantitative polymerase chain reaction

description: Killer cell immunoglobulin-like receptors (KIRs), expressed on natural killer cells and T cells, have considerable biomedical relevance playing significant roles in immunity, pregnancy and transplantation. The $\textit{KIR }$ locus is one of the most complex and polymorphic regions of the human genome. Extensive sequence homology and copy number variation makes $\textit{KIR }$s technically laborious and expensive to type. To aid the investigation of $\textit{KIR }$s in human disease we developed a high-throughput, multiplex real-time polymerase chain reaction method to determine gene copy number for each $\textit{KIR }$ locus. We used reference DNA samples to validate the accuracy and a cohort of 1698 individuals to evaluate capability for precise copy number discrimination. The method provides improved information and identifies $\textit{KIR }$ haplotype alterations that were not previously visible using other approaches.

Study of the anomalous cross-section lineshape of e^+e^-\to D\bar D at ψ(3770) with an effective field theory

description: We study the anomalous cross-section lineshape of $e^+e^-\rightarrow D\bar D$ with an effective field theory. Near the threshold, most of the $D\bar D$ pairs are from the decay of $ψ(3770)$. Taking into account the fact that the nonresonance background is dominated by the $ψ(2S)$ transition, the produced $D\bar D$ pair can undergo final-state interactions before the pair is detected. We propose an effective field theory for the low-energy $D\bar D$ interactions to describe these final-state interactions and find that the anomalous lineshape of the $D\bar D$ cross section observed by the BESII collaboration can be well described.

description: Many countries have a rapidly ageing population, placing strain on health services and creating a growing market for assistive technology for older people. We have, through a student-led, 12-week project for 10 students from a variety of science and engineering backgrounds, developed an integrated sensor system to enable older people, or those at risk, to live independently in their own homes for longer, while providing reassurance for their family and carers. We provide details on the design procedure and performance of our sensor system and the management and execution of a short-term, student-led research project. Detailed information on the design and use of our devices, including a door sensor, power monitor, fall detector, general in-house sensor unit and easy-to-use location-aware communications device, is given, with our open designs being contrasted with closed proprietary systems. A case study is presented for the use of our devices in a real-world context, along with a comparison with commercially available systems. We discuss how the system could lead to improvements in the quality of life of older users and increase the effectiveness of their associated care network. We reflect on how recent developments in open source technology and rapid prototyping increase the scope and potential for the development of powerful sensor systems and, finally, conclude with a student perspective on this team effort and highlight learning outcomes, arguing that open technologies will revolutionize the way in which technology will be deployed in academic research in the future.

description: MnxGa films with high perpendicular anisotropy, coercivity and energy product have great application potential in ultrahigh-density perpendicular recording, permanent magnets, spin-transfer-torque memory and oscillators, magneto-resistance sensors and ferromagnetic metal/semiconductor heterostructure devices. Here we present a comprehensive diagram of effective magnetism-tailoring of perpendicularly magnetized MnxGa films grown on III-V semiconductor GaAs by using molecular-beam epitaxy for the first time, by systematically investigating the wide-range composition and detailed post-growth annealing effects. We show that the (001)-orientated MnxGa films with L10 or D022 ordering could be crystallized on GaAs in a very wide composition range from x=0.76 to 2.6. L10-ordered MnxGa films show robust magnetization, high remanent ratio, giant perpendicular anisotropy, high intrinsic and extrinsic coercivity, and large energy product, which make this kind of material favorable for perpendicular magnetic recording, high-performance spintronic devices and permanent magnet applications. In contrast, D022-ordered films exhibit lower perpendicular anisotropy and weaker magnetism. Post-growth annealing MnxGa films studies reveal high thermal-stability up to 450 oC, and effective tailoring of magnetic properties can be realized by prolonging annealing at 450 oC. These results would be helpful for understanding this kind of material and designing new spintronic devices for specific practical applications.

description: A redistribution of Cr atoms related to a phase decomposition (PD) caused by an isothermal annealing at 415 C in a 15.15 at%Cr Fe-Cr alloy was studied in an ex-situ way by the conversion electrons Mössbauer spectroscopy. Analysis of the spectra in terms of a two-shell model enabled determination of probabilities of 17 different atomic configurations and average numbers of Cr atoms within the first (1NN) and the second (2NN) neighbor shells versus annealing time, separately. The annealing-time evolution of these numbers, expressed in terms of the Cowley-Warren short-range order (SRO) parameters, was shown to follow the Johnson-Mehl-Avrami-Kolgomorov equation. The SRO-parameter averaged over the 1NN-2NN shells was revealed to be linearly correlated with the average hyperfine field. Signatures in favor of the nucleation and growth mechanisms responsible for PD are discussed, too.

description: Heterotopien sind räumliche Herausforderungen der gesellschaftlichen Ordnung. Sie speisen sich nicht allein aus realen räumlichen Gegebenheiten, sondern auch aus etablierten Zuschreibungen. Am Beispiel Venedig zeigt sich diese Verschränkung wie auch die Wirkmacht des Zusammenspiels von besonderer Raumordnung und tradierten Bildern. Die ästhetische Umsetzung des Stadtbildes in Rilkes Neuen Gedichten (Venezianischer Morgen (1908), Die Kurtisane (1907)) und in Madonnas Musikvideo Like a Virgin (1984) akzentuiert die Identifikation von Stadtraum und Frauenkörper und beweist einmal mehr die Bedeutung eines bewussten Umgangs mit Foucaults Heterotopiekonzept.

description: We construct supersymmetric Q-balls and boson stars in (d+1) dimensions. These non-topological solitons are solutions of a scalar field model with global U(1) symmetry and a scalar field potential that appears in gauge-mediated supersymmetry (SUSY) breaking in the minimal supersymmetric extension of the Standard Model (MSSM). We are interested in both the asymptotically flat as well as in the asymptotically Anti-de Sitter (AdS) solutions. In particular, we show that for our choice of the potential gravitating, asymptotically flat boson stars exist in (2+1) dimensions. We observe that the behaviour of the mass and charge of the asymptotically flat solutions at the approach of the maximal frequency depends strongly on the number of spatial dimensions. For the asymptotically AdS solutions, the model on the conformal boundary can be interpreted as describing d-dimensional condensates of scalar glueballs.

The attempt to follow the way of establishing a link between the Romanian and the Italian cultural space, using as a vehicle the series of the Bibliography of Relations between Romanian literature and Foreign Literatures in the News Media is proposed not only as a simple statistic of literary facts reflected in newspapers and magazines, but also as a beginning for new potential research. In this particular case, which we have only tried to describe and construct a potential scheme, we could say that the pretext bears and develops in an apparently arid environment, from a collection that can be considered a priori of no interest. Instead, not only pages of literary history and culture – both Italian and Romanian – are opened, but also many other doors behind which hides the potential of the dynamic act of scientific literary research.

description: Background: Developmental pathways must be responsive to the environment. Phosphorylation of eIF2α enables a family of stress sensing kinases to trigger the integrated stress response (ISR), which has pro-survival and developmental consequences. Bone Morphogenetic Proteins (BMPs) regulate multiple developmental processes in organisms from insects to mammals. Results: Here we show in Drosophila that GCN2 antagonises BMP signaling through direct effects on translation and indirectly via the transcription factor crc (dATF4). Expression of a constitutively active GCN2 or loss of the eIF2α phosphatase dPPP1R15 impair developmental BMP signaling in flies. In cells, inhibition of translation by GCN2 blocks downstream BMP signaling. Moreover, loss of d4E-BP, a target of crc, augments BMP signaling in vitro and rescues tissue development in vivo. Conclusion: These results identify a novel mechanism by which the ISR modulates BMP signaling during development.

Eine Möglichkeit, queere Räume zu erkunden, wird in nachfolgendem Bildessay über Bildassoziationen versucht. Die Bilderserie spiegelt die Schwierigkeiten wider zu definieren, was ein queerer Raum ist und was ihn ausmacht. Die vorgeschlagenen Antworten auf die Frage sind so unterschiedlich wie die Akteur_innen, die sie formulieren, und die politischen und theoretischen Perspektiven, aus denen sie sprechen. Ich möchte mit diesem Essay zum Nachdenken und Diskutieren anregen. Es enthält einige Versuche, queere Räume einzukreisen, reflektiert Zwischenergebnisse, die ich zum Teil wieder verworfen habe, und viele offene Fragen. Bilder bieten sich dazu an, den Raum für Assoziationen zu öffnen, und ermöglichen neue Zugänge. Zugleich ist die Auswahl der Bilder beschränkt (und subjektiv); dadurch wird der Blick in eine ganz bestimmte Richtung gelenkt. So ist dies ein künstlerischer und persönlicher, nur hintergründig wissenschaftlicher Versuch, sich dem Thema zu nähern.

description: We consider nonlinear recurrences generated from cluster mutations applied to quivers that have the property of being cluster mutation-periodic with period 1. Such quivers were completely classified by Fordy and Marsh, who characterised them in terms of the skew-symmetric matrix that defines the quiver. The associated nonlinear recurrences are equivalent to birational maps, and we explain how these maps can be endowed with an invariant Poisson bracket and/or presymplectic structure. Upon applying the algebraic entropy test, we are led to a series of conjectures which imply that the entropy of the cluster maps can be determined from their tropical analogues, which leads to a sharp classification result. Only four special families of these maps should have zero entropy. These families are examined in detail, with many explicit examples given, and we show how they lead to discrete dynamics that is integrable in the Liouville-Arnold sense.

Abstract Prolonged-release (PR; as ascribed in the EU) or extended-release (as ascribed in the USA) bupivacaine/meloxicam (HTX-011; hereafter referred to as bupivacaine/meloxicam PR; Zynrelef®) is a synergistic fixed-dose combination (FDC) of the local anaesthetic bupivacaine and the NSAID meloxicam. It is approved in the EU and the USA to treat postoperative pain. After needle-free application at the surgical site, the novel polymer technology allows simultaneous diffusion of bupivacaine and meloxicam over 72 h. In clinical trials, bupivacaine/meloxicam PR significantly reduced postoperative pain and opioid consumption relative to bupivacaine hydrochloride (HCl) and placebo in patients undergoing bunionectomy, herniorrhaphy or total knee arthroplasty (TKA). When used as the foundation of a scheduled non-opioid multimodal analgesia (MMA) regimen, bupivacaine/meloxicam PR further improved pain control and reduced the need for opioids following surgery. Bupivacaine/meloxicam PR was generally well tolerated, with a lower incidence of opioid-related adverse events than bupivacaine HCl and placebo. Although additional data would be beneficial, current evidence indicates that bupivacaine/meloxicam PR is a promising non-opioid treatment option for the management of postoperative pain. © Springer Nature Switzerland AG 2021

description: In a recent paper in this journal [J. Stat. Mech. (2009) P02037] we proposed a new, physically motivated, distribution function for modeling individual incomes having its roots in the framework of the k-generalized statistical mechanics. The performance of the k-generalized distribution was checked against real data on personal income for the United States in 2003. In this paper we extend our previous model so as to be able to account for the distribution of wealth. Probabilistic functions and inequality measures of this generalized model for wealth distribution are obtained in closed form. In order to check the validity of the proposed model, we analyze the U.S. household wealth distributions from 1984 to 2009 and conclude an excellent agreement with the data that is superior to any other model already known in the literature.

description: Basic Harish-Chandra series are asymptotically free meromorphic solutions of the system of basic hypergeometric difference equations associated to root systems. The associated connection coefficients are explicitly computed in terms of Jacobi theta functions. We interpret the connection coefficients as the transition functions for asymptotically free meromorphic solutions of Cherednik's root system analogs of the quantum Knizhnik-Zamolodchikov equations. They thus give rise to explicit elliptic solutions of root system analogs of dynamical Yang-Baxter and reflection equations. Applications to quantum c-functions, basic hypergeometric functions, reflectionless difference operators and multivariable Baker-Akhiezer functions are discussed.

description: Low Mach number, high beta fast mode shocks can occur in the magnetic reconnection outflows of solar flares. These shocks, which occur above flare loop tops, may provide the electron energization responsible for some of the observed hard X-rays and contemporaneous radio emission. Here we present new 2D particle-in-cell simulations of low Mach number/high beta quasi-perpendicular shocks. The simulations show that electrons above a certain energy threshold experience shock-drift-acceleration. The transition energy between the thermal and non-thermal spectrum and the spectral index from the simulations are consistent with some of the X-ray spectra from RHESSI in the energy regime of $E\lesssim 40\sim 100$ keV. Plasma instabilities associated with the shock structure such as the modified-two-stream and the electron whistler instabilities are identified using numerical solutions of the kinetic dispersion relations. We also show that the results from PIC simulations with reduced ion/electron mass ratio can be scaled to those with the realistic mass ratio.

description: We perform an analytic and numerical study of parametric resonance in a three-neutrino framework for sub-GeV neutrinos which travel through a periodic density profile. Commensurate with the initial level of approximation, we develop a parametric resonance condition similar to the exact condition for two-neutrino systems. For a castle wall density profile, the ν_e to ν_μoscillation probability is enhanced significantly and bounded by cos^2 θ_{23}. The CP phase δenters into the oscillation probability as a phase shift. For several cases, we examine the interplay between the characteristics of the castle wall profile and the CP phase and determine which profiles maximize the separation between oscillations with δ= 0, π/2, π. We also consider neutrinos which travel along a chord through the earth, passing from the mantle to core and back to mantle again. Significant enhancement of the oscillation probability is seen even in the case in which the neutrino energy is far from the MSW resonant energies. At 500 GeV, the difference between oscillation probabilities with δ=0 and δ=π/2 is maximized.

description: The experimental situation of Dark Matter Direct Detection has reached an exciting cross-roads, with potential hints of a discovery of Dark Matter (DM) from the CDMS, CoGeNT, CRESST-II and DAMA experiments in tension with null-results from xenon-based experiments such as XENON100 and LUX. Given the present controversial experimental status, it is important that the analytical method used to search for DM in Direct Detection experiments is both robust and flexible enough to deal with data for which the distinction between signal and background points is difficult, and hence where the choice between setting a limit or defining a discovery region is debatable. In this article we propose a novel (Bayesian) analytical method, which can be applied to all Direct Detection experiments and which extracts the maximum amount of information from the data. We apply our method to the XENON100 experiment data as a worked example, and show that firstly our exclusion limit at 90% confidence is in agreement with their own for the 225 Live Days data, but is several times stronger for the 100 Live Days data. Secondly we find that, due to the two points at low values of S1 and S2 in the 225 days data-set, our analysis points to either weak consistency with low-mass Dark Matter or the possible presence of an unknown background. Given the null-result from LUX, the latter scenario seems the more plausible.

description: This music recommendation system that utilizes facial expressions to determine the user's mood and preferences. The device is made to function both with and without a face mask, making it useful and adaptable in the pandemic situation of today .Although prior studies have looked at music suggestion and facial emotion identification separately, the particular setting of face masks poses a special problem as well previous research did not focus on the accuracy of the models and they did not used multiple emotions[3]. This issues necessitates research into how emotions are perceived and expressed when a mask is partially covering the face through outward facial features like the eyes and brows[7]. In order to accurately recognize facial emotions and offer music, a revolutionary strategy combining cutting-edge methods, specialized convolutional neural network (CNN) layers, and modified activation keys must be developed. Face masks offer a challenge, thus the solution uses cutting-edge methods to evaluate the remaining exposed facial features, like the eyes and brows, in order to efficiently capture emotional information[5]. The researcher suggests modifying current CNN designs to do this by adding specialized layers that concentrate solely on the visible facial regions[11]. The solution tries to improve the network's capacity to derive meaningful emotional information from the observable face features by customizing the network's design, for as by including attention mechanisms or feature fusion modules.The researcher also investigates the usage of unique activation keys that direct the network's focus on pertinent face regions and emotional cues while ignoring masked regions. The technique seeks to enhance the accuracy and robustness of facial emotion recognition by providing customized activation keys that emphasize the visible facial areas and suppress the impact of face masks.

The translation invariant massive Nelson model: III. Asymptotic completeness below the two-boson threshold

description: We show asymptotic completeness of two-body scattering for a class of translation invariant models describing a single quantum particle (the electron) linearly coupled to a massive scalar field (bosons). Our proof is based on a recently established Mourre estimate for these models. In contrast to previous approaches, it requires no number cutoff, no restriction on the particle-field coupling strength, and no restriction on the magnitude of total momentum. Energy, however, is restricted by the two-boson threshold, admitting only scattering of a dressed electron and a single asymptotic boson. The class of models we consider include the UV-cutoff Nelson and polaron models.

description: Pleomorphic xanthoastrocytoma (PXA) poses a diagnostic challenge. The present study relies on methylation-based predictions and focuses on copy number variations (CNV) in PXA. We identified 551 tumors from patients having received the histologic diagnosis or differential diagnosis pleomorphic xanthoastrocytoma (PXA) uploaded to the web page www.molecularneuropathology.org. Of these 551 tumors, 165 received the prediction “methylation class (anaplastic) pleomorphic xanthoastrocytoma” with a calibrated score >=0.9 by the brain tumor classifier version v12.8 and, therefore, were defined the PXA reference set designated mcPXAref. In addition to these 165 mcPXAref, 767 other tumors received the prediction mcPXA with a calibrated score >=0.9 but without a histological PXA diagnosis. The total number of individual tumors predicted by histology and/or by methylome based classification as PXA, mcPXA or both was 1318, and these were designated the study cohort. The selection of a control cohort was guided by methylation-based predictions recurrently observed for the other 386/551 tumors diagnosed as histologic PXA. 131/386 received predictions for another entity besides PXA with a score >=0.9. Control tumors corresponding to the 11 most common other predictions were selected, adding up to 1100 reference cases. CNV profiles were calculated from all methylation datasets of the study and control cohorts. Special attention was given to the 7/10 signature, gene amplifications and homozygous deletion of CDKN2A/B. Comparison of CNV in the subsets of the study cohort and the control cohort were used to establish relations independent of histological diagnoses. Tumors in mcPXA were highly homogenous in regard to CNV alterations, irrespective of the histological diagnoses. The 7/10 signature commonly present in glioblastoma, IDH-wildtype, was present in 15-20% of mcPXA, whereas amplification of oncogenes (likewise common in glioblastoma) was very rare in mcPXA (<1%). In contrast, the histology-based PXA group exhibited high variance in regard to methylation classes as well as to CNVs. Our data add to the notion, that histologically defined PXA likely only represent a subset of the biological disease.
