description: A mostly right-handed sneutrino as the lightest supersymmetric particle (LSP) is an interesting dark matter candidate, leading to LHC signatures which can be quite distinct from those of the conventional neutralino LSP. Using SModelSv1.0.1 for testing the model against the limits published by ATLAS and CMS in the context of so-called Simplified Model Spectra (SMS), we investigate to what extent the supersymmetry searches at Run 1 of the LHC constrain the sneutrino-LSP scenario. Moreover, we discuss the most relevant topologies for which no SMS results are provided by the experimental collaborations but which would allow to put more stringent constraints on sneutrino LSPs. These include, for instance, the mono-lepton signature which should be particularly interesting to consider at Run 2 of the LHC.

description: Lenses are an important tool in applied category theory. While individual lenses have been widely used in applications, many of the mathematical properties of the corresponding categories of lenses have remained unknown. In this paper, we study the category of small categories and asymmetric delta lenses, and prove that it has several good exactness properties. These properties include the existence of certain limits and colimits, as well as so-called imported limits, such as imported products and imported pullbacks, which have arisen previously in applications. The category is also shown to be extensive, and it has an image factorisation system.

description: El metateatro considerado como una estrategia textual que promueve la vulneración de los límites entre la realidad y la ficción y, por tanto, el acercamiento entre el escenario y la sala, es utilizado, en ocasiones, por los personajes teatrales para destruir su propia naturaleza ficcional destinada al olvido, a la desaparición, en cuanto termine la función teatral. Estos personajes pasan, así, a considerarse metaficcionales, dado que son conscientes de su naturaleza efímera y luchan por mantener esa huella en la masa espectadora. De este modo, a partir de textos teatrales de Sanchis Sinisterra, Juan Mayorga, Antonia Bueno, Antonio Martínez Ballesteros, Paloma Pedrero y Carmen Resino, analizo esos recursos metateatrales de los que echan mano estos personajes para evitar caer en el olvido.

description: Tracelets are the intrinsic carriers of causal information in categorical rewriting systems. In this work, we assemble tracelets into a symmetric monoidal decomposition space, inducing a cocommutative Hopf algebra of tracelets. This Hopf algebra captures important combinatorial and algebraic aspects of rewriting theory, and is motivated by applications of its representation theory to stochastic rewriting systems such as chemical reaction networks.

description: Air quality and climate change are among the biggest societal challenges that we face today.
 Atmospheric free radicals, particularly hydroxyl (•OH) and nitrate (•NO3), are the drivers of chemical processes that determine atmospheric composition and thus influence local and global air quality and climate. Detecting and understanding the behavior of radical species in the atmosphere is therefore of paramount importance and hence a major research goal in atmospheric science. Current techniques for measuring radicals are based on spectroscopic and mass spectrometric methods, which although sensitive and robust, are technically complex, cumbersome, and expensive. The central aim of this project is to develop organic surfaces on confined 1D interfaces to fabricate radical sensors on a Silicon junctionless nanowire transistor (Si JNT) platform. Silicon junctionless nanowire transistors (JNTs) have recently detected record low concentrations (down to the zeptomolar range) of the protein streptavidin in liquid phase. However, JNTs have not yet been tested for sensing in gas phase. Additional Information:  Sayantan Ghosh delivered this presentation for RSC Twitter Conference.

title:  L’oblio del censore. Censurato dalla critica

Publisher: name: Roma TrE-Press

description: Alla luce degli studi di Tzvetan Todorov, Paul Ricoeur, Umberto Eco e Harald Weinrich sul rapporto tra oblio e memoria, il presente articolo intende esplorare il tema dell’oblio attraverso l’analisi del controverso e incompreso film argentino El censor (Calcagno, 1995). In un’epoca in cui la cultura è fortemente rivolta al recupero della memoria e alla denuncia di ogni forma di repressione esercitata durante l’ultima dittatura, il regista e lo sceneggiatore riportano alla luce il tema della censura attraverso un personaggio contraddittorio – che impone agli altri quell’oblio di cui soffre – e che non esclude l’immedesimazione dello spettatore. Dalla disamina delle recensioni apparse all’uscita del film sui maggiori giornali e riviste argentini (unica bibliografia esistente sul film), emerge una visione condivisa e precostituita sul concetto di oblio, che poco si attaglia al protagonista e, soprattutto, non tiene conto della complementarietà e dell’interazione tra l’oblio e la memoria.

description: The vibration behaviour of turbocharger rotors is influenced by the acting loads as well as by the type and arrangement of the hydrodynamic bearings and their operating condition. Due to the highly non-linear bearing behaviour, lubricant film-induced excitations can occur, which lead to sub-synchronous rotor vibrations. A significant impact on the oscillation behaviour is attributed to the pressure distribution in the hydrodynamic bearings, which is influenced by the thermohydrodynamic conditions and the occurrence of outgassing processes. This contribution investigates the vibration behaviour of a floating ring supported turbocharger rotor. For detailed modelling of the bearings, the Reynolds equation with mass-conserving cavitation, the three-dimensional energy equation and the heat conduction equation are solved. To examine the impact of outgassing processes and thrust bearing on the occurrence of sub-synchronous rotor vibrations separately, a variation of the bearing model is made. This includes run-up simulations considering or neglecting thrust bearings and two-phase flow in the lubrication gap. It is shown that, for a reliable prediction of sub-synchronous vibrations, both the modelling of outgassing processes in hydrodynamic bearings and the consideration of thrust bearing are necessary.

description: Symplectic vector spaces are the phase spaces of linear mechanical systems. The symplectic form describes, for example, the relation between position and momentum as well as current and voltage. The category of linear Lagrangian relations between symplectic vector spaces is a symmetric monoidal subcategory of relations which gives a semantics for the evolution -- and more generally linear constraints on the evolution -- of various physical systems. We give a new presentation of the category of Lagrangian relations over an arbitrary field as a `doubled' category of linear relations. More precisely, we show that it arises as a variation of Selinger's CPM construction applied to linear relations, where the covariant orthogonal complement functor plays the role of conjugation. Furthermore, for linear relations over prime fields, this corresponds exactly to the CPM construction for a suitable choice of dagger. We can furthermore extend this construction by a single affine shift operator to obtain a category of affine Lagrangian relations. Using this new presentation, we prove the equivalence of the prop of affine Lagrangian relations with the prop of qudit stabilizer theory in odd prime dimensions. We hence obtain a unified graphical language for several disparate process theories, including electrical circuits, Spekkens' toy theory, and odd-prime-dimensional stabilizer quantum circuits.

description: We propose a categorical framework for processes which interact bidirectionally with both an environment and a 'controller'. Examples include open learners, in which the controller is an optimiser such as gradient descent, and an approach to compositional game theory closely related to open games, in which the controller is a composite of game-theoretic agents. We believe that 'cybernetic' is an appropriate name for the processes that can be described in this framework.

The cross-over scale approaches zero with increasing $N$ and the cross-over becomes a first order transition as $N\to\infty$ and $l\to 0$ with the limiting value of $2Pl/(N-1)t$ depending on the fixed value of $Nl$.

Entropy power inequalities for qudits

description: Shannon's entropy power inequality (EPI) can be viewed as a statement of concavity of an entropic function of a continuous random variable under a scaled addition rule: $$f(\sqrt{a}\,X + \sqrt{1-a}\,Y) \ge a f(X) + (1-a) f(Y) \quad \forall \, a \in [0,1].$$ Here, $X$ and $Y$ are continuous random variables and the function $f$ is either the differential entropy or the entropy power. König and Smith [arXiv:1205.3409] and De Palma, Mari, and Giovannetti [arXiv:1402.0404] obtained quantum analogues of these inequalities for continuous-variable quantum systems, where $X$ and $Y$ are replaced by bosonic fields and the addition rule is the action of a beamsplitter with transmissivity $a$ on those fields. In this paper, we similarly establish a class of EPI analogues for $d$-level quantum systems (i.e. qudits). The underlying addition rule for which these inequalities hold is given by a quantum channel that depends on the parameter $a \in [0,1]$ and acts like a finite-dimensional analogue of a beamsplitter with transmissivity $a$, converting a two-qudit product state into a single qudit state. We refer to this channel as a partial swap channel because of the particular way its output interpolates between the states of the two qudits in the input as $a$ is changed from zero to one. We obtain analogues of Shannon's EPI, not only for the von Neumann entropy and the entropy power for the output of such channels, but for a much larger class of functions as well. This class includes the Rényi entropies and the subentropy. We also prove a qudit analogue of the entropy photon number inequality (EPnI). Finally, for the subclass of partial swap channels for which one of the qudit states in the input is fixed, our EPIs and EPnI yield lower bounds on the minimum output entropy and upper bounds on the Holevo capacity.

description: We study the impact of using fluid-structure interactions (FSI) to simulate blood flow in a stenosed artery. We compare typical flow configurations using Navier–Stokes in a rigid geometry setting to a fully coupled FSI model. The relevance of vascular elasticity is investigated with respect to several questions of clinical importance. Namely, we study the effect of using FSI on the wall shear stress distribution, on the Fractional Flow Reserve and on the damping effect of a stenosis on the pressure amplitude during the pulsatile cycle. The coupled problem is described in a monolithic variational formulation based on Arbitrary Lagrangian Eulerian (ALE) coordinates. For comparison, we perform pure Navier–Stokes simulations on a pre-stressed geometry to give a good matching of both configurations. A series of numerical simulations that cover important hemodynamical factors are presented and discussed.

description: In this article, we present a numerical study of the optical properties of a metal nanowire interacting with a localized cavity in a two dimensional photonic crystal. The nature of the modes, their wavelength and width are investigated as a function of the particle radius. It is shown in particular that a particle with diameter about the lattice constant presents very narrow resonances corresponding to hybrid photonic-plasmonic modes, where increased lifetime is attributed to the decrease of the radiative losses by interaction with the photonic crystal. These results open interesting applications in areas where narrow plasmonic resonances are required, as in LSP-resonance based biosensing.

description: Abstract :  Silicon nanowire (Si NW) sensors are very promising because of their fast, low-cost, label-free, real-time detection of chemical and biological species. They have already demonstrated outstanding sensitivity and selectivity towards a large number of analytes in both liquid and gas phases. In particular, silicon junctionless nanowire transistors (JNTs) have recently detected record low concentrations (down to the zeptomolar range) of the protein streptavidin in liquid phase. However, JNTs have not yet been tested for sensing in gas phase. Here we present the fabrication and initial electrical characterisation of JNT-based sensors for detection of atmospheric free radicals such as hydroxyl (•OH) and nitrate (•NO3), which are the main drivers of chemical processes in the atmosphere. Silicon-on-insulator wafers have been used for device fabrication. The wafers have first been doped by a chain phosphorous implantation with nine different energies to form a box-like dopant profile across the 20 nm thick top Si layer. Subsequently, flash lamp annealing has been performed for defect healing and dopant activation. Device patterning has been based mainly on electron beam lithography, inductively-coupled reactive ion etching, metal deposition and lift-off processes. Initial electrical characterisation of fabricated devices by back-gating has proven their good performance and potential suitability for detection of atmospheric free radicals.

description: We investigate the collective dynamics of self-propelled particles able to probe and anticipate the orientation of their neighbors. We show that a simple anticipation strategy hinders the emergence of homogeneous flocking patterns. Yet, anticipation promotes two other forms of self-organization: collective spinning and swarming. In the spinning phase, all particles follow synchronous circular orbits, while in the swarming phase, the population condensates into a single compact swarm that cruises coherently without requiring any cohesive interactions. We quantitatively characterize and rationalize these phases of polar active matter and discuss potential applications to the design of swarming robots.

description: We show open games cover extensive form games with both perfect and imperfect information. Doing so forces us to address two current weaknesses in open games: the lack of a notion of player and their agency within open games, and the lack of choice operators. Using the former we construct the latter, and these choice operators subsume previous proposed operators for open games, thereby making progress towards a core, canonical and ergonomic calculus of game operators. Collectively these innovations increase the level of compositionality of open games, and demonstrate their expressiveness.

description: Berberine has been shown to have therapeutic advantages in the management of different diseases. Due to its actions and therapeutic applications, in compliance with “The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use”. (ICH) recommendations; a quick, precise and specific HPLC method was developed and validated. The chromatographic separation was carried out with Column C18 (4.6 mm X 250 mm), (5 microns) using 0.1% orthophosphoric acid: acetonitrile (60:40) as mobile phase, with a flow rate of 1 ml/min and at a wavelength of 349 nm. The developed method was also used for the estimation of berberine in various commercial preparations and also with formulated berberine-loaded cubosomal nano formulation according to ICH guidelines. Furthermore, forced degradation studies of berberine were investigated. The novel analytical technique was identified to be linear over the concentration ranging from 2 μg/ml to 14 μg/ml with R2 > 0.997. The method developed was accurate (with % recovery of 98.24% to 99.31%), precise (%RSD < 2.0%), and robust. The limit of quantification and limit of detection for berberine was found to be 0.064 μg/ml and 0.021 μg/ml respectively. In the presence of degradation products, the drug peak was obtained. The peaks for berberine were detected in the marketed formulations containing berberine and hence, the developed method could be applied to the estimation of berberine in berberine-containing formulations.

description: String diagrams are an increasingly popular algebraic language for the analysis of graphical models of computations across different research fields. Whereas string diagrams have been thoroughly studied as semantic structures, much less attention has been given to their algorithmic properties, and efficient implementations of diagrammatic reasoning are almost an unexplored subject. This work intends to be a contribution in such a direction. We introduce a data structure representing string diagrams in terms of adjacency matrices. This encoding has the key advantage of providing simple and efficient algorithms for composition and tensor product of diagrams. We demonstrate its effectiveness by showing that the complexity of the two operations is linear in the size of string diagrams. Also, as our approach is based on basic linear algebraic operations, we can take advantage of heavily optimised implementations, which we use to measure performances of string diagrammatic operations via several benchmarks.

description: A robust as well as precise technique aimed at determining the concentration of Cariprazine in bulk drugs along with formulations using RP-HPLC has been developed. The robustness study was optimized using Box Behnken statistical design. Separation was achieved using an Agilent 1260 Infinity II HPLC with an Agilent Zorbax Bonus RP column, as well as the mobile phase contained of methanol and 0.1% trifluoroacetic acid buffer (52.5:47.5) at a flow rate of 1 ml/min. The wavelength was set at 248 nm, and the method had an overall running period of 8 minutes, with the Cariprazine peak retention time at 3.83 min. The method exhibited linearity and accuracy for concentrations ranging from 80 to 120 μg/ml, with an R2 of 0.999 and accuracy RSD of 0.2%, 0.13%, and 0.05% for 80%, 100%, and 120%, respectively. Stress stability testing under basic conditions revealed 53.32% degradation. The technique’s limit of detection (LOD) and limit of quantification (LOQ) were very low, at 44.80 ng/ml and 135.60 ng/ml, correspondingly. These findings suggest that this method may be helpful during regular quality control evaluation of Cariprazine Hydrochloride in a variety of pharmaceutical formulations.

description: We report on the observation of half-quantum vortices (HQVs) in the easy-plane polar phase of an antiferromagnetic spinor Bose-Einstein condensate. Using in situ magnetization-sensitive imaging, we observe that pairs of HQVs with opposite core magnetization are generated when singly charged quantum vortices are injected into the condensate. The dynamics of HQV pair formation is characterized by measuring the temporal evolutions of the pair separation distance and the core magnetization, which reveals the short-range nature of the repulsive interactions between the HQVs. We find that spin fluctuations arising from thermal population of axial magnon excitations do not significantly affect the HQV pair formation dynamics. Our results demonstrate the instability of a singly charged vortex in the antiferromagnetic spinor condensate.

description: Dynamical systems are ubiquitous in science and engineering as models of phenomena that evolve over time. Although complex dynamical systems tend to have important modular structure, conventional modeling approaches suppress this structure. Building on recent work in applied category theory, we show how deterministic dynamical systems, discrete and continuous, can be composed in a hierarchical style. In mathematical terms, we reformulate some existing operads of wiring diagrams and introduce new ones, using the general formalism of C-sets (copresheaves). We then establish dynamical systems as algebras of these operads. In a computational vein, we show that Euler's method is functorial for undirected systems, extending a previous result for directed systems. All of the ideas in this paper are implemented as practical software using Catlab and the AlgebraicJulia ecosystem, written in the Julia programming language for scientific computing.

description: The gamma model is a generalized linear model for gamma-distributed outcomes. The model is widely applied in psychology, ecology or medicine. Recently, Gaffke et al. (J Stat Plan Inference 203:199–214, 2019) established a complete class and an essentially complete class of designs for gamma models to obtain locally optimal designs in particular when the linear predictor includes an intercept term. In this paper we extend this approach to gamma models having linear predictors without intercept. For a specific scenario sets of locally D- and A-optimal designs are established. It turns out that the optimality problem can be transformed to one under gamma models with intercept leading to a reduction in the dimension of the experimental region. On that basis optimality results can be transferred from one model to the other and vice versa. Additionally by means of the general equivalence theorem optimality can be characterized formultiple regression by a system of polynomial inequalitieswhich can be solved analytically or by computer algebra. Thus necessary and sufficient conditions can be obtained on the parameter values for the local D-optimality of specific designs. The robustness of the derived designs with respect to misspecification of the initial parameter values is examined by means of their local D-efficiencies.

description: Isogeometric analysis (IgA) uses the same class of basis functions for both, representing the geometry of the computational domain and approximating the solution. In practical applications, geometrical patches are used in order to get flexibility in the geometrical representation. This multi-patch representation corresponds to a decomposition of the computational domain into non-overlapping subdomains also called patches in the geometrical framework. We will present discontinuous Galerkin (dG) methods that allow for discontinuities across the subdomain (patch) boundaries. The required interface conditions are weakly imposed by the dG terms associated with the boundary of the sub-domains. The construction and the corresponding discretization error analysis of such dG multi-patch IgA schemes will be given for heterogeneous diffusion model problems in volumetric 2d and 3d domains as well as on open and closed surfaces. The theoretical results are confirmed by numerous numerical experiments which have been performed in G+SMO. The concept and the main features of the IgA library G+SMO are also described.

description: Design-by-Analogy (DbA) is a design methodology wherein new solutions, opportunities or designs are generated in a target domain based on inspiration drawn from a source domain; it can benefit designers in mitigating design fixation and improving design ideation outcomes. Recently, the increasingly available design databases and rapidly advancing data science and artificial intelligence technologies have presented new opportunities for developing data-driven methods and tools for DbA support. In this study, we survey existing data-driven DbA studies and categorize individual studies according to the data, methods, and applications in four categories, namely, analogy encoding, retrieval, mapping, and evaluation. Based on both nuanced organic review and structured analysis, this paper elucidates the state of the art of data-driven DbA research to date and benchmarks it with the frontier of data science and AI research to identify promising research opportunities and directions for the field. Finally, we propose a future conceptual data-driven DbA system that integrates all propositions.

description: Berberine has been shown to have therapeutic advantages in the management of different diseases. Due to its actions and therapeutic applications, in compliance with “The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use”. (ICH) recommendations; a quick, precise and specific HPLC method was developed and validated. The chromatographic separation was carried out with Column C18 (4.6 mm X 250 mm), (5 microns) using 0.1% orthophosphoric acid: acetonitrile (60:40) as mobile phase, with a flow rate of 1 ml/min and at a wavelength of 349 nm. The developed method was also used for the estimation of berberine in various commercial preparations and also with formulated berberine-loaded cubosomal nano formulation according to ICH guidelines. Furthermore, forced degradation studies of berberine were investigated. The novel analytical technique was identified to be linear over the concentration ranging from 2 μg/ml to 14 μg/ml with R2 > 0.997. The method developed was accurate (with % recovery of 98.24% to 99.31%), precise (%RSD < 2.0%), and robust. The limit of quantification and limit of detection for berberine was found to be 0.064 μg/ml and 0.021 μg/ml respectively. In the presence of degradation products, the drug peak was obtained. The peaks for berberine were detected in the marketed formulations containing berberine and hence, the developed method could be applied to the estimation of berberine in berberine-containing formulations.

description: The search for topological superconductors which support Majorana fermion excitations has been an important topic in condensed matter physics. In this work, we propose a new experimental scheme for engineering topological superconductors. In this scheme, by manipulating the superlattice structure of organic molecules placed on top of a superconductor with Rashba spin-orbit coupling, topological superconducting phases can be achieved without fine-tuning the chemical potential. Moreover, superconductors with different Chern numbers can be obtained by changing the superlattice structure of the organic molecules.

description: Here we are reporting a new bioactive flavanone glycoside. The compound having molecular formula C21H22O11, melting point 123-125°C, and ESI-MS m/z 451 was isolated from the methanolic extract of Tradescantia Spathacea Sw. Its characterization and structure elucidation was done with the help of various chemical degradation, color reactions, and spectral data like UV-Visible, FT-IR, electrospray ionization mass spectrometry technique, nuclear magnetic resonance spectroscopy, etc. It was recognized as 5,7,3’4’-tetrahydroxy flavanone 3’-O-D-mannopyranoside. This study was also designed to examine the efficacy of an isolated compound against various bacteria which are responsible for food spoilage and pathogens in humans. The organic flavanone glycoside of methanolic extract exhibited a promising antibacterial activity towards Escherichia coli (gram negative) MTCC 724, Bacillus subtilis MTCC 441, Staphylococcus aureus MTCC 737, Pseudomonas aerugenosa MTCC 424, and Salmonella typhimurium MTCC 3224. A new flavanone glycoside possesses potent anti-bacterial activity so it can be utilized as a potent source of antibacterial agents for food and pharmaceutical interest.

description: Empowered by large datasets, e.g., ImageNet, unsupervised learning on large-scale data has enabled significant advances for classification tasks. However, whether the large-scale unsupervised semantic segmentation can be achieved remains unknown. There are two major challenges: i) we need a large-scale benchmark for assessing algorithms; ii) we need to develop methods to simultaneously learn category and shape representation in an unsupervised manner. In this work, we propose a new problem of large-scale unsupervised semantic segmentation (LUSS) with a newly created benchmark dataset to help the research progress. Building on the ImageNet dataset, we propose the ImageNet-S dataset with 1.2 million training images and 50k high-quality semantic segmentation annotations for evaluation. Our benchmark has a high data diversity and a clear task objective. We also present a simple yet effective method that works surprisingly well for LUSS. In addition, we benchmark related un/weakly/fully supervised methods accordingly, identifying the challenges and possible directions of LUSS. The benchmark and source code is publicly available at https://github.com/LUSSeg.

description: We study the behavior of the entanglement entropy in $(2+1)$--dimensional strongly coupled theories via the AdS/CFT correspondence. We consider theories at a finite charge density with a magnetic field, with their holographic dual being Einstein-Maxwell-Dilaton theory in four dimensional anti--de Sitter gravity. Restricting to black hole and electron star solutions at zero temperature in the presence of a background magnetic field, we compute their holographic entanglement entropy using the Ryu-Takayanagi prescription for both strip and disk geometries. In the case of the electric or magnetic zero temperature black holes, we are able to confirm that the entanglement entropy is invariant under electric-magnetic duality. In the case of the electron star with a finite magnetic field, for the strip geometry, we find a discontinuity in the first derivative of the entanglement entropy as the strip width is increased.
