description: Inspired by Manjul Bhargava's theory of generalized factorials, Fedor Petrov and the author have defined the "Bhargava greedoid" -- a greedoid (a matroid-like set system on a finite set) assigned to any "ultra triple" (a somewhat extended variant of a finite ultrametric space). Here we show that the Bhargava greedoid of a finite ultra triple is always a "Gaussian elimination greedoid" over any sufficiently large (e.g., infinite) field; this is a greedoid analogue of a representable matroid. We find necessary and sufficient conditions on the size of the field to ensure this.

description: The naive combination of polymorphic effects and polymorphic type assignment has been well known to break type safety. Existing approaches to this problem are classified into two groups: one for restricting how effects are triggered and the other for restricting how they are implemented. This work explores a new approach to ensuring the safety of polymorphic effects in polymorphic type assignment. A novelty of our work lies in finding a restriction on effect interfaces. To formalize our idea, we employ algebraic effects and handlers, where an effect interface is given by a set of operations coupled with type signatures. We propose signature restriction, a new notion to restrict the type signatures of operations, and show that signature restriction is sufficient to ensure type safety of an effectful language equipped with unrestricted polymorphic type assignment. We also develop a type-and-effect system to enable the use of both operations that satisfy and do not satisfy the signature restriction in a single program.

description: The discrete unified gas kinetic scheme (DUGKS) is a new finite volume (FV) scheme for continuum and rarefied flows which combines the benefits of both Lattice Boltzmann Method (LBM) and unified gas kinetic scheme (UGKS). By reconstruction of gas distribution function using particle velocity characteristic line, flux contains more detailed information of fluid flow and more concrete physical nature. In this work, a simplified DUGKS is proposed with reconstruction stage on a whole time step instead of half time step in original DUGKS. Using temporal/spatial integral Boltzmann Bhatnagar-Gross-Krook (BGK) equation, the transformed distribution function with inclusion of collision effect is constructed. The macro and mesoscopic fluxes of the cell on next time step is predicted by reconstruction of transformed distribution function at interfaces along particle velocity characteristic lines. According to the conservation law, the macroscopic variables of the cell on next time step can be updated through its macroscopic flux. Equilibrium distribution function on next time step can also be updated. Gas distribution function is updated by FV scheme through its predicted mesoscopic flux in a time step. Compared with the original DUGKS, the computational process of the proposed method is more concise because of the omission of half time step flux calculation. Numerical time step is only limited by the Courant-Friedrichs-Lewy (CFL) condition and relatively good stability has been preserved. Several test cases, including the Couette flow, lid-driven cavity flow, laminar flows over a flat plate, a circular cylinder, and an airfoil, as well as micro cavity flow cases are conducted to validate present scheme. The numerical simulation results agree well with the references' results.

description: We study the response of critical Resonating Valence Bond (RVB) spin liquids to doping with longer-range singlets, and more generally of U(1)-symmetric tensor networks to non-symmetric perturbations. Using a field theory description, we find that in the RVB, doping constitutes a relevant perturbation which immediately opens up a gap, contrary to previous observations. Our analysis predicts a very large correlation length even at significant doping, which we verify using high-accuracy numerical simulations. This emphasizes the need for careful analysis, but also justifies the use of such states as a variational ansatz for critical systems. Finally, we give an example of a PEPS where non-symmetric perturbations do not open up a gap and the U(1) symmetry re-emerges.

description: To investigate the variables per International Classification of Functioning, Disability and Health (ICF)-domain that are associated with upper limb (UL) function in women after breast cancer surgery. PubMed and Web of Science were searched until 7 January 2020. Eligibility criteria were: prospective investigation of an association between one or more variables of the ICF model and UL function in women after breast cancer surgery. PRISMA guidelines were used to conduct and report the systematic review. The Quality In Prognosis Studies tool (QUIPS) was used to evaluate risk of bias. Twelve studies were included (2244 participants). Risk of bias of the included studies was low to moderate. Variables at the ICF-function level that were systematically associated with decreased UL function across multiple included papers were: increased UL pain, decreased shoulder range of motion, decreased handgrip strength and a higher number of comorbidities. Results on the association between UL function and variables at other ICF-domains were conflicting. UL function was associated with certain variables at the ICF-function level. Variability in disease stages, treatment and measurement methods might explain inconsistent associations with other variables. Only limited studies investigated associations between UL function and psychosocial factors.IMPLICATIONS FOR REHABILITATIONThis paper gives an overview of associations between different variables of the ICF model and UL dysfunctions in women after breast cancer surgery.Identified associated factors are situated at the ICF function level, i.e., UL pain, decreased handgrip strength and shoulder (abduction) ROM.These factors are modifiable and should be monitored, prevented and treated in physical therapy practice.UL dysfunction is not consistently associated with treatment-related variables.The role of psychosocial personal factors in UL dysfunctions should be considered and further explored.

description: En addition à la photosynthèse, la majorité des organismes phytoplanctoniques utilise aussi des substrats organiques disponible dans leur écosystème comme source d'énergie et de nutriment, par phagotrophie (i.e. englobement et digestion d'autres organismes ou particules exogènes), par kleptoplastidie (i.e. mixotrophes non-constitutifs) ou par osmotrophie (i.e. absorption de composés organiques dissouts à travers la membrane). Cette dite "mixotrophie" de la part de ces organismes est largement distribuée chez les protistes marins ce qui rend difficile de définir un organisme phytoplanctonique comme strictement autotrophe. En n'intégrant pas la mixotrophie comme un trait fonctionnel, l'estimation de la production primaire nette dans la modélisation de la communauté planctonique sous-estime l'efficacité de la pompe biologique. La mixotrophie constitue donc un trait physiologique essentiel dans la compréhension de la biodiversité structurelle et fonctionnelle du plancton marin. Il est fondamental d'élucider l'importance de la mixotrophie chez les communautés phytoplanctoniques, et particulièrement sous des conditions limitantes, afin de mieux comprendre les écosystèmes marins.La région côtière marine de la Guyane française est un système côtier complexe et unique caractérisé par une faible saisonnalité et de forts gradients environnementaux allant de la côte vers le plateau continental. Malgré le manque de variation saisonnière, un gradient de groupes de microphytoplancton différents fonctionnellement a déjà été observé se composant principalement d'autotrophes, mixotrophes puis principalement d'hétérotrophes de la côte vers le plateau continental des côtes guyanaises. Bien que plusieurs études ont décrit la succession d'espèces de microphytoplancton dans ces eaux, il persiste un manque d'information sur les communautés nanophytoplanctoniques (< 20 µm) et comment les facteurs environnementaux limitants (ici, la lumière et les nutriments) influencent la biodiversité (structurelle et fonctionnelle) et les modes nutritionnels des communautés nanophytoplanctoniques.Dans ce projet, nous proposons d'estimer l'effet de la limitation en lumière et en nutriment de la mixotrophie pour des communautés naturelles nanophytoplanctoniques. Pour cela, nous décrirons 1) l'état environnemental et métabolique des différentes masses d'eau et 2) la diversité et la capacité de la mixotrophie chez le nanophytoplancton en utilisant des méthodes moléculaires et des approches expérimentales in situ. Ce projet permettra de mieux comprendre la productivité des écosystèmes côtiers sous des limitations environnementales et d'améliorer notre concept de la boucle microbienne dans ces écosystèmes.

description: This paper focuses on the impact of various wind and waves conditions to the motion, tower base forces/moments and mooring line tension of a reference floating offshore wind turbine (FOWT) platform. The simulations are performed using the time-domain open-source software named OpenFAST to assess various operational and damaged scenarios. In total, 768 irregular wave and 384 regular wave cases are simulated. The irregular wave simulation cases includes the following combinations: 4 significant wave heights, 4 wave periods, 4 wind speeds, 2 wind fields (steady and turbulent) and 2 operational scenarios (mooring lines intact and loss of 1 fairlead). The combinations in the regular wave simulations are similar except for the wind conditions that are only simulated for 2 different wind speeds. Selective simulation results are shown to assess the impact of different hydrodynamic modelling: • potential flow, • potential flow combined with Morison drag (hybrid) • hybrid approach with the inclusion of second order wave forces via Quadratic Transfer Function (QTF). The importance of including Morison drag term is demonstrated by assessing the platform’s transient motion and the contribution of the heave disk to which the viscous effect is modelled with the Morison equation. The impact of mean-drift from the difference-frequency second-order wave forces is evaluated by analyzing the surge motion of the platform, comparing it with the potential-flow-only model. Analyzing the Power Spectral Density (PSD) of the tower base moment reveals several peaks in the frequency range corresponding to the contribution of the sum-frequency QTF. These contributions of including full QTF are assessed for different wave periods to which the impact is more apparent for shorter wave periods. Additionally, the loss of one mooring line is simulated for all wind and wave conditions. This damaged scenario changes the behavior of the platform. Not only does it give rise in the fairlead tension amplitude but also induces higher load in the lower frequencies region, visible on the PSD of the fairlead tension. Simulating a turbulent wind field is found to increase the tower base moment amplitude by up to two folds compared to the steady wind field. The wind speed fluctuation in a turbulent wind field affects the thrust force which is transferred to the tower base. Lastly, different wind directions are analyzed to assess the impact of aerodynamic load to the mooring system, keeping the same wave direction. The wind-wave misalignment induces higher peaks in the lower frequency region in the fairlead tension PSD. The dataset containing a total of 1152 simulation results are uploaded to an open-access repository and are publicly available.

description: Acoustic waves are dissipated when they pass through bubbly media. Dissipation by bubbles takes place through thermal damping (Td), radiation damping (Rd) and damping due to the friction of the liquid (Ld) and friction of the coating (Cd). Knowledge of the contributions of the Td, Rd, Ld and Cd during nonlinear bubble oscillations will help in optimizing bubble and ultrasound exposure parameters for the relevant applications by maximizing a desirable parameter. In this work we investigate the mechanisms of dissipation in bubble oscillations and their contribution to the total damping (Wtotal) in various nonlinear regimes. By using bifurcation analysis, we have classified nonlinear dynamics of bubbles that are sonicated with their 3rd superharmonic (SuH) and 2nd SuH resonance frequency (fr), pressure dependent resonance frequency (PDfr), fr, subharmonic (SH) resonance (fsh=2fr), pressure dependent SH resonance (PDfsh) and 1/3 order SH resonance. The corresponding Td, Rd, Ld, Cd, Wtotal, scattering to dissipation ratio (STDR), maximum wall velocity and maximum back-scattered pressure from non-destructive oscillations of bubbles were calculated and analyzed using the bifurcation diagrams. We classified different regimes of dissipation and provided parameter regions in which a particular parameter of interest (e.g. Rd) can be enhanced. Afterwards enhanced bubble activity is linked to some relevant applications in ultrasound. This paper represents the first comprehensive analysis of the nonlinear oscillations regimes and the corresponding damping mechanisms.

description: Semiconductor quantum light sources are favorable for a wide range of quantum photonic tasks, particularly quantum computing and quantum information processing. Here we theoretically investigate the properties of quantum emitters (QEs) as a source of entangled photons with practical quantum properties including heralding of on-demand single photons. Through the theoretical analysis, we characterize the properties of a cascade (biexciton) emitter, including (1) studies of single-photon purity, (2) investigating the first- and second- order correlation functions, and (3) determining the Schmidt number of the entangled photons. The analytical expression derived for the Schmidt number of the cascade emitters reveals a strong dependence on the ratio of decay rates of the first and second photons. Looking into the joint spectral density of the generated biphotons, we show how the purity and the degree of entanglement are connected to the production of heralded single photons.
 Our model is further developed to include polarization effects, fine structure splitting, and the emission delay between the exciton and biexciton emission. The extended model offers more details about the underlying mechanism of entangled photon production, and it provides additional degrees of freedom for manipulating the system and characterizing purity of the output photon. The theoretical investigations and the analysis provide a cornerstone for the experimental design and engineering of on-demand single photons.

description: We propose a microscopic mechanism for ultrafast skyrmion photo-excitation via a two-orbital electronic model. In the strong correlation limit the $d$-electrons are described by an effective spin Hamiltonian, coupled to itinerant $s$-electrons via $s-d$ exchange. Laser-exciting the system by a direct coupling to the electric charge leads to skyrmion nucleation on a 100 fs timescale. The coupling between photo-induced electronic currents and magnetic moments, mediated via Rashba spin-orbit interactions, is identified as the microscopic mechanism behind the ultrafast optical skyrmion excitation.

description: Motivated by the EU's "Right To Be Forgotten" regulation, we initiate a study of statistical data deletion problems where users' data are accessible only for a limited period of time. This setting is formulated as an online supervised learning task with \textit{constant memory limit}. We propose a deletion-aware algorithm \texttt{FIFD-OLS} for the low dimensional case, and witness a catastrophic rank swinging phenomenon due to the data deletion operation, which leads to statistical inefficiency. As a remedy, we propose the \texttt{FIFD-Adaptive Ridge} algorithm with a novel online regularization scheme, that effectively offsets the uncertainty from deletion. In theory, we provide the cumulative regret upper bound for both online forgetting algorithms. In the experiment, we showed \texttt{FIFD-Adaptive Ridge} outperforms the ridge regression algorithm with fixed regularization level, and hopefully sheds some light on more complex statistical models.

description: In the aerospace industry, non-destructive testing is commonly used to ensure structural integrity. Methods such as eddy current, ultrasonic and radiographic testing are applied, but often require relatively expensive equipment and experienced operators for scanning and data interpretation. Acoustic resonance testing is an objective and cost-effective method that can test entire structures. This study investigated a machine learning-based acoustic resonance testing method for predicting relative stiffness loss as an indicator of progressive damage in riveted joints. Fatigue tests were performed in which the specimens were excited by a hammer impulse and acoustic emissions were measured at intervals. Two feature extraction approaches were applied to the frequency response function and different machine learning models for the prediction. The best results were obtained using a Convolutional Neural Network. It achieved an R² of 0.98 for predicting the loss of the joint stiffness and a classification accuracy of 100 % for defect detection based on these predictions.

description: The study of first-order optimization algorithms (FOA) typically starts with assumptions on the objective functions, most commonly smoothness and strong convexity. These metrics are used to tune the hyperparameters of FOA. We introduce a class of perturbations quantified via a new norm, called *-norm. We show that adding a small perturbation to the objective function has an equivalently small impact on the behavior of any FOA, which suggests that it should have a minor impact on the tuning of the algorithm. However, we show that smoothness and strong convexity can be heavily impacted by arbitrarily small perturbations, leading to excessively conservative tunings and convergence issues. In view of these observations, we propose a notion of continuity of the metrics, which is essential for a robust tuning strategy. Since smoothness and strong convexity are not continuous, we propose a comprehensive study of existing alternative metrics which we prove to be continuous. We describe their mutual relations and provide their guaranteed convergence rates for the Gradient Descent algorithm accordingly tuned. Finally we discuss how our work impacts the theoretical understanding of FOA and their performances.

description: The group SL(2,$\mathbb{C}$) is a suitable representation for transforming Weyl spinors and two index objects equivalent to four-vectors. In this sense, the electromagnetic four-potential also transforms under the group SL(2,$\mathbb{C}$). But, second order tensors such as the Faraday tensor  does not transform under this group. However, there is an alternative way of describing the electric and magnetic fields as a complex six-dimensional object, namely the Riemann-Silberstein vector. In this note we review different ways of transforming spinors, four-vectors and electromagnetic fields and introduce representations that combine all four Maxwell equations in a single equation.

description: Superconducting transition-edge sensors (TES) are extremely sensitive microcalorimeters used as photon detectors with unparalleled energy resolution. They have found application from measuring astronomical spectra through to determining the quantum property of photon-number, $\hat{n} {=} \hat{a}^† \hat{a}$, for energies from 0.6-2.33eV. However, achieving optimal energy resolution requires considerable data acquisition -- on the order of 1GB/min -- followed by post-processing, which does not allow access to energy information in real time. Here we use a custom hardware processor to process TES pulses while new detections are still being registered, allowing photon-number to be measured in real time as well as reducing data requirements by orders-of-magnitude. We resolve photon number up to n=16 -- achieving up to parts-per-billion discrimination for low photon numbers on the fly -- providing transformational capacity for applications of TES detectors from astronomy through to quantum technology.

description: Nuclear decays with simultaneous emission of two alpha particles are energetically possible for a number of nuclides. Prospects of searching for such kind of decay for nuclides present in the natural isotopic composition of elements are discussed here. The first experimental limit on half-life for 2alpha decay is set for 209Bi as T1/2 > 2.9e20 y at 90% C.L., using the data of work [P. de Marcillac et al., Nature 422 (2003) 876]. Theoretical T1/2 estimations for the process are also given. Using these values, which are on the level of 1e33 y or more, one can conclude that the prospects of experimental observation of 2alpha decay are very pessimistic.

description: Background: The analysis of hydrophobic membrane proteins by two-dimensional gel electrophoresis has long been hampered by the concept of inherent difficulty due to solubility issues. We have optimized extraction protocols by varying the detergent composition of the solubilization buffer with a variety of commercially available non-ionic and zwitterionic detergents and detergent-like phospholipids. Results After initial analyses by one-dimensional SDS-PAGE, quantitative two-dimensional analyses of human erythrocyte membranes, mouse liver membranes, and mouse brain membranes, extracted with buffers that included the zwitterionic detergent MEGA 10 (decanoyl-N-methylglucamide) and the zwitterionic lipid LPC (1-lauroyl lysophosphatidylcholine), showed selective improvement over extraction with the common 2-DE detergent CHAPS (3 [(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate). Mixtures of the three detergents showed additive improvements in spot number, density, and resolution. Substantial improvements in the analysis of a brain membrane proteome were observed. Conclusion This study demonstrates that an optimized detergent mix, coupled with rigorous sample handling and electrophoretic protocols, enables simple and effective analysis of membrane proteomes using two-dimensional electrophoresis.

description: We propose nonabelian higher-rank gauge theories in 2+1D and 3+1D. The gauge group is constructed from the volume-preserving diffeomorphisms of space. We show that the intriguing physics of the lowest Landau level (LLL) limit can be interpreted as the consequences of the symmetry. We derive the renowned Girvin-MacDonald-Platzman (GMP) algebra as well as the topological Wen-Zee term within our formalism. Using the gauge symmetry in 2+1D, we derive the LLL effective action of vortex crystal in rotating Bose gas as well as Wigner crystal of electron in an applied magnetic field. We show that the nonlinear sigma models of ferromagnets in 2+1D and 3+1D exhibit the higher-rank gauge symmetries that we introduce in this paper. We interpret the fractonic behavior of the excitations on the lowest Landau level and of skyrmions in ferromagnets as the consequence of the higher-rank gauge symmetry.

Proportional Import Restraints in Oligopoly

description: We study the differences in the impact of trade restrictions on the level of imports (e.g. 200,000 automobiles per years) and restrictions defined in terms of market shares (e.g. 10% of the market). We argue that if domestic firms enjoy some market power proportional trade restrictions have a stronger anticompetitive effect than volume restrictions, and therefore lead to higher equilibrium prices and lower social welfeare. In the case of Cournot competition and constant marginal costs, with proportional import restraints the equilibrium price sticks to the autarchic level, independently of the market share reserved for foreign firms. As a consequence, enlarging the share of imports does not increase consumers surplus and negatively affects the profits of domestic firms, thus lowering social welfare.
Multivariate Estimation of Exponential Affine Models of the Term Structure of Interest Rates

description: In this paper I consider the estimation of multi-factor exponential affine models of the term structure of interest rates. I start with a survey of the empirical work on the term structure in continuous time, showing that in most cases the implementation of the models has not fully exploited the theoretical restrictions. I also show that these works have almost always focused on “generalizations” of the theoretical model based on the inclusion of measurement errors in bills and bonds prices. I then suggest two approaches to statistical inference: the first is based on the Kalman filter, while the second follows the indirect inference approach. I also briefly discuss the relative properties of the two estimators, and I conclude with a  small Monte Carlo experiment for a one-factor Cox-Ingersoll-Ross model, whose results are rather encouraging.
Profit Sharing Regulation, Repeated Bargaining and Shut-Down Option

Subjects: SECS-P/02 Politica economica

description: We analyse the behavior of a firm where workers share profits with shareholders by using a model cast in an Aoki framework. Our firm faces two sorts of uncertainty: one relates to the market price assumed to follow a random walk in continuous time and the other relates to internal organization, i.e. the share of profits to be distributed between workers and shareholders. The firm  is assumed to be flexible, since it has the possibility of shutting down by paying laid off workers a bonus, which represents a sunk cost for the firm. The distributive share is determined through a bargaining that takes place in two occasions: at the beginning of the firm’s life and when its profits reach a certain threshold level. The second bargaining is then endogenized according to a rule that is imposed upon shareholders and workers by a regulator who may use profit distribution as a way to regulate the firm. Different share parameter patterns will result as the regulator calls for renegotiation when profits are increasing or decreasing. Moreover we distinguish between a case in which the regulator’s rule is announced in advance from the one in which it is discretionally set.
