description: This paper is dedicated to the memory of Moshe Flato, and will appear in Lett. Math. Phys. 48 (1) It became clear during last 5-6 years that the algebraic world of associative algebras (abelian categories, triangulated categories, etc) has many deep connections with the geometric world of two-dimensional surfaces. One of manifestations of this is Deligne's conjecture (1993) which says that on the cohomological Hochschild complex of any associative algebra naturally acts the operad of singular chains in the little discs operad. Recently D. Tamarkin discovered that the operad of chains of the little discs operad is formal, i.e. it is homotopy equivalent to its cohomology. From this fact and from Deligne's conjecture follows almost immediately my formality result in deformation quantization. I review the situation as it looks now. Also I conjecture that the motivic Galois group acts on deformation quantizations, and speculate on possible relations of higher-dimensional algebras and of motives to quantum field theories.

description: Next-generation personalized healthcare devices are undergoing extreme miniaturization in order to improve user acceptability. However, such developments make it difficult to incorporate cryptographic primitives using available target technologies since these algorithms are notorious for their energy consumption. Besides, strengthening these schemes against side-channel attacks further adds to the device overheads. Therefore, viable alternatives among emerging technologies are being sought. In this work, we investigate the possibility of using memristors for implementing lightweight encryption. We propose a 40-nm RRAM-based GIFT-cipher implementation using a 1T1R configuration with promising results; it exhibits roughly half the energy consumption of a CMOS-only implementation. More importantly, its non-volatile and reconfigurable substitution boxes offer an energy-efficient protection mechanism against side-channel attacks. The complete cipher takes 0.0034 mm$^2$ of area, and encrypting a 128-bit block consumes a mere 242 pJ.

description: The Anthropocene will be characterized by increased environmental disturbances, leading to the survival of stress-tolerant organisms particularly in the oceans where novel marine diseases and elevated temperatures are re-shaping ecosystems. These environmental changes underscore the importance of identifying mechanisms which promote stress tolerance in ecologically important non-model species such as reef-building corals. Mitochondria are central regulators of cellular stress and have dedicated recovery pathways including the mitochondrial unfolded protein response, which increases the transcription of protective genes promoting protein homeostasis, free radical detoxification and innate immunity. In this investigation, we identify a mitochondrial unfolded protein response in the endangered Caribbean coral Orbicella faveolata, by performing in vivo functional replacement using a transcription factor (Of-ATF5) originating from a coral in the model organism Caenorhabditis elegans. In addition, we use RNA-seq network analysis and transcription factor-binding predictions to identify a transcriptional network of genes likely regulated by Of-ATF5 which is induced during the immune challenge and temperature stress. Overall, our findings uncover a conserved cellular pathway which may promote the ability of reef-building corals to survive increasing levels of environmental stress.

description: Observed spectral profiles of emission lines from the corona are found to have widths exceeding the thermal line width. To investigate the physical mechanism, we run a 3D MHD model of a single, straightened loop in which we partially resolve turbulent motions that form in response to the driving by self-consistently evolving magneto-convection in the photosphere. The convective motions shear and twist the magnetic field lines, leading to heating. From the model we synthesize spectral profiles of emission lines forming at temperatures around and above 1 MK. The coronal heating process generates a range of velocity amplitudes and directions structured on a scale much smaller than the resolving power of current instruments, leading to a broadening of the spectral lines. Our model includes the mass exchange between corona and chromosphere, thus we also capture flows parallel to the loop axis. We find that the spectral lines show a non-thermal line broadening roughly consistent with observations for a viewing angle perpendicular to the axis. The broadening through field-parallel flows is comparable, although slightly smaller. The line broadening is independent of the instrument resolution for a perpendicular line-of-sight. We can connect the non-thermal line broadening to heating events and flows. While small-scale velocities along the line-of-sight are mainly responsible for the broadening observed perpendicular to the loop, chromospheric evaporation is important for the line broadening observed along the loop. The model reproduces observed values for non-thermal line widths. In the model these result from continuous driving by magnetoconvection, without imposing driving motions or starting from an already braided field.

description: Visualization research tends to de-emphasize consideration of the textual context in which its images are placed. We argue that visualization research should consider textual representations as a primary alternative to visual options when assessing designs, and when assessing designs, equal attention should be given to the construction of the language as to the visualizations. We also call for a consideration of readability when integrating visualizations with written text. In highlighting these points, visualization research would be elevated in efficacy and demonstrate thorough accounting for viewers' needs and responses.

description: Online social networking is a pervasive but empirically understudied phenomenon. Strong public opinions on its consequences exist but are backed up by little empirical evidence and almost no causally conclusive, experimental research. The current study tested the psychological effects of posting status updates on Facebook using an experimental design. For 1 week, participants in the experimental condition were asked to post more than they usually do, whereas participants in the control condition received no instructions. Participants added a lab “Research Profile” as a Facebook friend allowing for the objective documentation of protocol compliance, participants’ status updates, and friends’ responses. Results revealed (1) that the experimentally induced increase in status updating activity reduced loneliness, (2) that the decrease in loneliness was due to participants feeling more connected to their friends on a daily basis, and (3) that the effect of posting on loneliness was independent of direct social feedback (i.e., responses) by friends.

description: The q-Laguerre polynomials correspond to an indetermined moment problem. For explicit discrete non-N-extremal measures corresponding to Ramanujan's ${}_1ψ_1$-summation we complement the orthogonal q-Laguerre polynomials into an explicit orthogonal basis for the corresponding L^2-space. The dual orthogonal system consists of so-called big q-Bessel functions, which can be obtained as a rigorous limit of the orthogonal system of big q-Jacobi polynomials. Interpretations on the SU(1,1) and E(2) quantum groups are discussed.

description: Maximal abelian subalgebras of one of the classical real inhomogeneous Lie algebras are constructed, namely those of the pseudoeuclidean Lie algebra e(p,q). Use is made of the semidirect sum structure of e(p,q) with the translations T(p+q) as an abelian ideal. We first construct splitting MASAs that are themselves direct sums of abelian subalgebras of o(p,q) and of subalgebras of T(p+q). The splitting subalgebras are used to construct the complementary nonsplitting ones. We present general decomposition theorems and construct indecomposable MASAs for all algebras e(p,q), p \geq q \geq 0. The case of q=0 and 1 were treated earlier in a physical context. The case q=2 is analyzed here in detail as an illustration of the general results.

description: The unique functionalities of antiferromagnets offer promising routes to advance information technology. Their compensated magnetic order leads to spin resonances in the THz-regime, which suggest the possibility to coherently control antiferromagnetic (AFM) devices orders of magnitude faster than traditional electronics. However, the required time resolution, complex sublattice interations and the relative inaccessibility of the AFM order parameter pose serious challenges to studying AFM spin dynamics. Here, we reveal the temporal evolution of an AFM order parameter directly in the time domain. We modulate the AFM order in hexagonal YMnO$_\mathrm{3}$ by coherent magnon excitation and track the ensuing motion of the AFM order parameter using time-resolved optical second-harmonic generation (SHG). The dynamic symmetry reduction by the moving order parameter allows us to separate electron dynamics from spin dynamics. As transient symmetry reductions are common to coherent excitations, we have a general tool for tracking the ultrafast motion of an AFM order parameter.

The plant part extracts of the 6-year-old Dendropanax morbiferus in high concentration (see methods and materials for concentration) had the effects on the increase of oligodendrocyte membrane size with following order; leaf > root > stem. The 6-year-old Dendropanax morbiferus leaf extracts induced a bigger oligodendrocyte membrane size compared to 20-year-old leaf extracts. The low concentration of the extracts induced a smaller impact on oligodendrocyte membrane size compared to the high concentration.

description: Genome-wide association studies are experiments designed to find the genetic bases of physical traits: for example, markers correlated with disease status by comparing the DNA of healthy individuals to the DNA of affecteds. Over the past two decades, an exponential increase in the resolution of DNA-testing technology coupled with a substantial drop in their cost have allowed us to amass huge and potentially invaluable datasets to conduct such comparative studies. For many common diseases, datasets as large as a hundred thousand individuals exist, each tested at million(s) of markers (called SNPs) across the genome. Despite this treasure trove, so far only a small fraction of the genetic markers underlying most common diseases have been identified. Simply stated - our ability to predict phenotype (disease status) from a person's genetic constitution is still very limited today, even for traits that we know to be heritable from one's parents (e.g. height, diabetes, cardiac health). As a result, genetics today often lags far behind conventional indicators like family history of disease in terms of its predictive power. To borrow a popular metaphor from astronomy, this veritable "dark matter" of perceivable but un-locatable genetic signal has come to be known as missing heritability. This thesis will present my research contributions in two hotly pursued scientific hypotheses that aim to close this gap: (1) gene-gene interactions, and (2) ultra-rare genetic variants - both of which are not yet widely tested. First, I will discuss the challenges that have made interaction testing difficult, and present a novel approximate statistic to measure interaction. This statistic can be exploited in a Monte-Carlo like randomization scheme, making an exhaustive search through trillions of potential interactions tractable using ordinary desktop computers. A software implementation of our algorithm found a reproducible interaction between SNPs in two calcium channel genes in Bipolar Disorder. Next, I will discuss the functional enrichment pipeline we subsequently developed to identify sets of interacting genes underlying this disease. Lastly, I will talk about the application of coding theory to cost-efficient measurement of ultra-rare genetic variation (sometimes, as rare as just one individual carrying the mutation in the entire population).

description: In this work, we present a reinforcement learning algorithm that can find a variety of policies (novel policies) for a task that is given by a task reward function. Our method does this by creating a second reward function that recognizes previously seen state sequences and rewards those by novelty, which is measured using autoencoders that have been trained on state sequences from previously discovered policies. We present a two-objective update technique for policy gradient algorithms in which each update of the policy is a compromise between improving the task reward and improving the novelty reward. Using this method, we end up with a collection of policies that solves a given task as well as carrying out action sequences that are distinct from one another. We demonstrate this method on maze navigation tasks, a reaching task for a simulated robot arm, and a locomotion task for a hopper. We also demonstrate the effectiveness of our approach on deceptive tasks in which policy gradient methods often get stuck.

description: We observe and measure the nonequilibrium dynamics of optical vortices as a function of propagation distance through a nonlinear medium. The precession of a tilted-core vortex is quantified as is vortex-core sharpening, where the infinite width of a linear core subsequently shrinks and approaches the healing length of this nonlinear optical fluid. Experiments are performed with a variable-length nonlinear medium: a nonlinear fluid in a tank with an output window on a translating tube. This provides control over the distance the light propagates in the fluid and allows for the measurement of the dynamics throughout the entire propagation range. Results are compared to the predictions of a computational simulator to find the equivalent dimensionless nonlinear coefficient.

description: Autism spectrum disorders (ASDs) are characterized by phenotypic and genetic heterogeneity. Our analysis of functional networks perturbed in ASD suggests that both truncating and non-truncating de novo mutations contribute to autism. Moreover, we find that truncating mutations affecting the same exon lead to strikingly similar intellectual phenotypes in unrelated ASD probands and propose that exons, rather than genes, represent a unit of effective phenotypic impact for truncating mutations in autism. The phenotypic effects are likely mediated by nonsense-mediated decay of splicing isoforms and similar patterns may be observed in other genetic disorders. While multiple cell types and brain areas are affected, the impact of ASD mutations converge on a strongly interconnected system of neural structures that involve basal ganglia loops and the limbic system. We observe that distant projections constitute a disproportionately large fraction of the network composition, suggesting that the integration of diverse brain regions is a key property of the neural circuit. We demonstrate that individual de novo mutations impact several disparate components of the network and may further explain the phenotypic variability. Overall, our study presents a method that, to our knowledge, is the first unbiased approach using genetic variants to comprehensively discover and identify the neural circuitry affected in a psychiatric disorder.

description: Gameplay under various forms of uncertainty has been widely studied. Feldman et al. (2010) studied a particularly low-information setting in which one observes the opponent's actions but no payoffs, not even one's own, and introduced an algorithm which guarantees one's payoff nonetheless approaches the minimax optimal value (i.e., zero) in a symmetric zero-sum game. Against an opponent playing a minimax-optimal strategy, approaching the value of the game is the best one can hope to guarantee. However, a wealth of research in behavioral economics shows that people often do not make perfectly rational, optimal decisions. Here we consider whether it is possible to actually win in this setting if the opponent is behaviorally biased. We model several deterministic, biased opponents and show that even without knowing the game matrix in advance or observing any payoffs, it is possible to take advantage of each bias in order to win nearly every round (so long as the game has the property that each action beats and is beaten by at least one other action). We also provide a partial characterization of the kinds of biased strategies that can be exploited to win nearly every round, and provide algorithms for beating some kinds of biased strategies even when we don't know which strategy the opponent uses.

 Espèce type: Libellula aurora Burmeister, 1839.
Taille petite à moyenne (L.: 30 à 40 mm), allure générale assez fine; front arrondi ou présentant une carène antérieure, avec ou sans reflets métalliques; anténodales en nombre variable, de 8 1/2 à 15 1/2, la dernière toujours incomplète; abdomen assez fin, peu ou pas dilaté à la base.
 Les Trithemis des environs du Nimba, comme les autres Trithemis afrotropicaux se répartissent en deux grands groupes (Pinhey 1970b). Le premier est constitué des espèces dont la couleur générale est rougeâtre (annulata, arteriosa, kalula et kirbyi ardens) et le second groupe par des espèces plutôt noires (aconita, atra, dichroa, dorsalis, furva et pruinata). Si pour les mâles la distinction entre les espèces est parfois nette, il n’en va pas de même pour les femelles (même pour un spécialiste) qui sont beaucoup moins souvent capturées, car beaucoup plus discrètes.

description: In this paper, we introduce the isoGeometric Residual Minimization (iGRM) method. The method solves stationary advection-dominated diffusion problems. We stabilize the method via residual minimization. We discretize the problem using B-spline basis functions. We then seek to minimize the isogeometric residual over a spline space built on a tensor product mesh. We construct the solution over a smooth subspace of the residual. We can specify the solution subspace by reducing the polynomial order, by increasing the continuity, or by a combination of these. The Gramm matrix for the residual minimization method is approximated by a weighted H1 norm, which we can express as Kronecker products, due to the tensor-product structure of the approximations. We use the Gramm matrix as a preconditional which can be applied in a computational cost proportional to the number of degrees of freedom in 2D and 3D. Building on these approximations, we construct an iterative algorithm. We test the residual minimization method on several numerical examples, and we compare it to the Discontinuous Petrov-Galerkin (DPG) and the Streamline Upwind Petrov-Galerkin (SUPG) stabilization methods. The iGRM method delivers similar quality solutions as the DPG method, it uses smaller grids, it does not require breaking of the spaces, but it is limited to tensor-product meshes. The computational cost of the iGRM is higher than for SUPG, but it does not require the determination of problem specific parameters.

description: Motivated by the Weyl scaling gauge symmetry, we present a theoretical framework to explain cosmic inflation and dark matter simultaneously. This symmetry has been resurrected in recent attempts to formulate the gauge theory of gravity. We show the inspired inflation model is well consistent with current observations and will be probed further by future experiments. Furthermore, we clarify and prove the stability of Weyl gauge boson in the general theory with multiple scalars. We show the massive Weyl gauge boson can be a dark matter candidate and give the correct relic abundance.

description: [transcription] Monsieur
Monsieur l’abbé Pourret n’ayant pas pu obtenir la permission de sortir aujourd’hui pour aller à son jardin, m’a remis une boîte remplie de sedum qu’il a retiré de la poste. Comme la plupart de ces plantes étaient étiollées ou sèches, il m’a chargé d’aller les renouveller, mais d’y mettre de chaque espèce en moindre quantité et d’achever de remplir la boîte avec quelques plantes bulbeuses dont il m’a donné la liste. Quoique monsieur Pourret veuille bien me confier le soin de son jardin, je n’ai pas été encore assez à même de profiter de ses leçons ; et je n’ai pas acquis assez d’usage pour reconnaître les plantes lorsquelles sont sans fleurs.
Si monsieur Pech n’eut pas été absent, je l’aurais prié de m’aider à faire ce choix. Mais seul, je n’ai pas osé me hasarder de le faire crainte de me tromper, de vous envoyer des [fol. 114 v] choses inutiles, et de les priver d’autres plantes intéressantes qu’ils doivent d’autant plus ménager que monsieur Pourret en reçoit sans cesse de tout côté et qu’il est quelque fois de mauvaise humeur lorsqu’il ne peut pas donner ce qu’on lui demande. J’ai pris pour cet effet une plus petite boîte afin de ne pas surcharger la personne qui s’en chargera.
Il est bien fâcheux pour moi que pour la première fois que je me faisais une fête d’être employé à votre service, ne désirant que de vous offrir mon tribut d’hommages et d’admiration, je n’aie que des excuses à vous faire. Je me flatte que je serai plus heureux dans la préparation des plantes sèches que je vais commencer. Je m’apliquerai avec un zèle particulier à celles que je saurai vous être destinées, et je fournirai par là à monsieur Pourret, à qui je dois cette attention pour l’amitié qu’il a pour moi, de vous donner des nouvelles preuves de son attachement. Car je sais qu’il a un plaisir infini à s’occuper de ce qui peut vous être agréable et il n’est jamais si content que lorsqu’il nous parle de vous.
Veuillez bien excuser la liberté que je prends dans le moment. Mais vous ne me connaissez pas et je n’ai rien à craindre, il me suffit de vous dire Monsieur que partout l’on vous aime et l’on vous admire et qu’il est peu de savants qui le méritent autant que vous.
[fol. 115 r] J’ai l’honneur d’être avec un profond respect,
Monsieur,

Votre très humble et très obéissant serviteur

Circle Back Next Week: The Effect of Meeting-Free Weeks on Distributed Workers' Unstructured Time and Attention Negotiation

description: While distributed workers rely on scheduled meetings for coordination and collaboration, these meetings can also challenge their ability to focus. Protecting worker focus has been addressed from a technical perspective, but companies are now attempting organizational interventions, such as meeting-free weeks. Recognizing distributed collaboration as a sociotechnical challenge, we first present an interview study with distributed workers participating in meeting-free weeks at an enterprise software company. We identify three orientations workers exhibit during these weeks: Focus, Collaborative, and Time-Bound, each with varying levels and use of unstructured time. These different orientations result in challenges in attention negotiation, which may be suited for technical interventions. This motivated a follow-up study investigating attention negotiation and the compensating mechanisms workers developed during meeting-free weeks. Our framework identified tensions between the attention-getting and attention-delegation strategies. We extend past work to show how workers adapt their virtual collaboration mechanisms in response to organizational interventions

Variational symmetries and pluri-Lagrangian structures for integrable hierarchies of PDEs

description: We investigate the relation between pluri-Lagrangian hierarchies of $2$-dimensional partial differential equations and their variational symmetries. The aim is to generalize to the case of partial differential equations the recent findings in [Petrera, Suris. J. Nonlinear Math. Phys. 24:sup1, 121--145 (2017)] for ordinary differential equations. We consider hierarchies of $2$-dimensional Lagrangian PDEs (many of which have a natural $(1+1)$-dimensional space-time interpretation) and show that if the flow of each PDE is a variational symmetry of all others, then there exists a pluri-Lagrangian 2-form for the hierarchy. The corresponding multi-time Euler-Lagrange equations coincide with the original system supplied with commuting evolutionary flows induced by the variational symmetries.

description: The spin-$\frac{1}{2}$ kagome antiferromagnet is considered an ideal host for a quantum spin liquid ground state. We find that when the bonds of the kagome lattice are modulated with a periodic pattern, new quantum ground states emerge. Newly synthesized crystalline barlowite (Cu$_4$(OH)$_6$FBr) and Zn-substituted barlowite demonstrate the delicate interplay between singlet states and spin order on the spin-$\frac{1}{2}$ kagome lattice. Comprehensive structural measurements demonstrate that our new variant of barlowite maintains hexagonal symmetry at low temperatures with an arrangement of distorted and undistorted kagome triangles, for which numerical simulations predict a pinwheel valence bond crystal (VBC) state instead of a quantum spin liquid (QSL). The presence of interlayer spins eventually leads to an interesting pinwheel $q=0$ magnetic order. Partially Zn-substituted barlowite (Cu$_{3.44}$Zn$_{0.56}$(OH)$_6$FBr) has an ideal kagome lattice and shows QSL behavior, indicating a surprising robustness of the QSL against interlayer impurities. The magnetic susceptibility is similar to that of herbertsmithite, even though the Cu$^{2+}$ impurities are above the percolation threshold for the interlayer lattice and they couple more strongly to the nearest kagome moment. This system is a unique playground displaying QSL, VBC, and spin order, furthering our understanding of these highly competitive quantum states.

description: Feedback control mechanisms are ubiquitous in science and technology, and play an essential role in regulating physical, biological and engineering systems. The standard second law of thermodynamics does not hold in the presence of measurement and feedback. Most studies so far have extended the second law for discrete, Markovian feedback protocols; however, non-Markovian feedback is omnipresent in processes where the control signal is applied with a non-negligible delay. Here, we experimentally investigate the thermodynamics of continuous, time-delayed feedback control using the motion of an optically levitated, underdamped microparticle. We test the validity of a generalized second law which bounds the energy extracted from the system and study the breakdown of feedback cooling for very large time delays.
