description: In this work, we propose a tube-based MPC scheme for state- and input-constrained linear systems subject to dynamic uncertainties characterized by dynamic integral quadratic constraints (IQCs). In particular, we extend the framework of $ρ$-hard IQCs for exponential stability analysis to external inputs. This result yields that the error between the true uncertain system and the nominal prediction model is bounded by an exponentially stable scalar system. In the proposed tube-based MPC scheme, the state of this error bounding system is predicted along with the nominal model and used as a scaling parameter for the tube size. We prove that this method achieves robust constraint satisfaction and input-to-state stability despite dynamic uncertainties and additive bounded disturbances. A numerical example demonstrates the reduced conservatism of this IQC approach compared to state-of-the-art robust MPC approaches for dynamic uncertainties.

description: This Technology Assessment Report from the B.C. Office of Technology Assessment (BCOHTA) was requested by the Vancouver General Hospital (VGH) in response to suggestions by Clinical Staff that Hyperbaric Oxygen (HBO) use for chronic osteomylelitis (COM) and osteoradionecrosis (ORN) should be assessed. Thus, the VGH felt it would be useful to obtain an overview of the available scientific evidence on the efficacy and effectiveness of HBO for these two conditions.

description: Recently, Beierle and Leander found two new sporadic quadratic APN permutations in dimension 9. Up to EA-equivalence, we present a single trivariate representation of those two permutations as $C_u \colon (\mathbb{F}_{2^m})^3 \rightarrow (\mathbb{F}_{2^m})^3, (x,y,z) \mapsto (x^3+uy^2z, y^3+uxz^2,z^3+ux^2y)$, where $m=3$ and $u \in \mathbb{F}_{2^3}\setminus\{0,1\}$ such that the two permutations correspond to different choices of $u$. We then analyze the differential uniformity and the nonlinearity of $C_u$ in a more general case. In particular, for $m \geq 3$ being a multiple of 3 and $u \in \mathbb{F}_{2^m}$ not being a 7-th power, we show that the differential uniformity of $C_u$ is bounded above by 8, and that the linearity of $C_u$ is bounded above by $8^{1+\lfloor \frac{m}{2} \rfloor}$. Based on numerical experiments, we conjecture that $C_u$ is not APN if $m$ is greater than $3$. We also analyze the CCZ-equivalence classes of the quadratic APN permutations in dimension 9 known so far and derive a lower bound on the number of their EA-equivalence classes. We further show that the two sporadic APN permutations share an interesting similarity with Gold APN permutations in odd dimension divisible by 3, namely that a permutation EA-inequivalent to those sporadic APN permutations and their inverses can be obtained by just applying EA transformations and inversion to the original permutations.
Digitalizzazione del lavoro e cambiamenti del controllo manageriale

description: This paper contributes to the debate on the relationship between the digitalisation of work and managerial control, by highlighting the general directions in which this relationship has developed over time since the 1990s.

While most existing studies “squeeze” the analysis into the present, our research examines whether the change in the modes of managerial control is developing along a general trend line across different sectors and activities, and whether digitalisation is influencing it, and in which direction. Based on data from the 6th and 7th waves of the European Working Conditions Survey, the analysis provides empirical support for the thesis that digitalisation is blurring the boundaries between industrial and service work, and to some extent also between manual and intellectual work, accentuating a general movement towards a form of managerial control based on the permanent dialectic between autonomy and control that has been affecting the world of work for several decades.

description: Although much is known about the metastable liquid branch of hard spheres--from low dimension $d$ up to ${d\to\infty}$--its crystal counterpart remains largely unexplored for $d>3$. In particular, it is unclear whether the crystal phase is thermodynamically stable in high dimensions and thus whether a mean-field theory of crystals can ever be exact. In order to determine the stability range of hard sphere crystals, their equation of state is here estimated from numerical simulations, and fluid-crystal coexistence conditions are determined using a generalized Frenkel-Ladd scheme to compute absolute crystal free energies. The results show that the crystal phase is stable at least up to $d=10$, and the dimensional trends suggest that crystal stability likely persists well beyond that point.

description: We report phase separation and liquid-crystal ordering induced by scalar activity in a system of Soft Repulsive Spherocylinders (SRS) of aspect ratio $L/D = 5 $. Activity was introduced by increasing the temperature of half of the SRS (labeled \textit{`hot'}) while maintaining the temperature of the other half constant at a lower value (labeled \textit{`cold'}). The difference between the two temperatures scaled by the lower temperature provides a measure of the activity. Starting from different equilibrium initial phases, we find that activity leads to segregation of the hot and cold particles. Activity also drives the cold particles through a phase transition to a more ordered state and the hot particles to a state of less order compared to the initial equilibrium state. The cold components of a homogeneous isotropic (I) structure acquire nematic (N) and, at higher activity, crystalline (K) order. Similarly, the cold zone of a nematic initial state undergoes smectic (Sm) and crystal ordering above a critical value of activity while the hot component turns isotropic. We find that the hot particles occupy a larger volume and exert an extra kinetic pressure, confining, compressing and provoking an ordering transition of the cold-particle domains.

description: A hybrid Potts model where a random concentration $p$ of the spins assume $q_0$ states and a random concentration $1-p$ of the spins assume $q>q_0$ states is introduced. It is known that when the system is homogeneous, with an integer spin number $q_0$ or $q$, it undergoes a second or a first order transition, respectively. It is argued that there is a concentration $p^\ast$ such that the transition nature of the model is changed at $p^\ast$. This idea is demonstrated analytically and by simulations for two different types of interaction: the usual square lattice nearest neighboring and mean field all-to-all. Exact expressions for the second order critical line in concentration-temperature parameter space of the mean field model together with some other related critical properties, are derived.

description: Quantum fluctuations play a central role in the properties of quantum matter. In non-interacting ensembles, they manifest as fluctuations of non-commuting observables, quantified by Heisenberg inequalities. In the presence of interactions, additional quantum fluctuations appear, from which many-body correlations and entanglement arise. In the context of many-body physics, the Bogoliubov theory provides us with an illuminating microscopic picture of how this occurs for weakly-interacting bosons, with the appearance of the quantum depletion formed by pairs of bosons with opposite momenta. Here, we report the observation of these atom pairs in the depletion of an equilibrium interacting Bose gas. A quantitative study of atom-atom correlations, both at opposite and close-by momenta, allows us to fully characterise the equilibrium many-body state. We show that the atom pairs share the properties of two-mode squeezed states, including relative number squeezing. Our results illustrate how interacting systems acquire non-trivial quantum correlations as a result of the interplay between quantum fluctuations and interactions

description: In this paper, we explore the role of Instance Normalization in low-level vision tasks. Specifically, we present a novel block: Half Instance Normalization Block (HIN Block), to boost the performance of image restoration networks. Based on HIN Block, we design a simple and powerful multi-stage network named HINet, which consists of two subnetworks. With the help of HIN Block, HINet surpasses the state-of-the-art (SOTA) on various image restoration tasks. For image denoising, we exceed it 0.11dB and 0.28 dB in PSNR on SIDD dataset, with only 7.5% and 30% of its multiplier-accumulator operations (MACs), 6.8 times and 2.9 times speedup respectively. For image deblurring, we get comparable performance with 22.5% of its MACs and 3.3 times speedup on REDS and GoPro datasets. For image deraining, we exceed it by 0.3 dB in PSNR on the average result of multiple datasets with 1.4 times speedup. With HINet, we won 1st place on the NTIRE 2021 Image Deblurring Challenge - Track2. JPEG Artifacts, with a PSNR of 29.70. The code is available at https://github.com/megvii-model/HINet.

description: Rare-earth ions are promising solid state systems to build light-matter interfaces at the quantum level. This relies on their potential to show narrow optical homogeneous linewidths or, equivalently, long-lived optical quantum states. In this letter, we report on europium molecular crystals that exhibit linewidths in the 10s of kHz range, orders of magnitude narrower than other molecular centers. We harness this property to demonstrate efficient optical spin initialization, coherent storage of light using an atomic frequency comb, and optical control of ion-ion interactions towards implementation of quantum gates. These results illustrate the utility of rare-earth molecular crystals as a new platform for photonic quantum technologies that combines highly coherent emitters with the unmatched versatility in composition, structure, and integration capability of molecular materials.

description: Recent experiments have revealed the tantalizing possibility of fabricating lattice electronic systems strongly coupled to quantum fluctuations of electromagnetic fields, e.g., by means of geometry confinement from a cavity or artificial gauge fields in quantum simulators. In this work, we develop a high-frequency expansion to construct the effective models for lattice electrons strongly coupled to a continuum of off-resonant photon modes with arbitrary dispersion. The theory is nonperturbative in the light-matter coupling strength, and is therefore particularly suitable for the ultrastrong light-matter coupling regime. Using the effective models, we demonstrate how the dispersion and topology of the electronic energy bands can be tuned by the cavity. In particular, quasi-one-dimensional physics can emerge in a two-dimensional square lattice due to a spatially anisotropic band renormalization, and a topologically nontrivial anomalous quantum Hall state can be induced in a honeycomb lattice when the cavity setup breaks time-reversal symmetry. We also demonstrate that the photon-mediated interaction induces an unconventional superconducting paired phase distinct from the pair-density-wave state discussed in models with truncated light-matter coupling. Finally, we study a realistic setup of a Fabry-Pérot cavity. Our work provides a systematic framework to explore the emergent phenomena due to strong light-matter coupling and points out new directions of engineering orders and topological states in solids.
BioExcel Webinar #17 - MDStudio, microservice based molecular dynamics workflows
Creators: name: van Dijk, Marc
Publisher: name: Zenodo
Year: 2017
Subjects: webinar

description: Molecular Dynamics (MD) is becoming an essential method in the research toolkit of academic and applied science. Common practice is to combine MD with other in silico modelling, simulation and data analysis techniques into functional workflows. These have become complex entities over the years with significant software and hardware requirements and domain-level expertise to be handled correctly, preventing routine use by novice and expert users alike. Our Molecular and Computational Toxicology research group at the Vrije Universiteit Amsterdam develops MD-based workflows with a practical focus on drug development. To ensure user-friendliness of our workflows and promote wide-spread application of MD-based methods we have recently launched the MDStudio software platform. MDStudio uses the modern concept of “software as microservices” as the basis of constructing workflows with a number of major benefits: Open platform approach: any method can become a microservice through a thin language agnostic container exposing a standardized API to talk to others via a router over a network regardless of the database, hardware and software environment. Interoperability guaranteed! Flexible workflows: Users can interact with microservices and implement workflows at several levels of abstraction in a near language agnostic way: script based, re-computable interactive notebooks or a full graphical user interface. Fast workflow based prototyping and development making the impact of MDStudio truly greater than the sum of its parts! (Multi) user-friendly: Research is teamwork! MDStudio is multi-user ready enabling research teams to collaborate on projects through workflows, anywhere, anytime and anyplace. Heterogeneous scalability: MDStudio uses a self-contained, containerized, client-server architecture that can be deployed on many different platforms. Microservices natively scale from multi-core desktops to HPC clusters and cloud environments. Requiring only a network connection to communicate, they can be deployed on physically isolated hardware tailored to the requirements of a research team.

description: This essay explores the relationship between knowledge (in the form of scientific risk assessment) and action (in the form of technological innovation) as they come together in policy, which itself is both a kind of knowing and acting. It first illustrates the dilemma of timely action in the face of uncertain unintended consequences. It then introduces the precautionary and proactionary principles as different alignments of knowledge and action within the policymaking process. The essay next considers a cynical and a hopeful reading of the role of these principles in public policy debates. We argue that the two principles, despite initial appearances, are not all that different when it comes to formulating public policy. We also suggest that principles in general can be used either to guide our actions, or to determine them for us. We argue that allowing principles to predetermine our actions undermines the sense of autonomy necessary for true action.

description: A plasmon is a collective excitation of electrons due to the Coulomb interaction. Both plasmons and single-particle excitations (SPEs) are eigenstates of bulk metallic systems and they are orthogonal to each other. However, in non-translationally symmetric systems such as nanostructures, plasmons and SPEs coherently interact. It has been well discussed that the plasmons and SPEs, respectively, can couple with transverse (T) electric field in such systems, and also that they are coupled with each other via longitudinal (L) field. However, there has been a missing link in the previous studies: the coherent coupling between the plasmons and SPEs mediated by the T field. Herein, we develop a theoretical framework to describe the self-consistent relationship between plasmons and SPEs through both the L and T fields. The excitations are described in terms of the charge and current densities in a constitutive equation with a nonlocal susceptibility, where the densities include the L and T components. The electromagnetic fields originating from the densities are described in terms of the Green's function in the Maxwell equations. The T field is generated from both densities, whereas the L component is attributed to the charge density only. We introduce a four-vector representation incorporating the vector and scalar potentials in the Coulomb gauge, in which the T and L fields are separated explicitly. The eigenvalues of the matrix for the self-consistent equations appear as the poles of the system excitations. The developed formulation enables to approach unknown mechanisms for enhancement of the coherent coupling between plasmons and the hot carriers generated by radiative fields.

Up to equivalence of categories, the simplex category $Δ$, Segal's category $Γ$, Connes cyclic category $Λ$, Moerdijk-Weiss dendroidal category $Ω$, and categories similar to graphical categories of Hackney-Robertson-Yau are twisted arrow categories of symmetric or cyclic operads. Twisted arrow categories of operads admit Segal presheaves and 2-Segal presheaves, or decomposition spaces. Twisted arrow category of an operad $P$ is the $(\infty, 1)$-localization of the corresponding category $Ω/P$ by the boundary preserving morphisms. Under mild assumptions, twisted arrow categories of operads, and closely related universal enveloping categories, are generalized Reedy. We also introduce twisted arrow operads, which are related to Baez--Dolan plus construction.

description: Gamma-ray data from the Fermi-Large Area Telescope reveal an unexplained, apparently diffuse, signal from the Galactic bulge that peaks near 2 GeV with an approximately spherical intensity profile $\propto r^{-2.4}$ that extends to angular radial scales of at least 10 degrees, possibly to 20 degrees. The origin of this "Galactic Centre Excess" (GCE) has been debated with proposed sources prominently including self-annihilating dark matter and a hitherto undetected population of millisecond pulsars (MSPs). However, the conventional channel for the generation of MSPs has been found to predict too many low mass X-ray binary (LMXB) systems and, because of the expected large natal kicks, may not accommodate the close spatial correspondence between the GCE signal and stars in the bulge. Here we report a binary population synthesis forward model that demonstrates that an MSP population arising from the accretion induced collapse (AIC) of O-Ne white dwarfs in Galactic bulge binaries can naturally reproduce the morphology, spectral shape, and intensity of the GCE signal while also obeying LMXB constraints. Synchrotron emission from MSP-launched cosmic ray electrons and positrons may simultaneously explain the mysterious, microwave "haze" from the inner Galaxy

description: The Open PHACTS Discovery Platform brings together vast amounts of linked data in a single integrated, open infrastructure providing a platform for researchers to access and query publicly-available pharmacological data. The platform integrates major open data sources (e.g. ChEMBL, UniProt, WikiPathways, SureChEMBL, DrugBank, Disgenet and their associated Chemistry) on compounds, patents, diseases, targets and pathways; linked by identifiers, semantic and structural chemistry information, re-exposed as a collection of unified web APIs, workflow components plus tool integrations. The platform is maintained by the Open PHACTS Foundation, which is supported by members from biopharmaceutical industry and Research Organisations with an active developer and user community. BioExcel is an European Centre of Excellence that support academia and industry in the use of high-end computing in biomolecular research. Part of BioExcel’s roadmap for workflows is to develop Workflow Blocks for biomolecular simulation and modelling, which includes Open PHACTS as a data service. Such blocks, including the Open PHACTS platform, can be deployed in private or public cloud environments, and used to build portable pipelines. BioExcel is currently developing a series of pilot use cases, including a Virtual Screening workflow using Open PHACTS. In this webinar, Nick Lynch (Open PHACTS Foundation), Stian Soiland-Reyes (The University of Manchester) and Adam Hospital (IRB Barcelona) will present the Open PHACTS platform and how it will be used with BioExcel workflow blocks to build a virtual screening pipeline.

description: Mean-variance portfolio decisions that combine prediction and optimisation have been shown to have poor empirical performance. Here, we consider the performance of various shrinkage methods by their efficient frontiers under different distributional assumptions to study the impact of reasonable departures from Normality. Namely, we investigate the impact of first-order auto-correlation, second-order auto-correlation, skewness, and excess kurtosis. We show that the shrinkage methods tend to re-scale the sample efficient frontier, which can change based on the nature of local perturbations from Normality. This re-scaling implies that the standard approach of comparing decision rules for a fixed level of risk aversion is problematic, and more so in a dynamic market setting. Our results suggest that comparing efficient frontiers has serious implications which oppose the prevailing thinking in the literature. Namely, that sample estimators out-perform Stein type estimators of the mean, and that improving the prediction of the covariance has greater importance than improving that of the means.

description: The impact of climate change on herbivorous insects can have far-reaching
consequences for ecosystem processes. However, experiments investigating the
combined effects of multiple climate change drivers on herbivorous insects are
scarce. We independently manipulated three climate change drivers (CO2,
warming, drought) in a Danish heathland ecosystem. The experiment was
established in 2005 as a full factorial split-plot with 6 blocks 9 2 levels of
CO2 9 2 levels of warming 9 2 levels of drought = 48 plots. In 2008, we
exposed 432 larvae (n = 9 per plot) of the heather beetle (Lochmaea suturalis
THOMSON), an important herbivore on heather, to ambient versus elevated
drought, temperature, and CO2 (plus all combinations) for 5 weeks. Larval
weight and survival were highest under ambient conditions and decreased
significantly with the number of climate change drivers. Weight was lowest
under the drought treatment, and there was a three-way interaction between
time, CO2, and drought. Survival was lowest when drought, warming, and elevated
CO2 were combined. Effects of climate change drivers depended on other
co-acting factors and were mediated by changes in plant secondary compounds,
nitrogen, and water content. Overall, drought was the most important factor
for this insect herbivore. Our study shows that weight and survival of insect
herbivores may decline under future climate. The complexity of insect herbivore
responses increases with the number of combined climate change drivers.

description: The reaction coordinate describing a transition between reactant and product is a fundamental concept in the theory of chemical reactions. Within transition-path theory, a quantitative definition of the reaction coordinate is found in the committor, which is the probability that a trajectory initiated from a given microstate first reaches the product before the reactant. Here we develop an information-theoretic origin for the committor and show how selecting transition paths from the equilibrium ensemble induces entropy production which exactly equals the information that system dynamics provide about the reactivity of trajectories. This equality of entropy production and dynamical information generation also holds at the level of arbitrary individual coordinates, providing parallel measures of the coordinate's relevance to the reaction, each of which is maximized by the committor.

description: Structural features are important features in a geometrical graph. Although there are some correlation analysis of features based on covariance, there is no relevant research on structural feature correlation analysis with graph neural networks. In this paper, we introuduce graph feature to feature (Fea2Fea) prediction pipelines in a low dimensional space to explore some preliminary results on structural feature correlation, which is based on graph neural network. The results show that there exists high correlation between some of the structural features. An irredundant feature combination with initial node features, which is filtered by graph neural network has improved its classification accuracy in some graph-based tasks. We compare differences between concatenation methods on connecting embeddings between features and show that the simplest is the best. We generalize on the synthetic geometric graphs and certify the results on prediction difficulty between structural features.

description: New optical sensors with a segmented photosensitive area are being developed for the next generation of neutrino telescopes at the South Pole. In addition to increasing sensitivity to high-energy astrophysical neutrinos, we show that this will also lead to a significant improvement in sensitivity to MeV neutrinos, such as those produced in core-collapse supernovae (CCSN). These low-energy neutrinos can provide a detailed picture of the events after stellar core collapse, testing our understanding of these violent explosions. We present studies on the event-based detection of MeV neutrinos with a segmented sensor and, for the first time, the potential of a corresponding detector in the deep ice at the South Pole for the detection of extra-galactic CCSN. We find that exploiting temporal coincidences between signals in different photocathode segments, a $27\ \mathrm{M}_{\odot}$ progenitor mass CCSN can be detected up to a distance of 269 kpc with a false detection rate of $0.01$ year$^{-1}$ with a detector consisting of 10000 sensors. Increasing the number of sensors to 20000 and reducing the optical background by a factor of 140 expands the range such that a CCSN detection rate of $0.08$ per year is achieved, while keeping the false detection rate at $0.01$ year$^{-1}$.

description: Cognitive radio networks (CRNs) and millimeter wave (mmWave) communications are two major technologies to enhance the spectrum efficiency (SE). Considering that the SE improvement in the CRNs is limited due to the interference temperature imposed on the primary user (PU), and the severe path loss and high directivity in mmWave communications make it vulnerable to blockage events, we introduce an intelligent reflecting surface (IRS) into mmWave CRNs. Due to the estimation mismatch and the passivity of Eavesdroppers (Eves), perfect channel state information (CSI) of wiretap links is challenging to obtain, which promotes our research on robust secure beamforming (BF) design in the IRS-assisted mmWave CRNs. This paper considers the collaborate scenario of Eves, which allows us to investigate the BF design in the harsh eavesdropping environment. Specifically, by using a uniform linear array (ULA) at the cognitive base station (CBS) and a uniform planar array (UPA) at the IRS, and supposing that imperfect CSIs of angle-of-departures for wiretap links are known, we formulate a constrained problem to maximize the worst-case achievable secrecy rate (ASR) of the secondary user (SU) by jointly designing the transmit BF at the CBS and reflect BF at the IRS. To solve the non-convex problem with coupled variables, an efficient alternating optimization algorithm is proposed. Finally, simulation results indicate that the ASR performance of our proposed algorithm has a small gap with that of the optimal solution with perfect CSI compared with the other benchmarks.

description: O caleidoscópio missionário analisa as alianças, conflitos e interesses na rede de atores constituída pela atuação de agências missionárias evangélicas junto aos povos indígenas da Terra Indígena Vale do Javari, no município de Atalaia do Norte, Amazonas. A partir da abordagem metodológica da teoria de Ator Rede (TAR), discuto as relações estabelecidas entre os atores nos anos 2014 - 2020. A atuação missionária desdobrou-se no Javari em três ondas. A primeira, na metade do século XX, foi um período de encontros e contato entre indígenas e missionários vindos dos Estados Unidos no interior da terra indígena. A segunda teve início na década 1990 e se caracterizou principalmente pelos convênios e projetos estabelecidos entre movimento indígena, Estado e agências missionárias. A terceira onda é voltada ao trabalho missionário no município de Atalaia do Norte, desta vez com a presença de missionários nacionais, internacionais e inclusive indígenas. Desde a década de 1950, as agências missionárias evangélicas de origem norte-americana com sede no Brasil procuram ‘levar palavra de Deus’, ‘alcançar todos os povos’ e ‘plantar igrejas’, tendo como principal estratégia a tradução da Bíblia nas línguas indígenas e projetos de cunho assistencial, com reiteradas tentativas de contato com povos em situação de isolamento.

description: Mario Minoja e Silvana Signori con riferimento ai temi del Manifesto L’impresa che vogliamo” sottolineano come la funzione civile sia nel DNA dell’Economia aziendale perché ha una forte componente umanistica, perché si occupa di aziende che sono fatte di persone e sono fatte per le persone, perché si sviluppa nel solco della tradizione e della Scuola italiana che sin dall’inizio ha riconosciuto il ruolo sociale dell’impresa.
