description: Visual object recognition has been extensively studied in both neuroscience and computer vision. Recently, the most popular class of artificial systems for this task, deep convolutional neural networks (CNNs), has been shown to provide excellent models for its functional analogue in the brain, the ventral stream in visual cortex. This has prompted questions on what, if any, are the common principles underlying the reformatting of visual information as it flows through a CNN or the ventral stream. Here we consider some prominent statistical patterns that are known to exist in the internal representations of either CNNs or the visual cortex and look for them in the other system. We show that intrinsic dimensionality (ID) of object representations along the rat homologue of the ventral stream presents two distinct expansion-contraction phases, as previously shown for CNNs. Conversely, in CNNs, we show that training results in both distillation and active pruning (mirroring the increase in ID) of low- to middle-level image information in single units, as representations gain the ability to support invariant discrimination, in agreement with previous observations in rat visual cortex. Taken together, our findings suggest that CNNs and visual cortex share a similarly tight relationship between dimensionality expansion/reduction of object representations and reformatting of image information.

description: It has been known that sharp Sobolev embeddings into weak Lebesgue spaces are non-compact but the question of whether the measure of non-compactness of such an embedding equals to its operator norm constituted a well-known open problem. The existing theory suggested an argument that would possibly solve the problem should the target norms be disjointly superadditive, but the question of disjoint superadditivity of spaces $L^{p,\infty}$ has been open, too. In this paper, we solve both these problems. We first show that weak Lebesgue spaces are never disjointly superadditive, so the suggested technique is ruled out. But then we show that, perhaps somewhat surprisingly, the measure of non-compactness of a sharp Sobolev embedding coincides with the embedding norm nevertheless, at least as long as $p<\infty$. Finally, we show that if the target space is $L^{\infty}$ (which formally is also a weak Lebesgue space with $p=\infty$), then the things are essentially different. To give a comprehensive answer including this case, too, we develop a new method based on a rather unexpected combinatorial argument and prove thereby a general principle, whose special case implies that the measure of non-compactness, in this case, is strictly less than its norm. We develop a technique that enables us to evaluate this measure of non-compactness exactly.

description: This work presents Direct Numerical Simulations of capillary wave turbulence solving the full 3D Navier Stokes equations of a two-phase flow. When the interface is locally forced at large scales, a statistical stationary state appears after few forcing periods. Smaller wave scales are generated by nonlinear interactions, and the wave height spectrum is found to obey a power law in both wave number and frequency in good agreement with weak turbulence theory. By estimating the mean energy flux from the dissipated power, the Kolmogorov-Zakharov constant is evaluated and found to be compatible with the exact theoretical value. The time scale separation between linear, nonlinear interaction and dissipative times is also observed. These numerical results confirm the validity of weak turbulence approach to quantify out-of equilibrium wave statistics.

description: The aim of the thesis was to study the ecclesiastical administration and geography of Lesvos during the 19th century and until the liberation of the island. We first examined the geography of the island of Lesvos, while we also dealt with the division of Lesvos into two provinces, that of the metropolis of Mytilene and that of the metropolis of Mithimni, including all the necessary information about them. Subsequently, we referred to the patriarchal monasteries of the island and their metochia, as well as to other monasteries per Metropolis from the 19th century until 1912, the date of the liberation of the island, while we also referred to the Metropolitans who served in each of the two metropolises of the island. Another objective of the work was to examine the historical context of the church administration and geography of the island from the 19th century until 1912.

description: A phytochemical study of the methanol extract of the fruit of Maesa lanceolata resulted in the isolation of a new alkenylbenzoquinone (1), alongside the known compounds (Z)-2,5-dihydroxy-6-methyl-3-(pentadec-10’-enyl)-1,4-benzoquinone (2), 2,5-dihydroxy-6-methyl-3-(nonadec-14’-enyl)-1,4-benzoquinone (3), 2,5-dihydroxy-6-methyl-3-(tridecyl)-1,4-benzoquinone (4), (2S,3S,4R,2’R,9E)-[2’-hydroxytetraeicosanoyl]-2-aminooctadec-9-ene-1,3,4-triol (5), monopalmitin (glyceryl palmitate) (6), lupeol (7), and 3-O-(β-D-glucopyranoside)-β-sitosterol (8). The structures of the compounds were established by the means of spectroscopic (1 D- and 2 D-NMR) and spectrometric techniques (MS). The isolated compounds were assessed for their antibacterial, cytotoxic, and antiradical activities. Compound 2 showed moderate activity against Staphylococcus warneri (DSMZ 20036), while the other compounds were inactive. The two quinones 1 and 2 were significantly cytotoxic, with IC50 values of 0.005 µM and 12.5 µM respectively, and were weakly active towards DPPH radical (IC50 >250 µg/mL).

description: We analyze a system composed of a superconducting flux qubit coupled to a transmission-line resonator driven by two signals with frequencies close to the resonator's harmonics. The first strong signal is used for exciting the system to a high energetic state while a second weak signal is applied for probing effective eigenstates of the system. In the framework of doubly dressed states we showed the possibility of amplification and attenuation of the probe signal by direct transitions at the Rabi frequency. We present a brief review of theoretical and experimental works where a direct resonance at Rabi frequency have been investigated in superconducting flux qubits. The interaction of the qubit with photons of two harmonics has prospects to be used as a quantum amplifier (microwave laser) or an attenuator.

description: Die Anzahl der Menschen, welche sich psychisch stark belastet fühlen, steigt kontinuierlich an. Angesichts der Handlungsfelder der Sozialen Arbeit ist anzunehmen, dass Fachkräfte regelmässig mit Menschen mit psychischer Störung in Kontakt kommen. Zum einen haben diese Menschen mit den Symptomen der psychischen Störung und zum anderen mit der (Selbst-) Stigmatisierung zu kämpfen. Diese doppelte Last bringt persönliche sowie gesellschaftliche Nachteile mit sich. Aufgrund dessen haben sich Joel Kaufmann und Lara Bachmann entschieden, sich mit der Frage auseinanderzusetzen, wie Selbststigmatisierung frühzeitig erkannt und daraufhin interveniert werden kann. Zur Beantwortung gibt es diese Arbeit mit dem Titel «Früherkennung der Selbststigmatisierung bei Menschen mit psychischer Störung». Diese doppelte Last bringt persönliche sowie gesellschaftliche Nachteile mit sich.

Durch verschiedene konsultierte Quellen sowie gewonnene Information aus einem Interview mit einer schizophreniebetroffenen Person wurde deutlich, dass die soziale Teilhabe bei selbststigmatisierenden Menschen beeinträchtigt sein kann. Insbesondere ist hierbei das Thema «Scham» hervorzuheben. Um den Selbststigmatisierungsprozess zu erkennen und daraufhin zu intervenieren, braucht es nicht nur Fachpersonen, sondern bedingt eine starke Netzwerkarbeit. Der Ansatz der Früherkennung und Frühintervention vom Bundesamt für Gesundheit ist ein wesentlicher Bestandteil dieser Arbeit. Entlang dieses Ansatzes wurden Handlungsoptionen für die Fachpersonen der Sozialen Arbeit herausgearbeitet, um so den Grundsätzen der Menschenwürde, der Menschenrechte und der sozialen Gerechtigkeit nachzukommen.

description: We study a resource allocation setting where $m$ discrete items are to be divided among $n$ agents with additive utilities, and the agents' utilities for individual items are drawn at random from a probability distribution. Since common fairness notions like envy-freeness and proportionality cannot always be satisfied in this setting, an important question is when allocations satisfying these notions exist. In this paper, we close several gaps in the line of work on asymptotic fair division. First, we prove that the classical round-robin algorithm is likely to produce an envy-free allocation provided that $m=Ω(n\log n/\log\log n)$, matching the lower bound from prior work. We then show that a proportional allocation exists with high probability as long as $m\geq n$, while an allocation satisfying envy-freeness up to any item (EFX) is likely to be present for any relation between $m$ and $n$. Finally, we consider a related setting where each agent is assigned exactly one item and the remaining items are left unassigned, and show that the transition from non-existence to existence with respect to envy-free assignments occurs at $m=en$.

description: Knowledge on nuclear cluster physics has increased considerably as nuclear clustering remains one of the most fruitful domains of nuclear physics, facing some of the greatest challenges and opportunities in the years ahead. The occurrence of "exotic" shapes in light N=Z alpha-like nuclei and the evolution of clustering from stability to the drip-lines are being investigated more and more accurately both theoretically and experimentally. Experimental progresses in understanding these questions were recently examined and will be further revisited in this introductory talk: clustering aspects are, in particular, discussed for light exotic nuclei with a large neutron excess such as neutron-rich Oxygen isotopes with their complete spectrocopy.

description: Recent studies demonstrated that saikosaponin (SS) A and other SSs extracted from Bupleurum falcatum L. (Apiaceae) roots abolished different behaviours motivated by drugs of abuse and palatable foods in rats. The present study was designed to investigate the effect of an SS-enriched extract fraction of B. falcatum roots on operant, oral self-administration of alcohol and chocolate in rats. To this end, female Sardinian alcohol-preferring and Wistar rats were trained to lever-respond for alcohol (15% v/v) and chocolate (5% w/v powdered Nesquik in water), respectively. Acute treatment with B. falcatum extract (0, 0.75, 1.5, and 3 mg/kg, i.p.) reduced, in a dose-related manner, both alcohol and chocolate self-administration. These data confirm the notion that B. falcatum extracts may be a valuable source of pharmacological agents with anti-addictive and anorectic potential. The use of experimental procedures with predictive validity for the human disease adds strength to the translational potential of these results.

description: We consider the problem of minimizing a high-dimensional objective function, which may include a regularization term, using (possibly noisy) evaluations of the function. Such optimization is also called derivative-free, zeroth-order, or black-box optimization. We propose a new $\textbf{Z}$eroth-$\textbf{O}$rder $\textbf{R}$egularized $\textbf{O}$ptimization method, dubbed ZORO. When the underlying gradient is approximately sparse at an iterate, ZORO needs very few objective function evaluations to obtain a new iterate that decreases the objective function. We achieve this with an adaptive, randomized gradient estimator, followed by an inexact proximal-gradient scheme. Under a novel approximately sparse gradient assumption and various different convex settings, we show the (theoretical and empirical) convergence rate of ZORO is only logarithmically dependent on the problem dimension. Numerical experiments show that ZORO outperforms the existing methods with similar assumptions, on both synthetic and real datasets.

This is made using the efficient computational method of generating functional. Also, the method is used for the spectral characterization of homogeneous harmonic oscillator confinement, found as a particular case of pseudo-Gaussian oscillator confinement. Finally the aspect of confinement with an impenetrable sphere of finite radius is considered by studying its conjugate effect along with harmonic oscillator upon the atom.

Publisher: name: Bank of Canada
Year: 2022

description: Are unregulated capital flows excessive during a stagflation episode? We argue that they likely
are, owing to a macroeconomic externality operating through the economy’s supply side.
Inflows raise domestic wages through a wealth effect on labor supply and cause unwelcome
upward pressure on marginal costs in countries where monetary policy is trying to drive down
costs to stabilize inflation. Yet market forces are likely to generate such inflows. Optimal capital
flow management instead requires net outflows, suggesting topsy-turvy capital flows following
markup shocks.
description: Les flux de capitaux non réglementés sont-ils trop élevés en période de stagflation? Nous
soutenons qu’ils le sont probablement, en raison d’une externalité macroéconomique qui agit
par le canal de l’offre dans l’économie. Les entrées de capitaux font augmenter les salaires
intérieurs par l’entremise d’un effet de richesse sur l’offre de travail. Elles exercent aussi des
pressions à la hausse indésirables sur les coûts marginaux dans les pays où la politique
monétaire tente de faire baisser les coûts pour stabiliser l’inflation. Pourtant, les forces du
marché sont susceptibles de causer de telles entrées de capitaux. Or une gestion optimale des
flux de capitaux viserait plutôt des sorties nettes de capitaux. Cela fait craindre des flux de
capitaux à l’envers à la suite de chocs de taux de marge.

description: The amount of absorbed energy in the keyhole as well as its spatial and temporal distribution is essential to model the laser beam welding process. The recoil pressure, which develops because of the evaporation process induced by the absorbed laser energy at the keyhole wall, is a key determining factor for the macroscopic flow of the molten metal in the weld pool during high-power laser beam welding. Consequently, a realistic implementation of the effect of laser radiation on the weld metal is crucial to obtain reliable and accurate simulation results. In this paper, we discuss manyfold different improvements on the laser-material interaction, namely, the ray tracing method, in the numerical simulation of the laser beam welding process. The first improvement relates to locating the exact reflection points in the ray tracing method using a so-called cosine condition in the determination algorithm for the intersection of reflected rays and the keyhole surface. A second correction refers to the numerical treatment of the Gaussian distribution of the laser beam, whose beam width is defined by a decay of the laser intensity by a factor of 1/e2, thus ignoring around 14% of the total laser beam energy. In the third step, the changes in the laser radiation distribution in the vertical direction were adapted by using different approximations for the converging and the diverging regions of the laser beam, thus mimicking the beam caustic. Finally, a virtual mesh refinement was adopted in the ray tracing routine. The obtained numerical results were validated with experimental measurements.

description: A continuous transition from early Friedmann-like radiation era through to late time cosmic acceleration passing through a long Friedmann-like matter dominated era followed by a second phase of radiation era has been realized in modified theory of gravity containing a combination of curvature squared term, a linear term, a three-half term and an ideal fluid. Thus the history of cosmic evolution is explained by modified theory of gravity singlehandedly. The second phase of radiation-like era might provide an explanation to the hydrogen and helium reionization at low redshift.

description: In the Olive drupe (Olea europaea L.) oil extraction process, 80% of the volume generated is waste (bagasse). Advancing the expansion of the olive oil market, it is necessary to develop alternatives that, in addition to adding value to industrial waste, also reduce possible environmental damage. Our study aimed to understand the antimicrobial and Cytotoxic activity potential of the residues from the extraction of olive oil from the blend of the varieties Arbequina and Arbosana. The extract shows cytotoxic activity, inhibiting about 75% of cancer cells in the human colon at a concentration of 0.15 mg of Gallic Acid equivalent (GAE)/mL. The effectiveness of the extract against microorganisms often associated with foodborne diseases and food decomposition has also been discovered, without compromising the microorganisms responsible for fermentation. Thus, this study provides future perspectives for the use of active ingredients extracted from the residue from the extraction of olive oil.

description: The resonant quantum dynamics of an excited two-level emitter is investigated via classical modulation of its transition frequency while simultaneously the radiator interacts with a broadband electromagnetic field reservoir. The frequency of modulation is selected to be of the order of the bare-state spontaneous decay rate. In this way, one can induce quantum interference effects and, consequently, quantum coherences among multiple decaying transition pathways. Depending on the modulation depth and its absolute phase, both the spontaneous emission and the frequency shift may be conveniently modified and controlled.

description: Origanum vulgare, known for its medicinal value, is officially accepted in many countries. The flowers and leaves are used globally in homeopathy. In Brazilian folk medicine, O. vulgare has been used to treat diabetes mellitus. This study evaluated the hypoglycemic activity of an infusion extract (RosCE) of commercially available O. vulgare leaves in alloxan-induced diabetic rats. Oral administration of RosCE resulted in the reduction of blood glucose levels after the first day of treatment, compared to the diabetic control group. These results showed that RosCE displays hypoglycemic activity, which may be due to the combined effect of rosmarinic acid, and other minor compounds. Reversed phase-high performance liquid chromatography-diode array detection was used to identify and quantify the major constituents of RosCE. This study presents evidence that supports the folkloric use of O. vulgare for the treatment of hyperglycemia, confirming the use of its infusion as an antidiabetic herbal medicine.
Gravitational collapse of a fluid with torsion into a universe in a black hole

description: We consider gravitational collapse of a spherically symmetric sphere of a fluid with spin and torsion into a black hole. We use the Tolman metric and the Einstein--Cartan field equations with a relativistic spin fluid as a source. We show that gravitational repulsion of torsion prevents a singularity and replaces it with a nonsingular bounce. Quantum particle production during contraction helps torsion to dominate over shear. Particle production during expansion can generate a finite period of inflation and produce enormous amounts of matter. The resulting closed universe on the other side of the event horizon may have several bounces. Such a universe is oscillatory, with each cycle larger in size then the previous cycle, until it reaches the cosmological size and expands indefinitely. Our universe might have therefore originated from a black hole.

description: Didymella glomerata and Truncatella angustata associated with grapevine trunk diseases (GTDs) in Iran, were grown in vitro to evaluate the production of phytotoxic metabolites as potential pathogenicity determinants. 2,5-Dihydroxymethylfuran and (+)-6-hydroxyramulosin were isolated from the culture filtrates of D. glomerata and T. angustata, respectively. They were identified by physical and spectroscopic (essentially 1 D and 2 D 1H and 13C NMR and ESIMS) methods and X ray analysis. Both compounds induced significant necrosis and curling on the leaves of the host plant Vitis vinifera L. and the effects were concentration dependent. No effect was observed on the leaves of the non-host Solanum lycopersicum L.. plant.

description: Background Healthcare organisations, such as hospitals, are largely seen as task-oriented, width different people expected to work in interdependent teams. The objective of this study was to investigate the relevance of individual factors (job satisfaction) and individual competences (emotional competence) for organisational commitment in a sample of healthcare professionals. Methods A cross-sectional survey was conducted among 96 healthcare professionals from March to June 2018 in the catchment area of five clinics in Bavaria, Germany. The present research examined the moderating role of emotional competence on the relationship between job satisfaction and organisational commitment using moderated regression analysis and simple slope analysis. Results Multiple regression analysis indicated that emotional competence moderated the relationship between satisfaction with the job and commitment to the job. The results showed that healthcare professionals with high emotional competence are able to deal more effectively with dissatisfaction in the workplace so that organisational commitment remains unaffected. Conclusions Based on the findings of this study emotional competence of healthcare professionals is important for increasing job satisfaction and commitment to the job. Especially for healthcare professionals whose job satisfaction is low, a high level of emotional competence enables them to maintain a high level of organisational commitment. The findings of the study are discussed at the theoretical level for researchers and practical level for hospital managers interested in fostering emotional competence and improving healthcare professionals’ job satisfaction and their organisational commitment, which ultimately may lead to effective performance.

description: The algebraic expression $3 + 2 + 6$ can be evaluated to $11$, but it can also be partially evaluated to $5 + 6$. In categorical algebra, such partial evaluations can be defined in terms of the $1$-skeleton of the bar construction for algebras of a monad. We show that this partial evaluation relation can be seen as the relation internal to the category of algebras generated by relating a formal expression to its total evaluation. The relation is transitive for many monads which describe commonly encountered algebraic structures, and more generally for BC monads on $\mathsf{Set}$ (which are those monads for which the underlying functor and the multiplication are weakly cartesian). We find that this is not true for all monads: we describe a finitary monad on $\mathsf{Set}$ for which the partial evaluation relation on the terminal algebra is not transitive. With the perspective of higher algebraic rewriting in mind, we then investigate the compositional structure of the bar construction in all dimensions. We show that for algebras of BC monads, the bar construction has fillers for all directed acyclic configurations in $Δ^n$, but generally not all inner horns.

description: Chenopodin is an 11S-type globulin purified from Chenopodium quinoa seeds, which can bind carbohydrates and hemagglutinating human erythrocytes. The present study aimed to evaluate the N-terminal structure of the heterodimeric Chenopodin and its effects in models of inflammation. Chenopodin presented two subunits on its structure and has N-terminal homology with other Chenopodin in 92%. Chenopodin decreased paw edema and neutrophil recruitment induced by carrageenan in mice. Concluding, we demonstrated that Chenopodin exhibits in vivo anti-inflammatory activity.
Finding Supercharacter Theories on Character Tables

description: We describe an easy way how to find supercharacter theories for a finite group, if its character table is known. Namely, we show how an arbitrary partition of the conjugacy classes or of the irreducible characters can be refined to the coarsest partition that belongs to a supercharacter theory. Our constructions emphasize the duality between superclasses and supercharacters. An algorithm is presented to find all supercharacter theories on a given character table. The algorithm is used to compute the number of supercharacter theories for some nonabelian simple groups with up to 26 conjugacy classes.

description: This thesis examines the motivations of Central American Unionists and the failure of their movement in the early years of the twentieth century. The existing literature attributes the failure of Central American unification during this era to U.S. policies meant to maintain a divided isthmus in order to economically and politically exploit the region. A closer analysis of the primary sources, however, reveals that union failed because of internal factors, and that Washington's actions generally favored efforts to rejoin the nations to reduce isthmian tensions. Attempts to reunite the republics failed because of regional and domestic political rivalries, weaknesses in the institutions created to effect union, and nearly insurmountable geographic barriers.
