description: We consider the problem of optimizing the steady state of a dynamical system in closed loop. Conventionally, the design of feedback optimization control laws assumes that the system is stationary. However, in reality, the dynamics of the (slow) iterative optimization routines can interfere with the (fast) system dynamics. We provide a study of the stability and convergence of these feedback optimization setups in closed loop with the underlying plant, via a custom-tailored singular perturbation analysis result. Our study is particularly geared towards applications in power systems and the question whether recently developed online optimization schemes can be deployed without jeopardizing dynamic system stability.

description: Atmospheric nitrogen may be a necessary ingredient for the habitability of a planet since its presence helps to prevent water loss from a planet. The present day nitrogen isotopic ratio, $^{15}$N/$^{14}$N, in the Earth's atmosphere is a combination of the primitive Earth's ratio and the ratio that might have been delivered in comets and asteroids. Asteroids have a nitrogen isotopic ratio that is close to the Earth's. This indicates either a similar formation environment to the Earth or that the main source of nitrogen was delivery by asteroids. However, according to geological records, the Earth's atmosphere could have been enriched in $^{15}$N during the Archean era. Comets have higher a $^{15}$N/$^{14}$N ratio than the current atmosphere of the Earth and we find that about $5\%$ $\sim$ $10\%$ of nitrogen in the atmosphere of the Earth may have been delivered by comets to explain the current Earth's atmosphere or the enriched $^{15}$N Earth's atmosphere. We model the evolution of the radii of the snow lines of molecular nitrogen and ammonia in a protoplanetary disk and find that both have radii that put them farther from the Sun than the main asteroid belt. With an analytic secular resonance model and N--body simulations we find that the $ν_8$ apsidal precession secular resonance with Neptune, which is located in the Kuiper belt, is a likely origin for the nitrogen-delivering comets that impact the Earth.

description: Supplementation with Angiotensin-(1-7) [(Ang-1-7)] has received considerable attention due to its possible ergogenic effects on physical performance. The effects of a single dose of Ang-(1-7) on the performance of mountain bike (MTB) athletes during progressive load tests performed until the onset of voluntary fatigue have previously been demonstrated. This study tested the effects of Ang-(1-7) in two different exercise protocols with different metabolic demands: aerobic (time trial) and anaerobic (repeated sprint). Twenty one male recreational athletes were given capsules containing an oral formulation of HPβCD-Ang-(1-7) (0.8 mg) and HPβCD-placebo (only HPβCD) over a 7-day interval; a double-blind randomized crossover design was used. Physical performance was examined using two protocols: a 20-km cycling time trial or 4 × 30-s repeated all-out sprints on a leg cycle ergometer. Data were collected before and after physical tests to assess fatigue parameters, and included lactate levels, and muscle activation during the sprint protocol as evaluated by electromyography (EMG); cardiovascular parameters: diastolic and systolic blood pressure and heart rate; and performance parameters, time to complete (time trial), maximum power and mean power (repeated sprint). Supplementation with an oral formulation of HPβCD-Ang-(1-7) reduced basal plasma lactate levels and promoted the maintenance of plasma glucose levels after repeated sprints. Supplementation with HPβCD-Ang-(1-7) also increased baseline plasma nitrite levels and reduced resting diastolic blood pressure in a time trial protocol. HPβCD-Ang-(1-7) had no effect on the time trial or repeat sprint performance, or on the EMG recordings of the vastus lateralis and vastus medialis. Supplementation with HPβCD-Ang-(1-7) did not improve physical performance in time trial or in repeated sprints; however, it promoted the maintenance of plasma glucose and lactate levels after the sprint protocol and at rest, respectively. In addition, HPβCD-Ang-(1-7) also increased resting plasma nitrite levels and reduced diastolic blood pressure in the time trial protocol. RBR-2nbmpbc, registered January 6th, 2023.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: This paper presents the proof-of-concept of the first automatic voice assistant ever built in Wolof language, the main vehicular language spoken in Senegal. This voicebot is the result of a collaborative research project between Orange Innovation in France, Orange Senegal (aka Sonatel) and ADNCorp, a small IT company based in Dakar, Senegal. The purpose of the voicebot is to provide information to Orange customers about the Sargal loyalty program of Orange Senegal by using the most natural mean to communicate: speech. The voicebot receives in input the customer's oral request that is then processed by a SLU system to reply to the customer's request using audio recordings. The first results of this proof-of-concept are encouraging as we achieved 22\% of WER for the ASR task and 78\% of F1-score on the NLU task.

description: We use the optimal fluctuation method to find the density of electron states inside the pseudogap in disordered Peierls chains. The electrons are described by the one-dimensional Dirac Hamiltonian with randomly varying mass (the Fluctuating Gap Model). We establish a relation between the disorder average in this model and the quantum-mechanical average for a certain double-well problem. We show that the optimal disorder fluctuation, which has the form of a soliton-antisoliton pair, corresponds to the instanton trajectory in the double-well problem. We use the instanton method developed for the double-well problem to find the contribution to the density of states from disorder realizations close to the optimal fluctuation.

description: Evaluating new technological developments for energy systems is becoming more and more complex. The overall application environment is a continuously growing and interconnected cyber-physical system so that analytical assessment is practically impossible to realize. Consequently, new solutions must be evaluated in simulation studies. Due to the interdisciplinarity of the simulation scenarios, various heterogeneous tools must be connected. This approach is known as co-simulation. During the last years, different approaches have been developed or adapted for applications in energy systems. In this paper, two co-simulation approaches are compared that follow generic, versatile concepts. The tool mosaik, which has been explicitly developed for the purpose of co-simulation in complex energy systems, is compared to the High Level Architecture (HLA), which possesses a domain-independent scope but is often employed in the energy domain. The comparison is twofold, considering the tools' conceptual architectures as well as results from the simulation of representative test cases. It suggests that mosaik may be the better choice for entry-level, prototypical co-simulation while HLA is more suited for complex and extensive studies.
Phase Distribution in a Disordered Chain and the Emergence of a Two-parameter Scaling in the Quasi-ballistic to the Mildly Localized Regime

description: We study the phase distribution of the complex reflection coefficient in different configurations as a disordered 1D system evolves in length, and its effect on the distribution of the 4-probe resistance $R_4$. The stationary ($L \to \infty$) phase distribution is almost always strongly non-uniform and is in general double-peaked with their separation decaying algebraically with growing disorder strength to finally give rise to a single narrow peak at infinitely strong disorder. Further in the length regime where the phase distribution still evolves with length (i.e., in the quasi-ballistic to the mildly localized regime), the phase distribution affects the distribution of the resistance in such a way as to make the mean and the variance of $log(1+R_4)$ diverge independently with length with different exponents. As $L \to \infty$, these two exponents become identical (unity). Obviously, these facts imply two relevant parameters for scaling in the quasi-ballistic to the mildly localized regime finally crossing over to one-parameter scaling in the strongly localized regime.

description: Function-as-a-Service (FaaS) is a recent and already very popular paradigm in cloud computing. The function provider need only specify the function to be run, usually in a high-level language like JavaScript, and the service provider orchestrates all the necessary infrastructure and software stacks. The function provider is only billed for the actual computational resources used by the function invocation. Compared to previous cloud paradigms, FaaS requires significantly more fine-grained resource measurement mechanisms, e.g. to measure compute time and memory usage of a single function invocation with sub-second accuracy. Thanks to the short duration and stateless nature of functions, and the availability of multiple open-source frameworks, FaaS enables non-traditional service providers e.g. individuals or data centers with spare capacity. However, this exacerbates the challenge of ensuring that resource consumption is measured accurately and reported reliably. It also raises the issues of ensuring computation is done correctly and minimizing the amount of information leaked to service providers. To address these challenges, we introduce S-FaaS, the first architecture and implementation of FaaS to provide strong security and accountability guarantees backed by Intel SGX. To match the dynamic event-driven nature of FaaS, our design introduces a new key distribution enclave and a novel transitive attestation protocol. A core contribution of S-FaaS is our set of resource measurement mechanisms that securely measure compute time inside an enclave, and actual memory allocations. We have integrated S-FaaS into the popular OpenWhisk FaaS framework. We evaluate the security of our architecture, the accuracy of our resource measurement mechanisms, and the performance of our implementation, showing that our resource measurement mechanisms add less than 6.3% latency on standardized benchmarks.
Gravitational reaction force on a particle in the Schwarzschild background

description: We formulate a new method to calculate the gravitational reaction force on a particle of mass $μ$ orbiting a massive black hole of mass $M$. In this formalism, the tail part of the retarded Green function, which is responsible for the reaction force, is calculated at the level of the Teukolsky equation. Our method naturally allows a systematic post-Minkowskian (PM) expansion of the tail part at short distances. As a first step, we consider the case of a Schwarzschild black hole and explicitly calculate the first post-Newtonian (1PN) tail part of the Green function. There are, however, a couple of issues to be resolved before explicitly evaluating the reaction force by applying the present method. We discuss possible resolutions of these issues.

description: Mixed solid compounds are employed in a vast array of applications so an accurate determination of their chemical compositions is of crucial importance. All current characterization methods require specially-treated samples so the availability of a more practical method with similar accuracy should alleviate the quantification process. In this work, we show how the doping concentration $δ$ (or isotope concentration) of a mixed solid compound in powdered form, where both parent compounds are diamagnetic, can be obtained from the measurement of the mass magnetization. We exploit the additive nature of the molar magnetic susceptibility $χ_{Mol}$ and molar mass to construct two equations with the same two unknowns in the $χ_{Mol}$ vs. $δ$ space to simultaneously solve $χ_{Mol}$ and $δ$ of a mixed solid. Eight examples are provided to show the wide applicability of this method: NH$_{4(1-δ)}$D$_{4δ}$Br (where D = $^2$H), NH$_4$I$_{1-δ}$Br$_δ$, (NH$_4$H$_2$)$_{1-δ}$(ND$_4$D$_2$)$_δ$PO$_4$, C$_{48}$H$_{22+6δ}$Br$_{6(1-δ)}$O$_{32}$Zr$_6$, [creatine]$_{1-δ}$[$_D$-glucose]$_δ$, [$_L$-glutamic acid]$_{1-δ}$[$_L$-leucine]$_δ$, [terephthalic acid]$_{1-δ}$[trimesic acid]$_δ$ and [p-terphenyl]$_{1-δ}$[triphenylphosphine]$_δ$. Experimental errors of ~1.2% were obtained for $δ$ from average sample masses of 16.6 mg in powdered form rendering the presented approach an attractive choice for characterizing the ratios of mixed solids.

description: Transit signal priority (TSP) has been implemented to transit systems in many cities of the United States. In evaluating TSP systems, more attention has been given to its operational effects than to its safety effects. Existing studies assessing safety effects of TSP reported mixed results, indicating that the safety effects of TSP vary in different contexts. In this study, TSP implementations in Portland, Oregon, were assessed using interrupted time series analysis (ITSA) on month-to-month changes in number of crashes from January 1995 to December 2010. Single-group and controlled ITSA were conducted for all crashes, property-damage-only crashes, fatal and injury crashes, pedestrian-involved crashes, and bike-involved crashes. Evaluation of the post-intervention period (2003 to 2010) showed a reduction in all crashes on street sections with TSP (-4.5 percent), comparing with the counterfactual estimations based on the control group data. The reduction in property-damage-only crashes (-10.0 percent) contributed the most to the overall reduction. Fatal and injury crashes leveled out after TSP implementation but did not change significantly comparing with the control group. Pedestrian and bike-involved crashes were found to increase in the post-intervention period with TSP, comparing with the control group. Potential reasons to these TSP effects on traffic safety were discussed.

Family Farmers to Foreign Fieldhands: Consolidation of Canadian Agriculture and the Temporary Foreign Worker Program
Creators: name: Falconer, Robert
Publisher: name: The School of Public Policy Publications
Year: 2020

description: In the era of the COVID-19 pandemic, questions regarding the participation of temporary foreign workers (TFWs) in the Canadian workforce may seem reasonable. With borders closed to most international traffic due to public health concerns, and high levels of unemployment, the Canadian public, policy makers, and even employers may question the need to employ workers from abroad (Statistics Canada 2020; CBSA 2020). In addition to concerns over the health and employment of Canadians, the spread of COVID-19 among migrant workers has raised alarm over the security of both our food supply chain and the safety of workers (Rodriguez 2020; Yasmeen, Alexander, and Paskal 2020). These concerns have prompted policy makers at the federal level to study the issue in greater detail, and calls from advocates for expanded worker rights and protections (Migrant Rights 2020; HUMA 2020). In this briefing paper we provide answers to some of the above concerns. We begin by outlining the necessary role of foreign workers in Canadian agriculture. Despite the sometimes-common notion that TFWs displace domestic workers, we present data that provides a more plausible history of the program. We demonstrate that, following the Second World War, Canadian agriculture underwent significant consolidation and a steep drop in the number of smallholder farms and unpaid family members working on them. As average farm sizes increased and the unpaid labour force fell, producers responded with efforts to mechanize their outfits and offer higher wages for paid employees. Despite efforts to attract local workers, the number of domestic labourers in food production has fluctuated between stagnation and marginal decline. The participation of foreign workers in Canadian food production may have little to do with the displacement of domestic workers in comparison to the consolidation of agriculture, the exit of own-account workers and unpaid family members from the sector, and their substitution with capital investment and expansion of the labour pool beyond the border. This narrative of industrial transformation rather than displacement should inform the decisions of policy makers. Governments desiring to shutter the TFW program and replace the labour pool it provides with domestic workers may find little uptake among Canadians, replacing foreign workers with a shortage of workers. Producers may not be able to rapidly substitute towards further mechanization of food production, potentially resulting in higher prices at grocery stores, a reduction in exports, and greater reliance on imported food. We instead provide several suggestions that the federal and provincial governments may wish to consider to protect the lives and supply of foreign workers, and thereby secure the Canadian agricultural sector.

description: CRM1 is a nuclear export receptor that has been intensively targeted over the last decade for the development of antitumor and antiviral drugs. Structural analysis of several inhibitor compounds bound to CRM1 revealed that their mechanism of action relies on the covalent modification of a critical cysteine residue (Cys528 in the human receptor) located in the nuclear export signal‐binding cleft. This study presents the crystal structure of human CRM1, covalently modified by 2‐mercaptoethanol on Cys528, in complex with RanGTP at 2.58 Å resolution. The results demonstrate that buffer components can interfere with the characterization of cysteine‐dependent inhibitor compounds.

description: From extensive Monte Carlo simulations of a Larson model of perfectly periodic heteropolymers (PHP) in water a striking stiffening is observed as the period of the alternating hydrophobic and hydrophilic blocks is shortened. At short period and low temperature needle-like conformations are the stable conformation. As temperature is increased thermal fluctuations induce kinks and bends. At large periods compact oligomeric globules are observed. From the generalized Larson prescription, originally developed for modelling surfactant molecules in aqueous solutions, we find that the shorter is the period the more stretched is the PHP. This novel effect is expected to stimulate polymer synthesis and trigger research on the rheology of aqueous periodic heteropolymer solutions.

description: Papillary thyroid cancer (PTC) is a common tumor malignancy of the endocrine system worldwide. Recently, circular RNAs (circRNAs) have been reported to participate in diverse pathological processes, especially in tumorigenesis. However, the functional role and mechanism of circRNA pleckstrin and Sec7 domain containing 3 (circ-PSD3) in PTC are still unclear. In this study, qRT-PCR results showed that circ-PSD3 was significantly upregulated in PTC tissues and cell lines. Meanwhile, circ-PSD3 overexpression was positively associated with larger tumor size, TNM stage, and lymph node metastasis. Knockdown of circ-PSD3 suppressed the proliferation and invasion of PTC cells. Besides, circ-PSD3 interacted with miR-7-5p to reduce its expression, and methyltransferase like 7B (METTL7B) was verified as a target gene of miR-7-5p. Functionally, inhibition of circ-PSD3 impeded PTC cell proliferation and invasion via targeting miR-7-5p to downregulate METTL7B expression. Taken together, silencing of circ-PSD3 hampered the proliferation and invasion of PTC cells via upregulating the inhibitory effect of miR-7-5p on METTL7B expression. Therefore, circ-PSD3 could be a potential diagnostic biomarker or molecular treatment target for PTC.

description: V1247 Orionis harbours a pre-transitional disc with a partially cleared gap. Earlier interferometric and polarimetric observations revealed strong asymmetries both in the gap region and in the outer disc. The presence of a companion was inferred to explain these asymmetric structures and the ongoing disc clearing. Using an extensive set of multi-wavelength and multi-epoch observations we aimed to identify the origin of the previously detected asymmetries. We have observed V1247 Ori at three epochs spanning $\sim678$ days using sparse aperture masking interferometry with Keck/NIRC2 and VLT/NACO. In addition, we search for signs of accretion through VLT/SPHERE-ZIMPOL spectral differential imaging in H$α$ and R-band continuum. Our SMA sub-millimetre interferometry in 880 $μ$m continuum and in the CO(3-2) line allows us to constrain the orientation and direction of rotation of the outer disc. We find the L'-band emission to be dominated by static features which trace forward-scattered dust emission from the inner edge of the outer disc located to the north-east. In H- and K-band, we see evidence for a companion candidate that moved systematically by 45$^{\circ}$ within the first $\sim$345 days. The separation of the companion candidate is not well constrained, but the observed position angle change is consistent with Keplerian motion of a body located on a 6 au orbit. From the SMA CO moment map, the location of the disc rim, and the detected orbital motion, we deduced the three-dimensional orientation of the disc. We see no indication of accretion in H$α$ and set upper limits for an accreting companion. The measured contrast of the companion candidate in H and K is consistent with an actively accreting protoplanet. Hence, we identify V1247 Ori as a unique laboratory for studying companion-disc interactions and disc clearing.

description: We study the dynamical properties of the fully frustrated Ising model. Due to the absence of disorder the model, contrary to spin glass, does not exhibit any Griffiths phase, which has been associated to non-exponential relaxation dynamics. Nevertheless we find numerically that the model exhibits a stretched exponential behavior below a temperature T_p corresponding to the percolation transition of the Kasteleyn-Fortuin clusters. We have also found that the critical behavior of this clusters for a fully frustrated q-state spin model at the percolation threshold is strongly affected by frustration. In fact while in absence of frustration the q=1 limit gives random percolation, in presence of frustration the critical behavior is in the same universality class of the ferromagnetic q=1/2-state Potts model.

Six flavonoids; isoquercitrin, kaempferol-3-neohesperidoside, myricetin-3-galactoside, apigenin-O-hexoside, isorhamnetin and isorhamnetin-3-neohesperidoside, were identified for the first time in Sp leaves using LC-ESI-QTOF MS/MS analysis. The flavonoid-rich fraction obtained after purification of S1 (S1TF7) has the highest TFC (358.88 ± 0.12 mg rutin equivalent/g) and TPC (180.82 ± 0.82 mg gallic acid equivalent/g) and exhibits significant (p < 0.05) free-radical scavenging activity in DPPH(IC50% = 14.64 ± 0.29 µg/mL) and ABTS (IC50% = 200.41 ± 1.85 µg/mL) assays which was similar to Butylated hydroxytoluene (BHT) as a positive control (IC50% =12.94 ± 0.10 µg/mL and IC50% = 190.47 ± 8.93 µg/mL, respectively). Also, S1TF7 inhibits Lipopolysaccharide (LPS)-stimulated ROS production in raw-cell-264.7 with no significant toxicity at 200 µg/mL (p > 0.05). The study concludes that S1TF7 can serve as a mean to prevent oxidative diseases, and it merits further pharmacological investigations.

description: Directly-imaged planetary-mass companions offer unique opportunities in atmospheric studies of exoplanets. They share characteristics of both brown dwarfs and transiting exoplanets, therefore, are critical for connecting atmospheric characterizations for these objects. Rotational phase mapping is a powerful technique to constrain the condensate cloud properties in ultra-cool atmospheres. Applying this technique to directly-imaged planetary-mass companions will be extremely valuable for constraining cloud models in low mass and surface gravity atmospheres and for determining the rotation rate and angular momentum of substellar companions. Here, we present Hubble Space Telescope Wide Field Camera 3 near-infrared time-resolved photometry for three planetary-mass companions, AB Pic B, 2M0122B, and 2M1207b. Using two-roll differential imaging and hybrid point spread function modeling, we achieve sub-percent photometric precision for all three observations. We find tentative modulations ($

description: Typical sources of gravitational wave bursts are supernovae, for which no accurate models exist. This calls for search methods with high efficiency and robustness to be used in the data analysis of foreseen interferometric detectors. A set of such filters is designed to detect gravitational wave burst signals. We first present filters based on the linear fit of whitened data to short straight lines in a given time window and combine them in a non linear filter named ALF. We study the performances and efficiencies of these filters, with the help of a catalogue of simulated supernova signals. The ALF filter is the most performant and most efficient of all filters. Its performance reaches about 80% of the Optimal Filter performance designed for the same signals. Such a filter could be implemented as an online trigger (dedicated to detect bursts of unknown waveform) in interferometric detectors of gravitational waves.

description: Sport und Medien bilden nicht nur zwei gesellschaftliche Bereiche, sondern sind in unserer heutigen Gesellschaft auch bereits als feste Bestandteile verankert, welche nunmehr in enger Verwobenheit interagieren. Die vorliegende Masterarbeit rückt hierbei vor allem die Sportart Tennis zentral in den Fokus. Ziel dieser Arbeit ist es, die – vor allem auf sprachlicher Ebene basierenden – Merkmale und Besonderheiten der Sportsprache ausgewählter österreichischer Hauptkommentatoren sowie Co-Kommentatoren in TV-Übertragungen des Tennissports zu analysieren und zu vergleichen. Der Schwerpunkt liegt dabei sowohl auf einer diachronen Analyse des Wandels der Sportsprache wie auch auf synchronen Unterschieden hinsichtlich der Hauptkommentatoren und Co-Kommentatoren des Tennissports, die im Rahmen der TV-Sender ORF 1, ORF Sport+ sowie ServusTV tätig sind. Auf Basis der theoretischen Ausführungen vorweg sowie der Untersuchung von Live-Kommentierungen ausgewählter Tennismatches der Erste Bank Open 2022 anhand der qualitativen Inhaltsanalyse nach Mayring (2022) werden unterschiedliche sprachliche Kategorien sowohl aus diachroner als auch aus synchroner Perspektive beleuchtet. Die Ergebnisse der diachronen Analyse zeigen dabei, dass die literaturbasierten Tendenzen hinsichtlich des diachronen Sprachwandels der Sportsprache nunmehr – bis auf geringfügige Ausnahmen und Ergänzungen – großteils auch auf sprachlicher Ebene im Bereich der Live-Kommentierungen speziell im Feld des Tennissports abgezeichnet werden können, während aus synchroner Sicht etwa gruppenspezifische sprachliche Unterschiede im Hinblick auf Hauptkommentatoren und Co-Kommentatoren festgestellt werden können, beispielsweise hinsichtlich des Einsatzes von Antonomasien, bildhaften Adjektiven, Neologismen und Wortneuschöpfungen, Metaphern oder der Verwendung der ersten Person Plural zur Emotionalisierung und Bildung eines kollektiven Identitätsgefühls. Demgegenüber differieren einzelne Kommentatoren aufgrund unterschiedlicher individueller sprachlicher Merkmale, die vor allem in stark emotionalisierenden Momenten in Erscheinung treten.

description: We present uvbybeta CCD photometry of the central region of the double cluster h and chi Persei. We identify 350 stars, of which 214 were not included in Oosterhof catalogue. Our magnitude limit V=16.5 allows us to reach early F spectral type and obtain very accurate fits to the ZAMS. We derive reddening values of E(b-y)=0.44+-0.02 for h Persei and E(b-y)=0.39+-0.05 for chi Persei. From the ZAMS fitting, we derive distance moduli V0-Mv=11.66+-0.20 and V0-Mv=11.56+-0.20 for h and chi Persei respectively. These values are perfectly compatible with both clusters being placed at the same distance and having identical reddenings. The shift in the main-sequence turnoff and isochrone fitting, however, show that there is a significant age difference between both clusters, with the bulk of stars in h Persei being older than chi Persei. There is, however, a significant population of stars in h Persei which are younger than chi Persei. All this argues for at least three different epochs of star formation, corresponding approximately to log t=7.0, 7.15 and 7.3.

description: A unified numerically solvable framework for dispersion relations with arbitrary number of species drifting at arbitrary directions and with Krook collision is derived for linear uniform/homogenous kinetic plasma, which largely extended the standard one [say, T. Stix, {\em Waves in Plasmas}, AIP Press, 1992]. The purpose of this work is to provide a kinetic plasma dispersion relation tool not only the physical model but also the numerical approach be as general/powerful as possible. As a very general application example, we give the final dispersion relations which assume further the equilibrium distribution function be bi-Maxwellian and including parallel drift, two directions of perpendicular drift (i.e., drift across magnetic field), ring beam and loss-cone. Both electromagnetic and electrostatic versions are provided, with also the Darwin (a.k.a., magnetoinductive or magnetostatic) version. The species can be treated either magnetized or unmagnetized. Later, the equations are transformed to the matrix form be solvable by using the powerful matrix algorithm [H. S. Xie and Y. Xiao, Plasma Science and Technology, 18, 2, 97, 2016], which is the first approach can give all the important solutions of a linear kinetic plasma system without requiring initial guess for root finding and thus can be extremely useful to the community. To our knowledge, the present model would be the most comprehensive one in literature for the distribution function constructed bases on Maxwellian, which thus can be applied widely for study waves and instabilities in space, astrophysics, fusion and laser plasma. We limit the present work to non-relativistic case.

description: Die Bewertung von Archivalien in lokalen Archiven ist ein sehr komplexer und vielfältiger Prozess. Jedes Archiv hat seine eigene Art und Weise und Spezifikation, deshalb unterscheidet sich jede Archivbewertung von den anderen. In erster Linie ist der zuständige Archivar der Grund dafür, denn er entscheidet in den meisten Fällen, welche Archivalien im Archiv verbleiben und welche Dokumente für das Verständnis der historischen Prozesse weniger wichtig sind und deshalb vernichtet werden können. Neben der potentiellen Bedeutung der Archivalien gibt es einige Faktoren, die ebenso entscheidend sind wie die Entscheidungen des jeweiligen Archivars. In den meisten Archiven mangelt es an finanziellen, personellen und räumlichen Ressourcen. Vor allem die räumlichen Ressourcen haben einen Einfluss darauf, welche Archivalien aufbewahrt und welche vernichtet werden. In den meisten Gemeinden haben die Archive nicht den gleichen Stellenwert wie andere Verwaltungseinrichtungen. In vielen Fällen sind sie Teil einer anderen Abteilung innerhalb der Gemeinde. Diese Arbeit befasst sich mit der archivischen Bewertung in Kommunalarchiven im Allgemeinen, um zu zeigen, wie vielfältig der Prozess sein kann. Weiters wird es ein Kapitel über die Geschichte des Stadtarchivs geben, um dessen lange historische Entwicklung aufzuzeigen. Der Hauptteil dieser Arbeit beschäftigt sich mit der Geschichte des Stadtarchivs in Neusiedl am See und der Darstellung aller Archivalien des Stadtarchivs, indem aufgezeigt wird, welche Archivalien vorhanden sind und welchen Inhalt sie haben. Die Arbeit beschäftigt sich vor allem mit diesen Aspekten: Welche Unterlagen werden im Archiv aufbewahrt? Nach welchen Bewertungskriterien werden Unterlagen in das Archiv aufgenommen? Gibt es Unterlagen, die vernichtet werden? Gibt es Maßnahmen der Schriftgutverwaltung? Enthält das Stadtarchiv digitale Daten? Welche Überlegungen gibt es zur Bewertung und Archivierung digitaler Daten?

description: In the age of neural natural language processing, there are plenty of works trying to derive interpretations of neural models. Intuitively, when gold rationales exist during training, one can additionally train the model to match its interpretation with the rationales. However, this intuitive idea has not been fully explored. In this paper, we propose a framework of utilizing interpretation methods and gold rationales to enhance models. Our framework is very general in the sense that it can incorporate various interpretation methods. Previously proposed gradient-based methods can be shown as an instance of our framework. We also propose two novel instances utilizing two other types of interpretation methods, erasure/replace-based and extractor-based methods, for model enhancement. We conduct comprehensive experiments on a variety of tasks. Experimental results show that our framework is effective especially in low-resource settings in enhancing models with various interpretation methods, and our two newly-proposed methods outperform gradient-based methods in most settings.
