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.

description: This study investigates the critical agents that cause non-Darrian flow in porous media. Four porous media different in morphology but similar in topology were studied numerically. By varying the throat diameters, the distinct roles of pores and throats in total dissipation were investigated using direct numerical simulation. Forchheimer model was selected to analyze the non-Darcian flow. In our simplified geometry, the ratio KappKD can best be correlated by non-Darcy effect (E). Total dissipation is directly related to the porous medium resistance against fluid flow. The energy dissipated in pores and throats was calculated by summing the dissipation in each computational segment. Pores are more prone to disobey the Darcy model than throats due to irregularity in fluid flow, and they are introduced as the cause of Darcy-model cessation. By increasing the pore-to-throat ratio, the non-Darcian flow in the pores begins sooner. The results show that the energy dissipation due to eddies is negligible. The dissipation in pores and throats was simulated through separate power-law equations, and their exponents were also extracted. The exponent for the pore body is equal to two when the viscous forces are dominant, and it increases by increasing the inertia force. The dissipation due to pore bodies is more apparent when the size of pore and throats are of the same order of magnitude. The relative losses of pore body increase as the velocity increases, in contrast to throats.

description: In spite of the recent surge of interest in quantile regression, joint estimation of linear quantile planes remains a great challenge in statistics and econometrics. We propose a novel parameterization that characterizes any collection of noncrossing quantile planes over arbitrarily shaped convex predictor domains in any dimension by means of unconstrained scalar, vector and function valued parameters. Statistical models based on this parameterization inherit a fast computation of the likelihood function, enabling penalized likelihood or Bayesian approaches to model fitting. We introduce a complete Bayesian methodology by using Gaussian process prior distributions on the function valued parameters and develop a robust and efficient Markov chain Monte Carlo parameter estimation. The resulting method is shown to offer posterior consistency under mild tail and regularity conditions. We present several illustrative examples where the new method is compared against existing approaches and is found to offer better accuracy, coverage and model fit. Supplementary materials for this article are available online.

description: Aiming to verify which is the most effective screening approach for sleep disorders between the serial (first step: sleep self-report measure; second step only in case of positive outcome at the first: objective tool) and parallel (unique step, with the concurrent use of sleep self-report measure and objective tool), a first secondary analysis of previously collected data (study 1) was carried out examining primary insomniacs (PI) and healthy controls (HC). Aiming to verify the implementation of such approaches in clinical populations presenting high comorbidity with sleep disorder, an additional secondary analysis (study 2) was carried out, investigating hypertensive patients (HP) and severe obese patients (SOP). 84 HC and 47 PI were examined in study 1, while 36 SOP, and 30 HP in study 2. All participants originally underwent actigraphic recordings for seven consecutive days, using the Actiwatch device (objective tool). At the end of the recording week, participants filled the Mini Sleep Questionnaire (sleep self-report measure). As regards the study 1, the parallel and serial approaches allowed to correctly identify the 97.87% and 55.32% of PI, respectively. With reference to the study 2, the 36.11% and 80.56% of SOP were identified as positive at the serial and parallel approaches, respectively, while the corresponding percentages of HP were 30% and 70%. Study 1 showed that parallel screening approach is the most effective in PI, allowing to correctly identifying almost the entirety of these patients. Study 2 highlighted that serial screening approach is more useful in SOP and HP, identifying a percentage of positive patients overall in line with the documented comorbidity with sleep disorder in these clinical populations.

description: One-pot solvothermal treatment of Co(NO3)2·6H2O, H2L (5-(3-methyl-5-(pyridin-4-yl)-4H-1,2,4-triazol-4-yl) isophthalic acid), and 4,4′-bipyridine (4,4′-bipy) in H2O/DMF (V/V = 1 : 1) yielded a cobalt-organic chain, [Co(L)(O)(H2O)2]n·1.25nH2O (1). Compound 1 as raw materials was calcined to obtain Co3O4, which could be confirmed by PXRD and SEM. Via the modification, Co3O4@SiO2-NH2 and Co3O4@SiO2-NH2-FA samples could be obtained. Compared to Co3O4@SiO2-NH2, Co3O4@SiO2-NH2-FA seems to have better peroxidase-mimetic properties. UV–vis results showed that optimal conditions of peroxidase-mimetic experiments were at 50°C in sodium acetate-acetic acid buffer (pH 3.6, 0.2 M), when the concentration of tetramethylbenzidine (TMB) was 0.2 mM. A concentration-dependent manner was shown between the concentration of glucose and absorbance in the measurement experiments for glucose.

description: Solanum cernuum is a medicinal plant widely distributed in south-east regions of Brazil and popularly used to treat several disorders. Despite their utilisation as a medicine, few studies on its chemical composition are reported. An efficient separation method for the ethyl acetate fraction was developed by high-performance countercurrent chromatography using n-butanol/chloroform/methanol/water (3:7:3:4, v/v/v/v) as the solvent system, affording five compounds (1–5) in one-step separation. A new cyclic guanidine alkaloid named cernidine (5) was obtained, besides four glycosylated flavonoids: afzelin (1), astragalin (2), kaempferol 3-O-α[apiofuranosyl-(1 → 2)]-α-rhamnopyranoside (3) and kaempferol 3-O-α[apiofuranosyl-(1→2)]-β-galactopyranoside (4). A further purification step afforded a mixture of trans- and cis-tiliroside (6–7). Countercurrent chromatography proved itself as a powerful tool for the isolation of similar compounds since compounds 1–2 and 3–4 possess little structural differences.

Subjects: Learning Analytics, epistemology, methodology, ethics

description: This article reports on a debate conducted in 2019 in the "Débat-discussion" section of the four issues of the journal Distance et Mediation of Knowledge (DMS-DMK). Each year, the section is the site of a thematic debate which opens in the first of the four annual issues with a framing text. It offers a critical review of the recent literature devoted to the chosen theme: it analyzes its potential, the challenges and the prospects, particularly for distance learning. During the following three issues, fellow specialists in the field are invited to react, to debate based on their epistemological positioning, their disciplinary affiliation, their research and their experience. The article presents a synthesis, albeit partial, of the debate that Learning Analytics were the subject of in the review during the year 2019: it focuses on epistemological, methodological and ethical arguments.

description: Phytochemical investigation of the stem bark of Campylospermum zenkeri led to the isolation of five known compounds: (Z,Z)-9,12-octadecadienoic acid (1), serotobenine (2), agathisflavone (3), lophirone A (4) and lophirone F (5), together with a new derivative of procyanidin B, a catechin dimer named zenkerinol (6). Serotobenine (2) is structurally related to decursivine which shows moderate activity against D6 and W2 strains of Plasmodium falciparum. For a better understanding of structure-activity relationships, three new semi-synthetic derivatives of serotobenine (2) have been prepared. These are: serotobenine monopropionate (2a), serotobenine monopivalate (2b) and serotobenine cyclohexyl ether (2c) respectively. Two of them (2a) and (2b), were evaluated for their antiplasmodial activity against P. falciparum 3D7 strain in a parasite lactate-dehydrogenase (pLDH) assay. Compound 2b was more active than compound 2a based on their IC50 values (36.6 and 123 μM, respectively).

description: βγ-Crystallins are a superfamily of proteins containing crystallin-type Greek key motifs. Some βγ-crystallin domains have been shown to bind Ca2+. Hahellin is a newly identified intrinsically disordered βγ-crystallin domain from Hahella chejuensis. It folds into a typical βγ-crystallin structure upon Ca2+ binding and acts as a Ca2+-regulated conformational switch. Besides Hahellin, another two putative βγ-crystallins from Caulobacter crescentus and Yersinia pestis are shown to be partially disordered in their apo-form and undergo large conformational changes upon Ca2+ binding, although whether they acquire a βγ-crystallin fold is not known. The extent of conformational disorder/order of a protein is determined by its amino acid sequence. To date how this sequence–structure relationship is reflected in the βγ-crystallin superfamily has not been investigated. In this work, we comparatively studied the sequence and structure of Hahellin with those of Protein S, an ordered βγ-crystallin, via various computational biophysical techniques. We found that several factors, including presence of a C-terminal disorder prone region, high content of energetic frustrations, and low contact density, may promote the formation of the disordered state of apo-Hahellin. We also analyzed the disorder propensities for other putative disordered βγ-crystallin domains. This study provides new clues for further understanding the sequence–structure–function relationship of βγ-crystallins.

description: Two new organotin compounds, triphenyl-4,6-diamine-pyrimidine-2-thione-tin(IV) (1) and triphenyl-imidazoline-2-thione-chloro-tin(IV) (2), have been synthesized, spectroscopically and structurally characterized, and their cytotoxic activities have been tested against certain cancer cell lines. Atoms-In-Molecules approach has been applied for the description of the coordination geometry. Both complexes are active against chemotherapy-resistant SK-LMS-1 Leiomyiosarcoma cells (IC50 of 0.1 μM), and this activity is 3–4 times larger than against normal human CCD39Lu fibroblasts. The biological activity results are compared with those determined for other active organotin compounds which have Sn-S bond, and structure-activity relationships including geometry, intermolecular interactions, Hirshfeld surface parameters, etc., are discussed. Besides the anticancer activity, 2 is also unique from structural point of view as the first structure of a triphenyltin complex with Sn coordinated by both sulfur and halide.

description: The use of imaging markers to predict clinical outcomes can have a great impact in public health. The aim of this article is to develop a class of generalized scalar-on-image regression models via total variation (GSIRM-TV), in the sense of generalized linear models, for scalar response and imaging predictor with the presence of scalar covariates. A key novelty of GSIRM-TV is that it is assumed that the slope function (or image) of GSIRM-TV belongs to the space of bounded total variation to explicitly account for the piecewise smooth nature of most imaging data. We develop an efficient penalized total variation optimization to estimate the unknown slope function and other parameters. We also establish nonasymptotic error bounds on the excess risk. These bounds are explicitly specified in terms of sample size, image size, and image smoothness. Our simulations demonstrate a superior performance of GSIRM-TV against many existing approaches. We apply GSIRM-TV to the analysis of hippocampus data obtained from the Alzheimers Disease Neuroimaging Initiative (ADNI) dataset. Supplementary materials for this article are available online.

description: 3-D printing is an additive manufacturing process involving the injection of melted thermoplastic polymers, which are then laid down in layers to achieve a pre-designed shape. The heated deposition process raises concerns of potential aerosol and volatile organic compounds (VOC) emission and exposure. The decreasing cost of desktop 3-D printers has made the use of 3-D printers more acceptable in non-industrial workplaces lacking sufficient ventilation. Meanwhile, little is known about the characteristics of 3-D printing fume emission. The objective of this study was to characterize aerosols and VOC emissions generated from various filaments used with a low-cost 3-D printer in an environmental testing chamber. A pre-designed object was printed in 1.25 hours using eight types of filaments. A scanning mobility particle sizer and an aerodynamic particle sizer were employed to measure the particle size distribution in sub-half-micron fraction (<0.5 µm) and super-half-micron fraction (0.5–20 µm), respectively. VOC concentration was monitored real-time by a photoionization detector and sampled with a tri-sorbent thermal desorption tube, and analyzed by thermal desorption gas chromatography mass spectrometry (TD-GC/MS). Results showed high levels of fume particles emission rate (1.0 × 107 to 1.2 × 1010 #/min) in the sub-half-micron range with mode sizes of 41–83 nm. Particle concentrations peaked during the heat-up and solid layer printing periods. Total VOC concentration in the chamber followed a first-order buildup, with predominant VOC species in the chamber were breakdown and reaction products of the filaments, such as styrene from ABS filaments. These findings and exposure scenario estimation suggest that although the VOC concentrations were much lower than occupational exposure limits, particles with size less than micron might be a concern for users of low-cost 3-D printers due to high respirablity, especially if used in settings without proper guidance and engineering control.

description: We analyze the harvesting and stocking of a population that is affected by random and seasonal environmental fluctuations. The main novelty comes from having three layers of environmental fluctuations. The first layer is due to the environment switching at random times between different environmental states. This is similar to having sudden environmental changes or catastrophes. The second layer is due to seasonal variation, where there is a significant change in the dynamics between seasons. Finally, the third layer is due to the constant presence of environmental stochasticity -- between the seasonal or random regime switches, the species is affected by fluctuations which can be modelled by white noise. This framework is more realistic because it can capture both significant random and deterministic environmental shifts as well as small and frequent fluctuations in abiotic factors. Our framework also allows for the price or cost of harvesting to change deterministically and stochastically, something that is more realistic from an economic point of view.
 The combined effects of seasonal and random fluctuations make it impossible to find the optimal harvesting-stocking strategy analytically. We get around this roadblock by developing rigorous numerical approximations and proving that they converge to the optimal harvesting-stocking strategy. We apply our methods to multiple population models and explore how prices, or costs, and environmental fluctuations influence the optimal harvesting-stocking strategy. We show that in many situations the optimal way of harvesting and stocking is not of threshold type.

description: 3-D printing is an additive manufacturing process involving the injection of melted thermoplastic polymers, which are then laid down in layers to achieve a pre-designed shape.

description: Myelin formation during peripheral nervous system development, as well as myelin repair after injury and in disease, requires multiple intrinsic and extrinsic signals. Neurotrophin-4 (NT-4) is a member of the neurotrophin family, which regulates the development of neuronal networks by participating in the growth of neuronal processes, synaptic development and plasticity, neuronal survival, and differentiation. However, the intracellular signaling pathways by which NT-4 participates in myelination by Schwann cells remain elusive. In this study, we examined the effects of NT-4 on the expression of compact myelin proteins in cultured Schwann cells. Using real-time quantitative RT-PCR and western blotting, we found that NT-4 could significantly enhance the expression of myelin protein zero (MPZ) but not the expression of myelin basic protein or peripheral myelin protein 22. Further, knockdown of truncated TrkB with small interfering RNA could eliminate the effect of NT-4 on MPZ expression. Moreover, we demonstrated that the NT-4-enhanced MPZ expression depended on Akt and mTORC1 signaling. Taken together, these results suggest that NT-4 binds TrkB to enhance the expression of MPZ in Schwann cells, probably through the PI3K/Akt/mTORC1 signaling pathway, thus contributing to myelination.

description: Platelets are recognized to be physiologically and functionally heterogeneous. An example of the diversity in reactivity is the formation of a distinct subpopulation of procoagulant phosphatidylserine (PS)-exposing platelets upon activation. Platelet age has been proposed as a determinant of platelet function, and it has been reported that young platelets are more reactive in exposing PS; using the same methodology of thiazole orange (TO) staining to distinguish young and old platelets, the percentages of procoagulant platelets produced by thrombin plus collagen activation of platelets from healthy controls were examined by flow cytometry. The procoagulant subpopulation formed by TO-positive platelets (with high TO fluorescence), purported to be young reticulated platelets, was observed to be significantly larger than that formed by TO-negative platelets (with low TO fluorescence), purported to be older platelets. However, it was noted that TO fluorescence in the total platelet population was unimodal and increased with platelet size, assessed by forward scatter. This observation raised the concern that TO-positive platelets are not necessarily the youngest platelets in the condition of steady-state platelet production. Thus, to unequivocally determine whether platelet age is a factor in procoagulant platelet formation, a different approach to identify young, steady-state platelets was employed. Rabbits were injected with biotin to label >95% of circulating platelets in vivo; 24 hours post-biotinylation, the non-biotinylated platelets in the circulation, detected flow cytometrically, are the youngest, newly-formed platelets. It was demonstrated that these youngest platelets were not larger in size than older, biotinylated platelets, and that they did not have an enhanced capacity to expose PS.

Instruction Set Completeness Theorem: Concept, Relevance, Proof, and Example for Processor Architecture

description: The Instruction Set Completeness Theorem is first formally defined and discussed in the seminal work on one-instruction set computing—the book Computer Architecture: A Minimalist Perspective. Yet the original formalism of the Instruction Set Completeness Theorem did not provide a definitive, explicit mathematical proof of completeness, analyze both singular and plural instruction sets that were either complete or incomplete, nor examine the significance of the theorem to computer architecture instruction sets. A mathematical proof of correctness shows the equivalence of the Instruction Set Completeness Theorem to a Turing machine, a hypothetical model of computation, and thereby establishes the mathematical truth of the Instruction Set Completeness Theorem. With a more detailed examination of the Instruction Set Completeness Theorem develops several surprising conclusions for both the instruction set completeness theorem, and the instruction sets for a computer architecture.

description: Mechatronische Fahrwerke mit aktiver Spurführung können Verschleiß und Lärm im Vergleich zu konventionellen Fahrwerken durch Vermeidung des Spurkranzanlaufs reduzieren. Trotz wissenschaftlicher Untersuchungen, die das Potential aufzeigen, wird eine technische Umsetzung selten vorgenommen. Dies liegt unter anderem an unzureichender Verfügbarkeit von geeigneter Messtechnik, insbesondere von Sensoren. Zur Regelung des Spurführungsverhaltens benötigen mechatronische Fahrwerke Kenntnisse über ihren aktuellen Zustand. Am Markt erhältliche Sensoren sind oft ungeeignet, wichtige Zustandsgrößen am Fahrwerk während der Fahrt direkt zu messen. Alternative Ansätze, die interessierenden Größen über Zustandsschätzer ableiten, sind oft unzureichend genau. In dieser Arbeit wird anhand eines aktiv gelenkten Radpaars ein neues Sensorkonzept zur direkten Bestimmung der Zustandsgrößen Anlaufwinkel und Lateralversatz vorgestellt. Aus den Anforderungen mechatronischer Fahrwerke wird mittels des V-Modells in drei Makrozyklen ein Sensorkonzept entwickelt und prototypisch aufgebaut. Das Sensorkonzept nutzt dabei die ferromagnetischen Eigenschaften der Schiene. Ein durch den Sensor künstlich erzeugtes Magnetfeld wird durch die Schiene verändert, und Hallsensorelemente messen diese Veränderungen. Aus den Messdaten wird die Lateralposition der Schiene unter dem Sensor über einen Luftspalt von 20mm mit ausreichender Genauigkeit berechnet. Der Sensorprototyp wird mittels einer Simulation des aktiv gelenkten Radpaars in verschiedenen Testszenarien validiert. Mit zusätzlichen Hardware-in-the-loop-Versuchen wird gezeigt, dass das Sensorkonzept für die mechatronische Spurführung eignet ist.
