description: Quadratic unconstrained binary optimization (QUBO) can be seen as a generic language for optimization problems. QUBOs attract particular attention since they can be solved with quantum hardware, like quantum annealers or quantum gate computers running QAOA. In this paper, we present two novel QUBO formulations for $k$-SAT and Hamiltonian Cycles that scale significantly better than existing approaches. For $k$-SAT we reduce the growth of the QUBO matrix from $O(k)$ to $O(log(k))$. For Hamiltonian Cycles the matrix no longer grows quadratically in the number of nodes, as currently, but linearly in the number of edges and logarithmically in the number of nodes. We present these two formulations not as mathematical expressions, as most QUBO formulations are, but as meta-algorithms that facilitate the design of more complex QUBO formulations and allow easy reuse in larger and more complex QUBO formulations.

Révolution tranquille

description: Durant la période d’après-guerre jusqu’au milieu des années 1970, des changements de fond s’opèrent au sein de la communauté juive québécoise — basée surtout à Montréal —, qui se manifestent dans les domaines démographique, culturel, et institutionnel. Il y a notamment la perte irréversible de la langue yiddish et la refonte de l’éducation juive, deux enjeux qui évoluent parallèlement à l’ascension des Juifs montréalais dans l’échelle socioéconomique canadienne. En même temps, la collectivité juive du Québec se diversifie suite à l’immigration d’un nombre important de rescapés de l’Holocauste de tendance hassidique et de Juifs marocains francophones de culture sépharade. Dans cette thèse, nous considérons ces phénomènes selon un éclairage nouveau, à la lueur du contexte sociopolitique québécois. Notre hypothèse de base est que les particularités de la communauté juive montréalaise apparaissent sous cette lumière comme étant en partie le produit des débats sociopolitiques québécois et des contacts croissants avec les Québécois d’origine canadienne-française dès le lendemain de la guerre. Nous soutenons que les Juifs québécois se retrouvent dans une situation politique et culturelle unique en Amérique du Nord et au Canada, dont le corollaire est la formation d’une identité juive montréalaise distincte de l’identité juive canadienne et états-unienne. L'Oecuménisme d'après-guerre et les débats de société fondamentaux qui entourent l’expansion de l’État québécois à l’heure de la Révolution tranquille nous offrent un contexte pour analyser le discours médiatique articulé par une minorité religieuse et culturelle qui compte sur une forte complétude institutionnelle au Québec. Le fait de représenter un groupe minoritaire distinct offre aux commentateurs juifs de Montréal une base pour faire valoir la communauté juive en tant que composante légitime de la société québécoise alors que le néonationalisme et le souverainisme québécois se déploient. Plus encore, ce contexte provoque une réflexion distincte relativement à la pérennisation de la vie et de la culture juive au Québec dans un contexte marqué par la promotion du pluralisme civique et l'adoption de la rhétorique politique du multiculturalisme.

description: This paper presents a method for aerial manipulator end-effector trajectory tracking by encompassing dynamics of the Unmanned Aerial Vehicle (UAV) and null space of the manipulator attached to it in the motion planning procedure. The proposed method runs in phases. Trajectory planning starts by not accounting for roll and pitch angles of the underactuated UAV system. Next, we propose simulating the dynamics on such a trajectory and obtaining UAV attitude through the model. The full aerial manipulator state obtained in such a manner is further utilized to account for discrepancies in planned and simulated end-effector states. Finally, the end-effector pose is corrected through the null space of the manipulator to match the desired end-effector pose obtained in trajectory planning. Furthermore, we have applied the TOPP-RA approach on the UAV by invoking the differential flatness principle. Finally, we conducted experimental tests to verify effectiveness of the planning framework.
Attending to Absentees: An Investigation of How Four Urban Alternative Schools Respond to Absenteeism

Dropout

description: Thousands of children are absent from school every day. Students miss school for a multitude of reasons connected to the student, their family, the school, and the wider society. This research conceptualizes absenteeism as voluntary and involuntary. Voluntary absences revolve around students’ deliberate decisions to miss school; whereas involuntary absences are often imposed on the student. For example, preferring to engage in some recreational activity outside of the school is considered a voluntary absence, whereas having to work during school hours to earn an income is an involuntary absence. Unfortunately, the majority of mainstream schools do not demarcate between voluntary and involuntary absences and reprimand pupils for absenteeism regardless of its cause. As a result of these actions, many youths are pushed, pulled, or fade away from their education. A lucky few find their way to alternative schools where they are offered a last chance to earn a high school diploma. Some alternative schools are able to not only raise attendance, but also to accommodate involuntary absenteeism, where a student is allowed to miss some class without penalty. However, little Canadian evidence exists documenting how alternative schools respond to absenteeism. This research interviewed 40 students and 17 staff members in four alternative schools in Ontario, Canada, to capture their perspectives on absenteeism. The findings indicate that mainstream schools the students attended were not effective in responding to absenteeism; whereas the alternative schools were better positioned to ensure that the students were able to progress with their education regardless of their ability to attend consistently. Nevertheless, there are concerns about the pupils’ readiness to succeed in postsecondary education and/or subsequent work upon graduation from an alternative school.

description: Le test de concordance de script (TCS) est un outil qui vise à mesurer le raisonnement clinique (RC) des apprenants en contexte d’incertitude en comparaison à celui des experts. La nature de cet instrument fait en sorte que le processus de détermination des scores est névralgique et influence ainsi l’interprétation de ces derniers. Le but de cette recherche à caractère exploratoire était d’examiner l’impact de trois méthodes de détermination des scores sur les propriétés métriques des scores obtenus avec un TCS. Nous avons réalisé une analyse secondaire de données recueillies entre 2010 et 2014 auprès de 160 étudiants inscrits dans un programme de médecine familiale à l'Université de Liège en Belgique. Ainsi la théorie classique des tests et le modèle de Rasch ont été mis à contribution. Selon les résultats obtenus, la méthode selon la bonne réponse n’est pas recommandée. En revanche, la méthode des scores combinés très utilisée dans le contexte du TCS n’a pas prouvé, selon nous, sa supériorité sur la méthode avec pénalité de distance. D’autres études s’avèrent nécessaires pour approfondir ces résultats.

description: To push the radial velocity (RV) exoplanet detection threshold, it is crucial to find more reliable radial velocity extraction methods. The Least-Squares Deconvolution (LSD) technique has been used to infer the stellar magnetic flux from spectropolarimetric data for the past two decades. It relies on the assumption that stellar absorption lines are similar in shape. Although this assumption is simplistic, LSD provides a good model for intensity spectra and likewise an estimate for their Doppler shift. We present the Multi-Mask Least-Squares Deconvolution (MM-LSD) RV extraction pipeline which extracts the radial velocity from two-dimensional echelle-order spectra using LSD with multiple tailored masks after continuum normalisation and telluric absorption line correction. The flexibility of LSD allows to exclude spectral lines or pixels at will, providing a means to exclude variable lines or pixels affected by instrumental problems. The MM-LSD pipeline was tested on HARPS-N data for the Sun and selected well-observed stars with 5.7 < Vmag < 12.6. For FGK-type stars with median signal-to-noise above 100, the pipeline delivered RV time series with on average 12 per cent lower scatter as compared to the HARPS-N RV extraction pipeline based on the Cross-Correlation Function technique. The MM-LSD pipeline may be used as a standalone RV code, or modified and extended to extract a proxy for the magnetic field strength.

description: ABSTRACTThis study presents the synthesis, spectral analysis and antimicrobial evaluation of a new series of 1,3-thiazolidin-4-one derivatives. New compounds were prepared by the reaction of N-substituted carboxylic acid hydrazide derivatives with thioglycolic acid. The structures of the obtained compounds were confirmed by means of 1H NMR and 13C NMR. All the synthesized compounds were screened for their in vitro antibacterial and antifungal activities using the broth microdilution method against a panel of reference strains of 20 microorganisms, including 10 strains of Gram-positive bacteria, 7 strains of Gram-negative bacteria and fungi belonging to 3 yeasts of Candida spp. Our results indicate that some of the investigated compounds showed good to mild bioactivity, with bacteriostatic or fungistatic effect against reference strains of Gram-positive bacteria, mainly M. luteus and yeast belonging to Candida spp., especially C. albicans.

description: Specialized documentation techniques have been developed to communicate key facts about machine-learning (ML) systems and the datasets and models they rely on. Techniques such as Datasheets, FactSheets, and Model Cards have taken a mainly descriptive approach, providing various details about the system components. While the above information is essential for product developers and external experts to assess whether the ML system meets their requirements, other stakeholders might find it less actionable. In particular, ML engineers need guidance on how to mitigate potential shortcomings in order to fix bugs or improve the system's performance. We survey approaches that aim to provide such guidance in a prescriptive way. We further propose a preliminary approach, called Method Cards, which aims to increase the transparency and reproducibility of ML systems by providing prescriptive documentation of commonly-used ML methods and techniques. We showcase our proposal with an example in small object detection, and demonstrate how Method Cards can communicate key considerations for model developers. We further highlight avenues for improving the user experience of ML engineers based on Method Cards.

KL-Mat : Fair Recommender System via Information Geometry

description: Recommender system has intrinsic problems such as sparsity and fairness. Although it has been widely adopted for the past decades, research on fairness of recommendation algorithms has been largely neglected until recently. One important paradigm for resolving the issue is regularization. However, researchers have not been able to come up with a consensusly agreed regularization term like regularization framework in other fields such as Lasso or Ridge Regression. In this paper, we borrow concepts from information geometry and propose a new regularization-based fair algorithm called KL-Mat. The algorithmic technique leads to a more robust performance in accuracy performance such as MAE. More importantly, the algorithm produces much fairer results than vanilla matrix factorization approach. KL-Mat is fast, easy-to-implement and explainable.

description: This concept review paper analyses the possibility to develop a technical solution for the challenging reaction of CO$_2$ splitting to carbon and O$_2$ (CO$_2$tC). This is a dream reaction in the area of addressing climate change and greenhouse gas emissions. There are quite limited literature indications that were reviewed, with an analysis also of the limits and perspectives. Not-thermal plasma, in combination with catalysis, is one of the possibilities to promote this reaction. Current studies on plasma-assisted CO$_2$ splitting are limited mainly to the formation of CO. By combining data on the status of current studies on plasma CO$_2$ splitting with those on CO$_2$tC it is possible to propose a tentative novel approach. This is a conceptual idea presented and discussed as vehicle to stimulate research in the area, including proposing alternative possibilities. The challenges of this concept and reaction are discussed.

description: An aluminium phthalocyanine complex covalently bonded to the silica surface of mesoporous MCM-41 molecular sieve was successfully applied as a catalyst for hydrophosphorylation of various imines. The immobilized catalyst exhibited a high catalytic activity, stability and reusability under various conditions for the synthesis of the wide range of α-amino phosphonates based on aminoacid ketimines, azines, hydrazones, semicarbazones and oximes. The immobilization of the phthalocyanine to the walls of MCM-41 was performed by the reaction of phthalocyanine tetracarboxylic acid chloroanhydride with MCM-41 premodified by 3-(aminopropyl)-triethoxysilane (APTES). The catalytic performance of the novel AlPc-MCM-41 for hydrophosphorylation was compared with that of the same unsupported complexes.

description: Computer vision algorithms have been prevalently utilized for 3-D road imaging and pothole detection for over two decades. Nonetheless, there is a lack of systematic survey articles on state-of-the-art (SoTA) computer vision techniques, especially deep learning models, developed to tackle these problems. This article first introduces the sensing systems employed for 2-D and 3-D road data acquisition, including camera(s), laser scanners, and Microsoft Kinect. Afterward, it thoroughly and comprehensively reviews the SoTA computer vision algorithms, including (1) classical 2-D image processing, (2) 3-D point cloud modeling and segmentation, and (3) machine/deep learning, developed for road pothole detection. This article also discusses the existing challenges and future development trends of computer vision-based road pothole detection approaches: classical 2-D image processing-based and 3-D point cloud modeling and segmentation-based approaches have already become history; and Convolutional neural networks (CNNs) have demonstrated compelling road pothole detection results and are promising to break the bottleneck with the future advances in self/un-supervised learning for multi-modal semantic segmentation. We believe that this survey can serve as practical guidance for developing the next-generation road condition assessment systems.

description: Enzymatically active proteins have been isolated from the phloem of internodes of 71 Vitis species and cultivars and separated by thin layer electrofocusing. Peroxidases (EC 1.11.1.7.) yielded a pattern which could be differentiated into up to 8 bands within the pH range 6 through 11. The patterns obtained from different samples were congruent with ampelographic data, they are virtually identical within the families of Pinot and Silvaner, as weil as between haploid and diploid forms of one variety, even under different environmental conditions. American and Asian wild species and some interspecific hybrids show a slight shift of the isoelectric point of one enzyme band as compared to Vitis vinifera varieties.

description: Biochemical characterization of Vitis vinifera L. cultivars by electrophoresis of leaf isoenzymes: An attempt to classify grapevine varieties A number of 40 Vitis vinifera varieties commonly grown in France could be characterized by disc-electrophores is of isoenzymes. Starting from forced cuttings, this technique allows to ana!yze a large number of plants at any time of the year; only low quantities of leaf material are needed and no enzyme purification is necessary. Among 39 bands identified from 3 enzyme systems, 31 were variable: 19, 8 and 4 isoenzymes, respectively, of a-esterase (a-EST), glutamate oxaloacetate transaminase (GOT) and acid phosphatase (PHA). Combinations of these bands allowed to characterize each variety. 13 groups of rela ted varieties could be established by multivariate analysis of the presence versus absence of bands. The 7 best characterized groups gather varieties which, according to ampelographic classification, are grouped in the same way. The interrelations between isoenzymes and certain ampelographic characters or the presumed geographic origin of the varieties allow to propose a statistical interpretation of the enzymatic classification.

description: Multi-principal element alloys (MPEAs) continue to garner interest as structural and plasma-facing materials due to their structure stability and increased resistance to radiation damage. Despite sensitivity of mechanical behavior to irradiation and point-defect formation, there has been scant attention on understanding vacancy stability and diffusion in refractory-based MPEAs. Using density-functional theory, we examine vacancy stability and diffusion barriers in body-centered cubic (Mo0.95W0.05)0.85Ta0.10(TiZr)0.05. The results in this MPEA show strong dependence on environment, originating from local lattice distortion associated with charge-transfer between neighboring atoms that vary with different chemical environments. We find a correlation between degree of lattice distortion and migration barrier: (Ti, Zr) with less distortion have lower barriers, while (Mo, W) with larger distortion have higher barriers, depending up local environments. Under irradiation, our findings suggest that (Ti, Zr) are significantly more likely to diffuse than (Mo, W) while Ta shows intermediate effect. As such, material degradation caused by vacancy diffusion can be controlled by tuning composition of alloying elements to enhance creep strength at extreme operating temperatures and harsh conditions.

PM produced the greatest amounts of alcohol in Chardonnay juicP. fortified to 30 ° Brix followed in order by PC, S, and M, E and C. C consistently produced the least amount of alcohol. There was no significant difference in alcohol production by the first five strains at 20 ° Brix and no significant difference among the first four strains at 25 ° Brix. PM produced the highest concentrations of ethanol in YNB containing 11.1 or 12.9 % (v/v) ethanol at the time of inoculation. PC and C produced significantly less alcohol. Temperature has a profound effect on the ability of the yeast strains to grow and ferment sugar in YNB. With the exception of PM at 20 °C, none of the strains fermented the 22 % glucose completely in YNB by the end of 25 d. The higher temperature 30 °C was particularly detrimental to yeast growth and fermentation. Generally, the most complete fermentations occurred at 20 °C. PM was most tolerant of decanoic and octanoic acids.

description: White wine aging on lees in Bourgogne I. Nitrogen compounds, fatty acids and sensory ratings Nous avons comparé l'élevage traditionnel des vins de Bourgogne, en fûts de chêne et sur lie, à l'addition d'autolysats de levures. L'étude porte sur les millésimes 1982 à 1986. Les vins élevés sur lie et ceux additionnés d'autolysats de levures sont plus riches en matières azotées. Nous avons pu mettre en évidence une activité protéolytique dans ces vins e t d ans leurs lies. Les analyses sensorielles, qui n'ont porté pour l'instant que sur des vins jeu nes, font ressortir une préférence pour le vin témoin soutiré. En outre, le jury distingue la plupart des vins en début d'élevage mais ces différences s'atténuent après 2 années de conservation en bouteilles.

description: The star $β$ Pictoris harbors a young planetary system, which is characterized by the presence of a gaseous and dusty debris disk, at least two massive planets and many minor bodies. For more than thirty years, exocomets transiting the star have been detected using spectroscopy, probing the gaseous part of the cometary comas and tails. The detection of the dusty component of the tails can be performed through photometric observations of the transits. Since 2018, the Transiting Exoplanet Survey Satellite has observed $β$ Pic for a total of 156 days. Here we report an analysis of the TESS photometric data set with the identification of a total of 30 transits of exocomets. Our statistical analysis shows that the number of transiting exocomet events ($N$) as a function of the absorption depth ($AD$) in the light curve follows a power law in the form $dN(AD) \propto AD^{-α}$, where $α=2.3\pm 0.4$. This distribution of absorption depth leads to a differential comet size distribution proportional to $R^{-γ}$, where $γ=3.6 \pm 0.8$, showing a striking similarity to the size distribution of comets in the Solar system and the distribution of a collisionally relaxed population ($γ_{\rm D}= 3.5$).

description: In the midst of the COVID-19 pandemic, important transformations are taking place while a dense veil of uncertainty clouds the way out of the present predicaments. This short, impromptu comment, based on the theories of German sociologist Niklas Luhmann, plays the game of “What would Luhmann have said”, without the ambition to predict actual outcomes, but just as an exercise of interrogating his theory. Of course, Luhmann’s own brilliance would have considerably helped.

description: Formation of killer toxin by apiculate yeasts and interfernnce with fermentation Several strains of the frequently occurring apiculate yeast (Hanseniaspora uvarum) form a killer toxin (a protein) which inhibits a sensitive wine yea st (Saccharomyces cereirisiae). This toxin was partially concentrated by lyophilization and precipitation with e thanol. The toxin activity was determined with the agar diffusion method. The optimum of activity was observed at pH 4, but the killer toxin is also active at pH 3.5, the pH of grape must. The presence of apiculate killer yeasts s lowed the fermentation of a sensitive wine yeast (S. cerevisiae 381). In mixed cultures of the killer strain H. uvarum 470 with S. cerevisiae the maximum inhibition of the latter was at 20 °C and at pH 3.5. Within 2 d about 95 % of the sensitive yeast cells were killed. Several days later the wine yeast resumed fermentation. The killer toxin delayed the normal fermentation by 10- 20 d. Depending on the ratio of cell numbers between the sensitive wine yeast and the apiculate killer yeast, the fermentation was suppressed for up to 15 d. When the cell number of wine yeasts was less than 0.01 % of the killer yeast cells (H. uvarum 470) all sensitive cells were killed. Even at an inoculum of 106 cells/ml of S. cereirisiae a delay in the normal fermentation was observed when the sensitive yeast was added 2 d after the apiculate killer strain. By adding bentonite at a concentration of 0.01 % the interference of killer toxin with fermentation was prevented. The delay of normal fermentation which was caused by killer strains of H. uvarwn was not only observed in laboratory media but a lso in experiments with grape must.

description: We give an updated version of the analytical equation of state used in the Cambridge stellar evolution code (STARS) as a free to use open-source package that we have used to model cool white dwarfs down to temperatures $\log_{10}(T_\mathrm{eff}/\mathrm{K})\:=\;3$. With this update in the STARS code we model the secular evolution of cataclysmic variable (CV) stars using a double dynamo model wherein there is an interplay between two $α-Ω$ dynamos, one in the convective envelope and the other at the boundary of a slowly rotating shrinking radiative core and the growing convective envelope. We confirm that this model provides a physical formalism for the interrupted magnetic braking paradigm. In addition, our model also provides a mechanism for extra angular momentum loss below the period gap. We construct the relative probability distribution of orbital periods $P_\mathrm{orb}$ using the {mass} distribution of white dwarfs in cataclysmic variables and find that our model excellently reproduces the period gap and the observed period minimum spike in CV distribution. We also compare the evolutionary trajectories from our model with those of other empirical models and find agreement between the two. We also report good agreement between our modelled systems and observational data.

description: This study considered the mechanical properties of primary blue-stained sapwood of Norway spruce infested by the bark beetle Ips typographus. Nineteen stems from Stammerberg (ZH, Switzerland) were harvested in three different seasons and after different periods of bark beetle outbreaks. Density, Brinell hardness including elastic recovery after load, and key strength properties were tested on blue-stained wood and non-infected controls. Differences in mechanical properties were analysed according to the stand and storage time of the stems after the bark beetle attack. Spruce harvested at a late stage after the bark beetle attack (2–3 months) showed a clear reduction in impact bending strength, a significant loss in surface elastic recovery after indentation during Brinell hardness test, and a striking number of specimens with brittle fracture behaviour during Three-Point-Bending. Light microscopy and the results of the mechanical tests give clear evidence to suggest that wood-degrading fungi are already active in addition to the sap-staining fungi. Especially after larger outbreaks of bark beetles, it must be assumed that sapwood of Norway spruce does not only show the typical blue stain, but also incipient stages of wood degradation by wood-degrading fungi.

description: Eucalyptus globoidea is an emerging plantation species. Its naturally durable heartwood has the potential to be used for solid wood outdoor products. Good machinability of a timber is essential for solid wood processing but was unknown for E. globoidea. The ASTM D1666 standard was used to assess the machinability of E. globoidea and compared to that of Pinus radiata, the dominating resource for the local wood processing industry and well-known for its good machinability. This study showed that E. globoidea machined equally well or better than P. radiata in planing, boring, mortising, grooving, edging, and turning. Sanding E. globoidea (723 kg/m3) was not possible at the prescribed settings, whereas a smooth finish was obtained for the lower density P. radiata (461 kg/m3). Reducing the sanding depth resulted in a satisfactory sanding finish. Defects that determined the machine scores were identified. When boring, mortising and grooving E. globoidea timber, most defects were chipping caused by the tool exiting the piece. When edging, most care needs to be taken at the corner. The comparable machinability of E. globoidea and P. radiata according to ASTM D1666 indicated that the well-established P. radiata wood processing industry should be able to process E. globoidea.

description: A series of carbazole-based thiazole derivatives were synthesized and characterized. The title compounds were evaluated for their cytotoxicity against three cancer cell lines A549, MCF-7, and HT29 by MTT assay. Among several thiazole derivatives, compounds 4-(4-bromophenyl)-2-(2-((9-ethyl-9H-carbazol-3-yl)methylene)hydrazinyl)thiazole (3f) and 2-(2-((9-ethyl-9H-carbazol-3-yl)methylene)hydrazinyl)-4-(4-nitrophenyl)thiazole (3g) are found to display significant cytotoxicity against three cancer cell lines. These compounds have also been tested for antioxidant activity and are found to exhibit higher antioxidant activity than that of the standard BHT.
