LA SCÉNARISATION DE JEUX VIDÉO AU QUÉBEC
Authors: Arsenault Dominic , Thériault Pascale 
Published: January 2023

Cet article vise à expliciter les conditions pragmatiques dans lesquelles la scénarisation de jeux vidéo se pratique au Québec, et la réalité des métiers qui lui sont associés. En s’appuyant sur des témoignages recueillis auprès de trois praticiennes qui travaillent à la scénarisation de jeux vidéo dans des studios à Montréal, les auteur·rices décrivent la démarche de création d’un jeu vidéo, les différences entre les entreprises AAA et indépendantes, et les enjeux entourant la scénarisation selon les différents types de projets et leurs ambitions narratives. Sont abordées les différences entre conception narrative (narrative design) et écriture (writing), ainsi que les formes que prennent les documents scénaristiques pour contribuer à un « scénario » vidéoludique, terme qu’il faut repenser autant que le nom de « scénariste » pour ce médium interactif.
« DIVERSITÉ SCÉNARISTIQUE » : UNE DISCUSSION CHORALE
Authors: Tremblay Gabrielle ,   Neuf auteur·rices anonymisé·es
Published: January 2023

La scénarisation est une expérience socioprofessionnelle qui s’inscrit nécessairement dans un contexte de travail soumis à différentes dynamiques de pouvoir et d’oppression, d’inclusion et d’exclusion – tantôt volontaires, tantôt systémiques. À travers une série de fragments d’entretiens réalisés à l’automne 2021, ce texte à dix têtes investit la question de la « diversité scénaristique » dans le contexte québécois contemporain. Ce faisant, la « discussion chorale » qui se déploie au fil des pages rend compte de préoccupations actuelles et cible des pistes de réflexion peu considérées jusqu’à présent au sein des études scénaristiques au Québec.
PROJET MÉMORIAL ET POSTURES MULTIPLES
Authors: Nadeau Marie-Hélène 
Published: January 2023

Désormais exhumés des archives par la publication récente de Georges Aubin, les
Mémoires d’Amédée Papineau, fils aîné du grand Louis-Joseph, proposent un étonnant
diptyque : une première partie d’une introspection pleine de charmes, exprimée dans une
prose excellente et respectant les codes du genre mémorialiste ; une seconde, impersonnelle,
largement historiographique, où la prose laisse place à une retranscription de documents
officiels et à des entrées diaristiques en lien avec les rébellions de 1837-1838. De ce
projet mémorial se dégagent trois postures que cet article met en lumière : celle du
mémorialiste, qui permet d’inscrire le texte dans un genre en formation ; celle du
collectionneur, marquée au coin d’un sens de l’observation aiguisé et d’une forte conscience
historique se traduisant par l’importance de la conservation ; celle de l’historien,
poussant Papineau à répondre aux silences de l’Histoire. Ces trois postures analysées,
l’objet de l’oeuvre, sa destinée et son caractère curieux deviennent intelligibles et
éclairent ainsi l’entreprise narrative de Papineau au soir de sa vie.
Modeling knot features using branch scars from Mongolian oak (Quercus mongolica)
Authors: Lu Xiu-jun , Wang Lei , Gao Hui-lin , Zhan Hao , Zhang Xiao-lin 
Published: January 2023

Wood quality is an important indicator for modern sawmills. Internal wood characteristics can be derived from their correlations with external appearances. In this study, we developed linear regression models to predict knot size from surface features of Mongolian oak (Quercus mongolica) using data collected from 53 trees. For this, manual measurements and X-ray computed tomography scanning technology was respectively used to obtain internal and external features of 1,297 knots. Our results showed that Mongolian oak knots were generally concentrated in the middle part of oak stems, with fewer knots observed at the top and base. The parameters of knot and scar showed significant correlations (P < 0.01), where length and diameter of the corresponding external scar increase with increasing the length and diameter of a knot. The corresponding external scar can be used as an effective indicator to predict the internal value of oak logs. The accuracy of our constructed model is more than 95% when assessed against independent test samples. These models thus can be applied to improve the practical production of oak timber and reduce commercial loss caused by knots. These additional data can improve the estimation of the influence of knots on wood quality and provide a theoretical foundation for investigating the characteristics of hardwood knots.
Bidirectional effect of vitamin D on brown adipogenesis of C3H10T1/2 fibroblast-like cells
Authors: Mukai Takako , Kusudo Tatsuya 
Published: January 2023

Background
Brown adipose tissue (BAT) dissipates caloric energy as heat and plays a role in glucose and lipid metabolism. Therefore, augmentation and activation of BAT are the focus of new treatment strategies against obesity, a primary risk factor of metabolic syndrome. The vitamin D system plays a crucial role in mineral homeostasis, bone metabolism, and cell proliferation and differentiation. In this study, we investigated the effects of vitamin D3 [1,25(OH)2D3] on brown adipocyte differentiation.

Methods
The mouse fibroblast-like cell line C3H10T1/2 was differentiated into brown adipocytes in the presence of 1,25(OH)2D3. The effect of 1,25(OH)2D3 on brown adipocyte differentiation was assessed by measuring lipid accumulation, the expression of related genes, and cytotoxicity. The viability of C3H10T1/2 cells was measured using the Cell Counting Kit-8 assay. Gene expression was investigated using quantitative reverse transcription-polymerase chain reaction. Protein expression was estimated using western blotting.

Results
1,25(OH)2D3 inhibited adipocyte differentiation and exerted a cytotoxic effect at 1 nM. However, in the physiological concentration range (50–250 pM), 1,25(OH)2D3 promoted uncoupling protein 1 (UCP1) expression in C3H10T1/2 cells. This effect was not observed when 1,25(OH)2D3 was added 48 h after the initiation of differentiation, suggesting that the vitamin D system acts in the early phase of the differentiation program. We showed that 1,25(OH)2D3 increased the expression of two key regulators of brown adipogenesis, PR domain containing 16 (Prdm16) and peroxisome proliferator-activated receptor γ coactivator-1α (Pgc1α). Furthermore, 1,25(OH)2D3 increased Ucp1 expression in 3T3-L1 beige adipogenesis in a dose-dependent manner.

Conclusion
These data indicate the potential of vitamin D and its analogs as therapeutics for the treatment of obesity and related metabolic diseases.

Authors: Damir Rebić , Aida Hamzić-Mehmedbašić , Alen Džubur , Nermir Granov , Senad Hasanspahić 
Published: January 2023

Aims: Cardiovascular disease (CVD) is the leading cause of death in dialysis patients as well as in kidney transplant recipients (KTx). Left ventricular hypertrophy (LVH) starts early during the course of chronic kidney disease and is a strong predictor of CVD. We hypothesised that kidney transplant is significantly associated with improvement in cardiovascular reserve. We conducted a prospective study to compare changes in CV before and after kidney transplantation in patients with ESRD who received KTx to control individuals who received PD but did not receive a KTx.
Study Design: A Case-Control Study.
Place and Duration of Study: Clinic for nephrology Clinical Center University of Sarajevo, Bosnia and Herzegovina.
Methodology: In this case-control study, we included 50 KTx from the Kidney Transplant Outpatient Clinic for nephrology Clinical Center. For each 50 KTx, PD outpatients matched for gender and age were recruited. All patients underwent transthoracic echocardiography, and LV (left ventricular) mass (LVM), LV mass index (LVMi), and indices of cardiac function were measured. In the small subgroup of 18 KTx, we retrospectively assessed and compared the LVMI measurements, during dialysis and the post-transplant period.
Results: The prevalence of LVH was 24% in KTx patients and 72% in PD patients (NS). KTx had significantly lower LVM, LVMi levels, E/A ratio, FS, and LA diameter compared with the PD group, while the EF and other echocardiographic parameters did not differ. In the subgroup of 18 KTx, LVMi levels after transplantation were significantly lower than dialysis LVMi levels.
Conclusion: LVH is the most frequent cardiac abnormality at the time of kidney transplantation. After KTx, the reduction of LVH and diastolic dysfunction was significant. CV remodelling after successful KTx is related to better kidney function, and can explain better outcomes for patients with kidney transplants over patients on long-term dialysis.

Authors: Chinko Bruno Chukwuemeka , Pughikumo Dibo Tabot 
Published: January 2023

Introduction: Potash refers to the various naturally occurring water-soluble compounds of potassium used as a traditional food additive in Nigeria. Several health warnings have highlighted the deleterious effect of their consumption.
Aim: The present study is aimed at evaluating the effects of graded doses of potash consumption on haematological and hepatorenal indices using Wistar rat models.
Materials and Methods: Potash was locally sourced and the elemental composition was determined by X-Ray diffraction (XRD). Twenty (20) male Wistar rats (170 – 200g) were used for the study and were divided into four (4) groups of five (5) animals each. Group 1 served as the control while Groups 2 – 4 served as the experimental group and received an aqueous mixture of potash via oral gavage at 200, 400 and 800mg/kg respectively for thirty (30) days.
Results: XRD elemental analysis of potash revealed the presence of potassium (27.44%), phosphorus (14.27%), antimony (5.18%), barium (4.27%), fluorine (2.78%), cadmium (2.06%), yttrium (1.63%), tellurium (1.32%), caesium (1.12%), niobium (1.04%), sodium (0.42%) and germanium (0.06%). Results from haematological and hepatorenal parameters show a significant reduction in mean values of red blood cell count, haemoglobin concentration and packed cell volume among the experimental groups compared to control (p<0.05) and significantly increased mean corpuscular volume, mean corpuscular haemoglobin, white blood cell count, lymphocytes, neutrophils, MID cell percentage, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, urea, creatine, sodium, potassium and chloride ions among the experimental group compared to the control (P<0.05).
Conclusion: The data presented has shown that the chronic consumption of potash at 800mg/kg can negatively alter the haematological and hepatorenal profiles of Wistar rats. Therefore, this study considers potash, a possible toxicant to the blood, liver and kidney.

Published: January 2023

Background: Systemic analgesics should be used carefully when treating patients following renal surgery since these patients often have compromised renal function. Therefore, in such individuals, the localized nerve block may be a useful choice. This study's objective was to assess the effectiveness of transmuscular and anterior subcostal QLBs as a secure substitute for thoracic paravertebral blocks guided by ultrasonography for treating immediate postoperative pain in patients having open kidney operations.
Methods: This prospective randomized double blinded study was carried out on 54 adult patients who underwent elective open renal surgeries.
Patients were randomly classified into three equal groups, all were guided by ultrasonography: Group I: Transmuscular QLB, group II: Anterior Subcostal Quadratus Lumborum (ASQL) Block, and group III: Thoracic Paravertebral (TPV) Block.
Results: Regarding the beginning of sensory block, overall intraoperative fentanyl usage, period to first rescue analgesic demand, and overall morphine consumption, there was a substantially significant difference between the three groups (P-value <0.001). VAS revealed a substantial difference between the three groups (P<0.001) at T0 before discharging from PACU, 2, 4 and 6 hours. There was statistically significant increase in patients’ satisfaction in group II&III compared to group I where (P =0.03).
Conclusions: Ultrasound-guided anterior subcostal QLB produced safe and adequate analgesia during and after open renal surgeries that was comparable to thoracic paravertebral block, but the transmuscular QLB failed to provide adequate analgesia compared to anterior subcostal QLB and thoracic paravertebral block.

AbstractThe chelating ability of quinoxaline cores and the redox activity of organosulfide bridges in layered covalent organic frameworks (COFs) offer dual active sites for reversible lithium (Li)‐storage. The designed COFs combining these properties feature disulfide and polysulfide‐bridged networks showcasing an intriguing Li‐storage mechanism, which can be considered as a lithium–organosulfide (Li–OrS) battery. The experimental–computational elucidation of three quinoxaline COFs containing systematically enhanced sulfur atoms in sulfide bridging demonstrates fast kinetics during Li interactions with the quinoxaline core. Meanwhile, bilateral covalent bonding of sulfide bridges to the quinoxaline core enables a redox‐mediated reversible cleavage of the sulfursulfur bond and the formation of covalently anchored lithium–sulfide chains or clusters during Li‐interactions, accompanied by a marked reduction of Li–polysulfide (Li–PS) dissolution into the electrolyte, a frequent drawback of lithium–sulfur (Li–S) batteries. The electrochemical behavior of model compounds mimicking the sulfide linkages of the COFs and operando Raman studies on the framework structure unravels the reversibility of the profound Li‐ion–organosulfide interactions. Thus, integrating redox‐active organic‐framework materials with covalently anchored sulfides enables a stable Li–OrS battery mechanism which shows benefits over a typical Li–S battery.

Published: January 2023

AbstractDespite the fact that flexible temperature sensors, which can be mechanically deformed, are used for the fabrication of next‐generation smart electronics over the past few years, the improvement in their sensitivity and stability remains a major challenge. Along these lines, in this work, an all‐inorganic flexible temperature sensor consisting of MnCoNiO (MCNO) spinel structural ceramics film and a flexible 40 µm‐thick mica substrate is fabricated. By precisely controlling the production process, the pure spinel phase MCNO/mica films with low defect density can be obtained. In addition, the activation energy of the proposed flexible ceramic temperature sensor film remains stable in the natural bending state and at radii of curvature of 10, 15, and 20 mm, respectively, accordingly, B25/50 is relatively stable around the range of 3450–3550 K. Meanwhile, its sensitivity temperature coefficient of resistance value reaches −3.9% °C−1. More specifically, ΔB25/50 is less than 1.83%, 1.57%, and 1.32% after thermal shock, application of the bending cycle, and vibration, respectively. The superior performance of this all‐inorganic ceramic film is due to the excellent bonding between the film and the substrate. This work provides an alternative approach to exploit the development of the next‐generation high‐sensitivity flexible electronic devices.

Abstract2D stretchable transparent electrodes (STE) are required to conform to non‐flat complex 3D surfaces for next‐generation stretchable optoelectronic devices. However, it is a great challenge to simultaneously maintain omnidirectional stretchability, high transmittance, and the least change in conductivity at large strain. In this work, omnidirectionally stretchable 2D transparent electrode is achieved by hybrid printed copper mesh embedded in an elastic material. The electrode displays exceedingly low sheet resistance down to 0.12 Ω sq−1 while still maintaining 80% of optical transparency. Two types of mesh geometries, the horseshoe‐like and sinusoid‐like shapes, are thoroughly investigated by simulations and experiments. By optimizing the key geometrical parameters of mesh structure, the copper mesh can endure stretching up to 130% with no fractures and no resistivity change. After 1000 stretch‐and‐release cycles at 10% strain, the copper mesh remains intact with negligible resistance variation. For 2D stretchability, the copper mesh is stretched in eight directions simultaneously and can maintain its initial conductivity up to 50% tensile deformation. As a demonstration of application, the copper mesh STE is employed in a stretchable electroluminescent device that maintained uniform lighting up to 120% stretching and 100 stretch‐release cycles at 30% strain, showing its potential in stretchable and wearable optoelectronic applications.
Engineering Pt Coordination Environment with Atomically Dispersed Transition Metal Sites Toward Superior Hydrogen Evolution

Published: January 2023

AbstractMetal single‐atom (SA) catalysts have attracted immense attention due to the high catalytic efficiency given by the desired coordination environment of each metal atom. Yet, engineering the local electronic structure of SAs and multi‐atoms (MAs) still remains a challenge. Herein, an atomically dispersed catalyst comprised of Pt SAs, Pt‐Pt/V dual‐atoms, and small clusters supported on a vanadium and nitrogen co‐doped carbon (VNC) (denoted as Pt@VNC) surface is synthesized. In the Pt@VNC, both V and Pt atoms are evenly distributed on the surface of N‐doped carbon, while a few Pt atoms are linked to other Pt atoms via V, forming Pt clusters. The coordination structures of Pt atoms are modulated upon introducing atomically dispersed V sites (which generate small‐sized Pt clusters) and V2O5 clusters, showing extraordinary activity for the hydrogen evolution reaction (HER). Benefiting from the low charge transfer resistance, i.e., fast reaction kinetics, due to the synergistic effect of SAs and clusters, the Pt@VNC demonstrates superior catalytic efficiency and robust durability for the HER. It requires an overpotential of only 5 mV at a current density of 10 mA cm−2 and shows 15 times larger mass activity than the commercial 20 wt.% Pt/C catalyst. This novel catalyst‐design strategy paves a new way for maximizing catalytic efficiency by optimizing the coordination structure of metal atoms.

Published: January 2023

AbstractObjectivesWe reassess the taxonomic assignment and stratigraphic context of a permanent upper first molar and a permanent lower third premolar recovered from the archeological site of Lezetxiki in the North of the Iberian Peninsula.Materials and MethodsWe assessed the external and internal morphology of the teeth using qualitative descriptions, crown diameters, dental tissue proportions, and geometric morphometrics. The teeth from Lezetxiki were compared with Middle Pleistocene specimens, Neanderthals, Upper Paleolithic modern humans, and recent modern humans.ResultsBoth teeth were consistent with a Neanderthal classification. The upper first molar shows taurodontism, and its cusp proportions and overall morphology match those of Neanderthals. Geometric morphometric analyses of occlusal anatomy classify this molar as a Neanderthal with a posterior probability of 76%. The lower third premolar, which was originally classified as a lower fourth premolar, also shows a Neanderthal morphology. This premolar is classified as a Neanderthal with a posterior probability of 60%.DiscussionThese teeth represent the only adult Neanderthal teeth from the Western Pyrenees region found to date. The teeth were found at a stratigraphic level (designated Level III) that marks the transition level from Mousterian to Aurignacian, and are among the most recent Neanderthal remains from the north of the Iberian Peninsula.
Characterizing the changes to the material properties of a bottle‐grade poly(ethylene terephthalate) subject to repeated melt extrusion
Authors: Hatt Jonathan , Englund Karl , Li Hui 
Published: January 2023

AbstractAccording to 2018 data from the National Association of PET Container Resources, it is estimated that the recycling rate of the poly(ethylene terephthalate) (PET) bottle in the US is 29%. Trailing this figure is the amount of recycled PET bottles that are utilized for future applications, which is estimated at 20%. Over the previous decade, both values have remained relatively unchanged due to the dynamics of various factors. Ironically, one contributing factor is the mechanical recycling process itself, particularly if the material has been previously exposed. Repeated exposure to mechanical recycling can degrade the properties of the PET, limiting future utilization and in severe cases, destining the material for the landfill. Given the importance of the material properties to the proper functioning of the PET in a bottle application, it is imperative to understand how the properties of the material change when subject to repeated mechanical recycling. The aim for this research was to investigate how the properties of a virgin, bottle grade PET change when subject to a repeated step of the mechanical recycling process, melt extrusion. After each successive extrusion, changes in the thermal, rheological and mechanical properties were measured and compared to the virgin values.
An application of pulsar timing in dynamic reference frame transformation of solar system

Published: January 2023

AbstractThe establishment of pulsar space–time reference frame is of great significance for X‐ray pulsar deep space navigation. To demonstrate that the pulsar parameters are accurate enough to be used as a spatial reference, the transformation parameters, that is, α, β, and γ, of different reference frames determined based on pulsar timing are shown and compared with that of the heliocentric coordinates of Earth‐Moon barycenter. The JPL ephemerides such as DE421, DE200 and INPOP series, are mainly selected for conversion parameter calculation. For the best‐determined parameter γ, the discrepancy between the two different data is 0.38 mas/1.33σ. The timing positions of pulsars clearly show the frame‐tie of different ephemerides, indicating that MSPs have the potential to be a candidate for constructing time–space standard. It is also found that the rotation angles change linearly with time, and PSR J0437 − 4715 plays a critical role in the fitting of α. By employing a few high‐quality MSPs, the transformation precision of the right ascension is evaluated to be on the order of sub‐milliarcsecond, which is an order of magnitude higher than that of the declination.
