Maîtriser le Chat (ro)botté ou comment soumettre l’intelligence artificielle au service de nos usagers en milieu universitaire ?
Authors: Bascik Teresa , Pham-Dang Stéphanie 
Published: September 2024

L’article explore la métaphore du Chat botté pour décrire les agents conversationnels animés par l’intelligence artificielle, en particulier les chatbots comme ChatGPT d’OpenAI. Ces outils utilisent le langage naturel pour simuler des conversations humaines et peuvent s’avérer pertinents dans les bibliothèques universitaires pour des tâches comme la création de métadonnées et le service de référence, ainsi que l’offre de formations. L’étude aborde une approche d’apprentissage interactif par interactivité avec ces technologies, mettant en évidence à la fois leur potentiel et leurs limites, notamment leur tendance à générer des « hallucinations » informatives sans fondement dans la réalité. Les compétences requises pour intégrer efficacement ces outils dans les pratiques professionnelles des bibliothécaires en milieu universitaire sont discutées, tout comme l’importance de comprendre et de maîtriser les requêtes (« prompts » en anglais) pour obtenir des réponses utiles et précises.
Analyse qualitative du vécu des emprunteurs et des non-emprunteurs de livres à BAnQ et à d’autres bibliothèques publiques
Authors: Luckerhoff Jason , Lapointe Marie-Claude 
Published: September 2024

Dans leur portrait des emprunteurs de livres numériques (LN) au sein de Bibliothèque et Archives nationales du Québec (BAnQ), Lapointe, Luckerhoff et Niort (2023) les ont comparés aux emprunteurs de livres physiques (LP) et aux emprunteurs hybrides. L’exercice a permis de dégager des tendances et de soulever des questions, notamment : quel est le vécu des emprunteurs de LP qui font la transition vers le LN ? Comment se déroulent les expériences d’emprunts ? Quel sens les emprunteurs donnent-ils à la bibliothèque en tant que lieu ? Dans le cadre de la recherche dont fait état le présent article, nous avons animé plus de 70 entretiens individuels et de groupe auprès d’emprunteurs et de non-emprunteurs de BAnQ et d’autres bibliothèques publiques afin de mieux comprendre leur vécu à l’égard des LP et des LN, des lieux du livre comme la bibliothèque publique — y compris la Grande Bibliothèque de BAnQ —, leurs perceptions de l’ensemble de ces réalités ainsi que leurs expériences d’emprunts.
Dynamic response of the Black Sea elevation to intraseasonal fluctuations of the Mediterranean sea level
Authors: Volkov Denis L. , Johns William E. , Belonenko Tatyana V. 
Published: December 2015

AbstractResponse of the Black Sea elevation to intraseasonal sea level changes in the Mediterranean is studied using satellite altimetry data and a linear analytical model. Satellite observations show that the nonseasonal sea level in the Black Sea (η1) is coherent with that in the Aegean and Marmara Seas (η0) but lags behind them by 10–40 days at subannual periods. The observed time lag is mainly due to friction that constrains the exchange through the Bosphorus Strait. Using realistic friction and characteristic η0 forcing in the model, we find that the amplitude of η1 reaches the amplitude of η0 at about 1 year period, and the time lag increases from 10 to 22 days at periods 50–250 days. Freshwater fluxes, atmospheric pressure, and to a smaller extent the along‐strait wind also influence the Black Sea elevation, but sea level fluctuations in the Mediterranean appear to be the dominant forcing mechanism.
Eine biokatalytische Kaskade für die vielseitige Eintopf‐Modifizierung von mRNA ausgehend von Methioninanaloga
Authors: Muttach Fabian , Rentmeister Andrea 
Published: December 2015

AbstractMethyltransferasen sind nützlich, um funktionelle Gruppen ortsspezifisch in Biomoleküle einzubauen, wenn Analoga des Kosubstrates S‐Adenosyl‐l‐Methionin (AdoMet) verfügbar sind. Methyltransferasen wurden eingesetzt, um RNA‐Moleküle selektiv und ortsspezifisch zu adressieren, was für biophysikalische und mechanistische Studien sowie die Markierung in der komplexen zellulären Umgebung unerlässlich ist. AdoMet‐Analoga sind jedoch nicht zellgängig, sodass diese Strategie nicht in Zellen anwendbar ist. Wir präsentieren eine zweistufige enzymatische Kaskade zur ortsspezifischen mRNA‐Modifizierung ausgehend von Methioninanaloga. Unser Ansatz kombiniert die enzymatische Synthese von AdoMet mit der Modifikation der 5′‐Kappe durch eine spezifische mRNA‐Methyltransferase in einem Eintopfverfahren. Wir zeigen, dass eine Reihe von Substraten, unter anderem mit Alken‐, Alkin‐ und Azidoresten, eingesetzt werden kann und dass die weitere Derivatisierung mit Klick‐Reaktionen gelingt.
A Graphene Fibriform Responsor for Sensing Heat, Humidity, and Mechanical Changes
Authors: Zhao Fei , Zhao Yang , Cheng Huhu , Qu Liangti 
Published: December 2015

AbstractControllable and sensitive perception of environmental changes is essential for the development of smart material and device systems. Herein, a multi‐stimuli sensitive responsor has been fabricated on the base of the established double‐helix core‐sheath graphene‐based microfibers (GFs). By combining the tunable conductivity and mechanical robustness of GF coated with graphitic carbon nitride (GF@GCN), a fibriform smart environmental responsor (SER) is prepared by water‐assisted GFs‐twisting strategy, which can accordingly present conductive state‐dependent current responses upon exposure to a variety of stimuli. More importantly, this SER exhibits high current response to small perturbations induced by temperature variations, mechanical interactions, and relative humidity changes, thereby achieving an environmental perceptibility. Based on this finding, a multi‐functional respiratory monitor has been built under the stimuli of the human breath.
Reversible Guest Uptake/Release by Redox‐Controlled Assembly/Disassembly of a Coordination Cage
Authors: Croué Vincent , Goeb Sébastien , Szalóki György , Allain Magali , Sallé Marc 
Published: December 2015

AbstractControlling the guest expulsion process from a receptor is of critical importance in various fields. Several coordination cages have been recently designed for this purpose, based on various types of stimuli to induce the guest release. Herein, we report the first example of a redox‐triggered process from a coordination cage. The latter integrates a cavity, the panels of which are based on the extended tetrathiafulvalene unit (exTTF). The unique combination of electronic and conformational features of this framework (i.e. high π‐donating properties and drastic conformational changes upon oxidation) allows the reversible disassembly/reassembly of the redox‐active cavity upon chemical oxidation/reduction, respectively. This cage is able to bind the three‐dimensional B12F122− anion in a 1:2 host/guest stoichiometry. The reversible redox‐triggered disassembly of the cage could also be demonstrated in the case of the host–guest complex, offering a new option for guest‐delivering control.
A Biocatalytic Cascade for Versatile One‐Pot Modification of mRNA Starting from Methionine Analogues
Authors: Muttach Fabian , Rentmeister Andrea 
Published: December 2015

AbstractMethyltransferases have proven useful to install functional groups site‐specifically in different classes of biomolecules when analogues of their cosubstrate S‐adenosyl‐l‐methionine (AdoMet) are available. Methyltransferases have been used to address different classes of RNA molecules selectively and site‐specifically, which is indispensable for biophysical and mechanistic studies as well as labeling in the complex cellular environment. However, the AdoMet analogues are not cell‐permeable, thus preventing implementation of this strategy in cells. We present a two‐step enzymatic cascade for site‐specific mRNA modification starting from stable methionine analogues. Our approach combines the enzymatic synthesis of AdoMet with modification of the 5′ cap by a specific RNA methyltransferase in one pot. We demonstrate that a substrate panel including alkene, alkyne, and azido functionalities can be used and further derivatized in different types of click reactions.
Potential job creation in the cellulosic biofuel industry: the effect of feedstock price
Authors: Kim Seungdo , Dale Bruce E. 
Published: December 2015

AbstractA large‐scale biofuel industry based on cellulosic materials would provide many new job opportunities. We model potential direct jobs generated by a cellulosic ethanol industry in the United States. These job projections are estimated via a bottom‐up approach based on the cellulosic feedstock supply chain systems as a function of the price farmers receive for the feedstock. The cellulosic feedstock types involved in the feedstock supply chain system are crop residues, perennial grasses, annual energy crops, and coppiced and non‐coppiced woody crops. Results show that the feedstock transportation sector is where most of the jobs are created, followed by the feedstock production sector. Jobs generated by the feedstock transportation sector account for around one‐third of total new jobs generated, while jobs generated by cellulosic feedstock production account for about one‐quarter of the new jobs. In the United States, most of the new jobs are created in Iowa, Kansas, Missouri, Oklahoma, and Texas. At feedstock prices over US$ 55 per dry ton, more than 100 000 new direct full‐time equivalent jobs are potentially generated. The number of jobs potentially generated by the cellulosic ethanol fuel production system is highly sensitive to the feedstock price. At $60 per ton, a 50% increase in feedstock price, the system generates over 6 times more jobs than it does at a feedstock price of $40 per ton. Many more farmers produce cellulosic feedstock for ethanol production at higher feedstock prices, and thus more ethanol production leads to more job creation. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd
Simulation studies of substrate recognition by the exocellulase CelF from Clostridium cellulolyticum
Authors: Chen Mo , Himmel Michael E. , Wilson David B. , Brady John W. 
Published: December 2015

ABSTRACTMolecular dynamics (MD) simulations were used to study substrate recognition by the family 48 exocellulase CelF from Clostridium cellulolyticum. It was hypothesized that residues around the entrance of the active site tunnel of this enzyme might serve to recognize and bind the substrate through an affinity for the cellulose monomer repeat unit, β‐d‐glucopyranose. Simulations were conducted of the catalytic domain of this enzyme surrounded by a concentrated solution of β‐d‐glucopyranose, and the full three‐dimensional probability distribution for finding sugar molecules adjacent to the enzyme was calculated from the trajectory. A significant probability of finding the sugar stacked against the planar faces of Trp 310 and Trp 312 at the entrance of the active site tunnel was observed. Biotechnol.

Effects of Geometrical Parameters on the Pressure Drop for a Modified Cyclone Separator
Authors: Tan Fuat , Karagoz Irfan , Avci Atakan 
Published: December 2015

AbstractExperimental results for a conventional cyclone and a modified cyclone with an adjustable vortex stopper are presented. The modified design is based on the idea of decreasing the surface friction by leaving a separation space between the cylindrical part and the vortex stopper. The measured pressure losses were compared for various exit pipe diameters, cylinder heights, cone bottom diameters, and inlet velocities for the conventional as well as for the modified design. The comparative studies indicate a similar behavior of the pressure loss coefficient for both cyclones. Additionally, the exit pipe diameter has a more significant effect on both cyclones compared to the other parameters. Increasing the length of the cyclone reduced the pressure losses for all cases examined.
Direct Synthesis of an α,ω‐Diester from 2,7‐Octadienol as Bulk Feedstock in Three Tandem Catalytic Steps
Authors: Ostrowski Karoline A. , Vogelsang Dennis , Seidensticker Thomas , Vorholt Andreas J. 
Published: December 2015

AbstractA new tandem catalytic process was designed and developed as a tool for the direct conversion of the widely available feedstock 2,7‐octadienol into an α,ω‐diester. This innovative auto‐tandem catalysis is atom efficient and consists of three consecutive palladium‐catalysed reactions: ether formation, ether carbonylation and alkoxycarbonylation. By using the design of experiments (DoE) approach, significant parameters were determined and the yield of the desired α,ω‐diester was optimised. Model substrates allowed deeper insight into the progress of the reaction to be gained and, as a result, the reaction sequence was uncovered. Furthermore, by simply applying other ligands, a different reaction path was followed, allowing other, new tandem catalytic sequences to be explored and enabling new compounds to be obtained.
Rational Design for Complementary Donor–Acceptor Recognition Pairs Using Self‐Complementary Hydrogen Bonds
Authors: Sikder Amrita , Ghosh Boyli , Chakraborty Saptarshi , Paul Ankan , Ghosh Suhrit 
Published: December 2015

AbstractAn adaptable and efficient molecular recognition pair has been established by taking advantage of the complementary nature of donor–acceptor interactions together with the strength of hydrogen bonds. Such distinct molecular recognition propagates in orthogonal directions to effect extended alternating co‐assembly of two different appended molecular entities. The dimensions of the assembled structures can be tuned by stoichiometric imbalance between the donor and acceptor building blocks. The morphology of the self‐assembled material can be correlated with the ratio of the two building blocks.
Linear Tetraphenylmethane‐Based Thioether Oligomers Stabilising an Entire Gold Nanoparticle by Enwrapping
Authors: Lehmann Mario , Peters Erich Henrik , Mayor Marcel 
Published: December 2015

AbstractThe design and synthesis of a novel linear thioether‐based ligand subunit with a tetraphenylmethane core used in the stabilisation of gold nanoparticles (AuNPs) are presented. Mono‐, tri, penta‐ and heptamers of the ligand have been synthesised and used to stabilise AuNPs by enwrapping. With the exception of the monomer, all ligands provide reliable long‐term stability and redispersibility for the coated nanoparticles in common organic solvents. Despite variation of the oligomer length, all stable particles were of the same size within error tolerance (1.16±0.32 nm for the trimer, 1.15±0.30 nm for the pentamer, 1.17±0.34 nm for the heptamer), as investigated by transmission electron microscopy (TEM). These findings suggest that not only the number of sulfur atoms in the ligand, but also its bulkiness play a crucial role in stabilising the AuNPs. These findings are supported by thermogravimetric analysis (TGA), showing that AuNPs stabilised by the penta‐ or heptamer are passivated by a single ligand. Thermal stability measurements suggest a correlation between ligand coverage and thermal stability, further supporting these findings.

A boundary integral method for computing forces on particles in unsteady Stokes and linear viscoelastic fluids

Published: December 2015

SummaryAccurately characterizing the forces acting on particles in fluids is of fundamental importance for understanding particle dynamics and binding kinetics. Conventional asymptotic solutions may lead to poor accuracy for neighboring particles. In this paper, we develop an accurate boundary integral method to calculate forces exerted on particles for a given velocity field. We focus our study on the fundamental two‐bead oscillating problem in an axisymmetric frame. The idea is to exploit a correspondence principle between the unsteady Stokes and linear viscoelasticity in the Fourier domain such that a unifying boundary integral formulation can be established for the resulting Brinkman equation. In addition to the dimension reduction vested in a boundary integral method, our formulation only requires the evaluation of single‐layer integrals, which can be carried out efficiently and accurately by a hybrid numerical integration scheme based on kernel decompositions. Comparison with known analytic solutions and existing asymptotic solutions confirms the uniform third‐order accuracy in space of our numerical scheme. Copyright © 2016 John Wiley & Sons, Ltd.
Reliability Evaluation of an Open‐Cathode PEMFC at Operating State and Longtime Vibration by Mechanical Loads
Authors: Imen S. J. , Shakeri M. 
Published: December 2015

AbstractReliability and durability of proton exchange membrane fuel cells (PEMFCs) are one of the most complex issues in real applications' environment. Especially, when it subjects to the various mechanical loads and vibrations. This topic requires more attention for research and experimental works. In this study, the effect of mechanical loads was investigated on an open‐cathode PEMFC in operating state. Several long time vibration tests have been applied on non‐operating PEMFC, and the performance of the fuel cell was evaluated during the test. Hydrogen leakage as a key parameter was investigated in performance monitoring instead of measuring torque on compression bolts. The vibration tests were consisted of sine, shock and random for X, Y and Z axes in operating state and random vibration in non‐operating state of PEMFC. The experimental results in operating state were indicated that the fuel cell performance has not been affected by the proposed vibrations. Furthermore, the test results of non‐operating state have been shown that the performance of PEMFC reduces about 0.6% in each four‐hour step of the vibration test. In addition, the experiments reveal that if the mechanical loads and vibrations cause physical damage on the fuel cell components, they can change the performance and reliability of the fuel cell.
