ASSESSMENT OF THE EFFECT OF SPEED RATIOS IN NUMERICAL SIMULATIONS OF HIGHLY VISCOUS RUBBER MIXING IN A PARTIALLY FILLED CHAMBER
Authors: Das Suma R. , Dhakal Pashupati , Poudyal Hari , Chandy Abhilash J. 
Published: August 2016

ABSTRACT
Three-dimensional, transient, isothermal, and incompressible computational fluid dynamics (CFD) simulations are carried out for rubber mixing with two counter-rotating rotors in a partially filled chamber in order to assess the effect of different speed ratios. The three different speed ratios that are investigated include 1.0, 1.125, and 1.5. In addition to the solution of the incompressible continuity and momentum equations, a Eulerian multiphase model is employed to simulate two phases, rubber and air, and the volume of fluid (VOF) technique is used to calculate the free surface flow between the phases. The Bird–Carreau model is used to characterize the non-Newtonian highly viscous rubber. Massless particles are injected in the simulations to obtain data required for statistical calculations related to dispersive and distributive mixing characteristics. Specifically, joint probability density functions of mixing index and shear rate, and cumulative distribution functions of maximum shear stress are calculated to assess dispersive mixing, while distributive mixing capabilities are evaluated using various quantities such as cluster distribution index, axial distribution, interchamber particle transfer, and segregation scale. Results showed the speed ratio 1.125 to be consistently superior to 1.5 and 1.0, in terms of both dispersive and distributive mixing performance. The large speed difference between the rotors in the case of 1.5 caused it to perform the worst.
Du pastiche imaginaire de traduction chez Raymond Queneau : le cas de On est toujours trop bon avec les femmes
Authors: Gagné Tremblay Tanka 
Published: August 2016

À la frontière des études littéraires et de la traductologie, cet article étudie la dimension pastichielle de traduction dans On est toujours trop bon avec les femmes de Raymond Queneau, prétendument traduit de l’irlandais vers le français. La présente étude cherche à déterminer comment le pseudo-traducteur s’y prend afin d’aveugler et de persuader son lecteur que le texte qu’il tient entre les mains est une véritable traduction. Le postulat repose sur la base du principe qu’il existe une corrélation entre le pastiche littéraire, qui consiste, grosso modo, à imiter à saturation le style d’un auteur singulier, et la pseudo-traduction, qui désigne un texte présenté comme s’il avait été traduit. En effet, il appert que On est toujours trop bon avec les femmes, en tant que « pastiche imaginaire », répond par essence au critère de saturation du pastiche littéraire tel que l’entend Gérard Genette. Considérant cela, il y a tout lieu de croire que la dimension « pastichielle » de cette pseudo-traduction, laissant présager qu’il y a foncièrement une véritable traduction sous-jacente, se manifeste par la mise en place d’empreintes de traduction, ou d’étrangetés, saturant le texte. La visée de cette étude est donc de révéler ces empreintes dans l’architectonique du roman, en y observant attentivement les divers éléments potentiellement saturés et conditionnels à la crédibilité du canular.

Published: August 2016

Background.Cystic fibrosis (CF) is a genetic disease that results in chronic infections of the lungs. CF patients experience intermittent pulmonary exacerbations (CFPE) that are associated with poor clinical outcomes. CFPE involves an increase in disease symptoms requiring more aggressive therapy.Methods.Longitudinal sputum samples were collected from 11 patients (n= 44 samples) to assess the effect of exacerbations on the sputum metabolome using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The data was analyzed with MS/MS molecular networking and multivariate statistics.Results.The individual patient source had a larger influence on the metabolome of sputum than the clinical state (exacerbation, treatment, post-treatment, or stable). Of the 4,369 metabolites detected, 12% were unique to CFPE samples; however, the only known metabolites significantly elevated at exacerbation across the dataset were platelet activating factor (PAF) and a related monacylglycerophosphocholine lipid. Due to the personalized nature of the sputum metabolome, a single patient was followed for 4.2 years (capturing four separate exacerbation events) as a case study for the detection of personalized biomarkers with metabolomics. PAF and related lipids were significantly elevated during CFPEs of this patient and ceramide was elevated during CFPE treatment. Correlating the abundance of bacterial 16S rRNA gene amplicons to metabolomics data from the same samples during a CFPE demonstrated that antibiotics were positively correlated toStenotrophomonasandPseudomonas, while ceramides and other lipids were correlated withStreptococcus,Rothia, and anaerobes.Conclusions.This study identified PAF and other inflammatory lipids as potential biomarkers of CFPE, but overall, the metabolome of CF sputum was patient specific, supporting a personalized approach to molecular detection of CFPE onset.

ImportanceA composite score of flavonoid-rich foods (flavodiet) may provide a clear public health message regarding the range of foods with the potential to lower dementia risk.ObjectiveTo examine associations of flavodiet score and intakes of flavonoid subclasses with dementia risk according to genetic risk and presence of depression and hypertension.Design, Setting, and ParticipantsThis prospective, population-based cohort study included dietary data from adults aged 40 to 70 years in the UK Biobank, recruited between 2006 and 2010, with a mean (SD) follow-up of 9.2 (1.5) years. The data analyses were conducted from September 1 to 30, 2023.ExposureFlavodiet score adherence and intake of flavonoid subclasses derived from 24-hour computerized dietary assessments.Main Outcome and MeasuresThe main outcome was incident all-cause dementia and interactions with genetic risk, hypertension, and depressive symptoms using multivariable Cox proportional hazards regression models.ResultsThe sample included 121 986 participants (mean [SD] age, 56.1 [7.8] years; 55.6% female; 882 with incident dementia). Comparing the highest with lowest quintile of flavodiet score, consuming 6 additional servings per day of flavonoid-rich foods was associated with a lower risk of dementia among all participants (adjusted hazard ratio [AHR], 0.72; 95% CI, 0.57-0.89), those at high genetic risk (AHR, 0.57; 95% CI, 0.42-0.78), and those with depressive symptoms (AHR, 0.52; 95% CI, 0.33-0.81) after multivariable adjustment. The greatest risk reduction was observed in participants consuming at least 2 of the following per day: 5 servings of tea, 1 serving of red wine, and 0.5 servings of berries, compared with those who did not achieve any of these intakes (AHR, 0.62; 95% CI, 0.46-0.84). Higher intakes of flavonoid subclasses, including anthocyanins, flavan-3-ols, flavonols, and flavones, of which tea, red wine, and berries are the main contributors, supported these findings, showing inverse associations with dementia risk.Conclusions and RelevanceIn this cohort study, high adherence to a flavonoid-rich diet score was associated with a lower risk of dementia, with reductions more pronounced in individuals with a high genetic risk, hypertension, and depressive symptoms. These findings suggest that simple dietary changes of increasing intakes of commonly consumed flavonoid-rich foods and drinks may lower dementia risk.

Published: September 2024

AbstractThe functionalization of zirconia surfaces by accurate and fast printing of periodical patterns embedding sub‐micrometric features is of great interest to many engineering fields and is yet to be explored. This study aims to assess the influence of the Direct Laser Interference Patterning processing parameters on the morphology and microstructure of zirconia surfaces using a 532 nm 10 ps‐pulsed laser source. Well‐defined linear structures with a period of 3 µm are successfully produced. Depending on the laser parameters, the structures are developed at or below the surface level, with higher depths (≈1 µm) being seen for increasing values of laser fluence and pulse overlap. Line‐like hierarchical structures with smaller interference spatial structures (3 µm period) and higher secondary structures with different periods (18, 15, and 12 µm) and heights (7, 5, and 3 µm, respectively) are also obtained on zirconia surface. Ablated regions presented few traces of molten material, nano‐droplets, and sub‐micrometric (<1 µm) pores, while no (sub) micrometric cracks are detected. A slight amount of tetragonal to monoclinic phase transformation (≈5%) is detected by X‐ray diffractometry. A processability map for ps‐laser processing of zirconia is proposed based on the experimental data.

AbstractIn this work, we present an organocatalytic spiroannulation method that provides access to spirocyclic benzofuran‐2‐ones. The reaction proceeds via the generation of an azolium dienolate from an α‐bromo‐α,β‐unsaturated aldehyde using a chiral N‐heterocyclic carbene, followed by annulation with benzofuran‐2‐one‐derived alkenes. The resulting chiral spirobenzofuranone‐fused cyclohexenones were obtained in 77–99% ee and dr from 1.2:1 to 20:1. The utility of the protocol was underscored by gram‐scale reaction and follow‐up transformations.

AbstractBoron clusters are applied in medicinal chemistry because of their high stability in biological environments and intrinsic ability to capture neutrons. However, their intermolecular interactions with lipid membranes, which are critical for their cellular delivery and biocompatibility, have not been comprehensively investigated. In this study, we combine different experimental methods – Langmuir monolayer isotherms at the air–water interface, calorimetry (DSC, ITC), and scattering techniques (DLS, SAXS) – with MD simulations to evaluate the impact of closo‐dodecaborate clusters on model membranes of different lipid composition. The cluster anions interact strongly with zwitterionic membranes (POPC and DPPC) via the chaotropic effect and cause pronounced expansions of lipid monolayers. The resulting lipid membranes contain up to 33 mol % and up to 52 weight % of boron cluster anions even at low aqueous cluster concentrations (1 mM). They show high (μM) affinity to the hydrophilic‐hydrophobic interface, affecting the structuring of the lipid chains, and therefore triggering a sequence of characteristic effects: (i) an expansion of the surface area per lipid, (ii) an increase in membrane fluidity, and (iii) a reduction of bilayer thickness. These results aid the design of boron cluster derivatives as auxiliaries in drug design as well as transmembrane carriers and help rationalize potential toxicity effects.

AbstractMetal hexacyanoferrates (MHCFs) with adjustable composition and open framework structures have been considered as intriguing cathode materials for sodium‐ion batteries (SIBs). Exploiting MHCFs with ultrafast and durable sodium storage capability as well as comparable capacity is always a goal that many investigators pursue, but remains challenging. Herein, simultaneous tailoring of chemical composition and morphology configuration is carried out to design a hollow monoclinic high‐entropy MHCF (HMHE‐HCF) assembled by nanocubes for the first time to realize the objective. The “cocktail effect” of high‐entropy construction, rich sodium content of monoclinic phase, and unique hollow structure endow HMHE‐HCF cathode with fast reaction kinetics and energetically stable performance during continuous charging/discharging processes. As a result, the HMHE‐HCF cathode demonstrates superior rate performance up to an ultra‐high rate of 100 C (71.1 % retention to 0.1 C), and remarkable cycling stability with a capacity retention of 77.8 % over 25,000 cycles at 100 C, outperforming most reported sodium‐ion cathodes. Further, the HMHE‐HCF//hard carbon full‐cell delivers capacities of 99.0 and 82.3 mAh g−1 at 0.1 C and 10 C, respectively, and retains 98.1 % of the initial capacity after 1,600 cycles at 5 C, demonstrating its potential application for sodium‐ion storage.

Published: September 2024

AbstractIn this study, we prepared diltiazem (DTZ)‐imprinted biomaterials for TDDS using chitosan, PVA, plasticizers, and sulfosuccinic acid. DTZ and the prepared biomaterials were characterized using field emission scanning electron microscopy, Fourier transform infrared, and 1H nuclear magnetic resonance. DTZ recognition properties were confirmed by the binding isotherm, Scatchard plot analysis, the adsorption of materials with structures similar to DTZ, selectivity factor (α), and the imprinting‐induced promotion of binding (IPB). Results revealed that adsorbed amount (Q) of DTZ‐imprinted biomaterials was 1.63–2.53 times higher than that of non‐imprinted biomaterials. In addition, it could be verified that DTZ‐imprinted biomaterials have a binding site for DTZ according to Scatchard plot analysis. Furthermore, the results of α and IPB indicated that the recognition capacity of the prepared DTZ‐imprinted biomaterials is superior to that non‐imprinted biomaterials. DTZ release properties were evaluated under various pH buffers and artificial skin. Results indicated that the DTZ release in buffers at low pH was faster than that in buffers at high pH. The DTZ release using artificial skin was continuous over 20 days. Furthermore, the DTZ release profile in the buffer followed the pseudo‐Fickian diffusion mechanism, whereas the profile in the artificial skin test followed a non‐Fickian diffusion mechanism.
Optimal quantized feedback control for linear quandratic Gaussian systems with input delay
Authors: Chen Huiling , liang Xiao , Zhang Guilin 
Published: September 2024

AbstractThis paper is concerned with the optimal quantized feedback linear quadratic Gaussian (LQG) control problem for a discrete‐time stochastic system with input delay as well as the measurements to be quantized before transmitted to the controller. In this scenario, the system is presented with several choices of quantizers, along with the cost of using each quantizer. The objective is to jointly select the quantizers and synthesize the controller to maintain an optimal balance between control performance and quantization cost. It is shown that this problem can be decoupled into two optimization problems when the innovation signal is quantized instead of state: one for optimal controller synthesis and the other for optimal quantizer selection. More specifically, a necessary and sufficient condition is derived for the optimal control problem based on Pontryagin's maximum principle. On the other hand, the optimal quantizer selection policy is established by dealing with a certain Markov decision process (MDP).

Published: September 2024

AbstractBeim Rückbau von Spannbetonbrücken wird gelegentlich aus baupraktischen Gründen angestrebt, in Herstellrichtung abzubrechen. Dadurch liegen die Trennfugen für die Abbruchtakte nicht an den bestehenden Koppelfugen und die Spannglieder müssen sich über Verbund verankern. Nach dem Durchtrennen der Spannglieder kann nicht immer von einer sofortigen vollständigen Rückverankerung ausgegangen werden. Die Bemessung der Rückbauzustände erfordert aber eine konkrete Annahme für die Verankerungslänge. Ferner ist eine Überprüfung der tatsächlich auftretenden Spaltzugkräfte im Bereich der Verbundverankerung von Interesse. Für diese Bemessung gibt es bereits Ansätze, die bisher jedoch nicht vollständig experimentell untersucht wurden. Daher wurden beim Rückbau einer Talbrücke mehrere Messungen mit faseroptischen Sensoren durchgeführt, die Aufschluss über die Dehnungsänderung beim Abbohren eines Spannglieds geben. Daraus können Informationen über die Verbundlänge und die Spannungsverteilungen im Diskontinuitätsbereich gewonnen werden. Die Ansätze für die Bemessung aus der Literatur konnten teilweise experimentell bestätigt werden. Es zeigt sich, dass bei der Bemessung sowohl globale als auch lokale Effekte berücksichtigt werden müssen, da die Verbundlänge bei gerissenen Bauteilen größer ist. Außerdem bieten sich die präsentierten faseroptischen Messlayouts auch zur Verifizierung der rechnerischen Verankerungslängen und zur Reduktion von Unsicherheiten bei einem Rückbau an.

AbstractInvolving clients in therapeutic decisions is a crucial component of effective and ethical behavior‐analytic practice. However, discrepancies between client preference for treatment options and treatment effectiveness are possible in the course of treatment. The purpose of this paper is to advance the discussion of discrepancies between client preference for treatment options and treatment effectiveness by (a) reviewing relevant considerations for adapted strategies to involve clients with limited prerequisite skills in therapeutic decisions, (b) presenting clinical data that exemplifies discrepancies between client preference for treatment options and treatment effectiveness, (c) describing nuanced considerations for navigating discrepancies, and (d) providing suggestions for future research on this topic.

AbstractMore than 20% of US youth are immigrants or the children of immigrants, and Mexicans represent the largest immigrant group. In an increasingly pluralistic society, research is needed to elucidate how risk and protective/promotive factors in immigrants' life contexts are associated with their acculturation. Within the Integrative Risk and Resilience framework, we examined the mediating role of discrimination in the association between neighbourhood diversity and acculturation strategies of 334 Mexican‐origin youth over a five‐year study (Mage = 12.80; 44.3% female). Neighbourhood diversity was computed using American Community Survey data. Perceived discrimination was self‐reported. Acculturation profiles, including transition profiles, were adopted from a previous study. Findings indicated that Mexican‐origin youth living in more diverse neighbourhoods were more likely to demonstrate an Integrated than a Moderately Assimilated profile. Over time, they were more likely to develop a Stable Integrated or Progressive than a Regressive transition profile. No mediating effect of discrimination was found. These findings imply that diverse neighbourhoods promote integrated acculturation strategies, benefiting both Mexican‐origin youth and the evolving pluralistic US society.
Investigation on Psyllium Gum as a Bio‐Based Binder for Silicon Anode in Lithium‐Ion Batteries
Authors: Cingisiz Şebnem , Arca Emin , Demir‐Cakan Rezan 
Published: September 2024

AbstractSilicon (Si) anode is of considerable interest in Li‐ion batteries due to its high theoretical capacity (4200 mAh g−1), abundant reserves in the earth, and environmentally friendly nature. Although Si anode has significant advantages, the electrode is prone to cracks due to large volume changes in its structure during discharge cycles in Li‐ion batteries. Rapid capacity degradation occurs as a result of deterioration of the structural integrity of the electrode. Although binders are known to contribute to improving the electrochemical performance of anode materials, polyvinylidene fluoride (PVdF) used in commercial Li‐ion batteries cannot maintain the mechanical stability of the Si anode during cycles due to weak Van der Waals interactions, which also dissolves in the flammable, explosive and volatile solvent N‐Methyl‐2‐pyrrolidone (NMP). In this study, low cost, sustainable and environmentally green psyllium gum (PG) was extracted from psyllium husk and tested for the first time as a water‐soluble binder for Si anode. According to galvanostatic charge/discharge tests, the Si‐PG anode exhibits a capacity of 1415 mAh g−1 after 100 cycles at a voltage range of 0.01–1.5 V and current density of C/2, which is almost 3 times higher than the Si‐PVdF anode (494 mAh g−1).
