Quand l'âme chante. La voix mélodique et son pouvoir affectif
Authors: Dakovanou Xanthoula 
Published: November 2012

Dans diverses formes de chant répandues à travers les époques et les continents, on observe un grand pouvoir d’expression affective. L’étude du chant monodique profane et sacré occidental et oriental, de l’opéra, du chant improvisé oriental et des premières polyphonies occidentales montre que la mélodie prime sur le texte quand l’expression d’une émotion pure se présente. Nous pourrions alors confirmer que la mélodie, exprimée par la voix humaine, est l’élément qui assure principalement l’expression de l’émotion dans le chant, car sinon l’homme se contenterait de la lecture d’un poème, porté par la voix parlée. Ce pouvoir d’expressivité affective provient d’un lien fort du chant avec la voix préverbale – qui est le premier lien sonore avec le premier objet – et les qualités musicales de cette voix. La première mélodie, jeu vocal-espace transitionnel du bébé aurait comme fonction de lier l’enfant à la mère, de le consoler de la séparation. Cet état de manque, voire de deuil plus tard dans la vie, ouvrirait la voie à la sublimation comme issue possible de la libido dans l’activité artistique — et quel lien serait plus opportun pour se lier à l’objet perdu que la voix, premier lien sonore avec celui-ci ? La sublimation de cette voix préverbale et fortement chargée d’émotions selon les règles sonores universelles, l’esthétique de l’époque et du compositeur nous donnerait la mélodie, porteuse de l’affect dans le chant. La combinaison avec le texte nous donnerait le chant même.
Alexandre Papadiamantis, un saint passionné
Authors: Evzonas Nicolas 
Published: November 2012

En dépit du titre du « Saint des Lettres grecques », Alexandros Papadiamantis, reconnu comme l’écrivain « national » de la Grèce moderne, se dessine à travers ses textes comme le chantre des passions et le porte-parole d’une pulsionnalité exubérante. L’article propose une exploration du dynamisme émotionnel de son œuvre axée autour de quatre thématiques : le regard clandestin hédoniste, les scénarios jaloux théâtralisant la jouissance insaisissable de l’Autre, l’Éros pour la femme privée de ses sensations recelant la peur viscérale de l’altérité et la mort récurrente des êtres féminins assimilée à des meurtres préventifs au nom de la virginité et de la stérilité.

Published: November 2012

AbstractStem cells constitute the source of differentiated cells for the generation of tissues during development, and for regeneration of tissues that are diseased or injured postnatally. In recent years, stem cell research has grown exponentially owing to the recognition that stem cell-based therapies have the potential to improve the life of patients with conditions that span from Alzheimer′s disease to cardiac ischemia to bone or tooth loss. Growing evidence demonstrates that stem cells are primarily found in niches and that certain tissues contain more stem cells than others. Among these tissues, the dental pulp is considered a rich source of mesenchymal stem cells that are suitable for tissue engineering applications. It is known that dental pulp stem cells have the potential to differentiate into several cell types, including odontoblasts, neural progenitors, osteoblasts, chondrocytes, and adipocytes. The dental pulp stem cells are highly proliferative. Collectively, the multipotency, high proliferation rates, and accessibility make the dental pulp an attractive source of mesenchymal stem cells for tissue regeneration. This review discusses fundamental concepts of stem cell biology and tissue engineering within the context of regenerative dentistry.

Abstract
Objective: The aim of this in vitro study was to evaluate the Resistance to Sliding (RS) provided by metallic brackets and 3 types of orthodontic wires (TMA, SS and NiTi), before and after the use of sodium bicarbonate airborne particle abrasion, in an experimental model with 3 non leveled brackets. Materials and Methods: The bicarbonate airborne abrasion was applied perpendicularly to the bracket slots at a distance of 2 mm, for 5 seconds (T2) and 10 seconds (T3) on each bracket slot. In a universal testing machine, the wires were pulled through a set of 3 non leveled brackets at a cross head speed of 50 mm/min for a distance of 10 mm, and static and kinetic friction readings were registered at T1 (no airborne abrasion), T2 and T3. Results: For all tested wires, a significant RS increase between T1 and T3 (P<0.001) was seen. For SS and TMA wires, there was a statistically significant RS increase between T1 and T2 (P<0.001). Between T2 and T3, RS increase was significant for TMA (P<0.001) and NiTiwires (P<0.05). Conclusions: Sodium bicarbonate air abrasive polishing during orthodontic treatment is not recommended, once this procedure promoted a significant RS increase between the metallic brackets and all the three types of wires tested.
Qualitative research on family businesses: The relevance and usefulness of the interpretive approach
Authors: Nordqvist Mattias , Hall Annika , Melin Leif 
Published: November 2012

AbstractFamily business research has grown over the last decade and there are increasing requests for deeper insights into the nature and workings of these organizations. Currently, family business research is dominated by quantitative research methods. In this article, we argue that these studies should be complemented by a research approach that is more apt to capture the specific complexity and dynamics unique to family businesses. We suggest that the interpretive approach within the broader umbrella of qualitative methods has this potential. The article discusses issues, choices, requirements and implications for family business scholars engaged in interpretive research. We also offer suggestions for how editors and reviewers can assess interpretative research.
Family business leadership transition: How an adaptation of executive coaching may help
Authors: Härtel Charmine EJ , Bozer Gil , Levin Leon 
Published: November 2012

AbstractWithin the traditional business organizational climate in which an executive coach operates, the identity of ‘the coached’ (coachee) can be quite clearly differentiated from the business identity. This is not the case within the world of family business, where the incumbent family business leader, the successor, the business and the family culture, are interwoven. This unique feature of family business means that, for executive coaching to be effective within the family business environment, a radically different approach to that used in traditional business environments must be adopted – namely, the consideration of what generally are thought of as noneconomic variables. This article represents a first attempt to effectively address the key and unique variables executive coaches need to know to work within the family business environment.

ImportanceThe optimal radiotherapy technique for unresectable locally advanced non–small cell lung cancer (NSCLC) is controversial, so evaluating long-term prospective outcomes of intensity-modulated radiotherapy (IMRT) is important.ObjectiveTo compare long-term prospective outcomes of patients receiving IMRT and 3-dimensional conformal radiotherapy (3D-CRT) with concurrent carboplatin/paclitaxel for locally advanced NSCLC.Design, Setting, and ParticipantsA secondary analysis of a prospective phase 3 randomized clinical trial NRG Oncology–RTOG 0617 assessed 483 patients receiving chemoradiotherapy (3D-CRT vs IMRT) for locally advanced NSCLC based on stratification.Main Outcomes and MeasuresLong-term outcomes were analyzed, including overall survival (OS), progression-free survival (PFS), time to local failure, development of second cancers, and severe grade 3 or higher adverse events (AEs) per Common Terminology Criteria for Adverse Events, version 3. The percentage of an organ volume (V) receiving a specified amount of radiation in units of Gy is reported as V(radiation dose).ResultsOf 483 patients (median [IQR] age, 64 [57-70] years; 194 [40.2%] female), 228 (47.2%) received IMRT, and 255 (52.8%) received 3D-CRT (median [IQR] follow-up, 5.2 [4.8-6.0] years). IMRT was associated with a 2-fold reduction in grade 3 or higher pneumonitis AEs compared with 3D-CRT (8 [3.5%] vs 21 [8.2%]; P = .03). On univariate analysis, heart V20, V40, and V60 were associated with worse OS (hazard ratios, 1.06 [95% CI, 1.04-1.09]; 1.09 [95% CI, 1.05-1.13]; 1.16 [95% CI, 1.09-1.24], respectively; all P &amp;lt; .001). IMRT significantly reduced heart V40 compared to 3D-CRT (16.5% vs 20.5%; P &amp;lt; .001). Heart V40 (&amp;lt;20%) had better OS than V40 (≥20%) (median [IQR], 2.5 [2.1-3.1] years vs 1.7 [1.5-2.0] years; P &amp;lt; .001). On multivariable analysis, heart V40 (≥20%), was associated with worse OS (hazard ratio, 1.34 [95% CI, 1.06-1.70]; P = .01), whereas lung V5 and age had no association with OS. Patients receiving IMRT and 3D-CRT had similar rates of developing secondary cancers (15 [6.6%] vs 14 [5.5%]) with long-term follow-up.Conclusions and RelevanceThese findings support the standard use of IMRT for locally advanced NSCLC. IMRT should aim to minimize lung V20 and heart V20 to V60, rather than constraining low-dose radiation bath. Lung V5 and age were not associated with survival and should not be considered a contraindication for chemoradiotherapy.Trial RegistrationClinicalTrials.gov Identifier: NCT00533949

AbstractNew‐QiangGuYin (N‐QGY), the addition of sea buckthorn on the basis of QGY formula, is herbal formula widely used clinically in China for the treatment of osteoporosis (OP), but its mechanism warrants further exploration. The mechanisms of QGY and N‐QGY in the treatment of OP are probed from the perspective of osteoclast‐osteoblast balance. Thirty Sprague‐Dawley rats are randomly divided into N‐QGY group, QGY group, and Control group. Beyond control rats that orally took normal saline, other rats are orally administered with isometric N‐QGY or QGY twice every day for 3 days. The drug‐containing serum and control serum are prepared and their effects on osteoclast‐derived exosome secretion are determined by bicinchoninic acid assay (BCA), nanoparticle tracking analysis, and Western blot. GW4869 and Interleukin‐1β (IL‐1β) are adopted as the exosome inhibitor and inducer, respectively. Exosome uptake, cell counting kit‐8, alkaline phosphatase (ALP) staining, alizarin red staining, enzyme‐linked immunosorbent assay, quantitative real‐time polymerase chain reaction, and Western blot are performed to examine the effects of altered osteoclast exosome content on osteogenic differentiation of mesenchymal stem cells (MSCs). N‐QGY, QGY, and GW4869 inhibit osteoclast‐derived exosome secretion and exosome uptake by MSCs, whereas IL‐1β exerted the opposite effects (p < 0.05). Different from IL‐1β, N‐QGY, QGY, and GW4869 partially elevated MSC viability, osteocalcin secretion, ALP, RUNX Family Transcription Factor 2 (RUNX2) and Osteopontin (OPN) expressions, and calcium deposition in the osteoclast‐MSCs coculture system (p < 0.05). Mechanically, osteoclasts increased Notum protein level but decreased β‐catenin level, which is enhanced by IL‐1β but is reversed by GW4869, QGY, and N‐QGY (p < 0.05). And the effect of N‐QGY is more conspicuous than that of QGY (P<0.05). N‐QGY‐containing serum inhibits exosome levels in osteoclasts, thereby enhancing osteogenic differentiation of MSCs via inhibition of Notum protein and promotion of β‐catenin protein.

AbstractMetal–organic frameworks (MOFs), renowned for their porous and tunable functionalities, hold significant potential for enhancing perovskite photovoltaic. However, the influence of MOF, particularly those with balanced cations in the pores, on the conversion of bottom‐layer PbI2 and the distribution of MOFs within perovskite remains underexplored. Herein, a newly synthesized Yttrium (Y)‐MOF material is introduced, featuring dimethylamine (DMA) as balanced cations within its pores and strong absorption in UV regime, to modify perovskite films. Y‐MOF, rich in oxygen and nitrogen sites, and featuring DMA within its pores, can passivate uncoordinated Pb2+ in perovskite. Scanning electron microscopy (SEM) and grazing incidence wide‐angle X‐ray scattering (GIWAXS) analysis of the top and bottom surfaces for pristine and Y‐MOF‐assisted perovskite samples reveal that the presence of PbI2 in the Y‐MOF‐assisted perovskite films is negligible. In situ UV–vis analyses demonstrate that the incorporation of Y‐MOF decelerates the crystallization kinetics of perovskite, facilitating the development of larger perovskite grains. Moreover, GIWAXS experiments conducted at different angles reveal the predominant bottom distribution of Y‐MOF within the perovskite, which effectively mitigates the impact of ultraviolet light on the perovskite. Consequently, the Y‐MOF‐assisted devices to achieve an efficiency of 24.05% with improved stability especially the UV‐light stability.

Published: June 2024

AbstractSense digitalization, the process of transforming sensory experiences into digital data, is an emerging research frontier that links the physical world with human perception and interaction. Inspired by the adaptability, fault tolerance, robustness, and energy efficiency of biological senses, this field drives the development of numerous innovative digitalization techniques. Neuromorphic bioelectronics, characterized by biomimetic adaptability, stand out for their seamless bidirectional interactions with biological entities through stimulus‐response and feedback loops, incorporating bio‐neuromorphic intelligence for information exchange. This review illustrates recent progress in sensory digitalization, encompassing not only the digital representation of physical sensations such as touch, light, and temperature, correlating to tactile, visual, and thermal perceptions, but also the detection of biochemical stimuli such as gases, ions, and neurotransmitters, mirroring olfactory, gustatory, and neural processes. It thoroughly examines the material design, device manufacturing, and system integration, offering detailed insights. However, the field faces significant challenges, including the development of new device/system paradigms, forging genuine connections with biological systems, ensuring compatibility with the semiconductor industry and overcoming the absence of standardization. Future ambition includes realization of biocompatible neural prosthetics, exoskeletons, soft humanoid robots, and cybernetic devices that integrate smoothly with both biological tissues and artificial components.

AbstractDNA serves as a model system in polymer physics due to its ability to be obtained as a uniform polymer with controllable topology and nonequilibrium behavior. Currently, a major obstacle in the widespread adoption of DNA is obtaining it on a scale and cost basis that accommodates bulk rheology and high‐throughput screening. To address this, recent advancements in bioreactor‐based plasmid DNA production is coupled with anion exchange chromatography producing a unified approach to generating gram‐scale quantities of monodisperse DNA. With this method, 1.1 grams of DNA is obtained per batch to generate solutions with concentrations up to 116 mg mL−1. This solution of uniform supercoiled and relaxed circular plasmid DNA, is roughly 69 times greater than the overlap concentration. The utility of this method is demonstrated by performing bulk rheology measurements at sample volumes up to 1 mL on DNA of different lengths, topologies, and concentrations. The measured elastic moduli are orders of magnitude larger than those previously reported for DNA and allowed for the construction of a time‐concentration superposition curve that spans 12 decades of frequency. Ultimately, these results can provide important insights into the dynamics of ring polymers and the nature of highly condensed DNA dynamics.

AbstractThe disordered phase of spinel LiMn1.5Ni0.5O4 (LNMO) is more appealing as high‐voltage cathode due to its superior electrochemical performance compared to its ordered counterpart. Various methods are developed to induce a phase transition. However, the resulting materials often suffer from capacity degradation due to the adverse influence of accompanying Mn3+ ions. This study presents the utilization of local magnetic fields generated by a magnetic Fe3O4 shell to induce a disordered phase transition in LNMO at lower temperature, transitioning it from an order state without significantly increasing the Mn3+ content. The pivotal role played by the local magnetic fields is evidenced through comparisons with samples with nonmagnetic Al2O3 shell, samples subjected to sole heat treatment, and samples heat‐treated within magnetic fields. The key finding is that magnetic fields can initiate a radical pair mechanism, enabling the induction of order‐disorder phase transition even at lower temperatures. The disordered spinal LNMO with a magnetic Fe3O4 shell exhibits excellent cycling stability and kinetic properties in electrochemical characterization as a result. This innovation not only unravels the intricate interplay between the disordered phase and Mn3+ content in the cathode spinel but also pioneers the use of magnetic field effects for manipulating material phases.

AbstractCarbon nanotubes (CNTs) are in great demand in many fields because of their unique properties such as high conductivity, chemical stability, lightweight, and high strength. They also received much attention in optical‐related fields because of the super‐black characteristics under visible light and the photothermal effect of infrared light. Recently, the coloration of CNTs under visible light is realized by a simple liquid phase method with the help of silica photonic crystal (PC) coatings. However, the response modulation such as the photoluminescence (PL) property of CNTs to the infrared and ultraviolet (UV) bands is not yet studied. Herein, silane functionalized carbon dots (SiCDs) are introduced into silica PCs, and successfully realized the structural coloration and PL of CNT fibers (CNTFs). The optical and fluorescence visualization of single CNTs and suspended CNT networks (SCNTNs) is also realized with the assistance of SiCDs droplets. These SiCDs‐decorated SiPCs‐coated CNTFs (SiCDs@SiPCs‐CNTFs) exhibit an up/down‐conversion PL response, and the excitation light source can be UV light, visible light, and near‐infrared laser. The structural coloration and the development of new PL properties will promote the wide applications of PL carbon hybrid materials in many fields such as smart displays, intelligent textiles, anti‐counterfeiting, etc.

AbstractINTRODUCTIONThere is limited evidence about factors related to the timeliness of dementia diagnosis in healthcare settings.METHODSIn five prospective cohorts at Rush Alzheimer's Disease Center, we identified participants with incident dementia based on annual assessments and examined the timing of healthcare diagnoses in Medicare claims. We assessed sociodemographic, health, and psychosocial correlates of timely diagnosis.RESULTSOf 710 participants, 385 (or 54%) received a timely claims diagnosis within 3 years prior to or 1 year following dementia onset. In logistic regressions accounting for demographics, we found Black participants (odds ratio [OR] = 2.15, 95% confidence interval [CI]: 1.21 to 3.82) and those with better cognition at dementia onset (OR = 1.48, 95% CI: 1.10 to 1.98) were at higher odds of experiencing a diagnostic delay, whereas participants with higher income (OR = 0.89, 95% CI: 0.81 to 0.97) and more comorbidities (OR = 0.94, 95% CI: 0.89 to 0.98) had lower odds.DISCUSSIONWe identified characteristics of individuals who may miss the optimal window for dementia treatment and support.Highlights
We compared the timing of healthcare diagnosis relative to the timing of incident dementia based on rigorous annual evaluation.
Older Black adults with lower income, higher cognitive function, and fewer comorbidities were less likely to be diagnosed in a timely manner by the healthcare system.
