Rituel corybantique des mystères socratiques et doctrine des principes
Authors: Périllié Jean-Luc 
Published: September 2019

L’objet de cet article est de proposer une nouvelle grille d’interprétation du dialogue énigmatique de Platon, nommé Euthydème : il s’agit très probablement d’un dialogue crypté de type initiatique. Toutefois, l’auteur n’a pas laissé le lecteur totalement sans ressources. Quatre clés peuvent être détectées : 1) Similitude dramatique avec les Nuées d’Aristophane, pièce qui représente l’initiation de Strepsiade ; 2) Mention explicite d’un rite initiatique de type corybantique (277e) ; 3) Aporie centrale du dialogue comme indice des limites de l’accompagnement de Socrate ; 4) Il est dit que les sophistes n’étaient pas un mais deux (271a). Cette dernière clé nécessite cependant, pour être utilisée, que le lecteur connaisse la doctrine des Principes de l’enseignement oral de Platon. Si on actionne les quatre clés, les différentes énigmes du dialogue se clarifient les unes après les autres. L’Euthydème est un dialogue central traitant de l’initiation, selon deux objectifs principaux : a) Reprise globale de la fonction apologétique des Dialogues consistant à rétablir la vérité de l’accompagnement socratique, comme rite initiatique selon le modèle du corybantisme ; b) Montrer comment les Mystères socratiques doivent être prolongés par les Mystères platoniciens, ceux-ci parvenant à la contemplation des Principes ultimes de la Monade et de la Dyade indéfinie. Qui plus est, en appliquant cette nouvelle grille de lecture, l’Euthydème permet de voir comment se coordonnent le Banquet, la République et le Théétète, relativement aux Premiers dialogues.

Published: September 2019

Background Chronic non-communicable diseases (CNCDs) are increasing with grave consequences to countries’ development. The purpose of this study was three-fold: (1) to determine challenges PURE study participants faced regarding CNCD interventions and what they required from a CNCD intervention programme, and (2) to explore courses of action Department of Health (DoH) officials thought would perform best, as well as (3) to determine what DoH officials perceive to be obstacles in addressing the CNCD epidemic. Design and methods A subsample of 300 participants from the Prospective Urban and Rural Epidemiological study's Western Cape urban cohort and six key officers from the DoH were recruited to participate in this cross-sectional study. Questionnaires were used in face-to-face interviews with the PURE study participants and DoH officials, together with the multi-criteria mapper (MCM) interviewing method with the latter. Results Most PURE participants were overweight/obese, but not keen to participate in weight loss interventions. They sought education on foods associated with weight gain, shopping lists, cooking lessons and recipes from CNCD intervention programmes. Department of Health officials regarded the integration of health services, community participation, amongst others as the most favourable options to address the CNCD epidemic. Conclusions The integration of health services, community participation, food taxation and improving inter-sectoral partnerships were viewed as the most feasible options to address the CNCD epidemic according to the DoH officials. At community level, the needs for education and practical hints were expressed. Current CNCD interventions should be adapted to include the context-based needs of communities.

Published: September 2019

Context
Fear of reinjury after an anterior cruciate ligament (ACL) reconstruction (ACLR) may be associated with persistent deficits in knee function and subsequent injury. However, the effects of negative emotion on neuromuscular-control strategies after an ACL injury have remained unclear.

Objective
To identify how negative emotional stimuli affect neural processing in the brain and muscle coordination in patients after anterior cruciate ligament reconstruction compared with healthy control participants.

Design
Case-control study.

Setting
Neuromechanics laboratory.

Patients or Other Participants
Twenty patients after unilateral anterior cruciate ligament reconstruction and 20 healthy recruits.

Main Outcome Measure(s)
Electrocortical θ (4–8 Hz) activity (event-related synchronization, % increased power relative to a nonactive baseline) at selected electrodes placed at the frontal (F3, Fz, F4) and parietal (P3, Pz, P4) cortices using electroencephalography, neurophysiological cardiac changes (beats/min), and subjective fear perceptions were measured, along with joint stiffness (Nm/°/kg) with and without an acoustic stimulus in response to 3 types of emotionally evocative images (neutral, fearful, and knee-injury pictures).

Results
Both groups had greater frontoparietal θ power with fearful pictures (Fz: 35.9% ± 29.4%; Pz: 81.4% ± 66.8%) than neutral pictures (Fz: 24.8% ± 29.7%, P = .002; Pz: 64.2 ± 54.7%, P = .024). The control group had greater heart-rate deceleration with fearful (−4.6 ± 1.4 beats/min) than neutral (−3.6 ± 1.3 beats/min, P &lt; .001) pictures, whereas the ACLR group exhibited decreased heart rates with both the fearful (−4.6 ± 1.3 beats/min) and injury-related (−4.4 ± 1.5 beats/min) pictures compared with neutral pictures (−3.4 ± 1.4 beats/min, P &lt; .001). Furthermore, during the acoustic startle condition, fearful pictures increased joint stiffness (Nm/°/kg) in the ACLR group at the midrange (0°–20°: 0.027 ± 0.02) and long range (0°–40°: 0.050 ± 0.02) compared with the neutral pictures (0°–20°: 0.017 ± 0.01, P = .024; 0°–40°: 0.043 ± 0.02, P = .014).

Conclusions
Negative visual stimuli simultaneously altered neural processing in the frontoparietal cortices and joint-stiffness regulation strategies in response to a sudden perturbation. The adverse effects of fear on neuromuscular control may indicate that psychological interventions should be incorporated in neuromuscular-control exercise programs after ACL injury.
Youth suicide in New South Wales: urban‐rural trends
Authors: Dudley Michael , Waters Brent , Kelk Norman , Howard John 
Published: September 2019

ObjectiveThe study tested the hypotheses that (i) the rate of suicide by firearms among youth (aged 10‐19 years) is increasing at a greater rate than rates of suicide by other methods; (ii) the rate of youth suicide in rural New South Wales is significantly higher than those in urban areas; and (iii) the increase in youth suicide by means of firearms is occurring at a greater rate in rural males aged 15‐19 years than in other groups.DesignData were obtained from the NSW Office of the Australian Bureau of Statistics concerning 735 youth suicides in NSW between 1964 and 1988. These were reviewed for information concerning residential area and method of death. Five five‐year periods were used, and rates were calculated with population figures obtained in the census years for the same age and sex group.ResultsFrom 1964 to 1988, suicide by firearms has risen most substantially, from 3.4 to 5.6 per 100 000 per year in 15‐19‐year‐old males. There has also been a substantial increase in 15‐19‐year‐old male suicides by hanging (0.7 to 3.4 per 100 000 per year). Poisoning suicides have declined among females and males in the past 15 years. Suicide rates in Sydney, Newcastle and Wollongong have remained stable. In rural cities, they have increased from 1.5 to 4.7 per 100 000 per year (F = 4.9, P< 0.02) while in rural municipalities and shires they have increased from 1.3 to 6.4 (F = 14.6, P<0.0001). The suicide rate of 15‐19‐year‐old males has shown a modest increase in Sydney and no change in Newcastle or Wollongong, but the rate for 15‐19‐year‐old males in rural cities has more than doubled, from 5.1 to 12.5 (F = 7.7, P< 0.003), while in rural municipalities and shires, the rate has increased more than fivefold, from 3.9 to 20.7 (F = 9.3, P< 0.001). There has been no significant change in the suicide rates of 15‐19‐year‐old females, or in 10‐14‐year‐olds. The rate of suicide by firearms among 15‐19‐year‐old males has not risen significantly in rural cities, but in rural municipalities and shires the rates have risen fivefold from 2.8 to 14.8 (F = 5.6, P<0.01).ConclusionsEach hypothesis was confirmed. An increase of this magnitude is not an artefact of coroners' verdicts. The findings are believed to be due to ready access to firearms, the use of alcohol and drugs (particularly in firearms suicides) and increasing socioeconomic, health, and identity problems for rural youth, especially males.

ObjectiveTo determine the short‐term and long‐term results of percutaneous aortic valvuloplasty.DesignA retrospective follow‐up study.SettingThe Cardiac Catheterisation Laboratory and Cardiovascular Medicine Unit of a teaching hospital.PatientsEighteen patients with severe aortic stenosis who were not accepted for surgery; there were 11 men and 7 women, mean age 79 ±4.5 years.InterventionsPercutaneous transluminal aortic valvuloplasty (PTAV) by means of balloon catheter techniques.Main outcome measuresPatient survival and symptomatic status.ResultsPTAV resulted in a significant decrease in the aortic valve pressure gradient from 64.8 ±23.2 mmHg to 38 ±14.7 mmHg (mean±SD) (P<0.00001) in the 18 patients and a significant increase in the mean aortic valve area from 0.4±0.16 cm1 to 0.6±0.18 cm2 (P<0.0001) in 14 patients. Complications occurred in seven patients; two of them, who had been in terminal heart failure with a low output state before PTAV, died. Fifteen patients improved in at least one New York Heart Association functional class early after PTAV and one patient had an aortic valve replacement. In follow‐up of between 5 and 32 months (mean, 13.3 ±7.7 months) six patients are in a better functional class than before PTAV, one patient is in Class IV, one patient had an aortic valve replacement and seven patients died (three died of cardiac failure and four of non‐cardiac causes).ConclusionsPTAV has a place as a palliative procedure in selected patients with aortic stenosis in whom another condition precludes aortic valve replacement.

AbstractIn this work, for the first time, the addition of aluminum oxide nanostructures (Al2O3 NSs) grown by glancing angle deposition (GLAD) is investigated on an ultrathin Cu(In,Ga)Se2 device (400 nm) fabricated using a sequential process, i.e., post‐selenization of the metallic precursor layer. The most striking observation to emerge from this study is the alleviation of phase separation after adding the Al2O3 NSs with improved Se diffusion into the non‐uniformed metallic precursor due to the surface roughness resulting from the Al2O3 NSs. In addition, the raised Na concentration at the rear surface can be attributed to the increased diffusion of Na ion facilitated by Al2O3 NSs. The coverage and thickness of the Al2O3 NSs significantly affects the cell performance because of an increase in shunt resistance associated with the formation of Na2SeX and phase separation. The passivation effect attributed to the Al2O3 NSs is well studied using the bias‐EQE measurement and J–V characteristics under dark and illuminated conditions. With the optimization of the Al2O3 NSs, the remarkable enhancement in the cell performance occurs, exhibiting a power conversion efficiency increase from 2.83% to 5.33%, demonstrating a promising method for improving ultrathin Cu(In,Ga)Se2 devices, and providing significant opportunities for further applications.

AbstractThis work demonstrates a stretchable and flexible lactate/O2 biofuel cell (BFC) using buckypaper (BP) composed of multi‐walled carbon nanotubes as the electrode material. Free‐standing BP, functionalized with a pyrene‐polynorbornene homopolymer, is fabricated as the immobilization matrix for lactate oxidase (LOx) at the anode and bilirubin oxidase at the cathode. This biofuel cell delivers an open circuit voltage of 0.74 V and a high‐power density of 520 µW cm−2. The functionalized BP electrodes are assembled onto a stretchable screen‐printed current collector with an “island–bridge” configuration, which ensures conformal contact between the wearable BFC and the human body and endows the BFC with excellent performance stability under stretching condition. When applied to the arm of the volunteer, the BFC can generate a maximum power of 450 µW. When connected with a voltage booster, the on‐body BFC is able to power a light emitting diode under both pulse discharge and continuous discharge modes during exercise. This demonstrates the promising potential of the flexible BP‐based BFC as a self‐sustained power source for next‐generation wearable electronics.
New Light on Molecule–Nanotube Hybrids
Authors: Chen Yani , Marty Laëtitia , Bendiab Nedjma 
Published: September 2019

AbstractOptoelectronics benefits from outstanding new nanomaterials that provide emission and detection in the visible and near‐infrared range, photoswitches, two level systems for single photon emission, etc. Among these, carbon nanotubes are envisioned as game changers despite difficult handling and control over chirality burdening their use. However, recent breakthroughs on hybrid carbon nanotubes have established nanotubes as pioneers for a new family of building blocks for optics and quantum optics. Functionalization of carbon nanotubes with molecules or polymers not only preserves the nanotube properties from the environment, but also promotes new performance abilities to the resulting hybrids. Photoluminescence and Raman signals are enhanced in the hybrids, which questions the nature of the electronic coupling between nanotube and molecules. Furthermore, coupling to optical cavities dramatically enhances single photon emission, which operates up to room temperature. This new light on nanotube hybrids shows their potential to push optoelectronics a step forward.

Published: September 2019

AbstractResearch on youth mentoring highlights the importance of the relationship quality between mentor and mentee; mentoring results in more positive outcomes when the mentee perceives the relationship as satisfying and trustworthy. Research on relationship quality shows that social skills are important for constructing new relationships. However, whereas improved social skills are often one of the main goals of youth mentoring, little is known about the importance of social skills for relationship quality in youth mentoring relations. In this study, we examined whether mentee's pre‐intervention social skills were related to mentor–mentee relationship quality as perceived by the mentee, and in turn, if relationship quality was associated with post‐intervention social skills. We additionally examined possible gender and age differences in these associations. Data were used from a two‐wave study that assessed relationship quality and social skills before and after one semester of mentoring of 390 secondary school students in a school‐based mentoring program. Results indicated that relationship quality was positively associated with post‐intervention social skills. However, only for young mentees pre‐intervention social skills were associated with better relationship quality. Moreover, only for young mentees, relationship quality mediated the association between pre‐ and post‐intervention social skills.

AbstractThe divinyldiarsene radical cations [{(NHC)C(Ph)}As]2(GaCl4) (NHC=IPr: C{(NDipp)CH}2 3; SIPr: C{(NDipp)CH2}2 4; Dipp=2,6‐iPr2C6H3) and dications [{(NHC)C(Ph)}As]2(GaCl4)2 (NHC=IPr 5; SIPr 6) are readily accessible as crystalline solids on sequential one‐electron oxidation of the corresponding divinyldiarsenes [{(NHC)C(Ph)}As]2 (NHC=IPr 1; SIPr 2) with GaCl3. Compounds 3–6 have been characterized by X‐ray diffraction, cyclic voltammetry, EPR/NMR spectroscopy, and UV/vis absorption spectroscopy as well as DFT calculations. The sequential removal of one electron from the HOMO, that is mainly the As−As π‐bond, of 1 and 2 leads to successive elongation of the As=As bond and contraction of the C−As bonds from 1/2→3/4→5/6. The UV/vis spectrum of 3 and 4 each exhibits a strong absorption in the visible region associated with SOMO‐related transitions. The EPR spectrum of 3 and 4 each shows a broadened septet owing to coupling of the unpaired electron with two 75As (I=3/2) nuclei.

Published: September 2019

AbstractDirect conversion of methane with carbon dioxide to value‐added chemicals is attractive but extremely challenging because of the thermodynamic stability and kinetic inertness of both molecules. Herein, the first dinuclear cluster species, RhVO3−, has been designed to mediate the co‐conversion of CH4and CO2to oxygenated products, CH3OH and CH2O, in the temperature range of 393–600 K. The resulting cluster ions RhVO3CO−after CH3OH formation can further desorb the [CO] unit to regenerate the RhVO3−cluster, leading to the successful establishment of a catalytic cycle for methanol production from CH4and CO2(CH4+CO2→CH3OH+CO). The exceptional activity of Rh‐V dinuclear oxide cluster (RhVO3−) identified herein provides a new mechanism for co‐conversion of two very stable molecules CH4and CO2.

AbstractCOF‐1 has a structure with rigid 2D layers composed of benzene and B3O3 rings and weak van der Waals bonding between the layers. The as‐synthesized COF‐1 structure contains pores occupied by solvent molecules. A high surface area empty‐pore structure is obtained after vacuum annealing. High‐pressure XRD and Raman experiments with mesitylene‐filled (COF‐1‐M) and empty‐pore COF‐1 demonstrate partial amorphization and collapse of the framework structure above 12–15 GPa. The ambient pressure structure of COF‐1‐M can be reversibly recovered after compression up to 10–15 GPa. Remarkable stability of highly porous COF‐1 structure at pressures at least up to 10 GPa is found even for the empty‐pore structure. The bulk modulus of the COF‐1 structure (11.2(5) GPa) and linear incompressibilities (k[100]=111(5) GPa, k[001]=15.0(5) GPa) were evaluated from the analysis of XRD data and cross‐checked against first‐principles calculations.
Asymmetric Alkenyl C−H Functionalization by CpxRhIII forms 2H‐Pyrrol‐2‐ones through [4+1]‐Annulation of Acryl Amides and Allenes
Authors: Wang Shou‐Guo , Liu Yang , Cramer Nicolai 
Published: September 2019

AbstractAn efficient CpxRhIII‐catalyzed enantioselective alkenyl C−H functionalization/[4+1] annulation of acryl amides and allenes is reported. The described transformation provides straightforward access to enantioenriched α,β‐unsaturated‐γ‐lactams bearing a quaternary stereocenter. The reaction operates under mild conditions, displays a broad functional‐group tolerance, and provides 2H‐pyrrol‐2‐ones with excellent selectivity of up to 97:3 er. Such scaffolds are frequently found in natural products and synthetic bioactive compounds and are of significant synthetic value. It is noteworthy that the allene serves as a one‐carbon unit in the [4+1]‐annulation.

Authors: Reckzeh Elena S. , Waldmann Herbert 
Published: September 2019

AbstractGlucose addiction is observed in cancer and other diseases that are associated with hyperproliferation. The development of compounds that restrict glucose supply and decrease glycolysis has great potential for the development of new therapeutic approaches. Addressing facilitative glucose transporters (GLUTs), which are often upregulated in glucose‐dependent cells, is therefore of particular interest. This article reviews a selection of potent, isoform‐selective GLUT inhibitors and their biological characterization. Potential therapeutic applications of GLUT inhibitors in oncology and other diseases that are linked to glucose addiction are discussed.

Published: September 2019

AbstractIsotopic labeling experiments performed with a newly identified bacterial trichoacorenol synthase established a 1,5‐hydride shift occurring in the cyclization mechanism. During EI‐MS analysis, major fragments of the sesquiterpenoid were shown to arise via cryptic hydrogen movements. Therefore, the interpretation of earlier results regarding the cyclization mechanism obtained by feeding experiments in Trichoderma is revised.

Published: September 2019

AbstractA universal, practical and scalable organocatalytic hydrocyanation manifold to provide β‐substituted acrylonitriles bearing an electron‐withdrawing functionality has been implemented. The catalytic manifold operates under the reactivity generation principle “a good nucleophile generates a strong base”, and it uses 1,4‐diazabicyclo[2.2.2]octane (DABCO) as the catalyst, activated terminal alkynes as substrates and acetone cyanohydrin as the cyanide source. The acrylonitriles obtained as E,Z mixtures are straightforwardly resolved by simple flash chromatography delivering the pure isomers in preparative amounts.
