With growing population, vertical spaces from skyscrapers are vast. Semi-transparent solar cells enable an effective pathway for vertical energy harvesting. With composition tunability, perovskite materials can be designed with different transparencies and colors. In this work, an ultra-high bandgap layered triple cation perovskite system was developed for the first time to meet the demand of clear optoelectronic applications; low dimensional triple cation perovskite thin films were fabricated using perovskite with the formula (PEA)2(CsxMA0.61-xFA0.39)39(Pb)40(Cl0.88-0.32xBr0.12+0.32x)121, 0 ≤ x ≤ 0.02 with DMSO as the appropriate solvent. The absorption edge of the material is around 410–430 nm, achieving great transparency to visible light. The structural, optical, and photovoltaic performances of the clear perovskite materials are explored with the variation of Cs contents via CsBr. The relation between thickness, transparency, and optoelectronic properties of the clear perovskite materials along with other physical properties were investigated. The highest photovoltaic conversion efficiency (PCE) of clear perovskite solar cells with 1.5% Cs was achieved to be 0.69% under xenon lamp irradiation at 100 mW/cm2 (1.5 mW/cm2 of UVA within 100 mW/cm2) and 5.24% under 365 nm UV irradiation at 2.4 mW/cm2. Photoresponsivity, external quantum efficiency (EQE), and detectivity were also determined for photodetector applications.

Angiosarcomas are a heterogeneous group of rare endothelial malignancies with a complex, not completely unravelled biology. They encompass primary (sporadically occurring) angiosarcomas of several origins and secondary angiosarcomas, which often arise due to DNA damaging factors including radiotherapy or ultraviolet light exposure. The optimal treatment of metastatic angiosarcomas is unclear and the prognosis is poor. In order to discover novel treatment strategies for angiosarcomas it is important to take the heterogeneity of these tumors into account. For this reason it is also important to have preclinical models available for the different clinical subtypes. Owing to the rarity of angiosarcomas, models are scarce. So far, only five human cell lines of angiosarcomas (all of the scalp after UV exposure) are available worldwide. In this paper we describe a novel established patient-derived xenograft model of a radiotherapy-induced angiosarcoma of the breast. The tumor was characterized by a MYC amplification, CD31 and ERG immunohistochemical positivity and was further characterized by using next generation sequencing (TruSight Oncology 500) in combination with the R-package XenofilteR to separate mouse from human sequence reads.

Endothelial shear stress (ESS) plays a key role in the clinical outcomes in native and stented segments; however, their implications in bypass grafts and especially in a synthetic biorestorative coronary artery bypass graft are yet unclear. This report aims to examine the interplay between ESS and the morphological alterations of a biorestorative coronary bypass graft in an animal model. Computational fluid dynamics (CFD) simulation derived from the fusion of angiography and optical coherence tomography (OCT) imaging was used to reconstruct data on the luminal anatomy of a bioresorbable coronary bypass graft with an endoluminal “flap” identified during OCT acquisition. The “flap” compromised the smooth lumen surface and considerably disturbed the local flow, leading to abnormally low ESS and high oscillatory shear stress (OSI) in the vicinity of the “flap”. In the presence of the catheter, the flow is more stable (median OSI 0.02384 versus 0.02635, p < 0.0001; maximum OSI 0.4612 versus 0.4837). Conversely, OSI increased as the catheter was withdrawn which can potentially cause back-and-forth motions of the “flap”, triggering tissue fatigue failure. CFD analysis in this report provided sophisticated physiological information that complements the anatomic assessment from imaging enabling a complete understanding of biorestorative graft pathophysiology.

Published: February 2023

Insect pest recognition has always been a significant branch of agriculture and ecology. The slight variance among different kinds of insects in appearance makes it hard for human experts to recognize. It is increasingly imperative to finely recognize specific insects by employing machine learning methods. In this study, we proposed a feature fusion network to synthesize feature presentations in different backbone models. Firstly, we employed one CNN-based backbone ResNet, and two attention-based backbones Vision Transformer and Swin Transformer to localize the important regions of insect images with Grad-CAM. During this process, we designed new architectures for these two Transformers to enable Grad-CAM to be applicable in such attention-based models. Then we further proposed an attention-selection mechanism to reconstruct the attention area by delicately integrating the important regions, enabling these partial but key expressions to complement each other. We only need part of the image scope that represents the most crucial decision-making information for insect recognition. We randomly selected 20 species of insects from the IP102 dataset and then adopted all 102 kinds of insects to test the classification performance. Experimental results show that the proposed approach outperforms other advanced CNN-based models. More importantly, our attention-selection mechanism demonstrates good robustness to augmented images.
Impact of time to full enteral feeding on long-term neurodevelopment without mediating by postnatal growth failure in very-low-birth-weight-infants
Authors: Yoon Shin Ae , Lee Myung Hee , Chang Yun Sil
Published: February 2023

This study aimed to determine if time to achieve full enteral feeding (TFF) directly impacted long-term neurodevelopmental delay (NDD) and whether long-term postnatal growth failure (PGF) was a mediator of this association in very-low-birth-weight (VLBW) infants. Using prospectively collected cohort data from the Korean Neonatal Network, we included eligible VLBW infants who achieved TFF at least once and classified enrolled infants into four groups using exposure severity (P1 to P4 as TFF < 16, 16–30, 31–45, and > 45 postnatal days, respectively). After adjusting for confounding variables, survival without NDD was significantly decreased in P4 infants compared with that in P2 infants. P1 infants had a lower risk of weight and height PGF than P2 infants; however, P4 infants had higher risks of height and head circumference PGF than P2 infants. Weight and height PGF were significantly associated with an increased risk of NDD. In mediation analysis, early and delayed TFF revealed direct positive and negative impacts, respectively, on the risk of NDD without mediation by PGF. TFF impacted survival without NDD, and PGF did not mediate this association in VLBW infants. Additionally, these results can be translated into evidence-based quality improvement practice.

Published: February 2023

The long-term use of chemical fertilizers to maintain agricultural production has had various harmful effects on farmland and has greatly impacted agriculture's sustainable expansion. Graphene, a unique and effective nanomaterial, is used in plant-soil applications to improve plant nutrient uptake, reduce chemical fertilizer pollution by relieving inadequate soil nutrient conditions and enhance soil absorption of nutrient components. We investigated the effects of graphene amendment on nutrient content, maize growth, and soil physicochemical parameters. In each treatment, 5 graphene concentration gradients (0, 25, 50, 100, and 150 g kg−1) were applied in 2 different types (single-layer and few-layers, SL and FL). Soil aggregates, soil accessible nutrients, soil enzyme activity, plant nutrients, plant height, stem diameter, dry weight, and fresh weight were all measured throughout the maize growth to the V3 stage. Compared to the control (0 g kg−1), we found that graphene increased the percentage of large agglomerates (0.25–10 mm) in the soil and significantly increased the geometric mean diameter (GMD) and mean weight diameter (MWD) values of > 0.25 mm water-stable agglomerates as the increase of concentration. Soil available nutrient content (AN, AP, and AK) increased, peaking at 150 g kg−1. Graphene boosted nutrient absorption by maize plants, and aboveground total nitrogen (TN), total phosphorus (TP), and total potassium (TK) contents rose with the increasing application, which raised aboveground fresh weight, dry weight, plant height, and stalk thickness. The findings above confirmed our prediction that adding graphene to the soil may improve maize plant biomass by enhancing soil fertility and improving the soil environment. Given the higher manufacturing cost of single-layer graphene and the greater effect of few-layer graphene on soil and maize plants at the same concentration, single-layer graphene and few-layer graphene at a concentration of 50 g kg−1 were the optimal application rates.
MSR1 is not required for obesity-associated inflammation and insulin resistance in mice

Published: February 2023

Obesity induces a chronic inflammatory state associated with changes in adipose tissue macrophages (ATMs). Macrophage scavenger receptor 1 (MSR1) has been implicated in the regulation of adipose tissue inflammation and diabetes pathogenesis; however, reports have been mixed on the contribution of MSR1 in obesity and glucose intolerance. We observed increased MSR1 expression in VAT of obese diabetic individuals compared to non-diabetic and single nuclear RNA sequencing identified macrophage-specific expression of MSR1 in human adipose tissue. We examined male Msr1−/− (Msr1KO) and WT controls and observed protection from obesity and AT inflammation in non-littermate Msr1KO mice. We then evaluated obese littermate Msr1+/− (Msr1HET) and Msr1KO mice. Both Msr1KO mice and Msr1HET mice became obese and insulin resistant when compared to their normal chow diet counterparts, but there was no Msr1-dependent difference in body weight, glucose metabolism, or insulin resistance. Flow cytometry revealed no significant differences between genotypes in ATM subtypes or proliferation in male and female mice. We observed increased frequency of proliferating ATMs in obese female compared to male mice. Overall, we conclude that while MSR1 is a biomarker of diabetes status in human adipose tissue, in mice Msr1 is not required for obesity-associated insulin resistance or ATM accumulation.

Published: February 2023

As rapidly developing area of intensive agriculture during the past half century, the oases in the source region of the Tarim River have encountered serious environmental challenges. Therefore, a comparative analysis of soil pollution characteristics and source-specific risks in different oases is an important measure to prevent and control soil pollution and provide guidance for extensive resource management in this area. In this study, the concentration of potential toxic elements (PTEs) was analyzed by collecting soil samples from the four oases in the source region of the Tarim River. The cumulative frequency curve method, pollution index method, positive matrix factorization (PMF) model, geographical detector method and health risk assessment model were used to analyze the pollution status and source-specific risk of potential toxic elements in different oases. The results showed that Cd was the most prominent PTE in the oasis agricultural soil in the source region of the Tarim River. Especially in Hotan Oasis, where 81.25% of the soil samples were moderately contaminated and 18.75% were highly contaminated with Cd. The PTEs in the Hotan Oasis corresponded to a moderate level of risk to the ecological environment, and the noncarcinogenic risk of soil PTEs in the four oases to local children exceeded the threshold (TH > 1), while the carcinogenic risk to local residents was acceptable (1E−06 < TCR < 1E−04). The research results suggested that the Hotan Oasis should be the key area for soil pollution control in the source region of the Tarim River, and agricultural activities and natural sources, industrial sources, and atmospheric dust fall are the priority sources that should be controlled in the Aksu Oasis, Kashgar Oasis and Yarkant River Oasis, respectively. The results of this study provide important decision-making support for the protection and management of regional agricultural soil and the environment.

Published: February 2023

Studying the impact of large-scale ecological projects, such as the Grain-for-Green Program (GGP), on ecosystem services (ES) is currently a frontier and hot topic of ecological research. The GGP can directly change land use and land cover, thus affecting ES. By comparing the changes of ecosystem service value (ESV) and ecosystem service scarcity value (ESSV) in Qinghai before and after the implementation of the GGP, this paper clarified the impact of the GGP on Qinghai from the angles of ecology and economics. This paper quantified and evaluated the land use dynamics, ESV, and ESSV in Qinghai from 1995 to 2020. The results showed that in the past 25 years, the total annual Normalized Difference Vegetation Index (NDVI) of Qinghai showed a trend of sustained growth. From 1995 to 2020, the ESV increased by 6.80%. After considering supply and demand, the ESSV showed a continuous upward trend, increasing by 719.38%. After implementation of the GGP, the increase of NDVI inhibited the increase of the ESSV. These findings from evaluation of the effect of the GGP implementation provide a theoretical basis for future policy implementation and, in particular, a reference for the evaluation of the ESV and the ESSV in Qinghai.

Published: February 2023

Although uncovered self-expandable metal stents (SEMSs) possess certain advantages such as averting cystic duct obstruction and stent migration, they are susceptible to ingrowth occlusion. The combination of the double bare stent (DBS) and endobiliary radiofrequency ablation (RFA) may reduce ingrowth. Hence, this study aimed to examine the utility of this method for the treatment of unresectable malignant distal biliary obstruction (MDBO). This prospective, single-center, pilot study enrolled 51 patients who met the eligibility criteria between February 2020 and January 2022. The study outcomes included technical success, clinical success, recurrent biliary obstruction (RBO), and other adverse events (AE) besides RBO associated with DBS placement with RFA for MDBO. The technical success rate was 98.0% (50/51). Clinical success was achieved in all patients in whom technical success was achieved. The rates of early and late AEs were 5.9% (3/51) and 8.0% (4/50), respectively. The incidence rate of RBO was 38.0% (19/50). Sludge occlusion, ingrowth occlusion, and overgrowth occlusion occurred in 26.0% (13/50), 8.0% (4/50), and 2.0% (1/50) of patients, respectively (the main cause of RBO was undeterminable in 1 patient). The median time to RBO was 241 days. DBS with RFA showed good technical feasibility, good long-term outcomes, acceptable AE rates, and most importantly, a low ingrowth occlusion rate when employed for the treatment of MDBO.
Reactivation-induced motor skill modulation does not operate at a rapid micro-timescale level
Authors: Herszage Jasmine , Bönstrup Marlene , Cohen Leonardo G. , Censor Nitzan
Published: February 2023

Abundant evidence shows that consolidated memories are susceptible to modifications following their reactivation. Processes of memory consolidation and reactivation-induced skill modulation have been commonly documented after hours or days. Motivated by studies showing rapid consolidation in early stages of motor skill acquisition, here we asked whether motor skill memories are susceptible to modifications following brief reactivations, even at initial stages of learning. In a set of experiments, we collected crowdsourced online motor sequence data to test whether post-encoding interference and performance enhancement occur following brief reactivations in early stages of learning. Results indicate that memories forming during early learning are not susceptible to interference nor to enhancement within a rapid reactivation-induced time window, relative to control conditions. This set of evidence suggests that reactivation-induced motor skill memory modulation might be dependent on consolidation at the macro-timescale level, requiring hours or days to occur.
Study on mechanism of effect of flowing water and transferring heat on rock mass temperature in curved fracture
Authors: Gao Junyi , Lu Changyu , Zhang Yonggang
Published: February 2023

Domestically and internationally, the effect of fracture flowing water and transferring heat on the temperature field of surrounding rock in high-level radioactive waste repositories is a popular research area. Compared with straight fracture flowing water and transferring heat, there are few relevant literatures about the heat transfer of curved fracture water flow. Based on the conceptive model of flowing water and transferring heat in curved fractured rock mass, the influence of flowing water and transferring heat in “I”, “L”, "Image missing", and "Image missing" shaped fractures on the temperature field of rock mass is calculated by using discrete element program. The findings indicate that: When the model goes into a stable state under four working conditions, the rock on the x = 0–2 m mostly forms a heat transfer path from left to right; the x = 2–4 m primarily forms a heat transfer path from bottom to top, and the temperature gradient reveals that the isotherm of 40–45 °C is highly similar to the shape of four different fractures, indicating that flowing water and transferring heat in the fracture configuration dominate the temperature field of the right side rock mass. The direction of the flowing water and transferring heat of the fracture exerts a dominant effect on the temperature of the rock mass than the length.
A monocarboxylate transporter-dependent mechanism confers resistance to exercise-induced fatigue in a high-altitude hypoxic environment
Authors: Gao Chen , Yang Binni , Li Yurong , Pei Wenjuan
Published: February 2023

The body is more prone to fatigue in a high-altitude hypoxic environment, in which fatigue occurs in both peripheral muscles and the central nervous system (CNS). The key factor determining the latter is the imbalance in brain energy metabolism. During strenuous exercise, lactate released from astrocytes is taken up by neurons via monocarboxylate transporters (MCTs) as a substrate for energy metabolism. The present study investigated the correlations among the adaptability to exercise-induced fatigue, brain lactate metabolism and neuronal hypoxia injury in a high-altitude hypoxic environment. Rats were subjected to exhaustive incremental load treadmill exercise under either normal pressure and normoxic conditions or simulated high-altitude, low-pressure and hypoxic conditions, with subsequent evaluation of the average exhaustive time as well as the expression of MCT2 and MCT4 in the cerebral motor cortex, the average neuronal density in the hippocampus, and the brain lactate content. The results illustrate that the average exhaustive time, neuronal density, MCT expression and brain lactate content were positively correlated with the altitude acclimatization time. These findings demonstrate that an MCT-dependent mechanism is involved in the adaptability of the body to central fatigue and provide a potential basis for medical intervention for exercise-induced fatigue in a high-altitude hypoxic environment.
Pixel-by-pixel autofluorescence corrected FRET in fluorescence microscopy improves accuracy for samples with spatially varied autofluorescence to signal ratio
Authors: Rebenku István , Lloyd Cameron B. , Szöllősi János , Vereb György
Published: February 2023

The actual interaction between signaling species in cellular processes is often more important than their expression levels. Förster resonance energy transfer (FRET) is a popular tool for studying molecular interactions, since it is highly sensitive to proximity in the range of 2–10 nm. Spectral spillover-corrected quantitative (3-cube) FRET is a cost effective and versatile approach, which can be applied in flow cytometry and various modalities of fluorescence microscopy, but may be hampered by varying levels of autofluorescence. Here, we have implemented pixel-by-pixel autofluorescence correction in microscopy FRET measurements, exploiting cell-free calibration standards void of autofluorescence that allow the correct determination of all spectral spillover factors. We also present an ImageJ/Fiji plugin for interactive analysis of single images as well as automatic creation of quantitative FRET efficiency maps from large image sets. For validation, we used bead and cell based FRET models covering a range of signal to autofluorescence ratios and FRET efficiencies and compared the approach with conventional average autofluorescence/background correction. Pixel-by-pixel autofluorescence correction proved to be superior in the accuracy of results, particularly for samples with spatially varying autofluorescence and low fluorescence to autofluorescence ratios, the latter often being the case for physiological expression levels.

During COVID-19 pandemic, quality of living was impacted by social isolation, loneliness, and altered sleep habits. The aims of this study were (1) to examine the relationship between physical activity (PA) levels with insomnia and loneliness among adults during Spain’s first COVID-19 wave of lockdown and its impact on women and (2) to examine the digital technologic resources used to support both PA and other recreational activities in women. A cross-sectional design was used. An anonymous 15-min online survey was conducted in Spain to adults (≥ 18 years old) during the first COVID-19 lockdown, a 40-day period. A snowball distribution method was employed using personal email and social networks (Facebook, Whatsapp, Linkedin, Twitter). Variables studied included: socio-demographic items, insomnia, loneliness, PA, and digital technologic resources. A total of 996 adults (females = 663, 66.6%) completed the survey. Higher education levels were associated with greater PA levels (p-value < 0.001). Women presented with higher insomnia risk than men with low PA levels (OR = 1.9, CI = 1.25; 2.95). Living with family members or other individuals was related to lower insomnia risk. A strong correlation between medium–high PA levels was found with greater digital technology resources (DTS) than individuals with low PA levels. Females used significantly more DTS than males (p-value < 0.001). No significant associations between DTS were found with age or academic education level. PA levels, sex, and loneliness were related to insomnia risk. A strong correlation between PA and DTS use was observed. Participants with medium–high PA levels and females use them more than those with low PA levels and males. We recommend promoting the PA through digital technologies for women. This recommendation would also improve sleep disorders in women who present higher insomnia risks than men.
An open automation system for predatory journal detection

Published: February 2023

The growing number of online open-access journals promotes academic exchanges, but the prevalence of predatory journals is undermining the scholarly reporting process. Data collection, feature extraction, and model prediction are common steps in tools designed to distinguish between legitimate and predatory academic journals and publisher websites. The authors include them in their proposed academic journal predatory checking (AJPC) system based on machine learning methods. The AJPC data collection process extracts 833 blacklists and 1213 whitelists information from websites to be used for identifying words and phrases that might indicate the presence of predatory journals. Feature extraction is used to identify words and terms that help detect predatory websites, and the system’s prediction stage uses eight classification algorithms to distinguish between potentially predatory and legitimate journals. We found that enhancing the classification efficiency of the bag of words model and TF-IDF algorithm with diff scores (a measure of differences in specific word frequencies between journals) can assist in identifying predatory journal feature words. Results from performance tests suggest that our system works as well as or better than those currently being used to identify suspect publishers and publications. The open system only provides reference results rather than absolute opinions and accepts user inquiries and feedback to update the system and optimize performance.
Combating errors in quantum communication: an integrated approach
Authors: Bala Rajni , Asthana Sooryansh , Ravishankar V.
Published: February 2023

Near-term quantum communication protocols suffer inevitably from channel noises, whose alleviation has been mostly attempted with resources such as multiparty entanglement or sophisticated experimental techniques. Generation of multiparty higher dimensional entanglement is not easy. This calls for exploring realistic solutions which are implementable with current devices. Motivated particularly by the difficulty in generation of multiparty entangled states, in this paper, we have investigated error-free information transfer with minimal requirements. For this, we have proposed a new information encoding scheme for communication purposes. The encoding scheme is based on the fact that most noisy channels leave some quantities invariant. Armed with this fact, we encode information in these invariants. These invariants are functions of expectation values of operators. This information passes through the noisy channel unchanged. Pertinently, this approach is not in conflict with other existing error correction schemes. In fact, we have shown how standard quantum error-correcting codes emerge if suitable restrictions are imposed on the choices of logical basis states. As applications, for illustration, we propose a quantum key distribution protocol and an error-immune information transfer protocol.
Estimating COVID-19 vaccine uptake and its drivers among migrants, homeless and precariously housed people in France

Published: February 2023

Background

Migrants, people experiencing homelessness (PEH), or precariously housed (PH) are at high risk for COVID-19 infection, hospitalization, and death from COVID-19. However, while data on COVID-19 vaccine uptake in these populations are available in the USA, Canada, and Denmark, we are lacking, to the best of our knowledge, data from France.

Methods

In late 2021, we carried out a cross-sectional survey to determine COVID-19 vaccine coverage in PEH/PH residing in Ile-de-France and Marseille, France, and to explore its drivers. Participants aged over 18 years were interviewed face-to-face where they slept the previous night, in their preferred language, and then stratified for analysis into three housing groups (Streets, Accommodated, and Precariously Housed). Standardized vaccination rates were computed and compared to the French population. Multilevel univariate and multivariable logistic regression models were built.

Results

We find that 76.2% (95% confidence interval [CI] 74.3–78.1) of the 3690 participants received at least one COVID-19 vaccine dose while 91.1% of the French population did so. Vaccine uptake varies by stratum, with the highest uptake (85.6%; reference) in PH, followed by Accommodated (75.4%; adjusted odds-ratio = 0.79; 95% CI 0.51–1.09 vs. PH) and lowest in Streets (42.0%; AOR = 0.38; 95%CI 0.25–0.57 vs. PH). Use for vaccine certificate, age, socioeconomic factors, and vaccine hesitancy is associated with vaccination coverage.

Conclusions

In France, PEH/PH, and especially the most excluded, are less likely than the general population to receive COVID-19 vaccines. While vaccine mandate has proved an effective strategy, targeted outreach, on-site vaccinations, and sensitization activities are strategies enhancing vaccine uptake that can easily be replicated in future campaigns and other settings.

New predictions for radiation-driven, steady-state mass-loss and wind-momentum from hot, massive stars
Authors: Björklund R. , Sundqvist J. O. , Singh S. M. , Puls J. , Najarro F.
Published: February 2023

Context. Massive stars lose a large fraction of their mass to radiation-driven winds throughout their entire life. These outflows impact both the life and death of these stars and their surroundings.

Aims. Theoretical mass-loss rates of hot, massive stars are derived to be used in applications such as stellar evolution. The behaviour of these rates in the OB-star regime is analysed, and their effects on massive-star evolution predictions studied.

Methods. Dynamically consistent models are computed by solving the spherically symmetric, steady-state equation-of-motion for a large grid of hot, massive stars with different metallicities. The radiative acceleration is derived from non-local thermodynamic equilibrium radiative transfer in the co-moving frame, and all models cover a large spatial range from deep subsonic atmospheric layers into the radiation-driven and highly supersonic wind outflow. The resulting mass-loss rates are used to derive a simple scaling recipe with stellar parameters (luminosity, mass, effective temperature, and metallicity), and the new recipe is used to evaluate some first impacts upon massive-star evolution tracks.

Results. We provide a new prescription for steady-state, radiation-driven mass-loss from hot, massive stars depending on their fundamental parameters. In accordance with our previous work, the rates for O stars are lower a factor of ~3 than the rates typically used in previous stellar-evolution calculations, where differences generally decrease with increasing luminosity and temperature. For cooler B giants/supergiants we find larger discrepancies, of up to one or even two orders of magnitude. This arises because we do not find any systematic increase in mass-loss rates below the so-called bi-stability region; indeed, our results do not show any sign of a significant bi-stability jump within the parameter range covered by the grid (Teff ≥ 15 kK). Due to the lower mass-loss rates we find that massive-star envelopes are not easily stripped by means of standard steady-state winds, making it difficult to create classical Wolf-Rayet stars via this channel. Moreover, since the stars retain more mass right before they die as supernovae, our new rates make it possible to create black holes of higher masses than in previous models, even at Galactic metallicity. However, a remaining key uncertainty regarding these predictions concerns unsteady mass-loss for very high-luminosity stars close to the Eddington limit as well as the impact of non-line-driven winds.
Paysages : entre anthropologie et clinique

La relation au paysage, ou plus largement à l’environnement, est marquée d’ambivalences. Elle met en question nos notions centrées sur un individu séparé du reste du monde, enclos en lui- même, au sein d’un univers bien délimité avec des frontières ontologiques incontestables. Pour maintes sociétés humaines l’environnement est une enveloppe vivante dotée d’éléments différents mais sans rupture ontologique entre les uns et les autres. H. Searles a poussé le plus loin l’étude de ce qu’il nomme « l’environnement non humain ». L’espace potentiel que délivrent les significations et les valeurs communes induit un sentiment de familiarité, de reconnaissance mutuelle entre le sujet le monde. Certes, à tout moment l’accord peut être rompu par un mauvais coucheur, un malentendu, un faux mouvement, un fantasme, mais globalement, pour reprendre Winnicott, le monde quand il est enveloppé de sens et de valeurs fonctionne comme une « mère suffisamment bonne ».
Le sertâo comme paysage-miroir de la mélancolie
Authors: Martins Karla Patricia Holanda , Lima Maria Celina Peixoto , Pinheiro Teresa
Published: February 2023

Le présent article délimitera les interfaces entre la psychanalyse, l’histoire et la littérature, provoquées par l’idée que le paysage du sertâo brésilien, décrit par les récits historiques et littéraires du Brésil au milieu de la deuxième décennie du XIXe siècle et du début du XXe siècle, formalise une sorte de visage-paysage analogue à celui que nous trouvons dans les descriptions faites par les sujets mélancoliques de leurs environnements affectifs présents dans leurs relations inaugurales de vie. Il vise également, à travers une recherche théorique et bibliographique, à démontrer l’actualité des propositions freudiennes de 1915/1917, présentées notamment dans le texte « Deuil et Mélancolie », comme aussi ses conséquences pour une théorie de la culture. Nous comprenons que la mélancolie peut être comprise comme une figure qui met en jeu les luttes pour délimiter des espaces imaginaires de frontières Moi-Autre dans une tentative belliqueuse de dénoncer les impostures identitaires, dans la croyance en une vérité à assurer dans le langage. Nous signalerons, à la fin de l’article, les conséquences pour le travail analytique de la position stratégique prise dans la mélancolie, à partir du visage-sertâo. Avec la fonction de délimiter les frontières du Moi-Autre, le travail analytique semble suivre, sous la forme de ce qui avait été indiqué par Freud en 1913, comme une description de paysages, avec une sincérité aiguë, configurant une sorte de texte imagé, caractérisé par la formalisation minutieusement descriptive d’un scénario, à la recherche du mot exact qui annulerait sa valeur polysémique.
Le paysage c’est la maison des autres

Le paysage n’est pas seulement une étendue qui s’offre à la vue d’un spectateur, il est la résultante de multiples présences, de traversées et de perçus. La pensée chinoise ancienne nous parle de détour, de convergences et d’une certaine « culture du cœur ».
Réalité virtuelle et réalité psychique : Black Mirror et la vie éternelle à San Junipero
Authors: Rabeyron Thomas , Charlet Olivier
Published: February 2023

Nous proposons dans ce travail d’analyser un épisode de la série Black Mirror intitulé San Junipero dans le but de mieux comprendre les différentes formes de transformations subjectives induites par les nouvelles technologies. Ainsi, après avoir décrit dans les grandes lignes l’histoire d’amour au cœur de cet épisode, nous décrivons les processus psychiques associés à la réalité virtuelle, en particulier le narcissisme primaire et le rêve. Les relations complexes entre jouissance, trauma et désir sont ensuite abordées à travers le prisme des propriétés symboligènes de l’espace virtuel. Cela nous conduit à décrire plusieurs fantasmes originaires associés à la réalité virtuelle et les processus sous-jacent au désir d’éternité exprimés par son intermédiaire. Nous proposons en conclusion quelques réflexions relatives à la manière dont ces évolutions techniques se situent à la rencontre entre le réel et l’hyper-réel et la manière dont les cliniciens peuvent être amenés à les considérer.
Minimizing total tardiness in a two-machine flowshop with uncertain and bounded processing times
Authors: Allahverdi Muberra
Published: February 2023

The two-machine flowshop scheduling problem with the performance measure of total tardiness is addressed. This performance measure is essential since meeting deadlines is a crucial part of scheduling and a major concern for some manufacturing systems. The processing times on both machines are uncertain variables and within some lower and upper bounds. This is due to uncertainty being an integral part of some manufacturing settings, making it impossible to predict processing times in advance. To the best of the author’s knowledge, this problem is addressed for the first time in this paper. A dominance relation is established and nineteen algorithms are proposed. These algorithms are extensively evaluated through randomly generated data for different numbers of jobs and four different distributions, representing both symmetric and non-symmetric distributions. Computational experiments show that the presented algorithms perform extremely well when compared with a random solution. In particular, the best of the considered 19 algorithms reduces the error of the random solution by 99.99% and the error of the worst algorithm (among the 19 algorithms) by 99.96%. The results are confirmed by a test of hypothesis and this algorithm is recommended.

Die Verwendung von pflanzlichen Heilmitteln und Nahrungsergänzungsmitteln
ist weit verbreitet. In vielen Ländern der Welt weisen die
Verkaufszahlen auf eine steigende Beliebtheit dieser Produkte hin. Daher ist die
Gewährleistung der Sicherheit von pflanzlichen Produkten eine
Priorität der öffentlichen Gesundheit. Dieser Artikel beschreibt
die Aufgaben und Ziele des Botanical Safety Consortiums (BSC) – einer
öffentlich-privaten Partnerschaft. Diese Partnerschaft ist das Ergebnis
einer Absichtserklärung zwischen der Gesundheitsbehörde der USA
(FDA), dem National Institute of Environmental Health Sciences (NIEHS, eine
Unterabteilung des Ministeriums für Gesundheitspflege und Soziale
Dienste der Vereinigten Staaten) und einer gemeinnützigen Organisation,
dem Health and Environmental Sciences Institute (HESI). Das BSC dient als
globales Forum für Wissenschaftler aus Regierungen, Hochschulen,
Gesundheitsfürsorgegruppen, Industrie und gemeinnützigen
Organisationen, um gemeinsam an der Anpassung und Integration neuer
Ansatzmethoden (NAM) für routinemäßige
Sicherheitsbewertungen von Pflanzenstoffen zu arbeiten.

Die Ziele des BSC sind: 1) eine weltweite Zusammenarbeit, um existierende
Sicherheitstests besser zu nutzen; 2) geeignete Methoden der chemischen
Charakterisierung von Pflanzenstoffen festzusetzen; 3) pragmatische,
zweckmäßige NAM zu identifizieren, um die Sicherheit von
pflanzlichen Inhaltsstoffen und Fertigpräparaten zu bewerten; 4) eine
Bewertung dieser Methoden mittels Vergleich mit derzeit verfügbaren
Informationen zur Sicherheit von ausgewählten Pflanzenstoffen; 5) und
die Integration dieser NAM in ein System, das die Bewertung von Pflanzenstoffen
erleichtern kann. Der Schwerpunkt des BSC liegt zunächst auf
Phytopharmaka und Nahrungsergänzungsmitteln, welche oral verabreicht
werden, jedoch kann dieser Ansatz in zukünftigen Arbeitsphasen erweitert
werden. Dieser Artikel beinhaltet einen Überblick über die
Struktur, Ziele und Strategien dieser Initiative und erläutert die
ersten Ziele, nämlich die Auswahl der Test-Pflanzenstoffe, basierend auf
publizierten toxikologischen Daten.
