AbstractFlue-cured tobacco grading plays a crucial role in tobacco leaf purchase and the formulation of tobacco leaf groups. However, the traditional flue-cured tobacco grading mode is usually manual, which is time-consuming, laborious, and subjective. Hence, it is essential to research more efficient and intelligent flue-cured tobacco grading methods. Most existing methods suffer from the more classes less accuracy problem. Meanwhile, limited by different industry applications, the flue-cured tobacco datasets are hard to be obtained publicly. The existing methods employ relatively small and lower resolution tobacco data that are hard to apply in practice. Therefore, aiming at the insufficiency of feature extraction ability and the inadaptability to multiple flue-cured tobacco grades, we collected the largest and highest resolution dataset and proposed an efficient flue-cured tobacco grading method based on deep densely convolutional network (DenseNet). Diverging from other approaches, our method has a unique connectivity pattern of convolutional neural network that concatenates preceding tobacco feature data. This mode connects all previous layers to the subsequent layer directly for tobacco feature transmission. This idea can better extract depth tobacco image information features and transmit each layer’s data, thereby reducing the information loss and encouraging tobacco feature reuse. Then, we designed the whole data pre-processing process and experimented with traditional and deep learning algorithms to verify our dataset usability. The experimental results showed that DenseNet could be easily adapted by changing the output of the fully connected layers. With an accuracy of 0.997, significantly higher than the other intelligent tobacco grading methods, DenseNet came to the best model for solving our flue-cured tobacco grading problem.

AbstractEven though Helicobacter pylori (H. pylori) is a serious pathogen, its origin is unknown. Poultry (Chicken, Turkey, Quebec, Goose, and Ostrich) are consumed as a regular protein source by a large number of people across the world; therefore, sanitary ways of delivering poultry for food are important for global health. As a result, we looked at the distribution of the pathogenicity cagA, vacA, babA2, oipA, and iceA in H. pylori isolates in poultry meat, as well as their antimicrobial resistance. Wilkins Chalgren anaerobic bacterial medium was used to cultivate 320 raw poultry specimens. Disk diffusion and Multiplex-PCR were used to investigate antimicrobial resistance and genotyping patterns, separately. H. pylori was found in 20 of 320 (6.25%) raw poultry samples. The highest incidence of H. pylori was found in chicken raw meat (15%), whereas the fewest was found in Goose and Quebec (0.00%). Resistance to ampicillin (85%), tetracycline (85%), and amoxicillin (75%) were greatest in H. pylori isolates. The percentage of H. pylori isolates with a MAR value of more than 0.2 was 17/20 (85%). The most prevalent genotypes discovered were VacA s1a (75%), m1a (75%), s2 (70%) and m2 (65%), and cagA (60%). The most typically discovered genotype patterns were s1am1a (45%), s2m1a (45%), and s2m2 (30%). BabA2, OipA + , and OipA− genotypes were found in 40%, 30%, and 30% of the population. In summary, the poultry flesh was polluted by H. pylori, with the babA2, vacA, and cagA genotypes being more prevalent. The simultaneous occurrence of vacA, cagA, iceA, oipA, and babA2 genotypes in antibiotic-resistant H. pylori bacteria implies a serious public health concern about raw poultry eating. In the future, researchers should look into H. pylori's resistance to multiple antibacterial drugs in Iran.
The thermodynamic and life-cycle assessments of a novel charging station for electric vehicles in dynamic and steady-state conditions

Published: July 2023

AbstractThe current study performs the thermodynamic and life-cycle assessments (LCA) of a novel charging station in two system designs. The goal is to design an efficient charging station for electric vehicles with high efficiencies and low environmental impacts using Solid Oxide Fuel Cell (SOFC) technology. SOFC is considered a sustainable and environmentally friendly technology to generate electricity compared to combustion engines. To ameliorate the performance, the exhaust heat of the SOFC stacks will be recovered for hydrogen production in an electrolyzer. The system uses four SOFCs to charge the electric vehicles while the output heat is recovered by an Organic Rankine Cycle (ORC) to generate further electricity for hydrogen production in an electrolyzer. In the first design, it is assumed that the SOFC stacks will work full-load during the 24 h of the day, while the second design considers full-load operation for 16 h and part-load (30%) operation for 8 h. The second design of the system analyzes the possibility of integrating a $${\mathrm{LiMn}}_{2}{\mathrm{O}}_{4}$$

lithium-ion battery stores the excessed electricity once the power load is low and acts as a backup in high power demands. Results of the thermodynamic analysis calculated the overall efficiencies of 60.84% and 60.67% for the energy and exergy, respectively, with the corresponding power and hydrogen production of 284.27 kWh and 0.17 g/s. It was observed that higher current density would increase the output of SOFC while reducing the overall energy and exergy efficiencies. In dynamic operation, the use of the batteries can well balance the change of the power loads and improve the dynamic response of the system to the simultaneous changes in the power demand. LCA results also showed that the 284.27kWh system leads to global warming (kg $${\mathrm{CO}}_{2}$$

In this regard, the usage of PEME has the lowest impact on the environment in comparison to SOEC, and ALE. A comparison between the environmental impacts of different ORC’s working fluids also suggested against the usage of R227ea while R152a showed promising results to be used in the system. The size and weight study also revealed that the battery benefits from the lowest volume and weight in comparison to the other components. Among the considered components in this study, the SOFC unit and the PEME have by far the highest volume.
An appraisal of the principal concerns and controlling factors for Arsenic contamination in Chile

Published: July 2023

AbstractAlthough geogenic Arsenic (As) contamination is well-recognized in northern Chile, it is not restricted to this part of the country, as the geological conditions favoring As release to the human environment exist across the country as well, although not at the same level, based on comparatively fewer studies in central and southern Chile. The present work provides a critical evaluation of As sources, pathways, and controls with reports and case studies from across the country based on an exhaustive bibliographic review of its reported geogenic sources and processes that affect its occurrence, systematization, and critical revision of this information. Arc magmatism and associated geothermal activities, identified as the primary As sources, are present across the Chilean Andes, except for the Pampean Flat Slab and Patagonian Volcanic Gap. Metal sulfide ore zones, extending from the country’s far north to the south-central part, are the second most important geogenic As source. While natural leaching of As-rich mineral deposits contaminates the water in contact, associated mining, and metallurgical activities result in additional As release into the human environment through mining waste and tailings. Moreover, crustal thickness has been suggested as a principal controlling factor for As release, whose southward decrease has been correlated with lower As values.
Surface charge accumulation of post insulator: Dominant charge transition under different conditions
Authors: Liang Fangwei , Wang Feng , Chen She , Sun Qiuqin , Zhong Lipeng 
Published: July 2023

AbstractAn insulator surface charge may be responsible for flashover along the insulator surface. In this study, experimental investigations of post insulator surface charge are performed using a variety of voltage, gas type, and gas pressure conditions. Combining the model of surface charge transport, the dominant charge transition is revealed considering gas partial discharge. The results show that hetero‐polar charge accumulates near the high voltage electrodes on the insulator at one atmospheric pressure with an applied DC voltage ranging from −10 to −60 kV. The area ratio of the hetero‐polar charge increases from 23% to 53%. It also generates a reversed polarity of surface charges. Under −20 kV, the surface charge near the grounded electrode gradually becomes homo‐polar charges with the decrease of SF6 in 0.5 MPa SF6/N2 gas mixtures. In this case, the most dominant pathway for charge accumulation is through the insulation gas rather than the insulator. For the 20%SF6/80%N2 gas mixtures, homo‐polar charge speckles appear near the grounded plate electrode when the pressure of SF6/N2 gas mixtures decreases to 0.1 MPa. This means that the partial discharge occurs in gas side under a lower gas pressure. Refer to the presenting findings, the dominant charge transition on post insulators is provided as an important reference.
Two‐stream spatiotemporal networks for skeleton action recognition
Authors: Wang Lei , Zhang Jianwei , Yang Shanmin , Gu Song 
Published: July 2023

AbstractSkeleton‐based neural networks have been considered a focus for human action recognition (HAR). It is noteworthy that the existing skeleton‐based methods are not capable of combining the spatial and temporal features reasonably to derive more effective high‐level representations, and it continues to be a challenging task of learning and representing the skeleton action discriminatively. In this study, a novel two‐stream spatiotemporal network (TSTN) is proposed, which is capable of processing the spatial and temporal features respectively and collectively to achieve a better representation and understanding of human action. The temporal branch stacks three gate recurrent unit (GRU) blocks in a new architecture to encode the temporal correlations from different aspects of human action, achieving high‐level temporal semantic feature expressions. The spatial branch encodes the spatial features with multi‐stacked graph convolutional network (GCN) blocks. Self‐attention mechanisms incorporated with the graph structure of the skeleton are explored to add weight influence and structural hints to further enhance the performance. The experimental results verify the effectiveness and superiority of the proposed model in skeleton action recognition; the model reaches state‐of‐the‐art on specific datasets.

Published: July 2023

AbstractWe have witnessed the flourish of bioelectronics, brain–computer interface, and brain science programme in recent decades. In this review, the up‐to‐date advances of dielectric, piezoelectric, and ferroelectric nanomaterials in the biomedical applications are summarised. Biomolecular detection methods have been developed, including dielectric‐gated field‐effect transistor, dielectrophoresis, non‐linear dielectric response, and optical tweezer. Endogenous bioelectricity is a crucial in cell proliferation, migration, differentiation, intracellular communication, neuronal activity, tissue growth. Piezoelectric and ferroelectric materials can be utilised as energy transducer to monitor physiological signal, such as blood pressure or respiration, and directly stimulate cell differentiation, neuronal regeneration, tissue repairment etc. They can also catalyse the electrochemical reaction of organisms through piezoelectricity. The intrinsic relevance between neuronal and ferroelectric polarisation signals inspires the application of the ferroelectrics in the modern intelligent bioelectronics like the artificial retina.
Numerical investigation on wake characteristics of floating offshore wind turbine under pitch motion
Authors: Tang Rundong , Cao Renjing 
Published: July 2023

AbstractThe floating offshore wind turbine platform is subject to six degrees‐of‐freedom motions due to the influence of wind, waves, and currents. To examine the impact of pitch motion on the wake characteristics of offshore wind turbines, this research focused on investigating the wind turbine wake under pitch motion using the RANS
model and the overset grid technique based on OpenFOAM. The simulation accounted for wind shear flow conditions and simplified the movements of the six degrees‐of‐freedom of floating platform. Results showed that the wind turbine wake recovery rate increased with pitch motion, and that the recovery rate increased with the frequency and amplitude of the pitch motion. The wind velocity recovery rate of near‐wake was sensitive to small amplitudes, while the far‐field wake was unaffected. When the amplitude was larger, pitch motion accelerated the wind velocity recovery rate in all wake areas, leading to more pronounced diffusion. These findings provide insight into the mechanism of wake generation and diffusion under pitch motion in floating offshore wind turbines and offer a basis for enhancing the wake deficit model of floating offshore wind farms.

Context. Optical secondary eclipse measurements of small planets can provide a wealth of information about the reflective properties of these worlds, but the measurements are particularly challenging to attain because of their relatively shallow depth. If such signals can be detected and modeled, however, they can provide planetary albedos, thermal characteristics, and information on absorbers in the upper atmosphere.
Aims. We aim to detect and characterize the optical secondary eclipse of the planet LTT 9779 b using the CHaracterising ExOPlanet Satellite (CHEOPS) to measure the planetary albedo and search for the signature of atmospheric condensates.
Methods. We observed ten secondary eclipses of the planet with CHEOPS. We carefully analyzed and detrended the light curves using three independent methods to perform the final astrophysical detrending and eclipse model fitting of the individual and combined light curves.
Results. Each of our analysis methods yielded statistically similar results, providing a robust detection of the eclipse of LTT 9779 b with a depth of 115±24 ppm. This surprisingly large depth provides a geometric albedo for the planet of 0.80−0.17+0.10, consistent with estimates of radiative-convective models. This value is similar to that of Venus in our own Solar System. When combining the eclipse from CHEOPS with the measurements from TESS and Spitzer, our global climate models indicate that LTT 9779 b likely has a super metal-rich atmosphere, with a lower limit of 400× solar being found, and the presence of silicate clouds. The observations also reveal hints of optical eclipse depth variability, but these have yet to be confirmed.
Conclusions. The results found here in the optical when combined with those in the near-infrared provide the first steps toward understanding the atmospheric structure and physical processes of ultrahot Neptune worlds that inhabit the Neptune desert.
Fooled by Significance Testing: An Analysis of the LOVIT Vitamin C Trial
Authors: Sidebotham David 
Published: July 2023

In this article, I discuss the potential pitfalls of interpreting p values, confidence intervals, and declarations of statistical significance. To illustrate the issues, I discuss the LOVIT trial, which compared high-dose vitamin C with placebo in mechanically ventilated patients with sepsis. The primary outcome – the proportion of patients who died or had persisting organ dysfunction at day 28 – was significantly higher in patients who received vitamin C (p = .01). The authors had hypothesized that vitamin C would have a beneficial effect, although the prior evidence for benefit was weak. There was no prior evidence for a harmful effect of high-dose vitamin C. Consequently, the pretest probability for harm was low. The sample size was calculated assuming a 10% absolute risk difference, which was optimistic. Overestimating the effect size when calculating the sample size leads to low power. For these reasons, we should be skeptical that vitamin C causes harm in septic patients, despite the significant result.
p-values and confidence intervals are probabilities concerning the chance of obtaining the observed data. However, we are more interested in the chance the intervention has a real effect on the outcome. That is to say, we are more interested in whether the hypothesis is true. A Bayesian approach allows us to estimate the false positive risk, which is the post-test probability there is no effect of the intervention. The false positive risk for the LOVIT trial (calculated from the published summary data using uniform priors for the parameter values) is 70%.
Most likely, high-dose vitamin C does not cause harm in septic patients. Most likely it has no effect at all. If there is an effect, it is probably small and most likely beneficial.
Von der Liebe
Authors: Jordan Wolfgang 
Published: July 2023

ZusammenfassungIn einem Gedicht und einer Fabel sind die wesentlichen philosophischen Theorien zur Liebe gefasst. Obwohl es viele Anknüpfungen zwischen der Liebe, dem psychischen Erleben und psychiatrischen Störungsbildern gibt, scheint die Liebe der Psychiatrie suspekt zu sein. Möglicherweise handelt es sich um einen Grundkomplex der Psychiatrie, sich nicht nur der Liebe zu entziehen, sondern darüber ebenfalls die grundlegenden Themen der Sexualität und Elternschaft psychisch Kranker auszuklammern.

Authors: Cechnicki Andrzej , Bielańska Anna 
Published: July 2023

ZusammenfassungDer Einsatz der Dramatherapie in der Behandlung von Menschen mit einer Schizophrenie in einer Theatergruppe, hat in Krakau eine Tradition von nahezu 40 Jahren. Die Vorbereitung der Aufführungen und Auftritte vor Publikum nutzen die aus dem Training sozialer Kompetenzen bekannten Inhalte. Es wird eine kurze Beschreibung der Entwicklung des „Psyche“-Theaters und seines Stellenwerts in einem gemeindebasierten umfassenden Behandlungsprogramm am Beispiel von Shakespeares „Ein Sommernachtstraum“ gegeben. Die Kasuistik einer Patientin, dient als Illustration, um die Bedeutung der Rolle im Theaterstück für die anschließende eingehende individuelle Psychotherapie zu reflektieren. Die Autoren unterstreichen die Attraktivität öffentlicher Vorstellungen in einem Krakauer Theater, die es ermöglichen, sie für Begegnungen mit jungen Menschen zu nutzen. Sie haben einen enormen pädagogischen Wert für den Abbau von Vorurteilen gegenüber psychisch kranken Menschen.
Liebe und Freundschaftsliebe als Voraussetzung für ein glückliches Leben und eine gelingende Gemeinschaft – Positionen aus der Philosophie der Antike
Authors: Vogt Sabine 
Published: July 2023

ZusammenfassungDie vielfältigen Erscheinungsformen der Liebe lassen sich in verschiedenen Konzepten der antiken Philosophie nachzeichnen. Dabei treten zwei grundsätzliche und gegensätzliche Kategorien zutage: Asymmetrie und Symmetrie in der Beziehung zwischen zwei Menschen. Während asymmetrische Liebes-Formen das Potenzial der Nichterfüllung und daraus folgenden individuellen Verzweiflung in sich tragen, bieten symmetrische Formen der Liebe und Freundschaft bzw. ,Freundschaftsliebe‘, wie sie seit Aristoteles formuliert werden, die Chance einer gleichwertigen und gleichberechtigten Beziehung des gegenseitigen Austausches ,auf Augenhöhe‘ und bilden somit nicht nur eine Voraussetzung für ein glückliches Leben von Einzelnen, sondern auch die Basis für eine gelingende und gerechte soziale Gemeinschaft.
Isolated Superior Mesenteric Artery Dissection following Blunt Trauma: A Case Report
Authors: Shirakabe Katsudai , Kanzaki Masaki 
Published: July 2023

AbstractIsolated superior mesenteric artery dissection (ISMAD) is rare, with symptoms ranging from asymptomatic to acute intestinal ischemia. Risk factors for ISMAD include hypertension, atherosclerosis, abnormal elastic fibers, and pregnancy. In the present case, blunt trauma, which has not been previously reported, was suggested as a risk factor. A 46-year-old man was brought to the emergency room after he was found unconscious after a motor vehicle collision. At presentation, he had no abdominal symptoms; however, on the fourth day of admission, he presented with severe abdominal pain and vomiting. A contrast-enhanced computed tomography scan revealed an ISMAD with associated intestinal ischemia and necrosis; hence, emergency surgery was performed. Herein, we report a case of ISMAD caused by blunt abdominal trauma.
How do professionals assess security risks in practice? An exploratory study
Authors: Harris William , Sadok Moufida 
Published: July 2023

AbstractThere are a number of standards and frameworks for security risk assessment; however, it appears that their application and adaptation to real organisational practices are rather limited. This paper reports some results from inquiries into risk assessment practices of security professionals in Ireland. The key findings show a lack of consensus on basic terminology when it comes to defining risk and risk assessment. The interviewed security professionals have developed varied approaches in practice and rather refer to their intuition and previous experiences. While the paper focuses on Ireland, the lack of consensus regarding the definition, and use of security terminology and practices, especially in the area of security risk management, is not necessarily limited to Ireland.
