AbstractLoss-of-function mutations in MECP2 are associated to Rett syndrome (RTT), a severe neurodevelopmental disease. Mainly working as a transcriptional regulator, MeCP2 absence leads to gene expression perturbations resulting in deficits of synaptic function and neuronal activity. In addition, RTT patients and mouse models suffer from a complex metabolic syndrome, suggesting that related cellular pathways might contribute to neuropathogenesis. Along this line, autophagy is critical in sustaining developing neuron homeostasis by breaking down dysfunctional proteins, lipids, and organelles.Here, we investigated the autophagic pathway in RTT and found reduced content of autophagic vacuoles in Mecp2 knock-out neurons. This correlates with defective lipidation of LC3B, probably caused by a deficiency of the autophagic membrane lipid phosphatidylethanolamine. The administration of the autophagy inducer trehalose recovers LC3B lipidation, autophagosomes content in knock-out neurons, and ameliorates their morphology, neuronal activity and synaptic ultrastructure. Moreover, we provide evidence for attenuation of motor and exploratory impairment in Mecp2 knock-out mice upon trehalose administration. Overall, our findings open new perspectives for neurodevelopmental disorders therapies based on the concept of autophagy modulation.
High‐speed algorithm for fault detection and location in DC microgrids based on a novel time–frequency analysis
Authors: Poursaeed Amir Hossein , Namdari Farhad 
Published: October 2024

AbstractProtecting DC microgrids (DCMGs) from faults is critical due to the rapid current changes that occur in milliseconds. However, ensuring fast and accurate protection in DCMGs is more challenging than in AC systems. This study proposes a novel protection algorithm using traveling waves (TWs) for fault detection and localization. The high‐order synchrosqueezing transform (FSSTH) is applied to precisely identify TWs at the relay location. FSSTH offers a sharp time–frequency representation, enhancing the accuracy and speed of fault detection. This method can accurately detect transient phenomena like TWs in DCMGs, even with noise and variable fault resistance. By using the spectral envelope with FSSTH, ridges in time–frequency representations are extracted, improving fault diagnosis. The approach differentiates external from internal faults and recognizes fault direction by assessing TW polarity. Testing on two different DCMGs showed this algorithm's high efficiency and accuracy, with fault location errors ranging from 1 to 50 meters in low‐voltage and 13 to 64 meters in medium‐voltage DCMGs, even under challenging conditions like high resistance (up to 500 Ω) and low signal‐to‐noise ratio (5 dB). These results demonstrate the method's superior accuracy and robustness compared to existing techniques.
Design and implementation of a solar power optimizer for module level power electronics application
Authors: Allahverdinejad Babak , Ajami Ali , Banaei Mohamad Reza 
Published: October 2024

AbstractPartial shading on series‐connected photovoltaic (PV) panels in conventional PV systems results in lower harvested power. To resolve this, it is vital to utilize module level power electronics (MLPE) such as Solar Power Optimizers (SPOs). This paper introduced a non‐isolated common ground non‐inverting output voltage buck‐boost converter as an SPO. Proposed converter benefits from continuous input and output currents which has a significant role in designing SPOs. Having a quadratic gain, beside acceptable step‐down range are other features of the converter. Operating principle, design, steady‐state, small‐signal analysis, and dynamic performance of proposed converter are included. Proposed converter is compared with other buck‐boost converters in terms of voltage gain, voltage stresses, continuous input and output current, and output polarity. To validate the performance of introduced converter, experimental results for a prototype with input voltage 24 V, output voltage 72 V for step‐up and 15 V for step‐down modes are given and results are examined. The maximum efficiency of the prototype is 93% and 89% for step‐up and step‐down modes, respectively. To evaluate the effect of proposed SPO for extracting maximum available power from PVs, simulation results of a grid connected PV system with two series connected SPOs is discussed.

erläutert ein Fallbeispiel die Unterschiede. Während der primäre Gegenstand von
Balint-Gruppenarbeit die Reflexion von professionellen Beziehungen und ihren

Das „Flash“-Phänomen und die Semiotik: Die „Droge Arzt“ als
intersubjektiver Zeichenprozess
Authors: Herzog Philipp 
Published: October 2024

ZusammenfassungMichael und Enid Balint haben in ihrer Forschungsarbeit mit Hausärzten sehr bald
erkannt, dass das am häufigsten verordnete Medikament der Arzt selber ist. Ihre
Entdeckung des „Flash“-Phänomens führte zu einem grundlegend neuen Verständnis
der Wirkmacht der Arzt-Patient-Beziehung. Der Begriff beschreibt metaphorisch
das blitzartige, intuitive, gegenseitige Verstehen von Arzt und Patient. Obwohl
die Effekte der „Droge Arzt“ und des „Flash“ im Rahmen der Balint-Arbeit nicht
in Zweifel gezogen werden, bleibt der eigentliche Vorgang hinter Oberfläche des
Geschehens auch nach Jahrzehnten unklar. Diese Arbeit gibt eine kurze Einführung
in die die Semiotik und wendet sie auf zwei exemplarische Fallbeispiele aus der
Praxis an, um sie in ihrer kommunikativen Mikrostruktur zu erfassen und die
definitorische Unschärfe, die den Begriffen „Droge Arzt“ und „Flash“ innewohnt,
zu präzisieren.

Published: October 2024

AbstractReliable and reproducible measurement methods have been established, and
reference values are used in almost all scientific disciplines. Knowledge of
reference values is crucial to distinguish physiological from pathological
processes and, therefore, subsequently, for the clinical management of patients.
Image storage and documentation of measurements and normal findings should be
part of quality assurance in imaging. This paper aims to review the published
literature and provide current knowledge of sonographic measurements and
reference values of the pancreas. Moreover, the role of clinical influencing
factors such as age, gender, constitution, and ethnicity is also analyzed.

Published: October 2024

Abstract
Objective The aim of this study was to describe our experience using the transorbital endoscopic approach (TEA) in the frontal sinus and the step-by-step technique used.
Materials and Methods We reviewed the charts from adult patients who underwent management of frontal sinus lesions with TEA performed from 2017 to 2022.
Results Seven patients underwent eight surgeries for frontal sinus lesions using TEA in combination with the endoscopic transnasal approach (ETA), with the majority on the left side (5/8, 62.5%). The average age was 53.9 years, with six male patients and one female patient. Gross total resection (GTR) was achieved in all cases. The most common symptoms leading to surgery were headaches or a sensation of pressure in the forehead (5/8, 62.5%), followed by a decreased sense of smell (3/8, 37.5%), diplopia (3/8, 37.5%), proptosis (2/8, 20%), periorbital cellulitis (2/8, 20%), and decreased visual acuity (1/8, 12.5%). The most common etiology in this case series was mucocele (5/8, 62.5%), followed by osteoid osteoma (2/8, 20%), and inverted papilloma (1/8, 12.5%). The length of stay in all cases was 1 day. The most common complication was mild and transitory V1 numbness, which fully recovered after 6 months (5/8, 62.5%). The average follow-up period was 24.6 months (range of 3–48 months).
Conclusion Transoral Endoscopic Approach (TEA) demonstrated being a valuable complement to ETA approaches for treating frontal sinus lesions, especially in challenging regions. The transorbital approach is feasible and can safely achieve GTR for a variety of pathologies while effectively controlling symptoms and resulting in a 1-day hospital stay.
Nitrogen-Centered Radicals in Visible-Light-Promoted Reactions
Authors: Franco Francesca , Boselli Monica F. , Medici Fabrizio 
Published: October 2024

AbstractNitrogen-centered radicals (NCRs) have been known in the literature since the beginning of the 1900s, but only with the spread of photoredox catalysis, and in particular visible-light-mediated radical processes, has nitrogen-radical chemistry become more accessible via the in situ generation of such radicals under mild conditions. Historically, unlike their carbon counterparts, nitrogen radicals were not utilized widely in academia or industry due to a lack of efficient strategies for their production. Nowadays, NCRs are more established, and this graphical review highlights key publications from the literature, categorizing them by both the type of NCR and the type of reaction. Such nitrogen radicals can be divided into four different categories according to their electronic configuration, orbital structure and chemical behavior. Additionally, the reactivity of these radicals is mostly exploited via four main types of process: (i) intramolecular cyclization, (ii) intramolecular hydrogen atom abstraction, (iii) Norrish type I fragmentation, and (iv) intermolecular addition to π systems.

Published: October 2024

We employ a machine learning (ML)-guided framework to explore rare earth free magnetic materials, specifically focusing on Fe–Co–C ternary compounds for potential use in permanent magnets. Utilizing a specifically trained crystal graph convolutional neural network model, we efficiently screen a vast space of nearly a million substitutional structures to select 620 promising structures for further investigation by first-principles calculation. We predict five low-energy metastable Fe–Co–C compounds with formation energy less than 150 meV/atom above the convex hull. These compounds exhibit high magnetization (Js &gt; 1.0 T) and significant magnetic anisotropy (K1 &gt; 1.0 MJ/m3), making them promising candidates for permanent magnet applications. The phonon calculations indicate these compounds are dynamically stable. Our ML-guided framework demonstrates the utility of rapidly identifying novel materials with tailored magnetic properties.
Improving the efficiency of aerial surveys for monitoring North American beaver population dynamics
Authors: Kenyon Madeline , Dennison Catherine C. , Popescu Viorel D. 
Published: October 2024

Context The North American beaver (Castor canadensis) was extirpated from much of its range in the US in the 1800s due to fur trapping and change in land use. However, the species has recolonised much of its former range, including the US state of Ohio. Since 2013, the Ohio Division of Wildlife (ODOW) has monitored trends in beaver colony density via aerial surveys of 40 km × 40 km plots classified as low, medium, or high suitability based on the amount of wetland. Nonetheless, the current classification system may miss important correlates of beaver colony density. Aims Our study aimed to (1) identify predictors of beaver colony density (number of colonies inferred from aerial counts of lodges) across Ohio, and (2) develop a model-based classification system to improve the efficacy of monitoring efforts. Methods To predict beaver colony density in Ohio we used an aerial survey dataset of 54 plots (40 km × 40 km) collected by ODOW annually between 2013 and 2020, along with a suite of environmental, anthropogenic, and climate variables in a mixed effects modelling framework. Key results Beaver colony density was positively associated with wetland and reclaimed surface mine areas and inversely associated with the proportion of agricultural lands. There was a negative interaction between wetland and surface mines; in general, beaver colony density increased with wetland and surface mine area. However, in plots with wetland area >1000 ha, beaver colony density was weakly negatively associated with surface mine area. Using median and interquartile ranges of model-averaged predicted beaver colony density, we developed a new classification of low, moderate and high suitability for both the survey plots and the entire state of Ohio. We found that eastern Ohio had high suitability, while the central and western parts of the state had lower suitability for C. canadensis. Conclusions Our approach to identifying predictors for beaver colony density at broad spatial scales highlights the importance of reclaimed surface mines and wetlands for beaver populations, while the model-based habitat classification provides ODOW additional information for monitoring and beaver management decisions. Implications Improved C. canadensis monitoring at the landscape scale using habitat classifications that consider local conditions can both improve annual survey cost-effectiveness and facilitate the sustainable management of this recovering species.

Abstract
Rolling bearings are important mechanical elements for machines. Poly-ether-ether-ketone (PEEK) polymer is a suitable material for bearings in water and corrosive conditions because of its excellent water and chemical resistance. Some study had been examining rolling contact fatigue (RCF) tests in water; however, the competition between cracks propagation and wear on the surface of PEEK bearing in water was not clear. In the present study, in order to evaluate the crack propagation and wear process, RCF test with PEEK thrust bearings at 3750 [N] in water was carried out. The lengths of the surface cracks and the profiles of the grooves were observed at different number of cycles. In addition, so as to identify the cracks which cause the flaking, start-stop test was carried out. We found the surface crack, which was initially observed at 4.62×105 cycles, were gradually worn down and completely disappeared at 6.32×105 cycles. We concluded that rolling contact fatigue caused some surface cracks of PEEK to wear down in water condition.

Published: October 2024

Abstract
The surface morphology, compositions, microstructures, and chemical bond vibrations of potassium dihydrogen phosphate (KDP) crystals induced by nanosecond laser with different wavelengths, at different energy density are studied by scanning electron microscopy (SEM) and infrared spectroscopy (IR) techniques. SEM results showed that with the increase of laser energy density, the damage region on KDP surfaces presented three parts evidently. And the damage area increases nonlinearly with the laser energy density, accompanied by an increase in O element contents and a decrease in P and K element contents. Meanwhile, at the same energy density, the damage area induced by the 355 nm nanosecond laser is much larger than that by the 1064 nm nanosecond laser. Infrared spectrum results revealed that the laser irradiation leads to a break in hydrogen bonds and a dehydration of KDP crystals, in conjunction with a generation of P=O and P-H bonds. Moreover, with the increase of the laser energy density, the KDP crystal is damaged firstly, and then is annealed and repaired, finally is destroyed again. In addition, after irradiation at 10 J/cm2, all vibration modes of KDP crystals weaken or even disappear, and the sever damage occurs.

Published: October 2024

Abstract
Mesoporous silica, characterized by its adjustable pore size, uniform distribution, stable structure, and non-toxicity, is widely used as an encapsulating material for corrosion inhibitors. This study initially established that, compared to the high-temperature calcination method, the removal of surfactants via the solvent extraction method yields mesoporous silica with uniform size and better dispersibility. Results from N2 adsorption-desorption tests indicated that the mesoporous silica prepared by the solvent extraction method had an average pore diameter of 2.41 nm, a volume of 0.42 cc/g, and a specific surface area of 69.73 m2/g. SEM and TEM analyses showed that the BTA@MSNs nanoparticles synthesized via a one-step method were approximately 100 nm in size, whereas those prepared by the vacuum loading method were about 50 nm, both exhibiting ordered mesoporous structures. UV-vis spectrophotometry results revealed that the loading capacity of BTA in the nanoparticles produced by the one-step synthesis method was significantly lower than that in the BTA@MSNs nanoparticles prepared via the vacuum impregnation method.
Study on the influence of heat treatment process on the microstructure and hardness of carburized layer of 20CrMoH steel
Authors: Duan Luzhao , Gao Zhixin , Sun Zhiyan , Sun Caifeng , Sun Jiangbo , Zhang Peizi , Ren Shuai 
Published: October 2024

Abstract
In this paper, the effects of different carburizing quenching processes and tempering processes on the depth of the hardened layer and microstructure of 20CrMoH were studied by means of hardness analysis and SEM microstructure analysis. The results show that: when the quenching temperatures in the range of 820-880 °C, it has little effect on the depth of the hardened layer. And the hardness value at the same depth is at a considerable level, which is not affected by the quenching temperature. When the tempering temperature range is 150-280 °C, the tempering temperature has a great influence on the depth of hardened layer. And with the gradual increase of tempering temperature, the depth of hardened layer decreases gradually. Also the hardness value at the same depth from the edge shows a monotonous decreasing trend with the gradual increase of tempering temperature.

Abstract
The work established the patterns of a structural and phase transformations which occurs in the new steel of the 0,21C-1,0Mn-1,8Ni-0,3Cu-0,3Mo-0,03Ti-0,004B (%, mass) alloying system at different cooling rate. A thermokinetic diagram has been constructed. Laboratory samples of rolled products were manufactured and the mode of hardening of rolled sheets from a temperature of 860 ° C in water was tested to develop the industrial production of new steel using specialized equipment of the laboratory complex of LLC “EC Termodeform-MSTU”. The results of mechanical tests of rolled sheet samples after heat treatment showed that the steel under study in a hardened state has high strength characteristics in complex with increased impact strength at a test temperature of minus 70 °C: tensile strength σUTS = 1500 MPa, yield strength σ0.2 = 1150 MPa, relative elongation A5 = 12.5 %, hardness 429 HBW, impact strength KCV−70 = 50.3 J/cm2. This confirms its high quality and the possibility of using it for the production of heavily loaded mechanical engineering structures operated at low temperatures in the conditions of the Far North and the Arctic zone of the Russian Federation.
