As one of the most popular ways to disseminate Internet content in the current era of media convergence, short videos have increasingly become part of people’s daily lives. This paper takes TikTok as the research object, focusing on the study of short video communication process. The research objective of this paper is to improve the international communication effect of short videos through data-driven analysis and strategy research on the law of international communication of short videos. Firstly, the key objective indicator system about international communication of short videos is constructed, the definition, selection and design logic of key objective indicators are introduced, the construction idea of the corresponding indicator system is proposed, and then the key objective indicator system about international communication of short videos and related data set are constructed. Secondly, an international communication network model for short videos is built.

The international short video communication network is constructed according to the key objective index system of international short video, and the key objective index system is used as nodes in the communication network, and the short video communication network is constructed by hierarchical relationship. Thirdly, the performance of the core theoretical model proposed in this paper is verified. The experimental results show that, the KOISPN-ATBiLSTM international communication network model of short videos has certain validity and advancement.

Published: June 2024

The application of beneficial microorganisms for corals (BMC) decreases the bleaching susceptibility and mortality rate of corals. BMC selection is typically performed via molecular and biochemical assays, followed by genomic screening for BMC traits. Herein, we present a comprehensive in silico framework to explore a set of six putative BMC strains. We extracted high-quality DNA from coral samples collected from the Red Sea and performed PacBio sequencing. We identified BMC traits and mechanisms associated with each strain as well as proposed new traits and mechanisms, such as chemotaxis and the presence of phages and bioactive secondary metabolites. The presence of prophages in two of the six studied BMC strains suggests their possible distribution within beneficial bacteria. We also detected various secondary metabolites, such as terpenes, ectoines, lanthipeptides, and lasso peptides. These metabolites possess antimicrobial, antifungal, antiviral, anti-inflammatory, and antioxidant activities and play key roles in coral health by reducing the effects of heat stress, high salinity, reactive oxygen species, and radiation. Corals are currently facing unprecedented challenges, and our revised framework can help select more efficient BMC for use in studies on coral microbiome rehabilitation, coral resilience, and coral restoration.

Published: June 2024

Sports records play a crucial role in understanding the limits of human achievement in sports. However, a thorough exploration of a comprehensive analysis of various sports records utilizing the existing statistical model has been lacking. This study introduces a framework for analyzing the integrated features and evolutionary trends of 23 sports records for men and women. It includes world records and intercontinental records from six continents, covering 6440 athletes from 2001 to 2020. Our findings indicate that human beings have not yet reached sports limits in athletic performance, suggesting a continuous improvement over time. Furthermore, we have investigated the contributions of our model’s parameters to the integrated features, emphasizing their robustness and convergence in handling data flow and information entropy. Additionally, our model underscores the significance of integrating various sports for ongoing advancement, in line with the Olympic motto “Together,” thereby promoting coordinated development.

Published: June 2024

Cancer-related cognitive impairment is a significant clinical challenge observed in patients with breast cancer, manifesting during or after treatment. This impairment leads to deteriorations in memory, processing speed, attention, and executive functioning, which profoundly impact patients' occupational performance, daily living activities, and overall quality of life. Grounded in the Symptom Science Model 2.0, this study investigates the contributing factors to Cancer-related cognitive impairment in breast cancer patients and develops a predictive nomogram for this demographic. Employing both univariate and multivariate logistic regression analyses, this investigation delineates the predictive factors influencing outcomes in breast cancer patients. A nomogram was constructed leveraging these identified predictive factors, accompanied by internal validation through bootstrap resampling methodology (1000 bootstrap samples). The efficacy of the predictive model was assessed by employing the Hosmer–Lemeshow goodness-of-fit test and calibration curves. The prevalence of cognitive impairment in breast cancer patients was identified to be 45.83%.Multivariate logistic regression analysis identified the independent predictors of Cancer-related cognitive impairment in breast cancer patients as place of residence, educational level, chemotherapy, benefit finding, post-traumatic growth, anxiety, fear of cancer progression, and fasting blood glucose levels. these factors were integrated into the nomogram. The Hosmer–Lemeshow goodness-of-fit test demonstrated that the prediction model was appropriately calibrated (χ2 = 11.520, P = 0.174). Furthermore, the model exhibited an area under the curve of 0.955 (95% CI 0.939 to 0.971) and a sensitivity of 0.906, evidencing its robust discriminative capacity and accuracy. Utilizing the Symptom Science Model 2.0 as a framework, this study comprehensively examines the multifaceted factors influencing Cancer-related cognitive impairment in breast cancer patients, spanning five critical domains: complex symptoms, phenotypic characterization, biobehavioral factors, social determinants of health, and patient-centered experiences. A predictive nomogram model was established, demonstrating satisfactory predictive accuracy and capability. This model is capable of identifying breast cancer patients with cognitive impairments with high precision. The findings furnish empirical evidence in support of the early detection, diagnosis, and intervention strategies for high-risk breast cancer patients afflicted with Cancer-related cognitive impairment.

Introducing the Intra-Individual Variability Hypothesis in Explaining Individual Differences in Language Development
Authors: Kautto Anna , Railo Henry , Mainela-Arnold Elina
Published: June 2024

Purpose:

Response times (RTs) are commonly used in studying language acquisition. However, previous research utilizing RT in the context of language has largely overlooked the intra-individual variability (IIV) of RTs, which could hold significant information about the processes underlying language acquisition.

Method:

We explored the association between language abilities and RT variability in visuomotor tasks using two data sets from previously published studies. The participants were 7- to 10-year-old children (
n
= 77).

Results:

Our results suggest that increased variability in RTs is associated with weaker language abilities. Specifically, this within-participant variability in visuomotor RTs, especially the proportion of unusually slow responses, predicted language abilities better than mean RTs, a factor often linked to language skills in past research.

Conclusions:

Based on our findings, we introduce the IIV hypothesis in explaining individual differences in language development. According to our hypothesis, inconsistency in the timing of cognitive processes, reflected by increased IIV in RTs, degrades learning different aspects of language, and results in individual differences in language abilities. Future studies should further examine the relationship between IIV and language abilities, and test the extent to which the possible relationship is causal.
Relationship between the shape of cross‐inductive loop coils and the induced voltage for position detection system
Authors: Jo Jeong‐Min , Lee Chang‐Young , Kim Jae Hee
Published: June 2024

Maglev trains require precise position data to control their propulsion systems. Specifically, sensing accurate phase based on position is necessary, for which cross‐inductive loop coils are used. To minimize phase errors, the envelope of the received voltage must be a sinusoidal wave depending on the position. This letter proposes the shapes of transmitting and receiving coils and presents, through simulation and experimentation, that the shapes of the transmitting and receiving coils and the induced voltage are in a convolution.

Published: June 2024

A new field plate (FP) is proposed for gallium nitride high‐electron‐mobility transistors (HEMTs). It features an innovative arcuate end (AE), which allows the induced charges that originally gathered at the FP end to diffuse over a wider area. Hence, not only is the electric field in the channel at the gate edge alleviated due to the induced charges, but also that concentrated at the FP end is reduced by means of AE. The simulation results indicate that by upgrading a source FP with AE, HEMT gains a 99% increase in breakdown voltage while remaining unaltered in specific on‐resistance. It also gets a 43.41% decrease in power loss during one cycle while maintaining the same breakdown voltage, which greatly contributes to enhance the efficiency of power electronic circuits.

Published: June 2024

An overall investigation of the electromagnetic force, vibration, and average torque of the Interior Permanent Magnet Synchronous Motors (IPMSM) in the dq model for electric propulsion ships is carried out, and the electromagnetic vibration characteristics of the PMSM under the vector control strategy is explored. Firstly, the space and frequency characteristics of the electromagnetic force of the dq model motor are derived using the Maxwell stress tensor method, and the influence of the dq‐axes magnetic field on the electromagnetic force under different loads is discussed in detail. Secondly, the finite element method is used to verify the influence of dq‐axes currents on motor electromagnetic force, vibration, and average torque. Finally, the experiments are conducted on an 8‐pole 48‐slot IPMSM, and the results are consistent with the theoretical analysis and simulation results. The results indicate that the electromagnetic vibration of the PMSM for electric propulsion ships increases with the increase of the current iq and decreases with the increase of the current id. The electromagnetic vibration of the motor can be reduced by selecting the appropriate dq‐axes current under the output torque constraint.
The IACOB project

Published: June 2024

Context. Blue supergiants (BSGs) are key objects for understanding the evolution of massive stars, which play a crucial role in the evolution of galaxies. However, discrepancies between theoretical predictions and empirical observations have opened up important questions yet to be answered. Studying statistically significant and unbiased samples of these objects can help to improve the situation.

Aims. We perform a homogeneous and comprehensive quantitative spectroscopic analysis of a large sample of Galactic luminous blue stars (a majority of which are BSGs) from the IACOB spectroscopic database, providing crucial parameters to refine and improve theoretical evolutionary models.

Methods. We derived the projected rotational velocity (υ sin i) and macroturbulent broadening (υmac) using IACOB-BROAD, which combines Fourier transform and line-profile fitting techniques. We compared high-quality optical spectra with state-of-the-art simulations of massive star atmospheres computed with the FASTWIND code. This comparison allowed us to derive effective temperatures (Teff), surface gravities (log 𝑔), microturbulences (ξ), surface abundances of silicon and helium, and to assess the relevance of stellar winds through a wind-strength parameter (log Q).

Results. We provide estimates and associated uncertainties of the above-mentioned quantities for the largest sample of Galactic luminous O9 to B5 stars spectroscopically analyzed to date, comprising 527 targets. We find a clear drop in the relative number of stars at Teff ≈ 21 kK, coinciding with a scarcity of fast rotating stars below that temperature. We speculate that this feature (roughly corresponding to B2 spectral type) might be roughly delineating the location of the empirical terminal-age main sequence in the mass range between 15 and 85 M⊙. By investigating the main characteristics of the υ sin i distribution of O stars and BSGs as a function of Teff, we propose that an efficient mechanism transporting angular momentum from the stellar core to the surface might be operating along the main sequence in the high-mass domain. We find correlations between ξ,υmac and the spectroscopic luminosity 𝓛 (defined as Teff4 / g). We also find that no more than 20% of the stars in our sample have atmospheres clearly enriched in helium, and suggest that the origin of this specific subsample might be in binary evolution. We do not find clear empirical evidence of an increase in the wind strength over the wind bi-stability region toward lower Teff.
Multiline study of the radial extent of SiO, CS, and SiS in asymptotic giant branch envelopes

Published: June 2024

Circumstellar envelopes around asymptotic giant branch (AGB) stars contain a rich diversity of molecules, whose spatial distribution is regulated by different chemical and physical processes. In the outer circumstellar layers, all molecules are efficiently destroyed due to interactions with interstellar ultraviolet photons. Here we aim to carry out a coherent and uniform characterization of the radial extent of three molecules (SiO, CS, and SiS) in envelopes around O- and C-rich AGB stars, and to study their dependence on mass-loss rate. To this end, we observed a reduced sample of seven M-type and seven C-type AGB envelopes in multiple lines of SiO, CS, and SiS with the Yebes 40 m and IRAM 30 m telescopes. The selected sources cover a wide range of mass-loss rates, from ~10−7 M⊙ yr−1 to a few times 10−5 M⊙ yr−1, and the observed lines cover a wide range of upper-level energies, from 2 K to 130 K. We carried out excitation and radiative transfer calculations over a wide parameter space in order to characterize the abundance and radial extent of each molecule. A χ2 analysis indicates that the abundance is usually well constrained while the radial extent is in some cases more difficult to constrain. Our results indicate that the radial extent of the molecules considered here increases with increasing envelope density, in agreement with previous observational findings. At high envelope densities of Ṁ/υ∞ > 10−6 M⊙ yr−1 km−1 s, SiO, CS, and SiS show a similar radial extent, while at low envelope densities of Ṁ/υ∞ < 10−7 M⊙ yr−1 km−1 s, differences in radial extent appear among the three molecules, in agreement with theoretical expectations based on destruction due to photodissociation. At low envelope densities, we find a sequence of increasing radial extent, SiS → CS → SiO. We also find a tentative dependence of the radial extent on the chemical type (O- or C-rich) of the star for SiO and CS. Interferometric observations and further investigation of the photodissociation of SiO, CS, and SiS should provide clarification of the situation in regards to the relative photodissociation radii of SiO, CS, and SiS in AGB envelopes and their dependence on envelope density and C/O ratio.
Bounds on galaxy stochasticity from halo occupation distribution modeling
Authors: Britt Dylan , Gruen Daniel , Friedrich Oliver , Yuan Sihan , Guachalla Bernardita Ried
Published: June 2024

The joint probability distribution of matter overdensity and galaxy counts in cells is a powerful probe of cosmology, and the extent to which variance in galaxy counts at fixed matter density deviates from Poisson shot noise is not fully understood. The lack of informed bounds on this stochasticity is currently the limiting factor in constraining cosmology with the galaxy–matter probability distribution function (PDF). We investigate stochasticity in the conditional distribution of galaxy counts along lines of sight with fixed matter density, and we present a halo occupation distribution (HOD)-based approach for obtaining plausible ranges for stochasticity parameters. To probe the high-dimensional space of possible galaxy–matter connections, we derive a set of HODs that conserve the galaxies’ linear bias and number density to produce REDMAGIC-like galaxy catalogs within the ABACUSSUMMIT suite of N-body simulations. We study the impact of individual HOD parameters and cosmology on stochasticity and perform a Monte Carlo search in HOD parameter space subject to the constraints on bias and density. In mock catalogs generated by the selected HODs, shot noise in galaxy counts spans both sub-Poisson and super-Poisson values, ranging from 80% to 133% of Poisson variance for cells with mean matter density. Nearly all of the derived HODs show a positive relationship between local matter density and stochasticity. For galaxy catalogs with higher stochasticity, modeling galaxy bias to second order is required for an accurate description of the conditional PDF of galaxy counts at fixed matter density. The presence of galaxy assembly bias also substantially extends the range of stochasticity in the super-Poisson direction. This HOD-based approach leverages degrees of freedom in the galaxy–halo connection to obtain informed bounds on nuisance model parameters and can be adapted to study other parametrizations of shot noise in galaxy counts, in particular to motivate prior ranges on stochasticity for cosmological analyses.

Published: June 2024

Context. Despite the identification of the smallest sugar molecule, glycolaldehyde (GA), in the interstellar medium (ISM), its mechanism of formation in the ISM is still not fully understood. A more profound understanding of the interstellar chemistry of GA and related molecules could provide insights into whether larger sugar molecules can also form and survive under such conditions.

Aims. The primary objectives of this research are to delve into the sugar formation mechanism in the ISM, especially in dark molecular clouds; unravel intricate details of H-atom-mediated reactions involving glyoxal (GO), GA, and ethylene glycol (EG); and identify intermediates playing potential roles in the formation of larger sugars or serving as intermediates in the destruction reaction paths of sugar molecules.

Methods. The study utilizes the para-H2 matrix isolation method with infrared (IR) spectroscopic detection and quantum chemical computations to investigate H-atom reactions of GO, GA, and EG at a low temperature.

Results. Several radical products were spectroscopically identified that might be key active species in the interstellar formation of larger sugar molecules.
The possible origin of three Apollo asteroids
Authors: Knežević N. , Todorović N.
Published: June 2024

Aims. We study the possible dynamical background of three Apollo asteroids: 3200 Phaethon, 2005 UD, and 1999 YC. The source regions under consideration are the asteroid families (2) Pallas, in the outer belt, and two inner-belt families (329) Svea and (142) Polana. We also aim to explain some of the contradictions in the literature in regards to the origin of Phaethon.

Methods. Our methodology relies on the precise dynamical mapping of several mean motion resonances (MMRs), which are considered the main transport channels. This approach allows the clear detection of chaotic structures in an MMR and efficent selection of test asteroids for diffusion. We tracked the orbital evolution of the selected particles over 5 million years and registered all their eventual entries into the orbital neighborhood of the asteroids 3200 Phaethon, 2005 UD and 1999 YC. We performed massive calculations for different orbital and integration parameters using Orbit9 and Rebound software packages.

Results. We observed possible connections between three targeted Apollo asteroids and asteroid families we considered as their sources. The (2) Pallas family has the highest chance of being the origin of targeted asteroids, and (142) Polana has the lowest. The amount of transported material largely depends on the integrator, the integration step, and even the choice of the initial epoch, though to a lesser extent. There is a systematic discrepancy between the results obtained with Orbit9 and Rebound regarding the efficiency of the transport, but they show good agreement over delivery times and dynamical maps. A non-negligible number of objects approached all three target asteroids, which could indicate that the breakup of the precursor body occurred during its dynamical evolution.
Future Green Mobile Communication Technology Facing the “Double Carbon” Goal
Authors: Feng Dengli
Published: June 2024

The goal of “double carbon” (namely “peak carbon dioxide emissions” and “carbon neutrality”) proposed by China for the first time is an important layout in the Tenth Five-Year Plan, and it is also the key goal to realize the green and sustainable development of mobile communication networks in the future, and it is also the foundation for China’s international carbon asset pricing right and the world carbon trading platform. Among them, the difficulty in realizing green communication lies in maintaining the growth of business volume. Reduce network energy consumption and carbon emissions. This paper studies the green communication technology from the perspective of energy saving and emission reduction on the mobile communication network side and the perspective of the integrated architecture of communication network and multi-energy energy network. The research results show that the key to realize green communication technology lies in the mutual matching of network resources, energy resources and business distribution, while the existing technology can only achieve one-way matching of network resources and business distribution. Or the one-way matching of energy resources and service distribution. Based on this, this paper proposes a native green grid architecture with communication, perception and energy fusion, which has the ability of energy perception and service perception, supports the two-way matching method of network resources, energy resources and service distribution, and realizes the continuous growth of service while significantly reducing the energy consumption and carbon emissions on the mobile communication network side by eliminating the randomness and suddenness of service distribution and energy distribution.
Design and Development a Software for Wear Measurement of Control Rod Guide Card Based on Machine Vision
Authors: Yang QianFei , Zhang Pengfei , Zeng Chenming , Zhang Yang
Published: June 2024

The control rod guide tube (CRGT) is used to protect the rod cluster control assembly (RCCA) from bending while providing guidance for the up and down movement of the RCCA. This ensures that the dropping time of the RCCA meets nuclear safety requirements and stops nuclear reactions within the specified time frame. During the up and down movement of the RCCA, the control rod guide cards (CRGC) may experience axial and vibration wear. If the wear is severe, the CRGC may lose its guiding function, resulting in serious problems such as delayed dropping time. In this paper, a machine vision method is proposed to measure the dimensions of the CRGC. Edge extraction, image rectification, and template matching are used to realize autonomous measurement of the CRGC based on its features. The developed measurement software has been used 5 times in domestic nuclear power plant overhauls and has detected 15 CRGTs that were close to the wear limit. This provided data support for the replacement of the CRGTs and effectively improved the quality of nuclear power operation.
Allocation Analysis of the Energy Storage System in Integrated Energy Systems Considering the Carbon Emissions and Cost

Published: June 2024

With the increasing integration of renewable energy into the power grid, the variability in its power generation has a growing impact on the stable energy supply of the system. The utilization of energy storage systems (ESSs) has been considered as an efficient approach to mitigate this effect. However, due to the different characteristics of different ESSs, it becomes an urgent issue about how to allocate the ESSs or combine different types of ESSs to maximize its performance. This study has constructed a new method to compare the performance of different ESSs, and analyze the strengths and weakness of mainstream ESSs with the real energy systems in Wuhan. It demonstrated that for short-term storage options such as superconducting energy storage, lithium-ion battery storage, and supercapacitor storage, larger capacities (2000kWh) yield better results. Conversely, the optimal allocation of long-term options like lead-acid batteries, flow batteries, and compressed air energy storage systems, depends on specific characteristics and wind patterns. Furthermore, this research also reveals that when considering the combination of involving both long-term (lead-acid battery) and short-term (superconducting battery) storages, it cannot simultaneously achieve optimal performance in terms of operating cost or carbon emissions reduction. For hybrid combinations such as supercapacitor-lithium-ion battery (short-term-short-term) or compressed air-energy-flow battery (long-term-long-term), it is crucial to ensure that the type with superior performance possesses maximum capacity.
Reliability dependent production-inventory model for redundancy allocation via fuzzy logic
Authors: Maji Anushri , Bhunia Asoke Kumar , Mondal Shyamal Kumar
Published: June 2024

This study deals with a reliability dependent production-inventory model in two scenarios: a redundancy allocation with crisp structure and the other with fuzzy logic. Here, a manufacturer purchases some raw-materials/components in variable cycles and arranges them as series-parallel system to produce a single item with production cost dependent on system reliability. In this model, a retailer gets the opportunity of warranty period and credit period offered by the manufacturer. Also, the retailer’s demand is dependent on system reliability, credit period and selling price. In the crisp model, the component reliability is exponentially dependent on known failure rate and failure time. However, there is no dependent relationship between these two parameters. Actually, the real world is full of uncertainty and these two parameters may depend on each other following some uncertain nature which can be expressed as fuzzy logic. So, in the fuzzy model, failure time has been considered as dependent on failure rate following fuzzy logic and these fuzzy relations are defuzzified by using three fuzzy inference techniques: Mamdani, Sugeno and Tsukamoto. Main goal of this article is to determine the optimum number of cycles and components to maximize manufacturer’s profit and system reliability with some constraints. The model is solved by using elitist non-dominated sorting genetic algorithm (NSGA-II) and some numerical examples closed to real-world have been executed. Comparative analyses are done for different cases; different fuzzy inference techniques and for active and mixed strategies. Finally, some sensitivity analyses and managerial insights are drawn.
Subcutaneous Washout Procedure (SWOP) zur Behandlung schwerwiegender

Copolyamid-Filler
Authors: Oster Katharina , Ring Andrej , Dellmann Niklas , Thomas Rosmaria , Zilakov Dimitrij , Witt Mathias
Published: June 2024

Hintergrund Neben operativen Verfahren zur Brust- und Gesäßaugmentation
besteht die Möglichkeit, mittels einer Injektion von Copolyamidfillern eine
Volumenzunahme des gewünschten Areals zu erreichen. Dieses Verfahren erfreut
sich insbesondere im asiatischen Raum großer Beliebtheit.

Patientin Eine 39-jährige Patientin hatte eine Gesäßaugmentation mit einem
Copolyamidfiller (Aquafilling) erhalten. Mit einer Zeitverzögerung von sechs
Jahren zeigten sich multiple Abszedierungen und eine Migration des Fillers, mit
furchsbauartiger Fistelgangbildung bis in die Oberschenkelmuskulatur. Es bestand
die Notwendigkeit einer wiederholten operativen Therapie.

Ergebnisse In dem demonstrierten Fall zeigen sich bei diesem Produkt
vorbekannte Komplikationen wie eine Fillermigration, eine Abszedierung und eine
chronische Infektion. Diese traten erst mit einer deutlichen Zeitverzögerung
auf. Eine vollstände Entfernung des Fillers ist nur mit dem umliegenden Gewebe
möglich. Eine operative Therapie mittels wiederholten Débridements und Gabe
eines intravenösen Breitspektrumantibiotikums sind aktueller Therapiestandard.
Die hier vorgestellte SWOP-Technik erscheint demgegenüber weniger invasiv und
weniger lokalrezidivträchtig.

Schlussfolgerung Die Gesäß- oder Brustaugmentation mit Copolyamidfillern
ist mit dem erheblichen Risiko einer chronischen Eiterung und Fistelbildung
verbunden, das bis zu einer Entstellung des Patienten führen kann.

research on dHL in Germany and further research approaches.

Methods A Scoping review based on the widely used methodological framework
of Arksey and O'Malley was conducted. The databases of PubMed, MEDLINE,
CINAHL, APAPsychArticles, SprinerLink and Livivo were searched. A search syntax
based on the topic was developed and adapted to the individual databases. The
full text of 27 enclosed citations was assessed in detail.

Results Research objectives on dHL in Germany mainly focus on studies to
measure dHL in (sub-)population(s), on the influence of dHL on certain
parameters as well as on the conceptual understanding of dHL in the German
context. The definition and measurement of dHL differs and reveals that no
common conceptual understanding exists. Recommendations for the promotion of dHL
are unconcrete but imply a conceptual further development, target-oriented
promotion measures and the integration of further actors of the healthcare
system.

Conclusions Findings imply further research especially on a common
understanding, effective measures, and a holistic approach to successfully
promote dHL in Germany.

Published: June 2024

A straightforward and efficient electrochemical method for the anodic oxidative selenenylation of 2-(2-arylallyl)phenols and a 2-(3-arylbut-3-en-1-yl)phenol with diselenides under ambient air conditions has been outlined. This method allows for the synthesis of selenyl-dihydrobenzofurans and a chromane featuring a sterically hindered tetrasubstituted carbon center, demonstrated through 25 examples with yields reaching up to 98%. Initial mechanistic investigations suggest the likely participation of pivotal seleniranium cation species in regulating the reactivity.

Hypospadias (HS) is a congenital defect that occurs due to defective androgenization. It is characterized by the aberrant location of the urinary meatus on the ventral aspect of the penis with various degrees of severity. The molecular mechanisms and genetic associations underlying the condition remain largely unknown. Existing literature revolves around surgical and medical management of the condition. Human chorionic gonadotropin pretreatment in HS is proposed to decrease the severity of the anomaly and improve the clinical outcome of surgery. The underlying mechanisms that drive these outcomes have not been explored. Few studies have explored the endocrine signaling and pathways which lead to the development of the condition. Hence, a prospective study was conducted to understand the same. Eighteen children with mid or proximal penile HS were included as cases, and nine children undergoing circumcision for phimosis (nonpathological) were included as controls. Serum samples from all these children and preputial skin samples taken during surgery were used in the analysis. The hormonal milieu was normal in all children in our cohort. A comparison of previously reported genes with our cohort sequencing revealed changes in several major pathways involved in cell proliferation and differentiation, cell signaling, angiogenesis, and immune response pathways. Compared with healthy controls, HS subjects had 152 differentially expressed genes. Of these, 93 genes were up-regulated, and 59 genes were found to be significantly down-regulated. The gene expression evaluation also showed changes in expression patterns in inflammatory genes and link RNAs, unlike previously reported genes.
Gender politics and Victorian literary representation of the body: a distant reading of the body in Charles Dickens’s works
Authors: Chen Houliang , Xu Qianwen
Published: June 2024

This paper analyses the nineteenth-century discourse around the human body. It examines two corpora: Charles Dickens’s works and contemporary writings. In both contexts, the body is observed through a detailed focus on its individual parts. This study employs a corpus-driven approach to investigate the vocabulary used to describe the body in these two corpora, providing complementary explanations to traditional close reading methods. The findings indicate that Victorian authors, including Dickens, tend to use nouns associated with time and space when representing the body, while also placing significant emphasis on codes of etiquette in the depiction of its physical actions. In Dickens’s corpus, nouns related to the body are influenced by gender ideology. Furthermore, a gender-based sub-corpus analysis, particularly focusing on verbs, highlights the disparities in agency between male and female bodies.

Foam targets have gained considerable importance over the last decade in laser–matter interaction. They find widespread applications such as in inertial confinement fusion and secondary sources for particles and radiation. At the same time, the advent of high repetition-rate laser systems, be they short-pulse in the tens of femtosecond regime or in the kilo-Joule nanosecond regime, calls for equally high repetition rate targetry systems. A well-established repetition-rate targetry system is the tape target. In this article, we present the successful marriage of a tape target delivery system with 3D-printed foam targets produced by two photon polymerization.

Published: June 2024

Precise control of dispersion output holds paramount significance across domains such as optical fiber communication, time stretching, and spectral interferometric ranging. In comparison to other dispersion elements, like prisms, gratings are widely applied in the field of dispersion control due to their advantages of broad spectral range, tunability, and high resolution. Moreover, linear dispersion is the most desired characteristic by designers in most cases. Here, we develop a dispersion model for grating groups to determine the optimal structural parameters for achieving linear dispersion in high-order grating arrays. Based on our model, we provide corresponding parameter selection methods that allow for quantitative design of the size and slope of output dispersion by adjusting input parameters such as angle, distance, and parallelism. Additionally, we experimentally establish a dispersion interferometry structure based on the grating ensemble that validates our proposed approach's capability for linear dispersion output (linearity better than 0.9998). We believe that our approach is universally significant and contributes to enhancing the performance of dispersion interferometric measurement systems, chirp amplification systems, and other related systems.

Published: June 2024

A comprehensive study on the photo-excited relaxation dynamics in semiconducting perovskite quantum dots (PQDs) is pivotal in realizing their extensive potential for optoelectronics applications. Among different competing photoinduced relaxation kinetics, energy transfer and charge transfer (CT) in PQDs need special attention, as they often influence the device efficacy, particularly with the donor–acceptor hybrid architecture. In this work, we explore a detailed investigation into photoinduced CT dynamics in mixed halide undoped CsPb(Br/Cl)3 and Mn2+ doped CsPb(Br/Cl)3 PQDs with a quinone molecule, p-benzoquinone (BQ). The energy level alignment of undoped PQDs with BQ allows an efficient CT, whereas Mn2+ doping reduces the CT efficiency, experiencing a competition between energy transfer from host to dopant and CT to BQ. The conductive atomic force microscopy measurements unveil a direct correlation with the spectroscopic studies by showing a significant improvement in the conductance of undoped PQDs in the presence of BQ, while an inappreciable change is observed for doped PQDs. A much-reduced transition voltage and barrier height in the presence of BQ further validate faster CT for undoped PQD than the doped one. Furthermore, Mn2+ doping in PQDs is observed to enhance their stability, showing better air and thermal stability compared to their undoped counterparts. These results reveal that doping strategy can regulate the CT dynamics in these PQDs and increase their stability, which will be beneficial for the development of desired optoelectronic devices with long-term stability.
