Published: May 2023

The early‐middle Neoproterozoic is thought to have witnessed significant perturbations to marine P cycling, in turn facilitating the rise of eukaryote‐dominated primary production. However, with few robust constraints on aqueous P concentrations, current understanding of Neoproterozoic P cycling is generally model‐dependent. To provide new geochemical constraints, we combined microanalytical data sets with solid‐state Nuclear Magnetic Resonance, synchrotron‐based X‐ray Absorption Near Edge Structure spectroscopy, and micro‐X‐ray Fluorescence imaging to characterize the speciation and distribution of P in Tonian shallow‐water carbonate rocks. These data reflect shallow water phosphate concentrations 10–100× higher than modern systems, supporting the hypothesis that tectonically‐driven influxes in P periodically initiated kinetically‐controlled CaCO3 deposition, in turn destabilizing marine carbonate chemistry, climate, and nutrient inventories. Alongside these observations, a new compilation and statistical analysis of mudstone geochemistry data indicates that, in parallel, Corg and P burial increased across later Tonian continental margins until becoming decoupled at the close of the Tonian, implicating widespread N‐limitation triggered by increasing atmospheric O2.

Published: May 2023

The aim of this review is to present a comprehensive overview of the feasibility of using transparent neural interfaces in multimodal in vivo experiments on the central nervous system. Multimodal electrophysiological and neuroimaging approaches hold great potential for revealing the anatomical and functional connectivity of neuronal ensembles in the intact brain. Multimodal approaches are less time-consuming and require fewer experimental animals as researchers obtain denser, complex data during the combined experiments. Creating devices that provide high-resolution, artifact-free neural recordings while facilitating the interrogation or stimulation of underlying anatomical features is currently one of the greatest challenges in the field of neuroengineering. There are numerous articles highlighting the trade-offs between the design and development of transparent neural interfaces; however, a comprehensive overview of the efforts in material science and technology has not been reported. Our present work fills this gap in knowledge by introducing the latest micro- and nanoengineered solutions for fabricating substrate and conductive components. Here, the limitations and improvements in electrical, optical, and mechanical properties, the stability and longevity of the integrated features, and biocompatibility during in vivo use are discussed.

Published: May 2023

Cancer-testis genes are involved in the occurrence and development of cancer, but the role of cancer-testis-associated lncRNAs (CT-lncRNAs) in hepatocellular carcinoma (HCC) remains to be explored. Here, we discovered a novel CT-lncRNA, LINC01977, based on the Genotype-Tissue Expression (GTEx) and The Cancer Genome Atlas (TCGA) databases. LINC01977 was exclusively expressed in testes and highly expressed in HCC. High LINC01977 levels correlated with poorer overall survival (OS) in individuals with HCC. Functional assays showed that LINC01977 promoted HCC growth and metastasis in vitro and in vivo. Mechanistically, LINC01977 directly bound to RBM39 to promote the further entry of Notch2 into the nucleus, thereby preventing the ubiquitination and degradation of Notch2. Furthermore, the RNA binding protein IGF2BP2, one of the m6A modification readers, enhanced the stability of LINC01977, resulting in its high level in HCC. Therefore, the data suggest that LINC01977 interacts with RBM39 and promotes the progression of HCC by inhibiting Notch2 ubiquitination and degradation, indicating that LINC01977 may be a potential biomarker and therapeutic target for HCC patients.
Antibiotic treatment can exacerbate biofilm-associated infection by promoting quorum cheater development

Published: May 2023

Quorum cheating, a socio-microbiological process that is based on mutations in cell density-sensing (quorum-sensing) systems, has emerged as an important contributor to biofilm-associated infection in the leading human pathogen Staphylococcus aureus. This is because inactivation of the staphylococcal Agr quorum-sensing system leads to pronounced biofilm formation, increasing resistance to antibiotics and immune defense mechanisms. Since biofilm infections in the clinic usually progress under antibiotic treatment, we here investigated whether such treatment promotes biofilm infection via the promotion of quorum cheating. Quorum cheater development was stimulated by several antibiotics used in the treatment of staphylococcal biofilm infections more strongly in biofilm than in the planktonic mode of growth. Sub-inhibitory concentrations of levofloxacin and vancomycin were investigated for their impact on biofilm-associated (subcutaneous catheter-associated and prosthetic joint-associated infection), where in contrast to a non-biofilm-associated subcutaneous skin infection model, a significant increase of the bacterial load and development of agr mutants was observed. Our results directly demonstrate the development of Agr dysfunctionality in animal biofilm-associated infection models and reveal that inappropriate antibiotic treatment can be counterproductive for such infections as it promotes quorum cheating and the associated development of biofilms.

Supercomputers are the most powerful computing machines available to society. They play a central role in economic, industrial, and societal development. While they are used by scientists, engineers, decision-makers, and data-analyst to computationally solve complex problems, supercomputers and their hosting datacenters are themselves complex power-hungry systems. Improving their efficiency, availability, and resiliency is vital and the subject of many research and engineering efforts. Still, a major roadblock hinders researchers: dearth of reliable data describing the behavior of production supercomputers. In this paper, we present the result of a ten-year-long project to design a monitoring framework (EXAMON) deployed at the Italian supercomputers at CINECA datacenter. We disclose the first holistic dataset of a tier-0 Top10 supercomputer. It includes the management, workload, facility, and infrastructure data of the Marconi100 supercomputer for two and half years of operation. The dataset (published via Zenodo) is the largest ever made public, with a size of 49.9TB before compression. We also provide open-source software modules to simplify access to the data and provide direct usage examples.

A systematic study integrating laboratory, analytical, and case study field trial was conducted to figure out the effective adsorbent that could be used for the removal of Congo red (CR) dye from industrial wastewater effluent. The ability of the zeolite (Z) to adsorb CR dye from aqueous solutions was evaluated after it was modified by the Cystoseira compressa algae (CC) (Egyptian marine algae). Zeolite, CC algae were combined together in order to form the new composite zeolite/algae composite (ZCC) using wet impregnation technique and then characterized by the aid of different techniques. A noticeable enhancement in the adsorption capacity of newly synthesized ZCC was observed if compared to Z and CC, particularly at low CR concentrations. The batch style experiment was selected to figure out the impact of various experimental conditions on the adsorption behavior of different adsorbents. Moreover, isotherms and kinetics were estimated. According to the experimental results, the newly synthesized ZCC composite might be applied optimistically as an adsorbent for eliminating anionic dye molecules from industrial wastewater at low dye concentration. The dye adsorption on Z and ZCC followed the Langmuir isotherm, while that of CC followed the Freundlich isotherm. The dye adsorption kinetics on ZCC, CC, and Z were agreed with Elovich, intra-particle, and pseudo-second-order kinetic models, correspondingly. Adsorption mechanisms were also assessed using Weber's intraparticle diffusion model. Finally, field tests showed that the newly synthesized sorbent has a 98.5% efficient in eliminating dyes from industrial wastewater, authorizing the foundation for a recent eco-friendly adsorbent that facilitate industrial wastewater reuse.

Published: May 2023

There seems to be no information on the incidence of injury and associated risk factors for academy football players in Ghana. We determine the risk factors associated with match and training injuries among male football players at an academy in Ghana. Preseason measurements of players’ height, weight, and ankle dorsiflexion (DF) range of motion (ROM) were measured with a stadiometer (Seca 213), a digital weighing scale (Omron HN-289), and tape measure, respectively. The functional ankle instability (FAI) of players was measured using the Cumberland Ankle Instability Tool (CAIT), and dynamic postural control was measured with the Star Excursion Balance Test. Injury surveillance data for all injuries were collected by resident physiotherapists throughout one season. Selected factors associated with injury incidence were tested using Spearman’s rank correlation at a 5% significance level. Age was negatively associated with overall injury incidence (r = − 0.589, p = 0.000), match (r = − 0.294, p = 0.008), and training incidence (r = − 0.314, p = 0.005). Previous injury of U18s was associated with training injuries (r = 0.436, p = 0.023). Body mass index (BMI) was negatively associated with overall injury incidence (r = − 0.513, p = 0.000), and training incidence (r = − 0.395, p = 0.000). CAIT scores were associated with overall injury incidence (n = 0.263, p = 0.019) and match incidence (r = 0.263, p = 0.029). The goalkeeper position was associated with match incidence (r = 0.241, p = 0.031) while the U16 attacker position was associated with training incidence. Exposure hours was negatively associated with overall injury incidence (r = − 0.599, p = 0.000). Age, BMI, previous injury, goalkeeper and attacker positions, ankle DF ROM, and self-reported FAI were associated with injury incidence among academy football players in Ghana.
The influence of tourism and hospitality students’ perceived effectiveness of outcome-based education on their VUCA skills
Authors: Guo Yanbing , Zhao Qiaoyan , Cao Zhe , Huang Shaosheng
Published: May 2023

The mismatch between supply and demand in the tourism and hospitality labor markets becomes increasingly serious in the past few years. The main reason for such a problem is that tourism and hospitality students are equipped with academic knowledge but lack VUCA skills. VUCA are the acronyms of volatility, uncertainty, complexity, and ambiguity. However, little research has explored the antecedent mechanism of tourism and hospitality students’ VUCA skills. Hence, the purpose of the present study is to clarify the leading factors that would enhance tourism and hospitality students’ perceived VUCA skills. This study collected data by distributing questionnaires to senior students majoring in tourism and hospitality management (THM) from five universities in China. The results show: First, students’ perceived the effectiveness of outcome-based education (PEOBE) has a significant effect on their perceived VUCA skills and self-concept including cognitive self-concept (CSC) and affective self-concept (ASC). Second, THM students’ CSC is positively related to their perceived VUCA skills. Finally, the relevance of ASC and students’ perceived VUCA skills was not significant. The present study further justified that PEOBE is the prepositive variable of THM students’ cognitive self-concept, supporting the linkage effect of “PEOBE → CSC → self-efficiency → perceived VUCA skills”. From the practical implications, this study focuses on OBE as the entry point to explore the antecedent mechanism of THM students’ perceived VUCA skills, supplying a basic formulation of educational reform policies for the administrative department of higher education around the world.

Published: May 2023

Comorbid glucose metabolism abnormalities are very common in patients with major depressive disorder (MDD), and glucose metabolism and lipid metabolism are closely related. However, there are few researches on the incidence and related factors of lipid metabolism abnormalities among MDD patients with comorbid glucose metabolism abnormalities. A cross-sectional study involving 1718 first-episode and drug-naïve (FEDN) MDD patients was conducted. The 17-item Hamilton Depression Scale (HAMD-17), Hamilton Anxiety Rating Scale (HAMA) and Positive and Negative Syndrome Scale (PANSS) positive subscale were utilized to evaluate depressive, anxiety and psychotic symptom, respectively. Serum thyroid function-related parameters, glucose- and lipid-metabolism parameters were measured. The prevalence of abnormal lipid metabolism was significantly higher in FEDN MDD patients with abnormal glucose metabolism than in those without abnormal glucose metabolism (P < 0.001). In MDD patients with abnormal glucose metabolism, TSH, FT3 and body mass index (BMI) levels were significantly higher in the abnormal lipid metabolism subgroup than in the non-abnormal lipid metabolism subgroup. Binary logistic regression analysis showed that TSH, FT3 and BMI were the influencing factors of abnormal lipid metabolism in MDD patients with abnormal glucose metabolism (all P < 0.05). MDD patients with abnormal glucose metabolism have a high prevalence of abnormal lipid metabolism. Moreover, abnormal glucose metabolism was an independent risk factor for abnormal lipid metabolism in patients with MDD. In addition, thyroid hormone function and BMI may contribute to the co-occurrence of abnormal lipid metabolism in MDD patients with abnormal glucose metabolism.
Plasticity in metabolism of maternal androgens in avian embryos

Published: May 2023

Mothers can influence offspring phenotypes by transferring non-genetic information to the young, which provides them with a flexible tool to adjust the developmental trajectory of the young in fluctuating environments. Mothers can differentially deposit their resources in the same reproductive attempt in relation to the offspring position in the sibling hierarchy. However, whether embryos from different positions can be plastic in their response to the maternal signals, potentially leading to a mother–offspring conflict, is yet unclear. We used Rock pigeons (Columba livia), that lay two egg clutches where maternal androgen levels in second laid eggs at oviposition are higher than in first laid eggs, and investigated the plasticity of embryonic metabolism of maternal androgens. We experimentally elevated androstenedione and testosterone levels in first eggs to that present in second eggs and measured the change in androgen levels and its main metabolites (etiocholanolone and conjugated testosterone) after 3.5 days of incubation. We found that eggs with increased androgens show a different degree of androgen metabolism depending either on the egg laying sequence or initial androgen levels or both. Our findings indicate that embryos have certain plasticity in response to maternal androgen levels depending on maternal signals.

Retinal Müller glia function as injury-induced stem-like cells in zebrafish but not mammals. However, insights gleaned from zebrafish have been applied to stimulate nascent regenerative responses in the mammalian retina. For instance, microglia/macrophages regulate Müller glia stem cell activity in the chick, zebrafish, and mouse. We previously showed that post-injury immunosuppression by the glucocorticoid dexamethasone accelerated retinal regeneration kinetics in zebrafish. Similarly, microglia ablation enhances regenerative outcomes in the mouse retina. Targeted immunomodulation of microglia reactivity may therefore enhance the regenerative potential of Müller glia for therapeutic purposes. Here, we investigated potential mechanisms by which post-injury dexamethasone accelerates retinal regeneration kinetics, and the effects of dendrimer-based targeting of dexamethasone to reactive microglia. Intravital time-lapse imaging revealed that post-injury dexamethasone inhibited microglia reactivity. The dendrimer-conjugated formulation: (1) decreased dexamethasone-associated systemic toxicity, (2) targeted dexamethasone to reactive microglia, and (3) improved the regeneration enhancing effects of immunosuppression by increasing stem/progenitor proliferation rates. Lastly, we show that the gene rnf2 is required for the enhanced regeneration effect of D-Dex. These data support the use of dendrimer-based targeting of reactive immune cells to reduce toxicity and enhance the regeneration promoting effects of immunosuppressants in the retina.

Revisiting blood pressure and body fluid status
Authors: Kitada Kento , Nishiyama Akira
Published: May 2023

Homeostasis of body fluid is a key component for maintaining health. An imbalance of body sodium and water causes various pathological states, such as dehydration, volume overload, hypertension, cardiovascular and renal diseases, and metabolic disorders. Conventional concepts regarding physiology and pathophysiology of body sodium and water balance have been established by several assumptions. These assumptions are that the kidneys are the master regulator of body sodium and water content, and that sodium moves inside the body in parallel with water. However, recent clinical and basic studies have proposed alternative concepts. These concepts are that body sodium and water balance are regulated by various organs and multiple factors, such as physical activity and the environment, and that sodium accumulates locally in tissues independently of the blood status and/or water. Various concerns remain unclear, and the regulatory mechanism of body sodium, fluid, and blood pressure needs to be readdressed. In the present review article, we discuss novel concepts regarding the regulation of body sodium, water, and blood pressure with a particular focus on the systemic water conservation system and fluid loss-triggered elevation in blood pressure.
Alive and kicking: A new QPE phase in GSN 069 revealing a quiescent luminosity threshold for QPEs

Published: May 2023

X-ray quasi-periodic eruptions (QPEs) are intense repeating soft X-ray bursts from the nuclei of nearby galaxies. Their physical origin is still largely unconstrained, and several theoretical models have been proposed ranging from disc instabilities to impacts between an orbiting companion and the existing accretion disc around the primary, or episodic mass transfer at pericentre in an extreme mass-ratio binary. We present here results from a recent XMM-Newton observation of GSN 069, the galactic nucleus where QPEs were first discovered. After about two years of absence, QPEs have reappeared in GSN 069, and we detect two consecutive QPEs separated by a much shorter recurrence time than ever before. Moreover, their intensites and peak temperatures are remarkably different, a novel addition to the QPE phenomenology. We study the QPE spectral properties from all XMM-Newton observations assuming QPEs to either represent an additional emission component superimposed on that from the disc, or the transient evolution of the disc emission itself. In the former scenario, QPEs are consistent with black-body emission from a region that expands by a factor of 2–3 during the individual QPE evolution with radius ≃5 − 10 × 1010 cm at QPE peak. In the alternative non-additive scenario, QPEs originate from a region with an area ∼6 − 30 times smaller than the quiescent state X-ray emission, with the smallest regions corresponding to the hottest and most luminous eruptions. The QPE reappearance reveals that eruptions are only present below a quiescent luminosity threshold corresponding to an Eddington ratio λthresh ≃ 0.4 ± 0.2 for a 106 M⊙ black hole. The disappearance of QPEs above λthresh is most likely driven by the ratio of QPE to quiescence temperatures, kTQPE/kTquiesc, approaching unity at high quiescent luminosity, making QPE detection challenging, if not impossible, above threshold. We briefly discuss some of the consequences of our results on the proposed models for the QPE physical origin.
Analysis of nonconforming IFE methods and a new scheme for elliptic interface problems
Authors: Ji Haifeng , Wang Feng , Chen Jinru , Li Zhilin
Published: May 2023

In this paper, an important discovery has been found for nonconforming immersed finite element (IFE) methods using the integral values on edges as degrees of freedom for solving elliptic interface problems. We show that those IFE methods without penalties are not guaranteed to converge optimally if the tangential derivative of the exact solution and the jump of the coefficient are not zero on the interface. A nontrivial counter example is also provided to support our theoretical analysis. To recover the optimal convergence rates, we develop a new nonconforming IFE method with additional terms locally on interface edges. The new method is parameter-free which removes the limitation of the conventional partially penalized IFE method. We show the IFE basis functions are unisolvent on arbitrary triangles which is not considered in the literature. Furthermore, different from multipoint Taylor expansions, we derive the optimal approximation capabilities of both the Crouzeix–Raviart and the rotated-Q1 IFE spaces via a unified approach which can handle the case of variable coefficients easily. Finally, optimal error estimates in both H1- and L2-norms are proved and confirmed with numerical experiments.

Published: May 2023

In 2021, the “Metaverse” concept became a big hit. As an exceptional media concept, the metaverse is closely related to the human sensory system, especially visual communication. Through the method of literature research and case analysis, combined with the recent publicity craze of “Liu Yexi” and from the perspective of the combination of the metaverse and short video, this paper argues that the richness and abstraction of the concept of metaverse require short video as a new form of communication. On this basis, the practical experience of “Liu Yexi” visual communication is analyzed from narrative logic, innovation leap, and visual spectacle. Then it is pointed out that the capitalization trend of artificial intelligence is the potential risk the metaverse may face in the long-term development.

The Phonetic Analysis of Z Rime Alternation Phenomena in Changyuan Dialect of Henan Province
Authors: Wei Mengyang , Wu Mengjiao
Published: May 2023

By analyzing the Z rime alternation phenomena in Changyuan Dialect of Henan Province, the present study argues that the phenomenon of one word having two different kinds of Z rime alternation forms in this dialect is due to it that the basic rime of the word preserves the Z rime alternation form that is formed before and after the sound change of the basic rime respectively. At the mean time, the development speed of Z rime alternation forms is slower than that of the basic rimes, so the Z rime alternation form preserves the glide of its corresponding basic rime of the early period and that’s exactly what leads to the differences between the glide of the present basic rime and that of the corresponding Z rime alternation form. Besides, the monophthongization phenomenon occurs between the main vowel and the [-u] ending in the compound final that is formed by sound combination during Z rime alternation process generally appears only in Jin language area of Northern Henan Province and doesn’t appear in Mandarin-speaking area of Henan Province.

Towards the correlation of working memory and incidental vocabulary learning
Authors: He Fang
Published: May 2023

Working memory means a lot in incidental vocabulary learning and retention. The present study examines the correlation between two types of working memory—complex working memory and phonological short-term memory—and incidental vocabulary learning from captioned videos. After conducting an empirical research to 125 young learners of English as a foreign language with two working memory tests: an operation span test, which measured complex working memory, and a non-word repetition test, which measured phonological short-term memory. It showed that complex working memory did not significantly predict the effects of captioning types on incidental vocabulary learning and retention. However, phonological working memory significantly affects incidental vocabulary learning and retention. The findings suggest that the role of working memory varies as a function of captioning types. Complex working memory and phonological short-term memory may have different predictive effects in incidental vocabulary learning and retention under different captioning types.
