Online Compositional Analysis of Complex Oligomers in Biomass Degradation by High-Pressure Flow-Through Reactor Coupled with High-Resolution Mass Spectrometry.

Online analysis of the composition and evolution of complex oligomeric intermediates in biomass degradation is highly desirable to elucidate the mechanism of bond cleavage and study the effect of conditions on the selective conversion of feedstocks. However, harsh reaction conditions and complicated conversion systems pose tremendous challenges for conventional, state-of-the-art analytical techniques. Herein, we introduce a continuous and rapid compositional analysis strategy coupling a high-pressure flow-through reactor with online high-resolution mass spectrometry, which enables the molecular-level characterization of most biomass-related products throughout the conversion for over 2 h. Catalytic depolymerization of one model compound was studied, and temperature-dependent data of over 50 intermediates as well as recondensation dimers and oligomers were obtained, which have rarely been reported in the literature. Thousands of products during the flow-through conversion of birch wood with molecular weights up to 1000 Da were presented, and 8 typical lignin dimers and oligomers with various interunit linkages were identified at the molecular level, demonstrating the potential to analyze more complicated systems far beyond conventional methods, especially for complex oligomers. The continuous evolutions of different components and typical products were unveiled for the first time, providing valuable insights into the investigation of the structure, composition, and decomposition mechanism of lignocellulose as well as the influence of reaction conditions. This method leads to the previously unattained ability to probe and reveal complicated chemical compositions in high-pressure reactions and can be applied to all other high-pressure heterogeneous aqueous reactions.

Was it all worth it? A graduating resident perspective on CBME

Background Our institution simultaneously transitioned all postgraduate specialty training programs to competency-based medical education (CBME) curricula. We explored experiences of CBME-trained residents graduating from five-year programs to inform the continued evolution of CBME in Canada. Methods We utilized qualitative description to explore residents’ experiences and inform continued CBME improvement. Data were collected from fifteen residents from various specialties through focus groups, interviews, and written responses. The data were analyzed inductively, using conventional content analysis. Results We identified five overarching themes. Three themes provided insight into residents’ experiences with CBME, describing discrepancies between the intentions of CBME and how it was enacted, challenges with implementation, and variation in residents’ experiences. Two themes – adaptations and recommendations – could inform meaningful refinements for CBME going forward. Conclusions Residents graduating from CBME training programs offered a balanced perspective, including criticism and recognition of the potential value of CBME when implemented as intended. Their experiences provide a better understanding of residents’ needs within CBME curricula, including greater balance and flexibility within programs of assessment and curricula. Many challenges that residents faced with CBME could be alleviated by greater accountability at program, institutional, and national levels. We conclude with actionable recommendations for addressing residents’ needs in CBME.

Time‐Resolved Oxidation State Changes Are Key to Elucidating the Bifunctionality of Perovskite Catalysts for Oxygen Evolution and Reduction

In a unified regenerative fuel cell (URFC) or reversible fuel cell, the oxygen bifunctional catalyst must switch reversibly between the oxygen reduction reaction (ORR), fuel cell mode, and the oxygen evolution reaction (OER), electrolyzer mode. However, it is often unclear what effect alternating between ORR and OER has on the electrochemical behavior and physiochemical properties of the catalyst. Herein, operando X‐ray absorption spectroscopy (XAS) is utilized to monitor the continuous and dynamic evolution of the Co, Mn, and Fe oxidation states of perovskite catalysts Ba0.5Sr0.5Co0.8Fe0.2O3‐δ (BSCF) and La0.4Sr0.6MnO3‐δ (LSM), while the potential is oscillated between reducing and oxidizing potentials with cyclic voltammetry. The results reveal the importance of investigating bifunctional catalysts by alternating between fuel cell and electrolyzer operation and highlight the limitations and challenges of bifunctional catalysts. It is shown that the requirements for ORR and OER performance are divergent and that the oxidative potentials of OER are detrimental to ORR activity. These findings are used to give guidelines for future bifunctional catalyst design. Additionally, it is demonstrated how sunlight can be used to reactivate the ORR activity of LSM after rigorous cycling.

Influence of continuous phase evolution of non-aqueous phase liquid on the retention and transport of coexistence perfluorooctanoic acid in saturated porous media

Non-aqueous phase liquid (NAPL) undergoing continuous evolution presents challenges in predicting the migration of co-contaminants within saturated porous media. This study explores the impact of the ongoing evolution of dimethyl phthalate (DMP-NAPL) on retention and transport of coexisting perfluorooctanoic acid (PFOA). The presence of PFOA facilitates the dispersion of free-phase DMP by mobilization and enhances the migration flux of solution phase through dissolution of both free and residual phase. The retardation of PFOA migration initially increases and then decrease as the evolution process continues. The retardation factor (R) demonstrates a negatively correlation with free-phase saturation (r = −0.987, p < 0.05), but a positively with residual-phase saturation (r = 0.948, p < 0.05). The primary factors controlling PFOA migration are its adsorption on the NAPL-water interface (fKi = 0 ∼ 58.51 %) and on solid surface (fKd = 41.18 ∼ 100 %). The contribution of partitioning to overall retention (fKn) remains consistently below 2 %, indicating limited partitioning into bulk DMP-NAPL. Dissolved DMP exhibits a slight retardation effect on low-concentration PFOA migration due to competitive adsorption. This study elucidates the migration characteristics of PFOA throughout the complete dynamic evolution of NAPL, providing valuable insights into contaminant transport in a multi-phase contaminated groundwater environment.

Surface Geological Evolution in the Chang'e 5 Landing Area (Em4 Unit) Revealed by a New Age‐Retrieving Method From Regression Learning

AbstractThe chronology function and production function have been widely used to derive the model ages of lunar mare regions from crater size‐frequency distributions. Challenges remain in homogenous counting area selection, crater saturation and crater rim identification. Geological unit‐based ages are also difficult to study the continuous surface evolution among adjacent areas. Using regression‐learning models, we have tried a new method on the Em4 unit of the Chang'e 5 landing area to explore a quantitative relationship between ages and surface morphometric expressions using texture features. Four features (Contrast, Energy, Entropy and Homogeneity), together with a stepwise linear model (SL) and a linear support‐vector‐machine model (LS), are well selected to produce a pixel‐level continuous age map of the Em4 unit. Mean age values of 1.75 ± 0.26 Ga and 1.69 ± 0.22 Ga obtained respectively from the two models are consistent with the ages of Chang'e 5 samples returned from this area. Both texture features and age maps are separated along the NW‐SE sinuous rilles (Rima Sharp and Rima Mairan). Comprehensively considering the geology, geomorphology, and newly retrieved ages of the study region, we have proposed a three‐stage evolution process for the Em4 unit. Our new age‐retrieving method is useful for obtaining a pixel‐level high‐resolution age map in the study region and has the potential to be widely used in other lunar mare areas.

Developments and current challenges in the process of cell culture-based seasonal influenza vaccine manufacture in Japan.

Seasonal influenza is an acute respiratory infection primarily caused by influenza A and B viruses, which circulate annually and cause substantial morbidity and mortality worldwide. Annual influenza vaccination is currently the most effective measure for preventing influenza and greatly reduces the risk of disease severity and the incidence of complications and death. Annual seasonal influenza vaccines are traditionally produced in Japan and many other countries using viruses propagated in embryonated chicken eggs. However, at present, the effectiveness of the seasonal influenza vaccines has some significant limitations, partly because of egg-adaptive mutations in the antigenic sites of the influenza virus haemagglutinin, which are caused by the continued evolution of seasonal influenza viruses. To overcome the limitations of egg-based influenza vaccine production, a mammalian cell culture-based influenza vaccine production system has been developed in Japan in the past decade as an alternative to the current production method. In this review, I have summarised the progress in the development of cell-based seasonal influenza vaccines and discussed the technological challenges encountered in the development of influenza vaccines.

SOLUȚII TEHNICE PENTRU ESTIMAREA BIOMASEI CONFORM CONCEPTULUI DE ACVACULTURĂ 4.0

Aquaculture, as a dynamic field, undergoes continuous evolution requiring continuous improvements in efficiency and new research efforts. Estimating fish biomass is an essential practice in the field of precision aquaculture, obtaining periodic information on fish biomass has been identified as an urgent need, considering the objective of optimizing daily feeding, controlling fish density and finally determining the optimal timing of harvesting. Conventional weighing methods, which often rely on manual procedures, have inherent challenges. Manual weighing processes are labor-intensive, requiring substantial time and human resources. Furthermore, manual handling of fish during weighing procedures induces considerable stress on aquatic organisms, potentially compromising their health and welfare. Consequently, there is a pressing need in the aquaculture industry to explore alternative weighing techniques that alleviate stress levels while increasing operational efficiency. In response to these challenges, contemporary research efforts have increasingly focused on the development of noninvasive and automated weighing methodologies. These innovations aim to simplify the weighing process, minimize human intervention and reduce the level of stress experienced by the fish population. However, estimating fish biomass without human intervention presents significant challenges because fish are sensitive and move freely in an environment where visibility, lighting, and stability are difficult to control. The paper analyzes technological solutions for biomass estimation according to the concept of Aquaculture 4.0.

In the post-95s and post-00s generation who have been &amp;quot;rectifying the workplace&amp;quot;, they have learned to make two-way choices and can even use various information channels to conduct &amp;quot;reverse interviews&amp;quot; with enterprises to ensure suitable employment opportunities. At present, the campus recruitment group has gradually entered the &amp;quot;post-2000&amp;quot; era. While AI companies need to face fierce market competition, how to attract and retain excellent young talents has become an important challenge. The article analyzes and summarizes the current situation of campus recruitment in contemporary AI enterprises, and provides suggestions for optimization solutions. It is hoped that this can solve the practical problems that contemporary AI companies face in campus recruitment and provide reference for the implementation of campus recruitment plans in related AI enterprises in the future.

SARS-CoV-2 Omicron: Viral Evolution, Immune Evasion, and Alternative Durable Therapeutic Strategies

Since the SARS-CoV-2 Omicron virus has gained dominance worldwide, its continual evolution with unpredictable mutations and patterns has revoked all authorized immunotherapeutics. Rapid viral evolution has also necessitated several rounds of vaccine updates in order to provide adequate immune protection. It remains imperative to understand how Omicron evolves into different subvariants and causes immune escape as this could help reevaluate the current intervention strategies mostly implemented in the clinics as emergency measures to counter the pandemic and, importantly, develop new solutions. Here, we provide a review focusing on the major events of Omicron viral evolution, including the features of spike mutation that lead to immune evasion against monoclonal antibody (mAb) therapy and vaccination, and suggest alternative durable options such as the ACE2-based experimental therapies superior to mAbs to address this unprecedented evolution of Omicron virus. In addition, this type of unique ACE2-based virus-trapping molecules can counter all zoonotic SARS coronaviruses, either from unknown animal hosts or from established wild-life reservoirs of SARS-CoV-2, and even seasonal alpha coronavirus NL63 that depends on human ACE2 for infection.

FLip mutations (L455F + F456L) in newly emerging VOI, JN.1: Its antibody and immune escape

During the COVID-19 pandemic, one of the biggest challenges was the continuous evolution of SARS-CoV-2 through various mutations. This has resulted in the emergence of several variants and subvariants. The escape mutations are reported as significant mutations in several variants and subvariants responsible for immune, antibody, and nAb escape. It has been reported that FLip mutations (L455F and F456L) in the spike RBD are responsible for immune evasion and antibody escape. Recently, WHO has included a new SARS-CoV-2 VOI, JN.1 lineage, a descendent of BA.2.86. The variant is reported from more than 41 countries, including France, the USA, Canada, the UK, Singapore, Sweden, and India. It contains FLip mutations in the spike protein in RBD (L455F and F456L). The risk assessment of the variant by WHO shows it has increased transmission, immune escape, and antibody escape due to the mutations. The article illustrated that FLip mutations in RBD (L455F and F456L) are responsible for augmented transmission and immune and antibody escape.

Evolutionary analyses of intrinsically disordered regions reveal widespread signals of conservation.

Intrinsically disordered regions (IDRs) are segments of proteins without stable three-dimensional structures. As this flexibility allows them to interact with diverse binding partners, IDRs play key roles in cell signaling and gene expression. Despite the prevalence and importance of IDRs in eukaryotic proteomes and various biological processes, associating them with specific molecular functions remains a significant challenge due to their high rates of sequence evolution. However, by comparing the observed values of various IDR-associated properties against those generated under a simulated model of evolution, a recent study found most IDRs across the entire yeast proteome contain conserved features. Furthermore, it showed clusters of IDRs with common "evolutionary signatures," i.e. patterns of conserved features, were associated with specific biological functions. To determine if similar patterns of conservation are found in the IDRs of other systems, in this work we applied a series of phylogenetic models to over 7,500 orthologous IDRs identified in the Drosophila genome to dissect the forces driving their evolution. By comparing models of constrained and unconstrained continuous trait evolution using the Brownian motion and Ornstein-Uhlenbeck models, respectively, we identified signals of widespread constraint, indicating conservation of distributed features is mechanism of IDR evolution common to multiple biological systems. In contrast to the previous study in yeast, however, we observed limited evidence of IDR clusters with specific biological functions, which suggests a more complex relationship between evolutionary constraints and function in the IDRs of multicellular organisms.
