Published: May 2024

Key Clinical MessageIn the context of diabetic ketoacidosis, clinicians should consider uncommon origins of infection, notably infective endocarditis. This is especially crucial when confronted with cases that recur persistently or exhibit resistance to treatment. This is a case of a diabetic patient with diabetic ketoacidosis admitted to our facility. A 35‐year‐old diabetic patient presented with DKA precipitated by mitral valve endocarditis. To our knowledge and according to the literature review, only one case of DKA precipitated by endocarditis has been reported in the past. This report highlights the importance of considering endocarditis as a possible etiology in patients presenting.

Key Clinical MessageTumor‐induced osteomalacia is a rare but potentially serious disease with nonspecific misguiding manifestations that can result in a wrong diagnosis and being treated for rheumatologic or other similar diseases. In patients with unexpected fractures, resistant musculoskeletal pains, and hypophosphatemia, this diagnosis should be considered by the physicians and approached through a complete history taking, physical exam laboratory, and radiologic evaluation to give the opportunity of on‐time treatment to the patient.AbstractTumor‐induced osteomalacia (TIO) is an uncommon mesenchymal tumor that results in disproportionate phosphorus excretion, primarily leading to bone‐related symptoms. Laboratory, imaging, and histopathological evaluation can confirm this pathologic condition. In this case, we present the history and subsequent clinical parts of a 50‐year‐old woman who presented with an unusual presentation of generalized musculoskeletal pains and a right ankle mass. Her disease was diagnosed with multidisciplinary evaluation and was approached by a surgical treatment. The patient was treated with total resection of the tumor, which led to complete resolution of musculoskeletal and metabolic abnormalities, which were resolved following total tumor resection. TIO is a paraneoplastic disease that results in abnormal secretion of phosphatonins, particularly fibroblast growth factor 23 (FGF23). This can cause hypophosphatemia, hyperparathyroidism, lower bone density, and increased risk of pathologic fractures. These tumors are mostly cured by surgical ± radiotherapy. The present study aims to provide insight into the fact that a TIO diagnosis is not always straightforward. However, in suspicious cases such as unexplained hypophosphatemia, it should be considered to prevent delayed diagnosis of the progressive pathology. The earlier treatment can prevent several complications and reduce the risk of mortality.

Published: May 2024

Key Clinical MessageArterial rupture is one of the rare but known and devastating complications of the angiogram, which can ultimately lead to loss of limb and life. Therefore, it is recommended that this complication be included in the consent form and that the operator and the logistics team be prepared for this scenario. Moreover, categorizing the patients based on risk factors to be more cautious during the procedure for high‐risk patients can be considered a reasonable strategy.AbstractOne of the rare but lethal complications of femoral artery catheterization for coronary angiography is arterial rupture, which can cause a range of negligible to massive retroperitoneal hemorrhage. This case presents a woman with unstable angina who underwent coronary catheterization. After arterial sheath placement, extravasation of blood from the right common iliac and lateral sacral arteries was seen, a diagnosis that has been reported rarely before. The bleeding was controlled with balloon inflation in the lateral sacral artery and a stent graft implantation in the right common iliac artery. The patient remained asymptomatic during the procedure and the short‐ and long‐term follow‐up. Interventional cardiologists and radiologists who access the femoral artery for any procedure should be aware of this possible event. Sometimes, this situation manifests with nonspecific symptoms such as weakness, lethargy, and pallor. Moreover, more logistical preparation and training are needed to overcome these unexpected conditions.
Small Molecule Oxidation Facilitated Seawater Splitting for Hydrogen Production: Opportunities and Challenges
Authors: Li Jingwei , Ping Jiang San 
Published: May 2024

AbstractDirect seawater splitting is an environment‐friendly and promising technology to replace freshwater electrolysis for hydrogen production. The challenge of seawater electrolysis lies in the competition between chloride oxidation reaction (CER) and oxygen evolution reaction (OER), as well as electrode corrosion and poisoning caused by chloride. Some small molecules have lower anodic electrocatalytic oxidation potentials compared to OER and CER, making them possible to substitute OER and/or CER in coupled electrolyzers not only to eliminate the electrode corrosion problem but also to significantly enhance the energy efficiency of seawater electrolysis. This article reviews the progress of such small molecule oxidation facilitated seawater electrolyzer. Starting with an overview of the key challenges in seawater electrolysis, this review introduces the fundamentals and advantages of the coupled seawater electrolyzers and discusses the strategies for anodic small molecule oxidation and cathodic hydrogen evolution reaction, including utilizing Cl− as a reactive medium, value‐added chemical synthesis, pollutants electrooxidation, and optimizing electrolyzers. Finally, the challenges and prospects of small molecule oxidation facilitated seawater splitting are summarized, aiming to provide impetus for research and development on coupled seawater electrolysis technologies.

Published: May 2024

AbstractAlthough the introduction of plastics has improved humanity's everyday life, the fast accumulation of plastic waste, including microplastics and nanoplastics, have created numerous problems with recent studies highlighting their involvement in various aspects of our lives. Upcycling of plastics, the conversion of plastic waste to high‐added value chemicals, is a way to combat plastic waste that is receiving increased attention. Herein, we describe a novel aerobic photochemical process for the upcycling of real‐life polystyrene‐based plastics into benzoic acid. A new process employing a thioxanthone‐derivative, in combination with N‐bromosuccinimide, under ambient air and 390 nm irradiation is capable of upcycling real‐life polystyrene‐derived products in benzoic acid in yields varying from 24–54 %.

Published: May 2024

AbstractLithium‐sulfur batteries (LSBs) have recently gained extensive attention due to their high energy density, low cost, and environmental friendliness. However, serious shuttle effect and uncontrolled growth of lithium dendrites restrict them from further commercial applications. As “the third electrode”, functional separators are of equal significance as both anodes and cathodes in LSBs. The challenges mentioned above are effectively addressed with rational design and optimization in separators, thereby enhancing their reversible capacities and cycle stability. The review discusses the status/operation mechanism of functional separators, then primarily focuses on recent research progress in versatile separators with purposeful modifications for LSBs, and summarizes the methods and characteristics of separator modification, including heterojunction engineering, single atoms, quantum dots, and defect engineering. From the perspective of the anodes, distinct methods to inhibit the growth of lithium dendrites by modifying the separator are discussed. Modifying the separators with flame retardant materials or choosing a solid electrolyte is expected to improve the safety of LSBs. Besides, in‐situ techniques and theoretical simulation calculations are proposed to advance LSBs. Finally, future challenges and prospects of separator modifications for next‐generation LSBs are highlighted. We believe that the review will be enormously essential to the practical development of advanced LSBs.
Rethinking student teachers' professional learning in Wales: Promoting reflection‐in‐action
Authors: Grigg Russell , Lewis Helen , Morse Miriam , Crick Tom 
Published: May 2024

AbstractNearly forty years ago, Stenhouse argued that the function of the curriculum was to stimulate teachers' everyday reflection about and learning from practice. This suggestion, alongside his support for teachers as researchers, aligns with the Welsh Government's commitment to build an evidence‐informed profession as part of ongoing major education system‐level reforms, including the implementation of the new Curriculum for Wales from September 2022. University initial teacher education (ITE) partnerships are playing an important role in building collaborative research capacity. This paper describes a case study of one such partnership which aims to promote research‐informed, reflective practice among its postgraduate primary student teachers. We use one of Stenhouse's principles of empirical study to frame our discussion of how student teachers' reflective practice is supported through brief conversations with their teacher educators (mentors) during lessons. Using a mixed methods approach, the findings show that student teachers value in‐the‐moment feedback. The intervention also helps them to question aspects of teaching and learning, although such reflection is at a technical level. Our study is useful for teacher educators who are interested in supporting reflective practice through coaching and mentoring. It also cautions school leaders and policymakers implementing major curriculum reforms not to lose sight of Stenhouse's view that ‘it is teachers who, in the end, will change the world of the school by understanding it’. The paper concludes by discussing the research implications in shaping emerging practice and policy in the context of ongoing system‐level reform and curriculum implementation in Wales, with potential applicability and portability to other contexts and jurisdictions.

Published: May 2024

SummaryIn a highly dense multiple‐input multiple‐output (MIMO) communication system, proper resource allocation is exceedingly challenging. The simultaneous selection of antennas at the base‐station (BS) and scheduling of users in an uplink multiple access channel (MAC) system add up to the signal processing load in the MIMO wireless system. The method chosen for combining the user scheduling and antenna selection must have a very low computational complexity. However, the exhaustive search algorithm (ESA), which achieves the best sum‐rate capacity in a MIMO‐MAC system, has a very high level of complexity. In this paper, we use a metaheuristic‐based optimization algorithms to optimize the sum‐rate capacity in a MAC system with significantly less computational complexity. First, we use the beluga whale optimization (BWO) metaheuristic method to solve the optimization problem. The BWO is a swarm‐based algorithm that draws inspiration from beluga whale behavior. An improved BWO (iBWO) is also presented and is utilized for the same optimization challenge. The proposed iBWO scheme improves the search capability of the algorithm and thereby ensures better exploration and exploitation capabilities of the beluga whales. We compare the performance of these algorithms with a standard differential evolution (DE) algorithm. The simulation results demonstrate that the proposed iBWO is a very competitive meta‐heuristic algorithm for solving optimization problems. The proposed iBWO algorithm achieves near optimal throughput in a MIMO‐MAC system. Also, the computational complexity related to the suggested optimization technique in a MIMO‐MAC system is found to be very less compared with the complexity related to ESA.
A comparison and development of methods for estimating shrub volume using drone‐imagery‐derived point clouds

Published: May 2024

AbstractShrub volume is used to calculate numerous, essential ecological indicators in rangeland ecosystems such as biomass, fuel loading, wildlife habitat, site productivity, and ecosystem structure. Field techniques for biomass estimation, including destructive sampling, ocular estimates, and allometric techniques, use shrub height and canopy widths to estimate volume and translate it to biomass with species‐specific allometric equations. These techniques are time‐consuming and pose challenges, including removal of plant material and training of observers. We compared canopy volume estimates from field‐based measurements with drone‐collected canopy volume estimates for seven dominant shrub species within mountain big sagebrush (Artemisia tridentata subsp. vaseyana) plant communities in southern Idaho, USA. Canopy height and two perpendicular width measurements were taken from 103 shrubs of varying sizes, and volume was estimated using a traditional allometric equation. Overlapping aerial images captured with a DJI Mavic 2 Professional drone were used to create a 3D representation of the study area using structure‐from‐motion photogrammetry. Each shrub was extracted from the point cloud, and volume was estimated using allometric and volumetric methods. The volumetric method, which involved converting point clouds to raster canopy height models with 2.5‐ and 5‐cm grid cells, outperformed the allometric method (R2 > 0.7) and was more reproducible and robust to user‐related variability. Drone‐estimated volume best‐matched field‐estimated volume (R2 > 0.9) for three larger species: A. tridentata subsp. tridentata, A. tridentata subsp. vaseyana, and Purshia tridentata. The volume of smaller shrubs (canopy widths <1 m) was slightly overestimated from drone‐based models. We argue that drone‐based models provide a suitable alternative to field methods, while having the added benefit of being less time‐consuming, with fewer limitations, and more easily scaled to larger study areas than traditional field techniques. Finally, we demonstrate a proof of concept for automating canopy volume estimates using point‐cloud‐based automatic shrub detection algorithms. These findings demonstrate that drone‐collected images can be used to assess shrub canopy volume for at least five upland sagebrush steppe shrub species and support the integration of drone data collection into rangeland vegetation monitoring.
Assessing the impacts of aquaculture on local fish communities using environmental DNA metabarcoding analysis

Published: May 2024

AbstractFish aquaculture potentially affects the local ecosystem through feed (leftovers) and feces. However, evaluation of its impacts on biodiversity, especially those of mobile organisms such as fish, is not straightforward. Here, we report a case study in which environmental DNA (eDNA) metabarcoding with MiFish universal primers for the 12S rRNA region of fish is used to detect and assess the impact of aquaculture on local fish communities. In Shizugawa Bay, Minamisanriku Town, Miyagi Prefecture, Japan, Oncorhynchus kisutch (coho salmon) is aquacultured in sea cages from November to July, but is absent from August to October. We conducted eDNA surveys in June, August, October, and December 2021 of water at depths of 5 m and 1 m above the bottom obtained from two sites, one approximately 100 m and the other approximately 2500 m from the nearest aquaculture site. The total number of operational taxonomic units (OTUs) detected was 122, with a maximum of 50 and a minimum of 10. With distance‐based redundancy analysis (dbRDA) and PERMANOVA applied to the eDNA‐based community compositional data, we detected a significant effect of the presence of O. kisutch aquaculture on fish biodiversity. The generalized linear model (GLM) applied to each detected OTUs indicated that the aquaculture was associated positively with Leucopsarion petersii (ice goby), and Oncorhynchus spp. and negatively with Chaenogobius annularis (forktongue goby). Environmental DNA metabarcoding surveys, combined with multivariate statics, are a promising tool to identify the dimension of biodiversity that human activity affects and would serve as a basic survey for sustainable use of the sea.

Authors: Yu Liu Jin , Inoue Shigeyoshi , Rieger Bernhard 
Published: May 2024

AbstractSilacycloheptatriene (silepin) species are novel silicon compounds reported in recent years. The interplay between the “closed” silepin and the “open” silylene form enables an enhanced stability of the low valent species while maintaining a high reactivity towards small molecules. In this work, two new silepins of similar structures to literature known compounds bearing modified silyl ligands are reported. A unique intramolecular activation of an aromatic hydrogen is found, and the respective formed hydrosilanes are characterized. We further synthesized iron(0) carbonyl complexes of known and new silepins in order to investigate their electronic properties relative to each other to gain more insight into substitution effect in such compounds.

Published: May 2024

AbstractIn recent years, the functionalization of 1,3‐butadiene has become an attractive strategy for constructing allyl compounds with molecular and structural complexity, and the current research focuses on synthetic chemistry and organic synthesis. Compared with the traditional synthesis method, the synthesis methods promoted by photochemistry or electrochemistry represent an environmentally friendly and mild strategy. In this review, the functionalization reactions of 1,3‐butadiene under photochemical/electrochemical processes in recent years are reviewed according to the classification of functionalization systems, with particular emphasis on the corresponding reaction mechanism, which lays a foundation for further exploration of new catalytic methods.
Channel changes over the last 200 years: A meta data analysis on European rivers

Published: May 2024

AbstractThe combined analysis of past evolutionary trajectories of channel morphology and temporal patterns of driving factors is fundamental to understanding present river conditions, supporting river management and evaluating future changes. Rivers in Europe underwent important channel changes during the Anthropocene in response to changing natural drivers and anthropogenic pressures. A considerable number of papers have been published on this topic, in the last decades. In this study, a comprehensive meta‐analysis on channel changes during the last 200 years in Europe was performed, aiming to provide quantitative information on the intensity of changes, to highlight regional scale similarities and dissimilarities in evolutionary morphological trajectories and to discuss the main causes of such changes. Based on a review, 102 papers were selected, addressing 145 channel reaches flowing through five main mountain ranges (Iberians, Alps, Apennines, Balkans and Carpathians) in the southern and eastern parts of Europe. The results show that active channel narrowing (between 26% and 36% on average) and incision (between 1 and 2 m) prevailed in most rivers between the 1800s and the 1950s, although widening was documented in some rivers of the Alps and the Apennines. Most multi‐thread reaches maintained their pattern until the mid‐20th century. Active channel changes accelerated during the 1950s–1990s (or 2000s) period, with channel narrowing up to 60% and channel incision up to 14 m. Multi‐thread patterns strongly decreased in frequency, with anabranching channels disappearing and single‐thread patterns becoming predominant. The cumulative effect of multiple and concomitant human pressures (gravel mining, channelisation and damming) was identified as the main driving factor for these accelerated changes. These findings must feed the public debate about preventing alterations of river ecosystems—exerted by anthropic disturbances—in a context of rapid economic development, especially in river systems still poorly altered and thus preserving wide, active and heterogeneous fluvial corridors.
Seeing is believing: Forecasting crude oil price trend from the perspective of images

Published: May 2024

AbstractIn this paper, we propose a novel imaging method to forecast the daily price data of West Texas Intermediate (WTI) crude oil futures. We use convolutional neural networks (CNNs) for future price trend prediction and obtain higher prediction accuracy than other benchmark forecasting methods. The results show that images can contain more nonlinear information, which is beneficial for energy price forecasting. Nonlinear factors also have a strong influence during drastic fluctuations in crude oil prices. In the robustness tests, we find that the image‐based CNN is the most stable approach and can be applied in various futures forecasting scenarios. In the prediction of low‐frequency models for high‐frequency data, the CNN method still retains considerable predictive power, indicating the possibility of transfer learning of our novel approach. By unleashing the power of the picture, we open up a whole new perspective for forecasting future energy trends.
