Published: July 2023

AbstractBased on the requirements of resource conservation and environmental development, an important factor for paper‐based materials to be able to completely replace plastic materials in the packaging field is their ability to achieve high‐barrier performance, especially thermal barrier performance under extreme working conditions. In this paper, we report the preparation of paper‐based high‐barrier materials utilizing silicone modified acrylate emulsions as coatings, followed by a comprehensive analysis of their application performance. The test results show that the Cobb value reaches 15.71 g/m2, the Kit grade reaches up to 10, and can slow down the penetration rate of castor oil at 80°C within 24 h. Based on our characterization results, we have constructed a microscopic model of paper‐based barrier material and analyzed the barrier mechanism of silicone emulsion coated paper from a molecular perspective. These findings offer valuable insights into the preparation of paper‐based barrier materials, providing process methods and application data.

AbstractThe surface chemistry of Metal–Organic Polyhedra (MOPs) is crucial to their physicochemical properties because it governs how they interact with external substances such as solvents, synthetic organic molecules, metal ions, and even biomolecules. Consequently, the advancement of synthetic methods that facilitate the incorporation of diverse functional groups onto MOP surfaces will significantly broaden the range of properties and potential applications for MOPs. This study describes the use of copper(I)‐catalysed, azide–alkyne cycloaddition (CuAAC) click reactions to post‐synthetically modify the surface of alkyne‐functionalised cuboctahedral MOPs. To this end, a novel Rh(II)‐based MOP with 24 available surface alkyne groups was synthesised. Each of the 24 alkyne groups on the surface of the “clickable” Rh‐MOP can react with azide‐containing molecules at room temperature, without compromising the integrity of the MOP. The wide substrate catalogue and orthogonal nature of CuAAC click chemistry was exploited to densely functionalise MOPs with diverse functional groups, including polymers, carboxylic and phosphonic acids, and even biotin moieties, which retained their recognition capabilities once anchored onto the surface of the MOP.

Published: July 2023

AbstractFused‐benzoheptagon‐installed NiII porphyrins were synthesized by a protocol consisting of (2‐formyl)arylation at the meso‐position(s) of NiII porphyrins, conversion of formyl group to methoxyethene group by Wittig reaction, and final Bi(OTf)3‐catalyzed cyclization. The structures of these porphyrins have been revealed by X‐ray analysis. Owing to the installed heptagon ring(s), these porphyrins show curved structures with conformational flexibility. Dimer has been shown to have a small activation barrier for inversion and to capture C60 and C70 with large association constants with adjustable conformational changes.
A calibration method to stabilize estimation with missing data
Authors: Chen Baojiang , Yuan Ao , Qin Jing 
Published: July 2023

AbstractThe augmented inverse weighting (AIW) estimator is commonly used to estimate the marginal mean of an outcome because of its doubly robust property. However, the AIW estimator can be severely biased if both the propensity score (PS) and the outcome regression (OR) models are misspecified. One possible reason is that misspecification of the PS or OR model yields extreme values in these models, which can have a great influence on the marginal mean estimate. In this article, we propose a calibrated AIW estimator for the marginal mean, which can control the influence of these extreme values and provide a stable marginal mean estimator. The proposed estimator also enjoys the doubly robust property. We also extend this method to handle high‐dimensional covariates in PS and OR models. Asymptotic results are also developed. Extensive simulation studies show that the proposed method performs better in most cases than existing approaches by providing a more stable estimate. We apply this method to an AIDS clinical trial study.
Extending OCCI for an autonomous SLA negotiation strategy in federated clouds
Authors: Bouabdallah Raouia , Fakhfakh Fairouz 
Published: July 2023

SummaryEach cloud service provider provides only an interface of its own cloud infrastructure for enabling clients to use its cloud resources. However, there is a number of difficulties for cloud providers to ensure proper functioning. One of the main problems of a cloud provider is the lack of resources to support a huge number of on‐demand resources provisioning. Thus, resources cannot be distributed among different cloud providers since the federation is not the basic operation of the cloud provider. The most efficient way to overcome this problem is to extend the interface's cloud provider with an automatic negotiation to dynamically form the best agreement between the different cloud providers based on the service level agreement. In this article, we propose an extension for the Open Cloud Computing Interface which is the standardized interface for the cloud computing to support the automatic negotiation between the different cloud providers. To prove the efficiency and the effectiveness of our approach, we implement a prototype to evaluate the key presented in this article.
Misalignment tolerance improvement and high efficiency design for wireless power transfer system based on DDQ‐DD coil
Authors: Liu Yicheng , Zhang Junwei 
Published: July 2023

SummaryThis paper addresses misalignment tolerance improvement and high‐efficiency maintenance for wireless power transmission systems. Firstly, a receiving coil is designed according to Standard J2954, published by the Society of Automotive Engineers. Next, a DDQ transmitting coil is designed to accommodate a constrained operating space. The structure and parameters of the transmitting coils are determined to obtain a high coupling coefficient when offset occurs. Subsequently, an analysis is carried out to determine the relationship between the coupler magnetic fields and power transmission ability. A current phase control strategy is developed to deal with the mismatched magnetic fields, and a switching threshold is selected to obtain high power transmission efficiency. Finally, an experimental system is set up using the designed coil. The experimental results demonstrate that the system can maintain high efficiency even when lateral misalignment occurs in different directions. A maximum transmission efficiency of 89.63% is obtained, which validates the effectiveness of the proposed method.

Published: July 2023

AbstractSpecies boundaries are difficult to establish in groups with very similar morphology. As an alternative, it has been suggested to integrate multiple sources of data to clarify taxonomic problems in taxa where cryptic speciation processes have been reported. This is the case of the harvest mouse Reithrodontomys mexicanus, which has a problematic taxonomy history as it is considered a complex species. Here, we evaluate the cryptic diversity of R. mexicanus using an integrative taxonomy approach in order to detect candidate lineages at the species level. The molecular analysis used one mitochondrial (cytb) and two nuclear (Fgb‐I7 and IRBP) genes. Species hypotheses were suggested based on three molecular delimitation methods (mPTP, bGMYC, and STACEY) and cytb genetic distance values. Skull and environmental space differences between the delimited species were also tested to complement the discrimination of candidate species. Based on the consensus across the delimitation methods and genetic distance values, four species were proposed, which were mostly supported by morphometric and ecological data: R. mexicanus clade I, R. mexicanus clade IIA, R. mexicanus clade IIIA, and R. mexicanus clade IIIB. In addition, the evolutionary relationships between the species that comprise the R. mexicanus group were discussed from a phylogenetic approach. Our findings present important taxonomic implications for Reithrodontomys, as the number of known species for this genus increases. Furthermore, we highlight the importance of the use of multiple sources of data in systematic studies to establish robust delimitations between species considered taxonomically complex.

Published: July 2023

AbstractObjectiveEpilepsy is one of the widespread neurological illnesses, and about 20%–40% of epilepsy patients are pharmacoresistant. We aimed to assess the long‐term efficacy of subthalamic nucleus (STN) deep brain stimulation (DBS) for drug‐resistant epilepsy.MethodsWe included pharmacologically intractable epilepsy patients who had STN‐DBS at the Chinese People's Liberation Army General Hospital between June 2016 and December 2018. We retrospectively evaluated pre‐ and postoperative clinical outcomes, including seizure frequency, seizure type, anti‐seizure medication, cognitive function, anatomical target coordinates, stimulation parameters, and adverse events following the surgical procedure. Six patients with a mean follow‐up of 49.3 ± 10.2 months, were included.ResultsSeizure frequency decreased by an average of 64.0% after STN‐DBS at last year follow‐up (p = .046), and one patient (1/6) achieved seizure‐free status. For seizure type, anti‐seizure medication, and cognitive function, there were no significant differences between pre‐and post‐operation (p > .05). In terms of stimulation parameters, the pulse width, amplitude, and frequency were 58.3 ± 9.4 μs, 2.5 ± .7 V, and 122.5 ± 15.7 Hz, respectively. None of the patients showed normal electroencephalography during the electroencephalography reexamination. There were no surgery‐related complications, and chronic STN stimulation was generally well tolerated in five patients. However, one patient (1/6) had a difficulty of dyskinesia in the right arm.SignificanceIn conclusion, neuromodulation of the STN by DBS is a promising option for patients with pharmacologically intractable epilepsy, especially for whose epileptic zone originates mainly from the frontoparietal region and who are unsuitable for resective surgery. Further prospective multicenter studies with a larger sample size are necessary for further exploration.

AbstractDevelopmental and epileptic encephalopathy 45 (DEE45) is a neurogenetic disorder caused by heterozygous pathogenic variants of GABRB1, encoding the beta1 subunit of the GABA type A receptor. Only three infants with DEE45 have been reported so far, and a detailed description of the disease history of these patients is still lacking. We describe the clinical and genetic findings of a 21‐year‐old woman with DEE45 carrying a novel de novo GABRB1 mutation (c.841A>G, p.T281A). The patient presented at birth with hypotonia and focal apneic seizures evolving in a phenotype of epilepsy of infancy with migrating focal seizures that were refractory to antiseizure medications. Epileptic spasms partially responsive to steroid therapy appeared in the second year of life. Acquired microcephaly, profound mental retardation, and tetraparesis became evident with development. During childhood and adolescence, the epileptic phenotype evolved toward a Lennox–Gastaut Syndrome. Atypical absence status and clusters of tonic seizures occurred, often triggered by respiratory infections. The main strengths of this work are the identification of a novel pathogenic GABRB1 variant localized in the same transmembrane domain of a previously described mutation and the detailed description of the clinical trajectory of GABRB1‐related encephalopathy along 21 years of disease history.
Botulism mimicking Guillain‐Barre syndrome: The question of plasma exchange in an unusual case of acute paralysis

Published: July 2023

AbstractGuillain‐Barré syndrome (GBS) is an immune‐mediated polyradiculoneuropathy and the most common cause of acute flaccid paralysis worldwide. GBS classically presents with acute, progressive, ascending weakness, reduced to absent reflexes, and albuminocytological dissociation on cerebrospinal fluid (CSF) analysis. Botulism is a neurotoxin‐mediated acute descending flaccid paralysis with cranial nerve palsies and dysautonomia. Botulism in adults is caused by ingestion/inhalation of botulinum toxin or wound infection with Clostridium botulinum. Both GBS and botulism can rapidly precipitate respiratory failure; thus, prompt diagnosis and treatment are crucial to mitigate poor outcomes. Herein, we describe a case of botulism initially diagnosed as GBS given classic laboratory features, and describe the importance of careful consideration of the most appropriate therapeutic modalities in cases of acute flaccid paralysis, particularly regarding empiric administration of botulinum antitoxin and use of intravenous immune globulin in lieu of plasma exchange for potential GBS to prevent removal of antitoxin.

Published: July 2023

AbstractBackgroundHemoglobin A1c (HbA1c) levels are low in patients with hemolytic anemia, as HbA1c reflects mean erythrocyte age (MRBC). Erythrocyte creatine (EC) is a hemolytic indicator that also reflects MRBC. We previously reported an equation for estimating MRBC using EC (EC‐MRBC).AimsIn this study, EC‐MRBC was compared to the HbA1c level expressed in the International Federation of Clinical Chemistry and Laboratory Medicine units (iA1c) and to the iA1c/glycated albumin (GA) ratio to estimate MRBC.MethodsThis study included 238 subjects, including patients with hemolytic anemia and/or type 2 diabetes mellitus (T2DM).ResultsIn non‐diabetic individuals, both iA1c and iA1c/GA showed a strong positive correlation with EC‐MRBC (p < 0.0001). The equations to estimate iA1c‐MRBC and iA1c/GA‐MRBC derived from the regression equations between EC‐MRBC and iA1c, and EC‐MRBC and iA1c/GA in nondiabetic individuals were 1.45 × iA1c and 20.0 × iA1c/GA, respectively. iA1c‐MRBC and iA1c/GA‐MRBC in non‐diabetic individuals without hemolytic anemia were 57.6 ± 4.0 and 57.1 ± 6.4 days, respectively, and iA1c/GA‐MRBC in T2DM patients without hemolytic anemia was 56.0 ± 8.8 days.; no significant difference was seen in the comparisons.ConclusionsThe MRBC can be estimated using iA1c or iA1c/GA in non‐diabetic individuals, and iA1c/GA in T2DM patients.

Published: July 2023

AbstractWe theoretically investigate the feasibility of using a fiber laser source for high resolution and broadband coherent Raman scattering (CRS) spectroscopy/imaging employing spectral focusing technique. To accomplish this task, we have developed a simulation tool where the laser pulse parameters can be imported directly from any pulse propagation software using split‐step Fourier method to evaluate the spectral resolution and spectral coverage of CRS spectroscopy. Thus, the simulation tool can accommodate optical pulses of arbitrary shape and central wavelength, being also a user‐friendly and versatile open‐source software. We validate the numerical simulation tool by comparing its results with published theoretical and experimental data. We then use the tool to study the feasibility of using an all‐fiber laser source for high resolution CRS spectroscopy in both the C‐H window and the fingerprint region. This tool has a broad scope of applications in multiple fields where CRS spectroscopy is useful such as biomedicine, materials characterization, and biological imaging.

Published: July 2023

AbstractLand use land cover (LULC) changes are caused by natural and human alterations of the landscape that could largely affect forest biodiversity and the environment. The study aimed to analyze LULC change dynamics and driving forces in the western escarpment of the rift valley of the Gamo Zone, Southern Ethiopia. Digital satellite images, which are downloaded from USGS, were analyzed using ERDAS Imagine (14) and Arc GIS 10.2 software and supervised image classification was used to generate LULC classification, accuracy assessment, and Normalized Difference Vegetation Index (NDVI). Drivers of LULC change were identified and analyzed. Four land classes were identified such as forest, farmland, settlement, and water‐wetlands. Settlement and farmlands have increased by 8% and 6%, respectively. On the other hand, both forest and water‐wetlands decreased by aerial coverage of 9% and 5%, respectively. The overall accuracy of the study area was 92.86%, 94.22%, and 94.3% with a kappa value of 0.902, 0.92, and 0.922, respectively. NDVI values ranged between −0.42 and 0.73. Agricultural expansion (31.4%), expansion of settlement (25.7%) and Fuelwood collection and Charcoal production (22.9%) were the main driving forces that affected the biodiversity of the vegetation in the study area. Integrated land use and policy to protect biodiversity loss, forest degradation and climate changes are deemed necessary.
Soil C:N and C:P ratios positively influence colonization and development of incubated biocrusts in a sandy desert environment

Published: July 2023

AbstractOver the past few years, incubated biocrusts (IBSC)—the inoculation of soil/sand with cyanobacteria, moss, and lichen—have become one of the most promising biotechnological strategies for preventing soil erosion and restoring soil function in degraded drylands. Soil nutrient content (C, N, and P) is one of the key factors that influences IBSC colonization and development; however, the effects of soil C:N, C:P, and N:P stoichiometric ratios on the colonization and development of IBSC in desert environments are little known. We used four soil substrates, collected from four areas on the southeastern edge of the Tengger Desert, China, to incubate biocrusts. The four substrates differed in particle size and nutrient content. We flattened the dunes so their sand surfaces were level before covering them with soil substrates. We used a fully factorial design with four soil substrates and with and without biocrust additions, generating a total of 12 different treatments. The soil substrates differed in C, N, and P content and C:N, C:P, and N:P stoichiometric ratios. We measured IBSC coverage and thickness to establish relationships between IBSC characteristics and soil C:N, C:P, and N:P stoichiometric ratios. After 12 months of development, all treatments had significantly more cyanobacteria coverage, lichen coverage, and total coverage of IBSC than did control plots, which had little or no IBSC development. C:N and C:P ratios were significantly positively related to cyanobacteria coverage and total coverage of IBSC. Soil C:N and C:P ratios were mainly controlled by soil C; C limitation was greater than N and P limitation. Our study indicates that increasing initial soil substrate C content to improve C:N and C:P ratios will help the recovery of biocrusts and IBSC colonization. We demonstrate that stoichiometric ratios of soil should be a concern when assessing IBSC restoration treatments and when using IBSC to restore degraded land, especially at large scales.

AbstractDihydrogen (H2) is an important intermediate in anaerobic microbial processes, and concentrations are tightly controlled by thermodynamic limits of consumption and production. However, recent studies reported unusual H2 accumulation in permeable marine sediments under anoxic conditions, suggesting decoupling of fermentation and sulfate reduction, the dominant respiratory process in anoxic permeable marine sediments. Yet, the extent, prevalence and potential triggers for such H2 accumulation and decoupling remain unknown. We surveyed H2 concentrations in situ at different settings of permeable sand and found that H2 accumulation was only observed during a coral spawning event on the Great Barrier Reef. A flume experiment with organic matter addition to the water column showed a rapid accumulation of hydrogen within the sediment. Laboratory experiments were used to explore the effect of oxygen exposure, physical disturbance and organic matter inputs on H2 accumulation. Oxygen exposure had little effect on H2 accumulation in permeable sediments suggesting both fermenters and sulfate reducers survive and rapidly resume activity after exposure to oxygen. Mild physical disturbance mimicking sediment resuspension had little effect on H2 accumulation; however, vigorous shaking led to a transient accumulation of H2 and release of dissolved organic carbon suggesting mechanical disturbance and cell destruction led to organic matter release and transient decoupling of fermenters and sulfate reducers. In summary, the highly dynamic nature of permeable sediments and its microbial community allows for rapid but transient decoupling of fermentation and respiration after a C pulse, leading to high H2 levels in the sediment.
