Published: September 2023

AbstractIn recent years, researchers and practitioners have been exploring new methods for quality control, including image processing. The effective use of high‐volume image data can significantly improve the monitoring of production and service systems in terms of speed, accuracy, and cost. Adopting an image‐based approach is better than relying on operator‐based solutions, and it offers new perspectives for process monitoring. Image processing can involve extracting features to identify, classify, detect, and cluster. Although there are several transformations to extract features from images, the Fourier method cannot consider the concurrency of frequency and time data, and the wavelet method only considers two specific directions. In multidimensional transforms, the optimal method can provide more information using fewer coefficients. The contourlet transform has advantages such as multiresolution, localization, critical sampling, directionality, and anisotropy. This research investigates the advantages of applying the contourlet transform to images and using data in a generalized likelihood ratio control chart. The results show that this method is more accurate than others because it can examine various directions in images. The proposed methodology algorithm is also presented in this study.

AbstractSix years ago, a 60‐year‐old man presented to our hospital with a cough and sputum. Upon suspicion of nontuberculous mycobacterial (NTM) infection, he was followed up at our hospital. Because the abnormal shadows in the bilateral lung fields deteriorated slightly over 6 years, bronchoscopy was performed. Exophiala dermatitidis and Mycobacterium intracellulare were detected in the bronchial lavage fluid. The patient underwent follow‐up examinations without drug administration. Currently, the patient's condition remains stable. E. dermatitidis is regulatory found in the lungs of patients with cystic fibrosis, but only rarely is it found in respiratory samples from patients without cystic fibrosis. However, NTM complications have been reported more frequently in recent years. Due to the increasing number of NTM patients, E. dermatitidis pulmonary infections may also increase. Additional research is required to develop strategies for treating this infection.

Published: September 2023

AbstractSalmonid repeat spawners are precious individuals for wild populations due to their high fecundity and previous spawning experience, making them important in environmental policy. However, repeat spawners rarely exist above hydropower dams in regulated rivers as the mortality of post‐spawners (kelts) when passing through turbines during downstream migration is very high. To mitigate this problem, there are different technical solutions that potentially guide fish toward available fishways. Bubble barriers represent one alternative to costly physical guiding structures, but the efficiency of bubbles for guiding downstream migrating kelts has not been tested. In this study, we evaluate a 100 m long bubble barrier in guiding salmonids—both smolts and kelts—away from the main current and toward an alternative fishway in Ume River, a large regulated river in northern Sweden. We used both acoustic telemetry and sonar to measure the guiding effect of the bubble barrier for downstream migrating fish. We found that more than twice as many salmonids chose the alternative fishway when the bubble barrier was turned on. This was true both for smolts and kelts, suggesting that bubble barriers can be used to guide salmonids of different life stages in rivers with flow rates over 500 m3 s−1. Indeed, our study indicates that bubble barriers are low‐cost structures that could be rapidly applied in many regulated rivers to support salmonid migration.

Published: September 2023

AbstractSustainable development is one of the most significant issues of concern around the world today. Sustainable development goals cover natural resources, the environment, and human well‐being. It follows that eco‐efficiency (EE) and eco‐well‐being performance (EWP) are valid tools for measuring the level of different stages of sustainable development. This study uses a two‐stage super‐SBM model to gauge the EE and EWP of 281 cities in China from 2011 to 2019. The results show the following: (1) The national EE average is low, with M‐shaped “rising‐declining‐rising‐declining” fluctuation. The national EWP average is low, but there is a clear upward trend. (2) From a regional perspective, the best EE is in the eastern region, followed by the central and western regions, and the worst is in the northeastern region. The best EWP is in the western region, followed by the eastern and northeastern regions, and the worst is in the central region. (3) Among the 281 sample cities, approximately 12.8% are in the high EE‐high EWP development mode, 25.6% are in the high EE‐low EWP development mode, 18.2% are in the low EE‐high EWP development mode, and 43.4% are in the low EE‐low EWP development mode. Collectively, the three cities with the strongest sustainability are Shenzhen, Beijing, and Haikou, and the three weakest are Baise, Jinchang, and Baiyin. In addition, cities with larger populations tend to exhibit greater sustainability. These results provide the necessary reference for Chinese cities and cities worldwide in similar situations to formulate policies to improve sustainability.
Digital transformation for the sustainable development of firms: The role of green capability and green culture
Authors: Li Lei , Lin Jiabao 
Published: September 2023

AbstractLeveraging digital transformation to improve environmental performance is critical for sustainability. However, the underlying mechanism in the relationship between digital transformation and environmental performance remains unclear. Through the lens of IT‐enabled organizational capabilities, this study develops a moderated mediation model to examine the mechanisms and boundary conditions through which digital transformation affects environmental performance. Using a sample of Chinese agriculture firms, our findings reveal that digital transformation positively environmental performance through green capability, and this indirect effect is stronger when green culture is higher. Moreover, green culture moderates the relationship between digital transformation and green capability. Our theoretical explanation and empirical evidence contribute significantly to the literature by providing insights on how to leverage digital transformation initiatives to improve environmental performance.

Abstract
Serratia marcescens is a gram-negative bacterium found commonly in water and soil. Initially thought to be non-pathogenic, it is now recognised as an important cause of nosocomial and opportunistic infections. Skin infections are rare, but cases of S. marcescens causing ulcers, abscesses and necrotizing fasciitis have been reported. We report an unusual cutaneous presentation of S. marcescens in an immunosuppressed patient. A 77-year-old man under review for non-melanoma skin cancer in the context of a previous cardiac transplant, presented with an asymptomatic scalp eruption. Immunosuppressive medications included ciclosporin 90 mg twice daily (2.5 mg/kg/day) and mycophenolate mofetil 1 g twice daily. Physical examination revealed well-defined annular and polycyclic patches with brownish crusting across his scalp. Bacterial culture demonstrated a heavy growth of Staphylococcus aureus sensitive to flucloxacillin. The patient was treated with 7 days of flucloxacillin 500 mg four times daily. Despite this, the eruption extended. Skin biopsy demonstrated epidermal spongiosis, florid dermal inflammatory cell infiltrate and abundant bacteria and neutrophils in the parakeratotic crust. Fungal stains were negative as was direct immunofluorescence. Repeat culture demonstrated heavy growth of S. marcescens sensitive to ciprofloxacin. The patient was treated with 10 days of oral ciprofloxacin 500 mg twice daily along with 1% hydrogen peroxide cream topically with significant clinical improvement. Microbiological review indicated that a gram-negative organism was present in the initial scalp swab. In addition, S. marcescens had been detected previously on a skin swab from a recent transient eruption on the torso. Further, a heavy growth of a coliform bacillus was demonstrated in a similar eruption on the chest in 2013. It was concluded that the patient was likely colonised with S. marcescens which appeared to have caused recurrent superficial skin infections over several years. We report this case to highlight an unusual clinical presentation of cutaneous S. marcescens infection. This should be considered in the differential diagnosis of skin eruptions in immunocompromised patients. Clinical information detailing a patient’s immunosuppressed state must be supplied on microbiology requests to allow accurate interpretation of results, and consideration of organisms which may otherwise be overlooked or considered contaminants.

Compounds 3 c and 5 b, demonstrated potent CDK5 inhibitory activity with IC50=0.36±0.02 and 0.226±0.01 μM, respectively compared to roscovitine of IC50 value 0.149±0.007 μM. Compound 5 b also cause a significantly increased the percentage of cells at phases in S by 1.2 fold, compared to untreated cells. It was found that downregulation of Bcl2 expression by 3 and 6 folds for 3 c and 5 b, respectively than that the control in breast cell. In addition, examination of the induction of apoptosis by 5 b demonstrated that compound 5 b significantly increased the early and late apoptotic ratio by about 65 and 66 folds, respectively, proving that compound 5 b significantly induces apoptotic by 34.5 %. Moreover, the pharmacokinetic properties of 3 c and 5 b were predicted using ADME calculations, which revealed that they inhibit some CYP450 enzymes in the liver.

Authors: Dantsu Yuliya , Zhang Wen 
Published: September 2023

AbstractWe report here for the first time the synthesis of a novel 2′‐methoxy‐modified L‐cytidine analog and its phosphoramidite, as well as its incorporation into oligonucleotides via solid‐phase synthesis. Our measure the thermostability of the modified L‐nucleic acids by UV‐melting studies, and find out the 2′‐methoxy‐derivatization enhances the thermostability of the L‐duplexes. Consistent with the thermostability result, our X‐ray crystal structure study reveals that the 2′‐methoxy‐L‐deoxycytidine forms the Watson‐Crick base pair with L‐guanosine virtually as the mirror‐image fashion of native pair. This novel chemically modified L‐cytidine provides a useful biochemical and structural strategy to create mirror‐image nucleic acid molecules with expanded functionalities.

Published: September 2023

AbstractTwins in crystal defect, one of the significant factors affecting the physicochemical properties of semiconductor materials, are applied in catalytic conversion. Among the catalysts serving for photocatalytic water splitting, Zn1−xCdxS has become a hot‐point due to its adjustable energy band structure. Via limiting mass transport to control the release rate of anions/cations, twin Zn1−xCdxS solid solution is prepared successfully, which lays a foundation for the construction of other twin crystals in the future. On twin Zn1−xCdxS, water tends to be dissociated after being adsorbed by Zn2+/Cd2+ at twin boundary, then the fast‐moving electrons at twin boundary quickly combine with the protons already attached to S2− to form hydrogen. According to the theoretical calculation, not only the intracrystalline electron mobility, but also the extracrystalline capacity of water‐adsorption/dissociation and proton‐adsorption on the twin boundary are superior to those of the counterpart plane in defect‐free phase. The synthetic twin Zn1−xCdxS apparent quantum efficiency of photocatalysis water splitting for hydrogen reached 82.5% (λ = 420 nm). This research opens up an avenue to introduce twins in crystals and it hopes to shed some light on photocatalysis.

Published: September 2023

AbstractMetal‐free carbon‐based materials have gained recognition as potential electrocatalysts for the oxygen reduction reaction (ORR) in new environmentally‐friendly electrochemical energy conversion technologies. The presence of effective active centers is crucial for achieving productive ORR. In this study, we present the synthesis of two metal‐free dibenzo[a,c]phenazine‐based covalent organic frameworks (DBP‐COFs), specifically JUC‐650 and JUC‐651, which serve as ORR electrocatalysts. Among them, JUC‐650 demonstrates exceptional catalytic performance for ORR in alkaline electrolytes, exhibiting an onset potential of 0.90 V versus RHE and a half‐wave potential of 0.72 V versus RHE. Consequently, JUC‐650 stands out as one of the most outstanding metal‐free COF‐based ORR electrocatalysts report to date. Experimental investigations and density functional theory calculations confirm that modulation of the frameworks' electronic configuration allows for the reduction of adsorption energy at the Schiff‐base carbon active sites, leading to more efficient ORR processes. Moreover, the DBP‐COFs can be assembled as excellent air cathode catalysts for zinc‐air batteries (ZAB), rivaling the performance of commercial Pt/C. This study provides valuable insights for the development of efficient metal‐free organoelectrocatalysts through precise regulation of active site strategies.

Published: September 2023

AbstractThe semiconductor industry occupies a crucial position in the fields of integrated circuits, energy, and communication systems. Effective mass (mE), which is closely related to electron transition, thermal excitation, and carrier mobility, is a key performance indicator of semiconductor. However, the highly neglected mE is onerous to measure experimentally, which seriously hinders the evaluation of semiconductor properties and the understanding of the carrier migration mechanisms. Here, a chemically explainable effective mass predictive platform (CEEM) is constructed by deep learning, to identify n‐type and p‐type semiconductors with low mE. Based on the graph network, a versatile explainable network is innovatively designed that enables CEEM to efficiently predict the mE of any structure, with the area under the curve of 0.904 for n‐type semiconductors and 0.896 for p‐type semiconductors, and derive the most relevant chemical factors. Using CEEM, the currently largest mE database is built that contains 126 335 entries and screens out 466 semiconductors with low mE for transparent conductive materials, photovoltaic materials, and water‐splitting materials. Moreover, a user‐friendly and interactive CEEM web is provided that supports query, prediction, and explanation of mE. CEEM's high efficiency, accuracy, flexibility, and explainability open up new avenues for the discovery and design of high‐performance semiconductors.

Published: September 2023

AbstractChemically inert organic networks exhibiting electrical conductivity comparable to metals can advance organic electronics, catalysis, and energy storage systems. Covalent–organic frameworks (COFs) have emerged as promising materials for those applications due to their high crystallinity, porosity, and tunable functionality. However, their low conductivity has limited their practical utilization. In this study, copper‐coordinated‐fluorinated‐phthalocyanine and 2,3,6,7‐tetrahydroxy‐9,10‐anthraquinone‐based COF (CuPc‐AQ‐COF) films with ultrahigh conductivity are developed. The COF films exhibit an electrical conductivity of 1.53 × 103 S m−1 and a Hall mobility of 6.02 × 102 cm2 V−1 s−1 at 298 K, reaching the level of metals. The films are constructed by linking phthalocyanines and anthraquinones through vapor‐assisted synthesis. The high conductivity properties of the films are attributed to the molecular design of the CuPc‐AQ‐COFs and the generation of high‐quality crystals via the vapor‐assisted method. Density functional theory analysis reveals that an efficient donor–acceptor system between the copper‐coordinated phthalocyanines and anthraquinones significantly promotes charge transfer. Overall, the CuPc‐AQ‐COF films set new records of COF conductivity and mobility and represent a significant step forward in the development of COFs for electronic, catalytic, and electrochemical applications.

AbstractTwo‐dimensional metal‐organic frameworks (MOFs) occupy a special place among the large family of functional 2D materials. Even at a monolayer level, 2D MOFs exhibit unique sensing, separation, catalytic, electronic, and conductive properties due to the combination of porosity and organo‐inorganic nature. However, lab‐to‐fab transfer for 2D MOF layers faces the challenge of their scalability, limited by weak interactions between the organic and inorganic building blocks. Here, comparing three top‐down approaches to fabricate 2D MOF layers (sonication, freeze‐thaw, and mechanical exfoliation), The technological criteria have established for creation of the layers of the thickness up to 1 nm with a record aspect ratio up to 2*10^4:1. The freezing‐thaw and mechanical exfoliation are the most optimal approaches; wherein the rate and manufacturability of the mechanical exfoliation rivaling the greatest scalability of 2D MOF layers obtained by freezing‐thaw (21300:1 vs 1330:1 aspect ratio), leaving the sonication approach behind (with a record 900:1 aspect ratio) have discovered. The high quality 2D MOF layers with a record aspect ratio demonstrate unique optical sensitivity to solvents of a varied polarity, which opens the way to fabricate scalable and freestanding 2D MOF‐based atomically thin chemo‐optical sensors by industry‐oriented approach.

Published: September 2023

SummaryEmotion recognition is challenging for understanding people and enhances human–computer interaction experiences, which contributes to the harmonious running of smart health care and other smart services. In this paper, several kinds of speech features such as Mel frequency cepstrum coefficient, pitch, and formant were extracted and combined in different ways to reflect the relationship between feature fusions and emotion recognition performance. In addition, we explored two methods, namely, support vector machine (SVM) and deep belief networks (DBNs), to classify six emotion status: anger, fear, joy, neutral status, sadness, and surprise. In the SVM‐based method, we used SVM multi‐classification algorithm to optimize the parameters of penalty factor and kernel function. With DBN, we adjusted different parameters to achieve the best performance when solving different emotions. Both gender‐dependent and gender‐independent experiments were conducted on the Chinese Academy of Sciences emotional speech database. The mean accuracy of SVM is 84.54%, and the mean accuracy of DBN is 94.6%. The experiments show that the DBN‐based approach has good potential for practical usage, and suitable feature fusions will further improve the performance of speech emotion recognition.

Published: September 2023

AbstractIntel includes in its recent processors a powerful set of instructions capable of processing 512‐bit registers with a single instruction (AVX‐512). Some of these instructions have no equivalent in earlier instruction sets. We leverage these instructions to efficiently transcode strings between the most common formats: UTF‐8 and UTF‐16. With our novel algorithms, we are often twice as fast as the previous best solutions. For example, we transcode Chinese text from UTF‐8 to UTF‐16 at more than 5 GiB using fewer than 2 CPU instructions per character. To ensure reproducibility, we make our software freely available as an open‐source library. Our library is part of the popular Node.js JavaScript runtime.
