Authors: Arslan Ümüt , Okur Sinan , Smock Jordan Sara
Published: June 2023

This study aims to adapt Solution Building Inventory (SBI) to Turkish and examine its psychometric properties. The study group consisted of 278 individuals (195 females and 83 males), whose age range was between 18 and 23 years old. Solution Building Inventory, Dispositional Hope Scale, and Positive and Negative Affect Scale were used as measurements. The results of the exploratory factor analysis showed the suitability of the data for factor analysis and revealed a two-factor structure explaining 49.38% of the total variance. Confirmatory factor analysis findings showed that the model had a good fit in the 11-item and two-dimensional structure of the scale. Besides, the correlation coefficients of the relationship between the SBI and other scales were expectedly provided equivalent and convergent validity. In reliability analyzes, the Cronbach alpha internal consistency coefficient of the scale was found to be .85 for the scale in general, while it was calculated as .78 for the supporting solutions sub-dimension and .85 for the creating solutions sub-dimension. As a result, SBI is a measurement tool with proven validity and reliability in Turkish.

Language Analysis in Solution-Focused Therapy Training: Comparing Trainees With Their Trainer
Authors: Zamanillo Alberto , Rodríguez-Morejón Alberto
Published: June 2023

When the question of expertise arises in the field of psychotherapy, many authors question whether it is achievable or not (Hill et al., 2017; Shanteau, 1992; Shanteau & Weiss, 2014; Tracey et al., 2014), and some ask how to characterize it (Levitt & Piazza-Bonin, 2016; Norcross & Karpiak, 2017). Ultimately, we need to know what specific actions are performed by an expert psychotherapist (Hill et al., 2017); the importance of research on expert psychotherapists does not reside solely in establishing the effect that experience has on clinical performance. Experts are also models who teach and supervise new psychotherapists (Hill et al., 2015; Hill & Knox, 2013). Therefore, we need to look more closely at what psychotherapists do

A male pilot whale, Globicephala sp., was reported as a live stranding on 1st March 2012 at Hazelbeach, near Neyland, Pembrokeshire. It was euthanased and its skull was recovered during an onsite necropsy. Examination of the skull and contemporary photographs of the stranded animal confirm that this is the first record of short-finned pilot whale, Globicephala macrorhynchus, in  Britain.
First records of harbour seals (Phoca vitulina vitulina) breeding in SW Britain.
Authors: Westcott Stephen
Published: June 2023

Harbour seals (Phoca vitulina vitulina) are found around the coast of Scotland (including the Hebridean and Northern Islands), Northern Ireland and parts of England but only occasionally at sites in Wales and SW England (SW Britain). One site in SW Britain is the Dart estuary in Devon, where sightings have been recorded since 2006. This paper documents the birth of two harbour seal pups in 2019 and two in 2020 on the Dart estuary with all surviving to weaning. The local assembly of adult harbour seals consisted of two males and two females in both years. These are thought to be the first records of this kind in the region.
Annual fluctuations in harvest mouse (Micromys minutus) nest densities in southern England.
Authors: Lloyd Amanda , Kirk Steven
Published: June 2023

Aerial nest surveys are the principal method of monitoring the distribution and habitat preferences of harvest mice (Micromys minutus), but monitoring has rarely been undertaken for more than three years at any site. Although nest surveys have inherent errors, they remain the most easily accessible and cheapest method. The aim of this study was to count the number of nests found in consecutive years at two sites in southern England. We found that the harvest mouse nest densities fluctuated over time. This supports other studies that indicate harvest mice populations undergo major fluctuations from year to year. Although the drivers of this annual variation in nest numbers have not yet been identified, surveying for harvest mice using aerial nest counts in just one year could underestimate their likely presence at that site.

Published: June 2023

Analysis of the teaching and learning process needs to be done as feedback on the understanding of the material for students. One of the obstacles faced by schools is that there is no method of how this feedback can be done so that student achievement is uneven. Student achievement in subjects can be seen from the results of the scores on the report cards obtained by students after taking the final semester exam. Due to the uneven achievement of students, it is necessary to make a method so that feedback analysis can be carried out on the level of student understanding of the subject. Is data mining with clustering techniques using the K-Medoids algorithm. With this algorithm, students' understanding of subjects with high potential can be grouped with high brightness average results

Published: June 2023

Production system at UD. Mie Akwang is a home industry that provides raw materials for noodle production. Uncertain consumer demand and supplies that are not in accordance with demand make it difficult for this industry to determine the amount of production that will be produced. Previously, this home industry did not have a valid rule to determine the amount of production that must be achieved. Therefore, a decision support system was developed using the Fuzzy Tsukamoto method. This method is the right method in making decisions that use several criteria to produce decisions on the amount of production. In this study, the data used is in the form of data on the amount of production in April 2021. From the calculation process that has been carried out, it can be concluded that if the demand is 28,950 portions and the supply is 30,000 portions, the total production produced is 31,207 portions. The results of these calculations are implemented in the form of a production system and the results obtained are the same, namely 31,207 portions.
DEVELOPMENT OF HYBRID ENCRYPTION METHOD USING AFFINE CIPHER, VIGENERE CIPHER, AND ELGAMAL ALGORITHM TO SECURE TEXT MESSAGES IN DATA COMMUNICATION SYSTEM

Published: June 2023

With the development of technological advances in this day and age, it definitely requires a security system on messages and data. The way to maintain the security of data, messages or information requires a branch of science in its application, one of which is the algorithm or cryptography method. In its application, it requires more than one stage of the security process, because data security can be done by combining methods in its security techniques. This research aims to develop encryption methods using Affine Cipher, Vigenere Cipher, and ElGamal Algorithm to secure text messages. Affine cipher, Vigenere cipher and ElGamal are cryptography that can encrypt and decrypt text messages. Encryption is changing the message or plaintext into an unreadable message or ciphertext, on the other hand, decryption changes the ciphertext or message that initially cannot be read into a message that can be read or plaintext back in its original form. The result of this research is the development stage by doing three encryption and decryption processes. For the first encryption process using Affine Chiper which produces the initial ciphertext, then re-encrypted using Vigenere Cipher, then the previous encryption results are carried out ElGamal encryption which produces the final ciphertext. Conversely, the decryption process is first on ElGamal, then Vigenere Cipher, and finally Affine Cipher whose decryption results in plaintext back in the form of the initial text message. So that by developing and combining three algorithm methods can increase the security of information and text messages.
A Review: Design and Build Damage Detection Equipment on Sensors and Power Supply Automatic Rain Gauge (ARG) With Long Short Term Memory Integrated
Authors: Sinambela Marzuki
Published: June 2023

The Meteorology, Climatology, and Geophysics Agency (BMKG) technicians have successfully developed automatic rain measuring devices. This tool is called Automatic Rain Gauge - BMKG (ARG-BMKG). The existence of this instrument can replace conventional rain measuring observation systems or public rain stations in Indonesia. ARG – BMKG consists of a tipping bucket sensor, solar panels, GPRS modem, dry battery, and data logger. This repeated operation causes sensor measurement errors due to damage to the sensor due to the sensor voltage supply not meeting specifications, resulting in inaccurate data sent. Predicting sensor damage can be done with predictive maintenance.  The results of field tests in previous studies showed that the system could operate properly where the device could measure the voltage of each sensor and send data to the database A sensor damage prediction model was designed and implemented using long-sort term memory (LSTM) by generating root mean square error (rmse).  The system can provide damage prediction information on the sensor, and the power supply is displayed through the website properly

Published: June 2023

The use of image media information has several weaknesses, one of which is the ease with which it can be manipulated by irresponsible people. Efforts made in increasing the security of this image is cryptography, namely the science and art of maintaining the security and confidentiality of images. Cryptography is used so that the confidentiality of the image can be maintained, so that it is not known by others. In general, there are 2 (two) techniques for carrying out cryptographic processes, namely encryption and decryption. In this study, the encryption process was first carried out using the Affine Cipher algorithm and then continued with the Merkle Hellman algorithm, while the decryption was carried out first by Merkle Hellman and then decrypted again with the Affine Cipher. The results of this study indicate that applying the Affine Cipher and Merkle Hellman algorithms can secure images. At the end of this system is an image that is in the form of blur so that it is not known and not understood by others. That way people who are not entitled cannot understand from the image.

Published: June 2023

The HIV/AIDS epidemic in Sweden accelerated the hybridisation of welfare, as volunteer organisations underwent rapid processes of professionalization and assumed growing responsibilities for the distribution of welfare services. A sense of urgency prompted by terrifying horror scenarios spread in the media and helped motivate politicians and fund-giving agencies to channel large amounts of money into volunteer organisations like RFSL (the National Union for Sexual Equality), RFSU (the Swedish Association for Sexuality Education) and Noaks Ark, as well as to the various self-help groups that emerged for HIV-positive men who had sex with men, drug users, haemophiliacs, and, to a lesser degree, sex workers. The article focus on how these volunteer organisations – old and new – interacted with the state and the public health sector, how they interacted – and came into conflict – with each other, and how the membership-oriented activities changed over time due to professionalisation and to the introduction of anti-retroviral drugs in 1996.

I min diskussion af forfatternes nuancerende perspektiv på, hvordan higher order thinking manifesterer sig i undervisningen, forskyder jeg fokus fra elevers tænkning til elevers gøren. I den forbindelse foreslår jeg, at man, som alternativ eller supplement til evalueringen af elevers tænkning, kan betragte potentialet for udviklingen heraf i lyset af elevernes måder at engagere sig og deltage mere eller mindre bevidst reflekteret i den dialog og samtale, som finder sted i undervisningen.
Introspection of Raimundus Lullus
Authors: Akimov Oleg Yur'evich
Published: June 2023

The spiritual quest of Raymond Lull is of interest to modern philosophical discourse as occupying an intermediate position between the Middle Ages and the Renaissance and thus combining the features of these two eras in the history of the development of human thought. They are connected with the Middle Ages by theocentrism and traditionalism, and with the Renaissance by emphasizing the peculiar polyphony of the world, the predominance of plurality over unity, given in the autonomous dialogic space of the human personality as a gradual immanentization of the presence of a transcendent deity, associated with the acceptance by man of the external world as the only possible one. This immanentization is carried out by Luli in the symbol of Love as the Unity of the Loving and the Beloved, explicating the thinker's introspection. The novelty of the work lies in the application of the teachings of A.F. Losev about the interpretive symbol, which made it possible to consider them as a special form of explication of the personality as its transcendence and simultaneous immanence, being a special form of introspection, which correlates with Lull's teaching about Love as a fluctuation in which the Beloved descends, and the Lover ascends. This contributes to the actualization of Lull's spiritual quest as an integrity, a unique eidos, in which each of the separate features of Raymond Lull's spiritual quest is realized in a special way, reflecting the intermediate position occupied by the thinker between the worlds of Antiquity and the Middle Ages. The proposed model of mutual positing of the "components" of Lull's teaching allows us to show one of the possibilities for the interaction of the thinker's logical system (understanding the force, its bearer and passively perceiving its beginning) and his theologically oriented personal spiritual quest as a special kind of dynamics in which the leading role is assigned to introspection as a personal intentions, a kind of mythological sub-foundation of the actual logical dimension of the thinker's teachings.
A billion years arms-race between viruses, virophages, and eukaryotes
Authors: Barreat Jose Gabriel Nino , Katzourakis Aris
Published: June 2023

Bamfordviruses are arguably the most diverse group of viruses infecting eukaryotes. They include the Nucleocytoplasmic Large DNA viruses (NCLDVs), virophages, adenoviruses, Mavericks and Polinton-like viruses. Two main hypotheses for their origins have been proposed: the ‘nuclear-escape’ and ‘virophage-first’ hypotheses. The nuclear-escape hypothesis proposes an endogenous, Maverick-like ancestor which escaped from the nucleus and gave rise to adenoviruses and NCLDVs. In contrast, the virophage-first hypothesis proposes that NCLDVs coevolved with protovirophages; Mavericks then evolved from virophages that became endogenous, with adenoviruses escaping from the nucleus at a later stage. Here, we test the predictions made by both models and consider alternative evolutionary scenarios. We use a data set of the four core virion proteins sampled across the diversity of the lineage, together with Bayesian and maximum-likelihood hypothesis-testing methods, and estimate rooted phylogenies. We find strong evidence that adenoviruses and NCLDVs are not sister groups, and that Mavericks and Mavirus acquired the rve-integrase independently. We also found strong support for a monophyletic group of virophages (family Lavidaviridae) and a most likely root placed between virophages and the other lineages. Our observations support alternatives to the nuclear-escape scenario and a billion years evolutionary arms-race between virophages and NCLDVs.

Published: June 2023

This study investigates the goal/habit imbalance theory of compulsion in obsessive-compulsive disorder (OCD), which postulates enhanced habit formation, increased automaticity, and impaired goal/habit arbitration. It directly tests these hypotheses using newly developed behavioral tasks. First, OCD patients and healthy participants were trained daily for a month using a smartphone app to perform chunked action sequences. Despite similar procedural learning and attainment of habitual performance (measured by an objective automaticity criterion) by both groups, OCD patients self-reported higher subjective habitual tendencies via a recently developed questionnaire. Subsequently, in a re-evaluation task assessing choices between established automatic and novel goal-directed actions, both groups were sensitive to re-evaluation based on monetary feedback. However, OCD patients, especially those with higher compulsive symptoms and habitual tendencies, showed a clear preference for trained/habitual sequences when choices were based on physical effort, possibly due to their higher attributed intrinsic value. These patients also used the habit-training app more extensively and reported symptom relief post-study. The tendency to attribute higher intrinsic value to familiar actions may be a potential mechanism leading to compulsions and an important addition to the goal/habit imbalance hypothesis in OCD. We also highlight the potential of smartphone app training as a habit reversal therapeutic tool.

Published: June 2023

Malfunction of the CFTR protein results in cystic fibrosis, one of the most common hereditary diseases. CFTR functions as an anion channel, the gating of which is controlled by long-range allosteric communications. Allostery also has direct bearings on CF treatment: the most effective CFTR drugs modulate its activity allosterically. Herein, we integrated Gaussian network model, transfer entropy, and anisotropic normal mode-Langevin dynamics and investigated the allosteric communications network of CFTR. The results are in remarkable agreement with experimental observations and mutational analysis and provide extensive novel insight. We identified residues that serve as pivotal allosteric sources and transducers, many of which correspond to disease-causing mutations. We find that in the ATP-free form, dynamic fluctuations of the residues that comprise the ATP-binding sites facilitate the initial binding of the nucleotide. Subsequent binding of ATP then brings to the fore and focuses on dynamic fluctuations that were present in a latent and diffuse form in the absence of ATP. We demonstrate that drugs that potentiate CFTR’s conductance do so not by directly acting on the gating residues, but rather by mimicking the allosteric signal sent by the ATP-binding sites. We have also uncovered a previously undiscovered allosteric ‘hotspot’ located proximal to the docking site of the phosphorylated regulatory (R) domain, thereby establishing a molecular foundation for its phosphorylation-dependent excitatory role. This study unveils the molecular underpinnings of allosteric connectivity within CFTR and highlights a novel allosteric ‘hotspot’ that could serve as a promising target for the development of novel therapeutic interventions.

Malfunction of the CFTR protein results in cystic fibrosis, one of the most common hereditary diseases. CFTR functions as an anion channel, the gating of which is controlled by long-range allosteric communications. Allostery also has direct bearings on CF treatment: CFTR drugs bind at the periphery of the protein yet affect the gating residues that lie at the center of it. Herein, we combined two computational approaches; Anisotropic Normal Mode-Langevin dynamics (ANM-LD) and Transfer Entropy (TE) and investigated the allosteric communications network of CFTR. The results are in excellent agreement with experimental observations and provide extensive novel insight. We identified residues that serve as pivotal allosteric sources and transducers, many of which correspond to disease causing mutations. We observe that the degenerate and catalytic ATP sites asymmetrically contribute to the allosteric communication, and that the catalytic site provides the greater allosteric input. We demonstrate that drugs that potentiate CFTR’s conductance do so not by directly acting on the gating residues, but rather by mimicking the allosteric signal sent by the ATP binding sites. We identify a hitherto unknown allosteric hotspot near the docking site of the phosphorylated R domain, providing a molecular basis for its phosphorylation dependent excitatory role. This study uncovers the molecular basis of allosteric connectivity in CFTR and reveals a novel allosteric hotspot that can serve as a target for the development of novel therapeutics.
Interspecific variation and phylogenetic relationship between mangrove and non-mangrove species of a same family (Meliaceae)—insights from comparative analysis of complete chloroplast genome
Authors: Tan Fengxiao , Li Weixi , Feng Hui , Huang Yelin , Banerjee Achyut Kumar
Published: June 2023

The mahogany family, Meliaceae, contains 58 genera with only one mangrove genus: Xylocarpus. Two of the three species of the genus Xylocarpus are true mangroves (X. granatum and X. moluccensis), and one is a non-mangrove (X. rumphii). In order to resolve the phylogenetic relationship between the mangrove and non-mangrove species, we sequenced chloroplast genomes of these Xylocarpus species along with two non-mangrove species of the Meliaceae family (Carapa guianensis and Swietenia macrophylla) and compared the genome features and variations across the five species.

The five Meliaceae species shared 130 genes (85 protein-coding genes, 37 tRNA, and eight rRNA) with identical direction and order, with a few variations in genes and intergenic spacers. The repetitive sequences identified in the rpl22 gene region only occurred in Xylocarpus, while the repetitive sequences in accD were found in X. moluccensis and X. rumphii. The TrnH-GUG and rpl32 gene regions and four non-coding gene regions showed high variabilities between X. granatum and the two non-mangrove species (S. macrophylla and C. guianensis). In addition, among the Xylocarpus species, only two genes (accD and clpP) showed positive selection. Carapa guianensis and S. macrophylla owned unique RNA editing sites. The above genes played an important role in acclimation to different stress factors like heat, low temperature, high UV light, and high salinity. Phylogenetic analysis with 22 species in the order Sapindales supported previous studies, which revealed that the non-mangrove species X. rumphii is closer to X. moluccensis than X. granatum. Overall, our results provided important insights into the variation of genetic structure and adaptation mechanism at interspecific (three Xylocarpus species) and intergeneric (mangrove and non-mangrove genera) levels.
Saccharibacteria (TM7), but not other bacterial taxa, are associated with childhood caries regardless of age in a South China population

Published: June 2023

Background

Human microbiome dysbiosis is related to various human diseases, and identifying robust and consistent biomarkers that apply in different populations is a key challenge. This challenge arises when identifying key microbial markers of childhood caries.

Methods

We analyzed unstimulated saliva and supragingival plaque samples from children of different ages and sexes, performed 16S rRNA gene sequencing, and sought to identify whether consistent markers exist among subpopulations by using a multivariate linear regression model.

Results

We found that Acinetobacter and Clostridiales bacterial taxa were associated with caries in plaque and saliva, respectively, while Firmicutes and Clostridia were found in plaque isolated from children of different ages in preschool and school. These identified bacterial markers largely differ between different populations, leaving only Saccharibacteria as a significant caries-associated phylum in children. Saccharibacteria is a newly identified phylum, and our taxonomic assignment database could not be used to identify its specific genus.

Conclusion

Our data indicated that, in a South China population, oral microbial signatures for dental caries show age and sex differences, but Saccharibacteria might be a consistent signal and worth further investigation, considering the lack of research on this microbe.

Published: June 2023

The present study was conducted to identify the association of non-destructive rapid estimation of stalk volume by calculation method with water displacement method and to predict the single cane weight by stalk volume. The stalk volume by water displacement method (SVWM) and stalk volume by calculation method (SVCM) were compared for the efficacy of stalk weight determination in sugarcane clones. Results from both methods were similar and a highly significant relationship was found between the two methods (r2 = 0.9092, P < 0.0001). Both protocols provide consistent stalk volume measurements; however, the stalk volume calculation method is preferred for its quick evaluation of a large number of stalks in a rapid way besides its non-destructive nature. The calculation method saved more than 70 seconds for each sample. The stalk weight has shown a significant correlation of r=0.71***, 0.83***, 0.94***, 0.99*** with SH, CD, SVCM and SVWM respectively, while the stalk density (SD) was observed with a negative correlation (r=-0.27ns) with stalk weight. The stalk volume-based predicted stalk weight estimation was observed with high degree of correlation (>0.88***) with the original single cane weight by both the studied methods, thus, measurements of stalk volume based on calculation method which provide simple, rapid, non-destructive field phenotyping of single cane weight in sugarcane crop may be recommended for the sugarcane research.

Beekeeping, otherwise known as apiculture is a lucrative business providing supplementary or major income to the people in rural areas. Honey has certain health benefits, with its nutritional composition closely similar to fruits and is a natural sweetener. Honeybees are also a good pollinator and gives valued products such as beewax, propolis, bee venom, etc. However, for commercial beekeeping, selection of bee species is very important and for yearly flow of honey, a beekeeper should know the flora preferred by the bees for every seasons. The present study revealed that, out of the total 161 plant species identified, which is visited by the honeybees (Apis cerana and Apis mellifera) for nectar and pollen, maximum plant species belong to the horticultural crops (33%) followed by the wild plants and forest trees (29%); and ornamental plants and avenue trees (28%). The least (10%) was recorded in agronomic crops.
Analysis of the Effect of Deep-learning Super-resolution for Fragments Detection Performance Enhancement
Authors: Lee Yuseok
Published: June 2023

The Arena Fragmentation Test(AFT) is designed to analyze warhead performance by measuring fragmentation data. In order to evaluate the results of the AFT, a set of AFT images are captured by high-speed cameras. To detect objects in the AFT image set, ResNet-50 based Faster R-CNN is used as a detection model. However, because of the low resolution of the AFT image set, a detection model has shown low performance. To enhance the performance of the detection model, Super-resolution(SR) methods are used to increase the AFT image set resolution. To this end, The Bicubic method and three SR models: ZSSR, EDSR, and SwinIR are used. The use of SR images results in an increase in the performance of the detection model. While the increase in the number of pixels representing a fragment flame in the AFT images improves the Recall performance of the detection model, the number of pixels representing noise also increases, leading to a slight decreases in Precision performance. Consequently, the F1 score is increased by up to 9 %, demonstrating the effectiveness of SR in enhancing the performance of the detection model.
Development of ESAD with Flight Environment Sensing Function and Sled Test Method for Function Verification
Authors: Jo Hanseong
Published: June 2023

Recently electronic safety and arming device(ESAD) has attracted increasing attention due to its design flexibility. However, ESAD can be armed unintentionally due to a malfunction of an external device or interface. Thus ESAD needs an internally generated arming signal independent from the external device. In this paper, a new sensor-hybrid ESAD(SHESAD) with a flight environment sensing function for generating arming signal internally is proposed and a sled test based method is also suggested for evaluating its functions. Through the test results, the operability of the flight environment sensing function was confirmed. Also, it is shown that the proposed test method is suitable for verification of ESAD with the flight environment sensing function.

Importance

Questions remain concerning treatment efficacy for the common condition of benign paroxysmal positional vertigo (BPPV).

Objective

To compare the effectiveness of the Semont-plus maneuver (SM-plus) and the Epley maneuver (EM) for treatment of posterior canal benign paroxysmal positional vertigo (pcBPPV) canalolithiasis.

Design, Setting, and Participants

This prospective randomized clinical trial was performed at 3 national referral centers (in Munich, Germany; Siena, Italy; and Bruges, Belgium) over 2 years, with a follow-up to 4 weeks after the initial examination. Recruitment took place from June 1, 2020, until March 10, 2022. Patients were selected randomly during routine outpatient care after being referred to 1 of the 3 centers. Two hundred fifty-three patients were assessed for eligibility. After consideration of the exclusion criteria as well as informed consent, 56 patients were excluded and 2 declined to participate, with 195 participants included in the final analysis. The analysis was prespecified and per-protocol.

Interventions

After being randomized to the SM-plus or the EM group, patients received 1 initial maneuver from a physician, then subsequently performed self-maneuvers at home 3 times in the morning, 3 times at noon, and 3 times in the evening.

Main Outcome and Measures

Patients had to document whether they could provoke positional vertigo every morning. The primary end point was the number of days until no positional vertigo could be induced on 3 consecutive mornings. The secondary end point was the effect of the single maneuver performed by the physician.

Results

Of the 195 participants included in the analysis, the mean (SD) age was 62.6 (13.9) years, and 125 (64.1%) were women. The mean (SD) time until no positional vertigo attacks could be induced in the SM-plus group was 2.0 (1.6) days (median, 1 [range, 1-8] day; 95% CI, 1.64-2.28 days); in the EM group, 3.3 (3.6) days (median, 2 [range, 1-20] days; 95% CI, 2.62-4.06 days) (P = .01; α = .05, 2-tailed Mann-Whitney test). For the secondary end point (effect of a single maneuver), no significant difference was detected (67 of 98 [68.4%] vs 61 of 97 [62.9%]; P = .42; α = .05). No serious adverse event was detected with both maneuvers. Nineteen patients (19.6%) in the EM group and 24 (24.5%) in the SM-plus group experienced relevant nausea.

Conclusions and Relevance

The SM-plus self-maneuver is superior to the EM self-maneuver in terms of the number of days until recovery in pcBPPV.

Stroke is a serious neurological disease and a significant contributor to disability worldwide. Traditional in‐hospital imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) remain the standard modalities for diagnosing stroke. The development of prehospital stroke detection devices may facilitate earlier diagnosis, initiation of stroke care, and ultimately better patient outcomes. In this review, the authors summarize the features of eight stroke detection devices using noninvasive brain scanning technology. The review summarizes the features of stroke detection devices including portable CT, MRI, transcranial Doppler ultrasound , microwave tomographic imaging, electroencephalography, near‐infrared spectroscopy, volumetric impedance phaseshift spectroscopy, and cranial accelerometry. The technologies utilized, the indications for application, the environments indicated for application, the physical features of the eight stroke detection devices, and current commercial products are discussed. As technology advances, multiple portable stroke detection instruments exhibit the promising potential to expedite the diagnosis of stroke and enhance the time taken for treatment, ultimately aiding in prehospital stroke triage.

Published: June 2023

In the process of grid connection of irregular output micro‐grid systems, it is of great research significance to make micro‐grid scheduling operate more effectively and economically. To minimize the environmental and total operating costs of the micro‐grid intelligent scheduling system during grid connection, this study proposes a micro‐grid intelligent scheduling model based on an optimized particle swarm optimization algorithm. The optimized particle swarm algorithm mainly improves the problem of the particle swarm algorithm being prone to local optima, making it reduce the possibility of local convergence. Comparative tests were conducted on the improved IPSO algorithm, and the results showed that the non‐dominated solution concentration pollution emissions obtained by the improved IPSO algorithm were at least 18326 Ib, which was lower than the comparison algorithm. In the empirical analysis of the intelligent scheduling model based on the improved IPSO algorithm, the convergence and satisfaction of the model were 0.0054 and 0.922, respectively, which were superior to the comparison algorithm. The above results indicate that the intelligent scheduling model for micro‐grid based on the improved IPSO algorithm has good economy and stability. Compared with traditional energy dispatch methods, this energy dispatch mode has higher economic benefits and is of great significance for promoting the development of micro‐grid.

In recent years, an increasing number of 2D van der Waals (vdW) materials are theory‐predicted or laboratory‐validated to possess in‐plane (IP) and/or out‐of‐plane (OOP) spontaneous ferroelectric polarization. Due to their dangling‐bond‐free surfaces, interlayer charge coupling, robust polarization, tunable energy band structures, and compatibility with silicon‐based technologies, vdW ferroelectric materials exhibit great promise in ferroelectric memories, neuromorphic computing, nanogenerators, photovoltaic devices, spintronic devices, and so on. Here, the very recent advances in the field of vdW ferroelectrics (FEs) are reviewed. First, theories of ferroelectricity are briefly discussed. Then, a comprehensive summary of the non‐stacking vdW ferroelectric materials is provided based on their crystal structures and the emerging sliding ferroelectrics. In addition, their potential applications in various branches/frontier fields are enumerated, with a focus on artificial intelligence. Finally, the challenges and development prospects of vdW ferroelectrics are discussed.

Pure organic circularly polarized room‐temperature phosphorescence (CPRTP) materials show significant promise for applications in advanced anti‐counterfeiting, biological imaging, and so on. However, it remains challenging to prepare CPRTP materials with a high phosphorescence luminescence dissymmetry factor (glum). This article provides a simple and efficient method to prepare pure organic CPRTP materials with high phosphorescence glum from cholesteric liquid crystals by incorporation of achiral phosphorescent chromophore dibenzofuran into chiral cholesterol mesogen via a flexible spacer. The findings show that the synthetic compound Chol‐C6‐DF can form cholesteric liquid crystals and can effectively amplify the glum value through selective reflection. The Chol‐C6‐DF film can produce yellow CPRTP when excited by a dibenzofuran chromophore. The glum value, the lifetime, and the quantum yield of the yellow CPRTP produced by dibenzofuran under the excitation of 380 nm light are −0.19, 567.7 ms, and 3.2%, respectively. Even more interesting is that the chiral cholesterol also exhibits RTP and clustering‐triggered emission characteristics. The glum value and the lifetime of red CPRTP produced by cholesterol under the excitation of 420 nm light are ‐0.11 and 1.11 s. Under excitation of 410, 430, and 470 nm light, the phosphorescent quantum yields are 19.0%, 20.2%, and 19.1%, respectively.

Developing plasmonic biosensors that are low‐cost, portable, and relatively simple to operate remains challenging. Herein, a novel metasurface plasmon‐etch immunosensor is described, namely a nanozyme‐linked immunosorbent surface plasmon resonance biosensor, for the ultrasensitive and specific detection of cancer biomarkers. Gold‐silver composite nano cup array metasurface plasmon resonance chip and artificial nanozyme‐labeled antibody are used in two‐way sandwich analyte detection. Changes in the biosensor's absorption spectrum are measured before and after chip surface etching, which can be applied to immunoassays without requiring separation or amplification. The device achieved a limit of alpha‐fetoprotein (AFP) detection < 21.74 fM, three orders of magnitude lower than that of commercial enzyme‐linked immunosorbent assay kits. Additionally, carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125) are used for quantitative detection to verify the universality of the platform. More importantly, the accuracy of the platform is verified using 60 clinical samples; compared with the hospital results, the three biomarkers achieve high sensitivity (CEA: 95.7%; CA125: 90.9%; AFP: 86.7%) and specificity (CEA: 97.3%; CA125: 93.9%; AFP: 97.8%). Due to its rapidity, ease of use, and high throughput, the platform has the potential for high‐throughput rapid detection to facilitate cancer screening or early diagnostic testing in biosensing.

Zn‐N‐C possesses the intrinsic inertia for Fenton‐like reaction and can retain robust durability in harsh circumstance, but it is often neglected in oxygen reduction reaction (ORR) because of its poor catalytic activity. Zn is of fully filled 3d104s2 configuration and is prone to evaporation, making it difficult to regulate the electronic and geometric structure of Zn center. Here, guided by theoretical calculations, five‐fold coordinated single‐atom Zn sites with four in‐plane N ligands is constructed and one axial O ligand (Zn‐N4‐O) by ionic liquid‐assisted molten salt template method. Additional axial O not only triggers a geometry transformation from the planar structure of Zn‐N4 to the non‐planar structure of Zn‐N4‐O, but also induces the electron transfer from Zn center to neighboring atoms and lower the d‐band center of Zn atom, which weakens the adsorption strength of *OH and decreases the energy barrier of rate determining step of ORR. Consequently, the Zn‐N4‐O sites exhibit improved ORR activity and excellent methanol tolerance with long‐term durability. The Zn‐air battery assembled by Zn‐N4‐O presents a maximum power density of 182 mW cm−2 and can operate continuously for over 160 h. This work provides new insights into the design of Zn‐based single atom catalysts through axial coordination engineering.

The advancement of non‐fullerene acceptors with crescent‐shaped geometry has led to the need for polymer donor improvements. Additionally, there is potential to enhance the photovoltaic parameters in high‐efficiency organic solar cells (OSCs). The random copolymerization method is a straightforward and effective strategy to further optimize photoactive morphology and enhance device performance. However, finding a suitable third component in terpolymers remains a crucial challenge. In this study, a series of terpolymer donors (PTF3, PTF5, PTF10, PTF20, and PTF50) is synthesized by introducing varying amounts of the trifluoromethyl‐substituted unit (CF3) into the PM6 polymer backbone. Even subtle changes in the CF3 content can significantly enhance all the photovoltaic parameters due to the optimized energy levels, molecular aggregation/miscibility, and bulk‐heterojunction morphology of the photoactive materials. Thus, the best binary OSC based on the PTF5:Y6‐BO achieves an outstanding power conversion efficiency (PCE) of 18.2% in the unit cell and a PCE of 11.6% in the sub‐module device (aperture size: 54.45 cm2), when using halogen‐free solvent o‐xylene. This work showcases the remarkable potential of the easily accessible CF3 unit as a key constituent in the construction of terpolymer donors in high‐performance OSCs.

Published: June 2023

A multimodal deep‐learning (MDL) framework is presented for predicting physical properties of a ten‐dimensional acrylic polymer composite material by merging physical attributes and chemical data. The MDL model comprises four modules, including three generative deep‐learning models for material structure characterization and a fourth model for property prediction. The approach handles an 18‐dimensional complexity, with ten compositional inputs and eight property outputs, successfully predicting 913 680 property data points across 114 210 composition conditions. This level of complexity is unprecedented in computational materials science, particularly for materials with undefined structures. A framework is proposed to analyze the high‐dimensional information space for inverse material design, demonstrating flexibility and adaptability to various materials and scales, provided sufficient data are available. This study advances future research on different materials and the development of more sophisticated models, drawing the authors closer to the ultimate goal of predicting all properties of all materials.
