Published: May 2023

Abstract
Inertial migration of micro- and nanoparticles flowing through microchannels is commonly used for particle separation, sorting, and focusing on many lab-on-a-chip devices. Computer simulations of inertial migration of nanoparticles by mesoscale simulation methods, such as Dissipative Particle Dynamics (DPD) would be helpful to future experimental development of these lab-on-a-chip devices. However, the conventional DPD approach has a low Schmidt number and its ability to model inertial migration is questioned. In this work, we examine the ability of DPD simulations to investigate the inertial migration of rigid nanoparticles flowing through a slit channel. By varying the exponent and cutoff distance in the weight function of the random and dissipative forces, DPD models with Schmidt number varying between 1 and 370 were examined. We show that solvent penetration into nanoparticles and solvent-induced attraction between nanoparticles can be controlled by choosing appropriate interaction coefficients of the DPD conservative force and that these properties are not influenced by the Schmidt number of the DPD model. On the other hand, hydrodynamic properties and transport behaviour of rigid nanoparticles are influenced by the Schmidt number. With the conventional DPD model, nanoparticles tend to be evenly distributed across the channel and do not remain in steady-state positions during flow. At high Schmidt numbers, the particles migrate to long-lasting steady-state positions located between the channel center and walls, in agreement with known experimental observations. We conclude that to properly simulate inertial migration, modifications to the conventional DPD model that yield a high Schmidt number are required.

Abstract
The nanosecond (ns) pulsed nitrogen dielectric barrier discharge (DBD) is employed to enhance the hydrophilicity of polypropylene (PP) surface and improve its application effect. The discharge characteristics of the ns pulsed nitrogen DBD with different pulse rise times (from 50 to 500 ns) are investigated by electrical and optical diagnostic methods and the discharge uniformity is quantitatively analyzed by image processing method. To characterize the surface hydrophilicity, the water contact angle (WCA) is measured, and the physical morphology and chemical composition of PP before and after modification are analyzed to explore the effect of plasma on PP surface. It is found that with increasing pulse rise time from 50 to 500 ns, DBD uniformity becomes worse, energy efficiency decreases from 20% to 10.8%, and electron density decrease from 6.6 × 1011 to 5.5 × 1011 cm−3. The tendency of electron temperature is characterized with the intensity ratio of N2/N+
2 emission spectrum, which decreases from 17.4 to 15.9 indicating the decreasing of T
e with increasing pulse rise time from 50 to 500 ns. The PP surface treated with 50 ns pulse rise time DBD has a lower WCA (∼47°), while the WCA of PP treated with 100 to 500 ns pulse rise time DBD expands gradually (∼50°‒57°). According to the study of the fixed-point WCA values, the DBD-treated PP surface has superior uniformity under 50 ns pulse rise time (3° variation) than under 300 ns pulse rise time (8° variation). After DBD treatment, the increased surface roughness from 2.0 to 9.8 nm and hydrophilic oxygen-containing groups on the surface, i.e. hydroxyl (−OH) and carbonyl (C=O) have played the significant role to improve the sample’s surface hydrophilicity. The short pulse voltage rise time enhances the reduced electric field strength (E/n) in the discharge space and improves the discharge uniformity, which makes relatively sufficient physical and chemical reactions have taken place on the PP surface, resulting in better treatment uniformity.

Abstract
Indium gallium tin oxide (IGTO) thin films have the potential for high mobility and low-temperature processing, which makes them suitable for applications such as display backplanes and high-voltage switching devices. However, very few studies have investigated the plasma-etching characteristics of IGTO and changes in its properties after etching. In this study, the etching characteristics of IGTO were investigated using Cl2/Ar plasma, and changes in surface properties were analyzed. Results showed that the etch rate increased with an increase in the proportion of Cl2, with the highest etch rate observed at 69 nm min−1 in pure Cl2 plasma with a gas flow rate of 100 sccm. Furthermore, increased radio-frequency power caused a rise in the etch rate, while a process pressure of 15 mTorr was optimal. The primary etching mechanism for IGTO thin films under Cl2 plasma was a chemical reaction, and an increased work function indicated the occurrence of defects on the surface. In addition, the etching process reduced the surface roughness of Cl2-containing plasma, whereas the etching process in pure Ar plasma increased surface roughness. This study contributes to a better understanding of the plasma-etching characteristics of IGTO and changes in its properties after etching, providing valuable insights for IGTO-based applications.
Reliable p-type organic permeable base transistors—the missing component for integrated circuits

Published: May 2023

Abstract
Due to their nm-range channel length, vertical organic transistors are gaining scientific interest to overcome the frequency limitations of lateral organic transistor. Especially, vertical organic permeable base transistors (OPBTs) with a structure resembling a vacuum-tube-triode stand out due to their excellent electrical performance. Recently, n-type OPBTs have been demonstrated with excellent performance and great potential to be applied in high-frequency logic circuits, display driving circuits, and light-emitting devices. However, achieving adequate p-type OPBTs to catch up with the performance of n-type devices is still challenging. Here, we report on the peculiar finding that the extended exposure of p-type OPBTs to ambient air during the fabrication has a positive effect on the electrical performance and tremendously improves the yield of devices to

. Upon exposing the fresh device to air, oxygen diffuses into the semiconductor layer interacting with the base electrode, which facilitates the formation of pinholes in the base and creates an insulator layer around the base. Moreover, as oxygen acts as a p-dopants to the p-type semiconductors used in this work, the device performance is further improved, manifesting in an increased on-state current. However, as the exposure time increases, different p-type organic semiconductors show different behavior depending on their ionization potential. Comparing two semiconductor materials with a difference in their ionization potential of 0.4 eV, we show that long-term degradation could be effectively suppressed. Therefore, the positive effect of air exposure could be utilized to optimize p-type OPBTs, which offers a simple and universal way to construct high performance p-type OPBTs and possibly also complementary circuits.

Published: May 2023

Abstract
Academic online social work (SW) education has developed over the decades, fully transitioning to it following the COVID-19 pandemic. Studies have examined the emotional responses, coping strategies and resilience of faculty and students to this transition. Our aim is to examine online education experiences and their meaning for faculty and SW students following the COVID-19 pandemic. Semi-structured qualitative interviews were audio-recorded, transcribed verbatim and analysed based on principles of thematic analysis. Interviewees included fifteen SW students and fifteen faculty members at schools of SW (n = 30) from universities and colleges throughout Israel, who also participated in a quantitative survey addressing online SW education. Findings include two themes: (i) Between the illusion of intimacy and the illusion of anonymity: Is it so? (ii) Experiences of difficulty, acceptance and choice relating to online education interactions. Both themes refer to interpersonal dimensions of communication and contact between faculty and students and among students. The desire to preserve a traditional education format versus openness to the online platform is discussed using critical reflexivity. Alternative education programmes combining the two should be developed. The unique and deceptive interplay between intimacy and anonymity in the online space should be considered in courses relying on interpersonal interaction and self-disclosure.

AbstractAdvancements in deep learning algorithms over the past decade have led to extensive developments in brain–computer interfaces (BCI). A promising imaging modality for BCI is magnetoencephalography (MEG), which is a non-invasive functional imaging technique. The present study developed a MEG sensor-based BCI neural network to decode Rock-Paper-scissors gestures (MEG-RPSnet). Unique preprocessing pipelines in tandem with convolutional neural network deep-learning models accurately classified gestures. On a single-trial basis, we found an average of 85.56% classification accuracy in 12 subjects. Our MEG-RPSnet model outperformed two state-of-the-art neural network architectures for electroencephalogram-based BCI as well as a traditional machine learning method, and demonstrated equivalent and/or better performance than machine learning methods that have employed invasive, electrocorticography-based BCI using the same task. In addition, MEG-RPSnet classification performance using an intra-subject approach outperformed a model that used a cross-subject approach. Remarkably, we also found that when using only central-parietal-occipital regional sensors or occipitotemporal regional sensors, the deep learning model achieved classification performances that were similar to the whole-brain sensor model. The MEG-RSPnet model also distinguished neuronal features of individual hand gestures with very good accuracy. Altogether, these results show that noninvasive MEG-based BCI applications hold promise for future BCI developments in hand-gesture decoding.
Utility of Intestinal Ultrasound in Clinical Decision-Making for Inflammatory Bowel Disease
Authors: Saleh Adam , Abraham Bincy P 
Published: May 2023

Abstract

Background
There is a clinical need to improve the monitoring of inflammatory bowel disease (IBD) activity. Despite being used regularly in European countries, intestinal ultrasound (IUS) has been implemented less in the United States for unclear reasons.

Aims
The aim of this study is to illustrate how IUS can be used as a clinical decision-making tool in an American IBD cohort.

Methods
This retrospective cohort analysis evaluated patients with IBD seen at our institution who underwent IUS as part of routine evaluation of their IBD from July 2020 to March 2022. To evaluate the clinical utility of IUS for different patient populations and against more frequently used measures of inflammation, we compared patient demographics, inflammatory markers, clinical scores, and medications between patients in remission and those with active inflammation. Treatment plans between the 2 groups were compared and we analyzed patients with follow-up IUS visits to validate treatment plan decisions at initial evaluation.

Results
Out of 148 total patients with IUS, we found that 62.1% (N = 92) of our patients had active disease and 37.9% (N = 56) were in remission. Ulcerative colitis activity index and Mayo scores were both significantly correlated with IUS findings. The treatment plan was significantly correlated with IUS findings (P = .004). At follow-up, we observed an overall decrease in intestinal thickening, improvements in vascular flow, and mural stratification.

Conclusions
Clinical decisions incorporating IUS findings effectively reduced inflammation in our IBD patients. IUS should be strongly considered by IBD clinicians in the United States for monitoring disease activity in IBD.

Published: May 2023

AbstractAimsA diverse set of factors influence cardiovascular diseases (CVDs), but a systematic investigation of the interplay between these determinants and the contribution of each to CVD incidence prediction is largely missing from the literature. In this study, we leverage one of the most comprehensive biobanks worldwide, the UK Biobank, to investigate the contribution of different risk factor categories to more accurate incidence predictions in the overall population, by sex, different age groups, and ethnicity.Methods and resultsThe investigated categories include the history of medical events, behavioural factors, socioeconomic factors, environmental factors, and measurements. We included data from a cohort of 405 257 participants aged 37–73 years and trained various machine learning and deep learning models on different subsets of risk factors to predict CVD incidence. Each of the models was trained on the complete set of predictors and subsets where each category was excluded. The results were benchmarked against QRISK3. The findings highlight that (i) leveraging a more comprehensive medical history substantially improves model performance. Relative to QRISK3, the best performing models improved the discrimination by 3.78% and improved precision by 1.80%. (ii) Both model- and data-centric approaches are necessary to improve predictive performance. The benefits of using a comprehensive history of diseases were far more pronounced when a neural sequence model, BEHRT, was used. This highlights the importance of the temporality of medical events that existing clinical risk models fail to capture. (iii) Besides the history of diseases, socioeconomic factors and measurements had small but significant independent contributions to the predictive performance.ConclusionThese findings emphasize the need for considering broad determinants and novel modelling approaches to enhance CVD incidence prediction.
Reporting completeness of scoping reviews in orthodontic literature up to 2022. An empirical study
Authors: Mikelis Filippos , Koletsi Despina 
Published: May 2023

Summary

Aim
To assess the quality of reporting of Scoping Reviews (ScRs) in Orthodontics according to the PRISMA Extension Checklist for Scoping Reviews (PRISMA-ScR). Our secondary aim was to identify publication characteristics, such as year of publication, journal, inclusion of a reporting guideline, and study registration, associated with ScRs reporting quality.

Materials and Methods
Pubmed, Scopus, and Web of Science Core Collection were searched as of 1 August 2022 for identification of orthodontic ScRs. This was supplemented by electronic searches within the contents of eleven specialty journals. The item-specific and overall reporting quality score of the examined orthodontic ScRs, based on the PRISMA Extension Checklist for Scoping Reviews were recorded. Association of reporting quality score with publication characteristics was further examined.

Results
A total of 40 ScRs were identified and included, with a mean reporting quality score of 73.0 per cent (standard deviation = 14). The majority of studies were published from 2020 onwards (32/40; 80.0%). Of the most adequately reported items were the summary of the evidence description in the Discussion (38/40; 95.0%) and the selection of the sources of evidence in the Results section (34/40; 85.0%). Protocol registration and reporting of limitations were missed in almost half of the ScRs (19/40; 47.5%), while less than half studies were adequately justified (18/40; 45.0%). According to the multivariable linear regression, adherence to appropriate reporting guidelines resulted in improved reporting quality score by 10 per cent (β-coefficient: 0.10; 95% CI: 0.002, 0.19; P = 0.04), conditional on year and journal of publication. Year, journal of publication, and registration practices did not appear as significant predictors (P &gt; 0.05 in all instances).

Conclusions
The reporting quality of the examined orthodontic ScRs was suboptimal, with questionable justification for their conduct and certain items being mostly affected.
Wealth, health and inequality in Agta foragers
Authors: Page Abigail E , Ruiz Milagros , Dyble Mark , Major-Smith Daniel , Migliano Andrea B , Myers Sarah 
Published: May 2023

AbstractBackground and objectivesThere is significant evidence from large-scale, industrial and post-industrial societies that greater income and wealth inequality is negatively associated with both population health and increasing health inequalities. However, whether such relationships are inevitable and should be expected to impact the health of small-scale societies as they become more market-integrated is less clear.MethodologyHere, using mixed-effect models, we explore the relationship between health, wealth, wealth inequality and health inequalities in a small-scale foraging population from the Philippines, the Agta.ResultsAcross 11 camps, we find small to moderate degrees of wealth inequality (maximal Gini Coefficient 0.44) which is highest in the most permanent camps, where individuals engage more heavily in the formal market. However, in both adults (n = 161) and children (n = 215), we find little evidence that either wealth or wealth inequality associates with ill health, except for one measure of nutritional condition—red blood cell count.Conclusions and implicationsWe interpret these results in the light of high levels of cooperation among the Agta which may buffer against the detrimental effects of wealth inequality documented in industrial and post-industrial societies. We observe little intergenerational wealth transmission, highlighting the fluid nature of wealth, and thus wealth inequality, particularly in mobile communities. The deterioration of nutritional status, as indicated by red blood cell counts, requires further investigation before concluding the Agta’s extensive cooperation networks may be beginning to breakdown in the face of increasing inequality.
Tracking Climate Securitization: Framings of Climate Security by Civil and Defense Ministries
Authors: Vogler Anselm 
Published: May 2023

Abstract
Defense ministries regularly frame climate security in their national security strategies. Recently, “civil” ministries also begun mentioning climate security. However, they do not mean the same thing. This article develops four indicators to assess the commitment of climate security framings to an understanding of climate security as either human/environmental or national security issue. It applies the indicators to fifty submissions of Nationally Determined Contributions (NDC) by civil ministries and seventy defense publications. The paper finds that NDC commonly refer to climate changes’ anthropogenic origins and biophysical impacts but rarely to indirect consequences such as migration or conflict. In contrast, military administrations rarely mention anthropogenic origins but warn more often than NDC of indirect consequences. This shows that a civil domestic discourse on climate security has emerged, more attuned to human security and environmental security and more conducive to climate change mitigation and adaptation. The paper argues that organizational theory can explain these differences in securitization: defense and civil ministries frame climate security differently so that it falls in line with their respective mandates and established organizational features. The article concludes with a checklist for assessing framings of climate security.

Abstract
The present study was conducted to assess the effect of different processing techniques of broken rice on processing quality of pellet feed, growth performance, nutrient digestibility, blood biochemical parameters, and fecal microbiota of weaned piglets. A total of 400 crossbred piglets (Duroc × Landrace × Yorkshire) with a mean initial body weight (BW) of 7.24 ± 0.52 kg were used in a 28-d experiment. Piglets were randomly distributed to one of 4 treatment and 10 replicate pens per treatment, with 10 piglets per pen. The dietary treatments were as follows: CON, corn as the main cereal type in the dietary; BR, 70% of the corn replaced by broken rice; ETBR, 70% of the corn replaced by extruded broken rice; EPBR, 70% of the corn replaced by expanded broken rice. Extruded broken rice and expanded broken rice supplementation significantly (P &lt; 0.05) increased hardness, pellet durability index, crispness, and starch gelatinization degree. Extruded broken rice and expanded broken rice generated a higher (P &lt; 0.05) average daily feed intake, increased (P &lt; 0.05) average daily gain, decreased (P &lt; 0.05) feed conversion ratio, and lowered (P &lt; 0.05) the diarrhea rate. Piglets fed extruded broken rice displayed high apparent total tract digestibility levels of dry matter (P &lt; 0.05), gross energy (P &lt; 0.05), crude protein (P &lt; 0.05), and organic matter (P &lt; 0.05). In addition, extruded broken rice and expanded broken rice supplementation had increased Lactobacillus and Bifidobacterium levels in gut, whereas a lower abundance of the potential pathogens Clostridium_sensu_strictio_1 and Streptococcus was observed. Dietary supplementation of extruded broken rice and expanded broken rice failed to show significant effects on blood biochemical parameters. Combined, 70% corn substituted with broken rice failed to show significant effects. Collectively, extruded broken rice and expanded broken rice supplementation had positively enhanced the pellet quality, growth performance, nutrient digestibility, and gut microbiota of weaned piglets.
