AbstractAlthough the goal of rectal cancer treatment is to restore gastrointestinal continuity, some patients with rectal cancer develop a permanent stoma (PS) after sphincter-saving operations. Although many studies have identified the risk factors and causes of PS, few have precisely predicted the probability of PS formation before surgery. To validate whether an artificial intelligence model can accurately predict PS formation in patients with rectal cancer after sphincter-saving operations. Patients with rectal cancer who underwent a sphincter-saving operation at Taipei Medical University Hospital between January 1, 2012, and December 31, 2021, were retrospectively included in this study. A machine learning technique was used to predict whether a PS would form after a sphincter-saving operation. We included 19 routinely available preoperative variables in the artificial intelligence analysis. To evaluate the efficiency of the model, 6 performance metrics were utilized: accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and area under the receiving operating characteristic curve. In our classification pipeline, the data were randomly divided into a training set (80% of the data) and a validation set (20% of the data). The artificial intelligence models were trained using the training dataset, and their performance was evaluated using the validation dataset. Synthetic minority oversampling was used to solve the data imbalance. A total of 428 patients were included, and the PS rate was 13.6% (58/428) in the training set. The logistic regression (LR), Gaussian Naïve Bayes (GNB), Extreme Gradient Boosting (XGB), Gradient Boosting (GB), random forest, decision tree and light gradient boosting machine (LightGBM) algorithms were employed. The accuracies of the logistic regression (LR), Gaussian Naïve Bayes (GNB), Extreme Gradient Boosting (XGB), Gradient Boosting (GB), random forest (RF), decision tree (DT) and light gradient boosting machine (LightGBM) models were 70%, 76%, 89%, 93%, 95%, 79% and 93%, respectively. The area under the receiving operating characteristic curve values were 0.79 for the LR model, 0.84 for the GNB, 0.95 for the XGB, 0.95 for the GB, 0.99 for the RF model, 0.79 for the DT model and 0.98 for the LightGBM model. The key predictors that were identified were the distance of the lesion from the anal verge, clinical N stage, age, sex, American Society of Anesthesiologists score, and preoperative albumin and carcinoembryonic antigen levels. Integration of artificial intelligence with available preoperative data can potentially predict stoma outcomes after sphincter-saving operations. Our model exhibited excellent predictive ability and can improve the process of obtaining informed consent.

AbstractAngular limb deformity (ALD) affects many species of livestock and companion animals. The mechanisms of ALD development are not well understood, but previous research suggests the involvement of genetic risk factors. A case-control genome-wide association study (GWAS) was conducted with 40 ALD-affected and 302 unaffected Rambouillet rams and 40,945 single nucleotide polymorphisms (SNPs). Forelimbs of 6 ALD-affected rams were examined and diagnosed with osteochondrosis. Genome-wide or chromosome-wide significant SNPs were positioned exonic, intronic or within the 3′UTR of genesTSPAN18,NRG3andNOVA2, respectively. These genes have previously described roles related to angiogenesis and osteoblast, osteoclast and chondrocyte proliferation and differentiation, which suggests the possibility for their involvement in the pathogenesis of osteochondrosis. Functional consequences of SNPs were evaluated through transcription factor binding site analysis, which predicted binding sites for transcription factors of known importance to bone growth, including SOX6, SOX9 and RUNX2. The identification of genetic risk factors for ALD may help to improve animal welfare and production in Rambouillet, a breed known to be at risk for ALD development. This study proposes genesTSPAN18,NRG3andNOVA2as targets for further research towards understanding the etiology of ALD in Rambouillet sheep.
The co-evolution of friend and help relationships and their different relationship formation and social influence
Authors: Shin Huiyoung 
Published: September 2023

AbstractThis study examined adolescents’ friend and help relationships to better understand their interrelated nature and the different characteristics of relationship formation and social influence in the behavioral and emotional dimensions of academic engagement. Multiplex networks of friends and helpers were collected (N = 542; Mage = 11.46; 20 classrooms) and analyzed using a multilevel Bayesian social network analysis (multilevel random-coefficients SAOM). The results showed that exchanging help played a role in the formation of friendships, and that friendships provided a relational context wherein help can be exchanged. Observable behavioral academic engagement played a more salient role in the formation of friend and help relationships, and highly engaged (in behavioral) adolescents were more often nominated as helpers. Both the behavioral and emotional dimensions of friends’ and helper’ academic engagement contributed to adolescents’ own behavioral and emotional engagement over time, but the social influence was more salient among friends compared to helpers. These results underscore that examining the dependencies among multiple networks and distinguishing between different dimensions of behavior and emotion are critical to elucidate the complex processes of relationship formation and social influence.

AbstractNiTi is a class of metallic biomaterials, benefit from superelastic behavior, high biocompatibility, and favorable mechanical properties close to that of bone. However, the Ni ion leaching, poor bioactivity, and antibacterial activity limit its clinical applications. In this study, HAp-Nb2O5 composite layers were PC electrodeposited from aqueous electrolytes containing different concentrations of the Nb2O5 particles, i.e., 0–1 g/L, to evaluate the influence of the applied surface engineering strategy on in vitro immersion behavior, Ni2+ ion leaching level, and antibacterial activity of the bare NiTi. Surface characteristics of the electrodeposited layers were analyzed using SEM, TEM, XPS, and AFM. The immersion behavior of the samples was comprehensively investigated through SBF and long-term PBS soaking. Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) infective reference bacteria were employed to address the antibacterial activity of the samples. The results illustrated that the included particles led to more compact and smoother layers. Unlike bare NiTi, composite layers stimulated apatite formation upon immersion in both SBF and PBS media. The concentration of the released Ni2+ ion from the composite layer, containing 0.50 g/L Nb2O5 was ≈ 60% less than that of bare NiTi within 30 days of immersion in the corrosive PBS solution. The Nb2O5-reinforced layers exhibited high anti-adhesive activity against both types of pathogenic bacteria. The hybrid metallic-ceramic system comprising HAp-Nb2O5-coated NiTi offers the prospect of a potential solution for clinical challenges facing the orthopedic application of NiTi.

AbstractThis study aimed to elicit the preferences and willingness-to-pay for blood pressure (BP) telemonitoring programs. This study also investigated the different factors or participant characteristics that could influence preferences and choice behaviors. Participants with hypertension were identified from an online survey panel demographically representative of Singapore’s general population. Participants completed a discrete choice experiment (DCE) with 12 choice sets, selecting their preferred BP monitoring program differing on five attributes: mode of consultation, BP machine type (with Bluetooth or not), BP machine price, monthly fee, and program duration. The base reference population (male, married, higher income, more formal education years, full-time worker, aged 55 to <65 years, and digital skills score of 36) preferred teleconsultation over in-person consultation, Bluetooth feature, lower machine price, lower monthly fee, and shorter program duration. A subgroup of participants can be considered teleconsultation-resistant, and three demographic factors were associated with lower preference for teleconsultation: female, fewer formal education years, and lower income. Considering the reference population and Bluetooth attribute, participants were willing to pay 66 SGD (~49 USD) additional for the machine to obtain the Bluetooth feature. Considering the reference population and teleconsultation attribute, participants were willing to pay 6.80 SGD (~5.10 USD) extra monthly fee for a program using teleconsultation. Here we report that amongst participants with hypertension, there is strong preference for the use of teleconsultation and a BP machine with Bluetooth feature in a BP monitoring program. However, a subgroup of participants are teleconsultation-resistant and would prefer in-person consultation.

AbstractFishing for subsistence constitutes a livelihood safety net for poverty, malnutrition and gender inequality for populations dependent upon aquatic foods around the world. Here we provide global estimates showing that almost the same amount of small-scale fishers engage in subsistence fishing at some point during the year as in commercial employment and use subsistence estimates to measure small-scale fisheries’ livelihood safety net function. In 2016, we estimate that 52.8 million people were engaged in subsistence fishing at some point during the year, while another 60.2 million people were commercially employed (90% of global fisheries employment). From 14 country case studies, it was possible to estimate that the subsistence catch provided an average apparent intake of six nutrients critical for positive health outcomes, equivalent to 26% of the recommended daily nutrient intake for 112.5 million people, higher than the national average contribution of beef or poultry.
Farmer perspectives on carbon markets incentivizing agricultural soil carbon sequestration
Authors: Barbato Clare T. , Strong Aaron L. 
Published: September 2023

AbstractClimate change mitigation efforts to achieve net-zero emissions require not only decreasing current greenhouse gas emissions, but also the deployment of negative emissions technologies. Soil organic carbon sequestration in agricultural lands is one such negative emissions strategy, currently being incentivized predominantly through voluntary carbon offset markets. Through semi-structured interviews, we assess both conventional and organic farmer perspectives on soil carbon offset programs that have been created in the United States since 2017. The perspectives of farmers both participating and not participating in agricultural soil carbon markets were similar and consistent. Farmers in both groups expressed concerns about the convoluted, burdensome and unpredictable nature of receiving offset credits and emphasized that they were implementing practices for their own business interests and sustainability concerns, not the financial incentive of the generation of carbon credits. Based on our research, carbon offset credit payments for agricultural soil carbon sequestration are largely reaching farmers who were already implementing these beneficial practices or were already strongly interested in implementing these practices, and the payments for the offset credits are seen as a ‘gravy on top’, suggesting that these offset markets face strong challenges of ensuring true additionality essential to effective climate mitigation.
A computational text analysis investigation of the relation between personal and linguistic agency
Authors: Simchon Almog , Hadar Britt , Gilead Michael 
Published: September 2023

AbstractPrevious psycholinguistic findings showed that linguistic framing – such as the use of passive voice - influences the level of agency attributed to other people. To investigate whether passive voice use relates to people’s personal sense of agency, we conducted three studies in which we analyzed existing experimental and observational data. In Study 1 (N = 835) we show that sense of personal agency, operationalized between participants as recalling instances of having more or less power over others, affects the use of agentive language. In Study 2 (N = 2.7 M) we show that increased personal agency (operationalized as one’s social media followership) is associated with more agentive language. In Study 3 and its two replications (N = 43,140) we demonstrate using Reddit data that the language of individuals who post on the r/depression subreddit is less agentive. Together, these findings advance our understanding of the nuanced relationship between personal and linguistic agency.
Understanding Internalizing and Externalizing Behaviors in Autistic Toddlers
Authors: Levy Rachel S. , Fipp-Rosenfield Hannah L. , Lee Jordan P. , Grauzer Jeffrey M. , Roberts Megan Y. 
Published: September 2023

Purpose:
The majority of autistic toddlers present with clinically significant levels of internalizing or externalizing behaviors. Despite the prevalence of internalizing and externalizing behaviors in caseloads, the overwhelming majority of speech-language pathologists (SLPs) have not received specialized instruction in how to support children with these behaviors. The purpose of this study was to identify which child and caregiver characteristics are most associated with internalizing and externalizing behaviors in autistic toddlers in order to consider how SLPs may tailor their treatment to better support the individual needs of autistic children.

Method:
Participants included 109 mothers and their autistic children between 18 and 48 months of age. This study was a secondary analysis of data from a randomized clinical trial. Participants' baseline data included a variety of child (i.e., expressive language, receptive language, restricted and repetitive behavior [RRB], and nonverbal cognition) and caregiver (i.e., self-efficacy and responsiveness) characteristics. Seemingly unrelated regressions were conducted to determine which characteristics were associated with internalizing and externalizing behaviors in autistic toddlers.

Results:
Higher RRB scores were associated with both higher internalizing and externalizing behavior scores. A lower nonverbal cognition score was also associated with higher internalizing behavior scores but to a lesser extent than RRB.

Conclusion:
These findings suggest that SLPs may support internalizing and externalizing behaviors in autistic children by taking RRBs and nonverbal cognition into consideration.

Context. We present the computation of global reference frames from very long baseline interferometry (VLBI) observations at the Vienna International VLBI Service for Geodesy and Astrometry (IVS) Analysis Center (VIE) in detail. We focus on the celestial and terrestrial frames from our two latest solutions VIE2020 and VIE2022b.
Aims. The current international celestial and terrestrial reference frames, ICRF3 and ITRF2020, include VLBI observations until March 2018 (at the standard geodetic and astrometric radio frequencies 2.3 and 8.4 GHz) and December 2020, respectively. We provide terrestrial and celestial reference frames including VLBI sessions until June 2022 organized by the IVS.
Methods. Vienna terrestrial and celestial reference frames are computed in a common least squares adjustment of geodetic and astro-metric VLBI observations with the Vienna VLBI and Satellite Software (VieVS).
Results. We provide high-precision celestial and terrestrial reference frames computed from 24 h IVS observing sessions. Our latest celestial reference frame solution VIE2022b-sx provides positions of 5407 radio sources at the frequency of 8.4 GHz. In particular, the positions of sources with few observations at the time of the ICRF3 calculation are improved. The frame also includes positions of 870 radio sources not included in ICRF3. The additional observations beyond the data used for ITRF2020 provide a more reliable estimation of positions and linear velocities of newly established VLBI Global Observing System (VGOS) telescopes.
Infrared spectra of TiO2 clusters for hot Jupiter atmospheres
Authors: Sindel J. P. , Helling Ch. , Gobrecht D. , Chubb K. L. , Decin L. 
Published: September 2023

Context. Clouds appear to be an unavoidable phenomenon in cool and dense environments. Hence, their inclusion is a necessary part of explaining observations of exoplanet atmospheres, most recently those of WASP 96b with the James Webb Space Telescope (JWST). Understanding the formation of cloud condensation nuclei in non-terrestrial environments is therefore crucial in developing accurate models to interpret current and future observations.
Aims. The goal of the paper is to support observations with infrared spectra for (TiO2)N clusters to study cloud formation in exoplanet atmospheres.
Methods. We derived vibrational frequencies from quantum-chemical calculations for 123 (TiO2)-clusters and their isomers and we evaluated their line-broadening mechanisms. Cluster spectra were calculated for several atmospheric levels for two example exoplanet atmospheres (WASP 121b-like and WASP 96b-like) to identify possible spectral fingerprints for cloud formation.
Results. The rotational motion of clusters and the rotational transitions within them cause significant line broadening, so that individual vibrational lines are broadened beyond the spectral resolution of the medium-resolution mode of the JWST mid-infrared instrument (MIRI) at R = 3000. However, each individual cluster isomer exhibits a ‘fingerprint’ IR spectrum. In particular, larger (TiO2) clusters have distinctly different spectra from smaller clusters. The morning and evening terminator for the same planet can exhibit different total absorbances, due to the greater abundance of different cluster sizes.
Conclusions. The largest (TiO2) clusters are not necessarily the most abundant (TiO2) clusters in the high-altitude regions of ultra-hot Jupiters and the different cluster isomers do contribute to the local absorbance. Planets with a considerable day-night asymmetry will be most suitable in the search for (TiO2) cluster isomers with the goal of improving cloud formation modelling.
Automated analysis of oscillations in coronal bright points
Authors: Ramsey B. , Verwichte E. , Morgan H. 
Published: September 2023

Context. Coronal bright points (BPs) are numerous, bright, small-scale dynamical features found in the solar corona. Bright points have been observed to exhibit intensity oscillations across a wide range of periodicities and are likely an important signature of plasma heating and/or transport mechanisms.
Aims. We present a novel and efficient wavelet-based method that automatically detects and tracks the intensity evolution of BPs using images from the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) in the 193 Å bandpass. Through the study of a large, statistically significant set of BPs, we attempt to place constraints on the underlying physical mechanisms.
Methods. We used a continuous wavelet transform (CWT) in 2D to detect the BPs within images. One-dimensional CWTs were used to analyse the individual BP time series to detect significant periodicities.
Results. We find significant periodicity at 4, 8–10, 17, 28, and 65 min. Bright point lifetimes are shown to follow a power law with exponent −1.13 ± 0.07. The relationship between the BP lifetime and maximum diameter similarly follows a power law with exponent 0.129 ± 0.011.
Conclusions. Our wavelet-based method successfully detects and extracts BPs and analyses their intensity oscillations. Future work will expand upon these methods, using larger datasets and simultaneous multi-instrument observations.

Published: September 2023

The purpose of this study is to compare the blow-off pressure of a selection of connectors, tubing and tubing attachment techniques currently available for construction of extracorporeal circuits.
Each connector and tubing combination was filled with H2O and sealed at both ends. Hydrostatic pressure was increased, through a leur side port, until a pressure drop indicated connection failure. Line pressure, P.S.I., was measured with a hydrostatic gauge through a second luer side port.
Blow-off line pressures were inversely proportional to connector and tubing diameter, and directly proportional to tubing wall thickness. Bentley, Cobe, Gics and Shiley connectors were ranked in accordance with blow-off line pressures generated on Bentley, Harvey and Tygon tubing.
