Activity-based Early Autism Diagnosis Using A Multi-Dataset Supervised Contrastive Learning Approach

Autism Spectrum Disorder (ASD) is a neurological disorder. Its primary symptoms include difficulty in verbal/non-verbal communication and rigid/repetitive behavior. Traditional methods of autism diagnosis require multiple visits to a human specialist. However, this process is generally time-consuming and may result in a delayed (early) intervention. In this paper, we present a data-driven approach to automate autism diagnosis using video clips of subjects performing simple activities recorded in a weakly constrained environment. This task is particularly challenging since the available training data is small, videos from the two categories (“ASD” and “Control”) are generally perceptually indistinguishable, and there is no clear understanding of what features would be beneficial in this task. To address these, we present a novel multi-dataset supervised contrastive learning technique to learn discriminative features simultaneously from multiple video datasets with significantly diverse distributions. Extensive empirical analyses demonstrate the promise of our approach compared to competing techniques on this challenging task.
Complexity Hierarchies and Higher-Order Cons-Free Rewriting

Constructor rewriting systems are said to be cons-free if, roughly, constructor terms in the right-hand sides of rules are subterms of constructor terms in the left-hand side; the computational intuition is that rules cannot build new data structures. It is well-known that cons-free programming languages can be used to characterize computational complexity classes, and that cons-free first-order term rewriting can be used to characterize the set of polynomial-time decidable sets. We investigate cons-free higher-order term rewriting systems, the complexity classes they characterize, and how these depend on the order of the types used in the systems. We prove that, for every k >= 1, left-linear cons-free systems with type order k characterize E^kTIME if arbitrary evaluation is used (i.e., the system does not have a fixed reduction strategy). The main difference with prior work in implicit complexity is that (i) our results hold for non-orthogonal term rewriting systems with possible rule overlaps with no assumptions about reduction strategy, (ii) results for such term rewriting systems have previously only been obtained for k = 1, and with additional syntactic restrictions on top of cons-freeness and left-linearity. Our results are apparently among the first implicit characterizations of the hierarchy E^1TIME ! = E^2TIME ! = . Our work confirms prior results that having full non-determinism (via overlaps of rules) does not directly allow for characterization of non-deterministic complexity classes like NE. We also show that non-determinism makes the classes characterized highly sensitive to minor syntactic changes such as admitting product types or non-left-linear rules.

We use the binary cross-entropy and Dice Similarity Coefficient (DSC) losses as the objective function for pre-training.
A Kinetic Study of a Photo-Oxidation Reaction between α-Terpinene and Singlet Oxygen in a Novel Oscillatory Baffled Photo Reactor

By planting LEDs on the surfaces of orifice baffles, a novel batch oscillatory baffled photoreactor (OBPR) together with polymer-supported Rose Bengal (Ps-RB) beads are here used to investigate the reaction kinetics of a photo-oxidation reaction between α-terpinene and singlet oxygen (1O2). In the mode of NMR data analysis that is widely used for this reaction, α-terpinene and ascaridole are treated as a reaction pair, assuming kinetically singlet oxygen is in excess or constant. We have, for the first time, here examined the validity of the method, discovered that increasing α-terpinene initially leads to an increase in ascaridole, indicating that the supply of singlet oxygen is in excess. Applying a kinetic analysis, a pseudo-first-order reaction kinetics is confirmed, supporting this assumption. We have subsequently initiated a methodology of estimating the 1O2 concentrations based on the proportionality of ascaridole concentrations with respect to its maximum under these conditions. With the help of the estimated singlet oxygen data, the efficiency of 1O2 utilization and the photo efficiency of converting molecular oxygen to 1O2 are further proposed and evaluated. We have also identified conditions under which a further increase in α-terpinene has caused decreases in ascaridole, implying kinetically that 1O2 has now become a limiting reagent, and the method of treating α-terpinene and ascaridole as a reaction pair in the data analysis would no longer be valid under those conditions.
Novel Technique to Reconstruct Peri-Implant Keratinised Mucosa Width Using Xenogeneic Dermal Matrix. Clinical Case Series

Reconstruction of sufficient buccal peri-implant keratinised mucosa width (PIKM-W) is reported to reduce the symptoms of peri-implantitis. In order to reduce the drawbacks of autogenous graft harvesting, we investigated a novel porcine dermal matrix (XDM, mucoderm®) using a modified surgical technique for augmentation of PIKM-W. Twenty-four patients were recruited with insufficient (<2 mm) PIKM-W. After split thickness flap preparation, the XDM was trimmed, rehydrated and tightly attached to the recipient periosteal bed using modified internal/external horizontal periosteal mattress sutures via secondary wound healing. Change of the PIKM-W and dimension of the graft remodelling were evaluated at 6 and 12 months postoperatively. The mean PIKM-W changed from 0.42 ± 0.47 to 3.17 ± 1.21 mm at 6 M and to 2.36 ± 1.34 mm at 12 M in the maxilla and from 0.29 ± 0.45 mm to 1.58 ± 1.44 mm at 6 M and to 1.08 ± 1.07 mm at 12 M in the mandible. Graft dimensions decreased by 67.7 ± 11.8% and 81.6 ± 16.6% at 6 M, and continued to 75.9 ± 13.9% and 87.4 ± 12.3% at 12 M, in the maxilla and mandible, respectively. Clinical parameters showed statistically significant intra- and intergroup differences between the baseline and 6 and 12 months (p < 0.05). The present technique using the XDM was safe and successfully reconstructed PIKM-W in both arches. The XDM alone seems to be a suitable alternative to autograft for PIKM-W augmentation in the maxilla.
Statistical Depth in Spatial Point Process

Statistical depth is widely used as a powerful tool to measure the center-outward rank of multivariate and functional data. Recent studies have introduced the notion of depth to the temporal point process, which exhibits randomness in the cardinality as well as distribution in the observed events. The proposed methods can well capture the rank of a point process in a given time interval, where a critical step is to measure the rank by using inter-arrival events. In this paper, we propose to extend the depth concept to multivariate spatial point process. In this case, the observed process is in a multi-dimensional location and there are no conventional inter-arrival events in the temporal process. We adopt the newly developed depth in metric space by defining two different metrics, namely the penalized metric and the smoothing metric, to fully explore the depth in the spatial point process. The mathematical properties and the large sample theory, as well as depth-based hypothesis testings, are thoroughly discussed. We then use several simulations to illustrate the effectiveness of the proposed depth method. Finally, we apply the new method in a real-world dataset and obtain desirable ranking performance.
Perceived climate of Cha-xu and trust on knowledge sharing: a moderated mediation model

Purpose This study aims to identify an antecedent that hinders knowledge sharing, namely, the perceived climate of Cha-xu. Based on the social exchange perspective, the authors propose a theoretical model that links the perceived climate of Cha-xu to employee knowledge sharing. This model focuses on the mediating role of two types of trust (vertical and horizontal trust) and the moderating role of task interdependence in influencing the mediation. Design/methodology/approach Using a sample of 509 Chinese employees, this study carried out a survey on an online platform. This study developed a structural equation model and tested the moderated mediation hypothesis by using Mplus 8.0. Findings The results showed that two types of trust act as mediators in the relationship between the perceived climate of Cha-xu and knowledge-sharing processes. The mediating effect of horizontal trust is stronger. Most significantly, findings show that this mediated relationship is contingent on the level of task interdependence. Originality/value This paper provides evidence for distinguishing vertical trust and horizontal trust in the field of knowledge management. From a managerial perspective, this study identifies traditional cultural factors for hindering knowledge-sharing processes within Chinese organizations.
Kaposiform Hemangioendothelioma of the GI Tract: An Exception to Occam's Principle in an Adult with SBO

Kaposiform hemangioendothelioma (KHE) is a rare and locally aggressive vascular tumor with histological features resembling Kaposi sarcoma and capillary hemangioma mainly occurring in children and adolescents. Approximately 200 cases have been reported since its original description in 1993, with the vast majority presenting at an early age as raised ill-defined lesions with a red-blue hue mainly involving the skin and soft tissues in the extremities. Cases in adults remain extremely rare. Herein, we describe the case of a 29 year-old man who presented with progressive abdominal pain for 4 months and signs of obstipation found to be consistent with small bowel volvulus. The patient underwent exploratory laparotomy and resection of 55 cm of necrotic small bowel followed by enteroenterostomy and anastomosis. Microscopic examination revealed KHE involving small intestinal mesentery, muscularis propria, and submucosa. His recovery was uneventful and he was discharged after stabilization, opting to manage him expectantly with abdominopelvic imaging and to monitor for development of Kasabach-Merritt phenomenon. To our knowledge, this represents the first reported case of this entity presenting as intestinal obstruction in an adult for which we also present a review of the existing literature and possible treatment options.
Effects and Mechanisms of Exercise on Brain-Derived Neurotrophic Factor (BDNF) Levels and Clinical Outcomes in People with Parkinson’s Disease: A Systematic Review and Meta-Analysis

Introduction: Exercise therapy may increase brain-derived neurotrophic factor (BDNF) levels and improve clinical outcomes in people living with Parkinson’s disease (PD). This systematic review was performed to investigate the effect of exercise therapy on BDNF levels and clinical outcomes in human PD and to discuss mechanisms proposed by authors. Method: A search on the literature was performed on PubMed up to December 2023 using the following key words: Parkinson’s disease AND exercise, exercise therapy, neurological rehabilitation AND brain-derived neurotrophic factor, brain-derived neurotrophic factor/blood, brain-derived neurotrophic factor/cerebrospinal fluid AND randomized clinical trial, intervention study. Only randomized clinical trials comparing an exercise intervention to treatment as usual, usual care (UC), sham intervention, or no intervention were included. Results: A meta-analysis of BDNF outcomes with pooled data from five trials (N = 216 participants) resulted in a significant standardized mean difference (SMD) of 1.20 [95% CI 0.53 to 1.87; Z = 3.52, p = 0.0004, I2 = 77%], favoring exercise using motorized treadmill, Speedflex machine, rowing machine, and non-specified exercise. Significant improvements were found in Unified Parkinson’s Disease Rating Scale (UPDRS), UPDRS-III, 6 Minute Walk Test (6MWT), and Berg Balance Scale (BBS). Methodological quality of trials was categorized as “good” in three trials, “fair” in one trial, and “poor” in one trial. Conclusion: Key results of this systematic review are that exercise therapy is effective in raising serum BDNF levels and seems effective in alleviating PD motor symptoms. Exercise therapy confers neuroplastic effects on Parkinson brain, mediated, in part, by BDNF.
Biodegradable Polymers in Veterinary Medicine—A Review

During the past two decades, tremendous progress has been made in the development of biodegradable polymeric materials for various industrial applications, including human and veterinary medicine. They are promising alternatives to commonly used non-degradable polymers to combat the global plastic waste crisis. Among biodegradable polymers used, or potentially applicable to, veterinary medicine are natural polysaccharides, such as chitin, chitosan, and cellulose as well as various polyesters, including poly(ε-caprolactone), polylactic acid, poly(lactic-co-glycolic acid), and polyhydroxyalkanoates produced by bacteria. They can be used as implants, drug carriers, or biomaterials in tissue engineering and wound management. Their use in veterinary practice depends on their biocompatibility, inertness to living tissue, mechanical resistance, and sorption characteristics. They must be designed specifically to fit their purpose, whether it be: (1) facilitating new tissue growth and allowing for controlled interactions with living cells or cell-growth factors, (2) having mechanical properties that address functionality when applied as implants, or (3) having controlled degradability to deliver drugs to their targeted location when applied as drug-delivery vehicles. This paper aims to present recent developments in the research on biodegradable polymers in veterinary medicine and highlight the challenges and future perspectives in this area.
Instructors’ Experiences With the Miscibility of Math and Communication in a Probability and Statistics Course

Three years ago, the University of South Florida’s College of Engineering implemented an interdisciplinary team teaching approach in several courses. The decision to take this approach was motivated by the need to meet expanded general education requirements without increasing the credit hours required of students or the teaching expertise required of faculty. The introductory probability and statistics course was selected for this approach because it is taken College-wide, with five to seven large sections each semester. To provide the expertise needed for this and other courses, the College hired Communication faculty, one of whom is involved with the probability and statistics course. After three years of working together in the course, the authors determined that an evaluation of both our approach to team teaching and what it meant for how we presented material to the students was needed to continue improving student outcomes. We undertook a focused examination of the literature in Engineering and other disciplines on team teaching to better understand this andragogical approach. We determined that Davis’ [1] interdisciplinary team teaching frame and criteria for teaching evaluation provided a collective lens for examining how we were working together and how that affects our students’ learning outcomes for all of the material we include as part of the course. With this lens in mind, we share the story of our course’s evolution as we reflect on our personal experiences. Stories of teaching experiences provide an important resource for other faculty; simultaneously, stories provide a format for examining ongoing teaching practices for the authors. This paper overlays stories of our current practices onto Davis’ degrees of collaboration for team teaching to evaluate improving our teaching together. From this, we developed our plans for moving forward based on the examination of Davis’ interdisciplinary teaching practices. We specifically focus on the degrees of collaboration in the four dimensions Davis describes: planning, teaching, testing and evaluation, and content integration. We share them to provide a resource for others who may be implementing team teaching in situations with some or all of the same parameters.
Intention to Transition: Natural Rubber Smallholders Navigating the Risks of Farming

This study delves into the decision-making dynamics of Indonesian rubber farmers amidst a significant agricultural transition from traditional rubber farming to diverse agricultural practices. Anchored in the Theory of Planned Behavior (TPB) and Protection Motivation Theory (PMT), this research elucidates the multifaceted interplay of the psychological, social, and environmental factors influencing these transitions. Utilizing Structural Equation Modeling (SEM) to analyze data from structured interviews and questionnaires, this study presents a nuanced understanding of how a higher awareness of the risks associated with rubber farming negatively impacts farmers’ attitudes, adherence to social norms, and perceived behavioral control. The findings reveal that while heightened risk understanding and threat appraisal motivate a shift towards alternative agricultural practices, factors like community norms and perceived behavioral control significantly deter this transition. This research contributes a novel integration of the TPB and PMT in the context of agricultural decision making, offering pivotal insights for stakeholders and policymakers aiming to foster sustainable agricultural practices and navigate the complex socio-economic landscape of Indonesia’s agricultural sector.
High-Efficiency and Full Range ZVS Single-Stage Semi-DAB AC–DC Converter With Improved Modulation and Variable Frequency Control

In this article, an improved modulation and variable frequency control strategy for a single-stage high-frequency isolated semi-dual-active-bridge-based ac–dc converter is proposed, which can achieve full operating range (the entire ac line cycle and full-load range) zero-voltage switching (ZVS) and high efficiency. Compared with the basic variable frequency control, an improved variable frequency strategy can reduce the envelope of leakage inductor peak current and reduce the dependence and sensitivity to the load power. More accurate ZVS criteria in view of the magnetizing inductor Lm are proposed. Seven operating modes are adopted and the transition among them is seamless. Three control variables are used in every mode. Wide voltage conversion gain and high-quality grid-side ac current can be obtained without mandatory current-tracking loops. In addition, detailed comparisons among different control strategies and different mode operating regions are analyzed. The design of the transformer and inductor is not affected at all despite the switching frequency varies. A 250-W experimental prototype was built to verify the effectiveness of the proposed improved variable frequency control strategy.
Characteristics and Origin of Tight Oil Accumulations in the Upper Triassic Yanchang Formation of the Ordos Basin, North‐Central China

The Upper Triassic oil accumulations in the Ordos Basin is the most successful tight oil play in China, with average porosity values of less than 10% and permeability values below 1.0 mD. This study investigated the geological characteristics and origin of the tight oil accumulations in the Chang 6 member of the Upper Triassic Yanchang Formation in the Shanbei area based on over 50, 000 petrological, source‐rock analysis, well logging and production data. The tight oil accumulation of the Chang 6 member is distributed continuously in the basin slope and the centre of the basin. The oil‐water relationships are complex. Laumontite dissolution pores are the most important storage spaces, constituting 30%‐60% of total porosity and showing a strong positive relationship with oil production. The pore‐throat diameter is less than 1 µm, and the calculated critical height of the oil column is much larger than the tight sand thickness, suggesting that the buoyancy was probably of limited importance for oil migration. The pressure difference between the source rocks and sandstone reservoirs is inferred to have provided driving force for hydrocarbon migration. Two factors of source‐reservoir configuration and laumontite dissolution contributed to the formation of the Chang 6 tight oil accumulations. Intense hydrocarbon generation and continuous sand bodies close to the hydrocarbon kitchen are the foundation for the large‐scale oil distribution. Dissolution of feldspar‐laumontite during the process of organic matter evolution generated abundant secondary pores and improved the reservoir quality.
HYDRO-ECOLOGICAL EFFECTS OF CITRUS LAND UNDER VEGETATION MEASURES OF SOIL AND WATER CONSERVATION IN RED-SOIL SLOPE

Runoff and sediment characteristics of citrus land under vegetation measures were evaluated based on different standard runoff plots experiments from 2001 to 2008 in Jiangxi Provincial Soil and Water Conservation Eco-science Park.Soil water conditions and their dynamics were also analyzed according to soil moisture data measured in 2010.Soil and water conservation benefits of bermudagrass(Cynodon dactylon) strip covered,bermudagrass full covered and orchard clean tillage were studied.Results showed that the amount of runoff and sediment of citrus plots covered with grass was less than that of clean tillage obviously.The effects of bermudagrass strip covered was best,accounting 98.21 percent in reducing runoff and 99.84 percent in reducing sediment loss.In most soil depth,the soil moisture content of citrus land covered with grass strip was higest and higher than clean tillage measures;while the soil moisture of grass full covered was lower than that of grass strip covered because of water consumption caused by plant transpiration.Grass strip was an effective measure for citrus woodland soil erosion control and played a significant role on runoff and sediment reduction and the accumulation of moisture.
