Kernel-free double well potential support vector regression
Authors: Wei Dong , Yang Zhixia , Ye Junyou 
Published: March 2023

Abstract
In this paper, for the regression problem, a novel kernel-free support vector regression based on the double well potential function (DWPSVR) is proposed.In fact, our model applies a type of kernel-free technique, which directly find a double well potential function to fit data, so that the regression function has geometric diversity. The principle of maximizing G-margin is used to construct our optimization problem, where G-margin is independent of the data and is an approximation of the relative geometric margin. At the same time, the ε-insensitive loss function is introduced. In addition, the primal and dual problems of our model are convex quadratic programming problems, so they can be solved directly. The existence and uniqueness of the optimal solution to both primal and dual problems and some concepts of support vectors are also addressed in theoretical analysis. The 5 artificial and 10 benchmark datasets are utilized in numerical experiments. The experimental results validate that the regression function obtained by our method has geometric diversity and the comprehensive performance of our method outperforms the linear support vector regression model and two kernel-free quadratic regression models.

Published: March 2023

Abstract
Post-combustor is one of the attractive technologies to control pollution by burning the leftover by-products of combustion in an IC engine. An experimental test was conducted on a single-cylinder 150 cc carbureted engine with a post-combustor installed on the exhaust line after the catalytic converter. The post combustor is equipped with a glow plug that heats up to 800˚ C in 2 seconds using a 12-volt battery. A portable emission tester was used to measure the amount of carbon monoxide, hydrocarbon, and oxides of nitrogen. The ambient temperature varied from 20 degrees Celsius to 26 degree Celsius and humidity was 36% during the course of the study. The test result shows that there was no difference in thermal efficiency and brake fuel consumption decrease in the level of unburned hydrocarbon carbon monoxide and oxides of Nitrogen.

Abstract
Dihydromyricetin (DMY) is a natural flavonoid with anti-nonalcoholic steatohepatitis (NASH) activity. However, the effects of DMY on the composition of lipids and bile acids (BAs) in serum, and gut microbiota (GM) in ileum of mice with NASH are not clear. Herein, after male C57BL/6 mice were fed with methionine and choline deficiency (MCD) diet and simultaneously administered with DMY (300 mg/kg/day) by gavage for 8 weeks, the pathological changes of liver tissue were observed by Oil Red O, hematoxylin eosin and Masson staining, the levels of serum AST, ALT and liver TG, MDA were detected by the detection kits, the composition and contents of serum lipids and BAs were detected by LC-MS, the mRNA levels of hepatic BAs homeostasis-related genes were detected by RT-qPCR, and microbiological diversity in ileum was analyzed by 16S rDNA sequencing. The results showed the significant changes including 28 lipids, 4 BAs (23-norDCA, UCA, 7-KDCA and CA), 2 BAs transporters (Mrp2 and Oatp1b2) and 3 GMs (Actinobacteria, Akkermansiaand Faecalibaculum) between MCD and DMY groups. Among them, DMY treatment significantly down-regulated 21 lipids, 4 BAs mentioned above, Faecalibaculum abundance and the ratio of Firmicutes/Bacteroidota, significantly up-regulated 7 lipids and 2 GM (Actinobacteria andAkkermansia). The results suggested that DMY alleviated NASH by up-regulating intestinal probiotics (Actinobacteria and Akkermansia, etc) and inhibiting intestinal harmful bacteria (Erysipelotrichaceaeand Faecalibaculum), thereby regulating the composition and contents of serum BAs and lipids in MCD mice.

Abstract
The photocatalysis is a promising strategy for the water purification. In this work, Cerium dioxide Nano-particles (CeO2-NPs) were deposited by chemical electroless deposition on silicon nanowires (Si-NWs) elaborated by metal-assisted chemical etching. The obtained thin films were characterized by the combined SEM / EDX analysis. The cubic CeO2 phase was identified by X-ray diffraction (XRD) and characterized by photoluminescence (PL) while the chemical states of elements were analyzed by X-ray photoelectron spectroscopy (XPS). The optical gap (2.63–2.87 eV) were determined by UV–Vis spectrophotometry, in conformity with the white-yellow coloration. The Si-NWs/CeO2NPs Nano-composites were successfully applied as photocatalyst for the oxidation of Rhodamine B (Rh B), a recalcitrant dye under visible irradiation. The Si-NWs/CeO2 films showed a higher photocatalytic performance with a quasi total discoloration within 75 min against only 67.5% for Si-NWs. The radical trapping tests showed that the electrons (e−), •OH, O2•− and holes (h+) are mainly involved in the Rh B degradation; a reaction mechanism was suggested and discussed. This work provides new idea to develop an efficient photocatalyst to eliminate emerging pollutants from aquatic environment.
Stochastic dual epidemic hypothesis model with Ornstein-Uhlenbeck process: Analysis and numerical simulations with SARS-CoV-2 variants
Authors: Shi Zhenfeng , Jiang Daqing 
Published: March 2023

Abstract
As it is widely known, the spread of infectious diseases can result in significant socioeconomic consequences and pose a threat to public health. However, biologically plausible models that incorporate stochastic interference and dual epidemic hypotheses have received limited attention. This paper aims to bridge this gap by examining a stochastic dual epidemic hypothesis model that incorporates Ornstein-Uhlenbeck processes to perturb the nonlinear incidence rate. We provide a rigorous analysis of the model, first proving the existence and uniqueness of global solution. We also analyze sufficient conditions for the extinction or persistence of each disease. Additionally, we establish the existence of an ergodic stationary distribution and derive expressions for the normal distribution followed by the global solution around the endemic equilibrium. Finally, using several numerical experimental examples, we validate our theoretical results with the case of dual variants of SARS-CoV-2 that can simultaneously infect humans. This paper contributes to the understanding of stochastic dual epidemic hypotheses and provides a foundation for future research in this field.
Improving ride comfort and road friendliness of heavy truck using semi-active suspension system
Authors: Li Hao , Nguyen Vanliem 
Published: March 2023

To enhance the ride comfort and improve the road friendliness of the heavy truck, based on the dynamic model of the heavy truck, the semi-active suspension system of the vehicle is proposed and controlled based on the fuzzy logic control and Matlab/Simulink software. The efficiency of the semi-active suspension system is then evaluated based on the indexes of the root mean square acceleration of the driver’s seat, the root mean square acceleration of the cab's pitching angle, and the dynamic load coefficient of the wheel axles. The results show that with the semi-active suspension system of the heavy truck controlled by the fuzzy logic control, the acceleration responses of the heavy truck and the dynamic forces of the wheel axles are greatly reduced in comparison with the passive suspension system under various operating conditions of the loads and speeds. Especially, with the semi-active suspension system controlled by the fuzzy logic control, the root mean square accelerations of the driver’s seat and cab pitch angle; and the dynamic load coefficient at 2nd axle of the wheel are clearly reduced by 23.7 %, 27.2 %, and 20.9 % in comparison with the passive suspension system, respectively. Thus, both ride comfort and road friendliness of the heavy truck are improved by the semi-active suspension system. In addition, the vehicle load insignificantly affects ride comfort. However, it greatly affects the road damage, especially with the half load condition of the vehicle. Thus, to improve road friendliness, the full load condition of the vehicle should be used.

We evaluated the effect of different dietary Tithonia diversifolia (TD: 0, 10, 20, and 30 %) on productive traits, egg quality, and economic efficiency in laying hens. Feed intake was higher in hens fed the 20 and 30 % TD diets (120.6 and 119.0 g/day) compared with those fed the 0 or 10 % TD diets (P < 0.0010). Feed egg weight conversion increased with dietary TD inclusion (P < 0.0010). The laying rate was higher (P < 0.0020) in hens on 0 and 10 % TD diets (94.5 and 94.6 %, respectively) than those on 20 and 30 % TD diets (89.7 and 84.9 %). Eggs and yolks were heavier in hens fed 0, 10, and 20 % TD compared with those fed the 30 % TD diet (P <0.0020 and P < 0.0040, respectively), which also had poorer albumen width (P < 0.0010). The yolk had a more intense yellow as the level of dietary TD increased (P < 0.0001). Dietary TD did not affect economic efficiency. In summary, the inclusion of up to 10 % TD in laying hen diets seems feasible as it did not affect productive traits, economic efficiency, and egg quality traits.
Implementación de tromboelastografía para evitar la transfusión de plasma fresco congelado en neonatos
Authors: Soto-Manzano Anggy Valentina 
Published: March 2023

Introducción: actualmente, la indicación principal para la transfusión de FFP es corregir la deficiencia de los factores de coagulación en pacientes con hemorragia activa o sugestión de esta, sin embargo, la práctica clínica ha demostrado que un porcentaje grande de las transfusiones de FFP en neonatología no siguen las recomendaciones de las guías actuales y, en su mayoría, son innecesarias.
Objetivo: ampliar el conocimiento que se tiene sobre la transfusión de FFP en neonatología y la implementación de la tromboelastografía para evitar realizar estas intervenciones.
Metodología: se realizó una revisión de la literatura en la base de datos PubMed y Elsevier, usando palabras clave como tromboelastografía, transfusión de plasma en neonatos, hemostasia neonatal.
Conclusión: se evidenció que los tiempos de coagulación de los neonatos y prematuros sanos son más prolongados en comparación a los adultos, por ello facilita su errada cuando se habla de transfusión de FFP, de ahí que la TEG sea una buena herramienta para evaluar el estado coagulante de los neonatos de manera integral, sin abrir paso a errores de interpretación y facilitando la decisión de tratamientos en los pacientes en UCIN, antes de requerir transfusiones de FFP.
Effects of orthodontic camouflage treatment vs orthodontic-orthognathic surgical treatment on condylar stability in Class II hyperdivergent patients with severe temporomandibular joint osteoarthrosis: a retrospective observational study
Authors: Tian Yajing , Mao Bochun , Cui Shengjie , Guo Yanning , Zhao Ningrui , Zhang Yidan , Zhou Yanheng , Wang Xuedong 
Published: March 2023

ABSTRACT

Objectives
To investigate the differences in profile changes and stability of the condyles between orthodontic camouflage treatment assisted by vertical control and that accomplished via orthognathic surgery in Class II hyperdivergent patients with TMJ osteoarthrosis (TMJOA).

Materials and Methods
This study included 27 Class II hyperdivergent TMJOA patients (54 condyles) who received orthodontic camouflage treatment (13 patients) or orthognathic surgery (14 patients) Cone-beam computerized tomography (CBCT) scans were taken before treatment (T1) and 1 year after treatment (T2). Cephalometric and TMJ measurement analyses were conducted to evaluate the change in profile and condyles from T1 to T2 using independent samples t-test and paired t-test. Three-dimensional (3D) deviation analysis was also performed to evaluate the stability of condyles from T1 to T2.

Results
Both groups showed significant profile improvement from T1 to T2. The changes in Z angle and ANB angle were larger in the surgical group than in the orthodontic group. Condylar width, length, and height remained stable after treatment in the orthodontic group (P &gt; .05), while they reduced by 0.67 ± 0.85 mm, 1.14 ± 1.10 mm, and 1.07 ± 1.34 mm, respectively, in the surgical group (P &lt; .05). Superior, posterior, medial, and lateral joint spaces were significantly reduced in the orthodontic group (P &lt; .05). 3D deviations intuitively showed that condylar bone in the orthodontic group was more stable than that in the surgical group.

Conclusions
For Class II hyperdivergent patients with severe TMJOA, orthodontic camouflage treatment with vertical control can effectively maintain the stability of condyles while significantly improving the profile. Surgical treatment yields a better profile but may increase the risk of condyle resorption.
Scottish Education: Between the UK and the Nordic
Authors: Adams Paul 
Published: March 2023

The (re)opening of the Scottish Parliament in 1999 cemented calls for small state self-management, particularly along Nordic lines, both to reflect the desire for independence and belief that small states prosper when aligned with similar jurisdictions. However, whether there is a ‘Nordic education approach’ is questionable. Further, this positioning assumes certain things about Scotland, ‘The Scottish’, and the Scottish education system. Rather than present Scottish education as aligning with Norden, it is better to identify pushes and pulls between northern countries and internal/UK factors. This paper examines educational exigencies: pushes and pulls from the Nordic countries and the UK.

El propósito del presente estudio fue identificar el nivel de competencia moral en los estudiantes de tecnologías y evaluar si existe una diferencia de género. El presente estudio tuvo un enfoque cuantitativo descriptivo; se ponderó el nivel de la competencia moral de los estudiantes de tecnologías. Debido a que se evaluó en un solo momento, fue transaccional y no experimental. Los participantes fueron 1389 estudiantes de ambos géneros: 738 mujeres y 651 hombres, voluntarios de una universidad tecnológica de Tabasco, México. El cuestionario aplicado para evaluar el juicio moral de los estudiantes fue el “Cuestionario moral emocional”, que evalúa el juicio moral a partir de la culpa y el orgullo. La competencia moral de los participantes arrojó un valor promedio de 32 % (DE = 20 %). Con respecto al género, la competencia moral en mujeres fue de 31.5 % y los hombres obtuvieron un valor de 32.8 %. Los resultados de este estudio hacen posible una evaluación eficaz sobre la actuación y competencia moral de los estudiantes de tecnología. Esta investigación es un precedente para nuevos estudios que permitan identificar el índice de competencia moral emocional de los individuos y con ello contribuir a la disminución de conductas no deseadas en los estudiantes.
Correlation Between Total Nasal Symptoms Score (TNSS) and Quality of Life of Chronic Rhinosinusitis Patients in ENT Outpatient Clinic of Prof. Dr. I.G.N.G Ngoerah General Hospital Denpasar in 2021
Authors: Wahyu Widiantari I Gusti Ayu Putu , Ratnawati Luh Made 
Published: March 2023

Introduction: Rhinosinusitis is an inflammation of the nasal mucosa and paranasal sinuses. Acute rhinosinusitis that is not treated properly can progress to chronic rhinosinusitis. Chronic rhinosinusitis can lead to impaired quality of life. Until now there is no data regarding the relationship of TNSS to the quality of life of patients with chronic rhinosinusitis based on SNOT-22, therefore researchers want to conduct research on the relationship of TNSS to the quality of life of patients with chronic rhinosinusitis based on SNOT-22.

Methods: This study was a retrospective analytical study with a cross-sectional study design.

Results: There was a significant relationship with a strong correlation (r=0.724) between TNSS and the quality of life of chronic rhinosinusitis patients.

Conclusion: There was a significant relationship with a strong correlation (r=0.724) between TNSS and the quality of life of chronic rhinosinusitis patients at Prof. Dr. I.G.N.G Ngoerah General Hospital Denpasar.
Goats diagnosed with neoplasia display variability in clinical presentations, treatments, and outcomes
Authors: Krus Catherine B. , Mullins Caitlyn , Oman Rachel 
Published: March 2023

Abstract

OBJECTIVE
To describe clinical presentation, treatment, and short- and long-term outcomes of goats diagnosed with neoplasia.

ANIMALS
46 goats with a definitive diagnosis of ≥ 1 neoplastic process admitted over a 15-year period.

PROCEDURES
Medical records for all goats admitted to the Colorado State University Veterinary Teaching Hospital over a 15-year period were reviewed to identify animals diagnosed with neoplasia. Signalment, presenting complaint, duration of clinical signs, diagnostic testing, treatment, and short-term outcomes were recorded. When available, long-term follow-up data were collected via email or telephone interview with owners.

RESULTS
46 goats with 58 neoplasms were identified. The prevalence of neoplasia within the study population was 3.2%. The most commonly diagnosed neoplasms were squamous cell carcinoma, thymoma, and mammary carcinoma. The Saanen breed was the most common breed noted in the study population. Evidence of metastasis was found in 7% of the goats. Long-term follow-up was available in 5 goats with mammary neoplasia that underwent bilateral mastectomy. No evidence of mass regrowth or metastasis was noted in any of the goats 5 to 34 months postoperatively.

CLINICAL RELEVANCE
Goats are increasingly treated as companion rather than strictly production animals, making it important for veterinarians to provide more evidence-based and advanced clinical care. This study provided a clinical overview of presentation, treatment, and outcome for goats diagnosed with neoplasia and highlighted the challenges associated with the wide variety of neoplastic processes affecting goats.
Formal instruction and continuing education engagement as factors improving small animal general practitioners discussing nutrition with clients
Authors: Alvarez Elizabeth E. , Schultz Kelly K. , Floerchinger Amanda M. , Hull Jennifer L. 
Published: March 2023

Abstract

OBJECTIVE
Evaluate whether general practitioners’ formal small animal (canine and feline) nutrition instruction in veterinary school and the amount and type of continuing education engagement affect perceived self-reported confidence and frequency in discussing nutrition with clients.

SAMPLE
403 small animal veterinarians who responded to an online survey distributed through the American Animal Hospital Association.

PROCEDURES
Veterinarians were surveyed regarding perceived amount of formal instruction received in veterinary school, interest, time committed to self-education, and confidence in both self and staff knowledge in small animal nutrition.

RESULTS
Of those veterinarians who responded to the survey, 57.1% (201/352) reported they received “none” or “very little” formal instruction in small animal nutrition, while 151 of 352 answered “some” or “a significant amount.” Veterinarians with more formal instruction and veterinarians who reported spending more time in self-education had increased confidence in their own nutritional knowledge (P < .01) and that of their staff (P < .01).

CLINICAL RELEVANCE
Veterinarians with self-reported significant formal instruction and veterinarians with higher continuing education engagement were more confident in their knowledge and their staff’s knowledge regarding therapeutic and nontherapeutic small animal nutrition. Therefore, it is important for the profession to address veterinary nutrition education gaps in order to increase the veterinary healthcare team’s engagement in nutritional discussions with their clients for both healthy and sick pets.
The Use of Public Space During the Epidemic

Published: March 2023

ABSTRACT
At the beginning of this article, it was shown that the indicators of the current so-called social distance determined by decision-makers at various stages of the epidemic development are imprecise, do not sufficiently take into account spatial relations, are unclear in public perception, and do not contain specific practical solutions. Therefore, this study undertakes the task of giving the term “social distancing” precise features, defined on the basis of geometry, and providing solutions in typical cases of the living space of the population. The geometry of the distribution of people in various situations of everyday life was considered: people standing during concerts or religious ceremonies, sitting during meals in collective catering rooms and participating in lectures, cultural, entertainment or sports events. In the latter group of tasks, the concept of building a people-distribution scheme must be adapted to the existing, arbitrary grid of real places of a lecture hall, theater hall, cinema, or stadium. The article contains some practical examples with comments and an evaluation of benefits, both in terms of ensuring safety and in terms of effective use of space.
