A NEW TRAVELLING WAVE SOLUTION OF THE MIKHAILOV-NOVIKOV-WANG SYSTEM USING THE EXTENDED TANH METHOD

In this paper, we consider the new fth-order integrable Mikhailov-Novikov-Wang (MNW) system. By using the extended tanh method, travelling wave solutions of the (MNW) system are presented. As a particular case, new exact solutions of the Kaup{Kupershmid (KK) are obtained.
Supersymmetric Yang-Mills theory at order α'3

We construct the order α' 3 terms in the supersymmetric Yang-Mills action in ten dimensions for an arbitrary gauge group. The result can be expressed in terms of the structure constants of the Yang-Mills group, and is therefore independent of abelian factors. The α' 3 invariant obtained here is independent of the α' 2 invariant, and we argue that additional superinvariants will occur at all odd orders of α'.
Effect of Dynamic Threshold-Voltage Instability on Dynamic ON-State Resistance in SiC MOSFETs

This work presents an investigation of several important phenomena related to threshold-voltage instability in SiC MOSFETs. Such instability can occur in previously unstressed as-processed devices, including trench-geometry devices, when exposed to a negative gate-bias overstress. This work also reports, for the first time for SiC MOSFETs, on the dynamic nature of ON resistance in the presence of large threshold-voltage instabilities, whether occurring in as-processed devices or due to an ac stress-induced degradation.
Power Optimization in Wireless Communication Systems

Mobile wireless communication is undoubtedly one of the main drivers of industrial development and economic growth in modern societies. Its ability to incorporate cutting-edge technologies and deliver the successful value proposition to end-users has made it an essential part of human lives. Regardless of the technology used, any system would like to achieve optimal interference management or maximize its efficiency. And interestingly, the underlying element that characterizes such parameters is the transmission power. From a network efficiency viewpoint or the quality services provided to the users, the transmission power plays an important role in achieving the optimality in either of the cases. With an objective to address the power optimization in wireless systems, in this thesis, different types of network architectures are considered, with an objective to improve the spectrum and energy efficiency. In particular, starting with the conventional multi-antenna system, this thesis addresses the long-standing problem of dependency on channel state information in network optimization. In doing so, a simple solution to introducing robustness in imperfect channel estimates based on classical transmit power minimization metric is considered. Furthermore, the energy efficiency issue in a hybrid network topology with the macro base station co-existing with small cell networks is also investigated. We show the key idea in achieving energy efficient network with a higher level of granularity is the strategical selection of base stations. With an insight into the millimeter wave systems, a lucrative solution in estimating channel parameters compared to the state-of-the-art is provided, thus reducing the energy cost at the transmitter and/or receiver. In addition, transmit power optimization in millimeter wave systems is also considered thereby revisiting the key transmission strategies with a low complexity analog and digital beamforming/precoding design.
MHC Class II Expression Influences the Composition and Distribution of Immune Cells in the Metastatic Colorectal Cancer Microenvironment

Simple Summary Extensive data exist regarding the importance of major histocompatibility complex (MHC) class I in the tumor microenvironment, but data on MHC class II (MHC-II) are lacking. Using multiplex immunohistochemistry and spatial modeling, we demonstrate that MHC-II expression impacts both the relationships of cells traditionally associated with T lymphocyte priming and spatial interactions of cytotoxic lymphocytes and tumor cells in colorectal cancer. Abstract Despite advances in therapy over the past decades, metastatic colorectal cancer (mCRC) remains a highly morbid disease. While the impact of MHC-I on immune infiltration in mCRC has been well studied, data on the consequences of MHC-II loss are lacking. Multiplex fluorescent immunohistochemistry (mfIHC) was performed on 149 patients undergoing curative intent resection for mCRC and stratified into high and low human leukocyte antigen isotype DR (HLA-DR) expressing tumors. Intratumoral HLA-DR expression was found in stromal bands, and its expression level was associated with different infiltrating immune cell makeup and distribution. Low HLA-DR expression was associated with increased intercellular distances and decreased population mixing of T helper cells and antigen-presenting cells (APC), suggestive of decreased interactions. This was associated with less co-localization of tumor cells and cytotoxic T lymphocytes (CTLs), which tended to be in a less activated state as determined by Ki67 and granzyme B expression. These findings suggest that low HLA-DR in the tumor microenvironment of mCRC may reflect a state of poor helper T-cell interactions with APCs and CTL-mediated anti-tumor activity. Efforts to restore/enhance MHC-II presentation may be a useful strategy to enhance checkpoint inhibition therapy in the future.
Modelos computacionales en la posturografía

Objetivo: Realizar la clasificación y el mapeo de parámetros de balanceo corporal a partir de datos de posturografía estática para diferenciar individuos amputados transtibiales unilaterales de no amputados utilizando técnicas de aprendizaje automático y minería de datos. Metodología: El balanceo corporal se midió en 74 individuos, 37 amputados por mina antipersonal y 37 controles sanos. Se clasificó la estabilidad según el grupo haciendo uso de aprendizaje automático. Se desarrolló un mapa bidimensional continuo de las alteraciones de la postura utilizando la teoría de la información de Shannon, la prueba de U Mann-Whitney(p<0.05) fue usada con el fin de identificar diferencias entre grupos. Resultados: Se entrenaron cinco algoritmos de aprendizaje automático, un árbol de decisión, reglas de decisión, una red neuronal, una máquina de soporte vectorial y el clúster. La validación y la comparación se llevaron a cabo con las métricas obtenidas a partir de la matriz de confusión, utilizando validación cruzada para obtener dos subconjuntos. La condición de postura más discriminativa se clasificó como desplazamiento del centro de presión (CoP) lado no amputado dirección antero-posterior. El algoritmo de mayor desempeño fue la máquina de soporte vectorial y el de menor desempeño el clúster, sin embargo, todos los modelos realizaron clasificación de grupos con una puntuación F1 mayor a 0,4. Conclusiones: El mapeo de las características del desplazamiento del balanceo en el espacio 2D reveló agrupaciones claras entre amputados y controles, lo cual confirma que el aprendizaje automático puede ayudar en la clasificación de patrones de balanceo clínico medidos con posturografía estática. Los modelos computacionales permiten evaluar de forma objetiva la estabilidad, así como reconocer el aporte de contralateral en el control de la postura bípeda estática ya que compensa la no existencia de los aferentes y eferentes de ipsilateral. Financiamiento: Artículo de investigación científica derivado del proyecto de investigación “Caracterización de la Estabilidad en Amputados Transtibiales Unilaterales”, financiado por la Universidad Distrital Francisco José de Caldas, Bogotá, Colombia.
Crystallization of Amorphous In2O3 Films during Film Growth

The effect of the film thickness on crystallization of amorphous indium oxide films was investigated using transmission electron microscopy and electron diffraction. Films of different thicknesses, 10-60 A, were reactively evaporated on SiO substrates at 200°C. The results showed that the amorphous films crystallized markedly with increasing film thickness above 40 A, while below the thickness of 40 A, the films partially crystallized from pre-existing crystallites. Concurrently, the microstructure of the films became almost continuous above the thickness of 40 A.
Garlic as active principle of sanitiser for hatching eggs

SUMMARY Scientific advances are one of the reasons why natural sanitisers are sought after for use in poultry farming, of which garlic-based sanitiser is one. Therefore, this work provides a brief review of garlic’s potential in sanitising hatching eggs. There are no reports of negative effects of garlic on the microbiological quality of the eggshell nor the main incubation evaluation parameter (hatchability). On the contrary, garlic in low concentrations has improved the number of chicks produced (higher hatchability) through reducing eggshell contamination. More studies are needed to support the complete effectiveness and optimise and further encourage the application of this compound in poultry farming.
Can the Part Replace the Whole? A Choice Experiment on Organic and Pesticide-Free Labels

Chemical pesticides are a serious impediment to agricultural sustainability. A large-scale reduction in their use to secure food supplies requires more innovative and flexible production systems. Pesticide-free production standards bring together the strengths of all participants in the food value chain and could be the catalyst for this transition. Using a choice experiment approach and green tea as an example, this study investigated consumers’ preferences for organic and pesticide-free labels. According to the findings, organic and pesticide-free labels and brands are all major factors that affect consumers’ purchase decisions. Consumers are more willing to pay for organic labels than pesticide-free labels. There is a substitution effect between organic labels and pesticide-free labels. Complementary effects exist between organic labels and national brands, pesticide-free labels, and national brands. Consumer trust has an impact on consumers’ choice of organic labels and pesticide-free labels. The use of pesticide-free labels is an alternate approach for small- and medium-sized businesses in a specific market to lower the cost of organic certification.
A review of component-in-the-loop: Cyber-physical experiments for rapid system development and integration

To meet rising demands in performance and emissions compliance, companies are driven to develop systems of ever-increasing complexity. In-the-loop methods use a hybrid approach combining a physical subsystem with a virtual subsystem in real-time that can make product development processes faster and cheaper, enabling physical subsystems to be tested in real-world conditions while they are immersed in virtual environment simulation. These techniques evolved from being used solely in controller development with only the embedded controller placed as hardware-in-the-loop (HIL), to being a more holistic technique for system synthesis, capable of both component- and system-level studies. This paper delves into the development of the latter form, henceforth referred to as ‘component-in-the-loop’ or CIL. It provides a literature review of the growing uses of the technique in automotive development, giving a general implementation guidance in system architecture, methodology and control system structure. Furthermore, it suggests the need to clarify terminologies related to in-the-loop methods for a more efficient taxonomy. Definitions are proposed where deemed appropriate. In the age of search engines, this should facilitate knowledge transfer within and across disciplines. Finally, it highlights the key challenges in constructing such systems while discussing attempted solutions. CIL has reached a state of maturity where it is ready for wider adoption and continued technological progress will only push its potential further.
Functionality and Performance of the Subretinal Implant Chip Alpha AMS

Electronic retinal implants have been developed and are marketed as a therapeutic option for blind people suffering from degenerative retinal diseases such as retinitis pigmentosa. The functionality of subretinal implants depends heavily on the performance of the electronic interface to the retina. For the RETINA IMPLANT Alpha AMS device, this interface consists of a subretinally implanted chip that samples the retinal image, like a camera chip, and stimulates the adjacent retina simultaneously at the corresponding locations. The technical functionality of the RETINA IMPLANT Alpha AMS is described and compared with the outcome of two clinical trials over an observation period of one year. The discrimination of different grey levels observed in these clinical trials confirms that the sensitivity of the implanted CMOS chip can be varied over the range of relevant light intensities. We show that accelerated aging lifetime measurements of implant components in a laboratory environment match implant lifetimes observed during clinical trials for the predecessor device, the RETINA IMPLANT Alpha IMS. By using the same model for the current technically advanced device, the RETINA IMPLANT Alpha AMS, the predicted clinical lifetime of the implant is about 5 years.
Vonoprazan - a new drug for inhibiting gastric acid secretion

Introduction and purpose Vonoprazan is a potassium-competent acid blocker (P-CAB). It has the potential to be an alternative to proton pump inhibitors (PPIs) as it inhibits hydrochloric acid secretion. The mechanism of action is different than PPIs - vonoprazan reversibly inhibits gastric H+, K+-ATPase, while PPIs irreversibly. Vonoprazan is approved for use in Japan and the US. The aim of the study was to review articles on the use of vonoprazan instead of PPIs in the treatment of acid-related gastrological diseases and to present the results obtained. A brief description of the state of knowledge Vonoprazan is used in the treatment of acid-related gastrological diseases. The 20 mg dose is suitable for most diseases, such as treatment of ulcers during low-dose aspirin treatment, post-endoscopic submucosal dissection (post-ESD) ulcers, erosive esophagitis (EE) in gastroesophageal reflux disease (GERD), and Helicobacter pylori eradication. Summary Researches suggest that the drug is an alternative for PPIs and can be used instead of them. The main advantage of this drug over PPIs is that it works faster, more potent and long-lasting. Studies suggest that vonoprazan can be use to treatment of the acid-related diseases and may be a better choice than PPIs. Vonoprazan may have a particular use in the treatment of PPI-refractory GERD. In post-ESD ulcers, a significant benefit in treatment effects of vonoprazan over PPIs cannot be clearly concluded.
Nano-Ag Particles Embedded in C-Matrix: Preparation, Properties and Application in Cell Metabolism

The application of nano-Ag grains as antiviral and antibacterial materials is widely known since ancient times. The problem is the toxicity of the bulk or big-size grain materials. It is known that nano-sized silver grains affect human and animal cells in some medical treatments. The aim of this study is to investigate the influence of nano-Ag grains embedded in a carbonaceous matrix on cytotoxicity, genotoxicity in fibroblasts, and mutagenicity. The nanocomposite film is composed of silver nanograins embedded in a carbonaceous matrix and it was obtained via the PVD method by deposition from two separated sources of fullerenes and silver acetate powders. This method allows for the preparation of material in the form of a film or powder, in which Ag nanograins are stabilized by a carbon network. The structure and morphology of this material were studied using SEM/EDX, XRD, and Raman spectroscopy. The toxicology studies were performed for various types of the material differing in the size of Ag nanograins. Furthermore, it was found that these properties, such as cell viability, genotoxicity, and mutagenicity, depend on Ag grain size.
Multidrug-Resistant Biofilm, Quorum Sensing, Quorum Quenching, and Antibacterial Activities of Indole Derivatives as Potential Eradication Approaches

Challenges encountered in relapse of illness caused by resistance of microorganisms to antimicrobial agents (drugs) are due to factors of severe stress initiated by random use of antibiotics and insufficient beneficial approaches. These challenges have resulted to multiple drug resistance (MDR) and, subsequently, biofilm formation. A type of intercellular communication signal called quorum sensing (QS) has been studied to cause the spread of resistance, thereby enabling a formation of stable community for microorganisms. The QS could be inhibited using QS inhibitors (QSIs) called quorum-quenching (QQ). The QQ is an antibiofilm agent. Indole derivatives from plant sources can serve as quorum-quenching eradication approach for biofilm, as well as a promising nontoxic antibiofilm agent. In other words, phytochemicals in plants help to control and prevent biofilm formation. It could be recommended that combination strategies of these indoles' derivatives with antibiotics would yield enhanced results.
Sex Disparity in Cause-Specific and All-Cause Mortality Among Incident Dialysis Patients.

RATIONALE & OBJECTIVE Early mortality rates of female patients on dialysis have been, at times, observed to be higher than rates among male patients. The differences in cause-specific mortality between male and female incident dialysis patients with kidney failure are not well understood and were the focus of this study. STUDY DESIGN Retrospective cohort study. SETTING & Participants: Incident patients who had initiated dialysis in Australia and New Zealand between 1998-2018. EXPOSURE Sex. OUTCOMES Cause-specific and all-cause mortality on dialysis, censored for kidney transplantation. ANALYTICAL METHODS Adjusted cause-specific proportional hazards models, focusing on the first 5 years following initiation of dialysis. RESULTS Among 53,414 patients (20,876 [39%] of whom were female) followed for a median period of 2.8 (IQR 1.3-5.2) years, 27,137 (51%) died, with the predominant cause of death attributed to cardiovascular disease (CVD, 18%), followed by dialysis withdrawal (16%). Compared to male patients, female patients were more likely to die in the first 5 years after dialysis initiation (adjusted hazard ratio (aHR) of 1.06 [95% CI 1.03-1.09]). Even though female patients experienced a lower risk of CVD-related mortality (aHR 0.93 [0.89-0.98]) compared to male patients, they experienced a greater risk of infection-related (aHR 1.20 [1.10-1.32]) and dialysis withdrawal-related mortality (aHR 1.19 [1.13-1.26]). LIMITATIONS Possibility of residual and unmeasured confounders. CONCLUSION Compared with male patients, female patients had a higher risk of all-cause mortality in the first 5 years post-dialysis initiation, a difference driven by higher mortality from infections and dialysis withdrawals. These findings may inform the study of sex differences in mortality in other geographic settings.
Genetic Diversity, Analysis of Some Agro-Morphological and Quality Traits and Utilization of Plant Resources of Alfalfa

Alfalfa (Medicago sativa L.) is one of the most important perennial forage crops to build effective diets for livestock producers. Forage crop improvement depends largely on the availability of diverse germplasms and their efficient utilization. The present investigation was conducted at Ismailia Agricultural Research Station to assess twenty-one alfalfa genotypes for yield components, forage yield and quality traits during 2019/2020 and 2020/2021. The genotypes were evaluated in field experiments with three replicates and a randomized complete block design, using analysis of variance, estimate of genetic variability, estimate of broad sense heritability (hb2) and cluster analysis to identify the inter relationships among the studied genotypes as well as principal component analysis (PCA) to explain the majority of the total variation. Significant differences were found among genotypes for all studied traits. The general mean of the studied traits was higher in the second year than the first year. Moreover, the combined analysis showed highly significant differences between the two years, genotypes and the year × gen. interaction for the traits studied. The genotype F18 recorded the highest values for plant height, number of tiller/m2, total fresh yield and total dry yield, while, the genotype F49 ranked first for leaf/stem ratio. The results showed highly significant variation among the studied genotypes for crude protein %, crude fiber % and ash %. Data revealed that the genotypes P13 and P5 showed the highest values for crude protein %, whereas, the genotype F18 recorded the highest values for crude fiber % and ash content. The results revealed high estimates of genotypic coefficient and phenotypic coefficient of variation (GCV% and PCV%) with high hb2, indicating the presence of genetic variability and effective potential selection for these traits. The cluster analysis exhibited considerable genetic diversity among the genotypes, which classified the twenty one genotypes of alfalfa into five sub-clusters. The genotypes F18, F49, K75, S35, P20, P5 and P13 recorded the highest values for all studied traits compared with other clusters. Furthermore, the PC analysis grouped the studied genotypes into groups and remained scattered in all four quadrants based on all studied traits. Ultimately, superior genotypes were identified can be utilized for crop improvement in future breeding schemes.
Modelling and Investigation of Energy Harvesting System Utilizing Magnetically Levitated Permanent Magnet

The aim of this article is mathematical modelling and investigation of chosen parameters of a small energy harvesting system designed for energy harvesting from car tire mechanical vibrations to provide power supply for various sensors, e.g., in tire pressure monitoring system. The energy harvester consists of three permanent magnets inserted into a tube made from polyamide material. Comsol program has been used to calculate the force between the magnets, the stiffness of the magnetic spring, and the natural frequency of the system. MATLAB program has been used to simulate the movement of the moveable magnet to compare it with the measurements. Finally, the parameters of the mathematical model of the energy harvester were investigated and validated on a specially prepared laboratory test bench.
