An experimental device for evaluation of hydrogen sorption

Hydrogen storage for the purposes of the automotive industry in a form other than under high pressure or cryo conditions has been under careful investigation by researchers over past decades. One of the arising methods is the usage of powdered/granulated beds that contain metal hydrides and/or carbon materials to take advantage of the “spillover” phenomenon. Handling and characterization of such material can be troublesome, which is why the experimental setup needs careful investigation. The apparatus for the analysis of hydrogen sorption/desorption characteristics has been successfully designed and described based on the constructed unit within the scope of this article. The full functionality of that setup covered fuelling the bed as well as the examination of sorption/desorption potential. Moreover, the proposed experimental device can clarify many uncertainties about further development and optimization of hydrogen storage materials.

A Review of multi-modal speech emotion recognition and various techniques used to solve emotion recognition on speech data

Recognition of speech emotions is one of the emerging disciplines in artificial intelligence. It can make better decisions in a variety of industries, including healthcare, education, and marketing, by using speech emotion recognition technologies to help us grasp human emotions and behavior. Despite challenges, this task is crucial for Human-Computer Interaction (HCI). This study creates a strong and trustworthy emotion recognition system that can be employed in practical contexts as technology and scientific knowledge of emotions evolve. Many fields employ speech emotion recognition, though it does have limitations such as inter-subject variability, noise, ambient influences, over-fitting, and a lack of annotated data. The multi-modal format provides three different input modalities: audio, text, and video. With the aim of offering readers, a modern understanding of the popular field of research, the study rigorously identifies and synthesizes recent relevant literature connected to the numerous design components/methodologies of SER systems. The proposed model leverages information from the encoded data to forecast the sentiment of the retrieved text while it encodes information from audio, video, and text (happy, sad, angry, or neutral). The method helps to minimize computational complexity while attaining competitive results on all tasks.
Therapeutic foliage: A balanced dataset designed for automated identification of leaves of common medicinal plants

Leaf pattern recognition through automated methods has gained significant popularity in the field of computer vision in recent years as it plays crucial role in monitoring plant health. By effectively identifying leaf patterns, it becomes possible to prevent the unnecessary wastage of crop yield as leaves depict relevant information about plant health, making it a vital pursuit in agricultural research. Owing to the significance of this research area here, this study has designed a novel database namely, Therapeutic foliage by including healthy and diseased leaf samples belonging to four different types of commonly available plants namely, Ixora (West Indian Jasmine), Catharanthus roseus (Madagascar Periwinkle), Bougainvillea (Paper flower) and Epipremnum aureum (Devil's ivy) having immense medicinal properties. The newly developed database comprises of 1200 images of diseased and healthy leaves where 300 images of leaf samples are included from each type of plant. The images containing leaves included in this database possess complex backgrounds containing weeds and various other objects and are captured under varied illumination conditions using different camera angles. To the best of our knowledge, Therapeutic foliage is the first database which is designed by including leaves from these four species, none of the existing databases contain leaves of these plants. The effectiveness of this database is also validated in this work by performing classification using several deep neural networks like AlexNet, Vgg16, ResNet152, MobileNetv2, ShuffleNetv2, SqueezeNet, InceptionV3, InceptionResNetv2, DenseNet121, NasNetLarge, NasNetMobile, GhostNetv2, EfficientNetB7 and Xception. Out of all these networks, DenseNet121 has given the best results by registering an overall Test Accuracy of 99.5 % and giving impressing outputs for quantitative parameters like Recall, Precision and F1 score.
A pancreatic adenocarcinoma mimicking hepatoid carcinoma of uncertain histogenesis: A case report and literature review

In rare cases, metastatic adenocarcinomas of different origin may exhibit the features of hepatoid carcinoma (HC), a rare malignant epithelial tumor, most commonly occurring in the ovaries and stomach, as well as in the pancreas and biliary ducts. A case of a 72-year-old female patient who developed a highly aggressive, poorly differentiated pancreatic ductal adenocarcinoma with peritoneal carcinomatosis, demonstrating hepatoid differentiation upon conventional hematoxylin and eosin staining is reported in the present study. The patient presented with severe abdominal pain, and the radiological investigations performed revealed ovarian and hepatic tumor masses and peritoneal lesions, which were surgically removed. The gross examination of the peritoneum and omentum revealed multiple solid, firm, grey-white nodules, diffusely infiltrating the adipose tissue. The microscopic examination revealed a malignant epithelial proliferation, composed of polygonal cells with abundant eosinophilic cytoplasm and irregular, pleomorphic nuclei. Certain cells presented with intracytoplasmic mucus inclusions, raising suspicion of a HC with an uncertain histogenesis. Immunohistochemical staining was performed, and the tumor cells were found to be positive for cytokeratin (CK)7, CK18 and mucin 5AC, whereas negative staining for CK20, caudal-type homeobox transcription factor 2, α-fetoprotein, paired box gene 8, GATA-binding protein 3 and Wilms tumor 1 were documented. Thus, the diagnosis of metastatic pancreatic adenocarcinoma was established. The main aim of the present study was to provide further knowledge concerning poorly differentiated metastatic adenocarcinoma resembling HC, emphasizing the histopathological and immunohistochemical features of these malignant lesions and raising awareness of the diagnostic difficulties that may arise, as well as the importance of the use immunohistochemistry in differentiating carcinomas of uncertain histogenesis.

Reenement and Extension of Encrypted Key Exchange

In their recent paper, \Encrypted Key Exchange: Password-based Protocols Secure Against Dictionary Attacks ," Bellovin and Merritt propose a novel and elegant method for safeguarding weak passwords. This paper discusses a possible weakness in the proposed protocol, develops some enhancements and simpli-cations, and provides a security analysis of the resultant minimal EKE protocol. In addition, the basic 2-party EKE model is extended to the 3-party setting; this yields a protocol with some interesting properties. Most importantly, this paper illustrates, once again, the subtlety associated with designing password-based protocols.
Real-Time Computer-Aided Detection of Colorectal Neoplasia During Colonoscopy

BACKGROUND Artificial intelligence computer-aided detection (CADe) of colorectal neoplasia during colonoscopy may increase adenoma detection rates (ADRs) and reduce adenoma miss rates, but it may increase overdiagnosis and overtreatment of nonneoplastic polyps. PURPOSE To quantify the benefits and harms of CADe in randomized trials. DESIGN Systematic review and meta-analysis. (PROSPERO: CRD42022293181). DATA SOURCES Medline, Embase, and Scopus databases through February 2023. STUDY SELECTION Randomized trials comparing CADe-assisted with standard colonoscopy for polyp and cancer detection. DATA EXTRACTION Adenoma detection rate (proportion of patients with ≥1 adenoma), number of adenomas detected per colonoscopy, advanced adenoma (≥10 mm with high-grade dysplasia and villous histology), number of serrated lesions per colonoscopy, and adenoma miss rate were extracted as benefit outcomes. Number of polypectomies for nonneoplastic lesions and withdrawal time were extracted as harm outcomes. For each outcome, studies were pooled using a random-effects model. Certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework. DATA SYNTHESIS Twenty-one randomized trials on 18 232 patients were included. The ADR was higher in the CADe group than in the standard colonoscopy group (44.0% vs. 35.9%; relative risk, 1.24 [95% CI, 1.16 to 1.33]; low-certainty evidence), corresponding to a 55% (risk ratio, 0.45 [CI, 0.35 to 0.58]) relative reduction in miss rate (moderate-certainty evidence). More nonneoplastic polyps were removed in the CADe than the standard group (0.52 vs. 0.34 per colonoscopy; mean difference [MD], 0.18 polypectomy [CI, 0.11 to 0.26 polypectomy]; low-certainty evidence). Mean inspection time increased only marginally with CADe (MD, 0.47 minute [CI, 0.23 to 0.72 minute]; moderate-certainty evidence). LIMITATIONS This review focused on surrogates of patient-important outcomes. Most patients, however, may consider cancer incidence and cancer-related mortality important outcomes. The effect of CADe on such patient-important outcomes remains unclear. CONCLUSION The use of CADe for polyp detection during colonoscopy results in increased detection of adenomas but not advanced adenomas and in higher rates of unnecessary removal of nonneoplastic polyps.

Resultados: Os profissionais de engenharia treinam análise crítica e tomada de decisão, enquanto a máquina busca/processa informação e realiza simulações. Os cursos de graduação da EQ/Poli da UFRJ apresentam baixa evidência quanto à qualificação dos alunos em “inteligência emocional, tomada de decisão e relação com cliente”. Não foram identificadas evidências quanto à capacitação dos estudantes em “autogestão, empreendedorismo e conhecimento de modelo de negócios”.
Microcomputed tomography visualization and quantitation of the pulmonary arterial microvascular tree in mouse models of chronic lung disease

Abstract Pulmonary vascular dysfunction is characterized by remodeling and loss of microvessels in the lung and is a major manifestation of chronic lung diseases (CLD). In murine models of CLD, the small arterioles and capillaries are the first and most prevalent vessels that are affected by pruning and remodeling. Thus, visualization of the pulmonary arterial vasculature in three dimensions is essential to define pruning and remodeling both temporally and spatially and its role in the pathogenesis of CLD, aging, and tissue repair. To this end, we have developed a novel method to visualize and quantitate the murine pulmonary arterial circulation using microcomputed tomography (µCT) imaging. Using this perfusion technique, we can quantitate microvessels to approximately 6 µM in diameter. We hypothesize that bleomycin‐induced injury would have a significant impact on the arterial vascular structure. As proof of principle, we demonstrated that as a result of bleomycin‐induced injury at peak fibrosis, significant alterations in arterial vessel structure were visible in the three‐dimensional models as well as quantification. Thus, we have successfully developed a perfusion methodology and complementary analysis techniques, which allows for the reconstruction, visualization, and quantitation of the mouse pulmonary arterial microvasculature in three‐dimensions. This tool will further support the examination and understanding of angiogenesis during the development of CLD as well as repair following injury.
Optical absorption enhancement in inhomogeneous InGaN nanowire arrays photocathode

In the development of surface structures, nanowire arrays (NWAS) have been widely studied because of their trapping effect. In this paper, the finite difference time domain (FDTD) method is used to simulate homogeneous and inhomogeneous NWAS. We studied the influence of the structural parameters of InGaN NWAS and inhomogeneous arrays on optical response properties. The optical response includes light absorptivity and cutoff wavelength sensitivity. The simulation results show that the inhomogeneous NWAS can increase the effective transmission distance of light on the surface, thus greatly improving the optical absorption capacity of InGaN NWAS. We can obtain high sensitivity of cut-off wavelength by adjusting the structural parameters of the side nanowires. We find that by reducing the diameters and heights of the side nanowires, a higher light absorption rate can be obtained, which is a 5% improvement compared to uniform NWAS. Therefore, the research in this paper can provide some theoretical reference for the experiment and preparation of InGaN photocathodes.

Furthermore, their consumption-related attitude is affected by consumption-related cognition and values. Social structural variables (parental control, peer-group influ.
Epidemiology and Risk Factors for Stroke in Chronic Kidney Disease: A Narrative Review

Patients with chronic kidney disease (CKD) have a higher risk ofboth ischemic and hemorrhagic stroke. This association appears to be partly independent from the higher prevalence of established risk factors for stroke in patients with CKD, including hypertension and atrial fibrillation. In the present review we aim to discuss the impact of CKD on the risk of stroke and stroke-related consequences, and explore the pathophysiology underpinning the increased risk of stroke in patients with CKD. We cover the clinical association between renal dysfunction and cerebrovascular disease including stroke, silent brain infarct, cerebral small vessel disease, microbleeds, and white matter hyperintensity, and discuss the underlying mechanisms.
The Potential Use of THP-1, a Monocytic Leukemia Cell Line, to Predict Immune-Suppressive Potency of Human Bone-Marrow Stromal Cells (BMSCs) In Vitro: A Pilot Study

Adoptive transfer of cultured BMSCs was shown to be immune-suppressive in various inflammatory settings. Many factors play a role in the process, but no master regulator of BMSC-driven immunomodulation was identified. Consequently, an assay that might predict BMSC product efficacy is still unavailable. Below, we show that BMSC donor variability can be monitored by IL-10 production of monocytes/macrophages using THP-1 cells (immortalized monocytic leukemia cells) co-cultured with BMSCs. Using a mixed lymphocyte reaction (MLR) assay, we also compared the ability of the different donor BMSCs to suppress T-cell proliferation, another measure of their immune-suppressive ability. We found that the BMSCs from a donor that induced the most IL-10 production were also the most efficient in suppressing T-cell proliferation. Transcriptome studies showed that the most potent BMSC batch also had higher expression of several known key immunomodulatory molecules such as hepatocyte growth factor (HGF), PDL1, and numerous members of the PGE2 pathway, including PTGS1 and TLR4. Multiplex ELISA experiments revealed higher expression of HGF and IL6 by the most potent BMSC donor. Based on these findings, we propose that THP-1 cells may be used to assess BMSC immunosuppressive activity as a product characterization assay.
Gymnodinium catenatum GRAHAM: Aspect dynamique et toxicologique

La proliferation d'especes phytoplanctoniques a caractere toxique dans les eaux cotieres constitue une menace pour la sante publique et l'exploitation commerciale des mollusques. En 1994, un bloom de Gymnodinium catenatum sur les cotes atlantiques marocaines ayant provoque une forte contamination des moules par la PSP dont l’ingestion a cause l'intoxication de 78 personnes dont 4 deces. Depuis 1989, les cotes mediterraneennes marocaines sont affectees par la toxicite des mollusques bivalves. Les taux eleves de toxines PSP enregistres dans la region de Martil-Oued Laou a l’Ouest, dus a la proliferation frequente de G catenatum, sont a l'origine de l’interdiction a l'exploitation et a la commercialisation des coquillages. L’etude de la dynamique des populations de Gymnodinium catenatum est menee au niveau de la region de Tetouan zone d'apparition habituelle. L'analyse des donnees de la surveillance sur la periode 1994-2004 a permis d'identifier le schema de variabilite spatio-temporelle de cette espece en parallele avec Alexandrium spp. Dans le but d’etablir la relation entre les conditions environnementales et les blooms de G catenatum, des mesures journalieres ont ete prises durant les periodes d’efflorescences de G catenatum en janvier, mai, juillet et novembre 2001. Chaque saison, une croisiere de deux radiales perpendiculaires a la cote a ete menee jusqu’a 30m de profondeur. G. catenatum etait observe pendant les quatre saisons de l’annee, le bloom le plus important etait observe en Novembre. Les concentrations les plus importantes se situent entre 20 et 25m a 8 . 103cel. l-1 Le bloom s'est estompe au bout d’une semaine et l’assemblage phytoplanctonique etait domine par Noctiluca scintillans et Protoperidinium spp. La temperature de l'eau etait comprise entre 16 et 17°C et la salinite entre 35 et 36,7 PSU. Une correlation positive entre l'apparition des blooms de G. catenatum et le rapport N/P a ete etablie. L'etude de recherche des kystes de G catenatum a montre que la source la plus probable de contamination des coquillages reste les cellules vegetatives qui se developpent souvent dans les couches d'eau inferieures en dehors des periodes de blooms. Ceci a ete confirme par les analyses du profil toxinique effectuees au niveau du phytoplancton et des coques et vernis durant le bloom de G catenatum. Les periodes de risques pour la contamination des coquillages par la PSP due a l'espece G catenatum sont situees entre les mois de novembre et janvier. En dehors de cette periode il y a un risque moins important du a Alexandrium spp qui se situe de juillet a septembre.
EVALUATION OF DEXMEDETOMIDINE AS AN ADJUVANT TO ROPIVACAINE IN SUPRACLAVICULAR BLOCK FOR PATIENTS UNDERGOING UPPER LIMB PLASTIC SURGICAL PROCEDURES.

Background: Different adjuvants are used with local anesthetics to improve quality of peripheral nerve blocks. The aim of our study was to evaluate the effect of addition of dexmedetomidine with ropivacaine in supraclavicular brachial plexus block with respect to onset of sensory and motor blockade and duration of blockade and analgesia. Patients and Methods: Sixty patients of ASA grade I and II, aged 18-55 years of either sex scheduled for upper limb plastic surgical procedures under supraclavicular brachial plexus block were randomly divided into two equal groups. Patients in control group R (n = 30) received 29 ml of 0.5% and analgesic requirements. In our study we evaluated the effect of addition of dexmedetomidine (50mcg) to ropivacaine in supraclavicular block. Results of our study infer that onset of sensory & motor blockade were rapid with adding dexmedetomidine to ropivacaine. Our observations are in accordance with the findings of Esmaoglu A et al. [16] who evaluated the effect of dexmedetomidine added to levobupivacaine for brachial plexus block and observed that the onset of sensory & motor blockade was shorter (9.03±1.15 min ,9.50 ±1.04 min respectively ) in dexmedetomidine group than (10.46±1.30 min,11.10±1.24min respectively) in control Group. Similar findings were observed by Ammar and Mahmoud. [17] Our findings revealed that duration of sensory & motor blockade prolonged in group RD as compared to group R. This may be because peripheral alpha2 agonist produces analgesia by reducing the release of norepinephrine leading to alpha2 receptor independent inhibitory effects on nerve fiber action potential. Centrally, alpha2 agonist produces sedation and analgesia by abolition of Substance P release in nociceptive pathway at the level of dorsal horn and activation of alpha2 receptor in locus ceruleus. [18] Our observations were in accordance with the findings of Swami SS et al. [19] they used alpha2 agonist with local anaesthetic to extend the duration of peripheral nerve blocks. Ammar and Mahmoud [17] observed that adding dexmedetomidine (0.75mcg/kg) to bupivacaine (0.33 %) significantly prolonged the duration of sensory & motor blockade as compared to bupivacaine alone. compared observations in the findings Kathuria
