Authors: Fayad Mohammed A. , Alani Waleed K. , Dhahad Hayder A. , Zheng Jing
Published: April 2023

In this study, the impact of butanol-diesel blends and exhaust gas recirculation (EGR) on engine performance, NOX emissions, smoke, and particulate matter (PM) characteristics were experimentally investigated under fuel post-injection condition. The maximum peak of cylinder pressure is achieved under without EGR compared with applied different rates of EGR. Furthermore, the brake thermal efficiency (BTE) increased during the combustion of B20 and B10 by 4.25% and 2.61%, respectively, compared with diesel fuel combustion. Considerable reductions in carbonaceous gas emissions (CO and THC) and nitrogen oxides (NOX) were achieved from combustion of B20 and B10 compared to the diesel fuel for with and without EGR. The NOX emissions decreased with 30% of EGR compared with 15% of EGR for all fuels studied. The results indicated that the addition butanol to the diesel fuel significantly reduced smoke opacity and soot emissions by 31.3% and 35.26%, respectively, compared with diesel. It is observed that an effective reduction of the NOX emissions to be higher during the combustion of B20 compared to the combustion of B10 and diesel for different EGR rates. The results of PM emission showed increase by 16% under 15% of EGR and 28% under 30% of EGR compared to the without EGR for all fuels tested. The number, concentration and size of PM decreased from combustion of B20 and B10 compared with diesel fuel combustion for with and without EGR.

We use observations with the infrared-optimized Magellan Adaptive Optics (MagAO) system and Clio camera in 3.9 μm light to place stringent mass constraints on possible undetected companions to Sirius A. We suppress the light from Sirius A by imaging it through a grating vector-apodizing phase plate coronagraph with a 180° dark region (gvAPP-180). To remove residual starlight in postprocessing, we apply a time-domain principal-components-analysis-based algorithm we call PCA-Temporal, which uses eigen time series rather than eigenimages to subtract starlight. By casting the problem in terms of eigen time series, we reduce the computational cost of postprocessing the data, enabling the use of the fully sampled data set for improved contrast at small separations. We also discuss the impact of retaining fine temporal sampling of the data on final contrast limits. We achieve postprocessed contrast limits of 1.5 × 10−6–9.8 × 10−6 outside of 0.″75, which correspond to planet masses of 2.6–8.0 M
J. These are combined with values from the recent literature of high-contrast imaging observations of Sirius to synthesize an overall completeness fraction as a function of mass and separation. After synthesizing these recent studies and our results, the final completeness analysis rules out 99% of ≥9 M
J planets from 2.5 to 7 au.
Notes on mammals collected on the 1885 Geographical Society of Australasia’s Expedition to New Guinea
Authors: Parnaby Harry E. , Dwyer Peter D. , Helgen Kristofer M.
Published: April 2023

In 1885 the Geographical Society of Australasia sent the steam launch Bonito to chart the Fly and Strickland Rivers (now in Western Province, Papua New Guinea). The Expedition spent five months in New Guinea with the primary objectives of survey and biological exploration. The type locality of the murid rodent Melomys muscalis froggatti Troughton, 1937, described from a single specimen obtained during the Expedition, is localized to the region of the base camp at Observation Bend, Strickland River, based on the original Expedition maps and the unpublished diary reminiscence of the collector W. W. Froggatt. A review of the mammal collection obtained during that Expedition has not been reported previously, perhaps due to the poor surviving documentation. Several months after the Expedition returned to Sydney, Australian Museum curator E. P. Ramsay prepared a list of 22 mammal specimens received by the Museum. Twenty specimens attributed to the Expedition were not entered into the collection registers until 1913, half of which are likely to be incorrectly associated with the Expedition. Most specimens were registered with very limited data about collection date and locality. Of the 22 specimens originally received by Ramsay, eight rodents and two flying foxes (Pteropus spp.) have not been located in the Collection, but might remain unrecognized as specimens with no data. It is possible that additional mammal specimens were sent by the Geographical Society of Australasia to other institutions at the conclusion of the Expedition.

Optimal investment and reinsurance for the insurer and reinsurer with the joint exponential utility under the CEV model
Authors: Chen Ling , Hu Xiang , Chen Mi
Published: April 2023

This paper considers the problem of optimal investment-reinsurance for the insurer and reinsurer under the constant elasticity of variance (CEV) model. It is assumed that the net claims process is approximated by a diffusion process, both the insurer and reinsurer can invest in risk-free assets and risky assets. We use the variance premium principle to calculate the premiums of the insurer and reinsurer, and the reinsurance proportion is constrained by the net profit condition. Our objective is to maximize the joint exponential utility of the insurer and reinsurer's terminal wealth for a fixed time. By solving the HJB equation, we obtain the explicit expressions of the optimal investment-reinsurance strategy and value function. We find that the optimal reinsurance strategy can be divided into many cases and is related to the risk aversion coefficient of the insurer and reinsurer, but independent of the price of risky assets. Furthermore, we give the proof of the verification theorem. Finally, we demonstrate a numerical analysis to explain the results.

Published: April 2023

In 2022, breast cancer will become an important factor affecting women's public health and HER2 positivity for approximately 15–20$ \% $ invasive breast cancer cases. Follow-up data for HER2-positive patients are rare, and research on prognosis and auxiliary diagnosis is still limited. In light of the findings obtained from the analysis of clinical features, we have developed a novel multiple instance learning (MIL) fusion model that integrates hematoxylin-eosin (HE) pathological images and clinical features to accurately predict the prognostic risk of patients. Specifically, we segmented the HE pathology images of patients into patches, clustered them by K-means, aggregated them into a bag feature-level representation through graph attention networks (GATs) and multihead attention networks, and fused them with clinical features to predict the prognosis of patients. We divided West China Hospital (WCH) patients (n = 1069) into a training cohort and internal validation cohort and used The Cancer Genome Atlas (TCGA) patients (n = 160) as an external test cohort. The 3-fold average C-index of the proposed OS-based model was 0.668, the C-index of the WCH test set was 0.765, and the C-index of the TCGA independent test set was 0.726. By plotting the Kaplan-Meier curve, the fusion feature (P = 0.034) model distinguished high- and low-risk groups more accurately than clinical features (P = 0.19). The MIL model can directly analyze a large number of unlabeled pathological images, and the multimodal model is more accurate than the unimodal models in predicting Her2-positive breast cancer prognosis based on large amounts of data.

Published: April 2023

In the realm of robotics and interactive systems, gender recognition is a crucial problem. Considering the several uses it has in security, web search, human-computer interactions, etc., gender recognition from facial photos has garnered a lot of attention. The need to use and enhance gender recognition techniques is felt more strongly today due to a significant development in the design of facial recognition systems. Relatively speaking to other approaches, the progress gained in this area thus far is not exceptional. Thus, a novel method has been adopted in this study to improve accuracy in comparison to earlier research. To create the best rate of accuracy and efficiency in the suggested method of this research, we choose a minimal set of characteristics. Testing on the FERET and UTK-Face datasets reveals that our suggested algorithm has a lower degree of inaccuracy. In this article, the input image of the person's face is pre-processed to extract the right features from the face once the person's face has been recognized. Gender separation is achieved using Multi-class Support Vector Machine (SVM) Classifiers after features from normalized images have been extracted using Histogram Oriented Gradient (HOG), Gabor Filters, and Speeded Up Robust Features (SURF), as well as their combination to select the most appropriate feature from them as input for gender classification. As a feature reduction feature, the Principal Component Analysis (PCA) algorithm is also employed. Using the proposed approach, 98.75% gender recognition precision has been accomplished on the FERET database and a runtime performance of 0.4 Sec. on the UTK-Face database, 97.43% gender recognition accuracy has been accomplished and a runtime performance of 0.5 Sec.
Trust and Voice Biometrics Authentication for Internet of Things
Authors: Wells Alec , Usman Aminu Bello
Published: April 2023

In recent years, IoT adoption has been higher, and this causes lots of security concerns. One of the fundamental security concerns in IoT adoption is the question, “Are you who you say you are?” Thus, authentication forms the gateway for a secure communication system with IoT. So far, the human voice is one of the most natural, non-intrusive, and convenient behavioural biometric factors compared to other biometric authentication methods. Despite the non-intrusive characteristics of voice as a biometric authentication factor when accessing IoT technologies, there is a concern of a general societal trust and distrust with IoT technology and the risk of theft of users' data and imitation. This study derived a realistic trust evaluation model that incorporates privacy, reliability, security, usability, safety, and availability factors into a trust vector for a flexible measurement of trust in the user accessing IoT technologies.
Fabric Blockchain Design Based on Improved SM2 Algorithm
Authors: Fu Jinhua , Zhou Wenhui , Zhang Suzhi
Published: April 2023

As one of the most widely used federated chains, hyperledger fabric uses many cryptographic algorithms to ensure the security of information on the chain, but the ECDSA cryptographic algorithm used in the fabric system has backdoor security risks. In this paper, the authors adopt SM2 algorithm to replace the corresponding ECDSA algorithm for blockchain design based on fabric platform. Firstly, they optimize the part of SM2 signature algorithm process with inverse operation and effectively reduce the time complexity by reducing the inverse operation in the whole process, and the experimental results show that the improved SM2 algorithm improves the signature and verification efficiency by about 5.7%. Secondly, by adding SM2 algorithm template and interface to the BCCSP module of fabric platform to realize the shift value of SM2 algorithm and compare the performance with the native fabric system, the network startup time is reduced by about 29%. The experimental results show the effectiveness of the improved SM2 algorithm, and also the performance of the optimized fabric system is improved.

Published: April 2023

The details of immune molecules' expression in desmoid tumors (DTs) remain unclear. This study aimed to determine the expression status of the programmed death-1/programmed death ligand 1 (PD1/PD-L1) immune checkpoint mechanism in DTs. The study included patients with DTs (n=9) treated at our institution between April 2006 and December 2012. Immunostaining for CD4, CD8, PD-1, PD-L1, interleukin-2 (IL-2), and interferon-gamma (IFN-γ) was performed on pathological specimens harvested during the biopsy. The positivity rate of each immune component was calculated as the number of positive cells/total cells. The positivity rate was quantified and correlations between the positivity rates of each immune molecule were also investigated. Immune molecules other than PD-1 were stained in tumor cells and intra-tumor infiltrating lymphocytes. The mean ± SD expression rates of β-catenin, CD4, CD8, PD-1, PD-L1, IL-2, and IFN-ɤ were 43.9±18.9, 14.6±6.80, 0.75±4.70, 0±0, 5.1±6.73, 8.75±6.38, and 7.03±12.1, respectively. The correlation between β-catenin and CD4 was positively moderate (r=0.49); β-catenin and PD-L1, positively weak (r=0.25); CD4 and PD-L1, positively medium (r=0.36); CD8 and IL-2, positively medium (r=0.38); CD8 and IFN-ɤ, positively weak (r=0.28); and IL-2 and IFN-ɤ, positively medium (r=0.36). Our findings suggest that PD-L1-centered immune checkpoint mechanisms may be involved in the tumor microenvironment of DTs.

Oral metastatic clear-cell tumours
Authors: Sharma Preeti , Wadhwan Vijay , Singh Roli
Published: April 2023

We report two extremely rare cases of metastatic clear-cell carcinomas, which metastasized from and to the oral cavity and both presented clinically in the oral cavity. First case was a primary lesion in the oral cavity, which showed distant metastatic deposits in liver, kidney, bone and brain. Histopathologically, lobules of pleomorphic clear cells were evident descending from the overlying mucosa, raising the suspicion of renal cell carcinoma. Immunohistochemical staining for CD10 was negative and the case was diagnosed as clear-cell type of oral squamous cell carcinoma which had disseminated to distant organs. In the second case, dysplastic clear granular cells were seen invading the bone. Immunohistochemical staining for CD10 showed focal mild positivity, confirming the diagnosis as clear-cell renal carcinoma which had metastasized to the oral cavity. Metastatic tumours must be considered in the differential diagnosis of rapidly growing ulcero proliferative lesions in the oral cavity.
Rational Prescribing and Deprescribing of Antihypertensive Medications in Older People, a Three-Part Narrative Review, Part 3
Authors: Russell Patrick , Thompson Campbell , Mangoni Arduino A.
Published: April 2023

What happens when you stop? This is the third of a three-part series on antihypertensive medication use in older people. In the first, we reviewed the importance of better blood pressure (BP) control, even in older people with hypertension. In the second, we discussed the limitations of the evidence favoring intensive therapy for some older people. For older people with advanced frailty or those with a limited life expectancy, medications taken for BP can actually be a source of morbidity. Guidelines encourage clinical judgment and rational prescribing. Sometimes the best action is to stop prescribing. De-prescribing of medical therapy is now considered good practice for a range of medications for suitable patients; should this include antihypertensives? In part three of this three-part series, we will review some of the evidence available thus far, demonstrating de-intensification of antihypertensive medications is not a new idea. We will offer a guide to identifying the most suitable patients for de-prescribing: cognitive impairment, frailty, when circumstances change, or when BP is (too) well-controlled. This is an area of equipoise and needs more research. There is a path forward that we hope to illuminate.

Finding the Causes of the Concretion Between Asthma and Urticaria: A Narrative Review
Authors: Ahmed Mahedi Md Rezwan
Published: April 2023

In recent years, asthma and urticaria have become more common globally, imposing a significant economic and health burden on communities everywhere. Th2 cells, mast cells, eosinophil and M2 macrophages are all part of type-2 immune response, which is characteristic of many forms of allergy and asthma. Biomarkers are essential for precision medicine because of the clarity they provide in the identification of disease endotype, clusters, specific diagnoses, therapeutic target selection and the tracking of therapy effectiveness. Accurately measuring the biomarkers requires a variety of tools, including dependable point-of-care systems. It is preferable to collect samples in a way that is both quick and non-intrusive. In recent years, researchers have placed a premium on identifying novel biomarkers of allergic diseases and asthma. There are a number of intriguing markers of urticaria and asthma, including eosinophils, immunoglobulin E (IgE), interleukin and vitamin D insufficiency. The latest findings on the biomarkers associated with asthma and chronic urticaria are summarised in this article.
Management of Splenic Injury in Blunt Abdominal Trauma- A Cross-Sectional Study
Authors: Goel Rishabh
Published: April 2023

Background: Spleen is the most commonly injured solid organ following blunt trauma. Motor vehicle collision account for more than 75% of splenic injuries. In up to 60% of patients, the spleen is the only organ injured, with mortality rates of roughly 8.5%. Some studies quote that more than half of blunt splenic injuries can be managed by non-operative management with morbidity similar to or less than that of operative management. The management of blunt splenic trauma has therefore shifted towards non operative management.

Objective: To study the management of splenic injury in blunt abdominal trauma.

Material and Methods: A Cross-sectional study was conducted in the department of Surgery, Rohilkhand Medical College and Hospital, Bareilly from 1st November 2020 to 31st October 2021. 36 patients of splenic trauma were included in the study.

Result: All grade I and II and 7 out of 10 grade III splenic injuries were managed conservatively. Three patients with grade III splenic damage underwent surgical intervention, with one undergoing splenectomy and two undergoing splenorrhaphy. In Grade IV splenic damage, 6 out of 7 patients were managed operatively, splenectomies were performed in 5 patients and splenorrhaphy was performed in 1 patient. All patients with grade V injuries underwent a splenectomy.

Conclusion: In our study, patients with Grade I and Grade II splenic trauma and the majority of Grade III trauma a total of 52.5% of patients could be managed conservatively.

Published: April 2023

Background: The precise treatment of ventral hernias is still a topic of considerable debate. The aim of this study was to compare the methods of open retromuscular sublay versus laparoscopic intraperitoneal onlay mesh repair for ventral hernias.

Methods: Following approval by the Institutional Ethics Committee, Rohilkhand Medical College and Hospital, Bareilly, 88 patients were randomly divided into two groups in 1:1 allocation ratio, each compromising 44 patients. Patients characteristics, hernia size and postoperative complications were recorded.

Results: Mean operative time was significantly (p= <0.001) lower in the SUBLAY group (55.66±8.34 minutes) than in the IPOM group (68.75±10.44 minutes). The post-operative pain(VAS) was significantly (p=0.001) lower amongst patients of the IPOM group (2.36±0.61) as compared to the sublay (4.52±0.66) group. The hospital stay was significantly (p=0.001) lower among patients of the IPOM group (3.61±2.28 days) than the sublay group (6.50±1.68 days).

Conclusion: Laparoscopic repair in medium- and large-sized defects is a feasible and safe approach. IPOM compared to SUBLAY significantly reduces postoperative complications and hospital stay.

Published: April 2023

A pesar de que la agenda política actual explicita la importancia de generar procesos de transferencia, son pocas las evidencias sobre el impacto directo de los resultados obtenidos en proyectos I+D+I en el diseño de políticas educativas, más allá de recomendaciones. Se desconoce en gran medida su aplicabilidad en la mejora de los procesos educativos e institucionales y, más concretamente, en modelos formativos concretos. El artículo somete a revisión sistemática la producción científica derivada de un proyecto nacional de investigación sobre la institucionalización de la educación inclusiva en la universidad con el objeto de transferir dicho conocimiento con consistencia y rigor. Se analizaron un total de 26 producciones científicas que dan cuenta del discurso de los actores de la universidad y de los resultados de proyectos piloto aplicados en distintas áreas de institucionalización. En dicha producción se señala la formación docente como motor de cambio y avance hacia la inclusión en la institución. A diferencia de la tradicional transmisión de conocimientos científicos en el campo de las ciencias de la educación, este trabajo aporta como novedad un modelo aplicable en la formación del profesorado universitario como ejercicio de transferencia con implicaciones para las prácticas y las políticas universitarias. Al mismo tiempo, este modelo se contextualiza con el estudio de la oferta formativa sobre la educación inclusiva en las universidades españolas, en el que se evidencia su estado incipiente de institucionalización como línea estratégica y con una visión parcelaria de determinados rasgos de diversidad en los planes de formación docente.

Published: April 2023

It has developed into a new branch of medicine where doctors and researchers are continually working on numerous issues linked to lung ailments. This field of medicine studies lung abnormalities through chest pictures and classifies them using artificial intelligence and machine learning techniques. As graphics drives and data storage systems have gotten more prevalent and sophisticated, enormous amounts of medical picture data are now being produced. Despite the fact that there have been several studies in the medical profession over the past ten years, this particular area has not received enough attention because of a lack of data. Numerous researchers have employed custom feature learning algorithms, but the results have not been sufficiently useful for real-world applications. The employed technique is advantageous in bridging the semantic gap between low-stage records obtained by imaging tools and high-stage information preserved by living things. With five layers—a convolutional layer, an activation layer, a pooling layer, an absolutely linked layer, and a softmax layer—that decide the output probability for each component, we created a far better convolutional neural network that enables accurate X-ray image type. We built our model utilizing a set of facts that are freely accessible. To be honest, our version performs a respectable job at diagnosing conditions related to the chest. Comparative observations show that the proposed model is more suited for the class of chest-related problems.

Published: April 2023

Utilizing supplementary information in simple random sampling, this research paper discussed a new method for finding the finite population mean of a predictive variable, and the properties of the suggested method have been investigated. The suggested estimator’s advantages over traditional estimators are demonstrated using theoretical asymptotic techniques and empirical analysis. The recommended estimator outperforms the customary unbiased, ratio, product, and regression estimators, as well as many other known population mean estimators.

Published: April 2023

An effective human-computer interaction for collaborative, collective and brilliant computing is provided by the Gesture recognition. Our study uses a single 3-axis accelerometer and 3-axis gyroscope for acquiring the data. Dynamic Time Warping (DTW), time and frequency domain and gesture discrepancy features are extracted from the raw data and these features are subjected to supervised machine learning algorithms such as KNN, SVM, RF and ANN. The system is evaluated depending on the data base of more than 10,000 traces obtained from five subsets. Through this study, we intend to identify eating and drinking gestures and more broadly short activities on real time environment. Many approaches for gesture recognition in specific settings have already been explored and studied using the combined interaction of several sensors. Despite these powerful hypotheses, gesture interpretation is still fragile and often depends on the individual’s positioning relative to the cameras not with the sensors.
Liver transplantation for hepatocellular carcinoma
Authors: Taimr Pavel
Published: April 2023

Summary: The number of liver transplants for the indication of hepatocellular carcinoma is increasing. We consider the so-called Milan criteria, based on the number and size of the tumour, to be the basic indication framework. However, the original criteria are too restrictive – they prevent access to transplantation for a number of patients who would otherwise be suitable candidates for transplantation. There is therefore an effort to somehow expand these criteria. Decision-making is also burdened by a possible error in imaging – our knowledge of the dimensions and number of nodules is not accurate before transplantation. Later, factors reflecting the biological properties of the tumour were added and it was possible to select patients for transplantation with greater precision. Examples here include the use of alpha-fetoprotein, histological grading, microinvasion into vessels, etc. Also, the response of the tumour to treatment before transplantation can be an important indicator – the effect of locoregional (RFA, MWA, TACE) or even systemic treatment. The importance of pre-transplant administration of immunomodulatory treatment is not yet known. In larger transplant centres, the concept of their own criteria, established on the basis of their own data unique to a given centre, is already beginning to be promoted. The advantage is that it reflects local and specific conditions of the centre. Key words: liver transplantation – hepatocellular carcinoma – Milan criteria – IKEM criteria
International experience with Crohn’s disease exclusion diet (CDED) with partial enteral nutrition (PEN)
Authors: El-Lababidi Nabil
Published: April 2023

The role of dietary intervention in the induction of remission of Crohn’s disease (CD) has been confirmed again by the recent ECCO (European Crohn’s and Colitis Organization) and ESPGHAN (European Society for Paediatric Gastroenterology, Hepatology and Nutrition) guidelines. Exclusive enteral nutrition (EEN) should be the method of choice in induction of remission of active luminal CD in children. Steroids should be reserved for situations when intolerance or infectivity of EEN is present. The main limitations of EEN consist of its monotony and palatability. In search for a safe and at least similarly effective diet, Crohn’s disease exclusion diet (CDED) was developed. The number of published data regarding its safety and efficacy has increased significantly since the publication of the first randomized controlled trial in 2019. CDED seems, to be safe and its efficacy is very promising. It seems that CDED could be used in three scenarios: as a monotherapy, as a part of complex treatment and as rescue therapy in cases of loss of response. The use of CDED is promising but further research for evaluation of its efficacy, including the necessity of using partial enteral nutrition, on larger patient cohorts is required.

Published: April 2023

Fetching recently published research papers is a time consuming and tedious process for young researchers and even for experts. In real time searching papers based on keywords and queries in search engines may not result apt or proper research papers that the user searched for. Because these research papers lack proper links and citations that help to find the most concerned papers. To overcome this problem a hybrid model is proposed with time constraint that combines the Text mining and Recommendation algorithm. The preference of papers and articles are jointly modeled with matrices sharing common dimensions of researchers and papers. The initial process starts with text mining algorithm that matches keywords with the data available in web pages. The post process consists of recommendation algorithms with latent matrix factorization and tensor matrix with similar preferences in a dimensional space. This paper explains the hybrid experimental model that helps users to fetch the most recent and relevant paper in a short period of time

Published: April 2023

The ordinary least square (OLS) estimator is the Best Linear Unbiased Estimator (BLUE) when all linear regression model assumptions are valid. The OLS estimator, however, becomes inefficient in the presence of multicollinearity. Various one and two-parameter estimators have been proposed to circumvent the problem of multicollinearity. This paper presents a new twoparameter estimator called Liu-Kibria Lukman Estimator (LKL) estimator. The proposed estimator is compared theoretically and through Monte Carlo simulation with existing estimators such as the ordinary least square, ordinary ridge regression, Liu, Kibria-Lukman, and Modified Ridge estimators. The results show that the proposed estimator performs better than existing estimators considered in this study under some conditions, using the mean square error criterion. A real-life application to Portland cement and Longley datasets supported the theoretical and simulation results by giving the smallest mean square error compared to the existing estimators.
