Establishment and application of TSDPSO-SVM model combined with multi-dimensional feature fusion method in the identification of fracture-related infection
Authors: Hu Xiaofeng , Chen Jianmin , Zheng Xiaofei , Li Jianmei , Zhou Mingwei
Published: November 2023

Fracture-related infection (FRI) is one of the most common and intractable complications in orthopedic trauma surgery. This complication can impose severe psychological burdens and socio-economic impacts on patients. Although the definition of FRI has been proposed recently by an expert group, the diagnostic criteria for FRI are not yet standardized. A total of 4761 FRI patients and 4761 fracture patients (Non-FRI) were included in the study. The feature set of patients included imaging characteristics, demographic information, clinical symptoms, microbiological findings, and serum inflammatory markers, which were reduced by the Principal Component Analysis. To optimize the Support Vector Machine (SVM) model, the Traction Switching Delay Particle Swarm Optimization (TSDPSO) algorithm, a recognition method was proposed. Moreover, five machine learning models, including TSDPSO-SVM, were employed to distinguish FRI from Non-FRI. The Area under the Curve of TSDPSO-SVM was 0.91, at least 5% higher than that of other models. Compared with the Random Forest, Backpropagation Neural Network (BP), SVM and eXtreme Gradient Boosting (XGBoost), TSDPSO-SVM demonstrated remarkable accuracy in the test set ($$\chi^{ 2} = 29.17, \,50.46, \,56.66,\,35.88, P < 0.01$$χ2=29.17,50.46,56.66,35.88,P<0.01). The recall of TSDPSO-SVM was 98.32%, indicating a significant improvement ($$\chi^{2} = 91.78,\, 107.42, \,135.69, P < 0.01$$χ2=91.78,107.42,135.69,P<0.01). Compared with BP and SVM, TSDPSO-SVM exhibited significantly superior specificity, false positive rate and precision ($$\chi^{2} > 3.84, P < 0.05)$$χ2>3.84,P<0.05). The five models yielded consistent results in the training and testing of FRI patients across different age groups. TSDPSO-SVM is validated to have the maximum overall prediction ability and can effectively distinguish between FRI and Non-FRI. For the early diagnosis of FRI, TSDPSO-SVM may provide a reference basis for clinicians, especially those with insufficient experience. These results also lay a foundation for the intelligent diagnosis of FRI. Furthermore, these findings exhibit the application potential of this model in the diagnosis and classification of other diseases.

Published: November 2023

Chromium is a hazardous compound from industrial processes, known for its toxicity, mutagenicity, teratogenicity, and carcinogenicity. Chemical methods are efficient but cost-effective alternatives with reduced sludge are sought. Electro-coagulation, utilizing low-cost iron plate electrodes, was explored for factual tannery wastewater treatment in this manuscript. Operating parameters such as initial chromium concentration, voltage, electrode number, operating time, agitation speed and current density has been studied to evaluate the treatment effeciency. Under optimal conditions (15 V, 0.4 mA/cm2, 200 rpm, 330 ppm chromium, 8 iron electrodes with a total surface area of 0.1188 m2, 3 h), chromium elimination was 98.76%. Iron anode consumption, power use, and operating cost were 0.99 gm/L, 0.0143 kW-h/L, and 160 EGP/kg of chromium eliminated, respectively. Kinetics studies were pursued first-order reaction (97.99% correlation), and Langmuir isotherms exhibited strong conformity (Langmuir R2: 99.99%). A predictive correlation for chromium elimination (R2: 97.97%) was developed via statistical regression. At HARBY TANNERY factory in Egypt, industrial sewage treatment achieved a final chromium disposal rate of 98.8% under optimized conditions.
Optically induced resonant tunneling of electrons in nanostructures
Authors: Boev M. V. , Kovalev V. M. , Kibis O. V.
Published: November 2023

We developed the theory of elastic electron tunneling through a potential barrier driven by a strong high-frequency electromagnetic field. It is demonstrated that the driven barrier can be considered as a stationary two-barrier potential which contains the quasi-stationary electron states confined between these two barriers. When the energy of an incident electron coincides with the energy of the quasi-stationary state, the driven barrier becomes fully transparent for the electron (the resonant tunneling). The developed theory is applied to describe electron transport through a quantum point contact irradiated by an electromagnetic wave.
Variations of intronic branchpoint motif: identification and functional implications in splicing and disease
Authors: Xie Jiuyong , Wang Lili , Lin Ren-Jang
Published: November 2023

The branchpoint (BP) motif is an essential intronic element for spliceosomal pre-mRNA splicing. In mammals, its sequence composition, distance to the downstream exon, and number of BPs per 3´ splice site are highly variable, unlike the GT/AG dinucleotides at the intron ends. These variations appear to provide evolutionary advantages for fostering alternative splicing, satisfying more diverse cellular contexts, and promoting resilience to genetic changes, thus contributing to an extra layer of complexity for gene regulation. Importantly, variants in the BP motif itself or in genes encoding BP-interacting factors cause human genetic diseases or cancers, highlighting the critical function of BP motif and the need to precisely identify functional BPs for faithful interpretation of their roles in splicing. In this perspective, we will succinctly summarize the major findings related to BP motif variations, discuss the relevant issues/challenges, and provide our insights.

Authors: Morya Sonia , Sandhu Deepika , Neumann Arno , James Simon Chacha
Published: November 2023

This chapter addresses sustainable environmental remediation by valorization of wastes and their by-products obtained from agro-food industries. The agro-food industry generates a huge amount of agro-food waste and by-products from fruit and vegetable processing which are well known for their excellent source of valuable constituents such as bioactives (secondary metabolites). The antioxidative, anti-carcinogenic, anti-inflammatory, anti-allergic, and anti-atherogenic properties of bioactive compounds have a very positive impact on health and are also known to modulate metabolic processes as well as help in cellular activities for human health, depending on the pathway and their bioavailability in the body. Consequently, this chapter highlights an overview of current trends and future prospects in the conversion of residues from various food sections into value-added products.

Authors: Zaimi Harith Syahmi , Amin Muhd Arshad , Shukor Hafiza , Shoparwe Noor Fazliani , Makhtar Muaz Mohd Zaini
Published: November 2023

Nowadays, the health and quality of life in the ecosystem are heavily influenced by waste quantities that are steadily increasing. Globally, the agro-industry produces valuable materials such as agri-food wastes with well-known potential. These wastes have natural bioactive compounds that can be used in various applications, especially in renewable energy or the so-called biofuel production. Biofuels, which are renewable and carbon-neutral, are being considered one of the possible solutions to reduce transportation emissions and human reliance on fossil fuels. Agricultural food wastes are promising feedstocks for the biofuel industry because they are produced in large quantities, are inedible, and are currently underutilized. The biotechnological approach in the bioconversion of agricultural food waste into biofuels will be a great strategy to improve their applicability in order to avoid environmental problems and could help the economy and society. In this chapter, these approaches are covered in detail as a valorization approach to these agricultural food waste for biofuel production. Regarding the production of bioethanol and biobutanol, mature biofuel biotechnologies will be discussed in this chapter. In addition, this chapter also provides recent trends and innovations in lignocellulosic agricultural food waste valorization treatment and hydrolysis in sustainable biofuel production. The current trends and challenges are also investigated, considering future perspectives. This strategy is consistent with the benefits of the circular economy model of reducing, reusing, and recycling, and it promotes the possibility of establishing and optimising new supply chains for biorefineries of agri-food wastes.

Inhibition of smooth muscle cell death by Angiotensin 1-7 protects against abdominal aortic aneurysm
Authors: Jadli Anshul S. , Gomes Karina P. , Ballasy Noura N. , Wijesuriya Tishani Methsala , Belke Darrell , Fedak Paul W.M. , Patel Vaibhav B.
Published: November 2023

Abdominal aortic aneurysm (AAA) represents a debilitating vascular disease characterized by aortic dilatation and wall rupture if it remains untreated. We aimed to determine the effects of Ang 1-7 in a murine model of AAA and to investigate the molecular mechanisms involved. Eight- to 10-week-old apolipoprotein E-deficient mice (ApoEKO) were infused with Ang II (1.44 mg/kg/day, s.c.) and treated with Ang 1-7 (0.576 mg/kg/day, i.p.). Echocardiographic and histological analyses showed abdominal aortic dilatation and extracellular matrix remodeling in Ang II-infused mice. Treatment with Ang 1-7 led to suppression of Ang II-induced aortic dilatation in the abdominal aorta. The immunofluorescence imaging exhibited reduced smooth muscle cell (SMC) density in the abdominal aorta. The abdominal aortic SMCs from ApoEKO mice exhibited markedly increased apoptosis in response to Ang II. Ang 1-7 attenuated cell death, as evident by increased SMC density in the aorta and reduced annexin V/propidium iodide-positive cells in flow cytometric analysis. Gene expression analysis for contractile and synthetic phenotypes of abdominal SMCs showed preservation of contractile phenotype by Ang 1-7 treatment. Molecular analyses identified increased mitochondrial fission, elevated cellular and mitochondrial reactive oxygen species (ROS) levels, and apoptosis-associated proteins, including cytochrome c, in Ang II-treated aortic SMCs. Ang 1-7 mitigated Ang II-induced mitochondrial fission, ROS generation, and levels of pro-apoptotic proteins, resulting in decreased cell death of aortic SMCs. These results highlight a critical vasculo-protective role of Ang 1-7 in a degenerative aortic disease; increased Ang 1-7 activity may provide a promising therapeutic strategy against the progression of AAA.

Authors: García-Cortijo María Carmen , Ferrer Juan R. , Castillo-Valero Juan Sebastián , Pinilla Vicente , Carrasco Inmaculada , Serrano Raúl
Published: November 2023

This study introduced the application of a new methodology to the assessment of sustainability for wineries in Spain. It adapted Rosen’s hedonic models, developed in other areas of the economy, to explain the environmental commitment of wineries in terms of trends in their attributes, considering: a) resources and capabilities; b) development variables; c) commercial factors. The database for the empirical analysis was drawn up from two surveys; the first was performed in 2016, and the second occurred between 2020 and 2021. Using the Box-Cox technique, the results showed that improving the companies' attributes, especially in human resources and management, exports and distribution via Horeca, promotes a greater valorization of sustainability by the wineries.

The effect of uniform blurring of images on their (statistical) radiomic features of the first order is studied. Two sets each consisting of 100 images with sizes of 100 by 100 and 700 by 700 are chosen as a dataset. Tables showing the effect of blurs on seventeen selected radiomic properties are given. The mean, variation and coefficient of variation of changes in the considered properties for various degrees of blurring are estimated. It is concluded that the most representative radiomic properties characterizing blurs are the mean, RMS and energy.

Now a days Both temporary and permanent disabilities affect a large number of people in this one of the disabilities is blindness there are a lot of blind persons in the world. Nearly 390 lakh individuals are fully blind, and another 2850 lakh are purblind, or visually impaired, according to the World Health Organisation (WHO). Many supporting or guiding systems have been established, and are still being developed, to improve people’s daily lives as they move from one place to another. Therefore, the main concept behind our suggested method is to provide an auto-assistance system for people who are visually impaired. As a result of their inability to see the object, the disabled person may find this auto-assistance system useful. To create an assisting system for blind persons, numerous methods have been put into place. Some systems are still being studied. The implemented models had a number of drawbacks when it came to object detection. We suggest a new method that uses CNNs (Convolutional Neural Networks) to aid those who are blind or visually impaired.

Finding the most unique traits that have strong discrimination capacities to be used for confirmation, in particular with reference to the substantial variation that’s intrinsic in real signatures, is among the main difficulties in developing an algorithm for electronic signature validation. Handwritten signs offer the potential for expertly made frauds that closely resemble genuine equivalents. During this work, we proposed a methodical approach for authenticating online signs via an MLP that relies on a predetermined set of PCA (principal component analysis) features. This suggested method demonstrates an attribute selection methodology using data obtained from PCA calculations that is often disregarded but may be important in achieving a lower error rate. Utilizing a 5000-sign sample from the SIGMA database, the study produced false rates of acceptance (FAR) and false rates of rejection of 17.4% and 16.4%, respectively.
Telecom Operators in Virtual Heterogeneous Networks May Benefit from Dynamic Resource Replacement for Virtual Services Based on Flow Splitting: FSB-DReViSeR
Authors: Gohatre Umakant Bhaskar , Patil Venkat P. , Chavan Sunil S.
Published: November 2023

Virtual networks provide their services by aggregating groups of virtual devices that use an existing physical network to interact with one another. These services, unlike the underlying network, often need a large number of distinct resources (bandwidth, processing power, servers, etc.) to operate. The adaptability of the virtual network architecture is what makes it so appealing. A server is required for each virtual service; hence computers are categorized as virtual service resources. It is common practice to either supply resources for the virtual network or replace the virtual service resource by migrating the service to another node that offers the most suitable number of resources to do so (QoS) when a given resource is unable to meet quality of service requirements due to traffic variation caused by mobile users. Our flow-splitting technique allows for the dynamic redistribution of virtual service resources across several virtual connections. We take a different approach than the prevalent tree-based approaches in the current body of literature by basing our method on graph topology instead. The simulation results from this study demonstrate that our solution drastically decreases the time needed to replace virtual service resources when compared to existing methods.

Published: November 2023

Les avortements constituent un enjeu majeur dans l’élevage équin, du fait de la perte économique importante engendrée dans les élevages et des conséquences sanitaires d’un éventuel phénomène infectieux. Le diagnostic étiologique doit donc être établi le plus précocement possible. Les causes des avortements peuvent être classées en trois catégories : infectieuses, non-infectieuses et indéterminées. En fonction des études, l’étiologie non-infectieuse représente entre 10 et 60 % des cas d’avortement. Parmi les causes non-infectieuses, on distingue les anomalies des annexes fœtales, avec les anomalies du cordon ombilical dont la torsion du cordon ombilical, et les anomalies du placenta comme les hypoplasies/aplasies/atrophies des villosités, les séparations prématurées du placenta ou les hydropisies des enveloppes fœtales ; les anomalies de gestation avec les gestations gémellaires et les gestations dans le corps placentaire ; les anomalies fœtales avec les malformations congénitales ; et les causes d’origine maternelle comme une maladie chronique, une intoxication ou des affections utérines (kystes utérins, lésions cicatricielles endométriales, adhérences, etc.). La torsion du cordon ombilical est la cause non-infectieuse d’avortement la plus fréquente avec une fréquence de 16,5 % du total des avortements et 60 % des avortements d’origine non-infectieuse en Normandie en 2011. Un cordon ombilical excessivement long est un facteur de risque pour les torsions.
Complications des chirurgies d’ostéosynthèse chez le cheval
Authors: Aimonetti Emma , Vercherin Anouk , Rossignol Fabrice
Published: November 2023

Les chirurgies d’ostéosynthèse par suite de fractures sont des chirurgies d’urgence. Que le pronostic sportif soit favorable ou que la procédure soit salvatrice et mette un terme à la carrière d’athlète du patient, ces procédures requièrent des connaissances anatomiques et techniques considérables. L’anticipation de leurs complications est possible dès la prise en charge du patient sur le terrain. La gestion de la douleur dans les phases pré- et postopératoires permet de prévenir la survenue de certaines complications.

L’infection du site chirurgical et la fourbure du membre controlatéral sont les complications graves les plus courantes.

La gestion de l’infection des implants implique le retrait de ces derniers, et diverses stratégies peuvent permettre de retarder cette échéance jusqu’à la cicatrisation de la fracture.

D’une manière générale en chirurgie d’ostéosynthèse, une complication infectieuse double le coût et divise le pronostic par deux.

Published: November 2023

Response and bifurcation of fractional Duffing oscillator under recycling noise and time-delayed feedback control are investigated. Firstly, based on the principle of the minimum mean square error and small time-delayed approximation and linearize the cubic stiffness term, the fractional derivative is equivalent to a linear combination of damping and restoring forces, and the original system is simplified into an equivalent integer order system. Secondly, the Itô differential equations and one-dimensional Markov process are obtained according to stochastic averaging method, and the stochastic stability and stochastic bifurcation of the system are analyzed. Lastly, through joint probability density function diagram and the stationary probability density function diagram, the stochastic bifurcation behavior of system under the different time-delay, fractional order and noise intensity are discussed respectively, the validity of the theory and the occurrence of bifurcation phenomenon are verified.

Einsamkeit: Aus der Isolation ins Vertrauen
Authors: Textor Reinhard
Published: November 2023

Einsamkeit betrifft laut Umfragen fast die Hälfte der Menschen, ist jedoch keine Diagnose, sondern ein subjektives Gefühl mit zum Teil hohem Leidensdruck und Risiken für weitere Erkrankungen. Man unterscheidet intime (Partnerschaft), soziale (Freunde, Bekannte) und kollektive (Gesellschaft) Einsamkeit. Im vorgestellten Fall konnte der Klient, der sich in der Kindheit in den Schutzraum der Nacht flüchtete und später fast komplett isolierte, die Therapiestunden als Übungsfeld nutzen, um wieder Vertrauen und Kontakt aufzubauen.

Purpose To utilize 4 D flow MRI to acquire normal values of “conventional 2 D flow MRI parameters” in healthy volunteers in order to replace multiple single 2 D flow measurements with a single 4 D flow acquisition.

Materials and Methods A kt-GRAPPA accelerated 4 D flow sequence was used. Flow volumes were assessed by forward (FFV), backward (BFV), and net flow volumes (NFV) [ml/heartbeat] and flow velocities by axial (VAX) and absolute velocity (VABS) [m/s] in 116 volunteers (58 females, 43 ± 13 years). The aortic regurgitant fraction (RF) was calculated.

Results The sex-neutral mean FFV, BFV, NFV, and RF in the ascending aorta were 93.5 ± 14.8, 3.6 ± 2.8, 89.9 ± 0.6 ml/heartbeat, and 3.9 ± 2.9 %, respectively. Significantly higher values were seen in males regarding FFV, BFV, NFV and RF, but there was no sex dependency regarding VAX and VABS. The mean maximum VAX was lower (1.01 ± 0.31 m/s) than VABS (1.23 ± 0.35 m/s). We were able to determine normal ranges for all intended parameters.

Conclusion This study provides quantitative 4 D flow-derived thoracic aortic normal values of 2 D flow parameters in healthy volunteers. FFV, BFV, NFV, and VAX did not differ significantly from single 2 D flow acquisitions and could therefore replace time-consuming multiple single 2 D flow acquisitions. VABS should not be used interchangeably.

Background Imaging biomarkers are quantitative parameters from imaging modalities, which are collected noninvasively, allow conclusions about physiological and pathophysiological processes, and may consist of single (monoparametric) or multiple parameters (bi- or multiparametric).

Method This review aims to present the state of the art for the quantification of multimodal and multiparametric imaging biomarkers. Here, the use of biomarkers using artificial intelligence will be addressed and the clinical application of imaging biomarkers in breast and prostate cancers will be explained. For the preparation of the review article, an extensive literature search was performed based on Pubmed, Web of Science and Google Scholar. The results were evaluated and discussed for consistency and generality.

Results and Conclusion Different imaging biomarkers (multiparametric) are quantified based on the use of complementary imaging modalities (multimodal) from radiology, nuclear medicine, or hybrid imaging. From these techniques, parameters are determined at the morphological (e. g., size), functional (e. g., vascularization or diffusion), metabolic (e. g., glucose metabolism), or molecular (e. g., expression of prostate specific membrane antigen, PSMA) level. The integration and weighting of imaging biomarkers are increasingly being performed with artificial intelligence, using machine learning algorithms. In this way, the clinical application of imaging biomarkers is increasing, as illustrated by the diagnosis of breast and prostate cancers.
