DSA-Net: Infrared and Visible Image Fusion via Dual-stream Asymmetric Network
Authors: Yin Ruyi , Yang Bin , Huang Zuyan , Zhang Xiaozhi
Published: July 2023

Infrared and visible image fusion technologies are used to characterize the same scene by diverse modalities. However, most existing deep learning-based fusion methods are designed as symmetric networks, which ignore the differences between modal images and lead to the source image information loss during feature extraction. In this paper, we propose a new fusion framework for the different characteristics of infrared and visible images. Specifically, we design a dual-stream asymmetric network with two different feature extraction networks to extract infrared and visible feature maps respectively. The transformer architecture is introduced in the infrared feature extraction branch, which can force the network to focus on the local features of infrared images while still obtaining their contextual information. And the visible feature extraction branch uses residual dense blocks to fully extract the rich background and texture detail information of visible images. In this way, it can provide better infrared targets and visible details for the fused image. Experimental results on multiple datasets indicate that DSA-Net outperforms state-of-the-art methods in both qualitative and quantitative evaluations. In addition, we also apply the fusion results to the target detection task, which indirectly demonstrates the fusion performances of our method.
A Review of Brain Tumor Diagnosis and Segmentation
Authors: Kaifi Reham
Published: July 2023

Uncontrolled and fast cell proliferation is the cause of brain tumors. Early cancer detection is vitally important in order to save many lives. Brain tumors can be divided into several categories depending on the kind, place of origin, pace of development, and stage of progression; as a result, tumor classification is crucial for targeted therapy. The aim of brain tumor segmentation is to accurately delineate the areas of the brain. A specialist with a thorough understanding of brain illnesses must manually identify the proper type of brain tumor. Additionally, processing a lot of images takes time and is tiresome. Therefore, automatic segmentation and classification techniques are required to speed up and enhance the diagnosis of brain tumors. Tumors can be quickly and safely detected by brain scans using imaging modalities, including computed tomography (CT), magnetic resonance imaging (MRI), and others. Machine learning (ML) and artificial intelligence (AI) have shown promise in the development of algorithms that aid in automatic classification and segmentation utilizing various imaging modalities. This review discussed various types of brain tumors, publicly accessible datasets, enhancement methods, segmentation, feature extraction, classification, machine learning techniques, and deep learning, learning through transfer, for the study of brain tumors.
Solid Precipitation and Visibility Measurements at the Centre for Atmospheric Research Experiment (CARE) Site in Southern Ontario, Canada
Authors: Boudala Faisal S. , Milbrandt Jason A.
Published: July 2023

Accurate measurement of solid precipitation (S) has a critical importance for proper understanding of the Earth’s hydrological cycle, validation of emerging technologies and weather prediction models, and developing parameterizations of severe weather elements such as visibility (Vis). However, measuring S is still a challenging problem mainly because of wind effects. The wind effects are normally mitigated by using a Double-Fence Automated Reference (DFAR) system to reduce the wind speed (Ug). To contribute towards addressing some of these issues we have analyzed data sets collected at a site located in Southern Ontario, Canada using several instruments. The instruments include two Geonor gauges, one placed inside a DFAR (SDFAR) and the other inside a double Alter shield (DASG), a Pluvio2 gauge inside a single Alter shield (SASP), a HotPlate, a PARSIVEL2 Disdrometer that measures S and fall velocity (V), and a FD12P senor that measures S and type and Vis. The results show that for the Ug observed in this study (Ug < 6 ms-1), both DASG and SASP have similar collection efficiency (CE) of near 70%. The transfer functions (TF) for DASG and SASP as a function of Ug and also Ug, and V have been derived. The TF for the DASG that includes both Ug and V showed better agreement with observation than just Ug alone. The S measured using all the other instruments were correlated well with SDFAR, but the PARSIVEL2 and FD12P overestimated and underestimated the snow amount respectively as compared the SDFAR. However, the HotPlate captured similar amount of S as the SDFAR. According to this study, the SDFAR showed good correlation with Vis.
Experimental One Side Choppers Relating Neuro-Muscular Human Abilities to Heart Rates and Technological Evolution
Authors: Parra Igor , Morales Maria Luisa , Mar Francisco Javier , Carbonell Eudald
Published: July 2023

The length of time it takes to experimentally make one-sided choppers, as found in the fossil record, bears a linear relationship to the knapping process of fabricating them. In addition, this temporal frame appears to be related to human heart rates measured as beats per minute, which act as a physiological metronome. We achieved these observations assuming that any paleolithic one-sided chopper has the information needed to estimate quantitatively the number of strikes on it. The experimental data allow us to establish the total timing needed for the standard fabricating of any one-sided chopper. We discuss issues derived from these experimental results, showing the evolution of human neurological abilities from 2.4 million years ago to the Modern period through the duration of time needed for making one chopper to that needed to play a 19th-century music score on a piano. Given that the neuronal and physiological distance between both actions differs by a factor of 6, we propose the concept of “technome” to measure human evolution by using methodological homogeneous metrics applied to these two human technologic objects, the chopper and the piano.

Authors: Mansour Mohamed , Martens Jan , Blankenbach Jörg
Published: July 2023

Building Information Modelling (BIM) has gained significant relevance in civil engineering, particularly in the infrastructure sector. It offers the potential to increase efficiencies, optimize processes, and enhance sustainability throughout infrastructure projects’ life cycles. BIM consolidates information about asset components into a single model, enabling real-time updates, cost reduction, and improved consistency. Digital twins serve as valuable extensions of BIM in infrastructure, playing a crucial role during operation. By capturing real-time data from sensors and IoT devices, digital twins enabls continuous monitoring, proactive maintenance, efficient energy management, and informed decision-making for optimized operational efficiency. Advancements in 3D point cloud technologies, such as 3D laser scanning, have expanded BIM’s application in operation and maintenance. These technologies rapidly capture accurate and detailed three-dimensional information, prompting the exploration of automated alternatives to manual point cloud modeling. This paper demonstrates the application of supervised machine learning, specifically support vector machines, for analyzing and segmenting 3D point clouds, a crucial step in 3D modeling. Various approaches for semantic segmentation are introduced, investigated, and evaluated using diverse data sets. The results highlight the effectiveness of supervised machine learning techniques in achieving accurate segmentation of 3D point clouds.
Biofilm of Helicobacter pylori: Life Cycle, Features, and Treatment Options
Authors: Elshenawi Yasmine , Hu Shuai , Hathroubi Skander
Published: July 2023

Helicobacter pylori is a gastric pathogen that infects nearly half of the global population and is recognized as a group 1 carcinogen by the Word Health Organization. The global rise in antibiotic resistance has increased clinical challenges in treating H. pylori infections. Biofilm growth has been proposed to contribute to H. pylori’s chronic colonization of the host stomach, treatment failures, and the eventual development of gastric diseases. Several components of H. pylori have been identified to promote biofilm growth, and several of these may also facilitate antibiotic tolerance, including the extracellular matrix, outer membrane proteins, the coccoid morphology, modulated metabolism, efflux pumps, and virulence factors. Recent developments in therapeutic approaches targeting H. pylori biofilm have shown that synthetic compounds, such as small molecule drugs and plant-derived compounds, are effective at eradicating H. pylori biofilms. These combined topics highlight the necessity for biofilm-based research in H. pylori, to improve current H. pylori targeted therapeutic approaches and alleviate relative public health burden. In this review we discuss recent discoveries that have decoded the life cycle of H. pylori biofilms and current biofilm targeted treatment strategies.

Published: July 2023

The aim of the present study was to investigate whether chronic undernutrition modifies the response to rostafuroxin in juvenile rats. Chronic undernutrition was induced in male rats using a multideficient diet known as Regional Basic Diet (RBD), mimicking alimentary habits in impoverished regions worldwide. Animals were given RBD – or a control/CTRL normal diet for rodents – from weaning to 90 days, and rostafuroxin (1 mg/kg body mass) or vehicle were orally administered during the last 30 days. Undernourished rats became hypertensive at 55–60 days of age (tail-cuff recording). During the last two days, the rats were hosted in metabolic cages to measure food/energy, water, Na+ ingestion, and urinary volume. Blood and kidneys were collected after euthanasia. Rostafuroxin increased food/energy and Na+ intake in CTRL and RBD rats but had opposite effects on Na+ balance (intake minus urinary excretion): negative in CTRL and positive in RBD. The drug normalized the decreased plasma Na+ concentration found in RBD rats, increased urinary volume in RBD but not in CTRL, and decreased and increased urinary Na+ concentration in the RBD and CTRL groups, respectively. Rostafuroxin decreased the ouabain-sensitive (Na++K+)ATPase and increased the ouabain-resistant, furosemide-sensitive Na+-ATPase from proximal tubule cells in both groups, and normalized the systolic blood pressure in RBD without effect in CTRL rats. We conclude that chronic undernutrition modifies the response of blood pressure, caloric metabolism, Na+ distribution in liquid compartments, mobilization of Na+ from non-osmotic compartments, Na+ and water balance, and activity of renal Na+-transporting ATPases to rostafuroxin.

Predictability: The Missing Variable in Public Relations
Authors: Wilbur Douglas S.
Published: July 2023

This study offers an initial and exploratory examination of the role that the variable of predictability plays in crisis management. Leveraging the situational crisis communication theory, it employed two separate but inter-related experiments. They examined how manipulations of the level of crisis predictability impacted a number of crucial variables important for crisis response. The findings strongly indicate that when a crisis is framed as having been predictable, it results in a host of negative consequences for the involved organizations and complicates the recovery process. When a crisis is framed as having been unpredictable, it results in positive benefits for the organizations involved. This study provides justification for future research exploring the role of predictability during a crisis.
QuickDASH and PRWE Are Not Optimal Patient-Reported Outcome Measures After Distal Radial Fracture Due to Ceiling Effect
Authors: Bell Katrina R. , Oliver William M. , White Timothy O. , Molyneux Samuel G. , Clement Nicholas D. , Duckworth Andrew D.
Published: July 2023

Background:

The aim of this study was to determine the floor and ceiling effects for both the QuickDASH (shortened version of the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire) and the PRWE (Patient-Rated Wrist Evaluation) following a distal radial fracture (DRF). Secondary aims were to determine the degree to which patients with a floor or ceiling effect felt that their wrist was “normal” according to the Normal Wrist Score (NWS) and if there were patient factors associated with achieving a floor or ceiling effect.

Methods:

A retrospective cohort study of patients in whom a DRF was managed at the study center during a single year was undertaken. Outcome measures included the QuickDASH, PRWE, EuroQol-5 Dimensions-3 Levels (EQ-5D-3L), and NWS.

Results:

There were 526 patients with a mean age of 65 years (range, 20 to 95 years), and 421 (80%) were female. Most patients were managed nonsurgically (73%, n = 385). The mean follow-up was 4.8 years (range, 4.3 to 5.5 years). A ceiling effect was observed for both the QuickDASH (22.3% of patients with the best possible score) and the PRWE (28.5%). When defined as a score that differed from the best available score by less than the minimum clinically important difference (MCID) for the scoring system, the ceiling effect increased to 62.8% for the QuickDASH and 60% for the PRWE. Patients who had a ceiling score on the QuickDASH and the PWRE had a median NWS of 96 and 98, respectively, and those who had a score within 1 MCID of the ceiling score reported a median NWS of 91 and 92, respectively. On logistic regression analysis, a dominant-hand injury and better health-related quality of life were the factors associated with both QuickDASH and PRWE ceiling scores (all p < 0.05).

Conclusions:

The QuickDASH and PRWE demonstrate ceiling effects when used to assess the outcome of DRF management. Some patients achieving ceiling scores did not consider their wrist to be “normal.” Future research on patient-reported outcome assessment tools for DRFs should aim to limit the ceiling effect, especially for individuals or groups that are more likely to achieve a ceiling score.

Abstract: Background: Coronary collateral circulation (CCC) is a network of anastomosing channels, established by heart in response to ischemia of myocardium. Hypertension, diabetes mellitus, and BMI are well established risk factors for development of poor CCC. Good CCC minimizes symptoms of angina, reduce the size of infarcts and prevent adverse cardiac events. The current research study was designed to find out the association of visceral adiposity and development of CCC among patients with coronary artery disease. Materials and Methods: The prospective study, conducted in Civil Hospital Karachi, comprised of 270 patients of coronary artery disease. According to the Rentrop Cohen categorization, patients were placed into two groups: the group with good collateral circulation having Rentrop grades i2-3 (n = 140) and the group with poor collateral circulation having Rentrop grades i0-1(n = 130). Rentrop score was determined by angiography. Segmental multi-frequency bioelectrical impedance analyzer was used to determine body fat mass and body muscle mass. Using Omron body fat and weight measurement systems, visceral fat index (VFI) was evaluated to determine the composition of visceral adipose tissue. SPSS was used for data analysis (Version 22). To assess the independent risk factor for poor CCC, logistic regression analysis was used. ROC curve was constructed to assess the efficacy of VFI in identifying CCC. Results: Overall, good collateral circulations were observed in 51.9% (n=140) of CAD patients, whereas poor collateral circulations were ound in 48.1% (n=130) of patients. Poor CCC was significantly associated with hypertension (OR=3, 95%CI= 0.111-8.231, p = .001) and VFI (OR=2, 95%CI= 1.451-3.567, p =.001). ROC analysis revealed a VFI > 9 to be a potential predictor of poor CCC with AUC=0.9, sensitivity of 95.00% and specificity of 86%. Conclusion: The current study concluded that greater VFI and concomitant hypertension considerably increase the likelihood of having poor CCC, therefore, visceral adiposity can be considered as a potential target for preventing poor collateral circulation in patients with established cardiac disease.

Objetivo. Medir el acceso a través de la intermitencia en el suministro de agua potable en hogares mexicanos. Material y métodos. A través de la Encuesta Nacional de Salud y Nutrición 2022 (Ensanut 2022), se recolectó información sobre intermitencia en días por semana y horas por día durante las últimas cuatro semanas y el suministro de agua durante el año para la temporada de mayor escasez. Resultados. 31.5% de los hogares recibieron agua los siete días de la semana, las 24 horas del día. De estos, 17.4% no tuvo escasez en los últimos 12 meses. La intermitencia es más común entre hogares de las regiones en el sur del país y entre los más pobres. El 81% de las familias almacena agua y 16% almacena en contenedores portátiles como cubetas. Conclusión. En este artículo se presentan por primera vez patrones de intermitencia en el suministro de agua a nivel nacional en México. La gran mayoría de las familias no reciben agua de forma continua y tienen que almacenar agua. El almacenamiento podría disminuir la calidad del agua y la falta de confianza para su consumo con consecuencias para la salud. La conexión al sistema potable no refleja el acceso real de las familias al agua.

Published: July 2023

StayGold is an exceptionally bright and stable fluorescent protein that is highly resistant to photobleaching. Despite favourable fluorescence properties, use of StayGold as a fluorescent tag is limited because it forms a natural dimer. Here we describe the 1.6 Å structure of StayGold and generate a new derivative (mStayGold) that retains the brightness and photostability of the original protein while being fully monomeric.
Influence of mining activities on hydrological processes in Pingshuo mining district, Loess Plateau: Insights from spatio-temporal variations of δD and δ18O

Published: July 2023

Under the influence of mining activities, investigating hydrological processes is an important cornerstone of water resources and eco-environment protection. In this study, the stables isotopic compositions (δD and δ18O) of surface water and groundwater in five periods were analyzed to identify the formation and evolution of surface water and groundwater in mining district. The δD and δ18O indicate that the water bodies in the study area is mainly recharged by local precipitation and undergo evaporation. There is a close hydraulic connection between surface water, mine water and groundwater, the deep confined water is affected by the surface water and phreatic water due to the developing water-conducting fractures. The recharge of deep groundwater to the overlying aquifer may increase resulting in gradually obvious “oxygen drift” with the continuous development of fractures, which will decrease the degree of “oxygen drift” as the fractures reclogged. The δ18O of phreatic water in each period is depleted in southeast and enriched in northwest of the study area. The δ18O of confined water has an obvious spatial variation in the wet season due to the combined effects of the opencast working and underground mining, and a uniform spatial variation in the dry season. The difference in spatial variation of δ18O between phreatic and confined water may attribute to the regeneration rate, and the stable isotopic compositions in phreatic water is easier to recover than that of confined water after mining disturbance. This finding provides important information about hydrological characteristics of Pingshuo mining district.

Published: July 2023

In recent years, sustainability has been one of the topics of major concern in technological progress, and reducing energy consumption is one of the biggest challenges. The refrigeration industry is responsible for about 20% of the overall electricity used worldwide. The miniaturization, mass reduction and increased rotation speeds lead to higher shear rates. In turn, at these levels, many oils may exhibit non-Newtonian behaviors. The ability to assess non-Newtonian effects can help in choosing and developing more efficient lubricants, where even small increases in efficiency can represent significant energy savings. Thus, this paper investigates the effects of using different non-Newtonian oils in a typical journal bearing of a household refrigerator compressor. For this purpose, a thermo-hydrodynamic model was proposed where the modified Reynolds equation for fluids obeying the power law coupled with the energy equation are solved using the finite volume method in an iterative process. The cavitation boundary is calculated using the equation of conservation of mass and updated at each iteration. The parameters of the power law curve fitting were obtained from experimental data fitting. The results obtained show that even for small deviations from Newtonian behavior, significant variations in load capacity and friction force can be observed. Under the same operating conditions, the load capacity and friction force are 67% and 64%, respectively, lower for the bearing operating with an alkylbenzene oil than with a polyolester oil, while the consistency parameter at To(m0) is 90% lower.

Published: July 2023

Soft fingers with variable stiffness based on jamming principle have the characteristics of simple structure, convenient control, and rapid response, but is usually requires vacuum pressure to squeeze the particles or layered materials to produce stiffness changes. A novel passive variable stiffness soft finger based on the passive layer jamming principle was presented in this paper. The inflation chamber of the soft finger was bent and squeezes the outer wall of the jamming chamber. The squeezing force causes the jamming layer unit inside the jamming chamber to squeeze each other to generate friction, which causes stiffness changed. Besides, aiming at the previous manufacturing methods of double-chamber soft fingers, this work also proposes an “integrated molding” casting process based on the lost-wax casting method, which can realize the manufacturing of soft fingers through on casting without splice. The experimental results shown that the soft finger with passive layer jamming also has excellent grasping performance under the condition of reducing additional equipment (vacuum system).

Background: Researches have found that alteration of intestinal flora may be closely related to the development of autism spectrum disorder (ASD). However, whether probiotics supplementation has a protective effect on ASD remains controversial. This meta-analysis aimed to analyze the outcome of probiotics in the treatment of ASD children.
Methods: The Pubmed, Cochrane Library, Web of Science and Embase were searched until Sep 2022. Randomized controlled trials (RCTs) relevant to the probiotics and placebo treatment on ASD children were screened. Quality assessment of the included RCTs was evaluated by the Cochrane collaboration’s tool. The primary outcomes were ASD assessment scales, including ABC (aberrant behavior checklist) and CBCL (child behavior checklist) for evaluating the behavior improvement, SRS (social responsiveness scale) for social assessment, DQ (developmental quotient) for physical and mental development and CGI-I (clinical global impression improvement) for overall improvement. The secondary outcome was total 6-GSI (gastrointestinal severity index).
Results: In total, 6 RCTs from 6 studies with 302 children were included in the systemic review. Total 6-GSI (MD=-0.59, 95%CI [-1.02,-0.17], P<0.05) decreased significantly after oral administration of probiotics. Whereas, there was no statistical difference in ABC, CBCL, SRS, DQ and CGI-I between probiotics and placebo groups in ASD children.
Conclusion: Probiotics treatment could improve gastrointestinal symptoms, but there was no significant improvement in ASD.
How does technological innovation affect the ecological footprint? Evidence from E-7 countriesin the background of the SDGs
Authors: Dam Mehmet Metin , KAYA Funda
Published: July 2023

This research aimed to investigated relationship among technological innovation (TI), renewable energy consumption (REC), natural resource rents (NRR), and ecological footprint (EF) of E-7 (i.e., Brazil, China, India, Indonesia, Mexico, Russia and Turkiye) countries from 1992 to 2018, to ensure environmental sustainability in the background of the Sustainable Development Goals (SDGs). The study was analyzed using the ARDL estimator, robustness test and Dumitrescu Hurlin panel causality (DHC) test. Long-term empirical estimates from the PMG-ARDL technique have shown that TI and REC reduce the EF, that is, increase environmental sustainability. At this point, it is seen that TI s and REC help in reaching SDG-7 and 13 in E-7 countries. However, on the contrary, it has been determined that NRR and real income (GDP) increase the EF. Findings were confirmed using robustness methods. In the DHC test results, while there is a unidirectional causality relationship from TI to EF, from EF to NRR and trade openness, a bidirectional causality relationship was found among GDP and EF. This study suggests that policy makers should focus on implementing environmentally friendly equipment to reduce environmental degradation, increase the share of REC and focus on sustainable development within the framework of the SDGs.
