A stabilized ﬁnite element method for modeling dispersed multiphase ﬂows using orthogonal subgrid scales

We propose a ﬁnite-element formulation for simulating multi-component ﬂows occupying the same domain with spatially varying concentrations. Each constituent is assumed to behave as an incompressible Newtonian ﬂuid, and solutions are sought for the velocities and volume fractions of each phase, as well as the common pressure. Stabilization terms are derived within the framework of the variational multiscale method based on an approximation of the ﬁnite-element residual to achieve control of the pressure and volume fractions. We utilize the concept of term-by-term stabilization in conjunction with orthogonal subgrid scales, thus incorporating only those terms of the residual essential to obtain stability and projecting them on a space orthogonal to the ﬁnite element space. The resulting system of equations is solved in a monolithic manner, requiring a small number of nonlinear iterations. Several benchmark tests have been performed to conﬁrm the stability and optimal asymptotic convergence rates for linear and higher-order elements using the proposed formulation.
A NOVEL ULTRA-WIDEBAND DESIGN OF RIDGED SIW MAGIC-T

In order to obtain a wideband sum-and-difference network, a novel ridged substrate integrated waveguide (RSIW) magic-T is designed. The proposed magic-T is composed of a five-layer RSIW structure. The signal input from the coaxial H-plane port is transmitted to RSIW through a stripline and split into two in-phase and equal signals at the output ports on the top and bottom layers because of the vertically symmetric structure. An E-plane SIW power divider is utilized to realize the E-plane input/output port of the magic-T. A remarkable bandwidth improvement is achieved due to the ridged structure and the wide bandwidth of a ladder-shape stripline optimized by genetic algorithm (GA). Measured results indicate that the magic-T has a fractional bandwidth (FBW) of 78.7% (6.4– 14.7 GHz) with return loss better than 18.1 dB and great isolation characteristics.
An effective scheme to address influence maximization for opinion formation in social networks

Influence maximization for opinion formation (IMOF) is an important problem in social networks, which aims to select most influential nodes and obtains the maximal propagation of the most ideal opinions. The existing studies on the IMOF primarily concentrate on the effective selection scheme of the most influential nodes (ie, seed nodes) and the improved opinion formation models. However, there is little work describing and defining the IMOF mathematically. In this paper, we formulate the IMOF problem mathematically and propose the weighted cooperation model to compute the opinions of network nodes. To determine the most influential nodes, an effective scheme (including the score of potential nodes (SPNs) and elimination of overlapping influence (EOI)) is proposed. By using the reverse propagation process of public opinion and dynamically adjusting the influence score of each node, SPN determines the sorting of network node within the finite iterations. Moreover, to better determine the initial seed nodes, the EOI is adopted to deal with the similarity and overlapping influence among these nodes with high influence score. Finally, to evaluate the performance of SPN, the number of positive nodes with the change of seed nodes and the times of iteration by SPN is compared with three mainstream algorithms in social network data sets. Simulation results show that the proposed scheme obtains superior number of positive nodes than the comparison algorithms.

MANAGEMENT OF SECONDARY ANGLE-CLOSURE GLAUCOMA IN ANTERIOR SEGMENT DYSGENESIS AND ANTERIOR MICROPHTHALMOS PATIENT

Introduction: The majority of cases of anterior segment dysgenesis (ASD) and anterior microphthalmia are known to be complicated by angle-closure glaucoma, which is also the primary cause of visual loss. Medical therapy of this secondary glaucoma is frequently ineffective, necessitating surgery. However, managing the surgery in an eye with a crowded anterior chamber is difficult. This study aimed to report the management of secondary angle-closure glaucoma in anterior segment dysgenesis and anterior micropthalmos patient. Case Report: : A 39-year-old woman presented to Glaucoma unit with chief complaint of pain on the right eye. She also noted blurred vision, redness, and headache approximately seven months before presentation. The patient had a history of glaucoma since 5 years old, but hadn’t regularly visit for a long time. The visual acuity was 1/60 and intraocular pressure (IOP) was 45. Anterior segment evaluation revealed scleral thinning with injection, microcornea, sclerocornea, hazy peripheral cornea, iridocorneal adhesion, shallow anterior chamber, iris transillumination defect and lens opacity. A-scan biometry showed normal axial length. She was diagnosed with secondary angle-closure glaucoma with anterior segment dysgenesis, anterior microphthalmia and presenile cataract of the right eye. The patient underwent combined phacotrabeculectomy, pars plana vitrectomy and intraocular lens implantation. Discussion: Surgical procedure is indicated if pharmacological therapy cannot control IOP and glaucoma progressivity, including trabeculectomy combined with cataract extraction. However, cataract extraction is more difficult in shallow anterior eye chamber because the working field is narrower and the distance between the cornea and lens is closer. Some strategies to prevent this include pars plana vitrectomy (VPP). Conclusion: Anterior segment dysgenesis, though rare, cause vision loss by glaucoma as complication. Treatment of secondary glaucoma aim to lowering IOP to halt its progression. Combined phacotrabeculectomy, pars plana vitrectomy and intraocular lens implantation was a safe procedure in this crowded anterior chamber eye.

Crowdsourcing Based 3d Modeling

Abstract. Web-based photo albums that support organizing and viewing the users’ images are widely used. These services provide a convenient solution for storing, editing and sharing images. In many cases, the users attach geotags to the images in order to enable using them e.g. in location based applications on social networks. Our paper discusses a procedure that collects open access images from a site frequently visited by tourists. Geotagged pictures showing the image of a sight or tourist attraction are selected and processed in photogrammetric processing software that produces the 3D model of the captured object. For the particular investigation we selected three attractions in Budapest. To assess the geometrical accuracy, we used laser scanner and DSLR as well as smart phone photography to derive reference values to enable verifying the spatial model obtained from the web-album images. The investigation shows how detailed and accurate models could be derived applying photogrammetric processing software, simply by using images of the community, without visiting the site.
The Impact of Shear Reinforcement Amount and Arrangement on the Shear Capacity of Shallow RC Beams: An Experimental Study

This study investigates the impact of shear reinforcement amount and arrangement on the shear capacity of shallow/wide RC beams. Seven specimens of shallow/wide beams with different ultimate shear reinforcement stress (μ.Fys), longitudinal spacing to depth ratio (S/d), and transversal spacing to depth ratio (S’/d) were tested under a monotonic three-point bending test. All the specimens were designed to fail at shearing. The results showed that the shear reinforcement was fully functioning until it yielded; also, the amount of shear reinforcement had the major impact on the shear capacity; in addition, the transverse spacing had more influence on the shear capacity than the longitudinal spacing. The measured shear capacities were compared to six design codes, in which the results ranged from 95% to 110%, with the Japanese code (JSCE) being the closest to the experimental results. Two AI-based predicting equations, “Genetic Programming” (GP) and “Evolutionary Polynomial Regression” (EPR), were also compared to the experimental, with accuracies of 78% and 86% of the measured capacities, respectively. Initial stiffness, final stiffness, dissipated energy, and ductility were all discussed for the seven specimens, with ultimate shear reinforcement stress being the most impactful on the total shear capacity of the wide beams.

Generation of Smoke Dataset for Power Equipment and Study of Image Semantic Segmentation

Fire in power equipment has always been one of the main hazards of power equipment. Smoke detection and recognition have always been extremely important in power equipment, as they can provide early warning before a fire breaks out. Compared to relying on smoke concentration for recognition, image-based smoke recognition has the advantage of being unaffected by indoor and outdoor environments. This paper addresses the problems of limited smoke data, difficult labeling, and insufficient research on recognition algorithms in power systems. We propose using three-dimensional virtual technology to generate smoke and image masks and using environmental backgrounds such as HDR (high dynamic range imaging) lighting to realistically combine smoke and background. In addition, to address the characteristics of smoke in power equipment, a dual UNet model named DS-UNet is proposed. The model consists of a deep and a shallow network structure, which can effectively segment the details of smoke in power equipment and handle partial occlusion. Finally, DS-UNet is compared with other smoke segmentation networks with similar structures, and it demonstrates better smoke segmentation performance.
A novel enemy of cancer: recent investigations into protozoan anti-tumor properties

Cancer remains a significant global health issue, despite advances in screening and treatment. While existing tumor treatment protocols such as surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy have proven effective in enhancing the prognosis for some patients, these treatments do not benefit all patients. Consequently, certain types of cancer continue to exhibit a relatively low 5-year survival rate. Therefore, the pursuit of novel tumor intervention strategies may help improve the current effectiveness of tumor treatment. Over the past few decades, numerous species of protozoa and their components have exhibited anti-tumor potential via immune and non-immune mechanisms. This discovery introduces a new research direction for the development of new and effective cancer treatments. Through in vitro experiments and studies involving tumor-bearing mice, the anti-tumor ability of Toxoplasma gondii, Plasmodium, Trypanosoma cruzi, and other protozoa have unveiled diverse mechanisms by which protozoa combat cancer, demonstrating encouraging prospects for their application. In this review, we summarize the anti-tumor ability and anti-tumor mechanisms of various protozoa and explore the potential for their clinical development and application.
Recent developments in Laue lens manufacturing and their impact on imaging performance

We report on recent progress in the development of Laue lenses for applications in hard X/soft gamma-ray astronomy. Here we focus on the realization of a sector of such a lens made of 11 bent Germanium crystals and describe the technological challenges involved in their positioning and alignment with adhesive-based bonding techniques. The accurate alignment and the uniformity of the curvature of the crystals are critical for achieving optimal X-ray focusing capabilities. We have assessed how the errors of misalignment with respect to the main orientation angles of the crystals affect the point spread function (PSF) of the image diffracted by a single sector. We have corroborated these results with simulations carried out with our physical model of the lens, based on a Monte Carlo ray-tracing technique, adopting the geometrical configuration of the Laue sector, the observed assembly accuracy and the measured curvatures of the crystals. An extrapolation of the performances achieved on a single sector to an entire Laue lens based on this model has shown that a PSF with half-power-diameter of 4.8 arcmin can be achieved with current technology. This has the potential to lead to a significant improvement in sensitivity of spectroscopic and polarimetric observations in the 50-600 keV band
Characterization of Klebsiella pneumoniae carrying the blaNDM-1 gene in IncX3 plasmids and the rare In1765 in an IncFIB-IncHI1B plasmid

Background Today, the blaNDM gene is widely distributed on several plasmids from a variety of Gram-negative bacteria, primarily in transposons and gene cassettes within their multidrug-resistant (MDR) regions. This has led to the global dissemination of the blaNDM gene. Methods The determination of class A beta-lactamase, class B and D carbapenemases was performed according to the recommendations of the Clinical and Laboratory Standards Institute (CLSI). Antimicrobial susceptibility testing was performed using both the BioMerieux VITEK2 system and antibiotic paper diffusion methods. Plasmid transfer was then evaluated by conjugation experiments and plasmid electroporation assays. To comprehensively analyze the complete genome of K. pneumoniae strain F11 and to investigate the presence of mobile genetic elements associated with antibiotic resistance and virulence genes, Nanopore and Illumina sequencing platforms were used, and bioinformatics methods were applied to analyze the obtained data. Results Our findings revealed that K. pneumoniae strain F11 carried class A beta-lactamase and classes B+D carbapenemases, and exhibited resistance to commonly used antibiotics, particularly tigecycline and ceftazidime/avibactam, due to the presence of relevant resistance genes. Plasmid transfer assays demonstrated successful recovery of plasmids pA_F11 and pB_F11, with average conjugation frequencies of 2.91×10-4 and 1.56×10-4, respectively. However, plasmids pC_F11 and pD_F11 failed in both conjugation and electroporation experiments. The MDR region of plasmid pA_F11 contained rare In1765, TnAs2, and TnAs3 elements. The MDR2 region of plasmid pB_F11 functioned as a mobile genetic “island” and lacked the blaNDM-1 gene, serving as a “bridge” connecting the early composite structure of bleMBL and blaNDM-1 to the recent composite structure. Additionally, the MDR1 region of plasmid pB_F11 comprised In27, TnAs1, TnAs3, and Tn2; and plasmid pC_F11 harbored the recent composite structure of bleMBL and blaNDM-1 within Tn3000 which partially contained partial Tn125. Conclusion This study demonstrated that complex combinations of transposons and integron overlaps, along with the synergistic effects of different drug resistance and virulence genes, led to a lack of effective therapeutic agents for strain F11, therefore its dissemination and prevalence should be strictly controlled.
A typological survey of the phonological behavior of implosives: Implications for feature theories

This paper presents the ﬁrst cross-linguistic investigation into the phonological behavior of implosive sounds. In many feature theories, implosives share features with obstruent sounds, plus some implosive-speciﬁc laryngeal feature. These feature theories predict, then, that implosives should pattern phonologically as a natural class with obstruents, to the exclusion of sonorants. We take a detailed look at the phonological patterning of implosives in six languages, and present results of a typological survey of implosives in 88 languages where implosives contrast with sonorants and obstruents at the same place of articulation. We ﬁnd that, despite previous feature-based proposals which assume that implosives are obstruents, implosives pattern with sonorants to the exclusion of obstruents in 38% of languages in our sample. Another 32% of languages show mixed behavior, where implosives pattern with both obstruents and sonorants, depending on the speciﬁc phonological process involved. We discuss the implications of our results for the phonological featural representation of implosives, and propose future historical and phonetic studies to further illuminate the cross-linguistic behavior of implosive sounds.
Tracking Endometrial Malacoplakia Through the Evolution of 2D and 3D Ultrasound and Histopathological Features

Malacoplakia is an uncommon disease characterized by chronic and granulomatous inflammation, which rarely involves the female genital tract. We describe the ecographic and histological evolution of the first case of a patient developing endometrial malacoplakia as a complication after a cesarean section. The patient, a 43-year-old woman, presented with pelvic pain one month after delivering by cesarean section and the initial suspicion was of retention of placental rests. We discuss the diagnostic challenges for this rare disease, highlighting the importance of considering endometrial malacoplakia as a possible diagnosis in patients with similar clinical presentations and the important role of 2D and 3D ultrasound in the diagnostic pathway. In literature, ultrasound findings in cases of endometrial malacoplakia are represented by hypoechoic thickening of the endometrial lining; hyperechoic thickening of the myometrium, and the presence of masses, nodules, cystic areas, or anechoic fluid within the endometrium. For the first time, we describe the evolution of endometrial malacoplakia through both ultrasound, 2D and 3D, and histopathological findings, from the acute to chronic stage of the disease.
