A Not So Simple Matter of Software; The Evolution of Mathematical Software: Software and Algorithms Follow the Hardware

Each generation of computer architecture has brought new challenges to achieving high performance mathematical solvers, necessitating development and analysis of new algorithms, which are then embodied in software libraries. These libraries hide architectural details from applications, allowing them to achieve a level of portability across platforms from desktops to world-class high performance computing (HPC) systems. On the eve of exascale computing, traditional wisdom may no longer apply. A range of algorithmic techniques are emerging in the context of exascale computing, many of which defy the common wisdom of HPC and are considered unorthodox but could turn out to be a necessity in the near future.
Scenery Soundscaping using Cross-Modal Information Retrieval

: Human beings associate certain sceneries with certain ambient sounds. A picture of the ocean can make us think of the sound of ocean waves, or a picture of a busy market can make us imagine the sounds of people talking and the sound of vehicles. But computers do not have this innate ability to associate audio to a visual image. If you separate the audio from its corresponding video, the computer would not be able to associate these with each other, unless programmed to do so explicitly. Cross-Modal Information Retrieval (CMIR) is a technique that measures similarities between different types of data, usually media, which here would be audio in the form of mp3 files, and images in the form of jpg files. The Scenery Soundscaping System accurately predicts the ambient sounds that you would hear in the scenery of a particular image using this technique. The project also creates a web app for the user to provide image inputs to the Scenery Soundscaping System and to listen to the soundscape predicted by it.
A Cell-Based Model of Angiogenesis Suggests That Vascular Stabilisation Can Result From Flow-Based Inhibition of Chemotaxis

Angiogenesis, the process of blood vessel sprouting and remodelling from existing vessels, is a process of large medical concern. Research shows that the vascular network remodels itself during the process of angiogenesis under the inﬂuence of blood ﬂow, through sensing endothelial wall shear stress (WSS), where endothelial cells (ECs) migrate up the ﬂow gradient such that high ﬂow vessels are stabilised whereby its cells take on a quiescent state. We propose the hypothesis that the cellular migration might result from ﬂow-based inhibition of chemotaxis. Speciﬁcally, it is our objective to investigate whether the inhibition of chemotaxis by ﬂow velocity is suﬃcient to promote cellular migration. Biologically, we assume that wall shear stress can be sensed and relayed through VE-cadherin, VEGFR2 and PECAM1. These mechanisms could potentially be coupled through NO and ROS which have been shown to inﬂuence chemotaxis sensitivity. We furthermore assume that endothelial cells, in addition to sensing, also secrete chemoattractants. The Cellular Potts Model (CPM) will be used to simulate the process of ﬂow-based remodelling We expand the two-dimensional model with haemodynamics, by means of the Hagen-Poiseuille equation. The equation is a physical law modelling pressure diﬀerence, from which other haemodynamics can be extracted, on the assumption of laminar ﬂow. The assumption of laminar blood ﬂow has been shown to be justiﬁed in capillaries. The CPM model is computationally modelled in the Tissue Simulation Toolkit, an open source C++ library for simulating vascular morphogenesis. Whereas previous cell-based models lacked the simulation of haemodynamic, our model simulates blood ﬂow dynamics and derives these computations in an eﬃcient manner, whereby the necessary steps of segmentation and skeletonisation of the vasculature are solved through a dynamic process. Simulations where performed where the ﬂow velocity has been calculated throughout the vasculature, with the chemotaxis component linearly inhibited with ﬂow velocity. Results have shown that ﬂow-based inhibition of chemotaxis leads to clustering of the vascular network into small and large vessels, the latter resembling arterioles. ECs in smaller vessels remain motile and frequently migrate into larger high ﬂow vessels where they take on a quiescent state. The arising arterioles furthermore act as stable vessels that span over the CPM lattice and show a high volume ﬂow rate. Our simulations quantitatively reproduce vascular stabilisation by means of structural vascular diﬀerentiation through ﬂow-based inhibition of chemotaxis. We recommend both the application of dynamic updates and make the proposal for future researchers to take on the question whether ﬂow-inhibited chemotaxis also leads to vascular remodelling with in vitro or in vivo research models.
HindiMD: A Multi-domain Corpora for Low-resource Sentiment Analysis

Social media platforms such as Twitter have evolved into a vast information sharing platform, allowing people from a variety of backgrounds and expertise to share their opinions on numerous events such as terrorism, narcotics and many other social issues. People sometimes misuse the power of social media for their agendas, such as illegal trades and negatively influencing others. Because of this, sentiment analysis has won the interest of a lot of researchers to widely analyze public opinion for social media monitoring. Several benchmark datasets for sentiment analysis across a range of domains have been made available, especially for high-resource languages. A few datasets are available for low-resource Indian languages like Hindi, such as movie reviews and product reviews, which do not address the current need for social media monitoring. In this paper, we address the challenges of sentiment analysis in Hindi and socially relevant domains by introducing a balanced corpus annotated with the sentiment classes, viz. positive, negative and neutral. To show the effective usage of the dataset, we build several deep learning based models and establish them as the baselines for further research in this direction.
Analysis of the Influencing Factors of Immunological Nonresponders in Wuhan, China

Objective CD4+ cell recovery is hampered in some human immunodeficiency virus (HIV)-infected patients, despite a successful highly active antiretroviral therapy (HAART) with suppressed viral replication. We investigated the factors that might have hindered the CD4+ cell recovery in these patients. Methods In this retrospective study, we collected the data of all immune nonresponders (INRs) in Wuhan, China, until the end of 2020. A linear model was constructed based on the data from 220 patients with baseline and follow-up records. The response variables in this study were the CD4+ cell count increase. The predictor variables considered in this study were those factors likely to affect the CD4+ cell recovery. Results Our findings revealed that the plasma HIV-1 viral load of all patients was suppressed and 87.3% patients' CD4+ cells was increased after more than one year of the HAART treatment. In addition, their last follow-up showed a significant reduction in complications. In our results, the body mass index (BMI), number of months since HIV diagnosis to HAART start, and nonuse of co-trimoxazole were negatively correlated with the increase in CD4+ cells (P < 0.05). However, there were positive associations between serum creatinine levels and CD4+ cell recovery (P < 0.05). Further stratified analyses indicated that the associations between HAART replacement or creatinine usage and CD4+ cell growth were only observed in those participants with a BMI <18.5 (P < 0.05). Conclusions An early initiation of HAART and co-trimoxazole preventive therapy (CPT) can promote immune reconstitution. BMI and serum creatinine can serve as monitoring indicators of immune reconstitution prognosis after the HAART.
Improved Metal Cation Optosensing Membranes through the Incorporation of Sulphated Polysaccharides

Optosensing chitosan-based membranes have been applied for the detection of heavy metals, especially in drinking water. The novelty of this study is based on the use of sulphated polysaccharides, in such optosensing membranes, aiming at an improved analytical performance. The sulphated polysaccharides, such as ulvan, fucoidan and chondroitin sulfate, were extracted from by-products and wastes of marine-related activities. The membranes were developed for the analysis of aluminum. The variation in the visible absorbance of the sensor membranes after the contact between the chromophore and the aluminum cation was studied. The membranes containing sulphated polysaccharides showed improved signals when compared to the chitosan-only membrane. As for the detection limits for the membranes containing ulvan, fucoidan and chondroitin sulfate, 0.17 mg L−1, 0.21 mg L−1 and 0.36 mg L−1 were obtained, respectively. The values were much lower than that obtained for the chitosan-only membrane, 0.52 mg L−1, which shows the improvement obtained from the sulphated polysaccharides. The results were obtained with the presence of CTAB in analysis solution, which forms a ternary complex with the aluminum cation and the chromophore. This resulted in an hyperchromic and batochromic shift in the absorption band. When in the presence of this surfactant, the membranes showed lower detection limits and higher selectivity.

Tingkat Maturasi Oosit Sapi Bali pada Media TCM 199 dengan Penambahan Hipotaurin

Maturasi oosit merupakan salah satu langkah penting dalam pelaksanaan fertilisasi in vitro untuk pelaksanaan transfer embryo. Oosit hasil koleksi baik secara aspirasi maupun slicing pada umumnya belum mencapai fase MII yang dibutuhkan untuk fertilisasi in vitro sehingga perlu dilakukan maturasi oosit. Tujuan penelitian adalah untuk mengetahui tingkat maturasi oosit sapi bali pada media TCM 199 dengan penambahan hipotaurin. Oosit berasal dari ovarium yang diperoleh dari rumah potong hewan Pesanggaran Denpasar dan dikoleksi dengan metode slicing. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari tiga kelompok yaitu kelompok I / kontrol (P0: media maturasi tanpa hipotaurin), kelompok II (P1: media maturasi dengan penambahan hipotaurin dengan konsentrasi 2 mMol dan kelompok III (P2: media maturasi dengan penambahan hipotaurin dengan konsentrasi 4 mMol dengan masing-masing kelompok terdiri dari 27 ulangan. Maturasi oosit dilakukan dengan cara inkubasi selama 24 jam dalam inkubator dengan suhu 38,5 0C dengan tekanan CO2 5 %. Hasil penelitian menunjukkan bahwa tingkat ekspansi sel kumulus hingga tahap cumulus oocyte complexes (COCs) pada kelompok P1 tidak berbeda nyata dibandingkan kelompok P0 (p>0,05), namun kelompok P2 menunjukkan perbedaan yang nyata (p<0,05). Pada tingkat kematangan inti, penambahan hipotaurin tidak menyebabkan perbedaan yang nyata (p>0,05) pada tingkat GVBD, namun pada tingkat MI terdapat perbedaan yang nyata (p<0,05) antara kelompok P0 dengan P1 dan P2, sedangkan pada tingkat MII tidak terdapat perbedaan yang nyata (p>0,05) antara P0 dengan P1 namun berbeda nyata (p<0,05) antara P0 dengan P2. Dari hasil peneltian dapat disimpulkan bahwa penambahan hipotaurin dengan konsentrasi 4 mM pada media maturasi oosit TCM 199 dapat meningkatkan tingkat ekspansi sel kumulus mencapai COCs dan meningkatkan tingkat kematangan inti mencapai fase MII.

Whole Genome Sequencing Applied in Familial Hamartomatous Polyposis Identifies Novel Structural Variations

Hamartomatous polyposis syndromes (HPS) are rare cancer-predisposing disorders including Juvenile polyposis (JPS), Peutz–Jeghers (PJS) and PTEN hamartomatous syndromes (PHS). Penetrant mutations in corresponding genes (SMAD4, BMPR1A, STK11, PTEN and AKT1), are usually diagnosed via a next-generation-sequencing gene panel (NGS-GP) for tailored surveillance and preimplantation testing for monogenic disorders (PGT-M). Five probands with HPS phenotype, with no genetic diagnosis per genetic workup, underwent whole-genome sequencing (WGS) that identified structural genetic alterations: two novel inversions in BMPRA1 and STK11, two BMPR1A-deletions, known as founders among Bukharan Jews, and BMPR1A microdeletion. BMPR1A inversion was validated by “junction fragment” amplification and direct testing. PGT-M was performed via multiplex-PCR and enabled successful birth of a non-carrier baby. WGS may be considered for HPS patients with no NGS-GP findings to exclude structural alterations.
Construction of an Epithelial-Mesenchymal Transition-Related Model for Clear Cell Renal Cell Carcinoma Prognosis Prediction

Background A rising amount of data demonstrates that the epithelial-mesenchymal transition (EMT) in clear cell renal cell carcinomas (ccRCC) is connected with the advancement of the cancer. In order to understand the role of EMT in ccRCC, it is critical to integrate molecules involved in EMT into prognosis prediction. The objective of this project was to establish a prognosis prediction model using genes associated with EMT in ccRCC. Methods We acquired the mRNA expression profiles and clinical information about ccRCC from TCGA database. In this study, we measured differentially expressed EMT-related genes (DEEGs) by two comparison groups (tumor versus normal tissues; “stages I-II” versus “stages III-IV” tumor tissues). Based on classification and regression random forest models, we identified the most important DEEGs in predicting prognosis. Afterwards, a risk-score model was created using the identified important DEEGs. The prediction ability of the risk-score model was calculated by the area under the curve (AUC). A nomogram for prognosis prediction was built using the risk-score in combination with clinical factors. Results Among the 72 DEEGs, the classification and regression random forest models identified six hub genes (DKK1, DLX4, IL6, KCNN4, RPL22L1, and SPDEF), which exhibited the highest importance values in both models. Through the expression of these six hub genes, a novel risk-score was developed for the prognosis prediction of ccRCC. ROC curves showed the risk-score performed well in both the training (0.749) and testing (0.777) datasets. According to the survival analysis, individuals who were separated into high/low-risk groups had statistically different outcomes in terms of prognosis. Besides, the risk-score model also showed outstanding ability in assessing the progression of ccRCC after treatment. In terms of nomogram, the concordance index (C-index) was 0.79. Additionally, we predicted the differences in response to chemotherapy drugs among patients from low- and high-risk groups. Conclusion Gene signatures related to EMT could be useful in predicting ccRCC prognosis.
Analysis of VOCs in Urine Samples Directed towards of Bladder Cancer Detection

Bladder cancer is one of most common types of cancer diagnosed in the genitourinary tract. Typical tests are costly and characterized by low sensitivity, which contributes to a growing interest in volatile biomarkers. Head space solid phase microextraction (SPME) was applied for the extraction of volatile organic compounds from urine samples, and gas chromatography time of flight mass spectrometry (GC×GC TOF MS) was used for the separation and detection of urinary volatiles. A cohort of 40 adult patients with bladder cancer and 57 healthy persons was recruited. Different VOC profiles were obtained for urine samples taken from each group. Twelvecompounds were found only in the samples from theBC group.The proposed candidate biomarkers are butyrolactone; 2-methoxyphenol; 3-methoxy-5-methylphenol; 1-(2,6,6-trimethylcyclohexa-1,3-dien-1-yl)-2-buten-1-one; nootkatone and 1-(2,6,6-trimethyl-1-cyclohexenyl)-2-buten-1-one.Since most of the studies published in the field are proving the potential of VOCs detected in urine samples for the screening and discrimination of patients with bladder cancer from healthy, but rarely presenting the identity of proposed biomarkers, our study represents a novel approach.
An SIW Pillbox-Based Compact Dual-Polarized Multibeam Antenna With Passive 2-D Beam Scanning Capability

In this brief, a dual-polarized multi-beam antenna is proposed based on substrate integrated waveguide (SIW) pillbox beamforming networks (BFNs). By using a rotationally symmetrical frequency scanning leaky-wave antenna (LWA) array and four SIW pillbox BFNs, the 2-D beam steering capability is realized for two polarizations. Due to the rotationally symmetrical geometric characteristic of the LWA, the orthogonally placed BFNs can excite orthogonally polarized beams. A stable gain with a wide beam scanning range in the limited bandwidth is realized, where only the backward to broadside scanning region of the LWA is used, and the forward radiation is compensated by the axisymmetric BFN. Moreover, the stacked layout of the multi-layer antenna structure greatly helps realize miniaturization. The proposed antenna can provide ±35° beam scanning range by switching 7 ports in the multi-beam plane and ±31° frequency beam scanning range within the bandwidth of 21 GHz to 27.5 GHz. The advantages of the proposed antenna, including dual-polarization, 2-D beam scanning, low profile, compact size, and low cost, make it a very appropriate choice in millimeter-wave multi-beam radars systems.
Computers & Graphics

We introduce Vision UFormer (ViUT), a novel deep neural long-range monocular depth estimator. The input is an RGB image, and the output is an image that stores the absolute distance of the object in the scene as its per-pixel values. ViUT consists of a Trans-former encoder and a ResNet decoder combined with the UNet style of skip connections. It is trained on 1M images across ten datasets in a staged regime that starts with easier-to-predict data such as indoor photographs and continues to more complex long-range outdoor scenes. We show that ViUT provides comparable results for normalized relative distances and short-range classical datasets such as NYUv2 and KITTI. We further show that it successfully estimates absolute long-range depth in meters. We validate ViUT on a wide variety of long-range scenes showing its high estimation capabilities with a relative improvement of up to 23%. Absolute depth estimation finds application in many areas, and we show its usability in image composition, range annotation, defocus, and scene reconstruction. Our models are available at cphoto.fit. vutbr.cz / viut . ©
SHEAF INTERPRETATIONS FOR GENERALISED PREDICATIVE INTUITIONISTIC SYSTEMS

A sun reflector composed of an upstanding frame that supports a flexible and portable sun reflector or solarium structure. The frame is collapsible and the reflector structure folds to allow the sun reflector to be easily stored and transported. The reflector structure is provided with a dark, heat absorbing and retaining outer surface, and a light sun reflective inner surface and floor. When in use, the sun reflector is positioned to expose the reflector interior and floor to direct sunlight entering through an open frontal area such that a sun bather positioned on the reflector floor is exposed to both direct and reflected sunlight.
Global Optimization, the Gaussian Ensemble, and Universal Ensemble Equivalence.

Given a constrained minimization problem, under what conditions does there exist a related, unconstrained problem having the same minimum points? This basic question in global optimization motivates this paper, which answers it from the viewpoint of statistical mechanics. In this context, it reduces to the fundamental question of the equivalence and nonequivalence of ensembles, which is analyzed using the theory of large deviations and the theory of convex functions. In a 2000 paper appearing in the Journal of Statistical Physics, we gave necessary and sufficient conditions for ensemble equivalence and nonequivalence in terms of support and concavity properties of the microcanonical entropy. In later research we significantly extended those results by introducing a class of Gaussian ensembles, which are obtained from the canonical ensemble by adding an exponential factor involving a quadratic function of the Hamiltonian. The present paper is an overview of our work on this topic. Our most important discovery is that even when the microcanonical and canonical ensembles are not equivalent, one can often find a Gaussian ensemble that satisfies a strong form of equivalence with the microcanonical ensemble known as universal equivalence. When translated back into optimization theory, this implies that an unconstrained minimization problem involving a Lagrange multiplier and a quadratic penalty function has the same minimum points as the original constrained problem. The results on ensemble equivalence discussed in this paper are illustrated in the context of the Curie–Weiss–Potts lattice-spin model.
