Geometric Sensitivity Index for the GNSS Using Inner Products of Line of Sight Vectors

Satellite selection and exclusion techniques have been applied to the global navigation satellite system (GNSS) with the aim of achieving a balance between navigational performance and computational efficiency. Conventional approaches to satellite selection based on the best dilution of precision (DOP) are excessively computational and complicated. This paper proposes a new method that applies a geometric sensitivity index of individual GNSS satellites. The sensitivity index is derived using the inner product of the line of sight (LOS) vector of each satellite. First, the LOS vector is computed, which accounts for the geometry between the satellite and user positions. Second, the inner product of each pair of LOS vectors is calculated, which indicates the proximities of the satellites to one another. The proximity can be determined according to the sensitivity of each satellite. A post-processing test was conducted to verify the reliability of the proposed method. The proposed index and the results of a conventional approach that measures the dilution of precision (DOP) were compared. The test results demonstrate that the proposed index produces results that are within 96% of those of the conventional approach and reduces the computational burden. This index can be utilized to estimate the sensitivity of individual satellites, obtaining a navigation solution. Therefore, the proposed index applies to satellite selection and exclusion as well as to the sensitivity analyses of multiple GNSS applications.
Protection and detection of physical hazards for the intelligent system under industrial Internet of Things by neural network

Aiming at detecting and avoiding many security risks brought by various intelligent equipment and sensors in industrial Internet of Things (IoT) intelligent system, the Kalman back propagation neural network (Kalman‐BPNN) algorithm is designed, based on the neural network and with the help of the unique advantages of Kalman filtering algorithm and back propagation neural network (BPNN) algorithm. Introductions are made on the architecture of IoT and the theory of system security, and descriptions are made on the principle and process of related algorithms in detail. The advantages of traditional algorithms are integrated to design a Kalman‐BPNN algorithm. The simulation experiment analysis is carried out, and the designed detection method is compared with the traditional detection method. The voltage test of the Kalman‐BPNN algorithm based on the neural network is no more than 4.1%, as the experiment shows. The true positive rate of Kalman‐BPNN algorithm is 91.121%, which is very close to the value of 1, indicating that the algorithm has a great probability to predict the normal voltage. The false positive rate is 9.341%, which is very close to 0, indicating that the algorithm has a small probability of false judgment.
miRNA-331-3p Affects the Proliferation, Metastasis, and Invasion of Osteosarcoma through SOCS1/JAK2/STAT3

MicroRNAs (miRNAs) are regulatory small noncoding RNAs that play a key role in several types of cancer. It has been reported that miR-331-3p is involved in the development and progression of various cancers, but there are few reports regarding osteosarcoma (OS). The public GEO database was used to analyze the survival difference of miR-331-3p in OS organizations. The level of cell proliferation assay was assessed by CCK-8 and colony formation. First, transwell and wound-healing assays were used to detect the transfer and invasion ability of miR-331-3p in OS. Second, TargetScan, miRDBmiR, TarBase, and dual-luciferase reporter gene assays were used to determine SOCS1 as a targeted regulator. Third, Western blot and immunohistochemistry were used to detect the expression of protein levels. Finally, a mouse model of subcutaneously transplantable tumors is used to evaluate the proliferation of OS in vivo. The low expression of miR-331-3p was negatively correlated with the overall survival of OS patients. Overexpression of miR-331-3p significantly inhibited cell proliferation, metastasis, and invasion. Moreover, miR-331-3p affected the occurrence and development of osteosarcoma by targeting the SOCS1/JAK2/STAT3 signaling pathway. Therefore, miR-331-3p reduces the expression of SOCS1 by combining with its 3′UTR, thereby activating the JAK2/STAT3 signaling pathway to regulate the progression of OS. This provides a new theoretical basis for the treatment of osteosarcoma.

Gram negative microorganisms were identified in 35(68.63%) of isolates and Acinetobacter species accounts for 10(28.57%) followed by Klebsiella pneumonia and E. coli 7(13.725%) each. Generally, higher resistance was observed with cephalosporins and penicillins, whereas sensitivity to carbapenems, PIP/TAZ, and amikacin was satisfactory. The mortality associated with intensive care infections was found to be 32.1%. Conclusion: This study revealed that the mortality rate associated with ICU infection was 32.1%. Early identification, targeted provision of antimicrobials based on microbiological culture and susceptibility result has to be implemented to have better outcome. Designs of future multicenter and large studies are crucial to improve outcome of critically ill patients.
GHz High Frequency TSV for 2.5D IC Packaging

TSV (Through Silicon Via) is the key enabling technology for 2.5D & 3D IC stacking solution in FCBGA (Flip Chip Ball Grid Array). As the 2.5D interposer design pushing toward smaller & shorter via due to high I/O density and high frequency requirement, the electrical performance of thinner interposer is therefore much more challenging in low signal loss performance for high frequency application and process. From the structure point of view, the silicon interposer is an additive layer between top side chip(s) and bottom side substrate, it is therefore an additional electrical interconnection which affects the signal propagation between chip(s) and substrate. Therefore, the performance of the TSV insertion loss in silicon interposer becomes critical, especially for above GHz application. Real measurement is conducted to validate the electrical performance of TSV interconnection up to 67GHz, and the wideband scalable model of TSV is also proposed and compared with the measured data. The measurement of this .
Intrusion Detection Using Payload Embeddings

Attacks launched over the Internet often degrade or disrupt the quality of online services. Various Intrusion Detection Systems (IDSs), with or without prevention capabilities, have been proposed to defend networks or hosts against such attacks. While most of these IDSs extract features from the packet headers to detect any irregularities in the network traffic, some others use payloads alongside the headers. In this study, we propose a payload-based intrusion detection scheme, <monospace>PayloadEmbeddings</monospace>, using byte embeddings of the payloads of network packets. We employ a shallow neural network to generate vector representations for bytes and their corresponding payloads. Our feature extraction technique is coupled with the <inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula>-Nearest Neighbours (<inline-formula> <tex-math notation="LaTeX">$k$ </tex-math></inline-formula>NN) algorithm for the classification of packets as intrusive or non-intrusive. In our experiments, we evaluated 34 publicly available datasets, and used ten distinct payload-based, labeled intrusion detection datasets to train and evaluate our approach. Our empirical results show that <monospace>PayloadEmbeddings</monospace> reaches between 75% and 99% accuracy across all datasets. Finally, we compare our approach to other state-of-the-art and traditional intrusion detection techniques. Our findings suggest that <monospace>PayloadEmbeddings</monospace> demonstrates significant advantages over the other techniques on most of the datasets.
Effect of Dolichos biflorus Seeds Based Functional Beverage on In Vitro Calcium Oxalate Crystallization in Human Urine

Calcium oxalate is the most common type of urolithiasis. The crystallization process includes nucleation, growth, and the aggregation of crystals. This study has used Dolichos biflorus seeds as a functional beverage to explore the role of its bioactive substances on the crystallization process of calcium oxalate in managing urolithiasis. A human urine model of in vitro calcium oxalate crystals was used in the study. Phytochemical screening of Functional beverage of Dolichos biflorus seeds was performed, and antioxidant activity was evaluated by measuring DPPH radical-scavenging activity, reducing power assay, and Hydrogen peroxide scavenging activity. Functional beverage of Dolichos biflorus seeds inhibited crystallization process by reducing aggregation of calcium oxalate crystals. The reduction in crystals aggregation helps prevent urolithiasis by keeping the crystals dispersed in the urine, controlling their size, and facilitating expulsion from the urinary tract. The results showed that the Functional beverage of Dolichos biflorus seeds has a significant quantity of flavonoids, glycosides, etc., and also possesses a significant antioxidant activity as evaluated by employing different antioxidant assays. Therefore, our findings suggested that the functional beverage of Dolichos biflorus seeds exhibited antiurolithiatic activity through inhibition of the crystallization process of the calcium oxalate process and significant antioxidant potential.
THE EFFECT OF SEED TREATMENT WITH NON-THERMAL PLASMA

The use of physical methods in agro-industrial production has recently become more widespread due to the desire to reduce the level of chemicals. The relevance of the work is also determined by the low level of use of plasma technologies in agricultural production. This work aims to study the effect of non-thermal plasma source discharges on barley of the Vladimir variety seed growth rates and the surface microbiota. During the work on the study of the effect of non-thermal plasma on the sowing qualities of spring barley, it was found that the plasma treatment, in general, does not have a negative or stimulating effect on the initial growth processes of barley seeds. Treatment of barley seeds leads to a decrease in the total microbial count of the surface microbiota. Thus, it has been experimentally established that the microwave plasmatron is suitable for processing seed material.
How Do Dancers Solve Their Choreographic Improvisational Problems?

Problem solving as a higher cognitive ability is a theoretical construct operating in cognitive science and cognitive psychology. The founders of cognitive science were united by a shared vision of the mind as a tool similar to a computer – i.e. one serving to solve problems by manipulating non-sensory and abstract symbols inside the system. In interdisciplinary research into dance, the term “choreographic problem solving” (Kirsh, Muntanyola, 2009b; Kirsh, 2011; Clements , Redding , Sell, May, 2018; Stevens & Malloch & McKechnie & Steven, 2003; Leach & deLahunta, 2015) has become current in the context of a broad conception of dance practice as the inventive creation of movement in response to choreographic tasks that are the stimulus for creating motor images (James, 1890) and mental images (Franklin, 1996). The purpose of this article is to present an interpretation of the concept of solving choreographic problems in the course of improvised dance. This analysis falls within the paradigms of embodied cognition and situated cognition concepts and theories and works on the basis of initial reports from research on the influence of metaphorical instructions on the solution of choreographic problems in dance improvisation. These initial reports relate to the first conclusions drawn from analyses of research materials taking the form of video recordings, questionnaires and in-depth interviews.

Cissus quadrangularis Aqueous Extract Attenuates Angiotensin II-Induced Hypertension In Urethane-Anesthetized Rats

Hypertension is a major cardiovascular problem resulting in significant mortality. Cissus quadrangularis having several pharmacological effects has not been evaluated for its ability to modulate blood pressure. Thus, the ability of C. quadrangularis aqueous extract (CQE) to modulate blood pressure was evaluated in normotensive and angiotensin II-induced hypertensive rats under urethane anesthesia. The animals were divided into four groups namely, control (saline injection), CQE (extract alone, 10 mg/kg), Ang II (Ang II alone, 0.5 µg/kg) and Ang II + CQE (Ang II + extract). All treatments were delivered by intravenous route and in Ang II + CQE group, Ang II was injected 30 min after injection of the extract. Hemodynamic parameters, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MABP), and heart rate (HR) were recorded by the BIOPAC system after the cannulation of the carotid artery and jugular vein. The results indicated that CQE lowered SBP, DBP, MABP and heart rate to varying degrees in normotensive rats compared to control groups. In case of angiotensin II-induced hypertension, CQE administration resulted in substantial decrease in SBP, DBP, and MABP which were raised by Ang II. CQE reduced SBP, DBP, and MABP by 12, 59, and 11%, respectively. It is worth noting that, while SBP was not brought down to baseline levels by CQE, DBP was, suggesting significant hypotensive/antihypertensive activity of CQE. Further research is required to determine the molecular mechanism of C. quadrangularis extract’s hypotensive/antihypertensive action and to conduct clinical trials to establish its optimal use as an antihypertensive therapeutic.
Analysis and design of robust storage elements in nanometric circuits

The stability of storage element circuits in the nanoscale era, such as memories and latches is evaluated and new circuit configurations for stability improvement are proposed in this dissertation. The stability and robustness of a given memory cell are usually evaluated by analyzing both static and dynamic behaviors during typical operation. In this dissertation, a 9T CMOS SRAM cell design at 32nm is first presented to improve static stability, power dissipation, and delay compared to the conventional SRAM cell as well as a detailed comparison with other designs found in the technical literature. Moreover, a dual-diameter Carbon Nanotube-based SRAM cell configuration with different threshold voltages is then designed; this cell shows significant improvements compared to its CMOS counterpart in terms of power consumption and stability. Two memory cell configurations at 32nm CMOS technology for improving dynamic stability are then proposed in this dissertation and simulation results show significant improvement in dynamic stability. In this work, a comprehensive treatment (model, analysis and design) for hardening storage elements against a soft error resulting in multiple node upsets is also presented. A novel 13T memory cell configuration is proposed and simulated to show a significantly better tolerance to the likely multiple node upset. Simulation results have confirmed that the proposed memory cell accomplish an excellent soft error tolerance through hardening and an impressive power-delay product compared with the other commonly used hardened design. For the latch, the stability of a latch cell is only judged by the Critical Charge (Qcrit) when the latch is not transparent. Three new hardened designs for CMOS latches at 32nm feature size are proposed. For the latch design, a novel design metric

The survival of coral larvae as early phase of coral life is very important for their viability in environmen. This research aims to determine the survival of Acropora sp planula at different densities intensive nursery, and also to khow the critical survival time of them. This research method was used experiment in density of larvae were held in control laboratory. The planula were rearing ini small container 200 ml of water while the lavae density were used namely 0.5; 1.0, 1.5, 2.0 larvae / ml. The results indicated that survival rate for larvae of different densities (0.5 larvae/ml; 1.0 larvae/ml; 1.5 larvae/ml; 2.0 larvae/m) did not show any significant difference (P>0.05). the highest survival rate of planula larvae was in the treatment with a density of 1.5 larvae/ml and the lowest from a density of 2.0 larvae/ml, and the most larval mortality was in the first 12 hours of rearing, due to the degree of adaptation of larvae to the rearing water medium in all treatment units, then death coral larvae decreased exponentially. This research will be very useful for efforts to restore coral reefs sexually, so as to reduce the impact of exploitation of coral seedlings which are often taken for asexual coral reef restoration as is often done throughout the world's coral reefs.
Prevalence and Pregnancy Outcome of Mullerian Anomalies in Infertile Women: A Retrospective Study

Background: Uterine anomalies arise if there is agenesis of one or two mullerian ducts, or absence of fusion or reabsorption of the septum between these ducts. The process may be partial or total and affect one or multiple parts of the tract. Aims: This study was done to assess the distribution of various types of mullerian anomalies in infertile women, their classification based on ESHRE and AFS, associated anomalies, types of diagnostic modalities used, surgical interventions done(if any), various types of infertility treatment used and their outcomes. Setting and Design: A retrospective analysis in a tertiary level hospital. Materials and Methods: This was a retrospective study in which the women found to have mullerian anomalies were recruited from infertility clinic from July 2019 to March 2020.They were classified according to ESHRE and AFS criteria and their records were analyzed after taking various factors like age, ovarian reserve, duration of infertility, treatment given , associated ovarian and tubal factors and pregnancy outcomes. Statistical Analysis: Analysis was performed in Excel. Results: There were 30 women with mullerian anomalies. Unicornuate uterus was most common anomaly . Four women required septoplasty in view of septate uterus. Five women had associated renal anomalies in form of shrunken kidney and ectopic kidney. Most of these women were considered for controlled ovarian stimulation followed by intrauterine insemination. In our study 16.6% women had successful pregnancy outcome. Conclusion: Mullerian anomalies continue to attract infertility specialist as they pose challenge in making clear diagnosis and its management as obstetrics outcomes are excellent after septum resection in women with septate uterus and conservative management in women with other anomalies. Proper work up of infertility and its management varies from case to case and associated factors like endometriosis, male factor, polycystic ovarian syndrome etc.
