Finite element modelling of the Swiss plate geophone bedload monitoring system

ABSTRACT Drop experiments with quartz spheres in a flume setting were performed to investigate the dynamic signal response of the Swiss plate geophone bedload monitoring system for varying particle size, vertical impact velocity, and impact location. For a similar sphere impact set-up, the finite element method was used to determine the propagation characteristics of the stress wave in the structure of the monitoring system. The experimental and numerical results showed a qualitative and partially quantitative agreement in the changes in the number of signal impulses per particle mass, the amplitude, and the centroid frequency with increasing colliding sphere size. These parameters characterizing the geophone vibrations also showed qualitatively similar dependencies with increasing bedload size as field measurements show with natural particles and a theoretical model. The findings of this study contribute to the understanding of the signal response of the monitoring system, which may result in improving bedload grain size classifications.
Salivary Gland Toxicity of PSMA-Targeted Radioligand Therapy with 177Lu-PSMA and Combined 225Ac- and 177Lu-Labeled PSMA Ligands (TANDEM-PRLT) in Advanced Prostate Cancer: A Single-Center Systematic Investigation

Purpose: PSMA-targeted radioligand therapy (PRLT) is a promising treatment option for patients with metastatic castration-resistant prostate cancer (mCRPC). However, a high uptake of the radiopharmaceutical in the salivary glands (SG) can lead to xerostomia and becomes dose-limiting for 225Ac-PSMA-617. This study investigated the sialotoxicity of 177Lu-PSMA-I&T/-617 monotherapy and co-administered 225Ac-PSMA-617 and 177Lu-PSMA-617 (Tandem-PPRLT). Methods: Three patient cohorts, that had undergone 177Lu-PSMA-I&T/-617 monotherapy or Tandem-PRLT, were retrospectively analyzed. In a short-term cohort (91 patients), a xerostomia assessment (CTCAE v.5.0), a standardized questionnaire (sXI), salivary gland scintigraphy (SGS), and SG SUVmax and the metabolic volume (MV) on 68Ga-PSMA-11-PET/CT were obtained before and after two cycles of 177Lu-PSMA-I&T/-617. In a long-term cohort, 40 patients were similarly examined. In a Tandem cohort, the same protocol was applied to 18 patients after one cycle of Tandem-PRLT. Results: Grade 1 xerostomia in the short-term follow-up was observed in 22 (24.2%) patients with a worsening of sXI from 7 to 8 at (p < 0.05). In the long-term cohort, xerostomia grades 1 to 2 occurred in 16 (40%) patients. SGS showed no significant changes, but there was a decline of the MV of all SGs. After Tandem-PRLT, 12/18 (66.7%) patients reported xerostomia grades 1 to 2, and the sXI significantly worsened from 9.5 to 14.0 (p = 0.005), with a significant reduction in the excretion fraction (EF) and MV of all SGs. Conclusion: 177Lu-PSMA-I&T/-617 causes only minor SG toxicity, while one cycle of Tandem-PRLT results in a significant SG impairment. This standardized protocol may help to objectify and quantify SG dysfunction.
Microbial Growth Of Lactobacillus Delbrueckii Ssp. Bulgaricus B1 In A Complex Nutrient Medium (MRS-Broth)

The microbial growth of the probiotic strain Lactobacillus delbrueckii ssp. bulgaricus B1, cultivated in a complex nutrient medium (MRS-broth), was studied in the present work. The complex nutrient medium provides not only the carbon source necessary for the growth of biomass, but also all the additional sources of nitrogen, phosphorus and other components that the biomass needs for its growth. The use of non-structural mathematical dependences determines the optimal conditions (substrate concentration) for the accumulation of biomass or lactic acid, depending on the needs of the specific production.
Insightful and comprehensive formularization of frequency–amplitude formula for strong or singular nonlinear oscillators

The comprehensive formularization of the frequency–amplitude formula is the main interest in this work to cover higher powers of the restoring force which are not limited to cubic powers. Three equivalent styles of the generalized frequency amplitude have been performed. In addition, the restoring force is not restricted to an odd function in which the non-secular forces are included. Three forms of the non-secular forces have been formulated for the first time and treated as non-homogenous of the linearized Duffing oscillator. The modified style of He’s formula has been applied to the singular oscillator using the enhanced potential function. The simplicity of the present approach provides extra advantages for high nonlinearity vibration. This method enriches the analysis with more details in new dimensions.
Volumetric Evaluations of Full-Arch Implant Supported Restorations and Their Role on Patients' Quality of Life: A Mixed-Model Analysis

Introduction Full-arch, implant-supported hybrid restorations, employing tilted implants, can offer an efficient way of treating edentulous patients. Several factors, such as the timing of implant placement and the inclination of the fixture, can have a detrimental effect on their stability. This retrospective study is aimed at discerning the role played by those factors. Materials and Methods Patients treated with full-arch, implant supported restorations were selected for this study; cone-beam computed tomography (CBCT) images, taken 3 months and 3 years after delivery of the final restoration, as well as peri-implant values, were obtained and compared; bone loss was measured on four sites for each implant and then averaged. These patients were recalled, and the OHIP-5 questionnaire was administered. Results 21 patients, with a mean age of 53 years, were included in the present analysis. 108 implants were placed, and 25 Toronto prostheses were delivered. According to a mixed-model analysis, tilted implants (0.51, p < 0.001) had a higher rate of bone loss, while implants placed in a healed ridge suffered less bone loss than immediate implants (-0.21, p < 0.001). Patient-level variables have a significant effect on this variable, as implants coming from the same subject share a similar risk of bone loss. The mean response to the self-administered OHIP-5 questionnaire was 1.53 ± 0.29; other variables did not have a statistically significant effect on this outcome. Discussion/Conclusions. The results of the present study show that Toronto bridges prostheses are an efficient procedure for treating edentulous patients, as their oral-related quality of life is reported as satisfactory even 7 years after delivery of the restoration. Tilted and immediate implants are more at risk of bone loss. Implants coming from the same subject share a similar risk of bone loss.
Twinning and Ovulation Rate for Sustainable Production in Cattle

Profits is very important in most industries and determined by the cost and amount of products generated. In the livestock industries, higher number of viable animals produced will improve the economies of scale, hence, their profit. In general, twinning can be a good approach to increase reproductive capacity, and consequently the production volume. Cattle are monovular animal, typically give birth to one offspring and multiple birth is rare. Multiple gestation is mostly unfavorable in the dairy industry due to their negative impact on reproductive and production performance on cow and calf. Twinning is highly correlated to ovulation rate and various genes that are affecting hyperprolificacy in sheep have been identified. Many studies have reported quantitative trait loci (QTL) that are associated with high ovulation rate and twinning in cattle. Besides the genetic factor, twinning can also be induced via hormonal methods. Knowledge on the factors that causing hyperprolificacy can assist the breeders or farmers for their selection, based on their objectives and strategy.
The outcome of Pleurodesis in Malignant Pleural Effusion

Background: Accumulation of fluid in pleural space, which is malignant in nature, is secondary to lung, breast or ovarian tumors. Metastatic Adeno Ca is most commonly seen in male and breast Ca is most commonly seen in female. It indicates advanced disease and reduced survival. Aim: Is to study prospectively thirty patients with malignant pleural effusion according to their clinical presentation, ways of diagnosis, and methods of chemical pleurodesis. Patient and methods: Data of thirty patients with malignant pleural effusion collected and analyzed using a form to categorize them according to their age, gender, presenting features, imaging studies and procedure performed to drain the fluid and to arrange chemical pleurodesis. Results: Eighteen patients were male; twelve patients were female in a ratio of 1.5:1. The youngest was 52 years old while the oldest was 81 years old. The mean age was 65.8 ±7.34. The most frequent presenting features were cough and dyspnea. Imaging studies showed that eleven patients had left sided effusion with underlying mass. Eight patients had right sided effusion with underlying mass while the remaining eleven patients had only effusion. Twenty patients received (Talc) and ten patients received (Bleomycin) with comparable recurrence rate of the effusion, in seven patients out of 20 in Talc (35%) and in three out of 10 patients received Bleomycin (30%). Conclusion: Malignant pleural effusion should be drained nearly complete evacuation; regardless the primary cause, prior to installation of agent for pleurodesis and both (Talc & Bleomycin) can be used with comparable results and recurrence
Temporal Associations between Religiosity and Subjective Well-Being in a Nationally Representative Australian Sample

ABSTRACT This study examined the between-person and within-person associations between 4 components of subjective well-being (i.e., general life satisfaction, satisfaction with life domains, positive affect, and negative affect) and 2 components of religiosity (i.e., religious salience and religious participation). Data were drawn from the Household, Income, and Labor Dynamics in Australia (HILDA) Survey, collected 5 times between 2004 and 2018. The Random-Intercept Cross-Lagged Panel Model was used to analyze the data. Results showed weak between-person associations between the components of religiosity and subjective well-being. At the within-person level, the cross-lagged associations between religiosity and subjective well-being variables were trivial and nonsignificant. This indicates a lack of robust temporal associations between religiosity and subjective well-being when measured at intervals of a few years.
A Novel Low-Power Compression Scheme for Systolic Array-Based Deep Learning Accelerators

The proliferation of deep learning algorithms has catalyzed their utilization to solve a multitude of real-world problems. Algorithms such as deep neural networks (DNNs) are compute- and power-intensive, thereby accentuating the development of hardware platforms like DNN inference accelerators. However, inference execution of large DNNs in resource-constrained environments induces energy bottlenecks in these accelerators. Since large DNNs consist of hundreds of millions of trained parameters, accessing them from the accelerator memory incurs substantial energy. To address this challenge, we propose HardCompress, which, to the best of our knowledge, is the first low-power solution that uses traditional compression strategies pertaining to commercial DNN accelerators in resource-constrained IoT edge devices. The three-step approach involves hardware-based post-quantization trimming of weights, followed by their dictionary-based compression and subsequent decompression by a low-power hardware engine during inference in the accelerator. We evaluate the proposed solution on lightweight networks trained on the MNIST dataset, the compact model trained on the CIFAR-10 dataset, and large DNNs trained on the ImageNet dataset. Performance of HardCompress at different quantization levels has been analyzed. Furthermore, to quantify the effectiveness of the proposed solution, an energy framework that contrasts the DRAM energies of the original and HardCompressed models has been developed. Finally, a fault injection framework which compares the fault resilience of the original model with its HardCompressed counterpart is also proposed. Our results exhibit that HardCompress, without any performance degradation in large DNNs, furnishes a maximum compression of 99.27%, equivalent to $137\times $ reduction in memory footprint and 0.07 J for 8-bit quantization in the systolic array-based DNN accelerator. Furthermore, our proposed low-power decompression engine incurs an area overhead of only 0.02%; thus, enabling HardCompress’ utilization in resource-constrained environments.
Multimodal Sentiment Analysis Based on Cross-Modal Attention and Gated Cyclic Hierarchical Fusion Networks

Multimodal sentiment analysis has been an active subfield in natural language processing. This makes multimodal sentiment tasks challenging due to the use of different sources for predicting a speaker's sentiment. Previous research has focused on extracting single contextual information within a modality and trying different modality fusion stages to improve prediction accuracy. However, a factor that may lead to poor model performance is that this does not consider the variability between modalities. Furthermore, existing fusion methods tend to extract the representational information of individual modalities before fusion. This ignores the critical role of intermodal interaction information for model prediction. This paper proposes a multimodal sentiment analysis method based on cross-modal attention and gated cyclic hierarchical fusion network MGHF. MGHF is based on the idea of distribution matching, which enables modalities to obtain representational information with a synergistic effect on the overall sentiment orientation in the temporal interaction phase. After that, we designed a gated cyclic hierarchical fusion network that takes text-based acoustic representation, text-based visual representation, and text representation as inputs and eliminates redundant information through a gating mechanism to achieve effective multimodal representation interaction fusion. Our extensive experiments on two publicly available and popular multimodal datasets show that MGHF has significant advantages over previous complex and robust baselines.
Effect of Dietary Supplementation of Choline from Different Sources on Performance and Economics of Commercial Broiler Chicken

An experiment was conducted to investigate the effect of dietary supplementation of choline from different sources on the performance and economics of commercial broiler chicken. Day old broiler chicks (Vencobb, n=216) were randomly distributed into nine experimental groups with four replicates of six birds each. The experimental groups (T1 to T9) were fed with diet containing choline chloride 60% @ 1000 g/ton, 750 g/ton, and 500 g/ton feed in T1 (Control), T2, and T3 ration. Similarly, herbal choline @ 1000 g/ton, 750 g/ton and 500 g/ton feed was given in T4,5,6 ration, and phosphatidylcholine @ 1000 g/ton 750 g/ton and 500 g/ton feed-in T7,8,9 ration, respectively. The trial was carried out in deep litter pen for 42 days. During the whole experiment, the mortality pattern of the birds was within the permissible limits and revealed no adverse effects of feeding choline from different sources in diet. The study results indicated that the supplementation of choline chloride 60% @1000 g/ton feed (Control group) showed higher body weight and body weight gain compared to other rations. Total feed consumption and feed conversion ratio of birds fed with treatment rations supplemented with different choline sources were at par among the rations. The return over feed cost was highest in broilers fed a diet with choline chloride 60 % @ 1000 g/ton feed.
Criteria for Diagnosis of Polycystic Ovary Syndrome during Adolescence: Literature Review

Polycystic ovary syndrome (PCOS) is one of the most common endocrine conditions in women. PCOS may be more challenging to diagnose during adolescence due to an overlap with the physiological events of puberty, which are part of the diagnostic criteria in adult women. This review focuses on the evidence available in relation to PCOS diagnostic criteria for adolescents. Adolescent PCOS should be diagnosed using two main criteria irregular -menstrual cycles (relative to number of years post-menarche) and hyperandrogenism (clinical and/or biochemical); after excluding other conditions that mimic PCOS. Accurate definitions of the two main criteria will decrease challenges/controversies with the diagnosis and provide timely diagnosis during adolescence to establish early management. Despite the attempts to create accurate diagnostic criteria and definitions, this review highlights the limited research in this area, especially in the follow up of adolescents presenting with one diagnostic feature that are called “at risk of PCOS”. Studies in adolescents continue to use the Rotterdam diagnostic criteria that uses pelvic ultrasound. This is inappropriate, because previous and emerging data that show many healthy adolescents have polycystic ovarian morphology in the early years post-menarche. In the future, anti-Müllerian hormone levels might help support PCOS diagnosis if adolescents meet two main criteria.
Profiles of achievement motivation and instructional dissent

ABSTRACT We integrated perspectives from achievement goal theory and expectancy-value theory to investigate how undergraduate students’ (N = 475) achievement motivation might influence their instructional dissent. A latent profile analysis of students’ achievement goals, performance self-efficacy, task value, and perceived cost revealed four distinct subgroups of students characterized by differences in their achievement motivation. Students between these latent profiles differed to some degree in their use of expressive and vengeful dissent but not rhetorical dissent. When examining instructor clarity as a triggering agent of dissent, lack of clarity was positively associated with all three types of instructional dissent; however, auxiliary moderation models revealed that latent profile membership did not moderate these effects. Our results suggest that although instructor clarity has similar effects on students’ instructional dissent—regardless of their latent profile membership—students still experience some differences in instructional dissent which can be explained by their achievement motivation profiles.
Spin covers of maximal compact subgroups of Kac–Moody groups and spin-extended Weyl groups

Abstract Let G be a split real Kac–Moody group of arbitrary type and let K be its maximal compact subgroup, i.e. the subgroup of elements fixed by a Cartan–Chevalley involution of G. We construct non-trivial spin covers of K, thus confirming a conjecture by Damour and Hillmann. For irreducible simply-laced diagrams and for all spherical diagrams these spin covers are two-fold central extensions of K. For more complicated irreducible diagrams these spin covers are central extensions by a finite 2-group of possibly larger cardinality. Our construction is amalgam-theoretic and makes use of the generalised spin representations of maximal compact subalgebras of split real Kac–Moody algebras studied by Hainke, Levy and the third author. Our spin covers contain what we call spin-extended Weyl groups which admit a presentation by generators and relations obtained from the one for extended Weyl groups by relaxing the condition on the generators so that only their eighth powers are required to be trivial.
Spiders feeding on vertebrates is more common and widespread than previously thought, geographically and taxonomically

Abstract. According to a recent global literature survey, a total of 39 out of the 129 known spider families (∼30%) contain species capable of capturing vertebrate prey. The finding that the percentage of spider families engaged in vertebrate predation is so high is novel. Two groups of vertebrate-eating spiders are distinguished: “habitual vertebrate-eaters” vs. “occasional vertebrate-eaters”. The habitual vertebrate-eaters comprise ten spider families (Araneidae, Atracidae, Ctenidae, Lycosidae, Nephilidae, Pisauridae, Theraphosidae, Theridiidae, Trechaleidae, and Sparassidae) to which can be attributed 91% of all reported vertebrate predation incidents. The habitual vertebrate-eaters have evolved prey-capture adaptations such as (1) sufficient physical strength coupled with large body size, (2) the use of potent venoms, and (3) the use of highly efficient prey-catching webs. By contrast, unexpected feeding on vertebrates by the occasional vertebrate-eaters (i.e., Actinopodidae, Agelenidae, Amaurobiidae, Anyphaenidae, Barychelidae, Clubionidae, Corinnidae, Ctenizidae, Cyrtaucheniidae, Deinopidae, Desidae, Dipluridae, Eresidae, Filistatidae, Gnaphosidae, Haplonoproctidae, Linyphiidae, Liocranidae, Miturgidae, Oxyopidae, Pholcidae, Porrhothelidae, Salticidae, Selenopidae, Sicariidae, Sparassidae, Tetragnathidae, and Thomisidae) might be considered as chance events that took place when a tiny vertebrate crossed the path of an opportunistic spider. For a few families (e.g., Idiopidae) their status as habitual or occasional vertebrate predators is still unclear. In conclusion, our survey unveiled a large number of spider taxa previously not anticipated to feed on vertebrate prey. These findings improve our general understanding of spider feeding ecology and provide a first assessment of the significance of vertebrate prey as a food source for spiders.
Diagnosis and serotyping of dengue using cost-effective high-resolution melting curve based real time PCR

Dengue virus (DENV) is classiﬁed into four serotypes: DENV-1, DENV-2, DENV-3, and DENV-4 which are genetically-related but antigenically distinct types. Although primary infection with a serotype of DENV gives lifelong immunity to that serotype, the secondary infection with other serotype leads to the development of dengue hemorrhagic fever and dengue shock syndrome. Serological tests that can detect NS1 antigen on the day one of illness is nonspecific and less sensitive to diagnose dengue in the first week of illness. IgM and IgG antibody detection may not be positive until the later part of first week. Hence it is necessary to develop a nucleic acid-based test kit for detection of DENV in the early phase of the disease such that the complications can be prevented. Simultaneous detection of serotype of DENV helps in understanding the epidemiology of the disease. In the present study, a single primer pair was designed to 3′ untranslated region of DENV genome. After amplification, the melting temperature (Tm) for DENV-1, DENV-2, DENV-3 and DENV-4 was found to be 83.96 ± 0.58 ˚C, 81.99± 0.26 ˚C, 84.54± 0.15 ˚C, and 83.28 ± 0.12 ˚C, respectively.
