Multifidelity Model Calibration in Structural Dynamics Using Stochastic Variational Inference on Manifolds

Bayesian techniques for engineering problems, which rely on Gaussian process (GP) regression, are known for their ability to quantify epistemic and aleatory uncertainties and for being data efficient. The mathematical elegance of applying these methods usually comes at a high computational cost when compared to deterministic and empirical Bayesian methods. Furthermore, using these methods becomes practically infeasible in scenarios characterized by a large number of inputs and thousands of training data. The focus of this work is on enhancing Gaussian process based metamodeling and model calibration tasks, when the size of the training datasets is significantly large. To achieve this goal, we employ a stochastic variational inference algorithm that enables rapid statistical learning of the calibration parameters and hyperparameter tuning, while retaining the rigor of Bayesian inference. The numerical performance of the algorithm is demonstrated on multiple metamodeling and model calibration problems with thousands of training data.
An argument for the origins of heterospory in aquatic environments

The bifid, grapnel-like processes and apical prominence (acrolamella) found in some heterosporous Middle-Late Devonian spores closely resemble to the bifid processes of acritarchs, dinoflagellates, and some Cretaceous - Recent heterosporous aquatic ferns and the lycopsid Isoetes. The spongy wall ultrastructure of Protobarinophyton pennsylvanicum and Barinophyton citrulliforme shows some similarities to the megaspore wall structure of Azolla, Salvinia, Isoetes and Marsilea. The difference between the microspore and megaspore wall structure seen in B. citrulliforme and P. pennsylvanicum is comparable to the difference found in megaspore and microspore wall structure of Azolla, Salvinia and Isoetes. As the spongy wall structure found in heterosporous aquatic ferns provides buoyancy in an aquatic environment, the same may have been true for Protobarinophyton and Barinophyton and we suggest they probably were aquatic in the dispersal of their spores. These genera are among the oldest heterosporous megaspores known and we suggest that the earliest line of heterospory evolution may be linked to aquatic dispersal of spores and outcrossing in their fertilization during the Middle Devonian. This paper is a review of relevant literature and information. We use these data to support our hypothesis that the reproduction of plants by heterospory has its origins in aquatic environments.
Direct CP Violation in Charmless Hadronic B-Meson Decays at the PEP-II Asymmetric B-Meson Factory

The study of the quark transition b {yields} s{bar s}s, which is a pure loop-level (''penguin'') process leading to several B-meson-decay final states, most notably {phi}K, is arguably the hottest topic in B-meson physics today. The reason is the sensitivity of the amplitudes and the CP-violating asymmetries in such processes to physics beyond the Standard Model. By performing these measurements, we improve our understanding of the phenomenon of combined-parity (CP) violation, which is believed to be responsible for the dominance of matter over antimatter in our Universe. Here, we present measurements of branching fractions and charge asymmetries in the decays B{sup +} {yields} {phi}K{sup +} and B{sup 0} {yields} {phi}K{sup 0} in a sample of approximately 89 million B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy B-meson Factory at SLAC. We determine {Beta}(B{sup +} {yields} {phi}K{sup +}) = (10.0{sub -0.8}{sup +0.9} {+-} 0.5) x 10{sup -6} and {Beta}(B{sup 0} {yields} {phi}K{sup 0}) = (8.4{sub -1.3}{sup +1.5} {+-} 0.5) x 10{sup -6}, where the first error is statistical and the second is systematic. Additionally, we measure the CP-violating charge asymmetry {Alpha}{sub CP}(B{sup {+-}} {yields} {phi}K{sup {+-}}) = 0.04 {+-} 0.09 {+-} 0.01, with a 90% confidence-level intervalmore » of [-0.10, 0.18], and set an upper limit on the CKM- and color-suppressed decay B{sup +} {yields} {phi}{pi}{sup +}, {Beta}(B{sup +} {yields} {phi}{pi}{sup +}) < 0.41 x 10{sup -6} (at the 90% confidence level). Our results are consistent with the Standard Model, which predicts {Alpha}{sub CP}(B{sup {+-}} {yields} {phi}K{sup {+-}}) {approx}< 1% and {Beta}(B {yields} {phi}{tau}) << 10{sup -7}. Since many models of physics beyond the Standard Model introduce additional loop diagrams with new heavy particles and new CP-violating phases that would contribute to these decays, potentially making {Alpha}{sub CP} (B{sup {+-}} {yields} {phi}K{sup {+-}}) and {Beta}(B {yields} {phi}{pi}) quite large, our results can be used to substantially constrain the parameter spaces of such models. « less
Nephrotic Syndrome – Different Risk of Venous Thromboembolism with Different Approaches to Justify Prophylactic Anticoagulation

All of the circumstances influencing any of the elements of Virchow’s Triad can increase the risk of venous thromboembolism. Assessing prothrombotic factors can sometimes be difficult. One of the examples of such a condition is nephrotic syndrome. In this condition at least two elements of Virchow’s triad are affected: physiological blood composition and the venous blood flow which is slowed down by the edema. Except for the cases mentioned in KDIGO (Kidney Disease: Improving Global Outcomes), the use of anticoagulant drugs in the prophylaxis of VTE (Venous Thromboembolism) in nephrotic syndrome seems unclear. Nevertheless, due to the increased risk of VTE, it is worth implementing mechanical anticoagulant prophylaxis, which can also improve the quality of life of patients by reducing swelling. The article analyzes the current knowledge on the field and gives some proposals with low bleeding risk.
UTILIZATION OF CARROT JUICE TO INHIBIT Listeria monocytogenes

The antibacterial effect of the carrot juice and the distillate of carrot juice, against two strains of Listeria monocytogenes ( Listeria monocytogenes Z 7 and Listeria monocytogenes B 4 ) were investigated ( in vitro ). Fresh minced meat was inoculated with L.m . B 4 at level of 3.52 log 10 CFU/g of minced meat. The inoculated samples were subjected to treat with 0.6% of carrot juice and stored at 4 and 24°C to study the effect of carrot juice on Listeria monocytogenes B 4 ( in vivo ). Psychrotrophic aerobic bacteria and pH of minced meat were determined during storage period at 4 and 24°C. The chemical composition of minced beef meat were also determined. Results revealed that the antimicrobial effect of carrot juice against Listeria monocytogenes ( L.m . Z 7 and L.m. B 4 ) increased with increasing concentration of carrot juice. The carrot juice was bacteriostatic at concentration of 0.4% (v/v) and was bacteriocidal above this concentration. There was a significant difference (P < 0.05) between the concentration of 0.5% and 0.6% (v/v), meanwhile there was no significant difference (P > 0.05) between the concentration of 0.6 and 0.7% (v/v) for both strains of L.m . used in this study. In contrast, the distillate of carrot juice did not show any antimicrobial effects against both strains of L.m . at the concentrations tested. Meat pH ranged from 6.11 (Freshness) to 7.41 (Frank spoilage). The increase in pH value during storage was more pronounced at 24°C than at 4°C. The treatment of minced meat with 0.6% carrot juice resulted in a reduction of the number of L.m . B 4 on minced meat from log 10 CFU/g = 3.52 to 1.55 after 5 days of storage at 4°C. After 1, 2, 3, 4 and 5 days of storage at 4°C, the number of L.m . on samples treated with 0.6% of carrot juice was significantly lower as compared with the number on control samples. Likewise the use of 0.6% carrot juice showed antimicrobial effect against L.m . on minced meat stored at 24°C. However the effect was more pronounced at 4°C than at 24°C. Minced meat stored at 4 and 24°C, showed shelf life of 4 days and 14 hr respectively. Followed by off odours on day 5 and at 15 hr respectively.
Nidianthus gen. nov. - A Caytonanthus - like pollen organ from the Triassic of Nidpur, M.P., India

Nidianthus indicus gen. et sp. nov. is a synangiate pollen organ represented by more than 30 detached specimens. The compressed synangia were isolated from the Nidpur beds by bulk maceration of the Triassic shale in HF. Each synangium is elongated, radially symmetrical, appearing four-winged with a short axial attachment at base possibly representing ultimate branchlet. The four elongated pollen sacs remain attached at the base of synangium but appearing attached or free in middle and apical regions leaving four gaps at the time of dehiscence. The apical region of each pollen sac is pointed and bent inward towards the centre of synangium. Each pollen sac dehisces by a longitudinal slit along the midline of inner face. The surface of pollen sacs shows longitudinal striations. Some specimens showed a quadrangular abscission scar at the base of synangium. Cuticle of pollen sac wall showed elongated, rectangular to polygonal cells seemingly arranged in longitudinal files. Anticlinal walls thin, obscure, straight or slightly waved. Cells become narrow towards the inner margin. Many cells of pollen sac wall showed median papilla bases and cells near the apical region showed cutinized unicellular hairs. Sometimes, remains of an inner, obscurely cellular, granular membrane possibly representing a tapetal layer could also be seen on inner side of pollen sac wall. Inside each pollen sac is a single mass of pollen-grains. Pollen-grains bisaccate, bladders hemispherical or obovate showing irregular surface reticulum, Nidianthus gen. nov. closely resembles the anther-like pollen organ Caytonanthus of Caytoniales.
Palynology of the Quilon beds of Kerala State in South India II - Pollen of Dicotyledons and discussion

This contribution deals with a systematic account of the dicotyledonous pollen recovered from the carbonaceous and calcareous clays of the Quilon Formation of Kerala and a critical analysis of the entire palynological data of this formation. In all, 54 genera encompassing 62 species have been recorded in this paper; of these 7 genera and 44 species are new. The genera abundantly represented are Verrucosisporites, Polypodiisporites, Retipilonapites, Couperipollis, Clavapalmaedites, Paravuripollis, Longapertites, Quilonipollenites, Palmaepollenites, Dicolpopollis, Retitricolpites, Retirescolpites, Foveotricolpites, Ctenolophonidites, Zonocostites, Heterocolpites, Marginipollis, Hippocrateaceaedites, Margocolporites, Sapotaceoidaepollenites, Talisiipites, Verrutriporites, Maculoporites, Myrcipites, Anacolosidites, Clavaperiporites and Ornatetradites. The abundant occurrence of Polypodiisporites, coupled with Pteridacidites, intrabaculisporis and Eximospora and in conjunction with Dicolpopollis (abundant), Cauveripollis, Maculoporites, Compositoipollenites, Hippocrateaceaedites, pollen-types of Caesalpiniaceae, Sapotaceae and Droseraceae supports Lower to Middle Miocene age assigned to these beds on faunal evidence. The palynoassemblage indicates a tropical humid type climate with plenty of rainfall. The presence of pollen types related to Barringtonia, Rhizophora, Lumnitzera, Nipa, lriartea, Calamus, Metroxylon, Araliaceae, Sapindaceae, Meliaceae and Droseraceae and the spores of Polypodiaceae and Schizaeaceae testifies to the prevalence of brackish water mangrove swamps along the coastal belt of Kerala.
The Limiting Spectral Measure for the Ensemble of Symmetric Period m--Circulant Matrices

Given an ensemble of N x N random matrices, the first question to ask is whether or not the empirical spectral measures of typical matrices converge to a limiting spectral measure as N tends to infinity. While this has been proved in many thin patterned ensembles sitting inside all real symmetric matrices, frequently there is no nice closed form expression for the limiting measure. Further, current theorems provide few pictures of transitions between ensembles. We consider the ensemble of symmetric period m--circulant matrices with entries i.i. d.r. v. These matrices have toroidal diagonals periodic of period m. We view m as a "dial" we can "turn" from the highly structured symmetric circulant matrices, whose limiting eigenvalue density is a Gaussian, to the ensemble of all real symmetric matrices, whose limiting eigenvalue density is a semi-circle. The limiting eigenvalue densities f_m show a visually stunning convergence to the semi-circle as m tends to infinity, which we prove. In contrast to most studies of patterned matrix ensembles, we find explicit closed form expressions for the densities. We prove that f_m is the product of a Gaussian and a certain even polynomial of degree 2m-2. The proof is by derivation of the moments from the eigenvalue trace formula. The new feature, which allows us to obtain closed form expressions, is converting the central combinatorial problem in the moment calculation into an equivalent counting problem in algebraic topology. The explicit formula is then obtained using topology (especially Euler characteristic), generating functions, and complex analysis.
CYCLIC ACTIVITY OF OESTRUS IN ZOMRI GOATS NATIVE TO SAUDI ARABIA

The main objective of this study was to investigate whether the local Zomri female goats are seasonal or continuous breeders. Reproductive cyclicity was determined endocrinologically in five postpubertal female goats . Blood samples were collected twice a week over a twelve months period for the measurement of plasma progesterone concentrations which were used to determine reproductive cyclicity. Results of this study suggest that Zomry female goats native to Saudi Arabia tend to have a long reproductive season which extend throughout most of the year with a temporary cessation during the hot months of May-August.
Ambient LoRa Backscatter System With Chirp Interval Modulation

Ambient LoRa backscatter enables battery-free wireless communication with long-range connectivity for the Internet of Things. However, current efforts mainly focus on symbol-level modulation, which trades considerable data rates for long backscatter ranges. To enhance the data rate, this paper presents and prototypes Pacim, which fully explores the potential of long-period LoRa chirps and conveys additional information by varying symbol lengths. Specifically, we propose the chirp interval modulation scheme that modulates multiple data bits in each time interval between two chirp-based anchor symbols. Moreover, we design a twin-chirp cancellation method at the receiver that eliminates the frequency discontinuity within anchor symbols, and propose a fine-grained detection algorithm to measure the arrival time of anchor symbols in the frequency domain. We further propose three reliable methods to improve transmission reliability and analyze the symbol error rate (SER) performance. We also build a hardware prototype and perform comprehensive evaluations. Our experiment results show that Pacim can achieve up to $8.6 \times $ throughput gain while keeping long-range, compared with the state-of-the-art ambient LoRa backscatter design.
Research and Implementation of Automatic Composition System Based on ACMN

: The use of artificial neural network to compose music is a new computer composition method proposed in recent years. The advantage of this method is that it can process large-scale data in a relatively short time, greatly reducing the preparation work before computer composition and improving composition efficiency. However, there are still many problems that have not made obvious breakthroughs. For example, the yield is low, and a considerable proportion of the generated works have no appreciation value. They are completely random patchwork of notes and chords in the time dimension; the music produced is not pleasant, the melody is too simple and so on. In order to make the songs generated by the composition system more in line with the rules of music theory, this paper proposes a music generation model ACMN (Actor-Critic Music Network) based on the policy gradient method, which is characterized by the combination of reinforcement learning technology and neural network. Experiments show that, compared with the composition model without reinforcement learning technology, the ACMN model has more outstanding performance in terms of repetition rate and pleasantness.
POTASSIUM APPLICATION TO THOMPSON SEEDLESS GRAPEVINES IN CLAY SOIL

Thompson Seedless grapevines grown in clay soil were used in this work to determine the amount of potassium to be added per feddan and the proper time for its application. Potassium was added as potassium sulphate (48% K 2 O) at 0, 50, 75, 100 and 125 Kg K 2 O/feddan. The assigned amount/treatment was divided into two or three parts applied in the first week of March, May and in August after harvesting. The application of potassium significantly increased K content in the leaf petioles during bloom, veraison and maturation stages. The highest values were in bloom stage than the other stages. Potassium increased N percentage in leaf blades and starch in the canes. Ca and Mg were decreased and P% was not affected. TSS, TSS/acidity, cluster weight and yield/vine were significantly increased, while acidity was significantly lowered by increasing K 2 O amount. The most effective treatment was 125 Kg K 2 O.
Fatigue Performance Prediction of RC Beams Based on Optimized Machine Learning Technology

The development of fatigue damage in reinforced concrete (RC) beams is affected by various factors such as repetitive loads and material properties, and there exists a complex nonlinear mapping relationship between their fatigue performance and each factor. To this end, a fatigue performance prediction model for RC beams was proposed based on the deep belief network (DBN) optimized by particle swarm optimization (PSO). The original database of fatigue loading tests was established by conducting fatigue loading tests on RC beams. The mid-span deflection, reinforcement strain, and concrete strain during fatigue loading of RC beams were predicted and evaluated. The fatigue performance prediction results of the RC beam based on the PSO-DBN model were compared with those of the single DBN model and the BP model. The models were evaluated using the R2 coefficient, mean absolute percentage error, mean absolute error, and root mean square error. The results showed that the fatigue performance prediction model of RC beams based on PSO-DBN is more accurate and efficient.
Effect of Dietary Supplementation of Probiotic Aspergillus niger on Performance and Cecal Microbiota in Hy-Line W-36 Laying Hens

Simple Summary The use of antibiotics as a growth promoter in food-producing animals has been restricted throughout the world. As a result, many antibiotic alternatives have been evaluated in the poultry industry. Aspergillus niger is one of the probiotics of fungal origin that has shown promising effects in broiler production; however, few studies have been conducted on laying hens. Therefore, this study investigated the role of Aspergillus niger on performance, egg quality, and cecal microbial load of pathogenic bacteria in laying hens. The results showed that supplementation of Probioist®, a product containing the probiotic Aspergillus niger, at a rate of 220 mg/kg of diet, improved egg production and Haugh unit, and numerically decreased the cecal microbial load of Clostridium perfringens, Salmonella spp. , and Escherichia coli. Abstract This study aimed to investigate the role of the probiotic Aspergillus niger on the production performance, egg quality, and cecal microbial load of Clostridium perfringens, Salmonella spp. , and Escherichia coli in Hy-Line W-36 laying hens. A total of 72, 45-week-old Hy-Line W-36 laying hens were randomly allocated to one of the three dietary treatments with six replicates, and each replicate had four individually caged laying hens (n = 6 and 4 hens/replicate). The hens in each treatment group were fed a corn and soybean meal diet (Control), a diet supplemented with bacitracin methylene disalicylate (BMD) at a rate of 495 mg/kg of feed (Positive Control), or a diet supplemented with Aspergillus niger (Probioist®) at a rate of 220 mg/kg of feed (Probiotic). Supplementing probiotics in the laying hen diet significantly increased egg production at weeks 3 and 6 compared with the Positive Control. Haugh unit, a measure of egg quality, was significantly higher in laying hens fed the probiotic diet compared with the Control or Positive Control at week 10. Furthermore, the Probiotic group had numerically lower cecal microbial loads of pathogenic bacteria (Clostridium perfringens, Salmonella spp., and Escherichia coli) compared with the Control and Positive Control groups. The results suggest that Aspergillus niger could be used as a probiotic to improve laying hen performance and egg quality.
Extraction of Soil Nutrients Using Mehlich-3 Reagent for Acid-Mineral Soils of Florida

Soil testing is a multistep process starting with the collection of a sample that adequately represents the area or field to be tested. Due to wide-ranging soil conditions across Florida and the United States, multiple soil test methods exist. During the 1970s, Florida along with several other southeastern US states adopted Mehlich-1 (M1) as the official extractant for acidic soils. The UF/IFAS Plant Nutrient Oversight Committee approved the change from M1 to M3 in 2010. Based on observations of the interpretations, the technical committee revised the M3 interpretation in March 2014. The new interpretations have been correlated with the M1 interpretations, as closely and realistically as possible, so the actual nutrient recommendations are not changed. This 7-page fact sheet was written by Rao Mylavarapu, Tom Obreza, Kelly Morgan, George Hochmuth, Vimala Nair, and Alan Wright, and published by the UF Department of Soil and Water Science, May 2014.

Post-Cretaceous record of larger foraminifera from the Shillong Plateau, India: an evidence of environmental recovery during Early Cenozoic

The Late and post-Cretaceous succession of larger benthic foraminifera and planktic microfossils from the Shillong Plateau indicates events of extinction and recovery of the biotic forms. These events are interpreted using a conceptual framework involving biological responses to environmental changes caused by eustatic and climatic variations. Stratigraphic distribution shows that the Late Maastrichtian larger benthic foraminiferal assemblage disappears earlier than the planktic microfossils at the boundary interval. After their last occurrence in the Upper Maastrichtian, the larger foraminifera reappears in the carbonates of the Lakadong Formation dated by Glomalveolina primaeva as the Thanetian (P4). The event of the first appearance of larger foraminifera in the Shillong Plateau correlates with zone P4. When compared with other Tethyan sections (e.g., Mediterranean) where they start occurring in the strata equivalent to zone P3b, the event of their reappearance appears to be slightly delayed in the studied section. The P3b zone is the interval marked by the onsetting of habitable conditions on shelves (oligotrophic environments) and is followed by an interval (the equivalent of the P4 zone) of extensive carbonate generation, during which highly diversified larger foraminiferal assemblages evolve and become widely distributed. The Shillong assemblage, therefore, marks the phase of "expanded oligotrophy" in which recovery of carbonate platform environments occurred on a large scale on shallow neritic shelves.
