PREVALENCE AND RISK FACTORS OF TOXOPLASMOSIS AMONG WOMEN OF REPRODUCTIVE AGE, SOUTHWESTERN IRAN

Toxoplasma gondii is an obligate intracellular parasite that has a worldwide prevalence. This infection can lead to severe problems during pregnancy, including miscarriage, and fetal develop-mental retardation. This study assessed the seroprevalence of toxoplasmosis in women of reproductive age in Dehdasht, Iran. Blood samples were collected from 300 women referred to Health Center between Febr-uary and July 2020. Serum was separated and the anti- Toxoplasma IgG & IgM were assessed by using the ELISA. Also, all women were administered a questionnaire to record demographic and risk factors data such as age, residence, education level, marital status, contact with cats, consumption of raw vegetables, methods of cooking meat, occupation, raw liver consumption, contact with soil, and raw egg consumption. SPSS software v.23 and Chi-square test used for statistical analyses. The results showed that 32/300 (10.6%) women were seropositive for anti- Toxoplasma IgG, but negative for anti- Toxoplasma IgM. There was a significant relationship between the prevalence of toxoplasmosis with age, accommodation, contact with cats, and methods of washing vegetables, number of serving vegetables per day, method of cooking meat, occupation, liver consumption, and contact with soil. There was no significant relationship between toxoplasmosis with marital status, consumption of raw vegetables, number of servings of meat, and consumption of eggs.
Generation of electric-field-induced anti-Stokes Raman scattering in the visible region (E-CARSv) from nitrogen in air

Electric-field-induced anti-Stokes Raman scattering in the visible region (E-CARSv) is a third-order nonlinear optical effect used for measuring electric field sensitively, especially at atmospheric or higher pressure. This study demonstrated E-CARSv generation from nitrogen molecules using a visible laser at 532 nm, a tunable infrared laser at approximately 4.3 μm, and an applied DC electric field. The results revealed that the square root of the signal intensity was proportional to the external electric field strength, which corresponded with the theoretical prediction. E-CARSv can be applied to a wide range of mediums containing nitrogen molecules, including plasmas generated in an open-air environment.
Enhanced radiation tolerance in nanocrystalline MgGa2O4

The authors demonstrate a substantial enhancement in radiation-induced amorphization resistance for single-phased nanocrystalline (NC) versus large-grained polycrystalline MgGa2O4. NC and large-grained MgGa2O4 were irradiated at ∼100K with 300keV Kr++ ions to fluences ranging between 5×1019 and 4×1020Kr∕m2. Large-grained MgGa2O4 samples began to amorphize by a fluence of 5×1019Kr∕m2, while NC MgGa2O4 remained crystalline with no evidence for structural changes (other than moderate grain growth in the lowermost implanted region), to a fluence of 4×1020Kr∕m2. To our knowledge, this is the first experimental study to reveal enhanced amorphization resistance in an irradiated, single-phase, NC material.
Mapping Class Groups, Homology and Finite Covers of Surfaces

Let S be an orientable surface of genus g with n punctures, such that χ(S) = 2 − 2g − n < 0. Let ψ ∈ Mod(S) denote an element in its mapping class group. In this thesis, we study the action of ψ on H1( S, C), where S varies over the finite covers of S to which ψ lifts. We first show that if ψ is a nontrivial mapping class then there exists a finite cover S such that each lift of ψ to S acts nontrivially on H1( S, C). We then show that the combination of the lifted actions of ψ and the Galois groups of the covers on H1( S, C) can be used to determine the Nielsen–Thurston class of ψ. We then turn to the following conjecture: that for each pseudo-Anosov mapping class ψ, there exists a lift ψ to a finite cover whose action on H1( S, C) has spectral radius strictly greater than one. We show that the conjecture holds if and only if the mapping torus Tψ has exponential growth of torsion homology with respect to a particular collection of finite covers. We use growth of torsion homology to characterize the mapping classes for which the conjecture holds. Then, we show that if the conjecture fails then Tψ is large.
Oscillatory solitary waves in a resonant system between long gravity and short capillary waves

Oscillatory solitary waves are analytically examined in a resonant system between long gravity and short capillary waves. Applying the procedure of the normal form analysis to the interaction equation for steady state, weakly nonlinear amplitude equations are derived. Solitary wave solutions of the equations are shown to be in good agreement with numerical results in both long and short wave modes, as far as the wave amplitudes are small. Integrability of the interaction system is briefly discussed in the parameter region where the solutions exist.

Metasurfaces for Sensing Applications: Gas, Bio and Chemical

Performance of photonic devices critically depends upon their efficiency on controlling the flow of light therein. In the recent past, the implementation of plasmonics, two-dimensional (2D) materials and metamaterials for enhanced light-matter interaction (through concepts such as sub-wavelength light confinement and dynamic wavefront shape manipulation) led to diverse applications belonging to spectroscopy, imaging and optical sensing etc. While 2D materials such as graphene, MoS2 etc., are still being explored in optical sensing in last few years, the application of plasmonics and metamaterials is limited owing to the involvement of noble metals having a constant electron density. The capability of competently controlling the electron density of noble metals is very limited. Further, due to absorption characteristics of metals, the plasmonic and metamaterial devices suffer from large optical loss. Hence, the photonic devices (sensors, in particular) require that an efficient dynamic control of light at nanoscale through field (electric or optical) variation using substitute low-loss materials. One such option may be plasmonic metasurfaces. Metasurfaces are arrays of optical antenna-like anisotropic structures (sub-wavelength size), which are designated to control the amplitude and phase of reflected, scattered and transmitted components of incident light radiation. The present review put forth recent development on metamaterial and metastructure-based various sensors.
An isothermal etchback‐regrowth method for high‐efficiency Ga1−xAlxAs‐GaAs solar cells

High‐efficiency p‐Ga1−xAlxAs, p‐GaAs, n‐GaAs solar cells are made by isothermally soaking n‐GaAs substrates in an undersaturated Zn‐doped Ga‐Al‐As melt. This one‐step growth procedure produces a graded band gap p‐Ga1−xAlxAs layer 0.2–0.4 μm thick. Efficiencies of 18.5% AM0 and 21.9% AM1 have been measured.
Optimal Dosing of Breast Cancer Chemotherapy using Robust MPC Based on Linear Matrix Inequalities

In this paper, we consider an application of robust model predictive control to optimal dosing of breast cancer chemotherapy. The model-patient mismatch is handled by computing an ellipsoidal invariant set containing the measured patient’s states at each sampling time. An optimal dose of chemotherapeutic agent is obtained by solving a convex optimization problem subject to linear matrix inequalities. In the case study of simulated patients, the results show that the tumor volume can be reduced to a specified target with up to 30% model-patient mismatch. Moreover, the robust model predictive control algorithm can achieve better treatment results as compared with the nonlinear model predictive control algorithm while the on-line computational time is significantly reduced.
INTERRELATIONSHIP BETWEEN MIXED RUMEN BACTERIA AND PROTOZOA ON THE IN VITRO DEGRADATION OF PROTEIN

An in vitro study was conducted to examine the degradation of various protein sources by mixed rumen bacteria, mixed rumen protozoa and a combination of bacteria and protozoa. Rumen microorganisms were isolated from the rumen of sheep fed a concentrate mixture and hay. Microbial suspensions were anaerobically incubated at 39°C for 12 h. The results revealed that, mixed rumen bacteria always produced more ammonia than mixed rumen protozoa. Heated soybean meal was deaminated at a faster rate (P<0.05) than that of soluble casein, insolube casein and killed bacteria by bacteria. However, protozoa deaminated killed bacteria at a faster rate (P<0.05) than that of soluble casein, insolube casein and heated soybean meal. Nonammonia-nonprotein N was greater (P<0.05) with protozoa than bacteria. When incubations containing bacteria or protozoa were compared with the combination of bacteria and protozoa, the combination always caused a synergistic increase in ammonia and decrease in nonammonia-nonprotein N (P<0.05). It could be concluded that there is synergism between rumen bacteria and protozoa on the degradation of protein. ,
FULL-TEXT SEARCH FOR THAI INFORMATION RETRIEVAL SYSTEMS

While there have been a lot of efficient full-text search algorithms developed for English documents, these algorithms can be directly used for other languages, e.g. Chinese, Japanese, Thai and so on. However, due to idiosyncrasies of each individual language, directly applying such algorithms may not be suitable for the language considered. This paper proposes a simplification of Boyer-Moore algorithm, called BMT, in order to reduce computation and makes it appropriate for Thai full-text. To investigate the efficiency, the comparison of BMT with other search algorithms is evaluated. Moreover, we applied syllable-like segmentation, called Thai character clusters (TCCs), to improve searching efficiency in Thai documents by grouping Thai characters into inseparable units. The TCC is based on the spell features of Thai language. Comparing with traditional full-text searching methods, this approach can improve not only searching time and memory consumption but also searching accuracy. The experimental results evidence that searching methods using TCC outperform the traditional methods in full-text search algorithm.
Controlled Probability Proportional to Size Sampling Designs.

Abstract : Any sampling design, d, of size n without replacement based on a finite population u of N units or strata can be formally presented by a pair (s sub d, P sub d), where S sub d called the support of d is any set of subsets of size n each based on the elements of u such that the (set theoretic) union of these subsets, called samples, is u and P sub d is a strictly positive probability distribution on S sub d. A sampling design is said to be a probability proportional to size, denoted by PPS(N,n), if the probability that the unit i is being selected in a random sample is proportional to a known positive quantity associated with the unit i = 1,2,. ,N. The literature of survey sampling offers a PPS(N,n) with S sub d consists of all (N over n) possible samples. Here we give an easily applicable technique for the construction of PPS(N,n) with various support sizes and various probabilities on each support. Such sampling designs are needed for controlled samplings when some samples are undesirable to be chosen or we need to minimize (or maximize) the probabilities of the selection of certain samples.

Electroluminescence measurement of InAlAs/InGaAs HEMTs lattice-matched to InP substrates

InAlAs/InGaAs HEMTs latticed-matched to InP substrates are promising devices for high-speed application owing to their excellent high-frequency performances. Their low breakdown voltage and the appearance of a kink, however, limit their application to practical circuits. The impact ionization at the drain edge in the channel has been pointed out as the origin of these phenomena. Several authors have used electroluminescence (EL) from FETs composed of compound semiconductors to investigate the impact ionization in their channels. For InGaAs-based FETs, EL with energy far higher than the band gap of the channel has been already investigated. In this paper, we report measurements of the EL appearing from the top of the InAlAs/InGaAs HEMTs for energy lower than 1 eV at room temperature. We mainly discuss the carrier temperature extracted from the spectrum and the spatial distribution of the intensity. We also report the EL appearing from the cleaved side of the FET channel.

Research on Image Style Convolution Neural Network Migration Based on Deep Hybrid Generation Model

: The main content of image style transfer transforms the image style from one region to another. This task puts forward new needs for the traditional convolutional neural network architecture. Therefore, a deep hybrid generation model is usually used in the study of processing image style transfer. Image style transfer aims to transform the image into a new idea by image generation. This paper proposes an image-style convolution neural network migration model based on the deep mixing generation model based on background. The image quality is improved through image processing. The deep hybrid generation model mainly relies on to combine confrontation network generation and self-encoder. In this paper, unsupervised and supervised image style migrations are designed according to the different basic tasks of image style migration. On this basis, unsupervised image style migration of combative neural networks based on cyclic consistency and supervised image style migration of adversarial networks based on cross-domain self-encoder are proposed. This paper further improves the quality of created images by introducing an unsupervised and supervised image style migration standard dataset.
C‐/Ka‐band circularly polarized shared‐aperture antenna array

A C‐/Ka‐band circularly polarized (CP) shared‐aperture scanning antenna array has been proposed in this paper. Here, the antenna array working in the C‐band (6.48–6.52 GHz) is composed of 4 × 4 cross‐dipole antenna elements, and each cross‐dipole antenna element is fed by a 1‐to‐2 power divider with 90° phase difference, so that it can induce left/right‐hand CP wave. As for the antenna array working in the Ka‐band (27.5–28.5 GHz), it is made up of 16 × 16 CP antenna elements, in which each CP antenna element is an aperture‐coupled chamfered patch fed by substrate integrated waveguide (SIW) structure. To realize the proposed scanning array, the C‐band antenna array is set within the gap between adjacent antenna elements of the Ka‐band antenna array, and the radiation apertures of all the antenna elements are printed on the same plane. Notably, such a layout can yield good isolation performance between the C‐band antenna and the Ka‐band antenna element. From the measured results, in the C‐band, the proposed scanning array can achieve a beam scanning range of 0°–38° with axial ratio (AR) < 3 dB, a port isolation of greater than 45 dB, and a maximum gain of 18.2 dBic. On the other hand, in the Ka‐band, the proposed scanning array can yield a beam scanning range of 0°–45° with AR <3 dB, a port isolation of greater than 37 dB, and a maximum gain of 26.2 dB.
Looking into the IL-1 of the storm: Are inflammasomes the link between immunothrombosis and hyperinflammation in cytokine storm syndromes?

Inflammasomes and the interleukin (IL)-1 family of cytokines are key mediators of both inflammation and immunothrombosis. Inflammasomes are responsible for the release of the pro-inflammatory cytokines IL-1β and IL-18, as well as releasing tissue factor (TF), a pivotal initiator of the extrinsic coagulation cascade. Uncontrolled production of inflammatory cytokines results in what is known as a “cytokine storm” leading to hyperinflammatory disease. Cytokine storms can complicate a variety of diseases and results in hypercytokinemia, coagulopathies, tissue damage, multi-organ failure and death. Patients presenting with cytokine storm syndromes have a high mortality rate, driven in part by disseminated intravascular coagulation (DIC). Whilst our knowledge on the factors propagating cytokine storms is increasing, how cytokine storm influences DIC remains unknown, and therefore treatments for diseases, where these aspects are a key feature are limited, with most targeting specific cytokines. Currently, no therapies target the immunothrombosis aspect of hyperinflammatory syndromes. Here we discuss how targeting the inflammasome and pyroptosis may be a novel therapeutic strategy for the treatment of hyperinflammation and its associated pathologies.
Pollen analytical study of late-Holocene sediments from Trans-Yamuna segment of Western Doon valley of Northwest Himalaya

A trench across a Quaternary fault in a berm was dug out at Sirmuri Tal in the Trans- Yamuna segment of Western Doon valley in Himachal Pradesh. Pollen analytical investigation of 4.90 m deep trench profile from Sirmuri Tal has shown that between 2800 to l800 years BP, mixed open vegetation comprising chiefly grasses, sedges, Cheno/Am, Artemisia and Ranunculaceae together with sparsely distributed trees viz., Emblica officinalis, Shorea robusta, Holoptelea, Mallotus, Grewia, Meliaceae, etc. grew in the region under dry climatic regime. The lake did exist, but it was small in dimension as indicated by the meagre presence of aquatic taxa such as Typha and Potamogeton. Subsequently, between 1800 to 400 years BP, mixed deciduous forests were established as reflected by the improvement in Emblica officinalis, Mallows, Grewia, etc. as well as invasion of Terminalia, Adina cordifolia, Acacia and Syzygium in the region. The overall increased diversity in the forest floristics signifies that the moist climatic condition prevailed in the region during this period. Lake became wider in expanse as implied by the improved frequencies of Potamogeton and Typha and first encounter of Dinoflagellate cysts in good number. Since 400 years BP and onwards, the climate deteriorated as evidenced from the decline in the vegetation cover. The lake transformed into a swamp as evidenced by the increase in sedges and Chen/Am and a simultaneous decline in aquatic vegetation. The excessively high frequencies of Pinus pollen denote its transportation by wind and water from nearby subtropical belt where chirpine forests occur luxuriantly.
A continuous-wave Fe{sup 2+}:ZnSe laser

A continuous-wave oscillation is obtained for the first time in a Fe{sup 2+}:ZnSe laser. The laser wavelength was in the range from 4.04 to 4.08 {mu}m. A liquid-nitrogen-cooled active element was pumped by a Cr{sup 2+}:CdSe laser at 2.97 {mu}m. The maximum output power of the laser was 160 mW with the 56% slope efficiency. The minimum absorbed pump power threshold was 18 mW. The intrinsic losses in the Fe{sup 2+}:ZnSe crystal did not exceed 0.024 cm{sup -1} during lasing. (lasers. amplifiers)
Ibex: Privacy-preserving Ad Conversion Tracking and Bidding

This paper introduces Ibex, an advertising system that reduces the amount of data that is collected on users while still allowing advertisers to bid on real-time ad auctions and measure the effectiveness of their ad campaigns. Specifically, Ibex addresses an issue in recent proposals such as Google's Privacy Sandbox Topics API in which browsers send information about topics that are of interest to a user to advertisers and demand-side platforms (DSPs). DSPs use this information to (1) determine how much to bid on the auction for a user who is interested in particular topics, and (2) measure how well their ad campaign does for a given audience (i.e., measure conversions). While Topics and related proposals reduce the amount of user information that is exposed, they still reveal user preferences. In Ibex, browsers send user information in an encrypted form that still allows DSPs and advertisers to measure conversions, compute aggregate statistics such as histograms about users and their interests, and obliviously bid on auctions without learning for whom they are bidding. Our implementation of Ibex shows that creating histograms is 1. -2.5× more expensive for browsers than disclosing user information, and Ibex's oblivious bidding protocol can finish auctions within 550 ms. We think this makes Ibex capable of preserving a good experience while improving user privacy.
New sports and no spectators: Japan’s performance at the Tokyo 2020 Olympic Games

ABSTRACT Rationale: This paper examines Japan’s performance at the Tokyo 2020 Olympic Games and considers whether the inclusion of new sports and the Games being staged behind closed doors influenced Japan's performance as the host nation. Approach: We analysed Japan’s medal output and ranking at Tokyo 2020 in the context of its historical Summer Olympic performances and compared with other recent hosts. We also analysed how Japan’s performance changed between Rio 2016 and Tokyo 2020 in different events (men, women and mixed) and in different sports. Findings: Japan improved its performance at its home Games across multiple measures. Evidence of improvement between Rio 2016 and Tokyo 2020 was seen in men’s, women’s and mixed events and across the portfolio of sports that were common to both editions. Japan’s home performance was amplified by its success in the new sports added to the programme. Practical implications: To promote fair competition, the inclusion of new sports at future Games should be evaluated on the basis of their global appeal alongside their local popularity within the host nation. Research contribution: Our findings somewhat challenge conventional wisdom that home crowd support is a key game location factor which contributes to home advantage.
