Bioelectricity in Developmental Patterning and Size Control: Evidence and Genetically Encoded Tools in the Zebrafish Model

Developmental patterning is essential for regulating cellular events such as axial patterning, segmentation, tissue formation, and organ size determination during embryogenesis. Understanding the patterning mechanisms remains a central challenge and fundamental interest in developmental biology. Ion-channel-regulated bioelectric signals have emerged as a player of the patterning mechanism, which may interact with morphogens. Evidence from multiple model organisms reveals the roles of bioelectricity in embryonic development, regeneration, and cancers. The Zebrafish model is the second most used vertebrate model, next to the mouse model. The zebrafish model has great potential for elucidating the functions of bioelectricity due to many advantages such as external development, transparent early embryogenesis, and tractable genetics. Here, we review genetic evidence from zebrafish mutants with fin-size and pigment changes related to ion channels and bioelectricity. In addition, we review the cell membrane voltage reporting and chemogenetic tools that have already been used or have great potential to be implemented in zebrafish models. Finally, new perspectives and opportunities for bioelectricity research with zebrafish are discussed.
Modified Method of Generating Randomized Latin Squares

In combinatorics and in experimental design, Latin square (LS) plays a vital role. It has been studied for centuries and especially used in statistics. Let L(n) be the number of Latin square of order n . L(n) increases exponentially as n increases. The feasible solutions of three dimensional planar assignment problem (3DPAP) are latin squares. The 3DPAP and related problems are NP hard. Hence to solve these problems using genetic algorithms, randomly creating a Latin square method is essential. O’Carroll has given a method for random generation of Latin square. The method however fails occasionally. So we have given a modified method and this modified method is efficient in the generation of random Latin square.
A geometrical optics model based on the non-Gaussian probability density distribution of sea surface slopes for wind speed retrieval at low incidence angles

ABSTRACT In this study, a large amount of data from precipitation radar (PR) and National Data Buoy Center (NDBC) buoys are collocated for the development and validation of a Geometrical Optics Model, in order to retrieve wind speed at small incidence angles. The omni-directional model is developed based on the combination of the quasi-specular scattering theory and non-Gaussian probability density distribution of ocean surface slope, and can be applied at incidence angles as high as 15°. There are four parameters included in the proposed model: the effective Fresnel reflection coefficient, the mean square slope, and the two coefficients associated with the kurtosis of the sea surface slope distribution. Using one half of the collocated data, the dependence of the four parameters on the in situ wind speed is acquired. The results show that the effective Fresnel reflection coefficient has a decrease relative to that obtained in previous studies. We combine the proposed model with the maximum-likelihood estimation (MLE) technique to retrieve the ocean surface wind speed at the 10 m height. The retrieved wind speeds are then validated against those measured by the NDBC buoys. The comparison shows that the root mean square error (RMSE) and bias between the model retrievals and buoy observations are 1.54 m s–1 and 0.1 m s–1, respectively, revealing high agreements in the wind speed estimations. The results of this study indicate that the proposed model and the PR measurements at low incidence angles can provide reasonably accurate estimates of the surface wind speeds within the range of 0–20 m s–1.
MALDI-TOF MS Indirect Beta-Lactamase Detection in Ampicillin-Resistant Haemophilus influenzae

Rapid identification of beta-lactamase-producing strains of Haemophilus influenzae plays key role in diagnostics in clinical microbiology. Therefore, the aim of this study was the rapid determination of beta-lactamase’s presence in H. influenzae isolates via indirect detection of degradation ampicillin products using MALDI-TOF MS. H. influenzae isolates were subjected to antibiotic resistance testing using disk diffusion and MIC methodologies. Beta-lactamase activity was tested using MALDI-TOF MS, and results were compared to spectral analysis of alkaline hydrolysis. Resistant and susceptible strains of H. influenzae were distinguished, and strains with a high MIC level were identified as beta-lactamase-producing. Results indicate that MALDI-TOF mass spectrometry is also suitable for the rapid identification of beta-lactamase-producing H. influenzae. This observation and confirmation can accelerate identification of beta-lactamase strains of H. influenzae in clinical microbiology, which can have an impact on health in general.
A comprehensive survey on QoS for video transmission in heterogeneous mobile ad hoc network

Major challenging issue in H‐MANETs (Heterogeneous Mobile Ad hoc Networks) is video transmission because it gets affected due to various factors like dynamic change in topology, interference, node mobility, collusion, and so on. Periodic connection is caused by the topology dynamic change, which leads to significant packet loss. Advancements provide the technical basis for video streaming over H‐MANETs in wireless networking and mobile devices. And efforts to achieve video transmission via H‐MANETs have run into some barriers, which have been overcome in various ways. Nonetheless, H‐MANETs are essential to provide video transmission certainty and quality provisioning. Due to the limited resources, the unreliability of wireless links, node mobility, and heterogeneity, establishing video streaming or enabling real‐time multimedia applications over H‐MANET with acceptable QoS (quality of service) poses several issues. The article's main goal is to survey QoS‐based video transmission in H‐MANETs. This study discusses the video transmission method in H‐MANET and the importance of the QoS that may be used for video transmission in H‐MANET. Various routing protocols and existing methodologies to improve QoS for video transmission in H‐MANET are discussed. In addition, the impact of delay in video transmission over H‐MANET has been discussed. Several obstacles and issues have been highlighted in providing QoS for video transmission in H‐MANET. From 2013 to 2021, a systematic literature review (SLR) is done for QoS‐based video transmission in the H‐MANET. This survey systematically gives the technical direction for research on QoS‐based video transmission and discusses potential future aspects.
Adaptive Synchronization in Unknown Stochastic Chaotic Neural Networks with Mixed Time-Varying Delays

It is widely believed that chaos synchronization has played a more and more significant role in nonlinear science (Chen & Dong, 1998; Pecora & Carroll, 1990; Tang & Fang, 2008; Tang et al, 2008; Tang et al, 2009a; Tang et al, 2009b; Tang et al, 2009c; Ojalvo & Roy, 2001; Yang & Chua, 1997; Boccaletti et al, 2002; Shahverdiev et al, 2002). Since Pecora and Carroll (Pecora & Carroll, 1990) synchronized two identical systems with different initial conditions, chaos synchronization has drawn much attention ABSTRACT
COMPARATIVE ANALYSIS OF SCALAR AND VECTOR CONTROL INDUCTION MACHINE DRIVE THROUGH MODELING AND SIMULATION

This paper presents scalar & vector control of three phase induction motor. Scalar control as the name indicates is due to magnitude variation of control variable only disregards any coupling effect in the machine. The scalar control is very simple method for controlling the speed of induction motor compared to the vector control which is more complex. Vector control is completely mathematical equations based model on control of torque and speed of a three-phase indirect vector controlled VSI fed cage induction motor drive that is controlled through the pulse width modulation. Finally comprise the result of scalar and vector control technique.
Evaluating the Critical Period Influence on the Development of Semantic Radicals Awareness and Lexical Tones Awareness in Chinese Character Recognition

The present study adopts the priming word-judging paradigm to investigate whether the critical period will influence radical and lexical tone awareness during the bilinguals' Chinese character recognition. Two types of bilinguals (simultaneous and sequential bilinguals) will be recruited as participants in the present study. The different features between these two types of participants are used to test the influence of the critical period. Through a Chinese character decision task experiment, we hypothesis that the critical period will influence the semantic radical and lexical tone awareness while processing the Chinese characters of bilinguals. In addition, this study will provide some advice to learning Chinese characters in second language acquisition.

Research on Fan Identity of Chinese Entertainment Industry in the New Media Era

With the development of the entertainment industry, China's fan economy is becoming an integral part of the popular culture and entertainment economy. The current Chinese fan economy and entertainment market is traffic-driven, with fans organizing support activities on Internet and new media platforms, forming a extremely unique fan culture phenomenon in the world. This paper attempts to study the construction of fan identity and its influence in the new media era, using methods such as qualitative and quantitative research to set up questionnaires and in-depth interviews. The research results found that in the construction of fan identity, it can be divided into three parts of idol-making participation, emotional connection and group identity for in-depth analysis, which involves fan behaviors such as fan consumption, text poaching and organizing support activities. Among them, continuous investment and the formation of fan group rules are important features. As for the influence of fan identity construction, the research explains it in terms of both positive and negative influences, include the impact on individual fans and the impact on the social level. The construction of fan identity not only brings positive development and positive emotional value to fans at the individual level, but also promotes the development of related industries in the social aspect. However, negative effects, such as the lack of individual rationality and the occupation of public resources, can not be ignored and require the joint efforts of the government, platforms, idols and fans to make fan culture develop in a healthy way.
Dietary Supplementation with Linseed Oil Ethyl Esters Improves Sexual Behavior and Chosen Seminal Parameters in Porcine Species

Simple Summary The work concerns upon the supplementation of linseed oil ethyl esters to boars in order to improve semen parameters. The study included two groups of animals each with n = 6 animals. The application of linseed oil ethyl esters at 3% to the complete feed mixture in the experimental group improved semen parameters. It significantly increased semen parameters in particular sperm viability (p < 0.001), higher semen volume (310 mL versus 216 mL, p < 0.001) and sperm concentration (331 versus 216 million per mL, p < 0.001). Higher semen quality parameters of normospermic boars may have a direct translation into prolonged use of animals, which will significantly reduce pig production costs. Abstract Numerous studies have shown that improvements in the sperm and semen quality of males of many species can be achieved with appropriate dietary supplements added to feed or fodder. Particularly promising seems to be the inclusion of omega polyunsaturated fatty acids in the diets of males. Among other things, it has been shown that linseed oil ethyl esters (EELO can be an excellent source of omega 3 polyunsaturated fatty acids in animal diets. These compounds are more durable and resistant to oxidation, epoxidation and resinification processes, and do not exhibit toxic properties in living organisms. At present, there is a lack of data in the literature on the enrichment of boar diets with EELO. The purpose of this study was to analyze the effects of the addition of EELO to boar diets on the properties of sperm in fresh semen. The study was conducted during the summer on semen collected from 12 boars of the line 990. Linseed oil ethyl esters were administered in each feeding at a rate of 3.0% (45 mL each) in basal diets for each boar on a daily basis for 16 weeks. Ejaculates were collected manually by the gloved-hand technique, at one-week intervals for eight-week periods, from the eighth week onwards after the start of feeding. Eight ejaculates were collected from each boar, totaling 96 samples. The addition of EELO to the diets of boars caused an increase in sperm viability (p < 0.001), semen volume (310 mL versus 216 mL, p < 0.001) and sperm concentration (331 versus 216 million per mL, p < 0.001). Furthermore, in the experimental animals, there was a decrease in the percentage of spermatozoa exhibiting DNA fragmentation. The experimental boars also showed an increase in the percentage of gametes without apoptosis and capacitation and an increase in the percentage of viable spermatozoa not showing lipid peroxidation membranes. Consequently, EELO nutritional supplementation resulted in the improved quality of the fresh semen of boars.
Astronomical Forcing on Loess Deposition in the Junggar Basin Since the Late Pliocene

Deciphering dust outbreak frequency in inland Asia during the late Cenozoic is important for predicting future hydroclimate in the arid parts of China. Here, we present an eolian sedimentary sequence in the southern Junggar Basin over the past 3.5 Ma, Northwestern China. Our data provide a minimum age of 3.5 Ma for the Gurbantunggut Desert. Rb/Sr ratios exhibit prominent 405 Kyr eccentricity cycles throughout our record with weak expression 41 Kyr cycles. We interpret this cyclicity as resulting from a strong impact of the global carbon cycle on western China hydroclimate. By contrast, gamma‐ray intensity data displays significant 100‐ and 41‐Kyr cycles after 2.8 Ma, suggesting important variations of the input of westerly derived dust. Our results demonstrate that Westerly derived moisture supply and dust input into inland Asia respond differently to orbital forcing; they suggest that moisture supply and dust transport by the Westerlies are controlled by different drivers since 3.5 Ma.
Interstellar molecular abundances toward Omicron Persei.

Extensive scanning of the B1 III star o Per (V=3.79, EB-V=0.32 mag) has been done with the Copernicus telescope-spectrometer in an effort to determine column densities or meaningful upper limits for several molecules expected to be relatively abundant in H i regions of moderate density. The combination of radio H i, OH, and CO emission-line data with the optical absorption measurements indicates that o Per is embedded in the near edge of a dense molecular cloud, and that the material seen in front of the star must be close to it. Molecules detected in ultraviolet absorption are H$sub 2$, HD, CO, and possibly OH. The CO rotational temperature is 2.2 Kless than or equal toT/sub rot/less than or equal to3.8 K. The observed column densities and upper limits from Copernicus and ground-based data are compared with recent models for molecular formation in diffuse clouds. (AIP)

Dedicated to the memory of Armand Borel, with affection and admiration

Let G be a connected semisimple Lie group such that the associated symmetric space X is Hermitian and let g be the fundamental group of a compact orientable surface of genus g ≥ 2. We survey the study of maximal representations of g into G, that is the subset of Hom( g, G) characterized by the maximality of the Toledo invariant ((17) and (15)). Then we concentrate on the particular case G = Sp(2n, R), and we show that if ρ is any maximal representation then the image ρ( g) is a discrete, faithful realizations of g as a Kleinian group of complex motions in X with an associated Anosov system, and whose limit set in an appropriate compactification of X is a rectifiable circle.
On the application of averaging median filters in remote sensing

The application of averaging median filters to remote sensing has been investigated, and the results are presented with some discussion and recommendations. Averaging median filters can be considered as a subclass of the standard median filters. For image processing purposes, a two-dimensional window is first filtered by a number of average filters, and the final result of the averaging filters is equal to the median of the central pixel value and the averaging filter results. Applications of this averaging median filter to Landsat images are presented, and the results show that the fine details are preserved while attenuating the impulsing noise. >
GAMMA-CONVERGENCE RESULTS FOR SUPERCONDUCTING THIN FILMS WITH HOLES AND FOR GINZBURG-LANDAU MODELS FOR SUPERCONDUCTORS WITH NORMAL INCLUSIONS.

We study a Ginzburg–Landau model for an inhomogeneous superconductor in the singular limit as the Ginzburg–Landau parameter κ = 1/ →∞. The inhomogeneity is represented by a potential term V (u ) = 1 4 (a(x)−|u |), with a given smooth function a(x) which is assumed to become negative in finitely many smooth subdomains, the “normally included” regions. For hex = O(| ln |) we study the Gamma-limit of this inhomogeneous Ginzburg-Landau functional. The vanishing of a(x) near the inner boundaries imply that the associated operators are strictly but not uniformly elliptic, leading to many questions to be resolved near the boundaries of the normal regions. The method we use is an extension of many techniques including the product estimate from Sandier-Serfaty, Jacobian estimates from Jerrard-Soner and an appropriate Hodge decomposition adapted to our problem. To resolve these problems, we first study the Γ-limit in the simpler case when a(x) is varying but bounded below by a positive constant a0. Second, we consider singular limits of the three-dimensional Ginzburg-Landau functional for a superconductor with thin-film geometry, in a constant external magnetic field, where d(x) is the thickness of the thin film. The superconducting domain is multiply connected and has characteristic thickness on the scale > 0, and we consider the simultaneous limit as the thickness → 0 and the Ginzburg-Landau parameter κ→∞. We assume v that the applied field is strong (on the order of −1 in magnitude) in its components tangential to the film domain, and of order log κ in its dependence on κ. Finally, we study the Γ-limit of the inhomogeneous superconducting Ginzburg-Landau model with a(x) vanishing on the boundary of the normal regions.
The influence of Key Opinion Leaders attitudes toward Netizens on public opinion

With the rapid development of the Internet, opinion leaders play a very important role in the guidance of public opinion. Gender equality, epidemic prevention measures, and Environmentalism are all global public opinion topics that have attracted much attention in recent years. In the face of these hot topics, more and more opinion leaders speak enthusiastically and express their attitudes. This study uses Key Opinion Leadership theory and secondary communication theory to explore the impact of Key Opinion Leaders on the three public opinion topics of equal rights between men and women, epidemic prevention measures, and environmental issues. More and more ordinary people pay attention to these events, which are affected by the Key Opinion Leader's attitude and make a positive response. This study made a theoretical contribution that how to promote the harmony and stability of the network environment.
Intelligent Reflecting Surface Secure Backscatter Communication Without Eavesdropping CSI

This letter presents an intelligent reflecting surface secure backscatter communication system. In this system, an IRS, as a backscatter device, leverages the signals from a power beacon (PB) as carriers to send confidential messages to a legitimate user. Meanwhile, an eavesdropper with unknown channel state information (CSI) attempts to intercept the messages. A power minimization scheme using the block coordinate descent and the semidefinite program methods is developed to realize secure transmission. This scheme jointly optimizes the PB’s beamformer and the IRS’s reflection coefficient to elevate the secrecy rate. Simulation results demonstrate that the optimization scheme can achieve secure communication in the proposed system.
A Framework for Analyzing Stochastic Jumps in Finance based on Belief and Knowledge

We introduce a formal language IE that is a variant of the language PAL developed in [van Benthem 2011] by adding a belief operator and a common belief operator,specializing to stochastic analysis. A constant symbol in the language denotes a stochastic process so that we can represent several financial events as formulae in the language, which is expected to be clues of analyzing the moments that some stochastic jumps such as financial crises occur based on knowledge and belief of individuals or those shared within groups of individuals. In order to represent beliefs, we use sigma-complete Boolean algebras as generalized sigma-algebras. We use the representation for constructing a model in which the interpretations of the formulae written in the language IE reside. The model also uses some new categories for integrating several components appeared in the theory into one.
Electrical impact of line-edge roughness on sub-45-nm node standard cells

Since line-end roughness (LER) has been reported to be of the order of several nanometers and to not decrease as the device shrinks, it has evolved as a critical problem in sub-45-nm devices and may lead to serious device parameter fluctuations and performance limitations for future very large scale integration (VLSI) circuit applications. We present a new cell characterization methodology that uses the nonrectangular gate print images generated by lithography and etch simulations with the random LER variation. We systematically analyze the random LER by taking the impact on circuit performance due to LER variation into consideration. We observed that the saturation current, delay, and leakage current are highly affected by LER as the gate length becomes thinner. Results show that when the root mean square value of LER is 6 nm from its nominal line edge, the worst case saturation current, delay, and leakage current degradation are as much as 10.3% decrease, 12.4% increase, and 7× increase at a 45-nm-node standard cell. Meanwhile the current, delay, and leakage current degradation at a 32-nm-node cell are up to 19.0% decrease, 21.8% increase, and 4600× increase, respectively.
