The structure of giant elliptical galaxies in poor clusters of galaxies.

Detailed photographic surface photometry is presented of the nine first brightest galaxies in poor clusters suspected of being cD galaxies. The surface photometry is put on an absolute scale, using multiaperture photoelectric photometry. Oemler (1976) and de Vaucouleurs (1948) laws are fitted to the profiles to derive structural parameters, and the structural properties of the galaxies are compared with those of the cD galaxies in rich clusters studied by Oemler (1976) and those of normal ellipticals studied by Kormendy (1977). It is found that (1) the profiles of first brightest galaxies are well fitted by an r to the 1/4 power law over a range of more than nine magnitudes and down to the faintest light levels observed and (2) structural parameters characterizing only the central part of first brightest galaxies in poor and rich clusters, and excluding the envelope component in the case of rich clusters, smoothly extend properties exhibited by normal ellipticals. These observations are consistent with the idea that the central part of first brightest galaxies in both poor and rich clusters is made up by the mergers of smaller galaxies.
On centrality and rapidity dependences of transverse momentum spectra of negative pions in 12 C + 12 C collisions at 4.2 GeV/c per nucleon

The dependences of the experimental transverse momentum spectra of the negative pions, produced in minimum bias 12C + 12C collisions at a momentum of 4.2A GeV/c, on the collision centrality and the pion rapidity range were studied. To analyze quantitatively the change in the pt spectra of π- mesons with the changes of collision centrality and pion rapidity range, the extracted pt spectra were fitted by Hagedorn, Boltzmann, Simple Exponential and Gaussian functions. The values of the extracted spectral temperatures T1 and T2 were consistently larger for the pt spectra of π- mesons coming from midrapidity range as compared to those of the negative pions generated in the target and projectile fragmentation regions. The spectral temperatures T1 and T2 extracted from fitting the pt spectra of π- mesons in range pt = 0.1–1.2 GeV/c practically coincided with each other in peripheral, semicentral and central 12C + 12C collision events, and thus did not show any collision centrality dependence. However, the values.
Effect of calf purchase weight, serum IG level and feeding systems on the incidence of diarrhoea, respiratory disease and mortality

A survey was conducted on 5100 purchased male Friesian calves in the period of 1976 to 1985 to determine the effect of serum immunoglobulin (Ig) level (low 15 ZST units or high 15 ZST units), purchase weight (light 40 kg or heavy 40 kg) and feeding system (bucket or ad libitum) on the occurrence of diarrhea, respiratory disease and mortality in the period 1 to 49 days following purchase. In the low and high Ig categories the respective proportions were 0.21 and 0.14, 0.6 and 0.28, 0.11 and 0.03 for diarrhea, respiratory disease and mortality. The corresponding values for light and heavy calves were 0.26 and 0.14, 0.30 and 0.32, 0.09 and 0.04. Similarly for bucket and ad libitum calves the respective values were 0.15 and 0.17, 0.28 and 0.34, 0.05 and 0.06.
Development of analysis method of andrographolide from Andrographis paniculata using UPLC-PDA

Andrographis paniculata is an herbaceous plant belonging to the family Acanthaceae dan also known as the “King of Bitters”. It has been utilized as traditional medicines by the local people in India and Southeast Asia. Many studies have been reported regarding the pharmacological activities of A. paniculata and Andrographolide. Currently, in addition to compound isolation and bioactivity assays, validation of analysis method is also required. Validation is used to demonstrate that the method used is appropriate and the results are precise and accurate. The method used needs to be simple, concise, precise, accurate, and widely used. The analysis in this study was carried out using Ultra-Performance Liquid Chromatography because the instrument operates at high pressure. In addition, the system uses fine particles which can reduce column length as well as solvent and time consumption. This study aims to validate analytical methods in determining the contents of andrographolide in an A. paniculata Leaves. The analytical method was validated through a Waters Alliance UPLC System with photodiode array (PDA) detector. The A. paniculata extract and standard solutions of Andrographolide were analyzed using reverse-phase C18 column which was maintained at 40°C. A mobile phase of 0.1% formic acid in acetnotirile and 0.1% formic acid in water was used at flow rate of 0.3 mL/min to achieve gradient elution. The linearity of the andrographolide showed excellent results (R2= 0.9999) in the concentration range of 7.8–250.0 µg/mL. The LOD and LOQ values of andrographolide were 0.068 µg/mL and 0.205 µg/mL, respectively. The intra-day and inter-day relative standard deviation (RSD) and relative error (RE) accuracy values of andrographolide were <±15. The quantitative analysis found that A. paniculata extract contained 12.45 ±0.06 mg/g of Andrographolide. This developed UPLC-PDA method was proven to be precise, specific, sensitive, and accurate for routine quality assessment of raw material of Andrographis paniculata leaves content.
Modeling Mutagenicity Status of a Diverse Set of Chemical Compounds by Envelope Methods

Envelope models [1] provide a flexible setup for dimension reduction in multivariate data analysis. They can work in conjunction with multivariate linear regression to produce estimates with reduced variance, and envelope-reduced data can also be used for class prediction by linear discriminant analysis. In this project we apply envelope methods on a Chemometrics dataset to assess their performance in estimation and prediction.
Coded apertures allow high-energy x-ray phase contrast imaging with laboratory sources

This work analyzes the performance of the coded-aperture based x-ray phase contrast imaging approach, showing that it can be used at high x-ray energies with acceptable exposure times. Due to limitations in the used source, we show images acquired at tube voltages of up to 100 kVp, however, no intrinsic reason indicates that the method could not be extended to even higher energies. In particular, we show quantitative agreement between the contrast extracted from the experimental x-ray images and the theoretical one, determined by the behavior of the material’s refractive index as a function of energy. This proves that all energies in the used spectrum contribute to the image formation, and also that there are no additional factors affecting image contrast as the x-ray energy is increased. We also discuss the method flexibility by displaying and analyzing the first set of images obtained while varying the relative displacement between coded-aperture sets, which leads to image variations to some extent simi.
Detection of the CN Zeeman Effect in Molecular Clouds

Observations of the Zeeman effect in the 3 mm lines of CN have been carried out with the 30 m IRAM telescope toward seven dense molecular clouds. Detections were achieved toward the Orion Molecular Cloud 1 (OMC1), toward two cores in the DR21OH molecular cloud, and probably toward the M17SW molecular cloud. The line-of-sight magnetic field strengths inferred are Blos(OMC1)=-0.36±0.08, Blos(DR21OH1)=-0.36±0.10, Blos(DR21OH2)=-0.71±0.12, and Blos(M17SW)=-0.33±0.14 mG. The theoretical implications of these results are discussed.
Target-Based Anticancer Indole Derivatives for the Development of Anti-Glioblastoma Agents

Glioblastoma (GBM) is the most aggressive and frequent primary brain tumor, with a poor prognosis and the highest mortality rate. Currently, GBM therapy consists of surgical resection of the tumor, radiotherapy, and adjuvant chemotherapy with temozolomide. Consistently, there are poor treatment options and only modest anticancer efficacy is achieved; therefore, there is still a need for the development of new effective therapies for GBM. Indole is considered one of the most privileged scaffolds in heterocyclic chemistry, so it may serve as an effective probe for the development of new drug candidates against challenging diseases, including GBM. This review analyzes the therapeutic benefit and clinical development of novel indole-based derivatives investigated as promising anti-GBM agents. The existing indole-based compounds which are in the pre-clinical and clinical stages of development against GBM are reported, with particular reference to the most recent advances between 2013 and 2022. The main mechanisms of action underlying their anti-GBM efficacy, such as protein kinase, tubulin and p53 pathway inhibition, are also discussed. The final goal is to pave the way for medicinal chemists in the future design and development of novel effective indole-based anti-GBM agents.
The Structure of the Female Genital System of the Diving Beetle Scarodytes halensis (Fabricius, 1787) (Hydroporinae, Dytiscidae), and the Organization of the Spermatheca and the Spermathecal Gland Complex

Simple Summary The large group of Dytiscidae, with more than 4300 species, is characterized by an extreme variation in male and female genital apparatus, with Hydroporinae exhibiting the greatest variation. Important structures, such as the spermatheca and the spermathecal gland, show a variable configuration in the several taxa. In Scarodytes halensis, different from Stictonectes optatus, the two structures are fused in a single complex organ; each region of this complex, however, exhibits an epithelium with a quite different ultrastructure. The epithelium of the region corresponding to the spermathecal gland consists of secretory and duct-forming cells, while the region homologous to the spermatheca has a simple epithelium. Sc. halensis is also provided with a very long spermathecal duct connecting the bursa copulatrix to the complex organ. This duct shows an epithelium rich of microtubules and junctional structures to support the thick layer of muscles surrounding the duct. A short fertilization duct is present between the complex organ and the common oviduct. The different organization of the genital apparatus in the two species suggests the presence of a different reproductive strategy. Abstract The fine structure of the female reproductive organs of the diving beetle Scarodytes halensis has been described, with particular attention to the complex organization of the spermatheca and the spermathecal gland. These organs are fused in a single structure whose epithelium is involved in a quite different activity. The secretory cells of the spermathecal gland have a large extracellular cistern with secretions; duct-forming cells, by their efferent duct, transport the secretions up to the apical cell region where they are discharged into the gland lumen. On the contrary, the spermatheca, filled with sperm, has a quite simple epithelium, apparently not involved in secretory activity. The ultrastructure of the spermatheca is almost identical to that described in a closely related species Stictonectes optatus. Sc. halensis has a long spermathecal duct connecting the bursa copulatrix to the spermatheca–spermathecal gland complex. This duct has a thick outer layer of muscle cells. Through muscle contractions, sperm can be pushed forwarding up to the complex of the two organs. A short fertilization duct allows sperm to reach the common oviduct where eggs will be fertilized. The different organization of the genital systems of Sc. halensis and S. optatus might be related to a different reproductive strategy of the two species.
Electron-doped superconductivity induced by oxygen vacancies in as-grown Sr0.6Ca0.4CuO2?? infinite-layer films

Thin films of the infinite-layer compound Sr0.6Ca0. 4CuO2? have been prepared by off-axis rf magnetron sputtering on SrTiO3 (001). For an optimum level of oxygen vacancy superconductivity was observed (Tc onset = 42 K and Tc(? = 0) = 11 K). Structural and transport data suggesting n-type superconductivity are presented and discussed. Infinite-layer thin films of Sr0.6Ca0. 4CuO2? , without trivalent cation doping and showing n-type superconductivity, are reported for the first time.
Fast terminal sliding mode tracking of non-holonomic systems with exponential decay rate

In this study, a recursive singularity-free, fast terminal sliding mode control method, which is able to avoid the possible singularity during the control phase, is applied for a finite-time tracking control of a class of non-holonomic systems. The reaching control law is proposed to guarantee the existence of the sliding mode around the fast terminal sliding surface and zero-tracking errors are achieved in finite time with an exponential decay rate. Simulation results are illustrated on three benchmark examples of chained-form non-holonomic systems: a wheeled mobile robot, an under-actuated rigid body and a front-wheel-drive car. The results demonstrate that the proposed control law achieves favourable tracking performance for non-holonomic systems.
Dairy veterinarians' views on antimicrobial use, resistance and treatment practices

Veterinarians are being asked to provide more oversight of antibiotics used on dairies and promote stewardship of these drugs because of the risk for development of antimicrobial resistance. As organizations work to develop stewardship guidelines, gathering data on veterinarians' views and actual use can better inform those guidelines. The purpose of this project was to survey dairy veterinarians to understand current antimicrobial use practices and views on antimicrobial resistance. A SO-question online survey was developed and a link sent to members of the Academy of Dairy Veterinary Consultants. The final response rate of 41 % (58 of 143) included only practicing veterinarians. Fifty-nine percent did not believe that the current use of antimicrobials on dairy farms contributed to antimicrobial resistance in human pathogens. Most of the respondents (83 % ) felt that there was unnecessary use of antimicrobials on dairies, particularly in pre-weaned calves, primarily due to protocol non-compliance and farmers' or employees' misidentification of healthy animals as sick and treatment of them with antimicrobials. About half the respondents always had written treatment protocols for their clients, and 40% always provided training on those protocols. Blanket dry-cow therapy was recommended by 65% of the practitioners. The results of this survey provide a baseline of western, large dairy herd veterinary antimicrobial use and recommendations. Responses indicated opportunities for dairy practitioners to improve some antimicrobial stewardship practices that could reduce antimicrobial use.
Propagation of Uncertainties Using Improved Surrogate Models

We study the effect of various sources of error on the propagation of uncertain parameters and data through surrogate response surfaces approximating quantities of interest from stochastic differential equations. The main result centers on a novel approach for improving the pointwise accuracy of a surrogate with the use of an adjoint-based a posteriori estimate of its error. A general error analysis on propagated distribution functions for both forward and inverse problems is derived. To provide concrete examples focusing on the use of the improved surrogate, we consider standard polynomial spectral methods to approximate the surrogate. However, neither the definition of the improved surrogate nor the general error analysis for the computed distribution functions requires a specific surrogate formulation. Numerical results comparing pointwise errors in propagated distributions using a surrogate versus its improved counterpart demonstrate global decreases in both actual error and in error bounds for both f.
Epoxy-Modified Bismaleimide Structural Adhesive Film Toughened Synergistically with PEK-C and Core–Shell Polymers for Bonding CFRP

Bismaleimide (BMI) resin-based structural adhesives have excellent heat resistance, with important applications demonstrated in the bonding of high-temperature BMI composites. In this paper, we report an epoxy-modified BMI structural adhesive with excellent properties for bonding BMI-based CFRP. We prepared the BMI adhesive using epoxy-modified BMI as the matrix and PEK-C and core–shell polymers as synergistic tougheners. We found that the epoxy resins improve the process and bonding properties of BMI resin but slightly reduce thermal stability. PEK-C and core–shell polymers synergistically improve the toughness and bonding performances of the modified BMI adhesive system and allow the maintenance of heat resistance. The optimized BMI adhesive exhibits excellent heat resistance, with a high glass transition temperature of 208.6 °C and a high thermal degradation temperature of 425.4 °C. Most importantly, the optimized BMI adhesive exhibits satisfactory intrinsic bonding and thermal stability. It has a high shear strength of 32.0 MPa at room temperature and up to 17.9 MPa at 200 °C. The BMI adhesive-bonded composite joint has a high shear strength of 38.6 and 17.3 MPa at room temperature and 200 °C, respectively, indicating effective bonding and excellent heat resistance.
Adjoint Algorithmic Differentiation and the Derivative of the Cholesky Decomposition

Adjoint Algorithmic Differentiation is an efficient method to calculate the sensitivities of financial instruments to the input parameters. It does require an implementation of the derivative of every elementary step in the pricing algorithm. In particular, for calculating correlation sensitivities in a Monte Carlo simulation it has been proposed to use a step-by-step adjoint derivative of the Cholesky factorization. In this paper we introduce a one-line matrix-level algorithm which uses only matrix inversion and multiplication and can thus be performed by a standard library for linear algebra. Moreover, it allows for a more time-efficient calculation of the standard errors on these sensitivities.

A Robust Indoor Localization Method Based on DAT-SLAM and Template Matching Visual Odometry

Robust positioning is a central issue in robots. Due to the complex indoor environment, visual simultaneous localization and mapping (VSLAM) is susceptible to light and some scenes contain few features. The robot cannot obtain an accurate position. To solve these problems, this work first proposes dynamic adaptive threshold simultaneous localization and mapping (DAT-SLAM), a method for extracting feature points based on a dynamic adaptive threshold. The method is stable for feature extraction under illumination transformation. Subsequently, template matching visual odometry (VO) is introduced and combined with DAT-SLAM to form a joint indoor localization framework. Experiments on the datasets show that DAT-SLAM has a better performance than oriented fast and rotated brief SLAM2 (ORB-SLAM2). The mean positioning accuracy is improved by 11.74%. Experiments in real scenes show that the joint localization framework can achieve continuous localization in scenes with sparse features.
Use of live cultures of Pasteurella haemolytica Pasteurella multocida to immunize cattle against bovine respiratory disease

Bovine respiratory disease is the leading cause of loss to the North American cattle industry. The disease is characterized by a severe fibrinous pneumonia or a suppurative bronchitis and bronchopneumonia. The bacteria most commonly associated with these cases of pneumonia and deaths are Pasteurella haemolytica (PH) and Pasteurella multocida (PM). Attempts to immunize calves with killed bacterins or extracts of these bacteria have been ineffective. Recently several investigators have used live cultures of PH and PM to immunize calves against respiratory disease. The purpose of these investigations was to develop vaccines that effectively immunize calves against pneumonic pasteurellosis. Two vaccines have been developed that contain viable Pasteurella haemolytica (PRECON-PH) or Pasteurella multocida (BOVICON-PM) (A.H. Robins Corporation, Richmond, Va.).
Ultrahigh current densities in Permalloy nanowires on diamond

To study the forces of spin polarized currents on domain walls in the microscopic scale, dc densities in the order of 1012A∕m2 are required. In general, current densities of this magnitude cause a rapid destruction of metallic wires. We present a device that allows us to apply current densities of 1.5×1012A∕m2 for more than an hour without degradation in the wire, using a diamond substrate as heat spreader. Annealing effects are observed and the wire temperature is measured and modeled as function of the current density.
MODAL NEAR-FIELD TO FAR-FIELD TRANSFORMATION FOR FDTD MODELLING OF APERTURE ANTENNAS

This paper describes a new numerical approach for the broad-band analysis of aperture antennas which avoids the use of both ω-domain and k-domain discrete Fourier transform. The FDTD method is adopted for the near field analysis of the antenna and the aperture field is then processed by time-domain modal expansion to obtain broadband gain pattern. The new method is specified for rectangular aperture antennas and is demonstrated by means of some examples.
Analysis of Effect of Ballistic Coefficient in the Formulations and Performance of EKF with Emphasis on Air Drag

In one dimensional vertical motion in the case of tracking a target, many types of filters included Kalman varieties have been used so far. This paper is presenting a new approach of inverse ballistic coefficient included in the target state vector for reducing the convergence time. For analysis, estimation of object’s altitude and velocity is done by simulation based on noisy error environment measurements. The important of beta (ballistic coefficient) for non linear studies on extended Kalman filter has been established with proper evidence. This work can be further extended to consider the effect of hang off errors and air drag.
