Efficient evaluation of integrals of analytic functions by the trapezoidal rule

Definite integrals of analytic functions can often be evaluated efficiently by the trapezoidal rule after a suitable transformation. Here the work of Moran1 and Schwartz2 along this line is extended. First the dependence of the error on the spacing is discussed, and then several types of transformations are described and applied to integrals of technical interest.
LMI RELAXATIONS FOR H∞ CONTROL OF TIME-VARYING POLYTOPIC SYSTEMS BY MEANS OF PARAMETER-DEPENDENT QUADRATICALLY STABILIZING GAINS

Abstract This paper provides necessary and sufficient conditions in terms of LMI relaxations to compute H ∞ parameter-dependent state feedback control gains that ensure closed-loop quadratic stability for linear systems affected by arbitrarily fast time-varying parameters inside a polytope. The proposed conditions, based on an extension of Polya's Theorem and on the systematic construction of homogeneous polynomial solutions for parameter-dependent linear matrix inequalities, are written as a sequence of progressively less and less conservative linear matrix inequality conditions. Necessity is attained as the level of relaxation increases, providing an H ∞ parameter-dependent state feedback gain that quadratically stabilizes the system whenever such a gain exists. An extension to compute decentralized control gains is also presented and numerical results illustrate the efficiency of the proposed conditions.
Active Ras2 in mitochondria promotes regulated cell death in a cAMP/PKA pathway‐dependent manner in budding yeast

Previously, we showed that an aberrant accumulation of activated Ras in mitochondria correlates with an increase in apoptosis. In this article, we show that lack of trehalose‐6P‐synthase, known to trigger apoptosis in Saccharomyces cerevisiae, induces localization of active Ras proteins in mitochondria, confirming the above‐mentioned correlation. Next, by characterizing the ras1Δ and ras2Δ mutants, we show that active Ras2 proteins, which accumulate in the mitochondria following addition of acetic acid (a pro‐apoptotic stimulus), are likely the GTPases involved in regulated cell death, while active Ras1 proteins, constitutively localized in mitochondria, might be involved in a pro‐survival molecular machinery. Finally, by characterizing the gpa2Δ and cyr1Δ mutants, in which the cAMP/PKA pathway is compromised, we show that active mitochondrial Ras proteins promote apoptosis through the cAMP/PKA pathway.
PHOTOELECTRIC PHOTOMETRY: AN APPROACH TO DATA REDUCTION.

The reduction of photoelectric photometry data is examined, and a reduction method which differs significantly from Hardie's (1966) traditional approach is reviewed. Consisting of a multilinear solution for all transformation model parameters, the technique is suitable for modern computing facilities. Programs for broad-band and intermediate-band systems, mathematical solutions, and generalizations are presented, with the most general situation being photometry on different telescopes on different nights. Sample results are given to illustrate the multinight reduction method, and are compared to results of single-night reduction. Practical aspects and advantages are also discussed, and the reduction algorithm is found to be sufficiently powerful and applicable to many general situations, allowing judgments about the data to be made more easily and effectively.
The Emergence of E-Wallet in Sarawak: Factors Influencing the Adoption of Sarawak Pay

This paper discusses the adoption factors of electronic wallet, more specifically Sarawak Pay in Kuching, Sarawak. The Sarawak Government has a very aggressive mandate in terms of digital transformation to boost the e-commerce industry in Sarawak. Propel with the effort of federal and state governments in encouraging a cashless and digital society, Kuching will foresee a rapid rise in the adoption of Sarawak Pay. This paper adopts and expands the Technology Acceptance Model (TAM) in addressing the adoption factors of Sarawak Pay. With a population of three quarter a million, it is vital to understand whether perceived usefulness, perceived ease of use, perceived risk and reward play any significant roles in the adoption of Sarawak Pay. Data were collected from 204 respondents and the results were examined using partial least squares-structured equation modelling (PLS-SEM). Findings indicated that perceived usefulness, perceived ease of use and perceived risk have significant impacts on Sarawak Pay adoption. As a result of the study, the understanding of existing theoretical literature on e-wallets in Malaysia will be enhanced.
RR Lyrae stars and the distant galactic halo : distribution, chemical composition, kinematics and dynamics.

Published observational data on 29 outer-Galactic-halo RR Lyr stars (Saha, 1984, and Saha and Oke, 1984) and from other surveys are analyzed to characterize the mass distribution, chemical composition, kinematics, and dynamics of the outer Galaxy (up to galactocentric radius R = 40 kpc). The results are presented in graphs and tables and discussed. Findings reported include a rapid fall-off of RR Lyr density at R = 25 kpc, Fe/H varying from -1.0 to -2.2 (with two stars at -0.5), no net Fe/H gradient in the far halo, and Galactic mass (from dynamical computations) about 3 x 10 to the 11th solar mass within R = 25 kpc.
Study of Butorphanol, Dezocine and Dexmedetomidine in the Field of Accelerated Recovery of Gynecological Malignancies

: Reducing the adverse stress response of patients in the perioperative period is the most basic principle of accelerated rehabilitation. It is well known that surgery will prompt the body to produce a corresponding stress response, thereby stimulating the body to release various hormones and inflammatory mediators, resulting in enhanced catabolism, which is not conducive to the healing of incisions and wounds. However, a series of measures of accelerated recovery in the perioperative period are precisely to reduce the occurrence of adverse stress reactions in patients. The purpose of this study is to systematically evaluate the efficacy and safety of the concept of fast recovery surgery in the operation of gynecological malignant tumors with the help of Meta analysis method, and to evaluate the efficacy and safety of fast recovery surgery concept in gynecological malignant tumor surgery. The use in tumor patients provides a basis for clinical surgeons to explore the best perioperative treatment plan. The experimental results show that the heart rate wake-up period of patients who use butorphanol 2 mg and dexmedetomidine 0.5 μg is shorter. For dezocine 10 mg and dexmedetomidine 0.5 μg, the heart rate wake-up time of group A was 68.82 minutes and 71.23 minutes, respectively. Butorphanol 2 mg and dexmedetomidine 0.5 μg were used to accelerate the recovery of patients with gynecological malignant tumors. have a certain effect.
Magnus Effect over Finned Projectiles

Computations of steady e ows over yawing and spinning axisymmetric projectiles are largely carried out by numerical algorithms using steady methods. Of particular interest is the prediction of the Magnus force and moment. However this axisymmetric characteristic is lost with e ns addition, and the e ow becomes unsteady whatever the framework is. ONERA and GIAT Industries have developed a new unsteady scheme, based on grid movement, that allows such a turbulent unsteady e ow to be solved. This scheme has been used successfully over a spinning and yawed body-tail cone guration. The Magnus effect is generated on the body by the spin-induced boundary-layer distortion at moderate incidences, whereas asymmetric vortices tend to invert this effect at upper incidences. Fins contribute to an opposite and greater lateral force. The total Magnus force appeared to be linear with respect to angle of attack and spin rate, but the range of linearity of angle of attack is much smaller than for a none nned body.
AN EXAMPLE CONCERNING BOUNDED LINEAR REGULARITY OF SUBSPACES IN HILBERT SPACE

We study bounded linear regularity of finite sets of closed subspaces in a Hilbert space. In particular, we construct for each natural number \(n \ge 3\), a set of \(n\) closed subspaces of \(\ell^{2}\) which has the bounded linear regularity property, while the bounded linear regularity property does not hold for each one of its nonempty, proper non-singleton subsets. We also establish a related theorem regarding the bounded regularity property in metric spaces. 10.1017/S0004972713000749
Psychometric evaluation of the Wound‐QoL questionnaire to assess health‐related quality of life in Chinese people with chronic wounds

Chronic wounds are very common wound types in clinics which have a prolonged and painful healing process. Chronic wounds affect health‐related quality of life (HRQoL) on patients. However, there is no specific instrument to measure the HRQoL in Chinese patients with chronic wounds. Wound‐QoL is a questionnaire targeted the experience of health‐related life to patients with chronic wounds. The study aims to translate and cross‐culturally adapt the Wound‐QoL into Chinese and to evaluate its psychometric properties (validity, reliability, floor, and ceiling effect) in a convenience sample of 203 Chinese outpatients with chronic wounds. Reliability was good, with internal consistency of 0.798–0.960 and test–retest reliability of 0.720–0.838. Criterion‐related validity was assessed by the correlation coefficient between Wound‐QoL and generic European QoL instrument‐ EQ‐5D‐5L, which was found statistically significant (P<.001). No signs of floor or ceiling effect could be detected. Further, confirmatory factor analysis (CFA) was used to verify the reliability and validity of the instrument in this study. In conclusion, the Chinese Wound‐QoL is a valid and reliable tool for measuring HRQoL in populations with chronic wounds.
Local maxima of solutions to some nonsymmetric reaction‐diffusion systems

In this study, we examine the solution profile of some reaction‐diffusion systems. The systems are derived after approximating the Arrhenius term in our system which models the sintering process and consists of two coupled equations in terms of two unknowns. The unknowns describe the temperature of the solid and the concentration of the fuel. We show the evolution over time of local temperature hot spots. The key idea is to use ‘microscopic scaling’ around the temperature hot spot at the initial time along with asymptotic analysis. We also provide some numerical results that support the efficiency of our analysis. Copyright © 2013 John Wiley & Sons, Ltd.
Pavement Recognition Based on Multiple Deep Learning

: In order to meet the development of The Times and enhance the intelligence of new energy vehicles, and solve the problem that the traditional image processing is too demanding for the feature quantity and the recognition effect is poor, a road recognition research based on deep learning is designed. Four deep learning networks (VGGNet, ResNet, GoogLeNet and AlexNet) were used in the study. A large number of images of different road surfaces were collected as experimental data, and the data were trained by the deep learning network. By comparing the results of four kinds of networks, the network which can be used in intelligent vehicles and has better recognition rate is finally analyzed. The research achieved the expected effect and laid the foundation for the subsequent design.
Targeting the CTLA-4/B7 axes in glioblastoma: preclinical evidence and clinical interventions

ABSTRACT Introduction Glioblastoma Multiforme (GBM) is one of the fatal cancers of the Central Nervous System (CNS). A variety of reasons exist for why previous immunotherapy strategies, especially Immune Checkpoint Blockers (ICBs), did not work in treating GBM patients. The cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) is a key immune checkpoint receptor. Its overexpression in cancer and immune cells causes tumor cell progression. CTLA-4 suppresses anti-tumor responses inside the GBM tumor-immune microenvironment. Areas covered It has been attempted to explain the immunobiology of CTLA-4 as well as its interaction with different immune cells and cancer cells that lead to GBM progression. Additionally, CTLA-4 targeting studies have been reviewed and CTLA-4 combination therapy, as a promising therapeutic target and strategy for GBM immunotherapy, is recommended. Expert opinion CTLA-4 could be a possible supplement for future cancer immunotherapies of GBM. However, many challenges remain such as the high toxicity of CTLA-4 blockers, and the unresponsiveness of most patients to immunotherapy. For the future clinical success of CTLA-4 blocker therapy, combination approaches with other targeted treatments would be a potentially effective strategy. Going forward, predictive biomarkers can be used to reduce trial timelines and increase the chance of success.
Brayton-Moser Equations and New Passivity Properties for Nonlinear Electro-Mechanical Systems

This paper presents an alternative framework for a practically relevant class of nonlinear electro-mechanical systems. The formalism is based on a generalization of Brayton and Moser’s mixed-potential function. Instead of focusing on the usual energy-balance, the models are constructed using the power flowing through the system. The main objective is to put forth the mixed-potential function as a new building block for modeling, analysis and controller design purposes for electro-mechanical systems.
Highly Stretchable and Biocompatible Wrinkled Nanoclay‐Composite Hydrogel With Enhanced Sensing Capability for Precise Detection of Myocardial Infarction

It is challenging to balance high biocompability with good mechanical–electrical sensing performance, especially when triggering inflammatory stress response after in vivo implantation. Herein, a bioinspired wrinkle‐reinforced adaptive nanoclay‐interlocked soft strain‐sensor based on a highly stretchable and elastic ionic‐conductive hydrogel is reported. This novel nanoclay‐composite hydrogel exhibits excellent tensile properties and high sensing capacity with steady and reliable sensing performance due to the structural–mechanical–electrical integrity of the nanoclay crosslinked and nano‐reinforced interpenetrating network. The incorporation of amphiphilic ions provides the hydrogel with significant protein resistance, reducing its non‐specific adsorption to proteins upon implantation, improving its biosafety as an implanted device, and maintaining the authenticity of the sensing results. Based on the revealed sensing enhanced mechanism based on hierarchical ordered structures as a proof‐of‐concept application, this hydrogel sensor is demonstrated to be able to accurately localize the region where myocardial infarction occurs and may become a novel strategy for real‐time monitoring of pathological changes in heart disease.
Approximate Solution for the Heat-Transfer-Controlled Growth of a Steadily Translating Vapor Bubble

The existing analytical solution for the problem of the heat-transfer-controlled growth of a spherical vapor bubble moving with a constant velocity under the assumptions of a thin thermal boundary layer and potential flow results in a complicated integral equation for the bubble radius and is too unwieldy to be used in multiphase flow models. The goal of this work is to suggest for this problem an approximate solution that gives correct asymptotic behavior and yields a simpler expression for the bubble growth rate. Comparison with the exact solution showed that this way a good approximation can be obtained.
Observations on the Bessel-Hagen Conservation Laws for Electromagnetic Fields

A derivation of the conservation laws for electromagnetic fields in vacuum which result from the invariance of Maxwell's equations under the conformal group is given. The arguments presented are easier to follow than those given by Bessel-Hagen in 1921, when the original investigation of these conservation laws was made. It is shown in this paper that four of the fifteen conservation laws can be derived from the remaining eleven. Only one of these eleven remains without physical interpretation. This particular conservation law is of some interest today in high-energy physics.
Observations of Mercury's Plasma Sheet Horn: Characterization and Contribution to Proton Precipitation

The Mercury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) spacecraft was the first spacecraft to orbit the planet Mercury. Previous analysis of MESSENGER data has established that of all the planets in the solar system, Mercury's magnetosphere is the most like Earth's, dominated by the Dungey cycle in its dynamic response of the magnetosphere to solar wind forcing. In this work, we identify and describe for the first time Mercury's northern plasma sheet horn—a Dungey cycle feature key to plasma precipitation. We find three possible geometries for potential horn observation by MESSENGER and describe a case study of each. Two additional case studies are presented with geometries particularly favorable to estimating plasma precipitation within the horns. Estimates of proton precipitation flux are performed, which show precipitation levels on the order of 107 per cm2 per second, on the same order of magnitude as the estimated proton precipitation flux in the dayside cusp despite the higher average energy of the protons in the horn. Potential paths for future study of the horns are discussed.
The reduction of blast noise with aqueous foam

Experiments were performed to investigate the potential of water‐based foams to reduce the farfield noise levels produced by demolitions activity. Measurements of the noise reductions in flat‐weighted sound exposure level (FSEL), C‐weighted sound exposure level (CSEL), and peak level were made for a variety of charge masses, foam depths, and foam densities (250:1 and 30:1 expansion ratio foams). Scaling laws were developed to relate the foam depth, foam density, and charge mass to noise reductions. These laws provide consistent results for reductions in the peak level, FSEL and CSEL up to a dimensionless foam depth of 2.5. A two part model for the mechanisms of sound level reductions by foam is suggested.
Neodymium‐doped fluorochlorozirconate glasses as an upconversion model system for high efficiency solar cells

Thermal processing of as‐made fluorozirconate glasses which were additionally doped with neodymium and chlorine ions leads to enhanced upconversion fluorescence intensities. The samples were annealed between 240 °C and 290 °C and the optimum value of upconversion intensity was found for the 270 °C sample. The development of glasses doped with Er, whose luminescence characteristics make it a better choice for application as an upconversion layer on silicon solar cells, is in progress. In addition, we present external quantum efficiency measurements of a silicon solar cell with a NaYF4:Er3+ upconverter. We also show a theoretical analysis where erbium transitions can be enhanced selectively to increase upconversion efficiency. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Modelling Expansion and Densification in Peri-urban Areas: The Case of Goba Ward, Dar es Salaam, Tanzania

Modelling expansion and densification of peri-urban areas may potentially help local authorities and planners to develop intervention strategies for addressing urban planning challenges. This paper employs satellite images information extracted between 2005 and 2020 to predict future expansion and densification trends in Goba ward (Dar es Salaam). 231 grids were established to allow the extraction of data. Each grid was examined from 2005 to 2020 for four periods of five-year intervals. Multiple regression modelling was applied to develop two models (expansion and densification) targeting built-up area and the number of buildings. The results suggest that an increase in the number of buildings will lead to the expansion of a built-up area. High building density in Goba ward has been observed in some areas where economic activities take place (around main centres and main roads). Predictions for expansion and densification show that areas in main centres like Kinzudi, Tegeta A and Goba; and areas around main roads will experience more expansion and densification by 2035. These results inform town planers, decision- and policy-makers to understand the past, current and future situations of expansion and densification; and take proper decisions for enhancing sustainable urban development.
Novel TMA telescope based on ultra precise metal mirrors

Modern telescopes for space applications use complex optical elements like aspheres or freeforms. For the multispectral pushbroom scanner for spaceborne Earth remote sensing the Jena-Optonik GmbH has developed a Jena-Spaceborne- Scanner JSS product line. The optic of JSS-56 imager is realised by a Three-Mirror-Anastigmat (TMA) telescope designed in aluminium [1]. For brilliant pictures, mirrors with high shape accuracy and very smooth surfaces are required. The combination of precise diamond turning and post polishing techniques enables the classical infrared application for the visible and ultra-violet range. A wide variety of complex mirror shapes are feasible. A special new solution for lightweight design was applied. Ultra precise metal mirrors with aspherical surface are developed at the Fraunhofer IOF from design to system integration. This paper summarizes technologies and results for design, fabrication and surface finish of ultra lightweight aspherical metal mirrors for novel TMA telescopes.
