Design optimization of highly accurate elliptical mirrors for hard-x-ray microfocusing probes at SPring-8

This paper presents the design and implementation of focusing optical systems using total reflection mirrors that are customized into three hard x-ray beamlines for four experimental groups at SPring-8. First, for the BL46XU Engineering Science Research III beamline, we designed a vertical focusing mirror and a manipulator to create a high-intensity 20- μm focusing beam, that improves the sensitivity for hard x-ray photoemission spectroscopy. Second, for the BL39XU Magnetic Materials beamline, we designed two pairs of Kirkpatrick-Baez (KB) mirrors and corresponding manipulators for sub-micron focusing and 15 × 15 μm2 high-intensity focusing; these were designed in order to use X-ray magnetic circular dichroism (XMCD) spectroscopy for two-dimensional high-resolution mapping of magnetism and XMCD experiments under high pressures (~10 GPa). Third, for the BL32XU RIKEN Targeted Proteins beamline, we designed KB mirrors for focusing at 1 × 1 μm2; these were designed for carrying out the structural analysis of microcrystal proteins in cooperation with RIKEN SPring-8 Center. These elliptical mirrors and manipulators are currently in the process of being manufactured, and their installation on the beamlines is underway. In this paper, we describe the design considerations, optimized design of the optical system, and installation progress on the beamlines.
Holding Back to Move Forward: The Effects of Retention in the Third Grade on Student Outcomes

We evaluate the effects of grade retention on students’ academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the effects persist into middle school. We find no evidence of grade retention effects on student attendance or disciplinary incidents, again into middle school. Our findings combine to show that Indiana’s third grade retention policy improves achievement for retained students without adverse impacts along (measured) non-academic dimensions.
Measurement of nonuniform bowing in GaN/sapphire epi-wafers and subsequent stress analysis by using a theoretical model

We present our approach to measure the profile of nonuniformly bent GaN epi-wafers grown on sapphire substrates. By using a laser displacement sensor, the position of the epi-wafer is accurately measured and mapped. From the measured profile data, analysis of stress distributions over the nonuniformly bent wafer is performed by using a theoretical model. We show the result of theoretical analysis of how the stress tensors distribute over a wafer. The estimated stress tensors are related with optical properties such as photoluminescence of the wafer.
e-Pupil: IoT-Based Augmentative and Alternative Communication Device Exploiting the Pupillary Near-Reflex

So far, very little attention has been paid to the role of the autonomic nervous system in augmentative alternative communication solutions. In this regard, the pupil near reflex, one component of the triadic accommodative response to a visual plane shift in-depth, may play a key role. Such reflex does not necessitate any requirement of skeletal muscles, and thus may be preserved in diseases affecting somatic motoneurons, such as the amyotrophic lateral sclerosis. On this basis, the pupillary accommodative response, i.e. the pupil constriction in response to a far-to-near visual shift in depth, can constitute an effective communication tool, bypassing the well-known limitations of canonical eye-trackers, which require recruitment of skeletal muscles. This paper introduces e-Pupil: a low-cost, stand-alone, portable and smart device exploiting the pupillary accommodative response as a communication tool. The Internet of Things plays a crucial role in our device, guaranteeing portability, accessibility and usability, as well as several remote functionalities. We propose two different routes to communicate with the external world, both built upon the identification of the pupil constriction event in response to a voluntary far-to-near visual shift. The experimental validation proves the reliability of the system as well as its intrinsic simplicity of use.
Segmenting Lung Fields in CT Image Using Legendre Moments and Active Contour

Conventional methods that perform lung segment -ation in CT slices rely on a large contrast in hounsfield units between the lung and surrounding tissues. However, the lung fields are affected by high density pathologies, and they are discontinuities in the pixel intensities, the traditional segment- ation methods can’t get the good results. Here, we present a new segmentation method of the active contour, which is constraining with respect to a set of fixed reference shapes of lung fields. This approach is based on the shapes descriptors by the legendre moments computed from the shape regions, and it can be used in some complex lung field segmentation, especially suitable for the segmentation of lung field with the juxta-pleural pulmonary nodules. Experiments illustrate that the proposed method is able to segment the lung fields in the CT images successfully.
Genetic variation at the TVB locus in Turkish and Iranian native chicken breeds

Avian leukosis viruses (ALVs) are retroviruses that can induce tumors, as well as reduce growth rate and productivity in chicken. The tumor virus B (TVB) locus encodes the cellular receptor that mediates an infection through ALVB, ALVD, and ALVE subgroups of ALV. Two single nucleotide polymorphisms (SNPs) at nucleotide positions 172 and 184 of the autosomal TVB locus account for the three alleles, TVB*S1, TVB*S3, and TVB*R. The receptor encoded by TVB*R allele prevents viral entry into the cell of ALVB, ALVD, or ALVE subgroups. In this study, both SNPs at the TVB locus of 2 Turkish and 7 Iranian native chicken breeds were investigated by using a PCR-RFLP technique to determine genotypes and gene frequencies at TVB locus. The frequency of TVB*S1, and TVB*S3 alleles changed from 0.857 to 1.000, and from 0.022 to 0.143, respectively, in all studied breeds. The TVB*R allele for resistance to ALV-related viruses was not determined. As a result, it can be concluded that Turkish and Iranian native chickens are strongly susceptible to the infection of ALV-related viruses.
Alternative Geometries for 3D Bioprinting of Calcium Phosphate Cement as Bone Substitute

In the literature, many studies have described the 3D printing of ceramic-based scaffolds (e.g., printing with calcium phosphate cement) in the form of linear structures with layer rotations of 90°, although no right angles can be found in the human body. Therefore, this work focuses on the adaptation of biological shapes, including a layer rotation of only 1°. Sample shapes were printed with calcium phosphate cement using a 3D Bioplotter from EnvisionTec. Both straight and wavy spokes were printed in a round structure with 12 layers. Depending on the strand diameter (200 and 250 µm needle inner diameter) and strand arrangement, maximum failure loads of 444.86 ± 169.39 N for samples without subsequent setting in PBS up to 1280.88 ± 538.66 N after setting in PBS could be achieved.
A novel double keys adapted elliptic curve cryptography and log normalized Gaussian sigmoid adaptive neuro‐fuzzy interference system based secure resource allocation system in decentralized cloud storage

Cloud computing has emerged as a promising platform that grants users direct yet shared access to computing resources and services without worrying about the internal complex infrastructure. However, secure data storage and data retrieval is the basic characteristics. Therefore, this paper proposes a novel double keys adapted elliptic curve cryptography (DKECC) and log normalized Gaussian sigmoid adaptive neuro‐fuzzy interference system (LGS‐ANFIS) based secure resource allocation system in decentralized cloud storage. Initially, the input data undergoes data fragmentation. After that, encryption is carried out using DKECC algorithm. Next, hash code generation using Pearson hash function is done. Then, resource availability is estimated via logistic sine chaotic mapping indulged rock hyraxes swarm optimization technique. Afterwards, data is checked for deduplication. Finally, resource allocation through LGS‐ANFIS takes place. The experimental outcomes demonstrated better results compared to baseline techniques. The modelling process showed that the suggested safe resource allocation model achieves the total security level of 96.27% while also having shorter reaction times (3018 ms), greater throughputs (1258), reduced load balancing (0.355874), and reduced latency (4372 ms).

Issues in the design and analysis of therapeutic trials in human immunodeficiency virus infection

The first randomized trial of antiviral therapy in human immunodeficiency virus (HIV) disease included 282 patients with acquired immune deficiency syndrome (AIDS) or AIDS‐related complex and was stopped in 1986 after an average follow‐up of 4 months because of a substantial reduction in mortality in the group who received zidovudine (AZT). The era of anti‐HIV treatment had begun. This paper discusses some of the difficulties which have emerged over the subsequent 10 years as new anti‐HIV drugs have been developed requiring evaluation in clinical trials. The trials in which the British Medical Research Council has played a major role (the Concorde, Alpha and Delta trials) and some of the key trials conducted by the AIDS Clinical Trials Group (ACTG) (the ACTG 019 and ACTG 175 trials) and the Community Programs for Clinical Research on AIDS (CPCRA) (the CPCRA 007 trial) in the US will be used to illustrate some of the issues faced by clinical trialists and governmental regulatory agencies in the evaluation of therapies for a disease which, in spite of advances in therapy, still has a high mortality.

On approximate likelihood inference in a poisson mixed model

A two‐step estimation approach is proposed for the fixed‐effect parameters, random effects and their variance σ2 of a Poisson mixed model. In the first step, it is proposed to construct a small σ2‐based approximate likelihood function of the data and utilize this function to estimate the fixed‐effect parameters and σ2. In the second step, the random effects are estimated by minimizing their posterior mean squared error. Methods of Waclawiw and Liang (1993) based on so‐called Stein‐type estimating functions and of Breslow and Clayton (1993) based on penalized quasilikelihood are compared with the proposed likelihood method. The results of a simulation study on the performance of all three approaches are reported.
General Practice Patients’ Experiences and Perceptions of the WiserAD Structured Web-Based Support Tool for Antidepressant Deprescribing: Protocol for a Mixed Methods Case Study With Realist Evaluation

Background Research suggests that the rapid increase in worldwide antidepressant use is mainly due to a rise in long-term and potentially inappropriate use. It has been suggested that 1 in 3 antidepressant users among general practice patients are no longer experiencing clinical benefits from their medication and should commence deprescribing. However there are many barriers to antidepressant deprescribing for both patients and clinicians, which adds to the complex nature of reducing or ceasing the medication. As such, antidepressant deprescribing does not routinely occur in clinical practice. Evidence-based supports and interventions for safe and successful antidepressant deprescribing are needed to assist patients and their doctors. Interventions should also include an understanding of how an intervention works, why it works, and whom it is for. Objective This study aims to evaluate how the WiserAD approach to antidepressant deprescribing works, whom it is for, and the underlying circumstances by (1) examining the experiences and perceptions of WiserAD among antidepressant users, (2) identifying the underlying mechanisms of the WiserAD approach to antidepressant deprescribing, and (3) describing in what contexts and to what extent the underlying mechanisms of WiserAD are suited for antidepressant users. Methods A mixed methods case study with realist evaluation will be conducted among participants in the WiserAD randomized controlled trial for antidepressant deprescribing. Quantitative data will be obtained from up to 12 participants from the intervention and control arms at baseline and 3-month follow-up. Baseline data will be used to characterize the sample using descriptive statistics. Paired samples t tests will also be performed to compare responses between baseline and 3-month follow-up for participant self-management, skills, confidence and knowledge, beliefs about medicines, current emotional health, and well-being symptoms. Qualitative data from the same participants will be collected via narrative interview at 3-month follow-up. Quantitative and qualitative data will be converged to form a “case,” and analysis will be conducted within each case with comparisons made across multiple cases. Results Recruitment of participants commenced in October 2022 and will be completed by March 2023. Analysis will be completed by June 2023. Conclusions To our knowledge, this will be the first realist evaluation of an antidepressant deprescribing intervention in general practice. Findings from this evaluation may assist in the implementation of the WiserAD approach to antidepressant deprescribing in routine clinical practice.

Chaos control and sensitivity analysis of a double pendulum arm excited by an RLC circuit based nonlinear shaker

In this paper the dynamical interactions of a double pendulum arm and an electromechanical shaker is investigated. The double pendulum is a three degree of freedom system coupled to an RLC circuit based nonlinear shaker through a magnetic field, and the capacitor voltage is a nonlinear function of the instantaneous electric charge. Numerical simulations show the existence of chaotic behavior for some regions in the parameter space and this behaviour is characterized by power spectral density and Lyapunov exponents. The bifurcation diagram is constructed to explore the qualitative behaviour of the system. This kind of electromechanical system is frequently found in robotic systems, and in order to suppress the chaotic motion, the State-Dependent Riccati Equation (SDRE) control and the Nonlinear Saturation control (NSC) techniques are analyzed. The robustness of these two controllers is tested by a sensitivity analysis to parametric uncertainties.
Controlled Deterministic Secure Quantum Communication Protocol Based on Three-Particle GHZ States in X-Basis

A controlled deterministic secure quantum communication (CDSQC) protocol is proposed based on three-particle GHZ state in X-basis. Only X-basis and Z1Z2X3-basis (composed of Z-basis and X-basis) measurement are required, which makes the scheme more convenient than others in practical applications. By distributing a random key between both sides of the communication and performing classical XOR operation, we realize a one-time-pad scheme, therefore our protocol achieves unconditional secure. Because only user with legitimate identity string can decrypt the secret, our protocol can resist man-in-the middle attack. The three-particle GHZ state in X-basis is used as decoy photons to detect eavesdropping. The detection rate reaches 75% per qubit.
Comparison of VLBI radio source catalogs

Aims. I checked the consistency of recent astrometric radio source catalogs obtained by geodetic very long baseline radio interferometry (VLBI) with the second realization of the International Celestial Reference Frame (ICRF2), released in 2009, which is the most accurate astrometric catalog currently available. Methods. The catalogs were compared to the ICRF2 in terms of radio source coordinates, global second-degree deformations, and error distribution. Results. All catalogs were found to be consistent with the ICRF2 within 20 μas. At high observational rates, the formal error is likely limited to the level of ∼10 μas by correlated-noise errors. The comparison of offsets to ICRF2 against formal errors raised noise floors of the differences between 50 μas and 100 μas, and hence no improvement with respect to the ICRF2. Conclusions. The inconsistencies between catalogs result in differences significantly larger than the accuracy expected for the future realizations of the celestial reference frame. These inconsistencies have to be clarified in the near future in view of the next ICRF realization and accurate linking to reference frames at other frequencies.
A study of M31, M87, NGC 253, and M82 in high-energy gamma rays

The data from the Energetic Gamma Ray Experiment Telescope (EGRET) all-sky survey are examined for emission from the nearby galaxies M31, M87, NGC 253, and M82 in the high-energy (E greater than MeV) gamma-ray range. No significant emission is observed from any of these galaxies. The derived upper limits for all four galaxies are consistent with that expected from cosmic-ray interactions. For M87, the combination of the high-energy gamma-ray and radio data point to a lower limit of 7 microG for the magnetic field in the disk and 4 microG for the magnetic field in the halo, consistent with equipartition arguments. A study of NGC 253 and M82 show that EGRET observations do not sufficiently constrain the mean cosmic-ray energy density to provide more details on the cosmic-ray distribution in starburst galaxies.
Zero-Free Parabolic Regions for Sequences of Polynomials

In this paper, we show that certain sequences of polynomials $\{ p_k (z)\} _{k = 0}^n $, generated from three-term recurrence relations, have no zeros in parabolic regions in the complex plane of the form $y^2 \leqq 4\alpha (x + \alpha )$, $x > - \alpha $. As a special case of this, no partial $s_n (z) = {{\sum _{k = 0}^n z^k } / {k! }}$ of $e^z $ has a zero in $ y^2 \leqq 4(x + 1)$, $x > - 1$, for any $n \geqq 1$. Such zero-free parabolic regions are obtained for Pade approximants of certain meromorphic functions, as well as for the partial sums of certain hypergeometric functions.
Size dependent Cu dielectric function for plasmon spectroscopy: Characterization of colloidal suspension generated by fs laser ablation

Copper metal nanoparticles (Nps) have received increasing interest during the last years due to their potential applications in several fields of science and technology. Their optical properties depend on the characteristics of the dielectric function of the metal, their size, and the type of environment. The contribution of free and bound electrons on the dielectric function of copper Nps is analyzed as well as their influence on its plasmonic properties. The contribution of free electrons is corrected for particle size under 10 nm, introducing a term inversely proportional to the particle's radius in the damping constant. For bound electron contribution, interband transitions from the d-band to the conduction band are considered. For particles with sizes below 2 nm, the larger spacing between electronic energy levels must be taken into account by making the electronic density of states in the conduction band size-dependent. Considering these specific modifications, optical parameters and band energy val.
Integration of CARD (Comfort Ask Relax Distract) for COVID-19 community pharmacy vaccination in children: Effect on implementation outcomes

Introduction: Community pharmacists report that providing vaccinations can be challenging, particularly if the vaccine recipient is a child, because of heightened levels of fear. The objective of this study was to determine acceptability and feasibility of the CARD (Comfort Ask Relax Distract) system as a vaccination delivery framework for children receiving COVID-19 vaccinations in a community pharmacy setting. CARD incorporates evidence-based interventions that reduce fear and immunization stress-related responses in vaccine recipients and was demonstrated to be effective and feasible in other vaccination settings providing vaccinations to children and adults. Methods: This mixed-methods study involved 5 independent pharmacies (with 6 vaccinators) offering COVID-19 vaccinations to children between 5 and 11 years of age. Vaccinating staff and implementation leads from the pharmacy organization participated in a small-scale CARD implementation project (before-and-after design). Afterwards, they filled in quantitative surveys and provided qualitative feedback about their perceptions and experiences in focus group discussions. Qualitative data were analyzed deductively, using the Consolidated Framework for Implementation Research (CFIR). Results: The study was conducted between January 16 and March 20, 2022. Across both quantitative and qualitative measures, vaccinating staff reported positive attitudes about CARD and alignment with their professional roles. They reported that CARD reduced children’s fear and improved the vaccination experiences in children and parents and for themselves. Vaccinators reported increased confidence due to CARD. They reported compatibility of CARD interventions within their practice and that it was time neutral. They maintained use of some interventions after the study. They also provided suggestions and shared concerns about fidelity and future feasibility of continuing various components of the program. Conclusion: CARD was demonstrated to be acceptable and feasible by vaccinators performing vaccinations in children in community pharmacies.
Argentinean Myotis (Chiroptera, Vespertilionidae), including the description of a new species from the Yungas

Myotis is the most speciose genus of mammals in the world and recent taxonomic revisions have revealed an impressive diversity of species in South America. Even so, the phenotypic conservatism of some taxa makes taxonomic delimitation difficult. We perform a taxonomic review of Myotis from Argentina based on qualitative and quantitative morphological characters. Our results confirm the occurrence of 12 species (M. albescens, M. chiloensis, M. dinellii, M. izecksohni, M. keaysi, M. lavali, M. levis, M. nigricans, M. oxyotus, M. riparius, M. ruber, and M. cf. simus) and revealed an additional new species for the Yungas Forest. The new species is small to medium (forearm length ~ 35 mm) and can be distinguished from its congeners by a set of characters that includes forearm length, cranial measurements, discrete craniodental characters, and fur color. This review does not exhaust the need for new systematic studies with Argentinean Myotis, considering the possibility of occurrence of new species and the great morphological variation found for some complex taxa.
