ON THE SIX-YEAR PERIOD IN THE RADIAL VELOCITY OF ANTARES A

We examine the century-long historical data and compare it with our new radial-velocity measurements to determine an improved period. We find a period of 2167 ± 5 days (5.93 ± 0.01 years). Both orbital motion and pulsation are considered as possible causes of the velocity variation. Temperature variations we deduce from line-depth ratios support the pulsation hypothesis. A temperature minimum occurs in 2009, 70 days after the radial-velocity minimum. We deduce a radius change of 19% ± 4% from an integration of the radial-velocity curve and predict a visual magnitude variation ∼0.2 from the radius and temperature variation.
Computation of the kernel of linear fractional representations

This paper presents several algorithms for computing the kernel of a linear fractional representation (LFR). This problem is shown to be multi-criteria because, in addition to numerical stability, the complexity of the kernel (/spl Delta/-block size) and its well-posedness radius must also be optimized. Depending on the treated LFR, the proposed algorithms are more or less efficient; their respective advantages are discussed.

Furthermore, the paper briefly presents main challenges that accompany the adoption of big data analytics in companies.
Microstructure and Dielectric Properties of CCTO-P(VDF-TrFE) Nanocomposites

Ceramic/polymer composites made of nanosized CaCu3Ti4O12 (CCTO) powders as filler and P(VDF-TrFE) copolymers as matrix were fabricated by solution casting method followed by a hot-press process. The hot-press process results in a better morphological uniformity in the composites. The morphology of the composites was investigated using scanning electron microscopy, while the dielectric propeorties of the composites at temperatures from room temperature to 125°C were characterized at frequencies from 100 Hz to 1 MHz. It is found that the composites exhibit a relatively high dielectric constant with a small dielectric loss. For example, the flexible composites with 50 vol.% CCTO, the dielectric constant at 1 kHz is 60 with a loss about 0.05.
Synthesizing invariant 3D rigid scattering centers

Automatic Target Recognition (ATR) is difficult in general, but especially with RADAR. However, the problem can be greatly simplified by using the 3-D reconstruction techniques presented at SPIE[Stuff] the previous 2 years. Now, instead of matching seemingly random signals in 1-D or 2-D, one must match scattering centers in 3-D. This method tracks scattering centers through an image collection sequence that would typically be used for SAR image formation. A major difference is that this approach naturally allows object motion (in fact the more the object moves, the better) and the resulting 'image' is a 3-D set of scattering centers scattering centers directly from synthetic data to build a database in anticipation of comparing the relative separability of these reconstructed scattering centers against more traditional approaches for doing ATR.
Dynamic Relaxation Nonlinear Viscoelastic Bending Analysis of Higher-Order Annular Sector Plates

Using higher-order shear deformation theory (HSDT), nonlinear analysis of polymeric plate under uniform transverse pressure is studied considering material nonlinearity for viscoelastic material. The multiaxial stress state of the Schapery single integral equation describes the material behavior by recursive-iterative formulation. The finite difference Dynamic Relaxation (DR) method is utilized to study the annular sector plate, including geometric nonlinearity with in-plane fixed and free clamped and hinged edge constraints. The plate is considered as a laminate of isotropic layers, in which the viscoelastic properties of each layer have their own parameters during the loading. The plate deflection is predicted for different thicknesses and also various pressures at the beginning and end of loading and compared with elastic finite element results. The normal and through-thickness shear stresses are also determined in different time steps.
Using Mean-Shift to Improve Active Shape Model Search

In this paper we introduce a new method for locating shapes. The method is based on active shape model, and combining with mean shift to improve local search in the region around each landmark. Bringing new local descriptor and search strategy to active shape model search, mean shift can improve active shape model in both precision and speed.
A Cost-Effective Work-Based Interprofessional Collaboration Program for Healthcare Professionals

Despite the availability of online interprofessional collaboration (IPC) programs, few cater for low- and middle-income communities and healthcare workers with limited Internet resources. This article describes how an interdisciplinary team developed an IPC blended learning program for healthcare workers in a low- and middle-income maternity setting. The purpose of the article is to discuss and outline how the authors developed an IPC program that is easily accessible and cost-effective to implement in low- and middle-income communities. To scaffold the program content and structure, the authors integrated IPC principles and the ADDIE instructional design model. By discussing the design process and methodology, the article aims to demonstrate how an accessible learning program can be developed using a work-based pedagogy and blended learning approach. In doing so, the authors trust the design process and approach can guide other healthcare professionals and educators in similar contexts, as well as encourage educational professionals to utilize resources optimally.
Treatment-Resistant Bipolar Depression: Therapeutic Trends, Challenges and Future Directions

Introduction Bipolar disorder (BD) is a chronic mental illness impacting 1–2% of the population worldwide and causing high rates of functional impairment. Patients with BD spend most of their time in depressive episodes and up to one-third of patients do not respond to adequate doses of medications. Although no consensus exists for definition of treatment-resistant bipolar depression (TRBD), failure of symptoms improvement despite an adequate trial of two therapeutic agents is a common theme of TRBD. In this paper, we review the evidence base of therapeutic interventions, challenges, and potential future directions for TRBD. Methods We conducted a literature search for randomized controlled trials on PubMed for the treatment of TRBD and ongoing trials for the treatment of TRBD/bipolar depression on clinicaltrials.gov. Results Several therapeutic agents have been investigated for TRBD. Adjunctive pramipexole and modafinil have data supporting short-term efficacy in TRBD, along with limited data for racemic intravenous ketamine. Celecoxib augmentation of escitalopram and treatment with metformin in patients with insulin resistance showed promising results. Right unilateral electroconvulsive therapy displayed statistically significant response rate and improvement, but not remission compared to pharmacotherapy. Trials for transcranial magnetic stimulation (TMS) have failed to show a significant difference from sham treatment in TRBD. Future Trends Pharmacological treatments with novel mechanisms of actions like brexpiprazole and vortioxetine are being investigated following successes in unipolar depression. Modified TMS protocols such as accelerated TMS are under investigation. Innovative approaches like psychedelic-assisted psychotherapy, interleukin-2, fecal microbiota transplantation and multipotent stromal cells are being studied. Conclusion Evidence on current treatment modalities for TRBD is limited with low efficacy. More research is needed for successful treatment of TRBD. Effective therapies and innovative approaches to treatment are being investigated and could show promise.
Ginga Observations of Hercules X-1: Spectrum Dependence on 35 Day Phase

Her X-1 was observed with good coverage and good sensitivity over a wide range of 35 day phase with the Ginga LAC in 1988 and 1989. Although several small sections have been previously studied, the spectra from this full set of observations have not been analyzed previously. Main high, short high, and low state spectra all require a two component continuum (absorbed and unabsorbed). Dips and eclipses were identified and the behavior of spectral parameters outside these events is studied. Excluding dips/eclipses, the iron line energy is ≃6.60 keV (whereas during dips/eclipses, it drops to ≃6.4 keV); the column density of the absorbed component is NH ≃ 1024.0cm-2; and the power-law index is α ≃ 0.95. The iron line intensity is well correlated with the total continuum intensity, indicating that reprocessing is important at all times and that a major source of the iron line is the accretion column during main high. The iron line equivalent width (EW) varies between main high, short high, and low states, with mean values for each state of 0.48 keV, 0.66 keV, and ≃1.37 keV, respectively. The ratio of absorbed continuum to unabsorbed continuum, R, also varies with 35 day phase, and EW is correlated with R. The behaviors of absorbed and unabsorbed continuum normalizations, EW and R are consistent with the accretion-column inner-disk model of Scott, Leahy, & Wilson.
The status of roots in event composition: Laz

In this paper, based on the empirical data from the Pazar dialect of Laz (PL), the status of roots in event composition is revisited. The basic proposal is that the event structure building mechanism in Ramchand (2008) can be incorportated into the cyclic spell-out system of Pantcheva (2011) in the framework known as Nanosyntax (Starke 2009). The association model in Ramchand (2008) that does not recognize root as a syntactic node is shown to undergenerate. In particular, the aspectual system of PL, which appears to provide the lexical match for the event heads/features, creates a theory-internal problem with respect to the root whose potential matching nodes are already lexically occupied. If cyclic phrasal spell-out is adopted and the root is acknowledged as a syntactic node elligible for lexical matching, not only the theory-internal problem is solved but also an interesting case of root allomorphy is accounted for. The proposal appears to be in line with the emprical facts in that all attested patterns of allomorphy are allowed whereas unpredicted lexicalization patterns are outlawed. keyworDs: cyclic spell-out, event structure, Laz, nanosyntax, root. 1. DESCRIPTION OF LAZ FACTS* The Pazar dialect of Laz (henceforth PL) is an endangered South-Caucasian language spoken in Turkey. PL exhibits typologically rare and theoretically interesting morphosyntactic properties. In particular, the case alignment system and the aspectual marking properties of PL reveal a fine-grained cartography of the thematic/event structure domain. In the following two subsections, the case alignment and aspectual marking system of PL will be discussed. It will be shown that the case system encodes the basic argument structure (i.e. external vs. internal split) while the aspectual marking appears to be the morphological manifestation of the fine-grained event structure. * I owe my thanks to my Laz informant İsmail Avci-Bucaklişi and the audience at the WoRSE in Tromsø.

Primary frequency regulation strategy of wind turbine based on adaptive control

Due to the decoupling of the rotor speed and the system frequency, the Double-Fed Induction Generator (DFIG) cannot participate in the primary frequency regulation of the system, which reduces the stability of the wind turbine system with a high proportion. In the traditional integrated control, the fixed coefficient is usually used, which cannot change the parameters in real time according to the change of wind speed and system frequency to participate in the system frequency modulation. Therefore, in order to improve the ability of the wind turbine to respond to the frequency of the system, this paper proposes a wind turbine primary frequency modulation strategy based on adaptive control. By combining the adaptive load reduction control with the adaptive virtual inertia integrated control, the load reduction ratio, the virtual inertia coefficient and the droop coefficient can be adjusted adaptively with the actual wind condition and the system frequency deviation. The simulation results show that the adaptive control strategy can improve the ability of the wind turbine to participate in the primary frequency modulation of the system, so as to improve the safety and reliability of the system.
CSpace high-resolution volumetric 3D display

We are currently in the process of developing a static-volume 3D display, CSpace® display, that has the capability to produce images of much larger size than any other static-volume display currently under development, with up to nearly 800 million voxel resolution. A key component in achieving the size and resolution of the display is the optical system that transfers the pixel data from a standard DMD projection unit to the voxel size required by the display with high contrast and minimal distortion. The current optical system is capable of such performance for only small image sizes, and thus new designs of the optical system must be developed. We report here on the design and testing of a new optical projection system with the intent of achieving performance close to that of a telecentric lens. Theoretical analysis with Zemax allowed selection of appropriate lens size, spacing, and focal length, and identified the need for tilting the assembly to produce the desired beam properties. Experimental analysis using the CSpace® prototype showed that the improved beam parameters allowed for higher resolution and brighter images than those previously achieved, though their remains room for further improvement of the design. Heating of the DMD and its housing components were also addressed to minimize heating effects on the optical system. A combination of a thermo-electric cooler and a small fan produced sufficient cooling to stabilize the temperature of the system to acceptable levels.
Data-Based Resolution Selection in Positive Wavelet Density Estimation

Abstract The problem of automatic resolution selection for positive wavelet density estimators is considered. Asymptotic formulae for the integrated mean square error (IMSE) of positive wavelet density estimators are derived under a very mild condition on the density function f. Using the formula for IMSE, an asymptotically optimal empirical resolution selection rule is given. The consistency of the density estimator with estimated resolution is also proved.
A Review of: “ Controversial Statistical Issues in Clinical Trials , by S.-C. Chow”

This book identifies 26 issues judged by the author to be controversial. It is the goal of the author that the book will provide a vehicle for regulatory agencies, clinical scientists, and biostatisticians to resolve/correct these issues and potentially enhance the level of good clinical and good statistical practice in clinical trials. The book has 27 chapters: an introductory chapter outlining the aim and structure of the book and providing a high-level overview of the 26 controversial issues, and a separate chapter for each of these issues. Professor Chow and co-authors Lan-Yan Yang and Ying Lu published a synopsis of eight of the chapters (Chapters 5–12) in a 2011 issue of the Drug Information Journal (Chow et al., 2011). This publication was reviewed at the November 9, 2011, meeting of the Virtual Journal Club of the Drug Information Association (DIA) Statistics Special Interest Area Community (SIAC). Robert O’Neill of the Food and Drug Administration (FDA) and Jerald Schindler of Merck were formal discussants. I start my review here with the eight chapters summarized in the DIA publication, incorporating key comments from participants at the Virtual Journal Club meeting to supplement my own comments. I then review the remaining 18 chapters and conclude with some comments about some errors in the book (typographical and missing references) and some other potentially controversial issues that might be addressed in subsequent editions of the book. Chapter 5 suggests that designing a trial to have adequate power to detect a clinically meaningful treatment effect based on the prespecified primary variable, generally measuring efficacy may not have adequate power to evaluate the treatment performance based on both efficacy and safety (the controversy). The author proposes testing a composite hypothesis that takes both efficacy and safety into consideration. The alternative hypothesis for each component may be superiority, noninferiority, or equivalence, leading to nine different types of alternative composite hypotheses. Comment from Robert O’Neill: Safety issues may be better addressed in prospective meta-analyses of clinical trials—for example, cardiovascular risk with antidiabetic drugs—than as a composite endpoint in a single clinical trial. Reviewer’s comment: It may be difficult to prospectively specify the safety risk from a therapeutic agent with a novel mechanism of action, and the acceptable safety margin in a life-threatening indication may depend on the level of efficacy observed. Chapter 6 discusses the instability of sample size estimates, particularly if based on a small pilot study. In the Gaussian location setting, the sample size
The interstellar medium near the sun. III - Detailed analysis of the line of sight to lambda Scorpii

Profile fitting of ultraviolet interstellar absorption lines is used to separate five different absorbing regions between Earth and the nearby star lambda Sco. Two diffuse H ii regions are found to be density bounded, with n/sub e/approx.0. 1 and Tapprox.10/sup 4/ K, and to have depletions of the refractory species Fe and Si similar to those found for the H i regions in the same direction. The ionization of these components is consistent with a radiation field typical of a 24,000 K star pervading most of the space along this line of sight. A single (warm) H i region is found, with a size < or approx. =5 pc. Two additional, possibly shock-heated components may be related to the H ii regions or to the H i region. High-resolution observations are described that would allow a more definitive model to be constructed for this line of sight.
Current Advances in 3D Dynamic Cell Culture Systems

The traditional two-dimensional (2D) cell culture methods have a long history of mimicking in vivo cell growth. However, these methods cannot fully represent physiological conditions, which lack two major indexes of the in vivo environment; one is a three-dimensional 3D cell environment, and the other is mechanical stimulation; therefore, they are incapable of replicating the essential cellular communications between cell to cell, cell to the extracellular matrix, and cellular responses to dynamic mechanical stimulation in a physiological condition of body movement and blood flow. To solve these problems and challenges, 3D cell carriers have been gradually developed to provide a 3D matrix-like structure for cell attachment, proliferation, differentiation, and communication in static and dynamic culture conditions. 3D cell carriers in dynamic culture systems could primarily provide different mechanical stimulations which further mimic the real in vivo microenvironment. In this review, the current advances in 3D dynamic cell culture approaches have been introduced, with their advantages and disadvantages being discussed in comparison to traditional 2D cell culture in static conditions.
A 50-nm-gate-length erbium-silicided n-type Schottky barrier metal-oxide-semiconductor field-effect transistor

The theoretical and experimental current–voltage characteristics of 50-nm-gate-length erbium-silicided n-type Schottky barrier metal-oxide-semiconductor field-effect transistors (SB-MOSFETs) are discussed. The manufactured 50-nm-gate-length n-type SB-MOSFET shows large on/off current ratio with low leakage current less than 10−4 μA/μm. The saturation current is 120 μA/μm when drain and gate voltage is 1 and 3 V, respectively. The experimental current–voltage characteristics of 50-nm-gate-length n-type SB-MOSFET are fitted using newly developed theoretical model. From the theoretical analysis, the off- and on-current is mainly attributed to the thermionic and tunneling current, respectively. The decrease of tunneling distance at silicon/silicide Schottky junction with the increase of drain voltage gives the increase of tunneling current. This phenomenon is explained by using drain-induced Schottky barrier thickness thinning effect.
Note on the existence and uniqueness of optimum lifting surfaces with reduced tip vorticity

In linearized optimization theory, lifting surfaces shed tip vorticity of which the strength has in general infinite square root singularities. Here we impose, besides the usual condition on the force action of the lifting surfaces, also a condition on the strength of their shed vorticity by which it remains bounded. Then the existence of a unique optimum under both conditions is proved. Copyright © 2002 John Wiley & Sons, Ltd.
On the Frequency Limits of Binaural Beats

The report describes measurements of the frequency limits of binaural beats and outlines a theory of binaural beats, based on synchronous discharges in the two auditory nerves. Two sinusoids of frequencies f1 (fixed) and f2 (variable) were led separately to the two ears; and the difference Δf = |f1−f2| that marked the disappearance of the fluctuating loudness or roughness that is characteristic of binaural beats was determined. Δf was maximal (approximately 35 c.p.s.) for frequencies in the neighborhood of 400 c.p.s. Binaural beats were heard above 1000 c.p.s. , but careful attention was required and Δf was small. The shape of the curve relating Δf to f1 provides an explanation for the fact that determinations of the upper frequency limit of binaural beats have not been in agreement; the upper frequency limit depends markedly on Δf. The theory, given to account for the fact that Δf is smaller both at low and at high frequencies than it is near 400 c.p.s. , combines elements of the Hill‐Rashevsky theory of t.
On fields with the Property (B)

Let K be a number field and let L/K be an infinite Galois extension with Galois group G. Let us assume that G/Z(G) has finite exponent. We show that L has the Property (B) of Bombieri and Zannier: the absolute and logarithmic Weil height on L^* (outside the set of roots of unity) is bounded from below by an absolute constant. We discuss some feature of Property (B): stability by algebraic extensions, relations with field arithmetic. As a as a side result, we prove that the Galois group over Q of the compositum of all totally real fields is torsion free.
