Effect of strain on the efficiency of InGaN-based multijunction solar cell

In this paper, the strain-dependent efficiency of multijunction solar cell (MJSC) is reported for the first time. Using multilayered strain model, the strain induced due to the change in lattice constants in different layers of MJSC is calculated. With the combination of strain and deformation potentials the strain-induced change in band gap energy of different subcells is estimated. The results obtained in our study demonstrate that the efficiency of InGaN-based MJSC is increased under the influence of strain compared to that evaluated without taking into account of strain. It is also found that the strain-dependent change in efficiency depends on the number of subcell layers and their thicknesses. The enhancement of efficiency is resulted from the increasing of open circuit voltage of the subcells under the influence of compressive strain.
Study of the X-+/-(5568) state with semileptonic decays of the B-s(0) meson

We present a study of the X±(5568) using semileptonic decays of the Bs0 meson using the full run II integrated luminosity of 10.4 fb-1 in proton-antiproton collisions at a center of mass energy of 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. We report evidence for a narrow structure, X±(5568), in the decay sequence X±(5568)→Bs0π± where Bs0→μ∓Ds±X, Ds±→ϕπ± which is consistent with the previous measurement by the D0 Collaboration in the hadronic decay mode, X±(5568)→Bs0π± where Bs0→J/ψϕ. The mass and width of this state are measured using a combined fit of the hadronic and semileptonic data, yielding m=5566.9-3.1+3.2(stat)-1.2+0.6(syst) MeV/c2, Γ=18.6-6.1+7.9(stat)-3.8+3.5(syst) MeV/c2 with a significance of 6. 7σ.
Application of the SMES for the Large Scale Accelerator Magnet Power Supply

Power supply for the large-scale accelerator magnets draws a large amount of power from the utility network. For an example, the new proton accelerator complex for high intensity beam (Japan Particle Accelerator Research Complex, J-PARC) is under construction at the Tokai campus of Japan Atomic Energy Agency (JAEA) as a joint project between KEK and JAEA. The J-PARC 50 GeV proton synchrotron (50 GeV-PS) magnets power supplies are constructed with IGBT and IEGT, then the power factor is almost 100%. However, the swing of an active power becomes almost 170 MW, although the average power is about 50 MW. Such large pulse power will give un-allowed disturbances to an ac power line. A SMES system will be required for compensating such as pulse electric power and reducing the disturbances. Case study on circuit configuration of the power supply with SMES and present status of the R&D for the SMES system will be discussed.
Maternity Blues

The studies reported had two purposes: (a) to identify psychological symptoms commonly experienced by mothers in the first few days after childbirth; (b) to use psychometric methods to develop a questionnaire for detecting and measuring these symptoms. A draft 49-item questionnaire was derived by asking 100 newly delivered mothers to volunteer suitable items. The number of items was systematically reduced to 28 while testing the questionnaire on two further samples of newly delivered mothers (n = 100 and n = 50). Cluster analysis of the 28 items yielded seven clusters, the robustness of which was established in a further sample of 87 newly delivered mothers. The validity of the 28-item questionnaire was established. The questionnaire was quick and easy to administer, suitable for repeated administration on consecutive days, and well accepted by mothers.
Self-Interference Pricing-Based MIMO Full-Duplex Precoding

Precoding designs for bidirectional full-duplex (FD) systems have been proposed as potential ways to suppress the effects of self-interference and improve the spectral efficiency of wireless systems. This letter proposes the self-interference pricing based full-duplex precoding (FDP-SIP) algorithm that applies pricing-based precoding at the transmitter to suppress the self-interference prior to the receiver low-noise amplifier (LNA) and analog-to-digital converter (ADC) to avoid overloading while ensuring the receiver linearity. The proposed FDP-SIP algorithm can be implemented without the need of active cancellation at the receiver. Simulation results demonstrate the effectiveness of the proposed FDP-SIP algorithm using both channel models and measured data. In particular, based on the measured data, FDP-SIP algorithm provides the sum-rate nearly 1.8 times that of an optimized half-duplex (HD).
Flaking Out: Student Absences and Snow Days as Disruptions of Instructional Time

Despite the fact that the average American student is absent more than two weeks out of every school year, most research on the effect of instructional time has focused not on attendance but on the length of the school day or year. Student and school fixed effects models using Massachusetts data show a strong relationship between student absences and achievement but no impact of lost instructional time due to school closures. I confirm those findings in instrumental variables models exploiting the fact that moderate snowfall induces student absences while extreme snowfall induces school closures. Prior work ignoring this non-linearity may have mis-attributed the effect of absences to such snow days. Each absence induced by bad weather reduces math achievement by 0.05 standard deviations, suggesting that attendance can account for up to one-fourth of the achievement gap by income. That absences matter but closures do not is consistent with a model of instruction in which coordination of students is the central challenge, as in Lazear (2001). Teachers appear to deal well with coordinated disruptions of instructional time like snow days but deal poorly with disruptions like absences that affect different students at different times.
Basal Cell Carcinoma - Review of Treatment Modalities

Basal cell carcinoma (BCC) is the most common type of skin cancer, thus numerous therapeutic approaches have been developed. Optimal treatment outcome should comprise complete removal of the tumor to the margin of normal tissue with the best possible aesthetic result. Surgical treatment remains the "gold standard" in therapy of BCC, showing excellent cure rates when used within the guidelines. However, it is not always possible to perform surgical excision, since it can be contraindicated in patients with certain comorbidities or in case of extensive size and/or difficult location of the tumor. Therefore, a variety of treatment modalities have been developed including cryotherapy, radiation therapy, photodynamic therapy, topical therapies, laser therapy and recently established systemic therapy. Radiation therapy is commonly performed in patients who are not good candidates for surgery and in cases when extensive or complex surgical procedure is required, often resulting in poor cosmetic outcome. Other treatment options including topical therapies, photodynamic therapy (PDT), cryotherapy, electrodesiccation and curettage are suitable for superficial and/or multiple lesions. Laser treatment, although potentially promising, is still not a widely used treatment modality for BCC, usually used only for small BCCs in low-risk anatomical areas. Finally, systemic therapy, vismodegib, is an orally administered Hedgehog pathway inhibitor, recently approved for treatment of metastatic and locally advanced BCC. The advantages, disadvantages and limitations, as well as cosmetic outcomes of each of these treatment modalities are widely discussed and reviewed in this article. Special emphasis is given to the importance of individual patient approach, taking into consideration all of the possible risks and benefits and patient quality-of-life issues when choosing a treatment modality. Conclusively, this paper aims to present a comprehensive review of current treatment modalities of BCC.
Formation mechanism of superconducting phase and its three-dimensional architecture in pseudo-single-crystal KxFe2−ySe2

Here, we report how the superconducting phase forms in pseudo-single-crystal KxFe2-ySe2. In situ scanning electron microscopy (SEM) observation reveals that, as an order-disorder transition occurs, on cooling, most of the high-temperature iron-vacancy-disordered phase gradually changes into the iron-vacancy-ordered phase whereas a small quantity of the high-temperature phase retains its structure and aggregates to the stripes with more iron concentration but less potassium concentration compared to the iron-vacancy-ordered phase. The stripes that are generally recognized as the superconducting phase are actually formed as a remnant of the high-temperature phase with a compositional change after an “imperfect” order-disorder transition. It should be emphasized that the phase separation in pseudo-single-crystal KxFe2-ySe2 is caused by the iron-vacancy order-disorder transition. The shrinkage of the high-temperature phase and the expansion of the newly created iron-vacancy-ordered phase during the phase separation rule out the mechanism of spinodal decomposition proposed in an early report [Wang et al, Phys. Rev. B 91, 064513 (2015)]. Since the formation of the superconducting phase relies on the occurrence of the iron-vacancy order-disorder transition, it is impossible to synthesize a pure superconducting phase by a conventional solid state reaction or melt growth. By focused ion beam-scanning electron microscopy, we further demonstrate that themore » superconducting phase forms a contiguous three-dimensional architecture composed of parallelepipeds that have a coherent orientation relationship with the iron-vacancy-ordered phase. « less
Temperature dependence of the Raman spectra of single-wall carbon nanotubes

Raman spectra of single-wall carbon nanotubes (SWCNTs) were measured at different temperatures by varying the incident laser power. The elevated temperature of the SWCNTs and multiwall carbon nanotubes (MWCNTs) is confirmed to be due to the presence of impurities, defects, and disorder. The temperature coefficient of the frequency of the C–C stretching mode E2g (GM) and that of the radial breathing mode in the SWCNT were determined to be ∼−0.038 and ∼−0.013 cm−1/K, respectively. It is found that the temperature coefficient of the GM in the SWCNT is larger than that of the MWCNT, highly oriented pyrolytic graphite, and the graphite. This is attributed to the structural characteristic of the SWCNT—a single tubular carbon sheet with smaller diameter.
Polygonal dissections and reversions of series

The Catalan numbers $C_k$ were first studied by Euler, in the context of enumerating triangulations of polygons $P_{k+2}$. Among the many generalizations of this sequence, the Fuss-Catalan numbers $C^{(d)}_k$ count enumerations of dissections of polygons $P_{k(d-1)+2}$ into $(d+1)$-gons. In this paper, we provide a formula enumerating polygonal dissections of $(n+2)$-gons, classified by partitions $\lambda$ of $[n]$. We connect these counts $a_{\lambda}$ to reverse series arising from iterated polynomials. Generalizing this further, we show that the coefficients of the reverse series of polynomials $x=z-\sum_{j=0}^{\infty} b_j z^{j+1}$ enumerate colored polygonal dissections.
In vivo performance of photovoltaic subretinal prosthesis

We have developed a photovoltaic retinal prosthesis, in which camera-captured images are projected onto the retina using pulsed near-IR light. Each pixel in the subretinal implant directly converts pulsed light into local electric current to stimulate the nearby inner retinal neurons. 30 μm-thick implants with pixel sizes of 280, 140 and 70 μm were successfully implanted in the subretinal space of wild type (WT, Long-Evans) and degenerate (Royal College of Surgeons, RCS) rats. Optical Coherence Tomography and fluorescein angiography demonstrated normal retinal thickness and healthy vasculature above the implants upon 6 months follow-up. Stimulation with NIR pulses over the implant elicited robust visual evoked potentials (VEP) at safe irradiance levels. Thresholds increased with decreasing pulse duration and pixel size: with 10 ms pulses it went from 0.5 mW/mm2 on 280 μm pixels to 1.1 mW/mm2 on 140 μm pixels, to 2.1 mW/mm2 on 70 μm pixels. Latency of the implant-evoked VEP was at least 30 ms shorter than in response evoked by the visible light, due to lack of phototransduction. Like with the visible light stimulation in normal sighted animals, amplitude of the implant-induced VEP increased logarithmically with peak irradiance and pulse duration. It decreased with increasing frequency similar to the visible light response in the range of 2 - 10 Hz, but decreased slower than the visible light response at 20 - 40 Hz. Modular design of the photovoltaic arrays allows scalability to a large number of pixels, and combined with the ease of implantation, offers a promising approach to restoration of sight in patients blinded by retinal degenerative diseases.
Classical SMR Application Server SMR Client User ( b ) Parallel SMR Request Application Logic Response RequestResponse UserApplicationApplication Application Server SMR Client User Request Application Logic Response RequestResponse Service Execution Service Execution Parallelizer

State machine replication is a fundamental approach to high availability. Despite the vast literature on the topic, relatively few studies have considered the issues involved in recovering faulty replicas. Recovering a replica requires (a) retrieving and installing an up-to-date replica checkpoint, and (b) restoring and re-executing the log of commands not reflected in the checkpoint. Parallel techniques to state machine replication render recovery particularly challenging since throughput under normal execution (i.e., in the absence of failures) is very high. Consequently, the log of commands that need to be applied until the replica is available is typically large, which delays recovery. In this paper, we present two techniques to optimize recovery in parallel state machine replication. The first technique allows new commands to execute concurrently with the execution of logged commands, before replicas are completely updated. The second technique introduces on-demand state recovery, which allows segments of a checkpoint to be recovered concurrently.
Day‐restricted feeding during pregnancy and lactation programs glucose intolerance and impaired insulin secretion in male rat offspring

The maternal environment during pregnancy and lactation plays a determining role in programming energy metabolism in offspring. Among a myriad of maternal factors, disruptions in the light/dark cycle during pregnancy can program glucose intolerance in offspring. Out‐of‐phase feeding has recently been reported to influence metabolism in adult humans and rodents; however, it is not known whether this environmental factor impacts offspring metabolism when applied during pregnancy and lactation. This study aims to determine whether maternal day‐restricted feeding (DF) influences energy metabolism in offspring.
Introduction : T-cell identity and processing of T-cell progenitors

T lymphocyte development branches off from other lymphoid developmental programs through its requirement for sustained environmental signals through the Notch pathway. In the thymus, Notch signaling induces a succession of T-lineage regulatory factors that collectively create the T-cell identity through distinct steps. This process involves both the staged activation of T-cell identity genes and the staged repression of progenitor-cell-inherited regulatory genes once their roles in self-renewal and population expansion are no longer needed. With the recent characterization of Innate Lymphoid Cells (ILCs) that share transcriptional regulation programs extensively with T cell subsets, T-cell identity can increasingly be seen as defined in modular terms, as the processes selecting and actuating effector function are potentially detachable from the processes generating and selecting clonally unique T-cell receptor structures. The developmental pathways of different classes of T cells and ILCs are distinguished by the numbers of prerequisites of gene rearrangement, selection, and antigen contact before the cells gain access to nearly-common regulatory mechanisms for choosing effector function. Here, the major classes of transcription factors that interact with Notch signals during T-lineage specification are discussed in terms of their roles in these programs, the evidence for their spectra of target genes at different stages, and their cross-regulatory and cooperative actions with each other. Specific topics include Notch modulation of PU.1 and GATA-3, PU.1-Notch competition, the relationship between PU.1 and GATA-3, and the roles of E proteins, Bcl11b, and GATA-3 in guiding acquisition of T-cell identity while avoiding redirection to an ILC fate.
Employability and Job Performance as Links in the Relationship Between Mentoring Receipt and Career Success

This study developed and tested a model that posited employability and job performance as intervening variables in the relationship between receipt of mentoring and career success. Participants were 207 information technology (IT) professionals employed in small and medium-sized enterprises (SMEs) in three European countries. Mentoring receipt was related to both employability and job performance. Employability mediated the relationship of mentoring receipt with objective and subjective career success, as well as its relationship with job performance. The findings indicate that receipt of mentoring is connected to job performance, a link that has hitherto lacked empirical evidence. In addition, they suggest a pivotal role for employability in the relationship of mentoring receipt with job performance and career success. Overall, this study helps unveil the mechanism through which mentoring affects career outcomes. Moreover, it shows that the benefits of mentoring hold outside the context of large corporations.
NAO robot as experimenter: Social cues emitter and neutralizer to bring new results in experimental psychology

The aim of this study is to highlight the impact of social factors on the outcome of well-known experimental situations, as the exchange paradigm of Knetsch, used to measure the endowment effect. This bias in decision making brings individuals to assign a widely greater value to an object when they own it. Using a humanoid robot NAO taking the place of the experimenter and left alone with the participant permits to standardize the social factors and the pragmatics engaged within any participant-experimenter interaction. This feature allowed us to validate the hypothesis that the endowment effect could be produced by pragmatical factors, as politeness rules, inherent to all exchange situations between humans. As a continuation of our previous work presented for IDT 2016, we refined our choice of programming methods, keeping a “Wizard of Oz” method for any time the robot must appear as a social entity and applying a completely preprogrammed behavior when all pragmatic factors related to the presence of an experimenter should be annihilated. These methods were applying to the exchange paradigm. We based here on the same paradigm to measure the endowment effect, the exchange paradigm of Knetsch, and using a NAO robot to conduct the experiments. But in contrast with our previous works, a dissociation of programming technics was introduced: a wizard of Oz and fully pre-programmed behavior. After finding that results obtained do not differ regarding the programming technic chosen from previous experiments, we set up a new pilot study to find out if a specific nonverbal clue emitted by the experimenter and varying within a single fixed method (fully preprogrammed behavior) would be sufficient to produce an endowment effect. For this purpose, the first results obtained by only varying the voice intonations of the robot show that vocal features can constitute an important factor for a human individual to activate the application of social standards towards a robot, bringing him to produce an endowment effect.
Computation of Epipolar Geometry and Trifocal Tensor from Spherical Images

We formulate multiple view geometry for 3D reconstruction using a spherical-camera model as a normalized camera model expressing all central cameras. In the sense of geometry, a central camera is a collection of all rays incident to one point. Generally speaking, most cameras that are widely-used in the field of computer vision and robot vision are designed to fall into the central camera. This is because geometric and algebraic expressions of central cameras are simple compared to ones of non-central cameras. In the history of computer vision, the conventiona l cameras are modeled as pinhole cameras. However, the pinhole-camera model can not express catadioptric, dioptric, and panoramic cameras that also belong to the central cameras. For the use of the spherical-camera model as the normalized camera model of central cameras, we formulate the epipolar geometry and trifocal tensor for the recovery of the camera motions. The formulation based on spherical cameras simplifies the analysis of camera systems involving many different central cameras.
Direct predictive current control of grid connected neutral point clamped inverter for wave power extraction

In consequence of the generic irregularity of wave energy, it is difficult to envisage the performance of a grid connected wave energy converter without simulations. This paper details a study on directly driven, linear, permanent magnet generator based, wave energy extraction scheme provided with grid-connected three phase neutral point-clamped three level inverter. The linear permanent magnet generator is driven by a magnetic translator undergoing reciprocating motion with the floating buoy according to wave movement. It converts the mechanical power to three phase AC power. The converter-inverter system provides a fast, dynamic power balancing from generator to grid. The predictive current controller is used to control the three phase neutral point clamped inverter which calculates the inverter voltage required to force the load current to follow the reference. Simulation model of the system is implemented in Matlab/Simulink. The DC-link voltage is regulated by the converter. Neutral point voltage balancing is achieved through proper selection of inverter switching states. Three phase balanced current injection to the grid at unity power factor has been attained. The results obtained validate effectiveness of the predictive method of current control.
Xanthogranulomatous Prostatitis Presenting as a Prostatic Abscess: Case Report and Review of Literature

Xanthogranulomatous inflammation of the prostate presenting as a prostatic abscess is rare, and we present what we believe to be only the second such case report in the literature. A review of literature related to prostatic abscess as well as xanthogranulomatous inflammation in general is also presented. doi: http://dx.doi. org/10.4021/wjnu89w
Volume Ratio Effect of Dual Oxides With a Different Melting Point on Microstructure of High  $K_{u}$  Co80Pt20 Granular Media

A systematic investigation on magnetic properties and microstructure of Co80Pt20-B2O3 mixed with a high-melting-point oxide of various contents was conducted. It was found that the dual oxides granular media with moderate magnetic properties could be realized by changing the oxide fraction, which could not be realized by only utilizing a single oxide. The reduction of magnetic grain size could be obtained by employing a second oxide with high melting point due to the suppression of lateral magnetic grain growth by high-melting-point oxide at the initial growth region. The control of volume fraction of the high melting point was very essential to obtain small magnetic grains with columnar growth. To obtain a granular medium with small average grain size and narrow distribution, the application of an underlayer with smaller grain size would be needed. A significant reduction of grain size from 5.6 to 4.7 nm in a typical dual oxides granular medium could be observed when 30 vol% B2O3 was partially replaced by 15 vol% Cr2O3.
