Seven-Doppler Radar and In Situ Analysis of the 25–26 June 2015 Kansas MCS during PECAN

This case study analyzes a nocturnal mesoscale convective system (MCS) that was observed on 25–26 June 2015 in northeastern Kansas during the Plains Elevated Convection At Night (PECAN) project. Over the course of the observational period, a broken line of elevated nocturnal convective cells initiated around 0230 UTC on the cool side of a stationary front and subsequently merged to form a quasi-linear MCS that later developed strong, surface-based outflow and a trailing stratiform region. This study combines radar observations with mobile and fixed mesonet and sounding data taken during PECAN to analyze the kinematics and thermodynamics of the MCS from 0300 to 0630 UTC. This study is unique in that 38 consecutive multi-Doppler wind analyses are examined over the 3.5 h observation period, facilitating a long-duration analysis of the kinematic evolution of the nocturnal MCS. Radar analyses reveal that the initial convective cells and linear MCS are elevated and sustained by an elevated residual layer formed via weak ascent over the stationary front. During upscale growth, individual convective cells develop storm-scale cold pools due to pockets of descending rear-to-front flow that are measured by mobile mesonets. By 0500 UTC, kinematic analysis and mesonet observations show that the MCS has a surface-based cold pool and that convective line updrafts are ingesting parcels from below the stable layer. In this environment, the elevated system has become surface based since the cold pool lifting is sufficient for surface-based parcels to overcome the CIN associated with the frontal stable layer.
Systematic literature review of fuzzy logic based text summarization

Information Overloadrq is not a new term but with the massive development in technology which enables anytime, anywhere, easy and unlimited access; participation & publishing of information has consequently escalated its impact. Assisting userslq informational searches with reduced reading surfing time by extracting and evaluating accurate, authentic & relevant information are the primary concerns in the present milieu. Automatic text summarization is the process of condensing an original document into shorter form to create smaller, compact version from the abundant information that is available, preserving the content & meaning such that it meets the needs of the user. Though many summarization techniques have been proposed but there are no lq silver bulletsrq to achieve the superlative results as of human generated summaries. Thus, the domain of text summarization is an active and dynamic field of study, practice & research with the continuous need to expound novel techniques for achieving comparable & effectual results. Fuzzy logic has appeared as a powerful theoretical framework for studying human reasoning and its application has been explored within the domain of text summarization in the past few years. This paper is a systematic literature review to gather, analyze, and report the trends, gaps and prospects of using fuzzy logic for automatic text summarization on the basis of the findings in original studies.
Global method for learning an integrated temperature prediction model in a slab reheating furnace

Temperature prediction in a slab heating furnace is an important problem for steel production processes. However, the problem is complicated owing to process complexity and industrial noise. These factors make it difficult to obtain precise prediction results by a mechanism model in practical production. In this article, an integrated modelling approach is proposed through combining mechanism and data-driven models. This method constructs a generalized-kernel support vector regression (SVR) on new search space to improve the predictive performance of a mechanism model, in which the kernel matrix is a combination of multiple single kernels. The learning problem can be solved globally by a semi-definite programming (SDP) problem. Numerical experiments using actual data from an iron and steel enterprise in China are performed to illustrate the effectiveness of the proposed integrated method.
Glide-Symmetric Holey Leaky-Wave Antenna With Low Dispersion for 60 GHz Point-to-Point Communications

In this article, two novel efficient leaky-wave antennas (LWAs) with stable radiation patterns operating in the 60 GHz band are proposed. The LWAs are implemented in groove-gap waveguide (GGW) technology. To mitigate the beam squint due to the dispersive nature of LWAs, complementary-dispersive prisms are coupled to the LWA radiation aperture. The antennas are implemented in fully metallic purely holey periodic structures, resulting in a more cost-effective and robust manufacturing process compared to previously reported pin-based structures. Two prisms are proposed, one with mirror symmetry and one with glide symmetry. When the prism possesses a glide symmetry, much fewer holes are required while maintaining a similar performance, which even further decreases the fabrication costs. The complex propagation constant is optimized for low sidelobe levels (SLLs) with tailored hole diameters and waveguide dimensions, thus for the first time demonstrating the capability of using glide-symmetric holes to control the leakage rate. Two prototypes with mirror- and glide-symmetric prisms are theoretically synthesized and validated by the simulated and experimental results. A frequency bandwidth of 11% is achieved for both prototypes with the beam squint within ±0.9° (mirror) and ±1.7° (glide), SLLs below −15 dB (mirror) and −13 dB (glide), total efficiency almost 90%, and realized gain of 17 ± 0.5 dB at a fixed observing angle. The developed antennas are intended for mm-wave point-to-point communications.
Non-fragile L 2 − L ∞ synchronization for chaotic time-delay neural networks with semi-Markovian jump parameters

The issue of the non-fragile L 2 − L ∞ synchronization for chaotic time-delay neural networks subject to semi-Markovian jump parameters is addressed in this paper. Unlike the Markovian jump process, the sojourn time of the semi-Markovian jump process allows to be non-exponential distributed and the transition rate allows to be time-varying. By utilizing the discretized Lyapunov–Krasovskii functional method and introducing two free-weighting matrices, a sufficient condition is proposed to ensure the synchronization error system to be stochastically stable with an L 2 − L ∞ performance index. Then, by means of a matrix congruence transformation and some inequality techniques, an approach to the non-fragile L 2 − L ∞ controller design is developed. Finally, two illustrative examples are employed to show the usefulness of the proposed results.
Theoretical Prediction Model of Tip Leakage Vortex in a Mixed Flow Pump With Tip Clearance

Tip clearance results in the leakage flow from blade pressure side to suction side, which will further cause the tip leakage vortex (TLV). Moreover, the flow pattern in an impeller is seriously deteriorated due to the TLV and its interaction with the main stream. In this work, the TLV in a mixed flow pump is investigated by numerical simulation validated by experiment measurement. The primary tip leakage vortex (PTLV) trajectory is specially studied with consideration of the tip clearance size δ, the impeller blade number Zi, and the impeller rotational speed n. The results show that δ slightly shifts the separation point (SP) of the PTLV but rarely affects the separation angle α. The increase in Zi and the decrease in n both lead to the shift of the SP toward the blade trailing edge and the decrease in α. Furthermore, a theoretical prediction model is proposed to predict the PTLV trajectory, by which the axial position and radial position of PTLV trajectory versus the rotation angle can be predicted. The proposed model is verified to be accurate to predict the PTLV trajectory, especially for the PTLV trajectory in the main flow passage. The dynamic evolution of TLV under different tip clearance sizes can all be classified into the same three stages: splitting stage, developing stage, and merging stage. Meanwhile, the dynamic evolution frequency fe is the same as the impeller rotational frequency fi.
They Categorized Lower Order Thinking Skills but They Answer Incorrectly: How is the Opposite?

This study began with the discovery of writings in several journals about the difficulties of students in learning physics, as well as the importance of the role of using representation in the teaching and learning process to help students to solve problems. The purpose of this research is to identify the consistency of student responses of the test based on representation diagrams in the category of Low Order Category Thinking Skills (LOTS) and High Order Thinking Skills (HOTS). The test is designed only requires answers in the form of drawings or diagrams of the physics topic about dynamics. Participants in this research were 22 teacher-candidate students who had passed the course of Evaluation of Physics Learning. The results of the study found that those they categorized LOTS are 63.6% answered incorrectly and 19% did not answer, and those they categorized HOTS are 73.6% answered incorrectly and 26.4% did not answer. The implication of the results of this research is that for basic sciences such as physics requires mastery for all levels of thinking ability, not only for mastering mathematics as a tool but also for a good understanding of the use of representation diagrams.
On the spectrum of the Schrödinger operator on 𝕋d: a normal form approach

Abstract In this paper, we study the spectrum of the operator (0.1) on with Γ a maximal dimension lattice in and a pseudodifferential operator of order strictly smaller than M. We prove that most of its eigenvalues admit the asymptotic expansion (0.2) where Z is a function (symbol) and (the dual lattice of Γ).
A Wideband Resonant Cavity Antenna With Compact Partially Reflective Surface

A novel wideband resonant cavity antenna (RCA) with compact partially reflective surface (PRS) is presented, which is composed of a superstrate and a feed antenna. The superstrate is a dielectric slab with double-deck periodic array structure, where the superstratum is composed of square loop cells and substratum is composed of square loop aperture cells. This shows positive reflection coefficient phase, which in turn helps in obtaining wider RCA bandwidth. Contrary to the patch cell periodic array, a periodic array composed of square loop cells provides further compact structure. The feed system is a wideband aperture-coupled patch antenna, which is composed of square patch, ground plane with I-shaped slot, and fork-shaped feed network. This dual-arm feed network helps in obtaining the maximum gain at the center frequency. The superstrate with positive reflection coefficient phase provides the minimum gain at the resonant frequency. This in turn helps RCA in obtaining invariant gain in the operation band. Experimental verification was performed and the results show that this RCA offers fractional bandwidth of around 23.6% at $X$ -band (8.88–11.25 GHz, S11 ≤ −10 dB) and gain (13.36–13.92 dBi) is almost invariant over the bandwidth. The measured patterns are symmetric with low cross-polarization levels.
Rate of Pregnancy-Related Relapse in Multiple Sclerosis

Background and Methods Multiple sclerosis often occurs in young women, and the effect of pregnancy on the disease is poorly understood. We studied 254 women with multiple sclerosis during 269 pregnancies in 12 European countries. The women were followed during their pregnancies and for up to 12 months after delivery to determine the rate of relapse per trimester and the score on the Kurtzke Expanded Disability Status Scale (range, 0 to 10, with higher scores indicating more severe disability). The relapse rate in each trimester was compared with the rate during the year before the pregnancy. The effects of epidural analgesia and breast-feeding on the frequency of relapse during the first three months post partum and the disability score at 12 months post partum were also determined. Results The mean (±SD) rate of relapse was 0.7±0.9 per woman per year in the year before pregnancy; it was 0.5±1.3 during the first trimester (P=0.03 for the comparison with the rate before pregnancy), 0.6±1.6 during the secon.
Hypercalcemia and Malignancy

Hypercalcaemia is a common accompaniment of malignancy, and although it is most frequently associated with metastatic disease it may also accompany localised tumours. To the latter situation has been applied the name "pseudo-hyperparathyroidism". The term "ectopic PTH syndrome" is best avoided as it implies that the tumour secretes parathyroid hormone (PTH) which has been shown to be untrue in many cases. The possible causes of hypercalcaemia in malignancy are as follows: metastatic bone disease; production of PTH by the • tumour; production of a parathyrotrophic agent by the tumour; concomitant primary hyperparathyroidism; production of a hypercalcaemic agent other than PTH by the tumour; immobilisation; other causes unrelated to the malignant state, e.g., vitamin D therapy, sarcoidosis etc. stases. In studying cases of carcinoma of the bronchus, Bender and Hansen (1974) noticed that when skeletal secondaries were present, 27 % of squamous cell tumours had associated hypercalcaemia while only 2% of small cell tumours or adenocarcinomas produced this biochemical change. A similar difference in incidence of hypercalcaemia was found when no skeletal metastases were detected, further emphasising that the presence of metastases was a less important factor than the tumour type. Such evidence suggests that humoral agents are involved even in those cases with metastases in bone. The nature of these agents, and whether they are produced by the primary or secondary lesions or both, remains to be clarified.
Direct observation of terahertz emission from ultrafast spin dynamics in thick ferromagnetic films

We have experimentally investigated the field- and fluence-dependent terahertz (THz) emission behaviors by a femtosecond optical pump in Co ferromagnetic films, together with the time-resolved magneto-optical Kerr effect measurement. The thickness of Co and Ta capping layers has been systematically varied. For thick films, THz emission behavior is found to be directly matched with the photoinduced ultrafast demagnetization and remagnetization dynamics. The angle-dependent THz emission measurement also confirms a direct relation between the THz emission and the photoinduced demagnetization/remagnetization dynamics in the case of thick films, while THz emission from the inverse spin Hall effect also plays a role in the case of thin Co films.We have experimentally investigated the field- and fluence-dependent terahertz (THz) emission behaviors by a femtosecond optical pump in Co ferromagnetic films, together with the time-resolved magneto-optical Kerr effect measurement.

Treatment of Advanced Non-small Cell Lung Cancer by Chemotherapy Combined with Autologous Cytokine-induced Killer Cells

Objective The clinical efficacy of chemotherapy was evaluated combined with cytokine-induced killer(CIK) cells biotherapy to advanced non-small cell lung cancer(NSCLC). Methods Fifty-nine advanced NSCLC patients were fractionated group A(CIK cells biotherapy plus chemotherapy) and group B(chemotherapy alone). The host cellular immune function, quality of life(QOL), response rate(RR), time to progression (TTP) and median survival time (MST) were compared between the two groups. CIK cells were induced from autologous peripheral mononuclear cells. Results Amounts and cytotoxic activity of CIK cells reached the peak between days 14 to 21. The host immune function was increased and QOL was improved in patients in group B campared with group A, the disease control rate (DCR) was higher, the MST was longer, the TTP and overall survival(OS) were significantly prolonged. The RR has no significant difference between the 2 groups. Conclusion It is safe to patients by autologous CIK cells transfusion. Chemotherapy combined with CIK cells has benefits for the patients suffering from advanced NSCLC, and there is advantage to chemotherapy alone in terms of QOL, DCR, TTP and survival.
Gaia 8: Discovery of a star cluster containing β Lyrae

Aims. The aim here is to try and clarify whether there are stars in the neighbourhood of β Lyrae which are physically connected to the famous prototype eclipsing binary. Methods. We scrutinised the astrometric and photometric data (from HIPPARCOS and Gaia DR2) of stars in a limited sky field around β Lyrae. Results. A star cluster of about 100 members was discovered, nicely centred on β Lyrae in five dimensions. There are clear indications that the newly discovered cluster belongs to a larger old (extinct) star formation complex, including two known star clusters and an extended, strewn field of stars at practically the same distance and space velocity. Conclusions. This discovery opens up the possibility of determining a precise distance and precise age for β Lyrae using the combined properties of the cluster members. This in turn may form an important basis for an improved astrophysical interpretation of the model binary β Lyrae and its kin. The larger old star formation complex is of scientific interest in its own right.
Meta-Neighborhoods

Traditional methods for training neural networks use training data just once, as it is discarded after training. Instead, in this work we also leverage the training data during testing to adjust the network and gain more expressivity. Our approach, named Meta-Neighborhoods, is developed under a multi-task learning framework and is a generalization of k-nearest neighbors methods. It can flexibly adapt network parameters w.r. t. different query data using their respective local neighborhood information. Local information is learned and stored in a dictionary of learnable neighbors rather than directly retrieved from the training set for greater flexibility and performance. The network parameters and the dictionary are optimized end-to-end via meta-learning. Extensive experiments demonstrate that Meta-Neighborhoods consistently improved classification and regression performance across various network architectures and datasets. We also observed superior improvements than other state-of-the-art meta-learning methods designed to improve supervised learning.
Caregiver Education as a Prevention Strategy for Communication Disorders in South Africa

Many early interventionists in clinical practice still do not appear to be wholeheartedly committed to participating in the prevention of communication disorders and the promotion of optimal development, which have been identified as primary roles for all professionals (ASHA, 1991). Owing to the prevalence of risk factors such as HIV/AIDS and poverty, infants and young children in developing countries such as South Africa are at an even higher risk for developing communication disorders, resulting in a greater need for early interventionists to focus on the prevention of communication disorders and the tools needed to achieve this. The purpose of this article is to (1) highlight the need for prevention of communication disorders and discuss the different types of prevention strategies used with special reference made to the needs within South Africa; (2) to highlight the potential benefits of caregiver education programs on communication development, including a discussion on a South African study that developed a tool that could be used for caregiver education; and (3) to encourage early interventionists to participate in prevention actions through the provision of practical guidelines and strategies.
Prevention of HIV-1 infection with early antiretroviral therapy

BACKGROUND Antiretroviral therapy that reduces viral replication could limit the transmission of human immunodeficiency virus type 1 (HIV-1) in serodiscordant couples. METHODS In nine countries, we enrolled 1763 couples in which one partner was HIV-1-positive and the other was HIV-1-negative; 54% of the subjects were from Africa, and 50% of infected partners were men. HIV-1-infected subjects with CD4 counts between 350 and 550 cells per cubic millimeter were randomly assigned in a 1:1 ratio to receive antiretroviral therapy either immediately (early therapy) or after a decline in the CD4 count or the onset of HIV-1-related symptoms (delayed therapy). The primary prevention end point was linked HIV-1 transmission in HIV-1-negative partners. The primary clinical end point was the earliest occurrence of pulmonary tuberculosis, severe bacterial infection, a World Health Organization stage 4 event, or death. RESULTS As of February 21, 2011, a total of 39 HIV-1 transmissions were observed (incidence rate, 1.2 per 100 person-years; 95% confidence interval [CI], 0.9 to 1.7); of these, 28 were virologically linked to the infected partner (incidence rate, 0.9 per 100 person-years, 95% CI, 0.6 to 1.3). Of the 28 linked transmissions, only 1 occurred in the early-therapy group (hazard ratio, 0.04; 95% CI, 0.01 to 0.27; P<0.001). Subjects receiving early therapy had fewer treatment end points (hazard ratio, 0.59; 95% CI, 0.40 to 0.88; P=0.01). CONCLUSIONS The early initiation of antiretroviral therapy reduced rates of sexual transmission of HIV-1 and clinical events, indicating both personal and public health benefits from such therapy.

Effectiveness of Ethylene Oxide and Gamma Irradiation on the Microbiological Population of Three Types of Paprika

The effectiveness of ethylene oxide and the gamma irradiation sterilizing treatments on the microbiological population was studied in three types of Spanish paprika, stored in a cold chamber (4°C) and at room temperature (16–36.8°C) over an experimental period of 285 days. The controlled microorganisms were: mesophilic aerobes, coliforms, sulfite reducing anaerobes, yeasts, molds, and Salmonella. The presence of aflatoxins was also studied. The results showed that both sterilizing treatments reduced the microbiological population to below the permissible levels recommended by the International Commission on Microbiological Specification for Food. Nevertheless, it was interesting that the gamma irradiation treatment was more effective.
