Using feature selection and association rule mining to evaluate digital courseware

Effective digital courseware should be easy to implement and integrate into instructional plans, saving teachers time and helping them support their students' learning needs. It should also not only enable students to achieve explicit learning objectives but also accelerate the pace at which they do so. This paper highlights the advantage of using Feature Selection techniques and Associative rule mining to get insightful knowledge from the log data from the Learning Management System (Moodle). The Machine Learning approach can be objectively deployed to obtain a predictive relationship and behavioral aspects that permits mapping the interaction behaviour of students with their course outcome. The knowledge discovered could immensely assist in evaluating and validating the various learning tools and activities within the course, thus, laying the groundwork for a more effective learning process. It is hoped that such knowledge would result in more effective courseware that provides for a rich, compelling, and interactive experience that will encourage repeated, prolonged, and self-motivated use.
An Ultra-Broadband GaN Doherty Amplifier with 83% of Fractional Bandwidth

This letter presents the design and characterization of an ultra-broadband GaN Doherty amplifier with more than an octave bandwidth. The developed architecture is based on ultra-wideband input/output splitting/combining networks capable to mitigate the typical frequency limiting factors of the traditional Doherty amplifier. The innovative design approach is demonstrated through a practical prototype realization based on commercial GaN-HEMT devices. From 1.05 to 2.55 GHz, continuous wave measurements have shown efficiency levels within 58% and 35% at 6 dB of output power back-off and within 83% and 45% at saturation, with an output power around 41 dBm. The performance of the prototype have also been evaluated by applying WiMAX and 3GPP modulated signals at different carrier frequencies, showing promising results.
Design of a multi-petawatt optical parametric chirped pulse amplifier for the iodine laser ASTERIX IV

A theoretical design is presented for the generation of peak powers up to /spl sim/5 PW and focused intensities higher than 10/sup 23/ Wcm/sup -2/ with pulse duration /spl sim/20 fs using an optical parametric chirped pulse amplifier (OPCPA) pumped by the high-power iodine laser Asterix IV. These values represent an improvement to the existing Asterix laser by a factor of /spl sim/1000 and at least LOO 000 for the output peak power and focused intensity, respectively. The OPCPA system consists of two LBO preamplifiers and a KDP power amplifier and is pumped by the laser third-harmonic output (438 nm, 500 ps, 500 J). Numerical simulations show that saturation within the OPCPA can be effectively used to counteract the bandwidth narrowing effects brought about by the temporal variation of the pump pulse intensity. The results demonstrate that the OPCPA represents a powerful technique for the generation of ultrahigh powers with iodine lasers at a level currently not achievable with any other approach, and proves that the iodine system is particularly suitable as an OPCPA pump source.
Development of scaffold for tissue engineering applications using imprinting

In this article we report the development of scaffold mimicking the cell surface topography. Using Soft lithography, in which polymer (triglyme, ethylene glycol dimethacrylate, methacrylic acid and IRGAcure 2022) is applied over the cultured cell and cured instantly using UV source. IRGA cure 2022 is a photoinitiator, which helps in solidification of the polymer when exposed to UV light source. Triglyme helps to increase the viscosity of the polymer. This method can be applied to all adherent cells. This scaffold consists of cell surface topography features. The developed scaffold can pave way in tissue engineering for various applications and cell research investigations.

Dynamic structures in phytoplasma genomes : sequence-variable mosaics ( SVMs ) of clustered genes

Emergence of the phytoplasma clade from an Acholeplasma-like ancestor gave rise to an intriguing group of cell wall-less prokaryotes through a remarkable and continuing evolutionary process. In a ceaseless progression, phytoplasmas have evolved reduced genomes, lost biochemical pathways for synthesis of nutrients supplied by hosts, and gained capabilities for transkingdom parasitism and pathogenicity in plants and insects. While continued genome degradation has made phytoplasmas increasingly host dependent, their small, AT-rich genomes have evolved conspicuous flexibility that enables rapid responses to host signals, successful evasion of host surveillance, and adaptation to shifting environments encountered during obligate, transkingdom parasitism. Recent work revealed that multiple, sequence-variable mosaics (SVMs) of clustered genes and repetitive extragenic palindromes are characteristic features of genome architecture in phylogenetically diverse phytoplasma species. SVMs are apparently of ancient origin, while current forms result from dramatic and more recent events. The dynamic nature of SVMs could account for their composite structure and potential for rapid changes significant in phytoplasma-host interactions.
Web API recommendation based on service cooperative network

Representational state transfer (REST) is the current design standard for Web Application Programmable Interfaces (Web APIs or APIs). Unfortunately, existing Web API search engines allow for only keyword or tag-based searches for RESTful services without considering advanced functionality, such as contextual recommendation or visualization. In this paper, we propose a novel approach, referred to as ServRel, to recommend relevant Web APIs based on the proposed service cooperative network for a target Web API. ServRel recommends users three kinds of RESTful services: competitive, pre-cooperative, and post-cooperative services for the selected services. Meanwhile, ServRel also displays the service cooperative network via the visualization technique to allow convenient browsing and accessing. The developed prototype fully demonstrates the feasibility and efficacy of the SerRel approach.
Soil seed banks in young, closed-canopy forests of the Olympic Peninsula, Washington: potential contributions to understory reinitiation

During early stand development, coniferous forests of the coastal Pacific Northwest commonly pass through a period of dense shade and intense competition during which the abundance and diversity of understory plants decline dramatically. In young, managed forests, silvicultural thinning has been proposed to enhance the structural and floristic diversity of the understory. Although germination of buried seeds is likely to be stimulated by thinning, we know little about the composition of the soil seed bank in these forests. We used the greenhouse emergence method to assess the potential contribution of the seed bank to understory reinitiation in 40- to 60-year-old, closed-canopy forests on the Olympic Peninsula, Washington. Seed banks were well developed (610-7009 germinants/m 2 ), containing 46 native and exotic species representing a diversity of life forms. However, many common forest understory species were absent; only 11 species were typical understory plants and these comprised <10% of all germinants. In contrast, 30% of all species and 50% of all germinants were exotic, ruderal forbs. Wind-dispersed annuals and perennials dominated litter samples, whereas ruderal forbs and graminoids with limited dispersal dominated soil samples. Our results suggest that silvicultural thinning will enhance the establishment of ruderal, exotic species but will contribute little to the regeneration from buried seed of the vast majority of forest understory plants.
Capture and rumination, functional avoidance, and executive control (CaRFAX): Three processes that underlie overgeneral memory

This article reviews the papers published in this Special Issue of Cognition and Emotion on Specificity in Autobiographical Memory. Together, the studies address some critical issues relating to the etiology of and mechanisms underlying the phenomenon of overgeneral memory. In terms of etiology, there is now substantial evidence of links between overgeneral memory and current or past depression, and between overgeneral memory and trauma history, and suicidal ideation and behaviour, independent of depression. In terms of mechanisms, three factors are emerging as the critical mechanisms underlying the phenomenon: Capture and rumination (CaR), functional avoidance (FA), and executive control dysfunction (X). Each of these has separately been found to produce overgenerality in memory; together they are almost certain to do so.
Instructions for use Title Two heterozygous mutations of the AMH gene in a Japanese patient with persistent Mullerian ductsyndrome

Persistent M ü llerian duct syndrome (PMDS) is an autosomal recessive disorder of sex development (DSD) characterized by the presence of M ü llerian duct derivatives in 46, XY phenotypic males. To date, more than 50 different mutations of the anti-M ü llerian hormone gene (AMH) have been reported. Here, we report two novel mutations of AMH in a Japanese patient with PMDS. A 1-year-old male presented with bilateral cryptorchidism and normal male external genitalia. A laparoscopic surgery revealed a uterus and fallopian tubes. Serum AMH was very low. The patient ’ s elder brother was also diagnosed as having PMDS at another hospital. Genetic analysis of AMH showed two novel mutations of p.N486T and p.V527L. Given that these two amino acids are well conserved among different species of AMH, the substitution of two amino acids might affect the normal function of AMH. In conclusion, PMDS should be included in differential diagnoses of cryptorchidism.
Targeting gene expression to endothelium in transgenic animals: a comparison of the human ICAM‐2, PECAM‐1 and endoglin promoters

Abstract: It is highly likely that successful pig‐to‐human xenotransplantation of vascularized organs will require genetic modification of the donor pig, and in particular of donor vascular endothelium. Promoters are generally tested in transgenic mice before generating transgenic pigs. Several promoters have been used to drive endothelial cell‐specific expression in mice but none have yet been tested in pigs. We compared the promoters of three human genes that are predominantly expressed in vascular endothelium: intercellular adhesion molecule 2 (ICAM‐2), platelet endothelial cell adhesion molecule 1 (PECAM‐1) and endoglin. Expression of human complement regulatory proteins (hCRPs), directed by each of the promoters in mice, was largely restricted to vascular endothelium and leukocyte subpopulations. However, expression from the PECAM‐1 promoter was weak in liver and non‐uniform in the small vessels of heart, kidney, and lung. Conversely, expression from the endoglin promoter was consistently strong in the small vessels of these organs but was absent in larger vessels. The ICAM‐2 promoter, which produced strong and uniform endothelial expression in all organs examined, was therefore used to generate hCRP transgenic pigs. Leukocytes from 57 pigs containing at least one intact transgene were tested for transgene expression by flow cytometry. Forty‐seven of these transgenic pigs were further analyzed by immunohistochemical staining of liver biopsies, and 18 by staining of heart and kidney sections. Only two of the pigs showed expression, which appeared to be restricted to vascular endothelium in heart and kidney but was markedly weaker than in transgenic mice produced with the same batch of DNA. Thus, in this case, promoter performance in mice and pigs was not equivalent. The weak expression driven by the human ICAM‐2 promoter in pigs relative to mice suggests the need for additional regulatory elements to achieve species‐specific gene expression in pigs.
High-Capacity and Dispersionless Delay Lines Based on Plasmonic Waveguide Periodically Coupled With Bilaterally Located Ring and Slot Resonators

We propose and study optical delay lines with high capacity and low dispersion based on a plasmonic waveguide periodically coupled with bilaterally located ring and slot resonators. The repetitive unit exhibits plasmon-induced transparency (PIT) with a large delay-bandwidth product due to the interference between the two-mode ring and single-mode slot resonators. By choosing appropriate parameters, the cascaded PIT units can possess a broad transparency window with moderate fluctuations and produce wideband dispersionless slow light. A theoretical model is developed to analyze the proposed structure and the results are validated by finite-difference time-domain simulations. The pulse propagation results indicate that the spectral fluctuations have a negligible effect on the delayed pulse shape. Using multiple cascaded PIT units, we demonstrate that the group index of the waveguide approaches 36, the 3-dB bandwidth is larger than 21 nm, and a storage efficiency of 0.5 bit/unit can be realized with negligible distortion. Due to the high performance, the proposed delay line may find potential applications in future nanoscale integrated photonic systems.
Body MR imaging and CT volume: variations and trends based on an analysis of medicare and fee-for-service health insurance databases.

OBJECTIVE We examined Medicare and fee-for-service data sets to understand better the utilization of MR imaging for imaging the pelvis, abdomen, and chest relative to its use in imaging for other body parts and to the utilization of CT. MATERIALS AND METHODS CT and MR imaging procedure volumes for pelvis, abdomen, chest, and total were extracted from the 1993, 1996, and 1999 Health Care Financing Administration Physician/Supplier Procedure Summary Master Files, based on CPT-4 codes. We also analyzed a fee-for-service health insurance database for January 1998 through July 1999 from a single northeastern state, which included provider location (rural, suburban, or urban) and type (teaching or nonteaching site). RESULTS The greatest 3-year Medicare increase was for abdominal MR imaging, from 1996 to 1999 (101% increase). However, pelvic, abdominal, and chest MR imaging together remained less than 5% of total MR imaging. Abdominal MR imaging increased more than did total MR imaging in all 10 Health Care Financing Administration regions. In the fee-for-service database, the relative procedure volume of abdominal MR imaging varied approximately fivefold from rural to urban provider locations, and approximately double from nonteaching to teaching hospitals. CONCLUSION Although far more abdominal CT than abdominal MR imaging is performed, the rate of abdominal MR imaging utilization has increased more rapidly since 1993. The relative procedure volume of abdominal MR imaging varied more than fivefold from rural to urban provider locations and double from nonteaching to teaching hospitals.
Evaluation of Platelets Count and Indices in Pre-Eclampsia Compared to Normal Pregnancies

Background/Aim: Pre-eclampsia (PE) and eclampsia are major obstetric problem in developing countries and remains an important cause of maternal mortality worldwide. The study aimed to evaluate/compare the platelet count and platelet indices in pre-eclampsia and normal pregnancies Methods: This prospective case control study was conducted in Khartoum state at Omdurman Maternity Hospital, during the period from March to June 2016. Pregnant women (N/87) with 28 weeks’ gestation or more who attended at antenatal care unit or admitted into the Department of Obstetrics and Gynecology, were selected as population of the study. Among them 37 patients with either mild or sever PE, 50 normal pregnancies as controls were enrolled. EDTAvenous blood sample was collected from each patient and control for platelet count and platelet indices measurement by automated blood cells counter (SYSMEX-KX 21). Results: In the present study the mean platelet counts was 236.16±82.33, 261.34 ±62.69 X10 9 /L in patients and controls respectively. The mean MPV was 10.15±1.10 and 9.48±0.87/fl, whereas mean PDW was 13.37±2.84, 12.15±2.35 /fl as well as mean P-LCR% was 26.71±7.87, 22.32±6.52% in patients and controls respectively. The present study found that MPV(P; 0.02), PDW (P; 0.03) and P-LCR (P; 0.05) of PE group was significantly higher than normal group. The platelets count (P; 0.1) and plateletcrit (PCT%) (P; 0.64) were lower in PE group but didn’t show significant variation. Conclusion: Platelet indices of MPV, PDW and P-LCR increases in PE in comparison to normal pregnancy Key.
Update on Head and Neck Cancer: Current Knowledge on Epidemiology, Risk Factors, Molecular Features and Novel Therapies

Tobacco use and alcohol consumption are the main risk factors associated with head and neck squamous cell carcinoma (SCC) development due to their cytotoxic and mutagenic effects on the exposed epithelia of the upper aerodigestive tract. Epstein-Barr virus (EBV) and high-risk human papillomaviruses (HPVs), both encoding viral oncoproteins able to interfere with cell cycle control, have been recognized as the etiological agents of nasopharynx carcinoma and a fraction of oropharyngeal carcinoma, respectively. Head and neck SCC is a deadly disease and despite innovative treatments represents a major challenge for patients. Recently, a number of genomic studies have highlighted the molecular heterogeneity of head and neck SCC based on methylation profiles, microRNA expression, mutated genes and new druggable pathways which may represent new targets for cancer-tailored therapies. To date, cetuximab is the only FDA-approved anti-epidermal growth factor receptor therapy for the treatment of head and neck SCC. In addition, a number of monoclonal antibodies targeting AKT, mTOR and PI3K pathways are under evaluation. Several therapeutic vaccines against HPV16 and EBV proteins are also under study. The purpose of this article is to review the epidemiology, pathogenesis and molecular features of head and neck SCC, with an emphasis on new therapies.
On implementing transforms from integers to integers

Arbitrary linear transforms are often applied to integer valued data sequences, producing non-integer outputs. In such cases, it is often desirable to approximate the true transform with a non-linear transform producing integer outputs as close as possible to the true transform, while retaining the reversibility property of a transform. This paper proposes a new approach to implement transforms that map integers to integers in a reversible way. The approach aims to develop a reversible implementation that minimizes the average distortion between the integer outputs and the outputs of the true linear transform.
Learn To Rate Fine Food

We investigate a food review dataset from Amazon with more than 500000 instances, and utilize information from the data set such as the text review, score, helpfulness, etc. Instead of the traditional word representation using frequency, we use skip-gram to train our own word vectors using the pretrained GloVe Twitter word vector as the initialized value. We also use recursive parsing tree to train the vector of the whole sentence with the input of word vectors. After that, we use neural network methods to classify our review text to different scores. We mainly research and compare the performance of Gated Recurrent Unit Network (GRU) and Convolutional Neural Network (CNN) on our data. After tuning the hyper parameters, we get our best classifier as a bi-directional GRU. We also build a Long Short Term Memory Model (LSTM) for text generation, which is able to generate text for each score level. Then we build a recommendation system based on Latent Factor Model, with Stochastic Gradient Descent, and recommend 10 items to selected users. Finally, we use softmax regression to visualize the most important words for a certain score, and design a spam review binary classification based on the helpfulness scores of the reviews.
Development of consumer credit in China

Consumer credit – particularly personal consumer loans such as home mortgages and loans financing purchases of automobiles and large durable goods – has developed at a very rapid pace in China over the past decade. With the deepening reform of the house market beginning in 1998, commercial banks began to extend mortgage loans to individuals seeking to buy their own homes. Mortgage loans are now among the best assets held by China’s commercial banks. However, China’s policymakers and regulators are still facing challenges, including a nascent economy-wide credit information system, financial institutions with varying risk management standards and, in recent years, surging house prices. Therefore, in the context of China’s macroprudential policies, the Chinese regulatory authorities have adopted a series of mortgage-related policies and regulations to mitigate and control credit risks and facilitate the healthy development of housing finance, home ownership and housing markets.
Palm vein recognition scheme based on an adaptive Gabor filter

We propose a novel palm vein recognition scheme based on an adaptive 2D Gabor filter. Three key steps were studied in this scheme: region of interest (ROI) extraction, adaptive Gabor filtering, and template matching. First, in the palm vein image extraction step, the authors used the index finger on both sides of the valley to locate the square area, and then iteratively expanded the area of the square box to maximise the ROI. Second, in the feature extraction step, a novel parameter selection scheme was proposed for optimising the Gabor filter. Third, in the template matching step, the author presented a novel template matching algorithm referred to as the minimum normalised Hamming distance. Experimental results demonstrated that the scheme achieved good performance with an EER of 0.12%.
