Teacher Adoption of Web-based Learning in Blended Environment

Abstract . Because of the significant benefits to be gained from Internet technology, many educational institutions have brought in online learning management systems to their traditional classroom courses. The emergence of blended instruction allows teachers to integrate the advantages of face-to-face classroom interactions with positive attributes of distance learning. Nevertheless, the value of the blended approach relies heavily on the teachers’ adoption of the add-on platform. In view of the fact that individual perception has a very real impact on behavior, this paper explores the teachers’ preconceptions about web-based learning system in blended environment. Data were collected via interviews with nine teachers from a tertiary institution about their authentic experiences and viewpoints on an e-learning platform, and were analyzed qualitatively using the approach of phenomenography. Altogether, there emerged nine categories of descriptions on teachers’ perception. The future of blended learning will most likely be determined by how teachers are able to arrive at a good balance between the tradition and the technology. An understanding of the teacher’s perception is crucial to provide insight on successful implementation. The paper ends with the discussion on the implications drawn out from the findings.
Genetic Inactivation of DNMT3b Protects Against Activation of Osteogenic Signaling and Slows Progression of Aortic Valve Stenosis in Mice

While recent work from our laboratory showed that DNA (cytosine‐5)‐methyltransferase 3 beta (DNMT3b) is significantly increased in tissue from humans with calcific aortic valve stenosis and is associated with increases in global genomic methylation, it is unknown whether the net effects of these changes are protective or deleterious. The objective of this study was to test the hypothesis that genetic reduction of DNMT3b allows for increased anti‐osteogenic gene expression, and consequently results in suppression of osteogenic signaling and slower progression of valvular stenosis.
Readmissions among People Living with HIV Admitted for Hypertensive Emergency

Patients living with human immunodeficiency virus are at increased risk of developing cardiovascular diseases. Hypertensive emergency, a complication of hypertension with potentially serious health implications, has high healthcare utilization. Using the Nationwide Readmissions Database, the authors evaluate a key population that would benefit from identifying patients at the highest risk of rehospitalization to allow for targeted intervention to better understand and decrease readmissions caused by hypertensive emergency in patients with human immunodeficiency virus. Abstract Objectives People with human immunodeficiency virus (HIV) are at an increased risk of developing cardiovascular diseases. Hypertensive emergency (HTNE), a complication of hypertension with potentially serious health implications, has high healthcare utilization. We attempted to determine the association between HIV status and risk for 30-day readmission after index hospitalization for HTNE. Methods We used the Nationwide Readmissions Database to identify all of the admissions during 2010–2017 with a primary discharge diagnosis of HTNE. Admissions were stratified by HIV status and comparisons were made with the χ2 test. We investigated predictors of all-cause 30-day readmission via multivariable logistic regression. Results A total of 612,854 hospitalizations with a primary discharge diagnosis of HTNE were identified, and 4115 (0.7%) were HIV positive. There was a total of 43,937 (7.16%) 30-day readmissions, and the rate was higher in regard to positive HIV status (29.8% vs 15.0%; P < 0.001). Renal failure was the most frequent reason for HIV readmissions and the second most frequent reason for non-HIV readmissions (15.6% vs 10.3%; P < 0.001). In contrast, heart failure was the most frequent reason for non-HIV readmissions and the second most frequent reason for HIV readmissions (10.3% vs 11.9%; P = 0.234). There was a higher median cost for HIV readmissions in comparison to non-HIV readmissions ($7660 vs $7490; P < 0.001). Finally, HIV was attributed to 40.6% increased odds of readmission after adjusting for pertinent clinical and demographic factors (P < 0.001). Conclusions HIV-positive status is associated with an increased risk for 30-day readmission after index hospitalization for HTNE.
The BH3 domain of Bax is essential for regulating its solubility and mitochondrial targeting

The pro‐apoptotic protein Bax plays an important role in apoptosis regulation. In response to many apoptotic stimuli, Bax translocates from cytosol to mitochondria and triggers mitochondrial dysfunctions. The BH3 domain of Bax (a.a 59–73) has been identified to be an essential domain of the protein. It enables Bax bind to the pro‐survival protein Bcl‐2 or Bcl‐XL and has been shown to be important for its death‐prohibitory property.

Indoors positioning through VLC technology using an a-SiC:H photodetector

The work presented in this paper supports the viability of a navigation system based on Visible Light Communication (VLC) for indoors applications. The system design uses RGB LEDs and an a:SiC:H photodetector. An optoelectronic characterization of the devices used in the integrated system is presented to support the main results, namely the decoding strategy. The photodetector is a pin-pin heterostructure that works as an optical filter, presenting a selective spectral sensitivity dependent on the external optical bias. The red and blue light emitted from the white RGB LEDs were modulated at different frequencies. With this configuration each cardinal direction becomes assigned to a specific set of optical excitation (wavelength and frequency). The decoding of the output photocurrent allows the identification of the input optical signals and the determination of the correspondent spatial direction. The localization algorithm makes use of the Fourier transform to identify the frequencies present in the photocurrent signal and the wavelength filtering properties of the sensor under front and back optical bias to detect the existing red and blue signals. The viability of the system is demonstrated through the implementation of an automatic algorithm to infer the photodetector cardinal direction. Additional research on the light intensity is presented to investigate the accuracy of the spatial position along a cardinal direction.
Using low-grade hardwoods for CLT production: a yield analysis

Low-grade hardwood logs are the by-product of logging operations and, more frequently today, urban tree removals. The market prices for these logs is low, as is the value recovered from their logs when producing traditional forest products such as pallet parts, railroad ties, landscaping mulch, or chips for pulp. However, the emergence of cross-laminated timber (CLT) for building construction in North America may provide an additional and possibly a more valuable product market for low-grade, low-value hardwood logs. Using the RaySaw sawing and ROMI rough mill simulators and a digital databank of laser-scanned low-grade yellow-poplar (Liriodendron tulipifera) logs, we examine the yield-recovery potential for lumber used in the production of CLT.

The Relationship Between Whole Grain Consumption and Body Measures in American Children Ages 6‐18 Years: Results From NHANES 1999‐ 2004

One‐day food intake from NHANES 1999‐04 coupled with the MyPyramid Equivalents Database, 2.0 for USDA Survey Foods was used to estimate whole grain (WG) intake of children ages 6‐18 years (n=8695). Weighted data were analyzed using SUDAAN. Children with a reported BMI were classified into groups based on their WG intake: 0 ounce equivalents (oz. eq.), >0 & <1 oz eq and >=1oz eq per day. BMI Z‐score, waist‐to‐height ratio (WHR) and percent overweight/obese were compared across groups. Children in the highest WG group had significantly lower unadjusted BMI Z‐scores and WHR than the lower 2 WG groups (p<0.005) and a significantly lower percent overweight/obese than the 0 WG group (p=0.002). Regression modes for BMI Z‐score and WHR as a of WG groups intake adjusted for age, gender, ethnicity, energy, physical activity and dietary fiber showed a significant predicted decrease in BMI Z‐Score with increasing WG intake (p<0.01). A logistic regression model adjusted for the same variables predicted a decline in percent overweight/obese with increasing WG intakes (p=0.07). Major sources of WG included ready‐to‐eat cereals (38% of total intake), grain snacks (24%) and yeast breads (18%). These data suggest increased WG intake may contribute to a healthy body measures in American children.
Supply Chain Integration and Performance: A Literature Review

The purpose of this article is to provide an overview of the literature covering the area of Supply Chain Integration (SCI), Supply Chain Performance (SCP) and other Supply Chain Management Factors (OSCMFs) in Supply Chain Management (SCM). Supply Chain Integration (SCI) is considered one of the major factors in improving supply chain performance. It is provoked by the increasing attention the two fields of SCI and SCP have recently attained, stimulated by an augmenting competitive pressure companies are facing. For supply chain practitioners to realize the existing potentials, effective SCI are necessary. In order to facilitate future research in the field of SCI, which consequently also benefits practitioners; it is necessary to consolidate the extant literature. To do so and to identify promising avenues for future research is the purpose of this article. We provide a literature review that covers the main aspects of SCI, SCP and OSCMFs in context of SCM. To account for quality of publication, the analysis is restricted to top international journals.
A novel inducible mutagenesis system in Mycobacterium tuberculosis

In Mycobacterium tuberculosis (Mtb), damage‐induced mutagenesis is dependent on the C‐family DNA polymerase, DnaE2. Included with dnaE2 in the Mtb SOS regulon is an operon comprising Rv3395c, which encodes a protein of unknown function, and Rv3394c, which is predicted to encode a Y‐family DNA polymerase. Our results show that Rv3395c (designated imuA′) and Rv3394c (imuB) are individually essential for induced mutagenesis and damage tolerance and that ImuB interacts with both ImuA′ and DnaE2, as well as with the β‐clamp. Disruption of the ImuB‐β clamp interaction significantly reduces induced mutagenesis and damage tolerance, phenocopying deletion mutants in imuA′, imuB, and dnaE2. Despite retaining structural features characteristic of Y‐family members, ImuB homologs are pseudo‐polymerases which lack conserved active‐site residues. In contrast, mutation of catalytic, aspartate residues in DnaE2 reproduces the dnaE2 gene deletion phenotype, implicating this polymerase in mutagenic lesion bypass. Together, these results identify the split imuA′‐imuB/dnaE2 cassette as a compelling target for compounds designed to limit mutagenesis in a pathogen increasingly associated with drug resistance
ZERO-KNOWLEDGE PROOFS FROM SPLWE-BASED COMMITMENTS

Recently, an LWE-based commitment scheme is proposed. Their construction is statistically hiding as well as computationally binding. On the other hand, the construction of related zero-knowledge protocols is left as an open problem. In this paper, we present zero-knowledge protocols with hardness based on the LWE problem. we show how to in-stantiate eﬃcient zero-knowledge protocols that can be used to prove linear and sum relations among these commitments. In addition, we show how the variant of LWE, spLWE problem, can be used to instantiate eﬃcient zero-knowledge protocols.
Low Complexity Video Coding on Block based Singular Value Decomposition (SVD) Algorithm

This paper presents analysis of video compression based on block SVD Algorithm. Compression is done to reduce the volume of data to be transmitted, to reduce the bandwidth required for transmission and to reduce the storage requirements. Video is a sequence of still images representing scenes in motion. Current video compression standards like MPEG, H.26x series are highly computationally expensive and hence they are not suitable for real time applications. Current applications like video calling, video conferencing require low complexity video compression algorithms. In addition, the paper investigates the effect of rank in block SVD decomposition to measure the quality in terms of compression ratio and PSNR and also reduce the complexity. The advantage of using the block SVD is the property of energy compaction and its ability to adapt to the local statistical variations of an image.
Application of hybrid framework to facilitate lean six sigma implementation: a manufacturing company case experience

Abstract This study aims to propose a hybrid framework for lean six sigma (LSS) based on the prioritisation of barriers and solution approaches, to facilitate hassles free applications for handling the challenges of wastes reduction and quality improvement. The study identifies 27 LSS barriers and 22 solution approaches through literature review and utilises feedback from industry experts. For framework, study uses fuzzy AHP-PROMETHEE to prioritise LSS barriers and solution approaches. Incorporating fuzzy sets in analytical hierarchy process (AHP) ensures the optimality of barrier weights. Whereas, preference ranking organisation method for enrichment of evaluations (PROMETHEE) helps in pairwise comparisons of solution approaches with respect to each LSS barrier, facilitating fair judgements. This research guides regarding the development of framework and checks its suitability and robustness through case application of an Indian manufacturing organisation. Authors expect that researchers and practitioners will find study useful for LSS and multi criteria decision making(MCDM) domains.
Digital Technologies as External Enablers of New Venture Creation in the IT Hardware Sector

We develop theory about how and when digital technologies enable new venture creation processes. We identify two fundamental properties of digital technologies—specificity and relationality—and develop propositions that link these properties to six enabling mechanisms: compression, conservation, expansion, substitution, combination, and generation. We use the linked properties and mechanisms to determine how and when in the venture creation process—from prospecting to developing to exploiting—digital technologies have enabled start-ups in the IT hardware sector and develop stage-dependent propositions about their sector-level effects. We conclude our theorizing by discussing its implications beyond digital technologies and the IT hardware sector.
Permeability Study of Functionally Graded Scaffold Based on Morphology of Cancellous Bone

Introduction: Natural cancellous bone consists of inhomogeneous structures in which the porosity or pore size changes spatially. It becomes more challenging to exploit the potential of the designed scaffold to describe the complexity of bone architecture. In order to mimic cancellous bone architecture, a functionally graded scaffold (FGS) and uniform model based on pillar and hexagon unit cells have been successfully developed by using a Computer-Aided Design (CAD). This study aimed to determine the permeability of FGS and uniform scaffolds associated with the ability of cells to penetrate porous media. Methods: FGS and uniform scaffold were modelled based on the morphology of cancellous bone in bovine femoral condyle associated with porosity, Tb.Th, Tb.Sp, and BS/TV. The permeability and fluid movement through the scaffolds were analyzed using computational fluid dynamics. Results: The results show that the uniform scaffold has a strong correlation where the porosity increases, the permeability also increases. On the contrary, when the specific surface area increases, the permeability decreases significantly. When viewed on the scaffold PFGS and HFGS with 12NUC do not show a unique correlation, where the permeability value is proportional to the porosity level. Additionally, controlling NUC can be increasing BS/TV value. Conclusion: From the results explained in scaffold designing, it can mimic the morphology of cancellous bones such as Tb.T, Tb.Sp and BS/TV. It can be concluded that scaffold designed has fulfilled the requirements for the ideal scaffold because permeability value of the overall scaffold in the range of the cancellous bone.
Predicting Doctor Ratings from User Reviews using Deep Learning

An increasing number of doctor reviews are being generated by patients on the internet daily. Individuals more often turn to the internet to find and exchange health-related data, and this predilection has resulted in a profusion of user yielded health-related material, particularly web-based physician ratings and reviews. Doctor evaluation websites can encourage people to make more considered decisions when it comes to seeking healthcare professionals for quality treatment. We aim to complete an extensive analysis of online doctor reviews and examine patient (dis)satisfaction based on doctor enforcement reviews and forecast their numeric ratings. We have analyzed over 12000 patient reviews for around 530 doctors.
Design of a Real-Time Movement Decomposition-Based Rodent Tracker and Behavioral Analyzer Based on FPGA

In this work, a real-time movement decomposition-based automatic behavior analysis system is proposed. The proposed method is evaluated on a Morris water maze experiment with rat. The system integrated a high-speed tracker, a feature extraction module, and a classifier on a Xilinx Ultra-96 single computer board with a field-programmable gate array (FPGA). The high-speed tracker includes a movement predictor based on motion features and pose features, and a fast-checking algorithm to evaluate whether the tracking result is correct or not. A faster region-based convolutional neural network (Faster-RCNN)-based detector is used for initializing the tracker. The feature extraction module integrated a CNN-based feature point recognition network and a motion feature computing module. Motion and pose feature are calculated with the result of the feature points. The proposed system achieves a 66.2-frames/s processing speed, and the average point detection error is 4.01 pixels. For each video, the classification and regression tree (CART)-based classifier gives an explorative stage in five categories, which represents the rat’s strategy of exploration in Morris water maze task. This work focuses on a real-time local computing system design on small-scale datasets.
