Energy-aware scheduling scheme using workload-aware consolidation technique in cloud data centres

To reduce energy consumption in cloud data centres, in this paper, we propose two algorithms called the Energy-aware Scheduling algorithm using Workload-aware Consolidation Technique (ESWCT) and the Energy-aware Live Migration algorithm using Workload-aware Consolidation Technique (ELMWCT). As opposed to traditional energy-aware scheduling algorithms, which often focus on only one-dimensional resource, the two algorithms are based on the fact that multiple resources (such as CPU, memory and network bandwidth) are shared by users concurrently in cloud data centres and heterogeneous workloads have different resource consumption characteristics. Both algorithms investigate the problem of consolidating heterogeneous workloads. They try to execute all Virtual Machines (VMs) with the minimum amount of Physical Machines (PMs), and then power off unused physical servers to reduce power consumption. Simulation results show that both algorithms efficiently utilise the resources in cloud data centres, and the multidimensional resources have good balanced utilizations, which demonstrate their promising energy saving capability.
BUILDING AN ASSISTANT MOBILE APPLICATION FOR TEACHING ARABIC PRONUNCIATION USING A NEW APPROACH FOR ARABIC SPEECH RECOGNITION

The Arabic language is characterized by its vocal variations. Making its pronunciation a difficult task for Arabic learners. In this paper, we show how we built a mobile application that can detect mispronounced words and guide the user to the correct pronunciation. Foreigners and children can learn Arabic pronunciation in a friendly manner using our application. Our mobile application is customized to help them learn The Holy Quran recitation in particular. The process of the application compares the user sound (sound signal) of a single word with the set of correct recordings of this word pronunciation. This paper proposes the use of MFCC features to extract features from the speech signal. It also demonstrates the use of a modified version of DTW algorithm to compare the features of the user and the teacher.
Am I an Online Shopper After All? A Paradox on Definition of e-Commerce from the Consumers' Perspective

Retailing marketplace today is composed of traditional and electronic retailers. Facing to the evolutionary transformation arose from electronic commerce (EC), this article attempts to establish the elementary understanding on EC and modern consumers’ behavior. The authors examine the gap between practitioners’ and academics’ perception about EC and get a clear look from consumers’ perspective. Four behavioral patterns with different tendency to online activities are further identified. They are product-, price-, convenience-, and service-orientation. Additionally, an industrial demonstration of consumer electronics retailing is presented to show the gap and to exemplify an application of consumers’ behavioral patterns proposed in this paper. For people involved in the marketing and EC fields, this article suggests that consumer behavior should be reexamined according to the specific product categories under appropriate EC definition.
Study of the Skin of a New Hairless Rat Mutant

Histological and immunological examinations were performed on the skin of a newly established strain of hairless rat (Hirosaki hairless rat; HHR). The appearance of the mutant rat skin was marked by resembles to human skin with wrinkles and scarce vellus hair. The presence of scattered dilated follicular cysts in the mid‐dermis was the most predominant microscopic change. Electron microscopically, some of the basal cells contained many oval organelles in the cytoplasm, although their role was not clear. Langerhans cells were observed, but melanocytes were lacking in the epidermis. Immunofluorescence technique demonstrated Ia‐positive cells (presumably Langerhans cells) in epidermal sheets from the soles of the mutants, which also developed contact sensitivity to dinitrochlorobenzene (DNCB). HHRs may be a useful experimental model for studies of allergic as well as nonallergic dermatitis requiring gross observation and wrinkled skin.
20-Mb/s GFSK Modulator Based on 3.6-GHz Hybrid PLL With 3-b DCO Nonlinearity Calibration and Independent Delay Mismatch Control

A hybrid two-point modulator which mitigates the nonlinearity problem of a digitally controlled oscillator (DCO) and provides a fine delay mismatch calibration is proposed for high data rate applications. A DCO with a separate high-pass modulation path in which only 3 b are used for a capacitor array is designed for flexible gain partition and simple nonlinearity calibration. A nonuniform multilevel quantizer and a finite-impulse response filter are employed to improve modulation quality and reduce quantization noise for high data rate. In the low-pass modulation, a fractional-<inline-formula> <tex-math notation="LaTeX">${N}$ </tex-math></inline-formula> divider based on a phase rotator and an additional high-frequency <inline-formula> <tex-math notation="LaTeX">$\Delta \Sigma $ </tex-math></inline-formula> modulator enables fine delay time control between two modulation paths. Delay mismatch calibration circuit based on a time-to-digital converter is designed to calculate the optimum delay time automatically. A prototype 3.6-GHz two-point modulator is implemented in 65-nm CMOS. The modulator performs 20-Mb/s GFSK with the error vector magnitude performance of 3.7%, consuming 10.6 mW from a 1-V supply.
Opportunistic power allocation for point-to-point communication in self-organized networks

In this paper, we study the performance of point-to-point communication in self-organized networks. An information-theoretic framework is considered to determine the optimum transmission power enabling reliable communication between neighboring nodes at a certain user requested rate. Realistic channel models taking into account path-loss and fading are also considered. Optimal power allocation strategies are investigated. For this purpose, we use the ergodic capacity as a criterion for information-theoretic analysis. In the first case, the transmit power is the same for all pairs. In a more opportunistic case, different transmit pairs use different transmit powers according to their channel realizations. Then, for a given rate requirement C, we derive the optimal close-talker distance that meets the requirement for a given power P. Numerical results are finally presented giving insights into the design of power adaptation schemes for point-to-point communications.
A Soft-Switching DC/DC Converter With High Voltage Gain

A soft-switching dc/dc converter with high voltage gain is proposed in this paper. It provides a continuous input current and high voltage gain. Moreover, soft-switching characteristic of the proposed converter reduces switching loss of active power switches and raises the conversion efficiency. The reverse-recovery problem of output rectifiers is also alleviated by controlling the current changing rates of diodes with the use of the leakage inductance of a coupled inductor. Experimental results obtained on 200 W prototype are discussed.
A Cooperative Content Distribution System for Vehicles

For vehicle users, content distribution through roadside APs is an important complement to that through 3G and other cellular networks. However, the unique features of such access scheme pose many challenges on effectively satisfying vehicles' data request. This paper proposes a cooperative content distribution system for vehicles(CCDSV), based on the network-coding, vehicle-AP contact prediction, and data-prefetching techniques. CCDSV uses network coding to distribute encoded data for the effective sharing of popular contents. CCDSV predicts the vehicle's future contact APs and adaptively prefetches requested data in advance before vehicle's arrival. The proposed system is implemented into ns-2 simulator and demonstrates its effectiveness in terms of throughput, reduced traffic load, and download volume.
Bankart ARTHROSCOPIC VERSUS OPEN STABILIZATION FOR TRAUMATICANTERIOR SHOULDER INSTABILITY : ACOMPARISON OF CLINICALOUTCOMES

With the advance of arthroscopic surgical technique and instruments, minimal invasive arthroscopic reconstruction has become preferred treatment method for Bankart reconstruction. The aim of this study was to describe surgical technique and report the results after either open or arthroscopic Bankart shoulder stabilization in a retrospective series with a medium-term follow-up. We performed a retrospective study comprising 43 patients (43 shoulders) with symptomatic, traumatic anterior shoulder instability to compare open versus arthroscopic reconstruction. Twenty eight arthroscopic reconstructions and fifteen open reconstructions were performed using metal suture anchors.All of the patients had the Bankart lesion. Independent observers examined the shoulders at a median follow-up period of 41.1 months (range, 16 to 57) for the arthroscopic group and 68.1 months (range, 51 to 113) for the open group. The recurrence rate was two of 15 (13%) in the open group and 7.1% (2 out of 28) in the arthroscopic group. During the follow-up, the Rowe score was 84.3 points (range, 39 to 100) in the open group compared with 87.3 points (range, 53 to 100 for the Rowe scores, respectively) in the arthroscopic group. Both methods produced stable and well-functioning shoulders in the most of patients with the Bankart lesion. Although the arthroscopic technique can lead to a higher recurrence rate, better results were attained for external rotation of the shoulder in the patients treated with this minimally invasive technique.
Epidermal Phytochrome B Inhibits Hypocotyl Negative Gravitropism Non-Cell-Autonomously

Epidermal phyB non-cell-autonomously promotes the degradation of endodermal PIFs to inhibit hypocotyl negative gravitropism. Seedling hypocotyls display negative gravitropism in the dark but agravitropism in the light. The Arabidopsis thaliana pif quadruple mutant (pifQ), which lacks four PHYTOCHROME-INTERACTING FACTORS (PIFs), is agravitropic in the dark. Endodermis-specific expression of PIF1 rescues gravitropism in pifQ mutant seedlings. Since phytochromes induce light responses by inhibiting PIFs and the COP1-SPA ubiquitin E3 ligase complex in the nucleus, we asked whether phyB can cell autonomously inhibit hypocotyl negative gravitropism in the endodermis. We found that while epidermis-specific expression of PHYB rescues hypocotyl negative gravitropism and all other phyB mutant phenotypes, endodermis-specific expression of PHYB does not. Epidermal phyB induces the phosphorylation and degradation of endodermal PIFs in response to red light. This induces a global gene expression pattern similar to that induced by red light treatment of seedlings expressing PHYB under the control of its own endogenous promoter. Our results imply that epidermal phyB generates an unidentified mobile signal that travels to the endodermis where it promotes PIF degradation and inhibits hypocotyl negative gravitropism.
Hierarchical model of gene regulation by transforming growth factor β

Transforming growth factor βs (TGF-βs) regulate key aspects of embryonic development and major human diseases. Although Smad2, Smad3, and extracellular signal-regulated kinase (ERK) mitogen-activated protein kinases (MAPKs) have been proposed as key mediators in TGF-β signaling, their functional specificities and interactivity in controlling transcriptional programs in different cell types and (patho)physiological contexts are not known. We investigated expression profiles of genes controlled by TGF-β in fibroblasts with ablations of Smad2, Smad3, and ERK MAPK. Our results suggest that Smad3 is the essential mediator of TGF-β signaling and directly activates genes encoding regulators of transcription and signal transducers through Smad3/Smad4 DNA-binding motif repeats that are characteristic for immediate-early target genes of TGF-β but absent in intermediate target genes. In contrast, Smad2 and ERK predominantly transmodulated regulation of both immediate-early and intermediate genes by TGF-β/Smad3. These results suggest a previously uncharacterized hierarchical model of gene regulation by TGF-β in which TGF-β causes direct activation by Smad3 of cascades of regulators of transcription and signaling that are transmodulated by Smad2 and/or ERK.
Diagnosis of Pediatric Cholesteatoma

Cholesteatomas are abnormal collections of squamous epithelium and keratin debris that usually involve the middle ear and mastoid. Although histologically benign, they have the ability to expand and destroy bone. Cholesteatomas are treated surgically. The success of such surgery is highly dependent on the extent of the lesion. This article presents information and images to aid the general pediatrician in the early recognition of cholesteatomas, both congenital and acquired, in hopes of improving the outcome for children with this treatable disorder.
An integrated design method for machine and assembly cell formation

The object of this study is to propose an integrated design method for machine-part grouping problem and part-assembly grouping problem in cellular manufacturing system design using mathematical programming procedure. There is a great deal of methods that have been proposed for the machinepart grouping problem in cellular manufacturing system. But few researches consider the design for machine cell and assembly cell simultaneously. The product considered in this study is assumed to be assembled with several parts which are manufactured through machining processes. It is necessary to convey the parts from machine cell to assembly cell smoothly. Therefore we consider machine cell and assembly cell formation concurrently. Relation of the assembly products and parts are shown by assembly-part incident matrix same as machine-part incident matrix. Using these two incident matrices, machines and assembly products also can be shown by a matrix. Grouping efficacy is a good grouping index for machine-part incident matrix which consists of 0 and 1 elements. We propose a new grouping efficacy for machine-part-assembly incident matrix, because the matrix has the element value larger than 1. Last we show several numerical examples using the proposed method and evaluate the results by the proposed grouping efficacy.
Compact reconfigurable ceramic filter based on combline type 3-D resonators

In this paper compact ceramic filters, based on the principle of combline filters, are proposed. These filters offer a very good tradeoff between size and performances while offering a wide spurious free region. Two different filters are proposed here: a fixed frequency (X-band) and a tunable 5 pole Chebyshev. The expected frequency coverage is close to 56% f0.
Mutation is required to activate the p53 gene for cooperation with the ras oncogene and transformation

Previous experiments have brought into question which amino acid sequence of the p53 oncogene product should be considered wild type and whether the normal protein is capable of cooperating with the ras oncogene to transform cells in culture. To address these questions, a series of p53 cDNA-genomic hybrid clones have been compared for the ability to cooperate with the ras oncogene in transformation assays. From these experiments, it has become clear that the amino acid alanine at position 135, in either the genomic clone or the cDNA clone, failed to produce a p53 protein that cooperated with the ras oncogene and transformed cells. Replacing alanine with valine at this position in either the genomic or the cDNA clone activated for transformation in this assay. Using restriction enzyme polymorphisms in the p53 gene, it was shown that normal mouse DNA encodes alanine at position 135 in the p53 protein. Thus, mutation is required to activate the p53 protein for cooperation with the ras oncogene. After cotransfection with the activated ras gene, the genomic p53 DNA clone always produced more transformed cell foci (1.7-fold) than similar cDNA clones and these foci were more readily cloned (3.6-fold) into permanent cell lines. A series of deletion mutants of the genomic p53 clone were employed to show that the presence of intron 4 in the p53 gene was sufficient to provide much enhanced clonability of transformed foci from culture dishes. The presence of introns in the p53 gene constructions also resulted in elevated levels of p53 protein in the p53-plus-ras-transformed cell lines. Thus, qualitative changes in the p53 protein are required to activate p53 for transformation with the oncogene ras. Quantitative improvements of transformation frequencies are associated with the higher expression levels of altered p53 protein that are provided by having one of the p53 introns in the transforming plasmid.
Estimating Software Cost with Security Risk Potential

Software houses are now keen to provide secure software as requested by customers’ desire with respect to security and quality of their products especially related to the software costing estimation in the software development and implementation environment. Therefore, there is a need to identify the potential security risks while estimating the application cost. In this paper, we provide a list of potential security risks throughout the system development life cycle (SDLC). This list provides useful insights for software developers and practitioners in identifying security risks so that it can be encountered as security cost in the application.
Effects of Word Frequency on the A

This study investigates whether the acoustic durations of derivational affixes in Dutch are affected by the frequency of the word they occur in. In a word naming experiment, subjects were presented with a large number of words containing one of the affixes ge-, ver-, ont, or -lijk. Their responses were recorded on DAT tapes, and the durations of the affixes were measured using Automatic Speech Recognition technology. To investigate whether frequency also affected durations when speech rate was high, the presentation rate of the stimuli was varied. The results show that a higher frequency of the word as a whole led to shorter acoustic realizations for all affixes. Furthermore, affixes became shorter as the presentation rate of the stimuli increased. There was no interaction between word frequency and presentation rate, suggesting that the frequency effect also applies in situations in which the speed of articulation is very high.
Pilot trial of dialectical behavior therapy‐enhanced habit reversal for trichotillomania

Background: Not all hair pullers improve acutely with cognitive–behavioral treatment (CBT) and few maintain their gains over time. Methods: We conducted an open clinical trial of a new treatment that addresses affectively triggered pulling and emphasizes relapse prevention in addition to standard CBT approaches. Ten female participants satisfying DSM‐IV criteria for trichotillomania (TTM) at two study sites received Dialectical Behavior Therapy (DBT)‐enhanced CBT consisting of 11 weekly sessions and 4 maintenance sessions over the following 3 months. Independent assessors rated hair pulling impairment and global improvement at several study time points. Participants completed self‐report measures of hair pulling severity and emotion regulation. Results: Significant improvement in hair pulling severity and emotion regulation, as well as hair pulling impairment and anxiety and depressive symptoms, occurred during acute treatment and were maintained during the subsequent 3 months. Significant correlations were reported between changes in emotion regulation and hair pulling severity during both the acute treatment and maintenance phases. Conclusions: This study offers preliminary evidence for the efficacy of DBT‐enhanced CBT for TTM and suggests the importance of addressing emotion regulation during TTM treatment.

Current status of lectin-based cancer diagnosis and therapy

Lectins are carbohydrate recognizing proteins originating from diverse origins in nature, including animals, plants, viruses, bacteria and fungus. Due to their exceptional glycan recognition property, they have found many applications in analytical chemistry, biotechnology and surface chemistry. This manuscript explores the current use of lectins for cancer diagnosis and therapy. Moreover, novel drug delivery strategies aiming at improving lectin’s stability, reducing their undesired toxicity and controlling their non-specific binding interactions are discussed. We also explore the nanotechnology application of lectins for cancer targeting and imaging. Although many investigations are being conducted in the field of lectinology, there is still a limited clinical translation of the major findings reported due to lectins stability and toxicity concerns. Therefore, new investigations of safe and effective drug delivery system strategies for lectins are warranted in order to take full advantage of these proteins.
Brief exposure to NaCl during early postnatal development enhances adult intake of sweet and salty compounds

Taste acceptance involves both innate and acquired components. We observed an increased acceptance of salty and sweet solutions in adult rats whose tongues had been exposed to an NaCl-enriched milk formula during one day of early postnatal development. This behavioral effect was associated with changes in the norepinephrine system of the basolateral amygdala. No other changes in behavior, food intake, body weight, blood or metabolic parameters of the NaCl-exposed adult rats were identified. The data suggest a causal relationship between NaCl taste exposure, low content of amygdala norepinephrine cells and enhanced intake of sweet and salty compounds by adult rats. They also raise the question of the extent to which similar phenomena may occur during early human infant feeding.
Analysis of Lynch Syndrome Mismatch Repair Genes in Women with Endometrial Cancer

Objective: Endometrial cancer is the second most frequent neoplasm in women with Lynch syndrome (LS). We sought to assess whether analyzing women with endometrial cancer would identify families with LS not identified with current clinical criteria. Methods: We included women diagnosed with endometrial cancer younger than 50 years and also older if they had a family cancer history associated with LS. In blood samples obtained, we analyzed mutations in mismatch repair (MMR) genes, as well as protein expression by immunohistochemistry and microsatellite instability (MSI) in tumour tissue. Results: A total of 103 patients were enrolled. We detected 14 pathogenic mutations and 4 genetic variants of unknown clinical significance in MMR genes. We found MSI in 41.66% of the women with a pathogenic mutation. In this group, 76.92% showed loss of at least one MMR protein. Women with mutations were younger at diagnosis, but all of them had a family history compatible with LS. Conclusions: Analysis of the MMR genes, in particular MSH6, seems to be appropriate in women with endometrial cancer and a family history of tumours associated with LS.
