ResAll: Energy efficiency maximization for wireless energy harvesting sensor networks

Energy harvesting is a promising solution to prolong the lifetime of energy-constrained wireless sensor networks. In particular, scavenging energy from ambient radio frequency (RF) signals has drawn a lot of attention recently. In this paper, we apply simultaneous wireless information and power transfer (SWIPT) to a clustered sensor network such that a cluster head node harvests the wireless energy of received RF signals from its cluster members and then employs the harvested energy to compensate the energy consumed by data aggregating and forwarding. In such a network, how to achieve high energy efficiency through trading off between energy harvesting and information decoding is a critical issue. To this end, we formulate the rate and power resource allocation problem in a clustered WSN with SWIPT as a non-convex constrained energy efficiency maximization problem. By exploiting fractional programming and dual decomposition, we further propose a cross-layer resource allocation (ResAll) algorithm consisting of subalgorithms of rate control, power allocation and power splitting to solve the problem efficiently and optimally. Our simulation results reveal that the proposed ResAll algorithm converges within a small number of iterations, and achieves optimal system energy efficiency by balancing energy efficiency, data rate, transmit power and power splitting ratio.
A Rare Cause for Cervical Pain: Eagle's Syndrome

Patients with pharyngodynia and neck pain symptoms can lead to an extensive differential diagnosis. Eagle's syndrome must be taken in account. Eagle defined "stylalgia" as an autonomous entity related to abnormal length of the styloid process or to mineralization of the stylohyoid ligament complex. The stylohyoid complex derives from Reichert's cartilage of the second branchial arch. The styloyd process is an elongated conical projection of the temporal bone that lies anteriorly to the mastoid process. The incidence of Eagle's syndrome varies among population. Usually asymptomatic, it occurs in adult patients. It is characterized by pharyngodynia localized in the tonsillar fossa and sometimes accompanied by disphagia, odynophagia, foreign body sensation, and temporary voice changes. In some cases, the stylohyoid apparatus compresses the internal and/or the external carotid arteries and their perivascular sympathetic fibers, resulting in a persistent pain irradiating in the carotid territory. The pathogenesis of the syndrome is still under discussion.
The State of IT Governance in Organizations from the Public Sector in a Developing Country

Today in many organizations in the public sector, the use of IT has become crucial in sustaining and extending the organizations' strategies and objectives. This pervasive use of technology has caused a critical dependency on IT that calls for specific focus on the IT Governance. This paper discusses the current state of IT Governance practices in five public sector organizations from a developing country, like is Tanzania. The results of this research approach are looking into the IT Governance mechanisms in place in terms of structures, processes and relational mechanisms. Moreover the paper includes a discussion on the problems and consequences inherent to inhibitors of effective IT Governance for a further improvement of the public service delivery in this environment.

The objective of the present investigation is to elucidate hepatoprotective activity of Methanolic Fruit extract of Feronia elephantum in paracetamol induced liver damage in Wistar rats. Liver damage was produced by paracetamol (2gm/kg,p.o.) in 1% CMC. The Plant extract (200mg/kg, p.o.) was administered every 24 hrs for seven days, while standard group received N-acetyl l-cystine. At the end of the study the marker enzymes in serum were analysed.The methanolic extract showed significant hepatoprotective activity and efficacy of extract was almost comparable to that of N-acetyl l-cystine.
Zoledronic acid for the treatment of osteoporosis in patients with beta-thalassemia: results from a single-center, randomized, placebo-controlled trial.

BACKGROUND AND OBJECTIVES
The aim of this study was to evaluate the effect of zoledronic acid (ZA) on thalassemia-induced osteoporosis.


DESIGN AND METHODS
We studied 66 thalassemia patients with osteoporosis, who were randomized to receive 4 mg ZA iv, every 6 months (23 patients; group A) or every 3 months (21 patients; group B), or to receive placebo every 3 months (22 patients; group C), for a period of 1 year. Bone mineral density (BMD) of the lumbar spine, femoral neck and wrist was determined before and 12 months after treatment. Pain scores and markers of bone resorption [C-telopeptide of collagen type-I (CTX), 5b-isoform of TRAP], bone formation [bone-alkaline phosphatase (bALP), osteocalcin (OC), C-telopeptide of procollagen type-I (CICP)], and osteoclast stimulators [sRANKL, osteoprotegerin (OPG), osteopontin] were also measured at baseline and before each treatment administration.


RESULTS
The values of CTX, bALP, CICP, sRANKL, and OPG were higher in the all patients than in the controls. Patients in group A showed no differences in BMD of all sites at 12 months, while they had reductions in bone pain, bALP, OC and OPG. Conversely patients in group B had a significant increase in their lumbar spine BMD, which was accompanied by dramatic reductions in bone pain, CTX, bALP, CICP, and OC. Patients in group C showed no alteration in BMD of any studied site or in bone pain, while they had an aggravation in bone resorption.


INTERPRETATION AND CONCLUSIONS
ZA, at a dose of 4 mg, iv, every 3 months is an effective treatment for increasing BMD and reducing bone resorption in thalassemia-induced osteoporosis.
Detection of Argan Oil Adulteration Using Quantitative Campesterol GC-Analysis

Detection of edible oil adulteration is of utmost important to ensure product quality and customer protection. Campesterol, a sterol found in seed oils, represents less than 0.4% of argan oil total sterol content. Quantitative analysis of campesterol by gas chromatography of argan oil and of a mixture of argan oil and readily commercially available vegetable oils, consecutively with sterol separation, was carried out. Our study clearly demonstrated that determination of the campesterol level in argan oil (or oil presented as argan oil) can be proposed as the major analysis method to assess unambiguously argan oil purity up to 98%.
Diamond-alpha Grüss type inequalities on time scales

Refinement of the use of non-human primates in scientific research. Part II: housing, husbandry and acquisition

In order to safeguard the welfare of laboratory-housed non-human primates, refinement techniques should be applied to every aspect of the life of animals used in the laboratory, from birth to death, with the aim of both minimising harm and maximising well-being. In this second part of a three-part review we summarise published information on housing and husbandry practices, and describe ways to minimise contingent inhumanity associated with the use of primates in laboratories and their breeding and supply (where inhumanity is defined as the infliction of distress). We also discuss methods by which the welfare of these animals can be maximised on a day-to-day basis. The principles of enrichment, aspects of the housing environment, social and physical enrichment and acquisition are discussed. Refinement of the influence of humans and experimental procedures are discussed in Parts I and III of this review, respectively.
A versatile microreactor platform featuring a chemical-resistant microvalve array for addressable multiplex syntheses and assays

A versatile microreactor platform featuring a novel chemical-resistant microvalve array has been developed using combined silicon/polymer micromachining and a special polymer membrane transfer process. The basic valve unit in the array has a typical ‘transistor’ structure and a PDMS/parylene double-layer valve membrane. A robust multiplexing algorithm is also proposed for individual addressing of a large array using a minimal number of signal inputs. The in-channel microvalve is leakproof upon pneumatic actuation. In open status it introduces small impedance to the fluidic flow, and allows a significantly larger dynamic range of flow rates (∼ml min−1) compared with most of the microvalves reported. Equivalent electronic circuits were established by modeling the microvalves as PMOS transistors and the fluidic channels as simple resistors to provide theoretical prediction of the device fluidic behavior. The presented microvalve/reactor array showed excellent chemical compatibility in the tests with several typical aggressive chemicals including those seriously degrading PDMS-based microfluidic devices. Combined with the multiplexing strategy, this versatile array platform can find a variety of lab-on-a-chip applications such as addressable multiplex biochemical synthesis/assays, and is particularly suitable for those requiring tough chemicals, large flow rates and/or high-throughput parallel processing. As an example, the device performance was examined through the addressed synthesis of 30-mer DNA oligonucleotides followed by sequence validation using on-chip hybridization. The results showed leakage-free valve array addressing and proper synthesis in target reactors, as well as uniform flow distribution and excellent regional reaction selectivity.

Clinical Outcome and Fusion Rates after the First 30 Extreme Lateral Interbody Fusions

INTRODUCTION
The lateral transpsoas approach for lumbar interbody fusion (XLIF) is gaining popularity. Studies examining a surgeon's early experience are rare. We aim to report treatment, complication, clinical, and radiographic outcomes in an early series of patients.


METHODS
Prospective data from the first thirty patients treated with XLIF by a single surgeon was reviewed. Outcome measures included pain, disability, and quality of life assessment. Radiographic assessment of fusion was performed by computed tomography.


RESULTS
Average follow-up was 11.5 months, operative time was 60 minutes per level and blood loss was 50 mL. Complications were observed: clinical subsidence, cage breakage upon insertion, new postoperative motor deficit and bowel injury. Approach side-effects were radiographic subsidence and anterior thigh sensory changes. Two patients required reoperation; microforaminotomy and pedicle screw fixation respectively. VAS back and leg pain decreased 63% and 56%, respectively. ODI improved 41.2% with 51.3% and 8.1% improvements in PCS and MCS. Complete fusion (last follow-up) was observed in 85%.


CONCLUSION
The XLIF approach provides superior treatment, clinical outcomes and fusion rates compared to conventional surgical approaches with lowered complication rates. Mentor supervision for early cases and strict adherence to the surgical technique including neuromonitoring is essential.

A Forward Genetic Screen in Zebrafish Identifies the G-Protein-Coupled Receptor CaSR as a Modulator of Sensorimotor Decision Making

Animals continuously integrate sensory information and select contextually appropriate responses. Here, we show that zebrafish larvae select a behavioral response to acoustic stimuli from a pre-existing choice repertoire in a context-dependent manner. We demonstrate that this sensorimotor choice is modulated by stimulus quality and history, as well as by neuromodulatory systems-all hallmarks of more complex decision making. Moreover, from a genetic screen coupled with whole-genome sequencing, we identified eight mutants with deficits in this sensorimotor choice, including mutants of the vertebrate-specific G-protein-coupled extracellular calcium-sensing receptor (CaSR), whose function in the nervous system is not well understood. We demonstrate that CaSR promotes sensorimotor decision making acutely through Gαi/o and Gαq/11 signaling, modulated by clathrin-mediated endocytosis. Combined, our results identify the first set of genes critical for behavioral choice modulation in a vertebrate and reveal an unexpected critical role for CaSR in sensorimotor decision making.
Fatigue and sleep disturbance following traumatic brain injury--their nature, causes, and potential treatments.

BACKGROUND
Although fatigue and sleep disturbance are commonly reported following traumatic brain injury (TBI), understanding of their nature and treatment remains limited.


OBJECTIVES
This article reviews a series of investigations of the nature and causes of fatigue and sleep disturbance following TBI.


METHODS
A large cohort of community-based patients with TBI, recruited from a TBI rehabilitation program, completed measures of subjective fatigue and sleep disturbances, as well as attentional measures. A subgroup of participants completed polysomnography and assessment of dim light melatonin onset.


RESULTS
Fatigue and sleep disturbance are common. Both are associated with anxiety, depression, and pain. However, fatigue is also associated with slowed information processing and the need for increased effort in performing tasks. Sleep disturbances contribute to fatigue. Objective sleep studies show reduced sleep efficiency, increased sleep onset latency, and increased time awake after sleep onset. Depression and pain exacerbate but cannot entirely account for these problems. There is increased slow-wave sleep. Individuals with TBI show lower levels of evening melatonin production, associated with less rapid-eye movement sleep.


CONCLUSIONS
These findings suggest potential treatments including cognitive behavior therapy supporting lifestyle modifications, pharmacologic treatments with modafinil and melatonin, and light therapy to enhance alertness, vigilance, and mood. Controlled trials of these interventions are needed.
A framework for business model driven development

Typically, large companies in an effort to increase efficiency specify business processes using workflow languages, while software designers specify the systems that implement these processes with the use of languages like UML. This separation of domain expertise allows for software engineers from each individual area to work more efficiently using domain specific languages and tools. However, models in these two domains evolve independently and inconsistencies may occur when two models become unsynchronized due to constant revision or evolution of processes and design artifacts. In this paper, we present a set of transformations to automatically generate a specific set of UML artifacts from the business process specifications. In particular, we examine and investigate a preliminary framework for the necessary annotations that need be applied to a business process model so that the generation of UML use cases, activity diagrams, collaboration diagrams and deployment diagrams could be feasible. The objective of this work is to be able to generate rich platform independent UML models that can be used for automating the generation of design artifacts and source code by using a model driven architecture approach. By doing so, we aim to decrease software design time, reduce maintenance costs and better support system evolution
A multicenter retrospective cohort study of practice patterns and clinical outcome on radiotherapy for hepatocellular carcinoma in Korea.

AIM
To determine the national practice processes of care and outcomes of radiotherapy for hepatocellular carcinoma (HCC) in Korea.


PATIENTS AND METHODS
A national survey of 53 institutions nationwide was conducted by requesting data on their experience of radiotherapy for HCC. Among them, 10 institutions were selected for performing more detailed analysis, based on the radiotherapy experience of at least five HCC patients between 2004 and 2005.


RESULTS
This study covered the treatment of 398 HCC patients for 2 years. Most patients (78%) were in stage III or IV. Radiotherapy was chosen after the failure of other treatments, most frequently transarterial chemoembolization. Radiotherapy was performed predominantly using the three-dimensional conformal technique (3D-CRT, 81.9%) mostly with a total dose of >/=45 Gy. In 9.3% of the patients, radiotherapy was performed using radiosurgery. In a biologically effective dose (BED) with 10 Gy of alpha/beta, 4.2-124.3 Gy(10) was delivered. The median survival time was 12 months, and the 2-year overall survival rate was 27.9%. A tumour size <5 cm, a negative lymph node and BED >53.1 Gy(10) were shown by multivariate analysis to be significant factors for a better prognosis. In a subset analysis for the 326 patients treated with 3D-CRT, better liver function with Child-Pugh class A was shown to be an additional factor for a better prognosis.


CONCLUSIONS
Radiotherapy has been used to treat advanced HCC in various modes, but mostly as a salvage treatment. Although this study was retrospective, it indicates that radiotherapy is a quite effective modality for HCC patients.
A proposed Food Safety Management Framework for Catering Services

Safe food is essential for life and food safety has become a watchword in most catering organizations. Despite the widely accepted gains emerging from adopting food safety management system models worldwide, food catering sectors seem not to have made benefit towards deploying such systems in improving their food safety and hygiene practices. The problem lies in the nature and complicated requirements and norms of the current frameworks and associated roadmaps towards effective implementation of food safety management initiatives. The present paper proposes a food safety management framework for food services and catering sector based on integrating several internationally recognized food safety and food quality management systems; the international standard ISO 22000:2005 requirements for any organization in the food chain , Hazard Analysis and Critical Control Points (HACCP), Codex Alimentarius Commission, together with the quality management system ISO 9000:2008 series. It is expected that the proposed framework overcomes limitations inherent in other food safety management concepts and approaches. The proposed framework is distinguished by its agility among constituents, and can be used to self-assess organization's food safety management initiatives and efforts to assess their progress over time. The proposed framework is appropriate, feasible for implementation, and was tested in an educational organization; it provides information and guidance for caterers, to help them provide healthier and safer food for their customers. Key-Words: -Food safety and quality management systems, food regulations, HACCP, 22000:2005 standard, International standards, guidelines and recommendations, catering services, product development.
Comparison of edge computing implementations: Fog computing, cloudlet and mobile edge computing

When it comes to storage and computation of large scales of data, Cloud Computing has acted as the de-facto solution over the past decade. However, with the massive growth in intelligent and mobile devices coupled with technologies like Internet of Things (IoT), V2X Communications, Augmented Reality (AR), the focus has shifted towards gaining real-time responses along with support for context-awareness and mobility. Due to the delays induced on the Wide Area Network (WAN) and location agnostic provisioning of resources on the cloud, there is a need to bring the features of the cloud closer to the consumer devices. This led to the birth of the Edge Computing paradigm which aims to provide context aware storage and distributed Computing at the edge of the networks. In this paper, we discuss the three different implementations of Edge Computing namely Fog Computing, Cloudlet and Mobile Edge Computing in detail and compare their features. We define a set of parameters based on which one of these implementations can be chosen optimally given a particular use-case or application and present a decision tree for the selection of the optimal implementation.
Review and the state of the art: Sol-gel and melt quenched bioactive glasses for tissue engineering.

Biomaterial development is currently the most active research area in the field of biomedical engineering. The bioglasses possess immense potential for being the ideal biomaterials due to their high adaptiveness to the biological environment as well as tunable properties. Bioglasses like 45S5 has shown great clinical success over the past 10 years. The bioglasses like 45S5 were prepared using melt-quenching techniques but recently porous bioactive glasses have been derived through sol-gel process. The synthesis route exhibits marked effect on the specific surface area, as well as degradability of the material. This article is an attempt to provide state of the art of the sol-gel and melt quenched bioactive bioglasses for tissue regeneration. Fabrication routes for bioglasses suitable for bone tissue engineering are highlighted and the effect of these fabrication techniques on the porosity, pore-volume, mechanical properties, cytocompatibilty and especially apatite layer formation on the surface of bioglasses is analyzed in detail. Drug delivery capability of bioglasses is addressed shortly along with the bioactivity of mesoporous glasses. © 2015 Wiley Periodicals, Inc.
