Privacy-Preserving Data Outsourcing in Cloud Computing

In cloud computing, data owners are motivated to outsource their complex data management systems from local sites to the commercial public cloud for great flexibility and economic savings. But for protecting data privacy, sensitive data has to be encrypted before outsourcing, which obsoletes traditional data utilization based on plaintext keyword search. Thus, enabling an encrypted cloud data search service is of paramount importance. Considering the large number of data users and documents in the cloud, it is necessary to allow multiple keywords in the search request and return documents in the order of their relevance to these keywords. Related works on searchable encryption focus on single keyword search or Boolean keyword search, and rarely sort the search results. In this paper, for the first time, we define and solve the challenging problem of privacy preserving multi-keyword ranked search over encrypted cloud data (MRSE). We establish a set of strict privacy requirements for such a secure cloud data utilization system. Among various multikeyword semantics, we choose the efficient similarity measure of “coordinate matching”, We first propose a basic idea for the MRSE based on secure inner product computation, and then give two significantly improved MRSE schemes to achieve various stringent privacy requirements in two different threat models. Thorough analysis investigating privacy and efficiency guarantees of proposed schemes is given. Experiments on the real-world dataset further show proposed schemes indeed introduce low overhead on computation and communication.
Same Supply Chain, Different Models: Integrating Perspectives from Life Cycle Assessment and Supply Chain Management

Within industrial ecology, there is a substantial community focusing on life cycle assessment (LCA) and corresponding tools and methods. Within the field of supply chain management, an increasing community is converging around sustainable supply chains. These two communities study the same underlying systems, but bring different perspectives to bear. We review seven issues that arise at this intersection of LCA and supply chain management, with the aim of illustrating how both communities can enrich each other by closer interaction. We conclude with some suggestions for how the two communities can further collaborate.
Current opinion on optimal treatment for colorectal cancer

The medical treatment of colorectal cancer (CRC) has evolved greatly in the last 10 years, involving complex combined chemotherapy protocols and, in more recent times, new biologic agents. Advances in adjuvant therapy have been limited to the addition of oxaliplatin and the substitution of oral fluoropyrimidine (e.g., capecitabine) for intravenous 5-fluorouracil with no evidence for improved outcome with biological agents. Clinical benefit from the use of the targeted monoclonal antibodies, bevacizumab, cetuximab and panitumumab, in the treatment of metastatic CRC is now well established, but the optimal timing of their use requires careful consideration to derive the maximal benefit. Evidence to date suggests potentially distinct roles for bevacizumab and EGF receptor-targeted biological agents (cetuximab and panitumumab) in the treatment of metastatic CRC. This article reviews the evidence in support of modern treatments for CRC and the decision-making behind the treatment choices, their benefits and toxicities.
Safety Profiles and Lesion Size of Different Radiofrequency Ablation Technologies: A Comparison of Large Tip, Open and Closed Irrigation Catheters

Safety Versus Lesion Size of Ablation Catheters. Introduction: Different technologies have been developed for radiofrequency ablation (RFA), which include increasing electrode (tip) size and cooling the tip through irrigation either internally (closed‐loop) with D5W or externally (open‐loop) with saline. Although these catheters are widely used clinically, the propensity for adverse events and the lesion profiles of each of these catheter technologies have not been directly compared under a wide range of controlled conditions.
Pathological airway remodelling in inflammation

Introduction: Airway remodelling refers to a wide pattern of patophysiological mechanisms involving smooth muscle cell hyperplasia, increase of activated fibroblasts and myofibroblasts with deposition of extracellular matrix. In asthma, it includes alterations of the epithelial cell layer with goblet cell hyperplasia, thickening of basement membranes, peri‐bronchial and peri‐broncheolar fibrosis. Moreover, airway remodelling occurs not only in asthma but also in several pulmonary disorders such as chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and systemic sclerosis. Asthma treatment with inhaled corticosteroids does not fully prevent airway remodelling and thus have restricted influence on the natural course of the disease.
Automatically Identifying Reusable OO Legacy Code

Much object oriented code has been written without reuse in mind, making identification of useful components difficult. The Patricia (Program Analysis Tool for Reuse) system automatically identifies these components through understanding comments and identifiers. To understand a program, Patricia uses a unique heuristic approach, deriving information from the linguistic aspects of comments and identifiers and from other nonlinguistic aspects of OO code, such as a class hierarchy. In developing the Patricia system, we had to overcome the problems of syntactically parsing natural language comments and syntactically analyzing identifiers-all prior to a semantic understanding of the comments and identifiers. Another challenge was the semantic understanding phase, when the organization of the knowledge base and an inferencing scheme were developed.
Evaluating the internal consistency of ISO/IEC TR 15504 process capability measures

A software process assessment based on the emerging International Standard ISO/IEC 15504 (Software Process Assessment) can be considered a subjective measurement procedure since assessors assign ratings to measures (i.e. PA: process attributes) to measure the capability of processes. Since measurement always includes some amount of random measurement error, evaluating the reliability of empirical measurement in ISO/IEC 15504–based process assessment is crucial to give confidence to the assessment results. This study estimated the internal consistency (reliability) of process attributes by utilizing Cronbach's alpha. For this purpose, we analyzed 364 process instances from 29 assessments on the basis of ISO/IEC 15504 in Korea during February 1999 and December 2001. Our result shows that Cronbach's alpha has a high value of 0.88 for use in practice. This is the same value as obtained in the data from the Phase 2 SPICE Trials (between September 1996 and June 1998), where SPICE denotes Software Process Improvement and Capability dEtermination. In addition, this study explored whether the change of the current four-category PA rating scale increases the internal consistency. Our findings indicate that the current four-category rating scale gives higher internal consistency of process capability measures than a two- or a three-category rating scale.

Assessment of contemporary stent deployment using intravascular ultrasound

Four second‐ and third‐generation coronary stents were evaluated using QCA and intravascular ultrasound for adequacy of stent expansion, the influence of disease burden on adequacy of deployment, and postdeployment structural effects on the artery. Despite satisfactory stent deployment rates on angiography of 92 %, adequate stent deployment by IVUS ranged from 38% to 55%. There was no significant difference in deployment success across the four stent types. Lesions with significant plaque burden were associated with a lower rate of deployment success (P = 0.04). Twenty‐one edge dissections were demonstrated by IVUS; only six were detected by angiography. Observations made on first‐generation stents regarding adequacy of deployment still hold true for newer‐generation stents. Significant plaque burden is an independent negative predictor of stent deployment success. The presence of IVUS‐detected edge dissections indicates that the extent of injury during PCI extends beyond the physical length of the stent.

Using a distributed knowledge base to coordinate autonomous mobile systems

The autonomy of mobile systems increases constantly. That means that the flexibility of their task execution, their capabilities to handle local conflicts and the usage of their local knowledge increase. The paper shows that because of this autonomy coordination in a factory must be reconsidered and that global coordination is still able to improve the efficiency and the safety of autonomous mobile systems. It suggests a knowledge structure for coordination containing global information which is called section knowledge. This section knowledge helps the mobile systems to coordinate themselves. Furthermore, some agents, using the section knowledge, are introduced which can advise the mobile systems. The section knowledge is stored in the distributed knowledge base, whose features of preventing the section knowledge of becoming a bottleneck are explained.
DETERMINATION OF PARAMETERS OF EXCITED STATES OF DNA and RNA BASES BY LASER UV PHOTOLYSIS

Abstract— The mechanism of photodecomposition of nucleic acid bases in a neutral aqueous solution upon two‐step excitation of high‐lying electronic states by a powerful laser UV radiation is discussed. Experimental dependences of photodecomposition efficiency versus UV radiation intensity are measured both under picosecond and nanosecond laser UV irradiations. By comparison of experimental dependences with a theoretical model, we obtain some characteristics of excited states, such as lifetime t1 of the first electronic excited state S1 intersystem crossing yield φ, photosensitivity from an intermediate excited state and others for all five nucleic acid bases.
Event Matching from Significantly Different Views using Motion Barcodes

We introduce a method to determine if two videos are of the same event even when they are taken from significantly different viewing directions. Based on this, a video can be retrieved from a database of events, and video collections can be clustered into sets of videos each viewing the same event. Our method works well even in cases where the videos are so different that appearance based methods (e.g. SIFT) are not sufficient. This viewpoint invariance is based on a new pixelbased feature, “motion barcode”, which records the existence/non-existence of motion as a function of time. While appearance, motion magnitude, and motion direction can vary between viewpoints, the existence of motion is viewpoint invariant. Based on the motion barcode, a similarity measure is developed for videos from very different viewpoints. This measure is robust to occlusions common under different viewpoints and can be computed efficiently We show the utility of motion barcodes using challenging sequences from stationary and hand held cameras.
Exclusive breastfeeding reduces asthma in a group of children from the Caguas municipality of Puerto Rico.

UNLABELLED Breast-feeding is the preferred method of infant nutrition. Its role in preventing childhood asthma is controversial. OBJECTIVE Determine whether breastfeeding protects against the development of bronchial asthma in children. METHODS A survey was answered by parents of children less than 18 years of age attending a Pediatric clinic at Cidra, Puerto Rico from July to December 2008. RESULTS A group of 175 mothers were included in the study. The mean age was 28 years (range 14-50). The mean age of the children was 5 years. There was family history of asthma in 64% of the families. The prevalence of asthma in these children was 50%. Sixty-six percent of the mother's breastfed but only 27% did it exclusively. Children who were exclusively breastfed had a lower prevalence of asthma and milk protein allergy. CONCLUSIONS This study correlates with literature reports linking exclusive breastfeeding to a reduction in asthma and other allergic diseases.
Exploiting RF signal attenuation for passive indoor location tracking of an object

This paper presents a conceptual design for tracking the location of a moving object within an indoor array of wireless transceivers passively, without the need for an electronic device or tag attached to the object. The conventional problem of signal attenuation due to object blocking, or shadowing prevalent in a typical wireless communication system is exploited to track an object. This is based on the principle of signal attenuation resulting from the object blocking the line-of-sight (LOS) link in a transceiver set. In particular, Wi-Fi transceivers operating at a frequency of 2.4 GHz (IEEE 802.11g standard) have been investigated. The estimated location is approximated using the measured received signal strength (RSS) and the relative distances between the transmitters and a receiver. Experimental results within a 3 m × 5 m area show that it is possible to track a human being using the proposed configuration.
Percutaneous endoscopic gastrostomy (PEG) in patients with ALS and bulbar dysfunction

OBJECTIVE: To compare characteristics of ALS patients with and without percutaneous endoscopic gastrostomy (PEG). METHODS: Using the ALS Patient Care Database, data from patients with and without PEG with ALS Functional Rating Scale‐bulbar subscale (ALSFRSb) scores ≤5 were analyzed; follow‐up data were also collected. RESULTS: PEG use was markedly increased with declining ALSFRSb scores. Demographics did not differ, but ALSFRS composite scores and bulbar and arm subscale scores were lower (P<0.0001). PEG patients used significantly more assistive devices, multidisciplinary care, home care nurses and aides, had more frequent physician and emergency department visits and hospital admissions (P<0.0001), and had lower health status based on the mini‐SIP scale (P=0.0047). PEG use varied greatly between ALS centers. In the follow‐up study, positive impact of PEG was noted in 79 % of PEG patients but in only 37.5% of patients who received PEG later, based on a small number of patients. PEG use showed no survival benefit. CONCLUSION: Patients did not receive PEG until bulbar function was severely reduced and overall ALS had markedly progressed. PEG may have been performed too late to demonstrate survival benefits. Aggressive proactive nutritional management appears essential in patients with ALS. To determine whether PEG provides benefits, it must be performed at earlier stages of the disease and prospectively studied.
A Cluster Head Aggregation Scheme for Early Elimination of Global Redundancy In a Cluster-based Model of Integrated RFID and Wireless Sensor Networks

RFID and wireless sensor networks (WSNs) are emerging technologies to complement each other. However, there are several problems to be solved in order to get proliferation of their use. One of them is to eliminate the redundant data generated by nodes due to the overlapped reading range. Elimination of the redundant data is of importance because it saves the power consumption by avoiding the unnecessary redundant data transmission in the integrated RFID and WSNs. In this paper, we propose a cluster head aggregation scheme called 2PA (2-Phase Aggregation) for reducing redundant data transmission in a cluster-based model of integrated RFID and WSNs.2PA can contribute to reduction of energy consumption because redundant data can be detected in advance before it traverses cluster heads(CHs) along the routing path. This implies that introducing 2PA can obtain the additional benefit of avoiding the unnecessary computation for duplicate detection of redundant readings for a RFID tag at each CH.
Adverse Selection Model in E-Commerce

Adverse selection means the selection by the consumer when faced with the circumstance of asymmetric information. Adverse selection model was suggested by the American economist George Akerlof (1970), who is one of Nobel Economics Prize laureates in 2001. With this model, Akerlof indeed explains many economic institutions and many important aspects of uncertainty. But the model studies the traditional markets (tangible markets), how about the e-commerce that are based on the Internet? Based on Akerlof model, this paper builds up the adverse selection model in the ecommerce markets, and probes into resolving approaches about the adverse selection in e-commerce.

Pattern of calretinin immunoreactivity in the main olfactory system and the vomeronasal system of the tree shrew, Tupaia belangeri

The distribution of the calcium‐binding protein calretinin was studied in peripheral and central parts of the main olfactory system (MOS) and the vomeronasal system ( VNS ) of adult tree shrew Tupaia belangeri. The calretinin immunoreaction was carried out with a peroxidase‐coupled polyclonal antibody. In the VNS, complete labeling of all receptor cells and vomeronasal nerve fibers was observed, whereas only a subset of the somata and dendrites of receptor cells and of the olfactory nerve fibers of the MOS was immunoreactive. From the immunoreactive dendritic clubs of vomeronasal receptor cells, calretinin‐labeled structures, presumably clumps of microvilli, arose that terminated within immunopositive portions of the mucus. In the main olfactory bulb, the neuropil of some of the glomeruli was immunoreactive. All periglomerular and many mitral cells were labeled. The external plexiform layer was subdivided into a faintly immunoreactive superficial half and a strongly immunoreactive deep half. Immunoreactive basal dendrites of mitral cells could be followed into either the deep half or the superficial half. In the laminated internal granular layer, a subset of immunopositive granule cells extended dendrites into the external plexiform layer. Mitral cells and granule cells with dendrites ascending to different levels of the external plexiform layer may represent functional subclasses. In the accessory olfactory bulb, all vomeronasal nerve fibers, glomeruli, and mitral/tufted cells were labeled, whereas immunoreactive periglomerular cells and internal granule cells were only scattered. In Tupaia, calretinin immunoreactivity is a more general property of the primary projecting neurons of the VNS than of the MOS and possibly indicates the involvement of calretinin in the perception of certain of the olfactory qualities.

Th17 cells in rheumatoid arthritis and systemic lupus erythematosus

Recent work has implicated a novel Th effector cell subset, the Th17 cell subset, in the development of both rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) because of the ability of Th17 cells to produce cytokines like IL‐17 and IL‐21 that can drive both inflammatory and humoral responses. In this review, we will discuss recent studies that have begun elucidating the factors that regulate the development of Th17 cells and provide a brief overview of the role of Th17 cells in RA and SLE.
Socio‐economic benefits from protected areas in southeastern Australia

International case studies of protected area performance increasingly report that conservation and socio‐economic outcomes are interdependent. Effective conservation requires support and cooperation from local governments and communities, which in turn requires that protected areas contribute to the economic well‐being of the communities in which they are sited. Despite increasing recognition of their importance, robust studies that document the socio‐economic impacts of protected areas are rare, especially in the developed world context. We proposed 3 potential pathways through which protected areas might benefit local communities in the developed world: the improved local housing value, local business stimulus, and increased local funding pathways. We examined these pathways by undertaking a statistical longitudinal analysis of 110 regional and rural communities covering an area of approximately 600,000 km2 in southeastern Australia. We compared trends in 10 socio‐economic indicators describing employment, income, housing, business development and local government revenue from 2000 to 2010. New protected areas acquisitions led to an increased number of new dwelling approvals and associated developer contributions, increased local business numbers, and increased local government revenue from user‐pays services and grants. Longer‐term effects of established protected areas included increased local council revenue from a variety of sources. Our findings provide support for each of our 3 proposed benefit pathways and contribute new insights into the cycling of benefits from protected areas through the economy over time. The business and legislative models in our study are typical of those operating in many other developed countries; thus, the benefit pathways reported in our study are likely to be generalizable. By identifying and communicating socio‐economic benefits from terrestrial protected areas in a developed world context, our findings represent an important step in securing local support and ongoing high‐level protection for key components of the world's biodiversity.
Chemical communication among bacteria

Cell–cell communication in bacteria is accomplished through the exchange of chemical signal molecules called autoinducers. This process, called quorum sensing, allows bacteria to monitor their environment for the presence of other bacteria and to respond to fluctuations in the number and/or species present by altering particular behaviors. Most quorum-sensing systems are species- or group-specific, which presumably prevents confusion in mixed-species environments. However, some quorum-sensing circuits control behaviors that involve interactions among bacterial species. These quorum-sensing circuits can involve both intra- and interspecies communication mechanisms. Finally, anti-quorumsensing strategies are present in both bacteria and eukaryotes, and these are apparently designed to combat bacteria that rely on cell–cell communication for the successful adaptation to particular niches.
Isolation and identification of marine chitinolytic bacteria and their potential in antifungal biocontrol.

Chitinolytic marine bacterial strains (30) were isolated from the sea dumps at Bhavnagar, India. They were screened as chitinase producers on the basis of zone of clearance on chitin agar plates incorporated with calcofluor white M2R for the better resolution. Out of these, three strains namely, Pseudomonas sp. , Pantoea dispersa and Enterobacter amnigenus showed high chitinase production. They were also found to produce proteases and therefore have a good potential for use as antifungal biocontrol agents for the control of fungal plant pathogens. These strains could degrade and utilize the mycelia of Macrophomina phaseoliena (Tassi) Goidanich and Fusarium sp. In vitro, these strains could inhibit the growth of Fusarium sp. and M. phaseolina. The culture filtrate inhibiting hyphal elongation was observed microscopically.
