IPANM: Incentive Public Auditing Scheme for Non-Manager Groups in Clouds

Cloud storage services give users a great facility in data management such as data collection, storage and sharing, but also bring some potential security hazards. An utmost importance is how to ensure the integrity of data files stored in the cloud, particular for user groups without trusted managers. Existing literature focuses on integrity checking for groups with managers who have lots of permissions. To overcome the shortage of public auditing for non-manager user groups in clouds, we develop a novel framework IPANM that integrates <inline-formula><tex-math notation="LaTeX">$(t,n)$</tex-math><alternatives><mml:math><mml:mrow><mml:mo>(</mml:mo><mml:mi>t</mml:mi><mml:mo>,</mml:mo><mml:mi>n</mml:mi><mml:mo>)</mml:mo></mml:mrow></mml:math><inline-graphic xlink:href="zhou-ieq1-3004827.gif"/></alternatives></inline-formula> threshold technology, blinding technology, and incentive mechanism to realize an incentive privacy-preserving public auditing scheme. In IPANM, the data integrity is guaranteed by our <inline-formula><tex-math notation="LaTeX">$(t,n)$</tex-math><alternatives><mml:math><mml:mrow><mml:mo>(</mml:mo><mml:mi>t</mml:mi><mml:mo>,</mml:mo><mml:mi>n</mml:mi><mml:mo>)</mml:mo></mml:mrow></mml:math><inline-graphic xlink:href="zhou-ieq2-3004827.gif"/></alternatives></inline-formula> threshold signature based public auditing and the data privacy during public auditing is protected by the blinding technology. The generation of signatures can be accelerated by our blockchain-aided incentive mechanism that mobilizes the initiative of signers in the signature generation by rewarding the contributed signers. We formally prove the security of our IPANM and conduct numerical analysis and evaluation study to validate its high efficiency. The experimental results demonstrate that IPANM has lower overheads of storage, communication, and computation as compared to the state-of-the-art technique IAID-PDP and NPP.
An Integrated Bistatic 4TX/4RX Six-Port MIMO-Transceiver at 60 GHz in a 130-nm SiGe BiCMOS Technology for Radar Applications

In this paper, a scalable, fully digital adjustable, bistatic 60 GHz MIMO six-port transceiver is presented. The circuit features four independent transmitters and four six-port receivers on a single chip. The reference clock frequency of 15 GHz is buffered and multiplied up to 60 GHz. The reference clock is also amplified and feed to an output port of the chip to render possible cascading multiple chips for massive MIMO applications. The receivers each include a VGA to set the reference power level, a LNA for amplification of the weak antenna signal and the six-port structure with three broadside linecoupler, a wilkinson-divider and four power detectors. The transmitters each include a switched-line phase shifter and a power amplifier. The chip has a size of 4 mm x 3.1 mm and a power consumption of 960 mW from a 3.3 V power supply. A minimum input power of -22 dBm is needed at the input clock. The transmitters deliver a maximum output power of 9.1 dBm at 60 GHz. The phase is adjustable in a range from 0° to 325.4°. The successful measurement results indicate, that the MIMO six-port transceiver is well suited for radar applications.
Effect of omega-3 resource on glucose and total protein in ostriches.

The purpose of the study was to evaluate the effectiveness of the canola oil on the some metabolites ostriches. In order to study the metabolic profile of ostriches in relation to diet, Six blue-neck male ostriches (Struthio camelus) were fed omega-3 resource (canola oil =3%) throughout a 60-day experiment. Blood samples were collected from ostriches on days 0 and 60 of the experiment to measure levels of total serum protein, albumin, total immunoglobulin, cholesterol, the activity of ASP, ALT, insulin and glucose. The results showed that from days 0 to 60 of the experiment, glucose and total protein levels increased significantly (P<0.05). whereas total immunoglobulins insulin, albumin, ALT and AST did not change.
Cell Determination During Embryogenesis in Citrus jambhiri. I. Ontogeny of the Epidermis

Epidermal features are present in the embryo of the rough lemon, Citrus jambhiri, from the zygotic stage. The zygote, or nucellar progenitor in adventive embryos, is cuticularized. As derivatives are cut off to the inside of the periphery, they gradually diverge ultrastructurally in plastid structure and wall characteristics from the protodermal cells. Periclinal divisions continue in the surface cells of the root-hypocotyl axis until the heart-shaped stage, at which point cell divisions become confined to the anticlinal plane. We propose that the zygote and all subsequent surface derivatives are epidermal in nature, while internal derivatives diverge from epidermal to form the ground and vascular systems. The presence of cuticle and restriction of cell division to the anticlinal plane in the outer tunica of the shoot apical meristem support the conclusion that this layer is a previously formed epidermis.
Loss Reduction in Microstrip Antenna Using Different Methods

This paper presents a survey of various techniques to reduce the losses in the microstrip patch antenna. The designed antenna structures include several methods to reduce antenna losses in a microstrip antenna. Some of the methods such as multiple layered patches in microstrip antenna also increase its directivity by 4.2 dB. By using double negative substrate mutual coupling can be reduced by 14.2dB at the resonant frequency of 4.55GHz. The concept of an engineered conductor method which is based on using multiple laminated thin conductors is used for enhancing their gain by minimizing the ohmic loss. Experimental results are discussed to validate the concept.
An Energy Aware and Secure Fuzzy Logic Based Clustering Algorithm For Wireless Sensor Networks

Energy efficient and secure transmission act as two major issues in Wireless sensor networks(WSN). Moreover, WSN consists of energy constrained sensor nodes and thus to enhance the network lifetime the energy level at the each of the node must be preserved. The clustering mechanism act as one of the primary solution to address the problem of energy consumption in the WSN. The major drawback in the existing clustering algorithms is all the nodes are considered as trustworthy nodes which are not true. However, security is one the important design issues in WSN it becomes necessary to address the security aspect during the process of clustering. Trust based mechanism is promising approach to ensure secure transmission. Hence, in this paper trust based security model is proposed to address the security issues caused by the malicious nodes and to elect a trustworthy node as Cluster Leader (CL). Therefore, an integrated trust aware and energy efficient algorithm namely Fuzzy Logic based Energy Aware Secure Clustering algorithm (FBEASC) for effective election of trustworthy and energy efficient node as Cluster leader (CL) is proposed . The simulation results shows that the proposed work provides better results in terms of enhancing network life time and secure transmission of data when compared to other existing works.
Whispering to Industrial IoT for converging multi-domain Network Programmability

Industrial Internet of Things (IoT) calls for not only highly reliable, quasi-deterministic and low-power networks, but also for more flexible and programmable networks to cope with operator's dynamics demands. Software Defined Networking (SDN) offers the high levels of flexibility and programmability that traditional distributed protocols cannot offer. In between a fully centralized SDN-on-IoT management solution and a traditional fully distributed one, Whisper stands out as a tradeoff solution that has the robustness, scalability and low-overhead of distributed solutions and the flexibility and programmability of centralized ones. In this demo we present a hands-on experience of how Whisper can be jointly used with traditional SDN solutions, such as ONOS, in order to extend the already existing network programmability in wired domains to 6TiSCH-based Industrial IoT segments. We deploy and test such architecture in real-world large-scale testbeds and demonstrate to be feasible and beneficial to provide an efficient and programmable end-to-end control over a heterogeneous network.
Service Rating Prediction by check-in and check-out behavior of user and POI

Trophic position and potential food sources of 2 species of unionid bivalves (Mollusca:Unionidae) in 2 small Ohio streams

Abstract We determined the trophic positions of 2 species of freshwater mussels, Elliptio dilatata and Ptychobranchus fasciolaris, from 2 small streams in central Ohio by measuring stable C and N isotope ratios and digestive fluid enzyme activities. We also examined stable C and N isotopes, microbial biomass, microbial community structure, nutrient (i.e., C, N, and P) concentrations, and contribution of microbial C to total fine particulate organic C (FPOC). We hypothesized that 1) allochthonous inputs compose most of FPOC, 2) mussels use fine particulate organic material (FPOM) as a food source, and 3) mussels respond to the low-protein content of FPOM by showing high protease activity. Microbial C composed 35 to 86% of total FPOC during the autumn sampling period. FPOM stable isotope values varied seasonally, whereas δ13C and δ15N content in mussel tissue was spatially (i.e., among sites) and temporally similar. Mussels were 2 to 4‰ more depleted in δ13C than seasonal FPOM. Digestive fluid enzymes were spatially and temporally stable across species, with activity of esterase > protease > lipase > glucosidase. Lipase:protease of digestive fluids from mussels were <1, indicating a low-protein diet. Our results suggest that microbial biomass in FPOM constitutes a large portion of mussel diet and that mussels assimilate significant amounts of C from this source.

An Auto m ated Input Generation Method for Crawling of Web Applications

— Even though many tools provide automatic crawling, sometimes web applications are crawled manually in case of testing. The manual crawling takes much time and effort because it requires the construction of appropriate input sequences. To solve this problem, we proposed and developed an automated input generation method that performs manual crawling. This method employs an obser v e-select-execute cycle. The cycle enables us to automatically generate consecutive inputs for crawling which changes the states signiﬁcantly while analyzing the target web application. The paper also demonstrates our method by measuring the server-side code coverage and compares with the manual crawling. As a result, our method covered 47.58% on average, which is close to the 50.21% manual coverage.
Use of transgenic plants to study the role of ethylene and polygalacturonase during infection of tomato fruit by Colletotrichum gloeosporioides

The infection of tomato fruit by the postharvest pathogen Colletotrichum gloeosporioides did not proceed until the onset of ripening in response to ethylene. Compared with fruit from wild-type plants, infection progressed more slowly in transgenic fruit in which ethylene biosynthesis and ripening had been inhibited by an ACC oxidase (ACO) antisense transgene. In contrast, transgenic fruit deficient in polygalacturonase developed lesions at the same rate as the wild-type fruit. Ethylene biosynthesis increased rapidly in response to infection of ripe wild-type and ACO antisense fruit but was 25 times greater in the former. Fruit from the ripening mutant ripening inhibitor (rin), which are normally very resistant to infection, became infected quickly when incubated in the presence of ethylene, whereas fruit incubated in the absence of ethylene remained healthy. The ACO 1 mRNA accumulated to detectable levels within 24 h of inoculation of unripe wild-type fruit, prior to the development of visible symptoms, whereas there was no detectable expression in the inoculated ACO antisense fruit. ACO transcripts accumulated to maximum levels during the early stages of infection of ripe fruit, correlating with maximum ethylene biosynthesis. Northern analysis using gene-specific probes for each of the three ACO genes indicated that ACO 1 was the main gene expressed in response to infection and that there was no detectable expression of ACO 2 and 3.
Isolation of the encoding gene for a thermostable α- glucosidase from Geobacillus stearothermophilus strain RM and its expression in Escherichia coli

High temperature catalysis increases substrate solubility and carbohydrate hydrolysis, therefore investigating new thermostable α-glucosidase is an attractive option. A total of seven isolates were obtained from two different hot spring locations in Malaysia, namely Telaga Air Hangat Langkawi and Slim River. Preliminary study on four selected isolates revealed that production media 1 (PM 1) and production media 2 (PM 2) were the best media to support α-glucosidase production. The optimum growth temperatures were 50-70°C while their optimum temperature for α-glucosidase production was 55°C. Quantitative screening indicated that isolate L3 which was identified as Geobacillus stearothermophilus strain RM was the best α-glucosidase producer with 1.47 U/ml at 55°C after 72 h. The production of α-glucosidase was also found to be growth associated up to stationary phase. Identification on the basis of morphological characteristics, biochemical studies and 16S rRNA analysis were carried out and 16S rRNA identification revealed that this isolate showed 99% similarity to G. stearothermophilus. The α-glucosidase gene had been successfully amplified from this identified bacterium via degenerate primer and the complete gene was cloned and expressed into Escherichia coli with 5 U/ml activity which was 5-folds higher compared to the wild type. As a conclusion, E. coli system successfully increased the yield of α-glucosidase production.
Potent Inhibition of Herpes Simplex Virus by MDL 101028, a Novel Biphenyl Disulfonic Acid Urea Co-Polymer

A novel low-molecular-weight sulfonic acid polymer, MDL 101028, was investigated for antiviral activity against herpes simplex virus (HSV) type 1 and type 2 in human embryonic diploid fibroblasts (MRC-5) and in a line of monkey kidney cells (Vero). Potent antiviral activities were obtained when treatment was restricted to the adsorption phase of virus propagation as measured by plaque reduction assay, and this was confirmed by experiments at high multiplicity of infection. Inhibition of virus binding to host cells by MDL 101028 was compared to that of heparin, a known antagonist of virus attachment. Both compounds showed dose-dependent inhibition, with IC50 values of 1.1 and 0.43 μg ml−1, respectively. The effect on cell-to-cell fusion was investigated using a syncytial-positive (syn+) phenotypic mutant of HSV-1 (strain 17i). MDL 101028 (3-1 μm) dramatically halted the spread of syncytial lesions; this effect was accompanied by the destruction of the syncytium and regrowth into the lesion by uninfected Vero cells. In contrast, heparin (10 μg ml−1) only partially reduced the spread of syncytia. Protection was also observed with MDL 29797 (100 μg ml−1), an antagonist of glycoprotein maturation. Unexpectedly, only a marginal effect was observed with acyclovir (10 μg ml−1), a potent inhibitor of viral DNA synthesis and HSV growth. As an extension to the current therapy for herpes simplex infection, acyclovir, the potent anti-fusion activity of MDL 101028 may have a clinical use in tissues or organs in which cell-to-cell fusion contributes to the pathology.
The Structure of Photosynthetic Succulent Stems in Plants Other Than Cacti

In an investigation of succulence as an adaptation to water‐stressed desert environments, we studied the anatomy of photosynthetic succulent stems in 28 species from Apocynaceae, Asclepiadaceae, Asteraceae, Crassulaceae, Didieriaceae, Euphorbiaceae, Geraniaceae, and Vitaceae. Only species with enlarged pith or cortex were examined, not species with enlarged parenchymatous wood. The numbers of species with particular characters are as follows: pith is the most voluminous tissue—5 species; cortex is the most voluminous tissue—22; cortical bundles present—0; medullary bundles present—4; palisade cortex present—16; epidermis with thick or lignified walls—0; epidermis outer wall somewhat thickened—6; multiple epidermis present—0; cuticle >2 μm thick—4; cuticle <1 μm thick—3; hypodermis cells with very thick walls—0. These species lack many features typically considered xeromorphic and associated with desert‐adapted plants; they also lack many features present in most cacti. Absence of cortical bundles in all these noncactus succulents may be especially important: none has a particularly thick cortex (most are <5 mm thick), all are relatively small plants, and absence of cortex vascularization may prevent them from evolving to be truly voluminous. Also, none has truly large shoot apical meristems such as occur in cacti with broad shoots.
New insights into hepatitis B virus biology and implications for novel antiviral strategies

Hepatitis B virus (HBV), a small DNA virus with a unique replication mode, can cause chronic hepatitis (CHB), which is characterized by the persistence of the viral covalently closed circular DNA that serves as the template for HBV replication and the production of large amounts of secreted HBV surface antigen (HBsAg) that is present in excess of the levels of infectious virus. Despite the success of currently approved antiviral treatments for CHB patients, including interferon and nucleotide analogs, which suppress HBV replication and reduce the risk of CHB-related liver diseases, these therapies fail to eradicate the virus in most of the patients. With the development of the cell and animal models for HBV study, a better understanding of the HBV life cycle has been achieved and a series of novel antiviral strategies that target different stages of HBV replication have been designed to overcome the viral factors that contribute to HBV persistence. Such basic HBV research advancements and therapeutic developments are the subject of this review.
Secure Hashing Communication Algorithm for Wireless Data Access Scheme in WSN

—In Wireless Applications, decreasing both access latency and traffic volume is necessary. A Fast Data Access Scheme for Wireless Applications is proposed in which data are periodically modified and it is indispensable that data is accessed instantaneously. Depending upon the data popularity, distinct operation modes are defined and only the most popular data are proactively moved to Base station to lessen the network traffic. Hence a systematic model is developed, and an Operation Selection Algorithm is introduced to decrease the access latency. A Secured Hashing Communication Algorithm (SHCA) is used to check the authenticity of the base station as well as application server node and also if any malicious node is introduced which interrupts the network by sending erroneous messages, increases the access latency. Therefore, an analytical model is derived to check the authenticity of the node which gradually reduces the access latency. The main objective is to detect malicious node and to show the effect of network performance in presence of malicious node
CAUSES OF SUCCESS IN HANDBALL THROUGH THE BELIEFS ABOUT ABILITY CAUSAS DEL ÉXITO EN BALONMANO A TRAVÉS DE LAS CREENCIAS SOBRE HABILIDAD

The aim of this study was to determine the prediction ability of the implicit beliefs about ability over the beliefs about the causes of success in sports. The sample was comprised of 444 high performance athletes (233 boys and 211 girls; M = 16,70; SD = 0,49). These athletes completed the Spanish version of the Beliefs Rev.int.med.cienc. act. fís. deporte vol. 20 número 77 ISSN: 1577-0354 104 about the Causes of Success in Sports Questionnaire and the Conceptions of the Nature of Athletic Ability Questionnaire-2. The results revealed that beliefs of incremental ability predict effort, while beliefs about ability as an entity predict ability and deception as causes of success in handball.
Operation of Near-Field Scanning Millimeter-wave Microscopy up to 67 GHz under Scanning Electron Microscopy Vision

A near-field scanning millimeter-wave microscope is developed with broadband capabilities up to 67 GHz. The instrumentation has been designed to operate inside a scanning electron microscope for environment control and water meniscus elimination. Scanning electron microscopy imaging of the tip / sample interaction gives the unique possibility to limit the scan area and preserve the integrity of the probe tip. In addition, hybrid imaging considering simultaneously atomic, microwave and electron microscopy tools is beneficial for further modeling to address the quantitative characterization of nanomaterials. Experimental data are exemplary shown to demonstrate the viability of the solution proposed.
The On-Farm and Near-Farm Effects of Wind Turbines on Agricultural Land Values

We estimate the effects of utility-scale wind turbines on agricultural land values in Kansas using parcel-level transaction data from 2001 to 2017 in a hedonic price model. By matching transaction data and wind turbine data at the common land units scale, we are able to ascertain on-farm effects as well as near-farm effects. Across all our analyses, the preponderance of results suggests that wind turbines do not affect agricultural property values, both on-farm and nearby, in a statistically significant way. Thus, our results cannot confirm that wind turbines will increase land values when installed on a parcel.
