Preserving identity privacy on multi‐owner cloud data during public verification
Authors: Wang Boyang , Li Hui , Liu Xuefeng , Li Xiaoqing , Li Fenghua 
Published: December 2013

ABSTRACTThe low prices on cloud data storage and sharing services incentive users to outsource their data to the cloud. Because data stored in the cloud may be lost or corrupted, users are suggested to verify data integrity before the utilization of cloud data. A series of schemes have been proposed to enable a public verifier to efficiently check the correctness of cloud data without downloading the whole data from the cloud server. Unfortunately, few of them have considered about public verification on multi‐owner cloud data while still preserving identity privacy of owners from public verifiers, where each block in these cloud data should be signed by multiple owners. In this paper, we design a novel public verification scheme to audit the integrity of multi‐owner data stored in the cloud. With our scheme, a public verifier is able to efficiently check the integrity of multi‐owner data with a very small communication cost compared with the size of the entire data. Meanwhile, the private identities of these owners are protected and not revealed to any public verifier. In addition, our scheme can also efficiently support group dynamics for multiple owners and enable batch verification. Security analyses and experimental results indicate our scheme is correct, secure and efficient. Copyright © 2013 John Wiley & Sons, Ltd.
Uncertainties of the 50‐year wind from short time series using generalized extreme value distribution and generalized Pareto distribution
Authors: Larsén Xiaoli Guo , Mann Jakob , Rathmann Ole , Jørgensen Hans E. 
Published: December 2013

ABSTRACTThis study examines the various sources to the uncertainties in the application of two widely used extreme value distribution functions, the generalized extreme value distribution (GEVD) and the generalized Pareto distribution (GPD). The study is done through the analysis of measurements from several Danish sites, where the extreme winds are caused by the Atlantic lows. The simple extreme wind mechanism here helps us to focus on the issues mostly related to the use of limited wind measurements. Warnings are flagged and possible solutions are discussed. Thus, this paper can be used as a guideline for applying GEVD and GPD to wind time series of limited length. The data analysis shows that, with reasonable choice of relevant parameters, GEVD and GPD give consistent estimates of the return winds. For GEVD, the base period should be chosen in accordance with the occurrence of the extreme wind events of the same mechanism. For GPD, the choices of the threshold, the definition of independent samples and the shape factor are interrelated. It is demonstrated that the lack of climatological representativity is a major source of uncertainty to the use of both GEVD and GPD; the information of climatological variability is suggested to be extracted from global or mesoscale models. © 2013 The Authors.Wind Energypublished by John Wiley & Sons, Ltd.
Metaphysical analyticity and the epistemology of logic
Authors: Russell Gillian K. 
Published: December 2013

AbstractRecent work on analyticity distinguishes two kinds, metaphysical and epistemic. This paper argues that the distinction allows for a new view in the philosophy of logic according to which the claims of logic are metaphysically analytic and have distinctive modal profiles, even though their epistemology is holist and in many ways rather Quinean. It is argued that such a view combines some of the more attractive aspects of the Carnapian and Quinean approaches to logic, whilst avoiding some famous problems.
Discussions of adolescent sexuality in news media coverage of the HPV vaccine
Authors: Casciotti Dana M. , Smith Katherine C. , Tsui Amy , Klassen Ann C. 
Published: December 2013

ABSTRACTGiven the sexually transmitted nature of human papillomavirus (HPV), some worry the HPV vaccine will create a false sense of security and promote adolescent sexual activity. Media coverage of vaccines can influence social norms, parental attitudes, and vaccine acceptance; in this paper we examine U.S. news media messages related to sexuality and HPV vaccination. Drawing on a structured analysis of 447 articles published during 2005–2009, we qualitatively analyzed a purposive sample of 49 articles discussing adolescent health behaviors related to HPV vaccination. Commonly, articles discussed vaccination in the context of abstinence‐only versus comprehensive sexual health education; cited research findings to support vaccination or sex education; argued against connecting vaccination to promiscuous behavior; but included fear‐inducing messages. Media messages concerning health behaviors related to HPV vaccination tended to support government and parental involvement in sex education, and dismiss concerns linking vaccination to sexual activity, while also presenting the vaccine as lifesaving.
Wide‐stopband Wilkinson power divider with bandpass response
Authors: Chau W.‐M. , Hsu K.‐W. , Tu W.‐H. 
Published: December 2013

A wide‐stopband Wilkinson power divider with bandpass response and good isolation is presented. A 3‐terminal, 2‐pole bandpass filter and two 3‐pole lowpass filters are used to replace the two quarter‐wavelength transformer in a conventional Wilkinson power. The divider consists of two shorted‐circuited half‐wavelength stepped‐impedance resonators and two 3‐pole microstrip stepped‐impedance lowpass filters. Thus, the divider achieves not only a bandpass response but also a very wide stopband. For the upper stopband performance, the rejection level is >10 dB up to 22.2 times the centre frequency.
Awake reactivation predicts memory in humans
Authors: Staresina Bernhard P. , Alink Arjen , Kriegeskorte Nikolaus , Henson Richard N. 
Published: December 2013

Significance
How is new information converted into a memory trace? Here, we used functional neuroimaging to assess what happens to representations of new events after we first experience them. We found that a particular part of the medial temporal lobe, a brain region known to be critical for intact memory, spontaneously reactivates these events even when we are engaged in unrelated activities. Indeed, the extent to which such automatic reactivation occurs seems directly related to later memory performance. This finding shows that we can now study the dynamics of memory processes for specific experiences during the “offline” periods that follow the initial learning phase.
Cultural assemblages show nested structure in humans and chimpanzees but not orangutans
Authors: Kamilar Jason M. , Atkinson Quentin D. 
Published: December 2013

Significance
The evolution of culture is well-documented in the human archeological and fossil records, but equivalent data are absent for nonhuman primates. Here, we use modern variation to learn about processes of temporal evolution by measuring nestedness across human and great ape “cultural repertoires.” Cultural assemblages are nested if cultures with a small repertoire of traits tend to comprise a proper subset of traits present in more complex cultures. We find a significant degree of nestedness in human and chimpanzee cultural repertoires, but not for orangutans. Our findings are consistent with a sequential “layering” of culture in humans and chimpanzees only, suggesting that the traits required for sequential cultural evolution first appeared in the last common ancestor of these species.
Biologically derived melanin electrodes in aqueous sodium-ion energy storage devices
Authors: Kim Young Jo , Wu Wei , Chun Sang-Eun , Whitacre Jay F. , Bettinger Christopher J. 
Published: December 2013

Significance
Here we present important findings related to biologically derived pigments for potential use as battery electrodes. Namely, we report the synthesis, fabrication, and characterization of melanins as materials for use in aqueous sodium-ion batteries. We demonstrate the use of naturally occurring melanins as active electrode materials in charge storage devices. Furthermore, the performance of melanin anodes is comparable to many commonly available synthetic organic electrode materials. The structure–property relationships that govern the storage capacity in melanin materials were also elucidated. These findings suggest that the unique chemistry and nanostructure in natural melanins increase the charge storage capacity compared with synthetic melanin analogues.

Published: December 2013

Significance
Closed-loop systems, or brain–machine–brain interfaces (BMBIs), have not been widely developed for brain repair. In this study, we targeted spared motor and somatosensory regions of the rat brain after traumatic brain injury for establishment of a functional bridge using a battery-powered microdevice. The results show that by using discriminated action potentials as a trigger for stimulating a distant cortical location, rapid recovery of fine motor skills is facilitated. This study provides strong evidence that BMBIs can be used to bridge damaged neural pathways functionally and promote recovery after brain injury. Although this study is restricted to a rodent model of TBI, it is likely that the approach will also be applicable to other types of acquired brain injuries.
Visualization of repetitive DNA sequences in human chromosomes with transcription activator-like effectors
Authors: Ma Hanhui , Reyes-Gutierrez Pablo , Pederson Thoru 
Published: December 2013

Significance
Repetitive DNA sequences such as telomeres and centromeres are, like the chromosomes in which they reside, highly dynamic within the interphase nucleus, moving about by diffusion. Live cell imaging of these specific chromosomal sites has been limited and the approach presented in this study, based on expressed transcription activator-like effector (TALE)-fluorescent proteins, offers new opportunities in basic research on chromosome dynamics. In parallel, the described use of fluorescent TALEs as probes with fixed cells presents advantages over fluorescent in situ hybridization and may find particular applications in clinical and diagnostic settings.
Venting and Reef Fish Survival: Perceptions and Participation Rates among Recreational Anglers in the Northern Gulf of Mexico

Published: December 2013

Abstract
Fisheries scientists, managers, and industry have developed innovative tools and techniques to improve the survival of fishes captured and released in deepwater settings. Venting involves the insertion of a hollow needle to deflate a fish's swim bladder and is among the most widely promoted barotrauma mitigation techniques. However, its efficacy has been the subject of intense debate. In the northern Gulf of Mexico, venting tools are mandatory tackle for offshore reef anglers, but current mandates on usage are being reconsidered. We surveyed recreational and tournament anglers to understand the popularity and perceived effectiveness of venting and identify factors that affect these measures. Our survey results indicate that approximately two-thirds of anglers vent the fish they release offshore and most perceive it to be effective for improving survival rates. Among recreational anglers, we found that primary fishing locale (inshore, offshore) and experience were powerful predictors of perceptions and utilization rates. However, fishing experience did not appear to influence knowledge of proper venting techniques. While further ecological and physiological experimentation is needed to resolve many uncertainties that surround venting, our study demonstrates that angler perceptions and behaviors must also be considered and that aggressive education and outreach programs would be necessary to alter or improve current venting practices.

Characterization of two different Asf1 histone chaperones with distinct cellular localizations and functions in Trypanosoma brucei
Authors: Pascoalino Bruno , Dindar Gülcin , Vieira-da-Rocha João P. , Machado Carlos Renato , Janzen Christian J. , Schenkman Sergio 
Published: December 2013

AbstractThe anti-silencing function protein 1 (Asf1) is a chaperone that forms a complex with histones H3 and H4 facilitating dimer deposition and removal from chromatin. Most eukaryotes possess two different Asf1 chaperones but their specific functions are still unknown. Trypanosomes, a group of early-diverged eukaryotes, also have two, but more divergent Asf1 paralogs than Asf1 of higher eukaryotes. To unravel possible different functions, we characterized the two Asf1 proteins in Trypanosoma brucei. Asf1A is mainly localized in the cytosol but translocates to the nucleus in S phase. In contrast, Asf1B is predominantly localized in the nucleus, as described for other organisms. Cytosolic Asf1 knockdown results in accumulation of cells in early S phase of the cell cycle, whereas nuclear Asf1 knockdown arrests cells in S/G2 phase. Overexpression of cytosolic Asf1 increases the levels of histone H3 and H4 acetylation. In contrast to cytosolic Asf1, overexpression of nuclear Asf1 causes less pronounced growth defects in parasites exposed to genotoxic agents, prompting a function in chromatin remodeling in response to DNA damage. Only the cytosolic Asf1 interacts with recombinant H3/H4 dimers in vitro. These findings denote the early appearance in evolution of distinguishable functions for the two Asf1 chaperons in trypanosomes.

Published: December 2013

AbstractDeciphering the causal networks of gene interactions is critical for identifying disease pathways and disease-causing genes. We introduce a method to reconstruct causal networks based on exploring phenotype-specific modules in the human interactome and including the expression quantitative trait loci (eQTLs) that underlie the joint expression variation of each module. Closely associated eQTLs help anchor the orientation of the network. To overcome the inherent computational complexity of causal network reconstruction, we first deduce the local causality of individual subnetworks using the selected eQTLs and module transcripts. These subnetworks are then integrated to infer a global causal network using a random-field ranking method, which was motivated by animal sociology. We demonstrate how effectively the inferred causality restores the regulatory structure of the networks that mediate lymph node metastasis in oral cancer. Network rewiring clearly characterizes the dynamic regulatory systems of distinct disease states. This study is the first to associate an RXRB-causal network with increased risks of nodal metastasis, tumor relapse, distant metastases and poor survival for oral cancer. Thus, identifying crucial upstream drivers of a signal cascade can facilitate the discovery of potential biomarkers and effective therapeutic targets.
SIOMICS: a novel approach for systematic identification of motifs in ChIP-seq data
Authors: Ding Jun , Hu Haiyan , Li Xiaoman 
Published: December 2013

AbstractThe identification of transcription factor binding motifs is important for the study of gene transcriptional regulation. The chromatin immunoprecipitation (ChIP), followed by massive parallel sequencing (ChIP-seq) experiments, provides an unprecedented opportunity to discover binding motifs. Computational methods have been developed to identify motifs from ChIP-seq data, while at the same time encountering several problems. For example, existing methods are often not scalable to the large number of sequences obtained from ChIP-seq peak regions. Some methods heavily rely on well-annotated motifs even though the number of known motifs is limited. To simplify the problem, de novo motif discovery methods often neglect underrepresented motifs in ChIP-seq peak regions. To address these issues, we developed a novel approach called SIOMICS to de novo discover motifs from ChIP-seq data. Tested on 13 ChIP-seq data sets, SIOMICS identified motifs of many known and new cofactors. Tested on 13 simulated random data sets, SIOMICS discovered no motif in any data set. Compared with two recently developed methods for motif discovery, SIOMICS shows advantages in terms of speed, the number of known cofactor motifs predicted in experimental data sets and the number of false motifs predicted in random data sets.

Mechanisms of Acupuncture–Electroacupuncture on Persistent Pain
Authors: Zhang Ruixin , Lao Lixing , Ren Ke , Berman Brian M. 
Published: December 2013

Abstract
In the last decade, preclinical investigations of electroacupuncture mechanisms on persistent tissue injury (inflammatory), nerve injury (neuropathic), cancer, and visceral pain have increased. These studies show that electroacupuncture activates the nervous system differently in health than in pain conditions, alleviates both sensory and affective inflammatory pain, and inhibits inflammatory and neuropathic pain more effectively at 2 to 10 Hz than at 100 Hz. Electroacupuncture blocks pain by activating a variety of bioactive chemicals through peripheral, spinal, and supraspinal mechanisms. These include opioids, which desensitize peripheral nociceptors and reduce proinflammatory cytokines peripherally and in the spinal cord, and serotonin and norepinephrine, which decrease spinal N-methyl-d-aspartate receptor subunit GluN1 phosphorylation. Additional studies suggest that electroacupuncture, when combined with low dosages of conventional analgesics, provides effective pain management which can forestall the side effects of often-debilitating pharmaceuticals.
The spirited leader: the potential of spiritual intelligence to improve leadership
Authors: Hyson Peter 
Published: December 2013

Purpose
– Spiritual intelligence (SQi) plays a vital part in deepening leadership effectiveness and staff performance in the public sector. Spiritually intelligent leaders (SQLs) use SQi to develop leadership skills beyond just emotional intelligence.

Design/methodology/approach
– Studies of the characteristics of those commonly recognised as outstanding leaders consistently identify skills and qualities relating to the spirit or soul. The SQi metric identifies 21 such attributes and the ways in which they can be developed at five levels of competence. Their conscious deployment of four cornerstone skills keeps them focused and effective, motivates their staff and produces more effective results.

Findings
– This paper provides concrete explanations of the attributes of the SQL and expands on how these are key antidotes to dealing with the most frequently reported common leadership dilemma: demoralisation and loss of meaning.

Originality/value
– This paper will be of immediate value and practical application to those in public sector leadership roles who wish to develop their own leadership skills and the commitment of their staff.
Orientation and speed of wind gusts causing abscission of wind‐dispersed seeds influences dispersal distance
Authors: Savage David , Borger Catherine P. , Renton Michael 
Published: December 2013

Summary

Abscission of seeds in some plant species occurs as a result of strong wind gusts that exert sufficient drag forces to liberate the seed from its parent. This may be an adaptive feature, as release into stronger wind gusts has been shown to lead to greater dispersal distances, which is likely to have evolutionary advantages.

We test the hypotheses that (i) seeds released into upward wind gusts will, on average, travel further than those seeds released into wind gusts with horizontal or downward orientations and (ii) that the preferential abscission of seeds into upward wind gusts will result in the dispersal of seeds over greater distances.

As a case study, we studied the abscission dynamics of Conyza bonariensis (L.) Cronquist (fleabane), which is an important weed with global distribution. Using abscission data obtained through a series of seed release experiments, we confirm that abscission of seeds in C. bonariensis is most likely to occur during strong and upward wind gusts.

We demonstrate that, for a given wind speed, seeds released into upward wind gusts will, on average, travel further than those seeds released into wind gusts with horizontal or downward orientations. We also show that preferential release into upward wind gusts has some influence on the distance travelled, but the strength of this influence is dependent on the correlation between wind orientation and wind speed. For this particular study, the sensitivity of release to the horizontal wind speed seems to have a larger effect on the distance travelled than sensitivity to wind orientation.
Ablation of the creA regulator results in amino acid toxicity, temperature sensitivity, pleiotropic effects on cellular development and loss of virulence in the filamentous fungus Beauveria bassiana

Published: December 2013

SummaryFor most organisms, carbon and nitrogen uptake are essential for growth, development and, where applicable, pathogenesis. The role of the carbon catabolite repressor transcription factor homologue BbcreA in the entomopathogenic fungus Beauveria bassiana was investigated. Deletion of BbcreA resulted in pleiotropic effects, including nutrient toxicity, leading to a novel cell lytic phenotype. Fungal growth in rich media and minimal media containing select amino acids/peptides was severely compromised, with microscopic examination revealing conidial‐base germ tube degeneration and cell lysis occurring during growth, a phenomenon exacerbated at higher temperatures (32°C). Depending upon nutrient conditions, growth, pigment and aerial mycelium production, sporulation and dimorphic transition to blastospore production were also impaired in the ΔBbcreA strain. Although loss of BbcreA resulted in de‐repression of secreted protease and lipase, enzymes critical in mediating pathogenesis, insect bioassays indicated severe defects in virulence using both topical and intra‐haemocoel injection assays, with eruption and subsequent sporulation on host cadavers greatly reduced in the mutant. These data suggest that BbcreA functions as more than a carbon repressor and plays important roles in nutrient utilization, cell homeostasis and virulence. In particular, BbcreA is required for proper assimilation of select amino acids and peptides, including asparagine, arginine and proline.
