Automatic and Manual Web Annotations in an Infrastructure to handle Fake News and other Online Media Phenomena

Online media are ubiquitous and consumed by billions of people globally. Recently, however, several phenomena regarding online media have emerged that pose a severe threat to media consumption and reception as well as to the potential of manipulating opinions and, thus, (re)actions, on a large scale. Lumped together under the label “fake news”, these phenomena comprise, among others, maliciously manipulated content, bad journalism, parodies, satire, propaganda and several other types of false news; related phenomena are the often cited ﬁlter bubble (echo chamber) effect and the amount of abusive language used online. In an earlier paper we describe an architectural and technological approach to empower users to handle these online media phenomena. In this article we provide the ﬁrst approach of a metadata scheme to enable, eventually, the standardised annotation of these phenomena in online media. We also show an initial version of a tool that enables the creation, visualisation and exploitation of such annotations.
Broad-band transmission spectrum and K-band thermal emission of WASP-43b as observed from the ground

Aims. WASP-43b is the closest-orbiting hot Jupiter, and it has high bulk density. It causes deep eclipse depths in the system's light curve in both transit and occultation that is attributed to the cool temperature and small radius of its host star. We aim to secure a broad-band transmission spectrum and to detect its near-infrared thermal emission in order to characterize its atmosphere.
Lack of a Cytoplasmic RLK, Required for ROS Homeostasis, Induces Strong Resistance to Bacterial Leaf Blight in Rice

Many scientific findings have been reported on the beneficial function of reactive oxygen species (ROS) in various cellular processes, showing that they are not just toxic byproducts. The double-edged role of ROS shows the importance of the regulation of ROS level. We report a gene, rrsRLK (required for ROS-scavenging receptor-like kinase), that encodes a cytoplasmic RLK belonging to the non-RD kinase family. The gene was identified by screening rice RLK mutant lines infected with Xanthomonas oryzae pv. oryzae (Xoo), an agent of bacterial leaf blight of rice. The mutant (ΔrrsRLK) lacking the Os01g02290 gene was strongly resistant to many Xoo strains, but not to the fungal pathogen Magnaporthe grisea. ΔrrsRLK showed significantly higher expression of OsPR1a, OsPR1b, OsLOX, RBBTI4, and jasmonic acid-related genes than wild type. We showed that rrsRLK protein interacts with OsVOZ1 (vascular one zinc-finger 1) and OsPEX11 (peroxisomal biogenesis factor 11). In the further experiments, abnormal biogenesis of peroxisomes, hydrogen peroxide (H2O2) accumulation, and reduction of activity of ROS-scavenging enzymes were investigated in ΔrrsRLK. These results suggest that the enhanced resistance in ΔrrsRLK is due to H2O2 accumulation caused by irregular ROS-scavenging mechanism, and rrsRLK is most likely a key regulator required for ROS homeostasis in rice.
Security Threats and Privacy Issues in Vehicular Ad-Hoc Network (VANET): Survey and Perspective

In Vehicular Ad Hoc Networks (VANETs) Wireless-equipped vehicles are able to communicate with each other as well as Road-Side Units (RSUs) located at strategic places on the road, this enables the formation of self-organized networks connecting the vehicles and RSUs. The (vehicles) nodes are fast mobile causing the network topology to change frequently and unpredictably. Since VANETs do not really rely on any form of central administration or control, nodes in the wireless range dynamically discover each other and establish connection with each other. Due to the pervasive nature of the mobile nodes, it cannot be assumed that VANETs will always be under the control of their owners; nodes could be stolen or tampered with. Each vehicle (node) acts as an independent router and fault detection and network management becomes distributed and more difficult. The shared wireless medium is accessible to both legitimate and illegitimate users; and this has raise formidable research challenges to providing security for this network. This paper take a selective review of the published research work carried out in the security and privacy issue of VANET between 2003 and 2015 and derived a new perspective into the security and privacy attacks in VANET.
Targeting prostate cancer: Prostate‐specific membrane antigen based diagnosis and therapy

The high incidence rates of prostate cancer (PCa) raise demand for improved therapeutic strategies. Prostate tumors specifically express the prostate‐specific membrane antigen (PSMA), a membrane‐bound protease. As PSMA is highly overexpressed on malignant prostate tumor cells and as its expression rate correlates with the aggressiveness of the disease, this tumor‐associated biomarker provides the possibility to develop new strategies for diagnostics and therapy of PCa. Major advances have been made in PSMA targeting, ranging from immunotherapeutic approaches to therapeutic small molecules. This review elaborates the diversity of PSMA targeting agents while focusing on the radioactively labeled tracers for diagnosis and endoradiotherapy. A variety of radionuclides have been shown to either enable precise diagnosis or efficiently treat the tumor with minimal effects to nontargeted organs. Most small molecules with affinity for PSMA are based on either a phosphonate or a urea‐based binding motif. Based on these pharmacophores, major effort has been made to identify modifications to achieve ideal pharmacokinetics while retaining the specific targeting of the PSMA binding pocket. Several tracers have now shown excellent clinical usability in particular for molecular imaging and therapy as proven by the efficiency of theranostic approaches in current studies. The archetypal expression profile of PSMA may be exploited for the treatment with alpha emitters to break radioresistance and thus to bring the power of systemic therapy to higher levels.
Costs of a Practice‐based Air Quality Regulation: Dairy Farms in the San Joaquin Valley

&NA; Facing the difficulty of accurately measuring pollution from agriculture, economists have recommended regulatory approaches using proxies such as management practices to reduce agricultural pollution. Using farm‐level cost data on a panel of dairy farms, I estimate the effects of a practice‐based air quality regulation for dairy farms in the San Joaquin Valley in California. As opposed to ex ante analyses, my econometric results indicate that the air quality regulation has not significantly affected the total costs of milk production. Estimates also suggest that the regulation might have differential effects on different elements of costs. I support the econometric findings with evidence on how dairy farms comply with the regulation. Calculated adoption rates of different pollution‐mitigation practices using administrative data reveal that dairy farms have mainly adopted labor‐intensive practices to comply with the regulation.
Generation and Proteome Profiling of PBMC-Originated, iPSC-Derived Corneal Endothelial Cells

Purpose Corneal endothelial cells (CECs) are critical in maintaining clarity of the cornea. This study was initiated to develop peripheral blood mononuclear cell (PBMC)-originated, induced pluripotent stem cell (iPSC)-derived CECs. Methods We isolated PBMCs and programmed the mononuclear cells to generate iPSCs, which were differentiated to CECs through the neural crest cells (NCCs). The morphology of differentiating iPSCs was examined at regular intervals by phase contrast microscopy. In parallel, the expression of pluripotent and corneal endothelium (CE)-associated markers was investigated by quantitative real-time PCR (qRT-PCR). The molecular architecture of the iPSC-derived CECs and human corneal endothelium (hCE) was examined by mass spectrometry–based proteome sequencing. Results The PBMC-originated, iPSC-derived CECs were tightly adherent, exhibiting a hexagonal-like shape, one of the cardinal characteristics of CECs. The CE-associated markers expressed at significantly higher levels in iPSC-derived CECs at days 13, 20, and 30 compared with their respective levels in iPSCs. It is of importance that only residual expression levels of pluripotency markers were detected in iPSC-derived CECs. Cryopreservation of iPSC-derived CECs did not affect the tight adherence of CECs and their hexagonal-like shape while expressing high levels of CE-associated markers. Mass spectrometry–based proteome sequencing identified 10,575 proteins in the iPSC-derived CEC proteome. In parallel, we completed proteome profiling of the hCE identifying 6345 proteins. Of these, 5763 proteins were identified in the iPSC-derived CECs, suggesting that 90.82% of the hCE proteome overlaps with the iPSC-derived CEC proteome. Conclusions We have successfully developed a personalized approach to generate CECs that closely mimic the molecular architecture of the hCE. To the best of our knowledge, this is the first report describing the development of PBMC-originated, iPSC-derived CECs.
Alterations of the Global Water Cycle and their Effects on River Structure, Function and Services

Abstract River structure and functioning are governed naturally by geography and climate but are vulnerable to natural and human-related disturbances, ranging from channel engineering to pollution and biological invasions. Biological communities in river ecosystems are able to respond to disturbances faster than those in most other aquatic systems. However, some extremely strong or lasting disturbances constrain the responses of river organisms and jeopardise their extraordinary resilience. Among these, the artificial alteration of river drainage structure and the intense use of water resources by humans may irreversibly influence these systems. The increased canalisation and damming of river courses interferes with sediment transport, alters biogeochemical cycles and leads to a decrease in biodiversity, both at local and global scales. Furthermore, water abstraction can especially affect the functioning of arid and semi-arid rivers. In particular, interception and assimilation of inorganic nutrients can be detrimental under hydrologically abnormal conditions. Among other effects, abstraction and increased nutrient loading might cause a shift from heterotrophy to autotrophy, through direct effects on primary producers and indirect effects through food webs, even in low-light river systems. The simultaneous desires to conserve and to provide ecosystem services present several challenges, both in research and management.
KDM2B is a histone H3K79 demethylase and induces transcriptional repression via sirtuin‐1‐mediated chromatin silencing

The methylation of histone H3 lysine 79 (H3K79) is an active chromatin marker and is prominent in actively transcribed regions of the genome; however, demethylase of H3K79 remains unknown despite intensive research. Here, we show that KDM2B, also known as FBXL10 and a member of the Jumonji C family of proteins known for its histone H3K36 demethylase activity, is a di‐ and trimethyl H3K79 demethylase. We demonstrate that KDM2B induces transcriptional repression of HOXA7and MEIS1 via occupancy of promoters and demethylation of H3K79. Furthermore, genome‐wide analysis suggests that H3K79 methylation levels increase when KDM2B is depleted, which indicates that KDM2B functions as an H3K79 demethylase in vivo. Finally, stable KDM2B‐ knockdown cell lines exhibit displacement of NAD+‐dependent deacetylase sirtuin‐1 (SIRT1) from chromatin, with concomitant increases in H3K79 methylation and H4K16 acetylation. Our findings identify KDM2B as an H3K79 demethylase and link its function to transcriptional repression via SIRT1‐mediated chromatin silencing. —Kang, J.‐Y. , Kim, J.‐Y. , Kim, K. ‐B. , Park, J.

Effects of Flow Restoration and Exotic Species Removal on Recovery of Native Fish: Lessons from a Dam Decommissioning

Flow diversion and invasive species are two major threats to freshwater ecosystems, threats that restoration efforts attempt to redress. Yet, few restoration projects monitor whether removal of these threats improve target characteristics of the ecosystem. Fewer still have an appropriate experimental design from which causal inferences can be drawn as to the relative merits of removing exotic fish, restoring flow, or both. We used a dam decommissioning in Fossil Creek, Arizona, to compare responses of native fish to exotic fish removal and flow restoration, using a before‐after‐control‐impact design with three impact treatments: flow restoration alone where exotics had not been present, flow restoration and exotic fish removal, and flow restoration where exotics remain and a control reach that was unaffected by restoration actions. We show that removal of exotic fish dramatically increased native fish abundance. Flow restoration also increased native fish abundance, but the effect was smaller than that from removing exotics. Flow restoration had no effect where exotic fish remained, although it may have had other benefits to the ecosystem. The cost to restore flow ($12 million) was considerably higher than that to eradicate exotics ($1.1 million). The long‐term influence of flow restoration could increase, as travertine dams grow and re‐shape the creek increasing habitat for native fish. But in the 2‐year period considered here, the return on investment for extirpating exotics far exceeded that from flow restoration. Projects aimed to restore native fish by restoring flow should also consider the additional investment required to eradicate exotic fish.
Reduction-Triggered Transformation of Disulfide-Containing Micelles at Chemically Tunable Rates.

A dilemma exists between the circulation stability and cargo release/mass diffusion at desired sites when designing delivery nanocarriers and in vivo nanoreactors. Reported herein are disulfide-crosslinked (DCL) micelles exhibiting reduction-triggered switching of crosslinking modules and synchronized hydrophobic-to-hydrophilic transition. Tumor cell targeted DCL micelles undergo cytoplasmic milieu triggered disulfide cleavage and self-immolative decaging reactions at chemically adjustable rates, generating primary amine moieties. Extensive amidation reactions with neighboring ester moieties then occur because of the high local concentration and suppression of the apparent amine pKa value within the hydrophobic cores, thus leading to the transformation of crosslinking modules and formation of tracelessly crosslinked (TCL) micelles, with hydrophilic cores, inside live cells. We further integrate this design principle with theranostic nanocarriers for selective intracellular drug transport guided by enhanced magnetic resonance (MR) imaging performance.
Development and testing of the Youth Alcohol Norms Survey (YANS) instrument to measure youth alcohol norms and psychosocial influences

Objectives This study aimed to develop and validate an online instrument to: (1) identify common alcohol-related social influences, norms and beliefs among adolescents; (2) clarify the process and pathways through which proalcohol norms are transmitted to adolescents; (3) describe the characteristics of social connections that contribute to the transmission of alcohol norms; and (4) identify the influence of alcohol marketing on adolescent norm development. Setting The online Youth Alcohol Norms Survey (YANS) was administered in secondary schools in Western Australia Participants Using a 2-week test–retest format, the YANS was administered to secondary school students (n=481, age=13–17 years, female 309, 64.2%). Primary and secondary outcome measures The development of the YANS was guided by social cognitive theory and comprised a systematic multistage process including evaluation of content and face validity. A 2-week test–retest format was employed. Exploratory factor analysis was conducted to determine the underlying factor structure of the instrument. Test–retest reliability was examined using intraclass correlation coefficient (ICC) and Cohen’s kappa. Results A five-factor structure with meaningful components and robust factorial loads was identified, and the five factors were labelled as ‘individual attitudes and beliefs’, ‘peer and community identity’, ‘sibling influences’, ‘school and community connectedness’ and ‘injunctive norms’, respectively. The instrument demonstrated stability across the test–retest procedure (ICC=0.68–0.88, Cohen’s kappa coefficient=0.69) for most variables. Conclusions The results support the reliability and factorial validity of this instrument. The YANS presents a promising tool, which enables comprehensive assessment of reciprocal individual, behavioural and environmental factors that influence alcohol-related norms among adolescents.
Culture and Sexual Self-Disclosure in Intimate Relationships

Sexual self-disclosure is one of the most intimate forms of self-disclosure. Yet, there is surprisingly little research on this topic compared to the voluminous research that exists on self-disclosure (in general). This is particularly surprising since sexual self-disclosure has been found to be correlated with sexual and marital satisfaction (Byers & Demmons, 2010). Conversations about sex have also been found to be critical in preventing HIV and other sexually transmitted infections, expressing sexual consent, and sexual desires and satisfaction (Faulkner & Lannutti, 2010). Nor have scholars investigated the impact of culture on people’s willingness to engage in sexual self-disclosure. In this paper, we will review current theorizing as to the extent to which culture and gender might be expected to influence young people’s willingness to sexually self-disclose, and suggest possible directions that future research might take.
DNA activates the Nse2/Mms21 SUMO E3 ligase in the Smc5/6 complex

Modification of chromosomal proteins by conjugation to SUMO is a key step to cope with DNA damage and to maintain the integrity of the genome. The recruitment of SUMO E3 ligases to chromatin may represent one layer of control on protein sumoylation. However, we currently do not understand how cells upregulate the activity of E3 ligases on chromatin. Here we show that the Nse2 SUMO E3 in the Smc5/6 complex, a critical player during recombinational DNA repair, is directly stimulated by binding to DNA. Activation of sumoylation requires the electrostatic interaction between DNA and a positively charged patch in the ARM domain of Smc5, which acts as a DNA sensor that subsequently promotes a stimulatory activation of the E3 activity in Nse2. Specific disruption of the interaction between the ARM of Smc5 and DNA sensitizes cells to DNA damage, indicating that this mechanism contributes to DNA repair. These results reveal a mechanism to enhance a SUMO E3 ligase activity by direct DNA binding and to restrict sumoylation in the vicinity of those Smc5/6‐Nse2 molecules engaged on DNA.
Perceived need and help-seeking in adults with mood, anxiety, or substance use disorders.

BACKGROUND A majority of adults with common mental disorders do not seek professional help. To better understand why not, we examined the correlates of various stages of help-seeking, including perceived need for professional help, seeking such help, and from which professionals participants sought help. METHODS The sample for this study comprised 1792 participants in the National Comorbidity Survey, conducted from 1990-1992, who were diagnosed with a 12-month DSM-III-R mood, anxiety, or substance disorder. In this sample, we assessed correlates of perceived need for professional help, seeking professional help among those with a need, and, among those who did seek professional help, seeking help from mental health professionals. RESULTS Mood disorders, comorbid mood and anxiety disorders, and mental disorders associated with impairment in role functioning or suicidality were strong predictors of perceived need. Psychopathology was also associated with the decision to seek help from mental health professionals, but not with the decision to seek professional help overall. After controlling for the nature and severity of psychopathology, various sociodemographic and attitudinal factors appeared to be associated with perception of need, help-seeking, and participants' choices of professionals. CONCLUSIONS Unmet need for mental health care is a serious public health problem. Meeting this need requires expanding our attention beyond psychopathology to various evaluations and decisions that affect help-seeking. Our results suggest the importance of attitude and behavior change strategies in reducing the gap between need and care.
Framing Named Entity Linking Error Types

Named Entity Linking (NEL) and relation extraction forms the backbone of Knowledge Base Population tasks. The recent rise of large open source Knowledge Bases and the continuous focus on improving NEL performance has led to the creation of automated benchmark solutions during the last decade. The benchmarking of NEL systems offers a valuable approach to understand a NEL system’s performance quantitatively. However, an in-depth qualitative analysis that helps improving NEL methods by identifying error causes usually requires a more thorough error analysis. This paper proposes a taxonomy to frame common errors and applies this taxonomy in a survey study to assess the performance of four well-known Named Entity Linking systems on three recent gold standards.

Adenosine: Synthetic Methods of Its Derivatives and Antitumor Activity

Since 1929, several researchers have conducted studies in relation to the nucleoside of adenosine (1) mainly distribution identifying, characterizing their biological importance and synthetic chemistry to which this type of molecule has been subjected to obtain multiple of its derivatives. The receptors that interact with adenosine and its derivatives, called purinergic receptors, are classified as A1, A2A, A2B and A3. In the presence of agonists and antagonists, these receptors are involved in various physiological processes and diseases. This review describes and compares some of the synthetic methods that have been developed over the last 30 years for obtaining some adenosine derivatives, classified according to substitution processes, complexation, mating and conjugation. Finally, we mention that although the concentrations of these nucleosides are low in normal tissues, they can increase rapidly in pathophysiological conditions such as hypoxia, ischemia, inflammation, trauma and cancer. In particular, the evaluation of adenosine derivatives as adjunctive therapy promises to have a significant impact on the treatment of certain cancers, although the transfer of these results to clinical practice requires a deeper understanding of how adenosine regulates the process of tumorigenesis.
