description: Wnt signaling is involved in developmental processes, cell proliferation, and cell migration. Secreted frizzled-related protein 4 (sFRP4) has been demonstrated to be a Wnt antagonist; however, its effects on endothelial cell migration and angiogenesis have not yet been reported. Using various in vitro assays, we show that sFRP4 inhibits endothelial cell migration and the development of sprouts and pseudopodia as well as disrupts the stability of endothelial rings in addition to inhibiting proliferation. sFRP4 interfered with endothelial cell functions by antagonizing the canonical Wnt/β-catenin signaling pathway and the Wnt/planar cell polarity pathway. Furthermore, sFRP4 blocked the effect of vascular endothelial growth factor on endothelial cells. sFRP4 also selectively induced apoptotic events in endothelial cells by increasing cellular levels of reactive oxygen species. In vivo assays demonstrated a reduction in vascularity after sFRP4 treatment. Most importantly, sFRP4 restricted tumor growth in mice by interfering with endothelial cell function. The data demonstrate sFRP4 to be a potent angiogenesis inhibitor that warrants further investigation as a therapeutic agent in the control of angiogenesis-associated pathology.

description: No abstracts are to be cited without prior reference to the author.A database of tallybooks, from skippers' own logbooks, provided by the French industry involved in deep-water fishing to the west of the British Isles was used to standardise blue ling Landings per Unit of Effort (LPUEs). The data covered the years 1992-2008 with more extensive data for the period 2000-2007. For each haul, landings by species, tow duration, depth and location were reported. Compared to EU logbooks, this database is on a haul by haul basis instead of being aggregated by fishing sub-trips combining hauls from the same day, ICES rectangle and gear. Moreover, it includes depth, which is a major factor for catch rates in deepwater fisheries. LPUEs were estimated from Generalised Additive Models (GAMs) with depth, vessel, statistical rectangle and zone by year as explanatory variables. Owing to the statistical distribution of landings rates, landings were modelled by a Tweedie distribution, which is a compound Poisson distribution and allows to handle data with many zeros, as it is typical for catch data. In order to investigate how to reliably track stock trends, LPUEs were estimated in five regions for different subsets including or not the spawning season, when blue ling aggregates, or considering tows where blue ling was only a bycatch. The results based on the tallybook data indicated that blue ling LPUEs have been mainly stable over the past decade. This is consistent with stable mean length in the landings. Haul by haul data are suitable to derive abundance indices for deep-water fisheries assessment.

description: It's well known that in conformal theories the two- and three-point functions of a subset of the local operators-the conformal primaries-suffice, via the operator product expansion (OPE), to determine all local correlation functions of operators. It's less well known that, in superconformal theories, the OPE of superdescendants is generally undetermined from those of the superprimaries, and there is no universal notion of superconformal blocks. We recall these and related aspects of 4d (S)CFTs, and then we focus on the super operator product expansion (sOPE) of conserved currents in 4d N=1 SCFTs. The current-current OPE J(x)J(0) has applications to general gauge mediation. We show how superconformal symmetry, when combined with current conservation, determines the OPE coefficients of superconformal descendants in terms of those of the superconformal primaries. We show that only integer-spin real superconformal primary operators of vanishing R-charge, and their descendants, appear in the sOPE. We also discuss superconformal blocks for four-point functions of the conserved currents.

Intrusion detection systems (Computer security)

description: Intrusion detection systems are fundamentally passive and fail-open. Because their primary task is classification, they do nothing to prevent an attack from succeeding. An intrusion prevention system (IPS) adds protection mechanisms that provide fail-safe semantics, automatic response capabilities, and adaptive enforcement. We present FLIPS (Feedback Learning IPS), a hybrid approach to host security that prevents binary code injection attacks. It incorporates three major components: an anomaly-based classifier, a signature-based filtering scheme, and a supervision framework that employs Instruction Set Randomization (ISR). Since ISR prevents code injection attacks and can also precisely identify the injected code, we can tune the classifier and the filter via a learning mechanism based on this feedback. Capturing the injected code allows FLIPS to construct signatures for zero-day exploits. The filter can discard input that is anomalous or matches known malicious input, effectively protecting the application from additional instances of an attack -- even zero-day attacks or attacks that are metamorphic in nature. FLIPS does not require a known user base and can be deployed transparently to clients and with minimal impact on servers. We describe a prototype that protects HTTP servers, but FLIPS can be applied to a variety of server and client applications.
High Cost, Little Compensation, No Harm to Deter: New Evidence On Class Actions Under Federal Consumer Protection Statutes

description: Working from a sample of all consumer class actions filed in the Northern District of Illinois during 2010–2012 (totaling 510), this Article reports and analyzes data on class actions under four federal consumer protection statutes, the Electronic Funds Transfer Act (“EFTA”), the Fair Credit Reporting Act (“FCRA”), the Fair Debt Collection Practices Act (“FDCPA”), and the Telephone Consumer Protection Act (“TCPA”). Even assuming that the TCPA cases alleged actual harm to the named plaintiff, over half the cases in the sample sought statutory damages without an allegation of harm to the plaintiff. Especially in large class actions, only 10% to 15% of the class received compensation, and the aggregate compensation paid to the class is far less than the stated or nominal class settlement fund amount. Because courts award attorneys’ fees based on the nominal settlement amount, attorneys’ fees are a very large fraction of the amount paid to the class, and for some case types attorneys’ fees average 300% to 400% of the amount paid to the class. With low class compensation rates and attorneys’ fees to class counsel that often dwarf total class compensation, such class actions are highly inefficient means of awarding compensation to consumers. As the actual harm in such cases is, at best, small, consumers would likely have little ex-ante demand for insurance against such harm. Because statutory damages are far greater than the actual harm and relatively uniform and independent of actual harm, the system likely leads to a misallocation of efforts of class counsel toward such high statutory damage cases and away from cases with bigger harm but smaller statutory damages. In Spokeo, Inc. v. Robins, 578 U.S. __ (2016), the Supreme Court recently articulated a test for standing in actions brought under precisely the sort of no-harm, statutory damage provisions studied here. This Article concludes by evaluating possible solutions to socially wasteful no-harm causes of action under federal consumer protection statutes. One possibility is that under Spokeo, courts could screen true no-harm cases from the costly class-action process. Another is that through better monitoring of class settlement terms, district courts could lower the costs of class actions and restore balance between costs and benefits. The final reform possibility analyzed in this Article is Congressional amendment of no-harm statutory damage provisions.

description: This article assesses the socioeconomic effects of solar microgrids. The lack of access to electricity is a major obstacle to the socioeconomic development of more than a billion people. Off-grid solar technologies hold potential as an affordable and clean solution to satisfy basic electricity needs. We conducted a randomized field experiment in India to estimate the causal effect of off-grid solar power on electricity access and broader socioeconomic development of 1281 rural households. Within a year, electrification rates in the treatment group increased by 29 to 36 percentage points. Daily hours of access to electricity increased only by 0.99 to 1.42 hours, and the confidence intervals are wide. Kerosene expenditure on the black market decreased by 47 to 49 rupees per month. Despite these strong electrification and expenditure effects, we found no systematic evidence for changes in savings, spending, business creation, time spent working or studying, or other broader indicators of socioeconomic development.

description: In this paper, we focus on the possibility to test General Relativity in the Solar System with radioscience measurements. To this aim, we present a new software that simulates Range and Doppler signals directly from the space-time metric. This flexible approach allows one to perform simulations in General Relativity and in alternative metric theories of gravity. In a second step, a least-squares fit of the different initial conditions involved in the situation is performed in order to compare anomalous signals produced by a given alternative theory with the ones obtained in General Relativity. This software provides orders of magnitude and signatures stemming from hypothetical alternative theories of gravity on radioscience signals. As an application, we present some simulations done for the Cassini mission in Post-Einsteinian Gravity and in the context of MOND External Field Effect. We deduce constraints on the Post-Einsteinian parameters but find that the considered arc of the Cassini mission is not useful to constrain the MOND External Field Effect.

Power estimation for diverse field programmable gate array architectures
Creators: name: Jeffrey, Goeders
Publisher: name: University of British Columbia
Year: 2012

description: This thesis presents a new power model, which is capable of modelling the power usage of many different field-programmable gate array (FPGA) architectures. FPGA power models have been developed in the past; however, they were designed for a single, simple architecture, with known circuitry. This work explores a method for estimating power usage for many different user-created architectures. This requires a fundamentally new technique. Although the user specifies the functionality of the FPGA architecture, the physical circuitry is not specified. Central to this work is an algorithm which translates these functional descriptions into physical circuits. After this translation to circuit components, standard methods can be used to estimate power dissipation. In addition to enlarged architecture support, this model also provides support for modern FPGA features such as fracturable look-up tables and hard blocks. Compared to past models, this work provides substantially more detailed static power estimations, which is increasingly relevant as CMOS is scaled to smaller technologies. The model is designed to operate with modern CMOS technologies, and is validated against SPICE using 22 nm, 45 nm and 130 nm technologies. Results show that for common architectures, roughly 73% of power consumption is due to the routing fabric, 21% from logic blocks and 3% from the clock network. Architectures supporting fracturable look-up tables require 3.5-14% more power, as each logic block has additional I/O pins, increasing both local and global routing resources.

description: Objective: To correlate neuropsychological testing with cerebrospinal fluid Amyloid beta (AD), tau and Ptau levels in patients with Mild Cognitive Impairment (MCI)
Background: Principal diagnostic instrument to define global cognitive state is the Mini Mental State Examination (MMSE). Cognitive domains that best predict progression from amnestic MCI to AD are episodic memory and executive functioning. Were selected two neuropsychological tests for both domains: Story Recall Test (SRT) and Paired-Associate Learning (PAL) to examine episodic verbal memory, and Coloured Progressive Matrices of Raven (CPMR) and Clock Drawing Test (CDT) to investigate executive functioning.
Methods: Forty subjects with amnestic MCI were recruited. All of them underwent neurological exam, neuropsychological testing and lumbar puncture at time of diagnosis. Cognition were explored by MMSE (global cognitive functioning), CPMR and CDT (executive functions), SRT and PAL (episodic verbal memory). Statistical analysis was carried out by using t-test and Spearman test for correlations.
Results: In the whole population, no significant correlation between cognitive and biological markers was observed. Considering CSF biomarker level of amiloid?, thirteen subjects showed an altered pattern and converted to AD after few months, the other subjects whit a normal profile did not convert.
MMSE show a significant difference between converters/no converters groups (26.4 versus 27.6 p=0.066). Also CDT and SRT had a significant difference between two groups (3 versus 5 p= 0.003 and 5.85 versus 8.32, p=0.03).
Conclusion: According to these results, MMSE value is lower in converters, in according to patological biomarkers profile. PAL and CDT are more specific to predict conversion from MCI to AD.

We work with a Poincare' invariant deformation of the ordinary point-wise product of fields introduced by Ardalan, Arfaei, Ghasemkhani and Sadooghi, and show that it yields, through a limiting procedure of the cutoff functions, to a regularized theory, preserving all symmetries at every stage. The new gauge symmetry yields a new Hopf algebra with deformed co-structures, which is inequivalent to the standard one.

description: The analysis of the vast storehouse of email content accumulated or produced by individual users has received relatively little attention other than for specific tasks such as spam and virus filtering. Current email analysis in standard client applications consists of keyword based matching techniques for filtering and expert driven manual exploration of email files. We have implemented a tool, called the Email Mining Toolkit (EMT) for analyzing email archives which includes a graphical display to explore relationships between users and groups of email users. The chronological flow of an email message can be analyzed by EMT. Our design goal is to embed the technology into standard email clients, such as Outlook, revealing far more information about a user's own email history than is otherwise now possible. In this paper we detail the visualization techniques implemented in EMT. We show the utility of these tools and underlying models for detecting email misuse such as viral propagation, and spam spread as examples.

This is used to show that $\mathbb{E}[ \log Z_{N,ω}]$ differs from $N$ times the free energy by an amount which is also subgaussian (i.e. $o(\sqrt{N})$), specifically $O(\sqrt{\frac{N}{\log N}}\log \log N)$.

description: A new phenomenon has developed in recent bankruptcy proceedings in which trustees are “clawing back” tuition payments made by debtor-parents on behalf of their children. Relying on Bankruptcy Code section 548, trustees are arguing that because parents have no legal obligation to pay for their child’s college tuition, they receive no “reasonably equivalent value” for such payments, thereby making such transfers fraudulent and eligible for clawback in bankruptcy. These clawbacks are increasingly troubling considering the rising cost of post-secondary education and the burden such expenses can impose on this generation’s college graduates. This Note addresses the confusion in bankruptcy courts over the proper resolution of tuition clawback cases. While some courts have allowed these clawbacks, others have invoked notions of parental and societal obligations to protect debtor parents who make tuition payments on the eve of bankruptcy. This Note explores several solutions to this problem including both amending the Bankruptcy Code and providing for an alternative reading of “reasonably equivalent value.”

It is found that the pairing with an extensive s-wave symmetry robustly dominates over other pairings at low temperature in reasonable parameter region. The pairing susceptibility, the effective pairing interaction and the $(π,0)$antiferromagnetic correlation strongly increase as the on-site Coulomb interaction increases, indicating the importance of the effect of electron-electron correlation. Our non-biased numerical results provide a unified understanding of superconducting mechanism in iron-pnictides and iron-chalcogenides and demonstrate that the superconductivity is driven by strong electron-electron correlation effects.

description: Currently, Europeans traveling abroad confront frustrations when trying to access their subscriptions to Internet streaming services such as Netflix or Amazon Prime. Often, their attempts to access a movie or show are met with a message stating something along the lines of: “We are sorry. This content is not available in your country or territory.” In the vernacular of the audiovisual industry, their content is “geo-blocked” in that nation. This is due to the fact that, under the European Union’s current regulatory framework, producers of audiovisual content finance and distribute their shows in a system based on territorial exclusivity. Territorial exclusivity entails selling exclusive broadcast rights for audiovisual content to specific broadcasters and online platforms on a territory-by-territory or country-by-country basis. However, this may all be changing soon for the European Union. In May 2015, the European Commission announced its plan for a Digital Single Market, a multifaceted proposal aiming to tear down regulatory and geo-blocking walls between the European Union’s Member States and to create a single, pan-European online market. This Note explores the potential financial and cultural implications of this DSM strategy for the film and television industries in the European Union and the United States. The benefits of a pan-European territory for audiovisual content distribution rights will be immediately clear to consumers.Cross-border portability and availability of subscriptions, movies, and shows will likely be applauded. However, this Note suggests the potential costs of such a unification effort, although less immediately evident, may be substantial. In particular, cultural diversity within the European Union and the ability of smaller nations’ audiovisual industry players to compete may suffer if the costs of production and distribution increase to a pan-European scale. Throughout the growth and development of the European Union, there has been a struggle between concerns for harmonization and unification among the Member States and concerns for the preservation of unique cultural identities and diversity. The debate over the DSM is a microcosm of this balancing act, the latest chapter of an ongoing tension to define to what lengths the EU should go in unifying its Members. The European Commission’s ultimate determination of how to enact the DSM will signal how they currently prioritize these competing considerations.

description: No abstracts are to be cited without prior reference to the author.Fish stock assessments and sound advice in most cases rely on representative samples of catches. Consequently, stock assessment and management of marine fish resources exploited by those fisheries are based on poor or scarce data. Presently, sampling at sea is often random in time and place, and not necessarily representative with respect to the fleet metier. Biological sampling in distant waters is a challenge due to logistics and high costs. The use of electronic scales onboard commercial fishing vessels opens for a new approach in data collection. In recent years electronic scales measuring individual fish weights on deck have been connected to GPS, to combine catch information with information of the fishing location, effort and individual recordings from the catch. Such data collection will meet the challenges of obtaining more representative fishery data in distant waters and provide a basis for continuous sampling throughout the fishing period contributing to increased data acquisition for use in fish stock assessments
Measuring the physical activity of older adults residing in assisted living facilities

Publisher: name: University of British Columbia
Year: 2012

description: Extensive research has shown that physical activity can protect against health problems including cardiovascular disease and osteoporosis, and may reduce the risk or delay the onset of Alzheimer’s disease and dementia in older adults. Self-report questionnaires have been valuable in assessing physical activity levels and in determining the effectiveness of activity interventions for older adults in community settings and long-term care facilities. However, little research has examined the accuracy of these questionnaires for people in assisted living facilities. This study examined the validity of the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire and the Physical Activity Scale for the Elderly (PASE) in an assisted living population. Four instruments were used to validate these questionnaires: the SF-12® Health Survey, Six-Minute Walk Test, Short Physical Performance Battery, and pedometers. This study was conducted over a period of three months. Despite significant effort, during that time only four participants completed the study. Due to this small sample size, it was only possible to examine patterns in the data; the validity of the CHAMPS and the PASE in assisted living could not be evaluated. The more important findings from this study relate to the question of feasibility of conducting research in assisted living environments. While it was possible to gather data about physical activity of assisted living residents using questionnaire and performance measures, recruitment proved to be a significant challenge. Key barriers to participant recruitment are identified as wearing a pedometer, using a walker and how walkers are perceived by assisted living residents. These barriers are discussed with respect to future research about physical activity assessment in the assisted living population.

description: In hydrodynamical modeling of heavy-ion collisions, the initial-state spatial anisotropies are translated into momentum anisotropies of the final-state particle distributions. Thus, understanding the origin of the initial-state anisotropies and their uncertainties is important before extracting specific QCD matter properties, such as viscosity, from the experimental data. In this work we review the wounded nucleon approach based on the Monte Carlo Glauber model, charting in particular the uncertainties arising from modeling of the nucleon-nucleon interactions between the colliding nucleon pairs and nucleon-nucleon correlations inside the colliding nuclei. We discuss the differences between the black disk model and a probabilistic profile function approach for the inelastic nucleon-nucleon interactions, and investigate the influence of initial-state correlations using state-of-the-art modeling of these.

description: We extend prior research on masquerade detection using UNIX commands issued by users as the audit source. Previous studies using multi-class training requires gathering data from multiple users to train specific profiles of self and non-self for each user. One-class training uses data representative of only one user. We apply one-class Naïve Bayes using both the multivariate Bernoulli model and the Multinomial model, and the one class SVM algorithm. The result shows that one-class training for this task works as well as multi-class training, with the great practical advantages of collecting much less data and more efficient training. One-class SVM using binary features performs best among the one-class training algorithms.

description: No abstracts are to be cited without prior reference to the author.The FAO Code of Conduct for Responsible Fisheries (CCRF) calls for sustainable use of aquatic ecosystems and requires that fishing be conducted with due regard for the environment. However, there is growing concern that the combined effect of failing to minimize the catch of undersized fish of target species, non-target fish species, and non-fish species is threatening the long-term sustainability of fisheries, the maintenance of biodiversity and contributing to food insecurity. The United Nations General Assembly has urged States, regional fisheries management organizations and arrangements, and other relevant international organizations to reduce or eliminate bycatch, catch by lost or abandoned gear, fish discards, and to consider the development of standards for reducing or eliminating discards, such as through the development of an international plan of action, at the 28th session of the Committee on Fisheries of the Food and Agriculture Organization of the United Nations (COFI). At COFI, FAO reported on bycatch and discards within the context of illegal, unreported, and unregulated (IUU) fishing, and reiterated the concern that in poorly managed fisheries, unreported and unregulated (i) landings of bycatch, (ii) discards, and (iii) pre-catch losses are issues of major concern. In response, Norway proposed and COFI supported the development of international guidelines on bycatch management and reduction of discards through the process of an expert consultation followed by a technical consultation. This paper reviews the rationale and process of developing international guidelines.

description: Single-molecule electronic devices provide researchers with an unprecedented ability to relate novel physical phenomena to molecular chemical structures. Typically, conjugated aromatic molecular backbones are relied upon to create electronic devices, where the aromaticity of the building blocks is used to enhance conductivity. We capitalize on the classical physical organic chemistry concept of Hückel antiaromaticity by demonstrating a single-molecule switch that exhibits low conductance in the neutral state and, upon electrochemical oxidation, reversibly switches to an antiaromatic high-conducting structure. We form single-molecule devices using the scanning tunneling microscope–based break-junction technique and observe an on/off ratio of ~70 for a thiophenylidene derivative that switches to an antiaromatic state with 6-4-6-π electrons. Through supporting nuclear magnetic resonance measurements, we show that the doubly oxidized core has antiaromatic character and we use density functional theory calculations to rationalize the origin of the high-conductance state for the oxidized single-molecule junction. Together, our work demonstrates how the concept of antiaromaticity can be exploited to create single-molecule devices that are highly conducting.
The Last Galesh Herdsman: Ethno-linguistic Materials from South Caspian Rainforests

description: This article includes part of the linguistic material we documented in 2002 from a galesh ranch in central-eastern Mazandaran. It transcribes, translates, and glosses two texts related by a patriarch on his long, eventful life: the dramatic elopement with the girl he married, his successful family life and career as a pastoral nomad, and his long resistance against the laws forcing the galesh families to evacuate the forest for good. Notwithstanding our dialectological purpose, namely documentation of the largely understudied language of Mazandaran within the long-standing tradition of Iranian philology, the article may also provide raw material for the anthropologist, sociologist, and historian, as it relays an unrecorded tradition just before its total disappearance.
Local density of states in metal - topological superconductor hybrid systems

description: We study by means of the recursive Green's function technique the local density-of-states of (finite and semi-infinite) multi-band spin-orbit coupled semiconducting nanowires in proximity to an s-wave superconductor and attached to normal-metal electrodes. When the nanowire is coupled to a normal electrode, the zero-energy peak, corresponding to the Majorana state in the topological phase, broadens with increasing transmission between the wire and the leads, eventually disappearing for ideal interfaces. Interestingly, for a finite transmission a peak is present also in the normal electrode, even though it has a smaller amplitude and broadens more rapidly with the strength of the coupling. Unpaired Majorana states can survive close to a topological phase transition even when the number of open channels (defined in the absence of superconductivity) is even. We finally study the Andreev-bound-state spectrum in superconductor-normal metal-superconductor junctions and find that in multi-band nanowires the distinction between topologically trivial and non-trivial systems based on the number of zero-energy crossings is preserved.

Fluorescence in situ hybridization

description: Cancer cells exhibit nonrandom and complex chromosome abnormalities. The role of genomic changes in cancer is well established. However, the identification of complex and cryptic chromosomal changes is beyond the resolution of conventional banding methods. The fluorescence microscopy afforded by imaging technologies, developed recently, facilitates a precise identification of these chromosome alterations in cancer. The three most commonly utilized molecular cytogenetics methods comparative genomic hybridization, spectral karyotype, and fluorescence in situ hybridization, that have already become benchmark tools in cancer cytogenetics, are described in this chapter. Comparative genomic hybridization is a powerful tool for screening copy-number changes in tumor genomes without the need for preparation of metaphases from tumor cells. Multicolor spectral karyotype permits visualization of all chromosomes in one experiment permitting identification of precise chromosomal changes on metaphases derived from tumor cells. The uses of fluorescence in situ hybridization are diverse, including mapping of alteration in single copy genes, chromosomal regions, or entire chromosomes. The opportunities to detect genetic alterations in cancer cells continue to evolve with the use of these methodologies both in diagnosis and research.
U(n) Spectral Covers from Decomposition

description: We construct decomposed spectral covers for bundles on elliptically fibered Calabi-Yau threefolds whose structure groups are S(U(1) x U(4)), S(U(2) x U(3)) and S(U(1) x U(1) x U(3)) in heterotic string compactifications. The decomposition requires not only the tuning of the SU(5) spectral covers but also the tuning of the complex structure moduli of the Calabi-Yau threefolds. This configuration is translated to geometric data on F-theory side. We find that the monodromy locus for two-cycles in K3 fibered Calabi-Yau fourfolds in a stable degeneration limit is globally factorized with squared factors under the decomposition conditions. This signals that the monodromy group is reduced and there is a U(1) symmetry in a low energy effective field theory. To support that, we explicitly check the reduction of a monodromy group in an appreciable region of the moduli space for an $E_6$ gauge theory with (1+2) decomposition. This may provide a systematic way for constructing F-theory models with U(1) symmetries.

description: We introduce the Email Mining Toolkit (EMT), a system that implements behavior-based methods to improve security of email systems. Behavior models of email flows and email account usage may be used for a variety of detection tasks. Behavior-based models are quite different from "content-based" models in common use today, such as virus scanners. We evaluate the soundness of these techniques for the detection of the onset of viral propagations. The results achieved for the detection of the onset of viral propagations suggest email delivery should be egress rate limited - stored for a while and then forwarded - or a record of recently delivered emails should be kept in order to develop sufficient statistics to verify a propagation is ongoing. EMT can form part of a larger security platform that deals with email security issues in general. We present the variety of EMT models implemented to date and suggest other security tasks that may benefit for its detection capabilities.
