description: The IP security protocols are sufficiently mature to benefit from multiple independent implementations and worldwide deployment. Towards that goal, we implemented the protocols for the BSD/OS, Linux, OpenBSD and NetBSD. While some differences in the implementations exist due to the differences in the underlying operating system structures, the design philosophy is common. A radix tree, namely the one used by the BSD code for routing purposes, is used to implement the policy engine; a transform table switch is used to make addition of security transformations an easy process; a lightweight kernel-user communication mechanism is used to pass key material and other configuration information from user space to kernel space, and to report asynchronous events such as requests for new keys from the kernel space to a user-level keying daemon; and two distinct ways of intercepting outgoing packets and applying the IPsec transformations to them are employed. The techniques used in our implementations are explained, differences in approaches are analysed, and hints are given to potential future implementers of new transforms.

description: Dijet anomaly reported by the CDF (Collider Detector at Fermilab) collaboration in 1.96 TeV p-pbar collisions is investigated within the standard model by considering effects of parton distribution functions on various processes: W+dijet, Z+dijet, WW, ZW, and top production. Since the anomalous peak exists in the dijet-mass region of 140 GeV with the p-pbar center-of-mass energy sqrt{s}=1.96 TeV, a relevant momentum fraction x of partons is roughly 0.1. In this x region, recent HERMES semi-inclusive charged-lepton scattering experiment indicated that the strange-quark distribution could be very different from a conventional one, which has been used for many years, based on opposite-sign dimuon measurements in neutrino-induced deep inelastic scattering. We investigated effects of such variations in the strange-quark distribution s(x) on the anomaly. We found that distributions of W+dijets and other process are affected by the strange-quark modifications in wide dijet-mass regions including the 140 GeV one. Since the CDF anomaly was observed in the shoulder region of the dijet-mass distribution, a slight modification of the distribution shape could explain at least partially the CDF excess. Therefore, it is important to consider such effects within the standard model for judging whether the CDF anomaly indicates new physics beyond the standard model. We also show modification effects of the strange-quark distribution in the LHC (Large Hadron Collider) kinematics, where cross sections are sensitive to a smaller-x region of s(x).

description: Measurements of the Higgs-boson production cross section at the LHC are an important tool for studying electroweak symmetry breaking at the quantum level, since the main production mechanism gg-->h is loop-suppressed in the Standard Model (SM). Higgs production in extra-dimensional extensions of the SM is sensitive to the Kaluza-Klein (KK) excitations of the quarks, which can be exchanged as virtual particles in the loop. In the context of the minimal Randall-Sundrum (RS) model with bulk fields and a brane-localized Higgs sector, we derive closed analytical expressions for the gluon-gluon fusion process, finding that the effect of the infinite tower of virtual KK states can be described in terms of a simple function of the fundamental (5D) Yukawa matrices. Given a specific RS model, this will allow one to easily constrain the parameter space, once a Higgs signal has been established. We explain that discrepancies between existing calculations of Higgs production in RS models are related to the non-commutativity of two limits: taking the number of KK states to infinity and removing the regulator on the Higgs-boson profile, which is required in an intermediate step to make the relevant overlap integrals well defined. Even though the one-loop gg-->h amplitude is finite in RS scenarios with a brane-localized Higgs sector, it is important to introduce a consistent ultraviolet regulator in order to obtain the correct result.

description: In a hard real-time embedded system, the time at which a result is computed is as important as the result itself. Modern processors go to extreme lengths to ensure their function is predictable, but have abandoned predictable timing in favor of average-case performance. Real-time operating systems provide timing-aware scheduling policies, but without precise worst-case execution time bounds they cannot provide guarantees. We describe an alternative in this paper: a SPARC-based processor with predictable timing and instruction-set extensions that provide precise timing control. Its pipeline executes multiple, independent hardware threads to avoid costly, unpredictable bypassing, and its exposed memory hierarchy provides predictable latency. We demonstrate the effectiveness of this precision-timed (PRET) architecture through example applications running in simulation.

description: In this note, we study the coupling of the techni-dilaton to the weak bosons. We consider two cases: (1) The dilaton directly couples to the weak bosons similarly to the SM. (2) The coupling in question is effectively induced only through the techni-fermion loops. In both cases, we find that the coupling is essentially determined by the mass-squared of the weak bosons over the dilaton decay constant.

Detection and characterization of human mammary stem cells
Creators: name: Eirew, Peter
Publisher: name: University of British Columbia
Year: 2011

description: The mammary gland of adult female mice contains undifferentiated epithelial stem cells with in vivo regenerative and self-renewal properties. A biologically similar population likely exists in the human breast but a specific and quantitative methodology to identify and characterize these cells has been lacking. In this study I show that human mammary structures are reproducibly generated when dissociated suspensions of primary human mammary cells are propagated in collagen gels that have been implanted under the renal capsule of highly immunodeficient, hormone-treated mice. These structures contain differentiated cells of both mammary lineages in a spatial organization similar to normal mammary tissue, and display functional maturation into milk-producing glands when the hosts become pregnant. In vitro assays of single cell suspensions prepared from these regenerated glands revealed the consistent presence of mammary progenitor cells able to form adherent bi-lineage as well as pure luminal and myoepithelial colonies. In addition, when these cells are suspended in new gels and transplanted into secondary immunodeficient mice, similar progenitor-containing structures are demonstrable, indicative of a regenerative process that recreates the normal developmental hierarchy. This daughter progenitor production endpoint allows the frequency of these self-renewing human mammary stem cells to be derived from limiting dilution transplant assays as 1 per 10³–10⁴ cells in normal adult human reduction mammoplasty samples, and their phenotype to be established as CD49f⁺EpCAM⁻⁄low CD31⁻CD45⁻. I have also developed methodologies to isolate fractions of cells from mammoplasty tissue that are enriched in cells in different phases of the cell cycle (G0/G1/S/G2/M). Application of functional assays to these fractions indicates that a proportion of stem and progenitor cells in normal adult breast tissue exhibit phenotypes that are associated with actively proliferating cells. These studies support a model of mammary cell production that includes a significant rate of normal turnover of primitive cells, and sets the stage for further work to identify the factors and molecular interactions that regulate this process.

description: In Parkinson's disease (PD), concurrent declines in cognitive and motor domain function can severely limit an individual's ability to conduct daily tasks. Current diagnostic methods, however, lack precision in differentiating domain-specific contributions of cognitive or motor impairments based on a patients' clinical manifestation. Fear of falling (FOF) is a common clinical manifestation among the elderly, in which both cognitive and motor impairments can lead to significant barriers to a patients' physical and social activities. The present study evaluated whether a set of analytical and machine-learning approaches could be used to help delineate boundary conditions and separate cognitive and motor contributions to a patient's own perception of self-efficacy and FOF. Cognitive and motor clinical scores, in conjunction with FOF, were collected from 57 Parkinson's patients during a multi-centre rehabilitation intervention trial. Statistical methodology was used to extract a subset of uncorrelated cognitive and motor components associated with cognitive and motor predictors, which were then used to independently identify and visualize cognitive and motor dimensions associated with FOF. We found that a central cognitive process, extracted from tests of executive, attentional, and visuoperceptive function, was a unique and significant independent cognitive predictor of FOF in PD. In addition, we provide evidence that the approaches described here may be used to computationally discern specific types of FOF based on separable cognitive or motor models. Our results are consistent with a contemporary model that the deterioration of a central cognitive mechanism that modulates self-efficacy also plays a critical role in FOF in PD.

description: We systematically investigate the magnetic and electronic properties of graphene adsorbed with diluted 3d-transition and noble metal atoms using first principles calculation methods. We find that most transition metal atoms (i.e. Sc, Ti, V, Mn, Fe) favor the hollow adsorption site, and the interaction between magnetic adatoms and π-orbital of graphene induces sizable exchange field and Rashba spin-orbit coupling, which together open a nontrivial bulk gap near the Dirac points leading to the quantum-anomalous Hall effect. We also find that the noble metal atoms (i.e. Cu, Ag, Au) prefer the top adsorption site, and the dominant inequality of the AB sublattice potential opens another kind of nontrivial bulk gap exhibiting the quantum-valley Hall effect.

description: A space $Y$ is called an {\em extension} of a space $X$ if $Y$ contains $X$ as a dense subspace. Two extensions of $X$ are said to be {\em equivalent} if there is a homeomorphism between them which fixes $X$ point-wise. For two (equivalence classes of) extensions $Y$ and $Y'$ of $X$ let $Y\leq Y'$ if there is a continuous function of $Y'$ into $Y$ which fixes $X$ point-wise. An extension $Y$ of $X$ is called a {\em one-point extension} of $X$ if $Y\backslash X$ is a singleton. Let ${\mathcal P}$ be a topological property. An extension $Y$ of $X$ is called a {\em ${\mathcal P}$-extension} of $X$ if it has ${\mathcal P}$. One-point ${\mathcal P}$-extensions comprise the subject matter of this article. Here ${\mathcal P}$ is subject to some mild requirements. We define an anti-order-isomorphism between the set of one-point Tychonoff extensions of a (Tychonoff) space $X$ (partially ordered by $\leq$) and the set of compact non-empty subsets of its outgrowth $βX\backslash X$ (partially ordered by $\subseteq$). This enables us to study the order-structure of various sets of one-point extensions of the space $X$ by relating them to the topologies of certain subspaces of its outgrowth. We conclude the article with the following conjecture. For a Tychonoff spaces $X$ denote by ${\mathscr U}(X)$ the set of all zero-sets of $βX$ which miss $X$. \noindent{\bf Conjecture.} {\em For locally compact spaces $X$ and $Y$ the partially ordered sets $({\mathscr U}(X),\subseteq)$ and $({\mathscr U}(Y),\subseteq)$ are order-isomorphic if and only if the spaces ${\em cl}_{βX}(βX\backslash\upsilon X)$ and ${\em cl}_{βY}(βY\backslash\upsilon Y)$ are homeomorphic.}

Then, we define the linear and quadratic simplicity constraints which reduce the spinor variables to (framed) 3d spacelike polyhedra embedded in Minkowski spacetime.

description:
Purpose Recent research suggests the determinants of and links between psychological distress and psychiatric disorder are distinct among Black Americans. Yet, these associations have not been explored among Black women, despite the unique social experiences, risks, and mental health patterns they face. The present study assessed the sociodemographic and psychosocial determinants of distress and disorder and evaluated the distress–disorder association, including whether it was conditional on sociodemographic and psychosocial characteristics among Black women. Methods Data were from 328 Black women in the Nashville Stress and Health Study, a cross-sectional community epidemiologic survey of Blacks and Whites in Nashville, Tennessee, and was used to assess the correlates of distress (CES-D depressive symptoms scale) and major depressive disorder (MDD; based on the CIDI). Multinomial logistic regression models estimated the extent to which greater distress was associated with higher risk of “chronic” or “resolved MDD”. Results Stress exposure and marital status were associated with greater distress, while stress exposure and childhood SES were associated with elevated disorder risk. Although increased distress was associated with greater disorder risk, significant interactions indicated these associations depend on differences in age and adult socioeconomic status within this population. Conclusions This study identifies distinct correlates of distress and disorder and shows that the distress–disorder association varies among subgroups of Black women. Results have important implications for public health research and practice, as they highlight the factors that matter most for the mental health outcomes of Black women.

description: Buckminsterfullerene (C60) was recently confirmed to be the largest molecule identified in space. However, it remains unclear how, and where this molecule is formed. It is generally believed that C60 is formed from the build up of small carbonaceous compounds, in the hot and dense envelopes of evolved stars. Analyzing infrared observations, obtained by Spitzer and Herschel, we found that C60 is efficiently formed in the tenuous and cold environment of an interstellar cloud illuminated by strong ultraviolet (UV) radiation fields. This implies that another formation pathway, efficient at low densities, must exist. Based on recent laboratory and theoretical studies, we argue that Polycyclic Aromatic Hydrocarbons are converted into graphene, and subsequently C60, under UV irradiation from massive stars. This shows that alternative - top-down - routes are key to understanding the organic inventory in space.

Clap Detection and Discrimination for Rhythm Therapy

Subjects: Electrical engineering

description: An auditory training system relies on determining how well individual users can clap their hands together 'in time' with a prompt. Because the system is intended for a scenario in which an entire class of students is simultaneously engaged in this training, each system must distinguish between the claps of a single user and background claps from other nearby users. Available cues for this discrimination include the absolute energy of the clap sound, its source azimuth (estimated from stereo microphones), and its range as conveyed by the direct-to-reverberant energy balance. We present a set of features to capture these cues, and report our results on detecting and distinguishing 'near-field' and 'far-field' claps in a corpus of 1650 claps recorded in realistic classroom environments. When room and location are matched between training and test data, the classification error rate falls as low as 0.13%; when training data is recorded from a separate room, the error rate is still below 4.8% in the worst case.

An important step in the authors' algorithm for finding viewpoints is the computation of the volumes swept by polyhedral objects moving through space. A method for approximating these volumes for arbitrarily moving polyhedra is presented. Some swept volume results are presented and methods for integrating these results into the authors' automated machine vision planning (MVP) system are discussed.

description: We theoretically analyze the temperature behavior of paraxial light in thermal equilibrium with a dye-filled optical microcavity. At low temperatures the photon gas undergoes Bose-Einstein condensation (BEC), and the photon number in the cavity ground state becomes macroscopic with respect to the total photon number. Owing to a grandcanonical excitation exchange between the photon gas and the dye molecule reservoir, a regime with unusually large fluctuations of the condensate number is predicted for this system that is not observed in present atomic physics BEC experiments.

"The centre is everywhere" : Nietzsche's overcoming of modernity through musical dissonance
Creators: name: Polakoff, Gregory Ivan
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation argues that musical dissonance is a master metaphor in the works of Friedrich Nietzsche. In The Birth of Tragedy, Nietzsche claims that musical dissonance constitutes the “foundations of all existence.” I contend that it forms the foundation of a radical, life-affirming, and dynamic epistemology. Musical dissonance provides Nietzsche with the means to “overcome” the ascetic, life-denying, metaphysical philosophies that he believes have enervated and depleted Western civilization since the advent of Platonic and Judeo-Christian thought. An analysis of Nietzsche’s major works through the lens of musical dissonance reveals that it constitutes a powerful extended metaphor throughout his writings, and inspires his understanding of tragedy, science, eternal recurrence, the Übermensch, the will to power, Bildung, and other concepts. The theoretical approach taken is informed by Arnold Schoenberg’s concept of the “emancipation of the dissonance,” which he claims to be the guiding principle of his twelve-tone system of musical composition. Nietzsche “emancipates” dissonance from the constrictions of metaphysical philosophies––a category that includes modern science in Nietzsche’s outlook––in order to facilitate a complete “revaluation of all values,” a project that Nietzsche outlines in his late works, which I contend involves the continual rethinking of all values with respect to a musical, dissonant epistemology. Musical, dissonant thinking does not rely upon a central authority for deriving truth and meaning, but rather a dynamic and pluralistic method of understanding that is without a unitary, fixed centre. This study demonstrates how Nietzsche’s fascination with musical dissonance in his early texts inspired the “revaluation of all values”––an act that represents the overcoming of modernity––through a close reading of The Birth of Tragedy, The Gay Science, Thus Spoke Zarathustra, and Ecce Homo. Gilles Deleuze, Claude Lévesque, Sarah Kofman, and Bruce Benson are among the other key thinkers whose works inspire the framework for my analysis. The concluding section explores the far-reaching implications of Nietzsche’s musical, dissonant philosophy and aesthetics in the twentieth century through an exploration of its legacy in the writings of Thomas Mann, Theodor Adorno, and Arnold Schoenberg
Voice over IP: Risks, Threats and Vulnerabilities
Creators: name: Keromytis, Angelos D.
Publisher: name: Columbia University
Year: 2009
Subjects: Computer science

description: Voice over IP (VoIP) and Internet Multimedia Subsystem (IMS) technologies are rapidly being adopted by consumers, enterprises, governments and militaries. These technologies offer higher flexibility and more features than traditional telephony (PSTN) infrastructures, as well as the potential for lower cost through equipment consolidation and, for the consumer market, new business models. However, VoIP/IMS systems also represent a higher complexity in terms of architecture, protocols and implementation, with a corresponding increase in the potential for misuse. Here, we begin to examine the current state of affairs on VoIP/IMS security through a survey of known/disclosed security vulnerabilities in bug-tracking databases. This paper should serve as a starting point for understanding the threats and risks in a rapidly evolving set of technologies that are seeing increasing deployment and use. Our goal is to gain a better understanding of the security landscape with respect to VoIP/IMS, toward directing future research in this and other similar emerging technologies.

Search for the Higgs boson in the H->WW->lvjj decay channel in pp collisions at sqrt{s} = 7 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for a Higgs boson has been performed in the H->WW->lvjj channel in 1.04/fb of pp collision data sqrt{s} = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No significant excess of events is observed over the expected background and limits on the Higgs boson production cross section are derived for a Higgs boson mass in the range 240 GeV < mH < 600 GeV. The best sensitivity is reached for mH = 400 GeV, where the 95% confidence level upper bound on the cross section for H->WW production is 3.1 pb, or 2.7 times the Standard Model prediction.

Is John Henryism a Health Risk or Resource?: Exploring the Role of Culturally Relevant Coping for Physical and Mental Health among Black Americans
Creators: name: Thomas Tobin C.S.
name: Robinson M.N.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description:
Research shows that John Henryism, a high-effort, active coping style, is associated with poor physical health, whereas others suggest it may be psychologically beneficial. As such, it is unclear whether John Henryism represents a health risk or resource for black Americans and whether its impact varies across sociodemographic and gender groups. The present study used data from a representative community sample of black Americans (n = 627) from the Nashville Stress and Health Study (2011–2014) to clarify the physical and mental health consequences of John Henryism by assessing its relationship with depressive symptoms and allostatic load (AL). Results indicate that John Henryism is associated with increased AL scores and fewer depressive symptoms. Additionally, the association between John Henryism and AL is conditional on socioeconomic status. Study results underscore the importance of evaluating both physical and mental health to clarify the health significance of John Henryism among black Americans.
Dependence of the GRB Lag-Luminosity Relation on Redshift in the Source Frame

description: The lag-luminosity relation for gamma-ray bursts (GRBs) is an anti-correlation between the time lag, tau_lag, which represents the delay between the arrival of hard and soft photons, and the isotropic peak luminosity, L. In this paper, we use a sample of 43 Swift bursts to investigate whether this relation depends on redshift. Both the z-correction and the k-correction are taken into account. Our analysis consists of binning the data in redshift, z, then applying a fit of the form: log(L) = A + Blog(tau_lag0/) for each bin, where tau_lag0 is the time-lag in the burst's source frame, and is the corresponding mean value for the entire sample. The goal is to see whether the two fitting parameters, A and B, evolve in a systematic way with z. Our results indicate that both the normalization, A, and the slope, B, seem to vary in a systematic way with redshift. We note that although good best-fits were obtained, with reasonable values for both the linear regression coefficient, r, and the reduced chi-squared, the data showed large scatter. Also, the number of GRBs in the sample studied is not large, and thus our conclusions are only tentative at this point. A flat universe with omega_M = 0.27, omega_lambda = 0.73, and a Hubble constant, H_0 = 70 km s-1 Mpc-1 is assumed.
