description: Finite metric spaces arise in many different contexts. Enormous bodies of data, scientific, commercial and others can often be viewed as large metric spaces. It turns out that the metric of graphs reveals a lot of interesting information. Metric spaces also come up in many recent advances in the theory of algorithms. Finally, finite submetrics of classical geometric objects such as normed spaces or manifolds reflect many important properties of the underlying structure. In this paper we review some of the recent advances in this area.

description: We consider the pre-test estimation of . the parameters of a linear regression model after a preliminary-test for exact linear restrictions when the model is mis-specified through the omission of relevant regressors and the usual assumption of normal regression disturbances is widened to a subclass of the family of spherically symmetric errors. We derive and analyse the exact risk (under quadratic loss) of a pre-test estimator of the prediction vector and of the scale parameter.

Induction of neuronal apoptosis inhibitory protein expression in response to androgen deprivation by NF-κB in prostate cancer cells
Creators: name: Chiu, Helen Hoi-Lun
Publisher: name: University of British Columbia
Year: 2011

description: Androgen deprivation therapy is an efficacious treatment for advanced prostate cancer (CaP) by inducing apoptosis of prostate cells. Despite the initial effectiveness of this systemic therapy, the cancer will inevitably recur and progress to an androgen-independent stage. The molecular mechanism by which some CaP cells may bypass the cell death induced by androgen deprivation is unclear. Emerging studies have highlighted the role of the inhibitor of apoptosis protein (lAP) family members in conferring an enhanced ability of malignant cells to survive in conditions normally resulting in cell death. Therefore, we explored levels of expression of these anti-apoptotic proteins in CaP cells in response to androgen deprivation. Levels of neuronal apoptosis inhibitory protein (NAIP) mRNA were significantly increased in response to castration of hosts. The increase in NAIP mRNA levels in response to androgen deprivation was further confirmed in an in vitro system. Nuclear factor (NF)-κB, for which constitutive activity has been implicated in CaP, is suspected to play a role in the expression of lAPs. Using a NF-κB luciferase reporter construct, we demonstrated that the transcriptional activity of NF-κB was inhibited by androgen. In vitro, nuclear localization of NF-κB correlated with the DNA-binding activity of NF-κB as determined by electrophoretic mobility shift assay in human CaP cell lines with different androgen requirement and androgen receptor status. However, in vivo, the DNA-binding activity of NF-κB was independent from its protein levels in the nucleus. Importantly, elevated expression of NAIP correlated to the increased DNA-binding activity of NF-κB in vivo in response to castration of the hosts. To determine if the transcription of NAIP was directly regulated by NF-κB, subsequent characterization of three κB-like sites in the regulatory regions of the NAIP locus led us to confirm the physiological relevance of the κB-like site within the second intron of the gene locus using chromatin immunoprecipitation assay. Our observations suggest that transcription of NAIP may be regulated by NF-κB via regulatory element(s) in the NAIP locus in response to androgen deprivation. Thus, this study underlines a plausible mechanism by which some CaP cells may acquire the ability to resist apoptosis in androgen-deprived conditions.
Non-exotic theory of 1/f noise as a trace of infralow-frequency fluctuations

description: This report is aimed at reviving the explanation of flicker-noise observations as the result of spectral measurement of very low-frequency but stationary narrow-band fluctuations named as infralow-frequency noise (ILF noise) [A. Ya. Shul'man. Sov. Tech. Phys. Lett. 7, 337 (1981), Sov. Phys. JETP 54, 420 (1981)]. Such a kind of the spectrum analyzer output takes place when the ILF-noise correlation time is much longer than the analyzer reciprocal bandwidth. This result is valid for both analog and digital spectral measurements. The measured signal is proportional in this case to the mean square and not to the spectral density of the noise. The equilibrium temperature fluctuations and the defect-motion as mechanisms of $1/f$ noise in metal films are reconsidered from this point of view. It is shown that the ILF-noise approach allows to remove the main objection against temperature fluctuation model and difficulties within the defect-motion model widely discussed in literature.

description: In the present work, we report a cultivation of probiotic strains of Lactobacillus plantarum S26, Lb. brevis S27 and Lb. sakei S16 in media supplemented with 1% of glucooligosacharides (GOSs) synthesized by glucansucrases from fructophilic lactic acid bacteria Lb. pentosus AG8, Lb. kunkeei AG9, AG10 and AG11. GOSs fractions synthesized at maltose/sucrose ratios 0.5 and 1 were chosen for the utilization experiments, determination of specific growth rates (µ) of the probiotic strains and acidification of the media. For the three probiotic lactobacilli were calculated very close µ values to these ones on glucose media. On the other hand, the observed growth of the strains in the GOSs supplemented media showed strain-specific profile. Lb. sakei S16 showed on average 39% lower µ than these ones of Lb. plantarum S26, Lb. brevis S27 independently of the carbohydrate source. The calculated µ values correlated well with the heterofermentative metabolism of the probiotic lactobacilli which is associated with production of lactic, acetic acid and very little of ethanol. At 48 h of the anaerobic cultivation of the strains, strain-specific ratios of the produced lactate to acetate were determined. In case of Lb. plantarum S26 the ratio is 4.1, and for Lb. brevis S27 and Lb. sakei S16 – 1.4 and 0.8, respectively. It seems that the decrease of lactate production at expense of acetate one is associated with the specific metabolism of the given stain and is not directly related to the composition of GOSs preparations tested. In all the cases, the ability of the tested GOSs preparations to support the growth and acids production of the probiotic lactobacilli is a promising sign for their potency as prebiotics.

description: Inspired by recent claims for a varying fine structure constant, alpha, we investigate the effect of ``promoting coupling constants to variables'' upon various parameters of the standard model. We first consider a toy model: Proca's theory of the massive photon. We then explore the electroweak theory with one and two dilaton fields. We find that a varying alpha unavoidably implies varying W and Z masses. This follows from gauge invariance, and is to be contrasted with Proca' theory. For the two dilaton theory the Weinberg angle is also variable, but Fermi's constant and the tree level fermion masses remain constant unless the Higgs' potential becomes dynamical. We outline some cosmological implications.

description: We study size and growth distributions of products and business firms in the context of a given industry. Firm size growth is analyzed in terms of two basic mechanisms, i.e. the increase of the number of new elementary business units and their size growth. We find a power-law relationship between size and the variance of growth rates for both firms and products, with an exponent between -0.17 and -0.15, with a remarkable stability upon aggregation. We then introduce a simple and general model of proportional growth for both the number of firm independent constituent units and their size, which conveys a good representation of the empirical evidences. This general and plausible generative process can account for the observed scaling in a wide variety of economic and industrial systems. Our findings contribute to shed light on the mechanisms that sustain economic growth in terms of the relationships between the size of economic entities and the number and size distribution of their elementary components.

description: Magnetic hopfions are topologically protected three-dimensional solitons that are constituted by a tube which exhibits a topologically nontrivial spin texture in the cross-section profile and is closed to a torus. Here we show that the hopfion's locally uncompensated emergent field leads to a topological Hall signature, although the topological Hall effect vanishes on the global level. The topological Hall signature is switchable by magnetic fields or electric currents and occurs independently of the anomalous and conventional Hall effects. It can therefore be exploited to electrically detect hopfions in experiments and even to distinguish them from other textures like skyrmion tubes. Furthermore, it can potentially be utilized in spintronic devices. Exemplarily, we propose a hopfion-based racetrack data storage device and simulate the electrical detection of the hopfions as carriers of information.

description: Most of the fractions observed to date belong to the sequences $ν=n/(2pn\pm 1)$ and $ν=1-n/(2pn\pm 1)$, $n$ and $p$ integers, understood as the familiar {\em integral} quantum Hall effect of composite fermions. These sequences fail to accommodate, however, many fractions such as $ν=4/11$ and 5/13, discovered recently in ultra-high mobility samples at very low temperatures. We show that these "next generation" fractional quantum Hall states are accurately described as the {\em fractional} quantum Hall effect of composite fermions.

description: This paper considers the effect of heteroscedastic regression errors on the size of the Chow test for structural stability. We show that bounds can be placed on the true size of this test in the light of such misspecification, and on the true critical value needed to achieve any desired significance level when using the test under various degrees of heteroscedasticity. These bounds are data-independent, and some cases are tabulated. An example is given to illustrate the practical application of the critical value bounds.

description: How much performance do VM instruction-pointer (IP) updates cost and how much benefit do we get from optimizing them away? Two decades ago it had little effect on the hardware of the day, but on recent hardware the dependence chain of IP updates can become the critical path on processors with out-of-order execution. In particular, this happens if the VM instructions are light-weight and the application programs are loop-dominated. The present work presents several ways of reducing or eliminating the dependence chains from IP updates, either by breaking the dependence chains with the loop optimization or by reducing the number of IP updates (the c and ci optimizations) or their latency (the b optimization). Some benchmarks see speedups from these optimizations by factors $>2$ on most recent cores, while other benchmarks and older cores see more modest results, often in the speedup ranges 1.1--1.3.

description: This paper considers the choice of critical value for a pre-test of exact linear restrictions when estimating the regression error variance. We calculate the critical value according to a mini-max risk regret criterion and compare the resulting risk functions with those generated by using the critical value which minimises the pre-test risk function. The results suggest that the latter approach is generally preferable.

description: We report the first time-resolved photometric and spectroscopic optical observations of the X-ray source RX J2133.7+5107, identified in the ROSAT survey. A clear persistent optical light pulsation is discovered with fast photometry at a period of P_{omega} =(570.823 +/-0.013) s which we associate with the spin period of an accreting white dwarf. Radial velocity curves of the strong emission lines show modulation with a period of P_{Omega} =(7.193 +/- 0.016) hr, identified as the orbital period. These observations establish that the source is a member of the intermediate polar class (IPs) of magnetic cataclysmic variables. With only 4 IPs with longer orbital periods, RX J2133.7+5107 is among the widest systems. It is a unique IP with an orbital period in the middle of the so-called (6-10)hr IP gap and it shows a significant degree of asynchronism with a ratio P_{omega}/P_{Omega} of 0.02. When attributed to the motion of the white dwarf, the emission lines orbital modulation yields a mass function of f_m = (1.05 +/- 0.21) 10^{-2} Msun which, for a probable inclination i < 45 deg and a white dwarf mass M_{wd} = (0.6-1.0) Msun, corresponds to a secondary mass M_{s} > (0.27-0.37) Msun.

description: Various studies have considered the risk properties under Quadratic loss, of estimators of the scale parameter after a preliminary test for exact linear restrictions on the regression coefficients. This loss function is symmetric though, arguably, under-estimation of the scale has greater consequences than over-estimation. In this paper we consider the LINEX loss function, which allows for an asymmetric penalty. We derive the exact risk of estimators of the error variance after a pre-test of exact restrictions and we numerically evaluate the derived expressions. The results are compared with those under quadratic loss so that the effects of the asymmetry can be ascertained.

description: Comprehensive understanding of particle motion in microfluidic devices is essential to unlock novel technologies for shape-based separation and sorting of microparticles like microplastics, cells and crystal polymorphs. Such particles interact hydrodynamically with confining surfaces, thus altering their trajectories. These hydrodynamic interactions are shape-dependent and can be tuned to guide a particle along a specific path. We produce strongly confined particles with various shapes in a shallow microfluidic channel via stop flow lithography. Regardless of their exact shape, particles with a single mirror plane have identical modes of motion: in-plane rotation and cross-stream translation along a bell-shaped path. Each mode has a characteristic time, determined by particle geometry. Furthermore, each particle trajectory can be scaled by its respective characteristic times onto two master curves. We propose minimalistic relations linking these timescales to particle shape. Together these master curves yield a trajectory universal to particles with a single mirror plane.

Video and social justice : reimagining the city
Creators: name: Hallenbeck, Jessica Wynne
Publisher: name: University of British Columbia
Year: 2011

description: There is presently an impressive body of literature on the relationship between video and empowerment, but there is scant attention paid to the larger concept of social justice, and in what ways video may assist in expressing and advancing claims to the city. This thesis explores some possible ways that video can contribute to the struggle for social justice. Using one short video, Wishlist, as a case study, the research probes the relationship between the right to the city, social justice, and video. Drawing on definitions of social justice advanced by Henri Lefebvre and Iris Marion Young, this thesis argues that the right to the city begins with imagining cities as being different from their present state. This imagining involves dialoguing, participating, and appropriating. Video is one creative tool that can assist in this imagining.

description: The study selected 10 non-EU countries for which data concerning the level of support for agriculture were available. The time range covered the years 1995-2011, while the main sources of data were tables prepared as part of the World Input-Output Database. The conducted analysis confirmed the paradox of development of agriculture, according to which the high potential of the agricultural sector is associated with a relatively low macroeconomic efficiency and at the same time high productivity. The article sets a level of self-sufficiency in the agricultural sector in the studied countries as well as international trade relations with foreign countries. In addition, it noted the process of equalizing the level of support for agriculture in different countries, while maintaining a relatively high diversity. / Synopsis. Głównym celem artykułu było zbadanie współzależności międzygałęziowych w odniesieniu do rolnictwa przy pomocy modeli input-output w wybranych krajach w kontekście poziomu wsparcia finansowego rolnictwa w tych państwach.

Zakres czasowy obejmował lata 1995-2011, natomiast głównym źródłem danych były tablice przygotowane w ramach projektu World Input-Output Database. Przeprowadzone analizy potwierdziły paradoks rozwojowy rolnictwa, zgodnie z którym wysoki potencjał sektora rolnego wiąże się z relatywnie niską efektywnością makroekonomiczną i jednocześnie wysoką wydajnością pracy. W artykule określono też poziom samowystarczalności sektora rolnego w badanych krajach oraz związki rolnictwa z zagranicą. Dodatkowo wskazano na proces wyrównywania się poziomu wsparcia dla rolnictwa w poszczególnych krajach, przy utrzymaniu relatywnie wysokiego zróżnicowania.

description: Vitrimers are a special class of polymers that undergo dynamic cross-linking under thermal stimuli. Their ability to exchange covalent bonds can be harnessed to mitigate damage in a composite or to achieve recyclable aerospace composites. This work addresses the primary challenge of modeling dynamic cross-linking reactions in vitrimers during thermomechanical loading. Dynamic bond exchange reaction probability change during heating and its effect on dilatometric and mechanical response are simulated for the first time in large scale molecular dynamics simulations. Healing of damage under thermal cycling is computed with mechanical properties predicted before and after self--healing.

description: The main aim of the article is to present multidimensional assessment of the financial condition of food sector production in Poland and Germany by size of enterprises. Comparative study was based on European Central Bank’s database that allows assessment of different economic sectors in five different areas: financial structure, financial liquidity, indebtedness, activity and profitability. The research proved that Polish enterprises (compared to German enterprises) apply more conservative financial strategies, experience better financial liquidity, are betted adapted to debt service, less productively use their assets, obtain higher sale markups and are comparable to German return rates from own capital. / Synopsis. Głównym celem artykułu była wielowymiarowa ocena kondycji finansowej sektora produkcji artykułów spożywczych w Polsce i Niemczech w układzie klas wielkości przedsiębiorstw. Badania porównawcze przeprowadzono na podstawie bazy danych Europejskiego Banku Centralnego, która umożliwia ocenę różnych sektorów gospodarki w pięciu obszarach: struktury finansowej, płynności finansowej, zadłużenia, aktywności oraz rentowności. Badania wykazały, że przedsiębiorstwa w Polsce – w stosunku do przedsiębiorstw w Niemczech - stosują bardziej konserwatywne strategie finansowe, mają lepszą płynność finansową, posiadają większą zdolność do obsługi długu, mniej produktywnie wykorzystują posiadany majątek, uzyskują wyższą marżę na sprzedaży oraz porównywalną z firmami niemieckimi stopę zwrotu z kapitału własnego.
title: Content and organizational differences between autobiographical and semantic memories
Creators: name: Conway, Martin
Publisher: name: The Open University
Year: 1984

description: This thesis investigated differences between semantic and autobiographical memories of the same item. In a review of the problem area [Part 1] it was shown that the semantic/episodic distinction, SED, [Tulving 1972, 1983] had not been unequivocally supported by research and was open to a number of theoretical criticisms. A revised version of SED focusing on content and organizational differences [as opposed to process differences between the two classes of memory was shown to be less vunerable to theoretical criticism, to accomodate past findings more fully, and to suggest ways in which the two distinguished. classes of memory might be The revised version of SED more markedly emphasised the autobiographical content of episodic memories and suggested ways in which the two classes of memory may be related. A series of experiments are reported (Part 2] which investigated the hypotheses that autobiographical and semantic memories of the same items differed in terms of the information that they represented, were differently organized, and were indirectly connected. A number of experimental techniques were employed including free descriptions, priming, property verification, and cued recall of images drawn from either semantic or autobiographical memories. Overall the findings lent strong support to these hypotheses. It is concluded [Part 3] that autobiographical and semantic memories of the same items differ in terms of the information which they represent and in their forms of organization version of SED in memory. These findings validated the revised which emphasised representational differences such as content and organization rather than process differences and also supported the proposal that that the two classes of memory were represented in a unitary memory store rather than in functionally separate memory stores. The implications of the findings for the study of autobiographical memory, semantic memory, categorization, and imagery are discussed.

description: A flat complete causal Lorentzian manifold is called {\it strictly causal} if the past and the future of each its point are closed near this point. We consider strictly causal manifolds with unipotent holonomy groups and assign to a manifold of this type four nonnegative integers (a signature) and a parabola in the cone of positive definite matrices. Two manifolds are equivalent if and only if their signatures coincides and the corresponding parabolas are equal (up to a suitable automorphism of the cone and an affine change of variable). Also, we give necessary and sufficient conditions, which distinguish parabolas of this type among all parabolas in the cone.

description: Charles P. O'Brien, MD, PhD, is a research scientist, medical educator and a leading expert in the science and treatment of addiction. He is board certified in neurology, psychiatry and addiction psychiatry. He is Emeritus Professor of Psychiatry in the Perelman School of Medicine at the University of Pennsylvania. While serving as chief of psychiatry at the Veterans Administration (VA) Medical Center in Philadelphia. In 1971 Dr. O'Brien founded and became director of a clinical research program consisting of a group of VA and University of Pennsylvania scientists. From 1971 until 2013, he served as director of this research center, called the Center for Studies of Addiction at the University of Pennsylvania. He and the center's other researchers made many discoveries about the treatment of addictive disorders, and published their research findings in more than 500 research papers, all authored or co-authored by O'Brien, and published in peer-reviewed scientific journals. Dr. O'Brien has chaired or served as a member of many Institute of Medicine committees dealing with science and drug abuse policy matters and from 2007 to 2013, served as chairperson of the Substance Use Disorders Committee of the American Psychiatric Association. The purpose of this committee was to revise the primary classification system of the DSM-5, that psychiatrists use in diagnosing mental illnesses, including addiction disorders. There was no validated measure of addiction in the 1970s, so Dr. O'Brien began work, together with A. Thomas McLellan, PhD, to develop the "Addiction Severity Index", a tool that was later translated into over 30 languages and which by 2012 was being used throughout the world to determine the extent of patients' problems and tailor appropriate treatment approaches. Naltrexone, an opioid receptor antagonist, was already in use by the early 1980s as a medication for treating addiction to heroin and other opioids, but not alcohol addiction. Based on animal studies, O'Brien in the 1980s theorized that alcohol produced pleasure by releasing endorphins – the brain's naturally occurring opioids. Dr. O'Brien and his colleagues discovered a new treatment for alcoholism using naltrexone. In 1995, the FDA approved naltrexone for the treatment of alcohol dependence, ushering in a new era of alcoholism treatment which, prior to this time, had been limited mainly to psychotherapy and psychosocial interventions such as Alcoholics Anonymous.

description: Stochastic compositional optimization generalizes classic (non-compositional) stochastic optimization to the minimization of compositions of functions. Each composition may introduce an additional expectation. The series of expectations may be nested. Stochastic compositional optimization is gaining popularity in applications such as reinforcement learning and meta learning. This paper presents a new Stochastically Corrected Stochastic Compositional gradient method (SCSC). SCSC runs in a single-time scale with a single loop, uses a fixed batch size, and guarantees to converge at the same rate as the stochastic gradient descent (SGD) method for non-compositional stochastic optimization. This is achieved by making a careful improvement to a popular stochastic compositional gradient method. It is easy to apply SGD-improvement techniques to accelerate SCSC. This helps SCSC achieve state-of-the-art performance for stochastic compositional optimization. In particular, we apply Adam to SCSC, and the exhibited rate of convergence matches that of the original Adam on non-compositional stochastic optimization. We test SCSC using the portfolio management and model-agnostic meta-learning tasks.

description: The recent increase of national interests in Europe makes the results of the future negotiations on the EU Multiannual Financial Framework (MFF) uncertain. The objective of the paper is to present the budget negotiations of two recent MFF’s (2007-2013 and 2014-2020) and to forecast its potential shape beyond 2020. Standard game theory and the theory of moves are used to model the negotiations on the budget between the European Commission and net payers of the EU budget. The results demonstrate that net payers can initially accept an increase of the budgets of both the Common Agricultural Policy (CAP) and the Cohesion Policy. However, attempts to over-increase the financing of the CAP in reference to the Cohesion Policy can motivate them to freeze the budget at the current level. / Synopsis. Wzrost interesów narodowych i ruchów anty-integracyjnych w Europie stawiają pod znakiem zapytania wyniki kolejnych negocjacji dotyczących wieloletnich ram finansowych UE. Celem niniejszej pracy jest prezentacja ustaleń negocjacji budżetowych dla lat 2007-2013 i 2014-2020 oraz próba wykorzystania teorii gier do przewidywania wielkości i struktury budżetu UE w przyszłości na przykładzie preferencji wybranych aktorów procesu decyzyjnego. W artykule wykorzystano elementy tradycyjnej teorii gier niekooperacyjnych oraz jej rozwinięcie w postaci teorii przejść. Z przeprowadzonej gry między Komisją Europejską a płatnikami netto należy wnioskować, że w kolejnych negocjacjach budżetowych płatnicy mogą początkowo zaakceptować zwiększenie budżetu na Wspólną Politykę Rolną oraz Politykę Spójności (PS), przy czym korzystniejszym dla nich rozwiązaniem byłby wzrost w większym zakresie budżetu PS. Z kolei próby nadmiernego zwiększenia budżetu polityki rolnej w stosunku do PS mogą ostatecznie doprowadzić do zamrożenia przez płatników netto budżetu UE na obecnym poziomie.
