description: We report a simulation study for bottle-brush polymers grafted on a rigid backbone. Using a standard coarse-grained bead-spring model extensive molecular dynamics simulations for such macromolecules under good solvent conditions are performed. We consider a broad range of parameters and present numerical results for the monomer density profile, density of the untethered ends of the grafted flexible backbones and the correlation function describing the range that neighboring grafted bottle-brushes are affected by the presence of the others due to the excluded volume interactions. The end beads of the flexible backbones of the grafted bottle-brushes do not access the region close to the rigid backbone due to the presence of the side chains of the grafted bottle-brush polymers, which stretch further the chains in the radial directions. Although a number of different correlation lengths exist as a result of the complex structure of these macromolecules, their properties can be tuned with high accuracy in good solvents. Moreover, qualitative differences with "typical" bottle-brushes are discussed. Our results provide a first approach to characterizing such complex macromolecules with a standard bead spring model.

description: Bacteria of many species rely on a simple molecule, the intracellular secondary messenger c-di-GMP (Bis-(3'-5')-cyclic dimeric guanosine monophosphate), to make a vital choice: whether to stay in one place and form a biofilm, or to leave it in search of better conditions. The c-di-GMP network has a bow-tie shaped architecture that integrates many signals from the outside world—the input stimuli—into intracellular c-di-GMP levels that then regulate genes for biofilm formation or for swarming motility—the output phenotypes. How does the ‘uninformed’ process of evolution produce a network with the right input/output association and enable bacteria to make the right choice? Inspired by new data from 28 clinical isolates of Pseudomonas aeruginosa and strains evolved in laboratory experiments we propose a mathematical model where the c-di-GMP network is analogous to a machine learning classifier. The analogy immediately suggests a mechanism for learning through evolution: adaptation though incremental changes in c-di-GMP network proteins acquires knowledge from past experiences and enables bacteria to use it to direct future behaviors. Our model clarifies the elusive function of the ubiquitous c-di-GMP network, a key regulator of bacterial social traits associated with virulence. More broadly, the link between evolution and machine learning can help explain how natural selection across fluctuating environments produces networks that enable living organisms to make sophisticated decisions.

description: We propose a random matrix model for families of elliptic curve L-functions of finite conductor. A repulsion of the critical zeros of these L-functions away from the center of the critical strip was observed numerically by S. J. Miller in 2006; such behaviour deviates qualitatively from the conjectural limiting distribution of the zeros (for large conductors this distribution is expected to approach the one-level density of eigenvalues of orthogonal matrices after appropriate rescaling).Our purpose here is to provide a random matrix model for Miller's surprising discovery. We consider the family of even quadratic twists of a given elliptic curve. The main ingredient in our model is a calculation of the eigenvalue distribution of random orthogonal matrices whose characteristic polynomials are larger than some given value at the symmetry point in the spectra. We call this sub-ensemble of SO(2N) the excised orthogonal ensemble. The sieving-off of matrices with small values of the characteristic polynomial is akin to the discretization of the central values of L-functions implied by the formula of Waldspurger and Kohnen-Zagier.The cut-off scale appropriate to modeling elliptic curve L-functions is exponentially small relative to the matrix size N. The one-level density of the excised ensemble can be expressed in terms of that of the well-known Jacobi ensemble, enabling the former to be explicitly calculated. It exhibits an exponentially small (on the scale of the mean spacing) hard gap determined by the cut-off value, followed by soft repulsion on a much larger scale. Neither of these features is present in the one-level density of SO(2N). When N tends to infinity we recover the limiting orthogonal behaviour. Our results agree qualitatively with Miller's discrepancy. Choosing the cut-off appropriately gives a model in good quantitative agreement with the number-theoretical data.

description: Background

Depression is under-diagnosed and under-treated in most areas of the US. New York City is currently looking to close gaps in identifying and treating depression through the adoption of a screening and collaborative care model deployed throughout the city.

Methods

We examine the cost-effectiveness of universal two-stage screening with the 2- and 9-item Patient Health Questionnaires (PHQ-2 and PHQ-9) in New York City followed by collaborative care for those who screen positive. We conducted microsimulations on hypothetical adult participants between ages 20 and 70.

Results

The incremental cost-effectiveness of the interventions over the average lifespan of a 20-year-old adult in NYC is approximately $1,726/QALY gained (95% plausible interval: cost-saving, $10,594/QALY gained).

Conclusions

Two-stage screening coupled with collaborative care for depression in the clinical setting appears to be significantly less expensive than most clinical preventive interventions, such as HIV screening in high-risk patients. However, effectiveness is dependent on the city’s ability to manage scale up of collaborative care models.

description: We investigate in more depth the issue of backreaction in models that attempt at generating cosmological magnetic fields at inflation. By choosing different, physically motivated, parametrisations, we are able to isolate the core of the problem, namely the existence, alongside the wanted magnetic field, of its electric counterpart, which turns out quite generally to be stronger and redder. We were also able to identify a few more interwoven weak spots (the typically very high scale of inflation, the width of the spectrum of modes processed by inflation, the blindness of the amplification mechanism to the energy scale processed), in a way independent on the specifications of the coupling between inflation and electromagnetism. Despite having stripped down the problem to the core, the obstacles encountered appear insurmountable, thereby posing a challenge to inflation as the incubator of cosmological magnetism.

Age and ageism in the sentencing of older adults
Creators: name: Love, Helene
Publisher: name: University of British Columbia
Year: 2011

description: As Canada's population ages, judges will increasingly have to determine what sorts of sentences are appropriate for aged criminal offenders. This thesis sought to uncover current trends in judicial practices by asking the research questions: Does old age have an impact on a sentence? When, why, and in what way? Are these practices ageist? This thesis investigates these important questions by first comparing the sentences handed down to older adults (those aged older than 60 years) with those handed down to younger adults (those aged under 60 years) to see if old age has an impact on the duration of penal sentences. While the duration of the sentences handed down to older adults compared to younger adults are not significantly different, in many cases, judges explicitly state that old age operates as a factor that commands leniency in a sentence. Next, a qualitative analysis of the legal texts of the judgments examines when, why and in what way old age influences sentencing practices. These practices are then submitted to an age based critique. Old age impacts sentencing practices in a variety of ways, and can either increase or decrease the duration of a prison term. This paper concludes that, in most cases, judges adopt an age-neutral approach to sentencing.

description: The relation between free carrier absorption and intersubband transitions in semiconductor heterostructures is resolved by comparing a sequence of structures. Our numerical and analytical results show how free carrier absorption evolves from the intersubband transitions in the limit of an infinite number of wells with vanishing barrier width. It is explicitly shown that the integral of the absorption over frequency matches the value obtained by the f-sum rule. This shows that a proper treatment of intersubband transitions is fully sufficient to simulate the entire electronic absorption in heterostructure THz devices.

description: We have investigated the thermal Hall effect of magnons for various ferromagnetic insulators. For pyrochlore ferromagnetic insulators Lu$_2$V$_2$O$_7$, Ho$_2$V$_2$O$_7$, and In$_2$Mn$_2$O$_7$, finite thermal Hall conductivities have been observed below the Curie temperature $T_C$ . From the temperature and magnetic field dependences, it is concluded that magnons are responsible for the thermal Hall effect. The Hall effect of magnons can be well explained by the theory based on the Berry curvature in momentum space induced by the Dzyaloshinskii-Moriya (DM) interaction. The analysis has been extended to the transition metal (TM) oxides with perovskite structure. The thermal Hall signal was absent or far smaller in La$_2$NiMnO$_6$ and YTiO$_3$, which have the distorted perovskite structure with four TM ions in the unit cell. On the other hand, a finite thermal Hall response is discernible below $T_C$ in another ferromagentic perovskite oxide BiMnO$_3$, which shows orbital ordering with a larger unit cell. The presence or absence of the thermal Hall effect in insulating pyrochlore and perovskite systems reflect the geometric and topological aspect of DM-induced magnon Hall effect.

description: Ae. albopictus, an invasive mosquito vector now endemic to much of the northeastern US, is a significant public health threat both as a nuisance biter and vector of disease (e.g. chikungunya virus). Here, we aim to quantify the relationships between local environmental and meteorological conditions and the abundance of Ae. albopictus mosquitoes in New York City. Using statistical modeling, we create a fine-scale spatially explicit risk map of Ae. albopictus abundance and validate the accuracy of spatiotemporal model predictions using observational data from 2016. We find that the spatial variability of annual Ae. albopictus abundance is greater than its temporal variability in New York City but that both local environmental and meteorological conditions are associated with Ae. albopictus numbers. Specifically, key land use characteristics, including open spaces, residential areas, and vacant lots, and spring and early summer meteorological conditions are associated with annual Ae. albopictus abundance. In addition, we investigate the distribution of imported chikungunya cases during 2014 and use these data to delineate areas with the highest rates of arboviral importation. We show that the spatial distribution of imported arboviral cases has been mostly discordant with mosquito production and thus, to date, has provided a check on local arboviral transmission in New York City. We do, however, find concordant areas where high Ae. albopictus abundance and chikungunya importation co-occur. Public health and vector control officials should prioritize control efforts to these areas and thus more cost effectively reduce the risk of local arboviral transmission. The methods applied here can be used to monitor and identify areas of risk for other imported vector-borne diseases.

description: Weakly-bound van d r \i\ aal clu t r of 2 0 and C02 were studied in a pulsed supersonic slit expansion probed with a tunable diode la er. The first observation of a polar isomer of N 2 0 dim r in t h region of the v1 fundamental band wa mad . Structural parameter were determined by recording and analyzing the spectra of the 15 N- ubstituted isotopic form and h normal pecies. The polar form of the dimer has a lipped parallel t ructur, rather similar to the slipped antiparallel structure of the nonpolar form but wit h a slightly larger intermolecular distance. Litrature assignments of the combination band (rv2 249 cm- 1) involving the intermolecular torional vibration was corrected. In addition a higher frequency combination band involving the intermolecular disrotation of the monomers (Bu intermolecular bend) for both (14 2 0 )2 and (15 2 0 )2 were measured and analyzed. nitrous oxide trim r was also studied. A previous empirical structural culation on (14 2 0 )3 has suggested a noncy lie barrel-shaped structure; having no specific symmetry. In this structure, the t hr contiunt monomers are in equivalent giving n to the infrared band. We recorded and analyzed the three expected band for the 15 -substituted ioopic form and the normal pecie. Three weaker rim r combination bands were also observed. Each band involves the sum of one of the previously observed intramolecular trim r vibrations plus an intermolecular vibration (van der Waal str tch orb nd). Possible vibrational assignment forth combination band are discussed based on their rotational structure and t h ru ur of the trimer. W also carried out a number of new measurements on C0 2 cluster. Spectrum of the (12 C0 2 ) 2 in the v3 fundamental region has been previously studied showing a planar lipped-parallal structure with c ntrosymmetric C2h ymmetry. Here, we report our own analyses of t his band as well as analyses of t he spectra of t he (13 CO2 )2 and 12 CO2 - 13 CO2 , clarifying t he role of resonant and non-resonant vibrational shift . Moreover, observation of a combination band of the (12CO2 ) 2 provides the first experimental intermolecular vibrational frequency for the dimer. Possible vibrational assignments are discussed . Two new parallel bands of t he cyclic (12CO2)3 in the v3 fundamental region were also observed. This isomer of t he t rimer has been previously found to be a symmetric top with planar structure and C3h symmetry. The band were assigned as a combination of intramolecular CO2 monomer v3 stretch and intermolecular out-of-pl an torsion. This provides the first measurement of two intermolecular vibrational frequencies for the cyclic trimer.

Dabei differenzieren wir zwischen Projekten, deren primäres Ziel es ist, eine Ressource aufzubauen (ressourcenschaffende Projekte, kurz RP) und solchen, die zur Beantwortung einer konkreten Forschungsfrage Daten sammeln und auswerten (Forschungsprojekte, kurz FP). Wir argumentieren dafür, dass bei den offenkundigen Unterschieden zwischen beiden Projektarten die grundsätzlichen Ansprüche an das alltägliche Forschungsdatenmanagement im Kern sehr ähnlich (wenn auch unterschiedlich akzentuiert und skaliert) sind. Diese Ähnlichkeit rührt nicht zuletzt daher, dass im Rahmen von FP gesammelte Daten in Bezug auf das Projektziel primär Mittel zum Zweck sein mögen, sie jedoch bereits im Arbeitsprozess in unterschiedlichem Maß von unterschiedlichen Beteiligten genutzt werden. Wir gehen konkret auf die Aspekte Datenorganisation und -verwaltung, Metadaten, Dokumentation und Dateiformate und deren Anforderungen in den verschiedenen Projekttypen ein. Schließlich diskutieren wir Lösungsansätze dafür, Aspekte des Forschungsdatenmanagements auch in (kleineren) Forschungsprojekten nicht post-hoc, sondern bereits in der Projektplanung als Teil der alltäglichen Arbeit zu berücksichtigen und entsprechende Unterstützung in der Forschungsinfrastruktur vorzusehen.

description: The thermodynamic and transport properties of the unitary Fermi gas at finite temperature T are governed by a quantum critical point at T=0 and zero density. We compute the universal shear viscosity to entropy ratio η/s in the high-temperature quantum critical regime T>>|μ| and find that this strongly coupled quantum fluid comes close to perfect fluidity η/s=\hbar/(4πk_B). Using a controlled large-N expansion we show that already at the first non-trivial order the equation of state and the Tan contact density C agree well with the most recent experimental measurements and theoretical Luttinger-Ward and Bold Diagrammatic Monte Carlo calculations.

description: We study the electromagnetic coupling of massless higher-spin fermions in flat space. Under the assumptions of locality and Poincare invariance, we employ the BRST-BV cohomological methods to construct consistent parity-preserving off-shell cubic 1-s-s vertices. Consistency and non-triviality of the deformations not only rule out minimal coupling, but also restrict the possible number of derivatives. Our findings are in complete agreement with, but derived in a manner independent from, the light-cone-formulation results of Metsaev and the string-theory-inspired results of Sagnotti-Taronna. We prove that any gauge-algebra-preserving vertex cannot deform the gauge transformations. We also show that in a local theory, without additional dynamical higher-spin gauge fields, the non-abelian vertices are eliminated by the lack of consistent second-order deformations.

description: Purpose

Breast conserving surgery (BCS) has become the preferred surgical option for the management of patients with nonmetastatic breast cancer in high-income countries. However, little is known about the distribution and determinants of BCS in low-and middle-income countries, especially those with high HIV prevalence.

Methods

We compared demographic and clinical characteristics of female patients who received BCS and those who received total mastectomy (TM) for nonmetastatic invasive carcinoma of the breast in Soweto, South Africa, 2009–2011. We also developed a multivariable logistic regression model of predictors of type of surgery.

Results

Of 445 patients, 354 (80%) underwent TM and 91 (20%) BCS. Of 373 patients screened for HIV, 59 (15.8%) tested positive. Eighty-two of 294 patients with stage I/II disease (28%), but just 9 of 151 (6%) with stage III disease had BCS (p<0.001). All women who received BCS (except for seven who received completion mastectomy within 6 weeks of BCS) and 235 (66.4%) women who received TM were referred for radiation therapy (RT). In our multivariable analysis, age group 50–59 years (OR = 2.28, 95% CI = 1.1–4.8) and ≥70 years (OR = 9.55, 95% CI = 2.9–31.2) vs. age group <40 years, stage at diagnosis (stage II (OR = 3.79, 95% CI = 1.6–8.2) and stage III (OR = 27.8, 95% CI = 9.0–78.8) vs. stage 1, HIV (HIV positive (OR = 3.19, 95% CI = 1.3–7.9) vs. HIV negative) and HER2-enriched subtype (OR = 3.50, 95% CI = 1.2–10.1) vs. triple negative were independently associated with TM.

Conclusion

TM was more common than BCS among patients with nonmetastatic breast cancer in Soweto, not only among patients with locally advanced disease at diagnosis, but also among women with stage I and II disease.

description: GTPase molecules are important regulators in cells that continuously run through an activation/deactivation and membrane-attachment/membrane-detachment cycle. Activated GTPase is able to localize in parts of the membranes and to induce cell polarity. As feedback loops contribute to the GTPase cycle and as the coupling between membrane-bound and cytoplasmic processes introduces different diffusion coefficients a Turing mechanism is a natural candidate for this symmetry breaking. We formulate a mathematical model that couples a reaction-diffusion system in the inner volume to a reaction-diffusion system on the membrane via a flux condition and an attachment/detachment law at the membrane. We present a reduction to a simpler non-local reaction-diffusion model and perform a stability analysis and numerical simulations for this reduction. Our model in principle does support Turing instabilities but only if the lateral diffusion of inactivated GTPase is much faster than the diffusion of activated GTPase.

Extension and exact realization of the Heller's derivative rule
Creators: name: Yamani, Hashim A.
name: Alhaidari, Abdulaziz D.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Mathematical Physics (math-ph)

description: The accuracy of the Heller's derivative rule to calculate the numerical weights associated with discretized energy spectrum is enhanced by Broad's extension which adds (N-1) more interpolating points to the original N points. The extension scheme is then used to show how to realize the rule without any approximation.

description: Progress in modern neuroscience critically depends on our ability to observe the activity of large neuronal populations with cellular spatial and high temporal resolution. However, two bottlenecks constrain efforts towards fast imaging of large populations. First, the resulting large video data is challenging to analyze. Second, there is an explicit tradeoff between imaging speed, signal-to-noise, and field of view: with current recording technology we cannot image very large neuronal populations with simultaneously high spatial and temporal resolution. Here we describe multi-scale approaches for alleviating both of these bottlenecks. First, we show that spatial and temporal decimation techniques based on simple local averaging provide order-of-magnitude speedups in spatiotemporally demixing calcium video data into estimates of single-cell neural activity. Second, once the shapes of individual neurons have been identified at fine scale (e.g., after an initial phase of conventional imaging with standard temporal and spatial resolution), we find that the spatial/temporal resolution tradeoff shifts dramatically: after demixing we can accurately recover denoised fluorescence traces and deconvolved neural activity of each individual neuron from coarse scale data that has been spatially decimated by an order of magnitude. This offers a cheap method for compressing this large video data, and also implies that it is possible to either speed up imaging significantly, or to “zoom out” by a corresponding factor to image order-of-magnitude larger neuronal populations with minimal loss in accuracy or temporal resolution.

Austerity Measures: The New Greek Poetry: Introduction

description: Not since the Colonels’ Dictatorship in the early 1970s, when poets such as Katerina Anghelaki-Rooke, Jenny Mastoraki, and Pavlina Pampoudi first appeared, has there been such an abundance of poetry being written, nor such a multitude of projects undertaken. Indeed, the historical affinity does not stop there: it is those same poets of the Dictatorship who are doing the lion’s share of mentoring in the new generation. The present anthology samples this living tradition, bearing witness not only to the hard lives being led in Greece and the Balkans today, but also to what poetry does best: offering new ways to imagine what can be radically different realities.

description: Removal of the quenched approximation in the mechanism which produced an analytic estimate of quark-binding potentials, along with a reasonable conjecture of the color structure of the nucleon formed by such a binding potential, is shown to generate an effective, nucleon scattering and binding potential. The mass-scale factor on the order of the pion mass, previously introduced to define transverse imprecision of quark coordinates, is again used, while the strength of the potential is proportional to the square of a renormalized QCD coupling constant. The potential so derived does not include corrections due to spin, angular momentum, nucleon structure, and electroweak interactions; rather, it is qualitative in nature, showing how Nuclear Physics can arise from fundamental QCD.

Tilting Bundles on Rational Surfaces and Quasi-Hereditary Algebras

description: Let $X$ be any rational surface. We construct a tilting bundle $T$ on $X$. Moreover, we can choose $T$ in such way that its endomorphism algebra is quasi-hereditary. In particular, the bounded derived category of coherent sheaves on $X$ is equivalent to the bounded derived category of finitely generated modules over a finite dimensional quasi-hereditary algebra $A$. The construction starts with a full exceptional sequence of line bundles on $X$ and uses universal extensions. If $X$ is any smooth projective variety with a full exceptional sequence of coherent sheaves (or vector bundles, or even complexes of coherent sheaves) with all groups $\mExt^q$ for $q \geq 2$ vanishing, then $X$ also admits a tilting sheaf (tilting bundle, or tilting complex, respectively) obtained as a universal extension of this exceptional sequence.

description: We report on the first simultaneous observation of an H-alpha Moreton wave, the corresponding EUV fast coronal waves, and a slow and bright EUV wave (typical EIT wave). Associated with an X6.9 flare that occurred on 2011 August 9 at the active region NOAA 11263, we observed a Moreton wave in the H-alpha images taken by the Solar Magnetic Activity Research Telescope (SMART) at Hida Observatory of Kyoto University. In the EUV images obtained by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamic Observatory (SDO) we found not only the corresponding EUV fast "bright" coronal wave, but also the EUV fast "faint" wave that is not associated with the H-alpha Moreton wave. We also found a slow EUV wave, which corresponds to a typical EIT wave. Furthermore, we observed, for the first time, the oscillations of a prominence and a filament, simultaneously, both in the H-alpha and EUV images. To trigger the oscillations by the flare-associated coronal disturbance, we expect a coronal wave as fast as the fast-mode MHD wave with the velocity of about 570 - 800 km/s. These velocities are consistent with those of the observed Moreton wave and the EUV fast coronal wave.

Literature Between Languages and Its Lessons for Translation

description: As I considered a lecture topic that would honor the translator and ambassador of Greek letters Kirnon Friar, I found myself pondering the collection of translations I was editing of Katerina Anghelaki-Rooke's poetry. Friar was Anghelaki-Rooke's first translator into English and a great supporter of hers, especially during the difficult years of censorship under the Colonels (1967-1974). Her poetry fit into the last category: Greek literature that isn't about America, but that somehow registers the pressure of English. Editing her work I was struck by how easily her Greek translated into English. At times it seemed as if her poetry had been thought-out in English. In honor of Friar I want to address the relation between Greek and English in Greek poetry, in particular the case of Anghelaki-Rooke. How might her poetry, situated at the edge of Greek and always in conversation with English, help us see the possibilities that multilingual literature has to offer translation?
Translating a Canonical Author: C. P. Cavafy

description: Translation, Walter Benjamin reminds us, involves the afterlife of the work, not the author’s life. Teaching canonical works with attention to the history of their survival enables students to move away from fixed notions of authorship and invention. Translation becomes a hermeneutic practice worthy of study in its own right, where learning how to interpret is indistinguishable from learning how to translate into different media. These points form the basic rationale of my course on C. P. Cavafy (1863–1933), a poet of the Greek diaspora who lived in Alexandria and profoundly influenced many prose writers, poets, and artists, from E. M. Forster and Marguerite Yourcenar to James Merrill and Duane Michals.
