description: We propose a novel method for sorting events of multiparticle production according to the azimuthal anisotropy of their momentum distribution. Although the method is quite general, we advocate its use in analysis of ultra-relativistic heavy-ion collisions where large number of hadrons is produced. The advantage of our method is that it can automatically sort out samples of events with histograms that indicate similar distributions of hadrons. It takes into account the whole measured histograms with all orders of anisotropy instead of a specific observable (e.g. $v_2$, $v_3$, $q_2$). It can be used for more exclusive experimental studies of flow anisotropies which are then more easily compared to theoretical calculations. It may also be useful in the construction of mixed-events background for correlation studies as it allows to select events with similar momentum distribution.

description: This study combines data from the Panel Study of Income Dynamics with data from four censuses to examine the effects of foreign-born populations in the immediate neighborhood of residence and surrounding neighborhoods on the residential mobility decisions of native-born black and white householders. We find that the likelihood of out-mobility for native householders is significantly and positively associated with the relative size of, and increases in, the immigrant population in the neighborhood. Consistent with theoretical arguments related to the distance dependence of mobility, large concentrations of immigrants in surrounding areas reduce native out-mobility, presumably by reducing the attractiveness of the most likely mobility destinations. A sizable share of local immigration effects can be explained by the mobility-related characteristics of native-born individuals living in immigrant-populated areas, but the racial composition of the neighborhood (for native whites) and local housing market conditions (for native blacks) also are important mediating factors. The implications of these patterns for processes of neighborhood change and broader patterns of residential segregation are discussed.

description: Two long-standing research problems of interest to sociologists are sources of variations in social inequalities and differential contributions of the temporal dimensions of age, time period, and cohort to variations in social phenomena. Recently, scholars have introduced a model called Variance Function Regression for the study of the former problem, and a model called Hierarchical Age-Period-Cohort regression has been developed for the study of the latter. This article presents an integration of these two models as a means to study the evolution of social inequalities along distinct temporal dimensions. We apply the integrated model to survey data on subjective health status. We find substantial age, period, and cohort effects, as well as gender differences, not only for the conditional mean of self-rated health (i.e., between-group disparities), but also for the variance in this mean (i.e., within-group disparities)—and it is detection of age, period, and cohort variations in the latter disparities that application of the integrated model permits. Net of effects of age and individual-level covariates, in recent decades, cohort differences in conditional means of self-rated health have been less important than period differences that cut across all cohorts. By contrast, cohort differences of variances in these conditional means have dominated period differences. In particular, post-baby boom birth cohorts show significant and increasing levels of within-group disparities. These findings illustrate how the integrated model provides a powerful framework through which to identify and study the evolution of variations in social inequalities across age, period, and cohort temporal dimensions. Accordingly, this model should be broadly applicable to the study of social inequality in many different substantive contexts.

description: This study demonstrates body mass in middle and late adulthood as a consequence of the complex interplay among individuals’ genes, lifetime socioeconomic experiences, and the historical context in which they live. Drawing on approximately 9,000 genetic samples from the Health and Retirement Study, we first investigate how socioeconomic status (SES) over the life course moderates the impact of 32 established obesity-related genetic variants on body mass index (BMI) in middle and late adulthood. Further, we consider differences across birth cohorts in the genetic influence on BMI and cohort variations in the moderating effects of life-course SES on the genetic influence. Our analyses suggest that persistently low SES over the life course or downward mobility (e.g., high SES in childhood but low SES in adulthood) amplified the genetic influence on BMI, while persistently high SES or upward mobility (e.g., low SES in childhood but high SES in adulthood) compensated for such influence. For more recent birth cohorts, while the genetic influence on BMI became stronger, the moderating effects of lifetime SES on the genetic influence were weaker compared to earlier cohorts. We discuss these findings in light of social changes during the obesity epidemic in the United States.

description: We investigate the preservation of unitarity in a Lorentz and CPT-violating QED model containing higher-order operators. In particular, we consider modifications in the fermion sector with dimension-five operators. The higher-order operators lead to an indefinite metric and a pseudo-unitarity relation for the $S$-matrix. However, we show that the pseudo-unitarity condition can be promoted to a genuine unitarity relation by i) restricting the energies to the effective region far below the Planck mass and ii) considering stable particles to have positive metric. In the context of the optical theorem, we focus on the one-loop Bhabha and Compton scattering processes. We show that no ghost states get propagated through the cuts, thus satisfying the unitarity condition. Further, we show that discontinuities of propagators are equivalent to replacing physical Dirac functionals in the cutting equation. The physical Dirac functionals are defined to select only mode solutions of stable particles. The provided extension of Cutkosky rule may be helpful for analyzing perturbative unitarity in higher-order diagrams.

description: Online media provides opportunities for marketers through which they can deliver effective brand messages to a wide range of audiences. Advertising technology platforms enable advertisers to reach their target audience by delivering ad impressions to online users in real time. In order to identify the best marketing message for a user and to purchase impressions at the right price, we rely heavily on bid prediction and optimization models. Even though the bid prediction models are well studied in the literature, the equally important subject of model evaluation is usually overlooked. Effective and reliable evaluation of an online bidding model is crucial for making faster model improvements as well as for utilizing the marketing budgets more efficiently. In this paper, we present an experimentation framework for bid prediction models where our focus is on the practical aspects of model evaluation. Specifically, we outline the unique challenges we encounter in our platform due to a variety of factors such as heterogeneous goal definitions, varying budget requirements across different campaigns, high seasonality and the auction-based environment for inventory purchasing. Then, we introduce return on investment (ROI) as a unified model performance (i.e., success) metric and explain its merits over more traditional metrics such as click-through rate (CTR) or conversion rate (CVR). Most importantly, we discuss commonly used evaluation and metric summarization approaches in detail and propose a more accurate method for online evaluation of new experimental models against the baseline. Our meta-analysis-based approach addresses various shortcomings of other methods and yields statistically robust conclusions that allow us to conclude experiments more quickly in a reliable manner. We demonstrate the effectiveness of our evaluation strategy on real campaign data through some experiments.

description: We consider WIYN/Hydra spectra of 329 photometric candidate members of the 420-Myr-old open cluster M48, and report Lithium detections or upper limits for 234 members and likely members. The 171 single members define a number of notable Li-mass trends, some delineated even more clearly than in Hyades/Praesepe: The giants are consistent with subgiant Li dilution and prior MS Li depletion due to rotational mixing. A dwarfs (8600-7700K) have upper limits higher than the presumed initial cluster Li abundance. Two of five late A dwarfs (7700- 7200K) are Li-rich, possibly due to diffusion, planetesimal accretion, and/or engulfment of hydrogen-poor planets. Early F dwarfs already show evidence of Li depletion seen in older clusters. The Li-$T_{\rm eff}$ trends of the Li Dip (6675-6200K), Li Plateau (6200-6000K), and G and K dwarfs (6000-4000K) are very clearly delineated and are intermediate to those of the 120-Myr-old Pleiades and 650-Myr-old Hyades/Praesepe, which suggests a sequence of Li depletion with age. The cool side of the Li Dip is especially well-defined with little scatter. The Li-$T_{\rm eff}$ trend is very tight in the Li Plateau and early G dwarfs, but scatter increases gradually for cooler dwarfs. These patterns support and constrain models of the universally dominant Li depletion mechanism for FGK dwarfs, namely rotational mixing due to angular momentum loss; we discuss how diffusion and gravity-wave driven mixing may also play roles. For late-G/K dwarfs, faster rotators show higher Li than slower rotators, and we discuss possible connections between angular momentum loss and Li depletion.

description: Bouncing droplets on a vibrating fluid bath can exhibit wave-particle behavior, such as being propelled by interacting with its own wave field. These droplets seem to walk across the bath, and thus are dubbed walkers. Experiments have shown that walkers can exhibit exotic dynamical behavior indicative of chaos. While the integro-differential models developed for these systems agree well with the experiments, they are difficult to analyze mathematically. In recent years, simpler discrete dynamical models have been derived and studied numerically. The numerical simulations of these models show evidence of exotic dynamics such as period doubling bifurcations, Neimark--Sacker (N--S) bifurcations, and even chaos. For example, in [Gilet, PRE 2014], based on simulations Gilet conjectured the existence of a supercritical N-S bifurcation as the damping factor in his one-dimensional path model. We prove Gilet's conjecture and more; in fact, both supercritical and subcritical (N-S) bifurcations are produced by separately varying the damping factor and wave-particle coupling for all eigenmode shapes. Then we compare our theoretical results with some previous and new numerical simulations, and find complete qualitative agreement. Furthermore, evidence of chaos is shown by numerically studying a global bifurcation.

description: An iterative design strategy using three criteria was utilized to develop a peptidase-resistant substrate peptide for protein kinase B. Libraries of peptides possessing non-native amino acids were screened for time to 50% phosphorylation, degradation half-life within a lysate, and appearance of a dominant fragment. The lead peptide possessed a half-life of 92 ± 7 and 16 ± 2 min in HeLa and LNCaP cytosolic lysates, respectively, representing a 4.6- and 2.7-fold lifetime improvement over that of the starting peptide. The redesigned peptide possessed a 4.5-fold improvement in phosphorylation efficiency compared to the starting peptide. The same peptide fragments were formed when the lead peptide was incubated in a lysate or loaded into single cells although the fragments formed in significantly different ratios suggesting that distinct peptidases metabolized the peptide in the two preparations. The rate of peptide degradation and phosphorylation was on average 0.1 ± 0.2 zmol pg−1 s−1 and 0.04 ± 0.08 zmol pg−1 s−1, respectively, for single LNCaP cells loaded with 4 ± 8 μM of peptide. Peptidase-resistant kinase substrates should find wide-spread utility in both lysate-based and single-cell assays of kinase activity.

description: Little is known of warming effects on growth and defence of woody seedlings that potentially invade grasslands. We predicted that elevated temperatures would increase growth and spine length of Vachellia sieberiana seedlings growing (1) with or without grass in the dormant season and early growing season, but (2) only when grass cover is absent in the mid-late growing season. To test these predictions, 120 seedlings were grown in 20 field plots in the dormant season, early growing season, middle of the growing and late growing season. Ten plots were warmed with open-top chambers that raised air temperature by 1.0 to 2.5 °C depending on season. Warming generally increased growth metrics regardless of grass cover across seasons and generally increased spine length only when grass cover was absent. The results imply that under a warmer climate, V. sieberiana will thrive irrespective of grass cover.

description: It has been proposed that slingshot prominences may be a mass and angular momentum loss mechanism for rapidly rotating young stars. Stellar evolution models currently rely only on the wind as the angular momentum loss mechanism and do not include prominences. These models often require more angular momentum to be removed than the wind allows, and prominence ejection may hold at least part of the answer. This thesis aims to investigate the locations of prominence formation through mathematical modelling. The magnetic field structures that could support prominences are investigated, typically using two models: a magnetohydrostatic model and a stability method. The distributions of prominences around the star are calculated and, where possible, compared to observations. In some cases the magnetic field of the star is prescribed to be a simple field such as a dipole or quadrupole, and in others the magnetic field is generated from observations of the surface magnetic field, with the coronal magnetic field reconstructed from this, assuming the field is potential. This work finds that prominences can be formed both within the stellar wind of stars, and within the closed field region. With the magnetohydrostatic model, two classes of prominence are found: those close to the surface of the star that could be analogous to solar prominences, and those at very large distances from the stellar surface. Those in the second category may be ejected from the star and act as a mechanism for removing mass and angular momentum. The removal of mass and angular momentum by prominences was modelled using the stable point method, and it was found that for some stars within the sample of M-dwarfs, the prominences could be a significant angular momentum loss mechanism. Work here shows that whilst a tilted dipolar field can typically replicate the locations of observed prominences well, using observed prominence locations to infer the tilt of the dipole is not very effective due to the degeneracy of stable point locations. Overall, prominences are likely to be important contributors to the removal of angular momentum and therefore spin down of a star at certain points in its life, whilst they are typically left out of stellar evolution models. They are likely to be very common across young stars, however they are usually only observable when they transit the stellar disc and therefore they will often be missed by observations due to geometric effects. Those that are observed are likely only being partially observed, meaning that mass predictions from observations are underestimates.
POLO-LIKE KINASE CDC5 CONTRIBUTES TO MITOTIC SPINDLE ELONGATION VIA THE KINESIN-5 MOTOR PROTEIN CIN8
Creators: name: CLAUDI, CECILIA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: Proper chromosome segregation requires an orderly sequence of events, whereby spindle elongation follows the dissolution of sister chromatid linkages. Chromosome segregation starts at the onset of anaphase when the separase triggers the cleavage of cohesin, a protein complex that holds sister chromatids together. Next, chromatids are segregated into the daughter cells by the pulling force of the mitotic spindle. The mitotic spindle is a sophisticated and complex machinery built of microtubules, microtubule associated proteins and motor proteins. Despite the fundamental role of the mitotic spindle, the molecular mechanisms underlying its regulation remain elusive. Proper spindle function requires that microtubule dynamics are stabilized at anaphase. This change in microtubule dynamics is perceived as dictated by a shift in the balance of kinase and phosphatase activities in favor of the phosphatases. The finding that cells simultaneously lacking the polo-like kinase Cdc5 and the phosphatase Cdc14 cannot progress through anaphase albeit having cleaved cohesin due to defects in spindle elongation, challenges the view of mitotic exit as a time for protein dephosphorylation. The aim of my work is to understand the molecular mechanism by which the two proteins contribute to anaphase spindle elongation, with a particular focus on the role of Cdc5. We identified the kinesin 5 motor protein Cin8 as a key target of the ?Cdc14-Cdc5? spindle elongation pathway. We show that besides being dephosphorylated by Cdc14, Cin8 is also phosphorylated by Cdc5 on residues S409 and S441, and that this phosphorylation is crucial for the function of the kinesin in anaphase spindle elongation, likely because of the impact it has on the interaction between Cin8 and microtubules. Since these residues, S409 and S441, are located within a highly conserved stretch of amino acids, it will be interesting to test whether this regulation is conserved in other vertebrates as well. The finding that Cin8 is simultaneously a substrate of a kinase and a phosphatase sheds light on the complexity of mitotic exit regulation and is in complete agreement with recent data showing that approximately equal numbers of phosphosites are phosphorylated and dephosphorylated during mitotic progression and exit. Since it appears that phosphorylation and dephosphorylation events are equally important to the point that kinases and phosphatases cooperate to regulate the same substrates, the view of mitotic exit as the realm of phosphatases is dismantled and the continuous need for single molecule studies in addition to global analyses investigation is put forward.

description: Russia’s invasion of Ukraine has marked the start of a new geo-economic era for the EU. The invasion has dramatically intensified the EU’s ongoing economic and financial decoupling from Russia, which started in 2014, and adds to existing challenges, which are now assuming added salience: global economic decoupling between the US and China, the climate emergency and increasing irregular migration. Gaining a better understanding of the geo-economic challenges that the EU faces in its neighbouring regions and assessing their influence in relation to its peers and rivals are now of fundamental importance.
This study set out to measure the interconnectivity between the EU and its neighbouring countries and to compare these interconnections with those of the EU’s peers and rivals: the US, China and Russia. We have dealt with interconnectivity in five areas: trade, finance, technology and know-how, infrastructure and labour mobility. In doing so, we have sought to identify and measure the extent of these interconnections and to draw out the key geoeconomic implications for the EU.

description: We study the late time behavior of $n$-point spectral form factors (SFFs) in two-dimensional Witten-Kontsevich topological gravity, which includes both Airy and JT gravities as special cases. This is conducted in the small $\hbar$ expansion, where $\hbar \sim e^{- {1}/{G_N}}$ is the genus counting parameter and nonperturbative in Newton's constant $G_N$. For one-point SFF, we study its absolute square at two different late times. We show that it decays by power law at $t \sim \hbar^{-2/3}$ while it decays exponentially at $t \sim \hbar^{-1}$ due to the higher order corrections in $\hbar$. We also study general $n (\ge 2)$-point SFFs at $t \sim \hbar^{-1}$ in the leading order of the $\hbar$ expansion. We find that they are characterized by a single function, which is essentially the connected two-point SFF and is determined by the classical eigenvalue density $ρ_0(E)$ of the dual matrix integral. These studies suggest that qualitative behaviors of $n$-point SFFs are similar in both Airy and JT gravities, where our analysis in the former case is based on exact results.

description: The Glauber model analysis of the elastic $^{6,8}$He+$p$ scattering data at energies around 700 MeV/nucleon, measured in two separate experiments at GSI-Darmstadt, has been done using several phenomenological parametrizations of the nuclear matter density. By taking into account the new data points measured at the high momentum transfer, the nuclear matter radii of $^{6,8}$He were accurately determined from the Glauber model analysis of the data, with the spin-orbital interaction explicitly taken into account. The well-known geometry for the core and dineutron halo has been used with the new parametrizations of the $^{6}$He density to extract the detailed information on the structure of $^{6}$He in terms of the core and dineutron halo radii. An enhanced sensitivity of the data measured at the high momentum transfer to the core part of the $^{6,8}$He densities has been found.

description: We propose a new evolutionary process of protoplanetary disks "co-evolution of dust grains and protoplanetary disks", revealed by dust-gas two-fluid non-ideal magnetohydrodynamics simulations considering the growth of dust and associated changes in magnetic resistivity. We found that the dust growth significantly affects disk evolution by changing the coupling between the gas and magnetic field. Moreover, once the dust grains sufficiently grow and the adsorption of charged particles on dust grains becomes negligible, the physical quantities (e.g., density and magnetic field) of the disk are well described by characteristic power laws. In this disk structure, the radial profile of density is steeper and the disk mass is smaller than those of the model ignoring dust growth. We analytically derive these power laws from the basic equations of non-ideal magnetohydrodynamics. The analytical power laws are determined only by observable physical quantities, e.g., central stellar mass and mass accretion rate, and do not include difficult-to-determine parameters e.g., viscous parameter $α$. Therefore, our model is observationally testable and this disk structure is expected to provide a new perspective for future studies on protostar and disk evolution.

description: A microfabricated platform was developed for highly parallel and efficient colony picking, splitting and clone identification. A pallet array provided patterned cell colonies which mated to a second printing array composed of bridging microstructures formed by a supporting base and attached post. The posts enabled mammalian cells from colonies initially cultured on the pallet array to migrate to corresponding sites on the printing array. Separation of the arrays simultaneously split the colonies creating a patterned replica. Optimization of array elements provided transfer efficiencies greater than 90% using bridging posts of 30 μm diameter and 100 μm length and total colony numbers of 3000. Studies using five mammalian cell lines demonstrated that a variety of adherent cell types could be cultured and effectively split with printing efficiencies of 78–92%. To demonstrate the technique’s utility, clonal cell lines with siRNA knockdown of Coronin 1B were generated using the arrays and compared to a traditional FACS/Western Blotting-based approach. Identification of target clones required a destructive assay to identify cells with an absence of Coronin 1B brought about by the successful infection of interfering shRNA construct. By virtue of miniaturization and its parallel format, the platform enabled the identification and generation of 12 target clones from a starting sample of only 3900 cells and required only 5-man hours over 11 days. In contrast, the traditional method required 500,000 cells and generated only 5 target clones with 34-man hours expended over 47 days. These data support the considerable reduction in time, manpower and reagents using the miniaturized platform for clonal selection by destructive assay versus conventional approaches.

description: 1,3-butadiene (BD) is an important industrial chemical and a common environmental pollutant present in urban air. BD is classified as a human carcinogen based on epidemiological evidence for an increased incidence of leukemia in workers occupationally exposed to BD and its potent carcinogenicity in laboratory mice. A diepoxide metabolite of BD, 1,2,3,4-diepoxybutane (DEB), is considered the ultimate carcinogenic species of BD due to its ability to form genotoxic DNA-DNA cross-links. We have previously employed capillary HPLC-ESI+-MS/MS methods to quantify DEB-induced DNA-DNA conjugates, e.g. 1,4-bis-(guan-7-yl)-2,3-butanediol (bis-N7G-BD), 1-(guan-7-yl)-4-(aden-1-yl)-2,3-butanediol (N7G-N1A-BD), and 1,N6-(1-hydroxymethyl-2-hydroxypropan-1,3-diyl)-2′-deoxyadenosine (1,N6-HMHP-dA), in tissues of laboratory mice exposed to 6.25 – 625 ppm BD (Goggin et al. Cancer Research 69(6), 2479–2486, 2009). However, typical BD human exposure levels are 0.01 to 3.2 ppb in urban air and 1– 2.0 ppm in an occupational setting, requiring greater detection sensitivity for these critical lesions. In the present study, a nanoHPLC-nanoESI+-MS/MS method was developed for ultra-sensitive, accurate, and precise quantitation of bis-N7G-BD in tissues of laboratory mice treated with low ppm and sub-ppm concentrations of BD. The LOD value of the new method is 0.5 fmol/100 μg DNA, and the LOQ is 1.0 fmol/100 μg DNA, making it possible to quantify bis-N7G-BD adducts present at concentrations of 3 per 109 nucleotides. Bis-N7G-BD adduct amounts in liver tissues of mice exposed to 0.5, 1.0, 1.5 ppm BD for 2 weeks were 5.7 ± 3.3, 9.2 ± 1.5, and 18.6 ± 6.9 adducts per 109 nucleotides, respectively, suggesting that N7G-BD adduct formation is more efficient under low exposure conditions. To our knowledge, this is the first quantitative analysis of DEB specific DNA adducts following low ppm and sub-ppm exposure to BD.

description: Study of cell signaling often requires examination of the cellular dynamics under variation in the stimulant concentration. Such variation has typically been conducted by dispensing cell populations in a number of chambers or wells containing discrete concentrations. Such practice adds to the complexity associated with experimental or device design and requires substantial labor for implementation. Furthermore, there is also potential risk of missing important results due to the often arbitrary selection of discrete concentration values for testing. In this letter, we study NF-κB activation and translocation at the single cell level using a microfluidic device that generates continuously varying concentration gradient. We use only three device settings to cover stimulant (interleukin-1β) concentrations of four orders of magnitude (0.001-10 ng/ml). Such device allows us to study temporal dynamics of NF-κB in single cells under different stimulant concentrations by real-time imaging. Interestingly, our results reveal that while the percent of cells with NF-κB translocation decreases with lower stimulant concentration in the range of 0.1-0.001 ng/ml, the response time of such translocation remains constant, reflected by the single cell data.

description: We have investigated Vickers hardness and the thermodynamic properties of the recently discovered nanolaminate carbide Ti3SnC2 polymorphs using the first-principles calculations. The chemical bonding shows a combination of covalent, ionic and metallic types. The strong covalent bonding is mainly responsible for high Vickers hardness of Ti3SnC2 polymorphs. Thermodynamic properties are studied using the quasi-harmonic Debye model. The variation of bulk modulus, thermal expansion co-efficient, specific heats, and Debye temperature with applied pressure (P) and temperature (T) are investigated systematically within the ranges of 0 - 50 GPa and 0 - 1000 K. The calculated results have been compared with available experimental and theoretical data.

description: Uridine-disphosphate glucuronosyl transferase (UGT) enzymes catalyze the formation of glucuronide conjugates of Phase II metabolism. Methods for absolute quantification of UGT1A1 and UGT1A6 were previously established utilizing stable isotope peptide internal standards with LC-MS/MS. The current method expands upon this by quantifying eight UGT1A isoforms by nanobore HPLC coupled with a linear ion trap-time of flight mass spectrometer platform. Recombinant enzyme digests of each of the isoforms were used to determine assay linearity and detection limits. Enzyme expression level in human liver, kidney and intestinal microsomal protein was determined by extrapolation from spiked stable isotope standards. Intraday and Interday variability was

description: Crowdsourcing is a process of accumulating the ideas, thoughts or information from many independent participants, with aim to find the best solution for a given challenge. Modern information technologies allow for massive number of subjects to be involved in a more or less spontaneous way. Still, the full potentials of crowdsourcing are yet to be reached. We introduce a modeling framework through which we study the effectiveness of crowdsourcing in relation to the level of collectivism in facing the problem. Our findings reveal an intricate relationship between the number of participants and the difficulty of the problem, indicating the optimal size of the crowdsourced group. We discuss our results in the context of modern utilization of crowdsourcing.
