description: For the high luminosity upgrade of the LHC at CERN, ATLAS is considering the addition of a High Granularity Timing Detector (HGTD) in front of the end cap and forward calorimeters at |z| = 3.5 m and covering the region 2.4 < |η| < 4 to help reducing the effect of pile-up. The chosen sensors are arrays of 50 μm thin Low Gain Avalanche Detectors (LGAD). This paper presents results on single LGAD sensors with a surface area of 1.3x1.3 mm2 and arrays with 2x2 pads with a surface area of 2x2 mm^2 or 3x3 mm^2 each and different implant doses of the p+ multiplication layer. They are obtained from data collected during a beam test campaign in Autumn 2016 with a pion beam of 120 GeV energy at the CERN SPS. In addition to several quantities measured inclusively for each pad, the gain, efficiency and time resolution have been estimated as a function of the position of the incident particle inside the pad by using a beam telescope with a position resolution of few μm. Different methods to measure the time resolution are compared, yielding consistent results. The sensors with a surface area of 1.3x1.3 mm^2 have a time resolution of about 40 ps for a gain of 20 and of about 27 ps for a gain of 50 and fulfill the HGTD requirements. Larger sensors have, as expected, a degraded time resolution. All sensors show very good efficiency and time resolution uniformity.

description: The observed replication of fermions in three families is undoubtedly a reflection of a deeper symmetry underlying the standard model. In this paper we investigate one very elementary possibility, that physics above the grand unification scale is described by the symmetry group $G\timesSU(3)_{fam}$ with $G$ a gauged grand unified group, and $SU(3)_{fam}$ a global family symmetry. The breaking of this symmetry at the GUT scale produces global texture, providing a mechanism for structure formation in the universe, and sets strong constraints on the low energy fermion mass matrix. With the addition of a ${\bf 45}$ Higgs and certain assumptions about the relative strength of Higgs couplings, the simplest $SU(5)$ theory yields an eight parameter form for the fermion mass matrices, which we show is consistent with the thirteen observable masses and mixing angles. We discuss the natural suppression of flavour changing neutral currents (FCNCs) and emphasise the rich low energy Higgs sector. With minor assumptions, the theory unifies consistently with the recent LEP data. We consider the extension to $G=SO(10)$, where some simplification and further predictiveness emerges. Finally we discuss the dynamics of $SU(3)_{fam}$ texture and show that the known constraints on unification `predict' a GUT symmetry breaking scale of the order required for cosmic structure formation, and by the recent detection of cosmic microwave anisotropy by COBE.

description: The variety of the phase transitions in Induced QCD are studied. Depending upon the parameters in the scalar field potential, there could be infinite number of fixed points, with different critical behavior. The integral equation for the density of the eigenvalues of the scalar field are generalized to the weak coupling phases, with the gap at the origin. We find a wide class of the massive solutions of these integral equations in the strong coupling phases, and derive an explicit eigenvalue equation for the scalar branch of the mass spectrum.

description: We investigate the population of dwarf galaxies with stellar masses similar to the Large Magellanic Cloud (LMC) and M33 in the EAGLE galaxy formation simulation. In the field, galaxies reside in haloes with stellar-to-halo mass ratios of $1.03^{+0.50}_{-0.31}\times10^{-2}$ (68% confidence level); systems like the LMC, which have an SMC-mass satellite, reside in haloes about 1.3 times more massive, which suggests an LMC halo mass at infall, $M_{200}=3.4^{+1.8}_{-1.2}\times10^{11}M_\odot$ (68% confidence level). The colour distribution of dwarfs is bimodal, with the red galaxies ($g-r>0.6$) being mostly satellites. The fraction of red LMC-mass dwarfs is 15% for centrals, and for satellites this fraction increases rapidly with host mass: from 10% for satellites of Milky Way (MW)-mass haloes to nearly 90% for satellites of groups and clusters. The quenching timescale, defined as the time after infall when half of the satellites have acquired red colours, decreases with host mass from ${>}5$ Gyrs for MW-mass hosts to $2.5$ Gyrs for cluster mass hosts. The satellites of MW-mass haloes have higher star formation rates and bluer colours than field galaxies. This is due to enhanced star formation triggered by gas compression shortly after accretion. Both the LMC and M33 have enhanced recent star formation that could be a manifestation of this process. After infall into their MW-mass hosts, the $g-r$ colours of LMC-mass dwarfs become bluer for the first 2 Gyrs, after which they rapidly redden. LMC-mass dwarfs fell into their MW-mass hosts only relatively recently, with more than half having an infall time of less than 3.5 Gyrs.

These processes are important tests for the non-abelian gauge sector of the standard model (SM). Precise calculations of these processes can therefore probe the anomalous gauge-boson interactions. Besides, these processes are important potential backgrounds for the intermediate mass Higgs (IMH) search in the $eγ\rightarrow WHν$ production.

description: We consider the energy transfer process between two identical atoms placed inside a perfectly conducting cylindrical waveguide. We first introduce a general analytical expression of the energy transfer amplitude in terms of the electromagnetic Green's tensor; we then evaluate it in the case of a cylindrical waveguide made of a perfect conductor, for which analytical forms of the Green's tensor exist. We numerically analyse the energy transfer amplitude when the radius of the waveguide is such that the transition frequency of both atoms is below the lower cutoff frequency of the waveguide, so that the resonant photon exchange is strongly suppressed. We consider both cases of atomic dipoles parallel and orthogonal to the axis of the guide. In both cases, we find that the energy transfer is modified by the presence of the waveguide. In the near zone, that is when the atomic separation is smaller than the atomic transition wavelength, the change, with respect to the free-space case, is small for axial dipoles, while it is larger for radial dipoles; it grows when the intermediate region between near and far zone is approached. In the far zone, we find that the energy transfer amplitude is strongly suppressed by the waveguide, becoming virtually zero. A physical interpretation of these results is discussed. Finally, we discuss the resonance interaction energy and force between two identical correlated atoms in the waveguide, one excited and the other in the ground state, prepared in their symmetric or antisymmetric superposition.

description: Purpose: The purpose of this qualitative phenomenological study is to explore the of self-initiated expatriates prior to and during acculturation to life in a smaller periphery region such as Vorarlberg, Austria. By providing insights into their lived experience this research aims to fill in the gaps of missing information on motivators, success factors to adjustment, issues, and stressors, and more that SIEs experience when adjusting. Specifically, what items promote adjustment and what items hinder adjustment. Findings: Developed a better understanding of how and what motivational factors lead to expatriation. Furthermore, that opportunities arise by chance. During acculturation, language factors (dialect), cultural differences act as stressors. While social support, and organizational support, learning of the language act as promoters of acculturation. Further Research could be done including ethnicities, SIEs moving from developed to developing countries, adjustment in regions with dialect vs no dialect. Key words: self-initiated expatriates, expatriation, acculturation, adjustment, promoting acculturation, hindering acculturation.

description: Nodal-loop semimetals are materials in which the conduction and valence bands cross on a one-dimensional loop in the reciprocal space. For the nodal-loop character to manifest in physical properties, it is desired that the loop is close to the Fermi level, relatively flat in energy, simple in its shape, and not coexisting with other extraneous bands. Here, based on the first-principles calculations, we show that the monoclinic CuTeO$_3$ is a realistic nodal-loop semimetal that satisfies all these requirements. The material features only a single nodal loop around the Fermi level, protected by either of the two independent symmetries: the $\mathcal{PT}$ symmetry and the glide mirror symmetry. The size of the loop can be effectively tuned by strain, and the loop can even be annihilated under stain, making a topological phase transition to a trivial insulator phase. Including the spin-orbit coupling opens a tiny gap at the loop, and the system becomes a $\mathbb{Z}_2$ topological semimetal with a nontrivial bulk $\mathbb{Z}_2$ invariant but no global bandgap. The corresponding topological surface states have been identified. We also construct a low-energy effective model to describe the nodal loop and the effect of spin-orbit coupling.

description: We employ computer simulations to unveil the translational and rotational dynamics of the self-driven chemically symmetric and asymmetric rigid dumbbells in two-dimensional polymer gel. Our results show that activity or the self-propulsion always enhances the dynamics of the dumbbells. Making the self-propelled dumbbell chemically asymmetric leads to further enhancement in dynamics. Additionally, the direction of self-propulsion is a key factor for the chemically asymmetric dumbbells, where self-propulsion towards the non-sticky half of the dumbbell results in faster translational and rotational dynamics compare to the case with the self-propulsion towards the sticky half of the dumbbell. Our analyses show that both the symmetric and asymmetric passive rigid dumbbells get trapped inside the mesh of the polymer gel, but the chemical asymmetry always facilitates mesh to mesh motion of the dumbbell and it is even more pronounced when the dumbbell is self-propelled. This results multiple peaks in the van Hove function with increasing self-propulsion. In a nutshell, we believe that our in silico study can guide the researchers design efficient artificial microswimmers possessing potential applications in site-specific delivery.

description: It is proved that for a system of spins $σ_i = \pm 1$ having an interaction energy $-\sum K_{ij} σ_i σ_j $ with all the $K_{ij}$ strictly positive,one can construct a dual formulation by associating a dual spin $S_{ijk} = \pm 1$ to each triplet of distinct sites $i,j$ and $k$. The dual interaction energy reads $-\sum _{(ij)} D_{ij} \prod _{k \neq i,j} S_{ijk}$ with $tanh(K_{ij})\ = \ exp(-2D_{ij})$, and it is invariant under local symmetries. We discuss the gauge-fixing procedure, identities relating averages of order and disorder variables and representations of various quantities as integrals over Grassmann variables. The relevance of these results for Polyakov's approach of the 3D Ising model is briefly discussed.

description: Turkey has a total population of 82 million 3 thousand 882 in 2018. Rural population is 6 million 337 thousand 385 and 7.7% of our population. Contribution to the agricultural economy and rural population in Turkey's economy plays a primary role. Demographic projection is a method to help us prepare prudential economic and social policies. These projections provide useful predictions about, current population structure, it’s vocations and also helps us to determine if the current behaviour of the population keeps having the same vocation, what kind of population would appear in near future, population density, migrations, sex and age pattern of the population and sociocultural changes. Demographic Projections not only suggest that Turkey’s young and constantly growing population pattern is changing but it also shows that it's fertility rates and structures showing some changes as well. Changes through Low Death and Fertilty Rates from higher rates ,what we can define as “Demographic Change Process”, affects on population’s age structure as well. What we gathered from recent projection researchs indicates that there will be constant fall on young population levels, there will be rise in the number of population in working till 2040 but then there will be fall on the number in the same population group afterwards. Based on these informations, elderly population in Turkey constantly growing. These changes on both age and demographic structures makes impact in direct or indirect ways on both Social and Ekonomic live in Turkey. Demographic changes brought some positive outcomes(having a peak on population in working age level) along with the risks that Turkey never have been faced before(aging population). This situation requires taking measures for many sectors, especially the agricultural economy. Therefore, our study of the demographic transformation of Turkey, the rural population and population projections to 2080 are analyzed.

description: The full quark-gluon vertex is a crucial ingredient for the dynamical generation of a constituent quark mass from the standard quark gap equation, and its non-transverse part may be determined exactly from the nonlinear Slavnov-Taylor identity that it satisfies. The resulting expression involves not only the quark propagator, but also the ghost dressing function and the quark-ghost kernel, and constitutes the non-abelian extension of the so-called "Ball-Chiu vertex", known from QED. In the present work we carry out a detailed study of the impact of this vertex on the gap equation and the quark masses generated from it, putting particular emphasis on the contributions directly related with the ghost sector of the theory, and especially the quark-ghost kernel. In particular, we set up and solve the coupled system of six equations that determine the four form factors of the latter kernel and the two typical Dirac structures composing the quark propagator. Due to the incomplete implementation of the multiplicative renormalizability at the level of the gap equation, the correct anomalous dimension of the quark mass is recovered through the inclusion of a certain function, whose ultraviolet behavior is fixed, but its infrared completion is unknown; three particular Ansätze for this function are considered, and their effect on the quark mass and the pion decay constant is explored. The main results of this study indicate that the numerical impact of the quark-ghost kernel is considerable; the transition from a tree-level kernel to the one computed here leads to a $20\%$ increase in the value of the quark mass at the origin. Particularly interesting is the contribution of the fourth Ball-Chiu form factor, which, contrary to the abelian case, is nonvanishing, and accounts for $10\%$ of the total constituent quark mass.

description: Fiber amplifiers with high power and high pulse energy are strongly in demand for both scientific research and industrial applications. Ytterbium-doped fiber has been an outstanding choice for its broad-gain bandwidth and excellent power conversion efficiencies. In this dissertation, we introduced a compact high power high pulsed energy laser system with chirally coupled core (3C) Yb-doped fibers as the gain media. Traditional standard fibers and photonic crystal fibers are not suitable for compact high power high pulse energy laser systems because of poor higher order modes (HOMs) management and complicated air-hole structure. Newly invented 3C silica fibers solve these problems. A helical side-core around the Yb-doped central core extracts the HOMs from the central core. By adjusting this chirally structure, the core of the 3C fiber can be enlarged and the transverse mode of the fiber can be single mode at certain wavelengths. To simulate the amplification process with high power high pulse energy better, a new modeling method based on a combination of the rate equations and the nonlinear Schrödinger equations is invented. The gain was calculated from rate equations and the pulse evolution was analyzed using nonlinear Schrödinger equation. The simulation provided a good guidance for building compact high power high pulse energy laser systems. To achieve high power and high pulse energy, the system is designed as a two-stage structure.

description: Entrepreneurship is the force that drives economic, social and technical progress. A small percentage of firms (5%) is responsible for a disproportionately large amount of net job creation (>50%). Named high growth firms, these successful enterprises have been in the spotlight of research looking into the key drivers of firm growth and growth policy. This dissertation explores high growth from multiple perspectives: at the level of the firm, by understanding how the definition of a high growth firm impacts its characteristics and expected performance over time; at the local level, by isolating the effect of political connections of firm performance and firm entry; and at the macro level, by observing the evolution of entrepreneurship during transition. The first study finds that most HGFs are unable to maintain high growth rates for long, but do register lower volatility in growth rates and a higher chance of survival. Results on growth volatility and persistence vary significantly with the specific definition of “high growth” used as well as with the specific variable used to measure growth (e.g., revenue, employees, profit, productivity). These findings have direct implications for growth policies and programs that depend on identifying HGFs. The second study indicates a strong significant effect of political alignment on revenue growth and firm entry. Larger firms take advantage of political connections for performance gains, while small firms are negatively impacted. Furthermore, alignment reduces entry into entrepreneurship by 8-11%. These findings establish political alignment and local-level business-politics collusion as important dynamics to consider when evaluating entrepreneurship policy in developing countries. The third study describes the interdependence between entrepreneurship, institutions, and transitions. The case of Romania shows that the beginning of transition was characterized by an initial explosion of newly created private enterprises, followed by a declining trend in enterprise creation and, recently, by a new increase in entrepreneurship activity. To conclude, this work contributes new perspectives towards a better understanding of high growth firms and growth policy. Policy implications are targeted towards transition and developing economies that have seen little representation in literature. The goal is to enable successful high growth policies across multiple levels.
Short-lived radioisotopes in meteorites from Galactic-scale correlated star formation

description: Meteoritic evidence shows that the Solar system at birth contained significant quantities of short-lived radioisotopes (SLRs) such as 60Fe and 26Al (with half-lives of 2.6 and 0.7 Myr respectively) produced in supernova explosions and in the Wolf-Rayet winds that precede them. Proposed explanations for the high SLR abundance include formation of the Sun in a supernova-triggered collapse or in a giant molecular cloud (GMC) that was massive enough to survive multiple supernovae (SNe) and confine their ejecta. However, the former scenario is possible only if the Sun is a rare outlier among massive stars, while the latter appears to be inconsistent with the observation that 26Al is distributed with a scale height significantly larger than GMCs. In this paper, we present a high-resolution chemo-hydrodynamical simulation of the entire Milky-Way Galaxy, including stochastic star formation, HII regions, SNe, and element injection, that allows us to measure for the distribution of 60Fe/56Fe and 26Al/27Al ratios over all stars in the Galaxy. We show that the Solar System's abundance ratios are well within the normal range, but that SLRs originate neither from triggering nor from confinement in long-lived clouds as previously conjectured. Instead, we find that SLRs are abundant in newborn stars because star formation is correlated on galactic scales, so that ejecta preferentially enrich atomic gas that will subsequently be accreted onto existing GMCs or will form new ones. Thus new generations of stars preferentially form in patches of the Galaxy contaminated by previous generations of stellar winds and supernovae.

Waiting for Asian Canada: Fred Wah's Transnational Aesthetics
Creators: name: Yu, Timothy

Year: 2016

description: Fred Wah's 1985 Waiting for Saskatchewan offers a snapshot of the emergence of an Asian Canadian aesthetic, providing a genealogy that positions Asian Canadian writing at the nexus of transnational flows from China, Japan, and the United States, while also emphasizing the cross-ethnic coalitions that give rise to the category of the Asian Canadian in the 1970s and 1980s. Waiting for Saskatchewan offers a complex constellation of Chinese content, Japanese forms, and U.S. aesthetic mediation that nonetheless takes as its “centre” a small Canadian prairie town. The forms of Waiting, from Olsonian projective poetics to the Japanese haibun, reveal Asian Canada as a process of transnational convergence, a dialogic space that is always being rewritten across national borders.

From the Sacred to the Sacrificial Landscape: Reading and Resisting Settler-Canadian Environmental Discourse in M.T. Kelly’s A Dream Like Mine and the Navigation Protection Act
Creators: name: Stevenson, Shaun Alexander
Publisher: name: Canadian Literature
Year: 2017

description: This paper explores how the Canadian landscape is figured through two interrelated processes of settler colonialism, which form social and subjective identities in relation to Canadian environmental discourse. I explore these processes through what I refer to as settler sanctified and sacrificed landscapes. I read this dual process of settler sanctification and sacrifice through a literary representation in M.T. Kelly’s 1987 novel, A Dream Like Mine, exploring the operation of contemporary settler liberal environmentalism in a self-conscious settler narrative, and through Canadian environmental policy, which expresses the preemptive sanctification of the settler landscape present in Canada’s oldest piece of environmental legislation, the recently amended Navigation Protection Act. My readings of these two seemingly disparate texts aim to illustrate that a particular kind of sanctification of the landscape has structured settler-Canadian engagement with the environment from the very inception of official Canadian environmental discourse, thus creating the conditions for the landscapes’ inevitable sacrifice.

description: We present a preliminary calculation of B_K using domain-wall valence quarks and 2+1 flavors of improved staggered sea quarks. Both the size of the residual quark mass, which measures the amount of chiral symmetry breaking, and of the mixed meson splitting Delta_mix, a measure of taste-symmetry breaking, show that discretization effects are under control in our mixed action lattice simulations. We show preliminary data for pseudoscalar meson masses, decay constants and B_K. We discuss general issues associated with the chiral extrapolation of lattice data, and, as an example, present a preliminary chiral and continuum extrapolation of f_pi. The quality of our data shows that the good chiral properties of domain-wall quarks, in combination with the light sea quark masses and multiple lattice spacings available with the MILC staggered configurations, will allow for a precise determination of B_K.

description: The Casimir energy for the classically stable configurations of the topological solitons in 2D quantum antiferromagnets is studied by performing the path-integral over quantum fluctuations. The magnon fluctuation around the solitons saturating the Bogomol'nyi inequality may be viewed as a charged scalar field coupled with an effective magnetic field induced by the solitons. The magnon-soliton couping is closely related to the Pauli Hamiltonian, with which the effective action is calculated by adapting the worldline formulation of the derivative expansion for the 2+1d quantum electrodynamics in an external field. The resulting framework is more flexible than the conventional scattering analysis based on the Dashen-Hasslacher-Neveu formula. We obtain a short-range attractive well and a universal long-range $1/r$-type repulsive potential between two solitons.

description: The correlations of certain entangled quantum states can be fully reproduced via a local model. We discuss in detail the practical implementation of an algorithm for constructing local models for entangled states, recently introduced by Hirsch et al. [Phys. Rev. Lett. 117, 190402 (2016)] and Cavalcanti et al. [Phys. Rev. Lett. 117, 190401 (2016)]. The method allows one to construct both local hidden state (LHS) and local hidden variable (LHV) models, and can be applied to arbitrary entangled states in principle. Here we develop an improved implementation of the algorithm, discussing the optimization of the free parameters. For the case of two-qubit states, we design a ready-to-use optimized procedure. This allows us to construct LHS models (for projective measurements) that are almost optimal, as we show for Bell diagonal states, for which the optimal model has recently been derived. Finally, we show how to construct fully analytical local models, based on the output of the convex optimization procedure.

"the absolute / of water": The Submarine Poetic of M. NourbeSe Philip’s Zong!
Creators: name: Siklosi, Kate Mary Beth
Publisher: name: Canadian Literature
Year: 2017

description: Despite its status as ahistorical in metanarratives of modernity that serve the colonial project, the sea nonetheless features as a prominent and dynamic space in the global (and especially Western) historical imaginary. In M. NourbeSe Philip’s 2008 long poem Zong!, the seascape features as a kinetic contact zone of modernity by creating a responsive archive that documents and preserves the cultural and historical agency of colonized subjects. This paper examines Philip’s text from the perspective of two related spatial schemas that stand in opposition to land-locked narratives of Western modernity: Kamau Brathwaite’s tidalectics, and Katherine McKittrick’s (via Sylvia Wynter) demonic grounds. Bringing these two lenses together in conversation with Philip’s text highlights the oppositional archive of space and being engendered by Zong!’s resistant maritime poetic.

High Density Polymer Modification of Proteins Using Polymer - Based Protein Engineering
Creators: name: Cummings, Chad S.

Subjects: subject: 90399 Biomedical Engineering not elsewhere classified

description: Proteins and protein-based materials are used for a wide range of therapeutic, diagnostic, and biotechnological applications. Still, the inherent instability of proteins in non-native environments greatly limits the applications in which they are effective. In order to increase their utility, proteins are often modified, either biologically or chemically, to manipulate their bioactivity and stability profiles. In this work, covalent attachment of polymers to the enzyme chymotrypsin was used to predictably tailor protein bioactivity and stability. Specifically, atom transfer radical polymerization (ATRP) based polymer-based protein engineering (PBPE) was used to grow polymers directly from the surface of chymotrypsin. First, the temperature responsive polymers poly(N-isopropyl acrylamide) (pNIPAM), which has a lower critical solution temperature (LCST) and poly(dimethylamino propane sulfonate) (pDMAPS), which has an upper critical solution temperature (UCST), were separately grown from chymotrypsin. The temperature responsive properties of the polymers were conserved in the protein-polymer conjugates, and chymotrypsin bioactivity, productivity, and substrate specificity were predictably tailored at different temperatures depending on the structural organization of the polymers. Next, a dual block polymer-chymotrypsin conjugate was synthesized by growing poly(sulfobetaine methacrylamide) (pSBAm)-block-pNIPAm conjugates from the surface of chymotrypsin. The CT-pSBAm-b-pNIPAm conjugates showed temperature dependent kinetics, due to UCST or LCST driven polymer collapse at high and low temperature. Most interestingly, the dual block conjugates were dramatically more stable than native chymotrypsin to low pH. In order to further investigate the effect of polymer conjugation on chymotrypsin stability at low pH, four distinct and uniquely charged polymers were grown from the surface of chymotrypsin. With these new conjugates, we confirmed that chymotrypsin low pH stability was dependent on the chemical structure of polymers covalently attached to chymotrypsin. Indeed, positively charged polymers stabilized chymotrypsin to low pH, but negatively charged and amphiphilic polymers destabilized the enzyme. Lastly, after developing strategies for low pH stabilization, new protein-polymer conjugates with the chemical permeation enhancer 1-phenylpiperazine were designed to enable protein transport across the intestinal epithelium. Bovine serum albumin-poly(oligoethylene methacrylate)-block-poly(phenylpiperazine acrylamide) BSA-pOEGMA-b-pPPZ conjugates induced dose dependent increases in Caco-2 monolayer permeability and transported across an in vitro intestinal monolayer model with low cell toxicity.
‘It is life you must write about’: Fixity and Refraction in Dionne Brand’s A Map to the Door of No Return: Notes to Belonging
Creators: name: Cranston-Reimer, Sharlee
Publisher: name: Canadian Literature
Year: 2017

description: Though many discussions of diaspora emphasize metaphors of mobility, Brand’s Map to the Door of No Return: Notes to Belonging uses moments of fixity and excess to think through the epistemological and embodied effects of the history and ongoing effects of slavery and to challenge the limitations of dominant readings of these approaches. To make this argument, I read Map in relation to auto/biography studies to see the parallel ways in which it emphasizes the importance of “illegitimate” sites of knowledge, but I then move to emphasize the moments that the text exceeds the genre of auto/biography when Brand moves to write about larger scale histories and memories to which she would not have literal access, but to which she certainly has experiential access. Relatedly, I consider the ways that the text uses fixity to emphasize how histories are written on the body, whether they were directly experienced or not.

Determining the best classifier for predicting the value of a boolean field on a blood donor database using genetic algorithms
Creators: name: Maiti, Ritabrata

Subjects: subject: Machine Learning (stat.ML)
subject: Machine Learning (cs.LG)

description: Motivation: Thanks to digitization, we often have access to large databases, consisting of various fields of information, ranging from numbers to texts and even boolean values. Such databases lend themselves especially well to machine learning, classification and big data analysis tasks. We are able to train classifiers, using already existing data and use them for predicting the values of a certain field, given that we have information regarding the other fields. Most specifically, in this study, we look at the Electronic Health Records (EHRs) that are compiled by hospitals. These EHRs are convenient means of accessing data of individual patients, but there processing as a whole still remains a task. However, EHRs that are composed of coherent, well-tabulated structures lend themselves quite well to the application to machine language, via the usage of classifiers. In this study, we look at a Blood Transfusion Service Center Data Set (Data taken from the Blood Transfusion Service Center in Hsin-Chu City in Taiwan). We used scikit-learn machine learning in python. From Support Vector Machines(SVM), we use Support Vector Classification(SVC), from the linear model we import Perceptron. We also used the K.neighborsclassifier and the decision tree classifiers. Furthermore, we use the TPOT library to find an optimized pipeline using genetic algorithms. Using the above classifiers, we score each one of them using k fold cross-validation. Contact: ritabratamaiti@hiretrex.com GitHub Repository: https://github.com/ritabratamaiti/Blooddonorprediction

description: Leptonic flavor-changing $H^0$ decays with branching ratios of the order of $10^{-5}-10^{-6}$ may constitute an interesting framework when looking for large $CP$-violating effects. We show that leptonic $CP$~asymmetries of an intermediate $H^0$ boson can be fairly large in natural scenarios of the minimal Standard Model ($SM$) with right-handed neutrinos, at a level that may be probed at future $H^0$~factories.
