description: Casimir effect in the planar setting is described using the boundary state formalism, for general partially reflecting boundaries. It is expressed in terms of the low-energy degrees of freedom, which provides a large distance expansion valid for general interacting field theories provided there is a non-vanishing mass gap. The expansion is written in terms of the scattering amplitudes, and needs no ultraviolet renormalization. We also discuss the case when the quantum field has a nontrivial vacuum configuration.

description: System I is a simply-typed lambda calculus with pairs, extended with an equational theory obtained from considering the type isomorphisms as equalities. In this work we propose an extension of System I to polymorphic types, adding the corresponding isomorphisms. We provide non-standard proofs of subject reduction and strong normalisation, extending those of System I.

description: Starting from a fully quantized Hamiltonian for an ensemble of identical emitters coupled to the modes of an optical cavity, we determine analytically regimes of thermal, collective anti-bunching and laser emission that depend explicitly on the number of emitters. The lasing regime is reached for a number of emitters above a critical number (which depends on the light-matter coupling, detuning and the dissipation rates) via a universal transition from thermal emission to collective anti-bunching to lasing as the pump increases. Cases where the second order intensity correlation fails to predict laser action are also presented.

The Stories of the Forced Sterilizations in Peru: The Power of Women’s Voices

description: This study explores the extent to which the implementation of the National Program for Reproductive Health and Family Planning by the Peruvian Government had consequences in the lives of women who underwent sterilizations. This study is based on a feminist methodology and used interviews as a method of data collection in order to privilege women’s voices and lived experiences from a gender perspective. It addresses notions of biopower and the concept of reproductive health within a framework of intersectionality. Finally, by linking women’s testimonies with the theoretical framework, it was possible to identify that specific Peruvian women, in vulnerable and poor conditions, were targeted by the Government because they did not represent the idea of development, and since then, women are dealing with physical, emotional, and social consequences.

description: Non-compensable cold exposure represents a potentially deadly threat to humans, as we lack highly specialized organs and mechanisms necessary to maintain our optimal core temperature of ~37°C. Repeated exposures to cold have been shown to induce protective physiological changes in cold responses through a process known as cold acclimatization (natural) or acclimation (in laboratory). The purpose of this thesis was to determine what physiological changes occur following an intense 7 day, 14°C cold water immersion acclimation protocol, during both non-compensable (Chapter 2) and compensable cold exposures (Chapter 3). This includes identifying changes in the contributions of the shivering (ST) and non-shivering (NST) thermogenic pathways to overall heat production. ST and NST changes were quantified via electromyography and indirect calorimetry, respectively. This 7 day cold water acclimation protocol resulted in a decrease in cooling rate, a significant increase in mean esophageal core temperature, a decrease in peak heart rate following immersion, and increased thermal comfort from day 1 to day 7 of the 1h 14°C cold water immersions. Further to these findings, changes in ST and NST were measured pre- and post-acclimation with a standardized compensable cold protocol using a liquid conditioned suit (LCS) which lowered Tskin to 26°C for 2.5h. The cold acclimation protocol resulted in a ~38% decrease in mean shivering over the 2.5h without any change in thermogenic rate from pre- to post-cold acclimation. In addition, no significant difference in fuel selection was observed. These results indicate that the short, intense cold acclimation protocol did result in a substantial change in the contribution of ST and NST to total heat production which could increase cold tolerance by reducing involuntary muscle contractions during ST.

description: We investigate the covariant formulation of Chern-Simons theories in a general odd dimension which can be obtained by introducing a vacuum connection field as a reference. Field equations, Noether currents and superpotentials are computed so that results are easily compared with the well-known results in dimension 3. Finally we use this covariant formulation of Chern-Simons theories to investigate their relation with topological BF theories.

Targeting protein folding in the malaria parasite
Creators: name: Wilkinson, Mark Dale
Publisher: name: Imperial College London
Year: 2020

description: The protein folding machinery in Plasmodium falciparum, the main causative agent of malaria disease, has been directly linked to emerging parasite drug resistance. The Chaperonin Containing TCP-1 ring (CCT) complex is the most up-regulated chaperonin in these drug resistant parasites and is therefore an attractive target to antagonize resistance in the field. Whilst there is a wealth of information about the CCT complex in higher eukaryotes, there is a paucity of information about the complex in more divergent species, such as the malaria parasite. The work presented in this thesis explores the CCT complex in P. falciparum (PfCCT) and the folding of its substrates, including the essential and abundant protein actin. First, I present a technique for studying actin on a single molecule level. Using this system, I observe the dynamic changes in actin’s macromolecular structure, its folding and drug-binding in real-time. To understand PfCCT, I biochemically char- acterise one of its essential cofactors, PhLP2, and isolate the complex from parasite lysate. I identify the PfCCT interactome and obtain a low-resolution structure of the complex, which has a highly conserved interactome and structure. Towards targeting the complex, I use a biosynthetic platform that expresses a puta- tive CCT-targeting compound, violacein, to conduct a high-throughput screen. I test the effect of violacein and biosynthetically-derived violacein derivatives on parasite growth. I show that violacein inhibits both wild type and drug-resistant parasite iso- lates from the field and identify a number of derivatives that are more potent than the parent compound. I show that violacein affects actin dynamics in vivo, resulting in an accumulation of actin signal indicative of incorrect protein folding, supporting the hypothesis that violacein targets the CCT complex. The work presented in this thesis provides a clear route for antimalarial drug development, ultimately towards targeting protein folding to stem the deadly disease.

description: Let $f(\mathbb{z},\bar{\mathbb{z}})$ be a convenient Newton non-degenerate mixed polynomial with strongly polar non-negative mixed weighted homogeneous face functions. We consider a convenient regular simplicial cone subdivision $Σ^*$ which is admissible for $f$ and take the toric modification $\hatπ : X \to \mathbb{C}^n$ associated with $Σ^*$. We show that the toric modification resolves topologically the singularity of the mixed hypersurface germ defined by $f(\mathbb{z},\bar{\mathbb{z}})$ under the Assumption (*) (Theorem 32). This result is an extension of the first part of Theorem 11 ([4]) by Mutsuo Oka. We also consider some typical examples (§9).

description: Ultracold gases in optical lattices are of great interest, because these systems bear a great potential for applications in quantum simulations and quantum information processing, in particular when using particles with a long-range dipole-dipole interaction, such as polar molecules. Here we show the preparation of a quantum state with exactly one molecule at each site of an optical lattice. The molecules are produced from an atomic Mott insulator with a density profile chosen such that the central region of the gas contains two atoms per lattice site. A Feshbach resonance is used to associate the atom pairs to molecules. Remaining atoms can be removed with blast light. The technique does not rely on the molecule-molecule interaction properties and is therefore applicable to many systems.

Statistical physics of the melting of inhomogeneous DNA

Year: 2008
Subjects: subject: Biological Physics (physics.bio-ph)
subject: FOS: Physical sciences

description: We studied how the inhomogeneity of a sequence affects the phase transition that takes place at DNA melting. Unlike previous works, which considered thermodynamic quantities averaged over many different inhomogeneous sequences, we focused on precise sequences and investigated the succession of local openings that lead to their dissociation. For this purpose, we performed Transfer Integral type calculations with two different dynamical models, namely the heterogeneous Dauxois-Peyrard-Bishop model and the model based on finite stacking enthalpies we recently proposed. It appears that, for both models, the essential effect of heterogeneity is to let different portions of the investigated sequences open at slightly different temperatures. Besides this macroscopic effect, the local aperture of each portion indeed turns out to be very similar to that of a homogeneous sequence with the same length. Rounding of each local opening transition is therefore merely a size effect. For the Dauxois-Peyrard-Bishop model, sequences with a few thousands base pairs are still far from the thermodynamic limit, so that it is inappropriate, for this model, to discuss the order of the transition associated with each local opening. In contrast, sequences with several hundreds to a few thousands base pairs are pretty close to the thermodynamic limit for the model we proposed. The temperature interval where power laws holds is consequently broad enough to enable the estimation of critical exponents. On the basis of the few examples we investigated, it seems that, for our model, disorder does not necessarily induce a decrease of the order of the transition.

It is found that such bound states exist for all possible values of c and within several nonoverlapping ranges (called bands) of η. The ranges of ηwithin each band can be determined completely using Farey sequences in number theory. We observe that N-body bound states appearing within each band can have both positive and negative values of the momentum and binding energy.

Sustainable economic development is an objective necessity for the further development of production relations in the world. It was emphasized the deepening of trade relations between Ukraine and the EU on the basis of the Free Trade Agreement. It is emphasized that one of the reasons for the crisis in rural areas of Ukraine is the monofunctional nature of rural development, the basis of which is agriculture. Important areas of the Rural Development Policy in Ukraine are the need for state support for the formation, accumulation and use of human capital in rural areas. It is proposed to develop a set of regional programs for the development of rural areas of Ukraine.

description: We deduce from Poincare's ellipsoidal wavefronts a relativistic Doppler-Fizeau formula that is not the same as 1905 Einstein's one. Longitudinally, Einstein's formula and Poincare's formula are the same. The question of an experimental test is connected with the possibility or the impossibility of directly measuring the relativistic transverse effect. Hasselkamp's 1978 experiment becomes a crucial experiment because Poincare's relativistic kinematics predicts an expansion of sapce directly connected with the Doppler-Fizeau effect for the remote objects.

Quantifying the trade-off between income stability and the number of members in a pooled annuity fund

Publisher: name: arXiv
Year: 2020
Subjects: subject: Risk Management (q-fin.RM)

description: The number of people who receive a stable income for life from a closed pooled annuity fund is studied. Income stability is defined as keeping the income within a specified tolerance of the initial income in a fixed proportion of future scenarios. The focus is on quantifying the effect of the number of members, which drives the level of idiosyncratic longevity risk in the fund, on the income stability. To do this, investment returns are held constant and systematic longevity risk is omitted. An analytical expression that closely approximates the number of fund members who receive a stable income is derived and is seen to be independent of the mortality model. An application of the result is to calculate the length of time for which the pooled annuity fund can provide the desired level of income stability

description: In the last 15 years a remarkable number of people working in the cultural field moved from Turkey to Berlin. Their motivations are various, but what can be analyzed is how those cul-tural agents arrive in Berlin. Visual artists are put in the focus of this research. It is their pre-carious situation that exposes struggles of identity and connected to this institutional failure. Considering political tensions, how can migration theories detangle the variables that make a living together possible? Based on empirical material that was collected in conversations with Turkish cultural agents in Germany and German cultural agents who live in Turkey the attempt was made to identify the power relations between the artist from another country and cultural institutions in Berlin.

description: The development of a market economy, instability of the external environment, reform of property relations, irrational distribution, inefficient use of available economic resources, exacerbation of contradictions in the development of productive forces and production relations highlight the need to increase the efficiency of enterprises. The issue of efficient use and reproduction of production and resource potential at the level of the agrosphere is widely covered in the economic literature. The severity of the problem of resource provision of agricultural production and the multi-vector solutions solve it in a number of leading in modern scientific research. The relevance of the study is due to the fact that the efficient and competitive operation of each individual agricultural enterprise is virtually impossible without quality and economically sound development of its production and resource potential.
An MPI messaging layer for network processors
Creators: name: Wijeyeratnam, Ashley
Publisher: name: University of British Columbia
Year: 2009

description: We describe the design and implementation of MPI-NP, a Myrinet communication system tailored to support LAM, a public domain version of MPI. The goals of MPI-NP are to reduce the time spent on the host for message processing, and to promote the overlap of computation and communication. MPI-NP achieves these goals by off-loading as much of the computation as possible to the network processor. MPI-NP relieves the host of several tasks, making more CPU cycles available to the application, but pays a price for heavy utilization of the slower network processor, by adding a significant overhead to message latency. Although part of the overhead can be attributed to the hardware of our testbed, the philosophy of MPI-NP characteristically does not provide the best latency possible because of performance disparities between host and network processors. Users are left with the choice of deciding on the trade-off of latency versus host overhead. Applications which are not latency bound can expect to perform well on MPI-NP.

description: The metal-insulator transition temperature in CMR manganites has been altered and brought close to the room temperature by preparing La$_{0.67}$Sr$_{0.33}$MnO$_{3}$ (LSMO)/ Nd$_{0.67}$Sr$_{0.33}$MnO$_{3}$ (NSMO) multilayers with ultra thin individual layers of LSMO and NSMO. The LSMO/NSMO multilayers with ultra thin individual layers of thickness of about $10Å$ exhibits 150% magnetoresistance at 270 K whereas LSMO/NSMO multilayers with moderate individual layer thickness of about $40Å$ each exhibits a mere 15% magnetoresistance at the same temperature. We have shown that the reduction in thickness of the individual layers leads to increased spin fluctuation which results in the enhancement of magnetoresistance.

description: A spatially oscillating pair potential $Δ(r)=Δ_0 e^{2i K\cdot r}$ with momentum $K>Δ_0/\hbar v$ drives a deconfinement transition of the Majorana bound states in the vortex cores of a Fu-Kane heterostructure (a 3D topological insulator with Fermi velocity $v$, on a superconducting substrate with gap $Δ_0$, in a perpendicular magnetic field). In the deconfined phase at zero chemical potential the Majorana fermions form a dispersionless Landau level, protected by chiral symmetry against broadening due to vortex scattering. The coherent superposition of electrons and holes in the Majorana Landau level is detectable as a local density of states oscillation with wave vector $\sqrt{K^2-(Δ_0/\hbar v)^2}$. The striped pattern also provides a means to measure the chirality of the Majorana fermions.

      polarization. These Kähler metrics induce a Hermitian metric
      on the relative canonical bundle of the family, whose

      which generalize the Weil-Petersson metric on the moduli

description: We present the results of an 850 micron JCMT/SCUBA survey for dust around 13 nearby solar mass stars. The dust mass sensitivity ranged from 0.005 to 0.16 Earth masses. Three sources were detected in the survey, one of which (HD 107146) has been previously reported. One of the other two submillimeter sources, HD 104860, was not detected by IRAS and is surrounded by a cold, massive dust disk with a dust temperature and mass of Tdust = 33 K and Mdust = 0.16 Mearth. The third source, HD 8907, was detected by IRAS and ISO at 60-87 microns, and has a dust temperature and mass Tdust = 48 K and Mdust = 0.036 Mearth. We find that the deduced masses and radii of the dust disks in our sample are roughly consistent with models for the collisional evolution of planetesimal disks with embedded planets. We also searched for residual gas in two of the three systems with detected submillimeter excesses and place limits on the mass of gas residing in these systems. When the properties measured for the detected excess sources are combined with the larger population of submillimeter excess sources from the literature, we find strong evidence that the mass in small grains declines significantly on a ~200 Myr timescale, approximately inversely with age. However, we also find that the characteristic dust radii of the population, obtained from the dust temperature of the excess and assuming blackbody grains, is uncorrelated with age. This is in contrast to self-stirred collisional models for debris disk evolution which predict a trend of radius increasing with age, t ~ R^3. The lack of agreement suggests that processes beyond self-stirring, such as giant planet formation, play a role in the evolutionary histories of planetesimal disks.

description: The geometry of fireballs in relativistic heavy ion collisions is approximated by a static box, which is infinite in two directions while finite in the other direction. The critical temperature of deconfinement phase transition is calculated explicitly in the MIT bag model at vanishing baryon density. It is found that the critical temperature shifts to a value higher than that in an unconstrained space.

Applications of single-qubit rotations in quantum public-key cryptography
Creators: name: Nikolopoulos, Georgios M.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We discuss cryptographic applications of single-qubit rotations from the perspective of trapdoor one-way functions and public-key encryption. In particular, we present an asymmetric cryptosystem whose security relies on fundamental principles of quantum physics. A quantum public key is used for the encryption of messages while decryption is possible by means of a classical private key only. The trapdoor one-way function underlying the proposed cryptosystem maps integer numbers to quantum states of a qubit and its inversion can be infeasible by virtue of the Holevo's theorem.

Quantum version of a generalized Monty Hall game and its possible applications to quantum secure communications

description: In this work we propose a quantum version of a generalized Monty Hall game, that is, one in which the parameters of the game are left free, and not fixed on its regular values. The developed quantum scheme is then used to study the expected payoff of the player, using both a separable and an entangled initial-state. In the two cases, the classical mixed-strategy payoff is recovered under certain conditions. Lastly, we extend our quantum scheme to include multiple independent players, and use this extension to sketch two possible application of the game mechanics to quantum networks, specifically, two validated, mult-party, key-distribution, quantum protocols.

description: Bezeichnend für die Konjunktur der
      Griechendarstellungen in der Frührennaissance ist ihr
      prominenter Anfangspunkt durch das Konzil von Ferrara/Florenz
      (1438/39) und die weite ikonographische Verbreitung,
      innerhalb eines verhältnismäßig kurzen Zeitraumes. Während
      sich die über Jahrhunderte tradierten Ikonographien von
      Sarazenen, Osmanen oder Zigeunern immer wieder an aktuelle
      Vorstellungen und Wahrnehmungen anpassen, erscheint die kurze
      Hochkonjunktur des byzantinischen Habitus nur auf wenige
      Typen und Motive gegründet, die direkt auf die Ereignisse
      38/39 rekurrieren. Dabei treffen künstlerische und höfische
      Ideale von Invention, Dekorativität und Prachtentfaltung sich
      in diesen Bildern mit politischen und humanistischen
      Hypothesen von Kontinuität, translatio und Machtanspruch. Die
      fremde Bildfigur ist einerseits Platzhalter für das schwer
      Darstellbare und andererseits Darstellung der Grenzen des
      Eigenen, die den Fremden zuweilen einschließen.
description: Characteristic for the Greeks
      representations in early Renaissance art is their prominent
      starting point by the Council of Ferrara/Florence (1438/39)
      and the wide dissemination of iconographies, within a
      relatively short period. In comparison to the centuries where
      the iconographies of Saracens, Ottomans, or gypsies where
      repeated and varied, the short boom of the Byzantine habitus
      appear established only to a few types and motifs that recur
      directly to the events of 38/39. In that representations of
      Greeks meet artistic and courtly ideals of invention,
      decorativeness and splendor in with political and humanist
      assumptions of continuity, translatio and claim to power. The
      exotic image figure is on the one Hand a placeholder for the
      mostly unknown antiquity, and on the other hand displayable
      representation of the borders of the own, which include the
      strangers sometimes.

description: It is shown that the theory of aplanatic two-mirror telescopes developed by Karl Schwarzschild in 1905 leads to the unified description both the prefocal and the postfocal systems. The class of surfaces in the ZEMAX optical program has been properly extended to ascertain the image quality in exact Schwarzschild aplanats. A comparison of Schwarzschild aplanats with approximate Ritchey-Chretien and Gregory-Maksutov aplanatic telescopes reveals a noticeable advantage of the former at fast focal ratio of the system.

description: Given a Stein manifold X of dimension n>1, a discrete sequence a_j in X, and a discrete sequence b_j in C^m where m > [3n/2], there exists a proper holomorphic embedding of X into C^m which sends a_j to b_j for every j=1,2,.... This is the interpolation version of the embedding theorem due to Eliashberg, Gromov and Schurmann. The dimension m cannot be lowered in general due to an example of Forster.
Reexamining $ B\to ππ,πK$ Decays in QCD Factorization Approach

description: Motivated by the recent experimental data, we have revisited the $B\to πK,ππ$ decays in the framework of QCD factorization, with inclusion of the important strong penguin corrections of order $α_s^2$ induced by $b\to D g^\ast g^\ast$ ($D=d$ or $s$ and $g^\ast$ denotes an off-shell gluon) transitions. We find that these higher order strong penguin contributions can provide $\sim 30%$ enhancement to the penguin-dominated $B\to πK$ decay rates, and such an enhancement can improve the consistency between the theoretical predictions and the experimental data significantly, while for the tree-dominated $B\to ππ$ decays, these higher order contributions play only a minor role. When these strong penguin contributions are summed, only a small strong phase remains and the direct CP asymmetries get small corrections. We also find patterns of the ratios between the CP-averaged branching fractions remain nearly unaffected even after including these higher order corrections and the $πK$ puzzle still persists. Our results may indicate that to resolve the puzzle one would have to resort to new physics contributions in the electroweak penguin sector as found by Buras {\it et al}.

One loop gluon form factor and freezing of alpha_s in the Gribov-Zwanziger QCD Lagrangian

description: We use the Gribov-Zwanziger Lagrangian in QCD to evaluate the one loop correction to the gluon propagator as a function of the Gribov volume and verify that the propagator vanishes in the infrared limit. Using the corresponding correction to the Faddeev-Popov ghost propagator we construct the renormalization group invariant coupling constant, alpha^eff_S(p^2), from the gluon and ghost form factors and verify, using the Gribov mass gap condition, that it freezes out at zero momentum to a non-zero value. This is qualitatively consistent with other approaches. We also show that there is an enhancement of the propagator of one of the Zwanziger ghosts at two loops similar to that which occurs for the Faddeev-Popov ghosts. From the exact evaluation of the form factors we examine power corrections for the gluon propagator and the effective coupling. We find that both have the same qualitative behaviour in that the leading power correction is O(1/p^2) and not O(1/(p^2)^2).
