description: Biological cells estimate concentration gradients of signaling molecules with a precision that is limited not only by sensing noise, but additionally by the cell's own stochastic motion. We ask for the theoretical limits of gradient estimation in the presence of both motility and sensing noise. We introduce a minimal model of a stationary chemotactic agent in the plane subject to rotational diffusion, which uses Bayesian estimation to optimally infer a gradient direction from noisy concentration measurements. Contrary to the known case of gradient sensing by temporal comparison, we show that for spatial comparison, the ultimate precision of gradient sensing scales not with the rotational diffusion time, but with its square-root. To achieve this precision, an individual agent needs to know its own rotational diffusion coefficient. This agent can accurately estimate the expected variability within an ensemble of agents. If an agent, however, does not account for its own motility noise, Bayesian estimation fails in a characteristic manner.

description: Io, the most volcanically active body in the solar system, loses heat through eruptions of hot lava. Heat is supplied by tidal heating and is thought to be transferred through the mantle by magmatic segregation, a mode of transport that sets it apart from convecting terrestrial planets. We present a model that couples magmatic transport of tidal heat to the volcanic system in the crust, in order to determine the controls on crustal thickness, magmatic intrusions, and eruption rates. We demonstrate that magmatic intrusions are a key component of Io's crustal heat balance; around 80% of the magma delivered to the base of the crust must be emplaced and frozen as plutons to match rough estimates of crustal thickness. As magma ascends from a partially molten mantle into the crust, a decompacting boundary layer forms, which can explain inferred observations of a high-melt-fraction region.

description: A general equilibrium simultaneous equation model is constructed to analyse the impacts of monetary policy on the maize and beef sectors of South Africa. The model is estimated by three-stage least squares and used to simulate the dynamic impacts of an expansionary monetary policy (15 percent increase in money supply) from 1975 to 1987. In the short run, this causes real interest rates to fall, real income to rise, exchange rate to depreciate and prices to rise. Rising real incomes cause beef demand to increase and human maize consumption to fall. Depreciation of the exchange rate and higher domestic inflation raise real input prices. This impacts negatively on maize and beef supply. Higher beef prices encourage beef production, which causes animal maize demand to increase. Lower real interest rates impact positively on maize supply, negatively on beef supply, and stimulate real agricultural investment. The net effect is a decline in real gross farm income in the maize and beef sectors of South Africa.
The role of symmetry in the short-time critical dymamics

description: We show that the short-time critical exponent $θ$ related to the critical initial slip in a stochastic model can be determined by the time correlation of the order parameter. In our procedure it suffices to start with an uncorrelated state with zero order parameter instead of departing, as usually done, from an initial state with a nonzero order parameter. The proof uses the group of symmetry operations related to the Markovian dynamics. Our scheme is extended to cover models with absorbing states.

description: Using data from the Large Area X-ray Proportional Counter (LAXPC) on the \textit{AstroSat} satellite, we observed the Type-1 thermonuclear X-ray bursts from the Low Mass X-ray Binary Neutron Star 4U 1323-62. The observations of 4U 1323-62 were carried out during the performance verification phase of the \textit{AstroSat} satellite showed six thermonuclear X-ray bursts in a total effective exposure of $\sim$ 49.5 ks for about two consecutive days. Recurrence time of the detected thermonuclear bursts is in accordance with the orbital period of the source $\sim$ 9400 seconds. Moreover, the light curve of 4U 1323-62 revealed the presence of two dips. We presented the results from time-resolved spectroscopy performed during all of the six X-ray bursts and also report the detection of a known low frequency Quasi-periodic oscillation (LFQPO) at $\sim$ 1 Hz, from the source. However, any evidence of kilohertz QPO was not found. We have shown the burst profile at different energy ranges. Assuming a distance of 10 kpc, we observed a mean flux $\sim$ 1.8 $\times$ $10^{-9}$ erg $cm^2$ $s^{-1}$. The radius of the blackbody is found to be highly consistent with the blackbody temperature and the blackbody flux of the bursts.

Photoemission spectra using synchrotron radiation reveal a hitherto unnoticed polarization dependence of the photoemission matrix elements for the surface component leading to a substantial suppression of its intensity. Bulk spectra extracted with the help of experimentally determined electron escape depth and estimated suppression of surface contributions resolve outstanding puzzles concerning the electronic structure in Ca1-xSrxVO3.

description: Green Marketing is among the contemporary issues in the field of Marketing. While many studies have been done in this field elsewhere, little studies have been conducted in Tanzania. Thus, this study aimed at identifying the level of green marketing adoption among agro-processing businesses in the context of Tanzania and studying the influence of business size on green marketing adoption. Data were collected from 120 micro, small and medium enterprises operating in agro-processing sector in Morogoro region. The findings show that, the level of adoption of green marketing practices is low as most businesses adopted relatively few practices. Also, it was found that, there is an association between business size and level of adoption of green marketing practices. It has to be noted that, the findings are limited to agro processing industry in Morogoro since the applicability of these findings to other industries is uncertain as data were collected in agro-processing industry.

description: Even at the beginning of the 21th century, hunger and malnutrition are still serious problems for many countries in the world. It is estimated that every three and a half seconds a person dies because of insufficient amount of food. There are as much as 925 million undernourished people on our planet. Hunger and malnutrition present in fact a great risk to the health worldwide, even greater than AIDS, malaria and tuberculosis altogether. Eastern Europe and Central Asia are both regions with specific conditions and issues related to the poorer part of the population. The goal of this paper is to point out possible solutions for eradication of extreme poverty with specific focus on these two regions and to highlight the most important factors that have had an influence on the development of the agricultural sector in these regions.

description: We study a special class of four-point correlation functions of infinitely heavy half-BPS operators in planar N=4 SYM which admit factorization into a product of two octagon form factors. We demonstrate that these functions satisfy a system of nonlinear integro-differential equations which are powerful enough to fully determine their dependence on the 't Hooft coupling and two cross ratios. At weak coupling, solution to these equations yields a known series representation of the octagon in terms of ladder integrals. At strong coupling, we develop a systematic expansion of the octagon in the inverse powers of the coupling constant and calculate accompanying expansion coefficients analytically. We examine the strong coupling expansion of the correlation function in various kinematical regions and observe a perfect agreement both with the expected asymptotic behavior dictated by the OPE and with results of numerical evaluation. We find that, surprisingly enough, the strong coupling expansion is Borel summable. Applying the Borel-Pade summation method, we show that the strong coupling expansion correctly describes the correlation function over a wide region of the 't Hooft coupling.

Throughput Optimal Decentralized Scheduling with Single-bit State Feedback for a Class of Queueing Systems

description: Motivated by medium access control for resource-challenged wireless Internet of Things (IoT), we consider the problem of queue scheduling with reduced queue state information. In particular, we consider a time-slotted scheduling model with $N$ sensor nodes, with pair-wise dependence, such that Nodes $i$ and $i + 1,~0 < i < N$ cannot transmit together. We develop new throughput-optimal scheduling policies requiring only the empty-nonempty state of each queue that we term Queue Nonemptiness-Based (QNB) policies. We propose a Policy Splicing technique to combine scheduling policies for small networks in order to construct throughput-optimal policies for larger networks, some of which also aim for low delay. For $N = 3,$ there exists a sum-queue length optimal QNB scheduling policy. We show, however, that for $N > 4,$ there is no QNB policy that is sum-queue length optimal over all arrival rate vectors in the capacity region. We then extend our results to a more general class of interference constraints that we call cluster-of-cliques (CoC) conflict graphs. We consider two types of CoC networks, namely, Linear Arrays of Cliques (LAoC) and Star-of-Cliques (SoC) networks. We develop QNB policies for these classes of networks, study their stability and delay properties, and propose and analyze techniques to reduce the amount of state information to be disseminated across the network for scheduling. In the SoC setting, we propose a throughput-optimal policy that only uses information that nodes in the network can glean by sensing activity (or lack thereof) on the channel. Our throughput-optimality results rely on two new arguments: a Lyapunov drift lemma specially adapted to policies that are queue length-agnostic, and a priority queueing analysis for showing strong stability.

description: The exact equation of spin motion in a cylindrical coordinate system with allowance for electric dipole moments of particles has been derived. This equation is convenient for analytical calculations of spin dynamics in circular storage rings when the configuration of main fields is simple enough. The generalized formula for the influence of a vertical betatron oscillation on the angular velocity of spin rotation has been found. This formula agrees with the previously obtained result and contains an additional oscillatory term that can be used for fitting. The relative importance of terms in the equation of spin motion is discussed.

Warm gas in the outskirts of galaxy clusters -- The cluster soft excess phenomenon

description: The cluster soft excess emission indicates the presence of large amounts of warm gas (T ~ 10^6 K) in the neighborhood of galaxy clusters. Among the clusters that display this phenomenon is the Coma cluster, the nearest rich galaxy cluster. The excess emission is more prominent at the cluster's outskirts than at its center. Detailed studies of its large-scale emission -- up to ~2.6 Mpc from the cluster's center -- reveal that these warm baryons are as massive as, or possibly more massive than, the well-known hot intra-cluster medium (T ~10^8 K). A possible interpretation of the excess emission from the Coma cluster is radiation from low-density filaments located in the neighborhood of the cluster. In this case, the filaments would extend for much larger distances, or feature higher density, than predicted by current cosmological simulations.

description: We examine the renormalized free energy of the free Dirac fermion and the free scalar on a (2+1)-dimensional geometry $\mathbb{R} \times Σ$, with $Σ$ having spherical topology and prescribed area. Using heat kernel methods, we perturbatively compute this energy when $Σ$ is a small deformation of the round sphere, finding that at any temperature the round sphere is a local maximum. At low temperature the free energy difference is due to the Casimir effect. We then numerically compute this free energy for a class of large axisymmetric deformations, providing evidence that the round sphere globally maximizes it, and we show that the free energy difference relative to the round sphere is unbounded below as the geometry on $Σ$ becomes singular. Both our perturbative and numerical results in fact stem from the stronger finding that the difference between the heat kernels of the round sphere and a deformed sphere always appears to have definite sign. We investigate the relevance of our results to physical systems like monolayer graphene consisting of a membrane supporting relativistic QFT degrees of freedom.

description: One of the indisputable consequences of globalization is the world-wide linking of market agents and creation of global networks. The possible impacts of these processes are apparent also in the agro-food sector, especially within the networks of commodity chains. Coffee, the second most heavily traded commodity in the world, is a typical example, featuring as a global commodity chain. It means that its individual production stages are miles distant. The first stage of analyzed value chain, coffee growing, is situated in developing countries of Latin America, Asia and Africa, while the processing and consumption are carried out mostly in developed countries such as the US or the EU. This paper is focused on the analysis of the individual production stages within the coffee commodity chain. Furthermore, the position of developing countries producing the raw commodity, interrelationships along the whole value chain and market concentration on the individual stages are subjects of the analysis as well. The results have been obtained within the frame of the research project MSM 6215648904 "The Czech Economy in the Process of Integration and Globalisation, and the Development of Agricultural Sector and the Sector of Services under the New Conditions of the Integrated European Market" of Mendel University in Brno, Faculty of Regional Development and International Studies.

The method is based on the calculation of rigorous lower bounds on the ground state energy density in the infinite-lattice limit. Such bounds are useful in the discussion of supersymmetry phase transition. The transition point is determined with this method and then compared with recent results based on large-scale Green Function Monte Carlo simulations with good agreement.

title: Antigen Presentation by MHC Class I and CD1 Molecules
Creators: name: Gadola, Stephan D.
Publisher: name: The Open University
Year: 2009

description: Antigen presentation is the “sine qua non” of the mammalian adaptive immune system. The assembly of MHC class I/peptide complexes in the endoplasmic reticulum (ER) relies on the orchestrated interplay between different chaperonins, which assist MHC class I folding, and the peptide loading complex (PLC). Mutant lymphoblastoid cell lines with defective MHC class I surface expression have greatly helped the functional analysis of the PLC. The TAP transporter associated with antigen processing translocates MHC class I peptide ligands from the cytosol into the ER and is critical for successful MHC class I assembly and maturation. In the first two results chapters of this thesis I will describe the identification, clinical description and molecular and genetic analysis of a new clinical syndrome in a group of patients with dramatically reduced MHC class I surface expression. The disease in these patients could be identified as primary TAP-deficiency. Mycobacterial infections were conspicuously absent in these TAP-deficient patients whereas TAP-deficient mice are known to be highly susceptible to mycobacteria. The focus of the third and fourth chapter of this thesis lies on lipid antigen presentation via CD1 molecules, which are known to present mycobacterial lipids to T lymphocytes. The first objective of this thesis was to generate recombinant mycobacterial lipid loaded CD1 molecules as tools to measure mycobacterial lipid specific T cell responses in the TAP-deficient patients. Chapters three and four describe novel protocols for the generation of recombinant human CD 1b and CD 1d molecules with loaded single lipid species.

It pays special attention to envelopment version of IDEA model (EIDEA), proposes modification of the Zhu (2003a) procedure for converting ordinal data to exact data and applies the procedure in efficiency analysis of 193 agro-food firms when impact of ICT use is taken as an efficiency factor. Analysis results by EIDEA are compared with standard CCR DEA results. The comparison shows that the standard model underestimates efficiency what seems to be a consequence of incorrect consideration of ordinal data.

description: Sample-based learning model predictive control (LMPC) strategies have recently attracted attention due to their desirable theoretical properties and their good empirical performance on robotic tasks. However, prior analysis of LMPC controllers for stochastic systems has mainly focused on linear systems in the iterative learning control setting. We present a novel LMPC algorithm, Adjustable Boundary Condition LMPC (ABC-LMPC), which enables rapid adaptation to novel start and goal configurations and theoretically show that the resulting controller guarantees iterative improvement in expectation for stochastic nonlinear systems. We present results with a practical instantiation of this algorithm and experimentally demonstrate that the resulting controller adapts to a variety of initial and terminal conditions on 3 stochastic continuous control tasks.

The circumstances which drove the derivation of two distinct communities - kuṁḷbī and Deccan caḍḍī – from the encounter of native Indian (possibly vēdar) and kṣatrīya ancestries, were probably related to the trajectory of the movement of the kṣatrīya in Deccan and their eventual settlement.

description: The rapidly developing field of ferromagnetism in diluted magnetic semiconductors, where a semiconductor host is magnetically doped by transition metal impurities to produce a ferromagnetic semiconductor (e.g. Ga_{1-x}Mn_xAs with x ~ 1-10 %), is discussed with the emphasis on elucidating the physical mechanisms underlying the magnetic properties. Recent key developments are summarized with critical discussions of the roles of disorder, localization, band structure, defects, and the choice of materials in producing good magnetic quality and high Curie temperature. The correlation between magnetic and transport properties is argued to be a crucial ingredient in developing a full understanding of the properties of ferromagnetic semiconductors.

description: Gravitational waves from extreme gravity events such as the coalescence of two black holes in a binary system fill our observable universe, bearing with them the underlying theory of gravity driving their process. One compelling alternative theory of gravity -- known as Einstein-dilaton Gauss-Bonnet gravity motivated by string theory -- describes the presence of an additional dilaton scalar field coupled directly to higher orders of the curvature, effectively describing a "fifth force" interaction and the emission of scalar dipole radiation between two scalarized black holes. Most previous studies focused on considering only the leading correction to the inspiral portion of the binary black hole waveforms. In our recent paper, we carried out inspiral-merger-ringdown consistency tests in this string-inspired gravity by including corrections to both the inspiral and ringdown portions, as well as those to the mass and spin of remnant black holes, valid to quadratic order in spin. We here extend the analysis by directly computing bounds on the theoretical coupling constant using the full inspiral-merger-ringdown waveform rather than treating the inspiral and merger-ringdown portions separately. We also consider the corrections valid to quartic order in spin to justify the validity of black hole's slow-rotation approximation. We find the quasinormal mode corrections to the waveform to be particularly important for high-mass events such as GW170729, in which the dilaton fields' small-coupling approximation fails without such effects included. We also show that future space-based and multiband gravitational-wave observations have the potential to go beyond existing bounds on the theory. The bounds presented here are comparable to those found in via the inspiral-merger-ringdown consistency tests.

description: We present a mechanical analog of a quantum wave-particle duality: a vibrating string threaded through a freely moving bead or `masslet'. For small string amplitudes, the particle movement is governed by a set of non-linear dynamical equations that couple the wave field to the masslet dynamics. Under specific conditions, the particle achieves a regime of {\it transparency} in which the field and the particle's dynamics appear decoupled. In that special case, the particle conserves its momentum and a guiding wave obeying a Klein-Gordon equation, with real or imaginary mass, emerges. Similar to the double-solution theory of de Broglie, this guiding wave is locked in phase with a modulating group-wave co-moving with the particle. Interestingly, both subsonic and supersonic particles can fall into a quantum regime as with the slower-than-light bradyons and hypothetical, faster-than-light tachyons of particle physics.

description: Excerpts from the report Summary: Increased effectiveness of supermarket managers resulted from improved management practices developed and tested in controlled experimentation. The new practices resulted in considerably better adherence to company directives, improved employee relations in the store, and better work methods. These, in turn, led to more effort going into store merchandising, and increased sales per man-hour. The research was conducted in 28 stores of an eastern supermarket organization. New manager practices were tested in 14 of the stores and the other 14 were used as matched controls. Data used in measuring results were gathered during the same period for both groups of stores. Improved practices were developed in three broad areas of work for which store managers are responsible: (1) Adherence by employees to company directives on store merchandising; (2) the management of store employees, and (3) the application of techniques for simplifying work in the stores.

description: In terms of economic development, Russia before and after the Soviet era was just an average economy. If the Soviet era is distinguished, it was not by economic growth or its contribution to human development, but by the use of the economy to build national power over many decades. In this respect, the Soviet economy was a success. It was also a tough and unequal environment in which to be born, live, and grow old. The Soviet focus on building national capabilities did improve opportunities for many citizens. Most important were the education of women and the increased survival of children. The Soviet economy was designed for the age of mass production and mass armies. That age has gone, but the idea of the Soviet economy lives on, fed by nostalgia and nationalism.
Subleading collinear operators and their matrix elements

description: We discuss the most general form of the leading power suppressed collinear operators in the soft-collinear effective theory. Such operators appear in the description of power corrections to exclusive heavy flavor decays into energetic light hadrons. Reparametrization invariance in the SCET provides powerful constraints on the Wilson coefficients of the subleading collinear operators. We present explicit results for the matrix elements of these operators on pseudoscalar and vector mesons, which are expressed in terms of twist-2 and twist-3 light-cone wave functions. We consistently include the effects of three-particle light-cone distribution amplitudes and find that their impact could be of phenomenological relevance.

title: Autoantibody Profiling of Cerebrospinal Fluid From Affective Disorders and Schizophrenia Patients by Phage Display: Method Optimization and Evaluation of Selected Autoantigens As Candidate Biomarkers
Creators: name: Sayan-Ayata, F. Eser
Publisher: name: The Open University
Year: 2009

description: Immunoproteomics approach applied on affective disorder and schizophrenia patient CSF samples yielded a number of candidate autoantigens. An overall analysis of those candidates revealed that impairment of myelination might have a role in etiology of such psychiatric disorders. Validations were based on phage ELISA that is applied on the most prominent autoantigen candidate obtained from phage display selection. In parallel, a conventional ELISA by recombinant peptide rather then purified phage, helped reproduce the results that imply a tendency of autoimmune reactivity in patient CSF samples compared to controls. Comparison of these results with the closest family members of the candidate protein mapping to the same N-terminal sequence revealed that, the sequence obtained by phage display is more antigenic than its homologues. Genomic expression profile of selected candidate and three other functionally related schizophrenia susceptibility genes were studied on mRNA in brain and spinal cord of mice, from postnatal day one until postnatal day forty-two. We could observe patterns of expression that may suggest a possible interplay of candidate proteins in the relevant neuronal maintenance mechanism. Our approach using cDNA phage display used in the identification of autoantigens in inflammatory and autoimmune diseases of the CNS is quite feasible despite several drawbacks like high false-positive number. Finally, our results may raise interest on myelination related proteins that may have roles in schizoaffective symptoms. However, strictly more effort has to be implemented to confirm and get more insight on our findings, for example developing mouse models and studying a broader range of serum and CSF samples.
Kilonova Emission From Black Hole-Neutron Star Mergers. I. Viewing-Angle-Dependent Lightcurves

description: In this paper, we present a numerical method to study the predicted lightcurves as a function of viewing angle. We extrapolate the fitting formulae for the mass and velocity of tidal dynamical ejecta across a wide range of mass ratio validated with 66 simulations and use them in the calculations of the kilonova lightcurves. The calculated peak luminosity of a BH-NS merger kilonova is typically about a few times $10^{41}\ {\rm erg\ s^{-1}}$, which is always $\lesssim4.5\times10^{41}\ {\rm erg\ s^{-1}}$. This corresponds to the AB absolute magnitudes fainter than $\sim -15\ {\rm mag}$ in optical and $\sim -16\ {\rm mag}$ in infrared. Since the projected photosphere area of the dynamical ejecta is much larger than that of the disk wind outflows, the dynamical ejecta usually contribute to the majority of the kilonova emission from BH-NS mergers. The fitted blackbody temperature and the shape of the observed multi-band lightcurves are insensitive to the line of sight. The peak time of the observed multi-band lightcurves, affected by the light propagation effect, is related to the relative motion direction between the dynamical ejecta and the observer. The observed luminosity varies with the projected photosphere area determined by the viewing angles. However, the predicted peak luminosity only varies by a factor of $\sim (2 - 3)$ (or by $\sim1\ {\rm mag}$) for different viewing angles. When the short-duration gamma-ray burst afterglow is taken into account, for an on-axis geometry, the kilonova emission is usually outshone by the afterglow emission and can be only observed in the redder bands, especially in the $K$-band at late times. Compared with GW170817/AT2017gfo, the BH-NS merger kilonovae are optically dim but possibly infrared bright. At the same epoch after the merger, the blackbody fitting temperature of the BH-NS merger kilonovae is lower than that of GW170817/AT2017gfo.
