Correlated changes in behaviour and glutamate receptor expression as a result of early stimulation in Caenorhabditis elegans
Creators: name: Ebrahimi, Celia Mariah
Publisher: name: University of British Columbia
Year: 2010

description: The effects of early sensory experience on the development of central nervous system structures and behavior are the focus of much ongoing research. Previous studies have demonstrated that exposing animals to sensory enriched environments produced significant changes in the nervous system and accelerated and improved the development of complex cognitive behaviors such as learning and memory; however the long-term effects of sensory enriched environments on the nervous system and behavior remain unknown. In this study, I investigated the long-term effects that an enhancement in mechanosensory experience produced on adult behavior and glutamate receptor-1 (GLR-1) distribution in the nematode Caenorhabditis elegans (C elegans). I found that C. elegans exposed to an enhancement in mechanosensory stimulation exhibited different behavioral and molecular outcomes depending on the temporal pattern of mechanosensory stimulation, the age of the worm stimulated and the age of the worm tested. Early spaced mechanosensory stimulation at a long inter-stimulus interval produced two independent behavioral effects, an early enhancement at 3 days followed by a depression at 5 days. Both behaviors were dependent on glutamate activity and were associated with a positively correlating change in both glutamate receptor-1 protein distribution and mRNA levels. The 3 day behavioral enhancement was not observed when spaced mechanosensory stimulation was delivered later in larval development, suggesting a critical period for these effects early in larval development. There appeared to be no critical period for the depressed behavioral response observed at 5 days; however only the depressed behavioral response of 5 day old worms was found to be sensitive to reconsolidation blockade. These results suggest that early mechanosensory stimulation produces two independent effects in adult worms: an early developmental effect in 3 day old worms which is mediated by one cellular event and a long-term memory effect at 5 days which is mediated by a separate cellular phenomenon. The results from this study have provided novel information into the long-term effects that an enhancement in early sensory experience had on the behavior and molecular properties of the adult nervous system, and provided the foundation for future research in this field.

description: Neutron scattering experiments were performed on the undoped and hole-doped Ca$_{2+x}$Y$_{2-x}$Cu$_5$O$_{10}$, which consists of ferromagnetic edge-sharing CuO$_2$ chains. It was previously reported that in the undoped Ca$_2$Y$_2$Cu$_5$O$_{10}$ there is an anomalous broadening of spin-wave excitations along the chain, which is caused mainly by the antiferromagnetic interchain interactions [Matsuda $et$ $al.$, Phys. Rev. B 63, 180403(R) (2001)]. A systematic study of temperature and hole concentration dependencies of the magnetic excitations shows that the magnetic excitations are softened and broadened with increasing temperature or doping holes irrespective of $Q$ direction. The broadening is larger at higher $Q$. A characteristic feature is that hole-doping is much more effective to broaden the excitations along the chain. It is also suggested that the intrachain interaction does not change so much with increasing temperature or doping although the anisotropic interaction and the interchain interaction are reduced. In the spin-glass phase ($x$=1.5) and nearly disordered phase ($x$=1.67) the magnetic excitations are much broadened in energy and $Q$. It is suggested that the spin-glass phase originates from the antiferromagnetic clusters, which are caused by the hole disproportionation.

description: The Listen, Attend and Spell (LAS) model and other attention-based automatic speech recognition (ASR) models have known limitations when operated in a fully online mode. In this paper, we analyze the online operation of LAS models to demonstrate that these limitations stem from the handling of silence regions and the reliability of online attention mechanism at the edge of input buffers. We propose a novel and simple technique that can achieve fully online recognition while meeting accuracy and latency targets. For the Mandarin dictation task, our proposed approach can achieve a character error rate in online operation that is within 4% relative to an offline LAS model. The proposed online LAS model operates at 12% lower latency relative to a conventional neural network hidden Markov model hybrid of comparable accuracy. We have validated the proposed method through a production scale deployment, which, to the best of our knowledge, is the first such deployment of a fully online LAS model.

description: We present an experimental realisation of Hardy's thought experiment [Phys. Rev. Lett. {\bf 68}, 2981 (1992)], using photons. The experiment consists of a pair of Mach-Zehnder interferometers that interact through photon bunching at a beam splitter. A striking contradiction is created between the predictions of quantum mechanics and local hidden variable based theories. The contradiction relies on non-maximally entangled position states of two particles.

description: A quantum extremal island suggests that a region of spacetime is encoded in the quantum state of another system, like the encoding of the black hole interior in Hawking radiation. We study conditions for islands to appear in general spacetimes, with or without black holes. They must violate Bekenstein's area bound in a precise sense, and the boundary of an island must satisfy several other information-theoretic inequalities. These conditions combine to impose very strong restrictions, which we apply to cosmological models. We find several examples of islands in crunching universes. In particular, in the four-dimensional FRW cosmology with radiation and a negative cosmological constant, there is an island near the turning point when the geometry begins to recollapse. In a two-dimensional model of JT gravity in de Sitter spacetime, there are islands inside crunches that are encoded at future infinity or inside bubbles of Minkowski spacetime. Finally, we discuss simple tensor network toy models for islands in cosmology and black holes.

description: We have investigated negative-parity uudd\bar{s} pentaquarks by employing a quark model with the meson exchange and the effective gluon exchange as qq and q\bar{q} interactions. The system for the five quarks is dynamically solved; the effects of qq and q\bar{q} correlations on the wave function are taken into account. It is found that the masses of the pentaquarks are reasonably low. The lowest-mass state is found to be TJ^P=0{1/2}^-, and the next lowest one is 0{3/2}^-. The former is reported to have a large width. We argue the observed narrow peak corresponds to the latter state. It is still necessary to introduce an extra attraction to reduce the mass further by 140 -- 280 MeV to reproduce the observed Θ^+ mass. Since their level splitting is found to be less than 80 MeV, the lower level will not become a bound state below the NK threshold even after such an attraction is introduced. It is also found that the relative distance of two quarks with the attractive interaction is found to be by about 1.2 -- 1.3 times closer than that of the repulsive one. The two-body correlation seems important in the pentaquark systems.

The Temperature Structure of the Warm-Hot Intergalactic Medium

description: We study the temperature structure of the intergalactic medium (IGM) using a large cosmological N-body/SPH simulation. We employ a two-temperature model for the thermal evolution of the ionized gas, in which the relaxation process between electrons and ions is explicitly included. In the diffuse, hot IGM, the relaxation time is comparable to the age of the Universe and hence the electron temperature in post-shock regions remains significantly smaller than the ion temperature. We show that, at the present epoch, a large fraction of the warm/hot intergalactic medium (WHIM) has a well-developed two temperature structure, with typical temperature differences of order a factor of a few. Consequently, the fraction of metals in various ionization states such as OVI, OVII, and OVIII, as well as their line emissivities, can differ locally by more than an order of magnitude from those computed with a single temperature model. It is thus necessary to follow the evolution of the electron temperature explicitly to determine absorption and emission by the WHIM. Although equipartition is nearly achieved in the denser intracluster medium (ICM), we find an appreciable systematic deviation between the gas-mass weighted electron temperature and the mean temperature even at half the virial radii of clusters. There is thus a reservoir of warm (Te < 1keV) gas in and around massive clusters. Our results imply that relaxation processes need to be considered in describing and interpreting observational data from existing X-ray telescopes as well as from future missions designed to detect the WHIM, such as the Diffuse Intergalactic Oxygen Surveyor and the Missing Baryon Explorer.

description: The local density of states (LDOS) and its Fourier component induced by a unitary impurity in a supercurrent-carrying d-wave superconductor are investigated. Both of these quantities possess a reflection symmetry about the line passing through the impurity site and along the supercurrent if it is applied along the antinodal or nodal direction. With increasing supercurrent, both the coherence and resonant peaks in the LDOS are suppressed and slightly broadened. Under a supercurrent along the antinodal direction, the coherence peaks split into double peaks. The modulation wavevectors associated with elastic scatterings of quasiparticles by the defect from one constant-energy piece of the Fermi surface to another are displayed as bright or dark spots in the Fourier space of the LDOS image, and they may be suppressed or enhanced, and shifted depending on the applied current and the bias voltage.

description: Gross--Oliveira--Kohn (GOK) ensemble density-functional theory (GOK-DFT) is a time-\textit{independent} extension of density-functional theory (DFT) which allows to compute excited-state energies via the derivatives of the ensemble energy with respect to the ensemble weights. Contrary to the time-dependent version of DFT (TD-DFT), double excitations can be easily computed within GOK-DFT. However, to take full advantage of this formalism, one must have access to a \textit{weight-dependent} exchange-correlation functional in order to model the infamous ensemble derivative contribution to the excitation energies. In the present article, we discuss the construction of first-rung (i.e., local) weight-dependent exchange-correlation density-functional approximations for two-electron atomic and molecular systems (He and H$_2$) specifically designed for the computation of double excitations within GOK-DFT. In the spirit of optimally-tuned range-separated hybrid functionals, a two-step system-dependent procedure is proposed to obtain accurate energies associated with double excitations.

description: A brain tumor is one of the hazardous diseases. Hence, it is necessary to detect the brain tumor appropriately. The detection of brain tumor by processing of magnetic resonance image (MRI) is one of the medical imaging techniques. It is most difficult task for clinical experts to extract the brain tumor by manual inspection because there is variation in tumor size, shape and location. Hence, image processing technique is used for detection of brain tumor. In this paper, by using K means clustering method brain MRI image is segregated in clusters. Then the cluster with tumor is found. But noise can degrade the quality of the image and it can affect the performance of segmentation process. Hence, anisotropic diffusion filter is used for noise reduction, before segmentation process. Morphological operations are applied to segmented image for image enhancement. Finally, the tumor is detected. Some useful features are extracted using gray- level co-occurrence matrix.

description: Aim of this study is an analysis of the land expanse, which provide basic data for the rational design of land expanse in the land integration of villages and enable a forecast benefits of the land integration. The land integration is usually preceded by more or less detailed analysis of the land expanse. It is the purpose of this paper to determine a degree of land disaggregation in the village and finding possibilities for improving it. The article also focuses on establishing the rules and parameters for reconstruction of the existing land configuration and estimation the land integration effects. The valuation of geometrical parameters of a land expanse is made on the basis of a chosen group of farms. Considering their parameters of a land expanse chooses the farms for a detailed analysis. These parameters should be similar to average ones that characterise the whole village. The chosen group should number from 5 to 10% of a total number of farms. The described method of the land expanse analysis for needs to their integration was presented in the Lapsze Wyzne village situated in Nowotarski district, Malopolska province as an example. Execution of land integration in the village with a large land disaggregation contributes to a considerable improvement of a land expanse (increase of an area of agricultural plots and decrease of a distance between agricultural plots and homesteads).

description: One of the most important tools for increasing business performance is to provide a proper level of financial resources, which is important for the continuity of all business establishments. Those factors that determine agricultural financing have specific characteristics. Due to the specifics of rural economies, agricultural enterprises have a low capacity for self-financing, thus they need significant external resources. After EU accession there has been a significant increase of subsidies received by farmers, but the distribution of support is not equal and available for all. Our aim was to analyse agricultural HUF and FX short term loans between the years 1995 and 2013 to find out the relationship between foreign currency and the effects of strengthening of Hungarian forint. We tried to find trends, we created forecasts and analyzed them with two different methods to get aproperview on correlation and chenges in this period. Agriculture, like all sectors of the economy, needs credit loans for its development. In a competitive financial environment, profitable agriculture can obtain the credit loan it needs. Bank lending becomes this economy’s engine.

description: Tricritical Ising (TCI) phase transition is known to occur in several interacting spin and Majorana fermion models and is described in terms of a supersymmetric conformal field theory (CFT) with central charge $c=7/10$. The field content of this CFT is highly nontrivial and includes among its primary fields the Fibonacci anyon, making it of potential interest to strategies seeking to implement fault-tolerant topological quantum computation with non-Abelian phases of matter. In this paper we explore the possibility that a TCI CFT can occur at the edge of a gapped two-dimensional topological state as a stable phase. We discuss a possible realization of this 2D phase based on a coupled-wire construction using the Grover-Sheng-Vishwanath chain model of Majorana zero modes coupled to Ising spins which is known to undergo the TCI phase transition. From the combined analysis using mean-field theory, conformal field theory and density matrix renormalization group (DMRG) on 2- and 4-leg ladders, we find that the left- and right-moving gapless TCI modes become spatially separated and reside on two opposite edges of the system, forming a precursor of the required 2D topological phase.

description: Regarding long life particles produced during preheating after inflation as dark matter, we find that its back reaction on the field $ϕ$ could lock $ϕ$ in a false vacuum up to today. This false vacuum can drive the accelerated expansion of universe at late time and play the role of dark energy. When the number density of dark matter particles is dilute to some value, the field $ϕ$ becomes tachyonic and rolls to its true minima rapidly, and the acceleration of universe ceases. We discuss the constraints on the parameters of model from the observations of dark energy and dark matter halos on subgalactic scale.

description: The objective of the study was to evaluate the profitability of starchy potato cultivation on an agricultural holding in the years 2010-2012. Empirical data was obtained from the owner of the farm who has signed a longterm contract and cooperated with the food industry enterprise ‘PEPEES’ in Łomża. The highest marketable yield of starchy tubers was recorded in 2011. The production value per 1 ha varied in individual years and ranged from 6,002.0 to 10,649.6 PLN. The income was highly variable in individual years depending on the yield level and the price per produced unit. Direct costs affected the economic effectiveness of starchy potato cultivation, too. Seed potato and fuel costs accounted for the greatest proportion of the total costs. Starchy potato production was the most profitable in 2011.
Field emission mechanisms of graphitic nanostructures

description: Field emission (FE) and the electronic-states origin of graphitic nanostructures were investigated by first-principles calculations based on time-dependent density-functional theory. We find that the FE current from graphitic ribbons changes remarkably depending on the hydrogen termination and the direction of the applied electric field. Also, the FE current from graphene sheets shows a dramatic increase around vacancy defects. We verified, through the analysis of local electronic structures and energy distributions of emitted electrons, that the dangling-bond (or $σ$) character is responsible for these results and governs the nature of the FE of graphitic nanostructures.

description: The purpose of the article was to present the opinions of farmers on insurance companies in the three voivodeships of mazowieckie, łódzkie and wielkopolskie. There were also presented selected factors that farmers take into account when choosing an insurance company. It was found that the surveyed farmers purchased insurance products primarily in PZU S.A. The majority of farmers represented by 60% of the researched population purchased insurance products offered by PZU, regardless of insurance type. It has been shown that the main factors determining the choice of a particular insurance company were among others: price, wellknown brand, confidence in the insurance company, the experience gained in dealing with its representatives
Orbital tunable 0-$π$ transitions in Josephson junctions with noncentrosymmetric topological superconductors

description: We investigate the Josephson transport properties in a Josephson junction consisting of a conventional $s$-wave superconductor coupled to a multi-orbital noncentrosymmetric superconductor marked by an orbitally driven inversion asymmetry and isotropic interorbital spin-triplet pairing. Contrary to the canonical single band noncentrosymmetric superconductor, we demonstrate that the local interorbital spin-triplet pairing is tied to the occurrence of sign-changing spin-singlet pair amplitude on different bands with $d$-wave symmetry. Such multi-band $d^{\pm}$-wave state is a unique superconducting configuration that drives unexpected Josephson effects with 0-$π$ transitions displaying a high degree of electronic control. Remarkably, we find that the phase state of a noncentrosymmetric/$s$-wave Josephson junction can be toggled between 0 and $π$ in multiple ways through a variation of electron filling, strength of the spin-orbital coupling, amplitude of the inversion asymmetry interaction, and junction transparency. These results highlight an intrinsic orbital and electrical tunability of the Josephson response and provide unique paths to unveil the nature of unconventional multiorbital superconductivity as well as inspire innovative designs of Josephson quantum devices.

Market adaptability, industrial divergence, and the politics of liberalization in the Kenyan and Ugandan coffee industries
Creators: name: Damianopoulos, Richard Anthony
Publisher: name: University of British Columbia
Year: 2010

description: This study explains market adaptability, industrial divergence, and liberalization in the Kenyan and Ugandan coffee industries by addressing two fundamental questions: is liberalization responsible for divergence in the coffee sectors of Kenya and Uganda and; moreover, why has Uganda liberalized while Kenya has not? It will be demonstrated that liberalization is a major factor responsible for industry divergence and that, from the colonial period to the present, socio-political variables have been the primary force driving the decision of the domestic bourgeoisie to liberalize in Uganda and the failure to do so in Kenya. It is argued that socio-political variables act, by influencing the domestic bourgeoisie, as change agents that determine Kenya and Uganda's path choice of liberalization and continuation of an illiberal status quo respectively. This study assumes that states have full knowledge of international market signals. Looking at the case of the domestic coffee industries in Kenya and Uganda, Kenya has opted for continuation of the illiberal status quo whereas Uganda has opted for liberalization. This particular path choice occurred because it was perceived as beneficial by the Ugandan domestic bourgeoisie to adapt to the global coffee economy by liberalizing domestic industry whereas the Kenyan domestic bourgeoisie perceived the maintenance of the status quo as beneficial, even at the expense of generating sub-optimal economic outcomes for the domestic coffee industry. The impetus behind both path choices is socio-political, involving the pursuit of defined elite interests in the context of a historical dialectic between competing foci of power.

description: The willingness to pay (WTP) is a vital component in assessing the healthcare delivery preference of people in a socioeconomic framework. Unemployment and underemployment have dictated the ability to pay (ATP) and the income of the Filipino families. Income is a compelling indicator of WTP for healthcare. From purposively sampled participants of Cebuano mothers (n=140), this exploratory cross-sectional survey aimed to know their WTP levels for general dental healthcare and specific services through a web-based questionnaire.

description: We present a novel technique called Dynamic Experience Replay (DER) that allows Reinforcement Learning (RL) algorithms to use experience replay samples not only from human demonstrations but also successful transitions generated by RL agents during training and therefore improve training efficiency. It can be combined with an arbitrary off-policy RL algorithm, such as DDPG or DQN, and their distributed versions. We build upon Ape-X DDPG and demonstrate our approach on robotic tight-fitting joint assembly tasks, based on force/torque and Cartesian pose observations. In particular, we run experiments on two different tasks: peg-in-hole and lap-joint. In each case, we compare different replay buffer structures and how DER affects them. Our ablation studies show that Dynamic Experience Replay is a crucial ingredient that either largely shortens the training time in these challenging environments or solves the tasks that the vanilla Ape-X DDPG cannot solve. We also show that our policies learned purely in simulation can be deployed successfully on the real robot.
