description: We show in simulations that overdamped interacting particles in two dimensions with a randomly disordered substrate can exhibit novel nonequilibrium transport phenomena including a transverse ratchet effect, where a combined dc drive and circular ac drive produce a drift velocity in the direction transverse to the applied dc drive. The random disorder does not break any global symmetry; however, in two dimensions, symmetry breaking occurs due to the chirality of the circular drive. In addition to inducing the transverse ratchet effect, increasing the ac amplitude also strongly affects the longitudinal velocity response and can produce what we term an overshoot effect where the longitudinal dc velocity is higher in the presence of the ac drive than it would be for a dc drive alone. We also find a dynamical reordering transition upon increasing the ac amplitude. In the absence of a dc drive, it is possible to obtain a ratchet effect when the combined ac drives produce particle orbits that break a reflection symmetry. In this case, as the ac amplitude increases, current reversals can occur. These effects may be observable for vortices in type II superconductors as well as for colloids interacting with random substrates.

description: With a sample of farms in the European Union (EU) and Farm Accountancy Data Network (FADN) data completed by additionally collected data, we illustrate how the effect of farm subsidies on technical efficiency changes when environmental outputs are incorporated in the calculation of technical efficiency. Results indicate that the effect of the Common Agricultural Policy (CAP) operational subsidies on farm technical efficiency changes when environmental outputs (namely greenhouse gas emissions, nitrogen balance and ecological focus areas) are taken into account in the efficiency calculation: some effects change significance, and more importantly, some effects change sign.

description: Prenylated chalcones are a family of natural chalcones that have been reported to exhibit a high antioxidant activity. In this paper, the density functional calculations are carried out to study, systematically, the antiradical properties of four prenylated natural chalcones namely isobavachalcone (I), xanthohumol (II), desmethylxanthohumol (III) and broussochalcone (IV). The radical scavenging ability of all the possible CH and OH bonds of chalcones I-IV were discussed in detail thermodynamically and kinetically. The results reveal that the CH bonds of the prenyl substituent are the most thermodynamically preferred sites for free radical attack, and thus play an important role on the antiradical activity of the investigated chalcones. For the OH bonds, it has been found that the B ring is more preferred for attacking free radicals than the A ring. Kinetic investigations have revealed that the CH bond and the OH bonds of the B ring can trap HO•/HOO• radicals. These results are of great significance in better understanding the chemical mechanism of the radical-scavenging action and open new perspectives for the design of new potent antioxidant agents.

description: Autonomous car racing is a major challenge in robotics. It raises fundamental problems for classical approaches such as planning minimum-time trajectories under uncertain dynamics and controlling the car at the limits of its handling. Besides, the requirement of minimizing the lap time, which is a sparse objective, and the difficulty of collecting training data from human experts have also hindered researchers from directly applying learning-based approaches to solve the problem. In the present work, we propose a learning-based system for autonomous car racing by leveraging a high-fidelity physical car simulation, a course-progress proxy reward, and deep reinforcement learning. We deploy our system in Gran Turismo Sport, a world-leading car simulator known for its realistic physics simulation of different race cars and tracks, which is even used to recruit human race car drivers. Our trained policy achieves autonomous racing performance that goes beyond what had been achieved so far by the built-in AI, and, at the same time, outperforms the fastest driver in a dataset of over 50,000 human players.

description: Designing the effective metallodrugs with amphiphilic nature is an active approach for the biomedical applications such as chemotheraphy, bioimaging, drug carrier, etc. To elaborate this, some fluorescent emissive surfactant–ruthenium(II) complexes and its precursor ruthenium(II) complexes have been interacted with calf thymus DNA (CT–DNA) for understanding the biophysical impacts of head and tail parts of the metallosurfactants. Here, DNA binding studies were examined by UV–visible absorption, fluorescence, circular dichroism and viscosity measurements. The obtained results showed that surfactant–ruthenium(II) complexes effectively bind with CT–DNA through hydrophobic interactions dominated moderate intercalation, whereas precursor ruthenium(II) complexes interact CT–DNA through electrostatic interactions dominated moderate intercalation. Also, increase of hydrophobic alkyl amine chain length as well as size of the head group in surfactant–ruthenium(II) complexes increased the binding affinity with CT–DNA, in which tail group played a dominant role. Further investigations of antibacterial, hemolytic and anticancer activities showed that desired biological activities could be obtained by tuning the head and tail groups of the metallodrugs in near future.

description: Recent models assessing the market impacts of Common Agricultural Policy (CAP) reforms are mostly static, non-stochastic and do not account for risks. This paper is a first attempt to fill this gap. We develop a stochastic version of GTAP-AGR model in which we introduce productivity risk and farmers' attitude towards risks. In addition to the price expectation, the expectation on price volatility becomes a key factor for the farmers' decisions. We show that under the endogenous modeling of the CAP instruments, risk aversion leads to larger production and price effects. The impacts are even larger if wealth effect is considered.
Troubling modernity : spatial politics, technologies of seeing and the crisis of the city and the World's Exhibition in fin de siecle Budapest
Creators: name: Barenscott, Dorothy
Publisher: name: University of British Columbia
Year: 2011

description: Conflicts and concerns around representing ethnic, class, and national identities within the context of modern national ideologies have come to the fore in recent years. Yet these same problems were current and actively being negotiated in the nineteenth century in Central and Eastern Europe's Austro-Hungarian Empire. This dissertation takes as its focus the role of visuality, new technologies, and social space in the articulation of competing identities in fin de siècle Budapest, Hungary. In 1896 the city hosted a Millennial Exhibition designed to simultaneously celebrate the history of the Hungarian people and the entry of Hungary into the larger European world economy. But, preparations within the city of Budapest itself--urban modernization, a state of the art transportation system, new architectural projects, and the design of mass entertainments--argued in different ways for Hungary's legitimacy as a progressive and modern state within the broader jurisdiction represented by the ruling Austrian Hapsburgs, and the imperial capital of Vienna. My thesis explores how different forms of mobility and circulation within both the shifting urban fabric of the city of Budapest, and the officially sanctioned spaces of its World's Fair, played a key role in re-defining Hungary's status under imperial rule. The four chapters of the dissertation which focus at their broadest level on the re-ordering of the spaces of the city, panorama spectacles, photography, and early cinema, thus consider the ways in which new modes of subjectivity, embodied vision and media forms, in dialogue with nationhood, gave form to a complex set of social and political tensions and debates at the time of the international exhibition.

description: Das Thema Frieden zwischen Israel und Palästinensern ist und bleibt dauerhaft aktuell. Bei einer Studientagung im Stuttgarter Lehrhaus für interreligiösen Dialog mit dem Titel Visionen von Israel widmeten wir uns am 10. April 2017 einen ganzen Sonntag lang dieser Thematik. Es war keine Harmonieveranstaltung. Vielstimmigkeit und Kontroverse waren angesagt und mit der Themenabfolge bewusst in das Programm eingebaut. Etwas davon wird in meinem folgenden Beitrag zu dieser Tagung mit dem Titel Frieden ist möglich – zur Perspektive einer Zwei- Staaten-Lösung zwischen Israel und Palästinensern deutlich werden. Wie der Titel schon andeutet, werde ich eine mögliche Vision und Version einer Friedenslösung darstellen. Andere Lösungen sind denkbar, wenn auch politisch zur Zeit nicht sichtbar. Persönlich und mit unserer Stiftung trete ich seit vielen Jahren durch die Unterstützung zivilgesellschaftlicher Friedensinitiativen in Israel und Palästina aktiv für Wege zum Frieden ein. Was machte die Aktualität des Themas gerade im Jahr 2017 aus? Politisch war es das Jahr der drei bedeutendsten Jubiläen in der jüngeren Geschichte des Staates Israel. Die Balfour-Deklaration ist 1917 ein Jahr vor dem Ende des Ersten Weltkriegs von Lord Balfour, der stellvertretender Außenminister der britischen Regierung war, veröffentlicht worden. In dieser ist zum ersten Mal in einer internationalen Erklärung eine nichtjüdische internationale Stellungnahme erschienen, in der dem jüdischen Volk die Zusicherung gemacht wird, im Land Palästina eine nationale Heimstätte einrichten zu dürfen.

description: In flux compactifications of M-theory a superpotential is generated whose explicit form depends on the structure group of the 7-dimensional internal manifold. In this note, we discuss superpotentials for the structure groups: G_2, SU(3) or SU(2). For the G_2 case all internal fluxes have to vanish. For SU(3) structures, the non-zero flux components entering the superpotential describe an effective 1-dimensional model and a Chern-Simons model if there are SU(2) structures.

description: We consider d-dimensional random surface models which for d=1 are the standard (tied-down) random walks (considered as a random ``string''). In higher dimensions, the one-dimensional (discrete) time parameter of the random walk is replaced by the d-dimensional lattice \Z^d, or a finite subset of it. The random surface is represented by real-valued random variables ϕ_i, where i is in \Z^d. A class of natural generalizations of the standard random walk are gradient models whose laws are (formally) expressed as P(dϕ) = 1/Z \exp[-\sum_{|i-j|=1}V(ϕ_i-ϕ_j)] \prod_i dϕ_i, V:\R -> R^+ convex, and with some growth conditions. Such surfaces have been introduced in theoretical physics as (simplified) models for random interfaces separating different phases. Of particular interest are localization-delocalization phenomena, for instance for a surface interacting with a wall by attracting or repulsive interactions, or both together. Another example are so-called heteropolymers which have a noise-induced interaction. Recently, there had been developments of new probabilistic tools for such problems. Among them are: o Random walk representations of Helffer-Sjöstrand type, o Multiscale analysis, o Connections with random trapping problems and large deviations We give a survey of some of these developments.

description: »From the heart of Jerusalem and the center of the world we proclaim again: Christ is Risen.« Mit diesen Worten sandten, wie jedes Jahr so auch zu Ostern 2019, die Patriarchen und Oberhäupter der lokalen Kirchen in Jerusalem ihre »Easter Message« in die Welt. Jerusalem, das Zentrum der Welt! Mit großem Selbstbewusstsein und tiefem Glauben schauen die Christen aus 13 verschiedenen Kirchen und Konfessionen darin auf ihre Stadt. Und wer einmal die Möglichkeit bekommt, im Katholikon, dem Gottesdienstraum der Griechisch-Orthodoxen Kirche innerhalb der Grabeskirche von Jerusalem, vorbeizuschauen, kann ihn mit eigenen Augen sehen: den Nabel der Welt, ein Stein, dessen Rundungen an einen Bauchnabel erinnern. Dabei teilen die Christen mit Juden und Muslimen diese jahrtausendealte Vorstellung. Für die beiden Letzteren ist der Tempelberg bzw. der Haram al-Sharif der Ort, der sich damit verbindet; für die Christen ist es die Stätte, an der sie Tod und Auferstehung ihres Herrn und Heilands Jesus Christus lokalisieren.

description: The purpose of the study was to examine the effectiveness of the communication of the region of origin in print advertising messages for wine bearing a GI label. An experimental design was used to manipulate the region of origin presentation in print advertisement (absent vs pictorial vs pictorial-textual) while measuring participant’s attitude towards the advertisement and purchase intention. Results provide empirical support to the appropriateness of highlighting the geographical area by combining textual – pictorial cues to induce a positive attitude towards the advertisement and purchase intention in consumers. The paper has useful implications for both marketing academics and professionals.

description: We present an analysis of the X-ray spectral properties of 61 hard X-ray selected (2-8 keV) sources from the bright ($f_{2-8 keV}>10^{-14}$ \funits) {\it XMM-Newton}/2dF survey. This comprises of 9 {\it XMM-Newton} pointings in the North Galactic Pole region ($\sim 1.6 \rm deg^2$) and overlaps with the SDSS, 2QZ and 2dFGRS surveys. Our sources contribute about 50 per cent of the 2-10 keV X-ray background down to the flux limit of $10^{-14}$ cgs. The hardness ratio distribution of the sample suggests a deficit of heavily absorbed sources. A spectral fit to the co-added total source spectrum yields a steep photon index, $Γ=1.83^{+0.04}_{-0.05}$. All but 8 sources have optical counterparts down to the SDSS photometric limit of $r\approx22.5$. Spectroscopic identifications exist for 34 sources. The vast majority are associated with Broad-Line (BL) AGN (24 sources) while only 7 present narrow or no emission lines. Five sources are probably associated with Galactic stars. Finally, for another 17 probable AGN we present photometric redshifts. The combined spectrum of the 24 spectroscopically identified BL AGN is steep ($Γ=2.02^{+0.04}_{-0.05}$), while that of the 7 AGN, which do not present broad lines is flatter with $Γ=1.64^{+0.11}_{-0.11}$. The spectrum of the 8 optically unidentified sources is flat with $Γ\approx 1.1$. Spectral fits to the individual BL AGN reveal large absorption (rest-frame column density $\rm>10^{22} cm^{-2}$) in only two cases. The individual spectra of the NL AGN present significant evidence for even a moderate absorption ($\rm 3\times 10^{21} cm^{-2}$) in only one case.

description: DNA topology changes continuously as replication proceeds. Unwinding of the DNA duplex by helicases is favored by negative supercoiling but it causes the progressive accumulation of positive supercoiling ahead of the fork. This torsional stress must be removed for the fork to keep advancing. Elimination of this positive torsional stress may be accomplished by topoisomerases acting solely ahead of the fork or simultaneously in the un-replicated and replicated regions after diffusion of some positive torsional strain from the un-replicated to the replicated regions by swivelling of the replication forks. In any case, once replication is completed fully replicated molecules are known to be heavily catenated and this catenation derives from pre-catenanes formed during replication. Although there is still controversy as to whether fork swiveling redistributes this positive torsional stress continuously or only as termination approaches, the forces that cause fork rotation and the generation of pre-catenanes are still poorly characterized. Here we used a numerical simulation, based on the worm-like chain model and the Metropolis Monte Carlo method, to study the interchange of supercoiling and pre-catenation in a naked circular DNA molecule of 4,440 bp partially replicated in vivo and in vitro. We propose that a dynamic gradient of torsional stress between the un-replicated and replicated regions drives fork swiveling allowing the interchange of supercoiling and pre-catenation.

description: Cyclic peptide nanotubes (CPNTs) are open-ended, hollow, and tubular structures that are made of several cyclic peptide rings. These structures can act as a transmembrane channel and transport ions or small molecules. In this work, we studied the stability of a cyclic peptide nanotube 8 × [(Trp-D-Leu)4-Gln-D-Leu] into a fully hydrated membrane composed of DPPC/POPC/POPS/cholesterol and also the transport mechanism of β-D-glucose through this nanotube was investigated. Our findings revealed that the CPNT was stable in the lipid bilayer during the simulation time and non-bonded interactions, especially hydrogen bonding have an important role to form a stable CPNT in the membrane. The glucose jumps from a Cα-region into the mid-Cα region and spends more time in this region because of its more desirable interactions with water molecules and the CPNT. In the transport pathway, non-bonded interactions between glucose, water molecules and the CPNT facilitate the transport of the glucose through the CPNT. The collaboration of hydrogen bonds, electrostatic and van der Waals interactions change the pulling force and lead to transport glucose through the CPNT. Potential of mean force (PMF) calculations revealed that the glucose has a minimum value of binding free energy and maximum configurational entropy in MPR regions. These findings can be used to design more CPNTs with different goals such as drug delivery. Communicated by Ramaswamy H. Sarma

description: AXL kinase has been over expressed in many tumors and its involvement in cell proliferation, migration, survival, and resistance makes the kinase as attractive therapeutic target for many cancers. In this study, we performed a virtual screening of the food and drug administration (FDA) approved drug molecule database against AXL kinase for repurposing studies of breast cancer. We have identified three non-cancer drugs with good binding energies were subjected to in vitro breast cancer MCF-7 cell lines. Three drug molecules showing the activity with good IC50 values toward the cancer cell line. We also carried out a 2 dimensional (2 D) quantitative structure activity relation (QSAR) studies on N-[4-(Quinolin-4-yloxy)phenyl]benzenesulfonamides derivatives to design potent inhibitors for AXL kinase. The final QSAR equation was robust with good predictivity and the statistical validation having R2 and Q2 values are 0.91 and 0.86, respectively. QSAR equation descriptors informs about the chemical properties of AXL inhibitors and helpful for designing novel inhibitors. Communicated by Ramaswamy H. Sarma

description: In the present study we generalize the self-consistent Hartree-Fock-Bogoliubov (HFB) theory formulated in the coordinate space to the case which incorporates an arbitrary mixing between protons and neutrons in the particle-hole (p-h) and particle-particle (p-p or pairing) channels. We define the HFB density matrices, discuss their spin-isospin structure, and construct the most general energy density functional that is quadratic in local densities. The consequences of the local gauge invariance are discussed and the particular case of the Skyrme energy density functional is studied. By varying the total energy with respect to the density matrices the self-consistent one-body HFB Hamiltonian is obtained and the structure of the resulting mean fields is shown. The consequences of the time-reversal symmetry, charge invariance, and proton-neutron symmetry are summarized. The complete list of expressions required to calculate total energy is presented.

description: 1 Studying how to deal with stereotypes and discrimination in a time of terror and despair: Theory and practice This contribution aims at exploring how Palestinian Arab and Jewish university students in Israel, attending a course on conflict resolution, deal with their stereotypical views of the Other and their prejudices, as well as their complex emotions of fear, hate, anxiety, and love. On the one hand, they have a natural desire for professional partnership and friendship with their fellow students. On the other hand, they are attending this class in a Jewish university, in the heart of the Middle East, where acts of terrorism occur almost daily. This violence changes the power structure and the dynamics of their mutual relationships. For most of them, this is the first time they have an unmediated interaction with the Other and this encounter is completely new for them. As well, they did not have any prior preparation for this challenging situation. This article analyzes how the activities entailed in conflict resolution – which begins as a planned, artificial and enforced process – is transformed into a personal journey in which the students get to know their individual and collective »self«, as well as the Other. It argues that management of the conflict can be perceived as a moral journey. More specifically, the research will focus on the conceptualization of the feelings, complicated experiences, and the way in which these students are required to confront the question of their authenticity.

description: This article focuses on finding the eigenvalues of the Laplacian matrix of the comaximal graph $Γ(\mathbb Z_n)$ of the ring $\mathbb Z_n$ for $n> 2$. We determine the eigenvalues of $Γ(\mathbb Z_n)$ for various $n$ and also provide a procedure to find the eigenvalues of $Γ(\mathbb Z_n)$ for any $n> 2$. We show that $Γ(\mathbb Z_n)$ is Laplacian Integral for $n=p^αq^β$ where $p,q$ are primes and $α, β$ are non-negative integers. The algebraic and vertex connectivity of $Γ(\mathbb Z_n)$ have been shown to be equal for all $n> 2$. An upper bound on the second largest eigenvalue of $Γ(\mathbb Z_n)$ has been obtained and a necessary and sufficient condition for its equality has also been determined. Finally we discuss the multiplicity of the spectral radius and the multiplicity of the algebraic connectivity of $Γ(\mathbb Z_n)$. Some problems have been discussed at the end of this article for further research.

description: This report address considerations in the 1995 farm bill debate for rice, including market conditions, policy proposals, trade agreements, and the interactions between policy and markets for selected commodities. U.S. rice sector income has shown steady growth in recent years, reaching $2.1 billion in 1993/94. However, Government program payments have also grown in importance. Since 1985/86, rice program outlays have averaged $733 million per year, 42 percent of all returns from rice farming. Farm and industry economic health are linked to costs of production which vary significantly across the six rice-producing regions. Because of inflation in the cost of production since the early 1980s, frozen payment yields, reduced target prices, and continued reductions in farm program benefits due to budgetary pressures, some rice farmers have been operating at a loss. Any reductions in current rice program support levels would probably accelerate the trends of a declining number of U.S. rice farms, increasing farm size, and a shift of rice growing from the high-cost production regions along the gulf coast to the upper Delta States, while reducing both the participation rate and dependency on government program revenue.

description: Der Konflikt um Israel/Palästina erhitzt säkulare wie religiöse Gemüter. Persönlicher Glaube, kollektiv-religiöse Identität, europäische Geschichte sowie kulturell-gesellschaftliche und politische Entwicklungen greifen in einer unentwirrbaren Gemengelage ineinander. Sachliche Argumentation und grundlegende Reflexionen aber sind notwendig, um den zwei Ethnien und drei Glaubenstraditionen zwischen Jordan und Mittelmeer den je angemessenen Raum zuzusprechen und der globalen Bedeutung des Landes Rechnung zu tragen. Um Entwirrung zu ermöglichen, müssen politische, gesellschaftliche, kulturelle und religiöse Bereiche unterschieden werden. Zugleich bedarf es der Fähigkeit, sie angemessen miteinander in Beziehung zu setzen. Das Ziel ist, allen Betroffenen so weit gerecht zu werden, dass sie in diesem Land, das zum »Haus des Islam« gehört, den Christen heilig ist und für Juden Heimstätte vor Gott darstellt, eine Zukunft haben. Diese Zukunft aber wird kaum so aussehen, wie die meisten sie sich erhoffen, denn alle Parteien werden aneinander gebunden.

Observing Correlations Between Dark Matter Accretion and Galaxy Growth: I. Recent Star Formation Activity in Isolated Milky Way-Mass Galaxies

description: The correlation between fresh gas accretion onto haloes and galaxy star formation is critical to understanding galaxy formation. Different theoretical models have predicted different correlation strengths between halo accretion rates and galaxy star formation rates, ranging from strong positive correlations to little or no correlation. Here, we present a technique to observationally measure this correlation strength for isolated Milky Way-mass galaxies with $z < 0.123$. This technique is based on correlations between dark matter accretion rates and the projected density profile of neighbouring galaxies; these correlations also underlie past work with splashback radii. We apply our technique to both observed galaxies in the Sloan Digital Sky Survey as well as simulated galaxies in the UniverseMachine where we can test any desired correlation strength. We find that positive correlations between dark matter accretion and recent star formation activity are ruled out with $\gtrsim 85\%$ confidence. Our results suggest that star formation activity may not be correlated with fresh accretion for isolated Milky Way-mass galaxies at $z=0$ and that other processes, such as gas recycling, dominate further galaxy growth.

description: This report address considerations in the 1995 farm bill debate for honey, including market conditions, policy proposals, and the interactions between policy and markets for selected commodities. The U.S. Government has supported the price of honey since 1950 by providing market price stability to honey producers to encourage them to maintain honeybee populations sufficient to pollinate important agricultural crops. When honey support prices moved above the average domestic price in the early 1980s, domestic producers found it profitable to forfeit their honey to the Government while packers and industrial users imported lower priced honey for domestic use. Changes made in the program by the Food Security Act of 1985 reduced forfeitures of honey to the Government and made domestic honey competitive with imports. Consequently, imports declined from 138.2 million pounds in 1985 to 55.9 million in 1988. At the same time, Government takeover of forfeited honey declined from 98 million pounds in 1985 to 1.1-3.2 million pounds from 1989 through 1992. Expenditures and takeovers will decline even further in fiscal years 1994 and 1995 with amendments to the Appropriations Acts, which eliminated deficiency payments and loan forfeitures for 1994 and 1995 crop honey.
Smooth-Particle Phase Stability with density and density-gradient potentials

description: Stable fluid and solid particle phases are essential to the simulation of continuum fluids and solids using Smooth Particle Applied Mechanics. We show that density-dependent potentials, such as Phi=(1/2)Sum (rho-rho_0)^2, along with their corresponding constitutive relations, provide a simple means for characterizing fluids and that a special stabilization potential, Phi=(1/2)Sum (delrho)^2, not only stabilizes crystalline solid phases (or meshes) but also provides a surface tension which is missing in the usual density-dependent-potential approach. We illustrate these ideas for two-dimensional square, triangular, and hexagonal lattices.

description: This report address considerations in the 1995 farm bill debate for tobacco, including market conditions, policy proposals, trade agreements, and the interactions between policy and markets for selected commodities. U.S. tobacco production is likely to decline by the end of the 1990s. Accelerated antismoking activity, along with an increasing number of smoking restrictions and prohibitions and proposals to increase cigarette taxes, is weakening leaf demand. Also, ample world production at lower prices is hurting U.S. export prospects. Technological advances that permit production of an acceptable-quality cigarette with cheaper leaf are curtailing demand for U.S.-grown leaf. Furthermore, stagnant cigarette demand and trade barriers hold down U.S. export prospects, although the General Agreement on Tariffs and Trade should help soften declines in exports. This report provides an overview of the U.S. tobacco industry, reviews Federal tobacco programs, and examines issues and potential program changes.

description: The development of agricultural biotechnology offers the opportunity to increase crop production, lower farming costs, improve food quality and safety, and enhance environmental quality. This report describes the economic, scientific, and social factors that will influence the future of biotechnology in agriculture. The supply of biotechnology innovations and products will be affected by public policies and by expectations of producer and consumer demand for the products. The demand for biotechnology by farmers and food processors is derived from the expected profitability of using the technology as an input to production. Ultimately, the use of biotechnology in the farm sector will depend on consumer demand for the biotechnology-derived agricultural product.

description: This paper proposes quantum image reconstruction. Input-triggered selection of an image among many stored ones, and its reconstruction if the input is occluded or noisy, has been simulated by a computer program implementable in a real quantum-physical system. It is based on the Hopfield associative net; the quantum-wave implementation bases on holography. The main limitations of the classical Hopfield net are much reduced with the new, original -- quantum-optical -- implementation. Image resolution can be almost arbitrarily increased.

title: Analysis of the Zebrafish Segmentation Clock
Creators: name: Narayanan, Rachna
Publisher: name: The Open University
Year: 2018

description: In vertebrates, the repeating vertebrae in the vertebral column are the clearest indicators of the segmented body plan. The embryonic precursors of the vertebral column and skeletal musculature are bilaterally symmetric blocks of tissue flanking the notochord called somites. Somites are generated sequentially and periodically from an unsegmented tissue called the presomitic mesoderm (PSM) by a process called somitogenesis.

 Underlying the periodicity of somitogenesis are transcriptional oscillations of cyclic genes in the cells of the PSM. On a tissue level, these oscillations manifest as travelling waves, departing from the posterior and arresting in the anterior. The position of arrest prefigures the position of the new somite boundary. The molecular network that comprises the cyclic genes and their regulation in the PSM is termed the segmentation clock. Retinoic acid (RA) has been previously proposed to be a differentiation signal that acts to arrest the oscillations at the anterior of the PSM. This thesis shows the zebrafish RA catabolism mutant giraffe has an altered cyclic gene wave pattern, an observation that suggests that rather than stop their oscillations, cells tune their frequencies in response to RA signalling, introducing a novel function for RA in the zebrafish segmentation clock.

 In amniotes, the segmentation clock instructs the metamery of the vertebral column, but in zebrafish, the relationship is not established. This thesis demonstrates that the segmentation clock is not required in zebrafish for the development of a periodic vertebral column by using a novel segmentation clock mutant, thereby supporting a role for the notochord in the development of vertebral column metamery. Therefore, two periodic patterning processes establish zebrafish body pattern – one segments the somites and musculature, and the second segments the vertebral column.

 This thesis advances the understanding of the mechanisms of body pattern establishment by way of these novel insights.
