description: Non-destructive detection of photonic qubits will enable important applications in photonic quantum information processing and quantum communications. Here, we present an approach based on a solid-state cavity containing an ensemble of rare-earth ions. First a probe pulse containing many photons is stored in the ensemble. Then a single signal photon, which represents a time-bin qubit, imprints a phase on the ensemble that is due to the AC Stark effect. This phase does not depend on the exact timing of the signal photon, which makes the detection insensitive to the time-bin qubit state. Then the probe pulse is retrieved and its phase is detected via homodyne detection. We show that the cavity leads to a dependence of the imprinted phase on the {\it probe} photon number, which leads to a spreading of the probe phase, in contrast to the simple shift that occurs in the absence of a cavity. However, we show that this scenario still allows non-destructive detection of the signal. We discuss potential implementations of the scheme, showing that high success probability and low loss should be simultaneously achievable.

description: Philanthropy is the voluntary gift of resources from private wealth to promote charitable causes, projects or organizations. Based on original research and a review of the existing literature, the purpose of this paper is to provide a comprehensive overview of the philanthropic landscape in Britain and to explain how philanthropy serves as a force for good in society. It begins by introducing the types of actors operating in the philanthropic field; the often confusing array of donors, foundations and beneficiaries of different types and hues. It outlines the choices confronting philanthropists and the different organisations and tools that exist to facilitate, maximize and effectively utilize philanthropic giving. In the paper, you can also read about the motivations behind philanthropy and the wide range of causes philanthropists support. Philanthropy plays an important role in social innovation through the founding of new organisations and institutions. Large numbers of schools, libraries, hospitals, universities, churches, parks and gardens and community organizations have their roots in philanthropy. Tens of thousands of front-line charities, tackling deep-seated problems at home and abroad and improving the lives of millions of people, are sustained largely by the generosity of private individuals. Overall, the concise discussion of a complex topic makes this paper a valuable introductory guide for prospective philanthropists, third sector professionals, board members of charitable trusts and foundations, interested academics and anyone else interested in understanding how philanthropy works.

The analogous result had been previously established in dimensions $d=1,2$ using the convolution structure of the inequality at the lower endpoint (an even integer); we obtain the generalization by using tools from bilinear restriction theory.

description: We study the effects of friction on the scaling evolution of string networks in condensed matter and cosmological contexts. We derive a generalized `one-scale' model with the string correlation length $L$ and velocity $v$ as dynamical variables. In non-relativistic systems, we obtain a well-known $L\propto t^{1/2}$ law, showing that loop production is important. For electroweak cosmic strings, we show transient damped epoch scaling with $L\propto t^{5/4}$ (or, in the matter era, $L\propto t^{3/2}$). A low initial density implies an earlier period with $L\propto t^{1/2}$. For GUT strings, the approach to linear scaling $L\propto t$ is faster than previously estimated.

Distinct Nature of Orbital Selective Mott Phases Dominated by the Low-energy Local Spin Fluctuations

description: Quantum orbital selective Mott (OSM) transitions are investigated within dynamical mean-field theory based on a two-orbital Hubbard model with different bandwidth at half filling. We find two distinct OSM phases both showing coexistence of itinerant electrons and localized spins, dependent on whether the Hund's coupling is full or of Ising type. The critical values and the nature of the OSM transitions are efficiently determined by entanglement entropy. We reveal that vanishing of the Kondo energy scale evidenced by absence of local spin fluctuations at low frequency in local dynamical spin susceptibility is responsible for the appearance of non-Fermi-liquid OSM phase in Ising Hund's coupling case. We argue that this scenario can also be applied to account for emergent quantum non-Fermi liquid in one-band Hubbard model when short-range antiferromagnetic order is considered.

Lower Energy Consequences of an Anomalous High-Energy Neutrino Cross-Section

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A new strong-interaction has been postulated for neutrinos above ~10^{19} eV to explain the production of highest-energy cosmic ray events. We derive a dispersion relation relating the hypothesized high-energy cross-section to the lower-energy neutrino-nucleon elastic amplitude. Remarkably, we find that the real forward amplitude becomes anomalous seven orders of magnitude lower in energy than does the total cross-section. We discuss possible measurable consequences of this early onset of new neutrino physics, and conclude that a significantly enhanced elastic ν-N scattering rate may occur for the neutrino beams available at Fermilab and CERN.

The Gross-Neveu model and QCDs chiral phase transition

Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: Quantum chromodynamics has a rather complicated phase structure. The finite temperature, chiral phase structure depends on the number of flavours and to a large extent on the particular values of the fermion masses. For two massless flavours there is a true second order transition. It has been argued that this transition belongs to the universality class of the three-dimensional O(4) spin model. The arguments have been questioned recently, and the transition was claimed to be mean field behaved. In this lecture we discuss this issue at the example of the three-dimensional, parity symmetric Gross-Neveu model at finite temperature, with a large number N of fermions. At zero temperature there is a phase where parity is spontaneously broken. At finite temperature, this model has a parity restoring second order transition. It reveals considerable similarity to the QCD chiral phase transition. There are related questions here concerning the universality class. We solve this problem essentially by means of the following methods: Large N expansion, dimensional reduction in the framework of quantum field theory, and high order convergent series expansions about disordered lattice systems.

description: Smart Specialisation is closely associated with the concept of diversification. For a better understanding of Smart Specialisation, this paper examines one little-explored explanatory factor of technological diversification: cooperation within and between regions. Using Organisation for Economic Co-operation and Development (OECD) REGPAT data on co-applications for patents, the empirical analysis investigates the role of cooperation between organizations on technological diversification in 226 European regions over 10 five-year periods, 2000–13. Cooperation within and between regions emerges as an important determinant of regional diversification, but both forms of cooperation should evolve hand in hand – singly, each form may prove ineffective at boosting regional diversification.

description: We propose the concept of machine learning configuration interaction (MLCI) whereby an artificial neural network is trained on-the-fly to predict important new configurations in an iterative selected configuration interaction procedure. We demonstrate that the neural network can discriminate between important and unimportant configurations, that it has not been trained on, much better than by chance. MLCI is then used to find compact wavefunctions for carbon monoxide at both stretched and equilibrium geometries. We also consider the multireference problem of the water molecule with elongated bonds. Results are contrasted with those from other ways of selecting configurations: first-order perturbation, random selection and Monte Carlo configuration interaction. Compared with these other serial calculations, this prototype MLCI is competitive in its accuracy, converges in significantly fewer iterations than the stochastic approaches, and requires less time for the higher-accuracy computations.

description: We compute long distance effects on the photon energy spectrum in inclusive radiative decays of $B$ mesons using light-cone expansion and heavy quark effective theory. We show that for sufficiently high photon energy the leading nonperturbative QCD contribution is attributed to the distribution function. The distribution function is found to be universal in the sense that the same distribution function also encodes the leading nonperturbative contribution to inclusive semileptonic decays of $B$ mesons at large momentum transfer. Some basic properties of the distribution function are deduced in QCD. Ways of extracting the distribution function directly from experiment and their implications are discussed. The theoretically clean methods for the determination of $|V_{ts}|$ are described.

description: Escape behaviour is a common antipredator strategy of lizards. Here, we studied the effect of several variables predicted to have a potential effect on escape behaviour of lizards. Specifically, we measured the effects of starting distance (SD), distance to cover, sex–age and the observer’s head orientation on flight initiation distance (FID) in the common agama Agama agama. Agamas were approached in urban localities in Limbe city, Cameroon, where they were habituated to the presence of humans. We found no association between FID and SD, but individuals closer to potential cover had shorter FID than individuals farther from a refuge. Juveniles escaped later than adults, but no significant differences were found in the FID between adult males and females. Head direction of the approaching observer had no effect on FID. This is, to the best of our knowledge, the first study investigating factors affecting FID in common agamas, extending our knowledge on risk-related behaviour in lizards of Old World tropics.
Instability induced by recollimation in highly magnetised outflows

description: In the paradigm of magnetic acceleration of relativistic outflows, a crucial point is identifying a viable mechanism to convert the Poynting flux into the kinetic energy of the plasma, and eventually into the observed radiation. Since the plasma is hardly accelerated beyond equipartition, MHD instabilities are often invoked to explain the dissipation of the magnetic energy. Motivated by the fast variability that is shown by the gamma-ray flares of both AGN and PWNe, different authors have proposed the Poynting flux to be dissipated in a region where the flow is converging. Here we perform a linear stability analysis of ultra-relativistic, highly magnetised outflows with such a recollimation nozzle, showing that MHD instabilities are indeed induced by the convergence of the flow. The amplitude of the perturbations increases while recollimation gets stronger, and eventually diverges when the flow is focused to a single point. Hence, depending on the geometry of the outflow, instabilities excited while the flow is converging may play an important role to dissipate the magnetic energy of the plasma.

description: A search for pair-produced charged Higgs bosons is performed with the L3 detector at LEP using data collected at centre-of-mass energies between 192 and 202 GeV, corresponding to an integrated luminosity of 233.2 pb^-1. Decays into a charm and a strange quark or into a tau lepton and its neutrino are considered. The observed events are consistent with the expectations from Standard Model background processes. Including data taken at lower centre-of-mass energies, lower limits on the charged Higgs mass are derived at the 95% confidence level. They vary from 67.4 to 79.9GeV as a function of the H^+/- --> tau nu branching ratio.

description: In theory, a neural network can be trained to act as an artificial specification for a program by showing it samples of the programs executions. In practice, the training turns out to be very hard. Programs often operate on discrete domains for which patterns are difficult to discern. Earlier experiments reported too much false positives. This paper revisits an experiment by Vanmali et al. by investigating several aspects that were uninvestigated in the original work: the impact of using different learning modes, aggressiveness levels, and abstraction functions. The results are quite promising.

Propagation of innovations in networked groups.

Year: 2008

description: A novel paradigm was developed to study the behavior of groups of networked people searching a problem space. The authors examined how different network structures affect the propagation of information in laboratory-created groups. Participants made numerical guesses and received scores that were also made available to their neighbors in the network. The networks were compared on speed of discovery and convergence on the optimal solution. One experiment showed that individuals within a group tend to converge on similar solutions even when there is an equally valid alternative solution. Two additional studies demonstrated that the optimal network structure depends on the problem space being explored, with networks that incorporate spatially based cliques having an advantage for problems that benefit from broad exploration, and networks with greater long-range connectivity having an advantage for problems requiring less exploration.

description: We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we choose the 3-3-1 model. We consider a variety of processes: q anti-q -> Y^{++} Y^{--}, u anti-d -> Y^{++} Y^{-}, anti-u d -> Y^+ Y^{--}, q anti-q -> Y^{++} e^{-} e^{-}, q anti-q -> phi^{++} phi^{--}, u anti-d -> -> phi^{++} phi^{-}, and anti-u d -> phi^{+} phi^{--}, where Y and phi are vector and scalar bileptons, respectively. Given the present low-energy constraints, we find that at the Tevatron, vector bileptons are unobservable, while light scalar bileptons (M_phi <= 300 GeV) are just barely observable. At the LHC, the reach is extended considerably: vector bileptons of mass M_Y <= 1 TeV are observable, as are scalar bileptons of mass M_phi <= 850 GeV.

description: In Parts I-III we showed that the number of ways to place $q$ nonattacking queens or similar chess pieces on an $n\times n$ chessboard is a quasipolynomial function of $n$ whose coefficients are essentially polynomials in $q$. In this part we focus on the periods of those quasipolynomials. We calculate denominators of vertices of the inside-out polytope, since the period is bounded by, and conjecturally equal to, their least common denominator. We find an exact formula for that denominator of every piece with one move and of two-move pieces having a horizontal move. For pieces with three or more moves, we produce geometrical constructions related to the Fibonacci numbers that show the denominator grows at least exponentially with $q$.

description: Abstract: We examine here two Ecuadorian towns and the state's efforts to support their development through competitiveness initiatives. Neoliberal, economic globalization is often equated with the insecurities of market competition. However, economic policy makers do not foment competition as much as competitive advantage. Whereas competition requires individual know-how, competitive advantage often involves cooperating to improve the underlying factors that help whole groups of firms. In Ecuador, policies have sought to engineer competitive advantage by creating industrial clusters. In our study, the town of Atuntaqui embraced the idea of clusters, uniting firms to work with international consultants and the Ministry of Industry. The economy has improved, but wealth shows signs of consolidation. The comparative case is a mechanized indigenous craft economy in Otavalo. Exploring how Otavalo's development has generated a set of shared resources anchored in a market plaza, we argue that its economy is best understood as a cultural commons. The experiences of both places have shown that economic development must take explicit measures to defend such commons if the gains of strategic cooperation are to be sustained in the long run. Resumen: Examinamos dos ciudades en Ecuador y el esfuerzo llevado a cabo por el estado para apoyar su desarrollo a través de iniciativas basadas en la competitividad. La globalización económica neoliberal es asimilada con la inseguridad de los mercados competitivos. Sin embargo, los responsables de la política económica no fomentan la competencia tanto como la ventaja competitiva. Mientras que la competencia se relaciona con conocimientos prácticos individuales, la ventaja competitiva requiere de cooperación, con el fin de mejorar factores subyacentes que beneficien a grupos de firmas en su conjunto. Las políticas implementadas en Ecuador para generar ventajas competitivas se fundamentaron en la creación de clusters industriales. En nuestro estudio, la ciudad de Atuntaqui aplicó la idea de clusters a través de la unión de firmas para trabajar con consultores internacionales y el Ministerio de Industria. La economía ha mejorado y la riqueza muestra signos de estar consolidándose. El caso comparado es la economía de tipo artesanal, mecanizada e indígena en Otavalo. Explorando la forma como el desarrollo de Otavalo ha generado un conjunto de recursos comunes, anclados en una plaza de mercado, argumentamos que la mejor manera de comprender esta economía es como un espacio cultural. La experiencia de ambas ciudades muestra que el desarrollo económico debe tomar medidas explícitas para defender estos espacios culturales, si se busca que las ganancias de la cooperación estratégica sean sostenibles en el largo plazo.
Relic Neutrinos and Z-Resonance Mechanism for Highest Energy Cosmic Rays

description: The origin of the highest energy cosmic rays remains elusive. The decay of a superheavy particle (X) into an ultraenergetic neutrino which scatters from a relic neutrino or antineutrino at the Z-resonance has attractive features. Given the necessary X mass of 1014-1015 GeV, the required lifetime, 1015-1016 yr, renders model building a serious challenge, but three logical possibilities are considered: (1) X is a Higgs scalar in SU(15) belonging to high-rank representation, leading to power-enhanced lifetime; (2) a global X quantum number has exponentially suppressed symmetry breaking by instantons; and (3) with additional space dimension(s), localization of X within the real-world brane leads to Gaussian decay suppression, the most efficient of the suppression mechanisms considered.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A moderate extension of MSSM based on a left-right symmetric gauge group, within which hybrid inflation is `naturally' realized, is discussed. The mu problem is solved via a Peccei-Quinn symmetry. Light neutrinos acquire hierarchical masses by the seesaw mechanism. They are taken from the small angle MSW resolution of the solar neutrino puzzle and the SuperKamiokande data. The range of parameters consistent with maximal nu_mu-nu_tau mixing and the gravitino constraint is determined. The baryon asymmetry of the universe is generated through a primordial leptogenesis. The subrange of parameters, where the baryogenesis constraint is also met, is specified. The required values of parameters are more or less `natural'.

description: The chapter reviews the syntax to store machine-readable annotations and describes the mapping between rule-based modelling entities (e.g., agents and rules) and these annotations. In particular, we review an annotation framework and the associated guidelines for annotating rule-based models of molecular interactions, encoded in the commonly used Kappa and BioNetGen languages, and present prototypes that can be used to extract and query the annotations. An ontology is used to annotate models and facilitate their description.

Using a sample of 9.7 times 10^{6} B-Bbar pairs collected with the CLEO detector operating at the Cornell Electron Storage Ring, we measure the branching fractions B(B^0 \to D^{*-} proton antiproton π^+) = ({6.5}^{+1.3}_{-1.2} +- 1.0) \times 10^{-4} and B(B^0 \to D^{*-} proton antineutron) = ({14.5}^{+3.4}_{-3.0} +- 2.7) times 10^{-4}. Antineutrons are identified by their annihilation in the CsI electromagnetic calorimeter.

description: We investigate the critical dynamics of the Hybrid Monte Carlo algorithm approaching the chiral limit of standard Wilson fermions. Our observations are based on time series of lengths O(5000) for a variety of observables. The lattice sizes are 16^3 x 32 and 24^3 x 40. We work at beta=5.6, and kappa=0.156, 0.157, 0.1575, 0.158, with 0.83 > m_pi/m_rho > 0.55. We find surprisingly small integrated autocorrelation times for local and extended observables. The dynamical critical exponent $z$ of the exponential autocorrelation time is compatible with 2. We estimate the total computational effort to scale between V^2 and V^2.25 towards the chiral limit.

description: The purpose of this article is to provide a preliminary overview of the common evidence on the main issues identified by the CREA team, focusing specifically on different value chains in Ghana and Vietnam (D.4.2). It also emphasizes the need for further study on Voluntary Sustainability Standards (VSSs), which the literature has shown deserve consideration when designing policies and programs aimed at improving various aspects of the livelihoods of smallholder farmers, including labor rights, gender equality, adoption of sustainable practices, and biodiversity promotion (D.4.3). These considerations are particularly relevant in the light of the Agenda for Sustainable Development (UN, 2015).

description: Chronic HBV infection is a worldwide public health concern. It is characterized by the persistence of the hepatitis B surface antigen (HBsAg) in serum for more than six months. The persistence of HBsAg is mediated by viral covalently closed circular DNA (cccDNA) in the nuclei of infected cells. Although several genome-editing techniques have demonstrated the possibility to inhibit HBV viral replication, attempts to completely clear nuclear cccDNA remain unsuccessful. Recent studies have suggested the possibility to use the Clustered Regularly Interspaced Short Palindromic Repeats system (CRISPR/Cas9) to suppress HBV infection; however, effective delivery of this tool for in vivo targeting is a major issue. To examine the possibility to utilize the CRISPR/Cas9 system for HBV clearance, we plan to generate a mouse model of chronic HBV infection by using a recombinant Adeno-associated virus that expresses HBV (rAAV-HBV). It has been previously suggested that a rAAV-HBV virus can establish persistent HBV infection in mice. We would like to use this model to test whether viral vectors that carry HBV-specific CRISPR/Cas9 can target HBV cccDNA in vivo. To this end, the recombinant AAV-HBV virus was produced by an AAV helper free expression system in HEK293T cells. As a control, I also produced a rAAV-GFP virus from co-transfection of HEK293T cells. My results show that the recombinant AAV-GFP virus can effectively infect human liver HepG2 cells and express high levels of green fluorescent protein. I also examined the rAAV-HBV virus for expressing HBV genes in HepG2 cells by western blot and quantitative real-time PCR (qPCR). While western blots showed defined bands of HBsAg in HepG2 cells, qPCR of infected HepG2 culture supernatants and cell lysates yielded a low amount of HBV genomes. We therefore demonstrated the possibility to use rAAV-HBV vector to delivery HBV genome into liver cells. However, the efficiency is relatively low, likely resulting from the large size of the HBV genome that may affect the AAV packaging efficiency. Multiple approaches to improve the efficiency of the rAAV-HBV vector are currently being tested.
