The shortest disjunctive normal forms of Boolean functions by reducing the number of arguments
Creators: name: Yung, Ho Sen
Publisher: name: University of British Columbia
Year: 2009

description: Denoting the length of a shortest disjunctive normal form of a Boolean function / by l(f), this thesis provides a way to express l(f) in terms of l(g) for some Boolean function g with no more arguments than f and with the same number of zeros as f . This method is useful for finding the shortest disjunctive normal forms of Boolean functions f with few zeros. It also gives explicitly the values of l(f) for f with three or fewer zeros, and some bounds for l(f) for a certain class of Boolean functions f . For n much larger than k, the zeros of a Boolean function f of n arguments with k zeros have the property that for some large subsets P = {i₁,i₂,…,i[sub d]} of {1,2,..., n} and 1 ≤ c ≤ d, all k zeros s satisfy Si₁ = Si₂ = ... = Si[sub c] = Si[sub c]+1 = Si[sub c]+2 = ... = Si[sub d]. Thus, one may consider all dimensions in each P as a single dimension and construct a corresponding Boolean function g with fewer arguments.
Reducing the Probability of Capture into Resonance

description: A migrating planet can capture planetesimals into mean motion resonances. However, resonant trapping can be prevented when the drift or migration rate is sufficiently high. Using a simple Hamiltonian system for first and second order resonances, we explore how the capture probability depends on the order of the resonance, drift rate and initial particle eccentricity. We present scaling factors as a function of the planet mass and resonance strength to estimate the planetary migration rate above which the capture probability drops to less than 1/2. Applying our framework to multiple extra solar planetary systems that have two planets locked in resonance, we estimate lower limits for the outer planet's migration rate allowing resonance capture of the inner planet. Mean motion resonances are comprised of multiple resonant subterms. We find that the corotation subterm can reduce the probability of capture when the planet eccentricity is above a critical value. We present factors that can be used to estimate this critical planet eccentricity. Applying our framework to the migration of Neptune, we find that Neptune's eccentricity is near the critical value that would make its 2:1 resonance fail to capture twotinos. The capture probability is affected by the separation between resonant subterms and so is also a function of the precession rates of the longitudes of periapse of both planet and particle near resonance.

description: This paper evaluates complementarities of labor market institutions and the business cycle in the context of a stochastic dynamic general equilibrium model economy. Matching between workers and vacancies with endogenous time spent in search, Nash-bargained wages, payroll taxation, and differential support for unemployed labor in search and leisure are central aspects of the model. For plausible regions of the policy and institutional parameter space, the model exhibits more persistence than standard RBC models and can exhibit indeterminacy of rational expectations paths without increasing returns in production. Furthermore, labor market institutions act in a complementary fashion in generating these effects.

description: Applications relying on mid-infrared radiation (Mid-IR, $λ\sim$ 3-30 $μ$m) have progressed at a very rapid pace in recent years, stimulated by scientific and technological breakthroughs. Mid-IR cameras have propelled the field of thermal imaging. And the invention of the quantum cascade laser (QCL) has been a milestone, making compact, semiconductor-based mid-IR lasers available to a vast range of applications. All the recent breakthrough advances stemmed from the development of a transformative technology. In addition to the generation and detection of light, a key functionality for most photonics systems is the electrical control of the amplitude and/or phase of an optical beam at ultra-fast rates (GHz or more). However, standalone, broadband, integrated modulators are missing from the toolbox of present mid-IR photonics integrated circuits and systems developers. We have developed a free-space amplitude modulator for mid-IR radiation ($λ\sim$ 10 $μ$m) that can operate up to at least 1.5 GHz (-3dB cut-off at $\sim$ 750 MHz) and at room-temperature. The device relies on a semiconductor hetero-structure enclosed in a judiciously designed metal-metal optical resonator. At zero bias, it operates in the strong light-matter coupling regime up to 300K. By applying an appropriate bias, the device transitions to the weak coupling regime. The large change in reflectivity due to the disappearance of the polaritonic states is exploited to modulate the intensity of a mid-IR continuous-wave laser up to speeds of more than 1.5 GHz.

In other cases there are no bulk tachyons, but there are localized tachyons. The real time condensation of these localized tachyons is described by an exactly solvable worldsheet CFT. We also find some stable, non-supersymmetric backgrounds.

description: Do preferences for income inequality differ systematically between the post-socialist countries of Central and Eastern Europe and the Western established market economies? This paper analyses 1999 data from a large international survey to address this question. In particular, we examine whether attitudes to inequality differ between East and West even after the "conventional" determinants of attitudes are controlled for. Results suggest that this is indeed the case. A decade after the breakdown of communism, people in transition countries are indeed significantly more "egalitarian" than those living in the West, in the sense that they are less willing to tolerate existing income inequalities, even after the actual level of income inequality and other determinants of attitudes are taken into account. These results do not seem to be driven by a recent change in attitudes owing to a rapid rise in inequality during transition, but rather appear to constitute an attitudinal legacy carried over from socialism. This is very likely to have important implications for the political support of reform policy, in particular for the political feasibility of future welfare state reforms in these countries. Unterscheiden sich die Präferenzen für Einkommensungleichheit systematisch zwischen den Transformationsländern Mittel- und Osteuropa im Vergleich zu den etablierten Marktwirtschaften Westeuropas? Dieses Papier analysiert die Ergebnisse einer grossen internationalen Umfrage aus dem Jahre 1999. Insbesondere wird untersucht, ob sich die Einstellungen zum Thema Ungleichheit in Ost und West unterscheiden, nachdem für die "konventionellen" Determinanten dieser Einstellungen kontrolliert wurde. Die Ergebnisse zeigen, dass dies in der Tat der Fall ist. Zehn Jahre nach dem Zusammenbruch des Kommunismus weist die Bevölkerung in den Transformationsländern eine significant "egalitärere" Haltung auf als jene im Westen, insofern als sie weniger tolerant sind gegenüber gegenwärtiger Einkommensungleichheiten, selbst nachdem für das tatsächliche Niveau der Einkommensungleichheit sowie andere Einflussfaktoren kontrolliert wurde. Diese Ergebnisse scheinen auch nicht auf den relativ starken Anstieg der Ungleichheit während der Transformation zurückzuführen zu sein, sondern können eher als ein Erbe aus der sozialistischen Zeit betrachtet werden. Dies hat wesentliche Implikationen für den Grad an politischer Unterstützung zukünftiger Reformpolitik, insbesondere die politische Umsetzbarkeit von Reformen des Wohlfahrtsstaats in den Transformationsländern.

description: Using "complexity=action" proposal we study the late time growth rate of holographic complexity for nonlinear charged Lifshitz black hole with a single horizon or two horizons. As a toy model, we consider two kinds of such black holes: nonlinear charged Lifshitz black hole and nonlinear logarithmic charged Lifshitz black hole. We find that for the black hole with two horizons, the action growth bound is satisfied. But for the black hole with a single horizon, whether the Lloyd bound is violated depends on the specific value of dimensionless coupling constants $β_{1},β_{2}$, spacetime dimension $D$ and dynamical exponent $z$.

description: In "The Dawn of Everything," David Graeber and David Wengrow (2021) unearth certainties held regarding the social evolution of humankind, which supposedly began with the Neolithic revolution and – following a linear trajectory – resulted in modern state-building. The book is not about migration at all by its making, and yet mobility plays a vital part in the authors’ account. It imparts two vital lessons to migration research. The first concerns the role and function of migration as such. The second concerns the role of schismogenesis. Both conceptualizations are not new to migration studies, but they emphasize essential insights. By applying both concepts, migration as freedom and schismogenesis, to my own research project, I will attempt to dismantle the notion of the migrant subject.

description: The countries wishing to join the EU have a high potential for low cost greenhouse gas emission reduction. As they cannot join the "bubble" agreement for the first commitment period of the Kyoto Protocol, project-based Joint Implementation (JI) could be a powerful strategy to integrate accession countries into an overall EU climate policy strategy. An important question in this context is whether the "acquis communautaire" will be used to define the baseline for the calculation of emission reductions from JI projects. A problem is that the grace periods for several environmental sectors, e.g. for application of the IPPC directive, differ considerably among countries. The EU should help accession countries to establish a predictable legal framework on which to base JI preventing in this way the current legal uncertainty regarding procedures of JI. Moreover, it should aim at an early implementation of the monitoring guideline and couple it with technical assistance. This would allow to build strong inventory systems in the accession countries and thus avoid the risk that JI is restricted to the second, strongly supervised track. In den Ländern, die der EU in den nächsten Jahren beitreten wollen, gibt es ein erhebliches Potenzial kostengünstiger Maßnahmen zur Treibhausgasverringerung. Da die Beitrittsländer der EU-Zielgemeinschaft für die 1. Verpflichtungsperiode des Kyoto- Protokolls nicht beitreten können, könnte projektbasierte Joint Implementation (JI) eine wichtige Strategie zur Integration dieser Länder in eine EU-weite Klimapolitikstrategie sein. Eine wichtige Frage ist in diesem Zusammenhang, ob der "Acquis Communautaire" die Referenzfälle für die Berechnung der Emissionsverringerung aus JI-Projekten bestimmt. Problematisch hierbei ist, dass sich die Übergangsperioden für verschiedene Sektoren, z.B. für die Anwendung der IVU-Richtlinie, zwischen den Ländern erheblich unterscheiden. Die EU sollte den Ländern bei dem Aufbau eines Rechtsrahmens für JI unterstützen, um die derzeitige rechtliche Ungewissheit zu beseitigen. Außerdem sollte sie eine frühzeitige Umsetzung der Berichterstattungs- Richtlinie anstreben und dies mit technischer Hilfe verknüpfen. Somit könnten gute Inventarsysteme aufgebaut werden und ausgeschlossen werden, dass JI auf den zweiten, kontrollintensiven Weg eingeschränkt wird.

description: We study stochastic tree fluid networks driven by a multidimensional Levy process. We are interested in (the joint distribution of) the steady-state content in each of the buffers, the busy periods, and the idle periods. To investigate these fluid networks, we relate the above three quantities to fluctuations of the input Levy process by solving a multidimensional Skorokhod reflection problem. This leads to the analysis of the distribution of the componentwise maximums, the corresponding epochs at which they are attained, and the beginning of the first last-passage excursion. Using the notion of splitting times, we are able to find their Laplace transforms. It turns out that, if the components of the Levy process are `ordered', the Laplace transform has a so-called quasi-product form. The theory is illustrated by working out special cases, such as tandem networks and priority queues.

description: Japan's markets for money, capital and foreign exchange are among the biggest worldwide. For many years, Tokyo's role as the leading financial center in Asia has been unchallenged. However, recently, other places in the region such as Singapore and Hong Kong have invested heavily to strengthen their competitiveness, and countries like Malaysia and Thailand stand in line to follow their example. This raises two questions: First, how can the emergence of financial centers be explained in general? Second, what are Tokyo's longer-term prospects and how are they affected by the various influences? The study draws the attention to the role of evolutionary forces and the way by which micromotives and the interaction of many agents produces macrobehavior. In this preliminary paper representing a very early stage of research, financial markets are considered as emergent systems characterised by a high degree of complexity. Starting from an analysis of the strengths and weaknesses of a basic concept of the New Economic Geography possible alternatives to capture the idea of evolving financial markets are discussed. Then a tentative classification of financial places in Asia and, in particular, Tokyo's future role is given. Japans Finanzmärkte zählen zu den größten der Welt. Lange Zeit erschien die Rolle Tokios als führendes Finanzzentrum Ostasiens unumstritten. In den letzten Jahren haben jedoch in einigen Ländern der Region alte und neue Märkte begonnen, verstärkt in Wettbewerb dazu zu treten. Das wirft die Frage auf, welche Faktoren generell die Entwicklung von Finanzzentren beeinflussen und in welcher Weise insbesondere Tokio davon betroffen ist. Die folgende Studie, die höchst vorläufiger Natur ist und die Forschungsarbeit in einem sehr frühen Stadium darstellt, lenkt die Aufmerksamkeit auf die Bedeutung evolutionärer Veränderungen. Finanzmärkte werden hier als emergente Systeme betrachtet, die durch ein hohes Maß an Komplexität gekennzeichnet sind. Ausgangspunkt der Analyse ist eine Beschreibung der Stärken und Schwächen eines Ansatzes aus der Neuen Ökonomischen Geographie zur Erklärung von Agglomeration, die Weiterentwicklung seiner grundlegenden Ideen und die Untersuchung, in welcher Weise sich diese auf die Evolution von Finanzmärkten anwenden lassen. Daran schließt sich der Versuch einer vorläufigen Klassifikation von Finanzplätzen in Asien an, bei der besonderes Augenmerk auf Tokios zukünftige Rolle in der Region gerichtet ist.

description: Recent numerical analyses to optimize the design of microfluidic devices for more effective entrapment or segregation of surrogate circulating tumor cells (CTCs) from healthy cells have been reported in the literature without concurrently accommodating the non-Newtonian nature of the body fluid and the non-uniform geometric shapes of the CTCs. Through a series of two-dimensional proof-of-concept simulations with increased levels of complexity (e.g., number of particles, inline obstacles), we investigated the validity of the assumptions of the Newtonian fluid behavior for pseudoplastic fluids and the circular particle shape for different-shaped particles (DSPs) in the context of microfluidics-facilitated shape-based segregation of particles. Simulations with a single DSP revealed that even in the absence of internal geometric complexities of a microfluidics channel, the aforementioned assumptions led to 0.11-0.21W (W is the channel length) errors in lateral displacements of DSPs, up to 3-20% errors in their velocities, and 3-5% errors in their travel times. When these assumptions were applied in simulations involving multiple DSPs in inertial microfluidics with inline obstacles, errors in the lateral displacements of DSPs were as high as 0.78W and in their travel times up to 23%, which led to different (un)symmetric flow and segregation patterns of DSPs. Thus, the fluid type and particle shape should be included in numerical models and experiments to assess the performance of microfluidics for targeted cell (e.g., CTCs) harvesting.

description: This study examines performance gaps among foreign-owned and domestically-owned Austrian firms. In line with earlier findings our results suggest that the positive effects of participating in a foreign multinational's network can mainly be found in productivity and profitability. A further distinction between purely national firms and multinational enterprises (MNEs) reveals that both gaps derive from gains of MNE networks rather than from ownership per se. Regardless of ownership, MNEs are more similar than MNEs and purely national firms. Gaps concerning the investment propensity and growth are primarily explained by firm characteristics rather than foreign ownership. There is no evidence of an additional bonus resulting from closer cultural proximity of German-owned firms. Diese Studie untersucht Unterschiede in der Performance auslandskontrollierter und heimischer Unternehmen in Österreich. Die Ergebnisse bestätigen insofern frühere Untersuchungen, als die wichtigsten Vorteile auslandskontrollierter Unternehmen in der überlegenen Produktivität und Rentabilität gesehen werden. Bei Unterscheidung der österreichischen Firmen in rein nationale und multinationale Firmen (MNE) zeigt sich, daß österreichische und ausländische MNE einander ähnlicher sind als die österreichischen MNE und rein nationale Firmen. Die aufgezeigten Performance- Unterschiede resultieren eher aus der Einbindung in MNE-Netzwerke als aus dem Auslandseigentum an sich. Unterschiedliche Investitionsneigung und Wachstumsverläufe lassen sich primär durch unternehmensspezifische Faktoren und weniger durch das Auslandseigentum erklären. Es ergeben sich keine Anhaltspunkte für einen zusätzlichen Performance-Vorsprung deutscher Investoren aus deren kultureller Nähe zu Österreich.

Turbulence Generation by Substructure Motion in Clusters of Galaxies

description: Clusters of galaxies form through major merger and/or absorption of smaller groups. In fact, some characteristic structures such as cold fronts, which are likely relevant to moving substructures, are found by {\it Chandra}. It is expected that moving substructures generate turbulence in the intracluster medium (ICM). Such turbulence probably plays a crucial role in mixture and transport of gas energy and heavy elements, and particle acceleration. The {\it Astro-E2} satellite, which is planned to be launched in 2005, will detect broadened lines due to turbulent motion. In order to explore the above-mentioned issues, it is important to investigate the generation processes and structure of ICM turbulence. We investigate the ICM dynamical evolution in and around a moving substructure with three-dimensional hydrodynamical simulations. Eddy-like structures develop near the boundary between the substructure and the ambient ICM through Kelvin-Helmholtz instabilities. Because of these structures, characteristic patterns appear in the line-of-sight velocity distribution of the ICM.

description: The 2175 Å ultraviolet (UV) extinction bump in interstellar medium (ISM) of the Milky Way was discovered in 1965. After intensive exploration of more than a half century, however, its exact origin still remains a big conundrum that is being debated. Here we propose a mixture model by which the extinction bump in ISM is argued possibly relevant to the clusters of hydrogenated T-carbon (HTC) molecules (C40H16) that have intrinsically a sharp absorption peak at the wavelength 2175 Å. By linearly combining the calculated absorption spectra of HTC mixtures, graphite, MgSiO3 and Fe2SiO4, we show that the UV extinction curves of optional six stars can be nicely fitted. This present work poses an alternative explanation toward understanding the physical origin of the 2175 Å extinction bump in ISM of the Milky Way.

description: Falling among the elderly is a serious concern that affects many seniors. In France, around 450,000 falls are record-ed per year, resulting in 9,300 deaths, which equates to 11.2% of all-cause mortality in the elderly. In this RID study, we consider the activity of detection, alert and action following a fall for a French elderly person over 65 and living at home (not in an eldercare). The goal is to simply compare commercial solutions for effectively detecting, alerting, and starting a safety action after a fall.

The overall performance of solutions on the effectiveness metric is worryingly low. In this situation, the RID comparator tells us that the Active wristband/pendant Sigfox solution is the most adapted solution of the market.

description: Applying the general question of aid effectiveness to the sector of education, this paper reveals an overall positive effect of development assistance on primary enrolment. However, even the most optimistic estimates clearly show that at any realistic rate of growth, aid will never be able to move the world markedly closer towards the internationally agreed objective of education for all. Universal primary education requires increased efficiency of educational spending by donors and national governments alike. Moreover, the recipient countries' general political and institutional background matters. Under conditions of bad governance, the impact of aid on enrolment can actually turn negative.

Se diseñó cómo medir el valor de este blog como herramienta educativa y recalqué la creación de una comunidad virtual de aprendizaje dado el posible uso en cursos posteriores de los trabajos difundidos en distintos formatos y géneros en las aulas; y la potenciación de los cv de los futuros alumnos a la hora de solicitar empleo. Este blog facilita la docencia universitaria en periodismo, como referente de calidad para los alumnos y como herramienta docente. Y con cada género periodístico difundido puede comprobarse que en las aulas UEMC se trabajan también metodologías como el aprendizaje por descubrimiento y el método de investigación o la enseñanza por medio del conflicto cognitivo con los artículos de opinión, etc.

description: CP violation in $B\to J/ψK^*$ decays is studied using an angular analysis in a data sample of 253 fb$^{-1}$ recorded with the Belle detector at the KEKB $e^+e^-$ collider. The flavor separated measurements of the decay amplitudes indicate no evidence for direct CP violation. T-odd CP violation is studied using the asymmetries in triple product correlations, and the results are consistent with the Standard Model null predictions. The time-dependent angular analysis gives the following values of CP violating parameters: $\sin 2ϕ_1 = 0.24 \pm 0.31 \pm 0.05$ and $\cos 2ϕ_1 = 0.56 \pm 0.79 \pm 0.11$.

description: We extend exact deterministic remote state preparation (RSP) with minimal classical communication to quantum systems of continuous variables. We show that, in principle, it is possible to remotely prepare states of an ensemble that is parameterized by infinitely many real numbers, i.e., by a real function, while the classical communication cost is one real number only. We demonstrate continuous variable RSP in three examples using (i) quadrature measurement and phase space displacement operations, (ii) measurement of the optical phase and unitaries shifting the same, and (iii) photon counting and photon number shift.

description: A whole bundle of so-called "flexible mechanisms" has been foreseen by the Kyoto Protocol in order to help industrial countries to fulfill their agreed reduction targets in the most cost-effective way. Emission permits will act as the backbone of all market-orientated mechanisms. Therefore, their initial allocation to the market participants is crucial. The deposit-refund model of Central Allocation is an alternative to the distribution of emission permits actually discussed in the context of flexible mechanisms. A Climate Bank is proposed that issues permits equal to the aggregate budget of all Annex-B countries. The system of Central Allocation is aimed to achieve an equitable distribution according to real emission needs, a positive sanction for compliance and overall system integrity.
Optimising repeater schemes for the quantum internet

description: The rate at which quantum communication tasks can be performed using direct transmission is fundamentally hindered by the channel loss. Quantum repeaters allow, in principle, to overcome these limitations, but their introduction necessarily adds an additional layer of complexity to the distribution of entanglement. This additional complexity - along with the stochastic nature of processes such as entanglement generation, Bell swaps, and entanglement distillation - makes finding good quantum repeater schemes non-trivial. We develop an algorithm that can efficiently perform a heuristic optimisation over a subset of quantum repeater schemes for general repeater platforms. We find a strong improvement in the generation rate in comparison to an optimisation over a simpler class of repeater schemes based on BDCZ repeater schemes. We use the algorithm to study three different experimental quantum repeater implementations on their ability to distribute entanglement, which we dub \emph{information processing} implementations, \emph{multiplexed} implementations, and combinations of the two. We perform this heuristic optimisation of repeater schemes for each of these implementations for a wide range of parameters and different experimental settings. This allows us to make estimates on what are the most critical parameters to improve for entanglement generation, how many repeaters to use, and which implementations perform best in their ability to generate entanglement.

description: In this paper, we investigate internationalization strategies of German manufacturing firms in the European Union. We give reasons for the hypothesis that traditional market strategies had been replaced by border-crossing production networking based on the comparative advantage of host countries and on specialisation and scale economies. Our empirical test of this hypothesis shows, on the one hand, that traditional market strategies are not outdated. On the other hand, there are clear signs of international network strategies. They form an important component in internationalization strategies of multinationals in the Internal Market. The location of foreign production of German multinationals is, among others, oriented towards the technological potential of host countries indicating the importance of asset-seeking strategies. Furthermore, the positive connection between foreign production and both exports and imports points at the significance of efficiency-oriented strategies with foreign affiliates taking over an active part and not only being recipient of components of the German parent companies. However, there is hardly evidence that significant changes towards network strategies took place between 1996 and 2000.
Calibrating head-coupled virtual reality systems
Creators: name: Stevenson, Alexander
Publisher: name: University of British Columbia
Year: 2009

description: Head-tracking virtual environments are difficult to implement because of the need to calibrate such systems accurately, as well as the difficulty in computing the correct off-axis image for a given eye location. The situation is further complicated by the use of multiple screens, the need to change the calibration for different users, and the desire to write portable software which can be reused on different hardware with varying screen configurations. This, thesis presents a solution to these problems, allowing greatly simplified development of head-tracking software. By making use of-the head-tracking sensors built into the environment, we can quickly and accurately calibrate not only userspecific measurements, such as eye-positions, but also system measurements, such as the size and locations of display screens. A method of doing this calibration is developed, as well as a software library which will read a system configuration and integrate with OpenGL to compute correct off-axis projections for a user's viewing position. The calibration makes use of a novel "sighting" technique which has the great advantage of accurately finding the true rotational centre of a user's eyes. To complement this, the software library includes functions which predict the optical centre of a user's eye based on a given gaze point. As a demonstration of both the calibration method and the utility library, a hardware rendering application is discussed. This application performs the real-time rendering of view-dependent LaFortune reflectance functions in graphics hardware. As with all view-dependent lighting methods, both the viewing angle and position of the light are taken into account while rendering. Head-coupling allows the system to use the user's true viewing direction in the lighting computation, and the position of the virtual light is controlled by a 3D sensor in the user's hand. The method in which the view-dependent lighting model is implemented in hardware is explained, as well as possible improvements. Throughout, the Polhemus FASTRAK is used as the tracking system, though all the results are easily applicable to any six degree-of-freedom tracking system.
The Noncoherent Rician Fading Channel -- Part I : Structure of the Capacity-Achieving Input

description: Transmission of information over a discrete-time memoryless Rician fading channel is considered where neither the receiver nor the transmitter knows the fading coefficients. First the structure of the capacity-achieving input signals is investigated when the input is constrained to have limited peakedness by imposing either a fourth moment or a peak constraint. When the input is subject to second and fourth moment limitations, it is shown that the capacity-achieving input amplitude distribution is discrete with a finite number of mass points in the low-power regime. A similar discrete structure for the optimal amplitude is proven over the entire SNR range when there is only a peak power constraint. The Rician fading with phase-noise channel model, where there is phase uncertainty in the specular component, is analyzed. For this model it is shown that, with only an average power constraint, the capacity-achieving input amplitude is discrete with a finite number of levels. For the classical average power limited Rician fading channel, it is proven that the optimal input amplitude distribution has bounded support.

description: We consider the effect of exact gluon kinematics in the virtual photon-gluon impact factor at small x. By comparing with fixed order DIS scheme splitting and coefficient functions, we show that the exact kinematics results match the fixed order results well at each order, which suggests that they allow for an accurate NLL analysis of proton structure functions. We also present, available for the first time, x-space parameterisations of the NNLO DGLAP splitting functions in the DIS scheme, and also the longitudinal coefficients for neutral current scattering.

description: We make three related contributions motivated by the challenge of training stochastic neural networks, particularly in a PAC-Bayesian setting: (1) we show how averaging over an ensemble of stochastic neural networks enables a new class of \emph{partially-aggregated} estimators; (2) we show that these lead to provably lower-variance gradient estimates for non-differentiable signed-output networks; (3) we reformulate a PAC-Bayesian bound for these networks to derive a directly optimisable, differentiable objective and a generalisation guarantee, without using a surrogate loss or loosening the bound. This bound is twice as tight as that of Letarte et al. (2019) on a similar network type. We show empirically that these innovations make training easier and lead to competitive guarantees.
