description: We associate to a perturbation $(f_t)$ of a (stably mixing) piecewise expanding unimodal map $f_0$ a two-variable fractional susceptibility function $Ψ_ϕ(η, z)$, depending also on a bounded observable $ϕ$. For fixed $η\in (0,1)$, we show that the function $Ψ_ϕ(η, z)$ is holomorphic in a disc $D_η\subset \mathbb{C}$ centered at zero of radius $>1$, and that $Ψ_ϕ(η, 1)$ is the Marchaud fractional derivative of order $η$ of the function $t\mapsto \mathcal{R}_ϕ(t):=\int ϕ(x)\, dμ_t$, at $t=0$, where $μ_t$ is the unique absolutely continuous invariant probability measure of $f_t$. In addition, we show that $Ψ_ϕ(η, z)$ admits a holomorphic extension to the domain $\{ (η, z) \in {\mathbb{C}}^2\mid 0<\Re η<1, \, z \in D_η\}$. Finally, if the perturbation $(f_t)$ is horizontal, we prove that $\lim_{η\to 1}Ψ_ϕ(η, 1)=\partial_t \mathcal{R}_ϕ(t)|_{t=0}$.

Psicologia e potere in Im Westen nichts Neues. Una lettura del romanzo di Remarque a partire da Freud
Creators: name: Fossaluzza, Cristina
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: In 1915, a few months after the outbreak of the 1st World War, Sigmund Freud writes the essay Zeitgemäßes über Krieg und Tod, in which he reflects about the reason why war is still possible in a cultural advanced society like the western one, and about the relation of modernity with the problem of “evil”, violence and death. This article takes its cue from this essay in order to analyse Erich Maria Remarque's novel Im Westen nichts Neues (1928-29) from an innovative point of view. Remarque himself argues in many interviews and articles that his book should neither be considered a historical report about the 1st World War nor merely an antiwar-novel about the dramatic experience of a lost generation, but rather a true psychological novel. As a matter of fact, Im Westen nichts Neues tells about the “human all too human” mechanisms of violence and power through an understated representation of the trauma of a generation which was thrown into a sort of “state of exception”, a state situated simultaneously outside and inside civil society. The essay aims to illustrate how Freud and Remarque take a very similar perspective in their works about the Great War when considering the complex relation between culture and war, civilisation and violence, psychology and power in western modern society.

description: We review the concept of support vector machines (SVMs) and discuss examples of their use. One of the benefits of SVM algorithms, compared with neural networks and decision trees is that they can be less susceptible to over fitting than those other algorithms are to over training. This issue is related to the generalisation of a multivariate algorithm (MVA); a problem that has often been overlooked in particle physics. We discuss cross validation and how this can be used to improve the generalisation of a MVA in the context of High Energy Physics analyses. The examples presented use the Toolkit for Multivariate Analysis (TMVA) based on ROOT and describe our improvements to the SVM functionality and new tools introduced for cross validation within this framework.

Il romanzo Loufoque di éric chevillard: usare la lingua per leccarsi le dita dei baffi
Creators: name: Finardi, Gianmaria
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: "The subject of this work is an analysis of the novels by Éric Chevillard published between 1987 and 2012 by Minuit. Chevillard, one of the most unique voices in the current panorama of French literature, is considered heir to authors like Beckett and Michaux by critics who incessantly search for a collocation for his “unnerving” texts. He progressively elaborates an incongrous aesthetics, aimed at involving the reader in the construction of a deep-seated sense that continuously eludes every attempt to categorize it, hovering between playfulness, linguistic inventiveness and the exposure of plausible fictions. This contribution aims at accepting the challenge offered by the novels themselves, offering a label which expresses both their nuances and elusiveness, able to communicate the infinite facades of their ambiguous poetics through incongruity: the loufoque. This aesthetic category can also be related to principles of linguistic economy, in order to strengthen the analysis with a further purpose. On the one hand, the semiotic acceptation of loufoque enables to see the unexpected rigour of the texts, whose propensity to poke fun at the reader represents one of the most serious aims, whose almost nonsensical effects presume a logical criteria for writing. On the other hand, the reference to the loufoque itself allows to underline the intertextual dimension of such intriguing fictions and collocates them in the steps of a specific literary tradition."

description: We construct a family of infinite simple groups that we call \emph{twisted Brin-Thompson groups}, generalizing Brin's higher-dimensional Thompson groups $sV$ ($s\in\mathbb{N}$). We use twisted Brin-Thompson groups to prove a variety of results regarding simple groups. For example, we prove that every finitely generated group embeds quasi-isometrically as a subgroup of a two-generated simple group, strengthening a result of Bridson. We also produce examples of simple groups that contain every $sV$ and hence every right-angled Artin group, including examples of type $\textrm{F}_\infty$ and a family of examples of type $\textrm{F}_{n-1}$ but not of type $\textrm{F}_n$, for arbitrary $n\in\mathbb{N}$. This provides the second known infinite family of simple groups distinguished by their finiteness properties.

Exploiting the memory effect in MCFs the images in our system are directly obtained without any post-processing using a static wavefront correction obtained from a single calibration procedure. Our approach allows for video-rate 3D widefield imaging of incoherently illuminated objects with imaging speed not limited by the wavefront shaping device refresh rate.

description: Iron oxide is a key compound to understand the state of the deep Earth. It has been believed that previously known oxides such as FeO and Fe2O3 will be dominant at the mantle conditions. However, recent observation of FeO2 shed another light to the composition of the deep lower mantle (DLM) and thus understanding of the physical properties of FeO2 will be critical to model DLM. Here, we report the electronic structure and structural properties of FeO2 by using density functional theory (DFT) and dynamic mean field theory (DMFT). The crystal structure of FeO2 is composed of Fe2+ and O2 2- dimers, where the Fe ions are surround by the octahedral O atoms. We found that the bond length of O2 dimer, which is very sensitive to the change of the Coulomb interaction U of Fe 3d orbital, plays an important role in determining the electronic structures. The band structures of DFT+DMFT show that the metal-insulator transition is driven by the change of U and pressure. We suggest that the correlation effect should be considered to correctly describe the physical properties of FeO2 compound.

description: We extend Lawrence's representations of the braid groups to relative homology modules, and we show that they are free modules over a Laurent polynomials ring. We define homological operators and we show that they actually provide a representation for an integral version for $U_q \mathfrak{sl}(2)$. We suggest an isomorphism between a given basis of homological modules and the standard basis of tensor products of Verma modules, and we show it to preserve the integral ring of coefficients, the action of $U_q \mathfrak{sl}(2)$, the braid group representations and their grading. This recovers an integral version for Kohno's theorem relating absolute Lawrence representations with quantum braid representation on highest weight vectors. It is an extension of the latter theorem as we get rid of generic conditions on parameters, and as we recover the entire product of Verma-modules as a braid group and a $U_q \mathfrak{sl}(2)$-module.

description: The nature of warm, ionized gas outside of galaxies may illuminate several key galaxy evolutionary processes. A serendipitous observation by the MaNGA survey has revealed a large, asymmetric H$α$ complex with no optical counterpart that extends $\approx8"$ ($\approx6.3$ kpc) beyond the effective radius of a dusty, starbursting galaxy. This H$α$ extension is approximately three times the effective radius of the host galaxy and displays a tail-like morphology. We analyze its gas-phase metallicities, gaseous kinematics, and emission-line ratios, and discuss whether this H$α$ extension could be diffuse ionized gas, a gas accretion event, or something else. We find that this warm, ionized gas structure is most consistent with gas accretion through recycled wind material, which could be an important process that regulates the low-mass end of the galaxy stellar mass function.

Laurence Sterne’s Tristram Shandy and a Tradition of Dissent
Creators: name: Murphy, Neil
Publisher: name: EUT Edizioni Università di Trieste
Year: 2013

description: Samuel Johnson’s famous dismissal of Sterne’s Tristram Shandy (“Nothing odd will do long. Tristram Shandy did not last.”) might well be one of the most short-sighted critical claims in literary history. In recent years, Sterne’s novel has been successfully adapted as a film and as a graphic novel and has been repeatedly cited as a major influence on Modernism and Postmodernism, a forerunner to the major metafictional texts of the twentieth century, and Calvino’s claim that Tristram Shandy is the “undoubted progenitor of all avant-garde novels of our century,” offers an indication of the value in which it is held among many experimental fiction writers. This paper will present a case that it is precisely Tristram Shandy’s ‘oddness’ that has ensured its place in an alternative novelistic tradition in Europe, a tradition that finds ample correspondence with the non-realist tradition in the history of the Irish novel, a tradition that has formal and philosophical dissonance at its centre.

Counting hyperbolic multi-geodesics with respect to the lengths of individual components

Subjects: subject: Dynamical Systems (math.DS)

description: Given a connected, oriented, complete, finite area hyperbolic surface $X$ of genus $g$ with $n$ punctures, Mirzakhani showed that the number of multi-geodesics on $X$ of total hyperbolic length $\leq L$ in the mapping class group orbit of a given simple or filling closed multi-curve is asymptotic as $L \to \infty$ to a polynomial in $L$ of degree $6g-6+2n$. We establish asymptotics of the same kind for countings of multi-geodesics in mapping class group orbits of simple or filling closed multi-curves that keep track of the hyperbolic lengths of individual components, proving and generalizing a conjecture of Wolpert. In the simple case we consider more precise countings that also keep track of the class of the multi-geodesics in the space of projective measured geodesic laminations. We provide a unified geometric and topological description of the leading terms of the asymptotics of all the countings considered. Our proofs combine techniques and results from several papers of Mirzakhani as well as ideas introduced by Margulis in his thesis.

description: A study about the energy and momentum distributions of a new charged regular black hole solution with a nonlinear electrodynamics source is presented. The energy and momentum are calculated using the Einstein and Møller energy-momentum complexes. The results show that in both pseudotensorial prescriptions the expressions for the energy of the gravitational background depend on the mass $M$ and the charge $q$ of the black hole, an additional factor $β$ coming from the spacetime metric considered, and the radial coordinate $r$, while in both prescriptions all the momenta vanish. Further, it is pointed out that in some limiting and particular cases the two complexes yield the same expression for the energy distribution as that obtained in the relevant literature for the Schwarzschild black hole solution.

Determinants of Profitability in Domestic Banking Markets: - Implications of Foreign Bank Entry.
Creators: name: Sabir, Nasir
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: A policy of openness of the domestic banking markets to international bank participation is not a universally accepted argument. While arguments in favor of foreign bank entry are argued to be broad based, there exist a set of concerns with regard to the potentially adverse effects of opening to international involvement. But neither side of these arguments is supported by hard evidence. This paper in the first place attempts to investigate what the determinants of profitability in domestic banking markets are. Afterwards, the implications of foreign bank entry to the profitability of the domestic sector will be analyzed based on the lessons taught from the experiences of the selected East African countries. In order to attempt its objectives the paper employs a dynamic econometric model, which captures the extent of barriers to entry on the profitability of the local sector through the coefficient of the lagged dependent variable (lagged profit). The problem of inconsistency and bias of OLS estimators is handled by application of the Arellano and Bover(1995) GMM estimation method. This method exploits the orthogonality condition that exists between lagged levels and differences in the difference equation and that of instruments of lagged differences and the levels in the original equation. Accordingly, it is found that bank specific variables like equity to total assets, customer and short term funding to total assets, and productivity are highly significant determinants of profitability while the credit risk to total loans and overheads to total assets, though not that significant, they do have an inverse relationship with bank profitability. Furthermore, both the industry specific variables and the macro economic variables are found to be significant determinants. The coefficient of the lagged dependent variable also indicates that the Ethiopian Commercial banking market is not characterized by competitive conditions and profits show a tendency to persist from one year to the other. This implies that, entry of foreign banks will reduce the profitability of the local Commercial banks as international banks exploit their competitive advantages and as they internalize the economic benefit of the knowledge they created, possibly subjecting domestic banks to operate at a reduced rate of return where the issue of their survival may be put in to question. Conclusively, since most of these determinants are highly affected by the quality of management either through its direct or indirect influence, it can be suggested that optimal policies to bank management is the right direction to follow in order to spur progress.

description: We present a rest-frame composite spectrum for Seyfert 1 galaxies using spectra obtained from the DR12 release of the Sloan Digital Sky Survey (SDSS). The spectrum is constructed by combining data from a total of 10,112 galaxies, spanning a redshift range of 0 to 0.793. We produce an electronic table of the median and geometric mean composite Seyfert 1 spectrum. We measure the spectral index of the composite spectrum, and compare it with that of the composite quasar spectrum. We also measure the flux and width of the strong emission lines present in the composite spectrum. We compare the entire spectrum with the quasar spectrum in the context of the AGN unification model. The two composite spectra match extremely well in the blue part of the spectrum, while there is an offset in flux in the red portion of the spectrum.

When $g\leq1$ and the characteristic of the ground field is zero, it is classical that the normal bundle is strictly semistable. We show that this fails in characteristic $2$ for all rational curves of even degree.

description: En 2011, un poisson-globe a été observé pour la première fois près de l’archipel de Ryukyu au large du Japon. Ce poisson construit un nid circulaire en sable afin de réaliser sa parade nuptiale et pour protéger ses œufs. Celui-ci est d’environ 2m de diamètre et il possède deux parties, centrale et périphérique. La partie périphérie possède un motif constitué d’une dune et deux vallées, répété entre 24 et 32 fois autour de la structure. Dans le cadre de la reproduction, les œufs sont déposés par la femelle dans la partie centrale du nid afin de les protéger jusqu’à l’éclosion. L’objectif de ce Mémoire d’Initiation à la Recherche en partenariat avec Dassault Systèmes est de mettre en évidence un ralentissement du courant marin par la structure du nid, de manière qualitative et quantitative. Pour cela, des simulations fluides sont utilisées afin de modéliser un écoulement sur un modèle 3D de la structure du nid. Des premiers résultats visuels ont montré ce ralentissement du courant au sein de la structure du nid. En effet, les vitesses au centre du nid et à la sortie du nid sont quasiment nulles. Une étude statistique des valeurs de vitesses selon des zones prédéfinies au sein du nid a montré que la géométrie des dunes ralentit la vitesse de 78% entre l’entrée et le centre du nid. De plus, l’ensemble de la structure ralentit le courant au cours du temps.

Lost in Translation: An Intercultural Examination of Canadian Post-Secondary Marketing  Efforts Towards International Students
Creators: Al Hammouri, Saba
Publisher: name: University of Alberta Library
Year: 2021

Purpose: To understand the level of intercultural literacy exhibited by Canadian post-secondary

institutions in their efforts to communicate and recruit international students through the use of

targeted publications, such as the viewbook. Design: This project uses a case study approach that

examines nine viewbooks from the top five universities in Canada using a heuristic developed

from existing literature surrounding intercultural communication, cultural variations, and

Hofstede's cultural dimensions. Findings: This study found that most of the institutions

examined failed to demonstrate an adequate level of intercultural literacy, as most of their

publications favoured Canadian cultural elements rather than adapting to the international

audiences they wish to recruit. The findings of the study also highlight that there is often little to

no variation between the international and domestic versions of the viewbooks, further

illustrating a lack of effort in adaptation. Originality and Value: This research provides a tool

that can be used by organizations and industries, domestically and globally when trying to

understand how to communicate effectively with individuals from various cultural backgrounds.

description: The problem of estimating non-resonant astrophysical S-factors and thermonuclear reaction rates, based on measured nuclear cross sections, is of major interest for nuclear energy generation, neutrino physics, and element synthesis. Many different methods have been applied in the past to this problem, almost all of them based on traditional statistics. Bayesian methods, on the other hand, are now in widespread use in the physical sciences. In astronomy, for example, Bayesian statistics is applied to the observation of extra-solar planets, gravitational waves, and type Ia supernovae. However, nuclear physics, in particular, has been slow to adopt Bayesian methods. We present astrophysical S-factors and reaction rates based on Bayesian statistics. We develop a framework that incorporates robust parameter estimation, systematic effects, and non-Gaussian uncertainties in a consistent manner. The method is applied to the d(p,$γ$)$^3$He, $^3$He($^3$He,2p)$^4$He, and $^3$He($α$,$γ$)$^7$Be reactions, important for deuterium burning, solar neutrinos, and big bang nucleosynthesis.

description: The magnetization $|Ω_{\mathrm e}|/ω_{\mathrm{e}}$ is an important parameter in plasma astrophysics, where $Ω_{\mathrm e}$ and $ω_{\mathrm{e}}$ are the electron gyro-frequency and electron plasma frequency, respectively. It only depends on the mass ratio $m_{\mathrm i}/m_{\mathrm e}$ and the light-to-Alfvén speed ratio $c/v_{\mathrm{Ai}}$, where $m_{\mathrm i}$ ($m_{\mathrm e}$) is the ion (electron) mass, $c$ is the speed of light, and $v_{\mathrm{Ai}}$ is the ion Alfvén speed. Nonlinear numerical plasma models such as particle-in-cell simulations must often assume unrealistic values for $m_{\mathrm i}/m_{\mathrm e}$ and for $c/v_{\mathrm{Ai}}$. Because linear theory yields exact results for parametric scalings of wave properties at small amplitudes, we use linear theory to investigate the dispersion relations of Alfvén/ion-cyclotron and fast-magnetosonic/whistler waves as prime examples for collective plasma behaviour depending on $m_{\mathrm i}/m_{\mathrm e}$ and $c/v_{\mathrm{Ai}}$. We analyse their dependence on $m_{\mathrm i}/m_{\mathrm e}$ and $c/v_{\mathrm{Ai}}$ in quasi-parallel and quasi-perpendicular directions of propagation with respect to the background magnetic field for a plasma with $β_j\sim1$, where $β_j$ is the ratio of the thermal to magnetic pressure for species $j$. Although their dispersion relations are largely independent of $c/v_{\mathrm{Ai}}$ for $c/v_{\mathrm{Ai}}\gtrsim 10$, the mass ratio $m_{\mathrm i}/m_{\mathrm e}$ has a strong effect at scales smaller than the ion inertial length. Moreover, we study the impact of relativistic electron effects on the dispersion relations. Based on our results, we recommend aiming for a more realistic value of $m_{\mathrm i}/m_{\mathrm e}$ than for a more realistic value of $c/v_{\mathrm{Ai}}$ in non-relativistic plasma simulations if such a choice is necessary, although $\dots$

description: We investigate at the subscale of the neighborhoods of a highly populated city the incidence of property crimes in terms of both the resident and the floating population. Our results show that a relevant allometric relation could only be observed between property crimes and floating population. More precisely, the evidence of a superlinear behavior indicates that a disproportional number of property crimes occurs in regions where an increased flow of people takes place in the city. For comparison, we also found that the number of crimes of peace disturbance only correlates well, and in a superlinear fashion too, with the resident population. Our study raises the interesting possibility that the superlinearity observed in previous studies [Bettencourt et al., Proc. Natl. Acad. Sci. USA 104, 7301 (2007) and Melo et al., Sci. Rep. 4, 6239 (2014)] for homicides versus population at the city scale could have its origin in the fact that the floating population, and not the resident one, should be taken as the relevant variable determining the intrinsic microdynamical behavior of the system.

description: Metallic glasses have attracted considerable interest in recent years due to their unique combination of superb properties and processability. Predicting bulk metallic glass formers from known parameters remains a challenge and the search for new systems is still performed by trial and error. It has been speculated that some sort of "confusion" during crystallization of the crystalline phases competing with glass formation could play a key role. Here, we propose a heuristic descriptor quantifying confusion and demonstrate its validity by detailed experiments on two well-known glass forming alloy systems. With the insight provided by these results, we develop a robust model for predicting glass formation ability based on the spectral decomposition of geometrical and energetic features of crystalline phases calculated ab-initio in the AFLOW high throughput framework. Our findings indicate that the formation of metallic glass phases could be a much more common phenomenon than currently estimated, with more than 17% of binary alloy systems being potential glass formers. Our approach is capable of pinpointing favorable compositions, overcoming a major bottleneck hindering the discovery of new materials. Hence, it is demonstrated that smart descriptors, based solely on the energetics and structure of competing crystalline phases calculated from first-principles and available in online databases, others the sought-after key for accelerated discovery of novel metallic glasses.

description: Up-conversion single photon detector (UCSPD) has been widely used in many research fields including quantum key distribution (QKD), lidar, optical time domain reflectrometry (OTDR) and deep space communication. For the first time in laboratory, we have developed an integrated four-channel all-fiber UCSPD which can work in both free-running and gate modes. This compact module can satisfy different experimental demands with adjustable detection efficiency and dark count. We have characterized the key parameters of the UCSPD system.

description: In many systems motion occurs on deformed and deformable surfaces, setting up the possibility for dynamical interactions solely mediated by the coupling of the entities with their environment. Here we study the "two-body" dynamics of robot locomotion on a highly deformable spandex membrane in two scenarios: one in which a robot orbits a large central depression and the other where the two robots affect each other's motion solely through mutual environmental deformations. Inspired by the resemblance of the orbits of the single robot with those of general relativistic orbits around black holes, we recast the vehicle plus membrane dynamics in physical space into the geodesic motion of a "test particle" in a fiducial curved space-time and demonstrate how this framework facilitates understanding the observed dynamics. The two-robot problem also exhibits a resemblance with Einstein's general relativistic view of gravity, which in the words of Wheeler: "spacetime tells matter how to move; matter tells spacetime how to curve." We generalize this case the mapping to include a reciprocal coupling that translates into robotic curvature-based control schemes which modify interaction (promoting avoidance or aggregation) without long-range sensing. Our work provides a starting point for developing a mechanical analog gravity system as well as develops a framework that can provide insights into active matter in deformable environments and robot exploration in complex landscapes.

Abstract: The gilthead sea bream (Sparus aurata) is a marine fish of great importance for Mediterranean aquaculture. This species has long been considered resistant to Nervous Necrosis Virus (NNV), an RNA virus that causes massive mortalities in several farmed fish animals. However, the recent appearance of RGNNV/SJNNV reassortant strains started to pose a serious threat to sea bream hatcheries, as it is able to infect larvae and juveniles of this species. While host response to NNV has been extensively studied in adult fish, little attention has been devoted to early life history stages, which are generally the most sensitive ones. Here we report for the first time a time-course RNA-seq analysis on 21-day old fish gilthead sea bream larvae experimentally infected with a RGNNV/SJNNV strain. NNV-infected and mock-infected samples were collected at four time points (6 h, 12 h, 24 h, and 48 h post infection). Four biological replicates, each consisting of five pooled larvae, were analysed for each time point and group. A large set of genes were found to be significantly regulated, especially at early time points (6 h and 12 h), with several heat shock protein encoding transcripts being up-regulated (e.g. hspa5, dnaj4, hspa9, hsc70), while many immune genes were down-regulated (e.g. myd88 and irf5 at T06, pik3r1, stat3, jak1, il12b and il6st at T12). A gene set enrichment analysis (GSEA) identified several altered pathways/processes. For instance, the formation of peroxisomes, which are important anti-viral components as well as essential for nervous system homeostasis, and the autophagy pathway were down-regulated at 6 h and 24 h post infection (hpi). Finally, two custom “reactomes” (i.e. significant gene sets observed in other studies) were defined and used. The first reactome integrated the transcriptomic response to NNV in different fish species, while the second one included all genes found to be stimulated either by interferon (IFN) or by IFN and Chikungunya virus in zebrafish. Genes in both reactomes showed predominant up-regulation at 6hpi and 12hpi and a general down-regulation at 24hpi. Such evidence suggest a certain degree of similarity between the response of sea bream and that of other fish species to NNV, while the observed down-regulation of IFN- and viral-stimulated pathways argues for a possible interference of NNV against the host response.

Den psychischen Versehrungen von Kriegsteilnehmern verschiedener Länder im Zeitalter der Weltkriege widmen sich die sechs Beiträge des Themenschwerpunktes, die in loser Folge in den kommenden Wochen veröffentlicht werden. Sie gewähren Einblick in die neueste, breit gefächerte Forschung zum Thema und zeigen, dass das Erscheinungsbild, die Diagnose und die Anerkennung psychischer Kriegsleiden keineswegs auf universellen Standards beruhten, sondern zutiefst historisch waren – nämlich das Ergebnis eines nach Zeit und Ort unterschiedlich verlaufenden, konflikthaften Aushandlungsprozesses, der sich bis in unsere Gegenwart fortsetzt.

description: We investigate the proof complexity of extended Frege (EF) systems for basic transitive modal logics (K4, S4, GL, ...) augmented with the bounded branching axioms $\mathbf{BB}_k$. First, we study feasibility of the disjunction property and more general extension rules in EF systems for these logics: we show that the corresponding decision problems reduce to total coNP search problems (or equivalently, disjoint NP pairs, in the binary case); more precisely, the decision problem for extension rules is equivalent to a certain special case of interpolation for the classical EF system. Next, we use this characterization to prove superpolynomial (or even exponential, with stronger hypotheses) separations between EF and substitution Frege (SF) systems for all transitive logics contained in $\mathbf{S4.2GrzBB_2}$ or $\mathbf{GL.2BB_2}$ under some assumptions weaker than $\mathrm{PSPACE \ne NP}$. We also prove analogous results for superintuitionistic logics: we characterize the decision complexity of multi-conclusion Visser's rules in EF systems for Gabbay--de Jongh logics $\mathbf T_k$, and we show conditional separations between EF and SF for all intermediate logics contained in $\mathbf{T_2 + KC}$.

description: Measuring the rate at which the long-lived, neutral kaon decays into a neutral pion, neutrino, and anti-neutrino allows physicists an opportunity to test precise predictions made by the Standard Model. Differences between theoretical predictions and experimental measurements may point to new physics. Not only does the Standard Model predict a very low probability at approximately 3 $K_L \to π^0 ν\barν$ decays in 100 billion $K_L$ decays, but many of the common decays leave false signals in the detector that look the same as the true signal. Charged decays have been studied to determine the required detection efficiency necessary to eliminate them. The conclusion of these studies is that a reduction by a factor of $1/(3\times10^9)$ will be required to achieve the 10:1 signal to charged background ratio necessary for the experiment.
