description: In the present paper, we study an inhomogeneous pseudo-parabolic equation with nonlocal nonlinearity $$u_t-kΔu_t-Δu=I^γ_{0+}(|u|^{p})+ω(x),\,\ (t,x)\in(0,\infty)\times\mathbb{R}^N,$$ where $p>1,\,k\geq 0$, $ω(x)\neq0$ and $I^γ_{0+}$ is the left Riemann-Liouville fractional integral of order $γ\in(0,1).$ Based on the test function method, we have proved the blow-up result for the critical case $γ=0,\,p=p_c$ for $N\geq3$, which answers an {\bf open question} posed in \cite{Zhou}, and in particular when $k=0$ it improves the result obtained in \cite{Bandle}. An interesting fact is that in the case $γ>0$, the problem does not admit global solutions for any $p>1$ and $\int_{\mathbb{R}^N}ω(x) dx>0.$

Using a Lindbladian approach to model decoherence in two coupled nuclear spins via correlated phase-damping and amplitude damping noise channels

description: In this work, we studied the relaxation dynamics of coherences of different order present in a system of two coupled nuclear spins. We used a previously designed model for intrinsic noise present in such systems which considers the Lindblad master equation for Markovian relaxation. We experimentally created zero-, single- and double- quantum coherences in several two-spin systems and performed a complete state tomography and computed state fidelity. We experimentally measured the decay of zero- and double- quantum coherences in these systems. The experimental data fitted well to a model that considers the main noise channels to be a correlated phase damping channel acting simultaneously on both spins in conjunction with a generalized amplitude damping channel acting independently on both spins. The differential relaxation of multiple-quantum coherences can be ascribed to the action of a correlated phase damping channel acting simultaneously on both the spins.

Noise-tuned bursting in a Hedgehog burster
Creators: name: Zhu, Jinjie
name: Nakao, Hiroya
Publisher: name: arXiv
Year: 2022
Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)
subject: FOS: Physical sciences

description: Noise can shape the firing behaviors of neurons. Here, we show that noise acting on the fast variable of the Hedgehog burster can tune the spike counts of bursts via the self-induced stochastic resonance (SISR) phenomenon. Using the distance matching condition, the critical transition positions on the slow manifolds can be predicted and the stochastic periodic orbits for various noise strengths are obtained. The critical transition positions on the slow manifold with non-monotonic potential differences exhibit a staircase-like dependence on the noise strength, which is also revealed by the stepwise change in the period of the stochastic periodic orbit. The noise-tuned bursting is more coherent within each step while displaying mixed-mode oscillations near the boundaries between the steps. When noise is large enough, noise-induced trapping of the slow variable can be observed, where the number of coexisting traps increases with the noise strength. It is argued that the robustness of SISR underlies the generality of the results discovered in this paper.

description: Flooding is the most destructive natural hazard in the Baltic Sea Basin in general and in Poland in particular. The notion includes floods from rivers and mountain torrents, as well as floods from sea surges in coastal areas, and floods from sewage systems. There have been several large floods in Poland in the last century and in recent decades, with damage exceeding 1% of the Polish GDP. The spatial and temporal characteristics of the flood risk in Poland are reviewed and observations and projections of changes in the flood hazard in the country are discussed. Furthermore, flood defences and flood preparedness systems in Poland are examined, with particular reference to the European Union (EU) Floods Directive, which is being implemented in Poland, an EU country. Finally, the public debate on flood risk and flood preparedness is reviewed.

description: Learning or identifying dynamics from a sequence of high-dimensional observations is a difficult challenge in many domains, including reinforcement learning and control. The problem has recently been studied from a generative perspective through latent dynamics: high-dimensional observations are embedded into a lower-dimensional space in which the dynamics can be learned. Despite some successes, latent dynamics models have not yet been applied to real-world robotic systems where learned representations must be robust to a variety of perceptual confounds and noise sources not seen during training. In this paper, we present a method to jointly learn a latent state representation and the associated dynamics that is amenable for long-term planning and closed-loop control under perceptually difficult conditions. As our main contribution, we describe how our representation is able to capture a notion of heteroscedastic or input-specific uncertainty at test time by detecting novel or out-of-distribution (OOD) inputs. We present results from prediction and control experiments on two image-based tasks: a simulated pendulum balancing task and a real-world robotic manipulator reaching task. We demonstrate that our model produces significantly more accurate predictions and exhibits improved control performance, compared to a model that assumes homoscedastic uncertainty only, in the presence of varying degrees of input degradation.

One--Component Plasma of a Million Particles via angular--averaged Ewald potential: A Monte Carlo study

Year: 2022
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: In this work, we derive a correct expression for the one--component plasma (OCP) energy via the angular--averaged Ewald potential (AAEP). Unlike E.~Yakub and C.~Ronchi (J. Low Temp. Phys. 139, 633 (2005)), who had tried to obtain the same energy expression from a two--component plasma model, we used the original Ewald potential for an OCP. A constant in the AAEP was determined using the cluster expansion in the limit of weak coupling. The potential has a simple form suitable for effective numerical simulations. To demonstrate the advantages of the AAEP, we performed a number of Monte--Carlo simulations for an OCP with up to a million particles in a wide range of the coupling parameter. Our computations turned out at least two orders of magnitude more effective than those with a traditional Ewald potential. A unified approach is offered for the determination of the thermodynamic limit in the whole investigated range. Our results are in good agreement with both theoretical data for a weakly coupled OCP and previous numerical simulations. We hope that the AAEP will be useful in path integral Monte Carlo simulations of the uniform electron gas.

description: In this paper, we define and study a variant of multiple zeta values of level 2 (which is called multiple mixed values or multiple $M$-values, MMVs for short), which forms a subspace of the space of alternating multiple zeta values. This variant includes both Hoffman's multiple $t$-values and Kaneko-Tsumura's multiple $T$-values as special cases. We set up the algebra framework for the double shuffle relations (DBSFs) of the MMVs, and exhibits nice properties such as duality, integral shuffle relation, series stuffle relation, etc., similar to ordinary multiple zeta values. Moreover, we study several $T$-variants of Kaneko-Yamamoto type multiple zeta values by establishing some explicit relations between these $T$-variants and Kaneko-Tsumura $ψ$-values. Furthermore, we prove that all Kaneko-Tsumura $ψ$-values can be expressed in terms of Kaneko-Tsumura multiple $T$-values by using multiple associated integrals, and find some duality formulas for Kaneko-Tsumura $ψ$-values. We also discuss the explicit evaluations for a kind of MMVs of depth two and three by using the method of contour integral and residue theorem. Finally, we investigate the dimensions of a few interesting subspaces of MMVs for small weights.

Min-max theory for $G$-invariant minimal hypersurfaces

description: In this paper, we consider a closed Riemannian manifold $M^{n+1}$ with dimension $3\leq n+1\leq 7$, and a compact Lie group $G$ acting as isometries on $M$ with cohomogeneity at least $3$. After adapting the Almgren-Pitts min-max theory to a $G$-equivariant version, we show the existence of a nontrivial closed smooth embedded $G$-invariant minimal hypersurface $Σ\subset M$ provided that the union of non-principal orbits forms a smooth embedded submanifold of $M$ with dimension at most $n-2$. Moreover, we also build upper bounds as well as lower bounds of $(G,p)$-width which are analogs of the classical conclusions derived by Gromov and Guth. An application of our results combined with the work of Marques-Neves shows the existence of infinitely many $G$-invariant minimal hypersurfaces when ${\rm Ric}_M>0$ and orbits satisfy the same assumption above.

description: Modern question answering (QA) systems need to flexibly integrate a number of components specialised to fulfil specific tasks in a QA pipeline. Key QA tasks include Named Entity Recognition and Disambiguation, Relation Extraction, and Query Building. Since a number of different software components exist that implement different strategies for each of these tasks, it is a major challenge to select and combine the most suitable components into a QA system, given the characteristics of a question. We study this optimisation problem and train classifiers, which take features of a question as input and have the goal of optimising the selection of QA components based on those features. We then devise a greedy algorithm to identify the pipelines that include the suitable components and can effectively answer the given question. We implement this model within Frankenstein, a QA framework able to select QA components and compose QA pipelines. We evaluate the effectiveness of the pipelines generated by Frankenstein using the QALD and LC-QuAD benchmarks. These results not only suggest that Frankenstein precisely solves the QA optimisation problem but also enables the automatic composition of optimised QA pipelines, which outperform the static Baseline QA pipeline. Thanks to this flexible and fully automated pipeline generation process, new QA components can be easily included in Frankenstein, thus improving the performance of the generated pipelines.

Victim-Perpetrator Dichotomy in Transitional Justice: The Case of Post-Genocide Rwanda

description: Transitional justice processes often lead to the construction of a victim-perpetrator dichotomy, which guides and is further reinforced by the transition. The present paper aims to problematize this dichotomized understanding of peopleâ€™s roles in conflict, by locating it within the recent dominant model of transitional justice and demonstrating how it is the result of an inherently political (and disputed) choice, part of the process of constructing post-conflict narratives and dominant discourses on violence and victimhood. Settling for a single conflict story and defining a rigid victim-perpetrator dichotomy can be profoundly excluding and limited in capturing the diversity of victimhood and perpetration experiences, memories and perceptions; and can also (re)produce former and new unequal relations of power. The paper will illustrate this discussion through the case study of post-genocide Rwanda, where a dominant discourse on the 1994 violence has been established, based on a Tutsi victim-Hutu perpetrator dichotomy. The latter not only obscures the plurality of violence and victimization experiences within these groups, but also renders invisible the role of the Twa community. This case aptly illustrates the critique of the often unacknowledged limits and politics of mainstream transitional justice discourse, as well as provides grounds for a deeper reflection on the implications and consequences of leaving these issues unaddressed for countriesâ€™ long-term prospects for reconciliation, in particular, Rwandaâ€™s.Â

description: In 1922, Harald Bohr and Johannes Mollerup established a remarkable characterization of the Euler gamma function using its log-convexity property. A decade later, Emil Artin investigated this result and used it to derive the basic properties of the gamma function using elementary methods of the calculus. Bohr-Mollerup's theorem was then adopted by Nicolas Bourbaki as the starting point for his exposition of the gamma function. This open access book develops a far-reaching generalization of Bohr-Mollerup's theorem to higher order convex functions, along lines initiated by Wolfgang Krull, Roger Webster, and some others but going considerably further than past work. In particular, this generalization shows using elementary techniques that a very rich spectrum of functions satisfy analogues of several classical properties of the gamma function, including Bohr-Mollerup's theorem itself, Euler's reflection formula, Gauss' multiplication theorem, Stirling's formula, and Weierstrass' canonical factorization. The scope of the theory developed in this work is illustrated through various examples, ranging from the gamma function itself and its variants and generalizations (q-gamma, polygamma, multiple gamma functions) to important special functions such as the Hurwitz zeta function and the generalized Stieltjes constants. This volume is also an opportunity to honor the 100th anniversary of Bohr-Mollerup's theorem and to spark the interest of a large number of researchers in this beautiful theory.

Interfacial Electrochemistry of Carbon-Based Materials for Electrocatalysis

description: The so-called “electrification” of our energy systems is being widely explored as a way to help roll back global greenhouse gas emissions and remediate atmospheric CO2 levels. For example, electrification can be paired with already existing renewable energy sources, e.g., wind, solar or hydroelectric, and used to electrochemically drive processes important to energy storage, conversion, and fuel or chemical production. Past the basic integration of electrochemistry, electrochemical catalysis can be employed to drastically improve the efficiency and selectivity of these electrochemical processes. My research focuses on the development of carbon-based electrocatalysts and fundamental investigations of their electrocatalytic mechanisms for reactions relevant to energy storage and conversion. Through a combination of theoretical analysis and experimental investigation, it elucidates the intricate interplay between molecular model systems and real-world electrocatalysts. Exploring the hydrogen evolution reaction (HER) activity of molecular Rh-based electrocatalysts and analogous Rh-coordinated graphene nanoribbon films (RhGNR-2DNS) revealed the diverging behaviors of homogeneous and heterogeneous systems. While molecular species lost HER activity in basic aqueous conditions, RhGNR-2DNS maintained its activity over the full aqueous pH window. The proximity of RhGNR-2DNS to the electrode surface and the local electric fields experienced as a result are implicated in the broader HER activity, thus demonstrating the usefulness of our immobilization approach.
In another study, a new class of triarylmethyl-based carbocations was reported as discharge redox mediators (ORR electrocatalysts) for the Li-O2 battery. The redox mediators were identified to operate through an outer-sphere mechanism and their performance in full Li-O2 cells showed remarkable (up to 36-fold) enhancements to battery discharge capacities. It was further demonstrated how the redox mediation process can control Li-O2 cell potentials and suppress parasitic, surface-mediated ORR.

Victimizing Offenders and Criminalizing Victimhood: Narratives of Mass Incarceration  in a â€œPost-Racialâ€ Era

description: Much conflict resolution literature largely views crime in domestic, American, â€œconflict freeâ€ communities as a problem somewhat outside its scope of intervention or analysis. Scholars often fail to question normative assumptions about criminality and victimhood, and their work reflects narratives of the â€œcriminalâ€ as an independent actor and the â€œcrimeâ€ as an act of unidirectional harm. To address crime, the United States has chosen mass incarceration, out of many possible approaches, which has severe implications for the social and self-perception of both victims and offenders. In this paper we argue that much conflict literature on crime and mass incarceration fails to identify these lasting perceptions and their effect on policy and law. Using narrative analysis, we show that mass incarceration is a product of a protracted latent conflict, clearly sustained by structural and cultural violence, and held in place by generations of public narratives. Our argument illustrates how mass incarceration falls outside common conceptualizations of conflict, often victimizing criminals, criminalizing victimhood, and complicating the victim/offender dichotomy. We use Virginiaâ€™s parole reinstatement review process, initiated by Virginia Governor Terry McAuliffe in June 2014, as the site of our analysis. Our methods are applicable on a larger scale across the United States, and the implications of our findings are nationally relevant. â€œCrime,â€ as usually figured in the U.S., is reliant on victimhood, just as it is reliant on an identifiable offender. Rethinking crime as a product of conflict allows for flexible interpretation, with less defined roles for those participating in and affected by criminal events. Rethinking narrative framing of crime illustrates the deep impact narrative-as-intervention can have for conflict resolution practitioners and theorists, as well as the personal experiences and legal outcomes of all participants. Conceptualizing crime in this way and integrating it into conflict analysis frameworks has profound consequences: It offers analysts and practitioners better tools for identifying and responding to the nuances of crime in American environments. It also allows us new perspectives on race and class as the politics of crime and victimhood emerge. Â
