What's Safe

What’s Safe is an ongoing response to Toronto’s social distancing measures. It is a dance score documented cinematically in Trinity Bellwoods Park, with movements inspired by Deepa Iyer’s framework (Mapping Our Roles in Social Change Ecosystems, 2020) and Jay Pitter’s open letter to Canadian urbanists (A Call to Courage, 2020). The project was conceived, performed, and captured by the authors of this paper. The two dancers, our second and third authors, engage in creative problem-solving by facing the reality of socially-distant grounds for play and suggesting a different type of productivity, one which is conducive to individual and social growth. The movements are then captured by our multimedia creator (or fourth author), while our artist-researcher (first author) curates and provides critique throughout. The final project considers artistic practice in response to social change as informed by (un)productivity. It uses productive imagination (e.g., play, improvisation, creative problem-solving) to investigate parameters of safety (e.g., surveillance, control, space). Through the dancers’ improvisations, we attempt to navigate these tensions and better position ourselves in relation to our current socio-geographical circumstances.

Inexact Nonconvex Newton-Type Methods

The paper aims to extend the theory and application of nonconvex Newton-type methods, namely trust region and cubic regularization, to the settings in which, in addition to the solution of subproblems, the gradient and the Hessian of the objective function are approximated. Using certain conditions on such approximations, the paper establishes optimal worst-case iteration complexities as the exact counterparts. This paper is part of a broader research program on designing, analyzing, and implementing efficient second-order optimization methods for large-scale machine learning applications. The authors were based at UC Berkeley when the idea of the project was conceived. The first two authors were PhD students, the third author was a postdoc, all supervised by the fourth author.

Romanian-Hungarian cooperation in the field of reduction of seismic risk to infrastructures

<p>Between the Ion Mincu University of Architecture and Urbanism in Bucharest, Romania and the Szechenyi Istvan University in Gyor, Hungary a cooperation agreement was concluded between the first and fourth author regarding disaster management. A first step was taken in January 2020 starting the reciprocical visits by a visit of the third author to the Romanian university. Exchange encompassed participation to master level courses at the Master Urban Design (urban prospective: urban vulnerability and protection of localities against risks, the later taught by the second author, who is also a titular member of the doctoral school) and a lecture at the doctoral school with discussions moderated by the first and third authors. The conclusions were discussed with the master students as well. The innovative in the cooperation is that it regards how urban planners can contribute to disaster management and infrastructures in a field where they can best plan. Master students learn how to design urban projects while doctoral candidates do research in this, and are thereof complementary. Cooperation will continue by various national and bilateral schemes. This contribution shows the conclusions of the discussions.</p>

Flux-limited and classical viscosity solutions for regional control problems

The aim of this paper is to compare two different approaches for regional control problems: the first one is the classical approach, using a standard notion of viscosity solutions, which is developed in a series of works by the three first authors. The second one is more recent and relies on ideas introduced by Monneau and the fourth author for problems set on networks in another series of works, in particular the notion of flux-limited solutions. After describing and even revisiting these two very different points of view in the simplest possible framework, we show how the results of the classical approach can be interpreted in terms of flux-limited solutions. In particular, we give much simpler proofs of three results: the comparison principle in the class of bounded flux-limited solutions of stationary multidimensional Hamilton–Jacobi equations and the identification of the maximal and minimal Ishii’s solutions with flux-limited solutions which were already proved by Monneau and the fourth author, and the identification of the corresponding vanishing viscosity limit, already obtained by Vinh Duc Nguyen and the fourth author.

A new hypogean species of the genus Chaetomargoreicheia Magrini & Bulirsch, 2005 (Carabidae: Scaritinae: Clivinini) from Croatia

Chaetomargoreicheia Magrini & Bulirsch, 2005 is a recently established genus of scaritine ground beetles (Bulirsch & Guéorguiev, 2008) (treated by certain authors as a subgenus of the genus Reicheadella Reitter, 1913) (Magrini & Bulirsch, 2005; Balkenohl, 2017) which currently contains two endogean species inhabiting the Balkan Peninsula: Chaetomargoreicheia zoufali (Reitter, 1913) and C. lakotai (Magrini & Bulirsch, 2005) (Balkenohl, 2003, 2017; Magrini & Bulirsch, 2005; Bulirsch & Guéorguiev, 2008). The aforementioned species are montane and inhabit confined geographic areas (Jeannel, 1957; Magrini & Bulirsch, 2005). C. zoufali was found only in the surroundings of the village of Ravno (collected beneath a deep layer of leaf-litter), Mt. Bjelasnica, near Trebinje, E Herzegovina (Bosnia and Herzegovina), while C. lakotai was found at the entrance of a cave nearby a road (collected under a huge stone), in Mt. Lovćen, near Kotor, S Montenegro (Reitter, 1913; Holdhaus, 1924; Jeannel, 1957; Magrini & Bulirsch, 2005). Chaetomargoreicheia species represent quite rare, stenoendemic taxa, for each of the up-to-now known species only one specimen has been collected by hand so far (Reitter, 1913; Jeannel, 1957; Magrini & Bulirsch, 2005). The fourth author of the current study investigated numerous underground and endogean high-altitude habitats in Dalmatia (Croatia) in the last few years. As a result of the exploration, he has recently collected a small sample of scaritine ground beetles from a cave in S Croatia. After thorough analysis of the sample, we have identified a new Chaetomargoreicheia species.

Resolution of T. Ward's Question and the Israel–Finch Conjecture: Precise Analysis of an Integer Sequence Arising in Dynamics

We analyse the first-order asymptotic growth of \[ a_{n}=\int_{0}^{1}\prod_{j=1}^{n}4\sin^{2}(\pi jx)\, dx. \] The integer an appears as the main term in a weighted average of the number of orbits in a particular quasihyperbolic automorphism of a 2n-torus, which has applications to ergodic and analytic number theory. The combinatorial structure of an is also of interest, as the ‘signed’ number of ways in which 0 can be represented as the sum of ϵjj for −n ≤ j ≤ n (with j ≠ 0), with ϵj ∈ {0, 1}. Our result answers a question of Thomas Ward (no relation to the fourth author) and confirms a conjecture of Robert Israel and Steven Finch.
