Some people are annoyed their city doesn't repair a pedestrian bridge like they promised, and are now Guerilla-Woodcafting their own. For the second time in a month

Illegale Brücke über die Lahn gebaut - schon zum zweiten Mal
Die Sanierung einer maroden Brücke in Biedenkopf geht Unbekannten offenbar nicht schnell genug: Sie haben heimlich einen Holzsteg über die Lahn gezimmert - und das schon zum zweiten Mal. Der Bürgermeister ist vom Ersatzbau wenig begeistert.

A 10-bit S-box generated by Feistel construction from cellular automata
We propose a new 10-bit S-box generated from a Feistel construction. The subpermutations are generated by a 5-cell cellular automaton based on a unique well-chosen rule and bijective affine transformations. In particular, the cellular automaton rule is chosen based on empirical tests of its ability to generate good pseudorandom output on a ring cellular automaton. Similarly, Feistel's network layout is based on empirical data regarding the quality of the output S-box. We perform cryptanalysis o…

Characterizing ion-acoustic shock wave collisions in Martian multicomponent plasma environments
We present theoretical investigation of colliding ion-acoustic (IA) shock waves in Martian multicomponent plasmas consisting of hydrogen ($H^+$), oxygen ($O^+$) and oxygen molecule ($O_2^+$) ions, including background superthermal electrons (modeled by a $κ$-(kappa) distribution function). A set of Burgers' equations is obtained by adopting a modified Poincaré-Lighthill-Kuo (PLK) perturbation method to describe the head-on-collision dynamics of dissipative nonlinear IA wave structures. We hav…

Slicing Correspondences with High Degree Hypersurfaces
We approximately compute the correspondence degree (as defined by Lazarsfeld and Martin) between two unbalanced complete intersections. This is accomplished by showing that the procedure of taking a subvariety of a product $Y \times Y'$ and intersecting it with $X \times Y'$ (for $X$ a sufficiently ample smooth divisor in $Y$) induces a bijection between two sets of varieties. This may be of independent interest.

Cylindric growth diagrams, walks in simplices, and exclusion processes
We establish bijections between three classes of combinatorial objects that have been studied in very different contexts: lattice walks in simplicial regions as introduced by Mortimer--Prellberg, standard cylindric tableaux as introduced by Gessel--Krattenthaler and Postnikov, and sequences of states in the totally asymmetric simple exclusion process. This perspective allows us to translate symmetries from one setting into another, revealing unexpected properties of these objects. Specificall…

Crystal Eye: all sky MeV monitor with high precision real-time localization
Crystal Eye is a space-based all-sky monitor optimized for the autonomous detection and localization of transients in the 10 keV to 30 MeV energy range, a region where extensive observations and monitoring of various astrophysical phenomena are required. By focusing on the operating environment and its impact on the observation process, we optimized the detector design and assessed its scientific potential. We explored the use of novel techniques to achieve the science goals of the experiment. …

Analysis of points outcome in ATP Grand Slam Tennis using big data and machine learning
Tennis is one of the world's biggest and most popular sports. Multiple researchers have, with limited success, modeled the outcome of matches using probability modelling or machine learning approaches. The approach presented here predicts the outcomes of points in tennis matches. This is based on given a probability of winning a point, based on the prior history of matches, the current match, the player rankings and if the points are started with a first or second. The use of historical public …
