Hierarchy of quasisymmetries and degeneracies in the CoSi family of chiral crystal materials
Philip Johannes Walter Moll, Yi-Chiang Sun, Chunyu Guo
In materials, certain approximated symmetry operations can exist in a lower-order approximation of the effective model but are good enough to influence the physical responses of the system, and these approximated symmetries were recently dubbed "quasisymme ...
AMER PHYSICAL SOC2023On the Efficiency of Polar-Like Decoding for Symmetric Codes
Rüdiger Urbanke, Kirill Ivanov
The recently introduced polar codes constitute a breakthrough in coding theory due to their capacity-achieving property. This goes hand in hand with a quasilinear construction, encoding, and successive cancellation list decoding procedures based on the Plo ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Symmetry in design and decoding of polar-like codes
The beginning of 21st century provided us with many answers about how to reach the channel capacity. Polarization and spatial coupling are two techniques for achieving the capacity of binary memoryless symmetric channels under low-complexity decoding algor ...
EPFL2022Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability
Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, Alexandre Bagnoud
Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date. Here, we measured the kinetics of MOX in stream sediments of 14 sites to res ...
2020Kaleidoscopic groups: permutation groups constructed from dendrite homeomorphisms
Given a transitive permutation group, a fundamental object for studying its higher transitivity properties is the permutation action of its isotropy subgroup. We reverse this relationship and introduce a universal construction of infinite permutation group ...
POLISH ACAD SCIENCES INST MATHEMATICS-IMPAN2019Renormalization in Quantum Field Theory (after R. Borcherds)
The aim of this manuscript is to provide a complete and precise formula- tion of the renormalization picture for perturbative Quantum Field Theory (pQFT) on general curved spacetimes introduced by R. Borcherds in [10]. More precisely, we give a full proof ...
2019Recommendation Strategy Portfolios
Boi Faltings, Claudiu-Cristian Musat
A recommender system comprising at least one computing device which comprises one or more processors and one or more computer-readable storage media operatively coupled to at least one of the processors, wherein said computing device performs a method of a ...
2015Tracking Individuals Shows Spatial Fidelity Is a Key Regulator of Ant Social Organization
Ants live in organized societies with a marked division of labor among workers, but little is known about how this division of labor is generated. We used a tracking system to continuously monitor individually tagged workers in six colonies of the ant Camp ...
Amer Assoc Advancement Science2013Evolution of dispersal in explicitly spatial metacommunities
We apply an evolutionary game theoretic approach to the evolution of dispersal in explicitly spatial metacommunities, using a flexible parametric class of dispersal kernels, namely 2Dt kernels, and study the resulting evolutionary dynamics and outcomes. We ...
Elsevier2011Towards Group Transport by Swarms of Robots
We examine the ability of a swarm robotic system to transport cooperatively objects of different shapes and sizes. We simulate a group of autonomous mobile robots that can physically connect to each other and to the transported object. Controllers — artifi ...
