Asynchronous shared channel

G De Marco, G Stachowiak - Proceedings of the ACM Symposium on …, 2017 - dl.acm.org
In this work we address the question whether a simple shared channel could be efficiently
utilized, that is, with a constant throughput and linear packet latency. A shared channel (also …

Information-theoretic and algorithmic aspects of parallel and distributed reconstruction from pooled data

O Gebhard, M Hahn-Klimroth, D Kaaser… - Journal of parallel and …, 2023 - Elsevier
In the pooled data problem the goal is to efficiently reconstruct a binary signal from additive
measurements. Given a signal σ∈{0, 1} n, we can query multiple entries at once and get the …

Scalable wake-up of multi-channel single-hop radio networks

BS Chlebus, G De Marco, DR Kowalski - Theoretical Computer Science, 2016 - Elsevier
We consider single-hop radio networks with multiple channels as a model of wireless
networks. There are n stations connected to b radio channels that do not provide collision …

Scalable and efficient non-adaptive deterministic group testing

D Kowalski, D Pajak - Advances in Neural Information …, 2022 - proceedings.neurips.cc
Group Testing (GT) is about learning a (hidden) subset $ K $, of size $ k $, of some large
domain $ N $, of size $ n\gg k $, using a sequence of queries. A result of a query provides …

Improved bounds for noisy group testing with constant tests per item

O Gebhard, O Johnson, P Loick… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
The group testing problem is concerned with identifying a small set of infected individuals in
a large population. At our disposal is a testing procedure that allows us to test several …

Subquadratic non-adaptive threshold group testing

G De Marco, T Jurdziński, M Różański… - … on Fundamentals of …, 2017 - Springer
We consider threshold group testing–a generalization of a well known and thoroughly
examined problem of combinatorial group testing. In the classical setting, the goal is to …

[HTML][HTML] Contention resolution in a non-synchronized multiple access channel

G De Marco, DR Kowalski - Theoretical Computer Science, 2017 - Elsevier
Multiple access channel is a well-known communication model that deploys properties of
many network systems, such as Aloha multi-access systems, local area Ethernet networks …

Distributed reconstruction of noisy pooled data

M Hahn-Klimroth, D Kaaser - 2022 IEEE 42nd International …, 2022 - ieeexplore.ieee.org
In the pooled data problem we are given a set of n agents, each of which holds a hidden
state bit, either 0 or 1. A querying procedure returns for a query set the sum of the states of …

[HTML][HTML] Subquadratic non-adaptive threshold group testing

G De Marco, T Jurdziński, DR Kowalski… - Journal of Computer and …, 2020 - Elsevier
We consider threshold group testing–a generalization of group testing, which asks to identify
a set of positive individuals in a population, by performing tests on pools of elements. Each …

Non-adaptive pooling strategies for detection of rare faulty items

P Zhang, F Krzakala, M Mézard… - 2013 IEEE International …, 2013 - ieeexplore.ieee.org
We study non-adaptive pooling strategies for detection of rare faulty items. Given a binary
sparse N dimensional signal x, how to construct a sparse binary M× N pooling matrix F such …
