Group Mutual Exclusion Based on Priorities
Journal of Computer Science and Technology, 2011 We propose a distributed solution for the group mutual exclusion problem based on priorities, in a network with no share memory whose members only communicate by messages.

Modeling and Analysis of Dekker-Based Mutual Exclusion Algorithms
ComputersMutual exclusion is a fundamental problem in concurrent/parallel/distributed systems. The first pure-software solution to this problem for two processes, which is not based on hardware instructions like test-and-set, was proposed in 1965 by Th.J.

Synchronization Algorithms on Oriented Chains [PDF]
Scientific Annals of Computer Science, 2008 We present a space- and time-optimal self-stabilizing algorithm, SSDS, for a given synchronization problem on asynchronous oriented chains. SSDS is uniform and works under the unfair distributed daemon.

Self-stabilizing K-out-of-L exclusion on tree network [PDF]
, 2008 In this paper, we address the problem of K-out-of-L exclusion, a generalization of the mutual exclusion problem, in which there are $\ell$ units of a shared resource, and any process can request up to $\mathtt k$ units ($1\leq\mathtt k\leq\ell$).

Molecular motor traffic in a half-open tube
, 2005 The traffic of molecular motors which interact through mutual exclusion is studied theoretically for half-open tube-like compartments. These half-open tubes mimic the shapes of axons.

Molecular Oncology, EarlyView.HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Erythroleukemia: Classification
eJHaem, 2023 Acute erythroid leukemia (AEL) is a rare (2%–5%) form of acute myeloid leukemia (AML). Molecular alterations found in AEL resemble those of other AMLs. We report a classification of AELs in three major classes, with different prognosis and some specific ...

Mutual Exclusion Verification of Parameterized Reader-Writer Algorithm: a Case Study [PDF]
, 2006 This paper presents the verification of mutual-exclusion properties of parameterized reader-writer algorithm. A class of diagram called Predicate diagrams [1] is used for representing the abstractions of parameterized systems described by specifications ...

An asynchronous message-passing distributed algorithm for the global critical section problem
, 2018 This paper considers the global $(l,k)$-CS problem which is the problem of controlling the system in such a way that, at least $l$ and at most $k$ processes must be in the CS at a time in the network.

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...
