Collision-Resistance from Multi-Collision-Resistance

open access: yesJournal of Cryptology, 2022
AbstractCollision-resistant hash functions ($$\textsf{CRH}$$ CRH ) are a fundamental and ubiquitous cryptographic primitive. Several recent works have studied a relaxation of $$\textsf{CRH}$$ CRH called t-way multi-collision-resistant hash functions ($$t\text {-}\textsf{MCRH}$$

High-resolution simulations of stellar collisions between equal-mass main-sequence stars in globular clusters [PDF]

open access: yes, 2001
We performed high-resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6 M_sun main sequence stars.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression

open access: yesMolecular Oncology, EarlyView.
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...

Unphysical features in the application of the Boltzmann collision operator in the time dependent modelling of quantum transport

open access: yes, 2016
In this work, the use of the Boltzmann collision operator for dissipative quantum transport is analyzed. Its mathematical role on the description of the time-evolution of the density matrix during a collision can be understood as processes of adding and ...

Galaxy collisions

open access: yesPhysics Reports, 1999
Theories of how galaxies, the fundamental constituents of large-scale structure, form and evolve have undergone a dramatic paradigm shift in the last few decades. Earlier views were of rapid, early collapse and formation of basic structures, followed by slow evolution of the stellar populations and steady buildup of the chemical elements.

The Polytope-Collision Problem [PDF]

open access: yes44th International Colloquium on Automata, Languages, and Programming (ICALP), 2016
The Orbit Problem consists of determining, given a matrix $A\in \mathbb{R}^{d\times d}$ and vectors $x,y\in \mathbb{R}^d$, whether there exists $n\in \mathbb{N}$ such that $A^n=y$. This problem was shown to be decidable in a seminal work of Kannan and Lipton in the 1980s. Subsequently, Kannan and Lipton noted that the Orbit Problem becomes considerably

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

open access: yesMolecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Collisions Between Gravity-Dominated Bodies: 1. Outcome Regimes and Scaling Laws

open access: yes, 2011
Collisions are the core agent of planet formation. In this work, we derive an analytic description of the dynamical outcome for any collision between gravity-dominated bodies.

Corner collision implies border-collision bifurcation [PDF]

open access: yesPhysica D: Nonlinear Phenomena, 2001
Abstract This paper analyses a so-called corner-collision bifurcation in piecewise-smooth systems of ordinary differential equations (ODEs), for which a periodic solution grazes with a corner of the discontinuity set. It is shown under quite general circumstances that this leads to a normal form that is to lowest order a piecewise-linear map.
