Discrete Mathematics, 1988 The paper considers the number SORT(n,r) of parallel processors necessary to sort n elements in time r, in the case where \(r=r(n)\) is small compared to n. The author establishes an asymptotic upper bound \[ f(n,r):=2^{r+1} n^{1+1/r} (\log n)^{2-2/r} (\log \log n)^{-(r- 1)/r} \] for \(2\leq r(n)\leq \log \log \log n\). (Results by Ajtai et a. imply an

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Edge Computing Oriented Certificateless Sorting Ciphertext Retrieval Scheme
Taiyuan Ligong Daxue xuebao[Purposes] In order to ensure the privacy and retrievability of cloud data, ciphertext retrieval technology has emerged. However, cloud computing is no longer able to meet the current data processing requirements.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Gender Differences in Sorting [PDF]
Industrial Relations: A Journal of Economy and Society, 2018 In this paper, we investigate gender differences in workers’ career development within and outside the firm to explain the existence of gender wage gaps. Using Danish employer–employee matched data, we find that good female workers are more likely to move to better firms than men but are less likely to be promoted.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

On-The-Job Search and Sorting [PDF]
SSRN Electronic Journal, 2005 We characterize the equilibrium of a search model with a continuum of job and worker types, wage bargaining, free entry of vacancies and on-the-job search. The decentralized economy with monopsonistic wage setting yields too many vacancies and hence too low unemployment compared to first best. This is due to a business-stealing externality.

FEBS Letters, EarlyView.B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Evolutionary interplay between viruses and R‐loops
FEBS 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.
