Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Influence of repeated pyrethroid applications on the sensitivity of pyrethroid-resistant pollen beetles (Meligethes aeneus F.) and their offspring

open access: yesJournal für Kulturpflanzen, 2014
In the past, control of pollen beetles was mainly based on the application of synthetic pyrethroids. The frequent and indiscriminate use of this insecticide class resulted in a high selection pressure, ensuing in the formation of resistance, which has ...

Finite-size scaling, dynamic fluctuations, and hyperscaling relation in the Kuramoto model [PDF]

open access: yes, 2015
We revisit the Kuramoto model to explore the finite-size scaling (FSS) of the order parameter and its dynamic fluctuations near the onset of the synchronization transition, paying particular attention to effects induced by the randomness of the intrinsic

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Ecology and Population Structure of Two Sympatric Rodents in a Neotropical Forest of Southeastern Brazil

open access: yesLife
Rodents are the most diverse group of mammals, yet the natural history of many species remains poorly understood due to their elusive behavior. In this study, we examined the population structure, home range, space use, and food selection of two ...

Phase Diagram of Spiking Neural Networks [PDF]

open access: yes, 2014
In computer simulations of spiking neural networks, often it is assumed that every two neurons of the network are connected by a probability of 2\%, 20\% of neurons are inhibitory and 80\% are excitatory.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Dynamic acoustic field activated cell separation (DAFACS) [PDF]

open access: yes, 2015
Advances in diagnostics, cell and stem cell technologies drive the development of application-specific tools for cell and particle separation. Acoustic micro-particle separation offers a promising avenue for highthroughput, label-free, high recovery ...
