k-Step Relative Inductive Generalization [PDF]

open access: yes, 2010
We introduce a new form of SAT-based symbolic model checking. One common idea in SAT-based symbolic model checking is to generate new clauses from states that can lead to property violations.

Survival in equilibrium step fluctuations

open access: yes, 2004
We report the results of analytic and numerical investigations of the time scale of survival or non-zero-crossing probability $S(t)$ in equilibrium step fluctuations described by Langevin equations appropriate for attachment/detachment and edge-diffusion

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Analysis and Experimental of HXD1 Electric Locomotive Steps Fracture

open access: yes机车电传动, 2018
The investigation processes and results of the electric locomotive steps fracture were presented. A locomotive suffered from serious vibration problem was chosen for the test and its normal operations were kept during the test. The wheel out-of-roundness

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Soil bacterial diversity mediated by microscale aqueous-phase processes across biomes

open access: yesNature Communications, 2020
Numerous micro- and macro-scale factors influence soil microbial diversity. Here the authors create a model to demonstrate that fine scale soil moisture influences the carrying capacity of microbes, which then scales up to larger biogeographic patterns.

Two-step melting of Na41+

open access: yes, 2010
The heat capacity of the mass selected Na41+ cluster has been measured using a differential nanocalorimetry method. A two-peak structure appears in the heat capacity curve of Na41+, whereas Schmidt and co-workers [ M. Schmidt, J. Donges, Th. Hippler, and

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

More Than One Step to Financial Stability [PDF]

open access: yes
Visiting Scholar Garry Schinasi examines the European proposals for the creation of both a European Systemic Risk Board (ESRB) to oversee macroprudential regulation and a European System of Financial Supervision (ESFS) to strengthen microprudential ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
