HADC: A Hybrid Compression Approach for DNA Sequences

IEEE Access, 2022
In the blossoming age of Next Generation Sequencing (NGS) technologies, genome sequencing has become much easier and more affordable. The large number of enormous genomic sequences obtained demand the availability of huge storage space in order to be ...

Optimal compression of combinatorial state spaces [PDF]

Innovations in Systems and Software Engineering, 2019
Efficiently deciding reachability for model checking problems requires storing the entire state space. We provide an information theoretical lower bound for these storage requirements using only the assumption of locality in the model checking input. The theory shows that a set of n vectors with k slots can be compressed to a single slot plus

Magnetic resonance imaging in the evaluation of different compression locations in patients with cervical spondylotic radiculopathy

Journal of Orthopaedic Surgery and Research
Objective Studies showed that T2-weighted turbo spin-echo SPACE (T2-SPACE) could be superior to conventional two-dimensional magnetic resonance imaging (2D MRI) to detect the locations of nerve root compression.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

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

FEBS 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 ...

Intensity limitations due to space charge for bunch compression in synchrotrons

Physical Review Accelerators and Beams, 2018
Bunch compression achieved via a fast bunch rotation in longitudinal phase space is a well-accepted scheme to generate short, intense ion bunches for various applications.

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

FEBS 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.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Mechanical compression process of gangue filling and settlement analysis of wide strip rock stratum

Meikuang Anquan
Taking 1102 gangue filling face of Tingnan Coal Mine as the research object, theoretical analysis, numerical simulation, laboratory test and field measurement were used to study the process of gangue compression and the law of strata subsidence.
