Photochemistry and Photobiology, EarlyView.The left panel reports the measured time course data of melatonin concentration in the blood plasma of 17 BL‐Rs and 15 BL‐NRs at baseline, during a two‐hour stay in the dark, during a one‐hour light exposure to blue light, and again in the dark. The right panel shows the magnitude of melatonin concentration after 60 min of exposure to warm white, cool ...

Girth Analysis of Tanner’s (3, 17)-Regular QC-LDPC Codes Based on Euclidean Division Algorithm
IEEE Access, 2019 In this paper, the girth distribution of the Tanner’s (3, 17)-regular quasi-cyclic LDPC (QC-LDPC) codes with code length $17p$ is determined, where $p$ is a prime and $p \equiv 1~(\bmod ~51)$ .

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Slow slip events (SSEs) represent an aseismic transient slip mode that repeats quasi‐periodically, near or partially overlapping with the megathrust earthquake zone. However, the process of stress interaction between SSEs and earthquake zones is not clearly understood.

Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3
Advanced Materials, Volume 38, Issue 57, 13 October 2026.Through precise epitaxial engineering, the cubic and paraelectric KTaO3${\rm KTaO}_3$ is transformed into a robust ferroelectric. By leveraging lattice‐mismatched substrates to apply controlled epitaxial strain, a stable ferroelectric ground‐state is achieved with a transition temperature as high as 475 K, establishing KTaO3${\rm KTaO}_3$ as a highly ...

On the girth of Tanner (3,7) quasi-cyclic LDPC codes [PDF]
Transactions on Combinatorics, 2012 S. Kim, et al, have been analyzed the girth of some algebraically structured quasi-cyclic (QC) low-density parity-check (LDPC) codes, i.e. Tanner (3,5) of length 5p, where p is a prime of the form 15m+1. In this paper, by extension this method to Tanner (

Lower Bounds on the Lifting Degree of QC-LDPC Codes by Difference Matrices
IEEE Access, 2018 In this paper, we define two “difference matrices” which correspond to an exponent matrix. We present necessary and sufficient conditions for these difference matrices to have quasi-cyclic low-density parity-check codes (QC-LDPC) codes with

Energy Technology, Volume 14, Issue 10, October 2026.Pulsed anodic oxidation with a 5s rest period transforms electrodeposited ZIF‐67 into porous Co(OH)2/CoOOH nanosheets more extensively than continuous oxidation. The resulting electrode delivers a high specific capacity of 124.7 mAh g−1 and superior rate capability, offering a simple route to high‐performance supercapacitor materials.
