The Input Power Dynamic Range of a Semiconductor Optical Amplifier and Its Relevance for Access Network Applications

IEEE Photonics Journal, 2011
The input power dynamic range (IPDR) of a semiconductor optical amplifier (SOA) gives the input power range within which an SOA can be operated error free.

Tube Formula, Berezinizans and Dwork Formula [PDF]

, 2012
We consider an example of tubes of hypersurfaces in Euclidean space and generalise the tube formula to supercase. By this we assign to a point of the hypersurface in superspace a rational characteristic function. Does this rational function appear when we calculate the zeta-function of an arithmetic variety?

Dependence in Propositional Logic: Formula-Formula Dependence and Formula Forgetting -- Application to Belief Update and Conservative Extension

, 2018
Dependence is an important concept for many tasks in artificial intelligence. A task can be executed more efficiently by discarding something independent from the task.

Kida's formula and congruences [PDF]

, 2005
We prove a formula (analogous to that of Kida in classical Iwasawa theory and generalizing that of Hachimori-Matsuno for elliptic curves) giving the analytic and algebraic p-adic Iwasawa invariants of a modular eigenform over an abelian p-extension of Q ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Study of Coupling Length of Concentrically Curved Waveguides

IEEE Photonics Journal, 2012
In this paper, we propose a method based on Helmholtz equation to determine the coupling length of the light propagating in concentrically curved waveguides by the conformal transformation.

Analysis of intestinal flora development in breast-fed and formula-fed infants by using molecular identification and detection methods.

Journal of Pediatric Gastroenterology and Nutrition - JPGN, 2000
BACKGROUND An obvious difference between breast-fed and formula-fed newborn infants is the development of the intestinal flora, considered to be of importance for protection against harmful micro-organisms and for the maturation of the intestinal immune ...

Quantitative proteomic analysis reveals different characteristics of bladder cancer cells after exposure to bisphenol A

FEBS Open Bio, EarlyView.
Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Stability Studies on Continuous-Wave Broadband Generated in an Erbium-Doped Fiber Ring Laser Using Highly Nonlinear Fiber

IEEE Photonics Journal, 2010
Continuous-wave (CW) broadband in the C- and L-band wavelength regions is demonstrated by introducing a highly nonlinear fiber (HNLF) in an erbium-doped fiber ring laser (EDFRL).

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment

Aging and Cancer, EarlyView.
Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.
