Spectral phase conjugation with cross-phase modulation compensation [PDF]
, 2004 Spectral phase conjugation with short pump pulses in a third-order nonlinear material is analyzed in depth. It is shown that if signal amplification is considered, the conversion efficiency can be significantly higher than previously considered, while ...

N=1 de Sitter Supersymmetry Algebra
, 2005 Recalling the universal covering group of de Sitter, the transformation properties of the spinor fields $\psi(x)$ and ${\bar\psi}(x)$, in the ambient space notation, are presented in this paper.

Why does a metal-superconductor junction have a resistance? [PDF]
, 2000 This is a tutorial article based on a lecture delivered in June 1999 at the NATO Advanced Study Institute in Ankara. The phenomenon of Andreev reflection is introduced as the electronic analogue of optical phase-conjugation.

Expert Review of Vaccines, 2003 Conjugate vaccines in which the capsular polysaccharide of Haemophilus influenzae type b, common serotypes of Streptococcus pneumoniae and group C Neisseria meningitidis are covalently bound to a protein antigen to convert a T-cell-independent immune response into a T-cell-dependent response have proved highly effective in the prevention of invasive ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Rocky Mountain Journal of Mathematics, 2003 The paper under review contains a large generalization of a result due to \textit{J. Brink} [see Pac. J. Math. 42, 289--312 (1972; Zbl 0218.26012)], concerning the problem of best constants in the inequalities \(\left\| f\right\| _{L^{p}}\leq M(n,p,q)\left\| f^{(n)}\right\| _{L^{q}}\) on the interval \([0,1],\) with the boundary conditions \[ f^{(k)}(0)

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Frontiers in Cellular and Infection Microbiology, 2023 IntroductionVirus-like particles (VLPs) are similar in size and shape to their respective viruses, but free of viral genetic material. This makes VLP-based vaccines incapable of causing infection, but still effective in mounting immune responses.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target
FEBS Letters, EarlyView.This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.
