The laser damage resistance of the coatings for high-power laser systems depends greatly on the surface quality of the substrate. In our work, experimental approaches were employed to understand the interface coupling effect of the substrate surface and coatings on the laser resistance of the coatings. A 1064 nm anti-reflection (AR) coating was deposited by an e-beam coater onto fused silica wi...

A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...

Most eukaryotic cells sense and respond to the mechanical properties of their surroundings. This can strongly influence their collective behavior in embryonic development, tissue function, and wound healing. We use a deformable substrate to measure collective behavior in cell motion due to substrate mediated cell-cell interactions. We quantify spatial and temporal correlations in migration velo...

Site-2 proteases (S2Ps) are intramembrane metalloproteases that cleave transmembrane substrates in all domains of life. Many S2Ps, including human S2P and Mycobacterium tuberculosis Rip1, have multiple substrates in vivo, which are often transcriptional regulators. However, S2Ps will also cleave transmembrane sequences of nonsubstrate proteins, suggesting additional specificity determinants. Ma...

Upon illumination of spinach chloroplasts in the presence of [32P]orthophosphate and AMP and absence of substrate ADP, coupling factor-bound [32P]ADP is formed. This bound r3’P]ADP is stable enough to withstand purification of the coupling factor to homogeneity. However, the ability of this specially bound [““PIADP to serve as the ultimate phosphoryl donor to substrate ADP for the synthesis of ...

The coupling of simultaneous switching noise through the substrate presents an important issue to integration of both noisy digital and sensitive analog circuitry in mixedsignal integrated circuits. Noise is generated by digital aggressor circuits, it further propagates through the common substrate, and finally impacts the performance of analog victim circuitry through body effect and capacitiv...

Taurine alpha-ketoglutarate dioxygenase (tauD) is one of the best-studied alpha-ketoglutarate (alphaKG)-dependent nonheme iron oxygenases. As with all oxygenases, a fine balance must be struck between generating a species sufficiently reactive for the required chemistry and controlling that species to prevent undesirable side reactions [Klinman JP (2007) Accts Chem Res 40:325-333]. In the case ...

Copper(I) and copper(II) 1,5-diaza-cis-decalin complexes [(N2)Cu] are effective precatalysts for aerobic oxidative coupling of naphthol substrates. Mechanistic studies, however, reveal that these complexes are not the reactive form of the catalyst under steady-state conditions. Rather, the active catalyst forms in a presteady-state self-processing step that involves oxygenation of the naphthol ...
