Purcell gain equalized zero-mode waveguide.

We refresh the design of zero-mode waveguides (ZMWs) by introducing metamaterials that makes the zeroth order resonant mode existence. Of particular importance, the resulting electromagnetic field exhibits nearly constant distribution but not a trivial solution of Maxwell's equation, showing great advantage to equalize the excitation rate of molecules throughout the waveguides. A closed form expression for the wave impedance is derived which is verified by the finite-difference time-domain simulations.

One-step metallization of weft-knitted fabrics for wearable biaxial strain sensors.

One-step direct patterning of high definition conductive tracks in textiles is realized through laser direct writing in combination with a silver organometallic ink developed in-house. Photoreduction, nano-crystallization, and sintering are accomplished in one pass under the irradiation of a CW green laser light (λ = 532 nm) at moderate intensities (I ≥ 95 mW/mm). By tailoring the surface tension and viscosity of the ink, high-definition conductive tracks are formed in weft-knitted polyester-Spandex composite fabrics, well-following the laser's profile with negligible coffee stain effect.

[Negative association of FGA gene 128C/G polymorphism with cerebral infarction and its effect on plasma fibrinogen in Hunan Hans].

Objective: To investigate the relationship of FGA gene 128C/G polymorphism and cerebral infarction (CI) and evaluate the effect of FGA-128C/G polymorphism on plasma fibrinogen in Hunan Hans.

Methods: FGA-128C/G polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing in 194 CI patients and 114 healthy controls.

Results: There were CG and CC genotypes in the FGA-128C/G locus.
