A Tunable Dispersion Waveguide Based on Graphene–Silicon Lateral Slot Geometric Structure
IEEE Photonics Journal, 2017 The dispersion profiles of a hybrid graphene–silicon (HyGS) slot waveguide with trilayers of graphene are investigated in this paper. By tuning the bias voltage on graphene layer, the zero dispersion wavelengths (ZDW) of HyGS slot waveguide can be

Spatiotemporally mode-locked soliton fiber laser at 2.8 μm
High Power Laser Science and Engineering, 2023 Spatiotemporal mode-locking creates great opportunity for pulse energy scaling and nonlinear optics research in fiber. Until now, spatiotemporal mode-locking has only been realized in normal-dispersion dissipative soliton and similariton fiber lasers. In

Photon lifetime in a cavity containing a slow-light medium
, 2011 We investigate experimentally the lifetime of the photons in a cavity containing a medium exhibiting strong positive dispersion. This intracavity positive dispersion is provided by a metastable helium gas at room temperature in the electromagnetically ...

FEBS Letters, EarlyView.Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Dispersion engineering via nonlocal transformation optics
, 2015 Transformation optics (TO) is one of the most powerful and versatile frameworks for the systematic design of artificial media. Recently (G. Castaldi et al., Phys. Rev. Lett., 108, 063902, 2012), we have proposed an extension of this approach that enables

Disruption of SETD3‐mediated histidine‐73 methylation by the BWCFF‐associated β‐actin G74S mutation
FEBS Letters, EarlyView.The β‐actin G74S mutation causes altered interaction of actin with SETD3, reducing histidine‐73 methylation efficiency and forming two distinct actin variants. The variable ratio of these variants across cell types and developmental stages contributes to tissue‐specific phenotypical changes. This imbalance may impair actin dynamics and mechanosensitive

Nonlinear wavelength conversion in photonic crystal fibers with three zero dispersion points
, 2010 In this theoretical study, we show that a simple endlessly single-mode photonic crystal fiber can be designed to yield, not just two, but three zero-dispersion wavelengths.

FEBS Letters, EarlyView.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.
