AI Article Synopsis

  • A new method for creating an all-optical flip-flop using dynamic Brillouin gratings in polarization maintaining fibers has been proposed and successfully tested.
  • The flip-flop demonstrates long storage times and a wide bandwidth due to the fiber's uniform birefringence, allowing for effective data storage and retrieval.
  • Experimental results show the system operates with 300 ps phase-modulated pulses in a 1-meter long DBG, achieving a time-bandwidth product of approximately 30, with current limitations mainly due to the pulse bandwidth and length of the fiber.

Article Abstract

A method to generate an all-optical flip-flop is proposed and experimentally demonstrated based on dynamic Brillouin gratings (DBGs) in polarization maintaining fibers. In a fiber with sufficiently uniform birefringence, this flip-flop can provide extremely long storage times and ultra-wide bandwidth. The experimental results demonstrate an all-optical flip-flop operation using phase-modulated pulses of 300 ps and a 1 m long DBG. This has led to a time-bandwidth product of ∼30, being in this proof-of-concept setup mainly limited by the relatively low bandwidth of the used pulses and the short fiber length.

Fires are increasingly affecting tropical biomes, where landscape-fire interactions remain understudied. We investigate the fire-proneness-the likelihood of a land use or land cover (LULC) type burning more or less than expected based on availability-in the Brazilian Atlantic Forest (AF). This biodiversity hotspot is increasingly affected by fires due to human activities and climate change.

Impacts of climate change on storm event-based flow regime and channel stability of urban headwater streams.

Tetra Tech, Inc., P.O. Box 14409, Research Triangle Park, NC, 27709, United States. Electronic address:

Due to the recent improved availability of global and regional climate change (CC) models and associated data, the projected impact of CC on urban stormwater management is well documented. However, most studies are based on simplified design storm analysis and unit-area runoff models; evaluations of the long-term, continuous hydrologic response of extensive stormwater control measures (SCM) implementation under future CC scenarios are limited. Moreover, channel stability in response to CC is seldom evaluated due to the input data required to develop a long-term, continuous sediment transport model.

The P2X4 receptor is implicated in various pathological conditions, including neuropathic pain and cancer. This study reports the development of 1,4-naphthodiazepinedione-based P2X4 receptor antagonists aimed at both therapeutic applications and potential use as PET tracers for imaging P2X4 receptor expression in cancer. Structure-activity relationship studies aided by docking studies and molecular dynamics simulations led to a series of compounds with potent P2X4 receptor antagonism, promising inhibition of interleukin-1β release in THP-1 cells and suitability for radiolabeling with fluorine-18.

Chemically induced dimerization/proximity (CID/CIP) systems controlled by chemical dimerizers (also known as molecular glues) provide valuable means for understanding and manipulating complex, dynamic biological systems. In this study, we present the development of versatile chemo-optogenetic systems utilizing azobenzene-based photoswitchable molecular glues (sMGs) for reversible protein dimerization controlled by visible light. These systems allow multiple cycles of light-induced dimerization, overcoming the limitations of irreversible photolysis in previous systems.

Genetically encoded tension sensors (GETSs) allow for quantifying forces experienced by intracellular proteins involved in mechanotransduction. The vast majority of GETSs are comprised of a FRET pair flanking an elastic "spring-like" domain that gradually extends in response to force. Because of ensemble averaging, the FRET signal generated by such analog sensors conceals forces that deviate from the average, and hence it is unknown if a subset of proteins experience greater magnitudes of force.
