Sub-millijoule-level Fe:ZnSe chirped pulse amplifier seeded by KTA-based OPA system [PDF]
We developed a Fe:ZnSe chirped pulse amplifier with a KTA-based optical parametric amplifier, achieving 0.6 mJ pulses at 4-micron wavelength. It should be inherently carrier envelope phase stable and applicable to strong field science.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Think Outside the Fiber: Imaging Amplifier for Space-Multiplexed Optical Transmission
This paper proposes a simple and practical method to amplify signals for space-multiplexed optical transmission. In this amplification technique, the output facet of the multicore or multimode fiber is mapped back to the same type of fiber after passing ...

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

A Low-Power CMOS Trans-Impedance Amplifier for 2.5 Gb/S Optical Communication Systems [PDF]
This Paper presents a new Trans-impedance amplifier for optical receiver circuits. The amplifier is based on parallel (R-C) feedback topology which is optimized for power consumption and uses shunt-peaking technique to enhance the frequency bandwidth of ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Passive alignment stability and auto-alignment of multipass amplifiers based on Fourier transforms
The stability properties of Fourier-based multipass amplifier to misalignments (tilts) of its optical components has been investigated. For this purpose, a method to quantify the sensitivity to tilts based on the amplifier small signal gain has been ...
