Compressed Sensing for Images with Chirps and Reed-Muller Codes

, 2019
Compressed sensing is nothing but a signal processing technique which compresses the signal and reconstructs the signal. It is a new technique to receive signals that are sparse with a less number of measurements.

Study of a Frugal Design Picosecond Laser System for Laser‐Assisted Corneal Surgery

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Stromal surface after extraction of the lamella cut with the studied frugal picosecond laser source. ABSTRACT Femtosecond lasers have long been the gold standard for corneal laser‐assisted surgery, but their high cost limits widespread use. This study challenges their supremacy by investigating a cost‐effective alternative: a frugal all‐fiber ...

MVB Maturation Responsive to KRASG12D/TP53R175H Co‐mutations Fuels Extracellular Vesicle‐hypersecretion Phenotype to Aggravate Lymphangiogenesis and Lymphatic Metastasis

Journal of Extracellular Vesicles, Volume 15, Issue 10, October 2026.
KRAS/TP53 co‐mutation specifically induces transcriptional upregulation of FUS, which mediates EVs‐circSCARNA10 secretion to anchor lymphatic endothelial cells via promoting VEGFR3 transcription, ultimately inducing lymphangiogenesis and LN metastasis of KRASG12D and TP53R175H co‐mutated PDAC.

Satellite and Reanalysis Dataset Dependence of ETCCDI Extreme Precipitation Trends in Paraná, Southern Brazil

International Journal of Climatology, Volume 46, Issue 12, October 2026.
Extreme precipitation trends detected in Paraná, Southern Brazil (1983–2024), are strongly conditioned by the dataset used, with reanalyses indicating coherent inland drying and longer dry spells, observations retaining stronger mesoscale heterogeneity, and satellite products often showing declines in short‐duration extremes. Monthly diagnostics reveal

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

Journal of Raman Spectroscopy, Volume 57, Issue 10, Page 1644-1653, October 2026.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO 2 and the v2 mode of CH 4. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH 4 and CO 2 spectra in a diffusion flame.

Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...
