Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Real-time Pulse Search and Positioning Method for Baseband Data Based on Matched Filtering

The Astronomical Journal
Fast radio bursts (FRBs) are the most intense radio explosions known, yet their origins remain a significant astrophysical mystery. High-time-resolution pulse searching has opened new avenues for studying narrow and faint pulses, promising substantial ...

A SEARCH FOR FAST RADIO BURSTS AT LOW FREQUENCIES WITH MURCHISON WIDEFIELD ARRAY HIGH TIME RESOLUTION IMAGING [PDF]

, 2015
We present the results of a pilot study search for fast radio bursts (FRBs) using the Murchison Widefield Array (MWA) at low frequencies (139–170 MHz). We utilized MWA data obtained in a routine imaging mode from observations where the primary target was

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

High resolution bus lane performance evaluation from real time update data

Transportation Research Interdisciplinary Perspectives
Bus priority measures such as bus lanes are designed to enhance bus performance and increase ridership. Traditionally, benefits have been evaluated at an aggregate level. Newer data sources, however, enable the tracking of micro delays and their relation

Multiscaling analysis of high resolution space-time lidar-rainfall [PDF]

Nonlinear Processes in Geophysics, 2009
In this study, we report results from scaling analysis of 2.5 m spatial and 1 s temporal resolution lidar-rainfall data. The high resolution spatial and temporal data from the same observing system allows us to investigate the variability of rainfall at ...

A Bayesian fusion model for space-time reconstruction of finely resolved velocities in turbulent flows from low resolution measurements

, 2015
The study of turbulent flows calls for measurements with high resolution both in space and in time. We propose a new approach to reconstruct High-Temporal-High-Spatial resolution velocity fields by combining two sources of information that are well ...
