A novel red-edge-based anomalous water detection index and diagnostic framework
International Journal of Digital EarthFrequent water anomalies pose serious threats to human habitats. Owing to the complexity of aquatic environments and the diversity of anomaly types, satellite remote sensing still faces challenges.

Spectral Banach Algebras of Bounded Index
Journal of Algebra, 1993 The author deals mostly with \(I\)-rings (associative rings with the property that for every non-nilpotent element \(a\) there is a non-zero \(b\) with \(b = bab\)). We mention here some results of the paper with a Banach algebra flavour. Call a Banach algebra \(A\) spectral, if for every closed ideal \(I \subset A\) the quotient \(A/I\) is an \(I ...

Dust evolution in the transition towards the denser ISM: impact on dust temperature, opacity, and spectral index [PDF]
, 2015 Context. Variations in the observed dust emission and extinction indicate a systematic evolution of grain properties in the transition from the diffuse interstellar medium (ISM) to denser molecular clouds. Aims.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...

Evaluation of Sub-Pixel Cloud Noises on MODIS Daily Spectral Indices Based on in situ Measurements
Remote Sensing, 2011 Cloud contamination is one of the severest problems for the time-series analysis of optical remote sensing data such as vegetation phenology detection. Sub-pixel clouds are especially difficult to identify and remove.

A new spectral index for the extraction of built-up land features from Landsat 8 satellite imagery
Geocarto International, 2018 Extracting built-up areas from remote sensing data like Landsat 8 satellite is a challenge. We have investigated it by proposing a new index referred as built-up land features extraction index (BLFEI).

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.

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.
