Retrieval of Aerosol Optical Depth in the Arid or Semiarid Region of Northern Xinjiang, China

Remote Sensing, 2018
Satellite remote sensing has been widely used to retrieve aerosol optical depth (AOD), which is an indicator of air quality as well as radiative forcing.

Statistical Characterization of Surface Reflectance

, 2014
The classification of surface reflectance functions as diffuse, specular, and glossy has been introduced by Heckbert more than two decades ago. Many rendering algorithms are dependent on such a classification, as different kinds of light transport will ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Evaluating Environmental Weathering Effects on White Portland Cement using Hyperspectral Reflectance Analysis [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Cement is a primary binding material that plays a crucial role in construction. This study used hyperspectral reflectance analysis to investigate the spectral reflectance characteristics of White Portland Cement (WPC) exposed to environmental conditions.

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

Molecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

A Stepwise BRDF-Based Land Surface Reflectance Model Over Rugged Terrain

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The land surface reflectance is an essential variable of remote sensing, which is significantly affected by topography and atmosphere. Rugged terrain significantly alters the radiative transfer among the solar-terrain-sensor, resulting in large errors in

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.
