Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Student interpretations of a dynamic geometry environment

open access: yes, 1999
It seems that aspects of student interpretations of computer-based learning environments may result from the idiosyncrasies of the software design rather than the characteristics of the mathematics. Yet, somewhat paradoxically, it is because the software

SINDy-Based Motion-Dependent Nonholonomic Constraint Covariance Adaptation for GNSS-Denied MEMS/INS Vehicle Navigation

open access: yesMicromachines
Low-cost microelectromechanical-system inertial measurement units (MEMS IMUs) enable self-contained vehicle navigation, but their errors accumulate rapidly when global navigation satellite system (GNSS) updates are unavailable.

Smaller is better: nanobodies meet NMR

open access: yesFEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Sensor-Aware Spectral Library-Guided Abundance Inference for Multispectral Target Detection

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Multispectral image (MSI) target detection is challenging not only due to the limited number of spectral bands but also because broad sensor spectral response functions (SRFs) integrate high-dimensional spectral signatures into a low-dimensional ...

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

open access: yesFEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

open access: yesFEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Path planning in dynamic environments.

open access: yes, 2007
Path planning plays an important role in various fields of application, such as CAD design, computer games and virtual environments, molecular biology, and robotics. In its most general form, the path planning problem is formulated as finding a collision-free path for a moving entity between a start and a goal configuration in an environment containing
