An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

The Anatomical Record, Volume 309, Issue 7, Page 1910-1924, July 2026.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

Calculating the Uncertainty of a Structure from Motion (SfM) Model, Cadman Quarry, Monroe, Washington

, 2016
Structure from Motion (SfM) is a new form of photogrammetry that automates the rendering of georeferenced 3D models of objects using digital photographs and independently surveyed Ground Control Points (GCPs).

Segmentation in structure from motion: modeling and psychophysics

, 2001
Much work has been done on the question of how the visual system extracts the three-dimensional (3D) structure and motion of an object from two-dimensional (2D) motion information, a problem known as ‘Structure from Motion’, or SFM.

Cohort profile: a community‐based prospective cohort study of Alzheimer's disease and related dementias in the Democratic Republic of Congo

Alzheimer's &Dementia: Behavior &Socioeconomics of Aging, Volume 2, Issue 2, June 2026.
Abstract INTRODUCTION The Étude du Vieillissement Cognitif et de Démence en République Démocratique du Congo (EVCD‐RDC) launched in 2024 to investigate socio‐environmental and biological determinants of dementia in Kinshasa. METHODS The study recruited 1000 adults aged ≥65 years across four diagnostic groups – cognitively unimpaired (CU), mild ...

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

Structure from motion using sequential monte carlo methods

, 2001
. In this paper, the structure from motion (SfM) problem is addressed using sequen-tial Monte Carlo methods. A new SfM algorithm based on random sampling is derived to estimate the posterior distributions of camera motion and scene structure for the ...

Quantification of ground surface movements on sorted circles using time‐lapse structure‐from‐motion photogrammetry in a karst cave, Slovenia

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
We present ground surface movements on sorted circles in a karst cave using time‐lapse photogrammetry with accuracies of up to ±2 mm. Data with 3‐hourly resolution revealed average vertical movements of up to 50 mm and horizontal movements of up to 15 mm during individual freeze–thaw cycles.

Climatic, lithologic and topographic control on alpine rock fracturing and talus evolution

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Investigating Holocene rockwall–talus systems in an Alpine valley revealed that lithologic and topographic conditions in concert with climatic‐driven stresses and time since deglaciation result in rockwall fracture patterns that control rockfall size, erosion rates and the characteristics and evolution of talus.
