Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Virtual element method for the Laplacian eigenvalue problem with Neumann boundary conditions
The Laplacian eigenvalue problem is fundamental to the free vibration problem. The finite element method (FEM) is a classical numerical method for solving eigenvalue problems.

Polygon Mesh Generation of Branching Structures [PDF]
We present a new method for producing locally non intersecting polygon meshes of naturally branching structures. The generated polygon mesh follows the object's underlying structure as close as possible, while still producing polygon meshes that can be visualized efficiently on commonly available graphic acceleration hardware.

From shadows to data: first robust population assessment of snow leopards in Pakistan
The snow leopard Panthera uncia is a flagship species of the greater Himalayan region and symbolizes the integrity of this ecological system. Within the greater Himalayas, Pakistan holds special significance as the north of the country represents a confluence of three major mountain ranges (Hindu Kush, Pamir–Karakoram, and Himalaya).

ABSTRACT As new regulations emerge to address deforestation and unsustainable land use, their interaction with existing national frameworks remains uncertain. This study examines the (in)coherence between the European Union Regulation on deforestation‐free products (EUDR) and domestic deforestation and land use regulations in Brazil, Cameroon and Gabon.

ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

An Effective Method for Slicing Triangle Meshes Using a Freeform Curve
Slicing 3D polygonal meshes is a fundamental operation in various applications such as virtual surgery, garment simulation, and game development. Existing methods primarily slice meshes using either a single line or a set of line segments approximating a

Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.
