Advancing Forest Inventory and Fuel Monitoring with Multi-Sensor Hybrid Models: A Comparative Framework for Basal Area Estimation

Remote Sensing
Fire suppression in the upper U.S. Midwest has led to the expansion of flammable coniferous ladder fuels, necessitating precise tracking of conifer species basal area (BA) for fire risk management.

Gluing support τ-tilting modules via symmetric ladders of height 2

Science China Mathematics
Gluing techniques with respect to a recollement have long been studied. Recently, ladders of recollements of abelian categories were introduced as important tools. We present explicit constructions of gluing of support $τ$-tilting modules via symmetric ladders of height two.

Climbing the Entrepreneurial Ladder: The Role of Gender [PDF]

We investigate whether women and men differ with respect to the steps they take in the entrepreneurial process, distinguishing between five successive steps described by the following positions: (1) "never thought about it"; (2) "thinking about starting ...

Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

Plant, Cell &Environment, Volume 49, Issue 10, Page 7526-7538, October 2026.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

Moving-Boundary Fluctuation Analysis: Premium Drift, Ladder Structure, and Ruin in Phase-Type Cumulative Shock Models

Mathematics
We extend the phase-tagged fluctuation framework for cumulative shock models from a fixed failure threshold to a linearly moving boundary u0+cτn, the premium drift regime that underlies insurance ruin theory.

Demo 04-18 Ladder Forces

, 2001
When a ladder is leaned against a wall, as shown in Figure 1, several forces are exerted on the ladder by the wall and the floor.

Stepwise On‐Surface Synthesis and Transformations of Two‐Dimensional Covalent Organic Frameworks by Controlled Thermal Stimuli

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...

Some geometric ladder problems [PDF]

, 2018
Several ladder and box problems are presented. There is a box at the foot of a vertical wall. We calculate the minimal length of the ladder that touches the wall over the box and the height of the point where the ladder of a given length touches the wall.
