The impact of survey design on robustness to mis‐specified detection functions in spatial capture–recapture

open access: yesEcosphere, Volume 17, Issue 10, October 2026.
Abstract Spatial capture–recapture (SCR) density estimators are commonly advertised as being remarkably robust to model mis‐specifications, such as an incorrect choice of detection function. However, at least one previous study has identified a scenario in which a mis‐specified detection function introduces bias.

Hip Fracture Management in Older Adults in Resource‐Constrained Settings: Determinants, Care Pathways, and Outcomes—A Systematic Review and Meta‐Analysis

open access: yesHealth Science Reports, Volume 9, Issue 10, October 2026.
ABSTRACT Background and Aims Hip fractures in older adults cause substantial mortality and functional decline, particularly where access to timely surgery is limited. This review synthesized the determinants, management pathways, and outcomes of hip fractures in resource‐constrained settings and evaluated the association between non‐operative ...

Elimination of TOA corrosion limits [PDF]

open access: yes, 1959
In 1958, planned large scale use of the new I & E slug geometry at more severe operating conditions than had been generally experienced suggested a possible compromise in reactor life and safety if a reasonable degree of rupture control with the new type of element was not maintained.

Catchment Hysteresis From Pathway Branching and Storage Trapping: A Two‐Parameter Mittag‐Leffler Closure and Its Application to the Great Catchment Hysteresis Challenge

open access: yesHydrological Processes, Volume 40, Issue 10, October 2026.
Answering the great catchment hysteresis challenge, we derive a catchment closure whose memory kernel follows from counting flow pathways and measuring how long water is detained. Applied to four Cumbrian micro‐catchments, it shows that the observed hysteresis index conflates event retention with genuine memory, and separating them weakens the inferred

Hybrid TOA/AOA estimation error test and non-line of sight identification in wireless location

open access: yes, 2009
[[abstract]]In this paper, a modified time-of-arrival (TOA) estimation error test and a hybrid time-of-arrival-angle-of-arrival (TOA-AOA) estimation error test for identification of line of sight (LOS) base stations (BSs) are proposed.

Kernel Bounds for Parabolic Operators Having First‐Order Degeneracy at the Boundary

open access: yesMathematische Nachrichten, Volume 299, Issue 10, Page 2894-2917, October 2026.
ABSTRACT We study kernel estimates for parabolic problems governed by singular elliptic operators ∑i,j=1N+1qijDij+cDyy,cγ+1>0,γ=qN+1,N+1,$$\begin{equation*} \sum _{i,j=1}^{N+1}q_{ij}D_{ij}+c\frac{D_y}{y},\qquad \frac{c}{\gamma }+1>0, \quad \gamma =q_{N+1,N+1}, \end{equation*}$$in the half‐space R+N+1={(x,y):x∈RN,y>0}$\mathbb {R}^{N+1}_+=\lbrace (x,y ...

Joint Time-of-Arrival and Carrier-Phase Measurement and Tracking for Enhanced Loran Signals in Complex Interference Environments

open access: yesSensors
To address carrier-phase loss of lock and long-term drift in frequency-offset estimation that may arise from time-of-arrival (TOA) measurements in enhanced Loran (eLoran) timing receivers under low signal-to-noise ratio (SNR) and moderate-to-high ...
