Ecography, EarlyView.Land‐use changes and climatic changes are two entwined stressors on ecosystems. Studies on such interactions often focus on species‐level or region‐specific responses, but fewer have examined differences in responses based on functional traits. Here we examine the influence of natural habitat cover and temperature change on the abundance of all ...

Mathematics OpenThe numerical range of a matrix is a compact convex set in the complex plane that contains the convex hull of the spectrum of the matrix. A key question is whether the origin belongs to the convex hull of the spectrum or the numerical range.

Improvement of volume estimation of stockpile of earthworks using a concave hull- footprint [PDF]
Micro, Macro & Mezzo Geoinformation, 2015 In the estimation of volume of stockpiles of earthworks, the question is no longer whether the data collected is dense and accurate (equipment and techniques capable of accurate data measurement are available), but how to manipulate the data to yield ...

Novel three‐dimensional ECG algorithm for reliable screening for cardiac amyloidosis
ESC Heart Failure, EarlyView.The present manuscript describes the derivation and validation of an algorithm for screening of cardiac amyloidosis using 3‐dimensional ECG. The algorithm is based on a ECG vector loop, acquired over the duration of 15 seconds using 4 electrodes. With this easy to perform method, we describe a high diagnostic accuracy for the detection of cardiac ...

LAX phases: A family of novel stable layered materials, informatics‐based discovery
InfoMat, EarlyView.This research presents LAX phases, innovative layered materials from late transition metals, as alternatives to MAX phases. Using crystal structure prediction and machine learning, we identified 207 stable LAX systems with superior mechanical properties. These findings open pathways for LXene synthesis, promising advancements in catalysis and materials

Powers of Convex-Cyclic Operators
Abstract and Applied Analysis, 2014 A bounded operator T on a Banach space X is convex cyclic if there exists a vector x such that the convex hull generated by the orbit Tnxn≥0 is dense in X. In this note we study some questions concerned with convex-cyclic operators. We provide an example

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Lateral patellofemoral ligament (LPFL) reconstruction addresses medial patellar instability, but uncertainty regarding the optimal femoral attachment site may affect isometry and increase complication rates. This study aimed to establish landmarks for the femoral attachment of the LPFL graft based on in vivo isometry during active knee
