Railway traffic disturbance management by means of control strategies applied to operations in the transit system [PDF]

open access: yes, 2018
Railway systems in metropolitan areas support a high density of daily traffic that is exposed to different types of disturbances in the service. An interesting topic in the literature is to obtain action protocols in the presence of contingencies which ...

Investigating boreal forest successional stages in Alaska and Northwest Canada using UAV‐LiDAR and RGB and a community detection network

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study develops a novel application of UAV‐LiDAR and Red Green Blue (RGB) data and network analysis to enhance our understanding of boreal forest succession. The results indicate that tree height and spectral variables are the most influential predictors of plant functional type in random forest algorithms, and high overall accuracies were attained.

Don't calm down! How affective climate emerges in start‐ups

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Different types of affective climates—norms related to the experience, expression, use, and regulation of emotions—have been shown to impact organizational outcomes. However, we know less about how these climates emerge. This study investigates the emergence of affective climates through a 22‐month longitudinal multiple‐case ...

Rapid Mechanochemical Synthesis of Oxyhalide Superionic Conductor: Time‐Resolved Structural Evolution

open access: yesSmall Methods, EarlyView.
Time‐resolved synchrotron X‐ray scattering coupled with mechanochemical synthesis reveals the structural evolution of oxyhalide superionic conductors. Oxygen incorporation governs reaction kinetics, amorphization, and microstructural transformations, while enabling efficient Li‐ion diffusion. This study highlights critical correlations between reaction

Pitardia resurrected: A new member of subtribe Menthinae (Lamiaceae)

open access: yesTAXON, EarlyView.
Abstract Despite tremendous progress towards clarifying phylogenetic relationships within the mint family (Lamiaceae), uncertainty remains regarding relationships among some major clades as well as the proper placement of some genera. While researching the genus Nepeta, a species from northeastern Morocco, N.

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species
