Translating Riedl: The Circulation and Operationalisation of Evolutionary Ideas

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Rupert Riedl's Order in Living Organisms proposed a systems theory of evolution decades before the concepts it pioneered—homology, burden, the imitative epigenotype—reached the agenda of evolutionary biology. This paper reconstructs the lineages that operationalized his insights across several fields and explores the internal and external reasons for ...

Machine Learning and Deep Learning-Based Atmospheric Duct Interference Detection and Mitigation in TD-LTE Networks

open access: yesFuture Internet
The variations in the atmospheric refractivity in the lower atmosphere create a natural phenomenon known as atmospheric ducts. The atmospheric ducts allow radio signals to travel long distances.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Effects of Rising Temperature on Microwave Communications in Ducting Environment over the Southern Region of Pakistan in the Northern Arabian Sea

open access: yesSir Syed University Research Journal of Engineering and Technology, 2020
The propagation of microwave (MW) of frequencies above 300 MHz is affected by the existence and properties of the atmospheric duct. Atmospheric ducts exist in many areas of the world ocean, including the Arabian Sea.

Analytical Methodology to Determine Thermally Induced Soil Deformation From Laboratory Data

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Experimental laboratory investigations underlie most of the knowledge about the mechanics of soils under non‐isothermal conditions and their thermally induced deformation. Despite advances, the understanding of thermally induced deformation of soils remains inconsistent, hindering the development of a coherent framework that can advance ...

Atmospheric refractivity estimation from AIS signal power using the quantum-behaved particle swarm optimization algorithm

open access: yesOpen Geosciences, 2019
This paper proposes a new refractivity profile estimation method based on the use of AIS signal power and quantum-behaved particle swarm optimization (QPSO) algorithm to solve the inverse problem.

The place bonding potential of nature‐based citizen science with refugee children and youth

open access: yesPeople and Nature, EarlyView.
Abstract Nature‐based citizen science often involves close interaction with places. In addition to providing benefits, such as learning opportunities and contact with nature, it can facilitate and shape bonds between people and places. Research exploring the place bonding potential of such projects is still in its infancy. This paper addresses this gap

CAFs‐mediated histone lactylation reprograms cholesterol metabolism in colorectal cancer to drive CD8+ T cell immunosuppression

open access: yesThe Journal of Pathology, EarlyView.
Abstract The progression of colorectal cancer (CRC) is critically regulated by cancer‐associated fibroblasts (CAFs) within the tumor microenvironment (TME), yet the specific molecular mechanisms by which CAFs influence CRC remain unclear. This study reveals the mechanism by which CAFs promote CRC malignant progression and immune suppression through ...
