Journal of Quaternary Science, EarlyView.ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

EPJ Web of Conferences, 2013 Time has always played a crucial role in cosmology. I review some of the aspects of the present cosmological model which are more directly related to time, such as: the definition of a cosmic time; the existence of typical timescales and epochs in an expanding universe; the problem of the initial singularity and the origin of time; the cosmological ...

Journal of Quaternary Science, EarlyView.ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Journal of High Energy PhysicsWe study the cosmological gravitational particle production (CGPP) of spin- 3 2 $$ \frac{3}{2} $$ particles during and after cosmic inflation, and map the parameter space that can realize the observed dark matter density in stable spin- 3 2 $$ \frac{3}{2}

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature
Mathematische Nachrichten, EarlyView.ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

Exploring f(Q) gravity through model-independent reconstruction with genetic algorithms
Physics Letters BIn this paper, we use a machine learning technique, specifically genetic algorithms, to reconstruct the functional form of f(Q) gravity in a model-independent manner. To achieve this, we use Hubble measurements derived from cosmic chronometers and radial

International Journal of Theoretical Physics, 2010 We investigate the connection between the entanglement generated by expanding universe and the cosmological parameters. We show that the faster the universe expands and the larger the total volume results the higher degree of entanglement.

People and Nature, EarlyView.Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...

Thermodynamic topology of black holes within Tsallis statistics
Physics Letters BIn this paper, we investigate the thermodynamic topology of black holes within the framework of Tsallis statistics. By integrating Tsallis non-extensive statistics with topological thermodynamics, we analyze the local and global stability of various ...

Integrating human acceptance into habitat suitability models for snow leopards in northern Bhutan
People and Nature, EarlyView.Abstract Habitat suitability models are commonly used to assess the potential distribution of large carnivores by identifying ecologically favourable areas. However, these models often overlook human dimensions, such as conflict and acceptance, which can lead to overestimation of species ranges and a mismatch between predicted and actual distributions.
