[1] In this study we utilize two organic geochemical proxies, the U37 k′ index and TEX86, to examine past sea surface temperatures (SST) from a site located near the Nile River Delta in the eastern Mediterranean (EM) Sea. The U37 k′ and TEX86 records generally are in agreement and indicate SST ranges of 14°C–26°C and 14°C–28°C, respectively, during the last 27 cal ka. During the Holocene, TEX86...

Subjective thermal sensation of late teenagers was examined aiming to reveal potential discrepancies in its estimation compared to adults. Since teenagers have different clothing habits and preferences from adults, it is important to know whether the conclusions reached by studies on thermal sensation, usually involving adults, can be also applied to teenagers. A group of late teenagers was int...

[1] Stable isotope, trace metal, alkenone paleothermometry, and radiocarbon methods have been applied to sediment cores in the western subpolar North Atlantic between Hudson Strait and Cape Hatteras to reveal the history of climate in that region over the past 11 kyr. We focus on cores from the Laurentian Fan, which is known to have rapid and continuous accumulation of hemipelagic sediment. Alt...

In this theoretical study of successful core-collapse supernovae, the authors provide a detailed model neutrino emission from different phases transition - explosion to proto-neutron star cooling late-time formation either neutron or black hole. They show that for supernova in Milky Way, these copiously produced neutrinos can be detected by current neutrino-detection experiments and used extrac...

[1] The current structure of the South Armorican Domain in the French Variscan Belt, provides an excellent record of the late orogenic evolution, as documented by the complex interactions between extensional structures and partial melting. In the Golfe du Morbihan, the South Brittany Migmatite Belt (SBMB), tectonically overlain by non‐melted metamorphic units, was studied by combined structural...

Most tools available for quantifying large linked Fault Tree models as used in Probabilistic Safety Assessment (PSA) are unable to produce analytically exact results. The algorithms of such quantifiers are designed to neglect sequences when their likelihood decreases below a predefined truncation limit. In addition, the rare event approximation is typically implemented to the first order, ignor...

We present a timeseries of flood and slumping phases in central Europe for the past 65,000 years from event layers sediment cores infilled Eifel maar basins (Germany). Palynological, petrographic organic carbon (chlorins) records are used to understand precise timing these events. Periods increased activity seem coincide with Heinrich stadials marine records, which associated cold more arid cli...
