Features of sedimentation in the Gren-fjord (West Spitsbergen) [PDF]

open access: yesVestnik MGTU, 2017
Sedimentation in gulfs of the Arctic fjord type is very specific and different from gulfs of moderate and southern latitudes. In this aspect, sedimentation in the Gren-fjord is remarkable due to a set of features.

Axial Anomaly in Galaxies and the Dark Universe

open access: yesUniverse, 2021
Motivated by the SU(2)CMB modification of the cosmological model ΛCDM, we consider isolated fuzzy-dark-matter lumps, made of ultralight axion particles whose masses arise due to distinct SU(2) Yang–Mills scales and the Planck mass MP. In contrast to SU(2)

Encores on Cores [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2006
We give a new derivation of the threshold of appearance of the $k$-core of a random graph. Our method uses a hybrid model obtained from a simple model of random graphs based on random functions, and the pairing or configuration model for random graphs with given degree sequence.

Distribution of eight heavy metals in the inner shelf sediments of East China Sea: Risk assessments and sources analysis

open access: yesEcosystem Health and Sustainability, 2021
Although numerous studies on heavy metals (HMs) in sediments have been carried out in the East China Sea (ECS), the knowledge on the recent pollution levels of HMs in coastal region remains not well understood due to the rapid developments of ...

ACOUSTIC INFLUENCE EFFECT ON POROUS MEDIA PERMEABILITY (REVIEW)

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2022
The relevance of the work is caused by the need to solve the problems arising in the development of oil fields: reducing the production rate; deterioration of reservoir filtration properties; increasing water cut of produced oil.

On approximate cores of non-convex economies [PDF]

open access: yes, 1984
Grodal B, Trockel W, Weber S. On approximate cores of non-convex economies. Economics letters. 1984;15(3-4):197-202.In this note we investigate, for non-convex finite economies, the relationship between the existence of approximate core allocations and ...

ADVANTAGES OF SCAR-PATTERN ANALYSIS IN THE STUDY OF PALEOLITHIC СORES

open access: yesТеория и практика археологических исследований, 2021
Scar-pattern or working step analysis is one of the main components of technological analysis. This analysis is usually applied to reconstruct the technological sequence of Middle and Upper Palaeolithic bifacial tools. In addition to bifacial implements,

Interval-Valued Cores and Interval-Valued Dominance Cores of Cooperative Games Endowed with Interval-Valued Payoffs

open access: yesMathematics, 2018
Cooperative games endowed with interval-valued payoffs are studied in this paper. Based on the interval-valued payoff and the different types of orderings, we can propose many types of so-called interval-valued cores and interval-valued dominance cores ...

Hot cores: probes of high-redshift galaxies? [PDF]

open access: yes, 2005
The very high rates of second generation star formation detected and inferred in high-redshift objects should be accompanied by intense millimetre-wave emission from hot core molecules.
