Oscillations in the dark energy EoS: new MCMC lessons

, 2010
We study the possibility of detecting oscillating patterns in the equation of state (EoS) of the dark energy using different cosmological datasets. We follow a phenomenological approach and study three different oscillating models for the EoS, one of ...

The history and nomenclatural significance of herbarium collections made by Alexander A. Tatarinow in North China and Mongolia in 1841–1850

TAXON, Volume 73, Issue 2, Page 556-572, April 2024.
Abstract Alexander A. Tatarinow (1817?–1886) made an extensive collection of vascular plants and insects in North China and Mongolia while serving as a physician in the 12th Russian Orthodox Ecclesiastical Mission in Beijing during 1841–1850. Tatarinow's plant collection included about 800 species and became the basis for 70 new species, of which 12 ...

Determination of the reaction plane in ultrarelativistic nuclear collisions

, 1993
In the particles produced in a nuclear collision undergo collective flow, the reaction plane can in principle be determined through a global event analysis.

A Cost Model for Ocean Iron Fertilization as a Means of Carbon Dioxide Removal That Compares Ship‐ and Aerial‐Based Delivery, and Estimates Verification Costs

Earth's Future, Volume 12, Issue 4, April 2024.
Abstract We present a cost model for implementing a deployment scale effort for conducting ocean iron fertilization (OIF) for marine‐based carbon dioxide removal (CDR). The model incorporates basic oceanographic parameters critical for estimating the effective export of newly fixed CO2 into biomass that is stimulated by Fe addition to an Fe‐limited ...

Shifting Depth Distributions of Deep‐Sea Corals in the Southwest Pacific: Implications for Deglacial Dynamics of the Southern Ocean

Paleoceanography and Paleoclimatology, Volume 39, Issue 4, April 2024.
Abstract We compare depth and temporal distributions of sub‐fossil assemblages of two cold‐water scleractinian corals on seamounts in the Southwest Pacific to help define the temporal variations of water mass properties in the Southern Ocean (SO) during deglaciation.

Mutual inductance calculation for rectangular and circular coils with parallel axes

IET Electric Power Applications, Volume 18, Issue 4, Page 379-388, April 2024.
Analytical and truncated region eigenfunction expansion (TREE) methods have been provided for calculating mutual inductance between circular and rectangular coils. Accurate and fast computation is verified by FEM and experiments. Abstract Simple and practical methods have been provided for the mutual inductance between rectangular and circular coils ...

Diagnostics Of Disks Around Hot Stars [PDF]

, 2005
We discuss three different observational diagnostics related to disks around hot stars: absorption line determinations of rotational velocities of Be stars; polarization diagnostics of circumstellar disks; and X-ray line diagnostics of one specific ...

A photometric and spectroscopic study of WW And - an Algol-type, long period binary system with an accretion disc

, 2012
We have analyzed the available spectra of WW And and for the first time obtained a reasonably well defined radial velocity curve of the primary star.
