NGC1052 - A study of the pc-scale twin jet [PDF]
, 2002 We present results of a VLBA multi-frequency study of the pc-scale twin jet in NGC1052. We observed this object at epoch 1998.99 with the VLBA at 5, 8.4, 22 and 43 GHz both in total and linearly polarized intensity.

Dark matter in ghost-free bigravity theory: From a galaxy scale to the universe
, 2014 We study the origin of dark matter based on the ghost-free bigravity theory with twin matter fluids. The present cosmic acceleration can be explained by the existence of graviton mass, while dark matter is required in several cosmological situations [the

Catastrophic rearrangement of a compact star due to the quark core formation [PDF]
, 2005 We study properties of compact stars with the deconfinement phase transition in their interiors. The equation of state of cold baryon-rich matter is constructed by combining a relativistic mean-field model for the hadronic phase and the MIT Bag model for

Does lower educational attainment increase the risk of osteoarthritis surgery? a Swedish twin study
BMC Musculoskeletal Disorders, 2023 Background Previous studies have reported an inverse association between educational attainment and different osteoarthritis (OA) outcomes. However, none of the previous studies have accounted for potential confounding by early-life environment and ...

Twin methodology in epigenetic studies [PDF]
Journal of Experimental Biology, 2015 Since the final decades of the last century, twin studies have made a remarkable contribution to the genetics of human complex traits and diseases. With the recent rapid development in modern biotechnology of high-throughput genetic and genomic analyses, twin modelling is expanding from analysis of diseases to molecular phenotypes in functional ...

Twin Studies in Medical Genetics [PDF]
Acta geneticae medicae et gemellologiae, 1974 It is the aim of twin studies to obtain results which are not only valid for twins, but apply to the whole population. Therefore the following questions have to be answered first: do twins differ from non-twins in the trait under study? Do different nongenetic factors act upon MZ and DZ twins which alter the probability of manifestation of a trait ...
