A Kähler Einstein structure on the tangent bundle of a space form

International Journal of Mathematics and Mathematical Sciences, 2001
We obtain a Kähler Einstein structure on the tangent bundle of a Riemannian manifold of constant negative curvature. Moreover, the holomorphic sectional curvature of this Kähler Einstein structure is constant.

Pseudo-Einstein manifolds

Topology and its Applications, 2015
Abstract Among the studies on pseudo-Hermitian geometry of strictly pseudo-convex almost CR manifolds, we study especially the two kinds of pseudo-Einstein structures and related problems.

Upregulated NOTCH2 Expression Is Implicated in the Clinical Aggressiveness of Atypical Fibroxanthoma and Pleomorphic Dermal Sarcoma

International Journal of Dermatology, EarlyView.
ABSTRACT Background Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) represent clinicopathological variants of a spectrum. It is known that AFX and PDS tumors harbor frequent NOTCH1/2 mutations. However, the expression of Notch signaling pathway‐associated proteins in both tumor cells has not been studied before.

What has Nicaea to do with Canterbury? Creeds, Councils, Tradition, and the Fathers in the Church of England and the Anglican Communion

International Journal of Systematic Theology, EarlyView.
Abstract This article charts the Council of Nicaea's (325) relevance to the Anglican Tradition from the sixteenth century to the present day, as manifested through Anglicanism's engagement with the Nicene Creed, its attitude towards early ecumenical councils, its appeals to ‘the Fathers’ and its approach to ‘tradition’, particularly in relation to ...

Curvature properties of \(\alpha\)-cosymplectic manifolds with \(\ast\)-\(\eta\)-Ricci-Yamabe solitons

Cubo
In this research article, we study \(\ast\)-\(\eta\)-Ricci-Yamabe solitons on an \(\alpha\)-cosymplectic manifold by giving an example in the support and also prove that it is an \(\eta\)-Einstein manifold.

Some Curvature Conditions on a Para-Sasakian Manifold with Canonical Paracontact Connection

International Journal of Mathematics and Mathematical Sciences, 2012
We study canonical paracontact connection on a para-Sasakian manifold. We prove that a Ricci-flat para-Sasakian manifold with respect to canonical paracontact connection is an η-Einstein manifold.

Parental Health Shocks and Child Outcomes at Ages 17–25: Evidence From Germany

Journal of Marriage and Family, EarlyView.
ABSTRACT Objective To investigate the impact of various parental health shocks, including parental death, on young adults' life satisfaction and mental health, personality traits, as well as NEET status (i.e., being neither in employment, education, nor training).

Distributional Cues in Construction Acquisition: A Comparative Study of Native and Nonnative English Speakers Using the As‐Predicative Construction

Language Learning, EarlyView.
Abstract This study investigates how distributional cues are integrated into the mental representation of the as‐predicative construction by English native and nonnative speakers, drawing on associative learning theory. We examined speakers’ constructional retrieval when given a verbal cue (Experiment 1) and their verb retrieval when given a ...
