Fraternal cooperation of hierarchical cancer parallels metazoan multicellularity and eusociality

open access: yesBiological Reviews, EarlyView.
ABSTRACT Metazoan multicellularity and eusociality — both outcomes of the fraternal major transitions — have numerous features in common such as uneven distribution of group‐establishing potential. In addition to this framework, I argue herein that the group‐forming principles of metazoan multicellularity and eusociality are analogous to hierarchical ...

On Pseudo Cyclic Ricci Symmetric Manifolds

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2011
: The object of the present paper is to study concircularly symmetric (PCRS)n, concircularly recurrent (PCRS)n, decomposable (PCRS)n. Among others it is shown that in a decomposable (PCRS)n one of the decompositions is Ricci flat and the other ...

Methods of holonomy theory for Ricci-flat Riemannian manifolds [PDF]

open access: yesJournal of Mathematical Physics, 1991
Compact, Ricci-flat Riemannian manifolds often arise in physical applications, either as a technical device or as models of ‘‘internal’’ space. The idea of extending the holonomy group of such a manifold to a larger gauge group (‘‘embedding the connection in the gauge group’’) plays a fundamental role in the ‘‘manifold compactification’’ approach to ...

Height, weight, and body mass index trajectories and their correlation with functional outcome assessments in boys with Duchenne muscular dystrophy

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
The analysis of height, weight, and BMI z‐score trajectories in boys with DMD from the FOR‐DMD study showed that higher baseline height was associated with slower subsequent growth, and older age with greater weight gain after glucocorticoid initiation.

On Almost C(α)-Manifold Satisfying Certain Curvature Conditions

open access: yesCumhuriyet Science Journal
This research article is about the geometry of the almost C(α)- manifold. Some important properties of the almost C(α)- manifold with respect to the W_3- curvature tensor, such as W_3-flat and W_3- semi-symmetry, are investigated.

Ricci-flat manifolds of generalized ALG asymptotics

open access: yes, 2022
In complex dimensions $\geq 3$, we provide a geometric existence for generalized ALG complete non-compact Ricci flat Kähler manifolds with Schwartz decay i.e. metric decay in any polynomial rate to an ALG model $\mathbb{C}\times Y$ modulo finite cyclic group action, where $Y$ is Calabi-Yau.

The crop wild relative Fragaria vesca as source of resistance against strawberry anthracnose

open access: yesPlant Biology, EarlyView.
The crop wild relative Fragaria vesca is a valuable resource to mine for novel resistance factors against Colletotrichum. Abstract The genetic diversity of Fragaria species in situ has great potential for breeding resistance in cultivated strawberries against anthracnose disease.

Quasi-local mass integrals and the total mass

open access: yes, 2016
On asymptotically flat and asymptotically hyperbolic manifolds, by evaluating the total mass via the Ricci tensor, we show that the limits of certain Brown-York type and Hawking type quasi-local mass integrals equal the total mass of the manifold in all ...
