Exotic 4 -Manifolds from Genus-4 Lefschetz Fibrations
Cumhuriyet Science JournalIn this paper, we study minimal simply connected 4-manifolds with b_2^+=3 which admit genus-4 Lefschetz fibrations over the 2-sphere. We first explicitly construct a genus-4 Lefschetz fibration over the 2-sphere using the monodromy of generalized ...

Autosomal Recessive Spastic Ataxia of Charlevoix‐Saguenay in Two Half‐Siblings
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Autosomal recessive spastic ataxia of Charlevoix‐Saguenay (ARSACS) is caused by biallelic pathogenic variants in the SACS gene. We report the clinical, radiologic and neurophysiologic features of a pair of half‐siblings who presented with progressive cerebellar ataxia, peripheral neuropathy and upper motor neuron signs.

Nuclear Physics B, 2019 We introduce a class of F-theory vacua which may be viewed as a specialization of the so-called E6 fibration, and construct a weak coupling limit associated with such vacua which we view as the ‘square’ of the Sen limit. We find that while Sen's limit is

Hyper-K\"ahler Fourfolds Fibered by Elliptic Products [PDF]
Épijournal de Géométrie Algébrique, 2018 Every fibration of a projective hyper-K\"ahler fourfold has fibers which are Abelian surfaces. In case the Abelian surface is a Jacobian of a genus two curve, these have been classified by Markushevich. We study those cases where the Abelian surface is a

Modification rule of monodromies in R_2-move
, 2012 An R_2-move is a homotopy of wrinkled fibrations which deforms images of indefinite fold singularities like Reidemeister move of type II. Variants of this move are contained in several important deformations of wrinkled fibrations, flip and slip for ...

ON THE DYNAMICAL DEGREES OF MEROMORPHIC MAPS PRESERVING A FIBRATION [PDF]
, 2011 Let f be a dominant meromorphic self-map on a compact Kahler manifold X which preserves a meromorphic fibration π : X → Y of X over a compact Kahler manifold Y.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.

The near-horizon geometry of supersymmetric rotating AdS4 black holes in M-theory
Journal of High Energy Physics, 2021 We classify the necessary and sufficient conditions to obtain the near-horizon geometry of extremal supersymmetric rotating black holes embedded in 11d supergravity which are associated to rotating M2-branes.

Spin(9) geometry of the octonionic Hopf fibration [PDF]
, 2012 We deal with Riemannian properties of the octonionic Hopf fibration S15 → S8, in terms of the structure given by its symmetry group Spin(9). In particular, we show that any vertical vector field has at least one zero, thus reproving the non-existence of ...
