N=2 SCFT and M Theory on AdS_4 x Q^{1,1,1} [PDF]

open access: yes, 1999
Coincident M2 branes at a conical singularity are related to M theory on AdS_4 x X_7 for an appropriate 7 dimensional Sasaki-Einstein manifold X_7. For X_7=Q^{1,1,1}=(SU(2) x SU(2) x SU(2))/(U(1) x U(1)) which was found sometime ago, the infrared limit ...

Molecular and clinical features of a Japanese medulloblastoma cohort: Subgroup‐specific prognostic stratification using economical/accessible diagnostic methods

open access: yesBrain Pathology, EarlyView.
This study characterizes the molecular subgroup–specific features of a nationwide Japanese cohort comprising 242 medulloblastomas (MBs). Furthermore, we introduce SEE‐6‐CNA, a simple, cost‐effective, and FFPE‐compatible molecular test that is applicable to routine pathology samples and serves as a surrogate for risk stratification in non‐WNT/non‐SHH ...

A Nationwide Central Diagnosis for Pediatric CNS Tumors in Japan: The JCCG Brain Tumor and Pathology Committees

open access: yesCancer Science, EarlyView.
In this report, we present the results of a nationwide initiative launched by the Japan Children's Cancer Group to provide integrated diagnoses for pediatric central nervous system (CNS) tumors, incorporating central pathological review and molecular profiling.

Totally Contact Umbilical Radical Transversal Lightlike Submanifolds Of An Almost Contact Manifold With B-Metric

open access: yes, 2017
In the present paper, we study the geometry of totally contact umbilical radical transversal lightlike submanifolds and totally contact umbilical CR- submanifold of an indenite Sasaki-like almost contact manifold with B-metric.

Sasaki versus Kähler groups [PDF]

open access: yes
We study fundamental groups of compact Sasaki manifolds and show that compared to Kähler groups, they exhibit rather different behaviour. This class of groups is not closed under taking direct products, and there is often an upper bound on the dimension

Manifold-like Matchbox Manifolds

open access: yes, 2019
A matchbox manifold is a generalized lamination, which is a continuum whose arccomponents define the leaves of a foliation of the space. The main result of this paper implies that a matchbox manifold which is manifold-like must be homeomorphic to a weak ...

Rice EMF3 Alleles Adjust Flower Opening Time to Enhance the Seed Setting Rate Under High Temperature Stress

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT To safeguard global food security against rapid population growth and a warming world, the effective genetic improvement of cereals is imperative. Flower opening time (FOT) critically affects the seed setting rate. In this study, we identified a gene, EARLY‐MORNING FLOWERING 3 (EMF3), in which single‐nucleotide substitutions strongly modulate ...

GEODESICITY AND ISOCLINITY PROPERTIES FOR THE TANGENT BUNDLE OF THE HEISENBERG MANIFOLD WITH SASAKI METRIC

open access: yes, 2012
We prove that the horizontal and vertical distributions of the tangent bundle with the Sasaki metric are isocline, the distributions given by the kernels of the horizontal and vertical lifts of the contact form ω on the Heisenberg manifold (H_3, g) to ...

Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

The Einstein–Hilbert Functional and the Sasaki–Futaki Invariant

open access: yes, 2017
International audienceWe show that the Einstein–Hilbert functional, as a functional on the space of Reeb vector fields, detects the vanishing Sasaki–Futaki invariant.
