Therapeutic strategies in vascular cognitive impairment: A systematic review and meta-analysis. [PDF]
Alzheimers DementAbstract INTRODUCTION Vascular cognitive impairment (VCI) is a common, heterogeneous condition, currently lacking approved treatments. METHODS We reviewed therapeutic strategies tested in VCI and meta‐analyzed efficacy data for eligible interventions to assess whether previously tested treatments warranted reconsideration.

Fractional branes and wrapped branes [PDF]
Journal of High Energy Physics, 1998 We discuss the ``fractional D-branes'' which arise in orbifold resolution. We argue that they arise as subsectors of the Coulomb branch of the quiver gauge theory used to describe both string theory D-brane and Matrix theory on an orbifold, and thus must form part of the full physical Hilbert space.

T-branes as branes within branes [PDF]
Journal of High Energy Physics, 2015 Bound states of 7-branes known as 'T-branes' have properties that defy usual geometric intuition. For instance, the gauge group of n coincident branes may not be U(n). More surprisingly, matter may show up at unexpected loci, such as points. By analyzing T-branes of perturbative type IIB string theory in the tachyon condensation picture we gain the ...

Brane-intersection dynamics from branes in brane backgrounds [PDF]
Physics Letters B, 1998 We derive the dynamics of M-brane intersections from the worldvolume action of one brane in the background supergravity solution of another one. In this way we obtain an effective action for the self-dual string boundary of an M2-brane in an M5-brane, and show that the dynamics of the 3-brane intersection of two M5-branes is described by a Dirac-Born ...

Accelerating branes and brane temperature [PDF]
Classical and Quantum Gravity, 2008 We define the local acceleration and jerk of a relativistic brane in an ambient spacetime, and construct from them a dimensionless parameter lambda that must be small for an interpretation of brane acceleration as local Unruh temperature. As examples, we discuss (i) open rotating branes, for which lambda>1 (ii) closed spherical branes expanding in ...

Brane-antibrane democracy [PDF]
Physical Review D, 1996 We suggest a duality invariant formula for the entropy and temperature of non-extreme black holes in supersymmetric string theory. The entropy is given in terms of the duality invariant parameter of the deviation from extremality and 56 SU(8) covariant central charges.

Nuclear Physics B, 2004 We use the `branes within branes' approach to study the appearance of stable $ (p-2)-branes and unstable (p-1)-branes in type II string theory from p-brane--p-antibrane pairs.Our goal is to describe the emergence of these lower dimensional branes from brane-antibrane pairs in string theory using a tractable gauge theory language.
