Journal of High Energy Physics, 2023 Microstrata are the non-extremal analogues of superstrata: they are smooth, non-extremal (non-BPS) solitonic solutions to IIB supergravity whose deep-throat limits approximate black holes.

Conifold Transitions in M-theory on Calabi-Yau Fourfolds with Background Fluxes [PDF]
, 2012 We consider topology changing transitions for M-theory compactifications on Calabi-Yau fourfolds with background G-flux. The local geometry of the transition is generically a genus g curve of conifold singularities, which engineers a 3d gauge theory with

D-brane Approach to Black Hole Quantum Mechanics [PDF]
, 1996 Strominger and Vafa have used D-brane technology to identify and precisely count the degenerate quantum states responsible for the entropy of certain extremal, BPS-saturated black holes. Here we give a Type-II D-brane description of a class of extremal {\

Large diffeomorphisms and accidental symmetry of the extremal horizon
Journal of High Energy Physics, 2022 We uncover a symmetry of the linear Einstein equations near extremal horizons. Specifically, acting with a spherically symmetric linearized diffeomorphism on the perturbative solutions to the Einstein-Maxwell equations in the Bertotti-Robinson background,

Extremal maps of the universal hyperbolic solenoid [PDF]
, 2006 We show that the set of points in the Teichmuller space of the universal hyperbolic solenoid which do not have a Teichmuller extremal representative is generic (that is, its complement is the set of the first kind in the sense of Baire). This is in sharp

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

New branches of non-supersymmetric attractors in N=2 supergravity
Physics Letters B, 2017 In this paper we analyse non-supersymmetric single centred extremal black hole solutions in N=2 supergravity theory coupled to n vector multiplets with purely cubic pre-potential in four dimensions.

Open-Set Specific Emitter Identification Based on Prototypical Networks and Extreme Value Theory
Applied Sciences, 2023 Much research has focused on classification within a closed set of emitters, while emitters outside this closed set are misclassified. This paper proposes an open-set recognition model based on prototypical networks and extreme value theory to solve the problem of specific emitter identification in open-set scenes and further improve the recognition ...
