Dynamic Stability and Control Authority Blending in Lift-Plus-Cruise eVTOL Transition Flight

Dynamics
Lift-plus-cruise electric vertical takeoff and landing (eVTOL) aircraft exhibit complex stability characteristics during transition flight, when rotor-borne and wing-borne regimes coexist.

The Lifting Problem is NP Complete

, 2016
Let $M$ be a 3-manifold. Every knotted (embedded) surface in $M \times \R$ can be moved via an ambient isotopy in such a way that its projection into $M$ is a generic surface. A surface is generic if every point on it is either a regular, double or triple value - the transversal intersection of 1, 2 or 3 embedded surface sheets, or a "branch value ...

Affine transformations of the tangent bundle with a complete lift connection over a manifold with a linear connection of special type

Дифференциальная геометрия многообразий фигур, 2018
In this paper we obtain exact upper bounds for the dimensions of Lie al­ge­bras of infinitesimal affine transformations in tangent bundles with a comp­lete lift connection in the case when the base space is a manifold equipped with a non-projective ...

Lifting Dual Connections with the Riemann Extension

Mathematics, 2020
Let (M,g) be a Riemannian manifold equipped with a pair of dual connections (∇,∇*). Such a structure is known as a statistical manifold since it was defined in the context of information geometry.

The Role of Chemotherapy in Pediatric Myoepithelial Carcinoma: A Systematic Review of the Literature

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Myoepithelial carcinoma (MEC) in pediatric patients is a rare and aggressive malignancy characterized by heterogeneous morphology and variable molecular features. The optimal role of chemotherapy remains unclear. We conducted a systematic review according to PRISMA 2020 guidelines to evaluate chemotherapy in pediatric and young‐adult patients ...

Assessment of LIFT (ligation of the intersphincteric fistula tract) technique in patients with perianal transsphincteric fistulas

Journal of Coloproctology, 2014
Perianal fistulas are a relatively common condition in Proctology offices, ranging from simple cases with easily palpable superficial tracts to complex problems with deep tracts across significant portions of the anal sphincter, which section can lead to

Occurrence of Extramedullary Relapses in Pediatric Acute Lymphoblastic Leukemia After Treatment With Blinatumomab

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We report a retrospective single‐center analysis of pediatric patients with relapsed or refractory B‐cell precursor acute lymphoblastic leukemia focusing on relapses outside of the typical locations, bone marrow, central nervous system, or testes.
