Cancer Reports, EarlyView., 2023 Abstract Background A methodology to assess the immune microenvironment (IME) of non‐small cell lung cancer (NSCLC) has not been established, and the prognostic impact of IME factors is not yet clear. Aims This study aimed to assess the IME factors and evaluate their prognostic values. Methods and Results We assessed CD8+ tumor‐infiltrating lymphocyte (

Curvature estimates for submanifolds immersed into horoballs and horocylinders [PDF]
, 2015 We prove mean and sectional curvature estimates for submanifolds confined into either a horocylinder of N × L or a horoball of N , where N is a Cartan–Hadamard manifold with pinched curvature.

On homogeneous closed gradient Laplacian solitons and the modified conformal Hessian [PDF]
, 2023 Laplacian solitons are self-similar solutions to a geometric flow of $G_2$-structures $\varphi \in \Omega^3(M)$ on smooth $7$-manifolds $M$ called the Laplacian flow. Recently, Laplacian solitons on homogeneous spaces have received increased interest and

Lipschitz continuity and Bochner-Eells-Sampson inequality for harmonic maps from RCD(K,N) spaces to CAT(0) spaces [PDF]
, 2023 We establish Lipschitz regularity of harmonic maps from RCD(K, N) metric measure spaces with lower Ricci curvature bounds and dimension upper bounds in synthetic sense with values into CAT(0) metric spaces with non-positive sectional curvature. Under the

Second Variation Formula and Stability of Exponentially Subelliptic Harmonic Maps [PDF]
, 2020 We study the stability of exponentially subelliptic harmonic (e.s.h.) maps from a Carnot-Carathéodory complete strictly pseudoconvex pseudohermitian manifold $(M, theta )$ into a Riemannian manifold $(N, h)$. E.s.h. maps are $C^infty$ solutions $phi

ON THE GEOMETRY OF NEWTON OPERATORS [PDF]
, 2012 We studied the geometry of hypersurfaces of complete constant higher order mean curvature, both in the Riemannian and in the Lorentzian setting. In particular, in the Riemannian setting, we focused on uniqueness results for hypersurfaces in warped ...

Proximal point algorithm with Schur decomposition on the cone of symmetric semidefinite positive matrices [PDF]
, 2009 In this work, we propose a proximal algorithm for unconstrained optimization on the cone of symmetric semidefinite positive matrices. It appears to be the first in the proximal class on the set of methods that convert a Symmetric Definite Positive ...

Abundant Superintegrable Systems and Hessian Structures [PDF]
We show that a large class of non-degenerate second-order (maximally) superintegrable systems gives rise to Hessian structures, which admit natural (Hessian) coordinates adapted to the superintegrable system.

Basic Geometric Structures on Manifolds [PDF]
, 2017 In this chapter, we give brief information about geometric structures which will be used in the following chapters. In addition to the basic concepts, some geometric notions such as symmetry conditions, parallelity conditions, new product structures on ...

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...
