Let $X\subset\mathbb{C}^m$ be an unbounded pure $k$-dimensional algebraic set. We define the tangent cones $C_{4, \infty}(X)$ and $C_{5,\infty}(X)$ of $X$ at infinity. We establish some of their properties and relations. We prove that $X$ must be an affine linear subspace of $\mathbb{C}^m$ provided that $C_{5, \infty}(X)$ has pure dimension $k$.

Calculation of symmetric and asymmetric vortex seperation on cones and tangent ogives based on discrete vortex models [PDF]
An inviscid discrete vortex model, with newly derived expressions for the tangential velocity imposed at the separation points, is used to investigate the symmetric and asymmetric vortex separation on cones and tangent ogives.

Algebraic aspects of tangent cones
Matemática Contemporânea, 1995 The present notes form an enlarged update of a series of lectures at the XII Escola de Álgebra, for a mixed audience of specialists whose expertise lied somewhere between commutative algebra and algebraic geometry. The notes do no claim complete originality.

Specialization to the tangent cone and Whitney Equisingularity
, 2011 Let (X,0) be a reduced, equidimensional germ of analytic singularity with reduced tangent cone (C_{X,0},0). We prove that the absence of exceptional cones is a necessary and sufficient condition for the smooth part \X^0 of the specialization to the ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, EarlyView.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

External Tangents and Closedness of Cone + Subspace
Journal of Mathematical Analysis and Applications, 1994 Let \(C\) be a closed cone in a separable normed space \(E\) and \(S\) be a finite-dimensional subspace of \(E\). The authors find a nice geometric criterion for the algebraic sum \(C+S\) to be closed.

Boost Approaches in Patients Undergoing Postoperative Radiotherapy
Journal of Surgical Oncology, EarlyView.ABSTRACT The use of breast conservation surgery for early‐stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes.

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation
Laser &Photonics Reviews, EarlyView.Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized
