On Bott-Chern cohomology of compact complex surfaces [PDF]
Annali Di Matematica Pura Ed Applicata, 2014 We study Bott-Chern cohomology on compact complex non-K\"ahler surfaces. In particular, we compute such a cohomology for compact complex surfaces in class $\text{VII}$ and for compact complex surfaces diffeomorphic to ...

Strong and Agile Wall-Climbing Robots Capable of Traversing Obstacles via Anisotropic Acoustic Adhesion [PDF]
ResearchSmall inspection robots are highly desirable for inspecting complex machinery and detecting damage in confined spaces. However, common climbing robots that rely on vacuum suction or bioinspired dry adhesion often suffer from bulky sizes or slow ...

Optimized spectral indices for global vegetation and water mapping using Sentinel-2 [PDF]
Scientific ReportsReliable mapping of vegetation and surface water from satellite imagery remains challenging, as common spectral indices can saturate at high biomass, show limited sensitivity across ecosystems, and confuse targets with soil, shadows, or built-up surfaces.

A gluing construction of projective K3 surfaces [PDF]
Épijournal de Géométrie Algébrique, 2022 We construct a non-Kummer projective K3 surface $X$ which admits compact Levi-flats by holomorphically patching two open complex surfaces obtained as the complements of tubular neighborhoods of elliptic curves embedded in blow-ups of the projective plane

Complex Manifolds, 2023 Let XX be a simple normal crossing (SNC) compact complex surface with trivial canonical bundle which includes triple intersections. We prove that if XX is dd-semistable, then there exists a family of smoothings in a differential geometric sense. This can

Riemann-Roch theorem and Kodaira-Serre duality
Annals of the West University of Timisoara: Mathematics and Computer Science, 2022 The Riemann-Roch theorem is of utmost importance and a vital tool to the fields of complex analysis and algebraic geometry, specifically in the algebraic geometric theory of compact Riemann surfaces.

Fundamental Studies of Rapidly Fabricated On-Chip Passive Micromixer for Modular Microfluidics
Micromachines, 2021 Micromixers play an important role in many modular microfluidics. Complex on-chip mixing units and smooth channel surfaces ablated by lasers on polymers are well-known problems for microfluidic chip fabricating techniques.

A New Proof of a Conjecture on Nonpositive Ricci Curved Compact Kähler–Einstein Surfaces
Mathematics, 2018 In an earlier paper, we gave a proof of the conjecture of the pinching of the bisectional curvature mentioned in those two papers of Hong et al. of 1988 and 2011. Moreover, we proved that any compact Kähler–Einstein surface M is a quotient of the complex
