Set-theoretic generators of rational space curves
, 2010 We show how to calculate three low degree set-theoretic generators (i.e., algebraic surfaces) for all rational space curves of low degree (degree ≤6) as well as for all higher degree rational space curves where at least one element of their μ-basis has ...

The degree of the variety of rational ruled surfaces and Gromov-Witten invariants [PDF]
Transactions of the American Mathematical Society, 2005 We compute the degree of the variety parametrizing rational ruled surfaces of degree d in the projective space by relating the problem to Gromov-Witten invariants and Quantum cohomology.

Advanced Optical Materials, EarlyView.This work aims to understand the origin of pattern deviation in PEDOT:Tos films formed via vapor phase polymerization on UV‐exposed oxidant. UV exposure induces formation of loosely bound water which diffuses and produces macroscopic structuring at increased block copolymer contents.

The Atiyah–Jones conjecture for rational surfaces
, 2008 We show that if the Atiyah–Jones conjecture holds for a surface X, then it also holds for the blow-up of X at a point. Since the conjecture is known to hold for P2 and for ruled surfaces, it follows that the conjecture is true for all rational ...

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals
Advanced Optical Materials, EarlyView.A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...

On Donaldson polynomials of rational ruled surfaces
Forum Mathematicum, 1996 Let \(\pi:X= \mathbb{F}_e\to\mathbb{P}^1\) be a rational ruled surface, where \(e\) is a nonnegative integer. Let \(f\) be a fibre of \(\pi\) and \(\sigma\) be a section to \(\pi\) with \(\sigma^2=-e\). Fix an integer \(c\). An ample divisor \((a\sigma+bf)\) is defined to be \(c\)-suitable if \(b/a> (c+e)/2\).

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe
Advanced Science, EarlyView.This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

Rank-3 Stable Bundles On Rational Ruled Surfaces
, 1996 . In this paper, we compare the moduli spaces of rank-3 vector bundles stable with respect to different ample divisors over rational ruled surfaces. We also discuss the irreducibility, unirationality, and rationality of these moduli spaces. Introduction.

Advanced Science, EarlyView.A biotin‐modified artificial insertion peptide functionalized three‐dimensional high‐curvature‐TiO2 nano‐interface was engineered in a microfluidic chip to improve the isolation efficiency of small extracellular vesicles (sEVs). This chip balanced affinity, releasability, and extendibility, enabling high‐throughput recovery of sEVs for downstream ...
