Engineering Reports, Volume 5, Issue 1, January 2023., 2023 (1) The study found that the pupil area change rate, heart beat change rate and eyelid closure have good consistency for characterizing the driver's load. (2) In mountainous road, the driving load is different under different alignment conditions. The driving load is the largest when turning left, the second when turning right, and the smallest when ...

Cohomology of moduli spaces of Del Pezzo surfaces
Mathematische Nachrichten, Volume 296, Issue 1, Page 80-101, January 2023., 2023 Abstract We compute the rational Betti cohomology groups of the coarse moduli spaces of geometrically marked Del Pezzo surfaces of degree 3 and 4 as representations of the Weyl groups of the corresponding root systems. The proof uses a blend of methods from point counting over finite fields and techniques from arrangement complements.

Studies in Applied Mathematics, Volume 150, Issue 1, Page 254-276, January 2023., 2023 Abstract We consider the highly oscillatory integral F(w):=∫−∞∞eiw(tK+2+eiθtp)g(t)dt$F(w):=\int _{-\infty }^\infty e^{iw(t^{K+2}+e^{i\theta }t^p)}g(t)dt$ for large positive values of w, −π<θ≤π$-\pi <\theta \le \pi$, K and p positive integers with 1≤p≤K$1\le p\le K$, and g(t)$g(t)$ an entire function.

Hyperelliptic classes are rigid and extremal in genus two [PDF]
Épijournal de Géométrie Algébrique, 2020 We show that the class of the locus of hyperelliptic curves with $\ell$ marked Weierstrass points, $m$ marked conjugate pairs of points, and $n$ free marked points is rigid and extremal in the cone of effective codimension-($\ell + m$) classes on ...

Conformal surface defects in Maxwell theory are trivial
Journal of High Energy Physics, 2022 We consider a free Maxwell field in four dimensions in the presence of a codimension two defect. Reflection positive, codimension two defects which preserve conformal symmetry in this context are very limited.

Embedding codimension of the space of arcs
Forum of Mathematics, Pi, 2022 We introduce a notion of embedding codimension of an arbitrary local ring, establish some general properties and study in detail the case of arc spaces of schemes of finite type over a field.

Quantum dynamics in high codimension tilings: from quasiperiodicity to disorder [PDF]
Phys. Rev. B 68, 172202 (2003), 2003 We analyze the spreading of wavepackets in two-dimensional quasiperiodic and random tilings as a function of their codimension, i.e. of their topological complexity. In the quasiperiodic case, we show that the diffusion exponent that characterizes the propagation decreases when the codimension increases and goes to 1/2 in the high codimension limit. By
