-1 V bias 56 Gbps germanium waveguide p-i-n photodetector with silicon contacts

We demonstrate a silicon-contact-only 56 Gbps germanium waveguide photodetector operating at -1 V. The dark current is below 4 nA and the responsivity is 0.74 A/W at 1550 nm and 0.93 A/W at 1310 nm

On several problems in p-Bergman theory

In this paper, we first answer Chen-Zhang's problem on $p$-Bergman metric proposed in \cite{CZ22}. Second, we prove the off-diagonal p-Bergman kernel function $K_p(z,w)$ is H\"older continuous of order (1-$\varepsilon$) about the second component when $p>1$ for any $\varepsilon>0$, which improves the corresponding result of Chen-Zhang. Moreover, we prove the asymptotic behavior of the maximizer of $p$-Bergman kernel as $p\rightarrow 1^-$. Finally, we give a characterization of a class of holomorphic functions on $\mathbb{B}^1$ to be $L^p$-integrable.Comment: 10 page

A generalization of Ore's Theorem involving neighborhood unions

AbstractLet G be a graph of order n. Settling conjectures of Chen and Jackson, we prove the following generalization of Ore's Theorem: If G is 2-connected and |N(u)∪N(v)|⩾12n for every pair of nonadjacent vertices u,v, then either G is hamiltonian, or G is the Petersen graph, or G belongs to one of three families of exceptional graphs of connectivity 2

Addendum to Greater Snow Goose Article

Addendum to Greater Snow Goose Article In The Greater Snow Goose (Chen caerulescens atlanticus) in Nebraska by W. Ross Silcock, published in the Sept. 2004 issue of The Nebraska Bird Review, we failed to credit Randy Buettner of Grand Island, who made the original observation of the Greater Snow Goose and provided the specimen, which was obtained in Clay Co. and is shown in the photo, to William Lemburg
