Coexistence of four-band nodal rings and triply degenerate nodal points in centrosymmetric metal diborides

- X. Zhang, Z. Yu, Xian-Lei Sheng, H. Yang, S. A. Yang
- Physics
- 12 April 2017

Topological metals with protected band-crossing points have been attracting great interest. Here we report novel topological band features in a family of metal diboride materials. Using first-… Expand

- 1 May 2008

Abstract Using 5.8 × 10 7 J / ψ events collected in the BESII detector, the radiative decay J / ψ → γ ϕ ϕ → γ K + K − K S 0 K L 0 is studied. The ϕϕ invariant mass distribution exhibits a… Expand

Type-II nodal loops: Theory and material realization

- Si Li, Z. Yu, +5 authors S. A. Yang
- Physics
- 5 May 2017

Nodal loop appears when two bands, typically one electron-like and one hole-like, are crossing each other linearly along a one-dimensional manifold in the reciprocal space. Here we propose a new type… Expand

Analytical Expression of the Swept Surface of a Rotary Cutter Using the Envelope Theory of Sphere Congruence

Based on the observation that many surfaces of revolution can be treated as a canal surface, i.e., the envelope surface of a one-parameter family of spheres, the analytical expressions of the… Expand

Lupus-associated atypical memory B cells are mTORC1-hyperactivated and functionally dysregulated

- Chunmei Wu, Q. Fu, +15 authors X. Zhang
- Medicine
- Annals of the rheumatic diseases
- 29 May 2019

Objectives A population of atypical memory B cells (AtMs) are greatly expanded in patients with active lupus, but their generation and pathophysiological roles are poorly defined. The aim of this… Expand

Kinematic generation of ruled surface based on rational motion of point-line

- X. Zhang, L. Zhu, H. Ding, Youlun Xiong
- Mathematics
- 2012

This paper studies representation of rigid combination of a directed line and a reference point on it (here referred to as a “point-line”) using dual quaternions. The geometric problem of rational… Expand

The Geometrical Convexity and Concavity of Integral for Convex and Concave Functions

Suppose that [a, b] ⊆ (0,∞), f : [a, b] → (0,∞) is a function. In this paper, the following two results are proved: (1)Both g(x) = ∫ b x f(t)dt and h(x) = ∫ x a f(t)dt are geometrically concave… Expand
