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

Partial wave analysis of J/ψ→γϕϕ
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 aExpand

Type-II nodal loops: Theory and material realization
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 typeExpand

Landscape of infiltrating B cells and their clinical significance in human hepatocellular carcinoma
ABSTRACT As a major cellular component in tumor microenvironment, the distribution, frequency, and prognostic significance of infiltrating B cell subsets in hepatocellular carcinoma (HCC) remainExpand

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 theExpand

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

Nodal loop and nodal surface states in the Ti 3 Al family of materials
Topological metals and semimetals are new states of matter which are attracting great interest in current research. Here, based on first-principles calculations and symmetry analysis, we propose thatExpand

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

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 concaveExpand
