Open AccessTopologically enhanced nonlinear optical response of graphene nanoribbon heterojunctions
We study the nonlinear optical properties of heterojunctions made of graphene nanoribbons (GNRs) consisting of two segments with either the same or different topological properties. By utilizing a quantum mech...

Symmetry breaking and restoration of symmetric solitons in partially parity-time-symmetric potentials
We address the symmetry-breaking bifurcation of optical solitons in cubic–quintic media with an imprinted partially parity-time-symmetric potential. An increase in soliton power leads to symmetry breaking, whi...

Clinicopathological Outcomes and Prognosis of Elderly Patients (≥ 65 Years) with Gastric Gastrointestinal Stromal Tumors (GISTs) Undergoing Curative-Intent Resection: a Multicenter Data Review
The most common site of gastrointestinal stromal tumors (GISTs) is the stomach, and gastric GISTs (gGISTs) occur most often in elderly patients. However, the clinicopathological features, treatment patterns, a...

Open AccessStudy on safety of laparoscopic total gastrectomy for clinical stage I gastric cancer: the protocol of the CLASS02–01 multicenter randomized controlled clinical trial
The safety of laparoscopic total gastrectomy (LTG) for the treatment of gastric cancer remains lack of clinical evidence. The Chinese Laparoscopic Gastrointestinal Surgery Study (CLASS) Group recently launched...

Open AccessTunable band-gap structure and gap solitons in the generalized Gross-Pitaevskii equation with a periodic potential
The tunable band-gap structure is fundamentally important in the dynamics of both linear and nonlinear modes trapped in a lattice because Bloch modes can only exist in the bands of the periodic system and nonl...

Open AccessBeam propagation management in a fractional Schrödinger equation
Generalization of Fractional Schrödinger equation (FSE) into optics is fundamentally important, since optics usually provides a fertile ground where FSE-related phenomena can be effectively observed. Beam prop...
