Manipulating electromagnetic waves in a cavity-waveguide system with nontrivial and trivial modes

Jiong Xu, XiaoFei Zang, Xudong Zhan, Kun Liu & Yiming Zhu
The coupled cavity-waveguide approach provides a flexible platform to design integrated photonic devices that are widely applied in optical communications and information processing. Topological photonic crystals that can excite the nontrivial edge state (ES) and corner state (CS), have unprecedented capability in manipulating electromagnetic (EM) waves, leading to a variety of unusual functionalities that are impossible to achieve with conventional cavity-waveguide systems. In this paper, two-dimensional photonic crystals consisting of a topological ES waveguide, a...

Mid-infrared Nb₄N₃-based superconducting nanowire single photon detectors for wavelengths up to 10 μm

Yiming Pan, Hui Zhou, XINGYU ZHANG, Huiqin Yu, Lu Zhang, Mengting Si, Hao Li, Lixing YOU & Zhen Wang
Mid-infrared (MIR) single-photon detection is emerging as an important technology for various applications. Superconducting nanowire single photon detectors (SNSPDs) fabricated with superconducting films with energy gaps of a few meV are natural broadband single-photon detectors. Recently, extending SNSPDs’ operation wavelengths into the MIR region is highly attractive. γ-Nb₄N₃ has a reduced N content and lower energy gap than the commonly used δ-NbN, making SNSPDs based on γ-Nb₄N₃ film more sensitive to low energy photons. We...

Penalized Spline-Involved Tree-based (PenSIT) Learning for estimating an optimal dynamic treatment regime using observational data

Kelly A Speth, Michael R Elliott, Juan L Marquez & Lu Wang
Dynamic treatment regimes are a set of time-adaptive decision rules that can be used to personalize treatment across multiple stages of care. Grounded in causal inference methods, dynamic treatment regimes identify variables that differentiate the treatment effect and may be used to tailor treatments across individuals based on the patient’s own characteristics – thereby representing an important step toward personalized medicine. In this manuscript we introduce Penalized Spline-Involved Tree-based Learning, which seeks to improve upon...

Combination of oral STING agonist MSA-2 and anti-TGF-β/PD-L1 bispecific antibody YM101: a novel immune cocktail therapy for non-inflamed tumors

Ming Yi, Mengke Niu, Yuze Wu, Hong Ge, Dechao Jiao, Shuangli Zhu, Jing Zhang, Yongxiang Yan, Pengfei Zhou, Qian Chu & Kongming Wu
Abstract Background Non-inflamed tumors, including immune-excluded and immune-desert tumors, are commonly resistant to anti-PD-1/PD-L1 (α-PD-1/PD-L1) therapy. Our previous study reported the potent antitumor activity of anti-TGF-β/PD-L1 bispecific antibody YM101 in immune-excluded tumors. However, YM101 had limited antitumor activity in immune-desert models. MSA-2 is a novel oral stimulator of interferon genes (STING) agonist, which activates the innate immune system and may synergize with YM101 in overcoming immunotherapy resistance. Methods The dose-dependent effect of MSA-2 on STING...

Self-supervised next view prediction for limited-angle optical projection tomography

Hao Zhang, binbing liu & Peng Fei
Optical projection tomography captures 2-D projections of rotating biological samples and computationally reconstructs 3-D structures from these projections, where hundreds of views with an angular range of π radian is desired for a reliable reconstruction. Limited-angle tomography tries to recover the structures of the sample using fewer angles of projections. However, the result is far from satisfactory due to the missing of wedge information. Here we introduce a novel view prediction technique, which is able...

A general method for calculating power for GEE analysis of complete and incomplete stepped wedge cluster randomized trials

Ying Zhang, John S Preisser, Elizabeth L Turner, Paul J Rathouz, Mark Toles & Fan Li
Stepped wedge designs have uni-directional crossovers at randomly assigned time points (steps) where clusters switch from control to intervention condition. Incomplete stepped wedge designs are increasingly used in cluster randomized trials of health care interventions and have periods without data collection due to logistical, resource and patient-centered considerations. The development of sample size formulae for stepped wedge trials has primarily focused on complete designs and continuous responses. Addressing this gap, a general, fast, non-simulation based...
