Enhance the Efficiency of Graphene-based THz Modulator by Optimizing the Brewster Angle

Xingyue Li, zhaohui zhang, Xiaoyan Zhao, Tianyao Zhang, Luqi Tao, Zhengyong Huang, Ying Li, Xianhao Wu, Lu Yin & Yuan Yuan
The gate-controllable electronical property of graphene provides a possibility of active tuning property for THz modulator. However, the common modulation technology which only depends on voltage cannot solve the problem of power consumption limitation in communication applications. Here, we demonstrated a Brewster angle-controlled graphene-based THz modulator, which could achieve a relatively high modulation depth with low voltage. First, we explored the complex relationships among the Brewster angles, reflection coefficients and the conductivities of graphene. Then,...

Hemin-incorporating DNA nanozyme enabling catalytic oxygenation and GSH depletion for enhanced photodynamic therapy and synergistic tumor ferroptosis

Xiaoxiong Xiao, Min Chen, Yuchen Zhang, Liang Li, Ying Peng, Junyu Li & Wenhu Zhou
Abstract Photodynamic therapy (PDT) has emerged as a promising tumor treatment method via light-triggered generation of reactive oxygen species (ROS) to kill tumor cells. However, the efficacy of PDT is usually restricted by several biological limitations, including hypoxia, excess glutathione (GSH) neutralization, as well as tumor resistance. To tackle these issues, herein we developed a new kind of DNA nanozyme to realize enhanced PDT and synergistic tumor ferroptosis. The DNA nanozyme was constructed via rolling...

Abstract Pseudomonas aeruginosa (P. aeruginosa) is a known bacterium that produces biofilms and causes severe infection. Furthermore, P. aeruginosa biofilms are extremely difficult to eradicate, leading to the development of chronic and antibiotic-resistant infections. Our previous study showed that a cathelicidin-related antimicrobial peptide (CRAMP) inhibits the formation of P. aeruginosa biofilms and markedly reduces the biomass of preformed biofilms, while the mechanism of eradicating bacterial biofilms remains elusive. Therefore, in this study, the potential mechanism...

Abstract Non-small cell lung cancer (NSCLC) is a heterogeneous disease, and its demarcation contributes to various therapeutic outcomes. However, a small subset of tumors shows different molecular features that are in contradiction with pathological classification. Unsupervised clustering was performed to subtype NSCLC using the transcriptome data from the TCGA database. Next, immune microenvironment features of lung adenocarcinoma (LUAD), lung squamous carcinoma (LUSC), and lung adenoid squamous carcinoma (LASC) were characterized. In addition, diagnostic biomarkers to...

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...

Real-time realistic computer-generated hologram with accurate depth precision and a large depth range

Chongli Zhong, Xinzhu Sang, Binbin Yan, Hui Li, Duo Chen & Xiujuan Qin
Holographic display is an ideal technology for near-eye display to realize virtual and augmented reality applications, because it can provide all depth perception cues. However, depth performance is sacrificed by exiting computer-generated hologram (CGH) methods for real-time calculation. In this paper, volume representation and improved ray tracing algorithm are proposed for real-time CGH generation with enhanced depth performance. Using the single fast Fourier transform (S-FFT) method, the volume representation enables a low calculation burden and...

Label-Free Measurement of Wall Shear Stress in Brain Venule and Arteriole Using Dual-Wavelength Third-Harmonic-Generation Line-Scanning Imaging

Hui Cheng, Xinlin Chen, Zhong jincheng, Jia Li, Ping Qiu & Ke Wang
Wall shear stress (WSS) is of fundamental physiological and pathological significance. Current measurement technologies suffer from poor spatial resolution, or cannot measure instantaneous values in a label-free manner. Here we demonstrate dual-wavelength third-harmonic-generation (THG) line-scanning imaging, for instantaneous wall shear rate and WSS measurement in vivo. We used soliton self-frequency shift to generate dual-wavelength femtosecond pulses. Simultaneous acquisition of dual-wavelength THG line-scanning signals extract blood flow velocities at adjacent radial positions for instantaneous wall shear...

Supplementary material from \"Sensory evolution in a cavefish radiation: patterns of neuromast distribution and associated behaviour in Sinocyclocheilus (Cypriniformes: Cyprinidae)\"

Bing Chen, Tingru Mao, Yewei Liu, Wenzhang Dai, Xianglin Li, Amrapali P. Rajput, Marcio R. Pie, Jian Yang, Joshua B. Gross & Madhava Meegaskumbura
The genus Sinocyclocheilus, comprises a large radiation of freshwater cavefishes, are well known for their presence of regressive features (e.g. variable eye reduction). Fewer constructive features are known, such as the expansion of the lateral line system (LLS), which is involved in detecting water movements. The precise relationship between LLS expansion and cave adaptation is not well understood. Here, we examine morphology and LLS-mediated behaviour in Sinocyclocheilus species characterized by broad variation in eye size,...

Yongliang Li, Pai Qin, Aolong Sun, Wenjun Xiao, Fenglin Chen, Yang He, Keyao Yu, You Li, Meng Zhang & Xinhong Guo
Abstract Background RING (Really Interesting New Gene) zinc finger (RING-zf) proteins belong to an important subclass of zinc fingers superfamily, which play versatile roles during various developmental stages and in abiotic stress responses. Based on the conserved cysteine and histidine residues, the RING-zf domains are classified into RING-HC (C3HC4), RING-H2 (C3H2C3), RING-v, RING-D, RING-S/T, RING-G, and RING-C2. However, little is known about the function of the RING-zfs of wheat. Results In this study, 129 (93.5%)...

Chi Liu, Xiaoli Liu, Xiaoteng Ma, Yujing Cheng, Yan Sun, Dai Zhang, Qi Zhao & Yujie Zhou
Abstract Background Measurement of estimated glucose disposal rate (eGDR) has been demonstrated to be an indicator of insulin resistance (IR) and a risk sign for long-term outcomes in those with ischemic heart disease and type 2 diabetes mellitus (T2DM) having coronary artery bypass grafting (CABG). After elective percutaneous coronary intervention (PCI), the usefulness of eGDR for prognosis in those with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and non-diabetes is yet unknown. Methods 1510 NSTE-ACS patients...

LPAR5 confers radioresistance to cancer cells associated with EMT activation via the ERK/Snail pathway

Xiao-Ya Sun, Hao-Zheng Li, Da-Fei Xie, Shan-Shan Gao, Xin Huang, Hua Guan, Chen-Jun Bai & Ping-Kun Zhou
Abstract Background Epithelial-to-mesenchymal transition (EMT) is a critical event contributing to more aggressive phenotypes in cancer cells. EMT is frequently activated in radiation-targeted cells during the course of radiotherapy, which often endows cancers with acquired radioresistance. However, the upstream molecules driving the signaling pathways of radiation-induced EMT have not been fully delineated. Methods In this study, RNA-seq-based transcriptome analysis was performed to identify the early responsive genes of HeLa cells to γ-ray irradiation. EMT-associated genes...
