Unveiling the mechanism of dynamic transverse mode instability mitigation through static mode degradation: a study in the two-mode fiber lasers.

Dynamic transverse mode instability (TMI) has become one of the primary limitations for power scaling of high-power fiber lasers. Experimental evidence has shown that static mode degradation can suppress the dynamic TMI effect. This study reveals the physical mechanisms behind the mitigation of dynamic TMI in two-mode fiber lasers through static mode degradation.

Elevating the TMI threshold by incorporating QCW pumping in a high-power CW fiber oscillator.

Transverse mode instability (TMI) significantly limits the power scaling of ytterbium-doped fiber lasers. In this Letter, what we believe to be a novel TMI mitigation strategy is proposed and demonstrated in a bidirectional output fiber laser. On the basis of the continuous wave (CW) pump, integrating a quasi-continuous wave (QCW) pump can effectively improve the TMI threshold of the system.

Piezoelectric-Augmented Thermoelectric Ionogels for Self-Powered Multimodal Medical Sensors.

A paradigm ionogel consisting of ionic liquid (IL) and PVDF-HFP composites is made, which inherently possesses dual-function ionic thermoelectric (iTE) and piezoelectric (PE) attributes.

By harnessing these multifaceted features, fully self-powered, multimodal sensors demonstrate their superior energy conversion capabilities, which possessed minimum sensitivities of 0.

In situ self-reassembling nanosystem enhances PD-L1 blockade for cancer immunotherapy.

Although immune checkpoint inhibitors (ICIs) have made great progress in cancer treatment, their off-tumor distribution, low affinity of traditional ICIs and insufficient T cells infiltration at tumor site limit immunotherapeutic efficacy. Herein, we engineer a highly specific and effective PD-L1 inhibitor (PEC) that modulates the level of binding sites with PD-L1. Specifically, PEC is a hybrid system composed of E.

Association of CD8TILs co-expressing granzyme A and interferon-γ with colon cancer cells in the tumor microenvironment.

CD8T cells secreting granzyme A (GZMA) can induce pyroptosis in tumor cells by effectively cleaving gasdermin B (GSDMB), which is stimulated by interferon-γ (IFN-γ). However, the interaction between GZMA-expressing CD8T cells and GSDMB-expressing tumor cells in colon cancer remains poorly understood. Our research employed multi-color immunohistochemistry (mIHC) staining and integrated clinical data to explore the spatial distribution and clinical relevance of GZMA- and IFN-γ-expressing CD8 tumor-infiltrating lymphocytes (TILs), as well as GSDMB-expressing CK cells, within the tumor microenvironment (TME) of human colon cancer samples.

Ovarian cancer is a malignant tumor originating from the ovary, characterized by its high mortality rate and propensity for recurrence. In some patients, especially those with recurrent cancer, conventional treatments such as surgical resection or standard chemotherapy yield suboptimal results. Consequently, there is an urgent need for novel anti-cancer therapeutic strategies.

Revolutionizing tumor immunotherapy: unleashing the power of progenitor exhausted T cells.

In exploring persistent infections and malignancies, a distinctive subgroup of CD8 T cells, progenitor exhausted CD8 T (Tpex) cells, has been identified. These Tpex cells are notable for their remarkable self-renewal and rapid proliferation abilities. Recent strides in immunotherapy have demonstrated that Tpex cells expand and differentiate into responsive exhausted CD8 T cells, thus underscoring their critical role in the immunotherapeutic retort.
