Monitoring minuscule mechanical signals,both in magnitude and direction,is imperative in many application scenarios,e.g.,structural health monitoring and robotic sensing ***,the piezoelectric sensor struggles to satisfy the requirements for directional recognition due to the limited piezoelectric coefficient matrix,and achieving sensitivity for detecting micrometer-scale deformations is also ***,we develop a vector sensor composed of lead zirconate titanate-electronic grade glass fiber composite filaments with oriented arrangement,capable of detecting minute anisotropic *** as-prepared vector sensor can identify the deformation directions even when subjected to an unprecedented nominal strain of 0.06%,thereby enabling its utility in accurately discerning the 5μm-height wrinkles in thin films and in monitoring human pulse *** ultra-high sensitivity is attributed to the formation of porous ferroelectret and the efficient load transfer efficiency of continuous lead zirconate titanate ***,when integrated with machine learning techniques,the sensor’s capability to recognize multi-signals enables it to differentiate between 10 types of fine textures with 100%*** structural design in piezoelectric devices enables a more comprehensive perception of mechanical stimuli,offering a novel perspective for enhancing recognition accuracy.

Membranous nephropathy （MN） is the most common cause of nephrotic syndrome in *** renal biopsy is the gold standard for the disease diagnosis,but is invasive.M-type phospholipase A2 receptor （PLA2R） on human podocytes could serve as the target for podocytopathic antibodies （anti-PLA2R）.1 Patients with iMN （70%-80%） were found the circulating antibodies against PLA2R.1 And the podocyte-secreted angiopoietinlike-4 （Angptl4） could be another key role in nephrotic syndrome3.

Abstract Objective To examine UVB-induced responses in normal human keratinocytes （HaCaT） and epidermoid carcinoma cells （A431） at the cellular and molecular level, and investigated the protective effect of salidroside. Methods Cells irradiated by UVB at various dosage and their viability was assessed by MTT assays, cell cycle was analysed by flow cytometry. The expression of NF-KB, BCL-2, and CDK6 after 50 J/㎡ UVB irradiation were detected by RT-PCR and western blotting. Results Our results confirmed greater tolerance of A341 cells to UVB-induced damage such as cell viability and cell cycle arrest, which was accompanied by differential expression changes in NF-KB, BCL-2, and CDK6. UVB exposure resulted in HaCaT cells undergoing G1-S phase arrest. When treated with salidroside, HaCaT survival was significantly enhanced following exposure to UVB, suggesting great therapeutic potential for this compound. Conclusion Taken together, our study suggests that A431 respond differently to UVB than norma HaCaT cells, and supports a role for NF-KB, CDK6, and BCL-2 in UVB-induced cell G1-S phase arrest Furthermore, salidroside can effectively protect HaCaT from UVB irradiation.

Plasmonic nanoantennas provide unique opportunities for precise control of light–matter coupling in surface-enhanced infrared absorption(SEIRA)spectroscopy,but most of the resonant systems realized so far suffer from the obstacles of low sensitivity,narrow bandwidth,and asymmetric Fano resonance ***,we demonstrated an overcoupled resonator with a high plasmon-molecule coupling coefficient(μ)(OC-Hμresonator)by precisely controlling the radiation loss channel,the resonator-oscillator coupling channel,and the frequency detuning *** observed a strong dependence of the sensing performance on the coupling state,and demonstrated that OC-Hμresonator has excellent sensing properties of ultra-sensitive(7.25%nm^(−1)),ultra-broadband(3–10μm),and immune asymmetric Fano *** characteristics represent a breakthrough in SEIRA technology and lay the foundation for specific recognition of biomolecules,trace detection,and protein secondary structure analysis using a single array(array size is 100×100μm^(2)).In addition,with the assistance of machine learning,mixture classification,concentration prediction and spectral reconstruction were achieved with the highest accuracy of 100%.Finally,we demonstrated the potential of OC-Hμresonator for SARS-CoV-2 *** findings will promote the wider application of SEIRA technology,while providing new ideas for other enhanced spectroscopy technologies,quantum photonics and studying light–matter interactions.

在日本行政诉讼法中以"法律利益"作为撤销诉讼原告资格的标准,但由于"法律利益"概念的不确定性,在学说及判例中存在着法律上保护利益说与值得保护利益说两种解释方法的对立。为扩大原告资格的范围,并防止法官过度的自由裁量,2004年6月日本《行政事件诉讼法》修改时采用了两种学说的折衷方案,即为"法律利益"标准的判断设置了四项必须考虑的要素,由法官依据该四项考虑要素来判断是否具有"法律利益"。
