The rapid development of high-speed railways (HSRs) puts forward high requirements on the corresponding communication system. Millimeter wave (mmWave) can be a promising solution due to its wide bandwidth, narrow beams, and rich spectrum resources. However, with large number antenna elements employed, energy-efficient solutions at mmWave frequencies are in great demand. Based HSR system multipl...

Aimed at the hyperspectral image (HSI) classification under condition of limited samples, this paper designs a joint spectral–spatial network based on metric meta-learning. First, in order to fully extract HSI fine features, squeeze and excitation (SE) attention mechanism is introduced into spectrum dimensional channel selectively useful features improve sensitivity information features. Second...

High-speed railway construction is extending to mountainous areas, and the harsh environment complex climate pose various risks slope construction. This seriously threatens human lives causes huge economic losses. The existing research results on safety of high cutting in HSRs are limited, a complete set risk assessment processes methods has not yet been formed. Therefore, this study, we aimed ...

Background: The landscape of systemic therapies for advanced non-melanoma skin cancers has been revolutionized by the advent immunotherapy. Cemiplimab is only immune checkpoint inhibitor (ICI) approved European Medicine Agency recurrent/metastatic cutaneous squamous cell carcinoma (cSCC). Its excellent efficacy outcomes are achieved due to its good tolerability profile. drug-related hypersensit...

In satellite-based remote sensing applications, the conversion of sensor recorded top-of-atmosphere reflectance to radiance, or vice-versa, is carried out using a reference spectral solar irradiance (SSI) dataset. The choice SSI spectrum has consistently changed over past four decades with increasing availability more accurate measurements greater coverage. Considerable differences (up 15% at c...

BACKGROUND A previous study has shown that shorter bevacizumab infusions (0.5 mg/kg/min) can be safely administered without increasing the risk of infusion-related hypersensitivity reactions (HSRs). However, the risk of proteinuria and hypertension in patients receiving shorter infusions of bevacizumab is undetermined. PATIENTS AND METHODS This was a multicenter, prospective, observational st...

Cisplatin was the first of the platinum drugs. Second-generation platinum derivative was carboplatin that its efficacy in the treatment of many malignancies is equal to cisplatin, and its toxicity profile is more favorable. Here we report on a 50-year-old woman with a history of cervix cancer who developed a severe hypersensitivity reaction (HSR) to carboplatin. She was admitted to the emergenc...

Plasmids bearing a mammalian replication initiation region (IR) and a nuclear matrix attachment region (MAR) are spontaneously amplified in transfected mammalian cells, and such amplification generates chromosomal homogeneously staining regions (HSRs) or extrachromosomal double minutes (DMs). This method provides a novel, efficient, and rapid way to establish cells that stably produce high leve...

Hydrogen exerts beneficial effects in disease animal models of ischemia-reperfusion injury as well as inflammatory and neurological disease. Additionally, molecular hydrogen is useful for various novel medical and therapeutic applications in the clinical setting. In the present study, the hydrogen concentration in rat blood and tissue was estimated. Wistar rats were orally administered hydrogen...
