We experimentally demonstrate strong coupling between a one-dimensional (1D) single-atom array and high-finesse miniature cavity. The atom is obtained by loading single atoms into 1D optical tweezer with dimensions of 1×11. Therefore, deterministic number obtained, the determined imaging on CCD camera in real time. By precisely controlling position spacing high finesse Fabry-Perot cavity, all are strongly coupled to cavity simultaneously. vacuum Rabi splitting spectra discriminated for...
Abstract Fluids in subduction zones significantly influence element mobility, isotope fractionation, and mass transfer. However, unraveling the source, composition, redox state of fluids continental poses a significant challenge. This study focuses on granitic melt‐eclogite contact interface, along with adjacent granite eclogite from Sulu ultrahigh‐pressure metamorphic belt East China. The interface exhibits complex mineral assemblages, enriched rare earth elements (REEs), high field...
Landslide relic inventories serve as essential data for geological disaster investigations and risk assessments. Using a previously developed landslide inventory Minhe County, Qinghai Province, this study employs number density (LND) area percentage (LAP) to thoroughly investigate the spatial distribution characteristics of landslides in region. Utilizing GIS platform, we selected ten factors in-depth analysis, including elevation, slope aspect, gradient, relief degree land surface, distance...
Countries around the globe have implemented unprecedented measures to mitigate coronavirus disease 2019 (COVID-19) pandemic. We aim predict COVID-19 course and compare effectiveness of mitigation across countries inform policy decision making using a robust parsimonious survival-convolution model. account for transmission during pre-symptomatic incubation period use time-varying effective reproduction number (Rt ) reflect temporal trend change in response public health intervention. estimate...
Abstract LHRH receptor, is over-expressed in a variety of human tumors and, potential binding site for targeted metastatic prostate cancer therapy. The objectives our study were to synthesize bioconjugate the analog [DLys 6 ]-LHRH and anti-tumor agent methotrexate test hypothesis that ]-LHRH-MTX targets inhibits cell growth vitro vivo . results studies, showed both MTX displayed superior cytotoxicity against cells concentration-dependent manners, with IC 50 concentrations PC-3 of, 1.02 ±...
ABSTRACT The upper reaches of the Yellow River, located at northeastern edge Qinghai‐Tibet Plateau in China, are characterized by intense tectonic activity and widespread landslide geomorphology. Creating a detailed objective map geomorphology this region is crucial for understanding development landslides. However, availability high‐quality inventories area limited, hindering comprehensive scientific disaster prevention efforts. This study utilized multi‐temporal high‐resolution remote...
Transitional upper carboniferous Shanxi Formation coal-bearing strata in Qinshui Basin have been proven to be a set of mixed unconventional gas-bearing reservoirs forming multi-superimposed gas system that consists multiple independent fluid pressure systems vertically through the strata. An experimental protocol was designed compare pore networks high-rank coal, shale, and tight sandstone from using quantitative qualitative methods, including high-pressure mercury injection porosimetry...
Coronavirus disease 2019 (COVID-19) pandemic is an unprecedented global public health challenge. In the United States (US), state governments have implemented various non-pharmaceutical interventions (NPIs), such as physical distance closure (lockdown), stay-at-home order, mandatory facial mask in response to rapid spread of COVID-19. To evaluate effectiveness these NPIs, we propose a nested case-control design with propensity score weighting under quasi-experiment framework estimate average...
Countries around the globe have implemented unprecedented measures to mitigate coronavirus disease 2019 (COVID-19) pandemic. We aim predict COVID-19 course and compare effectiveness of mitigation across countries inform policy decision making. propose a robust parsimonious survival-convolution model for predicting key statistics epidemics (daily new cases). account transmission during pre-symptomatic incubation period use time-varying effective reproduction number (
Optical bistability (OB) of Rydberg atoms provides a new, to the best our knowledge, platform for studying nonequilibrium physics and potential resource precision metrology. To date, observation OB has been limited in free space. Here, we explore cavity-enhanced with thermal cesium vapor cell. The signal cavity is enhanced by more than one order magnitude compared that slope phase transition at critical point 10 times without cavity, implying an enhancement two orders sensitivity...
Abstract In medical image processing, fusion is the process of combining complementary information from different or multimodality images to obtain an informative fused in order improve clinical diagnostic accuracy. this paper, we propose a two‐stage framework for computed tomography (CT) and magnetic resonance (MR) images. First, intensity geometric structure features both CT MR are extracted by saliency detection method tensor, respectively, initial obtained. Then, optimized variational...
Abstract Modern neuroimaging technologies have substantially advanced the measurement of brain activity. Electroencephalogram (EEG) as a noninvasive technique measures changes in electrical voltage on scalp induced by cortical With its high temporal resolution, EEG has emerged an increasingly useful tool to study connectivity. Challenges with modeling signals complex activity include interactions among unknown sources, low signal-to-noise ratio, and substantial between-subject heterogeneity....
In this study, the authors propose a variational approach based on total generalised variation (TGV) and local gradient information to fuse multi‐focus images as well medical of computed tomography magnetic resonance. They use second‐order TGV regularisation term fusion weight extract image features. To compute new model effectively, primal‐dual algorithm is carried out. Various experiments are made verify effectiveness proposed methods.
