Clinicopathological features associated with lymph node metastasis in early gastric cancer: Analysis of a single-institution experience in China
BACKGROUND: An accurate assessment of potential lymph node metastasis is an important issue for the appropriate treatment of early gastric cancer. Minimizing the number of invasive procedures used in cancer therapy is critical for improving the patientâs quality of life
Exceptional Magnetocaloric Responses in a Gadolinium Silicate with Strongly Correlated Spin Disorder for SubâKelvin Magnetic Cooling
Abstract The development of magnetocaloric materials with a significantly enhanced volumetric cooling capability is highly desirable for the application of adiabatic demagnetization refrigerators in confined spatial environments. Here, the thermodynamic characteristics of a magnetically frustrated spinâ7/2 Gd9.33[SiO4]6O2 is presented, which exhibits strongly correlated spin disorder below â1.5 K. A quantitative model is proposed to describe the magnetization results by incorporating nearestâneighbor Heisenberg antiferromagnetic and dipolar interactions. Remarkably, the recorded magnetocaloric responses are unprecedentedly large and applicable below 1.0 K. It is proposed that the S = 7/2 spin liquids serve as versatile platforms for investigating highâperformance magnetocaloric materials in the subâkelvin regime, particularly those exhibiting a superior cooling power per unit volume
