Abstract Background Screening of malignant hematological diseases is great importance for their diagnosis and subsequent treatment. This study constructed an optimal screening model based on routine blood cell parameters. Methods The venous samples 1751 patients collected from 10 tertiary hospitals in China were divided into a training set (1223 cases) validation (528 cases). In addition to the clinical diagnostic information set, 26 parameters including morphological selected using manual...

Reducing the vibration of marine power machinery can improve warships' capabilities concealment and reconnaissance. Being one most effective means to reduce mechanical vibrations, active control technology overcome poor effect in low frequency traditional passive isolation. As vibrations arising from operation are actually frequency-varying disturbances, H ∞ method is adopted suppress disturbances. The solve stability problems caused by uncertainty model reshape response function closed loop...

For a conventional narrowband radar system, its insufficient bandwidth usually leads to the lack of detectable information target, and it is difficult for classify target types, such as rotor helicopter, propeller aircraft, jet aircraft. To address classification problem three different types aircraft joint multifeature method based on micro-Doppler effect in echo caused by micromotion proposed this paper. Through characteristics analysis simulation echoes obtained from scattering point...

Automatic differentiation (AD) is a practical field of computational mathematics that growing interest across many industries, including finance. The use reverse mode AD particularly interesting, since it allows for the computation gradients in same time required to evaluate objective function itself. However, requires excessive memory. This memory requirement can make reverse-mode infeasible some cases (depending on complexity and available RAM) slower than expected others, due secondary...

Entropy engineering is commonly identified as an effective approach for phase stabilization of high-entropy alloys (HEAs). However, this high entropy philosophy in γ/γ′ HEAs seems incompatible with their intermetallic nature. Taking (FeCoNi)86Ti7Al7 object, we theoretically viewed the individual/synergetic contributions and enthalpy to stability HEAs. Our results show that accelerates γ but it shows limited positive effects even negative on γ’ intermetallics, especially vibrational entropy....

Abstract The emerging of molecular spintronics offers a unique chance for the design devices with different spin-state, and control spin-state becomes essential spin switches. However, intrinsic switching from low-spin to high-spin state is temperature-dependent process small energy barrier that low temperature required maintain state, thus room-temperature operation single-molecule have not yet been achieved. Here, we investigated charge transport through diamagnetic square planar...
