PURPOSE Impacts on hemolysis and backflow using a non-occlusive setting with the Better-Header (BH) roller pump were investigated. METHODS AND RESULTS Pump flow of a non-occlusion setting was measured with a pump speed of 3 L/min and 5 L/min against various after-loads. With the non-occlusive setting (BH-NO350), backflow was less than 10% if the pump pressure head was <300 mmHg. When the outl...

In this paper, a low-voltage, high performance charge pump circuit, suitable for implementation in standard CMOS technologies is proposed. Its pumping operation is based on cascading several crossconnected NMOS voltage doubler stages. For very low-voltage applications (1.2 V, 0.9 V), where the performance of the NMOS transistors is limited due to body effect, two improved versions of the charge...

AIMS To compare insulin pump therapy and multiple daily injections (MDI) in patients with type 2 diabetes receiving basal and prandial insulin analogues. METHODS After a 2-month dose-optimization period, 331 patients with glycated haemoglobin (HbA1c) levels ≥8.0% and ≤12% were randomized to pump therapy or continued MDI for 6 months [randomization phase (RP)]. The MDI group was subsequently s...

A charge pump (CP) that has low current mismatch to reduce the locking time of Phase-Locked Loop (PLL) is proposed. The design promising in 5G applications with capabilities fast settling and power consumption. In this design, a architecture consists an operational amplifier (OPA), switches, three D flip-flops (DFFs) passive devices. phase error compensation technique introduced time. mismatch,...

A heat pump system requires proper refrigerant charge amount. Once refrigerant is charged into a heat pump system, its charge amount is fixed. For this reason, prediction of optimal refrigerant charge amount is very important in order to yield best performance. Too low charge amount degrades capacity of heat pump. On the other hand, excessive charge amount decreases coefficient of performance (...

The correlation functions of an ionic fluid with charge and size asymmetry are studied within the framework of the random phase approximation. The results obtained for the charge-charge correlation function demonstrate that the second-moment Stillinger-Lovett (SL) rule is satisfied away from the gas-liquid critical point (CP) but not, in general, at the CP. However, in the special case of a mod...

In this brief note, we suggest that the accumulating neutrino data [1–3], including the recent results from KamLAND [4] and K2K [5], point to a relatively simple neutrino mass matrix. The data can be explained by oscillations between three active neutrinos with the atmospheric neutrino and K2K data explained by oscillation between the muon and the tauon neutrinos, and the solar neutrino and Kam...

In this article, theoretical studies on the selective complexation of the halide ions (F¯, Cl¯ and Br¯) and ion pairs (Na+F¯, Na+Cl¯ and Na+Br¯) with the cyclic nano-hexapeptide (CP) composed of L-proline have been performed in the gas phase. In order to calculate the dispersion interaction energies of the CP and ions, DFT-D3 calculations at the M05-2X-D3/6-31G(d) level was employed. Based on t...
