A Variable-Sampling Time Model Predictive Control Algorithm for Improving Path-Tracking Performance of a Vehicle.

This paper proposes a novel model predictive control (MPC) algorithm that increases the path tracking performance according to the control input. The proposed algorithm reduces the path tracking errors of MPC by updating the sampling time of the next step according to the control inputs (i.e.

Effect of Internal Pores Formed by a Superabsorbent Polymer on Durability and Drying Shrinkage of Concrete Specimens.

In this study, the effect of internal pores formed by a superabsorbent polymer (SAP) was analyzed by evaluating the compressive strength, chloride penetration depth, drying shrinkage, and pore size distribution of SAP-containing concrete, while securing workability using a water-reducing agent (WRA). The experimental results showed that the amount of WRA necessary increased as the amount of SAP added increased, and that the compressive strength was the highest when the SAP content was 1.5% of the concrete mix.

Therapeutic decision-making in elderly patients with acute myeloid leukemia: conventional intensive chemotherapy versus hypomethylating agent therapy.

Standards of care for elderly acute myeloid leukemia (AML) patients unfit for intensive chemotherapy remain undefined. We aimed to compare outcomes of hypomethylating agent (HMA) therapy and intensive chemotherapy (IC) in elderly AML patients and identify the subgroup of patients who are eligible for HMA therapy. We reviewed data on the outcomes of 86 AML patients aged ≥ 65 years, who had undergone treatment between 2010 and 2015.

Transaxillary subpectoral implantation of implantable pulse generator for deep brain stimulation.

Objectives: Deep brain stimulation (DBS) is an effective modality of treating cardinal motor symptoms of several movement disorders such as Parkinson's disease, essential tremor, and dystonia. Although hardware-related complications of DBS have been reported, the cosmetic satisfaction and discomfort associated with infraclavicular subcutaneous implantation of the pulse generator has not been described. The authors adopted a technique of transaxillary subpectoral implantable pulse generator (IPG) placement and investigated the difference in the discomfort, cosmetic satisfaction, mean operation time for IPG implantation, and severity of postoperative pain between infraclavicular subcutaneous placement and transaxillary subpectoral implantation of IPG.

A warm footbath improves coronary flow reserve in patients with mild-to-moderate coronary artery disease.

Backgrounds: Recent studies have shown that thermal therapy by means of warm waterbaths and sauna has beneficial effects in chronic heart failure. However, a comprehensive investigation of the hemodynamic effects of thermal vasodilation on coronary arteries has not been previously undertaken. In this study, we studied the effect of a warm footbath (WFB) on coronary arteries in patients with coronary artery disease (CAD), as well as any adverse effect.

Ultrasonic measurement of fetal parameters for estimation of gestational age in Korean black goats.

The objective of this study was to determine relationship of gestational age with measurement of diameter of head, orbit, trunk, long and short axis of heart, aorta, placentome, umbilical cord and umbilical vein in Korean black goats. In this study, ten pregnant Korean black goats (Capra hircus aegagrus) were used. Pregnancy diagnosis was performed with a 5 MHz linear transducer and ultrasonographic scan were performed at 60, 75, 90, 105, 120 and 135 days after mating with a 4-9 MHz convex transducer.
