Objective. To compare ultrasound-guided miniscalpel-needle (UG-MSN) release versus ultrasound-guided dry needling (UG-DN) for chronic neck pain. Methods. A total of 169 patients with chronic neck pain were randomized to receive either UG-MSN release or UG-DN. Before treatment and at 3 and 6 months posttreatment, pain was measured using a 10-point visual(More)
UHF RFID reader transceiver for Chinese local standard (840–845 MHz and 920–925 MHz), in concord with the protocols of EPC Class-1 Gen-2 and ISO/IEC 18000–6C, is presented. A highly linear RF front-end with low flicker noise, an on-chip self-jammer cancellation (SC) circuit with fast time-varying cut-off frequency and a DC-offset cancellation (DCOC) circuit(More)
We present the complete mitochondrial genome of the three-spot grouper Epinephelus trimaculatus (16,761 bp) in this study. The gene order and orientation in E. trimaculatus were the same as the typical vertebrates. The COI and ND4 genes started with the GTG codon and the ATP6 gene started with the CTG codon, the remaining protein-coding genes started with(More)
A 1.8V-to-10V high-voltage tolerant level shifter (HVT level shifter) is presented in this paper. This new topology of HVT level shifter makes all the transistors working in safe operating region, and consequently greatly enhances the circuit's reliability. It has been fabricated in 0.18 µm CMOS process, and successfully integrated in an embedded(More)
A highly linear operational trans-conductance amplifier (OTA) with 3<sup>rd</sup>-order nonlinearity superposition technique is proposed. For achieving high linearity, a native threshold voltage NMOS working in linear region is utilized to obtain the positive 3<sup>rd</sup>-order nonlinear form to compensate the negative 3<sup>rd</sup>-order nonlinear form(More)
