A Delay-Locked Loop (DLL) with a modified charge pump circuit is proposed for generating high-resolution linear delay steps with sub-picosecond jitter performance and adjustable delay range. The small-signal model of the modified charge pump circuit is analyzed to bring forth the relationship between the DLL's internal control voltage and output time delay. Circuit post-layout simulation shows that a 0.97 ps delay step within a 69 ps delay range with 0.26 ps Root-Mean Square (RMS) jitter performance is achievable using a standard 0.13 µm Complementary Metal-Oxide Semiconductor (CMOS) process. The post-layout simulation results show that the power consumption of the proposed DLL architecture's circuit is 0.1 mW when the DLL is operated at 2 GHz.

Relaxation training can be an important adjunct in reducing symptoms associated with Parkinson's disease (PD). Autogenic Training (AT) is a simple, easily administered and inexpensive technique for retraining the mind and the body to be able to relax. AT uses visual imagery and body awareness to promote a state of deep relaxation.

INTRODUCTION: The occurrence of post-stroke emotional problems is significant during the early post-stroke stage and affects the recovery of functionality among the survivors. Because stroke survivors require active engagement in rehabilitation to optimize the process of neuroplasticity in the initial stage of stroke, there is a need to integrate an intervention, preferably therapists-mediated during rehabilitation, which reduce emotional problems thus improve motivation level among the survivors. One such technique is autogenic relaxation training (ART). ART has been found to reduce anxiety and depression among patients with several medical conditions. However, its usage in stroke survivors during rehabilitation has been limited to date. Therefore, this study is intended to evaluate the effectiveness of ART in addition to usual physiotherapy in improving emotional state and functional level of stroke survivors during rehabilitation.
METHODS: This is an assessor blinded randomized controlled trial comparing 2 intervention approaches namely ART-added physiotherapy (experimental group) and usual physiotherapy (control group). A total of 70 post-stroke patients will be recruited and allocated into either the ART-added physiotherapy or the usual physiotherapy group. The ART-added physiotherapy group will undergo a 20-minute ART session followed by 40 minutes of usual physiotherapy. While the usual physiotherapy group will receive usual physiotherapy alone for 60 minutes. All participants will be treated once a week and are required to carry out a set of home exercises for 2 times per week during the 12-week intervention. Assessment of emotional status and functional independence will be carried out at pre-intervention and week 13 of the intervention with the use of Hospital anxiety and depression scale, Barthel index, and EuroQol-5 dimensions-5 levels. All data will be analyzed using descriptive and inferential statistics.
DISCUSSION: The expected main study outcome is an enhanced evidence-based physiotherapy program that may be used by physiotherapists in the rehabilitation of stroke patients with emotional disturbances.

Successful Treatment of Ptyalism Gravidarum With Concomitant Hyperemesis Using Hypnosis

Ptyalism gravidarum, or sialorrhea, is the excessive secretion of saliva during pregnancy. Treatment of ptyalism gravidarum is often challenging due to its unknown etiologies. This article discusses a case of ptyalism gravidarum with concomitant hyperemesis in which the condition was successfully treated with hypnosis. A 28-year-old woman presented with ptyalism 2 months into her pregnancy and hyperemesis 3 months into pregnancy with associated vomiting that occurred following every meal. Hypnosis was administered at week 16 of pregnancy to eliminate ptyalism and hyperemesis, to prepare for childbirth, and to increase overall psychological well-being. Ptyalism resolved by week 36, concurrent with the final hypnosis session.
