This paper describes an approximated-scalar-sign-function-based anti-windup digital control design for analog nonlinear systems subject to input constraints. As input saturation occurs, the non-smooth saturation constraint is modeled with the approximated scalar sign function which is a smooth nonlinear function. The resulting nonlinear model is further linearized at any operating point with the optimal linearization technique, and Linear Quadratic Regulator (LQR) is then applied for a state-feedback controller optimal for each operating point. As input saturation is encountered, an iterative procedure is developed to adjust control gains by systematically updating LQR weighting matrices until the inputs lie within the saturation limits. Through global digital redesign, the analog LQR controller is converted to an equivalent digital one for keeping the essential control performance, and moreover, delay compensation is taken into account during digital redesign for compensating the potential time delays in a control loop. The swing-up and stabilization control of single rotary inverted pendulum system is used to illustrate and verify the proposed method.

Background Gastroesophageal reflux disease （GERD） is a common disorder. Dilation of intercellular spaces of esophageal epithelium has been revealed at transmission electron microscopy both in the rabbit acid-perfused esophagus and in esophageal biopsies from GERD patients. This study aimed to observe the changes of the intercellular spaces of squamous epithelium of lower esophagus in patients with GERD and the changes of intercellular spaces of patients with erosive esophagitis （EE） before and after omeprazole treatment. Methods Outpatients having GERD symptoms for more than 3 months and volunteers were collected. All of them underwent gastroendoscopy and 24-hour ambulatory pH monitoring. Biopsies were taken from the lower esophagus （2 cm above Z-line） for electron microscope examination. Five healthy volunteers, six non-erosive reflux disease （NERD） patients, and five EE patients were enrolled. Intercellular spaces of GERD patients and controls were calculated. Then we selected 20 patients with EE diagnosed by gastroendoscopy. All of them were treated with omeprazole （Losec, 20 mg bid） for 4 weeks then underwent gastroendoscopy again. Biopsies were taken from 2 cm above Z-line for electron microscope examination. All the patients completed the questionnaire about reflux symptoms before and after treatment. Results Intercellular spaces of esophageal epithelial cell in volunteers, NERD patients and EE patients were （0.37±0.07）μm, （1.31±0.08）μm, and （1.33±0.14）μm, respectively, with significant differences between the control group and the NERD group （P=0.000）. In the 20 EE patients, the mean intercellular space before treatment was （1.14±0.15） μm After treatment the intercellular space was （0.51±0.18）μm, a significant difference compared with pre-treatment measurements （P=0.000）. Conclusions Dilated intercellular spaces （DIS） were seen in both NERD and EE cases. The dilated intercellular spaces of esophaaeal epithelium in EE patients could be recovered after a sh

Objective: To observe the clinical efficacy of acupuncture on back-shu points of five zang in treating chronic fatigue syndrome(CFS).Methods: Sixty patients were randomized into treatment group and control group. In treatment group,the back-shu points of five zang organs were adopted for acupuncture. shènshū(肾俞 BL23) was perpendicularly needled 15-30 mm in depth. The rest of the selected points were inserted obliquely 15-30 mm in the direction of the spine with even method of lifting-thrusting and twisting-twirling, 10 s for each acupoint. In control group, the acupoints were approximately 1.5-2 cm away outward from the back-shu points of five zang organs(about on the middle of the two sidelines of the bladder meridian of foottaiyang) and the points from the bladder meridian of foot-taiyang were excluded. Acupoints were needled6-9 mm in depth, and deqi was not required, without any manipulation. The treatments were carried out twice a week for twenty minutes each time, a total of eight treatments were given. The clinical efficacy of acupuncture treatment for CFS was evaluated through the Fatigue Scale-14(FS-14) and the Symptom Check-List 90(SCL-90) after ***: The total effective rate was 86.67% in the treatment group and 53.33% in the control group(P<0.01). In treatment group, FS-14 total scores, somatic fatigue scores, and mental fatigue scores were significantly reduced than before treatment(all P<0.01). In control group, FS-14 total scores and somatic fatigue scores were significantly reduced(both P<0.01). The improvement of FS-14 total scores, somatic fatigue scores, and mental fatigue scores in the treatment group were better than those in the control group(P<0.01, P<0.05). After treatment, SCL-90 total scores and somatization, compulsion, interpersonal sensitivity, depression, anxiety, hostility, psychoticism, and other factors scores were significantly reduced in the treatment group compared with before treatment(P<0.01).

《论语先进》“先进于礼乐,野人也。后进于礼乐,君子也。如用之,则吾从先进”一章,历来众说纷纭,难得确解。旧解多谓“先进”、“后进”或“先进于礼乐”、“后进于礼乐”各自成词,联系上古时期的语言特点,“先进”“后进”以及“先进于礼乐”“后进于礼乐”皆不成词。此处“进”当为“进献”义,同“荐”,“于”义同“以”,“野人”为孔子时代居于城外的殷代遗民,那么“先进于礼乐,野人也;后进于礼乐,君子也。”,即“(祭祀时)先施礼奏乐的是城外的殷人,后施礼奏乐的是国都里的贵族”,如此理解,正好可以和《礼记郊特牲》“殷人尚声,臭味未成,涤荡其声,乐三阕,然后出迎牲”相互印证。孔子对殷周礼俗的态度是择善而从的。

通过对北海咸水歌的传承状况调查研究,分析其濒危原因,认为北海咸水歌传统的传承和传播运行机制以人际传播为主,与民间礼俗息息相关。而大众传媒的介入,使得北海咸水歌传承传播在变迁中呈现双重特质——官方政策、法律和法规的宣传作用、与民间礼俗息息相关的人际传播载体的咸水歌活动。探索出以传承人为核心支点的咸水歌活态传承机制及传播发展机制,认为只有通过"活"的传播,咸水歌才有更广泛的受众对象,以及更广阔的土壤空间,才会爆发出蓬勃的生命力。
