Sight obstructions along road curves can lead to a crash if the driver is not able to stop the vehicle in *** is a particular issue along curves with limited available sight,where speed management is necessary to avoid unsafe situations(e.g.,driving off the road or invading the other traffic lane).To solve this issue,we proposed a novel intelligent speed adaptation(ISA)system for visibility,called V-ISA(intelligent speed adaptation for visibility).It estimates the real-time safe speed limits based on the prevailing sight conditions.V-ISA comes with three variants with specific feedback modalities(1)visual and(2)auditory information,and(3)direct intervention to assume control over the vehicle ***,we investigated the efficiency of each of the three V-ISA variants on driving speed choice and lateral behavioural response along road curves with limited and unsafe available sight distances,using a driving *** also considered curve road geometry(curve direction:rightward ***).Sixty active drivers were recruited for the *** half of them(experimental group)tested the three V-ISA variants(and a V-ISA off condition),the other half always drove with the V-ISA off(validation group).We used a linear mixed-effect model to evaluate the influence of V-ISA on driver *** V-ISA variants were efficient at reducing speeds at entrance points,with no discernible negative impact on driver lateral *** rightward curves,the V-ISA intervening variant appeared to be the most effective at adapting to sight *** of the current study implies that V-ISA might assist drivers to adjust their operating speed as per prevailing sight conditions and,consequently,establishes safer driving conditions.

We hypothesized that slowed oxygen uptake(Vo_(2))kinetics for exercise transitions to higher power outputs(Po)within the steady state(SS)domain would increase the mean response time(MRT)with increasing exercise intensity during incremental *** highly trained cyclists(mean±standard deviation[SD]);age(39±6)years[yr];and Vo_(2) peak=(61±9)ml/kg/min performed a maximal,ramp incremental cycling test and on separate days,four 6-min bouts of cycling at 30%,45%,65%&75% of their incremental peak Po(Wpeak).SS trial data were used to calculate the MRT and verified by mono-exponential and linear curve *** the ramp protocol attained the value from SS,the Po,in Watts(W),was converted to time(min)based on the ramp function W to quantify the incremental MRT(iMRT).Slope analyses for the Vo_(2) responses of the SS versus incremental exercise data below the gas exchange threshold(GET)revealed a significant difference(p=0.003;[0.437±0.08]vs.[0.382±0.05]l·min^(-1)).There was a significant difference between the 45%Wpeak steady state Vo_(2)(ss Vo_(2))([3.08±0.30]l·min^(-1),respectively),and 30% Wpeak ss Vo_(2)(2.26±0.24)(pl·min^(-1))and between the iMRT for 45% and 30% Wpeak ss Vo_(2) values([50.58±36.85]s vs.[32.20±43.28]s).These data indicate there is no single iMRT,which is consistent with slowed Vo_(2) kinetics and an increasing Vo_(2) deficit for higher exercise intensities within the SS domain.

Traumatic brain injury(TBI)is a public health problem with an undue economic burden that impacts nearly every age,ethnic,and gender group across the globe(Capizzi et al.,2020).TBIs are often sustained during a dynamic range of exposures to energetic environmental forces and as such outcomes are typically heterogeneous regarding severity and pathology(Capizzi et al.,2020).

Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related death in Asian and African countries due to a high prevalence of chronic hepatitis B infections(1,2).The vast majority of current studies focus on the treatment of HCC itself rather than complications from HCC.A potentially life-threatening complication of HCC is spontaneous rupture,and its prevalence has been reportedly to be 5-15%of all HCC cases(1).This is the third leading cause of HCC-related death after tumor progression and liver failure,and there is a high mortality associated with rupture(3,4).

Adaptive neural network control of a 2-DoF helicopter system considering input constraints and global prescribed performance

In this study, an adaptive neural network(NN) control is proposed for nonlinear two-degree-offreedom(2-DoF) helicopter systems considering the input constraints and global prescribed ***, radial basis function NN(RBFNN) is employed to estimate the unknown dynamics of the helicopter system. Second, a smooth nonaffine function is exploited to approximate and address nonlinear constraint functions. Subsequently, a new prescribed function is proposed, and an original constrained error is transformed into an equivalent unconstrained error using the error transformation and barrier function transformation methods. The analysis of the established lyapunov function proves that the controlled system is globally uniformly bounded. Finally, the simulation and experimental results on a constructed Quanser's test platform verify the rationality and feasibility of the proposed control.

The Making of a Health Profession:How Chinese Medicine Became a Nationally Registered Allied Health Profession in Australia

引用

Chinese Medicine and Culture 2024年第1期7卷 51-62页

作者： John l McDonald Judy B James School of Chinese Medicine Endeavour College of Natural HealthSouthport 4215Australia Acupuncture Now Australia Brisbane 4120Australia

In 2012, traditional Chinese medicine(TCM) practitioners in Australia became nationally-registered allied health professionals in three categories: acupuncturist, Chinese herbal medicine practitioner, and Chinese herbal medicine dispenser. Australia was the first Western country to introduce national registration for Chinese medicine, followed by Portugal and, recently, New Zealand. The practice of TCM in Australia can be traced back to the beginning of Chinese immigration to Australia during the Victorian Gold Rush which began in the 1850s. The process which led to national registration commenced in the early 1970s with the establishment of the first acupuncture courses. Decades of gradual development of courses from unaccredited part-time diplomas to accredited bachelor degrees, and the development, by the profession, of national consensus on educational standards were essential elements in the process which led to registration. Professional associations, such as the Australian Acupuncture and Chinese Medicine Association ltd.(AACMA), also developed a framework of professional selfregulation, including codes of Ethics, codes of conduct, ongoing professional development requirements and Infection control Guidelines, and provided leadership in the development of the profession. After decades of tribalism and division within the TCM profession, the National Academic Standards committee brought almost all stakeholders together to reach a consensus on the Australian Guidelines for Traditional Chinese Medicine Education which were published by AACMA in 2001. Professional associations also collaborated on joint submissions to the government in support of registration, which was introduced first in the state of Victoria in 2000, and subsequently became national in 2012. Despite national registration, some barriers still remain, and professional associations continue to lobby the federal government for inclusion in Medicare, chronic disease management scheme, and Veterans
