The reefs in the Xiannüdong Formation (Cambrian Series 2) are the oldest archaeocyathan–microbial bioconstructions in China, but the details of their microbial structures have not been previously described. However, a new section at Tangjiahe site, northern Sichuan Province, contains very well-preserved microbial fabrics that provide these details, and is described in this study. The Tangjiahe section contains three levels of reefal buildups that were constructed by a consortium of archaeocyaths and calcimicrobes in varying proportions. The lowest (oldest) reefal buildup is a calcimicrobial biostrome, possibly in the form of a wide mound with a low relief (unconfirmed due to outcrop limitation), which was formed by Epiphyton with rare small archaeocyaths, and is sandwiched by flat-pebble conglomerates. The middle reefal buildup is a high-relief calcimicrobial mound, enclosed by oolites, that was built by intergrown Renalcis and Tarthinia. Archaeocyath fossils are uncommon, and were bound into the framework by microbial carbonates. The uppermost (youngest) reefal buildup is a low-relief archaeocyathan mound lacking calcimicrobes but partly having microbially-clotted textures attached on archaeocyaths. Calcimicrobes built or aided archaeocyaths to form the framework of Tangjiahe reefs. The three buildups formed in low-energy lagoons behind ooid shoals, and the environment was nutrient-rich due to terrigenous influx from adjacent lands. Tangjiahe reefs thus resemble most Early Cambrian reefs, in settings consistent with eutrophic, calm environments, and are characterized by the domination or aid of calcimicrobial components in framework construction. 展开更多

The rapid development of information and communication technologies(ICTs)and cyber-physical systems(CPSs)has paved the way for the increasing popularity of smart products.Context-awareness is an important facet of product smartness.Unlike artifacts,various bio-systems are naturally characterized by their extraordinary context-awareness.Biologically inspired design(BID)is one of the most commonly employed design strategies.However,few studies have examined the BID of context-aware smart products to date.This paper presents a structured design framework to support the BID of context-aware smart products.The meaning of context-awareness is defined from the perspective of product design.The framework is developed based on the theoretical foundations of the situated function-behavior-structure ontology.A structured design process is prescribed to leverage various biological inspirations in order to support different conceptual design activities,such as problem formulation,structure reformulation,behavior reformulation,and function reformulation.Some existing design methods and emerging design tools are incorporated into the framework.A case study is presented to showcase how this framework can be followed to redesign a robot vacuum cleaner and make it more context-aware. 展开更多

In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related toObservatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-raybinaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellentlysuited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium ledby the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in themid 2020s. 展开更多

It is a new way for oceanographic remote sensing using the GNSS-Reflection technique. Sea waves, tides and sea surface wind can be obtained by analyzing the direct and reflected GPS signals from sea surface. It has become an advanced field concerned by many researchers. In this paper the first China Ocean Reflection Experiment (CORE) with the coastal GNSS-R in the southeast is reported and the method to retrieve oceanographic parameters with the direct and reflected GPS signals is studied. The primary retrievals of Significant Wave Height (SWH) are presented and also compared with the meas-urements from Ultrasonic Wave Gauge (UWG) in situ. 展开更多

Historically,patients undergoing liver transplantation were left intubated and extubated in the intensive care unit(ICU)after a period of recovery.Proponents of this practice argued that these patients were critically ill andneed time to be properly optimized from a physiological and pain standpoint prior to extubation.Recently,there has been a growing movement toward early extubation in transplant centers worldwide.Initially fueled by research into early extubation following cardiac surgery,extubation in the operating room or soon after arrival to the ICU,has been shown to be safe with proper patient selection.Additionally,as experience at determining appropriate candidates has improved,some institutions have developed systems to allow select patients to bypass the ICU entirely and be admitted to the surgical ward after transplant.We discuss the history of early extubation and the arguments in favor and against fast track anesthesia.We also described our practice of fast track anesthesia at Mayo Clinic Florida,in which,we extubate approximately 60%of our patients in the operating room and send them to the surgical ward after a period of time in the post anesthesia recovery unit. 展开更多

Ischemia occurs in diabetic retinopathy with neuronal loss, edema, glial cell reactivity and oxidative stress. Epacs, consisting of Epac1 and Epac2, are c AMP mediators playing important roles in maintenance of endothelial barrier and neuronal functions. To investigate the roles of Epacs in the pathogenesis of ischemic retinopathy, transient middle cerebral artery occlusion(t MCAO) was performed on Epac1-deficient(Epac1-/-) mice, Epac2-deficient(Epac2-/-) mice, and their wild type counterparts(Epac1+/+ and Epac2+/+). Two-hour occlusion and 22-hour reperfusion were conducted to induce ischemia/reperfusion injury to the retina. After t MCAO, the contralateral retinae displayed similar morphology between different genotypes. Neuronal loss, retinal edema and increase in immunoreactivity for aquaporin 4(AQP4), glial fibrillary acidic protein(GFAP), peroxiredoxin 6(Prx6) were observed in ipsilateral retinae. Epac2-/- ipsilateral retinae showed more neuronal loss in retinal ganglion cell layer, increased retinal thickness and stronger immunostaining of AQP4, GFAP, and Prx6 than those of Epac2+/+. However, Epac1-/- ipsilateral retinae displayed similar pathology as those in Epac1+/+ mice. Our observations suggest that Epac2-deficiency led to more severe ischemic retinopathy after retinal ischemia/reperfusion injury. 展开更多

OBJECTIVE:To examine the effects of a greens alkalizing dietary supplement on urinary pH levels in individuals with lower-than-average pH levels.METHODS:The present study investigated the effects of an alkalizing formula(Reserveage Wholeganic GreensTM)on four individuals who had average urinary pH levels below 6.0 for three consecutive days.Following the three-day,baseline period,participants received Reserveage Wholeganic GreensTMfor four consecutive days and were instructed to continue to measure their urine pH levels.Paired samples t-tests were used to examine pH levels before and after a four-day treatment period with Reserveage Wholeganic GreensTM.RESULTS:Compared to baseline,mean urine pH levels in all volunteers were significantly higher following the supplementation with Reserveage Wholeganic GreensTM(5.89±0.20 vs 5.56±0.23;P<0.01).Participants’pH levels were also significantly higher than baseline on days 5,6,and 7 of the treatment period(P<0.05).Noteworthy,on day 7,participants’mean pH levels were significantly higher than at the beginning of the treatment period(6.03±0.15 at day 7 vs5.65±0.24 at day 4;P<0.01).CONCLUSION:The findings of this study suggest that supplementation with Reserveage Wholeganic GreensTMhas an alkalizing effect on the body and can increase the urine pH levels in individuals with lower-than-average pH levels. 展开更多
