Existing studies do not effectively solve the problem, and there still exist various sensor data pre-processing optimisation problems at the acquisition end in crowd-sensing process. This study presents an improved sliding average method to achieve data compression and reduce the time complexity by using a dynamic window with improved processing time. Through adopting locally sorting and gradient change of the filter window, an improved extremum median filtering method is proposed to relieve the time- consuming problem when denoising high pixel images. A transmission strategy for optimisation is also proposed, in which only the demarcation points of each group of data and the data points with large differences when comparing with the demarcation points are recorded. This strategy reduces the storage pressure and the amount of data transmission of mobile terminal and improves the efficiency of data transmission. The experimental results show that their methods have higher speed and lower cost, and thus they can run better in crowd-sensing environment.展开更多

The insular cortex is a cortical representation of obstructive sleep apnea syndrome. The habenular nucleus is a station for descending insular cortex activity. OBJECTIVE： Through actively stimulating the rat insular cortex, to observe rat respiratory movement, myoelectric activities of genioglossus, arterial partial pressure of oxygen, partial pressure of carbon dioxide and acidity-alkalinity, and to verify a hypothesis that the insular cortex is a superior-position regulation center, and the habenular nucleus is an inferior-position nervous nuclei of the insular cortex in patients with obstructive sleep apnea syndrome. DESIGN, TIME AND SETTING： The randomized, controlled animal study was performed at the Laboratory of Electrophysiology, Department of Physiology, Norman Bathune College of Medicine, Jilin University, China from September 2004 to June 2008. MATERIALS： We used L-glutamic acid （Dingguo Biological Product Research Center, Beijing, China）, lidocaine hydrochloride （Seventh Pharmacy Co., Ltd., Wuxi, China）, electric stimulator （Nihon Kohden, Japan）, and an AVL-OPTI blood gas analyzer （AVL Scientific Co., Roswell, GA, USA）. METHODS： The insular cortex of healthy adult Wistar rats underwent electrostimulation and L-glutamic acid stimulation to record changes in the myoelectric activity of genioglossus and respiratory movement. Some rats were injected with lidocaine to block the habenular nucleus before electrostimulation or L-glutamic acid stimulation. L-glutamic acid and lidocaine were injected by microelectrodes embedded in nuclear groups. MAIN OUTCOME MEASURES： Myoelectric activities of genioglossus, arterial partial pressure of oxygen, partial pressure of carbon dioxide and acidity-alkalinity were measured following apnea in rats undergoing electrostimulation in the insular cortex and following blockade of the habenular nucleus. RESULTS： Following electrostimulation and L-glutamic acid stimulation, rats developed apnea or respiratory rhythm disorders. Simultaneously, the amplitude of myoelectric activity of the genioglossus was reduced （P 〈 0.01 ）, and the electromyogram integral was decreased （P 〈 0.01）. Arterial blood gas analysis showed arterial blood acidosis, a decrease in pH （P 〈 0.05）, and an increase in the negative value of alkaline reserve （P 〈 0.01）. Lidocaine in the habenular nuclear blocked respiratory and other index changes after insular cortex stimulation. CONCLUSION： Dyspnea induced by stimulating the insular cortex may require the habenular nucleus. Paralysis of the habenular nucleus can completely eliminate insular cortex stimulation-induced dyspnea.展开更多

In addition, arterial blood gas analysis showed arterial blood acidosis, reduced pH values, increased alkali reserve negative values, decreased peripheral blood 5-hydroxytryptamine content, and increased 5-hydroxytryptamine expression in cerebellar Purkinje cells. Following lidocaine injection to block the habenular nucleus, abnormalities in breath, genioglossal electromyogram, and blood gas values disappeared, and peripheral blood 5-hydroxytryptamine content returned to levels prior to electric stimulation. However, 5-hydroxytryptamine expression in cerebellar Purkinje cells remained high. The results suggested that 5-hydroxytryptamine expression in Purkinje cells did not correlate with ventilation function involving insular cortex and habenular nucleus.展开更多

In the present study, respiratory motion curve of the genJoglossus muscle and peripheral 5-hydroxytryptamine changes were observed following L-glutamate stimulation of the habenular nucleus of adult Wistar rats. Results showed that the rats had apnea and decreased plasma 5-hydroxytryptamine content after the neurons in habenular nucleus were excited. Genioglossus muscle electromyogram amplitude and integral were significantly reduced. The genioglossus myoelectric activity and respiratory motion curve were similar to obstructive sleep apnea syndrome, thus confirming that the habenular nucleus is the key nucleus involved in the pathogenesis of obstructive sleep apnea syndrome, and is the primary regulated center in the raphe nuclei. Stimulation of the habenular nucleus may suppress 5-hydroxytryptamine release and result in apnea, which is similar to obstructive sleep apnea syndrome.展开更多

In addition, arterial blood gas analysis showed arterial blood acidosis, reduced pH values, increased alkali reserve negative values, decreased peripheral blood 5-hydroxytryptamine content, and increased 5-hydroxytryptamine expression in cerebellar Purkinje cells. Following lidocaine injection to block the habenular nucleus, abnormalities in breath, genioglossal electromyogram, and blood gas values disappeared, and peripheral blood 5-hydroxytryptamine content returned to levels prior to electric stimulation. However, 5-hydroxytryptamine expression in cerebellar Purkinje cells remained high. The results suggested that 5-hydroxytryptamine expression in Purkinje cells did not correlate with ventilation function involving insular cortex and habenular nucleus.

文摘5-hydroxytryptamine contributes to the control of activities of the dilator muscle in the upper respiratory tract, and is derived from the raphe nuclei, in which the habenular nucleus exerts a sustaJned inhibitory effect. In the present study, respiratory motion curve of the genJoglossus muscle and peripheral 5-hydroxytryptamine changes were observed following L-glutamate stimulation of the habenular nucleus of adult Wistar rats. Results showed that the rats had apnea and decreased plasma 5-hydroxytryptamine content after the neurons in habenular nucleus were excited. Genioglossus muscle electromyogram amplitude and integral were significantly reduced. The genioglossus myoelectric activity and respiratory motion curve were similar to obstructive sleep apnea syndrome, thus confirming that the habenular nucleus is the key nucleus involved in the pathogenesis of obstructive sleep apnea syndrome, and is the primary regulated center in the raphe nuclei. Stimulation of the habenular nucleus may suppress 5-hydroxytryptamine release and result in apnea, which is similar to obstructive sleep apnea syndrome.

文摘In order to achieve the goal of circular economy and sustainable development of ecological environment,it is important to separate and recover associated elements from rare mineral resources.Compared with traditional physical and che-mical remediation methods of contaminated soil,phytoremediation is regarded as the most promising green in-situ restoration technology.The purpose of this review is to efctive alleviate the environmental problems caused by rare tailings contaminated soil through phytoremediation and realize the recovery of uranium-thorium,rare earth elements(REEs)and tantalum niobium.This review took rare tailings with uranium-thorium,REEs tantalum-niobium in China as the research object,then the background,significance,mechanisms and applcation strategies of phytoremediation were elaborated.In additon,the cases of spedies with tolerance to uranium thorium,tantalum niobium as well as REEs and their remediation mechanisms were summarized,respectively.Particularly,the typical plants represented by Bras-sica juncea,Sunflower,Phytolacca americana,Dicramopteris dichotoma,Salix SPP,etc,were very efctive in the reme-diation of rare tailings.The infuence factors of phytoremediation eficiency of tailings contaminated soil were discused.Two main factors were the mobility of heavy metals in soil(external cause)and the ennichment ability of species(inter-nal cause).Since the traditional phytoremediation also had some limitations in view of this,the work discussed some auxiliary methods(such as chelaing agents or microbial assisted restoration)to improve the effiency of phytoreme-diation.Finally,the future development of phytoremediation and potential applcation directions were explored.

文摘In mass spectrometry(MS)analysis,carryover is a common and unavoidable problem.It causes over-estimation of analyte levels,which significantly influences accuracy and precision.Therefore,there are strict limits on carryover in MS-based assays.The conventional capillary-based electrospray ionization(ESI)restricts the use of MS for real-time monitoring,where a prompt response is crucial.Recently,we have developed a micro probe electrospray ionization(mPESI)coupled with MS(mPESI-MS)technology,enabling MS analysis within 40 s without a chromatographic column[1].However,the challenge of carryover arises when trying to make the micro probe reusable for resource-saving purposes.Considering that dielectric barrier discharge(DBD)plasma is effective in degrading contaminants in water and gas[2],we hypothesized the eventual use of the DBD plasma to“wash”the micro probe.Then,a DBD plasma wash tube(DBD-WT)was introduced for rapid carryover elimination in mPESI-MS analysis.

文摘Mechanical stress modulates bone formation and organization of the extracellular matrix(ECM),the interaction of which affects heterotopic ossification(HO).However,the mechanically sensitive cell populations in HO and the underlying mechanism remain elusive.Here,we show that the mechanical protein Polysyctin-1(PC1,Pkd1)regulates CTSK lineage tendon-derived mesenchymal stem cell(TDMSC)fate and ECM organization,thus affecting HO progression.First,we revealed that CTSK lineage TDMSCs are the major source of osteoblasts and fibroblasts in HO and are responsive to mechanical cues via single-cell RNA sequencing analysis and experiments with a lineage tracing mouse model.Moreover,we showed that PC1 mediates the mechanosignal transduction of CTSK lineage TDMSCs to regulate osteogenic and fibrogenic differentiation and alters the ECM architecture by facilitating TAZ nuclear translocation.Conditional gene depletion of Pkd1 or Taz in CTSK lineage cells and pharmaceutical intervention in the PC1-TAZ axis disrupt osteogenesis,fibrogenesis and ECM organization,and consequently attenuate HO progression.These findings suggest that mechanically sensitive CTSK-lineage TDMSCs contribute to heterotopic ossification through PC1-TAZ signaling axis mediated cell fate determination and ECM organization.

文摘Pathological cardiac hypertrophy contributes to the development of heart failure(HF).NOL1/NOP2/Sun domain family member 2(NSUN2)is implicated in pathophysiological processes of many diseases.However,the function and operation of NSUN2 in cardiac hypertrophy and HF remain unclear.Here,we observed a significant increase in the levels of NSUN2 expression in both human hearts with HF and in mouse hearts with hypertrophy induced by transverse aortic constriction(TAC)and angiotensin II(Ang II)treatment.Cardiomyocyte-specific knockout of NSUN2 attenuated the reduced cardiac ejection fraction(EF)and fractional shortening(FS)and the increased heart weight to tibial length(HW/TL)upon either TAC or Ang II infusion.Conversely,cardiac-specific overexpression of NSUN2 resulted in cardiac remodeling as indicated by a prominent increase in hypertrophic growth and cardiac fibrosis and a robust decline in cardiac EF and FS.Mechanistically,NSUN2 induces 5-methylcytosine(m5C)modification of La-related protein 1(LARP1)to enhance its messenger RNA(mRNA)stability,which is mediated by Y-box binding protein 1(YBX1).Increased LARP1 further interacts with GATA binding protein 4(GATA4)mRNA and prevents its degradation.LARP1 silencing partially attenuates TAC and NSUN2 induced cardiac hypertrophy and HF.Collectively,this study provides a new insight into the central role of NSUN2 in cardiac hypertrophy,indicating that NSUN2 may serve as a novel therapeutic target for HF.

文摘A 50 mm balloon-borne white-light coronagraph(BBWLC)to observe white-light solar corona over the altitude range from 1.08 R_(⊙)to 1.50 R_(⊙)has recently been indigenously developed by Yunnan Observatories in collaboration with Shandong University(in Weihai)and Changchun Institute of Optics,Fine Mechanics and Physics,which will significantly improve the ability of China to detect and measure the inner corona.On 2022 October 4,its first scientific flight took place at the Dachaidan area in Qinghai province of China.We briefly describe the BBWLC mission including its optical design,mechanical structure,pointing system,the first flight and results associated with the data processing approach.Preliminary analysis of the data shows that BBWLC imaged the K-corona with three streamer structures on the west limb of the Sun.To further confirm the coronal signals obtained by BBWLC,comparisons were made with observations of the K-coronagraph of the High Altitude Observatory and the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory.We conclude that BBWLC eventually observed the white-light corona in its first scientific flight.

文摘Grain filling is a critical determinant of yield and quality in rice.This study aims to clarify the association between grain photosynthesis and the filling rate of rice varieties with different grain weights,providing a theoretical foundation for optimizing grain-filling processes.Two rice varieties with similar growth duration but different grain weights were selected:a large-grain variety,Lingliangyou 268(L268),and a small-grain variety,Ruiliangyou 1053(R1053).Differences in grain filling,grain photosynthetic rate,and grain chlorophyll content were systematically examined during the filling stage.Results showed significant differences in grain-filling,grain photosynthetic rate,and grain chlorophyll content between large-grain and small-grain rice varieties.The grain photosynthetic rate of L268 was a significantly higher than R1053.L268 also exhibited significantly higher initial grain filling rate,maximum grainfilling rate,and mean grain filling rate compared to R1053.Throughout the grain filling period,L268 showed higher grain chlorophyll content(including chlorophyll a,chlorophyll b,and total chlorophyll)than R1053.The increase in chlorophyll content,particularly total chlorophyll,enhanced the grain photosynthetic rate during the early and middle stages of grain filling significantly.These findings suggested that rice varieties with higher grain weights exhibited stronger panicle photosynthetic capacity due to their higher chlorophyll content.The enhanced grain photosynthetic rate contributed to improved grain filling and increased grain weight.

文摘With the increasing importance of multimodal data in emotional expression on social media,mainstream methods for sentiment analysis have shifted from unimodal to multimodal approaches.However,the challenges of extracting high-quality emotional features and achieving effective interaction between different modalities remain two major obstacles in multimodal sentiment analysis.To address these challenges,this paper proposes a Text-Gated Interaction Network with Inter-Sample Commonality Perception(TGICP).Specifically,we utilize a Inter-sample Commonality Perception(ICP)module to extract common features from similar samples within the same modality,and use these common features to enhance the original features of each modality,thereby obtaining a richer and more complete multimodal sentiment representation.Subsequently,in the cross-modal interaction stage,we design a Text-Gated Interaction(TGI)module,which is text-driven.By calculating the mutual information difference between the text modality and nonverbal modalities,the TGI module dynamically adjusts the influence of emotional information from the text modality on nonverbal modalities.This helps to reduce modality information asymmetry while enabling full cross-modal interaction.Experimental results show that the proposed model achieves outstanding performance on both the CMU-MOSI and CMU-MOSEI baseline multimodal sentiment analysis datasets,validating its effectiveness in emotion recognition tasks.

文摘University students,transitioning from adolescence to adulthood,are at a critical stage where dietary habits and health behaviors are established,influencing long-term health outcomes.This study aimed to assess the dietary intake and nutritional awareness of a population of Chinese university students(n=833),comparing their consumption with national dietary guidelines and reference intakes,while exploring subgroup differences.Results indicated that males had significantly higher amounts of most food categories compared to females.Except for whole grains and legumes,ethnic minorities had lower compliance with the recommended intakes for several food categories compared to Han Chinese.Han males consumed more energy,protein,and fat than their ethnic minority counterparts.Obese participants showed higher protein and fat intake compared to those with normal body mass index(BMI).Additionally,BMI-related trends in macronutrient contributions showed that protein and fat contributed more to the total energy intake of individuals with higher BMI.Han individuals also had higher energy contributions from protein and fat and lower carbohydrate contributions compared to ethnic minorities.Nutrient intake was generally below recommended levels,with low proportions of participants meeting the recommended intake for vitamin A,C,calcium and dietary fiber.High proportions of participants exceeded the tolerable upper intake levels for iron and manganese.Nutritional awareness scores were also significantly higher among Han students,as well as those with higher BMIs and higher income levels.This study highlights significant disparities in dietary intake and nutritional awareness among Chinese university students,with variations across sex,ethnicity,BMI,and income categories.
