Fine tuning of the default depth and rate of ablation of the epithelium in customized trans-epithelial one-step superficial refractive excimer laser ablation

Purpose: To fine tune the default depth and rate of ablation of the epithelium in cTen~(TM) customized trans-epithelial one-step superficial refractive surgery by the comparison between the attempted post-operative ideal corneal shape and the achieved corneal shape. Methods: 88 consecutive eyes in 64 patients undergoing trans-epithelial superficial excimer ablation using the iVis laser Suite for either myopic/astigmatic or hyperopic/astigmatic refractive error. Each patient had at least 3 months of post-operative follow-up. Topographic examination of all eyes was carried out pre-operatively and at least 3 months post-operatively using the Precisio~(TM) surgical topographer. The comparison of these two measurements yielded values for depth, volumes and rates of ablated corneal tissue. By determining the different ablation rates of stroma and epithelium, a refinement of the depth of epithelium to be removed and a refinement of the stromal ablation were calculated. The mathematical model was applied on each one of the 88 clinical cases and the parameters for the fine tuning of the default depth and rate of ablation of the epithelium were determined using the least squares method. Results: The calculated pure stromal ablation rate was less than the average epithelium/stroma ablation rate used in planning the treatments by a factor of 0.96. The epithelial thickness predefined ablation assumption used to plan removal of the epithelium was adjusted considering the measured ablation and a radial adjustment function established for the fine tuning of the laser radial efficiency and allowing for the normal thickening of the epithelium in the peripheral cornea. From a clinical point of view, this methodology produces an improvement of the efficacy and a reduction of the variance of the clinical results. Conclusion: Comparison of accurately measured pre and postoperative topographies yields accurately established ablation rates of stroma and epithelium in trans-epithelial one step superficial ablation.
ST-Trader:A Spatial-Temporal Deep Neural Network for Modeling Stock Market Movement

Stocks that are fundamentally connected with each other tend to move together.Considering such common trends is believed to benefit stock movement forecasting tasks.However,such signals are not trivial to model because the connections among stocks are not physically presented and need to be estimated from volatile data.Motivated by this observation,we propose a framework that incorporates the inter-connection of firms to forecast stock prices.To effectively utilize a large set of fundamental features,we further design a novel pipeline.First,we use variational autoencoder(VAE)to reduce the dimension of stock fundamental information and then cluster stocks into a graph structure(fundamentally clustering).Second,a hybrid model of graph convolutional network and long-short term memory network(GCN-LSTM)with an adjacency graph matrix(learnt from VAE)is proposed for graph-structured stock market forecasting.Experiments on minute-level U.S.stock market data demonstrate that our model effectively captures both spatial and temporal signals and achieves superior improvement over baseline methods.The proposed model is promising for other applications in which there is a possible but hidden spatial dependency to improve time-series prediction.
Research on the invasive pest of fall armyworm(Spodoptera frugiperda)in China

The fall armyworm(Spodoptera frugiperda)is a major agricultural pest native to the Americas.It is widely distributed throughout the Western Hemisphere.It damages crops such as maize,wheat,rice,sorghum,cotton,herbage and various weeds,and reportedly feeds on more than 300 species(Montezano et al.2018).Fall armyworm is a typical lepidoptera pest and goes through four life stages:egg,larva,pupa and adult.Adults can lay eggs between 1 000 and 2 000 and complete a life cycle within about 30 days,reproducing at a fast speed.There are two biotypes of fall armyworm:Corn-biotype(C-strain)and Rice-biotype(R-strain).Both biotypes are widely distributed throughout the Americas.C-strain mainly feeds on maize,sorghum,sugarcane,wheat,and cotton plants,while R-strain mainly feeds on grass and rice plants(Murua et al.2015).They occasionally graze on plants in each other's host ranges.The two biotypes can be accurately identified using either TPI(Triose-Phosphate Isomerase)or COI(Cytochrome Oxidase Subunit I)molecular markers(Nagoshi et al.2012).In the Americas,fall armyworm is controlled mainly by chemical pesticides and Bt crops.Long-term use of chemical pesticides has resulted in widespread resistance,which has been reported throughout the Americas.Resistance to Bt crops has also recently been found,especially in South American countries.
Delineating the rice crop activities in Northeast China through regional parametric synthesis using satellite remote sensing timeseries data from 2000 to 2015

Accurate rice area extraction and yield simulations are important for understanding how national agricultural policies and environmental issues affect regional spatial changes in rice farming.In this study,an improved regional parametric syntheses approach,that is,the rice zoning adaptability criteria and dynamic harvest index(RZAC-DHI),was established,which can effectively simulate the rice cultivation area and yield at the municipal level.The RZAC was used to extract the rice area using Moderate Resolution Imaging Spectroradiometer time-series data and phenological information.The DHI was calculated independently,and then yield was obtained based on the DHI and net primary productivity(NPP).Based on the above results,we analyzed the spatial-temporal patterns of the rice cultivation area and yield in Northeast China(NEC)during 2000-2015.The results revealed that the methods established in this study can effectively support the yearly mapping of the rice area and yield in NEC,the average precisions of which exceed 90 and 80%,respectively.The rice planting areas are mainly located on the Sanjiang,Songnen and Liaohe plains,China,which are distributed along the Songhua and Liaohe rivers.The rice cultivation area and yield in this region increased significantly from 2000 to 2015,with increases of nearly 58 and 90%,respectively.The rice crop area and yield increased the fastest in Heilongjiang Province,China,whereas small changes occurred in Jilin and Liaoning provinces,China.Their gravity centers exhibited evident northward and eastward shifts,with offset distances of 107 and 358 km,respectively.Moreover,Heilongjiang Province has gradually become the new main rice production region.The methodologies used in this study provide a valuable reference for other related studies,and the spatial-temporal variation characteristics of the rice activities have raised new attention as to how these shifts affect national food security and resource allocation.
Developing a process-based and remote sensing driven crop yield model for maize(PRYM-Maize)and its validation over the Northeast China Plain

Spatial dynamics of crop yield provide useful information for improving the production.High sensitivity of crop growth models to uncertainties in input factors and parameters and relatively coarse parameterizations in conventional remote sensing(RS)approaches limited their applications over broad regions.In this study,a process-based and remote sensing driven crop yield model for maize(PRYM-Maize)was developed to estimate regional maize yield,and it was implemented using eight data-model coupling strategies(DMCSs)over the Northeast China Plain(NECP).Simulations under eight DMCSs were validated against the prefecture-level statistics(2010-2012)reported by National Bureau of Statistics of China,and inter-compared.The 3-year averaged result could give more robust estimate than the yearly simulation for maize yield over space.A 3-year averaged validation showed that prefecture-level estimates by PRYM-Maize under DMCS8,which coupled with the development stage(DVS)-based grain-filling algorithm and RS phenology information and leaf area index(LAI),had higher correlation(R,0.61)and smaller root mean standard error(RMSE,1.33 t ha~(-1))with the statistics than did PRYM-Maize under other DMCSs.The result also demonstrated that DVS-based grain-filling algorithm worked better for maize yield than did the harvest index(HI)-based method,and both RS phenology information and LAI worked for improving regional maize yield estimate.These results demonstrate that the developed PRYM-Maize under DMCS8 gives reasonable estimates for maize yield and provides scientific basis facilitating the understanding the spatial variations of maize yield over the NECP.
Transient cortical blindness in fat embolism syndrome-a diagnostic enigma

Fat embolism syndrome (FES) is a serious life-threatening manifestation of the fat embolism phenomenon characterized by Bergman's triad of dyspnea,petechiae and mental confusion.While fat embolization into systemic circulation is common,FES occurs in a meagre 0.05%-3% of patients having isolated long bone fractures.Though visual symptoms are commonly attributed to fat embolism retinopathy and is a later occurrence,it may not always be the case.Cortical blindness has been seldom reported in association with FES,and less so as a presenting complaint.Furthermore,no previous literature has described the same in context of an isolated tibia fracture.We report a 20-year-old gentleman with an isolated right tibia shaft fracture who developed sudden onset diminution of vision in both eyes less than 24 h following trauma with no other complaints.Lack of any remarkable ophthalmoscopic findings or other symptoms left us with a diagnostic conundrum.He later went on to develop altered mentation,hypoxia and generalized tonic-clonic seizures with subsequent MRI revealing multiple cerebral fat emboli also involving both occipital lobes.Supportive measures were instituted and his general condition as well as vision gradually improved following which he underwent plate fixation of the fracture under spinal anaesthesia.The perioperative period was uneventful and he was discharged following staple removal.At one month of follow-up,the patient had no residual visual field defects or neurological deficits.Though FES is rare among isolated tibia fractures,this clinical catastrophe may strike in any unsuspected setting thereby warranting a high index of suspicion to ensure early diagnosis and improved patient outcomes.
Bamboo Nodes of Vocal Fold-A Clinical Study of 14 Cases

Objective Bamboo node (BN) of vocal folds is a rare disease which is mostly associated with autoimmune diseases and always involves women as reported in literature.The purpose of this study is to investigate the clinical characteristics and the treatments in a series of BN cases.Methods We retrospectively collected and reviewed clinical information of all patients who presented bamboo nodes by fibreoptic laryngoscopy from 2011 to 2020 in our hospital,including the demographic information,clinical symptoms,associated autoimmune diseases,voice abuse,treatments,and outcomes.Patients were followed up periodically at clinics with fibreoptic laryngoscopy and/or voice recovery evaluation using the selfassessed voice visual analog scale (VAS).Results Totally 14 patients were diagnosed with BN and were included in the study.BN involved both women (8/14,57.1%) and men (6/14,42.9%).Bilateral lesions were found in 13 patients (92.9%).The most common symptom of BN was hoarseness (100%).Ten (71.4%) of 14 patients experienced voice abuse.Thirteen (92.9%) of them were concomitant with autoimmunity disease,and received medication therapy for the underlying autoimmune diseases;one patient received anti-acid treatment for the gastroesophageal reflux disease.Voice rests were performed in all patients.Voice recovered completely in 3 cases (21.4%),improved remarkably in 8 cases (57.1%),improved slightly in 1 case (7.1%),and no improvement in 2 cases (14.3%).Conclusions BNs are mostly associated with autoimmune disease and vocal abuse.It may occur in both females and males.Conservative treatment for the underlying autoimmune diseases and vocal rest are beneficial to voice recovery in most of the patients,and can be used as the first choice of treatment.
Design of activatable red-emissive assay for cysteine detection in aqueous medium with aggregation induced emission characteristics

A novel water-soluble red-emissive AIE fluorescence probe for cysteine (Cys) in situ was prepared and the performance of selectivity and sensitivity has been carefully investigated in this study. The probe was established on the electrostatic interaction of sulfonate functionalized tetraphenylethene (TPE) and polycation generated by the reaction between a polymer bearing dinitrobenzenesulfonate groups and Cys. From the experimental results, it was easy to distinguish Cys from glutathione (GSH) and homocysteine (Hcy) with a detection limit of 73 nmol/L. The assay system also possessed strong antiinterference ability against multitudinous amino acids. The Stokes shift was 142 nm and the emission ranged from 550 nm to 850 nm. In addition, double responses in fluorescence and ultraviolet-visible spectra also make the red-emissive assay ideal for sensitive detection and quantification of Cys for most purposes, especially in-situ monitoring of Cys in aqueous medium.
Support and Positioning Mechanism of a Detection Robot inside a Spherical Tank

Large pressure equipment needs to be tested regularly to ensure safe operation;wall-climbing robots can carry the necessary tools to inspect spherical tanks,such as cameras and non-destructive testing equipment.However,a wall-climbing robot inside a spherical tank cannot be accurately positioned owing to the particularity of the spherical tank structure.This paper proposes a passive support and positioning mechanism fixed in a spherical tank to improve the adsorption capacity and positioning accuracy of the inspection robot.The main body of the mechanism was designed as a truss composed of carbon fiber telescopic rods and can work in spherical tanks with diameters of 4.6–15.7 m.The structural strength,stiffness,and stability of the mechanism are analyzed via force and deformation simulations.By constructing a mathematical model of the support and positioning mechanism,the influence of structural deformation on the supporting capacity is analyzed and calculated.The robot positioning method based on the support and positioning mechanism can effectively locate the robot inside a spherical tank.Experiments verified the support performance and robot positioning accuracy of the mechanism.This research proposes an auxiliary support and positioning mechanism for a detection robot inside a spherical tank,which can effectively improve the positioning accuracy of the robot and meet the robotic inspection requirements.

A new ligand [1-{2-(2-pyridyl)-benzo[d]imidazole}-2-(5-hydroxyisophthalic acid) ethane] was used to synthesize cadmium and cobalt based florescent organic frameworks successfully under solvothermal conditions.Single-crystal X-ray crystallography of both complexes as well as their thermal stability and luminescence properties was investigated.Much emphasis was placed on the newly synthesized Cd-complex which shows great sensitivity for the detection of Fe~(3+) ions and could be used as a potential probe to detect the Fe~(3+) ions.
A buried submarine canyon in the northwestern South China Sea: architecture, development processes and implications for hydrocarbon exploration

High-resolution multichannel seismic data enables the discovery of a previous, undocumented submarine canyon (Huaguang Canyon) in the Qiongdongnan Basin, northwestern South China Sea. The Huaguang Canyon with a NW orientation is 140 km in length, and 2.5 km to 5 km in width in its upper reach and 4.6 km to 9.5 km in width in its lower reach. The head of the Huaguang Canyon is close to the Xisha carbonate platform and its tail is adjacent to the Central Canyon. This buried submarine canyon is formed by gravity flows from the Xisha carbonate platform when the sea level dropped in the early stage of the late Miocene (around 10.5 Ma). The internal architecture of the Huaguang Canyon is mainly characterized by high amplitude reflections, indicating that this ancient submarine canyon was filled with coarse-grained sediments. The sediment was principally scourced from the Xisha carbonate platform. In contrast to other buried large-scale submarine canyons (Central Canyon and Zhongjian Canyon) in the Qiongdongnan Basin, the Huaguang Canyon displays later formation time, smaller width and length, and single sediment supply. The coarse-grained deposits within the Huaguang Canyon provide a good environment for reserving oil and gas, and the muddy fillings in the Huaguang Canyon have been identified as regional caps. Therefore, the Huaguang Canyon is a potential area for future hydrocarbon exploration in the northwestern South China Sea. The result of this paper may contribute to a better understanding of the evolution of submarine canyons formed in carbonate environment.
An insight into shallow gas hydrates in the Dongsha area, South China Sea

Previous studies of gas hydrate in the Dongsha area mainly focused on the deep-seated gas hydrates that have a high energy potential, but cared little about the shallow gas hydrates occurrences. Shallow gas hydrates have been confirmed by drill cores at three sites (GMGS2 08, GMGS2 09 and GMGS2 16) during the GMGS2 cruise, which occur as veins, blocky nodules or massive layers, at 8-30 m below the seafloor. Gas chimneys and faults observed on the seismic sections are the two main fluid migration pathways. The deep-seated gas hydrate and the shallow hydrate-bearing sediments are two main seals for the migrating gas. The occurrences of shallow gas hydrates are mainly controlled by the migration of fluid along shallow faults and the presence of deep-seated gas hydrates. Active gas leakage is taking place at a relatively high-flux state through the vent structures identified on the geophysical data at the seafloor, although without resulting in gas plumes easily detectable by acoustic methods. The presence of strong reflections on the high-resolution seismic profiles and dim or chaotic layers in the subbottom profiles are most likely good indicators of shallow gas hydrates in the Dongsha area. Active cold seeps, indicated by either gas plume or seepage vent, can also be used as indicators for neighboring shallow gas hydrates and the gas hydrate system that is highly dynamic in the Dongsha area.
Discover the Post-Translational Modification Proteome Using Mass Spectrometry

Protein post-translational modifications (PTMs) are chemical modifications on proteins.PTMs play a key role in many cellular processes by influencing the structure of proteins and dynamically regulating their functions.Therefore,characterizing PTMs at proteome level is critical to provide invaluable insight into the functions of proteins underlying different biological processes.Advances in modern proteomics technologies including sample preparation,chromatography separation as well as mass spectrometry have propelled the PTMs proteome to further depths.During the past decade,to better examine the PTMs with high sensitivity and selectivity,our group have developed a series of MS-based novel analytical approaches to study the protein PTMs.Herein,we mainly introduce these approaches developed by our group and discuss how to overcome the technical obstacles of studying various protein PTMs with mass spectrometry.

窒息相关案件的死因纠错分析3例

导致死亡发生的疾病、暴力或衰老等因素即为死亡原因,简称“死因”。确定死因是法医病理学的首要任务,然而在法医实践中,死因鉴定错误时有发生[1],造成不良社会影响[2-3]。对于死因鉴定错误的案例,国内外以个案报道为主,缺乏对鉴定错误成因的系统分析。机械性窒息是法医实践中常见的死因,尸体征象表现为颜面部发绀、瘀点性出血和器官淤血等,称为窒息征象。其不具有特异性,不同尸体变化较大,与窒息相关的案例容易产生误判。
