摘要： This paper introduces how to use geometric figures to represent integers, and successfully proves Goldbach’s conjecture by using the mapping relationship between the internal angles of circles and sectors and the number of integers. It is also explained and proved that w(n) is the function that calculates the lower limit of the number of prime pairs. A very effective new method is found to solve this kind of integer problems.

摘要： Forsythiae Fructus,the fruit of Forsythia suspense is a traditional Chinese hebal medicine that has the antiviral and antioxidant effects in China.Modern analytical chemistry studies showed that the extracts of Forsythiae Fructus contain many bioactive components,such as flavonoids,lignans,phenolic acids,and terpenoids,which can be used to anti-inflammatory and treat toxicity,tonsillitis,ulcers,pharyngitis and acute nephritis.In order to study the types and quantities of metabolites in Forsythiae Fructus,we isolated,identified and analysed metabolites between two varieties of Forsythiae Fructus using UPLC/ESI-Q TRAP-MS/MS.The results showed that a total of 407 metabolites were identified in Forsythiae Fructus using UPLC/ESI-Q TRAP-MS/MS,including 21 terpenoids,68 phenolic acids,63 flavonoids,43 amino acids and derivatives,22 alkaloids,55 lipids,24 lignans and coumarins,31 nucleotides and derivatives,29 organic acids,and 51 other metabolites.Among,lignans and coumarins,terpenoids,organic acids,lipids,and phenolic acids were rich in Forsythiae Fructus,which accounted for more than 60%of the total metabolite content.Differential metabolite analysis revealed that 80 metabolites differed significantly between the two types of Forsythiae Fructus.Our results greatly enrich the Forsythiae Fructus phytochemical composition database and provide valuable information for further study of the metabolites of Forsythiae Fructus.

摘要： SUMMARY In many statistical applications,composite variables are constructed to reduce the number of variables and improve the performances of statistical analyses of these variables,especially when some of the variables are highly correlated.Principal component analysis(PCA)and factor analysis(FA)are generally used for such purposes.If the variables are used as explanatory or independent variables in linear regression analysis,partial least squares(PLS)regression is a better alternative.Unlike PCA and FA,PLS creates composite variables by also taking into account the response,or dependent variable,so that they have higher correlations with the response than composites from their PCA and FA counterparts.In this report,we provide an introduction to this useful approach and illustrate it with data from a real study.

摘要： Mangrove forests are vulnerably threatened by sea level rise(SLR).Vegetation organic carbon(OC)stocks are important for mangrove ecosystem carbon cycle.It is critical to understand how SLR affects vegetation OC stocks for evaluating mangrove blue carbon budget and global climate change.In this study,biomass accumulation and OC stocks of mangrove vegetation were compared among three 10 year-old Kandelia obovata(a common species in China)mangrove forests under three intertidal elevations through species-specific allometric equations.This study simulated mangrove forests with SLR values of 0 cm,40 cm and 80 cm,respectively,representing for the current,future~100 a and future~200 a SLR of mangrove forests along the Jiulong River Estuary,China.SLR directly decreased mangrove individual density and inhibited the growth of mangrove vegetation.The total vegetation biomasses were(12.86±0.95)kg/m^2,(7.97±0.90)kg/m^2 and(3.89±0.63)kg/m^2 at Sites SLR 0 cm,SLR40 cm and SLR 80 cm,respectively.The total vegetation OC stock decreased by approximately 3.85 kg/m^2(in terms of C)from Site SLR 0 cm to Site SLR 80 cm.Significantly lower vegetation biomass and OC stock of various components(stem,branch,leaf and root)were found at Site SLR 80 cm.Annual increments of vegetation biomass and OC stock also decreased with SLR increase.Moreover,significant lower sedimentation rate was found at Site SLR 80 cm.These indicated that SLR will decrease mangrove vegetation biomass and OC stock,which may reduce global blue carbon sink by mangroves,exacerbate global warming and give positive feedback to SLR.

摘要： In this paper, I show that the Special Relativistic effect of mass increase that occurs within objects when they move at high speed can be explained using Classical Physics principles. In my analysis, the wave nature of condensed matter and energy/mass equivalence are taken into consideration. The wave nature of particles is modelled as the particle structure comprising three-dimensional standing waves. When this is done, the difference in the energy sum of the component waves that comprise a particle moving at a high speed, when compared to those of a stationary particle, completely accounts for the mass increase. Furthermore, the additional momentum of the wave components in the direction of motion (the Longitudinal direction) is the cause of the inertia, or effective mass, of the object being greater than that in the Transverse direction (orthogonal to the direction of motion).

摘要： The research investigation was carried out in the experimental area of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207, during the late Rabi season Mid December to May 2018 to study the genetic variability and character association of yield components in Maize with 35 maize genotypes as experimental materials that were laid out in Randomized Complete Block Design (RCBD) with three replications. The research work was oriented to calculate and estimate the yield factor through analyzing the mean performances, variability, heritability, genetic advance, correlation coefficient and path analysis involving the yield contributing characters. The maximum yield per plant (117.51 g) was estimated in the genotype G12 (Pacific) and the minimum yield per plant (51.89 g) was recorded in the genotype G17 (Dekalb Super). The phenotypic coefficient of variation was observed higher than the genotypic coefficient of variation for all yield contributing characters. Heritability was also shown higher compared to genetic advance in comparative mean study for all the characters involved. Significant and positive correlation was observed for grain yield per plant with plant height (0.774), cob length (0.956), grain per row (0.703) and 100-seed weight (0.365). In path analysis study, positive direct correlation was recorded in days to male flowering (0.247), cob breadth (1.078), number of grains per cob (6.874) and 100-seed weight (0.595).

摘要： We consider a functional partially linear additive model that predicts a functional response by a scalar predictor and functional predictors. The B-spline and eigenbasis least squares estimator for both the parametric and the nonparametric components proposed. In the final of this paper, as a result, we got the variance decomposition of the model and establish the asymptotic convergence rate for estimator.

摘要： Hyperspectral images (HSI) have hundreds of bands, which impose heavy burden on data storage and transmission bandwidth. Quite a few compression techniques have been explored for HSI in the past decades. One high performing technique is the combination of principal component analysis (PCA) and JPEG-2000 (J2K). However, since there are several new compression codecs developed after J2K in the past 15 years, it is worthwhile to revisit this research area and investigate if there are better techniques for HSI compression. In this paper, we present some new results in HSI compression. We aim at perceptually lossless compression of HSI. Perceptually lossless means that the decompressed HSI data cube has a performance metric near 40 dBs in terms of peak-signal-to-noise ratio (PSNR) or human visual system (HVS) based metrics. The key idea is to compare several combinations of PCA and video/ image codecs. Three representative HSI data cubes were used in our studies. Four video/image codecs, including J2K, X264, X265, and Daala, have been investigated and four performance metrics were used in our comparative studies. Moreover, some alternative techniques such as video, split band, and PCA only approaches were also compared. It was observed that the combination of PCA and X264 yielded the best performance in terms of compression performance and computational complexity. In some cases, the PCA + X264 combination achieved more than 3 dBs than the PCA + J2K combination.

摘要： In this study, a total of 115,246 ground motions recorded during earthquakes of Moment magnitudes ranging from M_w 5.0 to M_w 9.0 are analyzed statistically. A total of 21 ground motion parameters characterising the recorded acceleration time histories are used in the analysis. Classification of these parameters through statistical correlation is reported and a parameter called "distance from zero-amplitude axis," or d_(Z-A), is formulated in the principal component space. The ability for d_(Z-A) to rate the damage potentials of strong motion records is evaluated through correlation of d_(Z-A) with Japan Meteorological Agency(JMA) instrumental seismic intensities. This parameter can be used to rate damage potential of any strong motion record irrespective of the magnitude and location of the earthquake. It can also be used in selecting ground motion records of appropriate damage potential in seismic design and probabilistic analysis.

摘要： Aim: To report a case of solitary, parietal lobe abscess in a boy, aged 16 years in Tetralogy of Fallot. Introduction: Infective endocarditis is a serious and fatal complication in congenital heart disease. Following bacterial endocarditis, ventricular septal defect (VSD) and Tetralogy of Fallot (TOF) have less morbidity and higher survival rate in children. Neurological complications were recognized in 20% of cases and brain abscess is a serious infection of brain parenchyma as a result of seeding of infective pathogens in the shunted blood from the right side of the heart. Case Report: A 16 year old boy had Tetralogy of Fallot, presented with altered sensorium of sudden onset. Echocardiography revealed a large vegetation, attached to the ventricular septum and a large VSD with overriding of aorta. CT brain revealed a large abscess cavity in the parietal lobe, which was evacuated by aspiration and treated with antibiotics. Conclusion: Any patient presented with altered sensorium in cyanotic congenital heart disease must be evaluated with CT scanning for brain abscess and also check hematocrit to rule out hyperviscosity syndrome. Lumbar puncture has been considered hazardous in patients with brain abscess and usually performed under a strong suspicion of meningitis or ventriculitis in the absence of increased intracranial pressure.
