Fluorination of 2-aminopyridines and pyridin-2(1 H)-ones in the presence Selectfluor, water, chloroform under mild conditions has been realized. This method gives fluorinated pyridines good to high yields with regioselectivities. The electron-deficient pyridine system is activated by an amino or hydroxyl group at C2. regioselectivity fluorination reaction strongly dependent upon substituent pattern 2-aminopyridine H)-one. transformation 3-fluoro-substituted derivative into zolimidine was...
Using LiCl/LiBr, Selectfluor-promoted chlorination/bromination of 2-aminopyridines and 2-aminodiazines is established, producing the corresponding products with high regioselectivity.
Abstract. Long-time serial observation of surface ice flow velocity in Antarctic is a crucial component estimating the mass balance sheet. However, there lack historical continental scale maps Antarctica before 1990s. Historical optical images such as ARGON and Landsat 1990s are difficult to be used for mapping, due fact that they mostly not strictly geo-processed (e.g., ortho-rectified) image quality lower than those recent sensors. This paper presents systematic framework developing map...
This paper presents an automated methodology for the accurate reconstruction of surfaces and 3D objects. method was developed close-range photogrammetric applications, with a particular attention to terrestrial free-form objects that can be modeled point clouds extracted from high resolution images. The image orientation phase is carried out using automatic procedure based on rigorous bundle adjustment. Then, approximate model obtained patch-based matching strategy. this initial refined...
Abstract. Recent research indicates that the estimated elevation changes and associated mass balance in East Antarctica are of some degree uncertainty; a light accumulation has occurred its vast inland regions, while loss Wilkes Land appears significant. It is necessary to study change trend context long period Antarctic Ice Sheet (EAIS). The input-output method based on surface ice flow velocity thickness one most important ways estimate balance, which can provide longer-term knowledge...
Abstract. Ice flow velocity is a vital parameter for estimating the ice mass balance of glaciers in Antarctica. Especially long time serial observation surface great significance to assessing relationship between Antarctic materials and global climate change. However, existing research on based remote sensing data since 1970s due harsh This paper presents an method includes image pre-processing, geometric model reconstruction, ortho-rectification feature matching by using ARGON images token...
Abstract. Models based on physical principles or semi-empirical parameterizations have used to compute the firn density, which is essential for study of surface processes in Antarctic ice sheet. However, parameterization snow density often challenged by description detailed local characterization. In this we propose generate a map East Antarctica from all filed observations that are available. Considering non-uniformly distributed around Antarctica, obtained different methods, and temporally...
New chiral sulfinamide ligands made from salicylic acids and tert-butanesulfinamide was utilized in Pd-catalyzed asymmetric allylic substitutions of ethyl 2-fluoroacetoacetate, which afforded the fluorinated allyl products with up to 98% yield, 94% ee, 2.2:1 dr. Both sulfoxide hydroxyl group on sulfanilamide are crucial for enantiocontrol alkylations 2-fluoroacetoacetate.
The idea of simulation analysis and multi-objective evaluation was applied in parameter optimization for business process. By analyzing the parameters business, four mainly optimal their corresponding problems were determined. Some indexes synthetically evaluating performance process given, which could provide choice criteria optimization. Aiming at characteristics multi-parameter process, a multi-layer iterate method based on Genetic Algorithm provided, layered disposal solution space...
Abstract. Ice flow velocity over long time series in East Antarctica plays a vital role estimating and predicting the mass balance of Antarctic Sheet its contribution to global sea level rise. However, there is no ice product with large space scale available showing pattern before 1990s. We proposed three methods including parallax decomposition, grid-based NCC image matching, feature gird-based matching constraints for estimation surface based on ARGON KH-5 LANDSAT imagery, feasibility...

The role of a motion planner is pivotal in quadrotor applications, yet existing methods often struggle to adapt complex environments, limiting their ability achieve fast, safe, and robust flight. In this letter, we introduce performance-enhanced designed for autonomous flight environments including dense obstacles, dynamic unknown disturbances. global generates an initial trajectory through kinodynamic path searching refines it using B-spline optimization. Subsequently, the local takes into...
Abstract. Antarctica is an important part of the earth system and crucial to global sea-level climate change. In 1995, a number US intelligence satellite photographs from 1960s 1970s have been declassified, only portion which (ARGON) covers Antarctica. It provides broader perspective study early it’s very for us changes in stage this paper, hierarchical stereo image matching strategy was used reconstruct digital elevation model Larsen B region Peninsula using ARGON images. The accuracy...
Abstract. Surface albedo, defined as the ratio of upward to downward solar irradiance, is an important climate parameter in surface energy budget. Among them, glacier albedo link between glaciers and hydration process cold zones, it also factor restricting development distributed energy-material balance model. Changes ice snow can alter entire geo-gas system cause local even global change. Glaciers High Mountain Asia have experienced heterogeneous rates loss since 1970s. The positive...
