Prediction of Daily Climate Using Long Short-Term Memory (LSTM) Model
Jinxin Xu, Zhuoyue Wang, Xinjin Li et al.|International Journal of Innovative Science and Research Technology (IJISRT)|2024
Cited by 973Open Access

Climaate prediction plays a vital role in various sectors, including agriculture, disaster management, and urban planning. Traditional methods for climate forecasting often rely on complex physical models, which require substantial computational resources and may not accurately capture local weather patterns. This study explores the potential of Long Short-Term Memory (LSTM) networks, a type of recurrent neural network, for predicting daily climate variables such as temperature, precipitation, and humidity. Utilizing historical climate data from the city of Delhi, we developed an LSTM model to forecast short-term climate trends. The model consists of two LSTM layers followed by three Dense layers and is compiled with the Adam optimizer, mean squared error loss, and mean absolute error as a metric. Our results demonstrate the model's capability to capture temporal dependencies in climate data, achieving a satisfactory level of accuracy in temperature forecasting. This research underscores the potential of machine learning techniques, particularly LSTM networks, in enhancing climate prediction and contributing to more informed decision-making in weather-sensitive sectors.

Copper-Mediated Trifluoromethylation Using Phenyl Trifluoromethyl Sulfoxide
Xinjin Li, Jingwei Zhao, Liang Zhang et al.|Organic Letters|2014

A new method for the generation of trifluoromethylcopper ("CuCF3") species from readily available phenyl trifluoromethyl sulfoxide has been developed. The "CuCF3" reagent can be applied in efficient trifluoromethylations of aryl iodides and activated aryl bromides in the absence of additional ligands. Furthermore, the "CuCF3" species can also undergo oxidative cross-coupling with terminal alkynes and arylboronic acids.

Radical (Phenylsulfonyl)difluoromethylation of Isocyanides with PhSO<sub>2</sub>CF<sub>2</sub>H under Transition-Metal-Free Conditions

Cited by 74

An atom-economical method for radical (phenylsulfonyl)difluoromethylation of isocyanides with PhSO2CF2H under transition-metal-free conditions has been developed. A PhSO2CF2 radical is generated through the oxidation of PhSO2CF2– after the deprotonation of PhSO2CF2H in one pot. The reaction exhibits excellent functional-group tolerance and the resulting products can be further modified with the removal of a PhSO2 group to give other CF2-containing compounds.

Bis(difluoromethyl)trimethylsilicate Anion: A Key Intermediate in Nucleophilic Difluoromethylation of Enolizable Ketones with Me<sub>3</sub>SiCF<sub>2</sub>H

A pentacoordinate bis(difluoromethyl)silicate anion, [Me3 Si(CF2 H)2 ](-) , is observed for the first time by the activation of Me3 SiCF2 H with a nucleophilic alkali-metal salt and 18-crown-6. Further study on its reactivity by tuning the countercation effect led to the discovery and development of an efficient, catalytic nucleophilic difluoromethylation of enolizable ketones with Me3 SiCF2 H by using a combination of CsF and 18-crown-6 as the initiation system. Mechanistic investigations demonstrate that [(18-crown-6)Cs](+) [Me3 Si(CF2 H)2 ](-) is a key intermediate in this catalytic reaction.
