We investigated the differential impacts of a new Twitter-based Market Uncertainty index (TMU) and variables for Bitcoin before during COVID-19 pandemic. Results showed that TMU is leading indicator returns only pandemic, effect on Bitcoin’s conditional volatility significantly greater Furthermore, uncertainty content people’s tweets impacted by highly salient market. Taken together, our result...

Machine Learning is a booming technology today. In machine learning set of training, data to be provided the model for training and that predicts output. models are trained using computer program known as ML algorithms.The new learning-based Transition Metric Unit (TMU) 4D- 8PSK Trellis coded Modulation TCM Decoder presented in this work. The classic Viterbi decoder's branch metric unit, or TMU...

We used three techniques of precooling to test the hypothesis that heat strain would be alleviated, muscle temperature (Tmu) would be reduced, and as a result there would be delayed decrements in peak power output (PPO) during exercise in hot, humid conditions. Twelve male team-sport players completed four cycling intermittent sprint protocols (CISP). Each CISP consisted of twenty 2-min periods...

Usually, when connexion requests are added or removed from a network, for instance a WDM network, the routing of older connexions is not modified. Hence it is likely that after some additions and removings, the overall use of resources is far from optimal. In particular, a new request may be rejected, even if it could be added up to a whole rerouting of older requests. So operators have to reor...

Titration Raman spectroscopy has been developed for studying the solvation structure of metal ions in solution. The method affords us the solvation number, and the value thus obtained in neat solvents is in good agreement with that determined by EXAFS. The method is then applied to solvent mixtures, and the individual solvation number for each solvent is extracted. In a solvent mixture of N,N-d...

TMU-10 treated at 300 °C under air efficiently promotes H 2 generation ambient temperature from NaBH 4 . The enhanced catalytic activity derives a higher density of Lewis acid sites and the mesoporosity.
