Solving Regularized Exp, Cosh and Sinh Regression Problems [PDF]

arXiv.org, 2023
In modern machine learning, attention computation is a fundamental task for training large language models such as Transformer, GPT-4 and ChatGPT. In this work, we study exponential regression problem which is inspired by the softmax/exp unit in the ...

Modified Exp-Function Method to Find Exact Solutions of Microtubules Nonlinear Dynamics Models

Symmetry, 2023
In this paper, we use the modified exp(−Ψ(θ))-function method to observe some of the solitary wave solutions for the microtubules (MTs). By treating the issues as nonlinear model partial differential equations describing microtubules, we were able to ...

Generalized Exp-Function Method to Find Closed Form Solutions of Nonlinear Dispersive Modified Benjamin–Bona–Mahony Equation Defined by Seismic Sea Waves

Mathematics, 2022
Using the new generalized exp-function method, we were able to derive significant novel closed form solutions to the nonlinear dispersive modified Benjamin–Bona–Mahony (DMBBM) equation. The general framework of the new generalized exp-function method has

Development of a soil exposure assessment for plant protection products in Brazil: Requirements, options, and recommendations

Integrated Environmental Assessment and Management, Volume 19, Issue 4, Page 862-869, July 2023., 2023
Abstract The Brazilian Environmental Authority (IBAMA) has recently identified soil organisms as a priority area for risk assessment development for plant protection products. This includes consideration of which species in soil fauna are important to be tested for risk assessment purposes, which ecotoxicological tests should be used, and which ...

The influence of sugarcane pre‐harvest fire on hantavirus prevalence in Neotropical small mammals

Ecosphere, Volume 13, Issue 9, September 2022., 2022
Abstract The use of pre‐harvest fire in sugarcane fields surprisingly results in an increase in the abundance of Neotropical Sigmodontinae rodents, which might carry hantavirus. By contrast, fire suspension induces a decline in rodents in the first 5 years.
