The real part of the relative permittivity \({\varepsilon }{\prime}\left(\omega \right)\) is related to the energy stored due to polarization, and the imaginary part \(\varepsilon {\prime}{\prime}(\omega )\) is related to the dielectric loss due to conduction [40]. Variation of \...
When I calculate the smooth L1 Loss between two Variable with F.smooth_l1_loss(x, y, reduce=False), I will the get this: However, when switching to nn.SmoothL1Loss(x, y, reduce=False), I have no problem. It's weird man
Indeed, the gain in energy obtained from a weak O–O bond (∼35 kcal mol− 1) deriving from the dimerization is lower than the loss of the resonance energy of the two aminoxyl groups. Interestingly, nitroxide stability is strongly affected by the nature of the adjacent group attached ...
The mass loss of the title compound was recorded as a function of temperature in air between 25°C and 800°C at a heating rate of 5°C/min. A constant air flow of 30 cm3 min−1 was maintained during the experiment. Absorption spectra The absorption spectra were recorded in methanol ...
Activation enthalpy (∆H) and activation entropy (∆S) were calculated for the activation complex formation in the transition state relation using The transition state is expressed in Eq. (15): the experimental values of the CR from the weight loss results. Scientific Reports | (2023) 13...
formed a number of highly localized binary and/or ternary compositions with a melting point in the sintering temperature range. The nominal compositions underwent variation due to a loss of the constituent elements by localized melting and partial leakage of the melt from the mold during sintering....
These diseases often start between 45 and 70 years of age, where they belong to the class of psychotic disorders. Alzheimer's manifests in the progressive loss of mental function (Alzheimer's Association, 2015). While, Parkinson is a chronic degenerative neurological disease that affects the ...
In this case, Δm, S, w, winh and t correspond respectively to average weight loss, sample working area (cm²), corrosion rates in 1 M HCl environment, corrosion rates in the presence of the imidazole derivative and soaking time (6 h). 2.4. Electrochemical investigation Electrochemica...
