This paper proposes an innovative methodology for geospatial forecasting of electrical demand across various consumption segments and scales, integrating machine learning discrete convolution within the framework global system projections. The study was conducted in two phases: first, techniques were utilized to classify determine relative growth with similar patterns. In second phase, methods employed produce accurate spatial forecasts by incorporating influence neighboring areas through a...

We present a model based on the implication of an exceptional ${E}_{6}$-GUT symmetry for anomalous magnetic moment muon. follow particular chain breakings with Higgses in $\mathbf{78}$ and $\mathbf{351}$ representations. analyze radiative correction contributions to muon mass effects breaking so-called Weinberg symmetry. also estimate range values parameters our model.

The scattering and capture of right-handed neutrinos by an Abelian cosmic string in the SO(10) grand unification model are considered. cross section per unit length due to interaction with gauge Higgs fields is much larger its scaling regime than friction because infrared cutoff former. probability a zero mode accompanied emission or boson shows resonant peak for neutrino momentum order mass. Due decrease number strings comoving volume epoch, cosmological consequences superconducting formed...

Supersymmetry breaking of a supersymmetric harmonic oscillator with polynomial interaction is analyzed. Some thermal effects are studied in the context Thermo Field Dynamics (TFD). The restored supersymmetry results non vanishing energy at finite temperatures due additivity effects, while $T=0$ zero.

In this letter, we reconsider the delicate issue of symmetry and supersymmetry breakings for gauge theories with gauge-field mixings. The purpose is to study generalyzed potentials in presence more than a single potential. work, following stream investigation on supersymmetric without flat directions, contemplate possibility building up D- F-term by means mixing connection U(1)x U(1)' -symmetry. We investigate generalized potential including an N=1 extension Maxwell-Chern-Simons model...

The M\"ossbauer spectroscopy is presented as an alternative experimental technique to be pursued in the detec-tion of Coherent Elastic{\nu}-Nucleus Scattering (CENNS). neutrino transferred energy neutrino-nucleusinteraction causes a perturbation at nuclear levels which are responsible for gamma radiation M\"ossbauerresonance. main characteristic recoil less condition imposed on nucleiimposed by quantum restrictions crystalline array potential. scattering expected tooccurs low regime beam,...

Violation of chiral symmetry together with change mass sign allows a linear correction in inverse power new physics scale to the anomalous magnetic moment muon. In this light we analyse alternative models showing particular that grand unification, supersymmetry and muon substructure may explain discrepancy between experimental value anomaly standard model calculation.
