Hybrid mean value involving some two-term exponential sums and fourth Gauss sums

open access: yesElectronic Research Archive
Let $ q\ge3 $ be a positive integer. For any integers $ m $, $ n $, $ k $, $ h $, the two-term exponential sums $ C(m, n, k, h; q) $ is defined as $ C(m, n, k, h;q) = \sum\limits_{a = 1}^{q}e\left(\frac{ma^k+na^h}{q}\right) $, where $ k > h\ge 2 $.

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC

open access: yesAdvanced Electronic Materials, EarlyView.
A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.

On an uncertainty principle for small index subgroups of finite fields

open access: yesOpen Mathematics
In this article, we continue the study of the nonvanishing minors property initiated by Garcia, Karaali, and Katz, for the compressed Fourier matrix attached to a subgroup HH of the multiplicative group of a finite field Fq{{\mathbb{F}}}_{q} and a ...

Gauss Optics and Gauss Sum on an Optical Phenomena [PDF]

open access: yesFoundations of Physics, 2008
In the previous article (Found Phys. Lett. {\bf{16}} 325-341), we showed that a reciprocity of the Gauss sums is connected with the wave and particle complementary. In this article, we revise the previous investigation by considering a relation between the Gauss optics and the Gauss sum based upon the recent studies of the Weil representation for a ...

Inner topological structure of Hopf invariant

open access: yes, 2007
In light of $\phi$-mapping topological current theory, the inner topological structure of Hopf invariant is investigated. It is revealed that Hopf invariant is just the winding number of Gauss mapping.

Electrode‐Engineered Dual‐Mode Multifunctional Lead‐Free Perovskite Optoelectronic Memristors for Neuromorphic Computing

open access: yesAdvanced Electronic Materials, EarlyView.
A lead‐free perovskite memristive solar cell structure that call emulate both synaptic and neuronal functions controlled by light and electric fields depending on top electrode type. ABSTRACT Memristive devices based on halide perovskites hold strong promise to provide energy‐efficient systems for the Internet of Things (IoT); however, lead (Pb ...

The Effect of Magnetizing Irrigation Water on the Infiltration Rate in Soil

open access: yesTikrit Journal of Engineering Sciences, 2013
Many Modern researches indicate that we can obtain many positive effects on water when it is exposed to magnetic fields and effects on sum water properties.

Local Units Modulo Gauss Sums

open access: yesJournal of Number Theory, 1998
For a number field \(k\) and a prime number \(p\), denote by \(k_\infty\) the cyclotomic \(\mathbb{Z}_p\)-extension of \(k\) with \(n\)-th layer \(k_n\), and by \(A_\infty\) the projective limit of the \(p\)-part of the ideal class group of \(k_n\) with respect to the relative norms.

Trump Tariffs 2.0: Assessing the Impacts on US Distilled Spirits Imports

open access: yesAgribusiness, EarlyView.
ABSTRACT The proposed 25% tariff on Mexico and Canada could have significant repercussions on US imports of distilled spirits. This study estimates US import demand across various spirit categories (e.g., tequila, whiskey) and assesses the potential impact of the proposed tariff.

Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.
