On the crossing of the energy levels of a parameter-dependent quantum-mechanical Hamiltonian
(Springer, 2014-07-17)
The non-crossing rule for the energy levels of a parameter-dependent Hamiltonian is revisited and a flaw in a commonly accepted proof is revealed. Some aspects of avoided crossings are illustrated by means of simple models. ...
Speckle Noise Reduction in Ultrasound Imaging using the Key Points in Low Degree Unbiased FIR Filters
(2012-08-31)
In this paper we present a method of reducing speckle noise in applications for ultrasound image processing using low degree unbiased FIR filters.
An important feature of the p-lag gain of unbiased FIR filters is that at ...
Technological and Protein Residue Analysis on Ancient Stemmed Projectile Points of the Southern Andes Highlands
(2024)
We present the results of technological and protein residue analyses of the lithic assemblagesrecovered at the Pedernales-38 site (26.5°S; 69°W), located in the highlands of the southernAndes (3380 masl). Based on a ...
Crossing points in specific-heat curves of the asymmetric Hubbard model

SPICE Simulation of RRAM-Based Cross-Point Arrays Using the Dynamic Memdiode Model
(Frontiers Media, 2021-09)
We thoroughly investigate the performance of the Dynamic Memdiode Model (DMM) when used for simulating the synaptic weights in large RRAM-based cross-point arrays (CPA) intended for neuromorphic computing. The DMM is in ...
Culturally responsive ICT integration into teaching and learning [PowerPoint]
(2014-08-07)
This presentation notes the limited local digitized curriculum content in the Caribbean as opposed to the proliferation and easy access of US digital educational resources. It also notes that appropriate adaptation is ...
Application of the quasi-static memdiode model in cross-point arrays for large dataset pattern recognition
(Institute of Electrical and Electronics Engineers, 2019-11)
We investigate the use and performance of the quasi-static memdiode model (QMM) when incorporated into large cross-point arrays intended for pattern classification tasks. Following Chua's memristive devices theory, the QMM ...
Sensitivity and specificity of cutoff points of resting heart rate from 6,794 brazilian adolescents: A cross-sectional study
(2021-01-01)
Background: Resting heart rate (RHR) may be a useful screening tool for cardiovascular risk. However, RHR cutoff points, an interesting clinical approach, have never been described in young populations. Objective: To ...
