This study analyzes the nonlinear optical properties exhibited by graphene, focusing on absorption coefficient and refractive index. The evaluation was conducted using Z-scan technique with a 532 nm wavelength laser at various intensities. index were measured. Four machine learning models, including linear regression, decision trees, random forests, gradient boosting trained to analyze how varies variables such as spot radius, maximum energy, normalized minimum transmission. models synthetic...
We study the static and dynamic properties of networks crumpled creases formed in hand crushed sheets paper. The fractal dimensionalities crumpling unfolded (flat) folded configurations are determined. Some other noteworthy features established. physical implications these findings discussed. Specifically, we state that self-avoiding interactions introduce a characteristic length scale sheet crumpling. A framework to model phenomena is suggested. Mechanics crushing under external confinement...
Detecting deficits in reading and writing literacy skills has been of great interest the scientific community to correlate executive functions with future academic skills. In present study, a prototype serious multimedia runner-type game was developed, Play SID, designed detect deficiencies cognitive abilities preschool children (sustained attention, memory, working visuospatial abilities, reaction time), before learning read write. Usability tests are used Human-Computer Interaction...
Current epilepsy rates in Mexico are 4% (SERSAME-Health Ministry), of which 80% correspond to Temporal Lobe Epilepsy (TLE). Antiepileptic drug administration is systemic, meaning that 90% the active agent lost between and delivery epileptic focus brain. Severe toxic secondary effects may occur as a result. The present study aimed at developing an alternative antiepileptic system. In this study, sol-gel nanostructured titania device, valproic acid (VPA) has been encapsulated. This...
We point out that the chemical space of a totally disconnected Cantor dust ${K}_{n}\ensuremath{\subset}{E}^{n}$ is compact metric ${C}^{n}$ with spectral dimension ${d}_{s}={d}_{\ensuremath{\ell}}=n>D$, where $D$ and ${d}_{\ensuremath{\ell}}=n$ are fractal dimensions ${K}_{n}$, respectively. Hence, we can define random walk in as Markovian Gaussian process. The mapping into defines quenched L\'evy flight on single step duration independent length. equations, describing superdiffusion...
Electrical and nonlinear optical properties exhibited by single-wall carbon nanotubes in thin film form were experimentally numerically analyzed. A vectorial two-wave mixing technique confirmed an inhomogeneous third-order response dependent on the orientation of sample explored nanosecond pulses at 532 nm wavelength. Electrochemical impedance spectroscopy measurements lead to evaluate conductivity capacitive response. Since electrical did not match comparative 2D regions integrated...
