ANÁLISE MULTIVARIADA DE IMAGENS NA QUÍMICA: UM EXPERIMENTO PARA DETERMINAÇÃO DO pH DE ÁGUAS POTÁVEIS

Química Nova, 2015
A Multivariate Image Analysis (MIA) laboratory activity was proposed estimating pH of drinking water samples from its digital images after adding bromothymol blue as a pH indicator, and using the PLS multivariate calibration method.

Unraveling Microporosity in Hard Carbons: Insights Into Sustainable Sodium‐Ion Battery Materials

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
Hidden microporosity in hard‐carbon anodes for sodium‐ion batteries is revealed by small‐angle X‐ray scattering combined with Ruland–Smarsly analysis, including closed pores inaccessible to gas adsorption. Comparing petroleum‐derived and biowaste‐derived carbons links nanoscale disorder, surface area, and pore architecture to sodium storage ...

Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, Volume 37, Issue 13, Page 9038-9052, 15 August 2026.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

OctCarb—A GNU Octave Script for the Analysis and Evaluation of Wide-Angle Scattering Data of Non-Graphitic Carbons

C, 2022
We present a free software script operating in GNU Octave for the refinement of wide-angle X-ray and neutron scattering (WAXS/WANS) data of non-graphitic carbons (NGCs).

How Precise Is Predictive Coding for Things We Hear? Mismatch Negativity With Shepard Tones

European Journal of Neuroscience, Volume 64, Issue 1, July 2026.
MMN amplitudes to unpredictable tones in a discrete Shepard scale were more negative the farther the unpredictable tones were from the predicted note and more negative for tones that were less than the expected note. We conclude that the predictive model for a discrete Shepard scale has a sensitivity to tones less than one third of a semitone and is ...

Communication modeling using GNU Octave

, 2022
Mūsdienās komunikāciju sistēmas ir kļuvušas par neatņemamu sastāvdaļu cilvēku ikdienai, pētniecībai, kā arī citām nozarēm, un šādu sistēmu izstrāde pieprasa daudz laika un finansiālu resursu, tāpēc ir nepieciešams izplānot sistēmas projektējumu pirms tās

Voluntary Attention Selectively Modulates Omission Responses

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
Clapping sounds were occasionally omitted from a video (A). While early responses to omissions in the EEG showed similar amplitudes across conditions, larger responses were observed when attention was directed toward the auditory modality (D and E) compared to the visual modality (B and C).
