Evaluating the Impact of Nano-Silica and Silica Hydrogel Amendments on Soil Water Retention and Crop Yield in Rice and Clover Under Variable Irrigation Conditions by Mohamed A. Abd El-Aziz, Mohssen Elbagory, Ahmed A. Arafat, Hesham M. Aboelsoud, Sahar El-Nahrawy, Tamer H. Khalifa, Alaa El-Dein Omara

“…So, this study evaluates the impact of silica and nano-silica hydrogels on soil water retention, crop yield, and crop water productivity under variable irrigation regimes. Using a randomized complete block design with furrow irrigation, the experiment tested different hydrogel application rates and irrigation levels in rice (<i>Oryza sativa</i> L.) and clover (<i>Trifolium alexandrinum</i> L.) across two growing seasons. …”

Forecast generation model of municipal solid waste using multiple linear regression by J.A. Araiza-Aguilar, M.N. Rojas-Valencia, R.A. Aguilar-Vera

“…Initially, different regression models were generated, but only 2 of them were considered useful, because they used few predictors that were statistically significant. The most important variables to predict the rate of waste generation in the study area were the population of each municipality, the migration and the population density. …”

Depth-specific soil moisture estimation in vegetated corn fields using a canopy-informed model: A fusion of RGB-thermal drone data and machine learning by Milad Vahidi, Sanaz Shafian, William Hunter Frame

“…Sophisticated regression models such as Gradient Boosting Machines (GBM), Least Absolute Shrinkage and Selection Operator (Lasso), and Support Vector Machines (SVM) were employed to analyze the effects of spectral indices, land surface temperature (LST), and structural canopy variables on soil moisture estimation accuracy. Our results reveal that thermal variables, particularly LST, exhibit significant correlations with soil moisture at shallower depths, especially in non-irrigated plots where moisture variability tends to be greater. …”

Effect of R-phase on shape recovery speed of Ti-Ni shape memory alloy wire for variable-stiffness mechanism using jamming transition phenomenon by Naoki MATSUMOTO, Hiroki CHO, Kazuto TAKASHIMA, Hidetaka SUZUKI

“…The jamming transition phenomenon refers to the change in stiffness of a powder as its density changes. As a familiar example, vacuum-packed coffee grounds are hard, but when opened to allow air into the package and the density is reduced, the grounds become softer. …”

PKS J0805-0111: A Second Owens Valley Radio Observatory Blazar Showing Highly Significant Sinusoidal Radio Variability—The Tip of the Iceberg by P. V. de la Parra, S. Kiehlmann, P. Mróz, A. C. S. Readhead, A. Synani, M. C. Begelman, R. D. Blandford, Y. Ding, F. Harrison, I. Liodakis, W. Max-Moerbeck, V. Pavlidou, R. Reeves, M. Vallisneri, M. F. Aller, M. J. Graham, T. Hovatta, C. R. Lawrence, T. J. W. Lazio, A. A. Mahabal, B. Molina, S. O’Neill, T. J. Pearson, V. Ravi, K. Tassis, J. A. Zensus

“…To estimate the significance of the sinusoidal variations, we generate 10 ^6 simulated light curves that reproduce the radio variability characteristics of PKS J0805−0111 and show that the global probability that the periodicity we detect is due to the red-noise tail of the power spectral density is p = 6.7 × 10 ^−5 (3.82 σ ). …”
