Drying and storage of Piptadenia gonoacantha (Mart.) J.F.Macbr. seeds.
Braz J Biol
January 2025
Embrapa Agrobiologia, Seropédica, RJ, Brasil.
The objective was to evaluate the sensitivity of Piptadenia gonoacantha seeds to desiccation and storage conditions. The seeds were subjected to artificial drying in a forced air convection oven (39.7 °C ± 0.

In this study, we report the modification of a monolithic γ-aluminum oxy-hydroxide (γ-AlOOH) aerogel with cellulose nanofibers (CNFs) using the sol-gel method via supercritical drying. The optimized 2% CNF (w/w) results in a monolithic CNF-γ-AlOOH that is amorphous in nature, along with C-C and C-O-C functional groups. Transmission electron microscopy (TEM) images of the as-synthesized CNF-γ-AlOOH showed CNF embedded in the γ-AlOOH aerogel.

Tissue-specific endothelial cells (ECs) are critical for the homeostasis of pancreatic islets and most other tissues. In vitro recapitulation of islet biology and therapeutic islet transplantation both require adequate vascularization, which remains a challenge. Using human reprogrammed vascular ECs (R-VECs), human islets were functionally vascularized in vitro, demonstrating responsive, dynamic glucose-stimulated insulin secretion and Ca influx.

VST Centre for Glaucoma Care, L V Prasad Eye Institute, Kallam Anji Reddy Campus, Hyderabad, India.
Purpose: To evaluate intermediate-term outcomes and complications associated with Ahmed glaucoma valve (AGV) implantation in eyes with type 1 keratoprosthesis (KPro).
Methods: We retrospectively reviewed records of 43 eyes of 43 Indian patients with type 1 KPro and AGV from 2009 to 2021 with a minimum of 6-months of follow-up. Five eyes that had AGV before KPro were excluded, leaving 38 eyes for analysis.
Tensor Network Computations That Capture Strict Variationality, Volume Law Behavior, and the Efficient Representation of Neural Network States.

California Institute of Technology, Division of Chemistry and Chemical Engineering, Pasadena, California 91125, USA.
We introduce a change of perspective on tensor network states that is defined by the computational graph of the contraction of an amplitude. The resulting class of states, which we refer to as tensor network functions, inherit the conceptual advantages of tensor network states while removing computational restrictions arising from the need to converge approximate contractions. We use tensor network functions to compute strict variational estimates of the energy on loopy graphs, analyze their expressive power for ground states, show that we can capture aspects of volume law time evolution, and provide a mapping of general feed-forward neural nets onto efficient tensor network functions.
