Using Excel Spreadsheet to Understand the Limiting Value of a Sequence Abstract

open access: yes, 2003
Problems involving sequences and series are rarely common in science and mathematics subjects. Especially for students to find the limiting value of a sequence, in other words to determine the convergence or divergence of a sequence, is still a confusing

Effects of environmental change on genetic diversity and distribution pf phelbotomus ariasi, a vector of visceral leishmaniasis in Southwest Europe [PDF]

open access: yes
Leishmania infantum is the causative agent of zoonotic visceral leishmaniasis (ZVL) in the Mediterranean region, with the domestic dog as the main reservoir host. Phlebotomus (Larroussius) ariasi is the principal vector in cooler, forested ecotopes in

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

open access: yesAdvanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Bias Reduction and Filter Convergence for Long Range Stereo

open access: yes, 2005
We are concerned here with improving long range stereo by filtering image sequences. Traditionally, measurement errors from stereo camera systems have been approximated as 3-D Gaussians, where the mean is derived by triangulation and the covariance by ...

The extent of homoplasy in the trunk and forelimb of the hominoidea [PDF]

open access: yes, 2002
For the last century, palaeoprimatologists have questioned whether extant hominoids acquired their hunk and forelimb adaptations (previously interpreted as correlated with forelimb suspension) from a common ancestor, or developed them independently ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...
