The competition among julia, python and r for leadership in data science and development

Wed, 08 Oct 2025 00:00:00 -0600

This study compares Julia, Python, and R programming languages in the context of data science and software development. By evaluating performance, libraries, community support, and licensing, through conducting speed tests —including matrix operations, data manipulation, and visualization— it was observed that Julia is the fastest in numerical computations, making it ideal for scientific computing, while Python offers a balanced solution, it is efficient in data processing and graphics, and features a robust ecosystem and a large online community. R stands out in statistical analysis and visualization but is slower in computationally intensive tasks.

In the field of web development, Python leads with mature frameworks such as Django and Flask, while the alternatives in R (Shiny) and Julia (Genie) have more limited reach. Additionally, licensing differs: Julia and Python use MIT and PSF licenses, respectively, which are flexible and suitable for commercial projects, whereas R uses the GPL license, which is more restrictive.

In conclusion, Python emerges as the most versatile option for general-purpose projects, Julia excels in high-performance computing, and R maintains advantages in statistical analysis. Therefore, the choice of a programming language depends on the context and objectives of the project.

Nanoemulsions: Definition, synthesis methods, characterisation and biomedical applications

Wed, 08 Oct 2025 00:00:00 -0600

Nanoemulsions represent an emerging platform in controlled drug delivery due to their ability to transport and release bioactive compounds, improve their bioavailability, and enable sustained release at the site of action. Their nanometric size and high kinetic stability facilitate penetration into biological tissues and protect therapeutic molecules from enzymatic degradation. In the biomedical field, these nanostructures have shown great potential in the administration of hydrophobic agents and combination therapies. Growing scientific evidence supports their potential to revolutionise pharmaceutical delivery, although key barriers to their widespread clinical application remain. This paper is a brief summary presenting a description of nanoemulsions, the most commonly used synthesis methods and characterisation techniques. Finally, one of their many applications, controlled drug release, is demonstrated.

Implementation of a system for the study of pupillary reflexes using blue and white color stimuli.

Mon, 13 Oct 2025 00:00:00 -0600

This work describes the implementation of a video-oculography (VOG) and pupillometry system to measure pupillary reflexes in 20 volunteers (21 ± 3 years old) under blue and white light stimuli in a controlled environment. Although it's a very small sample, the results demonstrate that the system can be useful for obtaining pupillary data, with both the system and the infrastructure employed receiving a positive evaluation. Three 10 ms stimuli were used with 10 s intervals, recording pupillary areas between 3000 and 9000 pixels, with maximum contractions of 3000-5000 pixels. The results show that blue light induces slightly more pronounced contractions (average PCA: 444-449 pixels²) than white light (average PCA: 410-417 pixels²), with a decrease in post-illumination pupillary response (PIPR) in the third cycle due to fatigue of the intrinsically photosensitive retinal ganglion cells (ipRGCs). This system provides a preliminary database for future studies using artificial intelligence to identify potential biomarkers for parasympathetic ocular disorders.
