Fornax
Fornax, Latin for "furnace," is a small and faint constellation located in the southern celestial hemisphere. Despite its modest size, Fornax is home to several notable deep-sky objects, including the Fornax Cluster of galaxies. French astronomer Nicolas Louis de Lacaille bestowed the name "Fornax" upon this constellation in 1756, and it is now recognized as one of the 88 modern constellations.

Hierarchical Nanobiosensors
Nanostructures have played a key role in the development of different techniques to attack severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some applications include masks, vaccines, and biosensors. The latter are of great interest for detecting diseases since some of their features allowed us to find specific markers in secretion samples such as saliva, blood, and even tears.

Circadian Regulation of Apolipoproteins in the Brain
The circadian rhythm is a 24 h internal clock within the body that regulates various factors, including sleep, body temperature, and hormone secretion. Circadian rhythm disruption is an important risk factor for many diseases including neurodegenerative illnesses. The central and peripheral oscillators’ circadian clock network controls the circadian rhythm in mammals. The clock genes govern the central clock in the suprachiasmatic nucleus (SCN) of the brain.

Navigation of Mobile Robot
Mobile robot navigation is a study area with several potential applications, both military and nonmilitary. Nonetheless, a great deal of problems remain, and many of them will probably need to be addressed using either a novel theory or another approach. The autonomous navigation of mobile robots has been studied by several researchers. Robots may encounter static interior environments or dynamic environments that change swiftly. The mobile robot’s goals may include reaching a particular place, following a predetermined course, or mapping out a space for later use. Many studies have been conducted throughout the world regarding this. Different methodologies were proposed on this topic, each with its advantages and disadvantages based on the recursive research. Navigation of a mobile robot involves determining the robot’s trajectory through an environment to reach a desired goal location while avoiding obstacles.

Photonic Bound States in the Continuum in Nanostructures
Bound states in the continuum (BIC) have garnered considerable attention recently for their unique capacity to confine electromagnetic waves within an open or non-Hermitian system. Utilizing a variety of light confinement mechanisms, nanostructures can achieve ultra-high quality factors and intense field localization with BIC, offering advantages such as long-living resonance modes, adaptable light control, and enhanced light-matter interactions, paving the way for innovative developments in photonics.

Equuleus
Equuleus, Latin for "the little horse," is one of the 88 modern constellations recognized by the International Astronomical Union. Despite its small size and dim stars, Equuleus holds historical significance, dating back to ancient times when it was known as a separate constellation or asterism. Today, it remains a subtle yet intriguing feature of the night sky, nestled between the larger constellations of Pegasus and Delphinus.

Fine-Structure Classification of Solar Metric Radio Bursts
Radio bursts provide important diagnostics of energetic phenomena of the Sun. In particular, bursts in decimetric and metric wavelengths probe the physical conditions and the energy release processes in the low corona as well as their association with heliospheric phenomena. The advent of spectral radio data with high time and high frequency resolution has provided a wealth of information on phenomena of short duration and narrow bandwidth. Of particular value are spectral data combined with imaging observations at specific frequencies.
