Palmprint Recognition
Palmprint recognition constitutes a pivotal biometric technology deployed in the identification and verification of individuals, relying on the distinctive patterns inherent in their palmprints. This method, known for its reliability and security, finds extensive applications in diverse fields, including access control, security systems, and forensic investigations. Palmprint image acquisition involves capturing high-quality palmprint images using various devices like cameras, scanners, or smartphones. These images are then subjected to preprocessing techniques, encompassing noise reduction, normalization, and enhancement, to ensure consistent submission despite any restrictions on the availability of materials and/or refined input data. Following preprocessing, relevant features are extracted, like minutiae points specific to an individual’s palm, ridges, and lines. These features are crucial for accurate identification and are obtained through advanced image processing methods.

Inorganic Nanoparticles for Cancer Treatment
The application of porphyrins and their derivatives have been investigated extensively over the past years for phototherapy cancer treatment. Phototherapeutic Porphyrins have the ability to generate high levels of reactive oxygen with a low dark toxicity and these properties have made them robust photosensitizing agents. In recent years, Porphyrins have been combined with various nanomaterials in order to improve their bio-distribution. These combinations allow for nanoparticles to enhance photodynamic therapy (PDT) cancer treatment and adding additional nanotheranostics (photothermal therapy—PTT) as well as enhance photodiagnosis (PDD) to the reaction. This review examines various porphyrin-based inorganic nanoparticles developed for phototherapy nanotheranostic cancer treatment over the last three years (2017 to 2020). Furthermore, current challenges in the development and future perspectives of porphyrin-based nanomedicines for cancer treatment are also highlighted.

Rhetoric of Technology
The rhetoric of technology is both an object and field of study. It refers to the ways in which makers and consumers of technology talk about and make decisions regarding technology and also the influence that technology has on discourse. Studies of the rhetoric of technology are interdisciplinary. Scholars in communication, media ecology, and science studies research the rhetoric of technology. Technical communication scholars are also concerned with the rhetoric of technology. The phrase "rhetoric of technology" gained prominence with rhetoricians in the 1970s, and the study developed in conjunction with interest in the rhetoric of science. However, scholars have worked to maintain a distinction between the two fields. Rhetoric of technology criticism addresses several issues related to technology and employs many concepts, including several from the canon of classical rhetoric, for example ethos, but the field has also adopted contemporary approaches, such as new materialism.

Associations of Linoleic Acid Intake and Chronic Disease
The intake of linoleic acid (LA) has increased dramatically in the standard American diet. LA is generally promoted as supporting human health, but there exists controversy regarding whether the amount of LA currently consumed in the standard American diet supports human health. While LA is considered to be an essential fatty acid and support health when consumed in modest amounts, an excessive intake of LA leads to the formation of oxidized linoleic acid metabolites (OXLAMs), impairments in mitochondrial function through suboptimal cardiolipin composition, and likely contributes to many chronic diseases that became an epidemic in the 20th century, and whose prevalence continues to increase. As LA consumption increases, the potential for OXLAM formation also increases. OXLAMs have been associated with various illnesses, including cardiovascular disease, cancer, and Alzheimer’s disease, among others. Lowering dietary LA intake can help reduce the production and accumulation of OXLAMs implicated in chronic diseases.

Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a serious neurodevelopmental disorder characterized by the impairment of the cognitive function of a child. Studies suggested that the intestinal microbiota has a critical role in the function and regulation of the central nervous system, neuroimmune system, and neuroendocrine system. Any adverse changes in the gut-brain axis may cause serious diseases. Food preferences and dietary patterns are considered as key influencing factors of ASD development. Several recent reviews narrated the importance of dietary composition on controlling or reducing the ASD symptoms. It has been known that consumption of probiotics confers several health benefits by positive amendment of gut microbiota. Influence of probiotic intervention in children with ASD have also been reported and it has been considered as an alternative and complementary therapeutic supplement for ASD. The present manuscript discussed the role of microbiota in the development of ASD.

MIP-Based Drug Delivery Systems
Despite the tremendous efforts made in the past decades, severe side/toxic effects and poor bioavailability still represent the main challenges that hinder the clinical translation of drug molecules. This has turned the attention of investigators towards drug delivery vehicles that provide a localized and controlled drug delivery. Molecularly imprinted polymers (MIPs) as novel and versatile drug delivery vehicles have been widely studied in recent years due to the advantages of selective recognition, enhanced drug loading, sustained release, and robustness in harsh conditions. This review highlights the design and development of strategies undertaken for MIPs used as drug delivery vehicles involving different drug delivery mechanisms, such as rate-programmed, stimuli-responsive and active targeting, published during the course of the past five years.

Gaspee Affair
Script error: No such module "Infobox military conflict". The Gaspee Affair was a significant event in the lead-up to the American Revolution. HMS Gaspee was a British customs schooner that had been enforcing the Navigation Acts in and around Newport, Rhode Island in 1772. It ran aground in shallow water while chasing the packet ship Hannah on June 9 near Gaspee Point in Warwick, Rhode Island. A group of men led by Abraham Whipple and John Brown attacked, boarded, and torched the ship. The event increased tensions between the American colonists and British officials, following the Boston Massacre in 1770. British officials in Rhode Island wanted to increase their control over trade—legitimate trade as well as smuggling—in order to increase their revenue from the small colony. But Rhode Islanders increasingly protested the Stamp Act, the Townshend Acts, and other British impositions that had clashed with the colony's history of rum manufacturing, maritime trade, and slave trading. This event and others in Narragansett Bay marked the first acts of violent uprising against the British crown's authority in America, preceding the Boston Tea Party by more than a year and moving the Thirteen Colonies as a whole toward the war for independence.

Gracchi
The Gracchi brothers, Tiberius and Gaius, were Romans who both served as tribunes of the plebs between 133 and 121 BC. They attempted to redistribute the occupation of the ager publicus— the public land hitherto controlled principally by aristocrats—to the urban poor and veterans, in addition to other social and constitutional reforms. After achieving some early success, both were assassinated by the Optimates, the conservative faction in the senate that opposed these reforms.

List of Canis Species and Subspecies
Canis, the genus of mammals commonly known as wolves, dingos, dogs, coyotes, and jackals, contains several living species, many divided into numerous subspecies, as well as numerous recently extinct and extinct prehistoric species. Domestic dogs are not usually granted taxonomic variety names below the level of either their species name, or subspecies name so they do not appear here with their popular breed names as individual entries. The New Guinea singing dog and any other varieties of subspecies appear as individual entries here when their taxonomic considerations now suggest that they are varieties of subspecies other than domestic dogs, such as of dingoes. References for taxonomic classification, issues, and current considerations, especially in light of DNA revelations year to year, are found in the articles on individual canids; as this article is only a list, the extensive literature and specifics of these issues for each canid are beyond the scope of reference notes here. Furthermore, articles on the species in this list's section headings, and details of their evolutionary, divergent, interbreeding, geolocational and human-culture mediated shifts contain references on which this list relies when including and positioning its entries. References to this article are thus of two sorts, those pertaining to wholesale sourcing of entries, especially those that do not yet have their own Wikipedia articles, and the far more extensive references in existing Wikipedia articles for each entry, header species, and other relevant taxon.

Metabolic and Physiological Adaptations with Opuntia
Adapting our food production chain and increasing the flora and fauna’s livelihood in climate change-affected areas using Opuntia is not only theoretical but already exists in practice in many places. This cactus grows in unsuitable soil for most species as it is adapted to arid and semi-arid soils and hot weather. In these regions, Opuntia protects from erosion and contributes to soil health. Opuntia has a high potential as an invasive species, with caution always being recommended when dealing with this specie. The high content of specific compounds, such as proline, indicaxanthin, and betanin, found in Opuntia ficus-indica, influence the plant’s adaptation to unfavourable conditions.

Blood–Brain Barrier Transport of Transferrin and Insulin
Biologics can be re-engineered for blood-brain barrier (BBB) transport as IgG fusion proteins, where the IgG domain is a monoclonal antibody (MAb) that targets an endogenous BBB transporter, such as the insulin receptor (IR) or transferrin receptor (TfR). The IR and TfR at the BBB transport the receptor-specific MAb in parallel with the transport of the endogenous ligand, insulin or transferrin.

Macchi C.202
The Macchi C.202 Folgore (Italian "thunderbolt") was an Italian fighter aircraft developed and manufactured by Macchi Aeronautica. It was operated mainly by the Regia Aeronautica (RA; Royal (Italian) Air Force) in and around the Second World War. According to aviation author David Mondey, the Folgore has been considered to be one of the best wartime fighters to serve in large numbers with the Regia Aeronautica. The C.202 was designed by a team headed by the company's chief of design, Italian aeronautics engineer Mario Castoldi. As per company tradition, Macchi aircraft designed by Mario Castoldi received the "C" letter in their model designation, hence the Folgore is commonly referred to as the C.202 or MC.202. The C.202 was a development of the earlier C.200 Saetta, powered by an Italian-built version of the German Daimler-Benz DB 601Aa engine and featuring a redesigned fuselage for greater streamlining. During July 1941, the Folgore went into service with the Regia Aeronautica. In combat, it very quickly proved itself to be an effective and deadly dogfighter against its contemporaries. During its service life, the C.202 was deployed on all fronts in which Italy was involved. During late 1941, it commenced offensive operations over Malta and in North Africa, where Italian and German forces were engaged in heavy combat against British and later United States operations. The C.202 continued to be used in North Africa as late as mid-1943, by which point the type was withdrawn to support defensive efforts in Sicily and the Italian mainland following their invasion by Allied forces. It also saw limited use on the Eastern Front. Following the 1943 Armistice with Italy, the type was mostly used as a trainer aircraft. The type was also operated by Croatia. The Australian ace Clive Caldwell, who fought a wide variety of German, Italian and Japanese fighters during 1941–45, later stated that the C.202 was "one of the best and most undervalued of fighters". The C.202 also had its defects: like its predecessor, the C.200, it could enter a dangerous spin. The radios were unreliable, routinely forcing pilots to communicate by waggling their wings and Western historians regard the C.202 as insufficiently armed, being furnished with just a pair of machine guns that had a tendency for jamming. Still in mid-Summer 1942, in North Africa, the Folgore achieved a ratio kill/loss better than that of the Messerschmitt Bf 109s.

T6SS-mediated Stress Responses Influence
The bacterial type VI secretion system (T6SS) is a protein secretion apparatus widely distributed in Gram-negative bacterial species. Many bacterial pathogens employ T6SS to compete with the host and to coordinate the invasion process. The T6SS apparatus consists of a membrane complex and an inner tail tube-like structure that is surrounded by a contractile sheath and capped with a spike complex. A series of antibacterial or antieukaryotic effectors is delivered by the puncturing device consisting of a Hcp tube decorated by the VgrG/PAAR complex into the target following the con-traction of the TssB/C sheath, which often leads to damage and death of the competitor and/or host cells. As a tool for protein secretion and interspecies interactions, T6SS can be triggered by many different mechanisms to respond to various physiological conditions.
