Thread Block
A thread block is a programming abstraction that represents a group of threads that can be executed serially or in parallel. For better process and data mapping, threads are grouped into thread blocks. The number of threads varies with available shared memory. 'The number of threads in a thread block is also limited by the architecture to a total of 512 threads per block.' The threads in the same thread block run on the same stream processor. Threads in the same block can communicate with each other via shared memory, barrier synchronization or other synchronization primitives such as atomic operations. Multiple blocks are combined to form a grid. All the blocks in the same grid contain the same number of threads. Since the number of threads in a block is limited to 512, grids can be used for computations that require a large number of thread blocks to operate in parallel. CUDA is a parallel computing platform and programming model that higher level languages can use to exploit parallelism. In CUDA, the kernel is executed with the aid of threads. The thread is an abstract entity that represents the execution of the kernel. A kernel is a small program or a function. Multi threaded applications use many such threads that are running at the same time, to organize parallel computation. Every thread has an index, which is used for calculating memory address locations and also for taking control decisions.

Associations between Population Density and Health Outcomes
Both density of population and proximity to man-made activities, as well as the natural environment, concentrate risk for humans. Population density is therefore a measure of “the degree of pressure on natural resources” as well as an indicator reflecting the level of human activity within a specific bounded landscape. Exposure to contaminants from soil, water or air coupled with social or economic vulnerability and population density may increase potential harm to health at a subclinical or clinical level.

Processing Properties of Starch
Starch is the second most abundantly available natural polymer in the world, after cellulose. If we add its biodegradability and non-toxicity to the natural environment, it becomes a raw material very attractive for the food and non-food industries. However, in the latter case, mainly due to the high hydrophilicity of starch, it is necessary to carry out many more or less complex operations and processes. One of the fastest growing industries in the last decade is the processing of biodegradable materials for packaging purposes. This is mainly due to awareness of producers and consumers about the dangers of unlimited production and the use of non-degradable petroleum polymers.

UAVs to CBRN Threats monitoring
Unmanned aerial vehicles (UAVs) play an increasingly important role in various areas of life, including in terms of protection and security. The possibilities of using the devices were analyzed in terms of weather conditions, construction, and used materials in CBRN (chemical, biological, radiological, nuclear) threat situations. It was found that, thanks to the use of appropriate sensors, cameras, and software of UAVs integrated with a given system, it is possible to obtain information on air quality at a given moment, which is very important for the safety of people and the environment. However, several elements, including the possibility of use in acidification conditions, requires refinement to changing crisis conditions.

Exploiting Proteotoxic Stress in Cancer
Cancer cells typically have elevated proteotoxic stress as a result of genomic instability. The disruption of protein homeostasis causes endoplasmic reticulum stress. If not promptly managed, it could lead to a global decline in cellular function and eventual cell death[1]. This summary of review explores different protein quality control pathways and the translation of drugs targeting proteotoxic stress in haematologic cancers (using multiple myeloma as an example) versus solid cancers (using Triple Negative Breast Cancer as an example).

Facioscapulohumeral Muscular Dystrophy
Facioscapulohumeral muscular dystrophy (FSHD)—the worldwide third most common inherited muscular dystrophy caused by the heterozygous contraction of a 3.3 kb tandem repeat (D4Z4) on a chromosome with a 4q35 haplotype—is a progressive genetic myopathy with variable onset of symptoms, distribution of muscle weakness, and clinical severity.  A rough correlation between the phenotypic severity of FSHD and the D4Z4 repeat size has been reported, and the majority of patients with infantile FSHD obtain a very short D4Z4 repeat length (one to three copies, EcoRI size 10–14 kb), in contrast to the classical, slowly progressive, form of FSHD (15–38 kb). With the increasing identifications of case reports and the advance in genetic diagnostics, recent studies have suggested that the variant of FSHD is not a genetically separate entity but a part of the FSHD spectrum. Nevertheless, many questions about the clinical phenotype and natural history of FSHD remain unanswered, limiting evidence-based clinical management.

Absenteeism
Absenteeism is a habitual pattern of absence from a duty or obligation without good reason. Generally, absenteeism is unplanned absences. Absenteeism has been viewed as an indicator of poor individual performance, as well as a breach of an implicit contract between employee and employer. It is seen as a management problem, and framed in economic or quasi-economic terms. More recent scholarship seeks to understand absenteeism as an indicator of psychological, medical, or social adjustment to work.

Emergency Communication Networks
Emergency communication refers to the communication means and methods needed for the extensive use of various communication resources to support rescues, including emergency rescues, and the necessary communication in the case of natural or manufactured emergencies. Because of the characteristics of disasters, making effective use of limited resources to provide the best communication services is a key problem. Unlike the traditional communication network, the emergency communication network is a complex network, and enables the implementation of emergency rescue activities and provides the primary conditions for the realization of emergency rescue functions. Its network structure has a significant impact on rescue efficiency. In different emergency situations, the demand for emergency communication is different, and the technical means used are different. Emergency communication mainly has the following characteristics: uncertainty of time and place; uncertainty of capacity demand; high degree of timeliness of the emergency communication; complexity of the environment; uncertainty of the degree of damage to the communication network itself; and diversification of information.

Avocado-Derived Biomass
The avocado (Persea americana Mill.) is a tree native to Mexico and Guatemala, and currently it is cultivated in more than 70 countries. Avocado consumption, fresh or in the form of processed products, is growing everywhere and it has caused a large number of countries to invest heavily in avocado production. The industrialization of avocado gives as a result a huge amount of waste: peel, stone, tree pruning, and oil extraction wastes. Although the industrial application of these biomasses is still limited, numerous studies suggest that they can serve as raw materials to obtain bioenergy and different types of bioproducts. To take full advantage of them, it would particularly interesting to develop biorefinery models.

Microcystins
Harmful cyanobacterial blooms pose an environmental health hazard due to the release of water-soluble cyanotoxins. One of the most prevalent cyanotoxins in nature is microcystins (MCs), a class of cyclic heptapeptide hepatotoxins, and they are produced by several common cyanobacteria in aquatic environments. Once released from cyanobacterial cells, MCs are subjected to physical chemical and biological transformations in natural environments. MCs can also be taken up and accumulated in aquatic organisms and their grazers/predators and induce toxic effects in several organisms, including humans.

Entomopathogenic Fungi
Numerous fungal microorganisms are pathogenic for many insect and nematode species and are able to control the natural populations of these by limiting their spread. There are more than one thousand species that infect and parasitize insects. Entomopathogenic Hypocreales are opportunistic pathogens highly adapted to infect insects and mites as a result of adaptations developed over time, such as the ability to overcome the host’s immune system defenses and the production of cuticular enzymes and degrading substances. They are globally and widely distributed in nature, ubiquitous across all environmental matrices, and can be easily grown in mass.

Middle East Respiratory Syndrome
Middle East respiratory syndrome (MERS), also known as camel flu, is a viral respiratory infection caused by Middle East respiratory syndrome–related coronavirus (MERS-CoV). Symptoms may range from none, to mild, to severe. Typical symptoms include fever, cough, diarrhea, and shortness of breath. The disease is typically more severe in those with other health problems. MERS-CoV is a coronavirus believed to be originally from bats. However, humans are typically infected from camels, either during direct contact or indirectly. Spread between humans typically requires close contact with an infected person. Its spread is uncommon outside of hospitals. Thus, its risk to the global population is currently deemed to be fairly low. Diagnosis is by rRT-PCR testing of blood and respiratory samples. (As of 2021) there is no specific vaccine or treatment for the disease, but a number are being developed. The World Health Organization (WHO) recommends that those who come in contact with camels wash their hands and not touch sick camels. They also recommend that camel-based food products be appropriately cooked. Treatments that help with the symptoms and support body functioning may be used. The first identified case occurred in June 2012 in Jeddah, Saudi Arabia, and most cases have occurred in the Arabian Peninsula. Over 2,500 cases have been reported as of January 2021, including 45 cases in the year 2020. About 35% of those who are diagnosed with the disease die from it. Larger outbreaks have occurred in South Korea in 2015 and in Saudi Arabia in 2018.

Apostolic Administrator
An apostolic administrator in the Catholic Church is a prelate appointed by the Pope to serve as the ordinary for an apostolic administration. An apostolic administration can either be an area that is not yet a diocese (a stable 'pre-diocesan', usually missionary apostolic administration) or for a diocese, eparchy or similar permanent ordinariate (such a territorial prelature or a territorial abbacy) that either has no bishop (an apostolic administrator sede vacante, as after an episcopal death or resignation) or, in very rare cases, has an incapacitated bishop (apostolic administrator sede plena).

Biosynthesis Investigations of Terpenoids Antimicrobial Agents
Terpenoids, also known as isoprenoids, are one of the largest natural product families, constituting more than 40,000 primary and secondary metabolites, including monoterpenes (53%), diterpenoids (1%), sesquiterpenes (28%), and others (18%). The basic unit of terpenes is the isoprene unit (C5H8), which is a simple hydrocarbon. It is the main precursor and could be post-modified through the cytosolic mevalonate (MVA) pathway or the plastid methyl erythritol phosphate (MEP) pathway. Terpenoids are a major source of bioactive natural products.

Need for Widely Applicable Cultural Competencies in the Healthcare of Humans and Animals
This entry discusses the importance of cultural competence in the healthcare of humans and animals, its challenges, its mixed research results, and the need for widely applicable competencies. Although there is research evidence showing that cultural competence is linked with patient satisfaction, better doctor–patient relationships, adherence to therapy, and to some extent, better health outcomes, there is a huge variety of models and competencies in the literature, which has sometimes resulted in inclusive outcomes, confusion as to what constitutes the necessary competencies, and patchy implementation. In spite of the development of cultural competence in human healthcare, its implementation in veterinary medicine remains poor. On this note, the aims of this entry are to provide a brief overview of the cultural competence in healthcare and veterinary medicine and education, to outline the important facts, and to highlight the need for more standardisation in implementing and testing widely applicable cultural competencies for both human and veterinary healthcare.

Rationalization
Rationalization, in the realm of social science, refers to the process by which individuals or organizations seek to justify and legitimize their actions, decisions, or beliefs through logical reasoning or systematic planning. This concept, prominently associated with Max Weber's sociological theories, suggests that rationalization leads to the increased application of calculative and efficient means in various aspects of human life, ultimately influencing the organization of social structures and institutions. It involves the substitution of traditional, emotional, or value-based considerations with rational, objective, and methodical approaches, shaping the modernization and bureaucratization of societies.
