Tricuspid Atresia
Tricuspid atresia (TA) is a cyanotic, congenital heart defect (CHD) and is defined as congenital absence or agenesis of the morphologic tricuspid valve. It is the third most common cyanotic CHD, and is the most common cause of cyanosis with left ventricular hypertrophy. The prevalence of TA is estimated to be 2.9% of autopsy cases and 1.4% to 1.5% of the clinical cases of CHD.

The Spemann Organizer
In 1924, to understand the processes involved in developmental biology, Spemann and Mangold transplanted a blastopore lip between different ectodermal regions of amphibian embryos. The transplanted dorsal tissue differentiated mostly into a notochord, while the ectoderm of the host dorsal tissue that was sitting above the transplanted region (blastopore lip) was induced and differentiated to form a Siamese twin containing dorsal tissues such as somites and a neural plate, which would form the central nervous system, forming the bulk of a second axis. The major findings were that the transplant had altered the fate of the overlying cells and that the neural folds were built from recipient cells and not donor cells. Spemann and Mangold discovered the organizing center in the dorsal blastopore lip of amphibians. This center consists of a cluster of cells in the developing embryo that have the ability to interact and instruct morphogenesis in the surrounding cells during gastrulation. When transplanted to the ventral side of the embryo, the center will induce the formation of a secondary axis, promoting the development of the central nervous system, organs, and tissues, as well as the formation of the main body axis. Spemann and Mangold found the first evidence of the organizing center, thereafter called the “Spemann organizer”, and its major role in the development of vertebrates. This discovery also introduced the concept of induction in embryonic development, which refers to the method used by specific cells to affect the fate of other embryonic cells. A major milestone had been achieved for developmental biology.

Death Anxiety (Psychology)
Death anxiety is anxiety caused by thoughts of one's own death; it is also referred to as thanatophobia (fear of death). Death anxiety is different from necrophobia, the latter is the fear of others who are dead or dying, whereas the former concerns one's own death or dying. Popular psychotherapist Robert Langs proposed 3 different causes of death anxiety: Predatory, predator, and existential. In addition to his research, many theorists such as Sigmund Freud, Erik Erikson, Ernest Becker, and others have contemplated death and death anxiety and how it relates to human psychology. Death anxiety has been found to affect people of differing demographic groups as well; such as men versus women, young versus old, etc.    Additionally, there is anxiety caused by death-recent thought-content, which might be classified within a clinical setting by a psychiatrist as morbid and/or abnormal. This classification pre-necessitates a degree of anxiety which is persistent and interferes with everyday functioning. Lower ego integrity, more physical problems and more psychological problems are predictive of higher levels of death anxiety in elderly people perceiving themselves close to death. Death anxiety can cause extreme timidness with a person's attitude towards discussing anything to do with death. Findings from one systematic review demonstrated that death anxiety features across several mental health conditions. One meta-analysis of psychological interventions targeting death anxiety showed that death anxiety can be reduced using cognitive behavior therapy.

Mozilla Public License
The Mozilla Public License (MPL) is a free and open-source weak copyleft license for most Mozilla Foundation software such as Firefox and Thunderbird The MPL license is developed and maintained by Mozilla, which seeks to balance the concerns of both open-source and proprietary developers; it is distinguished from others as a middle ground between the permissive software BSD-style licenses and the General Public License. So under the terms of the MPL, it allows the integration of MPL-licensed code into proprietary codebases, but only on condition those components remain accessible. MPL has been used by others, such as Adobe to license their Flex product line, and The Document Foundation to license LibreOffice 4.0 (also on LGPL 3+). Version 1.1 was adapted by several projects to form derivative licenses like Sun Microsystems' Common Development and Distribution License. It has undergone two revisions: the minor update 1.1, and a major update version 2.0 nearing the goals of greater simplicity and better compatibility with other licenses.

Ordnance QF 6-pounder
The Ordnance Quick-Firing 6-pounder 7 cwt,[note 1] or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army (as the 57 mm Gun M1). It was also used as the main armament for a number of armoured fighting vehicles. Although designed before the start of the war, it did not reach service until the North African Campaign in April 1942. There, it replaced the 2-pounder as an anti-tank gun, allowing the 25-pounder gun-howitzer to revert to its intended artillery role.

Perceived Green Value (PGV)
Perceived Green Value (PGV) is defined as consumers’ overall evaluation and appraisal of products in regards to their perceived environmental and sustainable advantages. This concept derives from consumer perceived value (CPV) theory, which mainly considers two dimensions, which are the functional value (quality, services, price, and convenience values) and the symbolic value (aesthetic, emotional, social, and reputational values) .

Acute and Chronic Stress Reactions and HPA Axis
Due to the influence of various stressful stimuli, psychological stress alters the homeostasis of the organism. Consequently, the organism reacts, and the sympathetic-adrenal-medullary (SAM) system and the hypothalamic-pituitary-adrenal (HPA) axis are activated, producing and releasing specific hormones. In addition to acute stress, chronic psychological stress also activates the HPA axis, which causes elevated glucocorticoid levels.

Green Lean Six Sigma Approach
Green lean six sigma (GLSS) is an emerging approach towards environmental sustainability in conjunction with operational achievements. The success of this approach is premised on an understanding of the different components of a GLSS program; being the determinants for its outcomes. The aim of this paper is to investigate the various constructs of GLSS that play an essential role in achieving environmental sustainability. For this purpose, a systematic review of available literature has been conducted to evaluate the drivers, enablers (tools), and outcomes of a GLSS strategy as well as its critical success factors and barriers. Findings reveal that these constructs of GLSS as a holistic approach can facilitate an organization to better accomplish environmental objectives such as waste minimization, emission reduction, and resource conservation as compared to constructs of only one or any two of these strategies. Based on the analysis, an integrated GLSS framework is developed for environmental sustainability in addition to identifying vital research gaps and future directions.

Lactoferrin and Ferrous Sulfate Supplementation in Iron-Deficiency Anemia
Ferrous sulfate is a commonly used iron supplement for the correction of iron-deficiency anemia but with frequent gastrointestinal side effects. Milk-derived iron-binding glycoprotein lactoferrin possesses well gastrointestinal tolerance and fewer side effects caused by the intake of high-dose iron. However, the underlying mechanism of the iron-enhancing effect of lactoferrin remains unclear. In addition, the comparative efficacies between lactoferrin and ferrous sulfate are also remained to be determined. Studies support lactoferrin as a superior supplement to ferrous sulfate regarding the improvement in serum iron parameters and hemoglobin levels.

Architecture and Challenges of Industrial Internet of Things
The inherent complexities of Industrial Internet of Things (IIoT) architecture make its security and privacy issues becoming critically challenging. Numerous surveys have been published to review IoT security issues and challenges. The studies gave a general overview of IIoT security threats or a detailed analysis that explicitly focuses on specific technologies. However, recent studies fail to analyze the gap between security requirements of these technologies and their deployed countermeasure in the industry recently. Whether recent industry countermeasure is still adequate to address the security challenges of IIoT environment are questionable.

Minor Basilica
A minor basilica (Latin: Basilica minor, Basilicæ minores in plural) is a Catholic church building that has been granted the title of basilica by the Holy See or immemorial custom. Presently, the authorising decree is granted by the Pope through the Congregation for Divine Worship and the Discipline of the Sacraments. In relation to churches, writers on architecture use the term "basilica" to describe a church built in a particular style. The early Christian purpose-built cathedral basilica of the bishop was in this style, constructed on the model of the semi-public secular basilicas, and its growth in size and importance signalled the gradual transfer of civic power into episcopal hands, which was under way in the 5th century. In the 18th century, the term took on a canonical sense, unrelated to this architectural style. Basilicas in this canonical sense are divided into major ("greater") and minor basilicas. Today only four, all in Rome, are classified as major basilicas.

Origins of Judaism
The origins of Judaism lie in the Bronze Age amidst polytheistic ancient Semitic religions, specifically Canaanite religion, co-existing with a syncretization with elements of Babylonian religion and of the worship of Yahweh reflected in the early prophetic books of the Hebrew Bible. During the Iron Age I, the Israelite religion became distinct from other Canaanite religions due to the unique monolatristic (proto-monotheistic) worship of Yahweh. During the Babylonian captivity of the 6th and 5th centuries BCE (Iron Age II), certain circles within the exiled Judahites in Babylon refined pre-existing ideas about monotheism, election, divine law and Covenant into a strict monotheistic theology which came to dominate the former Kingdom of Judah in the following centuries. From the 5th century BCE until 70 CE, Israelite religion developed into the various theological schools of Second Temple Judaism, besides Hellenistic Judaism in the diaspora. Second Temple eschatology was significantly influenced by Zoroastrianism. The text of the Hebrew Bible was redacted into its extant form in this period and possibly also canonized as well. Rabbinic Judaism developed during Late Antiquity, during the 3rd to 6th centuries CE; the Masoretic Text of the Hebrew Bible and the Talmud were compiled in this period. The oldest manuscripts of the Masoretic tradition come from the 10th and 11th centuries CE; in the form of the Aleppo Codex of the later portions of the 10th century CE and the Leningrad Codex dated to 1008–1009 CE. Due largely to censoring and the burning of manuscripts in medieval Europe the oldest existing manuscripts of various rabbinical works are quite late. The oldest surviving complete manuscript copy of the Babylonian Talmud is dated to 1342 CE.
