Cuteness and Its Emotional Responses
Cuteness is commonly associated with visual features such as large eyes, a disproportionately large head, round body shapes, and small size. While these traits are most often observed in infants and young animals, they also appear in inanimate objects and digital representations intentionally designed to evoke emotional appeal. Drawing on developmental psychology, behavioral science, neuroscience, and cultural studies, this paper examines five core emotional responses to cute stimuli: caretaking, socializing, whimsical, cute aggression, and kama muta (the feeling of being emotionally moved). These responses emerge from an interplay between evolutionary mechanisms, such as caregiving instincts, and cultural frameworks that shape how cuteness is perceived, expressed, and valued. The analysis highlights not only biological foundations but also cultural moderators, with particular attention to gender differences and the pervasive role of kawaii aesthetics in Japan’s popular culture, communication, and everyday life. This paper provides an overview of these emotional responses, situates them within their theoretical foundations and broader psychological and social implications, and proposes a framework for future research.

Green Star
In astronomy, a green star is a white or blueish star that appears greenish in some viewing conditions (see § Psychology below). Under typical viewing conditions, there are no greenish stars, because the color of a star is more or less given by a black-body spectrum. However, there are a few stars that appear greenish to some observers, due to the viewing conditions, for example the optical 'illusion' that a red object can make nearby objects look greenish (and vice versa). Some multiple star systems, such as Antares, have a bright reddish star where this contrast makes other stars in the system seem greenish.

Cost–Benefit Analysis for Road Infrastructure Projects
Cost–benefit analysis (CBA) is considered an effective evaluation method for fostering optimal decision-making and ranking of road infrastructures over decades. Eight distinct modelling categories used for CBA implementation were determined, each encompassing three different modelling approaches for capturing the data risk assessment (deterministic or probabilistic), CBA’s parameters interactive behavior (static or dynamic) and the considered economies (microeconomic or macroeconomic). In-depth content analysis led to the interpretation of the current status of extant models and the identification of three main knowledge gaps: the absence of the CBA’s inputs updating into a probabilistic environment, the deficiency of a dynamic interdependent framework and the necessity of homogenous cost datasets for road projects. Future research directions and a conceptual framework for modelling CBA into a microeconomic, probabilistic and dynamic environment are proposed providing decision-makers with new avenues for more reliable CBA modelling.

Yao's Millionaires' Problem
Yao's Millionaires' problem is a secure multi-party computation problem which was introduced in 1982 by computer scientist and computational theorist Andrew Yao. The problem discusses two millionaires, Alice and Bob, who are interested in knowing which of them is richer without revealing their actual wealth. This problem is analogous to a more general problem where there are two numbers [math]\displaystyle{ a }[/math] and [math]\displaystyle{ b }[/math] and the goal is to determine whether the inequality [math]\displaystyle{ a \geq b }[/math] is true or false without revealing the actual values of [math]\displaystyle{ a }[/math] and [math]\displaystyle{ b }[/math]. The Millionaires' Problem is an important problem in cryptography, the solution of which is used in e-commerce and data mining. Commercial applications sometimes have to compare numbers which are confidential and whose security is important. Many solutions have been introduced for the problem, among which the first solution, presented by Yao himself, was exponential in time and space.

Mathematical Modeling and Computational Tools in Drug Design
The conventional drug discovery approach is an expensive and time-consuming process, but its limitations have been overcome with the help of mathematical modeling and computational drug design approaches. Previously, finding a small molecular candidate as a drug against a disease was very costly and required a long time to screen a compound against a specific target. The development of novel targets and small molecular candidates against different diseases including emerging and reemerging diseases remains a major concern and necessitates the development of novel therapeutic targets as well as drug candidates as early as possible. In this regard, computational and mathematical modeling approaches for drug development are advantageous due to their fastest predictive ability and cost-effectiveness features. Computer-aided drug design (CADD) techniques utilize different computer programs as well as mathematics formulas to comprehend the interaction of a target and drugs. Traditional methods to determine small-molecule candidates as a drug have several limitations, but CADD utilizes novel methods that require little time and accurately predict a compound against a specific disease with minimal cost.

Electron Transport Layer
The electron transport layer (ETL) acts as a function of collecting electrons and blocking the transport of holes to the FTO electrode in the PSC. The mesoporous structure of the ETL promotes the crystallization and film formation of perovskite and shortens the migration path of photogenerated electrons. A suitable ETL should have an energy band position that matches the perovskite material.

Tirukkuṛaḷ
The Tirukkural (திருக்குறள், literally Sacred Verses), or shortly the Kural, is a classic Tamil language text consisting of 1,330 short couplets of seven words each, or Kurals. The text is divided into three books, each with aphoristic teachings on virtue (aram, dharma), wealth (porul, artha) and love (inbam, kama). Considered one of the greatest works on ethics and morality, it is known for its universality and secular nature. Its authorship is traditionally attributed to Valluvar, also known in full as Thiruvalluvar. The text has been dated variously from 300 BCE to 5th century CE. The traditional accounts describe it as the last work of the third Sangam, but linguistic analysis suggests a later date of 450 to 500 CE and that it was composed after the Sangam period. The Kural is traditionally praised with epithets and alternate titles such as "the Tamil Veda" and "the divine book." It emphasizes non-violence and moral vegetarianism as virtues for an individual.[a] In addition, it highlights truthfulness, self-restraint, gratitude, hospitality, kindness, goodness of wife, duty, giving, and so forth, besides covering a wide range of social and political topics such as king, ministers, taxes, justice, forts, war, greatness of army and soldier's honor, death sentence for the wicked, agriculture, education, abstinence from alcohol and intoxicants. It also includes chapters on friendship, love, sexual union, and domestic life. The Kural has been widely admired by scholars and influential leaders across the ethical, social, political, economical, religious, philosophical, and spiritual spheres over its history. These include Ilango Adigal, Kambar, Leo Tolstoy, Mahatma Gandhi, Albert Schweitzer, Constantius Joseph Beschi, Karl Graul, George Uglow Pope, Alexander Piatigorsky, and Yu Hsi. The text has been translated into at least 40 Indian and non-Indian languages. The Kural is considered a masterpiece and one of the most important texts of the Tamil Literature. The Tamil people and the government of Tamil Nadu have long celebrated and upheld the text with reverence.

Early Flood Warning System
The early-warning model for flash floods is based on a hydrological and geomorphological concept connected to the river basin, with the principle that flash floods will only occur where there is a high potential risk and when rainfall exceeds the threshold. In the model used to build flash-floods risk maps, the parameters of the basin are analyzed and evaluated and the weight is determined using Thomas Saaty’s analytic hierarchy process (AHP). The flash-floods early-warning software is built using open source programming tools. With the spatial module and online processing, a predicted precipitation of one to six days in advance for iMETOS (AgriMedia—Vietnam) automatic meteorological stations is interpolated and then processed with the potential risk maps (iMETOS is a weather-environment monitoring system comprising a wide range of equipment and an online platform and can be used in various fields such as agriculture, tourism and services). The results determine the locations of flash floods at several risk levels corresponding to the predicted rainfall values at the meteorological stations. The system was constructed and applied to flash floods disaster early warning for Thuan Chau in Son La province when the rainfall exceeded the 150 mm/d threshold. The system initially supported positive decision-making to prevent and minimize damage caused by flash floods.

Technology and Society
Technology society and life or technology and culture refers to the inter-dependency, co-dependence, co-influence, and co-production of technology and society upon one another. Evidence for this synergy has been found since humanity first started using simple tools. The inter-relationship has continued as modern technologies such as the printing press and computers have helped shape society. The first scientific approach to this relationship occurred with the development of tektology, the "science of organization", in early twentieth century Imperial Russia. In modern academia, the interdisciplinary study of the mutual impacts of science, technology, and society, is called science and technology studies. The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times have lessened physical barriers to communication and allowed humans to interact freely on a global scale, such as the printing press, telephone, and Internet. Technology has developed advanced economies, such as the modern global economy, and has led to the rise of a leisure class. Many technological processes produce by-products known as pollution, and deplete natural resources to the detriment of Earth's environment. Innovations influence the values of society and raise new questions in the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics. Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and alienates people. However, proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition.

2010–14 Portuguese Financial Crisis
2010–14 Portuguese financial crisis was part of the more wider downturn of the Portuguese economy that started in 2001 and possibly ended in 2016–17. The period from 2010 to 2014 was probably the hardest and more challenging part of the entire economic crisis; this period includes the 2011–14 international bailout to Portugal and was marked by an intense austerity policy, intenser than in any other period of the wider 2001–17 crisis. Economic growth stalled in Portugal in 2001–02; following years of internal economic crisis, the (international) Great Recession started to hit Portugal in 2008 and eventually led to the country being unable to repay or refinance its government debt without the assistance of third parties. To prevent an insolvency situation in the debt crisis, Portugal applied in April 2011 for bail-out programs and drew a cumulated €78.0 billion from the International Monetary Fund (IMF), the European Financial Stabilisation Mechanism (EFSM), and the European Financial Stability Facility (EFSF). Portugal leaved bailout in May 2014, the same year that positive economic growth re-appeared following three years of recession. The government achieved a 2.1% budget deficit in 2016 (the lowest since the restoration of democracy in 1974) and in 2017 the economy grew 2.7% (the highest growth rate since 2000). Greece and Ireland also went into a debt crisis in 2010. Together these debt crisis of these three countries marked the start of the European sovereign debt crisis.

76 Mm Gun M1
The 76 mm gun M1 was an American World War II–era tank gun developed by the U.S Ordnance Department in 1942 to supplement the 75 mm gun on the basic Medium tank M4. It was also used to arm the 76 mm Gun Motor Carriage M18 tank destroyer. Although the gun was tested in early August 1942 and classified on August 17, 1942, it was not until August 1943 that the Ordnance Department developed a mounting for the M4 tank that the tank forces would accept. It was not accepted for combat until July 1944. In January 1943, the decision was made to mount the 76 mm on the vehicle that would become the M18. By May 1944, it was being combat tested as the T70.
