Pointing-Out Instruction
The pointing-out instruction (ngo sprod) is the direct introduction to the nature of mind in the Tibetan Buddhist lineages of Mahāmudrā and Dzogchen. In these traditions, a "root guru" gives the "pointing-out instruction" in such a way that the disciple successfully recognizes the nature of mind. The tradition of conferring such instructions outside the context of formal empowerment (Sanskrit: abhiṣeka) is unique to the Kagyu and Nyingma lineages. Whether or not such instructions are valid without the formal empowerment has historically been a point of contention with the more conservative Gelug and Sakya lineages. The pointing-out instruction is often equated with the fourth formal vajrayana empowerment.

Houdini
Houdini is a 3D animation software application developed by Toronto-based SideFX, who adapted it from the PRISMS suite of procedural generation software tools. The procedural tools are used to produce different effects such as complex reflections, animations and particles system. Some of its procedural features have been in existence since 1987. Houdini is most commonly used for the creation of visual effects in film and television. It is used by major VFX companies such as Walt Disney Animation Studios, Pixar, DreamWorks Animation, Double Negative, ILM, MPC, Framestore, Sony Pictures Imageworks, Scanline VFX, Method Studios and The Mill. It has been used in many feature animation productions, including Disney's feature films Fantasia 2000, Frozen, Zootopia and Raya and the Last Dragon; the Blue Sky Studios film Rio, and DNA Productions' Ant Bully. SideFX also publishes Houdini Apprentice, a limited version of the software that is free of charge for non-commercial use.

Mini Clubman
The Mini Clubman is a supermini engineered and manufactured by BMW and sold under the Mini marque. The first-generation Clubman was introduced in 2007, as a variant of the Mini Hatch (Hardtop in the US). A commercial version called Clubvan was added to the range in 2012. The current second-generation model is produced since 2015 and available with front- and all-wheel drive.

Jpsi Meson
The J/ψ (J/psi) meson /ˈdʒeɪ ˈsaɪ ˈmiːzɒn/ or psion is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark. Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as "charmonium". The J/ψ is the most common form of charmonium, due to its spin of 1 and its low rest mass. The J/ψ has a rest mass of 3.0969 GeV/c2, just above that of the ηc (2.9836 GeV/c2), and a mean lifetime of 7.2×10−21 s. This lifetime was about a thousand times longer than expected. Its discovery was made independently by two research groups, one at the Stanford Linear Accelerator Center, headed by Burton Richter, and one at the Brookhaven National Laboratory, headed by Samuel Ting of MIT. They discovered they had actually found the same particle, and both announced their discoveries on 11 November 1974. The importance of this discovery is highlighted by the fact that the subsequent, rapid changes in high-energy physics at the time have become collectively known as the "November Revolution". Richter and Ting were awarded the 1976 Nobel Prize in Physics.

5-Oxo-Eicosatetraenoic Acid
5-Oxo-eicosatetraenoic acid (i.e. 5-oxo-6E,8Z,11Z,14Z-eicosatetraenoic acid; also termed 5-oxo-ETE and 5-oxoETE) is a Nonclassic eicosanoid metabolite of arachidonic acid and the most potent naturally occurring member of the 5-HETE family of cell signaling agents. Like other cell signaling agents, 5-oxo-ETE is made by a cell and then feeds back to stimulate its parent cell (see Autocrine signaling) and/or exits this cell to stimulate nearby cells (see paracrine signaling). 5-Oxo-ETE can stimulate various cell types particularly human leukocytes but possesses its highest potency and power in stimulating the human eosinophil type of leukocyte. It is therefore suggested to be formed during and to be an important contributor to the formation and progression of eosinophil-based allergic reactions; it is also suggested that 5-oxo-ETE may also contribute inflammation, cancer cell growth, and other pathophysiological responses.

Legendary Salamander in Popular Culture
References to the legendary salamander in popular culture—in fiction (especially fantasy fiction), games, animation, and so on—can be categorized in three ways: as a fantastic (sometimes magical) beast with an affinity with fire, as a true fire elemental, and allusions to the salamander's fiery nature.

2014 Taiwan Food Scandal
The 2014 Taiwan food scandal refers to a series of food safety incidents in Taiwan that came to light in 2014. Adulteration of cooking oil with recycled waste oil and animal feed oil was discovered in September 2014. Despite coming to light only in 2014, mass food adulteration by Taiwanese food conglomerates, however, has been suppressed for decades, and the food safety crisis has been among the reasons for the electoral defeat of the Kuomintang in late 2014. At least 1,256 businesses were affected in the gutter oil scandal. In November 2014, it was found that dried tofu products (a.k.a. dougan 豆乾) have been adulterated with an industrial dye, methyl yellow (a.k.a. dimethyl), for some 20 years. In December 2014, it was furthermore found that even regular non-dyed tofu has been found contaminated with carcinogens, resulting in over 25,000 kg recalled.

EcoHealth
EcoHealth (also referred to as Health Ecology) is an emerging field of study researching how changes in the earth’s ecosystems affect human health. It has many prospects. EcoHealth examines changes in the biological, physical, social and economic environments and relates these changes to human health. Examples of these changes and their effects abound. Common examples include increases in asthma rates due to air pollution, PCB contamination of game fish in the Great Lakes of the United States , and habitat fragmentation leading to increasing rates of Lyme disease. Recently virulent new infectious diseases such as SARS, Ebola virus, Nipah virus, bird flu and hantavirus have all been found to result from ecosystem change created by humans. These diseases have high death rates and very few effective therapies. EcoHealth is bringing together physicians, veterinarians, ecologists, life scientists, social scientists, agricultural scientists, landscape and urban planners, and others to study how ecosystem changes affect human health. EcoHealth strives to provide innovative, practical solutions to reduce or reverse the negative health effects of ecosystem change, and to use the salutogenic effects of functional ecosystems to improve public health.
