Mass Effect

Mass Effect is a science fiction action role-playing third person shooter video game series developed by the Canadian company BioWare and released for the Xbox 360, PlayStation 3, and Microsoft Windows, with the third installment also released on the Wii U. The fourth game will release on Microsoft Windows, PlayStation 4 and Xbox One.

The original trilogy largely revolves around a soldier named Commander Shepard, whose mission is to save the galaxy from a race of powerful mechanical beings known as the Reapers and their agents, including the first game's antagonist Saren Arterius. The first game sees Shepard investigating Saren, whom Shepard slowly comes to understand is operating under the guidance of Sovereign, a Reaper left behind in the Milky Way tens of thousands of years before, when the Reapers exterminated virtually all sentient organic life in the galaxy as part of a recurrent cycle of genocide for an unknown purpose. Sovereign's purpose is to trigger the imminent return of the Reaper fleet hibernating in extra-galactic dark space, restarting the process of extermination. The second game takes place two years later, and sees Shepard battling the Collectors, an alien race abducting entire human colonies in a plan to help the Reapers return to the Milky Way. The final game of Shepard's trilogy centers on the war waging against the Reapers.

4K resolution

4K resolution, also called 4K, refers to a display device or content having horizontal resolution on the order of 4,000 pixels. Several 4K resolutions exist in the fields of digital television and digital cinematography. In the movie projection industry, Digital Cinema Initiatives (DCI) is the dominant 4K standard. In television and consumer media, 4K UHD or UHD-1 is the dominant 4K standard. By 2015, 4K television market share had increased greatly as prices fell dramatically during 2014 and 2015. By 2025, more than half of US households are anticipated to have a 4K-capable TV (2160p), which would be much faster than the adoption curve of FullHD (1080p).

Definitions

The name "4K resolution" refers to a horizontal resolution of approximately 4,000 pixels. The use of width to characterize the overall resolution marks a switch from previous television standards such as 480i and 1080p, which categorize media according to its vertical dimension. Using that same convention, 4K UHD would be named 2160p.

Call of Duty

Call of Duty is a first-person shooter video game franchise. The series began on Microsoft Windows, and later expanded to consoles and handhelds. Several spin-off games have been released. The earlier games in the series are set primarily in World War II, including Call of Duty, Call of Duty 2, and Call of Duty 3. Beginning with Call of Duty 4: Modern Warfare, which is set in modern times, the series has shifted focus away from World War II. Modern Warfare, released November 2007, was followed by World at War and Modern Warfare 2. Black Ops, released November 2010, takes place in the Cold War, while Modern Warfare 3, released November 2011, takes place in a near-future setting. Black Ops II, released November 2012, takes place mainly in the year 2025. Call of Duty: Ghosts was released in November 2013. In May 2014, Advanced Warfare was announced. On April 9, 2015, Treyarch announced Black Ops III.

The Call of Duty games are published and owned by Activision. While Infinity Ward is still a developer, Treyarch and Sledgehammer Games also develop several of the titles with the release of the studios' games alternating with each other. Some games have been developed by Gray Matter Interactive, Nokia, Exakt Entertainment, Spark Unlimited, Amaze Entertainment, n-Space, Aspyr, Rebellion Developments, Ideaworks Game Studio, and nStigate Games. The games use a variety of engines, including the id Tech 3, the Treyarch NGL, and the IW engine.

Ultra-high-definition television

Ultra-high-definition television (also known as 2160p, UHD-1, Super Hi-Vision, Ultra HD television, UltraHD, UHDTV, or UHD) includes 4K UHD (2160p) and 8K UHD (4320p), which are two digital video formats proposed by NHK Science & Technology Research Laboratories and defined and approved by the International Telecommunication Union (ITU).

The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840×2160 pixels.

Alternative terms

Ultra-high-definition television is also known as Ultra HD, UHD, and UHDTV. In Japan, 8K UHDTV will be known as Super Hi-Vision since Hi-Vision was the term used in Japan for HDTV. In the consumer electronics market companies had previously only used the term 4K at the 2012 CES but that had changed to Ultra HD during the 2013 CES. The Ultra HD term is an umbrella term that was selected by the Consumer Electronics Association after extensive consumer research.

Cassiopea andromeda

Cassiopea andromeda (Upside-down jellyfish) is a type of jellyfish that usually lives in intertidal sand or mud flats, shallow lagoons, and around mangroves. This jellyfish, many times mistaken for a sea anemone, usually has its mouth upward on the bottom. Its bell, which is yellow-brown with streaks and spots that are white or pale, vibrates to make the water flow through its arms for respiration and the obtaining of food.

Alimentation and strategies

Cassiopea andromeda is carnivorous and eats small animals from the sea or just pieces of them after it paralyzes its prey with its mucous and nematocysts when they are released. This jellyfish also lives in a symbiotic relationship with photosynthetic dinoflagellate algae, the Zooxanthellae, and with shrimps. The Zooxanthellae live in the tissues of the ventral surface of its body and it is the responsible for the color of it. As the Zooxanthellaeon gets food for the Cassiopea andromeda, in response, it gets the sunlight that is necessary for the photosynthetic dinoflagellate algae. Therefore, the shrimp has a different symbiotic relationship with this jellyfish. It lives in its tentacles and protects it by taking the parasites off. In exchange, the Cassiopea andromeda mainly offers protection to the shrimp from the environment. This symbiotic relationship is called mutualism, where both species benefit from their interactions.
