Trees (comics)

Trees is a science fiction comic book series by Warren Ellis and Jason Howard, published by American company Image Comics. The first issue was published May 28, 2014. The narrative begins ten years after the arrival of massive and silent alien presences who stand on the surface of the earth like the "Trees" of the title, not moving and seeming to take no account of human life and society.

Plot

The narrative is divided into several points of view, all centered on the landing site of one of the Trees. Such locations include Rio de Janeiro, Mogadishu, New York City, "The City of Shu", (likely named after the ancient State of Shu located in what is now Sichuan, China), and Spitsbergen.

Reception

While ongoing, the series has so far been positively reviewed.

Vessel (Twenty One Pilots album)

Vessel is the third studio album from American duo Twenty One Pilots which was released on January 8, 2013. It is the band's first album on Fueled by Ramen.

Background

High-school colleagues Tyler Joseph, Nick Thomas, and Chris Salih formed Twenty One Pilots in 2009. The group released their debut album Twenty One Pilots. Both Thomas and Salih parted ways with the band in 2011. Soon afterwards Josh Dun joined the band; Joseph had been friends with Dun for around a year. Joseph first saw Dun when he was playing a show with House of Heroes. Joseph said that he "loved" the performance. The band released Regional at Best later that year. In June, the duo played their first out-of-state show to a group of 12 people. The pair soon gained popularity through a series of videos made by friend Mark Eshelman. The band played their last show as an unsigned band at the Newport Music Hall in Columbus, Ohio to a crowd of 1,800 in attendance. The band signed with Fueled by Ramen in 2012.

2–3–4 tree

In computer science, a 2–3–4 tree (also called a 2–4 tree) is a self-balancing data structure that is commonly used to implement dictionaries. The numbers mean a tree where every node with children (internal node) has either two, three, or four child nodes:

2-node

2-node

3-node

3-node

4-node

4-node

2–3–4 trees are B-trees of order 4; like B-trees in general, they can search, insert and delete in O(log n) time. One property of a 2–3–4 tree is that all external nodes are at the same depth.

2–3–4 trees are an isometry of red–black trees, meaning that they are equivalent data structures. In other words, for every 2–3–4 tree, there exists at least one red–black tree with data elements in the same order. Moreover, insertion and deletion operations on 2–3–4 trees that cause node expansions, splits and merges are equivalent to the color-flipping and rotations in red–black trees. Introductions to red–black trees usually introduce 2–3–4 trees first, because they are conceptually simpler. 2–3–4 trees, however, can be difficult to implement in most programming languages because of the large number of special cases involved in operations on the tree. Red–black trees are simpler to implement, so tend to be used instead.

Canada

Saskatchewan Highway 981, a provincial highway in the east central region of the Canadian province of Saskatchewan

United States

Louisiana Highway 981 (LA 981), a state highway in Louisiana that serves Pointe Coupee Parish

Pennsylvania Route 981 (PA 981), a state highway which runs across Westmoreland County

309 Road

The 309 road is a 22-kilometre (14 mi) long gravel road between the towns of Coromandel and Whitianga in New Zealand.

The 309 winds its way from Coromandel, on the west side of the Coromandel Peninsula, over the ranges to Whitianga, on the eastern side.

The road is considered extremely dangerous and deaths among tourists unfamiliar with the road and in unfit vehicles are common.

Places of interest along the road include Waiau Falls and the Kauri Grove, a stand of mature kauri trees.

2+2 road

A 2+2 road is a specific type of dual-carriageway being built in Ireland and in Sweden and in Finland, consisting of two lanes in each direction separated by a steel cable barrier.

These roads do not have hard shoulders and therefore they cannot be designated as Motorway at some future date. The Irish variant,however, has 3.5m lanes where there are a number of Swedish variants some with 3.25m wide lanes.

Junctions are generally at-grade roundabouts and minor roads cross under or over the mainline without connecting. They are also known as "Type 2 dual-carriageways" by the Irish National Roads Authority. These roads look similar to expressways, except that expressways often have interchanges, large medians or concrete barriers between traffic. The United States has 80,000 km of roads that fit this description.

First 2+2

The first road of this type opened in December 2007 as a new greenfield section of the N4 national primary route which joins Dublin to Sligo.
