In particle physics, the tracking is the act of measuring the direction and magnitude of charged particlesmomenta. The particles entering a tracker (the device used for tracking), release part of their energy in the device: the tracker has to be finely segmented in order to be able to reconstruct with good precision where the particle passed. Since the tracking is usually made in a region where a magnetic field is present, it is possible to reconstruct part of the helix made by the particle inside the tracker (that is called track), and from the track parameters, and by knowing the mass of the particle under study (which is known by the use of particle identification), it is possible to reconstruct the actual direction and magnitude of the particle momenta. From these information the tracking of charged particles can be used to reconstruct secondary decays, this can be done for B-tagging (in experiments like CDF or at LHC) or to fully reconstruct events (like in BaBar and Belle).
Tracking is a technique in which dogs are trained to locate certain objects by using the object's scent, for a variety of purposes.
Tracking has always been an essential skill for dogs to survive in the wild, through hunting and tracking down potential prey.
Physiological Mechanisms of Tracking
Primarily, dogs use their sense of smell, to find and follow a track. Dogs have a highly sensitive olfactory system superior to humans, and are able to discriminate between different human’s scents. Moreover, dogs are also able to use visual cues to follow a track.
Phases of tracking
There are three phases, which complete the process of tracking:
1. Searching Phase
2. Deciding Phase
3. Tracking phase
Factors influencing a dog’s tracking ability
There are several factors which influences a dog’s ability to track:
Physiological features of the dog are a factor. Some instances include with age, sex are influences. As a dog ages, their olfactory acuity decreases and decreases their ability to track. Furthermore, male dogs have found to be better at tracking than females, possibly due to sex differences in olfaction. Sniffing behaviour also influences olfaction, and therefore a dog’s ability to track. For example, a dog’s ability to sniff is higher when it is not panting due to fatigue – it is physically impossible for a dog to both pant and sniff at the same time and the mouth must be open or closed respectively
. However, dogs trained to track during physically demanding activities may have adapted their behaviour by increasing sniffing frequency to maximize olfaction, and tracking. Also, different dog breeds have varying suitability to different tasks of tracking. For example, the Bureau of Alcohol, Tobacco, Firearms and Explosives use Labrador Retrievers for their tracking purposes.

Maritime is an American indie pop band formed in 2003 after the breakup of The Promise Ring and The Dismemberment Plan. Eric Axelson (bass guitarist) of The Dismemberment Plan and Davey von Bohlen (singer/guitarist) and Dan Didier (drummer) of The Promise Ring started a band called In English. The group quickly signed a deal with the record label ANTI- and hired J. Robbins to produce their record. Robbins had previously produced records for both The Promise Ring and The Dismemberment Plan. After delivering the record to ANTI-, the company decided it did not want the record. The band changed its name to Maritime and signed with DeSoto Records. The band went on tour and self-released an EP called Adios on their own label, Foreign Leisure. On April 1, 2004, the band released its first full-length album, Glass Floor on DeSoto Records.
On February 6, 2006, Axelson announced that he was leaving the band. He was replaced on bass guitar by Justin Klug.
Their second album, We, the Vehicles, was released on April 18, 2006, on Flameshovel Records to wide critical acclaim.
