 Phase - Wikipedia, the free encyclopedia
The phase (waves) of a waveform is the position of any peak or trough compared to the same feature on a second waveform.
A phase (matter) of matter is a physically distinctive form of a substance, such as the solid, liquid, and gaseous states of ordinary matter.
The term phase is used in small group communication, conflict, and negotiation to refer to segments during which the types of communication that occur remain approximately similar throughout, but clearly distinct from the types that occur during other phases.

 Milestone 19 Cyclin' into S phase   (Site not responding. Last check: 2007-10-22)
In all eukaryotic cells, entry into M phase is regulated by a complex of the cyclin-dependent kinase (CDK) cdc2 and cyclin B (also known as MPF; see milestone 7).
Entry into S phase is regulated in a similar way in both fission and budding yeast.
Elledge, S. and Spottswood, M. A new human p34 protein kinase, CDK2, identified by complementation of a cdc28 mutation in Saccharomyces cerevisiae, is a homolog of Xenopus Eg1.

 The Thermodynamic Modeling of Multicomponent Phase Equilibria
Phase diagrams are visual representations of the state of a material as a function of temperature, pressure, and concentrations of the constituent components and are, therefore, frequently hailed as basic blueprints or roadmaps for alloy design, development, processing, and understanding.
Thus, all phases are assumed to be in thermodynamic equilibrium at all temperatures during solidification.
Thermodynamic calculation of the phase equilibria of a multicomponent alloy was interfaced with a micromodel for computing the change of fraction solid and temperature, given a specified change in enthalpy during the liquid-solid transformation.

It is not uncommon to change one's phase by as much as 6 hours per day on a regular basis.
"change phase the easy way": To stay asleep, etc. However, some claim that either staying awake longer or sleeping longer is easy, and that it is *shortening* your day or night that is really hard (see {wrap around}).
The "jet lag" that afflicts travelers who cross many time-zone boundaries may be attributed to two distinct causes: the strain of travel per se, and the strain of changing phase.

 CANCER SUSCEPTIBILITY AND S PHASE INITIATION SITES
The applicants hypothesize that this vulnerability may be associated with carcinogen-induced alterations of regions of DNA that regulate the origins of replication that control the start of the S phase.
Origins that are activated as cells enter S phase might belong to a different class than those that activate later, resulting in orderly duplication of the genome.
Mutations in regulatory sequences that control the initiation of replication at the start of the S phase may represent a mechanism by which the regulation of cell proliferation is relaxed.

 Chromosome Movements During S phase
To date in both of the two cases in which careful analysis was carried out, we have observed a specific movement of the labeled chromosome region restricted to a specific time during S phase.
In the first case, a late-replicating, heterochromatic gene amplified chromosome arm was observed to move from the nuclear periphery to the nuclear interior during middle to late S phase.
In the second case, an insertion of ~10-20 copies of a transgene carrying the lac op repeat was shown to locate at the nuclear periphery in ~75% of cells during G1, but move to the nuclear interior during early S phase.

 Phase 10 Card game rules
Phases are made of sets, runs, cards all of one color, or a combination of sets and runs.
Once a "Wild" card has been played as a certain card in a Phase it cannot be replaced by the intended card and used elsewhere, but must remain as that card until the hand is over.
This qualifies as 1 run of 7 for Phase 4, but cannot be used as credit for either Phase 5 (1 run of 8) or Phase 6 (1 run of 9).

In Phase I clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
In Phase II clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.
In Phase III studies, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.

 The Cell Cycle
When a cell is in any phase of the cell cycle other than mitosis, it is often said to be in interphase.
The passage of a cell through the cell cycle is controlled by proteins in the cytoplasm.
This is only one mechanism by which the cell ensures that every portion of its genome is copied once — and only once — during S phase.
