  1. Mixing patterns

    Mixing patterns refer to systematic tendencies of one type of nodes in a network to connect to another type. For instance, nodes might tend to link to others that are very similar or very different. This feature is common in many social network s, although it also appears sometimes in non social networks. Mixing patterns are closely related to assortativity however, for the purposes of this article, the term is used to refer to assortative or disassortative mixing based on real world factors, either topological or sociological. Types of Mixing Patterns Mixing patterns are a characteristic of an entire network, referring to the extent for nodes to connect to other similar or different nodes. Mixing, therefore, can be classified broadly as assortative or disassortative. Assortative mixing is the tendency for nodes to connect to like nodes, while disassortative mixing captures the opposite case in which very different nodes are connected. Obviously, the particular node characteristics involved in the process of creating a link between a pair will shape a network s mixing patterns. For instance, in a sexual relationship network, one is likely to find a preponderance of male female links ..., Mixing patterns in networks. Phys. Rev.

  1. Bacterial patterns

    Orphan date April 2011 The pattern formation formation of patterns in the Bacterial growth growth of bacterial colony bacterial colonies has extensively been studied experimentally. Resulting morphologies appear to depend on the growth conditions. They include well known morphologies such as dense branched morphology DBM or diffusion limited aggregation DLA , but much complex patterns and temporal behaviour can be found. A large number of studies on pattern formation in bacterial colonies have been performed in Bacillus subtilis and in Proteus mirabilis . Mathematical modeling of colony growth can reproduce the observed morphologies and the effect of environmental changes. Employed models include Reaction diffusion system Cellular automata Colonies of Bacillus subtilis Colonies of Bacillus subtilis on a Petri dish can grow under controlled conditions. By varying agar concentration which permits the control of the hardness of the medium , and the nutrient concentration, the response of the colony to external stresses can be studied. The different morphologies appear in the following growth conditions High nutrients level, hard medium Eden like growth http www.phys.chuo u.ac.jp labs matusita images BacteriaFig B eden.htm High nutrients level, semi soft hardness of medium Periodical growth forming concentric rings http www.phys.chuo u.ac.jp labs matusita images BacteriaFig B concentric.htm High nutrients level, soft medium homogeneous, disk like growth http www.phys.chuo u.ac.jp labs matusita images BacteriaFig B fisher.htm Low nutrients level, hard medium DLA growth http www.phys.chuo u.ac.jp labs matusita images BacteriaFig B dla.htm Low nutrients level, soft medium DBM growth http www.phys.chuo u.ac.jp labs matusita images BacteriaFig B dbm.htm A complete morphological diagram can then be drawn by varying growth conditions. http www.phys.chuo u.ac.jp labs matusita images ... images of patterns in bacterial growth can be found in http www.genomenewsnetwork.org articles 05 ...   more details



  1. Patterns of Conflict

    Patterns of Conflict was a presentation by John Boyd military strategist Colonel John Boyd outlining his theories on modern combat and how the key to success was to upset the enemy s observation orientation decision action time cycle or loop , or OODA loop . Based on the OODA loop, the aim of the modern commander was to commit a series of very rapid but limited actions from different places with no apparent pattern to them. In effect, Patterns supported the idea of a counter blitz , a blitzkrieg in reverse, with numerous attacks followed by withdrawals to the rear. The aim was to confuse the enemy, reveal the enemy s intensions through the strength of the response, and present a misleading picture of the defender s own actions in order to disrupt the attacker s plan of action. First presented in 1976, Patterns grew enormously popular through the 1970s, and was re presented on many occasions, including a personal presentation to Richard Cheney 1981. A 1980 presentation to the US Marine Corps led to an entirely new doctrinal system being developed. His ideas also became the basis for the AirLand Battle , the US Army s European warfighting doctrine from 1982 into the late 1990s.

  1. Sound Patterns

    Sound Patterns 1961 is a musical piece or Musical composition composition for a cappella mixed choir chorus by Pauline Oliveros . Oliveros won the Gaudeamus International Composers Award in 1962 with this work. ref Von Gunden 1983, p.26 27 ref Rather than a traditional text, the work is constructed of Phone phonetics phonetic sounds chosen on the basis of their timbre . The piece is entirely notated, lasts about four minutes, and features an Exposition music exposition measures 1 12 , Musical development development 12 46 , and Recapitulation music recapitulation 47 59 . The sounds may be understood to reflect Oliveros interest in electronic music , which she recently had begun to work with. Heidi Van Gunden 1983 illustrates this point by highlighting four types of sounds that correspond to basic electronic music techniques white noise ring modulation ring modulated sounds percussion percussive Envelope disambiguation envelopes Audio filter filtered techniques White noise is created vocally through the initial consonant sh and variations such as s, z, wh, p, t, h, ct, d, ch, th, k, and sw. Ring modulation is imitated through rapidly changing the vowel content, percussive envelopes through lip pops, tongue clicks, snap fingers, and flutter lips , and filtering through Mute music muting such as by covering the mouth with one s hand, sounding the consonant M through tightly closed lips, or singing through clenched teeth. ibid, p.26 28 It is Oliveros most carefully composed piece and features only one measure of controlled improvisation linking the development to the recapitulation. The piece also predates similar compositions by Gy rgy Ligeti and Karlheinz Stockhausen Moment 1961 1962, revised 1965 . Ligeti was actually one of the judges for the Gaudeamus competition and featured unusual vocal sounds in his Aventures 1962 and Nouvelles Aventures 1962 65 .

  1. Flag and pennant patterns

    The flag and pennant patterns are commonly found patterns in the price charts of financially traded assets stocks, bonds, futures, etc . The patterns are characterized by a clear direction of the price trend, followed by a consolidation and rangebound movement, which is then followed by a resumption of the trend. br br Flag pattern The flag pattern is encompassed by two parallel lines. These lines can be either flat or pointed in the opposite direction of the primary market trend . The pole is then formed by a line which represents the primary trend in the market. The pattern is seen as the market potentially just taking a breather after a big move before continuing its primary trend. The chart below illustrates. br br Image bull flag.jpg center br Pennant pattern The pennant pattern is identical to the flag pattern in its setup and implications the only difference is that the consolidation phase of a pennant pattern is characterized by converging trendlines rather than parallel trendlines.
