Image Carabelli.jpg thumb Diagram indicating cusp of Carabelli The cusp of Carabelli , or Carabelli s tubercle , or tuberculum anomale of Georg Carabelli is a small additional cusp dentistry cusp at the Commonly used terms of relationship and comparison in dentistry mesiopalatal line angle of maxillary first molar s. This extra cusp is usually found on the first molar, and becomes progressively less likely in the second, third molars. This cusp is entirely absent in some individuals and present in others in a variety of forms. In some cases, Carabelli s cusp may rival the main cusps in size. Other related forms include ridges, pits, or furrows. This additional cusp was first described in 1842 by the Hungarian Georg Carabelli Carabelli Gy rgy , the court dentist of the Austrian Empire Austrian Emperor Franz. The cusp of Carabelli is a heritable feature. Kraus 1951 proposed that Zygosity homozygosity of a gene is responsible for a pronounced tubercle, whereas the Zygosity heterozygote shows slight grooves, pits, tubercles or bulge. Later studies showed that the development of this trait is affected by multiple genes. Carabelli s cusp is most common among Europeans 75 85 of individuals and rarest in Pacific Islands 35 45 . This cusp may also be found in dogs and cats. Further reading Simon Hillson. 1996. Dental Anthropology . Cambridge University Press.

Context date October 2008 Unreferenced date October 2008 In mathematics , a cusp neighborhood is defined as a set of points near a cusp singularity cusp . Cusp neighborhood for a Riemann surface The cusp neighborhood for a hyperbolic Riemann surface can be defined in terms of its Fuchsian model . Suppose that the Fuchsian group G contains a parabolic element g. For example, the element t SL 2, Z where math t z begin pmatrix 1 & 1 0 & 1 end pmatrix z frac 1 cdot z 1 0 cdot z 1 z 1 math is a parabolic element. Note that all parabolic elements of SL 2, C are conjugacy class conjugate to this element. That is, if g SL 2, Z is parabolic, then math g h 1 th math for some h SL 2, Z . The set math U z in mathbf H Im z 1 math where H is the upper half plane has math gamma U cap U emptyset math for any math gamma in G langle g rangle math where math langle g rangle math is understood to mean the group mathematics group generated by g . That is, acts properly discontinuously on U . Because of this, it can be seen that the projection of U onto H G is thus math E U langle g rangle math . Here, E is called the neighborhood of the cusp corresponding to g . Note that the hyperbolic area of E is exactly 1, when computed using the canonical Poincar metric . This is most easily seen by example consider the intersection of U defined above with the fundamental domain math left z in H left z right 1, , left , mbox Re z , right frac 1 2 right math of the modular group , as would be appropriate for the choice of T as the parabolic element.

In number theory , a branch of mathematics , a cusp form is a particular kind of modular form , distinguished in the case of modular forms for the modular group by the vanishing in the Fourier series expansion see q expansion q expansion math Sigma a n q n math of the constant coefficient a sub 0 sub . This Fourier expansion exists as a consequence of the presence in the modular group s action on the upper half plane of the transformation math z mapsto z 1. math For other groups, there may be some translation through several units, in which case the Fourier expansion is in terms of a different parameter. In all cases, though, the limit as q &rarr 0 is the limit in the upper half plane as the imaginary part of z &rarr &infin . Taking the quotient by the modular group, say, this limit corresponds to a cusp of a modular curve in the sense of a point added for compactification mathematics compactification . So, the definition amounts to saying that a cusp form is a modular form that vanishes at a cusp. In the case of other groups, there may be several cusps, and the definition becomes a modular form vanishing at all cusps. This may involve several expansions. The dimensions of spaces of cusp forms are in principle computable, via the Riemann Roch theorem . For example, the famous Ramanujan function &tau n arises as the sequence of Fourier coefficients of the cusp form of weight 12 for the modular group, with a sub 1 sub 1. The space of such forms has dimension 1, which means this definition is possible and that accounts for the action of Hecke operator s on the space being by scalar multiplication Mordell s proof of Ramanujan s identities .

Multiple issues expert January 2011 lead rewrite January 2011 The Lewis offset is a term for the portion of the central groove on a permanent mandibular first molar which lies between the two central pits. It lies at an angle to the mesio distal axis of the tooth, and causes the mesial portion of the central groove to be located further buccally than the distal portion. This bucco lingual shift correlates with a relative difference in size between the mesial and distal cusps on these teeth the mesiolingual cusp is larger than the mesiobuccal cusp, but the distobuccal cusp is larger than the distolingual cusp. It also allows for the buccal groove to be located mesial to the lingual groove which is mandatory to accommodate the relative sizes of the three cusps on the buccal and two cusps on the lingual of the occlusal surface of the tooth.

It marks the angular house fourth house Cusp astrology cusp in most House astrology house systems this is reversed in the southern hemisphere . Astrological significance The Imum Coeli is said to refer to our roots and also to the least conscious part of ourselves. It symbolizes foundations, beginnings in life, what may have been experienced through parental inheritance and homeland influences, need for security and relationships with the home and family life. It also may describe the circumstances that we will encounter at the end of our lives. Because this house was the most distant point possible from the visible part of the horoscope , Hellenistic astrologers considered the IC to be the home of the underworld, or Hades . In many cases the IC refers to a parent &mdash traditionally, the father . Modern astrologers may use the IC as a significator for the mother , or for both parents. There is no consensus in modern usage for which parent is best represented by the IC. The point is moot for Hellenistic astrologers who considered the Angular house fourth house the house of the father, but did not use the Imum Coeli as the cusp of the fourth house. Using the natural houses system see cadent houses and modern quadrant house systems in which the IC is the cusp of the Angular house fourth house , some modern astrologers see a correspondence between the fourth house and the astrological sign Cancer . However, traditional astrologers, using whole sign houses, never made this connection.
