Upsilon Serial Number
Maija
The name of the letter was originally just "υ" (y; also called hy, hence "hyoid", meaning "shaped like the letter υ"), but the name changed to "υ ψιλόν" u psilon 'plain υ' to distinguish it from οι, which had come to have the same [y] pronunciation.[7]
In early Attic Greek (6th century BCE), it was pronounced [u] (a close back rounded vowel like the English "long o͞o").[8][9] In Classical Greek, it was pronounced [y] (a close front rounded vowel), at least until 1030.[10] In Modern Greek, it is pronounced [i]; in the digraphs αυ and ευ, as [f] or [v]; and in the digraph ου as [u]. In ancient Greek, it occurred in both long and short versions, but Modern Greek does not have a length distinction.
The usage of Y in Latin dates back to the first century BC. It was used to transcribe loanwords from Greek, so it was not a native sound of Latin and was usually pronounced /u/ or /i/. The latter pronunciation was the most common in the Classical period and was used mostly by uneducated people. The Roman Emperor Claudius proposed introducing a new letter into the Latin alphabet to transcribe the so-called sonus medius (a short vowel before labial consonants), but in inscriptions, the new letter was sometimes used for Greek upsilon instead.
For they say that the course of human life resembles the letter Y, because every one of men, when he has reached the threshold of early youth, and has arrived at the place "where the way divides itself into two parts," is in doubt, and hesitates, and does not know to which side he should rather turn himself.[15]
Number.EPSILON is the difference between 1 and the next greater number representable in the Number format, because double precision floating point format only has 52 bits to represent the mantissa, and the lowest bit has a significance of 2-52.
Note that the absolute accuracy of floating numbers decreases as the number gets larger, because the exponent grows while the mantissa's accuracy stays the same. Number.MIN_VALUE is the smallest representable positive number, which is much smaller than Number.EPSILON.
Any number encoding system occupying a finite number of bits, of whatever base you choose (e.g. decimal or binary), will necessarily be unable to represent all numbers exactly, because you are trying to represent an infinite number of points on the number line using a finite amount of memory. For example, a base-10 (decimal) system cannot represent 1/3 exactly, and a base-2 (binary) system cannot represent 0.1 exactly. Thus, for example, 0.1 + 0.2 is not exactly equal to 0.3:
For this reason, it is often advised that floating point numbers should never be compared with ===. Instead, we can deem two numbers as equal if they are close enough to each other. The Number.EPSILON constant is usually a reasonable threshold for errors if the arithmetic is around the magnitude of 1, because EPSILON, in essence, specifies how accurate the number "1" is.
However, Number.EPSILON is inappropriate for any arithmetic operating on a larger magnitude. If your data is on the 103 order of magnitude, the decimal part will have a much smaller accuracy than Number.EPSILON:
In addition to magnitude, it is important to consider the accuracy of your input. For example, if the numbers are collected from a form input and the input value can only be adjusted by steps of 0.1 (i.e. ), it usually makes sense to allow a much larger tolerance, such as 0.01, since the data only has a precision of 0.1.
Note: Important takeaway: do not simply use Number.EPSILON as a threshold for equality testing. Use a threshold that is appropriate for the magnitude and accuracy of the numbers you are comparing.

Gamma Theta Upsilon, or GTU, is an international honor society in geography. GTU was founded in 1928 and became a national organization in 1931. Members of GTU have met academic requirements and share a background and interest in geography. GTU chapter activities support geographic knowledge and awareness on a number of college and university campuses. The VU chapter of GTU, Alpha Xi, was established on campus in May, 1950. Currently, Prof. Longan is the VU GTU faculty sponsor.
To be eligible for GTU membership, students must 1) have completed a minimum of three geography courses, 2) have a GPA of 3.3 overall and in geography, and 3) shall have completed at least 3 semesters or 5 quarters of college course work.
In 2021, Phi Delta Theta introduced recruitment challenge numbers for its chapters and emerging chapters to work towards as they recruited their Phikeia classes. The challenge numbers served as a data-driven benchmark and encouraged chapters to approach recruitment with a growth mindset to complete the challenge.
The Kappa Lambda chapter also sponsors an annual research award named after founding DCG dean, Dr. Judson C. Hickey, and an award for the best comprehensive patient case presentation by a senior. We also sponsor an award for a junior student that is selected by their classmates for their professional character, which is named after former chapter and national OKU president, Dr. Ralph McKinney.
Membership in OKU is by election. Each year we elect alumni members from the graduating senior class. To be eligible for membership, candidates must rank academically in the top 20% of their class. From this group, a number equal to 12% of the senior class may be voted into membership and inducted into OKU just prior to graduation.
Invitations for membership are based on GPA, extracurricular activities and professional conduct. Each year we also elect one honorary member who may or may not be a dentist, and two faculty members. Their election is based on significant contributions to the art and science of dentistry. To read more about OKU, please visit Supreme Chapter of Omicron Kappa Upsilon (OKU) website.
A banquet is held annually at the end of the school year to celebrate our new members. New members are guests of OKU for an evening of dinner and recognition. This is an elegant evening in which new members are encouraged to invite guests and family to celebrate their induction.
Healthcare Professionals have specialized skills & knowledge, an obligation to life-long education, codes of ethical conduct, and a commitment to enhancing the greater community good or interest through service and leadership. Society empowers us in ways that very few other groups can imagine. Accordingly, we owe it to society to do right, give our best and be compassionate. OKU recognizes excellence in scholarship and character in the dental profession.
The Kappa Lambda Chapter of Omicron Kappa Upsilon, the national dental honor society, held its 50 th annual convocation on Thursday, April 27 at the Pinnacle Club in downtown Augusta. Eleven alumni members from the DCG Class of 2023, as well as two faculty member, Dr. Zoya Kurago, Department of Oral Biology and Dr. William R. Bachand, Department of Restorative Sciences, two life members, Dr. Michael B. Rodgers ( Emory V Class of 1969), and Dr. J. Wen Brown (DCG Class of 1985), one honorary member, Dr Emmanuel Ngoh were inducted. Alumni, honorary, and faculty members were presented the traditional OKU key their membership certificates and a stole.
In our Universe today, quarks are always bound together by gluons to form "composite" particles such as protons and neutrons. The Quark-Gluon Plasma, or QGP, often described as a soup-like medium, is a hot, dense state in which these quarks and gluons exist freely, unbound. This is thought to have been the situation a few millionths of a second after the Big Bang.
The Υ (Upsilon) particle, a quarkonium consisting of a bottom and an anti-bottom quark, exists in three states known as 1S, 2S and 3S, in decreasing order of how tightly the quarks are bound. (1S is the ground state of the Υ, while the others are excited states.) Because they are more loosely bound, the 2S and 3S states will melt more readily in the QGP. This means that the number of Υ(2S) and Υ(3S) particles produced relative to Υ(1S) in heavy-ion collisions should be less than corresponding numbers from proton collisions.
