Investigating Neutron Polarizabilities through Compton Scattering on 3^3He

We examine manifestations of neutron electromagnetic polarizabilities in coherent Compton scattering from the Helium-3 nucleus. We calculate $\gamma ^3$He elastic scattering observables using chiral perturbation theory to next-to-leading order (${\mathcal O}(e^2 Q)$). We find that the unpolarized differential cross section can be used to measure neutron electric and magnetic polarizabilities, while two double-polarization observables are sensitive to different linear combinations of the four neutron spin polarizabilities. [Note added in 2018] An erratum for this paper has been posted as arXiv:1804.01206. Overall conclusions are unchanged, but quantitative results are affected appreciably.Comment: 4 pages, 4 figures; version published in Phys. Rev. Let

The Dramatic Function of the Gravediggers\u27 Scene in Hamlet

It is unfortunate that one of the scenes most often cut from contemporary productions of Hamlet is the first scene of Act V, the gravediggers\u27 scene. The scene is, after all, static; it is merely a lyrical passage which seems, at first, to delay the movement of the drama, and, at all events, to add nothing to it. The producer wants swift, forward-moving action, and, certainly, he finds little enough of what he wants in the almost perverse, but always fundamental, deliberateness of this play. Consequently, one of the first scenes to be eliminated is almost invariably this one, despite its trenchant, laconic prose, its macabre humor, and its mordant, cynical philosophy of ultimate disillusion. The scene, in itself, as a separate entity, is probably one of the most famous in Shakespeare. Certainly it contains the most often misquoted line in English literature ( Alas, poor Yorick, I knew him, Horatio. ), as well as one of the funniest ( \u27Twill not be seen in him there (England); there the men are as mad as he. ). Perhaps the contemporary producer is short-sighted in cutting out the gravediggers\u27 scene; perhaps it does contribute, very definitely, to the tragedy, apart from its intrinsic excellence

Human~Divine Communication as a Paradigm for Power: al-Tha'labi's Presentation of Q. 38:24 and Q. 38:34

Verse 24 to 25 of sura 38 (Sad) of the Qur'an tell us 'David realized that We had been testing him, so he asked forgiveness of his Lord, fell down on his knees, and repented: We forgave him [his misdeed]. His reward will be nearness to Us, a good place to return to'; verse 34 to 35 of the same sura tell us 'We certainly tested Solomon, reducing him to a mere skeleton on the throne. He turned to Us and prayed: 'Lord, forgive me! Grant me such power as no one after me will have -- You are the Most Generous Provider', then, at verse 40, 'His reward will be nearness to Us, a good place to return to'. Yet the medieval Muslim historiographical tradition presents very different narratives, and very different personalities, in elucidation of these two episodes. The two questions that will be addressed in this essay are: restricting our focus to communication patterns and how God is presented in the narrative, how do these two narratives differ? And, secondly, can we find reasons in the text of the Qur'anic passages themselves for why they differ

Lo, Q

Q Lo is a 45 year old transgender man, the son of two Chinese immigrants who grew up in New York. Q discusses growing up as a queer person of color, how his gender and sexual identity was impacted by the lack of representation he saw around him, how his upbringing in Chinatown influenced his view of the world, and how his immigrant parents influenced his relationship with school, work and creativity. Q talks about attending college, dropping out of college, and his experiences going to MECA in Portland Maine while grappling with the classism and privilege he was experiencing from other students. Q reflects on the Michigan Women’s Festival, a festival controversial for its decision to bar transgender women from participating, and how he still reflects fondly on that time despite the controversy. Additionally, Q also talks about his current employment, and the various ways that performative actions have directly impacted his life, both in queer spaces and outside of them.https://digitalcommons.usm.maine.edu/querying_ohproject/1091/thumbnail.jp

Beware of MOOCs

Gerry Canavan, an assistant professor in the English department at Marquette University in Milwaukee, WI, shared his concerns about this new wave of e-learning with Higher Education Brief in this exclusive Q&A article. He said MOOCs are an ineffective medium for learning and that they de-skill and de-professionalize academia

Linear quantum addition rules

The quantum integer $[n]_q$ is the polynomial $1 + q + q^2 + ... + q^{n-1}.$ Two sequences of polynomials $\mathcal{U} = \{u_n(q)\}_{n=1}^{\infty}$ and $\mathcal{V} = \{v_n(q)\}_{n=1}^{\infty}$ define a {\em linear addition rule} $\oplus$ on a sequence $\mathcal{F} = \{f_n(q)\}_{n=1}^{\infty}$ by $f_m(q)\oplus f_n(q) = u_n(q)f_m(q) + v_m(q)f_n(q).$ This is called a {\em quantum addition rule} if $[m]_q \oplus [n]_q = [m+n]_q$ for all positive integers $m$ and $n$. In this paper all linear quantum addition rules are determined, and all solutions of the corresponding functional equations $f_m(q)\oplus f_n(q) = f_{m+n}(q)$ are computed.Comment: 8 pages; to appear in Integers: The Electronic Journal of Combinatorial Number Theor
