[J over ψ] polarization in p+p collisions at √s = 200 TeV in STAR
(Elsevier, 2014-10)We report on a polarization measurement of inclusive [J over ψ] mesons in the di-electron decay channel at mid-rapidity at 2<p[subscript T]<6 GeV/c in p+p collisions at √s = 200 GeV. Data were taken with the STAR detector ... -
J Waves of Osborn Revisited
(Elsevier, 2010-05)In 1953, Joseph Osborn examined the physiologic effects of hypothermia and defined typical associated changes in the electrocardiogram (ECG), now known as J waves of Osborn. There is a subtlety, however: Osborn's J waves ... -
The J%JOIN Package
(MIT Artificial Intelligence Laboratory, 1971-04-02)The J%JOIN program creates links between the elements of a set of line segments on the basis of their geometric proximity. According to the value of the third argument, (T or NIL), the program will either place a set of ... -
J. Locke, Op. Cit.: Invocations of Law on Snowy Streets
(Wildy, Simmonds and Hill Publishing, 2012-07)Each winter in the northern cities of the United States, a familiar scene illustrates tacit and deeply sedimented, yet common invocations of law. After a heavy snow storm, one can see old chairs, traffic cones, milk crates, ... -
J/psi production at high transverse momenta in p plus p and Cu plus Cu collisions at [sqrt] s(NN)=200 GeV
(American Physical Society, 2009-10)The STAR Collaboration at the Relativistic Heavy Ion Collider presents measurements of J/psi-->e+e- at midrapidity and high transverse momentum (pT>5 GeV/c) in p+p and central Cu+Cu collisions at [sqrt]sNN=200 GeV. The ... -
J/ψ and ψ(2S) production in pp collisions at √s = 7 Tev
(Springer Berlin Heidelberg, 2012-02)A measurement of the J/ ψ and ψ (2S) production cross sections in pp collisions at √s = 7TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 pb ⁻¹. Using a fit ... -
J/ψ Production at High Transverse Momenta in P+p and Au + Au Collisions at √SNN=200 GeV
(Elsevier BV, 2013-05)We report J/ψ spectra for transverse momenta p[subscript T]> 5GeV/c at mid-rapidity in p+p and Au+Au collisions at √sNN=200GeV. The inclusive J/ψ spectrum and the extracted B-hadron feed-down are compared to models ... -
J/ψ Production at Low p[subscript T] in Au + Au and Cu + Cu Collisions at √s[subscript NN] = 200 GeV with the STAR Detector
(American Physical Society, 2014-08)The J/ψ p[subscript T] spectrum and nuclear modification factor (R[subscript AA]) are reported for p[subscript T] < 5GeV/c and |y| < 1 from 0% to 60% central Au + Au and Cu + Cu collisions at √s[subscript NN] = 200 GeV at ... -
J/ψω decay channel of the X(3872) charm meson molecule
(American Physical Society, 2013-07)Analyses of the J/ψπ[superscript +]π[superscript -] decay channel of the X(3872) resonance by the CDF, Belle, and LHCb Collaborations have established its J[superscript PC] quantum numbers as 1[superscript ++]. An analysis ... -
Jack Tworkov's work from 1955 to 1979 : the synthesis of choice and chance
(Massachusetts Institute of Technology, 1981)Jack Tworkov began painting in the 1920s and made his reputation later as an Abstract Expressionist working in a gestural style. At the age of sixty-five Tworkov put that reputation on the line by undergoing a radical ... -

Jacobi-Trudi Determinants over Finite Fields
(Springer International Publishing, 2018-07-16)Abstract In this paper, we work toward answering the following question: given a uniformly random algebra homomorphism from the ring of symmetric functions over ... -
Jacobian-based control of soft robots for manipulation using implicit surface models
(Massachusetts Institute of Technology, 2017)Soft robot hands offer numerous advantages over rigid ones for manipulation, including robustness and safety. Yet, compared to rigid robots, soft robots are characterized by continuous mechanics, and finite-element ... -
Jacobians of Noncommutative Motives
(Independent University of Moscow, 2014-07)In this article one extends the classical theory of (intermediate) Jacobians to the “noncommutative world”. Concretely, one constructs a Q-linear additive Jacobian functor N → J(N) from the category of noncommutative Chow ... -
JAK inhibition in a patient with a STAT1 gain-of-function variant reveals STAT1 dysregulation as a common feature of aplastic anemia
(Elsevier BV, 2022)BACKGROUND: Idiopathic aplastic anemia is a potentially lethal disease, characterized by T cell-mediated autoimmune attack of bone marrow hematopoietic stem cells. Standard of care therapies (stem cell transplantation or ... -
JAK2 V617F stimulates proliferation of erythropoietin-dependent erythroid progenitors and delays their differentiation by activating Stat1 and other nonerythroid signaling pathways
(Elsevier, 2016-07)JAK2 V617F is a mutant-activated JAK2 kinase found in most polycythemia vera (PV) patients; it skews normal proliferation and differentiation of hematopoietic stem and progenitor cells and simulates aberrant expansion of ... -
JAK2/IDH-mutant–driven myeloproliferative neoplasm is sensitive to combined targeted inhibition
(American Society for Clinical Investigation, 2018-04)Patients with myeloproliferative neoplasms (MPNs) frequently progress to bone marrow failure or acute myeloid leukemia (AML), and mutations in epigenetic regulators such as the metabolic enzyme isocitrate dehydrogenase ... -
A jam-resistant CubeSat communications architecture
(Massachusetts Institute of Technology, 2017)This thesis proposes a communications system that utilizes the benefits of CubeSats to provide jam-resistant communications. The growth of CubeSats within educational communities has prompted their use in industry; both ... -
