[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 ... -
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 ... -
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 ... -
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 ... -
Jammed architectural structures: towards large-scale reversible construction
(Springer Berlin Heidelberg, 2016-04)This paper takes a first step in characterizing a novel field of research—jammed architectural structures—where load-bearing architectural structures are automatically aggregated from bulk material. Initiated by the group ... -

Jamming of Knots along a Tensioned Chain
(American Chemical Society (ACS), 2016-01)We examine the motion of a knot along a tensioned chain whose backbone is corrugated due to excluded volume effects. At low applied tensions, the knot traverses the chain diffusively, while at higher tensions the knot makes ... -
Jamming transition and emergence of fracturing in wet granular media
(American Physical Society (APS), 2020-04)We study fluid-induced deformation of granular media, and the fundamental role of capillarity and wettability on the emergence of fracture patterns. We develop a hydromechanical computational model, coupling a “moving ... -
Jamming user interfaces: Programmable particle stiffness and sensing for malleable and shape-changing devices
(Association for Computing Machinery (ACM), 2012-10)Malleable and organic user interfaces have the potential to enable radically new forms of interactions and expressiveness through flexible, free-form and computationally controlled shapes and displays. This work, specifically ... -
jamSheets: Thin Interfaces with Tunable Stiffness Enabled by Layer Jamming
(Association for Computing Machinery (ACM), 2014-02)This works introduces layer jamming as an enabling technology for designing deformable, stiffness-tunable, thin sheet interfaces. Interfaces that exhibit tunable stiffness properties can yield dynamic haptic feedback and ... -
Janus Emulsion Biosensors for Anti-SARS-CoV-2 Spike Antibody
