Vanishing of self-extensions over symmetric algebras [PDF]
, 2013 We study self-extensions of modules over symmetric artin algebras. We show that non-projective modules with eventually vanishing self-extensions must lie in AR components of stable type $\mathbb{Z}A_{\infty}$. Moreover, the degree of the highest non-vanishing self-extension of these modules is determined by their quasilength.

Nucleoside-dependent synthesis of organic phosphorus compounds by rat liver nuclei [PDF]
, 1967 a) A modified procedure of the WIDNELL and TATA8 method yields rat liver nuclei manifesting a high degree of purity and activity. b) These nuclei contain a nucleoside-dependent phosphorylating activity that is readily released and apparently unrelated to

Circulating Human Neonatal Naïve B cells are Deficient in CD73 Impairing Purine Salvage
Frontiers in Immunology, 2016 Background: Extracellular purines, in particular adenosine (Ado) and adenosine-triphosphate (ATP), are critical immunoregulatory molecules. Expression and activity of purine ecto-enzymes on B cells in neonatal and adult blood may influence their function

Lie Markov models with purine/pyrimidine symmetry [PDF]
arXiv, 2012 Continuous-time Markov chains are a standard tool in phylogenetic inference. If homogeneity is assumed, the chain is formulated by specifying time-independent rates of substitutions between states in the chain. In applications, there are usually extra constraints on the rates, depending on the situation.

Purine nucleoside phosphorylase in chronic lymphocytic leukemia (CLL) [PDF]
Blood, 1978 Purine nucleoside phosphorylase (PNP), the enzyme schematically next to adenosine deaminase in the purine salvage pathway, has been demonstrated cytochemically in peripheral blood lymphocytes of healthy subjects and chronic lymphocytic leukemia (CLL) patients. The enzyme activity is confined to the cytosol.

Purine nucleoside phosphorylase (PNP) deficiency: across-the-board severe combined immunodeficiency
Egyptian Journal of Medical Human GeneticsBackground Purine nucleoside phosphorylase (PNP) deficiency is a rare, autosomal recessive, inborn error of immunity. It is characterized by progressive immune abnormalities ranging from severe combined immunodeficiency (SCID) to combined ...

Purine: A bi-graph based deep learning framework [PDF]
arXiv, 2014 In this paper, we introduce a novel deep learning framework, termed Purine. In Purine, a deep network is expressed as a bipartite graph (bi-graph), which is composed of interconnected operators and data tensors. With the bi-graph abstraction, networks are easily solvable with event-driven task dispatcher.

Transport in hybrid electronic devices based on a modified DNA nucleoside (deoxyguanosine) [PDF]
arXiv, 2000 We report on a new class of hybrid electronic devices based on a DNA nucleoside (deoxyguanosine lipophilic derivative) whose assembled polymeric ribbons interconnect a submicron metallic gate. The device exhibits large conductivity at room temperature, rectifying behaviour and strong current-voltage hysteresis.
