The ITEP-PNPI collaboration presents new results of the measurements of the spin rotation parameter A in the elastic scattering of negative pions on protons at Pbeam = 1.43 GeV/c. The results are compared to the predictions of several partial wave analyses. The experiment was performed at the ITEP proton synchrotron, Moscow.

The ITEP-PNPI collaboration presents the results of the measurements of the spin rotation parameter A in the elastic scattering of positive and negative pions on protons at Pbeam = 1.62 GeV/c. The setup included a longitudinally-polarized proton target with superconductive magnet, multiwire spark chambers and a carbon polarimeter with thick filter. Results are compared to the predictions of par...

Introduction Contrary to expectations based on the immuno-compromised clinical phenotype of the PNP-deficient patients, the present study demonstrates that PNP inhibitors (PNPi) can activate immune cells that can help mount a robust antitumor response. PNP deficiency in humans lead to elevation of plasma guanosine [1]. In the present study, we demonstrate that guanosine can activate toll like r...

Changes in pollution pressure exerted on the Rocha River Bolivia from diffuse sources were assessed using potential non-point indexes (PNPI) for 1997 and 2017. PNPI is a simple, low-effort, time- resource-saving method suitable data-scarce regions, as it works at catchment level with commonly available geographical data. Land use type (obtained by Landsat imagery classification), runoff (determ...

Production of p-wave pions in nucleon-nucleon collisions is studied according to an improved power counting that embodies the constraints of chiral symmetry. Contributions from the first two nonvanishing orders are calculated. We find reasonable convergence and agreement with data for a spin-triplet cross section in pp-->pppi(0), with no free parameters. Agreement with existing data for a spin-...
