“…Analog readout of the CGEM detector enables the use of charge-centroid and µTPC methods to improve resolution up to at least 130 µm and allows loosening of the strip pitch to 650 µm, reducing the total number of channels to about 10,000. To fulfill this purpose, a dedicated front-end ASIC, 11 providing charge and time measurements and featuring a fully digital output, has been designed, taking into account the specific inputsignal characteristics of the BES III CGEM detector. It should operate with an input dynamic range between 1 and 50 fC, a sensor capacitance of up to 100 pF (depending on strip length), a power consumption within 10 mW/channel, and an event rate of 60 kHz/channel.…”

A new inner tracker based on a cylindrical gas electron-multiplier detector is under development to replace the current inner drift chamber of the BES III spectrometer. The BES III experiment is carried out at the BEPC II e[Formula: see text]e[Formula: see text] collider in Beijing at center-of-mass energies in the tau-charm region with a design luminosity of 1.0 [Formula: see text] 10[Formula: see text] cm[Formula: see text]s[Formula: see text]. The new inner tracker consists of three cylindrical layers of triple GEM surrounding the interaction point, covering 93% of solid angle. To fulfill physics requirements, a spatial resolution of 130 μm must be achieved. Both planar and cylindrical prototypes have been built and tested. A custom ASIC using UMC 110-nm technology has been designed to provide charge and time measurements—the first prototype is in testing. Notable and innovative aspects of the new inner tracker and the performance of the detector prototypes and readout ASIC are reported here.

The basic analytical forms for the deuteron wave function (DWF) in coordinate representation have been reviewed. The asymptotic behaviors of DWF near the origin of coordinates have been analyzed. New analytical forms DWF as a product of exponential function r n by the sum of the exponential terms A i *exp(-a i * r 3 ) are applied for calculation polarization characteristics of the deuteron. Numerical calculations have been done for realistic phenomenological potential Nijmegen groups -Reid93. In paper the results of angular asymmetry for deuteron vectort 10 , t 11 and tensort 20 , t 21 , t 22 polarizations are submitted. Except for angular asymmetry, is present as well momentum asymmetry for deuteron vector t 1i polarizations. Influence of approximation DWF in coordinate representation on the subsequent results of calculations tensor polarization t 20 is investigated. Comparison of values t 20 is made at θ=70 degree if to apply four different approximations DWF for same NN potential Reid93. At comparison of the received theoretical values t 20 with experimental data of world collaborations and reviews the good coordination for area of values momentum p=1-4 fm −1 is observed. Within the framework of a method of invariant amplitude have been calculated spin observables in backward elastic dp-scattering -tensor analyzing power T 20 and polarization transfer κ 0 . Are compared values for κ 0 and correlation κ 0 − T 20 with experimental data's. In a wide range of momentums p and angles θ scattering have been presented asymmetry for tensor analyzing power T 20 and T 22 , which characterize photoproduction for negative π-meson from deuteron in reaction γ(d,π − )pp. Symmetry of values T 20 and T 22 concerning a angle 90 degree is observed. Ratio R for vector P x and tensor P xz polarizations is characterized by angular asymmetry. So, near to "A y puzzle" remain actual theoretical and experimental researches of other polarization characteristics for processes at participation deuteron for which is present both angular, and momentum asymmetry. The obtained results of the deuteron vector and tensor polarizations t ij (p) give some information about the electromagnetic structure of the deuteron and the differential cross section of double scattering.Аналiтичнi форми хвильової функцiї i асиметрiя поляризацiйних характеристик дейтрона В.I.

Objectives. Rheumatoid arthritis affects about 1% of the world’s population. This is a chronic autoimmune disease. It is predominant in females with progressive joint damage. Immune cells are involved, especially Th1/Th17 lymphocytes and their inflammatory cytokines. These proteins have different functions in the immune system, such as IL-16 is a chemotactic factor; IL-18 can activate NFκB transcription producing inflammatory proteins; IL-31 can activate the JAK/STAT pathway which leads to the production of inflammatory factors in chronic diseases; IL-33 promotes IL-16 secretion which causes lymphocyte recruitment, and IL-32 and IL-34 appear to increase TNF secretion by macrophages activation in AR. The aim of this study was to evaluate serum levels of IL-16, IL-18, IL-31, IL-32, IL-33, and IL-34 and compare them with the severity and treatment of RA patients if there are any correlations. Methods. A total of 140 RA patients and 40 healthy donors were recruited from the Department of Rheumatology at Hospital das Clínicas from the Federal University of Pernambuco. 60 AR patients were naïve for any treatment. Serum cytokine levels were determined using an ELISA kit. Results. Serum IL-16 ( p = 0.0491), IL-18 ( p < 0.0001), IL-31 ( p = 0.0004), and IL-32 ( p = 0.0040) levels were significantly increased in RA patients compared with healthy donors. It was observed that patients using leflunomide had the lowest IL-18 levels, close to controls levels ( p = 0.0064). Conclusion. IL-16, IL-18, IL-31, and IL-32 are increased in the serum of RA patients. IL-18 is at lower levels in those AR who are taking leflunomide as treatment.
