Supersolid phases of light in extended Jaynes-Cummings-Hubbard systems

Jaynes-Cummings-Hubbard lattices provide unique properties for the study of correlated phases as they exhibit convenient state preparation and measurement, as well as "in situ" tuning of parameters. We show how to realize charge density and supersolid phases in Jaynes-Cummings-Hubbard lattices in the presence of long-range interactions. The long-range interactions are realized by the consideration of Rydberg states in coupled atom-cavity systems and the introduction of additional capacitive couplings in quantum-electrodynamics circuits. We demonstrate the emergence of supersolid and checkerboard solid phases, for calculations which take into account nearest neighbour couplings, through a mean-field decoupling.Comment: 9 pages with 6 figures, accepted for publication in Physical Review

High performance microprocessor system for eddy current defectoscope measurement signal processing

This article shows principles of development of the eddy current defectoscope data acquisition system. It describes goals of development of this system and main requirements for its characteristics. Also on basis of these requirements possible implementation of the device was suggested

Effect of time and temperature on the profile of volatile compounds in beef processed by the Sous Vide method.

Sous vide is a term of French origin that means “under vacuum”. It is a cooking technique that preserves the integrity of food by heating it for long periods at relatively low temperatures [1]

Biosimilar G-CSF versus filgrastim and lenograstim in healthy unrelated volunteer hematopoietic stem cell donors

The World Marrow Donor Organization recommends original granulocyte-colony stimulating factor (G-CSF) for the mobilization of stem cells in healthy unrelated hematopoietic stem cell donors. We report the comparison of a biosimilar G-CSF (Zarzio) with two original G-CSFs (filgrastim and lenograstim) in mobilization in unrelated donors. We included data of 313 consecutive donors who were mobilized during the period from October 2014 to March 2016 at the Medical University of Warsaw. The primary endpoints of this study were the efficiency of CD34+ cell mobilization to the circulation and results of the first apheresis. The mean daily dose of G-CSF was 9.1 μg/kg for lenograstim, 9.8 μg/kg for biosimilar filgrastim, and 9.3 μg/kg for filgrastim (p < 0.001). The mean CD34+ cell number per microliter in the blood before the first apheresis was 111 for lenograstim, 119 for biosimilar filgrastim, and 124 for filgrastim (p = 0.354); the mean difference was even less significant when comparing CD34+ number per dose of G-CSF per kilogram (p = 0.787). Target doses of CD34+ cells were reached with one apheresis in 87% donors mobilized with lenograstim and in 93% donors mobilized with original and biosimilar filgrastim (p = 0.005). The mobilized apheresis outcomes (mean number of CD34+ cells/kg of donor collected during the first apheresis) was similar with lenograstim, biosimilar filgrastim, and filgrastim: 6.2 × 10⁶, 7.6 × 10⁶, and 7.3 × 10⁶, respectively, p = 0.06. There was no mobilization failure in any of the donors. Biosimilar G-CSF is as effective in the mobilization of hematopoietic stem cells in unrelated donors as original G-CSFs. Small and clinically irrelevant differences seen in the study can be attributed to differences in G-CSF dose and collection-related factors. Active safety surveillance concurrent to clinical use and reporting to donor outcome registry (e.g., EBMT donor outcome registry or WMDA SEAR/SPEAR) might help to evaluate the possible short- and long-term complications of biosimilar G-CSF

Efeito do tempo e temperatura na maciez e teores de colágeno de carne bovina processada pelo método Sous Vide.

Sous vide é um sistema de processamento em que o alimento embalado a vácuo é cozido por longos períodos de tempo em temperaturas mais baixas. O binômio tempo/temperatura pode influenciar na maciez da carne bovina, atributo considerado mais importante na aceitação do produto pelo consumidor. O objetivo deste trabalho foi avaliar o efeito do tempo e temperatura no processamento sous vide na maciez do corte bovino fraldinha (Obliquus abdominis internus). Neste experimento, foram testadas as combinações de três tempos (60 min, 90 min e 120 min) e três temperaturas (65ºC, 75ºC e 85ºC) para cocção da carne bovina pelo método sous vide. As amostras foram analisadas quanto a perda por cocção, força de cisalhamento, colágeno total, solúvel e insolúvel. Observou-se o aumento da perda por cocção enquanto que não foi observada diferença estatística (p>0,05) para força de cisalhamento da carne do corte fraldinha. Houve diferença significativa (p<0,05) entre as combinações de temperatura x tempo para as frações de colágeno. As combinações de tempo e temperatura estudadas não afetaram a maciez da carne do corte fraldinha, apesar de apresentar teores de colágeno total e solúvel diferentes entre os tratamentos

Casuarina glauca prenodule cells display the same differentiation as the corresponding nodule cells

Recent phylogenetic studies have implied that all plants able to enter root nodule symbioses with nitrogen-fixing bacteria go back to a common ancestor (D.E. Soltis, P.S. Soltis, D.R. Morgan, S.M. Swensen, B.C. Mullin, J.M. Dowd, and P.G. Martin, Proc. Natl. Acad. Sci. USA, 92:2647-2651, 1995). However, nodules formed by plants from different groups are distinct in nodule organogenesis and structure. In most groups, nodule organogenesis involves the induction of cortical cell divisions. In legumes these divisions lead to the formation of a nodule primordium, while in non-legumes they lead to the formation of a so-called prenodule consisting of infected and uninfected cells. Nodule primordium formation does not involve prenodule cells, and the function of prenodules is not known. Here, we examine the differentiation of actinorhizal prenodule cells in comparison to nodule cells with regard to both symbionts. Our findings indicate that prenodules represent primitive symbiotic organs whose cell types display the same characteristics as their nodule counterparts. The results are discussed in the context of the evolution of root nodule symbiose
