TL;DR: Improved measurements of CP-violation parameters in B(0) --> phiK(0), eta(')K (0), KS (0)KS( 0)KS (0%) decays and an improved measurement of CP asymmetries is presented.
Abstract: We present improved measurements of $CP$-violation parameters in ${B}^{0}\ensuremath{\rightarrow}\ensuremath{\phi}{K}^{0}$, ${\ensuremath{\eta}}^{\ensuremath{'}}{K}^{0}$, ${K}_{S}^{0}{K}_{S}^{0}{K}_{S}^{0}$ decays based on a sample of $535\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB energy-asymmetric ${e}^{+}{e}^{\ensuremath{-}}$ collider. We obtain $\mathrm{sin} 2{\ensuremath{\phi}}_{1}^{\mathrm{eff}}=+0.64\ifmmode\pm\else\textpm\fi{}0.10(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.04(\mathrm{syst})$ for ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{K}^{0}$, $+0.50\ifmmode\pm\else\textpm\fi{}0.21(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.06(\mathrm{syst})$ for ${B}^{0}\ensuremath{\rightarrow}\ensuremath{\phi}{K}^{0}$, and $+0.30\ifmmode\pm\else\textpm\fi{}0.32(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.08(\mathrm{syst})$ for ${B}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}{K}_{S}^{0}$ decays. We have observed $CP$ violation in the ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}^{\ensuremath{'}}{K}^{0}$ decay with a significance of 5.6 standard deviations. We also perform an improved measurement of $CP$ asymmetries in ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{0}$ decays and obtain $\mathrm{sin} 2{\ensuremath{\phi}}_{1}=+0.642\ifmmode\pm\else\textpm\fi{}0.031(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.017(\mathrm{syst})$.

TL;DR: In this article, a supercritical fluid extraction of chamomile flower heads was performed on semi continuous extraction apparatus in the lab scale using carbon dioxide as solvent, and the results of high pressure experiments were compared with those obtained with Soxhlet extraction, steam distillation and maceration.
Abstract: Supercritical fluid extraction of chamomile flower heads was performed on semi continuous extraction apparatus in the lab scale using carbon dioxide as solvent. The results of high pressure experiments were compared with those obtained with Soxhlet extraction, steam distillation and maceration. The obtained extracts were analysed by HPLC on α-bisabolol, matricine and chamazulene content and by gravimetrical method on essential oil and waxes content. The highest content of active components in extracts and highest extraction yield were obtained using SFE at 250 bar and 40 °C. At this extraction conditions the two step separation was used to optimize the separation of essential oil from unwanted components. Dynamic behaviour of the SFE with single step separation runs were analysed using two mathematical models for describing the constant rate period and subsequent falling rate period. Based on the experimental data, external mass transfer coefficient, diffusion coefficient and diffusivity in solid phase were estimated. Results showed acceptable agreement of calculated and experimental data. Based on the parameters determined in the lab scale the extraction process was successfully transferred to pilot scale.

TL;DR: The aim of this paper is to study the dynamics and complexity in a fractional-order financial system with time delays and observes fascinating transitions to deterministic chaos, including cascading period doubling, as well as high levels of complexity.
Abstract: Finance and economics are complex nonlinear systems that are affected by various external factors, including of course human action, bilateral relations, conflicts, and policy. Time delays in a financial system take into account the amount of time that passes from a particular policy or decision being made to it actually taking effect. It is thus important to consider time delays as an integral part of modeling in this field. Moreover, many features of financial systems cannot be expressed sufficiently precisely by means of integer-order calculus. Fractional-order calculus alleviates these shortcomings. The aim of this paper is therefore to study the dynamics and complexity in a fractional-order financial system with time delays. We observe fascinating transitions to deterministic chaos, including cascading period doubling, as well as high levels of complexity. This is particularly true in response to variations of derivative orders, which are thus identified as key system parameters.

TL;DR: This research analyzes well-documented political corruption scandals in Brazil over the past 27 years, focusing on the dynamical structure of networks where two individuals are connected if they were involved in the same scandal.
Abstract: Corruptive behaviour in politics limits economic growth, embezzles public funds, and promotes socio-economic inequality in modern democracies. We analyse well-documented political corruption scandals in Brazil over the past 27 years, focusing on the dynamical structure of networks where two individuals are connected if they were involved in the same scandal. Our research reveals that corruption runs in small groups that rarely comprise more than eight people, in networks that have hubs and a modular structure that encompasses more than one corruption scandal. We observe abrupt changes in the size of the largest connected component and in the degree distribution, which are due to the coalescence of different modules when new scandals come to light or when governments change. We show further that the dynamical structure of political corruption networks can be used for successfully predicting partners in future scandals. We discuss the important role of network science in detecting and mitigating political corruption.
