Size Matters More Than Chemistry for Cloud-Nucleating Ability of Aerosol Particles
2006
Size-resolved cloud condensation nuclei (CCN) spectra measured for various aerosol types at a non-urban site in Germany showed that CCN concentrations are mainly determined by the aerosol number size distribution. Distinct variations of CCN activation with particle chemical composition were observed but played a secondary role. When the temporal variation of chemical effects on CCN activation is neglected, variation in the size distribution alone explains 84 to 96% of the variation in CCN concentrations. Understanding that particles' ability to act as CCN is largely controlled by aerosol size rather than composition greatly facilitates the treatment of aerosol effects on cloud physics in re…
Bioetyki kulturowe w Ameryce Łacińskiej
2017
W artykule została przedstawiona charakterystyka bioetyki łacińskiej, jej korzenie i geneza, rozwój w poszczególnych, wybranych krajach, a także typowa problematyka. Bioetyka łacińska u swych początków jako dyscyplina akademicka czerpała głównie ze Stanów Zjednoczonych. Niewspółmierność problematyki paradygmatów bioetyki zachodniej do realiów krajów łacińskich doprowadziła do przewartościowania i prób wypracowania własnej, swoistej, bardziej adekwatnej bioetyki kulturowej.
Architetture del divenire. Innovazioni contemporanee/Emerging Architecture. Contemporary Innovations (presentazione di Giuseppe Pellitteri) - Quadern…
2014
La posizione assunta dall'architettura all'inizio del ventunesimo secolo è ambigua e così la forma degli edifici che ambiscono a convogliare significati. Il processo di radicale trasformazione dell’architettura, avvenuto sin dal primo Novecento, quale conseguenza della graduale sostituzione delle tecniche edilizie tradizionali con le tecniche “moderne”, ha subito un notevole slancio nell'ultimo ventennio, per effetto del crescente mutamento tecnologico. I materiali, le tecniche costruttive e l’innovazione tecnologica hanno condizionato sensibilmente ed irreversibilmente il pensiero architettonico, producendo in questi ultimi anni nuove espressività linguistiche del tutto “insolite” rispetto…
"Selection efficiency" of "Search for $B^{+}\to K^{+}\nu\bar{\nu}$ decays using an inclusive tagging method at Belle II"
2022
Signal efficiency as a function of the dineutrino invariant mass squared $q^{2}$ for events in the signal region (SR) ($\rm{BDT}_{1} > 0.9$ and $\rm{BDT}_{2} > 0.95$). The error bars indicate the statistical uncertainty.
"Expected and observed limit" of "Search for $B^{+}\to K^{+}\nu\bar{\nu}$ decays using an inclusive tagging method at Belle II"
2022
CL$_{s}$ value as a function of the branching fraction of $B^{+} \rightarrow K^{+} \nu \bar{\nu}$ for expected and observed signal yields and the corresponding upper limits at 90% confidence level (CL). The expected limit is derived for the background-only hypothesis. The observed limit is derived from a simultaneous fit to the on-resonance and off-resonance data, corresponding to an integrated luminosity of 63 fb$^{−1}$ and 9 fb$^{−1}$, respectively.
Evaluating Safety Systems for Machine Tools with Computer Numerical Control using Analytic Hierarchy Process
2019
Computer numerical control (CNC) machine tools are complex production systems with fully automatic machine parts. Nowadays, high feed rates and machining speeds are used during the machining process. Human operators are still needed to set-up the machine, load/unload workpieces and parts, load the machining code, and supervise the machining process. The operators work in an environment where automated high-speed motions occur, and consequently, CNC machine tools have to be equipped with safety systems. The approach presented in this paper was to evaluate the main safety systems of CNC machine tools based upon the analytic hierarchy process (AHP). The analyzed systems were divided into six m…
"Postfit yields Y(4S)" of "Search for $B^{+}\to K^{+}\nu\bar{\nu}$ decays using an inclusive tagging method at Belle II"
2022
Yields in on-resonance data and as predicted by the simultaneous fit to the on- and off-resonance data, corresponding to an integrated luminosity of 63 and 9 fb$^{−1}$, respectively. The predicted yields are shown individually for charged and neutral B-meson decays and the five continuum background categories. The leftmost three bins belong to the first control region (CR1) with BDT$_{2} \in [0.93; 0.95]$ and the other nine bins correspond to the signal region (SR), three for each range of BDT$_{2} \in [0.95; 0.97; 0.99; 1.0]$. Each set of three bins is defined by $p_{T}(K^{+}) \in [0.5; 2.0; 2.4; 3.5] \rm{GeV}/c^{2}$.

2022
Yields in off-resonance data and as predicted by the simultaneous fit to the on- and off-resonance data, corresponding to an integrated luminosity of 63 and 9 fb$^{−1}$, respectively. The predicted yields are shown individually for the five continuum background categories. The leftmost three bins belong to the third control region (CR3) with BDT$_{2} \in [0.93; 0.95]$ and the other nine bins correspond to the second control region (CR2), three for each range of BDT$_{2} \in [0.95; 0.97; 0.99; 1.0]$. Each set of three bins is defined by $p_{T}(K^{+}) \in [0.5; 2.0; 2.4; 3.5] \rm{GeV}/c^{2}$.
