1911. Developmental aspects of Maximize Presupposition: a view from SlovenianPenka Stateva, invited lecture at foreign university Abstract: n this talk I will present the results of an experimental study of young children's acquisition and use of the pragmatic principle Maximize Presupposition in the context of the propositional attitude predicates (equivalent to) know and think. We use a felicity judgement task to test the ability of 5- and 7-year-old Slovenian-speaking children to derive the factive presupposition of know and the pragmatic inference trigerred by think in accord with Maximize Presupposition. The older group of children outperformed the younger group in both conditions manifesting a ceiling performance, while the younger group showed a more mixed pattern. Our results suggest that the anti-factivity inference is mastered on a par with the ability to derive the presupposition of factivity, as predicted by contemporary pragmatic theories. The discussion will also touch upon questions about the influence of bilingualism on developing pragmatic abilities, negative transfer in the domain of pragmatics and its dependence on cross-linguistic morpho-syntactic variation among translational equivalents.

1912. Implicit water model within the Zimm-Bragg approach to analyze experimental data for heat and cold denaturation of proteinsArtem Badasyan, Sh. A. Tonoyan, Matjaž Valant, Jože Grdadolnik, 2021, original scientific article Abstract: Studies of biopolymer conformations essentially rely on theoretical models that are routinely
used to process and analyze experimental data. While modern experiments allow study of
single molecules in vivo, corresponding theories date back to the early 1950s and require an
essential update to include the recent significant progress in the description of water. The
Hamiltonian formulation of the Zimm-Bragg model we propose includes a simplified, yet
explicit model of water-polypeptide interactions that transforms into the equivalent implicit
description after performing the summation of solvent degrees of freedom in the partition
function. Here we show that our model fits very well to the circular dichroism experimental
data for both heat and cold denaturation and provides the energies of inter- and intra-
molecular H-bonds, unavailable with other processing methods. The revealed delicate
balance between these energies determines the conditions for the existence of cold dena-
turation and thus clarifies its absence in some proteins.
Keywords: protein folding, cold denaturation, water, Zimm-Bragg model

1917. Intercomparison and characterization of 23 Aethalometers under laboratory and ambient air conditions: : procedures and unit-to-unit variabilitiesAndrea Cuesta-Mosquera, Griša Močnik, Luka Drinovec, Thomas Müller, Sascha Pfeifer, Maria Cruz Minguillon, Björn Briel, Paul Buckley, Vadimas Dudoitis, Javier Fernández-García, 2021, original scientific article Abstract: Aerosolized black carbon is monitored worldwide to quantify its impact on air quality and climate. Given its importance, measurements of black carbon mass concentrations must be conducted with instruments operating in quality-checked and ensured conditions to generate data which are reliable and comparable temporally and geographically.
In this study, we report the results from the largest characterization and intercomparison of filter-based absorption photometers, the Aethalometer model AE33, belonging to several European monitoring networks. Under controlled laboratory conditions, a total of 23 instruments measured mass concentrations of black carbon from three well-characterized aerosol sources: synthetic soot, nigrosin particles, and ambient air from the urban background of Leipzig, Germany. The objective was to investigate the individual performance of the instruments and their comparability; we analyzed the response of the instruments to the different aerosol sources and the impact caused by the use of obsolete filter materials and the application of maintenance activities.
Differences in the instrument-to-instrument variabilities from equivalent black carbon (eBC) concentrations reported at 880 nm were determined before maintenance activities (for soot measurements, average deviation from total least square regression was −2.0 % and the range −16 % to 7 %; for nigrosin measurements, average deviation was 0.4 % and the range −15 % to 17 %), and after they were carried out (for soot measurements, average deviation was −1.0 % and the range −14 % to 8 %; for nigrosin measurements, the average deviation was 0.5 % and the range −12 % to 15 %). The deviations are in most of the cases explained by the type of filter material employed by the instruments, the total particle load on the filter, and the flow calibration.
The results of this intercomparison activity show that relatively small unit-to-unit variability of AE33-based particle light absorbing measurements is possible with well-maintained instruments. It is crucial to follow the guidelines for maintenance activities and the use of the proper filter tape in the AE33 to ensure high quality and comparable black carbon (BC) measurements among international observational networks.
