121. A device and a method for complete carbonaceous aerosol analysis in real time : European patent application EP4033242A1, 25. 8. 2021Asta Gregorič, Matic Ivančič, Martin Rigler, 2022, patent application Abstract: The present invention belongs to the field of methods and devices for analysing materials by determining their chemical or physical properties by the use of thermos-optical means. The invention relates to a device and a method for complete carbonaceous aerosol analysis in real time, which is essentially a system combining two different instruments, wherein the first instrument measures total carbon (TC) using flash heating of collected aerosol samples and generation of CO2, while the second instrument performs an optical attenuation analysis at 7 wavelengths from near UV (370 nm) to near IR range (950 nm) in order to characterize a Black Carbon (BC/EC) aerosols accumulated on a glass-fiber/PTFE filter tape. The device, i.e., the system of said instruments, collects and processes collected data of both instruments, wherein said processing may be performed by any of the instruments or by a separate processing means, computer or computer application.
Keywords: carbonaceous aerosol, black carbon, total carbon, brown carbon

122. Determining the Aethalometer multiple scattering enhancement factor C from the filter loading parameterLuca Ferrero, Niccolò Losi, Martin Rigler, Asta Gregorič, C. Colombi, L. D'Angelo, E. Cuccia, A. M. Cefalì, I. Gini, A. Doldi, 2024, original scientific article Abstract: Light-absorbing aerosols heat the atmosphere; an accurate quantification of their absorption coefficient is mandatory. However, standard reference instruments (CAPS, MAAP, PAX, PTAAM) are not always available at each measuring site around the world.
By integrating all previous published studies concerning the Aethalometers, the AE33 filter loading parameter, provided by the dual-spot algorithm, were used to determine the multiple scattering enhancement factor from the Aethalometer itself (hereinafter CAE) on an yearly and a monthly basis. The method was developed in Milan, where Aethalometer measurements were compared with MAAP data; the comparison showed a good agreement in terms of equivalent black carbon (R2 = 0.93; slope = 1.02 and a negligible intercept = 0.12 μg m−3) leading to a yearly experimental multiple scattering enhancement factor of 2.51 ± 0.04 (hereinafter CMAAP). On a yearly time base the CAE values obtained using the new approach was 2.52 ± 0.01, corresponding to the experimental one (CMAAP). Considering the seasonal behavior, higher experimental CMAAP and computed CAE values were found in summer (2.83 ± 0.12) whereas, the lower ones in winter/early-spring (2.37 ± 0.03), in agreement with the single scattering albedo behavior in the Po Valley.
Overall, the agreement between the experimental CMAAP and CAE showed a root mean squared error (RMSE) of just 0.038 on the CMAAP prediction, characterized by a slope close to 1 (1.001 ± 0.178), a negligible intercept (−0.002 ± 0.455) and a high degree of correlation (R2 = 0.955). From an environmental point of view, the application of a dynamic (space/time) determination of CAE increases the accuracy of the aerosol heating rate (compared to applying a fixed C value) up to 16 % solely in Milan, and to 114 % when applied in the Arctic at 80°N.

125. A hyperstructural approach to semisimplicityErgül Türkmen, Burcu Nİşancl Türkmen, Hashem Bordbar, 2024, original scientific article Abstract: In this paper, we provide the basic properties of (semi)simple hypermodules. We show that if a hypermodule M is simple, then (End(M), ·) is a group, where End(M) is the set of all normal endomorphisms of M. We prove that every simple hypermodule is normal projective with a zero singular subhypermodule. We also show that the class of semisimple hypermodules is closed under internal direct sums, factor hypermodules, and subhypermodules. In particular, we give a characterization of internal direct sums of subhypermodules of a hypermodule.

126. Sheffer stroke Hilbert algebras stabilizing by idealsTugce Katican, Hashem Bordbar, 2024, original scientific article Abstract: This manuscript aims to provide a new characterization of Sheffer stroke Hilbert algebras due to their ideals and proposes stabilizers. In the setup of the main results, we construct particular subsets of Sheffer stroke Hilbert algebras and we propose important properties of these subsets by investigating whether these sets are ideals or not. Furthermore, we investigate whether the introduced subsets of Sheffer stroke Hilbert algebras are minimal ideals. Afterward, we define stabilizers in a Sheffer stroke Hilbert algebra and obtain their set theoretical properties. As an implementation of the theoretical findings, we present numerous examples and illustrative remarks to guide readers.

130. Gender variation in indeclinable inanimate nouns and gender markedness in modern RussianKirill Chuprinko, Varvara Magomedova, Natalia Slioussar, 2023, original scientific article Abstract: Abstract
In this paper, the results of a large web-corpus study on gender of Russian inanimate indeclinable common nouns are presented. In most cases, neuter is assigned to indeclinables as a default. However, morphophonological and semantic analogy may lead to feminine and masculine gender assignment. An extensive variation is observed in the whole group of indeclinables and for particular words, which is much larger than anything that can be found in indeclinable nouns. These data support the idea that both masculine and neuter genders have a special status in the Russian gender system (Magomedova & Slioussar 2023). Masculine tends to be chosen in case of conflicting gender cues. When there are no strong cues pointing to any gender, neuter is assigned as the default option. The results of the study are hardly compatible with various structural approaches to gender assignment, but can be accounted for in competition-based models.
