Finite-temperature bubble nucleation with shifting scale hierarchies
No full text[ENG]Data used to plot the figures presented in the paper "Finite-temperature bubble nucleation with shifting scale hierarchies'', arXiv:2503.13597.The .zip files contain data for all the plots of the paper. Each archive contains a folder corresponding to the associated plot from the paper. The naming convention of archives (and folders) follows the example:Figure 1 -> Fig1.zip -> Fig1/Fig1_scale_shifters_data.csv,i.e. name contains figure number and short description. In case of "multi-plot" figures the archive contains multiple files, for example:Figure 4 -> Fig4.zip ->Fig4/Fig4L_deltaTp_NLOdet_NLOdetT4_data.csv Fig4/Fig4R_deltaTp_NLOgrad_vs_NLOdetT4_data.csv,where "L" and "R" next to "Fig4" correspond to "left" and "right" panels of Fig4.The data inside the folders is stored in .csv format, with self-explanatory column headers. Names of the headers are written in a TeX-like convention and follow the notation used in the article.Note that the data here are "raw" and in order to recreate the plots visible in "Finite-temperature bubble nucleation with shifting scale hierarchies", one should use interpolation and a median filter for the relevant regions of the parameter space.</p

Soil erosion - runoff plots 2007-2009
No full textIn 2007-2009, soil erosion were measured using standard USLE plots (22.1 m long and 2 m wide) in 5 locations in Poland: 1 – Udziejek (Suwałki Lakeland, Polska NE), 2 – Storkowo (Drawskie Lakeland, Polska NW), 3 – Bogucin (Nałęczów Plateau, Polska SE), 4 – Guciów (Middle Roztocze, Polska SE), 5 - Łazy (Wiśnicz Foothils, Polska S).The measurements included: rainfall (P, mm), rainfall erosivity index (EI30, MJ mm ha-1 h-1), soil loss (SL, kg m-2) and runoff (mm) from plots with: bare fallow, cereals and root crops and, in two locations with grass. Plots were separated from the rest of the field and from each other by PCV borders. Surface runoff with eroded sediment was collected in tanks. The volume of water was measured, the selected sediment was dried and weighed. The amount of water and sediment was related to the unit area. Rainfall parameters were registered by automatic gauges located near the plots. Erosive rainfall events were identified using the USLE criterion (Wischmeier, Smith 1978). For rainfall events, kinetic energy Ekin was calculated according to the formula developed by Brown and Foster (1986) and then its EI30 index was calculated. Each row contains the measurement location, measurement date, rainfall depth, soil loss and runoff. For winter measurements, 1/10 of the combined rainfall and snowfall was considered as rainfall-runoff R-index. Measurements were taken after heavy rainfall or at least once a month. If the measurement period included more than one rainfall, the sum of rainfall was related to the sum of its erosivity. The measurements were listed by the dates they were taken. </p

Unveiling biohazard threats: molecular surveillance of D. repens, D. immitis, and A. reconditum in stray animals amidst military war in Ukraine - raw data
No full textThe study conducted molecular surveillance of nematode invasions from the genera Dirofilaria and Acanthocheilonema in stray dogs and cats from five war-affected regions of Ukraine. The aim was to assess the biological risk resulting from the lack of adequate prophylaxis in animals inhabiting conflict zones.A total of 457 blood samples (233 from dogs and 224 from cats) were collected from five Ukrainian cities: Lviv, Berdychiv, Zvenyhorodka, Sumy, and Kharkiv. Genomic DNA isolated from these blood samples was used to detect and differentiate infections caused by Dirofilaria repens, Dirofilaria immitis, and Acanthocheilonema reconditum using Real-Time PCR with species-specific oligonucleotides. The sensitivity of the applied method was also evaluated.The analysis included raw PCR data, such as Ct values, which were used for diagnosis and for generating figures presented in the publication. Additionally, PCR product sequences were deposited. The collected data also included information on the examined animals, such as age, sex, and body weight, which were subsequently used to analyze risk factors for filariasis in dogs.</p
Nanoscale resolved mapping of the dipole emission of hBN color centers with a scattering-type scanning near-field optical microscope
No full textThe experimental data presented is related to the article: I. Niehues, D. Wigger, K. Kaltenecker, A. Klein-Hitpass, P. Roelli, A.K. Dąbrowska, K. Ludwiczak, P. Tatarczak, J.O. Becker, R. Schmidt, M. Schnell, J. Binder, A. Wysmołek, and R. Hillenbrand (2025) Nanoscale resolved mapping of the dipole emission of hBN color centers with a scattering-type scanning near-field optical microscope. Nanophotonics 14(3): 335–342, https://doi.org/10.1515/nanoph-2024-0554Color centers in hexagonal boron nitride (hBN) are promising candidates as quantum light sources for future technologies. In this work, we utilize a scattering-type near-field optical microscope (s-SNOM) to study the photoluminescence (PL) emission characteristics of such quantum emitters in metalorganic vapor phase epitaxy grown hBN. On the one hand, we demonstrate direct near-field optical excitation and emission through interaction with the nanofocus of the tip resulting in a subdiffraction limited tip-enhanced PL hotspot. On the other hand, we show that indirect excitation and emission via scattering from the tip significantly increases the recorded PL intensity. This demonstrates that the tip-assisted PL (TAPL) process effiently guides the generated light to the detector. We apply the TAPL method to map the in-plane dipole orientations of the hBN color centers on the nanoscale. This work promotes the widely available s-SNOM approach to applications in the quantum domain including characterization and optical control.Files:Fig. 1:The file contains photoluminescence (PL) measurement data of a single color center obtained with an AFM tip.Fig. 2:The file includes PL maps of two different emitters measured in near-field scans.Fig. 3:The file includes a PL scan of multiple color centers within a 6 μm × 6 μm region, along with PL spectra of color centers measured with extended integration times of 5 s.Fig. 4:The file contains PL intensity maps (integrated peak area from fit) for different angles between illumination direction.</p
Evolution of the retrograde response to mitochondrial dysfunction in budding yeasts
No full textWe investigated the function and evolution of the retrograde (Rtg) mitonuclear signalling pathway by searching for the orthologs of relevant proteins encoded in the genomes of supphylum Saccharomycotina within the phylum Ascomycota. We also identified targets of the retrograde regulation in Candida albicans using EMSA. This dataset contains code and results of the evolutionary analyses as well as the supplementary figures.</p
