The polarization switching in nanoscale with an anisotropic 2D magnetic semiconductor
No full textHere we present a proof-of-concept device demonstrating the feasibility to control the light polarization using the properties of the magnetic 2D materials. The studied structure consists of a diluted magnetic semiconductor quantum well and a thin layer of CrSBr. We show that by application of the external field we can switch the sign of the polarization of the emitted light. The theoretical modelling confirms that such a switching is a direct consequence of a collosal shift of the exciton lines observed in the high energy range of the CrSBr spectra. Owing to this mechanism, the full rotation of the polarization state can be realized in a layer as thin as few hundred nanometers.</p
The directions of spatial development of metropolitan areas in Poland
No full textThe “localities” vector layer contains localities from three Polish urban complexes (WMA, LMA and OAA) subjected to typology derived from their urban, demographic, and structural characteristics (Typ and Typ2 columns). The layer's attribute table also includes calculations of the component indicators (VL, PD, UI), which were used to carry out classification by cluster analysis (Cluster column).The “zones” layer shows four urban and peri-urban zones resulting from the combination of certain types of localities.Both layers can be opened in any GIS software (e.g. QGIS, SAGA GIS).</p

Two .exe file with results of in vitro maturation of activin A m-KO oocytes from InhbaKO/LoxP Zp3-Cre females and control oocytes from InhbaLoxP/LoxP females, including: File 2 with the number and percentage of mature MII stage oocytes (MII), oocytes after germinal vesicle breakdown (GVBD) and in the germinal vesicle (GV) stage, and degenerated oocytes, after 16 h of in vitro maturation;File 3 with the number and percentage of normal and abnormal meiotic spindles in oocytes after in vitro maturation.File 4 with data of morphokinetics parameters from time-lapse imaging of activin A m-KO, mz-KO, and control embryos.File 5 with the number and percentage of cell lineages cells of m-KO, mz-KO, and control blastocysts.File 6 with results of mitochondrial activity in m-KO and control MII oocytes, based on the green to red ratio of JC-1 staining. In each experiment, the mean fluorescence intensity of oocytes was normalized to that of control oocytes, which were stained and imaged simultaneously.File 7 with the ddPCR results of the number of Inhba transcripts in wild-type mouse GV, MII oocytes, COCs, and zygotes.Briefly about the project and data acquisition methods:In our project, we aimed to verify whether the lack of a phenotype in Inhba zygotic knockout embryos may be masked by the presence of maternal protein deposited in the oocyte during oogenesis. To this end, we carried out a conditional Inhba knockout in oocytes using Zp3-Cre/LoxP strategy, and received embryos with maternal knockout (m-KO), maternal and zygotic knockout (mz-KO). As a control, we used InhbaLoxP/LoxP embryos with a floxed but functional Inhba gene.The lack of activin A protein in Inhba mz-KO embryos was proved in the ELISA assay of the culture medium from mouse embryonic fibroblasts (MEFs) derived from Inhba mz-KO, Inhba m-KO and wild-type foetuses (File 1). To determine whether maternal activin A depletion affects oocyte in vitro maturation (IVM), we isolated fully grown germinal vesicle (GV) stage m-KO and control oocytes (from InhbaLoxP/LoxP females). After 16 hours of IVM, we calculated the number and percentages of the mature MII stage oocytes (MII), immature oocytes: after germinal vesicle breakdown (GVBD) and in the GV stage, and degenerated oocytes (File 2). We then used chromatin and β-tubulin staining to assess the potential effects of maternal activin A depletion on microtubule organization, spindle poles structure, and chromosome alignment. To visualize all sides, the meiotic spindle structure was assessed based on confocal Z-stack projections (File 3).To compare the phenotype of m-KO and mz-KO embryos with stage-matched control embryos, we analyzed the morphokinetics parameters by recording the progress of their development from the zygote to the blastocyst stage using time-lapse microscopy (File 4). The received blastocysts were immunostained to detect the presence of SOX2, SOX17, and CDX2, markers of epiblast (EPI), primitive endoderm (PE), and trophectoderm (TE), respectively. Then, using Imaris software, we counted the number and percentage of cells contributing to the cell lineages (EPI, PE, and TE) of m-KO, mz-KO, and control blastocysts (File 5).Next, we compared the mitochondrial activity in m-KO and control oocytes based on JC-1 staining. Mitochondrial membrane potential was determined as the ratio of red to green fluorescence intensity, calculated from the sum of signal intensities across all Z-stack layers. In each experiment, the mean fluorescence intensity of oocytes was normalized to that of control oocytes, which were stained and imaged simultaneously (File 6).Next, we used ddPCR analysis to study the Inhba mRNA levels in wild-type mouse GV, MII oocytes, cumulus-oocyte complex (COCs), and zygotes. The number of Inhba transcripts in a single ESC, oocyte, or embryo was calculated as follows: copy number/µl× dilution factor ×200 µl)/(number of ESCs or oocytes or embryos) (File 7).</p
Coprecipitation as a one-step Se separation for determination of isotope ratios completed with revised uncertainty evaluation
No full textSelected geological and biological reference materials were analyzed. These include the United States Geological Survey Reference Materials SGR-1 (oil shale, Green River Formation), SCo-1 (cody shale), MAG-1 (marine mud), European Reference Materials BC210a (selenized wheat flour), and selenium-enriched yeast-certified reference material SELM-1.These SRMs were analyzed: NIST SRM 3149 with the addition of a matrix, artificial seawater, and NASS-4 standard seawater spiked with NIST SRM 3149, SELM-1 and BC210a. In addition, the following geological standards were analyzed: SGR-1, SCo-1 and MAG-1.Selenium isotope ratios were measured at the Biological and Chemical Research Centre of the University of Warsaw using the Plasma 3 multicollector ICP mass spectrometer with 16 Faraday cups (Nu Instruments, Wrexham, U.K.). Three isotopes (77Se, 78Se, and 82Se) were chosen for isotope ratio measurements. Three of the Faraday collectors, H8 (82Se), Ax (78Se) and L2 (77Se), were set to register the signals and mass separation of 0.5 atomic mass unit was applied. All data sets reported in this files were collected between April and July 2023.The HGX-200 advanced membrane hydride generation system was applied for sample introduction to MC instrument. The instrument was running in dry plasma mode. The Time-Resolved Analysis (TRA) mode was used for gathering experimental data.The selenium isotope ratios were determined using the SSB method by sequential measurements of the standard-sample-standard. Such external calibration with NIST SRM 3149 provides the delta value. The results are expressed as δ.The sensitivity we achieved was >1 V 78Se per 100 μg/L. All samples were diluted to total Se content around 100 μg/L, except for the NASS-4 sample which was spiked at level 50 μg/L.</p

Rapid photoinduced self-healing, controllable drug release, skin adhesion ability, and mechanical stability of hydrogels incorporating linker-modified gold nanoparticles and nanogels
No full textThis dataset comes from a study exploring how to improve thermoresponsive poly(N-isopropylacrylamide) (pNIPAm) hydrogels for use in biomedical applications like drug delivery. To boost their performance, we added a custom-made cross-linker derived from natural amino acids called N,N′-bis(acryloyl)cystine (BISS), gold nanoparticles (GNPs) that bond through gold–sulfur interactions, and small nanogels made from the same pNIPAm-BISS material. These additions helped the hydrogels become stronger, heal themselves faster after damage, stick better to skin, and release drugs more effectively. We observed that the mechanical strength improved by about 65%, and the gels could stretch 25% more. Using a near-infrared (NIR) laser (800 nm, 0.75 W), the gels healed up to 85% in just 2 minutes. Drug release was also much better, reaching 0.08 mg/mL—almost double compared to unmodified gels. The data includes results from mechanical tests, drug release experiments, healing tests with NIR light, and temperature response studies. Altogether, these materials show good promise for smart biomedical systems that respond to light and heat.</p
Theoretical uncertainties for primordial black holes from cosmological phase transitions
No full textData used to plot the figures presented in the paper "Theoretical uncertainties for primordial black holes from cosmological phase transitions", arXiv:2506.15496.The files contain data for Figure 1 in the paper. Uploaded files are four .csv files corresponding to four subplots of Figure 1. The naming convention of .csv files follows the examples:SU2_1 --> SU(2)cSM model, I(Tp) = 1,SU2_34 --> SU(2)cSM model, I(Tp) = 34,i.e., we first denote the gauge group of the dark sector, and then the value of I(Tp) parameter for the percolation criterion. Each file contains data in three columns, with self-explanatory headers.Note that the data here are "raw," and to recreate the plots visible in the article, one should use interpolation and a median filter for the relevant regions of the parameter space.</p
