description: We present an initial study of one of the first ALMA Band 3 observations of the Sun with the aim to characterise the diagnostic potential of brightness temperatures measured with ALMA on the Sun. The observation covers 48min at a cadence of 2s targeting a Quiet Sun region at disk-centre. Corresponding time series of brightness temperature maps are constructed with the first version of the Solar ALMA Pipeline (SoAP) and compared to simultaneous SDO observations. The angular resolution of the observations is set by the synthesized beam (1.4x2.1as). The ALMA maps exhibit network patches, internetwork regions and also elongated thin features that are connected to large-scale magnetic loops as confirmed by a comparison with SDO maps. The ALMA Band 3 maps correlate best with the SDO/AIA 171, 131 and 304 channels in that they exhibit network features and, although very weak in the ALMA maps, imprints of large-scale loops. A group of compact magnetic loops is very clearly visible in ALMA Band 3. The brightness temperatures in the loop tops reach values of about 8000-9000K and in extreme moments up to 10 000K. ALMA Band 3 interferometric observations from early observing cycles already reveal temperature differences in the solar chromosphere. The weak imprint of magnetic loops and the correlation with the 171, 131, and 304 SDO channels suggests though that the radiation mapped in ALMA Band 3 might have contributions from a larger range of atmospheric heights than previously assumed but the exact formation height of Band 3 needs to be investigated in more detail. The absolute brightness temperature scale as set by Total Power measurements remains less certain and must be improved in the future. Despite these complications and the limited angular resolution, ALMA Band 3 observations have large potential for quantitative studies of the small-scale structure and dynamics of the solar chromosphere.

description: Menstruation is the monthly shedding of the endometrium lining of a woman's uterus. The average age when girls start menstruating is around the age of 12 years (menarche), and the cycle continues until they attain menopause (about the age of 51). Medical research and analysis in this field reveal that most women have to go through a painful cycle of abdominal cramps along with sanitary pad rashes, while painkillers or endurance ability are their go-to solution. Heat pads or hot water bags also help in pain reduction. Currently, the concept of period pants revolves around pad-free and hassle-free periods for women, whereas most women still prefer sanitary pads during their period cycle. MIMA aims at the development of IoT integrated smart, functional intimate wear for women that would help women comfort during menstruation by catering to issues of menstrual cramps, rashes, leakage and stains, malodor, etc. The proposed methodology has been implemented by referring to the online survey conducted from Indian women (17-58 years old). MIMA can provide comfort during the menstruation cycle with IoT integrated Heat-Pad and functional alterations in the garment for a rash-free, anti-odor, and leak-proof period.

Caustic Formation in Tachyon Effective Field Theories

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Certain configurations of D-branes, for example wrong dimensional branes or the brane-antibrane system, are unstable to decay. This instability is described by the appearance of a tachyonic mode in the spectrum of open strings ending on the brane(s). The decay of these unstable systems is described by the rolling of the tachyon field from the unstable maximum to the minimum of its potential. We analytically study the dynamics of the inhomogeneous tachyon field as it rolls towards the true vacuum of the theory in the context of several different tachyon effective actions. We find that the vacuum dynamics of these theories is remarkably similar and in particular we show that in all cases the tachyon field forms caustics where second and higher derivatives of the field blow up. The formation of caustics signals a pathology in the evolution since each of the effective actions considered is not reliable in the vicinity of a caustic. We speculate that the formation of caustics is an artifact of truncating the tachyon action, which should contain all orders of derivatives acting on the field, to a finite number of derivatives. Finally, we consider inhomogeneous solutions in p-adic string theory, a toy model of the bosonic tachyon which contains derivatives of all orders acting on the field. For a large class of initial conditions we conclusively show that the evolution is well behaved in this case. It is unclear if these caustics are a genuine prediction of string theory or not.

Added comments concerning the relationship between p-adic string theory and tachyon matter. Added second example of inhomogeneous evolution in p-adic string theory.

description: This deliverable examines national climate service activities in Denmark, Germany and Serbia, highlighting the critical role of public and private sectors. National Meteorological and Hydrological Services are identified as key public providers, complemented by academic projectbased contributions and private sector expertise in consultancy and risk assessments. Challenges are also discussed, including lack of coherence among providers, absence of standardisation, and transparency issues which undermine climate service trust and use. Climate services are seeing increased use cities because of climate risk studies and adaptation planning, especially in cities with mandatory climate action frameworks. Standardisation and improved accessibility are deemed necessary to address quality concerns. Climate service use in the energy sector is also explored, with a focus on the market for wildfire-related climate services. The findings illustrate the need for public-private collaboration and capacity-building to enhance resilience and adaptation, addressing both immediate and long-term risks. Similarly, the financial sector integrates climate services to manage climate-related risks and meet regulatory requirements, although the lack of standardisation and tailored solutions remain an issue. Finally, data marketplaces are emerging as a way for improving the accessibility of climate information across sectors, strengthening climate risk management.

description: Dual band dual mode chebychev micro strip band pass filter designs are introduced for first time in this paper. The proposed filter designs are based on the use of dual mode square slotted patch micro strip resonator. These filter structures are fractally generated using Sierpinski fractal curve geometry applied to the conventional square micro strip patch from 1st to 2nd iteration levels where the first band designed at fundamental frequencies (5.475, 5.45 and 5.4) GHz for each iteration while the second band( 8.925, 9.15, 9.05) GHz for each iteration. These filters have been designed using a substrate with a dielectric constant of 10.8 and thickness of 1.27mm. The performance of filter structures, based on resonators has been evaluated using a full-wave based electromagnetic simulator Sonnet software package. Performance simulation results show that these filter structures are compact in addition to good frequency responses and narrow bands gained.

description: We consider coupled nonlinear Schrodinger equations (CNLSE) which govern the propagation of nonlinear waves in bimodal optical fibers. The nonlinear transform of a dual-frequency signal is used to generate an ultra-short-pulse train. To predict the energy and width of pulses in the train, we derive three new types of travelling periodic-wave solutions, using the Hirota bilinear method. We also show that all the previously reported periodic wave solutions of CNLSE can be derived in a systematic way, using the Hirota method.

description: We describe and analyze HST/STIS observations of the G2 V star alpha Centauri A (alpha Cen A, HD 128620), a star similar to the Sun. The high resolution echelle spectra obtained with the E140H and E230H gratings cover the complete spectral range 1133-3150 Angstrom with a resolution of 2.6 km/s, an absolute flux calibration accurate to +/-5%, and an absolute wavelength accuracy of 0.6-1.3 km/s. We present here a study of the E140H spectrum covering the 1140-1670 Angstrom spectral range, which includes 671 emission lines representing 37 different ions and the molecules CO and H_2. For alpha Cen A and the quiet and active Sun, we intercompare the redshifts, nonthermal line widths, and parameters of two Gaussian representations of transition region lines (e.g., Si IV, C IV), infer the electron density from the O IV intersystem lines, and compare their differential emission measure distributions. One purpose of this study is to compare the alpha Cen A and solar UV spectra to determine how the atmosphere and heating processes in alpha Cen A differ from the Sun as a result of the small differences in gravity, age, and chemical composition of the two stars. A second purpose is to provide an excellent high resolution UV spectrum of a solar-like star that can serve as a proxy for the Sun observed as a point source when comparing other stars to the Sun.

description: With emerging usage of positioned devices such as drones, cell phones or IoT, the amount of data that can be collected expands drastically. At any given time, there is usually at least one nearby device that has positioning capabilities. Smart phones, smart TVs, personal computers, or even cars contain localization features. These vast amounts of data require a lot of effort in analysis and understanding in order to be properly utilized, which is especially true for the field of agriculture, where proper analysis can yield tremendous improvements in terms of production. Current computer technologies offer plenty options for such analysis. However, not every agricultural subject has access to a mainframe with performance in petaflops to perform complicated analyses of such big data in a timely manner. The defined design patterns for creation of data offers potential for speeding up the analysis of ADS on personal computers. This article describes known and used creational patterns and compares their benefits regarding ADS and offers possible usage and improvements.

description: Ensuring the generation renewal in the agriculture is crucial. There are policy incentives to attract young people, but the motivation to enter the sector depend on many factors and there are also barriers. The aim of the paper is to assess the motivation and barriers of the young farmers, newcomers to the agrarian sector in the Czech Republic and to draft the conclusions for policy and incentives creation. Based on answers of 510 young farmers, the main motive to enter was the wish to continue with farming on the farm of the parents or other relatives and to work in nature and with animals. The hardest was to purchase the agricultural land, administrative burden and ensuring the finances for the development and for start-up. Hence, to facilitate the start-up it is useful to support the land purchase and provide investment subsidies. The research was financed from internal research project 1113/2018.

description: Cosmological (LCDM) TreeSPH simulations of galaxy clusters have been performed, invoking star-formation, chemical evolution with non-instantaneous recycling, metal dependent radiative cooling, strong star-burst and/or AGN driven super-winds, effects of a meta-galactic UV field and thermal conduction. Results for two clusters, one Virgo-like (T~3 keV) and one (sub) Coma-like (T~6 keV), are presented. At z=0, the stellar contents of both clusters consist of a central dominant (cD) galaxy surrounded by galaxies and intracluster (IC) stars. The IC stars are found to contribute 20-40% of the total cluster B-band light and to form at a mean redshift z_f~3, on average about 0.5 Gyr prior to the stars in galaxies. UBVRIJHK surface brightness profiles of the IC star populations are presented; the profile of the larger cluster matches the observed V-band profile of the cD in Abell 1413 (T~8 keV). The IC stellar populations have B-R=1.4-1.5, comparable to larger E galaxies. The mean [Fe/H]~0.0 in the central part of the cluster (r~100 kpc) decreasing to about -0.3 at r_vir. The IC stars are alpha-element enhanced, with a weak trend of [O/Fe] increasing with r, and an overall [O/Fe]~0.4 dex. The IC stars are kinematically colder than the galaxies: The velocity dispersions of the IC stars are at r~100-500 kpc only about half of those of the galaxies increasing to about 70% at r=1-2 Mpc. The projected velocity dispersion in the Virgo-like cluster at R>~50 kpc is 300-600 km/s depending on orientation and R. Rotation is dynamically insignificant for the IC stars. The velocity distributions of IC stars and galaxies are in one cluster highly radially anisotropic, in the other close to isotropic.

description: Here we present the synthesis of complementary (pseudo) nucleobase appended Supramolecular Self-associating Amphiphilic (SSA) salts and, establish the potential for this molecular construct to produce a new class of DNA inspired synthetic structures/materials. The anionic component of this class of amphiphile contains multiple hydrogen bond donating and accepting functionalities, meaning that these systems can access multiple self-associative hydrogen-bonding modes simultaneously. Herein, we characterise the self-associative properties of these DNA inspired amphiphiles in the solid state, solution state and gas phase. Finally, we investigate the potential of these amphiphilic salts to act as antimicrobial agents against model Gram-positive (methicillin-resistant Staphylococcus aureus – MRSA) and Gram-negative (Escherichia coli – E. coli) bacteria.

description: Diaminomalenonitrile-linked naphthalimide 1 has been designed and synthesised. It shows selective sensing of F−, CN−, Cu2+ and Hg2+ under different experimental conditions. While compound 1 in CH3CN exhibits colour change from yellow to greenish blue or green in the presence of F−, AcO−, CN− and H2PO4−, it shows a colour change from yellow to light green selectively in presence of CN− in aqueous CH3CN. The selectivity of 1 for F− in pure CH3CN is achieved by using Ca2+ ion as chelating agent. Besides anion sensing, the probe exhibits different colour attributes towards Hg2+ and Cu2+ ions in aqueous CH3CN. While the yellowish solution of 1 is discharged to almost colourless in presence of Cu2+ ions, a light red colour is observed in the presence of Hg2+ ions. The interaction study has been performed by NMR, UV-vis, fluorescence and mass spectroscopic techniques. A theoretical study has been invoked to understand the deprotonation of 1 that occurs in presence of basic anions.

description: The paper investigates the effects of sector-wide and country-specific determinants on profitability of the dairy industry in the Czech Republic, Slovakia, Poland and Hungary over the period of years 2006- 2014. Using an econometric approach, a hypothesis about the impact of various drivers of firm performance on both sector and country level was tested. The findings confirm that these factors have a significant impact on the dairy firms’ performance in the V4 countries. It was found out that foreign competition measured by the import penetration ratio had significant negative impact on dairy firm performance. The positive development of GDP and market concentration affected profitability positively. The results could help in designing common agricultural and industrial policy in the European Union as well as in managing the mutual trade of milk products in V4 countries.

description: Transverse momentum dependent parton distribution functions (TMDPDFs) provide a unique probe of the three-dimensional spin structure of hadrons. We construct spin-dependent quasi-TMDPDFs that are amenable to lattice QCD calculations and that can be used to determine spin-dependent TMDPDFs. We calculate the short-distance coefficients connecting spin-dependent TMDPDFs and quasi-TMDPDFs at one-loop order. We find that the helicity and transversity distributions have the same coefficient as the unpolarized TMDPDF. We also argue that the same is true for pretzelosity and that this spin universality of the matching will hold to all orders in $α_s$. Thus, it is possible to calculate ratios of these distributions as a function of longitudinal momentum and transverse position utilizing simpler Wilson line paths than have previously been considered.

description: Combining samples for genetic association is standard practice in human genetic analysis of complex traits, but is rarely undertaken in rodent genetics. Here, using 23 phenotypes and genotypes from two independent laboratories, we obtained a sample size of 3,076 commercially available outbred mice and identified 70 loci, more than double the number of loci identified in the component studies. Fine-mapping in the combined sample reduced the number of likely causal variants, with a median reduction in set size of 51%, and indicated novel gene associations, including Pnpo, Ttll6 and GM11545 with bone mineral density, and Psmb9 with weight. However replication at a nominal threshold of 0.05 between the two component studies was low, with less than a third of loci identified in one study replicated in the second. In addition to overestimates in the effect size in the discovery sample (Winner's Curse), we also found that heterogeneity between studies explained the poor replication, but the contribution of these two factors varied among traits. Leveraging these observations we integrated information about replication rates, study-specific heterogeneity, and Winner's Curse corrected estimates of power to assign variants to one of four confidence levels. Our approach addresses concerns about reproducibility, and demonstrates how to obtain robust results from mapping complex traits in any genome-wide association study.

description: Selective anion sensors can be used in the colourimetric detection of certain anions. In the present study, two new 1,2,4-triazole derivatives containing thiol group and azo moiety 3a (nitrile derivative) and 3b (methoxy derivative) were synthesised by condensation of 4-(4-amino-5-mercapto-4 H-1,2,4-triazol-3-yl)phenol (1) and aromatic aldehydes containing azo groups 2a and 2b under acidic conditions. The nitrile derivative 3a acted as a selective naked-eye sensor for acetate anions in a mixture of dimethyl sulphoxide and water (9:1 by volume). It interacted with the acetate anions in a 1:2 stoichiometry with strong positive cooperativity and an overall association constant (β12) exceeding 2 × 108 M−2. The detection limit of 3a towards the acetate anion was found to be 0.66 × 10−5 M. The DFT studies showed that both 3a and 3b were similar in their electronic properties, but the internal charge transfer for 3a was responsible for the positive response to acetate anions.

Possible observational signatures of SMBHBs in their Fe K$α$ line profiles

description: Here we study the potential observational signatures of supermassive black hole binaries (SMBHBs) in the Fe K$α$ line profiles emitted from the accretion disks around their components. We simulated the Fe K$α$ line emission from the relativistic accretion disks using ray tracing method in Kerr metric. The obtained profiles from the SMBHBs are then compared with those in the case of the single supermassive black holes (SMBHs). We considered two models of the SMBHBs: a model when the secondary SMBH is embedded in the accretion disk around the primary, causing an empty gap in the disk, and a model with clearly separated components, where the accretion disks around both primary and secondary give a significant contribution to the composite Fe K$α$ line emission of a such SMBHB. The obtained results showed that both models of SMBHBs can leave imprints in the form of ripples in the cores of the emitted Fe K$α$ line profiles, which may look like an absorption component in the line profile. However, in the case of the composite line profiles emitted from two accretion disks, these ripples could have much higher amplitudes and strongly depend on orbital phase of the system, while for those emitted from a disk with an empty gap, the corresponding ripples mostly have lower amplitudes and do not vary significantly with orbital phase. The present day X-ray telescopes are not able to detect such signatures in the observed X-ray spectra of SMBHBs. However this will be possible with the next generation of X-ray observatories, which will also enable application of such effects as a tool for studying the properties of these objects.

Chaotic Scattering with Localized Losses: S-Matrix Zeros and Reflection Time Difference for Systems with Broken Time Reversal Invariance

description: Motivated by recent studies of the phenomenon of Coherent Perfect Absorption, we develop the random matrix theory framework for understanding statistics of the zeros of the (subunitary) scattering matrices in the complex energy plane, as well as of the recently introduced Refection Time Difference (RTD). The latter plays the same role for S-matrix zeros as the Wigner time delay does for its poles. For systems with broken time-reversal invariance, we derive the n -point correlation functions of the zeros in a closed determinantal form, and study various asymptotics and special cases of the associated kernel. The time-correlation function of the RTD is then evaluated and compared with numerical simulations. This allows to identify a cubic tail in the distribution of RTD, which we conjecture to be a superuniversal characteristic valid for all symmetry classes. We also discuss two methods for possible extraction of S-matrix zeroes from scattering data by harmonic inversion.

description: The high dimensionality of hyperspectral images (HSI) that contains more than hundred bands (images) for the same region called Ground Truth Map, often imposes a heavy computational burden for image processing and complicates the learning process. In fact, the removal of irrelevant, noisy and redundant bands helps increase the classification accuracy. Band selection filter based on "Mutual Information" is a common technique for dimensionality reduction. In this paper, a categorization of dimensionality reduction methods according to the evaluation process is presented. Moreover, a new filter approach based on three variables mutual information is developed in order to measure band correlation for classification, it considers not only bands relevance but also bands interaction. The proposed approach is compared to a reproduced filter algorithm based on mutual information. Experimental results on HSI AVIRIS 92AV3C have shown that the proposed approach is very competitive, effective and outperforms the reproduced filter strategy performance. Keywords - Hyperspectral images, Classification, band Selection, Three variables Mutual Information, information gain.

description: Reaction of KOH with 2,4-Dinitrobenzoic acid (L1H) in the presence of acetonitrile-water mixture yielded product [K(μ5-L1).H2O]n resulted in a dramatic structural transformation into 3D polymeric complex. The observed structural transformation is arising from the coordination through carboxylate as well as both nitro groups. This polymeric complex has been solved in triclinic centrosymmetric space group (Pī) and characterised by elemental analysis, FT-IR spectroscopy, powder X-ray diffraction analysis and single-crystal diffraction analysis. This complex attains high thermal stability up to 423°C. During investigation of various intermolecular interactions, both X-ray diffraction and Hirshfeld surface analysis give comparable results. DFT calculations and X-ray studies show an excellent agreement and resulting molecular geometry depends on the choice of functional, theoretical calculations which were carried out with the B3LYP level of theory using 6–31 G basis set. The complex {[K(L1)].H2O}n is synthesised by dramatic structural transformation into 3D polymer additionally by nitro group coordination. This 3D polymeric complex attains high thermal stability up to 423°C. During investigation of various intermolecular interactions, both X-ray diffraction and Hirshfeld surface analysis give comparable results.
