Investigating the Heartbeat-evoked cortical responses through parametric Time-Varying Information Measures

Recent studies showed that the information coming from the heart is constantly processed by the brain. One index to study this process is the heartbeat-evoked potential (HEP), represented by an event-related potential component related to the cortical processing of the heartbeat. In this study we propose an approach to investigate the heartbeat-evoked EEG responses, based on quantifying the changes induced by the heartbeat on the predictability of the brain dynamics. The regularity of EEG signals is assessed through the Information Storage (IS) computed with a time-varying approach able to derive the temporal profile of the measure for each time point. Results show a modulation in the regularity of EEG signals induced by the heartbeat that can be revealed with the proposed approach in a group of healthy subjects during a resting state.

Constraints on 3.55 keV line emission from stacked observations of dwarf spheroidal galaxies

Several recent works have reported the detection of an unidentified x-ray line at 3.55 keV, which could possibly be attributed to the decay of dark matter (DM) particles in the halos of galaxy clusters and in the M31 galaxy. We analyze all publicly available XMM-Newton satellite data of dwarf spheroidal galaxies to test the possible DM origin of the line. Dwarf spheroidal galaxies have high mass-to-light ratios, and their interstellar medium is not a source of diffuse x-ray emission; thus, they are expected to provide the cleanest DM decay line signal. Our analysis shows no evidence for the presence of the line in the stacked spectra of the dwarf galaxies. It excludes the sterile neutrino DM decay origin of the 3.5 keV line reported by Bulbul et al. (2014) at the level of $4.1\ensuremath{\sigma}$ under standard assumptions about the Galactic DM column density in the direction of selected dwarf galaxies and at the level of $3.2\ensuremath{\sigma}$ assuming minimal Galactic DM column density. Our analysis is still consistent with the estimate of sterile neutrino DM parameters by Boyarsky et al. (2014) because of its larger uncertainty. However, the central value of their estimate of the mixing angle is inconsistent with our dwarf spheroidals data at the $3.4\ensuremath{\sigma}$ ($2.5\ensuremath{\sigma}$) level assuming the mean (minimal) Galactic DM column density. As a byproduct of our analysis, we provide updated upper limits to the mixing angle of sterile neutrino DM in the mass range between 2 and 20 keV.
A magneto-optical trap created by the 2nd-order external cavity diode lasers.

In this article, we report on a magneto-optical trap (MOT) created by the 2nd-order external cavity diode lasers (ECDLs). The lasers were characterized. We have observed the non-continuous changes of the wavelength as a function of the laser diode current. This study is beneficial for achieving tunable atom-atom interactions, quantum tunneling, precision measurement, ultracold plasma, as well as quantum computing.
Exploring alignment of assumptions in plural leadership: A case study of managers’ implicit leadership theories in the danish public sector

Several researchers have observed that growing attention has been given to the concept of plural leadership in the past couple of decades. However, the role of the manager is largely overlooked in the plural leadership literature. In this study, I draw on the concept of implicit leadership theories to explore how managers’ assumptions about leadership might influence organisations’ ability to realise plural leadership. Based on participant observation and interview data, I identify three basic managerial assumptions about leadership that align poorly with the principles of plural leadership: (1) management positions entail ultimate accountability, (2) disagreement is definitively bad, and (3) resistance is exclusively caused by faulty processes. I argue that these assumptions constitute an obstacle to the practical realisation of plural leadership and consequently that interventions targeting managers’ implicit leadership theories might be effective in developing plural leadership beyond rhetorical changes.
The Use of a Time-Changing Magnetic Field to Increase Soybean (Glycine max) Growth and Productivity

This study aimed to accelerate the growth and increase the productivity of soybean plants by providing treatment using a magnetic field at the time of seed germination. The research sample was soybean seeds of the Grobogan variety obtained from Center for Research on Various Tubers and Nuts. The magnetic field used in the treatment is in the direction of the magnetic flux density, which changes with time, and the change frequency is 100 times per second. The treatments were given with magnetic flux density from 0.0 mT to 0.5 mT for 20 minutes per day and repeated for five days. Treatment with a 0.1 mT magnetic field resulted in optimum values of germination emergence time, stem growth, chlorophyll content, early flowering time, weight per 10 seeds, and productivity. Treatment with a 0.5 mT magnetic flux density had a negative or no effect on the growth and productivity of soybean plants. Treatment using a magnetic field of 0.1-0.4 mT positively affected soybean growth and productivity, while 0.5 mT did not affect or negatively affect. The treatment of the magnetic field can have positive and negative effects depending on the magnetic flux density used.
A DEEP CHANDRA VIEW OF THE NGC 404 CENTRAL ENGINE

We present the results of a 100 ks Chandra observation of the NGC 404 nuclear region. The long exposure and excellent spatial resolution of Chandra have enabled us to critically examine the nuclear environment of NGC 404, which is known to host a nuclear star cluster and potentially an intermediate-mass black hole (IMBH; on the order of a few times 105 M☉). We find two distinct X-ray sources: a hard, central point source coincident with the optical and radio centers of the galaxy, and a soft extended region that is coincident with areas of high Hα emission and likely recent star formation. When we fit the 0.3–8 keV spectra of each region separately, we find the hard nuclear point source to be dominated by a power law (Γ = 1.88), while the soft off-nuclear region is best fit by a thermal plasma model (kT = 0.67 keV). We therefore find evidence for both a power-law component and hot gas in the nuclear region of NGC 404. We estimate the 2–10 keV luminosity to be 1.3+0.8−0.5 × 1037 erg s−1. A low level of diffuse X-ray emission was detected out to ∼15″ (∼0.2 kpc) from the nucleus. We compare our results to the observed relationships between power-law photon index and Eddington ratio for both X-ray binaries and low-luminosity active galaxies and find NGC 404 to be consistent with other low-luminosity active galaxies. We therefore favor the conclusion that NGC 404 harbors an IMBH accreting at a very low level.
THE NATURE OF Hα-SELECTED GALAXIES AT z > 2. II. CLUMPY GALAXIES AND COMPACT STAR-FORMING GALAXIES

We present the morphological properties of Hα-selected galaxies at z > 2 in SXDF-UDS-CANDELS field. With high-resolution optical/near-infrared images obtained by the Hubble Space Telescope, we identify giant clumps within the Hα emitters (HAEs). We find that at least 41% of our sample shows clumpy structures in the underlying disks. The color gradient of clumps is commonly seen in the sense that the clumps near the galactic center tend to be redder than those in the outer regions. The mid-infrared detection in galaxies with red clumps and the spatial distribution of Hα emission suggest that dusty star-formation activity is probably occurring in the nuclear red clumps. A gas supply to a bulge component through clump migration is one of the most potent physical processes for producing such dusty star-forming clumps and forming massive bulges in local early-type galaxies. They would become large quiescent galaxies at later times just by consumption or blowout of remaining gas. Also, while most of the HAEs have extended disks, we observe two massive, compact HAEs whose stellar surface densities are significantly higher. They are likely to be the direct progenitors of massive, compact quiescent galaxies at z = 1.5–2.0. Two evolutionary paths to massive quiescent galaxies are devised to account for both the size growth of quiescent galaxies and their increased number density from z ∼ 2 to z = 0.
Exact Results in Discretized Gauge Theories

We apply the localization technique to topologically twisted N=(2,2) supersymmetric gauge theory on a discretized Riemann surface (the generalized Sugino model). We exactly evaluate the partition function and the vacuum expectation value (vev) of a specific Q-closed operator. We show that both the partition function and the vev of the operator depend only on the Euler characteristic and the area of the discretized Riemann surface and are independent of the detail of the discretization. This localization technique may not only simplify numerical analysis of the supersymmetric lattice models but also connect the well-defined equivariant localization to the empirical supersymmetric localization.
Overcharging and charge reversal in the electrical double layer near the point of zero charge

The ionic adsorption around a weakly charged spherical colloid, immersed in size-asymmetric 1:1 and 2:2 salts, is studied. We use the primitive model of an electrolyte to perform Monte Carlo simulations as well as theoretical calculations by means of the hypernetted chain/mean spherical approximation (HNC/MSA) and the unequal-radius modified Gouy-Chapman (URMGC) integral equations. Structural quantities such as the radial distribution functions, the integrated charge, and the mean electrostatic potential are reported. Our Monte Carlo "experiments" evidence that near the point of zero charge the smallest ionic species is preferentially adsorbed onto the macroparticle, independently of the sign of the charge carried by this tiniest electrolytic component, giving rise to the appearance of the phenomena of charge reversal and overcharging. Accordingly, charge reversal is observed when the macroion is slightly charged and the coions are larger than the counterions. In the opposite situation, i.e. if the counterions are larger than the coions, overcharging occurs. In other words, in this paper we present the first simulational data on overcharging, showing that this novel effect surges close to the point of zero charge as a consequence of the ionic size asymmetry. Further, it is seen that the inclusion of hard-core correlations in HNC/MSA leads to spatial regions near the macroion's surface in which the integrated charge and/or the mean electrostatic potential can decrease when the colloidal charge is augmented and vice versa. These observations aware about the interpretation of electrophoretic mobility measurements using the standard Poisson-Boltzmann approximation beyond its validity region.
Type Ib Supernova Master OT J120451.50+265946.6: Radio-emitting Shock with Inhomogeneities Crossing through a Dense Shell

We present radio observations of Type Ib supernova (SN) Master OT J120451.50+265946.6. Our low-frequency Giant Metrewave Radio Telescope (GMRT) data, taken when the SN was in the optically thick phase for observed frequencies, reveal inhomogeneities in the structure of the radio-emitting region. The high-frequency Karl G. Jansky Very Large Array data indicate that the shock is crossing through a dense shell between ∼47 and ∼87 days. The data ≥100 days onward are reasonably well fit with the inhomogeneous synchrotron self-absorption model. Our model predicts that the inhomogeneities should smooth out at late times. Low-frequency GMRT observations at late epochs will test this prediction. Our findings suggest the importance of obtaining well-sampled wide-band radio data in order to understand the intricate nature of the radio emission from young supernovae.
Ab initio calculations of permanent dipole moments and dipole polarizabilities of alkaline-earth monofluorides

The ground-state permanent dipole moments (PDMs) and molecular dipole polarizabilities (DPs) of open-shell alkaline-earth monofluorides, and atomic DPs of alkaline-earth- and fluorine atoms are reported at the Kramers-restricted configuration interaction level of theory limited to single and double excitations (KRCISD), using the finite-field approach. Sufficiently large basis sets such as quadrupole-zeta (QZ) and augmented-QZ basis sets together with the generalized active space technique is employed to carry out the field-dependent energy calculations at the KRCISD level. The PDMs and the components of DPs are extracted from the linear- and quadratic fit of energies against perturbative electric field, respectively. Accuracy of the present calculations for the electronic properties is examined by comparison with the measurements and calculations where ever available.
GALAXY-SCALE GRAVITATIONAL LENS CANDIDATES FROM THE HYPER SUPRIME-CAM IMAGING SURVEY AND THE GALAXY AND MASS ASSEMBLY SPECTROSCOPIC SURVEY

We present a list of galaxy-scale lens candidates including a highly probable interacting galaxy-scale lens in the Hyper Suprime-Cam (HSC) imaging survey. We combine HSC imaging with the blended-spectra catalog from the Galaxy And Mass Assembly (GAMA) survey to identify lens candidates, and use lens mass modeling to confirm the candidates. There are 45 matches between the HSC S14A_0b imaging data release and the GAMA catalog. We separate lens and lensed arcs using color information, and exclude those candidates with small image separations (<1.″0, estimated with the lens/source redshifts from the GAMA survey) that are not easily resolved with ground-based imaging. After excluding these, we find 10 probable lens systems. There is one system with an interacting galaxy pair, HSC J084928+000949, that has a valid mass model. We predict the total mass enclosed by the Einstein radius of ∼0. ″72 (∼1.65 kpc) for this new expected lens system to be . Using the photometry in the grizy bands of the HSC survey and stellar population synthesis modeling with a Salpeter stellar initial mass function, we estimate the stellar mass within the Einstein radius to be . We thus find a dark matter mass fraction within the Einstein radius of . Further spectroscopy or high-resolution imaging would allow confirmation of the nature of these lens candidates. The particular system with the interacting galaxy pair, if confirmed, would provide an opportunity to study the interplay between dark matter and stars as galaxies build up through hierarchical mergers.
Adinkras, 0-branes, Holoraumy and the SUSY QFT/QM Correspondence

We propose the recently defined "Holoraumy Tensor" to play a critical role in defining a metric to establish a correspondence between 4D, -extended 0-brane-based valise supermultiplet representations and, correspondingly via "SUSY Holography," on the space of 1D, N-extended network-based adinkras. Using an analogy with the su(3) algebra, it is argued the 0-brane holoraumy tensors play the role of the "d-coefficients" and provide a newly established tool for investigating supersymmetric representation theory.
Degree distribution in quantum walks on complex networks

In this theoretical study, we analyze quantum walks on complex networks, which model network-based processes ranging from quantum computing to biology and even sociology. Specifically, we analytically relate the average long time probability distribution for the location of a unitary quantum walker to that of a corresponding classical walker. The distribution of the classical walker is proportional to the distribution of degrees, which measures the connectivity of the network nodes and underlies many methods for analyzing classical networks including website ranking. The quantum distribution becomes exactly equal to the classical distribution when the walk has zero energy and at higher energies the difference, the so-called quantumness, is bounded by the energy of the initial state. We give an example for which the quantumness equals a Renyi entropy of the normalized weighted degrees, guiding us to regimes for which the classical degree-dependent result is recovered and others for which quantum effects dominate.
Final state interactions and CP violation in B decays to three pseudoscalars

We study CP violation and final state interactions between pions and kaons in B+, B-, B0 and bar B0 decays into K pi pi. The weak transition amplitudes consist of two terms: the first part is derived in QCD factorization approach and the second one is a phenomenological long-distance charming penguin contribution. The final state K pi interactions in S- and P-waves are described by strange scalar and vector form factors, respectively. These are determined using a unitary coupled channel model together with chiral symmetry and asymptotic QCD constraints. The final state interactions are dominated by presence of the scalar K*0(1430) and the vector K*(892) resonances. We show that additional charming penguin amplitudes are needed to reproduce the latest experimental K pi effective mass and helicity angle distributions, branching fractions and asymmetries obtained by Belle and BaBar collaborations.
Effect of irrigation intervals, mineral and organic fertilization on productivity of henna (Lawsonia alba Lam) plants

A field experiments were carried out in Aswan governorate, Egypt, during the two successive seasons, 2019 and 2020, to evaluate the effects of irrigation intervals, organic fertilization and NPK at the recommended dose (NPK R ) on growth, yield and some chemical constituents of henna ( Lawsonia alba Lam) plants. The irrigation intervals were I 1 (every 7 day), I 2 (every 14 day) and I 3 (every 21 day), while fertilizer treatments were control (without), chemical fertilizer (recommend does of NPK R ), two levels of farmyard manure (15 and 25 m 3 / feddan −1 (feddan =4200 m 2 )) and two levels of compost (10 and 15 m 3 feddan −1 ). The results showed that, generally, by increasing irrigation intervals from one week to 3 weeks interval the growth characteristics, yield and chemical constituents, among all cuts, in both seasons were decreased. The highest values of these traits were observed when irrigating henna plants everyone I1, followed 2 weeks (I 2 ). Regarding NPK and organic fertilization treatments, all of them led an increase in the growth, yield and chemical constituents mostly. The best results when the addition of NPK R followed by compost at 15 m 3 feddan −1 . The combined effect between irrigation intervals, NPK and organic fertilization on henna ( Lawsonia alba Lam) plants was statistically significant. In most cases, irrigation of henna plants every one week (I) with fertilization of NPK at the recommend dose or with compost at 15 m 3 feddan −1 were the most effective treatments, mostly concerning growth, yield, as well as chemical constituents.
Non-invasive follow-up of Egyptian patients infected with Helicobacter pylori by quantification of H. pylori circulating antigen in serum using ELISA

Clinicians still wish to determine if H. pylori -infected patients have been cured after specific treatment. The present study aimed to evaluate the reliability of the H. pylori circulating antigen (HpCAg) test for noninvasive screening of H. pylori infection and assessment of cure after specific treatment. Sera of 134 symptomatic individuals (81 males & 53 females, aged 23-68 yr) were screened for HpCAg using ELISA. H. pylori infection was confirmed using a gold standard based on culture, rapid urease test, and histology testing. The detection rate of HpCAg was 69% among screened individuals. The gold standard confirmed H. pylori infection in 93% of individuals showing HpCAg in their sera. In addition, 31% of infected patients were excluded for their drug resistance. Eligible individuals received a standard triple therapy regimen including Lansoprazole, Clarithromycin, and Amoxicillin twice daily for 14 days. Six weeks later, the HpCAg testing was repeated to evaluate the treatment outcome. HpCAg was not detected in 78 % of treated individuals. Furthermore, the levels of HpCAg were significantly decreased (p < 0.001) in the sera of non-responders. In conclusion, the detection of HpCAg is a reliable non-invasive approach for screening and follow-up of H. pylori -infected individuals after treatment, especially in developing countries.
FAR-ULTRAVIOLET SPECTROSCOPY OF THE NOVA-LIKE VARIABLE KQ MONOCEROTIS: A NEW SW SEXTANTIS STAR?

New optical spectra obtained with the SMARTS 1.5 m telescope and archival International Ultraviolet Explorer (IUE) far-ultraviolet (FUV) spectra of the nova-like variable KQ Mon are discussed. The optical spectra reveal Balmer lines in absorption as well as He i absorption superposed on a blue continuum. The 2011 optical spectrum is similar to the KPNO 2.1 m IIDS spectrum we obtained 33 years earlier except that the Balmer and He i absorption is stronger in 2011. Far-ultraviolet IUE spectra reveal deep absorption lines due to C ii, Si iii, Si iv, C iv, and He ii, but no P Cygni profiles indicative of wind outflow. We present the results of the first synthetic spectral analysis of the IUE archival spectra of KQ Mon with realistic optically thick, steady-state, viscous accretion-disk models with vertical structure and high-gravity photosphere models. We find that the photosphere of the white dwarf (WD) contributes very little FUV flux to the spectrum and is overwhelmed by the accretion light of a steady disk. Disk models corresponding to a WD mass of ∼0.6 M☉, with an accretion rate of order 10−9 M☉ yr−1 and disk inclinations between 60° and 75°, yield distances from the normalization in the range of 144–165 pc. KQ Mon is discussed with respect to other nova-like variables. Its spectroscopic similarity to the FUV spectra of three definite SW Sex stars suggests that it is likely a member of the SW Sex class and lends support to the possibility that the WD is magnetic.
GAS ACCRETION IN THE M32 NUCLEUS: PAST AND PRESENT

Using adaptive optics assisted Gemini/NIFS data, I study the present and past gas accretion in the central 3″ of the M32 nucleus. From changes in the spectral slope and CO line depths near the center, I find evidence for unresolved dust emission resulting from black hole (BH) accretion. With a luminosity of ∼2 × 1038 erg s−1, this dust emission appears to be the most luminous tracer of current BH accretion, 2 orders of magnitude more luminous than previously detected X-ray emission. These observations suggest that using high-resolution infrared data to search for dust emission may be an effective way to detect other nearby, low-luminosity BHs, such as those in globular clusters. I also examine the fossil evidence of gas accretion contained in the kinematics of the stars in the nucleus. The higher order moments (h3 and h4) of the line-of-sight velocity distribution show patterns that are remarkably similar to those seen on larger scales in elliptical galaxies and in gas-rich merger simulations. The kinematics suggests the presence of two components in the M32 nucleus, a dominant disk overlying a pressure supported component. I discuss possible formation scenarios for the M32 nucleus in the context of the kinematic data as well as previous stellar population studies. The kinematic measurements presented here are the highest quality available for the nucleus of M32, and may be useful for any future dynamical models of this benchmark system.
