description: The effects of four-quasiparticle configurations and time-odd interactions are investigated in the framework of configuration interaction projected density functional theory by taking the yrast states of 60Fe as examples. Based on the universal PC-PK1 density functional, the energies of the yrast states with spin up to 20\hbar and the available B(E2) transition probabilities are well reproduced. The yrast states are predicted to be of four-quasiparticle structure above spin I = 16\hbar. The inclusion of the time-odd interactions increases the kinetic moments of inertia and delays the appearance of the first band crossing, and, thus, improves the description of the data.

description: The study evaluated the marketing channel efficiency and choice analysis of beef in Imo state, identify the marketing channels, assess the determinants of choice of marketing channels and identify the constraints faced by small-holder beef traders in the study area. Purposive and simple random sampling techniques were employed to select thirty-two (32) wholesalers, seventy-five (75) retailers and thirteen (13) Speculators. Descriptive statistics, Multinomial logit regression. Results showed that majority of the beef traders 98% were males, with the mean age of 43 years and mean household size of 4 persons. The result further outlines the prominent marketing channels in area to include Ranches – Slaughterhouse 72.8%, Slaughterhouse – Retailers 70.8%, Retailers – Consumers 67.8% and Slaughter – Wholesalers 58.5%. The result of multinomial results on the determinants of choice of marketing channels shows that the combine effects of age and access to market information had a positive influence on choice of marketing channels while the combine effects of level of education, household size and cost storage facilities had a negative influence on their choice of market channels. High cost of transportation, price fluctuations, bad roads and high market charges are the predominant constraints to small-holder beef traders in the study area. The Government and policy makers should implement policies that will improve market infrastructure, construct good roads, and cut down some of the unnecessary charges which pose a constraint to beef marketing in the study area. Efforts to keep agricultural prices stable all year round through price stabilization policy, traders’ co-operatives should dialog with government and market leaders to find possible ways to reduce the market charges and price fluctuations. Government should provide lasting solution to ensure the safe transportation of agricultural produces in Nigeria.

description: We present a method to determine nitrogen abundance ratios with respect to iron ([N/Fe]) from molecular CN-band features observed in low-resolution ($R \sim$ 2000) stellar spectra obtained by the Sloan Digital Sky Survey (SDSS) and the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). Various tests are carried out to check the systematic and random errors of our technique, and the impact of signal-to-noise (S/N) ratios of stellar spectra on the determined [N/Fe]. We find that the uncertainty of our derived [N/Fe] is less than 0.3 dex for S/N ratios larger than 10 in the ranges $T_{eff}$ = [4000, 6000] K, log g = [0.0, 3.5], [Fe/H] = [--3.0, 0.0], [C/Fe] = [--1.0, +4.5], and [N/Fe] = [--1.0, +4.5], the parameter space that we are interested in to identify N-enhanced stars in the Galactic halo. A star-by-star comparison with a sample of stars with [N/Fe] estimates available from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) also suggests a similar level of uncertainty in our measured [N/Fe], after removing its systematic error. Based on these results, we conclude that our method is able to reproduce [N/Fe] from low-resolution spectroscopic data, with an uncertainty sufficiently small to discover N-rich stars that presumably originated from disrupted Galactic globular clusters.

description: Discrete symmetries are widely imposed in particle theories. It is well-known that the spontaneous breaking of discrete symmetries leads to domain walls. Current studies of domain walls have focused on those from the spontaneous breaking of a $Z_2$ symmetry. Larger discrete symmetries have multiple degenerate vacua, leading to the domain walls in principle different from the simplest $Z_2$ domain wall. We take domain walls from $Z_N$ symmetry breaking as an illustrative study, and study in detail the $Z_3$ case, in which semi-analytical results for the tension and thickness of domain walls are derived. Explicit symmetry breaking terms lead to the dynamics of domain walls collapsing more complicated than the $Z_2$ case. Gravitational wave signals deviate from those from $Z_2$ domain walls.

description: The direct detection and imaging of exoplanets requires the use of high-contrast adaptive optics (AO). In these systems quasi-static aberrations need to be highly corrected and calibrated. In order to achieve this, the pupil-modulated point-diffraction interferometer (m-PDI), was presented in an earlier paper. This present paper focuses on m-PDI concept validation through three experiments. First, the instrument's accuracy and dynamic range are characterised by measuring the spatial transfer function at all spatial frequencies and at different amplitudes. Then, using visible monochromatic light, an adaptive optics control loop is closed on the system's systematic bias to test for precision and completeness. In a central section of the pupil with 72% of the total radius the residual error is 7.7nm-rms. Finally, the control loop is run using polychromatic light with a spectral FWHM of 77nm around the R-band. The control loop shows no drop in performance with respect to the monochromatic case, reaching a final Strehl ratio larger than 0.7.

description: Wearable electrochemical sensors have aroused tremendous attention due to their potential for in situ and continuous glucose monitoring. Glucose is a critical risk indicator of diabetes, and continuous glucose monitoring has been proven remarkable to reduce the deterioration of diabetes and prevent secondary complications. Herein, we present a novel biocompatible wearable electrochemical sensor for glucose monitoring in ISF. Compared with previous glucose sensors, our study introduces an innovative combination of 3D-printed HMNs and SANs to address the key limitations in existing technologies. HMNs are fabricated by biocompatible resin, allowing minimally invasive sampling for ISF and ensuring safe interaction with the skin without irritation and toxicity concerns. The incorporation of SANs significantly boosts the sensitivity and selectivity of electrochemical sensing, offering a wide linear range of 0.1 μM to 40 mM for glucose. The integration of 3D-printed HMNs and a finger-activated pump demonstrates the ISF extraction capability in a biocompatible and minimally invasive approach, which is validated through the sampling of artificial ISF from skin-mimicking phantom gel “in vivo”. Furthermore, the sensor is coupled with a potentiostat, enabling real-time and wireless data transmission to a smartphone app to provide immediate results of the glucose levels. Beyond glucose detection, this versatile platform holds great potential for expanding the detection of a wide range of biomarkers in ISF. This research aims to develop and validate the wireless sensor, showcasing its sensitivity and selectivity using a skin-mimicking phantom gel, thereby laying the foundation for future advancements in wearable biosensors.

description: We present methods to (i) graphically identify robust redshifts using emission lines in the (sub)mm regime, (ii) evaluate the capabilities of different (sub)mm practices for measuring spectroscopic redshifts, and (iii) optimise future (sub)mm observations towards increasing the fraction of robust redshifts. Using this publicly-available code (https://github.com/tjlcbakx/redshift-search-graphs), we discuss scenarios where robust redshifts can be identified using both single- and multiple-line detections, as well as scenarios where the redshift remains ambiguous, even after the detection of multiple lines. Using the redshift distribution of (sub)mm samples, we quantify the efficiencies of various practices for measuring spectroscopic redshifts, including interferometers, as well as existing and future instruments specifically designed for redshift searches. Finally, we provide a method to optimise the observation strategy for future (sub)mm spectroscopic redshift searches with the Atacama Large Millimetre/submillimetre Array, where 2 mm proves indispensable for robust redshifts in the z = 2 - 4 region.

Die Medien sind voll von negativen Schlagzeilen über Pädophile, und Menschen mit einer pädophilen Neigung haben einen schweren Stand in unserer Gesellschaft. Doch was ist Pädophilie wirklich? Wie entsteht sie? Und ist jeder Pädophile auch ein Kinderschänder? Pädophilie ist eine sexuelle Neigung wie Homosexualität, und doch muss man sie völlig anders betrachten. Gibt es Möglichkeiten, die sexuelle Neigung zu beeinflussen, damit Betroffene ein normales Leben führen können? Zudem stellt sich die Frage, wie sexuelle Übergriffe an Kindern verhindert werden können. Das Phänomen der Pädophilie stellt in vieler Hinsicht einen Wertekonflikt für die Sozialarbeit dar. Der Grat ist schmal. Auf der einen Seite stehen das Ausleben der eigenen Sexualität sowie der Schutz der Pädophilen vor gesellschaftlicher Stigmatisierung, auf der anderen Seite wehrlose Kinder, welche geschützt werden müssen. Die vorliegende Bachelor-Arbeit versucht sich Klarheit über das Krankheitsbild der Pädophilie zu verschaffen und zeigt Möglichkeiten für die Sozialarbeit auf, sich für Betroffene einzusetzen, ohne dabei den Schutz der Kinder ausser Acht zu lassen.

description: We use results of a survey for low-surface-gravity stars in Galactic (and LMC) globular clusters to show that "yellow" post-asymptotic-giant-branch (yPAGB) stars are likely to be excellent extragalactic standard candles, capable of producing distances to early-type galaxies that are accurate to a few percent. We show that the mean bolometric magnitude of the 10 known yPAGB stars in globular clusters is = -3.38 +/- 0.03, a value that is ~0.2 mag brighter than that predicted from the latest post-horizontal-branch evolutionary tracks. More importantly, we show that the observed dispersion in the distribution is only 0.10 mag, i.e., smaller than the scatter for individual Cepheids. We describe the physics that can produce such a small dispersion, and show that, if one restricts surveys to the color range 0 < (B-V)0 < 0.5, then samples of non-variable yPAGB stars can be identified quite easily with a minimum of contamination. The bright absolute V magnitudes of these stars ( = -3.37) make them, by far, the visually brightest objects in old stellar populations and ideal Population II standard candles for measurements out to ~10 Mpc with current instrumentation. A Hubble Space Telescope survey in the halos of galaxies in the M81 and Sculptor groups could therefore serve as an effective cross-check on both the Cepheid and TRGB distance scales.

description: We carry out high-energy studies of the region of the Galactic TeV source 3HWC J1954+286, whose location coincides with those of PSR~J1954+2836 and supernova remnant (SNR) G65.1+0.6. Analyzing the GeV $γ$-ray data obtained with the Large Area Telescope (LAT) onboard {\it the Fermi Gamma-ray Space Telescope}, we are able to separate the pulsar's emission from that of the region. Excess power-law--like emission of a $\sim 6σ$ significance level at the region is found, for which we explain as arising from the SNR~G65.1+0.6. Given the low-significance detection, either a hadronic or a leptonic model can provide a fit to the power-law spectrum. Considering the properties of the pulsar and the SNR, we discuss the possible origin of the TeV source, and suggest that it is likely the TeV halo associated with the pulsar.

description: We show through intensive simulations that the paradigmatic features of anomalous diffusion are indeed the features of a (continuous-time) random walk driven by two different Markovian hopping-trap mechanisms. If $p \in (0,1/2)$ and $1-p$ are the probabilities of occurrence of each Markovian mechanism, then the anomalousness parameter $β\in (0,1)$ results to be $β\simeq 1 - 1/\{1 + \log[(1-p)/p]\}$. Ensemble and single-particle observables of this model have been studied and they match the main characteristics of anomalous diffusion as they are typically measured in living systems. In particular, the celebrated transition of the walker's distribution from exponential to stretched-exponential and finally to Gaussian distribution is displayed by including also the Brownian yet non-Gaussian interval.

description: We present LyMAS2, an improved version of the "Lyman-α Mass Association Scheme" aiming at predicting the large-scale 3d clustering statistics of the Lyman-α forest (Ly-α) from moderate resolution simulations of the dark matter (DM) distribution, with prior calibrations from high resolution hydrodynamical simulations of smaller volumes. In this study, calibrations are derived from the Horizon-AGN suite simulations, (100 Mpc/h)^3 comoving volume, using Wiener filtering, combining information from dark matter density and velocity fields (i.e. velocity dispersion, vorticity, line of sight 1d-divergence and 3d-divergence). All new predictions have been done at z=2.5 in redshift-space, while considering the spectral resolution of the SDSS-III BOSS Survey and different dark matter smoothing (0.3, 0.5 and 1.0 Mpc/h comoving). We have tried different combinations of dark matter fields and found that LyMAS2, applied to the Horizon-noAGN dark matter fields, significantly improves the predictions of the Ly-α 3d clustering statistics, especially when the DM overdensity is associated with the velocity dispersion or the vorticity fields. Compared to the hydrodynamical simulation trends, the 2-point correlation functions of pseudo-spectra generated with LyMAS2 can be recovered with relative differences of ~5% even for high angles, the flux 1d power spectrum (along the light of sight) with ~2% and the flux 1d probability distribution function exactly. Finally, we have produced several large mock BOSS spectra (1.0 and 1.5 Gpc/h) expected to lead to much more reliable and accurate theoretical predictions.

description: It is critical for James Webb Space Telescope (JWST) science that instrumental units are converted to physical units. We detail the design of the JWST absolute flux calibration program that has the core goal of ensuring a robust flux calibration internal to and between all the science instruments for both point and extended source science. This program will observe a sample of calibration stars that have been extensively vetted based mainly on Hubble Space Telescope, Spitzer Space Telescope, and Transiting Exoplanet Survey Satellite observations. The program uses multiple stars of three different, well understood types (hot stars, A dwarfs, and solar analogs) to allow for the statistical (within a type) and systematic (between types) uncertainties to be quantified. The program explicitly includes observations to calibrate every instrument mode, further vet the set of calibration stars, measure the instrumental repeatability, measure the relative calibration between subarrays and full frame, and check the relative calibration between faint and bright stars. For photometry, we have set up our calibration to directly support both the convention based on the band average flux density and the convention based on the flux density at a fixed wavelength.

description: We present new observations of CO J=2-1 emission from the protoplanetary disk around TW Hya. Emission is detected out to 240 au (4") and found to exhibit azimuthal variations up to 20% beyond 180 au (3"), with the west side of the disk brighter than the east. This asymmetry is interpreted as tracing the shadow previously seen in scattered light. A reanalysis of the multi-epoch observations of the dust shadow in scattered light from Debes et al. (2017) suggests that an oscillatory motion would provide a better model of the temporal evolution of the dust shadow rather than orbital motion. Both models predict an angular offset between the dust shadow and the gas shadow of up to ~100 deg. We attribute this offset to the finite rate at which dust grains and gas molecules can exchange heat, dominated by the collisional rate between gas molecules and dust grains, $t_{\rm coll}$. The angular offsets derived are equivalent to collisional timescales that range from the near instantaneous up to $t_{\rm coll}$ ~ 10 years, depending on whether a straight or a curved dust shadow, as suggested by HST observations reported by Debes et al. (2017), is adopted. The inferred range of $t_{\rm coll}$ are consistent with those predictions based on representative gas densities, temperatures, gas-to-dust ratios and grain sizes. These results represent the first time empirical constraints can be placed on $t_{\rm coll}$.

description: An ultra-stripped supernova (USSN) is a type of core-collapse SN explosion proposed to be a candidate formation site of a double neutron star (DNS) binary. We investigate the dynamical evolution of an ultra-stripped supernova remnant (USSNR), which should host a DNS at its center. By accounting for the mass-loss history of the progenitor binary using a model developed by a previous study, we construct the large-scale structure of the {circumstellar medium (CSM)} up to a radius $\sim 100\,{\rm pc}$, and simulate the explosion and subsequent evolution of a USSN surrounded by such a CSM environment. We find that the CSM encompasses an extended region characterized by a hot plasma with a temperature $\sim 10^8\,$K located around the termination shock of the wind from the progenitor binary ($\sim 10\,$pc), and the USSNR blastwave is drastically weakened while penetrating through this hot plasma. Radio continuum emission from a young USSNR is sufficiently bright to be detectable if it inhabits our Galaxy but faint compared to the observed Galactic SNRs, and thereafter declines in luminosity through adiabatic cooling. Within our parameter space, USSNRs typically exhibit a low radio luminosity and surface brightness compared to the known Galactic SNRs. Due to the small event rate of USSNe and their relatively short observable lifespan, we calculate that USSNRs account for only $\sim 0.1$-$1$ % of the total SNR population. This is consistent with the fact that no SNR hosting a DNS binary has been discovered in the Milky Way so far.

description: Sparse aperture masking interferometry (SAM) is a high resolution observing technique that allows for imaging at and beyond a telescope's diffraction limit. The technique is ideal for searching for stellar companions at small separations from their host star; however, previous analysis of SAM observations of young stars surrounded by dusty disks have had difficulties disentangling planet and extended disk emission. We analyse VLT/SPHERE-IRDIS SAM observations of the transition disk LkCa\,15, model the extended disk emission, probe for planets at small separations, and improve contrast limits for planets. We fit geometrical models directly to the interferometric observables and recover previously observed extended disk emission. We use dynamic nested sampling to estimate uncertainties on our model parameters and to calculate evidences to perform model comparison. We compare our extended disk emission models against point source models to robustly conclude that the system is dominated by extended emission within 50 au. We report detections of two previously observed asymmetric rings at $\sim$17 au and $\sim$45 au. The peak brightness location of each model ring is consistent with the previous observations. We also, for the first time with imaging, robustly recover an elliptical Gaussian inner disk, previously inferred via SED fitting. This inner disk has a FWHM of ~5 au and a similar inclination and orientation as the outer rings. Finally, we recover no clear evidence for candidate planets. By modelling the extended disk emission, we are able to place a lower limit on the near infrared companion contrast of at least 1000.

description: Temperature and photoperiod are two major environmental determinants that affect the flowering time. The information on the effect of temperature and photoperiod on flowering response in pigeonpea is limited and needs updating for new genotypes. The present study aimed to assess the reliability of the Nonlinear least square broken stick model to quantify photothermal effects in pigeonpea (Cajanus cajan (L.) Millsp.) genotypes. Data at 50 % flowering (FL) from pot, field, and temperaturecontrolled glasshouse experiments under eight sowing dates were analysed using regression models to describe the individual effect of temperature and photoperiod and photothermal models to quantify the combined effect. The critical photoperiod (Pce) and optimum temperature (To)predicted by the Nonlinear broken stick model for 50 % FL ranged from 12.4-13.4 h and 21.0 23.5 °C, respectively. The higher Pce reported for extra-early flowering genotype (QPL 1001) indicates that their insensitiveness to a range of photoperiod regimes compared to QPL 941 and ICP 14425 (medium duration). Further, the results also revealed that the time to 50 % FL of genotype QPL 1001 was strongly sensitive to the temperature at sub-optimal range (T < To), with warmer temperatures accelerating reproductive development. In contrast, QPL941 and ICP 14425 were sensitive to supraoptimal temperature (T > To), with flowering being delayed in warmer temperatures. The parameters (To and Pce) derived from Nonlinear least square broken stick model can be used as a proxy to identify photoperiod insensitivity in pigeopea genotypes.

description: Mid-infrared spectroscopy is one of the few ways to observe the composition of the terrestial planet forming zone, the inner few au, of proto-planetary disks. The species currently detected in the disk atmosphere, for example CO, CO2, H2O and C2H2, are theoretically enough to constrain the C/O ratio in the disk surface. However, thermo-chemical models have difficulties in reproducing the full array of detected species in the mid-infrared simultaneously. In an effort to get closer to the observed spectra, we have included water UV-shielding as well as more efficient chemical heating into thermo-chemical code Dust And Lines. We find that both are required to match the observed emission spectrum. Efficient chemical heating, in addition to traditional heating from UV photons, is necessary to elevate the temperature of the water emitting layer to match the observed excitation temperature of water. We find that water UV-shielding stops UV photons from reaching deep into the disk, cooling down the lower layers with higher column. These two effects create a hot emitting layer of water with a column of 1-10$\times 10^{18}$ cm$^{-2}$. This is only 1-10% of the water column above the dust $τ=1$ surface at mid-infrared wavelengths in the models and represents <1% of the total water column.

description: In this article we continue the work on translating elements of the perturbative quantum field theory defined on Minkowski spacetime into the background independent framework of Loop Quantum Gravity. We present the construction of r-Fock measures for $SU(N)$ gauge theories and provide a relation between these new r-Fock measures and the difeomorphism invariant measure used in loop quantum gravity.

description: Using $I$-band images of 35 nearby ($z<0.1$) type 1 active galactic nuclei (AGNs) obtained with Hubble Space Telescope, selected from the 70-month Swift-BAT X-ray source catalog, we investigate the photometric properties of the host galaxies. With a careful treatment of the point-spread function (PSF) model and imaging decomposition, we robustly measure the $I$-band brightness and the effective radius of bulges in our sample. Along with black hole (BH) mass estimates from single-epoch spectroscopic data, we present the relation between BH mass and $I$-band bulge luminosity ($M_{\rm BH}-M_{I,\rm bul}$ relation) of our sample AGNs. We find that our sample lies offset from the $M_{\rm BH}-M_{I,\rm bul}$ relation of inactive galaxies by 0.4 dex, i.e., at a given bulge luminosity, the BH mass of our sample is systematically smaller than that of inactive galaxies. We also demonstrate that the zero point offset in the $M_{\rm BH}-M_{I,\rm bul}$ relation with respect to inactive galaxies is correlated with the Eddington ratio. Based on the Kormendy relation, we find that the mean surface brightness of ellipticals and classical bulges in our sample is comparable to that of normal galaxies, revealing that bulge brightness is not enhanced in our sample. As a result, we conclude that the deviation in the $M_{\rm BH}-M_{I,\rm bul}$ relation from inactive galaxies is possibly because the scaling factor in the virial BH mass estimator depends on the Eddington ratio.

description: This essay considers how policy thinking about culture has been steadily transformed into an overwhelmingly economic subject matter whose central trope is the “creative economy”. The development of current ideas and their background are discussed. Policy ideas first fully developed in the UK have had a global resonance: the illustrative examples of the European Union and the United Nations are discussed. The embedding of creative economy thinking in British cultural institutions such as the BBC and cultural support bodies is illustrated. The impact of current orthodoxy on academic institutions and research is also considered. Countervailing trends are weak. New thinking is now required.

description: Despite the exciting performance, Transformer is criticized for its excessive parameters and computation cost. However, compressing Transformer remains as an open problem due to its internal complexity of the layer designs, i.e., Multi-Head Attention (MHA) and Feed-Forward Network (FFN). To address this issue, we introduce Group-wise Transformation towards a universal yet lightweight Transformer for vision-and-language tasks, termed as LW-Transformer. LW-Transformer applies Group-wise Transformation to reduce both the parameters and computations of Transformer, while also preserving its two main properties, i.e., the efficient attention modeling on diverse subspaces of MHA, and the expanding-scaling feature transformation of FFN. We apply LW-Transformer to a set of Transformer-based networks, and quantitatively measure them on three vision-and-language tasks and six benchmark datasets. Experimental results show that while saving a large number of parameters and computations, LW-Transformer achieves very competitive performance against the original Transformer networks for vision-and-language tasks. To examine the generalization ability, we also apply our optimization strategy to a recently proposed image Transformer called Swin-Transformer for image classification, where the effectiveness can be also confirmed

description: A large family of nonsingular rational solutions of the Kadomtsev-Petviashvili (KP) I equation are investigated. These solutions are constructed via the Gramian method and are identified as points in a complex Grassmannian. Each solution is a traveling wave moving with a uniform background velocity but have multiple peaks which evolve at a slower time scale in the co-moving frame. For large times, these peaks separate and form well-defined wave patterns in the $xy$-plane. The pattern formation are described by the roots of well-known polynomials arising in the study of rational solutions of Painlevé II and IV equations. This family of solutions are shown to be described by the classical Schur functions associated with partitions of integers and irreducible representations of the symmetric group of $N$ objects. It is then shown that there exists a one-to-one correspondence between the KPI rational solutions considered in this article and partitions of a positive integer $N$.

description: We have statistically analyzed 379 radio-loud (RL) CMEs and their associated flares during the period 1996 - 2019 covering both solar cycles (SC) 23 and 24. We classified them into two sets of populations based on the observation period: i) 235 events belong to SC 23 (August 1996 - December 2008) and ii) 144 events belong to SC 24 (January 2009 - December 2019). The average residual acceleration of RL CMEs in SC 24 (--17.39 $\pm$ 43.51 m s$^{-2}$) is two times lower than that of the RL CMEs in SC 23 (--8.29 $\pm$ 36.23 m s$^{-2}$), which means that deceleration of RL CMEs in SC 24 is twice as fast as in SC 23. RL CMEs of SC 23 (1443 $\pm$ 504 km s$^{-1}$; 13.82 $\pm$ 7.40 \emph{R}$_{\circledcirc}$) reach their peak speed at higher altitudes than RL CMEs of SC 24 (1920 $\pm$ 649 km s$^{-1}$; 12.51 $\pm$ 7.41 \emph{R}$_{\circledcirc}$).We also observed that the mean apparent widths of RL CMEs in SC 23 are less than in SC 24which is statistically significant. SC 23 has a lower average CME nose height (3.85 \emph{R}$_{\circledcirc}$) at the start time of DH type II bursts than that of SC 24 (3.46 \emph{R}$_{\circledcirc}$). The starting frequencies of DH type II bursts associated with RL CMEs for SC 24 are significantly larger (formed at lower heights) than that of SC 23. We found that there is a good correlation between the drift rates and the mid-frequencies of DH type II radio bursts for both the solar cycles (\emph{R} = 0.80, $ε$ = 1.53). Most of the RL CMEs kinematics and their associated solar flare properties are found similar for SC 23 and SC 24. We concluded that the reduced total pressure in the heliosphere for SC 24 enables RL CMEs to expand wider and decelerate faster, resulting in DH type II radio emissions at lower heights than SC 23.
