description: Inspired by the observation of the doubly charmed state $T_{cc}$ and following theoretical studies on its spectroscopic parameters, we investigate its magnetic dipole moment assigning it the quantum numbers $J^P=1^+$ and both the compact diquark-antidiquark and molecular structures in the framework of the light-cone QCD. We also calculate the magnetic dipole moment of the theoretically predicted singly charmed state, $Z_V^{++}$, with two units of electric charge and the quantum numbers $J^P=1^-$ in diquark-antidiquark picture. The numerical results are obtained as $μ_{T_{cc}^+-Di} =0.66^{+0.34}_{-0.23}~μ_N$, $ μ_{T_{cc}^+-Mol} =0.43^{+0.23}_{-0.22}~μ_N $ and $μ_{Z_{V}^{++}} =3.35^{+0.89}_{-0.73} ~μ_N$. These results may be checked via other phenomenological approaches. The obtained results may be useful in exact determinations of the natures of these states.

description: Electronic Health Record (EHR) systems provide critical, rich and valuable information at high frequency. One of the most exciting applications of EHR data is in developing a real-time mortality warning system with tools from survival analysis. However, most of the survival analysis methods used recently are based on (semi)parametric models using static covariates. These models do not take advantage of the information conveyed by the time-varying EHR data. In this work, we present an application of a highly scalable survival analysis method, BoXHED 2.0 to develop a real-time in-ICU mortality warning indicator based on the MIMIC IV data set. Importantly, BoXHED can incorporate time-dependent covariates in a fully nonparametric manner and is backed by theory. Our in-ICU mortality model achieves an AUC-PRC of 0.41 and AUC-ROC of 0.83 out of sample, demonstrating the benefit of real-time monitoring.
The Palomar/Keck Adaptive Optics Survey of Young Solar Analogs: Evidence for a Universal Companion Mass Function

description: We present results from an adaptive optics survey for substellar and stellar companions to Sun-like stars. The survey targeted 266 F5-K5 stars in the 3Myr to 3Gyr age range with distances of 10-190pc. Results from the survey include the discovery of two brown dwarf companions (HD49197B and HD203030B), 24 new stellar binaries, and a triple system. We infer that the frequency of 0.012-0.072Msun brown dwarfs in 28-1590AU orbits around young solar analogs is 3.2% (+3.1%,-2.7%; 2sigma limits). The result demonstrates that the deficiency of substellar companions at wide orbital separations from Sun-like stars is less pronounced than in the radial velocity "brown dwarf desert." We infer that the mass distribution of companions in 28-1590AU orbits around solar-mass stars follows a continuous dN/dM_2 ~ M_2^(-0.4) relation over the 0.01-1.0Msun secondary mass range. While this functional form is similar to that for <0.1Msun isolated objects, over the entire 0.01-1.0Msun range the mass functions of companions and of isolated objects differ significantly. Based on this conclusion and on similar results from other direct imaging and radial velocity companion surveys in the literature, we argue that the companion mass function follows the same universal form over the entire range between 0-1590AU in orbital semi-major axis and 0.01-20Msun in companion mass. In this context, the relative dearth of substellar versus stellar secondaries at all orbital separations arises naturally from the inferred form of the companion mass function.

description: Metaheuristics (MHs) in general and Evolutionary Algorithms (EAs) in particular are well known tools for successful optimization of difficult problems. But when is their application meaningful and how does one approach such a project as a novice? How do you avoid beginner's mistakes or use the design possibilities of a metaheuristic search as efficiently as possible? This paper tries to give answers to these questions based on 30 years of research and application of the Evolutionary Algorithm GLEAM and its memetic extension HyGLEAM. Most of the experience gathered and discussed here can also be applied to the use of other metaheuristics such as ant algorithms or particle swarm optimization. This paper addresses users with basic knowledge of MHs in general and EAs in particular who want to apply them in an optimization project. For this purpose, a number of questions that arise in the course of such a project are addressed. At the end, some non-technical project management issues are discussed, whose importance for project success is often underestimated.

description: In this paper, we study the behavior of the pseudo-Newtonian force and potential about a higher dimensional rotating black hole. We obtain conditions for the force character from an attractive to repulsive. We also find the conditions under which force attains a maximum value. The results of this paper generalizes the already found structure of force and potential about a five dimensional rotating black hole. It is interesting to note that we recover the five dimensional results under a special case.

description: It is well known that the effect of top quark loop corrections in the axial part of quark form factors (FF) does not decouple in the large top mass or low energy limit due to the presence of the axial-anomaly type diagrams. The top-loop induced singlet-type contribution should be included in addition to the purely massless result for quark FFs when applied to physics in the low energy region, both for the non-decoupling mass logarithms and for an appropriate renormalization scale dependence. In this work, we have numerically computed the so-called singlet contribution to quark FFs with the exact top quark mass dependence over the full kinematic range. We discuss in detail the renormalization formulae of the individual subsets of the singlet contribution to an axial quark FF with a particular flavor, as well as the renormalization group equations that govern their individual scale dependence. Finally we have extracted the 3-loop Wilson coefficient in the low energy effective Lagrangian, renormalized in a non-$\overline{\mathrm{MS}}$ scheme and constructed to encode the leading large mass approximation of our exact results for singlet quark FFs. We have also examined the accuracy of the approximation in the low energy region.

Some referential and causal attributions underlying stereotype content
Creators: name: McTiernan, Timothy John
Publisher: name: University of British Columbia
Year: 2010

description: This study is based on the theoretical assumption that a detailed understanding of the nature of stereotypes entails more than an analysis of the content of stereotype descriptions. It must also include a study of the range of target group members, situations, and behaviours to which people generalize their stereotypes (referential attributions), and an examination of judgements regarding the causes of stereotype traits (causal attributions). A check list stereotyping task was combined with a multivariate judgement task in order to examine the causal and referential attributions underlying individuals' stereotype descriptions. Two hundred and forty respondents, forming four distinct subgroups, described either an outgroup or a target group to which they belonged. They then made a number of attributions about their descriptions. The target groups, defined broadly in environmental terms, were: Big City People, Small Town People, Conservation-rninded People, and Development-minded People. The results indicated that the referential attributions provided by the respondents did not vary with the changes in content between the different stereotypes. They were unrelated to the causal attributions, and they were unaffected by the respondents' membership status vis-a-vis the target groups. Rather, the referential attributions reflected the use of a representativeness rule and a distinctiveness criterion in the selection of trait descriptors. The respondents attributed their stereotype traits to a large proportion of target members, to many of their behaviours, and to many situations involving target members. The individuals judged these stereotype traits to be characteristics that distinguished the targets from people in general. Learning was rated as having a greater effect than inheritance as a causal agent in trait development. There were reliable sub-sample differences in the magnitude of this outcome. The study contained a replication condition. Two different types of target groups were employed and the data related to each type were analyzed independently. While the findings regarding the referential and causal attributions generalized across these two sets of analyses for the most part, the traditionally measured content-related results did not replicate. A review of this disparity indicated that caution should be exercised in the selection of targets for stereotype research and appropriate efforts should be made to ensure that the measuring instruments employed best suit the theoretical issue being addressed.
High-Mass X-Ray Binaries with Be Donors as Ultraluminous X-Ray Sources

description: Since the detection of X-ray pulses from ultraluminous X-ray sources (ULXs) in 2014, neutron stars have been considered as their central objects. However, it remains unclear how neutron stars can be brighter than the Eddington luminosity, and no unified view exists on the magnetic field of neutron stars and the degree of beaming. Recent observations suggest that some X-ray pulsating ULXs have Be-type donors, and some of them occupy the same region as Be-type high-mass X-ray binaries (Be-HMXBs) on the Corbet diagram, which reveals the relation between spin and orbital periods. This suggests that at least some ULXs are special cases of Be-HMXBs. In this study, we use the framework of mass-accretion models for Be-HMXBs to investigate the conditions under which neutron stars achieve mass-accretion rates beyond the Eddington limit and become observable as ULXs. We show that a Be-HMXB may become a ULX if the magnetic field of the neutron star and the density of the Be disc meet certain conditions. We also show that, although a stronger magnetic field increases the brightness of a neutron star ULX with a Be donor, its brightness cannot exceed the Eddington limit by a more than a factor of ${\approx} 50$. Finally, we propose a scenario whereby some normal Be-HMXBs may evolve into ULXs as the donor evolves into a giant.

description: We demonstrate superradiant conversion between a two-mode collective atomic state and a single-mode light field in an elongated cloud of Bose-condensed atoms. Two off-resonant write beams induce superradiant Raman scattering, producing two independent coherence gratings with a different wave vector in the cloud. By applying phase-matched read beams after a controllable delay, the gratings can be selectively converted into the light field also in a superradiant way. Due to the large cooperativity parameter and the small velocity width of the condensate, a high conversion efficiency of $> 70$ % and a long storage time of $> 120$ $μ$s were achieved.

description: Obecnie jednym z najważniejszych wyzwań dla europejskiej kultury akademickiej jest rozwój zasad uczciwości akademickiej (Research Integrity – RI) i etyki badań (Research Ethics – RE) na uniwersytetach. W tekście przedstawiono dwie główne strategie zakorzenienia badań naukowych i innowacji na uczelniach wyższych. Pierwsza z nich łączy liberalno-technokratyczny model uczelni z indywidualistycznym podejściem do praktyk naukowych – etyka badawcza i uczciwość badawcza są częścią ścieżek osobistych karier edukacyjnych i zawodowych. Druga strategia wynika z definicji nauki jako wspólnej wartości i odnosi się do zbiorowej wizji uczelni – budowanie kultury rzetelności naukowej jest podporządkowane realizacji społecznych ról nauki i etosu naukowego. W obliczu masowego rozwoju szkolnictwa wyższego zarówno wizje uczelni, jak i sama idea jednego modelu etyki są utopijne – to model zarazem pożądany, jak i nieosiągalny. Prezentowany artykuł jest oparty na wynikach badań przeprowadzonych w ramach projektu Path2Integrity, finansowanego z programu Horyzont 2020.

description: In the heavy quark limit of QCD, using the Operator Product Expansion, the formalism of Falk for hadrons or arbitrary spin, and the non-forward amplitude, as proposed by Uraltsev, we formulate sum rules involving the Isgur-Wise function $ξ_Λ (w)$ of the baryon transition $Λ_b \to Λ_c \ell \overlineν_{\ell}$, where the light cloud has $j^P=0^+$ for both initial and final baryons. We recover the lower bound for the slope $ρ_Λ^2 = - ξ'_Λ(1) \geq 0$ obtained by Isgur et al., and we generalize it by demonstrating that the IW function $ξ_Λ (w)$ is an alternate series in powers of $(w-1)$, i.e. $(-1)^n ξ_Λ^{(n)} (1) \geq 0$. Moreover, exploiting systematically the sum rules, we get an improved lower bound for the curvature in terms of the slope, $σ_Λ^2 = ξ"_Λ(1) \geq {3 \over 5} [ρ_Λ^2 + (ρ_Λ^2)^2]$. This bound constrains the shape of the Isgur-Wise function and it will be compelling in the analysis of future precise data on the differential rate of the baryon semileptonic decay $Λ_b \to Λ_c \ell \overlineν_{\ell}$, that has a large measured branching ratio, of about 5%.

description: We present ULTRACAM multiband optical photometry of two transitional millisecond pulsars, PSR J1023+0038 and PSR J1227$-$4853, taken while both were in their radio pulsar states. The light curves show significant asymmetry about the flux maxima in all observed bands, suggesting an asymmetric source of heating in the system. We model the light curves using the Icarus binary code, using models with an additional "hot spot" heating contribution and an anisotropic heat redistribution model to treat the asymmetry. Our modelling reveals companion stars with under-filled Roche lobes in both PSRs J1023+0038 and J1227$-$4853, with Roche lobe filling factors in the range $f \sim 0.82-0.92$. While the volume-averaged filling factors are closer to unity, significant under-filling is unexpected from tMSPs as they must rapidly over-fill their Roche lobes to start transferring mass, which occurs on timescale of weeks or months. We discuss the motivation and validity of our extensions to the models and the implications of the under-filled Roche lobe, and suggest future work to further investigate the role of the filling factor in the tMSP cycle.

description: The dynamics of magnetic reconnection in the solar current sheet (CS) is studied by high-resolution 2.5-dimensional MHD simulation. With the commence of magnetic reconnection, a number of magnetic islands are formed intermittently and move quickly upward and downward along the CS. When colliding with the semi-closed flux of flare loops, the downflow islands cause a second reconnection with a rate even comparable with that in the main CS. Though the time-integrated magnetic energy release is still dominated by the reconnection in main CS, the second reconnection can release substantial magnetic energy, annihilating the main islands and generating secondary islands with various scales at the flare loop top. The distribution function of the flux of the second islands is found to follow a power-law varying from $f\left(ψ\right)\simψ^{-1}$ (small scale) to $ψ^{-2}$ (large scale), which seems to be independent with background plasma $β$ and if including thermal conduction. However, the spatial scale and the strength of the termination shocks driven by main reconnection outflows or islands decrease if $β$ increases or thermal conduction is included. We suggest that the annihilation of magnetic islands at the flare loop top, which is not included in the standard flare model, plays a non-negligible role in releasing magnetic energy to heat flare plasma and accelerate particles.

description: We explore the possibility to detect the continuum radio signal from direct collapse black holes (DCBHs) by upcoming radio telescopes such as the SKA and ngVLA, assuming that after formation they can launch and sustain powerful jets at the accretion stage. We assume that the high-$z$ DCBHs have similar jet properties as the observed radio-loud AGNs, then use a jet model to predict their radio flux detectability. If the jet power $P_{\rm jet}\gtrsim10^{42-43}$ erg s$^{-1}$, it can be detectable by SKA/ngVLA, depending on the jet inclination angle. Considering the relation between jet power and black hole mass and spin, generally, jetted DCBHs with mass $\gtrsim10^5~M_\odot$ can be detected. For a total jetted DCBH number density of $\sim2.5\times10^{-3}$ Mpc$^{-3}$ at $z=10$, about 100 deg$^{-2}z^{-1}$ DCBHs are expected to be above the detection threshold of SKA1-mid (100 hours integration). If the jet "blob" emitting most of the radio signal is dense and highly relativistic, then the DCBH would only feebly emit in the SKA-low band, because of self-synchrotron absorption (SSA) and blueshift. Moreover, the free-free absorption in the DCBH envelope may further reduce the signal in the SKA-low band. Thus, combining SKA-low and SKA-mid observations might provide a potential tool to distinguish a DCBH from a normal star-forming galaxy.

description: Topology in general but also topological objects such as monopoles are a central concept in physics. They are prime examples for the intriguing physics of gauge theories and topological states of matter. Vector monopoles are already frequently discussed such as the well-established Dirac monopole in three dimensions. Less known are tensor monopoles giving rise to tensor gauge fields. Here we report that tensor monopoles can potentially be realized in superconducting multi-terminal systems using the phase differences between superconductors as synthetic dimensions. In a first proposal we suggest a circuit of superconducting islands featuring charge states to realize a tensor monopole. As a second example we propose a triple dot system coupled to multiple superconductors that also gives rise to such a topological structure. All proposals can be implemented with current experimental means and the monopole readily be detected by measuring the quantum geometry.

description: We present a permanent magnet arrangement that can achieve a tuneable axial magnetic field from 1.80(8)-2.67(2) kG along the z-axis, where (x,y) = (0,0), with a rms field variation of less than 1% over a length of 25 mm. The instrument consists of an arrangement of off-the-shelf N42 neodymium-iron-boron (NdFeB) axially magnetized ring magnets, of varying outer and inner diameters. The magnets are organized into four cylindrical brass holders, whose relative separation can be manipulated to achieve the desired magnetic field strength and homogeneity over the region of interest. We present magnetic field computations and Marquardt-Levenberg fits to experimental data and demonstrate excellent agreement between theory and experiment. The apparatus has been designed to accommodate a cylindrical atomic vapor cell of length 25 mm and diameter 25 mm to lie within the bore of the ring magnets. The design has a clear aperture of 20 mm in the x-y plane along the z-axis, which opens up new avenues for imaging exploration in atomic spectroscopy.

description: Machine learning potentials (MLPs) trained on data from quantum-mechanics based first-principles methods can approach the accuracy of the reference method at a fraction of the computational cost. To facilitate efficient MLP-based molecular dynamics (MD) and Monte Carlo (MC) simulations, an integration of the MLPs with sampling software is needed. Here we develop two interfaces that link the Atomic Energy Network (ænet) MLP package with the popular sampling packages TINKER and LAMMPS. The three packages, ænet, TINKER, and LAMMPS, are free and open-source software that enable, in combination, accurate simulations of large and complex systems with low computational cost that scales linearly with the number of atoms. Scaling tests show that the parallel efficiency of the ænet-TINKER interface is nearly optimal but is limited to shared-memory systems. The ænet-LAMMPS interface achieves excellent parallel efficiency on highly parallel distributed memory systems and benefits from the highly optimized neighbor list implemented in LAMMPS. We demonstrate the utility of the two MLP interfaces for two relevant example applications, the investigation of diffusion phenomena in liquid water and the equilibration of nanostructured amorphous battery materials.

description: The clear separation of scales observed in halo nuclei between the extended halo and the compact core makes these exotic nuclei a perfect subject for Effective Field Theory (EFT). Such description leads to a systematic expansion of the core-halo Hamiltonian, which naturally orders the nuclear-structure observables. In this short review, I show the advantage there is to include Halo-EFT descriptions within precise models of reactions. It helps identifying the nuclear-structure observables that matter in the description of the reactions, and enables us to easily bridge predictions of nuclear-structure calculations to reaction observables. I illustrate this on breakup, transfer and knockout reactions with 11Be, the archetypical one-neutron halo nucleus.

description: We investigate single Ge and Ag impurities buried below a Cu(100) surface using low temperature scanning tunneling microscopy. The interference patterns in the local density of states are surface scattering signatures of the bulk impurities, which result from 3D Friedel oscillations and the electron focusing effect. Comparing the isoelectronic d scatterer Ag and the sp scatterer Ge allows to distinguish contributions from impurity scattering and the host. Energy-independent effective scattering phase shifts are extracted using a plane wave tight-binding model and reveal similar values for both species. A comparison with ab-initio calculations suggests incoherent sp scattering processes at the Ge impurity. As both scatterers are spectrally homogeneous, scanning tunneling spectroscopy of the interference patterns yields real-space signatures of the bulk electronic structure. We find a kink around zero bias for both species that we assign to a renormalization of the band structure due to many-body effects, which can be described with a Debye self-energy and a surprisingly high electron-phonon coupling parameter $λ$. We propose that this might originate from bulk propagation in the vicinity of the surface.

title: Axiomatizing One-Variable Fragments of First-Order Logics
Creators: name: Tokuda, Naomi
Publisher: name: Universität Bern

Subjects: subject: 510 Mathematics

description: First-order logics are much more expressive than their propositional counterparts, but often lack decidability. To remedy this problem while still maintaining some of the expressivity of first-order logics, we consider one-variable fragments of first-order logics. The one-variable fragment of a first-order logic consists of consequences in the logic constructed using one distinguished variable x, unary predicates, propositional operations, and the quantifiers (∀x) and (∃x). We define a semantics for a first-order logic based on a class of L-lattices, which induces a semantics for its one-variable fragment. However, finding an axiomatization of this fragment is generally not trivial. A Hilbert-style axiomatization of a first-order logic does not yield a Hilbert-style axiomatization of its one-variable fragment, since derivations of one-variable formulas may introduce new variables. Consequence in one-variable first-order logics can be translated into consequence in a class of algebras with modalities. Therefore, the challenge of finding axiomatizations for one-variable fragments may be interpreted as the challenge of finding an equational basis for the corresponding classes of algebras. Despite axiomatization results for certain fragments, a general approach has been missing. In this thesis, we take a first step towards overcoming this challenge, by proving that the class of algebras corresponding to the one-variable fragment of a first-order logic based on a variety of L-lattices that has the superamalgamation property admits an axiomatization by “S5-like” equations. This is achieved through both algebraic and proof-theoretic approaches.
Circumstellar Na I and Ca II lines in type IIP supernovae and SN 1998S

description: We study a possibility of detection of circumstellar absorption lines of Na I D$_{1,2}$ and Ca II H,K in spectra of type IIP supernovae at the photospheric epoch. The modelling shows that the circumstellar lines of Na I doublet will not be seen in type IIP supernovae for moderate wind density, e.g., characteristic of SN 1999em, whereas rather pronounced Ca II lines with P Cygni profile should be detectable. A similar model is used to describe Na I and Ca II circumstellar lines seen in SN 1998S, type IIL with a dense wind. We show that line intensities in this supernova are reproduced, if one assumes an ultraviolet excess, which is caused primarily by the comptonization of supernova radiation in the shock wave.

description: We discuss the lightest scalar resonances, $f_0(600)$, $κ(800)$, $a_0(980)$ and $f_0(980)$ in the extended Nambu Jona-Lasinio model. We find that the model parameters can be tuned, but unnaturally, to accommodate for those scalars except the $f_0(980)$. We also discuss problems encountered in the K Matrix unitarization approximation by using $N_c$ counting technique.

Building an interpretable fuzzy rule base from data using Orthogonal Least Squares Application to a depollution problem

description: In many fields where human understanding plays a crucial role, such as bioprocesses, the capacity of extracting knowledge from data is of critical importance. Within this framework, fuzzy learning methods, if properly used, can greatly help human experts. Amongst these methods, the aim of orthogonal transformations, which have been proven to be mathematically robust, is to build rules from a set of training data and to select the most important ones by linear regression or rank revealing techniques. The OLS algorithm is a good representative of those methods. However, it was originally designed so that it only cared about numerical performance. Thus, we propose some modifications of the original method to take interpretability into account. After recalling the original algorithm, this paper presents the changes made to the original method, then discusses some results obtained from benchmark problems. Finally, the algorithm is applied to a real-world fault detection depollution problem.

description: Galliumnitride has become a strategic superior material for space, defense and civil applications, primarily for power amplification at RF and mm-wave frequencies. For AlGaN/GaN high electron mobility transistors (HEMT), an outstanding performance combined together with low cost and high flexibility can be obtained using a System-in-a-Package (SIP) approach. Since thermal management is extremely important for these high power applications, a hybrid integration of the HEMT onto an AlN carrier substrate is proposed. In this study we investigate the temperature performance for AlGaN/GaN HEMTs integrated onto AlN using flip-chip mounting. Therefore, we use thermal simulations in combination with experimental results using micro-Raman spectroscopy and electrical dc-analysis.

A model of the joint determination of labor force participation and fertility decisions of married women
Creators: name: Mazany, Robin Leigh
Publisher: name: University of British Columbia
Year: 2010

description: In this dissertation, we examine the economic determinants of the labor force participation and fertility behavior of married women using a simultaneous equations model. The model takes into account both the truncation of hours of work at zero and the dichotomous nature of the decision of whether to have a child. We estimate the model using maximum likelihood methods. The data used are from the Michigan Panel Survey of Income Dynamics. We find the results from the simultaneous model to be quite different from the results obtained using single equation methods. Our results thus suggest a simultaneous framework is the most appropriate for the examination of labor force participation and fertility decisions. We run simulations on two different tax policies which might be expected to affect both the labor supply decision and the fertility decision. We find the tax policies do not have a large effect on either decision, although the effect on hours worked is stronger than the effect on fertility. We also find the effects of the policies to be stronger if there are already two children in the family.
Origin of Metallic States at Heterointerface between Band Insulators LaAlO$_3$ and SrTiO$_3$

description: We have studied the electronic structure at the heterointerface between the band insulators LaAlO$_3$ and SrTiO$_3$ using $in situ$ photoemission spectroscopy. Our experimental results clearly reveal the formation of a notched structure on the SrTiO$_3$ side due to band bending at the metallic LaAlO$_3$/TiO$_2$-SrTiO$_3$ interface. The structure, however, is absent at the insulating LaAlO$_3$/SrO-SrTiO$_3$ interface. The present results indicate that the metallic states originate not from the charge transfer through the interface on a short-range scale but from the accumulation of carriers on a long-range scale.

description: Baryonic matter can be accreted on to primordial back holes (PBHs) formed in the early Universe. The radiation from accreting PBHs is capable of altering the evolution of the intergalactic medium (IGM), leaving marks on the global 21 cm signal in the dark ages. For accreting PBHs with mass $M_{\rm PBH}=10^{3}(10^{4})~M_{\odot}$ and mass fraction $f_{\rm PBH}=10^{-1}(10^{-3})$, the brightness temperature deviation $ΔδT_{b}$ reaches $\sim 18~(26)~\rm mK$ at redshift $z\sim 90$ ($ν\sim 16~\rm MHz$), and the gradient of the brightness temperature $dδT_{b}/dν$ reaches $ \sim 0.8~(0.5)~\rm mK~MHz^{-1}$ at frequency $ν\sim 28~\rm MHz$ ($z\sim 50$). For larger PBHs with higher mass fraction, the brightness temperature deviation is larger in the redshift range $z\sim 30-300$ ($ν\sim 5-46~\rm MHz$), and the gradient is lower at the frequency range $ν\sim 20-60~\rm MHz$ ($z\sim 23-70$). It is impossible to detect these low frequency radio signals from the Earth due to the influence of the Earth's ionosphere. However, after taking care of the essential factors properly, e.g. the foreground and interference, future radio telescope in lunar orbit or on the farside surface of the Moon has a chance of detecting the global 21 cm signals impacted by accreting PBHs and distinguishing them from the standard model.
