description: We present a far-ultraviolet (FUV) study of the globular cluster M30 (NGC 7099). The images were obtained using the Advanced Camera for Surveys (ACS/SBC, F150LP, FUV) and the Wide Field Planetary Camera 2 (WFPC2, F300W, UV) which were both on board the Hubble Space Telescope (HST). The FUV-UV colour-magnitude diagram (CMD) shows a main sequence (MS) turnoff at FUV $\approx$ 22 mag and FUV-UV $\approx$ 3 mag. The MS extends 4 mag below the turnoff, and a prominent horizontal branch (HB) and blue straggler (BS) sequence can be seen. A total of 1218 MS stars, 185 red giant branch stars, 47 BS stars and 41 HB stars are identified, along with 78 sources blueward of the MS which consist of white dwarfs (WDs) and objects in the gap between the WDs and the MS that include potential cataclysmic variable (CV) candidates. The radial distribution of the BS population is concentrated towards the cluster centre, indicating that mass segregation has occurred. The blue and red sub-populations of the double BS sequence appear mixed in the ultraviolet CMD, and no significant central concentration of CV candidates is seen in this cluster.

description: Our aim is to test the accretion scenario of lambda Boo stars. This model predicts that a binary system with two early-type stars passing through a diffuse cloud should both display the same superficial peculiarity. We carried out a detailed abundance determination of three multiple systems hosting a candidate lambda Boo star: the remarkable triple system HD 15164/65/65C and the binary systems HD 193256/281 and HD 198160/161. The abundance analysis of HD 15164/65/65C shows a clear lambda Boo object (HD 15165) and two objects with near solar composition (HD 15164 and 15165C). Notably, the presence of a lambda Boo star (HD 15165) together with a near solar early-type object (HD 15164) is difficult to explain under the accretion scenario. Also, the solar-like composition derived for the late-type star of the system (HD 15165C) could be used, for the first time, as a proxy for the initial composition of the lambda Boo stars. Then, by reviewing abundance analysis of all known binary systems with candidate lambda Boo stars from literature and including the systems analyzed here, we find no binary/multiple system having two clear "bonafide" lambda Boo stars, as expected from the accretion scenario. The closer candidates to show two lambda Boo-like stars are HD 84948, HD 171948 and HD 198160; however, in our opinion they show mild rather than clear lambda Boo patterns. Our results brings little support to the accretion scenario. Then, there is an urgent need of additional binary and multiple systemsto be analyzed through a detailed abundance analysis.[abridged]

description: Nuclear matter properties based on a relativistic approach suitable for the description of multi-component systems are calculated. We use a set of nuclear relativistic mean-field models that satisfy acceptable nuclear matter properties and neutron star observations. The effects of the density dependence of the symmetry energy and of the Landau quantization due to the presence of a strong external magnetic field are discussed. Properties such as the proton fraction, the Landau mass, Landau parameters and entrainment matrix, the adiabatic index and speed of sound are calculated for cold $β$-equilibrium matter. A large dispersion on the calculated properties is obtained at two to three times saturation density $ρ_0 $. The proton Landau mass can be as low as one third of the vacuum nucleon mass at 2-3$~ρ_0 $. Similar effects are obtained for the Landau parameters, in particular, the ones involving protons, where the relative dispersion of $F^0_{pp}$ and $F^1_{pp}$ is as high as 30\% to 50\% at 2-3$~ρ_0 $. These parameters are particularly sensitive to the symmetry energy. The effect of the magnetic field on the nuclear properties is small for fields as high as 10$^{18}$G except for a small range of densities just above the crust-core transition. Tables with the EoS, and the parameters, are provided in the Supplementary Material section.

description: Four families' experiences in an educational cooperative and the impact on their home schools are detailed in the study. Results indicated that the families were highly dependent upon the cooperative. The cooperative signified a compromise for the families between the freedom of home schooling and the accountability and support provided by a school. These findings are important for traditional education. Just as home schools are evolving and developing institutions that look something like schools, schools can change too. One way is for the traditional school to operate as a family and community resource rather than the sole purveyor of knowledge.

title: An assessment of the criminal law’s protection of privacy and reputation rights
Creators: name: Reid, Robbie George
Publisher: name: University of Glasgow
Year: 2025

description: This thesis seeks to provide a critical assessment of the criminal law’s protection of two fundamental interests: privacy and reputation. While protection of these interests is traditionally rooted in the civil law and there has been considerable scholarship in this context, the extent to which the criminal law upholds and protects these interests remains under-researched. This is particularly so in Scotland, where much of the criminal law continues to be part of the common law and has developed from historical principles and precedents.

This is an appropriate time at which to carry out this research. Privacy and reputation interests have become increasingly valuable and are recognised as fundamental rights, receiving protected status in international human rights instruments. These interests have nevertheless become more vulnerable to harmful conduct and subject to greater levels of interference. Technological advancements, the growth of social media, and the collection and retention of personal data all pose significant threats to privacy and reputation.

These developments have been accompanied by some legislative intervention in Scots law (e.g. the introduction of offences combatting stalking, the non-consensual distribution of intimate images, stirring up hatred). While these offences may have some bearing on privacy and reputation, there has been no principled consideration of how these interests arespecifically protected (nor how they ought to be protected) by the criminal law. Moreover, despite recent reform of defamation law in Scotland resulting in the introduction of the Defamation and Malicious Publication (Scotland) Act 2021, this did not take account of the role that may be played by the criminal law.

This research seeks to address these shortcomings by establishing a normative basis for protecting these interests through the criminal law. It argues that there is scope for the criminal law to play a greater role in regulating violations of three interests: informational privacy, physical privacy, and reputation. This argument is developed, firstly, by reference to fundamental criminalisation principles (wrongfulness, harmfulness and culpability) and, secondly, the impact that this may have in terms of conveying the seriousness of such wrongsand facilitating practical improvements for victims of privacy and reputation violations.It is concluded that this would overcome some of the existing limitations in the legal mechanisms through which these rights are protected, as identified through a detailed evaluation of relevant criminal and civil wrongs undertaken in this thesis.

description: Measurements of the $^2$H($^{16}$C,$^{16}$C$^{*}$$\rightarrow^4$He+$^{12}$Be or $^6$He+$^{10}$Be)$^2$H inelastic excitation and cluster-decay reactions have been carried out at a beam energy of about 23.5 MeV/u. A specially designed detection system, including one multi-layer silicon-strip telescope at around zero degrees, has allowed the high-efficiency three-fold coincident detection and therefore the event-by-event determination of the energy of the unstable nucleus beam. The decay paths from the $^{16}$C resonances to various states of the final $^{10}$Be or $^{12}$Be nucleus are recognized thanks to the well-resolved $Q$-value spectra. The reconstructed resonances at 16.5(1), 17.3(2), 19.4(1) and 21.6(2) MeV are assigned as the $0^+$, $2^+$, $4^+$ and $6^+$ members, respectively, of the positive-parity $(3/2_π^-)^2(1/2_σ^-)^2$-bond linear-chain molecular band in $^{16}$C, based on the angular correlation analysis for the 16.5 MeV state and the excellent agreement of decay patterns between the measurements and theoretical predictions. Moreover, another intriguing high-lying state was observed at 27.2(1) MeV which decays almost exclusively to the $\sim$6 MeV states of $^{10}$Be, in line with the newly predicted pure $σ$-bond linear-chain configuration.

description: Observed changes in protostellar brightness can be complicated to interpret. In our JCMT~Transient monitoring survey, we discovered that a young binary protostar, HOPS 373, is undergoing a modest $30\%$ brightness increase at 850 $μ$m, caused by a factor of 1.8$-$3.3 enhancement in the accretion rate. The initial burst occurred over a few months, with a sharp rise and then shallower decay. A second rise occurred soon after the decay, and the source is still bright one year later. The mid-IR emission, the small-scale CO outflow mapped with ALMA, and the location of variable maser emission indicate that the variability is associated with the SW component. The near-infrared and NEOWISE $W1$ and $W2$ emission is located along the blueshifted CO outflow, spatially offset by $\sim3$ to $4^{\prime\prime}$ from the SW component. The $K$-band emission imaged by UKIRT shows a compact H$_2$ emission source at the edge of the outflow, with a tail tracing the outflow back to the source. The $W1$ emission, likely dominated by scattered light, brightens by 0.7 mag, consistent with expectations based on the sub-mm lightcurve. The signal of continuum variability in $K$-band and $W2$ is masked by stable H$_2$ emission, as seen in our Gemini/GNIRS spectrum, and perhaps by CO emission. These differences in emission sources complicate infrared searches for variability of the youngest protostars.

description: This study examined the day to day operations of home schools. The case study method was used with four families from a larger pool of families that held membership in a home school organization. Data was gathered using interviews, observations, and artifacts. Findings suggest that these families operated their home schools using traditional methods to reach progressive goals. The families operated their home schools much as a person in a restaurant would choose food from a menu. They identified instructional goals and selected methods from a variety of choices available to them including courses taught through a home school cooperative, community colleges, online courses, video instruction, and individual study. Public schooling was not an option available to them. Traditional schools can learn from this home school model as it serves as a resource that supports individual learning goals rather than as the sole distributor of knowledge in a community.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.

description: We present a catalog of 97 uniformly-vetted candidates for quadruple star systems. The candidates were identified in TESS Full Frame Image data from Sectors 1 through 42 through a combination of machine learning techniques and visual examination, with major contributions from a dedicated group of citizen scientists. All targets exhibit two sets of eclipses with two different periods, both of which pass photocenter tests confirming that the eclipses are on-target. This catalog outlines the statistical properties of the sample, nearly doubles the number of known multiply-eclipsing quadruple systems, and provides the basis for detailed future studies of individual systems. Several important discoveries have already resulted from this effort, including the first sextuply-eclipsing sextuple stellar system and the first transiting circumbinary planet detected from one sector of TESS data.

description: Intermediate- and high-velocity clouds (IVCs, HVCs) are a potential source of fuel for star formation in the Milky Way (MW), but their origins and fates depend sensitively on their distances. We search for IVC and HVC in HST high-resolution ultraviolet spectra of 55 halo stars at vertical heights $|z| \gtrsim 1$ kpc. We show that IVCs ($40 \leq |v_{\rm LSR}| <90$ km/s) have a high detection rate - the covering factor, $f_c$ - that is about constant ($f_c =0.90\pm 0.04$) from $z=1.5$ to $14$ kpc, implying IVCs are essentially confined to $|z|\lesssim 1.5$ kpc. For the HVCs ($90 \leq |v_{\rm LSR}| \lesssim 170$ km/s), we find $f_c$ increases from $f_c \simeq 0.14\pm 0.10$ at $|z|\lesssim 2-3$ kpc to $f_c =0.60\pm 0.15$ at $5\lesssim |z|\lesssim 14$ kpc, the latter value being similar to that found towards QSOs. In contrast, the covering factor of very high-velocity clouds (VHVCs, $|v_{\rm LSR}|\gtrsim 170$ km/s) is $f_c<4\%$ in the stellar sample compared to 20\% in a QSO sample, implying these clouds must be at $d\gtrsim 10-15$ kpc ($|z|\gtrsim 10$ kpc). Gas clouds with $|v_{\rm LSR}|>40$ km/s at $|b|\gtrsim 15^\circ$ have therefore $|v_{\rm LSR}|$ decreasing with decreasing $|z|$. Assuming each feature originates from a single cloud, we derive scale-heights of $1.0 \pm 0.3$ and $2.8 \pm 0.3$ kpc for the IVCs and HVCs, respectively. Our findings provide support to the "rain" and galactic fountain models. In the latter scenario, VHVCs may mostly serve as fuel for the MW halo. In view of their locations and high covering factors, IVCs and HVCs are good candidates to sustain star formation in the MW.

description: We present the first Chandra detection of a single X-ray cavity within the interstellar medium of the small Fanaroff-Riley type I (FRI) radio galaxy NGC 5141. The X-ray surface brightness depression, located $\approx 4$ kpc away from the galaxy center, is projected on the northern radio lobe, which is completely contained within the galaxy. The thermal gas surrounding the cavity, which extends to $\approx$ 20 kpc, has a bolometric X-ray luminosity (0.1 - 100 keV) of L${_X}\approx2\times10^{40}$ erg s$^{-1}$ and a temperature of $kT\approx0.8$ keV. We calculated the total energy (E$_{cav} = 4PV \approx 10^{55}$ erg) required to inflate the cavity and its age ($t_{cav}\approx 9$ Myrs), assuming that it is filled with relativistic particles and rises buoyantly. The inferred total cavity power is as low as P$_{cav}=E_{cav}/t_{cav}\approx6\times10^{40}$ erg s$^{-1}$, which is the lowest one among the radio-filled systems. Comparing $P_{cav}$ to the bolometric X-ray luminosity (i.e., the cooling luminosity), we conclude that NGC 5141's central active galactic nucleus can heat the interstellar medium and balance its cooling luminosity, confirming that the $P_{cav}-L_{cool}$ relation, mainly tested on groups and clusters, also works for such a low-power system.

description: The hyperfine interaction between the spins of electrons and nuclei is both a blessing and a curse. It can provide a wealth of information when used as an experimental probing technique but it can also be destructive when it acts as a dephasive perturbation on the electronic system. In this work, we fabricated large scale single and multilayer isotopically-purified $^{13}$C graphene Hall bars to search for interaction effects between the nuclear magnetic moments and the electronic system. We find signatures of nuclei with a spin in the analysis of the weak localization phenomenon that shows a significant dichotomy in the scattering times of monolayer $^{12}$C and $^{13}$C graphene close the Dirac point. Microwave-induced electron spin flips were exploited to transfer momentum to the nuclei and build-up a nuclear field. The presence of a very weak nuclear field is encoded in a modulation of the electron Zeeman energy which shifts the energy for resonant absorption and reduces the $g$-factor.

description: The adoption of Common Core State Standards presents the social studies with an opportunity and a challenge. Common Core State Standards focus on college and career readiness. The focus on college and career readiness is a challenge because the civic education goal of social studies may be lost or overlooked. The opportunity is that social studies is one of those other areas that must be used to help develop literacy. The goal of this paper is to discuss how to use social studies texts, specifically primary sources related to Susan B. Anthony’s trial, to meet literacy and social studies goals.

They have stable predictions for observables, such as $n_s=1-{2/ N_e} $, assuming that the potential in terms of the original geometric variables, as well as its derivatives, are not singular at the boundary of the hyperbolic disk, or half-plane. In these models, the potential in the canonically normalized inflaton field $φ$ has a plateau, which is approached exponentially fast at large $φ$. We call them exponential $α$-attractors. We present a closely related class of models, where the potential is not singular, but its derivative is singular at the boundary. The resulting inflaton potential is also a plateau potential, but it approaches the plateau polynomially. We call them polynomial $α$-attractors. Predictions of these two families of attractors completely cover the sweet spot of the Planck/BICEP/Keck data. The exponential ones are on the left, the polynomial are on the right.

description: The question whether the interaction of a circumbinary disc with the central binary system leads to shrinking or expansion of the binary orbit has attracted considerable interest as it impacts the evolution of binary black holes and stellar binary stars in their formation phase. We performed two-dimensional hydrodynamical simulations of circumbinary discs for a large parameter set of disc viscosities and thicknesses and two different binary mass ratios for binaries on circular orbits. For those we measured carefully the net angular momentum and mass transfer between disc and binary system, and evaluate the normalised specific angular momentum accretion, $j_\mathrm{s}$ . This is compared to the theoretical, critical specific angular momentum change $j_\mathrm{s,crit}$ that separates contracting from expanding cases which depends on the the binary's mass ratio and the relative accretion onto the two stars. Using finite and infinite disc models we show that the inferred binary evolution is very similar for both setups and confirm that $j_\mathrm{s}$ can be measured accurately with cylindrical simulations that do not include the central binary. However, to obtain the relative accretion onto the stars for non-equal mass binaries, simulations that cover the whole domain including the binary are required. We find that for thick discs with aspect ratio $h = 0.1$ the binaries expand for all viscosities, while discs with $h = 0.05$ lead to an expansion only for larger viscosities with $α$ exceeding $\sim 0.005$. Overall, the regime of binary expansion extends to a much wider parameter space than previously anticipated, but for thin, low viscosity discs the orbits shrink.

description: Objective: To compare speech reception thresholds (SRTs) in noise using matrix sentence tests in four languages: German, Spanish, Russian, Polish. Design: The four tests were composed of equivalent five-word sentences and were all designed and optimized using the same principles. Six stationary speech-shaped noises and three non-stationary noises were used as maskers. Study sample: Forty native listeners with normal hearing: 10 for each language. Results: SRTs were about 3 dB higher for the German and Spanish tests than for the Russian and Polish tests when stationary noise was used that matched the long-term frequency spectrum of the respective speech test materials. This general SRT difference was also observed for the other stationary noises. The within-test variability across noise conditions differed between languages. About 56% of the observed variance was predicted by the speech intelligibility index. The observed SRT benefit in fluctuating noise was similar for all tests, with a slightly smaller benefit for the Spanish test. Conclusions: Of the stationary noises employed, noise with the same spectrum as the speech yielded the best masking. SRT differences across languages and noises could be attributed in part to spectral differences. These findings provide the feasibility and limits of comparing audiological results across languages.

description: This study examined the motivations of families that operate home schools. Four intact, religiously conservative families were interviewed and observed over one year. Findings showed that families were motivated by multiple factors to leave traditional schooling and begin home schooling. Additionally, the motivations to home school influenced the families‘ instructional practices. Finally, results indicated that the decision to home school was a positive decision for the families, not an outright rejection of traditional schooling. This study reveals the complex motivations to home school and may assist administrators, teachers, and policymakers in traditional schools induct and retain families considering home schooling.
Needles in a haystack: An algorithmic approach to the classification of 4d $\mathcal{N}=2$ SCFTs

description: There is a well-known map from 4d $\mathcal{N}=2$ superconformal field theories (SCFTs) to 2d vertex operator algebras (VOAs). The 4d Schur index corresponds to the VOA vacuum character, and must be a solution with integral coefficients of a modular differential equation. This suggests a classification program for 4d $\mathcal{N}=2$ SCFTs that starts with modular differential equations and proceeds by imposing all known constraints that follow from the 4d $\to$ 2d map. This program becomes fully algorithmic once one specifies the $\mathrm{\textit{order}}$ of the modular differential equation and the $\mathrm{\textit{rank}}$ (complex dimension of the Coulomb branch) of the $\mathcal{N}=2$ theory. As a proof of concept, we apply the algorithm to the study of rank-two $\mathcal{N}=2$ SCFTs whose Schur indices satisfy a fourth-order untwisted modular differential equation. Scanning over a large number of putative cases, only 15 satisfy all of the constraints imposed by our algorithm, six of which correspond to known 4d SCFTs. More sophisticated constraints can be used to argue against the existence of the remaining nine cases. Altogether, this indicates that our knowledge of such rank-two SCFTs is surprisingly complete.

description: We present CO(1--0) observations of the high-redshift quasar SDSS J160705+533558 ($z=3.653$) using the Karl G. Jansky Very Large Array (VLA). We detect CO emission associated with the quasar and at $\sim16.8\,\rm kpc$ projected distance from it, separated by $\sim800\,\rm km\,s^{-1}$ in velocity. The total molecular gas mass of this system is $\sim5\times10^{10}\,\rm M_{\odot}$. By comparing our CO detections with previous submillimetre (submm) observations of the source, an offset between the different emission components is revealed: the peak of the submm emission is offset from the quasar and from the CO companion detected in our VLA data. To explain our findings, we propose a scenario similar to that for the Antennae galaxies: SDSS J160705+533558 might be a merger system in which the quasar and the CO companion are the merging galaxies, whose interaction resulted in the formation of a dusty, star-forming overlap region between the galaxies that is dominant at the submm wavelengths.

description: Detection of bending waves is a highly challenging task even in nearby disc galaxies due to their sub-kpc bending amplitudes. However, simulations show that the harmonic bending of a Milky Way like disc galaxy is associated with a harmonic fluctuation in the measured line of sight (los) velocities as well, and can be regarded as a kinematic signature of a manifested bending wave. Here, we look for similar kinematic signatures of bending waves in \HI discs, as they extend to much beyond the optical radii. We present a multipole analysis of the \HI los residual velocity fields of six nearby spiral galaxies from the THINGS sample, which uncovers the bending wave-induced velocity peaks. This allows us to identify the radial positions and amplitudes of the different bending modes present in the galaxies. We find that all of our sample discs show a combined kinematic signature of superposition of a few lower-order bending modes, suggesting that bending waves are a common phenomenon. The identified velocity peaks are found to be of modes $m=2,3$ and $4$, not more than 15 km s$^{-1}$ in amplitude and spread across the entire \HI disc. Interestingly, they appear to be concentrated near the optical edge of their host galaxies. Also, $m=2$ appears to be more common than the other two modes.

description: Aims. The first relativistic solar proton event of solar cycle 25 (SC25) was detected on 28 October 2021 by neutron monitors (NMs) on the ground and particle detectors onboard spacecraft in the near-Earth space. This is the first ground level enhancement (GLE) of the current cycle. A detailed reconstruction of the NM response together with the identification of the solar eruption that generated these particles is investigated based on in-situ and remote-sensing measurements. Methods. In-situ proton observations from a few MeV to $\sim$500 MeV were combined with the detection of a solar flare in soft X-rays (SXRs), a coronal mass ejection (CME), radio bursts and extreme ultraviolet (EUV) observations to identify the solar origin of the GLE. Timing analysis was performed and a relation to the solar sources was outlined. Results. GLE73 reached a maximum particle rigidity of $\sim$2.4 GV and is associated with type III, type II, type IV radio bursts and an EUV wave. A diversity of time profiles recorded by NMs was observed. This points to an anisotropic nature of the event. The peak flux at E$>$10 MeV was only $\sim$30 pfu and remained at this level for several days. The release time of $\geq$1 GV particles was found to be $\sim$15:40 UT. GLE73 had a moderately hard rigidity spectrum at very high energies ($γ$ $\sim$5.5). Comparison of GLE73 to previous GLEs with similar solar drivers is performed

description: This study examined the perspectives of home school families regarding the rights, interests, and responsibilities of family and state over education. These families viewed the common good differently than critics of home schooling. They believed the diversity of curriculum and worldview in their home schools positively impacts the common good by increasing the overall diversity of society. These families situated the practice of home schooling within the exercise of religion inserting a Constitutional challenge into the debate over home schooling. The voices of these families, their declarations of independence from the educational norm in our nation, challenge our views of what really is the common good, what diversity we value, and what activities we include in our definition of the free exercise of religion.

description: DNA barcoding has been proposed as a method for species identification. However, this method has been criticised for its over-reliance on a single mitochondrial gene. In this study, four mitochondrial gene regions and one nuclear gene region were used to investigate their different abilities to identify tissue associated with museum specimens of Aethomys chrysophilus, Aethomys ineptus and Micaelamys namaquensis. Aethomys chrysophilus and the more recently elevated A. ineptus are indistinguishable on morphological grounds; however, their ranges are largely parapatric with only one syntopic locality currently known. All of the mitochondrial gene regions were able to separate M. namaquensis from A. chrysophilus and A. ineptus, but they varied in their abilities to resolve differences between A. chrysophilus and A. ineptus. The sequence results identified a specimen from KwaZulu-Natal that was misclassified and should have been identified as A. ineptus. Seven specimens that had not been reclassified following the elevation of A. ineptus to species level were identified as A. ineptus. Individuals of A. chrysophilus from Malawi could not be classified as either A. chrysophilus or A. ineptus, and may be a hybrid or a new, distinct species. This study indicates that DNA barcoding may be used to separate M. namaquensis from A. chrysophilus and A. ineptus, and although it was not able to separate A. chrysophilus and A. ineptus, it did indicate specimens from Malawi may be a new cryptic species.
