Agama anchietae Bocage, 1896
MATERIAL.— INP, 29 November 2013, 16º39ʹ27.12ʺS, 12º26ʹ17.04ʺE, 459 m (CAS 254778); Pico Azevedo, 7 December 2013, 15º32ʹ2.4ʺS, 12º29ʹ31.1ʺE, 359 m (CAS 254942); NNP, 28 November 2013, 15º46ʹ27.4ʺS. 12º19ʹ59.2ʺE, 264 m (CAS 254956).
COMMENTS.— These specimens have distinctive black-tipped spines on the palmar scales, which distinguish A. anchietae from the morphologically similar A. aculeata Merrem, 1820 that occurs sympatrically in Southern Angola and Namibia (Branch 1993). Agama anchietae was described from Angola by Bocage based on specimens from Catumbela, Benguela and Dombe (all in Benguela Province), and Moçamedes (currently Namibe, Namibe Province). In Angola, the species is known to occur in Namibe Province (Bocage 1896, 1897; Laurent 1964a), Benguela Province (Bocage 1863, 1896, 1897), and Bié Province (Schmidt 1933). Our specimens represent the southernmost localities of the species in Angola, although it is certainly distributed continuously across the entire province.

description: Crystalline $\rm Bi_2Se_3$ is one of the most explored three-dimensional topological insulator, with a $0.3\;\rm eV$ energy gap making it promising for applications. Its amorphous counterpart could bring to light new possibilities for large scale synthesis and applications. Using ab initio molecular dynamics simulations, we have studied realistic amorphous $\rm Bi_2Se_3$ phases generated by different processes of melting, quenching, and annealing. Extensive structural and electronic characterizations show that the melting process induces an energy gap decrease ruled by growth of the defective local environments. This behavior dictates a weak stability of the topological phase to disorder, characterized by the spin Bott index. Interestingly, we identify the occurrence of topologically trivial surface states in amorphous $\rm Bi_2Se_3$ that show a strong resemblance with standard helical topological states. Our results and methods advance the search of topological phases in three-dimensional amorphous solids.
Non-parametric machine learning for biological sequence data
Creators: name: Ish-Horowicz, Jonathan
Publisher: name: Imperial College London
Year: 2022

description: In the past decade there has been a massive increase in the volume of biological sequence data, driven by massively parallel sequencing technologies. This has enabled data-driven statistical analyses using non-parametric predictive models (including those from machine learning) to complement more traditional, hypothesis-driven approaches. This thesis addresses several challenges that arise when applying non-parametric predictive models to biological sequence data. Some of these challenges arise due to the nature of the biological system of interest. For example, in the study of the human microbiome the phylogenetic relationships between microorganisms are often ignored in statistical analyses. This thesis outlines a novel approach to modelling phylogenetic similarity using string kernels and demonstrates its utility in the two-sample test and host-trait prediction. Other challenges arise from limitations in our understanding of the models themselves. For example, calculating variable importance (a key task in biomedical applications) is not possible for many models. This thesis describes a novel extension of an existing approach to compute importance scores for grouped variables in a Bayesian neural network. It also explores the behaviour of random forest classifiers when applied to microbial datasets, with a focus on the robustness of the biological findings under different modelling assumptions.

description: Context. Relativistic jets are ubiquitous in astrophysics. High Mass Microquasars (HMMQs) are useful labs to study such jets, as they are relatively close and evolve over observable time scales. The ambient medium into which the jet propagates is, however, far from homogeneous. Corresponding simulation studies to date consider various forms of a wind-shaped ambient medium but typically neglect radiative cooling and relativistic effects. Aims. We investigate the dynamical and structural effects of radiative losses and system parameters on relativistic jets in HMMQs, from the jet launch to its propagation over several tens of orbital separations. Methods. We use 3D relativistic hydrodynamical simulations including parameterized radiative cooling derived from relativistic thermal plasma distribution to carry out parameter studies around two fiducial cases inspired by Cygnus X-1 and Cygnus X-3. Results. Radiative losses are found to be more relevant in Cygnus X-3 than Cygnus X-1. Varying jet power, jet temperature, or the wind of the donor star tends to have a larger impact at early times, when the jet forms and instabilities initially develop, than at later times when the jet has reached a turbulent state. Conclusions. Radiative losses may be dynamically and structurally relevant at least in Cygnus X-3 case, and thus should be examined in more detail.

description: We introduce a new class of natural, explicitly defined, transversally elliptic differential operators over manifolds with compact group actions. Under certain assumptions, the symbols of these operators generate all the possible values of the equivariant index. We also show that the components of the representation-valued equivariant index coincide with those of an elliptic operator constructed from the original data.

description: For the description of an H2 molecule an effective one-electron model potential is proposed which is fully determined by the exact ionization potential of the H2 molecule. In order to test the model potential and examine its properties it is employed to determine excitation energies, transition moments, and oscillator strengths in a range of the internuclear distances, 0.8 < R < 2.5 a.u. In addition, it is used as a description of an H2 target in calculations of the cross sections for photoionization and for partial excitation in collisions with singly-charged ions. The comparison of the results obtained with the model potential with literature data for H2 molecules yields a good agreement and encourages therefore an extended usage of the potential in various other applications or in order to consider the importance of two-electron and anisotropy effects.

description: We have studied analytically the longitudinally boost-invariant motion of a relativistic dissipative fluid with spin. We have derived the analytic solutions of spin density and spin chemical potential as a function of proper time $τ$ in the presence of viscous tensor and the second order relaxation time corrections for spin. Interestingly, analogous to the ordinary particle number density and chemical potential, we find that the spin density and spin chemical potential decay as $\simτ^{-1}$ and $\simτ^{-1/3}$, respectively. It implies that the initial spin density may not survive at the freezeout hyper-surface. These solutions can serve both to gain insight on the dynamics of spin polarization in relativistic heavy-ion collisions and as testbeds for further numerical codes.

description: In Italy in the 60s and 70s, poetry and the very image of poets underwent a radical metamorphosis. The body of the poet becomes fully visible for the first time thanks to new media (photography, cinema, television) and their mass diffusion, while the poetic experience allows closed literary circles to open themselves to other arts in search of a new intertextual dimension. The transformation of the poet into a performer is part of a widespread trend to dissolve the borders between various media, traditions, and contexts. Poetry – like the visual arts, theater, music, dance, etc. – is featured in art magazines and performed in public places, as well as in cinema and on television screens. The essay examines this transformation in a series of exemplary cases where the body of the poet becomes the object of the attention of other artists: Giuseppe Ungaretti and Pier Paolo Pasolini in Comizi d’amore (1964), Mario Schifano and Sandro Penna in the experimental film Umano non umano (1969), Pasolini again in a performance by Fabio Mauri (Intellettuale, 1975), and Dino Pedrali’s intimate series of photographs shot just two days before Pasolini’s death in 1975.

description: The spacetime surrounding compact objects such as neutron stars and black holes provides an excellent place to study gravity in the strong, non-linear, dynamical regime. Here, the effects of strong curvature can leave their imprint on observables which we may use to study gravity. Recently, NICER provided a mass and radius measurement of an isolated neutron star using x-rays, while LIGO/Virgo measured the tidal deformability of neutron stars through gravitational waves. These measurements can be used to test the relation between the tidal deformability and compactness of neutron stars that are known to be universal in general relativity. Here, we take (shift-symmetric) scalar-Gauss-Bonnet gravity (motivated by a low-energy effective theory of a string theory) as an example and study whether one can apply the NICER and LIGO/Virgo measurements to the universal relation to test the theory. To do so, this paper is mostly devoted on theoretically constructing tidally-deformed neutron star solutions in this theory perturbatively and calculate the tidal deformability for the first time. We find that the relation between the tidal deformability and compactness remains to be mostly universal for a fixed dimensionless coupling constant of the theory though the relation is different from the one in general relativity. We also present a universal relation between the tidal deformability \textbf{of} one neutron star and the compactness for another neutron star that can be directly applied to observations by LIGO/Virgo and NICER. For the equations of state considered in this paper, it is still inconclusive whether one can place a meaningful bounds on scalar Gauss-Bonnet gravity with the new universal relations. However, we found a new bound from the mass measurement of the pulsar J0740+6620 that is comparable to other existing bounds from black hole observations.

COMMENTS.— Only four records of this species are known for the country: Ongueria, 55 km from Sá da Bandeira (presently Lubango), in Huíla Province (Laurent 1964a), Praia das Conchas (Laurent 1964a), “around Moçâmedes in the road to Sá da Bandeira” (Laurent 1964a) and Pico Azevedo (Schmidt 1933), both in Namibe Province. Our records represent southern range extensions for the species in the country, although the species extends into west-central Namibia (Bauer et al. 1993). In both Namibia and Angola it can occur sympatrically with other, similarly sized congeners, but is generally more restricted to rocky habitats than either C. pulitzerae or C. turneri.

description: We present a new abundance analysis of HE 1327-2326, the currently most iron-poor star, based on observational data obtained with VLT/UVES. We correct the 1D LTE abundances for 3D effects to provide an abundance pattern that supersedes previous works, and should be used to observationally test current models of the chemical yields of the first-generation SNe. Apart from confirming the 1D LTE abundances found in previous studies before accounting for 3D effects, we make use of a novel technique to apply the 3D-1D corrections for CNO which are a function of excitation potential and line strength for the molecular lines that comprise the observable CH, NH, and OH features. We find that the fit to the NH band at 3360 A is greatly improved due to the application of the 3D-1D corrections. This may indicate that 3D effects are actually observable in this star. We also report the first detection of several weak Ni lines. The cosmologically important element Li is still not detected; the new Li upper limit is extremely low, A(Li)<0.62, and in stark contrast with results not only from WMAP but also from other metal-poor stars. We also discuss how the new corrected abundance pattern of HE 1327-2326 is being reproduced by individual and integrated yields of SNe.

An examination of the adaptive significance of interpopulation variation in the behaviour of the guppy Poecilia reticulata
Creators: name: Luyten, Peter Henri
Publisher: name: University of British Columbia
Year: 2010

description: Populations of guppies (Poecilia reticulata) are found in rivers in Trinidad which differ in biotic and abiotic characteristics. Guppies from these rivers differ in a number of behavioural and morphological characteristics. Guppies in a turbid lowland river were found to be more cohesive and inhabit areas closer to shore than fish in clear headstream rivers. Males in the turbid lowland river exhibited a greater frequency of thrusts in their courtship than did males in the headstream rivers. Conversely, headstream males exhibited a greater frequency and duration of sigmoid displays in their courtship than did lowland males. These differences in courtship behaviour between males in headstream and lowland rivers persisted in males bred in the laboratory under identical conditions. This strongly suggests that the differences in behaviour are at least in part genetically determined, and that therefore the behaviours are a product of natural selection. Five experiments were designed in order to test the hypothesis that the identified differences in courtship behaviour exhibited by the populations are adaptations, in part, to differences in the turbidity of the rivers in which the populations naturally occur. If they are adaptations, they will contribute to the mating success of males in their particular environments. Males from turbid and clear rivers were placed in competition for mating with females under both clear and turbid water conditions. Mating success was determined on the basis of number of inseminations and sperm contributed to females by males of the different populations. Sperm where identified using a radioactive labelling technique and standard autoradiographic methods. In clear water, male guppies from a clear headstream river were more successful at mating with their own females and as successful at mating with lowland females as males from a turbid lowland river. In turbid water, males from the turbid lowland river were more successful at mating with their own females and equally successful at mating with headstream females as males from the clear headstream river. These results are consistent with the hypothesis that a high frequency of display and displays of long duration in male courtship are adaptations to clear water conditions. The results are also consistent with the hypothesis that high frequencies of thrusts in male courtship is an adaptation to turbid water conditions. Males exhibiting similar courtship behaviours from two geographically isolated headstream rivers were significantly more successful at mating with females from their own populations. This suggests that other factors, such as colour or pheromones, may also be important in determining mating success.

COMMENTS.— This species occurs from the southern regions of Angola in Namibe (Bocage 1867, 1887, 1895; Laurent 1964a; Schmidt 1933) and Cunene (Monard 1937) provinces to Malange, where it reaches its northern distribution in Capanda (Ceríaco et al. 2014). There are records from the far northwest of Namibia as well, although these have been consistently treated as either C. turneri or C. laevigatus. This species was originally described as a subspecies of C. bibronii (now regarded as limited to South Africa, southern Namibia and adjacent areas; Benyr 1995; Bauer and Lamb 2005) based on material from Pico Azevedo (Schmidt 1933). Heinz (2011) provided evidence for the specific distinctness of C. pulitzerae; see Ceríaco et al. (2014) for brief discussion ofthe nomenclatural and taxonomic history of this taxon. One specimen (CAS 254920) represents topotypical material. The species was common and found hiding on shaded areas of rocky crevices, houses, and other structures.

description: Nuclear magnetic resonance, electron paramagnetic resonance and magnetization measurements show that bulk Li$_x$ZnPc are strongly correlated one-dimensional metals. The temperature dependence of the nuclear spin-lattice relaxation rate $1/T_1$ and of the static uniform susceptibility $χ_S$ on approaching room temperature are characteristic of a Fermi liquid. Moreover, while for $x\simeq 2$ the electrons are delocalized down to low temperature, for $x\to 4$ a tendency towards localization is noticed upon cooling, yielding an increase both in $1/T_1$ and $χ_s$. The $x$-dependence of the effective density of states at the Fermi level $D(E_F)$ displays a sharp enhancement for $x\simeq 2$, at the half filling of the ZnPc lowest unoccupied molecular orbitals. This suggests that Li$_x$ZnPc is on the edge of a metal-insulator transition where enhanced superconducting fluctuations could develop.

description: Ultra metal-poor stars (UMPs, [Fe/H]<-4) are extremely rare objects located mainly in the Milky Way halo. Because they are ultra metal-poor, also relative to their neighbourhood, it is assumed that they formed in the relative pristine Galaxy short after the Big Bang. As such, they belong to the earliest generations of stars formed in the Universe. Because of their age (> 11 Gyr), observable UMPs must be low-mass stars, but the minimum metallicity at which low-mass stars can form is still an open question. The search for, and study of, stars at the lowest metallicities are therefore important tools to answer questions on the masses of the first generation of stars and the universality of the IMF, as well as on the early formation stages of galaxies and the first supernovae.

Thanks to the exquisite photometric and astrometric information from Gaia DR2, we discovered that, even though most UMP stars have properties that link them to the inner halo or the accreted halo, a strikingly large fraction (26%) of these objects follow disc-like orbits and, in particular, the most metal poor star known (the Caffau's star) has a quasi-circular orbit. One intriguing interpretation is that these stars with disc-like orbits belonged to the massive building block(s) of the proto-Milky Way that formed the backbone of the MW disc. Alternatively, they might have formed in the early disc and have been dynamically heated, or have been brought into the Milky Way by one or more accretion events whose orbit was dragged into the plane by dynamical friction before disruption.

description: The cosmic abundance of the 3-He isotope has important implications for many fields of astrophysics. We are using the 8.665 GHz hyperfine transition of 3-He+ to determine the 3-He/H abundance in Milky Way HII regions and planetary nebulae. This is one in a series of papers in which we discuss issues involved in deriving accurate 3-He/H abundance ratios from the available measurements. Here we describe the ionization correction we use to convert the 3-He+/H+ abundance, y3+, to the 3-He/H abundance, y3. In principle the nebular ionization structure can significantly influence the y3 derived for individual sources. We find that in general there is insufficient information available to make a detailed ionization correction. Here we make a simple correction and assess its validity. The correction is based on radio recombination line measurements of H+ and 4-He+, together with simple core-halo source models. We use these models to establish criteria that allow us to identify sources that can be accurately corrected for ionization and those that cannot. We argue that this effect cannot be very large for most of the sources in our observational sample. For a wide range of models of nebular ionization structure we find that the ionization correction factor varies from 1 to 1.8. Although large corrections are possible, there would have to be a conspiracy between the density and ionization structure for us to underestimate the ionization correction by a substantial amount.

The targum (1948:Feb. 3 - 1948:Feb. 27)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1948

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Pachydactylus angolensis (Loveridge, 1944)
MATERIAL.— Namibe-Lubango road, 2 km E (by road) of Mangueiras, south side of the road, 5 December 2013, 15º2ʹ37ʺS, 13º9ʹ36ʺE, 625 m (CAS 254887).
COMMENTS.— This poorly known taxon was described from Benguela Province (Loveridge 1944a). Laurent (1964a) subsequently reported additional specimens from the “environs de Moçâmedes” (now Namibe, Namibe Province). More recently, Wulf Haacke collected 16 specimens from both Bengela and Namibe Provinces. The Namibe localities include Lungo, Lucira, San Nicolau, and Saco de Giraul. There is a single record from extreme northern Namibia (J. Boone, pers. comm.), suggesting that the species actually has a fairly broad range from south of the Kunene to Hanha in Benguela (TM 46558).

COMMENTS.— The species is known from southwestern Angola in the provinces of Benguela (Bocage 1867, 1895; Boulenger 1885; Hellmich 1957b; Laurent 1954), Huila (Monard 1931, 1937, Laurent 1964a), Cunene (Laurent 1964a), and Namibe (Schmidt 1933, Laurent 1964a). Members of the P. punctatus complex have been confused with other southern African Pachydactylus, including P. occellatus and P. geitje (Bocage 1867, 1885, 1895; Boulenger 1905; Frade 1963). The previous report of P. serval in Angola (Monard 1931) likely corresponds to P. punctatus. A phylogeographic study of P. punctatus is being currently undertaken (Heinz 2011) and it appears that this taxon comprises multiple unnamed cryptic species. At least two, possibly three, taxa in this complex occur in southwestern Angola. Pachydactylus punctatus sensu lato is the most common terrestrial gecko in most of northern Namibia as well as southern Angola.

Equivalently, we completely describe when certain sequences of ratios of factorial products are always integral. Essentially, once certain observations are made, this comes down to an application of Beukers and Heckman's classification of the monodromy of the hypergeometric function nF_{n-1}. We also note applications to the classification of cyclic quotient singularities.

Barriers to the uptake of agroforestry in the UK
Creators: name: Westaway, Sally

Subjects: silvoarable; silvopastoral; agroforestry adoption

description: Agroforestry farming systems are receiving increasing recognition across Europe for their economic, environmental and welfare benefits as we look for ways to sustainably intensify agricultural production and increase resilience to climatic uncertainty. In 2017 there were 547,600 ha of silvopastoral agroforestry recorded in the UK and only 2000 ha of silvoarable agroforestry (Den Herder et al., 2017). Agroforestry in the UK offers great potential, and a few pioneer farmers have developed successful, innovative and profitable agroforestry projects on their land. However, the number of people talking about agroforestry doesn't match the number of people implementing new systems and we wanted to understand better the barriers to uptake in the UK. As part of the EU-funded AgroForestry Innovation NETworks (AFINET) project we wanted to find out what was limiting uptake of agroforestry in the UK and how to help those farmers that are interested but not yet making the next step towards planting trees.

MATERIAL.— Omauha Lodge, 28 November 2013, 16º11ʹ55.01ʺS, 12º24ʹ3.12ʺE, 338 m (CAS 254829).
COMMENTS.— Pachydactylus oreophilus was described from near Sesfontein in northwestern Namibia. Specimens assigned to this species extend northwards at least as far as the southern lowland portions of Benguela Province, Angola. Preliminary molecular phylogenetic data suggest that northern populations, including all of those in Angola and possibly those along the Kunene River in Namibia, are not conspecific with the nominotypic form. The specimen was collected at night, basking near a lamp 2.5 m off the ground, in Omauha Lodge.

COMMENTS.— Until now, this species has been known only from one published locality in Angola. Laurent (1964a) cites the specimen from a locality “ 60 km on the road from Moçâmedes [presently Namibe] to Sá da Bandeira [presently Lubango]”, the same locality from which he described R. taeniostictus, which we also collected (see account below). This species is widely distributed in northwestern Namibia, occurring as far inland as the Otavi-Grootfontein region, due south of western Cuando Cubango Province. It is rupicolous and can be found on small rocky piles and ridges, as well as on larger boulders. The extent of its distribution in Angola is poorly known, in part becase many records from Namibe and Huila are assignable to a morphologically similar, but undescribed congener (see Rhoptropus sp. below).

COMMENTS.— The species occurs in the rocky outcrops in arid habitats inland of the northern Namib dune fields in the vicinity of Orupembe, in the Kaokoveld and across the Cunene River to Angola (Bauer and Good 1996). The only published record of this species for Angola is from the Pico Azevedo region (Bauer and Good 1996), although Wulf Haacke collected numerous specimens from localities across southern Namibe, as well as from near Otchinjau, Cunene Province (specimens in Ditsong National Museum of Natural History).

description: We apply the fermion renormalization group method, implemented numerically by Honerkamp et.al., to a two-band model of FeAs-based materials. At half filling we find the $(π,0)$ or $(0,π)$ spin density wave order and a sub-dominant superconducting pairing tendency. Due to a topological reason, the spin density wave gap has nodes on the fermi surfaces. Away from half filling we find an unconventional s-wave and a sub-dominant $d_{x^2-y^2}$ pairing instability. The former has $s$ symmetry around the hole fermi surface but exhibits $s+d_{x^2-y^2}$ symmetry around the electron pockets where the 90 degree rotation is broken. The pairing mechanism is inter-pocket pair hopping. Interestingly, the same interaction also drives the antiferromagnetism.
