description: The oldest ice core records are obtained from the East Antarctic Plateau. Water isotopes are key proxies to reconstructing past climatic conditions over the ice sheet and at the evaporation source. The accuracy of climate reconstructions depends on knowledge of all processes affecting water vapour, precipitation and snow isotopic compositions. Fractionation processes are well understood and can be integrated in trajectory-based Rayleigh distillation and isotope-enabled climate models. However, a quantitative understanding of processes potentially altering snow isotopic composition after deposition is still missing. In low-accumulation sites, such as those found in East Antarctica, these poorly constrained processes are likely to play a significant role and limit the interpretability of an ice core's isotopic composition.

By combining observations of isotopic composition in vapour, precipitation, surface snow and buried snow from Dome C, a deep ice core site on the East Antarctic Plateau, we found indications of a seasonal impact of metamorphism on the surface snow isotopic signal when compared to the initial precipitation. Particularly in summer, exchanges of water molecules between vapour and snow are driven by the diurnal sublimation-condensation cycles. Overall, we observe in between precipitation events modification of the surface snow isotopic composition. Using high-resolution water isotopic composition profiles from snow pits at five Antarctic sites with different accumulation rates, we identified common patterns which cannot be attributed to the seasonal variability of precipitation. These differences in the precipitation, surface snow and buried snow isotopic composition provide evidence of post-deposition processes affecting ice core records in low-accumulation areas.

description: By analytically continuing QCD scattering amplitudes through specific complexified momenta, one can study and learn about the nature and the consequences of factorization and unitarity. In some cases, when coupled with the largest time equation and gauge invariance requirement, this approach leads to recursion relations, which greatly simplify the construction of multi-gluon scattering amplitudes. The setting for this discussion is in the space-cone gauge.

description: Method developed by Sandalov and coworkers [Int. J. Quant. Chem. 94, 113 (2003)] is applied to inelastic transport in the case of strong correlations on the molecule, which is relatively weakly coupled to contacts. Ability of the approach to deal with the transport in the language of many-body molecular states as well as take into account charge-specific normal modes and nonadiabatic couplings is stressed. We demonstrate capabilities of the technique within simple model calculations, and compare it to previously published approaches.

description: The specific band structure of graphene, with its unique valley structure and Dirac neutrality point separating hole states from electron states has led to the observation of new electronic transport phenomena such as anomalously quantized Hall effects, absence of weak localization and the existence of a minimum conductivity. In addition to dissipative transport also supercurrent transport has already been observed. It has also been suggested that graphene might be a promising material for spintronics and related applications, such as the realization of spin qubits, due to the low intrinsic spin orbit interaction, as well as the low hyperfine interaction of the electron spins with the carbon nuclei. As a first step in the direction of graphene spintronics and spin qubits we report the observation of spin transport, as well as Larmor spin precession over micrometer long distances using single graphene layer based field effect transistors. The non-local spin valve geometry was used, employing four terminal contact geometries with ferromagnetic cobalt electrodes, which make contact to the graphene sheet through a thin oxide layer. We observe clear bipolar (changing from positive to negative sign) spin signals which reflect the magnetization direction of all 4 electrodes, indicating that spin coherence extends underneath all 4 contacts. No significant changes in the spin signals occur between 4.2K, 77K and room temperature. From Hanle type spin precession measurements we extract a spin relaxation length between 1.5 and 2 micron at room temperature, only weakly dependent on charge density, which is varied from n~0 at the Dirac neutrality point to n = 3.6 10^16/m^2. The spin polarization of the ferromagnetic contacts is calculated from the measurements to be around 10%.

description: We present an approach using quantum walks (QWs) to redistribute ultracold atoms in an optical lattice. Different density profiles of atoms can be obtained by exploiting the controllable properties of QWs, such as the variance and the probability distribution in position space using quantum coin parameters and engineered noise. The QW evolves the density profile of atoms in a superposition of position space resulting in a quadratic speedup of the process of quantum phase transition. We also discuss implementation in presently available setups of ultracold atoms in optical lattices.

description: Single crystals of BaRh_2As_2 have been synthesized from a Pb flux. We present the room temperature crystal structure, single crystal x-ray diffraction measurements as a function of temperature T, anisotropic magnetic susceptibility χversus T, electrical resistivity in the ab-plane ρversus T, Hall coefficient versus T and magnetic field H, and heat capacity C versus T measurements on the crystals. The single crystal structure determination confirms that BaRh_2As_2 forms in the tetragonal ThCr_2Si_2 type structure (space group I4/mmm) with lattice parameters a = b = 4.0564(6)Åand c = 12.797(4) Å. Band structure calculations show that BaRh_2As_2 should be metallic with a small density of states at the Fermi energy N(E_ F) = 3.49 states/eV f.u. (where f.u. \equiv formula unit) for both spin directions. ρ(T) data in the ab-plane confirm that the material is indeed metallic with a residual resistivity ρ(2K) = 29 μΩcm, and with a residual resistivity ratio ρ(310K)/ρ(2K) = 5.3. The observed χ(T) is small (\sim 10^{-5} cm^3/mol) and weakly anisotropic with χ_{ab}/χ_ c \approx 2. The C(T) data indicate a small density of states at the Fermi energy with the low temperature Sommerfeld coefficient γ= 4.7(9) mJ/mol K^2. There are no indications of superconductivity, spin density wave, or structural transitions between 2K and 300K. We compare the calculated density of states versus energy of BaRh_2As_2 with that of BaFe_2As_2.

description: We consider the problem of coding for quantum channels with side information that is available ahead of time at the transmitter but not at the receiver. We find a single-letter expression for the entanglement-assisted quantum capacity of such channels which closely parallels Gel'fand and Pinsker's solution to the classical version of the same problem. This theorem can also be used to find a lower bound on the unassisted quantum capacity of these channels.

description: Genome streamlining is frequently observed in free-living aquatic microorganisms and results in physiological dependencies between microorganisms. However, we know little about the specificity of these microbial associations. In order to examine the specificity and extent of these associations, we established mixed cultures from three different freshwater environments and analyzed the cooccurrence of organisms using a metagenomic time series. Free-living microorganisms with streamlined genomes lacking multiple biosynthetic pathways showed no clear recurring pattern in their interaction partners. Free-living freshwater bacteria form promiscuous cooperative associations. This notion contrasts with the well-documented high specificities of interaction partners in host-associated bacteria. Considering all data together, we suggest that highly abundant free-living bacterial lineages are functionally versatile in their interactions despite their distinct streamlining tendencies at the single-cell level. This metabolic versatility facilitates interactions with a variable set of community members.

COMMENTS.— Pedioplanis haackei is one of the latest additions to the herpetofauna of Angola, and is endemic to southern Angola. Each of our specimens has 10 to 12 longitudinal rows of ventral scales, a semi-transparent lower eyelid with a brille formed of two large scales, five to six supralabials anterior to the subocular, two rows of granules separating supraoculars from supraciliaries, and the typical coloration with dots on the flanks, concordant with the diagnostic characters presented by Conradie et al. (2012) in the species description. Genetically, our specimens (GenBank accession numbers KU662311–KU662318) have an average 16S p-distance of 1% from those of Conradie et al. (2012) (GenBank accession numbers HE794000, HE793999.1; HE793998.1; HE793997.1; HE793996.1; HE793995.1; HE793994.1; HE793994.3).

description: The European Union’s LEADER programme, as an integral part of the Rural Development Programme, is perceived as an important, spatially oriented instrument of the current rural policy and Local Action Groups (LAGs) are the mainstay of the implementation of this developmental initiative. Only 29 LAGs were registered in Slovakia for the EU 2007-2013 programming period. They covered only 18% of the territory of the country and affected more than 618 thousand (11%) inhabitants in Slovakia. The situation dramatically changed during the next years. For the 2014-2020 programming period, 110 Local Action Groups with differentiated financial support for their approved individual Community-led local development (CLLD) strategies were registered in Slovakia. The aim of the present study is twofold. Firstly, it attempts to describe the process of innovative general and spatial diffusion of registered non-profit organizations from rural territories on the territory of Slovakia. We present this process stressing the specific position of Slovakia among the group of the EU Member States. Secondly, territorial areas (“regions”) covered by LAGs were selected for a detailed comparative intra-national analysis of their basic, geographically relevant characteristics (number of inhabitants and municipalities, proportion between urban and rural municipalities, and character of demographic development) by using the individual and aggregate statistical data for descriptive statistical analysis (tables) and cartographic presentation (maps).

MATERIAL.— Namibe-Lubango road, 2 km E of Mangueiras, south side of the road, 5 December 2013, 15º02ʹ37.0ʺS, 13º09ʹ36.0ʺE, 625 m (CAS 254885).
COMMENTS.— The species is widespread over much of southern Africa, particularly on sandy substrates (Bauer et al. 1993). In Angola, the majority of both bibliographic (Bocage 1867, 1895; Monard 1937; Mertens 1938; Boulenger 1921) and museum records (e.g., TM 46525) are from Benguela. However, there are also records of the species for Namibe Province from “Maconjo” (Bocage 1895), “Capangombe” (Bocage 1895), and “Konondoto” (Boulenger 1921). The species’ distribution in the country extends to the southeast in Huíla and Cunene Provinces. Our specimen is a sub-adult (55.5 mm SVL).

Vegetation-environment relationships in the tidal marshes of the Fraser River Delta, British Columbia
Creators: name: Porter, Glendon Leslie
Publisher: name: University of British Columbia
Year: 2010

description: The literature on North American Pacific Coast tidal marshes north of Mexico is summarized. Vegetation and environmental data from Fraser Delta tidal marshes at Ladner Marsh, Brunswick Point, and Boundary Bay were analyzed using principal components analysis and reciprocal averaging to investigate quantitative relationships between species performance and distribution, and selected environmental factors. These were: soil texture (percentage of sand, silt, and clay); soil concentration of nitrogen, potassium, calcium, magnesium, and sodium; and elevation (standardized by local tidal range). Ordinations were performed on both the vegetation and the environmental data sets. Different methods of data standardization (square root transformation, normalization, and correlation matrix) were tested for their usefulness in exposing ecological gradients. Normalization and square root transformation of the data were found to be useful in vegetation ordination; the correlation matrix was not. Reciprocal averaging and principal components analysis gave results of equivalent quality with the vegetation data, but principal components analysis was generally superior to reciprocal averaging in the environmental ordinations. The marshes of the study area separate conspicuously into two types on both floristic and environmental criteria: a fresh-to-brackish type at Ladner Marsh and in northern and western Brunswick Point, and a saline type in southeastern Brunswick Point and at Boundary Bay. Within each area, four main species-environment sample groups were informally recognized, dominated respectively by: (1.) Carex lyngbyei and Agrostis alba; (2.) Agrostis alba and Scirpus maritimus; (3.) Scirpus americanus; (4.) Equisetum fluviatile, Scirpus validus, Agrostis alba, and Alisma plantago-aquatica; (5.) Atriplex patula; (6.) Carex lyngbyei and Distichlis spicata; (7.) Salicornia virginica and Triqlochin maritimum; (8.) Spergularia canadensis. Patterns of performance and distribution of important tidal marsh species were shown to be related to levels of the measured environmental factors.

description: The paper is devoted to the analysis of the blow-ups of derivatives, gradient catastrophes and dynamics of mappings of $\mathbb{R}^n \to \mathbb{R}^n$ associated with the $n$-dimensional homogeneous Euler equation. Several characteristic features of the multi-dimensional case ($n>1$) are described. Existence or nonexistence of blow-ups in different dimensions, boundness of certain linear combinations of blow-up derivatives and the first occurrence of the gradient catastrophe are among of them. It is shown that the potential solutions of the Euler equations exhibit blow-up derivatives in any dimenson $n$. Several concrete examples in two- and three-dimensional cases are analysed. Properties of $\mathbb{R}^n_{\underline{u}} \to \mathbb{R}^n_{\underline{x}}$ mappings defined by the hodograph equations are studied, including appearance and disappearance of their singularities.

description: Recently, it has been shown that, when the dimension of a graph turns out to be infinite dimensional in a broad sense, the upper critical surface and the corresponding critical behavior of an arbitrary Ising spin glass model defined over such a graph, can be exactly mapped on the critical surface and behavior of a non random Ising model. A graph can be infinite dimensional in a strict sense, like the fully connected graph, or in a broad sense, as happens on a Bethe lattice and in many random graphs. In this paper, we firstly introduce our definition of dimensionality which is compared to the standard definition and readily applied to test the infinite dimensionality of a large class of graphs which, remarkably enough, includes even graphs where the tree-like approximation (or, in other words, the Bethe-Peierls approach), in general, may be wrong. Then, we derive a detailed proof of the mapping for all the graphs satisfying this condition. As a byproduct, the mapping provides immediately a very general Nishimori law.

description: Probabilistic programming languages aid developers performing Bayesian inference. These languages provide programming constructs and tools for probabilistic modeling and automated inference. Prior work introduced a probabilistic programming language, ProbZelus, to extend probabilistic programming functionality to unbounded streams of data. This work demonstrated that the delayed sampling inference algorithm could be extended to work in a streaming context. ProbZelus showed that while delayed sampling could be effectively deployed on some programs, depending on the probabilistic model under consideration, delayed sampling is not guaranteed to use a bounded amount of memory over the course of the execution of the program. In this paper, we present conditions on a probabilistic program's execution under which delayed sampling will execute in bounded memory. The two conditions are dataflow properties of the core operations of delayed sampling: the $m$-consumed property and the unseparated paths property. A program executes in bounded memory under delayed sampling if, and only if, it satisfies the $m$-consumed and unseparated paths properties. We propose a static analysis that abstracts over these properties to soundly ensure that any program that passes the analysis satisfies these properties, and thus executes in bounded memory under delayed sampling.

COMMENTS.— Based on a combination of morphological and molercular data, Stanley et al. (2016) described this new species endemic to the arid lowlands west of the southern Angolan escarpment. The majority of the type material of C. namakuiyus was collected during this trip. The new species is morphologically and genetically distinct from its sister taxon Cordylus machadoi Laurent, 1964, which occurs in the highlands of Huila, not far from Namibe. In addition to an average 7.1% uncorrected p-distance for the mitochondrial marker ND2, the two species differ in the extent of osteodermal armament. The more complete body armor of C. namakuiyus may be an adaptation to the semi-arid and refuge-scarce habitat where the species occurs. Within the new species there is also a degree of internal genetic structure, with specimens from Iona (PEM R18005) and Pico Azevedo (CAS 254754, 254755, 256530, 256531) more closely related to one another than to the two specimens from Caraculo. Specimens in the American Museum of Natural Histiry identified as Cordylus cordylus and collected in 1925 during the Vernay Expedition in Angola are assignable to C. namakuiyus. Although the Vernay specimens lack specific locality information, the expedition field notes mention that significant numbers of unidentified lizards were collected at “Pico Azevedo” and “ 100 km east of Moçâmedes” the same areas where we collected eight specimens of C. namakuiyus.

COMMENTS.— The species is known from the coastal areas of Benguela Province (Bocage 1867, 1895; Boulenger 1887) and from the Curoca River in Namibe Province (Bocage 1895). This specimen represents the southernmost record for Angola. The specimen was found hiding in a granite boulder crevice. Extralimitally, the species is widely distributed from the Little Karoo in the Western Cape of South Africa, north through the entire length of Namibia (Branch 1998).

Gerrhosaurus skoogi (Andersson, 1916)
MATERIAL.— Praia do Navio coastal dunes, ca 124 km SSW of Namibe, 8 December 2013, 16º16ʹ20.4ʺS, 11º49ʹ53.9ʺE, 8 m (CAS 254772), 16º16ʹ29.1ʺS, 11º49ʹ50.0ʺE, 8 m (CAS 254774), 16º16ʹ42.1ʺS, 11º49ʹ21.7ʺE, 8 m (CAS 254777).
COMMENTS.— This species was encountered basking at the sun in the coastal dunes SSW of Namibe, especially in dune valleys areas. When approached, these lizards dive into the sand, disappearing rapidly. The species is easily identified by its unique morphology and peculiar ecology. Sand trails resulting from the specimens walking in the dunes were noted. A total of five specimens were collected, three of which are at CAS and two at INBAC. Several additional animals were observed in the area but not collected. Males have a distinct black throat and venter, and are considerably larger than the females. The only published Angolan records are from the type locality, Porto Alexandre, between Mossamedes and the mouth of the Cunene River (Andersson 1916; Fitzsimons 1953), approximately in the same area as our material. Although the species is the most distinctive of all Gerrhosaurus (Nance 2007), it is unambiguously nested among more typical taxa, implying its unique features are relatively recently derived autapomorphies (Lamb et al. 2003; Lamb and Bauer 2013).

description: We consider the coherent stimulated Raman process developing in an optically dense disordered atomic medium, which can also incoherently scatter the light over all outward directions. The Raman process is discussed in the context of a quantum memory scheme and we point out the difference in its physical nature from a similar but not identical protocol based on the effect of electromagnetically induced transparency (EIT). We show that the Raman and EIT memory schemes do not compete but complement one another and each of them has certain advantages in the area of its applicability. We include in our consideration an analysis of the transient processes associated with switching the control pulse off or on and follow how they modify the probe pulse dynamics on the retrieval stage of the memory protocol.

description: We perform a dynamical finite-size scaling analysis of a nonequilibrium Bose gas which is confined in the transverse plane. Varying the transverse size, we establish a dimensional crossover for universal scaling properties far from equilibrium. Our results suggest that some aspects of the dynamical universal behavior of anisotropic systems can be classified in terms of fractional spatial dimensions. We discuss our findings in view of recent experimental results with quasi one-dimensional setups of quenched ultracold quantum gases.

description: Despite being bright ($V=12$) and nearby ($d=212$ pc) ASAS J071404+7004.3 has only recently been identified as a nova-like cataclysmic variable. We present time-resolved optical spectroscopy obtained at the Isaac Newton Telescope together with $\textit{Swift}$ X-ray and ultraviolet observations. We combined these with $\textit{TESS}$ photometry and find a period of 3.28h and a mass transfer rate of $4-9 \times 10^{-9} M_{sun}/yr$. Historical photometry shows at least one low state establishing the system as a VY Scl star. Our high-cadence spectroscopy also revealed rapidly changing winds emanating from the accretion disc. We have modelled these using the Monte Carlo PYTHON code and shown that all the emission lines could emanate from the wind - which would explain the lack of double-peaked lines in such systems. In passing,we discuss the effect of variability on the position of cataclysmic variables in the $\textit{Gaia}$ Hertzsprung-Russell diagram.

Varanus albigularis angolensis Schmidt, 1933
MATERIAL.— 7.5 km NW (by road) of Pico Azevedo, adult, found in a rock crevice, 7 December 2013, 15º28ʹ33.6ʺS, 12º27ʹ41.4ʺE, 399 m (CAS 254768).
COMMENTS.— The subspecies was described from Gauca, Bihé (Bié) Province (Schmidt 1933). According to the original description, the subspecies differed from the nominotypic form by having larger scales everywhere on the body so that the scales around the body are about 125 instead of 150, and the transverse rows of scales from the collar to thighs are 75 instead of 100 (Schmidt 1933). Laurent (1964b) noted that the morphological differences between the nominotypic form and angolensis are quite subtle and that angolensis may, in fact, be a synonym of albigularis. However, Bayless (2002) considered the material from nearby localities, such as Bibala and Caraculo as V. a. angolensis. Given the currently accepted distribution of angolensis and the lower number of scales around the midbody and between the collar and the thighs, we tentatively identify our specimen as the Angolan subspecies. The subspecies appears to be the prevalent form in Angola (and possibly extending to some neighboring regions of the DRC, even if the nominotypic form occurs sympatrically, especially in the southern regions of the country (Bayless 2002).

description: Measures of democracy are in high demand. Scientific and public audiences use them to describe political realities and to substantiate causal claims about those realities. This introduction to the thematic issue reviews the history of democracy measurement since the 1950s. It identifies four development phases of the field, which are characterized by three recurrent topics of debate: (1) what is democracy, (2) what is a good measure of democracy, and (3) do our measurements of democracy register real-world developments? As the answers to those questions have been changing over time, the field of democracy measurement has adapted and reached higher levels of theoretical and methodological sophistication. In effect, the challenges facing contemporary social scientists are not only limited to the challenge of constructing a sound index of democracy. Today, they also need a profound understanding of the differences between various measures of democracy and their implications for empirical applications. The introduction outlines how the contributions to this thematic issue help scholars cope with the recurrent issues of conceptualization, measurement, and application, and concludes by identifying avenues for future research.

Python natalensis Smith, 1840
MATERIAL.— Beginning of the forested areas, at the start of the climb to Leba Pass (by road), near Bruco village, 5 December 2013, 15º07ʹ15.82ʺS, 13º11ʹ11.56ʺE. Individual observed but not collected.
COMMENTS.— A local at a site near Bruco village was selling a single live individual of Python natalensis, presumably collected nearby. In the province, this species is known from Maconjo (Bocage 1895; Broadley 1984) and from Giraul River (Bocage 1896; Broadley 1984). Python natalensis was for many years considered as a subspecies of Python sebae (Gmelin, 1789) (Broadley 1984), but was elevated to specific status by Broadley (1999) based on morphological differences as well the evidence of the overlapping distributions (Broadley and Cotterill 2004). Although the current taxonomic arrangement appears appropriate, molecular analyses are needed to conclusively resolve the relationship between P. natalensis and P. sebae (Alexander 2007). Spawls and Branch (1995) and Bellosa et al. (2007) provided maps with the distribution ranges for both species, with P. natalensis occurring in central and southern Angola, as far north as the Kwanza River, overlaping in Luanda Province with P. sebae, which occurs in northern regions of Angola, including Cabinda. According to the local selling this individual, this species is sometimes collected for food or sold to tourists as pets.

Psammophis notostictus Peters, 1867
MATERIAL.— Espinheira, 30 November 2013, 16º47ʹ13.8ʺS, 12º21ʹ27.5ʺE, 457 m (CAS 254827); Pico Azevedo, 7 December 2013, 15º32ʹ2.4ʺS, 12º29ʹ31.1ʺE, 359 m (CAS 254940).
COMMENTS.— Psammophis notostictus is easily recognizable from all other southern African Psammophis by its single cloacal shield and the presence of two preoculars (Broadley 1975b, 1977, 2002). These two specimens have both of these diagnostic characters. The species is known for Angola, but only from Namibe Province. The closest published records of the species are in Rio São Nicolau (Loveridge 1940; Broadley 1975b, 2002), Moçamedes [Namibe city] (Bocage 1887; Loveridge 1940), and Curoca River (Loveridge 1940; Broadley 2002). Our records expand the known distribution of the species further south in the country, although it is continuous southwards throughout much of western southern Africa (Branch 1998).

description: Recent experiments have demonstrated that the performances of organic FETs strongly depend on the dielectric properties of the gate insulator. In particular, it has been shown that the temperature dependence of the mobility evolves from a metallic-like to an insulating behavior upon increasing the dielectric constant of the gate material. This phenomenon can be explained in terms of the formation of small polarons, due to the polar interaction of the charge carriers with the phonons at the organic/dielectric interface. Building on this model, the possible consequences of the Coulomb repulsion between the carriers at high concentrations are analyzed.
