description: We argue that all locality-preserving mappings between fermionic observables and Pauli matrices on a two-dimensional lattice can be generated from the exact bosonization in Ref. [1], whose gauge constraints project onto the subspace of the toric code with emergent fermions. Starting from the exact bosonization and applying Clifford finite-depth generalized local unitary (gLU) transformation, we can achieve all possible fermion-to-qubit mappings (up to the re-pairing of Majorana fermions). In particular, we discover a new super-compact encoding using 1.25 qubits per fermion on the square lattice, which is lower than any method in the literature. We prove the existence of fermion-to-qubit mappings with qubit-fermion ratios $r=1+ \frac{1}{2k}$ for positive integers $k$, where the proof utilizes the trivialness of quantum cellular automata (QCA) in two spatial dimensions. When the ratio approaches 1, the fermion-to-qubit mapping reduces to the 1d Jordan-Wigner transformation along a certain path in the two-dimensional lattice. Finally, we explicitly demonstrate that the Bravyi-Kitaev superfast simulation, the Verstraete-Cirac auxiliary method, Kitaev's exactly solved model, the Majorana loop stabilizer codes, and the compact fermion-to-qubit mapping can all be obtained from the exact bosonization.

description: Speech recognition in adverse real-world environments is highly affected by reverberation and nonstationary background noise. A well-known strategy to reduce such undesired signal components in multi-microphone scenarios is spatial filtering of the microphone signals. In this article, we demonstrate that an additional coherence-based postfilter, which is applied to the beamformer output signal to remove diffuse interference components from the latter, is an effective means to further improve the recognition accuracy of modern deep learning speech recognition systems. To this end, the recently updated 3rd CHiME Speech Separation and Recognition Challenge (CHiME-3) baseline speech recognition system is extended by a coherence-based postfilter and the postfilter's impact on the word error rates is investigated for the noisy environments provided by CHiME-3. To determine the time- and frequency-dependent postfilter gains, we use a Direction-of-Arrival (DOA)-dependent and a DOA-independent estimator of the coherent-to-diffuse power ratio as an approximation of the short-time signal-to-noise ratio. Our experiments show that incorporating coherence-based postfiltering into the CHiME-3 baseline speech recognition system leads to a significant reduction of the word error rate scores for the noisy and reverberant environments provided as part of CHiME-3.

description: Gallium Phosphide (GaP) is a good candidate to be the top junction solar cell in a multi-junction solar
cell system. In this work GaP solar cells have been designed, fabricated, characterized and analyzed to be the top
junction solar cell in a five-junction solar cell system. Liquid phase epitaxy (LPE) has been used to grow the epitaxial
layers. Different n-type dopant sources have been used and investigated. Open circuit voltage (Voc) of 1.59V has been
achieved under one sun illumination when using Si as the n-type dopant material. Quantum efficiency (QE)
measurements were used to characterize the solar cell devices. The QE analysis results show that the high front surface
recombination velocity and the low diffusion length in the n-type epi-layer region are the two major limitations for the
Voc and short circuit current density (Jsc).

description: Estimating the distance of a gas source is important in many applications of chemical sensing, like e.g. environmental monitoring, or chemically-guided robot navigation. If an estimation of the gas concentration at the source is available, source proximity can be estimated from the time-averaged gas concentration at the sensing site. However, in turbulent environments, where fast concentration fluctuations dominate, comparably long measurements are required to obtain a reliable estimate. A lesser known feature that can be exploited for distance estimation in a turbulent environment lies in the relationship between source proximity and the temporal variance of the local gas concentration - the farther the source, the more intermittent are gas encounters. However, exploiting this feature requires measurement of changes in gas concentration on a comparably fast time scale, that have up to now only been achieved using photo-ionisation detectors. Here, we demonstrate that by appropriate signal processing, off-the-shelf metal-oxide sensors are capable of extracting rapidly fluctuating features of gas plumes that strongly correlate with source distance. We show that with a straightforward analysis method it is possible to decode events of large, consistent changes in the measured signal, so-called 'bouts'. The frequency of these bouts predicts the distance of a gas source in wind-tunnel experiments with good accuracy. In addition, we found that the variance of bout counts indicates cross-wind offset to the centreline of the gas plume. Our results offer an alternative approach to estimating gas source proximity that is largely independent of gas concentration, using off-the-shelf metal-oxide sensors. The analysis method we employ demands very few computational resources and is suitable for low-power microcontrollers.

description: There are different methods to reduce stress on solar cells within a module such as using
interconnectors with a lower coefficient of thermal expansion (CTE) – in order to match better with Silicon - or
applying of conductive adhesives instead of soldering.
This paper is focusing on the impact of yield strength on the internal stress of the solar cell revealing the usage of
copper ribbon with low yield strength as a promising material to interconnect solar cells even thinner as nowadays
standard. Accordingly, the influence of the yield strength of the interconnector on the module reliability is
demonstrated. Full-size modules have been built using different ribbon types with different yield strength values.
After mechanical stress test each module has been exposed to accelerated lifetime tests. The stress which is mainly
caused by interconnecting and soldering causes significant module power degradation after accelerate life time
testing. The thermo-mechanical balance between cell and interconnector is one of the main issues for high
performance and reliability of the modules. Additionally the physical limits for yield strength of a copper ribbon are
discussed. Cell breakage strength, tensile test, IV-curve and electroluminescence have been used for detailed
evaluation.

HOLOTYPE: AMNH 692233, adult male, collected on Mount Donelly, 34.20S, 117.43E (USBGN, 1957), Stirling Range, Western Australia, Australia, on 14 October 1910, by F. Lawson Whitlock. From the Mathews Collection (no. 6143) via the Rothschild Collection. COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range as the ‘‘ Stirling Range.’’ The type bears Whitlock’s original label, Mathews and Rothschild type labels and a ‘‘ Figured’ ’ label, indicating that it was illustrated in Mathews (1925a: pl. 544, opp. p. 14, text p. 26) where it is confirmed as the type of inexpectata. There are four paratypes in AMNH: Lake Balicup, 12 September 1910, AMNH 692231 (Mathews no. 6146), male, AMNH 692232 (6147), female; Mount Donelly, 14 October 1910, AMNH 692234 (6144), female; Stirling Range, 4 September 1910, AMNH 692236 (6145), male. AMNH 692235, collected by Whitlock in the Stirling Range on 26 Oct. 1911, was not cataloged by Mathews until the end of February 1912 [as dulciae (sic)], after the 31 January 1912 publication date of inexpectata and is not considered a paratype.

description: We present the first calculation of the one-loop corrections to the triple Higgs coupling in the framework of a simplified 3+1 Dirac neutrino model, that is three light neutrinos plus one heavy neutrino embedded in the Standard Model (SM). The triple Higgs coupling is a key parameter of the scalar potential triggering the electroweak symmetry-breaking mechanism in the SM. The impact of the heavy neutrino can be as large as $+20\%$ to $+30\%$ for parameter points allowed by the current experimental constraints depending on the tightness of the perturbative bound. This can be probed at the high-luminosity LHC, at future electron-positron colliders and at the Future Circular Collider in hadron-hadron mode, an envisioned 100 TeV $pp$ machine. Our calculation, being done in the mass basis, can be extended to any model using the neutrino portal. In addition, the effects that we have calculated are expected to be enhanced if additional heavy fermions with large Yukawa couplings are included, as in low-scale seesaw mechanisms.

description: Volumetric neural rendering methods like NeRF generate high-quality view synthesis results but are optimized per-scene leading to prohibitive reconstruction time. On the other hand, deep multi-view stereo methods can quickly reconstruct scene geometry via direct network inference. Point-NeRF combines the advantages of these two approaches by using neural 3D point clouds, with associated neural features, to model a radiance field. Point-NeRF can be rendered efficiently by aggregating neural point features near scene surfaces, in a ray marching-based rendering pipeline. Moreover, Point-NeRF can be initialized via direct inference of a pre-trained deep network to produce a neural point cloud; this point cloud can be finetuned to surpass the visual quality of NeRF with 30X faster training time. Point-NeRF can be combined with other 3D reconstruction methods and handles the errors and outliers in such methods via a novel pruning and growing mechanism. The experiments on the DTU, the NeRF Synthetics , the ScanNet and the Tanks and Temples datasets demonstrate Point-NeRF can surpass the existing methods and achieve the state-of-the-art results.

description: Layers of Si nanocrystals in a dielectric matrix have promising properties as an absorber layer in a top cell of a Si-based
tandem solar cell. Si nanocrystals in SiC are produced by plasma deposition of Si rich a-SixC1-x:H and solid phase
crystallization by thermal annealing at temperatures between 800°C and 1000°C. The Si rich a- SixC1-x:H films were
doped with boron by addition of diluted diborane (B2H6 in H2) to the plasma process. The microstructure was
investigated for different gas fluxes and annealing procedures and the films were found to consist of amorphous or
polycrystalline SiC with embedded Si nanocrystals. The microstructural results were then correlated with the electrical
and optoelectronic properties. By choosing appropriate deposition parameters, the films micro-structure could be
modified such that the crystallization of both Si and SiC nanocrystals is favoured and the conductivity is enhanced.
Glancing incidence X-ray diffraction patterns can show the formation of both Si and SiC nanocrystals after annealing at
900 °C, if the hydrogen flux in the plasma is large enough. The formation of SiC nanocrystals is confirmed by Fourier
Transformed Infrared spectra where a transition from a Gaussian shaped peak of the amorphous SiC-phase to a
blueshifted Lorentzian peak of nanocrystalline SiC is observed. Dark DC IV measurements reveal the increase of
conductivity with diluted diborane flux from 9.32 10-6 Ω−1cm−1 to 1.98 10-2 Ω−1cm−1 for a 1000 °C anneal. Increase of
annealing temperature at constant gas flux also increases conductivity by about two orders of magnitude.

description: Computationally intensive algorithms such as Deep Neural Networks (DNNs) are becoming killer applications for edge devices. Porting heavily data-parallel algorithms on resource-constrained and battery-powered devices poses several challenges related to memory footprint, computational throughput, and energy efficiency. Low-bitwidth and mixed-precision arithmetic have been proven to be valid strategies for tackling these problems. We present Dustin, a fully programmable compute cluster integrating 16 RISC-V cores capable of 2- to 32-bit arithmetic and all possible mixed-precision permutations. In addition to a conventional Multiple-Instruction Multiple-Data (MIMD) processing paradigm, Dustin introduces a Vector Lockstep Execution Mode (VLEM) to minimize power consumption in highly data-parallel kernels. In VLEM, a single leader core fetches instructions and broadcasts them to the 15 follower cores. Clock gating Instruction Fetch (IF) stages and private caches of the follower cores leads to 38\% power reduction with minimal performance overhead (<3%). The cluster, implemented in 65 nm CMOS technology, achieves a peak performance of 58 GOPS and a peak efficiency of 1.15 TOPS/W.

description: Background: The analysis of exhaled breath condensate (EBC) can be an alternative to traditional endoscopic sampling of lower respiratory tract secretions. This is a simple non-invasive method of diagnosing respiratory diseases, in particular, respiratory inflammatory processes. Methods: Samples were collected with a special device-condenser (ECoScreen, VIASYS Healthcare, Germany), then treated with trypsin according to the proteomics protocol for standard protein mixtures and analyzed by nanoflow high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) with a 7-Tesla Finnigan LTQ-FT mass spectrometer (Thermo Electron, Germany). Mascot software (Matrixscience) was used for screening the database NCBInr for proteins corresponding to the peptide maps that were obtained. Results: EBCs from 17 young healthy non-smoking donors were collected. Different methods for concentrating protein were compared in order to optimize EBC preparations for proteomic analysis. The procedure that was chosen allowed identification of proteins exhaled by healthy people. The major proteins in the condensates were cytoskeletal keratins. Another 12 proteins were identified in EBC from healthy non-smokers. Some keratins were found in the ambient air and may be considered exogenous components of exhaled air. Conclusions: Knowledge of the normal proteome of exhaled breath allows one to look for biomarkers of different disease states in EBC. Proteins in ambient air can be identified in the respiratory tract and should be excluded from the analysis of the proteome of EBC. The results obtained allowed us to choose the most effective procedure of sample preparation when working with samples containing very low protein concentrations. Clin Chem Lab Med 2009;47:706–12.

of encapsulant using DC and AC techniques. The elevated temperature 80 °C and humidity close to 100 % RH were
applied for 24 weeks in order to stress the samples. Elevated temperature and humidity accelerate the degradation
process in laboratory conditions. We have shown that DC measurement and polarization index kp calculation,
commonly used in electric insulation measurements technique, can represent important information about PV
encapsulant behavior.

description: We run numerical simulations of strongly confined suspensions of model spherical swimmers called "squirmers". Because of the confinement, the Stokeslet dipoles generated by the particles are quickly screened and the far-field flow is dominated by the source dipole for all the different kinds of squirmers. However, we show that the collective behavior of the suspension still depends on the self-propelling mechanism of the swimmers as polar states can only be observed for neutral squirmers. We demonstrate that the near-field hydrodynamic interactions play a crucial role in the alignment of the orientation vectors of spherical particles. Moreover, we point out that the enstrophy and the fluid fluctuations of an active suspension also depend on the nature of the squirmers.

description: Geometric deep learning has sparked a rising interest in computer graphics to perform shape understanding tasks, such as shape classification and semantic segmentation. When the input is a polygonal surface, one has to suffer from the irregular mesh structure. Motivated by the geometric spectral theory, we introduce Laplacian2Mesh, a novel and flexible convolutional neural network (CNN) framework for coping with irregular triangle meshes (vertices may have any valence). By mapping the input mesh surface to the multi-dimensional Laplacian-Beltrami space, Laplacian2Mesh enables one to perform shape analysis tasks directly using the mature CNNs, without the need to deal with the irregular connectivity of the mesh structure. We further define a mesh pooling operation such that the receptive field of the network can be expanded while retaining the original vertex set as well as the connections between them. Besides, we introduce a channel-wise self-attention block to learn the individual importance of feature ingredients. Laplacian2Mesh not only decouples the geometry from the irregular connectivity of the mesh structure but also better captures the global features that are central to shape classification and segmentation. Extensive tests on various datasets demonstrate the effectiveness and efficiency of Laplacian2Mesh, particularly in terms of the capability of being vulnerable to noise to fulfill various learning tasks.

description: In this contribution, we present semitransparent small molecule organic solar cells (OSC). If only the
standard absorber materials zinc phthalocyanine (absorption 600-750 nm) and C60 (absorption maximum at 450 nm)
are used, many OSC suffer from narrow absorption bands. We present devices that employ bulk heterojunctions of
dibenzoperiflanthene and C60 to achieve uniform coverage of a wide part of the solar spectrum to utilise a wide
wavelength range. Using thin multilayer metal contacts and organic capping layers, we achieve in first experiments
semitransparent OSC (“power windows”) with a power conversion efficiency of 1.6 ± 0.1%, having a high open
circuit voltage of 0.81 V. By using only nm-thin metal electrodes, the OSC can be made without ITO or other
transparent conductive oxides.

description: In view of the properties of mesons in hot strongly interacting matter the properties of the solutions of the truncated Dyson-Schwinger equation for the quark propagator at finite temperatures within the rainbow-ladder approximation are analysed in some detail. In Euclidean space within the Matsubara imaginary time formalism the quark propagator is not longer a O(4) symmetric function and possesses a discrete spectra of the fourth component of the momentum. This makes the treatment of the Dyson-Schwinger and Bethe-Salpeter equations conceptually different from the vacuum and technically much more involved. The question whether the interaction kernel known from vacuum calculations can be applied at finite temperatures remains still open. We find that, at low temperatures, the model interaction with vacuum parameters provides a reasonable description of the quark propagator, while at temperatures higher than a certain critical value $T_c$ the interaction requires stringent modifications. The general properties of the quark propagator at finite temperatures can be inferred from lattice QCD calculations. We argue that, to achieve a reasonable agreement of the model calculations with that from lattice QCD, the kernel is to be modified in such a way as to screen the infra-red part of the interaction at temperatures larger than $T_c$. For this, we analyse the solutions of the truncated Dyson-Schwinger equation with existing interaction kernels in a large temperature range with particular attention on high temperatures in order to find hints to an adequate temperature dependence of the interaction kernel to be further implemented in to the Bethe-Salpeter equation for mesons. This will allow to investigate the possible in medium modifications of the meson properties as well as the conditions of quark deconfinement in hot matter.

Zur Verbesserung der fuer die spannungsfreie Reparation erforderlichen Netzimplantate wurde in einer Tierstudie versucht, die bislang durch Resorption ungenuegende mechanische Stabilitaet eines resorbierbaren Polyglycolsaeure-Netzes durch Zugabe von Fibrinkleber bzw. humanen thrombozytaeren Wachstumsfaktoren zu verbessern. Hierdurch gelang ein signifikanter Anstieg der mechanischen Stabilitaet, so daß in dem verwendeten Tiermodell keine Herniationen auftraten.
description: In a prospective-randomized study conventional Shouldice operation was compared with tension-free procedures using mesh implantation in endoscopic (transabdominal preperitoneal mesh repair, TAPP) and open technique (Plug and patch repair; PP) for inguinal hernia repair. Regarding the mean end point postoperative pain both tension-free procedures (TAPP, PP) revealed significantly better results than Shouldice operation. Complications were comparable between the groups but duration of postoperative restrictions was significantly shorter after both tension-free procedures. To improve mesh quality for tension-free hernia repair an animal experiment was performed using a resorbable polyglycolic acid mesh. Despite good incorporation this mesh shows insufficient tensile strength due to absorption. Application of fibrin glue or platelet releasates significantly improve the mechanical stability of the repair protecting against herniation in this animal model.

description: We investigate the relation between indistinguishability and quantum entanglement in Hong- Ou-Mandel-interference experiments theoretically and relate these quantum mechanical principles to the theorem of entanglement monogamy. Employing Glaubers theory of quantum coherence we compute the detection statistics in HOM-interference of frequency entangled photons, and find a new additional term in the coincidence detection probability, which is related to the spectral indistinguishability of the considered photons that arises from finite bandwidth effects, and therefore is relevant in the limit of low frequency separations or large single-photon bandwidths. Compared to previous work in that context we treat all photonic degrees of freedom (DOF) on equal footing.

description: The mechanisms and environmental influences that cause photovoltaic modules performance
degradation are poorly understood, but it is well known that water vapour is deeply implicated in the degradation
process. Indeed, some layers and interfaces of thin film modules can be moisture sensitive and depending on the
processing conditions, they degrade after exposure to damp heat conditions (85°C, 85% relative humidity) [1].
Transparent conductive oxides (TCO), as used in CIGS or thin silicon film cells play a particular role linked to
reliability issues. We showed recently that low-pressure chemical vapour deposition zinc oxide (LPCVD ZnO) can
withstand damp heat test even without encapsulant providing doping of the ZnO is high enough, though this is
unfavourable for free carrier absorption (reduction of spectral response in the infrared part) [2]. Reduction of doping
leads to improved optical properties but needs therefore an optimized encapsulation strategy to avoid the deterioration
of the TCO conductivity.
In previous work, the degradation of LPCVD ZnO used in thin-film silicon solar cells was investigated [3]. It was
shown that the decrease of the ZnO conductivity was essentially due to the humidity increasing inside the
encapsulant. However other effects take part in the degradation process and remained yet unexplained.
In this paper we will report on several other possible sources of degradation, which have been identified. In order to
demonstrate and quantify these effects, we used various encapsulants, but without back protection (foil or glass), and
we exposed the samples to different type of atmospheres. The resistivity of the ZnO was monitored using an
inductive contactless and a four points probe methods. Finally, schemes to perform highly reliable laminates when
using lightly doped ZnO are proposed.

description: In order to face a shortage of silicon feedstock used to grow multicrystalline ingots, a solution can come from the direct purification of upgraded metallurgical silicon by means of a plasma torch, followed by a directional crystallization which induces a marked segregation of impurities. Mc-Si ingots were prepared and it is found that both B and P concentrations in the wafers are in the 1017cm-3range, so the material is quasi compensated and the first two thirds of the ingot are p-type while the top (solidified last) is n- type. In the p-type wafers, minority carrier diffusion lengths Ln are ~ 35 μm in the raw wafers and increase up to 120 μm after P diffusion and Al-Si alloy formation. We verify that in ingots
prepared by the same growth technique and using the same feedstock, the advantages of n-type vs p-type mc-Si wafers are maintained: Lp is found 3 times higher than Ln and increases up to 250 μm after P diffusion at 850 °C for 30 min. Front side junction solar cells could be made, but rear side junction cells could also work, provided the wafer thickness is reduced to 100 μm.

been developed. LPE grown photovoltaic cells with a single p-n-junction based on AlGaAs, GaAs and GaSb for the
wavelength range of 350-1800 nm have been developed and optimized. The effect of etching by means of anodic
oxidation of Zn diffused emitter on the behaviour of characteristics of GaSb solar cells was investigated. The total PV
efficiency of AlGaAs, GaAs, GaSb solar cells for the module with the splitting of the spectrum optimized for the

description: Effects of pulse magnetic field on the optical transmission properties of thin ferrofluid (FF) layers were experimentally investigated. It was observed that, under an influence of an external uniform magnetic field, pulses applied to the samples surfaces in normal direction decrease the optical transmission with further returning it to its original state, even before the end of the field pulse. The dependencies of the observed effects on the magnetic pulse magnitude and the samples thickness were investigated. The experimental results are explained using FF columnar aggregates growth and lateral coalescence under influence of a magnetic field, leading to a light scattering type Rayleigh-to-Mie transition. Further evolution of this process comes to a geometrical optics scale and respective macroscopic observable opaque FF columnar aggregates emergence. These changes of optical transmission are non-monotonic during the magnetic field pulse duration with minimal value in the case of Mie scattering, which is known as a magneto-optical extinction trend inversion. The residual inversion was detected after the external magnetic field pulse falling edge. Using molecular dynamics simulation, we showed that a homogeneous external magnetic field is enough for the formation of columnar aggregates and their fusion. The results clarify the known Li theory (Li et al., J. Phys. D: Appl. Phys. 37 (2004) 3357, and Sci. Technol. Adv. Mate. 8 (2007) 448), implying an inhomogeneous field as a required prerequisite for the magneto-optical extinction trend inversion phenomenon.

 Abstract Satralizumab (Enspryng®) is a monoclonal antibody that blocks the interleukin-6 (IL-6) receptor and is approved for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in patients who are aquaporin-4 immunoglobulin G (AQP4-IgG) seropositive. Patients with NMOSD are at risk of recurrent autoimmune attacks that primarily target the optic nerves and spinal cord but may also target other regions of the central nervous system; these attacks can lead to life-long disability. In the randomized, placebo-controlled phase III SAkuraSky and SAkuraStar trials, subcutaneous satralizumab as an add-on to immunosuppressive therapy or as a monotherapy, respectively, significantly reduced the risk of relapse compared with placebo in patients who were AQP4-IgG seropositive with NMOSD. Satralizumab was well tolerated; the most common adverse events were infection, headache, arthralgia, decreased white blood cell count, hyperlipidaemia and injection-related reactions. In the EU, satralizumab is the first IL-6 receptor blocker to be approved for treatment of AQP4-IgG-seropositive patients with NMOSD, has the potential advantage of subcutaneous administration, and is the only targeted treatment approved for adolescent patients with this disorder. Thus, satralizumab is a valuable treatment option for patients with NMOSD. © Springer Nature Switzerland AG 2023

description: Gliciphila albifrons incerta Mathews Gliciphila albifrons incerta Mathews, 1912a: 399 (Carina, Victoria). Now Purnella albifrons (Gould, 1841). See Salomonsen, 1967: 429, Schodde and Mason, 1999: 315, Christidis and Boles, 2008: 185–191, and Higgins et al., 2008: 609. HOLOTYPE: AMNH 691992, female, collected at Carina, 35.15S, 141.06E (USBGN, 1957), Victoria, Australia, on 25 September 1908. From the Mathews Collection (no. 3088) via the Rothschild Collection. COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range as ‘‘ New South Wales, Victoria, South Australia.’’ Two specimens are probable paratypes, but I do not know when Mathews acquired them as I did not find them in his catalog: AMNH 691985, female, collected at Tailem Bend, South Australia, on 25 September 1908; and AMNH 691986, male, collected at Underbool (Mallee), Victoria, on 13 September 1910. Four additional specimens are possible paratypes but may not have been in Mathews’ hand before the publication of incerta on 31 January 1912, nor did I find them cataloged: AMNH 691973, female, Leighs Creek, South Australia, 16 August 1911; AMNH 691994–691996, two males, one female, collected at Walpeup, Victoria, in November 1911. This species was included in the genus Phylidonyris, subgenus Purnella, by Schodde and Mason (1999: 315). DNA sequence data obtained by Driskell and Christidis (2004) indicated generic level differences. Purnella was used by Christidis and Boles (2008) and by Higgins et al. (2008: 609).
