description: Zonotrichia capensis septentrionalis Griscom Zonotrichia capensis septentrionalis Griscom, 1930: 12 (Chichicastenango, Guatemala). Now Zonotrichia capensis septentrionalis Griscom, 1930. See Hellmayr, 1938: 571, Chapman, 1940: 390–391, Byers et al., 1995: 236–238, and Dickinson, 2003: 782. HOLOTYPE: AMNH 397976, adult male, collected at Chichicastenango, 14.56N, 91.07W (USBGN, 1965), El Quiche´, Guatemala; 27 January 1925, by Alfred W. Anthony. From the Dwight Collection (no. 60798). COMMENTS: The Dwight Collection number of the holotype was given in the original description. Griscom mentioned that he examined 84 specimens from 15 localities in the Guatemalan highlands, without giving specifics. Later, he (Griscom, 1932b: 363) listed his localities and the number of specimens from each, but I count only 82 specimens on his list. Of these, 64 were cataloged at AMNH. The 63 AMNH paratypes are: AMNH 397959– 397975, 397977–398022, 39 males, 20 females, 3 immatures, and 1 sex unknown; of these, I did not find AMNH 397959, sex?, from Antigua, in the collection. Subsequent to the publication by Griscom (1932b) on the entire Guatemalan collection and before it was cataloged at AMNH, a large number of the specimens were retained at MCZ. The remaining paratypes are probably there.

description: Population structure and spatial heterogeneity are integral components of evolutionary dynamics, in general, and of evolution of cooperation, in particular. Structure can promote the emergence of cooperation in some populations and suppress it in others. Here, we provide results for weak selection to favor cooperation on regular graphs for any configuration, meaning any arrangement of cooperators and defectors. Our results extend previous work on fixation probabilities of single, randomly placed mutants. We find that for any configuration cooperation is never favored for birth-death (BD) updating. In contrast, for death-birth (DB) updating, we derive a simple, computationally tractable formula for weak selection to favor cooperation when starting from any configuration containing any number of cooperators and defectors. This formula elucidates two important features: (i) the takeover of cooperation can be enhanced by the strategic placement of cooperators and (ii) adding more cooperators to a configuration can sometimes suppress the evolution of cooperation. These findings give a formal account for how selection acts on all transient states that appear in evolutionary trajectories. They also inform the strategic design of initial states in social networks to maximally promote cooperation. We also derive general results that characterize the interaction of any two strategies, not only cooperation and defection.

description: Good light trapping is essential to make high efficiency silicon solar cells. As silicon wafers are being
made increasingly thinner, light trapping becomes even more important. In this work we compare in simulations light
trapping from conventional random pyramid textures, with structure sizes of several microns, to that of light trapping
from diffractive structures with lattice periods comparable to the wavelength of light. More specifically we compare
light trapping in front-side and double-sided random pyramidal textures to that of two different back-side bi-periodic
structures applied to a 20 μm thick Si slab. We find that a photogenerated current density of 40.0 mA/cm2 is achieved
for a double-sided pyramidal texture with a rear oxide layer and a silver reflector. This is slightly higher than the best
diffractive structure with a planer front side and rear texture. The pyramidal textures show exceptional broad-band
anti-reflection behavior, while the diffractive structures excel in the long-wavelength part of the solar spectrum.

description: Following the ideas of effective field theories, we derive classically effective field equations of recently developed Lorentz gauge theory of gravity. It is shown that Newton's gravitational constant emerges as an effective coupling parameter if an extremely small length is integrated out of the underlying theory. The linear version of the effective theory is shown to be fully consistent with the Newtonian gravity. We also derive a numerical solution for the interior of a star and show that in the non-linear regions, the behavior of the effective theory deviates from the predictions of general relativity.

description: The closure of schools and healthcare facilities across the United States due to COVID-19 has dramatically changed the way that services are provided to children with disabilities. Little is known about how children who use augmentative and alternative communication (AAC), their families and their service providers have been impacted by these changes. This qualitative study sought to understand the perspectives of parents and speech-language pathologists (SLPs) on how COVID-19 has affected children, families, services providers and the delivery of AAC-related communication services. For the study, 25 parents and 25 SLPs of children who used aided AAC participated in semi-structured interviews, with data analyzed using qualitative thematic analysis. Parents and SLPs highlighted wide disparities in how children have been impacted, ranging from views of children making more progress with communication and language than before the pandemic to worries about regression. A complex system of factors and processes may explain these differences. COVID-19 will have lasting impacts on the lives of children with complex communication needs. This research highlights the crucial role of family-service provider partnerships and access to quality AAC services for children during the pandemic and into the future.
Theory of the Robin quantum wall in a linear potential. II. Thermodynamic properties

description: A theoretical analysis of the thermodynamic properties of the Robin wall characterized by the extrapolation length $Λ$ in the electric field $\mathscr{E}$ that pushes the particle to the surface is presented both in the canonical and two grand canonical representations and in the whole range of the Robin distance with the emphasis on its negative values which for the voltage-free configuration support negative-energy bound state. For the canonical ensemble, the heat capacity at $Λ<0$ exhibits a nonmonotonic behavior as a function of the temperature $T$ with its pronounced maximum unrestrictedly increasing for the decreasing fields as $\ln^2\mathscr{E}$ and its location being proportional to $(-\ln\mathscr{E})^{-1}$. For the Fermi-Dirac distribution, the specific heat per particle $c_N$ is a nonmonotonic function of the temperature too with the conspicuous extremum being preceded on the $T$ axis by the plateau whose magnitude at the vanishing $\mathscr{E}$ is defined as $3(N-1)/(2N)k_B$, with $N$ being a number of the particles. The maximum of $c_N$ is the largest for $N=1$ and, similar to the canonical ensemble, grows to infinity as the field goes to zero. For the Bose-Einstein ensemble, a formation of the sharp asymmetric feature on the $c_N$-$T$ dependence with the increase of $N$ is shown to be more prominent at the lower voltages. This cusp-like dependence of the heat capacity on the temperature, which for the infinite number of bosons transforms into the discontinuity of $c_N(T)$, is an indication of the phase transition to the condensate state. Qualitative and quantitative explanation of these physical phenomena is based on the variation of the energy spectrum by the electric field.

description: A polycrystalline silicon (pc-Si) film is produced by low-temperature LPCVD process on a pc-Si seed
layer. The properties of such film are characterized and compared with the films on a glass substrate and a silicon
wafer. The pc-Si seed layers are fabricated by aluminum-induced crystallization (AIC) process with a
glass/Al/Al2O3/a-Si structure and by followed diluted nitric acid etching and ultrasonic vibration polishing. The
resulted AIC pc-Si seed layer had the average grain size of about 15μm. The pc-Si seed layer is, then, thickened (i.e.
the poly silicon film is deposited on the seed layer) by LPCVD process with 600°C for 5 hours. The deposited pc-Si
film on the seed layer was compared with the deposited pc-Si films on a wafer and a glass substrate without seed
layer formation, respectively. As results, we observed that the quality of the pc-Si film on the seed layer is better than
that on the glass and worse than that on the silicon wafer. But it seems to be that the property of the seed layer could
not much influence on the deposition of the pc-Si films, due to the relatively low temperature LPCVD process.

HOLOTYPE: AMNH 813904, adult female, collected at La Avellana, 13.55N, 90.28W (USBGN, 1965), Santa Rosa, Guatemala, on 18 August 1971, by Robert W. Dickerman on the Virus Bird Project (no. VBP 8942). COMMENTS: In the original description, Dickerman gave the AMNH number of the holotype and included specimens from the ‘‘arid lowlands and interior of Guatemala and adjacent El Salvador.’’ Also included was USNM 352744 from Los Chilamates. Paratypes in AMNH are: AMNH 813903 (VBP 8978), male, 11 August 1971; AMNH 813905 (VBP 8978), female, 10 August 1971; AMNH 813906 (RWD 14367), male, 23 July 1972; AMNH 813907 (RWD 15014), immature female, 4 May 1974; AMNH 813908 (RWD 15092), male, 8 August 1974, all collected at La Avellana by R.W. Dickerman. This subspecies was not mentioned by Byers et al. (1995: 287), and Dickinson (2003: 786) indicated that he had not found an evaluation of the name since it was proposed. Dickerman (1987b: 81) listed this name, but incorrectly cited the AMNH number as 813954; the correct number is AMNH 813904.

description: We investigate the impact of glass substrate materials on the formation of cracks in glass during flash
lamp annealing (FLA) of precursor amorphous silicon (a-Si) films to form μm-order-thick polycrystalline Si (poly-Si)
films as a photovoltaic material. Of several glass materials, alkali-free glass substrates, with a moderate thermal
expansion coefficient () and a relatively high glass transition temperature (Tg), show the best result to suppress crack
formation, whereas quartz and soda lime glass substrates, with much smaller and larger , have seriously large
number of cracks after the formation of flash-lamp-crystallized (FLC) poly-Si films. This indicates that there are two
kinds of crack formation mechanisms: tensile stress from upper films and tensile stress due to the expansion of upper
glass, both of which should be cared for the selection of glass materials. Solar cells fabricated using FLC poly-Si
films on alkali-free glass substrates show better performances and smaller dispersion of solar cell properties than cells
on quartz glass substrates, which also results from the suppression of crack formation.

description: Yolŋu, Aboriginal people from Arnhem Land, Australia are at risk of Machado-Joseph disease, with progressive loss of speech. Yolŋu are interested in developing augmentative and alternative communication (AAC) systems in their own languages. This research aimed to develop a culturally responsive process to explore and create a core vocabulary word list for Yolŋu adults living with the disease for inclusion in AAC system prototypes. A list of 243 Yolŋu words and morphemes was created. In this highly collaborative, mixed methods, participatory action research, Balanda (the Yolŋu word for non-Aboriginal people) and Yolŋu researchers conducted cycles of transcription and analysis of a language sample, with oral group discussions to identify which words to include, omit, or add, based on Yolŋu perceptions of the structure and use of their languages. A Yolŋu metaphor, Gulaka-buma (“Harvesting yams”), was identified by Yolŋu researchers to represent and share the research process and findings. Three key themes were identified that summarize the main cultural and linguistic considerations related to changes made to the core vocabulary. Study findings emphasized the role of language as an expression of culture and identity for Indigenous peoples and the importance of considering cultural and linguistic factors in selecting vocabulary for AAC systems.

description: It has recently been shown, in flat Robertson-Walker geometries, that the dynamics of gravitational actions which are minimally coupled to matter fields leads to the appearance of "attractors" - sets of physical observables on which phase space measures become peaked. These attractors will be examined in the context of inhomogeneous perturbations about the FRW background and in the context of anisotropic Bianchi I systems. We show that maximally expanding solutions are generically attractors, i.e. any measure based on phase-space observables becomes sharply peaked about those solutions which have $P=-ρ$.

description: Texturing the silicon-facing glass surface is crucial for enhancing the light trapping performance and
hence the short-circuit current density of poly-Si thin-film solar cells. The AIT (aluminium-induced texturing)
process is a promising glass texturing method for thin-film solar cells. In this paper, the up-scaling of the AIT process
to pilot line-scale borosilicate glass sheets (30 cm 40 cm) is demonstrated. Poly-Si thin-film solar cells made on
such AIT textured glass sheets show a good lateral uniformity of the optical absorption (non-uniformity less than ± 2.5%).

description: The stability theorem for persistent homology is a central result in topological data analysis. While the original formulation of the result concerns the persistence barcodes of $\mathbb{R}$-valued functions, the result was later cast in a more general algebraic form, in the language of \emph{persistence modules} and \emph{interleavings}. In this paper, we establish an analogue of this algebraic stability theorem for zigzag persistence modules. To do so, we functorially extend each zigzag persistence module to a two-dimensional persistence module, and establish an algebraic stability theorem for these extensions. One part of our argument yields a stability result for free two-dimensional persistence modules. As an application of our main theorem, we strengthen a result of Bauer et al. on the stability of the persistent homology of Reeb graphs. Our main result also yields an alternative proof of the stability theorem for level set persistent homology of Carlsson et al.

temperature gradients along and even throughout the sample. With this technique, steep temperature profiles and different
temperatures at the glass and the Si side of a sample are possible. We have been able to process samples at temperatures of
more than 1160 °C very successfully. Both SPC and RTA processes have been introduced and first results will be shown.

description: Unstructured play on playgrounds is beneficial to children’s development, but children with disabilities are often unable to use playgrounds in the same ways as their peers without disabilities. No research to date has focused exclusively on the playground experiences of children who use augmentative and alternative communication (AAC). Therefore, in this scoping review, information from 10 studies published between 1990 and 2020 that investigated the playground experiences of children with disabilities, including those with limited speech, is synthesized. Included studies used experimental or non-experimental designs and involved the collection of either quantitative or qualitative data. The findings indicate that children with limited speech have diverse playground experiences and can benefit in some of the same ways as children with typical development from playground play but that they encounter barriers to participation that go beyond a lack of physical access. Additional research focusing specifically on understanding the communication experiences of children who use AAC on playgrounds is essential to address the complex issues associated with playground participation, including access to aided AAC systems on the playground. To foster more inclusive playgrounds, accessibility standards must address the unique needs of children with limited speech to support participation and access to communication on the playground.

description: We perform the first self-consistent, time-dependent, multi-group calculations in two dimensions (2D) to address the consequences of using the ray-by-ray+ transport simplification in core-collapse supernova simulations. Such a dimensional reduction is employed by many researchers to facilitate their resource-intensive calculations. Our new code (F{\sc{ornax}}) implements multi-D transport, and can, by zeroing out transverse flux terms, emulate the ray-by-ray+ scheme. Using the same microphysics, initial models, resolution, and code, we compare the results of simulating 12-, 15-, 20-, and 25-M$_{\odot}$ progenitor models using these two transport methods. Our findings call into question the wisdom of the pervasive use of the ray-by-ray+ approach. Employing it leads to maximum post-bounce/pre-explosion shock radii that are almost universally larger by tens of kilometers than those derived using the more accurate scheme, typically leaving the post-bounce matter less bound and artificially more "explodable." In fact, for our 25-M$_{\odot}$ progenitor, the ray-by-ray+ model explodes, while the corresponding multi-D transport model does not. Therefore, in two dimensions the combination of ray-by-ray+ with the axial sloshing hydrodynamics that is a feature of 2D supernova dynamics can result in quantitatively, and perhaps qualitatively, incorrect results.

cross sections. We show that voltage dependent EBIC investigations on the native surface and EBIC measurements at
cross sections are in good agreement.

description: In this paper, Infrared Light Beam Induced Current (IR-LBIC) technique is applied on poly-Si thinfilm
solar cells. The IR LBIC system injects photons with two excitation energies to the sample, either close to or
lower than the Si band gap corresponding to laser wavelengths of 1064 nm and 1300 nm, respectively. Interestingly,
for both wavelengths used in this study an enhanced IR-LBIC signal was observed at the grain boundaries of the
poly-Si layer. Subsequent measurements were performed to determine the influence of photoelectric and thermal
effects caused by the IR lasers. The result of the bias dependence as well as the laser power dependence of the IRLBIC
signal intensity are well in agreement, so that for 1064 nm excitation a dominant photoelectric effect is
observed, whereas for 1300 nm excitation the thermal stimulation dominates. Finally, atomic force microscopy
(AFM) measurements were performed to investigate the possibility of optical effects at the grain boundaries. Here,
light trapping phenomena can be induced, which are even more pronounced in the low-absorbing IR regime of
excitation. Therefore, IR-LBIC is shown to be a sensitive method on light trapping structures in silicon based thinfilm
solar cells.

description: We show that implementations for quantum sensing with exceptional sensitivity and spatial resolution can be made using spin-3/2 semiconductor defect states. We illustrate this using the silicon monovacancy deep center in hexagonal SiC based on our rigorous derivation of this defect's ground state and of its electronic and optical properties. For a single $\textrm{V}_{\textrm{Si}}^-$ defect, we obtain magnetic field sensitivities capable of detecting individual nuclear magnetic moments. We also show that its zero-field splitting has an exceptional strain and temperature sensitivity within the technologically desirable near-infrared window of biological systems. The concepts and sensing schemes developed here are applicable to other point defects with half spin multiplet ($S\geq 3/2$) configuration.

title: Hydrogen bonding and the stability of the polypeptide backbone

description: The tertiary structures of globular proteins are crucial in determining reactivity and specificity as biological catalysts and signalling systems. The rules determining the final fold of a protein are still unknown, but some progress has been made in defining tertiary structure in terms of the secondary structure, the conformation of the polypeptide chain. Perhaps surprisingly, not all of the conformational properties of this backbone are known, and several new approaches to studying these are described. Most studies of peptide structure have focused on hydrogen bonding, and this is used as a starting point for this study. Different descriptions of the hydrogen bond, from geometric rules to ab initio calculations, are considered, and an approach based on analysing contributions of individual polar groups to the potential energy using semi empirical Lennard-Jones calculations is chosen on grounds of accuracy, flexibility, and ease of calculation. Using this approach, it is shown that electrostatic interactions between main chain atoms stabilise the right handed twist found in Beta-strands and similar interactions between main-chain atoms not hydrogen bonded to each other influence the geometries of hydrogen bonds in Alpha-helices and Beta-sheets. A role for water and tertiary hydrogen bonds in determining backbone conformation is suggested. The same technique makes it possible to investigate interatomic repulsions as well as attractions. A detailed analysis of the attractions and repulsions in an idealised polypeptide explains many of the features of helical structures in proteins, and suggests a hitherto unexpected directional helix forming pathway, which is supported by a range of kinetic and structural data. Software for automated searching of a hydrogen bond database is developed, and used to identify hydrogen bonded rings formed by amide side chains and main chain peptides. Integrating the database with novel visualisation techniques allows a previously unidentified property of beta sheets, the hydrophobic ridge, to be detected. A range of different computational approaches was used surging this research, from molecular modelling to database searching. Several pieces of software were developed, and these are described together with some observations about the types of software and working environments which were found to be useful in structural biochemistry, and what types of software technology could be developed to make this task easier.

description: Pursuing the solar PV cost curve calls for continuous cost reduction in cell production. Key factors in
cost-efficient solar cell manufacturing are high operational process reliability and the energy efficiency of processes.
With thin-film PV being a technology still in its infancy, it holds a vast potential for process improvements. The
emergence of CIS / CIGS and the resurrection of amorphous silicon technology are witnesses to this potential.
Several approaches for significantly improving the operational reliability and efficiency in plasma-based PV
manufacturing steps are presented. Furthermore, real-life test results of DC power supplies for magnetron sputtering
and RF power supplies for plasma-enhanced chemical vapor deposition are demonstrated.

description: Tissue engineering requires the precise positioning of mammalian cells and biomaterials on substrate surfaces or in preprocessed scaffolds. Although the development of 2D and 3D bioprinting technologies has made substantial progress in recent years, precise, cell-friendly, easy to use, and fast technologies for selecting and positioning mammalian cells with single cell precision are still in need. A new laser-based bioprinting approach is therefore presented, which allows the selection of individual cells from complex cell mixtures based on morphology or fluorescence and their transfer onto a 2D target substrate or a preprocessed 3D scaffold with single cell precision and high cell viability (93–99% cell survival, depending on cell type and substrate). In addition to precise cell positioning, this approach can also be used for the generation of 3D structures by transferring and depositing multiple hydrogel droplets. By further automating and combining this approach with other 3D printing technologies, such as two-photon stereolithography, it has a high potential of becoming a fast and versatile technology for the 2D and 3D bioprinting of mammalian cells with single cell resolution.

description: Wire shading during thin film deposition is a promising approach to low-cost, high volume
manufacturing of flexible thin film photovoltaic modules. This contribution demonstrates successful patterning of front
and back contacts by wire shading on glass substrates and also during static and dynamic web coating. For static module
manufacturing on glass plates, comparison of the performance of test cells with the performance of solar modules proves
shunt free front and back contact patterning. Continuous sputtering of ZnO:Al on a 30 cm wide polymer foil and simultaneous
wire shading form 1 cm wide and 300 cm long front or back contact stripes for thin film photovoltaic modules.
Analysing the distribution of lateral shunts after separating the initial 28 stripes into 1323 pieces, yields a patterning
success of 97.3 %. Thus the technique allows for roll-to roll manufacturing of flexible photovoltaic modules.

See Hellmayr, 1938: 134, Rothschild and Hartert, 1899: 164, and Dickinson, 2003: 796. HOLOTYPE: AMNH 517834, adult male, collected on Santa Fe (5 Barrington) Island, 00.49S, 90.04W (Paynter, 1993), Galapagos Islands, Ecuador, in July 1891. From the G. Baur Collection (no. 596) via the Rothschild Collection. COMMENTS: In the original description, Ridgway cited Baur’s unique number of the holotype, noting that Baur had collected two adult males and a specimen in streaked plumage. He also gave the collecting date of the holotype as 9 July 1891, but this day does not appear on the labels now present on the specimen. The holotype bears an unnumbered USNM type label with Baur’s number on it, placed there by Ridgway, a Rothschild type label, and a Rothschild Collection label. In addition to the holotype, there are now three Baur specimens in AMNH, ex spirits, all of which are in female or subadult male plumage and without any indication as to which Ridgway may have examined. These possible paratypes are: female, AMNH 517827, and males, AMNH 517837, 517838, all collected in July 1891 on Santa Fe Island.

description: The increasing number and precision of measurements of neutron star masses, radii, and, in the near future, moments of inertia offer the possibility of precisely determining the neutron star equation of state. One way to facilitate the mapping of observables to the equation of state is through a parametrization of the latter. We present here a generic method for optimizing the parametrization of any physically allowed EoS. We use mock equations of state that incorporate physically diverse and extreme behavior to test how well our parametrization reproduces the global properties of the stars, by minimizing the errors in the observables mass, radius, and the moment of inertia. We find that using piecewise polytropes and sampling the EoS with five fiducial densities between ~1-8 times the nuclear saturation density results in optimal errors for the smallest number of parameters. Specifically, it recreates the radii of the assumed EoS to within less than 0.5 km for the extreme mock equations of state and to within less than 0.12 km for 95% of a sample of 42 proposed, physically-motivated equations of state. Such a parametrization is also able to reproduce the maximum mass to within 0.04 M_sun and the moment of inertia of a 1.338 M_sun neutron star to within less than 10% for 95% of the proposed sample of equations of state.

description: The zero to four loop contribution to the cross section $R_{e^{+}e^{-}}$ for $e^{+}e^{-} \longrightarrow$ hadrons, when combined with the renormalization group equation, allows for summation of all leading-log ($LL$), next-to-leading-log $(NLL) \ldots N^3LL$ perturbative contributions. It is also shown how all logarithmic contributions to $R_{e^{+}e^{-}}$ can be summed and that $R_{e^{+}e^{-}}$ can be expressed in terms of the log independent contributions, and once this is done the running coupling $a$ is evaluated at a point independent of the renormalization scale $μ$. All explicit dependence of $R_{e^{+}e^{-}}$ on $μ$ cancels against its implicit dependence on $μ$ through the running coupling $a$ so that the ambiguity associated with the value of $μ$ is shown to disappear. The renormalization scheme dependency of the "summed" cross section $R_{e^{+}e^{-}}$ is examined in three distinct renormalization schemes. In each case, $R_{e^{+}e^{-}}$ is expressible in terms of renormalization scheme independent parameters $τ_i$ and is explicitly and implicitly independent of the renormalization scale $μ$. Two of the forms are then compared graphically both with each other and with the purely perturbative results and the $RG$-summed $N^3LL$ results.

description: In the risk assessment of cascading outages, the rationality of simulation and efficiency of computation are both of great significance. To overcome the drawback of sampling-based methods that huge computation resources are required and the shortcoming of initial contingency selection practices that the dependencies in sequences of outages are omitted, this paper proposes a novel risk assessment approach by searching on Markovian Tree. The Markovian tree model is reformulated from the quasi-dynamic multi-timescale simulation model proposed recently to ensure reasonable modeling and simulation of cascading outages. Then a tree search scheme is established to avoid duplicated simulations on same cascade paths, significantly saving computation time. To accelerate the convergence of risk assessment, a risk estimation index is proposed to guide the search for states with major contributions to the risk, and the risk assessment is realized based on the risk estimation index with a forward tree search and backward update algorithm. The effectiveness of the proposed method is illustrated on a 4-node power system, and its convergence profile as well as efficiency is demonstrated on the RTS-96 test system.
