description: Cylinder type dye sensitized solar cells have an advantage on easy encapsulation over flat type dyesensitized
solar cells. We have already reported transparent conductive oxide-less cylinder dye-sensitized solar cells
(TCO-less cylinder DSC) fabricated inside a glass tube (6.1 % efficiency). We now present TCO-less cylinder DSCs
with flexible structures with 5.1% efficiency (F-DSC). The flexible cell consists of a silicone tube (a supporter of a
counter electrode)(A), stainless steel metal mesh tube covered with thin Ti layer (counter electrode)(B), a gel
electrolyte tube(C), a porous titania layer stained with dyes(E) fabricated on a stainless steel metal mesh tube covered
with thin Ti layer(D), and a plastic tube(F). N719 dye and electrolyte (E-1) consisting of iodine/iodide redox species
were employed in this study. The efficiency was only 3.39% (FF: 0.70; Voc: 0.71 V; Jsc: 6.73 mA/cm2). In order to
reduce a gap between a plastic tube wall and a counter electrode, a thermally shrinkable tube (G) was employed. The
thermally shrinkable tube was shrunk by adding heat at 120°C, which made the gap between an anode and a counter
electrode narrow. After the thermal treatment, the inside diameter of the thermally shrinkable tube (G) was reduced
from 5.5 mm to 4.2 mm, resulting in reducing the gap between two electrodes. The efficiency increased from 3.39%
to 5.08% (FF: 0.68; Voc: 0.68 V; Jsc: 11.07 mA/cm2) after the thermal treatment. It was proved that total electrical
power output of a TCO-less cylinder DSC was 1.3 times higher than that of a TCO-less flat time DSC. This was
explained higher power output in the morning and in the afternoon due to large incident-light angle against cylinder
solar cell surface in the morning and in the afternoon.

description: This study explores similarities and differences in turntaking structures in the discourse of a group of typical children and one atypical child. Nineteen normally developing pre-school children and one atypical child were videotaped reading books with their parents. Each of the nineteen parent/child dyads were videotaped at the child's pre-school, and the atypical child (Ben) was videotaped at school both with a trained educator and with his mother. Analyses of the resulting videotapes yielded categorical data on types and structures of turntaking. The utterances of the typical children appeared most often in the category of response. This finding also applied to Ben when he was interacting with his teacher, although when Ben was interacting with his mother the majority of his utterances appeared in the category of imitation. Parents of the typical children used primarily responses, mands and turnabouts. The greatest difference between Ben's mother and the other parents is found in the categories of response and mand which were lower in the case of Ben's mother. It appears that conversational turntaking in a language delayed child is different from the pattern of conversational turntaking in a group of typical children.

If indeed the difficulty lies with interaction, or turntaking skills, this may have significant implications for approaches to remediation used with children who are identified as autistic or severely learning disabled.

description: The field-effect passivation of Al2O3 films deposited by plasma–assisted atomic layer deposition (PA-ALD) for p- and ntype
c-Si was investigated. The effective surface recombination velocity (Seff) at the PA-ALD Al2O3/Si interface was obtained by
both positive corona charge and lifetime measurements with a gate bias voltage on a metal-oxide-silicon-oxide-metal (MOSOM)
structure. The phenomenon of little drop of Seff with high positive voltage applied on p-type wafer passivated by PA-ALD Al2O3
was observed which is consistent with the slight Seff decrease with long time positive corona charge. Energy dependent capture
cross sections for electrons and holes were calculated simulated for the PA-ALD Al2O3/c-Si interface by a method proposed by K.
Yasutake. It was found that the maximum capture cross section of electrons is approximately 100 times larger than that of holes.
Electron traps exist in PA-ALD Al2O3 layer which is illustrated by observed electron injection phenomenon for both positive and
negative biased MOS structure. The ability of electron injection from silicon to Al2O3 can be controlled by changing Al2O3
deposition parameters.

description: In order to improve the efficiency and reduce the cost of photovoltaic (PV) systems, the use of
transformer-less inverters is an alternative of increasing interest. However this topology needs to be studied in detail,
as the absence of a galvanic isolation between the grid and the PV array leads to some problems, such as DC current
injection and leakage currents. Transformer-less inverters shall comply with leakage current and power quality limits
and reactive power handling capability, which are requested by national grid codes. These stringent requirements
have triggered a race among PV inverters producers and among researchers to find the best possible PV inverter. This
paper aims at benchmarking some recently published or patented topologies with the most successful industrial
products and it offers a complete trends scenario and a critical comparison. The performances are evaluated in terms
of efficiency, common mode voltage, leakage current, power quality, reactive power handling capability, size of the
grid filter and power converter rating.

description: Autonomy in unmanned underwater vehicle (UUV) navigation is critical for most applications due to inability of human operators to control, monitor or intervene in underwater environments. To ensure safe autonomous navigation, verification and validation (V&V) procedures are needed for various applications. This thesis proposes a game theory-based benchmark validation technique for trajectory optimization for non-cooperative UUVs. A quadratically constrained nonlinear program formulation is presented, and a "perfect-information reality" validation framework is derived by finding a Nash equilibrium to various two-player pursuit-evasion games (PEG). A Karush-Kuhn-Tucker (KKT) point to such a game represents a best-case local optimum, given perfect information available to non-cooperative agents. Rolling-horizon foresight with robust obstacles are incorporated to demonstrate incomplete information and stochastic environmental conditions. A MATLAB-GAMS interface is developed to model the rolling-horizon game, and is solved via a mixed complementarity problem (MCP), and illustrative examples show how equilibrium trajectories can serve as benchmarks for more practical real-time path planners.

After combining HCN 1-0, HCO$^{+}$ 1-0 and HNC 1-0 data from literature with our detections, relations between luminosities of dense gas tracers (HCN 1-0, HCO$^{+}$ 1-0 and HNC 1-0) and infrared luminosities are derived, with tight linear correlations for all tracers. Luminosities of CS 3-2 with only our observations also show tight linear correlation with infrared luminosities. No systematic difference is found for tracing dense molecular gas among these tracers. Star formation efficiencies for dense gas with different tracers also do not show any trend along different infrared luminosities. Our study also shows that HCN/HCO$^{+}$ line ratio might not be a good indicator to diagnose obscured AGN in galaxies.

description: We consider a modification of electrodynamics by an additional light massive vector field, interacting with the photon via Chern-Simons-like coupling. This theory predicts observable effects for the experiments studying the propagation of light in an external magnetic field, very similar to those, predicted by theories of axion and axion-like particles. We discuss a possible microscopic origin of this theory from a theory with non-trivial gauge anomaly cancellation between massive and light particles (including, for example, millicharged fermions). Due to the conservation of the gauge current, the production of the new vector field is suppressed at high energies. As a result, this theory can avoid both stellar bounds (which exist for axions) and the bounds from CMB considered recently, allowing for positive results in experiments like ALPS, LIPPS, OSQAR, PVLAS-2, BMV, Q&A, etc.

description: We examine the axion emission from supernovae with a complete set of relevant axion couplings including the axion-pion-nucleon contact interaction which was ignored in the previous studies. Two processes are affected by the axion-pion-nucleon contact interaction, $π^-+p \rightarrow n + a$ and $n+p\rightarrow n+p+a$, and these processes can be the dominant source of axions for some region in the axion parameter space or in astrophysical conditions encountered inside supernovae. We find that the contact interaction can enhance the axion emissivity of $π^-+p \rightarrow n + a$ by a factor of $2-4$, while the effect on $n+p\rightarrow n+p+a$ is not significant. We also discuss the relative importance of other pion-induced processes such as $π^0+n\rightarrow n+a$ and $π^-+π^0\rightarrow π^-+a$.

description: This thesis describes a series of experiments to investigate the effect of thermal stimulation on corticospinal excitability using transcranial magnetic stimulation (TMS). Experiment I showed that innocuous cooling or warming of a single digit, produced short-lasting and mixed patterns of modulation only during actual thermal stimulation, with the inhibition being the most common pattern observed. In line with this finding, cooling stimulation applied to a larger area (i.e. multi-digits) produced variable but more sustained modulation in motor evoked potential (MEP) amplitude in the post-cooling phase (Exp II). Notably, the responses to cooling in terms of either suppressed or enhanced corticospinal excitability tended to be fairly consistent in a given individual with repeated applications. When examining possible sources of the observed variable MEP modulation, we found that individual characteristics such as age, sex and changes in skin temperature had no major influences. We hypothesized that the variability of responses might be related to individual differences in the excitability of intra-cortical circuits involved in sensorimotor integration. To test this hypothesis, we performed Experiment III using conditioning TMS paradigms. This experiment revealed that TMS markers of sensorimotor integration (SAI and SAF levels) were good predictors of individual variations in cooling-induced modulation in corticospinal excitability. This provided evidence supporting the role of SAI and SAF as markers to predict individual’s response to focal thermal stimulation. The identification of such predictors could enhance the therapeutic applicability of this form of stimulation in neurorehabilitation. Collectively, these findings advance our understanding of the neurophysiological basis of thermal stimulation and shed light on the development of a more rational application of neurofacilitation techniques based on afferent stimulation in clinical populations, such as stroke survivors.

description: This paper studies least-squares ReLU neural network method for solving the linear advection-reaction problem with discontinuous solution. The method is a discretization of an equivalent least-squares formulation in the set of neural network functions with the ReLU activation function. The method is capable of approximating the discontinuous interface of the underlying problem automatically through the free hyper-planes of the ReLU neural network and, hence, outperforms mesh-based numerical methods in terms of the number of degrees of freedom. Numerical results of some benchmark test problems show that the method can not only approximate the solution with the least number of parameters, but also avoid the common Gibbs phenomena along the discontinuous interface. Moreover, a three-layer ReLU neural network is necessary and sufficient in order to well approximate a discontinuous solution with an interface in $\mathbb{R}^2$ that is not a straight line.

Mycobank No.: 848859
GenBank Acc. No.: OQ971863 (Partial sequence of SSU rRNA gene).
 Typification: CHINA. Heilongjiang Province: Shuanghe National Nature Reserve, on the surface of the bark of a dead wood, 12 July 2019, collected by Saiyu Wang (Holotype, HMJAU M10070!).
 Diagnosis: The species is similar to L. epidendrum in the sporocarp shapes, but differs in the peridial vesicles, densely and evenly distributed, solitary, rounded, and yellowish-brown.
 Etymology: The epithet “ heterospora ”, refers to the different sizes of spores.
 Description: Sporocarps solitary or in small loose groups, spherical to short horizontally ovoid, regular in shape, 3.5–5.5 mm diam. Peridium membranous, greyish-orange, brownish-orange, covered by vesicles. Peridial vesicles 50–200 μm, in stereomicroscope, look like dried droplets, yellowish-brown, mainly solitary, densely and evenly distributed, distant from each other on ½–1 their diameter, in light microscope solitary, ovoid, light brown. Vesicle walls almost hyaline. Oil droplets absent. Capillitium tubular, 6–15 μm diam, with wavy contours, ornamented by regular bracelet-like thickenings. Spores mass yellowish-gray. Spores vary in size, smaller spores (4.5–)5.0–6.0(–6.5) μm, larger spores (7–)8.0–10.0(–14) μm in diameter, hyaline to pale yellow, marked with a faint reticulation of warts. Immature fructifications unknown.
 Habitat and distribution: On the surface of the bark of a dead wood, currently known only from the type locality, Shuanghe National Natural Reserve in Heilongjiang Province, China.
 Notes: The new species L. heterospora is morphologically similar to L. epidendrum. They have similar sizes and shapes of sporocarps. The peridium is covered with yellowish-brown simple vesicles and it distinguishes this species from the similar L. epidendrum and L. irregulare. The most important characteristic of this species is the spores of varying sizes, smaller spores (4.5–)5.0–6.0(–6.5) μm, larger in diameter (7–)8.0–10.0(–14) μm. For species of the genus Lycogala, spore size is generally in the range of (4.7–)5.5–6.3(–9.5). The spore size difference in one species is less than 4 μm (TABLE 1).

description: A recent paper [arXiv:0801.4566] claims that topologically massive gravity contains only chiral boundary excitations at a particular value of the Chern-Simons coupling. On the other hand, propagating bulk degrees of freedom were found even at the chiral point in [arXiv:0803.3998]. The two references use very different methods, making comparison of their respective claims difficult. In this letter, we use the method of [arXiv:0801.4566] to construct a tower of propagating bulk states satisfying standard AdS boundary conditions. Our states have finite norm, with sign opposite to that of right-moving boundary excitations. Our results thus agree with [arXiv:0803.3998] and disagree with [arXiv:0801.4566].

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1958-1962
description: Aluminum oxide is an excellent candidate for the surface passivation of silicon wafers. Due the
incorporation of a high density of negative charges near the interface surface and a low defect density a very good
passivation can be achieved. Today, aluminum oxide layers are predominantly deposited by atomic layer deposition
and plasma-enhanced chemical vapor deposition. Reactive sputtering is an alternative not requiring
trimethylaluminum. Nevertheless, there are doubts concerning the passivation quality of sputtered aluminum oxide.
In this contribution we analyse the influence of deposition parameters on the properties of the sputtered layers.
Measurements of interface defects density and the density of fixed charges at the interface can explain a good
passivation quality after firing. Additionally, results for LFC-PERC solar cells are presented showing a statistically
significant improve in efficiency compared to standard BSF solar cells. This can be explained by a lower
recombination rate and a higher reflectivity at the rear side of the solar cell.

description: Optical interactions have an important impact on the optical response of nanostructures in complex environments. Accounting for interactions in large ensembles of structures requires computationally demanding numerical calculations. In particular if no periodicity can be exploited, full field simulations can become prohibitively expensive. Here we propose a method for the numerical description of aperiodic assemblies of plasmonic nanostructures. Our approach is based on dressed polarizabilities, which are conventionally very expensive to calculate, a problem which we alleviate using a deep convolutional neural network as surrogate model. We demonstrate that the method offers high accuracy with errors in the order of a percent. In cases where the interactions are predominantly short-range, e.g. for out-of-plane illumination of planar metasurfaces, it can be used to describe aperiodic metasurfaces of basically unlimited size, containing many thousands of unordered plasmonic nanostructures. We furthermore show that the model is capable to spectrally resolve coupling effects. The approach is therefore of highest interest for the field of metasurfaces. It provides significant advantages in applications like homogenization of large aperiodic planar metastructures or the design of sophisticated wavefronts at the micrometer scale, where optical interactions play a crucial role.

description: A PV device described by mean of the parameters Im, Vm, Isc, Voc, Rso and Rsho with certain variability is
chosen in order to evaluate their effect in the prediction of the voltage near short circuit, open circuit and maximum
power. It is encountered that the influence of the parameters Rso and Rsho throughout the whole IV curve is negligible
in comparison with the influence of the rest of parameters. A model to estimate the IV curve of an association of PV
devices using synthetic data generated from measurements of some real samples is developed. The performance of
the model has been tested in one monocrystaline solar panel with 33 cells by measuring the IV curves of the panel
and of each of the 33 cell. The statistical distributions of Isc, Voc and Pm were obtained. Isc, Voc, Im and Vm are linked
by means of a linear relationship. The simulation of the solar panel by the series association of the 33 synthetic cells
supplied a Pm that differs less than 1 % from the measured value.

description: The intermediate band solar cell (IBSC) is a solar cell that, in order to increase its efficiency over that of single gap solar cells, takes advantage of the absorption of below-bandgap energy photons by means of an intermediate band (IB) located in the semiconductor bandgap. For this process to improve the solar cell performance, the belowbandgap photon absorption has to be effective and the IB cannot limit the open-circuit voltage of the cell. In this paper we
provide a guide to the new researcher interested in the idea in order he can quickly become familiar with the concept and updated with the most relevant experimental results.

description: In this third paper of a series on the precision of obtaining ages of stellar populations using the full spectrum fitting technique, we examine the precision of this technique in deriving possible age spreads within a star cluster. We test how well an internal age spread can be resolved as a function of cluster age, population mass fraction, and signal-to-noise (S/N) ratio. For this test, the two ages (Age (SSP1) and Age (SSP2)) are free parameters along with the mass fraction of SSP1. We perform the analysis on 118,800 mock star clusters covering all ages in the range 6.8 < log (age/yr) < 10.2, with mass fractions from 10% to 90% for two age gaps (0.2 dex and 0.5 dex). Random noise is added to the model spectra to achieve S/N ratios between 50 to 100 per wavelength pixel. We find that the mean of the derived Age (SSP1) generally matches the real Age (SSP1) to within 0.1 dex up to ages around log (age/yr) = 9.5. The precision decreases for log (age/yr) > 9.6 for any mass fraction or S/N, due to the similarity of SED shapes for those ages. In terms of the recovery of age spreads, we find that the derived age spreads are often larger than the real ones, especially for log(age/yr) < 8.0 and high mass fractions of SSP1. Increasing the age gap in the mock clusters improves the derived parameters, but Age (SSP2) is still overestimated for the younger ages.

Mark Mosher's reconstruction of the development of the woodworkers union in the Alberni Valley 1935-1950 : a participant's history
Creators: name: McIntosh, Jean Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: This thesis presents a participant's history of the development of the woodworkers' union in the Alberni Valley of British Columbia during the period 1935 to 1950. It is developed through Mosher's own accounts, which are treated as narratives, as the way of most effectively presenting his "insiders point of view". Mosher's interpretation, from his position as a logger, a local union leader, and a Communist Party member, adds to our understanding of the union movement by providing the perspective from the Left and information on the processes of unionization. In spite of the central position held by the union movement in the social structure of British Columbia, and the importance of the IWA within that movement, both have been under researched. Mosher's accounts are given in the context of the documentary history of the union movement and the IWA, and his narratives create a challenging interpretation in response to those established accounts. Comparisons are drawn between the interpretations of the same issues given by Mosher and by the documentary sources. Mosher's accounts express the themes and values important to his alternative history, such as the need for a union and the leadership role of the Communist Party in improving work conditions, which he claims has not before been acknowledged. This thesis is based on the assumption that there is no one true version of history. History is viewed as a process in which differing interpretations continually add to our overall understanding of a subject.

description: The German joint research project “Chemical Gradients in Cu(In,Ga)(S,Se)2” (GRACIS) is an initiative
to gain a better physical understanding concerning the formation of chemical gradients in the Cu(In,Ga)(S,Se)2
(CIGS) absorber layers and at the CIGS/buffer interface. This article presents the current status of the GRACIS
project after three years of execution with results concerning phase formation during chalcogenization and coevaporation
processes, influence of Ga grading on structural and electrical parameters as well as on inhomogeneities
on the μm scale of CIGS. Special features of the CIGS/Zn(O,S) buffer interface are discussed and compared to CIGS
solar cells with CdS buffer. In addition, our experimental results are supported by 3D simulations and calculations
using screened-exchanged hybrid density functional theory.

description: We use very precise frequencies of low-degree solar-oscillation modes measured from 4752 days of data collected by the Birmingham Solar-Oscillations Network (BiSON) to derive seismic information on the solar core. We compare these observations to results from a large Monte Carlo simulation of standard solar models, and use the results to constrain the mean molecular weight of the solar core, and the metallicity of the solar convection zone. We find that only a high value of solar metallicity is consistent with the seismic observations. We can determine the mean molecular weight of the solar core to a very high precision, and, dependent on the sequence of Monte Carlo models used, find that the average mean molecular weight in the inner 20% by radius of the Sun ranges from 0.7209 to 0.7231, with uncertainties of less than 0.5% on each value. Our lowest seismic estimate of solar metallicity is Z=0.0187 and our highest is Z=0.0239, with uncertainties in the range of 12--19%. Our results indicate that the discrepancies between solar models constructed with low metallicity and the helioseismic observations extend to the solar core and thus cannot be attributed to deficiencies in the modeling of the solar convection zone.

description: ECN has developed modules with Metal Wrap Through (MWT) cells glued on a electrical conductive
Back Contact (BC) foil. The properties of the MWT-BC modules and a standard H-pattern module were investigated
by outdoor IV tracing measurements. For both modules, the short circuit current is linear with the irradiance. The
power output of the MWT-BC module is also linear with the irradiance, while the H-pattern module deviates from
linearity at increasing irradiance. The deviation from linearity is explained by the higher series resistance of the
H-pattern module due to the ohmic resistance of the busbars. The gain in yield due to the lower resistance of the
MWT-BC module is calculated from the power output of the out-door IV tracing measurements at ECN (Amsterdam
area, The Netherlands). The gain in yield will be even higher for southern countries and future modules having higher
efficiency and improved light incoupling.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 160-163
description: In this work, we report a novel low-cost approach of fabricating multi-junction (MJ) solar cells based
on a Direct Metal Interconnect (DMI) integration method. In this approach, low resistance contacts between the subcells
are achieved through inner semiconductor-metal-semiconductor contact, eliminating the necessity of using
tunnel junctions. The air gaps between the sub-cells are filled with transparent epoxy with a refractive index of 1.5 in
order to reduce the optical loss at the interfaces. Compared to the traditional monolithic growth approach, DMI
completely eliminates material growth constraints related to the lattice mismatch between two materials. Even subcells
with large lattice mismatch, such as GaAs and Silicon, can be integrated into one MJ solar cell stack without
performance degradation. In combination with the DMI integration, the Areal Current Matching (ACM) technique
has been utilized to achieve current matching between the sub-cells, enabling the maximum 2-terminal efficiency
output from the MJ solar cell. A GaInP/InGaAs/Si triple-junction solar cell has been demonstrated in this work, with
an efficiency of 25.5% at 1-sun AM1.5G. To our knowledge this is a record efficiency for III-V on Si MJ solar cells
in 2-terminal mode.

description: We discuss the effects that a noncommutative geometry induced by a Drinfeld twist has on physical theories. We systematically deform all products and symmetries of the theory. We discuss noncommutative classical mechanics, in particular its deformed Poisson bracket and hence time evolution and symmetries. The twisting is then extended to classical fields, and then to the main interest of this work: quantum fields. This leads to a geometric formulation of quantization on noncommutative spacetime, i.e. we establish a noncommutative correspondence principle from *-Poisson brackets to *-commutators. In particular commutation relations among creation and annihilation operators are deduced.

Temperature dependent striction effect in a single crystalline Nd2Fe14B revealed using a novel high temperature resistivity measurement technique

description: We studied the temperature dependence of resistivity in a single crystalline Nd2Fe14B using a newly developed high temperature probe. This novel probe uses mechanical pin connectors instead of conducting glue/paste. From warming and cooling curves, the Curie temperature was consistently measured around Tc = 580 K. In addition, anomalous discrete jumps were found only in cooling curves between 400 and 500 K, but not shown in warming curves. More interestingly, when the jumps occurred during cooling, the resistivity was increased. This phenomenon can be understood in terms of temperature dependent striction effect induced by the re-orientation of magnetic domains well below the Curie temperature.
Planning Northwest British Columbia economic development : a comparative study
Creators: name: Webber, Andrew J. M.
Publisher: name: University of British Columbia
Year: 2010

description: The thesis is; a retrospective examination of two economic plans and their respective planning processes, undertaken for the same area during the same time period. The geographic setting for the thesis is northwestern British Columbia. The time period covered by the review is approximately 1980 to 1985. The thesis describes the differences which can occur between the two plans and searches for variations in the planning processes which seem to account for these differences. The economic plan produced by the British Columbia provincial government recommends a future regional economy based on large-scale, capital-intensive technology and functional integration of the region with a world economy. The planning process used was centralized and technocratic. The other plan, produced by the regional Economic Development Commission, also recommends functional integration but is oriented towards sustained community development and appropriate (i.e. small-scale, locally-controlled) technology. The plan is informed by a locally-based, participatory process. Categories for comparing the two plans and processes are drawn from regional development planning literature, planning theory literature and review of the cases themselves. Nine planning process variables are employed in the analysis. The study concludes that the critical planning process variables which affect the content of the plans are: the level of public participation in each process, the manner in which control over planning process is centralized or decentralized, and the spatial interest of key actors. The study method used, an ex post facto case study, however, can only infer causal relationships between process and plan variables; it does not provide certain knowledge of these relationships.
