description: The short circuit current (Jsc) of a bulk heterojunction polymer-fullerene solar cells is strictly related to
the absorption of the blend film. Recently it has been show that devices realized using [70]PCBM as electron
acceptor can improve the current output of such device because C70 derivatives have a stronger and broader
absorption compared to C60 ones. Moreover, in devices with ohmic contacts, the open circuit voltage (Voc) is
proportional to the energy difference between the highest occupied molecular orbital (HOMO) of the electron donor
and the lowest unoccupied molecular orbital (LUMO) of the electron acceptor. In addition, for an efficient exciton
dissociation, also the relative position of donor LUMO and acceptor LUMO is crucial. In the present study density
functional molecular orbital calculations are performed on C70 derivatives with the aim to verify if they can be used
as electron acceptors in polymer solar cells. We have investigated if the chemical approaches successfully used in the
last years to tune the LUMO level of C60 derivatives can be applied also for C70 based compounds in order to
maximize the Voc of the corresponding devices and to combine this benefit with the increase of the Jsc arising from
the improved absorption.

description: This work reports a comparison between two methods used for ZnO nanowires growth with the goal to
perform DSSCs. Structural and crystalline characterizations show well aligned and dense nanowires with defect free
crystalline structure in case of CBD whereas MOCVD leads to a low density and bush like structure with crystalline
defects. MOCVD cells IV-curves show lower short circuit current than CBD cells. This is mainly due to the low
specific density of MOCVD deposit, which gives poor LHE. A worse injection efficiency between dye and ZnO is
also another contribution of the low short circuit current of MOCVD derived cells. However cell derived from
MOCVD shows a ten times faster transport time constant.

description: In the context of energy-efficient building the use of solar energy in and at buildings is a central topic . Solar
thermal and photovoltaic systems open a multiplicity of application possibilities and offer qualitatively high-quality products.
To increase acceptance and to foster awareness of this topic, the Bavarian Association for the Promotion of Solar Energy
has organized the competition “Building-Integrated Solar Technology 2008”. 40 projects were entered, 38 projects from
8 countries were assessed by the jury. The jury - Chairman: Prof. Thomas Herzog - awarded two main prizes, three commendations
and five citations. The competition entries show the huge potential of coherent integrated solar technology as a
part of advanced architectural and energy technical building concepts. However, architects and engineers consider the results
from different viewpoints. It is demonstrated that architects and engineers together can find best solutions, which do not
only comprise photovoltaics, but a wide range of renewable technologies.

description: Most systematic tables of data associated to ranks of elliptic curves order the curves by conductor. Recent developments, led by work of Bhargava-Shankar studying the average sizes of $n$-Selmer groups, have given new upper bounds on the average algebraic rank in families of elliptic curves over $\mathbb{Q}$ ordered by height. We describe databases of elliptic curves over $\mathbb{Q}$ ordered by height in which we compute ranks and $2$-Selmer group sizes, the distributions of which may also be compared to these theoretical results. A striking new phenomenon observed in these databases is that the average rank eventually decreases as height increases.

description: While the dominant magnetic interaction in La$_2$CuO$_4$ is superexchange between nearest-neighbor Cu moments, the pinning of the spin direction depends on weak anisotropic effects associated with spin-orbit coupling. The symmetry of the octahedral tilt pattern allows an out-of-plane canting of the Cu spins, which is compensated by an opposite canting in nearest-neighbor layers. A strong magnetic field applied perpendicular to the planes can alter the spin canting pattern to induce a weak ferromagnetic phase. In light of recent evidence that the lattice symmetry is lower than originally assumed, we take a new look at the nature of the field-induced spin-rotation transition. Comparing low-temperature neutron diffraction intensities for several magnetic Bragg peaks measured in fields of 0 and 14 T, we find that a better fit is provided by a model in which spins rotate within both neighboring planes but by different amounts, resulting in a noncollinear configuration. This model allows a more consistent relationship between lattice symmetry and spin orientation at all Cu sites.

description: In the previous study [12] the computer algorithm developed for analyzing impurity profiles in
semiconductor devices, utilized a numerical approach based on the integration of experimentally obtained C–V data.
As a follow-up, the same algorithm is applied for energy barrier calculations for Si p-i-n solar cells in darkness. The
algorithm allows us to assess the impurity profile across the device, which in turn enables us to estimate built-in
potential values, Vbi, more accurately. Using plots of accurately estimated Vbi values together with Voc values as a
function of temperature, a current conduction mechanism model across devices being tested can be suggested.
For Si p-i-n, it is observed that built-in potential in darkness increases linearly with decreasing temperature
from 330K down to 50 K. In this region Vbi versus T has the slope of 2.54 10-3 Volt/K. When the energy barrier
under illumination is measured as a function of temperature, the Voc versus T exhibited a linear behavior with a slope
of 2.03 10-3 Volt/K. These two lines converged at about 50 K. Below 50 K both curves show less temperature
sensitivity. At this point, it is assumed that p-i-n structure reaches the flat band condition. The data generated using
the algorithm from experimental results for the Vbi-T and the measured Voc-T match closely with the theoretical
calculations for SRH recombination in the SCR [22].

description: Compartmental models based on tracer mass balance are extensively used in clinical and pre-clinical nuclear medicine in order to obtain quantitative information on tracer metabolism in the biological tissue. This paper is the first of a series of two that deal with the problem of tracer coefficient estimation via compartmental modelling in an inverse problem framework. Specifically, here we discuss the identifiability problem for a general n-dimension compartmental system and provide uniqueness results in the case of two-compartment and three-compartment compartmental models. The second paper will utilize this framework in order to show how non-linear regularization schemes can be applied to obtain numerical estimates of the tracer coefficients in the case of nuclear medicine data corresponding to brain, liver and kidney physiology.

The data given match the label information on AMNH 696435, his only specimen from Launceston. I consider it the holotype. Ashby’s label is still present but has faded almost to illegibility; however, the date 17 June 1905 is still readable. Mathews collection label with his catalog number and a Rothschild Museum label printed ‘‘Ex. Coll. G.M. Mathews’’ are also present. The specimen had not previously been included in the AMNH type collection.

description: Two-dimensional microparticle crystals can be formed in the sheath of a gas discharge plasma. Ions from the bulk plasma are accelerated in the sheath electric field, flowing past the grains to create a positive ion wake downstream from the grains. Interaction between the ion wake and neighboring grains creates additional coupling between oscillation modes and can trigger mode-coupling instability (MCI). Recent experiments have shown that at a fixed discharge power there are threshold pressures above and below which the monolayer always crystallizes or melts, respectively. The melting is due to MCI being triggered in the crystal monolayer, while the crystallization is due to the suppression of MCI by neutral damping in the fluid monolayer. The relationship between the discharge parameters and ion wake characteristics is unknown. A molecular dynamics simulation of ion dynamics and dust charging is used to self-consistently determine the dust charge and ion wake characteristics for different experimental conditions. It is found that the ion wake is strongly dependent on discharge pressure but not affected much by the discharge power.

description: In this paper, we present a highly efficient ultra-thin multi-crystalline silicon (mc-Si) solar cell with novel anti-reflection coatings. For improving the efficiency, new anti-reflection coatings and aluminum paste for screen printing were developed. The anti-reflection coatings were deposited from a dispersion of colloidal MgF2 and ZrO2 onto accomplished solar cells. The morphology of the particulate film was changed by deposition method, contributing the change of the refractive index. The reflection spectra of the solar cells after coating of the particulate
films were successfully lowered with respect to those before depositions. As the result, short circuit current of the solar cells were improved. Together with the anti-reflection coatings, new aluminum paste for screen printing for rear electrode was utilized for ultra-thin mc-Si wafers. As the result, 17.4% in conversion efficiency was achieved with 100-m-thick mc-Si wafer in industrial size of 15 cm x 15 cm was achieved.

Using extensive numerical simulations of several model glasses in three dimensions, we show that in systems of linear size $L$ sufficiently smaller than a crossover size $L_{D}$, the low-frequency tail of the density of states follows $D(ω)\!\sim\!ω^4$ up to the vicinity of the lowest Goldstone mode frequency.

HOLOTYPE: AMNH 693983, adult male, collected at Umawera, ca. 35.17S, 173.35E, Hokianga Harbour, North Island, New Zealand, in October 1907, by Robin Kemp. From the Mathews Collection via the Rothschild Collection. COMMENTS: In the original description, Kemp gave the collecting locality and wing measurement (150 mm) of the type and said that it was in his possession. Hartert (1928: 204) listed this specimen as the type and noted that two Kemp specimens had come to the Rothschild Collection [with the Mathews Collection] with very different measurements and that only the type had an exact locality. Both of those specimens are now in AMNH and my measurements are almost the same as those of Hartert: 150 mm for the holotype and 142 mm for the unsexed specimen. The unsexed specimen has no original label and no exact locality, and there is no indication on Mathews’ label that he obtained it from Kemp; therefore, I do not consider that it has type status. The holotype bears Kemp’s original label, a Mathews type label with reference to Kemp’s description, and a Rothschild type label. I did not find it listed in Mathews’ catalog.

For general $Γ$ we establish (under rather mild hypotheses) a lower bound involving the dimension of the Patterson-Sullivan measure along boundaries of complex geodesics. Our main tool is a version of the celebrated Ledrappier-Young theorem.

description: It is well known that the recombination of excess carriers at semiconductor surfaces can be
substantially reduced by electrostatic charge. The ability to incorporate large charge densities in dielectric films, and
to vary the charge density through adjustment of deposition parameters or post deposition treatments, raises an
important practical question: how much charge is enough for optimum passivation? We attempt to answer this
question through direct measurement of the emitter saturation current density Joe as a function of applied voltage on
samples with a symmetric metal-insulator-semiconductor (MIS) structure. Our results indicate that the impact of
applied charge density on surface recombination tends to saturate at charge densities of around 8x10-7C/cm-2 (5x1012
charges cm-2), so that higher charge densities do not offer any increased benefit for surface passivation. While our
results are currently confined chiefly to oxide passivated samples, we expect that a similar behavior will be observed
for samples passivated with other dielectric films.

description: We report the successful production of an ultracold sample of absolute ground-state $^{23}$Na$^{87}$Rb molecules. Starting from weakly-bound Feshbach molecules formed via magneto-association, the lowest rovibrational and hyperfine level of the electronic ground state is populated following a high efficiency and high resolution two-photon Raman process. The high purity absolute ground-state samples have up to 8000 molecules and densities of over $10^{11}$ cm$^{-3}$. By measuring the Stark shifts induced by external electric fields, we determined the permanent electric dipole moment of the absolute ground-state $^{23}$Na$^{87}$Rb and demonstrated the capability of inducing an effective dipole moment over one Debye. Bimolecular reaction between ground-state $^{23}$Na$^{87}$Rb molecules is endothermic, but we still observed a rather fast decay of the molecular sample. Our results pave the way toward investigation of ultracold molecular collisions in a fully controlled manner, and possibly to quantum gases of ultracold bosonic molecules with strong dipolar interactions.

description: The influence of atomic hydrogen on the surface passivation of the Si-SiO2 interface is investigated. Inductively
coupled photoconductivity decay measurements indicate an increase in carrier recombination at the surfaces following atomic
hydrogen exposure, as measured by an increase in the emitter saturation current density. These defects are not thermally
stable and are removed by subsequent thermal treatments at 300oC in N2. In addition, atomic hydrogen results in the
passivation of a certain fraction of thermally stable interface defects. However, the passivation obtained using atomic
hydrogen has always been observed to be, at best, equal to, the passivation obtained with molecular hydrogen.

description: We present a theoretical study of low temperature nonequilibrium transport through an interacting quantum dot in the presence of Zeeman magnetic field and current injection into one of its leads. By using a self-consistent renormalized equation of motion approach, we show that the injection of a spin-polarized current leads to a modulation of the Zeeman splitting of the Kondo peak in the differential conductance. We find that an appropriate amount of spin accumulation in the lead can restore the Kondo peak by compensating the splitting due to magnetic field. By contrast when the injected current is spin-unpolarized, we establish that both Zeeman-split Kondo peaks are equally shifted and the splitting remains unchanged. Our results quantitatively explain the experimental findings reported in KOBAYASHI T. et al., Phys. Rev. Lett. 104, 036804 (2010). These features could be nicely exploited for the control and manipulation of spin in nanoelectronic and spintronic devices.

description: Cost reduction and the enhancement of the solar cell efficiency are in the main focus with economic
relevance for the production of multicrystalline silicon (mc-Si) solar cells. An important issue, due to the recombination
activity of extended defects in the silicon lattice, are the dislocations. We have investigated two different mc-Si
materials which were intentionally doped with germanium in concentrations of 0.5 % to 2 % of weight. An influence
of the germanium on the distribution of oxygen, carbon and the dislocations could be observed for the investigated
material. We found a calibration factor for the determination of the carbon concentration using the Fourier transform
infrared spectroscopy (FTIR) absorption signal of carbon at 1206 cm-1. The germanium distribution was studied as
well along and perpendicular to the growth direction of the crystallisation using wavelength dispersive X-ray spectroscopy
(WDX) and FTIR spectroscopy. The electronic properties of the as-grown material and the processed solar
cells were finally studied showing different behaviour. It turns out that the quality of germanium-doped mc-Si is a
matter of various factors and can not be related only to the dislocations.

description: The sizing of photovoltaic water pumping systems is critical to ensure that the desired amount of water
will be supplied. Therefore, the models used for the sizing of the water pumping systems need to be accurate and suitable
for the system being designed. In order to determine the suitability of the water pumping system sizing, a laboratorybased
testing system was developed to test the accuracy of four water pumping system sizing methods. The laboratory
testing system used was capable of testing water pumping systems from a constant head height of 30 m to 120 m, and
flow rates up to 1.5 m3/hour, under varying irradiation conditions. Although agreement was found between the different
models and experimental results under sunny conditions, a large difference in predicted volume of water was found for
cloudy periods. Additionally, some of the modeling of the pumping sub-system tested was determined to be erroneous
for two of the sizing methods tested, resulting in an overestimation of the maximum flow rates.

description: The review presents an analysis and generalization of classical and most modern approaches to the description and development of operation of open optical nanoresonators, that is, resonators all sizes of which are smaller than the resonant wavelength of radiation in a vacuum. Particular attention is paid to the physics of such phenomena as bound states in a continuum, anapole states, supercavity modes, and perfect nonradiating modes with extremely high quality factors and localizations of electromagnetic fields. An analysis of the optical properties of natural oscillations in nanoresonators made of metamaterials is also presented in the review. The effects considered in this review, besides being of fundamental import can also find applications in the development of optical nanoantennas, nanolasers, biosensors, photovoltaic devices, and nonlinear nanophotonics.

description: Phosphorus gettering and hydrogenation from silicon nitride films have been applied to improve the carrier lifetime and diffusion length in n-type multicrystalline silicon wafers. This allows an assessment of whether the material is suitable for high efficiency, large area solar cells with a rear junction. Extended gettering recipes, in which the samples are held at a moderate temperature (in this case 600C) for several hours during the cooling down after phosphorus diffusion, were found to yield improved lifetimes over standard gettering recipes. Coupled with hydrogenation from silicon nitride films fired at 700C, sufficiently long minority carrier diffusion lengths were achieved in most regions of the wafers. Nevertheless, some regions remained poor enough to reduce the potential performance of rear junction cells on this material. We conclude that front junction devices are probably necessary to achieve high efficiency with such wafers.

description: Absorption enhancement of ultra-thin amorphous silicon (aSi) layers is demonstrated both theoretically
and experimentally, through photonic crystal patterning of the absorbing layer. We show through simulation that an
increase of the absorption by a factor of 1.5 is expected for a demonstrator of 100nm of aSi. The proposal is then
validated by an experimental demonstration, showing a 50% relative increase of the absorption of 100nm of aSi
deposited on glass, holographically lithographed and dry-etched in order to fabricate a one-dimensional photonic
crystal. This shows new possibilities of increasing the efficiency of thin film photovoltaic cells. Photonic crystal
based architecture of thin film cells are proposed and discussed.

description: Der Plötzliche Herztod ist eine der häufigsten Todesursachen in Europa, in den USA sogar die häufigste Ursache aller natürlichen Todesfälle. Ziel der experimentellen und klinischen Forschung ist das Erkennen und Verhindern ("Prediction and Prevention") der malignen Herzrhythmusstörungen. Schwerpunkt der wissenschaftlichen Arbeit bilden die experimentellen Untersuchungen hinsichtlich der Mechanismen von Herzrhythmusstörungen. Durch die Entwicklung neuartiger Mappingsysteme konnte erstmalig gezeigt werden, dass im Tiermodell Kammerflimmern initial fokal und geordnet entsteht. Die bisherigen Untersuchungen und Daten erweitern unser Wissen zur kardialen Defibrillation und zum Entstehen von malignen Herzrhythmusstörungen, stellen aber nur einen Baustein im Gesamtverständnis des Plötzlichen Herztodes dar. Weitere begonnene oder geplante Projekte beschäftigen sich mit Herzrhythmusstörungen bei Vorliegen einer Kardiomyopathie und akuter Ischämie, sowohl im Tiermodell als auch beim Patienten. Neuartige Mappingtechnologien und Tiermodelle können helfen, die Mechanismen zu verstehen, die Therapie von Herzrhythmusstörungen zu verbessern und Therapieverfahren weiterzuentwickeln.
description: Sudden cardiac death is one of the leading causes of death in Europe, and the leading cause of all natural deaths in the USA. The primary aim of experimental and clinical research is the "prediction and prevention" of lethal ventricular arrhythmias. The focus of this thesis is on animal studies investigating the mechanisms of arrhythmias. Using a novel multichannel electrical cardiac mapping technique we were able to demonstrate that whatever generates fibrillation activations it locates at a small region in the LV apex. This research will widen our understanding of defibrillation and causes of lethal ventricular arrhythmias, but is still only a piece of the puzzle called sudden cardiac death. New initiated or planed project are focusing on arrhythmias in patients and animals with heart failure or acute ischemia. Novel mapping techniques and animal models might further widen our understanding of the mechanisms and might help to develop and improve therapeutic options.
Spatial Dispersal of Bacterial Colonies Induces a Dynamical Transition From Local to Global Quorum Sensing

description: Bacteria communicate using external chemical signals called autoinducers (AI) in a process known as quorum sensing (QS). QS efficiency is reduced by both limitations of AI diffusion and potential interference from neighboring strains. There is thus a need for predictive theories of how spatial community structure shapes information processing in complex microbial ecosystems. As a step in this direction, we apply a reaction-diffusion model to study autoinducer signaling dynamics in a single-species community as a function of the spatial distribution of colonies in the system. We predict a dynamical transition between a local quorum sensing (LQS) regime, with the AI signaling dynamics primarily controlled by the local population densities of individual colonies, and a global quorum sensing (GQS) regime, with the dynamics being dependent on collective inter-colony diffusive interactions. The crossover between LQS to GQS is intimately connected to a tradeoff between the signaling network's latency, or speed of activation, and its throughput, or the total spatial range over which all the components of the system communicate.

description: This paper presents a concept of control strategies for PV hybrid system. The paper shows the components’
characteristic of the hybrid system and proposes a solution for controlling of PV hybrid system for powering electricity in
remote area. The control strategies are very important for the design and the implementation of the hybrid system, missing of
proper control strategies leads to improper design and therefore the hybrid system cannot be used for sustainable energy unit.
The paper also presents the main important aspects for control strategies for the design of PV hybrid system.

Our main focus will be on the collective excitations of the dense matter in the presence of an external magnetic field. Constraining the defect field theory to 2+1 dimensions, we will also allow the gauge fields become dynamical and study the properties of a strongly coupled anyonic fluid. We will deduce the universal properties of holographic matter and find that the Einstein relation always holds.

description: Nepal, home to the Mount Everest is with the landscape of the world’s highest peak to the planes just at the
elevation of 60 meters. With such an extreme topographical change within the short span, Nepal has lots of mountains and
hills where thousands of villages and cities are scattered. With difficult terrain in the high hills and with dispersed settlement,
development leading infrastructure construction is not an easy job for the country.
With a potential to generate 83,000 M Watt of hydro electricity, Nepal has yet produced only about 600 M watts. Over 2
million households in Nepal still lack access to electricity and use kerosene-based wick lamps (Tuki in the local language)
and tree resin lamps ( Jharro in the local language) for household lighting. These tukis and Jharro pose a fire hazard and the
fumes (each kerosene tuki gives off about 250 kg of carbon dioxide every year and even more by a Jharro) harm people’s
eyes and lungs and contribute to global warming. Moreover, the tuki use kerosene, which has to be imported and is expensive
or unavailable in rural areas.
To address the energy need in rural Nepal for house hold lighting, Solar PV technology along with the least power
consuming WLED based lights are being promoted by different sectors such that the wick lamps in the rural could be
replaced by these WLED lamps. With 300 sunny days a year solar PV based systems has been considered to be the best
solution for energizing the rural Nepal.
