description: Our article is devoted to the study of the rare $B_s\to ϕ\ell^+\ell^-$ decay where $\ell=μ,τ$. We compute the relevant form factors in the framework of the covariant quark model with infrared confinement in the full kinematical momentum transfer region. The calculated form factors are used to evaluate branching fractions and polarization observables in the cascade decay $B\to ϕ(\to K^+K^-)\ell^+\ell^-$. We compare the obtained results with available experimental data and the results from other theoretical approaches.

description: Technological advances have enabled multiple countries to consider implementing Smart City Infrastructure to provide in-depth insights into different data points and enhance the lives of citizens. Unfortunately, these new technological implementations also entice adversaries and cybercriminals to execute cyber-attacks and commit criminal acts on these modern infrastructures. Given the borderless nature of cyber attacks, varying levels of understanding of smart city infrastructure and ongoing investigation workloads, law enforcement agencies and investigators would be hard-pressed to respond to these kinds of cybercrime. Without an investigative capability by investigators, these smart infrastructures could become new targets favored by cybercriminals. To address the challenges faced by investigators, we propose a common definition of smart city infrastructure. Based on the definition, we utilize the STRIDE threat modeling methodology and the Microsoft Threat Modeling Tool to identify threats present in the infrastructure and create a threat model which can be further customized or extended by interested parties. Next, we map offences, possible evidence sources and types of threats identified to help investigators understand what crimes could have been committed and what evidence would be required in their investigation work. Finally, noting that Smart City Infrastructure investigations would be a global multi-faceted challenge, we discuss technical and legal opportunities in digital forensics on Smart City Infrastructure.

description: The network research project SolarFocus is a joint venture of twelve German research institutes and twelve German PV companies working on silicon for solar cell processing. The project focuses on the three major aspects defect analysis, the study of intentionally contaminated material and new gettering and passivation schemes for industrial application. In the first part actual industrial silicon material for solar cell processing is investigated by the combination of various measurement methods available at the research institutes. In the second part of the work intentionally contaminated material is grown in order to study the effect of single and multiple impurities in silicon block material added in a defined way to standard silicon feedstock. For this investigation small mc-Si crystals have been grown in an experimental furnace with a defined amount of pure metallic iron and copper added to the feedstock in order to reach a concentration of 1017 cm-3 iron and 1018 cm-3 copper in the silicon melt. First lifetime measurements show the expected reduction. Solar cell processing will be carried out and the analysis presented later. In a third part new aspects for gettering and passivation processes on industrial material as well as experimental material are investigated.

description: Food texture influences child feeding through foods that parents decide to introduce to their children, when foods are introduced, and feeding practices used to encourage successful eating of food. This body of work presents four studies that explored the influence of food texture on child feeding, and the parent-child relationship during feeding of two groups of children, children typically developing (CTD), and children diagnosed with Down syndrome (CWDS), with/without food texture sensitivities. The first study explored food texture experiences of CTD and developed a food texture progression map to be used as a benchmark to compare food texture experiences of clinical populations. An increase in age influenced the type of food textures introduced, managed, and rejected among CTD. The second and third studies utilized video coding data from a texture acceptance home-use test of variously textured solid snack foods for both CWDS and CTD. Using a coding scheme, parent behaviours were captured during feeding of these two groups. The second study explored the parent-CWDS relationship during feeding with observations. Parents of CWDS used more supportive than controlling practices to encourage feeding. The third study explored the differences between survey responses to parent feeding behaviour questions and observed parent behaviours captured from the coding scheme for CWDS and CTD. Parents of CWDS reported using controlling behaviours more frequently than supportive behaviours, however coded observations were inconsistent with this survey report.
description: Furthermore, the fourth study expanded on the captured behaviours from the coding scheme to propose a summarization of overall feeding experiences given to CWDS and CTD. Over 90% of parents from both groups provided their children with positive feeding experiences, using supportive practices more than controlling practices. These studies provided meaningful insight into the feeding environment and food texture experiences in child feeding. These studies also expanded upon TS and its influence on child feeding and parent feeding behaviours. Results from the present work conducted in this area may optimize successful feeding in young children, increase quality of life, and provide guidance to parents and practitioners of children with TS.

description: 6” sc-Si and mc-Si black silicon solar wafers with nanoscale surface texturing were fabricated by wet chemical etching within 5 minutes. The overall hemispherical reflectivity of the sc-Si and mc-Si black silicon solar wafers is 1 % and 5 % at wavelengths ranging from 400 nm to 1000 nm, respectively. The black silicon solar wafers can be passivated by thermal oxidation and PECVD Si3N4. The effective life time of a sc-Si black silicon solar wafer passivated by thermal oxidation in a conventional furnace tube at 900oC for 30 minutes is more than 19 μs, which is high enough for a solar cell with thickness less than 200 μm. The sc-Si and mc-Si black silicon solar wafers enable fast and large-scale production of high efficiency solar cells.

description: Hot carrier solar cell (HCSC) may be a solution to overtake the Schockley-Queisser limit for solar cell
efficiency. Models for hot carrier solar cell efficiency simulation have been proposed for HCSC where carrier
thermalization is neglected, giving efficiency up to 86%. Partial carrier thermalization is included here with results
showing efficiencies lower than in the ideal case. This new model as input the thermalization rates that are extracted
from continuous wave photoluminescence experimentsas a function of pump power. These characteristics are used to
evaluate the potential efficiency of realistic cells, showing predicted maximal efficiency reaching 60% for our best
sample.

description: The advantage of LED lighting is its low energy requirement: consumption of indoor lighting by LED
on an annual basis can easily meet the energy produced by PV. Our aim is to develop a “sustainable symbiotic
organism” which can produce its energy need for lighting and is balanced with the user’s lighting wishes. We will
apply an innovative approach by IDE (industrial design engineering), by considering the synergy of LED/PV for a
lighting system. The LED/PV lamp is a standalone system, thought of as a spin-off product for present or future offgrid
markets in Europe: particularly referring to the idea of energetic micro-grids at the urban scale, every building
being a self-sustaining organism. This scenario can be defined as an “urban ecosystem”. In this likely future urban
ecosystem, self-sustaining socket-products (such as an LED/PV lamp) are part and parcel of the micro-grid. The
results of our project are a quantified energy balance calculation and an autonomous lighting product that combines
LED and PV technology.

description: To scavenge energy out of the environment, it is very important for solar cells to maintain the efficiency at low light intensity levels. In this paper, it is experimentally and theoretically shown that n-type base cells outperform p-type base cells at such low injection levels. The high efficiency p-type front junction (18.3% at 1 sun AM1.5) and n-type rear junction (17.7% at 1 sun AM1.5) cells are prepared using an identical cell process based on firing an aluminum paste on the rear. The Al paste acts either as back surface field or rear emitter respectively. Various diffusion conditions results in different emitter (front surface field) for p-type (n-type) cells. Shallower emitter (FSF) for p-type (n-type) cells shows better cell performances. Up to 12.7% under 0.01 Sun and 8% under 0.001 Sun n-type cells were obtained. A detailed characterization of these cells under low illumination conditions was carried out based on the measured efficiency and suns-Voc. The observed dependence of the performance on the injection level is explained using the Shockley-Read-Hall recombination model where the different capture cross sections for electrons and holes has a decisive influence on the minority carrier bulk lifetime for p-type silicon under low level injection.

description: Tunneling in quantum field theory is worth understanding properly, not least because it controls the long term fate of our universe. There are however, a number of features of tunneling rate calculations which lack a desirable transparency, such as the necessity of analytic continuation, the appropriateness of using an effective instead of classical potential, and the sensitivity to short-distance physics. This paper attempts to review in pedagogical detail the physical origin of tunneling and its connection to the path integral. Both the traditional potential-deformation method and a recent more direct propagator-based method are discussed. Some new insights from using approximate semi-classical solutions are presented. In addition, we explore the sensitivity of the lifetime of our universe to short distance physics, such as quantum gravity, emphasizing a number of important subtleties.

description: According to the general-relativistic no-hair theorem, astrophysical black holes depend only on their masses and spins and are uniquely described by the Kerr metric. Mass and spin are the first two multipole moments of the Kerr spacetime and completely determine all other moments. The no-hair theorem can be tested by measuring potential deviations from the Kerr metric which alter such higher-order moments. In this review, I discuss tests of the no-hair theorem with current and future observations of such black holes across the electromagnetic spectrum, focusing on near-infrared observations of the supermassive black hole at the Galactic center, pulsar-timing and very-long baseline interferometric observations, as well as X-ray observations of fluorescent iron lines, thermal continuum spectra, variability, and polarization.

performance results since the completion of the building in December 2007. According to the national policy of
energy conservation and energy efficiency, 642 sq.m. BIPV modules, with amorphous solar cell embedded within the
structural glazing unitized system, are installed on the east-facing façade of 20-story office building. This can be
claimed the first ever BIPV façade in Thailand. The system consists of 428 modules in nine parallel arrays which
each arrays connected with one inverter unit. Together with no battery used, the electricity generated is connected
directly to the main power supply. The module efficiency is 5.2 % with an overall system efficiency of 4.3 %. After
12 months of operation, the system has generated 21,526 kWh and the average electricity generated per month is
1,793.83 kWh. With the results shown, all the components and the overall system have worked effectively. However,
to improve BIPV system, a favorable tilt angle of the system, regarding to the architectural applications, and solar
cell technologies used within the modules would be much concerned. This paper also presents the pros and cons of
the design, testing and installation of BIPV system which can be used, as a guideline, for the new commercial
buildings in Thailand.

A simple graphical interface allows one to browse a chain of many variables quickly, and make publication quality plots of, inter alia, one- and two-dimensional profile likelihood, posterior pdf (with kernel density estimation), confidence intervals and credible regions. In this short manual, we document installation and basic usage, and define all statistical quantities and conventions. The code is fully compatible with Linux, Windows and Mac OSX. Furthermore, if preferred, all functionality is available through the command line rather than a graphical interface.

description: Temperature and injection-dependent lifetime measurements of the effective excess carrier lifetime of crystalline silicon enable the determination of characteristic defect parameters like the energetic defect level and the ratio of the capture cross sections of electrons and holes. Since the effect of temperature-dependent photon reabsorption on quasi-steady-state photoluminescence lifetime measurements can be accounted for, this method is well suited to provide data for the spectroscopic analysis of defects in crystalline silicon. In contradiction to other techniques to determine the injection-dependent lifetime like photoconductance measurements, quasi-steady-state photoluminescence stands out for the robustness against parasitic artifacts like depletion region modulation and trapping, which makes it an ideal tool for the purposes of defect spectroscopy. In this work the capability and reproducibility of the determination of defect parameters of titanium contaminated crystalline silicon samples with different doping and defect concentrations will be shown and results will be presented.

description: Si/SiO2 multiple quantum wells (QWs) embedded in lateral solar cells are reported. The QWs are
fabricated by remote plasma enhanced chemical vapor deposition and are partially recrystallized by subsequent rapid
thermal annealing. Extraction of photogenerated charge carriers parallel to the Si/SiO2 interface is investigated.
Carrier transport is hampered by the incomplete recrystallization. Open circuit voltage increases with decreasing Si
layer thickness, which is caused by a distinct quantum confinement effect within the two-dimensional Si layers.
Compared to the conventional QW solar cell concept, where carrier extraction is severely limited by tunneling
transport through the insulating SiO2 barrier layers, the fundamental conflict between confinement and transport can
be overcome in this new lateral solar cell concept.

description: Could new physics break the mirror symmetry of the Universe? Utilizing recent measurements of the parity-odd four-point correlation function of BOSS galaxies, we probe the physics of inflation by placing constraints on the amplitude of a number of parity-violating models. Within canonical models of (single-field, slow-roll) inflation, no parity-asymmetry can occur; however, it has recently been shown that breaking of the standard assumptions can lead to parity violation within the Effective Field Theory of Inflation (EFTI). In particular, we consider the Ghost Condensate and Cosmological Collider scenarios -- the former for the leading and subleading operators in the EFTI and the latter for different values of mass and speed of an exchanged spin-$1$ particle -- for a total of $18$ models. Each instance yields a definite prediction for the inflationary trispectrum, which we convert to a late-time galaxy correlator prediction (through a highly non-trivial calculation) and constrain using the observed data. We find no evidence for inflationary parity-violation (with each of the $18$ models having significances below $2σ$), and place the first constraints on the relevant coupling strengths, at a level comparable with the theoretical perturbativity bounds. This is also the first time Cosmological Collider signatures have directly been searched for in observational data. We further show that possible secondary parity-violating signatures in galaxy clustering can be systematically described within the Effective Field Theory of Large-Scale Structure. We argue that these late-time contributions are subdominant compared to the primordial parity-odd signal for a vast region of parameter space. In summary, the results of this paper disfavor the notion that the recent hints of parity-violation observed in the distribution of galaxies are due to new physics.

description: The dimension reduction of materials to a nanometer scale gives rise to several advantages in terms of
device applications, due to size and quantum confinement effects. Crystalline nanostructures such as nanowires have
received increasing attention due to potential applications in solar cells, nanoscale electronic, optical and sensing
devices, etc. This work reports the synthesis of nanostructured ZnO by the method of electrochemical deposition on
glass substrates covered with a thin film of SnO2 doped with F (SnO2:F). The influence of the deposition parameters
on the structural properties of the obtained ZnO films was studied by SEM and Raman spectroscopy. ZnO
nanostructured films were deposited by an electrochemical process using a three-electrode potentiostatic system with
saturated calomel electrodes as reference electrodes, from aqueous solution containing ZnCl2, KCl, pH = 4.00 and
flowing air or/and additional supplement of H2O2. The SEM micrographs demonstrate that the ZnO films consist of
nanowires. The Raman spectra of the obtained ZnO films with nanowires demonstrate the typical for ZnO vibration
bands. They most pronounced for the sample deposited with the highest H2O2 concentration. In order to increase the
conductivity experiments for doping of the obtained nanostructured ZnO films during the electrochemical deposition
are in progress.

description: Recurrent neural networks (RNNs) have drawn interest from machine learning researchers because of their effectiveness at preserving past inputs for time-varying data processing tasks. To understand the success and limitations of RNNs, it is critical that we advance our analysis of their fundamental memory properties. We focus on echo state networks (ESNs), which are RNNs with simple memoryless nodes and random connectivity. In most existing analyses, the short-term memory (STM) capacity results conclude that the ESN network size must scale linearly with the input size for unstructured inputs. The main contribution of this paper is to provide general results characterizing the STM capacity for linear ESNs with multidimensional input streams when the inputs have common low-dimensional structure: sparsity in a basis or significant statistical dependence between inputs. In both cases, we show that the number of nodes in the network must scale linearly with the information rate and poly-logarithmically with the ambient input dimension. The analysis relies on advanced applications of random matrix theory and results in explicit non-asymptotic bounds on the recovery error. Taken together, this analysis provides a significant step forward in our understanding of the STM properties in RNNs.

description: The purpose of the project is to develop a new PV solar roof which is capable of orienting itself
towards the sun in each moment of the day, without projecting over the perimeter of the building. This is achieved by
a balanced movement over its centre of gravity along with controlled motorized cable technologies. The approach of
the design is focused on adapting the structure and movement of industrial solar trackers to integrate them in
construction projects. Consequently, the scientific invention is the internationally registered patent presented by the
Universidad Politécnica de Madrid as part of its US Department of Energy Solar Decathlon 2009 Competition R&D
Programme. The results of this innovation will be integrated for the first time in the housing prototype, The B&W
House, competing in Washington in October of this year. However, the eventual commercial development is
considered a priority. The practical implementation of this PV roof system in the global market will set a milestone
for sustainable prefabricated residences, other buildings and uses.

We remark that there are infinitely many $p$-blocks $B$ with non-Abelian defect groups and $\ell(B) = p^r - 1$. We conjecture that the inequality $\ell(B) \leq p^r$ holds for an arbitrary $p$-block with defect group of sectional rank $r$. We show this to hold for a large class of $p$-blocks of various families of quasi-simple and nearly simple groups.

description: We report on the growth and characterization of copper indium disulfide (CIS) nanorods by electrodeposition
using anodized aluminum oxide (AAO) as the growth mask. The technique facilitates effective control of both the
stoichiometry and the diameters of the nanorods. The AAO nano-mask was prepared using a two-step anodization process.
The pore size in the anodized aluminum foil can be controlled by varying the anodization potential. Anhydrous salts of
CuCl2 and InCl3 were dissolved in an aqeous solution during the electrodeposition process. Using this technique we have
successfully grown CIS nanorods with diameters varying between 50 nm to 300 nm. The lengths of the nanorods were
between 5 μm to 20 μm. The stoichiometry of the nanorods can be effectively controlled by varying the electrodeposition
potential. The nanorods were separated from the substrates by ultrasound and were subsequently placed on a glass plate.
Metallic interdigitated structures were fabricated using standard photolithographic technique to facilitate electrical contacts
with the nanorods. Detailed characterizations of the structural and the optoelectronic properties of the nanorods were
performed by X-ray diffraction, transmission electron microscopy and I-V measurements on the materials.

description: We have shown, that photoactive, highly (001)-textured tungsten disulfide (WS2) films can be prepared
both on insulating as well as metallic substrates. The WS2 films are crystallized from X-ray-amorphous WS3+x films
by a rapid annealing process in an H2S atmosphere with the assistance of metal-sulfide droplets, which are formed,
when the eutectic temperature in the system metal-sulfur is exceeded. As promoters Ni, Co and Pd can be used,
where the eutectic temperatures with sulfur are in the range from 620 to 680 °C. From ex situ- and in situ-analysis a
modified model for the formation of the WS2 nanosheets was derived, which resembles the well-known VLS (vaporliquid-
solid)-model for the formation of nanorods (or whiskers), except that in our systems the precursor is also an
(amorphous) solid, and instead of 1-dimensional rods, 2-dimensional nanosheets are grown.
Especially, the preparation on metallic layers (W, TiN), which was not successful before, offers now the opportunity,
to prepare thin film solar cells from these WS2 films. First experiments to prepare thin film solar cells show, that
short circuits occur, most probably at grain boundaries, which have to be avoided or passivated.

description: We consider the Type 1 and Type 2 noncommutative Borsuk-Ulam conjectures of Baum, D$ą$browski, and Hajac: there are no equivariant morphisms $A \to A \circledast_δH$ or $H \to A \circledast_δH$, respectively, when $H$ is a nontrivial compact quantum group acting freely on a unital $C^*$-algebra $A$. Here $A \circledast_δH$ denotes the equivariant noncommutative join of $A$ and $H$; this join procedure is a modification of the topological join that allows a free action of $H$ on $A$ to produce a free action of $H$ on $A \circledast_δH$. For the classical case $H = \mathcal{C}(G)$, $G$ a compact group, we present a reduction of the Type 1 conjecture and counterexamples to the Type 2 conjecture. We also present some examples and conditions under which the Type 2 conjecture does hold.

description: Chromium(III) oxide is a classical collinear antiferromagnet with a linear magnetoelectric effect. We are presenting the measurements of the magnetoelectric susceptibility $α$ of a sputter-deposited 500-nm film and a bulk single-crystal of Cr$_\mathrm{2}$O$_\mathrm{3}$. We investigated the magnetic phase-transition and the critical exponent $β$ of the sublattice magnetization near Néel temperature. For the films, an exponent of 0.49(1) was found below 293 K, and changed to 1.06(4) near the Néel temperature of 298 K. For the single-crystal, the exponent was constant at 0.324(4). We investigated the reversal probability of antiferromagnetic domains during magnetoelectric field cooling. For the sputtered films, reversal probability was zero above 298 K and stabilized only below 293 K. We attribute this behavior to formation of grains during film growth, which gives different intergrain and intragrain exchange-coupling energies. For the single-crystal, reversal probability was stabilized immediately at the Néel temperature of 307.6 K.

description: Squeezed light, which is easily degraded by loss, could benefit from generation directly in optical fiber. Furthermore, highly nonlinear fiber could offer more efficient generation with lower pump power and shorter fiber lengths than standard single-mode fiber. We investigate non-polarization-maintaining highly nonlinear fiber (HNLF) for squeezed-light generation by characterizing possible sources of excess noise, including its zero-dispersion wavelength (ZDW) variation and polarization noise. We find significant ZDW variation and excess polarization noise. We believe the polarization noise is from non-linear polarization-mode dispersion. We model this polarization noise and find that it is likely to degrade Kerr squeezing but not squeezing from four-wave mixing.

description: This project consists of installing a 16.6 kW grid-connected solar-powered system that will be used to
offset the energy costs of electricity used by Lee County’s TK Davis Justice Center located in Opelika, AL, USA.
The project will monitor the performance of the system and make the on-going results available to officials and the
public. Information gathered through the system’s design, installation, and performance monitoring will provide
valuable research information concerning practical photovoltaic alternative energy systems design and integration.
Its research value will be enhanced by its additional asset as an excellent teaching and demonstration tool. The
purpose of this program is to aid in photovoltaic system design by providing accurate and in-depth information on
likely system power output and load consumption, necessary backup power during the operation of the system, and
the financial impacts of installing the proposed system. The system is vitally important to the overall scope of the
alternative energy plan envisioned by the Lee County Commission and Auburn University’s SRI. This project hopes
to establish a message that local governments need to take an active role in increasing energy-efficiency and being
environmentally friendly while reducing operational costs for its citizens over the long-term.

description: 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 381-384
description: Luminescent solar concentrators suffer from a high loss of emitted photons through the surfaces.
Previous measurements on filled waveguides showed 40-50% of all the absorbed energy and 50-60% of all absorbed
photons were lost through the top and bottom of the waveguide. Aligning the dye molecules in a preferred direction
can be beneficial to the light output, since fluorescent dyes tend to be dichroic in absorption and emission. Planar
alignment of the dye molecules leads to an increase in surface losses, while the total edge output of these planar
arrays is similar to the total output of an isotropic dye array. Homeotropic aligned waveguides show a decrease in
surface-loss compared to an isotropic waveguide. Emitted photons are directed more towards the edges in this
alignment and so surface losses are greatly reduced. However, edge output does not increase, likely a result of
increased re-absorption of an emitted photon by other dye molecules. These internal losses are related to the small
Stokes-shift of the dye molecules, non-unity quantum efficiency and trapping of photons in the thin dye layer.
Statistical steady state in turbulent droplet condensation

description: Motivated by systems in which droplets grow and shrink in a turbulence-driven supersaturation field, we investigate the problem of turbulent condensation in a general manner. Using direct numerical simulations we show that the turbulent fluctuations of the supersaturation field offer different conditions for the growth of droplets which evolve in time due to turbulent transport and mixing. Based on that, we propose a Lagrangian stochastic model for condensation and evaporation of small droplets in turbulent flows. It consists of a set of stochastic integro-differential equations for the joint evolution of the squared radius and the supersaturation along the droplet trajectories. The model has two parameters fixed by the total amount of water and the thermodynamic properties, as well as the Lagrangian integral timescale of the turbulent supersaturation. The model reproduces very well the droplet size distributions obtained from direct numerical simulations and their time evolution. A noticeable result is that, after a stage where the squared radius simply diffuses, the system converges exponentially fast to a statistical steady state independent of the initial conditions. The main mechanism involved in this convergence is a loss of memory induced by a significant number of droplets undergoing a complete evaporation before growing again. The statistical steady state is characterised by an exponential tail in the droplet mass distribution. These results reconcile those of earlier numerical studies, once these various regimes are considered.
