description: Inconsistent conclusions are obtained from recent active galactic nuclei (AGNs) accretion disk inter-band time-lag measurements. While some works show that the measured time lags are significantly larger (by a factor of $\sim 3$) than the theoretical predictions of the Shakura \& Sunyaev disk (SSD) model, others find that the time-lag measurements are consistent with (or only slightly larger than) that of the SSD model. These conflicting observational results might be symptoms of our poor understanding of AGN accretion physics. Here we show that sources with larger-than-expected time lags tend to be less-luminous AGNs. Such a dependence is unexpected if the inter-band time lags are attributed to the light-travel-time delay of the illuminating variable X-ray photons to the static SSD. If, instead, the measured inter-band lags are related not only to the static SSD but also to the outer broad emission-line regions (BLRs; e.g., the blended broad emission lines and/or diffuse continua), our result indicates that the contribution of the non-disk BLR to the observed UV/optical continuum decreases with increasing luminosity ($L$), i.e., an anti-correlation resembling the well-known Baldwin effect. Alternatively, we argue that the observed dependence might be a result of coherent disk thermal fluctuations as the relevant thermal timescale, $τ_{\mathrm{TH}}\propto L^{0.5}$. With future accurate measurements of inter-band time lags, the above two scenarios can be distinguished by inspecting the dependence of inter-band time lags upon either the BLR components in the variable spectra or the timescales.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 3975-3978
description: This paper presents a study of two PV plants (>5MWp) in Greece, which have a significant difference ~8%
in PR. The two PV plants have been installed with the same PV module technology and central inverters with an
optimum and similar design. During their operation, the plants did not present any severe malfunctions and had an
availability of >98%. Both plants are operating under comparable conditions in Greece, in terms of ambient temperature
in Central and South Greece and are within the 2nd year of operation. In this respect, it will be presented where this
discrepancy in PR comes from, based on real data. The aim is to provide a clear understanding how contractual aspects of
an EPC/O&M contract (the way PR values are calculated) and also technical aspects (PV modules, inverters) influence
the PR values themselves. These two aspects are capable of significantly influencing the final performance ratio values of
the PV plants.

description: In \cite{BKN} the authors initiated a study of the representation theory of classical Lie superalgebras via a cohomological approach. Detecting subalgebras were constructed and a theory of support varieties was developed. The dimension of a detecting subalgebra coincides with the defect of the Lie superalgebra and the dimension of the support variety for a simple supermodule was conjectured to equal the atypicality of the supermodule. In this paper the authors compute the support varieties for Kac supermodules for Type I Lie superalgebras and the simple supermodules for $\mathfrak{gl}(m|n)$. The latter result verifies our earlier conjecture for $\mathfrak{gl}(m|n)$. In our investigation we also delineate several of the major differences between Type I versus Type II classical Lie superalgebras. Finally, the connection between atypicality, defect and superdimension is made more precise by using the theory of support varieties and representations of Clifford superalgebras.

description: Catalano and Fiore propose a scheme to transform a linearly-homomorphic encryption into a homomorphic encryption scheme capable of evaluating quadratic computations on ciphertexts. Their scheme is based on the linearly-homomorphic encryption (such as Goldwasser-Micali, Paillier and ElGamal) and need to perform large integer operation on servers. Then, their scheme have numerous computations on the servers. At the same time, their scheme cannot verify the computations and cannot evaluate more than degree-4 computations. To solve these problems, we no longer use linearly-homomorphic encryption which based on number theory assumptions. We use label and pseudorandom function to encrypt message, which significantly reduce the computations on the servers and enable us to use homomorphic MACs technology to realize verifiable computations naturally. We also extend the method to construct $d$-server schemes, which allow the client to delegate degree-$d$ computations on outsourced data.

description: The efficiency of industrial bifacial n-type cells is mostly limited by the loss in VOC after firing of
screen printed metal pastes. We have investigated the mechanism responsible for this loss by varying the metal
fraction on either side of the cell and determined the actual influence of surface geometry, diffusion layers and pastes.
The experimental results indicate a more detrimental influence of metal pastes on the boron emitter side. This can be
attributed to more aggressive pastes and less shielded contacts as in the case of phosphorous diffused emitters.

archaeological excavation

description: This report details the second archaeological excavation that took place at 195 Prince
George Street, known as the John Brice II House or the Judge John Brice House. This two-story
brick dwelling built by John Brice II is considered by some as a forerunner to the elaborate
colonial homes built in Annapolis during the mid- to late-18th century. John Brice II was a public
servant and also ran a small store in Annapolis. His family owned and lived in the property until the
mid-19th century. The Halligan-Adair family purchased the home in 1917 and continues to occupy
the property today.
The first season of archaeological excavations was in the fall of 1989, and is detailed in a
report written by Julie Ernstein (1990). The second season of excavations took place as part of
the University of Maryland Summer 2013 Field School in Urban Archaeology. As part of this
season of excavation, 10 shovel test pits were dug at approximately 20 foot intervals across the
front and back yards of the property. Four 5’ x 5’ excavation units were placed in the backyard
of the property. Only one of these units was excavated to sterile soil. The remaining three were
covered with plastic landscaping tarp before being backfilled so that excavation of these units
could continue in the future.
The preliminary excavations of the John Brice II House show three large scale yard
modifications to the backyard landscape, each roughly corresponding with the change in
property owners. The oldest levels recovered from the backyard contained a late 18th oyster shell
path and associated garden bed that are likely evidence of the landscaping features of the Brice
Family occupation of the property. The 19th century archaeological occupation levels indicate a
reorientation of the backyard landscape, and several large features dating to this time period were
discovered in the last week of excavation. Further research is required to determine the exact
nature and relationships of these features.
Continued excavations have the potential to reveal more information about the changes in
the urban landscape of Annapolis from the 18th century to the 21st century as well as information
about the lives of the families who occupied this property.

description: A simple model to describe the energetic phase diagram of electron-doped cuprate superconductor is developed. Interband pairing operates between the UHB and the defect states created by doping and supplied by both extincting HB-s. Two defect subbands correspond to the ($π, 0$) and ($π/2,π/2$) momentum regions. Extended doping quenches the bare normal state gaps (pseudogaps). Maximal transition temperature corresponds to overlapping bands ensemble intersected by the chemical potential. Illustrative results for $T_c$, pseudo- and superconducting gaps are calculated on the whole doping scale. Major characteristics features on the phase diagram are reproduced. Anticipated manifestation of gaps doping dynamics is discussed.

description: Outsourcing computation has gained significant popularity in recent years due to the prevalence of cloud computing. There are two main security concerns in outsourcing computation: how to guarantee the cloud server performs the computation correctly and how to keep the client's data secret. The {\em single-server verifiable computation} (SSVC) of Gennaro, Gentry and Parno (Crypto'10) enables a client to delegate the computation of a function $f$ on any input $x$ with both concerns highly relieved, but only results in {\em computationally secure} schemes that {\em lack practical efficiency}. While the SSVC schemes use a single server, in this paper we develop a {\em multi-server verifiable computation} (MSVC) model where the client shares both $f$ and $x$ among multiple servers, each server performs a set of computations on its shares, and finally the client reconstructs $f(x)$ from all servers' results. In this MSVC model we propose a generic construction for outsourcing computations of the form $F{\bf x}$, where $F$ is a matrix and $\bf x$ is a vector. Our generic construction achieves {\em information-theoretic security, input privacy} and {\em function privacy}. By optimizing the parameters, we obtain both a 3-server scheme,which uses the least number of servers, and a 4-server scheme, which incurs the least workload. By decomposing many polynomial computations as a two-stage computation, where the first-stage has the form $F{\bf x}$ and the second-stage is fast, and delegating the first-stage computation, we obtain MSVC schemes for these polynomials. We implement our MSVC schemes and show that they are among the most {\em practical} ones to date.

description: The increasingly common requirement for higher education courses to include reflective writing as part of assessment practices places additional demands on novice writers. Complex and self-referential assessment criteria mean that students on foundation and pre-sessional courses in particular find it hard to decode and match descriptors, and to balance subjectivity and critical analysis. English for Academic Purposes (EAP), the most widely adopted approach to teaching academic writing in higher education, prioritises objectivity, and teaches students to recognise generic patterns of text organisation – though it seldom includes reflective writing itself as a genre. In contrast, the less familiar teaching approach of academic literacies explores students’ subjectivity, more obviously relevant to reflection, often through the development of an authentic narrative voice. As in other forms of academic writing, voice in reflective writing can be seen as a construct. It conveys a persona via the narrative, and an ethos via its specialised content. However, unlike other forms of academic writing, the persona in reflective writing must simultaneously communicate the author’s private and public self.

description: Gravitational theories do not admit gauge invariant local operators. We study the limits under which there exists a quasi-local description for a class of non-local gravitational observables where a sum over worldlines plays the role of the Wilson line for gauge theory observables. We study non-local corrections to the local description and circumstances where these corrections become large. We find that these operators are quasi-local in flat space and AdS, but fail to be quasi-local in de Sitter space.

description: Photonic brain-inspired platforms are emerging as novel analog computing devices, enabling fast and energy-efficient operations for machine learning. These artificial neural networks generally require tailored optical elements, such as integrated photonic circuits, engineered diffractive layers, nanophotonic materials, or time-delay schemes, which are challenging to train or stabilize. Here we present a neuromorphic photonic scheme - photonic extreme learning machines - that can be implemented simply by using an optical encoder and coherent wave propagation in free space. We realize the concept through spatial light modulation of a laser beam, with the far field that acts as feature mapping space. We experimentally demonstrated learning from data on various classification and regression tasks, achieving accuracies comparable to digital extreme learning machines. Our findings point out an optical machine learning device that is easy-to-train, energetically efficient, scalable and fabrication-constraint free. The scheme can be generalized to a plethora of photonic systems, opening the route to real-time neuromorphic processing of optical data.

description: The aim of this paper is to give an indication of the optimum amount of photovoltaic power in a given
electrical system, when peak-shaving is the goal. Linear regression is applied with photovoltaic generation data and
consumption data as input. The output is the optimal amount of photovoltaic power, which can be installed under the
given circumstances. Two different types of photovoltaic installations are investigated; roof-top systems pointing in
“all directions” and utility scale systems pointing south. The results are that the required amount of photovoltaic
power can be reduced with app. 12% when installing only south pointing systems. This also optimizes the return of
investment. Besides, the up to 10% of the Danish yearly consumption can easily be supplied by photovoltaic.

We study the average density matrix arising from the ensemble induced, in contrast to previous studies where the average values of purity, concurrence, and entropy were considered; we further discuss when one or the other approach is relevant. The two approaches agree in the limit of large environments. Analytic results for the average density matrix and its purity are presented in linear response approximation. The two-qubit system is analysed, mainly numerically, in more detail.

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1482-1485
description: A symmetric structure has been generally used to fabricate heterojunction with intrinsic thin layer
(HIT) solar cells, i.e. hydrogenated amorphous silicon (a-Si:H) forms the emitter (i-p stack) and the back surface field
(BSF) (i-n stack), and transparent conductive oxide (TCO) covered with metallic electrodes is used on either side. In
this contribution, we present the influence of the intrinsic a-Si:H layer thickness in both the emitter and BSF on the
passivation and solar-cell performance. Using a thicker intrinsic a-Si:H layer in the emitter results in a longer
effective minority carrier lifetime, indicating a better passivation of the a-Si:H/c-Si interface and leading to a higher
open-circuit voltage (Voc). In the BSF, thinner or even no intrinsic a-Si:H can be used to increase FF. In both the
emitter and BSF, the fill factor (FF) is strongly related to the intrinsic a-Si:H layer thickness. In our investigation, the
short circuit current density (Jsc) does not change obviously with the variation of the intrinsic a-Si:H layer thickness.
In the case that a full metal contact is used on the BSF side, the solar cell without back TCO shows a better
performance. An efficiency of 17.5% is obtained in the flat HIT solar cell without intrinsic a-Si:H passivating layer
and TCO on the side of BSF.

description: As an example of thin composite layers we consider single and double grids of periodically arranged interacting wires loaded with a certain distributed reactive impedance. Currents induced to the wires by a normally incident plane wave are rigorously calculated and the corresponding dipole moment densities are determined. Using this data and the averaged fields we assign mesoscopic material parameters for the proposed grid structures. These parameters depend on the number of grids, and measure the averaged induced polarizations. It is demonstrated that properly loaded double grids possess polarization response that over some frequency range can be described by assigning negative values for the mesoscopic parameters. Discussion is conducted on the physical meaningfulness to assign such material parameters for thin composite slabs. The results predicted by the proposed method for the double-grid structures are compared with the results obtained using the commonly adopted S-parameter retrieval procedure.

description: Nematic liquid crystal elastomers (LCE) exhibit unique mechanical properties, placing them in a category distinct from other viscoelastic systems. One of their most celebrated properties is the 'soft elasticity', leading to a wide plateau of low, nearly-constant stress upon stretching, a characteristically slow stress relaxation, enhanced surface adhesion, and other remarkable effects. The dynamic soft response of LCE to shear deformations leads to the extremely large loss behaviour with the loss factor tanδ approaching unity over a wide temperature and frequency ranges, with clear implications for damping applications. Here we investigate this effect of anomalous damping, optimising the impact and vibration geometries to reach the greatest benefits in vibration isolation and impact damping by accessing internal shear deformation modes. We compare impact energy dissipation in shaped samples and projectiles, with elastic wave transmission and resonance, finding a good correlation between the results of such diverse tests. By comparing with ordinary elastomers used for industrial damping, we demonstrate that the nematic LCE is an exceptional damping material and propose directions that should be explored for further improvements in practical damping applications.

description: We present a small perturbation quasi-steady-state microwave detected photoconductance decay
method that is significantly improved using novel quality of decay control technique. As a result, measurements of
excess carrier decay lifetime, eff.d and of the steady-state effective lifetime, eff.d are unified in one parameter-free
self-consistent approach. The approach shows excellent quantitative correlation with Sinton QSSPC. Advantages of
the method relate to wafer mapping. The emitter saturation current, J0, maps reveal the common presence of high J0
passivation defects that can degrade cell performance. In an automated corona-charging-measuring sequence, the
approach enables quantitative assessment of the state of field-effect passivation using a novel parameter; charge to
saturation, Qts. It is believed that passivation defect mapping and field-effect assessment can benefit passivation
engineering for high efficiency cells.

description: 14-3-3 proteins are abundant, intramolecular proteins that play a pivotal role in cellular signal transduction by interacting with phosphorylated ligands. In addition, they are molecular chaperones that prevent protein unfolding and aggregation under cellular stress conditions in a similar manner to the unrelated small heat-shock proteins. In vivo, amyloid β (Aβ) and α-synuclein (α-syn) form amyloid fibrils in Alzheimer's and Parkinson's diseases, respectively, a process that is intimately linked to the diseases' progression. The 14-3-3ζ isoform potently inhibited in vitro fibril formation of the 40-amino acid form of Aβ (Aβ40) but had little effect on α-syn aggregation. Solution-phase NMR spectroscopy of 15N-labeled Aβ40 and A53T α-syn determined that unlabeled 14-3-3ζ interacted preferentially with hydrophobic regions of Aβ40 (L11-H21 and G29-V40) and α-syn (V3-K10 and V40-K60). In both proteins, these regions adopt β-strands within the core of the amyloid fibrils prepared in vitro as well as those isolated from the inclusions of diseased individuals. The interaction with 14-3-3ζ is transient and occurs at the early stages of the fibrillar aggregation pathway to maintain the native, monomeric, and unfolded structure of Aβ40 and α-syn. The N-terminal regions of α-syn interacting with 14-3-3ζ correspond with those that interact with other molecular chaperones as monitored by in-cell NMR spectroscopy.

A few cooking emotionally supportive networks have been concentrated to give clients directions dependent on the plans well ordered, utilizing multi-media substance. These frameworks, as a rule, aggravate client's cooking procedure constraining them to give data to the framework so as to give them advantageous data. In this sense, these frameworks are viewed as "client-driven". We offer a framework called "Smart Kitchen" viewed as in "client-driven", in which a client can cook regularly deprived of being worried concerning the framework. Smart Kitchen can comprehend cooking forms, at the end of the day, what the client is doing. We will examine the structure of the Smart Kitchen framework and clarify three fundamental units of the following sustenance, perceiving nourishment material, and perceiving cooking activity.

description: We estimate the I=0 scalar meson sigma/f_0(600) parameters from pi-pi and gamma-gamma scattering data below 700 MeV using an improved analytic K-matrix model. A fit of the hadronic data gives a complex pole mass M_sigma= 422-i290 MeV, while simultaneous best fits of the gamma-gamma to pi+pi-, pi0pi0 data give a direct width of (0.13+-0.05)keV, a rescattering component of (2.7+-0.4)keV and a total (direct+rescattering) width of (3.9+-0.6)keV. "Running" these results to the physical real axis, the small "direct" gamma-gamma and the large hadronic widths at the "on-shell" mass are compatible with QCD spectral sum rules (QSSR) and some low-energy theorems (LET) expectations for an unmixed lowest mass glueball/gluonium sigma_B of a mass around 1 GeV and a large OZI-violation decay into pi-pi.

130 μm-thick and the 290 μm-thick cells are FZ material, whereas the 45 μm-thick cells are monocrystalline epitaxial
layers fabricated by the porous silicon process. All cells are processed in one batch. The efficiency of the champion
cells are 22.5 % for 290 μm, 22.6 % for 130 μm, 21.1 % for 90 μm and 18.9 % for 45 μm cell thickness. We
investigate the loss mechanisms of all cells. Electron transport in the base causes the highest losses in all cells. The
power loss decreases with decreasing cell thickness from 2.5 - 0.9 % absolute efficiency loss at 290 - 45 μm-thick
cells.

description: BACKGROUND: Auriculocondylar syndrome (ARCND) is a rare genetic disease that affects structures derived from the first and second pharyngeal arches, mainly resulting in micrognathia and auricular malformations. To date, pathogenic variants have been identified in three genes involved in the EDN1-DLX5/6 pathway (PLCB4, GNAI3 and EDN1) and some cases remain unsolved. Here we studied a large unsolved four-generation family. METHODS: We performed linkage analysis, resequencing and Capture-C to investigate the causative variant of this family. To test the pathogenicity of the CNV found, we modelled the disease in patient craniofacial progenitor cells, including induced pluripotent cell (iPSC)-derived neural crest and mesenchymal cells. RESULTS: This study highlights a fourth locus causative of ARCND, represented by a tandem duplication of 430 kb in a candidate region on chromosome 7 defined by linkage analysis. This duplication segregates with the disease in the family (LOD score=2.88) and includes HDAC9, which is located over 200 kb telomeric to the top candidate gene TWIST1. Notably, Capture-C analysis revealed multiple cis interactions between the TWIST1 promoter and possible regulatory elements within the duplicated region. Modelling of the disease revealed an increased expression of HDAC9 and its neighbouring gene, TWIST1, in neural crest cells. We also identified decreased migration of iPSC-derived neural crest cells together with dysregulation of osteogenic differentiation in iPSC-affected mesenchymal stem cells. CONCLUSION: Our findings support the hypothesis that the 430 kb duplication is causative of the ARCND phenotype in this family and that deregulation of TWIST1 expression during craniofacial development can contribute to the phenotype.

description: Recent developments in two-dimensional (2D) magnetism have motivated the search for novel van-der Waals (vdWs) magnetic materials to explore new magnetic phenomenon in the 2D limit. Metal thiophosphates, MPX3, is a class of magnetic vdWs materials with antiferromagnetic (AFM) ordering persisting down to the atomically thin limit. The magnetism in this material family has been found to be highly dependent on the choice of transition metal M. In this work, we have synthesized the intermediate compounds Ni1-xMnxPS3 (0 < x < 1) and investigated their magnetic properties. Our study reveals that the variation of Ni and Mn content in Ni1-xMnxPS3 can efficiently tune the spin-flop transition, likely due to the modulation of the magnetic anisotropy. Such effective tunning offers a promising candidate to engineer 2D magnetism for future device applications.
Discrete rearranging disordered patterns, part I: Robust statistical tools in two or three dimensions

description: Discrete rearranging patterns include cellular patterns, for instance liquid foams, biological tissues, grains in polycrystals; assemblies of particles such as beads, granular materials, colloids, molecules, atoms; and interconnected networks. Such a pattern can be described as a list of links between neighbouring sites. Performing statistics on the links between neighbouring sites yields average quantities (hereafter "tools") as the result of direct measurements on images. These descriptive tools are flexible and suitable for various problems where quantitative measurements are required, whether in two or in three dimensions. Here, we present a coherent set of robust tools, in three steps. First, we revisit the definitions of three existing tools based on the texture matrix. Second, thanks to their more general definition, we embed these three tools in a self-consistent formalism, which includes three additional ones. Third, we show that the six tools together provide a direct correspondence between a small scale, where they quantify the discrete pattern's local distortion and rearrangements, and a large scale, where they help describe a material as a continuous medium. This enables to formulate elastic, plastic, fluid behaviours in a common, self-consistent modelling using continuous mechanics. Experiments, simulations and models can be expressed in the same language and directly compared. As an example, a companion paper (Marmottant, Raufaste and Graner, joint paper) provides an application to foam plasticity.

description: The value of the performance ratio (PR) depends on the sensor of the irradiance measurement which is
well known [1-2]. The amount of energy measured over the year varies for different irradiance sensor technologies
[3] and leads to module-sensor mismatches between the technologies [4]. Depending on which technology is used as
irradiance sensor, the performance ratio and also its interpretation changes. Using the same technology for the
irradiance sensor and the PV modules, the performance ratio directly provides information about the status and
possible performance issues of the PV modules beyond inherent effects such as seasonal variations of the PV module.
With a pyranometer, practically the entire incoming radiation of the sun is measured. Thus the performance ratio
based on a pyranometer indicates the efficiency of the PV module. The pyranometer also exhibits good performance
stability which is why it is suitable as a sensor for investigations of the performance stability of PV modules.
Especially in the comparison between performance ratio values based on different technologies, a critical evaluation
is important. In the presented work, several technologies measuring the irradiance are compared and the differences
are pointed out. The comparison is based on data of one year obtained in the rural region of Chiemgau in southern
Germany. The differences between the technologies are evaluated and given in a matrix for direct comparison.
Differences up to 3.4 percent in PR for yearly evaluations were observed.

description: To evaluate the role of Total Solar Irradiance (TSI) on Northern Hemisphere (NH) surface air temperature trends it is important to have reliable estimates of both quantities. 16 different TSI estimates were compiled from the literature. 1/2 of these estimates are low variability and 1/2 are high variability. 5 largely-independent methods for estimating NH temperature trends were evaluated using: 1) only rural weather stations; 2) all available stations whether urban or rural (the standard approach); 3) only sea surface temperatures; 4) tree-ring temperature proxies; 5) glacier length temperature proxies. The standard estimates using urban as well as rural stations were anomalous as they implied a much greater warming in recent decades than the other estimates. This suggests urbanization bias might still be a problem in current global temperature datasets despite the conclusions of some earlier studies. Still, all 5 estimates confirm it is currently warmer than the late 19th century, i.e., there has been some global warming since 1850. For the 5 estimates of NH temperatures, the contribution from direct solar forcing for all 16 estimates of TSI was evaluated using simple linear least-squares fitting. The role of human activity in recent warming was then calculated by fitting the residuals to the UN IPCC's recommended anthropogenic forcings time series. For all 5 NH temperature series, different TSI estimates implied everything from recent global warming being mostly human-caused to it being mostly natural. It seems previous studies (including the most recent IPCC reports) that had prematurely concluded the former failed to adequately consider all the relevant estimates of TSI and/or to satisfactorily address the uncertainties still associated with NH temperature trend estimates. Several recommendations are provided on how future research could more satisfactorily resolve these issues.

description: Silicon nanocrystals (Si NCs) embedded in Si-based dielectrics provide a Si-based high band gap
material (1.7 eV) and enable the construction of all-crystalline Si tandem solar cells. However, Si nanocrystal
formation involves high-temperature annealing which deteriorates the properties of any previously established
selective contacts. The inter-diffusion of dopants during high-temperature annealing alters Si NC formation and limits
the built-in voltage. Furthermore, most devices presented so far also involve electrically active bulk Si and therefore
do not allow a clear separation of the observed photovoltaic effect of the quantum dot layer from that of the bulk Si
substrate. A membrane route is presented for quantum dot based p-i-n solar cells to overcome these limitations. In
this approach, the formation of both selective contacts is carried out after high-temperature annealing and therefore
not affected by the latter. P-i-n solar cells are investigated with Si NCs embedded in silicon carbide in the intrinsic
region. Open-circuit voltages of up to 370 mV are shown for the NC layer. An optical model of the device is
presented for improving the cell current. Finally device failure due to damaged insulation layers is analysed by
electron beam induced current measurements.
Comment on Experiments Related to the Aharonov-Bohm Phase Shift

description: Recent experiments undertaken by Caprez, Barwick, and Batelaan should clarify the connections between classical and quantum theories in connection with the Aharonov-Bohm phase shift. It is pointed out that resistive aspects for the solenoid current carriers play a role in the classical but not the quantum analysis for the phase shift. The observed absence of a classical lag effect for a macroscopic solenoid does not yet rule out the possibility of a lag explanation of the observed phase shift for a microscopic solenoid.
