description: We designed and simulated freestanding dielectric optical metasurfaces based on arrays of etched nanoholes in a silicon membrane. We showed $2π$ phase control and high forward transmission at mid-infrared wavelengths by tuning the dimensions of the holes. We also identified the mechanisms responsible for high forward scattering efficiency and showed that these conditions are connected with the well-known Kerker conditions already proposed for isolated scatterers. A beam deflector was designed and optimized through sequential particle swarm and gradient descent optimization to maximize transmission efficiency and reduce unwanted grating orders. Such freestanding silicon nanohole array metasurfaces are promising for the realization of silicon based mid-infrared optical elements.

description: Two dimensional tensor networks such as projected entangled pairs states (PEPS) are generally hard to contract. This is arguably the main reason why variational tensor network methods in 2D are still not as successful as in 1D. However, this is not necessarily the case if the tensor network represents a gapped ground state of a local Hamiltonian; such states are subject to many constraints and contain much more structure. In this paper we introduce a new approach for approximating the expectation value of a local observable in ground states of local Hamiltonians that are represented as PEPS tensor-networks. Instead of contracting the full tensor-network, we try to estimate the expectation value using only a local patch of the tensor-network around the observable. Surprisingly, we demonstrate that this is often easier to do when the system is frustrated. In such case, the spanning vectors of the local patch are subject to non-trivial constraints that can be utilized via a semi-definite program to calculate rigorous lower- and upper-bounds on the expectation value. We test our approach in 1D systems, where we show how the expectation value can be calculated up to at least 3 or 4 digits of precision, even when the patch radius is smaller than the correlation length.

description: Melirrhophetes foersteri Rothschild and Hartert Melirrhophetes foersteri Rothschild and Hartert, 1911b: 12 (Rawlinson Mountains, north of Huon Gulf, German New Guinea). Now Melidectes foersteri (Rothschild and Hartert, 1911). See Gilliard, 1959, Salomonsen, 1967: 418, Diamond, 1972: 387–389, Coates, 1990: 263, and Higgins et al., 2008: 614. LECTOTYPE: AMNH 693847, [adult male], collected in the Rawlinson Mountains, 06.30S, 147.15E (PNG, 1984), Huon Peninsula, Morobe Province, Papua New Guinea, in November 1910, by Christian Keysser. From the Rothschild Collection. COMMENTS: In the original description, Rothschild and Hartert described the adult male and female and said that the types, in the Rothschild Collection, had been obtained from Professor Foerster. The male and the female specimens were therefore syntypes; a third unsexed specimen has no taxonomic standing. Hartert (1919a: 175) listed the presumed male as the type, thereby designating it the lectotype of M. foersteri; the presumed female becomes the paralectotype: AMNH 693848. All three of these specimens were collected by Keysser, but if any had an original label, it is no longer present. The Rothschild labels are dated ‘‘ xi 1910.’’ Hartert (1919a: 175) mistakenly gave the collecting year as ‘‘1911.’’

description: Experiments on quantum degenerate Fermi gases of magnetic atoms and dipolar molecules begin to probe their broken symmetry phases dominated by the long-range, anisotropic dipole-dipole interaction. Several candidate phases including the p-wave superfluid, the stripe density wave, and a supersolid have been proposed theoretically for two-dimensional spinless dipolar Fermi gases. Yet the phase boundaries predicted by different approximations vary greatly, and a definitive phase diagram is still lacking. Here we present a theory that treats all competing many-body instabilities in the particle-particle and particle-hole channel on equal footing. We obtain the low temperature phase diagram by numerically solving the functional renormalization-group flow equations and find a nontrivial density wave phase at small dipolar tilting angles and strong interactions, but no evidence of the supersolid phase. We also estimate the critical temperatures of the ordered phases.

description: Roth&Rau AG is introducing the next generation of in-line equipment for crystalline silicon solar cell
production. It is based on the well-known SiNA® system [1], which has been sold more than 270 times. In contrast to
the current system the new system is being characterized by its extremely high grade of modularization. There are
three base modules: a lock module for loading and unloading wafers and the separation between different deposition
or etching processes, a buffer module for pre-heating or cooling down the wafers, and a process module for plasma
etching or deposition processes. The modules are available in two sizes: the SiNA® L with a carrier load of 25 wafers
(156 × 156 mm2) and the SiNA® XL with a carrier load of 50 wafers. With those two sizes the throughput of the
SiNA® is scalable and one system is therefore capable for solar cell production lines with an annual capacity from 30
up to 100 MWp.

description: Im Rahmen dieser Dissertation wurden Experimente zur Wechselwirkung von schnellen Atomen mit Oberflächen von Oxidkristallen, Metallkristallen und ultradünnen Oxidfilmen auf Metalloberflächen durchgeführt und modellhaft beschreiben. Die Experimente wurden im Regime der streifenden Streuung für Energien im keV-Bereich durchgeführt. Diese Streugeometrie bietet den Vorteil einer außerordentlich hohen Oberflächensensitivität und somit die Möglichkeit, die kristallographischen Eigenschaften der obersten Atomlage zu untersuchen. Darüber hinaus wurden Experimente zur Bestimmung des Energieverlustes der an den verschiedenen Oberflächen gestreuten Projektile und zur, durch diese Projektile induzierten, Elektronenemission durchgeführt. Die Anregungsenergie für die Elektronenemission und Exzitonen wurde an der Alumina/NiAl(110)- und der SiO2/Mo(112)- Oberfläche für die Streuung von He bestimmt. Durch die Bestimmung der Anzahl von emittierten Elektronen in Abhängigkeit des azimutalen Winkels konnten die Strukturen von obersten Lagen von Adsorbaten mit der Methode der Ionenstrahltriangulation bestimmt werden.
description: In the framework of the present dissertation the interactions of fast atoms with surfaces of bulk oxides, metals and thin films on metals were studied. The experiments were performed in the regime of grazing incidence of atoms with energies of some keV. The advantage of this scattering geometry is the high surface sensibility and thus the possibility to determine the crystallographic and electronic characteristics of the topmost surface layer. In addition to these experiments, the energy loss and the electron emission induced by scattered projectiles was investigated. The energy for electron emission and exciton excitation on Alumina/NiAl(110) and SiO2/Mo(112) are determined. By detection of the number of projectile induced emitted electrons as function of azimuthal angle for the rotation of the target surface, the geometrical structure of atoms forming the topmost layer of different adsorbate films on metal surfaces where determined via ion beam triangulation.

technologies has been compared. This paper describes quantitative analysis results of output loss for PV modules to
clarify the behavior of seven PV technologies in the field. As a result, annual performance ratios varied from 97% to
82% among the different modules. Spectral dependence of the amorphous single and tandem modules and irradiance
dependence of CIS modules are confirmed. It is shown that quantitative analysis method is useful how the

description: Ao longo dos anos a dor musculoesquelética foi tratada pela ortopedia com atenção voltada para estruturas específicas como articulações ou discos intervertebrais. Entretanto uma mudança tem ocorrido nas últimas décadas, e há um crescente interesse nos componentes neuroafetivos da dor musculoesquelética crônica, tais como redução da inibição descendente, sensibilização central e periférica e alterações das vias corticais definidas como Matriz de dor. Essa revisão narrativa identifica e descreve os efeitos da Educação em Neurociência da dor (END) aplicada por fisioterapeutas sobre as dores musculoesqueléticas crônicas. Pesquisou-se as bases de dados PubMed, Psycinfo e PEDro, o que gerou 83 artigos para aplicação dos critérios de elegibilidade. Após essa etapa, os dados foram extraídos de 6 estudos que identificaram que a END junto à Fisioterapia exerce como efeitos, melhorias sobre a sensibilidade à dor, cinesiofobia e funcionalidade, refletindo na saúde emocional e qualidade de vida dos indivíduos. Essa revisão destaca a escassez de evidências nessa área específica, na qual a combinação em questão mostra-se relevante no tratamento da dor musculoesquelética crônica. Dessa forma sugere-se a necessidade de futuras pesquisas.

description: Two main results will be presented in our paper. First, we will prove the regularity of solutions to axially symmetric Navier-Stokes equations under a $log$ supercritical assumption on the horizontally radial component $u^r$ and vertical component $u^z$, accompanied by a $log$ subcritical assumption on the horizontally angular component $u^θ$ of the velocity. Second, the precise Green function for the operator $-(Δ-\frac{1}{r^2})$ under the axially symmetric situation, where $r$ is the distance to the symmetric axis, and some weighted $L^p$ estimates of it will be given. This will serve as a tool for the study of axially symmetric Navier-Stokes equations. As an application, we will prove the regularity of solutions to axially symmetric Navier-Stokes equations under a critical (or a subcritical) assumption on the angular component $w^θ$ of the vorticity.

description: The measuring technique depicted in this work provides a quantitative carrier lifetime and doping
concentration mapping with a spatial resolution of down to 1 μm. While the typical resolution limit of established
mapping and imaging methods is limited due to large diffusion lengths above 5 μm, our setup significantly enhances this
limit by measuring under high injection levels. This allows for detailed quantitative analyses on the recombination
activity of defects such as grain boundaries and dislocations, and on the doping concentration of microscopic
technological structures. The presented technique is based on confocal micro photoluminescence spectroscopy. The
confocal microscope setup permits for focussed laser illumination and fast low-noise detection of the emitted
luminescent radiation. The carrier lifetime and doping concentration is determined by a calibration of the depth
dependent luminescent radiation with results from two-dimensional simulations generated by the continuity equations.

description: The COVID-19 pandemic and rising minimum wage prompted access services managers to delve deeper into data we were already collecting in order to better understand when and how the main library at the University of Maryland is used. This exploratory project involved gathering, reconciling, and identifying trends in hourly usage data from different systems, with the goal of maximizing what the library can offer with its current resources and to advocate for more funding, if needed. We will share our experience undertaking this work, discuss how we have and will apply this data, and offer suggestions for others interested in doing something similar at their library. The poster will feature data visualizations and summarize highlights, which the presenters will expand upon when presenting in person based on the audience’s particular needs/interests. We hope this poster presentation will both aid and inspire other library managers to undertake similar work related to optimizing library hours, employee scheduling, and front-line staffing levels.

description: Three environmental factors of irradiance, solar spectral irradiance distribution and module
temperature greatly affect the performances of photovoltaic (PV) modules. So energy rating given by an actual
electrical energy generated by PV modules is appropriate for the rating of PV modules. However, energy rating is
complicate because energy rating needs actual operation data of PV modules and environmental factors where the PV
modules are installed. Thus, we focused on basic meteorological data (BMD) announced by Japan Meteorological
Agency (JMA). If the environmental factors can be estimated from the BMD announced by meteorological
observatory in each region, the performance of PV modules in each region can be estimated easily. In this study, the
performances of PV modules were estimated from the estimation of the occurrence rate of environmental factors from
BMD in each region. To estimate the occurrence rate of the environmental factors in each region from the BMD, a
relationship between hourly measured BMD and environmental factors were analyzed. Here, the measurement data in
2005 year at Kusatsu city, Shiga prefecture, Japan (34o58’N, 135o57’E) was used. The occurrence rate of the
environmental factors from 2005 to 2007 year in Shiga prefecture each year was estimated by hourly BMD. The
BMD announced by the meteorological observatory at Hikone city (35°17'N, 136°15'E) and the relationship the
BMD and the environmental factors were used to this estimation. Hikone city is environs of Kusatsu city.
Furthermore, the weighted means of performances of bulk type (multi-crystalline Si (mc-Si)) and thin-film type (a-
Si/micro-crystalline Si (Tandem)) PV modules were calculated by the estimated occurrence rate of the environmental
factors. As a result, errors between the estimation and actual performances in the mc-Si module and Tandem in 2005
were within 0.5 %. This methodology can be useful for the rating of the performance of PV modules in Shiga
prefecture.

The new possibilities of obtaining and storing data facilitate deeper analysis of the entire social network, extracted social groups and single individuals as well. One of the most interesting research topic is the network dynamics and dynamics of social groups in particular, it means analysis of group evolution over time. It is the natural step forward after social community extraction. Having communities extracted, appropriate knowledge and methods for dynamic analysis may be applied in order to identify changes as well as to predict the future of all or some selected groups. Furthermore, knowing the most probably change of a given group some additional steps may be performed in order to change this predicted future according to specific needs. Such ability would be a powerful tool in the hands of human resource managers, personnel recruitment, marketing, telecommunication companies, etc.

description: We present controlled numerical results for the ground state spectral function of the resonant Fermi polaron in three dimensions. We establish the existence of a "dark continuum"---a region of anomalously low spectral weight between the narrow polaron peak and the rest of the spectral continuum. The dark continuum develops when the s-wave scattering length is of the order of the inverse Fermi wavevector, $a\lesssim 1/k_{\rm F}$, i.e. in the absence of a small interaction-related parameter when the spectral weight is not expected to feature a near-perfect gap structure after the polaron peak.

description: Local gravitational theories with more than four derivatives are superrenormalizable, and also may be unitary in the Lee-Wick sense. Thus, it is relevant to study the low-energy properties of these theories, especially to identify observables which might be useful for experimental detection of higher derivatives. Using an analogy with the neutrino Physics, we explore the possibility of a gravitational seesaw mechanism, in which several dimensional parameters of the same order of magnitude produce a hierarchy in the masses of propagating particles. Such a mechanism could make a relatively light degree of freedom detectable in low-energy laboratory and astrophysical observations, such as torsion balance experiments and the bending of light. We demonstrate that such a seesaw mechanism in the six- and more-derivative theories is unable to reduce the lightest mass more than in the simplest four-derivative model. Adding more derivatives to the four-derivative action of gravity makes heavier masses even greater, while the lightest massive ghost is not strongly affected. This fact is favorable for protecting the theory from instabilities, but makes the experimental detection of higher derivatives more difficult.

description: Accuracy in the measurement of solar cell performance attains more and more economic significance additionally to its importance in technology development. Measurement of bare (without additional interconnectors on the bus bars) wafer based silicon solar cells directly in production with a high relative accuracy is important for cell sorting and a high absolute accuracy is necessary for valuation of the product. The calibration of the references used to set the cell testers focuses on the precision of ISC measurement, but for the valuation the maximum power at standard testing conditions is the decisive number. Therefore the fill factor determination is a critical point which depends on the specific implementation of the four wire measurement technique. The paper discuses some contacting geometries in detail and proposes how to measure cell fill factor without interference of the bus bar resistance, because the bus bar is the interface to the cell ambience.

description: We use observed transmission line outage data to make a Markov influence graph that describes the probabilities of transitions between generations of cascading line outages, where each generation of a cascade consists of a single line outage or multiple line outages. The new influence graph defines a Markov chain and generalizes previous influence graphs by including multiple line outages as Markov chain states. The generalized influence graph can reproduce the distribution of cascade size in the utility data. In particular, it can estimate the probabilities of small, medium and large cascades. The influence graph has the key advantage of allowing the effect of mitigations to be analyzed and readily tested, which is not available from the observed data. We exploit the asymptotic properties of the Markov chain to find the lines most involved in large cascades and show how upgrades to these critical lines can reduce the probability of large cascades.

We say that a $3$-uniform hypergraph $H=(V,E)$ is $(d,η)$-quasirandom if for any subset $X\subseteq V$ and every set of pairs $P\subseteq V\times V$ the number of pairs $(x,(y,z))\in X\times P$ with $\{x,y,z\}$ being a hyperedge of $H$ is in the interval $d|X||P|\pmη|V|^3$. We show that for any $\varepsilon>0$ there exists $η>0$ such that every sufficiently large $(1/2+\varepsilon,η)$-quasirandom hypergraph contains a tetrahedron, i.e., four vertices spanning all four hyperedges. A known random construction shows that the density $1/2$ is best possible. This result is closely related to a question of Erdős, whether every weakly quasirandom $3$-uniform hypergraph $H$ with density bigger than $1/2$, i.e., every large subset of vertices induces a hypergraph with density bigger than $1/2$, contains a tetrahedron.

Quantum weak values and logic, an uneasy couple

description: Quantum mechanical weak values of projection operators have been used to answer which-way questions, e.g. to trace which arms in a multiple Mach-Zehnder setup a particle may have traversed from a given initial to a prescribed final state. I show that this procedure might lead to logical inconsistencies in the sense that different methods used to answer composite questions, like Has the particle traversed the way X or the way Y? , may result in different answers depending on which methods are used to find the answer. I illustrate the problem by considering some examples: the quantum pigeonhole framework of Aharonov et al, the three-box problem, and Hardys paradox. To prepare the ground for my main conclusion on the incompatibility in certain cases of weak values and logic, I study the corresponding situation for strong/projective measurements. In this case, no logical inconsistencies occur provided one is always careful in specifying exactly to which ensemble or sample space one refers. My results cast doubts on the utility of quantum weak values in treating cases like the examples mentioned.

description: Les professionnels de santé sont impliqués dans les soins thermaux qu’ils soient médecins, infirmiers ou kinésithérapeutes. D’autres professions pressentent l’intérêt du thermalisme dans l’exercice de leur discipline : sage-femmes, odontologistes, pharmaciens... L’objet de ce travail est d’établir un état des lieux des formations initiales en thermalisme au cours des études de santé et de proposer une offre de formation novatrice en sciences de la santé. La formation réside dans la dispensation d’une culture commune, le développement de compétences transversales nécessaires à tout professionnel souhaitant exercer dans le champ du thermalisme pour être mises à profit dans le périmètre de leur métier. Actuellement, à l’exception de la formation des médecins, les enseignements sont proposés sous forme d’unité d’enseignement optionnelle dans les filières des métiers de la santé. Ces deux options permettent de découvrir le therma- lisme et ses bénéfices dans la prise en charge des patients. Il conviendrait d’envisager une formation d’expertise au sens des accords de Bologne (LMD) pour tous les étudiants des disci- plines de la santé souhaitant développer une véritable expertise en thermalisme, mais aussi promouvoir la recherche et l’innovation.
description: The health professionals are involved in spa treatments, whether they are MD, nurses or physiotherapists. Other professions feel the interest of crenobalneotherapy in the exercise of their discipline: midwives, odontologists, pharmacists... The purpose of this work is to establish an inventory of initial curricula in crenobalneotherapy during health studies and to propose an innovative training in health sciences. The training lies in the dispensation of a common culture, the development of transversal competences necessary to any professional wishing to practice in crenobalneotherapy in their professional practice. At present, except MD training, the proposed curricula is in form of optional modules in other health professions. These two options allow to discover the spa treatment and its benefits in the patients' care. It would be advisable to consider a training of expertise in the light of the Bologna process (LMD) for all students in health disciplines wishing to develop a real expertise in crenobalneotherapy, but also to promote the research and the innovation.

description: We give an example of a scalar second order differential operator in the plane with double periodic coefficients and describe its modification, which causes an additional spectral band in the essential spectrum. The modified operator is obtained by applying to the coefficients a mirror reflection with respect to a vertical or horizontal line. This change gives rise to Rayleigh type waves localized near the line. The results are proven using asymptotic analysis, and they are based on high contrast of the coefficient functions.

Sampling Requirements for Stable Autoregressive Estimation

description: We consider the problem of estimating the parameters of a linear univariate autoregressive model with sub-Gaussian innovations from a limited sequence of consecutive observations. Assuming that the parameters are compressible, we analyze the performance of the $\ell_1$-regularized least squares as well as a greedy estimator of the parameters and characterize the sampling trade-offs required for stable recovery in the non-asymptotic regime. In particular, we show that for a fixed sparsity level, stable recovery of AR parameters is possible when the number of samples scale sub-linearly with the AR order. Our results improve over existing sampling complexity requirements in AR estimation using the LASSO, when the sparsity level scales faster than the square root of the model order. We further derive sufficient conditions on the sparsity level that guarantee the minimax optimality of the $\ell_1$-regularized least squares estimate. Applying these techniques to simulated data as well as real-world datasets from crude oil prices and traffic speed data confirm our predicted theoretical performance gains in terms of estimation accuracy and model selection.

description: Energy rating measurements of PV modules at their actual installation location are the best assessment
for reliable design and performance of PV plants. This approach is too bulky for a preliminary evaluation. We therefore
suggest a solution based on module models and measurements of the environmental parameters at the actual
installation location. This paper analyses two well known maximum power models, based on STC and laboratory
measurements, their outcomes are compared with experimental data in different operating conditions. The results are
generally not satisfactory because of the large spread of solar radiation spectrum. A methodology for the estimation of
maximum power for on-the-field conditions has been investigated and implemented. It is based on PV standard models
and an adaptive artificial neural network for the power errors correction. The satisfactory results have suggested the
definition of an algorithm for measuring the diffused radiation without the need of a shadowing ring. The on-the-field
measurements of direct and diffused radiations and the power correction model have been merged in the design of a
system for the estimation of the maximum power of any module in any place. The system (Gallo fotovoltaico) consists
of two major parts: the system installed at our Department for the evaluation of models and the training of the power
correction model and the self powered device for on-the-field environmental measurements. The system can therefore
estimate the maximum power and energy rating in any actual operating condition.

description: Young technology-based firms are widely recognised as important drivers of economic renewal and growth. Many statistical studies have been carried out to ascertain the attributes of the more successful ventures. Most studies are based associations between measures of firms’ growth and other firms’ attributes, taken out of context. The internal developmental processes of these new ventures, viewed holistically, have not received attention in the research literature. Cross-sectional analyses of variance cannot reveal cumulative dynamic processes at work within firms, while case studies on new firms have lacked a generic conceptual framework capable of providing a systematic basis for comparison. This report aims to complement findings from the dominant research approach by explicitly addressing new firms' internal development processes. To summarise unfolding growth experience over time in new firms, a quantitative analysis has been conducted on an exploratory basis. A new data set was created tracing over a period of eight years, the growth of a cohort of 136 German technology-based firms incorporated in 1991/9 . New compression techniques were devised that preserve information on internal change over time within firms. This analysis provides a quantitative background to an in-depth examination of 15 case studies undertaken to identify internal firm development processes. The analytic framework, inspired by the work of Penrose, provides a systematic way of comparing firms' growth experience. An exemplar is provided here together with an exposition of the conceptual framework. It is shown that the typical growth paths of even a relatively successful cohort of survivor firms feature growth spurts, growth interruptions and temporary stagnation, evidence of which is concealed in standard studies of aggregate growth rates. The report explores the reasons for these patterns, using detailed case evidence. The ‘new venture development framework’ explains the prevalence of these growth patterns with reference to the entrepreneurs' evolving business concept and the firms' resource base and market opportunities. This pilot study shows that it is possible to understand and compare new firm growth by using contextual observations at the level of the firm. This provides rich material to inform support agencies and entrepreneurs facing growth problems of new firms in the field.

description: Two-dimensional molybdenum disulfide (MoS$_2$) featuring atomically thin thickness and unique electronic structure with favorable bandgap has been widely recognized as an attractive new material for the development of the next generation of ultra-compact, light-weight optoelectronic components. In parallel, the recently emerged metasurfaces have demonstrated exceptional controllability over electromagnetic field within ultra-compact subwavelength dimension offering an unprecedented approach to improve the performance of optoelectronic devices. In this work, we are proposing an integration of metasurfaces with 2D semiconductor materials to achieve polarization sensitive, fast-response photodetectors. The reported devices are among the most compact hybrid MoS2-gap-plasmon metasurface detectors. Relying on the significant electromagnetic field confinement provided by the metasurfaces to enhance light absorption and to reduce the surface states, which generally limit the photo-generated carriers lifetime, we measured enhanced photocurrent and a fast detection speed. Moreover, the strong optical anisotropy introduced by the metasurfaces is used to efficiently control the polarization sensitivity of the photodetector. This work provides a feasible and effective solution to improve the performance of two-dimensional materials based photodetectors.
