description: The generalized Euler case (rigid body rotation over the fixed point) is discussed here: - the center of masses of non-symmetric rigid body is assumed to be located at the equatorial plane on axis Oy which is perpendicular to the main principal axis Ox of inertia at the fixed point. Such a case was presented in the rotating coordinate system, in a frame of reference fixed in the rotating body for the case of rotation over the fixed point (at given initial conditions). In our derivation, we have represented the generalized Euler case in the fixed Cartesian coordinate system; so, the motivation of our ansatz is to elegantly transform the proper components of the previously presented solution from one (rotating) coordinate system to another (fixed) Cartesian coordinates. Besides, we have obtained an elegantly analytical case of general type of rotations; also, we have presented it in the fixed Cartesian coordinate system via Euler angles.

description: As a possible root cause of significant power loss in photovoltaic systems, the potential induced
degradation (PID) is subjected to intense investigations among the photovoltaic community. An empirical
acceleration model which predicts the power loss due to PID for p-type c-Si based modules has been presented in our
previous publication. In the present work, we publish a model that quantifies not only the degradation but also the
regeneration. The different conditions in the laboratory (full-surface grounding) and in the field (frame grounding)
are considered as well. Ultimately, a realistic simulation of the PID effect under field conditions is obtained. The
outcome underlines the role of the moisture film and its electrical conductivity.

description: The excitations of the Heisenberg antiferromagnetic spin chain in zero field are known as spinons. As pairwise-created fractionalized excitations, spinons are important in the understanding of inelastic neutron scattering experiments in (quasi) one-dimensional materials. In the present work, we consider the real space-time dynamics of spinons originating from a local spin flip on the antiferromagnetic ground state of the (an)isotropic Heisenberg spin-1/2 model and the Babujan-Takhtajan spin-1 model. By utilizing algebraic Bethe ansatz methods at finite system size to compute the expectation value of the local magnetization and spin-spin correlations, spinons are visualized as propagating domain walls in the antiferromagnetic spin ordering with anisotropy dependent behavior. The spin-spin correlation after the spin flip displays a light cone, satisfying the Lieb-Robinson bound for the propagation of correlations at the spinon velocity.

description: We present near-IR (1.1-2.4 micron) position-position-velocity cubes of the 500-year-old Orion BN/KL explosive outflow with spatial resolution 1" and spectral resolution 86 km/s. We construct integrated intensity maps free of continuum sources of 15 H2 and [Fe II] lines while preserving kinematic information of individual outflow features. Included in the detected H2 lines are the 1-0 S(1) and 1-0 Q(3) transitions, allowing extinction measurements across the outflow. Additionally, we present dereddened flux ratios for over two dozen outflow features to allow for the characterization of the true excitation conditions of the BN/KL outflow. All ratios show the dominance of shock excitation of the H2 emission, although some features exhibit signs of fluorescent excitation from stellar radiation or J-type shocks. We also detect tracers of the PDR/ionization front north of the Trapezium stars in [O I] and [Fe II] and analyze other observed outflows not associated with the BN/KL outflow.

description: Electrochemical corrosion is known to degrade solar cells during artificial and outdoor weathering. The
combination of humidity and acetic acid in combination with leakage currents lead to corrosion of the contact fingers
of the solar cells. The polyolefin backsheet shows an extraordinary behavior. The transmission rate of water through
PO is 4x lower than through PET. On the other hand the acetic acid transmission rate through PO is 70x larger than
PET. This leads to lower water content and lower acetic acid concentration in the module. Additionally the low PID
EVA reduces the leakage current. By the combination of both films the module lifetime is guaranteed with low power
degradation.

description: Only high reliability and stability of a thin-film module ensures a good energy yield during its lifetime.
Obviously the actual standards (IEC 61646, IEC 61730-2 and IEC draft 62804 for only c-Si) are insufficient,
considering that returns from the field as well as laboratory test results (beyond IEC-testing) show degradation of IEC
certified modules. Accordingly, also thin-film modules can show degradation effects due to Potential Induced
Degradation (PID), such as TCO-Corrosion and power degradation. This work presents results obtained with thinfilm
modules under Bias-Damp-Heat (BDH) conditions in in- and outdoor tests. To investigate the PID effects, thinfilm
modules are tested in BDH-tests at relevant parameters of humidity and temperature. Variations of the mounting
structure are investigated for μc-Si modules revealing the PID stability of backrail mounted modules. Results with
CIGS modules tested at positive and negative bias with varying humidity show that the polarity is determining the
level of the leakage current but the degradation is driven by other effects.
To evaluate module life-times, in- and outdoor determined leakage currents are compared and analyzed considering
weather data and indoor test results. Finally, module life-times are estimated by simulations basing on the
investigations above.

We fix the parameters so that there is a phase transition (of the van der Waals type) and observe that if the densities at the boundaries are metastable then, after a transient, the system reaches an apparently stationary regime where the current flows from the reservoir with smaller density to the one with larger density.

description: Problems of interest in hydrogeology and hydrocarbon resources involve complex heterogeneous geological formations. Such domains are most accurately represented in reservoir simulations by unstructured computational grids. Finite element methods accurately describe flow on unstructured meshes with complex geometries, and their flexible formulation allows implementation on different grid types. In this work, we consider for the first time the challenging problem of fully compositional three-phase flow in 3D unstructured grids, discretized by any combination of tetrahedra, prisms, and hexahedra. We employ a mass conserving mixed hybrid finite element (MHFE) method to solve for the pressure and flux fields. The transport equations are approximated with a higher-order vertex-based discontinuous Galerkin (DG) discretization. We show that this approach outperforms a face-based implementation of the same polynomial order. These methods are well suited for heterogeneous and fractured reservoirs, because they provide globally continuous pressure and flux fields, while allowing for sharp discontinuities in compositions and saturations. The higher-order accuracy improves the modeling of strongly non-linear flow, such as gravitational and viscous fingering. We review the literature on unstructured reservoir simulation models, and present many examples that consider gravity depletion, water flooding, and gas injection in oil saturated reservoirs. We study convergence rates, mesh sensitivity, and demonstrate the wide applicability of our chosen finite element methods for challenging multiphase flow problems in geometrically complex subsurface media.

description: Reliable determination of the parasitic resistances (series Rs and shunt Rsh resistances) of photovoltaic
(PV) modules is essential for monitoring activities both indoor and outdoor, to evaluate degradation and possibly
identify the reasons thereof. This paper initially presents a qualitative analysis of Rs and Rsh of seven PV module
technologies at different temperatures based on dark current-voltage (IV)- curves. Furthermore, Rs and Rsh are
quantitatively determined applying three different methods: a dark and a light fit procedure of the IV-curves (for Rsh
and Rs) as well as the IEC 60891 procedure as a reference (for Rs only). Crystalline silicon, thin-film and HIT
technologies were investigated at four temperature levels and under different irradiance conditions. In this study, we
discuss the parasitic resistances dependence on module temperature under light and dark conditions. The results are
critically analyzed.
The results show that crystalline modules have lower Rs compared to thin-film technologies. By increasing the
temperature, the Rs in crystalline module increases, while it decreases in thin-film and HIT modules. High Rsh values
are found in all module technologies applying the dark fit method, whereas IV-curves fitting from light measurements
exhibits lower Rsh values. No clear temperature dependence was found for the Rsh.

description: The photoresponse of graphene at mid-infrared frequencies is of high technological interest and is governed by fundamentally different underlying physics than the photoresponse at visible frequencies, as the energy of the photons and substrate phonons involved have comparable energies. Here we perform a spectrally resolved study of the graphene photoresponse for mid-infrared light by measuring spatially resolved photocurrent over a broad frequency range (1000-1600 cm$^{-1}$). We unveil the different mechanisms that give rise to photocurrent generation in graphene on a polar substrate. In particular, we find an enhancement of the photoresponse when the light excites bulk or surface phonons of the SiO$_2$ substrate. This work paves the way for the development of graphene-based mid-infrared thermal sensing technology.

description: Cracks in crystalline solar cells in photovoltaic modules can be caused by applied mechanical loads.
They can lead to efficiency losses and lifetime reduction of the modules. In order to investigate the development of
cracks in encapsulated solar cells, a novel experimental setup was developed that applies loads under well-known
boundary conditions on special test specimens. Those specimens have the same layout of the laminate like
corresponding PV modules. The cells are analyzed by using electroluminescence imaging. Cell cracks are statistically
evaluated and the fracture stresses can be compared directly for different crack orientations or different cell types.
It has been found that the experimental approach can detect very small changes in fracture stresses, which can be
caused by varying processing parameters or by subsequent weathering. So the fracture stress of encapsulated solar
cells can be used as an indicator to investigate changes in the mechanical properties of a PV laminate and its
components, which can be caused by different manufacturing conditions or subsequent weathering. For example an
encapsulant with an increased stiffness leads to a higher probability of failure for the cells in the laminate at a specific
load. The results after weathering showed that thermal cycling and damp heat exposure according to IEC 61215 have
an influence on the fracture stresses for subsequent mechanical loading. Contrary after 4 months of outdoor exposure
under moderate climate conditions in central Germany no significant effect could be measured. This gives some
insight into the occurring effects during weathering, but has to be investigated in future tests with adapted thermal
cycling and outdoor exposure in regions with more extreme temperatures, but it is a hint that the defined accelerated
weathering procedures should be reviewed briefly with correlations to real outdoor behavior.

description: Long term c-Si module degradation can be due to many different physical mechanisms. To discriminate
among them, we have exploited the light IV curves of six modules measured at different stages during 30 years
of module outdoor exposure. To make them comparable, these curves have to be corrected for irradiance and temperature
effects. Since this procedure requires the knowledge of the module series resistance, RSER, value, “pseudo-dark”
IV-curves, obtained by subtracting the photocurrent value from the measured light IV curves, are previously fitted
with an iterative approach using the two diodes model including RSER and shunt resistance, RSH, effects. Applying the
same fitting approach to the “pseudo-dark” IV-curves obtained from the corrected light IV-curves allows performing
a comparison among the values of performance and cell parameters at three different exposure times. For each module,
the most significant variations appear to occur in the fill factor, FF, and RSER values. These variations are not linear
with aging time and the FF variations are inversely correlated to the variations in the RSER value.

description: Parameter estimation for the single diode equivalent circuit model is challenging due to the implicit
transcendental relationship between current and voltage. Various methods for parameter estimation have been
proposed. We compare the performance of the single diode model for several photovoltaic modules with model
parameters determined by applying different methods to a set of IV curves measured outdoors for each module. We
found that a recently-developed sequential estimation method produced calibrated models more reliably, and with
less error, than obtained when using the other estimation techniques we considered. We found that the single diode
equation can be adequately fit to each of a set of IV curves measured over a wide range of conditions. However, the
additional equations, which describe how model parameters change with temperature and irradiance, are the source of
systematic model errors. The sequential estimation method can enable discovery of more appropriate model
equations. We confirmed our findings through analysis of six PV modules representative of a variety of technologies.

description: A full scale methodology for the investigation on the origin and evolution of different defects found in
PV modules, as yellowing, shunts or snail trails has been developed at CENER. The comprehensive method begins at
the module level and steps down to the chemical analysis, in order to figure out the impact that these anomalies may
have in the electrical generation capacity and in which way they may affect the operative life of the modules. To that
end, a special procedure has been developed to measure the I-V curve (at STC) of individual cells in a laminated
module and also to extract pieces from the module for further analysis. Finally, additional characterization tools
(optical inspection, SEM micrographs and EDX analysis) are applied to cell pieces to identify the presence of
different chemical elements in order to understand the potential physical origin of the studied defects.

description: This work proposes a simple instance retrieval pipeline based on encoding the convolutional features of CNN using the bag of words aggregation scheme (BoW). Assigning each local array of activations in a convolutional layer to a visual word produces an \textit{assignment map}, a compact representation that relates regions of an image with a visual word. We use the assignment map for fast spatial reranking, obtaining object localizations that are used for query expansion. We demonstrate the suitability of the BoW representation based on local CNN features for instance retrieval, achieving competitive performance on the Oxford and Paris buildings benchmarks. We show that our proposed system for CNN feature aggregation with BoW outperforms state-of-the-art techniques using sum pooling at a subset of the challenging TRECVid INS benchmark.

description: In this study, we aim to describe nurse characteristics and environmental factors influencing nurses’ decisions to leave a permanent hospital position for travel nursing during the pandemic. Specifically, we ask: What individual nurse characteristics and intrinsic/extrinsic work environment factors are most frequently associated with the decision to transition from a permanent hospital position to travel nursing?, What are the contextual descriptions of nurses’ experiences during COVID-19 leading to their decision to transition to travel nursing?, How do nurses’ contextual descriptions of their experiences leading to the decision to transition to travel nursing more fully explain the contribution of individual characteristics and work environment factors prior to transitioning?

description: A model for characterizing the solar spectral radiation distribution only using APE value as input
parameter is proposed. Although the uniqueness of the relationship between these parameters has been previously
established there is no expression that allows obtaining the solar spectral curves for each APE value. In this work the
APE values for which this uniqueness works have been checked. For this, the cumulative probability distribution
function for each spectrum has been estimated. Using a data mining technique, named k-means, all these curves have
been clustered in five different groups. In each group a solar spectral cumulative distribution function curve known as
centroid has been estimated; this curve is similar to the rest of the curves gathered in the group. The spectra
distribution per clusters is quite homogeneous. The centroid of each cluster characterizes all curves in the cluster. For
doing the analysis, more than two-hundred-fifty-thousands spectra have been used.
title: Analysis Of Circumstances Leading To Injuries In Elite Football Players

description: Understanding injury mechanisms is key to developing prevention strategies. Information concerning injury mechanisms can be obtained by analysing the sportspecific activities during which injuries occur (i.e., inciting circumstances). Despite the recognition that inciting circumstances are crucial for the understanding of mechanisms of injuries and for the development of injury prevention strategies, there are no summaries of evidence currently available, therefore a systematic review was performed to analyse and summarise the available literature on inciting circumstances in football. From the systematic review it emerged that the studies currently available in the literature used different systems and terminology to report the inciting circumstances, which made summarising the literature and providing information for the development of prevention strategies difficult. Therefore, it seemed essential to develop a standardised classification system to analyse and report inciting circumstances in football which could be used both in research and in professional settings. Ten practitioners and researchers with experience of working in elite football and of conducting research on injury were involved in a modified Nominal Group Technique and such a classification system was developed. Subsequently, the system was utilised to analyse inciting circumstances leading to injury in elite football. A retrospective observational study was conducted to analyse data previously collected by one elite European football club. Inciting circumstances were analysed using videoanalysis and GPS and reported using the classification system previously developed.

description: Within the derivative expansion of conformally reduced gravity, the modified split Ward identities are shown to be compatible with the flow equations if and only if either the anomalous dimension vanishes or the cutoff profile is chosen to be power law. No solutions exist if the Ward identities are incompatible. In the compatible case, a clear reason is found for why Ward identities can still forbid the existence of fixed points; however, for any cutoff profile, a background independent (and parametrisation independent) flow equation is uncovered. Finally, expanding in vertices, the combined equations are shown generically to become either over-constrained or highly redundant beyond the six-point level.

description: We have improved the classic differential technique for local ideality factor analysis along the I-V
curve by adding a correction for the series resistance RS of the PV device. The present paper shows the advantages of
plotting the current dependency of the ideality factor (m-I plots) over the classic m-V plots. For generic crystallinesilicon
(c-Si) modules, RS can be estimated from the linear region of the uncorrected m-I plot. Then, the RS-corrected
m-I plot reveals the local ideality factor behaviour along the I-V curve, in particular in the maximum-power-point
(MPP) region. The improved technique is applicable also to PV technologies with a current-dependent series
resistance RS(I). The signatures of cell mismatch are discussed. We show empirical results from different c-Si PV
types, including modules with back-contact (IBC) and heterojunction (HIT) cells. The methods presented in the paper
may be useful to PV module makers for inline testing and in accelerated degradation experiments.

description: Breast cancer is a prevalent malignancy worldwide, affecting both genders. Understanding the communication between cancer cells and fibroblast cells in the tumor microenvironment (TME) is crucial for developing targeted therapies, especially in triple-negative breast cancer that lack common receptors.2 In this study, we investigated the indirect crosstalk between breast tumor cells (MDA-MB-468) and human foreskin fibroblast (HFF) cells by culturing them alone and in presence of conditioned media (CM) derived from one another. Proliferation was assessed through PCNA expression and MTT assay, epithelial-to-mesenchymal transition (EMT) with vimentin expression, and E-cadherin levels were quantified for and cell-cell adhesion using flow cytometry and immunostaining. Migration rates of the cells were evaluated using wound healing and Boyden chamber assays. The results showed that following exposure to tumor-derived CM, the HFF cells exhibited about 50% decrease in vimentin expression, possibly indicating mesenchymal-epithelial transition (MET), wherein the tumor cells may be secreting factors making fibroblasts become less mobile in the TME. Tumor cells exposed to HFF-derived CM showed a twofold increase in migratory rate and a decrease in E-cadherin expression. These findings suggest that secreted factors from each cell line impact the functional behavior of the other, highlighting the importance of TME interactions in developing targeted therapies.

description: This paper presents a comprehensive comparison between a poly-Si and a-Si/μ-Si thin-film tandem PV
module under outdoor conditions in Greece. Both modules are produced by Greek vertically integrated manufacturing
companies and installed at CRES facilities in a tilt angle close to latitude optimum, facing south. The testing period is
more than a year and thus the influences from climate conditions to module electrical characteristics are recorded too.
The testing setup and the measurement equipment follow the DERlab technical guidelines for long-term outdoor
testing. Our long-term outdoor testing scope, which will continue for several years, is to investigate the performance
of the two different technology PV modules in term of energy yields, efficiency fluctuation, module degradation
evolution and PV modules thermal behavior (with respect to ambient conditions). Last but not least results from the
modules initial stabilizing period is presented too.

description: Rogue waves appearing on deep water or in optical fibres are often modelled by certain breather solutions of the focusing nonlinear Schrödinger (fNLS) equation which are referred to as solitons on finite background (SFBs). A more general modelling of rogue waves can be achieved via the consideration of multiphase, or finite-band, fNLS solutions of whom the standard SFBs and the structures forming due to their collisions represent particular, degenerate, cases. A generalised rogue wave notion then naturally enters as a large-amplitude localised coherent structure occurring within a finite-band fNLS solution. In this paper, we use the winding of real tori to show the mechanism of the appearance of such generalized rogue waves and derive an analytical criterion distinguishing finite-band potentials of the fNLS equation that exhibit generalised rogue waves.

description: Background As more regions approach malaria elimination, understanding how different interventions interact to reduce transmission becomes critical. The Lake Kariba area of Southern Province, Zambia, is part of a multi-country elimination effort and presents a particular challenge as it is an interconnected region of variable transmission intensities. Methods In 2012-13, six rounds of mass-screen-and-treat drug campaigns were carried out in the Lake Kariba region. A spatial dynamical model of malaria transmission in the Lake Kariba area, with transmission and climate modeled at the village scale, was calibrated to the 2012-13 prevalence survey data, with case management rates, insecticide-treated net usage, and drug campaign coverage informed by surveillance. The model was used to simulate the effect of various interventions implemented in 2014-22 on reducing regional transmission, achieving elimination by 2022, and maintaining elimination through 2028. Findings The model captured the spatio-temporal trends of decline and rebound in malaria prevalence in 2012-13 at the village scale. Simulations predicted that elimination required repeated mass drug administrations coupled with simultaneous increase in net usage. Drug campaigns targeted only at high-burden areas were as successful as campaigns covering the entire region. Interpretation Elimination in the Lake Kariba region is possible through coordinating mass drug campaigns with high-coverage vector control. Targeting regional hotspots is a viable alternative to global campaigns when human migration within an interconnected area is responsible for maintaining transmission in low-burden areas.

description: It is shown that Tarski's set of ten axioms for the calculus of relations is independent in the sense that no axiom can be derived from the remaining axioms. It is also shown that by modifying one of Tarski's axioms slightly, and in fact by replacing the right-hand distributive law for relative multiplication with its left-hand version, we arrive at an equivalent set of axioms which is redundant in the sense that one of the axioms, namely the second involution law, is derivable from the other axioms. The set of remaining axioms is independent. Finally, it is shown that if both the left-hand and right-hand distributive laws for relative multiplication are included in the set of axioms, then two of Tarski's other axioms become redundant, namely the second involution law and the distributive law for converse. The set of remaining axioms is independent and equivalent to Tarski's axiom system.
