description: This paper analyzes the cumulative grid feed-in behavior of distributed PV battery systems.
Simulations with a time resolution of 1 s were performed to determine the impact of the feed-in limit and respective
moving average interval on the power flows fed into the grid by spatially dispersed PV battery systems. The study
focuses on the main question: What is the impact of different averaging intervals on the grid feed-in behavior of a
distributed fleet of PV battery systems? The simulation results reveal that the peaks in the overall feed-in power can
be mitigated by reducing the averaging interval from 10 min to 1 min or less.

description: This study investigates how Chinese American children construct their identities in self-created multimodal discourses. Drawing from multimodal discourse and critical visual literacy, the research analyzes multimodal discourses created by eight Chinese American children, including the illustrations, texts, and oral explanations. The findings reveal that these children construct dual representations of identity—depicting themselves as both ordinary and distinctive. These portrayals simultaneously align with and challenge stereotypical depictions of Chinese Americans in dominant society, underscoring the need for diverse and pluralistic representations of people and culture.

description: Most photovoltaic (PV) string inverters have the hardware capability to measure at least part of the
current-voltage (I-V) characteristic curve of the PV strings connected at the input. However, this intrinsic capability of
the inverters is not used, since I-V curve measurement and monitoring functions are not implemented in the inverter
control software. In this paper, we aim to show how such a functionality can be useful for PV system monitoring
purposes, to detect the presence and cause of power-loss in the PV strings, be it due to shading, degradation of the PV
modules or balance-of-system components through increased series resistance losses, or shunting of the PV modules.
To achieve this, we propose and experimentally demonstrate three complementary PV system monitoring methods that
make use of the I-V curve measurement capability of a commercial string inverter. The first method is suitable for
monitoring single or independent PV strings, and is based on evaluating the ratio of certain operation points on the
string I-V curve. The second method is applicable to PV systems with identical strings, and is based on monitoring and
inter-comparison of string I-V curve parameters. For PV systems with non-identical strings, or when all strings can be
affected by faults, we propose to use in-plane irradiance and module temperature measurements, and a performance
model of the PV strings, to predict the optimal string I-V curve parameters, and then perform the inter-comparison with
the measured values, to identify the cause of the faults.

description: One of the most popular time-frequency representation is certainly the Wigner distribution. To reduce the interferences coming from its quadratic nature, several related distributions have been proposed, among which the so-called Born-Jordan distribution. It is well known that in the Born-Jordan distribution the ghost frequencies are in fact damped quite well, and the noise is in general reduced. However, the horizontal and vertical directions escape from this general smoothing effect, so that the interferences arranged along these directions are in general kept. Whereas these features are graphically evident on examples and heuristically well understood in the engineering community, there is not at present a mathematical explanation of these phenomena, valid for general signals in L^2 and, more in general, in the space S' of temperate distributions. In the present note we provide such a rigorous study using the notion of wave-front set of a distribution. We use techniques from Time-frequency Analysis, such as the modulation and Wiener amalgam spaces, and also results of microlocal regularity of linear partial differential operators.

description: Temporarily Captured Orbiters (TCOs) are Near-Earth Objects (NEOs) which make a few orbits of Earth before returning to heliocentric orbits. Only one TCO has been observed to date, 2006 RH120, captured by Earth for one year before escaping. Detailed modeling predicts capture should occur from the NEO population predominantly through the Sun-Earth L1 and L2 points, with 1% of TCOs impacting Earth and approximately 0.1% of meteoroids being TCOs. Although thousands of meteoroid orbits have been measured, none until now have conclusively exhibited TCO behaviour, largely due to difficulties in measuring initial meteoroid speed with sufficient precision. We report on a precise meteor observation of January 13, 2014 by a new generation of all-sky fireball digital camera systems operated in the Czech Republic as part of the European Fireball Network, providing the lowest natural object entry speed observed in decades long monitoring by networks world-wide. Modeling atmospheric deceleration and fragmentation yields an initial mass of ~5 kg and diameter of 15 cm, with a maximum Earth-relative velocity just over 11.0 km/s. Spectral observations prove its natural origin. Back-integration across observational uncertainties yields a 92 - 98% probability of TCO behaviour, with close lunar dynamical interaction. The capture duration varies across observational uncertainties from 48 days to 5+ years. We also report on two low-speed impacts recorded by US Government sensors, and we examine Prairie Network event PN39078 from 1965 having an extremely low entry speed of 10.9 km/s. In these cases uncertainties in measurement and origin make TCO designation uncertain.

description: In weed control, precision agriculture can help to greatly reduce the use of herbicides, resulting in both economical and ecological benefits. A key element is the ability to locate and segment all the plants from image data. Modern instance segmentation techniques can achieve this, however, training such systems requires large amounts of hand-labelled data which is expensive and laborious to obtain. Weakly supervised training can help to greatly reduce labelling efforts and costs. We propose panoptic one-click segmentation, an efficient and accurate offline tool to produce pseudo-labels from click inputs which reduces labelling effort. Our approach jointly estimates the pixel-wise location of all N objects in the scene, compared to traditional approaches which iterate independently through all N objects; this greatly reduces training time. Using just 10% of the data to train our panoptic one-click segmentation approach yields 68.1% and 68.8% mean object intersection over union (IoU) on challenging sugar beet and corn image data respectively, providing comparable performance to traditional one-click approaches while being approximately 12 times faster to train. We demonstrate the applicability of our system by generating pseudo-labels from clicks on the remaining 90% of the data. These pseudo-labels are then used to train Mask R-CNN, in a semi-supervised manner, improving the absolute performance (of mean foreground IoU) by 9.4 and 7.9 points for sugar beet and corn data respectively. Finally, we show that our technique can recover missed clicks during annotation outlining a further benefit over traditional approaches.

description: Short-term variability in the power generated by large grid-connected PV plants
can negatively affect power quality and the network stability. New grid-codes require
combining the PV generator with some form of energy storage technology in order to reduce
short-term PV power fluctuations. An already existing PV plant has been adapted for the
installation of a 100 kW/56 kWh Lithium-¬ion battery, in order to validate several ramp-rate
control strategies previously designed and simulated in Mathlab. This work explains, therefore,
the validation process carried on four different strategies along several days in a real
environment.

description: Excerpts from the report: The Yampa River Basin is located in northwest Colorado and south-central Wyoming. The Colorado portion contains most of Moffat and Routt counties and small parts of Rio Blanco, Garfield, and Grand counties. In Wyoming it comprises parts of Carbon and Sweetwater counties. The Red Desert Basin is the northern boundary, the Continental Divide the eastern boundary in both states, the divide between the White and Yampa rivers the southern boundary, and the Utah-Colorado state line is the western boundary. The Utah-Colorado state line is not a natural basin boundary, but it is used to complete the Colorado western slope studies. The basin land area is approximately 2,811 square miles in Wyoming and 6,719 square miles in Colorado, for a total of 9,530 square miles. The basin is 128 miles long from west to east and averages 75 miles in width. This report presents information on water and related land resources of the Yampa River Basin in the states of Colorado and Wyoming. The principal objective of this study was the collection and development of information on water and related land resource use and management with particular regard to multiple use, to provide a basis for coordinating USDA programs of watershed protection, flood prevention, land and water management, fish and wildlife development, recreational development, municipal and industrial water development with the related activities of local, State, and other Federal agencies.

description: We present a detailed study of the complex ionization structure in a small (~250 pc) extended narrow line region (ENLR) cloud near Centaurus A using the Multi Unit Spectroscopic Explorer. This cloud is located in the so-called outer filament of ionized gas (about 15 kpc from the nucleus) where jet-induced star formation has been suggested to occur by different studies. We find that, despite the small size, a mixture of ionization mechanisms is operating, resulting in considerable complexity in the spatial ionization structure. The area includes two H II regions where star formation is occurring and another location where star formation must have ceased very recently. Interestingly, the extreme Balmer decrement of one of the star forming regions (H_alpha/H_beta~6) indicates that it is still heavily embedded in its natal cocoon of gas and dust. At all three locations a continuum counterpart is found with spectra matching those of O/B stars local to Centaurus A. The H II regions are embedded in a larger gas complex which is photoionized by the radiation of the central active galactic nucleus (AGN), but the O/B stars affect the spatial ionization pattern in the ENLR cloud very locally. In particular, in the surroundings of the youngest star forming region, we can isolate a tight mixing sequence in the diagnostic diagram going from gas with ionization due to a pure stellar continuum to gas only photoionized by the AGN. These results emphasize the complexity and the mixture of processes occurring in star forming regions under the influence of an AGN radiation. This is relevant for our understanding of AGN-induced star formation suggested to occur in a number of objects, including this region of Centaurus A. They also illustrate that these young stars influence the gas over only a limited region.

description: Extending results of Humpherys-Lyng-Zumbrun in the one-dimensional case, we use a combination of asymptotic ODE estimates and numerical Evans-function computations to examine the multidimensional stability of planar Navier--Stokes shocks across the full range of shock amplitudes, including the infinite-amplitude limit, for monatomic or diatomic ideal gas equations of state and viscosity and heat conduction coefficients $μ$, $μ+η$, and $ν=κ/c_v$ in the physical ratios predicted by statistical mechanics, with Mach number $M>1.035$. Our results indicate unconditional stability within the parameter range considered; this agrees with the results of Erpenbeck and Majda for the corresponding inviscid case of Euler shocks. Notably, this study includes the first successful numerical computation of an Evans function associated with the multidimensional stability of a viscous shock wave. The methods introduced may be used in principle to decide stability for any $γ$-law gas, $γ>1$, and arbitrary $μ>|η|\ge 0$, $ν>0$ or, indeed, for shocks of much more general models and equations, including in particular viscoelasticity, combustion, and magnetohydrodynamics (MHD).

description: The significant enlargement of the functionalities of the SunSniffer PV monitoring system is the
objective of a German joint research project. The SunSniffer technology has already realized the approach of a
module based PV monitoring. Essential project targets are the integration of a PV yield simulation engine, the
significant enhancement of the error detection sensitivity via continuous nominal-actural value comparisons, an
automated fault analysis, automated recommendations for action (swapping of modules, module cleaning etc.) based
on ROI considerations, and the automated prediction of an imminent PV plant performance deterioration. The
previous project work was focused on the integration of the simulation engine, the development of the automated
error detection, and the development of the automated fault analysis. First the accuracy of the selected PV yield
simulation engine was investigated. It was demonstrated that the simulation accuracy can attain values down to
0.4 %. Concerning the automated fault analysis the approach was to develop an algorithm that continuously analyzes
the measured module voltage und string current data by means of pattern matching. As example a feasible approach
to distinguish between PID and partial shadowing was shown.

description: Understanding the limiting behavior of eigenvalues of random matrices is the central problem of random matrix theory. Classical limit results are known for many models, and there has been significant recent progress in obtaining more quantitative, non-asymptotic results. In this paper, we describe a systematic approach to bounding rates of convergence and proving tail inequalities for the empirical spectral measures of a wide variety of random matrix ensembles. We illustrate the approach by proving asymptotically almost sure rates of convergence of the empirical spectral measure in the following ensembles: Wigner matrices, Wishart matrices, Haar-distributed matrices from the compact classical groups, powers of Haar matrices, randomized sums and random compressions of Hermitian matrices, a random matrix model for the Hamiltonians of quantum spin glasses, and finally the complex Ginibre ensemble. Many of the results appeared previously and are being collected and described here as illustrations of the general method; however, some details (particularly in the Wigner and Wishart cases) are new. Our approach makes use of techniques from probability in Banach spaces, in particular concentration of measure and bounds for suprema of stochastic processes, in combination with more classical tools from matrix analysis, approximation theory, and Fourier analysis. It is highly flexible, as evidenced by the broad list of examples. It is moreover based largely on "soft" methods, and involves little hard analysis.

description: The increased use of grid connected photovoltaic (PV) systems in low voltage (LV) grids also raises
concern regarding the effects of these new generation units on the grid operation. Overvoltage in LV grids during
high PV generation periods is one of the well-known effects caused by PV systems, which potentially can decrease
the PV hosting capacity of electric grids. This paper presents the applications of medium voltage to low voltage
(MV/LV) transformers with on-load tap changers (OLTCs) to prevent overvoltage in high PV penetration conditions.
Autonomous methods for controlling the operation of OLTC during high PV generation periods are investigated and
the methods are applied to an LV feeder with an MV/LV transformer equipped by OLTC located in Felsberg,
Germany. The potential interferences between OLTCs and two other overvoltage prevention methods, the demand
side management (DSM) and the reactive power absorption by PV inverters, are investigated using field test results
and simulations performed on the mentioned LV grid. The results show that the application of OLTC can effectively
increase the PV hosting capacity of the grid.

description: Bis zu einem Drittel der gesamten Bevölkerung der Schweiz leidet im Laufe eines Jahres an einer psychischen Erkrankung. Ein Grossteil der Betroffenen ist erwerbstätig. Untersuchungen zeigen dementsprechend auf, dass Führungskräfte häufig mit psychisch auffälligen Arbeitnehmenden in Kontakt kommen. Ungeachtet dessen, erkennen sie die Schwierigkeiten der Betroffenen oft zu spät und bringen sie nicht mit einer psychischen Erkrankung in Verbindung. Zudem sind Führungskräfte im Umgang mit den erkrankten Arbeitnehmenden meist überfordert, während Arbeitnehmende Stigmatisierung und Kündigung befürchten. Im Krankheitsverlauf kommt es deshalb schon früh zu interpersonellen Schwierigkeiten am Arbeitsplatz. Schlussendlich dient den Arbeitgebenden die Kündigung der betroffenen Mitarbeitenden in einem Grossteil der Fälle als Problemlösung. In der vorliegenden Literaturarbeit wird der Frage nachgegangen, welchen Beitrag die Betriebliche Soziale Arbeit an Früherkennung und Frühintervention bei psychisch erkrankten Mitarbeiter*innen leisten kann. Ausgangspunkt bildet die Auseinandersetzung mit psychischer Erkrankung und Belastung sowie die theoretische Einordnung der Früherkennung und Frühintervention. Anhand verschiedener Studien werden die Auswirkungen auf die Arbeitsbeziehungen aufgezeigt und die Interventionen und Problemlösungsversuche der Führungskräfte beleuchtet. Anhand eines Modells aus dem betrieblichen Gesundheitsmanagement und Beispielen aus Unternehmen wird aufgezeigt, welche Früherkennungs- und Frühinterventionsmassnahmen in der Praxis umgesetzt werden. Im Anschluss werden Handlungsempfehlungen für die Betriebliche Soziale Arbeit im Rahmen der Früherkennung und Frühintervention formuliert. Früherkennung und Frühintervention ist von entscheidender Bedeutung, sollen psychisch erkrankte Personen im Arbeitsmarkt gehalten und die Belastung aller Beteiligten reduziert werden.

description: Reverse and stable bipolar resistive switching effect was observed in planar NdCeCuO - NdCeO - Ag heterostructures. It was shown that the current voltage charactereriscs of the BRSE observed has a diode character. Simulations were used to consider the influence of the nonuniform distribution of an electric field at the interface of a heterojunction on the effect of bipolar resistive switching in investigated structures. The inhomogeneous distribution of the electric field near the contact edge creates regions of higher electric field strength which, in turn, stimulates motion and redistribution of defects, changes of the resistive properties of the whole structure and formation of a percolation channel.

description: Objective: To describe the growth dynamics of fetuses with initial fetal growth restriction (FGR) later outgrowing the 10th centile for estimated fetal weight with respect to perinatal outcomes and maternal factors.Methods: A multicenter prospective study recruited 1116 patients for ultrasound surveillance between 2010 and 2012. All pregnancies were growth-restricted singleton gestations between 24 + 0 and 36 + 0 weeks. Biometry and Doppler analysis were carried out, and delivery and adverse perinatal outcomes were recorded.Results: A total of 193 (17%) fetuses outgrew their diagnosis of initial FGR (surpassed the 10th centile) on their last sonogram before delivery. These fetuses were termed “growers,” to compare with the true FGR group. The mothers of “growers” were less likely to be smokers (14% vs 25%, P = 0.0001) or affected by hypertensive pregnancy complications (5.2% vs 15%, P = 0.001). Of the growers, 49 (25%) had an abnormal umbilical artery Doppler; however, in most cases (33/49, 67%), this was a single epi?sode of raised umbilical artery pulsatility index, which subsequently normalized.Conclusion: There were dynamic growth changes in FGR fetuses, with 17% out?growing their original diagnosis. Positive growth spurts more commonly occurred in healthy mothers. Once a fetus had outgrown the 10th centile, antenatal surveillance could be decreased.

Um die unterschiedlichen Perspektiven zu erfassen, wurden mit Fachpersonen von zwei verschiedenen Institutionen Leitfadeninterviews durchgeführt. Die Perspektiven der Jugendlichen wurden über Gruppendiskussionen in den gleichen Institutionen erhoben. Die Auswertung der Interviewinhalte erfolgte nach der qualitativen Inhaltsanalyse von Mayring. Die Ergebnisse der Auswertung wurden mit den erarbeiteten Theorieinhalten verknüpft. Die zu Beginn formulierten Fragestellungen liessen sich beantworten und Handlungsempfehlungen für die Praxis konnten ausgearbeitet werden. Diese Bachelorarbeit gibt über den Ursprung und die Gründe für herausfordernde Verhaltensweisen Auskunft, erschliesst Möglichkeiten für einen professionellen Umgang und unterstützt Professionelle dabei, diese Herausforderung im Alltag zu meistern. Dabei werden die Perspektiven der Jugendlichen in die Erkenntnisse miteinbezogen.

description: Quantifying the photovoltaic (PV) energy yield is subject to several uncertainties introduced by the
different elements in the PV energy conversion chain. Project developers and investors need clear statements when
up-front evaluating the financial profitability and risk of a PV investment. Once the plant is in operation, owners,
asset managers and O&M contractors monitor its performance. They want to operate and maintain their portfolios
efficiently. Hence, they need unambiguous performance indicators that can trigger alarms reliably. For both purposes,
reliable uncertainty measures are essential. The uncertainties introduced by the different elements in the PV energy
conversion chain are reviewed in this paper, based on literature and field experience and typical values for practical
application are provided. This paper recommends clear guidelines for uncertainty assessment in PV modelling and
monitoring of grid-connected PV systems. It offers guidance on the correct combination and propagation of the
different uncertainties affecting both PV modelling and the monitoring of PV systems.

description: Variable-step algorithms have gained interest in recent years due to their ability to overcome wellknown
trade-off between steady-state oscillations and fast dynamics related to the fixed-step perturbative algorithms.
Although, the optimization of fixed-step algorithms has been investigated thoroughly in previous studies, there is not
much research done related to the variable-step algorithms in changing irradiance conditions. It has been shown in
this paper that variable-step perturbative algorithms are very sensitive to drift when maximum-power-point (MPP)
tracker operates in varying irradiance conditions. The origin of the problem is the same as in fixed-step algorithms -
the algorithm cannot distinguish the perturbed power change from power change caused by the variation in
irradiance. The existence of drift problem in variable-step perturbative algorithms is shown to be valid by extensive
simulations and experimental results and it should be taken into account in variable-step MPPT algorithm design.
Moreover, a couple of solutions are proposed to overcome this problem.

description: Under partial shading conditions, several power peaks (maximum power points - MPPs) are presented
on the P-V curve of a photovoltaic system, hindering the effectiveness of typical maximum power point tracking
(MPPT) algorithms, due to possible convergence to a local suboptimal MPP. In this paper, a global MPPT (GMPPT)
method for PV strings is proposed, which exploits the theoretical MPP characterization to detect the shading conditions
and estimate all MPPs on the P-V curve. The calculations performed do not involve unnecessary operating point
variations and output power fluctuations. The proposed method is designed for PV strings illuminated at two irradiance
levels and only needs the standard voltage and current sensors of the DC/DC converter.

description: The purpose of the work is the evaluation of Tigo Optimizer benefits on the performances of a thin film PV plant.
The experimental activity consists in a side by side test of two strings (with and without Tigo optimizers) to compare
their energy yield in different operating conditions. The activity has the aim to test and assess the best solutions to
increase the performances and reduce LCOE of PV plants, minimizing mismatch effect that can be caused by several
factors. The first results of the experimental activity show a gain in the sub-field with Tigo optimizers in a range of 2-
4%. In order to assess potential benefit of Tigo optimizers on a utility-scale application, an analysis on existing PV
plants has been carried out, from which the real mismatch measured on field has been estimated; finally an
economical analysis has been carried out to evaluate the conditions of the PV plants, in terms of potential gain, in
which the installation of the optimized solution can be a convenient investment.

description: In this deliverable D6.1, we describe the review of innovative sensors technology in the Co-UDlabs project and give details about the 8 selected sensors and the envisioned plan to test their performance. We applied a three-phased approach, where we first generated a comprehensive list of 55 sensors and digital monitoring technologies, e.g., data transmission and energy harvesting, which had a strong focus on online water quality monitoring. This list was subsequently narrowed down to a final list of 8 sensors which measure, i) coliforms continuously with in-situ fluorescence, ii) electrical conductivity with low-power, iii) water velocities with cameras, iv) NH4 and other pollutants with a submersible spectrophotometer, v) multiple pollutants with hyperspectral imaging, vi) polycyclic aromatic hydrocarbons PAH with in-situ fluorescence, vii) pipe condition, and viii) 3D sediment beds with LiDAR. Of those 8 instruments, 4 have a low technology readiness level (TRL) and have been selected for their potential to advance urban drainage research. In contrast, 3 other sensors have a TRL of 8 or higher, which means that, if tests are successful, they could readily be integrated into new monitoring services. In summary, we achieved a satisfactory balance between monitoring technology with the potential to advance urban drainage research and technology which can directly deliver added value to practitioners. The final list of selected sensors is of special interest for work package (WP) 6 and WP9, to provide smart monitoring solutions and inform the transnational access activities. It provides the necessary input for Task 6.1.2. to test the sensors in the laboratory and under real-world conditions. It directly contributes to addressing the project goals defined in objectives No. 6.2 and 6.3 of the project proposal, as well as Main Objective 3, and to a lesser degree to objectives No. 2.2 and Main Objective 2.

description: Cardiac amyloidosis (CA) is often overlooked or misdiagnosed. Effects of growing disease awareness, diagnostic ameliorations and novel treatment options on CA diagnosis and management are scarcely reported. To report trends in diagnosis, referral routes, clinical presentation, early onset diagnostic red flags and outcome in de novo CA subjects. An unselected cohort of 139 de novo CA patients over an 8-year period in a tertiary referral hospital was recruited. Transthyretin (ATTR, 82%, n = 114) was the most common CA form; Light-chain (AL, 15%, n = 21) and secondary (AA, 3%, n = 4) are less prevalent. Increased awareness over time led to a marked ATTR diagnostic surge, steep non-invasive diagnostic approach increment and increased nuclear medicine and external cardiologist referrals (all p < 0.001). A total of 41% (n = 57/139) of patients were referred by non-cardiology specialist disciplines. Specific referral to rule out CA (24–36%) and diagnostic time lag from symptom onset (9 ± 12 to 8 ± 14 months), however, did not improve (all p > 0.050). Multiple early red flag events preceded CA diagnose several years in ATTR: Left ventricular hypertrophy (LVH, 60%, 4.9 ± 4.3 y), heart failure (54%, 2.5 ± 3.5 y), atrial fibrillation (47%, 5.9 ± 6.7 y), bilateral carpal tunnel syndrome (43%, 9.5 ± 5.7 y) and spinal stenosis (40%, 7.4 ± 6.5 y). LVH ≥ 12 mm was absent in 11% ATTR (n = 13/114) and 5% AL (n = 1/21) patients. Hypertension was common in both ATTR (n = 70/114, 62%) and AL (n = 10/21, 48%). 56% (n = 78/139) of CA presented with heart failure. Cumulative 1 and 5-year mortality of 10%/66%, 40%/52% and 75%/75% for ATTR, AL, and AA, respectively, remains high. Although CA diagnostic uptake and referral improve, specialist-specific disease and diagnostic red flag ignorance result in non-timely diagnosis and unfavourable outcome.
Asymptotically Optimal Distributed Channel Allocation: a Competitive Game-Theoretic Approach

description: In this paper we consider the problem of distributed channel allocation in large networks under the frequency-selective interference channel. Performance is measured by the weighted sum of achievable rates. First we present a natural non-cooperative game theoretic formulation for this problem. It is shown that, when interference is sufficiently strong, this game has a pure price of anarchy approaching infinity with high probability, and there is an asymptotically increasing number of equilibria with the worst performance. Then we propose a novel non-cooperative M Frequency-Selective Interference Game (M-FSIG), where users limit their utility such that it is greater than zero only for their M best channels, and equal for them. We show that the M-FSIG exhibits, with high probability, an increasing number of optimal pure Nash equilibria and no bad equilibria. Consequently, the pure price of anarchy converges to one in probability in any interference regime. In order to exploit these results algorithmically we propose a modified Fictitious Play algorithm that can be implemented distributedly. We carry out simulations that show its fast convergence to the proven pure Nash equilibria.

description: Precise and reliable measurements of the masses and radii of neutron stars with a variety of masses would provide valuable guidance for improving models of the properties of cold matter with densities above the saturation density of nuclear matter. Several different approaches for measuring the masses and radii of neutron stars have been tried or proposed, including analyzing the X-ray fluxes and spectra of the emission from neutron stars in quiescent low-mass X-ray binary systems and thermonuclear burst sources; fitting the energy-dependent X-ray waveforms of rotation-powered millisecond pulsars, burst oscillations with millisecond periods, and accretion-powered millisecond pulsars; and modeling the gravitational radiation waveforms of coalescing double neutron star and neutron star -- black hole binary systems. We describe the strengths and weaknesses of these approaches, most of which currently have substantial systematic errors, and discuss the prospects for decreasing the systematic errors in each method.
