description: PURPOSE: Early puberty is associated with adverse health outcomes. To identify potential modifiable factors for puberty timing, we examined the associations of prepubertal childhood macronutrient intakes with puberty timing in boys and girls. METHODS: In the Avon Longitudinal Study of Parents and Children, macronutrient intakes at age 6 years were predicted using random intercepts linear regression models of dietary data at 3, 4, 7 (assessed by food frequency questionnaires) and 7.5 years (by 3-day food diaries). Timings of puberty onset (Tanner stage 2 genital or breast (B2) development) and puberty completion (voice breaking (VB) or menarche) were calculated from annual parental and child reports at 8-17 years. Age at peak height velocity (PHV) was derived from repeated height measurements at 5-20 years. Linear regression models were fit to estimate the associations of total energy (TEI) and macronutrient intakes (carbohydrate, fat, protein) with puberty timing traits, adjusting for maternal and infant characteristics. RESULTS: Among 3811 boys, higher TEI, but no macronutrient, was associated with earlier VB. Among 3919 girls, higher TEI was associated with earlier ages at B2, PHV, and menarche. Higher protein intake but not carbohydrate or fat intake (in energy partition models) and substitution of dietary protein for carbohydrate (in nutrient density and residual models) was associated with earlier B2, PHV, and menarche in girls. Findings were not attenuated on additional adjustment for body fat percentage during adolescence. CONCLUSIONS: These findings suggest habitual total energy intakes in children, and protein intakes in girls, as potential modifiable determinants of puberty timing.

description: Although the solar energy is a green energy without pollution, the waste of solar module is still a
problem. Herein we propose a recycle process to recover the materials from crystalline silicon module. A thermal
annealing step with well controlled temperature can separate the glass from module without breaking. The EVA and
Tedlar were separated and burned out at different temperature. The recycled glass was clean, completely, and could
be reused again for solar module encapsulation. The recovered solar cell chips, which were breaking during high
temperature annealing, were etching with hydrochloric acid solution to remove the aluminum back side contact. And
then be etching with hydrofluoric acid solution to remove the silver front contact and SiNx anti-refraction coating
layer. The emitter layer and the back side field layer (Al-BSF) were removed by following alkali solution etching.
Finally a pure silicon material was obtained. The recycle yield of silicon was 62% (base on the textured silicon
weight inside the module) and the purity was ~8N. The copper could be recovered by removing the out skin of tinlead
alloy in further acid etching step. The recycle yield of copper was 85%.

description: We consider the effect of a short antiferromagnetic correlation length $ξ$ on the electronic bandstructure of the underdoped cuprates. Starting with a Fermi-surface topology similar to that detected in magnetic quantum-oscillation experiments, we show that a reduced $ξ$ gives an assymmetric broadening of the quasiparticle dispersion, resulting in simulated ARPES data very similar to those observed in experiment. Predicted features include the presence of `Fermi arcs' close to $a{\bf k}=(π/2,π/2)$, without the need to invoke a d-wave pseudogap order parameter. The statistical variation in the ${\bf k}$-space areas of the reconstructed Fermi surface pockets causes the quantum oscillations to be strongly damped, even in very strong magnetic fields, in agreement with experiment.

description: The masked palm civet (Paguma larvata) (Carnivora: Viverridae) attracted public concern in 2003, when SARS-CoV-like viruses were identified by Guan et al from several individuals from a Shenzhen market . This small carnivore is the only species in the genus of Paguma. The distribution of this species is mainly restricted in subtropical and tropical area of Asia, but it can also be found in several northern province in China, such as Shanxi, Shaanxi, and Tibet. The masked palm civet was found to hibernate slightly during the winter in northern area. Besides, it has been introduced in Japan as an alien species. This species is nocturnal, arboreal and basically solitary. They live in a variety of habitats, including forests, rainforest, parks, fruit orchards, gardens and plantations. They choose habitats largely depends on the food availability. There are 15 subspecies has been classified according to body color and facial pattern , but genetic difference among different populations is low, indicating the need for taxonomic revision for this species.

description: We present the design of the prototype telescope and spectrograph system for the Affordable Multiple Aperture Spectroscopy Explorer (AMASE) project. AMASE is a planned project that will pair 100 identical multi-fiber spectrographs with a large array of telephoto lenses to achieve a large area integral field spectroscopy survey of the sky at the spatial resolution of half an arcminute and a spectral resolution of R=15,000, covering important emission lines in the optical for studying the ionized gas in the Milky Way and beyond. The project will be enabled by a significant reduction in the cost of each spectrograph unit, which is achieved by reducing the beam width and the use of small-pixel CMOS detectors, 50um-core optical fibers, and commercial photographic lenses in the spectrograph. Although constrained by the challenging high spectral resolution requirement, we realize a 40% reduction in cost per fiber at constant etendue relative to, e.g., DESI. As the reduction of cost is much more significant than the reduction in the amount of light received per fiber, replicating such a system many times is more cost effective than building a single large spectrograph that achieves the same survey speed. We present the design of the prototype telescope and instrument system and the study of its cost effectiveness.

description: Mesh reconstruction from a 3D point cloud is an important topic in the fields of computer graphic, computer vision, and multimedia analysis. In this paper, we propose a voxel structure-based mesh reconstruction framework. It provides the intrinsic metric to improve the accuracy of local region detection. Based on the detected local regions, an initial reconstructed mesh can be obtained. With the mesh optimization in our framework, the initial reconstructed mesh is optimized into an isotropic one with the important geometric features such as external and internal edges. The experimental results indicate that our framework shows great advantages over peer ones in terms of mesh quality, geometric feature keeping, and processing speed.

description: We report the detection and analysis of a radio flare observed on 17 April 2014 from Sgr A* at $9$ GHz using the VLA in its A-array configuration. This is the first reported simultaneous radio observation of Sgr A* across $16$ frequency windows between $8$ and $10$ GHz. We cross correlate the lowest and highest spectral windows centered at $8.0$ and $9.9$ GHz, respectively, and find the $8.0$ GHz light curve lagging $18.37^{+2.17}_{-2.18}$ minutes behind the $9.9$ GHz light curve. This is the first time lag found in Sgr A*'s light curve across a narrow radio frequency bandwidth. We separate the quiescent and flaring components of Sgr A* via flux offsets at each spectral window. The emission is consistent with an adiabatically-expanding synchrotron plasma, which we fit to the light curves to characterize the two components. The flaring emission has an equipartition magnetic field strength of $2.2$ Gauss, size of $14$ Schwarzschild radii, average speed of $12000$ km s$^{-1}$, and electron energy spectrum index ($N(E)\propto E^{-p}$), $p = 0.18$. The peak flare flux at $10$ GHz is approximately $25$% of the quiescent emission. This flare is abnormal as the inferred magnetic field strength and size are typically about $10$ Gauss and few Schwarzschild radii. The properties of this flare are consistent with a transient warm spot in the accretion flow at a distance of $10$-$100$ Schwarzschild radii from Sgr A*. Our analysis allows for independent characterization of the variable and quiescent components, which is significant for studying temporal variations in these components.

description: The energy that knows the fastest growth is certainly PV systems with multiple opportunities for integration
(existing and new buildings) and wide farm.
Controlling this energy, the quality of its output, its productivity is of course fundamental. Therefore, for PV as with any
energy, monitoring of production, including predictive tools, will become widespread. Regulatory constraints related to
balancing power system will also make it almost mandatory.
In this context, the MONISOL project aims to propose an innovative monitoring of PV systems. This monitoring tool should
be used as a starting point for the development of skills for more comprehensive monitoring of new energy sources, smart
grid, intelligent buildings and electric vehicles. So the first step of a wide project.

description: The dome-shaped Fresnel-Köhler concentrator is a novel optical design for photovoltaic applications. It is based on two previous successful CPV optical designs: the FK concentrator with a flat Fresnel lens and the domeshaped Fresnel lens system developed by Daido Steel, resulting on a superior concentrator. This optical concentrator will be able to achieve large concentration factors, high tolerance (i.e. acceptance angle) and high optical efficiency,
three key issues when dealing with photovoltaic applications. Besides, its irradiance is distributed on the cell surface in a very even way. The concentrator has shown outstanding simulation results, achieving an effective concentrationacceptance product (CAP) value of 0.72, on-axis optical efficiency over 85% and good irradiance uniformity on the cell provided by Köhler integration. Furthermore, due to its high tolerance, we will present the dome-shaped Fresnel-Köhler concentrator as a cost-effective CPV optical design. All this makes this concentrator superior to other
conventional competitors in the current market.

description: The effect of disorder in the energetic heights and in the physical locations of fence barriers encountered by transmembrane molecules such as proteins and lipids in their motion in cell membranes is studied theoretically. The investigation takes as its starting point a recent analysis of a periodic system with constant distances between barriers and constant values of barrier heights, and employs effective medium theory to treat the disorder. The calculations make possible, in principle, the extraction of confinement parameters such as mean compartment sizes and mean intercompartmental transition rates from experimentally reported published observations. The analysis should be helpful both as an unusual application of effective medium theory and as an investigation of observed molecular movements in cell membranes.

description: Nuclear spin-dependent parity violation arises from weak interactions between electrons and nucleons, and from nuclear anapole moments. We outline a method to measure such effects, using a Stark-interference technique to determine the mixing between opposite-parity rotational/hyperfine levels of ground-state molecules. The technique is applicable to nuclei over a wide range of atomic number, in diatomic species that are theoretically tractable for interpretation. This should provide data on anapole moments of many nuclei, and on previously unmeasured neutral weak couplings.

2,6-diyl]] (PCPDTBT) and [6,6]-phenyl C71 butyric acid methyl ester (PC70BM) bulk-heterojunction organic solar
cells. These Ag NSs provide surface plasmons, which could enhance the electric field in the photoactive layer whilst
also improving the light scattering. By incorporating plasmon-active Ag NSs, enhanced optical absorption and
external quantum efficiency (EQE) were observed. In this work, Ag NSs of varying sizes were investigated, with the
aim of optimizing the performance of devices. The optical absorption of PCPDTBT:PC70BM blend films increases
from 550 nm as a result of plasmonic resonance of Ag NSs. The short-circuit current density (Jsc) increases by a
maximum ~9% for the 40 nm Ag NSs. These improvements are due to the light scattering of Ag NSs and the electric
field generated by the excited surface plasmons.

description: PURPOSE: In adults and children, transsphenoidal surgery (TSS) represents the cornerstone of management for most large or functioning sellar lesions with the exception of prolactinomas. Endocrine evaluation and management are an essential part of perioperative care. However, the details of endocrine assessment and care are not universally agreed upon. METHODS: To build consensus on the endocrine evaluation and management of adults undergoing TSS, a Delphi process was used. Thirty-five statements were developed by the Pituitary Society's Education Committee. Fifty-five pituitary endocrinologists, all members of the Pituitary Society, were invited to participate in two Delphi rounds and rate their extent of agreement with statements pertaining to perioperative endocrine evaluation and management, using a Likert-type scale. Anonymized data on the proportion of panelists' agreeing with each item were summarized. A list of items that achieved consensus, based on predefined criteria, was tabulated. RESULTS: Strong consensus (≥ 80% of panelists rating their agreement as 6-7 on a scale from 1 to 7) was achieved for 68.6% (24/35) items. If less strict agreement criteria were applied (ratings 5-7 on the Likert-type scale), consensus was achieved for 88% (31/35) items. CONCLUSIONS: We achieved consensus on a large majority of items pertaining to perioperative endocrine evaluation and management using a Delphi process. This provides an international real-world clinical perspective from an expert group and facilitates a framework for future guideline development. Some of the items for which consensus was not reached, including the assessment of immediate postoperative remission in acromegaly or Cushing's disease, represent areas where further research is needed.

description: This paper presents the electricity production comparison of grid connected photovoltaic systems to the
electrical power system of Greece. The geographical position of Greece provides very good conditions for the
exploitation of solar radiation throughout the year. Throughout the country there is a considerable spread both of the
available annual solar radiation (the annual global horizontal radiation ranges from 1.4 to 1.8 MWh/m2) and the
ambient temperature. Nevertheless, the annual electricity production does not have such a high fluctuation due to the
fact that PV systems in lower solar potential areas operate at lower temperatures compared to higher solar potential
areas. Therefore, for fixed PV systems using crystalline silicon modules, the energy production range documented
from various areas in Greece varies around 1560 kWh/kWp ± 140 kWh/kWp. The survey includes PV systems of all
module technologies as well as fixed orientation, 1 and 2 axis tracking systems.

In this review, the piezo-driven inkjet is discussed in detail since it is a mature technology and suitable for the production printing of printed electronics. In addition, other printing methods are considered for using higher viscosity ink and for producing smaller printed feature size. Various direct printing methods are compared in terms of jet mechanism, printing algorithm, and their applications. In particular high resolution printing methods using high viscosity inks, such as electrohydrodynamic jet, aerosol jet and micro-plotter are reviewed. To understand the recent status of industrial printing applications, display (liquid crystal display and organic light emitting diode) materials and printing issues are discussed. Finally, a brief overview of nano-particle metal based conductive inks is included because these inks have been widely used for printed electronics applications.

description: A widely held assumption on network dynamics is that similar components are more likely to exhibit similar behavior than dissimilar ones and that generic differences among them are necessarily detrimental to synchronization. Here, we show that this assumption does not generally hold in oscillator networks when communication delays are present. We demonstrate, in particular, that random parameter heterogeneity among oscillators can consistently rescue the system from losing synchrony. This finding is supported by electrochemical-oscillator experiments performed on a multi-electrode array network. Remarkably, at intermediate levels of heterogeneity, random mismatches are more effective in promoting synchronization than parameter assignments specifically designed to facilitate identical synchronization. Our results suggest that, rather than being eliminated or ignored, intrinsic disorder in technological and biological systems can be harnessed to help maintain coherence required for function.

description: A Bose-Einstein condensate produced by a Hamiltonian which is rotationally or translationally symmetric is fragmented as a direct result of these symmetries. A corresponding mean-field unfragmented state, with an identical energy to leading order in the number of particles, can generally be constructed. As a consequence, vanishingly weak symmetry-breaking perturbations destabilize the fragmented state, which would thus be extremely difficult to realize experimentally, and lead to an unfragmented condensate.

description: Full understanding of synchronous behavior in coupled dynamical systems beyond the identical case requires an explicit construction of the generalized synchronization manifold, whether we wish to compare the systems, or to understand their stability. Nonetheless, while synchronization has become an extremely popular topic, the bulk of the research in this area has been focused on the identical case, specifically because its invariant manifold is simply the identity function, and there have yet to be any generally workable methods to compute the generalized synchronization manifolds for non-identical systems. Here, we derive time dependent PDEs whose stationary solution mirrors exactly the generalized synchronization manifold, respecting its stability. We introduce a novel method for dealing with subtle issues with boundary conditions in the numerical scheme to solve the PDE, and we develop first order expansions close to the identical case. We give several examples of increasing sophistication, including coupled non-identical Van der Pol oscillators. By using the manifold equation, we also discuss the design of coupling to achieve desired synchronization.
A Kinetic Model of Friction in Strongly Coupled Strongly Magnetized Plasmas

description: Plasmas that are strongly magnetized in the sense that the gyrofrequency exceeds the plasma frequency exhibit novel transport properties that are not well understood. As a representative example, we compute the friction force acting on a massive test charge moving through a strongly coupled and strongly magnetized one-component plasma using a generalized Boltzmann kinetic theory. Recent works studying the weakly coupled regime have shown that strong magnetization leads to a transverse component of the friction force that is perpendicular to both the Lorentz force and velocity of the test charge; in addition to the stopping power component aligned antiparallel to the velocity. Recent molecular dynamics simulations have also shown that strong Coulomb coupling in addition to strong magnetization gives rise to a third component of the friction force in the direction of the Lorentz force. Here, we show that the generalized Boltzmann kinetic theory captures these effects, and generally agrees well with the molecular dynamics simulations over a broad range of Coulomb coupling and magnetization strength regimes. The theory is also used to show that a "gyro" component of the friction in the direction of the Lorentz force arises due to asymmetries associated with gyromotion during short-range collisions. Computing the average motion of the test charge through the background plasma, the transverse force is found to strongly influence the trajectory by changing the gyroradius and the gyro friction force is found to slightly change the gyrofrequency of the test charge resulting in a phase shift.

description: Determining the clumpiness of matter around galaxies is pivotal to a full understanding of the spatially inhomogeneous, multi-phase gas in the circumgalactic medium (CGM). We combine high spatially resolved 3D observations with hydrodynamical cosmological simulations to measure the cold circumgalactic gas clumpiness. We present new adaptive-optics-assisted VLT/MUSE observations of a quadruply lensed quasar, targeting the CGM of 2 foreground $z\sim$1 galaxies observed in absorption. We additionally use zoom-in FOGGIE simulations with exquisite resolution ($\sim$0.1 kpc scales) in the CGM of galaxies to compute the physical properties of cold gas traced by Mg\,II absorbers. By contrasting these mock-observables with the VLT/MUSE observations, we find a large spread of fractional variations of Mg\,II equivalent widths with physical separation, both in observations and simulations. The simulations indicate a dependence of the Mg\,II coherence length on the underlying gas morphology (filaments vs clumps). The $z_{\rm abs}$=1.168 Mg\,II system shows coherence over $\gtrsim$ 6 kpc and is associated with an [O\,II] emitting galaxy situated 89 kpc away, with SFR $\geq$ 4.6 $\pm$ {1.5} $\rm M_{\odot}$/yr and $M_{*}=10^{9.6\pm0.2} M_{\odot}$. Based on this combined analysis, we determine that the absorber is consistent with being an inflowing filament. The $z_{\rm abs}$=1.393 Mg\,II system traces dense CGM gas clumps varying in strength over $\lesssim$ 2 kpc physical scales. Our findings suggest that this absorber is likely related to an outflowing clump. Our joint approach combining 3D-spectroscopy observations of lensed systems and simulations with extreme resolution in the CGM put new constraints on the clumpiness of cold CGM gas, a key diagnostic of the baryon cycle.

description: The cost of chemical waste disposal is high. It is therefore important for the PV industry to find ways to
reduce chemical consumption and waste generation through chemical usage reduction, recovery, recycle, reuse,
and substitution. Iron, cobalt, nickel, titanium and copper are important metals that when present on a silicon
wafer surface adversely influence the efficiency of resulting PV devices. However, many of these surface ions can
be effectively removed during wafer cleaning by the addition of a complexing or chelating agent (such as SX-E™). In
this paper, we explore the process optimization as well as the removal of several of these metal ion complexes.

description: Hepatitis B virus (HBV) infection is endemic in some parts of Asia, Africa and South America and remains to be a significant public health problem in these areas. It is known as a leading risk factor for the development of hepatocellular carcinoma, but epidemiological studies have also shown that the infection may increase the incidence of several types B-cell lymphoma. Here, by characterizing altogether 275 Chinese diffuse large B-cell lymphoma (DLBCL) patients, we showed that patients with concomitant HBV infection (surface antigen positive, HBsAg+) are characterized by a younger age, a more advanced disease stage at diagnosis and a reduced overall survival. Furthermore, by whole genome/exome sequencing of 96 tumors and the respective peripheral blood samples and targeted-sequencing of 179 tumors from these patients, we observed an enhanced rate of mutagenesis and a distinct set of mutation targets in HBsAg+ DLBCL genomes, which could be partially explained by the activities of APOBEC and activation induced cytidine deaminase (AID). By transcriptome analysis, we further showed that the HBV-associated gene expression signature is contributed by the enrichment of genes regulated by BCL6, FOXO1 and ZFP36L1. Finally, by analysis of immunoglobulin heavy chain gene sequences, we showed that an antigen-independent mechanism, rather than a chronic antigenic simulation model, is favoured in HBV-related lymphomagenesis. Taken together, we present the first comprehensive genomic and transcriptomic study that suggests a link between HBV infection and B-cell malignancy. The targetable genetic alterations identified in this study may also provide opportunities for development of novel therapeutic strategies.
Studying wildfire spread using stationary burners

description: A method for performed experiments using stationary gas burners and liquid

fuel-soaked wicks to study flame geometry and buoyant instabilities important to

fundamental wildland fire behaviour has been developed. This thesis focuses on

experiments performed with stationary fires to carefully study instabilities observed

in spreading fires that suggest they play a critical role in fire spread.

Two types of flow conditions were used to perform experiments similar to

wildfire spread conditions: sloped fuel surface and forced-flow (wind aided). Small-

scale inclined experiments for performed at the University of Maryland with liquid-

fuel soaked wicks and large-scale experiments at the USDA Forest Service Missoula

Fire Sciences Laboratory with a gas-burner. These experiments were performed with

over a range of heat-release-rates and burner sizes for angles from 0 to 60 degrees

from the horizontal. Forced-flow experiments were performed in a large-scale wind

tunnel at the Missoula Fire Laboratory and at the University of Maryland with a

well characterized wind blower with gas-burners. These experiments were performed

for a range of heat-release-rates and burner sizes in wind speeds from 0.2 to 3.0 ms−1

The flame geometry was determined using high-speed videography. Important

two-dimensional flame geometry parameters such as centerline flame length and

flame tilt angle were measured from these images.

Flame intermittency and pulsation close to the surface was measured using

high-speed videography and micro-thermocouples. A method was developed to

track the extension of the flame close to the surface which would come in direct

contact with unburnt fuels ahead of the fire. These methods showed that the pul-

sation frequency is complicated suggesting large scale structures in the flow. Using

these frequency the stationary experiments follow similar Strouhal-Froude scaling

for flame pulsations in spreading fires.

Stream-wise streaks in the flow were observed and measured using high-speed

videography. Streak spacing has been observed to be associated with possible

Gotler votice structures in the fire. The spacing for streaks at the base of the

flame for these startionary experiments appear to be dependent on the boundary-

layer conditions and could possibly scale with the centerline flame length similar to

flame towers observed in spreading fires.
Scaling Analysis of the Site-Diluted Ising Model in Two Dimensions

description: A combination of recent numerical and theoretical advances are applied to analyze the scaling behaviour of the site-diluted Ising model in two dimensions, paying special attention to the implications for multiplicative logarithmic corrections. The analysis focuses primarily on the odd sector of the model (i.e., that associated with magnetic exponents), and in particular on its Lee-Yang zeros, which are determined to high accuracy. Scaling relations are used to connect to the even (thermal) sector, and a first analysis of the density of zeros yields information on the specific heat and its corrections. The analysis is fully supportive of the strong scaling hypothesis and of the scaling relations for logarithmic corrections.

description: In the crystalline PV module, the integrity of EVA to cell metallization adhesion is imperative for long
term reliability. In traditional module layups the c-Si wafers are encapsulated in EVA polymer for environmental
protection, optical coupling, shock absorption, and dielectric properties. In addition to glass and back sheet adhesion,
the adhesion of the EVA to BSF aluminum and front contact silver metallizations must be robust. With the
introduction of very low bow BSF formulations, the BSF to wafer adhesion may be compromised. Further
complicating this reliability issue is the lack of an industry standard to test BSF-wafer adhesion. This paper describes
and discusses several methods for testing the adhesion of these interfaces using EVA as the adhesive. Measurements
of the EVA to BSF adhesion, which can be significantly reduced by excessive micro-pilling or surface dusting, are
discussed. This paper will detail the test setups for both nail head type tensile testing and peel strength testing using
FPE backsheet for BSF adhesion. Steam aging effects are also explored and reported. Lastly adhesion-bow tradeoffs
are discused and best-of-class bow data presented.

description: Anomalous Hall effect and spin Hall effect originate due to spin-orbit coupling that in the Kohn-Luttinger ${\bf k}\cdot{\bf p}$ formalism is represented by anomalous terms in the coordinate and velocity operators. Relation of these operators to the Berry curvature in the momentum space is presented for electrons in GaAs type semiconductors. For centrosymmetric semiconductors, transformational properties of Berry curvature are discussed.

description: Telecommunication service providers have to guarantee acceptable speech quality during a phone call to avoid a negative impact on the users' quality of experience. Currently, there are different speech quality assessment methods. ITU-T Recommendation G.107 describes the E-model algorithm, which is a computational model developed for network planning purposes focused on narrowband (NB) networks. Later, ITU-T Recommendations G.107.1 and G.107.2 were developed for wideband (WB) and fullband (FB) networks. These algorithms use different impairment factors, each one related to different speech communication steps. However, the NB, WB, and FB E-model algorithms do not consider wireless techniques used in these networks, such as Multiple-Input-Multiple-Output (MIMO) systems, which are used to improve the communication system robustness in the presence of different types of wireless channel degradation. In this context, the main objective of this study is to propose a general methodology to incorporate wireless network parameters into the NB and WB E-model algorithms. To accomplish this goal, MIMO and wireless channel parameters are incorporated into the E-model algorithms, specifically into the $I_{e,eff}$ and $I_{e,eff,WB}$ impairment factors. For performance validation, subjective tests were carried out, and the proposed methodology reached a Pearson correlation coefficient (PCC) and a root mean square error (RMSE) of $0.9732$ and $0.2351$, respectively. It is noteworthy that our proposed methodology does not affect the rest of the E-model input parameters, and it intends to be useful for wireless network planning in speech communication services.

description: We study whether the broad enhancement X(1576) arises from the final state interaction (FSI) of $ρ(1450,1700)\to ρ^+ρ^-\to K^{+}K^{-}$ decays. We consider both the absorptive and dispersive contribution of the above amplitudes since the intermediate states are very close to $ρ(1450,1700)$. The same mechanism leads to a similar enhancement around 1580 MeV in the $π^{+}π^-$ spectrum in the $J/ψ\to π^{0}π^{+}π^{-}$ channel, which can be used to test whether X(1576) can be ascribed to the FSI effect of $ρ(1450,1700)\to ρ^+ρ^-$.
