description: We introduce a new product formula which combines an orthogonal projection with a complex function of a non-negative operator. Under certain assumptions on the complex function the strong convergence of the product formula is shown. Under more restrictive assumptions even operator-norm convergence is verified. The mentioned formula can be used to describe Zeno dynamics in the situation when the usual non-decay measurement is replaced by a particular generalized observables in the sense of Davies.

description: We analyze how an action of a qubit channel (map) can be estimated from the measured data that are incomplete or even inconsistent. That is, we consider situations when measurement statistics is insufficient to determine consistent probability distributions. As a consequence either the estimation (reconstruction) of the channel completely fails or it results in an unphysical channel (i.e., the corresponding map is not completely positive). We present a regularization procedure that allows us to derive physically reasonable estimates (approximations) of quantum channels. We illustrate our procedure on specific examples and we show that the procedure can be also used for a derivation of optimal approximations of operations that are forbidden by the laws of quantum mechanics (e.g., the universal NOT gate).

description: Energy is a critical input in production and the main sources of energy in modern economies are exhaustible. Therefore sustaining aggregate consumption across generations requires reduction of the quantity of energy used per unit of output. Energy policies incentivize the deployment of new technologies that will not only increase energy efficiency but also impact the ease with which capital and materials can substitute for energy and hence the ability of societies to sustain consumption. Therefore an assessment of the impact of energy policies on sustainable consumption requires accounting for the link between technological progress and substitutability. We first allow for biased technical change and find that capital augmenting technical change (e.g. diffusion of biofuels and other bioenergy technologies) enhances sustainability. In addition, provided a sustainable consumption exists, Hicks-neutral technical change and capital accumulation increase maximum sustainable consumption. Energy augmenting technical change (e.g. modern nuclear technologies) reduces maximum sustainable consumption. Second we allow for both biased technical change and variable elasticity of substitution. Results show that an elasticity of substitution between capital and energy greater than one is a necessary condition for existence of a positive sustainable consumption. Moreover, provided a sustainable consumption exists, technical change increases maximum sustainable consumption regardless of its bias. Energy augmenting technical change enhances sustainability through its positive effect on capital energy substitutability.
title: The problem of Beckett in postmodern American literature
Creators: name: Baxter, James
Publisher: name: University of Reading
Year: 2018

description: In this thesis, I return to the unsettled ground of Beckett’s influence over the emergence of postmodern fiction. Taking on board Peter Boxall’s piercing assertion that ‘one of the most significant of Beckett’s legacies […] is a conception of legacy itself,’ (2009) I provide a narrative of inheritance in which the exhaustion of literary experiment glimpsed in Beckett provides a bequest that is simultaneously energising and enervating. In particular, I connect this to the strained relationship of Beckett regarding the U.S., enshrined in his statement that this is ‘somehow not the right country for me.’ (Knowlson, 1996) The first chapter details the practicalities of Beckett’s U.S. migration via the Grove Press periodical Evergreen Review. Beckett’s 16 (1957-1973) appearances in the American periodical serve as a core vehicle of the author’s deracination, contextualising his publisher Barney Rosset’s description of Beckett’s ‘nontogetherness.’ The second chapter focuses on the work of Thomas Pynchon, in which Beckett’s poetics of exhaustion is integrated alongside the vitalism of the popular Beat avant-garde staged in Evergreen. In particular, I argue that Beckett’s influence intersects with the postmodern problem of hermeneutics, dramatized through shared images of ending, ‘Zero,’ and entropy. The final chapter reframes the Beckettian disjuncture against the work of Don DeLillo and the author’s interrogation of ‘this whole global, yet American, postmodern culture.’ (Jameson, 1991) Framed by DeLillo as the ‘last writer to shape the way we think and see,’ (Mao II, 157) Beckett’s presence is one of termination; at the same time, it discloses a means whereby fiction might ‘extend into the world.’ (Adelman, 2004) Alongside developments in DeLillo’s spatial-poetics to a fiction set ‘nowhere in particular,’ I finally provide a view of Beckett’s problematic bequest as one that is integrated into the fabric of the text over time.

description: This paper aims to explore the socio-economic profiles of the nutrition label users and focuses on seven key nutrients: calories, calories from fat, total fat, trans fat, saturated fat, cholesterol, and sodium. The data are from National Health and Nutrition Examination Survey (NHANES) 2005-2006 and Continuing Survey of Food Intakes by Individuals (CSFII) 1994-96. Similar conclusions are drawn from both data sets: those consumers who are older, better educated, higher income, female, and have higher nutrition knowledge will have higher probability to use nutrition labels; those consumers who are in larger size families and being either Hispanic or black have lower probability of using nutrition labels.

description: (Abridged abstract) We present an analysis of the X-ray emission of the rapidly rotating giant star YY Mensae observed by Chandra HETGS and XMM-Newton. Although no obvious flare was detected, the X-ray luminosity changed by a factor of two between the XMM-Newton and Chandra observations taken 4 months apart. The coronal abundances and the emission measure distribution have been derived from three different methods using optically thin collisional ionization equilibrium models. The abundances show an inverse first ionization potential (FIP) effect. We further find a high N abundance which we interpret as a signature of material processed in the CNO cycle. The corona is dominated by a very high temperature (20-40 MK) plasma, which places YY Men among the magnetically active stars with the hottest coronae. Lower temperature plasma also coexists, albeit with much lower emission measure. Line broadening is reported, which we interpret as Doppler thermal broadening, although rotational broadening due to X-ray emitting material high above the surface could be present as well. We use two different formalisms to discuss the shape of the emission measure distribution. The first one infers the properties of coronal loops, whereas the second formalism uses flares as a statistical ensemble. We find that most of the loops in the corona of YY Men have their maximum temperature equal to or slightly larger than about 30 MK. We also find that small flares could contribute significantly to the coronal heating in YY Men. Although there is no evidence of flare variability in the X-ray light curves, we argue that YY Men's distance and X-ray brightness does not allow us to detect flares with peak luminosities Lx <= 10^{31} erg/s with current detectors.

Losses of honey bee colonies and risk factors for their mortality in Bulgaria during 2020
Creators: name: Iliyana I. Ilieva, Evgeniya N. Ivanova
Publisher: name: Zenodo
Year: 2021
Subjects: honey bee, Apis mellifera, reasons for mortality, forage sources, pesticides

description: The study is based on a comparative analysis of the established losses of bee colonies by regions in Bulgaria and on the characterization of the risk factors for available mortality in 2020. Information for different types of forage sources with potential risk for Apis mellifera due to pesticide treatment, was presented and analyzed. By using the international standardized COLOSS questionnaire for 2020, members of the National Bee Breeding Association and independent beekeepers, owners of a total of 64 apiaries (over 6,800 bee colonies), located in all regions in Bulgaria, were surveyed. Beekeepers were asked to answer questions about the number of wintering honey bee colonies and how many of them after the winter: were alive but had unsolvable queen problems; were lost through natural disaster and were dead or reduced to a few hundred bees. The survey data show that the highest mortality was found for the North Central region (19%), and the lowest – for the Northwest (1%) and Southwest (2%) regions. Among the reasons for the loss of bee colonies, the leading one is the mortality of honey bees or their significant reduction in the colonies, which is also related to the negative impact of the applied pesticides in the studied areas. In this aspect, the most serious problems were reported in the North Central and Southeast (7%) regions. The presented and analyzed data should be taken into account when developing activities to protect the honey bee health status in Bulgaria.

The collection includes demobilisation documentation. UPDATE (Feb 19 2019): We received an email from R Bagshaw, who kindly pointed out the following: From the evidence offered it does not appear that Pte William Haxby was wounded and entitled to 'Wounded Stripes Blue' x 2. His Certificate of Transfer to Reserve on Demobilisation indicates: Medals authorised prior to 11.11.18 - Nil
Wound Stripes - Nil
 Chevrons Red - Nil
Chevrons Blue - Two (these are for Overseas Service [starting after 1 January 1915]. Two such chevrons indicate at least one year and 1 day [366+ days], but less than two years and 1 day [which would have qualified for a 3rd chevron], overseas service starting from day one in theatre and the relevant completed time/date thereafter - not wounds.)
Note: - Red chevron for first year, if starting in 1914, first day overseas to 1 year thereafter. - If still serving overseas at 1 year and 1 day a second, blue chevron. - Further 1 year later, another blue chevron, and so on. So, if serving overseas August 1914 to a later date in August 1919 inclusive, a soldier would theoretically accumulate 1 x red and 5 x blue chevrons. If starting in 1915 or later, then just blue chevrons would be awarded.
The geometry of form : a preference study
Creators: name: Kennedy, Carolyn Joan
Publisher: name: University of British Columbia
Year: 2009

description: This study attempts to determine whether the general public prefer curved edges over angular edges in urban park settings. Additionally, the construct validity of the information processing theory is called into doubt because of the difficulty in drawing sound conclusions when using compound constructs. It is posited that some of the results from the information processing experiments may be explained using simple concepts such as preference for curvilinear form. An experiment was conducted using four sets of images- two water features, one path and one combined planter and path which were manipulated into twenty different images that vary in degrees of angularity to curvilinearity. One group of images contained the entire scene (contextual condition) while the other set had most of the background blocked from the scene (non-contextual condition). Eighty participants from the Vancouver Aquatic Centre completed a balanced paired comparison task with 40 image comparison slides. Findings include strong correlations between curvilinearity and number of wins in seven of the eight image sets. The results of one water image set differed between the contextual and non-contextual groups. The primary conclusion is that the general public prefers landscape objects that have curved edges over those with angular edges. Additionally, the results provide grounds to question previous findings which claim that preference of s-curved paths are due to mystery because of a promise of new information. The third purpose of this study was the exploration of developing theories derived from quantitative research that are applicable to the practice of landscape architecture. A design application at Kitsilano Beach is explored to investigate the utility of the current study. It is concluded that it is possible to use quantitative research to develop practical design theories and future research using varied methodologies is suggested.

description: In this study we use data envelopment analysis to decompose the overall economic efficiency of a sample of ethanol plants into three subcomponents: technical efficiency, allocative efficiency and a new component we call marketing efficiency. The relative importance of these sources of efficiency is of particular interest given the recent history of bankruptcies, plant closings and ownership change in the industry. Results reveal that observed production units are very efficient from a technical point of view as suggested by a standard deviation of 1% in technical efficiency. However, our results also show that bigger plants tend to be more economically efficient than others. The conventional methodology would have identified this difference as coming from allocative sources, i.e. bigger plants were correct in anticipating better relative prices and built more capacity accordingly. However introduction of a new concept we call marketing efficiency reveals that bigger production units obtain better relative prices (through marketing contracts) than smaller production units rather than anticipating prices more accurately. This might be a potential reason underlying the recent wave of mergers and acquisitions in the industry.
Parametric derivation of the observable relativistic periastron advance for binary pulsars

Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We compute the dimensionless relativistic periastron advance parameter $k$, which is measurable from the timing of relativistic binary pulsars. We employ for the computation the recently derived Keplerian-type parametric solution to the post-Newtonian (PN) accurate conservative dynamics of spinning compact binaries moving in eccentric orbits. The parametric solution and hence the parameter $k$ are applicable for the cases of \emph{simple precession}, namely, case (i), the binary consists of equal mass compact objects, having two arbitrary spins, and case (ii), the binary consists of compact objects of arbitrary mass, where only one of them is spinning with an arbitrary spin. Our expression, for the cases considered, is in agreement with a more general formula for the 2PN accurate $k$, relevant for the relativistic double pulsar PSR J0737--3039, derived by Damour and Schäfer many years ago, using a different procedure.

description: The cargo operation planning, the process of implementation is one of the most difficult tasks carried out on liquid cargo vessels. The chief officer’s task is to process a huge amount of information, accurately enter data into a special computer, consistently calculate the stages of the work, and finally the most important is to complete the task in the shortest period of time. In the implementation, less attention is paid to the economic use of cargo mechanisms, their wear, and fuel costs. Despite the recommendations and strategies for the effective management of cargo operations, modern artificial intelligence has not yet fully replaced the mankind. We offer a modern and effective way to solve problems, such as maritime universities and maritime training center simulator classes’ students will search the most effective ways of cargo operation. The collaboration among vessel, university and terminal would be distance in the internet cloud, which provides: the ships’ crew work schedule reduction, a wide choice of cargo operations plans, selection of the optimal option, energy-saving, only target use of mechanisms, which finally lead to less wear and tear, fuel economy and, consequently reduction of CO2 pollution in the atmosphere. It will also reduce cargo operation time, thus reducing port and terminal fees. More over this principle of operation will increase the number of qualified personnel in the future and will be used in the future for remote control liquid cargo operations on unmanned vessels of future.

description: We present a new spectroscopic study of the faint Milky Way satellite Sagittarius II. Using multi-object spectroscopy from the Fibre Large Array Multi Element Spectrograph, we supplement the dataset of Longeard et al. (2020) with 47 newly observed stars, 19 of which are identified as members of the satellite. These additional member stars are used to put tighter constraints on the dynamics and the metallicity properties of the system. We find a low velocity dispersion of SgrII v = 1.7 +/- 0.5 km s-1, in agreement with the dispersion of Milky Way globular clusters of similar luminosity. We confirm the very metal-poor nature of the satellite ([Fe/H]_SgrII = -2.23 +/- 0.07) and find that the metallicity dispersion of Sgr II is not resolved, reaching only 0.20 at the 95% confidence limit. No star with a metallicity below -2.5 is confidently detected. Therefore, despite the unusually large size of the system (rh = 35.5 +1.4-1.2 pc), we conclude that Sgr II is an old and metal-poor globular cluster of the Milky Way.

Entropic Optimal Transport between Unbalanced Gaussian Measures has a Closed Form

description: Although optimal transport (OT) problems admit closed form solutions in a very few notable cases, e.g. in 1D or between Gaussians, these closed forms have proved extremely fecund for practitioners to define tools inspired from the OT geometry. On the other hand, the numerical resolution of OT problems using entropic regularization has given rise to many applications, but because there are no known closed-form solutions for entropic regularized OT problems, these approaches are mostly algorithmic, not informed by elegant closed forms. In this paper, we propose to fill the void at the intersection between these two schools of thought in OT by proving that the entropy-regularized optimal transport problem between two Gaussian measures admits a closed form. Contrary to the unregularized case, for which the explicit form is given by the Wasserstein-Bures distance, the closed form we obtain is differentiable everywhere, even for Gaussians with degenerate covariance matrices. We obtain this closed form solution by solving the fixed-point equation behind Sinkhorn's algorithm, the default method for computing entropic regularized OT. Remarkably, this approach extends to the generalized unbalanced case -- where Gaussian measures are scaled by positive constants. This extension leads to a closed form expression for unbalanced Gaussians as well, and highlights the mass transportation / destruction trade-off seen in unbalanced optimal transport. Moreover, in both settings, we show that the optimal transportation plans are (scaled) Gaussians and provide analytical formulas of their parameters. These formulas constitute the first non-trivial closed forms for entropy-regularized optimal transport, thus providing a ground truth for the analysis of entropic OT and Sinkhorn's algorithm.

description: The article is devoted to the issues of involvement of teachers and maritime professionals in maritime education. In particular, authors discuss professional training for basic subject teachers in order to become experts in teaching e.g. Ships Stability, MARPOL, and Environmental Pollution etc. The higher education institutions have specific qualification requirements for their academic staff members. This also applies to maritime lecturers who in addition need an appropriate sea experience as well as sufficient knowledge of related subject(s). Maritime professionals need to pass special trainings on order to get permission to deliver lectures in Maritime Academy. The authors make an attempt to analyze the possibility of passing professional training for those who are not involved in Maritime field and get special expertise to become specialist of profile subjects.

description: In this paper, the new empirical industrial organization approach with a dynamic model is simultaneously employed to measure the degree of oligopoly, oligopsony power, and cost efficiency in the U.S. beef packing industry. The oligopsony power is estimated with two effects: cash cattle procurement market power and captive supply market power. The model is estimated by the Generalized Method of Moments using monthly data from 1990 to 2006. The empirical results reveal the presence of market power in both the beef retail market and the cattle procurement market in the sample period. The captive supply is a source of oligopsony market power, but the effect is considerably small. The oligopsony market power is greater and less stable than oligopoly market power for the whole sample period. The cost efficiency effect outweighs the market power effects for the sample period.
Effect of the anomalous magnetic moment of quarks on magnetized QCD matter and meson spectra

description: We systematically investigate the effect of the anomalous magnetic moment(AMM) of quarks on the magnetized QCD matter, including the magnetic susceptibility, the inverse magnetic catalysis around the critical temperature and the neutral/charged pion and rho meson spectra under magnetic fields. The dynamical AMM of quarks, its coupling with magnetic field causes Zeeman splitting of the dispersion relation of quarks thus changes the magnetism properties and meson mass spectra under magnetic fields. It is found that including the AMM of quarks cannot fully understand lattice results of the magnetized matter: The AMM of quarks reduces the dynamical quark mass thus causes the inverse magnetic catalysis around $T_c$. The neutral pion mass is very sensitive to the AMM, it decreases with magnetic field quickly, and the charged pion mass shows a nonlinear behavior, i.e., firstly linearly increases with the magnetic field and then saturates at strong magnetic field. For rho meson, it is observed that AMM reduces the mass of neutral rho meson mass with different $s_z$, and reduces the mass of $s_z=+1,0$ component charged rho meson mass but enhances the $s_z=-1$ component charged rho meson mass. The magnetic susceptibility at low temperature can be either positive or negative with different AMM.

description: Magnetohydrodynamic (MHD) turbulence in the solar wind is observed to show the spectral behavior of classical Kolmogorov fluid turbulence over an inertial subrange and departures from this at short wavelengths, where energy should be dissipated. Here we present the first measurements of the electric field fluctuation spectrum over the inertial and dissipative wavenumber ranges in a $β\gtrsim 1$ plasma. The $k^{-5/3}$ inertial subrange is observed and agrees strikingly with the magnetic fluctuation spectrum; the wave phase speed in this regime is shown to be consistent with the Alfvén speed. At smaller wavelengths $k ρ_i \geq 1$ the electric spectrum is softer and is consistent with the expected dispersion relation of short-wavelength kinetic Alfvén waves. Kinetic Alfvén waves damp on the solar wind ions and electrons and may act to isotropize them. This effect may explain the fluid-like nature of the solar wind.

description: It is shown that the translation-invariant bipolaron theory of superconductivity can explain the dependence of the isotope coefficient in high-temperature superconductors on the critical temperature of a superconducting transition: in the case of strong electron-phonon interaction, the isotope coefficient is low when doping is optimal and high when it is weak. It is demonstrated that in the case of London penetration depth, the absolute value of the isotope coefficient behaves in the opposite way. A conclusion of the great role of non-adiabaticity in the case of weak doping is made. The criteria for d-wave phonon input into the isotope effect is established.

description: Abundances of C and N are derived from features due to the CH G-band and to the UV CN band measured on high resolution (R ~ 40,000) UVES spectra of more than 40 dwarfs and subgiants in NGC 6397, NGC 6752 and 47 Tuc. Oxygen abundances (or upper limits) are available for all stars in the sample. Isotopic ratios 12C/13C were derived from the CH molecular band. This is the first determination of this ratio in unevolved dwarf stars in globular clusters. By enlarging the sample of subgiants in NGC 6397 studied in Gratton et al. (2001), we uncovered, for the first time, large variations in both Na and O also in this cluster. The origin of the chemical inhomogeneities must be searched for outside the stars under scrutiny. Our data indicate that in unevolved or slightly evolved stars in these clusters C abundances are low but not zero, also in stars with large N-enhancements and O-depletions, and that the isotopic ratios 12C/13C are low, but never reach the equilibrium value of the CN-cycle. When coupled with the run of O and Na abundances, these findings possibly require that, in addition to CNO burning and p-captures, some triple-alpha process is also involved: previously evolved intermediate-mass AGB stars are then the most likely polluters.

description: Chlamydia trachomatis (Ct) is the most reported sexually transmitted infection in the United States with a major cause of infertility and pelvic inflammatory disease among women. Despite decades of screening women for Ct, rates increase among young African Americans (AA). We create and analyze an agent-based network model to understand the spread of Ct. We calibrate the model parameters to agree with survey data showing Ct prevalence of 12% of the women and 10% of the men in the 15-25 year-old AA in New Orleans, Louisiana. Our model accounts for long-term and casual partnerships. The network captures assortative mixing of individuals by preserving the joint-degree distributions observed in the data. We compare the efficiency of intervention strategies of randomly screening men, partner notification, which includes partner treatment, partner screening, and rescreening for infection. We compare the difference between treating partners of an infected person both with and without testing them. We observe that although increased Ct screening, rescreening and treating most of the partners of infected people will reduce the prevalence, these mitigations alone are not sufficient to control the epidemic. The current practice is to treat the partners of an infected individual, without first testing them for infection. The model predicts that if a sufficient number of the partners of all infected people are tested and treated, then there is a threshold condition where the epidemic can be mitigated. This threshold results from the expanded treatment network created by treating the partners of the infected partners of an individual. Although these conclusions can help design future Ct mitigation studies, we caution the reader that these conclusions are for the mathematical model, not the real world, and are contingent on the validity of the model assumptions.
Dynamics of localized spins coupled to the conduction electrons with charge/spin currents

description: The effects of the charge/spin currents of conduction electrons on the dynamics of the localized spins are studied in terms of the perturbation in the exchange coupling $J_{K}$ between them. The equations of motion for the localized spins are derived exactly up to $O(J_{K}^2)$, and the equations for the two-spin system is solved numerically. It is found that the dynamics depends sensitively upon the relative magnitude of the charge and spin currents, i.e., it shows steady state, periodic motion, and even chaotic behavior. Extension to the multi-spin system and its implications including possible ``spin current detector'' are also discussed.

Anomalous precursor diamagnetism at low reduced magnetic fields and the role of Tc inhomogeneities in the superconductors Pb55In45 and underdoped La1.9Sr0.1CuO4

description: The magnetic field dependence of the magnetization was measured above the superconducting transition in a high-Tc underdoped cuprate La1.9Sr0.1CuO4 and in a low-Tc alloy (Pb55In45). Near the superconducting transition [typically for (T-Tc)/Tc<0.05] and under low applied magnetic field amplitudes [typically for H/Hc2(0)<0.01, where Hc2(0) is the corresponding upper critical field extrapolated to T=0 K] the magnetization of both samples presents a diamagnetic contribution much larger than the one predicted by the Gaussian Ginzburg-Landau (GGL) approach for superconducting fluctuations. These anomalies have been already observed in cuprate compounds by various groups and attributed to intrinsic effects associated with the own nature of these high-Tc superconductors. However, we will see here that our results in both high and low-Tc superconductors may be explained quantitatively, and consistently with the GGL behavior observed at higher fields, by just taking into account the presence in the samples of an uniform distribution of Tc inhomogeneities. These Tc inhomogeneities, which may be in turn associated with stoichiometric inhomogeneities, were estimated from independent measurements of the temperature dependence of the field-cooled magnetic susceptibility under low applied magnetic fields.

description: We report results of an analysis of the attribution of relative responsibility across the stages of the food chain for ensuring food safety. Specifically, we identify perceptions of the share of the overall responsibility that each stage in the food chain has to ensure that the meat people cook and eat at home does not cause them to become ill. Results are reported for two groups of stakeholders: consumers and farmers, and for two types of meat: chicken and beef. The stakeholders’ opinions regarding the relative degrees of responsibility of the sequential food chain stages (feed supplier, farmer, livestock transportation, abattoir,… consumer) are elicited via surveys using the Maximum Difference technique (best-worst scaling). The data are analyzed using mixed logit models estimated via Bayesian techniques. We find that consumers and farmers both tend to allocate a relatively low share of responsibility to their own food safety role. So, consumers tend to think farmers are more responsible for ensuring meat safety than farmers do. Similarly, farmers tend to think consumers have a greater degree of responsibility than consumers themselves believe. Thus, there is a consistent pattern of downplaying the extent of one’s own responsibility. Further, consumers tend to allocate the highest shares of responsibility to the middle stages of the meat food chain. This contrasts with farmers who tend to allocate the highest shares of responsibility to the latter stages of the chain towards consumers, believing that the earlier stages of the chain (until the livestock arrive at the abattoir) have a relatively low share of responsibility. The analysis is currently being extended to a third group of food chain actors: abattoir workers.

description: For each of the 63 segments separately, we accumulated all 10,000 permutations across all 203 SNPs, therefore retaining 2,030,000 null results for each segment. We then performed a Kolmogorov-Smirnov test to statistically investigate whether the permutation p-values follow a uniform distribution [0,1]. This was done for the two meta-analysis tracks separately, for each segment, using each time the combined 2,030,000 results per segment. The QQ plots for each segment are in the QQ_PeaksCombined.zip folder and the p-values and test statistics for the KS test are in the KS_test.xlsx file.
