description: Vacancies in materials structure -- lowering its atomic density -- take the system closer to the atomic limit, to which all systems are topologically trivial. Here we show a mechanism of mediated interaction between vacancies inducing a topologically non-trivial phase. Within an {\it ab initio} approach we explore topological transition dependence with the vacancy density in transition metal dichalcogenides. As a case of study, we focus on the PtSe$_2$, to which pristine form is a trivial semiconductor with an energy gap of $1.2$\,eV. The vacancies states lead to a large topological gap of $180$\,meV within the pristine system gap. We derive an effective model describing this topological phase in other transition metal dichalcogenide systems. The mechanism driving the topological phase allows the construction of backscattering protected metallic channels embedded in a semiconducting host.

description: We consider the impact of thermal conduction in clusters of galaxies on the (unmagnetized) interface between a cold gaseous cloud and a hotter gas flowing over the cloud (the so-called cold front). We argue that near the stagnation point of the flow conduction creates a spatially extended layer of constant thickness $Δ$, where $Δ$ is of order $\sim\sqrt{kR/U}$, and $R$ is the curvature radius of the cloud, $U$ is the velocity of the flow at infinity, and $k$ is the conductivity of the gas. For typical parameters of the observed fronts, one finds $Δ\ll R$. The formation time of such a layer is $\sim R/U$. Once the layer is formed, its thickness only slowly varies with time and the quasi-steady layer may persist for many characteristic time scales. Based on these simple arguments one can use the observed width of the cold fronts in galaxy clusters to constrain the effective thermal conductivity of the intra-cluster medium.

description: We demonstrate that the addition of a single carbon impurity leads to significant changes in the thermodynamic properties of Ni clusters consisting of more than a hundred atoms. The magnitude of the change induced is dependent upon the parameters of the Ni-C interaction. Hence, thermodynamic properties of Ni clusters can be effectively tuned by the addition of an impurity of a particular type. We also show that the presence of a carbon impurity considerably changes the mobility and diffusion of atoms in the Ni cluster at temperatures close to its melting point. The calculated diffusion coefficients of the carbon impurity in the Ni cluster can be used for a reliable estimate of the growth rate of carbon nanotubes.

description: Very massive primordial stars ($140 M_{\odot} < M < 260 M_{\odot}$) are supposed to end their lives as pair-instability supernovae. Such an event can be traced by a typical chemical signature in low metallicity stars, but at the present time, this signature is lacking in the extremely metal-poor stars we are able to observe. Does it mean that those very massive objects did not form, contrarily to the primordial star formation scenarios? Could they avoid this tragical fate? We explore the effects of rotation, anisotropic mass loss and magnetic fields on the core size of a very massive Population III model, in order to check if its mass is sufficiently modified to prevent the pair instability. We obtain that a Population III model of $150 M_{\odot}$ with $\upsilon/\upsilon_{\rm crit}=0.56$ computed with the inclusion of wind anisotropy and Tayler-Spruit dynamo avoids the pair instability explosion.

description: On November 9th, 1947, the exhibition of artworks recovered in Germany was inaugurated at Villa Farnesina in Rome. On display were mainly paintings and sculptures from the collections of Neapolitan museums stolen by the Nazis but returned to Italy a few months earlier, thanks to Rodolfo Siviero and his collaborators. Hidden in the abbey of Montecassino to escape the bombings of Naples, these artworks were evacuated by German troops after the Italian armistice, just before the destruction of the abbey by the Allies. Most of the pieces were returned in a few months, but some were not: they were a gift for Hermann Göring. The Reichsmarschall was indeed a greedy collector and during the war his collection increased through art confiscations in occupied countries. Among the artworks stolen from Montecassino was Titian's Danaë, painted for Cardinal Alessandro Farnese in 1545 and part of Capodimonte collection. By mythological subject and historical events, this canvas became the emblem of the rescue.
title:  Implementation of Digital Twins for Small Water Systems
Creators: name: Gill, Aidan
Publisher: name: University of Kentucky Libraries
Year: 2023
Subjects: classificationCode: 2.1
subject: FOS: Civil engineering

description: The main objective of this thesis is to develop a working digital twin for a small water system in central Kentucky which will serve as a general format for other similar systems in the region wishing to implement digital twins for operator support. While the benefit of having a calibrated hydraulic and water quality model is widely understood, small distribution systems tend to not have the same financial and economic means to properly support these tools. Creation of a digital twin using this methodology provides a means for operators to predict pressure, flows, chlorine residuals, and total trihalomethane (TTHM) concentrations within their system with little to no cost and maintenance.

The application is developed using the MATLAB app development toolkit and is then linked with the EPANET hydraulic and water quality engine via the EPANET-MATLAB toolkit. The application provides simple user inputs such as initial tank levels, pump scheduling, demand scenarios, and mapping capabilities for results.

Reliability of the digital twin output is rooted in the extended period simulation (EPS) calibration steps which ensure the variation of demands both spatially and temporally accurately reflect conditions seen in the system. Both the Box-Complex (multi pressure zone systems) and the bisection method (two zone systems) were used in the processing of tank telemetry and meter data to create representative demand factors.

The creation of a useful digital twin is highly reliant on both the programming capability of the developer and familiarity with the many nuances of hydraulic and water quality calibration which are necessary foundations upon which accurate predictions of key parameters are accomplished. While outputs given in the MATLAB interface are simple, accurate, and robust against failure, there is much to be desired by way of interactive mapping. Python offers a broader range of available libraries capable of supporting mapping which will make inputting parameters and viewing results much simpler for operators. Additionally, the tools provided in this digital twin use historical data for hydraulic calibration (demand factors) and testing which are useful based solely on operator understanding of which demand scenarios in the past will most accurately reflect what they will see in the present. Extension of these historical patterns into forecasted demands using machine learning or time series analysis will greatly improve the usefulness of the model and overall operator experience.

description: We firstly derive the stellar population properties: age and metallicity for $\sim$ 43,000 low redshift galaxies in the seventh data release (DR7) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey, which have no spectroscopic observations in the Sloan Digital Sky Survey(SDSS). We employ a fitting procedure based on the small-scale features of galaxy spectra so as to avoid possible biases from the uncertain flux calibration of the LAMOST spectroscopy. We show that our algorithm can successfully recover the average age and metallicity of the stellar populations of galaxies down to signal-to-noise$\geq$5 through testing on both mock galaxies and real galaxies comprising LAMOST and their SDSS counterparts. We provide a catalogue of the age and metallicity for $\sim$ 43,000 LAMOST galaxies online. As a demonstration of the scientific application of this catalogue, we present the Holmberg effect on both age and metallicity of a sample of galaxies in galaxy pairs.

description: The Canadian Labour Force Survey (LFS) is a monthly survey produced by Statistics Canada. It produces a number of data products used by researchers across the country. The monthly public use microdata files (PUMFs) that are distributed through the Data Liberation Initiative (DLI) in coordination with the data services provided by university libraries require accuracy and consistency of metadata in DDI format for online access. This presentation discusses the process for marking up the LFS across the different series of data files (1976 to present) in both English and French and across different metadata authorship from various institutions over the years.
Revealing the competition between charge-density wave and superconductivity in CsV$_3$Sb$_5$ through uniaxial strain

description: In this paper we report the impact of uniaxial strain $\varepsilon$ applied along the crystalline $a$ axis on the newly discovered kagome superconductor CsV$_3$Sb$_5$. At ambient conditions, CsV$_3$Sb$_5$ shows a charge-density wave (CDW) transition at $T_{\rm CDW}=94.5$ K and superconducts below $T_C = 3.34$ K. In our study, when the uniaxial strain $\varepsilon$ is varied from $-0.90\%$ to $0.90\%$, $T_C$ monotonically increases by $\sim 33\%$ from 3.0 K to 4.0 K, giving rise to the empirical relation $T_C (\varepsilon)=3.4+0.56\varepsilon+0.12\varepsilon^2$. On the other hand, for $\varepsilon$ changing from $-0.76\%$ to $1.26\%$, $T_{\rm CDW}$ decreases monotonically by $\sim 10\%$ from 97.5 K to 87.5 K with $T_{\rm CDW}(\varepsilon)=94.5-4.72\varepsilon-0.60\varepsilon^2$. The opposite response of $T_C$ and $T_{\rm CDW}$ to the uniaxial strain suggests strong competition between these two orders. Comparison with hydrostatic pressure measurements indicate that it is the change in the $c$-axis that is responsible for these behaviors of the CDW and superconducting transitions, and that the explicit breaking of the sixfold rotational symmetry by strain has a negligible effect. Combined with our first-principles calculations and phenomenological analysis, we conclude that the enhancement in $T_C$ with decreasing $c$ is caused primarily by the suppression of $T_{\rm CDW}$, rather than strain-induced modifications in the bare superconducting parameters. We propose that the sensitivity of $T_{\rm CDW}$ with respect to the changes in the $c$-axis arises from the impact of the latter on the trilinear coupling between the $M_1^+$ and $L_2^-$ phonon modes associated with the CDW. Overall, our work reveals that the $c$-axis lattice parameter, which can be controlled by both pressure and uniaxial strain, is a powerful tuning knob for the phase diagram of CsV$_3$Sb$_5$.

Year: 2010

description: Evaluation of several methods of fixing chicken skin for scanning electron microscopy (SEM) indicated standard chemical fixation using glutaraldehyde and osmium tetroxide followed by chemical dehydration with 2,2-dimethoxypropane to be the method of choice. SEM revealed that chicken skin has a convoluted surface. Two types of chicken skin, distinguishable on the basis of chemical composition and appearance were observed. Type I has a filamentous surface with 55% moisture and 25% fat, whereas Type II skin has a globular appearance, 52% fat and 33% moisture. The fatty acid profiles of Types I and II skin are the same. Bacteria have greater affinity for Type II than Type I skin. Attachment studies indicated that Salmonella typhimurium quickly attach to the skin surface and cannot be removed easily by washing with water or with water containing a surfactant.

description: We analyse scaling laws that govern macromolecules of different topology: polymer chains, homogeneous and miktoarm star polymers in a good solvent possibly constrained by a porous medium. The latter is modelled by long-range-correlated disorder with a pair correlation function g(r) that decays with a power law g(r) r^{-a} at large distances r. We show that this type of disorder changes the universality class of the system. Within the frames of the field-theoretical renormalization group approach we obtain the corresponding new universal critical exponents for systems of homogeneous and star copolymers and discuss different consequences of the architecture dependent change of the scaling behaviour.

description: Reactions on the proton-rich nuclides drive the nucleosynthesis in Core-Collapse Supernovae (CCSNe) and in X-ray bursts (XRBs). CCSNe eject the nucleosynthesis products to the interstellar medium and hence are a potential inventory of p-nuclei, whereas in XRBs nucleosynthesis powers the light curves. In both astrophysical sites the Ni-Cu cycle, which features a competition between $^{59}$Cu(p,$α$)$^{56}$Ni and $^{59}$Cu(p,$γ$)$^{60}$Zn, could potentially halt the production of heavier elements. Here, we report the first direct measurement of $^{59}$Cu(p,$α$)$^{56}$Ni using a re-accelerated $^{59}$Cu beam and cryogenic solid hydrogen target. Our results show that the reaction proceeds predominantly to the ground state of $^{56}$Ni and the experimental rate has been found to be lower than Hauser-Feshbach-based statistical predictions. New results hint that the $νp$-process could operate at higher temperatures than previously inferred and therefore remains a viable site for synthesizing the heavier elements.

description: High-resolution longslit Halpha spectra of the shell of the old nova DQ Her have been obtained with the William Herschel Telescope using the ISIS spectrograph. An equatorial expansion velocity of 370+/-14 km/s is derived from the spectra which, in conjunction with a narrowband Halpha image of the remnant, allows a distance estimate of 525+/-28 pc. An equatorial ring which exhibits enhanced [NII] emission has also been detected and the inclination angle of the shell is found to be 86.8+/-0.2 degrees with respect to the line of sight. The spectra also reveal tails extending from the clumps in the shell, which have a radial velocity increasing along their length. This suggests the presence of a stellar wind, collimated in the polar direction, which ablates fragments of material from the clumps and accelerates them into its stream up to a terminal velocity of order 800-900 km/s.

IMPROVING NON-ONCOLOGY PROVIDER KNOWLEDGE OF UNIQUE IMMUNOTHERAPY ADVERSE EVENTS
Creators: name: Nguyen, Enza Esposito
Publisher: name: Zenodo
Year: 2019

description: Among oncology patients, immunotherapy is being used with increasing frequency both as a single agent and in combination with chemotherapy and radiation. Immunotherapy adverse events (AEs) have a unique presentation and are often overlooked or misdiagnosed especially by non-oncology providers. This doctoral project sought to improve non-oncology provider knowledge about management of adverse events from one specific class of immunotherapy, checkpoint inhibitors, and subsequent patient outcomes. Methods included the use of the Promoting Action on Research Implementation in Health Services (PARIHS) model in delivery of tailored microteaching sessions to nurses from several hospital units and to emergency physicians with knowledge assessments before and after. Medical records were reviewed to assess patient and clinical outcomes before and after education of these non-oncology providers. There was a significant uptake in knowledge by non-oncology providers regarding checkpoint inhibitor adverse events and their appropriate management. The medical record review revealed important nurse educational gaps that were addressed at the end of the project. However, due to unforeseen problems in the clinical informatics department and issues with the electronic health record, the record review for patient outcomes was not comprehensive.
Can We Trust Tests To Automate Dependency Updates? A Case Study of Java Projects

description: Developers are increasingly using services such as Dependabot to automate dependency updates. However, recent research has shown that developers perceive such services as unreliable, as they heavily rely on test coverage to detect conflicts in updates. To understand the prevalence of tests exercising dependencies, we calculate the test coverage of direct and indirect uses of dependencies in 521 well-tested Java projects. We find that tests only cover 58% of direct and 20% of transitive dependency calls. By creating 1,122,420 artificial updates with simple faults covering all dependency usages in 262 projects, we measure the effectiveness of test suites in detecting semantic faults in dependencies; we find that tests can only detect 47% of direct and 35% of indirect artificial faults on average. To increase reliability, we investigate the use of change impact analysis as a means of reducing false negatives; on average, our tool can uncover 74% of injected faults in direct dependencies and 64% for transitive dependencies, nearly two times more than test suites. We then apply our tool in 22 real-world dependency updates, where it identifies three semantically conflicting cases and five cases of unused dependencies. Our findings indicate that the combination of static and dynamic analysis should be a requirement for future dependency updating systems.

description: The poems in this thesis deal primarily with finding a safe and perhaps even joyful place in this precarious and saddening world. If they have a theoretical foundation, it is in my fervent and idealistic desire that they be read aloud by ordinary people with the recognition that poetry can be entertainment; ordinary people and the details of our lives are my subjects, and my language is rarely other than formalized ordinary language. In these aspects, then, my work seems to lean toward both realism and romanticism.

The art which most. profoundly affected my literary development, however, is that of William Shakespeare, John Donne, T.S. Eliot, Robert Frost and Joyce Carol Dates--their poetry and prose, and especially the rhythms and images they created, recur consistently, often wordlessly, in my mind at unanticipated and involuntary intervals. In the same way, the rhythms and images of my own poems arrive in my mind of their own volition. The craft which has gone into this collection--focusing, sharpening the images, and working the sounds and rhythms so that the poems move--has been in the hope that the poems will delight and perhaps even enlighten others as they have me.

description: We investigate the enhancement of spin polarization in a quantum wire in the presence of a constriction and a spin-orbit coupling segment. It is shown that the spin-filtering effect is significantly heightened in comparison with the configuration without the constriction. It is understood in the studies that the constriction structure plays a critical role in enhancing the spin filtering by means of confining the incident electrons to occupy one channel only while the outgoing electrons occupy two channels. The enhancement of spin-filtering has also been analyzed within the perturbation theory. Because the spin polarization arises mainly from the scattering between the constriction and the segment with spin-orbit coupling, the sub-band mixing induced by spin-orbit interaction in the scattering process and the interferences result in higher spin-filtering effect.

description: The surface-density profiles of dense filaments, in particular those traced by dust emission, appear to be well fit with Plummer profiles, i.e. Sigma(b)=Sigma_B+Sigma_O{1+[b/w_O]^2}^{[1-p]/2}. Here Sigma_B is the background surface-density; Sigma_B+Sigma_O is the surface-density on the filament spine; b is the impact parameter of the line-of-sight relative to the filament spine; w_O is the Plummer scale-length (which for fixed p is exactly proportional to the full-width at half-maximum, w_O=FWHM/2{2^{2/[p-1]}-1}^{1/2}); and p is the Plummer exponent (which reflects the slope of the surface-density profile away from the spine).} In order to improve signal-to-noise it is standard practice to average the observed surface-densities along a section of the filament, or even along its whole length, before fitting the profile. We show that, if filaments do indeed have intrinsic Plummer profiles with exponent p_INTRINSIC, but there is a range of w_O values along the length of the filament (and secondarily a range of Sigma_B values), the value of the Plummer exponent, p_FIT, estimated by fitting the averaged profile, may be significantly less than p_INTRINSIC. The decrease, Delta p = p_INTRINSIC - p_FIT, increases monotonically with increasing p_INTRINSIC; with increasing range of w_O values; and -- if, but only if, there is a finite range of w_O values -- with increasing range of Sigma_B values. For typical filament parameters the decrease is insignificant if p_INTRINSIC = 2 (0.05

The FAIR principles facilitate more transparent and reproducible research by providing Research Data Management guidelines to make research output Findable, Accessible, Interoperable and Reusable. Research Data Management can be time and cost-efficient, improve the quality of scientific practice and provide recognition for all research output, greatly benefiting the individual researcher as well as the research community as a whole. According to the FAIR principles your research output should be Findable (F) by having a persistent identifier as well as metadata (data providing information about your data). This metadata has to be Accessible (A) by both humans and machines. Increased Interoperability (I) is achieved through the use of community standards and vocabulary, as well as open formats. When your research output is sufficiently documented and is accompanied with a license it becomes Reusable (R) for others. This poster offers some practical solutions to manage your research data and make your research output more FAIR.

description: Even though refugees are a growing population, their experiences in higher educational contexts have been little explored. The purpose of this narrative inquiry study is to explore the experiences of three multilingual refugees navigating a U.S. community college. More specifically, the goal is to examine what they perceived as challenges and supports while they navigated this institution of higher education in pursuit of degrees. The data revealed the participants experienced challenges related to English language proficiency, particularly in academic contexts. In addition, the participants perceived interactions with classmates as a challenge for them to pursue their academic goals. Participants’ narrative accounts revealed the importance of interactions with instructors, which they identified as a support for navigating college. The findings suggest that higher education institutions should extend their language support to multilingual students, particularly refugees, through their entire college trajectory. Further, this study demonstrates the need for more robust support for multilingual refugees to feel safe to express their cultural values and beliefs. A starting place is promoting awareness that multilingualism is present on campus and framing it as an asset. This study also emphasizes the impact of relationships with instructors as an often-overlooked source of support that should be recognized and maximized as an important part of multilingual refugees’ experience in U.S. higher education.

description: This article focuses on the Danaë painting (1527) by Jan Gossaert van Mabuse (1478-1532) (Munich, Bayerische Staatsgemäldesammlungen), developing the meaning of “psycho-spatial space” (Raumlichkeit) in the painting. In Gossaert’s Danaë, the space concerned is a sophisticated articulation of outer and inner discourse: the hard, dry, external space, with its eclectic architecture, in contrast with the sweltering, moist, internal space of the figure’s naked body. I develop Gossaert’s complex phantasmata surrounding architecture, decoration, and the female body in three phases: first, the space that allows access to intimacies; second, the gendered space as (un)heimlichkeit and voyeurism, and, third, space as the petrifying gaze of Medusa.

description: A study of the adsorption of CO on late 4d and $5d$ transition metal (111) surfaces (Ru, Rh, Pd, Ag, Os, Ir, and Pt) considering atop and hollow site adsorption is presented. The applied functionals include the gradient corrected PBE and BLYP functional, and the corresponding hybrid Hartree-Fock density functionals HSE and B3LYP. We find that PBE based hybrid functionals (specifically HSE) yield, with the exception of Pt, the correct site order on all considered metals, but they also considerably overestimate the adsorption energies compared to experiment. On the other hand, the semi-local BLYP functional and the corresponding hybrid functional B3LYP yield very satisfactory adsorption energies and the correct adsorption site for all surfaces. We are thus faced with a Procrustean problem: the B3LYP and BLYP functionals seem to be the overall best choice for describing adsorption on metal surfaces, but they simultaneously fail to account well for the properties of the metal, vastly overestimating the equilibrium volume and underestimating the atomization energies. Setting out from these observations, general conclusions are drawn on the relative merits and drawbacks of various semi-local and hybrid functionals. The discussion includes a revised version of the PBE functional specifically optimized for bulk properties and surface energies (PBEsol), a revised version of the PBE functional specifically optimized to predict accurate adsorption energies (rPBE), as well as the aforementioned BLYP functional. We conclude that no semi-local functional is capable to describe all aspects properly, and including non-local exchange also only improves some, but worsens other properties.

Massive and Massless Neutrinos on Unbalanced Seesaws

description: The observation of neutrino oscillations requires new physics beyond the standard model (SM). A SM-like gauge theory with p lepton families can be extended by introducing q heavy right-handed Majorana neutrinos but preserving its SU(2)_L x U(1)_Y gauge symmetry. The overall neutrino mass matrix M turns out to be a symmetric (p+q) x (p+q) matrix. Given p>q, the rank of M is in general equal to 2q, corresponding to 2q non-zero mass eigenvalues. The existence of (p-q) massless left-handed Majorana neutrinos is an exact consequence of the model, independent of the usual approximation made in deriving the Type-I seesaw relation between the effective p x p light Majorana neutrino mass matrix M_νand the q x q heavy Majorana neutrino mass matrix M_R. In other words, the numbers of massive left- and right-handed neutrinos are fairly matched. A good example to illustrate this seesaw fair play rule is the minimal seesaw model with p=3 and q=2, in which one massless neutrino sits on the unbalanced seesaw.

description: This study investigated the intersection of social media and the "End Bad Government" movement among public senior secondary school students in Mangu Local Government Area (LGA), Plateau State and its implications for educational management. A descriptive survey research design was used for this study. The population of the study consisted of 3,100 registered teachers with the sample of 310 respondents (teachers) that is 10% from 10 secondary schools. A self-structured questionnaire titled “Intersection of Social Media and End Bad Government Movement among Public Senior Secondary School Students: Implications for Educational Management” (ISMEBGPSSSIMGQ) was used as the instrument for data collection. The instrument was validated by two experts, one from the department of Educational administration and planning and the other from the Department of Psychology and Guidance and Counseling, Federal University Dutsin-Ma, Katsina State. The data were analyzed using mean and standard deviation to answer research questions while the null hypothesis was tested using t-test statistics at 0.05 level of significance. The bench mark for decision making was 2.50. The study concludes by recommending enhanced dialogue between administrators and students, inclusive policy development and more

description: Cultural amenities are the expression of a cultural environment, given by a combination of aesthetic factors, styles, rhythms and behaviours, which contribute to make a neighbourhood vibrant and more enjoyable. Following the hedonic approach, we propose an empirical strategy to capture the multiple effects of cultural amenities, as well as the effects produced by green areas, public transport and university proximity. The results are used to determine whether cultural amenities are optimally provided by the municipality of Milan, Italy. It emerged that investments in culture generate positive effects to society, and that governments should devote far more resources to culture.

description: The quantum bit error rate is a key quantity in quantum communications. If the quantum channel is the atmosphere, the information is usually encoded in the polarization of a photon. A link budget is required, which takes into account the depolarization of the photon after its interaction with the atmosphere as well as absorption, scattering and atmospheric emissions. An experimental setup for the reproduction of a simple model of the atmosphere is used to evaluate the quantum bit error rate in a BB84 protocol and the results are presented. This result represents a first step toward the realization of an optical bench experiment where atmospheric effects are simulated and controlled for reproducing the effects on a quantum channel in different meteorological situations.

description: Using Spanish data, this paper shows that improvements in the road network have a positive effect on private investment in capital assets, and this effect increases with the level of economic development of a geographical area. We use aggregate data at the provincial level between the years 1977–2008. Additionally, we propose a system of equations in order to approximate the long-run effects. We find statistical evidence of efficiency loss associated with the distributional aims of the infrastructure policy. More importantly, since the effects of infrastructure investment are permanent, in the long run, efficiency costs will be higher.

description: We study Hamiltonian actions of compact Lie groups K on Kaehler manifolds which extend to a holomorphic action of the complexified group K^C. For a closed normal subgroup L of K we show that the Kaehlerian reduction with respect to L is a stratified Hamiltonian Kaehler K^C/L^C-space whose Kaehlerian reduction with respect to K/L is naturally isomorphic to the Kaehlerian reduction of the original manifold with respect to K.

description: The detection and parametrization of molecular clumps is the first step in studying them. We propose a method based on Local Density Clustering algorithm while physical parameters of those clumps are measured using the Multiple Gaussian Model algorithm. One advantage of applying the Local Density Clustering to the clump detection and segmentation, is the high accuracy under different signal-to-noise levels. The Multiple Gaussian Model is able to deal with overlapping clumps whose parameters can be derived reliably. Using simulation and synthetic data, we have verified that the proposed algorithm could characterize the morphology and flux of molecular clumps accurately. The total flux recovery rate in $^{13}\rm CO$ (J=1-0) line of M16 is measured as 90.2\%. The detection rate and the completeness limit are 81.7\% and 20 K km s$ ^{-1} $ in $^{13}\rm CO$ (J=1-0) line of M16, respectively.

description: In a recent Letter [B. K. Sahoo, B. P. Das, and H. Spiesberger, Phys. Rev. D 103, L111303 (2021)], a calculation of the parity violating 6S-7S E1 amplitude in Cs is reported, claiming an uncertainty of just 0.3%. In this Comment, we point out that key contributions have been omitted, and the theoretical uncertainty has been significantly underestimated. In particular, the contribution of missed QED radiative corrections amounts to several times the claimed uncertainty.
