description: We fit elliptical isophotes to the Hubble Deep Field-North WFPC-2 and NICMOS data to study the rest-frame UV_{218}-U_{300} color profiles and rest-frame B surface brightness profiles of 33 intermediate redshift galaxies (0.5 <= z <= 1.2) with I_{814} < 25 and 50 high redshift galaxies (2.0 <= z <= 3.5) with H_{160}< 27. From the weighted least-squares fit to the color profiles we find that, at intermediate redshifts, the galaxies possess negative color gradients indicating a reddening towards the center of the profile similar to local samples whereas, at high redshifts, the galaxies possess positive color gradients. This indicates that star formation is more centrally concentrated in the distant galaxy sample which differs from the prevalent mode of extended disk star formation that we observe in the local universe. Additionally, we find that it is critical to correct for PSF effects when evaluating the surface brightness profiles since at small scale lengths and faint magnitudes, an r^{1/4} profile can be smoothed out substantially to become consistent with an exponential profile. After correcting for PSF effects, we find that at higher look-back time, the fraction of galaxies possessing exponential profiles have slightly decreased while the fraction of galaxies possessing r^{1/4} profiles have slightly increased. Our results also suggest a statistically insignificant increase in the fraction of peculiar/irregular type galaxies. We compare our results with recent semi-analytical models which treat galaxy formation and evolution following the cold dark matter hierarchical framework.

description: The pair-condensed unpolarized spin-$1/2$ Fermi gases have a collective excitation branch in their pair-breaking continuum (V.A. Andrianov, V.N. Popov, 1976). We study it at zero temperature, with the eigenenergy equation deduced from the linearized time-dependent BCS theory and extended analytically to the lower half complex plane through its branch cut, calculating both the dispersion relation and the spectral weights (quasiparticle residues) of the branch. In the case of BCS superconductors, so called because the effect of the ion lattice is replaced by a short-range electron-electron interaction, we also include the Coulomb interaction and we restrict ourselves to the weak coupling limit $Δ/μ\to 0^+$ ($Δ$ is the order parameter, $μ$ the chemical potential) and to wavenumbers $q=O(1/ξ)$ where $ξ$ is the size of a pair; when the complex energy $z_q$ is expressed in units of $Δ$ and $q$ in units of $1/ξ$, the branch follows a universal law insensitive to the Coulomb interaction. In the case of cold atoms in the BEC-BCS crossover, only a contact interaction remains, but the coupling strength $Δ/μ$ can take arbitrary values, and we study the branch at any wave number. At weak coupling, we predict three scales, that already mentioned $q\approx 1/ξ$, that $q\approx(Δ/μ)^{-1/3}/ξ$ where the real part of the dispersion relation has a minimum and that $q\approx (μ/Δ)/ξ\approx k_{\rm F}$ ($k_{\rm F}$ is the Fermi wave number) where the branch reaches the edge of its existence domain. Near the point where the chemical potential vanishes on the BCS side, $μ/Δ\to 0^+$, where $ξ\approx k_{\rm F}$, we find two scales $q\approx(μ/Δ)^{1/2}/ξ$ and $q\approx 1/ξ$. In all cases, the branch has a limit $2Δ$ and a quadratic start at $q=0$. These results were obtained for $μ>0$, where the eigenenergy equation admits at least two branch points $ε_a(q)$ and $ε_b(q)$ on the positive real axis, and for an analytic continuation through the interval $[ε_a(q),ε_b(q)] $. We find new continuum branches by performing the analytic continuation through $[ε_b(q),+\infty[$ or even, for $q$ low enough, where there is a third real positive branch point $ε_c(q)$, through $[ε_b(q),ε_c(q)]$ and $[ε_c(q),+\infty[$. On the BEC side $μ<0$ not previously studied, where there is only one real positive branch point $ ε_a(q)$, we also find new collective excitation branches under the branch cut $[ε_a (q),+\infty[$. For $μ>0$, some of these new branches have a low-wavenumber exotic hypoacoustic $z_q\approx q^{3/2}$ or hyperacoustic $z_q\approx q^{4/5}$ behavior. For $μ<0$, we find a hyperacoustic branch and a nonhypoacoustic branch, with a limit $2Δ$ and a purely real quadratic start at $q=0$ for $Δ/|μ|<0.222$.

description: Supermassive Black Holes (BHs) residing in brightest cluster galaxies (BCGs) are overly massive when considering the local relationships between the BH mass and stellar bulge mass or velocity dispersion. Due to the location of these BHs within the cluster, large-scale cluster processes may aid the growth of BHs in BCGs. In this work, we study a sample of 71 galaxy clusters to explore the relationship between the BH mass, stellar bulge mass of the BCG, and the total gravitating mass of the host clusters. Due to difficulties in obtaining dynamically measured BH masses in distant galaxies, we use the Fundamental Plane relationship of BHs to infer their masses. We utilize X-ray observations taken by $Chandra$ to measure the temperature of the intra-cluster medium (ICM), which is a proxy for the total mass of the cluster. We analyze the $\rm M_{BH}-kT$ and $\rm M_{BH}-M_{Bulge}$ relationships and establish the best-fitting power laws:$\log_{10}(M_{\rm BH} /10^9 M_{\odot})=-0.35+2.08 \log_{10}(kT / 1 \rm keV)$ and $\log_{10}(\rm M_{BH}/10^9M_{\odot})= -1.09+ 1.92 \log_{10}(M_{\rm bulge}/10^{11}M_{\odot})$. Both relations are comparable with that established earlier for a sample of brightest group/cluster galaxies with dynamically measured BH masses. Although both the $\rm M_{BH}-kT$ and the $\rm M_{BH}-M_{Bulge}$ relationships exhibit large intrinsic scatter, based on Monte Carlo simulations we conclude that dominant fraction of the scatter originates from the Fundamental Plane relationship. We split the sample into cool core and non-cool core resembling clusters, but do not find statistically significant differences in the $\rm M_{BH}-kT$ relation. We speculate that the overly massive BHs in BCGs may be due to frequent mergers and cool gas inflows onto the cluster center.

description: This dissertation comprises three essays in behavioral and information economics. The first, “Estimating Information Cost Functions in Models of Rational Inattention,” uses laboratory data to analyze the properties of cost functions in models of rational inattention and determine their functional forms. The second, “Promises and Pronouncements,” uses a laboratory experiment to determine whether the propensity to tell monetarily advantageous lies depends on the ability to control the final outcome; in other words, whether reneging on a commitment (breaking a promise) is more or less likely than lying about something out of one’s control (making a false pronouncement). The third, “Costly Information and Multiattribute Choice” provides an information-theoretic explanation for some commonly observed phenomena in consumer choice when goods are defined by multiple characteristics.

description: Ausgehend von begrifflich-theoretischen Vorüberlegungen konturiert und analysiert dieser Beitrag die sozialen Träger der „bürgerlichen Gesellschaft“ und „Zivilgesellschaft“ in der Geschichte Deutschlands im 19. und 20. Jahrhundert. Darüber hinaus werden Handlungsformen dieser Akteure behandelt. Dabei tritt hervor, dass die Trägergruppen zivilgesellschaftlicher Werte und Praxen deutlich variierten. Die vergleichende Perspektive, die im Ausblick Indien und China einbezieht, stellt die Fixierung der (west)deutschen Forschung auf das Bürgertum noch nachhaltiger in Frage. Insgesamt wird hier argumentiert, dass in globalhistorischer Sicht jeweils funktionale Äquivalente zivilgesellschaftlicher Praxis und Akteure identifiziert werden müssen. Dabei sind aber unterschiedliche Kontexte und Aneignungen in Rechnung zu stellen, um die Varianz der Trägergruppen von Zivilität und deren Performanz erklären zu können. Insgesamt plädiert der Autor für ein handlungslogisches Verständnis von Zivilgesellschaft.

description: We present an analysis of CMDs of three intermediate-age LMC clusters, namely NGC 2173, SL 556 and NGC 2155. The main goal of our project is to investigate the amount of convective core overshoot necessary to reproduce the CMDs of relatively metal-poor, intermediate age stellar populations. We conclude that a moderate amount of overshoot and some fraction of binary stars are essential for reproducing the observed shapes around the turnoff in the CMD's of all three clusters: unresolved binary stars fill in the expected core contraction gap, and make a unique sequence near the gap, which cannot be reproduced by single stars alone, even with a larger amount of overshoot. From our overall analysis such as, shape of isochrones, star counts, color distribution, and synthetic CMD comparisons, we conclude that overshoot ~ 20% of the local pressure scale height best reproduces the CMD properties of all three clusters. The best age estimates are 1.5, 2.1 and 2.9 Gyr for NGC 2173, SL 556 and NGC 2155, respectively.

description: Polemon collaris (Peters, 1881)
 Material (one specimen): One adult specimen (MHNCUP/REP 170, formerly UP-MHNFCP-017414; Fig. S60), collected from Golungo Alto [-9.13333º, 14.76667º, 666 m a.s.l.] Kwanza Norte Province, date unknown.
 Comments: Polemon collaris is a forest dwelling species found from Nigeria to Uganda and south into western Angola (Branch 2018; Marques et al. 2018). The label present in the jar reads “ Microsoma collare ” but has no information regarding the collecting locality, however Ferreira (1906) cited an adult specimen of Bocage’s (1895) “form B ” from “Golungo Alto”, which most likely represents this specimen. After comparing Bocage’s original description and plate to MHNCUP/REP 170, we find the specimen to match the same morphology. Boulenger (1905), de Witte & Laurent (1947) and Hellmich (1957) cited specimens from the same locality. Recently, Portilo et al. (2018) reported a specimen from “North-west” Angola, but according to Conradie (pers. comm.), the correct locality is “Camp Chiri, Saurimo Region, Lunda Norte Province).

description: We consider a partially hinged rectangular plate and its normal modes. The dynamical properties of the plate are influenced by the spectrum of the associated eingenvalue problem. In order to improve the stability of the plate, it seems reasonable to place a certain amount of stiffening material in appropriate regions. If we look at the partial differential equation appearing in the model, this corresponds to insert a suitable weight coefficient inside the equation. A possible way to locate such regions is to study the eigenvalue problem associated to the aforementioned weighted equation. In the present paper we focus our attention essentially on the first eigenvalue and on its minimization in terms of the weight. We prove the existence of minimizing weights inside special classes and we try to describe them together with the corresponding eigenfunctions.

description: From the analyticity properties of the equation governing infinitesimal perturbations, it is shown that all stability properties of spatially extended 1D systems can be derived from a single function that we call entropy potential since it gives directly the Kolmogorov-Sinai entropy density. Such a function allows determining also Lyapunov spectra in reference frames where time-like and space-like axes point in general directions in the space-time plane. The existence of an entropy potential implies that the integrated density of positive exponents is independent of the reference frame.

description: Social inequalities have conventionally been researched as synchronous processes within the frame of national borders and articulated in the concept of class. This means that established scholarship has not adequately considered the historical dimensions and global entanglements or interconnections between class and other social classifications that have shaped existing inequalities. Starting from world system and postcolonial theories as well as from recent debates on transnationalism, the paper first presents a set of resources for overcoming current deficits in the research of inequalities. In order to illustrate how these resources analytically operate, the second part of the paper discusses the case of social inequalities which affect Afrodescendants in Latin America.

description: The parameters of the original log-normal mass spectrum of primordial black holes (PBH) are approximately adjusted on the basis of existing observational data on supermassive black holes in the galactic centers and the mass distribution of the near-solar mass black holes in the Galaxy. Together with the assumption that PBHs make all or a noticeable mass fraction of the cosmological dark matter, it allows to fix the parameters of the original mass spectrum. The predicted, in this way, the number density of MACHOs is found to be about an order of magnitude below the observed value. A possible resolution of this controversy may be prescribed to the non-isotropic and inhomogeneous distribution of MACHOs or to the modification of the original spectrum, e.g. assuming a superposition of two-maximum log-normal spectra of PBHs. A competing possibility is that MACHOs are not PBHs but dead primordial compact stars.

 Material (one specimen): One adult specimen (MHNCUP/REP 165, formerly UP-MHNFCP-017401; Fig. S61), collected from Bahia dos Tigres [= Baía dos Tigres] (in error) [-16.58559º, 11.82709º, 98 m a.s.l.] Namibe Province, by Francisco Newton in 1905.
 Comments: Boaedon angolensis is a species endemic to Angola that occurs in the highlands of Cuando Cubango, Uíge, Malanje, Huambo, Kwanza Norte and Huíla provinces (potentially Benguela and Cunene as well) (Marques et al. 2018; Hallermann et al. 2020). It was recently revised by Hallermann et al. (2020) as part of a larger study on the Boaedon genus in Angola. The authors revalidated the taxon as a full species and designated a neotype, given that the original type specimens used to describe Boaedon lineatus var. angolensis Bocage, 1895 had been lost in 1978 MBL fire. The presented specimen was not cited by Ferreira (1904, 1906), but the naturalist identified it as “ Boodon lineatus ”.

description: Twin-field quantum key distribution (TF-QKD) and its variant protocols are highly attractive due to the advantage of overcoming the rate-loss limit for secret key rates of point-to-point QKD protocols. For variations of TF-QKD, the key point to ensure security is switching randomly between a code mode and a test mode. Among all TF-QKD protocols, their code modes are very different, e.g. modulating continuous phases, modulating only two opposite phases, and sending or not sending signal pulses. Here we show that, by discretizing the number of global phases in the code mode, we can give a unified view on the first two types of TF-QKD protocols, and demonstrate that increasing the number of discrete phases extends the achievable distance, and as a trade-off, lowers the secret key rate at short distances due to the phase post-selection.

description: We study the Poincaré series of the quantum spaces associated to a Hecke operator, i.e., a Yang-Baxter operator satisfying the equation $(x+1)(x-q)=0$. The Poincaré series of the corresponding matrix bialgebra is also considered. Using an old result on Polyá frequency sequence, we show that the Poincaré series of quantum spaces are always rational functions having negative roots and positive poles. In particular, we show that the rank of an even Hecke operator should be rational functions having negative roots and positive poles. In particular, we show that the rank of an even Hecke operator should be greater than the dimension of the vector space it is acting on.

description: It has been found that helium gas can stabilize the THF hydrate (of the sII type). Dissociation temperatures of the binary He-THF hydrates are significantly higher than those of pure THF hydrates at the same pressure. In order to investigate the distribution of He molecules within the cavities of this hydrate, Grand Canonical Monte Carlo simulations have been utilized. A wide pressure range (up to 700 MPa) has been examined. The results of these simulations show that the small cavity of the binary He-THF hydrate is able to accommodate up to three He molecules resulting in a He content of 6.0 wt. % at 700 MPa. Contrary to the similar case of binary H2-THF hydrate, He content as a function of pressure does not present a plateau, at least over the pressure range examined. Moreover, similar simulations on a hypothetical sII hydrate of pure He show that the large cavity of this hydrate could be occupied by up to ten He molecules in the pressure range under question.

description: This study investigated multiple mating in three species of intertidal klipfishes (family Clinidae): super klipfish Clinus superciliosus, bluntnose klipfish Clinus cottoides, and nosestripe klipfish Muraenoclinus dorsalis. These species display the rare reproductive mode of female vivipary with superfetation, a phenomenon where offspring at various stages of development are found within the female. Three or four microsatellite loci were used to genotype 25–30 adults of each species, as well as embryos of 131 C. superciliosus from six broods, 103 C. cottoides from six broods, and 63 M. dorsalis from five broods. The presence of multiple mating by females was assessed by maximum-likelihood sibship reconstruction implemented in the program COLONY, and the non-random distribution of reproductive success among individuals (reproductive skew) within broods was tested using the binomial skew index. Multiple mating by females was pervasive and observed in 83%, 100% and 80% of the broods of C. superciliosus, C. cottoides and M. dorsalis, respectively. The mean number of sires per brood was 4.3, 3.0 and 3.2, and, correspondingly, 5/5, 5/6 and 1/4 of multiply-sired broods showed significant reproductive skew in C. superciliosus, C. cottoides and M. dorsalis, respectively. The presence of pronounced reproductive skew may indicate post-copulatory processes taking place that bias paternity. We compared our results on multiple mating within the klipfish family, and with four other fish families that have vivipary with superfetation, and found the klipfish patterns were among those of live-bearing vertebrate groups with the highest average numbers of sires per brood.

We show how an N-soliton solution can be used to construct ``sine-Gordon'' coordinates for a black hole of mass M, and construct the transformation to more standard ``Schwarzchild-like'' coordinates. For N=1 and 2, we find explicit closed form solutions to the dilaton equations of motion in soliton coordinates, and find the relationship between the soliton parameters and the black hole mass. Remarkably, the black hole mass is non-negative for arbitrary soliton parameters. In the one-soliton case the coordinates are shown to cover smoothly a region containing the whole interior of the black hole as well as a finite neighbourhood outside the horizon. A Hamiltonian analysis is performed for slicings that approach the soliton coordinates on the interior, and it is shown that there is no boundary contribution from the interior. Finally we speculate on the sine-Gordon solitonic origin of black hole statistical mechanics.

title: The Role of Backreef Soundscapes and their Spatial Structure for Recruitment of Tropical Marine Larvae
Creators: name: Anderson, Emily R.
Publisher: name: Old Dominion University Libraries
Year: 2021

description:
Underwater sound is a cue used by many marine larvae to orient to coastal habitats including backreef, sponge-dominated hardbottom habitat in the Florida Keys (Florida, USA) – a particularly “noisy” coastal habitat. However, the distance over which acoustic cues are attractive to settlement-stage larvae - is generally unknown. I examined this phenomenon in a region of the Florida Keys where mass sponge die-offs have diminished both underwater soundscapes and larval settlement. The absence of pronounced hardbottom-associated sound over such a large area allowed me to experimentally test in situ the response of fish and invertebrate larvae to broadcasted sounds at different distances from their source. I first measured sound recording from healthy hardbottom habitat at seven distances from an underwater speaker to determine the maximum range of the signal. Based on those results, larval collectors were then deployed at 10, 100, 500, and 1000 m from speakers broadcasting sounds recorded at either degraded or healthy hardbottom sites for five consecutive nights during each of three new and full moon periods in summer/fall 2019. Larval settlement onto those collectors was affected by lunar phase and soundscape type, but the effect of distance on larval settlement varied among species and, in most cases, the effect was small and not likely to be ecologically significant. The absence of a strong larval settlement response to a sound cue lies in contrast to results from other studies. I hypothesize that the small (<500 >m) radius of the broadcasted soundscapes may have limited the magnitude of the larval response to locally available larvae and because the experiment within a large, relatively quiet seascape where local larval abundance may have been low. If so, then planktonic larvae may require a series of acoustic “sign-posts”, perhaps in combination with other cues (e.g., chemical), to successfully orient to distant nursery habitats. Although habitat restoration efforts may be able to restore healthy soundscapes, the typically small size and number of restoration sites may limit the range of the acoustic cue and larval attraction to restored habitats.
Essays in Internal and International Migration

description: This dissertation investigates how internal migration spreads local shocks to the national market. The first chapter describes a dynamic model of internal migration where in equilibrium there are always positive internal migration flows across locations. When a shock in one of these location happens, internal migration flows are diverted away from the shocked locations, spreading the shock nationally. The second chapter explains how this is the main mechanism through which international migration is absorbed. The third chapter, documents how this exact same mechanism helps to mitigate the disproportionate effect that the Great Recession had on particular locations.

description: A search for heavy neutral Higgs bosons produced in association with one or two $b$-quarks and decaying to $b$-quark pairs is presented using 27.8 fb$^{-1}$ of $\sqrt{s}=13$ TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider during 2015 and 2016. No evidence of a signal is found. Upper limits on the heavy neutral Higgs boson production cross-section times its branching ratio to $b\bar{b}$ are set, ranging from 4.0 to 0.6 pb at 95% confidence level over a Higgs boson mass range of 450 to 1400 GeV. Results are interpreted within the two-Higgs-doublet model and the minimal supersymmetric Standard Model.

description: In many physically realistic models of quantum computation, Pauli exchange interactions cause a subset of two-qubit errors to occur as a first order effect of couplings within the computer, even in the absence of interactions with the computer's environment. We give an explicit 9-qubit code that corrects both Pauli exchange errors and all one-qubit errors.

Pseudogap suppression by competition with superconductivity in La-based cuprates
Creators: name: Küspert, Julia
Publisher: name: American Physical Society
Year: 2022
Subjects: cuprates

description: We carried out a comprehensive high-resolution angle-resolved photoemission spectroscopy (ARPES) study of the pseudogap interplay with superconductivity in La-based cuprates. The three systems La2−xSrxCuO4, La1.6−xNd0.4SrxCuO4, and La1.8−xEu0.2SrxCuO4 display slightly different pseudogap critical points in the tem- perature versus doping phase diagram. We studied the pseudogap evolution into the superconducting state for doping concentrations just below the critical point. In this setting, near optimal doping for superconductivity and in the presence of the weakest possible pseudogap, we uncover how the pseudogap is partially suppressed inside the superconducting state. This conclusion is based on the direct observation of a reduced pseudogap energy scale and re-emergence of spectral weight suppressed by the pseudogap. Altogether these observations suggest that the pseudogap phenomenon in La-based cuprates is in competition with superconductivity for antinodal spectral weight.

 Material (four specimens): One adult specimen (MHNCUP/REP 164, formerly UP-MHNFCP-017399), collected from unknown locality, date unknown; one adult specimen (MHNCUP/REP 166, formerly UP-MHNFCP-017397; Fig. S62), collected from unknown locality, date unknown; one adult specimen (MHNCUP/REP 167, formerly UP-MHNFCP-017400), collected from Novo Redondo [= Sumbe] [-11.20000º, 13.85000º, 11 m a.s.l.] Kwanza Sul Province, in September 1903; one adult specimen (MHNCUP/REP 168, formerly UP-MHNFCP-017402), collected from Bahia dos Tigres [= Baía dos Tigres] [-16.58559º, 11.82709º, 98 m a.s.l.] Namibe Province (in error), in 1903.
 Comments: Boaedon bocagei is an Angolan endemic species that is currently known from the coastal lowlands of the country, namely Luanda, Bengo, Zaire and Kwanza Sul provinces (Hallermann et al. 2020). Ferreira (1904) reported adult and juvenile specimens of “ Boodon lineatu s” from “Novo Redondo” (MHNC-UP/REP167), “Lembu (Serra de Selles)” and “Cacullo” and later a specimen from “Rio Luinha” (Ferreira 1906). Boaedon bocagei was recently described as a new species by Hallermann et al. (2020) in their revision of the Boaedon from Angola. The authors designated specimens MHNCUP/REP 166–168 from the Newton Expedition as paratypes, although considering them all to be from Novo Redondo, as Baía dos Tigres was in error as locality and specimen MHNCUP/ REP 164 likely corresponds to the published one from Rio Luinha, given its pattern (Ferreira 1906).

title: The Fabric of Art: Investigating the Relationships of Power Between Fabric & Fine Art Through Frank Stella's 'Black Paintings' (1958-1960)
Creators: name: Mackenzie, Jewel
Publisher: name: Griffith University
Year: 2005
Subjects: subject: Fabric in fine art
subject: Frank Stella
subject: fabric as a medium
subject: sewing as fine art

description: There are two inter-related parts to the hypothesis explored in this research. The first is that it is significant to employ fabric as a medium in a fine art context, and the second aspect argues that female artists who choose fabric as their medium should be recognised as 'artists' rather than as crafts practitioners. I propose that in choosing fabric as a medium and sewing as my method of making art, I am working within the framework of contemporary fine art practice. In his essay 'To Cut is to Think' Germano Celant succinctly described the 'cut' made by artists who choose cutting as their process: The cut of the scissor is like the click of a camera or the whirr of a movie camera, like a stroke of the pencil or paintbrush: all these acts decisively isolate a form or representation, marking a surface that generates a reality. The cut puts an end to the traditional representation of the image, dissolving it and then restoring it as a testimony to the artist's vision and understanding. In this light, the cut confers meaning, and its use unites artists, photographers, designers and tailors, who cut their visions from the magma of their materials, whether these be colour or bronze, fabric or film, metal or wool, wood or canvas (1996, p. 31). My own use of the cut, as the bespoke tailor, reinterpreted fabric as paint and utilized pinstriped fabric as a visual metaphor for relationships of power, pink satin as a symbol of the female inclusion and Frank Stella's Black Paintings as a tool to position my work. Therefore, I would claim that I am working towards a conceptual repositioning of fabric as a medium in fine art.

description: Ecumicin and rufomycin 4-7 disrupt protein homeostasis in Mycobacterium tuberculosis by inhibiting the proteolytic activity of the ClpC1/ClpP1/ClpP2 complex. Although these compounds target ClpC1, their effects on the ATPase activity of ClpC1 and proteolytic activity of ClpC1/ClpP1/ClpP2 vary. Herein, we explored the ClpC1 molecular dynamics with these compounds through fluorescence correlation spectroscopy. The effect of these compounds on the ATPase activity of ClpC1-cys, the recombinant protein for fluorescence labeling, and proteolytic activity of ClpC1-cys/ClpP1/ClpP2 were identical to those of native ClpC1, whereas the intermolecular dynamics of fluorescence-labelled ClpC1 were different. Treatment with up to 1 nM ecumicin increased the population of slower diffused ClpC1 components compared with ClpC1 without ecumicin. However, this population was considerably reduced when treated with 10 nM ecumicin. Rufomycin 4-7 treatment resulted in a slower diffused component of ClpC1, and the portion of this component increased in a concentration-dependent manner. Ecumicin can generate an abnormal ClpC1 component, which cannot form normal ClpC1/ClpP1/ClpP2, via two different modes. Rufomycin 4-7 only generates slower diffused ClpC1 component that is inadequate to form normal ClpC1/ClpP1/ClpP2. Overall, we demonstrate that ecumicin and rufomycin 4-7 use different action mechanisms to generate abnormal ClpC1 components that cannot couple with ClpP1/ClpP2.
