description: Testudo scripta Thunberg in Schoepff 1792
 The specimen of “ Testudo scabra Thunberg ” (labeled “ Testudo scripta Thunberg ” on the plate) that Schoepff (1792) used as the basis for the description of Testudo scripta (= Trachemys scripta scripta) is present in the Thunbergian collection in Uppsala (Fig. 7). It is the only specimen of Testudo scripta in the collection and was accessioned by Thunberg himself, who recorded it in various versions of his museum catalogues. This specimen is the holotype of Trachemys scripta scripta and has never previously been located or identified (Iverson 1992; Seidel and Ernst 2006). Interestingly, Schweigger (1812:297) later wrote about T. scripta Schoepff: “ Vidi specimen, quo usus Schoepf., in museo Parisiensi ” (I saw the specimen, used by Schoepff, in the Paris Museum), but that was never confirmed, and it is not there (R. Bour, pers. comm.). Instead, it was part of the Thunberg donation to the collections in Uppsala. Since Schweigger visited both collections, he may have meant “ Upsaliensi ” rather than “ Parisiensi.”
 The specimen is a small, dried, misshapen hatchling labeled “ Testudo scripta Mus. Thunb. ” by Thunberg himself (Fig. 7) and is the only T. scripta in the entire Linnaean and Thunbergian collections in Uppsala. It measures approximately 31.0 mm straight CL, ca. 30.3 mm PL, and 9.2 mm tympanic head width, and has a trace of its hatchling egg caruncle still visible. It was never given an original accession number, but has now been catalogued as UUZM Types 7455. It was accessioned into the Uppsala collection sometime between 1785 and 1792, but not with the first group of Thunberg specimens in 1785, being added to the catalogue as “ Testudo scripta ” after the initial entries (Thunberg 1785 –1817, 1808–1815). Aside from entries for this single specimen of T. scripta by Thunberg in various other handwritten museum catalogues, the only actual publication documenting its existence was in Thunberg (1818) where it was listed as being part of the Thunberg donations to the Uppsala collections.
 Based on examination of the poorly-preserved holotype and its photos (Fig. 7) and examination of its original figure (Schoepff 1792: pl. 3, f. 4, 5, labeled “ Test. scripta Thunb.”) (Fig. 4), we and other colleagues highly familiar with T. scripta (K. Buhlmann, W. Gibbons, and B. Thomas, pers. comm.) agree that it fortunately appears to represent a Trachemys scripta scripta, but genetic analysis would be helpful to be certain.

description: Viral fibers play a central role in many virus infection mechanisms since they recognize the corresponding host and establish a mechanical link to its surface. Specifically, bacteriophages have to anchor to bacteria through the fibers surrounding the tail before starting the viral DNA translocation into the host. The protein gene product (gp) 37 from bacteriophage T4 long tail fibers forms a fibrous parallel homotrimer located at the distal end of the long tail fibers. Biochemical data indicate that, at least three of these fibers are required for initial host cell interaction, but do not reveal why three and no other number. By using Atomic Force Microscopy we obtained high-resolution images of gp37 fibers adsorbed on mica substrate in buffer conditions and probed their local mechanical properties. Our experiments of radial indentation at the nanometer scale provided a radial stiffness of ~0.08 N/m and a breaking force of ~120 pN. In addition, we performed Finite Element Analysis and determined a Young's modulus of ~20 MPa. From these mechanical parameters, we hypothesize that three viral fibers provide enough mechanical strength to prevent a T4 virus from being detached from the bacteria by the viral particle Brownian motion, delivering a biophysical justification of the previous biochemical data.
Efficient harvesting of fish stocks : the case of the Icelandic demersal fisheries
Creators: name: Arnason, Ragnar
Publisher: name: University of British Columbia
Year: 2010

description: A detailed model describing the economics of harvesting self-renewable resources is constructed. The model is developed in terms of the particular case of the Icelandic demersal fisheries. Its basic structure is nevertheless general enough to apply to a wide range of other self-renewable natural resources. The model involves a biological submodel, describing the internal dynamics of the resources, an economic submodel, describing the technology and dynamics of the harvesting process, and a special function providing the link between these two submodels. Ecological interactions are represented by a mixture of deterministic and stochastic relations. The model is designed to cope with any finite number of self-renewable resources and harvesting technologies. In terms of fisheries it may thus be characterized as a multi-species, multi-fleet model. The particular empirical case investigated, involves 3 species of fish and 2 types of fishing vessels. An objective function, mapping harvesting results into efficiency levels is defined. Basically, this function specifies harvesting paths that maximize discounted economic rents as efficient. With the help of numerical search techniques, the model is employed to discover efficient harvesting paths for the Icelandic demersal fisheries. The control variables in this maximization process are (i) investment in the fishing fleets and (ii) the allocation of the fleets to fisheries and/or idleness. For the case of the Icelandic demersal fisheries, it is demonstrated that the current harvesting pattern is very inefficient and that an efficient harvesting path involves a significant reduction in overall fishing capital as well as a reallocation of the fishing fleets to the various fisheries. The sensitivity of the efficient harvesting path to various model specifications is briefly investigated. Finally, the model is used to investigate the properties of efficient harvesting paths under a number of economic and ecological specifications not necessarily related to the Icelandic demersal fisheries. One notable result of this investigation is that the existence of significant ecological interactions may invalidate certain economic relationships that are often taken for granted.

description: Text of a conference held at Ferrara University (May 2006) on  ethnobiology and its possible application to classical studies. After a  brief introduction to the field, the author focuses on the difference  between primary and secondary folkbiological names, stressing the  properties of descriptiveness and transparency typical of the latter.  Secondary folkbiological terms are further analyzed into four  typologies, by way of linguistic patterns drawn from generative  morphology. This provides a basis for describing the application of the  given analytical model to a corpus of ethnobiological data collected  from written sources, as it is the case with the cultures involved here.  Some examples from ancient Greek and Latin folkbiology clarify these  and further issues (e. g. those connected with tracing taxonomical  features selected as distinctive of a given biological referent).

description: Using the local density approximation and its combination with dynamical mean-field theory, we show that electronic correlations induce a single-sheet, cuprate-like Fermi surface for hole-doped 1/1 LaNiO3 /LaAlO3 heterostructures, even though both eg orbitals contribute to it. The Ni 3d 3z^2-1 orbital plays the role of the axial Cu 4s-like orbital in the cuprates. These two results indicate that "orbital engineering" by means of heterostructuring should be possible. As we also find strong antiferromagnetic correlations, the low-energy electronic and spin excitations in nickelate heterostructures resemble those of high-temperature cuprate superconductors.

description: Two different scenarios of the quantum critical point (QCP), a zero-temperature instability of the Landau state, related to the divergence of the effective mass, are investigated. Flaws of the standard scenario of the QCP, where this divergence is attributed to the occurrence of some second-order phase transition, are demonstrated. Salient features of a different {\it topological} scenario of the QCP, associated with the emergence of bifurcation points in equation $ε(p)=μ$ that ordinarily determines the Fermi momentum, are analyzed. The topological scenario of the QCP is applied to three-dimensional (3D) Fermi liquids with an attractive current-current interaction.

description: Obtaining accurate photometric redshift estimations is an important aspect of cosmology, remaining a prerequisite of many analyses. In creating novel methods to produce redshift estimations, there has been a shift towards using machine learning techniques. However, there has not been as much of a focus on how well different machine learning methods scale or perform with the ever-increasing amounts of data being produced. Here, we introduce a benchmark designed to analyse the performance and scalability of different supervised machine learning methods for photometric redshift estimation. Making use of the Sloan Digital Sky Survey (SDSS - DR12) dataset, we analysed a variety of the most used machine learning algorithms. By scaling the number of galaxies used to train and test the algorithms up to one million, we obtained several metrics demonstrating the algorithms' performance and scalability for this task. Furthermore, by introducing a new optimisation method, time-considered optimisation, we were able to demonstrate how a small concession of error can allow for a great improvement in efficiency. From the algorithms tested we found that the Random Forest performed best in terms of error with a mean squared error, MSE = 0.0042; however, as other algorithms such as Boosted Decision Trees and k-Nearest Neighbours performed incredibly similarly, we used our benchmarks to demonstrate how different algorithms could be superior in different scenarios. We believe benchmarks such as this will become even more vital with upcoming surveys, such as LSST, which will capture billions of galaxies requiring photometric redshifts.

description: Average atom (AA) models allow one to efficiently compute electronic and optical properties of materials over a wide range of conditions and are often employed to interpret experimental data. However, at high pressure, predictions from AA models have been shown to disagree with results from ab initio computer simulations. Here we reconcile these deviations by developing an innovative type of AA model, AVION, that computes the electronic eigenstates with novel boundary conditions within the ion sphere. Bound and free states are derived consistently. We drop the common AA image that the free-particle spectrum starts at the potential threshold, which we found to be incompatible with ab initio calculations. We perform ab initio simulations of crystalline and liquid carbon and aluminum over a wide range of densities and show that the computed band structure is in very good agreement with predictions from AVION.

description: A large population of intermediate-separation binaries, consisting of a main-sequence (MS) star and a white dwarf (WD), has recently emerged from Gaia's third data release (DR3), posing challenges to current models of binary evolution. Here we examine the $s$-process element abundances in these systems using data from GALAH DR3. Following refined sample analysis with parameter estimates based on GALAH spectra, we find a distinct locus where enhanced $s$-process elements depend on both the WD mass and metallicity, consistent with loci identified in previous asymptotic giant branch (AGB) nucleosynthesis studies with higher $s$-process yields. Notably, these enhanced abundances show no correlation with the systems' orbital parameters, supporting a history of accretion in intermediate-separation MS+WD systems. Consequently, our results form a direct observational evidence of a connection between AGB masses and $s$-process yields. We conclude by showing that the GALAH DR3 survey includes numerous Ba dwarf stars, within and beyond the mass range covered in our current sample, which can further elucidate $s$-process element distributions in MS+WD binaries.

description: We present a detailed study of the longitudinal proximity effect using a sample of 85 quasars spanning an emission redshift range of $3.5 \leq z_{em} \leq 4.5$ and Lyman continuum luminosity ($L_{912}$) ranging from 1.06$\times 10^{31}$ to 2.24$\times 10^{32}$ erg s$^{-1}$ Hz$^{-1}$. We use the high-quality spectra of these quasars obtained at a spectral resolution of $R\sim$ 5100 and S/N $\sim$ 30 using X-SHOOTER spectrograph mounted on the Very Large Telescope (VLT). In our analysis, we compared the transmitted flux and pixel optical depth of the Ly$α$ absorption originating from the vicinity of quasars to those from the general intergalactic medium by using a redshift matched control sample. The longitudinal proximity effect is found up to $r \leq 12$ Mpc (proper) from quasars. By appropriately scaling up the pixel optical depth in the vicinity of quasars to account for the excess ionization by quasars, we constrain the ratio of median HI optical depth in the vicinity of the quasar to that of the IGM ($R_τ(r)$). The $R_τ(r)$ is found to be significantly higher than unity up to 6 Mpc from the quasar with a typical radial profile of the form $R_τ(r) = 1+A \times exp(-r/r_0)$ with $A=9.16\pm 0.68$ and $r_0= 1.27\pm 0.08$ Mpc. The integrated value of the scaled pixel optical depth over the radial bin of 0-6 Mpc is found to be higher by a factor of $2.55 \pm 0.17$ than the corresponding integrated value of the median pixel optical depth of the IGM. We also found $R_τ(r)$ to be luminosity dependent.

description: The imaginary-time path integral representation of the canonical partition function of a quantum system and non-equilibrium work fluctuation relations are combined to yield methods for computing free energy differences in quantum systems using non-equilibrium processes. The path integral representation is isomorphic to the configurational partition function of a classical field theory, to which a natural but fictitious Hamiltonian dynamics is associated. It is shown that if this system is prepared in an equilibrium state, after which a control parameter in the fictitious Hamiltonian is changed in a finite time, then formally the Jarzynski non-equilibrium work relation and the Crooks fluctuation relation are shown to hold, where work is defined as the change in the energy as given by the fictitious Hamiltonian. Since the energy diverges for the classical field theory in canonical equilibrium, two regularization methods are introduced which limit the number of degrees of freedom to be finite. The numerical applicability of the methods is demonstrated for a quartic double-well potential with varying asymmetry. A general parameter-free smoothing procedure for the work distribution functions is useful in this context.

description: The polarisation Sagnac speedmeter interferometer has the potential to replace the Michelson interferometer as the instrumental basis for future generations of ground-based gravitational wave detectors. The quantum noise benefit of this speedmeter is dependent on high-quality polarisation optics, the polarisation beam-splitter (PBS) and quarter-waveplate (QWP) optics that are key to this detector configuration and careful consideration of the effect of birefringence in the arm cavities of the interferometer. A PBS with an extinction ratio of better than 4000 in transmission and 700 in reflection for a $41^{\circ}$ angle of incidence was characterised along with a QWP of birefringence of $\fracλ{4} + \fracλ{324}$. The cavity mirror optics of a 10m prototype polarisation Sagnac speedmeter were measured to have birefringence in the range $1\times10^{-3}$ to $2\times10^{-5}$ radians. This level of birefringence, along with the QWP imperfections, can be canceled out by careful adjustment of the QWP angle, to the extent that the extinction ratio of the PBS is the leading limitation for the polarisation Sagnac speedmeter in terms of polarisation effects.

description: Exploiting recently obtained analytic solutions of classical Yang-Mills equations for higher order perturbations in the field of the dilute object (proton), we derive the complete first saturation correction to the single inclusive semi-hard gluon production in high energy proton-nucleus collisions by applying the Lehmann-Symanzik-Zimmermann reduction formula. We thus finalize the program started by Balitsky (see Ref.~\cite{Balitsky:2004rr}) and independently by Chirilli, Kovchegov and Wertepny (see Ref.~\cite{Chirilli:2015tea}) albeit using a very different approach to carry out our calculations. We extracted the functional dependence of gluon spectrum on the color charge densities of the colliding objects; thus our results can be used to evaluate complete first saturation correction to the double/multiple inclusive gluon productions.

description: We study the asymptotic behaviour of the orbit-counting function and a dynamical Mertens' theorem for the full $G$-shift for a finitely-generated torsion-free nilpotent group $G$. Using bounds for the M{ö}bius function on the lattice of subgroups of finite index and known subgroup growth estimates, we find a single asymptotic of the shape \[ \sum_{|τ|\le N}\frac{1}{e^{h|τ|}}\sim CN^α(\log N)^β \] where $|τ|$ is the cardinality of the finite orbit $τ$. For the usual orbit-counting function we find upper and lower bounds together with numerical evidence to suggest that for actions of non-cyclic groups there is no single asymptotic in terms of elementary functions.

description: This work addresses the early stages ($\le$1000 h) of the dissolution corrosion behavior of 316L and DIN 1.4970 austenitic stainless steels in contact with oxygen-poor (C$_O$ < 10$^-$$^8$ mass%), static liquid lead-bismuth eutectic (LBE) at 500°C for 600-1000 h. The objective of this study was to determine the relative early-stage resistance of the uncoated steels to dissolution corrosion and to assess the protectiveness of select candidate coatings (Cr$_2$AlC, Al$_2$O$_3$, V$_2$Al$_x$C$_y$). The simultaneous exposure of steels with intended differences in microstructure and thermomechanical state showed the effects of steel grain size, density of annealing/deformation twins, and secondary precipitates on the steel dissolution corrosion behavior. The findings of this study provide recommendations on steel manufacturing with the aim of using the steels to construct Gen-IV lead-cooled fast reactors.

description: The matrix product state (MPS) ansatz offers a promising approach for finding the ground state of molecular Hamiltonians and solving quantum chemistry problems. Building on this concept, the proposed technique of quantum circuit MPS (QCMPS) enables the simulation of chemical systems using a relatively small number of qubits. In this study, we enhance the optimization performance of the QCMPS ansatz by employing the variational quantum imaginary time evolution (VarQITE) approach. Guided by McLachlan's variational principle, the VarQITE method provides analytical metrics and gradients, resulting in improved convergence efficiency and robustness of the QCMPS. We validate these improvements numerically through simulations of $\rm H_2$, $\rm H_4$, and $\rm LiH$ molecules. Additionally, given that VarQITE is applicable to non-Hermitian Hamiltonians, we evaluate its effectiveness in preparing the ground state of transcorrelated (TC) Hamiltonians. This approach yields energy estimates comparable to the complete basis set (CBS) limit while using even fewer qubits. Specifically, we perform simulations of the beryllium atom and $\rm LiH$ molecule using only three qubits, maintaining high fidelity with the CBS ground state energy of these systems. This qubit reduction is achieved through the combined advantages of both the QCMPS ansatz and transcorrelation. Our findings demonstrate the potential practicality of this quantum chemistry algorithm on near-term quantum devices.

description: Desire is characterized by fluctuations in quality and quantity in most people, but sometimes these changes may result in a psychiatric condition. The spectrum of possible alterations is wide, and it may be  characterized by very different clinical pictures.

The main role of the neurobiological mechanisms that underlie desire is played by dopamine, a neurotransmitter whose concentration can be modified by use or abuse of several compounds, which may have a therapeutic role, in the case of medicines, or may lead to dysfunctional situations, in the case of substances or alcohol.

Neuroimaging studies have allowed a better knowledge of brain areas involved in mental illnesses, recording functional changes during the execution of specific tasks. The improvement of these techniques in the near future will improve the choice of the most appropriate treatment for each disease, leading to patient tailored therapies.

Different approaches to the treatment of disorders associated with an alteration of desire are currently available; often their combination, such as the one between psychophamacological drugs and psychotherapy, can lead to a better therapeutic result and to a reduction, or mitigation, of episodes’ of severity and recurrences.

Cependant, bien que les banques aient modernisé leurs activités en proposant à leurs clients le Mobile Banking, une frange importante de ceux-ci tarde encore à l’adopter. La présente recherche se propose d’étudier l’influence des caractéristiques psychologiques et fonctionnelles des innovations sur la résistance des clients à l’égard des SBM. Pour cette fin, à l’aide d’une modélisation par équations structurelles et des données collectées auprès d’un échantillon de 520 clients bancaires, il en ressort globalement que les caractéristiques psychologiques à savoir la tradition et l’image influencent positivement la résistance des clients aux SBM. En ce qui concerne les caractéristiques fonctionnelles de l’innovation à savoir le risque perçu et la complexité d’usage, seul le risque s’est révélé être un véritable prédicteur de la résistance des clients bancaires. Les résultats révèlent par ailleurs que la communicabilité modère la relation entre la tradition et la résistance, le risque perçu et la résistance toutefois ne montrent aucune relation significative avec l’image. Des recommandations ont été formulées à l’endroit des managers des établissements bancaires afin de promouvoir l’utilisation de ces services.

description: Non-equilibrium path integral methods for computing quantum free energy differences are applied to a quantum particle trapped in a harmonic well of uniformly changing strength with the purpose of establishing the convergence properties of the work distribution and free energy as the number of degrees of freedom M in the regularized path integrals goes to infinity. The work distribution is found to converge when M tends to infinity regardless of the switching speed, leading to finite results for the free energy difference when the Jarzynski non-equilibrium work relation or the Crooks fluctuation relation are used. The nature of the convergence depends on the regularization method. For the Fourier method, the convergence of the free energy difference and work distribution go as 1/M, while both quantities converge as 1/M^2 when the bead regularization procedure is used. The implications of these results to more general systems are discussed.

description: The thermal and magnetic histories of planetesimals provide unique insights into the formation and evolution of Earth's building blocks. These histories can be gleaned from meteorites by using numerical models to translate measured properties into planetesimal behaviour. In this paper, we present a new 1D planetesimal thermal evolution and dynamo generation model. This magnetic field generation model is the first of a differentiated, mantled planetesimal that includes both mantle convection and non-eutectic core solidification. We have improved fundamental aspects of mantle heat transport by including a more detailed viscosity model and stagnant lid convection parametrisations consistent with internal heating. We have also added radiogenic heating from $^{60}Fe$ in the metallic Fe-FeS core. Additionally, we implement a combined thermal and compositional buoyancy flux, as well as the latest magnetic field scaling laws to predict magnetic field strengths during the planetesimal's thermal evolution until core solidification is complete. We illustrate the consequences of our model changes with an example run for a 500 km radius planetesimal. These effects include more rapid erosion of core thermal stratification and longer duration of mantle convection compared to previous studies. The additional buoyancy from core solidification has a marginal effect on dynamo strength, but for some initial core sulfur contents it can prevent cessation of the dynamo when mantle convection ends. Our model can be used to investigate the effects of individual parameters on dynamo generation and constrain properties of specific meteorite parent bodies. Combined, these updates mean this model can predict the most reliable and complete magnetic field history for a planetesimal to date, so is a valuable tool for deciphering planetesimal behaviour from meteorite properties.

description: The influence of a time-varying ram pressure on spiral galaxies in clusters is explored with a new simulation method based on the N-body SPH/tree code GADGET. We have adapted the code to describe the interaction of two different gas phases, the diffuse hot intracluster medium (ICM) and the denser and colder interstellar medium (ISM). Both the ICM and ISM components are introduced as SPH particles. As a galaxy arrives on a highly radial orbit from outskirts to cluster center, it crosses the ICM density peak and experiences a time-varying wind. Depending on the duration and intensity of the ISM-ICM interaction, early and late type galaxies in galaxy clusters with either a large or small ICM distribution are found to show different stripping efficiencies, amounts of reaccretion of the extra-planar ISM, and final masses. We compare the numerical results with analytical approximations of different complexity and indicate the limits of the Gunn & Gott simple stripping formula. Our investigations emphasize the role of the galactic orbital history to the stripping amount. We discuss the contribution of ram pressure stripping to the origin of the ICM and its metallicity. We propose gas accumulations like tails, filaments, or ripples to be responsible for stripping in regions with low overall ICM occurrence.

description: High-speed long-range quantum communication requires combining frequency multiplexed photonic channels with quantum memories. We experimentally demonstrate an integrated quantum frequency conversion protocol that can convert between wavelength division multiplexing channels in the telecom range with an efficiency of $55\pm 8\%$ and a noise subtracted HOM dip visibility of 84.5%. This protocol is based on a cascaded second order nonlinear interaction and can be used to interface a broad spectrum of frequencies with narrowband quantum memories, or alternatively as a quantum optical transponder, efficiently interfacing different regions of a frequency-multiplexed spectrum.

Revealing the Physical Conditions around Sgr A* using Bayesian Inference -- I. Observations and Radiative Transfer

description: We report sub-arcsecond ALMA observations between 272 - 375 GHz towards Sgr A*'s Circumnuclear disk (CND). Our data comprises 8 individual pointings, with significant SiO (8(7) - 7(6)) and SO (7 - 6) emission detected towards 98 positions within these pointings. Additionally, we identify H2CS (9(1,9) - 8(1,8)), OCS (25 - 24) and CH3OH (2(1,1) - 2(0,2)) towards a smaller subset of positions. By using the observed peak line flux density together with a Bayesian Inference technique informed by radiative transfer models, we systematically recover the physical gas conditions towards each of these positions. We estimate that the bulk of the surveyed gas has temperature T < 500 K and density n $\lessapprox 10^{6}$ cm$^{-3}$, consistent with previous studies of similar positions as traced by HCN clumps. However, we identify an uncharacteristically hot (T $\approx 600$ K) and dense (n $\approx 10^{6}$ cm$^{-3}$) source in the Northeastern Arm. This position is found to be approximately consistent with a gravitationally bound region dominated by turbulence. We also identify a nearby cold (T $\approx 60$ K) and extremely dense (n $\approx 10^{7}$ cm$^{-3}$) position that is again potentially bound and dominated by turbulence. We also determine that the total gas mass contained within the CND is M $\approx 4 \times 10^{4}$ $M_{\odot}$. Furthermore, we qualitatively note that the observed chemical enrichment across large scales within the CND is consistent with bulk grain processing, though multiple desorption mechanisms are plausibly responsible. Further chemical modelling is required to identify the physical origin of the grain-processing, as well as the localised H2CS and OCS emission.

description: Torque and magnetization measurements in magnetic fields $H$ up to 14 T were performed on CeCoIn$_5$ single crystals. The amplitude of the paramagnetic torque shows an $H^{2.3}$ dependence in the mixed state and an $H^{2}$ dependence in the normal state. In addition, the mixed-state magnetizations for both $H\parallel c$ and $H\parallel ab$ axes show anomalous behavior after the subtraction of the corresponding paramagnetic contributions as linear extrapolations of the normal-state magnetization. These experimental results point towards a nonlinear paramagnetic magnetization in the mixed state of CeCoIn$_5$, which is a result of the fact that both orbital and Pauli limiting effects dominate in the mixed state.

description: We present Chandra X-ray Observatory ACIS-S3 X-ray imaging observations and VLT/FORS2 and Hubble Space Telescope optical observations of two low-density Galactic globular clusters; NGC 6366 and M55. We detect 16 X-ray sources with 0.5-6.0 keV luminosities above Lx=4E30 erg/s within the half-mass radius of M55, of which 8 or 9 are expected to be background sources, and 5 within the half-mass radius of NGC 6366, of which 4 are expected to be background sources. Optical counterparts are identified for several X-ray sources in both clusters and from these we conclude that 3 of the X-ray sources in M55 and 2 or 3 of the X-ray sources in NGC 6366 are probably related to the cluster. Combining these results with those for other clusters, we find the best fit for a predicted number of X-ray sources in a globular cluster Nc=1.2 Gamma+1.1 Mh, where Gamma is the collision number and Mh is (half of) the cluster mass, both normalized to the values for the globular cluster M4. Some sources tentatively classified as magnetically active binaries are more luminous in X-rays than the upper limit of Lx~0.001Lbol of such binaries in the solar neighbourhood. Comparison with XMM and ROSAT observations lead us to conclude that the brightest X-ray source in M55, a dwarf nova, becomes fainter in X-rays during the optical outburst, in accordance with other dwarf novae. The brightest X-ray source in NGC 6366 is a point source surrounded by a slightly offset extended source. The absence of galaxies and Halpha emission in our optical observations argues against a cluster of galaxies and against a planetary nebula, and we suggest that the source may be an old nova.
