description: A small fluctuation of the photon beam position will affect the characteristics of the synchrotron radiation (SR) intensity and polarization when it enters the end-station through the related beamline. In this paper, by changing the electron orbit equilibrium position in the vertical direction, we have measured the corresponding changes in the absorption strength of the SR with a gold mesh in different chopper aperture positions. It is found that for three aperture positions, the absorption intensity of the gold mesh shows a good Gaussian distribution as the photon beam position moves, while the ratio of the SR intensity passing through the upper and lower apertures shows a monotonous variation. This suggests a new method for estimating the circular polarization degree of SR originating from the bending magnet based on our current measurement.

description: We describe a tool we improved to detect excess noise in the gravitational wave (GW) channel arising from its bilinear or nonlinear coupling with fluctuations of various components of a GW interferometer and its environment. We also describe a higher-order statistics tool we developed to characterize these couplings, e.g., by unraveling the frequencies of the fluctuations contributing to such noise, and demonstrate its utility by applying it to understand nonlinear couplings in Advanced LIGO engineering data. Once such noise is detected, it is highly desirable to remove it or correct for it. Such action in the past has been shown to improve the sensitivity of the instrument in searches of astrophysical signals. If this is not possible, then steps must be taken to mitigate its influence, e.g., by characterizing its effect on astrophysical searches. We illustrate this through a study of the effect of transient sine-Gaussian noise artifacts on a compact binary coalescence template bank.

description: Building on our previous spectroscopic and photometric analysis of the isolated Local Group dwarf irregular (dIrr) galaxy WLM, we present a comparison of the metallicities of its RGB stars with respect to the well studied Local Group dwarf spheroidal galaxies (dSphs) and Magellanic Clouds. We calculate a mean metallicity of [Fe/H]$ = -1.28 \pm 0.02$, and intrinsic spread in metallicity of $σ= 0.38 \pm 0.04$ dex, similar to the mean and spread observed in the massive dSph Fornax and the Small Magellanic Cloud. Thus, despite its isolated environment the global metallicity still follows expectations for WLM's mass and its global chemical evolution is similar to other nearby luminous dwarf galaxies (gas-rich or gas-poor). The data also show a radial gradient in [Fe/H] of $\rm{d[Fe/H]/dr_{c}} = -0.04 \pm 0.04$ dex $\rm{r_{c}^{-1}}$, which is flatter than that seen in the unbiased and spatially extended surveys of dSphs. Comparison of the spatial distribution of [Fe/H] in WLM, the Magellanic Clouds, and a sample of Local Group dSphs, shows an apparent dichotomy in the sense that the dIrrs have statistically flatter radial [Fe/H] gradients than the low angular momentum dSphs. The correlation between angular momentum and radial metallicity gradient is further supported when considering the Local Group dEs. This chemodynamic relationship offers a new and useful constraint for environment driven dwarf galaxy evolution models in the Local Group.

description: There are three categories of stars whose masses have been found accurately in recent times: (1) two for which Shapiro delay is used which is possible due to GR light bending as the partner is heavy : PSR J1614-2230 and PSR J1903+0327 (2) six eclipsing stars for which numerical Roche Lobe geometry is used and (3) 3 stars for which spectroscopic methods are used and in fact for these three the mass and radii both are estimated. Motivated by large color (N_c) expansion using a modified Richardson potential, along with density dependent quark masses thereby allowing chiral symmetry restoration, we get compact strange stars fitting all the observed masses.

Year: 2023

description: In this paper we investigate the effect of the implementation of convex-lifting-based robust control with approximated control law on a laboratory heat exchanger. The analyzed setup is the reference tracking problem of the heat exchanger output temperature. To analyze the efficiency of the approximated convex-lifting-based robust control, the tunable convex-lifting-based robust control, and the robust model predictive control were also implemented. The control performance was evaluated using the energy consumption and the corresponding carbon footprint emissions of the heat exchanger. The real-time computational complexity was evaluated based on the volume of the robust positive invariant set and the average time necessary to compute the value of the manipulated variable. The expected advantage of the robust control method is increased control performance and decreased computational complexity compared to the other designed robust controllers.

description: The quantum O(N) model in the infinite $N$ limit is a paradigm for symmetry-breaking. Qualitatively, its phase diagram is an excellent guide to the equilibrium physics for more realistic values of $N$ in varying spatial dimensions ($d>1$). Here we investigate the physics of this model out of equilibrium, specifically its response to global quenches starting in the disordered phase. If the model were to exhibit equilibration, the late time state could be inferred from the finite temperature phase diagram. In the infinite $N$ limit, we show that not only does the model not lead to equilibration on account of an infinite number of conserved quantities, it also does \emph{not} relax to a generalized Gibbs ensemble consistent with these conserved quantities. Nevertheless, we \emph{still} find that the late time states following quenches bear strong signatures of the equilibrium phase diagram. Notably, we find that the model exhibits coarsening to a non-equilibrium critical state only in dimensions $d>2$, that is, if the equilibrium phase diagram contains an ordered phase at non-zero temperatures.

description: The potential for blockchain technology to eliminate the middleman and replace the top down hierarchical model of governance with a system of distributed cooperation has opened up many new opportunities, as well as dilemmas. Surpassing the level of acceptance by early tech adopters, the market of smart contracts is now moving towards wider acceptance from regular (non tech) users. For this to happen however, smart contract development will have to overcome certain technical and legal obstacles to bring the code and the user closer. Guided by notions from contract law and consumer protection we highlight the information gap that exists between users, legal bodies and the source code. We present a spectrum of low-code to no-code initiatives that aim at bridging this gap, promising the potential of higher regulatory acceptance. Nevertheless, this highlights the so called "Pitfall of the Trustless Dream", because arguably solutions to the information gap tend to make the system more centralized. In this article, we aim to make a practical contribution of relevance to the wide-spread adoption of smart contracts and their legal acceptance by analyzing the evolving practices that bring the user and the code closer.

description: The crystallization of bundles in filament networks interacting via long-range repulsions in confinement is described by a phenomenological model. The model demonstrates the formation of the hexagonal crystalline order via the interplay of the confinement potential and the filament-filament repulsion. Two distinct crystallization mechanisms in the short- and large- screening length regimes are discussed, and the phase diagram is obtained. Simulation of large bundles predicts the existence of topological defects within the bundled filaments. This electrostatic repulsion-driven crystallization model arising from studying filament networks can even find a more general context extending to charged colloidal systems.

description: We present a determination of the charm-quark mass in the MSbar scheme using the data combination of charm production cross section measurements in deep-inelastic scattering at HERA. The framework of global analyses of the proton structure accounts for all correlations of the charm-quark mass with the other non-perturbative parameters, most importantly the gluon distribution function in the proton and the strong coupling constant alpha_s(M_Z). We obtain at next-to-leading order in QCD the value m_c(m_c) = 1.15 +- 0.04 (exp) +0.04/-0.00 (scale) GeV and at approximate next-to-next-to-leading order m_c(m_c) = 1.24 +- 0.03 (exp) +0.03/-0.02 (scale) +0.00/-0.07 (theory) GeV with an accuracy competitive with other methods.

description: We applied the social cognitive model of work satisfaction to the transition from lower secondary education to work in Switzerland and combined career decision and adjustment to work. The model assumes that self-efficacy affects career decision outcomes and adjustment after transition to work. Self-efficacy interacts with parental support during career decision making. We tested the model using a longitudinal sample of 603 adolescents who filled out questionnaires in seventh grade, ninth grade, and 1 year after starting work. Structural equation models showed that parental supportweakens the effect of self-efficacy on anticipated person–job fit and expectations of work conditions (moderation). Expectations of work conditions and a company’s support help newcomers to attain a high perceived person–job fit. These findings have several implications on how to support adolescents’ school-to-work transition.

description: Introduction: In hip fracture care, time to surgery (TTS) is a commonly used quality indicator associated with patient outcomes including mortality. This study aimed to identify patient and hospital-level characteristics associated with TTS in Ireland. Methods: National data from the Irish Hip Fracture Database (IHFD) (2016–2020) were analysed along with hospital-level characteristics obtained from a 2020 organisational survey. Generalised linear model regression was used to explore the association of TTS with case-mix, surgical details, hospital-level staffing and specific protocols recommended to expedite surgery. Results: A total of 14,951 patients with surgically treated hip fracture from 16 hospitals were included (Mean age= 80.6 years (SD=8.8), 70.4% female). Mean TTS was 40.9 h (SD=60.3 h). Case-mix factors associated with longer TTS were male sex and higher American Society of Anaesthesiologists (ASA) grade. Other factors found to be associated with longer TTS included low pre-morbid mobility, inter-hospital transfer, weekday presentation, pre-operative medical physician assessment, intracapsular fracture type, arthroplasty surgery, general anaesthesia, consultant grade of surgeon and lower hospital-level orthopaedic surgical capacity. The oldest age-group and pre-fracture nursing home residence were associated with shorter TTS when adjusted for other case-mix factors. None of four explored protocols for expediting surgery were associated with TTS. Conclusion: Patients with more comorbidity experience longer surgical delay after hip fracture in Ireland, in line with international research. Low availability of senior orthopaedic surgeons in Ireland may be delaying hip fracture surgery. Pathway of presentation, including via inter-hospital transfer or hospital bypass, is an important factor that requires further exploration. Further research is required to identify successful system-level protocols and interventions that may expedite hip fracture surgery within this setting.
Deriving ice thickness, glacier volume and bedrock morphology of the Austre Lovénbreen (Svalbard) using Ground-penetrating Radar

description: The Austre Lovénbreen is a 4.6 km2 glacier on the Archipelago of Svalbard (79 degrees N) that has been surveyed over the last 47 years in order of monitoring in particular the glacier evolution and associated hydrological phenomena in the context of nowadays global warming. A three-week field survey over April 2010 allowed for the acquisition of a dense mesh of Ground-penetrating Radar (GPR) data with an average of 14683 points per km2 (67542 points total) on the glacier surface. The profiles were acquired using a Mala equipment with 100 MHz antennas, towed slowly enough to record on average every 0.3 m, a trace long enough to sound down to 189 m of ice. One profile was repeated with 50 MHz antenna to improve electromagnetic wave propagation depth in scattering media observed in the cirques closest to the slopes. The GPR was coupled to a GPS system to position traces. Each profile has been manually edited using standard GPR data processing including migration, to pick the reflection arrival time from the ice-bedrock interface. Snow cover was evaluated through 42 snow drilling measurements regularly spaced to cover all the glacier. These data were acquired at the time of the GPR survey and subsequently spatially interpolated using ordinary kriging. Using a snow velocity of 0.22 m/ns, the snow thickness was converted to electromagnetic wave travel-times and subtracted from the picked travel-times to the ice-bedrock interface. The resulting travel-times were converted to ice thickness using a velocity of 0.17 m/ns. The velocity uncertainty is discussed from a common mid-point profile analysis. A total of 67542 georeferenced data points with GPR-derived ice thicknesses, in addition to a glacier boundary line derived from satellite images taken during summer, were interpolated over the entire glacier surface using kriging with a 10 m grid size. Some uncertainty analysis were carried on and we calculated an averaged ice thickness of 76 m and a maximum depth of 164 m with a relative error of 11.9%. The volume of the glacier is derived as 0.3487$\pm$0.041 km3. Finally a 10-m grid map of the bedrock topography was derived by subtracting the ice thicknesses from a dual-frequency GPS-derived digital elevation model of the surface. These two datasets are the first step for modelling thermal evolution of the glacier and its bedrock, as well as the main hydrological network.

description: In the months since the publication of the first results, the noise performance of LISA Pathfinder has improved because of reduced Brownian noise due to the continued decrease in pressure around the test masses, from a better correction of noninertial effects, and from a better calibration of the electrostatic force actuation. In addition, the availability of numerous long noise measurement runs, during which no perturbation is purposely applied to the test masses, has allowed the measurement of noise with good statistics down to 20 mu Hz. The Letter presents the measured differential acceleration noise figure, which is at (1.74 +/- 0.01) fm s(-2)/root Hz above 2 mHz and (6 +/- 1) x 10 fm s(-2)/root Hz at 20 mu Hz, and discusses the physical sources for the measured noise. This performance provides an experimental benchmark demonstrating the ability to realize the low-frequency science potential of the LISA mission, recently selected by the European Space Agency.

description: Bloch oscillations, the oscillatory motion of a quantum particle in a periodic potential, are one of the most fascinating effects of coherent quantum transport. Originally studied in the context of electrons in crystals, Bloch oscillations manifest the wave nature of matter and are found in a wide variety of different physical systems. Here we report on the first experimental observation of fractional Bloch oscillations, using a photonic lattice as a model system of a two-particle extended Bose-Hubbard Hamiltonian. In our photonic simulator, the dynamics of two correlated particles hopping on a one-dimensional lattice is mapped into the motion of a single particle in a two-dimensional lattice with engineered defects and mimicked by light transport in a square waveguide lattice with a bent axis.

description: Dynamic spectrum access systems typically require information about the spectrum occupancy and thus the presence of other users in order to make a spectrum al-location decision for a new device. Simple methods of spectrum occupancy detection are often far from reliable, hence spectrum occupancy detection algorithms supported by machine learning or artificial intelligence are often and successfully used. To protect the privacy of user data and to reduce the amount of control data, an interesting approach is to use federated machine learning. This paper compares two approaches to system design using federated machine learning: with and without a central node.

description: In the present study the Li diffusivity in nanostructured samples of two glass forming model systems, spodumene (LiAlSi2O6) and lithium metaborate (LiBO2), was examined using 7Li nuclear magnetic resonance (NMR) spin-lattice relaxometry and dc conductivity measurements. The nanostructured samples were prepared by high-energy ball milling of the respective crystalline starting material on the one hand and the corresponding glass on the other hand. The diffusivity of the glass exceeds that of the crystalline sample for both systems. However, when the crystalline samples are mechanically treated by ball milling the diffusivity is enhanced. Nevertheless, the diffusivity of these nanocrystalline samples remains lower than that of the corresponding glass. Surprisingly, when the glassy samples are treated in the same way the diffusivity decreases. After sufficiently long milling times the diffusivity of these nanoglassy samples approaches that of the nanocrystalline samples. This convergence effect seems to be due to structural relaxation processes as is suggested by supplementary infrared spectroscopy and 27Al, 12B magic angle spinning NMR measurements. © by Oldenbourg Wissenschaftsverlag

description: In South Korea, the Soyang Lake is an important source of drinking water to the metropolitan areas including Seoul. However, water quality problems in the Soyang Lake have still remained due to chemical contaminations attributed to conventional farming practices in the upstream areas. Based on a downstream consumer survey using a contingent valuation method, this study estimated the expected willingness to pays (WTPs) for water quality improvement through the conversion to environmentally friendly farming (EFF). The results showed that the estimated annual mean WTP is KRW 36,115 per household. The aggregated WTPs of downstream respondents in the Soyang Lake are sufficient to compensate for the income losses of upstream EFF farmers in highland farming areas. In addition, we found that the downstream citizens who recognize the label for EFF products and who intend to purchase EFF products in the future have a significant impact on WTPs for water quality improvement.

description: Understanding and predicting movement is critical for conservation planning and disease risk mitigation, and important environmental drivers of animal movement have received extensive attention in the ecological literature. Social factors surrounding group fission and fusion events also directly affect movement. However, these events are infrequently measured in the wild and rarely linked to underlying mechanisms such as relatedness, agreement in reproductive status, or shared life stage. While some social factors cannot be directly observed in the field, individual animals congregating in groups and moving about a landscape can. In animal societies, groups may merge together in a fusion event, and a group may split in a fission event. These events, repeating over time within a population, constitute fission-fusion dynamics. Here, we study group structure and how individuals navigate the social environment that structure imposes, using a long-term, individual-level dataset on female bighorn sheep gathered at the Confederated Salish and Kootenai Tribal (CSKT) Bison Range in Montana, USA. In Chapter 2, we describe three dimensions of fission-fusion dynamics that clarify the context that informs an individual’s social environment: group size, composition, and spatial cohesion in this population. In Chapter 3, we relate these group attributes from the previous chapter to social processes and underlying drivers using a discrete choice model. Our analysis opens a door for understanding how social mechanisms precipitate observed space use behaviors, with implications for how we view animal societies in research. We find that general group-level attributes like group size and demographic makeup along with specific, dyadic social attributes like mother and cohort relationships each influence bighorn sheep group configurations at the Bison Range and drive fission and fusion events.

description: Cancer affects about 1 in 1000 pregnancies, which is estimated to account for approximately 5000 pregnancies in Europe each year. Despite affluent availability of clinical practice guidelines for cancer management in the course of pregnancy, there is very little ethical guidance consolidated for everyday use. Therefore, the aim of this work is to construct a framework, which would serve healthcare professionals as a reference tool when addressing ethical issues in cancer care during pregnancy. The framework is constructed around relational approach to respect for patient?s autonomy and ethics of care. It combines classical biomedical ethics principles and relational approaches to patient care. It emphasizes the importance of recognising the patient as another human being with her views on life, relationships and wishes, as well as forming a relationship between the patient and healthcare team, which is known as relational ethics. However, respect for individual autonomy is not discarded entirely. First and foremost, evidence-based information disclosure is essential to personalised patient care. The latter invites to integrate technical aspects of personalised medicine with relational approach to patient care. Furthermore, protection of the vulnerable also serves as a safeguard ensuring that patient is not compelled to choices that are not her own. Overall, this framework is expected to serve as a tool supporting ethical decision-making in cancer care during pregnancy. It can also be utilised by a variety of patient counselling services.

description: We present the DONUTS autoguiding algorithm, designed to fix stellar positions at the sub-pixel level for high-cadence time-series photometry, which is also capable of autoguiding on defocused stars. DONUTS was designed to calculate guide corrections from a series of science images and re-centre telescope pointing between each exposure. The algorithm has the unique ability of calculating guide corrections from under-sampled to heavily defocused point spread functions. We present the case for why such an algorithm is important for high precision photometry and give our results from off and on-sky testing. We discuss the limitations of DONUTS and the facilities where it soon will be deployed.

description: The study of the interaction potential between static charges within Monte-Carlo simulation of graphene is carried out. The numerical simulations are performed in the effective lattice field theory with noncompact $3 + 1$-dimensional Abelian lattice gauge fields and $2 + 1$-dimensional staggered lattice fermions. It is shown that for all considered temperatures the interaction can be well described by the Debye screened potential created by two-dimensional electron-hole excitations. At low temperatures Debye mass $m_D$ plays a role of order parameter of the insulator-semimetal phase transition. In the semimetal phase at high temperature graphene reveals the properties of weakly interacting two-dimensional plasma of fermions excitations.

description: Background: Most studies on biodegradable magnesium implants published recently use magnesium-calcium-alloys or magnesium-aluminum-rare earth-alloys. However, since rare earths are a mixture of elements and their toxicity is unclear, a reduced content of rare earths is favorable. The present study assesses the in vivo biocompatibility of two new magnesium alloys which have a reduced content (ZEK100) or contain no rare earths at all (AX30). Methods: 24 rabbits were randomized into 4 groups (AX30 or ZEK100, 3 or 6 months, respectively) and cylindrical pins were inserted in their tibiae. To assess the biodegradation μCT scans and histological examinations were performed. Results: The μCT scans showed that until month three ZEK100 degrades faster than AX30, but this difference is leveled out after 6 months. Histology revealed that both materials induce adverse host reactions and high numbers of osteoclasts in the recipient bone. The mineral apposition rates of both materials groups were high. Conclusions: Both alloys display favorable degradation characteristics, but they induce adverse host reactions, namely an osteoclast-driven resorption of bone and a subsequent periosteal formation of new bone. Therefore, the biocompatibility of ZEK100 and AX30 is questionable and further studies, which should focus on the interactions on cellular level, are needed.
SYNTHESIS, CHARACTERIZATION AND RIG TESTS OF SUPPORTED FE AND CO-BASED NANOSTRUCTURED CATALYSTS ACTIVE IN THE THERMOCHEMICAL BTL/CTL/GTL-FT PROCESSES

description: During this PhD project different Fe and Co-based catalysts active in the FT reaction have been synthesized, characterized and tested, in particular: 1- An impregnated synthesized Fe-based catalyst supported on SiO2 and promoted with K and Cu (30 %wt of Fe, 2 %wt of K and 3.75 %wt of Cu) named Fe30K2Cu3.75. In particular, potassium improves CO ad-sorption while Cu promotes the reduction of the iron oxides species. The loading of active metal and promoters have been already determined elsewhere in recent studies. 2- Three different Co-based catalysts synthesized by flame spray pyrolysis (FSP) and supported on SiO2, and eventually promoted with Ru (5 %wt of Co; 10 %wt of Co; 10 %wt of Co and 0.4 %wt of Ru). The catalysts are named as 5Co, 10Co and 10Co-0.4Ru. FSP technique allows to obtain single or mixed metal oxides characterized by a high surface area and high thermal stability due to the instantaneous dispersion, vaporization and flame-decomposition (pyrolysis) of an organic solution composed by the precursors of the catalyst. 3- Three different Fe-based samples supported on SiO2 and promoted with K and Cu, prepared with the use of ultrasound (US) (10 %wt of Fe; 30 %wt of Fe; 30 %wt of Fe, 2 %wt of K and 3.75 %wt of Cu). Cata-lysts are named as Fe10US, Fe30US and Fe30K2Cu3.75US. In particular US allows to synthesize materials with better morphological properties with respect to traditional impregnated samples. Fe30K2Cu3.75 (1) sample is active for the FT conversion even if syngas with a H2/CO ratio similar to the ratio of bio-syngas (H2/CO= 1) is fed to the reactor. The catalyst presents a satisfactory stability as a function of TOS and selec-tivity toward the reaction products remains essentially unchanged at different syngas ratios at the same temperature tested. The developed kinetic model is in fully agreement with the ones fundable in the recent literature for iron-based catalysts tested in fixed bed FT reactor. 10Co and 10Co-0.4Ru (2) samples are active in the FT synthesis in the range of temperatures tested with a H2/CO= 2 syngas fed to the reactor. 5Co did not show any activity to FT reaction in the experimental condi-tion tested. 10Co sample showed a great stability in function of TOS at T= 250 �C, reactants conversion and selectivity towards the reaction products were stable for the whole duration of the durability test (TOS= 200 h). The addition of 0.4 %wt of Ru improved significantly catalyst activity in terms of reactant conversion. All the US synthesized samples (3) are suitable catalysts for the FT reaction at the different tested conditions and with a H2/CO ratio equal to 2. Both Fe10US and Fe30US catalysts showed excellent stability as a function of TOS at all the tested reaction temperatures. The sonochemically prepared catalysts showed good results in terms of selectivity toward the reaction products.
EVOLUTION OF WOLBACHIA SYMBIOSIS IN ARTHOPODS AND NEMATODES: INSIGTHS FROM PHYLOGENETICS AND COMPARATIVE GENOMICS
Creators: name: COMANDATORE, FRANCESCO

description: Wolbachia is a bacterium observed in relationship with a wide array of arthropod and nematode species. This is an obligate intracellular symbiont, maternally transferred through the host oocytes. In arthropods Wolbachia is able to manipulate reproduction, using multiple strategies to increase the fitness of infected females. In nematodes the bacterium has a fundamental, and not completely understood, role in larvae development. Wolbachia infects ~50% of all the arthropod species worldwide, and in some of them it can be considered the most important sex determination factor. In contrast, Wolbachia presence is much more limited in nematodes, being present in a limited number of filarial species. The taxonomic status within the Wolbachia genus is highly debated, with the current classification dividing all strains in 14 'supergroups'. During my Ph.D. I studied the evolution of the symbiotic relationship between Wolbachia and its arthropod and nematode hosts, using genomic approaches. Indeed, during the evolution of the Wolbachia-host relationship, genetic signs have been left in the Wolbachia genomes. I worked to identify these genomic signs and to evaluate them within an evolutionary frame, in order to obtain a better understanding of how the Wolbachia-host symbiosis evolved. The work here presented can be organized in three major sections: i) the sequencing and analysis of the genome of the filarial nematode Dirofilaria immitis and of its symbiotic Wolbachia strain, wDi; ii) the sequencing of the genome of Wolbachia endosymbiont of Litomosoides sigmodontis, and the phylogenomic reconstruction of the Wolbachia supergroups A-D; iii) a comparison of the genomes of 26 Wolbachia strains spanning the A to F supergroups. Here a schematic summary of the results is reported: 1. Dirofilaria immitis and the Wolbachia symbiont wDi show metabolic complementarity for fundamental pathways 2. The metabolic pathway for the synthesis of wDi membrane proteins is one evolving the fastest in the genome of the bacterium 3. Nematode Wolbachia belonging to supergroups C and D are monophyletic, indicating that a single transition to mutualism likely occurred during the evolution of Wolbachia 4. Wolbachia strains of the C supergroup show genomic features that are unique in the genus, such as a much higher level of synteny compared to the rest of Wolbachia supergroups, and a newly generated pattern of GC skew curves, typically observed in free-living bacteria genomes 5. Wolbachia supergroups show conserved genomic features, which suggest genomic isolation among them.
