description: The incidence and the risk factors of in-hospitalized acute kidney injury (AKI) in patients hospitalized for atrial fibrillation (AF) were unclear. The Improving Care for Cardiovascular Disease in China-AF (CCC-AF) project is an ongoing registry and quality improvement project, with 240 hospitals recruited across China. We selected 4527 patients hospitalized for AF registered in the CCC-AF from January 2015 to January 2019. Patients were divided into the AKI and non-AKI groups according to the changes in serum creatinine levels during hospitalization. Among the 4527 patients, the incidence of AKI was 8.0% (361/4527). Multivariate logistic analysis results indicated that the incidence of in-hospital AKI in patients with AF on admission was 2.6 times higher than that in patients with sinus rhythm (OR 2.60, 95% CI 1.77–3.81). Age (per 10-year increase, OR 1.22, 95% CI 1.07–1.38), atrial flutter/atrial tachycardia on admission (OR 2.16, 95% CI 1.12–4.15), diuretics therapy before admission (OR 1.48, 95% CI 1.07–2.04) and baseline hemoglobin (per 20 g/L decrease, OR 1.21, 95% CI 1.10–1.32) were independent risk factors for in-hospital AKI. β blockers therapy given before admission (OR 0.67, 95% CI 0.51–0.87) and non-warfarin therapy during hospitalization (OR 0.71, 95% CI 0.53–0.96) were associated with a decreased risk of in-hospital AKI. After adjustment for confounders, in-hospital AKI was associated with a 34% increase in risk of major adverse cardiovascular (OR 1.34, 95% CI 1.02–1.90, p = 0.023). Clinicians should pay attention to the monitoring and prevention of in-hospital AKI to improve the prognosis of patients with AF.

description: Effects of pressure on the electronic structure, electron-phonon interaction, and superconductivity of the high entropy alloy (TaNb)$_{0.67}$(HfZrTi)$_{0.33}$ are studied in the pressure range 0 - 100 GPa. The electronic structure is calculated using the Korringa-Kohn-Rostoker method with the coherent potential approximation. Effects of pressure on the lattice dynamics are simulated using the Debye-Grüneisen model and the Grüneisen parameter at ambient conditions. In addition, the Debye temperature and Sommerfeld electronic heat capacity coefficient were experimentally determined. The electron-phonon coupling parameter $λ$ is calculated using the McMillan-Hopfield parameters and computed within the rigid muffin tin approximation. We find, that the system undergoes the Lifshitz transition, as one of the bands crosses the Fermi level at elevated pressures. The electron-phonon coupling parameter $λ$ decreases above 10 GPa. The calculated superconducting $T_c$ increases up to 40 - 50 GPa and, later, is stabilized at the larger value than for the ambient conditions, in agreement with the experimental findings. Our results show that the experimentally observed evolution of $T_c$ with pressure in (TaNb)$_{0.67}$(HfZrTi)$_{0.33}$ can be well explained by the classical electron-phonon mechanism.

description: A money-based model for the power law distribution (PLD) of wealth in an economically interacting population is introduced. The basic feature of our model is concentrating on the capital movements and avoiding the complexity of micro behaviors of individuals. It is proposed as an extension of the Equiluz and Zimmermann's (EZ) model for crowding and information transmission in financial markets. Still, we must emphasize that in EZ model the PLD without exponential correction is obtained only for a particular parameter, while our pattern will give it within a wide range. The Zipf exponent depends on the parameters in a nontrivial way and is exactly calculated in this paper.

description: This paper has estimated the demand and income elasticity for different fish types in Tripura and has projected the demand of fish. Three-stage multiple budgeting framework of household was structured in simple way mitigating the drawback of limited sample size and aggregation problem. The coefficient of food and fish expenditure functions for urban, rural and overall Tripura have been found to be positive and significant, indicating that the response of food expenditure to income changes and fish expenditure to food budget changes are substantial. All the coefficients of specific fish consumption (local carps, local non-carps, inter-state non-carps and small weed fish) have been found to be significant, except for the coefficient of inter-state carps (IC) consumption function. Looking at the variability of income elasticities across the Choiced Fish Groups (CFGs), all CFGs have substantial importance with respect to income change, except inter-state carps (IC) which is likely to have no relation with the change in income basket for the consumers. The income elasticity of demand for local carps in Tripura has been found highest among all the CFGs and is expected to play a dominating role in meeting fish demand. Demand for the fish under the baseline scenario (considering base year 2004) is likely to grow at an annual rate of 3.38 per cent for the state and at the rate of 3.95 per cent and 2.00 per cent for urban and rural areas, respectively between 2004 and 2015. The demand for fish by 2015 has been projected as 80,153 Mt shared by 62,910 Mt of carps (local and inter-state) and 17,243 Mt of non-carps. The demand for local carps has been projected to be nearly 50 percent (40,624 Mt) of total projected demand of fish in 2015.

description: Cardiovascular diseases are the main cause of treatment-related morbidity and mortality in childhood cancer patients. Anthracyclines, one of the most common chemotherapeutic agents in treatment regimens, are implicated in chemotherapy-induced cardiotoxicity. This review describes the pharmacogenomic markers related to anthracycline-induced cardiotoxicity affecting childhood cancer patients. We also included a brief overview of the applicability of reported findings to the well-established PETALE cohort of childhood acute lymphoblastic leukemia survivors of the Sainte-Justine University Health Center (Canada). The wide variation in interindividual susceptibility to anthracycline-induced cardiotoxicity, along with a multitude of genetic variants detected through association studies, suggests that genetic contributions could be essential for the design of new individualized preventive approaches.
New outburst from the luminous supersoft source SSS1 in NGC 300 with periodic modulation

description: The nearby galaxy NGC 300 is hosting two luminous transient supersoft X-ray sources with bolometric luminosities above 3x10^38 erg/s, assuming simple black-body spectra with temperatures around 60-70 eV. For one of these, SSS1, a periodic modulation of 5.4h was observed in an XMM-Newton observation from 1st of January 2001 lasting 47 ks, but not visible 6 days earlier when the luminosity was higher. We report here the detection of a new outburst from this source, which occurred during two more recent XMM-Newton observations performed on 17 to 20 December 2016 lasting for 310 ks. The luminosity was similar as in December 2000, and the 0.2-2.0 keV light curve revealed again a periodic modulation, with a period of 4.68+-0.26h, significant only in the first of the two observations. Taking into account the large uncertainties (the 2001 period was re-estimated at 5.7+-1.1h), the two values could be marginally compatible, and maybe associated with an orbital period, although the signal strength is highly variable. Thanks to the new long exposures, an additional absorption feature is now visible in the spectra, that we modelled with an absorption edge. This component decreases the bolometric luminosity below 3x10^38 erg/s and would therefore allow the presence of a white dwarf with a mass close to the Chandrasekhar limit. The system was found in outburst in 1992, 2000, 2008, and 2016 suggesting a possible recurrence period of about 8 years. We discuss viable models involving white dwarfs, neutron stars or black holes.

MgS in detached shells around carbon stars. Mining the mass-loss history

description: We investigate the dust composition of detached shells around carbon stars, with a focus to understand the origin of the cool magnesium-sulfide (MgS) material around warm carbon stars, which has been detected around several of these objects. We build a radiative transfer model of a carbon star surrounded by an expanding detached shell of dust. The shell contains amorphous carbon grains and MgS grains. We find that a small fraction of MgS dust (2% of the dust mass) can give a significant contribution to the IRAS 25 micron flux. However, the presence of MgS in the detached shell cannot be inferred from the IRAS broadband photometry alone but requires infrared spectroscopy. We apply the model to the detached-shell sources R Scl and U Cam, both exhibiting a cool MgS feature in their ISO/SWS spectra. We use the shell parameters derived for the molecular shell, using the CO submillimetre maps. The models, with MgS grains located in the detached shell, explain the MgS grain temperature, as derived from their ISO spectra, very well. This demonstrates that the MgS grains are located at the distance of the detached shell, which is a direct indication that these shells originate from a time when the stellar photosphere was already carbon-rich. In the case of R Scl, the IRAS photometry is simultaneously explained by the single shell model. In the case of U Cam, the IRAS photometry is under predicted, pointing to a contribution from cooler dust located even further away from the star than the molecular shell. We present a simple diagnostic to constrain the distance of the shell using the profile of the MgS emission feature. The emission feature shifts to longer wavelength with decreasing grain temperature. One can therefore infer a temperature and a corresponding distance to the star from the observed profile.

description: Fault-zone fluids control effective normal stress and fault strength. While most earthquake models assume a fixed pore fluid pressure distribution, geologists have documented fault valving behavior, that is, cyclic changes in pressure and unsteady fluid migration along faults. Here we quantify fault valving through 2-D antiplane shear simulations of earthquake sequences on a strike-slip fault with rate-and-state friction, upward Darcy flow along a permeable fault zone, and permeability evolution. Fluid overpressure develops during the interseismic period, when healing/sealing reduces fault permeability, and is released after earthquakes enhance permeability. Coupling between fluid flow, permeability and pressure evolution, and slip produces fluid-driven aseismic slip near the base of the seismogenic zone and earthquake swarms within the seismogenic zone, as ascending fluids pressurize and weaken the fault. This model might help explain observations of late interseismic fault unlocking, slow slip and creep transients, swarm seismicity, and rapid pressure/stress transmission in induced seismicity sequences.

description: The article examines the increasingly important role played by technology in the domain of public security in Germany, illustrating its effects on social life. In order to illuminate developments that govern the adoption of security technologies and render them in their dependencies comprehensible, we present two plausible and consistent future scenarios for Germany 2035. Following Jasanoff and Kim, these scenarios are theoretically conceived as two competing “sociotechnical imaginaries” which implies different trajectories for shaping the future. In these imaginaries, security technologies condition social change, and vice versa, in a mutually interdependent process. On the basis of current literature in tandem with a structured scenario development process, we condensed the present sociotechnical imaginaries into two tangible future scenarios for the field of public security, illustrating its effects on how we live as a society. Our overarching goal is to identify key factors that will mediate future developments, and, by extension, to facilitate discussion on the type of future we find collectively desirable. The analysis of impact factors resulted in ten key factors that play a crucial role for the use of security technologies and serve as a leverage for shaping the future. Projections of these factors lead to two narrative scenarios “To Be Ahead” and “Turn Back The Clock”.

description: We present optical and near-infrared follow-up observations of the X-Ray Flash (XRF) of July 23 2003. Our observations in the R-band cover the temporal range from 4.2 h to 64 days after the high energy event. We also present the results of multicolor imaging extending to the K-band on three epochs. The lightcurve of the R-band afterglow the first week after the burst is similar to the lightcurve for long duration Gamma-Ray Bursts (GRBs), i.e., a broken power-law with a late time slope of alpha=-2.0 (F_nu propto t^alpha). Furthermore, the spectral energy distribution (SED) has a power-law (F_nu propto nu^beta) shape with slope beta=-1.0. However, the decay slope at t<1 day is shallow, consistent with zero. This is in qualitative agreement with the prediction that XRFs are off-axis classical GRBs. After the first week there is a strong bump in the lightcurve, which peaks at around 16 days. The SED after the peak becomes significantly redder. We discuss the possible interpretations of this bump, and conclude that an underlying supernova is the most likely explanation since no other model appears consistent with the evolution of the SED. Finally, we present deep spectroscopy of the burst both in the afterglow and in the bump phase. A firm upper limit of z=2.3 is placed on the redshift of XRF030723 from the lack of Ly-alpha forest lines in the spectrum of the afterglow. The lack of significant absorption and emission lines in either of the two spectra excludes a spectroscopic redshift determination.

description: We have extracted the phase coherence time $τ_ϕ$ of electronic quasiparticles from the low field magnetoresistance of weakly disordered wires made of silver, copper and gold. In samples fabricated using our purest silver and gold sources, $τ_ϕ$ increases as $T^{-2/3}$ when the temperature $T$ is reduced, as predicted by the theory of electron-electron interactions in diffusive wires. In contrast, samples made of a silver source material of lesser purity or of copper exhibit an apparent saturation of $τ_ϕ$ starting between 0.1 and 1 K down to our base temperature of 40 mK. By implanting manganese impurities in silver wires, we show that even a minute concentration of magnetic impurities having a small Kondo temperature can lead to a quasi saturation of $τ_ϕ$ over a broad temperature range, while the resistance increase expected from the Kondo effect remains hidden by a large background. We also measured the conductance of Aharonov-Bohm rings fabricated using a very pure copper source and found that the amplitude of the $h/e$ conductance oscillations increases strongly with magnetic field. This set of experiments suggests that the frequently observed ``saturation'' of $τ_ϕ$ in weakly disordered metallic thin films can be attributed to spin-flip scattering from extremely dilute magnetic impurities, at a level undetectable by other means.

description: Serine palmitoyltransferase (SPT) plays the key role on catalysing the formation of 3-ketodihydrosphingosine, which is the first step of the de novo biosynthesis of sphingolipids. SPT is linked to many diseases including fungal infection, making it a potential therapeutic target. Thus, a logical docking-based virtual screening method was used to screen selective SPT inhibitor against fungi, not human. We used myriocin-similarity database to identify compounds with good binding with fungal SPT and poor binding with homology human SPT model. Preliminary bio-assay led to the discovery of a promising inhibitor WXP-003, which displayed good inhibitory activity against diversity fungi strains with MIC ranging from 0.78 to 12.5 μg/mL. WXP-003 could significantly reduce sphingolipids content in fungi and no effect on mouse fibroblast cell line L929. Molecular dynamics simulation depicted that SPT/WXP-003 complex formed the favoured interactions. Taken together, discovery of WXP-003 provided valuable guide for the development of novel anti-fungal agents.

Despite the amount of research focused on the Alpine orogen, different hypotheses still exist regarding varying seismicity distribution patterns throughout the numerous crustal blocks of different physical properties that comprise the region. The thermal field, also varying as a consequence of heterogeneous lithospheric properties, is a key controlling factor for rock strength via thermally activated creep and it exerts a first order influence on the depth of the brittle-ductile transition zone, the lower bound to the seismogenic zone and the spatial distribution of seismicity. Previous measurement constrained works across the orogen and its forelands that have defined the 3D lithospheric density distribution and thermal field facilitate the generation of an observation based rheological model of the region. Here we present rheological modelling results from across the Alps and their forelands and compare calculated strengths to observed seismicity patterns, in order to explain the localisation of deformation. The depth of peak seismic energy release in almost all regions was found to correlate to the calculated brittle-ductile transition, adding validity to the results achieved. We find a strong correlation between the lateral distribution of seismicity and the total strength of the lithosphere, occurring mainly in weaker zones, with crustal thickness and LAB depth highly influential.

description: We report a measurement of the spin polarisation of the recoiling neutron in deuterium photodisintegration, utilising a new large acceptance polarimeter within the Crystal Ball at MAMI. The measured photon energy range of 300~--~700~MeV provides the first measurement of recoil neutron polarisation at photon energies where the quark substructure of the deuteron plays a role, thereby providing important new constraints on photodisintegration mechanisms. A very high neutron polarisation in a narrow structure centred around $E_γ\sim$~570~MeV is observed, which is inconsistent with current theoretical predictions employing nucleon resonance degrees of freedom. A Legendre polynomial decomposition suggests this behaviour could be related to the excitation of the $d^*(2380)$ hexaquark.

description: The landscape configuration of socio-ecological land systems results from the interaction between the environmental conditions (relatively homogeneous within ecoregions) and country-level management and land-use decisions. However, social, land-use and sustainability research disciplines often study each independently. We used Euclidean distance analyses of five indicators of land systems functioning to explore the geographical patterns of across-border human-induced asymmetries in transnational ecoregions of South America. The most asymmetric transnational ecoregions occurred in the tropical rainforest biome which also showed the widest range of asymmetry values compared to other biomes. In contrast, transnational ecoregions in montane grasslands showed comparatively little asymmetries, and tropical dry forests showed intermediate asymmetry values. This pattern indicates that major asymmetries occur in land systems located in productive biomes with a comparatively recent history of development, whereas mature socio-ecosystems with a long history of human land use are more homogeneous across borders. In some cases, asymmetries may stabilize as a consequence of reinforcing feedbacks that promote contrasting land-use decisions across borders, including, for example, the establishment of protected areas, or the promotion of agro-industrial activities. Transnational socio-ecological land systems can be used to evaluate alternatives for sustainable development because they highlight the influence of institutions under different governance regimes in defining the spatial configuration and ecological properties of regions. We invite land-use and sustainability scientists to consider political border interactions as valuable “natural experiments” to better understand the interrelations between biophysical and political systems in defining planetary geographical-ecology in the Anthropocene.

title: Justifying ‘Justice’: Tracing the Cultural Politics of Punishment in the Wake of the 2011 English ‘Riots’
Creators: name: Peacock, Chloe
Publisher: name: Goldsmiths, University of London
Year: 2021

description: Taking the English ‘riots’ of August 2011 as a lens, this thesis explores how criminal justice professionals make sense of the punitive system within which they work. Though the four nights of unrest precipitated by the Metropolitan Police force’s killing of Mark Duggan in Tottenham have attracted a vast amount of sociological and criminological analysis, relatively little critical academic attention has been paid to the criminal justice reaction that followed. The thesis draws on qualitative interviews with prosecutors, sentencers, defence lawyers and policymakers who were responsible for designing and delivering the swift and strikingly severe response, characterised by extraordinarily harsh practices at each stage of the process. It applies a critical discourse analysis approach to professionals’ accounts, identifying the imaginations and narratives that allow them to variously rationalise, normalise and problematise this vindictive response to the disturbances. The thesis contends that agnosis, disavowal, denial and obfuscation are vital to justifying ‘justice’. The analysis shows how four interlocking and overlapping elements enable professionals to frame the punishment of rioters as proportionate, necessary and fair: forgetting England’s long history of unrest and ignoring or dismissing Duggan’s killing, distorting the demographics of ‘the rioters’, summoning a highly selective notion of public opinion, and obscuring the racialised and classed harms that prisons perpetuate. The thesis offers insight into the cultural politics of punishment in the contemporary conjuncture, highlighting the common sense ideas that sustain the criminal justice system from within. It suggests that a delimited, decontextualised and depoliticised notion of crime, racialised and classed discourses of criminality, an imagination of a monolithically punitive public, and strategic ignorance of the harms of punishment are integral to legitimising a violent and inherently racist and class-based system, both in the wake of the ‘riots’ and in their longer aftermath.

description: Purpose The purpose of this study was to correlate the gel strength of swollen matrix tablets with their in vitro robustness against agitation intensity and applied mechanical forces. Five commercial products, i.e. Glucophage®, Alfuzosin®, Tromphyllin®, Preductal® MR and Quetiapin® formulated as water-soluble/erodible matrix tablets were investigated. Methods Effect of agitation speed (50–150 rpm) on drug release, hydration/erosion and gel strength was investigated using USP paddle apparatus II. The gel strength of matrix tablets during dissolution at different conditions was characterized by a texture analyzer. Results Commercial tablets formulated with HPMC of higher viscosity, such as K15M or K100M, demonstrated the gel strength in swollen state >0.02 MPa. In this case, the release mechanism was predominantly diffusional and, therefore, not affected by stirring speed and mechanical stress. In contrast, the Quetiapin® matrix tablet, formulated with HPMC K 4 M in amount of approx. 25%, demonstrated the gel strength dropped below 0.02 MPa after 6 h of release. In this case, the drug was predominantly released via erosional mechanism and very susceptible to stirring speed. Conclusion Sufficient gel strength of swollen tablets is an important prerequisite for unchanged in vitro performance in consideration of mechanical stress.
Singularity-Free Inverse Dynamics for Underactuated Systems with a Rotating Mass

description: Motion control of underactuated systems through the inverse dynamics contains configuration singularities. These limitations in configuration space mainly stem from the inertial coupling that passive joints/bodies create. In this study, we present a model that is free from singularity while the trajectory of the rotating mass has a small-amplitude sine wave around its circle. First, we derive the modified non-linear dynamics for a rolling system. Also, the singularity regions for this underactuated system is demonstrated. Then, the wave parameters are designed under certain conditions to remove the coupling singularities. We obtain these conditions from the positive definiteness of the inertia matrix in the inverse dynamics. Finally, the simulation results are confirmed by using a prescribed Beta function on the specified states of the rolling carrier. Because our algebraic method is integrated into the non-linear dynamics, the proposed solution has a great potential to be extended to the Lagrangian mechanics with multiple degrees-of-freedom.

description: In this paper, we provide updated constraints on the bolometric quasar luminosity function (QLF) from $z=0$ to $z=7$. The constraints are based on an observational compilation that includes observations in the rest-frame IR, B band, UV, soft and hard X-ray in past decades. Our method follows Hopkins et al. 2007 with an updated quasar SED model and bolometric and extinction corrections. The new best-fit bolometric quasar luminosity function behaves qualitatively different from the Hopkins et al. 2007 model at high redshift. Compared with the old model, the number density normalization decreases towards higher redshift and the bright-end slope is steeper at $z\gtrsim 2$. Due to the paucity of measurements at the faint end, the faint end slope at $z\gtrsim 5$ is quite uncertain. We present two models, one featuring a progressively steeper faint-end slope at higher redshift and the other featuring a shallow faint-end slope at $z\gtrsim 5$. Further multi-band observations of the faint-end QLF are needed to distinguish between these models. The evolutionary pattern of the bolometric QLF can be interpreted as an early phase likely dominated by the hierarchical assembly of structures and a late phase likely dominated by the quenching of galaxies. We explore the implications of this model on the ionizing photon production by quasars, the CXB spectrum, the SMBH mass density and mass functions. The predicted hydrogen photoionization rate contributed by quasars is subdominant during the epoch of reionization and only becomes important at $z\lesssim 3$. The predicted CXB spectrum, cosmic SMBH mass density and SMBH mass function are generally consistent with existing observations.

 As an important component of natural science education, popular palaeontology education developed rapidly worldwide. Traditional offline public lectures, guide tours and peripheral products represent the main implementations. With the appearance of new technologies in recent years, new interactive teaching methods have emerged. Especially since the outbreak of COVID-19 at the end of 2019, traditional offline methods are temporarily shut down in China. Digital media technology-based new interactive online methods have started to play an irreplaceable role.

description: Context. The strong tidal dissipation in the couple Jupiter-Io is spread to all the moons involved in the Laplace resonance (Io, Europa, and Ganymede), leading to a migration of their orbits. Aims. We aim to characterize the future behavior of the Galilean satellites over the Solar System lifetime and to quantify the stability of the Laplace resonance. Since tidal dissipation makes possible the exit from the current resonances or capture into new ones, we investigate the capture of Callisto into resonance. Methods. We perform hundreds of propagations using an improved version of a recent semi-analytical model. As Ganymede moves outwards, it approaches the 2:1 resonance with Callisto, inducing a temporary chaotic motion in the system. For this reason, we draw a statistical picture of the outcome of the resonant encounter. Results. The system can settle into two distinct outcomes: A) a chain of three 2:1 two-body resonances (Io-Europa, Europa-Ganymede and Ganymede-Callisto), or B) a resonant chain involving the 2:1 two-body resonance Io-Europa plus at least one pure 4:2:1 three-body resonance, most frequently between Europa, Ganymede and Callisto. In case A (56\% of the simulations), the Laplace resonance is always preserved and the eccentricities remain confined to small values below 0.01. In case B (44\% of the simulations), the Laplace resonance is generally disrupted and the eccentricities of Ganymede and Callisto can increase up to about 0.1, making this configuration unstable and driving the system into new resonances. Conclusion. From our results, the capture of Callisto into resonance appears to be extremely likely (100\% of our simulations). Assuming the most recent estimate of the dissipation between Io and Jupiter, the resonant encounter happens at about 1.5 Gyrs from now. Therefore, the stability of the Laplace resonance is guaranteed at least up to about 1.5 Gyrs.

Discriminating between $CP$ and family transformations in the bilinear space of NHDM

description: The scalar potential of the N-Higgs-doublet model (NHDM) is best analyzed not in the space of N complex doublets $ϕ_a$ but in the $N^2$-dimensional space of real-valued bilinears constructed of $ϕ_a^\dagger ϕ_b$. In particular, many insights have been gained into CP violation in the 2HDM and 3HDM by studying how generalized CP transformations (GCPs) act in this bilinear space. These insights relied on the fact that GCPs, which involved an odd number of mirror reflection, could be clearly distinguished from Higgs family transformations by the sign of the determinant of the transformation matrix. It was recently pointed out that this criterion fails starting from 4HDM, where the reflection/rotation dichotomy does not exist anymore. In this paper, we restore intuition by finding a different quantity which faithfully discriminates between GCPs and Higgs family transformations in the bilinear space for any number of Higgs doublets. We also establish the necessary and sufficient conditions for an orthogonal transformation in the bilinear space to represent a viable transformation back in the space of N doublets, which is helpful if one prefers to build an NHDM directly in the bilinear space.

Self-consistent Green's function method for nuclei and nuclear matter

description: Recent results obtained by applying the method of self-consistent Green's functions to nuclei and nuclear matter are reviewed. Particular attention is given to the description of experimental data obtained from the (e,e'p) and (e,e'2N) reactions that determine one and two-nucleon removal probabilities in nuclei since the corresponding amplitudes are directly related to the imaginary parts of the single-particle and two-particle propagators. For this reason and the fact that these amplitudes can now be calculated with the inclusion of all the relevant physical processes, it is useful to explore the efficacy of the method of self-consistent Green's functions in describing these experimental data. Results for both finite nuclei and nuclear matter are discussed with particular emphasis on clarifying the role of short-range correlations in determining various experimental quantities. The important role of long-range correlations in determining the structure of low-energy correlations is also documented. For a complete understanding of nuclear phenomena it is therefore essential to include both types of physical correlations. We demonstrate that recent experimental results for these reactions combined with the reported theoretical calculations yield a very clear understanding of the properties of {\em all} protons in the nucleus. We propose that this knowledge of the properties of constituent fermions in a correlated many-body system is a unique feature of nuclear physics.
