Abstract
By using the worldline Monte Carlo technique, matrix product state, and a variational approach à la Feynman, we investigate the equilibrium properties and relaxation features of the dissipative quantum Rabi model, where a two level system is coupled to a linear harmonic oscillator embedded in a viscous fluid. We show that, in the Ohmic regime, a Beretzinski-Kosterlitz-Thouless quantum phase transition occurs by varying the coupling strength between the two level system and the oscillator. This is a nonperturbative result, occurring even for extremely low dissipation magnitude. By using state-of-the-art theoretical methods, we unveil the features of the relaxation towards the thermodynamic equilibrium, pointing out the signatures of quantum phase transition both in the time and frequency domains. We prove that, for low and moderate values of the dissipation, the quantum phase transition occurs in the deep strong coupling regime. We propose to realize this model by coupling a flux qubit and a damped LC oscillator.

Abstract
Dark matter elastic scattering off nuclei can result in the excitation and ionization of the recoiling atom through the so-called Migdal effect. The energy deposition from the ionization electron adds to the energy deposited by the recoiling nuclear system and allows for the detection of interactions of sub-GeV/c^{2} mass dark matter. We present new constraints for sub-GeV/c^{2} dark matter using the dual-phase liquid argon time projection chamber of the DarkSide-50 experiment with an exposure of (12 306±184) kg d. The analysis is based on the ionization signal alone and significantly enhances the sensitivity of DarkSide-50, enabling sensitivity to dark matter with masses down to 40 MeV/c^{2}. Furthermore, it sets the most stringent upper limit on the spin independent dark matter nucleon cross section for masses below 3.6 GeV/c^{2}.

Abstract
We present a search for dark matter particles with sub-GeV/c^{2} masses whose interactions have final state electrons using the DarkSide-50 experiment's (12 306±184) kg d low-radioactivity liquid argon exposure. By analyzing the ionization signals, we exclude new parameter space for the dark matter-electron cross section σ[over ¯]_{e}, the axioelectric coupling constant g_{Ae}, and the dark photon kinetic mixing parameter κ. We also set the first dark matter direct-detection constraints on the mixing angle |U_{e4}|^{2} for keV/c^{2} sterile neutrinos.

Abstract
While the world's economies avoid the COVID-19 pandemic blockade, there is an urgent need for technologies aimed at reducing the transmission of COVID-19 in confined spaces such as hospital environments. Although the cleaning and disinfection procedures now have rather complex and sophisticated weapons, they do not seem to be sufficient to continuously maintain low levels of environmental microbiological contamination. This result can now be achieved through the cross-use, in space and time, of improved, more efficient and effective technologies. This result can now be achieved through the cross-use, in space and time, of improved technologies. This work highlights the possibility of crossing and cooperation of different disinfection techniques, such as to keep the microbial and viral load low over time.

Abstract
Abstract
Issue
Many diseases show differences in incidence, symptoms, and severity between men and women, combined with a different response to therapies. There are some international experiences of health policies about Gender Medicine, but the practical realizations are few and, for the female sex, usually focused only on fertile age.
Description of the problem
A Milan hospital (ASST Fatebenefratelli Sacco) decided to dedicate one of its sites, with gynecological and pediatric vocation but also with an Internal Medicine Unit in within, entirely to women's health. The focus of this site is a holistic approach to women's health needs, both physiologic and pathologic. Realized without additional institutional funds, this project was designed between June and October 2019, started in December 2019 and is still ongoing.
Results
One of the first actions taken was to admit only women in the Internal Medicine Unit. The Unit is now entirely focused on dealing with most frequent female pathologies, in particular on autoimmune, vascular, endocrinology and nephrology conditions. The Mental Health Unit, already specialized in supporting pregnancy and new mothers, is going to activate a “Mother-Baby Unit” to support potential hospitalization issues. Among its major aims, the Occupational Medicine Unit supports female workers in managing maternity leave. New outpatient clinical paths have been planned to strengthen key moments of women's life: developmental age, fertile age, menopause, and senescence. Based on multi-professional teams, these programs are targeted toward age-specific needs and combine knowledge of disease epidemiology with sociological needs. To better face emerging issues, a path is activated for each area every month.
Conclusions
The birth of the first Italian hospital entirely dedicated to Gender Medicine allows care of women's health on a holistic perspective. This is, indeed, a key step in the general appraisal of Gender Medicine at the national and international levels.
Key messages
A gender hospital with a holistic approach to women’s health needs, both physiologic and pathologic, was borne in Milan. Integrated clinical paths have been activated to assist women in the key moments of their life (developmental age, fertile age, menopause, and senescence).

Abstract
Spontaneous rectus sheath hematoma (SRSH) is an uncommon cause of acute abdominal pain characterized by bleeding within the rectus sheath; it is a benign condition and, in most cases, it is treated conservatively. Bleeding of the abdominal wall is an unusual condition that is quite challenging to identify promptly and can be easily overlooked during a routine physical examination. In daily practice, anticoagulant therapy is one of the main risk factors for hemorrhagic events. In this respect, we report a rare case of spontaneous hematoma of the abdominal wall (diagnosed and monitored through an ultrasound examination) that arose after sneezing in a patient receiving anticoagulant treatment.

Abstract
In condensed matter physics many features can be understood in terms of their topological properties. Here we report evidence of a topological quantum transition driven by the charge-phonon coupling in the spinless Haldane model on a honeycomb lattice, a well-known prototypical model of the Chern insulator. Starting from parameters describing the topological phase in the bare Haldane model, we show that increasing the strength of the charge lattice coupling drives the system towards a trivial insulator. The average number of fermions in the Dirac point, characterized by the lowest gap, exhibits a finite discontinuity at the transition point and can be used as a direct indicator of the topological quantum transition. Numerical simulations show, also, that the renormalized phonon propagator exhibits a two peak structure across the quantum transition, whereas, in the absence of the mass term in the bare Haldane model, there is indication of a complete softening of the effective vibrational mode, signaling a charge density wave instability.

Abstract
Directional sensitivity to nuclear recoils could provide a smoking gun for a possible discovery of dark matter in the form of WIMPs. A hint of directional dependence of the response of a dual-phase liquid argon Time Projection Chamber was found in the SCENE experiment. Given the potential importance of such a capability in the frame work of dark matter searches, a new dedicated experiment, ReD (Recoil Directionality), was designed in the framework of the DarkSide Collaboration, in order to scrutinize this hint. This contribution will describe the performance of the detectors achieved during the first test-beam, the current status of ReD and the perspectives for physics measurements during the forthcoming beam-time.

Abstract
We present new constraints on sub-GeV dark-matter particles scattering off electrons based on 6780.0 kg d of data collected with the DarkSide-50 dual-phase argon time projection chamber. This analysis uses electroluminescence signals due to ionized electrons extracted from the liquid argon target. The detector has a very high trigger probability for these signals, allowing for an analysis threshold of three extracted electrons, or approximately 0.05 keVee. We calculate the expected recoil spectra for dark matter-electron scattering in argon and, under the assumption of momentum-independent scattering, improve upon existing limits from XENON10 for dark-matter particles with masses between 30 and 100 MeV/c^{2}.

Abstract
We present the results of a search for dark matter weakly interacting massive particles (WIMPs) in the mass range below 20 GeV/c^{2} using a target of low-radioactivity argon with a 6786.0 kg d exposure. The data were obtained using the DarkSide-50 apparatus at Laboratori Nazionali del Gran Sasso. The analysis is based on the ionization signal, for which the DarkSide-50 time projection chamber is fully efficient at 0.1 keVee. The observed rate in the detector at 0.5 keVee is about 1.5 event/keVee/kg/d and is almost entirely accounted for by known background sources. We obtain a 90% C.L. exclusion limit above 1.8 GeV/c^{2} for the spin-independent cross section of dark matter WIMPs on nucleons, extending the exclusion region for dark matter below previous limits in the range 1.8-6 GeV/c^{2}.

Abstract
Second-order continuous phase transitions are characterized by symmetry breaking with order parameters. Topological orders of electrons, characterized by the topological index defined in momentum space, provide a distinct perspective for phase transitions, which are categorized as quantum phase transitions not being accompanied by symmetry breaking. However, there are still limited observations of counterparts in real space. Here we show a real-space topological phase transition in a chiral magnet MnGe, hosting a periodic array of hedgehog and antihedgehog topological spin singularities. This transition is driven by the pair annihilation of the hedgehogs and antihedgehogs acting as monopoles and antimonopoles of the emergent electromagnetic field. Observed anomalies in the magnetoresistivity and phonon softening are consistent with the theoretical prediction of critical phenomena associated with enhanced fluctuations of emergent field near the transition. This finding reveals a vital role of topology of the spins in strongly correlated systems. Phase transitions in topologically non-trivial systems are characterized by changes of topological invariants, rather than conventional order parameters. Here, the authors propose a real-space topological phase transition upon pair annihilation of emergent monopoles inherent in chiral magnet MnGe.

Abstract
We present the first unbiased results for the mobility μ of a one-dimensional Holstein polaron obtained by numerical analytic continuation combined with diagrammatic and worldline Monte Carlo methods in the thermodynamic limit. We have identified for the first time several distinct regimes in the λ-T plane including a band conduction region, incoherent metallic region, an activated hopping region, and a high-temperature saturation region. We observe that although mobilities and mean free paths at different values of λ differ by many orders of magnitude at small temperatures, their values at T larger than the bandwidth become very close to each other.

Abstract
The transport properties at finite temperature of crystalline organic semiconductors are investigated, within the Su-Schrieffer-Heeger model, by combining an exact diagonalization technique, Monte Carlo approaches, and a maximum entropy method. The temperature-dependent mobility data measured in single crystals of rubrene are successfully reproduced: a crossover from super- to subdiffusive motion occurs in the range 150≤T≤200 K, where the mean free path becomes of the order of the lattice parameter and strong memory effects start to appear. We provide an effective model, which can successfully explain features of the absorption spectra at low frequencies. The observed response to slowly varying electric field is interpreted by means of a simple model where the interaction between the charge carrier and lattice polarization modes is simulated by a harmonic interaction between a fictitious particle and an electron embedded in a viscous fluid.

Abstract
The spectral response and physical features of the 2D Hubbard-Holstein model are calculated both in equilibrium at zero and low chemical dopings, and after an ultrashort powerful light pulse, in undoped systems. At equilibrium and at strong charge-lattice couplings, the optical conductivity reveals a three-peak structure in agreement with experimental observations. After an ultrashort pulse and at nonzero electron-phonon interaction, phonon and spin subsystems oscillate with the phonon period T(ph)≈80 fs. The decay time of the phonon oscillations is about 150-200 fs, similar to the relaxation time of the charge system. We propose a criterion for observing these oscillations in high T(c) compounds: the time span of the pump light pulse τ(pump) has to be shorter than the phonon oscillation period T(ph).

Abstract
Nanomaterials engineered as nanotubes, quantum-dots, dendrimers or hybrid systems are increasing themselves by an annual mean rate of 4-5%, with rapid spread in various sectors e.g. biomedical. The liposolubility through membranes and the hydrosolubility through active transport do not interfere with nanoparticles below a certain size, which without activation processes and carrier, transport through thanks to capillaries, to intracellular pores (60 - 70 nm) and fissures (4 - 6 nm) in the same membranes. Conversely, in the processes of pinocytosis/endocytosis energy and carrier are required and endocytosis clathrin/caveolae mediated,is respectively for nanoparticles higher or lower than 200 nm. In occupational hazard nanostructures ranging from a few nm up to 100 - 150 nm have the ability to affect several organs through inhalation, intestinal, parental or dermal route of access. New toxicological aspects are associated to the capacity of nanomaterials of being more or less biocompatible or hydrosoluble, of creating bonds with proteins or to determine accumulation in the cells due to an incomplete elimination process.

Abstract
OBJECTIVES The aim of this study was to compare the intraindividual effects of contrast material with two different iodine concentrations on the conspicuity of hepatocellular carcinoma (HCC) and vascular and hepatic contrast enhancement during multiphasic, 64-section multidetector row CT (MDCT) in patients with cirrhosis using two contrast medium injection techniques. METHODS Patients were randomly assigned to one of two groups with an equal iodine dose but different contrast material injection techniques: scheme A, fixed injection duration (25 s), and scheme B, fixed injection flow rate (4 ml s(-1)). For each group, patients were randomised to receive both moderate-concentration contrast medium (MCCM) and high-concentration contrast medium (HCCM) during two CT examinations within 3 months. Enhancement of the aorta, liver and portal vein and the tumour-to-liver contrast-to-noise ratio (CNR) were compared between MCCM and HCCM. RESULTS 30 patients (mean age 59 years; range 45-80 years; 16 patients in scheme A and 14 in scheme B) with a total of 31 confirmed HCC nodules were prospectively enrolled. For scheme B, the mean contrast enhancement of the aorta and tumour-to-liver CNR were significantly higher with HCCM than with MCCM during the hepatic arterial phase (+350.5 HU vs +301.1 HU, p = 0.001, and +7.5 HU vs +5.5 HU, p = 0.004). For both groups, there was no significant difference between MCCM and HCCM for all other comparisons. CONCLUSION For a constant injection flow rate, HCCM significantly improves the conspicuity of HCC lesions and aortic enhancement during the hepatic arterial phase on 64-section MDCT in patients with cirrhosis.

Abstract
We study a single polaron in the Su-Schrieffer-Heeger (SSH) model using four different techniques (three numerical and one analytical). Polarons show a smooth crossover from weak to strong coupling, as a function of the electron-phonon coupling strength λ, in all models where this coupling depends only on phonon momentum q. In the SSH model the coupling also depends on the electron momentum k; we find it has a sharp transition, at a critical coupling strength λ(c), between states with zero and nonzero momentum of the ground state. All other properties of the polaron are also singular at λ=λ(c). This result is representative of all polarons with coupling depending on k and q, and will have important experimental consequences (e.g., in angle-resolved photoemission spectroscopy and conductivity experiments).

Abstract
The stability of striped magnetic phases in films of La(1-x)A(x)MnO(3) perovskites is investigated. A variational analysis is developed for different film thicknesses at fixed hole density (x = 0.3) and the competition among magnetic phases as a function of the transfer integral and the temperature is analyzed. The stabilization of an in-plane striped magnetic phase is observed with reducing the film thickness at low temperatures below the metal-insulator transition temperature. Within the adopted variational scheme, treating perturbatively the residual electron-phonon interaction, the dependence of the in-plane resistivity on temperature for different thicknesses is calculated. At low temperatures, due to the striped magnetic phase, the resistivity shows an important in-plane anisotropy. The obtained results are found to be consistent with experiments.

Abstract
The charge dynamics in weakly hole doped high temperature superconductors is studied in terms of the accurate numerical solution to a model of a single hole interacting with a quantum lattice in an antiferromagnetic background, and accurate far-infrared ellipsometry measurements. The experimentally observed two electronic bands in the infrared spectrum can be identified in terms of the interplay between the electron correlation and electron-phonon interaction resolving the long standing mystery of the midinfrared band.

Abstract
We develop a novel self-consistent approach for studying the angle resolved photoemission spectra (ARPES) of a hole in the t-J Holstein model giving perfect agreement with numerically exact diagrammatic Monte Carlo (DMC) data at zero temperature for all regimes of electron-phonon coupling. Generalizing the approach to finite temperatures, we find that the anomalous temperature dependence of the ARPES in undoped cuprates is explained by cooperative interplay of coupling of the hole to magnetic fluctuations and strong electron-phonon interaction.

Abstract
The nonlocal nature of the polaron formation in t - t '- t'' - J model is studied in large lattices up to 64 sites by developing a new numerical method. We show that the effect of longer-range hoppings t' and t'' is a large anisotropy of the electron-phonon interaction (EPI) leading to a completely different influence of EPI on the nodal and antinodal points in agreement with the experiments. Furthermore, nonlocal EPI preserves polaron's quantum motion, which destroys the antiferromagnetic order effectively, even in the strong coupling regime, although the quasiparticle weight in angle-resolved-photoemission spectroscopy is strongly suppressed.

Abstract
UNLABELLED Scientific research on rheumatic diseases was often focused on the link between psychological features and disease. Depression and anxiety are frequently observed with an higher incidence among rheumatic patients in comparison to general population. In autoimmune diseases, such as rheumatoid arthritis, an important role for psychiatric symptoms could be played by the alteration of cytokines levels. In the chronic-degenerative diseases, psychological factors such as stress and depression, can be involved in perception of pain. OBJECTIVE We aimed at evaluating in a sample of 50 patients (25 with rheumatoid arthritis and 25 with osteoarthritis) levels of pain, anxiety and depression. METHODS We evaluated two group of patients with rheumatic disease, group A (25 with Rheumatoid Arthritis, mean age = 45.1; DS =15.24) and group B (25 with osteoarthritis, mean age = 54.3; DS =14.74) by clinic examination and with the following tests, SF-MPQ, HAQ, HAM-A, HAM-D. RESULTS We found in group A higher levels of depression and anxiety but lower levels of pain, which was more expressed in group B. CONCLUSION Depression and anxiety were observed with an higher prevalence in patients with autoimmune disease, whereas pain was stronger in patients with osteoarthritis, a degenerative disease. We could explain this phenomenon considering the aetiopathology of the two conditions. As regard to autoimmune disorders, these symptoms may reflect the direct effect of cytokines on the central nervous system. As far as it concerns chronic-degenerative diseases, anxiety and depression are usually considered "reactive" to pain, not "constitutive".

Abstract
The optical absorption of the Fröhlich polaron model is obtained by an approximation-free diagrammatic Monte Carlo method and compared with two new approximate approaches that treat lattice relaxation effects in different ways. We show that: (i) a strong coupling expansion, based on the Franck-Condon principle, well describes the optical conductivity for large coupling strengths (alpha > 10); (ii) a memory function formalism with phonon broadened levels reproduces the optical response for weak coupling strengths (alpha < 6) taking the dynamic lattice relaxation into account. In the coupling regime 6 < alpha < 10, the optical conductivity is a rapidly changing superposition of both Franck-Condon and dynamic contributions.

Abstract
This double-blind, randomized, placebo-controlled study investigated the therapeutic effects of a single dose of doxofylline, a methylxanthine derivative, in 10 patients aged 26-79 years. All patients had acute exacerbation of chronic obstructive airways disease partially reversible with salbutamol inhaler. Doxofylline was administered intravenously at a dose of 200 mg over 15 min on two different occasions separated by at least 24 h. Doxofylline increased forced expiratory volume in the first second of expiration compared with baseline as follows: +20% after 2 h (P less than 0.01); +31% after 4 h (P less than 0.01); and +13% after 6 h (NS). Changes produced by placebo at these times were -4.4%, -14% and -5% (all NS). The average differences between the groups were significant at all observation times. At the end of the observation period eight out of 10 patients given doxofylline and one out of 10 patients given placebo had improved clinically according to the patients' own opinion. Clinical tolerability of doxofylline proved to be good since no signs of local or general side-effects were observed in any of the patients treated.
