description: Background. Coronavirus (COVID-19) contagion prevalence and the severity of its symptoms do not seem different for pregnant and postpartum women than the general population. Nevertheless, the possible traumatic experiences related to the spread of covid-19 show negative effects on women’s mental health during the childbearing and postnatal period. Although international reviews observed this phenomenon worldwide, an in-depth exploration of Italian pregnant and postpartum women’s wellbeing is needed, considering the specific phases of the virus spread and the restrictive measures imposed by Italian government throughout the last year. Aim. This research aims to identify and discuss existing studies on women’s antenatal and postnatal mental health during the first year of the pandemic in Italy. Method. In accordance with PRISMA guidelines, a systematic review was conducted, using the following databases: Web of Science, Embase, EBSCO (APA PsycArticles, APA PsycInfo; Psychology and Behavioral Sciences Collection; MEDLINE), Pubmed and other sources. Results. Eleven articles were included in the review and three meaning trajectories were identified: Pregnancy and postpartum continuum – from anxiety to depression and post-traumatic stress; Risk dimensions: previous psychopathologies and the lack of social support; Focus on others health before themselves. Conclusion. Findings suggest different vulnerable areas, such as a high fear for others health and the loss of the protective dimension of social support for pregnant and postpartum women’s wellbeing in Italy. This evidence might help to project useful and specific psychological screening and intervention programmes for perinatal clinic.

description: Background: The massive adoption of e-learning in academic education during the coronavirus disease (COVID-19) pandemic may be beneficial to digitally skilled individuals, such as Generation Z (Gen Z) members. However, some studies have underscored its negative psychological impact on the mental health of the young adults. We aimed to examine the psychological impact of prolonged e-learning on emotional adaptation among undergraduate students. A secondary objective was to identify key components for preventive interventions targeted toward the academic community by investigating the buffering effect of e-leaning on the impact of negative life events experienced during the pandemic. Methods: The participants were 529 Italian undergraduate students aged 18–26 years. We administered measures of personality traits, anxiety symptoms, peritraumatic dissociation, stress, and affinity for e-learning. This study examined emotional adaptation among Gen Z members who were subjected to prolonged academic e-learning during the 2nd COVID-19 lockdown in Italy. Results: Dysfunctional anxiety was not a major issue among our participants. This is indicative of the adoption of effective anxiety management skills during the pandemic. Nevertheless, the findings also underscored the vulnerability of the Gen Z population. Further, coronavirus anxiety significantly predicted mental health through the mediating effect of personality traits. Conclusions: Therefore, health care professionals should design and implement interventions and programmes that focus on coronavirus anxiety and psychological distress.

description: In this work we present for the first time an analytic framework for calculating the individual and joint distributions of the n-th most massive or n-th highest redshift galaxy cluster for a given survey characteristic allowing to formulate LCDM exclusion criteria. We show that the cumulative distribution functions steepen with increasing order, giving them a higher constraining power with respect to the extreme value statistics. Additionally, we find that the order statistics in mass (being dominated by clusters at lower redshifts) is sensitive to the matter density and the normalisation of the matter fluctuations, whereas the order statistics in redshift is particularly sensitive to the geometric evolution of the Universe. For a fixed cosmology, both order statistics are efficient probes of the functional shape of the mass function at the high mass end. To allow a quick assessment of both order statistics, we provide fits as a function of the survey area that allow percentile estimation with an accuracy better than two per cent. Furthermore, we discuss the joint distributions in the two-dimensional case for different combinations of order. Having introduced the theory, we apply the order statistical analysis to the SPT massive cluster sample and MCXC catalogue and find that the ten most massive clusters in the sample are consistent with LCDM and the Tinker mass function. In turn, by assuming the LCDM reference cosmology, order statistics can also be utilised for consistency checks of the completeness of the observed sample and of the modelling of the survey selection function.

description: Aim: The aim of the present study was to measure dental anxiety levels and oral health-related qualities of life (OHRQoL) in patients with periodontitis compared to healthy controls and to analyze their association with various demographic, clinical and periodontal parameters. Methods: Fifty-five patients with periodontitis and 56 healthy controls were enrolled. Collected data included demographics, smoking habits, numerical rating scale (NRS), Corah’s Dental Anxiety Scale (DAS) and Oral Health Impact Profile-14 (OHIP-14), DMFT index (Decayed, Missing and Filled Teeth), Plaque Index (PI), probing depth (PD), bleeding on probing (BOP), and radiographic bone loss. Results: Periodontitis patients exhibited statistically significant higher scores in the total DAS and in almost of single DAS domains. Compared to the control group, periodontitis patients exhibited worse OHIP-14 global as well as in all individual OHIP-14 domains scores. Among both periodontitis and control patients, the physical pain domain was where the highest impact was recorded, while the lowest impact was recorded in the functional limitation domain. Conclusion: Periodontitis patients were positively associated with higher levels of dental anxiety and worse OHRQoL. Self-perception of dental anxiety and OHRQoL should be regarded as an integral element in routine diagnostic work-up process of periodontal diseases. This study showed that for a nationally representative sample of the southern Italian population population, periodontal disease was significantly associated with the domains of OHRQoL.

description: We report a discovery of a proto-cluster in vigorous assembly and hosting strong star forming activities, associated to a radio galaxy USS 1558-003 at z=2.53, as traced by a wide-field narrow-band H_alpha imaging with MOIRCS on Subaru Telescope. We find 68 H_alpha emitters with dust-uncorrected SFRs down to 8.6 Msun/yr. Their spatial distribution indicates that there are three prominent clumps of H_alpha emitters, one surrounding the radio galaxy and another located at ~1.5 Mpc away to the south-west, and the other located in between the two. These contiguous three systems are very likely to merge together in the near future and may grow to a single more massive cluster at later times. Whilst most H_alpha emitters reside in the "blue cloud" on the color--magnitude diagram, some emitters have very red colors with J-Ks>1.38(AB). Interestingly, such red H_alpha emitters are located towards the faint end of the red sequence, and they tend to be located in the high density clumps. We do not see any statistically significant difference in the distributions of individual star formation rates or stellar masses of the H_alpha emitters between the dense clumps and the other regions, suggesting that this is one of the notable sites where the progenitors of massive galaxies in the present-day clusters were in their vigorous formation phase. Finally, we find that H_alpha emission of the radio galaxy is fairly extended spatially over ~4.5 arcsec. However it is not as widespread as its Lya halo, meaning that the Lya emission is indeed severely extended by resonant scattering.

description: We present first results from the Herschel Gould Belt survey for the B211/L1495 region in the Taurus molecular cloud. Thanks to their high sensitivity and dynamic range, the Herschel images reveal the structure of the dense, star-forming filament B211 with unprecedented detail, along with the presence of striations perpendicular to the filament and generally oriented along the magnetic field direction as traced by optical polarization vectors. Based on the column density and dust temperature maps derived from the Herschel data, we find that the radial density profile of the B211 filament approaches a power-law behavior ρ {\propto} r^(-2.0{\pm}0.4) at large radii and that the temperature profile exhibits a marked drop at small radii. The observed density and temperature profiles of the B211 filament are in good agreement with a theoretical model of a cylindrical filament undergoing gravitational contraction with a polytropic equation of state: P {\propto} ρ^γ and T {\propto} ρ^(γ-1), with γ=0.97{\pm}0.01<1 (i.e. not strictly isothermal). The morphology of the column density map, where some of the perpendicular striations are apparently connected to the B211 filament, further suggests that the material may be accreting along the striations onto the main filament. The typical velocities expected for the infalling material in this picture are ~0.5-1 km/s, which are consistent with the existing kinematical constraints from previous CO observations.

This tutorial review provides an overview of recent research efforts in non-conventional reactions and syntheses of oxides induced by mechanical action. It starts with a brief account of the history of mechanochemistry. Ensuing discussions will review the progress in homogeneous and heterogeneous mechanochemical reactions in oxides of various structures. The review demonstrates that the event of mechanically induced reactions provides novel opportunities for the non-thermal manipulation of materials and for the tailoring of their properties. © 2013 The Royal Society of Chemistry.

description: Generating non-classical states of light by opto-mechanical coupling depends critically on the mechanical and optical properties of micro-oscillators and on the minimization of thermal noise. We present an oscillating micro-mirror with a mechanical quality factor Q = 2.6x10^6 at cryogenic temperature and a Finesse of 65000, obtained thanks to an innovative approach to the design and the control of mechanical dissipation. Already at 4 K with an input laser power of 2 mW, the radiation-pressure quantum fluctuations become the main noise source, overcoming thermal noise. This feature makes our devices particularly suitable for the production of pondero-motive squeezing.

description: The assessment of health-related quality of life (QoL) in chronic conditions is considered as relevant, especially in patients with hypothyroidism where a high comorbidity with depressive and anxiety issues is reported. The present cross-sectional pilot study aims at: i) examining the correlation of thyroid-specific and generic measures of QoL in patients with Hashimoto’s Thyroiditis (HT); ii) investigating the associations of generic and thyroid-specific measures of QoL with depression and anxiety in patients with HT; iii) comparing generic and thyroid-specific measures of QoL in patients with HT versus controls. Twenty-one patients with serologically and/or ultrasonographically verified HT and sixteen controls with non-toxic goiter or post-surgical hypothyroidism were recruited for this study. Generic and disease-specific QoL were assessed by Health Survey Short Form-36 (SF-36) and Thyroid Patient Reported Outcome (ThyPRO) questionnaires, respectively, whereas depression and anxiety were measured through Beck Depression Inventory-second edition (BDI-II) and Hamilton Anxiety Rating Scale (HAM-A) questionnaires, respectively. Findings showed that ThyPRO and SF-36 scores were associated with each other only regarding the mental health domain, and that such QoL measures were consistently associated with depression levels but not with anxiety. Besides, no statistically significant difference was found between patients with HT and controls with regard to generic and thyroid-specific QoL. The present study suggests that generic and disease-specific measures of QoL can sufficiently assess the mental functioning domain and capture depressive symptoms, but only thyroid-specific measures (such as ThyPRO) can provide an accurate examination of physical aspects of QoL and the overall disease impact in patients’ lives. Besides, some methodological limitations should be taken into account in both using generic and disease-specific instruments with regard to their tendency to underestimate possible anxiety problems.

description: [Abridged] Context. The CoRoT space mission has been searching for transiting planets since the end of December 2006. Aims. We aim to investigate the capability of CoRoT to detect small-size transiting planets in short-period orbits, and to compare the number of CoRoT planets with 2 \leq R_p \leq 4 Rearth with the occurrence rate of small-size planets provided by the distribution of Kepler planetary candidates (Howard et al. 2012). Methods. We performed a test that simulates transits of super-Earths and Neptunes in real CoRoT light curves and searches for them blindly by using the LAM transit detection pipeline. Results. The CoRoT detection rate of planets with radius between 2 and 4 Rearth and orbital period P \leq 20 days is 59% (31%) around stars brighter than r'=14.0 (15.5). By properly taking the CoRoT detection rate for Neptune-size planets and the transit probability into account, we found that according to the Kepler planet occurrence rate, CoRoT should have discovered 12 \pm 2 Neptunes orbiting G and K dwarfs with P \leq 17 days in six observational runs. This estimate must be compared with the validated Neptune CoRoT-24b and five CoRoT planetary candidates in the considered range of planetary radii. We thus found a disagreement with expectations from Kepler at 3 σor 5 σ, assuming a blend fraction of 0% (six Neptunes) and 100% (one Neptune) for these candidates. Conclusions. This underabundance of CoRoT Neptunes with respect to Kepler may be due to several reasons. Regardless of the origin of the disagreement, which needs to be investigated in more detail, the noticeable deficiency of CoRoT Neptunes at short orbital periods seems to indirectly support the general trend found in Kepler data, i.e. that the frequency of small-size planets increases with increasing orbital periods and decreasing planet radii.

description: Starting from its definition, the topic of addiction has revealed its epistemological framework. Addiction derives from the Latin addictus, a term used in ancient Rome to indicate a state of slavery (Oxford English Dictionary, 2008). This study aims to understand if those who use drugs or have a behavioral disorder such as gambling disorder (Clark et al., 2013; Frisone et al., 2020a, 2020b; Frisone, 2021) should be considered mainly as slaves.

description: We show that hard spheres confined between two parallel hard plates pack denser with periodic adaptive prismatic structures which are composed of alternating prisms of spheres. The internal structure of the prisms adapts to the slit height which results in close packings for a range of plate separations, just above the distance where three intersecting square layers fit exactly between the plates. The adaptive prism phases are also observed in real-space experiments on confined sterically stabilized colloids and in Monte Carlo simulations at finite pressure.

description: The implantation of a total hip prosthesis is an operation which is performed frequently due to advanced hip jointdamage both in humans and in veterinary medicine in dogs. The long-term result of a hip prosthesis is mainly determined by aseptic loosening of the prosthesis; among other causes, abrasion particles of the tribological pairing are responsible for the loosening. For the analysis of the surface stresses with different tribological pairings, a finite element model was generated which was based on the CAD data of a commercial total hip prosthesis. After transmission of a physiological force in the components of the three tribological pairings ceramic/polyethylene, ceramic/ceramic and metal/polyethylene, stresses were calculated. Stresses in the ceramic/ceramic tribological pairings were conspicuously higher than in the other material pairings. In the future adapted prostheses have to be developed that ensure optimal friction and absorption characteristics of the components.
description: Die Implantation einer Hüfttotalendoprothese ist ein operativer Eingriff, der in Deutschland häufig aufgrund eines fortgeschrittenen Hüftgelenkschadens sowohl beim Menschen als auch in der Veterinärmedizin beim Hund durchgeführt wird. Das Langzeitergebnis einer Hüfttotalendoprothese wird hauptsächlich durch die aseptische Lockerung der Prothese bestimmt; Abriebpartikel der Gleitpaarung sind für eine Lockerung mit verantwortlich. Zur Analyse der Oberflächenspannungen bei unterschiedlichen Gleitpaarungen wurde ein Finite-Element-Modell generiert, das auf den CAD-Daten einer handelsüblichen Hüfttotalendoprothese basiert. Nach Einleitung einer physiologischen Gelenkkraft wurden Spannungen in den Komponenten der drei Gleitpaarungen Keramik/Polyethylen, Keramik/Keramik und Metall/Polyethylen berechnet. Dabei zeigten sich bei der Gleitpaarung Keramik/Keramik deutlich höhere Spitzenspannungen als bei den beiden übrigen Gleitpaarungen. In weiteren Arbeiten sollen angepasste Prothesen entwickelt werden, die optimale Reib- und Dämpfungseigenschaften der Komponenten sicherstellen.

description: Objectives: Defense mechanisms underlie a range of healthy and pathological psychological phenomena and are important mechanisms of change in psychotherapy. Thus, the identification of defense mechanisms in clinical work is crucial, however, measures commonly used for their assessment have various limitations. The Defense Mechanisms Rating Scale Q-set (DMRS-Q; Di Giuseppe, 2014) was developed to address these problems, and to provide an easy-to-use, valid, and reliable tool for the assessment of defense mechanisms. The present study aimed to evaluate the reliability of the DMRS-Q when used by trained versus untrained coders, and to examine the criterion validity of the DMRS-Q in relation to its original observer-rated version, the Defense Mechanisms Rating Scale (DMRS; Perry, 1990). Methods: Collateral sessions (n = 13) with parents of children with externalizing problems were coded with the DMRS-Q by trained and untrained raters, and on the DMRS by an expert rater. Results: We found that both trained and untrained coders were able to assess most defense categories and levels with moderate to excellent reliability on the DMRS-Q, and that untrained coders’ reliability was comparable although slightly lower than untrained coders’ reliability. Moreover, our results indicate the generally good criterion validity of the DMRS-Q when compared to the original DMRS. Discussion: These findings suggest that the DMRS-Q is a promising measure that can be used by clinicians and researchers at all levels of training and with minimal knowledge of defense mechanisms as a reliable and valid method to assess defense mechanisms in clinical settings.

description: We study synthetic aperture radar (SAR) imaging and motion estimation of complex scenes consisting of stationary and moving targets. We use the classic SAR setup with a single antenna emitting signals and receiving the echoes from the scene. The known motion estimation methods for such setups work only in simple cases, with one or a few targets in the same motion. We propose to extend the applicability of these methods to complex scenes, by complementing them with a data pre-processing step intended to separate the echoes from the stationary targets and the moving ones. We present two approaches. The first is an iteration designed to subtract the echoes from the stationary targets one by one. It estimates the location of each stationary target from a preliminary image, and then uses it to define a filter that removes its echo from the data. The second approach is based on the robust principle component analysis (PCA) method. The key observation is that with appropriate pre-processing and windowing, the discrete samples of the stationary target echoes form a low rank matrix, whereas the samples of a few moving target echoes form a high rank sparse matrix. The robust PCA method is designed to separate the low rank from the sparse part, and thus can be used for the SAR data separation. We present a brief analysis of the two methods and explain how they can be combined to improve the data separation for extended and complex imaging scenes. We also assess the performance of the methods with extensive numerical simulations.

description: Depression represents one of the most common psychological difficulties across the globe, with 21.2% of people receiving a diagnosis of major depressive disorder at some point in their lives (Auerbach et al., 2018). One of the core symptoms of depression, and psychological difficulties more generally, concerns the possession of negatively valanced thoughts (Frewen et al., 2008; Hjemdal et al., 2013; Johnstone Dallos, 2013; Myles et al., 2020; Westbrook et al., 2011). In a recent paper in the Mediterranean Journal of Clinical Psychology, Myles (2021) highlighted the critical importance of explicating the cognitive mechanisms underpinning psychological difficulties. This paper will discuss how the principles of associative learning can be used to account for the pervasiveness of negative thoughts in individuals with psychological difficulties.

description: More than 18 months have passed since the editorial dedicated to fear of contamination (Settineri Merlo, 2020a) which, like all public health editorials, has reflected on current events. Reflections on the relationship with that special object that is the disease characterized by its time and its spaces (today minor due to its global characteristics). The disease object is "special" for its complexity value that we can summarize in a multifactoriality that involves both intellectual and emotional processing. This involves risks of dispersion, a concept that is well suited to the word identity both individual and social.

description: Novel surface coatings of percutaneous implants need to be tested in biocompatibility studies. The use of animal models for testing usually involves numerous lethal biopsies for the analysis of the implant-tissue interface. In this study, optical coherence tomography (OCT) was used to monitor the reaction of the skin to a percutaneous implant in an animal model of hairless but immunocompetent mice. In vivo optical biopsies with OCT were taken at days 7 and 21 after implantation and post mortem on the day of noticeable inflammation. A Fourier-domain OCT was programmed for spoke pattern scanning schemes centered at the implant midpoint to reduce motion artifacts during in vivo imaging. Image segmentation allowed the automatic detection and morphometric analysis of the skin contour and the subcutaneous implant anchor. On the basis of the segmentation, the overall refractive index of the tissue within one OCT data set was estimated as a free parameter of a fitting algorithm, which corrects for the curved distortion of the planar implant base in the OCT images. OCT in combination with the spoke scanning scheme and image processing provided time-resolved three-dimensional optical biopsies around the implants to assess tissue morphology.

description: Temperature-dependent reflectivity and photoluminescence spectra are studied for undoped ultra-wide 150 nm and 250 nm GaAs quantum wells. It is shown that spectral features previously attributed to a size quantization of exciton motion in z-direction coincide well with energies of quantized levels for light holes. Furthermore, optical spectra reveal very similar properties at temperatures above exciton dissociation point.

description: The paper focuses on positive solutions to a coupled system of parabolic equations with nonlocal initial conditions. Such equations arise as steady-state equations in an age-structured predator-prey model with diffusion. By using global bifurcation techniques, we describe the structure of the set of positive solutions with respect to two parameters measuring the intensities of the fertility of the species. In particular, we establish co-existence steady-states, i.e. solutions which are nonnegative and nontrivial in both components.

description: We experimentally investigate the phenomenon of a quantum ratchet created by exposing a Bose-Einstein Condensate to short pulses of a potential which is periodic in both space and time. Such a ratchet is manifested by a directed current of particles, even though there is an absence of a net bias force. We confirm a recent theoretical prediction [M. Sadgrove and S. Wimberger, New J. Phys. \textbf{11}, 083027 (2009)] that the current direction can be controlled by experimental parameters which leave the underlying symmetries of the system unchanged. We demonstrate that this behavior can be understood using a single variable containing many of the experimental parameters and thus the ratchet current is describable using a single universal scaling law.

description: We surveyed households within Cirebon Metropolitan Region (CMR) in Indonesia to assess ecohydrological changes and their impacts on urban and peri-urban liveability. Composite indices were developed based on the subjective assessment of selected liveability indicators representing socio-ecohydrological functions of the region. This study identified five underlying structures of satisfaction factors, viz., personal, residential, neighbourhood, regional, and watershed. The study shows that liveability satisfaction varied depending upon the level of urbanisation in the CMR. The study also indicates that the challenge to improve regional sustainability is significant in the urban–peri-urban transition zone where the poor are more likely to live and are more directly affected by urban expansion and degradation of the local ecosystem. The analytical framework developed in this study can help local and regional government agencies to examine holistic solutions that focus more on place-based needs for long-term liveability and sustainability.

description: Ion mobility spectrometry is a well-known technique used to analyze trace gases in ambient air. Typically, it works by employing a radioactive source to provide electrons with high energy to ionize the analytes in a series of chemical reactions. During the past ten years non-radioactive sources have been one of the subjects of interest in ion mobility spectrometry, initially in order to replace radioactive sources as a result of general security and regulatory concerns. Among these non-radioactive sources especially pulsed sources have recently been shown to additionally improve the analytic information provided by ion mobility spectrometers. In this review we will describe the progress regarding the application of pulsed non-radioactive electron sources in ion mobility spectrometry and show the recent analytical advances that have been achieved by using pulsed electron beams.
Spontaneous creation and persistence of ground-state coherence in a resonantly driven intra-cavity atomic ensemble

description: The spontaneous creation and persistence of ground-state coherence in an ensemble of intracavity Rb atoms has been observed as a quantum beat. Our system realizes a quantum eraser, where the detection of a first photon prepares a superposition of ground-state Zeeman sublevels, while detection of a second erases the stored information. Beats appear in the time-delayed photon-photon coincidence rate (intensity correlation function). We study the beats theoretically and experimentally as a function of system parameters, and find them remarkably robust against perturbations such as spontaneous emission. Although beats arise most simply through single-atom-mediated quantum interference, scattering pathways involving pairs of atoms interfere also in our intracavity experiment. We present a detailed model which identifies all sources of interference and accounts for experimental realities such as imperfect pre-pumping of the atomic beam, cavity birefringence, and the transit of atoms across the cavity mode.

description: Mass spectrometric studies of the vapours over solid lead oxide in a flow of gaseous arsenic and antimony trioxides were conducted. The following ions of the ternary oxides were detected: Pb3As2O6+, Pb3AsO4+, PbAs2O4+, PbAsO2+, PbSb2O4+, and PbSbO2+. The origin of these species produced by the ionisation and/or fragmentation of ternary gaseous oxides is discussed. The PbAs2O4 species was undoubtedly identified by the determination of the appearance energy. Presumably, the Pb3As2O6 and PbSb2O4 species also existed in the gas phase. Thermodynamic data for the ternary oxides were obtained experimentally by means of a mass spectrometric Knudsen-cell method and were confirmed by quantum chemical calculations.
