description: By employing the first-principles GW-Bethe-Salpeter Equation (BSE) simulation, we obtain, for the first time, the accurate quasiparticle (QP) band gap, optical absorption spectra and their dependence on the gate field of gated bilayer graphene (GBLG). Many-electron effects are shown to be extremely important to understand these excited-state properties; enhanced electron-electron interactions dramatically enlarge the QP band gap; infrared optical absorption spectra are dictated by bright bound excitons. Our results well explain recent experiments and satisfyingly solve the puzzle about the inconsistency between experimentally measured transport and optical band gaps. Moreover, our calculation reveals fine excitonic structures and predicts exotic excitonic effects that have not been observed yet, which can be of interest for optoelectronics applications based on GBLG.

description: In this letter we report a fast and easy method which could be used for initial screening of multispecies-biofilm development on putative new dental implant materials. Most staining methods require numerous washing steps that can result in detachment of loosely bound biofilms and therefore falsify the results. Thus, we used glutaraldehyde fixation, which induces autofluorescence through bacterial membrane protein cross-linking and concurrently stabilizes the biofilm structure. We analyzed the biofilms with nonlinear laser scanning microscopy and were able to (I) evaluate the multispecies-biofilm growth and (II) distinguish between bacterial species based on different two-photon autofluorescence intensities. © 2016 by De Gruyter.

description: Background: This study aimed to screen a wide range of emotional and behavioural variables emerging during the first COVID-19 pandemic-lockdown in a sample of parents and children, residents in the southern part of Italy, and explore which variables could predict children’s wellbeing. We hypothesised that difficulties in adapting routines to pandemic restrictions, parents’ emotional wellbeing, and attitude towards the pandemic could influence the children’s behavioural attitudes. Methods: 221 parents completed the survey and gave information about 246 children. Ad hoc questionnaires were created and then exploratory reduced in factors. Strengths and Difficulties Questionnaire (SDQ) for parents assessed positive and negative behavioural attitudes in children. Depression Anxiety Stress Scale (Italian DASS-21) scored depression, anxiety and stress in parents. Results: Children presented higher emotional distress (Mean difference (Mdiff)=0.6, 95% C.I. 0.2, 0.9, p=0.013) and better prosocial behaviour (Mdiff=0.5, 95% C.I. 0.1, 0.9, p=0.011) than the Italian normative sample. Parents were more depressed than expected in the general population (Mdiff=1.0, 95% C.I. 0.3, 1.6, p=0.005). Having developed a morbid attachment to an adult (B=0.37, 95% CI 0.05, 0.69, p=0.024), a higher parental depression (B=0.1, 95% CI 0.02, 0.18, p=0.014), and children’s suffering from nightmares (B=0.35, 95% CI 0.03, 0.67, p=0.032) explained the 31.9% of the total variance in children’s emotional distress. Children’s anxiety was related to parents’ fear of the pandemic effects (r=0.32, p=0.001) and avoiding communicative approach (r=0.24, p=0.011). Conclusion: The first lockdown determined emotional distress and regressive mechanisms in children in the contest of higher parental discomfort, fear of the infection and avoidant communication. Following parents’ indications, it could be helpful to provide families with informative and age-appropriate support.

description: Convection is the mechanism by which energy is transported through the outermost 30% of the Sun. Solar turbulent convection is notoriously difficult to model across the entire convection zone where the density spans many orders of magnitude. In this issue of PNAS, Hanasoge et al. (2012) employ recent helioseismic observations to derive stringent empirical constraints on the amplitude of large-scale convective velocities in the solar interior. They report an upper limit that is far smaller than predicted by a popular hydrodynamic numerical simulation.

description: Purpose – Approaches for a miniaturisation of electrical machines that are based on an electromagnetic principle have to overcome numerous challenges. Some of these are only a result of the rules of growth (or shrinkage), some are a result of the micro technological fabrication processes. This paper aims to give an overview of the current state of the art including various examples of linear and rotating micro actuators that have been realised. Design/methodology/approach – The paper presents details of further miniaturisation by using thin film technology for depositing and structuring soft magnetic and hard magnetic material as well as copper for conductors and insulation. Findings – There are numerous limitations for the miniaturisation with respect to material properties, friction/guidance, etc. and this paper illustrates ways to overcome these limitations. Originality/value – The paper presents a compact overview on the achievements gained in 12 years of research within a collaborative research centre of the German DFG. © 2011, Emerald Group Publishing Limited

description: The development of collective long-range order via phase transitions occurs by the spontaneous breaking of fundamental symmetries. Magnetism is a consequence of broken time-reversal symmetry while superfluidity results from broken gauge invariance. The broken symmetry that develops below 17.5K in the heavy fermion compound URu2Si2 has long eluded such identification. Here we show that the recent observation of Ising quasiparticles in URu2Si2 results from a spinor order parameter that breaks double time-reversal symmetry, mixing states of integer and half-integer spin. Such "hastatic order" hybridizes conduction electrons with Ising 5f^{2} states of the uranium atoms to produce Ising quasiparticles; it accounts for the large entropy of condensation and the magnetic anomaly observed in torque magnetometry. Hastatic order predicts a tiny transverse moment in the conduction sea, a collosal Ising anisotropy in the nonlinear susceptibility anomaly and a resonant energy-dependent nematicity in the tunneling density of states.

description: To evaluate the factor structure and measurement invariance of the Italian translation of the UPPS-P Impulsive Behavior Scale, while providing also normative data, 797 community dwelling adults were administered the UPPS-P online. Omega coefficient values suggested adequate internal consistency reliability for all the UPPS-P scales. Weighted least square mean and variance adjusted (WLSMV) confirmatory factor analysis (CFA) showed adequate fit for the a priori five-factor model of the UPPS-P items. Measurement invariance findings supported the scalar invariance of the UPPS-P items across male and female sub-group (RMSEA = .052, CFI = .921, D-CFI = .002), thus allowing gender comparisons in terms of latent factor mean scores. Based on these findings, normative data and T scores for the UPPS-P scale score distribution among Italian community-dwelling adults were provided. Hopefully, our findings may help clinicians and researchers to use the UPPS-P in their routine assessment of impulsive behaviors.

Our results show that in the hypergeometric cases the matrix representations of monodromy relative to the Frobenius bases can be expressed in terms of the geometric invariants of the underlying Calabi-Yau threefolds. This phenomenon is also verified numerically for other families of Calabi-Yau threefolds in the paper. Furthermore, we discover that under a suitable change of bases the monodromy groups are contained in certain congruence subgroups of Sp(4, ℤ) of finite index and whose levels are related to the geometric invariants of the Calabi-Yau threefolds. © Walter de Gruyter.

We show that for deep groves there is a strong plasmonic response with light absorption in the graphene sheet reaching more than 45%, due to the excitation of surface plasmon-polaritons. The case of grating with a graphene sheet presenting an induced periodic modulation of the conductivity is also discussed.

Subjects: COVID-19; Lockdown; University students; Risk perception; Clinical psychology.

description: Background: This study aimed to explore the lockdown experience on a sample of university students during the first wave of the COVID-19 pandemic in Italy, focusing on the degree of confidence in the information received about the pandemic, the perceived health risk related to COVID-19, the psychological experiences related to quarantine, and the opinions regarding distance learning and the measures to adopt after the total lockdown. More specifically, we hypothesized that living in an area with more restrictions significantly contributes to accentuating the negative psychological impact of the quarantine experience. Furthermore, we assumed that a high perception of risk and a high fear of contracting the virus are significantly associated with more negative feelings during the lockdown. Conversely, adherence to pandemic containment measures and confidence in the information received on COVID-19 are predictors of positive emotions. Methods: 655 university students completed a battery of standardized questionnaires between April 22 and May 1, 2020. The data was analyzed through univariate, bivariate, and multivariate analysis. Results: The students showed to be highly informed about the pandemic and confident regarding the information received about the virus. Furthermore, they had a good perception of their risk of contracting COVID-19. Overall, the results highlighted a significant psychological impact of the lockdown. Students reported greater feelings of sadness (51.3%), nervousness (64.6%), and irritability (57%) than usual, with increased ruminations (70.9%). Furthermore, difficulty concentrating (55.9%), sleeping (54.5%), eating disorders (73.6%), tachycardia (65%), and a tendency to cry (65%) were also reported. Multiple regression suggests that female and younger students who lived in areas with a higher rate of contagion ("red zones") experienced more negative feelings related to quarantine. Moreover, high levels of perceived susceptibility and less compliance with government measures were associated with negative psychological experiences. Conclusions: These results show that university students represent a vulnerable population, and specific interventions are needed to protect their psychological wellbeing during the pandemic. It would be interesting to evaluate the psychological impact of the subsequent waves of contagion due to the persistence of the pandemic's stressful event.

description: The objective of this study was to test whether nanoporous silica nanoparticles can be employed as fillers in dental composite materials to improve their mechanical properties. These nanoporous silica nanoparticles were synthesized using sol-gel methods, in part modified by silanization, and thoroughly characterized. The nanoporous nanoparticles were added to dental resins to form nanocomposites (resins impregnated with nanoparticles) and hybrid composites (containing in addition conventional microfillers). The incorporation of these nanoporous nanoparticles in dental resins or composites was characterized by investigation of the complex viscosity and double bond conversion as well as by determination of flexural strength and Young's modulus. The dispersion of the nanofillers was examined by SEM and EDX imaging of fracture surfaces. Incorporation of small contents (1-3 wt%) of unmodified nanoporous particles leads to improved mechanical properties. However, the incorporation of larger contents results in particle agglomeration and declining mechanical properties. This effect is less pronounced when the surface of the particles is modified with methacrylate residues, resulting in a lower agglomeration tendency and a more homogeneous filler dispersion. Surface properties and, concomitantly, dispersibility of the nanoparticles have a strong influence on mechanical properties. But the incorporation of nanoporous instead of solid nanoparticles into dental composite materials is indeed a possibility to improve the mechanical behavior. However, modification of the surface is necessary and the key to achieving uniform dispersion and, thereby, improving mechanical properties.

description: Background: The new Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents a global threat due to its increased mortality, especially among the elderly and people with severe comorbidities, such as cancer. Objectives: Through the specific measures that have been imposed to reduce the risk of infection and death, the working hypothesis is prepared: Coronavirus disease 2019 (COVID-19) pandemic has drastically decreased the hospital admissions of cancer patients, the frequency of hospitalizations and determined an increased mortality rate through the infection with SARS-CoV-2 virus in cancer patients. Methods: For a period of 16 weeks, the hospitalizations of patients to the Chronic Oncology-Palliative Care Department of “St. Luke” Hospital for Chronic Diseases, Bucharest, were analyzed, being compared to the same period of the previous year and, also, there were patients with symptoms specific to COVID-19 infection, tested for SARS-CoV-2 by means of RT-PCR. Results: The data analysis shows a 53.7% decrease among hospitalized patients – with 51.4 for day hospitalization and 50.2% for inpatient hospitalization, during the COVID-19 pandemic. 4 patients out of the 477 admitted to the Oncology Department in this period had a positive RT-PCR SARS-CoV-2 test during their hospitalization and 5 patients with symptoms common for both cancer and COVID-19 had a negative result through specific testing (Table I, Table II). Two other patients recorded on the unit were infected with SARS-CoV-2 virus and required admission and treatment in the COVID-19 Department. The willingness of the cancer patient to consult a physician for admission has greatly decreased in the first 16 weeks from the declaration of the COVID-19 pandemic. Conclusion: Cancer patients, although at an increased risk of being infected, did not exhibit severe symptoms, and the evolution of the symptoms and the performance state after the discharge from the COVID-19 department was influenced by the age and the associated comorbidities.

description: Massive stars deeply modify their surrounding ISM via their high throughput of ionizing photons and their strong stellar winds. In this way they may create large expanding structures of neutral gas. We study a new large HI shell, labelled GS305+04-26, and its relationship with the OB association CenOB1. To carry out this study we have used a multi-wavelenght approach. We analyze neutral hydrogen (HI) line data retrieved from the Leiden-Argentina-Bonn (LAB) survey, new spectroscopic optical observations obtained at CASLEO, and make use of proper motion databases available via Internet. The analysis of the HI data reveals a large expanding structure GS305+04-26 centered at (l,b)=(305$^{\degr}$, +4$^{\degr}$) in the velocity range from -33 to -17 km/s. Based on its central velocity, -26 km/s, and using standard galactic rotation models, a distance of 2.5(+-)0.9 kpc is inferred. This structure, elliptical in shape, has major and minor axis of 440 and 270 pc, respectively. Its expansion velocity, total gaseous mass, and kinetic energy are ~8 km/s, (2.4(+-)0.5)x10^5 Mo, and (1.6(+-)0.4)x10^{50} erg, respectively. Several stars of the OB-association CenOB1 are seen projected onto, and within, the boundaries of GS305+04-26. Based on an analysis of proper motions, new members of CenOB1 are identified. The mechanical energy injected by these stars could have been the origin of this HI structure.

description: Background: Beyond unambiguous advantages of mobile phones (MP), growing evidences document its problematic use and association with mental health issues. Unintentional injuries, such as road traffic or pedestrian accidents, result from dangerous use of the MP (DUMP). The aim of our study was to estimate the prevalence of DUMP and the addiction to MP in young while driving, cycling or walking (defined as DUMP) relating to some demographic and psychological factors. Methods: A cross-sectional prevalence study was carried out on a sample of 1130 Italian university students. The use and addiction to MP were studied with Italian version of the Mobile Phone Use Questionnaire (MPUQ) and Dependence test of MP (DTMP). The Cognitive Behavioral Assessment 2.0 (CBA 2.0) was used to investigate anxiety and obsessive-compulsive disorder. Results: Result statistics showed a continuous use of MP. One third of subjects showed MP addiction, associated to female and younger students. Two thirds showed risk of DUMP, associated to male and older. The obsessive-compulsive disorder was estimated only in a small fraction and significantly correlated with DTMP. Conclusions: Our study points out the importance that information and prevention campaigns targeting specific demographic subpopulations should be sought to raise young awareness for a safe use of MP.

description: We show that a chiral nonlinear sigma model coupled to degenerate neutrons exhibits a ferromagnetic phase at high density. The magnetization is due to the axial anomaly acting on the parallel layers of neutral pion domain walls spontaneously formed at high density. The emergent magnetic field would reach the QCD scale ~ 10^19 [G], which suggests that the quantum anomaly can be a microscopic origin of the magnetars (highly magnetized neutron stars).

description: The advent of few-layer graphenes has given rise to a new family of two-dimensional systems with emergent electronic properties governed by relativistic quantum mechanics. The multiple carbon sublattices endow the electronic wavefunctions with pseudospin, a lattice analog of the relativistic electron spin, while the multilayer structure leads to electric field effect tunable electronic bands. Here we use these properties to realize giant conductance oscillations in ballistic trilayer graphene Fabry-Perot interferometers, which result from phase coherent transport through resonant bound states beneath an electrostatic barrier. We cloak these states by selectively decoupling them from the leads, resulting in transport via non-resonant states and suppression of the giant oscillations. Cloaking is achieved both classically, by manipulating quasiparticle momenta with a magnetic field, and quantum mechanically, by locally varying the pseudospin character of the carrier wavefunctions. Our results illustrate the unique potential of trilayer graphene as a versatile platform for electron optics and pseudospintronics.

description: We study the Kuramoto model on complex networks, in which natural frequencies of phase oscillators and the vertex degrees are correlated. Using the annealed network approximation and numerical simulations we explore a special case in which the natural frequencies of the oscillators and the vertex degrees are linearly coupled. We find that in uncorrelated scale-free networks with the degree distribution exponent $2 < γ< 3$, the model undergoes a first-order phase transition, while the transition becomes of the second order at $γ>3$. If $γ=3$, the phase synchronization emerges as a result of a hybrid phase transition that combines an abrupt emergence of synchronization, as in first-order phase transitions, and a critical singularity, as in second-order phase transitions. The critical fluctuations manifest themselves as avalanches in synchronization process. Comparing our analytical calculations with numerical simulations for Erdős--Rényi and scale-free networks, we demonstrate that the annealed network approach is accurate if the the mean degree and size of the network are sufficiently large. We also study analytically and numerically the Kuramoto model on star graphs and find that if the natural frequency of the central oscillator is sufficiently large in comparison to the average frequency of its neighbors, then synchronization emerges as a result of a first-order phase transition. This shows that oscillators sitting at hubs in a network may generate a discontinuous synchronization transition.

Problematic Internet Use among adolescents and young adults: a systematic review of scholars’ conceptualisations after the publication of DSM5
Creators: name: Ferrante, Lucrezia

Publisher: name: Mediterranean Journal of Clinical Psychology

Subjects: Problematic Internet Use; Review; Adolescents; Young adults.

description: Scholars’ opinions vary considerably regarding many different aspects of Problematic Internet Use (PIU), including whether it should be conceptualised as an addiction, whether it has to be seen as a discrete category or as the pole of a “normal” to pathological continuum, and whether and how the relationship between a person’s characteristics and socio-cultural environment needs to be considered. The aim of the present study is to qualitatively review the evolving body of literature on PIU among adolescents in relation to the three above-mentioned issues, in order to examine how far existing research has progressed since the publication of DSM-5. Following PRISMA guidelines, studies from 2014 to 2019 identified by a search on SCOPUS and Google Scholar were collected. The PIU conceptualisations employed in studies among adolescents and young adults were analysed. Results showed that the debate on PIU as a form of addiction or a distinct clinical disorder is far from over; nonetheless, in the scientific literature about PIU among adolescents and young adults the idea of Internet use as a way to compensate for unsatisfied needs is growing, calling for a better appreciation of what happens in the life-contexts to explain how youths move to/away from PIU over time.

description: The production rates of carbon fiber reinforced plastic (CFRP) parts are rising constantly which in turn drives research to bring a higher level of automation to the manufacturing processes of CFRP. Resin transfer molding (RTM), which is seen as a production method for high volumes, has been accelerated to a high degree. However, complex net-shape preforms are necessary for this process, which are widely manually manufactured. To face these challenges a new concept for the manufacturing of carbon fiber preforms with a form-flexible gripping, draping and joining end-effector is presented and discussed. Furthermore, this paper investigates the application of this concept, describes the initial build-up of a demonstrator, focusing on material selection and heating technology, and discusses test results with the prototype. This prototype already validates the feasibility of the proposed concept on the basis of a generic preform geometry. After a summary, this paper discusses future in-depth research concerning the concept and its application in more complex geometries. © 2015 by De Gruyter 2015.

description: Although social support has been shown to have numerous positive effects on mental health, some studies found negative associations with certain internalizing symptoms. Because the origins of these associations are uncertain, the objective of the present study included the in-depth analysis of five dimensions of social support (i.e., social support seeking as a coping strategy, availability of emotional support, emotional support received, perceived comprehension, and need for support) and their associations with depressive and anxious symptoms. The sample (n = 822) was collected through Internet and a Full Latent Variables Model was developed in which the two symptoms were used as dependent variables. Subsequently, regression analyses were conducted to evaluate how the social support dimensions are influenced by depression and anxiety. The results evidenced that availability of emotional support, perceived comprehension, and need for support had direct effects on symptoms, and emotional support received and social support seeking indirect effects. Need for support was found to be the only dimension of social support that increased symptoms, and perceived comprehension was the only dimension of social support that reduced the need for support. Anxiety and depression exhibited different effects on social support: while depression reduced social support, anxiety increased it. It was concluded that anxiety can operate, under certain circumstances, as a protective mechanism against the negative effects of depression.

Subjects: Autism spectrum disorders; Parents’ Quality of Life; Well-being; optimism; Self-esteem; Hopelessness.

description: Background: The purpose of this study is to offer a scientific contribution on the possible role of some individual variables (predisposition to optimism, self-esteem, well-being, and perceived hopelessness) on the quality of life (QoL) perception of parents of children with autism spectrum disorder (ASD), given the lack of studies that investigate these variables in the Italian context. It was assumed that parents of children with ASD have lower levels of predisposition to optimism, self-esteem, perceived well-being, and QoL and higher levels of hopelessness perception compared to the parents of children with typical development. Furthermore, it was assumed that the QoL perception of parents of children with ASD is positively predicted by their predisposition to optimism, self-esteem, and perceived well-being and negatively by hopelessness. Method: The sample was composed of 172 parents: 84 parents of children with ASD and 88 parents of typically developing children. For the evaluation of the variables considered, the following instruments were used: Life Orientation Test-revised (LOT-r, Scheier e Carver, 1985; Giannini et al., 2008), PERMA-Profiler (Giangrasso, 2018), Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965; Prezza, Trombaccia e Armento, 1997), Hopelessness Depression Symptom Questionnaire (HDSQ - Metalsky e Joiner, 1991), and the Quality of Life in Autism Questionnaire (QoLA – Eapen, 2014). Results: The results confirmed the hypotheses; in particular, the regression analysis identified optimism together with the PERMA dimensions of realization and happiness as the positive predictors and hopelessness as the negative predictor of QoL. Conclusion: This study emphasizes the need to deepen the research and, consequently, to structure adequate interventions relative to the individual factors that could play a protective role on the QoL of parents of children with ASD.

description: The Mirror Paradigm (MP) is an innovative technique that explores the influences of body representation, affect regulation, and nonverbal mirror behavior in children, adolescents and adults. The critical element of the MP is the use of a full-length mirror in front of which the interviewee is asked to answer questions about how they think and feel about their body, including perception, parental and sociocultural influences and the mind-body connection. Though research on MP is limited and focused mainly on adults, its many advantages are recognized. This narrative review aims to summarize its broad applicability, strengths and weakness and potential uses in both research and clinical settings. The review of the literature was performed through a research on PsycArticles, PsycInfo, Psychology Behavioral Sciences Collection, PubMed and Web of Science Scopus databases, plus Google Scholar and ResearchGate, including pertinent and providing quantitative or qualitative data documents. Of 505 documents, 7 articles were eligible for this review (1.4% of initial records). Results revealed three main application of the MP: 1) Body image, where MP scores have been significantly correlated to body dissatisfaction assessed through questionnaires; 2) Psychopathology, where MP scores were useful in discriminating individuals with personality disorders and internalizing, externalizing, dissociative, and disordered eating symptoms; 3) Attachment, with nonverbal expressions and narratives about relationships to important others distinguishable between secure, preoccupied, and dismissive speakers as classified in the Adult Attachment Interview. Limitations and future directions are discussed, suggesting the MP as an innovative technique and measure promising for further integration in research and clinical practice.

Future non-linear stability for solutions of the Einstein-Vlasov system of Bianchi types II and VI$_0$

description: In a recent paper arXiv:1208.4231 we have treated the future non-linear stability for reflection symmetric solutions of the Einstein-Vlasov system of Bianchi types II and VI$_0$. We have been able now to remove the reflection symmetry assumption, thus treating the non-diagonal case. Apart from the increasing complexity the methods have been essentially the same as in the diagonal case, showing that they are thus quite powerful. Here the challenge was to put the equations in a form that permits the use of the previous results. We are able to conclude that after a possible basis change the future of the non-diagonal spacetimes in consideration is asymptotically diagonal.

description: The creation of executive agencies outside core departments has been a major element of administrative reforms throughout Europe during the past two decades, driven by a managerial logic, which also has been at the core of most academic works on "agencification." In this article, the authors take a different perspective by focusing on executive agencies' influence in the policy process. The authors analyze the policy influence of a large executive agency with service delivery tasks in the context of a parliamentary system of government (Flanders, Belgium). A comparison of the agency's influence in two major policy processes shows that a complex interplay of policy content, patterns of interaction, and mutual trust with the political leadership and organizational characteristics helps in explaining the observed patterns of influence. The findings also raise normative concerns regarding potential problems of disconnecting operations from policy formulation via agencification. © 2012 SAGE Publications.
