The sentiment analysis of tweets as a new tool to measure public perception of male erectile and ejaculatory dysfunctions
Twitter is a social network based on "tweets," short messages of up to 280 characters. Social media has been investigated in health care research to ascertain positive or negative feelings associated with several conditions but never in sexual medicin
Quantum Stochastic Walk models for quantum state discrimination
Quantum Stochastic Walks (QSW) allow for a generalization of both quantum and
classical random walks by describing the dynamic evolution of an open quantum
system on a network, with nodes corresponding to quantum states of a fixed
basis. We consider the problem of quantum state discrimination on such a
system, and we solve it by optimizing the network topology weights. Finally, we
test it on different quantum network topologies and compare it with optimal
theoretical bounds
Compulsive Hoarding Symptoms and the Role of Mindfulness Skills During Social Distancing for the COVID-19 Pandemic: An Exploratory Survey
People reporting compulsive hoarding symptoms (CHS) have lower mindfulness skills than those without such symptoms. Mindfulness skills can have the role of a protective buffer against stressful periods. The quarantine imposed to contain the COVID-19 spread had a negative impact on daily habits and healthy behaviors (including social interactions). An increased attachment to objects might be one of the under-recognized psychological consequences of these difficult times, yet no study focused on CHS. Through an online survey in men who were on quarantine during the pandemic, this exploratory survey examined the prevalence of men reporting CHS during this period and explored the role of mindfulness skills on CHS controlling for anxious-depressive/stress symptoms. Forty-three men from the general population completed the Obsessive Compulsive Inventory-Revised (OCI-R), Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) and Depression Anxiety Stress Scales-21 (DASS-21). Twenty-eight percent reported CHS. No differences on the scores of the questionnaires emerged between men with and without CHS, except on CAMS-R Attention scores. In a logistic regression analysis lower CAMS-R Attention scores predicted CHS (β = −0.34, p = 0.03). This is the first, yet preliminary investigation on CHS during quarantine. The prevalence of CHS appears higher than the rates (4%) reported in the last years before the COVID-19 outbreak. Perhaps people showed more intense hoarding tendencies during quarantine/social distancing, and this pattern should be monitored. Larger samples, longitudinal designs and clinician-rated instruments are needed to support or not our findings
FlexState: Flexible State Management of Network Functions
Network function (NF) developers have traditionally prioritized performance when creating new packet processing capabilities. This was usually driven by a market demand for highly available solutions with differentiating features running at line rate, even at the expense of flexibility and tightly-coupled monolithic designs. Today, however, the market advantage is achieved by providing more features in shorter development cycles and quickly deploying them in different operating environments. In fact, network operators are increasingly adopting continuous software delivery practices as well as new architectural styles (e.g., microservices) to decouple functionality and accelerate development. A key challenge in revisiting NF design is state management, which is usually highly optimized for a deployment by carefully selecting the underlying data store. Therefore, migrating to a data store that suits a different use case is time-consuming as it requires code refactoring and adaptation to new application programming interfaces, APIs. As a result, refactoring NF software for different environments can take up to months, reducing the pace at which new features and upgrades can be deployed in production networks. In this paper, we demonstrate experimentally that it is feasible to introduce an abstraction layer to decouple NF state management from the data store adopted while still approaching line-rate performance. We present FlexState, a state management system that exposes data store functionality as configuration options, which reduces code refactoring efforts. Experiments show that FlexState achieves significant flexibility in optimizing the state management, and accelerates deployment on new scenarios while preserving performance and scalability.Peer reviewe
Noise sensing via stochastic quantum Zeno
The dynamics of any quantum system is unavoidably influenced by the external
environment. Thus, the observation of a quantum system (probe) can allow the
measure of the environmental features. Here, to spectrally resolve a noise
field coupled to the quantum probe, we employ dissipative manipulations of the
probe, leading to so-called Stochastic Quantum Zeno (SQZ) phenomena. A quantum
system coupled to a stochastic noise field and subject to a sequence of
protective Zeno measurements slowly decays from its initial state with a
survival probability that depends both on the measurement frequency and the
noise. We present a robust sensing method to reconstruct the unkonwn noise
power spectral density by evaluating the survival probability that we obtain
when we additionally apply a set of coherent control pulses to the probe. The
joint effect of coherent control, protective measurements and noise field on
the decay provides us the desired information on the noise field
Transition, height and well-being
Using newly available data, we re-evaluate the impact of transition from plan to market on objective and subjective well-being. We find clear evidence of the high social cost of early transition reforms: cohorts born around the start of transition are shorter than their older or younger peers. The difference in height suggests that the first years of reform were accompanied by major deprivation. We provide suggestive evidence on the importance of three mechanisms which partially explain these results: the decline of GDP per capita, the deterioration of healthcare systems, and food scarcity. On the bright side, we find that cohorts that experienced transition in their infancy are now better educated and more satisfied with their lives than their counterparts. Taken together, our results imply that the transition process has been a traumatic experience, but that its negative impact has largely been overcome
Experience of vaccination against invasive bacterial diseases in Veneto Region (North east Italy)
The goal of this study was to describe and comment the experience of the Veneto Region in the bacterial invasive disease. Vaccina- tion coverage was 93% against pneumococcus and 95% against haemophilus influenzae type B. Regard to meningococcus C the coverage rate was 90.1% In children, 81% at
6 years of age and 78.2% at 15 years . The preliminary data of an active surveillance of invasive bacterial diseases show that the Streptoccoccus pneumoniae was the main agent involved and that its consequences were particularly serious in elderly subjects. With regard to Neisseria meningitidis, we observed a substantial reduction in the number of cases due to serogroup C and a concomitant rise in the percentage of cases due to serogroup B. The suspension of mandatory vaccination should be maintained , the monitoring of vaccination coverage and the active surveillance proved to be a very good assessment tools.

A Pilot Study of Gender Differences in Sexual Arousal of Patients With OCD: The Moderator Roles of Attachment and Contamination Symptoms
Sexual arousal is often impaired in patients with obsessive–compulsive disorder (OCD).
However, little is known about the factors related to this impairment: no study focused on
the role of gender-based effects of attachment styles and contamination symptoms. The
Dual Control Model assumes three processes driving sexual arousal: sexual excitation
(SE), sexual inhibition (SI) due to threat of performance failure, and SI due to threat
of performance consequences (e.g., getting contaminated with sexually transmitted
diseases). In a group of OCD patients, we hypothesized that (a) women report lower SE
and higher SI thanmen; (b) patients with insecure (both anxious and avoidant) attachment
styles show lower SE and higher SI; (c) attachment styles moderate the relation between
gender and sexual arousal (respectively, for women, higher attachment anxiety, and for
men higher attachment avoidance were related to impaired sexual arousal (higher SE and
SI) controlling for OCD severity); and (d) contamination symptoms moderate the relation
between gender and sexual impairment (women with contamination symptoms show
impaired sexual arousal). Seventy-two OCD patients (37.50% women) completed the
Obsessive–Compulsive Inventory-Revised, Attachment Styles Questionnaire and Sexual
Inhibition/Sexual Excitation Scales. In contrast with our hypotheses, women reported
higher SE and lower SI due to threat of performance consequences than men. Patients
with higher attachment avoidance (discomfort with intimacy) but also confidence in self
and others had higher SE. Women with attachment avoidance (i.e., discomfort with
intimacy) had lower SE, while women with attachment anxiety (i.e., preoccupations
with relationships) had higher SI due to negative performance consequences. Women
with contamination symptoms had higher SI due to performance failure but lower SI
due to performance consequences. The present preliminary findings suggest that sexual
arousal impairment should be evaluated during the assessment of OCD patients, and
gender-based effects of attachment styles and contamination symptoms should be
considered during personalized treatment planning
