Scattering Uniformity Measurements and First Reflection Analysis in a Large Nonanechoic Environment

Following previous investigation, carried out at the University of Parma in 1999 and 2000, LAE (Laboratory of Acoustics and Electroacoustics) started a new measurement campaign to compare with the original results on the same type of diffusor panels, to verify AES-4id-2001 measurement standard and to investigate the nature of scattering phenomena in more detail. Measurements are conducted on the floor of a large closed space to obtain a reflection free time window, long enough to study the first reflection from the panel; the use of sine sweep excitation signals instead of the recommended MLS ones permits to ameliorate the acquisition process. The present article discusses research background studies and the results from the first round of measurements

Caries classification and management in the context of the CariesCare International (CCI™) consensus:a clinical case study

The objective of this clinical case study is to illustrate the caries management four-step structured process, leading to personalised interventions specifc for each individual patient’s risks and needs, according to CariesCare International, derived from the International Caries Classifcation and Management System (ICCMS) for clinical practice. An 18-year-old female was diagnosed with higher caries risk at the individual level, and with several caries lesions at different severity stages, some likely active and others likely inactive. A care plan was co-created with the patient and delivered to obtain optimal health outcomes. Several issues pertinent to patient-centred care are discussed, including caries management at the individual and the tooth surface level, the preservation of tooth structure, patient’s caries risk management, and prevention and control of caries lesions. The patient’s perspective is taken into account and the health outcome focus of the system is highlighted

Network information and connected correlations

Entropy and information provide natural measures of correlation among elements in a network. We construct here the information theoretic analog of connected correlation functions: irreducible $N$--point correlation is measured by a decrease in entropy for the joint distribution of $N$ variables relative to the maximum entropy allowed by all the observed $N-1$ variable distributions. We calculate the ``connected information'' terms for several examples, and show that it also enables the decomposition of the information that is carried by a population of elements about an outside source.Comment: 4 pages, 3 figure

Weak pairwise correlations imply strongly correlated network states in a neural population

Biological networks have so many possible states that exhaustive sampling is impossible. Successful analysis thus depends on simplifying hypotheses, but experiments on many systems hint that complicated, higher order interactions among large groups of elements play an important role. In the vertebrate retina, we show that weak correlations between pairs of neurons coexist with strongly collective behavior in the responses of ten or more neurons. Surprisingly, we find that this collective behavior is described quantitatively by models that capture the observed pairwise correlations but assume no higher order interactions. These maximum entropy models are equivalent to Ising models, and predict that larger networks are completely dominated by correlation effects. This suggests that the neural code has associative or error-correcting properties, and we provide preliminary evidence for such behavior. As a first test for the generality of these ideas, we show that similar results are obtained from networks of cultured cortical neurons.Comment: Full account of work presented at the conference on Computational and Systems Neuroscience (COSYNE), 17-20 March 2005, in Salt Lake City, Utah (http://cosyne.org

Update of Laparoscopic Surgery in Borderline Ovarian Tumor: Systematic Review

Background: Borderline ovarian tumor (BOT) predominantly affects young women and is often diagnosed at an early stage. BOT accounts for 15% of all epithelial tumors. In this regard, a minimally invasive surgical approach and the ability to preserve fertility, without increasing the incidence of recurrences or worsening the prognosis, are crucial. This review aims to provide an update on the role and indications of laparoscopic surgery in BOTs. Methods: The electronic research was performed on Pubmed, Medline, and Embase. Articles published in the last 20 years (2004–2023) were included, and the following keywords were used: ‘borderline ovarian tumor’ and ‘laparoscopic surgery’, ‘borderline ovarian tumor’ and ‘minimally invasive surgery’, ‘borderline ovarian tumor’ and ‘fertility sparing’, ‘borderline ovarian tumor’ and ‘recurrence’ and ‘Borderline ovarian tumor’ and ‘relapse’. The agreement about potential relevance was reached by consensus of the researchers and according to PRISMA statement guidelines. We thoroughly reviewed all bibliographies to assess the inclusion of any further eligible studies. We excluded studies that did not align with the study’s objectives. Results: The electronic database search yielded 767 total studies. Of whom, 188 were published before 2004, 84 were case reports, and 45 were not in the English language. Of the remaining 450 studies, 148 were considered eligible for the study. We included 20 studies in this review. Conclusions: Despite the latest guidelines recommending an open approach for the treatment of BOT, the laparoscopic approach has gained popularity as a feasible and safe alternative. The use of an endo-bag, along with advanced laparoscopic skills, has made the minimally invasive approach increasingly safe, with oncological outcomes almost comparable to those of reference. Moreover, in the context of fertility-sparing surgery (FSS), laparoscopy seems to be associated with improved obstetrical outcomes, without detrimental effects on overall survival and disease-free survival. Therefore, the laparoscopic approach in the treatment of BOT appears to be a safe and effective option, especially in the case of FSS

The core curriculum in cariology: fiction or reality? Challenges about implementation

Introduction: The Core Curriculum in Cariology (CCC) was developed by ORCA and ADEE in 2010. This article summarizes challenges for the implementation of the CCC at university/country level identified at the "Education Platform" of the ORCA 2022 conference in Cagliari, Sardinia. Methods: Participants from Universities from 3 European (Italy, Poland, and UK), 2 Asian (India and Russia), and 3 American countries (Brazil, Colombia and USA) led the presentations, discussion, and generation of statements. Presentations were transcribed and summarized through qualitative content analysis. Key themes were identified, transformed into key topics, and sent to the panel for agreement. Results: Regardless of the wide variety of dental schools per country, from few (Poland n=10) to many (India n=318, Brazil n=563), or from country/continent itself, frequent challenges to CCC implementation were highlighted. These included: lack of agreement on a basic CCC as standard (96%), insufficient support or reimbursement for caries prevention and management (90%), separation between cariology and restorative dentistry (68%), focus on restorative/surgical management with prevention and non-operative management being disconnected (73%). The group agreed that the integration of cariology and restorative dentistry remains essential to enhancing evidence-based decision-making, resulting in a shift of emphasis from cure to care. Conclusion: There is variation in the level of implementation of the CCC. A frequent challenge is the disconnect between cariology and restorative dentistry. The CCC should be disseminated and promoted as a uniform blueprint/framework to facilitate the implementation of a common cariology curriculum among universities within each country, as well as internationally
