The NEFOCAST project: Quantitative precipitation estimation based on interactive satellite terminals
No full textIn this paper we describe an algorithm to retrieve 2D rainfall fields exploiting the attenuation measurements made along satellite links. This algorithm has been developed in the framework of the project NEFOCAST, a research project funded by Tuscany region. Preliminary results show that there is a good matching between the rain rate retrieved from the satellite links’ attenuation and the rain rate measured by rain gauges and weather radar. In the future, the installation of additional devices will enable the implementation of a more sophisticated algorithm for assessing the rain rate, allowing a detailed reconstruction of the rainfall field
FPGA Accelerator for Battery Management Systems in Safety-Critical Applications
No full textLithium-Ion batteries are becoming the standard solution as power source for electrical vehicles, but the increasing request of autonomous driving capability imposes stringent safety requirements and asks to fulfil ever growing constraints to achieve the safety specifications. Several considerations must be done about the Safe Operating Area of a battery, that means maintaining the correct levels of voltage, temperature and current, as well as avoiding main power cuts due to system faults. This article proposes an FPGA implementation of a Triple Module Redundancy extension for a conventional BMS. The design of the hardware accelerator is described, the testing set-up is introduced and the results of the experimental validation process are discussed. The FPGA accelerator successfully demonstrates the full functionality and the advantages achievable by its introduction in the Battery Management System (BMS) architecture
Improving Home Oral Hygiene in Patients with Fixed Orthodontic Appliances. Evaluating Educational and Motivational Interventions
No full textFixed orthodontics presents significant challenges in maintaining proper at-home oral hygiene. The
presence of irregular surfaces, which favor bacterial accumulation, makes it difficult to control plaque
effectively, thereby increasing the risk of developing various oral diseases. In this context, education and
motivation are crucial for improving at-home oral hygiene in patients undergoing fixed orthodontic
treatments. This systematic review aimed to evaluate the effects of education and motivation on the
plaque index of patients with fixed orthodontic appliances. A search was conducted using the PubMed
and Cochrane Library databases. The systematic review followed the Preferred Reporting Items for
Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines and included randomized controlled
trials (RCTs). They had to assess treatment with fixed and home oral hygiene protocols. The p-value
was analyzed by comparing the experimental and control groups, as well as the Plaque Index (PI) of the
two groups at each follow-up. After a careful selection process, nine studies met the inclusion and
exclusion criteria and were included in the review. The results from these studies show that repeated
educational and motivational strategies, delivered through both traditional and digital methods, lead to
a reduction in the plaque index among patients who received support compared to control groups. In
fact, six out of nine studies show a statistically significant difference in terms of PI for the experimental
group. This systematic review highlights the importance of educational and motivational interventions
in helping patients maintain effective plaque control, a crucial aspect of oral health for individuals
wearing fixed orthodontic appliances. Digital tools offer a promising avenue for enhancing adherence
among orthodontic patients and reducing the risk of plaque-related conditions
The RAB5-GEF function of RIN1 regulates multiple steps during Listeria monocytogenes infection.
No full textListeria monocytogenes is a food-borne pathogenic bacterium that invades intestinal epithelial cells through a phagocytic pathway that relies on the activation of host cell RAB5 GTPases. Listeria monocytogenes must subsequently inhibit RAB5, however, in order to escape lysosome-mediated destruction. Relatively little is known about upstream RAB5 regulators during L. monocytogenes entry and phagosome escape processes in epithelial cells. Here we identify RIN1, a RAS effector and RAB5-directed guanine nucleotide exchange factor (GEF), as a host cell factor in L. monocytogenes infection. RIN1 is rapidly engaged following L. monocytogenes infection and is required for efficient invasion of intestinal epithelial cells. RIN1-mediated RAB5 activation later facilitates the fusion of phagosomes with lysosomes, promoting clearance of bacteria from the host cell. These results suggest that RIN1 is a host cell regulator that performs counterbalancing functions during early and late stages of L. monocytogenes infection, ultimately favoring pathogen clearance

No full text<p>(A) Cells transfected with control (solid) or RIN3 siRNA (dashed) were stimulated with 5 ng/ml SCF for indicated time points. Cells were stained for surface intensity of KIT and analyzed by flow cytometry. Gray line indicates unstained control. (B) Table shows the percent surface reduction of KIT from three independent flow cytometry experiments. Surface reduction at 20 minutes post stimulation is significantly increased in RIN3 knock down cells, p<0.05. (C) Immunoblot indicating the level of RIN3 knockdown. (D) Cells were transfected with RIN3 siRNA and then infected with GFP (siRNA/GFP) or RIN3 (siRIN3/RIN3) adenovirus. Surface intensity of KIT was determined by flow cytometry at 0 mins (solid) and 20 mins (dotted) post stimulation. Percent reduction: ctrl/GFP (not shown): 59%, siRIN3/GFP: 67%, siRIN3/RIN3∶57%. (E) Immunoblot for RIN3 and KIT levels in transfected/infected cells. (F) Graph represents percent surface reduction at 20 minutes post stimulation from two independent experiments. Percent reduction of ctrl/GFP versus siRIN3/RIN3 is not significant (p>0.34). Percent reduction siRIN3/GFP versus siRIN3/siRIN3 is significant (p<0.05).</p
