No full textDetector R&D for the HL-LHC upgrade
No full textInternational audienceThe High Luminosity LHC (HL-LHC) is identified as the highest priority program for High EnergyPhysics, by both the European Strategy and the US Particle Physics Project Prioritization Panels [1,2].The scientific goal is to measure precisely the properties of the Higgs boson, or of any newly discoveredparticles by the start of the program, and to explore the limits for new discoveries. This will require highinstantaneous luminosity operation to collect about 3000 fb-1 of data by the end of the program. Thispaper reviews the upgrades required to the ATLAS and CMS experiments to meet these challenges, alongwith the progress of major R&D program to provide the appropriate technical solutions

Diagnostic performance of combined canine and second molar maturity for identification of growth phase
No full textBACKGROUND: The objective of this research is to analyze the diagnostic performance of the circumpubertal dental maturation stages of the mandibular canine and second molar, as individual teeth and in combination, for the identification of growth phase. METHODS: A total of 300 healthy subjects, 192 females and 108 males, were enrolled in the study (mean age, 11.4 ± 2.4 years; range, 6.8 to 17.1 years). Dental maturity was assessed through the calcification stages from panoramic radiographs of the mandibular canine and second molar. Determination of growth phase (as pre-pubertal, pubertal, and post-pubertal) was carried out according to the cervical vertebral maturation method. The diagnostic performances of the dental maturation stages, as both individual teeth and in combination, for the identification of the growth phase were evaluated using positive likelihood ratios (LHRs), with a threshold of ≥10 for satisfactory performance. RESULTS: For the individual dental maturation stages, most of these positive LHRs were ≤1.6, with values ≥10 seen only for the identification of the pre-pubertal growth phase for canine stage F and second molar stages D and E, and for the post-pubertal growth phase for second molar stage H. All of the combined dental maturation stages yielded positive LHRs up to 2.6. CONCLUSIONS: Dental maturation of either individual or combined teeth has little role in the identification of the pubertal growth spurt and should not be used to assess timing for treatments that are required to be performed at this growth phas
Evaluation of mandibular growth in a prepubertal Class I and Class II population: a longitudinal analysis
No full textObjective: This study aims to identify the presence, timing, and magnitude of a prepubertal mandibular growth spurt in a Class I and Class II population. Methods: From the Burlington and Iowa Growth study of the AAOF Craniofacial Growth Legacy Collection, 83 Class I subjects (37 females and 46 males) and 32 Class II subjects (18 males and 14 females) were identified, as having at least seven consecutive annual lateral cephalograms taken from 5 to 11 years of age. Only subjects with a normodivergent facial pattern were considered. A customized cephalometric analysis was performed, and total mandibular length, defined as the distance between Condylion (Co) and Gnathion (Gn), was calculated. Results: Overall, a significant early peak of mandibular growth was present in all the subjects analysed both in Class I (4.69 mm for males and 4.18 mm for females; P < .05) and in Class II (5.85 mm for males and 4.05 mm for females; P < .05). No differences between males and females were found for the timing of this peak (7 years for Class I and Class II females and 7 years for Class I and 6.5 years for Class II males). In males, a significantly larger peak was observed in Class II than Class I subjects (P = .007). Limitations: The main limitations of this study were the impossibility of using a suitable growth indicator to identify the timing of the early mandibular growth peak and the limited Class II records retrievable. Conclusion: This investigation suggests that a prepubertal mandibular growth peak is consistently present in both Class I and Class II males and females of clinically significant magnitude. Despite that, chronological age confirms to be unsuitable to identify this peak
Customized HIRME vs Haas expander: A 3-dimensional volumetric and surface evaluation
No full textRapid Maxillary Expansion (RME) is a commonly used intervention to address posterior crossbite and alleviate functional issues associated with anterior crowding. The purpose of the study is to compare the quality and quantity of expansion of two different Haas devices with anchorage on deciduous elements, one custom-made (HIRME), through a three-dimensional analysis of the changes in the palatine vault after expansion. The study retrospectively examined a total of 30 patients, equally divided into two groups, and showed an average increase in palatal surface area of 28.81 % for the traditional Haas expander and 24.38 % for the HIRME device. The increase in surface and volume was significant for both devices (p < 0.001), while no significant differences in surface or volume increase were found between the two devices (Haas: p = 0.365; Hirme: 0.354). This study underlined the efficacy of the custom HIRME device in increasing palatal surface and volume in patients with transverse discrepancy
Bioreceptive interfaces for biophilic urban resilience
No full textThe emerging field of Biodesign sees living organisms as embedded
in the design process to create bio-generated materials
and artefacts. To support the growth and maintenance of
these organisms, designers can adopt a Bioreceptive Design
(BD) approach, recently defined as a design approach occurring
every time materials or artefacts are intentionally designed
to be colonized by life forms. Through this approach,
the inert counterpart undergoes specific studies to reach
the best bioreceptive potential for the designated life form,
also considering the environment in which the artifact will be
placed. In urban environments, BD examples tackle vegetation
to create greener spaces and provide phytoremediation
for better air quality and biodiversity in the built environment,
in the wider view of nature-based solutions and climatic transitions
of cities.
This study addresses the possibility of developing bioreceptive
interfaces for mosses and lichens to respond to biophilic
and regenerative sustainability needs in urban contexts.
These organisms have contributed as pioneers, during the
evolution of life on our Planet, in the formation and regulation
of soil and atmosphere; moreover, they are currently used in
biomonitoring actions, also contributing to the environmental
awareness of the built environment. The paper proposes BD as
a design approach of mutual interest, aiming at responding to
the host needs and preferable environmental conditions, serving
multiple species that act as co-authors of an open-ended
design, increasing urban biodiversity, and providing resilient, restorative,
and regenerative environments.
In particular, we present some of the results of an interdisciplinary
research through design, born from the collaboration
between design and biology, aiming both to bring sustainable
and innovative solutions for the Biodesign and architecture
sectors, but also to positively affect biological activities of biomonitoring
and citizen awareness. From the design perspective,
BD is applied for the selection of those material features
that match the needs of the selected organism (e.g., porosity,
color). Moreover, the use of Computational Design has played
a crucial role in designing and prototyping bioinspired, organic
shapes and textures. From a biological perspective, the research
compares different methodologies for the bio-colonization
of artefacts to obtain the best results for the timing and
survival of the organisms. The prototypes were therefore exposed
open-air with no protection or superficial treatments in
a highly colonized area (from mosses and lichens), favoring the
attachment of spores and propagules on the surfaces. On the
other hand, some prototypes were used to test the transplant
of the organisms as an alternative and faster possibility, also
suitable for interior design.
This study points out how BD can be applicable when designing
for the living, making clear the designer’s possibilities
for adopting this approach: ranging from material design to biomimicry,
designing for not-only-human users, considering the
host’s needs and preferable growth conditions, adopting a multispecies
design approach while suggesting new relationships
among biotic and abiotic agents. The paper highlights how BD
can provide sustainable, low-maintenance, and regenerative
nature-based solutions to foster resilient urban environments
Detector R&D collider experiments
