Using coupled hidden markov chains to estimate colonization and seed bank survival in a metapopulation of annual plants
2022
The study of ecological systems is often impeded by components that escape perfect observation, such as the trajectories of moving animals or the status of plant seed banks. These hidden components can be efficiently handled with statistical modeling by using hidden variables, which are often called latent variables.Notably, the hidden variables framework enables us to model an underlying interaction structure between variables (including random effects in regression models) and perform data clustering, which are useful tools in the analysis of ecological data.This book provides an introduction to hidden variables in ecology, through recent works on statistical modeling as well as on estima…
Optimizing the Sampling Area across an Old-Growth Forest via UAV-Borne Laser Scanning, GNSS, and Radial Surveying
2022
Aboveground biomass, volume, and basal area are among the most important structural attributes in forestry. Direct measurements are cost-intensive and time-consuming, especially for old-growth forests exhibiting a complex structure over a rugged topography. We defined a methodology to optimize the plot size and the (total) sampling area, allowing for structural attributes with a tolerable error to be estimated. The plot size was assessed by analyzing the semivariogram of a CHM model derived via UAV laser scanning, while the sampling area was based on the calculation of the absolute relative error as a function of allometric relationships. The allometric relationships allowed the structural …

Retrospective Analysis of Functional Pain among Professional Climbers
2022
Climbing became one of the official Olympic sports in 2020. The nociplastic pain mechanism is indicated as important in professional sports. Functional pain, which has not been examined in climbers until now, can be an example of nociplastic pain. This study aimed to determine functional pain locations in climbers according to gender and dominant climbing style. Climbers (n = 183) and healthy subjects (n = 160) completed an online survey focused on functional pain occurrence in the head, spine, and upper limbs. The logistic regression showed that climbing predisposes one to functional pain at: Gleno-humeral joint (odds ratio (OR): 3.06; area under the curve (AUC): 0.635), elbow (OR: 2.86; A…

2022
Background: Oily skin can be extremely problematic for sufferersand presents a great challenge for cosmetologists. This condition is characterized by an excessive amount of sebum on epidermal surface and enlarged skin pores.Modern cosmetology is able to offer a wide range of treatments that are able to reduce excess sebum secretion, and an appropriate diagnosis and cosmetic interview will allow for the selection of a suitable cosmetic treatment. If there are no contraindications for device treatments and the client is not allergic to cosmetic products, an ultrasound treatment called sonophoresis may be used. Green tea is obtained from both the leaves and buds of the Camellia sinensis plant.…
Insight on pyrimido[5,4-g]indolizine and pyrimido[4,5-c]pyrrolo[1,2-a]azepine systems as promising photosensitizers on malignant cells
2022
Searching for new small molecules as photosensitizing agents, we have developed a class of twenty-five pyrimido[5,4-g]indolizine and pyrimido[4,5-c]pyrrolo[1,2-a]azepines with a good substitution pattern defining a versatile synthetic pathway to approach the title ring system. All compounds were evaluated for their photocytotoxicity on a triple negative human breast cancer cell line (MDA-MB-231) in the dark and under UVA light (2.0 J/cm2). The most effective compounds exhibited a photoantiproliferative activity with IC50 values up to nanomolar ranges. Interestingly, these new developed compounds showed high selectivity towards cancerous cells with respect to non-cancerous ones. Moreover, fo…

Interstitial deletions of chromosome 1p: novel 1p31.3p22.2 microdeletion in a newborn with craniosynostosis, coloboma and cleft palate, and review of…
2022
Abstract Background Rearrangements of unstable DNA sequences may alter the structural integrity or the copy number of dose-sensitive genes, resulting in copy number variations. They may lead more frequently to deletions, in addition to duplications and/or inversions, which are the underlying pathogenic mechanism of a group of conditions known as genomic disorders (or also contiguous gene syndromes). Interstitial deletions of the short arm of chromosome 1 are rare, and only about 30 patients have been reported. Their clinical features are variable, in respect of the extent of the deleted region. They include global developmental delay, central nervous system (CNS) malformations, craniosynost…
Adiós justicia arbitral, adiós? El fomento de la figura de la desestimación temprana de la demanda (“early dismissal”) como síntoma
2022
La desestimación temprana de la demanda es una figura consolidada en el arbitraje de inversiones que, en los últimos tiempos, está en fase de extrapolación al arbitraje comercial internacional. No se trata de un proceso ni neutro ni intrascendente, generando todo tipo de dudas y críticas, como lo demuestran los amplios debates mantenidos en el seno del Grupo de Trabajo II de la CNUDMI en relación con ella. En la discusión subyace la tensión entre la búsqueda de la máxima eficiencia en el proceso arbitral, y la salvaguarda del derecho de las partes a hacer valer plenamente sus derechos, y al debido proceso. Así como el interrogante de importar en el arbitraje instituciones procesales anglosa…
Accuracy of the clinical diagnosis of dementia with Lewy bodies (DLB) among the Italian Dementia Centers: a study by the Italian DLB study group (DLB…
2022
Introduction: Dementia with Lewy bodies (DLB) may represent a diagnostic challenge, since its clinical picture overlaps with other dementia. Two toolkits have been developed to aid the clinician to diagnose DLB: the Lewy Body Composite Risk Score (LBCRS) and the Assessment Toolkit for DLB (AT-DLB). We aim to evaluate the reliability of these two questionnaires, and their ability to enhance the interpretation of the international consensus diagnostic criteria. Methods: LBCRS and AT-DLB were distributed to 135 Italian Neurological Centers for Cognitive Decline and Dementia (CDCDs), with the indication to administer them to all patients with dementia referred within the subsequent 3 months. We…

Heat Shock Proteins Alterations in Rheumatoid Arthritis
2022
Rheumatoid arthritis (RA) is a chronic inflammatory and autoimmune disease characterized by the attack of the immune system on the body’s healthy joint lining and degeneration of articular structures. This disease involves an increased release of inflammatory mediators in the affected joint that sensitize sensory neurons and create a positive feedback loop to further enhance their release. Among these mediators, the cytokines and neuropeptides are responsible for the crippling pain and the persistent neurogenic inflammation associated with RA. More importantly, specific proteins released either centrally or peripherally have been shown to play opposing roles in the pathogenesis of this dise…
In Vitro Biocompatibility of Several Children's Toothpastes on Human Gingival Fibroblasts
2022
The European Academy of Paediatric Dentistry has recommended fluoride toothpastes from the eruption of the first teeth in children. Toothpastes stay in the mouth in contact with human gingival fibroblasts (hGFs) for a long time. Thus, the objective of this study was to compare the cytotoxicity of five different commonly used children’s toothpastes: Oral B Kids +3 (Procter & Gamble, Alicante, Spain), Fluor Kin Calcium (Kin, Madrid, Spain), PHB Junior (PHB, Barcelona, Spain), Colgate +3 (Colgate Palmolive, Madrid, Spain) and Vitis Kids (Dentaid, Valencia, Spain) on hGFs. The children’s toothpastes were exposed to hGFs at different concentrations (1:1, 1:2, 1:4). Afterwards, several tests …
Acceptance and Commitment Therapy Group Intervention for Parents of Children with Disabilities (Navigator ACT): An Open Feasibility Trial
2022
AbstractParents of children with autism spectrum disorder and other disabilities report high levels of distress, but systematically evaluated interventions are few. This study aimed to evaluate the feasibility of a novel, manualized Acceptance and Commitment Therapy group intervention (Navigator ACT) in a sample of 94 parents of children with disabilities. Feasibility was measured by treatment completion, credibility, and satisfaction, and preliminary outcomes by using self-rating scales administered at the baseline, post-intervention, and follow-up. The results imply the intervention is feasible in the context of Swedish outpatient habilitation services. A preliminary analysis of the outco…

Occurrence of Antibiotic Resistance in the Mediterranean Sea
2022
Seawater could be considered a reservoir of antibiotic-resistant bacteria and antibiotic resistance genes. In this communication, we evaluated the presence of bacterial strains in seawater collected from different coasts of Sicily by combining microbiological and molecular methods. Specifically, we isolated viable bacteria that were tested for their antibiotic resistance profile and detected both antibiotic and heavy metal resistance genes. Both antibiotic-resistant Gram-negative bacteria, Vibrio and Aeromonas, and specific antibiotic resistance genes were found in the seawater samples. Alarming levels of resistance were determined towards cefazolin, streptomycin, amoxicillin/clavulanic aci…
Size–Abundance Relationships of Freshwater Macroinvertebrates in Two Contrasting Floodplain Channels of Rhone River
2022
Body size is perhaps the most fundamental property of an organism and its relationship with abundance is one of the most studied relationships in ecology. Although numerous studies have examined these relationships in local communities, few have investigated how they vary at different temporal and spatial scales. We investigated the relationship between body size and abundance of local macroinvertebrate communities in two floodplain channels of the French upper Rhone River. The two channels differ in their vegetation coverage (high vs. low vegetation) and hydrological regimes. The shapes of the size–abundance relationship were similar between channels on a yearly basis but differed wh…
Iterative Multiple Bounding-Box Refinements for Visual Tracking.
2022
Single-object visual tracking aims at locating a target in each video frame by predicting the bounding box of the object. Recent approaches have adopted iterative procedures to gradually refine the bounding box and locate the target in the image. In such approaches, the deep model takes as input the image patch corresponding to the currently estimated target bounding box, and provides as output the probability associated with each of the possible bounding box refinements, generally defined as a discrete set of linear transformations of the bounding box center and size. At each iteration, only one transformation is applied, and supervised training of the model may introduce an inherent ambig…

Protection de la ressource en eau du bassin de l’Auxerrois et transformation des pratiques agricoles
2022
Avec des taux de nitrates dépassant les seuils définis par la Directive européenne « nitrates », puis la présence de résidus de pesticides utilisés par les activités agricoles du secteur, l’eau des bassins d’alimentation de captages de l’Auxerrois fait l’objet de préoccupations depuis une trentaine d’année. C’est ainsi qu’à la fin des années 1990, les représentants des pouvoirs publics ont choisi de mettre en place une démarche préventive passant par un travail de transformation des pratiques agricoles. Notre article analyse comment la prise en charge collective de cette situation participe à la configuration des relations entre représentants des pouvoirs publics, agriculteurs et défenseurs…

Reflections on the human role in AI policy formulations : how do national AI strategies view people?
2022
Abstract Purpose There is no artificial intelligence (AI) without people. People design and develop AI; they modify and use it and they have to reorganize the ways they have carried out tasks in their work and everyday life. National strategies are documents made to describe how different nations foster AI and as human dimensions are such an important aspect of AI, this study sought to investigate major national strategy documents to determine how they view the human role in emerging AI societies. Approach Our method for analyzing the strategies was conceptual analysis since the development of technology is embedded with conceptual ideas of humanity, explicit or implicit, and in addition to…
Samtal om Budkavlen : hågkomster från 1970–1990-talen
2022
Med anledning av Budkavlens 100-årsjubileum fick jag i uppdrag att intervjua två av tidskriftens tidigare medarbetare – professor emeritus Nils Storå och intendent John Hackman – om deras erfarenheter av utgivningen av tidskriften under 1970–1990-talen. Nils Storå (f. 1933) var professor i nordisk etnologi under åren 1972–1997 och John Hackman (f. 1942) var amanuens vid Sjöhistoriska museet 1972–1975 och därefter intendent vid Etnologiska institutionen fram till sin pensionering 2005. Texten nedan ger en bild av hur det var att driva en humanistisk vetenskaplig tidskrift under 1900-talets sista decennier.

Teacher Agency and Futures Thinking
2022
Problems encountered in top-down school reforms have repeatedly highlighted the significance of teachers’ agency in educational change. At the same time, temporality has been identified as a key element in teachers’ agency, with teachers’ beliefs about the future and experiences of the past shaping their agentic orientations. However, research on teachers’ future orientations is typically limited to short-term trajectories, as opposed to long-term visions of education. To address this, we draw on a futures studies perspective to give more explicit attention to teachers’ long-term visions of their work. We argue that the method of future narratives, already well…

Retrieval of Crop Variables from Proximal Multispectral UAV Image Data Using PROSAIL in Maize Canopy
2022
Mapping crop variables at different growth stages is crucial to inform farmers and plant breeders about the crop status. For mapping purposes, inversion of canopy radiative transfer models (RTMs) is a viable alternative to parametric and non-parametric regression models, which often lack transferability in time and space. Due to the physical nature of RTMs, inversion outputs can be delivered in sound physical units that reflect the underlying processes in the canopy. In this study, we explored the capabilities of the coupled leaf–canopy RTM PROSAIL applied to high-spatial-resolution (0.015 m) multispectral unmanned aerial vehicle (UAV) data to retrieve the leaf chlorophyll content (LC…
