On the decay law for unstable open systems

We use (nonconservative) dynamical semigroups to investigate the decay law of a quantum unstable system weakly coupled with a large environment. We find that the deviations from the classical exponential law are small and can be safely ignored in any actual experiment.Comment: 12 pages, plain-TeX, to appear in Phys. Lett.

Density Estimates and Habitat Preferences of Two Sympatric Bird Species as Potential Bioindicators of Tropical Forest Alterations

Forestry management can shape the structure of habitat types and have important biological consequences on the composition of biodiversity. This study focused on Momotus lessonii and Eumomota superciliosa, two potential bioindicators of local and wide scale tropical forest alterations. The study took place in the Karen Mogensen Wildlife Refuge (Costa Rica), a protected area characterized by two main forest habitats where the two species coexist, i.e., primary moist and second-growth dry forest. A distance sampling method was used to obtain density estimates for each species. A spot mapping approach showed an apparent partitioning of the two species at the site. The Kilometric Abundance Index (KAI) and statistical analyses revealed significant differences between the two habitats, i.e., E. superciliosa tended to be more abundant and preferred the dry forest, whilst M. lessonii favored moist environments. The development of arid and semi-arid environments characterized by open areas will probably lead to a numerical increase in E. superciliosa with a consequent expansion, while the decline of moister and homogeneously forested environments will likely affect negatively M. lessonii. We argue that these birds will act as bioindicators of local and global environmental changes, and their monitoring will enable appropriate forest management decisions for conservation purposes

A hair-tube survey of small mammals from Serra di Ivrea (NW Italy)

Natura 2000 is the largest coordinated network of protected areas in the world and the main tool for biodiversity conservation within the European Union. Monitoring the protected habitats and species in all network sites by efficient survey methods is essential to plan effective conservation strategies. Small mammals, although including species of conservation interest and being major components of the food web, are often understudied. Through an intensive survey, we investigated the small mammal community of the Special Area of Conservation IT1110057 Serra di Ivrea (Piedmont, NW Italy). We overimposed a 1×1 km grid to the study area and selected a random linear transect in each cell. From mid-May to midJune 2016 we collected small mammal presence data along 55 transects, where we set 955 hair-tubes of 60 mm (n=369) and 30 mm (n=586) in diameter, in a number proportional to each transect length. The largest hair-tubes were positioned on trunks or horizontal branches of trees (ca. 160 cm above ground level) about 100 m from each other, whereas the smallest tubes were tied to shrubs (ca. 80 cm a.g.l.) with 30 m spacing. A bait (hazelnut cream) was used to attract animals and an adhesive strip was attached at each end of the tube to collect the hairs. We checked the hair-tubes twice, with an interval of 15 days. We examined the hairs using a microscope (20× and 40× magnifications) and species were identified by comparing the characteristics of the cuticle scale pattern, medulla and cross-section of the hairs. To collect information on ground-dwelling species, in September 2019 we carried out a four-nights capture session using Sherman traps (7.5×9×23 cm). We placed 10 traps at a distance of 10 m from each other along each of three selected transects. Hazelnut cream was spread at the entrance of each trap, while seeds, a slice of apple and cotton were put at the bottom. Traps were checked daily and trapped individuals were sexed and weighted before being released at the site of capture. In 28650 trap-days we found 185 positive hair-tubes. We detected a total of five to six species: Sciurus vulgaris, Eliomys quercinus, Moscardinus avellanarius, Glis glis and Apodemus sylvaticus/flavicollis, mice’s hairs being indistinguishable by hair morphology. Most occurrences were in the second check (n=156) when we found 126 Apodemus sp., 15 Sciurus vulgaris, 7 Eliomys quercinus, 6 Moscardinus avellanarius and 2 Glis glis. In the first check (n=29) only 19 Apodemus sp., 3 Sciurus vulgaris, 4 Eliomys quercinus and 3 Moscardinus avellanarius were detected. Overall, 168 presence data were collected: 132 Apodemus sp. (13.82%), 17 Sciurus vulgaris (1.78%), 10 Eliomys quercinus (1.05%), 7 Moscardinus avellanarius (0.73%) and 2 Glis glis (0.21%). Sherman trapping allowed detection of 41 small rodents belonging to two species: Apodemus sylvaticus (92.7%) and Myodes glareolus (7.3%). Hair-trapping allowed to record a species not included in the SAC Standard Data Form, namely Moscardinus avellanarius, included in Annex 4 of the Habitats Directive, and also an elusive and understudied species such as Eliomys quercinus. Hair-tubes are a non-invasive and cost-effective method to get information on small mammal distribution. Anyway, considering the number of hair-tubes deployed, capture success was low, also for a potentially common species such as Glis glis, suggesting that a large trapping effort is needed for assessing spatial niche overlap between ecologically similar species and their habitat preferences. The simultaneous use of multiple survey methods may provide a more complete assessment of the small mammal community and allow to collect more reliable data about the genus Apodemus and others ground-dwelling species such as Myodes glareolus

Outcomes of patient education in adult oncologic patients receiving oral anticancer agents: a systematic review protocol

Background: A large variety of oral anticancer agents have become available and while at first glance these therapies appear to provide only benefits, patients have expressed their need for educational interventions and raised safety issues. Although both patients and providers have recognized patient education’s importance, and an interplay with safety has been acknowledged, no systematic reviews of the literature that summarize all of the current evidence related to patient education’s outcomes for patients who receive oral anticancer agents have been performed to date. Accordingly, this systematic review will attempt to fill the gap in the literature as well as to map (1) contents, (2) methodologies, (3) settings, (4) timing/duration, and (5) healthcare professionals involved. Methods: This protocol is being reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic review will be performed. Studies that targeted eligible adult patients (≥ 18 years old) in hospital, outpatient, and home settings, and reported patient education’s outcomes for those taking oral anticancer agents will be included. Searches will be conducted in PubMed/MEDLINE, CINAHL, Embase, and Scopus, and gray literature will be also sought. Two researchers will screen the search results independently and blindly in two phases: (1) title/abstract screening and (2) full-text screening using the Rayyan AI platform. An electronic data extraction form will be implemented and piloted, and then, two trained data extractors will extract the data cooperatively. Thereafter, a quality appraisal will be conducted using the Critical Appraisal Tools from The Joanna Briggs Institute. The results will be analyzed, grouped, clustered into categories, and discussed until a consensus is reached. Emerging evidence will be synthesized narratively and reported in accordance with the synthesis without meta-analysis guidelines. Discussion: The systematic review’s results will be relevant to (1) policymakers and management at an institutional level, and (2) for clinical practice, in an evidence-based paradigm, potentially leading to a quality improvement with respect to safety and patient satisfaction.

A Lower/Upper Solutions Result for Generalised Radial p-Laplacian Boundary Value Problems

We provide existence results to some planar nonlinear boundary value problems, in the presence of lower and upper solutions. Our results apply to a class of systems generalising radial elliptic equations driven by the p-Laplace operator, and to some problems involving the Laplace–Beltrami operator on the sphere. After extending the definition of lower and upper solutions to the planar system, we prove our results by a shooting method involving a careful analysis of the solutions in the phase plane

On the Absence of the Zeno Effect in Relativistic Quantum Field Theory

We study the time evolution of decaying particles in renormalizable models of Relativistic Quantum Field Theory. Significant differences between the latter and Non Relativistic Quantum Mechanics are found -in particular, the Zeno effect seems to be absent in such RQFT models. Conventional renormalization yields finite time behavior in some cases but fails to produce finite survival probabilities in others.Comment: Revised version of the paper Time evolution and Zeno effect in relativistic quantum field theory.
