Abstract Background The first COVID-19 case in Kenya was confirmed on March 13 th , 2020. Here, we provide forecasts for the potential incidence rate, and magnitude, of a epidemic based observed growth rate age distribution cases China, whilst accounting demographic geographic dissimilarities between China Kenya. Methods We developed modelling framework to simulate SARS-CoV-2 transmission Kenya, KenyaCoV. KenyaCoV used both within, between, different Kenyan regions groups. parameterized...
It is crucial to monitor soil loss at the plot scale evaluate effectiveness of different management practices in mitigating erosion. The present study presents first-year results from a monitoring experiment conducted Umbria, Central Italy, on six plots (22-metre-long with 16% slope) under three systems, replicated twice: i) control (CTR), i.e., traditional bare during autumn-winter period and preparation spring for sowing cash crop (sunflower); ii) cover (CC) (CCT) where CC mixture hairy...
We investigate a stochastic model of infection dynamics based on the Susceptible-Infective-Recovered (SIR) model, where distribution recovery times can be tuned, interpolating between exponentially distributed times, as in standard SIR and after fixed infectious period. This is achieved by introducing L infective classes, compared to 1 model. For large populations, spectrum fluctuations around deterministic limit computed analytically. The demographic stochasticity has effect transforming...
We use three-dimensional phase-field simulations to investigate the dynamics of two-phase composite patterns formed upon during solidification eutectic alloys. Besides spatially periodic lamellar and rod that have been widely studied, we find there is a large number additional steady-state which exhibit stable defects. The defect density can be so high pattern completely disordered, distinction between blurred. As consequence, transition from lamellae rods not sharp, but extends over finite...
Three main mechanisms determining the dynamics of measles have been described in literature: invasion disease-free lands leading to import-dependent outbreaks, switching between annual and biennial attractors driven by seasonality, amplification stochastic fluctuations close endemic equilibrium. Here, we study importance three using a detailed geographical description human mobility. We perform individual-based simulations an SIR model gridded settlements on top which implement mobility...
For almost 15 years, the experimental correlation between protein folding rates and contact order parameter has been under scrutiny. Here, we use a simple simulation model combined with native-centric interaction potential to investigate physical roots of this empirical observation. We simulate large set circular permutants, thus eliminating dependencies rate on other properties (e.g. stability). show that rate-contact is consequence fact that, in high structures, transition state ensemble...
The widespread, and in many countries unprecedented, use of non-pharmaceutical interventions (NPIs) during the COVID-19 pandemic has highlighted need for mathematical models which can estimate impact these measures while accounting highly heterogeneous risk profile COVID-19. Models either age structure or household necessary to explicitly model NPIs are commonly used infectious disease modelling, but incorporating both levels present substantial computational challenges due their high...
Abstract Background Capture of cancer stage at diagnosis is important yet poorly reported by health services to population-based registries. In this paper we describe current completeness information for endometrial available in Australian registries; and develop validate a set rules enable registry medical coders calculate using data them (registry-derived or ‘RD-Stage’). Methodology Rules deriving RD-stage (Endometrial carcinoma) were developed the American Joint Commission on Cancer...
ABSTRACT In most bird species, males are more ornamented and compete for females, who contribute to offspring care. a minority of this pattern is reversed, with colorful females competing mates taking care parental duties. such sex-role reversed the links between ornamentation, individual quality mating success not well established. Phalaropus fulicarius (Red Phalarope) migratory shorebird regular social polyandry, in which both sexes show considerable color variation. Here, we describe sex...
We study the roughness of fracture surfaces three-dimensional samples through numerical simulations a model for quasi-static cracks known as Born Model. find exponent value ζ ≃ 0.5 measured "small length scales" in microfracturing experiments. Our confirm that at small scales can be considered quasi-static. The isotropy on crack surface is also showed. Finally, considering front, we compute exponents longitudinal and transverse fluctuations line (ζ∥ ∼ ζ⊥ 0.5). They result agreement with...
We explore the spatial and temporal spread of novel SARS-CoV-2 virus under containment measures in three European countries based on fits to data early outbreak. Using from Spain Italy, we estimate an age dependent infection fatality ratio for SARS-CoV-2, as well risks hospitalization intensive care admission. use them a model that simulates dynamics using structured, spatially detailed agent approach, explicitly incorporates governmental interventions changes mobility contact patterns...
We investigate the relationship between periodicity, synchronization and persistence of measles through simulations geographical spread on British Isles. show that establishment areas biennial periodicity depends interplay human mobility local population size locations undergoing cycles tend to be, average, synchronized in phase. however occurrences opposition phase are actually quite common correspond stable dynamics. also is strictly related circulation disease highly populated area London...
We show that the delivery of fracture work to tip an advancing planar crack is strongly reduced by surface phonon emission, leading forbidden ranges speed. The emission can be interpreted through dispersion group velocity, and Rayleigh Love branches contribute as well other high frequency wave relations. also energy release rate which enters Griffith criterion for advance described product continuum solution with a function only depends on lattice geometry describes influence emission....
This work is focused on the accelerated testing of Flash memory reliability, taking our 45 nm NOR technology as a case study to highlight some major issues that may affect investigation modern nanoscale devices. In particular, results will be shown cycling-induced threshold-voltage instabilities coming from charge trapping/detrapping in cell tunnel oxide during post-cycling data retention or bake experiments, whose characterization relies possibility reduce experimental time by an increase...
We report results on the interrelation between driving force, roughness exponent, branching and crack speed in a finite element model. show that for low applied loadings reaches values measured experiments, surface is compatible with logarithmic scaling. At higher loadings, increases, exponent approaches value at short length scales experiments. In case of high anisotropy, fully experiments anisotropic materials, we are able to interpret explicitly terms efficiency function introduced by us...
Acquired scrotal giant muscular hamartoma is an uncommon benign lesion with fewer than 10 documented cases all over the world. It characterized by a proliferation of dermal smooth muscle bundles scrotum dartos fascia. The authors report rare case acquired hamartoma, which occurred in 70-year-old severely obese and diabetic man presenting progressive enlargement swelling last year, causing marked reduction quality life cosmetic problems. patient underwent wide excision hamartomatous lesion,...
