Scattering of Co-Current Surface Waves on an Analogue Black Hole
2018
We report on what is to our knowledge the first scattering experiment of surface waves on an accelerating transcritical flow, which in the analogue gravity context is described by an effective spacetime with a black-hole horizon. This spacetime has been probed by an incident co-current wave, which partially scatters into an outgoing countercurrent wave on each side of the horizon. The measured scattering amplitudes are compatible with the predictions of the hydrodynamical theory, where the kinematical description in terms of the effective metric is exact.
Greening a university campus: trends of energy consumption and possible sustainable paths
2014
Recent years have seen an increasing public interest in issues related to energy saving and environmental pollution reduction of public buildings, such as those in university campuses, that should set an example of sustainable development. University campuses are usually characterized by the daily presence of a high number of people working and living in a relatively limited area. They are sites of a wide spread of functions, ranging from teaching to laboratory activities, from housing and food preparation to local transportation. All these activities require remarkable amount of energy that, actually, are not always utilized with the best possible efficiency. This calls for a deep reconsid…
Circular economy and agritourism: a sustainable behavioral model for tourists and farmers in the post-COVID era.
2023
Introduction: In recent years, issues related to environmental and ecosystem protection have been given greater consideration than in the past. The goal of adopting sustainable development models is vigorously pursued in the European Union and is reflected concretely in the new Common Agricultural Policy 20232027. The circular economy can certainly be an emerging economic response that can eectively replace growth models centered on a linear view. Agriculture and tourism are two crucial sectors where the “green transition” should be encouraged to help achieve sustainability goals through economic circularity. Agritourism’s activity may be relevant in contributing to a behavioral change based…
The Graffiti Storyline and Urban Planning : Key Narratives in the Planning, Marketing, and News Texts of Santalahti and Hiedanranta
2018
This article regards urban planning as a form of storytelling and argues that there is significance in whose stories and which storylines are acknowledged to belong to the narrative fabric of a place and how the stories of future districts are communicated to the public through narratives during a planning project. My focus is on the storyline that follows the activity of graffiti culture in the two case areas of Santalahti and Hiedanranta (located in the city of Tampere in Finland) during these areas’ phases of transition created during the redevelopment of former industrial areas into residential districts. In my discursive analysis I identify key narratives that recur in planning, market…
Data from: New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data
2019
The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with a species-specific medium-density 90K SNP panel. We estimated the levels of molecular diversity and described population structure, which r…
CA3–CA1 long‐term potentiation occurs regardless of respiration and cardiac cycle phases in urethane‐anesthetized rats
2023
Breathing and heartbeat synchronize to each other and to brain function and affect cognition in humans. However, it is not clear how cardiorespiratory rhythms modulate such basic processes as synaptic plasticity thought to underlie learning. Thus, we studied if respiration and cardiac cycle phases at burst stimulation onset affect hippocampal long-term potentiation (LTP) in the CA3–CA1 synapse in urethane-anesthetized adult male Sprague–Dawley rats. In a between-subjects design, we timed burst stimulation of the ventral hippocampal commissure (vHC) to systole or diastole either during expiration or inspiration and recorded responses throughout the hippocampus with a linear probe. As classic…
Optimisation algorithms in the case of mineral detection using Raman Analysis
2013
Abstract Raman analysis can be used to analyse the existence of minerals in an ore sample. Especially the interest here is to analyse given ore sample rapidly, to find out what minerals it contains. Rapid analysis would enable more rapid exploration of minerals as analysis could be carried out on-site. For this study, ore samples were collected from two mines in Northern Finland, Kittila and Kevitsa. An optimisation algorithm was constructed to form a linear combination of reference spectra which best represent the measured spectrum from an ore sample. The reference spectra were collected from a public source. It was found that solving for an optimal summation of reference spectra can be a …
Arm Space Decomposition as a Strategy for Tackling Large Scale Multi-armed Bandit Problems
2013
Recent multi-armed bandit based optimization schemes provide near-optimal balancing of arm exploration against arm exploitation, allowing the optimal arm to be identified with probability arbitrarily close to unity. However, the convergence speed drops dramatically as the number of bandit arms grows large, simply because singling out the optimal arm requires experimentation with all of the available arms. Furthermore, effective exploration and exploitation typically demands computational resources that grow linearly with the number of arms. Although the former problem can be remedied to some degree when prior knowledge about arm correlation is available, the latter problem persists. In this…
Carleson's counterexample and a scale of Lorentz-BMO spaces on the bitorus
2005
We introduce a full scale of Lorentz-BMO spaces BMO L p,q on the bidisk, and show that these spaces do not coincide for different values ofp andq. Our main tool is a detailed analysis of Carleson's construction in [C].
