Superallowed α Decay to Doubly Magic 100Sn

2018

We report the first observation of the 108Xe→104Te→100Sn α-decay chain. The α emitters, 108Xe [Eα=4.4(2)  MeV, T1/2=58+106−23  μs] and 104Te [Eα=4.9(2)  MeV, T1/2<18  ns], decaying into doubly magic 100Sn were produced using a fusion-evaporation reaction 54Fe(58Ni,4n)108Xe, and identified with a recoil mass separator and an implantation-decay correlation technique. This is the first time α radioactivity has been observed to a heavy self-conjugate nucleus. A previous benchmark for study of this fundamental decay mode has been the decay of 212Po into doubly magic 208Pb. Enhanced proton-neutron interactions in the N=Z parent nuclei may result in superallowed α decays with reduced α-decay wi…

A novel pilot study of automatic identification of EMF radiation effect on brain using computer vision and machine learning

2020

Abstract Electromagnetic field (EMF) radiations from mobile phones and cell tower affect brain of humans and other organisms in many ways. Exposure to EMF could lead to neurological changes causing morphological or chemical changes in the brain and other internal organs. Cellular level analysis to measure and identify the effect of mobile radiations is an expensive and long process as it requires preparing the cell suspension for the analysis. This paper presents a novel pilot study to identify changes in brain morphology under EMF exposure considering drosophila melanogaster as a specimen. The brain is automatically segmented, obtaining microscopic images from which discriminatory geometri…

Managing the complexity of green innovation

2022

PurposeGreen innovation can promote both environmental sustainability and economic growth. However, its development and implementation can be complex due to the need to align innovation activities within and across companies. In this study, the authors examined how this complexity can be managed by analyzing how individual companies combine different innovation activities to develop green innovation, and how companies along the value chain align to implement these innovations.Design/methodology/approachThe dataset comprises both interviews and a survey of senior executives from the Swedish wood construction industry. These data were first analyzed by using fuzzy set qualitative comparative …

Enseigner/Faire comprendre ce que recouvre la notion de territoire en formation d’ASS

2017

International audience; Cette contribution vise à rendre compte d'une expérience de mise en œuvre d'enseignements relatifs à la complexité des territoires en filière d'Assistant(e)s de Service Social (ASS), à l'IRTS de Franche-Comté. Il a été en effet reconnu que ces enseignements alimentaient fortement les écrits en lien avec les périodes de stage et devaient s'inscrire de manière progressive au sein des trois années deformation. Testés depuis près de trois ans, le positionnement des différentes interventions et leur mis en lien sur la durée de la formation est aujourd'hui validé et entre dans une période d'application qui donne d'ores et déjà d'excellents résultats. Nous souhaitons par ce…

Connections Between Single-Level and Bilevel Multiobjective Optimization

2011

The relationship between bilevel optimization and multiobjective optimization has been studied by several authors and there have been repeated attempts to establish a link between the two. We unify the results from the literature and generalize them for bilevel multiobjective optimization. We formulate sufficient conditions for an arbitrary binary relation to guarantee equality between the efficient set produced by the relation and the set of optimal solutions to a bilevel problem. In addition, we present specially structured bilevel multiobjective optimization problems motivated by real-life applications and an accompanying binary relation permitting their reduction to single-level multiob…

ORNAMENTAL SIGN LANGUAGE IN THE FIRST ORDER TRACERY BELTS

2010

18 pages; We consider ornamental sign language of first order where principles of sieve displacement, of asymmetric building blocks as base of ornament symmetry, color exchangeability and side equivalence principles work. The generic aspects of sieve and genesis of ornamental pattern and ornament sign in it are discussed. The hemiolia principle for ornamental genesis is introduced. The discoverer of most of these principles were artist Modris Tenisons [4, 5, 6, 7 (refs. 23, 24), 8 (ref. 65)]. Here we apply systematical research using simplest mathematical arguments. We come to conclusions that mathematical argument in arising ornament is of much more significance than simply symmetries in i…

Less Data Same Information for Event-Based Sensors: A Bioinspired Filtering and Data Reduction Algorithm

2018

Sensors provide data which need to be processed after acquisition to remove noise and extract relevant information. When the sensor is a network node and acquired data are to be transmitted to other nodes (e.g., through Ethernet), the amount of generated data from multiple nodes can overload the communication channel. The reduction of generated data implies the possibility of lower hardware requirements and less power consumption for the hardware devices. This work proposes a filtering algorithm (LDSI&mdash

Fast 3D Ray Tracing for Indoor Coverage Solutions

2016

Optimal wireless indoor network planning requires huge number of iterations and evaluations of indoor coverage for each antenna location until an optimal solution is reached. Consequently, accurate and scalable calculation of power strength for indoor scenarios becomes necessary. The contribution in this paper is to reduce the complexity of 3D ray tracing for deterministic indoor power prediction. In order to achieve that while preserving the accuracy, image theory with feasible reflection volume as preprocessing approach is introduced. This proposed algorithm stores the image, its feasible reflection volume and valid area of receiving points. Significant complexity reduction is achieved by…

COMPLIANCE PROGRAM IN LATVIAS’ BANKING SECTOR: THE RESULTS OF A SURVEY

2012

Regulators more than ever believe an efficient compliance function is a prerequisite for good corporate governance that should restore trust, integrity, and responsibility in the banks, findings in academic research has confirmed mentioned above in many countries. Compliance is key facet of governance because it shows how actually bank meets corporate responsibilities. The new guidelines in September 2011 had been issued by European Banking Authority with more attention to the compliance function. Compliance is very complex function and covers different areas: Anti-money laundering, investment protection, consumer protection, data protection and etc. Compliance complexity arises from severa…
