Cloaking In-Plane Elastic Waves with Swiss Rolls

2020

We propose a design of cylindrical cloak for coupled in-plane shear waves consisting of concentric layers of sub-wavelength resonant stress-free inclusions shaped as Swiss rolls. The scaling factor between inclusions&rsquo

A novel cell wall protein specific to the mycelial form of Yarrowia lipolytica.

1996

A cDNA clone specifying a cell wall protein was isolated from a Yarrowia lipolytica cDNA library. The cDNA library was constructed in the expression vector lambda gt 11, with the RNA isolated from actively growing mycelial cells. The deduced amino acid sequence shows that the encoded protein contains an N-terminal hydrophobic signal peptide. We have designated this protein YWP1 for Yarrowia lipolytica cell Wall Protein. Northern hybridization identified YWP1 transcript only when Y. lipolytica was growing in the mycelial form. The encoded protein seems to be covalently bound to the glucan cell wall since it is not released from the cell walls by sodium dodecyl sulphate extraction, but it is …

Candida albicans TDH3 gene promotes secretion of internal invertase when expressed in Saccharomyces cerevisiae as a glyceraldehyde-3-phosphate dehydr…

2003

We have checked the ability of the Candida albicans GAPDH polypeptide, which lacks a conventional N-terminal signal peptide, to reach the cell wall in Saccharomyces cerevisiae by using an intracellular form of the yeast invertase as a reporter protein. A hybrid TDH3-SUC2 gene containing the C. albicans TDH3 promoter sequences and a coding region encoding a fusion protein formed by the C. albicans GAPDH polypeptide, fused at its C-terminus with the yeast internal invertase, was constructed in a centromer derivative plasmid and transformed into a Suc(-) S. cerevisiae strain. Transformants displayed invertase activity measured in intact whole cells, and were able to grow on sucrose as the sole…

Pikosekunžu precizitātes laika intervālu mērīšanas un analīzes skaitlisko metožu izstrāde satelītu lāzerlokācijā pielietojumam

2002

Lāzerlokācijas metožu izmantošana zinātniskās programmās, kuras saistītas ar globālās ģeocentrisko koordinātu sistēmas definēšanu, Zemes rotācijas tekošo parametru noteikšanu, Zemes polu kustības mērījumiem, kontinentu dreifa noteikšanu, iespējamo zemestrīču prognozēšanu, prasa ļoti augstas precizitātes (0.5-2 cm) satelītu attālumu mērījumu rezultātus. Eksistējošie lāzeru tālmēri, daudzos gadījumos, nepilnīgi atbilst šīm prasībām, dodot precizitāti ap 4 cm. Risinot minētos lokācijas uzdevumus, liela loma ir laika intervālu analizatoru augstai izšķiršanas spējai. Satelītu lokācijā laika intervāla atsevišķa mērījuma vidējā kvadrātiskā kļūda nedrīkst pārsniegt dažus desmitus pikosekunžu, pie i…

Computing the Arrangement of Circles on a Sphere, with Applications in Structural Biology

2009

International audience; Balls and spheres are the simplest modeling primitives after affine ones, which accounts for their ubiquitousness in Computer Science and Applied Mathematics. Amongst the many applications, we may cite their prevalence when it comes to modeling our ambient 3D space, or to handle molecular shapes using Van der Waals models. If most of the applications developed so far are based upon simple geometric tests between balls, in particular the intersection test, a number of applications would obviously benefit from finer pieces of information. Consider a sphere $S_0$ and a list of circles on it, each such circle stemming from the intersection between $S_0$ and another spher…

Leaders’ Style, Self-Sacrifice, and Team Identification

2013

Leadership is a group feature that directly impacts on team identification. Effective leaders are especially capable of fostering group cohesiveness and promoting efficacy in goal attainment. We assessed the relationship between transactional and transformational leadership style, team identification, and leader self-sacrifice. Participants were 186 call center employees who were headed by a leader who operated with either a transactional or a transformational leadership style. The employees reported their level of team identification and leader self-sacrifice. Results show how, in either the transactional or transformational leadership condition, levels of leadership and self-sacrifice wer…

Fostering transformational teacher agency in Finnish teacher education

2018

In this article, we studied how well teacher education in Finland is able to answer the changing needs of the contemporary world. More precisely, we focussed on the question of how well an alternative teacher education model guides teacher students’ agency towards a transformational view of the teaching profession, making it possible for schools to enable social change. This question was studied in the framework of critical social pedagogy. The data for this article was collected ethnographically by observing meetings in the Critical Integrative Teacher Education (CITE) programme at the University of Jyväskylä in 2015–2017. The analysis is based on a theoretical background in which we outli…

‘Landscape of exception’: Power inequalities and ethical planning challenges in the landscape transformation of south-eastern Sicily

2021

In some marginal contexts of Southern Italy, in light of specific economic, political and social conditions, certain relationships between ‘strong powers’ and ‘weak powers’ produce a suspension of norms/rights that is, paradoxically, ‘normalised’. This creates a particular spatial variation of Agamben’s (2005) state of exception concept: the ‘landscape of exception’. With respect to the possible conditions of ‘exception’, this article describes the ‘landscape of exception’ of the greenhouse system in South-Eastern Sicily. This ‘landscape of exception’ is generated by the greenhouses, in particular those dedicated to vegetable production, through an effective mechanism of spatial manipulati…

Leadership in virtual teams: a comparison of transformational and transactional leaders

2009

The effects of transactional and transformational leadership on groups in which people interact in a virtual manner were analyzed and specifically the level of satisfaction and perception of the style adopted were evaluated. Results indicated that a transformational style is more satisfying than a transactional style, and that a transformational leader is judged to be better than a transactional leader.
