Lightfield microscopy, an emerging tool for real-time 3D imaging
2020
Integral, or lightfield, microscopy offers the possibility of capturing and processing in real time multiple views of 3D fluorescent samples captured with a single shot. In this contribution we review the recent advances in lightfield microscopy and enunciate the forthcoming challenges.

P–294 Mapping COVID–19 affected genes from blood in a Window of implantation co-expression network reveals a potentially compromised landscape
2021
Abstract Study question Could the transcriptomic and functional landscape of the window of implantation be compromised by SARS-COV–2 infection? Summary answer Some of the main genes and pathways involved in the window of implantation are affected in blood of COVID–19 patients and receptivity could be affected. What is known already There is a concern whether SARS-COV–2 can disrupt assisted reproduction treatments (ARTs) and fertility in short and long terms. In the endometrium, it was found that genes related to the viral infection (ACE2, TMPRSS2/4, CTSL/B) are involved in menstrual cycle progression, especially in the Window of Implantation (WOI). However, there are no studies describing t…
Might exogenous circular RNAs act as protein-coding transcripts in plants?
2021
Circular RNAs (circRNAs) are regulatory molecules involved in the modulation of gene expression. Although originally assumed as non-coding RNAs, recent studies have evidenced that animal circRNAs can act as translatable transcripts. The study of plant-circRNAs is incipient, and no autonomous coding plant-circRNA has been described yet. Viroids are the smallest plant-pathogenic circRNAs known to date. Since their discovery 50 years ago, viroids have been considered valuable systems for the study of the structure-function relationships in RNA, essentially because they have not been shown to have coding capacity. We used two pathogenic circRNAs (Hop stunt viroid and Eggplant latent viroid) as …
A Dynamic Viewpoint to Design Performance Management Systems in Academic Institutions: Theory and Practice
2014
This article illustrates how to design and apply Performance Management systems in academic institutions by identifying and modeling those factors affecting academic performance through a dynamic performance management view. Particularly, combining performance management with System Dynamics modeling may allow academic decision-makers to better identify key performance drivers for pursuing a sustainable performance improvement in universities. In the second section of the article, a number of examples based on empirical findings from a field project aimed at designing a dynamic performance management model for the University of Palermo (Italy) are discussed.
Innovation´s Processes and Strategy in the Service Sector
2018
STRUCTURED ABSTRACT1) Objective: The present research aims to identify how the innovative strategy affects the organizational performance and quality in processes of service sector organizations in Colombia, taking into account their production process improvements, and organizational methods. 2) Method: It was used the Survey of Development and Technological Innovation (EDIT) created by the Administrative National Department of Statistics DANE, collecting 19 subsectors and a total of 5.848 companies. 3) Theoretical Framework: This research is settled in the competitive strategy, resource based view of the firm, and innovation theory. 4) Results: Finding that the innova…
Adequate number of consumers in a liking test. Insights from resampling in seven studies
2014
The recommended number of consumers to be enrolled in a hedonic test comparing several products usually ranges from 50 to 100, at least if no liking segmentation is sought. This paper seeks to examine whether such a panel size range is adequate, by means of 7 trials with different levels of product space complexity. Five types of products were tested: Two varied in fattiness and sweetness and were tested under the same conditions in two separate laboratories (4 trials); the remaining three, varying in taste and texture, were each tested in a different laboratory (3 trials). Each of the 7 trials was run by a different laboratory. Each of the seven laboratories enrolled in its trial 150 consu…
Comparison of stereo vision techniques for cloud-top height retrieval
2007
This paper presents an ongoing study for the estimation of the cloud-top height by using only geometrical methods. In agreement with some recent studies showing that it is possible to achieve reliable height estimations not only with the classical methods based on radiative transfer, this article includes a comparison of performances of a selected set of vision algorithms devoted to extract dense disparity maps or motion fields from Infra Red stereo image pairs. This collection includes both area-based techniques and an optical flow-based method and the comparison is accomplished by using a set of cloudy scenes selected from the Along-Track Scanning Radiometer (ATSR2) database. The first gr…
Self-calibration of a PTZ Camera Using New LMI Constraints
2013
In this paper, we propose a very reliable and flexible method for self-calibrating rotating and zooming cameras - generally referred to as PTZ (Pan-Tilt-Zoom) cameras. The proposed method employs a Linear Matrix Inequality (LMI) resolution approach and allows extra tunable constraints on the intrinsic parameters to be taken into account during the process of estimating these parameters. Furthermore, the considered constraints are simultaneously enforced in all views rather than in a single reference view. The results of our experiments show that the proposed approach allows for significant improvement in terms of accuracy and robustness when compared against state of the art methods.
Learning to synthesise contradictions: an Austrian approach to bridging time concepts in the strategic theory of the firm
2012
Moving from an inquiry on the notions of time underlying strategy studies, in this paper we lay the groundwork for the elaboration of a multitemporal view of the firm. We draw on the Austrian process view in economic studies and on Nonaka's idea of synthesising capabilities to formulate a methodological framework which consents the elaboration of a multitemporal view of the resource-based firm, in which different time concepts are bridged and main actor behaviours crucial for prolonged firm success are encompassed. We then show how the multitemporal view of the firm which emerges from the deployment of the integration of the Austrian and Nonakian approaches consents the reinterpretation and…
