Pseudorandomness Analysis of the Lai-Massey Scheme
No full textAt Asiacrypt’99, Vaudenay modified the structure in the IDEA cipher to a new scheme, which they called as the Lai-Massey scheme. It is proved that 3-round Lai-Massey scheme is sufficient for pseudorandomness and 4-round Lai-Massey scheme is sufficient for strong pseudorandomness. But the author didn’t point out whether three rounds and four rounds are necessary for the pseudorandomness and strong pseudorandomness of the Lai-Massey Scheme. In this paper we find a two round pseudorandomness distinguisher and a three-round strong pseudorandomness distinguisher, thus prove that three rounds is necessary for the pseudorandomness and four rounds is necessary for the strong pseudorandomness
The theory and practice of utopia in our troubled times : a conversation with author Larissa Lai and critic Sherryl Vint
No full textAmid current global crises, the international conference “The Knock at the Door: Utopian Dreams for Post-Covid Times,” jointly organized by the University of Huelva (Spain) and the University of Calgary (Canada) on May 21–24, 2023, at the University of Huelva, provided a forum for reflecting upon the role played by speculative fiction in (re)imagining better futures, while remaining vigilant to possible threats and dangers. The title of the conference, borrowed from philosopher John Rajchman,1 is intentionally ambiguous. Lying behind that door could be total liberation for all—or it could be secret police who lead us toward genocides, deportation, rapes, and mass graves. Taking this dichotomous trope, “the knock at the door,” as a point of departure, professors Larissa Lai (University of Toronto, Canada; recipient of a Maria Zambrano fellowship at the University of Huelva at the time of the interview) and Sherryl Vint (University of California Riverside, USA) engaged...Depto. de Estudios Ingleses: Lingüística y LiteraturaFac. de Ciencias Económicas y EmpresarialesTRUEpu
Optical instruments for measuring leaf area index in low vegetation : application in Arctic ecosystems

The definitive version was published in Ecological Applications 15 (2005): 1462–1470, doi:10.1890/03-5354.Leaf area index (LAI) is a powerful diagnostic of plant productivity. Despite the fact that many methods have been developed to quantify LAI, both directly and indirectly, leaf area index remains difficult to quantify accurately, owing to large spatial and temporal variability. The gap-fraction technique is widely used to estimate the LAI indirectly. However, for low-stature vegetation, the gap-fraction sensor either cannot get totally underneath the plant canopy, thereby missing part of the leaf area present, or is too close to the individual leaves of the canopy, which leads to a large distortion of the LAI estimate. We set out to develop a methodology for easy and accurate nondestructive assessment of the variability of LAI in low-stature vegetation. We developed and tested the methodology in an arctic landscape close to Abisko, Sweden.
The LAI of arctic vegetation could be estimated accurately and rapidly by combining field measurements of canopy reflectance (NDVI) and light penetration through the canopy (gap-fraction analysis using a LI-COR LAI-2000). By combining the two methodologies, the limitations of each could be circumvented, and a significantly increased accuracy of the LAI estimates was obtained. The combination of an NDVI sensor for sparser vegetation and a LAI-2000 for denser vegetation could explain 81% of the variance of LAI measured by destructive harvest. We used the method to quantify the spatial variability and the associated uncertainty of leaf area index in a small catchment area.This research was funded by U.S. National Science Foundation
