A multi-phase multi-objective dynamic genome-scale model shows different redox balancing among yeast species in fermentation

2021

ABSTRACTYeasts constitute over 1500 species with great potential for biotechnology. Still, the yeastSaccharomyces cerevisiaedominates industrial applications and many alternative physiological capabilities of lesser-known yeasts are not being fully exploited. While comparative genomics receives substantial attention, little is known about yeasts’ metabolic specificity in batch cultures. Here we propose a multi-phase multi-objective dynamic genome-scale model of yeast batch cultures that describes the uptake of carbon and nitrogen sources and the production of primary and secondary metabolites. The model integrates a specific metabolic reconstruction, based on the consensus Yeast8, and a kin…

The Idiosincrancies of the European M&A Market

2020

This paper provides a comprehensive descriptive analysis of the European market of mergers and acquisitions (MA 2) method of payment; 3) geographical scope; 4) target’s attitude; 5) bidders’ competition; 6) industry relatedness; 7) public status of the firms involved; and 8) acquirers’ ownership of targets before and after the transaction. Additionally, we identify the similarities and differences of this market with those of the dominant market worldwide, namely the US. Both markets show similar trends in their activity and the occurrence of waves concentrated around economic shocks. However, the European market notably exhibits higher levels of friendly and cash deals.

Cryptanalysis of Knapsack Cipher Using Ant Colony Optimization

2018

Ant Colony Optimization is a search metaheuristic inspired by the behavior of real ant colonies and shown their effectiveness, robustness to solve a wide variety of complex problems. In this paper, we present a novel Ant Colony Optimization (ACO) based attack for cryptanalysis of knapsack cipher algorithm. A Cipher-text only attack is used to discover the plaintext from the cipher-text. Moreover, our approach allows us to break knapsack cryptosystem in a minimum search space when compared with other techniques. Experimental results prove that ACO can be used as an effective tool to attack knapsack cipher.

Dynamic 3D Scene Reconstruction and Enhancement

2017

International audience; In this paper, we present a 3D reconstruction and enhancement approach for high quality dynamic city scene reconstructions. We first detect and segment the moving objects using 3D Motion Segmenta-tion approach by exploiting the feature trajectories' behaviours. Getting the segmentations of both the dynamic scene parts and the static scene parts, we propose an efficient point cloud registration approach which takes the advantages of 3-point RANSAC and Iterative Closest Points algorithms to produce precise point cloud alignment. Furthermore, we proposed a point cloud smoothing and texture mapping framework to enhance the results of reconstructions for both the static a…

Persistent software transactional memory in Haskell

2021

Emerging persistent memory in commodity hardware allows byte-granular accesses to persistent state at memory speeds. However, to prevent inconsistent state in persistent memory due to unexpected system failures, different write-semantics are required compared to volatile memory. Transaction-based library solutions for persistent memory facilitate the atomic modification of persistent data in languages where memory is explicitly managed by the programmer, such as C/C++. For languages that provide extended capabilities like automatic memory management, a more native integration into the language is needed to maintain the high level of memory abstraction. It is shown in this paper how persiste…

El humor verbal en situaciones comunicativas de mediación informal

2022

El presente trabajo tiene por objeto analizar, desde una perspectiva sociopragmática (Norrick y Spitz 2008, Schnurr y Plester 2017), los usos y funciones del humor verbal en situaciones comunicativas informales de mediación. Partimos de la hipótesis de que el hablante que actúa como mediador emplea marcas e indicadores humorísticos durante su interacción con las partes en conflicto para relativizar la disputa, proteger su imagen y reconstruir las relaciones interpersonales (Jacobs 2002, Fraser 2007). En aras de verificar dicha conjetura, esta investigación utiliza el corpus Val.Es.Co. (Briz et al. 2002, Pons 2022) y analiza las secuencias conversacionales en las que se producen situaciones …

Human Inducible Hsp70: Structures, Dynamics, and Interdomain Communication from All-Atom Molecular Dynamics Simulations

2015

The 70 kDa human heat shock protein is a major molecular chaperone involved in de novo folding of proteins in vivo and refolding of proteins under stress conditions. Hsp70 is related to several "misfolding diseases" and other major pathologies, such as cancer, and is a target for new therapies. Hsp70 is comprised of two main domains: an N-terminal nucleotide binding domain (NBD) and a C-terminal substrate protein binding domain (SBD). The chaperone function of Hsp70 is based on an allosteric mechanism. Binding of ATP in NBD decreases the affinity of the substrate for SBD, and hydrolysis of ATP is promoted by binding of polypeptide segments in the SBD. No complete structure of human Hsp70 is…

Gli argenti delle confraternite di Bisacquino

2011

Le confraternite di Bisacquino nel XVIII secolo dotarono le chiese o cappelle in cui aveva sede il loro sodalizio di pregevoli suppellettili ed arredi sacri in argento, eseguiti da abili artisti palermitani, di cui si propongono i più significativi esempi The confraternities of Bisacquino in the eighteenth century equipped the churches or chapels where their association was based with valuable silver furnishings and sacred ornaments, made by skilled artists from Palermo, of which the most significant examples are proposed here.
