Denoising diffusion probabilistic models (DDPMs) have demonstrated significant potential in addressing complex image processing challenges. This paper explores the application of DDPMs in three different areas: reconstruction of remote sensing imagery affected by cloud cover, reconstruction of facial images with occluded areas, and segmentation of bodies of water from remote sensing imagery. Inpainting involves filling in missing regions in images, while DDPMs act as data generators capable of synthesizing information that alings coherently with the context of the original data. Inspired by the inpainting technique, the RePaint approach was adapted and applied to reconstruction tasks. The WaterSegDiff approach, which uses a diffusion model as a backbone, was employed for the segmentation task. To illustrate the model’s behavior and provide examples of the tasks, experiments were carrie...

This is a descriptive-evolutive, dogmatic and comparative study on the collective processes of the European Union (EU). On November 25th, 2020, the Union adopted one of its most awaited legal instruments: the firstlegislation, that is supposed to create a European collective action mechanism for monetary relief. According to Directive 2020/1828 on representative actions for the protection of the collective interests of consumers, and repealing Directive 2009/22/EC, member States have to adopt the transposing measures by December 25th, 2021, and give effect to them on and apply them to representative actions that are brought on or after June 25th, 2023. The European movement for collective litigation started approximately three decades ago. It earned official European recognition in competition law in 2005, owing to the European Commission’s Green Paper on Damages Actions for Breach of ...

Purpose. The purpose of this article is to propose a detailed methodology to estimate, model and incorporate the non-constant volatility onto a numerical tree scheme, to evaluate a real option, using a quadrinomial multiplicative recombination. Design/methodology/approach. This article uses the multiplicative quadrinomial tree numerical method with non-constant volatility, based on stochastic differential equations of the GARCH-diffusion type to value real options when the volatility is stochastic. Findings. Findings showed that in the proposed method with volatility tends to zero, the multiplicative binomial traditional method is a particular case, and results are comparable between these methodologies, as well as to the exact solution offered by the Black–Scholes model. Originality/value. The originality of this paper lies in try to model the implicit (conditional) market volatility ...

The research arises from the need to demonstrate that advertising with a priming effect can improve the domain of the vision and mission of an educational institution in students ofbasic education, specifically in their conceptions of social projection, environmental care and humanistic learning. Its objective was to determine the effects of priming in advertisingaimed at improving the domain of institutional purposes. The design was experimental, and the population, students of the VII cycle of EBR. The techniques used were the observationrecord and the survey, and descriptive statistics for information processing. The results show that advertising with a priming effect improves vision mastery, 25% more in the experimentalgroup than in the control group, and regarding the mission of the institution, the level of mastery is maintained.

The hyaluronidase from Bothrops atrox venom was purified and characterized. The effect of monovalent and divalent ions on their catalytic activity was studied, showing that the magnesium ion (150 mM) increases de activity in 40%, while glycine inhibits it by 44 %. The enzyme lacks toxic activity, when administered in albino mice in toxicity tests, but increases the hemorrhagic action of the total venom on the skin of these animals. The polyvalent botropic antivenom, was able to recognize components of the total venom of B. atrox, as well as the purified enzyme, in immunodiffusion assays. The cDNA coding for hyaluronidase from the venom of B. atrox was obtained from mRNA extracted of the fresh venom, and sequenced. The analysis of the cDNA, of 2020 bp, shows that it contains an ORF of 1350 bp that codes for a pre-enzyme of 449 amino acids, which probably is processing resulting in a matur...

This article delves into the processes of school autonomy that emerged at the beginning of the COVID-19 pandemic, from the lenses given by the analysis of the policy cycle of the federal government intervention to secure the continuity in distance education. Through a documentary review of academic literature and official documents, as well as interviews and focus groups with figures of basic and upper secondary education, it is concluded that, historically, school autonomy has been a diffuse political project in Mexico and that it was not a present axis in the government’s response to the emergency. However, some school communities have demanded recognition of their autonomy to decide and act collectively.

The climatologically changes that involve the global heating, have produced in the last decades a great reduction of glacial areas on earth, and this is evidenced by the glacial back stripping The area of study is situated into a seismotectonic zone where an intercordilleran segment has a Cordillera Blanca’s glaciers, that produces a lot of ice2 s falls, moraines landslides and great rocks. These materials fall in to glacial lakes and produce a violent damage. Huaraz city is in the Quilcay2 s alluvial fan, and consists of the fluvial-alluvial sediments Historically in Huaraz have been reported events like landslides that evidence the risk factor and increase the vulnerability of the zone due to deglatiation and lacustrine phenomena’s of Palcarraju mountain and Palcacocha lake. For the mitigation of the risk we are showing some instructions that must be diffused to the most of the peo...

In the present work the revision, deduction and application of mathematical models in the quantification of the reaction kinetics of leaching processes of national sulphided minerals in chemical systems is made. The interaction between the mineral particles and the leaching solution is controlled by three possible mechanisms: by chemical reaction, by diffusion through the porous bed and by mass transfer; Each mechanism has its own mathematical modeling and parametric conditions. Experimental runs of leaching of gold and copper minerals are presented, in which their kinetic control equations of the most relevant variables are shown. Other empirical models are also shown that are used to elucidate the phenomenology of the leaching of mineral species, call chalcopyrite, sphalerite and galena.
