AN EXPERIMENTAL WORKFLOW FOR THE VIRTUAL RECONSTRUCTION OF ANCIENT STATUES

2021

The work aims to investigate the main steps of a virtual reconstruction process of ancient statues, inspecting theoretical and technical approaches. Two fragmentary Roman statues from the "Sanctuary of Isis", inside the Archaeological Park of Lilibeo-Marsala (Italy), were chosen as a case study. Trying to preserve the original artwork authenticity and the transparency of the reconstruction method, a workflow was developed following three steps: 1) 3D survey and reality based model production; 2) evaluation of reconstruction hypotheses based on a rigorous selection of reference sources; 3) 3D modelling and source-based model creation. Three models for multiple visualization purposes were car…

Preventing reverse engineering of native and managed programs

2015

One of the important aspects of protecting software from attack, theft of algorithms, or illegal software use is eliminating the possibility of performing reverse engineering. One common method used to deal with these issues is code obfuscation. However, it is proven to be ineffective. Code encryption is a much more effective means of defying reverse engineering, but it requires managing a cryptographic key available to none but the permissible users. The thesis presents a system for managing cryptographic keys in a protected environment and supporting execution of encrypted code. The system has strong security guarantees. In particular, the cryptographic keys are never stored on the target…

STAT1 and Its Crucial Role in the Control of Viral Infections

2022

The signal transducer and activator of transcription (STAT) 1 protein plays a key role in the immune response against viruses and other pathogens by transducing, in the nucleus, the signal from type I, type II and type III IFNs. STAT1 activates the transcription of hundreds of genes, some of which have been well characterized for their antiviral properties. STAT1 gene deletion in mice and complete STAT1 deficiency in humans both cause rapid death from severe infections. STAT1 plays a key role in the immunoglobulin class-switch recombination through the upregulation of T-bet; it also plays a key role in the production of T-bet+ memory B cells that contribute to tissue-resident humoral memory…

Game-Theoretic Approach to Hölder Regularity for PDEs Involving Eigenvalues of the Hessian

2021

AbstractWe prove a local Hölder estimate for any exponent $0<\delta <\frac {1}{2}$ 0 < δ < 1 2 for solutions of the dynamic programming principle $$ \begin{array}{@{}rcl@{}} u^{\varepsilon} (x) = \sum\limits_{j=1}^{n} \alpha_{j} \underset{\dim(S)=j}{\inf} \underset{|v|=1}{\underset{v\in S}{\sup}} \frac{u^{\varepsilon} (x + \varepsilon v) + u^{\varepsilon} (x - \varepsilon v)}{2} \end{array} $$ u ε ( x ) = ∑ j = 1 n α j inf dim ( S ) = j sup v ∈ S | v | = 1 u ε ( x + ε v ) + u ε ( x − ε v ) 2 with α1,αn > 0 and α2,⋯ ,αn− 1 ≥ 0. The proof is based on a new coupling idea from game theory. As an application, we get the same regularity estimate for viscosity solutions of the PDE $…

Negative emotional state modulates visual working memory in the late consolidation phase

2020

Although a considerable literature has grown up around the interactions between emotional state and visual working memory (VWM) performance, the mechanism underlying the impact of the negative emotional state on VWM remains unclear. The present study aimed to test whether the influence of emotional state is related to the early phase or late phase of VWM consolidation process. Across three experiments, we found that the negative emotional state did not affect VWM performance when the presentation time of stimuli was short. However, when the presentation time was long, the negative emotional state increased the VWM precision and reduced the VWM number. According to the two-phase model propos…

Oikealle alalle? : logistiikka-alan ammattikoulutuksen ja työelämän osaamisen todellisuuksien kohtaaminen

2016

The aim of this doctoral thesis was to study how vocational education and training (VET) and working life encounter each other. Naturally the research topic chosen was selected from the researcher´s own professional field, i.e., logistics education. The research task was to examine, how VET-students' professional expectations in the study field of logistics encounter with the working life realities. The main research question was “How do the logistics (driver training) students’ vocational expectations encounter with the requirements of dynamically changing working life from the point of view of the vocational competence, the time span of 2001-2025?” The two sub-questions were 1) How do the…

Voluntary Private Investments Role in Pension System in Latvia

2021

Pension systems have become one of the main priorities for the national governments. Developed countries population is getting older by putting the pressure on the state budgets and work age people tax load. The current pension system in Latvia performs according to regulation of state compulsory unfunded pension scheme since 1996 and regulation of the state funded or accumulated pension scheme since 2001. The third pension system pillar is private voluntary pension schemes realized in form of people contributions into pension funds and life insurance policies. Aim of the research – deeper analyses of voluntary private investments as the pension system part and its development challenges in…

El consumidor especialmente vulnerable: de la protección class-based a la protección state-based

2022

El presente estudio centra su atención en la regulación, desde un punto de vista sustantivo, de la figura del consumidor especialmente vulnerable y de su protección. El legislador español ha querido dar un paso adelante mediante la introducción de dicha figura en el Texto Refundido de la Ley General para la Defensa de los Consumidores y Usuarios (TRLGDCU). Así, la opción escogida ha sido la de incorporar un concepto dinámico del consumidor vulnerable (protección “state-based”), alejado de la concepción tradicional caracterizada por una perspectiva basada exclusivamente en las características individuales (protección “class-based”), que no consideraba factores externos relativos a la situaci…

Measuring Vulnerability of Asylum Seekers and Refugees in Italy

2019

In recent years, a growing number of forced migrants have travelled to Italy across the Mediterranean Sea. While the number of new arrivals has diminished since 2017, the Italian reception system still struggles to process the high number of applications for international protection. A significant proportion of forced migrants who arrive in Italy end up living in informal settlements, such as occupied buildings, shacks, containers and tented camps. In this study, we assess the vulnerability of asylum seekers and refugees living in informal settlements in Italy, using data from the first nationally representative survey of this population. We compare a count measure of vulnerability with a n…
