Pre-expanded Anterolateral Thigh Perforator Flap for Phalloplasty.
2016
The anterolateral thigh (ALT) perforator flap for phalloplasty is gaining popularity because it avoids the well-known scars of the radial forearm flap. However, scars are not eliminated, just moved to a different location, the thigh, that can for some patients be of great sexual value. Preexpansion of the ALT flap allows primary donor site closure, thus avoiding not only the unsightly appearance of a skin grafted ALT donor site, but also the skin graft donor site scar. Preoperative perforator location by means of computed tomography angiography allows safe expander placement through 2 small remote incisions.
Bader's analysis of the electron density in the Pbca enstatite - Pbcn protoenstatite phase transition
2011
The Bader’s topological analysis of the electron density obtained via ab initio quantum mechanical simulation at Hartree–Fock and DFT level has been performed for experimentally in situ heated structures of enstatite–protoenstatite MgSiO 3 . The measurements have been performed in the temperature range 1200–1400 K. The work was aimed at characterizing both the evolution of the electron arrangement in the crystal and that of the crystal-structure at the enstatite–protoenstatite phase transition in terms of topology of the electron density, with particular care about the Mg–O and the O–O bonds. The observed breaking of some chemical bonds with increasing temperature and/or due to the phase tr…
Artificial Suffering: An Argument for a Global Moratorium on Synthetic Phenomenology
2021
This paper has a critical and a constructive part. The first part formulates a political demand, based on ethical considerations: Until 2050, there should be a global moratorium on synthetic phenomenology, strictly banning all research that directly aims at or knowingly risks the emergence of artificial consciousness on post-biotic carrier systems. The second part lays the first conceptual foundations for an open-ended process with the aim of gradually refining the original moratorium, tying it to an ever more fine-grained, rational, evidence-based, and hopefully ethically convincing set of constraints. The systematic research program defined by this process could lead to an incremental re…
Constructive role of non-adiabaticity for quantized charge pumping
2010
We investigate a recently developed scheme for quantized charge pumping based on single-parameter modulation. The device was realized in an AlGaAl-GaAs gated nanowire. It has been shown theoretically that non-adiabaticity is fundamentally required to realize single-parameter pumping, while in previous multi-parameter pumping schemes it caused unwanted and less controllable currents. In this paper we demonstrate experimentally the constructive and destructive role of non-adiabaticity by analysing the pumping current over a broad frequency range.
A new constructive method using the theory of invariants to obtain material behavior laws
2006
International audience; The aim of this paper is to present a constructive method to derive mechanical behavior laws using the Theory of Invariants and Continuum Thermodynamics. More precisely, we want to construct, in a general way, the state or dissipation potential in a polynomial form given a set of variables V and the material symmetry group S. For this purpose, we show how to obtain a set of generators for the S-invariant polynomials of V. Then, using the Grœbner basis concept, we write all the decompositions of a polynomial of a given degree.
Measuring International Competitiveness of Romania by Using Porter's Diamond and Revealed Comparative Advantage
2013
Abstract International competitiveness generate a number of challenges because creates profitability for companies, welfare for citizens, sustainable prosperity for the economy as long as it is perceived as a constructive concept. The aim of present paper is to identify the international competitiveness of Romania by analyze the competitive advantage and disadvantage according to Porter‘s Diamond, on one hand, and by calculate revealed comparative advantage according to Balasa, on the other hand. The results show that Romanian has more competitive disadvantage than competitive advantage, even if by comparison with European Union, Romania has some revealed comparative advantage.
Method Framework for Developing Enterprise Architecture Security Principles
2019
Organizations need to consider many facets of information security in their daily operations – among others, the rapidly increasing use of IT, emerging technologies and digitalization of organizations’ core resources provoke new threats that can be difficult to anticipate. It has been argued that the security and privacy considerations should be embedded in all the areas of organizational activities instead of only relying technical security mechanisms provided by the underlying systems and software. Enterprise Architecture Management (EAM) offers a holistic approach for managing different dimensions of an organization, and can be conceived as a coherent and consistent set of principles tha…
Complement proteins regulating macrophage polarisation on biomaterials
2019
[EN] One of the events occurring when a biomaterial is implanted in an host is the protein deposition onto its surface, which might regulate cell responses. When a biomaterial displays a compromised biocompatibility, distinct complement pathways can be activated to produce a foreign body reaction. In this article, we have designed different types of biomaterial surfaces to study the inflammation process. Here, we used different concentrations of (3-glycidoxypropyl)-trimethoxysilane (GPTMS), an organically-modified alkoxysilane as a precursor for the synthesis of various types of sol-gel materials functionalizing coatings for titanium implants to regulate biological responses. Our results sh…
A Constructive Arboricity Approximation Scheme
2020
The arboricity \(\varGamma \) of a graph is the minimum number of forests its edge set can be partitioned into. Previous approximation schemes were nonconstructive, i.e., they approximate the arboricity as a value without computing a corresponding forest partition. This is because they operate on pseudoforest partitions or the dual problem of finding dense subgraphs.
Descubriendo las Fortalezas y Construcción de Resiliencia con Terapia Cognitiva: Un Modelo en 4 pasos
2009
The next frontier in cognitive behavioral therapy is learning how to foster development of positive human qualities. Development of positive qualities requires somewhat different therapy methods than repair of problems. More fundamentally, building positive qualities sometimes requires therapists to adopt a different therapy lens and philosophy. This approach integrates knowledge from positive psychology and resilience research, traditional cognitive therapy methods, and constructive cognitive therapy approaches. Resilient people have skills to help them face and handle positive and negative life events so they are less likely to develop psychological difficulties. Resilience helps people p…
