Simultaneous readout of two charge qubits

2006

We consider a system of two solid state charge qubits, coupled to a single read-out device, consisting of a single-electron transistor (SET). The conductance of each tunnel junction is influenced by its neighboring qubit, and thus the current through the transistor is determined by the qubits' state. The full counting statistics of the electrons passing the transistor is calculated, and we discuss qubit dephasing, as well as the quantum efficiency of the readout. The current measurement is then compared to readout using real-time detection of the SET island's charge state. For the latter method we show that the quantum efficiency is always unity. Comparing the two methods a simple geometric…

The refugee entrepreneurship process from/in emerging economies

2021

The paper examines several refugee experiences in Mexico and presents their reasons for leaving their home countries. A gap in research is identifying the entrepreneurial process experienced by refugee entrepreneurs. We use the case study of 10 Latin American refugees in Mexico to propose a conceptual framework that describes the entrepreneurial process of refugee entrepreneurs. We have found that this process begins with the abandonment of the country of origin, followed by the traumatic experiences that caused flight and the difficulties they face in the pilgrimage to the host country. These events help shape the entrepreneurial intention of the refugees.

Innovative and Sustainable Food Business Models

2019

Companies are called upon to solve the great challenges of the new millennium. The food sector, from this point of view, plays a strategic role. Poverty, malnutrition, hunger, climate change, and social inequalities are just some of the trends which the agri-food sector has to cope with. The digital transformation that companies will need to embrace to survive requires new ways of creating, thinking, and working with technology-driven tools to provide value for their businesses and customers. Digitization, whether it pertains to new technologies, the analysis of big data or the development of on-line and spatial applications, can contribute to achieving systemic food production transformati…

Assessment of methodologies and data used to calculate desalination costs

2017

Abstract In desalination, similarly with other industries, the cost of the final product is one of the most important criteria that define the commercial success of a specific technology. Therefore, when new projects are planned or new technologies are proposed, the analysis of the expected costs attracts a lot of attention and is compared to (perceived) costs of state-of-the-art desalination or costs of alternative fresh water supply options. This comparison only makes sense if the cost assessment methodologies are based on the same principles and use common assumptions. This paper assesses: (i) the methodologies used to calculate the water cost; (ii) the boundary conditions and (iii) the …

Polymer‐Based Composites for Engineering Organic Memristive Devices

2022

Memristive materials are related to neuromorphic applications as they can combine information processing with memory storage in a single computational element, just as biological neurons. Many of these bioinspired materials emulate the characteristics of memory and learning processes that happen in the brain. In this work, we report the memristive properties of a two-terminal (2-T) organic device based on ionic migration mediated by an ion-transport polymer. The material possesses unique memristive properties: it is reversibly switchable, shows tens of conductive states, presents Hebbian learning demonstrated by spiking time dependent plasticity (STDP), and behaves with both short- (STM) an…

Sustainable urban transport policy in emerging countries – case study of Mexico

2015

Negatywne efekty zewnętrzne transportu stanowią bolączkę współczesnych miast, niekorzystnie oddziałując na procesy rozwoju społeczno-gospodarczego. Problemy te są widoczne nie tylko w krajach wysoko czy średnio rozwiniętych – w ogromnym stopniu borykają się z nimi wielomilionowe i wielkopowierzchniowe metropolie, które z kolei są charakterystyczne głównie dla krajów wschodzących, jak np. Chiny, Indie, Brazylia czy Meksyk. Celem artykułu jest przedstawienie wybranych aspektów polityki zrównoważonego rozwoju transportu w stolicy jednego z tych krajów – Meksyku. Autorka starała się również odpowiedzieć na pytanie, w jaki sposób specyficzne uwarunkowania lokalne o różnym charakterze determinują…

The BioS4You European project: An innovative way to effectively engage Z-generation students in STEM disciplines

2021

In this contribution, we present the BioS4You project and analyse the results obtained in the first 18 months of its activity. The “Bio-Inspired STEM topics for engaging young generations” (BioS4You) Erasmus+ KA2 Innovation project aims to bridge the gap between STEM national curricula (which include Science, Technology, Engineering, and Mathematics) and the needs of Z-generation students, uninterested to basic themes, but enthusiastic in issues related to environmental, social, and health concerns. The BioS4You project engages young learners in STEM subjects, starting with current issues of interest for them, as the social and environmental impact of new technologies, connecting STEM conce…

Availability of alternative financial resources for SMES as a critical part of the entrepreneurial eco-system: Latvia and Italy

2015

Abstract The importance of non-traditional alternative/innovative financing is gaining recognition in both developed and emerging economies throughout the world (OECD, 2012; EC, 2013; ECB, 2013; ECB, 2014). SME financing in Europe remains primarily bank based, in spite of the many policies proposed to develop alternative financing instruments (e.g. adopting directives on venture capital, improving the transparency and visibility of SMEs on capital markets, etc.) The paper aims at understanding the availability of alternative resources for SMEs by analyzing them rigorously, understanding the obstacles for the development of non-bank finance and developing recommendations to overcome them. Th…
