Microscopic origin of the charge transfer in single crystals based on thiophene derivatives : A combined NEXAFS and density functional theory approach
We have investigated the charge transfer mechanism in single crystals of DTBDT-TCNQ and DTBDT-F4TCNQ (where DTBDT is dithieno[2,3-d;2′,3′-d′] benzo[1,2-b;4,5-b′]dithiophene) using a combination of near-edge X-ray absorption spectroscopy (NEXAFS) and density functional theory calculations (DFT) including final state effects beyond the sudden state approximation. In particular, we find that a descri
Market Structure and Rating Strategies in Credit Rating Markets : A Dynamic Model with Matching of Heterogeneous Bond Issuers and Rating Agencies
This paper investigates the impact of rating agencies in a market with asymmetric information. In particular, the role of credit rating agencies as an intermediary between investors and bond issuers is discussed. We model this setting in a dynamic framework in which both rating agencies and bond issuers are of heterogeneous quality. Rating agencies can apply costly research technology to reveal th
Prices, debt and market structure in an agent-based model of the financial market
We develop an agent-based model in which heterogeneous and boundedly rational agents interact by trading a risky asset at an endogenously set price. Agents are endowed with balance sheets comprising the risky asset as well as cash on the asset side and equity capital as well as debt on the liabilities side. A number of findings emerge when simulating the model: we find that the empirically observa
News Reaction in Financial Markets within a Behavioral Finance Model with Heterogeneous Agents
This paper presents a Heterogeneous Agent Model of a financial market with chartist and fundamentalist traders that exhibit bounded rationality and short-term thinking to explain the effect of under and overreaction to news. The existence of the Market Maker’s finite price adjustment speed and the presence of risk aversion lead to the fact that prices do not adjust instantaneously to new informati

The perception of the poor: Capturing stereotype content with different measures
Even though Sweden stands out in many ways, with for example a well-developed welfare system, there are some indications that Swedish egalitarianism does not include tolerance for people with low income. The present research concerns the content of the Swedish stereotype of poor people, and examines whether the poor are associated with just as negative traits as they are in other countries.

Thermopower signatures and spectroscopy of the canyon of conductance suppression
Interference effects in quantum dots between different transport channels can lead to a strong suppression of conductance, which cuts like a canyon through the common conductance plot [Phys. Rev. Lett. 104, 186804 (2010)PRLTAO0031-900710.1103/PhysRevLett.104.186804]. In the present work we consider the thermoelectric transport properties of the canyon of conductance suppression using the second-or
Approach for process innovative design based on SOA
Solving process problem needs the support of method and knowledge. To organize relative resources in accordance with requirement, an innovative process design service model based on service-oriented architecture was proposed. Strategy service and knowledge service were built from the dimensions of knowledge, method and computer aided tool. The ontology of services was built, and the system archite
Nonlinear thermoelectric efficiency of superlattice-structured nanowires
We theoretically investigate nonlinear ballistic thermoelectric transport in a superlattice-structured nanowire. By a special choice of nonuniform widths of the superlattice barriers - analogous to antireflection coating in optical systems - it is possible to achieve a transmission which comes close to a square profile as a function of energy. We calculate the low-temperature output power and powe
Road Safety Management – The need for a systematic approach
In order to achieve significant improvements in road safety at the national level, there is a need for a systematic approach to road safety management with clear responsibilities and accountability. In this paper – after a review of the literature on guidelines, recommendations and research findings – twelve essential elements of such a systematic approach is pointed out, and corresponding relevanIn order to achieve significant improvements in road safety at the national level, there is a need for a systematic approach to road safety management with clear responsibilities and accountability.

Negative feedback enables structurally signed steady-state influences in artificial biomolecular networks
We examine the capacity of artificial biomolecular networks to respond to perturbations with structurally signed steady-state changes. We consider network architectures designed to balance their output production as a function of downstream demand: the species producing the output, called a source, up- or down-regulates its production rate as a function of the demand. Using an exact algorithm we s
A saturated strategy robustly ensures stability of the cooperative equilibrium for Prisoner's dilemma
We study diffusion of cooperation in a two-population game in continuous time. At each instant, the game involves two random individuals, one from each population. The game has the structure of a Prisoner's dilemma where each player can choose either to cooperate (c) or to defect (d), and is reframed within the field of approachability in two-player repeated game with vector payoffs. We turn the g
A programmable baseband processor for massive MIMO uplink multi-user detection
Massive MIMO is a promising technology for the coming 5G wireless systems. In this paper, a programmable baseband processor specifically designed for uplink symbol detection targeting massive MIMO is presented with a novel matrix inversion method proposed to obtain more precise and efficient computation. Including a microcode controlled channel preprocessing unit and a pipelined detection unit, th
A convex optimization approach to cancer treatment to address tumor heterogeneity and imperfect drug penetration in physiological compartments
The clinical success of targeted cancer therapies is limited by the emergence of drug resistance often due to pre-existing tumor genetic heterogeneity and acquired, therapy-induced resistance. Targeted therapies have varied success in addressing metastatic disease, due to their ability to penetrate certain physiological compartments. This paper considers an evolutionary cancer model that incorpora
Asymmetries : Conceptualizing Environmental Inequalities as Ecological Debt and Ecologically Unequal Exchange
I centrum för denna sammanläggningsavhandling, som består av sex artiklar och ett introduktionskapitel, står koncepten ekologisk skuld, klimatskuld, ekologiskt ojämnt utbyte och ojämn appropriering av kolsänkor. Begreppens idéhistoria och politiska historia spåras bakåt till miljörättviserörelsen, ekologisk ekonomi och neo-marxistisk ekonomi. De utvecklas konceptuellt och länkas samman analytiskt In this compilation thesis, consisting of six papers and an introductory chapter, the concepts of ecological debt, climate debt, ecologically unequal exchange, and unequal carbon sink appropriation are at the centre. Their intellectual and political histories are traced to environmental justice movements, ecological economics and neo-Marxist economics. They are developed conceptually and linked to
Neighboring genes for DNA-binding proteins rescue male sterility in Drosophila hybrids
Crosses between closely related animal species often result in male hybrids that are sterile, and the molecular and functional basis of genetic factors for hybrid male sterility is of great interest. Here, we report a molecular and functional analysis of HMS1, a region of 9.2 kb in chromosome 3 of Drosophila mauritiana, which results in virtually complete hybrid male sterility when homozygous in t

Circuits and systems for 5G network : Massive MIMO and advanced coding
This paper serves as an overview to the special session Circuits and Systems for 5G on IEEE International Conference on ASIC (ASICON) 2015. More specifically, we introduce two of enabling technologies for the coming 5G wireless era, namely massive multiple-input multiple-output (MIMO) technique and advanced coding techniques such as polar codes. Massive MIMO is a relatively new wireless communicat
