Non-radiative decay of core excitations at the B 1s and N 1s absorption edges of bulk hexagonal boron nitride (h-BN) has been studied with resonant Auger spectroscopy. In order to reproduce the bulk properties of the sample while keeping it electrically conducting, we have grown reasonably thick (more than 20nm) polycrystalline films of h-BN on a Ni(111) surface by thermal cracking of borazine vap
Intellectual capital has gained increasing attention concerning both research and more practically oriented applications during the past five years. Intellectual Capital and other knowledge management tools are topics that have emerged in the light of a broader trend of redirecting the foundation of competitive advantage from the company’s tangible assets to its intangibles such as knowledge base,
The globalization of English in Sweden is examined as it takes shape in educational policy and practice. Following in the tradition of a “new wave” of language policy and planning research that emphasizes connections between policy and how it is interpreted by local stakeholders, this investigation focuses on textual data from Swedish national curricular documents and observational data of preserv
The minimum weighted edge dominating set problem (MWEDS) generalizes both the weighted vertex cover problem and the problem of covering the edges of graph by a minimum cost set of both vertices and edges. In this paper, we propose a meta heuristic approach based on genetic algorithm and local search to solve the MWEDS problem. Therefore, the proposed method is considered as a memetic search algori
The recently launched IEA SHC Task 61 aims at fostering the integration of daylighting and electric lighting solutions for the benefit of higher user satisfaction and energy savings at the same time. In order to drastically reduce the energy use of buildings daylighting, electric lighting and associated controls must be integrated, and the role of the user should be considered in the integration p
The home has a self-evident place within audience studies. In spite of this salient position, the home has seldom been theoretically problematized; it has often been ‘reduced’ to a social context of the prioritized media engagement (domestication research is partly an exception). The paper is further justified by the fact that media and media practices are important for the home and its boundaries
Background:For software-intensive organizations, Open Source Software (OSS) may provide a pivotal building block in business models and strategies, product and service offerings, as well as in tool and infrastructure setups. The Requirements Engineering (RE) and development processes of OSS take place inside communities where the focal organization is a stakeholder among many, including competitor
This work presents a digital calibration technique in continuous-time (CT) ΔΣ analog to digital (A/D) converters. The converter is clocked at 144MHz with a low oversampling ratio (OSR) of only 8. Dynamic element matching (DEM) is not efficient to linearize the digital to analog converter (DAC) when the OSR is very low. Therefore, non-idealities in the outermost multi-bit feedback DAC are measured
We carry out bipolar Monte Carlo (MC) simulations of electron and hole transport in a multi-quantum well light-emitting diode with an electron-blocking layer. The MC simulation accounts for the most important interband recombination and intraband scattering processes and solves self-consistently for the non-quasiequilibrium transport. The fully bipolar MC simulator results in better convergence th
We report an alternative pathway for p-type InP nanowire (NW) doping by diffusion of Zn species from the gas phase. The diffusion of Zn was performed in a MOVPE reactor at 350–500 °C for 5–20 min with either H2 environment or additional phosphorus in the atmosphere. In addition, Zn3P2 shells were studied as protective caps during post-diffusion annealing. This post-diffusion annealing was performe
In the contemporary dual crisis, economic crisis policies cannot be dealt with in isolation from the rampant and acute ecological crisis – and vice versa. In this article, we challenge the hegemonic positions in purported attempts to solve the crises so far: in the economic realm, the Keynesian episode of 2008–2009 as well as austerity policies, and with regard to the ecological crisis, ecologicalIn the contemporary dual crisis, economic crisis policies cannot be dealt with in isolation from the rampant and acute ecological crisis – and vice versa.

Early perceptual grouping was studied using 256-channels event-related potentials in a choice response task. The task involved the detection of a triangle configuration of Gabor patches among patches of different spatial frequencies. The influence of two task-irrelevant factors was compared. One was the spatial proximity relation between the target patches and the other their relative orientation,
In a recent article we presented a model for hadronic rescattering, and some results were shown for pp collisions at LHC energies. In order to extend the studies to pA and AA collisions, the Angantyr model for heavy-ion collisions is taken as the starting point. Both these models are implemented within the general-purpose Monte Carlo event generator Pythia, which makes the matching reasonably stra
Partially premixed combustion is a compression ignited combustion strategy where high exhaust gas recirculation (EGR) levels in combination with early or late injection timing result in a prolonged ignition delay yielding a more premixed charge than with conventional diesel combustion. With this concept it is possible to get low smoke and NOx emissions simultaneously. Accurate control of injection
In this paper, we discuss the exclusive photoproduction of ground and excited states of ψ(1S,2S) and ϒ(1S,2S) in ultraperipheral collisions (UPCs). Using the potential model in order to obtain the vector meson wave function, we find a good agreement of our calculations with data from the LHC and HERA colliders for J/ψ(1S,2S) and ϒ(1S) in γp collisions. We extend the calculations to the nuclear tar
