In search of building types : On visitor centers, thresholds and the territorialisation of entrances

The aim of this paper is to contribute to an actantial approach to building type studies through a study of the visitor centre and its role in contemporary spatial production. The article takes its empirical departure in the (from a Swedish perspective) intense urbanization of the Scania region, in the southern part of Sweden. Looking at building types in terms of actants implies that different se

A three bit second order audio band delta sigma modulator with 98.2dB SQNR

A three bit second order delta sigma modulator for audio applications implemented in 130nm CMOS technology is presented. The modulator features two integrators, a flash quantizer and two current steering DACs. In order to minimize the effect of delays in the DACs, excessive loop delay (ELD) compensation is utilized. Using an oversampling ratio (OSR) of 80, the design consumes 2.8mW and achieves a

High Estrogen Receptor β Expression Is Prognostic among Adjuvant Chemotherapy-Treated Patients-Results from a Population-Based Breast Cancer Cohort

PURPOSE: Isoform-specific tumor estrogen receptor β (ERβ) expression may hold prognostic information in breast cancer, especially among endocrine-treated breast cancer patients. The study's purpose was to evaluate ERβ isoform 1 (ERβ1) expression in relation to tumor characteristics, ESR2 genotypes, and prognosis in different treatment groups.EXPERIMENTAL DESIGN: A population-based prospective coho

Analog Integrated Audio Frequency Synthesizer

In this paper we present an audio synthesizer that creates audio signals, intended to be reproduced as sound by a loudspeaker. This paper details the design, implementation and verification of an analog, subtractive audio synthesizer. The synthesizer produces a variety of waveforms spanning approximately 3 octaves. The frequency is controlled by an external voltage and the harmonic content is regu

Correlating structure and electronic band-edge properties in organolead halide perovskites nanoparticles

After having emerged as primary contenders in the race for highly efficient optoelectronics materials, organolead halide perovskites (OHLP) are now being investigated in the nanoscale regime as promising building blocks with unique properties. For example, unlike their bulk counterpart, quantum dots of OHLP are brightly luminescent, owing to large exciton binding energies that cannot be rationaliz

Two-photon double ionization of neon using an intense attosecond pulse train

We present a demonstration of two-photon double ionization of neon using an intense extreme ultraviolet (XUV) attosecond pulse train (APT) in a photon energy regime where both direct and sequential mechanisms are allowed. For an APT generated through high-order harmonic generation (HHG) in argon we achieve a total pulse energy close to 1μJ, a central energy of 35 eV, and a total bandwidth of ∼30 e

Crisis Communication in China: A Social Constructionist Approach

Crisis communication is a field dominated by functionalist and objectivist perspectives even though there are exceptions. With a departure in an alternative epistemology – social construc-tionism – this paper provides a reflective approach to understand crisis communication as a contextual and cultural construction process. Focusing on the social construction of crisis brings a much-needed approac

Increased deposition of glycosaminoglycans and altered structure of heparan sulfate in idiopathic pulmonary fibrosis

Idiopathic pulmonary fibrosis (IPF) is characterized by aberrant deposition of extracellular matrix (ECM) constituents, including glycosaminoglycans (GAGs), that may play a role in remodelling processes by influencing critical mediators such as growth factors. We hypothesize that GAGs may be altered in IPF and that this contribute to create a pro-fibrotic environment. The aim of this study was the
