The multimedia era has started. The migration of computer (packet oriented) and telephony (circuit switched) networks in combination with an explosive development of new services, creates a mass market for public broadband communication. There are no reasons foreseen why these kinds of services should not go mobile. Future customers will not treat a mobile access differently than a fixed access to
Reactive settling is the process of sedimentation of small solid particles in a fluid with simultaneous reactions between the components of the solid and liquid phases. This process is important in sequencing batch reactors (SBRs) in wastewater treatment plants. In that application the particles are biomass (bacteria; activated sludge) and the liquid contains substrates (nitrogen, phosphorus) to b
Tunnel FETs (TFETs) have been identified as the most promising steep slope devices for ultralow power logic circuits. In this paper, we demonstrate in-plane InAs/Si TFETs monolithically integrated on Si, using our recently developed template-assisted selective epitaxy approach. These devices represent some of the most scaled TFETs with dimensions of less than 30 nm, combined with excellent aggrega
Background: Unexpected prolongation of first-line coagulation tests, including activated partial thromboplastin time (APTT), should trigger further work-up by performing mixing tests to elucidate the underlying cause, direct further specific testing and clarify their possible clinical impact. The aim of our study was to assess whether methodological diversity has any impact on the APTT mixing test
A memetic framework for optimal inverse design is proposed by combining a local gradient-based procedure and a robust global scheme. The procedure is based on method-of-moments matrices and does not demand full inversion of a system matrix. Fundamental bounds are evaluated for all optimized metrics in the same manner, providing natural stopping criteria and quality measures for realized devices. C
The purpose of this study was to illustrate how children of the "digital generation" used their computers in their everyday practice. The important in the study was children's perspective on computers interactions and communications in a digital arena. An essential item about understanding children's way to think about computers was to let children themselves speak by taking par
Eye tracking technology has become increasingly prevalent in scientific research, offering unique insights into oculomotor and cognitive processes. The present article explores the relationship between scientific theory, the research question, and the use of eye-tracking technology. It aims to guide readers in determining if eye tracking is suitable for their studies and how to formulate relevant
PREVENTIVE VACCINATION IS SUCCESSFULLY PRACTISED TODAY AGAINST TWO NEOPLASTIC DISEASES OF DOMESTIC ANIMALS: fibropapillomatosis of cattle and Marek's disease of chickens (a lymphoproliferative disease). Also it may soon be possible to immunize cats against lymphosarcoma. This memorandum describes these diseases and the immunological reactions involved. It also mentions a number of other tumours th
A series of twelve full scale experiments with upholstered furniture and beds has been carried out. Ten experiments were performed inside an extensively equipped compartment with a door opening. In order to study the influence of the room on the fire development two experiments were carried out in the open outside the compartment. One experiment in the room was made with restricted ventilation sim

We present a data-driven method, based on extended structure tensors, that interpolates multicomponent, marine seismic data. The method is designed to interpolate pressure measurements and their normal derivatives using directional information from the crossline derivative of the pressure field.
This issue of Leadership marks our first full year as Co-Editors-in-Chief. As we highlighted in our introductory editorial (Edwards and Schedlitzki, 2023) we see our role as striving to develop the community of the journal in its endeavour to be a key, critical and contemporary voice for leadership studies. To continue this journey, and to help contributors frame and develop their work for submiss

Albumin concentration in a morning urine sample was analyzed in a cross-sectional study in 476 insulin-dependent diabetic patients. The following groups of patients were defined: A) normal urinary albumin (urine albumin less than 12.5 mg/L); B) high normal albuminuria (12.5-30 mg/L); C) microalbuminuria, ie, incipient nephropathy (31-299 mg/L); and D) clinical nephropathy (greater than or equal to
For magnetic resonance imaging (MRI) of non-traumatic brachial plexus (BP) lesions, sequences with contrast injection should be considered in the differentiation between tumors, infection, postoperative conditions, and post-radiation changes. The most common non-traumatic inflammatory BP neuropathy is radiation neuropathy. T2-weighted images may help to distinguish neoplastic infiltration showing
Background: Fine-needle aspiration biopsy (FNAB) of lymph nodes is a widely used method for evaluating lymphadenopathy. FNAB offers general advantages of rapid turnaround time, low cost and minimal morbidity, and more specific advantages in various clinical situations, such as deeply located lymph nodes or patients with significant comorbidities. The FNAB sample can be utilized for a wide range of
The CO2 source and sink distribution across Europe can be estimated in principle through inverse methods by combining CO2 observations and atmospheric transport models. Uncertainties of such estimates are mainly due to insufficient spatiotemporal coverage of CO2 observations and biases of the models. In order to assess the biases related to the use of different models the CO2 concentration field o
We present a comparison of chemistry-transport models (TransCom-N2O) to examine the importance of atmospheric transport and surface fluxes on the variability of N2O mixing ratios in the troposphere. Six different models and two model variants participated in the inter-comparison and simulations were made for the period 2006 to 2009. In addition to N2O, simulations of CFC-12 and SF6 were made by a
Diversity in the genetic profile between individuals and specific ethnic groups affects nutrient requirements, metabolism and response to nutritional and dietary interventions. Indeed, individuals respond differently to lifestyle interventions (diet, physical activity, smoking, etc.). The sequencing of the human genome and subsequent increased knowledge regarding human genetic variation is contrib
