This paper presents a highly linear receiver frontend operating from 700 MHz to 3.7 GHz with 3rd order harmonic rejection. It consists of a complementary low noise transconductance amplifier with capacitive cross coupling and negative gm current sources, a six phase current-mode passive mixer, and baseband transimpedance amplifiers providing programmable gain. The circuit has been fabricated in 65
We explore the phenomenology of a unique three-Higgs-doublet model based on the single CP symmetry of order 4 (CP4) without any accidental symmetries. The CP4 symmetry is imposed on the scalar potential and Yukawa interactions, strongly shaping both sectors of the model and leading to a very characteristic phenomenology. The scalar sector is analyzed in detail, and in the Yukawa sector we list all
Colloidal dispersions of anisometric particles can display dynamical arrest and ordering involving both translational and rotational degrees of freedom. We show that orientational order can develop in glassy colloidal dispersions of charged platelets when a concentration gradient is imposed through solvent evaporation. Our model system of Laponite (LRD) platelets in deionized water has been extens
In the present paper, linear substructures with nonlinearities localized at their interfaces, such as the joints in a beam structure, are studied. By subdivision of the total structure into substructures, reduced subsystems are obtained by component mode synthesis. Nonlinear elements are introduced at supports or between substructures. A numerical example is presented where a beam subjected to bla
Most current results on coverage control using mobile sensors require that one partitioned cell is associated with precisely one sensor. In this paper, we consider a class of coverage control problems involving higher order Voronoi partitions, motivated by applications where more than one sensor is required to monitor and cover one cell. Such applications are frequent in scenarios requiring the se
According to the curriculum of the preschool, one of it's purposes is to work with equality, and to challenge traditional gender roles. Despite this, many preschools still lack active work with gender/equality – the difference amongst pre-schools is sometimes extreme. I tried to find elements that influence preschool teachers to choose to work with gender and equality. Some of these elements a

This paper analyses the effects of emigration on unemployment and wages in the ten Central and Eastern European countries that joined the EU in 2004 and 2007. These countries experi-enced large migration outflows following their accession and thus lost a considerable share of their labour force. This presents a good natural experiment to study the impact of emigration on the labour market outcomes
This study examined differences between sport-specific and general eating behaviours in recreational athletes and investigated whether injury severity, athletic identity, and conformity to masculine norms predicted eating-related outcomes following sport injury. The original sample consisted of N = 161 recreational athletes; however, after applying the exclusion criteria and including only injured

Limitations on the scattering matrix are derived for a wide class of objects, restricting their broadband interaction with electromagnetic vector spherical waves in terms of their size, shape and static material properties. In particular, it is seen that the order of the dominating term for electrically small objects increases with the order of the spherical wave. The results are applicable to man
Low-complex and low power non-coherent energy detector (ED) is interesting for low data rate impulse radio (IR) ultra wideband (UWB) systems but, compared to coherent receivers, it suffers from a loss in performance due to low signal-to-noise ratio (SNR) at the detector. In addition, the performance of an ED strongly depends on the integration interval (window size) of the integrator and the window
The change in constituent order in English is one of the most thoroughly investigated changes in the history of the English language. Even so, there is still disagreement among scholars as to what caused the change. The aim of this article is to argue that it was the influence of the Scandinavians and their language, Old Norse, that caused English to abandon the SOV constituent order and instead a

Background: Uncertainty is inevitable in clinical practice in primary care and tolerance for uncertainty and concern for bad outcomes has been shown to vary between physicians. Uncertainty is a factor for inappropriate antibiotic prescribing. Evidence-based guidelines as well as near-patient tests are suggested tools to decrease uncertainty in the management of patients with respiratory tract infe
