A 20-GHz Bandwidth Power Amplifier for Phased Array 5G New Radio Transmitters
A 27-47-GHz differential cascode power amplifier for millimeter-wave 5G new radio applications is presented. The PA is a three-stage design using inductively coupled impedance transformers with 31-dB nominal power gain. A device periphery ratio of 1:2:6 is adopted for predriver, driver, and final stage, respectively. A gain equalization technique was used in the interstage transformers to obtain t
Primum non nocere; the importance of evaluating the effect of treatment and considering side effects
The typical traffic accident in lithuania in comparison with Sweden
Every day we strive to improve the environment and make it as comfortable as possible, creating new products and new technologies that are literally changing people’s lives. Transport is one of the most important engines of development in the world and, unfortunately, it is one of the most painful taking into account how many people’s lives we are losing in it. Ensuring safe traffic, stabilizing a
X-ray holography
With the dramatic increase in x-ray source brilliance and associated coherent photon flux, holography with x-rays has become feasible and is increasingly used for real-space investigations of static and dynamic properties of nanoscale systems. We describe the basic principles and capabilities of the method and present the current state of the art. A particular emphasis is put on the investigation
Fashioning femininity in the 1840s : Charlotte Brontë and Villette
This chapter charts the ways in which Charlotte Brontë uses sartorial details to fashion and re-fashion a possible model of femininity in her last novel, Villette. The protagonist Lucy Snowe, a young woman in her mid-twenties, is situated in between, on the one hand, two teenage girls and, on the other hand, two middle-aged women, who between them represent four different models of fashionable fem
State measurements of benefit fraud : Why expert elicitations cannot be used to measure incorrect personal assistance payments
During the last decade, personal assistance programs have suffered from cutbacks, resulting in a public debate about the future of the service. This debate has largely been framed by public commission estimations of the level of incorrect personal assistance payments, where the idea that circa 10% of all assistance payments are incorrect repeatedly has been used to justify measures designed to dec
Hand strength and dexterity in individuals with hand eczema
Background: Patients with hand eczema often describe symptoms such as pain, clumsiness and difficulty flexing their fingers, thus impairing the function of the hand. Objective: The aim of this study was to investigate whether hand eczema is associated with a measurable impairment of hand strength and dexterity. We also studied the relationship between hand function and the ability to perform activ
Waders flying with folded legs – which species, when, where and why?
Waders normally fly with their legs stretched out under the tail, with their feet pointing backwards. Whereas there are a few published records of waders flying with their legs folded forward (like a passerine), with legs and feet tucked in under the belly feathers, the causes and consequences of waders flying with folded legs are poorly understood. Through searching the literature, asking ornitho
Religion and Forced Displacement in Georgia
This policy report focuses on religion-state relations in Georgia and argues that competition between the Eastern Orthodox Church, the Armenian Apostolic Orthodox Church and the Muslim community have had an impact on state involvement with humanitarian programmes. The Georgian case stands out as the country experienced three waves of internal forced displacement. Each wavehas shown that religious
Transnational Solidarity, Migration, and the Refugee Crisis : (In)Formal Organising and Political Environments in Greece, Germany, and Denmark
Over the last decade, the unprecedented influx of refugees and migrants into the European Union has posed a significant challenge to Europe, with solidarity being contested at two fronts: first, the question of solidarity with refugees in terms of meeting adequate measures of protection and satisfying their elementary needs; and second, the question of solidarity within the European Union in terms
Early versus late initiation of GH replacement in adult-onset hypopituitarism
Introduction: Adult-onset growth hormone deficiency (AGHD) is usually the last deficiency to be substituted in hypopituitarism. In children with documented GH deficiency, treatment without delay is crucial for achieving optimal effects on growth and development. In adults, it is not known whether a delay in treatment initiation influences biochemical response and the favourable physiological effec
Eva Hansen-Melander and the circulation of knowledge within the cancer chromosome network
In 1953 Eva Hansen-Melander was appointed as a scientific assistant at the newly founded Cancer chromosome laboratory at Lund University, Sweden. The lab was set up by the cytologist Albert Levan, who started his career as a botanist studying Allium chromosomes but in the early 1950s changed his research focus to the studies of chromosomes in cancer cells. Levan developed close collaborations with
von Neumann's trace inequality for Hilbert–Schmidt operators
von Neumann's inequality in matrix theory refers to the fact that the Frobenius scalar product of two matrices is less than or equal to the scalar product of the respective singular values. Moreover, equality can only happen if the two matrices share a joint set of singular vectors, and this latter part is hard to find in the literature. We extend these facts to the separable Hilbert space setting

Dual Control of Linear Discrete-Time Systems with Time-Varying Parameters
We describe how the optimal dual controller for a discrete-time linear system can be found by approximately solving the corresponding Bellman equation using a neural network to represent the value function. We illustrate the method on an example with time-varying dynamics, where the new method is shown to give improved performance.
Comparison of Riemann and Lebesgue sampling for first order stochastic systems
The normal approach to digital control is to sample periodically in time. Using an analog of integration theory we can call this Riemann sampling. Lebesgue sampling or event based sampling, is an alternative to Riemann sampling. It means that signals are sampled only when measurements pass certain limits. In this paper it is shown that Lebesgue sampling gives better performance for some simple sys
