A 2GHz, 17% tuning range quadrature CMOS VCO with high figure-of-merit and 0.6° phase error

This paper presents a quadrature VCO implemented in a standard 0.35µm CMOS process. The VCO draws 16mA from a 1.3V power supply, can be tuned between 1.91 GHz and 2.27GHz, and displays a phase noise of -140dBc/Hz or less at 3MHz offset frequency from the carrier, for a minimum phase-noise figure-of-merit of 184 dB. The maximum departure from quadrature between the VCO phases is 0.6°.

Towards a decarbonized green state? The politics of low-carbon governance in Sweden

In this chapter we explore how a decarbonized green state might develop. Climate governance provides venues towards decarbonization and for greening the state by steering and enabling transformative social change. We study low-carbon transitions in Sweden in a set of policy sectors for their potential to reduce carbon emissions, spur innovation and enter policy paths towards decarbonization. Swede

Familial factors in anorexia nervosa: a community-based study

A group of 51 cases with teenage anorexia nervosa (AN; including a total population of cases from one birth cohort) were compared with a sex-, age-, and school-matched group of 51 cases on familial factors. The subjects were examined at age 16 and 21 years. In the first study, mothers of both groups were interviewed regarding physical and psychiatric disorders among first-degree relatives. In the

Starka belägg för att proffsboxning leder till kroniska hjärnskador. Ju fler slag mot huvudet under en boxares karriär, desto större är risken

The clinical symptomatology and pathogenic mechanisms of chronic traumatic brain injury associated with boxing (CTBI-B) is reviewed. This syndrome is also known as punch drunk syndrome or dementia pugilistica. Since even milder forms of CTBI-B are rare among amateur boxers, we make a distinction between amateur and professional boxing throughout the review. Focus is also set on the interesting sim

Temperature and soil C decomposition – synthesis of current knowledge and a way forward

The response of soil organic matter (OM) decomposition to increasing temperature is a critical aspect of ecosystem responses to global change. The impacts of climate warming on decomposition dynamics have not been resolved due to apparently contradictory results from field and lab experiments, most of which has focused on labile carbon with short turnover times. But the majority of total soil carb

The Mechanics of Constitutive Modeling

Constitutive modeling is the most intensive research field within solid mechanics. This work offers a comprehensive, parallel treatment of constitutive models and appropriate numerical solution strategies, at a conceptual level and with discussion of specific models for illustration. The exposion of each topic is self-contained and complete with extensive references for further reading. The gener

Nature and the Environment as Trans-Boundary Business Strategies

From a paradigmatic understanding of tourism, the thing about tourism experiences is that they differ from everyday life. You experience different places, see different people, get to know different ways of doing things, and so on. To do tourism, then, is to experience a series of changes from the ordinary. Several things change in the course of the making and consumption of a tourism product. For

Closed form solution for threshold velocity for initiation of sediment motion under waves

The present paper presents a rational expression for the initiation of motion for non-cohesive sediment under rough turbulent wave conditions. Previously proposed relationships for the initiation of motion are examined as well as laboratory measurements corresponding to fully rough turbulent boundary layers (which is normally the case under prototype conditions). By combining the modified Shields

Smart Skin for tactile prosthetics

This paper provides an overview of a concept for a Smart Skin, for enabling tactile prosthetics that provide for a natural sensation of touch. The solution embeds miniature, ultra-low power, wireless sensors into the silicone coating of the prosthetic. The solution offers advantages in terms of scalability, ability to place the sensors almost anywhere, fault tolerance and potential ease of manufac

Everyday Forms of Resistance to the Law: An Ethnographic Study of Street Vendors in Bogotá

Selling goods or providing services in public spaces is one of the most accessible occupations for many individuals living in poverty in today’s world. However, most street vendors conduct their businesses by disobeying laws that prohibit this kind of work. Drawing on field data on street vendors in the city of Bogotá, Colombia, this article ethnographically explores vendors’ ideas, perceptions, a

Uncertainty-Based Scheduling: Energy-Efficient Ordering for Tasks with Variable Execution Time

Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v
