Low power multi-band CMOS receiver front-end

A Multi-band CMOS front-end was designed and fabricated in a 0.13μm CMOS process. The front-end employs a common-gate low noise amplifier (LNA) with capacitive cross coupling (CCC) technique and a double balanced mixer. The band selection is performed by switching capacitors in and out of the LNA load, changing the resonance frequencies ranging from 2.5GHz to 4.5GHz in 16 different frequency bands

On Self-Tuning Regulators

The problem of controlling a system with constant but unknown parameters is considered. The analysis is restricted to discrete time single-input single-output systems. An algorithm obtained by combining a least squares estimator with a minimum variance regulator computed from the estimated model is analysed. The main results are two theorems which characterize the closed loop system obtained under

Scale-invariant nonlinear optics in gases

Nonlinear optical methods have become ubiquitous in many scientific areas, from fundamental studies of timeresolved electron dynamics to microscopy and spectroscopy applications. They are, however, often limited to a certain range of parameters such as pulse energy and average power. Restrictions arise from, for example, the required field intensity as well as from parasitic nonlinear effects and

Ultra High-throughput Architectures for Hard-output MIMO Detectors in the Complex Domain

In this paper, a novel hard-output detection algorithm for the complex multiple-input multiple-output (MIMO) detectors is proposed, which results in a significant throughput enhancement, a near-ML performance, and an SNR-independent fixed-throughput. Moreover, a high-throughput VLSI implementation is proposed, which is based on a novel method of the node generation and sorting scheme. The proposed

Complementary III-V heterojunction lateral NW Tunnel FET technology on Si

We demonstrate for the first time a technology which allows the monolithic integration of both p-Type (InAs-Si) and n-Type (InAs-GaSb) heterojunction Tunnel FETs (TFET) laterally on a Si substrate. The lateral heterojunction nanowire (NW) structures are implemented using top-down CMOS-compatible processes combined with Template-Assisted Selective Epitaxy (TASE) [1] of the III-V materials. Sub-40nm

Production of b b ¯ at forward rapidity in p+p collisions at s =510 GeV PRODUCTION of b b ¯ at FORWARD RAPIDITY ... ACHARYA U et al..

The cross section of bottom quark-antiquark (bb¯) production in p+p collisions at s=510 GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider. The results are based on the yield of high mass, like-sign muon pairs measured within the PHENIX muon arm acceptance (1.21 GeV/c, and dimuon mass of 5-10 GeV/c2. The extrapolated total cross section at this energy for bb¯ productio

Guarding utopia : Law, vulnerability and frustration at the UN Human Rights Committee

In the 1940s activists lobbied for the creation of a binding international bill of rights backed up by an international human rights court as the backbone of the post‐World War II order. Together, so the activists believed, these would guarantee peace and harmony to all mankind. Seven decades later this vision has been transformed into a cluster of UN human rights treaties and expert committees kn

Ethical issues related to research on genome editing in human embryos

Although the potential advantages of clinical germline genome editing (GGE) over currently available methods are limited, the implementation of GGE in the clinic has been proposed and discussed. Ethical issues related to such an application have been extensively debated, meanwhile, seemingly less attention has been paid to ethical implications of studies which would have to be conducted in order t

Measuring Institutions : What We Do Not Know

The last two decades have seen a significant increase in the number and quality of cross-national measures of institutions, which are also covering longer and longer time spans. However, despite the considerable progress that has been made, important measurement issues linger. This chapter argues that the key future challenge for the measurement of institutions is how to square objective or direct

Engaging pre-service English teachers with language policy

Teachers have the potential to be active agents in language policy and planning (LPP) processes when designing lessons or managing linguistic resources in their classrooms. A key consideration, then, is to guide pre-service educators towards an understanding of LPP principles and how they can be applied in practice. The present study documents an interactive LPP roleplay project that was designed

Synthesis and subsequent purification of carbon nanotubes by arc discharge in NaCl solution

Carbon nanotubes (CNTs) are fascinating structures with a wide range of applications and several methods have been developed for their fabrication. The arc-discharge in liquid method is a new technique for synthesis of nanocarbon structures and is recognized as a low-cost method. In this work, this method was used for fabrication of carbon nanotubes, and subsequently a modified acid treatment meth

Management of paraesophageal hiatus hernia : recommendations following a European expert Delphi consensus

AIMS: There is considerable controversy regarding optimal management of patients with paraesophageal hiatus hernia (pHH). This survey aims at identifying recommended strategies for work-up, surgical therapy, and postoperative follow-up using Delphi methodology.METHODS: We conducted a 2-round, 33-question, web-based Delphi survey on perioperative management (preoperative work-up, surgical procedure

Senior arbetskraft : – en systematisk kunskapssammanställning med fokus på mental arbetsmiljö och arbetssocial miljö i Sverige

UppdragArbetet med kunskapssammanställningen definierades av Myndigheten förarbetsmiljökunskap till att omfatta den psykosociala arbetsmiljöns inverkanpå den seniora arbetskraften1 i en svensk kontext, det vill säga effekten påindividen utifrån den mentala arbetsmiljö och den arbetssociala miljö somhen befinner sig i. Dock samvarierar olika faktorer i individers arbetssitua-tion. För att fånga in This report from the Swedish Agency for Work Environment Knowledge isconcerned with the impact of the psychosocial work environment — that is,the mental work environment and social work environment — on the seniorworkforce (≥55 years of age) in a Swedish context. However, many differentfactors can affect an individual’s work situation. Therefore, the studies inclu-ded in this literature review hav

Abstract in French:Cet article contribue à la recherche sur la géopolitique urbaine par une théorisation « extrospective » du pouvoir local sur la scène internationale – c’est-à-dire une orientation du développement socio-économique qui encourage tant la concurrence que la coopération entre les entités métropolitaines au-delà des frontières de l’État-nation. Empiriquement, l’article se concentre sThis article contributes to research on urban geopolitics through an extrospective theorization of local territorial influence on the international stage. Empirically, the article focuses on a comparative study of extrospective development initiatives from Malaga (Spain) and Mazara del Vallo (Sicily) that have recently emerged in response to the effects of the Great Recession. We examine the symbo

A modeling framework for the dynamic management of free-floating bike-sharing systems

Given the growing importance of bike-sharing systems nowadays, in this paper we suggest an alternative approach to mitigate the most crucial problem related to them: the imbalance of bicycles between zones owing to one-way trips. In particular, we focus on the emerging free-floating systems, where bikes can be delivered or picked-up almost everywhere in the network and not just at dedicated dockin

The concept of hyperenculturation : An example from a Swedish research school

The aim of this paper is to discuss how research schools with a structured programme and targeted profile may make it difficult for doctoral students to expand the academic role. Our paper is based on material collected in a questionnaire given to doctoral students enrolled at a Swedish research school in architecture. In this questionnaire we found three areas – openness to other disciplines and

Communicating the environmental characteristics of products: the use of environmental product declarations in the building, energy and automotive industries

Environmental policy is shifting the focus from production processes to product-related issues. The provision and use of environmental information is generally considered an essential element in addressing the environmental impacts associated with the life cycle of products. Environmental product declarations (EPD) are one of the much promoted informative instruments. A wide range of self-declarat
