Analysis and design of a double-quadrature CMOS VCO for subharmonic mixing at Ka-band

In this paper, we analyze the potentials of a four-phase 14-GHz CMOS voltage-controlled oscillator, tailored to a sub-harmonic receiver, for signal processing at Ka-band. When mild phase accuracies between in-phase and quadrature down-converted signals are required, the four-phase oscillator displays roughly the same phase noise figure-of-merit as quadrature oscillator counterparts. However, the o

On reduced-complexity equalization based on Ungerboeck and Forney observation models

This correspondence investigates the asymptotic behavior of reduced-state ISI equalizers, based on the Ungerboeck and Forney observation models. It is shown that Ungerboeck-based equalizers can suffer from correct-path-loss (CPL) even in the noiseless regime. ISI conditions that lead to CPL are analytically derived and illustrated by examples.

How to make a workplace health promotion questionnaire process applicable, meaningful and sustainable.

How to make a workplace health promotion questionnaire process applicable, meaningful and sustainable Background In workplace health promotion, a questionnaire could be of great use. Unfortunately, fatigue regarding answering questionnaires has recently become greater than before. An action research approach could be a possible way of increasing employee participation. Aim This study reports an at

Fuktdimensionering av betongplatta

I ett examensarbete som nyligen avslutats på Byggnadsmaterial, Chalmers, har man tagit reda på vad aktörerna i byggbranschen vet om fuktdimensionering. I arbetet intervjuades ett flertal konsulter, entreprenörer och beställare om deras syn på fuktfrågor i byggandet.

Noninvasive Single-Exon Fetal RHD Determination in a Routine Screening Program in Early Pregnancy.

OBJECTIVE: To develop a simple and robust assay suitable for fetal RHD screening in first-trimester pregnancy and to estimate the sensitivity and specificity of the test after its implementation in an unselected pregnant population. METHODS: Pregnant women attending their first antenatal visit were included, and fetal RHD determination was performed for all women who typed RhD-negative by routine

Allogeneic Hematopoietic Stem Cell Transplantation in the Treatment of Human C1q Deficiency: The Karolinska Experience.

Human C1q deficiency is associated with systemic lupus erythematosus (SLE) and increased susceptibility to severe bacterial infections. These patients require extensive medical therapy and some develop treatment-resistant disease. Because C1q is produced by monocytes, it has been speculated that allogeneic hematopoietic stem cell transplantation (allo-HSCT) may cure this disorder.

Constructing a Distinct Other: Harry Potter and the Enchantment of the Future

In this article I argue that the Harry Potter series could function as a critique or commentary to the ordinary contemporary society. Rowling’s construction of the Wizard world bears resemblance to a distinct Other, which is frequently used by the tourist industry and various religious traditions. While the main purpose for the tourist industry to invoke a distinct Other lies in its promoting abil

Grasping Technology, Assessing Craft. Developing a Research Method for the Study of Craft-Tradition

This thesis is concerned with the subject of craft and technology and the intricate connection between man, his objects and society. When archaeologists study social and cultural structures and phenomena, it is understood that the objects have been created and crafted by people, but the weight of this fact is not always recognized. Acknowledging that we are always studying the material expression

Association of the Variants CASP8 D302H and CASP10 V410I with Breast and Ovarian Cancer Risk in BRCA1 and BRCA2 Mutation Carriers.

BACKGROUND: The genes caspase-8 (CASP8) and caspase-10 (CASP10) functionally cooperate and play a key role in the initiation of apoptosis. Suppression of apoptosis is one of the major mechanisms underlying the origin and progression of cancer. Previous case-control studies have indicated that the polymorphisms CASP8 D302H and CASP10 V410I are associated with a reduced risk of breast cancer in the

A novel assay to trace proliferation history in vivo reveals that enhanced divisional kinetics accompany loss of hematopoietic stem cell self-renewal.

BACKGROUND: The maintenance of lifelong blood cell production ultimately rests on rare hematopoietic stem cells (HSCs) that reside in the bone marrow microenvironment. HSCs are traditionally viewed as mitotically quiescent relative to their committed progeny. However, traditional techniques for assessing proliferation activity in vivo, such as measurement of BrdU uptake, are incompatible with pres
