Designers of radio-frequency inductively-degenerated CMOS low-noise-amplifiers have usually not followed the guidelines for achieving minimum noise figure. Nonetheless, state-of-the- art implementations display noise figure values very close to the theoretical minimum. In this paper, we point out that this is due to the effect of the parasitic overlap capacitances in the MOS device. In particular,

Prepositions already formed a grammatical category in the Common German language. New Scandinavian pepositions were established during the preliterary and the early literary periods. In this paper it is demonstraed that most of them were grammaticalizations of prepositional phrases or adverbs linked to a noun by an established preposition. The genesis of these new prepositions is investigated sema

BACKGROUND Paroxysmal nocturnal haemoglobinuria (PNH) is a rare haematological disease characterised by chronic haemolysis, pancytopenia and venous thrombosis. The condition is attributable to a lack of control of complement attack on erythrocytes, thrombocytes and leukocytes, and can be diagnosed by means of flow cytometry. In this quality assurance study, we have reviewed information from the me

Climate warming is more pronounced in the Arctic than in other parts of the world. This warming affects the terrestrial cryosphere including permafrost with consequences ranging from societal impacts to changes in hydrology and feedbacks in the climate system such as those imposed by changing greenhouse gas exchanges. Permafrost dynamics in a marginal zone for its very existence is in this context

BACKGROUND: Patients with elevated intracranial pressure risk compromising their cerebral blood flow, resulting in ischemia. Lowering of the raised intracranial pressure, is therefore, mandatory. Reduction of the cerebral blood volume (CBV) might be target. In finding ways to do so, one has to be able to measure CBV. Measurement of CBV is, however, difficult. Radio(99mTc-)labeled erythrocytes (99m

Idiopathic pulmonary fibrosis is characterized by the accumulation of fibroblasts/myofibroblasts and aberrant remodeling of the lung parenchyma. However, the sources of fibroblasts in IPF lungs are unclear. Fibrocytes are circulating progenitors of fibroblasts implicated in wound healing and fibrosis. In this study we evaluated evidence for the presence of fibrocytes in the lung of patients with i

Obesity is a major global public health problem, and understanding its pathogenesis is critical for identifying a cure. In this study, a gene knockout strategy was used in post-neonatal mice to delete synoviolin (Syvn)1/Hrd1/Der3, an ER-resident E3 ubiquitin ligase with known roles in homeostasis maintenance. Syvn1 deficiency resulted in weight loss and lower accumulation of white adipose tissue i

This paper examines tongue body movements between two vowels with particular emphasis on the shape of the movement paths. Earlier work on tongue movements in speech has mostly focused on movements for consonants. The movements analyzed are from the first to the second vowel in a sequence of vowel-bilabial consonant-vowel. Native speakers of Japanese and Italian served as subjects. The linguistic m

This dissertation provides new insights on creativity and the lives of creative people, by availing of unique data-sets covering the lives, works and emotional states of famous music composers. The underlying research documents the long-run persistence of a society’s preference towards cultural goods and shows that the geography of composer births displays remarkable continuity over a period of se

Embryonic stem cells (ESCs) provide hope as a potential regenerative therapy for neurological conditions such as Parkinson's disease and spinal cord injury. Currently, ESC-based nervous system repair faces several problems. One major hurdle is related to problems in generating large and defined populations of the desired types of neurons from human ESCs (hESCs). Moreover, survival of grafted hESC-

BACKGROUND: Constitutive promoters that ensure sustained and high level gene expression are basic research tools that have a wide range of applications, including studies of human embryology and drug discovery in human embryonic stem cells (hESCs). Numerous cellular/viral promoters that ensure sustained gene expression in various cell types have been identified but systematic comparison of their a
