Integrated predictive modeling of JET H-mode plasma with type-I and type-III ELMs
Edge plasma parameters influence plasma performance in many different ways (profile stiffness is probably one of the best known examples). In the ELMy H-mode plasma, a thin region with improved transport chara...

The eternal molecule
Few molecules captivate like DNA. It enthrals scientists, inspires artists, and challenges society. It is, in every sense, a modern icon. A defining moment for DNA research was the discovery of its structure ha.....

Chaos in percepts?
Multistability in perceptual tasks has suggested that the mechanisms underlying our percepts might be modeled as nonlinear, deterministic systems that exhibit chaotic behavior. We present evidence supporting t...

A study of top quark production at HERA using parton shower simulation of DIS events
A study of the hadronic properties of top quark events at HERA is made in the hope that some characteristics of such events may emerge that distinguish them from light flavour QCD events. Electronproton collis...

Conversion of Solar Energy Using Fluorescent Collectors: Installation of a Test Collector to Deliver Several Watts Power
A 1 m2 fluorescent collector has been built which, with Si solar cells, js already capable of delivering 6 W at maximum insolation (1 kWm−2), and has the potential for output powers exceeding 20 W, when optimized...

Psychophysical Evidence for Spatial Channels
More than a decade of research spawned by the work of CAMPBELL and ROBSON [1] and GRAHAM and NACHMIAS [2] has led to a general consensus that the human visual system contains several different classes of spati...

Structure of thymidylyl-3′, 5′-deoxyadenosine
THE triethylammonium salt of the dinucleoside phosphate, thymidylyl-3′, 5′-deoxyadenosine (TpdA) forms helical structures when aqueous solutions are allowed to evaporate1. There are some similarities between the ...

Lead toxicity of Bobwhite quail
Five experiments were conducted involving both juvenile and adult Bobwhite quail (Colinus virginianus) to study the toxicity of lead acetate, lead shot, powdered lead and antimony. Performance of juvenile birds r...

Double helix formed by the dinucleoside phosphate thymidylyl-3′,5′ -deoxyadenosine
IN our conformational studies of nucleic acid components we have obtained X-ray diffraction photographs from specimens of the dinucleoside phosphate thymidylyl-3′,5′-deoxyadenosine (TpdA) which are similar to ...

Molecular conformation of deoxyguanosine 5′-phosphate
THE allowed conformations of nucleic acids depend on the flexibility of the structure of the nucleotides from which they are constructed. Many X-ray crystallographic studies of the degree of flexibility of the...

A mathematical theory of the functional dynamics of cortical and thalamic nervous tissue
It is proposed that distinct anatomical regions of cerebral cortex and of thalamic nuclei are functionally two-dimensional. On this view, the third (radial) dimension of cortical and thalamic structures is ass...

Biological Sciences: Changes in Nucleoside Conformation
Arnott and Hukins1, and Sundaralingam2, have recently compared the conformational parameters of nucleosides and nucleotides with those found in polynucleotide structures. Two of the parameters they discuss are th...

Molecular Conformation of Thymidine and a Comparison with some Electron Spin Resonance Results
THE determination of the structure of thymidine (C10 N2 O5 H14, Fig. 1) was undertaken as part of a series of structure determinations of nucleic acid components. Thymidine is the only nucleoside which has bee...

Structures of 5-Bromodeoxyuridine and 5-Bromouridine
HALOGENATED deoxyuridines can be incorporated into DNA in place of the normal thymidine component, and this affects the physical properties of the DNA and has important biological consequences. For example, it...

Fibres of Guanine Nucleosides and Nucleotides
IT has been shown by Gellert, Lipsett and Davies1 that guanylic acid will form a gel under certain pH conditions and they were able to draw fibres from gels of the disodium salt of 3′-guanylic acid and of the fre...

Structure of Guanine Hydrochloride Dihydrate
IN the structure determination of deoxyribonucleic acid (DNA), the method of molecular model building must be combined with that of X-ray diffraction because of the overlap and weakness of the small spacing sp...
