Reassembling and generating cultural networks
Mètode Science Studies Journal: Annual ReviewThis paper proposes a research agenda to study cultural networks that assumes their role both in making meaning and as adaptative tools for humans and their communities. First, the agenda grounds the study of cultural networks in Whitehead’s (1861–1947)

Lepton-Photon 01, 2002 The most recent theoretical and experimental results in the field of diffractive scattering are reviewed. A parallel between the two current theoretical approaches to diffraction, the DIS picture in the Breit frame and the dipole picture in the target frame, is given, accompanied by a description of the models to which the data are compared.

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Cell Automaton Simulation for Lock-in Phenomena [PDF]
, 2006 Recently, the lock-in phenomena are observed in economic scene. These phenomena can be explained not by traditional economic theories but by network externally and path dependency.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dissociation of phantom limb phenomena from stump tactile spatial acuity and sensory thresholds [PDF]
, 2005 Most amputees experience phantom limb sensations and/or phantom limb pain as well as residual limb (stump) pain that are resistant to treatment. Phantom phenomena are not homogeneous; each patient presents with a unique combination of spontaneous or ...

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

2012 IEEE International Conference on Oxide Materials for Electronic Engineering (OMEE), 2012 Interfaces are common microstructures and occur in natural and synthetic materials on the local to mesoscopic lenght scale, like ferroic twin walls or interfaces between amorphous and crystalline material. Individual interfaces can be thin walls extended over a few unit cells or even thicker walls up to several 10000 Å.

Anomalous Phenomena in Solid Dielectrics under High Electric Fields (Keynote)
, 2009 Solid dielectrics have been used extensively in electrical and electronic industries. In the power industry, ultra high voltage transmission and cost saving of power equipment often result in that the dielectrics are operating under high electric fields.

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
