The Arctic has experienced large climate changes over recent decades, the largest for any region on Earth. To understand the underlying reasons for this climate sensitivity, reanalysis is an invaluable tool. The Arctic System Reanalysis (ASR) is a regional reanalysis, forced by ERA-Interim at the lateral boundaries and incorporating model physics adapted to(More)
The genetic mechanisms that regulate neurodegeneration are only poorly understood. We show that the loss of one allele of the p53 family member, p73, makes mice susceptible to neurodegeneration as a consequence of aging or Alzheimer's disease (AD). Behavioral analyses demonstrated that old, but not young, p73+/- mice displayed reduced motor and cognitive(More)
This paper presents the architecture as well as the circuit implementation of a ZigBee transceiver using 2.45 GHz band, which is compliant with the physical layer of IEEE 802.15.4 standard. A prototypical system and chip has been designed using 0.18-mum CMOS process with core area of 0.16 mm<sup>2</sup>. The simulation results shows the packet error rate is(More)
Sirs: In order to maintain homeostasis in living mammals, the sympathetic and parasympathetic nervous systems are usually antagonistic to each other. However, innervation of the salivary glands is one of the exceptions. Stimulation of the sympathetic nerve induces secretion of a proteinaceous fluid, while parasympathetic nerve stimulation causes copious(More)
Eight new -oxamido-bridged copper(II)–lanthanide(III)–copper(II) heterotrinuclear complexes formulated as Cu2(oxmap)2Ln(NO3)3 (Ln = La, Nd, Eu, Gd, Tb, Dy, Ho, Er), where oxmap stands for N,N -bis(2-methyl-2-aminopropyl)oxamido dianions, have been synthesized by the strategy of “complex as ligand”, and characterized by elemental analyses, molar conductivity(More)
The authors propose a communication scheme for collaboration groups to track objects in a sensor network. Inside a group, sensors are clustered dynamically to help group communication. Each cluster is a geographical hexagon area. Since tracking objects does not necessarily need all sensors to be running, the authors propose a local communication protocol to(More)
In this study, we sequenced a new type I ribosome-inactivating protein, trichoanguina, from the seeds of Trichosanthes anguina (snake gourd). Trichoanguina is a basic glycoprotein having an apparent molecular mass of 35.0 kD and possessing strong ribosome-inactivating activity. Trichoanguina was cleaved with cyanogen bromide and partially digested with(More)
