    In this letter, a low-resistance ohmic contact on p-type GaN using an alloy of Ni/Pd/Au is reported. The Mg doped p-type GaN samples were grown by metalorganic chemical vapor deposition with a carrier concentration of 4.1×1017 cm−3. The as-grown Mg doped samples were deposited with Ni (20 nm)/Pd (20 nm)/Au (100 nm) and then annealed in air, nitrogen, and oxygen ambient conditions at different annealing temperatures ranging from 350 to 650 °C. Linear I–V ohmic characteristics were observed with specific resistance as low as 1.0×10−4 Ω cm2 for the samples annealed in oxygen atmosphere. Similar contact metal composition was also deposited on Be-implanted p-type GaN samples with a carrier density of 8.1×1019 cm−3. Without further annealing process, the samples show good ohmic contact with a lowest specific resistance of 4.5×10−6 Ω cm2. © 2000 American Institute of Physics.

    Background  Epidermal Langerhans cells (LCs) play an important role in cutaneous immunological reactions. Freshly obtained or intraepidermal LCs are incapable of activating autologous naive T cells. However, when they are cultured for 2–3 days, LCs are able to activate autologous T cells. It has been proposed that haptoglobin (Hp) is the inhibitor that prevents LC functional transformation in the skin. Abundant Hp has been found in the cytoplasm of epidermal LCs. However, the source of Hp in LCs has not been addressed.Objectives  To determine the expression of Hp in epidermal cells, and to provide evidence that there is a functional relationship between LCs and keratinocytes (KCs) through Hp.Methods  Normal human epidermal cells and HaCaT cells were used for detection of Hp mRNA by in situ hybridization and reverse transcription–polymerase chain reaction, and Hp protein by immunohistochemical staining, immunofluorescence counterstaining and Western blotting.Results  Hp mRNA was expressed in normal human KCs and HaCaT cells, but not in normal human epidermal LCs. Hp protein was detected by immunohistochemical staining and immunofluorescence counterstaining in CD1a+ epidermal dendritic cells (LCs), but not in KCs. Hp protein was weakly expressed by HaCaT cells.Conclusions  Hp mRNA is present in normal human KCs and HaCaT cells, suggesting that they have the potential to synthesize Hp protein. Normal human epidermal LCs are unable to synthesize Hp protein by themselves, although they have abundant Hp protein in their cytoplasm. It is likely that LCs acquire Hp through an exogenous pathway.

    Summary Several analogs of precocene have been synthesized and evaluated as potential inhibitors of juvenile hormone onLocusta migratoria. Only 5,7-dimethoxy-2,2-dimethylchromene was active; its ED50 and LD50 were measured and compared to those of precocene I and II.

    Notes:
    Summary Electrophysiological mapping techniques were used to determine the representation of the central field of vision in the superior colliculus of the albino rat. The retinotopic map for the contralateral eye is similar to that found in other mammals. There is an unexpected extensive binocular segment subserving the central 40° of the ipsilateral hemifield as well as the central 40° of the contralateral hemifield in the rostrolateral portion of the tectum.

    Notes:
    Summary Four hundred and fifteen cells were recorded in the binocular segment of the visual cortex in the albino rat. Cells encountered were mainly dominated by the contralateral eye. The percentage of binocularly-driven cells increased as the electrode was moved towards the border between areas 17 and 18a. Ninety percent of the cells studied in the region of the border could be driven by electrical stimulation applied at the corresponding site in the opposite hemisphere. Within area 17, however, there were only about 30% of such cells. Through the combined use of electrical stimulation and reversible cortical cooling, two types of contributions by callosal fibres were revealed. One is that the callosal fibres constitute the only inputs from the ipsilateral eye to a cell. The other is that the callosal input provides ipsilateral reinforcement to a binocular cell. These results are compatible with neuroanatomical findings and show that binocularity of visual cortical cells in this animal depends, to a great degree, on the function of callosal fibres.

    Two intense modes are observed in the low-frequency Raman spectra of as-grown and annealed linear aliphatic polyester single crystals. Our experimental data in conjunction with theoretical normal mode calculations of several model oligomers reveal the two bands observed to be vibrations of the longitudinal acoustic mode type. The unbalanced mass units associated with the ester groups couple the transverse and longitudinal motions, giving rise to the multiple modes.

    Notes:
    The longitudinal acoustic mode has been observed in a series of linear aliphatic polyesters. In some cases, the vibrational frequencies observed do not strictly obey the expected inverse chain-length relationship. Both the periodicity measured in small-angle x-ray diffraction and the chain length deduced from Raman spectroscopy are highly dependent on thermal history.
