    Titre: High sensitivity silicon single nanowire junctionless phototransistor
    Auteur: Das, Samaresh; Dhyani, Veerendra; Georgiev, Yordan M.; Williams, David A.
    Sujet: Nanoscale Science And Technology
    Description: A high-gain photodetector based on junctionless MOSEFT has been presented in this work. Tri-gate junctionless nanowire phototransistors were fabricated on (100) silicon-on-insulator wafers with a buried oxide of thickness 145 nm and top silicon layer of thickness 10 nm. The gate stack consisted of a 10 nm SiO 2 dielectric and a 50 nm poly-Si gate electrode. The channel length and doping concentration of junctionless n-MOSFETs was 1  μ m and 3 × 10 19  cm −3 , respectively. The dark current of this device measured at room temperature was less than 1 pA. The measured internal gain of the device was about 35 for 860 nm light illumination. The photocurrent was 300 times larger than the dark current for only 30 nW incident power on the nanowire at 300 mV drain bias.

    Sujet: ISM: molecules - galaxies: active - BL Lacertae objects: general - BL Lacertae objects: individual: 1ES 1959+650 - galaxies: distances and redshifts - galaxies: ISM
    Description: BL Lacertae (Lac) objects that are detected at very high energies (VHE) are of fundamental importance to study multiple astrophysical processes, including the physics of jets, the properties of the extragalactic background light and the strength of the intergalactic magnetic field. Unfortunately, since most blazars have featureless optical spectra that preclude a redshift determination, a substantial fraction of these VHE extragalactic sources cannot be used for cosmological studies. To assess whether molecular lines are a viable way to establish distances, we have undertaken a pilot programme at the Institut of Millimétrique (IRAM) 30 m telescope to search for CO lines in three BL Lac objects with known redshifts. We report a positive detection of  M⊙ towards 1ES 1959+650, but due to the poor quality of the baseline, this value is affected by a large systematic uncertainty. For the remaining two sources, W Comae and RGB J0710+591, we derive 3σ upper limits at, respectively, and 1.6 × 109  M⊙, assuming a line width of 150 km s−1 and a standard conversion factor α = 4  M⊙ (K km s−1 pc2)−1. If these low molecular gas masses are typical for blazars, blind redshift searches in molecular lines are currently unfeasible. However, deep observations are still a promising way to obtain precise redshifts for sources whose approximate distances are known via indirect methods. Our observations further reveal a deficiency of molecular gas in BL Lac objects compared to quasars, suggesting that the host galaxies of these two types of active galactic nuclei (AGN) are not drawn from the same parent population. Future observations are needed to assess whether this discrepancy is statistically significant, but our pilot programme shows how studies of the interstellar medium in AGN can provide key information to explore the connection between the active nuclei and the host galaxies

    Titre: The Chronic Difficulties in Isolating Chronically Infected Parvovirus B19 Patients
    Auteur: Walters, Elizabeth; Williams, David A; Williams, David
    Sujet: Public Health
    Description: With more sensitive molecular diagnostic testing, increased physician awareness and changing patient populations the proportion of patients testing positive for parvovirus B19 has tripled at our institution since 2007. Nosocomial transmission is infrequent, however patients with transient aplastic crisis...
