Massive Satellites of Close-In Gas Giant Exoplanets (2009)

Cassidy, Timothy A., Mendez, Rolando, Arras, Phil, Johnson, Robert E., Skrutskie, Michael F.

We study the orbits, tidal heating and mass loss from satellites around close-in gas giant exoplanets. The focus is on large satellites which are potentially observable by their transit signature. We...

No sodium in the vapour plumes of Enceladus (2009)

Schneider, Nicholas M., Burger, Matthew H., Schaller, Emily L., Brown, Michael E., Johnson, Robert E., Kargel, Jeffrey S., ...

The discovery of water vapour and ice particles erupting from Saturn's moon Enceladus fuelled speculation that an internal ocean was the source. Alternatively, the source might be ice warmed, melted...

Requirement of yeast Rad1-Rad10 nuclease for the removal of 3'-blocked termini from DNA strand breaks induced by reactive oxygen species (2004)

Guzder, Sami N., Torres-Ramos, Carlos, Johnson, Robert E., Haracska, Lajos, Prakash, Louise, Prakash, Satya

The Rad1–Rad10 nuclease of yeast and its human counterpart ERCC1–XPF are indispensable for nucleotide excision repair, where they act by cleaving the damaged DNA strand on the 5′-side of the...

Discovery of soft X-ray emission from Io, Europa, and the Io Plasma Torus (2002)

Elsner, Ronald F., Gladstone, G. Randall, Waite, J. Hunter, Crary, Frank J., Howell, Robert R., Johnson, Robert E., ...

We report the discovery of soft (0.25-2 keV) X-ray emission from the Galilean satellites Io and Europa, probably Ganymede, and from the Io Plasma Torus (IPT). Bombardment by energetic (greater than...

Incidence of Herpes Simplex Virus Type 2 Infection in the United States (2001)

Armstrong, Gregory L., Schillinger, Julie, Markowitz, Lauri, Nahmias, Andre J., Johnson, Robert E., McQuillan, Geraldine M., ...

Between the time that two large, national surveys were conducted, the Second National Health and Nutrition Examination Survey (1976–1980) and the Third National Health and Nutrition Examination...

ACQUIRED IMMUNODEFICIENCY SYNDROME AMONG PATIENTS ATTENDING HEMOPHILIA TREATMENT CENTERS AND MORTALITY EXPERIENCE OF HEMOPHILIACS IN THE UNITED STATES (1985)

JOHNSON, ROBERT E., LAWRENCE, DALE N., EVATT, BRUCE L., BREGMAN, DENNIS J., ZYLA, LAWRENCE D., CURRAN, JAMES W., ...

The acquired immunodeficiency syndrome (AIDS) was first recognized among hemophiliacs in 1982. The authors have conducted investigations to determine the onset and incidence of AIDS among...

NEAR-SURFACE FLOW IN GLACIERS OBEYING GLEN'S LAW (1984)

JOHNSON, ROBERT E., McMEEKING, ROBERT M.

In determining the gravity-driven flow of a glacier or ice sheet which obeys Glen's flow law, previous methods have predicted infinite longitudinal stress at the glacier's surface. This physically...

THE SENIC SAMPLING PROCESS: DESIGN FOR CHOOSING HOSPITALS AND PATIENTS AND RESULTS OF SAMPLE SELECTION (1980)

QUADE, DANA, CULVER, DAVID H., HALEY, ROBERT W., WHALEY, FREDRICK S., KALSBEEK, WILLIAM D., HARDISON, C. DAVID, ...

Regulation of polymerase exchange between Polη and Polδ by monoubiquitination of PCNA and the movement of DNA polymerase holoenzyme

Zhuang, Zhihao, Johnson, Robert E., Haracska, Lajos, Prakash, Louise, Prakash, Satya, Benkovic, Stephen J.

To ensure efficient and timely replication of genomic DNA, organisms in all three kingdoms of life possess specialized translesion DNA synthesis (TLS) polymerases (Pols) that tolerate various types...

A Data Base System to Analyze the Epidemiology of Chlamydia Trachomatis Infections

Fichtner, Ronald R., Johnson, Robert E., Jenkins, William C., Harrison, H. Robert, Schrader, Mark V.

Infections due to Chlamydia trachomatis and their sequelae pose a major public health problem. An estimated three to four million Americans acquire chlamydial infections each year, and thus are...

Giving Everyone the Health of the Educated: An Examination of Whether Social Change Would Save More Lives Than Medical Advances

Woolf, Steven H., Johnson, Robert E., Phillips, Robert L., Philipsen, Maike

Objectives. Social determinants of health, such as inadequate education, contribute greatly to mortality rates. We examined whether correcting the social conditions that account for excess deaths...
