In New York Times Co. v. Sullivan, The Supreme Court Got It Right Then- and Now

On April 5, 1960, Ray Jenkins, a city editor for the Alabama Journal,the afternoon paper in Montgomery, was having lunch at his desk and skimming through the old papers that had piled up. They included a week-old copy of the New York Times. He spotted an item that had a local angle, and he wrote a thirteen-paragraph story for that day\u27s paper. Sixty prominent liberals, including [former First Lady] Eleanor Roosevelt, have signed a full page advertisement in the New York Times appealing for contributions to \u27The Committee to Defend Martin Luther King and the Struggle for Freedom in the South,\u27 it began. He reported the ad as saying King and the students were facing an unprecedented wave of terror in Alabama. He noted several minor factual errors. While the ad said, Negro student leaders from Alabama State College were expelled after they sang \u27My Country \u27Tis of Thee\u27 on the state Capitol steps, Jenkins said they were expelled for leading a sit-down strike at the Courthouse Grill. \u27 The article caught the attention of Grover Hall, the editor of the Montgomery Advertiser. Lies, lies, lies-and possibly willful ones, he wrote in an editorial that appeared two days later. The Republic paid a dear price once for the hysteria and mendacity of abolitionist agitators. The author of this ad is a lineal descendant of those abolitionists and the breed runs true. Hall gave a copy of the New York Times ad to an attorney for the city and urged him to show it to City Hall because it libeled every one of them. How is that for a strange beginning to what became the most important freedom-of-the-press case in the Supreme Court\u27s history? It took a local newspaper editor to report on a paid ad that had appeared in an out-of-town paper, that in turned riled up a local editor who urged city officials to take umbrage and to sue. Thanks to these local newspapermen, Montgomery\u27s Commissioner of Public Safety L.B. Sullivan learned he had been libeled in the New York Times by an ad which, as has often been noted, did not mention him. Notice too the mindset reflected in Hall\u27s editorial. Nearly a century after the Civil War had ended slavery, Hall referred to the abolitionists as agitators given to hysteria and mendacity. \u27 As the Alabama editor saw it, the Civil Rights Movement led by Dr. King was engaged in a campaign of slander against the South, one that could provoke violence

Determination of Turboprop Reduction Gearbox System Fatigue Life and Reliability

Two computational models to determine the fatigue life and reliability of a commercial turboprop gearbox are compared with each other and with field data. These models are (1) Monte Carlo simulation of randomly selected lives of individual bearings and gears comprising the system and (2) two-parameter Weibull distribution function for bearings and gears comprising the system using strict-series system reliability to combine the calculated individual component lives in the gearbox. The Monte Carlo simulation included the virtual testing of 744,450 gearboxes. Two sets of field data were obtained from 64 gearboxes that were first-run to removal for cause, were refurbished and placed back in service, and then were second-run until removal for cause. A series of equations were empirically developed from the Monte Carlo simulation to determine the statistical variation in predicted life and Weibull slope as a function of the number of gearboxes failed. The resultant L(sub 10) life from the field data was 5,627 hr. From strict-series system reliability, the predicted L(sub 10) life was 774 hr. From the Monte Carlo simulation, the median value for the L(sub 10) gearbox lives equaled 757 hr. Half of the gearbox L(sub 10) lives will be less than this value and the other half more. The resultant L(sub 10) life of the second-run (refurbished) gearboxes was 1,334 hr. The apparent load-life exponent p for the roller bearings is 5.2. Were the bearing lives to be recalculated with a load-life exponent p equal to 5.2, the predicted L(sub 10) life of the gearbox would be equal to the actual life obtained in the field. The component failure distribution of the gearbox from the Monte Carlo simulation was nearly identical to that using the strict-series system reliability analysis, proving the compatibility of these methods

Genetic Defects in the Growth Hormone–IGF-I Axis Causing Growth Hormone Insensitivity and Impaired Linear Growth

Human genetic defects in the growth hormone (GH)–IGF-I axis affecting the IGF system present with growth failure as their principal clinical feature. This is usually associated with GH insensitivity (GHI) presenting in childhood as severe or mild short stature. Dysmorphic features and metabolic abnormalities may also be present. The field of GHI due to mutations affecting GH action has evolved rapidly since the first description of the extreme phenotype related to homozygous GH receptor (GHR) mutations in 1966. A continuum of genetic, phenotypic, and biochemical abnormalities can be defined associated with clinically relevant defects in linear growth. The mechanisms of the GH–IGF-I axis in the regulation of normal human growth is discussed followed by descriptions of mutations in GHR, STAT5B, IGF-I, IGFALS, IGF1R, and GH1 defects causing bio-inactive GH or anti-GH antibodies. These GH–IGF-I axis defects are associated with a range of clinical, and hormonal characteristics. An up-dated approach to the clinical assessment of the patient with GHI focusing on investigation of the GH–IGF-I axis and relevant molecular studies contributing to the identification of causative genetic defects is also discussed

Renormalons in Effective Field Theories

We investigate the high-order behavior of perturbative matching conditions in effective field theories. These series are typically badly divergent, and are not Borel summable due to infrared and ultraviolet renormalons which introduce ambiguities in defining the sum of the series. We argue that, when treated consistently, there is no physical significance to these ambiguities. Although nonperturbative matrix elements and matching conditions are in general ambiguous, the ambiguity in any physical observable is always higher order in $1/M$ than the theory has been defined. We discuss the implications for the recently noticed infrared renormalon in the pole mass of a heavy quark. We show that a ratio of form factors in exclusive $\Lambda_b$ decays (which is related to the pole mass) is free from renormalon ambiguities regardless of the mass used as the expansion parameter of HQET. The renormalon ambiguities also cancel in inclusive heavy hadron decays. Finally, we demonstrate the cancellation of renormalons in a four-Fermi effective theory obtained by integrating out a heavy colored scalar.Comment: Minor changes mad

Submillimeter-wave antennas on thin membranes

Submillimeter-wave antennas with bismuth microbolometer detectors have been fabricated on 1-μm thick silicon-oxynitride membranes. This approach results in better patterns than previous lens-coupled integrated circuit antennas, and eliminates the dielectric loss associated with the substrate lens. Measurements on a wideband log-periodic antenna at 700 GHz, 380 GHz and 167 GHz, and on a 700 GHz log-periodic imaging array, show no sidelobee and a 3-dB beamwidth between 40° and 50°. Also, the effective area can be increased by 5 dB by the use of a back-shorting mirror. Possible application areas are superconducting tunnel junction receivers for radio astronomy and imaging arrays for plasma diagnostics
