Radiation Pressure Feedback in Galaxies [PDF]
, 2011 We evaluate radiation pressure from starlight on dust as a feedback mechanism in star-forming galaxies by comparing the luminosity and flux of star-forming systems to the dust Eddington limit.

Search for anions in molecular sources: C4H- detection in L1527 [PDF]
, 2007 We present the results of a search for the negative ion C4H- in various dark clouds, low mass star-forming regions and photon-dominated regions (PDRs). We have also searched for C6H-, C2H- and CN- in some of the sources.

High-Energy Limit of Form Factors [PDF]
Physical Review, 1960 This theorem is proved: For finite charge renormalization constant Z3-1, the form factors describing any vertex with two particles on the mass shell must vanish at infinite momentum transfer. The relation of this result to the work of Lehmann, Symanzik, and Zimmermann is discussed.

A Search for H2O in the Strongly Lensed QSO MG 0751+2716 at z=3.2 [PDF]
, 2006 We present a search for 183 GHz H_2O(3_13-2_20) emission in the infrared-luminous quasar MG 0751+2716 with the NRAO Very Large Array (VLA). At z=3.200+/-0.001, this water emission feature is redshifted to 43.6 GHz.

Prediction and Verification of Forming Limit Diagrams Based on a Modified Shear Failure Criterion
Chinese Journal of Mechanical Engineering, 2023 The forming limit diagram plays an important role in predicting the forming limit of sheet metals. Previous studies have shown that, the method to construct the forming limit diagram based on instability theory of the original shear failure criterion is ...
