The United States traditionally has had close relations with Venezuela, a major supplier of foreign oil, but there has been friction in relations under the government of populist President Hugo Chávez. U.S. officials have expressed concerns about human rights, Venezuela's military arms purchases, its relations with Cuba and Iran, and its efforts to export its brand of populism to other Latin American countries. Declining cooperation on anti-drug and anti-terrorism efforts has also been a concern.

This report covers the issues Venezuela poses for Congress. It examines the Venezualian political situation, its economic conditions, the United States policy toward Venezuela, and the legislative initiatives of the 111th Congress regarding this foreign nation.

Since the September 2001 terrorist attacks on New York and Washington, U.S. attention to terrorism in Latin America has intensified, with an increase in bilateral and regional cooperation. This report discusses the issue in relation to the U.S. State Department's April 2009 Country Report on Terrorism; Colombian President Hugo Chávez's sympathies with terrorist groups and lack of cooperation on antiterrorism efforts; growing U.S. concern over activities of terrorist groups Hezbollah and Hamas in the tri-border area of Argentina, Brazil, and Paraguay; and various legislative initiatives related to Latin American terrorism issues being considered by the 112th Congress.

We present first-principles calculations of the structural and electronic properties of liquid nitrogen in the pressure-temperature range of 0-200 GPa and 2000-6000 K. The molecular-polymerization and molecular-atomic liquid phase boundaries have been mapped over this region. We find the polymeric liquid to be metallic, similar to what has been reported for the higher-temperature atomic fluid. An explanation of the electronic properties is given based on the structure and bonding character of the transformed liquids. We discuss the structural and bonding differences between the polymeric liquid and insulating solid cubic-gauche nitrogen to explain the differences in their electronic properties. Furthermore, we discuss the mechanism responsible for charge transport in polymeric nitrogen systems to explain the conductivity of the polymeric fluid and the semi-conducting nature of low-temperature amorphous nitrogen.

We present the cross section for production of a Z boson in association with four jets at the Large Hadron Collider, at next-to-leading order in the QCD coupling. When the Z decays to neutrinos, this process is a key irreducible background to many searches for new physics. Its computation has been made feasible through the development of the on-shell approach to perturbative quantum field theory. We present the total cross section for pp collisions at {radical}s = 7 TeV, after folding in the decay of the Z boson, or virtual photon, to a charged-lepton pair. We also provide distributions of the transverse momenta of the four jets, and we compare cross sections and distributions to the corresponding ones for the production of a W boson with accompanying jets.

The National Museum of the Pacific War presents an oral interview with Davis Mayes. Mayes joined the Army in the summer of 1936 and received basic training at Fort Sam Houston. While there, he taught himself to type. Upon completion of his three-year enlistment, he left to join the Navy, where his typing experience qualified him to become a radioman, copying down Japanese signals. He was on standby aboard the USS Solace (AH-5) during the attack on Pearl Harbor, bearing witness to the incredible destruction and its aftermath. His next assignment was as chief communicator for the USS Enoree (AO-69), coordinating 50 ships for the delivery of supplies to Europe. Next, he was assigned to a seagoing tug as chief radioman. As the only chief aboard, he instructed the crew in repairing everything from kitchen equipment to motors, salvaging parts from the mothball fleet. In the Korean War, he again went beyond his duties as a radioman and conducted repairs all over the USS Healey (DD-762). Mayes left the service in 1957 and went on to enjoy a 25-year career with the RCA Corporation. He was the only engineer there without a college education.

The prediction of backgrounds to new physics signals in topologies with large missing transverse energy and jets is important to new physics searches at the LHC. Following a CMS study, we investigate theoretical issues in using measurements of {gamma} + 2-jet production to predict the irreducible background to searches for missing energy plus two jets that originates from Z + 2-jet production where the Z boson decays to neutrinos. We compute ratios of {gamma} + 2-jet to Z + 2-jet production cross sections and kinematic distributions at next-to-leading order in {alpha}{sub s}, as well as using a parton shower matched to leading-order matrix elements. We find that the ratios obtained in the two approximations are quite similar, making {gamma} + 2-jet production a theoretically reliable estimator for the missing energy plus two jets background. We employ a Frixione-style photon isolation, but we also show that for isolated prompt photon production at high transverse momentum the difference between this criterion and the standard cone isolation used by CMS is small.

This report discusses the visa security and visa policy questions debated in Congress. The policy questions center on whether immigration law needs to be strengthened, whether funding should be increased, and which agency should take the lead.

This report provides an overview of the roles of the departments of state and homeland security on the Visa security policy.

The production of W bosons in association with jets is an important background to new physics at the LHC. Events in which the W carries large transverse momentum and decays leptonically lead to large missing energy and are of particular importance. We show that the left-handed nature of the W coupling, combined with valence quark domination at a pp machine, leads to a large left-handed polarization for both W{sup +} and W{sup -} bosons at large transverse momenta. The polarization fractions are very stable with respect to QCD corrections. The leptonic decay of the W{sup +-} bosons translates the common left-handed polarization into a strong asymmetry in transverse momentum distributions between positrons and electrons, and between neutrinos and anti-neutrinos (missing transverse energy). Such asymmetries may provide an effective experimental handle on separating W +jets from top quark production, which exhibits very little asymmetry due to C invariance, and from various types of new physics.
