[Associated Press wire release report on United Airline's federal appeal for domestic partner ordinance exemption]

AP news wire release reporting on a case heard by the US federal appeals court regarding a San Francisco city ordinance mandating benefits for domestic partners of employees. Although United Airlines asked for an exemption, the court denied the request; in response, United Airlines announced it will offer domestic partner benefits to San Francisco employees to comply with the law, with benefits available to employees nationwide in May 2000.

Single-Iteration Learning Algorithm for Feed-Forward Neural Networks (open access)

Single-Iteration Learning Algorithm for Feed-Forward Neural Networks

A new methodology for neural learning is presented, whereby only a single iteration is required to train a feed-forward network with near-optimal results. To this aim, a virtual input layer is added to the multi-layer architecture. The virtual input layer is connected to the nominal input layer by a specird nonlinear transfer function, and to the fwst hidden layer by regular (linear) synapses. A sequence of alternating direction singular vrdue decompositions is then used to determine precisely the inter-layer synaptic weights. This algorithm exploits the known separability of the linear (inter-layer propagation) and nonlinear (neuron activation) aspects of information &ansfer within a neural network.

Preliminary Evaluation of Potential Occupational and Public Health Impacts of Sediment Decontamination Facilities for New York/New Jersey Harbor (open access)

Preliminary Evaluation of Potential Occupational and Public Health Impacts of Sediment Decontamination Facilities for New York/New Jersey Harbor

Sediment is accumulating in New York/New Jersey Harbor, and shipping channels are rapidly becoming too shallow for large ships. The Port Authority of New York/New Jersey has determined that dredging of the ship channels is essential to keep them navigable. About five million cubic yards of sediment must be removed per year to keep the channels open. Without dredging, the channels will soon become unusable, and the shoreside shipping and warehousing businesses that depend on them will fade away. The economic loss to the area would be devastating. But the deeper layers of sediment in the Harbor contain a broad range of pollutants that are hazardous to humans and the environment-a legacy of past discharges that are no longer permitted. These include heavy metals, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), chlorinated pesticides, and dioxins. As a result, there are several million cubic yards of sediments to be dredged per year that do not meet applicable criteria for ocean disposal and must be dealt with in some other way. A possible solution to the problem is to treat the dredged material to immobilize or destroy the contaminants and make the treated sediments suitable for disposal in the ocean or on …

Final Report: Catalytic Hydrocarbon Reactions over Supported Metal Oxides, August 1, 1995 - July 31, 1999 (open access)

Final Report: Catalytic Hydrocarbon Reactions over Supported Metal Oxides, August 1, 1995 - July 31, 1999

The research program focused on the catalysis of hydrodesulfurization (HDS) over molybdenum-based catalysts and how catalyst composition, redox ability, structure and neighboring sites control the catalytic properties of metal oxides. We sought to understand the catalytic features/sites that control hydrogenation, hydrogenolysis, and isomerization during HDS. Unprompted silica-supported molybdenum oxides and molybdenum sulfides were studied. Model catalyst systems were prepared from organometallic precursors or cluster compounds to generate supported structures that feature Mo(II) and Mo(IV) cations that are isolated or in ensembles and that have either Mo-O or Mo-S bonds. Conventional MOS{sub 2} catalysts, which contain both edge and rim sites, were be studied. Finally, single-layer MOS{sub 2} structures were also prepared from 2H-MoS{sub 2} powder so that the model systems could be compared against a disulfide catalyst that only involves rim sites. Catalytic reactions for thiophene and tetrahydrothione were studied over the various catalysts. Oxidation states were determined using X-ray photoelectron spectroscopy. X-ray crystallography was used to characterize and follow changes in the MOS{sub 2} structures. The program on metal oxides prepared supported oxides that have a specific structure and oxidation state to serve as model templates for the more complex commercial catalysts and then employed these structures in reaction …

Technology development for iron and cobalt Fischer-Tropsch catalysts (open access)

Technology development for iron and cobalt Fischer-Tropsch catalysts

The simple polymerization mechanism for the Fischer-Tropsch synthesis produces products which follows an Anderson-Schulz-Flory distribution. Thus, plotting the logarithm of the mole fraction versus carbon number will produce a straight line whose slope is related to alpha which is determined by the chain termination and propagation probabilities. In contrast, the products from laboratory and large commercial plants exhibit a two-alpha plot. Vapor-liquid calculations show that product accumulation cannot be responsible for the two-alpha plot when the alpha value is large enough to produce liquid products at the reaction temperature. Only in the case where alpha is small and all products are in the vapor phase, allowing evaporation of the startup solvent and a drying out of the reactor can a product accumulation produce a two-alpha plot. Results of filtration successes and failures from runs with the CSTR are described.

Ligand Intermediates in Metal-Catalyzed Reactions (open access)

Ligand Intermediates in Metal-Catalyzed Reactions

The longest-running goal of this project has been the synthesis, isolation, and physical chemical characterization of homogeneous transition metal complexes containing ligand types believed to be intermediates in the metal-catalyzed conversion of CO/H{sub 2}, CO{sub 2}, CH{sub 4}, and similar raw materials to organic fuels, feedstocks, etc. In the current project period, complexes that contain unusual new types of C{sub x}(carbide) and C{sub x}O{sub y} (carbon oxide) ligands have been emphasized. A new program in homogeneous fluorous phase catalysis has been launched as described in the final report.

Final Report: Travel Support Electromagnetic Induction Workshop, August 1, 1998 - July 31, 1999

During the tenure of this grant we focused our efforts on the treatment of (i) the behavior of the negative hydrogen ion, H{sup {minus}}, in a strong laser field (whose intensity extends well into the nonperturbative regime), and (ii) two-electron escape from a helium atom, He, by synchrotrons light. The calculations for H{sup {minus}} were done using perimetric coordinates u, v, and w, which are linear combinations of the three interparticle distances, together with the three Euler angles. The algebra involved in the implementation of the perimetric coordinate system can be quite formidable. However, we formulated [1] a general and tractable decomposition of the two-electron wavefunction which greatly facilitated the algebra. A complex Sturmian-type basis set, in these coordinates, was employed. One of the main advantages of the perimetric coordinates is that the matrices representing the system's Hamiltonian and its interaction with the radiation field are sparse, so that storage requirements and the number of operations are minimized. The correlation between the electrons is fully incorporated. Indeed, perimetric coordinates are ideally suited to situations where the correlation is strong; each of the planes u = 0, v = 0, ancl w = 0 has the special significance that the electrons …
