Immigrants and the Receipt of Unemployment Insurance Benefits
Using data from the Current Population Survey's Displaced Workers Supplements, this paper explores whether immigrants are more or less likely to file claims for unemployment insurance (UI) benefits than natives. We find that among those eligible for UI benefits, recent immigrants are less likely to file a UI claim than natives. There is also evidence that the impact of unions on UI take-up is larger for immigrants than natives, especially non-recent immigrants.
Unemployment Insurance, Unemployment Durations and Re-employment Wages
We develop an empirical model to estimate the impact of UI on unemployment duration and reemployment wages. The model estimates the UI receipt, unemployment duration and re-employment wage equations simultaneously and incorporates unobserved heterogeneity variables in each equation and allows them to be correlated. The NLSY79 data is used to estimate the model. Some results are found support of the positive effect of UI on re-employment wages.

Lowest common ancestor interconnection networks
Lowest Common Ancestor (LCA) networks are built using switches capable of connecting u + d inputs/outputs in a permutation pattern. For n source nodes and I stages of switches, n/d switches are used in stage l - n/d - u/d in stage l - 2, and in general , n-u^l-i-l/d^l-i switches in stage i. The resulting hierarchical structure possesses interesting connectivity and permutational properties. A full characterization of LCA networks is presented together with a permutation routing algorithm for a family of LCA networks. The algorithm uses the network itself to collect and disseminate information about the permutation. A schedule of O(dp log_d/u n) passes is obtained with a switch set-up cost factor of O(log_d/u n) (p is the minimum number of passes that an algorithm with global knowledge schedules)

Removal of an Impaled Intraocular Hair Comb Following Self-inflicted Trauma
Ocular trauma is one of the most common and vision-threatening ophthalmic presentations with a wide spectrum of complications, such as bleeding, infection, vision loss, and enucleation. A 64-year-old-male presented to the emergency department (ED) with a self-inflicted orbital penetrating injury with a hair comb. Computed tomography showed the comb traversed the medial orbit inferior to the medial rectus but did not damage the optic nerve; there were no globe or orbital wall fractures. His ocular exam was significant for a right eye afferent pupillary defect and decreased visual acuity 20/800, consistent with optic neuropathy. Primary concerns were stabilizing and removing the foreign body without causing further damage in the setting of an uncooperative patient. The comb was removed with the aid of local and systemic analgesia using gentle traction and normal saline irrigation. The patient was admitted for systemic and topical antibiotics and showed improvement in visual acuity and resolution of his optic neuropathy. This case illustrates the importance of rapid ED assessment and management of complex penetrating ocular trauma. Examination should specifically look for signs of globe rupture and optic nerve injury. Expedited foreign body removal should be managed together with an ophthalmologist with procedural sedation and broad-spectrum antibiotics to avoid further visual and infectious complications
Experimental Investigation of Polymer Solution Injection on External Boundary Layers
This paper describes an experimental study of the effects of injecting dilute aqueous polymer solutions into a turbulent boundary layer formed on a flat plate immersed in flowing water.
Hot-film anemometer techniques were employed in the measurement of the velocity profiles, turbulence intensities, and lateral correlation coefficients at a number of locations along the plate. Boundary layer growth parameters and the variation of the local skin friction coefficient were computed from the velocity profile data. The effects of polymer concentration and injection velocity on the local drag reduction are also presented.
It was found that momentum diffusivity was smaller than for pure water, and that the presence of the polymer molecules appeared to promote a more uniform distribution of the size of the turbulent eddies. Also, that the injection rate of a polymer solution can have a pronounced affect on the drag reduction
Antiferromagnetic critical pressure in URu2Si2 under hydrostatic conditions
The onset of antiferromagnetic order in URu2Si2 has been studied via neutron
diffraction in a helium pressure medium, which most closely approximates
hydrostatic conditions. The antiferromagnetic critical pressure is 0.80 GPa,
considerably higher than values previously reported. Complementary electrical
resistivity measurements imply that the hidden order-antiferromagnetic
bicritical point far exceeds 1.02 GPa. Moreover, the redefined
pressure-temperature phase diagram suggests that the superconducting and
antiferromagnetic phase boundaries actually meet at a common critical pressure
at zero temperature.Comment: 5 pgs, 4 figs; AFM ordered moment revised to 0.5 muB, added and
