A Gate Forever Closed? Retiring Immigration Law’s Post-departure Bar

Immigration law’s “post-departure bar” destroys the jurisdiction of either an immigration judge or the Board of Immigration Appeals to hear a motion to reopen or reconsider filed by an alien who is no longer physically within the country. This Note examines the current conflict between the federal circuits regarding the post-departure bar and why the circuits that have decided to strike down the bar in the cases before them have ruled in line with certain trends present in recent Supreme Court immigration cases. Conflict between the circuits has arisen because the governing statute, the Illegal Immigration Reform and Immigrant Responsibility Act of 1996, was enacted without reference to the bar, which had been in place before the Act’s passage. In that statutory silence, the Attorney General promulgated regulations intended to reestablish the bar. In recent years, circuits have taken various positions on the bar’s validity. Many have struck the bar down on the basis of either Chevron deference or the grounds outlined in Union Pacific Railroad Co. v. Brotherhood of Locomotive Engineers, which bars an agency from limiting its jurisdiction in certain situations. Still, other circuits have upheld the bar by using Chevron to conclude that deference to the agency is proper. This Note suggests that the circuits that have struck down the bar are in line with prevailing trends in recent immigration cases decided by the Supreme Court. Further, this Note argues that it does not matter whether a circuit court relies upon Chevron or Union Pacific to strike down the bar, as the use of either precedent to attack the bar serves these trends, and is consistent with the overall direction of American immigration law

Fixture aids soldering of electronic components on circuit board

Spring clamp fixture holds small electronic components in a desired position while they are being soldered on a circuit board. The spring clamp is clipped on the edge of the circuit board and an adjustable spring-steel boom holds components against the board. The felt pad at the end of the boom is replaced with different attachments for other holding tasks

Similarities between organic and cuprate superconductors

This ``Perspective'' briefly reviews recent work showing that a class of organic superconductors have important similarities to the cuprate superconductors: (i) There is competition betweeen superconductivity and antiferromagnetism. (ii) Uncoventional metallic behavior is observed near the metal-insulator transition. A more detailed review and discussion of the appropriate strongly correlated electron model can be found in cond-mat/9802198.Comment: 2 pages, RevTeX + epsf, 1 figure

An x ray scatter approach for non-destructive chemical analysis of low atomic numbered elements

A non-destructive x-ray scatter (XRS) approach has been developed, along with a rapid atomic scatter algorithm for the detection and analysis of low atomic-numbered elements in solids, powders, and liquids. The present method of energy dispersive x-ray fluorescence spectroscopy (EDXRF) makes the analysis of light elements (i.e., less than sodium; less than 11) extremely difficult. Detection and measurement become progressively worse as atomic numbers become smaller, due to a competing process called 'Auger Emission', which reduces fluorescent intensity, coupled with the high mass absorption coefficients exhibited by low energy x-rays, the detection and determination of low atomic-numbered elements by x-ray spectrometry is limited. However, an indirect approach based on the intensity ratio of Compton and Rayleigh scattered has been used to define light element components in alloys, plastics and other materials. This XRS technique provides qualitative and quantitative information about the overall constituents of a variety of samples

A two-state model of twisted intramolecular chargetransfer in monomethine dyes

A two-state model Hamiltonian is proposed to model the coupling of twisting displacements to charge-transfer behavior in the ground and excited states of a general monomethine dye molecule. This coupling may be relevant to the molecular mechanism of environment-dependent fluorescence yield enhancement. The model is parameterized against quantum chemical calculations on different protonation states of the green fluorescent protein chromophore (GFP), which are chosen to sample different regimes of detuning from the cyanine (resonant) limit. The model provides a simple yet realistic description of the charge transfer character along two possible excited state twisting channels associated with the methine bridge. It describes qualitatively different behavior in three regions that can be classified by their relationship to the resonant (cyanine) limit. The regimes differ by the presence or absence of twist-dependent polarization reversal and the occurrence of conical intersections. We find that selective biasing of one twisting channel over another by an applied diabatic biasing potential can only be achieved in a finite range of parameters near the cyanine limit.Comment: 45 pages, 9 Figures (incl. 2 chemical schemes).
