The Adversity of Race and Place: Fourth Amendment Jurisprudence In \u3cem\u3eIllinois v. Wardlow\u3c/em\u3e, 528 S. Ct. 673 (2000)
This Case Note lays out Wardlow\u27s pertinent facts, describes the decisions of the Court and lower courts, and then analyzes the ramifications of the Court\u27s holding. In particular, this Case Note argues that the Court\u27s ruling recognizes substantially less Fourth Amendment protections for people of color and indigent citizens than for wealthy Caucasians. This perpetuates a cycle of humiliating experiences, as well as fear and mistrust of the police by many poor people of color
What Money Cannot Buy: A Legislative Response to C.RAC.K.
Children Requiring a Caring Kommunity (C.R.A.C.K.) is an organization that pays current or former drug addicts $200 to be sterilized. While generating great public controversy, C.R.A.C.K. is expanding rapidly throughout the country. Its clients are disproportionately poor women of color, who are coerced by the offer of money into permanently relinquishing their reproductive rights. This Note argues that C.R.A.C.K. is a program of eugenical sterilization that cannot be tolerated. Moreover, C.R.A.C.K. further violates settled national public policy by offensively commodifying the ill-commodifiable, by demeaning women, and by starting down a slippery slope with devastating consequences. This Note proposes legislation that would prohibit paid sterilizations
Justice and Law Journals
What is the role for a law journal in advancing justice? What is the role of a justice-minded practitioner in furthering legal scholarship? And what is the intersectionâpractically and normativelyâfor law journals, legal scholars, practitioners, and justice? This brief Article attempts to lay a foundation for answering these important, but oft-neglected, questions. In the following conversation, a frequent contributor to the Michigan Journal of Race & Law (MJRL) and a former Editor-in-Chief of the Journal posit some ideas on how legal scholarship engages with justice, and how race-conscious practitioners can interact with race-conscious legal scholars

Carbon, nitrogen and O(2) fluxes associated with the cyanobacterium Nodularia spumigena in the Baltic Sea
Photosynthesis, respiration, N2 fixation and ammonium release were studied directly in Nodularia spumigena during a bloom in the Baltic Sea using a combination of microsensors, stable isotope tracer experiments combined with nanoscale secondary ion mass spectrometry (nanoSIMS) and fluorometry. Cell-specific net C- and N2-fixation rates by N. spumigena were 81.6±6.7 and 11.4±0.9âfmol N per cell per h, respectively. During light, the net C:N fixation ratio was 8.0±0.8. During darkness, carbon fixation was not detectable, but N2 fixation was 5.4±0.4âfmol N per cell per h. Net photosynthesis varied between 0.34 and 250ânmol O2âhâ1 in colonies with diameters ranging between 0.13 and 5.0âmm, and it reached the theoretical upper limit set by diffusion of dissolved inorganic carbon to colonies (>1âmm). Dark respiration of the same colonies varied between 0.038 and 87ânmol O2âhâ1, and it reached the limit set by O2 diffusion from the surrounding water to colonies (>1âmm). N2 fixation associated with N. spumigena colonies (>1âmm) comprised on average 18% of the total N2 fixation in the bulk water. Net NH4+ release in colonies equaled 8â33% of the estimated gross N2 fixation during photosynthesis. NH4+ concentrations within light-exposed colonies, modeled from measured net NH4+ release rates, were 60-fold higher than that of the bulk. Hence, N. spumigena colonies comprise highly productive microenvironments and an attractive NH4+ microenvironment to be utilized by other (micro)organisms in the Baltic Sea where dissolved inorganic nitrogen is limiting growth
The Spectra of T Dwarfs I: Near-Infrared Data and Spectral Classification
We present near-infrared spectra for a sample of T dwarfs, including eleven
new discoveries made using the Two Micron All Sky Survey. These objects are
distinguished from warmer (L-type) brown dwarfs by the presence of methane
absorption bands in the 1--2.5 \micron spectral region. A first attempt at a
near-infrared classification scheme for T dwarfs is made, based on the
strengths of CH and HO bands and the shapes of the 1.25, 1.6, and 2.1
\micron flux peaks. Subtypes T1 V through T8 V are defined, and spectral
indices useful for classification are presented. The subclasses appear to
follow a decreasing T scale, based on the evolution of CH and
HO bands and the properties of L and T dwarfs with known distances.
However, we speculate that this scale is not linear with spectral type for cool
dwarfs, due to the settling of dust layers below the photosphere and subsequent
rapid evolution of spectral morphology around T 1300--1500 K.
Similarities in near-infrared colors and continuity of spectral features
suggest that the gap between the latest L dwarfs and earliest T dwarfs has been
nearly bridged. This argument is strengthened by the possible role of CH as
a minor absorber shaping the K-band spectra of the latest L dwarfs. Finally, we
discuss one peculiar T dwarf, 2MASS 0937+2931, which has very blue
near-infrared colors (J-K = 0.24) due to suppression of the 2.1
\micron peak. The feature is likely caused by enhanced collision-induced
H absorption in a high pressure or low metallicity photosphere.Comment: 74 pages including 26 figures, accepted by ApJ v563 December 2001;

OGFOD1 catalyzes prolyl hydroxylation of RPS23 and is involved in translation control and stress granule formation
2-Oxoglutarate (2OG) and Fe(II)-dependent oxygenase domain-containing protein 1 (OGFOD1) is predicted to be a conserved 2OG oxygenase, the catalytic domain of which is related to hypoxia-inducible factor prolyl hydroxylases. OGFOD1 homologs in yeast are implicated in diverse cellular functions ranging from oxygen-dependent regulation of sterol response genes (Ofd1, Schizosaccharomyces pombe) to translation termination/mRNA polyadenylation (Tpa1p, Saccharomyces cerevisiae). However, neither the biochemical activity of OGFOD1 nor the identity of its substrate has been defined. Here we show that OGFOD1 is a prolyl hydroxylase that catalyzes the posttranslational hydroxylation of a highly conserved residue (Pro-62) in the small ribosomal protein S23 (RPS23). Unusually OGFOD1 retained a high affinity for, and forms a stable complex with, the hydroxylated RPS23 substrate. Knockdown or inactivation of OGFOD1 caused a cell type-dependent induction of stress granules, translational arrest, and growth impairment in a manner complemented by wild-type but not inactive OGFOD1. The work identifies a human prolyl hydroxylase with a role in translational regulation
Adatoms in Graphene
We review the problem of adatoms in graphene under two complementary points
of view, scattering theory and strong correlations. We show that in both cases
impurity atoms on the graphene surface present effects that are absent in the
physics of impurities in ordinary metals. We discuss how to observe these
unusual effects with standard experimental probes such as scanning tunneling
microscopes, and spin susceptibility.Comment: For the Proceedings of the "Graphene Week 2008" at the ICTP in

Power counting and effective field theory for charmonium
We hypothesize that the correct power counting for charmonia is in the
parameter Lambda_QCD/m_c, but is not based purely on dimensional analysis (as
is HQET). This power counting leads to predictions which differ from those
resulting from the usual velocity power counting rules of NRQCD. In particular,
we show that while Lambda_QCD/m_c power counting preserves the empirically
verified predictions of spin symmetry in decays, it also leads to new
predictions which include: A hierarchy between spin singlet and triplet octet
matrix elements in the J/psi system. A quenching of the net polarization in
production at large transverse momentum. No end point enhancement in radiative
decays. We discuss explicit tests which can differentiate between the
traditional and new theories of NRQCD.Comment: 18 pages, 1 figure Replaced plot of the psi polarization parameter
