Jet Correlations of Identified Particles in PHENIX
Azimuthal two particle correlations at intermediate with one of the
particles identified have been measured at PHENIX. Trigger () baryons and mesons show little significant difference in the number of
associated particles () independent of centrality. For
inclusive hadron triggers with , associated
fragmentation particles with show a higher baryon to
meson ratio on the away side.Comment: talk given at Quark Matter 2004, 4 pages 4 figur

Recombination Models
We review the current status of recombination and coalescence models that
have been successfully applied to describe hadronization in heavy ion
collisions at RHIC energies. Basic concepts as well as actual implementations
of the idea are discussed. We try to evaluate where we stand in our
understanding at the moment and what remains to be done in the future.Comment: Plenary Talk at Quark Matter 2004, submitted to J. Phys. G, 8 pages,

The Return To Tax Simplification: an Econometric Analysis
This article provides estimates of the probable saving in the resource cost of complying with the tax law that would result from simplifying the individual Abstract income tax law. These estimates are based on an econometric analysis of the tax-filing behavior in 1982 of a sample of Minnesota taxpayers. A simple model of tax-compliance behavior based on utility maximization is first presented in order to suggest the important determinants of compliance behavior. The empirical model treats the discrete choices of whether to itemize deductions and whether to hire professional tax advice, and the choice of how much time and money to spend, conditional on the discrete choices made. Simulations based on the econometric results suggest that significant resource saving could be expected from eliminating the system of itemized deductions, although no significant saving from changing to a single-rate tax structure can be confidently predicted. Results suggest that the Tax Reform Act of 1986 will, in the long run, decrease the use ofprofessional tax assistance, but its net effect on the use of taxpayer's own time is unclear.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68711/2/10.1177_109114218901700101.pd

Jets as a Probe of Dense Matter at RHIC
Jet quenching in the matter created in high energy nucleus-nucleus collisions
provides a tomographic tool to probe the medium properties. Recent experimental
results on jet production at the Relativistic Heavy-Ion Collider (RHIC) are
reviewed. Jet properties in p+p and d+Au collisions have been measured,
establishing the baseline for studying jet modification in heavy-ion
collisions. Current progress on detailed studies of high transverse momentum
production in Au+Au collisions is discussed, with an emphasis on dihadron
correlation measurements.Comment: 8 pages, 9 figures. Plenary talk given at 17th International

Unknown Rectal Lesions: A Case of Severe Proctitis Secondary to Mpox in the Setting of Concomitant HIV, Syphilis, HSV, and Chlamydia
Introduction:
Mpox emerged as a public health crisis with limited research describing co-occurring HIV and sexually transmitted infections (STIs). We present a case of severe proctitis secondary to Mpox with concomitant HIV (Human Immunodeficiency Virus), syphilis, HSV (Herpes Simplex Virus), and chlamydia and review presentation, diagnosis, treatment, and prevention of Mpox with concurrent STIs.
Case Presentation:
34-year-old male living with HIV (LWH) presenting with worsening rectal pain, multiple anal papules, and fever. His laboratory workup revealed simultaneous positive results for orthopoxvirus, chlamydia, and HSV-1 PCR. We initiated tecovirimat due to rectal involvement and uncontrolled pain. He subsequently developed lesions on hands as rectal pain improved. He completed tecovirimat treatment and the lesions cleared by outpatient follow-up.
Discussion:
Among published studies of Mpox patients, 40% were LWH, and a significant percent were found to have co-occurring gonorrhea (23%), chlamydia (20%), syphilis (8%), and HSV (1%) with presentations including fever (62%), lymphadenopathy (49%), malaise (39%), and rectal pain (25%). We recommend Mpox and full STI diagnostic testing for unknown anogenital lesions and early treatment should be considered. Early initiation of Tecovirimat treatment should be considered in severe disease, immune deficiency, or those at high-risk for serious sequelae, in accordance with CDC guidelines.
Learning Points: Identify the differential diagnosis for unknown rectal lesions Describe the clinical presentation of Mpox Summarize the diagnostic approach and interpretation of diagnostic results Identify treatment options and considerations by patient populations Review preventative strategies and high-risk populations for Mpox transmissio
