Compact storage ring to search for the muon electric dipole moment
We present the concept of a compact storage ring of less than 0.5 m orbit
radius to search for the electric dipole moment of the muon () by
adapting the "frozen spin" method. At existing muon facilities a statistics
limited sensitivity of d_\mu \sim 5 \times 10^{-23} \ecm can be achieved
within one year of data taking. Reaching this precision would demonstrate the
viability of this novel technique to directly search for charged particle EDMs
and already test a number of Standard Model extensions. At a future, high-power
muon facility a statistical reach of d_\mu \sim 5 \times 10^{-25} \ecm seems
realistic with this setup.Comment: improved for submission; minor modification
Can Changing the Value System and Re-aligning the Financial Structure of the Institution Prevent Clinician Burnout?
Growing clinician burnout in the U.S. is nearing public health crisis levels. Each year, 400 physicians commit suicide, a rate more than twice that of the general population. Nearly one-third of nurses are emotionally exhausted. The traditional culture of health care - characterized by hierarchy, autonomy, competition, and individualism - has created an environment that makes it difficult for physicians to ask for help or seek care when they need it. The effects of this problem extend beyond the individual health care worker - burnout has been shown to lead to impaired professionalism, high staff turnover, a decrease in patient satisfaction, and an increase in medical errors. How are we to care for others if we cannot care for ourselves? Clearly, we must do a better job of creating environments that strengthen resilience and support the well-being of clinicians and other health care workers. Dr. Kirch will present a framework outlining the domains influencing clinician well-being, including the work environment, learning environment, and personal and professional factors. He will then delve into causal factors in each of these domains, including administrative and regulatory burdens, power differentials and mistreatment, and isolation and work-life imbalance. He will also examine the positive forces at work in each domain that promote wellness, social support, and group connectedness. Finally, Dr. Kirch will review the growing national momentum behind efforts to identify and implement evidence-based solutions promoting clinician well-being and combating burnout, depression, and suicide among U.S. health care workers. While much work remains to be done to create a healthy and resilient clinician workforce, addressing this problem at a national level will make a difference in the lives of clinicians, in the cultures of our institutions, and ultimately, in the outcomes of our patients.https://openworks.mdanderson.org/hrc_burnout_presentations/1007/thumbnail.jp
Do internal capital markets in business groups mitigate firms' financial constraints?
We develop a new rationale for capital allocation in business groups’ internal capital markets. We show
that productivity and pledgeable income jointly drive capital allocation within an internal capital market.
In financially constrained business groups, an efficient internal capital market can allocate marginal funds
to firms that have high pledgeability of income because of a multiplier effect: a dollar of internal funds
generates a bigger increase in investment. This result has important implications for the business group
affiliation strategy. Whether or not a financially constrained but highly productive firm will benefit from
group affiliation depends on its borrowing capacity vis-Ă -vis other affiliates
Study of the adsorption of methyl iodide and molecular iodine on clean uranium and uranium dioxide surfaces by means of X-ray photoelectron (XPS) and Auger electron spectroscopy (AES)
Experimental study of 199Hg spin anti-relaxation coatings
We report on a comparison of spin relaxation rates in a Hg
magnetometer using different wall coatings. A compact mercury magnetometer was
built for this purpose. Glass cells coated with fluorinated materials show
longer spin coherence times than if coated with their hydrogenated homologues.
The longest spin relaxation time of the mercury vapor was measured with a
fluorinated paraffin wall coating.Comment: 9 pages, 6 figures, submitted to JINS

Measurement of the Transverse Polarization of Electrons Emitted in Free Neutron Decay
Both components of the transverse polarization of electrons emitted in the
beta-decay of polarized, free neutrons have been measured. The T-odd, P-odd
correlation coefficient quantifying the component perpendicular to the decay
plane defined by neutron polarization and electron momentum, was found to be
R=0.008 +/- 0.015 +/-0.005. This value is consistent with time reversal
invariance, and significantly improves limits on the relative strength of
imaginary scalar couplings in the weak interaction. The value obtained for the
correlation coefficient associated with the electron polarization component
contained within the decay plane N=0.056 +/- 0.011 +/- 0.005, agrees with the
Standard Model expectation, providing an important sensitivity test of the
experimental setup.Comment: 4 pages, 4 figure
