Controlling the Big Stick: Theodore Roosevelt and theCuban Crisis of 1906
Theodore Roosevelt is unquestionably one of the giants of American political history. A veritable dynamo both in and out of office, Roosevelt was nothing less than a turn-of-the-century Renaissance man who combined a scholar\u27s keen intellect with a rough-and-tumble spirit of adventure. As this Nation\u27s twenty-sixth President, Roosevelt may be best remembered for developing his own corollary to James Monroe\u27s famous doctrine of 1823 and then using American military muscle to bring its tenets to life
Stabilized Singlets in Supergravity as a Source of the mu-parameter
Within the context of supergravity-coupled supersymmetry, fields which are
gauge and global singlets are usually considered anathema. Their vacuum
expectation values are shifted by quadratically divergent tadpole diagrams
which are cutoff at the Planck scale, destabilizing the classical potential and
driving the singlet field to large values. We demonstrate a new and generic
mechanism which stabilizes the singlet in the presence of an extended gauge
symmetry. Such a symmetry will be broken down to the Standard Model by the
supergravity interactions near the scale of spontaneous supersymmetry-breaking
in the hidden-sector (about 10^{10-11} GeV). The resulting singlet expectation
value is stabilized and naturally of order the gravitino mass, providing
therefore a weak-scale mass for the Higgs fields of the supersymmetric Standard
Model (a "mu-parameter"). The resulting low-energy theory is the minimal
supersymmetric Standard Model, with all new fields decoupling at the
intermediate scale.Comment: 9 pages, LaTe
Saccadic Eye Movement Characteristics in Adult Niemann-Pick Type C Disease: Relationships with Disease Severity and Brain Structural Measures
Niemann-Pick Type C disease (NPC) is a rare genetic disorder of lipid metabolism. A parameter related to horizontal saccadic peak velocity was one of the primary outcome measures in the clinical trial assessing miglustat as a treatment for NPC. Neuropathology is widespread in NPC, however, and could be expected to affect other saccadic parameters. We compared horizontal saccadic velocity, latency, gain, antisaccade error percentage and self-paced saccade generation in 9 adult NPC patients to data from 10 age-matched controls. These saccadic measures were correlated with appropriate MRI-derived brain structural measures (e.g., dorsolateral prefrontal cortex, frontal eye fields, supplemental eye fields, parietal eye fields, pons, midbrain and cerebellar vermis) and with measures of disease severity and duration. The best discriminators between groups were reflexive saccade gain and the two volitional saccade measures. Gain was also the strongest correlate with disease severity and duration. Most of the saccadic measures showed strongly significant correlations with neurophysiologically appropriate brain regions. While our patient sample is small, the apparent specificity of these relationships suggests that as new diagnostic methods and treatments become available for NPC, a broader range of saccadic measures may be useful tools for the assessment of disease progression and treatment efficacy.No external funding was received for this study.

Practical lessons learned for assessing and treating bipolar disorder via telehealth modalities during the COVID-19 pandemic
We briefly frame challenges and steps to overcoming those challenges in delivering care for patients with bipolar disorder via telehealth or telephone during COVID-19. Telehealth provides an invaluable opportunity to provide care for patients even under circumstances of social isolation. The issues discussed in this debate are intended to guide and assist clinicians, both in assessment and intervention, in adjusting to the use of virtual care for patients with bipolar disorder
