Deceleration and Trapping of SrF Molecules.

We report on the electrostatic trapping of neutral SrF molecules. The molecules are captured from a cryogenic buffer-gas beam source into the moving traps of a 4.5-m-long traveling-wave Stark decelerator.

A supersonic laser ablation beam source with narrow velocity spreads.

A supersonic beam source for SrF and BaF molecules is constructed by combining the expansion of carrier gas (a mixture of 2% SF and 98% argon) from an Even-Lavie valve with laser ablation of a barium/strontium metal target at a repetition rate of 10 Hz. Molecular beams with a narrow translational velocity spread are produced at relative values of Δv/v = 0.053(11) and 0.

HP-Xe to go: Storage and transportation of hyperpolarized (129)Xenon.

Recently the spin-lattice relaxation time T1 of hyperpolarized (HP)-(129)Xe was significantly improved by using uncoated and Rb-free storage vessels of GE180 glass. For these cells, a simple procedure was established to obtain reproducible wall relaxation times of about 18 h. Then the limiting relaxation mechanism in pure Xe is due to the coupling between the nuclear spins and the angular momentum of the Xe-Xe van-der-Waals-molecules.

Two of a Kind--The Biosynthetic Pathways of Chlorotonil and Anthracimycin.

Chlorotonil A is a novel polyketide isolated from the myxobacterium Sorangium cellulosum So ce1525 that features a unique gem-dichloro-1,3-dione moiety. It exhibits potent bioactivity, most notably against the problematic malaria pathogen Plasmodium falciparum in the nanomolar range. In addition, strong antibacterial and moderate antifungal activity were determined.

Effect of soil temperature on optical frequency transfer through unidirectional dense-wavelength-division-multiplexing fiber-optic links.

Results of optical frequency transfer over a carrier-grade dense-wavelength-division-multiplexing (DWDM) optical fiber network are presented. The relation between soil temperature changes on a buried optical fiber and frequency changes of an optical carrier through the fiber is modeled. Soil temperatures, measured at various depths by the Royal Netherlands Meteorology Institute (KNMI) are compared with observed frequency variations through this model.

Precise determination of the unperturbed 8B neutrino spectrum.

A measurement of the final state distribution of the (8)B β decay, obtained by implanting a (8)B beam in a double-sided silicon strip detector, is reported here. The present spectrum is consistent with a recent independent precise measurement performed by our collaboration at the IGISOL facility, Jyväskylä [O. S.

Search for Lorentz and CPT violation effects in Muon spin precession.

The spin precession frequency of muons stored in the (g-2) storage ring has been analyzed for evidence of Lorentz and CPT violation. Two Lorentz and CPT violation signatures were searched for a nonzero delta omega a(=omega a mu+ - omega a mu-) and a sidereal variation of omega a mu+/-). No significant effect is found, and the following limits on the standard-model extension parameters are obtained: bZ = -(1.

New method of measuring electric dipole moments in storage rings.

A new highly sensitive method of looking for electric dipole moments of charged particles in storage rings is described. The major systematic errors inherent in the method are addressed and ways to minimize them are suggested. It seems possible to measure the muon EDM to levels that test speculative theories beyond the standard model.

Measurement of the negative muon anomalous magnetic moment to 0.7 ppm.

The anomalous magnetic moment of the negative muon has been measured to a precision of 0.7 ppm (ppm) at the Brookhaven Alternating Gradient Synchrotron. This result is based on data collected in 2001, and is over an order of magnitude more precise than the previous measurement for the negative muon.

Measurement of the positive muon anomalous magnetic moment to 0.7 ppm.

A higher precision measurement of the anomalous g value, a(mu)=(g-2)/2, for the positive muon has been made at the Brookhaven Alternating Gradient Synchrotron, based on data collected in the year 2000. The result a(mu(+))=11 659 204(7)(5)x10(-10) (0.7 ppm) is in good agreement with previous measurements and has an error about one-half that of the combined previous data.

Upper airway epithelial structural changes in obstructive sleep-disordered breathing.

The etiology of upper airway collapsibility in patients with snoring and obstructive sleep apnea (OSA) remains unclear. Structural mucosal changes could be contributory factors. The objective of this study was to determine whether pathologic changes in the epithelium or the epithelial-connective tissue interface are present in patients with snoring and/or OSA by means of scanning electron microscopy and immunohistochemistry.

Morphological studies of the optic canal.

Background: In some cases of closed head injuries after minor blunt trauma, an amaurosis can occur. Our knowledge concerning the pathophysiological mechanisms of traumatic optic neuropathy is limited. The aim of this study is to analyze the morphology of the optic canal in order to understand the effect of mechanical forces in the optic canal and the consecutive injuries.

Test of CPT and Lorentz invariance from muonium spectroscopy.

Following a suggestion from Kostelecký et al., we evaluated a test of CPT and Lorentz invariance from the microwave spectroscopy of muonium. Hamiltonian terms beyond the standard model violating CPT and Lorentz invariance would contribute frequency shifts deltanu(12) and deltanu(34) to nu(12) and nu(34), the two transitions involving muon spin flip, which were precisely measured in ground state muonium in a strong magnetic field of 1.

Precise measurement of the positive muon anomalous magnetic moment.

A precise measurement of the anomalous g value, a(mu) = (g-2)/2, for the positive muon has been made at the Brookhaven Alternating Gradient Synchrotron. The result a(mu+) = 11 659 202(14) (6) x 10(-10) (1.3 ppm) is in good agreement with previous measurements and has an error one third that of the combined previous data.

The validity of the ICD-10 classification of recurrent affective disorders: do endogenous and psychogenic depressions form a homogeneous diagnostic group?

Fifty-five hospital-treated patients with the ICD-10 diagnosis of 'recurrent depressive episode(s)' were classified according to the Newcastle Depressive Diagnostic Scale as having either psychogenic (n = 25) or endogenous (n = 30) depression and interviewed using several inventories on personality and psychopathology (Composite International Diagnostic Interview, Symptom Check List, Inventory of Interpersonal Problems, IIP, NEO Five-Factor Personality Inventory, Social Adjustment Scale, Questionnaire of the Motivation to Seek Psychotherapy). Except for the IIP, individual subscales disclosed significant differences between the two groups. In light of these results, the grouping of these two disorders into one diagnostic group in the ICD-10 is critically discussed.

Measurement of the 1s-2s energy interval in muonium.

The 1s-2s interval has been measured in the muonium (&mgr;(+)e(-)) atom by Doppler-free two-photon pulsed laser spectroscopy. The frequency separation of the states was determined to be 2 455 528 941.0(9.

[The joint capsule of the cricoarytenoid joint: biomechanical and clinical aspects].

Background: Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament may occur as a consequence of laryngeal trauma and joint disease. Little is known to date about the cricoarytenoid joint capsule and its role in joint pathology.

Methods: The present study analyses the structure of the cricoarytenoid joint capsule by means of histological, immunohistochemical, and scanning electron microscopical methods.

Motivation to seek psychotherapy in patients with recurrent depressive disorder.

Fifty-five hospital-treated patients with the ICD-10 diagnosis of recurrent depressive episode(s) were classified according to the Newcastle Depressive Diagnostic Scale as having either psychogenic (n = 25) or endogenous (n = 30) depression and interviewed using the Composite International Diagnostic Interview and the Questionnaire for Assessment of Motivation to Seek Psychotherapy. The two groups were found to differ significantly from one another in two Motivation to Seek Psychotherapy subscales ("layman's etiology" and "general expectations from therapy"). The motivation to seek psychotherapy was greater in patients with psychogenic depression than in patients with endogenous depression.

The cricoarytenoid joint capsule and its relevance to endotracheal intubation.

Unlabelled: Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament may occur as a consequence of endotracheal intubation. Little is known about the cricoarytenoid joint capsule and its role in intubation. We investigated the joint capsules of 48 cricoarytenoid joints by means of gross anatomy microscopy, histology, and scanning electron microscopy; 30 unfixed cadaver larynges were also subjected to attempts to simulate traumata such as those that may occur during intubation trials.
