Long term stability of sensation thresholds from 10 millisecond pulses of 2.01 micrometer laser light

2013 Summer.Includes bibliographical references.Current methods for diagnosing and evaluating efficacy for treatment of diabetic neuropathy either give only subjective data or are invasive. However, the use of laser induced sensations to evaluate threshold sensations gives precisely quantifiable and reproducible stimulus and is 100% non-invasive. In this study we evaluated whether or not laser sensation thresholds were stable in 12 human subjects over a four month period of time. Subjects' hands and feet were exposed over eight different exposure sessions to 10 ms pulses of laser light produced by a 50 W Tm: YAG laser system. Sensation threshold values (in mJ/mm2) were determined for each session and compared by regression analysis. The results showed an upward trend in sensation thresholds over time in the majority of the subject's hands and feet, indicating that laser sensation thresholds are not stable over time. Subject desensitization to the sensation over time combined with too short a time between exposures, or variations in baseline skin temperature of the exposure site due to changes in weather are discussed as possible causes of the upward trend. Finally, suggestions are made for future studies to include a study over a longer period of time with more time between exposure sessions and more subjects as well as a study where the exposure sites are heated/cooled to a standardized baseline temperature prior to each exposure session

A Long Spell of Uncertainity

We find ourselves in a period of sustained economic uncertainty. Today, like 6 months ago, the U.S. economy is on the brink of a recession. Weakness in lending activity, coupled with weakness in the housing sector and related manufacturing industries has stymied economic growth since late 2007. At times, recession seems imminent. But, the official measures, such as quarterly gross domestic product, do not clearly signal that the economy is contracting. Further, prices are rising rapidly for food and energy. That is the uncertainty. Will 2008 be remembered as a recession year, or as a period of disappointing but slow growth? And, will 2008 be known as the year when inflation reignited in America. In some sense, the answer does not matter. The United States and its citizens already are experiencing some of the consequences of recession, and of higher inflation. Job counts are declining and unemployment is rising. Many face the prospect of losing their homes. Prices including food and energy are rising 2% faster than in most recent years. But, of course, the answer matters quite a lot. If the U.S. economy falls into recession, or if a recession has already begun, job losses will accelerate and unemployment will rise sharply. The real estate and financial markets may spiral down faster. There is also a risk that prices increases will accelerate if inflation in food and energy spreads into wage inflation impacting a broad spectrum of sectors. Our view is that the economy will avoid both a significant recession and rapid inflation. Strong exports will encourage growth, and consumers and the financial sector will slowly work their way through their current difficulties. Inflation largely will be contained to the food and energy sectors. But, the scenario is far from rosy. We expect weak economic growth through 2008 and early 2009, and elevated inflation rates through 2010. In particular, we expected annual growth in real GDP of 1.1% in 2008, 1.7% in 2009. GDP growth rates only returns to trend growth of 2.8% in 2010. Inflation will hit 4.0% in 2008, and will be well above 2% in subsequent years, at 2.6% in 2009, and 2.7% in 2010. A significant slowdown will be avoided because the weak dollar will encourage strong exports, and because consumer spending will expand modestly despite a weak employment situation and high energy prices. Consumer confidence has declined rapidly but consumer spending should stay steady thanks to lower interest rates, and in the very short-term, federal government rebate checks. Current high energy prices also are expected to stabilize, and therefore, will not cause even further strain on consumer spending for other goods and services. This relatively positive scenario naturally assumes that the U.S. economy will avoid other major dislocations. The economy may fall into a significant recession if there are other major disruptions in the financial system that limit access to capital. Inflation may spike further if oil prices rise or additional weather causes further increases in food prices

Ocean Bottom Seismometer Augmentation in the North Pacific (OBSANP) - cruise report

The Ocean Bottom Seismometer Augmentation in the North Pacific Experiment (OBSANP, June-July, 2013, R/V Melville) addresses the coherence and depth dependence of deep-water ambient noise and signals. During the 2004 NPAL Experiment in the North Pacific Ocean, in addition to predicted ocean acoustic arrivals and deep shadow zone arrivals, we observed "deep seafloor arrivals" (DSFA) that were dominant on the seafloor Ocean Bottom Seismometer (OBS) (at about 5000m depth) but were absent or very weak on the Distributed Vertical Line Array (DVLA) (above 4250m depth). At least a subset of these arrivals correspond to bottomdiffracted surface-reflected (BDSR) paths from an out-of-plane seamount. BDSR arrivals are present throughout the water column, but at depths above the conjugate depth are obscured by ambient noise and PE predicted arrivals. On the 2004 NPAL/LOAPEX experiment BDSR paths yielded the largest amplitude seafloor arrivals for ranges from 500 to 3200km. The OBSANP experiment tests the hypothesis that BDSR paths contribute to the arrival structure on the deep seafloor even at short ranges (from near zero to 4-1/2CZ). The OBSANP cruise had three major research goals: a) identification and analysis of DSFA and BDSR arrivals occurring at short (1/2CZ) ranges in the 50 to 400Hz band, b) analysis of deep sea ambient noise in the band 0.03 to 80Hz, and c) analysis of the frequency dependence of BR and SRBR paths. On OBSANP we deployed a 32 element VLA from 12 to 1000m above the seafloor, eight short-period OBSs and four long-period OBSs and carried out a 15day transmission program using a J15-3 acoustic source.Funding was provided by the Office of Naval Research under contract #'s N00014-10-1-0987 and N00014-10-1-051

Ocean Bottom Seismometer Augmentation of the Philippine Sea Experiment (OBSAPS) cruise report

The Ocean Bottom Seismometer Augmentation to the Philippine Sea Experiment (OBSAPS, April-May, 2011, R/V Revelle) addresses the coherence and depth dependence of deep-water ambient noise and signals. During the 2004 NPAL Experiment in the North Pacific Ocean, in addition to predicted ocean acoustic arrivals and deep shadow zone arrivals, we observed "deep seafloor arrivals" that were dominant on the seafloor Ocean Bottom Seismometer (OBS) (at about 5000m depth) but were absent or very weak on the Distributed Vertical Line Array (DVLA) (above 4250m depth). These "deep seafloor arrivals" (DSFA) are a new class of arrivals in ocean acoustics possibly associated with seafloor interface waves. The OBSAPS cruise had three major research goals: a) identification and analysis of DSFAs occurring at short (1/2CZ) ranges in the 50 to 400Hz band, b) analysis of deep sea ambient noise in the band 0.03 to 80Hz, and c) analysis of the frequency dependence of BR and SRBR paths as a function of frequency. On OBSAPS we deployed a fifteen element VLA from 12 to 852m above the seafloor, four short-period OBSs and two long-period OBSs and carried out an 11.5day transmission program using a J15-3 acoustic source.Funding was provided by the Office of Naval Research under Contract Nos.

Concept for a Future Super Proton-Proton Collider

Following the discovery of the Higgs boson at LHC, new large colliders are being studied by the international high-energy community to explore Higgs physics in detail and new physics beyond the Standard Model. In China, a two-stage circular collider project CEPC-SPPC is proposed, with the first stage CEPC (Circular Electron Positron Collier, a so-called Higgs factory) focused on Higgs physics, and the second stage SPPC (Super Proton-Proton Collider) focused on new physics beyond the Standard Model. This paper discusses this second stage.Comment: 34 pages, 8 figures, 5 table
