Three-body recombination rates near a Feshbach resonance within a two-channel contact interaction model

We calculate the three-body recombination rate into a shallow dimer in a gas of cold bosonic atoms near a Feshbach resonance using a two-channel contact interaction model. The two-channel model naturally describes the variation of the scattering length through the Feshbach resonance and has a finite effective range. We confront the theory with the available experimental data and show that the two-channel model is able to quantitatively describe the existing data. The finite effective range leads to a reduction of the scaling factor between the recombination minima from the universal value of 22.7. The reduction is larger for larger effective ranges or, correspondingly, for narrower Feshbach resonances.Comment: 9 pages, 7 figure

Summary report to assist development of ecosystem flow recommendations for the Coast Fork and Middle Fork of the Willamette River, Oregon

Introduction The Willamette River Flow Project The Nature Conservancy (TNC) and the U. S. Army Corps of Engineers (USACE) are collaborating on a project to determine environmental flow requirements for the Willamette River and its tributaries and to design and test alternative flow releases from the dams that can meet these requirements. The project is part of the Sustainable Rivers Project (SRP), a national effort by TNC and USACE to investigate opportunities to change Corps Dam operations (“reoperate”) to achieve more ecologically sustainable flows, while maintaining or enhancing project benefits. Through the SRP, TNC and USACE have developed and tested a process for identifying and refining environmental flow objectives (Richter et. al. 2006). The process utilizes a series of steps to define environmental flow requirements, implement changes in operation of dams to meet those flow objectives, monitor and model the effects of those changes on both the river ecosystem and the operation of the dams, and refine over time. The Willamette River Flow Project is being conducted in conjunction with the USACE Willamette Floodplain Restoration Feasibility Study. This feasibility study is designed to identify opportunities to restore natural floodplain function in the Willamette River basin to provide ecosystem restoration, natural flood storage, and other benefits. The initial study phase has focused on the Coast and Middle Forks of the Willamette River. These subbasins contain 6 of the 13 dams in the Willamette system; their operation has implications for the operation of the other dams in the system. To date, the Floodplain Restoration Study has focused on two important aspects of the aquatic ecosystem: 1) identifying habitat, flow and water quality requirements for a variety of aquatic and floodplain species; and 2) describing and evaluating the current channel and floodplain morphological characteristics, and their changes from historic condition. Partners in the feasibility study include the Willamette Partnership, the Willamette Middle and Coast Fork Watershed councils, the Oregon Department of Fish and Wildlife, and The Nature Conservancy. There is also an inter-disciplinary expert and stakeholder group of approximately 20 federal, state and local entities plus private landowners that informs the process. The Willamette River Flow Project will build upon the Floodplain Restoration study by developing environmental flow requirements for the reaches downstream of the Corps dams and linking those flows to opportunities for stream channel and floodplain restoration, and to improvement in operation of the dams. Given the existing floodplain restoration study, the initial SRP efforts will use the Coast and Middle Forks and the mainstem Willamette immediately downstream of these tributaries as a pilot study that can be replicated in the rest of the Willamette system. River flows from both subbasins have been greatly affected by operation of the dams: 56% of the drainage area of the Coast Fork and 87% of the Middle Fork drain into USACE reservoirs. General effects of the reservoirs include reduced peak flows, lower spring flows, increased summer low flows, and infrequent bankfull and out-of-bank flows. The Willamette Flow Project partners anticipate the study will be expanded in the future to encompass the other major tributaries controlled by USACE dams.Prepared for Sustainable Rivers Project of the Nature Conservancy and the U.S. Army Corps of Engineers

Geriatric Rehabilitation as an Integral Part of Geriatric Medicine in the Nordic Countries

Neðst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinn View/OpenObjective: Firstly to outline the theoretical and practical framework for geriatric rehabilitation in Iceland and other Nordic countries and secondly to survey the scientific medical publications for evidence based geriatric rehabilitation. Methods: Brain storming on geriatric rehabilitation in a working group of Nordic teachers in geriatric medicine. Papers on scientific programs for geriatric rehabilitation from Internet sources were collected and analyzed. All articles describing randomized studies in geriatric rehabilitation were selected for overview. The papers were divided into four groups according to diseases, infirmity and resource settings; 1) stroke, 2) hip-fractures, 3) acute admissions and 4) programs conducted in nursing homes, day hospitals and home services. Results: A spectrum of biological and social events creates the conditions underlying most causes for illness and disability in old people. The process of established geriatric services promotes the efficiency of geriatric rehabilitation. The literature survey included 27 scientific studies (8586 patients) on randomized studies with valid endpoints. Geriatric rehabilitation programs for stroke patients in geriatric settings, six studies (1138 patients), reduced mortality and the need for nursing home placement but the outcome for ADL. Function and length of stay was more variable between the studies. The outcome of geriatric rehabilitation was even more decisive in the randomized hip-fracture studies, six studies (2171 patients). Eight studies were found comparing the outcome between acute admission of frail elderly to either geriatric (GEMU, GRU) or general medical wards. The outcome as regards to mortality rate at one year, placement to a nursing home, physical function, contentment with services, readmission rate and cost was all significantly better in the geriatric settings. Internal comparisons of geriatric programs in nursing homes, day hospitals and in home service, seven studies (1261 patient), revealed some differences in outcomes in function, contentment and costs. Conclusions: Specialized geriatric rehabilitation is complicated but effective when properly performed. Interdisciplinary teamwork, targeting of patients, comprehensive assessment and intensive and patient-targeted rehabilitation seem to characterize the most effective programs. Rehabilitation of frail elderly people poses a major challenge for the future and has to be developed further for the sake of quality of life of elderly people as well as for economic reasons.Markmið: Að gera úttekt á öldrunarendurhæfingu á Íslandi og öðrum Norðurlöndum, marka hinn hugmyndafræðilega grunn, tengja hann norrænum veruleika og taka saman vísindalegar niðurstöður um árangur öldrunarendurhæfingar.

Efimov three-body states on top of a Fermi sea

The stabilization of Cooper pairs of bound electrons in the background of a Fermi sea is the origin of superconductivity and the paradigmatic example of the striking influence of many-body physics on few-body properties. In the quantum-mechanical three-body problem the famous Efimov effect yields unexpected scaling relations among a tower of universal states. These seemingly unrelated problems can now be studied in the same setup thanks to the success of ultracold atomic gas experiments. In light of the tremendous effect of a background Fermi sea on two-body properties, a natural question is whether a background can modify or even destroy the Efimov effect. Here we demonstrate how the generic problem of three interacting particles changes when one particle is embedded in a background Fermi sea, and show that Efimov scaling persists. It is found in a scaling that relates the three-body physics to the background density of fermionic particles.Comment: 15 pages, 2 figures, 2 appendices, revised and updated version, in pres

Short-term effects of Vertical sleeve gastrectomy and Roux-en-Y gastric bypass on glucose homeostasis

The objective of this study was to compare the biochemical changes related to glucose tolerance and lipid metabolism in non-diabetic patients shortly after vertical sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). Non-diabetic women and men with morbid obesity were studied the day before and six days after SG (N = 15) or RYGB (N = 16). Patients completed an oral glucose tolerance test (OGTT; 75 g glucose) at both visits. SG and RYGB similarly improved fasting glucose homeostasis six days after surgery, with reduced glucose and insulin concentrations. The OGTT revealed differences between the two surgery groups that were not evident from the fasting serum concentrations. Postprandial (120 min) glucose and insulin concentrations were lower after RYGB but not after SG, whereas concentrations of glucagon-like peptide-1, peptide YY, glucagon and non-esterified fatty acids were elevated after both SG and RYGB. Fasting triacylglycerol concentration did not change after surgery, but concentrations of high density lipoprotein and low density lipoprotein cholesterols were reduced in both surgery groups, with no differences between the groups. To conclude, RYGB induced a more pronounced improvement in postprandial glucose homeostasis relative to SG, possibly due to improved insulin sensitivity rather than augmented insulin concentration.publishedVersio

Identifying Ligand Binding Conformations of the β2-Adrenergic Receptor by Using Its Agonists as Computational Probes

Recently available G-protein coupled receptor (GPCR) structures and biophysical studies suggest that the difference between the effects of various agonists and antagonists cannot be explained by single structures alone, but rather that the conformational ensembles of the proteins need to be considered. Here we use an elastic network model-guided molecular dynamics simulation protocol to generate an ensemble of conformers of a prototypical GPCR, β2-adrenergic receptor (β2AR). The resulting conformers are clustered into groups based on the conformations of the ligand binding site, and distinct conformers from each group are assessed for their binding to known agonists of β2AR. We show that the select ligands bind preferentially to different predicted conformers of β2AR, and identify a role of β2AR extracellular region as an allosteric binding site for larger drugs such as salmeterol. Thus, drugs and ligands can be used as "computational probes" to systematically identify protein conformers with likely biological significance. © 2012 Isin et al

Surgery for extraforaminal lumbar disc herniation: a single center comparative observational study

Background Surgery on extraforaminal lumbar disc herniation (ELDH) is a commonly performed procedure. Operating on this type of herniation is known to come with more difficulties than on the frequently seen paramedian lumbar disc herniation (PLDH). However, no comparative data are available on the effectiveness and safety of this operation. We sought out to compare clinical outcomes at 1 year following surgery for ELDH and PLDH. Methods Data were collected through the Norwegian Registry for Spine Surgery (NORspine). The primary outcome measure was change at 1 year in the Oswestry Disability Index (ODI). Secondary outcome measures were quality of life measured with EuroQol 5 dimensions (EQ-5D); and numeric rating scales (NRSs). Results Data of a total of 1750 patients were evaluated in this study, including 72 ELDH patients (4.1%). One year after surgery, there were no differences in any of the patient reported outcome measurements (PROMs) between the two groups. PLDH and ELDH patients experienced similar changes in ODI (- 30.92 vs. - 34.00, P = 0.325); EQ-5D (0.50 vs. 0.51, P = 0.859); NRS back (- 3.69 vs. - 3.83, P = 0.745); and NRS leg (- 4.69 vs. - 4.46, P = 0.607) after 1 year. The proportion of patients achieving a clinical success (defined as an ODI score of less than 20 points) at 1 year was similar in both groups (61.5% vs. 52.7%, P = 0.204). Conclusions Patients operated for ELDH reported similar improvement after 1 year compared with patients operated for PLDH.Scientific Assessment and Innovation in Neurosurgical Treatment Strategie
