Photoproduction evidence for and against hidden-strangeness states near 2 GeV
Experimental evidence from coherent diffractive proton scattering has been
reported for two narrow baryonic resonances which decay predominantly to
strange particles. These states, with masses close to 2.0 GeV would, if
confirmed, be candidates for hidden strangeness states with unusual internal
structure. In this paper we examine the literature on strangeness
photoproduction, to seek additional evidence for or against these states. We
find that one state is not confirmed, while for the other state there is some
mild supporting evidence favoring its existence. New experiments are called
for, and the expected photoproduction lineshapes are calculated.Comment: 9 pages, RevTex, five postscript figures, submitted to PR
Prepare your indicators: Economics imperialism on the shores of law and development
This article explores the influence of economics on the demand for, and deployment of, indicators in the context of the World Bank's investment climate campaign. This campaign is characterised by an emphasis on marketisation, mathematisation and quantification, which are respectively the normative, analytical and empirical approaches of choice in mainstream economics. The article concludes that economics generally, and indicators in particular, have brought a certain discipline and energy to the field of law and development. But this ‘progress’ has often been at the expense of non-economic values and interests, and even of our ability to mourn their loss
Access to Health Care Through Catamount Health; Do Providers Know Enough to Refer?
Background: On November 1, 2007, Vermont launched ‘Catamount Health,’ a state-sponsored private insurance plan. The goal: to close the gap between privately insured and Medicaid insured Vermonters. Previous programs such as Dr. Dynasaur and VHAP were already in place to care for children and low-income residents respectively. Now, under the umbrella title of “Green Mountain Care,” Catamount Health joins them. Catamount Health offers private coverage through either Blue Cross/Blue Shield of VT or MVP Health Care, the cost of which is offset by the state according to income level and household size. To qualify for Catamount, an individual must have an income of at least 1.6 million dollars to fund a large-scale advertising campaign on television, radio, newspaper, and on foot. Following this campaign, there is a high likelihood that Vermonters will bring questions and concerns about Catamount to their physician offices and community leaders, emphasizing the importance of a well-educated provider.https://scholarworks.uvm.edu/comphp_gallery/1021/thumbnail.jp
Obtaining sigma --> gamma gamma Width from Nucleon Polarizabilities
We propose a new method that fixes the coupling to two photons of the
recently found lightest QCD resonance, the sigma. This coupling provides
crucial information for discriminating the yet unknown nature of this special
state. Our method uses available data on the nucleon polarizabilities together
with analyticity and unitarity. Taking into account all the uncertainties, our
result is Gamma_{pole}= 1.2 +- 0.4 keV.Comment: 7 pages, 1 figure, Invited Talk given by J.P. at 14th International

Paris COP 21: Power that Speaks the Truth?
© 2016 Informa UK Limited, trading as Taylor & Francis Group In this paper, I set out some of the key aspects of the Paris COP 21 Climate Change Agreement. The Paris Agreement was initially reported as a major success. However, this was in so far as many thought any kind of agreement at all was unlikely, and because the Agreement includes Article 2: an aspiration to maintain average global temperature increases to significantly less than 2°C. I then ask the question: if the Paris Agreement is a success of sorts, has anything fundamental changed in order to translate the conditional success of achieving an agreement into an actual success that will realise the goals of the Agreement? I address this in terms of early assessment of trends and the Nationally Determined Contributions, how responsibility is positioned in the Agreement, and the political economy context, which has called forth the need for an agreement
f0(980) meson as a K bar K molecule in a phenomenological Lagrangian approach
We discuss a possible interpretation of the f0(980) meson as a hadronic
molecule - a bound state of K and bar K mesons. Using a phenomenological
Lagrangian approach we calculate the strong f0(980) to pi pi and
electromagnetic f0(980) to gamma gamma decays. The compositeness condition
provides a self-consistent method to determine the coupling constant between f0
and its constituents, K and bar K. Form factors governing the decays of the
f0(980) are calculated by evaluating the kaon loop integrals. The predicted
f0(980) to pi pi and f0(980) to gamma gamma decay widths are in good agreement
with available data and results of other theoretical approaches.Comment: 21 pages, 11 figures, revised version accepted for publication in

Transcranial direct current stimulation in the treatment of visual hallucinations in Charles Bonnet syndrome: A randomized placebo-controlled crossover trial.
Objective
To investigate the potential therapeutic benefits and tolerability of inhibitory transcranial direct current stimulation (tDCS) on the remediation of visual hallucinations in Charles Bonnet Syndrome (CBS).
Design
Randomized, double-masked(blind), placebo-controlled crossover trial.
Participants
Sixteen individuals diagnosed with CBS secondary to visual impairment caused by eye disease experiencing recurrent visual hallucinations.
Intervention
All participants received four consecutive days of active and placebo cathodal stimulation (current density: 0.29mA/cm2) to the visual cortex (Oz) over two defined treatment weeks, separated by a four-week wash-out period.
Main Outcome Measures
Ratings of visual hallucination frequency and duration following active and placebo stimulation, accounting for treatment order, using a 2x2 repeated measures model. Secondary outcomes included impact ratings of visual hallucinations and electrophysiological measures.
Results
When compared to placebo treatment, active inhibitory stimulation of visual cortex resulted in a significant reduction in the frequency of visual hallucinations measured by the North East Visual Hallucinations Interview, with a moderate-to-large effect size. Impact measures of visual hallucinations improved in both placebo and active conditions suggesting support and education for CBS may have therapeutic benefits. Participants who demonstrated greater occipital excitability on electroencephalography assessment at the start of treatment were more likely to report a positive treatment response. Stimulation was found to be tolerable in all participants with no significant adverse effects reported, including no deterioration in pre-existing visual impairment.
Conclusions
Findings indicate that inhibitory tDCS of visual cortex may reduce the frequency of visual hallucinations in people with CBS, particularly individuals who demonstrate greater occipital excitability prior to stimulation. tDCS may offer a feasible, novel intervention option for CBS with no significant side effects, warranting larger scale clinical trials to further characterize its efficacy
Investigation of structural brain changes in Charles Bonnet Syndrome
Background and objectives
In Charles Bonnet Syndrome (CBS), visual hallucinations (VH) are experienced by people with sight loss due to eye disease or lesional damage to early visual pathways. The aim of this cross-sectional study was to investigate structural brain changes using magnetic resonance imaging (MRI) in CBS.
Methods
Sixteen CBS patients, 17 with eye disease but no VH, and 19 normally sighted people took part. Participants were imaged on a 3T scanner, with 1 mm resolution T1 weighted structural imaging, and diffusion tensor imaging with 64 diffusion directions.
Results
The three groups were well matched for age, sex and cognitive scores (MMSE). The two eye disease groups were matched on visual acuity. Compared to the sighted controls, we found reduced grey matter in the occipital cortex in both eye disease groups. We also found reductions of fractional anisotropy and increased diffusivity in widespread areas, including occipital tracts, the corpus callosum, and the anterior thalamic radiation. We did not find any significant differences between the eye disease participants with VH versus without VH, but did observe a negative association between hippocampal volume and VH severity in the CBS group.
Discussion
Our findings suggest that although there are cortical and subcortical effects associated with sight loss, structural changes do not explain the occurrence of VHs. CBS may relate instead to connectivity or excitability changes in brain networks linked to vision
Fine-mapping identifies multiple prostate cancer risk loci at 5p15, one of which associates with TERT expression
Associations between single nucleotide polymorphisms (SNPs) at 5p15 and multiple cancer types have been reported. We have previously shown evidence for a strong association between prostate cancer (PrCa) risk and rs2242652 at 5p15, intronic in the telomerase reverse transcriptase (TERT) gene that encodes TERT. To comprehensively evaluate the association between genetic variation across this region and PrCa, we performed a fine-mapping analysis by genotyping 134 SNPs using a custom Illumina iSelect array or Sequenom MassArray iPlex, followed by imputation of 1094 SNPs in 22 301 PrCa cases and 22 320 controls in The PRACTICAL consortium. Multiple stepwise logistic regression analysis identified four signals in the promoter or intronic regions of TERT that independently associated with PrCa risk. Gene expression analysis of normal prostate tissue showed evidence that SNPs within one of these regions also associated with TERT expression, providing a potential mechanism for predisposition to disease
