Allocation of Gaming Licenses and Establishment of Bid Processes: The Case of Kansas, 2008 and 2009
This paper looks at the recent history of allocation of exclusive franchise or limited franchise casino licenses in jurisdictions throughout the world and comments on their strengths and weaknesses as well as successes and failures of various strategies that have been undertaken. The paper then examines the Kansas legalization and bidding process that emerged between 2007 and 2009 as a case study in evaluating the effectiveness of various principles that had emerged via the legislation and subsequent procedural decisions. The authors offer the opinion that many of the principles and processes developed in Kansas were based on those that had been implemented in successful bid processes in other jurisdictions. In spite of the inability or unwillingness by several winning bidders to act upon their awarded bids in Kansas in 2008 and the subsequent thinning of the bidding pool in 2009, primarily related to the severe economic downturn that affected the general economy and the casino industry in particular, the authors suggest the Kansas model provides an excellent template for other jurisdictions to develop and to execute similar processes in the future
IGR J00234+6141 : a new INTEGRAL source identified as an Intermediate polar
Following an extensive survey of the galactic plane by the INTEGRAL
satellite, new hard X-ray sources are discovered with a significant fraction of
Cataclysmic Variables (CVs) among them. We report here the identification of
one of these hard X-ray sources, IGR J00234+6141, as an accreting magnetic
white dwarf of intermediate polar type. We analyse the high energy emission of
the INTEGRAL source using all available data and provide complementary optical
photometric and spectroscopic data obtained respectively in August and October
2006. Based on a refined INTEGRAL position, we confirm the proposed optical
identification. We clearly detect the presence of a 564 s periodic optical
modulation that we identify as the rotation of the white dwarf. The analysis of
the optical spectrum also demonstrates that the emission lines show a
modulation in radial velocity with an orbital period of Porb = (4.033 +/-
0.005) hr. The two periodicities indicate that IGR00234+6141 is a magnetic CV
of the intermediate polar type. This is one of the faintest and hardest sources
of this type detected by INTEGRAL. This confirms earlier conclusions that IPs
contribute significantly to the population of galactic X-ray sources and
represent a significant fraction of the high energy background.Comment: 6 pages, 7 figures, accepted for publication in A&
Using the Rosat Catalogue to find Counterparts for Unidentified Objects in the 1st Fermi/LAT Catalogue
There are a total of 1451 gamma-ray emitting objects in the Fermi Large Area
Telescope First Source Catalogue. The point source location accuracy of
typically a few arcminutes has allowed the counterparts for many of these
sources to be found at other wavelengths, but even so there are 630 which are
described as having no plausible counterpart at 80% confidence. In order to
help identify the unknown objects, we have cross-correlated the positions of
these sources with the Rosat All Sky Survey Bright Source Catalogue. In this
way, for Fermi sources which have a possible counterpart in soft X-rays, we can
use the, much smaller, Rosat error box to search for identifications. We find a
strong correlation between the two samples and calculate that there are about
60 sources with a Rosat counterpart. Using the Rosat error boxes we provide
tentative associations for half of them, demonstrate that the majority of these
are either blazars or blazar candidates and give evidence that most belong to
the BL Lac class. Given that they are X-ray selected and most are high
synchrotron peaked objects, which indicates the presence of high energy
electrons, these sources are also good candidates for TeV emission, and
therefore good probes of the extragalactic background light.Comment: 9 pages, 1 figure; Accepted for publication in MNRA
Cone-Beam Computed Tomographic Assessment of the Mandibular Condylar Volume in Different Skeletal Patterns: A Retrospective Study in Adult Patients
The aim of this study was to assess the condylar volume in adult patients with different
skeletal classes and vertical patterns using cone‐beam computed tomography (CBCT). CBCT scans
of 146 condyles from 73 patients (mean age 30 12 years old; 49 female, 24 male) were selected from
the archive of the Department of Dentistry and Maxillofacial Surgery of Fondazione IRCCS Ca’
Granda, Milan, Italy, and retrospectively analyzed. The following inclusion criteria were used: adult
patients; CBCT performed with the same protocol (0.4 mm slice thickness, 16 22 cm field of view,
20 s scan time); no systemic diseases; and no previous orthodontic treatments. Three‐dimensional
cephalometric tracings were performed for each patient, the mandibular condyles were segmented
and the relevant volumes calculated using Mimics Materialize 20.0 software (Materialise, Leuven,
Belgium). Right and left variables were analyzed together using random‐intercept linear regression
models. No significant association between condylar volumes and skeletal class was found. On the
other hand, in relation to vertical patterns, the mean values of the mandibular condyle volumes in
hyperdivergent subjects (688 mm3) with a post‐rotation growth pattern (625 mm3) were smaller than in
hypodivergent patients (812 mm3) with a horizontal growth pattern (900 mm3). Patients with an increased
divergence angle had smaller condylar volumes than subjects with normal or decreased mandibular
plane divergence. This relationship may help the clinician when planning orthodontic treatment
Unveiling the nature of INTEGRAL objects through optical spectroscopy. IV. A study of six new hard X-ray sources
We present further results from our ongoing optical spectrophotometric
campaign at the Astronomical Observatory of Bologna in Loiano (Italy) on
unidentified hard X-ray sources detected by INTEGRAL. We observed
spectroscopically the putative optical counterparts of the INTEGRAL sources IGR
J00234+6141, IGR J01583+6713, IGR J06074+2205, IGR J13091+1137 and IGR
J20286+2544. We find that the first two are Galactic objects, namely a
Cataclysmic Variable at a distance of about 300 pc and a Be/X transient
High-Mass X-ray Binary (HMXB) located at about 6.4 kpc, respectively, whereas
the last one is identified with MCG +04-48-002, a Starburst/HII galaxy at
redshift z = 0.013 hiding a Seyfert 2 nucleus. We identify IGR J13091+1137 as
the (likely Seyfert 2 type) active nucleus of galaxy NGC 4992, which we
classify as an X-ray Bright, Optically Normal Galaxy; this is the first example
of this type of object to be detected by INTEGRAL, and one of the closest of
this class. We moreover confirm the possible Be/X nature of IGR J06074+2205,
and we estimate it to be at a distance of about 1 kpc. We also reexamine the
spectrum of the z = 0.087 elliptical radio galaxy PKS 0352-686, the possible
counterpart of the INTEGRAL source IGR J03532-6829, and we find that it is a BL
Lac. Physical parameters for these sources are also evaluated by discussing our
findings in the context of the available multiwavelength information. These
identifications further stress the importance of INTEGRAL in the study of the
hard X-ray spectrum of Active Galactic Nuclei, HMXBs and Cataclysmic Variables.Comment: 11 pages, 3 figures, 2 tables, accepted for publication on A&A, main

Cytoreductive surgery for patients with recurrent epithelial ovarian carcinoma.
OBJECTIVE: This study aims to identify favorable preoperative characteristics and examine the impact of secondary cytoreductive surgery on survival for patients with recurrent epithelial ovarian carcinoma.
METHODS: Patients who underwent cytoreductive surgery for recurrent epithelial ovarian cancer were identified in our surgical database for the period 1988-2004. Patient charts were reviewed and data collected regarding patient demographics, surgical management, preoperative evaluation, perioperative complications, and oncologic outcome.
RESULTS: Eighty-five patients met eligibility criteria. Preoperative factors that correlated with improved survival were disease-free interval of greater than 12 months (por=1 cm (p
CONCLUSION: When selecting patients for secondary cytoreduction, the most significant preoperative factors are disease-free interval and success of a prior cytoreductive effort. Once secondary cytoreductive surgery is attempted, the most important factor for improved survival is optimal cytoreduction. Of equal importance is counseling regarding the significant risk for bowel surgery, colostomy, and complications

Confidence in value-based choice
Decisions are never perfect, with confidence in one's choices fluctuating over time. How subjective confidence and valuation of choice options interact at the level of brain and behavior is unknown. Using a dynamic model of the decision process, we show that confidence reflects the evolution of a decision variable over time, explaining the observed relation between confidence, value, accuracy and reaction time. As predicted by our dynamic model, we show that a functional magnetic resonance imaging signal in human ventromedial prefrontal cortex (vmPFC) reflects both value comparison and confidence in the value comparison process. Crucially, individuals varied in how they related confidence to accuracy, allowing us to show that this introspective ability is predicted by a measure of functional connectivity between vmPFC and rostrolateral prefrontal cortex. Our findings provide a mechanistic link between noise in value comparison and metacognitive awareness of choice, enabling us both to want and to express knowledge of what we want

Dietary supplements for the management of COVID-19 symptoms
SARS-CoV-2, the etiological agent of COVID-19, caused a pandemic in 2020, which is only recently slowing down. The symptoms of COVID-19 range from cough to fever and pneumonia and may persist beyond the active state of the infection, in a condition called post-COVID syndrome. The aim of this paper is to review the relationship between COVID-19 and nutrition and to discuss to most up-to-date dietary supplements proposed for COVID-19 treatment and prevention. Nutrition and nutritional dysregulations, such as obesity and malnutrition, are prominent risk factors for severe COVID-19. These factors exert anti-inflammatory and proinflammatory effects on the immune system, thus exacerbating or reducing the immunological response against the virus. As for the nutritional habits, the Western diet induces a chronic inflammatory state, whereas the Mediterranean diet exerts anti-inflammatory effects and has been proposed for ameliorating COVID-19 evolution and symptoms. Several vaccines have been researched and commercialized for COVID-19 prevention, whereas several drugs, although clinically tested, have not shown promising effects. To compensate for the lack of treatment, several supplements have been recommended for preventing or ameliorating COVID-19 symptoms. Thus, it is critical to review the dietary supplements proposed for COVID-19 treatment. Supplements containing α-cyclodextrin and hydroxytyrosol exhibited promising effects in several clinical trials and reduced the severity of the outcomes and the duration of the infection. Moreover, a supplement containing hydroxytyrosol, acetyl L-carnitine, and vitamins B, C, and D improved the symptoms of patients with post-COVID syndrome
