Giant Merkel Cell Carcinoma Masquerading as a Benign Cyst on the Buttock of an African American Man
Marissa J. Perman,Janelle M. King,Laurel L. Leithauser,Hugh M. Gloster
Case Reports in Oncological Medicine , 2011, DOI: 10.1155/2011/849767
Abstract: We report a case of a 60-year-old African American man who presented with a 4-year history of a previously asymptomatic, recently enlarging nodule on his left buttock, which was initially presumed to be an epidermoid cyst. Physical examination revealed a large, fixed, subcutaneous tumor, and a biopsy revealed merkel cell carcinoma. Immunohistochemical staining was positive for pankeratin, CAM 5.2, synaptophysin, and CD56 and negative for CK7, CK20, TTF-1, chromogranin, CD3, CD20, CD57, MART1, and HMB 45. The patient underwent wide local excision of the lesion with removal of the fascia overlying the gluteus and full body positron emission tomography (PET) and was found to have Stage IIb disease. He subsequently received adjuvant radiotherapy limited to the tumor bed at a dose of 60 gray.
An excursion approach to maxima of the Brownian Bridge
Mihael Perman,Jon A. Wellner
Mathematics , 2009, DOI: 10.1016/j.spa.2014.04.008
Abstract: Functionals of Brownian bridge arise as limiting distributions in nonparametric statistics. In this paper we will give a derivation of distributions of extrema of the Brownian bridge based on excursion theory for Brownian motion. Only the Poisson character of the excursion process will be used. Particular cases of calculations include the distributions of the Kolmogorov-Smirnov statistic, the Kuiper statistic, and the ratio of the maximum positive ordinate to the minumum negative ordinate.
The Spatial Variability and Temporal Dynamics of Soil Properties as Affected by Visitors’ Pressure in an Urban Park  [PDF]
Helena M. Zhevelev, Pariente Sarah, Atar Oz
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.48A2007

Soil properties and their tempo-spatial heterogeneity, affected by visitors’ pressure, season and soil depth, were studied in an urban park in Tel-Aviv. Soil was sampled twice yearly in wet and dry seasons. In each season soil was sampled from areas exposed to differing levels of visitors’ pressure (VP), and designated “no VP (Control)”, “High VP” and “Low VP”. The soil samples were taken from two depths. For each soil sample, moisture, organic matter and soluble-ion contents, pH, and electrical conductivity were determined. It was found that different properties were differently affected by VP, seasonal dynamics and soil depth: organic matter content, penetration depth and sodium concentration were the most sensitive to VP; Soil moisture did not respond to VP, but sharply reflected seasonal changes; Calcium and organic matter contents were significantly affected by the soil depth. The sensitivity of soil properties to VP increased from March to July, and the upper soil layer was more sensitive to seasonal dynamics and VP than the deeper layer. Some soil properties exhibited “spotty” patterns; others a “frontal” one. Organic matter content was completely controlled by VP at both depths and in both seasons, and could be used as an indicator of soil status in recreation areas. Visitors activities included trampling and other anthropogenic factors that enhanced the spatial changes and seasonal dynamics of soil properties. Based on these measurements the intensity of soil degradation and dynamics was evaluated and used to describe the soil status in an urban park.

A New Look at Generalized Means  [PDF]
Sarah M. Tooth, John A. Dobelman
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.76042
Abstract: Since antiquity, the relationships between 2-tuples and their Pythagorean means have been represented in geometric forms. In this paper, we extend the practice to generalized power means through new representations, and also to 3-tuples. These geometric forms give rise to new algebraic expressions for summary statistics of 2- and 3-tuples.
Use of Basal Serum Testosterone Level as Predictor for Poor Ovarian Response in Women with Unexplained Infertility Undergoing In Vitro Fertilization Cycle: Prospective Study  [PDF]

Open Journal of Obstetrics and Gynecology (OJOG) , 2018, DOI: 10.4236/ojog.2018.814153
Abstract: Background: Delayed pregnancy in women and marked increase in the numbers of older women who fail to respond to ovarian stimulation had been a significant issue. This study aims to assess the value of basal serum testosterone level as a predictor of ovarian response for induction of ovulation in women with unexplained infertility undergoing IVF (in vitro fertilization) cycle. Patients and Methods: A prospective study was conducted in Ain Shams University Maternity hospital Infertility Center during a period of time from October 2016 to June 2017. This study recruited 89 women. On day 2 or 3 of a spontaneous menstrual cycle of the included women within 3 months before fresh IVF cycle, basal hormonal (FSH, LH, estradiol, total testosterone) concentrations, AFC (antral follicle count) were performed. Using the Long-protocol for induction of ovulation, serial monitoring of ovarian response was assessed by transvaginal ultrasound. When the expected ovarian response was reached (at least three oocytes 17 mm), we gave trigger dose of HCG. Ultrasound guided oocyte aspiration was performed 34 -

Abstract: Modern culinary direction - molecular gastronomy is very complex, and the relative youth of that direction affects the ignorance of the matter by a large number of professionals and the general public. It is precisely this lack of matter which causes a number of disagreements between chefs and scientists, while there is a number of related debates about aspects of molecular gastronomy, especially in connection with a change in its gastronomic cuisine. The main focus of disagreement lies in the name of ''molecular'', which mostly leads to a misunderstanding, because of the identification with something microscopic. A very common mistake is to address this branch of gastronomy as a style of cooking, which she doesn't represent. The second mistake is naming its practical application of molecular cooking, molecular cuisine. Molecular gastronomy is a scientific discipline that studies food and asks questions and gives answers so far unanswered questions about gastronomy. Simply put, molecular gastronomy can be understood as a process of application of science in everyday cooking, and the application of molecular gastronomy in the kitchen. Modern man with his awareness made some chefs to reconsider the adoption of these radical ideas to accomplish the fusion of science and gastronomy. This idea is established as a full hit, because today the best restaurants in the world, the vast majority of those who have seen the benefits of these two joints before incompatible branches of human activity. As a culinary direction it quickly spread to Western Europe and North America, and it later spread to other parts of the world, but Croatia and neighboring countries are not one of them. Molecular gastronomy shows the trends of further progress, and in the future molecular gastronomy will be more prevalent and popular.

Abstract: CRM as a trend in business and business philosophy consists of a series of complex and diverse business resources such as: modern technological resources, information resources, human resources and all other procedural resources which serve to improve services to end user and customer.Tourism as a service industry which business is based on selling services, has found great benefits and advantages in using CRM. Different kinds of CRM applications and systems have become extremely popular in all sectors. Thus, in the tourism sector, CRM has become one of the most important strategy in attracting and increasing tourist arrivals, in filling the tourist facilities and in satisfying the needs of guests.The main goals of CRM are to attract tourists, to meet a maximum of tourists (a new guarantee of return and achieve the most efficient promotion), increase the number of tourists and achieve customer loyalty. It enables more efficient marketing and sales and it improves the overall tourism industry and services aimed at tourists and their preferences. Implementation of CRM systems is very demanding and requires commitment at all levels of the company. Very big problem is the integration of CRM systems with existing information systems in the enterprise. It is often impossible to implement without the use of qualified personnel and software that has the task of bridging the gulf between the CRM and existing information systems to create an integrated system. It is desirable that the companies have been devoting increased funding for implementation of new technologies and that systems, in a short period of time, can realize a return on investment and greatly improve the business performance of enterprises. CRM gives the expected results only if it is fully integrated strategically and operationally in the business and in the information system of tourist enterprise. The fact is that this process and business philosophy will become important in the future, and it will continuously improve its processes and relationships within the company, all in order to reduce operating costs, creating a detailed segmentation of the market and meet the needs of guests.
lociNGS: A Lightweight Alternative for Assessing Suitability of Next-Generation Loci for Evolutionary Analysis
Sarah M. Hird
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0046847
Abstract: Genomic enrichment methods and next-generation sequencing produce uneven coverage for the portions of the genome (the loci) they target; this information is essential for ascertaining the suitability of each locus for further analysis. lociNGS is a user-friendly accessory program that takes multi-FASTA formatted loci, next-generation sequence alignments and demographic data as input and collates, displays and outputs information about the data. Summary information includes the parameters coverage per locus, coverage per individual and number of polymorphic sites, among others. The program can output the raw sequences used to call loci from next-generation sequencing data. lociNGS also reformats subsets of loci in three commonly used formats for multi-locus phylogeographic and population genetics analyses – NEXUS, IMa2 and Migrate. lociNGS is available at https://github.com/SHird/lociNGS and is dependent on installation of MongoDB (freely available at http://www.mongodb.org/downloads). lociNGS is written in Python and is supported on MacOSX and Unix; it is distributed under a GNU General Public License.
Quantising general relativity using QED theory, an overview and extension
Sarah B. M. Bell
Physics , 2004,
Abstract: We summarise and discuss some of our previous results, which show that Bohr's theory of the one-electron atom may be derived from the theory underpinning Quantum ElectroDynamics (QED) or vice versa, and that General Relativity may also be derived from QED theory in the classical limit, if we use Newtonian mechanics in the right frame and self-similar tesseral hierarchies. We circumvent Newton's arguments against Descartes' vortex theory to show that the inverse square law for a force combined with the equation of circular motion and Bohr's quantisation of angular momentum may be derived from the vortex theory and Special Relativity. We remark on the electro-weak interaction, the number of dimensions needed, and their connection with tesseral hierarchies.
