Authors: Zhang Hong , Kong Vic , Huang Ke , Jin Jian-Yue 
Published: February 2016

Purpose: To present our experiences in understanding and minimizing bowtie-filter crescent artifacts and bowtie-filter normalization artifacts in a clinical cone beam computed tomography system. Methods: Bowtie-filter position and profile variations during gantry rotation were studied. Two previously proposed strategies (A and B) were applied to the clinical cone beam computed tomography system to correct bowtie-filter crescent artifacts. Physical calibration and analytical approaches were used to minimize the norm phantom misalignment and to correct for bowtie-filter normalization artifacts. A combined procedure to reduce bowtie-filter crescent artifacts and bowtie-filter normalization artifacts was proposed and tested on a norm phantom, CatPhan, and a patient and evaluated using standard deviation of Hounsfield unit along a sampling line. Results: The bowtie-filter exhibited not only a translational shift but also an amplitude variation in its projection profile during gantry rotation. Strategy B was better than strategy A slightly in minimizing bowtie-filter crescent artifacts, possibly because it corrected the amplitude variation, suggesting that the amplitude variation plays a role in bowtie-filter crescent artifacts. The physical calibration largely reduced the misalignment-induced bowtie-filter normalization artifacts, and the analytical approach further reduced bowtie-filter normalization artifacts. The combined procedure minimized both bowtie-filter crescent artifacts and bowtie-filter normalization artifacts, with Hounsfield unit standard deviation being 63.2, 45.0, 35.0, and 18.8 Hounsfield unit for the best correction approaches of none, bowtie-filter crescent artifacts, bowtie-filter normalization artifacts, and bowtie-filter normalization artifacts + bowtie-filter crescent artifacts, respectively. The combined procedure also demonstrated reduction of bowtie-filter crescent artifacts and bowtie-filter normalization artifacts in a CatPhan and a patient. Conclusion: We have developed a step-by-step procedure that can be directly used in clinical cone beam computed tomography systems to minimize both bowtie-filter crescent artifacts and bowtie-filter normalization artifacts.

A multimodal discourse analysis of the textual and logical relations in marketing texts written by international undergraduate students
Authors: Alyousef Hesham Suleiman 
Published: February 2016

AbstractThematic progression and the composition of information value contribute to the development of well-structured meaningful text. Discourse-based research of the textual features has been confined to language learning and workplace contexts, and in particular advertising and marketing research. However, no published study has explored and analysed the multimodal textual and the logic-semantic features in tertiary marketing texts. This case study employed a Systemic Functional Multimodal Discourse Analysis (SF-MDA) to investigate and compare thematic progression patterns and composition of information value in five business marketing plan reports. It also aimed to investigate the logico–semantic expansions between the visual semiotic resources and the text surrounding them. The SF-MDA of the marketing plan texts is underpinned by Halliday’s (1994) systemic functional linguistics, Kress and van Leeuwen’s (1996) composition of information value and Martinec and Salway’s (2005) system for multimodal discourse analysis of logico–semantic relations. The findings of the SF-MDA revealed the extensive use of Theme reiteration pattern, followed by linear thematic progression pattern. Although multiple-Theme pattern was minimally employed, disciplinary-specific uses of this pattern in marketing discourse emerged. The findings suggest that the students have managed professional workplace practices by showing their understandings of marketing as part of overall business management. A number of other interesting findings related to textual and logico–semantic relations that exist between the tables and the graphs and the accompanying text were revealed. The SF-MDA of informational choices in the marketing texts extends Kress and van Leeuwen’s (1996) functional interpretations of visual artefacts in terms of compositional zones. As the intersemiotic logic-semantic relations between graphs and tables and the orthographic texts surrounding them play a vital role in marketing discourse, tutors can introduce ways of expanding the meaning-making potential in these semiotic resources. Other pedagogical implications for the teaching and learning of writing are presented, particularly in the teaching of English for Business students.

Purpose To assess the prevalence and severity of neurocognitive impairment in adult survivors of pediatric CNS tumors and to examine associated treatment exposures. Patients and Methods Participants included 224 survivors of CNS tumors who were treated at St Jude Children's Research Hospital (current median age [range], 26 years [19 to 53 years]; time from diagnosis, 18 years [11 to 42 years]) and completed neurocognitive testing. Information on cranial radiation therapy (CRT) doses and parameters of delivery were abstracted from medical records. The prevalence of severe impairment (ie, at least two standard deviations below normative mean) was compared across radiation treatment groups (no CRT, focal irradiation, craniospinal irradiation) using the χ2 test. Log-binomial models were used to estimate risk ratios (RRs) and corresponding 95% CIs for severe impairment. Results In multivariable models, craniospinal irradiation was associated with a 1.5- to threefold increased risk of severe impairment compared with no CRT (eg, intelligence: RR = 2.70; 95% CI, 1.37 to 5.34; memory: RR = 2.93; 95% CI, 1.69 to 5.08; executive function: RR = 1.74; 95% CI, 1.24 to 2.45). Seizures were associated with impaired academic performance (RR = 1.48; 95% CI, 1.02 to 2.14), attention (RR = 1.54; 95% CI, 1.12 to 2.13), and memory (RR = 1.44; 95% CI, 1.04 to 1.99). Hydrocephalus with shunt placement was associated with impaired intelligence (RR = 1.78; 95% CI, 1.12 to 2.82) and memory (RR = 1.42; 95% CI, 1.03 to 1.95). Differential follow-up time contributed to variability in prevalence estimates between survivors treated with older nonconformal and those treated with more contemporary conformal radiation therapy methods. Neurocognitive impairment was significantly associated with lower educational attainment, unemployment, and nonindependent living. Conclusion Survivors of pediatric CNS tumors are at risk of severe neurocognitive impairment in adulthood. The prevalence of severe impairment is greater than expected in the general population, even in the absence of CRT, and is associated with disrupted attainment of adult social milestones.
GnRH Pulse Frequency Control of Fshb Gene Expression Is Mediated via ERK1/2 Regulation of ICER

Published: February 2016

AbstractThe pulsatile release of GnRH regulates the synthesis and secretion of pituitary FSH and LH. Two transcription factors, cAMP-response element-binding protein (CREB) and inducible cAMP early repressor (ICER), have been implicated in the regulation of rat Fshb gene expression. We previously showed that the protein kinase A pathway mediates GnRH-stimulated CREB activation. We hypothesized that CREB and ICER are activated by distinct signaling pathways in response to pulsatile GnRH to modulate Fshb gene expression, which is preferentially stimulated at low vs high pulse frequencies. In the LβT2 gonadotrope-derived cell line, GnRH stimulation increased ICER mRNA and protein. Blockade of ERK activation with mitogen-activated protein kinase kinase I/II (MEKI/II) inhibitors significantly attenuated GnRH induction of ICER mRNA and protein, whereas protein kinase C, calcium/calmodulin-dependent protein kinase II, and protein kinase A inhibitors had minimal effects. GnRH also stimulated ICER in primary mouse pituitary cultures, attenuated similarly by a MEKI/II inhibitor. In a perifusion paradigm, MEKI/II inhibition in LβT2 cells stimulated with pulsatile GnRH abrogated ICER induction at high GnRH pulse frequencies, with minimal effect at low frequencies. MEKI/II inhibition reduced GnRH stimulation of Fshb at high and low pulse frequencies, suggesting that the ERK pathway has additional effects on GnRH regulation of Fshb, beyond those mediated by ICER. Indeed, induction of the activating protein 1 proteins, cFos and cJun, positive modulators of Fshb transcription, by pulsatile GnRH was also abrogated by inhibition of the MEK/ERK signaling pathway. Collectively, these studies indicate that the signaling pathways mediating GnRH activation of CREB and ICER are distinct, contributing to the decoding of the pulsatile GnRH to regulate FSHβ expression.
Using the mouse to model human disease: increasing validity and reproducibility
Authors: Justice Monica J. , Dhillon Paraminder 
Published: February 2016

ABSTRACT
Experiments that use the mouse as a model for disease have recently come under scrutiny because of the repeated failure of data, particularly derived from preclinical studies, to be replicated or translated to humans. The usefulness of mouse models has been questioned because of irreproducibility and poor recapitulation of human conditions. Newer studies, however, point to bias in reporting results and improper data analysis as key factors that limit reproducibility and validity of preclinical mouse research. Inaccurate and incomplete descriptions of experimental conditions also contribute. Here, we provide guidance on best practice in mouse experimentation, focusing on appropriate selection and validation of the model, sources of variation and their influence on phenotypic outcomes, minimum requirements for control sets, and the importance of rigorous statistics. Our goal is to raise the standards in mouse disease modeling to enhance reproducibility, reliability and clinical translation of findings.
The body in between, the dissociative experience of trauma
Authors: Walker Anna 
Published: February 2016

Abstract
In ‘The autonomy of the affect’ Brian Massumi wrote of the gap between affective and cognitive registering of the traumatic experience. Affect theorists and neuroscientists have long shared the notion of a gap between the somatic response to a traumatic event and the appraisal of the affective situation. This article develops theories on dissociation or nothingness, where nothingness is a measurement of the space between the affective and the cognitive registering of a traumatic event. It explores the concept of two different systems, one a ‘conscious automatic’ system and the other an ‘intensity system’ that exists outside of normal physiological sequencing, beyond narration, and therefore incapable of integrating into memory systems.

Fiscal Constraints In The European Union – When More Is Less?
Authors: Macsim Florin-Alexandru , Oprea Florin 
Published: February 2016

Abstract
This paper examines the implications of fiscal rules measured through the Fiscal Rules Index and fiscal institutions that supervise fiscal policies on key aspects of fiscal policies such as public debt and budget deficits. Our goal was to identify the specific links between fiscal rules, institutions and fiscal policies, to support any rethinking of public policy matters. Our results confirm that the government’s consolidated debt is influenced by both fiscal rules and institutions. Through this research we have showed that an increased number of institutions and fiscal rules is closely related to an increase in public debt levels. We explained this influence by stating that cause may consist in not having one strong and independent institution, but more institutions more or less independent that divide key responsibilities. Also our results indicate that budget deficits aren’t influenced either by supervising institutions or fiscal rules.
Economic Insecurity as Systemic Risk
Authors: Pârţachi Ion , Gârlă Eugeniu 
Published: February 2016

Abstract
Difficulties related to the problem of evaluating the economic security / insecurity, including the threshold of economic security / insecurity, namely the impossibility of giving an analytical description of a criterion entirely made up of a set of indicators describing the degree of economic security / insecurity, makes more and more researchers, including the authors, to seek indirect ways of finding solutions, for example considering systemic risk., as a measure of evaluation. Thus, starting from a new approach, and given the specific components of systemic risk to financial stability: the banking sector, corporate sector, public sector, volume of credits, economic activity index the threshold vector of economic security / insecurity can be developed. The study shows that systemic risk can be used to measure the threshold of economic security /insecurity.
Endorsements’ Effects of one Branded Service on Attitude, Purchase Intention and Intention of Recommendation Towards the Service Category
Authors: Cara Corina , Tocila Tudor 
Published: February 2016

Abstract
The study focuses on the effectiveness of endorsement strategies in the beauty service industry. We refer an effective endorsement strategy as a strategy where the endorser is perceived as trustful and we assume that trustworthiness leads to an attitudinal or behavioural change.
This quantitative research aims to identify the changes in attitude, purchase intention and intention of recommendation based on the perceived credibility derived from three different sources of endorsement - celebrities, experts and typical satisfied consumers.
426 subjects participated on an online survey. Their attitudes and intentions related to the service category were measured before and after they were exposed to an ad layout for one branded service.
All the tracked changes were significant, leading endorsement to make positive changes in purchase and recommendation intentions, but negative changes in attitude. Differences between consumers and nonconsumers and between males and females were analysed.
An Insight Regarding Economic Growth and Monetary Policy in Romania
Authors: Mera Valentina , Pop Silaghi Monica 
Published: February 2016

Abstract
This study introduces some aspects regarding the link between monetary policy and economic growth, through a rule well known in the literature which is named Taylor’s rule and through the concept of sacrifice ratio which encompasses the impact of the cost of disinflation on the economic growth of a country. In this paper, we rely on estimates of the growth of potential GDP of the National Bank of Romania for the period 2003-2006 while for the period 2007-2012 we rely on the estimates reported by the International Monetary Fund. Thus, we carry a deterministic exercise for computing the interest rate on the period 2003-2012 as depicted from the Taylor’s rule and we compare it with the effective monetary policy interest rate used by the National Bank of Romania. In the same time, we calculate the sacrifice ratio for the period 1997-2013 so as to be able to form an opinion regarding the cost of disinflation and its comparison with the typical estimates for larger time spans and for other countries.

Preliminary evaluation of the effectiveness of visible implant elastomer and coded wire tags for tagging young-of-the-year Atlantic sturgeon, Acipenser oxyrinchus
Authors: Kapusta Andrzej , Duda Arkadiusz , Wiszniewski Grzegorz , Kolman Ryszard 
Published: February 2016

Abstract
The aim of the study was to determine the retention rates of visible implant elastomer (VIE) and coded wire tags (CWT) and the impact tagging had on the growth of Atlantic sturgeon, Acipenser oxyrinchus Mitchill, during an eight-week rearing period under laboratory conditions. Two size groups of young-of-the-year (YOY) sturgeon were used in the study. The tagging was not found to have a significant impact on the final total length or body weight or the condition coefficient of the sturgeon from either size group. Sturgeon survival in the different groups ranged from 90.6 to 100%. Mortality was not noted until two (CWT) and four (VIE) weeks following tagging and was probably not linked to tagging. The retention rate for VIE tags implanted in the rostrum in both size groups was 100%, while for tags implanted at the base of the pectoral fin was 93.5%. The retention of CWT in the smaller fish was 90%, and in the larger sturgeon it was 100%. Tagging small sturgeon with CWT and VIE is minimally invasive, and it did not impact the growth or condition of the tagged fish.
The spt-crank for ordinary partitions
Authors: Chen William Y. C. , Ji Kathy Q. , Zang Wenston J. T. 
Published: February 2016

Abstract

The spt-function spt(n) was introduced by Andrews as the weighted counting of partitions of n with respect to the number of occurrences of the smallest
part. Andrews, Garvan and Liang defined the spt-crank of an S-partition which leads to combinatorial interpretations of the congruences of spt(n) modulo 5 and 7. Let NS
(m,n) denote the net number of S-partitions of n with spt-crank m. Andrews, Garvan and Liang showed that NS
(m,n) is nonnegative for all integers m and positive integers n, and they asked the question of
finding a combinatorial interpretation of NS
(m,n). In this paper, we introduce the structure of doubly marked partitions and define the spt-crank of a doubly marked partition. We show that the number NS
(m,n) can be interpreted as the number of doubly marked partitions of n with spt-crank m. Moreover, we
establish a bijection between marked partitions of n and doubly marked
partitions of n. A marked partition is defined by Andrews, Dyson and Rhoades
as a partition with exactly one of the smallest parts marked.
They consider it a challenge to find a definition of the
spt-crank of a marked partition so that the set of
marked partitions of

5
n

$5n$

+ 4 and 7n + 5 can be divided into five and seven equinumerous classes.
The definition of spt-crank for doubly marked partitions and the bijection between the marked partitions and doubly marked partitions in principle lead to a solution to the problem of Andrews, Dyson and Rhoades.

AbstractWe introduce the notions of an absolutely non-homomorphic function, a minimal function (farthest from homomorphisms) and a bent function, and prove that the class of bent functions coincides with the class of absolutely non-homomorphic functions, a function is uniquely determined by the distances to homomorphisms with shifts, and that in the primary case the bent functions are absolutely minimal.

On the analysis of fuzzy information graphs

Published: February 2016

AbstractWe suggest a mathematical model of information search with fuzzy logic. We give elementary properties of this model such as a criterion for admissibility of an information graph and a criterion for completeness of a basic set. We describe a method to go from a precise search problem to a fuzzy one and give conditions for a solution of the precise problem to be a solution of the corresponding fuzzy problem.
