Abstract
This paper introduces a novel code called two dimensional Pascal’s triangle zero cross correlation (2D-PTZCC) for spectral/spatial coding with its structure of the corresponding system to implement in spectral amplitude coding optical code division multiple access (SAC-OCDMA) systems The novel code is derived from a one dimensional zero cross correlation (1D-ZCC) code using Pascal’s triangle rule. The analytical results prove that the proposed code has totally removed the multiple access interference (MAI), in addition the phase induced intensity noise (PIIN) influence is highly reduced due to the zero cross correlation (ZCC) property. Comparing with the recent developed two-dimensional codes like 2D multi diagonal (2D-MD), 2D dynamic cyclic shift (2D-DCS), 2D diluted perfect difference (2D-DPD) and 2D perfect difference (2D-PD) codes for the same code length. The results of simulation show that the suggested code improve the system capacity and increase the number of simultaneous users reaches 29 % and 64 % comparing to 2D-DPD and 2D-PD codes, respectively. As well, it supplies higher signal power and data bit rates whereas it saves effective source power around −0.81dBm for 2D-DCS and 2D-DPD codes and consumes minor light spectral width. The passage from 1D to 2D ameliorated 1.68 times the system capacity and saved around

Abstract

Background
Recent studies have discussed the application of wrist circumference as an easy-to-use predictor of general and abdominal obesity. The aim of the current study is to evaluate the association of wrist circumference with generalized and abdominal obesity and to determine its sex- and age-specific optimal cutoff points in association with generalized and abdominal obesity in a national sample of pediatric population.

Methods
This nationwide survey was conducted among 14,880 students, aged 6–18 years, selected through a multistage, random cluster sampling method from rural and urban areas of 30 provinces in Iran from 2011 to 2012. Anthropometric indices (weight, height, wrist circumference, waist circumference [WC], hip circumference [HC]) were measured by standard protocols using calibrated instruments. Body mass index (BMI) and waist-to-height ratio (WHtR) were calculated. By considering the area under the curve (AUC) of the receiver operator characteristic (ROC) curves, we evaluated the association of wrist circumference with obesity indices and determined its sex- and age-specific optimal cutoff points in association with obesity. AUC: 0.5, AUC: 0.5–0.65 and AUC: 0.65–1.0 were interpreted as equal to chance, moderately and highly accurate tests, respectively.

Results
Overall, 13,486 children and adolescents with a mean age of 12.47±3.36 years completed the study (participation rate of 90.6%). In both genders, wrist circumference had a significant correlation with anthropometric measures including weight, height, BMI, WC, HC and WHtR. In all age groups and both genders, wrist circumference performed relatively well in classifying individuals into overweight (AUC: 0.67–0.75, p<0.001), generalized obesity (AUC: 0.81–0.85, p<0.001) and abdominal obesity (AUC: 0.82–0.87, p<0.001).

Conclusions
Wrist circumference is suggested to be a useful index for assessing excess weight in the pediatric age group. Its easy measurement without the need of calculation ratios might make it as a routine measurement in daily clinical practice and in large epidemiological studies.
Is the hemolysis index always suitable for monitoring phlebotomy performance?
Authors: Lippi Giuseppe , Mattiuzzi Camilla , Cadamuro Janne 
Published: May 2018

AbstractThe new generation of clinical chemistry and coagulation analyzers is equipped with technical features allowing a systematic check of sample quality, including an assessment of the so-called HIL (“hemolysis”, “icterus”, “lipemia”) indices. These measures enable an accurate and reproducible assessment of sample hemolysis in serum or plasma, hence the hemolysis index (H-index) is now also increasingly used for monitoring and benchmarking phlebotomy performance. Reliable evidence attests that intravascular hemolysis is not such a rare phenomenon, and its prevalence may be especially higher in geographical areas where congenital hemolytic diseases are endemic, as well as in healthcare settings where patients with acquired hemolytic disorders are more frequently visited or hospitalized. It is hence conceivable that monitoring phlebotomy performance based on the rate of hemolyzed specimens received by the laboratory may not be so straightforward, provided that specimens drawn from patients with intravascular hemolysis can be identified and excluded from the analysis. The aim of this article is to provide an overview of potential drawbacks in using the H-index alone for monitoring phlebotomy performance, and to offer potential solutions to improve its efficiency for this scope. We therefore suggest that the H-index may only be used for purposes of benchmarking phlebotomy performance when the overall number of diagnoses of hemolytic diseases or the haptoglobin values measured by the laboratories are comparable across different healthcare settings or geographic areas.
Growth suppression of glioma cells using HDAC6 inhibitor, tubacin
Authors: Yin Changjiang , Li Pibao 
Published: May 2018

Abstract
In cancer research, autophagy has been revealed as one of the major ways to maintain the metabolism of cancer cells, including glioma cells, through protein degradation. Meanwhile, autophagy is also regarded as a kind of mechanism to protect glioma cells from a harmful stimulus, such as chemical and radiation treatment. So, the inhibition of autophagy may be very helpful in curing glioma. This study aimed to determine the effect of autophagic inhibition on glioma cells using tubacin, a specific inhibitor of histone deacetylase 6(HDAC6). According to the results, tubacin inhibited the growth of both U251 and LN229 cells, which was accompanied by lower HDAC6 activity and accumulated autophagosome. The inhibition of HDCA6 also led to accumulation of autophagosome and death of glioma cells. Moreover, the combined treatment of tubacin and temozolomide, an alkylating agent used to treat glioblastoma, induced more severe glioma cell death. Thus, it can be concluded that inhibition of HDAC6 suppressed growth and drug resistance of glioma cells in-vitro through autophagic suppression and blocking of fusion of autophagosome and lysosome.

TMP properties and refining conditions in a CD82 chip refiner. Part I: Step changes of process variables, description of the tests
Authors: Ferritsius Rita , Ferritsius Olof , Hill Jan , Karlström Anders , Eriksson Karin 
Published: May 2018

Abstract
The study explores how changes in process variables, residence time and pulp consistency in refining influence the pulp properties. The equipment utilized in this study was a conical disc chip refiner (RGP82CD) producing thermomechanical pulp (TMP). The focus was on the ratio between tensile index and specific energy consumption. Pulp properties were measured for composite pulp samples taken from the refiner blow line. Residence times and pulp consistencies were estimated by use of the extended entropy model. This showed that the CD-refiner, with the flat and conical refining zone, has a process performance similar to that of a two-stage refiner set-up, and that the consistency in both refining zones is of high importance. Comparing different periods revealed that even if the values of measured blow line consistency are similar, significant differences in the estimated consistency in the flat zone can prevail. Therefore, only monitoring blow line consistency is not enough. Specifically, it was found that the pulp consistency after the flat zone could be very high, considerably higher than in the blow line, and this could have negative effects on tensile index and fibre length.
Impact of non-uniform water absorption on water-interference print mottle in offset printing
Authors: Thorman Sofia , Ström Göran , Gane Patrick A. C. 
Published: May 2018

AbstractPrint mottle is a serious and yet common print defect in offset printing. An imbalance between the feed of fountain solution and the ability of the paper substrate to absorb and transport this water away from the surface can cause moisture/water interference problems. In the study presented here, we have investigated the uniformity of aqueous absorption and coating structure of pilot-coated papers with different types and dosages of dispersants and linked this to print mottle and uncovered areas (UCA). In earlier studies, the print quality of these papers indicated that a moderate addition of excess dispersant caused ink refusal, ink-lift-off (ink-surface adhesion failure) and water-interference mottle when printing at elevated fountain feed. In the present study, we have shown that a majority of the samples with uneven water/moisture absorption and an uneven burn-out reflectance tended to have more severe printing problems related to surface-moisture/water.An aqueous staining technique was used to characterise the absorption non-uniformities. This method has been developed previously with focus on absorption of flexographic water-based inks but can clearly give relevant information also for offset printing, when it comes to moisture/water interference mottle.
Improved Propagation Techniques to Enhance the Productivity of Banana (Musa spp.)
Authors: Tumuhimbise Robooni , Talengera David 
Published: May 2018

Abstract
The objective of this article is to provide information on pertinent propagation techniques for increased banana productivity. Banana, a very important crop in many tropical and subtropical countries of the world, is propagated with extreme difficulties. Its ordinary propagation technique of using suckers directly detached from a mother plant is limited by low multiplication rates and propensity of disseminating pests and diseases, which culminates in reduced banana productivity. Improved propagation techniques such as mother plant stripping, decapitation and mini-corms that increase the number of suckers are also somewhat deficient for large scale seed production and quality. Consequently, tissue and cell culture methods have been developed to address some of the challenges of seed quantity and quality although they are yet to be widely adopted. In this detailed review that includes results from hard-to-find literature, we discuss the traditional and modern methods of banana propagation, their benefits and limitations. Specifically, tissue culture stands out as the most prolific method of delivering high quantity and quality seed in banana. Its applicability, however, is limited by high costs of production and a need for skilled personnel and specialized equipment. It is imperative that to build a sustainable and viable banana seed production system, a multiplication scheme that combines two or more multiplication methods including tissue culture for cleaning the seed stock is utilized. The information provided gives premise for interventions to alleviate the problems of low banana seed availability, quantity and quality.
When “Questions“ are not Questions. Inferences and Conventionalization in Spanish But-Prefaced Partial Interrogatives
Authors: Ehmer Oliver , Rosemeyer Malte 
Published: May 2018

Abstract
The present paper analyzes the discourse-pragmatic function of introducing Spanish qué ‘what’- interrogatives with the concessive connective pero ‘but’. In some contexts, a pero-preface contributes to the interpretation of the interrogative as the realization of an interactional challenge rather than a request for information (e.g. an information question). We explore the inferential processes by which the peropreface leads to an interpretation of the interrogative as an interactional challenge and try to demonstrate that this challenge function of pero-prefaced qué-interrogatives may not only achieved ‘ad hoc’ by a local combination of the constitutive elements, but also by conventionalized form-function associations that developed diachronically. In a first step, we analyze pero-prefaced qué-interrogatives in a corpus of spoken Present Day Spanish. There are three main functions of pero-prefaces: to signal that a previous answer to the same interrogative is insufficient, to insist on an answer to a previously unattended request, or to challenge an immediately preceding action by an interlocutor. Using methodology from variationist linguistics, we identify entrenched patterns of pero-prefaced qué-interrogatives that have conventionalized the challenge function. In a second step, we conduct a diachronic variationist analysis of the development of Spanish pero-prefaced qué-interrogatives between 1700 and 1975, testing the hypothesis that the challenge reading developed later than the question reading. Our results show that due to their largely monological nature, the same inferential processes cued by pero lead to different discourse functions in historical texts. Over time, however, the use of pero-prefaced interrogatives started to become more likely in constructed dialogues. We argue that this change reflects an ongoing conventionalization of the challenge function in pero-prefaced interrogatives in spoken language.
Investigating Inferences in Sequences of Action: The Case of Claiming “Just-Now” Recollection with Oh That’s Right
Authors: Küttner Uwe-A. 
Published: May 2018

Abstract
This paper offers an exploratory Interactional Linguistic account of the role that inferences play in episodes of ordinary conversational interaction. To this end, it systematically reconsiders the conversational practice of using the lexico-syntactic format oh that’s right to implicitly claim “just-now” recollection of something previously known, but momentarily confused or forgotten. The analyses reveal that this practice typically occurs as part of a larger sequential pattern that the participants orient to and which serves as a procedure for dealing with, and generating an account for, one participant’s production of an inapposite action. As will be shown, the instantiation and progressive realization of this sequential procedure requires local inferential work from the participants. While some facets of this inferential work appear to be shaped by the particular context of the ongoing interaction, others are integral to the workings of the sequence as such. Moreover, the analyses suggest that participants’ understanding of oh that’s right as embodying an implicit memory claim rests on an inference which is based on a kind of semanticpragmatic compositionality. The paper thus illustrates how inferences in conversational interaction can be systematically studied and points to the merits of combining an interactional and a linguistic perspective.
Determination of uranium and thorium concentrations in thorium ore sample using artificial neural network and comparison with net area peak method
Authors: Islami rad Seyedeh Zahra , Peyvandi Reza Gholipour 
Published: May 2018

Abstract
In order to determine favorable and different elements in soil, the rapid and accurate methods are required. In this research, simultaneous prediction of thorium and uranium in soil samples was performed via gamma spectrometry. Then, the acquired data were analyzed with artificial neural network (ANN) and net area peak (NAP). Natural soil samples obtained from thorium ore consisting of thorium and uranium were used to train models (ANN and NAP). The techniques were evaluated with respect to prediction ability of uranium and thorium concentrations and robustness. Using proposed ANN and NAP methods, the thorium concentration was predicted with mean relative error percentage less than 8.27% and 9.30%, respectively. Also, uranium concentration just was determined with ANN because the NAP method cannot measure uranium concentration. The performance of the neural network model and NAP technique were compared with the acquired empirical data. The results showed that the neural network can more accurately predict the thorium and uranium concentrations in soil samples.
Adsorptive extraction of uranium (VI) from seawater using dihydroimidazole functionalized multiwalled carbon nanotubes
Authors: Tian Kun , Wu Jinling , Wang Jianlong 
Published: May 2018

Abstract
The adsorptive extraction of uranium (VI) was investigated using multiwalled carbon nanotubes functionalized with dihydroimidazole (DIM-MWCNTs). Dihydroimidazole was grafted onto the surface of MWCNTs via silane coupling agent, N-(3-triethoxysilylpropyl)-4,5-dihydroimidazole. The new adsorbent was characterized using Fourier transform infrared, scanning electron microscope and X-ray Photoelectron Spectroscopy. DIM-MWCNTs were compared with MWCNTs and amidoxime modified MWCNTs (AO-MWCNTs) for uranium adsorption under seawater conditions. The adsorption capacity of uranium onto DIM-MWCNTs was 54.9 mg g−1 at 298 K, which was about 4 times of MWCNTs and similar to that of AO-MWCNTs. Compared with AO-MWCNTs, DIM-MWCNTs were more suitable for seawater pH, and less affected by vanadium. Although DIM-MWCNTs were more affected by carbonate than AO-MWCNTs, DIM-MWCNTs maintained a higher adsorption capacity than AO-MWCNTs due to its alkali resistance. Pyridine-like nitrogen (CH=N–CH) contributed to the adsorption of uranium. The results suggested that DIM-MWCNTs were a potential effective adsorbent for the separation of uranium under seawater condition.

A multivariate regime-switching GARCH model with an application to global stock market and real estate equity returns
Authors: Haas Markus , Liu Ji-Chun 
Published: May 2018

Abstract
We consider a multivariate Markov-switching GARCH model which allows for regime-specific volatility dynamics, leverage effects, and correlation structures. Conditions for stationarity and expressions for the moments of the process are derived. A Lagrange Multiplier test against misspecification of the within-regime correlation dynamics is proposed, and a simple recursion for multi-step-ahead conditional covariance matrices is deduced. We use this methodology to model the dynamics of the joint distribution of global stock market and real estate equity returns. The empirical analysis highlights the importance of the conditional distribution in Markov-switching time series models. Specifications with Student’s t innovations dominate their Gaussian counterparts both in- and out-of-sample. The dominating specification appears to be a two-regime Student’s t process with correlations which are higher in the turbulent (high-volatility) regime.

Das frühste Amduat-Exemplar im Tal der Könige
Authors: Abdel Ghany Khaled 
Published: May 2018

Summary
After G. Daressy had indicated in the Catalogue général that two small mud-plaster fragments of Amduat (CG 24990 C) were found in the tomb of king Thutmosis I (KV 38), egyptologists assumed that the tomb KV 38 may have been originally decorated with a mud-plaster version of Amduat – however, there were neither archaeological evidences nor illustrations available. For this reason in 2015 I started an exploration in the tomb KV 38. In this search, I actually found further mud-plaster fragments of the Amduat book in the small side chamber (Ja). After examination and analysis of the discovered fragments with comparable scenes from the tomb of Thutmose III (KV 34) I think that the mud-plaster fragment scenes from the tomb of Thutmosis I (KV 38) are much earlier than the similar scenes from the tomb of Thutmosis III. Therefore, the discovered mud-plaster Amduat fragments from the tomb KV 38 represent the earliest ever Amduat specimen in the Valley of the Kings, made by the King Thutmosis I.
