Published: July 2018

Abstract
Theileria lestoquardi, T. ovis, and T. annulata are recognized as major causative agents for ovine and cattle theileriosis in Iran, respectively. Recently, there have been reports on the presence of Theileria spp. (Theileria sp. OT1, Theileria sp. OT3, and Theileria sp.). In this study, 37 blood samples were collected from sheep and cattle with clinically suspected Theileria infection in the Northwest of Iran. The samples were analyzed using a light microscope. DNA samples were amplified via nested-polymerase chain reaction (PCR) of 18S rRNA gene. The amplicons were digested with HpaII, following restriction fragment length polymorphism (RFLP) and sequenced to reconfirm Theileria species. The microscopic examination indicated that 4 out of 37 (10.8%) blood samples were infected with Theileria spp. Based on the nested PCR-RFLP and sequencing data, 5.4%, 13.5%, and 27% of blood samples were infected with Theileria sp. OT3, T. ovis, and T. annulata, respectively. The pairwise distance matrix of Theileria sp. OT3 showed 99.8–100% identity and 0–0.2% divergence in comparison with the registered sequences. The present study is the first report of Theileria sp. OT3 in Iran. To the evaluate evolution of Theileria spp. and providing resultant genetic data, further research with a larger sample is necessary in the region.

Authors: Kornacka Aleksandra , Cybulska Aleksandra , Moskwa Bożena 
Published: July 2018

AbstractToxoplasma gondii, a coccidian parasite known to infect almost all warm-blooded animals, is the cause of one of the most common zoonotic parasitic diseases. The aim of the study is to determine whether the 529 bp fragment or the TGR1E gene is more useful target for PCR identification ofT. gondii, for common use. The brains of 221 carnivores and omnivores collected between 2013 and 2015 from north-eastern Poland were examined for the presence of this parasite. The DNA was extracted and then amplified using specific primers. Positive results were obtained in 24% of brain samples using the TGR1E target and 19% using the 529 bp sequence. The results demonstrate that both TGR1E and 529 bp repeat element are suitable for detectingT. gondiiDNA in wildlife animals, and the combination of two methods is necessary to obtain reliable results.
Local Information, Income Segregation, and Geographic Mobility
Authors: Bond Timothy N. , Salisbury Laura 
Published: July 2018

Abstract
We develop a model of migration in the face of geographic information asymmetries. Firms from a given city observe whether or not a local worker is a member of a disadvantaged local community, a negative indicator of productivity, but do not have this information for migrants to this city. With this knowledge, workers must decide whether to migrate and obscure information about their community of origin. Our model generates results consistent with recent trends in intergenerational mobility and internal migration as well as new predictions about the relationship between migrant outcomes and income segregation. We confirm these predictions using data from the U.S. census.
A theoretical study of digital silicon photomultiplier utilization in diffuse optical imaging systems
Authors: Haddadifam Taha , Karami Mohammad Azim 
Published: July 2018

Abstract
Digital silicon photomultiplier (dSiPM) is introduced for diffuse optical imaging (DOI) applications instead of conventional photomultiplier tubes and avalanche photodiodes (APDs) as a state-of-the-art detector. According to the low-level light regime in DOI applications, high sensitivity and high dynamic range (DR) image sensors are needed for DOI systems. dSiPM is proposed as a developing detector which can detect low-level lights. Also, an accurate equation is obtained for calculating the DR of dSiPMs. Different dSiPMs and the corresponding benefits are studied for DOI applications. Furthermore, a 120 dB DR dSiPM is chosen for use in DOI systems. It is shown that dSiPMs can be utilized in DOI configurations such as time domain (TD), frequency domain (FD) and continuous wave (CW) systems. Ultimately, by utilizing dSiPM in DOI systems, the DOI method can be used for thoracic imaging due to the high DR and signal-to-noise ratio (SNR) of the detector.
An Adaptive Fuzzy Feedforward-Feedback Control System Applied to a Saccharification Process
Authors: Fonseca Rodolpho Rodrigues , Sencio Rafael Ribeiro , Franco Ivan Carlos , Da Silva Flávio Vasconcelos 
Published: July 2018

Abstract
In industrial bioprocess control, disturbance sources typically influences process variable regulation. These disturbances may reduce a system control performance or even affect the final bioproduct quality. Therefore, feedforward control is desired because it anticipates the effects caused by these disturbances in an attempt to keep the process variable at the setpoint value. However, designing a feedforward control law requires process modeling, which can be a tough task when dealing with bioprocesses that are intrinsically nonlinear and multivariable systems. Thus, an adaptive feedforward control law or other advanced control system is needed for satisfactory disturbance rejection. For this reason, a general fuzzy feedforward control system is proposed in this paper to replace the classical feedforward control, making it easier to implement the feedforward control action by avoiding nonlinear and multivariable process modeling. The adaptive fuzzy feedforward-feedback (A4FB) system was applied to a product concentration control loop in an enzymatic reactor, to reject disturbances caused by variations in the substrate and enzymatic solutions feed concentration. The results showed that the A4FB controller rejected much more disturbance effects than classical feedforward control law, demonstrating its advantage, supported by not only its simple implementation, but also its improved disturbance rejection.

Published: July 2018

Abstract
A new functional pH-responsive polyurethane-based nanomicelle has been developed with BES-Na as the functional monomer, the buffering agent with tertiary amine, and sulfonic acid group was incorporated into the hydrophilic shell as the functional agent, which resulted in polyurethane nanosystem with pH-sensitive property. Folic acid (FA) was chosen as model hydrophobic drug to evaluate the loading and pH-triggered release of the PU micelles in vitro drug loading and release. The drug loading content (LC) and the encapsulation efficiency (EE) for FA-loaded micelles in phosphate-buffered solutions were 7.68% and 27.72%, respectively, and the largest accumulative drug release percentages in pH 6.8 and pH 5.0 were 79.17% and 89.83% in 24 h, respectively. A facile and versatile approach has been provided for the design and fabrication of smart nanovehicles for effective drug delivery and opens a new thought in the design and fabrication of biodegradable polyurethanes for next generation of nanomicellar systems.
Innovation Culture in SMEs: The Importance of Organizational Culture, Organizational Learning and Market Orientation
Authors: Abdul-Halim Hasliza , Ahmad Noor Hazlina , Geare Alan , Thurasamy Ramayah 
Published: July 2018

AbstractAcademic and practitioner have considered innovation as an approach to produce value to customer in order to remain competitive in the market. However, previous studies on innovation culture among small and medium enterprises (SMEs) have received little attention and SMEs need to inculcate the innovation culture in order to generate innovation. Hence, the purpose of this paper is to investigate empirically the influence of organizational culture, organizational learning and market orientation on innovation culture. A questionnaire-based survey was conducted to gather data from SMEs in Malaysia. Questionnaires were distributed and gathered with a total of 183 usable responses. The analysis was conducted via SMART PLS to produce interesting findings. Findings suggest that all dimensions of organizational culture (adaptability, involvement, mission and consistency) have an influence on innovation culture, organizational learning in terms of information acquisition and behavioural & cognitive have an impact on innovation culture. Finally, only competitor orientation influences innovation culture. Although SMEs play an important role within the Malaysia economy, their contribution to innovation is small and marginal. This study makes an important contribution by providing information to SMEs on the elements that could nurture innovation culture in their organizations. As such, it is hoped that this study will generate interest among the researchers to reach more conclusive evidence about the practice of innovation culture among SMEs in Malaysia. More effort should be devoted to comprehending the concept of innovation culture among SMEs from the context of developing country. The findings combined with the suggestions may offer alternative insights on innovation culture and extend a basic framework for further investigation.
Idempotence of finitely generated commutative semifields
Authors: Kala Vítězslav , Korbelář Miroslav 
Published: July 2018

Abstract
We prove that a commutative parasemifield S is additively idempotent, provided that it is finitely generated as a semiring.
Consequently, every proper commutative semifield T that is finitely generated as a semiring is either additively constant or additively idempotent.
As part of the proof, we use the classification of finitely generated lattice-ordered groups to prove that a certain monoid associated to the parasemifield S has a distinguished geometrical property called prismality.
Dirichlet series of two variables, real analytic Jacobi–Eisenstein series of matrix index, and Katok–Sarnak type result
Authors: Mizuno Yoshinori 
Published: July 2018

Abstract
We study a real analytic Jacobi–Eisenstein series of matrix index and deduce several arithmetically interesting properties.
In particular, we prove the followings: (a) Its Fourier coefficients are proportional to the average values of the Eisenstein series on higher-dimensional hyperbolic space.
(b) The associated Dirichlet series of two variables coincides with those of Siegel, Shintani, Peter and Ueno.
This makes it possible to investigate the Dirichlet series by means of techniques from modular form.

Effects of moisture content and temperature on wood creep
Authors: Hsieh Tai-Yun , Chang Feng-Cheng 
Published: July 2018

Abstract
The effects of moisture content (MC) and temperature (T) on the creep of Japanese cedar were investigated via a series of short-term creep tests, while MC had a higher effect than T, desorption of water caused more deformation. The results were separated into two distinct groups with MCs higher or lower than the equilibrium moisture content (EMC) and it was found that the mechano-sorptive effect is time-independent. The total creep strain of wood was explained by a model considering the instantaneous strain, creep strain and strain induced by the mechano-sorptive effect. The proposed model is in agreement with the creep master curves based on the time-temperature superposition principle (tTSP).

Published: July 2018

Abstract
The Moringa oleifera leaf is an important source worldwide with a high nutritional value and functions in food and feed that may also treat a myriad of ailments but the leaf has low organoleptic properties and digestibility. To overcome this shortcoming, a novel Aspergillus niger was isolated from the Moringa leaf material. The fungal strain grows well on moist Moringa leaves and requires no additives. After performing a single factor test for temperature, moisture, inoculation size, and fermentation, the optimized condition was determined by using a response surface method, followed by a small-scale production test. The pleasant, sweet smelling aroma in the fermented leaves was then generated, supplementing than its native repulsive smell. The protein content and digestibility of the leaves increased by 23.4 % and 54.4 %, respectively; the direct-fed microbes reached up to 1.99 × 109 CFU per gram of fermented freeze-dried Moringa leaves. Digestive lignocellulolytic enzymes were substantially produced with 2.97 ± 0.24 U.g−1 of filter paper activity and 564.9 ± 37.4 U.g−1 of xylanase activity. Moreover, some functional components, such as flavonoids and γ-Aminobutyric acid content, were also significantly increased compared to that of the unfermented leaves. In conclusion, the feed quality and digestibility of Moringa oleifera leaves were greatly improved via solid-state fermentation by Aspergillus niger. Fermented Moringa oleifera can be used as a potentially high- quality feed alternative for the animal industry.

Authors: Sun XingLi 
Published: July 2018

Abstract
The Pseudo Random Noise (PRN) codes is an important part of the GNSS system based on Codes Division Multiple Access (CDMA), and it is the key to channel separation and satellite distinction. The GNSS system excellent performance characteristics of multiple access and spread spectrum are realized by the PRN codes. According to the officially released Interface Control Documents (ICDs), the Beidou global navigation satellite system (BDS-3) B1C and GPS L1C have chosen the Weil codes as PRN codes whose generation is based on the number theoretic method. The Weil codes has the advantages of flexible codes length, good performance and large candidate set, therefore, this paper mainly studies 63 pairs of data/pilot channel PRN codes for BDS-3 B1C and GPS L1C. On the basis of introducing BDS-3 B1C and GPS L1C PRN codes, mainly for the Weil codes generation principle, codes evaluation criteria and intra-system and inter-system odd/even auto-correlation and cross-correlation characteristics are simulated in detail. The experimental results show that the upper limit value, lower limit value, the mean and standard deviation of the odd auto-correlation and cross-correlation of the PRN codes of the BDS-3 B1C signal were better than those of the GPS L1C PRN codes. The performance of odd and even cross-correlation are almost similar between BDS-3 B1C and GPS L1C signal inter-systems, which are slightly worse than the intra-system, and the upper limit value of the inter-system is lower than 2.94 dB in the GPS L1C intra-system.
Tail Risk in a Retail Payments System
Authors: Sabetti Leonard , Jacho-Chávez David T. , Petrunia Robert , Voia Marcel C. 
Published: July 2018

AbstractIn this paper, we study a credit risk (collateral) management scheme for the Canadian retail payment system designed to cover the exposure of a defaulting member. We estimate ex ante the size of a collateral pool large enough to cover exposure for a historical worst-case default scenario. The parameters of the distribution of the maxima are estimated using two main statistical approaches based on extreme value models: Block-Maxima for different window lengths (daily, weekly and monthly) and Peak-over-Threshold. Our statistical model implies that the largest daily net debit position across participants exceeds roughly $1.5 billion once a year. Despite relying on extreme-value theory, the out of sample forecasts may still underestimate an actual exposure given the absence of observed data on defaults and financial stress in Canada. Our results are informative for optimal collateral management and system design of pre-funded retail-payment schemes.

MRHS solver based on linear algebra and exhaustive search
Authors: Raddum Håvard , Zajac Pavol 
Published: July 2018

Abstract
We show how to build a binary matrix from the MRHS representation of a symmetric-key cipher. The matrix contains the cipher represented as an equation system and can be used to assess a cipher’s resistance against algebraic attacks. We give an algorithm for solving the system and compute its complexity. The complexity is normally close to exhaustive search on the variables representing the user-selected key. Finally, we show that for some variants of LowMC, the joined MRHS matrix representation can be used to speed up regular encryption in addition to exhaustive key search.

Published: July 2018

Abstract

Background
The overall incidence of hyperphenylalaninemia (HPA) in China is 1:11,763, with tetrahydrobiopterin (BH4) deficiency accounting for 8.55% of patients with HPA in the mainland. Much progress has been made in the diagnosis and treatment of BH4 deficiency with the introduction of neonatal screening in China. However, the screening rate is still low and screening is not universally available.

Methods
A total of 44 BH4-deficient patients were enrolled in this study, of which 39 were diagnosed with BH4 deficiency, while the remaining five showed typical characteristics of BH4 deficiency at a later period. The entire coding regions and adjacent intronic regions of GCH1, PTS, PCBD1 and QDPR genes were analyzed using target sequencing.

Results
Nineteen (n=19) different mutations in the PTS gene including four novel mutations and one mutation in QDPR were identified. p.P87S, p.D96N, IVS1-291A>G, p.N52S, p.K91R, p.V56M, p.T106M and p.F40GfsX53 in PTS were the prevalent mutations with ≥3% relative frequency. The mutation p.R221X in the QDPR gene was found with relatively lower frequencies (2.27%). The remaining 12 mutations in PTS were found at relative frequencies of 1.14%.

Conclusions
The results could be of value for genetic counseling and prenatal diagnosis in the patients’ families and for the molecular diagnosis of BH4 deficiencies. Furthermore, four novel mutations expand and improve the PTS mutation database.
Relationship between intercellular adhesion molecule-1 and morbidly adherent placenta
Authors: Korkmazer Engin , Nizam Rampia , Arslan Emine , Akkurt Özgür 
Published: July 2018

Abstract

Objective
Morbidly adherent placenta (MAP) is a clinical condition the prevalance of which is steadily increasing. It is described as the invasion of the placenta into the uterine wall through the myometrium and beyond. Several studies have shown that intercellular adhesion molecule-1 (ICAM-1) increases the invasion capability of tumor cells and placental cells. In our study, we investigated the expression of ICAM-1 in MAP cases.

Methods
This is a prospective case-control study. Eighty-nine patients who were diagnosed with MAP and 96 patients, without adherent placenta, as a control group were included in the study. ICAM-1 staining was examined by immuno-histochemical staining in placental samples.

Results
Of the 89 patients in the MAP group, 72 (80.8%) showed positive staining, while 26 (27%) did so in the control group. ICAM-1 positive staining in the MAP group was statistically significantly higher (P=0.03).

Conclusion
This is the first study investigating the relationship between MAP and ICAM-1 in the literature. In our study, we showed that ICAM-1 expression increased in the MAP group.

The aim of this paper is to obtain the boundedness of this function inLp,α,p> 1. Firstly, we provedL2,α-boundedness by means of the Bessel-Plancherel theorem. Then, its weak-type (1, 1) andLp,α,p> 1 boundedness are proved by taking into account vector-valued functions.
