Authors: Qiu Yuanying , Qiu Xun , Guo Xianghu , Wang Dian , Sun Lijie
Published: April 2017

In order to effectively reduce the thermal stresses of Si/GaAs bonding wafers during their annealing process, first of all, based on E. Suhir’s bimaterial thermal stress theory, the thermal stresses in the wafer bonding interfaces are analyzed and the thermal stress distribution formulas are obtained. Then, the thermal stress distribution curves of Si/GaAs bonding interfaces are investigated by finite element method (FEM) and are compared with the results from E. Suhir’s bimaterial thermal stress theory. Finally, some effective strategies are proposed to reduce the thermal stresses in the bonding interfaces.

Authors: Hu Qinrui , Bai Yujing , Chen Xiaoli , Huang Lvzhen , Chen Yi , Li Xiaoxin
Published: April 2017

Objective. To determine the prevalence and risk factors for the recurrence of retinopathy of prematurity (ROP) in Zone II Stage 3+ after ranibizumab treatment.Methods. This was a retrospective, nonrandomized, noncontrolled study that excluded Zone I and aggressive posterior ROP (APROP) cases. Infants who developed Zone II Stage 3 ROP with plus disease and underwent initial intravitreal injection of ranibizumab (IVR) were recruited. Patients were divided into 2 groups based on the outcome after initial ranibizumab treatment: recurrence of ROP or favorable outcome. Data was collected and analyzed by SPSS 16.0.Results. Forty-two patients were included, and 80 eyes with Zone II Stage 3+ were subjected to IVR treatment. Eleven of 42 patients (26.2%, 18 eyes) had a recurrence of ROP after the initial treatment. On univariate analysis, preretinal hemorrhage before treatment was significantly different between the two groups (P=0.000). Multivariate analysis found that preretinal hemorrhage before treatment was the only factor associated with the recurrence of ROP in our study (P=0.004).Conclusions. The recurrence rate of ROP in Zone II Stage 3+ after initial ranibizumab treatment was notable and preretinal hemorrhage before treatment was associated with the recurrence of ROP in our study.

Published: April 2017

Purpose. The aim of this present study was to investigate the ground reaction forces (GRFs) alterations in stroke survivors with diabetic peripheral neuropathy (DPN).Methods. Ten stroke survivors with DPN, 10 stroke survivors without DPN, and 10 healthy controls with matched body weight between groups participated in this case-control cross-sectional study. Three-dimensional GRFs (anterior-posterior, medial-lateral, and vertical) were collected at a comfortable walking speed using the Nexus Vicon motion analysis system and force plate. The Kruskal–Wallis test was used to analyze GRFs parameters.Results. We found significant alterations of medial-lateral forces of the nonparetic side and vertical forces of the paretic side in stroke survivors with DPN compared to stroke survivors without DPN and healthy controls. In addition, there were smaller braking and lower propulsion peak in anterior-posterior forces, smaller magnitude of medial-lateral forces, and lower first and second peak of vertical forces in stroke survivors with DPN compared to stroke survivors without DPN and healthy controls.Conclusion. The study findings identified that GRFs were affected in stroke survivors with DPN on both the paretic and the nonparetic sides. Further investigations are warranted to explore the impact of DPN on the kinematics and muscle activity related to the gait performance in stroke survivors with DPN.
Adipokine Contribution to the Pathogenesis of Osteoarthritis
Authors: Azamar-Llamas Daniel , Hernández-Molina Gabriela , Ramos-Ávalos Bárbara , Furuzawa-Carballeda Janette
Published: April 2017

Recent studies have shown that overweight and obesity play an important role in the development of osteoarthritis (OA). However, joint overload is not the only risk factor in this disease. For instance, the presence of OA in non-weight-bearing joints such as the hand suggests that metabolic factors may also contribute to its pathogenesis. Recently, white adipose tissue (WAT) has been recognized not only as an energy reservoir but also as an important secretory organ of adipokines. In this regard, adipokines have been closely associated with obesity and also play an important role in bone and cartilage homeostasis. Furthermore, drugs such as rosuvastatin or rosiglitazone have demonstrated chondroprotective and anti-inflammatory effects in cartilage explants from patients with OA. Thus, it seems that adipokines are important factors linking obesity, adiposity, and inflammation in OA. In this review, we are focused on establishing the physiological mechanisms of adipokines on cartilage homeostasis and evaluating their role in the pathophysiology of OA based on evidence derived from experimental research as well as from clinical-epidemiological studies.

Published: April 2017

Aluminium phosphide (ALP) is widely used as a fumigant pesticide. In case of ALP poisoning, it is responsible for myocardial dysfunction, related to toxic myocarditis, and hemodynamic disorders. We report a case of a 28-year-old female who had intentionally ingested ALP and was admitted with cardiogenic shock. The transthoracic echocardiography (TTE) at the time of admission showed severe global myocardial hypokinesia with the presence of a giant left ventricular thrombus. Cardiovascular magnetic resonance (CMR) revealed extensive toxic myocarditis with a left ventricular systolic dysfunction. All cardiac lesions were reversible after symptomatic treatment, within 6 months. We aim, by reporting this case, to evidence the complete reversibility of cardiac injury due to aluminium phosphide poisoning documented by transthoracic echocardiography and cardiovascular magnetic resonance.

Published: April 2017

Pelvic tuberculosis is a type of extrapulmonary tuberculosis. The disease is accompanied by clinical and laboratory findings which may be unspecific and present aspects of other diseases, including gynecological malignancies. In this report, the authors presented a case of pelvic tuberculosis associated with peritoneal tuberculosis in a young woman exhibiting imaging and tumor markers consistent with ovarian neoplasm. An intraoperative frozen section analysis detected atypical cells that were suggestive of ovarian borderline or malignant epithelial neoplasia. The pathological analysis showed granulomatous inflammation in the right ovary and fallopian tube with a pattern of mycobacteriosis that was consistent with the presence of mycobacteria morphologically compatible with Mycobacterium tuberculosis. The patient had a complete remission after the use of antituberculosis drugs.

Published: April 2017

This study was performed to make comparative analysis of the clinical findings between the two different types of the implant-assisted removable partial dentures: removable partial dentures using implant surveyed bridge as an abutment (ISBRPD) and overdenture type of removable partial denture using implant attachment (IARPD). Implant cumulative survival rate, marginal bone resorption, probing depth, peri-implant inflammation, bleeding, plaque, calculus, and complications were evaluated on 24 patients who were treated with implants in conjunction with removable partial denture and have used them for at least 1 year (ISCRPD: n=12; IARPD: n=12). There was no failed implant and all implants were functioning without clinical mobility. Marginal bone loss of ISCRPD (1.44 ± 0.57 mm) was significantly lower than that of IARPD (p<0.05). There was no significant difference in probing depth, peri-implant inflammation, bleeding, and plaque between the two groups (p>0.05), while the calculus was significantly more observed in ISCRPD group than in IARPD group (p<0.05). The retention loss of IARPD was the most common complication. Within the limits of the present study, it was found that well-planned ISBRPD was clinically appropriate. Longitudinal and systematic clinical studies are necessary to confirm these results.
Understanding the Role of Chemokines and Cytokines in Experimental Models of Herpes Simplex Keratitis
Authors: Azher Tayaba N. , Yin Xiao-Tang , Stuart Patrick M.
Published: April 2017

Herpes simplex keratitis is a disease of the cornea caused by HSV-1. It is a leading cause of corneal blindness in the world. Underlying molecular mechanism is still unknown, but experimental models have helped give a better understanding of the underlying molecular pathology. Cytokines and chemokines are small proteins released by cells that play an important proinflammatory or anti-inflammatory role in modulating the disease process. Cytokines such as IL-17, IL-6, IL-1α, and IFN-γand chemokines such as MIP-2, MCP-1, MIP-1α, and MIP-1βhave proinflammatory role in the destruction caused by HSV including neutrophil infiltration and corneal inflammation, and other chemokines and cytokines such as IL-10 and CCL3 can have a protective role. Most of the damage results from neutrophil infiltration and neovascularization. While many more studies are needed to better understand the role of these molecules in both experimental models and human corneas, current studies indicate that these molecules hold potential to be targets of future therapy.
Higher-Order Chromatin Regulation of Inflammatory Gene Expression
Authors: Xu Jin-Wen , Ling Shuang , Liu Jun
Published: April 2017

Whether it is caused by viruses and bacteria infection, or low-grade chronic inflammation of atherosclerosis and cellular senescence, the transcription factor (TF) NF-κB plays a central role in the inducible expression of inflammatory genes. Accumulated evidence has indicated that the chromatin environment is the main determinant of TF binding in gene expression regulation, including the stimulus-responsive NF-κB. Dynamic changes in intra- and interchromosomes are the key regulatory mechanisms promoting the binding of TFs. When an inflammatory process is triggered, NF-κB binds to enhancers or superenhancers, triggering the transcription of enhancer RNA (eRNA), driving the chromatin of the NF-κB-binding gene locus to construct transcriptional factories, and forming intra- or interchromosomal contacts. These processes reveal a mechanism in which intrachromosomal contacts appear to be cis-control enhancer-promoter communications, whereas interchromosomal regulatory elements construct trans-form relationships with genes on other chromosomes. This article will review emerging evidence on the genome organization hierarchy underlying the inflammatory response.
Optimization Model for Multi‐Vehicle‐Type Structure in Urban Bus Systems
Authors: Zhao Shuzhi , Wang Dong , Sun Jian , Liu Huasheng
Published: April 2017

Nowadays, bus lines commonly share terminals, especially in urban areas, because an independent operation of each line would cause a large waste of resources. In addition, if lines share terminal all lines can be monitored by unified management, while the vehicles of different sizes can complement each other. Although the dispatcher generally sets up fixed departure intervals for bus lines, there are differences between bus lines in terms of operating time distribution and line volume. Thus, a new optimization model for multi‐vehicle‐type structure in urban bus system is proposed in this paper. The optimization was conducted according to two main characteristics of bus systems, bus company expense and bus service quality. The optimization model was designed based on minimal possible expense and maximal possible quality. At the same time, we proposed a Markov method based on alternative relations to solve the model. The proposed model was verified by real urban bus system. Moreover, the simulations in MATLAB software environment have proven a high efficiency and applicability of the proposed method.
ARM-Cortex M3-Based Two-Wheel Robot for Assessing Grid Cell Model of Medial Entorhinal Cortex: Progress towards Building Robots with Biologically Inspired Navigation-Cognitive Maps
Authors: Cuneo J. , Barboni L. , Blanco N. , del Castillo M. , Quagliotti J.
Published: April 2017

This article presents the implementation and use of a two-wheel autonomous robot and its effectiveness as a tool for studying the recently discovered use of grid cells as part of mammalian’s brains space-mapping circuitry (specifically the medial entorhinal cortex). A proposed discrete-time algorithm that emulates the medial entorhinal cortex is programed into the robot. The robot freely explores a limited laboratory area in the manner of a rat or mouse and reports information to a PC, thus enabling research without the use of live individuals. Position coordinate neural maps are achieved as mathematically predicted although for a reduced number of implemented neurons (i.e., 200 neurons). However, this type of computational embedded system (robot’s microcontroller) is found to be insufficient for simulating huge numbers of neurons in real time (as in the medial entorhinal cortex). It is considered that the results of this work provide an insight into achieving an enhanced embedded systems design for emulating and understanding mathematical neural network models to be used as biologically inspired navigation system for robots.
The Effect of Corneal Refractive Surgery on Glaucoma
Authors: Kozobolis Vassilios , Konstantinidis Aristeidis , Sideroudi Haris , Labiris G.
Published: April 2017

Laser-assisted refractive procedures have become very popular in the last two decades. As a result, a “generation” of patients with altered corneal properties is emerging. These patients will require both cataract extraction and glaucoma follow-up in the future. Since the glaucoma examination largely depends on the corneal properties, the reshaped postrefractive surgery cornea poses a challenge in the diagnosis, follow-up, and management of the glaucomatous patient. In order to overcome this problem, every patient who is planned to undergo corneal refractive surgery must have a thorough glaucoma examination in order for the ophthalmologist to be able to monitor their patients for possible glaucoma development and/or progression. Some examinations such as tonometry are largely affected by the corneal properties, while others such as the evaluation of the structures of the posterior pole remain unaffected. However, the new imaging modalities of the anterior segment in combination with the most recent advances in tonometry can accurately assess the risk for glaucoma and the need for treatment.

Published: April 2017

Antianemic medicament ferrous gluconate, ferrous fumarate, and a Dynabi tablet with a basic iron bearing ingredient were studied with the use of Mössbauer spectroscopy. Room temperature spectra of ferrous gluconate gave clear evidence that the two phases of iron were present: ferrous (Fe2+) as a major one with a contribution at and above 91 a.u.% and ferric (Fe3+) whose contribution was found to be ~9 a.u.%. In the case of ferrous fumarate, a single phase was measured corresponding to ferrous (Fe2+) state. A Dynabi tablet consists of ferrous fumarate and ferrous fumarate. The ferric phase in ferrous gluconate is able to be reached about ~3.6 a.u.% in a tablet.
Fast Compressed Sensing MRI Based on Complex Double-Density Dual-Tree Discrete Wavelet Transform
Authors: Chen Shanshan , Qiu Bensheng , Zhao Feng , Li Chao , Du Hongwei
Published: April 2017

Compressed sensing (CS) has been applied to accelerate magnetic resonance imaging (MRI) for many years. Due to the lack of translation invariance of the wavelet basis, undersampled MRI reconstruction based on discrete wavelet transform may result in serious artifacts. In this paper, we propose a CS-based reconstruction scheme, which combines complex double-density dual-tree discrete wavelet transform (CDDDT-DWT) with fast iterative shrinkage/soft thresholding algorithm (FISTA) to efficiently reduce such visual artifacts. The CDDDT-DWT has the characteristics of shift invariance, high degree, and a good directional selectivity. In addition, FISTA has an excellent convergence rate, and the design of FISTA is simple. Compared with conventional CS-based reconstruction methods, the experimental results demonstrate that this novel approach achieves higher peak signal-to-noise ratio (PSNR), larger signal-to-noise ratio (SNR), better structural similarity index (SSIM), and lower relative error.

According to the mobile storage characteristic of electric vehicles, an emergency power supply model about the electric vehicles is presented through analyzing its storage characteristic. The model can ensure important consumer loss minimization during power failure or emergency and can make electric vehicles cost minimization about running, scheduling, and vindicating. In view of the random dispersion feature in one area, an emergency power supply scheme using the electric vehicles is designed based on the K‐means algorithm. The purpose is to improve the electric vehicles initiative gathering ability and reduce the electric vehicles gathering time. The study can reduce the number of other emergency power supply equipment and improve the urban electricity reliability.

From Big Brother to Al Maleka: The growing pains of TV format trade in the Arab region
Authors: Khalil Joe F.
Published: April 2017

Broadly defined as the sale of television programmes’ production rights and technologies, the TV format trade is a growing global business. Not only are formats representative of a wide array of programming practices but the process of licensing, casting, producing and ‘using’ these shows has become increasingly developed and sophisticated. This article underscores the coexistence between global TV formats and their locally/regionally originating Arab counterparts. It offers a brief overview of the multiple and localized meanings of formats and an abridged history of formats in the Arab region to reveal three distinct TV format stages: foundation, development and maturity. This article looks for answers to what is driving the maturity of format TV in the Arab region, not by looking at specific programmes but by examining the history, structure and production arrangements of media industries. Using a critical political economy approach, this article is the outcome of production ethnographies conducted in Beirut and Dubai.
Formats, cultural security and China’s going out policy
Authors: Keane Michael , Zhang Joy Danjing
Published: April 2017

This article investigates the relationship between television formats, cultural security and China’s ‘going out’ policy. Cultural security is a term used within Chinese policy circles to advocate the strengthening of media and cultural pursuits with a view to making them effective instruments of national ‘soft power’, a term coined by Joseph Nye (1990). Whereas ‘going out’ refers to Chinese business expansion internationally, in this article it describes media and cultural industries. We argue that these three elements constitute a new soft power coalition. Building on the existing demand, particularly among diasporic communities for historical dramas, formatting of talent and reality shows allow Chinese cultural identity to be reformed, remade, re-presented and modernized. The article provides background to the emergence of television formats, showing which kinds of programming passes both government scrutiny and the audience test. In the final section it looks at three examples of music talent shows, The Voice of China, I am a Singer, and Sing My Song that effectively function to reconnect domestic and diasporic audiences.
Can a GVC-oriented policy mitigate the inequalities of the world media system? Strategies for economic upgrading in the TV format global value chain
Authors: Chalaby Jean K.
Published: April 2017

The TV format business has evolved rapidly since the formation of a global format trading system at the millennium, with one notable exception: the UK remains the world’s leading exporter. Considering the UK was once a net importer of (US) TV formats, it is a remarkable turn of fortune that poses two questions: what lies behind it and can the recipe be applied elsewhere? This article argues that British broadcasting regulation helped build a local TV production sector that excels at export, and that it contains the core elements of a global value chain (GVC)-oriented policy. Comparing UK initiatives with other nations and regions (the Middle East, Israel and South Africa) demonstrates the benefits of the British regulatory framework. Using the TV format trade as a case study, this article acknowledges that the world media system may be unequal but, contra to the cultural imperialism thesis and critical political economy theory, it argues that developing countries can take measures to scale their creative industries and, in particular, encourage local TV producers to participate more actively in the TV content GVC. Strategies for economic upgrading, this article concludes, must use IP laws to incentivize creativity, must not restrict international trade, and need to take into account the global nature of the TV content value chain to help local firms position themselves accordingly.
The social networks and paradoxes of the opt-out movement amid the Common Core State Standards implementation: The case of New York
Authors: Wang Yinying
Published: April 2017

Opting out of state standardized tests has recently become a movement—a series of grassroots, organized efforts to refuse to take high-stakes state standardized tests. In particular, the opt-out rates in the state of New York reached 20% in 2015 and 21% in 2016. This study aims to illustrate the social networks and examine the paradoxes that have propelled the opt-out movement in New York—the movement’s epicenter with the highest opt-out rate in the United States. Drawing on the conceptual frameworks of social movement theory, social network theory, and policy paradox, this study compiled the opt-out corpus by using the data from 221 press-coverage and 30 archival documents. Social network analysis was performed by examining the relational data that suggest coalition ties between movement actors. Further, to explicate how the movement actors forged coalition ties, all data in the corpus were then coded by Stone’s framework of policy paradox regarding how the movement goals were articulated, how the movement was framed, and what policy solutions were mobilized. In addition to identifying the movement actors and two competing coalitions, it is found that to forge coalition ties, the movement actors in the opposing coalitions articulated contested goals of standardized testing, framed the movement via symbols, numbers, and interests, as well as mobilized policy solutions via inducements, rights, and power. The findings have important and timely implications for policymakers and movement actors as they seek and advance on common ground to make substantive changes in education policy.
Is the Common Core racing America to the top? Tracking changes in state standards, school practices, and student achievement
Authors: Lee Jaekyung , Wu Yin
Published: April 2017

This study examines the trends of the U.S. states’ reading and math proficiency standards before and after the adoption of the Common Core State Standards (CCSS) and explores their impact on school practices and student achievement. Drawing on the 2003-15 National Assessment of Educational Progress (NAEP) grades 4 and 8 assessment and survey datasets, the study gives new insights into the CCSS policy challenges and outcomes. The states that adopted CCSS raised the rigor of proficiency standards for their student assessments, reversing ‘race to the bottom’ trend during the earlier period of the No Child Left Behind Act (NCLB). However, the CCSS states failed to improve schools’ alignment of ELA and math programs with state/district assessments and also failed to improve students’ reading and math achievement more than the non-CCSS counterparts. The Common Core has helped America race to the top for performance standards, but not for performance outcomes yet.

Authors: Akar Filiz
Published: April 2017

The aim of this study is to determine the purposes and characteristics of adolescents' internet use. Furthermore, the study compared adolescents' internet use purposes in terms of gender, school type and grade level variables. The study group consisted of 1002 students who were studying in 10 public high schools in 2012-2013 academic year in İstanbul. The data were collected through the Internet Use Purposes Scale (IPUS) and were analyzed using descriptive statistics, t-test and ANOVA. Research revealed that duration of internet use of adolescents' increased over years. Also, more than half of the adolescents access internet at home, in the evening and at night. Girls use mobile phone two times more than boys in order to access internet. One out of every ten adolescents were found to be at risk of internet addiction. Results indicate that adolescents use internet mostly for the communication and learning purposes whereas they use the internet for the purposes of education, psychological needs and entertainment at lower levels. Significant differences were observed in terms of gender and school types. However, grade level did not have a significant effect on the purposes of adolescents' internet use.

Interpreting experiences of students using educational online technologies to interact with teachers in blended tertiary environments: A phenomenological study
Authors: Tuapawa Kimberley
Published: April 2017

Although educational online technologies (EOTs) have transformed the delivery of learning in higher education, significant EOT challenges have impeded their effectiveness, preventing widespread implementation. The persistence of these challenges suggests that tertiary education institutes (TEIs) have experienced a gap in understandings about the reality of key stakeholders’ EOT needs. This research made a phenomenological interpretation of key stakeholders’ EOT experiences, to establish their current EOT needs and challenges and provide a basis from which to recommend methods for effective EOT support. It analysed the EOT experiences of 10 students and 10 teachers from New Zealand and Australia and interpreted the meanings of the phenomena through an abstraction and articulation of local and global themes. This paper is the first in a series of six publications that presents the local themes. It documents the interpretations of students’ experiences with teachers, in reference to their use of four types of EOTs: online conference tools, learning management systems, blog sites and lecture capture tools. These interpretations, which include descriptions of stakeholders’ EOT challenges, helped to inform a set of recommendations for effective EOT use, to assist TEIs in their efforts to address EOT challenges and meet stakeholders’ needs.

Published: April 2017

Background:

Thyroid disorders are common during pregnancy. To date, a limited number of studies have reported differences in serum thyroid hormone concentrations between different ethnic groups. We sought to establish gestational age-specific reference intervals for serum levels of thyroid hormones in a multi-ethnic population and investigate whether separate reference intervals should be used for different ethnic groups.

Methods:

A total of 926 pregnant women from multiple ethnic groups attended four separate study visits spanning the three trimesters. Venous blood samples were taken at 9 to 14 weeks, 18 to 22 weeks, 28 to 32 weeks, and 34 to 39 weeks of gestation. Serum concentrations of thyroid-stimulating hormone (TSH), free thyroxine (T4), free triiodothyronine (T3), total T4, total T3, thyroid peroxidase antibody and thyroglobulin antibody were measured using Abbott Architect immunoassays. A total of 562 women with singleton pregnancies were found to be negative for both thyroid autoantibodies at all four study visits and thus included in the reference sample group for the establishment of reference intervals (2.5th to 97.5th percentiles).

Results:

Reference intervals for serum thyroid hormones at 9–14 weeks of gestation derived from the combined group of pregnant women are as follows: TSH, 0.01–2.39 mIU/L; free T4, 11.4–19.5 pmol/L; free T3, 4.23–6.69 pmol/L; total T4, 77.8–182.4 nmol/L; total T3, 1.39–2.97 nmol/L. No differences in the five thyroid parameters’ reference intervals are detectable among the ethnic groups except that at study visit 3 (28–32 weeks of gestation), the upper reference limit of total T3 in Malays (3.20 nmol/L; 90% CI, 2.99–3.76 nmol/L) is slightly higher than that in Chinese (2.86 nmol/L; 90% CI, 2.70–2.98 nmol/L).

Conclusions:

The findings from this study on a multi-ethnic cohort highlight the importance of establishing locally derived and gestational age-specific reference intervals for the five thyroid hormone parameters.
Crepant resolutions and open strings
Authors: Brini Andrea , Cavalieri Renzo , Ross Dustin
Published: April 2017

In the present paper, we formulate a Crepant Resolution Correspondence for open Gromov–Witten
invariants (OCRC) of toric Lagrangian branes inside Calabi–Yau 3-orbifolds by encoding the open theories
into sections of Givental’s symplectic vector space. The
correspondence can be phrased as the identification of these sections via a linear morphism of
Givental spaces. We deduce from this a
Bryan–Graber-type statement for disk invariants, which we extend
to arbitrary topologies in the Hard Lefschetz case. Motivated by
ideas of Iritani, Coates–Corti–Iritani–Tseng and Ruan, we furthermore propose (1) a general form
of the morphism entering the OCRC, which arises from a geometric
correspondence between equivariant K-groups, and (2) an all-genus
version of the OCRC
for Hard Lefschetz targets. We provide a complete proof of both statements in
the case of minimal resolutions of threefold

Bio-based chitosan/PVdF-HFP polymer-blend for quasi-solid state electrolyte dye-sensitized solar cells
Authors: Yahya Wan Zaireen Nisa , Meng Wong Theen , Khatani Mehboob , Samsudin Adel Eskandar , Mohamed Norani Muti
Published: April 2017

Dye-sensitized solar cells (DSSCs) have emerged to become one of the most promising alternatives to conventional solar cells. However, long-term stability and light-to-energy conversion efficiency of the electrolyte in DSSCs are the main challenges in the commercial use of DSSCs. Current liquid electrolytes in DSSCs allow achieving high power conversion efficiency, but they still suffer from many disadvantages such as solvent leakage, corrosion and high volatility. Quasi-solid state electrolytes have therefore been developed in order to curb these problems. A novel polymer electrolyte composed of biobased polymer chitosan, poly(vinylidene fluoride-hexafluoropropylene) (PVdF-HFP), 1-methyl-3-propylimidazolium iodide ionic liquid and iodide/tri-iodide redox salts in various compositions is proposed in this study as a quasi-solid state electrolyte. Fourier transform infrared microscopy (FTIR) studies on the polymer electrolyte have shown interactions between the redox salt and the polymer blend. The quasi-solid state electrolyte tested in DSSCs with an optimised weight ratio of PVdF-HFP:chitosan (6:1) with ionic liquid electrolyte PMII/KI/I2 has shown the highest power conversion efficiencies of 1.23% with ionic conductivity of 5.367×10−4 S·cm−1 demonstrating the potential of using sustainable bio-based chitosan polymers in DSSCs applications.

Published: April 2017

Suppose that B is a Brauer p-block of a finite group G with a unique
modular character φ. We prove that φ is liftable to an ordinary
character of G (which moreover is p-rational for odd p). This confirms
the basic set conjecture for these blocks.

On small profinite groups
Authors: Helbig Patrick
Published: April 2017

A profinite group is called small if it has only finitely many open subgroups of index n for each positive integer n. We show that every Frattini cover of a small profinite group is small. A profinite group is called strongly complete if every subgroup of finite index is open. We show that two profinite groups that are elementarily equivalent, in the first-order language of groups, are isomorphic if one of them is strongly complete, extending a result of Moshe Jarden and Alexander Lubotzky which treats the case of finitely generated profinite groups.
Computing with bivariate COM-Poisson model under different copulas
Authors: Mamode Khan Naushad , Rumjaun Wasseem , Sunecher Yuvraj , Jowaheer Vandna
Published: April 2017

Bivariate counts are collected in many sectors of research but the analysis of such data is often challenging because each series of counts may exhibit different levels and types of dispersion.
This paper addresses this problem by proposing a flexible bivariate COM-Poisson model that may handle any combination of over-, equi- and under-dispersion at any levels. In this paper, the bivariate COM-Poisson is developed via Archimedean copulas.
The Generalized Quasi-Likelihood (GQL) approach is used to estimate the unknown mean parameters in the copula-based bivariate COM-Poisson model while the dependence parameter is estimated using the copula likelihood. We further introduce a Monte Carlo experiment to generate bivariate COM-Poisson data under different dispersion levels. The performance of the GQL approach is assessed on the simulated data. The model is applied to analyze real-life epileptic seizures data.

Flatland plasmonics and nanophotonics based on graphene and beyond
Authors: Chen Pai-Yen , Argyropoulos Christos , Farhat Mohamed , Gomez-Diaz J. Sebastian
Published: April 2017

In this paper, we review and discuss how the recently discovered two-dimensional (2D) Dirac materials, particularly graphene, may be utilized as new efficient platforms for excitations of propagating and localized surface plasmon polaritons (SPPs) in the terahertz (THz) and mid-infrared (MIR) regions. The surface plasmon modes supported by the metallic 2D materials exhibit tunable plasmon resonances that are essential, yet missing, ingredients needed for THz and MIR photonic and optoelectronic devices. We describe how the atomically thin graphene monolayer and metamaterial structures based on it may tailor and control the spectral, spatial, and temporal properties of electromagnetic radiation. In the same frequency range, the newly unveiled nonlocal, nonlinear, and nonequilibrium electrodynamics in graphene show a variety of nonlinear and amplifying electromagnetic responses, whose potential applications are yet unexplored. With these 2D material platforms, virtually all plasmonic, optoelectronic, and nonlinear functions found in near-infrared (NIR) and visible devices can be analogously transferred to the long-wavelength regime, even with enhanced tunability and new functionalities. The spectral range from THz to MIR is particularly compelling because of the many spectral fingerprints of key chemical, gas, and biological agents, as well as a myriad of remote sensing, imaging, communication, and security applications.

Efect of Gamma 60Co Irradiation on The Growth, Lipid Content and Fatty Acid Composition of Botryococcus sp. Microalgae
Authors: Ermavitalini Dini , Yuliansari Niki , Prasetyo Endry Nugroho , Saputro Triono Bagus
Published: April 2017

Botryococcus sp. is one of microalgae species that has a high lipid content as much as 75% of their dry weight. But, lipid production by microalgae is regulated by their environmental condition (pH, light, temperature, nutrition, etc). Mutagenesis induced by Gamma 60Co irradiation can be utilized to alter the Botryococcus sp. genetic to get microalgae mutant strain that can produce a higher lipid content than the wild strain. Botryococcus sp. was irradiated with different doses of gamma ray of 60Co  (0, 2, 4, 6, and 10 Gy),  and the effect  on the growth, lipid content, and fatty acid composition of microalgae were observed. Research design used is random complete (RAL) with 95 %  confident level for quantitive analysis based on the biomass and lipid contents. More over fatty acid composition was analyzed by Gas Cromatography-Mass Spectrometry (GC-MS). Results showed that Gamma irradiated gave an effect on growth and lipid content of Botryococcus sp. But between the control treatment (0 Gy) with microalgae irradiated dose of 2 Gy, 4 Gy and 6 Gy were not significantly different. Whereas between the control with 10 Gy irradiated was significantly different. The highest biomassa and lipid content are found in 10 Gy irradiated microalgae with 0.833 gram biomass and 41% lipid content. Fatty acid profile of Botryococcus sp. control has 6 fatty acids while 10 Gy irradiated microalgae has 12 fatty acids, with the long-chain fatty acids increased, whereas short-chain fatty acids decreased.
