Broadband and tunable one dimensional strongly nonlinear acoustic metamaterials: Theoretical study.
Venue: Physical review. E

This paper focuses on the dispersion properties and mechanism of the one dimensional strongly nonlinear acoustic metamaterials (NAMMs) based on the homotopy method. The local bifurcation mechanism, which is different from conventional local resonance, is found. It is demonstrated that the local period doubling bifurcation of multiple cells will induce chaotic bands in the NAMMs, which can significantly expand the bandwidth for wave suppression. The saddle node bifurcation leads the system state jumping to the chaotic branch. Furthermore, the amplitude dependent dispersion properties enable NAMMs to manipulate elastic waves externally. Study of broadband tunable abilities reveals that stronger nonlinearity (larger nonlinear coefficient or higher amplitude) presents a broader nonlinear band gap and larger transmission loss. Moreover, with less attached mass, a low frequency and broadband are achievable simultaneously. This research may provide useful approaches for elastic wave control.
Ultra compact, broadband tunable optical bandstop filters based on a multimode one dimensional photonic crystal waveguide.
Venue: Optics express

In this paper, ultra compact, broadband tunable optical bandstop filters (OBSFs) based on a multimode one dimensional photonic crystal waveguide (PhCW) are proposed and systematically investigated. For the wavelengths in the mini stopband, the input mode is coupled to a contra propagating higher order mode by the PhCW and then radiates in a taper, resulting in a stopband at the output with low backreflection at the input. Three dimensional finite difference time domain method is employed to study the OBSFs. The influence of main structural parameters is analyzed, and the design is optimized to reduce the back reflection and band sidelobes. Using localized heating, we can shift the stopband and tune the bandwidth continuously by cascading the proposed structures. Due to the strong grating strength, our device provides a more compact footprint (40 mm x 1 mm) and much broader stopband (bandwidth of up to 84 nm) compared to the counterparts based on microrings, long period waveguide gratings, and multimode two dimensional PhCWs.
Tunable broadband terahertz wave plate based on one dimensional superconductor dielectric photonic crystals

The reflection phase difference between transverse electric (TE) and transverse magnetic (TM) waves in a one dimensional superconductor dielectric photonic crystal is studied by the transfer matrix method. The simulation results indicate that wide frequency regions exist within the terahertz range, in which the reflection phase differences can remain constant for a fixed incident angle and can vary continuously from 0 to p (or 0 to by increasing the incident angle. The shift and the number of such wide frequency regions can be manipulated through changing the thickness of the dielectric layers. The influences of temperature and the normal conducting electrons on the properties of the reflection phase difference are also numerically investigated. Based on these properties, a continuously tunable broadband terahertz wave plate can be designed.

The goal of interface management is to identify, define, control, and verify interfaces; ensure compatibility; provide an efficient system development; be on time and within budget; while meeting stakeholder requirements. This paper will present a successful seven step approach to interface management used in several NASA flight projects. The seven step approach using Model Based Systems Engineering will be illustrated by interface examples from the Materials International Space Station Experiment X (MISSE X) project. The MISSE X was being developed as an International Space Station (ISS) external platform for space environmental studies, designed to advance the technology readiness of materials and devices critical for future space exploration. Emphasis will be given to best practices covering key areas such as interface definition, writing good interface requirements, utilizing interface working groups, developing and controlling interface documents, handling interface agreements, the use of shadow documents, the importance of interface requirement ownership, interface verification, and product transition.
Converting U 500 regular insulin to insulin detemir and insulin lispro in a patient undergoing dietary changes in preparation for bariatric surgery.
Venue: American journal of health system pharmacy AJHP official journal of the American Society of Health System Pharmacists

The safe and effective conversion of human regular U 500 insulin (U 500R) to basal and bolus U 100 (insulin detemir and insulin lispro, respectively) in a patient undergoing a significant dietary change in preparation for bariatric surgery is described.  Conversion from U 100 to U 500R insulin has been described in the literature. There is, however, a paucity of information describing the reverse conversion (i.e. from U 500R to U 100 insulin) Whether converting to or from U 500R, patient safety is a primary concern. A 51 year old Caucasian woman with a 10 year history of type 2 diabetes mellitus, hypertension, and gastroparesis who was scheduled to undergo bariatric surgery was converted from U 500R to insulin detemir and insulin lispro preoperatively while undergoing significant diet changes. The patient's blood glucose values, diet, and activity levels were closely monitored daily by the interprofessional team over a 10 day preoperative period during which her regular diet was changed to a very low calorie, high protein diet; insulin doses were adjusted accordingly. Throughout this process, the patient did not experience any major hypoglycemic episodes. Close collaboration among interprofessional team members and a strong partnership with the patient were considered key factors in the successful conversion of insulin therapy.  Subcutaneous insulin therapy in a woman preparing for bariatric surgery was safely converted from U 500R to basal therapy with U 100 insulin detemir and with as needed boluses of U 100 insulin lispro. This occurred as the patient switched from a regular diet to a low calorie, high protein diet.
Culture and language in intercultural communication, English as a lingua franca and English language teaching: points of convergence and conflict

English as a lingua franca (ELF) studies, intercultural communication research and English language teaching (ELT) have all been concerned with ideas of 'successful' communication and the competencies needed to achieve this. While all three fields have recognised the importance of language and culture in understanding communication, little agreement has been reached on how to characterise the relationship between language and culture or how this relates to 'competent' communication. This chapter will therefore investigate the convergences and conflicts among the fields of ELF studies, applied linguistics research in intercultural communication and ELT in their perspectives on language and culture. These issues are explored, firstly, through a discussion of how culture has been conceived of in ELT and a critique of the often essentialist manner in which this has been done. This is followed by an examination of intercultural communication studies as related to language teaching. A distinction is drawn between essentialist approaches and more recent dynamic characterisation of intercultural communication. How culture and intercultural communication have been conceptualised in ELF is then presented, highlighting features of the intercultural communication literature which have been drawn on, but also a number of points of difference. It is argued here that ELF studies add to the growing body of post modernist thinking and research in applied linguistics that can inform intercultural communication research through underscoring the dynamic and fluid manner in which form, function and context are constructed in intercultural communication through English as a lingua franca. At the same time intercultural communication research can be of use to ELF studies through the extensive body of work exploring conceptions of intercultural communicative competence (ICC) Crucially, it is this focus on ICC and communicative competence that ELT, intercultural communication studies and ELF share. However, ELF research emphasises the importance of a conceptualisation of ICC in which language and culture are seen as emergent resources in intercultural communication which need to be approached critically. To this end the notion of intercultural awareness is proposed as a dynamic framework for intercultural competence. Such critical perspectives in understanding intercultural communication through ELF and associated notions of competencies have fundamental implications for ELT which have yet to be adequately taken up in theory or practice.
Automatic builder of class diagram (ABCD) an application of UML generation from functional requirements
Venue: Softw. Pract. Exp.

Software development life cycle is a structured process, including the definition of user requirements specification, the system design, and programming. The design task comprises the transfer of natural language specifications into models. The class diagram of Unified Modeling Language has been considered as one of the most useful diagrams. It is a formal description of user's requirements and serves as inputs to the developers. The automated extraction of UML class diagram from natural language requirements is a highly challenging task. This paper explains our vision of an automated tool for class diagram generation from user requirements expressed in natural language. Our new approach amalgamates the statistical and pattern recognition properties of natural language processing techniques. More than 1000 patterns are defined for the extraction of the class diagram concepts. Once these concepts are captured, an XML Metadata Interchange file is generated and imported with a Computer Aided Software Engineering tool to build the corresponding UML class diagram.
Handling E Waste in Malaysia: Management,Policies and Strategies

One of the concerns of life is the generation of waste. In today's modern life, the generation of the new type of waste is the waste of electrical and electronic equipment's or e waste becoming a crucial problems to solve. E waste containing both dangerous and valuable materials requiring a special treatment and recycling practices to avoid adverse environmental impacts and harmful impact on human health. Domestic ewaste generation in Malaysia has already climbed dramatically and forecasted to reach over a million tons in 2020. This increasing trend amount of e waste is due to the high demand on the production of electric and electrical equipment from the Malaysia's consumers. Various steps been taken by government in order to tackle the ever growing threat of e waste. This paper presents global and Malaysia e waste scenario, initiatives and practices in handling an e waste. Consequently, this paper suggest that e waste policy development is crucial in Malaysia and requires more customized approach and a strategies environment assessment as part of national policy planning.
Best Practices Article: Hitting the Target with Transition to Teaching in Mississippi's Poorest School Districts: High Retention Rates through Program Support, Resources, and Strategic Recruitment.

This program, known as Learning and Educating through Alternative Programs (LEAP) would address preparation and retention issues in teacher preparation. This article will tell the story of how this transition to teaching program used effective support, resources, and strategic recruiting in order to yield high retention rates in partner school district, often at nearly 90 percent during the first three years of teaching.
Conducting Polymers for Pseudocapacitive Energy Storage

Developing energy storage devices to be utilized within a rapidly advancing energy market requires a multipronged approach whereby material synthesis and engineering fundamentals combine to enable technological advances. These devices should be able to store a large amount of energy in a small, lightweight package, and should be able to distribute that energy quickly for high rate applications. Pseudocapacitors made from conducting polymers, which store charge via rapid reduction and oxidation reactions, are a particularly promising candidate. This perspective explores conductivity and charge storage mechanisms in conducting polymers and describes how synthetic strategies can affect these properties. We further develop chemical correlations that have been shown to enhance the performance of pseudocapacitive electrochemical capacitors fabricated from conducting polymers. Important device engineering strategies for improving the lifetime and applicability of pseudocapacitors are also discussed.
A Privacy Preserving and Copy Deterrence Content Based Image Retrieval Scheme in Cloud Computing
Venue: IEEE Transactions on Information Forensics and Security

With the increasing importance of images in people's daily life, content based image retrieval (CBIR) has been widely studied. Compared with text documents, images consume much more storage space. Hence, its maintenance is considered to be a typical example for cloud storage outsourcing. For privacy preserving purposes, sensitive images, such as medical and personal images, need to be encrypted before outsourcing, which makes the CBIR technologies in plaintext domain to be unusable. In this paper, we propose a scheme that supports CBIR over encrypted images without leaking the sensitive information to the cloud server. First, feature vectors are extracted to represent the corresponding images. After that, the pre filter tables are constructed by locality sensitive hashing to increase search efficiency. Moreover, the feature vectors are protected by the secure kNN algorithm, and image pixels are encrypted by a standard stream cipher. In addition, considering the case that the authorized query users may illegally copy and distribute the retrieved images to someone unauthorized, we propose a watermark based protocol to deter such illegal distributions. In our watermark based protocol, a unique watermark is directly embedded into the encrypted images by the cloud server before images are sent to the query user. Hence, when image copy is found, the unlawful query user who distributed the image can be traced by the watermark extraction. The security analysis and the experiments show the security and efficiency of the proposed scheme.
Robots, Industry 4.0 and Humans, or Why Assembly Work Is More than Routine Work

This article condenses the key findings of qualitative studies on assembly work. Grounded conceptually in considerations of the role of experiential knowledge and living labor capacity with regard to informal expertise and tacit knowledge, the empirical results challenge the dominant view of assembly work as routine tasks that could easily be replaced by robotics. The empirical basis comprised of 62 qualitative interviews in five assembly plants provides answers to two questions: Are there non routine aspects to be found in assembly work today? What exactly is the nature of experience in assembly work? The detailed research results are presented in three steps: the first focuses on the role of the non routine in core assembly tasks; the second discusses the important and increasing role played by interactive capabilities in assembly work to ensure high performance, quality, and a smooth material flow; and the third highlights the usually neglected role of assembly workers in processes of innovation and organizational learning. The concluding chapter discusses the findings from the perspective of new technological options in robotics, possible worker resistance and effects on employment.

The authors give a balanced, informed and compelling view on gaining the many benefits, as well as managing the downsides, of present and future technologies.
A pathological brain detection system based on kernel based ELM
Venue: Multimedia Tools and Applications

Magnetic resonance (MR) imaging is widely used in daily medical treatment. It could help in pre surgical, diagnosis, prognosis, and postsurgical processes. It could be beneficial for diagnosis to classify MR images of brain into healthy or abnormal automatically and accurately, since the information set MRIs generate is too large to interpret with manual methods. We propose a new approach with wavelet entropy as the features and the kernel based extreme learning machine (K ELM) to be the classifier. Our method employs 2D discreet wavelet transform (DWT) and calculates the entropy as features. Then, a K ELM is trained to classify images as pathological or healthy. A 10 x 10 fold cross validation is conducted to prevent overfitting. The method achieves the sensitivity as 97.48 the specificity as 94.44 and the overall accuracy as 97.04 based on 125 MR images. The performance suggests the classifier is robust and effective by comparison with the recently published approaches.

Problem Solving Therapy During Outpatient Stroke Rehabilitation Improves Coping and Health Related Quality of Life: Randomized Controlled Trial
Venue: Stroke

This study investigated whether problem solving therapy (PST) is an effective group intervention for improving coping strategy and health related quality of life (HRQoL) in patients with stroke.  In this multicenter randomized controlled trial, the intervention group received PST as add on to standard outpatient rehabilitation, the control group received outpatient rehabilitation only. Measurements were performed at baseline, directly after the intervention, and 6 and 12 months later. Data were analyzed using linear mixed models. Primary outcomes were task oriented coping as measured by the Coping Inventory for Stressful Situations and psychosocial HRQoL as measured by the Stroke Specific Quality of Life Scale. Secondary outcomes were the EuroQol EQ 5D 5L utility score, emotion oriented and avoidant coping as measured by the Coping Inventory for Stressful Situations, problem solving skills as measured by the Social Problem Solving Inventory Revised, and depression as measured by the Center for Epidemiological Studies Depression Scale.  Included were 166 patients with stroke, mean age 53.06 years (SD, 10.19) 53% men, median time poststroke 7.29 months (interquartile range, 4.90 10.61 months) Six months post intervention, the PST group showed significant improvement when compared with the control group in task oriented coping (P=0.008) but not stroke specific psychosocial HRQoL. Furthermore, avoidant coping (P=0.039) and the utility value for general HRQoL (P=0.034) improved more in the PST group than in the control after 6 months.  PST seems to improve task oriented coping but not disease specific psychosocial HRQoL after stroke >6 month follow up. Furthermore, we found indications that PST may improve generic HRQoL recovery and avoidant coping.
