Fiberstar, Inc. (, a global market leader in clean label food ingredient solutions for the food and beverage industry announced the winners to the Citri-Fi 125 Student Innovation Contest. Citri-Fi 125, a natural, non-GMO citrus fiber is one of the most recent additions to the Citri-Fi portfolio. To find new uses for this natural citrus fiber, Fiberstar launched a global innovation contest targeting University students. Over 25 applicants, globally, submitted a proposal in how to use the Citri-Fi 125. “This is the first time a program like this has been created, so we are pleased with the interest from the applicants,” says Fiberstar, Inc. President and CEO, John Haen. “We continue to support University food science programs by offering students opportunities to create food ingredient solutions for the real world.” A panel of judges ranked the students’ applications based on originality of concept, justification/market need, ingredient commercial feasibility, technical feasibility and quality of their report. A total of $25,000 was awarded amongst the six winning proposals. The following winning teams and applications are: 1st Place: Citrus Fiber as an Effective Fat Blocker in Fried Seafood: Oregon State University Seafood Research and Education Center, U.S. (Dr. Jae Park, Kaitlin Junes and Angela Hunt). Citri-Fi 125 used in a coating formulation to reduce oil pick-up not only provides potential cost savings to processors due to reduced oil usage, but this also provides manufacturers opportunities to reduce fat and calories. The study also showed yield improvement due to increased pick-up and reduced cooking losses. 2nd Place: Reduced Fat Instant Laksa Paste: Surya University, Indonesia (Sylviana, Meutia Wafa' Khairunnisa Hakim, Amelia Adinda and Bryan Raharja). Citri-Fi 125 is used to reduce the amount of coconut milk used in Laksa paste to provide potential cost savings and fat reduction. Citri-Fi 125 provides emulsification stabilization and improved mouthfeel to simulate the texture of the full-fat version. This may be applicable to other coconut milks pastes, spreads, beverages and soups found not only in Asia, but also in other parts of the world due to the growing use of coconut. 3rd Place: Citri-Crunch Healthy Savory Extruded Pork Snack: Washington State University, U.S. (Ryan Kowalski, Bon-Jae Gu, Maria Dian Pratiwi Masli, Siyuan Wang and Hongchao Zhang). Citri-Fi 125 helped reduce the oil uptake and improved the flavor by enhancing the umami flavor of monosodium glutamate when reducing the sodium. This not only aligns with the market’s need for healthier snacks, but also offers snack manufacturers cost savings opportunities in less oil usage. 4th Place: Chicken Sausage with Reduced Oil & Improved Sensory: University of Peradeniya, Sri Lanka (Miss A.M. Aruni Shanika, Dr. Himali Samaraweera, Nirupa Edirisinghe, Hashinee Medika Ariyasena and Nuwan Jayawardena). Citri-Fi 125 provided emulsification stabilization and texturizing to help reduce the oil by at least 30% while maintaining a full-fat mouthfeel. This provides cost savings and health benefits due to the fat/caloric reduction. 5th Place: Calcium Fortification to Increase Viscosity and Enhance Gelling Properties: University of Guelph, Canada (Lisa Indris). Incorporating calcium with Citri-Fi 125 in liquid food formats improves the viscosity and provides improved stabilization. This enhanced feature opens doors in the natural dairy category where stabilization and mouthfeel are desired and needed. 6th Place: Natural Color Stabilizer in Berry Yammee Topping: Cornell University, U.S. (Fiona Harnischfeger, Sofía Lara, Victoria Chen, Katrina Cariño, Ana Chang, Sierra Jamir and Shiyu Cai). Citri-Fi 125 stabilizes natural colors during shelf-life to prevent phase separation and color bleeding. This benefit is crucial for consumer acceptance when using vibrant natural colors to indicate freshness. Fiberstar also offers other citrus fiber solutions via 100 series line which contains different fiber content than the 125 series, the 200 series which is citrus fiber and guar gum and the 300 series which is the citrus fiber and xanthan gum. The Citri-Fi citrus fiber product lines provide food manufacturers clean label texturizing solutions for various food products including bakery, beverages, dressings, meats, sauces and dairy. “We are excited to enhance our formulating tool box by promoting Citri-Fi 125 citrus fiber. Our team will continue working closely with our Customers to provide superior technical service support, quality product and new ideas especially those generated from the most recent innovation contest. And we look forward to connecting with Universities and students in the future to continue the collaboration.” For more information about the Innovation Contest applications, please contact Dr. Brock Lundberg at (651) 271-0328

Surface wrinkles driven by elastic instabilities have attracted significant interest in the field of materials science and engineering. They are simple and readily fabricated with various patterns of tunable size, morphology and surface topography from a wide range of material systems. Recently, they have been investigated as a new type of dry adhesives. In this review, after a brief introduction of different methods to prepare wrinkle surfaces, we focus on the investigation of dry adhesion mechanisms in different material systems. By exploiting wrinkle dimension, morphology, modulus, curvature, and different contacting surfaces (flat, hemispherical, spherical) and their complementarity, we show adhesion enhancement, reduction and selectivity. By comparing experimental results with theoretical predictions, we aim to provide a guideline to design and engineer wrinkle-based dry adhesives. Several examples of applications of engineered wrinkles are also demonstrated, including pick, release and transfer of nanoparticles and bulk materials, and gecko-like hybrid adhesives. The review is concluded with perspectives on the wrinkling technology for smart dry adhesives. This journal is © the Partner Organisations 2014.

The Indonesian throughflow (ITF) from the Pacific to the Indian Ocean plays an important role in global ocean circulation and climate. Yet, continuous ITF measurement is difficult and expensive. The longest time series of in situ measurements of the ITF to date were taken in the Makassar Strait, the main pathway of the ITF. Here we have demonstrated a plausible approach to derive the ITF transport proxy using satellite altimetry sea surface height (SSH), gravimetry ocean bottom pressure (OBP) data, in situ measurements from the Makassar Strait from 1996 to 1998 and 2004 to 2011, and a theoretical formulation. We first identified the optimal locations of the correlation between the observed ITF transport through the Makassar Strait and the pressure gradients, represented by the SSH and OBP differences between the Pacific and Indian Oceans at a 1° × 1° horizontal resolution. The optimal locations were found centered at 162°E and 11°N in the Pacific Ocean and 80°E and 0° in the Indian Ocean, then were used in the theoretical formulation to estimate the throughflow. The proxy time series follow the observation time series quite well, with the 1993-2011 mean proxy transport of 11.6 ± 3.2 Sv southward, varying from 5.6 Sv during the strong 1997 El Niño to 16.9 Sv during the 2007 La Nina period, which are consistent with previous estimates. The observed Makassar mean transport is 13.0 ± 3.8 Sv southward over 2004-2011, while the SSH proxy (for the same period) gives an ITF mean transport of 13.9 ± 4.1 Sv and the SSH + OBP proxy (for 2004-2010) is 15.8 ± 3.2 Sv. © 2015.

The presence of significant tidal mixing in the Indonesian seas is well established from both observations and numerical modeling. One indicator is a clear spring-neap cycle in satellite sea surface temperature (SST) measurements, as first shown by Ffield and Gordon. Their early results are here updated with SST data of considerably higher spatial and temporal resolution. The largest fortnightly signals are found to be localized to relatively small straits, channels, and sills, while the deep basin of the Banda Sea displays little significant signal. A broader region of somewhat enhanced signal surrounds the Seram Sea. The high resolution of the modern SST data is especially critical for mapping the complex fortnightly signals that arise in, and especially south of, the major straits of the Lesser Sunda Island chain. ©2016.

One of the methods in understanding the real microstructure of auxetic material is by separating it into several simplified structures that have distinct mechanisms. Among those simplified structures are chiral and re-entrant structures. This paper adapts a 2D re-entrant structure for a 3D auxetic structure. A re-entrant structure is chosen due to its fundamental characteristics underlying the main characteristics of auxetic materials. The energy methods of solid mechanics along with numerical methods are used to study the fundamental concept of auxetic materials. Understanding the characteristics of the re-entrant structure will lead to the better comprehension of other structures of auxetic materials, which will eventually contribute to the advance of research in this new class of materials. © 2014 Elsevier Ltd.

Attribute Oriented Induction High level Emerging Pattern (AOI-HEP) as a new data mining technique, combines two data mining techniques i.e. Attribute Oriented Induction (AOI) and Emerging Patterns (EP). The AOI-HEP application is implemented as a hybrid between AOI characteristic rule mining and HEP algorithms. AOI-HEP combines the powerful features of AOI and EP by using concept hierarchy in AOI to generalize into high level data and applying growth rates in EP and produces powerful discrimination for high level data. AOI-HEP can be implemented to discriminate datasets such as finding bad and good customers for banking loan systems or credit card applicants and etc. Meanwhile, AOI-HEP can be implemented to mine similar patterns such as similar customer loan patterns or similar customer credit card rating and etc. Since AOI-HEP is a new data mining technique, then future research can be explored such as inverse discovery learning, learning more than two datasets, learning other knowledge rules and etc. AOI-HEP future research will give research idea for data mining researchers community particularly for bachelor and master degree students. Indeed, AOI-HEP as new comer data mining technique will be completed in discovery process, having rich interesting patterns and become interested mining technique. © 2014 IEEE.

Infectious myonecrosis virus (IMNV) is a pathogen of penaeid shrimp, most notably the whiteleg shrimp Litopenaeus vannamei. First discovered in L. vannamei from Brazilian aquaculture farms in 2003, IMNV was additionally confirmed in L. vannamei from Indonesian farms in 2006 and has since been found in numerous provinces there. Only two complete sequences of IMNV strains have been reported to date, one strain from the Brazilian state of Piauí collected in 2003 and another from the Indonesian province of East Java collected in 2006. In this study, we determined the complete sequences of two additional Indonesian strains, one from Lampung province collected in 2011 and another from East Java province collected in 2012. We also determined partial sequences for six other strains to enhance phylogenetic comparisons, which have heretofore been limited by the small number of reported sequences, including only one for an Indonesian strain. The new results demonstrate clear genetic diversification of IMNV between Indonesia and Brazil, as well as within Indonesia. Analyses of conserved sequence motifs suggest a revised RNA pseudoknot prediction for ribosomal frameshifting. © 2014 Elsevier B.V.

This paper is extended version from previous paper which proposed AOI-HEP as novel data mining technique. This paper will explain how AOI-HEP mining technique can be used to mine frequent pattern. AOI-HEP is influenced by Attribute Oriented Induction (AOI) and Emerging Pattern (EP) mining techniques by applying AOI characteristic rule algorithm and improvement EP growth rate. The experiment used adult dataset from UCI machine learning repository with 48842 instances, run in 3 seconds and the instances were discriminated between government and non government concepts based on learning on workclass attribute. AOI-HEP mining interest for frequent pattern will be influenced by learning on their chosen attribute. The experiments showed that adult dataset which learn on workclass attribute had AOI-HEP mining interest for frequent pattern and there are four frequent patterns which have strong discrimination rule. Meanwhile, extended experiments upon adult dataset which learn on marital-status attribute showed there is no AOI-HEP mining interest for frequent pattern. © 2014 IEEE.

The paper describes the power and area efficient carry select adder (CSA). Firstly, CSA is one of the fastest adders used in many data-processing systems to perform fast arithmetic operations. Secondly, CSA is intermediate between small areas but longer delay Ripple Carry Adder (RCA) and a larger area with shorter delay carry look-ahead adder. Third, there is still scope to reduce area in CSA by introduction of some add-one scheme. In Modified Carry Select Adder (MCSA) design, single RCA and BEC are used instead of dual RCAs to reduce area and power consumption with small speed penalty. The reason for area reduction is that, the number of logic gates used to design a BEC is less than the number of logic gates used for a RCA design. Thus, importance of BEC logic comes from the large silicon area reduction when designing MCSA for large number of bits. MCSA architectures are designed for 8-bit, 16-bit, 32-bit and 64-bit respectively. The design has been synthesized at 90nm process technology targeting using Xilinx Spartan-3 device. Comparison results of modified CSA with conventional CSA show better results and improvements. © 2013 IEEE.

As the adhesion quality plays an important role in determining the mechanical performance and environmental stability of most types of fibre-metal laminates (FMLs), investigating the interfacial fracture properties becomes one of the key factors for the improvement. Adhesion of a self-reinforced polypropylene (SRPP) and glass fibre reinforced polypropylene (GFPP) based FML is evaluated experimentally. Single Cantilever Beam (SCB) tests were performed to access interfacial fracture energy (G. c) of the bi-material laminates and their associated interlayer materials. Simulations mimicking the experiments were also performed. The energy needed to fracture was obtained experimentally and also via stress intensity factor from the simulations. The test results show that good adhesion between the aluminium and fibre reinforced thermoplastics can be achieved using a sulphuric acid anodising surface pre-treatment. Further examination has shown that the edges of the test samples highlighted the presence of significant fibre bridging in the SRPP and plastics deformation in the GFPP. © 2014 Elsevier Ltd.
