The paper aimed to determine the true identity of a presumed or commonly believed Sinarapan fish and compare their phylogenetic relationships by using DNA barcoding. The fish samples were collected by researchers from a fisheries research and development institution in April 2015 from four different lakes of Bicol Region, i.e., Lakes Buhi, Danao, Manapao and Bato. DNA was extracted using cetyl trimethyl ammonium bromide （CTAB） extraction buffer. The polymerase chain reaction （PCR） profile for the reaction was 94 ℃ for 10 min, followed by 35 cycles of 1 min at 94℃, 1 min at 48℃ and 1.5 min at 72℃, and a final extension of 10 min at 72℃. The CO 1 region with approximately 650 bp was amplified because of its capability to differentiate taxa. Sequencing was done by Macrogen while phylogenetic analysis was produced using a Molecular Evolutionary Genetics Analysis （MEGA） software version 6.0. The findings showed that CO1 can be used as a DNA marker in molecular identification of the fish samples. Samples from two of the four lakes were successfully sequenced. From basic local alignment search tool （BLAST） results, the maximum parsimony （MP） and neighbor-joining （N J） trees revealed that samples from Lakes Buhi and Bato are not species of Sinarapan but rather species of Leiopotherapon plumbeus and Rhinogobius giurinus, respectively. Furthermore, DNA barcoding is very useful in proving the true identity of unknown samples.

The author designed two algorithms for distributed cooperation among multiple video streams sharing common communication resources. The algorithms take advantage of an optimization framework that characterizes video packets such that joint resource allocation can be implemented not only over the packets of a single stream, but also across packets of different streams. The first algorithm enables collaboration among multiple video senders in an 802.11 CSMA/CA wireless network such that their joint performance is maximized. Via the algorithm, the users cooperatively establish transmission priorities based on the assigned characterizations of their video packets. The second technique allows for low-complexity joint bandwidth adaptation of multiple video streams at intermediate network nodes in the Internet in order to maximize the overall network performance. The author analyzes the advantages of the proposed algorithms over conventional solutions employed in such scenarios. It is shown that depending on system parameters such as available network data rate the proposed techniques can provide substantial gains in end-to-end performance.

This paper presents the fundamental optical concepts of designing multifocal ophthalmic lenses and the mathematical methods associated with them. In particular, it is shown that the design methodology is heavily based on differential geometric ideas such as Willmore surfaces. A key role is played by Hamilton's eikonal functions. It is shown that these functions capture all the information on the local blur and distortion created by the lenses. Along the way, formulas for computing the eikonal functions are derived. Finally,the author lists a few intriguing mathematical problems and novel concepts in optics as future projects.

Composite materials reinforced with carbon nanotubes were mechanical tested using Arcan test rig under Mode-I, Mode-II and mixed mode loading conditions to obtain their fracture properties. The butterfly composite specimens were fabricated with 0.02, 0.05 and 0.1 wt % CNTs. The polyester/CNT composite was fabricated using VRTM (Vacuum Resin Transfer Molding) where the CNTs were first functionalised to reach an optimum properties. Arcan test rig was designed and fabricated to work with the Shimadzu testing machine. The results show that the functionalised CNTs have improved the fracture behavior by acting as bridge between the cracked face. In addition, the fracture properties were not improved for the higher weight fraction of 0.1 wt% CNTs.

In this paper we study properties of the secondary Hochschild homology of the triple （A, B, ε） with coefficients in M. We establish a type of Morita equivalence between two triples and show that H.（（A,B,ε）; M） is invariant under this equivalence. We also prove the existence of an exact sequence which connects the usual and the secondary Hochschild homologies in low dimension~ allowing one to perform easy computations. The functoriality of H.（（A, B, ε）; M） is also discussed.

Dear Editor, Understanding how Kranz anatomy develops in C4 plants is a critical part of the current worldwide effort to transfer C4 photosynthesis into C3 plants, including rice. Recently, it was proposed that the Kranz architecture that supports C4 photosynthesis in maize leaves is an extension of the endodermal program, which is active in roots, stems, and petioles, and is ubiquitous in angiosperms （Slewinski et al., 2012; Slewinski, 2013）.
