Mining compact bag-of-patterns for low bit rate mobile visual search.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Ji R, Duan LY, Chen J, Huang T, Gao W.
PMID: 24835227
IEEE Trans Image Process. 2014 Jul;23(7):3099-113. doi: 10.1109/TIP.2014.2324291.

Visual patterns, i.e., high-order combinations of visual words, contributes to a discriminative abstraction of the high-dimensional bag-of-words image representation. However, the existing visual patterns are built upon the 2D photographic concurrences of visual words, which is ill-posed comparing with...

Optofluidic fabrication for 3D-shaped particles.

Nature communications

Paulsen KS, Di Carlo D, Chung AJ.
PMID: 25904062
Nat Commun. 2015 Apr 23;6:6976. doi: 10.1038/ncomms7976.

Complex three-dimensional (3D)-shaped particles could play unique roles in biotechnology, structural mechanics and self-assembly. Current methods of fabricating 3D-shaped particles such as 3D printing, injection moulding or photolithography are limited because of low-resolution, low-throughput or complicated/expensive procedures. Here, we...

Mesoporous TiO₂ Bragg stack templated by graft copolymer for dye-sensitized solar cells.

PMID: 24980936
Sci Rep. 2014 Jul 01;4:5505. doi: 10.1038/srep05505.

Organized mesoporous TiO₂ Bragg stacks (om-TiO₂ BS) consisting of alternating high and low refractive index organized mesoporous TiO₂ (om-TiO₂) films were prepared to enhance dye loading, light harvesting, electron transport, and electrolyte pore-infiltration in dye-sensitized solar cells (DSSCs). The...

Nature communications

Theobald W, Solodov AA, Stoeckl C, Anderson KS, Beg FN, Epstein R, Fiksel G, Giraldez EM, Glebov VY, Habara H, Ivancic S, Jarrott LC, Marshall FJ, McKiernan G, McLean HS, Mileham C, Nilson PM, Patel PK, Pérez F, Sangster TC, Santos JJ, Sawada H, Shvydky A, Stephens RB, Wei MS.
PMID: 25503788
Nat Commun. 2014 Dec 12;5:5785. doi: 10.1038/ncomms6785.

The advent of high-intensity lasers enables us to recreate and study the behaviour of matter under the extreme densities and pressures that exist in many astrophysical objects. It may also enable us to develop a power source based on...

High-Performance Flexible All-Solid-State Supercapacitor from Large Free-Standing Graphene-PEDOT/PSS Films.

Scientific reports

Liu Y, Weng B, Razal JM, Xu Q, Zhao C, Hou Y, Seyedin S, Jalili R, Wallace GG, Chen J.
PMID: 26586106
Sci Rep. 2015 Nov 20;5:17045. doi: 10.1038/srep17045.

Although great attention has been paid to wearable electronic devices in recent years, flexible lightweight batteries or supercapacitors with high performance are still not readily available due to the limitations of the flexible electrode inventory. In this work, highly...

Large work function difference driven electron transfer from electrides to single-walled carbon nanotubes.

Nanoscale

Menamparambath MM, Park JH, Yoo HS, Patole SP, Yoo JB, Kim SW, Baik S.
PMID: 24956225
Nanoscale. 2014 Aug 07;6(15):8844-51. doi: 10.1039/c4nr01629g.

A difference in work function plays a key role in charge transfer between two materials. Inorganic electrides provide a unique opportunity for electron transfer since interstitial anionic electrons result in a very low work function of 2.4-2.6 eV. Here...

How will I be remembered? Conserving the environment for the sake of one's legacy.

Psychological science

Zaval L, Markowitz EM, Weber EU.
PMID: 25560825
Psychol Sci. 2015 Feb;26(2):231-6. doi: 10.1177/0956797614561266. Epub 2015 Jan 05.

Long time horizons and social distance are viewed as key psychological barriers to proenvironmental action, particularly regarding climate change. We suggest that these challenges can be turned into opportunities by making salient long-term goals and motives, thus shifting preferences...

Parameter modeling for nanopore lonic field effect transistors in 3-D device simulation.

Journal of nanoscience and nanotechnology
