Ma K, Zhao T, Zeng K, Wang Z, Lyon AR, Munson SA, Renn BN.
PMID: 26208349
IEEE Trans Image Process. 2015 Dec;24(12):4673-85. doi: 10.1109/TIP.2015.2460015. Epub 2015 Jul 22.

Color-to-gray (C2G) image conversion is the process of transforming a color image into a grayscale one. Despite its wide usage in real-world applications, little work has been dedicated to compare the performance of C2G conversion algorithms. Subjective evaluation is...

dipIQ: Blind Image Quality Assessment by Learning-to-Rank Discriminable Image Pairs.

IEEE Trans Image Process. 2017 Aug;26(8):3951-3964. doi: 10.1109/TIP.2017.2708503. Epub 2017 May 26.

Objective assessment of image quality is fundamentally important in many image processing tasks. In this paper, we focus on learning blind image quality assessment (BIQA) models, which predict the quality of a digital image with no access to its...

Transradial Primary Percutaneous Coronary Intervention.

Despite advances in antithrombotic and antiplatelet therapy, bleeding complications remain an important cause of morbidity and mortality in patients with acute ST segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). Many bleeding events are related to...

High dynamic range image compression by optimizing tone mapped image quality index.

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

Ma K, Yeganeh H, Zeng K, Wang Z.
PMID: 26011881
IEEE Trans Image Process. 2015 Oct;24(10):3086-97. doi: 10.1109/TIP.2015.2436340.

Tone mapping operators (TMOs) aim to compress high dynamic range (HDR) images to low dynamic range (LDR) ones so as to visualize HDR images on standard displays. Most existing TMOs were demonstrated on specific examples without being thoroughly evaluated...

Lipid transfer proteins are encoded by a small multigene family in Arabidopsis thaliana.

Plant science : an international journal of experimental plant biology

Arondel12 V, Vergnolle2 C, Cantrel C, Kader J.
PMID: 10940464
Plant Sci. 2000 Aug 08;157(1):1-12. doi: 10.1016/s0168-9452(00)00232-6.

Lipid transfer proteins (LTPs) are small, basic and abundant proteins in higher plants. They are capable of binding fatty acids and of transferring phospholipids between membranes in vitro. LTPs from this family contain a signal peptide and are secreted...

Universal scaling in transient creep.

Physical review letters

Dysthe DK, Podladchikov Y, Renard F, Feder J, Jamtveit B.
PMID: 12484959
Phys Rev Lett. 2002 Dec 09;89(24):246102. doi: 10.1103/PhysRevLett.89.246102. Epub 2002 Nov 20.

We present experimental evidence that pressure solution creep does not establish a steady-state interface microstructure as previously thought. Conversely, pressure solution controlled strain and the characteristic length scale of interface microstructures grow as the cubic root of time. Transient...

Rapid on-chip genetic detection microfluidic platform for real world applications.

Biomicrofluidics

Senapati S, Mahon AR, Gordon J, Nowak C, Sengupta S, Powell TH, Feder J, Lodge DM, Chang HC.

The development of genetic detection protocols for field applications is an important aspect of modern medical diagnostic technology and environmental monitoring. In this paper, we report a rapid, portable, and inexpensive DNA hybridization technique using a bead-based microfluidic platform...

Injection-locking optimization in unstable resonators.

Applied optics

Kedmi J, Treves D.
PMID: 20332894
Appl Opt. 1981 Jun 15;20(12):2108-12. doi: 10.1364/AO.20.002108.

The problem of transverse-mode matching between the lowest-loss mode of a confocal unstable resonator and a Gaussian beam, which is injected into the resonator through a coupling hole in its back mirror, is analyzed. It is found that in...

Large-scale mammalian cell culture: Design and use of an economical batch suspension system.

Biotechnology and bioengineering

Tolbert WR, Schoenfeld RA, Lewis C, Feder J.
PMID: 18546464
Biotechnol Bioeng. 1982 Jul;24(7):1671-9. doi: 10.1002/bit.260240717.

Large-scale mammalian cell culture in the absence of antibiotics requires stringent conditions of sterility for all vessels, procedure, and systems used. Application of existing fermentation technology suffers from the differences between mammalian and bacterial cultures. Relatively simple and inexpensive...
