PMID: 25610883
Neurol Neuroimmunol Neuroinflamm. 2015 Jan 14;2(1):e59. doi: 10.1212/NXI.0000000000000059. eCollection 2015 Feb.

OBJECTIVE: This study examined neurologic abnormalities (as measured by proton magnetic resonance spectroscopy imaging and diffusion tensor imaging), neurocognitive performance, and fatigue among a sample of adults with hepatitis C virus (HCV). We hypothesized that HCV+ individuals would demonstrate...

Treatment of PBMC with the CD4-specific mAb BT-061 induces CD4 down-modulation of T cells. Here we report that addition of BT-061 to purified T cells did not confer this effect, whereas incubation of T cells in BT-061 coated wells...

A blue luminescent MOF as a rapid turn-off/turn-on detector for H2O, O2 and CH2Cl2, MeCN: ∞³[Ce(Im)3ImH]·ImH.

Dalton transactions (Cambridge, England : 2003)

Meyer LV, Schönfeld F, Zurawski A, Mai M, Feldmann C, Müller-Buschbaum K.
PMID: 25623757
Dalton Trans. 2015 Mar 07;44(9):4070-9. doi: 10.1039/c4dt03578j.

The blue emitting luminescent MOF ∞³[Ce(Im)3ImH]·ImH forms a 3D-framework with Kagomé net topology. The framework exhibits an intense blue luminescence which can be retained upon activation of the MOF with the formula ∞³[Ce(Im)3ImH]. The luminescence is metal-based due to...

Spatial representations of place cells in darkness are supported by path integration and border information.

Frontiers in behavioral neuroscience

Zhang S, Schönfeld F, Wiskott L, Manahan-Vaughan D.
PMID: 25009477
Front Behav Neurosci. 2014 Jun 24;8:222. doi: 10.3389/fnbeh.2014.00222. eCollection 2014.

Effective spatial navigation is enabled by reliable reference cues that derive from sensory information from the external environment, as well as from internal sources such as the vestibular system. The integration of information from these sources enables dead reckoning...

Comparison of measured and calculated emission probabilities for K and L X-rays following radioactive disintegration processes.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Schönfeld E, Schötzig U.
PMID: 11258528
Appl Radiat Isot. 2001 May;54(5):785-91. doi: 10.1016/s0969-8043(00)00321-3.

The program EMISSION has been developed at the Physikalisch-Technische Bundesanstalt (PTB). It allows emission probabilities to be calculated for K and L X-rays following radioactive disintegration processes. This program was already applied to the calculation of total K X-ray...

Standardization and photon emission probabilities in the decay of 237Np/233Pa.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Schotzig U, Schonfeld E, Janszen H.
PMID: 10800725
Appl Radiat Isot. 2000 Apr;52(4):883-9. doi: 10.1016/s0969-8043(99)00137-2.

The activity concentration of a 237Np solution was determined by 4pialpha counting, by alpha particle spectroscopy with defined solid angle and by liquid scintillation counting (LSC). These methods yielded results which differ by less than 0.1% from the mean,...

Comments on "On the invertibility of morphological representation of binary images" [and reply].

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

Jang BE, Chin RT, Charif-Chefchaouni M, Schonfeld D.
PMID: 18285139
IEEE Trans Image Process. 1996;5(3):529-32. doi: 10.1109/83.491332.

The authors comments that Charif-Chefchaouni and Schonfeld (see ibid., vol.3, no.6, p.847, 1994) investigated the invertibility of a morphological representation of binary images and determined the necessary and sufficient conditions for its inverse. The authors show that one of...

Attraction-repulsion expectation-maximization algorithm for image reconstruction and sensor field estimation.

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

Hong H, Schonfeld D.
PMID: 19502130
IEEE Trans Image Process. 2009 Sep;18(9):2004-11. doi: 10.1109/TIP.2009.2024574. Epub 2009 Jun 05.

In this paper, we propose an attraction-repulsion expectation-maximization (AREM) algorithm for image reconstruction and sensor field estimation. We rely on a new method for density estimation to address the problems of image reconstruction from limited samples and sensor field...

IEEE Trans Image Process. 2009 Jun;18(6):1304-13. doi: 10.1109/TIP.2009.2017166. Epub 2009 Apr 17.

In this paper, we propose a novel solution to an arbitrary noncausal, multidimensional hidden Markov model (HMM) for image and video classification. First, we show that the noncausal model can be solved by splitting it into multiple causal HMMs...
