In this paper, energy detectors are developed for wideband and ultra-wideband (UWB) pulse position modulation (PPM). Exact bit error probability (BEP) expressions are presented under different assumptions about the channel. More specifically, we present an expression for the instantaneous BEP for a specific channel realization as well as an expression for the average BEP for an i.i.d. zero-mean...

Benzo(e)pyrene (BeP) is a cocarcinogen with benzo(a)pyrene (BaP) and an anticarcinogen with 7,12-dimethylbenz(a)anthracene (DMBA) in mouse skin initiation-promotion assays (Slaga, T. J., Jecker, L., Bracken, W. M. and Weeks C. E. Cancer Lett. 7: 51-59, 1979). We have investigated the effects of BeP on the metabolic activation of BaP and DMBA in early-passage cultures of Syrian hamster embryo ce...

A histogram-based technique allows to estimate the bit error probability (BEP) of an optical signal suffering from distortion. At 10Gbit/s, we obtain good results even for high optical signal-to-noise ratios, i.e. for low BEP. Introduction A common technique to estimate the bit error probability (BEP) in optical communication systems uses a histogram generated by sampling the photocurrent corru...

Oxidation of low-density lipoprotein (LDL) is one of the major causative mechanisms in the development of atherosclerosis. In previous studies, we showed that minimally oxidized LDL (mmLDL) induced inflammatory responses in macrophages, macropinocytosis and intracellular lipid accumulation and that oxidized cholesterol esters (OxCEs) were biologically active components of mmLDL. Here we identif...

In the third year of the Link the Wiki track, anchor-to-BEP link discovery has been the focus besides the file-to-file link discovery. There are two collections, Wikipedia and Te Ara, used in 2009 for respective tasks. 5000 topics were randomly selected for the file-to-file task and 33 anchor-to-BEP topics were nominated by the participants. The Te Ara corpus is used for the first time and the ...

In order to establish emission limits to protect radio systems, the effect of the non-Gaussian properties of interference on the performance of coded radio transmission systems should be taken into account. In this paper, a simple closed-form expression for the bit error probability (BEP) of convolutional codes is developed for coherent BPSK systems assuming that the interfering signal is expre...

The efficiency of minimum-energy configuration searching algorithms is closely linked to the energy landscape structure of complex systems, yet these algorithms often include a number of steps of which the effect is not always clear. Decoupling these steps and their impacts can allow us to better understand both their role and the nature of complex energy landscape. Here, we consider a family o...

Neurobehavioral stress has been shown to promote tumor growth and progression and dampen the immune system. In this study, we investigated whether inhibiting stress hormone production could inhibit the development of mammary carcinoma and metastasis in a rat model of breast carcinogenesis. To enhance β-endorphin (BEP), the endogenous opioid polypeptide that boosts immune activity and decreases ...

We describe a program called SketchIT that uses a description of desired behavior to transform a sketch of a mechanical device into a “BEP-Model,” a parametric model with constraints that ensure the device produces the desired behavior. The program also generates alternative implementations for the design, each of which is represented as a BEP-Model. The program is based on qualitative configur...

β-Endorphin (BEP)-producing neuron in the hypothalamus plays a key role in bringing the stress axis to a state of homeostasis and maintaining body immune defense system. Long-term delivery of BEP to obtain beneficial effect on chemoprevention is challenging, as the peptides rapidly develop tolerance. Using rats as animal models, we show here that transplantation of BEP neurons into the hypothal...
