Signal Article Reviews Samples For Students

Combinatorial communication is a process in which two (or more) holistic signals combine to produce different signals that have a different result than the sum of the results of the component signal. These are highly evident in humans and a little less in species of some non- human primates that scientists suggest that they are due to evolution of human language. The studies were carried out using the same methods as those of primate species because; combinatorial communication has been reported in communication systems of these species. The results led researchers to the assumption that the combinations seen in non-human primates are ...

Polyvinylidene fluoride polymer first exhibited the piezoelectric effect in the year 1969 followed by the pyroelectric effect some years later, leading to the development of numerous applications of pyroelectricity and piezoelectricity. PVDF possesses many attractive features as a tactile or touch sensor. Tactile sensors can be used to monitor skin conditions. They find use in minimally invasive surgery. Tanaka et al. developed an active palpitation sensor to detect hypertrophy and prostate cancer. Pyroelectric and piezoelectric polymers help in energy conversion. The Energy Harvesting Eel device created by Taylor et al. used piezoelectric polymers for the conversion of mechanical flow energy ...

Connective tissue growth factor induces collagen I expression in human lung fibroblasts through the Rac1/MLK3/JNK/AP-1 pathway

Many lung inflammatory diseases present pulmonary fibrosis as one of the symptoms, which is characterized by shortness of breath, chronic coughing and discomfort in the chest. It causes modifications of the lung tissues due to overgrowth, hardening and scarring. This occurs mainly due to deposition of collagen, an extracellular matrix (ECM) protein, whose turnover is regulated by fibroblast. Fibroblast is an important cell regulator that is enlisted by a site of injury. This process is driven by release of transforming growth factor-β (TGF-β), platelet-derived growth factor, interleukin-6 (IL-6), and IL-8/CXCL8.
Previously, fibroblast was thought to express no or very ...

Purpose of the article

The article seeks to find out the average energy that is required for every scintillation photon as well as the energy resolutions present in crystals of sodium iodide that is activated with thallium and cesium iodide that is doped with thallium for gamma rays. Through this information, that author can comprehend the pathways that radiation energy to luminescence takes in scintillators. This information is important if one is to draw a comparison between scintillation yields from various scintillators. As such, this article adduces that the use of quantities that are related to scintillation efficiency is appropriate in understanding these pathways. ...

Introduction

The Wide-Band Code Division Multiple Access (W-CDMA) is a third generation handset system that achieves high data transmission by utilizing a wider spectrum frequency. Issues that arise in handsets such as a low spectral growth and maintenance of modulation accuracy require a low adjacent channel leakage power ratio (ACLR) especially in the case of the W-CDMA handset systems. High linearization in the portable W-CDMA systems can be improved by increasing the gain compression point that creates the AM-AM distortion. As such this can be achieved by using an on-chip linearizer.
A new on-chip active bias circuit can be used ...

For my discourse analysis, I have chosen the Lapse for Words Transcript since I found it interesting and I believe I can discuss many things through it. It was an interesting conversation since it does happen almost everyday – people dating and breaking over the phone, which of course, since two people conversing couldn’t see each other (speaker and the listener), would imply different things to each other.
Also, the transcription used several overlap symbols, elapsed time, punctuation for intonation, stress (pitch and volume), aspiration, being unsure of accuracy and nonverbal sounds such as breathing and sighing.
First, let ...

Introduction:

The function of many living organisms is coupled with a vast array of cells .These units in turn serve as role playing agents for the fundamental physiology that determines the well being of organisms. However, variations in cellular environment are thought to regulate cell growth, division and survival. A network of molecular pathways or signaling events are interlinked with the cellular functions .Alterations in this specific functional aspect could lead to unnecessary complications which may lead to health abnormalities. In such context , the present description is concerned with highlighting about mTOR Signaling in Carcinogenesis.
mTOR stands for mammalian target ...
