This paper presents a simulation based energy consumption analysis of a heterogeneous network (HetNet) consisting of Long Term Evolution (LTE) macro-cells and LTE femto-cells. Two potential areas of energy savings are evaluated, namely, sleep modes and spectrum assignment. Sleep modes are demonstrated with practical component level power models, resulting considerable energy savings. Three spec...

BACKGROUND Pre- and postoperative imaging is important and essential for evaluation of the results of rhinoplasty surgery. Two-dimensional photographs are used routinely for this purpose, but have several disadvantages as opposed to three-dimensional imaging techniques, such as stereophotogrammetry. This study is the first to describe the measurement of rhinoplasty results using stereophotogram...

Layered hybrid organic perovskites (HOPs) structures are a class of low-cost two-dimensional materials that exhibit outstanding optical properties, related to dielectric and quantum confinement effects. Whereas modeling and understanding of quantum confinement are well developed for conventional semiconductors, such knowledge is still lacking for 2D HOPs. In this work, concepts of effective mas...

Morton-Firth and Bray's stochastic simulator (StochSim) and Gillespie's stochastic simulation algorithm (SSA) are two important methods for stochastic modelling and simulation of biochemical systems. They have been widely applied to different biological problems. A key question is discussed here: Are these two methods equivalent? These two methods are compared using fundamental probability anal...

A unique organically-templated vanadium(IV) oxyfluoride, [pyH][V(2)O(2)F(5)] has been prepared using an ionothermal approach. This compound has a novel layered structure which may be considered as arising via condensation of previously known 'ladder-like' structural building units. This suggests that ionothermal synthesis may provide a more effective route to extended network structures in thes...

Optical imaging techniques offer simplistic while highly sensitive modalities for molecular imaging research. In this chapter, the major instrumental necessities for microscopic and whole-animal imaging techniques are introduced. Subsequently, the resulting imaging modalities using visible or near-infrared light are presented and discussed. The aim is to show the current capabilities and applic...

Tomographic diffractive microscopy is a three-dimensional imaging technique that reconstructs the permittivity map of the probed sample from its scattered field, measured both in phase and in amplitude. Here, we detail how polarization-resolved measurements permit us to significantly improve the accuracy and the resolution of the reconstructions, compared to the conventional scalar treatments u...

This review article aims to describe and discuss the imaging techniques most commonly used in medicine and dentistry to obtain three-dimensional images of the craniofacial complex. Three-dimensional imaging techniques provide extensive possibilities for the detailed and precise analysis of the whole craniofacial complex, for virtual (on-screen) simulation and real simulation of orthognathic sur...

Imaging is one of the most important tools for orthodontists to evaluate and record size and form of craniofacial structures. Orthodontists routinely use 2-dimensional (2D) static imaging techniques, but deepness of structures cannot be obtained and localized with 2D imaging. Three-dimensional (3D) imaging has been developed in the early of 1990's and has gained a precious place in dentistry, e...

Echocardiography accounts for nearly half of all cardiac imaging techniques. It is a widely available and adaptable tool, as well as being a cost-effective and mainly a non-invasive test. In addition, echocardiography provides extensive clinical data, which is related to the presence or advent of different modalities (tissue Doppler imaging, speckle tracking imaging, three-dimensional mode, con...
