B. Wu, P. Qu, J. Yuan, G. X. Shen MRI Lab, Department of Electrical and Electronic Engineering, The University of Hong Kong, Hong Kong INTRODUCTION Minimizing the mutual coupling among array elements is necessary for parallel MRI. Preamplifiers with extremely low input-impedance [1] and capacitive decoupling networks [2, 3] have become the primary techniques for decoupling arbitrarily placed co...

OBJECTIVES Transoral laser microsurgery (TLM) has been increasingly used in lieu of total laryngectomy to treat malignancy after definitive radiation. There are few data in the literature regarding functional outcomes. We retrospectively reviewed voice and swallowing outcomes in patients who underwent TLM for recurrent laryngeal carcinoma. STUDY DESIGN Case series with chart review. SETTING...

A supercondensed TLM node for modelling inhomogeneous anisotropic media on an arbitrarily graded mesh without using stubs is developed. It requires less storage, computationally is more efficient and can operate on a higher time step then existing TLM nodes. Complete derivation, implementation and validation of the new node are presented in the paper. Introduction Transmission-Line Modelling (T...

Asteroids are the origin point for most meteorites impacting Earth. Terrestrial meteorite samples provide evidence of what actually occurred in early solar system at formation location meteorite, and when it occurred. The ability to connect a sample an asteroid parent body provides its starting as meteoroid. To date, only handful chondritic types have been credibly connected parent. For past tw...

Abstract Four-dimensional variational (4D-Var) data assimilation (DA) is developed for a coupled atmosphere–ocean quasigeostrophic application. Complications arise in (CDA) systems due to the presence of multiple spatiotemporal scales. Various formulations background error covariance matrix ( ), using different localization strategies, are explored evaluate their impact on 4D-Var performance CD...

Gene expression heterogeneity is a key driver for microbial adaptation to fluctuating environmental conditions, cell differentiation and the evolution of species. This phenomenon has therefore enormous implications, not only for life in general, but also for biotechnological applications where unwanted subpopulations of non-producing cells can emerge in large-scale fermentations. Only time-laps...

Typical features of the Transmission Line Matrix (TLM) algorithm in connection with stub loading techniques and prone to be hidden by common frequency domain formulations are elucidated within the propagator approach. In particular, the latter reflects properly the perturbative character of the TLM scheme and its relation to gauge field models. Internal ‘gauge’ degrees of freedom are made expli...

Bacterial surface adsorption reactions are influenced by electric field effects caused by changes in ionic strength; however, existing datasets are too sparse to definitively constrain these differences or to determine the best way to account for them using thermodynamic models. In this study, we examine the ionic strength dependence of proton and metal adsorption onto the surfaces of Pseudomon...

BACKGROUND Appreciable local recurrence rates observed in patients with margin-negative, transoral laser microsurgery (TLM)-treated oral cavity squamous cell carcinoma (SCC) necessitate identification of new prognosticators for local control and survival. A histopathologic index (Brandwein-Gensler score [BGS]) and intrinsic/iatrogenic/chronic conditions causing immune compromise are investigate...
