I thank Lewis et al. for their letter [1] in response to my recent review article in TREE [2], but argue here that the response of tropical forests to global and regional anthropogenic change, hereafter anthropogenic change, is highly uncertain despite evidence marshaled elsewhere [1,3,4]. Here, I pose six questions to pinpoint sources of this uncertainty. First, are old-growth tropical forests...

INTRODUCTION the proper evaluation of the extracapsular extension (ECE), the invasion of seminal vesicles and regional lymph nodes are necessary to plan the treatment of localized prostate cancer. A model that assesses the risk of ECE in the specimen considering the clinical, histological and imaging findings is defined. MATERIAL AND METHODS prospective study in 85 patients with prostate canc...

Flash memory is a leading storage media with excellent features such as random access and high storage density. However, it also faces significant reliability and endurance challenges. In flash memory, the charge level in the cells can be easily increased, but removing charge requires an expensive erasure operation. In this thesis we study rewriting schemes that enable the data stored in a set ...

BACKGROUND The convectional strain-based algorithm has been widely utilized in clinical practice. It can only provide the information of relative information of tissue stiffness. However, the exact information of tissue stiffness should be valuable for clinical diagnosis and treatment. METHODS In this study we propose a reconstruction strategy to recover the mechanical properties of the tissu...

Indonesia is a country with very high population density, especially in some of the major metropolitan cities which can cause problems relating to limited land use. One these growth Jakarta, Tambora District, Kelurahan Jembatan Besi where this area has level density. Some areas district consist highly populated villages majority people depend on industrial works, convectional works their own ho...

In this article, we present an efficient way of implementing 90° phase shifter using Hilbert transformer with canonic signed digit (CSD) coefficients in FPGA. It is implemented using 27-tap symmetric finite impulse response (FIR) filter. Representing the filter coefficients by CSD eliminates the need for multipliers and the filter is implemented using shifters and adders/subtractors. The simula...

ABSTRACT: Radiofrequency ablation (RFA) is the most promising, extensively studied and widely applied technique in clinical practice for the local treatment of solid tumors, viz., liver, kidney, lung, bone, etc. However, the application of RFA in treatment of breast cancer Radiofrequency ablation (RFA) is the most promising, extensively studied and widely applied technique in clinical practice ...

A mathematical model predicting the oscillating motion in an oscillating heat pipe is developed. The model considers the vapor bubble as the gas spring for the oscillating motions including effects of operating temperature, non-linear vapor bulk modulus, and temperature difference between the evaporator and the condenser. Combining the oscillating motion predicted by the model, a mathematical m...
