As wireless sensor networks are constituted of nodes with limited life batteries, energy efficiency is a very important metric at all levels of system design. Therefore, performing optimal modulation schemes is a crucial task at the physical layer of this class of networks. This paper investigates the best modulation strategy to minimize the total energy consumption required to send a given num...

Resveratrol (3,4',5-trihydroxy-trans-stilbene), a naturally occurring polyphenolic compound found abundantly in grape skins and red wines, has been found to pharmacologically precondition the heart against ischemia reperfusion injury through the potentiation of a survival signal involving cAMP response element-binding protein-dependent phosphatidylinositol 3-kinase-Akt-BclII pathway. The presen...

Sir, Regarding the letter, we thank Dr. Gambaro et al. for the interest in our recent paper published in Nephrology Dialysis Transplantation. We agree with the observation that the majority of patients with medullary sponge kidney (MSK) do not present the typical distal renal tubular acidosis (dRTA) clinical phenotype (e.g. growth failure from infancy). However, dRTA is characterized by a wide ...

Musculoskeletal (MSK) complaints are common within primary care (1) (2) (3) but some General Practitioners (GPs)/family physicians do not feel comfortable managing these symptoms (3), preferring to refer onto hospital specialists or Integrated Clinical Assessment and Treatment Services (ICATs). Long waiting times for hospital outpatient reviews are a major cause of patient inconvenience and com...

We consider the design of convolutional codes and low-density parity-check (LDPC) codes with minimum-shift keying (MSK) when the receiver employs iterative decoding and demodulation. The main idea proposed is the design of coded schemes that are well matched to the iterative decoding algorithm being used rather than to hypothetical maximum-likelihood decoding. We first show that the design is c...

We suggest two algorithms that allow e cient timing recovery for MSK based on the computation of the Fourier spectrum of the absolute value of the di erential phases. One is suited for parallel frequency estimation while the second is less complex but requires previous frequency correction. The algorithms are investigated using both analysis and simulation. The two algorithms approximately lead...

We investigate a novel nondata-aided method for jointly estimating timing and carrier frequency offset in MSKtype modulation. The algorithm has a feedforward structure and lends itself to a simple digital implementation. Its estimation accuracy depends on a design parameter that may be varied to trade performance for computational complexity. Setting the parameter to unity yields a synchronizat...
