We present two approaches for the localization of passive nodes in a communication network using ambient radio or sound signals. In our settings the communication nodes have unknown positions. They are synchronized but do not emit signals for localization and exchange only the time points when environmental signals are received. The signals occur at unknown positions and times, but can be disti...

discussion: the present case demonstrates that the uropathogenic e. hermanii clone can cause destruction of the kidneys. during asymptomatic bacteriuria or cystitis, the bacteria remain in the urinary tract. even when pyelonephritis develops, inflammatory response of the host is still restricted to the urinary tract. these signs mean that uropathogenic e. hermanii may be not very virulent. intr...

INTRODUCTION In contrast with Escherichia coli, the association of E. hermanii with urinary tract infections has not been described. CASE PRESENTATION In this case, E. hermanii was the sole isolate recovered from urine specimens of a pyelonephritis patient. The organism was found to be susceptible to piperacillin-tazobactam, ceftazidime, cefazolin, cefixime, aztreonam, gentamicin, tobramycin,...

Although feedback is considered to be an important factor in perceptual learning (PL), its role is normally considered limited to facilitation, rather than direct inducement, of PL. Recent studies, however, have suggested feedback to be more actively involved in the inducement of PL. The current study demonstrates an even more significant role for feedback in PL: feedback can evoke PL of a feat...

An elderly woman, distraught over the recent death of her husband, was found dead of an apparent suicide. Qualitative screening detected only the presence of diltiazem, an antihypertensive, antianginal agent that was prescribed for a known heart ailment. Quantitation of diltiazem was carried out on available fluids and tissues with the following results: blood 6.7 mg/L, urine 5.4 mg/L, vitreous...
