In cognitive radio networks, spectrum sensing is used to detect the spectral state of authorized users. In particular, upon detecting primary users (PUs) appearances, Secondary User (SU) vacates the channel and performs the spectrum handoff. In order to protect the PUs, interference constrains and reserved channel are considered. If the SU can’t find any idle channel after the whole spectrum se...

Mycobacterium infection manifesting pyometra in postmenopausal women is a extremely rare disease that hardly responds to the usual treatment of pus drainage and antibiotics therapy. We present a case of a postmenopausal woman with pyometra caused by endometrial tuberculosis. Almost all of the pus could be drained through the stenotic cervical canal, with diffi cultly. The result of Pipelle endo...

This article presents the findings of the study where 173 English onomastic phraseological units (PUs) were classified according to their translations into Slovene. Four groups were identified. More than 61% of all PUs belongs to the group where the translation equivalent is either descriptive or represented by a one-word equivalent. This group is followed by two groups amounting to 18.50%, i.e...

was administered, and an incision made opposite the lower border of the pectoralis major muscle in the fold of the axilla; the skin superficial and deep fascias were divided, but no large vessel was injured. Then a director was forcibly pushed iuto the axilla for about an inch and a half, before the abscess was opened. After using a little force pus appeared ; a common dressing forceps was then...

This paper proposed a new Stackelberg game theoretic solution for joint power control and channel allocation in Cognitive Radio Networks (CRNs). The Primary Users (PUs) can admit Second Users (SUs) to access by pricing their interference power under the Interference Power Constraint (IPC). So, we formulate suitable revenue functions for SUs and PUs to manage the radio resource among users effic...

A young soldier was admitted to hospital late one night with it deep wound of the dorsum of his right hand, caused, he said, by a fall. (On subsequent questioning, the patient revealed that he had been involved in a fight, during the course of which he had struck his opponent in the mouth and received a bite.) The wound appeared clean at the time and was· therefore primarily sutured. The patien...

• Opportunistic spectrum access (OSA) in cognitive radio networks: using efficiently the radio frequency spectrum • Traditional static spectrum allocation to licensed primary users (PUs): severe inefficiencies, measurements indicate low spectrum utilization (under 30 %) • Dramatic demand surge for spectrum access by unlicensed secondary users (SUs), due to emerging technologies • OSA: dynamical...

In this paper, we study a cooperative cognitive radio network (CCRN) where the secondary user-transmitter (SU-Tx) assists bi-directional communication between a pair of primary users (PUs) following the principle of two-way relaying. In return, it gets access to the spectrum of the PUs to enable its own transmission to SU-receiver (SU-Rx). Further, in order to support sustainable operation of t...

A case of nocardiosis in a post-renal transplant patient is being reported for the first time from Eastern India. The patient had multiple abscesses on the right thigh and chest. Direct examination of the aspirated pus by Gram stain and modified Ziehl Neelsen stain revealed gram-positive beaded, partially acid-fast, branching filaments. Culture of the pus yielded Nocardia asteroides. The patien...
