It is proved in [l] that if a tree T of order n is not a star, then there exists an edgedisjoint placement of two copies of this tree into its fourth power. In this paper, we prove the packing of some trees into their third power. @ 2003 Eisevier Ltd. Ali rights reserved. Keywords-Embedding, Packing, Permutation, Placement, Power tree.

A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...

A 2.4-GHz single-stage CMOS low noise amplifier (LNA) structure with ultra low power consumption is proposed. A current reuse technique is used to decrease power dissipation with increasing amplifier transconductance for the LNA. Thus, the same amplifier transconductance for the LNA will be achieved at decreased power dissipation. Also, due to the use of an inverter-type amplifier which has a s...

This paper presents a novel sigma-delta modulator architecture dedicated to very low-power applications wherein third-order noise shaping is achieved with very modest constraints on the analog part. The architecture is based on an enhanced MASH structure where the feedback of every loop is the sum of its output and of the output of the following loops. The analytical model of the architecture i...

OBJECTIVE To determine if compensatory actions take place at the pelvis and other joints of the affected lower limb in subjects who were in an early stage of hip osteoarthritis (OA). DESIGN Nonrandomized, case-control study. SETTING A gait laboratory. PARTICIPANTS Seventeen patients with OA of the hip (clinical group) matched with 17 healthy elderly subjects (nonclinical group). INTERVE...

Conflict management is one of the primary requirements for social complexity. Of the many forms of conflict management, one of the rarest and most interesting is third-party policing, or intervening impartially to control conflict. Third-party policing should be hard to evolve because policers personally pay a cost for intervening, while the benefits are diffused over the whole group. In this s...

Short Abstract—A simplified inverse class F power amplifier (PA) with a voltage second harmonic peaking and third harmonic short operating at 2.14GHz for WCDMA base station applications has been developed. The load network is based on transmission line harmonic traps and provides high impedance at the second and low impedance at the third harmonic to the PA. The PA uses a packaged Silicon LDMOS...

We demonstrated the power noise reduction of a continuous-wave laser field by means of an effective third-order Kerr nonlinear cavity. In contrast to conventional noise reduction schemes relying on linear cavities, a strong noise suppression at Fourier frequencies below the linewidth of the nonlinear cavity was possible. The laser light was reflected off a Kerr nonlinear cavity that had a half ...

—This paper presents the design of a highly linear broadband power amplifier (PA) operating from 200MHz to 3GHz for Long Term Evolution (LTE) pico-cell base station. The monolithic microwave integrated circuit (MMIC) PA is realized with 0.25-μm Enhancement Mode Pseudomorphic High Electron Mobility Transistor (E-pHEMT) process. The broadband PA employs a novel dual feedback technique to achieve...
