Published: September 2008

AbstractThis letter presents a monopole type penta‐band internal antenna using a parasitic element. The proposed antenna, with the small size of 37 × 8 × 3.5 mm3 can provide sufficient bandwidth to cover the GSM(850/900), DCS, PCS, and WCDMA bands. The measured impedance bandwidth (VSWR ≤ 3) of the proposed antenna can cover 250 MHz in the lower frequency band and 1082 MHz in the upper frequency band. Ansoft HFSS (High Frequency Structure Simulator) is employed to analyze the proposed antenna in the design process and to compare it with the experimental results. The measured peak gains of the proposed antenna range from 1.21 to 2.48 dBi for the GSM(850/900), DCS, PCS, and WCDMA bands. © 2008 Wiley Periodicals, Inc.

Third and fourth Stokes parameters in polarimetric passive microwave remote sensing of rough surfaces over layered media
Authors: Tsang Leung , Xu Peng , Chen Kun Shan 
Published: September 2008

AbstractWe consider the four Stokes parameters in microwave emission from a layered medium with the top interface being a rough surface. The rough surface varies in one horizontal direction so that azimuthal asymmetry exists in the 3‐D problem. Dyadic Green's functions of multilayered media are used to formulate the surface integral equations. Periodic boundary conditions are used. The numerical results show that the presence of the layered media below the rough surface reduces the vertical and horizontal brightness temperatures. The interaction between the rough surface and the layered media also enhance the third and fourth Stokes parameters. In particular, the fourth Stokes parameter can be large for such geometrical configurations. Results show that the nonzero third and fourth Stokes parameters exist for all frequencies and are particularly large when the rough surface has large slope. © 2008 Wiley Periodicals, Inc.

Published: September 2008

AbstractA semiconductor optical amplifier fiber ring laser (SOAFRL) utilizing a Fiber Bragg Grating (FBG) is demonstrated. The laser operates at a wavelength of 1547.64 nm, equal to the Bragg wavelength. By removing FBG, the SOAFRL shows a multi‐modes output due to the resonant characteristics of the semiconductor optical amplifiers (SOA's) gain. The output power ripple is observed around 5 dB. The experimental results show that when the saturation level is reached, the SOAFRL with the FBG shows a higher saturation current and peak power compared to that of the SOAFRL without the FBG. Mode competition in the cavity for the free‐running ring SOAFRL results in a lower peak power as well as a broader bandwidth as the current is increased. By incorporating the FBG in the SOAFRL, a lasing wavelength is generated and as such the side mode suppression ratio (SMSR) of the laser is significantly improved, resulting in a higher peak power at higher bias currents. © 2008 Wiley Periodicals, Inc.

AbstractAn X‐band miniaturized antenna which uses half‐mode substrate integrated waveguide structure is designed. We analyzed the electromagnetic field using the cavity model and the electromotive force method. The input impedance, simulated and experimental results of return loss, resonant frequency, and radiation patterns are presented. Its performances are as same as those of the corresponding microstrip antenna, but its size is half of the microstrip antenna. This planar structure can be integrated on the same substrate with other components such as filter and amplifier, and it can also be used to easily form antenna arrays. © 2008 Wiley Periodicals, Inc.

AbstractA low‐cost homodyne Doppler radar system with 24.128 GHz phase lock loop (PLL) frequency synthesizer has been designed, fabricated, and applied in remote detection of heart beat. In this direct conversion Doppler radar system, the PLL frequency synthesizer is utilized as a high‐stability local oscillator which is realized traditionally by voltage control oscillator (VCO). This fourth‐order topology PLL‐frequency synthesizer with 8 dBm output power and‐67 dBc/Hz at 1 kHz phase noise offset the carrier can improve the radar system velocity precision drastically.

Published: September 2008

AbstractIn this study, a multimodulus CMOS injection‐locked frequency divider (ILFD) fabricated in a 0.18‐μm CMOS process is designed and the operation principle of the ILFD is described, which was realized using a cross‐coupled PMOS LC‐tank oscillator as the load of a double‐balanced NMOS Gilbert mixer. The stacked structure allows entire mixer current to be reused by the VCO cross‐coupled pair. At the supply voltage of 1.8 V, the free‐running frequency is from 2.31 to 2.65 GHz. Division ratio of 2, 3, 4, and 6 can be found in the ILFD function, and the ILFD can also function as a first‐harmonic injection‐locked oscillator. At the incident power of 0 dBm, the locking range in the ÷2 mode is from the incident frequency 3.4 to 6.4 GHz. © 2008 Wiley Periodicals, Inc.

Published: September 2008

AbstractA compensation technique to generate enhanced return loss and directivity is proposed by using additional branch lines for a broadside coupler. The branch lines at all ports are added to reduce the port impedance, resulting in improvement of impedance matching for the tight coupled broadside coupler. The measured results of the proposed low‐temperature cofired ceramic (LTCC) coupler show more than 4 dB enhancements of return loss and isolation, compared with those of the conventional one. © 2008 Wiley Periodicals, Inc.

AbstractFive hundred thirteen soft tissue tumours of childhood referred to the International Society of Pediatric Oncology (SIOP) Rhabdomyosarcoma study have been reviewed. The period covered was from January 1975 to December 1983. Three hundred thirty‐nine neoplasms were regarded as embryonal rhabdomyosarcoma. The histological diagnosis of all referred tumours is given, and a classification of rhabdomyosarcomas developed during the course of the study is described. The relationship between histological subtypes and aspects of clinical behaviour is presented. The classification is thought to be helpful in diagnosis and also in assessment of the likelihood of recurrence and/or metastasis of childhood rhabdomyosarcoma.

Published: September 2008

AbstractAllograft inflammatory factor‐1 (AIF‐1) is a cytokine that plays a major role in the immune response and proliferative vasculopathy that occur during chronic allograft rejection. The purpose of this study was to characterize the cellular expression pattern and pathogenetic role of AIF‐1 in nerve biopsies from patients with vasculitic neuropathy. We performed immunohistochemistry in human nerve biopsies of 10 patients with vasculitic neuropathies (VASs), 6 with chronic inflammatory demyelinating polyneuropathies (CIDPs), 5 with noninflammatory axonal neuropathies (NIANs), and 3 control nerves (CNs). In the CIDP and VAS nerves, AIF‐1 expression was higher than in CN and NIAN nerves (P < 0.05). AIF‐1 was increased in the arterial walls of VAS compared with CIDP nerves (P < 0.05). Vascular smooth muscle cells in vasculitic nerve express AIF‐1 at a higher level compared with CIDP and NIAN. AIF‐1 plays a role in inflammatory nerve disease and vascular smooth muscle cell proliferation and may be a new molecular target for treatment. Muscle Nerve 38: 1272–1279, 2008
Long‐term intensive electrically stimulated cycling by spinal cord–injured people: Effect on muscle properties and their relation to power output

Published: September 2008

AbstractInactivity and muscular adaptations following spinal cord injury (SCI) result in secondary complications such as cardiovascular disease, obesity, and pressure sores. Functional electrically stimulated (FES) cycling can potentially reduce these complications, but previous studies have provided inconsistent results. We studied the effect of intensive long‐term FES cycle training on muscle properties in 11 SCI subjects (mean ± SEM: 41.8 ± 2.3 years) who had trained for up to 1 hour/day, 5 days/week, for 1 year. Comparative measurements were made in 10 able‐bodied (AB) subjects. Quadriceps maximal electrically stimulated torque increased fivefold (n = 5), but remained lower than in AB individuals. Relative force response at 1 HZ decreased, relaxation rate remained unchanged, and fatigue resistance improved significantly. Power output (PO) improved to a lesser extent than quadriceps torque and not to a greater extent than has been reported previously. We need to understand the factors that limit PO in order to maximize the benefits of FES cycling. Muscle Nerve 38: 1304–1311, 2008

Published: September 2008

AbstractEvidence suggests that sensory loss may occur in a proportion of patients affected by poliomyelitis. We hypothesize that sensory problems may be a lasting sequela in some polio survivors. Sensory pathways in polio survivors were evaluated clinically and electrophysiologically using sensory evoked potentials (SEPs). Patients with sensory deficits or abnormal SEPs were further evaluated by magnetic resonance imaging (MRI). Twenty‐two patients were studied. The mean age was 64.7 years (age range: 56–81 years). Clinically, sensory impairments were found in 4 patients. Upper limb SEPs were normal. Lower limb SEPs were abnormal in 10 patients. In 1 patient, clinical and electrographic findings correlated with a patch of atrophy in the spinal cord, as shown by MRI. Sensory derangements may be found in a proportion of aging polio survivors. SEP studies may add sensitivity when evaluating sensory function in this cohort. It remains unclear whether these sensory abnormalities are related to remote poliomyelitis. Further studies are necessary. Muscle Nerve 38: 1266–1271, 2008
Comparison of parametric and nonparametric reference data in motor unit potential analysis
Authors: Podnar Simon 
Published: September 2008

AbstractFor calculation of outlier reference intervals, by definition nonparametric statistics are applied, while for mean value reference intervals parametric or nonparametric statistics can be used. The aim of this study was to compare the mean value reference intervals and their sensitivity for diagnosis of myopathy. Quantitative concentric needle electromyography (EMG) of the biceps brachii muscle was performed using multi–motor unit potential (MUP) analysis. In 34 healthy subjects both parametric (mean ± 2SD) and nonparametric (2.5th–97.5th percentiles) reference intervals were calculated for mean values of MUP parameters, while for outliers nonparametric reference intervals (5th–95th percentiles) were calculated. Their sensitivity was tested in 29 patients with facioscapulohumeral muscular dystrophy. Nonparametric reference intervals were narrower than parametric intervals, which resulted in slightly higher sensitivities when combined with outlier limits (e.g., thickness = 86% and 83%, respectively).

Collateral reinnervation by the superior laryngeal nerve after recurrent laryngeal nerve injury
Authors: Hydman Jonas , Mattsson Per 
Published: September 2008

AbstractThis study investigates the role of the intact superior laryngeal nerve (SLN) in the reinnervation process of one of the laryngeal muscles, the posterior cricoarytenoid muscle (PCA), following recurrent laryngeal nerve (RLN) injury. Using a chronic RLN injury model in the adult rat, PCA reinnervation was assessed by retrograde double‐tracing techniques in combination with electrophysiology and immunohistochemistry of muscle sections. The results demonstrate that the PCA receives dual innervation from both laryngeal nerves even in the uninjured system. Functionally significant collateral reinnervation originates from intact SLN fibers following RLN injury, mainly due to intramuscular sprouting rather than by recruitment of more motor neurons. This may be important when choosing surgical and/or medical treatment for patients with RLN injury. Muscle Nerve 38: 1280–1289, 2008
A generic model of motor‐carrier fuel optimization
Authors: Suzuki Yoshinori 
Published: September 2008

AbstractFuel optimizers are decision models (software products) that are increasingly recognized as effective fuel management tools by U.S. truckload carriers. Using the latest price data of every truck stop, these models calculate the optimal fueling schedule for each route that indicates: (i) which truck stop(s) to use, and (ii) how much fuel to buy at the chosen truck stop(s) to minimize the refueling cost. In the current form, however, these models minimize only the fuel cost, and ignore or underestimate other costs that are affected by the models' decision variables. On the basis of the interviews with carrier managers, truck drivers, and fuel‐optimizer vendors, this article proposes a comprehensive model of motor‐carrier fuel optimization that considers all of the costs that are affected by the model's decision variables. Simulation results imply that the proposed model not only attains lower vehicle operating costs than the commercial fuel optimizers, but also gives solutions that are more desirable from the drivers' viewpoint. © 2008 Wiley Periodicals, Inc.

Published: September 2008

AbstractA non‐experimental longitudinal prospective study was conducted to examine the relationships between patient‐centered nursing interventions (PCNIs), system characteristics, patient characteristics, and desired health outcomes (DHOs) for 173 hematology‐oncology patients. Forty‐nine nurse participants provided system characteristics data. Confirmatory factor analyses yielded parsimonious scales to operationalize the variables. In the path model, one PCNI—individualization—was positively related to three subsequent DHOs: authentic self‐representation, optimism, and sense of well‐being. Two additional PCNIs—responsiveness and proficiency—were positively related to subsequent trust in nurses. PCNIs did not vary with patient race, ethnicity, age, gender, or educational level. Patient‐centeredness of care for cancer patients may be enhanced by quality improvement activities that measure and monitor these PCNIs and resultant outcomes. © 2008 Wiley Periodicals, Inc.
