Published: October 2011

AbstractWe propose a new system of the multioptical tweezers array generation using dark‐bright soliton control within the multimicroring resonators and an add/drop filter.The dynamic tweezers are generated within an add/drop filter. By using the polarization mode identification, the entangle photon states of the tweezers can be formed, which is allowed to form the molecular quantum transmission. The number of tweezers within the add/drop filter can be tuned, amplified and quantum states of the molecule identified. The number of tweezers of 50–100 in an array with the smallest tweezer width of 2 nm is generated and achieved. We have also theoretically shown that the quantum multioptical tweezers can be controlled and tuned by varies the couple coefficient (κ) between 0.1 and 0.9, with ring resonator radii between 10 and 20 μm, which is available for molecule trapping and transportation in the communication uplink system via the add/drop filter. In application, the transmission of tweezers with different molecules or DNA or atom can be performed, which is available for high density molecular transportation via wireless communication system. © 2010 Wiley Periodicals, Inc.

Published: October 2011

AbstractCoherent detection for spectrally encoded optical labels is proposed and experimentally demonstrated for three label tones spectrally spaced at 1 GHz. The proposed method utilizes a frequency swept local oscillator in a coherent receiver supported by digital signal processing for improved flexibility and upgradeability while reducing label detection subsystem complexity as compared with the conventional optical autocorrelation based approaches. © 2010 Wiley Periodicals, Inc.

Published: October 2011

AbstractThis letter proposes a divide‐by‐3 frequency divider employing the linear mixer topology; the divider was fabricated in the 0.35‐μm CMOS 2P4M CMOS technology. The divider consists of an nMOS cross‐coupled LC oscillator and two injection MOSFETs in series with the cross‐coupled nMOSFETs. At the drain bias voltage of 1.2 V, the divider free‐running frequency is tunable from 3.73 to 3.92 GHz, and at the incident power of 0 dBm, the operational locking range is about 0.69 GHz, from the incident frequency 10.99 to 11.68 GHz. The core power consumption is 6.9 mW. The die area is 0.83 × 0.94 mm2. © 2010 Wiley Periodicals, Inc.

Authors: Li Jie , Hasan S. M. Rezaul 
Published: October 2011

AbstractThe design of a narrow‐band cascoded CMOS inductive source‐degenerated low noise amplifier (LNA) for 866 MHz UHF RFID reader is presented. Compared to other previously reported narrow‐band LNA designs, in this work the finite gds (= 1/r0) effect has been considered to improve the nanometric design, achieving simultaneous impedance and minimum Fmin noise matching at a very low power drain of 850 μW from a 0.7‐V supply voltage. The LNA was fabricated using the IBM 130 nm CMOS process delivering a power gain (S21) of ≈12 dB, a reverse isolation (S12) of ≈−34 dB, and an input power reflection (S11@866 MHz) of ≈−12 dB. It had a minimum pass‐band NF of around 2.2 dB and a 3rd order input referred intercept point (IIP3) of ≈−9.5 dBm. © 2010 Wiley Periodicals, Inc.

Ultra‐wideband antenna with on/off band‐notch control
Authors: Kelly James R. , Hall Peter S. , Gardner Peter 
Published: October 2011

AbstractThis article presents a band‐notched ultra‐wideband antenna having a pair of stop bands.These stop bands are located in close proximity on the frequency spectrum. Each stop band is created by a resonant element that is distinctly separate from the radiating part of the antenna. For these reasons, each of the stop bands can be turned on and off independently. The article demonstrates that this could be achieved using six microwave switches. The location of the two stop bands can also be controlled independently. © 2010 Wiley Periodicals, Inc.

Full‐wave simulation examining layout effect in CMOS RF amplifier design
Authors: Liu Yang , Lee Jeongeo , Choi Sungju , Kim Hyeongdong 
Published: October 2011

Abstractprocedure which examines the layout effect in a CMOS RF low noise amplifier design based on S‐parameters which are extracted using a full‐wave simulator HFSS is presented in this article.The S‐parameters of the circuit layout are successfully obtained at the bias condition by the proper use of the CMOS active and passive device models, avoiding the nonconvergence problem that exists in the simulator (Liang and Razavi, IEEE J Solid‐State Circuits 44 (2009)). The accuracy of the full‐wave simulation is verified by determining if the results between the circuit simulation and the simulation with the S‐parameters of the ideal connection lines (i.e., DC S‐parameters) of the circuit are the same, and its validity is demonstrated via a comparison of the simulated and measured results of a concurrent dual‐band LNA operating at 2.4 and 5.2 GHz in 180‐nm CMOS technology. © 2010 Wiley Periodicals, Inc.

Published: October 2011

AbstractThis article presents design considerations of a filter integrated Wilkinson power divider (FIPD), which helps to reduce the circuit size.The λ/4 impedance transformers of the conventional Wilkinson power divider are replaced by filters with an insertion phase of 90° at the center frequency. The concept is validated by two prototypes centered at 2.4 GHz. The measured 3‐dB bandwidths for both prototypes are 60% while for the conventional design is 200%. © 2010 Wiley Periodicals, Inc.

Improved miniaturization method for coupled‐line filters
Authors: Lee Seungku , Lee Yongshik 
Published: October 2011

AbstractA miniaturization method for coupled‐line filters is demonstrated that relies on the equality of the two most important parameters for filter synthesis, the propagation constant and the image impedance, before and after miniaturization.The method enables to maintain the bandwidth intact as opposed to the previous miniaturization method based on the same structure. This proves that bandwidth reduction in miniaturized filters is not due to miniaturization itself but rather due to the mathematical formulation of miniaturization. As compensation of reduced bandwidth is not necessary, the proposed method provides much simpler miniaturization procedure. © 2010 Wiley Periodicals, Inc.

Published: October 2011

AbstractPurposeTo investigate the association between constipation and the results of uroflowmetry with post‐void residual urine (PVR) tests in healthy children.Materials and MethodsWe enrolled healthy children aged between 4 and 12 years for evaluation of voiding and defecation function. A parent of children completed the questionnaire, and the children were asked to do uroflowmetry and PVR. Constipation is defined as defecation frequency ≤2 times/week or type 1–2 stool forms on Bristol stool scale. Uroflowmetry curve and PVR were eligible for analysis if voided volume was between 50 ml and expected capacity for age.ResultsTotally, 778 children (415 boys and 363 girls) with a mean age of 7.2 ± 2.2 years were eligible for analysis. The prevalence of constipation was 10.9% by low defecation frequency, and 28.4% by Bristol stool scale, respectively. Regarding the rate of constipation, there were no statistically significant differences between genders. Compared to children without low defecation frequency, constipated children had higher PVR (9.0 vs. 5.9 ml, P = 0.01), higher rate of PVR > 20 ml (17.7% vs. 7.1%, P = 0.01) and lower voiding efficiency (93.2% vs. 94.9%, P = 0.04). Compared to children without type 1–2 Bristol stool, constipated children did not have higher PVR (7.2 ml vs. 5.8 ml, P = 0.10), nor lower voiding efficiency (94.0% vs. 95.0%, P = 0.11). Urgency symptom score and rate of abnormal flow patterns were comparable between children with or without constipation.ConclusionConstipation defined as low defecation frequency was associated with incomplete bladder emptying in healthy children.

Published: October 2011

AbstractWiskott–Aldrich syndrome (WAS) and X‐linked thrombocytopenia (XLT) are caused by a mutation in the WAS gene on Xp11.22. We report two patients with IVS6+5G>A of WAS in a Korean family. The proband presented with classic WAS, whereas his maternal cousin had symptoms limited to XLT. Their mothers were proved to be carriers. The IVS6+5G>A mutation was reported to result in incomplete splicing of the donor site and typically associated with mild form of disease, XLT. Our observation of the intrafamilial variability of clinical manifestations of WAS further expands the genotype–phenotype correlations and suggests the presence of modifying genetic factors.

Authors: Levine Emmanuelle , Fréneaux Paul , Schleiermacher Gudrun , Brisse Hervé , Pannier Stéphanie , Teissier Natacha , Mesples Bettina , Orbach Daniel 
Published: October 2011

AbstractBackgroundInfantile myofibromatosis is characterized by proliferation of benign fibrous tumors arising in skin, subcutaneous tissue, muscle, or bone. Solitary and multicentric forms are described. Few reports are available in the pediatric population.ProcedureTo improve the knowledge of this rare tumor in infants, the authors present a series of all cases of infantile myofibromatosis treated in their institution over a 9‐year period in order to propose treatment guidelines based on their experience and a review of the literature.ResultsThe authors report a series of 9 cases, 8 solitary forms and 1 multicentric form with visceral involvement treated from 2000 to 2009. Median age was 10 months (range: 2 days–14 years). Six patients with solitary forms underwent primary surgical resection leading to remission. Only biopsy was performed in 1 case, followed by tumor regression with no recurrence. The last patient with a solitary form was treated by chemotherapy and then surgery allowing remission. The patient with a multicentric form presented complete regression of tumors after 1 year of vinblastine and methotrexate combination chemotherapy.ConclusionsInfantile myofibromatosis is a rare soft tissue tumor mainly concerning infants. Surgery is the treatment of choice for solitary forms when excision is possible. Close follow‐up may be proposed in the case of inoperable sites. In multicentric life‐threatening forms, chemotherapy promotes tumor regression and the vinblastine and methotrexate combination is effective with few long‐term adverse effects.

Pediatric venous thromboembolism in the United States: A tertiary care complication of chronic diseases
Authors: Setty Bhuvana A. , O'Brien Sarah H. , Kerlin Bryce A. 
Published: October 2011

AbstractBackgroundPediatric venous thromboembolism (VTE) is an increasingly common problem. We hypothesized that VTE occurs most commonly in tertiary care settings and that the pattern of associated illnesses may have changed from earlier reports.MethodsThe Kids' Inpatient Database 2006 was utilized to identify children ≤18 years old with in‐hospital VTE. Children were identified by the presence of thrombosis specific ICD‐9‐CM diagnosis or procedure codes. Remaining ICD‐9‐CM codes were utilized to categorize patients by acute or chronic illness. The incidence of in‐hospital VTE by hospital type, age, gender, race, and disposition were estimated.ResultsOver 4,500 children met the inclusion criteria (188/100,000 discharges). Most VTE discharges (67.5%) were from children's hospitals (RR 5.09; 95% CI 4.76; 5.44). Underlying chronic illnesses were associated with most VTE (76.2%), most commonly: cardiovascular (18.4%), malignancy (15.7%), and neuromuscular disease (9.9%). VTE not associated with chronic illness were most often idiopathic (12.6%), followed by infections (9.5%), and trauma (9.1%). The greatest proportions of children with VTE were infants (23.1%) and adolescents (37.8%). However, when standardized against the entire database of discharges, infants were least likely to develop VTE (RR 0.48; 95% CI 0.43; 0.52), while adolescents were at highest risk (RR 1.89; 95% CI 1.73; 2.07). Hospitalizations ending with death were more likely to include VTE (RR 6.16; 95% CI 5.32; 7.13).ConclusionsPediatric VTE is most commonly seen in tertiary care. Adolescents are at greatest risk to develop in‐hospital VTE. Patients whose hospitalization ended with death are at much greater risk to develop VTE.

Published: October 2011

ObjectiveTo determine the performance of screening for late pre‐eclampsia (PE) by maternal characteristics, uterine artery Doppler and a set of biochemical markers at 11 + 0 to 13 + 6 weeks' gestation.MethodsProspectively enrolled women at 11 + 0 to 13 + 6 weeks. Maternal characteristics, highest UtA pulsatility index and serum placental biomarkers including pregnancy‐associated plasma protein‐A, placental growth factor, soluble fms‐like tyrosine kinase 1, P‐selectin and neutrophil gelatinase‐associated lipocalin were recorded.ResultsThe rate of PE was 2.5% (13/528). Four (0.8%) had severe PE. A combined screening model that included placental growth factor, soluble fms‐like tyrosine kinase 1 and neutrophil gelatinase‐associated lipocalin could detect 77% of PE at a 10% false‐positive rate. Mean risk for mild PE was 8.8% ± 6.4, mean risk for severe PE was 38.6% ± 4.3. Mean risk for controls was 2% ± 4.1.ConclusionThis combination of maternal biochemical variables in the first trimester can detect a consistent number of late PE. Further studies on a new and independent series of data could confirm the presented results. Copyright © 2011 John Wiley & Sons, Ltd.

ObjectiveTo assess the feasibility of offering array‐based comparative genomic hybridization testing for prenatal diagnosis as a first‐line test, a prospective study was performed, comparing the results achieved from array comparative genomic hybridization (aCGH) with those obtained from conventional karyotype.MethodWomen undergoing amniocentesis or chorionic villus sampling were offered aCGH analysis. A total of 1037 prenatal samples were processed in parallel using both aCGH and G‐banding for standard karyotyping. Specimen types included amniotic fluid (89.0%), chorionic villus sampling (9.5%) and cultured amniocytes (1.5%).ResultsChromosomal abnormalities were identified in 34 (3.3%) samples; in 9 out of 34 cases (26.5%) aCGH detected pathogenic copy number variations that would not have been found if only a standard karyotype had been performed. aCGH was also able to detect chromosomal mosaicism at as low as a 10% level. There was complete concordance between the conventional karyotyping and aCGH results, except for 2 cases that were only correctly diagnosed by aCGH.ConclusionsThis study demonstrates that aCGH represents an improved diagnostic tool for prenatal detection of chromosomal abnormalities. Although larger studies are needed, our results provide further evidence on the feasibility of introducing aCGH as a first‐line diagnostic test in routine prenatal diagnosis practice.

A new sequence isomer of AB‐polybenzimidazole for high‐temperature PEM fuel cells
Authors: Gulledge Alexander L. , Gu Bin , Benicewicz Brian C. 
Published: October 2011

AbstractA new sequence isomer of AB‐polybenzimidazole (AB‐PBI) was developed as a candidate for high‐temperature polymer electrolyte membrane fuel cells. A diacid monomer, 2,2′‐bisbenzimidazole‐5,5′‐dicarboxylic acid, was synthesized and polymerized with 3,3′,4,4′‐tetraaminobiphenyl to prepare a polymer that was composed of repeating 2,5‐benzimidazole units. In contrast to previously prepared AB‐PBI, which contains only head‐to‐tail benzimidazole sequences, the new polymer also contains head‐to‐head and tail‐to‐tail benzimidazole sequences. The polymer was prepared in polyphosphoric acid (PPA) and cast into membranes using the sol–gel PPA process. Membranes formed from the new AB‐PBI were found to be mechanically stronger, possessed higher acid doping levels, and showed improved fuel cell performance, when compared to the previously known AB‐PBI. © 2011 Wiley Periodicals, Inc.

The effects of dopant acids on structure and properties of poly(o‐methoxyaniline)
Authors: Wang Xiao , Ray Sudip , Gizdavic‐Nikolaidis Marija , Easteal Allan J. 
Published: October 2011

AbstractPoly(o‐methoxyaniline) (POMA) was chemically synthesized using ammonium persulfate (APS) as oxidant. Methane sulfonic acid (MSA), hydrochloric acid (HCl), and p‐toluene sulfonic acid (pTSA) were used as dopants, under the same reaction conditions. For comparison, undoped POMA was also synthesized. The polymer samples were characterized by Fourier transform infrared spectroscopy (FTIR), four‐probe conductivity measurement, scanning electron microscopy (SEM), electron spin resonance (ESR), gel permeation chromatography (GPC), and determination of specific surface area. The antioxidant activities of POMA were assessed via reaction with 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) free radical, and the anti‐microbial activities were determined as minimum bactericidal concentrations against E. coli 25422 and S. aureus 6838. When doped with relatively strong acids, high yield (above 84%) was achieved, compared to the relatively low yield (45%) when no dopant was present. The conductivity decreased in the order POMA‐pTSA > POMA‐HCl > POMA‐MSA > undoped POMA. A polaron conduction mechanism was supported by FTIR and ESR spectra. The morphology of the polymers was found to be effectively controlled by dopants. All POMA polymers showed strong free radical scavenging ability, which was highly correlated with the specific surface areas of the polymer particles. All the tested samples showed activity against S. aureus 6838, but not at the concentrations tested against E. coli 25422. © 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2012
