Local Flooding Phenomena in Channel and Land Areas Occurring during Dynamic Operation of a PEFC
Authors: von Dahlen S. , Schneider I. A. 
Published: November 2012

AbstractIn this work, we report on flooding phenomena occurring during dynamic operation of a polymer electrolyte fuel cell (PEFC). The combination of high spatially and temporally resolved neutron radiography and submillimeter resolved current density distribution measurements enables the simultaneous observation of local liquid water content and current density transients in the channel and land areas of a differentially operated PEFC air cathode. The local transients of a triangular voltage sweep and a voltage step are presented here. Both results demonstrate that in the land area the current density is only marginally affected by the local liquid water content. In the voltage sweep experiment, at higher cell polarization a limiting current density is observed in the land area as a result of mass transport limitations due to the high lateral diffusion path length. In the channel area the corresponding transients of the liquid water content and the current density both exhibit a hysteresis. The transients of the voltage step indicate liquid water rearrangement in channel and land areas as a slow process occurring on a time scale of several minutes. Thereby, the local cell performance is primarily affected by the local liquid water content in front of the oxygen electrode.

AbstractAngioimmunoblastic T‐cell lymphoma (AITL) is characterized by an aggressive clinical course and unfavourable prognosis. Refractory AITL patients have very few treatment options. Lenalidomide has previously been reported to have clinical efficacy in this setting; however, long‐term reports are limited. A 59‐year‐old man was referred to the hospital with fatigue, skin rash, weight loss and generalized lymphadenopathy and was diagnosed with AITL; clinical stage was IV B with bone marrow involvement. The patient had an unsatisfactory response despite three lines of conventional chemotherapy and radiotherapy. The patient received lenalidomide monotherapy (25 mg once daily) on days 1 to 21 of every 28‐day cycle for six cycles, followed by maintenance therapy with six cycles of lenalidomide 15 mg once daily on days 1 to 21 of every 28‐day cycle. A computed tomography scan was assessed before lenalidomide treatment, after the third cycle, at disease restaging 2 months after completion of the induction phase, every 3 months during the maintenance phase and every 6 months during the follow‐up period. At the last evaluation, after a follow‐up of 30 months, the patient maintained a clinical and radiological complete response. The treatment was well tolerated with manageable toxicity. Lenalidomide treatment demonstrated for the first time in the literature impressive and long‐term clinical efficacy in a heavily pretreated chemorefractory AITL patient.

ABSTRACTSupplementary irrigation is an efficient strategy for improving yield and water use efficiency in rainfed agriculture. However, water allocation is a challenge because water resources are restricted. Therefore, water allocation management between irrigated and rainfed fields could be a viable strategy. Water resources for supplementary irrigation in rainfed fields are saved through deficit irrigation in irrigated lands. In this study, water allocation between irrigated and rainfed fields was optimized to maximize total economic income in Kermanshah and Lorestan provinces. Results showed that total income from grains and legumes increased by 443 000 and 397 000 million rials‡ in Kermanshah and Lorestan provinces, respectively. When saved water is applied used for supplementary irrigation only on grain rainfed fields, total income increased by 8.3 and 16.3%. When saved water was transported in between provinces and applied on rainfed fields, total income increased by 14.3% in both provinces. When transported water was applied as supplementary irrigation only on rainfed grain fields, total income increased by 11.3% in both provinces compared to the current situation.

Authors: Theisen‐Toupal Jesse , Horowitz Gary L. , Breu Anthony C. 
Published: November 2012

BACKGROUNDSerum folate levels are commonly ordered for multiple indications in the inpatient and emergency department settings. Since mandatory folic acid fortification in 1998, there has been a decreasing prevalence of folate deficiency in the United States.OBJECTIVEOur objective was to determine the indications, rate of deficiency, charge and cost per deficient result, and change in management per deficient result in serum folate testing in inpatients and emergency department patients.DESIGNRetrospective analysis of all inpatient and emergency department serum folate tests.METHODSWe analyzed all inpatient and emergency department serum folate tests performed over a 12‐month period. We reviewed the charts of 250 patients and all low‐normal or deficient serum folate levels to determine indications, comorbidities, and change in management based on result. Charge and cost analyses were performed.SETTING/PATIENTSAll inpatient and emergency department patients with a serum folate test performed at a major medical center in Boston, Massachusetts.RESULTSA total of 2093 serum folate tests were performed in 1944 patients with 2 deficient levels. The most common indications were anemia without macrocytosis and anemia with macrocytosis. The amount charged per deficient result was $158,022. The cost to the hospital per deficient result was less than $2093.CONCLUSIONSIn folic acid fortified countries, serum folate testing has low utility and poor cost effectiveness for all indications in inpatients and emergency department patients.

Published: November 2012

BACKGROUNDPerson‐job fit is an organizational construct shown to impact the entry, performance, and retention of workers. Even as a growing number of physicians work under employed situations, little is known about how physicians select, develop, and perform in organizational settings.OBJECTIVEOur objective was to validate in the hospitalist physician workforce features of person‐job fit observed in workers of other industries.DESIGNThe design was a secondary survey data analysis from a national stratified sample of practicing US hospitalists.MEASURESThe measures were person‐job fit; likelihood of leaving practice or reducing workload; organizational climate; relationships with colleagues, staff, and patients; participation in suboptimal patient care activities.RESULTSResponses to the Hospital Medicine Physician Worklife Survey by 816 (sample response rate 26%) practicing hospitalists were analyzed. Job attrition and reselection improved job fit among hospitalists entering the job market. Better job fit was achieved through hospitalists engaging a variety of personal skills and abilities in their jobs. Job fit increased with time together with socialization and internalization of organizational values. Hospitalists with higher job fit felt they performed better in their jobs.CONCLUSIONSFeatures of person‐job fit for hospitalists conformed to what have been observed in nonphysician workforces. Person‐job fit may be a useful complementary survey measure related to job satisfaction but with a greater focus on function.

Published: November 2012

AbstractThe liquid‐phase esterification of acetic acid and isoamyl alcohol has been studied to develop a kinetic model using a sequential experimental design based on the divergence criterion. Data come from batch reactor experiments, performed in the temperature range of 316–363 K. Discrimination among 36 possible kinetic models, written in terms of activity, mole fractions, and molar densities, is possible through the deviance information criterion, as estimated by a Markov chain Monte Carlo technique. The obtained results indicate a negligible heat of reaction and a clear autocatalytic effect of acetic acid on the esterification rate. © 2012 Wiley Periodicals, Inc. Int J Chem Kinet 45: 10–18, 2013

Authors: Park Jin‐Woo , Kwon Bum Sun , Chang Ji Hae , Sim Kyoung Bo 
Published: November 2012

AbstractObjectives/Hypothesis:Nasal backflow is the regurgitation of material into nasopharynx during swallowing and it can be easily observed by videofluoroscopy. We aimed to evaluate the association between nasal backflow and the prevalence of aspiration, as well as the relationship between nasal backflow and the opening of the upper esophageal sphincter.Study Design:Retrospective case‐control study.Methods:There were 182 cases of videofluoroscopic swallowing studies that were retrospectively reviewed. The presence of nasal backflow and laryngeal aspirations were checked, and the anteroposterior maximum width of the upper esophageal sphincter opening was measured on lateral images of videofluoroscopic swallowing studies. The difference in maximum upper esophageal sphincter width between the group with nasal backflow and the group without nasal backflow was statistically verified.Results:Twenty patients showed nasal backflow, which was closely related to laryngeal aspiration (odds ratio = 10.97; 95% CI = 2.46–48.85; P < 0.05). Their maximal upper esophageal sphincter width (mean ± standard deviation) was 6.82 ± 1.96 mm and significantly different from the group without nasal backflow (9.35 ± 1.56 mm) (P < 0.05).Conclusion:Nasal backflow was closely associated with the presence of aspiration; the opening of upper esophageal sphincters significantly decreased in the cases of nasal backflow.

Published: November 2012

Objectives/HypothesisSeveral genes have been reported to be upregulated in human nasal polyps in previous genetic analyses. Among these genes, periostin is known to be overexpressed in nasal polyps obtained from aspirin‐sensitive patients. Using periostin‐null mice, we investigated the role of periostin in a murine model of eosinophilic rhinosinusitis with nasal polyps.Study DesignAnimal study.MethodsEosinophilic rhinosinusitis was induced in both periostin‐null and wild‐type mice according to previously established protocols. In brief, ovalbumin (OVA) was used for sensitization and prolonged intranasal stimulation. Staphylococcus aureus enterotoxin B was applied intranasally to develop polyplike lesions. To examine the inflammation and mucosal lesions, hematoxylin and eosin, Sirius red, and Giemsa staining were performed.ResultsThere was no definite difference in the maximal mucosal thickness between periostin‐null and wild‐type mice. In contrast, some parameters of inflammation, including the number of polyplike lesions and mast cells, were aggravated in the periostin‐null mice compared to wild type. Eosinophilic infiltration was aggravated in the OVA‐stimulated periostin‐null mice, compared to OVA‐stimulated wild‐type mice, whereas there was no apparent difference between wild‐type and periostin‐null mice challenged with additional S aureus enterotoxin B.ConclusionsThe loss of periostin appears to enhance polyplike lesion formation and mast cell infiltration in a mouse model of eosinophilic rhinosinusitis with nasal polyps.

AbstractBand diagrams of 2D arrays of dielectric rods are simulated at TE wave incidence in dependence on dielectric permittivity of rod material. It is shown that permittivity defines the variety of propagation modes corresponding to extreme energies of the lowest transmission bands because of interplay between Bragg and Mie resonances. © 2012 Wiley Periodicals, Inc.

A 21.68 GHz low‐power frequency synthesizer chip design with an injection‐locked frequency divider
Authors: Huang Jhin‐Fang , Hsu Chien‐Ming , Chen Kuo‐Lung , Liu Ron‐Yi 
Published: November 2012

AbstractA 21.68 GHz low‐power frequency synthesizer with a LC‐tank voltage‐controlled oscillator (VCO) is implemented in TSMC 90 nm CMOS process.In this proposed circuit, there are three important features. The primary advantage of this circuit is the use of an all‐NMOS cross‐coupled Colpitts VCO, which decreases transistor parasitic capacitances and reduces phase noise. Second, an injection‐locked frequency divider (ILFD) is utilized in the first divider stage to divide the high frequency signal. Third, a low supply voltage of 1.2 V is used to reduce power consumption. Measured results achieve that the locked output frequency is tunable from 21.54–21.96 GHz and the phase noise is about −97.47 dBc/Hz at 1 MHz offset from 21.68 GHz. The mixed output power spectrum at ILFD output frequency of 10.22 GHz is −2.97 dBm and the overall power consumption is 9.24 mW. Including pads, the chip area is 0.8 (0.8 × 1.0) mm2. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:200–205, 2013; View this article online at wileyonlinelibrary.com.

Published: November 2012

AbstractThe ground plane of a handset device plays an important role in the radiation process. As a consequence, through a ground plane modification, it is possible to obtain a multiband performance while keeping small antenna dimensions. Numerical simulation using Method of Moments has been used to understand the effect of the slots and a prototype has been built to validate the solution. The proposal consists in a multiband planar monopole handset antenna featuring a small area of 13 mm × 11 mm with a slotted ground plane operating in multiple communication standards (GSM850, GSM900, DCS, PCS, UMTS, LTE2300, WiMAX, Bluetooth, and Wi‐Fi). Thanks to the presence of the slots, the bandwidth and efficiency results have been significantly improved. © 2012 Wiley Periodicals, Inc.

Transmission of 100 GHz w‐band frequency MIMO‐OFDM signals with 90 Gbps downstream and 30 Gbps upstream using radio over fiber system
Authors: Fang Wei Jin , Huang Xu Guang , Yang Kai , Zhang Xiao Min 
Published: November 2012

AbstractIn this article, we propose and demonstrate an orthogonal frequency division multiplexing‐radio over fiber (OFDM‐ROF) system based on three channels sextupling‐frequency scheme using an external modulation of a distributed feedback laser diode (DFB‐LD) and dual drive Mach–Zehnder modulator (DD‐MZM) for carrying 100 GHz W‐band frequency multiple‐input multiple‐output (MIMO)‐OFDM signals with 90 Gbps downstream. MIMO‐OFDM algorithms effectively compensate for impairments in the wireless link. Without using costly W‐band components, a transmission system with 50 km single mode fiber (SMF) and 4 m wireless transmission operation at 100 GHz is experimentally validated. The power penalties for MIMO‐OFDM signals of base stations are less than 3 dBm. For the upstream transmission, wavelength reuse with 30 Gbps 4QAM upstream signals is experimentally demonstrated. The minimum optical spectral gap between residue downstream OFDM band and upstream OFDM band that guarantees a tolerable amount of optical interference has been determined through experiment. The frequency of local oscillator is reduced due to frequency sextupling scheme. The cost of the proposed system is largely reduced. © 2012 Wiley Periodicals, Inc.

5.8 GHz full duplex amplitude shift keying retrodirective interrogator array
Authors: Chan Pak , Fusco V. 
Published: November 2012

AbstractThis article describes a practical demonstration of a complete full‐duplex “amplitude shift keying (ASK)” retrodirective radio frequency identification (RFID) transceiver array.The interrogator incorporates a “retrodirective array (RDA)” with a dual‐conversion phase conjugating architecture in order to achieve better performance than is possible with conventional RFID solutions. Here mixers phase conjugate the incoming signal and a carrier recovery circuit recovers incoming angle of arrival phase information of an encoded amplitude shift keyed signal. The resulting interrogator provides a receiver sensitivity level of −109 dBm. A four element square patch RDA gives a 3 dB automatic beam steering angle of acceptance of ±45°. When compared to an RFID system operating by conventional (non‐retrodirective) means retrodirective action leads to improved range extension of up to 16 times at ±45°. Operator pointing accuracy requirements are also reduced due to automatic retrodirective self‐pointing. These features significantly enhance deployment opportunities requiring long range low equivalent isotropic radiation power (EIRP) and/or RFID tagging of moving platforms. © 2012 Wiley Periodicals, Inc.

AbstractThis is the first investigation report of a dielectric dot, on a thin gold film, as an antenna in optical frequency range. We examine the effect of various parameters of the dot on its resonance and discuss its emission and receiving properties. The emission from an array of dots is more directional and follows pattern multiplication just like radio antennas. The antenna perspective of tiny dots gives a wonderful analogy with classical electromagnetics which might open a new pathway in the field of nanophotonics. © 2012 Wiley Periodicals, Inc.

Triple band‐notched UWB monopole antenna with two resonator structures
Authors: Kim Jang‐Yeol , Kim Nam , Lee Seungwoo , Oh Byoung‐Cheol 
Published: November 2012

AbstractWe propose a novel configuration of a triple band‐notched ultra‐wideband (UWB) antenna. The designed structure is based on an elliptical monopole antenna combined with a complementary split ring resonator (CSRR) structure and a spiral resonator. The spiral resonator can achieve the dual‐band notched performance at WiMAX band and ITU 8 GHz by adjusting the length and width of a spiral line. Besides, the CSRR can obtain the notched band at WLAN 5 GHz by changing the radius of a ring slot. The designed antenna shows that a VSWR of less than 2 was satisfied with a resonant frequency in the range of 1.34–11.4 GHz with a 78.96%, except for triple notched bands. © 2012 Wiley Periodicals, Inc.

Published: November 2012

AbstractAimsGlutamate is a major excitatory transmitter in the central nervous system, controlling lower urinary tract function. Five types of glutamate transporters such as GLAST (EAAT1), GLT‐1 (EAAT2), EAAC‐1 (EAAT3), EAAT4, and EAAT5 have been cloned so far. In the current study we tested whether L‐trans‐pyrrolidine‐2,4‐dicarboxylic acid (L‐trans‐PDC), a non‐selective inhibitor of glutamate transporters that increases endogenous glutamate concentration, can affect the micturition reflex in urethane anesthetized rats.MethodsContinuous cystometrograms (CMG, 0.04 ml/min infusion rate) were performed in two groups of urethane‐anesthetized rats. A group of 18 rats was used for intrathecal administration of 1–10 µg of L‐trans‐PDC via an intrathecal catheter. In the second group of 18 rats, 1–10 µg of L‐trans‐PDC were administered intracerebroventricularly via a catheter inserted into the lateral ventricle. Micturition parameters were recorded and compared before and after drug administration.ResultsIntrathecal administration of L‐trans‐PDC at 1, 3, and 10 µg (n = 6 per dose) increased intercontraction intervals in dose dependent fashion, but did not affect postvoid residual or basal pressure at any doses tested. Intracerebroventricular administration of L‐trans‐PDC at 1, 3, and 10 µg (n = 6 per dose) also increased intercontraction intervals in dose dependent fashion, but did not affect postvoid residual or basal pressure at any doses tested.ConclusionsThe current results show that, in urethane‐anesthetized rats, suppression of glutamate transporters by L‐trans‐PDC has an inhibitory effect on the micturition reflex at supraspinal and spinal sites, possibly via activation of glutamate‐mediated inhibitory pathways.
