An efficient RFID anticollision algorithm using early adjustment of frame length
Authors: Chen Wen‐Tzu 
Published: May 2015

SummaryThis paper proposes a radio frequency identification (RFID) anticollision algorithm to enhance the read performance of the EPCglobal UHF Class‐1 Generation‐2 standard. Our algorithm is based on the mechanism of early adjustment of frame length, as well as dynamic framed slotted ALOHA. To reduce computation complexity, the proposed algorithm adopts a simple rule for a reader to determine when and how the early adjustment starts. Furthermore, the proposed method resorts to at most three examinations of whether the early adjustment should start in each read round. As compared with the algorithms of examining at every time slot, the proposed method can significantly reduce the number of examinations. The normalized throughput of our method can reach a value of up to 34.6%. The advantage of low computation complexity comes at the expense of only 1.4% degradation of throughput. Therefore, it is suitable for most RFID readers built with a capability‐limited microprocessor. Copyright © 2015 John Wiley & Sons, Ltd.
The uFLIP benchmark revisited for evaluating SSDs
Authors: Kang Yoonsuk , Jo Yong‐Yeon , Cha Jaehhyuk , Kim Sang‐Wook , Shin Young Kyun 
Published: May 2015

SummarySolid‐state drives (SSDs) provide higher bandwidth and lower access latency than hard disk drives (HDDs) and thus have been rapidly replacing HDDs. SSD manufacturers, which produce different types of SSDs, do not open their SSD architecture and control firmware in detail. To find the best SSD for a given application, it is necessary to compare and analyze the performances of different kinds of SSDs. A benchmark is widely used to analyze the storage devices performance. However, most existing benchmarks are mainly targeted for HDDs. The uFLIP (understanding Flash IO Patterns) is a benchmark proposed to consider flash devices' characteristics. In this paper, we first exploit the uFLIP benchmark to analyze and to evaluate the performances of different types of SSDs. Through extensive experiments, we have identified common SSD characteristics: (1) the input/output (IO) size and queue depth affect the parallelism that is an inherent characteristic in SSDs; (2) the size of SSDs access space considerably affects the SSDs performance. Then, via a series of experiments, we verify whether the uFLIP benchmark could correctly characterize applications by its micro‐benchmarks. The results reveal that the performance of the uFLIP micro‐benchmarks, produced to have features similar to that of a target application, is quite different from the performance of the target application.

Published: May 2015

SummaryTnnt2, encoding thin‐filament sarcomeric protein cardiac troponin T, plays critical roles in heart development and function in mammals. To develop an inducible genetic deletion strategy in myocardial cells, we generated a new Tnnt2:MerCreMer (Tnnt2MerCreMer/+) knock‐in mouse. Rosa26 reporter lines were used to examine the specificity and efficiency of the inducible Cre recombinase. We found that Cre was specifically and robustly expressed in the cardiomyocytes at embryonic and adult stages following tamoxifen induction. The knock‐in allele on Tnnt2 locus does not impact cardiac function. These results suggest that this new Tnnt2MerCreMer/+ mouse could be applied towards the temporal genetic deletion of genes of interests in cardiomyocytes with Cre‐LoxP technology. The Tnnt2MerCreMer/+ mouse model also provides a useful tool to trace myocardial lineage during development and repair after cardiac injury. genesis 53:377–386, 2015. © 2015 Wiley Periodicals, Inc.

AbstractAcute heart failure is a fatal syndrome. Emergency physicians, cardiologists, intensivists, nurses and other health care providers have to cooperate to provide optimal benefit. However, many treatment decisions are opinion‐based and few are evidenced‐based. This consensus paper provides guidance to practicing physicians and nurses to manage acute heart failure in the pre‐hospital and hospital setting. Criteria of hospitalization and of discharge are described. Gaps in knowledge and perspectives in the management of acute heart failure are also detailed. This consensus paper on acute heart failure might help enable contiguous practice.
(9,10‐Dihydroxyoctadecyl)ammonium: A Structurally Unique Class of Clay Intercalable Surfactants
Authors: Jankovič Luboš , Kronek Juraj , Madejová Jana , Hronský Viktor 
Published: May 2015

AbstractThe structurally unique clay–intercalable (9,10‐dihydroxyoctadecyl)trimethylammonium (OH‐ODTMA) cationic surfactant was synthesized in two steps from commercially available oleylamine. Sodium montmorillonite was modified by a cation‐exchange reaction by using three different octadecyltrimethylamonium ODTMA‐based organic cations. Basal spacings, surfactant configuration, the interlamellar structure, and the thermal stability of the resulting organomontmorillonites were characterized by using X‐ray diffraction, IR spectroscopy, thermogravimetric analysis, and NMR spectroscopy techniques. Magic‐angle spinning 13C NMR spectroscopy demonstrated the coexistence of ordered (all‐trans) and disordered (gauche) alkyl chain conformations. Deconvolution of the NMR spectra indicated that the conformational ordering of the surfactant molecules within the gallery of montmorillonite strongly depended on their orientation, the presence of functional groups, and the temperature. Relative to that found in ODTMA‐MT, the amount of gauche conformers was significantly higher in montmorillonite intercalated with the OH‐ODTMA cation and higher than that in the synthetic precursor, the oleyltrimethylammonium cation. Changes in the ordering of the organic cations were confirmed by FTIR spectroscopy with a distinct frequency shift in the CH stretching and overtone bands. The novel alkylammonium surfactant functionalized with two OH groups in the middle of the backbone represents a prospective ingredient for organoclay–polyurethane nanocomposites.
Electroosmotic flow and Joule heating in preparative continuous annular electrochromatography
Authors: Laskowski René , Bart Hans‐Jörg 
Published: May 2015

An openFOAM “computational fluid dynamic” simulation model was developed for the description of local interaction of hydrodynamics and Joule heating in annular electrochromatography. A local decline of electrical conductivity of the background eluent is caused by an electrokinetic migration of ions resulting in higher Joule heat generation. The model equations consider the Navier–Stokes equation for incompressible fluids, the energy equation for stationary temperature fields, and the mass transfer equation for the electrokinetic flow. The simulations were embedded in commercial ANSYS Fluent software and in open‐source environment openFOAM. The annular gap (1 mm width) contained an inorganic C8 reverse‐phase monolith as stationary phase prepared by an in situ sol–gel process. The process temperature generated by Joule heating was determined by thermal camera system. The local hydrodynamics in the prototype was detected by a gravimetric contact‐free measurement method and experimental and simulated values matched quite well.
Influence of operating parameters on the bio‐photoelectrochemical cell for hydrogen and electricity production

Published: May 2015

Hydrogen and electricity can be produced simultaneously via a dual chamber bio‐photoelectrochemical cell. This cell is designed with a proton exchange membrane to separate the bio‐anode and the n‐type titanium dioxide photocathode. The effects of photocathode size, catholyte pH, illumination intensity, and external resistance on electricity and hydrogen production are investigated. By increasing the photocathode size or decreasing catholyte pH, the performance for hydrogen and electricity production increases. By using photocathode size of 3 cm2 at neutral pH, the highest power density of 47.4 mW m−2 was obtained under 350 W light irradiation. Hydrogen production rate of 14.1 uL h−1 can be achieved with external resistance of 1,000 Ω. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1796–1800, 2015
Income Elasticity of Vaccines Spending versus General Healthcare Spending
Authors: Alfonso Y. Natalia , Ding Guiru , Bishai David 
Published: May 2015

AbstractUsing cross‐country data on gross domestic product and national expenditure on vaccines, we estimate and compare the income elasticity of vaccine expenditure and general curative healthcare expenditure. This study provides the first evidence on the national income elasticity of vaccination spending. Both fixed and random effects models are applied to data from 84 countries from 2010 to 2011. The income elasticities for healthcare expenditure and vaccine expenditure are 0.844 and 0.336, respectively. Despite vaccines' high cost‐effectiveness, the national propensity to spend income on vaccines as income increases lags behind general health care. The low income elasticity of vaccine spending means that relying on economic growth alone will provide an unacceptably slow trajectory to achieving high vaccine coverage levels.

Pharmacodynamics of norepinephrine reuptake inhibition: Modeling the peripheral and central effects of atomoxetine, duloxetine, and edivoxetine on the biomarker 3,4‐dihydroxyphenylglycol in humans
Authors: Kielbasa William , Lobo Evelyn 
Published: May 2015

AbstractNorepinephrine, a neurotransmitter in the autonomic sympathetic nervous system, is deaminated by monoamine oxidase to 3,4‐dihydroxyphenylglycol (DHPG). Inhibition of the NE transporter (NET) using DHPG as a biomarker was evaluated using atomoxetine, duloxetine, and edivoxetine as probe NET inhibitors. Pharmacokinetic and pharmacodynamic data were obtained from healthy subjects (n = 160) from 5 clinical trials. An indirect response model was used to describe the relationship between drug plasma concentration and DHPG concentration in plasma and cerebrospinal fluid (CSF). The baseline plasma DHPG concentration (1130–1240 ng/mL) and Imax (33%–37%) were similar for the 3 drugs. The unbound plasma drug IC50 (IC50U) based on plasma DHPG was 0.973 nM for duloxetine, 0.136 nM for atomoxetine, and 0.041 nM for edivoxetine. The baseline CSF DHPG concentration (1850–2260 ng/mL) was similar for the 3 drugs, but unlike plasma DHPG, the Imax for DHPG was 38% for duloxetine, 53% for atomoxetine, and75% for edivoxetine. The IC50U based on CSF DHPG was 2.72 nM for atomoxetine, 1.22 nM for duloxetine, and 0.794 nM for edivoxetine. These modeling results provide insights into the pharmacology of NET inhibitors and the use of DHPG as a biomarker.
Weighing the adverse cardiac effects of fluoroquinolones: A risk perspective
Authors: Mehrzad Raman , Barza Michael 
Published: May 2015

AbstractA rare side effect of fluoroquinolone (FQ) antibiotics is QT prolongation, which may result in serious arrhythmias. Most published comparative trials describe the relative risks among the drug class but do not focus on the incidence of serious arrhythmias. It is important for the prescriber to have a sense not only of relative risk but also of incidence to balance the risks against the other attributes of the individual members of the drug class. A review of English‐language literature was performed to identify trials that provide data on the relative risk and, when able to be calculated, the incidence of adverse cardiac events among the commonly used FQs. Moxifloxacin had a several‐fold higher risk of cardiac arrhythmias than levofloxacin or ciprofloxacin in randomized trials. However, the actual event rate was low in 2 of 3 studies. Given inconsistencies among the studies and the relative rarity of the events, the clinician need not base the choice of drug primarily on concern for a cardiac arrhythmia except in patients at the highest risk of such an event.

Published: May 2015

ABSTRACTA multitude of morphological aspects of the human middle ear (ME) were studied qualitatively and/or quantitatively through the postprocessing and interpretation of micro‐CT (micro X‐ray computed tomography) data of six human temporal bones. The samples were scanned after phosphotungstic acid staining to enhance soft‐tissue contrast. The influence of this staining on ME ossicle configuration was shown to be insignificant. Through postprocessing, the image data were converted into surface models, after which the approaches diverged depending on the topics of interest. The studied topics were: the ME ligaments; morphometric and mechanical parameters of the ossicles relating to inertia and the ossicular lever arm ratio; the morphology of the distal incus; the contact surface areas of the tympanic membrane (TM) and of the stapes footplate; and the thickness of the TM, round window of the cochlea, ossicle joint spaces, and stapedial annular ligament. Some of the resulting insights are relevant in ongoing discussions concerning ME morphology and mechanical functions, while other results provide quantitative data to add to existing data. All findings are discussed in the light of other published data and many are relevant for the construction of mechanical finite element simulations of the ME. J.

Effect of resection depth of early glottic cancer on vocal outcome: An optimized finite element simulation
Authors: Mau Ted , Palaparthi Anil , Riede Tobias , Titze Ingo R. 
Published: May 2015

Objectives/HypothesisTo test the hypothesis that subligamental cordectomy produces superior acoustic outcome than subepithelial cordectomy for early (T1–2) glottic cancer that requires complete removal of the superficial lamina propria but does not involve the vocal ligament.Study DesignComputer simulation.MethodsA computational tool for vocal fold surgical planning and simulation (the National Center for Voice and Speech Phonosurgery Optimizer‐Simulator) was used to evaluate the acoustic output of alternative vocal fold morphologies. Four morphologies were simulated: normal, subepithelial cordectomy, subligamental cordectomy, and transligamental cordectomy (partial ligament resection). The primary outcome measure was the range of fundamental frequency (F0) and sound pressure level (SPL). A more restricted F0‐SPL range was considered less favorable because of reduced acoustic possibilities given the same range of driving subglottic pressure and identical vocal fold posturing.ResultsSubligamental cordectomy generated solutions covering an F0‐SPL range 82% of normal for a rectangular vocal fold. In contrast, transligamental and subepithelial cordectomies produced significantly smaller F0‐SPL ranges, 57% and 19% of normal, respectively.ConclusionThis study illustrates the use of the Phonosurgery Optimizer‐Simulator to test a specific hypothesis regarding the merits of two surgical alternatives. These simulation results provide theoretical support for vocal ligament excision with maximum muscle preservation when superficial lamina propria resection is necessary but the vocal ligament can be spared on oncological grounds. The resection of more tissue may paradoxically allow the eventual recovery of a better speaking voice, assuming glottal width is restored. Application of this conclusion to surgical practice will require confirmatory clinical data.Level of EvidenceN/A. Laryngoscope, 125:1892–1899, 2015

Objectives and HypothesisOur objectives were to characterize the quality of acute sinusitis care and to identify nonclinical factors associated with antibiotic use for acute sinusitis. We hypothesized that we would identify provider‐level factors associated with antibiotic use.Study DesignRetrospective cohort at a single academic institution.MethodsWe developed and clinically annotated an administrative dataset of adult patients diagnosed with acute sinusitis between January 1, 2005, and December 31, 2006. We used identify factors associated with receipt of antibiotics.ResultsWe find that 66.0% of patients with mild symptoms of short duration are given antibiotics, and that nonclinical factors, including the individual provider, the provider's specialty, and the presence of a medical trainee, significantly influence antibiotic use. Relative to internal medicine providers, family medicine providers use fewer antibiotics, and emergency medicine providers use more antibiotics for acute sinusitis.ConclusionsAntibiotics continue to be overused for patients with mild acute sinusitis of short duration. Nonclinical characteristics, including the individual provider, the provider's specialty, and the presence of a medical trainee, significantly influence use of antibiotics for acute sinusitis.Level of Evidence4.

Published: May 2015

PurposeTo accelerate T1ρ quantification in cartilage imaging using combined compressed sensing with iterative locally adaptive support detection and JSENSE.MethodsTo reconstruct T1ρ images from accelerated acquisition at different time of spin‐lock (TSLs), we propose an approach to combine an advanced compressed sensing (CS) based reconstruction technique, LAISD (locally adaptive iterative support detection), and an advanced parallel imaging technique, JSENSE. Specifically, the reconstruction process alternates iteratively among local support detection in the domain of principal component analysis, compressed sensing reconstruction of the image sequence, and sensitivity estimation with JSENSE. T1ρ quantification results from accelerated scans using the proposed method are evaluated using in vivo knee cartilage data from bilateral scans of three healthy volunteers.ResultsT1ρ maps obtained from accelerated scans (acceleration factors of 3 and 3.5) using the proposed method showed results comparable to conventional full scans. The T1ρ errors in all compartments are below 1%, which is well below the in vivo reproducibility of cartilage T1ρ reported from previous studies.ConclusionThe proposed method can significantly accelerate the acquisition process of T1ρ quantification on human cartilage imaging without sacrificing accuracy, which will greatly facilitate the clinical translation of quantitative cartilage MRI.

Improving the performance of Sb2Se3 thin film solar cells over 4% by controlled addition of oxygen during film deposition
Authors: Liu Xinsheng , Chen Chao , Wang Liang , Zhong Jie , Luo Miao , Chen Jie , Xue Ding‐Jiang , Li Dengbing , Zhou Ying , Tang Jiang 
Published: May 2015

AbstractSb2Se3 has attracted great research interest very recently as a promising absorber material for thin film photovoltaics due to its suitable bandgap, high absorption coefficient, and non‐toxic, low cost, and earth abundant nature. In this work, a significant efficiency improvement to 4.8% of superstrate cadmium sulfide (CdS)/Sb2Se3 solar cells is obtained by the controlled addition of oxygen during thermal evaporation of Sb2Se3 films. Systematic materials and device physics characterization reveal that oxygen addition during Sb2Se3 film evaporation significantly improves the CdS/Sb2Se3 heterojunction quality through effective passivation of interfacial defect states, resulting in a substantial enhancement in device circuit voltage and short circuit current density. The 4.8% device is the highest efficiency thus far reported for Sb2Se3 thin film solar cells. Copyright © 2015 John Wiley & Sons, Ltd.
Can Travelling Mothers Ever Arrive? Articulating Internal and International Migration within a Transnational Perspective of Care
Authors: Huang Shu‐Mei 
Published: May 2015

AbstractTracing the continuously changing dynamics between China and its quasi‐independent capitalist ‘special territory’, Hong Kong, this paper brings together the under‐recognised cross‐border caregivers and over‐recognised care consumers in the wake of multiple care crises, articulating how internal and international migration clashes in the borderlands crossed by various kinds of travelling mothers from the Mainland. With a focus on care as social practices and relations, it observes how the boundary between internal and international migrations shifts and multiplies as care is alienated, displaced, and commodified. To understand the mobility and multiplicity of borders, it adopts an integrated framework that links internal and international migration studies, and more importantly, attends to care. A transnational perspective on the dynamics of mobile, unpaid care labour, as they play out within the boundaries of the same, recently ‘re‐integrated’ country, further suggests that attention must be paid to the conceptual terrains and lived experiences of those who live and move in‐between internal and international migration regimes, especially the invisible caregivers who frequently travel across borders.
