Authors: Mahendra Adhi , Sutarya Dede 
Published: July 2016

Meningkatnya penggunaan dan penerapan hidrogen sebagai sumber energi terbarukan atau aplikasi pada proses industri, telah meningkatkan tekanan untuk memastikan penanganan keselamatan serta pemantauannya. Masalah keselamatan yang berkaitan dengan gas hidrogen lebih jauh dihambat oleh mahalnya instrumentasi yang diperlukan untuk mengukur persentase batas ledakan, laju aliran dan tekanan yang dihasilkan. Solusi inovatif untuk mengatasi isu-isu keselamatan hidrogen dan sensor fisik yang mahal adalah dengan menggunakan sensor virtual berdasarkan jaringan syaraf tiruan yang belajar dari data untuk memprediksi parameter yang berkaitan dengan keselamatan hidrogen. Penelitian ini bertujuan untuk mendapatkan dataset yang enggambarkan seluruh perilaku proses sintering dengan atmosfir hidrogen. Dalam penelitian ini dikembangkan sebuah sistem akuisisi data untuk proses sintering serta mengujinya pada proses sintering sebenarnya untuk mendapatkan data yang diperlukan. Hasil percobaan pada sistem akuisisi data secara online untuk mengukur variabel proses menunjukkan kinerja sistem yang baik. Data yang diperoleh dapat menggambarkan perilaku keseluruhan hidrogen dalam proses sintering. Dengan demikian data ini dapat digunakan sebagai dataset untuk pemodelan jaringan saraf tiruan dalam memprediksi parameter keselamatan hidrogen dalam studi berikutnya.

Towards ecohydrological drought monitoring and prediction using a land data assimilation system: A case study on the Horn of Africa drought (2010–2011)
Authors: Sawada Yohei , Koike Toshio 
Published: June 2016

AbstractDespite the importance of the ecological and agricultural aspects of severe droughts, no drought monitoring and prediction framework based on a land data assimilation system (LDAS) has been developed to monitor and predict vegetation dynamics in the middle of droughts. In this study, we applied a LDAS that can simulate surface soil moisture, root‐zone soil moisture, and vegetation dynamics to the Horn of Africa drought in 2010–2011 caused by the precipitation deficit in two consecutive rainy seasons. We successfully simulated the ecohydrological drought quantified by the model‐estimated soil moistures and leaf area index (LAI). The root‐zone soil moisture and LAI are good indicators of prolonged droughts because they reflect the long‐term effects of past precipitation deficit. The precipitation deficit in 2010 significantly affected the land surface condition of the next rainy season in 2011, which indicated the importance of obtaining accurate initial soil moisture and LAI values for prediction of multiseasonal droughts. In addition, the general circulation model‐based seasonal meteorological prediction showed good performance in predicting land surface conditions of the Horn of Africa drought.

Published: June 2016

AbstractBinding interactions between twisted cucurbit[14]uril (tQ[14]) and twenty standard amino acids (AAs) have been investigated by NMR spectroscopy and isothermal titration calorimetry (ITC) in aqueous HCl solutions and in DMSO. The results showed that tQ[14] displays clear binding affinity for AAs with a positively charged side chain or containing an aromatic ring, but weaker binding affinity for AAs with hydrophobic or polar side chains, with the binding mode depending on the type of side chain present in the AAs.
Bioorthogonal Chemical Reporters for Monitoring Unsaturated Fatty‐Acylated Proteins
Authors: Thinon Emmanuelle , Percher Avital , Hang Howard C. 
Published: June 2016

AbstractDietary unsaturated fatty acids, such as oleic acid, have been shown to be covalently incorporated into a small subset of proteins, but the generality and diversity of this protein modification has not been studied. We synthesized unsaturated fatty‐acid chemical reporters and determined their protein targets in mammalian cells. The reporters can induce the formation of lipid droplets and be incorporated site‐specifically onto known fatty‐acylated proteins and label many proteins in mammalian cells. Quantitative proteomics analysis revealed that unsaturated fatty acids modify similar protein targets to saturated fatty acids, including several immunity‐associated proteins. This demonstrates that unsaturated fatty acids can directly modify many proteins to exert their unique and often beneficial physiological effects in vivo.

Published: June 2016

BACKGROUNDPopulation‐based studies have demonstrated survival disparities related to socioeconomic factors for patients with acute myeloid leukemia (AML). The objective of the current study was to determine whether the local health care infrastructure, represented by Area Health Education Centers (AHEC) region, or treating center experience, represented by National Cancer Institute Comprehensive Cancer Center (NCICCC) designation, were associated with outcomes among patients with AML in North Carolina.METHODSPatients who were diagnosed with AML from 2003 to 2009 were identified using the University of North Carolina Lineberger Integrated Cancer Information and Surveillance System, a database linking insurance claims to the North Carolina Cancer Registry. A Cox proportional‐hazards model was used to explore survival based on AHEC region. A subset of patients who received inpatient chemotherapy was examined to evaluate the impact of treatment at an NCICCC.RESULTSNine hundred patients were identified in the study period, 553 of whom received inpatient chemotherapy therapy within 30 days of diagnosis. Almost one‐half of these patients (n = 294) received chemotherapy at a non‐NCICCC. Among the patients who received intensive inpatient therapy, residence in 3 of 9 AHEC regions was associated with a higher risk of mortality (hazard ratio: range, 1.97‐4.03; P < .01) at 1 year in multivariate analysis. Treatment at a non‐NCICCC was not associated with an increased risk of mortality at 1 year (hazard ratio, 1.25; 95% confidence interval, 0.95‐1.65).CONCLUSIONSSurvival among patients with AML in North Carolina varies according to geographic region. Further examination of local practice and referral patterns may inform strategies to improve AML outcomes across the state. Cancer 2016;122:3041‐3050. © 2016 American Cancer Society.
Joint impact of sensing time and IED parameter on the performance of an energy efficient cognitive radio system
Authors: Bhowmick Abhijit , Dhar Roy Sanjay , Kundu Sumit 
Published: June 2016

SummaryJoint impact of sensing time and improved energy detector (IED) parameter is evaluated for an energy efficient cooperative cognitive radio (CR) system where the CR users use IED. The aim of this work is to design the CR system in such a way that it can achieve two objectives for a given level of protection on primary user: (i) optimization of sensing time to make balance between detection performance and throughput and (ii) appropriate allocation of energy between sensing time and transmission time so as to enhance the energy efficiency of the CR system. The key parameters such as sensing time and IED parameter are set appropriately to meet the objectives. The performance is assessed in terms of throughput and energy efficiency of the system. The effect of the sensing time and the IED parameter on the performance is evaluated under a collision constraint. Furthermore, the optimal sensing time and IED parameter are investigated jointly for which the higher throughput as well as maximum energy efficiency can be obtained, and at the same time, a desired detection probability can also be maintained by the CR system.

Published: June 2016

BACKGROUNDPrevious research investigating the impact of delayed intensive care unit (ICU) transfer on outcomes has utilized subjective criteria for defining critical illness.OBJECTIVETo investigate the impact of delayed ICU transfer using the electronic Cardiac Arrest Risk Triage (eCART) score, a previously published early warning score, as an objective marker of critical illness.DESIGNObservational cohort study.SETTINGMedical‐surgical wards at 5 hospitals between November 2008 and January 2013.PATIENTSWard patients.INTERVENTIONNone.MEASUREMENTSeCART scores were calculated for all patients. The threshold with a specificity of 95% for ICU transfer (eCART ≥ 60) denoted critical illness. A logistic regression model adjusting for age, sex, and surgical status was used to calculate the association between time to ICU transfer from first critical eCART value and in‐hospital mortality.RESULTSA total of 3789 patients met the critical eCART threshold before ICU transfer, and the median time to ICU transfer was 5.4 hours. Delayed transfer (>6 hours) occurred in 46% of patients (n = 1734) and was associated with increased mortality compared to patients transferred early (33.2% vs 24.5%, P < 0.001). Each 1‐hour increase in delay was associated with an adjusted 3% increase in odds of mortality (P < 0.001). In patients who survived to discharge, delayed transfer was associated with longer hospital length of stay (median 13 vs 11 days, P < 0.001).CONCLUSIONSDelayed ICU transfer is associated with increased hospital length of stay and mortality. Use of an evidence‐based early warning score, such as eCART, could lead to timely ICU transfer and reduced preventable death.

Published: June 2016

ObjectivesWe aim to develop an imaging technique for visualization of the Eustachian tube (ET) lumen.Study DesignA prospective, experimental study in an animal model and in human cadaver specimens.MethodsApplying iodixanol to the middle ear in two human temporal bone specimens, followed by computed tomography (CT) examinations, we optimized contrast dilution, CT algorithm, and head positioning for visualization of contrast passage through the ET.Myringotomy was performed on eight rabbits. Based on the cadaver study, a 20% iodixanol solution was applied to the middle ear, and subsequent CT scans were performed to observe iodixanol in the epipharynx. For some animals, the procedure was repeated on the contralateral ear. We performed the procedure twice on four subjects. Twenty examinations were included.Iodixanol appearance in the ET and the epipharyngeal orifice was assessed qualitatively on CT scans. The tympanic membrane was inspected after 1 or 2 weeks, and histopathological examination of six contrast‐exposed temporal bones was performed.ResultsThe cadaver study provided information on imaging technique and contrast dosage. In rabbits, iodixanol passed through the ET in 19 of the 20 ears. Qualitatively, optimal visualization was seen after 9 to 12 minutes. Clinical inspection after 1 or 2 weeks revealed normal middle ear status. Histopathological samples showed no sign of inflammatory reaction in the tympanic membrane, middle ear, or ET.ConclusionIodixanol application to the middle ear is feasible, safe, and demonstrates patency of the ET.Level of EvidenceN/A.
Poly(ether sulfone)s using a rigid dibenzothiophene dioxide heterocycle
Authors: Kortan Adam M. , Cannizzaro Randall J. , Robb Maxwell J. , Knauss Daniel M. 
Published: June 2016

ABSTRACTPoly(aryl ether)s were prepared by nucleophilic aromatic substitution using conformationally restricted dichloro‐ and difluorodibenzothiophene dioxide heterocyclic monomers with bisphenol A or bisphenol AF. The heterocyclic monomers were prepared from the bis(4‐halophenyl) sulfones in two steps via lithiation followed by copper catalyzed intramolecular coupling and characterized by 1H, 13C, 19F NMR spectroscopy and GC/MS. Reactivity of the fluorine containing monomer was examined using semi‐empirical methods and NMR spectroscopy measurements and found to be potentially more reactive than bis(4‐fluorophenyl) sulfone, even with a conformationally locked sulfone as the electron withdrawing group. Successful polymerizations of both the fluorine and chlorine containing monomers with bisphenol A and bisphenol AF nucleophiles were accomplished, providing polymers with number average molecular weights of approximately 45 kg/mol (difluoro monomer) and 10–20 kg/mol (dichloro monomer). The polymers exhibited high Tgs ranging from 238 to 256 °C and displayed good thermal stability with 5% degradation temperatures in air from 453–510 °C, depending on molecular weight and bisphenol composition. © 2016 Wiley Periodicals, Inc.

Capturing Functional Independence Measure (FIM®) Ratings
Authors: Torres Audrey 
Published: June 2016

Abstract

Purpose:
The aim of the study was to identify interventions to capture admission functional independence measure (FIM®) ratings on the day of admission to an inpatient rehabilitation facility.

Design:
A quantitative evidence-based practice quality improvement study utilizing descriptive statistics.

Methods:
Admission FIM® ratings from patients discharged in June 2012 (retrospective review) were compared to admission FIM® ratings from patients discharged in June 2014 (prospective review). The logic model was utilized to determine the project inputs, outputs, and outcomes.

Findings:
Interventions to capture admission FIM® ratings on the day of admission are essential to accurately predict the patient’s burden of care, length of stay, and reimbursement. Waiting until Day 2 or Day 3 after admission to capture the admission FIM® assessment resulted in inflated admission FIM® ratings and suboptimal quality outcomes.

Conclusion/Clinical Relevance:
Interventions to capture admission FIM® ratings on the day of admission were successful at improving the quality of care, length of stay efficiency, and accurately recording admission FIM® ratings to determine the patient’s burden of care.

Abstract
Stem cells possess the ability to home in and travel to damaged tissue when injected intravenously. For the cells to exert their therapeutic effect, they must cross the blood vessel wall and enter the surrounding tissues. The mechanism of extravasation injected stem cells employ for exit has yet to be characterized. Using intravital microscopy and a transgenic zebrafish line Tg(fli1a:egpf) with GFP-expressing vasculature, we documented the detailed extravasation processes in vivo for injected stem cells in comparison to white blood cells (WBCs). While WBCs left the blood vessels by the standard diapedesis process, injected cardiac and mesenchymal stem cells underwent a distinct method of extravasation that was markedly different from diapedesis. Here, the vascular wall undergoes an extensive remodeling to allow the cell to exit the lumen, while the injected cell remains distinctively passive in activity. We termed this process Angio-pello-sis, which represents an alternative mechanism of cell extravasation to the prevailing theory of diapedesis.

Experimental study on steel built‐up column moment connections with top and bottom trapezoidal side plates
Authors: Shiravand M.R. , Deylami A. 
Published: June 2016

SummaryBuilt‐up and box columns are used extensively in steel structures. A kind of built‐up column is composed of two I rolled shapes separated by calculated interval and welded between two cover plates. The uncertainties due to these columns are the flexibility of the column cover plates under the transferred beam flange plate forces and the brittle behavior of the groove weld between the beam flange plate and the column cover plate. The top and bottom trapezoidal side plates are proposed to improve the behavior of these column moment connections. Using this approach, the total beam flange forces transfer to the lateral sides of the column, parallel to the beam web, by means of top and bottom side plates. An experimental test is developed to study the behavior of the proposed connection under cyclic loading. The results indicate that the proposed connection has sufficient strength and ductility to apply in special moment frames. Also, the rehabilitated connection eliminates the vulnerabilities of deformation of the column cover plate and brittle fracture of groove welds in conventional connections.

Formalisation of the computation of the echelon form of a matrix in Isabelle/HOL
Authors: Aransay Jesús , Divasón Jose 
Published: June 2016

Abstract
In this contribution we present a formalised algorithm in the Isabelle/HOL proof assistant to compute echelon forms, and, as a consequence, characteristic polynomials of matrices. We have proved its correctness over Bézout domains, but its executability is only guaranteed over Euclidean domains, such as the integer ring and the univariate polynomials over a field. This is possible since the algorithm has been parameterised by a (possibly non-computable) operation that returns the Bézout coefficients of a pair of elements of a ring. The echelon form is also used to compute determinants and inverses of matrices. As a by-product, some algebraic structures have been implemented (principal ideal domains, Bézout domains, etc.). In order to improve performance, the algorithm has been refined to immutable arrays inside of Isabelle and code can be generated to functional languages as well.
Waypoint Following for Differentially Driven Wheeled Robots with Limited Velocity Perturbations
Authors: Pazderski Dariusz 
Published: June 2016

AbstractIn this paper a unified motion control strategy dedicated for the waypoint following task realized by a differentially driven robot is presented. It is assumed that the vehicle moves with limited velocities and accelerations in order to reduce excessive slip and skid effects. In order to include operational constraints, a motion planner is combined with a universal stabilizer taking advantage of transverse functions. To improve tracking precision translated transverse functions are deployed and a new adaptive technique for the controller tuning is proposed. During the motion planning stage an auxiliary trajectory connecting points in the configuration space and satisfying assumed phase constraints is generated. The resulting motion execution system has been implemented on a laboratory-scale skid-steering mobile robot, which served as platform for experimental validation of presented algorithms.
The Controversial Star-Formation History and Helium Enrichment of the Milky Way Bulge
Authors: Nataf David M. 
Published: June 2016

AbstractThe stellar population of the Milky Way bulge is thoroughly studied, with a plethora of measurements from virtually the full suite of instruments available to astronomers. It is thus perhaps surprising that alongside well-established results lies some substantial uncertainty in its star-formation history. Cosmological models predict the bulge to host the Galaxy's oldest stars for [Fe/H] ≲ −1, and this is demonstrated by RR Lyrae stars and globular cluster observations. There is consensus that bulge stars with [Fe/H] ≲ 0 are older than t ≈ 10 Gyr. However, at super-solar metallicity, there is a substantial unresolved discrepancy. Data from spectroscopic measurements of the main-sequence turnoff and subgiant branch, the abundances of asymptotic giant branch stars, the period distribution of Mira variables, the chemistry and central-star masses of planetary nebulae, all suggest a substantial intermediate-age population (t ≈ 3 Gyr). This is in conflict with predictions from cosmologically motivated chemical evolution models and photometric studies of the main-sequence turnoff region, which both suggest virtually no stars younger than t ≈ 8 Gyr. A possible resolution to this conflict is enhanced helium-enrichment, as this would shift nearly all of the age estimates in the direction of decreasing discrepancy.
The 3D Structure of the Galactic Bulge
Authors: Zoccali Manuela , Valenti Elena 
Published: June 2016

AbstractWe review the observational evidences concerning the three-dimensional structure of the Galactic bulge. Although the inner few kpc of our Galaxy are normally referred to asthe bulge, all the observations demonstrate that this region is dominated by a bar, i.e., the bulge is a bar. The bar has a boxy/peanut (X-shaped) structure in its outer regions, while it seems to become less and less elongated in its innermost region. A thinner and longer structure departing from the main bar has also been found, although the observational evidences that support the scenario of two separate structures has been recently challenged. Metal-poor stars ([Fe/H] ≲ −0.5 dex) trace a different structure, and also have different kinematics.
