Readership are Poor Indicators of Research Excellence : Introducing TrueImpactDataset , a New Dataset for Validating Research Evaluation Metrics Conference or Workshop Item

In this paper we show that citation counts and Mendeley readership are poor indicators of research excellence. Our experimental design builds on the assumption that a good evaluation metric should be able to distinguish publications that have changed a research field from those that have not. The experiment has been conducted on a new dataset for bibliometric research which we call TrueImpactDataset. TrueImpactDataset is a collection of research publications of two types – research papers which are considered seminal work in their area and papers which provide a survey (a literature review) of a research area. The dataset also contains related metadata, which include DOIs, titles, authors and abstracts. We describe how the dataset was built and provide overview statistics of the dataset. We propose to use the dataset for validating research evaluation metrics. By using this data, we show that widely used research metrics only poorly distinguish excellent research.
Resource Allocation with Genetic Algorithm and SS Grouping for Uplinks in IEEE 802.16 Systems

In this thesis, a resource allocation with genetic algorithm and SS grouping (GGRA) scheme is proposed for IEEE 802.16 uplink communication systems. The GGRA scheme designs a rate assignment strategy applied with a predefined residual lifetime to dynamically allocate resource to each service type. It also aggregates high correlation subscriber stations (SSs) into the same group to avoid mutual user interference and adopts genetic algorithm to find an optimal assignment vector. It can maximize the system throughput while satisfying the QoS requirements. Simulation results show that the proposed GGRA scheme has better performance than the EFS algorithm and the MLWDF algorithm in system throughput, voice/video packet dropping rate, unsatisfied ratio of HTTP users/packets, and FTP throughput. It can also be found that the GGRA scheme has a feasible computation complexity so that it is feasible in real applications.
Association study of MMP 8 gene in osteoarthritis

Objectives: Osteoarthritis (OA) is a joint disease common in the elderly. There is a prior functional evidence for different matrix metalloproteinases (MMPs), such as MMP8 and MMP9, having a role in the breakdown of cartilage extracellular matrix in OA. Thus, we analyzed whether the common genetic variants of MMP8 and MMP9 contribute to the risk of OA. Materials and methods: In total, 13 common tagging single-nucleotide polymorphisms (SNPs) were studied in a discovery knee OA cohort of 185 cases and 895 controls. For validation, two knee OA replication cohorts and two hand OA replication cohorts were studied (altogether 1369 OA cases, 4445 controls in the five cohorts). The χ test for individual study cohorts and Cochran–Mantel–Haenszel test for combined meta-analysis were calculated using Plink. Results: The rs1940475 SNP in MMP8 showed suggestive association in the discovery cohort (OR = 0.721, 95% CI 0.575–0.906; p = 0.005). Other knee and hand OA replication study cohorts showed similar trend for the predisposing allele without reaching statistical significance in independent replication cohorts nor in their meta-analysis (p > 0.05). Meta-analysis of all five hand and knee OA study cohorts yielded a p-value of 0.027 (OR = 0.904, 95% CI 0.826–0.989). Conclusions: Initial analysis of the MMP8 gene showed suggestive association between rs1940475 and knee OA, but the finding did not replicate in other study cohorts, even though the trend for predisposing allele was similar in all five cohorts. MMP-8 is a good biological candidate for OA, but our study did not find common variants with significant association in the gene.

UvA-DARE ( Digital Academic Repository ) Beat processing is pre-attentive for metrically simple rhythms with clear accents : An ERP

The perception of a regular beat is fundamental to music processing. Here we examine whether the detection of a regular beat is pre-attentive for metrically simple, acoustically varying stimuli using the mismatch negativity (MMN), an ERP response elicited by violations of acoustic regularity irrespective of whether subjects are attending to the stimuli. Both musicians and non-musicians were presented with a varying rhythm with a clear accent structure in which occasionally a sound was omitted. We compared the MMN response to the omission of identical sounds in different metrical positions. Most importantly, we found that omissions in strong metrical positions, on the beat, elicited higher amplitude MMN responses than omissions in weak metrical positions, not on the beat. This suggests that the detection of a beat is preattentive when highly beat inducing stimuli are used. No effects of musical expertise were found. Our results suggest that for metrically simple rhythms with clear accents beat processing does not require attention or musical expertise. In addition, we discuss how the use of acoustically varying stimuli may influence ERP results when studying beat processing.

Salem numbers as Mahler measures of nonreciprocal units

f(x) = a(x− α1) . (x− αn) ∈ C[x], where a 6= 0, its Mahler measure is defined by M(f) := |a| ∏n j=1 max{1, |αj |}. If f(x) = (x−α1) . (x−αn) ∈ Q[x] is irreducible over the field Q, we denote by Kf its splitting field Q(α1, . . . , αn) and by Gf = Gal(Kf/Q) its Galois group. Also, the polynomial f is called reciprocal if the set {α1, . , αn} of its roots is equal to {α−1 1 , . , α−1 n }, i.e. f(x) = ±xnf(x−1), and nonreciprocal otherwise. A root α > 1 of a monic irreducible polynomial f in Z[x] of degree 2n ≥ 4 is called a Salem number if f is reciprocal and has 2n − 2 roots on the unit circle |z| = 1. Let L0 be the set of all possible Mahler measures of nonreciprocal (but not necessarily irreducible) polynomials in Z[x]. Various aspects of the set of all Mahler measures
Fitting Mixture Models with CVaR Constraints

Standard methods of fitting finite mixture models mostly take into account the majority of observations in the center of the distribution. This paper considers the case where the decision maker wants to make sure that the tail of the fitted distribution is at least as heavy as the tail of an empirical distribution. For instance, in nuclear engineering, where probability of exceedance (POE) needs to be estimated, it is important to fit correctly tails of the distributions. The goal of this paper is to supplement the standard methodology and to assure an appropriate heaviness of the fitted tails. We consider a new CVaR distance between distributions, that is a convex function with respect to weights of mixture. We have conducted a case study demonstrating efficiency of the approach. Weights of normal mixture are found by minimizing CVaR distance between the mixture and the empirical distribution. We have suggested convex constraints on weights, assuring that the tail of the mixture is as fat as the tail of empirical distribution.
THE MEDIATING ROLE OF MEANING IN LIFE IN THE RELATIONSHIP BETWEEN MEMORABLE TOURISM EXPERIENCES AND SUBJECTIVE WELL-BEING

Due to varying tourist motivations and needs, involvement in new experiences has different individual consequences. This paper examines the predictive relationship between memorable tourism experience (MTE), meaning in life (MIL) and subjective well-being (SWB). It further investigates whether meaning in life mediates memorable tourism experience’s influence on subjective well-being. The study design was cross-sectional, with data collected from 283 tourists visiting Cappadocia, Turkey. Although all variables were positively correlated, SEM analyses revealed that meaning in life mediated the association of memorable tourism experience with life satisfaction but not positive affect. These findings are discussed considering the role of meaning in life in the link between dimensions of MTE and SWB.
Non-Invasive Genotyping of Honey Bee Queens Apis mellifera L.: Transition of the DraI mtDNA COI-COII Test to In Silico

Simple Summary Each honey bee colony has a single queen which plays a crucial role in the survival and wellbeing of the entire hive. Honey bee genetic analysis and selection and breeding programs rely on destructive methods using worker bees; workers are numerous in a colony and can be quickly replaced. In this study, we tested and validated a fast and efficient non-destructive method to conduct genetic analysis directly on honey bee queens. We also describe a new method for the transition to in silico of a widely used honey bee genetic marker by reconciling both cleaved amplified polymorphic sequences and Sanger sequencing approaches. Both new approaches will provide significant service to honey bee breeding and selection programs, as well as facilitating and standardizing honey bee haplotype identification among research institutions. Abstract The honey bee Apis mellifera L. colony is headed by a single and indispensable queen, whose duty it is to ensure brood production and provide pheromonal stability within the colony. This study presents a non-invasive method that allows the identification of the queen maternal lineage and subspecies using the remaining tissue of her clipped wing. The DraI mtDNA COI-COII (DmCC) test was applied to various sizes of queen and worker wings and the results were compared with data obtained from other bee tissues. Furthermore, we propose a new method allowing in silico transition of the DmCC test and haplotype identification based on extended sequencing of the tRNAleu and COII genes. Our results show that DNA extracted by Chelex 10% from one-third of a queen’s wing is deemed adequate for a successful identification of her maternal evolutionary lineage, haplotype and subspecies. The in silico method proposed in this study fully adheres to the established guidelines of the DmCC, provides a universal standard for haplotype identification, and offers faster and more precise results by reconciling both cleaved amplified polymorphic sequences (CAPS) and Sanger sequencing approaches.
Long-Term Impact of Suppressive Antibiotic Therapy on Intestinal Microbiota

The aim was to describe the safety of indefinite administration of antibiotics, the so-called suppressive antibiotic therapy (SAT) and to provide insight into their impact on gut microbiota. 17 patients with SAT were recruited, providing a fecal sample. Bacterial composition was determined by 16S rDNA massive sequencing, and their viability was explored by PCR-DGGE with and without propidium monoazide. Presence of antibiotic multirresistant bacteria was explored through the culture of feces in selective media. High intra-individual variability in the genera distribution regardless of the antibiotic or antibiotic administration ingestion period, with few statistically significant differences detected by Bray-Curtis distance-based principle component analysis, permutational multivariate analysis of variance and linear discriminant analysis effect size analysis. However, the microbiota composition of patients treated with both beta-lactams and sulfonamides clustered by a heat map. Curiously, the detection of antibiotic resistant bacteria was almost anecdotic and CTX-M-15-producing E. coli were detected in two subjects. Our work demonstrates the overall clinical safety of SAT and the low rate of the selection of multidrug-resistant bacteria triggered by this therapy. We also describe the composition of intestinal microbiota under the indefinite use of antibiotics for the first time.
Gen Z Switching Behaviour in Indonesia Smartphone Industry

Objective – This paper investigates the effect of satisfaction, product consumption, values on the brand commitment, and switching behaviour of Gen Z in the Indonesian smartphone industry. The study focuses on the potential of this generation as a big smartphone market in Indonesia. The behaviour of Gen Z in switching its smartphone brand is also examined. Methodology/Technique – This research evaluates the relationship between variables and their mediation using the PLS-SEM approach. A total of 944 Gen Z’s responses were collected through a face-to-face paper-based questionnaire from 4 capital cities of 4 provinces in Java Island. Findings – According to the results, satisfaction significantly influences brand switching. Product consumption value is essential in boosting commitment, an essential aspect that influences the switching of smartphone brands. Previous studies established that commitment mediates between product consumption values and brand switching behaviour. However, it has no mediation effect between satisfaction and brand switching behaviour. Novelty - This research provides new theoretical insight, specifically showing that Gen Z product consumption values and brand commitment could drive them to switch their smartphone brand. These two aspects mediate between product consumption value commitment and brand switching behaviour. Type of Paper: Empirical. JEL Classification: M30, M31, M39 Keywords: Product Consumption Values; Satisfaction; Brand Commitment; Brand Switching Behaviour; Gen Z; Smartphone Reference to this paper should be made as follows: Timotius, Prasastyo, K.W.

Enhanced P-Type GaN Conductivity by Mg Delta Doped AlGaN/GaN Superlattice Structure

A method of combining the AlGaN/GaN superlattices and Mg delta doping was proposed to achieve a high conductivity p-type GaN layer. The experimental results provided the evidence that the novel doping technique achieves superior p-conductivity. The Hall-effect measurement indicated that the hole concentration was increased by 2.06 times while the sheet resistivity was reduced by 48%. The fabricated green-yellow light-emitting diodes using the achieved high conductivity p-type GaN layer showed an 8- and 10-times enhancement of light output power and external quantum efficiency, respectively. The subsequent numerical calculation was conducted by using an Advanced Physical Model of Semiconductor Device to reveal the mechanism of enhanced device performance. This new doping technique offers an attractive solution to the p-type doping problems in wide-bandgap GaN or AlGaN materials.
A Combined Experimental and Theoretical Study on the Formation of Interstellar Propylene Oxide (CH3CHCH2O)—A Chiral Molecule

This work reveals via a combined experimental, computational, and astrochemical modeling study that racemic propylene oxide (c-C3H6O)—the first chiral molecule detected outside Earth toward the high-mass star-forming region Sagittarius B2(N)—can be synthesized by non-equilibrium reactions initiated by the effects of secondary electrons generated in the track of cosmic rays interacting with ice-coated interstellar grains through excited-state and spin-forbidden reaction pathways operating within low-temperature interstellar ices at 10 K. Our findings confront traditional hypotheses that thermal chemistries followed by processing of interstellar grains dictate the formation of complex organic molecules (COMs) in molecular clouds. Instead, we reveal a hitherto poorly quantified reaction class involving excited-state and spin-forbidden chemistry leading to racemic mixtures of COMs inside interstellar ices prior to their sublimation in star-forming regions. This fundamental production mechanism is of essential consequence in aiding our understanding of the origin and evolution of chiral molecules in the universe.
An Evaluation of Patient Satisfaction with Nursing Care: A Qualitative Study in an Indonesian Hospital

Background Patients experience first-hand quality services from nurses who are directly responsible for their welbeing. However, patient dissatisfaction with nursing services remains a problem in most developing countries. Therefore, this study aims to explore patient satisfaction with nursing care services in an Indonesian hospital. Method A qualitative study with a descriptive phenomenology method was employed. Also, in-depth interviews were conducted with 15 informants, and thematic analysis was adopted to analyze the data. Results The results of this study are described in the following themes and sub-themes: (1) hospital existence in public eyes: a) service commitment b) accessibility; (2) patients' background: a) religious aspect, b) cultural influence on perceiving health and sickness. Conclusion Hospital management needs to enhance the quality of nursing services through sustainable education programs and continuous training. These are important to improve nurses' cognition and skills, and further to ensure patient satisfaction and hospital quality.
Exact Constraint Satisfaction for Truly Seamless Parametrization

In the field of global surface parametrization a recent focus has been on so‐called seamless parametrization. This term refers to parametrization approaches which, while using an atlas of charts to enable the handling of surfaces of arbitrary topology, relate the parametrization across the cuts between charts via transition functions from special classes of transformations. This effectively makes the cuts invisible to applications which are invariant to these specific transformations in some sense. In actual implementations of these parametrization approaches, however, these restrictions are obeyed only approximately; errors stem from the tolerances of numerical solvers employed and, ultimately, from the limited accuracy of floating point arithmetic. In practice, robustness issues arise from these flaws in the seamlessness of a parametrization, no matter how small. We present a robust global algorithm that turns a given approximately seamless parametrization into an exactly seamless one ‐ that still is representable by standard floating point numbers. It supports common practically relevant additional constraints regarding boundary and feature curve alignment or isocurve connectivity, and ensures that these are likewise fulfilled exactly. This allows subsequent algorithms to operate robustly on the resulting truly seamless parametrization. We believe that the core of our method will furthermore be of benefit in a broader range of applications involving linearly constrained numerical optimization.
Serial Search of Vacant Channel in Cognitive Radio Devices with Single Radio Frequency Tranceiver

This paper derives the mean channel search time of a serial search scheme in terms of an vacant channel search using single radio frequency (RF) tranceiver. Also, it does the mean channel search time considering a penalty time due to a false alarm when the cognitive radio (CR) system operates multiple frequency channels. The numerical results suggest the optimal channel detection time using the derived mean channel search time of a serial search scheme in case of CR hardware structure with single RF path.
Androgen Receptor Immunohistochemical Expression in Undifferentiated/Dedifferentiated Endometrial Carcinoma

Uterine undifferentiated (UC)/dedifferentiated (DEAC) carcinomas are rare malignant neoplasms. They tend to pursue an aggressive clinical course with an advanced stage at presentation. It has been found that androgen receptor (AR) might play a role as a prognostic and therapeutic marker in endometrial carcinoma. However, its expression in UC/DEAC has not been investigated. Herein, the aim of this study was to evaluate the expression of AR along with estrogen receptor (ER), progestin receptor (PR), and HER2 in UC/DEAC and also in other subtypes of high-grade endometrial carcinomas. Review of our pathology database over the period of 2011 to 2019 identified 16 UC/DEAC cases (N=16). We also randomly selected other high-grade endometrial carcinomas including FIGO 3 endometrioid carcinoma (N=9), serous carcinoma (N=8), clear cell carcinoma (N=12) and carcinosarcoma (N=10) for comparison. Immunohistochemical stains for AR, ER, PR, and HER2 were performed on all 55 cases. The protein expression was evaluated both quantitatively and qualitatively. In DEAC cases both the undifferentiated component and the well-differentiated component were recorded separately. Overall, variable degrees of AR reactivity (by Allred scoring method) was present in 63% of UC/DEACs(10/16), 67% of FIGO 3 endometrioid carcinomas (6/9), 88% of serous carcinomas (7/8), 80% of carcinosarcomas (8/10), and 9% of clear cell carcinoma (1/12). AR expression was most often seen with PR (70%) or ER (60%) staining in UC/DEACs. Thirteen cases of UC/DEACs were positive for at least 1 hormone receptor. HER2 was negative in all UC/DEACs. Almost all other high-grade carcinoma cases were negative for HER2 except 20% of carcinosarcoma (2/10) and 13% of serous carcinoma (1/8) which showed 3+ HER2. Loss of AR appears to be associated with worse clinicopathologic parameters in UC/DEAC. AR is highly expressed in UC/DEAC, and in the majority of FIGO 3 endometrioid carcinomas, serous carcinomas, and carcinosarcoma. These findings suggest a potential role for androgen inhibitors in the management of patients with these tumors.
