SCI-GA: Software Component Identification using Genetic Algorithm

Identifying software components is a crucial task in software development. There are a number of methods to identify components in the literature; however, the majority of these methods rely on clustering techniques with expert judgment. In contrast to the previous methods, which have used classical clustering techniques, this paper maps the components identification problem to an optimization problem. We propose a novel GA-based algorithm (Genetic Algorithm) as a powerful optimization search algorithm, called SCI-GA (Software Component Identification using Genetic Algorithm), to identify components from analysis models. SCI-GA uses software cohesion, coupling, and complexity measurements to define its fitness function. For performance evaluation, we evaluated SCI-GA using three real-world cases. The results reveal that SCI-GA can identify correct suboptimal software components, and performs far better than alternative heuristics like k-means and FCA-Based methods.
Types of discourse and textual construction of knowledge

- Assuming that language plays a main role in the development of the individual throughout life, the aim of this paper is to re ﬂ ect on the mechanisms which upgrade the textual and linguistic construction of knowledge. To do this, I have chosen the Socio-Discursive Interactionism (SDI) theoretical and epistemological perspective. I will focus speci ﬁ cally on the analysis of the mental operations that underlie the forms of knowledge organization and the way these operations are linguistically and textually formed. Based on the positioning of Benveniste, Weinrich and Genette, such operations in the SDI framework are named as types of discourse and are related to two discursive domains: narrating (the temporal coordinates of language action match those verbalised in the text) and exposing (the two coordinates have no match between them). Using a qualitative and interpretative method, the textual analysis will focus on two memorialistic texts, produced in different contexts: (i) Memórias da minha vida (Memoirs of my life), an unpublished text, written by João Azenha when he was 76/77 years old, between 2006 and 2007, limited to household activity; (ii) As pequenas memórias (The small memories), a text written by José Saramago, in the context of literary and household activities and published in Portugal in 2006 by Caminho. Its aims are to analyse the speci ﬁ c linguistic con ﬁ gurations of the discourse types in texts which adopt the textual genre memoirs and analyse the way the discourse types link to the different types of reasoning. This work will enable us to achieve two conclusions. The ﬁ rst is that, in the case of the memoirs genre, the types of discourse take on particular aspects at the level of geneologically determined linguistic units. The second is that the types of reasoning, being indissociable from the discourse types, in the memories genre, are informed not only by formal logic, but also by practical and experiential knowledge.
Human resource oriented antecedents to post-adoption technology performance

This study investigated the influence of human resource oriented antecedents to user perceptions toward the performance capabilities of a new logistics information tracking technology. Willingness to take risks, job relevance, trialability and technology trust were evaluated as antecedents to technology performance. The research examined the effect of these constructs on technology acceptance as a function of post-adoption perceptions of technology performance. A research model was developed and tested based in Rogers’ (2003) Innovation Diffusion Theory. Data from a mail survey were collected from 224 first-tier supply chain users of the technology. Structural equation modelling was used to test six hypothesized relationships for significance, direction, and intensity. The findings indicate that: (a) willingness to take risks and job relevance affect technology trust and technology performance; and, (b) trialability affects perceptions of technology performance. The results of this study advance our understanding of post-adoption perceptions of supply chain affiliates and offer suggestions for enhancing user perceptions of technology performance. Implications from this study along with suggestions for future research are provided.
IEEE TRANSACTIONS ON INFORMATION THEORY , VOL . ? ? , NO . ? ? , ? ? ? ? ? ? 1 Online Regularized Classification Algorithms

This paper considers online classification learning algorithms based on regularization schemes in reproducing kernel Hilbert spaces associated with general convex loss functions. A novel capacity independent approach is presented. It verifies the strong convergence of the algorithm under a very weak assumption of the step sizes and yields satisfactory convergence rates for polynomially decaying step sizes. Explicit learning rates with respect to the misclassification error are given in terms of the choice of step sizes and the regularization parameter (depending on the sample size). Error bounds associated with the hinge loss, the least square loss, and the support vector machineq-norm loss are presented to illustrate our method.
Leisure and life satisfaction among Tai Chi and public square dance participants in Hong Kong

Leisure and Life Satisfaction among Tai Chi and Public Square Dance Participants in Hong Kong by YAO Yechen Master of Philosophy Public Square Dance, or Guang Chang Wu (GCW) is a form of group dance that originated from Mainland China and has emerged gradually in Hong Kong. Like the more traditional Tai Chi, GCW is popular among the middle-aged and older adults, and is carried out in public spaces. However, the two activities seem to be treated quite differently by both government authorities and the general public. The study aims to compare the physiological, social and psychological benefits of the two forms of exercise. It also seeks to explore whether and how social determinants affect people’s choice to participate in either Tai Chi or GCW. 189 Tai Chi and 188 GCW participants were surveyed. Binary logistic regression, MANOVA and univariate ANOVA were used for data analysis. It is shown that age, gender, birthplace, employment, residence, as well as people’s leisure attitude, all influence the likelihood that someone participates in Tai Chi or GCW. On the other hand, the effects on well-being, social inclusion, social network and life satisfaction are similar between Tai Chi and GCW participants, though the two groups differ in terms of their opinions on leisure satisfaction and utilisation of public space. As GCW is largely an unsanctioned activity in Hong Kong, policy makers should acknowledge the advantages of GCW activity, and adopt measures that regulate GCW participation in Hong Kong. This is not only one of the early studies focused on the cultural differences between Mainland immigrants and natives in Hong Kong, it also has important implications for future research in leisure, gender, ageing and cultural studies.
Transmitter and Precoding Order Optimization for Nonlinear Downlink Beamforming

The downlink of a multiple-input multiple output (MIMO) broadcast channel (BC) is considered, where each receiver is equipped with a single antenna and the transmitter performs nonlinear Dirty-Paper Coding (DPC). We present an efficient algorithm that finds the optimum transmit filters and power allocation as well as the optimum precoding order(s) possibly affording time-sharing between individual DPC orders. Subsequently necessary and sufficient conditions for the optimality of an arbitrary precoding order are derived. Based on these we propose a suboptimal algorithm showing excellent performance and having low complexity.
Ieee Transactions on Information Theory Analysis of Regularized Ls Reconstruction and Random Matrix Ensembles in Compressed Sensing

—Performance of regularized least-squares estimation in noisy compressed sensing is analyzed in the limit when the dimensions of the measurement matrix grow large. The sensing matrix is considered to be from a class of random ensembles that encloses as special cases standard Gaussian, row-orthogonal, geometric and so-called T-orthogonal constructions. Source vectors that have non-uniform sparsity are included in the system model. Regularization based on 1-norm and leading to LASSO estimation, or basis pursuit denoising, is given the main emphasis in the analysis. Extensions to 2-norm and " zero-norm " regularization are also briefly discussed. The analysis is carried out using the replica method in conjunction with some novel matrix integration results. Numerical experiments for LASSO are provided to verify the accuracy of the analytical results. The numerical experiments show that for noisy compressed sensing, the standard Gaussian ensemble is a suboptimal choice for the measurement matrix. Orthogonal constructions provide a superior performance in all considered scenarios and are easier to implement in practical applications. It is also discovered that for non-uniform sparsity patterns the T-orthogonal matrices can further improve the mean square error behavior of the reconstruction when the noise level is not too high. However, as the additive noise becomes more prominent in the system, the simple row-orthogonal measurement matrix appears to be the best choice out of the considered ensembles.
A Simple DFT-aided Spatial Basis Expansion Model and Channel Estimation Strategy for Massive MIMO Systems

This paper proposes a new transmission strategy for the multiuser massive multiple-input multiple-output (MIMO) systems, including uplink/downlink channel estimation and user scheduling for data transmission. A discrete Fourier transform (DFT) aided spatial basis expansion model (SBEM) is first introduced to represent the uplink/downlink channels with much few parameter dimensions by exploiting angle reciprocity and the physical characteristics of the uniform linear array (ULA). With SBEM, both uplink and downlink channel estimation of multiuser can be carried out with very few amount of training resources, which significantly reduces the training overhead and feedback cost. Meanwhile, the pilot contamination problem in the uplink raining is immediately relieved by exploiting the spatial information of users. To enhance the spectral efficiency and to fully utilize the spatial resources, we also design a greedy user scheduling scheme during the data transmission period. Compared to existing low-rank models, the newly proposed SBEM offers an alternative for channel acquisition without need of channel statistics for both TDD and FDD systems based on the angle reciprocity. Moreover, the proposed method can be efficiently deployed by the fast Fourier transform (FFT). Various numerical results are provided to corroborate the proposed studies.
Automatic Test Data Generation Tool Based on Genetic Simulated Annealing Algorithm

This paper presents an automatic test data generation tool that aims at generating test data dynamically by reducing the problem of test data generation to one minimizing function. The tool is composed of three parts: program instrumentation module; test path generation module and test case generation module. In order to enhance the computational efficiency, we makes some improvements on the encoding, crossover probability and annealing gene of the genetic simulated annealing algorithm (GASS), and then use the results to generate the test data on the program instrumentation. Experimental results show this approach has better effect.
Validating Spatial Augmented Reality for interactive rapid prototyping

This paper investigates the use of Spatial Augmented Reality in the prototyping of new human-machine interfaces, such as control panels or car dashboards. The prototyping system uses projectors to present the visual appearance of controls onto a mock-up of a product. Finger tracking is employed to allow real-time interactions with the controls. This technology can be used to quickly and inexpensively create and evaluate interface prototypes for devices. In the past, evaluating a prototype involved constructing a physical model of the device with working components such as buttons. We have conducted a user study to compare these two methods of prototyping and to validate the use of spatial augmented reality for rapid iterative interface prototyping. Participants of the study were required to press pairs of buttons in sequence and interaction times were measured. The results indicate that while slower, users can interact naturally with projected control panels.
Mesenchymal stem cells in corneal neovascularization: Comparison of different application routes

The purpose of the present study is to investigate the effect of mesenchymal stem cells in corneal neovascularization and wound healing, and to compare the effectiveness of two possible application routes, subconjunctival injection and amniotic membrane transplantation. Chemical injury was induced by application of sodium hydroxide to the rats' corneas. After 7 days, the animals were divided into three groups. Different treatment methods were used for each group as follows: i) Group 1, injection of bone marrow-derived mesenchymal stem cells (BMSCs) under the conjunctiva; ii) group 2, transplantation of amniotic membranes, previously seeded with BMSCs; and iii) group 3, the untreated control group. The eyes were examined using a slit lamp on a weekly basis. After 4 weeks, the animals were sacrificed and corneas were removed for further examination. Corneal flat mounts were made following ink perfusion for improved vessel visualization, image capturing and quantitative evaluation. enzyme-linked immunosorbent assay was performed to detect the levels of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 9 (MMP-9). Reverse transcription-quantitative polymerase chain reaction was used for detection of VEGF-A, MMP-9, Toll-like receptor (TLR)2 and TLR4 gene expression levels. Cryosections were used for histological examination and immunostaining. Statistical analysis (Welch's one-way analysis of variance) demonstrated a significant difference between the groups [P≤0.05, confidence interval (CI) 95%]. The level of injury in group 1 was significantly different from groups 2 and 3. Measurement of the vessel area and VEGF gene expression levels had a similar difference among the groups (P≤0.05, CI 95%), however the differences for TLR2 and TLR4 were not statistically significant. BMSCs were previously transduced with the green fluorescent protein gene by lentivirus to track the movement of the cells following transplantation. The transplanted cells enhanced corneal wound healing by trophic factor production and immune-regulatory effect, rather than by direct transdifferentiation into corneal cells. The results of the current study demonstrated that BMSCs enhance corneal wound healing and decrease the area of neovascularization. Furthermore, the comparison of two application routes indicated that single subconjunctival injection appeared more effective than transplantation with amniotic membrane.
Preserving the bits of the Danish Internet

One of the many challenges in large-scale web archiving is long-time preservation of the amounts of data generated by the harvester. We describe the bit preservation solution chosen by Netarkivet. We then define a programmatic, probabilistic model of hardware failures and repair operations in the solution. The mean time to failure of this model is then computed in a number of experiments based on simulation.
MEG evidence for conceptual combination but not numeral quantification in the left anterior temporal lobe during language production

The left anterior temporal lobe (LATL) has risen as a leading candidate for a brain locus of composition in language; yet the computational details of its function are unknown. Although most literature discusses it as a combinatory region in very general terms, it has also been proposed to reflect the more specific function of conceptual combination, which in the classic use of this term mainly pertains to the combination of open class words with obvious conceptual contributions. We aimed to distinguish between these two possibilities by contrasting plural nouns in contexts where they were either preceded by a color modifier (“red cups”), eliciting conceptual combination, or by a number word (“two cups”), eliciting numeral quantification but no conceptual combination. This contrast was chosen because within a production task, it allows the manipulation of composition type while keeping the physical stimulus constant: a display of two red cups can be named as “two cups” or “red cups” depending on the task instruction. These utterances were compared to productions of two-word number and color lists, intended as non-combinatory control conditions. Magnetoencephalography activity was recorded during the planning for production, prior to motion artifacts. As expected on the basis of comprehension studies, color modification elicited increased LATL activity as compared to color lists, demonstrating that this basic combinatory effect is strongly crossmodal. However, numeral quantification did not elicit a parallel effect, suggesting that the function of the LATL is (i) semantic and not syntactic (given that both color modification and numeral quantification involve syntactic composition) and (ii) corresponds more closely to the classical psychological notion of conceptual combination as opposed to a more general semantic combinatory function.
Clinical Distinct Features of Noncardiac Chest Pain in Young Patients

Background/Aims Noncardiac chest pain (NCCP) is a very common disorder world-wide and gastroesophageal reflux disease (GERD) is known to be the most common cause. The prevalence of NCCP may tend to decrease with increasing age. However, there is little report about young aged NCCP. The aim of this study was to examine the prevalence of GERD and to evaluate the efficacy of proton pump inhibitor (PPI) test in the young NCCP patients. Methods Thirty patients with at least weekly NCCP less than 40 years were enrolled. The baseline symptoms were assessed using a daily symptom diary for 14 days. Esophago-gastro-duodenoscopy (EGD) and 24 hr esophageal pH monitoring were performed for the diagnosis of GERD and esophageal manometry was done. Then, patients were tried with lansoprazole 30 mg twice daily for 14 days, considering positive if a symptom score improved ≥ 50% compared to the baseline. Results Nine (30%) of the patients were diagnosed with GERD at EGD and/or 24 hr esophageal pH monitoring, also, 3 (10%) were diagnosed with GERD-associated esophageal motility disorder and 3 (10%) were non GERD-associated. Concerning PPI test, GERD-related NCCP had a higher positive PPI test (n = 8, 89%) than non GERD-related NCCP (n = 5, 24%) (p = 0.002). Conclusions In young patients with NCCP, a prevalence of GERD diagnosed using EGD and/or 24 hr esophageal pH monitoring was 30%. PPI test was very predictable on diagnosis of GERD-related NCCP, thus, PPI test in young NCCP patients may assist to the physician's clinical judgment of NCCP.
Epigenetic Regulation of Bovine Spermatogenic Cell-Specific Gene Boule

Non-primate mammals have two deleted azoospermia (DAZ) family genes, DAZL and Boule; genes in this family encode RNA-binding proteins essential for male fertility in diverse animals. Testicular DAZL transcription is regulated by epigenetic factors such as DNA methylation. However, nothing is known about the epigenetic regulation of Boule. Here, we explored the role of DNA methylation in the regulation of the bovine Boule (bBoule) gene. We found that a long CpG island (CGI) in the bBoule promoter was hypermethylated in the testes of cattle-yak hybrids with low bBoule expression, whereas cattle had relatively low methylation levels (P < 0.01), and there was no difference in the methylation level in the short CGI of the gene body between cattle and cattle-yak hybrids (P > 0.05). We identified a 107 bp proximal core promoter region of bBoule. Intriguingly, the differences in the methylation level between cattle and cattle-yak hybrids were larger in the core promoter than outside the core promoter. An in vitro methylation assay showed that the core promoter activity of bBoule decreased significantly after M.SssI methylase treatment (P < 0.01). We also observed dramatically increased bBoule transcription in bovine mammary epithelial cells (BMECs) after treatment with the methyltransferase inhibitor 5-Aza-dC. Taken together, our results establish that methylation status of the core promoter might be involved in testicular bBoule transcription, and may provide new insight into the epigenetic regulation of DAZ family genes and clinical insights regarding male infertility.
Bilingual language interference initiates error detection: Evidence from language intrusions*

In the current study, we investigated bilingual error detection by measuring the repair rate of language intrusions (i.e., involuntary production of nontarget language words) that arose while bilinguals produced sentences in a language switching context. This allowed us to compare two prominent accounts of error detection in a bilingual setting. According to the conflict monitoring account, error detection is initiated by interference. Since language switching increases bilingual language interference, error detection should be better in switch relative to repetition trials. According to the perceptual loop theory, error detection is based on language comprehension. Since language switching is known to impair language comprehension, it follows that error detection should be worse in switch relative to repetition trials. The results showed that the repair rate of language intrusions was higher in switch than repetition trials, thus providing evidence that bilingual language interference instigates error detection, in line with the conflict monitoring account.
Consent Issues in Genetic Research: Views of Research Participants

Background: With the arrival of large-scale population-based genomic research studies, such as the Precision Medicine Initiative (PMI), the question of how to best consent participants is significant, and in an era of patient-centered research, few studies have evaluated participants' preferences about re-consent and broad consent. Using quantitative methods, this study evaluates participants' views regarding the acceptability of re-consent and broad consent in subjects from the Participant Issues Project. Methods: A total of 450 participants were recruited from a cancer genetics registry, including cancer patients, their relatives, and controls. Participants completed a secure online survey. Results: Most participants endorsed re-consent when investigating an unrelated health condition or sharing their de-identified data with an investigator at a different institution. Notification rather than re-consent was preferred when studying a different gene but the same disease. Over 80% of respondents endorsed re-consent when parents of a child gave the original consent and the child has now reached adulthood. Preferences for some scenarios varied by history of cancer at baseline, gender, stage of cancer, or case versus control group. The large majority of participants preferred the option to select broad consent categories of research. Conclusion: Understanding research participants' preferences, including their views on the need for re-consent, are critical to the success of the PMI.
