Evolution of the yeast protein interaction network

To study the evolution of the yeast protein interaction network, we first classified yeast proteins by their evolutionary histories into isotemporal categories, then analyzed the interaction tendencies within and between the categories, and finally reconstructed the main growth path. We found that two proteins tend to interact with each other if they are in the same or similar categories, but tended to avoid each other otherwise, and that network evolution mirrors the universal tree of life. These observations suggest synergistic selection during network evolution and provide insights into the hierarchical modularity of cellular networks.
Analysis of breakdown in ferromagnetic tunnel junctions

Due to their very thin tunnel barrier layer, magnetic tunnel junctions show dielectric breakdown at voltages of the order of 1 V. At the moment of breakdown, a highly conductive short is formed in the barrier and is visible as a hot spot. The breakdown effect is investigated by means of voltage ramp experiments on a series of nominally identical Co/Al2O3/Co tunnel junctions. The results are described in terms of a voltage dependent breakdown probability, and are further analyzed within the framework of a general model for the breakdown probability in dielectric materials, within which it is assumed that at any time the breakdown probability is independent of the (possibly time-dependent) voltage that has been previously applied. The experimental data can be described by several specific forms of the voltage breakdown probability function. A comparison with the models commonly used for describing thin film SiO2 breakdown is given, as well as suggestions for future experiments.
CSAE WPS / 2005-07 The Geography of Output Volatility

This paper examines the structural determinants of output volatility in developing countries, and especially the roles of geography and institutions. We investigate the volatility effects of market access, climate variability, the geographic predisposition to trade, and various measures of institutional quality. We find an especially important role for market access: remote countries are more likely to have undiversified exports and to experience greater volatility in output growth. Our results are based on Bayesian methods that allow us to address formally the problem of model uncertainty and to examine robustness across a wide range of specifications.

Conservation and Variability of Dengue Virus Proteins: Implications for Vaccine Design

Background Genetic variation and rapid evolution are hallmarks of RNA viruses, the result of high mutation rates in RNA replication and selection of mutants that enhance viral adaptation, including the escape from host immune responses. Variability is uneven across the genome because mutations resulting in a deleterious effect on viral fitness are restricted. RNA viruses are thus marked by protein sites permissive to multiple mutations and sites critical to viral structure-function that are evolutionarily robust and highly conserved. Identification and characterization of the historical dynamics of the conserved sites have relevance to multiple applications, including potential targets for diagnosis, and prophylactic and therapeutic purposes. Methodology/Principal Findings We describe a large-scale identification and analysis of evolutionarily highly conserved amino acid sequences of the entire dengue virus (DENV) proteome, with a focus on sequences of 9 amino acids or more, and thus immune-relevant as potential T-cell determinants. DENV protein sequence data were collected from the NCBI Entrez protein database in 2005 (9,512 sequences) and again in 2007 (12,404 sequences). Forty-four (44) sequences (pan-DENV sequences), mainly those of nonstructural proteins and representing ∼15% of the DENV polyprotein length, were identical in 80% or more of all recorded DENV sequences. Of these 44 sequences, 34 (∼77%) were present in ≥95% of sequences of each DENV type, and 27 (∼61%) were conserved in other Flaviviruses. The frequencies of variants of the pan-DENV sequences were low (0 to ∼5%), as compared to variant frequencies of ∼60 to ∼85% in the non pan-DENV sequence regions. We further showed that the majority of the conserved sequences were immunologically relevant: 34 contained numerous predicted human leukocyte antigen (HLA) supertype-restricted peptide sequences, and 26 contained T-cell determinants identified by studies with HLA-transgenic mice and/or reported to be immunogenic in humans. Conclusions/Significance Forty-four (44) pan-DENV sequences of at least 9 amino acids were highly conserved and identical in 80% or more of all recorded DENV sequences, and the majority were found to be immune-relevant by their correspondence to known or putative HLA-restricted T-cell determinants. The conservation of these sequences through the entire recorded DENV genetic history supports their possible value for diagnosis, prophylactic and/or therapeutic applications. The combination of bioinformatics and experimental approaches applied herein provides a framework for large-scale and systematic analysis of conserved and variable sequences of other pathogens, in particular, for rapidly mutating viruses, such as influenza A virus and HIV.
Playing the Game: Unpacking the Rationale for Organizational Corruption in MNCs

What conditions must be present for multinational companies (MNCs) to benefit from corruption? We argue that corrupt acts by organizations can be profitable if four conditions are met: there must be an opportunity to do so, the risks must be perceived as low, the organization must be willing to engage in corruption, and it must have some skill in converting such acts into organizational advantages. We believe all of these conditions are necessary for organizational corruption to “pay off. ” We argue that these conditions would most likely be present in MNCs from corrupt environments investing in other countries rife with corruption. However, if each of the conditions must be present for the return on corruption to be sufficient, each also offers opportunities to eliminate organizational corruption.
Permanent versus determinant: not via saturations of monoids of representations

Let Det_n denote the closure of the GL_{n^2}(C)-orbit of the determinant polynomial det_n with respect to linear substitution. The highest weights (partitions) of irreducible GL_{n^2}(C)-representations occurring in the coordinate ring of Det_n form a finitely generated monoid S(Det_n). We prove that the saturation of S(Det_n) contains all partitions lambda with length at most n and size divisible by n. This implies that representation theoretic obstructions for the permanent versus determinant problem must be holes of the monoid S(Det_n).
COVER SONG IDENTIFICATION WITH IFF 0 PITCH CLASS PROFILES

The extraction of time-dependent Pitch Class Profiles (PCP) is widely used in machine listening. PCP describes effective note amplitudes at a given point in time. Our PCP extraction methodology ([1]) was originally developed for rhythm and harmony detection. It has proven very effective and is used in our free Winamp plug-in, Easy Chords. This paper describes the results of applying our PCP extraction approach to cover song identification.
Changes in serum insulin, blood sugar, and free fatty acid levels four hours after administration of human growth hormone to fasting children with short stature.

Previous studies on normal and hypopituitary adults have demonstrated that administration of human growth hormone (HGH) is associated with changes in blood sugar (BS),'free fatty acids (FFA),"4 insulin like activity (ILA),' and plasma immunoreactive insulin (IRI). ' The following investigation was carried out to study the acute effects of HGH on serum IRI, BS, and plasma FFA concentrations in normal and hypopituitary children.
On a Problem of Additive Number Theory

where all the prime factors of each A,are of a given form. A search of the literature seemed to indicate that various theorems had been conjectured but none actually proved.f For example, L. Euler stated without proof that every integer of the form 47+2 is a sum of two primes each of the form 47 + 1. Even the weaker statement that every integer of the form 4/+2 is a sum of two integers which have all their prime factors of the form 4/+1 has not yet been proved. In view of the absence of any definite results in the literature it seems worthwhile to point out that some very interesting theorems can be obtained in an elementary way. This is done in Part I of this paper and the results are summarized in Theorems 1, 2, and 3 below. In Part II we use the method of Viggo BrunJ to prove a general theorem and from this we deduce Theorems 4 and 5 below.
Oral Manifestation in Mentally Challenged Children

Background: In general, mentally challenged children have higher rates poor oral hygiene, gingivitis and periodontitis than the general population. An investigation was undertaken to assess the oral manifestations of mentally challenged children in Chennai, India. Materials and Methods: The study group consisted of 150 children (70 Down syndrome patients and 80 cerebral palsy patients). Of which, 93 patients were males and 57 were females. Results: Speech difficulty hindered the communication between the patient and the dentist. Mastication and swallowing difficulties were also present in few children. Profuse salivation was a cause for drooling of saliva down the cheeks, which was a constant finding in cerebral palsy children. The oral hygiene statuses of the patient were significantly poor. The prevalence of periodontitis was 35.7% in Down syndrome and 55.0% in cerebral palsy patients. Whereas, the prevalence of gingivitis was found to be 92.9% and 61.3% respectively. The prevalence of fractured maxillary anterior teeth was found to be more evident in cerebral palsy patients (62.9%) when compared to Down syndrome patients (0.0%). An increase in age shows an increase in the decayed-missing-filled teeth which is statistically significant. Conclusion: The prominent findings like flat nasal bridge (94.3%), hypertelorism (92.9%), high arched palate (78.6%) and fissured tongue (78.6%) in our study, suggest that they could be used as a reliable clinical markers to diagnose Down syndrome condition.
Left Atrial Anatomy Relevant to Catheter Ablation

The rapid development of interventional procedures for the treatment of arrhythmias in humans, especially the use of catheter ablation techniques, has renewed interest in cardiac anatomy. Although the substrates of atrial fibrillation (AF), its initiation and maintenance, remain to be fully elucidated, catheter ablation in the left atrium (LA) has become a common therapeutic option for patients with this arrhythmia. Using ablation catheters, various isolation lines and focal targets are created, the majority of which are based on gross anatomical, electroanatomical, and myoarchitectual patterns of the left atrial wall. Our aim was therefore to review the gross morphological and architectural features of the LA and their relations to extracardiac structures. The latter have also become relevant because extracardiac complications of AF ablation can occur, due to injuries to the phrenic and vagal plexus nerves, adjacent coronary arteries, or the esophageal wall causing devastating consequences.

Momentum and seasonality in Chinese stock markets

In this paper, we follow Jegadeesh and Titman's (1993, Journal of Finance) approach to examine 25 momentum/contrarian trading strategies using monthly stock returns in China for the period from 1994 to 2007. Our results suggest that there is no momentum profitability in any of the 25 strategies. In contrast, there is some evidence of reversal effects where the past winners become losers and past losers become winners afterward. The contrarian profit is statistically significant for the strategies using short formation and holding periods, especially for the formation periods of 1 to 3 months and the holding periods of 1 to 3 months. The contrarian strategies can generate about 12% per annum on average. Moreover, we follow Heston and Sadka (2008, Journal of Financial Economics) to investigate where there is any seasonal pattern in the cross-sectional variation of average stock returns in our momentum/contrarian strategies. There is no evidence of any seasonal pattern, and the results are robust to different formation and holding periods.
Personality of People Using Chat: An On-Line Research

Conflicting claims have been presented in the literature about on-line management of personal relationships. The current research, carried out in a substantially descriptive design, aimed to consider psychological and social features of a particular electronic environment, the Chat room. One hundred fifty-eight participants filled out an on-line questionnaire set, designed to investigate the personality traits and the prevailing interpersonal values of those participants who set up interpersonal relationships on-line. The Web research showed that, if sampling control and validity assessment were provided, it could be a valid alternative to a more traditional paper-based procedure. The results highlighted that Chat users were not an homogenous group, but were composed of different personality types. Basically, however, this specific virtual environment proved to be crowded with rather close individuals, who were looking for independence but who needed also to be supported and encouraged. They created deep on-line relationships, but these remained limited to the virtual world.
APPLYING MATK GENE FOR IDENTIFICATION OF LILIOPSIDA PLANT SPECIES FROMNORTH SULAWESI THROUGH BOLD SYSTEMS

DNA barcoding is a tool for species identification. For plant species identification, two of plastid genes (rbcL and matK) were used as standard barcodes. There are limitations of each gene marker but matK is considered to be the closest plant analogue to the CO1 animal barcode. As a mega-biodiversity country, Indonesia has many plant species used for ornamental and/or medical purposes. This study aimed to assess the identification of 15 known ornamental Liliopsida plant species in North Sulawesi using matK gene as a single marker. There were three possibilities result for species identification in this study: species level identification by top hit (1 specimen), species level identification by highest similarities (7 specimens), and genera level identification by highest similarities (7 specimens). Species identification by the highest similarity is reliable only when the result is identical with the sequence stored in the database.
Robust Extended Kalman Filtering for camera pose tracking using 2D to 3D lines correspondences

In this paper we present a new robust camera pose estimation approach based on 3D lines tracking. We used an Extended Kalman Filter (EKF) to incrementally update the camera pose in real-time. The principal contributions of our method includes first, the expansion of the RANSAC scheme in order to achieve a robust matching algorithm that associates 2D edges from the image with the 3D line segments from the input model. And second, a new framework for camera pose estimation using 2D-3D straight-lines within an EKF. Experimental results on real image sequences are presented to evaluate the performances and the feasibility of the proposed approach.

Stability and Sensitivity Analysis of Stochastic Programs with Second Order Dominance Constraints

In this paper we present stability and sensitivity analysis of a stochastic optimization problem with stochastic second order dominance constraints. We consider perturbation of the underlying probability measure in the space of regular measures equipped with pseudometric discrepancy distance ( [30]). By exploiting a result on error bound in semi-infinite programming due to Gugat [13], we show under the Slater constraint qualification that the optimal value function is Lipschitz continuous and the optimal solution set mapping is upper semicontinuous with respect to the perturbation of the probability measure. In particular, we consider the case when the probability measure is approximated by empirical probability measure and show the exponential rate of convergence of optimal solution obtained from solving the approximation problem. The analysis is extended to the stationary points when the objective function is nonconvex.
Channel Estimation and Tracking Algorithms for Harsh Vehicle to Vehicle Environments

The vehicle-to-vehicle (V2V) communication channels are highly time-varying, making reliable communication difficult. This problem is particularly challenging because the standard for V2V communication (IEEE 802.11p standard) is based on the WLAN IEEE 802.11a standard, which was designed for indoor and relatively stationary channels. In this paper, novel channel estimation and tracking algorithms for highly time varying channels are proposed. The proposed algorithms utilize the finite alphabet property of the transmitted symbol, time domain truncation, decision-directed feedback, pilot information as well as V2V channel characteristics. The proposed algorithms improve the overall system performance in terms of bit error rate, enabling the system to achieve higher data rates and larger packet lengths at high relative velocities. Simulation results show that the proposed algorithms achieve improved performance for all the V2V channel models with different velocities, and for different modulation schemes and packet sizes as compared to the conventional least squares estimator and other previously proposed channel estimation techniques for V2V channels.
High-sensitivity C-reactive protein concentrations among patients with and without diabetes in a multiethnic population of Singapore: CREDENCE Study

Objectives To determine whether high-sensitivity C-reactive protein (hs-CRP) concentrations differ between Chinese, Malays, and Indians with and without type 2 diabetes mellitus and to look for an association with demographic, metabolic and therapeutic variables. Methods Phase 1: We retrieved records of 50 Chinese, 51 Malay, and 67 Indian individuals who had routine health screening blood tests. Phase 2: We recruited 111 Chinese, 68 Malays, and 67 Indians with type 2 diabetes mellitus and measured their hs-CRP in addition to standard laboratory tests. Results Phase 1: The median hs-CRP was 0.6 mg/L (0.2–6.2) in Chinese, 1.2 mg/L (0.2–7.9) in Malays, and 1.9 mg/L (0.2–10.0) in Indians. The Indians had higher hs-CRP compared to Chinese (P < 0.05) when adjusted for age, sex, body mass index (BMI), lipids, blood pressure, and smoking, and a significant correlation was seen between female sex, smoking status, fasting glucose and triglyceride concentration, and hs-CRP in all three ethnicities. Phase 2: The median hs-CRP was 1.2 mg/L (0.2–9.9) in Chinese, 2.2 mg/L (0.2–9.0) in Malays, and 2.3 mg/L (0.2–9.8) in Indians. Indians had higher hs-CRP when compared to Chinese (P < 0.05) and a significant correlation was seen between BMI, female gender, diabetes, and the use of metformin and hs-CRP in all three ethnicities (P < 0.05) when adjusted for the above variables and use of aspirin, angiotensin-converting enzyme inhibitor/angiotensin receptor blockers (ACE-I/ARB), statin, metformin, rosiglitazone, sulfonylurea, glinides, acarbose, and insulin. Conclusion hs-CRP concentrations are significantly higher in Indians compared to the Chinese (in both the diabetic and nondiabetic individuals) after adjustment for the various demographic, metabolic, and therapeutic variables.
Modeling of Individual and Organizational Factors Affecting Traumatic Occupational Injuries Based on the Structural Equation Modeling: A Case Study in Large Construction Industries

Background Individual and organizational factors are the factors influencing traumatic occupational injuries. Objectives The aim of the present study was the short path analysis of the severity of occupational injuries based on individual and organizational factors. Materials and Methods The present cross-sectional analytical study was implemented on traumatic occupational injuries within a ten-year timeframe in 13 large Iranian construction industries. Modeling and data analysis were done using the structural equation modeling (SEM) approach and the IBM SPSS AMOS statistical software version 22.0, respectively. Results The mean age and working experience of the injured workers were 28.03 ± 5.33 and 4.53 ± 3.82 years, respectively. The portions of construction and installation activities of traumatic occupational injuries were 64.4% and 18.1%, respectively. The SEM findings showed that the individual, organizational and accident type factors significantly were considered as effective factors on occupational injuries’ severity (P < 0.05). Conclusions Path analysis of occupational injuries based on the SEM reveals that individual and organizational factors and their indicator variables are very influential on the severity of traumatic occupational injuries. So, these should be considered to reduce occupational accidents’ severity in large construction industries.
Adoption of RFID and its Long Term Impact on Firm Value

With the growing scale of RFID investment, the relationship between RFID and firm value has attracted the attention of a lot of researchers. Prior research had employed the event study method to examine the short term market reaction to RFID adoption and found significant negative abnormal return. In this paper, we extend previous research by investigating the long term impact of RFID investment on firm market value using the CPA (Calendar Portfolio Analysis), 108 announcements related to 74 publicly traded companies were analysed. Our results indicate an overall significant negative impact on long term abnormal return of market value after adoption of RFID. It is also discovered that non-US based firms, late adopters, manufacturers, highly diversified firms, high financially unhealthy firms and low growth potential firms suffered more negative impact in the long term. The results signify that the market is impacted by the risks associated with the use of a new and disruptive technology like RFID and may not yet be ready to accept it as a standard technology that is adopted by firms. Put together, our results provide new insights into how RFID and other contextual factors interact to affect the financial performance of firms in the long run.
