Structural analysis of RNA polymerase - helicase complexes by chemical cross-linking and mass spectrometry

Information about dynamics and interactions within multi-protein complexes are essential to understand biological processes. Unfortunately, high-resolution structure determination techniques i.e. X-ray crystallography and NMR are often not applicable to these macromolecular complexes. Chemical cross-linking of protein complexes coupled to mass spectrometry (CXMS) of peptides is a technique that can provide spatial amino acid distance constraints imposed by the length of the spacer of the cross-linking agent, to obtain low resolution (10-30 Å) structural information. However, in particular the low abundance of crosslinked peptides makes this approach analytically challenging. In Chapter 4, we have developed an approach enhancing the efficiency of CXMS. In this chapter, the usefulness of the approach was further demonstrated by mapping several cross-links between bacterial RNA polymerases (RNAPs) and interacting proteins. The interaction between the helicase UvrD and RNAP from E. coli was revealed by 10 cross-linked peptides. Seven cross-links, combined with other evidence about the interaction of the orthologuous B. subtilis helicase PcrA to RNAP indicates a binding site for UvrD on the upstream face of RNAP. The same binding site is used by Mfd, a helicase that dislocates stalled RNAP from the template upon transcription-coupled repair. This may imply similar roles of UvrD and Mfd during transcription. UvrD/PcrA may dislodge RNAP from the template to enable DNA replication upon collision with a replication fork. Three other RNAP-UvrD cross-links suggest an alternative binding interaction on the downstream face. One cross-link between B. subtilis RNAP and HelD was also detected on the downstream site of RNAP. Helicases at the downstream face may either remove DNA binding proteins that otherwise might prevent RNAP elongation, or dislocate RNAP upon transcript termination or upon replication-transcription collisions. We also identified a cross-link between RPOE, also called δ subunit of RNAP, and the β' clamp region of RNAP, suggesting how δ can compete with the binding of DNA. This work has demonstrated the use of our CXMS approach to obtain novel information about the bacterial transcription process. *This work was done in collaborations with Prof. Evgeny Nudler, Medical center, NewYork University, (E. coli-UvrD) and Dr. Peter Lewis, Newcastle University, (B. subtilis-PcrA).
EVALUATION OF A RADAR HYDROMETEOR CLASSIFIER BY COMPARISON WITH IN SITU AIRCRAFT DATA

Intensive research over the last few decades with meteorological radars having a polarimetric capability has led to an emerging capability for identifying hydrometeor types remotely. Such work began with efforts to discriminate between hail and rain (e.g. Barge 1974); Jameson and Johnson (1990) summarize the early work. Several algorithms for inferring hydrometeor types from radar data have been developed (e.g. Höller et al. 1994; Matrosov et al. 1996; Vivekanandan et al. 1999; Zrnić and Ryzhkov 1999; Liu and Chandrasekar 2000; Straka et al. 2000). Most are based on calculations of the scattering properties of idealized model hydrometeors with limited comparisons with in situ observations of the particles. Like all remote sensing techniques, these algorithms need to be evaluated against extensive sets of in situ observations to validate and improve them. The work reported here examines samples of coordinated aircraft microphysics and polarimetric radar data from the Severe Storms Electrification and Precipitation Study (STEPS), a study of summer convective storms in the High Plains region of the U.S.A.
Changing Nutritional Composition of Pomegranate ( Punica granatum L . ) Seed by Aspergillus niger Solid State Fermentation to Making Suitable for Poultry Nutrition

Nutritional changes in pomegranate (Punica granatum L.) seed by Aspergillus niger solid state fermentation were investigated in this study. Pomegranate seed was fermented by two different A. niger strains (ATCC 20345 and ATCC 9142). Crude protein, ether extract and ash were increased (P<0.001), nitrogen-free extract, crude fiber, neutral detergent fiber and acid detergent fiber were decreased (P<0.001) by fermentation in both strains. Hemicellulose was not changed (P>0.05) by ATCC 20345 but decreased (P<0.01) by ATCC 9142. This results showed that A. niger solid state fermentation can be used to improve nutritional composition of pomegranate seed in order to make a suitable feedstuff for poultry nutrition.
Sci Fiscal Decentralization and Economic Growth in South Asian Countries

Fiscal decentralization in south Asian region is taken up as tool to settle economic inefficiencies. The reliance of present study is to locate for the fact that either it is true in case of such economies. To do so, non-stationary panel data analyses was used for the period from 1990 to 2016. Empirical findings backed at panel pooled mean group of Auto Regressive Distributed Lag came along with the findings that expenditure and revenue decentralization had significant positive and negative effects on economic growth. Similarly, gross fixed capital formation and foreign direct investment were found to have significant positive effect on the economic growth of selected South Asian economies. For short run, the diagnostics showed positive follow-ups of economic growth in response to education decentralization, however, revenue decentralization was traced for negative spell-outs on economic growth. Policy implications are underlined for increasing revenue decentralization for meeting the goal of economic growth.
PERFORMANCE MEASUREMENTS AND HUMAN BEHAVIOUR ON E-COMMERCE SYSTEMS ♦

E-commerce on the Internet is becoming an efficient economic model. This technology provides business organizations with useful systems to trade their products. Therefore, there is a great interest to adapt these applications to user behaviour. Benchmark tools can provide information about the performance of these systems. However, these benchmark tools simulate a specified environment, usually very tied with a specific kind of application, what means that obtained results can only be discussed in such environments. As it is reflected in a study we have performed, it is quite difficult to describe consumer behaviour completely, but there are certain circumstances in which some consumer patterns can be identified. Thus, this information could be used to develop better benchmark tools, which provide more accurate results to real user behaviours.
I . Frequency II . Serial Position Curve III . Visual Statistical Learning IV . Cognitive Model

In domains where users are exposed to large variations in visuo-spatial features among designs, they often spend excess time searching for common elements (features) in familiar locations. This paper contributes computational approaches to restructuring layouts such that features on a new, unvisited interface can be found quicker. We explore four concepts of familiarisation, inspired by the human visual system (HVS), to automatically generate a familiar design for each user. Given a history of previously visited interfaces, we restructure the spatial layout of the new (unseen) interface with the goal of making its elements more easily found. Familiariser is a browser-based implementation that automatically restructures webpage layouts based on the visual history of the user. Our evaluation with users provides first evidence favouring familiarisation.
A Metropolis-Hastings Sampling of Subtrees in Graphs

This article presents two methods to sample uniform subtrees from graphs using Metropolis-Hastings algorithms. One method is an independent Metropolis-Hastings and the other one is a type of add-and-delete MCMC. In addition to the theoretical contributions, we present simulation studies which confirm the theoretical convergence results on our methods by monitoring the convergence of our Markov chains to the equilibrium distribution.
A Review of Image-Based Modelling Techniques

This paper presents a categorisation of image-based modelling (IBM) algorithms based on their approach to the IBM problem. This categorisation groups the algorithms into three classes, surface reduction, depth map and sparse point algorithms. We then cover a further four key considerations or aspects related to choosing and designing an IBM algorithm, scene type, prior information, type of features and similarity measures. Finally the paper presents an implementation of an IBM algorithm based on the previous discussion and shows some simulation results using data from the Middlebury website www.middlebury. edu/stereo.
EFFICIENT HIGH FREQUENCY SINGLE-PHASE AC CHOPPER

The paper introduces and analyzes a new single-phase ac chopper circuit with 100 kHz switching frequency. The adequate functioning and high performance of the circuit (the efficiency and the waveform of the absorbed input current and load voltage) were tested both by simulation and experimentally. Beside this wide application range, the converter size and weight are reduced, it is more efficient, responds faster in automatic control applications and the waveforms of the current supplied by the grid and of the output voltages are nearly sinusoidal.
Accounting for the stochastic nature of sound symbolism using Maximum Entropy model¹

: Sound symbolism refers to stochastic and systematic associations between sounds and meanings. Sound symbolism has not received much serious attention in the generative phonology literature, perhaps because most if not all sound symbolic patterns are probabilistic. Building on the recent proposal to analyze sound symbolic patterns within a formal phonological framework (Alderete and Kochetov 2017), this paper shows that MaxEnt grammars allow us to model stochastic sound symbolic patterns in a very natural way. The analyses presented in the paper show that sound symbolic relationships can be modeled in the same way that we model phonological patterns. We suggest that there is nothing fundamental that prohibits formal phonologists from analyzing sound symbolic patterns, and that studying sound symbolism using a formal framework may open up a new, interesting research domain. The current study also reports two hitherto unnoticed cases of sound symbolism, thereby expanding the empirical scope of sound symbolic patterns in natural languages.
Security Analysis of Digital Signature Scheme with Message Recovery using Self-Certified Public Keys

Tseng and his colleagues have proposed two variants of authenticated encryption scheme using self-certified public keys. Their schemes have two fundamental properties. Only the intended receiver can recover the message while verifying the signature, and each user can use his own private key independently without system authority learning about it. This paper presents man-in-the-middle attacks to both Tseng and his colleagues authenticated encryption variants. It will be shown that these schemes are not secure against this attack.
Effect of Microgravity on Most Frequently Isolated Microorganisms from Cosmetics

Microorganisms associated with commonly used cosmetics and effects of microgravity on most frequently isolated microorganism were investigated. The microorganisms isolated from the cosmetics were Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Bacillus cereus, Proteus vulgaris, Bacillus subtilis, Trichoderma piluliferum and Neocosmospora vasinfecta. Fifty percent of the cosmetics were contaminated with Staphylococcus aureus, 31.82% contaminated with Pseudomonas aeruginosa, 22.73% contaminated with Escherichia coli, 13.64% contaminated with Proteus mirabilis, 13.64% contaminated with Bacillus cereus, 9.09% contaminated with Proteus vulgaris, 4.55% contaminated with Bacillus subtilis, 13.64% contaminated with Trichoderma piluliferum and 9.09% contaminated with Neocosmospora vasinfecta. The S. aureus which was the most frequently isolated bacteria was subjected to microgravity condition. The antibiotics susceptibility test of the most frequent bacteria (S. aureus) was investigated and it was observed that the S. aureus grown under stimulated microgravity condition exhibited resistance to antibiotic more than S. aureus grown under earth gravity. The most frequently isolated bacteria namely S. aureus exhibited greater resistance to antibiotics under stimulated microgravity condition than one under earth gravity condition at different time. The resistance of the S. aureus to antibiotics tends to increase with increased in revolution per minutes (rpm) at which the bacterium was subjected.
The Real Effects of Tax Avoidance

This paper investigates the impact of tax avoidance on financing and investment decisions by firms. Tax avoidance, by decreasing expenses, may positively affect investment, but at the same time may also increase opacity, which can aggravate financing constraints. We build a simple theory to analyze the firm’s choice of tax avoidance and investment in the presence of financing constraints. The model predicts that if the opacity cost of tax avoidance outweighs the benefit of a reduced tax burden, then investment and investment-cash flow sensitivity may go down due to these tightened financial constraints. To test these predictions, we exploit the differential exposure to a stark change in tax avoidance opportunities caused by entity classification rules in 1997 (so called Check-the-Box regulations) for firms that have foreign subsidiaries in place, versus firms that do not. Constrained firms do not increase investment and show no changes in leverage, but experience lower credit ratings and rating downgrades, and become more financially constrained. Additionally, their investmentcash flow sensitivity declines. These results are primarily driven by firms with low institutional ownership. These findings are inconsistent with the general notion that tax avoidance may alleviate financing constraints and promote investment.
Pacific-Rim Conference on Multimedia 2013 Cross-Codebook Image Classification

Representing images by bag of visual codes (BoVC) features has been the cornerstone of state-of-the-art image classification system. Since the BoVC features depend on a precomputed codebook in use, when the codebook applied to test images differs from the codebook of an existing image classification system, the system becomes inapplicable. To resolve the codebook incompatibility problem, we propose in this paper cross-codebook image classification. This is achieved by transforming BoVC features derived from one codebook to make them compatible with another codebook. Two BoVC transform methods, i.e., codereassignment and least squares, are studied. Experiments on a popular image classification benchmark set show that both methods are better than random guess when crossing the codebooks. In particular, when the BoVC features are transformed from a higher dimension to a relatively small dimension, cross-codebook image classification has a similar performance compared to within-codebook image classification, with a relative performance loss of 1.3% only. The results justify the feasibility of the proposed cross-codebook image classification.
Wedding-Planning Industry in Indonesia: The Influence of Technology Orientation and Trust as Mediating Factors on the Relationship between Entrepreneurial Orientation and e-Commerce Adoption

Statistical data has shown that there is a decrease in the number of marriages in Jakarta in the period 2009-2014 with no significant changes in the last 3 years. The millennial generation of brides and grooms are characterized by their adoption of technology and electronic transactions. This research aimed to examine the influence of technology orientation and trust as mediating variables on the correlation between entrepreneurial orientation and intention to adopt the e-commerce platform. The findings suggested that trust factor plays a more important role than technology orientation.
Study on the Influence of Airgun Excitation Conditions on Airgun Signals and Travel Time Variation Measurements 1

Because of the different excitation conditions of the airgun sourceꎬ there will be subtle differences in airgun signals. Travel time variation of airgun signals often mix into source information which can̓t fully reflect the evolution of the medium. This article uses the airgun signals from the Binchuan Transmitting Seismic Station to analyze the airgun signal′s characteristics of phase and correlation. We conducted a comparative analysis of the effects of the pair difference method and the deconvolution method on eliminating the influence of the excitation conditions in travel time variation. The results show that: (1) The pressure pulse and its subsequent wave of airgun source wavelet are less affected by excitation conditions that we can use it to obtain high ̄precision excitation moments. (2) Deconvolution can improve the correlation of the airgun signal. (3) The pair difference method can̓t eliminate the influence of excitation conditions in travel time variation. Deconvolution can reduce excitation condition interference and the influence of the excitation condition in the travel time variation after deconvolution of the vertical signal is significantly reduced.
LIGUSTRUM VULGARE L . : IN VITRO FREE RADICAL SCAVENGING ACTIVITY AND PRO-OXIDANT PROPERTIES IN HUMAN COLON CANCER CELL LINES

Ligustrum vulgare L. is a semi-evergreen woody branched bush from the family Oleaceae, widespread and frequently used in traditional medicine and pharmacy for treating different diseases. The aim of this study was to determine phenolic and flavonoid contents in L. vulgare leaf and fruit methanolic extracts, its free radical scavenging potential and in vitro effects on pro-oxidant/antioxidant status of human colon cancer cells (HCT-116 and SW480). The total phenolic content and DPPH free radical scavenging activity, concentration of superoxide anion radical (O2 .), nitrites and reduced glutathione (GSH) in HCT 116 and SW480 cells were determined spectrophotometricaly. Inducible nitric oxide synthase (iNOS) protein expression was determined by imunoflorescence. Higher concentration of phenolic compounds and flavonoids was observed in leaf in comparison to fruit extracts. Both leaf and fruit extracts had considerably high ability for free radical scavenging by DPPH. The obtained results indicated that L. vulgare extracts increased O2 . -
Authenticated LSM Trees with Minimal Trust Yuzhe ( Richard )

In the age of user-generated contents, the workloads imposed on information-security infrastructures become increasingly write intensive. However, existing security protocols, specifically authenticated data structures (ADSs), are historically designed based on update-in-place data structures and incur overhead when serving write-intensive workloads. In this work, we present LPAD (Log-structured Persistent Authenticated Directory), a new ADS protocol designed uniquely based on the log-structure merge trees (LSM trees) which recently gain popularity in the design of modern storage systems. On the write path, LPAD supports streaming, non-interactive updates with constant proof from trusted data owners. On the read path, LPAD supports point queries over the dynamic dataset with a polynomial proof. The key to enable this efficiency is a verifiable reorganization operation, called verifiable merge, in LPAD. Verifiable merge is secured by the execution in an enclave of trusted execution environments (TEE). To minimize the trusted computing base (TCB), LPAD places the code related to verifiable merge in enclave, and nothing else. Our implementation of LPAD on Google LevelDB codebase and on Intel SGX shows that the TCB is reduced by 20 times: The enclave size of LPAD is one thousand code lines out of more than twenty thousands code lines of a vanilla LevelDB. Under the YCSB workloads, LPAD improves the performance by an order of magnitude comparing with that of existing update-in-place ADSs.
Evaluation of the Antimicrobial Activity , Starter Capability and Technological Properties of Some Probiotic Bacteria Isolated from Egyptian Pickles

The work employed in this paper was an endeavour to select and characterise a probiotic bacterial strains which could be used as starter and protective cultures for pickles fermentation. Sixty one bacterial isolates were isolated from Egyptian pickled vegetables and fruits onto both MRS and nutrient agar media. One isolate only of lactic acid bacteria growing on MRS agar: LPS10 and three isolates BPS4, BPS20 and BPS33 growing on nutrient agar inhibited other pathogenic and non-pathogenic bacteria. Additionally the LPS10 isolate inhibited Candida albicans fungus. The antimicrobial spectrum of LPS10 isolate was more than that obtained from other BPS4, BPS20 and BPS33 isolates. The LPS10 bactic acid bacterial isolate showed fast growth and decreased pH of the medium from 6.5 to 3.5 within 48 h, tolerated NaCl up to 11%, grew at wide range of pH (2.0-8.0) and temperatures (1544C). It showed interested probiotic capabilities such as production of acetoin, citrate utilization, oxalate hydrolysis and production of some important enzymes. The BPS4, BPS20 and BPS33 isolates grew in nutrient broth, at 4-7% NaCl; at initial pH 3.5-8.0; at 15C-50C, they produced acetoin and decomposed some polymers and consequently, could be used as probiotics and biocontrol agents during pickles fermentation. The bacterial isolates LPS10; BPS4; BPS20; BPS33 were identified by biochemical and molecular methods as belonging to L. plantarum LPS10’ B. acidicolaBPS4; B. amyloliquefaciens BPS20; B. mycoidesBPS33 respectively.
