CTP and parS coordinate ParB partition complex dynamics and ParA-ATPase activation for ParABS-mediated DNA partitioning

ParABS partition systems, comprising the centromere-like DNA sequence parS, the parS-binding ParB-CTPase and the nucleoid-binding ParA-ATPase, ensure faithful segregation of bacterial chromosomes and low-copy-number plasmids. F-plasmid partition complexes containing ParBF and parSF move by generating and following a local concentration gradient of nucleoid-bound ParAF. However, the process through which ParBF activates ParAF-ATPase has not been defined. We studied CTP- and parSF-modulated ParAF—ParBF complex assembly, in which DNA-bound ParAF-ATP dimers are activated for ATP hydrolysis by interacting with two ParBF N-terminal domains. CTP or parSF enhances the ATPase rate without significantly accelerating ParAF—ParBF complex assembly. Together, parSF and CTP accelerate ParAF—ParBF assembly without further significant increase in ATPase rate. Magnetic-tweezers experiments showed that CTP promotes multiple ParBF loading onto parSF-containing DNA, generating condensed partition complex-like assemblies. We propose that ParBF in the partition complex adopts a conformation that enhances ParBF—ParBF and ParAF—ParBF interactions promoting efficient partitioning.
Reducing Regression Test Suites using the Word2Vec Natural Language Processing Tool

Continuous integration in software development requires to run the tests on a regular basis to ensure that the code does not regress. So that the execution time of the regression test suite remains reasonable its size must be reduced while preserving its fault detection capability. From test execution logs, we extract from each test a trace, which is a sequence of events. We then consider each event as a word, and apply natural language processing methods, here the Word2Vec tool, to detect similarities in sentences, and partition them into clusters. We thus can reduce the regression test suite by removing redundant tests. We present the approach on a small case study, and we use mutation based testing to assess the effectiveness of the reduction.
Social Robots in Cognitive Interventions. Advances, Problems and Perspectives

Social Assistive Robots are being used in therapeutic interventions for elderly people affected by cognitive impairments. The present paper reports our research lines aiming at investigating the role of a social robot in aiding therapists during cognitive stimulation sessions for elders withMild Cognitive Impairment and Mild Dementia. We review our studies whose results show that social robots have been positively accepted by the seniors in different experiments. Participants were very attentive and involved in the sessions’ tasks and their experience was mainly positive. Our data suggest that this technology can be a valid tool to support psychotherapists in cognitive stimulation interventions emphasizing the need of multidisciplinary approaches combining assessment of behavior and robotics.

Root Morphology, Proton Release, and Carboxylate Exudation in Lupin in Response to Phosphorus Deficiency

ABSTRACT Narrow-leafed lupin (Lupinus angustifolius L.) is widely planted in infertile acidic soils where phosphorus (P) deficiency is one of the major limiting factors for plant growth. A hydroponic experiment was conducted to examine the morphological and physiological responses of roots of narrow-leafed lupin in response to altered P supply at 0, 1, 10, 25 or 75 μ M P as monopotassium phosphate (KH2PO4). Low P (P0 and P1) significantly decreased the plant biomass, but the supply of 10 μ M P was sufficient to produce similar plant biomass as the maximal P supply (P75), indicating an efficient P acquisition by narrow-leafed lupin. Phosphorus deficiency did not enhance rates of carboxylate exudation and proton release by plant roots, indicating that carboxylate exudation and proton release are not the mechanisms for efficient P acquisition. In contrast, low P supply evidently modified the root morphology by increasing the primary root elongation, and developing a large number of cluster-like first-order lateral roots with dense root hairs, thus allowing efficient P acquisition by narrow-leafed lupin under low P supply.
Tangible Interaction as a resource for Relational HCI

In this paper, we propose to delineate the emerging field of Relational HCI coming from the domains of assistive technologies and community technologies. We briefly describe our work on the relational design of an interactive map for visually impaired people and then outline three principles which characterize this new HCI perspective. We conclude on the very potential of TUIs to develop this relational perspective of HCI
Crafting Tangible Interactions. Can thinking through craftsmanship values enrich the design process of TI?

While today the digital is ubiquitous and many interaction designers focus on designing manual or digital processes faster, more precise, ascribed, repeatable and replicable, there is a robust counterposing standpoint looking for site-specific, volatile and unique interactions. Craftsmanship is a practice that today is still trying to negotiate its role between technology, the digital, and handmaking values within the Design realm. This workshop suggests that looking closely at craftsmanship practices and unpacking the values craft practitioners hold over materiality, techniques, and processes could enrich our knowledge on human-values. The nuances these values hold provide useful insights that could be used when designing future tangible interactions.
Semantics-driven Keyword Search over Knowledge Graphs

With the continuous growth of data represented as knowledge graphs, advanced access techniques are in great demand. Keyword search is a convenient and simple method to retrieve information. It can be used as an alternative to structured query languages, since it does not require technical expertise. In the context of knowledge graphs, keyword search aims to ﬁnd candidate subgraphs that connect the query keywords and thus answer user queries. Eﬃciently ﬁnding candidates and ranking them eﬀectively is still a challenging task. The goal of this work is to automatically ﬁnd appropriate subgraphs. The focus is particularly on enhancing the accuracy of subgraph ranking by leveraging semantic information combined with other factors. Preliminary results demonstrate that the combination of importance-based and semantics-based metrics is promising compared to purely structural techniques.
Case Report of Treatment of Secondary Airway Stenosis after Thulium Laser Ventilation

A 10-year-old boy presented with symptoms of dyspnea. 3 monthspreviously, he had received a tracheostomymechanical ventilation because of trauma and had been dilated tracheal stenosis 4 times at previous hospital.We performed bronchoscopy and found a reduction of the upper trachea that is below subglottic 2 cm, diameterof 4mm, length of 1cm due to the web-likefibrotic stenosis. Thilium fiber laser via flexible bronchoscopy wasused to explode the stenotic lesion. His condition was improved well afer 3 months re examination. Thiliumfiber laser is a valuable tool with potential for therapy of an endobronchial obstructing airway lesion.
Towards tunable resistivity–strain behavior through construction of oriented and selectively distributed conductive networks in conductive polymer composites

The resistivity–strain behavior of conductive polymer composites (CPCs) has gained intense interest due to its importance for various applications. The resistivity of CPCs often increases substantially and linearly under strain. To achieve constant resistivity under strain, a large filler content and special network configuration are often required. And a tunable step-wise resistivity–strain behavior has yet to be reported. Herein, a new method combining polymer blends and pre-stretching is introduced to modify the resistivity–strain behavior of CPCs based on thermoplastic polyurethane (TPU)/polyolefin elastomer (POE) with multi-walled carbon nanotubes (MWCNTs) selectively incorporated in the TPU phase. Depending on the compositions of blends and the intensity of pre-stretching, various interesting resistivity–strain behaviors have been achieved. The resistivity can be either linearly increasing or constant. Interestingly, two-stepwise resistivity–strain behavior has been achieved, with first an increase then a constant value. To understand this unique phenomenon, the phase morphology and conductive network structure are systematically characterized. It is observed that the orientation of MWCNTs is strongly correlated with overall resistivity. Finally, a mechanism involving fibrillization and “slippage” between conductive phases is proposed to explain the resistivity–strain dependency. This study provides guidelines for the preparation of high performance strain sensors as well as stretchable conductors.
Density-Functional Theory Study of Electronic and Structural Properties of Doped Polypyrroles

Electronic and structural properties of polypyrroles oxidized by different concentrations of chlorine atoms or molecules are studied with the use of a density functional method implemented with plane waves and pseudo-potentials for the core electrons. The calculated properties are compared with those obtained for the neutral system that are in good agreement with the available experimental data. The role of the counterion in the oxidation process is studied extensively and shown to be crucial for the localization of charge and structural defects.
New Bidirectional Dc – Dc Converter Topology For Renewable Sources D

This paper presents a new resonant dual active bridge (DAB) topology, which uses a tuned inductor–capacitor–inductor (LCL) network. In comparison to conventional DAB topologies, the proposed topology significantly reduces the bridge currents, lowering both conduction and switching losses and the VA rating associated with the bridges. The performance of the DAB is investigated using a mathematical model under various operating conditions.
The Relationship Between Outbound and Inbound Communication in Government-to-Citizen Interaction

While many citizens have adopted digital channels for public service interaction, the use of traditional channels remains high, preventing economic benefits from digitalization. The channel choice (CC) and multi-channel management (MCM) fields of echoice of channels and the management of service interactions across channels. Research has mostly focused on either the citizen or organizational side and single channel communication. visits) is understudied. Therefore, we present a longitudinal quantitative study, which analyzes channel traffic data from two service areas, pensions, and parental leave, across three channels (letters, telephone calls, website visits). We apply interactivity theory and the concept of multiplexity to guide our analysis. We seek to offer contributions to the CC and MCM literature by demonstrating a relationship between outbound and inbound communication and the multiplex nature of government-citizen interaction.
129Xe and 1H NMR Study of the Reversible Trapping of Xenon by Cryptophane-A in Organic Solution

The interaction of xenon with cryptophane-A in 1,1,2,2-tetrachloroethane-d2 is investigated by 129Xe and 1H NMR spectroscopy. Xenon is reversibly trapped into the cavity of this host to form a 1 to 1 host−guest complex with an apparent association constant K of the order of at least 3 × 103 M-1 at 278 K. The exchange between the free and bound xenon is slow on the 129Xe NMR time scale, and the bound xenon resonance is shifted by approximately 160 ppm to lower frequencies with respect to the free xenon resonance. The xenon complex is at least 4 and 20 times more stable, respectively, than the corresponding chloroform and methane complexes under the same conditions. The stability of this xenon complex appears to be much greater than that of the previously described xenon complex of α-cyclodextrin in water. This is probably due to the combination of three favorable effects: (i) good size matching between the guest and the cryptophane cavity in its most relaxed conformation, resulting in the optimization of .
Design of binary weighted DAC for asynchronous ADC with improved slew rate and with calibrated size of capacitors

This work proposed a binary-weighted Digital-to-Analog Converter (DAC), which is designed to be used in Asynchronous successive approximation register (SAR) based Analog-todigital converters (ADCs) specifically and in other relevant operations . The design has yielded an improved slew rate, and it is less prone to noise as the size of capacitors is taken in accordance with KT/C noise calculation. For achieving all mentioned goals, and to restrict the size of DAC, within suitable dimensions charge scaling DACs are used. One more advantage of this design is its accuracy, further it does not require op-Amps for its operation. Results of statistical simulation and mathematical consideration are published which depicts the supremacy of the design. A highresolution DAC designed for this specific purpose has to have special consideration for the effect of local mismatch, parasitic and matching of the capacitors, for that, the common-centroid approach has been followed. This design has displayed a high resolution with small unit capacitances and that too without expensive factory calibration.
Assessment of Machine Learning of Optimal Solutions for Robotic Walking

— The generation of optimal solutions for robotic bipedal walking using whole-body dynamics is well known to have a big computational cost, preventing online trajectory generation for optimal control methods that satisfy Pontryagin's Principle and its Conditions of Optimality. However, bipedal walking has fundamental kinematic and dynamic characteristics that shape different solutions for different parameters in similar curves. Such characteristics were previously defined in biomechanical literature as movement primitives. Recently, studies generated parametrized optimal solutions by performing regressions from training data into movement primitives using Machine Learning. The learned solutions were very close to the actual optimal solution. This study evaluates the precision of such strategy by optimizing the gait of a 6 degrees of freedom planar robot using different Cost Functions, in order to understand if the precision of Machine Learning in recreating optimal solutions is impacted by what is being optimized. 
Low-Temperature Pyrolysis and Gasification of Biomass: Numerical Evaluation of the Process Intensification Potential of Rotating- and Circulating Rotating Fluidized Beds in a Static Fluidization Chamber

The process intensification potential of rotating- and circulating rotating fluidized beds in a static fluidization chamber when used for the low-temperature pyrolysis and gasification of biomass is numerically evaluated. The species continuity equations and energy balance equations are based on complete mixing for the particles within given zones of the particle bed and plug flow for the gas. The reaction mechanism accounts for pyrolysis of biomass and tar, gas-phase combustion, the water gas shift reaction, and combustion and gasification of char. A comparison with current circulating fluidized bed riser technology is made. The circulation of inert solid with a high heat capacity and the separation of the flue gas from the production gas are also studied.
Human Eosinophils Can Express the Cytokines Tumor Necrosis Factor-a and Macrophage Inflammatory Protein-la

By in situ hybridization, 44-100% of the blood eosinophils from five patients with hypereosinophilia and four normal subjects exhibited intense hybridization signals for TNF-a mRNA. TNF-a protein was detectable by immunohistochemistry in blood eosinophils of hypereosinophilic subjects, and purified blood eosinophils from three atopic donors exhibited cyclohex-imide-inhibitable spontaneous release ofTNF-a in vitro. Many blood eosinophils (39-91%) from hypereosinophilic donors exhibited intense labeling for macrophage inflammatory protein-la (MIP-la) mRNA, whereas eosinophils of normal donors demonstrated only weak or undetectable hybridization signals for MIP-la mRNA. Most tissue eosinophils infiltrating nasal polyps were strongly positive for both TNF-a and MIP-la mRNA. By Northern blot analysis, highly enriched blood eosinophils from a patient with the idiopathic hypereosinophilic syndrome exhibited differential expression of TNF-a and MIP-la mRNA. These findings indicate that human eosinophils represent a potential source of TNF-a and MIP-la, that levels of expression of mRNA for both cytokines are high in the blood eosinophils of hypereosinophilic donors and in eosinophils infiltrating nasal polyps, that the eosinophils of normal subjects express higher levels of TNF-a than MIP-la mRNA, and that eosinophils purified from the blood of atopic donors can release TNF-a in vitro.

The aqueous extract of chamomile gave complete inhibition against the fungus Trichophyton rubrum at (20,25,30) mg/ml under temperatures of (25,50,75,100)°C While, the aqueous extract of chamomile gave complete inhibition against the fungus Aspergillus fumigatus at concentrations (25,30) mg/ml under the temperature degree of (75,100) °C.
Evaluating Soil Quality for Some Soils of South East El- Qantara

The governmental strategy aims tothe reclamation and cultivation of about 400.000 feddans concentrated mainly in El-Tina Plain (50.000 feddans), South East El-Qantara (75.000 feddans), Rabaa (70.000 feddans), Bir El-Abd (70.000 feddans) and El-Serw and El-Qawarir (135.000 feddans) areas. The current study revealed the variation in soil fertility status of soils developed on various landforms in the area as the soils were having low to high in organic carbon (1.4 to 21. 5 mg kg)and having low available nitrogen (4.32 to 58.30mg kg); low to abundant phosphorus (2.06 to 59.23mg kg) and deficient to adequate in available K (23.50to 1360mg kg) contents. The result showed the value of soil fertility quality index (SFQI) ranging from 0.022381to 0.665533with an average 0.310947. When fertility quality of the studied soils was examined (according to SFQI); only 27.692% of the soils has very low fertility quality, about 40.00% of the soils has Low, about 28.462% of the soils has moderate and 3.846 % has good fertility quality. The soil fertility quality index, easier to compute with fewer parameters, can be used as a quick tool to evaluate soil quality and to measure changes occurring after using different management practices. This study suggests that using soil fertility quality index to evaluate agricultural soil fertility quality can provide similar results even when different indicator methods and models have been used in the study area. In this study, SFQI determined to be the most accurate method for evaluation of soil fertility quality, because it took all soil parameters into consideration and gave the most consistent results. We suggest using the SFQI to evaluate agricultural soil fertility quality for desert soils because of its highest correlation with economic yield of desert soils.
The Effect of Customer Satisfaction Mediation for the Relationship Between Service Quality and Customer Loyalty

The economic sustainability of a hotel can be determined by its service quality, satisfaction, and customer loyalty. The level of customer satisfaction can be increased if the hotel offers good quality service, and this can retain customer loyalty. This research aims to study the influence of service quality on customer loyalty and test the mediation effect of customer satisfaction on this relationship for the rooms division of hotels in Dili, Timor-Leste. Respondents for this research were hotel customers, and the research questionnaire adopted items from previous research. SMART-PLS 3.0 was used to test the hypothesis. The findings show that service quality and customer satisfaction do not significantly influence customer loyalty. Moreover, customer satisfaction does not mediate the relationship between service quality and customer loyalty. This research contributes to the theory of service quality, customer satisfaction, and customer loyalty. At a practical level, this research can help hotel managers develop strategies to retain their customers through improved service quality. This research also provides data to government on the level of customer satisfaction of hotels in Timor-Leste. This data can be used to develop the government’s human capital training policy so that service quality in hotels and other service industries can be improved.
Quantitative characterization of the local electrophilicity of organic molecules. Understanding the regioselectivity on Diels-Alder reactions

Regional electrophilicity at the active sites of the reagents involved in polar Diels−Alder processes may be described on a quantitative basis using an extension of the global electrophilicity index recently introduced by Parr et al. (J. Am. Chem. Soc. 1999, 121, 1922). The local or regional electrophilicity provides useful clues about the expected regioselectivity of the products on Diels−Alder reactions showing significant polar character. The local (regional) electrophilicity index shows significant advantages over other unnormalized definitions of relative electrophilicity proposed in the literature in the sense that it clearly identifies the relevant electrophilic sites in a molecule without restricting the search to those sites having comparable values of regional electrophilic/nucleophilic softness.
