Abstract:

The aim of this study was to determine the effects of 38% silver diamine fluoride (SDF) on carious lesions of human deciduous teeth. Ten extracted deciduous incisors with caries were collected and treated with SDF. After the treatment, the teeth were sectioned through the center of the carious lesion. The extent of sliver precipitation was examined using quantitative backscattered electron scanning electron microscopy (qBSE-SEM), energy-dispersive X-ray spectroscopy (EDX), and micro-computed tomography (micro-CT). The qBSE-SEM images revealed that the silver particles could penetrate through the pellicle complex, along with the rod sheaths into the demineralized enamel rods and the dentinal tubules, and form silver-enriched barriers surrounding the carious lesions at depths up to 2,490.2 μm (mean 744.7 ± 448.7 μm) within the dentinal tubules of the carious lesions, but less likely in the sound enamel. The EDX spectrum analysis revealed that carbon, oxygen, phosphorus, chlorine, silver, and calcium were the main elements detected in the lesions treated with SDF. Additionally, sodium, magnesium, aluminum, silicon, zinc, sulfur, and fluorine were detected as the minor elements within the SDF precipitation “zone.” The micro-CT analysis further showed that in the deep cavitated lesions, the silver precipitation could be observed in the pulp chamber. These findings provide new evidence defining the SDF mode of action for arresting caries and suggest that the application of a highly concentrated SDF solution on deciduous teeth should be used with caution for various carious lesions.

Abstract:

Previous studies have suggested that the mandible may be more influenced by mechanical loading than by circulating hormone levels. We tested the hypothesis that hypofunction has a greater influence than ovariectomy on mandibular bone. Two-month-old rats were ovariectomized (OVX) or had maxillary molars removed from one side to induce unilateral mandibular hypofunction. Control animals remained untreated. After 5 months, animals were killed, and bones were assessed by micro-tomography (μCT), quantitative back-scattered electron analysis in an SEM (qBSE-SEM), and light microscopy. Mineralization density was reduced in calvarial, maxillary, and mandibular alveolar bone following OVX, yet was increased in lingual mandibular alveolar bone of the hypo-function animals compared with controls. OVX caused a reduction in osteocyte density in alveolar bone, while hypofunction showed an increase compared with controls. Hypofunction led to alveolar bone becoming more highly mineralized and more cellular, while ovariectomy caused a reduction in both mineralization density and osteocyte numbers.

Abstract:

Due to the high cost of the qubit generating device (QGD) (the single photon source), QGD may not be available at the same time in both communicating parties (Alice and Bob) who have to execute the quantum bit string commitment (QBSC) protocol for some application environments. All the existing QBSC protocols allow one-way commitment i.e., only the party (Bob) who possesses the QGD is allowed to commit a bit string to Alice who does not have the QGD, but not the other way around. However, what happens if Alice, who does not have the QGD, is required to commit a bit string to Bob? The current QBSC protocols fail to provide a solution in this case. Therefore, the purpose of this paper is to allow Alice, who is not equipped with the QGD, to commit a bit string to Bob who has the QGD. With our proposed protocol, together with previously proposed QBSC protocols, Alice and Bob can perform two-way commitment, even though Bob is the only party who is equipped with the QGD.

Abstract:

Spectra of quantum beats (QBs) of nuclear resonant forward scattering contain the interference information of all allowed energy transitions of a nucleus, which makes it complicated to extract hyperfine structure directly. Here, we propose a new method, based upon the extraction of prime beat components, to understand QBs. In this method, the origin of major spectral lines in the Fourier Transformation of QBs is studied, and the energy levels of hyperfine structure are obtained directly from the QBs. We applied this method to the temperature dependent QBs of hematite. The Morin temperature and hyperfine structure obtained by this method are in consistent with that by conventional Mössbauer spectroscopy (MS). It serves to interpret the components of QBs of nuclear resonant forward scattering as simple as the conventional (MS).

Abstract:

AbstractThe tropical Madden–Julian oscillation (MJO) excites a northward propagating Rossby wave train that largely determines the extratropical surface weather consequences of the MJO. Previous work has demonstrated a significant influence of the tropospheric El Niño–Southern Oscillation (ENSO) on the characteristics of this wave train. Here, composite analyses of ERA-Interim sea level pressure (SLP) and surface air temperature (SAT) data during the extended northern winter season are performed to investigate the additional role of stratospheric forcings [the quasi-biennial oscillation (QBO) and the 11-yr solar cycle] in modifying the wave train and its consequences. MJO phase composites of 20–100-day filtered data for the two QBO phases show that, similar to the cool phase of ENSO, the easterly phase of the QBO (QBOE) produces a stronger wave train and associated modulation of SLP and SAT anomalies. In particular, during MJO phases 5–7, positive SLP and negative SAT anomalies in the North Atlantic/Eurasian sector are enhanced during QBOE relative to the westerly phase of the QBO (QBOW). The opposite occurs during the earliest MJO phases. SAT anomalies over eastern North America are also more strongly modulated during QBOE. Although less certain because of the short data record, there is some evidence that the minimum phase of the solar cycle (SMIN) produces a similar increased modulation of SLP and SAT anomalies. The strongest modulations of SLP and SAT anomalies are produced when two or more of the forcings are superposed (e.g., QBOE/cool ENSO, SMIN/QBOE, etc.).

Abstract:

Purpose: To evaluate a simple method for quantification of focal activity in bone scintigraphy (BS). Material and Methods: The gamma camera was calibrated using a phantom. Quantitative bone scintigraphy (QBS) was performed on 11 men recently diagnosed with prostate cancer (PCa), for whom routine BS showed involvement of the skeleton. Following endocrine therapy for 4 to 8 months, a second QBS was performed. Changes in QBS values were then compared to changes in serum levels of prostate-specific antigen (PSA). Results: PSA response indicating regression of PCa was accompanied by a decrease in the QBS value in 8 of the 11 patients. The overall mean error of the QBS values was 15%. Conclusion: QBS according to this method is a relatively simple procedure that might contribute to objective evaluation of therapeutic effects in skeletal metastases, although its validity must be tested in a larger clinical material.

Abstract:

Per identificare precocemente una stenosi della fistola arterovenosa (FAV) prima che evolva in trombosi, è necessario un programma di sorveglianza utilizzando il monitoraggio della portata. Rispetto alle protesi, però, nelle FAV native i valori soglia di portata, la frequenza del monitoraggio e il rapporto costo/beneficio non sono chiaramente definiti. Infatti, la misurazione mensile della portata della FAV in tutti i pazienti risulta improponibile nella maggior parte dei Centri di Emodialisi. Inoltre, per quanto riguarda la FAV autoioga, non è sempre possibile applicare le metodiche considerate gold standard e la valutazione clinico-anamnestica, pur indispensabile, non risulta sufficiente. Il QB Stress Test (QBST), un nuovo test di screening, è un valido strumento per individuare solo le FAV con portata ridotta: infatti, ha una buona correlazione con le misurazioni della portata ottenute con la diluizione a ultrasuoni. I pazienti con QBST positivo hanno una portata più bassa di quelli con QBST negativo (433 ± 203 vs 1168 ± 681 mi/min, p

Abstract:

Abstract Type 2 diabetes mellitus (T2DM) is a major public health concern requiring engagement with specific self-care activities for improvement. Due to the increased risk for neuropathy, foot ulcers, and infections, engagement with certain footcare practices (e.g., inspecting feet and inside shoes, washing and drying between toes) is an important part of overall diabetes self-care. However, interventions targeting blood glucose monitoring, medication management, nutrition, and/or physical activity often precede footcare interventions. Question-Behavior Effects (QBEs), which describe the effects of behavior questioning on future engagement in that behavior, provide a unique framework for studying diabetes self-care. Although clinicians may not administer footcare interventions for people with T2DM, footcare behaviors are often still assessed (e.g., through questionnaires) in session and, consistent with QBEs, may improve through the repetition of questioning. The present study evaluated footcare QBEs (specifically, the number of days of foot inspection and cleaning in the past week) across 7 sessions of an at-home diabetes management program without intentional footcare intervention. Paired-samples t-tests (N = 78, ages 40-88 years) revealed significant improvements in the number of days of foot inspection and cleaning from intake to session 1 and intake to session 5. However, from intake to session 7, only significant improvements in foot inspection were detected. These findings reflect the potency of footcare QBEs in the absence of specific footcare interventions. They also reveal differential engagement in foot inspection and cleaning after an extended period of questioning, suggesting certain diabetes self-care behaviors may taper without the intentional introduction of intervention.

Abstract:

Abstract Wave–mean flow interactions associated with the Holton–Tan effect (HTE), whereby the tropical quasi-biennial oscillation (QBO) modulates the Northern Hemisphere wintertime stratospheric polar vortex, are studied using the ERA-Interim dataset. Significant evidence of the HTE in isentropic coordinates is found, with a weaker and warmer polar vortex present when the lower-stratospheric QBO is in its easterly phase (QBOe). For the first time, the authors quantify the QBO modulation of wave propagation, wave–mean flow interaction, and wave decay/growth via a calculation of potential vorticity (PV)-based measures, the zonal-mean momentum budget, and up-/downgradient eddy PV fluxes. The effect of the tropospheric subtropical jet on QBO modulation of the wave activity is also investigated. In the subtropical-to-midlatitude lower stratosphere, QBOe is associated with an enhanced upward flux of wave activity, and corresponding wave convergence and wave growth, which leads to a stronger poleward zonal-mean meridional circulation and consequently a warmer polar region. In the middle stratosphere, QBOe is associated with increased poleward wave propagation, leading to enhanced wave convergence and in situ wave growth at high latitudes and contributing to the weaker polar vortex. In agreement with recent studies, the results suggest that the critical-line effect cannot fully account for these wave anomalies associated with the HTE. Instead, it is suggestive of a new, additional mechanism that hinges on the QBO-induced meridional circulation effect on the latitudinal positioning of the subtropical jet. Under QBOe, the QBO-induced meridional circulation causes a poleward shift of the subtropical jet, encouraging more waves to propagate into the stratosphere at midlatitudes.

Abstract:

BackgroundA national programme of health checks to identify risk of cardiovascular disease (CVD) is being rolled out but is encountering difficulties because of low uptake.ObjectiveTo evaluate the effectiveness of an enhanced invitation method using the question–behaviour effect (QBE), with or without the offer of a financial incentive to return the QBE questionnaire, at increasing the uptake of health checks. The research went on to evaluate the reasons for the low uptake of invitations and compare the case mix for invited and opportunistic health checks.DesignThree-arm randomised trial and cohort study.ParticipantsAll participants invited for a health check from 18 general practices. Individual participants were randomised.Interventions(1) Standard health check invitation only; (2) QBE questionnaire followed by a standard invitation; and (3) QBE questionnaire with offer of a financial incentive to return the questionnaire, followed by a standard invitation.Main outcome measuresThe primary outcome was completion of the health check within 6 months of invitation. Ap-value of 0.0167 was used for significance. In the cohort study of all health checks completed during the study period, the case mix was compared for participants responding to invitations and those receiving ‘opportunistic’ health checks. Participants were not aware that several types of invitation were in use. The research team were blind to trial arm allocation at outcome data extraction.ResultsIn total, 12,459 participants were included in the trial and health check uptake was evaluated for 12,052 participants for whom outcome data were collected. Health check uptake was as follows: standard invitation, 590 out of 4095 (14.41%); QBE questionnaire, 630 out of 3988 (15.80%); QBE questionnaire and financial incentive, 629 out of 3969 (15.85%). The increase in uptake associated with the QBE questionnaire was 1.43% [95% confidence interval (CI) –0.12% to 2.97%;p = 0.070] and the increase in uptake associated with the QBE questionnaire and offer of financial incentive was 1.52% (95% CI –0.03% to 3.07%;p = 0.054). The difference in uptake associated with the offer of an incentive to return the QBE questionnaire was –0.01% (95% CI –1.59% to 1.58%;p = 0.995). During the study period, 58% of health check cardiovascular risk assessments did not follow a trial invitation. People who received an ‘opportunistic’ health check had greater odds of a ≥ 10% CVD risk than those who received an invited health check (adjusted odds ratio 1.70, 95% CI 1.45 to 1.99;p < 0.001).ConclusionsUptake of a health check following an invitation letter is low and is not increased through an enhanced invitation method using the QBE. The offer of a £5 incentive did not increase the rate of return of the QBE questionnaire. A high proportion of all health checks are performed opportunistically and not in response to a standard invitation letter. Participants receiving opportunistic checks are at higher risk of CVD than those responding to standard invitations. Future research should aim to increase the accessibility of preventative medical interventions to increase uptake. Research should also explore the wider use of electronic health records in delivering efficient trials.Trial registrationCurrent Controlled Trials ISRCTN42856343.FundingThis project was funded by the NIHR Health Technology Assessment programme and will be published in full inHealth Technology Assessment; Vol. 20, No. 84.

Abstract:

One of the most important promises of the move to an SQL-based accounting software package has been that it frees the accountant from the necessity of resorting to a programmer when retrieving information from the organization's database in response to unanticipated managerial needs. That promise is founded, in part, on the availability of a very high-level, visual relational query language interface known as Query By Example (QBE). Unfortunately, the implementation of QBE in Microsoft Access 2000 fails to support users in formulating complex queries involving set comparison that tend to arise in on-line analytical processing (OLAP) situations. And, while Paradoxs implementation of QBE makes the formulation of such queries quite intuitive, its built-in SQL translation feature fails to provide a clue on how to convert such queries into SQL. This paper presents a systematic approach based on formulating complex set queries in Paradoxs richer QBE notation and translating them into SQL queries that can be handled by Access 2000.

Abstract:

BackgroundPeritoneal metastasis from pancreatic cancer (PM-PC) may be treated with repeated pressurised intraperitoneal aerosol chemotherapy (PIPAC). Utility of next-generation sequencing (NGS) to detect cancer-related mutations in peritoneal quadrant biopsies (QBs) and peritoneal fluid (PF) after systemic and PIPAC treatment has not been evaluated. Around 90% of pancreatic cancers (PCs) harbour a KRAS mutation, making PC ideal for the evaluation of this aspect.AimsEvaluation of PM-PC in terms of (1) histological response to PIPAC using Peritoneal Regression Grading Score (PRGS), (2) clinical characteristics and (3) frequency of mutations in QBs and PF before and after PIPAC.MethodsPeritoneal QBs and PF were obtained prior to each PIPAC. NGS for 22 cancer-related genes was performed on primary tumours, QBs and PFs. Response was assessed by the four-tiered PRGS.ResultsSixteen patients treated with a median of three PIPAC procedures were included. The mean PRGS was reduced from 1.91 to 1.58 (p=0.02). Fifty-seven specimens (13 primary tumours, 2 metastatic lymph nodes, 16 PFs and 26 QB sets) were analysed with NGS. KRAS mutation was found in 14/16 patients (87.50%) and in QBs, primary tumours and PF in 8/12 (66.67%), 8/13 (61.53%) and 6/9 (66.67%). The median overall survival was 9.9 months (SE 1.5, 95% CI 4.9 to 13.9).ConclusionPIPAC induces histological response in the majority of patients with PM-PC. KRAS mutation can be found in PM-PC after PIPAC at a frequency similar to the primaries. NGS may be used to detect predictive mutations in PM-PC of various origins, also when only post-PIPAC QBs or PFs are available.

Abstract:

The purpose of the study was to compare cytotoxicity of two Quillaja saponaria bark saponin (QBS) mixtures against two lung cell lines: normal MRC-5 fibroblast cell line and tumor A-549 epithelial cells of lungs’ alveoli. The study, performed both at a macro-scale and in a dedicated microfluidic device, showed that QBS was more toxic to the cell line more abundant in cholesterol (MRC-5). The QBS mixture with higher saponin fraction was found to be more cytotoxic towards both cell lines. The results may help to better understand the cytotoxicity of saponin-rich herbal medicines towards normal and tumor cells depending on their cholesterol content.

Abstract:

The findings of a recent study on the procurement of professional architectural and engineering (A/E) services in New York City are outlined in an attempt to evaluate some of the claims put forward by proponents and opponents of qualifications-based selection (QBS) of such services. QBS is a federally mandated requirement enacted by the U.S. Congress in 1972, in recognition of the need for improvements in the way in which professional A/E services are procured. The law, commonly referred to as the "Brooks Act," requires that architects and engineers be selected on the basis of their professional qualifications and subject to negotiation of a fair and reasonable compensation of such services. New York State is one of the states that adopted QBS (a total of 41 states had adopted it as of the end of 2001); but the New York State law does not cover local jurisdictions, and New York City continues to use competitive pricing as its primary method of selecting A/E contractors, citing the numerous advantages of the current system as well as the disadvantages of the proposed QBS method. The present study was based on past literature as well as recently procured projects in New York City (1997 to 1999), as presented by the New York City Mayor’s Office of Contracts during a public hearing on QBS (December 1999).

The exploration capability of the bacterial swarm is improved in this paper using quorum sensing and the anti-predatory activity. The performance of the proposed QBSO method is verified for optimality, practicability, convergence and robustness on a 5, 10-unit system. Furthermore, a practical south Indian 20-thermal generating units with recorded load demand profiles of three different weather situations. The numerical dispatch result indicates that the presented technique finds the minimized generating cost and consistently progresses the computational time. The presented technique outperforms the Bacterial Swarm Optimization (BSO) and the previous presented methods.

ABSTRACT Introduction Monitoring training loads, along with the recovery status, is important for preventing unwanted adaptations. Knowledge of these variables over volleyball seasons is still scarce. Objective To monitor and describe the training load and recovery status of volleyball players over a competitive season. Methods The sample consisted of 14 professional volleyball players. For the entire season, the training load was monitored daily by the SPE method during the session, and the recovery status was monitored by TQR and QBE on the first and last days of training for the week. Results There was a decrease in training load between Preparatory Period I and Competitive Period I (p = 0.03), followed by an increase in Preparatory Period II (p <0.001) and a new decrease in Competitive Periods II (p = 0.01 ) and III (p = 0.003). There was a significant reduction between Pre-TQR and QBE and Post-TQR and QBE in all mesocycles. In the Pre-TQR, there was a reduction between Preparatory Period II and Competitive Period II (p = 0.006), in the Pre-QBE, there was a reduction between Preparatory Period II and Competitive Period III (p = 0.002), and in the Post-TQR, this reduction was observed between Competitive Period I and Preparatory Period II (p = 0.03). In the Post-QBE, there was an increase between Preparatory Period I and Competitive Period I (p = 0.002), followed by a decrease in Preparatory Period II (p = 0.01). Conclusion Loads varied throughout the season, along with recovery, which varied according to the loads and characteristics of each period.

Soil sampling was conducted in six different locations, i.e., flat area with mulch, sloped area with mulch, the flat area without mulch, sloped area without mulch, flat forest area, and sloped forest area. Microarthropods were obtained from soil samples using a Berlese Funnel method. Soil quality was analyzed using QBS-ar index which was calculated based on Eco-morphological Index (EMI). The results showed that the value of QBS-ar index in potato farmland with the use of plastic mulch was much higher than in farmland without plastic mulch in bothflat and sloped area. Compared to the soil in the forest area, the value of QBS-ar index in farmland with the use of plastic mulch, especially in the flat area, was relatively similar. Hence, the use of plastic mulch for potato cultivation in the hilly area is effective in maintaining soil quality. This finding would be beneficial for developing a soil conservation strategy to achieve sustainable agriculture in Dieng agricultural area.

Abstract:

Faster project delivery and the infusion of contractor knowledge into design are the primary drivers for choosing construction manager–general contractor (CM-GC) project delivery. This study focuses on the use of qualifications-based selection (QBS) and best-value (BV) procurement approaches, how and why agencies use each approach, and their associated opportunities and obstacles. Data for this study were obtained from a majority of federally funded CM-GC projects completed between 2004 and 2015. It was found that the use of BV procurement versus QBS procurement had no statistically significant difference in project characteristics or in performance of the projects in the data set. The choice of BV or QBS procurement coincided with an agency’s CM-GC stage of organizational development and influences of nonagency stakeholders on the CM-GC process. When agencies and the local industry were new to CM-GC, they were found to use BV procurement because it is closer to the traditional procurement culture and is perceived to result in a fair market project price. Alternatively, agencies and local industry partners with an established history of using CM-GC projects were found to choose QBS procurement. Because of the low level of design at the time of procurement, assumptions relating to risk, production rates, materials sources, and other aspects may be too preliminary to secure a reliable price. The use of BV procurement was found to pose a risk to innovation and to increase negotiation efforts. Qualitative trends from the project data, interviews, and the literature point to agencies using QBS procurement for the majority of CM-GC projects and BV procurement for CM-GC projects with lesser complexity or more highly developed designs at the time of selection.

Abstract:

Research in economic history frequently uses human height as a proxy for net nutrition. This anthropometric method enables historians to measure time trends and differences in nutritional status. However, the most widely used data sources for historical heights, military mustering registers, cannot be regarded as random samples of the underlying population. The lower side of the otherwise normal distribution is eroded by a phenomenon called shortfall, because shorter individuals are under-represented below a certain threshold (truncation point). This paper reviews two widely used methods for analyzing historical height samples with shortfall -the Quantile Bend Estimator (QBE) and the Reduced Sample Maximum Likelihood Estimator (RSMLE). Because of the drawbacks of these procedures, a new computational approach for identifying the truncation point of height samples with shortfall, using density estimation techniques, is proposed and illustrated on an Austrian dataset. Finally, this procedure, combined with a truncated regression model, is compared to the QBE to estimate the mean and the standard deviation. The results demonstrate the deficiencies of the QBE again and cast a good light on the new method.

Abstract:

Un accesso vascolare (AV) ben funzionante è la premessa necessaria per il buon esito di un trattamento dialitico. Il ruolo dell'infermiere nella sorveglianza e nel monitoraggio dell'AV è di fondamentale importanza sia nell'educazione del paziente sia nella prevenzione e nella precoce segnalazione delle complicanze. Nel nostro Centro abbiamo iniziato un protocollo mensile di misurazione della portata dell'AV attraverso l'utilizzo della metodica a diluizione a ultrasuoni, che tuttavia ha mostrato varie criticità per l'elevato numero di fistole arterovenose, la presenza di un unico strumento per più Centri, e la mal tolleranza dei pazienti per il cambio spesso necessario della posizione degli aghi e l'allungamento del tempo della seduta dialitica. Abbiamo quindi pensato di mettere a punto un test di pre-screening semplice e rapido, il QB stress test (QBST), che ci permettesse di selezionare solo quella popolazione a rischio da sottoporre a ulteriori accertamenti diagnostici. Dopo 5 anni di follow-up attraverso QBST ed esame clinico possiamo dire che il test è facile e veloce da eseguire ed è ben tollerato dai pazienti, ai quali non viene cambiata la posizione degli aghi né allungata la seduta dialitica. Inoltre nei pazienti negativi al test non abbiamo avuto nessun episodio trombotico.

Abstract:

In this work Amplified Brain Storm Optimization (ABS) algorithm and Quantum based Brain Storm (QBS) Optimization Algorithm is used for solving optimal reactive power problem. In the projected amplified Brain storm optimization algorithm Hamiltonian cycle has been applied to improve the search abilities and also to avoid of trap in local optimal solution. A node is arbitrarily chosen from the graph as the preliminary point to form a Hamiltonian cycle. At generation t and t+1, Lt and Lt+1 are the length of Hamiltonian cycle correspondingly. In the QBS algorithm a Quantum state of an idea is illustrated by a wave function as an alternative of the position modernized only in Brain storm optimization algorithm. Monte Carlo simulation method is used, to measure the position for each idea from the quantum state to the traditional one. Proposed Amplified Brain Storm Optimization (ABS) algorithm and Quantum based Brain Storm (QBS) Optimization Algorithm has been tested in standard IEEE 57 bus test system and simulation results show the projected algorithms reduced the real power loss effectively.

Abstract:

Previous studies have revealed the relationship between the Madden–Julian oscillation (MJO) and the Arctic Oscillation (AO). The MJO phase 2/3 is followed by the positive AO phase, and the MJO phase 6/7 is followed by the negative AO phase. This study reveals that the MJO phase 6/7–AO connection is modulated by the Quasi-Biennial Oscillation (QBO) through both tropospheric and stratospheric pathways during boreal winter. The MJO 2/3 phase and AO relationship is favored in both QBO easterly (QBOE) and westerly (QBOW) years because of the MJO-triggered tropospheric Rossby wave train from the tropics toward the polar region. The AO following the MJO 6/7 phase shifts to negative in QBOW years, but the MJO–AO connection diminishes in QBOE years. In QBOW years, the Asian-Pacific jet is enhanced, leading to more evident poleward propagation of tropospheric Rossby wave train, which contributes to the tropospheric pathway of the AO–MJO 6/7 connection. Besides, the enhanced Asian-Pacific jet in QBOW years is favorable for vertical propagation of planetary waves into the stratosphere in MJO phase 6/7, leading to negative AO, which indicates the stratospheric pathway of the AO–MJO 6/7 connection.

Abstract:

Lambdoid bacteriophage Q protein mediates the switch from middle to late bacteriophage gene expression by enabling RNA polymerase (RNAP) to read through transcription terminators preceding bacteriophage late genes. Q loads onto RNAP engaged in promoter-proximal pausing at a Q binding element (QBE) and adjacent sigma-dependent pause element (SDPE) to yield a Q-loading complex, and Q subsequently translocates with RNAP as a pausing-deficient, termination-deficient Q-loaded complex. Here, we report high-resolution structures of 4 states on the pathway of antitermination by Q from bacteriophage 21 (Q21): Q21, the Q21-QBE complex, the Q21-loading complex, and the Q21-loaded complex. The results show that Q21 forms a torus, a “nozzle,” that narrows and extends the RNAP RNA-exit channel, extruding topologically linked single-stranded RNA and preventing the formation of pause and terminator hairpins.

Abstract:

The work is devoted to the reliability of non-recoverable two-channel automation systems and computer equipment. As alternative options, a system with block duplication (SBD) and a system with a quasi-bridge structure (QBS) are considered. SBD in general is a two-channel system consisting of a series connection of duplicated nodes of different reliability. In case of failure of one of the functional subunits (FSU) of the duplicated node using the control and reconfiguration (SCR) scheme, it is masked, withdrawn from the computational process, and reconfigured the system structure in the “Non Stop” operating mode. A QBS system also represents a two-channel structure, but consisting of a serial connection of duplicated nodes of equal reliability, while the technical element intensity (redundancy level) and the functionality of this system are identical to SPD. The QBS system is also a fail-safe system that provides the “Non Stop” mode of operation. The probabilistic-physical calculation method (WF-method) is used as a tool for studying the reliability of systems, which is based on the diffusion distribution of mean-time-to-failure (DN-distribution), specially formalized for assessing the reliability of electronic, electrical and electromechanical elements and systems. While maintaining the redundancy level of the considered two-channel redundant systems, decomposing the channels into equally reliable duplicated nodes leads to the R-effect – an increase in the likelihood of system uptime with an increase in the number of nodes. The presence of the R-effect was established by other methods of calculation and by statistical modeling for both non-restored and restored systems.

Abstract:

Abstract This study investigates the interaction of the quasi-biennial oscillation (QBO) and the El Niño–Southern Oscillation (ENSO) in the troposphere separately for the North Pacific and North Atlantic region. Three 145-yr model simulations with NCAR’s Community Earth System Model Whole Atmosphere Community Climate Model (CESM-WACCM) are analyzed where only natural (no anthropogenic) forcings are considered. These long simulations allow the authors to obtain statistically reliable results from an exceptional large number of cases for each combination of the QBO (westerly and easterly) and ENSO phases (El Niño and La Niña). Two different analysis methods were applied to investigate where nonlinearity might play a role in QBO–ENSO interactions. The analyses reveal that the stratospheric equatorial QBO anomalies extend down to the troposphere over the North Pacific during Northern Hemisphere winter only during La Niña and not during El Niño events. The Aleutian low is deepened during QBO westerly (QBOW) as compared to QBO easterly (QBOE) conditions, and the North Pacific subtropical jet is shifted northward during La Niña. In the North Atlantic, the interaction of QBOW with La Niña conditions (QBOE with El Niño) results in a positive (negative) North Atlantic Oscillation (NAO) pattern. For both regions, nonlinear interactions between the QBO and ENSO might play a role. The results provide the potential to enhance the skill of tropospheric seasonal predictions in the North Atlantic and North Pacific region.

Abstract:

The large amount of information stored in audio and video repositories makes search on speech (SoS) a challenging area that is continuously receiving much interest. Within SoS, spoken term detection (STD) aims to retrieve speech data given a text-based representation of a search query (which can include one or more words). On the other hand, query-by-example spoken term detection (QbE STD) aims to retrieve speech data given an acoustic representation of a search query. This is the first paper that presents an internationally open multi-domain evaluation for SoS in Spanish that includes both STD and QbE STD tasks. The evaluation was carefully designed so that several post-evaluation analyses of the main results could be carried out. The evaluation tasks aim to retrieve the speech files that contain the queries, providing their start and end times and a score that reflects how likely the detection within the given time intervals and speech file is. Three different speech databases in Spanish that comprise different domains were employed in the evaluation: the MAVIR database, which comprises a set of talks from workshops; the RTVE database, which includes broadcast news programs; and the SPARL20 database, which contains Spanish parliament sessions. We present the evaluation itself, the three databases, the evaluation metric, the systems submitted to the evaluation, the evaluation results and some detailed post-evaluation analyses based on specific query properties (in-vocabulary/out-of-vocabulary queries, single-word/multi-word queries and native/foreign queries). The most novel features of the submitted systems are a data augmentation technique for the STD task and an end-to-end system for the QbE STD task. The obtained results suggest that there is clearly room for improvement in the SoS task and that performance is highly sensitive to changes in the data domain.

Abstract:

Design Services have not met the value and expectations of the clients and their project managers. A previous research project studied the impact of the price based award environment on construction practices, and this research proposes that designers’ current practices and expectations are also price based and not performance based asperceived by many due to the qualifications based system [QBS] approach. The authors also propose that the qualification-based system [QBS] is a price based system and should be replaced by a best value approach, which includes a best value selection process such as the Performance Information Procurement System (PIPS.) The proposed design model will give control and risk management capability back to designers by having the designers utilize expertise, create transparency utilizing a weekly risk report (WRR) and a risk management plan (RMP.) The new model utilizes the expert’s expertise to create transparency, giving the advantage to the higher performing professionals. The researchers interviewed over 400 professionals to validate the concepts of the best value approach for the design community.

Abstract:

AbstractThe usefulness of 2 methods for biomonitoring of the effects of land rehabilitation were compared in Pszów (Upper Silesian Coal Basin, south of Poland). Thirty-one species of mesostigmatid mites were collected from 3 study plots representing different stages of restoration of the mine dump Wrzosy in Pszów and community structure of the mites was analysed. There was a general trend for mesostigmatid species richness, diversity, and density to increase with the development of vegetation. The dominant early successional mesostigmatid species was the phoreticHypoapis claviger. During this study, 4616 specimens of soil microarthropods were extracted in total. They were classified according to the Biological Soil Quality Index (QBS). We tested the sensitivity and usefulness of this index for monitoring of soil quality and found its good relationship with successional stages in the reclaimed mine dump. Thus the QBS index seems to be an efficient index for monitoring the effects of restoration in mine dumps. It is a simpler, quicker, and cheaper bioindicator method than the earlier method based on community structure analysis of mesostigmatid mites.
