Tissue Biocompatibility and Antimicrobial Properties of Sympathomimetic Nasal Solutions for Potential Use in Dental Pulpal Management - Data Sharing Archive
No full textFigure DataThe aim of this study was to assess these sympathomimetic nasal solution’s biocompatibility with human dental pulp stem cells (hDPSCs) and ability to kill a deep caries-associated pathogen, Rothia dentocariosa. NS-PHE and NS-OXY (both original and kids) had antimicrobial activity toward R. dentocariosa and comparable biocompatibility with hDPSCs. The data has been published in an article titled "Tissue Biocompatibility and Antimicrobial Properties of Sympathomimetic Nasal Solutions for Potential Use in Dental Pulpal Management." The data in this record supports the figures in the published manuscript.This study was funded by NIH grant R01 DE027669.Jones, Robert S; Garcia, Roman; Mutreja, Isha; Kumar, Dhiraj. (2025).

Probing Primordial Features with the Stochastic Gravitational Wave Background
No full textThe stochastic gravitational wave background (SGWB) offers a new opportunity to observe signals of primordial features from inflationary models. We study their detectability with future space-based gravitational waves experiments, focusing our analysis on the frequency range of the LISA mission. We compute gravitational wave spectra from primordial features by exploring the parameter space of a two-field inflation model capable of generating different classes of features. Fine-tuning in scales and amplitudes is necessary for these signals to fall in the observational windows. Once they show up, several classes of frequency-dependent oscillatory signals, characteristic of different underlying inflationary physics, may be distinguished and the SGWB provides a window on dynamics of the primordial universe independent of cosmic microwave background and large-scale structure. To connect with future experimental data, we discuss two approaches of how the results may be applied to data analyses. First, we discuss the possibility of reconstructing the signal with LISA, which requires a high signal-to-noise ratio. The second more sensitive approach is to apply templates representing the spectra as estimators. For the latter purpose, we derive templates that can accurately capture the spectral features of several classes of feature signals and compare them with the SGWB produced by other physical mechanisms
Generating primordial features at large scales in two field models of inflation
No full textWe investigate the generation of features at large scales in the primordial power
spectrum (PPS) when inflation is driven by two scalar fields. In canonical single field models
of inflation, these features are often generated due to deviations from the slow-roll regime.
While deviations from slow-roll can be naturally achieved in two field models due to a sharp
turn in the trajectory in the field space, features at the largest scales of the types suggested by
CMB temperature anisotropies are more difficult to achieve in models involving two canonical
scalar fields due to the presence of isocurvature fluctuations. We show instead that a coupling
between the kinetic terms of the scalar fields can easily produce such features. We discuss
models whose theoretical predictions are consistent with current observations and highlight
the implications of our results
Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
A Unified Shell model for Buoyancy-Driven Turbulence
No full textWe construct a unified shell model for stably stratified and convective turbulence. Shell model simulation of stably stratified flow in turbulent regime exhibit Bolgiano-Obukhbov (BO) scaling in which the kinetic energy spectrum varies as . However, simulation of convective turbulence shows Kolmogorov's spectrum. These results are consistent with the direct numerical simulations of Kumar {\em et al.} [Phys. Rev. E {\bf 90}, 023016 (2014)]. We also observe a dual scaling ( and ) for a limited range of parameters in stably stratified flow

Fluoride and Gallein Inhibit Polyphosphate Accumulation by Oral Pathogen Rothia dentocariosa - Data Sharing Archive
No full textProtocol Description, Raw Data Results, and Figure Data from collaboration between Earth and Environmental Science and the School of Dentistry.This raw data set supports publication found in Letters in Applied Microbiology:
The uptake and storage of extracellular orthophosphate (Pi) by polyphosphate (polyP) accumulating bacteria may contribute to mineral dissolution in the oral cavity. To test the effect of potential inhibitors of polyP kinases on Rothia dentocariosa, gallein (0, 25, 50, 100 µM) and fluoride (0, 50, 100 ppm) were added to R. dentocariosa cultures grown in brain heart infusion broth. At late log growth phase (8h), extracellular Pi was measured using an ascorbic acid assay, and polyP was isolated from bacterial cells treated with RNA/DNAases using a neutral phenol/chloroform extraction. Extracts were hydrolyzed and quantified as above. Gallein and fluoride had minor effects on bacterial growth with NaF having a direct effect on media pH. Gallein (≥25 µM) and fluoride (≥50 ppm) attenuated the bacterial drawdown of extracellular Pi 56.7% (p <0.05) and 37.3% (p <0.01). There was a corresponding polyP synthesis decrease of 73.2% (p<0.0001) from gallein and 83.1% (p<0.0001) from fluoride. Attenuated total reflectance Fourier transform infrared spectroscopy validated the presence of polyP and its reduced concentration in R. dentocariosa bacterial cells following gallein and fluoride treatment. R. dentocariosa can directly change extracellular Pi and accumulate intracellular polyP but the mechanism is attenuated by gallein and NaF.NIH/NIDCR R01DE027669Kumar, Dhiraj; Mandal, Subhrangshu; Bailey, Jake V.; Flood, Beverly E.; Jones, Robert S.
