Tomographic performance characteristics of the IQ&#x25CF;SPECT system (2011)

The IQ·SPECT system was introduced by Siemens in 2010 to significantly improve the efficiency of myocardial perfusion imaging (MPI) using conventional, large field-of-view (FOV) SPECT and SPECT·CT systems. With IQ·SPECT, it is possible to perform MPI scans in one-fourth the time or using one-fourth the administered dose as compared to a standard protocol using parallel-hole collimators. This improvement is achieved by means of a proprietary multifocal collimator that rotates around the patient in a cardio-centric orbit resulting in a four-fold magnification of the heart while keeping the entire torso in the FOV. The data are reconstructed using an advanced reconstruction algorithm that incorporates measured values for gantry deflections, collimator-hole angles, and system point response function. This article explores the boundary conditions of IQ·SPECT imaging, as measured using the Data Spectrum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> cardiac torso phantom with the cardiac insert. Impact on reconstructed image quality was evaluated for variations in positioning of the myocardium relative to the sweet spot, scan-arc limitations, and for low-dose imaging protocols. Reconstructed image quality was assessed visually using the INVIA 4DMSPECT and quantitatively using Siemens internal IQ assessment software. The results indicated that the IQ·SPECT system is capable of tolerating possible mispositioning of the myocardium relative to the sweet spot by the operator, and that no artifacts are introduced by the limited angle coverage. We also found from the study of multiple low dose protocols that the dwell time will need to be adjusted in order to acquire data with sufficient signal-to-noise ratio for good reconstructed image quality.
Uncertainty quantification in dimensions dataset of additive manufactured NIST standard test artifact (2021)

The printed features on an additive manufactured part will often deviate from the nominal values of the 3D model's features due to the factors such as printer resolution, printing parameters, printing technology, and the measurement method. The National Institute of Standards and Technology (NIST) standard test artifact contains a collection of various features that can be used to characterize a 3D printer's performance and has been used to benchmark metal printers. There is limited documentation on how well different additive manufacturing processes can fabricate the NIST artifact. This dataset records the dimensional uncertainty of selective printed features of the NIST artifact manufactured with polymer and resin printing processes. It contains the post-processing dimensional measurements of geometric features on the printed test artifacts. In order to generate the data, a total of 16 samples of the test artifact were printed with fused deposition modelling (FDM) and stereolithography (SLA) additive manufacturing methods. The percentage error between the measurement of features in the printed samples and their nominal computer aided design (CAD) values are calculated. For future reusability of this data, the same NIST test artifact CAD model can be printed, and the features’ measurements can be compared with the dataset presented in this article.

The Development of a New Multi-AV System Incorporating an On-Board Navigation Function (1993)

&lt;div class="htmlview paragraph"&gt;A new multi-AV system was developed for use in the 1991 Cedric,Gloria and Cima models. This system features the world's first production vehicle application of an optical fiber gyro, which dramatically improves position finding accuracy. New map-matching logic was also created and the map database was expanded so that the map-matching function can be used throughout Japan. Another first-ever feature in production vehicles is the compatibility with roadside beacons of the Vehicle Information and Communications System ( VICS ),enabling reception of Intersection information and automatic correction of vehicle position based on the data received. A touch screen has been adopted for greater ease of operation,with screen switches newly provided for air-conditioner controls and a cellular car phone. This paper describes the configuration, functions and performance of the new multi-AV system.&lt;/div&gt;
Characterization of Thin Anodized Films on Aluminum with Soft X‐ray Spectroscopy (1976)

Two methods utilizing x‐ray spectra from the electron microbeam probe for the determination of aluminum oxide film thickness for a broad range of thicknesses are described. One method uses the direct measurement of oxygen K emission while the other uses the changes in fine features of the x‐ray spectra with changes in oxide film thickness. For oxides formed by barrier anodization technique, films as thin as 20–30Å and as thick as several thousand angstroms could be measured by these methods.
Dose‐dependent effects of endotoxins on allergen sensitization and challenge in the mouse (2004)

Our data clearly demonstrate that exposure to LPS influences allergen-induced IgE production and airway eosinophilia in a time and dose-dependent manner, preventing IgE production and development of eosinophilia when administered during allergen sensitization at high doses, and inducing exacerbation of eosinophilia when administered upon allergen challenge at low doses, including infra-clinical doses.
INTRAORAL CORROSION RESULTING FROM COUPLING DENTAL IMPLANTS AND RESTORATIVE METALLIC SYSTEMS (1992)

Materials used for the construction of dental restorations and implants include a wide range of metals and alloys, ceramics and carbons, and polymers. When metals and alloys are placed in direct contact in the oral cavity, a galvanic cell can be formed that may compromise the longevity of one or more of the materials in the couple. In vitro electrochemical corrosion analyses have proven to be a valuable tool for providing guidance on the selection of metallic materials. These analyses can provide basic data on electrochemical potentials, current rates, and the evaluation of galvanic corrosion conditions. This article seeks to provide the clinician with information that can be valuable in the selection of metallic materials that may be placed in direct contact with one another in the oral cavity.
PDE estimation techniques for advanced battery management systems &#x2014; Part II: SOH identification (2012)

A critical enabling technology for electrified vehicles and renewable energy resources is battery energy storage. Advanced battery systems represent a promising technology for these applications, however their dynamics are governed by relatively complex electrochemical phenomena whose parameters degrade over time and vary across material design. Moreover, limited sensing and actuation exists to monitor and control the internal state of these systems. As such, battery management systems require advanced identification, estimation, and control algorithms. In this paper we examine state-of-health (SOH) estimation, framed as a parameter identification problem for parabolic PDEs and nonlinearly parameterized output functions. Specifically, we utilize the swapping identification method for unknown parameters in the diffusion partial differential equation (PDE). A nonlinear least squares method is applied to the output function to identify its unknown parameters. These identification algorithms are synthesized from the single particle model (SPM). In a companion paper we examine a new battery state-of-charge (SOC) estimation algorithm based upon the backstepping method for PDEs.
Comparative Antiviral Activity of Remdesivir and Anti-HIV Nucleoside Analogs against Human Coronavirus 229E (HCoV-229E) (2020)

Remdesivir is a nucleotide prodrug that is currently undergoing extensive clinical trials for the treatment of COVID-19. The prodrug is metabolized to its active triphosphate form and interferes with the action of RNA-dependent RNA polymerase of SARS-COV-2. Herein, we report the antiviral activity of remdesivir against human coronavirus 229E (HCoV-229E) compared to known anti-HIV agents. These agents included tenofovir (TFV), 4'-ethynyl-2-fluoro-2'-deoxyadenosine (EFdA), alovudine (FLT), lamivudine (3TC), and emtricitabine (FTC), known as nucleoside reverse-transcriptase inhibitors (NRTIs), and a number of 5'-<i>O</i>-fatty acylated anti-HIV nucleoside conjugates. The anti-HIV nucleosides interfere with HIV RNA-dependent DNA polymerase and/or act as chain terminators. Normal human fibroblast lung cells (MRC-5) were used to determine the cytotoxicity of the compounds. The study revealed that remdesivir exhibited an EC<sub>50</sub> value of 0.07 µM against HCoV-229E with TC<sub>50</sub> of > 2.00 µM against MRC-5 cells. Parent NRTIs were found to be inactive against (HCoV-229E) at tested concentrations. Among all the NRTIs and 5'-<i>O</i>-fatty acyl conjugates of NRTIs, 5'-<i>O</i>-tetradecanoyl ester conjugate of FTC showed modest activity with EC<sub>50</sub> and TC<sub>50</sub> values of 72.8 µM and 87.5 µM, respectively. These data can be used for the design of potential compounds against other coronaviruses.
Circadian Gene Expression in Mouse Renal Proximal Tubule (2022)

ABSTRACT Circadian variability in kidney function has long been recognized but is often ignored as a potential confounding variable in in vivo physiological experiments. To provide a guide for physiological studies on the kidney proximal tubule, we have now created a data resource consisting of expression levels for all measurable mRNA transcripts in microdissected proximal tubule segments from mice as a function of the time of day. This approach employs small-sample RNA-sequencing (RNA-seq) applied to microdissected renal proximal tubules including both S1 proximal convoluted tubules (PCTs) and S2 proximal straight tubules (PSTs). The data were analyzed using JTK-Cycle to detect periodicity. The data are provided as a user-friendly web page at https://esbl.nhlbi.nih.gov/Databases/Circadian-Prox/ . In PCTs, 234 transcripts were found to vary in a circadian manner (3.7 % of total quantified). In PSTs, 334 transcripts were found to vary in a circadian manner (5.3 % of total quantified). Transcripts previously known to be associated with corticosteroid action and transcripts associated with increased flow were found to be overrepresented among circadian transcripts peaking during the “dark” portion of the day (Zeitgeber 14-22), corresponding to the peak levels of corticosterone and glomerular filtration rate in mice. Blurb Circadian variation in gene expression can be an important determinant in the regulation of kidney function. The authors used RNA-seq in microdissected proximal S1 and S2 segments to identify transcripts that vary in a circadian manner. The data were used to construct a user-friendly web resource.
Aspirin Inhibits Serine Phosphorylation of Insulin Receptor Substrate 1 in Tumor Necrosis Factor-treated Cells through Targeting Multiple Serine Kinases (2003)

The hypoglycemic effects of high dose salicylates in the treatment of diabetes were documented before the advent of insulin. However, the molecular mechanisms by which salicylates exert these anti-diabetic effects are not well understood. In this study, we analyzed the effects of aspirin (acetylsalicylic acid) on serine phosphorylation of insulin receptor substrate 1 (IRS-1) in cells treated with tumor necrosis factor (TNF)-alpha. Phosphorylation of IRS-1 at Ser307, Ser267, and Ser612 was monitored by immunoblotting with phospho-specific IRS-1 antibodies. In 3T3-L1 and Hep G2 cells, phosphorylation of IRS-1 at Ser307 in response to TNF-alpha treatment correlated with phosphorylation of JNK, c-Jun, and degradation of IkappaBalpha. Moreover, phosphorylation of IRS-1 at Ser307 in embryo fibroblasts derived from either JNK or IKK knockout mice was reduced when compared with that in the wild-type controls. Taken together, these data suggest that serine phosphorylation of IRS-1 in response to TNF-alpha is mediated, in part, by JNK and IKK. Interestingly, aspirin treatment inhibited the phosphorylation of IRS-1 at Ser307 as well as the phosphorylation of JNK, c-Jun, and degradation of IkappaBalpha. Furthermore, other serine kinases including Akt, extracellular regulated kinase, mammalian target of rapamycin, and PKCzeta were also activated by TNF-alpha (as assessed by phospho-specific antibodies). Phosphorylation of IRS-1 at Ser267 and Ser612 correlated with the activation of these kinases. Phosphorylation of Akt and the mammalian target of rapamycin (but not extracellular regulated kinase or PKCzeta) in response to TNF-alpha was inhibited by aspirin treatment. Finally, aspirin rescued insulin-induced glucose uptake in 3T3-L1 adipocytes pretreated with TNF-alpha. We conclude that aspirin may enhance insulin sensitivity by protecting IRS proteins from serine phosphorylation catalyzed by multiple kinases.
Dynamically Adjusting Scale of a Kubernetes Cluster under QoS Guarantee (2019)

Nowadays, the container-based virtualization technologies have become very popular due to lightweight nature, scalability, flexibility and others. Kubernetes is one of the most popular container cluster management systems, which enables users to deploy applications on the container easily, so more and more web applications are deployed in a Kubernetes clusters. However, a Kubernetes cluster is generally designed to handle the peak of workloads, so that most of resources are idle in usual time, which results in an huge waste of resource. Hence, it is necessary to design a system to improve the cluster resource utilization and promise Quality of Service (QoS) in a Kubernetes cluster. In this paper, we propose a generic system to dynamically adjust the scale of a Kubernetes cluster, which is able to reduce the waste of resource on the premise of QoS guarantee. The proposed system contains four modules: monitor module, QoS module, scaling module, and executing module. First, the monitor module uses two open-source tools, Heapster and InfluxDB, to monitor and store real-time status of a Kubernetes cluster. Then, to guarantee QoS in the Kubernetes cluster, the QoS module presents a method to automatically decide a threshold of CPU utilization that is able to meet requirements of a specific application. Next, the scaling module provides a cluster scaling algorithm to get an ideal number of nodes in the Kubernetes cluster, which is used to allocate resources in a cluster-level allocation. Finally, according to the ideal number of nodes, the executing module adjusts the scale of the Kubernetes cluster to carry out the application. Extensive experiments in real environments show that, on average, the proposed system improves CPU utilization of a Kubernetes cluster by 28.99%.

Effects of partial rotor demagnetization on permanent magnet synchronous machines (2010)

The effects of magnet faults on the rotor of permanent magnet synchronous machines are analyzed in the present work. In particular, demagnetization effects are analyzed using the finite element method. Two different stator winding configurations are considered in the analysis, series and parallel connected windings. From this analysis, a fault detection strategy based on the information contained in winding-current spectrum is proposed. A fault severity factor is also proposed to quantify residual magnetism losses (demagnetization) on a single magnet. This factor is practically independent from the motor load conditions. Experimental results are presented to validate the proposal.
The Effect of a Target Bite Count and Plate Size on Food Intake. (2015)

The purpose of this study was to determine if an instruction to take fewer bites than typically taken, would reduce intake and overcome the known environmental cue of plate size. In a previous study, fifty-five participants (34F) ate ad libitum macaroni and cheese in groups of four, either from a small plate or a large plate. They ate 111Â±35g with 12Â±4 bites from the small plate, and 195Â±111g with 20Â± 6 bites from the large plate. The current study employed the same paradigm. Sixty participants (33F) were given bite count feedback and were instructed to take only 12 bites, while eating from either a small plate or a large plate. Participants ate 135Â±52g with 12Â±3 bites from the small plate and 177Â±63g with 12Â±2 bites from the large plate. Results of a 2x2 ANOVA indicate a main effect of plate size (p&lt;.001) and instruction (p&lt;.001) on bites taken and an interaction (p&lt;.001). Plate size also affected grams consumed (p&lt;.001). Notably, instruction also affected bite size (p&lt;.001). These results suggest that people will reduce the number of bites when instructed to, but will increase their bite size to compensate for the reduced bite allowance.
Affinage de l'emmental : dynamique des populations bactériennes et évolution de la composition de la phase aqueuse (1998)

Swiss cheese ripening: dynamics of bacterial populations and evolution of the aqueous phase composition for three industrial cheeses. To understand and control cheese ripening, it is essential to know the kinetics of the microbial and biochemical changes occurring during ripening. For three Swiss cheeses industrially manufactured, differing particularly in ripening times and temperatures, we determined throughout the ripening the dynamics of starter and non-starter flora and the changes in the composition of cheese aqueous phase extracted by pressing. Three flora succeeded one another during ripening: thermophilic lactic starters, non-starter lactic acid bacteria and propionibacteria. The viability of lactic starters fell during ripening from 10 9 to 10 8 -10 5 cfu-g " more or less rapidly, depending on the cheeses. Propionibacteria reached lOSto 410 8 cfu-g'" at the end of ripening. Non-starter lactic acid bacteria grew from the beginning of ripening and reached populations as high as 10 8 to 5 10 8 cfu-g:". They were composed of heterofermentative lactobacilli, Lactobacillus paracasei constituting the predominant species (56% to 88% of the isolates). The aqueous phase composition showed similar changes for the three cheeses. Nitrogen matter increased from 13-18 to 54-68 g-kg" during ripening, with a rate depending on the ripening room temperature. Free amino acids increased from 10-29% to 45-47% of the nitrogen matter of the aqueous phase, but their relative proportion remained essentially constant, apart from amino acids catabolised by bacteria (Arg and Asp in particular). Most minerai exchanges between curd and aqueous phase occurred before the ripening during the curd acidification, resulting in high levels of Ca, Mg and P in aqueous phase (respectively about 6.5, 0.65 and 1.2 g-kg "), Mineral composition showed only minor changes during ripening. Citrate (1.7-2.4 gkg-I in aqueous phase at the beginning ofripening) was consumed during co Id room ripening, presumably by non-starter flora. Lactate (34-36 gkg-I ) decreased only by 1 to 2 gkg-1 in the three cheeses. InralElsevier, Paris.
The Role of Labral Lesions to Development of Early Degenerative Hip Disease (2001)

The current authors examined the hypothesis that labral lesions contribute to early degenerative hip disease. Between 1993 and 1999, 436 consecutive hip arthroscopies were done by the senior author. In addition, 54 acetabula were harvested from human adult cadavers. Two hundred forty-one of the 436 (55.3%) patients who had arthroscopies had a 261 labral tears, all located at the articular, not capsular margin of the labrum. Stereomicroscopic examination of the 54 acetabula from cadavers revealed 52 labral lesions. Overall, there was no significant difference between the arthroscopic and cadaveric populations in terms of the incidence of labral tears. (Overall, 73% of patients with fraying or a tear of the labrum had chondral change. Arthroscopic and anatomic observations support the concept that labral disruption and degenerative joint disease are frequently part of a continuum of joint disease.
Capacity Scaling of Cellular Networks: Impact of Bandwidth, Infrastructure Density and Number of Antennas (2017)

The availability of very wide spectrum in millimeter wave bands combined with large antenna arrays and ultra dense networks raises two basic questions: What is the true value of overly abundant degrees of freedom and how can networks be designed to fully exploit them? This paper determines the capacity scaling of large cellular networks as a function of bandwidth, area, number of antennas and base station density. It is found that the network capacity has a fundamental bandwidth scaling limit, beyond which the network becomes power-limited. An infrastructure multi-hop protocol achieves the optimal network capacity scaling for all network parameters. In contrast, current protocols that use only single-hop direct transmissions can not achieve the capacity scaling in wideband regimes except in the special case when the density of base stations is taken to impractical extremes. This finding suggests that multi-hop communication will be important to fully realize the potential of next-generation cellular networks. Dedicated relays, if sufficiently dense, can also perform this task, relieving user nodes from the battery drain of cooperation. On the other hand, more sophisticated strategies such as hierarchical cooperation, that are essential for achieving capacity scaling in ad hoc networks, are unnecessary in the cellular context.
