A New Tubing Change Procedure for CAPD Patients (1983)

Thirty continuous ambulatory peritoneal dialysis (CAPD) patients at the Acorn Research Laboratory participated in a four month study, which examined the safety and emcacy of a new tubing change procedure. This study indicates that CAPD personnel safely can alter the traditional tubing change procedure while lessening the time required to change transfer sets. The study also indicates that the new tubing change procedure may decrease the frequency of peritonitis associated with tubing changes.
Extending a Prolog architecture for high performance numeric computations (2003)

The Aquarius numeric processor (ANP) is an extended numeric instruction set architecture that is based on the Berkeley programmed logic machine (PLM) and supports integrated symbolic and numeric calculations. This extension expands the existing numeric data type to include 32- and 64-bit integers and single- and double-precision floating-point numbers conforming to the IEEE Standard P754. A class of data structure called numeric arrays has been added to represent matrices and arrays found in most scientific programming languages. Powerful numeric instructions are included to manipulate these novel data types. The authors describe the programming model and the architecture of the ANP. An experimental ANP is currently under construction using TTL (transistor-transistor logic) and ECL (emitter-coupled logic) parts. Simulated performance results indicate that the system will achieve about 10 MFLOPs (millions of floating-point operations) on the Prolog version of some Whetstone and Linpack benchmarks and close to 20 MFLOPS on some matrix operations (all in double precision).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Sequence complexity of circular Epstein-Bar virus DNA in transformed cells (1981)

A simplified procedure, based on several methods previously used to isolate circular DNA molecules from bacteria, was derived for the preparation of covalently closed circular viral DNA molecules from large quantities of lymphocytes transformed by Epstein-Barr virus. The protocol can be applied both to virus nonproducer lines and to lines containing cells activated to virus production. Sufficient amounts o highly purified viral DNA of intracellular origin were obtained from B95-8 and Raji cells to allow direct visual analysis of their sequence complexities after cleavage with EcoRI and separation of fragments by gel electrophoresis. No major differences in complexity were observed between circular DNA and linear virion DNA from B95-8 cells. The fragment patterns observed in this fashion agree well with those detected by conventional blotting and hybridization methods. The procedure can also be used as an analytical method to assay for small amounts of circular Epstein-Barr virus DNA molecules in other transformed cells. In this connection, no circular Epstein-Barr virus DNA was detected in Namalva cells.
Use of Continuous Dexmedetomidine at Home for Nearly Three Years in a Young Woman with End-Stage Cyanotic Congenital Heart Disease and Cyclic Vomiting (2019)

A 14-year-old girl with a history of complex congenital heart disease in end-stage heart failure and with cyclic vomiting was admitted to our hospice program in 2012. Before hospice enrollment, she had required intermittent infusions of dexmedetomidine to abort cyclic vomiting episodes after cardiac catheterization procedures. Following a hospital admission in November 2013, she was discharged home in the care of our hospice on a continuous dexmedetomidine infusion. She remained on this infusion at varying doses (range of 0.1-0.38 mcg/kg/hour) for nearly three years, until her death in September 2016. This report describes the palliative use of dexmedetomidine in this patient and difficulties related to the use of this medication during the course of her care.

A performance-conserving approach for reducing peak power consumption in server systems (2005)

The combination of increasing component power consumption, a desire for denser systems, and the required performance growth in the face of technology-scaling issues are posing enormous challenges for powering and cooling of server systems. The challenges are directly linked to the peak power consumption of servers.Our solution, Power Shifting, reduces the peak power consumption of servers minimizing the impact on performance. We reduce peak power consumption by using workload-guided dynamic allocation of power among components incorporating real-time performance feedback, activity-related power estimation techniques, and performance-sensitive activity-regulation mechanisms to enforce power budgets.We apply our techniques to a computer system with a single processor and memory. Power shifting adds a system power manager with a dynamic, global view of the system's power consumption to continuously re-budget the available power amongst the two components. Our contributions include:• Demonstration of the greater effectiveness of dynamic power allocation over static budgeting,• Evaluation of different power shifting policies,• Analysis of system and workload factors critical to successful power shifting, and• Proposal of performance-sensitive power budget enforcement mechanisms that ensure system reliability.
Enhancement-procedure outcomes in patients implanted with the Precisight multicomponent intraocular lens (2019)

Purpose: Eyes that have undergone phacoemulsification with implantation of a multicomponent intraocular lens (MCIOL) may further undergo an enhancement procedure for correction of residual refractive errors. The enhancement procedure is accomplished by exchanging the front lens used in the primary surgery with another lens containing the correct dioptric power. We evaluated the efficacy and safety of enhancement procedures among eyes that received an MCIOL. Methods: A total of 25 eyes that had undergone phacoemulsification with implantation of an MCIOL were found to have a residual error of refraction (spherical equivalent ≥0.75 D) 3 months after primary cataract surgery, and underwent further enhancement surgery. The main study outcomes were uncorrected and corrected distance visual acuity, subjective refraction, anterior-chamber depth, pachymetry, and endothelial cell count. Results: There was a statistically significant improvement in uncorrected distance visual acuity of approximately two lines after enhancement surgery (0.20±0.20–0.02±0.08 logMAR, P <0.001) and a significant decrease in residual spherical equivalent from 1.3±1.1 D to 0±0.38 D ( P <0.001). There were no statistically significant changes in pre- and postenhancement corrected distance visual acuity, anterior-chamber depth, pachymetry, or keratometry. There was a statistically significant decrease (2.6%) in endothelial cell count ( P <0.01), which could have been endothelial equilibration from the primary procedure. All enhancement surgeries were uneventful, and no major complications were observed. Conclusion: The MCIOL-enhancement procedure demonstrates statistical and clinical improvement in uncorrected distance visual acuity and correction of postoperative refractive errors. The Precisight IOL may be a useful choice for patients with high risk of having significant residual refractive errors after primary cataract surgery. Keywords: residual refractive error, cataract, piggyback lens, multicomponent intraocular lens, intraocular lens exchange, pseudophakic emmetropia
Heparanase 2 (Hpa2)- a new player essential for pancreatic acinar cell differentiation (2023)

Heparanase 2 (Hpa2, HPSE2) is a close homolog of heparanase. Hpa2, however, lacks intrinsic heparan sulfate (HS)-degrading activity, the hallmark of heparanase enzymatic activity. Mutations of HPSE2 were identified in patients diagnosed with urofacial syndrome (UFS), a rare genetic disorder that exhibits abnormal facial expression and bladder voiding dysfunction, leading to renal damage and eventually renal failure. In order to reveal the role of HPSE2 in tissue homeostasis, we established a conditional Hpa2-KO mouse. Interestingly, the lack of Hpa2 was associated with a marked decrease in the expression of key pancreatic transcription factors such as PTF1, GATA6, and Mist1. This was associated with a two-fold decrease in pancreas weight, increased pancreatic inflammation, and profound morphological alterations of the pancreas. These include massive accumulation of fat cells, possibly a result of acinar-to-adipocyte transdifferentiation (AAT), as well as acinar-to-ductal metaplasia (ADM), both considered to be pro-tumorigenic. Furthermore, exposing Hpa2-KO but not wild-type mice to a carcinogen (AOM) and pancreatic inflammation (cerulein) resulted in the formation of pancreatic intraepithelial neoplasia (PanIN), lesions that are considered to be precursors of invasive ductal adenocarcinoma of the pancreas (PDAC). These results strongly support the notion that Hpa2 functions as a tumor suppressor. Moreover, Hpa2 is shown here for the first time to play a critical role in the exocrine aspect of the pancreas.
Boosting Water Splitting Performance of BiVO4 Photoanode through Selective Surface Decoration of Ag2S (2018)

Abstract The unsatisfactory of solar absorption and charge separation is the main loss limiting the conversion efficiency in photoelectrochemical water splitting system. Here, Ag 2 S/BiVO 4 heterostructure have been fabricated for the first time to PEC splitting water, achieving efficient solar‐to‐chemical energy conversion. The Ag 2 S nanoparticles evenly distributing on the surface of BiVO 4 not only promotes the charge separation, but also greatly facilitates the surface hole injection. The results show that the optimal Ag 2 S/BiVO 4 heterostructure reach a remarkable photocurrent density of 1.91 mA/cm 2 at 1.23 V (vs RHE) under 100 mW/cm 2 irradiation, which is approximately 3.2‐fold higher than that of bare BiVO 4 . The incident photon‐to‐current efficiency (IPCE) of Ag 2 S/BiVO 4 heterostructure have been enhanced up to 23 % in visible region ( V bias =1.23 V, 460 nm). In addition, Ag 2 S/BiVO 4 shows the attracting stability during photoelectrochemical process, since its photocurrent density can keep for 92 % after 2 h. The charges transfer mechanism for Ag 2 S/BiVO 4 heterostructure were also proposed. This work provides a new insight for constructing efficient and stable photoanodes based on BiVO 4 .
Diuretics I: 8‐Sulfamoyltheophylline and 7‐substituted derivatives (1964)

Abstract 8‐Sulfamoyltheophylline (V) was prepared by oxidative chlorination of 7‐benzyl‐8‐mercaptotheophylline, followed by amidation and debenzylation. This compound, built up from two diuretic principles, appeared to have no diuretic properties. On the other hand the intermediate 7‐benzyl‐8‐sulfamoyl‐theophylline exhibited an appreciable diuretic activity, while lacking the other pharmacological properties of theophylline. In addition this compound inhibited carbonic anhydrase. On the basis of these findings the synthesis was undertaken of a number of other 7‐substituted 8‐sulfamoyltheophyllines. The present report deals with the preparation of these heterocyclic sulfonamides, derived from V by the introduction of alkyl, aralkyl and aryl groups at the 7‐position.

Photochemistry of aromatic compounds. Part 1.—Acid-base properties of singlet and triplet excited states of pyrene derivatives and aza-aromatic compounds (1969)

Variations of acidity constants between the ground state G and the fluorescent state S1 of 1-, 2-, 4- and 9-azaphenanthrenes, 1-aminopyrene, 1-hydroxypyrene and pyrene-1-carboxylic acid have been measured by application of the Förster cycle. Triplet state pK values of the same derivatives were obtained by the flash photolysis technique. For 1-hydroxypyrene under flash photolysis conditions, only one transient, whose spectrum is not pH dependent could be observed. This transient spectrum has been assigned to the pyrenoxyl radical. There appears to be no relationship between the position of protonation of the various aza-phenanthrenes and the ΔpK between the ground state and the singlet or triplet excited states.
Response of corn yields in a Planosol soil to surface drainage, cropping system and variable fertilizer treatments (1961)

The Edina soil series of southeastern Iowa and northern Missouri are areas of relatively flat topography and poor internal drainage. For these areas, where the topography and soils permit, surface drainage is the most practical method of removing excess water from the land. One method of surface drainage that has been used on the Edina soils is bedding, in which the field is divided into narrow-width plow lands with the deadfurrows running parallel to the prevailing land slope.\nLittle is known about the relative returns from investment in a bedding system in comparison with other surface or subsurface drainage methods. Bedding requires that some topsoil be moved to obtain the desired grade for drainage. The effect on crop yields of topsoil removal and movement in land-forming operations such as bedding, however, is not quantitatively understood. It is the general purpose of this bulletin to present and analyze 6 years of corn-yield data involving drainage (bedded versus level), cropping and fertilizer variables from a study on the Southern Iowa Experimental Farm near Bloomfield.
Automatic detection of replay segments in broadcast sports programs by detection of logos in scene transitions (2002)

In broadcast sports, replays provide viewers another look at interesting events. We propose an automatic algorithm for replay segment detection by detecting frames containing logos in the special scene transitions that sandwich replays. Detected replays are utilized in efficient navigation, indexing, and summarization of sports programs. The proposed algorithm first automatically determines the logo template from frames surrounding slow motion segments, where slow motion segments are automatically detected using [4]. Then, it locates all the similar frames in the video using the logo template. Finally the algorithm identifies the replay segments by grouping the detected logo frames and slow-motion segments. Our algorithm accurately detects replays, with or without slow motion.
Impact of separator's solid‐phase ion conductivity parameter on convection battery performance and modeling (2014)

A solid‐phase ion conductivity parameter has been added to the separator of a porous electrode theory description of a convection battery performance to increase the accuracy of this model. With the addition of the ion conductivity parameter, the variances between the model and experimental data have been reduced by 80–85% in both the convection cell and the diffusion cell. The parameter is fundamentally consistent with solid‐phase mechanisms by which ions can transport through separators in parallel with liquid‐phase transport, and the improved modeling results substantiate the importance of solid or surface ion transport mechanisms at high current fluxes. Modeling was supplemented with dimensionless analysis to lump fundamental parameters that are inherently coupled in the underlying equations. From this analysis, a global parameter has been developed describing the ratio of convective charge transfer to diffusive charge transfer that characterizes the transition from diffusive to convective cell behavior. © 2014 American Institute of Chemical Engineers AIChE J , 60: 3784–3791, 2014
A coastal distributed autonomous sensor network (2011)

In-situ measurements are essential for monitoring, understanding, and predicting marine phenomena. Monitoring and sampling missions often require observations of phenomena with spatial and temporal dynamics that span different scales (e.g. seconds to months, meters to kilometers, etc). A combination of different vehicles, fixed nodes, advanced payload sensors, and advanced control algorithms are usually required for success. Basic research needs to focus on the individual elements composing such systems but also, more importantly, on strategies to ensure all components function together smoothly as a whole. The challenges presented by coastal environments, such as low depths and commercial vehicle traffic, increase the likelihood of collisions with oceanographic monitoring hardware and consequently the environmental geometry becomes an important constraint. In this study our group presents the progress and recent achievements of a distributed heterogenous autonomous sensor network that combines underwater, surface, and aerial robotic vehicles along with advanced sensor payloads, planing algorithms and learning principles to successfully operate across the scales and constraints found in coastal environments.
JAK2/STAT3 Inhibition Attenuates Noise-Induced Hearing Loss (2014)

Signal transducers and activators of transcription 3 (STAT3) is a stress responsive transcription factor that plays a key role in oxidative stress-mediated tissue injury. As reactive oxygen species (ROS) are a known source of damage to tissues of the inner ear following loud sound exposure, we examined the role of the Janus kinase 2 (JAK2)/STAT3 signaling pathway in noise induce hearing loss using the pathway specific inhibitor, JSI-124. Mice were exposed to a moderately damaging level of loud sound revealing the phosphorylation of STAT3 tyrosine 705 residues and nuclear localization in many cell types in the inner ear including the marginal cells of the stria vascularis, type II, III, and IV fibrocytes, spiral ganglion cells, and in the inner hair cells. Treatment of the mice with the JAK2/STAT3 inhibitor before noise exposure reduced levels of phosphorylated STAT3 Y705. We performed auditory brain stem response and distortion product otoacoustic emission measurements and found increased recovery of hearing sensitivity at two weeks after noise exposure with JAK2/STAT3 inhibition. Performance of cytocochleograms revealed improved outer hair cell survival in JSI-124 treated mice relative to control. Finally, JAK2/STAT3 inhibition reduced levels of ROS detected in outer hair cells at two hours post noise exposure. Together, these findings demonstrate that inhibiting the JAK2/STAT3 signaling pathway is protective against noise-induced cochlear tissue damage and loss of hearing sensitivity.

Hexamethyldisiloxane coating by plasma to create a superhydrophobic surface for fabric masks (2022)

This study evaluated the effect of hexamethyldisiloxane (HMDSO) plasma on the fabrics surface to produce masks. Samples of 400-thread count cotton fabric were used. The fabrics was covered with a layer of HMDSO employing plasma enhanced chemical vapor deposition. Optical Microscopy, helium ion beam microscopy (HIM) and atomic force microscopy (AFM) were used for topographic analysis. Fourier transformed infrared spectroscopy technique was used to analyze the chemical modifications on surface. The level of hydrophobicity was evaluated using contact angle measurements. To evaluate the effect of washing cycle on the plasma coating, a protocol proposed by the World Health Organization was used. All experiments were performed in triplicate. For the statistical analysis, the Mann–Whitney, Kruskal–Wallis and Dunn tests were used. AFM showed that, after HMDSO plasma coating, a layer of small granules agglomerated on the original surface of the fabric was visualized. The fabric, which initially had a 0° contact angle value, presented angles of 120° after the plasma coating. It was concluded that the use of cotton fabric coated with HMDSO plasma proved to be adequate for the manufacture of protective masks, since the coating made the surface hydrophobic and this property is maintained even after washing cycles.
