Numerical analyses on laminar flow and heat transfer in staggered tube banks. (1986)

Numerical analyses are presented on laminar flow and heat transfer in staggered tube banks, which are up to five rows deep, having pitch-diameter ratios of 1.5×1.5, 1.5×1.3 and 1.5×1.0, under the condition of uniform tube wall temperature in the range of Rem=120, 300 and Pr=0.7, 7.0, 300 and 800. Stream, isovorticity and isothermal lines are demonstrated. Drag coefficient and average heat transfer coefficient are compared well with existing experimental results. A new expression is proposed for predicting the average heat transfer coefficient.
The role of hypothalamic input on corticotroph maturation in fetal sheep (2003)

Corticotropin-releasing hormone receptor type 1 (CRH-R1) expression and vasopressin type 1b (V1b) receptor protein decrease in late-gestation fetal sheep. Because hypothalamo-pituitary disconnection (HPD) has been demonstrated to prevent the morphological maturation of corticotrophs, we hypothesized that hypothalamic input is necessary for the maturational changes in CRH-R1 and V1b receptor levels. We measured CRH-R1 and V1b receptor expression in the anterior pituitaries of fetuses at 140 days gestational age (dGA) that underwent HPD or sham surgery at 120 dGA. CRH-R1 mRNA decreased similarly in HPD and sham-operated fetuses compared with 120 dGA naive fetuses. However, CRH-R1 protein levels were elevated in HPD fetuses compared with sham and were not different from 120 dGA values. V1b protein levels decreased similarly in HPD and sham-operated fetuses compared with 120 dGA naive fetuses. We conclude that hypothalamic input to the pituitary is necessary for the decrease in CRH-R1 receptor protein levels in late-gestation fetal sheep. However, hypothalamic input is not necessary for the decrease in V1b receptor expression seen in late gestation.

Rainbow—a multi‐purpose CAD system (1972)

Abstract This paper describes RAINBOW, an integrated suite of programs for assisting in the specification and design of networks—electrical, logical or otherwise. Data input are primarily graphical and manual transcription of data for subsequent phases of the design analysis is virtually eliminated by the use of a uniform data base, generated at the time of input. The RAINBOW system depends heavily on the software support of a filing system with on‐line access; this is briefly described. A description of the internal structures used to model the data is given. The component programs of RAINBOW, in its present state of development, are listed and described. The paper concludes with some suggestions for improvements and extensions to the system.

INHIBITION OF THYROIDAL IODIDE CONCENTRATING BY TRIIODOTHYRONINE: EVIDENCE FOR AN EFFECT NOT DUE TO DEPRESSION OF THYROTROPHIN BUT DEPENDENT ON THE PITUITARY<sup>1</sup> (1959)

The thyroid/serum radioiodide concentration ratio (T/S) of rats receiving thiouracil (TU) was depressed to a significantly greater degree by treatment with triiodothyronine (T3) than by hypophysectomy. Differences in iodine intake did not account for this finding. T3 failed to lower the T/S (>6) of hypophysectomized rats which were given TU, whereas in unoperated rats on a TU regimen the same dose of T3 reduced the T/S to 1. It is concluded that in addition to its inhibiting effect on thyrotrophin production T3 can also interfere with thyroidal iodide concentrating by another mechanism involving the pituitary in a mediating or permissive capacity.
229: Umbilical cord blood transplantation for adult patients with chronic myeloid leukemia (2007)

Chronic myelogenous leukemia (CML) was primarily treated with HSCT until imatinib mesilate was shown to be effective and safe for patients with early chronic phase CML. However, patients who fail imatinib therapy due to disease progression or drug intolerance still require HSCT. Umbilical cord blood (UCB) has been an increasingly used source of hematopoietic stem cells for transplantation (HSCT) of patients with hematologic malignancies who lack a suitable sibling donor. We report here on 20 adult patients who underwent UCB transplantation (UCBT) for Ph+ CML at the University of Minnesota between 1998 and 2005. Patient received myeloablative (MA, n=12) or nonmyeloablative (NMA, n=8) conditioning, The median age was 46 y (r: 18-58), 12 (60%) were male, and median weight was 78 kg (r: 57-103), and 13 (65%) were CMV positive. The MA conditioning was Bu/Cy (n=2) Cy/TBI ± ATG (n=4), or Cy/Fludarabine(Flu)/TBI (n=6). The NMA conditioning was Bu/Flu/TBI (n=2) or Cy/Flu/TBI± ATG (n=6). Posttransplantation immunosuppression was CsA alone (n=1), CsA/methylprednisolone(MP) (n=5), or CsA/MMF (n=14). Eleven patients (55%) receive a double UCB graft. The highest HLA disparity of UCB units was 4/6 (n=13), 5/6 (n=5), and 6/6 (n=2). Six patients (30%) were in first chronic phase (CP1) and 14 (70%) were in accelerated phase (AP) CML. The median TNC dose infused was 2.9 × 107/kg (r:1.2-5.3) and median CD34 dose infused was 4.8 × 105/kg (r: 0.7-12.7). The median time from diagnosis to transplant was 24.5 months (r: 6.7-118.8), and the median follow-up of surviving patients was 2.9 yrs (r: 0.7-.7.0). There were no failures of neutrophil engraftment. In the MA setting median time to neutrophil engraftment was 21d (r:13-33), grade II-IV acute GVHD was 58% (95%CI, 28-88%), 1-yr transplant related mortality (TRM) 41% (95%CI, 13-69), 2-yr relapse rate 10% (95%CI, 0-26), and overall survival 58% (95%CI, 30-86). In the NMA setting median time to neutrophil engraftment was 13d (r:5-32), grade II-IV acute GVHD was 63% (95%CI, 28-98%), 1-yr transplant related mortality (TRM) 38% (95%CI, 6-70), 2-yr relapse rate 13% (95%CI, 0-34), and overall survival 50% (95%CI, 15-85). There was no statistically significant difference between MA and NMA conditioning regimens on all outcomes. In this report we show that UCB appears to be a safe and effective HSC for transplantation of patients with CML.

Bovine milk exosomes contain microRNA and mRNA and are taken up by human macrophages (2015)

We reported previously that microRNA (miRNA) are present in whey fractions of human breast milk, bovine milk, and rat milk. Moreover, we also confirmed that so many mRNA species are present in rat milk whey. These RNA were resistant to acidic conditions and to RNase, but were degraded by detergent. Thus, these RNA are likely packaged in membrane vesicles such as exosomes. However, functional extracellular circulating RNA in bodily fluids, such as blood miRNA, are present in various forms. In the current study, we used bovine raw milk and total RNA purified from exosomes (prepared by ultracentrifugation) and ultracentrifuged supernatants, and analyzed them using miRNA and mRNA microarrays to clarify which miRNA and mRNA species are present in exosomes, and which species exist in other forms. Microarray analyses revealed that most mRNA in milk whey were present in exosomes, whereas miRNA in milk whey were present in supernatant as well as exosomes. The RNA in exosomes might exert functional effects because of their stability. Therefore, we also investigated whether bovine milk-derived exosomes could affect human cells using THP-1 cells. Flow cytometry and fluorescent microscopy studies revealed that bovine milk exosomes were incorporated into differentiated THP-1 cells. These results suggest that bovine milk exosomes might have effects in human cells by containing RNA.
Finding highly correlated pairs efficiently with powerful pruning (2006)

We consider the problem of finding highly correlated pairs in a large data set. That is, given a threshold not too small, we wish to report all the pairs of items (or binary attributes) whose (Pearson) correlation coefficients are greater than the threshold. Correlation analysis is an important step in many statistical and knowledge-discovery tasks. Normally, the number of highly correlated pairs is quite small compared to the total number of pairs. Identifying highly correlated pairs in a naive way by computing the correlation coefficients for all the pairs is wasteful. With massive data sets, where the total number of pairs may exceed the main-memory capacity, the computational cost of the naive method is prohibitive. In their KDD'04 paper [15], Hui Xiong et al. address this problem by proposing the TAPER algorithm. The algorithm goes through the data set in two passes. It uses the first pass to generate a set of candidate pairs whose correlation coefficients are then computed directly in the second pass. The efficiency of the algorithm depends greatly on the selectivity (pruning power) of its candidate-generating stage.In this work, we adopt the general framework of the TAPER algorithm but propose a different candidate-generation method. For a pair of items, TAPER's candidate-generation method considers only the frequencies (supports) of individual items. Our method also considers the frequency (support) of the pair but does not explicitly count this frequency (support). We give a simple randomized algorithm whose false-negative probability is negligible. The space and time complexities of generating the candidate set in our algorithm are asymptotically the same as TAPER's. We conduct experiments on synthesized and real data. The results show that our algorithm produces a greatly reduced candidate set - one that can be several orders of magnitude smaller than that generated by TAPER. Because of this, our algorithm uses much less memory and can be faster. The former is critical for dealing with massive data.
Abstract 16223: Cardiac Arrhythmias in Hospitalized Patients With COVID-19 (2020)

Introduction: Arrhythmias have been reported frequent in COVID-19 patients, but the incidence and nature have not been well characterized. Hypothesis: Atrial and ventricular arrhythmias are common complications of patients with COVID-19. Methods: Patients admitted with COVID-19 and monitored by telemetry were prospectively enrolled in the study. Baseline characteristics, hospital course, treatment and complications were collected from the patients’ medical records. Telemetry was monitored to detect the incidence of cardiac arrhythmias. The incidence and types of cardiac arrhythmias were analyzed and compared between survivors and non-survivors. Results: Among 143 patients admitted with telemetry monitoring, overall in-hospital mortality was 23.1% (33/143 patients) during the period of observation (mean follow up 19.9 ± 13.7 days). Survivors were younger (68.1 ± 17.2 vs. 77.6 ± 15.9 years old, p=0.006), had higher body mass index (28.1 ± 8.3 vs. 24.3 ± 6.2, p=0.019), were less tachycardic on initial presentation (heart rate 90.6 ± 19.4 vs. 99.8 ± 23.7 bpm, p=0.026) and had lower troponin (peak troponin 0.03 vs. 0.14 ng/ml. p=0.006) and interleukin-6 levels (peak interleukin-6 32 vs. 264 pg/ml, p=0.001). Sinus tachycardia, the most common arrhythmia (occurring in 39.9% [57/143] of patients), occurred more frequently in non-survivors (57.6% vs. 34.5% in survivors, p=0.018). Premature ventricular complexes occurred in 28.7% (41/143), and non-sustained ventricular tachycardia in 15.4% (22/143) of patients, with no difference between survivors and non-survivors. Sustained ventricular tachycardia and ventricular fibrillation were rare (seen only in 1.4% and 0.7% of patients, respectively). Conclusions: In this prospective observational study of hospitalized and monitored patients with COVID-19, sinus tachycardia was the most common rhythm disorder, and its presence was associated with higher mortality. Sustained ventricular tachycardia or ventricular fibrillation were infrequent, contradicting previous reports that malignant ventricular arrhythmias are commonly seen in patients hospitalized with COVID-19.
Helping HPC Users Specify Job Memory Requirements via Machine Learning (2016)

Resource allocation in High Performance Computing (HPC) settings is still not easy for end-users due to the wide variety of application and environment configuration options. Users have difficulties to estimate the number of processors and amount of memory required by their jobs, select the queue and partition, and estimate when job output will be available to plan for next experiments. Apart from wasting infrastructure resources by making wrong allocation decisions, overall user response time can also be negatively impacted. Techniques that exploit batch scheduler systems to predict waiting time and runtime of user jobs have already been proposed. However, we observed that such techniques are not suitable for predicting job memory usage. In this paper we introduce a tool to help users predict their memory requirements using machine learning. We describe the integration of the tool with a batch scheduler system, discuss how batch scheduler log data can be exploited to generate memory usage predictions through machine learning, and present results of two production systems containing thousands of jobs.
Anhydrous aluminium nitrate, and the nitronium and alkylammonium tetranitratoaluminates (1966)

Conditions are described under which reaction of the 9-hydrate of aluminium nitrate with excess of dinitrogen pentoxide gives the 1 : 1 adduct Al(NO3)3,N2O5. The anhydrous nitrate can be obtained from this adduct by sublimation in a vacuum. The pentoxide bonds tenaciously to aluminium nitrate, and compounds Al(NO3)3,xN2O5(where O < x < 1) are usually the initial products. Reaction of aluminium bromide with chlorine nitrate, followed by sublimation, gave Al(NO3)3,0·4N2O5. The infrared spectrum of the 1 : 1 adduct identifies it as the salt (NO2+)[Al(NO3)4]–. This, and the salt (Et4N)[Al(NO3)4], are the first substantiated examples of the [Al(NO3)4]– ion. For the tetraethylammonium salt the infrared spectrum, the ultraviolet spectrum of solutions in acetonitrile, and the electrical conductivity of solutions in nitromethane are discussed.
Active Dust Mitigation Technology for Thermal Radiators for Lunar Exploration (2010)

Dust accumulation on thermal radiator surfaces planned for lunar exploration will significantly reduce their efficiency. Evidence from the Apollo missions shows that an insulating layer of dust accumulated on radiator surfaces could not be removed and caused serious thermal control problems. Temperatures measured at different locations in the magnetometer on Apollo 12 were 38 °C warmer than expected due to lunar dust accumulation. In this paper, we report on the application of the Electrodynamic Dust Shield (EDS) technology being developed in our NASA laboratory and applied to thermal radiator surfaces. The EDS uses electrostatic and dielectrophoretic forces generated by a grid of electrodes running a 2 μA electric current to remove dust particles from surfaces. Working prototypes of EDS systems on solar panels and on thermal radiators have been successfully developed and tested at vacuum with clearing efficiencies above 92%. For this work, EDS prototypes on flexible and rigid thermal radiators were developed and tested at vacuum.
Real-Time Measurements of Ultrafast Spontaneous Modulation Instability in Optical Fiber (2017)

Efficacy and Ease of Use of an Intravenous Catheter Designed to Prevent Blood Leakage: A Prospective Observational Trial (2015)

The investigational IV catheter effectively prevented blood leakage, thereby reducing contamination risk and workload associated with cleaning. Omission of vein compression facilitated and shortened IV catheter placement.
Stability of Frozen Milk (1961)

Summary Lactose crystallization apparently has a nonlinear relation with the volume of the casein precipitate. A study showed that the caseinate system suddenly destabilized when 85 to 90% of the lactose was in the alpha form. The time required to reach this critical stage was longer when samples contained sucrose, but not so when they contained sorbitol. The inhibiting effect of sucrose addition was attributed to retardation of the rate of lactose crystallization. Seeding greatly accelerated lactose crystallization in all samples, resulting in earlier destabilization. For study of any changes taking place in the serum and casein-bound phosphorus, the milk from a cow injected with P 32 was separated, condensed, and stored at 12°F. A slight progressive increase in the total P as well as P 32 contents of the serum indicates that bound phosphorus was slowly dissociated from the casein micelles into the serum, but it would be difficult to prove whether this is a cause or an effect of the destabilization reaction.
Dependence of Photoresist and Etch Residue Removal on CO<sub>2</sub> Pressure in Alcohol-Based Gas-Expanded Liquids (2006)

With rapid technology development of integrated circuits, new challenges arise. Current liquid based removal chemistries are limited by continuous decrease in feature devices as well by their hazardous nature. Gas expanded liquids (GXLs) and supercritical fluids may offer a more environtmentally benign alternative. The GXL formulated by CO2 expanded ethanol (up to 75 mole % CO2) removed PHOST (polyhydroxystyrene) photoresist film indicating that the inclusion of CO2 does not inhibit photoresist removal. In situ interferometry measurements of the PHOST layers generated insight into the removal mechanism. The GXL CO2 expanded TMAHCO3/CH3OH at a temperature of 90oC and pressures above 1000 psig removed photoresist and post plasma etch residue. Cleaning efficiency depended upon CO2 pressure; at low pressures the CO2 reduced the mole fraction of the TMAHCO3/CH3OH while at higher pressures the CO2 assisted removal.
Dynamic features of combustion (1985)

Abstract The dynamic features of combustion arise from the evolution of exothermic energy and its deposition in the essentially compressible medium in which the process takes place. These features are exposed in representative cases that cover a wide spectrum of combustion phenomena, namely ignition, flame propagation, explosion, and detonation. Ignition and explosion are treated as problems in nonlinear mechanics dynamic properties of the system. Consideration of the turbulent flame propagation where the transformation to phase coordinates is instrumental in revealing the mechanism introduces a fascinating branch of combustion science: the aerodynamics of flames, a time-dependent treatment of the flow field where the unburnt and burnt mixtures are considered as incompressible media separated by an interface representing the flame front. The account of detonation phenomena is restricted to just the phenomenological aspects of their development and structure, illustrating vividly most of the dynamic features of combustion. Since they display the mechanism of feedback exerted by the combustion process on the flow field of the reacting medium, their study should be of particular significance to the development of controlled combustion systems: one of the most exciting prospects for energy conversion technology.
Matrix infrared spectra of NUN formed by the insertion of uranium atoms into molecular nitrogen (1993)

Pulsed-laser ablated uranium atoms were codeposited with 14N2(15N2) and excess Ar at 12 K. The Fourier transform infrared (FTIR) spectrum revealed a single product, UN2, which exhibited a ν3 absorption at 1051.0 cm−1. Ultraviolet (UV) photolysis increased the yield of UN2 by threefold and showed that electronic excitation facilitated the insertion reaction. N2 perturbed UN2 bands at 1041.3 and 1031.5 cm−1 grew sharply during matrix annealings. In 14N15N experiments the ν1 and ν3 modes of 14NU15N were observed at 987.2 and 1040.7 cm−1, respectively; FG matrix calculations were performed to determine Fr=8.27 mdyn/Å and Frr=0.12 mdyn/Å and to estimate the IR-inactive ν1 modes of U14N2 and U15N2 at 1008.3 and 985.7 cm−1, respectively. Energetic considerations suggest that the U+N2 insertion reaction has little exothermicity and that the activation energy for this reaction may be provided by hypothermal uranium atoms.
