Highly Robust, Flexible, and Large‐Scale 3D‐Metallized Sponge for High‐Performance Electromagnetic Interference Shielding (2019)

Abstract Electromagnetic interference (EMI) is a type of pollution that is caused by the ubiquitous usage of electronic communication in general, and military radar equipment in particular. Even though this is a common problem for a long time, the fabrication of large‐area, flexible, and robust EMI shielding materials is still a challenge today. In this work, the 3D meshing strategy is simulated for most efficient utilization of metallic silver for X‐band EMI shielding, and propose a roll‐to‐roll (R2R) process to fabricate robust, flexible, and large‐scale EMI shielding sponge, silver nanowires/polyvinyl butyral (PVB) melamine sponge (AgPMS). Typically, 0.5 cm thick sponge has about 60 dB total EMI shielding efficiency (SE) in the microwave band, which is higher than for commercial EMI shielding sponges (about 45 dB) of the same thickness. AgPMS shows unchanged electrical properties after 1000 compression and bending cycles. Moreover, a AgPMS garment is made to demonstrate the excellent EMI shielding performance and remarkable flexibility of this material. Those properties suggest that AgPMS can be readily applied in challenging environments like hospitals, military installations, remote communication centers, and for any devices with curved surfaces.

Modifiable Predictors Associated with Having a Gestational Weight Gain Goal (2020)

The goal of this paper was to determine predictors of having a weight gain goal in early pregnancy. In 2008, we administered a 48-item survey to 249 pregnant women attending obstetric visits. We examined predictors of women having a goal concordant or discordant with 1990 Institute of Medicine (IOM) guidelines, vs. no goal, using binary and multinomial logistic regression. Of the 292 respondents, 116 (40%) had no gestational weight gain goal, 112 (39%) had a concordant goal and 61 (21%) had a goal discordant with IOM guidelines. Predictors of a guideline-concordant goal, vs. no goal, included sugar sweetened beverage consumption < vs. ≥ 1 serving per week (OR = 2.4, 95%CI: 1.1, 5.7), physical activity ≥ vs. <2.5 h per week (OR = 3.6, 95%CI: 1.7, 7.5), agreeing that `I tried to keep weight down not to look pregnant' (OR = 14.3, 95%CI: 1.4, 140.5). Other predictors only of having a discordant goal (vs. no goal) included agreeing that `as long as I am eating well, I don't care how much I gain' (OR = 0.3, 95%CI: 0.2, 0.8) and agreeing that `if I gain too much weight one month, I try to keep from gaining the next' (OR = 4.1, 95%CI: 1.6, 10.4). Women whose doctors recommended weight gains consistent with IOM guidelines were more likely to have a concordant goal (vs. no goal) (OR = 5.3, 95%CI: 1.5, 18.6). Engaging in healthy behaviors and having health providers offer IOM weight gain recommendations may increase the likelihood of having a concordant gestational weight gain goal, which, in turn, is predictive of actual weight gains that fall within IOM guidelines.
Personal Social Networks and Relapses in Women With Substance Dependence: Application of the Theory of Planned Behavior (2022)

Our findings support that personal social network characteristics can be considered as subjective norms in the TPB model. Personal social network interventions focusing on rebuilding consistent social norms against drug-using behaviors may decrease intention to use substance, which will lead to abstinence.
Variable-aperture calorimeter for an unstable resonator. Interim report (1976)

A new technique for measuring the output power from a cw edge-coupled unstable resonator has been developed and applied to a cw DF laser. An internal-cavity calorimeter was used that permits measurement of output power with a variable rectangular-mode geometry while containing the radiation inside the resonator. The variable aperture calorimeter-absorbing scraper (VACAS) device consists of an absorbing copper plate calorimeter assembly, which replaces the 45-deg output coupling mirror of a conventional edge-coupled unstable cavity.
Analytics for an Online Retailer: Demand Forecasting and Price Optimization (2015)

We present our work with an online retailer, Rue La La, as an example of how a retailer can use its wealth of data to optimize pricing decisions on a daily basis. Rue La La is in the online fashion sample sales industry, where they offer extremely limited-time discounts on designer apparel and accessories. One of the retailer’s main challenges is pricing and predicting demand for products that it has never sold before, which account for the majority of sales and revenue. To tackle this challenge, we use machine learning techniques to estimate historical lost sales and predict future demand of new products. The nonparametric structure of our demand prediction model, along with the dependence of a product’s demand on the price of competing products, pose new challenges on translating the demand forecasts into a pricing policy. We develop an algorithm to efficiently solve the subsequent multiproduct price optimization that incorporates reference price effects, and we create and implement this algorithm into a pricing decision support tool for Rue La La’s daily use. We conduct a field experiment and find that sales does not decrease because of implementing tool recommended price increases for medium and high price point products. Finally, we estimate an increase in revenue of the test group by approximately 9.7% with an associated 90% confidence interval of [2.3%, 17.8%].
Identification and structural characterization of steroidal glycosides in Hoodia gordonii by ion‐trap tandem mass spectrometry and liquid chromatography coupled with electrospray ionization time‐of‐flight mass spectrometry (2008)

Electrospray ion-trap tandem mass spectrometry (ESI-MS/MS) and high-performance liquid chromatography coupled with electrospray ionization time-of-flight mass spectrometry (LC/ESI-TOFMS) were used to identify and characterize eight C-21 steroidal glycosides in Hoodia gordonii. A generalized fragmentation pathway was proposed by comparing the spectra acquired for eight C-21 steroidal glycosides. The steroidal glycosides in Hoodia gordonii have been classified into two major core groups: hoodigenin A and calogenin. Using the ESI-TOF method, the major core peak ions generated by hoodigenin A glycosides are m/z 313 and 295 and by calogenin glycosides are m/z 479, 461, 299 and 281, respectively. In the MS/MS spectra, fragmentation reactions of the [M+Na](+) ion were recorded to provide structural information about the glycosyl and aglycone moieties. The data illustrates the ability of positive mode ESI for the identification of hoodigenin A and calogenin glycosides, including the nature of the hoodigenin A and calogenin core, the number of sugar residues and the type of saccharide moiety.

Liver-Directed Therapy for Hepatic Metastases in Patients Undergoing Pancreaticoduodenectomy (2010)

Pancreaticoduodenectomy plus liver-directed therapy is associated with considerable morbidity. The incidence of hepatic abscess is increased in patients undergoing staged pancreaticoduodenectomy followed by liver-directed therapy.
Major Changes in the Kinetic Mechanism of AMP Inhibition and AMP Cooperativity Attend the Mutation of Arg49 in Fructose-1,6-bisphosphatase (1997)

The significance of subunit interface residues Arg49 and Lys50 in the function of porcine liver fructose-1,6-bisphosphatase was explored by site-directed mutagenesis, initial rate kinetics, and circular dichroism spectroscopy. The Lys50 --> Met mutant had kinetic properties similar to the wild-type enzyme but was more thermostable. Mutants Arg49 --> Leu, Arg49 --> Asp, Arg49 --> Cys were less thermostable than the wild-type enzyme yet exhibited wild-type values for kcat and Km. The Ki for the competitive inhibitor fructose 2,6-bisphosphate increased 3- and 5-fold in Arg49 --> Leu and Arg49 --> Asp, respectively. The Ka for Mg2+ increased 4-8-fold for the Arg49 mutants, with no alteration in the cooperativity of Mg2+ binding. Position 49 mutants had 4-10-fold lower AMP affinity. Most significantly, the mechanism of AMP inhibition with respect to fructose 1,6-bisphosphate changed from noncompetitive (wild-type enzyme) to competitive (Arg49 --> Leu and Arg49 --> Asp mutants) and to uncompetitive (Arg49 --> Cys mutant). In addition, AMP cooperativity was absent in the Arg49 mutants. The R and T-state circular dichroism spectra of the position 49 mutants were identical and superimposable on only the R-state spectrum of the wild-type enzyme. Changes from noncompetitive to competitive inhibition by AMP can be accommodated within the framework of a steady-state Random Bi Bi mechanism. The appearance of uncompetitive inhibition, however, suggests that a more complex mechanism may be necessary to account for the kinetic properties of the enzyme.

Carbon nitride oligomers derived from the covalent triazine framework CTF-1 constitute a new generation of tunable hydrogen evolution photocatalysts, which show moderate activities even without the addition of a co-catalyst.
Elimination of Cholesterol Ester from Macrophage Foam Cells by Adenovirus-mediated Gene Transfer of Hormone-sensitive Lipase (2002)

Cholesterol ester (CE)-laden foam cells are a hallmark of atherosclerosis. To determine whether stimulation of the hydrolysis of cytosolic CE can be used as a novel therapeutic modality of atherosclerosis, we overexpressed hormone-sensitive lipase (HSL) in THP-1 macrophage-like cells by adenovirus-mediated gene delivery, and we examined its effects on the cellular cholesterol trafficking. We show here that the overexpression of HSL robustly increased neutral CE hydrolase activity and completely eliminated CE in the cells that had been preloaded with CE by incubation with acetylated low density lipoprotein. In these cells, cholesterol efflux was stimulated in the absence or presence of high density lipoproteins, which might be at least partially explained by the increase in the expression of ABCA1. Importantly, these effects were achieved without the addition of acyl-CoA:cholesterol acyltransferase inhibitor, cAMP, or even high density lipoproteins. Furthermore, the uptake and degradation of acetylated low density lipoprotein was significantly reduced probably by decreased expression of scavenger receptor A and CD36. Notably, the cells with stimulated CE hydrolysis did not exhibit either buildup of free cholesterol or cytotoxicity. In conclusion, increased hydrolysis of CE by the overexpression of HSL leads to complete elimination of CE from THP-1 foam cells not only by increasing efflux but also by decreasing influx of cholesterol.
Template‐free ribosomal synthesis of polypeptides from aminoacyl‐tRNA (1986)

Misacylated phenylalanyl-tRNALys, just as lysyl-tRNALys, but not phenylalanyl-tRNAPhe, have been shown to serve as substrates for ribosomal synthesis of polypeptides (polyphenylalanine and polylysine, respectively) in the absence of a template polynucleotide (poly(A)). The conclusion was made that it is the structure of tRNA that determines the ability of the aminoacyl-tRNALys to participate in peptide elongation on ribosomes without codon-anticodon interactions.

Idletime scheduling with preemption intervals (2005)

This paper presents the idletime scheduler; a generic, kernel-level mechanism for using idle resource capacity in the background without slowing down concurrent foreground use. Many operating systems fail to support transparent background use and concurrent foreground performance can decrease by 50% or more. The idletime scheduler minimizes this interference by partially relaxing the work conservation principle during preemption intervals , during which it serves no background requests even if the resource is idle. The length of preemption intervals is a controlling parameter of the scheduler: short intervals aggressively utilize idle capacity; long intervals reduce the impact of background use on foreground performance. Unlike existing approaches to establish prioritized resource use, idletime scheduling requires only localized modifications to a limited number of system schedulers. In experiments, a FreeBSD implementation for idletime network scheduling maintains over 90% of foreground TCP throughput, while allowing concurrent, high-rate UDP background flows to consume up to 80% of remaining link capacity. A FreeBSD disk scheduler implementation maintains 80% of foreground read performance, while enabling concurrent background operations to reach 70% throughput.

On the Sphere Decoding Complexity of STBCs for Asymmetric MIMO Systems (2011)

In the landmark paper by Hassibi and Hochwald, it is claimed without proof that the upper triangular matrix R encountered during the sphere decoding of any linear dispersion code is full-ranked whenever the rate of the code is less than the minimum of the number of transmit and receive antennas. In this paper, we show that this claim is true only when the number of receive antennas is at least as much as the number of transmit antennas. We also show that all known families of high rate (rate greater than 1 complex symbol per channel use) multigroup ML decodable codes have rank-deficient R matrix even when the criterion on rate is satisfied, and that this rank-deficiency problem arises only in asymmetric MIMO with number of receive antennas less than the number of transmit antennas. Unlike the codes with full-rank R matrix, the average sphere decoding complexity of the STBCs whose R matrix is rank-deficient is polynomial in the constellation size. We derive the sphere decoding complexity of most of the known high rate multigroup ML decodable codes, and show that for each code, the complexity is a decreasing function of the number of receive antennas.
History and impact of RDP (2014)

The Ribosomal Database Project (RDP) grew out of Carl Woese's vision of how rRNA comparative methods could transform biology. First at the University of Illinois Urbana-Champaign, and later at Michigan State University's Center for Microbial Ecology, the project has grown from a few hundred to several million rRNA gene sequences. In the years since Woese started the RDP, publications describing the database and related tools have been cited over 11,000 times in journals spanning a wide range of disciplines, while the RDP website is accessed by 10,000 researchers in over 20,000 analysis sessions each month. This article describes the history of RDP's development over the last two decades.
Analysis of Toll Discounts on Nationwide Expressway in Japan (2020)

As for the expressway toll, deployment of the Electronic Toll Collection (ETC) system enabled setting various toll levels by time of the day. A variety of toll discounts have been applied to tackle with road transport issues and for economic stimulation. For expressways managed by Japan’s three expressway companies (NEXCO Central, NEXCO East and NEXCO West), this study performs 1) elucidation of the change in the traffic conditions, user properties, etc. associated with toll discounts by means of traffic data, ETC user data, etc., 2) traffic assignment simulations for the nationwide road network, and 3) grasping of the effects of each toll discount through consumer surplus analysis using the simulation results.

In Plane Mechanical Properties of Tetrachiral and Antitetrachiral Hybrid Metastructures (2017)

A novel tetrachiral and antitetrachiral hybrid metastructure is proposed, and its in-plane mechanical properties are studied through strain energy analysis. Based on rigid ring rotation assumption, the analytical expression for the in-plane modulus of anisotropic tetrachiral and antitetrachiral hybrid metastructure is derived, and in-plane tensile experimental test and finite element simulation are performed and compared with the theoretical models. The corresponding in-plane anisotropic mechanical properties can be tuned with three independent dimensionless geometrical parameters, and effects of dimensionless geometrical parameters on the in-plane mechanical properties are studied systematically. Finally, an innovative tetrachiral and antitetrachiral hybrid metastructure stent is designed, and its mechanical behaviors under uniaxial tensile loading are investigated. It is found that the designed tetrachiral and antitetrachiral hybrid stent shows negative Poisson ratio properties, and the axial and circumferential deformation can be controlled through adjusting the spacing of unit cell along axial and circumferential directions.
The Application of Friedländer and Fischer Methodologies to the Synthesis of Organized Polyaza Cavities (1992)

The Friedländer reaction of β-aminoacrolein and ortho-aminoarenealdehydes and ortho-aminoheteroarenealdehydes with cyclic ketones and diketones provides a variety of polyaza cavity-shaped molecules. The conformation of the cavity is governed by the size of the ring containing the carbonyl group and the orientation of two carbonyls with respect to one another. Diaminodialdehydes and appropriate synthons can also be used to elaborate this approach. Alternatively, bridged terpyridines are also accessible through the reaction of an enamine with formaldehyde or an aromatic aldehyde. Analogous 2-(2′-pyridyl)indole systems can be prepared by an application of the Fischer indole synthesis to the same cyclic ketones while the use of 8-hydrazinoquinoline provides access to the pyrido[2,3-g]indole subunit. 1.

Improved optical transmission of KTiOPO4 crystals through cerium-doping and oxygen annealing (1992)

KTiOPO4 single crystals were grown from cerium-doped potassium phosphate fluxes. Cerium-doped crystals exhibited increased optical transmission relative to undoped material from the UV band edge to roughly 800 nm. Oxygen annealing was performed on undoped and cerium-doped crystals. The effects on transmission of oxygen annealing were qualitatively similar to those brought about by cerium doping although roughly five times smaller in magnitude. Cerium doping had no observable influence on the nonlinear optical coefficients but altered slightly the crystal’s birefringence.
An animal model for in vivo evaluation of tumor glycolytic rates with positron emission tomography (1993)

We developed a method for evaluating tumor glycolytic rates in vivo with nude mice injected with 2-[F-18]fluoro-2-deoxy-D-glucose (FDG) and a dedicated animal positron emission tomography (PET) scanner. Animals were injected with NR-6 mouse fibroblast tumor cell lines. When tumors achieved a large enough size to be macroscopically visible, quantitative measurements of FDG uptake in vivo were obtained, using both standard nonlinear regression with the FDG tracer kinetic model to generate estimates of model parameters, including KNLR, the rate constant for net phosphorylation of FDG. Additionally, we determined the values of KPAT, the rate constant for net phosphorylation of FDG measured with a non-iterative graphical method. Estimates of K were highly correlated (r = 0.95) with both methods, and parametric images of KPAT demonstrate both the tumor location and size, but are also scaled in units of phosphorylation of FDG. The method is suitable for serial studies of tumor glucose metabolism during and after therapeutic interventions, such as chemotherapeutic trials.
2518 Development of Automatically Processing and Assembling System to Manufacture Various Kinds of Products by Virtual Transmission of Information (2005)

The switch module automatic operation processing assembly system that crowded and achieved a high yield, stock-less, and the shortest lead time for many varieties by manufacturing various kinds of products method assumed that the flow in the diverse-types-and-small-quantity production age was received, crowded, the connection between the quality conclusion, the model group same equipment, and the process and synchronization assumed to be a concept while needs of manufacturing various kinds of products increased, and the difficulty high was developed. Especially, arrangements (arrangements substitution-less) in the automatic operation were achieved for many varieties, the medium such as RFID was not used to transmit product instruction information that became the backbone, and the effect such as making of equipment a low cost was achieved by adopting the virtual information transmission method.
