Comparison of enrofloxacin and ceftiofur sodium for the treatment of relapse of undifferentiated fever/bovine respiratory disease in feedlot cattle. (2012)

This commercial field trial compared the efficacy of enrofloxacin and ceftiofur sodium in beef cattle at high risk of developing undifferentiated fever (UF), also known as bovine respiratory disease (BRD) that received tilmicosin at feedlot arrival, were diagnosed and initially treated for UF with tilmicosin, and subsequently required a second UF treatment (first relapse). Feedlot cattle (n = 463) were randomly assigned to 2 experimental groups: ENRO or CEF. Second UF relapse, 3rd UF relapse, overall case fatality and BRD case fatality rates were lower in the ENRO group than in the CEF group (P < 0.05). There were no differences in average daily gain (allocation to re-implant date), chronicity, histophilosis case fatality or miscellaneous case fatality rates between the groups (P ≥ 0.05). A per-animal economic advantage of Can$57.08 was calculated for the ENRO group versus the CEF group. In feedlot cattle in western Canada at high risk of developing UF, it was more cost effective to administer enrofloxacin than ceftiofur sodium for treatment of UF relapse.

Oxidation of Glycerol with Unactivated Electroless CuNiMoP Catalyst (2017)

Unannealed CuNiMoP electrocatalyst was found active in electrochemical oxidation of glycerol, providing over 60% conversion without optimization. Prompted by this result, the same catalyst was investigated for the thermochemical oxidation of glycerol. For the thermochemical oxidation of glycerol using the as-deposited electroless CuNiMoP catalyst, a 23 full factorial design of experiments (two level factorial experiment design with three factors) to assess the influence of temperature (A), reaction time (B) and pressure (C). The major reaction products detected by high performance liquid chromatography (HPLC) were glyceric, hydroxypyruvic, tartronic, oxalic and formic acids. The factors found to be most significant for the production of glyceric and tartronic acids were A, B, C, AB and BC. The highest percent conversion obtained for 30-min and 60-min catalysts was 10.6% and 9.4%, respectively. The presence of lactic acid was observed only for the 60-min as-deposited electroless CuNiMoP/Al2O3 catalyst. The results suggest the feasibility of an inexpensive catalyst based on non-noble metals for the thermochemical oxidation of glycerol through the electroless deposition technique. Some differences exist between the thermochemical and electrochemical product selectivity of the CuNiMoP catalyst, and reasons are suggested for the observed differences.
Process challenges and solutions for embedding Chip-On-Board into mainstream SMT assembly (2003)

The fundamentals of the Chip-On-Board (COB) process imply attaching the chip (die) in place and wire bonding it directly to the substrate metalization alongside other surface mount devices attached by standard SMT processes. In essence, the packaging and testing task transfers from the IC backend process to the SMT board assembly shop. The process significantly improves footprint efficiency, cutting cost and lead-time. COB technology includes variants such as Chip-On-Flex or on other substrates. COB technology is at work in many routine day to day products but process information has remained somewhat limited in the mainstream Surface Mount world possibly because wire bonding has more in common with IC backend processes than traditional surface mount assembly. Merging COB into mainstream surface mount processes has usually entailed acquiring the specialized know-how through considerable 'hands-on' experimentation. This paper provides the required information on all aspects of the COB process from applications, positioning, costs, die selection, layout, process options, equipment and rework for implementing COB processes into existing SMT lines and manage COB yields. Based on real life examples, the paper covers the key considerations, major critical factors and the challenges for a successful COB-SMT merge.
Pain relief produces negative reinforcement through activation of mesolimbic reward–valuation circuitry (2012)

Relief of pain is rewarding. Using a model of experimental postsurgical pain we show that blockade of afferent input from the injury with local anesthetic elicits conditioned place preference, activates ventral tegmental dopaminergic cells, and increases dopamine release in the nucleus accumbens. Importantly, place preference is associated with increased activity in midbrain dopaminergic neurons and blocked by dopamine antagonists injected into the nucleus accumbens. The data directly support the hypothesis that relief of pain produces negative reinforcement through activation of the mesolimbic reward-valuation circuitry.
Current Status and Future Prospects of Copper Oxide Heterojunction Solar Cells (2016)

The current state of thin film heterojunction solar cells based on cuprous oxide (Cu₂O), cupric oxide (CuO) and copper (III) oxide (Cu₄O₃) is reviewed. These p-type semiconducting oxides prepared by Cu oxidation, sputtering or electrochemical deposition are non-toxic, sustainable photovoltaic materials with application potential for solar electricity. However, defects at the copper oxide heterojunction and film quality are still major constraining factors for achieving high power conversion efficiency, η. Amongst the Cu₂O heterojunction devices, a maximum η of 6.1% has been obtained by using pulsed laser deposition (PLD) of Al<i><sub>x</sub></i>Ga<sub>1-<i>x</i></sub>O onto thermal Cu₂O doped with Na. The performance of CuO/n-Si heterojunction solar cells formed by magnetron sputtering of CuO is presently limited by both native oxide and Cu rich copper oxide layers at the heterointerface. These interfacial layers can be reduced by using a two-step sputtering process. A high η of 2.88% for CuO heterojunction solar cells has been achieved by incorporation of mixed phase CuO/Cu₂O nanopowder. CuO/Cu₂O heterojunction solar cells fabricated by electrodeposition and electrochemical doping has a maximum efficiency of 0.64% after surface defect passivation and annealing. Finally, early stage study of Cu₄O₃/GaN deposited on sapphire substrate has shown a photovoltaic effect and an η of ~10<sup>-2</sup>%.
ELECTRON TRANSFER REACTIONS OF METAL CARBONYL ANIONS (1994)

Abstract Metal carbonyl anions exhibit one- and two-electron reactions. The two-electron processes involving transfer of groups (hydrogen, alkyl, and halogen) between metal centers are related to the nucleophilicity. The one-electron processes are primarily outer-sphere electron transfer for the metal carbonyl anions. These reactions are observed in the presence of oxidants such as coordination complexes, pyridinium salts, metal carbonyl dimers and metal carbonyl clusters. However, in contrast to organic reactions, the metal carbonyl anions may undergo inner-sphere electron transfer. Reactions of metal carbonyl anions of low nucleophilicity with metal carbonyl cations or halides are best interpreted as inner-sphere, one-electron transfer.
Statistical Prediction of Donor-Acceptor Thiophene Copolymer Properties (2019)

This work illustrates some of the shortcomings of the standard donor-acceptor model as a tool for predicting polymer molecular orbital interactions. 8741 DFT calculations were performed for a series of co-oligomers of varying length from a diverse set of 91 thiophene monomers to explore statistical relationships between the frontier molecular orbital energies of oligomers and their degree of polymerization. These relationships were used to develop predictive models that allow for the calculation of polymer frontier molecular orbital energies. Polymer frontier molecular orbital energies have been shown to impact the device performances of many types of optoelectronic devices, including organic field effect transistors, organic photovoltaics and organic light emitting diodes.
A design strategy to match the band gap of periodic and aperiodic metamaterials (2020)

The focus of this paper is on elastic metamaterials characterised by the presence of wide sub-wavelength band gap. In most cases, such mechanical property is strictly connected to the periodic repetition of the unit cell. Nonetheless, the strict periodicity requirement could represent a drawback. In this paper, we present a design strategy for aperiodic elastic metamaterials in order to achieve the same performances as for the periodic counterparts. This is done by exploiting the concept of separation of modes for different building blocks, arranged in aperiodic fashion. A theoretical explanation is provided, as well as numerical simulations; the concept is validated by means of a set of experimental tests on prototypes that are realized via additive manufacturing.

Treatment with Sulfatide or its Precursor, Galactosylceramide, Prevents Diabetes in NOD Mice (2001)

Sulfatide (3'sulfogalactosylceramide) is a glycosphingolipid present within the nervous system and in the islets of Langerhans. Anti-sulfatide antibodies have been observed in both pre-diabetic and newly diagnosed type 1 diabetic patients. The aim of this study was to test in vivo, the therapeutic effect of sulfatide on the development of diabetes in the NOD mouse. In four separate experiments diabetogenic splenocytes from newly diabetic NOD mice were injected iv into 7-8 week old irradiated (700R) female NOD mice (4-10 million cells/mouse). Each experiment consisted of four treatment groups to which the mice were randomly divided: 1) sulfatide; 2) galactosylceramide (the precursor to sulfatide without sulfate); 3) GM1, a glycosphingolipid negatively charged as sulfatide but with a different sugar composition; and 4) phosphate buffered saline (PBS). The mice received 100 microg glycosphingolipid iv on the day of cell transfer and 1-3 times thereafter at four day intervals, and were screened for diabetes three times a week the next 52 days. Among all the 35 sulfatide-treated mice 54% became diabetic compared to 93 % of 43 PBS-treated animals (p < 0.00001). Correspondingly, galactosylceramide reduced diabetes incidence to 52% (25 mice, p < 0.00001). On the other hand, 86% of GM1-treated mice (n=28) became diabetic indicating that no effect was obtained by this glycosphingolipid. In two experiments in which less spleen cells were transferred (4-5 mill.) and glycosphingolipids were given 4 times, 35% of the sulfatide-treated animals (n = 17) developed diabetes compared to 85% of PBS-treated mice (n = 20, p < 0.001). A robust proliferative response to sulfatide, but none to GM1, was observed when spleen cells were rechallenged with glycosphingolipid in vitro. Thus, like insulin and GAD, sulfatide is able to prevent diabetes in NOD mice.
On Qualitative and Quantitative Reasoning in Validity (2009)

Beginning in the fall of 2001, the Spencer Foundation sponsored an interdisciplinary initiative seeking to expand the foundations of educational assessment. In a series of meetings and essays, the “Idea of Testing” Project (IOT) addressed the theories and methods through which educational assessment is conceptualized, practiced, and evaluated. The project organizers were Pamela Moss (University of Michigan), Diana Pullin (Boston College), James Gee (University of Wisconsin), and Edward Haertel (Stanford University). The working group additionally included King Beach (Florida State University), James Greeno (University of Pittsburgh and Stanford University), Carol Lee (Northwestern University), Hugh (Bud) Mehan (University of California, San Diego), Robert Mislevy (University of Maryland), Fritz Mosher (consultant to the Spencer Foundation), and Lauren Young (Spencer Foundation). The focus of the conversations was the intersection between assessment and opportunity to learn, with particular attention to the implications of a situative/ sociocultural perspective on learning for the practice of assessment.
30.3% PAE HBT Doherty power amplifier for 2.5&#x223C;2.7 GHz mobile WiMAX (2010)

The Doherty power amplifier for mobile WiMAX application is fully integrated in 1.2×1.2 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> using a 2-μm InGaP/GaAs HBT process. The direct input power dividing technique is employed on a chip. Broadband input and output matching techniques are used for broadband Doherty operation. A 1.5 times larger peaking amplifier than carrier amplifier is used to have high efficiency for IEEE 802.16e m-WiMAX signal, which has 9.6 dB crest factor and 8.75 MHz bandwidth. The PA with a supply voltage of 3.4 V has an EVM of 2.3% and a PAE of 31.5% at an output power of 24.75 dBm and an operating frequency of 2.6 GHz. The PAE of over 30.3% and the output power of over 24.6 dBm with the EVM of lower than 3.15% and the gain variation of 0.2 dB are achieved across 2.5~2.7 GHz without any assistant technique for linearization.
Compact and portable quantum sensor module using diamond NV centers (2023)

Abstract We developed a compact and portable measuring instrument using diamond NV centers that operates on the USB 3.0 power supply of a laptop computer. Its portability is achieved by the low power consumption of the optics, realized by the diamond corner cube that enhanced the current of the photodiode to 2.1 times higher than that of the planar diamond, and that of the microwave source, reduced by 20 dB, which was realized by a microwave resonator using a λ /4 open stub that strongly magnetically drives the NV center. These results contribute to the social implementation of diamond sensors.
The genomic origins of asthma (2014)

Lung function tracks from the earliest age that it can be reliably measured. Genome wide association studies suggest that most variants identified for common complex traits are regulatory in function and active during fetal development. Fetal programming of gene expression during development is critical to the formation of a normal lung. An understanding of how fetal developmental genes related to diseases of the lungs and airways is a critical area for research. This review article considers the developmental origins hypothesis, the stages of normal lung development and a variety of environmental exposures that might influence the developmental process: in utero cigarette smoke exposure, vitamin D and folate. We conclude with some information on developmental genes and asthma.
Schematic of mean thickness distribution on the lateral aspect of the canine frontal sinus as an experimental model of sinus surgery (2018)

The dog frontal sinus may represent an alternative model dental implant research; its topographical resemblance to the maxillary sinus renders it a potentially favorable experimental environment. The aim of this study was thus to elucidate the anatomical configuration of the canine frontal sinus and histological characteristics, and to determine whether it could be a new canine experimental model for dental implant research. Twenty-four sides of canine frontal bones were harvested. The distance from the nasion to the emerging point of the lateral aspect of the canine frontal sinus was measured with the aid of Lucion software. The thicknesses of the canine frontal sinus wall were measured, and the two specimens stained with hematoxylin and eosin. The mean distance from the nasion to the emerging point of the lateral aspect of the canine frontal sinus was 16.0 mm. The mean thicknesses of the canine frontal bone at 3, 6, 9, 12, and 15 mm lateral to the midsagittal plane were 2.3, 2.7, 3.2, 3.8, and 3.7 mm, respectively. The canine frontal sinus was lined with pseudostratified ciliated columnar epithelium. These data suggest that the canine frontal sinus is a suitable alternative to the canine maxillary sinus as a model for studying various sinus augmentation protocols.
IFN-γ-Dependent Recruitment of Mature CD27high NK Cells to Lymph Nodes Primed by Dendritic Cells (2008)

NK cells have been proposed to be an initial source of IFN-gamma that supports either Th1 or CTL priming. Although NK cells reside in naive lymph nodes (LN) at a very low frequency, they can be recruited into LN draining sites of infection, inflammation, or immunization where they potentially influence adaptive immunity. In this study, we report that mature CD27(high) NK cells are predominantly recruited into the draining LN following dendritic cell (DC) challenge. Importantly, the recruitment of the CD27(high) NK cell subset in the draining LN was dependent on host IFN-gamma and the activation status of NK cells. Endogenous epidermal DC migration induced by hapten challenge also triggers NK cell recruitment to the draining LN in an IFN-gamma-dependent mechanism. Thus, our results identify that CD27(high) NK cells are the dominant population recruited to the draining LN and NK cell recruitment requires endogenous IFN-gamma in coordinating with DC migration.
Wake-up effects in Si-doped hafnium oxide ferroelectric thin films (2013)

Hafnium oxide based ferroelectric thin films have shown potential as a promising alternative material for non-volatile memory applications. This work reports the switching stability of a Si-doped HfO2 film under bipolar pulsed-field operation. High field cycling causes a “wake-up” in virgin “pinched” polarization hysteresis loops, demonstrated by an enhancement in remanent polarization and a shift of negative coercive voltage. The rate of wake-up is accelerated by either reducing the frequency or increasing the amplitude of the cycling field. We suggest de-pinning of domains due to reduction of the defect concentration at bottom electrode interface as origin of the wake-up.
Isolation and Characterization of Thermophilic Bacilli Degrading Cinnamic, 4-Coumaric, and Ferulic Acids (2003)

Thirty-four thermophilic Bacillus sp. strains were isolated from decayed wood bark and a hot spring water sample based on their ability to degrade vanillic acid under thermophilic conditions. It was found that these bacteria were able to degrade a wide range of aromatic acids such as cinnamic, 4-coumaric, 3-phenylpropionic, 3-(p-hydroxyphenyl)propionic, ferulic, benzoic, and 4-hydroxybenzoic acids. The metabolic pathways for the degradation of these aromatic acids at 60 degrees C were examined by using one of the isolates, strain B1. Benzoic and 4-hydroxybenzoic acids were detected as breakdown products from cinnamic and 4-coumaric acids, respectively. The beta-oxidative mechanism was proposed to be responsible for these conversions. The degradation of benzoic and 4-hydroxybenzoic acids was determined to proceed through catechol and gentisic acid, respectively, for their ring fission. It is likely that a non-beta-oxidative mechanism is the case in the ferulic acid catabolism, which involved 4-hydroxy-3-methoxyphenyl-beta-hydroxypropionic acid, vanillin, and vanillic acid as the intermediates. Other strains examined, which are V0, D1, E1, G2, ZI3, and H4, were found to have the same pathways as those of strain B1, except that strains V0, D1, and H4 had the ability to transform 3-hydroxybenzoic acid to gentisic acid, which strain B1 could not do.
Antifertility Principle ofRuta graveolens (1989)

Chloroform extracts of the root, stem and leaf of Ruta graveolens L. showed significant anti-fertility activity in rats when administered intragastrically on days 1-10 post-coitum. Fractionation of the extracts led to the isolation of chalepensin as the active component with some toxicity. Time-dosing experiments demonstrated that chalepensin acts at the early stages of pregnancy. It is not clear at this stage if the anti-fertility effect is a direct manifestation of chalepensin toxicity.

Collagen Coating Promotes Biocompatibility of Semiconductor Nanoparticles in Stratified LBL Films (2003)

Nanostructured thin films fabricated from semiconductor nanoparticles (NPs) are of great interest for biomedical applications, but NP materials based on heavy metals can be cytotoxic. In this work, the preparation of semiconductor NPs followed the protocol of layer-by-layer (LBL) assembly, which alleviates this problem. Collagen/poly(acrylic acid) bilayers were added to CdTe/polycation LBL films to produce porous collagen bilayers. Such stratified multilayer systems showed successful cell attachment and survival while native NP films were strongly cytotoxic.
