The Mechanical Influence of Tissue Engineering Techniques on Tracheal Strength: An Experimental Study on Sheep Trachea (2002)

Tissue engineering is an attractive concept for facilitating the transplantation of different tissue types with a low immunogeneity and a well-preserved tissue structure. We examined the influence of treatment with trypsin/ethylenediamine tetraacetic acid (EDTA) on the mechanical properties of tracheae. Fresh sheep tracheae were stored in a trypsin/EDTA solution for various periods of time (24, 46, and 72 h) and their breaking strength was subsequently examined. The results were compared with native trachea. The treatment with trypsin/EDTA results in a considerable reduction of the mechanical stability under load, in this case compared with the tensile strength, that does not correlate with the results obtained from light-optical microscopy. The results from this study reveal that tissue preparation with trypsin/EDTA does not seem to be a suitable method of preparatory treatment of tracheae intended for transplantation.
Synthesis of nitroxide containing polyenes: Two chemically modified retinals and their interaction with bacterioopsin (1995)

Abstract The synthesis and spectroscopic characterization of two retinal analogues is described, the paramagnetic 3‐pyrrolin‐1‐yloxy analogue 1 and its diamagnetic equivalent, the 3‐pyrroline analogue 2. Various aspects of the synthesis of the aminoxy group containing polyenes are discussed. Upon interaction with bacterioopsin, both 1 and 2 are incorporated in the protein and form a system with λ max 459 nm. Neither of the two bacteriorhodopsin analogues is photoactive. ESR spectroscopy data of the system containing 1 show that the ring part of the chromophore in the protein is rigidly fixed in orientation.
Peach Cultivar Responses to Fruit Thinning with CPA1 (1970)

Abstract Chemical thinning of peaches was conducted under orchard conditions using CPA,3 followed by standard hand thinning, on the cultivars ‘Jerseyqueen,’ ‘Sunhigh,’ ‘Redhaven’, ‘Sunqueen’ and ‘Rio Oso Gem.‘ Timing of the 3 sprays at 150 ppm was based on the water volume displacement of 100 fruits selected at random from each plot: a) at 200 ml displacement, b) at 280 ml, and c) at 280 ml plus 4 days. The control was hand thinned only. Ovule length was measured at each spray timing and found to be 7–10 mm at the 280 ml water displacement; both ovule length and water displacement techniques were used to time CPA sprays in over 2000 acres of New Jersey orchards in 1968. Timing of the CPA thinner for optimum effectiveness in this experiment varied with cultivar. Individual fruit weight was greater on CPA-thinned trees than on the controls for the cultivars ‘Redhaven,’ ‘Rio Oso Gem,’ ‘Sunqueen’ and ‘Sunhigh’ at harvest. Chemically thinned ‘Jerseyqueen’ did not show an increased mean fruit weight at harvest. Yield reductions occurred on ‘Sunhigh’ at the 280 ml timing and on ‘Redhaven’ at the 280 ml + 4 days timing, due apparently to subsequent over-thinning by hand. Shading increased the thinning effectiveness of CPA on all cultivars. ‘Jerseyqueen’ and ‘Redhaven’ were difficult to thin with CPA under the conditions of this experiment. ‘Rio Oso Gem’ was moderately difficult, while ‘Sunhigh’ and ‘Sunqueen’ were thinned readily.
Towards energy efficient sensor nodes for online activity recognition (2017)

In sensor-based activity recognition often huge amounts of data have to be acquired from multiple sensors, which need to be communicated for further processing. When using wireless sensor nodes, energy efficiency is of outstanding importance, since it directly influences the time until the battery needs to be recharged. However, communicating a huge amount of sensor data over wireless interfaces causes high energy consumption as well. Furthermore, the host controller receiving the sensor data is hindered of using its low power modes, as it needs to be woken up more frequently as well. In the paper at hand, we introduce our approach of reducing energy consumption of sensor nodes in online activity recognition scenarios by calculating the feature extraction on the sensor subsystem itself. By doing so, we can reduce the output rate of the sensor which enables the host controller to stay in its low power modes for longer periods. Additionally, this approach drastically reduces the amount of data to be transmitted over wireless interfaces, which further improves energy consumption. In our experiments, the proposed approach reduces the energy consumption of a sensor node by up to 33 %.
Analysis of longer wavelength AlexaFluor dyes for use in a minimally invasive glucose sensor (2004)

A fluorescence based glucose biosensor, for diabetes management, was developed based on a fluorescent resonant energy transfer between fluorescein isothiocyanate and tetramethylrhodamine isothiocyanate. Upon implantation under the skin of a rat, large losses of fluorescent signal resulted in poor signal-to-noise and difficulty in correlating peak ratio to glucose concentration. In an attempt to remedy this issue the use of longer wavelength dyes was implemented in vitro. Experiments were performed to verify the effectiveness of the sensor using AlexaFluor 594 labeled dextran and AlexaFluor 647 labeled Concanavalin A while encapsulated in a poly( ethylene glycol) hydrogel sphere. Using porcine skin tissue, in vitro experiments were performed to quantify the improvement in signal-to-noise and peak resolution. The results indicated that the use of longer wavelength fluorophores allowed for better tissue penetration and in turn increased the overall signal-to-noise of the detection system.
Advanced Fuel Cell Development for Automotive Operation (2006)

<div class="htmlview paragraph">Proton exchange membrane (PEM) fuel cells are recognized as a good alternative to the internal combustion engine for automotive applications. During the past several years, many companies around the world have investigated this technology as potential solution in terms of efficiency improvements and emission targets for the future.</div> <div class="htmlview paragraph">However to be competitive with the internal combustion engine, the fuel cell must withstand the severe conditions imposed by the automotive environment while being economically affordable. At the current time, most original equipment manufacturers (OEM's) are targeting an allowable cost of about 30 $/kW in the 2010 timeframe.</div> <div class="htmlview paragraph">In order to help achieve this cost goal, one potential solution is to reduce the number of components in the fuel cell system. Along with reducing cost, the removal of components can lead to a reduction in system complexity and control.

Technological requirements for water system asset management (2006)

Asset management is a broad term and a relatively new paradigm to the water industry. This paper is intended to present an overview of the asset management approach that emerges as a managerial and technical framework for a water utility to effectively manage above and below ground assets. Based upon the lessons learned from some limited practices in the developed countries including UK, USA, Australia and New Zealand, the article is focused on elaborating the new concept of asset management and technological requirements to implement it for a water or wastewater organization. Following the brief overview, the elements of asset management are addressed along with the classified essential technology that enables water asset management and the potential cost savings resulting from an effective program. It concludes by looking into the challenges and barriers for adopting this innovative approach.
Evaluation of a Bypass System for Spent American Shad at Holyoke Dam, Massachusetts (1993)

A bypass system for postspawned American shad Alosa sapidissima began operation in 1980 on the Connecticut River canal system at Holyoke Dam. The purpose of the bypass was to enable downstream migrants that enter the canal to exit and avoid death due to delay or passage through hydroelectric turbines at water use facilities. The bypass system had the following elements: (1) an underwater AC electrical or acoustic barrier to prevent American shad from leaving the bypass area, (2) an underwater DC electrical field to immobilize fish for collection, and (3) a collection box with transfer pipe to carry fish to the river below the dam. During studies of the bypass system from 1979 to 1983, we found that the fish barriers were ineffective, the collection system was partially effective for American shad but not for anadromous species that passed through trashracks, and American shad could be immobilized and transported at high velocity through a pipe and have only low mortality (4–9%). Radio-tagged American shad, unwilling to pass through trashracks at water exits on the canal, behaved like trapped fish and were delayed an average of two or more days before dying or exiting the canal. An estimated 10 of 47 (21%) of the radio-tagged fish were passed. In 1980, when the greatest number of American shad were passed, an estimated 142,000 (37% ofthe fish lifted at the dam) survived spawning and used the bypass. After several years of operation, it was evident that, even with major improvements, the bypass could not pass the available American shad, and it was not useful for protecting other anadromous migrants that did not avoid trashracks.
A gain/phase calibration technique for adaptive beamforming (2002)

A calibration technique is proposed to handle the minimum variance distortionless response (MVDR) adaptive beamforming problems involving unknown perturbed sensor/channel gain and phase. This technique is using basically the property of the MUSIC null spectrum. From the computer study, it is found that this technique exhibits relatively stable performance over other existing techniques in the sense that it produces the required estimates accurately and consistently without the needs of iterative computation and initialisation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Spatially Resolved CO SLED of the Luminous Merger Remnant NGC 1614 with ALMA (2017)

Abstract We present high-resolution (1.″0) Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO (1–0) and CO (2–1) rotational transitions toward the nearby IR-luminous merger NGC 1614 supplemented with ALMA archival data of CO (3–2) and CO (6–5) transitions. The CO (6–5) emission arises from the starburst ring (central 590 pc in radius), while the lower- J CO lines are distributed over the outer disk (∼3.3 kpc in radius). Radiative transfer and photon-dominated region (PDR) modeling reveals that the starburst ring has a single warmer gas component with more a intense far-ultraviolet radiation field ( cm −3 , K, and ) relative to the outer disk ( cm −3 , K, and ). A two-phase molecular interstellar medium with a warm and cold (>70 and ∼19 K) component is also an applicable model for the starburst ring. A possible source for heating the warm gas component is mechanical heating due to stellar feedback rather than PDR. Furthermore, we find evidence for non-circular motions along the north–south optical bar in the lower- J CO images, suggesting a cold gas inflow. We suggest that star formation in the starburst ring is sustained by the bar-driven cold gas inflow and that starburst activities radiatively and mechanically power the CO excitation. The absence of a bright active galactic nucleus can be explained by a scenario where cold gas accumulating on the starburst ring is exhausted as the fuel for star formation or is launched as an outflow before being able to feed to the nucleus.

Diphtheria Toxin-Mediated Cell Ablation Reveals Interregional Communication during Arabidopsis Seed Development (2003)

Fertilization of the female gametophyte in angiosperm plants initiates a process of coordinated development of embryo, endosperm, and seed coat that ensures the production of a viable seed. Mutant analysis has suggested that communication between the endosperm and the seed coat is an important determinant in this process. In addition, cell groups within the embryo, derived from the apical and from the basal cell, respectively, after zygote division, concertedly establish a functional root meristem, and cells in the apical region of the embryo are hypothesized to repress cell divisions in the basal cell-derived suspensor. The available evidence for these interregional communication events mostly relies on the analysis of mutant phenotypes in Arabidopsis. To provide independent and direct evidence for communication events, we used conditional domain-specific expression of the diphtheria toxin A chain (DTA) in developing Arabidopsis seeds. By using a collection of cell- or tissue-type-specific promoters, we show that the mGAL4:VP16/UAS two-component gene expression allows reliable spatiotemporal and conditional expression of the GFP:GUS reporter and the DTA gene in the developing embryo and endosperm. Expression of DTA in the protoderm of the embryo proper led to excessive proliferation of suspensor cells, sometimes resulting in the formation of secondary embryos. Endosperm-specific expression of DTA caused complete cessation of seed growth, followed by pattern defects in the embryo and embryo arrest. Taken together, the results presented here substantiate the evidence for and underline the importance of interregional communication in embryo and seed development and demonstrate the usefulness of conditional toxin expression as a method complementary to phenotypic analysis of developmental mutants.
Far-field emission pattern and photonic band structure in one-dimensional photonic crystals made from semiconductor microcavities (1999)

One-dimensional (1D) photonic crystals have been investigated by angle-resolved photoluminescence measurements. The crystals have been fabricated out of a semiconductor microcavity by lateral etching of photonic wires with a 1D lattice of small holes in the top mirror stack along the wire axis. The photonic band structure of such photonic crystals has been shown to demonstrate very small photonic gaps and can be regarded as a set of modes with the dispersion curves being replicas of the photonic wire modes periodically shifted with an integer number of the Brillouin zone periods. The replicas are well observed only for the even photonic wire modes which have the antinodes at the hole locations. The far-field emission pattern of the replicas demonstrates a much wider angle distribution than that of the main modes having the energy minima at $k=0.$
Characterization by radiosequencing of the carboxyl-terminal derivatives produced from normal and mutant amyloid β protein precursors (1994)

The 39–43 amino acid (∼ kD) amyloid β protein (Aβ) deposited as amyloid Alzheimer's disease is an internal peptide beginning 99 residues from the COOH end of a much larger amyloid fiprotein precursor (βAPP). In cultured cells, normal processing of the PAPP produces ∼8.7, ∼9.6, ∼10.9, and ∼ 11.4 kD COOH-terminal derivatives that appear to contain all or part of the Aβ domain. In this study, we metabolically labeled transfected human neuroblastoma (Ml 7) cells with PH] phenylalanine plus (35SJmethionine and then radiosequenced the immunopre-cipitated COOH-terminal βAPP derivatives taking advantage of the fact that the Aβ has phenylalanines at positions 4, 19, and 20, and a single methionine at position 35. Our analysis of the derivatives produced by transfected Ml 7 cells expressing βAPP695 confirms that the ∼8.7 kD COOH-terminal derivative begins at Aβ17 and indicates that the ∼9.6 and ∼10.9 kD derivatives begin at Aβ10 and Aβ4 respectively. Significantly, we find that the 11.4 kD derivative begins at APr Thus normal PAPP processing produces a potentially amyloidogenic COOH-terminal derivative that has the Aβ domain intact at its amino terminus. We have previously shown that cells expressing βAPPWL, a mutant linked to familial Alzheimer's disease, produce an increased amount of the 11.4 kD COOH-terminal derivative and secrete more Aβ. Radiosequencing of these derivatives showed that the ANL mutant is cleaved at the same location as wild type βAPP producing an 11.4 kD COOH-terminal derivative and Aβ that both begin at Aβ Thus the ANL mutation appears to accelerate a cleavage that releases an 11.4 kD COOH-terminal derivative identical to that normally produced from wild type PAPP, and it appears that this 11.4 kD derivative is further processed to release excess Aβ.

Prolonged Survival of Rat Renal Allografts after Multiple Allogeneic Pregnancies: Strain Specificity and role of Erythrocyte Antibody Rosette Inhibiting Antibodies (1985)

The influence of allogeneic pregnancies on the survival of subsequent rat renal allografts was investigated in three rat strain combinations. Multiple but not single pregnancies produced significantly more long-term surviving kidney grafts than were found in virgin animals; the effect was specific for paternal antigens, as multiple pregnancies by an unrelated strain did not prolong kidney graft survival. In the multiparous groups, those animals with long-surviving grafts had significantly higher levels of non-cytotoxic antibodies against paternal strain B-lymphocytes (detected by the erythrocyte antibody rosette inhibition assay) than did animals which rejected their grafts. The results show that multiple pregnancies may produce a state of specific unresponsiveness to paternal antigens, similar to enhancement, which is marked by the presence of non-cytotoxic antibodies against paternal B-lymphocytes. It is suggested, therefore, that enhancement may be one of the protective mechanisms which prevent rejection of the fetus during pregnancy.
Facial pain due to vascular lesions of the brain stem relieved by dorsal root entry zone lesions in the nucleus caudalis (1992)

One patient with a pontine infarct due to a fusiform basilar artery aneurysm and one with an arteriovenous malformation within the tectum of the mesencephalon developed intractable facial pain. This pain was relieved in both patients by radiofrequency lesions in the dorsal root entry zone of the trigeminal nucleus caudalis.
The Mechanism for Hydrogen Abstraction by n,π* Excited Singlet States: Evidence for Thermal Activation and Deactivation through a Conical Intersection (1998)

A conical intersection along the reaction coordinate of hydrogen abstraction by molecules in n,π* excited singlet states is responsible for the solvent-induced fluorescence quenching of azoalkanes [see equation]. This novel photochemical reaction mechanism, a case of aborted hydrogen abstraction, was examined by experiment and theory. Mutually consistent results on the observed low activation energies and the deuterium isotope effects were obtained.
Nanotube Micro-Opto-Mechanical Systems (N-MOMS) (2007)

In this paper we report the first applications of single wall carbon nanotube based micro-optomechanical systems (MOMS). Thin films of nanotubes with line widths ranging less than 1.5 μm and thicknesses ranging from 40 to 700 nm were patterned into micro-mechanical systems using batch fabrication techniques. Arrays of nanotube based MOM actuators, MOM-micromirrors and MOM-micro-grippers were fabricated using CMOS compatible techniques. Nanotube based MOMS devices showed better performance compared to their MEMS based electrostatic silicon counterparts and consumed only 200 μW-170 mW of power. These studies open a new field of nanotube based MOMS that could potentially outperform silicon based MEMS devices.
