Analysis of Bloch’s Method in Structures with Energy Dissipation (2011)

Bloch analysis was originally developed to solve Schrödinger’s equation for the electron wave function in a periodic potential field, such as found in a pristine crystalline solid. In the context of Schrödinger’s equation, damping is absent and energy is conserved. More recently, Bloch analysis has found application in periodic macroscale materials, such as photonic and phononic crystals. In the vibration analysis of phononic crystals, structural damping is present together with energy dissipation. As a result, application of Bloch analysis is not straightforward and requires additional considerations in order to obtain valid results. It is the intent of this paper to propose a general framework for applying Bloch analysis in such systems. Results are presented in which the approach is applied to example phononic crystals. These results reveal the manner in which damping affects dispersion and the presence of band gaps in periodic systems.
TeleTruck : a holonic fleet management system (1997)

In this paper we describe TeleTruck, a multiagent dispatching system that was developed in close cooperation with a forwarding company and that is capable of handling real-world requirements like dynamics and uncertainty. The main idea underlying the TeleTruck approach is the usage of holonic agents, i.e. agents composed of subagents that act in a corporated way. We describe the implementation in detail and point out the advantages of the holonic paradigm.

Formulation and Design of Veterinary Tablets (2013)

Veterinary pharmaceuticals have an important role in the preservation and restoration ofanimal health. For companion animal species such as dogs and cats, medicinal productsare needed to treat a range of disease conditions, many of which parallel those associatedwith human patients. For example, in dogs, drugs are used to treat infections diseases,parasitic infections, metabolic disorders, epilepsy, post-surgical pain, pain associatedwith osteoarthritis, heart disease, anxiety, obesity, and cancer. For poultry, livestock andaquatic species, therapeutic needs include the treatment of bacterial and parasiticinfections, the management of metabolic disorders, productivity enhancers (e.g.,enhancing growth, reproduction, feed efficiency and milk production), and control ofpain and pyrexia.
Total Arterial Myocardial Revascularization Using New Composite Graft Techniques for Internal Mammary and/or Radial Arteries Conduits (2010)

These data indicate that TAMR in young patients perhaps offers a better postoperative outcome and perhaps should be part of the surgical armamentarium. These techniques apply the "nontouch" principle and should be taken into consideration in patients with a heavily calcified aorta. Contrast-enhanced TTE color Doppler is a safe, accurate, and noninvasive test, which allows assessment of IMA patency and CFR evaluation. The flow reserve of the IMAs seems to be adequate for multiple coronary anastomoses.
Elastic-Plastic Analysis of an Infinite Sheet Having a Circular Hole Under Pressure (1975)

An exact elastic-plastic solution for the stresses in an infinite sheet having a circular hole subject to pressure is obtained on the basis of J2 deformation theory together with a modified Ramberg-Osgood law. The sheet is orthotropic but isotropic in its plane. The results are assessed on the basis of Budiansky’s criterion for the acceptability of J2 deformation theory. By using exact elastic-plastic stresses, the function connecting the pressure at the hole with the radial enlargement is obtained. Upon release of the pressure, residual stresses around the hole are produced.
Development of a Semi-Implicit Solver for Detailed Chemistry in I.C. Engine Simulations (2005)

An efficient semi-implicit numerical method is developed for solving the detailed chemical kinetic source terms in I.C. engine simulations. The detailed chemistry system is a group of coupled extremely stiff O.D.E.s, which presents a very stringent timestep limitation when solved by standard explicit methods, and is computationally expensive when solved by iterative implicit methods. The present numerical solver uses a stiffly-stable noniterative semi-implicit method, in which the numerical solution to the stiff O.D.E.s never blows up for arbitrary large timestep. The formulation of numerical integration exploits the physical requirement that the species density and specific internal energy in the computational cells must be nonnegative, so that the Lipschitz timestep constraint is not present [1,2], and the computation timestep can be orders of magnitude larger than that possible in standard explicit methods and can be formulated to be of high formal order of accuracy. The solver exploits the characteristics of the stiffness of the O.D.E.s by using a sequential sort algorithm that ranks an approximation to the dominant eigenvalues of the system to achieve maximum accuracy. Subcycling within the chemistry solver routine is applied for each computational cell in engine simulations, where the subcycle timestep is dynamically determined by monitoring the rate of change of concentration of key species which have short characteristic time scales and are also important to the chemical heat release. The chemistry solver is applied in the KIVA-3V code to diesel engine simulations. Results are compared with those using the CHEMKIN package which uses the VODE implicit solver. Very good agreement was achieved for a wide range of engine operating conditions, and 40∼70% CPU time savings were achieved by the present solver compared to CHEMKIN.
The Role of Valence on the High-Affinity Binding ofGriffonia simplicifoliaIsolectins to Type A Human Erythrocytes (1998)

The Griffonia simplicifolia-I (GS-I) isolectins have been used to probe the effect of lectin valence on their high-affinity binding to human erythrocytes. These tetrameric lectins are composed of A and B subunits and constitute a series of five isolectins (A4, A3B, A2B2, AB3, B4). The A subunit is specific for alpha-D-GalNAc end groups and binds to the blood type A determinant GalNAcalpha1, as well as to terminal alpha-D-Gal groups found on type B cells. The B subunit is specific for alpha-D-Gal end groups, and binds very specifically to type B erythrocytes. This series of isolectins is tetravalent (A4), trivalent (A3B), divalent (A2B2), and monovalent (AB3) for type A erythrocytes; thus, this system provides the opportunity to examine the effect of lectin valency on the association constants of these GS-I isolectins binding to cells. Cell binding experiments carried out using 125I-labeled GS-I isolectins and type A human erythrocytes allowed us to demonstrate that (1) the association constant of the isolectin monovalent for alpha-D-GalNAc (AB3) is virtually identical to its association constant for the haptenic sugar methyl-N-acetyl-alpha-D-galactosaminide, reported previously, and (2) the association constant of the GS-I isolectins for human type A erythrocytes increases with increasing valency of the isolectin. These results indicate that the increased affinity displayed by the GS-I isolectins for human type A erythrocytes is dependent on their multivalency, and not on an extended binding site nor on nonspecific, or noncarbohydrate, interactions of the lectin with the cell surface. These findings should be of general relevance to understanding the high-affinity interactions observed between other multivalent proteins and multivalent ligands (e.g., cell surfaces).
A Scalable RDMA Network Interface Card with Efficient Cache Management (2023)

Remote Direct Memory Access (RDMA) has been applied in large-scale clusters due to its high bandwidth and low latency features in recent decades. However, the scalability issue is a known intractable problem that the current RDMA Network Interface Card (RNIC) cannot overcome as the number of connections increases to thousands. The key to the scalability bottleneck is managing the connection information cached on the RNIC. To solve the scalability problem, firstly, we test and analyze the behavior of the commercial RNIC when the network performance declines in the case of large-scale connections. Further, we give the performance model of RNIC and point out that the cache design is the key to scalability issues. Then, we propose a Scalable RDMA NIC (ScalaRNIC) architecture with a non-blocking and priority-programmable cache design. Besides, our cache design supports parametric configuration by the extended API. ScalaRNIC can maintain <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathrm{a}\approx 100\%$</tex> cache hit ratio for higher priority connections and keep message rates nearly equal to peak performance. In contrast, commercial RNIC's performance drops by 47% when there are a few thousand connections.
Diffusion of Ions in Some Simple Glasses (1951)

An investigation of the diffusion of ions in several glasses was made using radioactive tracer techniques. The resulting diffusion curves were analyzed to obtain the thermodynamic properties of the diffusion process. These properties are indicative of energy and structure changes in the glass networks. Interpretations of the results are advanced.
Fabrication and characterization of high-contrast mid-infrared GeTe_4 channel waveguides (2015)

We report the fabrication and characterization of high index contrast (Δn≈0.9) GeTe4 channel waveguides on ZnSe substrate for evanescent-field-based biosensing applications in the mid-IR spectral region. GeTe4 films were deposited by RF sputtering and characterized for their structure, composition, transparency, and dispersion. The lift-off technique was used to pattern the waveguide channels. Waveguiding from 2.5-3.7 and 6.4-7.5 μm was demonstrated, and mode intensity profile and estimated propagation losses are given for the 3.5 μm wavelength.
Methyl jasmonate-induced emission of biogenic volatiles is biphasic in cucumber: a high-resolution analysis of dose dependence (2017)

Methyl jasmonate (MeJA) is a key airborne elicitor activating jasmonate-dependent signaling pathways, including induction of stress-related volatile emissions, but how the magnitude and timing of these emissions scale with MeJA dose is not known. Treatments with exogenous MeJA concentrations ranging from mild (0.2 mM) to lethal (50 mM) were used to investigate quantitative relationships among MeJA dose and the kinetics and magnitude of volatile release in Cucumis sativus by combining high-resolution measurements with a proton-transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS) and GC-MS. The results highlighted biphasic kinetics of elicitation of volatiles. The early phase, peaking in 0.1-1 h after the MeJA treatment, was characterized by emissions of lipoxygenase (LOX) pathway volatiles and methanol. In the subsequent phase, starting in 6-12 h and reaching a maximum in 15-25 h after the treatment, secondary emissions of LOX compounds as well as emissions of monoterpenes and sesquiterpenes were elicited. For both phases, the maximum emission rates and total integrated emissions increased with applied MeJA concentration. Furthermore, the rates of induction and decay, and the duration of emission bursts were positively, and the timing of emission maxima were negatively associated with MeJA dose for LOX compounds and terpenoids, except for the duration of the first LOX burst. These results demonstrate major effects of MeJA dose on the kinetics and magnitude of volatile response, underscoring the importance of biotic stress severity in deciphering the downstream events of biological impacts.
Multiphase concentration field measured by Compton scattering of internal gamma emitters using stationary instrumentation (1990)

Besides two-phase fluids, a number of other multiphase/multicomponent systems (including solids) requires nonintrusive and nondestructive testing, often as part of in-service inspection, preferably done with stationary instrumentation. Safety of high-pressure boiling systems, chemical process control, integrity of structural components under stress (especially in view of aging effects), have one thing in common: All of them are affected by voids (cavities), inclusions, and other discontinuities. Their pressure, size, quantity, and spatial distribution are important characteristics of the systems mentioned. Thus, in essence, the examiner's goal is to determine the mass concentration field within the system (object) of interest. During the past two decades, Compton-type gamma scattering, occurring in passive measured systems (with sources and detectors external to the interrogated, radiation attenuating and scattering system) has proven successful in measuring density fields. The new proposed measurement procedure is an active one, with inverted roles of sources and scatters; the sources are continuous and internal, within the mass of the measured system, making it radioactive. The scatterers are external; they are small bodies, optimally designed and placed to view the sources and send once-scattered gammas to one or several detectors. The latter ones are external and discrete entities in both active and passivemore » systems. Both scattering approaches use existing and already developed instrumentation and equipment.« less
The potential of early human embryos to form blastocysts, hatch from their zona and secrete HCG in culture (1989)

Early embryos assessed to be unsuitable for transfer to patients or for cryopreservation were cultured either in minimum essential medium (MEM) or in synthetic human tubal fluid (HFT). A significantly higher percentage of embryos developed to blastocysts in MEM (26.5%) than in HTF (14.5%). Serum was not required for blastocyst formation nor for hatching in MEM. HTF containing 1% human cord serum failed to support blastocyst hatching. Haploid (monopronucleate) and diploid (bipronucleate) embryos formed blastocysts and hatched with a similar frequency but triploid (tripronucleate) embryos developed poorly. Human chorionic gonadotrophin (HCG) released by hatched and intrazonal blastocysts was detected between days 7 and 8 after fertilization. The mean total HCG produced by hatched blastocysts by day 14 was 19,500 mIU, but embryos trapped inside their zonae released a mean level of 1550 mIU. Serum was shown to stimulate the output of HCG from both hatched and intrazonal blastocyst tissues. Free beta- and alpha-subunits of HCG were not released by developing blastocysts, but low levels of beta-HCG were produced by some embryonic tissues between days 12 and 14 when degenerative changes were observed.
UMASST: A New Teaching Tool for Stress State Transformation (2003)

This paper presents UMASST, the UMASS Stress State Transformation tutor. UMASST is a multimedia tutor based on active engagement of the learner and the use of visualization. The development of UMASST was informed by cognitive models of human reasoning, research on how people learn and computing technology. As a multimedia Director® and web-based application with knowledge-centered and assessment-centered modules, the UMASST targets improving understanding and mastery of transformation of stress states in mechanics of materials. In the knowledge-centered modules learners receive in-depth information on physical meaning and real-life applications of stress state transformations before their understanding is assessed in interactive workshops. The assessment-centered modules assist novices in assessing themselves on the subject domain. Assessment results show that the current efficacy of the UMASST tutor is above that of in-class lectures. Future work will include a learner-centered module customizing learning process by considering learners’ individual backgrounds.
Fundamental Concepts of Analytical Electrochemistry (2018)

The common thread binding all electroanalytical methods is heterogeneity. The very act of placing an electrode in contact with a solution creates a phase boundary that differentiates otherwise identical solute molecules into two types: those at a distance from the electrode, and those close enough to participate in the fascinating mutual interactions known collectively as electrochemistry. This is not a trivial distinction, for often it is the bulk-phase properties alone that are of analytical concern. Unlike most spectroscopic methods, electrochemical measurements are actually made on only a minute fraction of the sample confined to a highly nonhomogeneous environment, the electrode-solution interphase. The coupling and interplay within this region of such phenomena as interfacial charge transfer, diffusional mass transport, adsorption, chemisorption, homogeneous-phase chemical reaction, convection, and dissolution can cloud the interpretation of electrochemical data and discourage the practically minded analyst. On the other hand, electrochemistry offers an invaluable tool for fundamental investigation of these processes, each important in its own right. In either case, the ultimate success of the experimenter will depend on a firm grasp of the underlying physical principles.
