A Privilege Management Scheme for Mobile Agent Systems (2002)

In this paper, we describe a general method for controlling the behavior of mobile agent-system entities through the allocation of privileges. Privileges refer to policy rules that govern the access and use of computational resources and services. The scheme is based on the capability of most mobile agent systems to extend the platform processing environment and the use of two forms of privilege management certificates: attribute certificates and policy certificates. Privilege management certificates are digitally signed objects that allow various policy-setting principals to govern the activities of mobile agents through selective privilege assignment. This approach overcomes a number of problems in existing agent systems and provides a means for attaining improved interoperability of agent systems designed and implemented independently by different manufacturers. We also describe applying the scheme to Java-based agent systems.
Evidence for the enzymic degradation of TRH‐related pseudo‐peptides by porcine serum and brain homogenate (1981)

Pseudo-peptides (pGlu-His-amphetamine, pGlu-His-pro-Amphetamine and pGlu-amphetamine) were subjected to enzymatic degradation by porcine serum and brain homogenate. The enzymic digests were (qualitatively) analyzed by the "Finger-prints" technique to provide evidence for the presence of free pyroglutamic acid and also quantitatively by HPLC to provide evidence for the presence and yield of free amphetamine. The stability in vitro toward enzymes of serum and brain homogenate of a new type of drug based on the combination of a peptide moiety (TRH) with a non peptide psycho-tropic moiety (amphetamine) is also considered and discussed.
Anisotropic nonmonotonic behavior of the superconducting critical current in thinYBa2Cu3O7−δfilms on vicinalSrTiO3surfaces (2005)

The critical current density of epitaxial $\mathrm{Y}{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ (YBCO) films grown on vicinal $\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$ substrates was investigated by electrical transport measurements along and across the steps of the $\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$ surface for a range of temperatures of $10\phantom{\rule{0.3em}{0ex}}\text{to}\phantom{\rule{0.3em}{0ex}}85\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ and in applied magnetic fields varying from $0\phantom{\rule{0.3em}{0ex}}\text{to}\phantom{\rule{0.3em}{0ex}}14\phantom{\rule{0.3em}{0ex}}\mathrm{T}$. For vicinal angles of 4\ifmmode^\circ\else\textdegree\fi{} and 8\ifmmode^\circ\else\textdegree\fi{}, we found evidence of enhanced pinning in the longitudinal direction at low magnetic fields for a wide region of temperatures and attribute this phenomenon to antiphase boundaries in the YBCO film. The transverse ${J}_{c}$ data showed a peak in the ${J}_{c}(\mathrm{H})$ curve at low magnetic fields, which was explained on the basis of magnetic interaction between Abrikosov and Abrikosov-Josephson vortices. The in-plane ${J}_{c}$ anisotropy observed for vicinal angles of 0.4\ifmmode^\circ\else\textdegree\fi{} was reversed with respect to the 8\ifmmode^\circ\else\textdegree\fi{} and 4\ifmmode^\circ\else\textdegree\fi{} samples. This phenomenon was interpreted on the basis of strain induced in the YBCO film by the stepped substrate's surface.
Fast Implementations of AES Candidates. (2000)

Of the five AES finalists four---MARS, RC6, Rijndael, Twofish---have not only (expected) good security but also exceptional performance on the PC platforms, especially on those featuring the Pentium Pro, the NIST AES analysis platform. In the current paper we present new performance numbers of the mentioned four ciphers resulting from our carefully optimized assembly-language implementations on the Pentium~II, the successor of the Pentium Pro. All our implementations follow well-defined API and timing conventions and sensible guidelines, like no using of self-modifying code and key-specific static data --- i.e., tricks that speed up the implementation but at the same time restrict the field of application. Our implementations are up to 26% percent faster than previous implementations. Our work also shows how a simple change (inclusion of the MMX technology) in the analysis platform can influence the relative encryption speed of different ciphers. To enable everyone to compare their implementations to ours, we also fully specify our procedures used to obtain the speed numbers.

A Bioartificial Ventricle Used as a Totally Implantable Circulatory Assist Device (1992)

The authors designed a totally implantable circulatory assist device consisting of a bioartificial ventricle composed of a skeletal muscle ventricle lined with a bioartificial endocardium. The bioartificial endocardium consists of a structural matrix made of a polyurethane porous membrane, fragmented blood vessels, and collagen gel. The authors prepared the polyurethane porous membrane by solvent cocasting with salt powder. They used collagen gel with fragmented goat carotid vein to perform in vitro construction of the bioartificial endocardium. For in vivo construction of the bioartificial endocardium, the authors used a modified version of the tissue fragment method for vascular prostheses. The authors prepared suspensions of tissue fragments using collagen gel with fragmented goat carotid artery. They used a highly porous fabric vascular prosthesis as a structural matrix; tissue fragments were entrapped on the outer surface of the prosthesis, and the prosthesis then was implanted into the carotid artery of four adult goats. In specimens 1 and 3 months postimplantation, cells from the fragmented tissue regenerated an endothelium-like monolayer sheet on the inner surface of the prostheses. Output of a prototype bioartificial ventricle reached 660 ml/min at an afterload of 60 mmHg and a preload of 20 mmHg. Based on these data, the authors conclude that the bioartificial ventricle is promising as an implantable device with excellent antithrombogenicity.
Flow-controlled synthesis of gold nanoparticles in a biphasic system with inline liquid–liquid separation (2020)

Dynamics of cytokine production during coccidial infections in chickens: colony-stimulating factors and interferon (1993)

We assayed two classes of immunoregulatory cytokines, colony-stimulating factors (CSF) and interferon (IFN), during and immediately after a primary coccidial infection in chickens. Coccidial infection induces significant alterations in serum colony-stimulating activity (CSA) and these alterations immediately precede the characteristic biphasic leukocytosis. CSA rose sharply during the first 24 h post-inoculation (PI), but returned to control levels by 48 h PI. At this time, we detected an increase in peripheral blood leukocytes which peaked at 96 h PI. A second phase of CSA increase began 96 h PI and peaked at 120-144 h PI which again preceded the second phase of leukocytosis. We also examined the production of IFN during the first 20 days PI. Splenic T cells from Eimeria maxima-infected chickens produced significantly less IFN on day 5 PI compared to T cells from the coccidia-free controls. By days 10 and 15 PI, there was no significant difference in IFN production between the T cells of infected and non-infected chickens. However, by day 20 PI, IFN production by the T cells of the infected birds produced significantly more IFN than the control T cells. The results of our studies indicated the differential production of two different cytokines by chickens during and following a primary coccidial infection. Based on these experiments, CSF may be some of the first cytokines produced during an E. maxima-infection, while IFN may be one of the later cytokines produced.
Novel concept for full‐color electronic paper (2009)

Abstract— Despite a steep increase in commercial devices comprising paper‐like displays, a much desired feature is still missing: bright full‐color electronic paper. A new reflective‐display technology has been developed to solve this issue. For the first time, the principles behind this in‐plane electrophoretic technology will be presented, which enables the realization of full‐color reflective displays with a higher brightness than presently available e‐paper technologies, without compromising paper‐like properties such as viewing angle and ultra‐low power consumption. An additional major advantage ( e.g. , for future low‐cost manufacturing) is that, besides direct‐drive and active‐matrix configurations, a passive‐matrix option with analog gray levels has been successfully developed.
Wireless power meets energy harvesting: A joint energy allocation approach (2014)

This paper investigates power allocation design for a wireless powered communication system, where one user harvests radio frequency (RF) energy from an energy access point (EAP) that can be used immediately to power its information transmission to a data access point (DAP). The channels from the EAP to the user and from the user to the DAP are assumed to be time-varying over two separate bands but a priori known. Our objective is to maximize the achievable rate at the DAP by jointly optimizing the power allocation at both links, subject to the sum power constraint at the EAP and the energy causality constraint at the user. We study the structural properties of the optimal power allocation, based on which we propose an efficient algorithm to solve the problem. It is shown that by optimizing energy transmission at the EAP, higher rate can be achieved than a conventional energy harvesting system where the user randomly harvests energy from the environment with the same sum power.
The earthquake history in a fault zone tells us almost nothing about mmax (2016)

In the present study, we summarize and evaluate the endeavors from recent years to estimate the maximum possible earthquake magnitude mmax from observed data. In particular, we use basic and physically motivated assumptions to identify best cases and worst cases in terms of lowest and highest degree of uncertainty of mmax. In a general framework, we demonstrate that earthquake data and earthquake proxy data recorded in a fault zone provide almost no information about mmax unless reliable and homogeneous data of a long time interval, including several earthquakes with magnitude close to mmax, are available. Even if detailed earthquake information from some centuries including historic and paleoearthquakes are given, only very few, namely the largest events, will contribute at all to the estimation of mmax, and this results in unacceptably high uncertainties. As a consequence, estimators of mmax in a fault zone, which are based solely on earthquake‐related information from this region, have to be dismissed.

Immunohistochemical and electron microscopic studies on intracranial chordomas: difference between typical chordomas and chondroid chordomas. (1994)

Immunohistochemical and electron microscopic studies were carried out on 9 cases of intracranial chordomas. Three of them were typical chordomas and 6 were chondroid chordomas. Immunohistochemically, both typical chordomas and chondroid chordomas were positively stained for cytokeratin and epithelial membrane antigen. Chondroid chordomas were stained for vimentin with moderate intensity whereas typical chordomas were only slightly stained. In comparison to typical chordomas, the chondroid chordomas had relatively few desmosomes and intermediate filaments. These findings suggest that intracranial chordomas are of mixed epithelial-mesenchymal nature, and that chondroid chordomas have a predominant mesenchymal character as compared to typical chordomas.
Diseases of Corn (1988)

Corn is affected by both biotic and abiotic agents. This chapter addresses both types of causal agents. It is the responsibility of the plant pathologist to assist in attempts to minimize crop losses caused by disease. Because of its stature as a food and feed crop, its genetics, and its adaptability to most environments, corn and its diseases can serve as a model system by which certain principles of plant disease development and disease control can be understood and practiced to accomplish the pathologist's responsibility. Abiotic diseases of corn are caused by noninfectious entities. Two main types of abiotic diseases affect corn. One type of disease is the result of internal genetic factors within the plant. The other is a result of external stimuli being exerted upon the corn plant. This type of disease can be further grouped into climatically induced diseases, management practice-induced diseases, and diseases caused by air pollutants.
Impact of body bias on delay fault testing of nanoscale CMOS circuits (2005)

A body biasing technique has recently been proposed for microprocessors in sub-100 nm technology generations. It is shown that forward body bias (FBB) reduces the leakage power and suppresses the effect of process variation while reducing the complexity of dual V/sub th/ technology. We study the effect of body bias on the delay fault testing of CMOS circuits. We analyze the impact of both fixed and adaptive body biasing techniques on test cost and the quality of test. Statistical analysis on several benchmark circuits shows that the adaptive body biasing design have the most effective impact on delay fault by maintaining the test cost at its minimum under process variation while ensuring the test quality at its highest level.
[Study on the seropositive prevalence of human immunodeficiency virus in a village residents living in rural region of central China]. (2004)

Some villages in the rural regions of central China showed high HIV prevalence. Former paid blood donation was responsible for the main transmission route in these villages. However, sexual transmission and mother-to-child transmission were becoming dominant routes in general population which called for effective action be taken to contain the spread of HIV.
Ceramic Hollow Fibre Constructs for Continuous Perfusion and Cell Harvest from 3D Hematopoietic Organoids (2018)

Tissue vasculature efficiently distributes nutrients, removes metabolites, and possesses selective cellular permeability for tissue growth and function. Engineered tissue models have been limited by small volumes, low cell densities, and invasive cell extraction due to ineffective nutrient diffusion and cell-biomaterial attachment. Herein, we describe the fabrication and testing of ceramic hollow fibre membranes (HFs) able to separate red blood cells (RBCs) and mononuclear cells (MNCs) and be incorporated into 3D tissue models to improve nutrient and metabolite exchange. These HFs filtered RBCs from human umbilical cord blood (CB) suspensions of 20% RBCs to produce 90% RBC filtrate suspensions. When incorporated within 5 mL of 3D collagen-coated polyurethane porous scaffold, medium-perfused HFs maintained nontoxic glucose, lactate, pH levels, and higher cell densities over 21 days of culture in comparison to nonperfused 0.125 mL scaffolds. This hollow fibre bioreactor (HFBR) required a smaller per-cell medium requirement and operated at cell densities > 10-fold higher than current 2D methods whilst allowing for continuous cell harvest through HFs. Herein, we propose HFs to improve 3D cell culture nutrient and metabolite diffusion, increase culture volume and cell density, and continuously harvest products for translational cell therapy biomanufacturing protocols.
Real-Time Temperature and Heat Flux Measurements for Lyophilization Process Design and Monitoring: Part 2 (2016)

Lyophilization is a sublimation drying process that is often used in the pharmaceutical and food industry to make products more stable and increase shelf life [1]. The lyophilization process is very temperature and pressure sensitive so close monitoring is required to ensure the final product quality. New wireless temperature sensors are designed to monitor the product’s temperature in situ effectively to ensure cake stability. The sensors were tested in Wheaton 6R vials simultaneously with the wired thermocouples using solutions of 5% w/v sucrose in ultra-pure water. The data collected from each of the experiments were used to model the heat flux through the vials. We intend to compare the experimentally determined data with results produced by the numerical model, in order to gauge the accuracy of the numerical model. We also aim to evaluate whether the wireless temperature sensors can accurately and reliably monitor the product temperature and develop approaches for sensor applications in lyophilization process research.
Data Center Demand Response Pricing Using Inverse Optimization (2019)

In Demand Response (DR), consumers regulate their power based on requests from an energy supplier. Data Centers (DC) are among the promising candidates to perform DR to help stabilize the power grid due to their flexibility and controllability. In this work, we present a novel framework for offering incentives to DCs so they can dynamically adjust their electricity consumption and provide DR to the grid. Coordination between an Independent System Operator (ISO) and DCs is done through pricing where the ISO computes optimal prices which elicit desired responses from the DCs. We model DCs using realistic cost functions based on Quality of Service (QoS) requirements of the DC workloads and present an inverse optimization approach to cost function parameter estimation for precise and efficient pricing along with simulation results that highlight the strength of our approach.
Effect of pulmonary lymphatic obstruction on respiratory rate and airway rapidly adapting receptor activity in rabbits. (1994)

1. The effects on respiratory rate of obstruction of pulmonary lymph flow, reduction of plasma protein concentration and a combination of the two procedures were examined in anaesthetized rabbits. The former was achieved by raising the pressure in a pouch created from the right external jugular vein and the latter by batch plasmapheresis. 2. In spontaneously breathing rabbits, neither pulmonary lymphatic obstruction (n = 6) nor plasmapheresis (n = 5) produced a significant change in respiratory rate. However, their combination (n = 8) produced a significant increase in respiratory rate (P < 0.05). 3. Cooling of the cervical vagi to 8-9 degrees C (n = 4) and vagotomy (n = 7) abolished this response. 4. There was a significant increase in the activity of the airway rapidly adapting receptors (RARs; n = 9) during pulmonary lymphatic obstruction, plasmapheresis and their combination (P < 0.05). 5. It is concluded that in the rabbit, obstruction of lymphatic drainage from the lung after plasmapheresis causes a reflex increase in respiratory rate. The afferent pathway for this reflex response lies in the vagus nerve and the RARs are likely to be the receptors involved in this response.
Polarization of Myosin II refines tissue material properties to buffer mechanical stress (2017)

Summary As tissues develop, they are subjected to a variety of mechanical forces. Some of these forces, such as those required for morphogenetic movements, are instrumental to the development and sculpting of tissues. However, mechanical forces can also lead to accumulation of substantial tensile stress, which if maintained, can result in tissue damage and impair tissue function. Despite our extensive understanding of force-guided morphogenesis, we have only a limited understanding of how tissues prevent further morphogenesis, once shape is determined after development. Buffering forces to prevent cellular changes in response to fluctuations of mechanical stress is critical during the lifetime of an adult organism. Here, through the development of a novel tissue-stretching device, we uncover a mechanosensitive pathway that regulates tissue responses to mechanical stress through the polarization of Myosin II across the tissue. Mechanistically, this process is independent of conserved Rho-kinase signaling but is mediated by force-induced linear actin polymerization and depolymerization via the formin Diaphanous and actin severing protein Cofilin, respectively. Importantly, these stretch-induced actomyosin cables stiffen the tissue to limit changes in cell shape and to protect the tissue from further mechanical damage prior to stress dissipation. This tissue rigidification prevents fractures in the tissue from propagating by confining the damage locally to the injured cells. Overall this mechanism of force-induced changes in tissue mechanical properties provides a general model of force buffering that rapidly protects tissues from physical damage to preserve tissue shape.
A Study on FBG Vehicle Loading Sensing System (2013)

This study considered the application of fiber Bragg grating (FBG) to a composite material leaf spring as a vehicle loading sensing system. The loading of the vehicle by the leaf spring was calculated by the period change of the fiber grating caused by deformation of the composite material leaf spring under loading. From the experiment results, a good linear relationship between loading and Bragg wavelength shift for light. The R-squared value for the linear regression reached 0.99. The loading sensitivity is about 0.267 nm/N.
The mitogen-activated protein kinome from Anopheles gambiae: identification, phylogeny and functional characterization of the ERK, JNK and p38 MAP kinases (2011)

The establishment of a MAPK "road map" based on the most advanced mosquito genome annotation can accelerate our understanding of host-pathogen interactions and broader physiology of An. gambiae and other mosquito species. Further, future efforts to develop predictive models of anopheline cell signaling responses, based on iterative construction and refinement of data-based and literature-based knowledge of the MAP kinase cascades and other networked pathways will facilitate identification of the "master signaling regulators" in biomedically important mosquito species.
