Static and dynamic resource allocation algorithms for real-time VBR video transmissions in multimedia networks (2002)

We present two resource reservation schemes which are intended for different real-time VBR video application scenarios with different resource requirements. The static scheme makes a CBR reservation based on a target rate while the dynamic scheme relies on the RCBR service to achieve an efficient resource utilization. In each scheme, a traffic smoothing process is employed to regulate the video traffic such that it ensures video display continuity and meets the resource restrictions imposed by the application or the network. The smoothing algorithms are directly adapted from some smoothing optimization methods for stored videos with additional considerations of the real-time requirements. Quantization controls are initiated only when the smoothing results are known or are likely to violate the resource restrictions in the future.
Magnetic and magnetoresistance behaviors of particulate iron/vinyl ester resin nanocomposites (2008)

Magnetoresistance (MR) behavior of vinyl ester monomer stabilized iron nanoparticles and heat-treated vinyl ester resin nanocomposites reinforced with iron nanoparticles were investigated. Vinyl ester monomer serves as a coupling agent with one side covalently bound onto the nanoparticle surface by a displacement reaction and the other end copolymerized with extra vinyl ester resin to form a robust entity. The particle loading and type of material (polymer or carbonized polymer) have a significant effect on the magnetic and MR properties. The heat-treated nanocomposites follow a tunneling conduction. After reduction annealing, the obtained nanocomposites possess a room temperature MR of 8.3 % at a field of 90 kOe.
Fiber-Integrated Absorption Spectroscopy Using Liquid-Filled Nanobore Optical Fibers (2018)

Absorption spectroscopy represents one highly relevant approach in current analytics to non-invasively characterize liquid analytes. Here we present the concept of waveguide-integrated absorption spectroscopy via nanobore optical fibers. Using a liquid-filled nanochannel inside the core of a microstructured step-index fiber, the spectroscopic characteristics of liquid analytes located inside the nanochannel are imprinted onto the propagating mode via its evanescent fields, allowing to conduct absorption spectroscopic experiments at extremely small sample volume levels. We reveal the limits of this spectroscopic approach by analyzing the dependence of the power fraction inside the bore on the fiber parameters and experimentally demonstrate its capabilities by 1) using the cut-back technique using an optofluidic mount and 2) fully encapsulating a highly doped dye solution inside the nanobore fiber. Based on its high degree of integration and the straightforward handling capabilities, application of the nanobore fiber based absorption spectroscopy concept can be anticipated in fields, such as bioanalytics, analytical chemistry, and environmental science.

Tailoring the duobinary pulse shape for optimum performance (2005)

This paper presents an experimental investigation on the optimum optical duobinary system for amplified spontaneous emission (ASE)-noise-limited transmission at 10 Gb/s. Optical filtering is used at the transmitter and receiver to optimize the duobinary pulse shape, while suppressing the effects of ASE noise. The optimized system shows excellent ASE-noise-limited performance, approaching to within 3.4 dB of the theoretical matched filter limit for the duobinary system.

Biological and clinical significance of cathepsin D in breast cancer. (1990)

Cathepsin D is an acidic lysosomal protease present in all cells. In breast cancer cells, pro-cathepsin D expression and secretion are markedly increased and its processing is altered. This protease is induced by estrogens and growth factors. In vitro, pro-cathepsin D is an autocrine mitogen on breast cancer cells and can be auto-activated to degrade extracellular matrix and proteoglycans in acidic microenvironment. In patients, there is a significant correlation between high cathepsin D concentrations in the cytosol of primary breast cancer and development of metastasis. This marker is independent of other prognostic factors and appears to be particularly useful in lymph node-negative tumors. These results suggest that derouting and overexpression of cathepsin D plays an important role in invasion and metastasis of breast cancer cells.
High-efficiency and solution processible multilayer white polymer light-emitting diodes using neutral conjugated surfactant as an electron injection layer (2008)

High-efficiency white polymer light-emitting diodes were fabricated by using an yellow-emitting osmium complex Os(fptz)2(dppe) [fptz=3-trifluoromethyl-5-(2-pyridyl)-1,2,4-triazole, dppe=cis-1,2-bis-(dipheneyl-phosphino) ethylene] doped into blue fluorescent copolymer based on an ultraviolet-blue light emitting host poly[2,7-(9,9-dioctylfluorene)-co-1,3-(5-carbazolphenylene)] and a blue light emitting component 4-N,N-diphenylaminostilbene (PFCz-DPS1-OXD5) as the emissive layer and a neutral conjugated surfactant, poly[9,9-bis(6′(diethanolamino)hexyl)-fluorene] (PFN-OH), as the electron injection layer sandwiched between the emissive layer and Al cathode. The device with the configuration of indium tin oxide/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid)/poly(N-vinylcarbazole)/Os(fptz)2(dppe)(1wt%):PFCz-DPS1-OXD5∕PFN-OH∕Al exhibited efficient white light emission at the Commission Internationale de I’Eclairage coordinates of (0.33, 0.34) and a maximum luminance efficiency of 16.9cd∕A and brightness of 22100cd∕m2.
Advanced Glycation End Product Free Adducts Are Cleared by Dialysis (2005)

Plasma advanced glycation end product (AGE) free adducts are increased up to 50-fold among patients on dialysis. We examined the ability of hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) to clear these compounds. The AGE free adducts Nepsilon-carboxymethyl-lysine (CML) and Nepsilon-(1-carboxyethyl)lysine (CEL) and the hydroimidazolones derived from glyoxal (G-H1), methylglyoxal (MG-H1), and 3-deoxyglucosone (3DG-H) were determined by LC-MS/MS and pentosidine by HPLC with fluorimetric detection in ultrafiltrates of plasma, urine, or PD effluent as appropriate from patients on HD (n = 8) or PD (n = 8), and from healthy controls (n = 8). Among patients on HD, all free AGEs predialysis were significantly higher than in controls and were decreased with dialysis. The removal of MG-H1 and 3DG-H was comparable to that of urea, whereas that of CML and pentosidine was some 20% higher; in contrast, the removal of CEL and G-H1 was 25% lower. Among patients on CAPD, free AGEs in PD effluent increased with increasing dwell time. The combined renal and peritoneal 24-h excretion rates of CML (4.7 micromol), CEL (6.5 micromol), 3DG-H (16.6 micromol), and pentosidine (0.08 micromol) were twofold higher than the amount excreted in healthy controls, whereas MG-H1 was ninefold higher (59 micromol); the combined clearances of all free AGEs except pentosidine were lower than in healthy controls. Impaired renal clearance contributes to increased plasma free AGEs in uremia, but the increased excretion rate among patients on PD demonstrates that there was also an increased synthesis of free AGEs. Both HD and PD are able to remove free AGEs.
Two Novel On-policy Reinforcement Learning Algorithms based on TD(λ)-methods (2007)

This paper describes two novel on-policy reinforcement learning algorithms, named QV(λ)-learning and the actor critic learning automaton (ACLA). Both algorithms learn a state value-function using TD(λ)-methods. The difference between the algorithms is that QV-learning uses the learned value function and a form of Q-learning to learn Q-values, whereas ACLA uses the value function and a learning automaton-like update rule to update the actor. We describe several possible advantages of these methods compared to other value-function-based reinforcement learning algorithms such as Q-learning, Sarsa, and conventional actor-critic methods. Experiments are performed on (1) small, (2) large, (3) partially observable, and (4) dynamic maze problems with tabular and neural network value-function representations, and on the mountain car problem. The overall results show that the two novel algorithms can outperform previously known reinforcement learning algorithms
Challenging the Feasibility and Clinical Significance of Current Guidelines on Lymph Node Examination in Rectal Cancer in the Era of Neoadjuvant Therapy (2011)

In a tertiary cancer center, the 12-LN threshold was not relevant and often not achievable in patients with RC treated with neoadjuvant therapy. Lower LN count after neoadjuvant treatment was not associated with understaging or inferior survival. Although we support the critical importance of careful pathologic examination and adequate nodal staging, we challenge the relevance of LN count both in clinical practice and as a quality indicator in RC.
Morphological transformation and tumorigenicity in C3H/10T1/2 cells transformed with an inducible c-Ha-ras oncogene (1987)

A C3H/10T1/2 cell line containing an inducible metallothionein-ras hybrid oncogene was conditionally and reversibly transformed upon exposure to zinc ions. Interestingly, although the cell line was fully malignant when expressing only low levels of ras, complete morphological transformation required much higher levels.
Developing empirical correlations for frost thickness and air face velocity degradation for microchannel heat exchangers used in heat pump applications under frosting conditions (2013)

This study experimentally investigated the frost growth on louvered folded fins in outdoor microchannel heat exchangers used in air-source heat pump systems. The effects of surface temperature and fin geometries on the performance of the microchannel heat exchangers under frosting condition were studied. Seven fin samples with various fin widths, fin heights, and fin densities and a louver angle of approximately 30° were tested in controlled laboratory conditions that replicated those of actual heat pump systems in the winter season. The fin surface temperature was experimentally measured with the novel methodology developed in the present study. Experimental data of local frost thickness, air pressure drop across the coils, time of frost–defrost cycles, and heat transfer rates were recorded for heat exchangers operating in actual transient frosting conditions. Data showed that frosting time and frost growth rates depended mainly on the local fin surface temperature. A set of empirical correlations were developed to predict the frost thickness on the fin leading edge and the reduction of air face velocity due to air pressure drop across the frosted coil during frosting operation. The correlations were compared against experimental data of frost collected in the present study, and satisfactory agreement was achieved. The frost thickness correlation and air face velocity correlations aid in the calculation of the instantaneous air-side Reynolds numbers during frosting operation of the fin samples. These are critical for predicting the heat transfer rates of the microchannel coils in quasi-steady-state frosting operating conditions.
Practical Attribute-Based Multi-Keyword Search Scheme in Mobile Crowdsourcing (2017)

Cloud-based mobile crowd-sourcing has been an attractive solution to provide data storage and share services for resource-limited mobile devices in a privacy-preserving manner, but how to enable mobile users to issue search queries and achieve fine-grained access control over ciphertexts simultaneously is still a big challenge for various circumstances. Although the ciphertext-policy attribute-based keyword search technology combining attribute-based encryption with searchable encryption has become a hot research topic, it just deals with equivalent attributes rather than more practical attribute comparisons, like “greater than” or “less than.” In this paper, we devise a practical cryptographic primitive called attribute-based multi-keyword search scheme to support comparable attributes through utilizing 0-encoding and 1-encoding. Formal security analysis proves that our scheme is selectively secure against chosen-keyword attack in generic bilinear group model and extensive experiments using real-world dataset demonstrate that our scheme can drastically decrease both computational and storage costs.
Life Cycle Economic and Environmental Implications of Using Nanocomposites in Automobiles (2003)

By reducing the energy and materials required to provide goods and services, nanotechnology has the potential to provide more appealing products while improving environmental performance and sustainability. Whether and how soon this potential could be realized depends on phrasing the right research and development (R&D) questions and pursuing commercialization intelligently. A sufficiently broad perspective at the outset is required to understand economic and technical feasibility, estimate life cycle environmental implications, and minimize unanticipated negative impacts. The rapid rise in federally funded nanotechnology R&D dictates that consideration of societal benefits will have a large role in setting the R&D agenda. We estimate potential selected economic and environmental impacts associated with the use of nanotechnology in the automotive industry. In particular, we project the material processing and fuel economy benefits associated with using a clay-polypropylene nanocomposite instead of steel or aluminum in light-duty vehicle body panels. Although the manufacturing cost is currently higher, a life cycle analysis shows potential benefits in reducing energy use and environment discharges by using a nanocomposite design.
Pregnant and breastfeeding women’s prospective acceptability of two biomedical HIV prevention approaches in Sub Saharan Africa: A multisite qualitative analysis using the Theoretical Framework of Acceptability (2021)

HIV infection during pregnancy and breastfeeding has implications for maternal health. Between May- November 2018, we explored prospective acceptability of two novel HIV Pre-exposure Prophylaxis (PrEP) products, oral pills and vaginal rings, through focus group discussions with 65 pregnant and breastfeeding women in Malawi, South Africa, Uganda, Zimbabwe. Qualitative analysis was completed, guided by the Theoretical Framework of Acceptability (TFA). First, a deductive thematic analysis was applied to relevant coded data, into the seven TFA constructs (Affective Attitude; Burden; Ethicality, Intervention Coherence; Opportunity Costs; Perceived Effectiveness; Self-efficacy). Next, an iterative analysis was completed to generate themes within each of the TFA constructs. Women's positive attitudes towards daily oral PrEP highlighted the familiarity of taking pills, understanding the purpose of taking pills, and the perception that it is an effective method to protect mothers and babies from HIV during pregnancy and breastfeeding. Women emphasized the ease of using the ring given its monthly duration that lowers burden on the user, its discreetness and invisibility once in place. The TFA analysis highlighted how acceptability of both methods could be enhanced by focusing on perceptions of the end users (i.e. the women) and not just the products themselves. This approach provided insights into how to refine the intervention materials and plans for implementation.
Urgency-driven, plug-in electric vehicle charging (2012)

In this work, we propose a strategy for managing the charging of plug-in electric vehicles (PEVs) that simultaneously avoids overloads and provides demand-based allocation of power distribution resources. The strategy leverages (1) a `power packet' approach which allocates charging for finite lengths of time and (2) a locally defined automaton where a user's `urgency' sets the request rate for charging. The charge management strategy requires very little communications between the PEV charger and the power distribution system. Furthermore, the system's charge manager is blind to which PEV is making the request thereby ensuring fairness and privacy. The work details possible implementations of the approach and illustrates the methodology through simulations.

Matrix Vesicles-Containing Microreactors as Support for Bonelike Osteoblasts to Enhance Biomineralization (2018)

Therapeutic cell mimicry aims to provide a source of cell-like assemblies, which exhibit the core structural or functional properties of their natural counterparts with broad envisioned applications in biomedicine. Bone tissue engineering (BTE) aims at promoting and inciting the natural healing process of, for instance, critically sized bone defects. Microreactors designed to co-assemble with biological bone-forming osteoblasts like SaOS-2 cells to start biomineralization are reported for the first time. The alginate-based microparticles are equipped with active alkaline phosphatase-loaded artificial liposomes or SaOS-2-derived matrix vesicles (MVs). Spheroids assembled from SaOS-2 cells and microreactors not only exhibit higher cell viability, but also show enhanced biomineralization when MVs are present. The active biomineralization stimulation of the microreactors is illustrated by colorimetric calcium quantification and micro-computed tomography. These findings show the promising potential of applying cell mimicry in BTE.
Fort Chaffee Revisited: The Epidemiology of Tick-Borne Rickettsial and Ehrlichial Diseases at a Natural Focus (2001)

A retrospective cohort study was conducted among troops training at Fort Chaffee, Arkansas, from May through June 1997, to identify infections caused by tick-borne pathogens. Serum samples were tested by IFAs for antibodies to selected Rickettsia and Ehrlichia species and by an investigational EIA for spotted fever group Rickettsia lipopolysaccharide antigens. Of 1,067 guardsmen tested, 162 (15.2%) had antibodies to one or more pathogens. Of 93 guardsmen with paired serum samples, 33 seroconverted to Rickettsia rickettsii or spotted fever group rickettsiae (SFGR) and five to Ehrlichia species. Most (84.8%) of the personnel who seroconverted to SFGR were detected only by EIA, and seropositivity was significantly associated with an illness compatible with a tick-borne disease. In addition, 34 (27%) of 126 subjects with detectable antibody titers reported a compatible illness. The primary risk factor for confirmed or probable disease was finding > 10 ticks on the body. Doxycycline use and rolling up of long sleeves were protective against seropositivity. The risk of transmission of tick-borne pathogens at Fort Chaffee remains high, and use of the broadly reactive EIA suggests that previous investigations may have underestimated the risk for infection by SFGR. Measures to prevent tick bite and associated disease may require reevaluation.
Synthesis of deuterium labeled cannabinoids (1988)

Abstract Several methods for the specific deuteration of cannabinoids are described. Deuteration of the phenolic ring was accomplished by treatment with BF 3 . Et 2 O followed by quenching with a solution of Na 2 CO 3 in D 2 O resulting in deuterium incorporation in both the 2 and 4 positions. Regioselective incorporation of deuterium into either the 2 or 4 position of Δ 8 ‐THC was achieved using Florisil spiked with either D 2 O or H 2 O. Deuteration at positions 8, 10 and 11 was achieved by addition of DCI gas to the appropriate tetrahydrocannabinol to form 9‐chlorohexahydrocannabinol labeled at either of the above positions, followed by elimination of hydrogen‐ or deuterium chloride with potassium‐tert‐amylate. UV irradiation of specifically labeled Δ 8 ‐THC gave the correspondingly labeled Δ 9,11 ‐THC.
Time/frequency analysis of respiratory mechanics via amplitude modulation of multiple carriers (2002)

Time/frequency analysis of nonstationary linear dynamic systems is usually performed using the short-time fast Fourier transform or the wavelet transform. An alternative approach is presented here in which the system to be identified is excited with a superposition of distinct sinusoids, each of which is amplitude-modulated in the output by the time-varying system dynamics. Each component is then filtered out and demodulated separately by application of a recursive time-domain model. The method is applied to the analysis of changing respiratory system impedance simulated by a two-compartment model of the lungs.
