ns-O-RAN: Simulating O-RAN 5G Systems in ns-3 (2023)

O-RAN is radically shifting how cellular networks are designed, deployed and optimized through network programmability, disaggregation, and virtualization. Specifically, RAN Intelligent Controllers (RICs) can orchestrate and optimize the Radio Access Network (RAN) operations, allowing fine-grained control over the network. RICs provide new approaches and solutions for classical use cases such as on-demand traffic steering, anomaly detection, and Quality of Service (QoS) management, with an optimization that can target single User Equipments (UEs), slices, cells, or entire base stations. Such control can leverage data-driven approaches, which rely on the O-RAN open interfaces to combine large-scale collection of RAN Key Performance Measurements (KPMs) and state-of-the-art Machine Learning (ML) routines executed in the RICs. While this comes with the potential to enable intelligent, programmable RANs, there are still significant challenges to be faced, primarily related to data collection at scale, development and testing of custom control logic for the RICs, and availability of Open RAN simulation and experimental tools for the research and development communities. To address this, we introduce ns-O-RAN, a software integration between a real-world near-real-time RIC and an ns-3 simulated RAN which provides a platform for researchers and telco operators to build, test and integrate xApps. ns-O-RAN extends a popular Open RAN experimental framework (OpenRAN Gym) with simulation capabilities that enable the generation of realistic datasets without the need for experimental infrastructure. We implement it as a new open-source ns-3 module that uses the E2 interface to connect different simulated 5G base stations with the RIC, enabling the exchange of E2 messages and RAN KPMs to be consumed by standard xApps. Furthermore, we test ns-O-RAN with the O-RAN Software Community (OSC) and OpenRAN Gym RICs, simplifying the onboarding from a test environment to production with real telecom hardware controlled without major reconfigurations required. ns-O-RAN is open source and publicly available, together with quick-start tutorials and documentation.
γ-Mangostin fromGarcinia MangostanaPericarps as a Dual Agonist That Activates Both PPARα and PPARδ (2013)

We tested the peroxisome proliferator-activated receptor (PPAR)δ agonistic activity of a Garcinia mangostana pericarp extract to develop a treatment for the metabolic syndrome, and demonstrated γ-mangostin to be an active compound on the basis of a luciferase reporter gene assay. γ-Mangostin induced the expression of the uncoupling protein-3 (UCP-3) gene which is related to energy expenditure and fat metabolism in L6 cells. We showed that γ-mangostin is a dual agonist that activates both PPARδ and PPARα. γ-Mangostin also induced the expression of acyl-CoA synthase and carnitine palmitoyl-transferase 1A genes in HepG2 cells. These results suggest the potential of γ-mangostin as a preventive agent of the metabolic syndrome.
Manipulating Smith-Purcell radiation polarization with metasurfaces (2018)

Swift electrons moving closely to a periodic structure can generate far-field radiation. The radiated light is usually polarized in the direction of electron propagation. We have demonstrated manipulation of this polarization with properly designed metasurfaces.
Combating Jamming Attacks in Multi-channel IoT Networks Using Game Theory (2020)

Jamming attacks are among the most widely used techniques to block and disturb legitimate communications. Several techniques are used in the literature to combat these attacks. However, most of them either require the increase in transmission power or the implementation of complex coordination schemes which are not feasible in limited resources Internet of Things (IoT) devices. Therefore, in this paper, a defending strategy against jamming attacks is designed for health monitoring IoT networks with multiple Orthogonal frequency-division multiplexing (OFDM) slow fading channels. In particular, minimizing the worst case jamming effect on the IoT sensors communications is modeled as a Colonel Blotto game. By analyzing the Nash Equilibrium (NE) of the game, an anti-jamming power allocating strategy is proposed and is shown to be effective in combating jamming attacks without the need for extra power and resources.
ChemInform Abstract: Enhanced Oxygen Storage Capacity of Cerium Oxides in CeO2/La2O3/Al2O3 Containing Precious Metals. (1990)

Abstract Pt/Rh‐modified CeO2/Al 2 O 3 and CeO2/La2O3/Al 2 O 3 catalysts prepared by impregnation with an aqueous solution of H 4 PtCl 6 and RhCl 3 are found to have larger oxygen storage capacities (OSC) than the corresponding unmodified catalysts.
Image metric-based correction (Autocorrection) of motion effects: Analysis of image metrics (2000)

Magnetic resonance (MR) imaging of the shoulder necessitates high spatial and contrast resolution resulting in long acquisition times, predisposing these images to degradation due to motion. Autocorrection is a new motion correction algorithm that attempts to deduce motion during imaging by calculating a metric that reflects image quality and searching for motion values that optimize this metric. The purpose of this work is to report on the evaluation of 24 metrics for use in autocorrection of MR images of the rotator cuff. Raw data from 164 clinical coronal rotator cuff exams acquired with interleaved navigator echoes were used. Four observers then scored the original and corrected images based on the presence of any motion-induced artifacts. Changes in metric values before and after navigator-based adaptive motion correction were correlated with changes in observer score using a least-squares linear regression model. Based on this analysis, the metric that exhibited the strongest relationship with observer ratings of MR shoulder images was the entropy of the one-dimensional gradient along the phase-encoding direction. We speculate (and show preliminary evidence) that this metric will be useful not only for autocorrection of shoulder MR images but also for autocorrection of other MR exams.
Microwave Back-Projection Radar Surveillance System (2004)

Microwave back-projection radar techniques using transmitting and receiving array antennas have been developed for wide-area surveillance. This radar system contains two leaky coaxial cables as an antenna array, one for transmitting and one for receiving. The radar detects a trespasser by measuring the EM field level, which fluctuates when a trespasser approaches the area near the antennas, and passes through the surveillance area. In this research, we succeeded in specifying a trespass point by using the spread spectrum technique. Results from a field test proved that the detection algorithm could detect the motion of a trespasser without experiencing interference from shaking trees or rainfall.

NexPress moves to modularity and upgradeability and improves productivity (2006)

The Kodak NexPress 2100 digital production color press, available in 4/5 colors, based on electrophotographic print technology was first introduced at Drupa 2000 and has been improved since then. One of the highlights was the introduction of the Kodak NexPress fifth imaging unit solutions to extend the color gamut and image wise apply clear toner in combination with a near-line glossing unit.Meanwhile the machine platform was redesigned regarding productivity, modularity, upgradeability and open input/output resulting in the two new products, the Kodak NexPress 2100 plus and 2500 presses. The technical solutions to achieve these optimizations will be discussed in detail. The productivity was improved by higher speed and enhanced disposition of paper on the paper transport web resulting in print efficiency close to that of continuous web printing with same process speed. The print format size and the paper capability were improved as well. The paper feeding area is modular now allowing 2 &#x2013; 4 feeder with up to 11.000 sheets capacity. On the output side, there is now a new standard delivery unit that can be exchanged to one or two optional high-capacity delivery units using rotating stacker technology with proof tray. The 2100 plus is field upgradeable to the speed and other capabilities of the 2500 as well.
Amsterdam as a sustainable European metropolis: integration of water, energy and material flows (2015)

Heart and/or lung transplantation are life-saving treatments for end-stage cardiopulmonary disease; however, chronic renal failure may develop. The impact of thoracic organ transplant on renal function in infants and children is not well characterized. This retrospective cohort study evaluated renal function following thoracic organ transplantation in 46 children (32 heart, 9 lung, 5 heart-lung; median age 4.1 years) with at least 12 months of follow-up. Glomerular filtration rate (GFR, ml/min/1.73 m2) was estimated by the Schwartz formula throughout and each GFR estimate was converted to per cent normal for age (GFR%). Changes in renal function following transplantation were analyzed using longitudinal mixed-effects linear regression models. GFR% decreased following thoracic organ transplantation (p <0.001). Younger age at transplant was associated with a greater decline in GFR% (p <0.01). The decline in GFR% persisted after adjustment for nutritional status with body mass index or weight-for-length z-scores. The prevalence of renal insufficiency (GFR% <75) increased from 22% at transplant to 55% and 85% at 1 and 5 years post transplant, respectively, while 15% had a GFR% <50 at 5 years post transplantation. Higher tacrolimus trough levels over the first 6 months correlated with a lower GFR% (p <0.01). Renal function declined significantly following thoracic organ transplantation.

The Management of Spinal Injuries in Patients With Ankylosing Spondylitis or Diffuse Idiopathic Skeletal Hyperostosis (2009)

Although the rate of neurologic injury was high for both groups, AS patients were more likely to exhibit neurologic deficits and undergo operative management. Although the majority of these spinal injuries were treated surgically, stable fractures without any associated neurologic deficits were often successfully managed with immobilization. Complications were observed with both operative and nonoperative treatments, although all of the deaths occurred in conjunction with the use of the halo-vest orthosis.
Enhanced Dielectric Performance in Polymer Composite Films with Carbon Nanotube‐Reduced Graphene Oxide Hybrid Filler (2014)

The electrical conductivity and the specific surface area of conductive fillers in conductor-insulator composite films can drastically improve the dielectric performance of those films through changing their polarization density by interfacial polarization. We have made a polymer composite film with a hybrid conductive filler material made of carbon nanotubes grown onto reduced graphene oxide platelets (rG-O/CNT). We report the effect of the rG-O/CNT hybrid filler on the dielectric performance of the composite film. The composite film had a dielectric constant of 32 with a dielectric loss of 0.051 at 0.062 wt% rG-O/CNT filler and 100 Hz, while the neat polymer film gave a dielectric constant of 15 with a dielectric loss of 0.036. This is attributed to the increased electrical conductivity and specific surface area of the rG-O/CNT hybrid filler, which results in an increase in interfacial polarization density between the hybrid filler and the polymer.

Optimal ZVS Modulation of Single-Phase Single-Stage Bidirectional DAB AC–DC Converters (2014)

A comprehensive procedure for the derivation of optimal, full-operating-range zero voltage switching (ZVS) modulation schemes for single-phase, single-stage, bidirectional and isolated dual active bridge (DAB) ac-dc converters is presented. The converter topology consists of a DAB dc-dc converter, receiving a rectified ac line voltage via a synchronous rectifier. The DAB comprises primary and secondary side full bridges, linked by a high-frequency isolation transformer and a series inductor. ZVS modulation schemes previously proposed in the literature are either based on current-based or energy-based ZVS analyses. The procedure outlined in this paper for the calculation of optimal DAB modulation schemes (i.e., combined phase-shift, duty-cycle, and switching frequency modulation) relies on a novel, more accurate, current-dependent charge-based ZVS analysis, taking into account the amount of charge that is required to charge the nonlinear parasitic output capacitances of the switches during commutation. Thereby, the concept of “commutation inductance(s)” is shown to be an essential element in achieving full-operating-range ZVS. The proposed methods are applied to a 3.7 kW, bidirectional, and unity power factor electric vehicle battery charger which interfaces a 400 V dc-bus with the 230 Vac, 50-Hz utility grid. Experimental results obtained from a high-power-density, high-efficiency converter prototype are given to validate the theoretical analysis and practical feasibility of the proposed strategy.
Source Estimation of Auditory Brainstem Evoked Potentials: Comparison of 3CLT and Dipole Localization (1995)

The generators of auditory brainstem evoked potentials (ABEPs) are generally agreed to be located between the auditory nerve and upper pons. Thus, they are all located within a few cm from the center of the head. Three-channel Lissajous' trajectory (3CLT) provides the amplitude and orientation of a centrally located equivalent dipole of surface recorded activity. Volume conductor theory predicts decreased spatial resolution of source estimation the deeper the source. In this study we compared source estimates obtained with 3CLT, using three orthogonal differential channels, with those obtained with two other source estimation methods: i) setting the generators at their known anatomical coordinates and calculating orientation and magnitude of the source (dipole localization method--DLM); ii) estimation of all source parameters, including the number of sources by wavelet-type decomposition, without assumptions on the location of the sources (multiple source estimate--MSE). 3CLT, DLM and MSE all converged on magnitudes and orientations that were not significantly different from each other, and locations that were within a few cm of each other. In conclusion, although 3CLT can only estimate a single, centrally located equivalent dipole, in the specific case of ABEPs, it provides the same information available from the more demanding source estimate methods. In addition to the considerable saving in recording channels, 3CLT is reference-independent and thus avoids ambiguities resulting from the choice of reference.
Exploring the pathophysiology of post-sepsis syndrome to identify therapeutic opportunities (2020)

Sepsis is a major health problem worldwide. As the number of sepsis cases increases, so does the number of sepsis survivors who suffer from "post-sepsis syndrome" after hospital discharge. This syndrome involves deficits in multiple systems, including the immune, cognitive, psychiatric, cardiovascular, and renal systems. Combined, these detrimental consequences lead to rehospitalizations, poorer quality of life, and increased mortality. Understanding the pathophysiology of these issues is crucial to develop new therapeutic opportunities to improve survival rate and quality of life of sepsis survivors. Such novel strategies include modulating the immune system and addressing mitochondrial dysfunction. A sepsis follow-up clinic may be useful to identify long-term health issues associated with post-sepsis syndrome and evaluate existing and novel strategies to improve the lives of sepsis survivors.

ML estimation of timing and frequency offset in multicarrier systems (1996)

In this paper, we present a novel data-based method for simultaneous Maximum Likelihood (ML) symbol and carrier-frequency offset estimation in Orthogonal frequencydivision multiplexing (OFDM) systems. Statistical properties introduced by the cyclic prefix, a guard space between OFDM symbols, provide sufficient information about the unknown parameters. It is shown that the redundancy introduced by this cyclic prefix allows the estimation to be performed without additional pilots. Simulations show that the performance of the frequency estimator is applicable in a tracking mode while the timing estimation can be used in an acquisition mode.
Deploying CommunityCommands: A Software Command Recommender System Case Study (2014)

In 2009 we presented the idea of using collaborative filtering within a complex software application to help users learn new and relevant commands (Matejka et al. 2009). This project continued to evolve and we explored the design space of a contextual software command recommender system and completed a four-week user study (Li et al. 2011). We then expanded the scope of our project by implementing CommunityCommands, a fully functional and deployable recommender system. CommunityCommands was made available as a publically available plug-in download for Autodesk‟s flagship software application AutoCAD. During a one-year period, the recommender system was used by more than 1100 AutoCAD users. In this paper, we present our system usage data and payoff. We also provide an in-depth discussion of the challenges and design issues associated with developing and deploying the front end AutoCAD plug-in and its back end system. This includes a detailed description of the issues surrounding cold start and privacy. We also discuss how our practical system architecture was designed to leverage Autodesk‟s existing Customer Involvement Program (CIP) data to deliver in-product contextual recommendations to endusers. Our work sets important groundwork for the future development of recommender systems within the domain of end-user software learning assistance.

An Intramolecular Titanium-Catalyzed Asymmetric Pauson−Khand Type Reaction1 (1999)

The development of the first catalytic asymmetric Pauson−Khand type cyclization of enynes is described. The active catalyst, (S,S)-(EBTHI)Ti(CO)2 (1), is generated in situ from (S,S)-(EBTHI)TiMe2 (2). A variety of 1,6-enynes can be converted to the corresponding cyclopentenones in high yield (70−94%) with excellent ee's (87−96%). Limitations of the catalyst with respect to substrate structure are discussed. The absolute configurations of several of the enone products have been ascertained, and these assignments represent a reversal with respect to an assignment in the initial report. A rationale for the sense and levels of enantioselectivity for this catalyst is proposed.
