Synthesis of mycocerosic acids from methylmalonyl coenzyme A by cell-free extracts of Mycobacterium tuberculosis var. bovis BCG. (1983)

Multimethyl-branched acids extracted from the cells of Mycobacterium tuberculosis var. bovis BCG were identified by combined capillary gas-liquid chromatography and mass spectrometry. These mycocerosic acids consisted of the products expected from elongation of n-C18 and n-C20 primers with methylmalonyl-CoA. A soluble enzyme preparation from M. tuberculosis var. bovis BCG incorporated methylmalonyl-CoA into mycocerosic acids. This incorporation was partially dependent on the addition of arachidoyl-CoA and this primer affected product distribution, indicating elongation of the primer. Maximal incorporation of methylmalonyl-CoA required the presence of both NADPH and NADH together with ATP and Mg2+. Added CoA, FMN, acyl carrier protein, or bovine serum albumin had no effect on the activity in either the presence or absence of ATP and Mg2+. The pH optimum for mycocerosic acid synthesis was 6.2. Under these conditions, methylmalonyl-CoA was incorporated into very long acids which were identified as mycocerosic acids by radio gas-liquid chromatography.
Dynamic Resource Allocation in Co-Located and Cell-Free Massive MIMO (2019)

In this paper, we study joint power control and scheduling in uplink massive multiple-input-multiple-output (MIMO) systems with randomly arriving data traffic. We consider both co-located and Cell-Free (CF) Massive MIMO, where the difference lies in whether the antennas are co-located at the base station or spread over a wide network area. The data is generated at each user according to an individual stochastic process. Using Lyapunov optimization techniques, we develop a dynamic scheduling algorithm (DSA), which decides at each time slot the amount of data to admit to the transmission queues and the transmission rates over the wireless channel. The proposed algorithm optimizes the long-term user throughput under various fairness policies while keeping the transmission queues stable. Simulation results show that the state-of-the-art power control schemes developed for Massive MIMO with infinite backlogs can fail to stabilize the system even when the data arrival rates are within the network capacity region. Our proposed DSA shows advantage in providing finite delay with performance optimization whenever the network can be stabilized.
Multifunctional Nanoparticles for Photothermally Controlled Drug Delivery and Magnetic Resonance Imaging Enhancement (2008)

Core–multishell nanoparticles: Near-IR-resonant rhodamine-encapsulated poly(lactic-co-glycolic acid) (PLGA)–Mn/Au half-shell nanoparticles (NPs; see figure) are developed by depositing metal multilayers on PLGA NPs. These NPs can be used for photothermally controlled drug delivery and magnetic resonance imaging. Upon NIR irradiation, the release rate of rhodamine from the PLGA NPs is about twice as great as that without NIR irradiation, indicating photothermally controlled drug delivery possibilities.
Linkage analysis of bipolar illness with X‐chromosome DNA markers: A susceptibility gene in Xq27‐q28 cannot be excluded (1994)

Transmission studies have supported the presence of a susceptibility gene for bipolar (BP) illness on the X-chromosome. Initial linkage studies with color blindness (CB), glucose-6-phosphate dehydrogenase (G6PD) deficiency, and the blood coagulation factor IX (F9) have suggested that a gene for BP illness is located in the Xq27-q28 region. We tested linkage with several DNA markers located in Xq27-q28 in 2 families, MAD3 and MAD4, that previously were linked to F9 and 7 newly ascertained families of BP probands. Linkage was also examined with the gene encoding the alpha 3 subunit of the gamma-amino butyric acid receptor (GABRA3), a candidate gene for BP illness located in this region. The genetic data were analyzed with the LOD score method using age-dependent penetrance of an autosomal dominant disease gene and narrow and broad clinical models. In MAD3 and MAD4 the multipoint LOD score data suggested a localization of a BPI gene again near F9. In the 7 new families the overall linkage data excluded the Xq27-q28 region. However, if the families were grouped according to their proband's phenotype BPI or BPII, a susceptibility gene for BPI disorder at the DXS52-F8 cluster could not be excluded.
An Empirical Normal Mode Diagnostic Algorithm Applied to NCEP Reanalyses (2002)

A diagnostic algorithm, based on the empirical normal mode decomposition technique, is proposed as a diagnostic tool in studies of the atmospheric variability. It begins by analyzing the transient eddies in terms of empirical modes that are orthogonal with respect to wave activities. Time-dependent amplitudes together with wave activity spectra are used to classify the modes and compute their propagation properties. The algorithm is applied to a sequence of four Northern Hemisphere winters taken from the National Centers for Environmental Prediction reanalyses, with a focus on the upper troposphere and lower stratosphere, giving a set of empirical modes of wind, pressure, specific volume, and potential vorticity. Results indicate that most of the wave activity is carried by large-scale, eastward-propagating modes centered at middle and high latitudes. Some properties of the leading modes, such as their average phase speeds, are in good agreement with the predictions of linear dynamics. Characteristics of the leading wavenumber-5 mode, such as its dipolar pressure pattern near the summer hemisphere tropopause, its propagation speed of 12 m s−1 and decay rate of 3 days, can be explained by the theory of quasi modes, defined as superpositions of singular modes sharply peaked in the phase speed domain. Other large-scale, midlatitude modes also show properties compatible with the quasi-modal description, suggesting that quasi modes play an important role in the upper-troposphere dynamics.

Optical Properties of the (Y,Gd)BO3:Eu3+Phosphor Coated with SiO2Nano Particles (2009)

In order to improve the luminance of red emission of the (Y,Gd)BO3:Eu3+ phosphors were coated with SiO2 nano particles. It was revealed that the surface coating of phosphors with SiO2 leads to an increase in luminance intensity. This seems to be due to the increase of the excitation light which is transmitted into the phosphor, i.e., an effective vacuum ultraviolet absorption of the phosphor via SiO2 nano particles. The experimental results suggest that the surface coating of phosphors with SiO2 nano particles is a way to improve the luminance.
Design and hardware-in-the-loop test of the embedded control system of an indoor quadrotor helicopter (2008)

The paper deals with the quick prototype design and hardware-in-the-loop real-time test of the embedded control system of an indoor miniature quadrotor helicopter (UAV) before first flight. The control law is of backstepping type, the sensory system consists of a marker-based vision system outside the helicopter in radio connection with the embedded controller and a 3D inertial measurement unit (IMU) on the helicopter. Extended Kalman filters solve the state estimation problem. Brushless DC motors serve as actuators. For quick prototype design of the embedded controller MATLAB, Simulink, Real-Time Workshop and the MPC555 Target Compiler were used. Because of the critical character of the control of flying systems the whole embedded control system was hardware-in-the-loop tested by using DS1103 of dSPACE for real-time emulation of the indoor helicopter. During test the helicopter and the sensors were mapped to DS1103 and the test was performed in real-time using the helicopter and sensor models. Communication during the test was running using CAN bus protocol between the Freescale MPC555 processor of the embedded controller and the emulation of the helicopter and the sensors on DS1103.
Setting global standards in adult echocardiography: Where are we? (2015)

Echocardiography is a widely utilized cardiac imaging modality.However, despite the vast array of diagnostic capabilities, the generally subjective nature of interpretation necessitates high degree of operator expertise to ensure diagnostic accuracy of the interpretations.Imaging guidelines and performance standards are therefore an integral component of echocardiography training and are required to ensure consistency of imaging and accuracy of the interpretations.To meet this objective, International societies like the American Society of Echocardiography (ASE) and European Association of Cardiovascular Imaging (EACVI) have over the years developed consensus statements and recommendations for all the clinically relevant aspects of cardiac ultrasound and its application.Although these recommendations are adopted for echocardiography practices globally, such approaches have the limitation of overlooking the challenges that are unique to the practice of echocardiography in different parts of the world.The present commentary discusses some of the challenges that are unique for the Indian subcontinent and focus on the guideline documents related to three commonest indications for performing echocardiography-cardiac chamber quantification, 1,2 evaluation of valve diseases 3,4 and assessment of left ventricular (LV) diastolic function.
Deformation-free overgrowth of reactive ion beam etched submicron structures in InP by liquid phase epitaxy (1986)

Submicron grating patterns written by electron beam lithography are transferred into InP substrates by reactive ion beam etching (RIBE) using an Ar/O2 gas mixture. Trapezoidal grating structures with a depth of 0.15 μm are generated. The influence of the preheating cycle prior to liquid phase epitaxy (LPE) on the grating shape is investigated as a function of different cover materials. We obtain deformation-free LPE overgrowth of the dry etched corrugations applying the GaAs cover technique. In contrast to wet chemically etched gratings identical grating profiles are formed in different crystallographic directions by RIBE and successfully overgrown by LPE.
Rapid and specific detection of F17-related pilin and adhesin genes in diarrheic and septicemic Escherichia coli strains by multiplex PCR (1996)

The F17-related adhesins are prevalent in Escherichia coli strains isolated from calves with diarrhea or septicemia and from lambs with nephropathy. The F17 family includes the F17a, F17b, F17c, and F111 fimbriae produced by bovine E. coli strains and the G agglutinin produced by human uropathogenic E. coli strains. An easy and inexpensive multiplex PCR method was developed to detect all the F17-related fimbriae and to identify four subtypes of structural subunit genes and two distinct subfamilies of adhesin genes by only two runs of amplification. A strict correlation was observed between the phenotypic assays and the multiplex PCR method when 166 pathogenic E. coli strains isolated from intestinal content of calves or lambs were tested. Genes encoding the F17c structural subunit and the subfamily II adhesins were prominent among the bovine and ovine isolates, and the capsule-like CS31A antigen was strictly associated with the F17c fimbriae. The F17b subtype fimbriae were prominent among the bovine isolates producing the CNF2 toxin, whereas the F17a subtype fimbriae were associated with the bovine isolates producing neither the CS31A antigen nor the CNF2 toxin. Five bacterial strains possessed two distinct and complete F17-related fimbrial gene clusters, and two of them produced two F17-related fimbriae at the bacterial cell surface. The related fimbrial gene clusters are probably organized in mosaic operons consisting of F17-related pilin and adhesin genes, and horizontal gene transfer may occur among E. coli strains isolated form different animal species.

Wireless Internet access using anonymous access methods (2003)

Accessing the Internet from a mobile computer can currently be done by opening a circuit switched call to the ISP (Internet service provider). New packet based services are now being introduced, such as the GPRS (General Packet Radio Service) for the GSM system. The solution described gives a simpler access to the Internet, at the same time providing complete user anonymity. However, the solution here does not exclude the use of traditional accounting methods, or more sophisticated electronic cash solutions which do not provide anonymity at the same level, as the solution described here. A MH (mobile host) attaching to a visited radio network receives an IPv6 address prefix from the access router in the visited network. The MH configures the whole IPv6 address for its interface. After initialization, it starts paying for the radio and Internet access to the visited radio operator. Paying method is e-cash, providing full anonymity for the mobile user. After receiving access to the network, the mobile user registers its current location information on a location server (dynamic DNS or some other), so that other hosts can resolve the mobile user's current IPv6 address and contact the roaming mobile user. The same e-cash, which is used to pay for the network access, will be used to buy services provided in the network. Services can be either local or global. Local service could be, for example, buying a soda, global such as receiving a video stream from a video server.
Expert System for Bridge Scour and Stream Stability (1994)

Significant engineering judgment is required to ascertain the scour susceptibility of bridges. This judgment is typically acquired through many years of experience. This paper describes the development of an expert system that encodes the expertise of knowledgeable individuals in hydraulic, geomorphic, structural and geotechnical engineering and bridge maintenance to aid bridge inspectors in evaluating scour potential and stream stability.
Cholelithiasis of the ovary (1993)

The pathologic consequences of pelvic cholelithiasis can be marked. This was demonstrated in a postmenopausal woman, but has direct implications for the premenopausal patient as well. Our experience suggests that gallstones lost during laparoscopic cholecystectomy should be removed if possible.
Intelligent Intersection: Two-Stream Convolutional Networks for Real-time Near Accident Detection in Traffic Video (2019)

In Intelligent Transportation System, real-time systems that monitor and analyze road users become increasingly critical as we march toward the smart city era. Vision-based frameworks for Object Detection, Multiple Object Tracking, and Traffic Near Accident Detection are important applications of Intelligent Transportation System, particularly in video surveillance and etc. Although deep neural networks have recently achieved great success in many computer vision tasks, a uniformed framework for all the three tasks is still challenging where the challenges multiply from demand for real-time performance, complex urban setting, highly dynamic traffic event, and many traffic movements. In this paper, we propose a two-stream Convolutional Network architecture that performs real-time detection, tracking, and near accident detection of road users in traffic video data. The two-stream model consists of a spatial stream network for Object Detection and a temporal stream network to leverage motion features for Multiple Object Tracking. We detect near accidents by incorporating appearance features and motion features from two-stream networks. Using aerial videos, we propose a Traffic Near Accident Dataset (TNAD) covering various types of traffic interactions that is suitable for vision-based traffic analysis tasks. Our experiments demonstrate the advantage of our framework with an overall competitive qualitative and quantitative performance at high frame rates on the TNAD dataset.
Functional modular contact lens (2009)

Tear fluid offers a potential route for non-invasive sensing of physiological parameters. Utilization of this potential depends on the ability to manufacture sensors that can be placed on the surface of the eye. A contact lens makes a natural platform for such sensors, but contact lens polymers present a challenge for sensor fabrication. This paper describes a microfabrication process for constructing sensors that can be integrated into the structure of a functional contact lens in the future. To demonstrate the capabilities of the process, an amperometric glucose sensor was fabricated on a polymer substrate. The sensor consists of platinum working and counter electrodes, as well as a region of indium-tin oxide (ITO) for glucose oxidase immobilization. An external silver-silver chloride electrode was used as the reference electrode during the characterization experiments. Sensor operation was validated by hydrogen peroxide measurements in the 10- 20 &mu;M range and glucose measurements in the 0.125-20 mM range.
Improvement of various properties of fiber surfaces containing crosslinked polyethylene glycols (1989)

Abstract Modification of a variety of fabric and fibrous surfaces was achieved by insolubilization thereon of crosslinked polythylene glycols (called POLYTHERM) to impart several useful properties: thermal storage and release, improved resiliency and resistance to oily soiling, static charge, pilling, wear life, and marked increases in hydrophilicity among them. Moreover, these improved properties were durable because up to 70% of the crosslinked polyol was retained after 50 launderings. Such modification was achieved by using average molecular weights of the polyols ranging from 600 to 20,000 by crosslinking with polyfunctional methylolamides (such as DMDHEU) in the presence of acid catalysts by a conventional pad‐dry‐cure textile finishing procedure. The role of crosslink density of the polyol in determining textile properties was determined by evaluation of films derived from crosslinking the polyols and comparison of selected properties.
Reactive powder concrete bridges (2006)

Reactive powder concrete (RPC) is a cementitious material consisting of cement, sand, silica fume, silica flour, admixture and water. Ductal (registered trade name) is an RPC that contains large quantities of steel or organic fibres. The properties of Ductal are unique, and allow designers to create innovative bridge structures of value that are both structurally efficient and provide excellent resistance to aggressive agents. Around the world, many examples of innovative RPC bridges exist. They include the world's first RPC pedestrian bridge, Sherbrooke Footbridge in Quebec, Canada; the 120m span Sunyudu Footbridge in Seoul, Korea; Sakata-Mirai Footbridge in Japan, and more recent highway bridges in Virginia and Iowa, USA. In Australia, the world's first road bridge built using Ductal was completed in October 2004 at Shepherds Creek. This project was used as an evaluation of the material by the Roads and Traffic Authority (RTA), New South Wales. This paper provides a summary of the properties of Ductal, design considerations, and primarily gives examples of reactive powder bridges around the world.

Millivolt Modulation of Plasmonic Metasurface Optical Response via Ionic Conductance (2017)

A plasmonic metasurface with an electrically tunable optical response that operates at strikingly low modulation voltages is experimentally demonstrated. The fabricated metasurface shows up to 30% relative change in reflectance in the visible spectral range upon application of 5 mV and 78% absolute change in reflectance upon application of 100 mV of bias. The designed metasurface consists of nanostructured silver and indium tin oxide (ITO) electrodes which are separated by 5 nm thick alumina. The millivolt-scale optical modulation is attributed to a new modulation mechanism, in which transport of silver ions through alumina dielectric leads to bias-induced nucleation and growth of silver nanoparticles in the ITO counter-electrode, altering the optical extinction response. This transport mechanism, which occurs at applied electric fields of 1 mV nm<sup>-1</sup> , provides a new approach to use of ionic transport for electrical control over light-matter interactions.
Accurate millisecond timing on Apple’s Macintosh using Drexel’s MilliTimer (1986)

Many of the timed functions that concern psychologists, such as perceptual presentations and reaction time, are sensitive to a maximum variability in display timing caused by screen-refresh characteristics. For the Apple Macintosh, the screen operating speed is 60 Hz, which translates to an average of 8.33-msec variability. For microcomputers other than the Macintosh, a variety of hardware and software modifications to generate millisecond timing have become standard (e.g., Reed, 1979). Other than Reed College’s (1985) implementation in Rascal, which requires the Rascal development language, there has been no method of which we were aware to synchronize experimental timing with display presentation on the Macintosh. This limitation in the usefulness of the Macintosh as an otherwise excellent research tool can be overcome using Drexel University’s MilliTimer. The assembler code which follows should be considered in the public domain and can be readily adapted to any of the Macintosh-based languages.
Improving Solid‐Supported Catalyst Productivity by Using Simplified Packed‐Bed Microreactors (2007)

Going with the flow: Packed-bed microreactors are formed from polymeric tubing and a resin-supported catalyst. By using supported catalysts in flow systems, productivity and recycling are greatly improved. This approach can be used to couple multiple catalysts together for generating complex molecules in one flow-through process.
