Ordered porous diamond films fabricated by colloidal crystal templating (2011)

We have developed a colloidal crystal templating method for preparation of diamond films with 2D and 3D ordered porous structures. The technological process involved breaks down into (a) impregnation into the pores of silica colloidal crystal (opal) films of detonation nanodiamond (DND) particles from their hydrosol; (b) microwave plasma-enhanced chemical vapor deposition (MWPECVD) regrowth with diamond of pores with high DND filling; (c) Ar(+) ion dry etching of fragments of shells of coalesced diamond crystallites which form in the course of MWPECVD on the surface of the SiO(2) beads making up the outer surface of a film and (d) wet etching of the SiO(2) template in aqueous HF solution. The final samples are either connected to the substrate or free-standing films of various thicknesses having 2D or 3D ordered porous structures. The morphology of the diamond films fabricated by this method replicates the pore network of the opal template. Raman measurements confirm the diamond structure of the synthesized ordered porous material.

The Synchronous Instability of a Compressor Rotor due to Bearing Journal Differential Heating (1994)

The paper describes a synchronous vibration instability problem encountered on a centrifugal compressor with oil lubricated bearings. The problem was solved by modification of the compressor rotor, however the root cause was not completely understood at that time. A possible explanation was based on a theory which suggested differential heating of the bearing journals. It was decided to verify ibis theory by experiments. Therefore a test rotor was designed with identical rotor dynamic characteristics to those of the compressor rotor. In order to fill a gap in the published research on bearing thermohydrodynamics an experimental technique was devised to measure the surface temperature variations around one of the journals of this rotor. The dependence of significant temperature differentials across the journal upon its orbit was confirmed.

A Nonlinearity-Calibration-Free Reconfigurable ADPLL for General Purpose Frequency Modulation (2020)

This paper presents an all-digital PLL (ADPLL) based two-point modulator reconfigurable for wideband or narrowband FM with optimum performance. In either case, the proposed modulator does not perform background digital calibration to overcome the nonlinearity of key building blocks such as a TDC, a DTC, and a DCO, while requiring only initial calibration for process variation and frequency pre-tuning over different channels. For the narrowband FM, the proposed modulator works as a 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> -point modulator where a high-pass modulation pass is performed with FIR-filtered 1b DCO modulation. In the case of the wideband FM, a nested ADPLL is designed to realize an absolute-gain DCO within the two-point modulator. To suppress quantization noise from a ΔΣ modulated divider, a high-frequency 4/5 divider is directly modulated. A 3b DTC between the 4/5 divider and an integer divider also works as an antialiasing filter for low in-band phase noise. Simulation results show that the proposed modulator can perform not only 1Mb/s GFSK modulation with the modulation index of 0.5 but also SSCG or FMCW modulation with very high modulation index, achieving good modulation linearity without nonlinearity calibration.
Gain-Assisted Surface Plasmon Resonance Refractive Index Sensor (2017)

Surface plasmon resonance (SPR) has been a topic of intense research in refractive index sensors due to the benefits of high resolution, high sensitive, real-time, and label-free technology. But losses restrict the operational parameters of SPR-based devices. In this paper, a new design of SPR sensor structures using gain medium are proposed. These novel prisms-based structures are based on Otto and Kretschmann configurations. Regard to gain coefficient of an active layer, two different regimes have been introduced in which loss compensating and amplifying surface plasmons polaritons are occurred. The effect of geometrical parameters on SNR enhancement factor is investigated theoretically and finally, the optimum layers' thicknesses for the fixed values of gain coefficient and wavelength will be examined. Signal-to-noise ratio in the proposed structures could be enhanced by a factor of two orders of magnitudes.
A wavelike origin for clumpy structure and broad line wings in molecular clouds (1990)

The strong magnetosonic waves that are likely to be generated by virialized motions in molecular clouds should steepen into shocks and density irregularities that may be identified with some of the fine-scale or clumpy structure in these clouds. This process is illustrated here with a numerical solution to the magnetosonic equations with diffusion, in the case of two colliding, linearly polarized wavetrains. The parallel and perpendicular velocities that are associated with such clumps are comparable to the local Alfven speed. This implies that the broad wings in non-Gaussian line profiles (unassociated with embedded stars) could be the result of wave-related motions in the low-density regions of molecular clouds. Theoretical composite line profiles derived for a line of sight containing density substructures of the form n proportional to r exp -alpha and Alfven velocity variations of the form vA proportional to n exp -beta fit the observed core-wing molecular line profiles for reasonable alpha and beta.
Web Services for Negotiation and Bargaining in Electronic Markets: Design Requirements and Implementation Framework (2005)

Information systems researchers continue to develop Web services hoping that, in a near future, these services will be offered in the e-marketplace. Perhaps the most foreseeable mechanism to enable the web services market is the use of WSDL, SOAP, XML, UDDI and the like that allow posting of existing services. Posting services does not, however, necessarily lead to market transactions. In this paper, we propose a set of web services that provide negotiation and bargaining support to facilitate the matching of supply and demand of web services. As a market broker, these web services would help (a) discover the supply/demand of web services; (b) find the most appropriate available service for a given request; (c) request services be modified if needed to satisfy user’s needs; (d) arbitrate the pricing mechanism with the recourse to bargaining whenever necessary; and (e) generate a contract.
Point process modeling reveals anatomical non-uniform distribution across the Subthalamic Nucleus in Parkinson's disease (2012)

Deep brain stimulation (DBS) is a highly promising therapy for Parkinson's disease (PD). However, most patients do not get full therapeutic benefit from DBS, due to its critical dependence on electrode location in the Subthalamic Nucleus (STN). For this reason, we believe that the development of a novel surgical tool for DBS placement, i.e., an automated intraoperative closed-loop DBS localization system, is essential. In this paper, we analyze single unit spiking activity of 120 neurons in different STN locations collected from 4 PD patients. Specifically, for each neuron, we estimate a point process model (PPM) of the spiking activity for different depths within the STN by which we are able to detect pathological bursting and oscillations. Our results suggest that these signatures are more prominent in the dorsolateral part of the STN. Therefore, accurately placing the DBS electrode in this target may result in maximal therapeutic benefit with less power effort required by DBS. Furthermore, PPMs might be an effective tool for modeling of the STN neuronal activities as a function of location within the STN, which may pave the way towards developing a closed-loop navigation tool for optimal DBS electrode placement.
Treatment of Periprosthetic Osteolysis Using Trabecular Metal in Revision Knee Arthroplasty (2012)

Introduction Several options exist for the treatment of periprosthetic osteolysis in revision knee surgery. We describe our preliminary short-term experiences using trabecular metal (TM) technology in order to fill bony defects either on the femoral or on the tibial side. Material and Methods 52 revision knee surgeries in which this TM technology had been used were retrospectively reviewed clinically and radiographically. Indication for revision included 51 cases with aseptic loosening of Total Knee Arthroplasty. In one case of periprostheti infection, a staged revision procedure was performed. Assessment of bone loss included the AORI classification (1989) and was performed pre- and intraoperatively. Clinical evaluation was performed using the HSS score. In 6 cases in addition to usng the TM cones, an impaction grafting technique was performed. Results Average follow up was 22 months. So far, not loosening of a TM cone neither clinically nor radiographically was observed. In 74% of the cases, either a type FII-TII-FIII or TIII defect was seen. Average number of pre-existing surgeries was 4,6. Pre-operative Range of motion was 0-84 degrees and 0-98 degrees at time of latest follow up. Complications in this series included 2 periprosthetic fractures and 1 periprosthetic infection, later revised to a successful fusion. Upon explantation of the TM cone in this case, stable osteointegration was observed. HSS score increased from 34 to 62 points postoperatively (49-93). Discussion Treatment of severe periprosthetic osteolysis in our eyes can be managed successfully in the short-term range using TM technology which requires a meticulous surgical technique and proper indication. This material might be successfully combined using homologous bone as an adjunct.
Transdermal Patch of Rotigotine Attenuates Freezing of Gait in Patients with Parkinson's Disease: An Open-Label Comparative Study of Three Non-Ergot Dopamine Receptor Agonists (2016)

Objective Parkinson's disease (PD) is characterized by the progressive degeneration of the nigrostriatal dopaminergic neurons. Rotigotine is a non-ergot dopamine receptor agonist (DA). Its transdermal patch maintains the effective concentrations for 24 hours. Freezing of gait (FOG) is a common and devastating symptom in PD patients. Little is known about therapeutic effects of rotigotine on FOG in PD patients. Herein we compared how three non-ergot DAs of rotigotine, pramipexole LA and ropinirole CR influence FOG, besides classical motor deficits in PD patients. Methods Rotigotine (maintenance doses of 9-27 mg/day) was administered in 51 patients, 36 patients received pramipexole LA (1.5-4.5 mg/day) and 35 patients received ropinirole CR (8-16 mg/day). The Unified PD Rating Scale (UPDRS) parts I-IV, FOG questionnaire (16 items) and wearing off time were examined from baseline to 7 months after DA administration. UPDRS parts I-IV were evaluated during on time and FOG was recorded during off time if patients experienced wearing off. Results A total of 111 patients completed the study. UPDRS parts II-III scores and wearing off time were significantly reduced after each DA treatment compared to baseline. FOG was found in 54 patients (49%). Most patients developed FOG during off time only. FOG scores were significantly decreased at 2 months after rotigotine treatment whereas pramipexole LA and ropinirole treatment did not alter FOG scores. Conclusion The present study indicates that transdermal patch of rotigotine attenuated the FOG off time. The similar binding affinities to dopamine receptors between rotigotine and dopamine, and 24 hours steady hemodynamics could contribute to the therapeutic mechanism of rotigotine on FOG in PD patients with wearing off.

Self-consistent generator coordinate method (1976)

An optimum continuous representation technique derived in analogy with the self-consistent harmonic approximation in quantum lattice dynamics is discussed and applied to Lipkin's model. The method is based on the variational principle and corresponds to an infinite summation of an expansion of the appropriate Hamiltonian kernel. The overlap kernel is treated exactly. The actual results indicate the removal of the drawbacks of low order perturbation theory previously employed in this connection.NUCLEAR STRUCTURE Continuous representation method applied to a solvable model.
Numerical Simulation of Time-Dependent Flow Behind a Pair of Active Vortex Generators (2005)

This paper is focused on numerical simulation of subsonic flow behind a pair of active vortex generators (AVG) over a flat plate. The active vortex generator consists of a pair of deployable circular wing lip type blades driven by a particular duty cycle. In the present numerical simulation, the three-dimensional Navier-Stokes equations for compressible flow are solved using a fully implicit LU-SGS method. The immersed boundary method is used to model the motion of the active vortex generator. A fourth-order finite difference scheme is used to compute the spatial derivatives. The non-reflecting boundary conditions are imposed at the far-field, inlet, and outlet boundaries to avoid the possible reflection of non-physical wave into the computational domain. The evolution of the longitudinal vortices downstream of the vortex generator, as predicted by the simulation, is comparable to the results of a similar experiment.
Real Time Low-level Pedestrian Detection on a Moving Car (2007)

This paper presents a real-time pedestrian candidates detection algorithm, which is capable of handling the challenges of stationary as well as moving objects, utilizing a single car mounted monochrome camera. First, the system detects obstacles above the ground plane by utilizing the inverse perspective mapping (IPM) algorithm. A fast digital image stabilization algorithm is used to compensate the oscillation of the camera on the vehicle. Afterward, a low level pedestrian segmentation algorithm is developed to extract bounding boxes of potential pedestrians. Finally, robust symmetry search and symmetry filtering algorithms are applied to align the detection result to the pedestrian. Further more a novel Pedestrian Detection Strip (PDS) is introduced to reduce the calculation time by factor of six. The performance test methodology and experimental results are also provided.

Butea monosperma seed extract mediated biosynthesis of ZnO NPs and their antibacterial, antibiofilm and anti-quorum sensing potentialities (2021)

Nanoparticles (NPs) prepared through safer, eco-friendly and natural-based products can be used various applications including antimicrobial and biomedical applications. Quorum sensing (QS) is a complex system for intercellular communication that regulates the expression of many virulence determinants, in the opportunistic Pseudomonas aeruginosa. Thus, the disruption of QS-mediated communication system could be an alternative strategy to combat infection caused by drug resistant P. aeruginosa. In this study, zinc oxide nanoparticles (ZnO NPs) were synthesized by using seed extract of Butea monosperma and further characterized by XRD, SEM and TEM. The biosynthesized ZnO NPs were then subjected to the investigation of their antibacterial, antibiofilm activities as well as the anti-quorum sensing potentialities for biomedical applications. The minimum inhibitory concentration (MIC) value against P. aeruginosa was found 1600 µg/ml, and it was found that ZnO NPs effectively reduced virulence factors Viz. swarming and swimming of P. aeruginosa by 62.8 and 45%, respectively. Exopolysaccharides production was also affected by ZnO NPs which indicate the disruption of biofilm formation. Further, the in silico docking analysis displayed that ZnO NPs efficiently interacted within QS (Las/Rhl) mechanism of P. aeruginosa by binding to the catalytic cleft of LasI synthase (Gly-116-ZnO = 2.8 Å), RhlI synthase (Gly-180-ZnO = 3.7 Å) and transcription receptor protein LasR receptor (Asn-141-ZnO = 2.9 Å), RhlR receptor (Tyr-72-ZnO = 2.6 Å). Thus, it was concluded that the effective interaction of ZnO NPs with Las and Rhl system led to the inactivation of autoinducers such as N-acyl homoserine lactones (AHL) molecules which finally led to the inactivation of QS and down regulation of virulence determinants. Consequently, the present in vitro and in silico results obtained suggest that the synthesized ZnO NPs can be efficiently used as potent antimicrobial agents to prevent the colonization, biofilm formation as well as anti-QS-mediated determinants caused by pathogenic drug resistant bacteria.

As a case study, the method was used to characterize the energy level of the atomic oxygen produced by the Canadian Space Agency’s Space Simulation Apparatus (SSA), the value of which is determined to be 0.063 eV.
Continuous Measurement of Bulk Density of Frost Layer by Spectral Bi-Angular Reflectance Method (1994)

Continuous measurements by the spectral bi-angular reflection method are carried out for frost layer growing at the atmospheric pressure and the room temperature in the surrounding atmosphere. A four-flux model of radiation transfer is introduced to analyze the measured data. The spectral absorption and scattering coefficients are evaluated in connection with the bulk density of frost layer; The absorption coefficients at the absorption band of ice prove to be proportional to the bulk density of frost layer. The results of the optical measurements show the necessity to consider the stratified structure of frost layer in the 'crystal growth period'.
