Radome enhancing multi-sector antenna radiation performances (2008)

A novel and original concept of relevant radome has been introduced and validated by the design of a foam radome prototype applied to a multi-sector antenna. Metallic elements, directly positioned into the radome, allow to control the antenna radiation pattern. The fact of using radome to support the metallic elements makes it an integral part of the antenna system. Obtained measurements results on a realized 4-sector antenna system with optimized radome patterns showed significant gain improvement and a slight reduction of the cross-polarization level. These interesting results were obtained without modifying the initial antenna dimensions and without significantly degrading the antenna matching in the design frequency band.

EFIE and MFIE, why the difference? (2008)

EFIE (electric field integral equation) suffers from internal resonance, and the remedy is to use MFIE (magnetic field integral equation) to come up with a CFIE (combined field integral equation) to remove the internal resonance problem. However, MFIE is fundamentally a very different integral equation from EFIE. Many questions have been raised about the differences.

Demo (2012)

We present a demo of Odin, an SDN framework to program enterprise wireless local area networks (WLANs). Enterprise WLANs need to support a wide range of services and functionalities. This includes authentication, authorization and accounting, policy, mobility and interference management, and load balancing. WLANs also exhibit unique challenges. In particular, access point (AP) association decisions are not made by the infrastructure, but by clients. In addition, the association state machine combined with the broadcast nature of the wireless medium requires keeping track of a large amount of state changes. To this end, Odin builds on a light virtual AP abstraction that greatly simplifies client management. Odin does not require any client side modifications and its design supports WPA2 Enterprise. With Odin, a network operator can implement enterprise WLAN services as network applications.

The Wireless Workhorse: Mixed-Signal Power Amplifiers Leverage Digital and Analog Techniques to Enhance Large-Signal RF Operations (2015)

The ever-growing demand for higher data rates, power efficiency, and robust operations poses increasingly stringent performance requirements on wireless transceiver systems. This is particularly critical for mobile devices in both commercial and defense applications, where improving system size, weight, and power metrics and extending the battery lifetime are often the primary concerns. The power amplifier (PA) serves as the interface between the RF transmitter system and the antenna and is often considered one of the most critical building blocks in a wireless transceiver. This is because the PA's performance has critical impacts on multiple major transmitter metrics, including the output power level, power efficiency, bandwidth, and signal fidelity, and therefore governs the overall quality of service (QoS) of the wireless link [1], [2]. Moreover, due to their large-signal and high-power operations at RF frequencies, PAs often encounter unique design challenges and tradeoffs that deserve special attention [3].
Millet-based intercropping systems facilitated by beneficial microbes for climate-resilient, sustainable farming in tropics (2021)

Climate change is arguably the biggest threat being faced by humankind, one that impacts billions of people through soil erosion, extreme droughts, uneven and unpredictable rains during the cropping season, rises in sea level, etc. Climate-induced droughts limit crop growth and productivity, eventually affecting millions of marginal farmers. Millets are predominantly grown in rainfed and arid regions, especially in the tropical zones of Asia and Africa. They are rich in macro and micronutrients that can complement other sources of nutrition such as cereals, vegetables, fruits, milk, meat and eggs. Millet-based intercropping systems have been practiced in India over centuries. Nevertheless, a sustainable intensification of millet-based intercropping has not yet been achieved. Recent research findings have shown that millet and legume intercropping facilitated by biofertilizers, such as arbuscular mycorrhizal fungi and plant-growth-promoting rhizobacteria, is a promising innovative tool. This chapter aims at exploring research and development perspectives for promoting millet-based intercropping systems for sustainable farming, particularly in the tropics.
Electrochemistry of [(TMpyP)MII]4+(X-)4 (X- = Cl- or BPh4-) and [(TMpyP)MIIICl]4+(Cl-)4 in N,N-Dimethylformamide Where M Is One of 15 Different Metal Ions (2005)

The electrochemistry of 16 different water-soluble porphyrins of the type [(TMpyP)M(II)]4+ (X-)4 or [(TMpyP)M(III)Cl]4+ (Cl-)4 is reported in nonaqueous media where TMpyP is the dianion of meso-tetrakis(N-methylpyridiniumyl)porphyrin and X- = Cl- or BPh4-. These studies were carried out to examine the effect of the metal ion and porphyrin counterion (X-) on the electrochemical properties of the TMpyP complexes with a special emphasis being given to the overall number of electrons added and the number of electrode processes upon reduction. All of the investigated compounds with electroinactive central metal ions undergo an overall addition of six electrons. This occurs for most compounds via three two-electron-transfer steps, but more than three processes are observed for porphyrins having metal ions with a low electronegativity (e.g., Cd(II)). The first reduction of each porphyrin having an M(II) ion or an electroinactive M(III) ion yields a porphyrin dianion which is characterized by an intense band located close to 800 nm, and this reversible reduction is followed by further reductions of the 1-methyl-4-pyridyl groups at more negative potentials. Four of the compounds with electroactive central metal ions, [(TMpyP)M(III)Cl]4+(Cl-)4 (M = Co, Fe, Mn, or Au), undergo an additional reversible M(III)/M(II) process prior to reactions involving the porphyrin pi-ring system and the 1-methyl-4-pyridyl substituents.
Phosphatidylserine receptors enhance SARS-CoV-2 infection (2021)

Phosphatidylserine (PS) receptors enhance infection of many enveloped viruses through virion-associated PS binding that is termed apoptotic mimicry. Here we show that this broadly shared uptake mechanism is utilized by SARS-CoV-2 in cells that express low surface levels of ACE2. Expression of members of the TIM (TIM-1 and TIM-4) and TAM (AXL) families of PS receptors enhance SARS-CoV-2 binding to cells, facilitate internalization of fluorescently-labeled virions and increase ACE2-dependent infection of SARS-CoV-2; however, PS receptors alone did not mediate infection. We were unable to detect direct interactions of the PS receptor AXL with purified SARS-CoV-2 spike, contrary to a previous report. Instead, our studies indicate that the PS receptors interact with PS on the surface of SARS-CoV-2 virions. In support of this, we demonstrate that: 1) significant quantities of PS are located on the outer leaflet of SARS-CoV-2 virions, 2) PS liposomes, but not phosphatidylcholine liposomes, reduced entry of VSV/Spike pseudovirions and 3) an established mutant of TIM-1 which does not bind to PS is unable to facilitate entry of SARS-CoV-2. As AXL is an abundant PS receptor on a number of airway lines, we evaluated small molecule inhibitors of AXL signaling such as bemcentinib for their ability to inhibit SARS-CoV-2 infection. Bemcentinib robustly inhibited virus infection of Vero E6 cells as well as multiple human lung cell lines that expressed AXL. This inhibition correlated well with inhibitors that block endosomal acidification and cathepsin activity, consistent with AXL-mediated uptake of SARS-CoV-2 into the endosomal compartment. We extended our observations to the related betacoronavirus mouse hepatitis virus (MHV), showing that inhibition or ablation of AXL reduces MHV infection of murine cells. In total, our findings provide evidence that PS receptors facilitate infection of the pandemic coronavirus SARS-CoV-2 and suggest that inhibition of the PS receptor AXL has therapeutic potential against SARS-CoV-2.

Microwave Radar Detection of Gas Pipeline Leaks (2003)

We are developing a microwave radar sensing and imaging system to detect and locate gas leaks in natural gas pipelines. The underlying detection principle is radar backscattering from the index‐of‐refraction inhomogeneities introduced by the dispersion of methane in air. An essential first step in the development effort is modeling to estimate the radar cross section. This paper describes the modeling results and the experimental efforts underway to validate the model. For the case of leaks from small holes in a pressurized gas pipeline, we modeled the gas dynamics of the leak jet to determine the plume geometry and the variation of methane concentration in air as a function of distance from the leak source. From the static and dynamic changes in the index of refraction in the turbulent plume, the radar backscatter cross sections were calculated. The results show that the radar cross sections of the leak plumes should be detectable by special‐purpose radars.

Regionalization of engineering (2014)

International project business is often characterized by the fact that the contracting company is working in many countries. The company's strategic intentions and the often-noticed customer requirement to increase local content are the basis for efficiently sharing different elements of the technical value chain between headquarters and organizations in the country where the plant or facility has to be built. In this paper, we describe a process showing how such regionalization efforts can be effectively executed and managed. The process starts with the definition of regionalization goals and an analysis of the company's specific conditions for regionalization. Various scenarios have to be evaluated in order to decide upon the most favorable one. After detailed planning of the regionalization effort, the first regionalized project(s) may be executed. A possible phase-out concludes regionalization if required. In addition to the process, crucial topics are explained in detail in this paper, such as the evaluation of risks inherent to the regionalization effort, the selection of portfolio elements that could be regionalized and cost / benefit considerations. Experience gained in practical regionalization efforts of a big multi-national company is given in order to illustrate the process and topics chosen and to verify the results.

An Adaptive Beam Control Technique for Q Band Satellite to Maximize Diversity Gain and Mitigate Interference to Terrestrial Networks (2016)

The earth observation missions have been improved its sensor performance which results in a huge amount of data to be stored in remote sensing satellite and transmitted to a ground station. Although, satellite to ground transmitter had been usually used X band, several mitigation techniques for rain attenuation have been studied in recent years to migrate to Ka band for broadband transmission. Furthermore, Q band is expected to achieve higher data rate because of its broader bandwidth. However, Q band is shared with terrestrial networks, remote sensing satellite has to take into account potential constrains to them. Therefore, this paper addresses remote sensing satellite network and proposes novel beam control technique to coexist with the terrestrial networks in Q band. The proposed method controls satellite's transmitting antenna boresight adaptively to maximize signal to noise power ratio of satellite ground station and minimize interference to terrestrial networks. The effectiveness of our proposal is verified through simulation results.

Co-Occurrence of Bromine and Iodine Species in US Drinking Water Sources That Can Impact Disinfection Byproduct Formation (2023)

Bromine and iodine species are precursors for forming disinfection byproducts in finished drinking waters. Our study incorporates spatial and temporal data to quantify concentrations of inorganic (bromide (Br<sup>-</sup>), iodide (I<sup>-</sup>), and iodate (IO<sub>3</sub><sup>-</sup>)), organic, and total bromine (Br<sub>T</sub>) and iodine (I<sub>T</sub>) species from 286 drinking water sources and 7 wastewater effluents across the United States. Br<sup>-</sup> ranged from <5-7800 μg/L (median of 62 μg/L in surface water (SW) and 95 μg/L in groundwater (GW)). I<sup>-</sup> was detected in 41% of SW (1-72 μg/L, median = <1 μg/L) and 62% of GW (<1-250 μg/L, median = 3 μg/L) samples. The median Br<sup>-</sup>/I<sup>-</sup> ratio in SW and GW was 22 μg/μg and 16 μg/μg, respectively, in paired samples with detect Br<sup>-</sup> and I<sup>-</sup>. Br<sub>T</sub> existed primarily as Br<sup>-</sup>, while I<sub>T</sub> was present as I<sup>-</sup>, IO<sub>3</sub><sup>-</sup>, and/or total organic iodine (TOI). Inorganic iodine species (I<sup>-</sup> and IO<sub>3</sub><sup>-</sup>) were predominant in GW samples, accounting for 60-100% of I<sub>T</sub>; however, they contributed to only 20-50% of I<sub>T</sub> in SW samples. The unknown fraction of I<sub>T</sub> was attributed to TOI. In lakes, seasonal cycling of I-species was observed and was presumably due to algal productivity. Finally, Spearman Rank Correlation tests revealed a strong correlation between Br<sup>-</sup> and I<sub>T</sub> in SW (<i>R</i><sub>Br<sup>-</sup>,IT</sub> = 0.83) following the log<sub>10</sub> (Br<sup>-</sup>, μg/L) = 0.65 × log<sub>10</sub> (I<sub>T</sub>, μg/L) - 0.17 relationship. Br<sup>-</sup> and I<sup>-</sup> in treated wastewater effluents (median Br<sup>-</sup> = 234 μg/L, median I<sup>-</sup> = 5 μg/L) were higher than drinking water sources.
Cross Rate Synchronization of Loran-C Using the Global Positioning System (1988)

Currently Loran-C transmitters which are in different rate intervals are not tightly synchronized. Consequently, Loran receivers can only compute time differences between stations in the same group rate interval (GRI). In other words, they require at least 2 received signals from each GRI they wish to use. If the receiver can receive many stations, then this limitation is not troublesome. However, if the receiver is near the edge of coverage or if a station has failed, then it can be helpful to remove this limitation and allow the receiver to compute cross rate time differences. The time transfer capability of the Global Positioning System is one way of accomplishing this cross rate synchronization. In this paper 1 we examine (by example) the impact of cross rate synchronization on Loran-C coverage. We do this by developing a Loran accuracy model and considering Loran coverage in the midwest after the midcontinent gap has been filled. We find that cross rate synchronization would be helpful especially if a transmitter has failed. In this paper, we concentrate on the impact of cross chain synchronization on Loran coverage. We give brief consideration to time of transmission control versus system area monitor control, and the combination of Loran and GPS lines of position in user equipment.
Data compression and depth shape reproduction of stereoscopic images (1991)

Abstract Three‐dimensional visual communications, realized with stereoscopic images, can achieve total display realism. To create a three‐dimensional (3‐D) transmission and display system, the large amount of information typically contained in natural images must be reduced and coded by an efficient technique appropriate for stereoscopic images. As the initial step in realizing such a coding scheme, statistical characteristics of stereoscopic images and image characteristics viewed from the aspect of human stereopsis are presented. First, the possibility of data compression that exploits the cross correlation between right and left images is shown. Based on this, a method that shifts one image horizontally and subtracts it from the corresponding area of the other is proposed and evaluated. Next, it is shown that complete depth amplitude reproduction of stereoscopic images through the use of existing CRT display systems is difficult. This is due to the poor horizontal resolution of the forementioned systems even though the depth spatial frequency bandwidth of stereoscopic images can be reduced without deteriorating depth shape reproduction accuracy. Finally, a method for overcoming discontinuous depth reproduction is proposed and its effectiveness is confirmed.
HHV‐8 infection: a model for reactivation and transmission (2002)

The rapid pace of knowledge about HHV-8 since its discovery has been one of the most exciting aspects of medical virology in the last decade. As outlined in this review, the discovery by Drs Chang and Moore of this virus has opened up a broad field of biology with interesting contrasts between current epidemiological data for Kaposi's sarcoma and the cell biology of this gamma herpesvirus. In particular, we summarise the paucity of virological data supporting genital sites of replication and emphasise detection of HHV-8 in the oropharynx. Hopefully continued study will address many of the critical questions that exist today regarding how this infection is transmitted and acquired.
A vaginal drug delivery model (2016)

Efficient drug delivery at vaginal cavity is often a challenge owing to its peculiar physiological variations including vast differences in pH. Keeping in view this attribute of the target site, the current work was aimed at developing formulation strategies which could overcome this and successfully deliver molecules like itraconazole through SLNs. Optimized SLNs with the given composition was selected for further development into mucoadhesive and thermosensitive gel. Stearic acid and Compritol 888 (1:1, w/w ratio) as lipid, a mixture of 3% Poloxomer 188 and 0.5% sodium taurocholate as surfactant and organic to aqueous ratio of 10:50 was taken. Carbopol 934 and Pluronic F 127 were taken for the development of gel. Optimized gel exhibited a desired gelling temperature (35 °C); viscosity (0.920 PaS) and appreciable in vitro drug release (62.2% in 20 h). MTT assay did not show any cytotoxic effect of the gel. When evaluated in vivo, it did not exhibit any irritation potential despite appreciable bioadhesion. A remarkable decrease in CFUs was also observed in comparison with control and marketed formulation when evaluated in rat infection model. Thus, the proposed study defines the challenges for developing a suitable formulation system overcoming the delivery barriers of the vaginal site.
Competition of multiple filaments during the propagation of intense femtosecond laser pulses (2004)

We observed a universal phenomenon of the competition among multiple filaments generated during the propagation of intense femtosecond laser pulses in air. We show that the fluorescence signal from the excitation of nitrogen molecules inside the plasma channel contains important information pertaining to the formation and interaction of multiple filaments. The detected backscattered nitrogen fluorescence from inside the filaments yielded irregular changes from shot to shot which cannot be explained by fluctuation arising from the initial laser pulse itself. Numerical simulations reveal a complex dynamics of multiple filament propagation and interaction dynamics that depends strongly on the initial perturbations of the laser beam. The irregular changes of the fluorescence signal are attributed to the interference between adjacent hot spots that evolve into filaments which give rise to new hot spots (filaments) in between, and thus give the appearance of the fusion or branching of filaments.
