Fine Resolution Air Quality Monitoring from a Small Satellite: CHRIS/PROBA (2008)

Current remote sensing techniques fail to address the task of air quality monitoring over complex regions where multiple pollution sources produce high spatial variability. This is due to a lack of suitable satellite-sensor combinations and appropriate aerosol optical thickness (AOT) retrieval algorithms. The new generation of small satellites, with their lower costs and greater flexibility has the potential to address this problem, with customised platform-sensor combinations dedicated to monitoring single complex regions or mega-cities. This paper demonstrates the ability of the European Space Agency's small satellite sensor CHRIS/PROBA to provide reliable AOT estimates at a spatially detailed level over Hong Kong, using a modified version of the dense dark vegetation (DDV) algorithm devised for MODIS. Since CHRIS has no middle-IR band such as the MODIS 2,100 nm band which is transparent to fine aerosols, the longest waveband of CHRIS, the 1,019 nm band was used to approximate surface reflectance, by the subtraction of an offset derived from synchronous field reflectance spectra. Aerosol reflectance in the blue and red bands was then obtained from the strong empirical relationship observed between the CHRIS 1,019 nm, and the blue and red bands respectively. AOT retrievals for three different dates were shown to be reliable, when compared with AERONET and Microtops II sunphotometers, and a Lidar, as well as air quality data at ground stations. The AOT images exhibited considerable spatial variability over the 11 x 11km image area and were able to indicate both local and long distance sources.
Placental Expression of miR-517a/b and miR-517c Contributes to Trophoblast Dysfunction and Preeclampsia (2015)

Preeclampsia is a pregnancy specific hypertensive disease that confers significant maternal and fetal risks. While the exact pathophysiology of preeclampsia is unknown, it is widely accepted that placental dysfunction is mechanistically involved. Recent studies reported aberrant expression of placenta-specific microRNAs (miRNAs) in preeclampsia including miR-517a/b and miR-517c. Using placental biopsies from a preeclampsia case-control study, we found increased expression of miR-517a/b in term and preterm preeclampsia vs controls, while, miR-517c was increased only in preterm preeclampsia vs controls. To determine if miR-517a/b and miR-517c are regulated by hypoxia, we treated first trimester primary extravillous trophoblast cells (EVTs) with a hypoxia mimetic and found both were induced. To test for a mechanistic role in placental function, we overexpressed miR-517a/b or miR-517c in EVTs which resulted in decreased trophoblast invasion. Additionally, we found that miR-517a/b and miR-517c overexpression increased expression of the anti-angiogenic protein, sFLT1. The regulation of sFLT1 is mostly unknown, however, TNFSF15, a cytokine involved in FLT1 splicing, was also increased by miR-517a/b and miR-517c in EVTs. In summary, we demonstrate that miR-517a/b and miR-517c contribute to the development of preeclampsia and suggest that these miRNAs play a critical role in regulating trophoblast and placental function.
Multi-feed NVIS realization on small aircraft using characteristic modes (2015)

Characteristic modes (CMs) are used to design an NVIS antenna system on-board an electrically small UAV. Using the CMs of the UAV platform, near-vertical incident skywave (NVIS) are realized using pre-specified locations for antenna mounting. The appropriate excitation level of each monopole feed can be computed in a systematic manner using the CMs of the composite UAV + monopole antenna system. Discussions on pattern and bandwidth of this approach as a function of feeding element number will be presented, as well as discussions on further optimization approaches that can be effectively utilized from a characteristic modes perspective.

An adaptive senior design course with an emphasis on undergraduate course curriculum (2017)

The senior design course is a typical indicator of the success and productivity of the undergraduate course curriculum. Senior design course bridges the gap between the theoretical and practical domain along with providing hands on experience. Hence, it is crucial to have a concrete and highly productive course structure. This paper provides a quantitative evaluation of the outcomes i) to determine the merit of the curriculum and ii) to offer a crucial assessment of student competencies. Accordingly, this paper discusses a framework of the senior design course at the University of South Florida and the iterative work it underwent over the span of three semesters resulting in a significant improvement in the students' performance. This study focuses on a database of the undergraduate students from the last three semesters and underlines the facilitation of assessing an undergraduate course curriculum through a senior design project.

We also\npropose practical implementations.
Interrogation of 2,2′-Bipyrimidines as Low-Potential Two-Electron Electrolytes (2021)

As utilization of renewable energy sources continues to expand, the need for new grid energy storage technologies such as redox flow batteries (RFBs) will be vital. Ultimately, the energy density of a RFB will be dependent on the redox potentials of the respective electrolytes, their solubility, and the number of electrons stored per molecule. With prior literature reports demonstrating the propensity of nitrogen-containing heterocycles to undergo multielectron reduction at low potentials, we focused on the development of a novel electrolyte scaffold based upon a 2,2'-bipyrimidine skeleton. This scaffold is capable of storing two electrons per molecule while also exhibiting a low (∼-2.0 V vs Fc/Fc<sup>+</sup>) reduction potential. A library of 24 potential bipyrimidine anolytes were synthesized and systematically evaluated to unveil structure-function relationships through computational evaluation. Through analysis of these relationships, it was unveiled that steric interactions disrupting the planarity of the system in the reduced state could be responsible for higher levels of degradation in certain anolytes. The major decomposition pathway was ultimately determined to be protonation of the dianion by solvent, which could be reversed by electrochemical or chemical oxidation. To validate the hypothesis of strain-induced decomposition, two new electrolytes with minimal steric encumbrance were synthesized, evaluated, and found to indeed exhibit higher stability than their sterically hindered counterparts.
Discrimination of Timbre in Early Auditory Responses of the Human Brain (2011)

Our results demonstrate that the auditory response depends on timbre characteristics. Moreover, it was revealed that the auditory sensory gating is determined not by the stimulus that directly evokes the response, but rather by whether or not the two stimuli are identical in timbre.
HELICAL SURFACE WAVES ON A DIELECTRIC ROD (1986)

Abstract The conventional formulation of the electromagnetic field solution for a cylindrical dielectric rod is re-interpreted in a novel fashion in order to show the presence of surface waves which propagate over the rod's surface along helical paths. The solutions of the characteristic equation of the rod are interpreted in terms of the resonances at which these helical surface waves azimuthally match phases after each circumnavigation of the rod, effectively forming resonating standing waves around the rod. This interpretation permits us to obtain the pitch angle of the helix, and the dispersion curves (phase velocity as a function of frequency) of the helical surface waves.
Cost-based media server design (2002)

Conventional wisdom holds that reducing disk latency leads to higher disk utilization, maximizing disk utilization leads to higher throughput, and employing a faster disk leads to better performance. All of this is true when building a conventional file or database system. We show that these principles can be misleading when applied to a media server. To design such a server, we propose a cost-based approach that focuses on the per-stream costs. We give various examples to illustrate the design process.
Impurity-Driven Anode Surface Chemistry in Organic Electrolytes for Multivalent Ion Batteries (2017)

One the biggest challenges facing the development of Mg-ion battery technology is the fact that many promising Mg electrolytes are incompatible with either the metallic Mg anode or with the high voltage oxide cathode materials that are required to compete with existing Li-ion technologies. Understanding the role of the many impurity species present in Mg electrolytes is crucial to understanding how to design new electrolytes that can stabilize Mg metal without using Cl - , and therefore enable its use with oxide cathodes in full cells. In light of these complexities, we introduce a surface science-based approach for rationalizing, and ultimately understanding, the impurity-driven electrochemical processes that take place during the electrodeposition of Mg ions, focusing in particular on the technologically-relevant Mg bis-(trifluoromethane sulfonyl) imide (MgTFSI 2 ) in diglyme electrolyte system. Using a combination of electrochemical and spectroscopic methods, it was found that trace amounts of water (≤ 3 ppm) strongly impact both the kinetics of Mg deposition and the reversibility of Mg stripping, with the formation of passive surface films taking place only after Mg deposition ceases and the extent of passivation determining the electrochemical response and resulting Coulombic efficiency. A complex and dynamic competition between H 2 O and Cl - species present at the interface was also observed that results in dramatic changes to the surface chemistry and the resulting deposition/stripping kinetics. We anticipate that this surface science-based approach is relevant well beyond Mg deposition/stripping, and can be applied to the deposition/stripping of Li and other mono/multivalent metals, intercalation/deintercalation processes in multivalent cathode materials, and many other systems.
Application of Electrostatic Precipitator to the Gasoline Engine (1977)

In order to control air pollution in automobile exhaust particulates, the authors applied the electrostatic precipitator (E. P.) to the gasoline engine. The trial E. P. have two features to be mounted on the automobiles. The first point is the compact design of E. P. The other point is high voltage power source was supplied from car's battery by a method of using the trial DC-AC invertor. In this study two kinds of engines have been used; one is 4 cycle engine, Nissan Prince 1500cc, and the other is 2 cycle engine, Suzuki Fronte 360cc. The test was perfomed under no load driving.The results are summarized as follow:1) Collection efficiency was rather satisfactory.2) Particle size distribution of 4 cycle engine exhaust showed to obey log-normal distribution. and it's particle size was mostly to be so much smaller than 1μm diameter.3) About 35 percent of lead supply in fuel were emitted under our condition. The remainder were accumulated in the engine and exhaust system as deposit.E. P. is available in air pollution control. We have the dawn of hope for applying the E. P. to the gasoline engine.
The development of mini pentameric STR loci for rapid analysis of forensic DNA samples on a microfluidic system (2010)

There is increasing interest in developing methods for portable DNA analysis in mass disasters and criminal identification. Currently most forensic STR DNA analysis is performed by CE; however, these instruments are not portable and require long sample run times. One potential solution is the development of microfluidic systems for DNA typing. Unfortunately, fairly long (ca. 20 cm) separation channels are usually required for the proper resolution of multiplexed STR loci used in human identification. Commercially available systems like the Agilent 2100 Bioanalyzer have a small footprint and utilize chips with shorter channels and reduced resolution. Such portable systems might be valuable for evidence screening in remote locations. However, due to their lower resolution, most standard 4 base STR loci and their inherent 2 base variants will not resolve on such systems. In this paper, we discuss the development of reduced length pentameric (5 base) STR amplicons. Pentameric STRs have fewer variant alleles and are easier to separate due to the wider spacing between alleles. By incorporating novel denaturing sieving polymers in a short microfluidic channel, we demonstrate efficient separations on these chips. Such an approach can serve as a useful tool for rapid microfluidic DNA typing.
(Phosphinyloxy)acyl amino acid inhibitors of angiotensin converting enzyme. 2. Terminal amino acid analogs of (S)-1-[6-amino-2-[[hydroxy(4-phenylbutyl)phosphinyl]oxy]-1-oxohexyl]-L-proline (1990)

Analogues of (S)-1-[6-amino-2[[hydroxy(4-phenylbutyl)phosphinyl] oxy]-1-oxohexyl]-L-proline (1, SQ 29,852) in which the terminal proline residue has been replaced by a variety of substituted and heteroatom-substituted prolines, N-arylglycines, N-cycloalkylglycines, and bicyclic amino acids have been synthesized and evaluated as inhibitors of angiotensin converting enzyme in vitro and in vivo. In general, the addition of lipophilic substituents to the 4-position of proline of the parent phosphonate 1 resulted in substantial increases in in vitro activity. The largest improvements were observed in the case of cis-benzyl (36-fold) and dithioketal (24-fold) analogues 2r and 2x, respectively. These enhancements of in vitro activity were accompanied by modest increases (2-3.5-fold) in in vivo (iv) activity. Among the various terminal amino acid replacements examined in this study, the indoline-based analogue 2i was by far the most potent compound on iv administration in the normotensive rat.

A new initial‐rotor‐position estimation method for SPM synchronous motors using spatially rotating high‐frequency voltage: A dynamic simulator approach taking flux saturation phenomena into account (2007)

Abstract First, this paper proposes a new dynamic mathematical model of surface‐mounted permanent magnet synchronous motors (SPMSMs) with flux saturation phenomena, in a stationary reference frame. Second, based on the dynamic model, this paper establishes new dynamic simulators taking flux saturation phenomena into account, which act as very powerful tools for developing initial‐rotor‐position estimation methods for SPMSMs. Third, this paper proposes a new initial‐rotor‐position estimation method for SPMSMs. The proposed method is so simple that it inputs a spatially rotating high‐frequency voltage to SPMSMs, measures current output, and can estimate directly rotor position of N‐pole through norm evaluation of the current. The method exploits flux saturation phenomena inherent to SPMSMs and is insensitive to all motor parameters. According to experiments, the maximum estimation error is about ±0.035 rad (±2 ○ ) in terms of mechanical angle, which is comparable to sensor mounting error and is sufficiently small for initial drive of SPMSMs. © 2007 Wiley Periodicals, Inc.

PSTR: End-to-End One-Step Person Search With Transformers (2022)

We propose a novel one-step transformer-based person search framework, PSTR, that jointly performs person detection and re-identification (re-id) in a single architecture. PSTR comprises a person search-specialized (PSS) module that contains a detection encoder-decoder for person detection along with a discriminative re-id decoder for person re-id. The discriminative re-id decoder utilizes a multi-level supervision scheme with a shared decoder for discriminative re-id feature learning and also comprises a part attention block to encode relationship between different parts of a person. We further introduce a simple multi-scale scheme to support re-id across person instances at different scales. PSTR jointly achieves the diverse objectives of object-level recognition (detection) and instance-level matching (re-id). To the best of our knowledge, we are the first to propose an end-to-end one-step transformer-based person search framework. Experiments are performed on two popular benchmarks: CUHK-SYSU and PRW. Our extensive ablations reveal the merits of the proposed contributions. Further, the proposed PSTR sets a new state-of-the-art on both benchmarks. On the challenging PRW benchmark, PSTR achieves a mean average precision (mAP) score of 56.5%. The source code is available at https://github.com/JialeCao001/PSTR.
Robust designs through partially clear two-factor interactions (2011)

Orthogonal arrays with clear two-factor interactions provide a class of designs that are robust to nonnegligible effects. If certain prior knowledge is available, then robust designs allow additional factors to be studied. This is done through partially clear two-factor interactions. We study the existence and construction of such robust designs and present an upper bound on the maximum number of clear two-factor interactions.
mDixon-Based Synthetic CT Generation for PET Attenuation Correction on Abdomen and Pelvis Jointly Using Transfer Fuzzy Clustering and Active Learning-Based Classification (2019)

We propose a new method for generating synthetic CT images from modified Dixon (mDixon) MR data. The synthetic CT is used for attenuation correction (AC) when reconstructing PET data on abdomen and pelvis. While MR does not intrinsically contain any information about photon attenuation, AC is needed in PET/MR systems in order to be quantitatively accurate and to meet qualification standards required for use in many multi-center trials. Existing MR-based synthetic CT generation methods either use advanced MR sequences that have long acquisition time and limited clinical availability or use matching of the MR images from a newly scanned subject to images in a library of MR-CT pairs which has difficulty in accounting for the diversity of human anatomy especially in patients that have pathologies. To address these deficiencies, we present a five-phase interlinked method that uses mDixon MR acquisition and advanced machine learning methods for synthetic CT generation. Both transfer fuzzy clustering and active learning-based classification (TFC-ALC) are used. The significance of our efforts is fourfold: 1) TFC-ALC is capable of better synthetic CT generation than methods currently in use on the challenging abdomen using only common Dixon-based scanning. 2) TFC partitions MR voxels initially into the four groups regarding fat, bone, air, and soft tissue via transfer learning; ALC can learn insightful classifiers, using as few but informative labeled examples as possible to precisely distinguish bone, air, and soft tissue. Combining them, the TFC-ALC method successfully overcomes the inherent imperfection and potential uncertainty regarding the co-registration between CT and MR images. 3) Compared with existing methods, TFC-ALC features not only preferable synthetic CT generation but also improved parameter robustness, which facilitates its clinical practicability. Applying the proposed approach on mDixon-MR data from ten subjects, the average score of the mean absolute prediction deviation (MAPD) was 89.78±8.76 which is significantly better than the 133.17±9.67 obtained using the all-water (AW) method (p=4.11E-9) and the 104.97±10.03 obtained using the four-cluster-partitioning (FCP, i.e., external-air, internal-air, fat, and soft tissue) method (p=0.002). 4) Experiments in the PET SUV errors of these approaches show that TFC-ALC achieves the highest SUV accuracy and can generally reduce the SUV errors to 5% or less. These experimental results distinctively demonstrate the effectiveness of our proposed TFCALC method for the synthetic CT generation on abdomen and pelvis using only the commonly-available Dixon pulse sequence.
The Performance of <font>Hg</font><sub>0.8</sub><font>Cd</font><sub>0.2</sub><font>Te</font> Photodetectors by Using Photo Surface Treatment (1997)

The principal aim of this paper is to propose an easy, vapor phase, and reproducible photo surface treatment method to improve the device performance of the Hg 0.8 Cd 0.2 Te photoconductive detector. Experimental results, including Auger electron spectroscopy (AES), MIS leakage current, 1/f noise voltage spectrum, 1/fknee frequency, responsivity R λ , and specific detectivity D* for stacked photo surface treatment and ZnS or CdTe passivation layers are presented. By using this method, we found that there is no accumulation of Hg in the oxide/HgCdTe interface regions. Since the photo chemical vapor native oxidation is a dry oxidation method deposited at a low temperature, it can effectively suppress the Hg enhancement and the Cd depletion effects and thus obtain a high quality interface. We also found that the photo surface treatment in combination with thermally eveporated ZnS or CdTe layer would shift the 1/fknee under 100Hz in an electrical field under 50 V/cm, reduce the noise power spectrum, and achieve a lower surface recombination velocity S of 300 cm/sec as well as a high D* of 3 × 10 10 cm [Formula: see text] for blackbody radiation. It was also found that HgCdTe photoconductor passivated with stacked layers shows improved interface properties when compared to the photoconductor passivated with a single passivation layer.
Holographic grating for dense wavelength division optical filters at 1550 nm using phenanthrenquinone-doped poly(methyl methacrylate) (2003)

The characteristics of Phenanthrenquinone (PQ) doped Polymethyl methacrylate (PMMA) for recording edge-illuminated holographic spectral filters for dense wavelength division multiplexing applications are evaluated. Filter design includes the effects of material absorption and apodization of the index profile. Rigorous coupled wave theory and transfer matrix methods are used to simulate the performance of the filters for dense wavelength division multiplexing functions. The experimentally measured spectral FWHM bandwidths were 0.20 nm and the primary limitation of the grating performance was found to be residual material absorption.
