LaMAR: Benchmarking Localization and Mapping for Augmented Reality (2022)

Localization and mapping is the foundational technology for augmented reality (AR) that enables sharing and persistence of digital content in the real world. While significant progress has been made, researchers are still mostly driven by unrealistic benchmarks not representative of real-world AR scenarios. These benchmarks are often based on small-scale datasets with low scene diversity, captured from stationary cameras, and lack other sensor inputs like inertial, radio, or depth data. Furthermore, their ground-truth (GT) accuracy is mostly insufficient to satisfy AR requirements. To close this gap, we introduce LaMAR, a new benchmark with a comprehensive capture and GT pipeline that co-registers realistic trajectories and sensor streams captured by heterogeneous AR devices in large, unconstrained scenes. To establish an accurate GT, our pipeline robustly aligns the trajectories against laser scans in a fully automated manner. As a result, we publish a benchmark dataset of diverse and large-scale scenes recorded with head-mounted and hand-held AR devices. We extend several state-of-the-art methods to take advantage of the AR-specific setup and evaluate them on our benchmark. The results offer new insights on current research and reveal promising avenues for future work in the field of localization and mapping for AR.
Proceedings of the 2nd ACM international conference on Wireless sensor networks and applications (2003)

Welcome to the Second International Workshop on Wireless Sensor Networks and Applications (WSNA 2003), in San Diego, on September 19, 2003. WSNA 2003, sponsored by ACM SIGMOBILE, is held in conjunction with ACM MobiCom 2003 conference. This workshop is a forum for researchers and technologists to present new and innovative research results in wireless sensors, communication protocols, and applications of wireless sensor networks.The workshop is motivated by recent technological advances which have made it possible to design and build large-scale sensor networks containing hundreds to thousands of sensor nodes. Applications envisioned for such networks span several domains including military, environmental, medical, industrial, and smart in-building networks. Some of the key challenges deal with scaling protocols to large number of nodes, and designing energy-conserving protocols and sub-systems as well as appropriate programming and querying languages and information extraction techniques, and developing of exciting new applications that exploit the potential of wireless sensor networks. There are many ongoing research programs to address these challenges at Universities and research laboratories in United States, Europe, and Asia. Most of the funding agencies already have substantial programs and initiatives in this area.We were very pleased with the interest and enthusiasm shown by the research community in this workshop. We received over 60 submissions from across the world. Each paper was reviewed by at least three program committee members, with some assistance from external reviewers. Due to time and space constraints, the workshop could accept only eighteen papers - regrettably, we could not accept several good quality papers. The technical program is organized into five single-track sessions. We take this opportunity to thank the members of the Technical Program Committee and reviewers for their outstanding efforts.The success of this workshop depends on the contributions of many individuals. We would like to thank the workshop General Chairs Cauligi Raghavendra and Krishna Sivalingam for their support in the organizational matters. We also thank David B. Johnson, ACM MobiCom 2003 General Chair, and the ACM SIGMOBILE office members for their encouragement and their timely help. We are greatly indebted to Bhaskar Krishnamachari for doing a superb job with the workshop website and for his efforts in widely publicizing the workshop through various on-line mailing lists and other means. We thank the ACM staff members for their timely help in putting together the proceedings. Finally, on behalf of the Program Committee, we would like to extend our gratitude to the authors, session chairpersons, and the reviewers who contributed to this Workshop.
Cobalt Plasmonic Superstructures Enable Almost 100% Broadband Photon Efficient CO2 Photocatalysis (2020)

The efficiency of heterogeneous photocatalysis for converting solar to chemical energy is low on a per photon basis mainly because of the difficulty of capturing and utilizing light across the entire solar spectral wavelength range. This challenge is addressed herein with a plasmonic superstructure, fashioned as an array of nanoscale needles comprising cobalt nanocrystals assembled within a sheath of porous silica grown on a fluorine tin oxide substrate. This plasmonic superstructure can strongly absorb sunlight through different mechanisms including enhanced plasmonic excitation by the hybridization of Co nanoparticles in close proximity, as well as inter- and intra-band transitions. With nearly 100% sunlight harvesting ability, it drives the photothermal hydrogenation of carbon dioxide with a 20-fold rate increase from the silica-supported cobalt catalyst. The present work bridges the gap between strong light-absorbing plasmonic superstructures with photothermal CO<sub>2</sub> catalysis toward the complete utilization of the solar energy.

Secure Transmission of Urologic Images and Records over the Internet (1999)

Photomailer MD provides a secure, convenient, and affordable method of transmitting patient images and records via the Internet. Transmission speed was significantly greater when using a T1 line and also tended to be faster when files were not encrypted. There was no significant difference in transmission time among the three encryption modes; therefore, 128-bit encryption with a password should be used to maximize security. Diagnostic accuracies were comparable to those in the literature. In general, 640 x 480-pixel resolution was adequate for urologic diagnoses, although higher-resolution images may improve accuracy.
NON-CONDENSING POLYMERIC GENE DELIVERY SYSTEMS: PRINCIPLES AND APPLICATIONS (2010)

Gene therapy holds tremendous promise in prevention and treatment of diseases as the approach is based on regulating the expression of genes that are responsible for pathological conditions. The biggest bottleneck for gene delivery has been the development of safe and efficacious delivery systems. Although non-viral vectors are considered as much safer options than their viral counterparts, they suffer from low transfection efficiency. In this review, we highlight the role of non-condensing polymeric delivery systems for oral and systemic gene delivery. Using evidence from contemporary literature, non-condensing polymeric microparticle and nanoparticle systems afford physical encapsulation of the nucleic acid construct and can be engineered for targeted delivery to tissues and cells. Additionally, these systems have shown less toxicity and afford sustained cytoplasmic DNA delivery for efficient nuclear uptake and transfection for both DNA vaccines and therapeutic genes.

Synthesis and Properties of Oligonucleotides Containing C8-Deoxyguanosine Arylamine Adducts of Borderline Carcinogens (2006)

C8-Arylamine-dG adducts of borderline carcinogens and the bladder and breast carcinogen 4-aminobiphenyl were prepared using cross-coupling chemistry. These adducts were converted into the corresponding C8-arylamine-5'-O-DMTr-2'-deoxyguanosine phosphoramidites and then used as building blocks for automated synthesis of site-specifically modified oligonucleotides. The oligonucleotides were characterized by UV melting temperature analysis, enzymatic digestion, and circular dichroism.
Spectroscopic Evidence of Low Energy Gaps Persisting Towards 120 Kelvin in Surface-Doped p-Terphenyl Crystals (2017)

The possibility of high temperature superconductivity in organic compounds has been discussed since the pioneering work of Little in 1964, with unsatisfactory progress until the recent report of a weak Meissner shielding effect at 120 Kelvin in potassium-doped para-terphenyl samples. To date however, no other signals of the superconductivity have been shown, including the zero-resistance state or evidence for the formation of the Cooper pairs that are inherent to the superconducting state. Here, using high-resolution photoemission spectroscopy on potassium surface-doped para-terphenyl crystals, we uncover low energy gaps that persist to approximately 120 K. Among a few potential origins for these gaps, we argue that the onset of electron pairing within molecules is most likely. And while pairing gaps are a prerequisite for high temperature superconductivity they do not guarantee it. Rather, the development of long-range phase coherence between the paired states on the molecules is necessary, requiring good wavefunction overlap between molecular states--something that is in general difficult for such weakly overlapping molecules.
Abstract 14232: Performance Of Cardiac Magnetic Resonance Fingerprinting Mapping - Evaluation By Comparison With Standard Techniques In A Large Patient Population (2021)

Background: Parametric mapping is now widely used as a part of cardiac MRI protocols. Cardiac Magnetic Resonance Fingerprinting (cMRF) techniques for parametric mapping allow for simultaneous evaluation of T1 and T2 within a single acquisition. In this study, we evaluate the performance of cMRF through comparison with clinically utilized pulse sequences for T1 and T2 in a large heterogeneous population. Hypothesis: cMRF T1 and T2 measurements agree with clinically available mapping sequences in a heterogeneous patient cohort. Methods: We obtained myocardial T1 and T2 values across the whole mid short axis slice of the left ventricle in 175 patients using cMRF (T1/T2), Modified Look-Locker Inversion Recovery (MOLLI, T1), and T 2 -prepared balanced steady-state free precession (bSSFP). Patients were classified into the groups “Ischemic cardiomyopathy (ICM)”, “Nonischemic Cardiomyopathy (NICM)”, “Normal”, and “Other”. The group classified as “Other” was not analyzed separately. Results: cMRF had similar T1 compared with MOLLI (1036 vs 1046 ms, p=0.06, r=0.76) and slightly lower T2 compared with bSSFP (46.1 vs 49.6 ms, p&lt;0.01, r=0.5) in the entire cohort. Mean T1 was higher in ICM compared to Normal when measured by both MRF (1074 vs 997, p&lt;0.01) and MOLLI (1073 vs 1015, p&lt;0.01). The same was true when comparing NICM and Normal for both MRF and MOLLI (p&lt;0.01). T1 was more concordant in NICM (r=0.82) vs ICM (r=0.46) and Normal (r=0.54) while T2 had similar concordance across the spectrum of pathologies. Bland-Altman plots showed good agreement between cMRF and MOLLI (Bias: -9.86, 95% CI: -98.58, 78.86)/bSSFP (Bias: -3.55, 95% CI: -11.68, 4.57). The concordance was stable across a range of heart rates. Conclusions: cMRF is an emerging technique for simultaneous T1/T2 mapping in the myocardium. In a large heterogeneous population, cMRF T1 and T2 values showed good agreement with clinically-utilized pulse sequences. Further work is needed to identify sources of discrepancies.
Acid‐Catalyzed Furfuryl Alcohol Polymerization: Characterizations of Molecular Structure and Thermodynamic Properties (2011)

Abstract The liquid‐phase polymerization of furfuryl alcohol catalyzed by sulfuric acid catalysts and the identities of molecular intermediates were investigated by using Raman spectroscopy and density functional theory calculation. At room temperature, with an acid catalyst, a vigorous furfuryl alcohol polymerization reaction was observed, whereas even at a high water concentration, furfuryl alcohol was very stable in the absence of an acid catalyst. Theoretical studies were carried out to investigate the thermodynamics of protonation of furfuryl alcohol, initiation of polymerization, and formation of conjugated dienes and diketonic species by using the B3LYP level of theory. A strong aliphatic CC band observed in the calculated and measured Raman spectra provided crucial evidence to understand the polymerization reaction mechanism. It is confirmed that the formation of a conjugated diene structure rather than a diketone structure is involved in the furfuryl alcohol polymerization reaction.
Characterization of biomaterials intended for use in the nucleus pulposus of degenerated intervertebral discs (2020)

Biomaterials for regeneration of the intervertebral disc must meet complex requirements conforming to biological, mechanical and clinical demands. Currently no consensus on their characterization exists. It is crucial to identify parameters and their method of characterization for accurate assessment of their potential efficacy, keeping in mind the translation towards clinical application. This review systematically analyses the characterization techniques of biomaterial systems that have been used for nucleus pulposus (NP) restoration and regeneration. Substantial differences in the approach towards assessment became evident, hindering comparisons between different materials with respect to their suitability for NP restoration and regeneration. We have analysed the current approaches and identified parameters necessary for adequate biomaterial characterization, with the clinical goal of functional restoration and biological regeneration of the NP in mind. Further, we provide guidelines and goals for their measurement. STATEMENT OF SIGNIFICANCE: Biomaterials intended for restoration of regeneration of the nucleus pulposus within the intervertebral disc must meet biological, biomechanical and clinical demands. Many materials have been investigated, but a lack of consensus on which parameters to evaluate leads to difficulties in comparing materials as well as mostly partial characterization of the materials in question. A gap between current methodology and clinically relevant and meaningful characterization is prevalent. In this article, we identify necessary methods and their implementation for complete biomaterial characterization in the context of clinical applicability. This will allow for a more unified approach to NP-biomaterials research within the field as a whole and enable comparative analysis of novel materials yet to be developed.

Scintillation recording and playback in free-space optical links (2016)

The performance of a free-space optical (FSO) communication system is strongly affected by optical scintillation. Scintillation fades can cause errors when the power on a detector falls below its noise floor while surges can overload a detector. The very long time scale of scintillation compared to a typical bit in an FSO link means that error-correcting protocols designed for fiber optic links are inappropriate for FSO links. Comparing the performance effects of different components, such as photodetectors or protocols, such as forward error correction, in the field is difficult because conditions are constantly changing. On the other hand, laboratory-based turbulence simulators may not really simulate the effects of long-range propagation through the atmosphere. We have investigated a different approach. Scintillation has been measured during field tests using FSO terminals by sending a continuous wave beam through the atmosphere. A high dynamic range photodetector was digitized at a 5-KHz rate and files of the intensity variations were saved. Many hours of scintillation data under different environmental conditions and at different sites have been combined into a library of data. A fiber-optic-based scintillation playback system was then used in the laboratory to test modems and protocols with the recorded irradiance files. This enabled comparisons using the same atmospheric conditions allowing optimization of such parameters as detector dynamic range. It also allowed comparison and optimization of different error correcting protocols.
Operating modes of a magnetized cold cathode plasma in helium 50–6400 mTorr (2019)

Abstract We characterize the operating modes of a magnetized cold cathode plasma in helium at pressures 50–6400 mTorr (6.7–850 Pa). We find at least three distinct modes: (i) a diffuse magnetron plasma with representative plasma voltage 250 V; (ii) a constricted mode with a bright spot at the cathode surface that moves slowly, with representative plasma voltage 50 V; and, (iii) a constricted mode (CO) with a bright spot at the cathode surface that orbits rapidly around the racetrack region defined by the magnetic field, with representative plasma voltage 80 V. This latter mode is of interest because it appears to be a cold-cathode plasma operating at unusually low voltage, and it is associated with a low rate of cathode mass-loss. We find that the CO mode appears only if the initial rate of current-rise is high, and if the cathode surface is smooth and featureless. It also appears to be correlated with cathode materials that form strong oxide films that can dramatically increase the field emission of electrons from the cathode surface.
Voltammetric and impedimetric properties of nano-scaled -Fe2O3 catalysts supported on multi-walled carbon nanotubes: catalytic detection of dopamine (2010)

The electron transfer and electrocatalytic proiperties of iron oxide nanoparticle (-Fe2O3) catalysts supported on MWCNTs are described. The MWCNT-Fe2O3 and its electrodes were successfully characterised with FESEM, HRTEM, XRD, EDX, cyclic voltammetry and electrochemical impedance spectroscopy. The MWCNT-Fe2O3 based electrodes demonstrated fastest electron transport and current response towards DA compared to other electrodes studied, giving a catalytic rate constant of 16.4 x 10 5 cm 3 mol
Leakage minimization using self sensing and thermal management (2010)

We have developed a system architecture, measuring and modeling techniques, and algorithms for on-line power and energy optimization and thermal management. The starting point for our approach is a simple and small gate-level network that can be used for real-time and low overhead measurement of temperature on chip positions where our network gates are placed. We use linear programming and interpolation to calculate the temperature at any arbitrary point of the integrated circuit. The periodic calculations of the temperature are used to estimate locally dissipated energies, which are consequently used to derive the most efficient use of operational times to minimize the overall leakage energy. All concepts and algorithms are experimentally validated using a simulation platform that consists of the Alpha 21364 processor and the SPEC benchmarks.
Detection sensitivity of influenza rapid diagnostic tests (2014)

The sensitivity of influenza rapid diagnostic tests (IRDTs) currently available in Japan for various influenza virus strains, including human H7N9 and H5N1 isolates, were compared and it was found that all of the IRDTs examined detected these viruses; however, their detection sensitivities differed.
