Multi-View Fusion of Sensor Data for Improved Perception and Prediction in Autonomous Driving (2022)

We present an end-to-end method for object detection and trajectory prediction utilizing multi-view representations of LiDAR returns and camera images. In this work, we recognize the strengths and weaknesses of different view representations, and we propose an efficient and generic fusing method that aggregates benefits from all views. Our model builds on a state-of-the-art Bird’s-Eye View (BEV) network that fuses voxelized features from a sequence of historical LiDAR data as well as rasterized high-definition map to perform detection and prediction tasks. We extend this model with additional LiDAR Range-View (RV) features that use the raw LiDAR information in its native, non-quantized representation. The RV feature map is projected into BEV and fused with the BEV features computed from LiDAR and high-definition map. The fused features are then further processed to output the final detections and trajectories, within a single end-to-end trainable network. In addition, the RV fusion of LiDAR and camera is performed in a straightforward and computationally efficient manner using this framework. The proposed multi-view fusion approach improves the state-of-the-art on proprietary large-scale real-world data collected by a fleet of self-driving vehicles, as well as on the public nuScenes data set with minimal increases on the computational cost.

Electronic Medical Record Review as a Surrogate to Telephone Follow-up to Establish Outcome for Diagnostic Research Studies in the Emergency Department (2005)

Background: Follow-up for diagnostic research studies might be facilitated if medical record review (MRR) could be used instead of telephone calls. Objectives: The authors hypothesized that MRR would yield similar accuracy to telephone follow-up. Methods: This was a secondary analysis of 2,178 initially disease-free patients who were followed after enrollment in a diagnostic study of either acute coronary syndrome (45 days) or pulmonary embolism (90 days) conducted in an urban teaching emergency department (ED). Disease status (positive or negative) was defined explicitly. Using structured data forms, trained researchers performed MRR using a comprehensive electronic database, and formulated an opinion about disease status. Trained researchers, blinded to the MRR, then dialed telephone numbers, asked questions from a script, and categorized disease status. The criterion standard was adjudication by consensus of two of three physicians who independently determined disease status based on explicit criteria and access to all follow-up data. Results: Adjudicators found that 13 of 2,178 patients developed disease during follow-up; all 13 true positives occurred among the 2,054 (94.3%) of patients who acknowledged intent to return to the study hospital. Telephone follow-up was successful in 81% of patients, and found all 13 true positives (sensitivity 100%) but with three additional false-positive cases. MRR disclosed 12 of 13 cases of disease (sensitivity 92%) with no false-positive cases. Further review of the one false-negative case from MRR revealed that it occurred after the prescribed time limit for follow-up. Conclusions: Under limited circumstances, accurate clinical follow-up for diagnostic studies conducted in the ED can be obtained by medical record review.

Syntheses of Vinca Alkaloids and Related Compounds. 104. A Concise Synthesis of (−)-Vincapusine1 (2006)

beta-Iodo-enamines with an eburnane skeleton (5a and 5c) were obtained with the aid of iodine from compounds 2a and 2c and were then transformed into hydroxyl lactams (6a and 6c) with CuSO4.5H2O in a mixture of DMF and water. Lactams (6a and 6c) were reduced selectively with BH3.SMe2 to result in the first synthesis of (-)-vincapusine (4a) as well as its natural 14-decarbomethoxy analogue (4c).
Characterization and Photochemistry of the Gallium and Indium Subhydrides Ga2H2 and In2H2 This work was supported by the Deutsche Forschungsgemeinschaft (Habilitation grant to H.-J. H.), the CNRS (L. M.), and the EPSRC (A. J. D.). (2002)

The five binary species Ga(μ-H)2Ga, In(μ-H)2In (see left structure), HGaGaH, HInInH (center), and GaGaH2 (right) were prepared by matrix isolation and characterized unambiguously by IR spectroscopy and quantum-chemical calculations. Investigations of the photochemical properties reveal that each of the isomers can be interconverted by photolysis.

PET Study of the M<sub>1</sub>-Agonists [<sup>11</sup>C]Xanomeline and [<sup>11</sup>C]Butylthio-TZTP in Monkey and Man (1996)

Xanomeline, a substituted TZTP, is a new M1 selective muscarinic agonist in clinical trials for Alzheimer's disease. The brain uptake of [11C]xanomeline and the analog [11C]butylthio-TZTP was examined by positron emission tomography (PET). Radioactivity accumulated most markedly in the neocortex and the striatum. Pharmacological characterization in vitro and in cynomolgus monkeys in vivo by PET indicated specific [11C]butylthio-TZTP binding to muscarinic receptors and to sigma-1 recognition sites. More than 5% of the radioactivity was in the human brain 5 min after i.v. injection of [11C]xamomeline or [11C]butylthio-TZTP. This high brain uptake may be clinically advantageous in the sense that substituted TZTP may induce central muscarinic agonist effects at a dose level for which there is a low risk of peripheral side-effects.

Utilization of Solid Waste for Activated Carbon Production in Space (2003)

&lt;div class="htmlview paragraph"&gt;Activated carbons have a unique capability of strongly absorbing a great variety of species, ranging from SO&lt;sub&gt;2&lt;/sub&gt; and NO&lt;sub&gt;x&lt;/sub&gt;, to trace organics, mercury, and other heavy metals. Activated carbons can also be used for gas storage and gas separations, including systems of practical interest to NASA (e.g., CO&lt;sub&gt;2&lt;/sub&gt;/N&lt;sub&gt;2&lt;/sub&gt;/O&lt;sub&gt;2&lt;/sub&gt;), and even for the purification of liquids. No single activated carbon is suitable for all applications, but appreciable control over sorbent properties can be exercised in the process of carbon preparation. Since activated carbons can be produced from a wide range of organic materials, including waste streams, the preparation of activated carbons on board spacecraft should involve a limited amount of additional resources, help manage on-board waste, and reduce the weight of materials to be launched from earth. The feasibility of producing waste-derived activated carbons suitable for SO&lt;sub&gt;2&lt;/sub&gt; and NO control was the subject of the current study. The conclusions from this work are as follows: 1) high levels of NO and SO&lt;sub&gt;2&lt;/sub&gt; removal (up to 95%) were obtained with biomass-derived sorbents; 2) at low temperatures, the biomass sorbent performance was even better than that obtained with a commercial activated carbon which had a much higher nominal BET surface area (793 m&lt;sup&gt;2&lt;/sup&gt;/g versus 292 m&lt;sup&gt;2&lt;/sup&gt;/g); 3) in general, catalyst impregnation of wheat straw chars was successful, despite the microporous nature of these materials, and resulted in improved sorbent performance (higher removal efficiencies); 4) activation of the biomass (wheat straw) derived char with CO&lt;sub&gt;2&lt;/sub&gt; resulted in relatively high surface areas (∼300 m&lt;sup&gt;2&lt;/sup&gt;/g) compared to most literature results for similar materials.&lt;/div&gt;
Upregulation of the signal transducers and activators of transcription 3 (STAT3) pathway in lymphatic metastases of papillary thyroid cancer. (2011)

Papillary thyroid cancer (PTC) has an impressive propensity for lymphatic spread. Signal transducers and activators of transcription 3 (STAT3), constitutively activated in many different cancers, may play a role in PTC lymphatic metastases. We examined 49 patients with PTC, 22 with and 27 without lymphatic metastases. All patients had a total thyroidectomy with lymph node dissection to document true node negative cases. The level of STAT3 expression in benign, non-neoplastic thyroid tissue is barely detectable by immunohistochemistry. Only 11 of the 35 (31%) specimens exhibited weak immunostainingfor STAT3 and pSTAT3 was found weakly positive in 3 of 35 (9%) benign specimens. Expression of STAT3 in all PTC primary tumors was 98% (40/41) and thus significantly higher than corresponding benign thyroid tissue (p=0.0001). pSTAT3 was found in 37% of primary tumors (15/41) and this was significantly higher than pSTAT3 expression in benign tissue (p=0.006). Comparing node-positive and node-negative primary tumors, there was no difference in staining intensity for STAT3 where strong (2+) staining was seen 12/19 node-positive tumors and 13/22 node-negative tumors (p=1). Regarding pSTAT3 expression in primary PTC tumors, node negative cases (n=22) exhibited significantly less staining compared to node positive cases (n=19). Only 4 of 22 (18%) cases in the node-negative group were weakly (1+) positive for pSTAT3 while 12 of 19 (58%) cases in the node-positive group were positive (p=0.011) with 45% of these specimens exhibiting strong (2+) staining. Lymphatic metastases were highly positive (>93%) for both STAT3 and pSTAT3. The STAT3 pathway is ubiquitous in PTC and activated pSTAT3 is significantly upregulated in PTC tumors with metastatic disease. This study is the first to suggest a potential role for activated pSTAT3 in lymphatic metastases in thyroid cancer.
Virtual reality enabled asynchronous learning modules for fiber opticpreform manufacturing education (2023)

The demand for skilled workers and novel manufacturing training solutions has increased with the growing demand for fiber optic cables. Web-based simulations can be used for training, and this paper presents an approach for developing a fiber preform manufacturing browser-based VR simulation. Subsequently, a study was conducted to evaluate the effectiveness of the simulation based on learning gains and learner perception of ease of use, usefulness, intention of use, learning outcomes, and workload. A mixed-methods between-subjects study with 63 participants found that the combination of lecture and simulation was significantly better for perceived usefulness and learning outcomes compared to lecture-only or lecture-and-video conditions.
Application of particle enlargement by condensation to industrial dust collection. (1978)

Application of the phenomena of particle growth by condensation to industrial dust collection was studied. The analysis to evaluate the extent of size enlargement was first introduced to the two essential and industrially useful methods, one of which is the mixing of hot saturated air with cold air, the other being injection of steam into air. Four typical processes are proposed for effective application to industrial exhaust gas and the procedure of using these processes is illustrated according to the various conditions of exhaust gas. The technique for size enlargement of aerosol particles by condensation was found to be essentially applicable to any industrial exhaust gas which contains submicron dust particles in low number concentration when the appropriate process shown herein is selected.
The Yaa locus Confers Apoptosis, NF-κB and Rapamycin Signaling Resistance Through Multiple Receptors in C57BL/6J Mice (129.12) (2007)

Abstract BXSB/MpJ mice develop a spontaneous SLE-like disease that is remarkably accelerated in males, due to the presence of the Y-linked-autoimmune accelerator locus (Yaa). Recent insights into the molecular nature of the Yaa mutation were provided when an additional copy of 17 distally located X chromosome genes were discovered on the Y-chromosome of Yaa mice. Included within this region is the gene TLR7, a toll receptor which binds ssRNA and is functionally expressed on B-cells and monocyte derived lineages. Previous reports have suggested that the SLE-like disease phenotype conveyed by Yaa is due to the duplication of TLR7, which causes a shift toward anti-nucleolar antigens in B6.FcγRIIB(−/−). We show here that B6, BXSB and MRL mice that carry Yaa rarely display the anti-nucleolar antibody pattern. We found that B cells of Yaa mice display novel phenotypes consistent with increased rapamycin and NF-κB signaling through receptors other than TLR7, including TLR4, TLR9, and the BCR. In addition, Yaa B cells are resistant to anti-IgM induced apoptosis. These results demonstrate that the copy number of a single receptor can influence the strength of signaling through other receptors and/or that additional genes within the duplicated region contribute toward the Yaa phenotype.

Super‐reactive Nanoenergetic Gas Generators Based on Periodate Salts (2013)

Nanoenergetic formulations under flash heating: Periodate salt nanoparticles are synthesized by a facile aerosol spray drying process and demonstrate highly reactive properties as oxidizers in an aluminum-based nanoenergetic formulation. Direct evidence supports that gas phase oxygen release from the oxidizer decomposition is critical in the ignition and combustion of these formulations.
Sympathetic‐mediated hypertension of awake juvenile rats submitted to chronic intermittent hypoxia is not linked to baroreflex dysfunction (2009)

In the present study, we evaluated the mechanisms underpinning the hypertension observed in freely moving juvenile rats submitted to chronic intermittent hypoxia (CIH). Male juvenile Wistar rats (20-21 days old) were submitted to CIH (6% O(2) for 40 s every 9 min, 8 h day(1)) for 10 days while control rats were maintained in normoxia. Prior to CIH, baseline systolic arterial pressure (SAP), measured indirectly, was similar between groups (86 +/- 1 versus 87 +/- 1 mmHg). After exposure to CIH, SAP recorded directly was higher in the CIH (n = 28) than in the control group (n = 29; 131 +/- 3 versus 115 +/- 2 mmHg, P < 0.05). This higher SAP of CIH rats presented an augmented power of oscillatory components at low (10.05 +/- 0.91 versus 5.02 +/- 0.63 mmHg(2), P < 0.05) and high (respiratory-related) frequencies (12.42 +/- 2.46 versus 3.28 +/- 0.61 mmHg(2), P < 0.05) in comparison with control animals. In addition, rats exposed to CIH also exhibited an increased cardiac baroreflex gain (3.11 +/- 0.08 versus 2.1 +/- 0.10 beats min(1) mmHg(1), P < 0.0001), associated with a shift to the right of the operating point, in comparison with control rats. Administration of hexamethonium (ganglionic blocker, i.v.), injected after losartan (angiotensin II type 1 receptor antagonist) and [beta-mercapto-beta,beta-cyclopenta-methylenepropionyl(1), O-Me-Tyr(2), Arg(8)]-vasopressin (vasopressin type 1a receptor antagonist), produced a larger depressor response in the CIH (n = 8) than in the control group (n = 9; 49 +/- 2 versus 39 +/- 2 mmHg, P < 0.05). Fifteen days after the cessation of exposure to CIH, the mean arterial pressure of CIH rats returned to normal levels. The data indicate that the sympathetic-mediated hypertension observed in conscious juvenile rats exposed to CIH is not secondary to a reduction in cardiac baroreflex gain and exhibits a higher respiratory modulation, indicating that an enhanced respiratory-sympathetic coupling seems to be the major factor contributing to hypertension in rats exposed to CIH.
Polarization Dependence Analysis of Optical Loss in Small-Aperture Metal Waveguides for Near-Field Optics (2001)

Optical intensity profile and optical loss in small-aperture metal waveguides were analyzed by a one-dimensional waveguide model and the beam propagation method. Guided mode profile and optical loss have a great dependence on the polarization direction of the guided lightwave. The loss for the TM 0 mode is two orders of magnitude smaller than that for the TE 0 mode for a slit width of less than half-wavelength. A very small spot is available at high efficiency by using a metal waveguide and an incident light with TM polarization.
Adsorptive Separation of Propylene and Propane on a Porous Metal-Organic Framework, Copper Trimesate (2010)

The separation of propane and propylene has been commercially performed by an energy-intensive distillation process at about 243 K and 0.3 MPa in a column containing over 100 trays to achieve polymer-grade propylene due to the physicochemical similarities.
Keep on moving! Exploring anthropomorphic effects of motion during idle moments (2017)

In this paper, we explored the effect of a robot's subconscious gestures made during moments when idle (also called adaptor gestures) on anthropomorphic perceptions of five year old children. We developed and sorted a set of adaptor motions based on their intensity. We designed an experiment involving 20 children, in which they played a memory game with two robots. During moments of idleness, the first robot showed adaptor movements, while the second robot moved its head following basic face tracking. Results showed that the children perceived the robot displaying adaptor movements to be more human and friendly. Moreover, these traits were found to be proportional to the intensity of the adaptor movements. For the range of intensities tested, it was also found that adaptor movements were not disruptive towards the task. These findings corroborate the fact that adaptor movements improve the affective aspect of child-robot interactions (CRI) and do not interfere with the child's performances in the task, making them suitable for CRI in educational contexts.

The Isolation of Ricinoleic Acid from Castor Oil by Salt‐solubility‐based Fractionation for the Biopharmaceutical Applications (2007)

Abstract The goal of this work was to develop a method for the preparative isolation of ricinoleic acid (RA) from Castor oil (CO) for use as building blocks in biopharmaceutical synthesis. The separation efficiency achieved with the impurity extraction approach (IEA) and the salting‐out approach (SOA) based on utilization of monobasic alkali salt of RA was examined. SOA showed better separation efficiency. Fractional precipitation from the co‐solvent system consisting of isopropyl ether:ethanol (IPE:EtOH) 65:35 v/v and applied at a CO: co‐solvent system mass: volume ratio of 1:5 produced a high quality purified RA (purity 97.9–98.6%). It contains residuals of linoleic acid and oleic acid as the main impurities and satisfies all requirements of the official compendia for oleaginous vehicles for parenteral administration. The total yield of this process was 55.5 ± 2.5% and the recovery of RA was about 70% (calculated relatively to the yield of the crude product). The study of the synthesis kinetics of RA oligomers and of the biopolymer prepared from these oligomers indicated that mono‐functional fatty acids (FAs) affect the composition of the oligomers' mixture and delay chain elongation of both RA oligomers and biopolymer. The developed novel process is simple, flexible, highly reproducible, inexpensive, and has high scalability potential.
