Trajectory prediction of cyclists using a physical model and an artificial neural network (2016)

This article presents two methods for predicting the trajectories of cyclists at an intersection and compares them to a Kalman Filter (KF) approach. The first method uses a physical model of cyclists to predict their future position. The second method is based on a polynomial least-squares approximation in combination with a multilayer perceptron artificial neural network and is able to predict the future position of cyclists independent of their motion type such as “Starting”, “Stopping”, “Waiting” or “Passing”. To evaluate the performance of the methods, 566 tracks (394 for training, 172 for testing) of uninstructed cyclists were recorded at a public intersection using a wide angle stereo camera system and laser scanners. Using the tracks as input data, the future trajectory was predicted for a time horizon of 2.5 s. For starting motions the prediction using the physical model leads to 27% more accurate positions than the KF approach for a forecast horizon of 2.5 s. The neural network shows a 34% more accurate result for starting and stopping motions and a similar result for waiting and passing motions.
Position-Dependent Silencing of Germline Vβ Segments on TCRβ Alleles Containing Preassembled VβDJβCβ1 Genes (2010)

The genomic organization of TCRbeta loci enables Vbeta-to-DJbeta2 rearrangements on alleles with assembled VbetaDJbetaCbeta1 genes, which could have deleterious physiologic consequences. To determine whether such Vbeta rearrangements occur and, if so, how they might be regulated, we analyzed mice with TCRbeta alleles containing preassembled functional VbetaDJbetaCbeta1 genes. Vbeta10 segments were transcribed, rearranged, and expressed in thymocytes when located immediately upstream of a Vbeta1DJbetaCbeta1 gene, but not on alleles with a Vbeta14DJbetaCbeta1 gene. Germline Vbeta10 transcription was silenced in mature alphabeta T cells. This allele-dependent and developmental stage-specific silencing of Vbeta10 correlated with increased CpG methylation and decreased histone acetylation over the Vbeta10 promoter and coding region. Transcription, rearrangement, and expression of the Vbeta4 and Vbeta16 segments located upstream of Vbeta10 were silenced on alleles containing either VbetaDJbetaCbeta1 gene; sequences within Vbeta4, Vbeta16, and the Vbeta4/Vbeta16-Vbeta10 intergenic region exhibited constitutive high CpG methylation and low histone acetylation. Collectively, our data indicate that the position of Vbeta segments relative to assembled VbetaDJbetaCbeta1 genes influences their rearrangement and suggest that DNA sequences between Vbeta segments may form boundaries between active and inactive Vbeta chromatin domains upstream of VbetaDJbetaCbeta genes.
lnterleukin-6 Production by Draining Lymph Node Cells following Primary Contact Sensitisation of Mice: Relationship to the Proliferative Response (1994)

Interleukin-6 (IL-6) production and proliferative responses by draining lymph node cells were studied in mice exposed topically to a series of chemicals. Chemicals with the capacity to induce sensitisation, but not non-sensitisers, promoted both IL-6 production and lymph node cell proliferation ex vivo. The responses exhibited similar kinetics, were dependent upon the dose of topically applied allergen, and correlated significantly. We demonstrate that the main source of IL-6 within draining lymph nodes is not proliferating T lymphocytes. The induction of a strong IL-6 response, and the relationship of this to cellular proliferation indicate that production of this cytokine within the lymph node is closely associated with the induction of contact sensitivity in mice.
Solid neon sources for plasmas and x-ray lasers (1985)

A thin layer of frozen neon is condensed onto a cryogenically cooled substrate for use in generating a neon plasma for x-ray laser research. The freezing process and quasiequilibrium state of the layer are discussed. Spectral purity of a neon plasma formed by laser irradiation has been demonstrated. Control of the layer thinness is possible.
Unexpected similarity between HIV-1 reverse transcriptase and tumor necrosis factor binding sites revealed by computer vision (2021)

Rationalizing the identification of hidden similarities across the repertoire of druggable protein cavities remains a major hurdle to a true proteome-wide structure-based discovery of novel drug candidates. We recently described a new computational approach (ProCare), inspired by numerical image processing, to identify local similarities in fragment-based subpockets. During the validation of the method, we unexpectedly identified a possible similarity in the binding pockets of two unrelated targets, human tumor necrosis factor alpha (TNF-α) and HIV-1 reverse transcriptase (HIV-1 RT). Microscale thermophoresis experiments confirmed the ProCare prediction as two of the three tested and FDA-approved HIV-1 RT inhibitors indeed bind to soluble human TNF-α trimer. Interestingly, the herein disclosed similarity could be revealed neither by state-of-the-art binding sites comparison methods nor by ligand-based pairwise similarity searches, suggesting that the point cloud registration approach implemented in ProCare, is uniquely suited to identify local and unobvious similarities among totally unrelated targets.
NASA’s Earth Science Technology Office CubeSats for Technology Maturation (2013)

NASA's Earth Science Technology Office (ESTO) has been supporting the development of multiple CubeSats to advance various technologies for future Earth Science observations. The goal of this work is to support instrument and information systems technology risk reduction, through flight validation in the space environment, in support of the Earth Science Decadal Survey. Within the next 18 months three CubeSats will have completed system development and testing. Two will launch on GEMSat L-39 planned no earlier than December 2013 while the third will launch no earlier than October 2014. MCubed/COVE-2 (a reflight mission) will take mid-resolution images of the Earth at approximately 200m per pixel while carrying the COVE payload. COVE will validate a real-time high data rate image processing algorithm utilizing the radiation-hardened, space-grade Virtex-5QV FPGA by Xilinx. This is a key capability for the Multiangle Spectropolarimetric Imager (MSPI) instrument planned for the ACE Decadal Survey mission concept. The IPEX CubeSat will validate autonomous science and product delivery technologies demonstrating a twenty-times reduction in data volume for low-latency near real-time product generation. This technology supports the proposed HyspIRI mission concept VSWIR spectrometer and thermal IR imager. Finally, GRIFEX will perform engineering assessments of a state-of-the-art all digital in-pixel high frame rate Read-Out Integrated Circuit (ROIC). Its high throughput capacity will enable the GEO-CAPE mission concept to make hourly high spatial and spectral resolution measurements of rapidly changing atmospheric chemistry and pollution with the Panchromatic Fourier Transform Spectrometer (PanFTS) instrument.
An asynchronous time-based image sensor (2008)

In this paper we propose a fully asynchronous, time- based image sensor, which is characterized by high temporal resolution, low data rate (near complete temporal redundancy suppression), high dynamic range, and low power consumption. Autonomous pixels asynchronously communicate the detection of relative changes in light intensity, and the time from change detection to the threshold crossing of a photocurrent integrator, so encoding the instantaneous pixel illumination shortly after the time of a detected change. The chip is being implemented in a standard 0.18 mum CMOS process and measures less than 10times8 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> at 304times240 pixel resolution.
Design and implementation of a home stroke telerehabilitation system (2009)

Motor retraining following stroke can occur through intensive, repetitive motion tasks that require concentration to promote new connections in the brain. Conducting intensive, repetitive therapy in the clinic is time consuming for both patient and therapist. A home-based, clinician-directed tracking training system for rehabilitation is presented. Two biofeedback motion training systems have been developed, one for hand and wrist motor relearning and the other for the ankle. The systems include a potentiometer joint sensor, a smart box interface and a laptop host computer. An internet connection allowed for periodic video teleconferencing between patient and therapist. The hand/wrist system was evaluated in a pilot project with 24 subjects. The results demonstrated technical feasibility for the technology. The ankle system is currently undergoing evaluation.
Mars submillimeter sensor on microsatellite: sensor feasibility study (2018)

Abstract. We present a feasibility study for a submillimeter instrument on a small Mars platform now under construction. The sensor will measure the emission from atmospheric molecular oxygen, water, ozone, and hydrogen peroxide in order to retrieve their volume mixing ratios and the changes therein over time. In addition to these, the instrument will be able to limit the crustal magnetic field, and retrieve temperature and wind speed with various degrees of precision and resolution. The expected measurement precision before spatial and temporal averaging is 15 to 25 ppmv for the molecular oxygen mixing ratio, 0.2 ppmv for the gaseous water mixing ratio, 2 ppbv for the hydrogen peroxide mixing ratio, 2 ppbv for the ozone mixing ratio, 1.5 to 2.5 µT for the magnetic field strength, 1.5 to 2.5 K for the temperature profile, and 20 to 25 m s−1 for the horizontal wind speed.

Semantically linked photos for building Visual Web (2015)

Summary form only given. The twenty-first century brought a new revolution in information technology. Capturing, storing, and sharing photos have now become easier than corresponding operations using text. This is a major change in the way information gets created, communicated, and consumed. According to estimates the number of photos captured in 2014 is 900 Billion! A photo represents a moment. The moment is usually related to an event at which more photos may have been captured. Each photo is taken at a place, with some associated emotions, may contain people and many objects that may also appear in other photos. Thus, a photo may be linked to many other photos along different dimensions. One may also create explicit links among photos or objects in photos. All these photos on the Web form a Visual Web that links photos with other photos and other information elements. This Visual Web has many new challenges. It also offers opportunities to address new societal issues and solve many difficult yet unsolved problems. In this paper, we will discuss nature of the Visual Web, technical challenges, and some interesting opportunities in this area.

Synthesis of fluorine‐containing star‐shaped poly(vinyl ether)s via arm‐linking reactions in living cationic polymerization (2012)

Abstract Various types of fluorine‐containing star‐shaped poly(vinyl ether)s were successfully synthesized by crosslinking reactions of living polymers based on living cationic polymerization. Star polymers with fluorinated arm chains were prepared by the reaction between a divinyl ether and living poly(vinyl ether)s with fluorine groups (C 4 F 9 , C 6 F 13 , and C 8 F 17 ) at the side chain using cationogen/Et 1. 5 AlCl 1. 5 in a fluorinated solvent (dichloropentafluoropropanes), giving star‐shaped fluorinated polymers in high yields with a relatively narrow molecular weight distribution. The concentration of living polymers for the crosslinking reaction and the molar feed ratio of a bifunctional vinyl ether to living polymers affected the yield and molecular weight of the star polymers. Star polymers with block arms were prepared by a linking reaction of living block copolymers of a fluorinated segment and a nonfluorinated segment. Heteroarm star‐shaped polymers containing two‐ or three‐arm species were synthesized using a mixture of different living polymer species for the reaction with a bifunctional vinyl ether. The obtained polymers underwent temperature‐induced solubility transitions in various organic solvents, and their concentrated solutions underwent sol–gel transitions, based on the solubility transition of a thermoresponsive fluorinated segment. Furthermore, a slight amount of fluorine groups were shown to be effective for physical gelation when those were located at the arm ends of a star polymer. © 2012 Wiley Periodicals, Inc.

An expandable Petri Net Framework for method Behavior evaluation of reconfigured equipment (2010)

Abstract—This paper proposed a design approach for evaluating the feasibility of Reconfigurable Equipment Behavior (REB) based on the Extendable Petri Nets Framework (EPNF). The approach can analyze equipment scenarios through developing and usage phases. Most importantly, EPNF is fully automatic to build a Petri nets (PNs) model according to equipment scenarios of Unified Modeling Language (UML). Moreover, it also can enhance efficiency of production system. Adopting a cluster tool (CT) of semiconductors was presented as a case study to illustrate the proposed approach.
Pilot study of all-trans retinoic acid as post-remission therapy in patients with acute promyelocytic leukemia. (1995)

Chemotherapy may decrease relapses of acute promyelocytic leukemia (APL) following induction with all-trans retinoic acid (ATRA), however the optimal timing of these two modalities remains to be determined. We treated eight patients with morphologic evidence of APL with intensive induction chemotherapy followed by ATRA (45 mg/m2/d for 10 weeks). All eight patients achieved a complete remission following chemotherapy. After a median follow-up of 29.0 months, seven patients remain in complete remission; one patient relapsed at 26.9 months. RT-PCR analysis for the PML/RAR alpha rearrangement was performed to monitor patients for evidence of minimal residual disease. Both of the patients with persistence of this rearrangement after induction chemotherapy converted to negative following ATRA. Toxicity of ATRA given in the post-remission setting was mild and consisted of headache, dry skin, and elevations of triglycerides and transaminases. No patient developed evidence of the retinoic acid syndrome. The administration of ATRA after intensive induction chemotherapy is associated with durable remissions and minimal toxicity in patients with APL. Disappearance of the PML/RAR alpha rearrangement after ATRA suggests that ATRA is effective against minimal residual disease.
Micro-bore Column Fast Gas Chromatography-Mass Spectrometry in Essential Oil Analysis (2008)

The present research is focused on the use of micro-bore column fast gas chromatography in combination with rapid-scanning quadrupole mass spectrometry for mediumly-complex essential oil analysis. A basil essential oil sample was initially subjected to conventional GC-MS (analysis time: 25 min) under optimum analytical conditions. Peak identification was carried by using a dual-filtered MS library search procedure: the first filter deleted “hits” with a less than 90% spectral similarity, while the second filter eliminated matches with a linear retention index (LRI) outside a pre-defined LRI window. The same essential oil sample was analyzed under optimized fast GC-MS conditions by using a micro-bore column, with the same aforementioned MS library search process (analysis time: 5.3 min). Resolution was altogether similar in both applications, with the same number of compounds reliably-identified, namely fifty-nine. The experiment demonstrated the usefulness of the rapid GC approach in this type of experiment.
HIV Vaccine Triage: Halakhic Considerations (2013)

This chapter offers hypothetical suggestions on how Jewish bioethics might be applied to the distribution of a vaccine against HIV, should one become available in the future. During a time of pandemic — and the rate of HIV morbidity and mortality in today's world represents a true pandemic — inoculating the public against HIV would have as much lifesaving potential as medications for the symptoms of patients already infected with HIV. Through the prism of halakhic approaches to the allocation of scarce resources, the questions raised by the hypothetical possibility of dispensing an anti-HIV vaccine. When the question of HIV vaccine allocation is a matter of oneself vs. others, then, one inoculates oneself first. With respect to an HIV vaccine, all members of any given society would appear to be roughly equal. The danger of exposure to HIV in that society, and the lifesaving efficacy of the vaccine, are identical for all citizens.
The intelligent product driven supply chain (2003)

Establishing connectivity of products with real-time information about themselves can at one level provide accurate data, and at another, allow products to assess and influence their own destiny. In this way, the specification for an intelligent product is being built - one whose information content is permanently bound to its material content. This paper explores the impact of such development on supply chains, contrasting between simple and complex product supply chains. The Auto-ID project is on track to enable such connectivity between products and information using a single, open-standard, data repository for storage and retrieval of product information. The potential impact on the design and management of supply chains is immense. This paper provides an introduction to of some of these changes, demonstrating that by enabling intelligent products, Auto ID systems will be instrumental in driving future supply chains. The paper also identifies specific application areas for this technology in the product supply chain.
Electrophysiological study of the action of angiotensin II on the rat myometrium. (1979)

Angiotensin II (A II) produces a contraction of visceral and vascular smooth muscles of different species. The accompanying electrophysiological changes were measured on strips of rat myometrium at 35 degrees C using the double sucrose-gap technique. A II at concentrations from 5 x 10(-10) to 10(-6)M produces a depolarization and an increase in membrane conductance. This increase in membrane conductance is not membrane potential dependent since it is observed even when the membrane potential is maintained at the resting level. When all Na + in the test solution is replaced by either Li + or Mg (2+), the depolarizing effect of 10(-6)M A II is either markedly reduced or abolished. Under these conditions, A II produces a small initial hyperpolarization, which is modified by external potassium concentration changes and abolished by tetraethylammonium chloride. When all Cl- is replaced by either NO (-3) or cyclohexanesulfamate, A II (10(-6) M) still produces a 20-m V depolarization. The removal of extracellular Ca (2+) or K+ does not have any effect on the depolarizing action of A II, which also is not changed by 10(-3) M ouabain. In conclusion, A II produces a depolarization of the uterine smooth muscle membrane through an increase in the membrane conductance to Na+. The membrane conductance to potassium is increased simultaneously. The contraction induced by A II shows two components: a phasic component triggered by the Ca (2+) entry associated with spike production and a tonic component due to the release of Ca(2+) from intracellular stores.
American Indians fitting into Medical School (1999)

This paper describes a qualitative study of how indigenous people experience medical school in the United States. Nine American Indians and Alaska Natives participated in the study: five women and four men. They came from eight different tribes, but they have asked me to protect their confidentiality, so I will not identify their tribes. Their ages ranged from 27 to 39. Five of them had children. Two of them were unmarried. In the United States, the need for indigenous physicians is great. Twice as many American Indians die from homicide and suicide as non-Indians in the United States (Wallace, Kirk, Houston, Amnest, and Emrich, 1993); three times as many die from accidents and more than four times as many die from alcoholism (Indian Health Service, 1996). Diabetes is rampant among American Indians and Alaska Natives. Women are the hardest hit (Gilliland, Gilliland, and Carter; 1997). More than five times as many American Indian and Alaska Native women die from diabetes than non-Latina white women.
Eye-R, a glasses-mounted eye motion detection interface (2001)

Eye-R is a system designed to detect and communicates the intentional information conveyed in eye movement. This glasses-mounted, wireless device stores and transfers information based on user eye motion and external IR devices thus promoting an enriched experience with their environment. This paper describes how the system measures eye motion and utilizes this as an implicit input channel to a sensor system and computer. In the primary scenario, eye motion detection is used to recognize a users gaze. When the person's eyes are fixated the system infers that they are paying attention to something in their environment and then tries to facilitate an exchange of information in either direction on the user's behalf.
