3-D Localization and Mapping Using a Single Camera Based on Structure-from-Motion with Automatic Baseline Selection (2006)

This paper presents a system of 3-D simultaneous localization and mapping (SLAM) using monocular vision-based on the structure-from-motion scheme. An crucial issue in applying structure-from-motion to SLAM is that accuracy depends heavily on the baseline distance. We address this problem by selecting an appropriate baseline based on criteria for the tradeoff between the baseline distance and the number of feature points visible in the images. Experimental results show that full 3-D sparse maps with camera trajectory were built from images captured with a handy camera.
A Photoresponsive Hyaluronan Hydrogel Nanocomposite for Dynamic Macrophage Immunomodulation (2018)

Macrophages are a predominant immune cell population that drive inflammatory responses and exhibit transitions in phenotype and function during tissue remodeling in disease and repair. Thus, engineering an immunomodulatory biomaterial has significant implications for resolving inflammation. Here, a biomimetic and photoresponsive hyaluronan (HA) hydrogel nanocomposite with tunable 3D extracellular matrix (ECM) adhesion sites for dynamic macrophage immunomodulation is engineered. Photodegradative alkoxylphenacyl-based polycarbonate (APP) nanocomposites are exploited to permit user-controlled Arg-Gly-Asp (RGD) adhesive peptide release and conjugation to a HA-based ECM for real-time integrin activation of macrophages encapsulated in 3D HA-APP nanocomposite hydrogels. It is demonstrated that photocontrolled 3D ECM-RGD peptide conjugation can activate αvβ3 integrin of macrophages, and periodic αvβ3 integrin activation can enhance anti-inflammatory M2 macrophage polarization. Altogether, an emerging use of biomimetic, photoresponsive, and bioactive HA-APP nanocomposite hydrogel is highlighted to command 3D cell-ECM interactions for modulating macrophage polarization, which may shed light on cell-ECM interactions in innate immunity and inspire new biomaterial-based immunomodulatory therapies.
Reduction languages for reduction machines (1974)

This paper describes a particular realization of a Lambda-Red language as a machine language. Parts of it resemble the Lambda Calculus or a transposed form of it. A constructor syntax is employed such that a linearized preorder representation of the syntax tree is the information structure on which the machine operates. Instances of reduction rules are recognized by combinations of constructors and atoms. Reduction rules with 1, 2 and 3 constructors and/or atoms have been described.A recursive control structure forms the essential part of the implementation. There is a one to one correspondence between constructor syntax and control structure rather than a simulation of recursive structure by von Neumann type instruction sequencing. Thus the system is easily expandable by new constructors and atoms. Execution, that is the application of reduction rules, is subsumed under editing. Emphasis has been on the following pragmatic concepts: locality of action, directness, and security. There are no error messages, errors appear as irreducible expressions. There is no "RUN" instruction, instead the number of reductions to be performed is specified. Whatever happens - it is restricted to subexpressions. The user has the security that all his actions are limited and predictable.The machine language resembles a higher level programming language, but it is "variable-free": expressions are named, not boxes which contain expressions. There seems to be a concept of late binding. However, this is not made a matter of principle, but a matter of degree. Between a general statement of a problem and the result are many intermediate representations - all in the same language - corresponding to various degrees of binding parameters. The user has complete freedom in the choice of variable names. There is a specially developped protection system which avoids confusion of variables.The efficiency of the system is limited by the rate characters can be processed which is essentially determined by the control store cycletime. Measurements will be performed as soon as a simulation of the system is available. Three other important subjects, namely arithmetic, the definition of constants, and source sink input-output will be reported later.

Monoclonal antibody-conjugated popcorn-shape gold nanotechnology-driven approach to selectively detect multiple drug resistant (MDRB) Salmonella typhimurium DT104 bacteria has been developed. We demonstrate that the gold nanotechnology based assay is capable of measuring the amount of MDRB in food samples.
<b> <i>Retraction:</i> </b> Detection, Characterization, and Spontaneous Differentiation In Vitro of Very Small Embryonic-Like Putative Stem Cells in Adult Mammalian Ovary (2011)

The present study was undertaken to detect, characterize, and study differentiation potential of stem cells in adult rabbit, sheep, monkey, and menopausal human ovarian surface epithelium (OSE). Two distinct populations of putative stem cells (PSCs) of variable size were detected in scraped OSE, one being smaller and other similar in size to the surrounding red blood cells in the scraped OSE. The smaller 1-3 μm very small embryonic-like PSCs were pluripotent in nature with nuclear Oct-4 and cell surface SSEA-4, whereas the bigger 4-7 μm cells with cytoplasmic localization of Oct-4 and minimal expression of SSEA-4 were possibly the tissue committed progenitor stem cells. Pluripotent gene transcripts of Oct-4, Oct-4A, Nanog, Sox-2, TERT, and Stat-3 in human and sheep OSE were detected by reverse transcriptase-polymerase chain reaction. The PSCs underwent spontaneous differentiation into oocyte-like structures, parthenote-like structures, embryoid body-like structures, cells with neuronal-like phenotype, and embryonic stem cell-like colonies, whereas the epithelial cells transformed into mesenchymal phenotype by epithelial-mesenchymal transition in 3 weeks of OSE culture. Germ cell markers like c-Kit, DAZL, GDF-9, VASA, and ZP4 were immuno-localized in oocyte-like structures. In conclusion, as opposed to the existing view of OSE being a bipotent source of oocytes and granulosa cells, mammalian ovaries harbor distinct very small embryonic-like PSCs and tissue committed progenitor stem cells population that have the potential to develop into oocyte-like structures in vitro, whereas mesenchymal fibroblasts appear to form supporting granulosa-like somatic cells. Research at the single-cell level, including complete gene expression profiling, is required to further confirm whether postnatal oogenesis is a conserved phenomenon in adult mammals.
Cooperative transport of extended payloads (2006)

In this paper we present experimental results for the dual robot transport of an extended payload. Two robotic rovers that were designed specifically for the extended payload transport task are described. Each rover incorporates a 4-DOF robot arm incorporating three active joints (one of which is a gripper), a passive wrist, and a mobile base which employs a rocker-bogie design. A set of behaviors has been developed to support the performance of the task, integrating simple sensing with controls. We describe the behaviors and their integration within the overall task structure. The experimental results presented focus on the manipulation elements of the task, but incorporate a complete cycle of pick-up, traversal, and putdown
MaxProp: Routing for Vehicle-Based Disruption-Tolerant Networks (2006)

Disruption-tolerant networks (DTNs) attempt to route network messages via intermittently connected nodes. Routing in such environments is difficult because peers have little information about the state of the partitioned network and transfer opportunities between peers are of limited duration. In this paper, we propose MaxProp, a protocol for effective routing of DTN messages. MaxProp is based on prioritizing both the schedule of packets transmitted to other peers and the schedule of packets to be dropped. These priorities are based on the path likelihoods to peers according to historical data and also on several complementary mechanisms, including acknowledgments, a head-start for new packets, and lists of previous intermediaries. Our evaluations show that MaxProp performs better than protocols that have access to an oracle that knows the schedule of meetings between peers. Our evaluations are based on 60 days of traces from a real DTN network we have deployed on 30 buses. Our network, called UMassDieselNet, serves a large geographic area between five colleges. We also evaluate MaxProp on simulated topologies and show it performs well in a wide variety of DTN environments.
Attribute-Guided Face Generation Using Conditional CycleGAN (2017)

We are interested in attribute-guided face generation: given a low-res face input image, an attribute vector that can be extracted from a high-res image (attribute image), our new method generates a high-res face image for the low-res input that satisfies the given attributes. To address this problem, we condition the CycleGAN and propose conditional CycleGAN, which is designed to 1) handle unpaired training data because the training low/high-res and high-res attribute images may not necessarily align with each other, and to 2) allow easy control of the appearance of the generated face via the input attributes. We demonstrate impressive results on the attribute-guided conditional CycleGAN, which can synthesize realistic face images with appearance easily controlled by user-supplied attributes (e.g., gender, makeup, hair color, eyeglasses). Using the attribute image as identity to produce the corresponding conditional vector and by incorporating a face verification network, the attribute-guided network becomes the identity-guided conditional CycleGAN which produces impressive and interesting results on identity transfer. We demonstrate three applications on identity-guided conditional CycleGAN: identity-preserving face superresolution, face swapping, and frontal face generation, which consistently show the advantage of our new method.
<i>Escherichia coli</i>K1 Capsular Polysaccharide Associated with Neonatal Meningitis (1974)

Examination of 77 strains of Escherichia coli from the cerebrospinal fluid of neonates with meningitis revealed 65 (84 per cent) with the capsular (K1) polysaccharide. The Esch. coli K1 capsular antigen has been shown to be immunochemically identical to the meningococcal Group B polysaccharide. These cerebrospinal-fluid Esch. coli K1 strains were associated with at least seven different somatic (O) and three flagella (H) antigens. In contrast, Esch. coli K1 strains were found in 14 of 36 (39 per cent) blood cultures of neonates without meningitis and in approximately 15 per cent of blood, urine and stool cultures from adults and rectal cultures from infants. The mean median lethal dose in a mucin-enhanced mouse model for 31 neonatal cerebrospinal-fluid K1 isolates was 168 organisms. In contrast, the median lethal dose for 10 neonatal non-K1 isolates was 58,000 and was greater than 10,000 organisms for six non-K1 enteropathogenic strains and five K1 strains isolated from normal infant stools. The high prevalence of the K1 antigen in neonatal meningitis suggests that this capsular polysaccharide is related to Esch. coli invasiveness in the newborn. A protective effect of anti-capsular antibody in a mouse model suggests that immunity to neonatal Esch. coli K1 meningitis may be mediated by serum antibodies. (N Engl J Med 290:1216–1220, 1974)
Electrophysiological and in vivo characterization of A-317567, a novel blocker of acid sensing ion channels (2005)

Acid Sensing Ion Channels (ASICs) are a group of sodium-selective ion channels that are activated by low extracellular pH. The role of ASIC in disease states remains unclear partly due to the lack of selective pharmacological agents. In this report, we describe the effects of A-317567, a novel non-amiloride blocker, on three distinct types of native ASIC currents evoked in acutely dissociated adult rat dorsal root ganglion (DRG) neurons. A-317567 produced concentration-dependent inhibition of all pH 4.5-evoked ASIC currents with an IC50 ranging between 2 and 30muM, depending upon the type of ASIC current activated. Unlike amiloride, A-317567 equipotently blocked the sustained phase of ASIC3-like current, a biphasic current akin to cloned ASIC3, which is predominant in DRG. When evaluated in the rat Complete Freud's Adjuvant (CFA)-induced inflammatory thermal hyperalgesia model, A-317567 was fully efficacious at a dose 10-fold lower than amiloride. A-317567 was also potent and fully efficacious when tested in the skin incision model of post-operative pain. A-317567 was entirely devoid of any diuresis or natriuresis activity and showed minimal brain penetration. In summary, A-317567 is the first reported small molecule non-amiloride blocker of ASIC that is peripherally active and is more potent than amiloride in vitro and in vivo pain models. The discovery of A-317567 will greatly help to enhance our understanding of the physiological and pathophysiological role of ASICs.
Surface morphology and deuterium retention of tungsten after low- and high-flux deuterium plasma exposure (2014)

The surface morphology and deuterium retention were investigated of polycrystalline tungsten targets that were exposed to deuterium plasmas at widely varying conditions. By changing only one parameter at a time, the isolated effects of flux, time and pre-damaging on surface modifications and deuterium retention were studied. The sample exposed to low-flux plasma (10(20) m(-2)s(-1)) is mostly smooth with only a few areas containing very large blisters (50-500 m). The samples exposed to high-flux plasmas (10(24) m(-2)s(-1)) show large numbers of smaller blisters (1-10 m) and in addition even smaller protrusions (<750 nm). The size of the blisters and their density strongly increase with fluence. Pre-damaging tungsten with MeV ions leads to less blisters but to more protrusions. In addition to these (sub-) micrometer-sized structures, all samples show formation of nanostructures. Comparison of a low-flux and high-flux sample exposed to similar fluence showed that the variation in morphology is dominated by the flux differences. It is shown that the blisters and protrusions originate in inter-and intra-granular cavities, respectively. The depth of the cavities underneath the surface correlates well with the depth distributions of the retained deuterium. Trapping of significant amounts of deuterium therefore seems to take place in and/or close to these cavities and gives rise to an additional peak in the thermal desorption spectrum at 700 K.
Electrical and structural properties of AlN/GaN and AlGaN/GaN heterojunctions (2008)

The electrical and structural properties of AlN/GaN heterostructures grown by molecular beam epitaxy on sapphire are compared with those of AlGaN/GaN heterostructures. The structural characteristics as assessed by x-ray diffraction show little difference but the electron density in the two-dimensional electron gas is about twice higher for AlN/GaN structures with only slightly lower mobility than in AlGaN/GaN. By proper choice of the Fe doping in GaN(Fe) and the thickness of unintentionally doped GaN layers, the composite buffer of the structure can be made semi-insulating. The current through the AlN/GaN structures is determined by tunneling through the AlN barrier and is much higher than that for AlGaN/GaN films due to the lower thickness of AlN compared to AlGaN. Increasing the thickness of AlN from 3 to 4 nm decreases the leakage current by about an order of magnitude.
Closthioamide: An Unprecedented Polythioamide Antibiotic from the Strictly Anaerobic Bacterium <i>Clostridium cellulolyticum</i> (2010)

Run-Time Reconfigurable System-on-Chip (2006)

This paper introduces a novel architecture that is targeted for adaptive embedded system applications, such as telerobotics, space navigation and wireless hot-spot access points. All these applications consist of static (i.e. known) hard and soft realtime constraints, as well as dynamic (i.e. unknown and unpredictable) environment conditions, hence require the predictability of fixed hardware resources, along with the adaptability of programmable hardware devices. The proposed embedded system consists of a soft-core fixed microprocessor and a reconfigurable co-processor. The latter utilizes Run-Time Reconfiguration (RTR) functionality in order to respond to the changing environment inputs, while the former guarantees meeting soft and hard deadlines in order to achieve the intended system functionality. The Reconfigurable Processor Unit (RPU) allows for the simultaneous execution of multiple hardware functional units, by exploiting a Just-In-Time (JIT) compiler in order to maintain hardware and software flow synchronization. However, the JIT compiler description is outside the scope of this paper
Medicinal chemical studies on antiplasmin drugs. VII. Oxa analogs of 4-aminomethylcyclohexanecarboxylic acid. (1980)

The two isomers of 5-aminomethyltetrahydro-2H-pyran-2-carboxylic acid (9) and those of 5-aminomethyl-1, 4-dioxane-2-carboxylic acid (18) were synthesized from 2-ethoxycarbonyl-3, 4-dihydro-2H-pyran-5-carboxylic acid chloride (2) and dimethyl 1, 4-dioxane-2, 5-dicarboxylate (15), respectively. From the aminoacetal (19) and dimethyl bis (hydroxymethyl) malonate (21), trans-2-aminomethyl-1, 3-dioxane-5-carboxylic acid (26A) was synthesized. The configurations of these isomers were determined on the basis of their nuclear magnetic resonance spectra, and the preferred conformations of the isomers in aqueous solution were similarly deduced. No compound showed antiplasmin activity more potent than that of trans-4-aminomethylcyclohexanecarboxylic acid (1A).
Speech emotion recognition using multichannel parallel convolutional recurrent neural networks based on gammatone auditory filterbank (2017)

Speech Emotion Recognition (SER) using deep learning methods based on computational auditory models of human auditory system is a new way to identify emotional state. In this paper, we propose to utilize multichannel parallel convolutional recurrent neural networks (MPCRNN) to extract salient features based on Gammatone auditory filterbank from raw waveform and reveal that this method is effective for speech emotion recognition. We first divide the speech signal into segments, and then get multichannel data using Gammatone auditory filterbank, which is used as a first stage before applying MPCRNN to get the most relevant features for emotion recognition from speech. We subsequently obtain emotion state probability distribution for each speech segment. Eventually, utterance-level features are constructed from segment-level probability distributions and fed into support vector machine (SVM) to identify the emotions. According to the experimental results, speech emotion features can be effectively learned utilizing the proposed deep learning approach based on Gammatone auditory filterbank.

The Jamaican Setting (1973)

In some respects Jamaica, like the rest of the British Caribbean, is regarded as being part of western industrialised society. At the same time it is a developing, or under-developed country, with tremendous social problems, and its own peculiarities of life and culture, providing a unique social setting within which its adolescents must grow up.
EGFR family: Structure physiology signalling and therapeutic targets <sup>†</sup> (2008)

There are four members of the EGFR family: EGFR, erbB2, erbB3 and erbB4. These receptors form ligand-activated oligomers which regulate intracellular processes via an oligomeric tyrosine kinase scaffold. The receptors are activated when the extracellular domain undergoes a conformational change which facilitates either homo- or hetero-oligomerization with other family members. The absence of one EGFR family member leads to embryonic or early post-natal death due to implantation, central nervous system or cardiac defects. Many mouse models of defective or deficient EGFR family members are available for studying physiology and/or pathology of EGFR family members. Sophisticated antibody and kinase inhibitors which target different family members have been designed, produced. EGFR and erbB2 are frequently activated, over expressed or mutated in many common cancers and the antagonists and/or inhibitors of EGFR and/or erbB2 signalling have already been shown to have therapeutic benefits for cancer patients.
Silicon nanorods / P3HT hybrid solar cells (2009)

Vertically oriented Si nanorods (SiNRs) grown on different substrates were successfully obtained by hot wire chemical vapor deposition (HWCVD) with the glancing angle incident silane flux. The organic-inorganic hybrid solar cells were fabricated by spin coating 3-hexylthiophene (P3HT) into the SiNRs array with the average length of ~200 nm and average separation of ~10 nm. The P3HT shows well penetration into the SiNRs. The materials and the devices were characterized by the absorption and photoluminescence (PL) spectra. The PL peak intensity of P3HT decreased after P3HT penetrating into SiNRs, which probably is due to the charge transfer between the SiNRs and P3HT and the interfacial recombination of carriers. The best hybrid solar cell to-date shows a power conversion efficiency of 0.2% under AM 1.5 illumination for the active area of 1 cm × 1 cm.
