Fast, reliable head tracking under varying illumination: an approach based on registration of texture-mapped 3D models (2000)

A technique for 3D head tracking under varying illumination is proposed. The head is modeled as a texture mapped cylinder. Tracking is formulated as an image registration problem in the cylinder's texture map image. The resulting dynamic texture map provides a stabilized view of the face that can be used as input to many existing 2D techniques for face recognition, facial expressions analysis, lip reading, and eye tracking. To solve the registration problem with lighting variation and head motion, the residual registration error is modeled as a linear combination of texture warping templates and orthogonal illumination templates. Fast stable online tracking is achieved via regularized weighted least-squares error minimization. The regularization tends to limit potential ambiguities that arise in the warping and illumination templates. It enables stable tracking over extended sequences. Tracking does not require a precise initial model fit; the system is initialized automatically using a simple 2D face detector. It is assumed that the target is facing the camera in the first frame. The formulation uses texture mapping hardware. The nonoptimized implementation runs at about 15 frames per second on a SGI O2 graphic workstation. Extensive experiments evaluating the effectiveness of the formulation are reported. The sensitivity of the technique to illumination, regularization parameters, errors in the initial positioning, and internal camera parameters are analyzed. Examples and applications of tracking are reported.
Comparison of conventional and collapse-mode CMUT in 1-D array configuration (2011)

This paper presents a comparison between two types of capacitive micromachined transducers (CMUTs), one operating in the conventional mode and the other one in the collapse-mode. Both types of devices are designed to have the same membrane properties (silicon, 1-μm thick), the same peak frequency (10 MHz) and similar operating bias voltages (100 V - 130 V). In the finite element analysis (FEA) of transmit pressure, both types of devices have similar fractional bandwidth (FBW) more than 120%, whereas, the collapse-mode CMUT has higher output pressure (46.5 kPa/V) than that of the conventional CMUT (13.1 kPa/V). To validate the FEA results, these two devices are fabricated using LOCOS/wafer-bonding process. The fabricated devices have a phased array configuration with an element pitch of 75 μm. The output pressure and the FBW of the conventional CMUT is 110% and 12.7 kPa/V, respectively, which match well with FEA results. The collapse-mode CMUT has a FBW of 102.5% and output pressure of 26.4 kPa/V. With a large AC excitation and high DC bias, the conventional CMUT has an output pressure of 1.25 MPa <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p-p</sub> with 56.4-V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p-p</sub> AC and 180-V DC.

Antibodies to adult t‐cell leukemia‐virus‐associated antigen (atla) in sera from patients with atl and controls in japan: A nation‐wide sero‐epidemiologic study (1982)

Abstract A nation‐wide sero‐epidemiologic survey of adult T‐cell leukemia virus (ATLV), detected es anti‐ATLA (ATLV‐associated antigen), was made in Japan. Sera from adult donors in 15 different locations were screened for anti‐ATLA. High incidences (6 to 37%) of antibody‐positive donors were found in seven regions, one in northern Japan, and the others in southwestern regions. These areas are ATLV‐endemic areas corresponding to ATL‐endemic areas. Examination of sera from healthy donors aged 6 to 80 years in ATL‐endemic areas showed an age‐dependent increase of seropositive donors with a maximum of about 30% at 40 years of age. Anti‐ATLA was found in all but two of 142 patients with ATL Anti‐ATLA‐positive patients with ATL were mainly found in ATLV‐endemic areas, and only a few in ATL‐nonendemic areas. Six patients with cutaneous T‐cell lymphoma in ATLV‐nonendemic areas gave a negative reaction for anti‐ATLA. The geometric mean titer of anti‐ATLA of patients with ATL was higher than that of healthy donors.

The GA motif: An RNA element common to bacterial antitermination systems, rRNA, and eukaryotic RNAs (2001)

Two different transcription termination control mechanisms, the T box and S box systems, are used to regulate transcription of many bacterial aminoacyl-tRNA synthetase, amino acid biosynthesis, and amino acid transport genes. Both of these regulatory mechanisms involve an untranslated mRNA leader region capable of adopting alternate structural conformations that result in transcription termination or transcription elongation into the downstream region. Comparative analyses revealed a small RNA secondary structural element, designated the GA motif, that is highly conserved in both T box and S box leader sequences. The motif consists of two short helices separated by an asymmetric internal loop, with highly conserved GA dinucleotide sequences on either side of the internal loop. Site-directed mutagenesis of this motif in model T and S box leader sequences indicated that it is essential for transcriptional regulation in both systems. This motif is similar to the binding site of yeast ribosomal protein L30, the Snu13p binding sites found in U4 snRNA and box C/D snoRNAs, and two elements in 23S rRNA.
The Cucurbit[<i>n</i>]uril Family (2005)

In 1981, the macrocyclic methylene-bridged glycoluril hexamer (CB[6]) was dubbed "cucurbituril" by Mock and co-workers because of its resemblance to the most prominent member of the cucurbitaceae family of plants--the pumpkin. In the intervening years, the fundamental binding properties of CB[6]-high affinity, highly selective, and constrictive binding interactions--have been delineated by the pioneering work of the research groups of Mock, Kim, and Buschmann, and has led to their applications in waste-water remediation, as artificial enzymes, and as molecular switches. More recently, the cucurbit[n]uril family has grown to include homologues (CB[5]-CB[10]), derivatives, congeners, and analogues whose sizes span and exceed the range available with the alpha-, beta-, and gamma-cyclodextrins. Their shapes, solubility, and chemical functionality may now be tailored by synthetic chemistry to play a central role in molecular recognition, self-assembly, and nanotechnology. This Review focuses on the synthesis, recognition properties, and applications of these unique macrocycles.
Root of trust for trusted node based-on ARM11 platform (2011)

As wireless sensor network (WSN) becomes more popular in environmental, business and military applications, security issues emerge with critical concerns because it is exposed to various types of physical attacks. The key factor for preventing from physical attacks is the security they provide at the platform level. A promising approach for providing a high-level security is by a trusted boot process; constructing a chain of trust just after the platform is booted-up. This paper presents a root of trust (ROT) at the 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> level boot-up platform to construct a chain of trust at the hardware layer using an embedded secured ROM inside the processor. This platform uses one of the most popular verification algorithms as part of the 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> level boot process. It was found that the proposed system can support any application that needs a high speed processing power because it uses a 32-bit processor.
Self-assembled multilayers of electroactive polymers: From highly conducting transparent thin films to light emitting diodes (1995)

Layer-by-layer self-assembly has recently emerged as a most versatile means of processing conjugated polymers into ultrathin films with unprecedented control over thicknesses and molecular architectures. Multilayer heterostructures have been designed and fabricated from various combinations of conjugated polyions, p-type conducting polymers, sulfonated fullerenes, conjugated polymer precursors, molecular dyes, and a variety of nonconjugated polyions to study properties unique to the supramolecular organizations created. In this paper, we use layer-by-layer self-assembly to fabricate extremely thin, highly conductive films of p-doped conjugated polymers such as polypyrrole and polyaniline. Also complex multilayer heterostructures based on polyphenylene vinylene (PPV) are fabricated to study the intermolecular interactions between the PPV and other components of the film which give rise to {open_quotes}tunable{close_quotes} photoluminescence behavior. Finally, thin film light-emitting devices based on self-assembled PPV active layers are presented.
Mechanism of oxidation at a copper–polyethylene interface. II. Penetration of copper ions in the polyethylene matrix (1976)

Abstract Two surface analysis techniques (Rutherford backscattering and surface composition by analysis of neutral and ion impact radiation) have been applied to the study of interfacial copper transport in the oxidation of polyethylene films over copper surfaces. Analysis of films oxidized several thousand hours at 40, 57, and 87°C shows maximum concentrations of copper species in the polymer matrix of ∼0.1 M extending to depths of several thousand angstroms. These results, together with previous infrared spectroscopic studies, allow some significant conclusions and hypotheses to be drawn as regards the roles of heterogeneous and homogeneous catalytic processes which occur in the thermal‐oxidative degradation of polyethylene–copper systems.
Understanding the Relationship Between Brain Gene Expression and Social Behavior: Lessons from the Honey Bee (2012)

Behavior is a complex phenotype that is plastic and evolutionarily labile. The advent of genomics has revolutionized the field of behavioral genetics by providing tools to quantify the dynamic nature of brain gene expression in relation to behavioral output. The honey bee Apis mellifera provides an excellent platform for investigating the relationship between brain gene expression and behavior given both the remarkable behavioral repertoire expressed by members of its intricate society and the degree to which behavior is influenced by heredity and the social environment. Here, we review a linked series of studies that assayed changes in honey bee brain transcriptomes associated with natural and experimentally induced changes in behavioral state. These experiments demonstrate that brain gene expression is closely linked with behavior, that changes in brain gene expression mediate changes in behavior, and that the association between specific genes and behavior exists over multiple timescales, from physiological to evolutionary.
Retrieval of mandarin broadcast news using spoken queries (2000)

Considering the monosyllabic structure of the Chinese language, a whole class of indexing features for retrieval of Mandarin broadcast news using syllable-level statistical characteristics has been previously investigated. This paper presents the improvements achieved over the previous results. The major differences are: (1) Multi-scale characterand word-level indexing terms have been integrated with the syllable-level information. (2) Information cues from the contemporary newswire text corpus have been used to create more accurate syllable indexing terms. (3) Automatic document expansion, blind relevance feedback, and query expansion via the term association matrix have been applied in retrieval. With all these schemes, the average precision can be improved from 55.46% to 71.29%.
PERSISTENT CONDUCTION DEFECTS FOLLOWING DIPHTHERIA (1939)

Whether diphtheria commonly causes any permanent cardiac damage has long been the subject of discussion; but it is generally accepted that the per- sistence of electrocardiographic changes of any serious significance is extremely rare (Alstead, 1933 ; Beer, 1936 ; Begg, 1937 ; Hoskin, 1926 ; Jones and White, 1927; and Thompson, Golden, and White, 1937). It is not uncommon for complete heart block and bundle branch block to develop during the course of severe diphtheria, usually during the second week (Alstead, 1932 ; Begg, 1937 ; Franck, 1935 ; Place, 1932; and Schwensen, 1922). The mortality amongst cases showing these changes is high, but if the patient survives there is usually a complete cardiac recovery.

A Cell-Permeant Mimetic of NMN Activates SARM1 to Produce Cyclic ADP-Ribose and Induce Non-apoptotic Cell Death (2019)

SARM1, an NAD-utilizing enzyme, regulates axonal degeneration. We show that CZ-48, a cell-permeant mimetic of NMN, activated SARM1 in vitro and in cellulo to cyclize NAD and produce a Ca2+ messenger, cADPR, with similar efficiency as NMN. Knockout of NMN-adenylyltransferase elevated cellular NMN and activated SARM1 to produce cADPR, confirming NMN was its endogenous activator. Determinants for the activating effects and cell permeability of CZ-48 were identified. CZ-48 activated SARM1 via a conformational change of the auto-inhibitory domain and dimerization of its catalytic domain. SARM1 catalysis was similar to CD38, despite having no sequence similarity. Both catalyzed similar set of reactions, but SARM1 had much higher NAD-cyclizing activity, making it more efficient in elevating cADPR. CZ-48 acted selectively, activating SARM1 but inhibiting CD38. In SARM1-overexpressing cells, CZ-48 elevated cADPR, depleted NAD and ATP, and induced non-apoptotic death. CZ-48 is a specific modulator of SARM1 functions in cells.
Inductively Coupled Plasma Etching of Bulk Titanium for MEMS Applications (2005)

Titanium is a promising new material system for the bulk micromachining of microelectromechanical (MEMS) devices. Titanium-based MEMS have the potential to be used for a number of applications, including those which require high fracture toughness or biocompatibility. The bulk titanium etch rate, mask etch rate, and surface roughness in an inductively coupled plasma (ICP) as a function of various process parameters are presented. Optimized conditions are then used to develop the titanium ICP deep etch (TIDE) process. The TIDE process is capable of producing high aspect ratio structures with smooth sidewalls at etch rates in excess of , providing a new means for the microfabrication of titanium-based MEMS devices.
High-Temperature Single Photon Detection Performance of 4H-SiC Avalanche Photodiodes (2014)

In this letter, the high-temperature performance of 4H-SiC avalanche photodiodes (APDs) working in Geiger mode is studied for the first time. At unity gain bias, the maximum quantum efficiency of the APD increases from 53.4% at 290 nm to 63.3% at 295 nm as temperature rises from room temperature to 150 °C. Meanwhile, the dark current of the APD before breakdown increases by more than two to three orders of magnitude. At a fixed gain of 1.3 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> , the single photon counting efficiency at 280 nm only slightly drops from 6.17% to 6% in the same temperature range, whereas the dark count rate increases from 22 to 80 KHz. This letter indicates that SiC APDs have the potential to work in a high-temperature harsh environment with single photon counting capability.
Bilateral Concurrent Eye Examination with a Head-Mounted Perimeter for Diagnosing Functional Visual Loss (2016)

The authors here report a case series where bilateral concurrent eye examination, using a head-mounted perimeter (imo®), was employed to facilitate diagnosis of functional visual loss, as regular ophthalmological tests were ineffective. Subjects (11-year-old female, 15-year-old male, and 24-year-old male) were diagnosed with unilateral functional visual loss by using the imo®, at the Kitasato University hospital. The results of the imo® and those of Goldmann perimetry or Humphrey Field Analyzer II differed for all subjects, which is indicative of potential functional visual loss. Bilateral concurrent examination with the imo® may become a standard for future diagnosis of unilateral functional visual loss.
SCENARIO DISCOVERY WORKFLOW FOR ROBUST PETROLEUM RESERVOIR DEVELOPMENT UNDER UNCERTAINTY (2016)

Subsurface uncertainty creates large economic risks for the development of hydrocarbon reservoirs, driving the need for a decision-making procedure that is robust with respect to this uncertainty. In current practice, decisions are often made based on a single geologic scenario, and uncertainty is modeled in terms of parametric variations around best-estimate values within that scenario. In such a procedure, the impact of other possible geological scenarios upon the performance of a development plan is not explicitly evaluated. To improve decision making, reservoir models with different geological concepts (e.g., different environments of deposition) should be built to capture the full range of uncertainty. However, it is difficult to analyze the results from many models and provide summary information pertinent to business needs. In this paper, a scenario discovery-based outcome analysis workflow is described to systematically explore the result of many (50 to 10,000 or more) reservoir simulation runs. The workflow includes defining performance metrics to reflect business needs, exploring and defining outcome scenarios, searching for relationships between geological parameters and outcomes, and selecting and investigating individual representative cases. Supported by various data mining and data visualization techniques, this workflow may help decision-makers to better understand the potential business impacts of the uncertainty and develop insights concerning geological parameters that control these impacts. We present two examples of this workflow based on a subset of the SAIGUP [Manzocchi et al., Petrol. Geosci., 141(1):3−15, 2008] dataset containing 2268 reservoir simulation models, from a full factorial combination of four sedimentology parameters and three structural parameters. In the first example, we examine the shape of production profiles, demonstrating the identification of geological origins for different shapes of production curves using only a small fraction of the full factorial simulation set. In the second example, we analyze the factors influencing water breakthrough time. For both examples, we identify representative reservoir models to ground decision-making in concrete instances.
Effects of Grip-Force, Contact, and Acceleration Feedback on a Teleoperated Pick-and-Place Task (2016)

The multifaceted human sense of touch is fundamental to direct manipulation, but technical challenges prevent most teleoperation systems from providing even a single modality of haptic feedback, such as force feedback. This paper postulates that ungrounded grip-force, fingertip-contact-and-pressure, and high-frequency acceleration haptic feedback will improve human performance of a teleoperated pick-and-place task. Thirty subjects used a teleoperation system consisting of a haptic device worn on the subject's right hand, a remote PR2 humanoid robot, and a Vicon motion capture system to move an object to a target location. Each subject completed the pick-and-place task 10 times under each of the eight haptic conditions obtained by turning on and off grip-force feedback, contact feedback, and acceleration feedback. To understand how object stiffness affects the utility of the feedback, half of the subjects completed the task with a flexible plastic cup, and the others used a rigid plastic block. The results indicate that the addition of grip-force feedback with gain switching enables subjects to hold both the flexible and rigid objects more stably, and it also allowed subjects who manipulated the rigid block to hold the object more delicately and to better control the motion of the remote robot's hand. Contact feedback improved the ability of subjects who manipulated the flexible cup to move the robot's arm in space, but it deteriorated this ability for subjects who manipulated the rigid block. Contact feedback also caused subjects to hold the flexible cup less stably, but the rigid block more securely. Finally, adding acceleration feedback slightly improved the subject's performance when setting the object down, as originally hypothesized; interestingly, it also allowed subjects to feel vibrations produced by the robot's motion, causing them to be more careful when completing the task. This study supports the utility of grip-force and high-frequency acceleration feedback in teleoperation systems and motivates further improvements to fingertip-contact-and-pressure feedback.
