Comparison of three implementations of HeadTurn: a multimodal interaction technique with gaze and head turns (2016)

The best way to construct user interfaces for smart glasses is not yet known. We investigated the use of eye tracking in this context in two experiments. The eye and head movements were combined so that one can select the object to interact by looking at it and then change a setting in that object by turning the head horizontally. We compared three different techniques for mapping the head turn to scrolling a list of numbers with and without haptic feedback. We found that the haptic feedback had no noticeable effect in objective metrics, but it sometimes improved user experience. Direct mapping of head orientation to list position is fast and easy to understand, but the signal-to-noise ratio of eye and head position measurement limits the possible range. The technique with constant rate of change after crossing the head angle threshold was simple and functional, but slow when the rate of change is adjusted to suit beginners. Finally the rate of change dependent on the head angle tends to lead to fairly long task completion times, although in theory it offers a good combination of speed and accuracy.
Development of a Hand-Eye System for Random Picking Tasks (2015)

In this paper, we introduce the bin-picking robot system we developed for the manufacturing industry. The system, that is composed of RGB-D cameras and a dual-arm robot, should locate the target object inside a bin, pick it, and place it onto the assembly jig. As target objects, three types of pipes and two types of flat plates (all of them made of metal) were used. To estimate the position and pose of an object inside the bin, the depth image captured by the RGB-D camera is used. And we describe three evaluation methods; accuracy, reproducibility and availability, those applied for an object's position and pose estimation algorithm, too. The accuracy and the reproducibility of the estimation are evaluated using an XYθ stage. The object is transferred in X and Y directions and rotated about Z axis using the stage, and the estimated transfer matrix of each location is compared to the real one. The availability for the estimation algorithm is measured by simulating the manipulation task with human operation. The results of the estimation agree with the manipulation experiments performed on the robot.

Effects of Mindful Eating and YogaDance among Overweight and Obese Women: An Exploratory Randomized Controlled Trial (2023)

Many current treatment options for managing overweight and obesity consist of rather strict diet and exercise regimes that are difficult to implement as a lifelong routine. Therefore, alternative initiatives such as mindful eating and pleasure-oriented physical activity with more focus on implementation and enjoyment are needed to reverse the obesity epidemic. Mindful eating is an approach focusing on inner hunger and satiety signals. YogaDance is a novel exercise approach combining elements of yoga and dance. This study was a randomized controlled trial investigating the individual and combined effects of mindful eating and YogaDance. Participants were healthy, inactive women with overweight or obesity (body mass index ≥ 25 kg/m<sup>2</sup> and/or waist circumference ≥ 80 cm) who were randomized to one of four groups for 8 weeks: mindful eating alone, YogaDance alone, the combination of mindful eating and YogaDance, or control. Fat mass was the primary outcome and secondary outcomes included body weight, waist circumference, and other physiological, behavioral, and quality-of-life outcomes. Sixty-one women were included in the study and randomized to mindful eating and YogaDance combined, YogaDance, mindful eating, or control. Fat mass was reduced by 1.3 kg (95% CI [-10.0, 7.3] kg; <i>p</i> = 0.77), 3.0 kg (95% CI [-11.1, 5.1] kg; <i>p</i> = 0.48), and 1.8 kg (95% CI [-10.1, 6.6] kg; <i>p</i> = 0.69) for the mindful eating, YogaDance, and combined mindful eating and YogaDance interventions, respectively, compared to the control, with corresponding effect sizes of 0.15, 0.34, and 0.21. In complete-case analyses, fat percent and waist circumference were reduced whereas mental quality of life and eating behavior were improved for mindful eating and mindful eating and YogaDance combined compared to the control. In conclusion, the study found modest benefits of an 8-week combination of mindful eating and YogaDance, corroborating findings in previous studies on mindful eating, yoga, and dance. However, the study had several limitations that should be taken into consideration, including low power due to a large drop-out as well as low to moderate training load and compliance. The trial was retrospectively registered (ISRCTN87234794).
Epoxy Resins: Effect of Amines on Curing Characteristics and Properties (1986)

The effect of orientation of amino group (i.e. m-DDS and p-DDS) and concentration of diamine (10 phr-50 phr) on the curing of diglycidyl ether of bisphenol-A (DGEBA) was investigated. Heat of polymerization (ΔH) increased with increasing phr of diamines up to optimum phr (37.19). Further increase in amine concentration of m-DDS to 50 phr re duced ΔH while in p-DDS, a steady increase was noted. m-DDS was more reactive than p-DDS as a curator of DGEBA. Thermal stability of cured resins depended on the concen tration of diamine. A Two-step decomposition was observed at low phr (&lt;20) of diamine. Mechanical properties of glass fabric reinforced epoxy laminates cured by p-DDS were slightly better than those cured by m-DDS. A significant improvement in strength was observed by addition of 3 phr of amine terminated acrylonitrile butadiene copolymer (ATBN). Rubber toughened laminates showed a poor retention of strength on thermal age ing and boiling water treatment.

Human Nature (1999)

Abstract As I am writing this column, the Melissa Virus has just passed as the media computer crisis du jour. The federal authorities have arrested a New Jersey man as the prime suspect and he is currently out on bond. Details are just now starting to be revealed detailing just how this person was identified. All of this is good and I look forward to hearing and reading more. Perhaps one of you was involved in the chase and would like to write an article on how the virus writer was identified.
Pulverized-coal injection at a blast furnace with a conical charging system (2015)

The initial experience with pulverized-coal injection in two blast furnaces at OAO NLMK is analyzed. Factors affecting the pulverized-coal combustion in the tuyere are identified. The operational efficiency of the blast furnace with different pulverized-coal flow rates is discussed. Stable pulverized-coal consumption no lower than 135 kg/t has been attained at a blast furnace with a conical charging system; the corresponding furnace productivity is 70–75 t/m2 per day.
Prey-Capture Behavior in Gymnotid Electric Fish: Motion Analysis and Effects of water Conductivity (2001)

Animals can actively influence the content and quality of sensory information they acquire from the environment through the positioning of peripheral sensory surfaces. This study investigated receptor surface positioning during prey-capture behavior in weakly electric gymnotiform fish of the genus Apteronotus. Infrared video techniques and three-dimensional model-based tracking methods were used to provide quantitative information on body position and conformation as black ghost (A. albifrons) and brown ghost (A. leptorhynchus) knifefish hunted for prey (Daphnia magna) in the dark. We found that detection distance depends on the electrical conductivity of the surrounding water. Best performance was observed at low water conductivity (2.8 cm mean detection distance and 2 % miss rate at 35 microS cm(-)(1), A. albifrons) and poorest performance at high conductivity (1.5 cm mean detection distance and 11 % miss rate at 600 microS cm(-)(1), A. albifrons). The observed conductivity-dependence implies that nonvisual prey detection in Apteronotus is likely to be dominated by the electrosense over the range of water conductivities experienced by the animal in its natural environment. This result provides the first evidence for the involvement of electrosensory cues in the prey-capture behavior of gymnotids, but it leaves open the possibility that both the high-frequency (tuberous) and low-frequency (ampullary) electroreceptors may contribute. We describe an electrosensory orienting response to prey, whereby the fish rolls its body following detection to bring the prey above the dorsum. This orienting response and the spatial distribution of prey at the time of detection highlight the importance of the dorsal surface of the trunk for electrosensory signal acquisition. Finally, quantitative analysis of fish motion demonstrates that Apteronotus can adapt its trajectory to account for post-detection motion of the prey, suggesting that it uses a closed-loop adaptive tracking strategy, rather than an open-loop ballistic strike strategy, to intercept the prey.
Large-scale reorganization of the tonotopic map in mouse auditory midbrain revealed by MRI (2007)

The cortex is thought to be the primary site of sensory plasticity, particularly during development. Here, we report that large-scale reorganization of the mouse auditory midbrain tonotopic map is induced by a specific sound-rearing environment consisting of paired low- (16 kHz) and high-frequency (40 kHz) tones. To determine the potential for plasticity in the mouse auditory midbrain, we used manganese-enhanced MRI to analyze the midbrain tonotopic maps of control mice during normal development and mice reared in the two-tone (16 + 40 kHz) environment. We found that the tonotopic map emerged during the third postnatal week in normal mice. Before 3 weeks, a larger percentage of auditory midbrain responded to each of the suprathreshold test frequencies, despite the fact that the primary afferent projections are in place even before hearing onset. By 3 weeks, the midbrain tonotopic map of control mice was established, and manganese-enhanced MRI showed a clear separation between the 16- and 40-kHz responses. Two-tone rearing dramatically altered the appearance of these discrete frequency-specific responses. A significant volume of the auditory midbrain became responsive to both rearing frequencies, resulting in a large-scale reorganization of the tonotopic map. These results indicate that developmental plasticity occurs on a much greater scale than previously appreciated in the mammalian auditory midbrain.
Biological equilibration of allergen preparations: methodological aspects and reproducibility (1987)

A method for biological equilibration (BE) of allergen reference preparations using the skin-prick test (SPT) method and histamine HCl 10 mg/ml as reference substance (reference method), was evaluated. The precision was low for weals less than 10 mm2. The slope (log weal area/log concentration) of allergen and histamine did not vary significantly between investigators and allergens. The median slopes were 0.39 (n = 384) and 0.34 (n = 397), for allergen and histamine, respectively (P less than 0.01). The concentration of allergen eliciting a weal of the same size as that of histamine HCl 1 mg/ml (Chl) in the median sensitive patient, 1000 Biological Units/ml (BU/ml), did not vary significantly between clinics/geographical regions (grasses, mites and moulds). As BE is repeatable between regions, BUs estimated by this method are generally valid. A high correlation (r = 0.91, P less than 0.001) was found between the median Chl as estimated with histamine 1 and 10 mg/ml as reference substance, respectively. Thus, this reference method for BE is valid. The precision of the SPT method with histamine HCl 1 mg/ml is not as good as with 10 mg/ml, which is therefore recommended as the reference concentration.
De Novo Appearance and “Strain” Formation of Yeast Prion [PSI+] Are Regulated by the Heat-Shock Transcription Factor (2006)

Yeast prions are non-Mendelian genetic elements that are conferred by altered and self-propagating protein conformations. Such a protein conformation-based transmission is similar to that of PrP(Sc), the infectious protein responsible for prion diseases. Despite recent progress in understanding the molecular nature and epigenetic transmission of prions, the underlying mechanisms governing prion conformational switch and determining prion "strains" are not understood. We report here that the evolutionarily conserved heat-shock transcription factor (HSF) strongly influences yeast prion formation and strain determination. An hsf1 mutant lacking the amino-terminal activation domain inhibits the yeast prion [PSI+] formation whereas a mutant lacking the carboxyl-terminal activation domain promotes [PSI+] formation. Moreover, specific [PSI+] strains are preferentially formed in these mutants, demonstrating the importance of genetic makeup in determining de novo appearance of prion strains. Although these hsf1 mutants preferentially support the formation of certain [PSI+] strains, they are capable of receiving and faithfully propagating nonpreferable strains, suggesting that prion initiation and propagation are distinct processes requiring different cellular components. Our findings establish the importance of HSF in prion initiation and strain determination and imply a similar regulatory role of mammalian HSFs in the complex etiology of prion disease.
Activation of protein kinase C via phospholipase D enhances NADPH oxidase activity (2006)

Phospholipase D (PLD) is implicated in the activation of NADPH oxidase in human neutrophils by producing phosphatidic acid (PA), but the mechanisms involved are unclear. We report that activation of protein kinase C (PKC) isoforms and phosphorylation of the NADPH oxidase component p47 phox are regulated by PLD activation in human neutrophils. Also, PKC isoforms phosphorylated p47 phox in vitro and synergized with PA to activate NADPH oxidase in a cell‐free system. Enhancement by PKC was abolished by staurosporine, a protein kinase inhibitor, and use of a p47 phox mutant with six Serine‐to‐Alanine mutations (S303/304/328/345/348/379A), suggesting that phosphorylation of p47 phox on one or more of these serine residues mediates the enhancement. However, mutation of any of these residues individually did not abolish the enhancement by PKC, indicating that multiple serine residues were involved. To further elucidate the mechanism by which PA and PKC isoforms synergize for NADPH oxidase activation, we developed an ELISA binding assay to assess the effects of lipids and PKC on the interaction between flavocytochrome b 558 and p47 phox . The results showed that PA is required for the binding of flavocytochrome b 558 to p47 phox , and that PKC enhanced such binding. We conclude that PA binding and PKC‐dependent p47 phox phosphorylation synergize to release the auto‐inhibition of p47 phox , increasing binding to flavocytochrome b 558 and leading to enhanced NADPH oxidase activity.

Involvement of γ-Aminobutyric Acid (GABA) B Receptors in the Hypotensive Effect of Systemically Administered GABA in Spontaneously Hypertensive Rats (2002)

We investigated the effects of intraduodenally (i.d.) administered gamma-aminobutyric acid (GABA) on blood pressure (BP) in anesthetized spontaneously hypertensive rats (SHR) and the mechanism underlying this effect, especially the type of GABA receptor involved in the depressive effect of this amino acid. GABA (0.3 to 300 mg/kg, i.d.) caused a dose-related decrease in the BP of 9.20 +/- 3.96 to 35.0 +/- 5.34 mmHg (mean +/- S.E.M.) that lasted for 30 to 50 min. The minimum effective i.d. dose of GABA was 0.3 to 1.0 mg/kg. Results pertaining to the mechanism underlying the GABA-induced effects on BP were as follows: a) GABA did not alter the BP-related effects of exogenous noradrenaline and acetylcholine; b) pretreatment with hexamethonium decreased the GABA-induced fall in BP, and GABA tended to reduce the pressor response associated with injection of dimethyl phenylpiperazinium; and c) pretreatment with 2-hydroxysaclofen markedly reduced the GABA-induced drop in BP, whereas pretreatment with bicuculline did not. In conclusion, in SHR, low-dose (0.3 to 1.0 mg/kg, i.d.) GABA had a hypotensive effect, which may result from attenuation of sympathetic transmission through the activation of GABA(B) receptors at presynaptic or ganglionic sites.

Supporting method migration in a distributed object database system: a performance study (1996)

We describe the model and implementation of two approaches for method execution in distributed object query processing. The first approach is the traditional data migration approach in which remote data accesses (if required) are made to compose an in-memory object at the query site which is followed by method invocation on this object. The second approach of method migration allows the method execution to be migrated to a remote site where object data is locally available, or it can accessed with little cost. We present the results of our experimental studies. We use the O-Raid distributed database system in our experiments. We demonstrate how the performance of query processing can be improved using the method migration approach for method invocations on large and complex objects. Our results are applicable for operations on large distributed multimedia objects. We develop a benchmark for dynamic method execution in queries and perform measurements. The overheads in method execution using both the data migration and method migration approaches are identified and analyzed. Different network environments such as local area network (LAN), metropolitan area network (MAN), and wide area network (WAN) are considered in our experimental study. A wide area network emulator (WANCE) tool, also developed at Purdue University, is integrated with O-Raid system for emulating Internet sites in our laboratory environment. We analyze the impact of communication latencies between the distributed sites on the relative performance of these method execution strategies.
En Bloc Resection of Lacrimal Sac Tumors and Simultaneous Orbital Reconstruction (2014)

The combined sinus-orbit approach is an effective method of managing lacrimal sac tumors to achieve optimal tumor clearance from the orbit and nasal cavity. Simultaneous reconstruction of the bony defect with a contoured titanium mesh provides a fixation anchor for the medial canthal tendon and globe support and serves as a supporting platform for the lower eyelid and cheek to minimize midface collapse. Postoperative radiation is associated with skin flap breakdown and nasocutaneous fistula formation.
