Development of Ergonomic Balance Seat(e-BASE) Chair (2013)

Objective: The aim of this study is to develop an ergonomic office chair that has an alarm function for the unbalanced sitting postures. Background: Contrary to expectation, it is reported that office workers sit on their chairs much more in unbalanced postures during daily work. Even though an office worker uses an ergonomically good-designed chair and begins their work in a good sitting posture, his/her posture is likely to shift to the unbalanced bad posture. Therefore, a posture alarm system would be very helpful in keeping office workers" good postures. Method: We developed a prototype chair with four load cells under a seat pan and one load cell beneath a backrest. Through some experiments, we set the criteria for unbalanced bad postures then implemented the criteria into the alarm system of the prototype chair. The chair called e-BASE chair could detect unbalance postures and show alarms for chair users. We also enhanced back support by developing a step-wised folding backrest. Results: The e-BASE chair showed better performance in interface pressure distributions and balanced posture ratio in VDT work. Conclusion: The ergonomic chair with posture alarm function(e-BASE chair) was developed. It showed better performance in seat pressure distribution and in keeping good posture during office work. Application: The posture alarm system and folding backrest can be applied to the new models of office chair.

Design of Micromachined RF Switch (1999)

The switch contact design of mechanical micromachined switches on the standpoint of the tradeoff between the return loss in the "On" state and the isolation in the "Off" state is discussed. The electrical characteristics of the switch fabricated on a glass substrate were measured from 1GHz to 30GHz. Insertion loss less than 0.3dB and return loss less than -15dB at 30GHz were obtained.
Differential expression and regulation of murine CD40 in regional vascular beds (2005)

There is emerging evidence for a role of the CD40/CD40 ligand (CD40L) dyad as a signaling mechanism in different inflammatory conditions. The aims of this study were to 1) quantify the constitutive and induced expression of CD40 in different regional vascular beds of the mouse and 2) assess the role of CD40L as a modulator of vascular endothelial CD40 expression. The dual radiolabeled monoclonal antibody technique was used to quantify the expression of endothelial CD40 in control and LPS-challenged wild-type (WT) mice. Significant constitutive CD40 expression was detected in several vascular beds of WT mice with lung, kidney, and small intestine exhibiting the highest expression, whereas the liver and stomach showed no detectable baseline expression. LPS administration elicited two- to sevenfold increases in CD40 expression in several tissues (heart, kidney, and intestine) within 4 h, whereas other organs (brain) required up to 48 h to exhibit CD40 upregulation. CD40 expression was not detected in unstimulated or LPS-challenged CD40-/- mice. Constitutive expression of CD40 was profoundly reduced in unstimulated CD40L-/- mice, but the LPS-induced CD40 upregulation did not differ between CD40L-/- and WT mice. Depletion of platelets or T lymphocytes, the major CD40L-expressing cells in blood, also resulted in a profound reduction in basal CD40 expression. These findings demonstrate significant endothelial expression of CD40 under basal conditions in different vascular beds and increased CD40 expression after endothelial cell activation with LPS. Platelet- and T-lymphocyte-associated CD40L appears to play a major role in regulating the density of CD40 expression on vascular endothelial cells in vivo.
A new prescription model for regional citrate anticoagulation in therapeutic plasma exchanges (2017)

We propose a new protocol, which enables for the first time to individualize the prescription of regional citrate anticoagulation during TPE, in an efficient manner. The immediately obtained regional anticoagulation protects against both the risk of coagulation of the membrane and the exposure to an excess of citrate.
Silicon Microphotonics: Hardware for the Information Age (2006)

Summary form only given. The optical components industry stands at the threshold of a major expansion that will restructure its business processes and sustain its profitability for the next three decades. This growth will establish a cost effective platform for the partitioning of electronic and photonic functionality to extend the processing power of integrated circuits and the performance of optical communications networks. The traditional dimensional shrink approach to the scaling of microprocessor technology is encountering barriers in materials and power dissipation that dictate more distributed, parallel architectures. As short link interconnection capacity crosses the 10 Mb/s km thresholds that dictate optical carrier utilization, a high volume silicon-based platform is required. The platform enables smart partitioning of electronic and photonic signal processing to give extended functionality to silicon CMOS technology. The talk gives an overview of the evolving silicon microphotonics technology platform: materials, components and monolithic integration; and assess its ability to meet the processing, interconnection and high volume production challenges in the next phase of the information age
Ab Initio Molecular Orbital Studies of the Structure and Stability of the BeAl2F8 Complex (2009)

Ab initio molecular orbital calculations have been carried out on the 1:2 metal halide complex BeAl2F8 using a minimal basis set. Seven possible structures with different fluorine bridging combinations were considered. The most stable structure has D2d symmetry with a tetracoordinated beryllium in a tetrahedral configuration. Generally, structures with high coordination numbers for beryllium were more stable than those with low coordination numbers. A ring structure with beryllium in a trigonal configuration was also among the more favorable structures.
A single-channel noise cancelation filter in the short-time-fourier-transform domain (2016)

This paper develops a single-channel noise cancelation filter in the short-time Fourier transform (STFT) domain by combining the subspace method and the optimal filtering technique via joint diagonalization of the desired clean speech and noise signal correlation matrices. This filter is shown to be flexible in controlling the compromise between the output signal-to-noise ratio (oSNR) and the amount of speech distortion. Simulations are performed to justify the property of this filter.
Cover Feature: A New Class of Task‐Specific Imidazolium Salts and Ionic Liquids and Their Corresponding Transition‐Metal Complexes for Immobilization on Electrochemically Active Surfaces (Chem. Eur. J. 20/2022) (2022)

Task-specific polyaryl-/oligoether-substituted, imidazolium-based ionic liquids (ILs) with linker moieties enable interaction with electrochemically active surfaces. Thus, electron and proton transfer ought to be facilitated along the side chains. When used as a precursor for carbene ligands, the complex's reactivity and potential catalytic activity can be increased by interaction with an electrode. The ether functionality also enhances the catalyst's solubility, for example, in oligoether-based ILs. More information can be found in the Research Article by K. Meyer et al. (DOI: 10.1002/chem.202200100).
Cross-Frequency Power Correlations Reveal the Right Superior Temporal Gyrus as a Hub Region During Working Memory Maintenance (2011)

In the present study, we characterized within- and cross-frequency power correlations from magnetoencephalography (MEG) data in order to understand how different brain regions cooperate as a network to maintain working memory representations with several features. The working memory items were composed of spatially arranged dots supposedly requiring both the dorsal and the ventral stream to be engaged during maintenance. Using a beamforming technique, we localized memory-dependent sources in the alpha, beta, and gamma bands. After the single-trial power values were extracted from these frequency bands with respect to each source, we calculated the correlations within- and cross-frequency bands. The following general picture emerged: gamma power in right superior temporal gyrus (STG) during working memory maintenance was correlated with numerous other sources in the alpha band in prefrontal, parietal, and posterior regions. In addition, the power correlations within the alpha band showed correlations across posterior-parietal-frontal regions. From these findings, we suggest that the STG dominated by gamma activity serves as a hub region for the network nodes responsible for the retention of the stimulus used in this study, which is likely to depend on both the "where-" and the "what-" visual system simultaneously. The present study demonstrates how oscillatory dynamics reflecting the interaction between cortical areas can be investigated by means of cross-frequency power correlations in source space. This methodological framework could be of general utility when studying functional network properties of the working brain.
A novel integration of STT-MRAM for on-chip hybrid memory by utilizing non-volatility modulation (2019)

We demonstrate a novel way of integrating STT-MRAM for on-chip hybrid memory which exhibits either features of high-retention or high-speed implemented in separate zones in a single chip. For satisfying high-temperature retention requirement, tailored MTJs are shown to support > 10 year retention at 220°C. For high-speed operation, critical improvements have been made in terms of TMR, short fail probability, overdrive and write error rate. The new integration provides a manufacturable way of combining diverse memory components by modulating non-volatility of STT-MRAM without affecting within-chip distributions of critical properties.
Solid state mechanochemical processes for better electroceramics. (2014)

The present short overview focuses on the renovation of solid state processes toward phase pure and well-crystallized complex oxides centered on the electroceramic materials. Elevation of the reactivity and preservation of stoichiometry of the starting mixture or precursor are of universal importance. Mechanical activation, being considered as versatile, may also need reconsideration in view of contamination and process rationalization. After briefly reviewing mechanochemical processes for direct synthesis of complex oxides, solid state processes toward well crystallized fine particles of complex oxides are discussed by starting from mechanochemically derived precursors with subsequent optimized calcination. Case studies were cited from literatures for complex oxides, including author's own experimental studies mainly with BaBi(2)Ta(2)O(9) (BBT), Ba(Mg(1/3)Ta(2/3))O(3) (BMT) and KNbO(3) (KN). The substances discussed are mostly associated with ferroelectric materials, with a few exceptions of iron-containing magnetic materials.
Student-Teacher Training with Diverse Decision Tree Ensembles (2017)

Student-teacher training allows a large teacher model or ensemble of teachers to be compressed into a single student model, for the purpose of efficient decoding. However, current approaches in automatic speech recognition assume that the state clusters, often defined by Phonetic Decision Trees (PDT), are the same across all models. This limits the diversity that can be captured within the ensemble, and also the flexibility when selecting the complexity of the student model output. This paper examines an extension to student-teacher training that allows for the possibility of having different PDTs between teachers, and also for the student to have a different PDT from the teacher. The proposal is to train the student to emulate the logical context dependent state posteriors of the teacher, instead of the frame posteriors. This leads to a method of mapping frame posteriors from one PDT to another. This approach is evaluated on three speech recognition tasks: the Tok Pisin and Javanese low resource conversational telephone speech tasks from the IARPA Babel programme, and the HUB4 English broadcast news task.
Realtime online adaptive gesture recognition (2003)

We introduce an online adaptive algorithm for learning gesture models. By learning gesture models in an online fashion, the gesture recognition process is made more robust and the need to train on a large training ensemble is obviated. Hidden Markov models are used to represent the spatial and temporal structure of the gesture. The usual output probability distributions-typically representing appearance-are trained at runtime exploiting the temporal structure (Markov model) that is either trained off-line or is explicitly hand-coded. In the early stages of runtime adaptation, contextual information derived from the application is used to bias the expectation as to which Markov state the system is in at any given time. We describe the watch and learn system, a computer vision system which is able to learn simple gestures online for interactive control.

Quantitative trait loci associated with longevity of lettuce seeds under conventional and controlled deterioration storage conditions (2010)

Lettuce (Lactuca sativa L.) seeds have poor shelf life and exhibit thermoinhibition (fail to germinate) above ∼25°C. Seed priming (controlled hydration followed by drying) alleviates thermoinhibition by increasing the maximum germination temperature, but reduces lettuce seed longevity. Controlled deterioration (CD) or accelerated ageing storage conditions (i.e. elevated temperature and relative humidity) are used to study seed longevity and to predict potential seed lifetimes under conventional storage conditions. Seeds produced in 2002 and 2006 of a recombinant inbred line (RIL) population derived from a cross between L. sativa cv. Salinas×L. serriola accession UC96US23 were utilized to identify quantitative trait loci (QTLs) associated with seed longevity under CD and conventional storage conditions. Multiple longevity-associated QTLs were identified under both conventional and CD storage conditions for control (non-primed) and primed seeds. However, seed longevity was poorly correlated between the two storage conditions, suggesting that deterioration processes under CD conditions are not predictive of ageing in conventional storage conditions. Additionally, the same QTLs were not identified when RIL populations were grown in different years, indicating that lettuce seed longevity is strongly affected by production environment. Nonetheless, a major QTL on chromosome 4 [Seed longevity 4.1 (Slg4.1)] was responsible for almost 23% of the phenotypic variation in viability of the conventionally stored control seeds of the 2006 RIL population, with improved longevity conferred by the Salinas allele. QTL analyses may enable identification of mechanisms responsible for the sensitivity of primed seeds to CD conditions and breeding for improved seed longevity.
Surgical Correction of Prominent Ear Using Modified Tube Technique and Posterior Approach (2003)

In patients with a prominent ear, the most common deformities are a poorly developed antihelical fold and the formation of excessive conchal cartilage, particularly in the posterior conchal wall. As such, the main goal for surgical correction of a prominent ear is to narrow the conchoscaphal angle by folding the antihelix and reducing the concha. In the current study, cartilage-sparing tubing otoplasty is refined by the addition of a minimal dissection of the edge of the conchal and scaphal cartilages, and horizontal mattress sutures between the two edges. Nine patients with 13 cases were operated on between 1999 and 2001. Of the nine patients, four had bilateral procedures, and five had unilateral surgery. The age distribution was 11 to 22 years. The follow-up periods ranged from 6 months to 2 years. No hematomas or skin necrosis occurred. A mild recurrence of the upper antihelical fold was experienced in one case, and the patient required further surgery. Suture extrusions developed in two cases. In conclusion, the proposed technique is a simple and safe procedure with reliable results and no anterior scarring.
The Adhesion Modulating Properties of Tenascin-W (2012)

Tenascins are extracellular matrix glycoproteins associated with cell motility, proliferation and differentiation. Tenascin-C inhibits cell spreading by binding to fibronectin; tenascin-R and tenascin-X also have anti-adhesive properties in vitro. Here we have studied the adhesion modulating properties of the most recently characterized tenascin, tenascin-W. C2C12 cells, a murine myoblast cell line, will form broad lamellipodia with stress fibers and focal adhesion complexes after culture on fibronectin. In contrast, C2C12 cells cultured on tenascin-W fail to spread and form stress fibers or focal adhesion complexes, and instead acquire a multipolar shape with short, actin-tipped pseudopodia. The same stellate morphology is observed when C2C12 cells are cultured on a mixture of fibronectin and tenascin-W, or on fibronectin in the presence of soluble tenascin-W. Tenascin-W combined with fibronectin also inhibits the spreading of mouse embryo fibroblasts when compared with cells cultured on fibronectin alone. The similarity between the adhesion modulating effects of tenascin-W and tenascin-C in vitro led us to study the possibility of tenascin-W compensating for tenascin-C in tenascin-C knockout mice, especially during epidermal wound healing. Dermal fibroblasts harvested from a tenascin-C knockout mouse express tenascin-W, but dermal fibroblasts taken from a wild type mouse do not. However, there is no upregulation of tenascin-W in the dermis of tenascin-C knockout mice, or in the granulation tissue of skin wounds in tenascin-C knockout animals. Similarly, tenascin-X is not upregulated in early wound granulation tissue in the tenascin-C knockout mice. Thus, tenascin-W is able to inhibit cell spreading in vitro and it is upregulated in dermal fibroblasts taken from the tenascin-C knockout mouse, but neither it nor tenascin-X are likely to compensate for missing tenascin-C during wound healing.
Capacitated Beam Placement for Multi-beam Non-Geostationary Satellite Systems (2023)

Non-geostationary (NGSO) satellite communications systems have attracted a lot of attention both from industry and academia, over the past several years. Beam placement is among the major resource allocation problems in multi-beam NGSO systems. In this paper, we formulate the beam placement problem as a Euclidean disk cover optimization model. We aim at minimizing the number of placed beams while satisfying the total downlink traffic demand of targeted ground terminals without exceeding the capacity of the placed beams. We present a low-complexity deterministic annealing (DA)-based algorithm to solve the NP-hard optimization model for near-optimal solutions. We further propose an extended variant of the previous model to ensure the traffic assigned to the beams is balanced. We verify the effectiveness of our proposed methods by means of numerical experiments and show that our scheme is superior to the state-of-the-art methods in that it covers the ground users by fewer number of beams on average.
Optimal Longitudinal Slip Ratio Allocation and Control of a Hybrid Electric Vehicle With eAWD Capabilities (2016)

This paper introduces a Hybrid Electric Vehicle (HEV) with eAWD capabilities via the use of a traditional Series-Parallel hybrid transaxle at the front axle and an electric Rear Axle Drive (eRAD) unit at the rear axle. Such a vehicle requires proper wheel torque allocation to the front and rear axles in order to meet the driver demands. A model of the drivetrain is developed using Bond Graphs and is used in co-simulation with a vehicle model from the CarSim software suite for validation purposes. A longitudinal slip ratio control architecture is proposed which allocates slip ratio to the front and real axles via a simple optimization algorithm. The Youla parametrization technique is used to develop robust controllers to track the optimal slip targets generated by the slip ratio optimization algorithm. The proposed control system offers a unified approach to longitudinal vehicle control under both traction and braking events under any road surface condition. It is shown in simulation that the proposed control system can properly allocate slip ratio to the front and rear axles such that tires remain below their force saturation limits while vehicle acceleration/braking is maximized while on a low friction road surface.

A testbed for managing dynamic mixed workloads (2009)

Workload management for operational business intelligence (BI) databases is difficult. Queries vary widely in length and objectives. Resource contention is difficult to predict and to control as dynamically-arriving, long, analyst queries compete for resources with ongoing online-transaction processing (OLTP) queries and batch report queries. Currently, administrators struggle to choose workload management policies and set their thresholds manually. The goal of our project is a software framework to make the management of such mixed workloads easier. Our framework includes a policy controller that tunes workload management policies automatically to meet workload objectives. This demonstration of our system illustrates (1) the difficulty of managing a BI database workload and (2) the benefits of tuning policies automatically and individually for each service class of queries in a workload. In addition, our demonstrator is a useful research tool for understanding how policies and a policy controller adapt as the system state changes under a mixed workload. In our demo, the participant plays the administrator and tunes the policies for a variety of difficult-to-manage workloads as they execute. These policies include admission control, scheduling, and execution control policies. We visualize the policies, the user objectives, and the load on the system components (CPUs, memory, disks) during execution, which helps the participant see whether objectives are being met and make appropriate policy decisions. At the end of each workload, the participant is given the opportunity to compare how their policies met workload objectives versus policies determined by our automatic policy controller.
