Discrete-time sliding mode proximate time optimal seek control of hard disk drives (2000)

The paper presents a new proximate time optimal seek control approach with discrete-time variable structure control theory for a hard disk drive (HDD) servo. It incorporates the time optimal control idea into the time-varying sliding mode control design and derives a class of proximate time optimal control algorithms with robustness. The proposed approach provides one unified framework for both track seeking and track following controller design, it achieves smooth transition from seek control to track-following control naturally, and it eliminates the common chattering and overshoot problem as well. A systematic method is developed for the choice of controller parameters. Simulation results are demonstrated to show the robustness of the proposed method to disturbances, unmodelled dynamics and parameter variations with near time optimal performance.
Integrated Gas Sensing System of SWCNT and Cellulose Polymer Concentrator for Benzene, Toluene, and Xylenes (2016)

An integrated cellulose polymer concentrator/single-walled carbon nanotube (SWCNT) sensing system is demonstrated to detect benzene, toluene, and xylenes (BTX) vapors. The sensing system consists of functionalized cellulose as a selective concentrator disposed directly on top of a conductive SWCNT sensing layer. Functionalized cellulose concentrator (top layer) selectively adsorbs the target analyte and delivers the concentrated analyte as near as possible to the SWCNT sensing layer (bottom layer), which enables the simultaneous concentrating and sensing within a few seconds. The selectivity can be achieved by functionalizing cellulose acetate with a pentafluorophenylacetyl selector that interacts strongly with the target BTX analytes. A new design of the integrated cellulose concentrator/SWCNT sensing system allows high sensitivity with limits of detection for benzene, toluene, and m-xylene vapors of 55 ppm, 19 ppm, and 14 ppm, respectively, selectivity, and fast responses (<10 s to reach equilibrium), exhibiting the potential ability for on-site, real-time sensing applications. The sensing mechanism involves the selective adsorption of analytes in the concentrator film, which in turn mediates changes in the electronic potentials at the polymer-SWCNT interface and potentially changes in the tunneling barriers between nanotubes.

High energy aluminum ion implantation using a variable energy radio frequency quadrupole implanter (1998)

A high energy aluminum ion implantation using a variable energy radio frequency quadrupole (RFQ) implanter has been studied for the fabrication of high power semiconductor devices. The implanter consists of a microwave ion source with a crucible for AlCl3 sublimation, a sector type mass separator, a magnetic quadrupole triplet, a variable energy four-rod RFQ linac as an additional accelerator, an energy analyzer, and an implantation chamber. Al2+ ions, with energies of 1.0 MeV and 0.9 MeV, are implanted into a 6-inch diameter wafer, and the depth profile and dose uniformity are measured by secondary ion mass spectroscopy and sheet resistivity, respectively. Results show that the depth profile has the desired features for the projected range, and the dose non-uniformity is 0.7%.
Mitochondrial malate dehydrogenase from the thermophilic, filamentous fungus<i>Talaromyces emersonii</i> (2004)

Mitochondrial malate dehydrogenase (m-MDH; EC 1.1.1.37), from mycelial extracts of the thermophilic, aerobic fungus Talaromyces emersonii, was purified to homogeneity by sequential hydrophobic interaction and biospecific affinity chromatography steps. Native m-MDH was a dimer with an apparent monomer mass of 35 kDa and was most active at pH 7.5 and 52 degrees C in the oxaloacetate reductase direction. Substrate specificity and kinetic studies demonstrated the strict specificity of this enzyme, and its closer similarity to vertebrate m-MDHs than homologs from invertebrate or mesophilic fungal sources. The full-length m-MDH gene and its corresponding cDNA were cloned using degenerate primers derived from the N-terminal amino acid sequence of the native protein and multiple sequence alignments from conserved regions of other m-MDH genes. The m-MDH gene is the first oxidoreductase gene cloned from T. emersonii and is the first full-length m-MDH gene isolated from a filamentous fungal species and a thermophilic eukaryote. Recombinant m-MDH was expressed in Escherichia coli, as a His-tagged protein and was purified to apparent homogeneity by metal chelate chromatography on an Ni2+-nitrilotriacetic acid matrix, at a yield of 250 mg pure protein per liter of culture. The recombinant enzyme behaved as a dimer under nondenaturing conditions. Expression of the recombinant protein was confirmed by Western blot analysis using an antibody against the His-tag. Thermal stability studies were performed with the recombinant protein to investigate if results were consistent with those obtained for the native enzyme.
Modified DNA aptamers against sweet agent aspartame (2002)

We obtained a modified DNA aptamer against sweetener, aspartame, by in vitro selection method. The modified DNA was prepared from dATP, dGTP, dCTP and a modified dTTP bearing a terminal amino group at C-5 position in place of thymidine by PCR using a hyper thermophilic DNA polymerase, KOD Dash DNA polymerase. The synthetic 102-mer DNA with a 60-mer random region was used as an initial template for the PCR. The PCR-amplified modified DNA library was applied to an aspartame-agarose column, and then the bound modified DNA was eluted from the column for the affinity chromatography selection. Repeating the procedure, we selected the modified DNA aptamer against aspartame.
(Invited) Integrating Classical Semiconductor Devices with Si/Sige Quantum Dots (2014)

As semiconductor based quantum devices scale up from single to multiple qubits there is an increasing need to integrate classical semiconductor based devices to manage and generate control signals. We discuss progress on integrating field-effect transistors with planar quantum dot devices to achieve a high throughput of device testing by creating on-chip multiplexers for our devices. Using the on-chip multiplexers we can overcome the challenge of the limited number of electrical connections available in a typical dilution refrigerator while still working at the milliKelvin temperatures necessary for quantum operations. We also discuss recent advances in device design that aim to improve the performance of Si/SiGe quantum dot-based qubits.
Economic benefits of transparent OXC networks as compared to long systems with OADMs (2004)

Quantitative analysis shows that a transparent OXC network provides only up to 5% improvements in cost savings as compared to long systems with OADMs. Other unique advantages for transparent networks need to be proven-in before they are widely adopted.

Absolute quantitation of microbiota abundance in environmental samples (2018)

Spikes can be adapted to any amplicon-specific group including rhizobia from soils, Firmicutes and Bifidobacteria from human gut or Enterobacteriaceae from food samples. Crucially, using highly complex soil samples, we show that the absolute abundance of specific groups can remain steady or increase, even when their relative abundance decreases. Thus, without absolute quantitation, the underlying pathology, physiology and ecology of microbial groups may be masked by their relative abundance.

Design of an optical system consisting of a special telecentric lens for side-scattering measurement on individual cells (2010)

The alignment and collection of side-scattered light in scattering measurement on individual cells, based on hydraulic focusing technology, is always time-consuming and troublesome. Even small errors result in a poor SNR. This paper presents an optical system including a specially designed telecentric lens to focus stray light and scattering signals. The lens has a compact structure, small distortion and aberration, and large depth of focus. Thus scattering signals can be extracted easily and effectively, even when the spatial filters are out of focus or tilted with respect to the optical axis by human error. Also, the stray light in the side direction is analyzed, and the results show good performance of this special telecentric lens. Scattering results on 4.91- and 16.32-µm polystyrene beads verify that this optical system can be well applied for side-scattering signal detection.
5.10 A 1280×720 Back-Illuminated Stacked Temporal Contrast Event-Based Vision Sensor with 4.86µm Pixels, 1.066GEPS Readout, Programmable Event-Rate Controller and Compressive Data-Formatting Pipeline (2020)

Event-based (EB) vision sensors pixel-individually detect temporal contrast exceeding a preset relative threshold [1], [2] to follow the temporal evolution of relative light changes (contrast detection, CD) and to define sampling points for frame-free pixel-level measurement of absolute intensity (exposure measurement, EM) [3], [4]. EB sensors gain popularity in high-speed low-power machine vision applications thanks to temporal precision of recorded data, inherent suppression of temporal redundancy resulting in reduced post-processing cost, and wide intra-scene dynamic range operation.
Non-Newtonian Effects on Film Formation in Grease-Lubricated Radial Lip Seals (2010)

In existing models, the only lubricant property used for predicting film thickness in radial lip seals is the (base) oil viscosity. Lubricating greases show non-Newtonian behavior, and additional normal stress components develop that may contribute to the load-carrying capacity. This study investigates the shear rheology of greases and determines whether this “normal stress effect” in grease can significantly contribute to film formation in radial lip seals. First, the rheological behavior of grease is studied in a rotary plate–plate rheometer at small gaps of 25–500 μ m up to shear rates of 5 · 10 4 s −1 . The rheology measurements are used for a rheology model that predicts the first normal stress difference in the grease. Second, a seal lip model was developed to predict the lift force generated by the normal stress effect that separates the seal from the shaft. The model results show that the load-carrying capacity depends very much on the operating conditions: lip geometry, speed, and temperature. The model predicts a lift force that is over 50% of the seal specific lip force for low-contact pressure-bearing seals. The model can easily be used in existing oil seal models and makes it possible to optimize seal design by utilizing the normal stress effect.

Education of The Forester and Specialization (1952)

It is entirely appropriate and highly opportune that the “Ames Forester” should devote this issue to the subject of forestry education. In nearly every forest region of the United States professional forestry is on the march. The owners of timberlands are becoming increasingly interested in managing their lands for the production of timber crops because there are no longer any new, large frontiers of virgin timber to which they may go after their present holdings are depleted. The professional foresters employed by these timberland owners are daily being challenged to provide technical information on timber growing that would have been considered as extremely theoretical even a decade ago. As a consequence, the owners of timberland may be said to have transferred their interest from geographical frontiers to technological and scientific frontiers. These challenges to professional foresters are basically a challenge to forestry education. Confronting every forestry faculty in the United States is the very direct and practical question: "Are the forestry students now in college being offered the sort of training which will equip them to meet the even more difficult challenges that will prevail ten and fifteen years hence when they will have reached professional maturity?''
Inhibitory Action of Auxin on Root Elongation Not Mediated by Ethylene (1989)

The inhibitory effects of indole-3-acetic acid (IAA) and 1-aminocyclopropane-1-carboxylic acid (ACC) on elongation growth of pea (Pisum sativum L.) seedling roots were investigated in relation to the effects of these compounds on ethylene production by the root tips. When added to the growth solution both compounds caused a progressively increasing inhibition of growth within the concentration range of 0.01 to 1 micromolar. However, only ACC increased ethylene production in root tips excised from the treated seedlings after 24 hours. High auxin concentrations caused a transitory increase of ethylene production during a few hours in the beginning of the treatment period, but even in 1 micromolar IAA this increase was too low to have any appreciable effect on growth. ACC, but not IAA, caused growth curvatures, typical of ethylene treatment, in the root tips. IAA caused conspicuous swelling of the root tips while ACC did not. Cobalt and silver ions reversed the growth inhibitory effects induced by ACC but did not counteract the inhibition of elongation or swelling caused by IAA. The growth effects caused by the ACC treatments were obviously due to ethylene production. We found no evidence to indicate that the growth inhibition or swelling caused by IAA is mediated by ethylene. It is concluded that the inhibitory action of IAA on root growth is caused by this auxin per se.

Theory propagation and rational-trees (2013)

SAT Modulo Theories (SMT) is the problem of determining the satisfiability of a formula in which constraints, drawn from a given constraint theory T, are composed with logical connectives. The DPLL(T) approach to SMT has risen to prominence as a technique for solving these quantifier-free problems. The key idea in DPLL(T) is to closely couple unit propagation in the propositional part of the problem with theory propagation in the constraint component. In this paper it is demonstrated how reification provides a natural way for orchestrating this in the setting of logic programming. This allows an elegant implementation of DPLL(T) solvers in Prolog. The work is motivated by a problem in reverse engineering, that of type recovery from binaries. The solution to this problem requires an SMT solver where the theory is that of rational-tree constraints, a theory not supported in off-the-shelf SMT solvers, but realised as unification in many Prolog systems. The solver is benchmarked against a number of type recovery problems, and compared against a lazy-basic SMT solver built on PicoSAT.
Gene essentiality in<i>Aspergillus fumigatus</i> (2006)

Products of essential genes of Aspergillus fumigatus are seen as potential targets for antifungal drugs, and both functional screens and bioinformatics approaches have been used to help identify such genes. The random screening approach makes use of the deletion of one copy of a gene in a diploid, and failure to recover the deletant during haploidization. In order to investigate the function of putative essential genes identified by both screening and bioinformatics approaches, the conditional promoter of the alcA gene of Aspergillus nidulans has been used. In some cases, the genes identified are not absolutely essential, but their deletion leads to slow growth. Such deletants can be recovered and cultivated for phenotypic characterization following transformation of haploid strains.

Evolution of analog circuits on field programmable transistor arrays (2002)

Evolvable Hardware (EHW) refers to HW design and self reconfiguration using evolutionary/genetic mechanisms. The paper presents an overview of some key concepts of EHW, describing also a set of selected applications. A fine-grained Field Programmable Transistor Array (FPTA) architecture for reconfigurable hardware is presented as an example of an initial effort toward evolution-oriented devices. Evolutionary experiments in simulations and with a FPTA chip in-the-loop demonstrate automatic synthesis of electronic circuits. Unconventional circuits, for which there are no textbook design guidelines, are particularly appealing to evolvable hardware. To illustrate this situation, one demonstrates here the evolution of circuits implementing parametrical connectives for fuzzy logics. In addition to synthesizing circuits for new functions, evolvable hardware can be used to preserve existing functions and achieve fault-tolerance, determining circuit configurations that circumvent the faults. In addition, we illustrate with an example how evolution can recover functionality lost due to an increase in temperature. In the particular case of space applications, these characteristics are extremely important for enabling spacecraft to survive harsh environments and to have long life.
Sorting and the hidden-surface problem (1973)

Ten years ago the task of producing hidden-surface pictures by computer seemed untractable. Courageous men pressed forward nonetheless, and today we can have quite beautiful renderings of solid objects generated by computer in remarkably short times. The pictures being produced today and the speed of the programs producing them are beyond any but the wildest dreams of ten years ago.
Low brain iron content in idiopathic restless legs syndrome patients detected by phase imaging (2013)

We have used MRI phase analysis to study brain iron content in idiopathic RLS in vivo for the first time. Our results support the hypothesis of reduced brain iron content in RLS patients, which may have an important role in the pathophysiology of the disorder.
Assembly Automation: A Management Handbook (1984)

Success in automatic assembly design and operation comes from an awareness and sensitivity to a multitude of small design details, and only Frank Riley could pack so much knowledge and experience into a practical and authoritative guide to the selection and application of automatic assembly machinery. This book provides a thorough overview of management, engineering, and machine operator considerations necessary to ensure successful specification, procurement, design, manufacture, installation, and sustained productivity of new assembly systems. Places more emphasis on how corporations can employ an integrated systems approach to automatic assembly to respond to product quality, productivity, global manufacturing competitiveness, and increasingly aggressive consumerism. Includes a vast amount of practical information about all aspects of automated assembly. Thoroughly discusses several unusual and valuable topics, including a look into the 21st Century and the emerging influence of simultaneous engineering in manufacturing.
Domain adaptation augmented by state-dependence (2003)

In the development of spoken dialog systems, domain adaptation and dialog state-dependent language model are usually researched separately. This paper proposes a new approach for domain adaptation augmented by the dialog state-dependence, which means a dialog turn based cache model decaying synchronously with the dialog state change. Through this approach it's more simple and rapid to adapt a Chinese spoken dialog system to a new task. Two different tasks, the train ticket reservation and the park guide are selected respectively as the target task in the experiments. The consistent reductions of perplexity and character error rate are observed during the adaptation.
