Low Pressure Storage for Horticultural Crops1 (1978)

Abstract Controlled atmosphere (CA) storage has proven notably successful for storing some apple cultivars and has been adopted on a wide commercial scale. However, CA storage of other crops has had variable success (39). Since the inception of CA storage, the only major innovation in storage practices with a potential broadscale application is the use of sub-atmospheric pressures (hypo-baric storage, low pressure storage, LPS). The inventor has coined the name hypobaric for this method (20). We prefer the term low pressure storage because it is less “medicinal” in implication and is readily shortened to LPS. Although LPS has been discussed in textbooks (1, 21, 71, 75), commercial use is still restricted to a few mobile vans. In the belief that LPS is technically possible on a large scale and may offer advantages over current methods, this review undertakes to examine the potential application of LPS to selected horticultural crops.

Advances in diagnosis of electrical machines through external magnetic field (2015)

Promising parameter in the analysis and diagnosis of electrical machines is the external magnetic field that can be measured in the vicinity of the machine. This variable provides an image of the internal magnetic state of the machine and it is sensitive to very small imbalances in the machine. Therefore, information about the presence of an anomaly can be found in the analysis of this field. The magnetic field is measured close to the machine by specific wound flux sensor and is analyzed considering the evolution of its spectral content in presence of stator or rotor electrical faults. The paper gives an overview of measurement methods, fault signatures, and analysis tendency in the diagnosis of rotating electrical machines using the measurement of the external magnetic field.
CMOS active pixel sensor star tracker with regional electronic shutter (1997)

A 64/spl times/64 element CMOS active pixel sensor (APS) for star tracker applications is reported. The chip features an innovative regional electronic shutter through the use of an individual pixel reset architecture. Using the regional electronic shutter, each star in the field of view can have its own integration period. This way, simultaneous capture of bright stars with dim stars is accommodated, enabling a large increase in tracker capability. The chip achieves 80 dB dynamic range, 50 e-rms read noise, low dark current, and excellent electronic shutter linearity.
Fine-tuning of biaryl dihedral angles: structural characterization of five homologous three-atom bridged biphenyls by X-ray crystallography (2005)

The homologous series of three-atom bridged biaryls comprising 5,7-dihydro-1,2,3,9,10,11-hexamethoxydibenzo[c,e]oxepine, 6,7-dihydro-1,2,3,9,10,11-hexamethoxy-6-methyl-5H-dibenzo[c,e]azepinium chloride, 5,7-dihydro-1,2,3,9,10,11-hexamethoxydibenzo[c,e]thiepine, and the 6-oxide and 6,6-dioxide derivatives of the latter have been characterized by X-ray crystal structure analysis. Within this series the endocyclic and exocyclic biaryl dihedral angles vary over 10 degrees ranges, reflecting the changing balance of intramolecular (steric, geometric) and intermolecular (crystal packing) forces, the former being potential control elements for fine-tuning the helicity of the biaryl system.
Cell isolation and culture (2013)

Cell isolation and culture are essential tools for the study of cell function. Isolated cells grown under controlled conditions can be manipulated and imaged at a level of resolution that is not possible in whole animals or even tissue explants. Recent advances have allowed for large-scale isolation and culture of primary C. elegans cells from both embryos and all four larval stages. Isolated cells can be used for single-cell profiling, electrophysiology, and high-resolution microscopy to assay cell autonomous development and behavior. This chapter describes protocols for the isolation and culture of C. elegans embryonic and larval stage cells. Our protocols describe isolation of embryonic and L1 stage cells from nematodes grown on high-density NA22 bacterial plates and isolation of L2 through L4 stage cells from nematodes grown in axenic liquid culture. Both embryonic and larval cells can be isolated from nematode populations within 3 hours and can be cultured for several days. A primer on sterile cell culture techniques is given in the appendices.
Antistaphylococcal activity of pentamidine (1990)

Pentamidine isethionate was bacteriostatic against Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus sanguis, Micrococcus sp., and Candida albicans. S. aureus was inhibited by concentrations of 16 to 64 micrograms/ml and killed by 64 to greater than or equal to 128 micrograms/ml. Staphylococcal killing was consistently greater in the presence of cations and was unaffected by methicillin resistance.
Molecular cloning and identification of UTR1 of a yeast Saccharomyces cerevisiae as a gene encoding an NAD kinase (2001)

UTR1 of the yeast Saccharomyces cerevisiae was cloned from the genomic DNA by polymerase chain reaction and expressed in Escherichia coli. Characterization of the purified UTR1p revealed that UTR1p is a NAD kinase consisting of six identical subunits with a molecular mass of 60 kDa. UTR1p specifically phosphorylated NAD in the presence of ATP, dATP, or CTP as phosphoryl donors, and was most active at pH 8.0, 30°C. Km values of UTR1p for NAD and ATP were determined to be 0.50 mM and 0.60 mM, respectively.
Numerical calculation method for pulsed eddy-current testing (2002)

A numerical method is presented for the calculation of the time-dependent response of the interaction of a stratified plate specimen of linear conductor containing a planar flaw and an eddy-current induction coil fed by a current pulse. The flaw might be located on any sides of the layers of the plate specimen. The calculations are done with the help of Fourier-transform (FT). The time-harmonic responses of the system are calculated at properly chosen frequencies, and the obtained results are weighted by the FT of the excitation to provide the FT of the response. The results of the presented method can be used for various pulsed eddy-current testing (ECT) applications.
Tunable work function dual metal gate technology for bulk and non-bulk CMOS (2003)

This paper describes a metal gate process, which provides tunable work function values and ease of integration for dual metal gate process flow. Vertical stacks of Ru and Ta layers were subjected to high temperature anneals to promote intermixing which resulted in /spl phi//sub m/ tuning. It was found that Ru/Ta stacks provided up to 0.4 eV reduction in /spl phi//sub m/ compared to Ru. To increase this change, stacks of Ru/sub 50/Ta/sub 50//Ru were also evaluated and nearly a 0.8 eV change in /spl phi//sub m/ was observed between Ru/sub 50/Ta/sub 50//Ru and Ru/sub 50/Ta/sub 50/ electrodes.
17β-Estradiol Attenuates Acetylcholine-Induced Coronary Arterial Constriction in Women but Not Men With Coronary Heart Disease (1995)

17 beta-Estradiol modulates acetylcholine-induced coronary artery responses of female but not male atherosclerotic coronary arteries in vivo. These human data confirm reports from studies in cynomolgus monkeys that estrogen modulates the responses of atherosclerotic coronary arteries. An enhancement of endothelium-dependent relaxation by natural estrogen (as used in most hormone replacement therapy) may be important in postmenopausal women with established coronary heart disease and may contribute to the acute effect of 17 beta-estradiol on blood flow and its long-term protective effect on the development of coronary artery disease.
Quick address detection of anomalous memory cells in a flash memory test structure (1997)

A novel scheme for quick address detection of anomalous memory cells having the highest and lowest threshold voltages in a flash memory test structure is described. A test structure with a large memory cell array has been developed to evaluate reliability of flash memory cells before fabrication of a new generation of flash memory devices. In this test structure, each terminal branch of a tree-structured column selector is connected to each bitline of the array. And a simple threshold voltage distribution monitor circuit (VTDM) which we have already proposed is connected to the other end of the bitlines. A proposed Multi-Address Scanning Scheme (MASS) is performed by the tree-structured column selector with monitoring the output of VTDM. The detection time has been reduced to 1.12% in the case of 2048 columns. This novel scheme is suitable for performing reliability tests, such as program/erase endurance test and data retention test.

Control design for generator of nonlinear high frequency plasma system (2021)

This document aims to develop control systems for a generator of a nonlinear high frequency plasma system. Initial modelling was done by Advanced Energy Industries, Inc. (AE) which was passed on to Colorado State University environment for further research into developing controllers for this special model. This thesis documents all the work done by Colorado State University till Summer of 2020. The first phase of the collaboration included finding metrics for the feedback system with the nonlinear load modelled by AE. The metrics serve for better understanding of the modelling and also to generate effective control criteria suited to AE requirements. AE required for the user defined wave-forms to be tracked in an average sense without significantly changing the real time tracking criteria. This tradeoff was also addressed while developing metrics. A preliminary approach for control design was a PID controller to study its effects in a nonlinear environment. A robust control approach called H∞ loop-shaping is the primary control design developed by CSU for this specific application. The nonlinear system was approximated with a transfer function and the controller developed for that approximation. The purpose of the approximation is to generate a controller that is highly robust considering the uncertainties in high frequency plasma loads. The metrics discussed above are used for confirming the efficiency of the controllers. Controller design was the second phase of the project. Finally, in phase three, Nelder-Mead optimization was used to generalize the H∞ controller for various generator and set-point specifications. A system identification processes was also developed consisting of curve fit models for the nonlinear load. This was done with a view to the future for classifying different loads and plasma to develop customised controllers.
Magnetooptical study of Mn ions implanted in Ge (2002)

The effect of ion-implanted manganese impurities in germanium is investigated by means of Kerr effect rotation. After annealing, a magnetic cycle with a coercive field close to 3000 Oe is observed at about 10 K. The hysteresis disappears just below room temperature. The magnetic analysis, supported by structural characterization, suggests that particles rich in Mn are formed within the Ge matrix during implantation.
TRAP-Array (2006)

RAID architectures have been used for more than two decades to recover data upon disk failures. Disk failure is just one of the many causes of damaged data. Data can be damaged by virus attacks, user errors, defective software/firmware, hardware faults, and site failures. The risk of these types of data damage is far greater than disk failure with today's mature disk technology and networked information services. It has therefore become increasingly important for today's disk array to be able to recover data to any point in time when such a failure occurs. This paper presents a new disk array architecture that provides Timely Recovery to Any Point-in-time, referred to as TRAP-Array. TRAP-Array stores not only the data stripe upon a write to the array, but also the time-stamped Exclusive-ORs of successive writes to each data block. By leveraging the Exclusive-OR operations that are performed upon each block write in today's RAID4/5 controllers, TRAP does not incur noticeable performance overhead. More importantly, TRAP is able to recover data very quickly to any point-in-time upon data damage by tracing back the sequence and history of Exclusive-ORs resulting from writes. What is interesting is that TRAP architecture is amazingly space-efficient. We have implemented a prototype TRAP architecture using software at block device level and carried out extensive performance measurements using TPC-C benchmark running on Oracle and Postgress databases, TPC-W running on MySQL database, and file system benchmarks running on Linux and Windows systems. Our experiments demonstrated that TRAP is not only able to recover data to any point-in-time very quickly upon a failure but it also uses less storage space than traditional daily differential backup/snapshot. Compared to the state-of-the-art continuous data protection technologies, TRAP saves disk storage space by one to two orders of magnitude with a simple and a fast encoding algorithm. From an architecture point of view, TRAP-Array opens up another dimension for storage arrays. It is orthogonal and complementary to RAID in the sense that RAID protects data in the dimension along an array of physical disks while TRAP protects data in the dimension along the time sequence.
En-route descent trajectory synthesis for air traffic control automation (2005)

This paper discusses en-route trajectory synthesis that is key to the Center-TRACON Automation System developed at NASA Ames for air traffic control automation. Based on trajectories produced in the Trajectory Synthesizer (TS) module, computer advisories are generated that help controllers to produce a safe, efficient, and expeditious flow of traffic for the extended terminal area. TS synthesizes trajectories from the initial position to the final position in the en-route area for one aircraft at a time by integrating a set of simplified point-mass equations. Specifically, TS separates the horizontal path from the vertical trajectory. The horizontal path is constructed from specified waypoints using straight lines and constant-radius turns. The vertical trajectory is divided into a series of flight segments. Three types of flight profiles are defined by connecting selected segments in a pre-determined order: fast, nominal and slow. Each profile can produce a certain range of arrival times. In numerical computations, a second-order Runge-Kutta scheme is used for integrating equations of motion. A regula falsi iterative scheme is employed to determine the speed that will meet a specified arrival time. Two flight scenarios are used to illustrate the TS solution procedure.
Wakes in Stratified Fluids (1979)

In this article we review research activities concerning wakes generated by moving bodies in stratified fluids. A wake is defined to be the non­ propagating disturbance produced by a moving body, and thus research activities concerning internal waves generated by a moving body are not included. Wakes have been of interest to many fluid dynamicists and engineers because they are a basic flow phenomenon associated with fluid flowing over an obstacle or with the movement of a natural or man-made body. The wake flow depends strongly on the Reynolds number RD == VoDjv, which is defined as the ratio of the inertia force to the viscous force. Here U 0 is the body speed, D is the characteristic length, e.g. the diameter of a cylinder or a sphere, and v is the kinematic viscosity of the fluid. For small Reynolds numbers, the viscous force dominates the inertia force and the wake is laminar. As the Reynolds number increases, the wake becomes unstable and a regular flow pattern, such as Karman's vortex street in the wake of a cylinder, can be observed. At still higher Reynolds numbers, the flow pattern becomes irregular and a turbulent flow is formed. Books written by Townsend (1956), Hinze (1959), and Schlichting ( 1960) can be referred to for further information about wakes. When the fluid is stratified thermally or with foreign additives, such as salt, a gravitational force, in addition to inertia and viscous forces, is exerted on the flow. A stratified fluid occurs very commonly in the
All-fiber phase-modulated master oscillator power amplifier for coherent communication (2000)

An all-fiber phase-modulated master oscillator power amplifier for free-space coherent communication is presented. A distributed-feedback fiber laser at 1.06 μm is used as master oscillator. A novel phase modulator based on a ZnO-coated single-mode fiber modulates the single frequency communication signal. The modulated signal is then amplified in a double-clad doped fiber power amplifier. Up to 1 W cw single-frequency output power, phase modulated at 196 MHz, has been obtained.

CAD Techniques for Embedded System Design (1999)

The structure and expression pattern of a human gene located within a homozygously deleted region of a metastatic prostate cancer have been characterized. Multiple cDNA fragments of this gene were isolated by hybrid capture with yeast artificial chromosome clones covering the deletion region. Eleven coding exons spanned 205-220 kb of the 730- to 970-kb deletion. The predicted amino acid sequence was 43% identical to that of an anonymous Caenorhabditis elegans gene and 20% identical to an accessory or regulatory subunit of the oligosaccharyltransferase enzyme complex in Saccharomyces cerevisiae. Hydrophobicity profiles of all three gene products were similar and showed four putative membrane-spanning domains in the molecules' C-terminal halves, suggesting a general conservation of function. The gene was expressed as an approximately 1.5-kb mRNA in most nonlymphoid human cells/tissues including prostate, lung, liver, and colon. Expression was detected in many epithelial tumor cell lines, but was undetectable by Northern blot or RT-PCR in 14 of 15 colorectal, 1 of 8 lung, and 1 of 4 liver cancer cell lines. Lack of expression in tumor cell lines was highly correlated with hypermethylation of a CpG island located at the gene's 5' end. These findings form a basis for further work on this candidate tumor suppressor gene.
Purification and characterization of the constitutive form of laccase from the basidiomycete <i>Coriolus hirsutus</i> and effect of inducers on laccase synthesis (1998)

An isolate of Coriolus hirsutus constitutively expresses substantial amounts of extracellular laccase on a defined growth medium. The most efficient inducer of extracellular laccase synthesis was syringaldazine, which increased the enzyme yield by 1000% at a concentration of 0·11 μM. The constitutive form of the enzyme was purified 312‐fold. Laccase from C. hirsutus , with an estimated molecular mass of 55 kDa and pI of 4·0, is a monomeric glycoprotein containing 12% carbohydrate consisting of mannose and N ‐acetylglucosamine. The laccase was found to contain 3·9–4·1 copper atoms per molecule. The absorption spectrum shows a maximum at 610 nm and a shoulder at 330 nm, which is typical of laccase possessing type 1 and type 3 copper atoms. The parameters of the first type of copper were determined by EPR as g ⊥ =2·046 and g ∥ =2·200, A ∥ =8·103×10 −3 cm −1 . Laccase was found to be a pH‐stable and thermostable enzyme. With organic substrates it exhibits a pH optimum of 4·5, but with the inorganic substrate K 4 [Fe(CN) 6 ] this decreased to 3·5. The highest efficiency of catalysis was observed with sinapinic acid as the substrate. The kinetic constants k cat and K m of this reaction were 578 s −1 and 24 μM respectively. It was established that the kinetics of the assayed reaction shows a Ping Pong mechanism.
