Engineering Noise Control (2003)

This classic and authoritative student textbook contains information that is not over simplified and can be used to solve the real world problems encountered by noise and vibration consultants as well as the more straightforward ones handled by engineers and occupational hygienists in industry. The book covers the fundamentals of acoustics, theoretical concepts and practical application of current noise control technology. It aims to be as comprehensive as possible while still covering important concepts in sufficient detail to engender a deep understanding of the foundations upon which noise control technology is built. 
Topics which are extensively developed or overhauled from the fourth edition include sound propagation outdoors, amplitude modulation, hearing protection, frequency analysis, muffling devices (including 4-pole analysis and self noise), sound transmission through partitions, finite element analysis, statistical energy analysis and transportation noise. For those who are already well versed in the art and science of noise control, the book will provide an extremely useful reference. A wide range of example problems that are linked to noise control practice are available on www.causalsystems.com for free download.
Generation of 30 fs pulses tunable from 189 to 240 nm with an all-solid-state setup (2012)

Fully tunable deep UV pulses of 30 fs duration are generated in an all-solid-state scheme from 200 fs long pump pulses of a Ti:sapphire amplifier. The tunability comes from a noncollinear optical parametric amplifier with tailored spectral width. The output pulses are frequency-doubled in a 50 μm BBO crystal and subsequently mixed in a 32 μm BBO crystal with part of the Ti:sapphire output. The compression is solely performed in the visible. This makes the setup extremely simple and efficient. Less than 400 μJ pump energy suffice to obtain submicrojoule deep UV pulses. The strategy for the bandwidth and chirp management is explained in detail.
X-Ray and Neutron Diffraction Study of Antiferroelectric Lead Zirconate, PbZr<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">O</mml:mi></mml:mrow><mml:mrow><mml:mn>3</mml:mn></mml:mrow></mml:msub></mml:mrow></mml:math> (1957)

The room-temperature structure of antiferroelectric lead zirconate, PbZr${\mathrm{O}}_{3}$, has been studied by x-ray and neutron diffraction. The symmetry is orthorhombic (pseudotetragonal) with lattice parameters $a=5.88$ A, $b=11.77$ A, $c=8.22$ A. The space group is $\mathrm{Pba}2$ and there are 8 formula units in the unit cell. The structure results from slight distortions of the cubic perovskite lattice, which the crystal assumes above 230\ifmmode^\circ\else\textdegree\fi{}C.With respect to the ideal perovskite structure, Pb atoms suffer antiparallel shifts along the former cubic [110] direction; oxygen atoms also suffer antiparallel shifts within the (001) plane and, in addition, unbalanced antiparallel shifts along the $c$ direction.The noncentric symmetry is in accord with the presence of a small piezoelectric effect as reported by Roberts. The oxygen octahedra surrounding the Zr atoms appear to be distorted, and it is possible to explain the strong optical anisotropy within the (001) plane as well as the pseudotetragonality ($b=2a$).
Current-Sharing/Voltage-Distribution Control for Interconnected DC-DC Converters (2007)

This paper presents advanced interconnection and control approaches for three currentmode, shared-bus converter architectures: (1) parallel-input parallel-output (PIPO), (2) parallelinput series-output (PISO), and (3) series-input parallel-output (SIPO). Without proper control, nonuniform current sharing or voltage distribution may exist among interconnected DC-DC converters, negatively impacting reliability. Using the control schemes presented herein, reliable and robust power system performance is achievable from the series and/or parallel interconnection of commercial-off-the-shelf (COTS) DC-DC converters. In particular, PIPO connected COTS converters have been well-known and already achieved uniform current-sharing by using the provided parallel control port as a common “shared bus” for commanding the parallel-connected converters to operate as voltage-controlled current sources. This paper presents two control alternatives for PIPO converter systems based on the “shared-bus” approach: (1) minimum-voltageerror shared-bus and (2) maximum-voltage-error shared-bus. Furthermore, the current-mode shared-bus converters extend their applications to power system architectures configured as PISO and SIPO. Employing a PISO (or SIPO) interconnect method, current-mode COTS converters can transform their system input voltages to higher (or lower) system output voltages, provide flexibility for power system expansion, and preserve system efficiencies equal to that obtained from stand-alone converters. The system achieves robust stability and uniform voltage sharing among series-connected converters through unique output and input voltage distribution control approaches for the PISO and SIPO power architectures. Two effective approaches to uniform voltage distribution control, the central-limit (CL) and maximum-limit (ML) distribution, will be discussed. Both computer simulation and experimental prototypes validate both series-connected power converter architectures with the two control approaches.
Service-oriented Software Development (2005)

The service-oriented development includes two aspects: service design and service integration. Based on the restraint from the correlation among the methods of cooperative components to form Web services, the paper proposes the model of service component, analyses the correlation and discusses the rule to form service. Furthermore, it puts forward the concept and method of in infrastructure to reduce the dependency relationship during invoking Web services.
Effects of several species of human leukocyte interferon on cytotoxic activity of NK cells and monocytes (1983)

Ten species of purified human leukocyte interferon were tested for their ability to modulate the cytolytic activity of natural killer (NK) cells and the cytolytic and cytostatic activities of monocytes. The interferon species were tested at several antiviral titers and examined for quantitative differences in their ability to modulate immunological function. At the higher doses of interferon (i.e., greater than 500 units) all of the interferon species demonstrated significant augmentation of cytolysis and cytostasis. However, when low levels (i.e., 10-50 units) of interferon were employed, appreciable differences between the various interferon species were seen. A similar pattern of relative potency among the various species of pure leukocyte interferon was seen for augmentation of cytolysis by monocytes and NK cells. In contrast, a different pattern of relative potency was observed for augmentation of cytostasis. These results demonstrated substantial quantitative differences (as much as 100-fold) in the ability of the various species of human leukocyte interferon to induce significant levels of augmentation of these cell-mediated functions. Such results should have significant impact in choosing a specific interferon species for appropriate clinical trials.

Inhibition of tumorigenic potential and prostate‐specific antigen expression in LNCaP human prostate cancer cell line by 13‐<i>cis</i>‐retinoic acid (1994)

Prostate-specific antigen (PSA) is a member of the kallikrein family and has been an important biological marker for prostate cancer. The mechanisms regulating PSA expression in prostatic cancer cells are unclear. The present study was designed to elucidate the role of 13-cis-retinoic acid (RA) in regulation of PSA and the tumorigenic potential of the human prostate cancer cell line LNCaP. The growth regulation of LNCaP cells was examined by DNA synthesis and doubling time. The tumorigenic potential of prostate cancer cells was analyzed by soft agar colony-forming assay, in vitro invasion assay, type IV collagenase assay and binding to extracellular matrix assay. The nuclear receptors for retinoic acid (RAR alpha, -beta, -gamma and RXR alpha, -beta, -gamma) as well as PSA mRNA were determined by Northern blot using specific oligonucleotide probes. Our results suggest that 13-cis-RA significantly inhibits PSA secretion and expression both at the mRNA and protein levels compared with untreated cells. Electron microscopic studies suggest that after 13-cis-RA treatment, cells become more differentiated as they contain lumina, lined by plasma membrane and microvilli. Prostate cancer cell growth and tumorigenic potential after 13-cis-RA treatment was significantly decreased compared with controls. Nude mice tumorigenicity studies showed that 13-cis-RA-treated cells produced significantly smaller tumors compared with untreated cell tumors. There was also a significant increase in the expression of RXRa mRNA after 13-cis-RA treatment compared with untreated cells.
Information Management System: Master Links-A Hierarchical Data System (1973)

MASTER LINKS is a software system used to build, administer, and access hierarchical data bases. It is designed to operate in a time-sharing environment, and, in particular, it allows multiple concurrent updates and retrievals on the same data base. A BUILD module is used to specify the hierarchical configuration of a data base and an initial “storage mapping” of the elements of the hierarchy into a particular file layout. A set of administrative routines is provided for altering the mapping and other such maintenance purposes. The access routines have three levels of interface, from primitive and flexible to sophisticated and functional. The interfaces are all defined in terms of the hierarchical structure and independent of the storage mapping. Thus, an alteration of the storage mapping for a data base does not require changing any programs that access data using these interfaces. The lowest-level interface enables the calling program to add to the data base, update a value, or retrieve a value, in terms of a hierarchy position. The second-level interface facilitates traversal of a hierarchy by enabling the calling program to specify portions of the hierarchy over which a process is to operate. Such a specification, called an “access tree,” consists of data which can be generated at execution time by the calling routine. As in the first level, data are transferred one at a time. The third-level interface is a function evaluation mechanism which computes values from data base values and other computed values according to function definitions passed to it at execution time. Like an access tree, a function definition is itself data which can be constructed at execution time by the client process.

Fouling of a Sweet Crude Oil under Inert and Oxygenated Conditions (1999)

Fouling of a sweet crude oil derived from oil sands was studied in a re-circulation heating loop to identify causes of refinery preheater fouling. Oil was re-circulated for periods of up to 6 days through an electrically heated annular probe. The oil was maintained under gaseous atmospheres with air/nitrogen molar ratios from zero to 0.18, at total pressures of 460 kPa. The effects of wall and bulk temperature, flow velocity, dissolved oxygen content, and mineral particle additions on the fouling rate are reported.
Cold welding: a phenomenon for spontaneous self-healing and shape genesis at the nanoscale (2015)

Making direct and intimate connections between nanoscale objects under ambient conditions (<italic>cold welding</italic>) is a powerful approach for the bottom-up fabrication of hierarchical, multifunctional nanomaterials endowed with features superior to those arising from an individual entity.
μ-Opioid Receptor Mediates Chronic Restraint Stress-Induced Lymphocyte Apoptosis (2002)

Psychological stress is associated with immunosuppression in both humans and animals. Although it was well established that psychological stressors stimulate the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, resulting in the release of various hormones and neurotransmitters, the mechanisms underlying these phenomena are poorly understood. In this study, mu-opioid receptor knockout (MORKO) mice were used to investigate whether the mu-opioid receptor mediates the immunosuppression induced by restraint stress. Our results showed that wild-type (WT) mice subjected to chronic 12-h daily restraint stress for 2 days exhibited a significant decrease in splenocyte number with a substantial increase in apoptosis and CD95 (Fas/APO-1) expression of splenocytes. The effects are essentially abolished in MORKO mice. Furthermore, inhibition of splenic lymphocyte proliferation, IL-2, and IFN-gamma production induced by restraint stress in WT mice was also significantly abolished in MORKO mice. Interestingly, both stressed WT and MORKO mice showed a significant elevation in plasma corticosterone and pituitary proopiomelanocortin mRNA expression, although the increase was significantly lower in MORKO mice. Adrenalectomy did not reverse restraint stress-induced immunosuppression in WT mice. These data clearly established that the mu-opioid receptor is involved in restraint stress-induced immune alterations via a mechanism of apoptotic cell death, and that the effect is not mediated exclusively through the glucocorticoid pathway.
Forkhead Box C1 Regulates Human Primary Keratinocyte Terminal Differentiation (2016)

The epidermis serves as a critical protective barrier between the internal and external environment of the human body. Its remarkable barrier function is established through the keratinocyte (KC) terminal differentiation program. The transcription factors specifically regulating terminal differentiation remain largely unknown. Using a RNA-sequencing (RNA-seq) profiling approach, we found that forkhead box c 1 (FOXC1) was significantly up-regulated in human normal primary KC during the course of differentiation. This observation was validated in human normal primary KC from several different donors and human skin biopsies. Silencing FOXC1 in human normal primary KC undergoing differentiation led to significant down-regulation of late terminal differentiation genes markers including epidermal differentiation complex genes, keratinization genes, sphingolipid/ceramide metabolic process genes and epidermal specific cell-cell adhesion genes. We further demonstrated that FOXC1 works down-stream of ZNF750 and KLF4, and upstream of GRHL3. Thus, this study defines FOXC1 as a regulator specific for KC terminal differentiation and establishes its potential position in the genetic regulatory network.
Modification of Escherichia coli B glutathione synthetase with polyethylene glycol for clinical application to enzyme replacement therapy for glutathione deficiency (1996)

Glutathione synthetase of Escherichia coli B was modified with polyethylene glycol, and the properties of the resultant modified enzyme were investigated. The thermal stability of the modified enzyme and its resistance against several proteases increased compared with those of the native enzyme. The modified enzyme was injected intravenously via the rat tail vein, and the circulating life of the enzyme in plasma was monitored. The half-life of the native enzyme was 50 min, whereas that of the modified enzyme was approximately 24 h. The systemic anaphylaxis reaction was tested by using rats intravenously injected with the native and modified enzymes. For the native enzyme, strong reactions such as dyspnea and tumble were observed; however, no symptom or only a very weak reaction, such as scratching, was observed with the modified enzyme.

ABSTRACT Coupling of the sodium salt of S-(methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-D-glycero-α-galacto-2-nonulopyranosylonate)-(2→'6)-2,3,4-tri-O-acetyl-1,6-dithio-β-D-glucopyranose (5), -β-D-galactopyranose (8), or S-(methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-D-glycero-α-D-galacto-2-nonulopyranosylonate)-(2→'6)-O-(2,3,4-tri-O-acetyl-6-thio-β-D-galactopyranosyl)-(1→'4)-2,3,6-tri-O-acetyl-1-thio-β-D-glucopyranose (12), which were prepared from the corresponding 1-hydroxy compounds, 1, 2, and 9, via 1-chlorination, displacement with thioacetyl group, and S-deacetylation, with (2S,3R,4E)-2-azido-3-O-benzoyl-1-O-(p-toluenesulfonyl)-4-octadecene-1,3-diol (13), gave the corresponding β-thioglycosides 14, 18 and 22, respectively in good yields. The β-thioglycosides obtained were converted, via selective reduction of the azide group, condensation with octadecanoic acid, and removal of the protecting groups, into the title compounds.

Molecular cloning and expression of cDNAs encoding two isoforms of protein phosphatase 2C beta from mouse testis. (1994)

Two isoforms of protein serine/threonine phosphatase were isolated and sequenced from mouse testis. A deletion of 48 nucleotides of PP2C beta 4 cDNA in comparison with PP2C beta 3 cDNA resulted in different COOH-terminal sequences of 12 and 15 amino acids, respectively. These COOH-terminal sequences of PP2C beta 3 and PP2C beta 4 were further found to be different from those of isoforms MPP beta 1 and MPP beta 2 of mouse PP2C beta reported (Terasawa, et al. Arch. Biochem. Biophys. 307: 342-349, 1993). The common sequence of 378 amino acids from these four isoforms of mouse PP2C beta exhibited 95% identity with the corresponding sequence of rat PP2C beta. The mRNAs of approximately 2.0 Kb for PP2C beta 3 and PP2C beta 4 were expressed only in testis, while the mRNAs of 3.3 Kb and 8.5 Kb for MPP beta 1 and MPP beta 2, respectively, were found in somatic tissues.

Coarse and fine grain objects in a distributed persistent store (2002)

This paper describes our experiences with the development of a Distributed Shared Memory (DSM) based on a single, very large, paged virtual memory space distributed across an arbitrary number of discrete nodes connected to a network of homogeneous computers. The DSM supports two object granularities: coarse-grain objects called modules and fine-grain objects called segments. We show that support for both modules and segments has advantages in the areas of naming and location, protection, data consistency, transaction management and garbage collection.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Static and fatigue properties of two new low‐viscosity PMMA bone cements improved by vacuum mixing (1996)

With the objectives of reducing toxicity and improving the mechanical properties of the prior Sulfix®-6 cement, a new low-viscosity bone cement with a new catalyst (Sulfix®-60), and a gentamycin containing cement (Allofix-G®) were developed. Although static strength could be improved in comparison with the older Sulfix®-6 cement, investigations regarding improved fatigue strength and the influence of vacuum mixing on the mechanical properties were missing. Dynamic weakness was the major disadvantage of the older Sulfix®-6 cement. To investigate fatigue strength specimens of the new bone cements were tested with load guiding until breakage or 20 million cycles. In the three series, hand mixing, vacuum mixing, and vacuum mixing with additional pressurization were performed, respectively. Vacuum mixing led to increased fatigue stability from 6.3 to 9.1 MPa for Sulfix®-60, and from 6.3 to 8.2 MPa for Allofix-G®. Additional compression had no significant effect. A 200% increased fatigue strength was detectable in comparison with the older cement. In the four-point bending test, similar results were found. It could be proved that an increased polymerization rate achieved with the use of the new catalyst was responsible for the improved mechanical properties of the new bone cement Sulfix®-60. © 1996 John Wiley & Sons, Inc.
