A Generalized "Polarity-Type" Costas Loop for Tracking MPSK Signals (1982)

A generalized tracking loop is proposed for tracking MPSK signals at high SNR. It is similar in form to the polarity-type Costas loop used for tracking QPSK signals, in which limiters in the arms provide the data estimates needed for data wipeoff in forming the loop error signal. For the MPSK signal, the hard limiters are replaced by "multivalued limiters" with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M/4 (M \geq 4)</tex> positive and negative values. The outputs of the multivalued limiters in each arm are the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</tex> projections of the data. The <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">S</tex> curve is computed for this MPSK loop, and plotted for different SNR's. A comparison is made to the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">S</tex> curve for the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</tex> th power loop (or <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</tex> -phase Costas loop), which is optimum for low SNR. From this comparison, a rough value of the "boundary" SNR can be obtained; this value may be used by the designer to determine which loop structure should be used. The advantage of the high SNR structure proposed here is that it is much simpler to implement than the corresponding low SNR structures.
A Dominant Phenocopy of Hypopituitarism in Transgenic Mice Resulting from Central Nervous System Synthesis of Human Growth Hormone (1989)

We have produced a line of transgenic mice in which expression of human GH has been detected only in the cerebral cortex. Both male and female transgenic mice are growth inhibited with respect to their nontransgenic littermates. Mouse GH mRNA and insulin-like growth factor-I mRNA levels in the pituitary and liver, respectively, are reduced, and circulating insulin-like growth factor-I levels are lower in these mice. Within the hypothalamus somatostatin mRNA levels are increased and GH-releasing factor mRNA levels are reduced compared to those in nontransgenic littermates. We suggest that the growth retardation in these mice is a consequence of the ectopic human GH disturbing the normal controls that regulate mouse GH synthesis and release from the pituitary. These mice provide a resource for analysis of the regulation of GH production and demonstrate that a dominant phenocopy can be made by producing transgenic mice that have local production of an extra-cellular hormone.

A Facile Synthesis of New 5<i>H</i>-Indazolo[3,2-<i>b</i>]benzo[<i>d</i>]-1,3-oxazines via One-Pot Intramolecular Bis-heterocyclizations (2007)

The parent 5H-indazolo[3,2-b]benzo[d]-1,3-oxazine heterocycle as well as a series of novel analogues have been synthesized utilizing two subsequent intramolecular heterocyclizations in one pot. A variety of diversity groups were added to explore the scope of this reaction and to provide a number of new compounds for biological screening.
Eukaryotic initiation factor 4A is the component that interacts with ATP in protein chain initiation. (1983)

Protein synthesis in a resolved homogenate of wheat germ requires ATP and eight factors functioning at the level of protein chain initiation. To identify the component(s) interacting with ATP, the different factors were treated with the ATP affinity analogue 5'-p-fluorosulfonylbenzoyladenosine (FSBA) and tested for their function in protein synthesis. The activity of eukaryotic initiation factor 4A (eIF4A) was strongly curtailed, whereas all other factors were unaffected. At a concentration of 250 microM, AMP, ADP, and ATP protected eIF4A against FSBA inactivation, whereas at a concentration 50 microM, protection was afforded only by ATP. GTP did not protect at a concentration of 250 microM. In another approach, the substrate analogue 2',3'-O-(2,4,6-trinitrophenyl)adenosine 5'-triphosphate (TNP-ATP) was found to inhibit protein synthesis in a manner, at least in part, competitive with ATP. Supplementing a TNP-ATP inhibited reaction with eIF4A substantially reversed the inhibition. Except for a small effect by factor C1, no reversal was obtained with any other component. Finally, a preincubation of ribosomes with ATP, mRNA, and eIF4A resulted in the formation of a complex capable of TNP-ATP-resistant amino acid incorporation. These data are interpreted to indicate that the primary interaction of ATP is with eIF4A. A model is proposed reconciling this conclusion with other observations relevant to the mRNA . ribosome attachment reaction.

Asthma in the Elderly Patient (1996)

Asthma is common in old age and carries significant morbidity and mortality. Most deaths due to asthma occur in old people. Often the diagnosis of asthma is overshadowed by other medical problems such as heart failure and emphysema, and thus elderly people may not receive optimal treatment. The treatment of an elderly patient with asthma is further complicated by concomitant disease and pharmacological interactions.
Computer‐based Cell Formation Incorporating ProcessSequence (1992)

Describes a philosophy of cell formation for cellular manufacturing which reasons that an analysis of the sequential processing of components is a fundamental requirement in understanding the problem, as well as being a necessity in generating the subsequent solution. Includes a résumé of the problems encountered in processing the pertinent industrial data coupled with an outline of the computer‐based methodology used to implement the philosophy.
Phase-shifted fiber Bragg gratings and their application for wavelength demultiplexing (1994)

It is shown that the transmission spectrum of a fiber Bragg grating can be tailored by incorporating single or multiple phase-shift regions during the fabrication process. Phase shifts open up narrowband transmission windows inside the stop band of the Bragg grating; transmitted wavelength can be changed by adjusting the amount of phase shift. As a specific application, we discuss how phase-shifted Bragg gratings can be used to make an all-fiber demultiplexer for multichannel lightwave systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of blood meal pH and irradiation on nursery pig performance1,2 (2003)

A total of 720 nursery pigs in three experiments were used to evaluate the effects of blood meal with different pH (a result of predrying storage time) and irradiation of spray-dried blood meal in nursery pig diets. In Exp. 1, 240 barrows and gilts (17 +/- 2 d of age at weaning) were used to determine the effects of blood meal pH (7.4 to 5.9) in diets fed from d 10 to 31 postweaning (7.0 to 16.3 kg of BW). Different lots of dried blood meal were sampled to provide a range in pH. Overall (d 0 to 21), pigs fed diets containing blood meal had greater ADG (P < 0.05) and ADFI (P < 0.05) than pigs fed diets without blood meal. Ammonia concentrations in blood meal rose as pH decreased. However, blood meal pH did not influence (P > 0.16) ADG, ADFI, or gain:feed (G:F). In Exp. 2, 180 barrows (17 +/- 2 d of age at weaning) were used to determine the effects of post drying pH (7.6 to 5.9) and irradiation (gamma ray, 9.5 kGy) of blood meal on growth performance of nursery pigs from d 5 to 19 postweaning (6.8 to 10.1 kg of BW). One lot of whole blood was isolated with 25% of the total lot dried on d 0, 3, 8, and 12 after collection to create a range in pH. Overall, pigs fed blood meal had improved G:F (P < 0.01) compared to pigs fed the control diet. Similar to Exp. 1, the ammonia concentration of blood meal increased with decreasing pH. Blood meal pH did not influence ADG, ADFI, or G:F (P > 0.21), but pigs fed irradiated blood meal (pH 5.9) had greater ADG and G:F (P < 0.05) than pigs fed nonirradiated blood meal (pH 5.9). In Exp. 3, 300 barrows (17 +/- 6 d of age at weaning) were used to determine the effects of blood meal irradiation source (gamma ray vs. electron beam) and dosage (2.5 to 20.0 kGy) on growth performance of nursery pigs from d 4 to 18 postweaning (8.7 to 13.2 kg of BW). Overall, the mean of all pigs fed blood meal did not differ in ADG, ADFI, or G:F (P > 0.26) compared to pigs fed the control diet without blood meal. Pigs fed irradiated blood meal had a tendency (P < 0.10) for increased G:F compared with pigs fed nonirradiated blood meal. No differences in growth performance were detected between pigs fed blood meal irradiated by either gamma ray or electron beam sources (P > 0.26) or dosage levels (P > 0.11). These studies suggest that pH alone as an indicator of blood meal quality is not effective and irradiation of blood meal improved growth performance in nursery pigs.
Immunohistochemistry and Polymerase Chain Reaction for the Detection of Lawsonia intracellularis in Porcine Intestinal Tissues with Proliferative Enteropathy. (2000)

Detection method of Lawsonia intracellularis was studied in formalin-fixed paraffin-embedded intestinal tissues from 5 naturally infected pigs by immunohistochemistry with a monoclonal antibody against outer membrane protein of L. intracellularis. Warthin-Starry silver stain revealed clusters of argyrophilic, slightly curved rod-shaped organisms in the apical cytoplasm of enterocytes. Immunohistochemical staining with a L. intracellularis-specific monoclonal antibody confirmed the presence of the organism in the apical cytoplasm of hyperplastic enterocytes. The presence of L. intracellularis in the ileum of pig with proliferative enteropathy was confirmed by polymerase chain reaction (PCR) further on the basis of amplification of 319 base pair products specific for porcine L. intracellularis chromosomal DNA. Immunohistochemistry and PCR may be a complementary method to confirm the diagnosis of L. intracellularis infection in pigs.
Modeling and variable selection in epidemiologic analysis. (1989)

This paper provides an overview of problems in multivariate modeling of epidemiologic data, and examines some proposed solutions. Special attention is given to the task of model selection, which involves selection of the model form, selection of the variables to enter the model, and selection of the form of these variables in the model. Several conclusions are drawn, among them: a) model and variable forms should be selected based on regression diagnostic procedures, in addition to goodness-of-fit tests; b) variable-selection algorithms in current packaged programs, such as conventional stepwise regression, can easily lead to invalid estimates and tests of effect; and c) variable selection is better approached by direct estimation of the degree of confounding produced by each variable than by significance-testing algorithms. As a general rule, before using a model to estimate effects, one should evaluate the assumptions implied by the model against both the data and prior information.
Clinicopathological Features of Adult T-Cell Leukemia with CD30 Antigen Expression (1994)

Recently, several cases of adult T-cell leukemia (ATL) with CD30 antigen have been reported, but its clinical significance remains unknown. Accordingly, we studied CD30 antigen expression in ATL cases and documented the clinicopathological characteristics of these cases. Immunohistochemical and clinical characteristics were studied in 46 patients with malignant lymphoma or benign lesions of lymphoid tissue, who had antibodies against human T-cell leukemia virus type I (HTLV-I). Monoclonal integration of HTLV-I provirus was demonstrated in the tumor cells in 36 (ATL) of the 46 cases. CD30 antigen expression was evident in seven of these 36 cases (19.4%), however it was not seen in any of the ten cases lacking the integration of HTLV-I provirus. A comparison of ATL cases with and without CD30 antigen expression revealed significantly larger numbers of abnormal lymphocytes in the peripheral blood and lower serum calcium levels in ATL expressing CD30 antigen.
Lipid composition of carcass tissue from transgenic pigs expressing a bovine growth hormone gene (1994)

Fatty acid profiles and cholesterol content of whole-carcass ground tissue were compared from 26 transgenic (T) pigs expressing a bovine growth hormone gene (bGH) to 26 sibling control (C) pigs. All pigs were fed a common diet and were slaughtered at five different live weights: 14, 28, 48, 68, and 92 kg. The left side of each intact carcass was ground and tissue samples were analyzed for lipid composition and cholesterol content. At 14-kg body weight, carcasses from bGH-T pigs contained 38% less fat, 44% less saturated fatty acids (SFA), 48% less monounsaturated fatty acids (MUFA), and 38% less polyunsaturated fatty acids (PUFA) than C pigs. At 28 kg, bGH-T pigs had 38% less total carcass fat, 42% less SFA, 46% less MUFA, and 24% less PUFA than C pigs. At 48-kg body weight, bGH-T pigs contained 48% less carcass fat, 55% less SFA, 59% less MUFA, and 22% less PUFA than C pigs. At 68 kg, bGH-T pigs had 78% less carcass fat, 78% less SFA, 79% less MUFA, and 53% less PUFA than C pigs. At 92 kg, carcasses from bGH-T pigs contained 85% less carcass fat, 85% less SFA, 91% less MUFA, and 66% less PUFA than those from C pigs. Cholesterol content was not different between bGH-T pigs and C pigs at any of the carcass weights. The trend was for cholesterol content to decrease from the 14- to 92-kg weight group. These results suggest a dilution effect of carcass fat and fatty acids in carcass tissue from bGH-T pigs with increasing live weight.

Regularisation of nonlinear inverse problems: imaging the near-surface weathering layer (1990)

The authors give a detailed comparison of damping and difference smoothing as a means of regularising inverse calculations. They show that damping is potentially disastrous in multiparameter inversions since the small singular values may control long-spatial-wavelength features in the solution, whereas difference smoothing avoids this problem entirely by down-weighting the rough singular vectors wherever they happen to lie in the spectrum. Further, they show that regularisation can produce rather different results depending on whether the inversion is done via jumping or creeping. In particular, they find that if the inversion is regularised by difference smoothing, then jumping and creeping will give the same results only if the initial model is smooth. They illustrate these ideas by inverting refracted seismic arrivals to image the Earth's near-surface weathering layer. This 'refraction statics' problem has a fundamental long-wavelength ambiguity, so damping merely introduces undesirable long-wavelength perturbations to the solution.
Improvements in current gain and breakdown voltage of silicon MIS heterojunction emitter transistors (1986)

Significant improvements in the current gain and in the breakdown voltage of high gain devices are reported for silicon-bipolar transistors. These improvements were obtained by the use of a heterojunction MIS tunneling emitter with the tunneling oxide properties more carefully optimized than in earlier devices. Common-emitter current gains above 3 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> are reported for devices with a breakdown voltage above 30 V.
Vitamin A Degradation and Light-Oxidized Flavor Defects in Milk (2002)

To determine the effects of light exposure on vitamin A degradation and on light-oxidized flavor development, samples of whole, reduced fat, and nonfat milk were exposed to fluorescent light (either 1000 or 2000 lx) at time intervals of 2, 4, 8, or 16 h. Measurable vitamin A losses occurred at 2, 4, and 16 h at 2000 lx for nonfat, reduced fat and whole milk, respectively. Moderate light-oxidized flavors were detected after 4 h of light exposure (2000 lx) in the whole and reduced fat milk and after 8 h in nonfat milk. The different types of milk show a significant difference in relative flavor scores. By 16 h at 2000 lx, relative light-oxidized flavor development was lower in nonfat milk than in whole or reduced fat milk. The presence of milk fat appears to protect against vitamin A degradation in fluid products, but adversely affects the flavor quality of milk after exposure to light. In summary, these findings demonstrate that even a brief, moderate light exposure (2 h; 2000 lx) can reduce the nutritional value and flavor quality of fluid milk products.
Coupling of concanavalin A to cellulose hollow fibers for use in glucose affinity sensor (1986)

This article describes a method for the chemical immobilization of concanavalin A (Con A) on the inside wall of a single hollow cellulose fiber for use in glucose affinity sensor. Periodate oxidation of cellulose fiber followed by a spacer for Con A attachment was deemed to be the most optimal procedure for achieving the highest sensitivity of the sensor without compromising its physical integrity. The effects of variables like the duration of periodate oxidation and its concentration and pH of the spacer coupling step and its duration have been examined. The mechanical strength of the hollow fiber as well as its permeability to the analyte (glucose) have been evaluated prior to and after Con A coupling process. It has been demonstrated that Con A bound hollow fiber prepared according to the procedure outlined here can be successfully used to construct glucose affinity sensor for operation in the physiological range of glucose concentrations.

A sensorless wide-speed range SRM drive with optimally designed critical rotor angles (2002)

A switched reluctance motor (SRM) drive optimized to achieve sensorless operation over wide-speed range with lowered torque-ripple is presented in this paper. Wide-speed range is obtained by phase advancing between two extreme critical rotor angles; lowered torque-ripple is obtained by effective torque sharing of adjacent phases; and sensorless operation is achieved through a sliding-mode observer (SMO) based algorithm. The research reveals the method of determination of critical rotor angles from machine geometry and material properties and suggests the design considerations to optimize the control parameters. The research also defines the phase advancing strategy between the critical rotor angles and the torque sharing mechanism by introducing a natural commutation period. The integrated SRM drive with simulation and experimental results using TMS320C30 DSP are presented for verification.

Fission-fragment mass and energy distributions and mass-versus-energy correlations have been obtained for $^{252}\mathrm{Cf}$ spontaneous fission and $^{235}\mathrm{U}$ thermal-neutron-induced fission. Silicon surface-barrier detectors were used in energy correlation measurements; absolute fragment energies were obtained by means of the mass-dependent energy calibration developed recently at this laboratory. Average total fragment kinetic energies before neutron emission are found to be 186.5\ifmmode\pm\else\textpm\fi{}1.2 MeV for $^{252}\mathrm{Cf}$ and 171.9\ifmmode\pm\else\textpm\fi{}1.4 MeV for $^{235}\mathrm{U}$. Detailed experimental results are given and compared with those of other experiments. Observed fine structure in the fragment mass distribution and in the average total fragment kinetic energy as a function of mass is correlated with the energetically preferred even-even nucleon configurations in the fragments. New determinations of the root-mean-square width of the total-kinetic-energy distribution as a function of mass show structure which is also correlated with the energetically preferred even-even fragment configurations. Fission-neutron and gamma-ray data of other experiments are used with the new fragment kinetic energies presented here to examine the total energy balance for fission for the two cases studied.

Journal Lagtime (1994)

When selecting journals to place their work, authors are often concerned with lagtime, as well as other perceptions of quality and reputation. Lagtime refers to the average period between submission and publication of accepted papers and is a common figure of merit to evaluate journal responsiveness and the rapidity of appearance in print.
