Faculty Publications

The authors examined the impact of smoking status on the relation between body mass index (weight (kg)/height (m)2) and mortality across a group of 15 diverse observational studies. The studies included a heterogeneous sample of national samples, cohort studies with mortality follow-up, and clinical trials. Consideration of the data according to natural strata resulted in the formation of 42 analytic cohorts. The authors examined survival through the end of follow-up for each study, as influenced by body mass index, age, and current smoking status at baseline, using a proportional hazards model to describe the relation between body mass index and …

Creation Of An Ultracold Neutral Plasma, Scott D. Bergeson, T. C. Killian, S. Kulin, L. A. Orozco, C. Orzel, S. L. Rolston Dec 1999

Creation Of An Ultracold Neutral Plasma, Scott D. Bergeson, T. C. Killian, S. Kulin, L. A. Orozco, C. Orzel, S. L. Rolston

Faculty Publications

We report the creation of an ultracold neutral plasma by photoionization of laser-cooled xenon atoms. The charge carrier density is as high as 2×10^9 cm^-3, and the temperatures of electrons and ions are as low as 100 mK and 10 uK, respectively. Plasma behavior is evident in the trapping of electrons by the positive ion cloud when the Debye screening length becomes smaller than the size of the sample. We produce plasmas with parameters such that both electrons and ions are strongly coupled.

Influence Of The Medium Length On High-Order Harmonic Generation, C. Delfin, C. Altucci, F. De Filippo, C. De Lisio, M. B. Gaarde, A. L'Huillier, L. Roos, C. G. Wahlström Nov 1999

Influence Of The Medium Length On High-Order Harmonic Generation, C. Delfin, C. Altucci, F. De Filippo, C. De Lisio, M. B. Gaarde, A. L'Huillier, L. Roos, C. G. Wahlström

Faculty Publications

We study high-order harmonic generation using a 110 fs Ti:sapphire laser loosely focused into a variable-length gas cell filled with neon or argon at 5 mbar pressure. The harmonic intensity is recorded as a function of the medium length, varying between 2 and 21 mm. Several cases are examined, the 17th and the 29th harmonic in argon, and the 29th and 51st harmonic in neon, at the same intensity 4 × 1014 W cm-2. We find that the length which maximizes the harmonic yield varies from 10 mm to more than 20 mm. We discuss the different effects affecting the …

Selective Excitation And Thermal Quenching Of The Yellow Luminescence Of Gan, John S. Colton, P. Y. Yu, K. L. Teo, E. R. Weber, P. Perlin, I. Grzegory, K. Uchida Nov 1999

Selective Excitation And Thermal Quenching Of The Yellow Luminescence Of Gan, John S. Colton, P. Y. Yu, K. L. Teo, E. R. Weber, P. Perlin, I. Grzegory, K. Uchida

Faculty Publications

We report the observation of narrower structures in the yellow luminescence of bulk and thin-film n-type GaN, using the technique of selective excitation. These fine structures exhibit thermal quenching associated with an activated behavior. We attribute these fine structures to phonons and electronic excitations of a shallow donor-deep acceptor complex, and determine its activation energy for delocalization. Our results suggest that in addition to distant donor-acceptor pairs, the yellow luminescence can also involve emission complexes of shallow donors and deep acceptors.

Regulation Of The Dolichol Pathway In Human Fibroblasts By The Endoplasmic Reticulum Unfolded Protein Response, William T. Doerrler, Mark A. Lehrman Nov 1999

Regulation Of The Dolichol Pathway In Human Fibroblasts By The Endoplasmic Reticulum Unfolded Protein Response, William T. Doerrler, Mark A. Lehrman

Faculty Publications

Accumulation of unfolded proteins within the endoplasmic reticulum (ER) of eukaryotic cells triggers the unfolded protein response (UPR), which activates transcription of several genes encoding ER chaperones and folding enzymes. This study reports that conversion of dolichol-linked Man2-5GIcNAc2 intermediates into mature Glc3Man9GlcNAc2 oligosaccharides in primary human adult dermal fibroblasts is also stimulated by the UPR. This stimulation was not evident in several immortal cell lines and did not require a cytoplasmic stress response. Inhibition of dolichol-linked Glc3Man9GlcNAc2 synthesis by glucose deprivation could be counteracted by the UPR, improving the transfer of Glc3Man9GlcNAc2 to asparagine residues on nascent polypeptides. Glycosidic processing …

Tracking Of Physical Activity, Physical Inactivity, And Health-Related Physical Fitness In Rural Youth, Russell R. Pate, Stewart G. Trost, Marsha Dowda, Alise E. Ott, Dianne S. Ward, Ruth P. Saunders, Gwen A. Felton Nov 1999

Tracking Of Physical Activity, Physical Inactivity, And Health-Related Physical Fitness In Rural Youth, Russell R. Pate, Stewart G. Trost, Marsha Dowda, Alise E. Ott, Dianne S. Ward, Ruth P. Saunders, Gwen A. Felton

Faculty Publications

This study examined the tracking of selected measures of physical activity, inactivity, and fitness in a cohort of rural youth. Students (N=181, 54.7% female, 63.5% African American) completed test batteries during their fifth- (age=10.7±0.7 years), sixth-, and seventh-grade years. The Previous Day Physical Activity Recall (PDPAR) was used to assess 30-min blocks of vigorous physical activity (VPA), moderate-to-vigorous physical activity (MVPA), TV watching and other sedentary activities, and estimated energy expenditure (EE). Fitness measures included the PWC 170 cycle ergometer test, strength tests, triceps skinfold thickness, and BMI. Intraclass correlation coefficients (ICCs) for VPA, MVPA, and after-school EE …

Accuracy Of Scatterometer-Derived Winds Using The Cramer-Rao Bound, David G. Long, Travis E. Oliphant Nov 1999

Accuracy Of Scatterometer-Derived Winds Using The Cramer-Rao Bound, David G. Long, Travis E. Oliphant

Faculty Publications

A wind scatterometer makes measurements of the normalized radar-backscatter coefficient O of the ocean surface. To retrieve the wind, a geophysical model function (GMF), which relates O to the near-surface wind, is used. The wind vector can be estimated using maximum-likelihood techniques from several O measurements made at different azimuth angles. The probability density of the measured O is assumed to be Gaussian with a variance that depends on the true O and therefore, depends on the wind through the GMF. With this model for wind estimation, the Cramer-Rao (C-R) bound is derived for wind estimation, and its implications for …

Piezoelectric Doping In Alingan/Gan Heterostructures, M. Asif Khan, J. W. Yang, Grigory Simin, R. Gaska, M. S. Shur, A. D. Bykovski Nov 1999

Piezoelectric Doping In Alingan/Gan Heterostructures, M. Asif Khan, J. W. Yang, Grigory Simin, R. Gaska, M. S. Shur, A. D. Bykovski

Faculty Publications

We report on the piezoelectricdoping and two-dimensional (2D) electron mobility in AlInGaN/GaN heterostructures grown on 6H–SiC substrates. The contribution of piezoelectricdoping to the sheet electron density was determined using an In-controlled built-in strain-modulation technique. Our results demonstrate that in strained AlGaN/GaN heterostructures, the piezoelectric field generates at least 50% of the 2D electrons. The strain modulation changes the potential distribution at the heterointerface, which, in turn, strongly affects the 2D electron mobility, especially at cryogenic temperatures. The obtained results demonstrate the potential of strain engineering and piezoelectricdoping for GaN-based electronics.

Low-Frequency Noise In N-Gan With High Electron Mobility, M. E. Levinshtein, S. L. Rumyantsev, D. C. Look, R. J. Molnar, M. Asif Khan, Grigory Simin, V. Adivarahan, M. S. Shur Nov 1999

Low-Frequency Noise In N-Gan With High Electron Mobility, M. E. Levinshtein, S. L. Rumyantsev, D. C. Look, R. J. Molnar, M. Asif Khan, Grigory Simin, V. Adivarahan, M. S. Shur

Faculty Publications

We report on the results of measurements of low frequency noise in n-type gallium nitride (GaN) grown on sapphire with 300 K electron mobility of 790 cm2/V s. The noise spectra have the form of 1/f noise with a Hooge parameter α of approximately 5×10−2. This value of α is two orders of magnitude smaller than that observed before in n-GaN. The obtained results show that the level of flicker noise in GaN, just like that in GaAs and Si, strongly depends on the structural perfection of the material (the amplitude of the 1/f …

Validity Of The Previous Day Physical Activity Recall (Pdpar) In Fifth-Grade Children, Stewart G. Trost, Dianne S. Ward, Ben Mcgraw, Russell R. Pate Nov 1999

Validity Of The Previous Day Physical Activity Recall (Pdpar) In Fifth-Grade Children, Stewart G. Trost, Dianne S. Ward, Ben Mcgraw, Russell R. Pate

Faculty Publications

This study evaluated the validity of the Previous Day Physical Activity Recall (PDPAR) self-report instrument in quantifying after-school physical activity behavior in fifth-grade children. Thirty-eight fifth-grade students (mean age, 10.8 ± 0.1; 52.6%; female; 26.3% African American) from two urban elementary schools completed the PDPAR after wearing a CSA WAM 7164 accelerometer for a day. The mean within-subject correlation between self-reported MET level and total counts for each 30-min block was 0.57 (95% C.I., 0.51-0.62). Self-reported mean MET level during the after-school period and the number of 30-min blocks with activity rated at > 6 METs were significantly correlated with the …

The optical transient of the faint gamma-ray burst GRB 990308 was detected by the QUEST camera on the Venezuelan 1 m Schmidt telescope starting 3.28 hr after the burst. Our photometry gives V= 18.32 ± 0.07, R = 18.14 ± 0.06, B = 18.65 ± 0.23, and R = 18.22 ± 0.05 for times ranging from 3.28 to 3.47 hr after the burst. The colors correspond to a spectral slope of close to fv ∝ v1/3. Within the standard synchrotron fireball model, this requires that the external medium be less dense than 104 cm-3, the electrons contain more than 20% …

The Pendulum Swings Again, Richard C. Reuben Oct 1999

The Pendulum Swings Again, Richard C. Reuben

Faculty Publications

Mandatory arbitration provisions in contracts of adhesion expose the difficult tension between individual contractual rights and collective contractual needs. The question is where we draw the line. The law of adhesion contracts has traditionally used the doctrine of unconscionability to draw that line, and cases like Graham v Scissor-Tail more precisely instruct us to draw it at the reasonable expectations of the parties. By presumptively refusing to enforce cram-down arbitration provisions for consumer claims, absent evidence of knowing and voluntary waiver, we will restore those reasonable expectations, and, in the words of the case law, ensure minimum levels of integrity …

High Crimes And Misdemeanors: Defining The Constitutional Limits On Presidential Impeachment, Frank O. Bowman Iii, Stephen L. Sepinuck Oct 1999

High Crimes And Misdemeanors: Defining The Constitutional Limits On Presidential Impeachment, Frank O. Bowman Iii, Stephen L. Sepinuck

Faculty Publications

This Article had its genesis in a statement by the authors submitted to the House Judiciary Committee during its proceedings regarding the impeachment of President Clinton. This final much expanded version appears after the conclusion of the Clinton impeachment proceedings in the Senate, and it is certainly informed by the course those proceedings took. Strictly speaking, however, this is not an article “about” the Clinton impeachment. Although this Article draws some conclusions from the treatment by the House and Senate of the fundamental allegations against President Clinton, it does not address in detail the specific facts underlying those allegations.

(Seven Principles For Good Practice In Legal Education): Principle 5: Good Practice Emphasizes Time On Task, R. Lawrence Dessem Oct 1999

(Seven Principles For Good Practice In Legal Education): Principle 5: Good Practice Emphasizes Time On Task, R. Lawrence Dessem

Faculty Publications

Time plus energy equals learning. Efficient time-management skills are critical for students and professors alike. Allocating realistic amounts of time means effective learning for students and effective teaching for faculty. How an institution defines time expectations for students, faculty, administrators, and other professional staff can establish the basis for high performance for all. The fifth principle for good practice in undergraduate education is almost a truism: good practice emphasizes time on task. In their original statement of the seven principles, Arthur W. Chickering and Zelda F. Gamson expressed this as a mathematical formula: “Time plus energy equals learning.” Time on …

Why In-House Live Client Clinics Won't Work In Romania: Confessions Of A Clinician Educator, Rodney J. Uphoff Oct 1999

Why In-House Live Client Clinics Won't Work In Romania: Confessions Of A Clinician Educator, Rodney J. Uphoff

Faculty Publications

Romanians eat our Big Macs, wolf down pizza slices at Pizza Hut, and guzzle Coca-Cola. They wear baseball caps, Nike clothing, and tennis shoes. They listen to American rap and pop music, see American movies with Romanian subtitles, and watch all of our old television shows. Romanians of all ages, but especially the young, hunger and thirst for all things Western, particularly from the United States. Doesn't it follow, then, that Romanian law schools ought to have - and, indeed, Romanian law professors would want - that symbol of an innovative, modern American law school curriculum: a live client clinical …

Regulation Of Franchisor Opportunism And Production Of The Institutional Framework: Federal Monopoly Or Competition Between The States?, Alan J. Meese Oct 1999

Regulation Of Franchisor Opportunism And Production Of The Institutional Framework: Federal Monopoly Or Competition Between The States?, Alan J. Meese

Faculty Publications

Most scholars would agree that a merger between General Motors and Ford should not be judged solely by Delaware corporate law, even if both firms are incorporated in Delaware. Leaving the standards governing such mergers to state law would assuredly produce a race to the bottom that would result in unduly permissive treatment of such transactions. Similarly, if the two firms agreed to divide markets, most would agree that some regulatory authority other than Michigan or Delaware should have the final word on the agreement. Thus, in order to forestall monopoly or its equivalent, the national government must itself exercise …

Negotiated Development Denial Meets People's Court: Del Monte Dunes Brings New Wildcards To Exactions Law, Jonathan M. Davidson, Ronald H. Rosenberg, Michael C. Spata

Faculty Publications

The United States Supreme Court Answered "YES" to the $1.45 million over exaction question for 1999. In City of Monterey v. Del Monte Dunes at Monterey Ltd., a unanimous court extended the scope of compensatory takings review beyond land dedication conditions into the realm of regulatory denial. Justice Kennedy's opinion vitalized the "legitimate state interests" test from Agins v. City of Tiburon to sustain an inverse condemnation conclusion and damage award to the frustrated developer. A majority of the court also concurred that the trial court may delegate this takings conclusion to the jury under federal civil rights law. The …

Factitious Disorders And Trauma-Related Diagnoses, Daniel Brown, Alan Scheflin

Faculty Publications

The recent plethora of lawsuits involving allegations of iatrogenically implanted memories of satanic ritual abuse and other traumas has highlighted the existence of a unique group of psychiatric patients. Although these patients are often successful at deceiving therapists (and sometimes juries), the case studies in this special issue reveal the chronic nature of their propensity to invent traumatic identities and past histories. The core clinical features of affect dysregulation, somatization, and impaired object relations, together with frequent histories of alcohol and substance abuse, parallel the psychiatric co-morbidity frequently found in genuine trauma victims. These case studies also point to early …

Practical Magic: A Few Down-To-Earth Suggestions For The New Sentencing Commission, Frank O. Bowman Iii

Faculty Publications

Most of the contributions to this outpouring of advice to the new Sentencing Commissioners have to do with the substance of the Guidelines. What follows here is far more prosaic - some suggestions not about what the Commission should do, but about how the Commission should work. I make these suggestions with some trepidation, recognizing the difficulty of the task the new members have undertaken. However, I hope the perspective of one who practiced before and after the Guidelines as a federal prosecutor, participated in the internal workings of the Commission as Special Counsel in 1995-96, and has been a …

Toward The Development Of A Pursuit Decision Calculus: Pursuit Benefits Versus Pursuit Cost, Thomas J. Madden, Geoffrey P. Alpert Oct 1999

Toward The Development Of A Pursuit Decision Calculus: Pursuit Benefits Versus Pursuit Cost, Thomas J. Madden, Geoffrey P. Alpert

Faculty Publications

To make unbiased decisions about whether to pursue a fleeing vehicle, officers must understand both the costs and the potential benefits of a pursuit. This manuscript describes an approach that identifies and assesses the impact of pursuit characteristics on pursuit costs. Data from official pursuit forms generated by officers in the Miami-Dade police department were used as a basis of the study. Log-linear models were used to identify direct and interactive effects of the pursuit characteristics. Upon finding significant effects, odds ratios were calculated. The findings indicate that there are certain pursuit characteristics, including number of units and speed, that …

Desire, Violence, And The Passion In Fragment Vii Of "The Canterbury Tales": A Girardian Reading, Curtis Gruenler Oct 1999

Desire, Violence, And The Passion In Fragment Vii Of "The Canterbury Tales": A Girardian Reading, Curtis Gruenler

Faculty Publications

Part of a special issue on René Girard. The tales of fragment 7 of Chaucer's Canterbury Tales collectively address the problem of human violence and the potential of literature to perpetuate or remedy this problem. The narrative that links the two middles tales of fragment 7 provides a critique of violence that goes beyond mere opposition to war. In this narrative, Chaucer alludes to Christ's crucifixion and death in order to speak as a witness to suffering. In the first three tales of fragment 7—The Shipman's Tale, The Prioress's Tale, and Sir Thopas,—Chaucer depicts the tendencies to mythologize violence in …
