Interval-based robust statistical techniques for non-negative convex functions, with application to timing analysis of computer chips (2006)

In chip design, one of the main objectives is to decrease its clock cycle. On the design stage, this time is usually estimated by using worst-case (interval) techniques, in which we only use the bounds on the parameters that lead to delays. This analysis does not take into account that the probability of the worst-case values is usually very small; thus, the resulting estimates are over-conservative, leading to unnecessary over-design and under-performance of circuits. If we knew the exact probability distributions of the corresponding parameters, then we could use Monte-Carlo simulations (or the corresponding analytical techniques) to get the desired estimates. In practice, however, we only have partial information about the corresponding distributions, and we want to produce estimates that are valid for all distributions which are consistent with this information.In this paper, we develop a general technique that allows us, in particular, to provide such estimates for the clock time.
Efficient Representation and Matching of Texts and Images in Scanned Book Collections (2021)

Trans* identified men have emerged as a growing college and university population in higher education who have not as yet received specific research attention. I studied the experiences of trans* men in higher education and focused on their descriptions of gender identity and the advice they would offer to trans* men (or potential) trans* men about navigating college. With my focus on gender identity I hope to understand the experiences of those men who had, at one time, self-identified or been identified by others as a woman and/or female and who currently identity as man, male, masculine, or trans man. My data came from intensive interviews with 25 trans men who were, at the time of interviews, enrolled in colleges or universities in New England.
Self-starting, passively mode-locked Fabry-Perot fiber soliton laser using nonlinear polarization evolution (1993)

The authors demonstrate pure self-starting mode-locked operation in a fiber Fabry-Perot cavity. The laser produces 1.6 ps transform-limited soliton pulses by means of nonlinear polarization evolution in conjunction with an intracavity fiber polarizer. This laser system can be used for the generation and study of soliton pulses in the picosecond regime. With a careful choice of the fiber dispersion and fiber length, the system should also be able to operate in the femtosecond regime. The advantage of the system over existing self-starting fiber soliton lasers is that an optical isolator (an expensive component) is not required. The replacement of the two mirrors with fiber reflection gratings would make this configuration a truly all-fiber device.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Olfactory dysfunction in multiple sclerosis: association with secondary progression (2011)

A brief odour identification measure provided a good discrimination between SPMS and RRMS courses. A systematic assessment of olfactory functions may contribute to the development of clinical markers of SPMS.
Normal albumin inhibits histone‐induced platelet aggregation (2012)

Histones have been implicated as mediators of death and thrombosis in sepsis, a major cause of mortality in the U.S. The purpose of our study was to define plasma factors that modulate histone‐induced platelet aggregation, which we hypothesize to be albumin. Washed platelets from healthy adults were incubated with various concentrations of human serum albumin, charge‐neutralized albumin (via N‐ethyl‐N′‐(3‐dimethylaminopropyl) carbodiimide hydrochloride), and urea‐denatured albumin and studied using platelet aggregometry in the presence of histone H4 and control. Normal albumin inhibited maximal histone‐induced aggregation in a dose‐dependent manner (0, 2.5, 5, & 10 mg/mL albumin; 57, 28, 20, & 4% aggregation, respectively; p<0.005), while neutralized and denatured albumin lost this inhibitory effect. Furthermore, preliminary data suggest that normal, but not neutralized or denatured, albumin prevents binding of histone H4 to platelets under flow cytometry. These data suggest a role for albumin as an inhibitor of histone‐induced platelet aggregation and may lead to alternative treatment strategies in sepsis.

EBR-II Dry Critical Experiments: Experimental Program, Experimental Procedures and Safety Considerations (1961)

Revisions in the reactor system and operating procedures necessary for carrying out a proposed dry critical experiment in the EBR-II are described. The safety aspect of the program is considered. The critical experiment will be conducted in the EBR-II prior to filling the primary system with sodium. The facility, experimental program, operational and experimental procedures, and hazards and plant safety are described. (M.C.G.)
Interference Competition and Aflatoxin Levels in Corn (1980)

An experiment was designed to determine whether certain fungi commonly isolated from maize at harvest can affect aflatoxin development when inoculated with Aspergillus flavus (NRRL 6412) onto individual sterilized maize kernels (incubation 8 days at 28 deg C). No aflatoxins were detected when A. niger (NRRL 6411) or Trichoderma viride (NRRL 6418) were paired with A. flavus. Aflatoxin contamination was substantial (mean value for B1 ranging from 676 p.p.b. to 3765 p.p.b.) in 11 other simultaneous pairings. When inoculation with A. flavus followed by 5 days that of the other test fungi, aflatoxin was detected only in pairings with Candida guilliermondii (B1, 16 p.p.b.; B2, 1 p.p.b.). However A. flavus invaded a number of the other preinoculated kernels in this series, as evidenced by its abundant sporulation on kernel surfaces and/or the formation of a bright greenish-yellow (BGY) fluorescence in kernel tissues examined under black light (365 nm). The status of individual fungal colonists as interference competitors and the order in which spp. colonize a kernel (i.e. prior to, or simultaneous with, the introduction of A. flavus), are examined as factors contributing to variation in aflatoxin levels among field samples.
Differential time effect profiles of amlodipine, as compared to valsartan, revealed by ambulatory blood pressure monitoring, self blood pressure measurements and dose omission protocol (2004)

Amlodipine and valsartan are once-daily antihypertensive agents. To date, no comparison between these agents given as monotherapies was reported. This study was aimed to evaluate the therapeutic coverage and safety of amlodipine and valsartan in mild-to-moderate hypertensive patients. Multicenter, double-blind, randomized, comparative study. After a 4-week placebo wash-out period, 246 outpatients with office diastolic blood pressure 95 < or = DBP < or =110 mmHg and systolic blood pressure (SBP) < 180 mmHg, in addition to a mean daytime SBP and/or DBP > 135/85 mmHg on 24-h ambulatory blood pressure monitoring (ABPM), were randomly allocated to once-daily amlodipine 5-10 mg or valsartan 40-80 mg, for 12 weeks. In a subgroup of patients, 48-h ABPM were performed at the end of the treatment period. Dose omission was simulated by a single-blind placebo dosing. The primary efficacy end-point was the 24-h trough office BP after 12 weeks of active therapy. The reductions in 24-h trough BP were more pronounced in amlodipine compared with valsartan group as well in office [SBP: -17.8 +/- 10.9 vs. -14.6 +/- 11.2, P = 0.025, DBP: -12.7 +/- 7.2 vs. -10.9 +/- 7.8 mmHg, P = 0.06) as in ambulatory BP (SBP/DBP: -13.0 +/- 13.7/-10.8 +/- 9.1 vs. -7.2 +/- 19.4/-4.9 +/- 13.4 mmHg, P < 0.05). Forty-eight hours after the last active dose, the slope of the morning BP surge (4-9 h) was less steep with amlodipine vs. valsartan [DBP (P < 0.04), SBP (n.s.)]. Ankle edema were more often reported in amlodipine group. These results suggest a superior BP lowering and a longer duration of action with amlodipine compared with valsartan.
A calibration method for measuring thermal expansions with a push-rod dilatometer (2001)

The calibration method for measuring the linear thermal expansion coefficient (LTEC) with a push-rod dilatometer was examined by considering a simple model. To verify the validity of the calibration method, measurements of LTECs for samples of fused silica (SRM 739) and a sample of a single crystal of silicon were carried out with a push-rod dilatometer in the temperature range from room temperature to 973 K. Measurements of melting points of pure metals for temperature calibration, measurement of the sensitivity of a displacement measurement device with a laser interferometer and evaluation of the influence of fluctuations in room temperature on the measured displacement results were also carried out. As a result, the calibrated results of the LTEC for the silicon sample corresponded to the reference value for silicon to within a deviation of ±2% over the measurement temperature range and the validity of the analysis for the push-rod dilatometer was confirmed.
Mechanism of defective NK cell activity in patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex. I. Defective trigger on NK cells for NKCF production by target cells, and partial restoration by IL 2. (1986)

Peripheral blood from patients with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex (ARC) exhibits poor NK activity in the 51Cr-release assay. The present studies were undertaken to investigate the mechanism underlying the observed defective NK cytotoxic activity. On the basis of our studies on the mechanism of natural killer cell-mediated cytotoxicity (NKCMC), a defective NK cell can result from lack or decreased frequency of effector cells, inability to recognize and bind the target cell, failure to be activated for the release of NK cytotoxic factors (NKCF), and/or failure to synthesize or secrete NKCF. Each of these various possibilities was examined. Single cell analysis revealed that the frequency of NK cells was comparable to controls, and although the NK cells bind to the NK-sensitive target, the bound target is not lysed. These results suggested that the defect in NK cells was not due to depletion of NK cells or to a defect in recognition structures, but that it was located at the postrecognition event. We previously demonstrated that after binding to target, the NK cell is stimulated to release NKCF in the supernatants and NKCF lyse specifically NK-sensitive targets. Accordingly, we investigated the activation of NK cells from AIDS and ARC patients for release of NKCF. After coculture with the stimulator cell, the patients' NK cells failed to release active NKCF in the supernatant. However, the cells released NKCF after stimulation with the lectin Con A or a mixture of TPA and ionophore, albeit to a lesser extent than controls. These results suggested that AIDS and ARC NK cells are defective in the trigger involved in release of NKCF. Further studies were done to investigate whether the immunomodulator IL 2 can restore the functional activity of the defective NK cells. Treatment with IL 2 resulted in augmented NK cytolytic activity, but did not reach control levels of activated cells from normal controls. Furthermore, the patients' IL 2-treated cells recover partially the ability to be stimulated by NK cells and to release NKCF. These results suggest that the trigger for NKCF production and the cytolytic function of the patients' NK cells are regulated by IL 2. By delineating the stage at which the AIDS and ARC NK cells are defective, it is now possible to monitor their recovery and to investigate the effect of various biologic response modifiers in restoring NK activity.
Dobutamine Stress Radionuclide Ventriculography Reveals Silent Myocardial Dysfunction in Kawasaki Disease (2002)

Dobutamine (DOB) stress radionuclide ventriculography (RVG) is proposed for evaluating left ventricular performance in patients with Kawasaki disease (KD). Dobutamine stress RVG, up to 15 microg x kg(-1) x min(-1), was performed in 40 patients with a history of KD, some of whom had a perfusion defect (PD group) on dipyridamole stress thallium-201 myocardial imaging, some of whom had no perfusion defects (NPD group), and some of whom had no coronary artery lesions (C group). No significant differences in either systolic or diastolic indices of the left ventricle at rest were observed between the 3 groups. Although hemodynamic responses were similar in all patients after DOB stress, early diastolic index of the first third filling fraction decreased only in the PD group and was significantly lower in this group compared with the C group (p<0.01). The asynchrony index increased significantly in those patients with coronary stenosis after DOB stress (p<0.05). No serious side-effects were observed during the study. Even late after onset, patients with myocardial ischemia as a result of KD still had impaired early diastolic filling and asynchronous relaxation of the left ventricle. As an alternative to exercise testing, DOB stress RVG is a safe and promising means for serially evaluating left ventricular performance in patients with KD.

Anm. av Inger Berg Ørstavik: Innovasjonsspiralen (2012)

Ett patentlicensavtal måste precisera vilken produkt som omfattas av licensen. Ofta anges även att den vidareutveckling av avtalsföremålet som licensgivaren gör ska omfattas av licensen. Om rättighetsinnehavaren upplåter rätt till nyutveckling kan det vara motiverat att licenstagaren på samma sätt bidrar till samarbetet med de uppfinningar som denne kan göra i form av en returlicens – en «grant back». En ganska okomplicerad överenskommelse kan det tyckas. Parterna samverkar på bästa sätt för att dra fördel av den grundläggande uppfinningen. Från en konkurrensrättslig utgångspunkt kan det dock ifrågasättas om saken är så enkel.
Template-Grown Metal Nanowires as Resonators:  Performance and Characterization of Dissipative and Elastic Properties (2007)

Metal resonators can significantly extend the scope of nanoelectromechanical systems (NEMS) through access to a broader range of electrical, thermal, and surface properties. The material behavior of template-electrodeposited gold (Au) and rhodium (Rh) nanowires (NWs) and their performance as resonators was investigated. Nanowire integration by a bottom-up assembly scheme enabled creation of fixed-free metal beams without distortion or tension. Surprisingly, even a soft metal such as Au yielded viable nanocantilever resonators, with Q-factors of 600-950 in high vacuum, while stiffer RhNW had Q-factors of 1100-1300. NWs with diameter approximately 300 nm yield Young's modulus values of 44 +/- 12 GPa for Au and 222 +/- 70 GPa for Rh, both lower than bulk values. This observation is in agreement with two other measurement techniques.
L’évolution et l’apport des chemins de fer secondaires en traction électrique et thermique (automotrices et autorails) (2002)

Il n’en est pas de même en traction, sauf les noms des créateurs ou constructeurs de systèmes complets, tel Decauville, ou de dispositifs pour locomotives à vapeur confrontées avec des courbes de faible rayon, qu’elles soient ou non articulées : ce sont alors, en général, des inventions britanniques, allemandes, ou autrichiennes.

Using Inquiry to Expose Undergraduates to ITS (2014)

In our rapidly evolving world, asking the right questions and properly defining problem boundaries is paramount to successful engineering design. These practices are especially vital for Intelligent Transportation Systems (ITS), which can address a wide range of transportation problems, but which also can exacerbate these same problems. For example, ITS solutions that address the narrowly defined problem of improving traffic flow in an urban area can lead to more regional sprawl, and therefore more traffic and so on-reinforcing a negative feedback loop with ugly results. If the problem is instead framed as trying to reduce commuting times, entirely different and more sustainable ITS solutions may be found. The best planners proceed with caution to avoid prescribing solutions to perceived problems; instead, they take care to understand challenges to urban mobility and the propagating impacts that different development strategies may have. Genuine inquiry, the act of asking questions, ought to be a foundation of engineering education. Indeed, an accumulating amount of engineering education research makes the benefits of such active learning techniques impossible to ignore. Inquiry-based learning begins by posing questions, problems or scenarios in lieu of simply presenting established facts or portraying an existing path to knowledge. It places students' questions, ideas and observations at the center of the learning experience. As students engage with challenges and questions, they achieve higher levels of learning-past the stage of memorizing and reciting data-to more sophisticated methods of analysis, synthesis, and application. The instructor's role is to creatively combine best practices, including explicit instruction, and small-group and guided learning in an attempt to build on students' interests and ideas, ultimately moving students forward in their paths of intellectual curiosity and understanding. This inquiry-based approach is used to introduce a team of Clemson students to the principles and applications of ITS in developing nations.
Lack of evidence to support the association of a single IL28B genotype SNP rs12979860 with the HTLV-1 clinical outcomes and proviral load (2012)
