The Relation between Growth Velocity and Serum Somatomedin C Concentration* (1981)

The relation between serum somatomedin C (SmC) concentration and growth velocity [gain in height (ΔH)] was investigated in five normal children, four GH-deficient (GHD) children, and five girls with Turner syndrome (TS), three of whom had the karyotype 45Χ and two of whom had the karyotype 46, Xi(Xq). At the beginning of the 12-to 20-month study, all subjects were 8-10 yr old. The normal children received no treatment. After a 6-month control period, the GHD group received 0.04 U human GH (hGH)/kg-day for 6 months, then 0.08 U hGH/kg-day for 6 months. The group with TS received during successive 4-month periods: no treatment, oxandrolone (0.125 mg/kg-day), hGH (0.08 U/kg-day), and oxandrolone plus hGH. Serum SmC and height were measured monthly in all subjects. In the normal children, SmC fluctuated between 0.47-3.10 U/ml, with an average of 1.32, and AH varied between 0.0-1.2 cm/ month, with an average of 0.42. SmC and AH were significantly correlated in all children (0.62 < r < 0.92), and were related by the average equation: ΔH = –0.32 + (0.58) (SmC). In GHD children, the mean baseline SmC level was only 0.13 U/ml, and the mean AH only 0.06 cm/month. hGH (0.04 U/kgday) raised these values to 0.46 U////ml and 0.39 cm/month, respectively, and 0.08 U hGH/kg-day caused further increases to 0.88 U/ml and 0.95 cm/month. AH and SmC in GHD children were related by the average equation: AH = –0.09 + (1.27) (SmC). In TS, the average baseline SmC level was normal (0.92 U/ ml), but AH was depressed (0.09 cm/month). Oxandrolone raised these values to 1.29 U/ml and 0.14 cm/month. hGH (0.08 U/kgday) raised SmC to 1.84 U/ml and AH to 0.19 cm/month. Oxandrolone plus hGH had a supraadditive effect on both SmC, which rose to 3.45 U/ml, and on AH, which accelerated to 0.51 cm/month. AH was related to SmC in TS by the average equation: ΔH = –0.11 + (0.18) (SmC). The regression slope of ΔH vs. SmC was significantly greater than normal in GH deficiency and was significantly less than normal in TS, findings which suggest peripheral hyperresponsiveness to SmC in GH deficiency and hyporesponsiveness in TS.
Dynamical tuning of terahertz meta-lens assisted by graphene (2017)

Metasurfaces, which are composed of arrays of scatters, can introduce abrupt change of optical properties. However, they lack flexibility to achieve active control. Here we propose a meta-lens with tunable focal length assisted by graphene at terahertz frequencies. The meta-lens consists of a monolayer graphene and a gold film etched with rectangle apertures with different lengths and rotation angles. By adjusting the gate voltage applied on the graphene layer uniformly, the chemical potential of graphene changes from 0.1 eV to 0.3 eV, and the focal length is changed by 1.25λ continually. This meta-lens is able to concentrate the terahertz beam to a spot size of one wavelength and the focal tuning mechanism works well at incident angles less than 40°.

Cyclization of Globular DNA. Implications for DNA−DNA Interactions in Vivo (1999)

The rate of cyclization of lambda DNA varies over more than 6 orders of magnitude, from 3.2 x 10(-7) s-1 to 2 s-1, in a Tris-EDTA buffer as a function of spermidine concentration. This variation is strictly correlated with the conformation of the chain. The highest rates are obtained when the chain is collapsed into a dense globular state. The effective concentration of the chain ends in the reaction is then 87 000-fold greater than in the random coil state. These results show that DNA globularity must be taken into account to understand biological processes involving intramolecular DNA-DNA interactions.
Incremental, orthorectified and loop-independent mosaicking of aerial images taken by micro UAVs (2011)

In this paper we survey thoroughly the problem of orthorectified and incremental image mosaicking of a sequence of aerial images taken from low-altitude micro aerial vehicles. Most of existing approaches have been exploiting the global optimization (in presence of a loop in the image sequences) to distribute and/or metadata to mitigate the accumulating stitching error. However, the resulting mosaic can be improved if the errors are diminished by studying their sources. Mostly the UAV aerial image mosaicking is affected by the following three important sources of error: i) a weak homography as a result of using unleveled ground control points (GCPs) for image registration, ii) a poor camera calibration and image rectification, and iii) deficiency of a well-defined projection model (cylindrical, planar, etc) and consequently an inappropriate transformation model. We investigate the influences of using a depth map to find the features from the same plane, geometric distortion correction and combining the appropriate choice of projection and transformation model for the mosaicking. We further quantify the improvement of orthorectification in mosaics by mitigating those errors and demonstrate the improvement on real-world mosaics.

Effect of dendrimeric composition on the removal of pyrene from water (2015)

Several closely related branched structures related to the well-established benzyl ether dendrimers were tested as hosts for the removal of pyrene from water. Fluorescence spectroscopy based complexation studies showed that the first generation benzyl ether dendrimers removed on average 94 % of pyrene from a saturated aqueous solution after 30 min. By contrast, branched systems containing modified benzyl ether or cyclohexane functional groups removed between 0 and 75 % of pyrene at the same time point while systems with benzyl amine resulted in a 77 % decrease in pyrene. This selectivity eroded over two days after which time all dendrimeric types removed pyrene to approximately the same extent. Inclusion constants of 10(9)-10(11) M(-1) were calculated for the branched systems studied.
Economic Costs of Diabetes in the U.S. in 2002 (2003)

The estimated 132 billion US dollars cost likely underestimates the true burden of diabetes because it omits intangibles, such as pain and suffering, care provided by nonpaid caregivers, and several areas of health care spending where people with diabetes probably use services at higher rates than people without diabetes (e.g., dental care, optometry care, and the use of licensed dietitians). In addition, the cost estimate excludes undiagnosed cases of diabetes. Health care spending in 2002 for people with diabetes is more than double what spending would be without diabetes. Diabetes imposes a substantial cost burden to society and, in particular, to those individuals with diabetes and their families. Eliminating or reducing the health problems caused by diabetes through factors such as better access to preventive care, more widespread diagnosis, more intensive disease management, and the advent of new medical technologies could significantly improve the quality of life for people with diabetes and their families while at the same time potentially reducing national expenditures for health care services and increasing productivity in the U.S. economy.
Buckled cantilevers for out-of-plane platforms (2008)

In this paper, we show how surface-micromachined buckled cantilevers can be used to construct out-of-plane structures. We include the relevant theory necessary to predict the height and angle of plates attached to buckled cantilevers, as well as the mechanical stresses involved in assembly. These platforms can be assembled to any angle between 0° and 90° with respect to the substrate by changing the attachment point and the amount of deflection. Example devices were fabricated using PolyMUMPs™ and assembled. Using these devices, the deflection of the buckled cantilevers was verified, as well as the placement for raised platforms.
ATTENTIONAL DEMAND AS A MEASURE OF THE INFLUENCE OF VISIBILITY CONDITIONS ON DRIVING TASK DIFFICULTY WITH DISCUSSION (1972)

SIX DRIVERS WERE REQUIRED TO NEGOTIATE A SLALOM COURSE AT AN AUTOMATICALLY CONTROLLED SPEED (30 OR 45 MPH) WHILE WEARING GOGGLES FITTED WITH VARIOUS NEUTRAL- DENSITY FILTERS AND A MOTORCYCLE HELMET WITH A GAS PISTON-OPERATED TRANSLUECENT FACE SHIELD. THE FACE SHIELD COULD BE MOVED FROM ITS NORAMLLY OCCLUDING POSITION FOR A 1/2-SEC LOOK BY MEANS OF A FOOT SWITCH ACCESSIBLE TO THE DRIVER. ATTENTIONAL DEMAND AS MEASURED BY FREQUENCY OF LOOKS INCREASED SIGNIFICANTLY WITH INCREASING GOGGLE DENSITY AT BOTH 30 AND 45 MPH. THE EFFECT OF THE GOGGLES ON ATTENTIONAL DEMAND WAS STRONGER AT 45 THAN AT 30 MPH AND FOR FREQUENTLY LOOKING THAN FOR INFREQUENTLY LOOKING SUBJECTS. WITHIN SUBJECTS (ERROR) VARIABILITY WAS VERY LOW. OTHER MEASURES OF PERFORMANCE WERE NOT INFLUENCED BY THE GOGGLES. IT WAS CONCLUDED THAT ATTENTIONAL DEMAND PROVIDES A MEASURE OF CONTROL TASK DIFFICULTY OR OPERATOR SKILL TO WHICH CONVENTIONAL MEASUREMENTS MAY BE INSENSITIVE.
Parallelizing Compiler Techniques Based on Linear Inequalities (1997)

Shared-memory multiprocessors, built out of the latest microprocessors, are becoming a widely available class of computationally powerful machines. These affordable multiprocessors can potentially deliver supercomputer-like performance to the general public.
To effectively harness the power of these machines it is important to find all the available parallelism in programs. The Stanford SUIF interprocedural parallelizer we have developed is capable of detecting coarser granularity of parallelism in sequential scientific applications than previously possible. Specifically, it can parallelize loops that span numerous procedures and hundreds of lines of codes, frequently requiring modifications to array data structures such as array privatization. Measurements from several standard benchmark suites demonstrate that aggressive interprocedural analyses can substantially advance the capability of automatic parallelization technology.
However, locating parallelism is not sufficient in achieving high performance. It is critical to make effective use of the memory hierarchy. In parallel applications, false sharing and cache conflicts between processors can significantly reduce performance. We have developed the first compiler that automatically performs a full suite of data transformations (a combination of transposing, strip-mining and padding). The performance of many benchmarks improves drastically after the data transformations.
We introduce a framework based on systems of linear inequalities for developing compiler algorithms. Many of the whole program analyses and aggressive optimizations in our compiler employ this framework. Using this framework general solutions to many compiler problems can be found systematically.

Hereditary angioedema with a novel mutation, c.1481G>C, in the SERPING1 gene (2021)

Hereditary angioedema (HAE) is an autosomal dominant disease with recurrent attacks of cutaneous and submucosal swelling caused by mutations in the SERPING1 gene. Here, we report a Japanese case of HAE with a novel mutation in the SERPING1 gene. Accumulation of gene mutations will facilitate the elucidation of HAE pathogenesis and the development of the effective treatments.

EFFECT OF BCG VACCINATION ON MYCOBACTERIUM LEPRAEMURIUM INFECTION IN A HIGHLY SUSCEPTIBLE INBRED MOUSE STRAIN (1981)

Upon infection with Mycobacterium lepraemurium (MLM) C3H mice develop a disease that has features in common with lepromatous leprosy in man. Intraperitoneal vaccination with a single dose of BCG four weeks before inoculation with MLM in the footpad significantly reduced the total bacillary load of the animals. In vaccinated animals there was a delay in the dissemination of bacilli to the popliteal lymph node, liver, and spleen. The growth rate of MLM in the footpad and the popliteal lymph node was not altered by BCG vaccination. Reduced dissemination of the bacilli seems to be a sensitive parameter of resistance in murine leprosy. The mechanism of the resistance observed is discussed mainly in relation to non-specific macrophage activation and T-cell mediated responses to cross-reactive antigens.
Evaluation of Starling forces in the equine digit (1988)

A pump-perfused extracorporeal digital preparation was used to evaluate blood flow, arterial pressure, venous pressure, isogravimetric capillary filtration coefficient, capillary pressure, and vascular compliance in six normal horses. From these data, pre- and postcapillary resistances and pre- and postcapillary resistance ratios were determined. Vascular and tissue oncotic pressures were estimated from plasma and lymph protein concentrations, respectively. By use of the collected and calculated data, tissue pressure in the digit was calculated using the Starling equation. In the isolated equine digit, isogravimetric capillary pressure averaged 36.7 mmHg, plasma and lymph oncotic pressures averaged aged 19.12 and 6.6 mmHg, respectively, interstitial fluid pressure averaged 25.6 mmHg, and the capillary filtration coefficient averaged 0.0013 ml.min-1.mm-1.100 g-1. Our results indicate that digital capillary pressure in the laterally recumbent horse is much higher than in analogous tissues in other species such as dog and human. However, the potential edemagenic effects of this high digital capillary pressure are opposed by at least two mechanisms: 1) a high tissue pressure and 2) a low microvascular surface area for fluid exchange and/or a low microvascular permeability to filtered fluid.

Biocompatible long-circulating star carboxybetaine polymers (2014)

Polyethylene glycol (PEG) is considered to be the most effective material to prolong the circulation time of nanoparticles by reducing non-specific protein adsorption in blood. However, it is recognized that PEG decomposes in most physiological solutions, and an anti-PEG antibody has been detected in some normal blood donors as a response to injection with PEGylated polymer particles. Zwitterionic polymers are potential alternatives to PEG for biomedical applications because of their super resistance to non-specific protein adsorption. Thus, finding one polymer with a long circulation time and resistance to the immune response is of significant importance. Here, we prepared four star carboxybetaine polymers of different molecular weights via atom transfer radical polymerization (ATRP) from a β-cyclodextrin (β-CD) initiator for investigating the biocompatibility of carboxybetaine polymer, a typical zwitterionic polymer. The circulation half-life of the largest star polymer (123 kDa) in mice was prolonged to 40 h in vivo, with no appreciable damage or inflammation observed in the major organ tissues. Furthermore, the circulation time of repeat injections showed similar results to the first injection, with no obvious increase in the amount of antibody in blood. The internalization of the star carboxybetaine polymers by macrophage cells was a relatively slow process. The high cell viability in the presence of star carboxybetaine polymers up to 2 mg mL<sup>-1</sup> was maintained. The hemolytic activity of the star carboxybetaine polymers at 5 mg mL<sup>-1</sup> was almost undetectable. In vitro results prove a key prediction of excellent biocompatibility in vivo. All the results suggest that the carboxybetaine polymer, perhaps even most of the zwitterionic ones, might be a good alternative to PEG in the development of a drug delivery system.
An Optimized Algorithm for Protecting Privacy Based on Coordinates Mean Value for Cognitive Radio Networks (2018)

The cooperative spectrum sensing of cognitive radio networks is quite important in the flexibility of spectrum sharing. The fusion center makes the access decision based on the feedback local sensing information from the secondary users (SUs). However, the local sensing information, which includes the SUs' geographical data, poses a threat to the privacy of those users. Security should be preserved in order to protect the SUs' privacy. In this paper, we aim to preserve the SUs' privacy and propose a location-based privacy protection strategy based on the users' mobile trajectory. The proposed privacy protection algorithm is based on the coordinates mean value, which considers the correlation of various attributes of current privacy protection methods, e.g., the k-anonymity algorithm and the generalization algorithm. The algorithm is optimized by the stochastic gradient descent method to obtain the best performance given different k-values. Simulation results show that the proposed algorithm is effective in terms of the degree of privacy protection, average anonymous time, cost, and loss.
Effect of Cold Rolling Reduction Rate on Secondary Recrystallized Texture in 3%Si-Fe (2011)

The phenomenon of secondary recrystallization in 3%Si-Fe under relatively high cold rolling reduction rate condition has been investigated. The texture of the secondary recrystallized sample under 97.2% cold rolling reduction rate condition consists of {110} orientation, which is quite different from Goss ({110}) orientation obtained under lower cold rolling reduction rate conditions. As a result of Grain Boundary Character Distribution (GBCD) analysis on primary recrystallized texture, {110} orientation has the highest frequency of High Energy (HE) boundary with misorientation angle between 20° and 45°. This result demonstrates that the orientation, which has the highest frequency of HE boundary in primary recrystallized texture, is selected during secondary recrystallization. However, as a result of GBCD analysis based on Coincidence Site Lattice (CSL) boundary, Goss orientation has the highest frequency of S9 (CSL) boundary in the primary recrystallized texture throughout all cold rolling conditions.
The fate of chlorpyrifos‐methyl in stored wheat: A comparison of a laboratory‐scale experiment with a pilot‐scale treatment (1990)

Abstract An experiment was carried out in which a pilot‐scale treatment of a bulk of grain with chlorpyrifos‐methyl was compared with a laboratory treatment of 1 kilogram of grain with 14 C‐radio‐labelled chlorpyrifos‐methyl. The conditions under which the grain was maintained in the laboratory resembled those of the pilot‐scale treatment as closely as possible, with sampling and analysis being carried out at the same time and in a similar manner in both. The results from the two experiments were in general agreement with approximately 60% of the chlorpyrifos‐methyl remaining intact at the end. A satisfactory level of insect control was achieved in the pilot‐scale treatment although it was not possible to assess efficacy in the radiochemical experiment. The use of the radio‐label enabled more information about the fate of the degraded insecticide to be obtained from the laboratory experiment. The majority of this radioactivity comprised a fraction which remained within the grain tissue after solvent extraction. The level of activity in the grain tissues gradually increased with time but its nature is as yet unknown. The good agreement obtained between the residue profile and the breakdown patterns in both experiments would suggest that such a laboratory‐scale experiment can be a satisfactory model for the situation obtaining in a larger‐scale treatment.

Controlling and Minimizing Blistering during T6 Heat Treating of Semi-Solid Castings (2016)

Surface blistering during T6 heat treating is an artifact that is essentially unique to high pressure casting processes such as semi-solid casting and die casting. It is believed that the blistering originates from subsurface defects present in the castings. When the castings are exposed to elevated temperatures during solution heat treatment, the strength of the aluminum is reduced, and the defects expand to deform the surfaces of the castings. There are three potential sources for the subsurface defects - entrapped air, die lubricant or shot sleeve lubricant.This paper will report on a study to determine the origin of the defects present in the castings that produce the blisters. Along with attempting to separate the influence of air and the two types of lubricants on blister formation, the study will also examine the impact of a number of process parameters on blistering.
