Craniofacial Skeletal Measurements Based on Computed Tomography: Part II. Normal Values and Growth Trends (1992)

Current diagnosis and surgical correction of craniofacial anomalies would benefit from accurate quantitative and standardized points of reference. A retrospective study was undertaken to define normal values for a series of craniofacial measurements and to evaluate the growth patterns of the craniofacial complex through axial computed tomography (CT). Fifteen measurements were taken from 542 CT scan series of skeletally normal subjects. The measurement values were then divided into 1-year age categories from 1 to 17 years, and into four age groups for those under 1 year of age. The normal range and growth pattern of measurement values for the cranial vault, orbital region, and upper midface are presented. The overall size of the cranio-orbito-zygomatic skeleton reaches more than 85 percent of adult size by age 5 years. The cranial vault grows rapidly in the first year of life but growth levels off early. The upper midface grows at a slower rate in infancy, but continues to grow later in childhood and early adolescence. Knowledge of the differential growth patterns and normal measurement values in the craniofacial region will help improve diagnostic accuracy, staging of reconstruction, precision of corrective surgery, and follow-up of patients.
A Comprehensive Analysis of XOR-Based Erasure Codes Tolerating 3 or More Concurrent Failures (2013)

In large-scale database storage systems, RAID systems have gained popularity due to their capability to support multiple failures. As data loss is not an option in a system, recent studies focus on erasure codes for the RAID systems, which can tolerate three or more concurrent failures. This paper surveys recent XOR-based erasure codes and presents a comprehensive analysis and comparison among these codes. Moreover, some erasure codes that focus on clustered erasures are also discussed. The paper concludes with open research issues.
ESSENTIALISM AND ISLAM (2017)

We live in an age of polarization.  The political centers in many western societies seem to have vanished.  “Right” and “Left” seem to be pulling further and further apart.  This dichotomy is nowhere more obvious than in the realm of the study of Islam.  Is Islam a religion of peace, or is it a religion of violence?  Are Muslims a terrorist threat, or are they the victims of a hijacking of their religion?  Is the present world-wide struggle the result of western neo-colonialist imperialism or is it the result of Islam’s inherent doctrines.  Are you a follower of Edward Said or are you a follower of Bernard Lewis?  Are the problems we associate with Islam complex or simple?
Designing High-Performance PbS and PbSe Nanocrystal Electronic Devices through Stepwise, Post-Synthesis, Colloidal Atomic Layer Deposition (2014)

We report a simple, solution-based, postsynthetic colloidal, atomic layer deposition (PS-cALD) process to engineer stepwise the surface stoichiometry and therefore the electronic properties of lead chalcogenide nanocrystal (NC) thin films integrated in devices. We found that unlike chalcogen-enriched NC surfaces that are structurally, optically, and electronically unstable, lead chloride treatment creates a well-passivated shell that stabilizes the NCs. Using PS-cALD of lead chalcogenide NC thin films we demonstrate high electron field-effect mobilities of ∼4.5 cm(2)/(V s).
Diabetic retinopathy: loss of neuroretinal adaptation to the diabetic metabolic environment (2014)

Diabetic retinopathy (DR) impairs vision of patients with type 1 and type 2 diabetes, associated with vascular dysfunction and occlusion, retinal edema, hemorrhage, and inappropriate growth of new blood vessels. The recent success of biologic treatments targeting vascular endothelial growth factor (VEGF) demonstrates that treating the vascular aspects in the later stages of the disease can preserve vision in many patients. It would also be highly desirable to prevent the onset of the disease or arrest its progression at a stage preceding the appearance of overt microvascular pathologies. The progression of DR is not necessarily linear but may follow a series of steps that evolve over the course of multiple years. Abundant data suggest that diabetes affects the entire neurovascular unit of the retina, with an early loss of neurovascular coupling, gradual neurodegeneration, gliosis, and neuroinflammation occurring before observable vascular pathologies. In this article, we consider the pathology of DR from the point of view that diabetes causes measurable dysfunctions in the complex integral network of cell types that produce and maintain human vision.

Static and dynamic analysis of a four-tube piezoelectric actuator (2009)

Piezoelectric tubes with film electrodes on their outer and inner surfaces can be used to compose multitube actuators. The actuator of four piezoelectric tubes can substitute the traditional single-tube actuator with quartered electrodes which has been widely used in scanning probe microscopy and piezoelectric motors. In this article, the static deflection, static bending moment, resonant frequency, and dynamic deflection of the four-tube actuator are all studied in detail. The comparison between this actuator and the traditional single-tube actuator is also done and the results show that the four-tube actuator has better performances under certain conditions. The experiment results of a prototype actuator testified the validation of the analysis.
Bixalomer in Hyperphosphatemic Patients With Chronic Kidney Disease Not on Dialysis: Phase 3 Randomized Trial (2016)

Currently, calcium- or metal-containing phosphate binders are available to treat hyperphosphatemia in predialysis patients with chronic kidney disease. Bixalomer, a non-calcium, metal-free phosphate binder, has not been studied in these patients. We evaluated the efficacy and safety of bixalomer versus placebo for treatment of hyperphosphatemia in Japanese predialysis patients with chronic kidney disease. This multicenter, randomized, double-blind, phase 3 trial, randomized eligible patients 1:1 to receive bixalomer or placebo for 12 weeks. Bixalomer was started at 1500 mg/day and adjusted up to 7500 mg/day depending on serum phosphorus concentrations. The primary endpoint was change in serum phosphorus concentration from baseline to end of treatment. After a 4-week pre-investigational period, 163 patients (bixalomer: N = 81; placebo: N = 82) were randomized. The adjusted mean change (95% confidence interval) from baseline to end of treatment in serum phosphorus was significantly greater with bixalomer (-0.78 [-0.98, -0.57] mg/dL) versus placebo (0.20 [-0.00, 0.41] mg/dL); mean difference: -0.98 (-1.27, -0.69), P < 0.001. At end of treatment, 57.5% of bixalomer-treated patients achieved target serum phosphorus concentrations, mean serum intact parathyroid hormone and fibroblast growth factor-23 decreased, and there were no significant changes in corrected serum calcium. The safety and tolerability of bixalomer was similar to placebo. The most common drug-related adverse events were gastrointestinal (>24% patients per group). There was a significant increase in bicarbonate concentrations with bixalomer versus placebo (P = 0.003). Bixalomer was superior to placebo for hyperphosphatemia in Japanese predialysis patients with chronic kidney disease and may constitute a new treatment option.
The Effect of Collisions upon the Doppler Width of Spectral Lines (1953)

Quantum mechanically the Doppler effect results from the recoil momentum changing the translational energy of the radiating atom. The assumption that the recoil momentum is given to the radiating atom is shown to be incorrect if collisions are taking place. If the collisions do not cause broadening by affecting the internal state of the radiator, they result in a substantial narrowing of the Doppler broadened line.
A Novel Current Control System of IPMSM Operating at High Speed based on Model Predictive Control (2007)

This paper describes the novel current control system of interior permanent magnet synchronous motor (IPMSM) based on model predictive control (MPC). Proposed current controller directly selects one of the switching modes of PWM inverter instead of generating voltage reference as conventional one. The problem with selecting the switching mode to output is formulated as MPC problem, considering actual requirements for current control system such as reduction of current error and switching frequency in the steady state. Simulation results show that current transient response improves by proposed current control system, especially at high speed region, where voltage satulation occurs and the inverter operates in overmodulation mode in some cases.
History of the Icon programming language (1996)

The Icon programming language, which was conceived in 1977, was strongly influenced by the earlier SNOBOL languages and the subsequent SL5. This paper concentrates primarily on the early development of Icon, but also discusses subsequent versions. The motivation, design philosophy, and environmental factors that shaped Icon are emphasized in this paper.
<i>In vitro</i> selection for altered divalent metal specificity in the RNase P RNA (1997)

The ribozyme RNase P absolutely requires divalent metal ions for catalytic function. Multiple Mg2+ ions contribute to the optimal catalytic efficiency of RNase P, and it is likely that the tertiary structure of the ribozyme forms a specific metal-binding pocket for these ions within the active-site. To identify base moieties that contribute to catalytic metal-binding sites, we have used in vitro selection to isolate variants of the Escherichia coli RNase P RNA with altered specificities for divalent metal. RNase P RNA variants with increased activity in Ca2+ were enriched over 18 generations of selection for catalysis in the presence of Ca2+, which is normally disfavored relative to Mg2+. Although a wide spectrum of mutations was found in the generation-18 clones, only a single point mutation was common to all clones: a cytosine-to-uracil transition at position 70 (E. coli numbering) of RNase P. Analysis of the C70U point mutant in a wild-type background confirmed that the identity of the base at position 70 is the sole determinant of Ca2+ selectivity. It is noteworthy that C70 lies within the phylogenetically well conserved J3/4-P4-J2/4 region, previously implicated in Mg2+ binding. Our finding that a single base change is sufficient to alter the metal preference of RNase P is further evidence that the J3/4-P4-J2/4 domain forms a portion of the ribozyme's active site.
A Canadian Population Survey on the Clinical, Epidemiologic and Societal Impact of Migraine and Tension-Type Headache (1992)

Trained telephone interviewers contacted 1,573 adults across Canada about the nature and frequency of headaches suffered by them or by others in their households. Using a table of pain symptoms and other characteristics abstracted from the International Headache Society (IHS) classification, the headaches were assigned to migraine headache, tension-type headache or other diagnostic groups. Of the households sampled, 59% had at least one headache sufferer in residence. The proportion of headache sufferers with migraine was 14%; with tension-type, 36%; and with both, 14%. Migraine headache caused more disability than tension-type headache, with nearly 20% of migraine sufferers taking time off work and disability lasting for a mean of 1 day. It is concluded that the current prevalences of migraine and tension-type headache in Canada fall around the mean of previous studies, that the IHS criteria can form a basis for diagnostic classification and that the functional impact of migraine has been seriously underestimated in the past.
Volume Reduction Ratio and Decontamination Factor of the Bench Scale Radwaste Incineration Process (1989)

A bench scale incineration process for the burnable radwaste has been constructed and operated at KAERI as a self-surpported development of incineration technology. The purposes of operating the process are to get experience in incineration, to analyze the characteristics of combustion and to test the performance of off-gas treatment units. Simulated paper and polyethylene wastes were incinerated. Volume reduction ratio and decontamination factor of the process have been determined to observe the economical efficiency and operational capability of the process. A methodology to estimate the acceptance limit of specific activity to an incineration facility by using a decontamination factor and to calculate the volume reduction ratio of the facility is introduced. The acceptance criteria for different radionuclides in the combustible waste at the bench scale incineration process are suggested using this methodology.
A Study of the Forms and Decorative Functions of Beauty Spots (2009)

Literature in beauty art is insufficient regarding beauty spot, though it has played an important role in beauty art history. This study aims at analyzing various patterns and decorative functions of beauty spots and examining their remarkable differences by place and time. It attempts to find the symbolistic characteristics of beauty patch which influenced European countries socially and culturally in the 17th and 18th centuries, findings are as follows: first, beauty spots are extremely various by patch patterns and by forms, e.g. Wha-Jeon(花鈿), Bindi and artificial points. In the view of cosmetic purpose, they have been used to beautify appearances, reveal social positions and express the desires like blessing or protection from evil. In the times of Baroque and Rococo, though temporarily, people with beauty spots and their belonged societies used them as communicative tools: obviously, they functioned symbolistically. This study surveyed 156 persons to find what cosmetic messages and images beauty spots present in the contemporary world. Using SPSS 13.0, the study analyzed the responses and found that beauty spots are still functioning and welcomed to let women look more beautiful and more attractive, though their cosmetic messages and sizes have been simplified and scaled down.
Ethanol‐induced oxidative stress precedes mitochondrially mediated apoptotic death of cultured fetal cortical neurons (2003)

In utero ethanol exposure elicits apoptotic cell death in the fetal brain, and this may be mediated by oxidative stress. Our studies utilize cultured fetal rat cortical neurons and illustrate that ethanol elicits a rapid onset of oxidative stress, which culminates in mitochondrially mediated apoptotic cell death. Cells exposed to ethanol (2.5 mg/ml) remained attached to their polylysine matrix during a 24-hr exposure, but they exhibited distinct signs of oxidative stress, decreased viability, and apoptosis. Confocal microscopy of live cortical neurons pretreated with dichlorodihydrofluorescein diacetate demonstrated an increase in reactive oxygen species (ROS) within 5 min of ethanol exposure. The levels of ROS further increased by 58% within 1 hr (P <.05) and by 82% within 2 hr (P <.05), accompanied by increases of mitochondrial 4-hydroxynonenal (HNE). These early events were followed by decreased trypan blue exclusion of 10% to 32% (P <.05) at the 6- to 24-hr time points, respectively. This culminates in apoptotic death, with increases of Annexin V binding of 43%, 89%, 123%, and 238%, at 2, 6, 12, and 24 hr of ethanol treatment, respectively, as well as DNA fragmentation increases of 50% and 65% by 12 and 24 hr, respectively. Release of cytochrome c by mitochondria increased by 53% at 6 hr of exposure (P <.05), concomitant with activation of caspase 3 (52% at 12 hr, P <.05). Pretreatment with N-acetylcysteine increased cellular glutathione and prevented apoptosis. These studies provide a time line illustrating that oxidative stress and formation of a proapoptotic lipid peroxidation product, HNE, precede a cascade of mitochondrially mediated events in cultured fetal cortical neurons, culminating in apoptotic death. The prevention of apoptosis by augmentation of glutathione stores also strongly supports a role for oxidative stress in ethanol-mediated apoptotic death of fetal cortical neurons.

<title>Heterodyne interferometry using two wavelengths for dimensional measurements</title> (1992)

Optical methods become useful tools for dimensional measurements. Different techniques have been developed in the last few years. In addition to the well known time of flight and phase measuring principles other methods such as focussing and interferometric techniques are implemented. Today, laser interferometry is probably one of the most commonly used interferometric methods in metrology. A stabilized He-Ne laser is freque9tly used as light source with an absolute stability of better than 10 . The accuracy for length measurements is limited by the atmospheric conditions (humidity, temperature, pressure) rather than by the laser stability.
A service framework specification for dynamic e-services interaction (2002)

This paper presents an overview of the concepts involved in implementing a totally inter-operable ecosystem of e-services encompassing both the business-to-business and business-to-consumer domains. These ecosystems integrate such things as supply chain automation, e-procurement, collaborative e-commerce, trading exchanges and personalized business-to-consumer interactions. This paper details the e-speak Service Framework Specification (SFS) and its core API that form the foundation for intelligent interaction amongst e-services in the ecosystem defined above. This paper also addresses some of the cardinal elements of a truly inter-operable ecosystem such as compliance with XML based business process schemas defined by RosettaNet and CommerceNet.
ROBDEKON: Robotic Systems for Decontamination in Hazardous Environments (2019)

Contamination with radioactive or chemical substances can have serious consequences for humans and the environment. For this reason, thorough decontamination is of great importance in the decommissioning of nuclear power plants and the remediation of contaminated sites. People who have to carry out such tasks are working under physically demanding conditions and may be exposed to high health risks. To get humans out of those hazardous environments, the ROBDEKON project was launched with the aim of establishing a national competence center for “Robotic Systems for Decontamination in Hazardous Environments”. In ROBDEKON, four research institutions work together with partners from industry to develop practical robot systems for decontamination tasks. The research activities include the development of mobile robots for rough terrain, autonomous construction machines, and robot manipulators as well as decontamination concepts, planning algorithms, multi-sensory 3D mapping of the environment and teleoperation using virtual reality. The focus is on three applications: the decommissioning of nuclear facilities, the decontamination of plant components and handling of waste, and the remediation of landfills and contaminated sites. This paper gives a high-level overview of the goal and the ongoing research activities in ROBDEKON, provides an insight into the infrastructure of the involved laboratories, and presents first project results.
Birefringent launching fibers for reducing backscattered power fluctuations in polarization-sensitive optical-time-domain reflectometers (1985)

A birefringent launching fiber (BLF) is proposed as a means of reducing backscattered power fluctuations in single-mode fibers that occur during polarization-sensitive measurements. The BLF consists of birefringent single-mode fibers spliced in series. The arrangement of the birefringent single-mode fibers is discussed theoretically and experimentally. Results show the usefulness of the BLF in an optical-time-domain reflectometer.
A Laser Time-of-Flight Range Scanner for Robotic Vision (1983)

The requirements of three-dimensional scene analysis in support of vision driven robotic manipulation are such that direct range finding capabilities can greatly reduce the computational burden (time and complexity) for reliable determination of the placement and spatial extent of objects in the scene. This paper describes a laser time-of-flight range scanner capable of acquiring a reasonable rangepic of 64 × 64 spatial resolution in 4 s. However, at the current state of development, 100 samples/point are required to achieve a range accuracy of approxi-mately ±¿ cm, with a scan time of 40 s. Returned signal amplitude de-pendency is also apparent in the range determination, the dynamic range of intensity being considerable. Improved accuracy can be traded for tine. The vision/robotics laboratory environment within which the range scanner operates is briefly touched upon and some preliminary rangepic results presented.

Liquid Chromatography Tandem Mass Spectrometry Assay for Topiramate Analysis in Plasma and Cerebrospinal Fluid: Validation and Comparison With Fluorescence-Polarization Immunoassay (2002)

The new LC/MS/MS assay has favorable characteristics, being highly precise and accurate. FPIA also proved precise and accurate, and there was a high agreement with the LC/MS/MS assay in plasma and CSF. Either method displayed sufficient precision and accuracy and may thus be implemented in daily routine.
