Measurements to determine the location of the phase center of geoceiver antennas - Unofficial summary of results (1979)

In Doppler positioning systems, the basic method of point positioning involves a stable transmitted satellite signal received by a ground based antenna and receiver. This received frequency is mixed with a locally generated reference frequency, resulting in a beat frequency. A Doppler equation has been developed which includes all known contributions to this Doppler count. Upon measuring this count at the receiver and by using the precise orbital position of the transmitting satellite, the position of a receiver antenna can be calculated. However, for geodetic accuracy, it is assumed that the receiver antenna is stationary and has a predictable constant phase reference point. Thus, if a phase variation does exist, it may be misinterpreted as an added Doppler shift due to range change.
DESIGN OF ON-BOARD COMPUTER SYSTEM FOR KOREAN HIGH-SPEED TRAIN (2000)

Currently, the Korean Electrotechnology Research Institute (KERI) is participating in a project whose goal is to develop the Korean High Speed Train (KHST) a with maximum speed of 350 kph. KERI's responsibility is the electrical system engineering that includes engineering design of an onboard computer system for diagnosis and control of a train set and electrical/mechanical devices. A systems engineering approach of the design is performed in order to guarantee passenger safety and an economically viable train for construction, operation, and maintenance. This paper presents the draft engineering design of an onboard computer system that ensures the safety and reliability of KHST. The draft is focused on a network interfaced distributed processing system.
Surge and Swab Modeling for Dynamic Pressures and Safe Trip Velocities (1983)

Abstract Surge and swab pressures, which could cause lost circulation or gas kicks and blowout, result from running or pulling a pipe in a borehole. Recent downhole measurements indicate that these pressures differ considerably from the pressures anticipated by traditional computational models which compute such pressures on the basis of steady state flow. In this paper, a new dynamic surge and swab model is presented that is based on the physics of the transient nature of the phenomenon. It treats friction as a distributed parameter and considers various parameters in hole geometry, hole expansion, varying trip velocity, return area for tricone and diamond drill bits, plugged jets, and the mud properties. The computer program for the model not only predicts the maximum surge and swab pressures or their variation with time at various points in the borehole, but also computes the safe maximum trip speed for a specified pressure margin. Computer studies for running a casing, liner, and drill string in several actual wells show the model to have fast computer run times. The results of some of these studies are reported in the paper. The program is both interactive and user-friendly, and is a significant improvement over the existing models.

Before the final bibliography there are sorted reference lists to the literature by geological age, relevant country, and by subject according to the main thrust of the article.
The Role of Therapeutic Drugs on Acquired Mitochondrial Toxicity (2016)

Since treatment of acquired mitochondriopathies remains supportive and therapeutic interventions cannot be avoided, information of molecular and clinical consequences of toxic exposure becomes fundamental to assess riskbenefit imbalance of treatment prescription. Additionally, there is a crucial need to develop less mitochondrial toxic compounds, novel biomarkers to follow up mitochondrial toxicity (or implement those already proposed) and new approaches to prevent or revert unintended mitochondrial damage.
Novel Phosphorescent Cyclometalated Organotin(IV) and Organolead(IV) Complexes of 2,6-Bis(2‘-indolyl)pyridine and 2,6-Bis[2‘-(7-azaindolyl)]pyridine (2003)

Four novel five-coordinated Sn(IV) and Pb(IV) complexes of 2,6-bis(2‘-indolyl)pyridine (H2bip) and 2,6-bis[2‘-(7-azaindolyl)]pyridine (H2bap) were synthesized. These four complexes have the formulas Sn(bip)Ph2 (1), Sn(bap)Ph2 (2), Pb(bip)Ph2 (3), and Pb(bap)Ph2 (4), respectively. The structures were determined by single-crystal X-ray diffraction. In the complexes, the metal centers are tridentately chelated by the bip or the bap ligand and further coordinated by two phenyl groups, resulting in a distorted-trigonal-bipyramidal geometry. These complexes display interesting extended π−π stack structures in the solid state. Complexes 1 and 2 are luminescent at room temperature in solution and the solid state. At 77 K in THF solution, all four complexes display both blue-green fluorescent and orange-red phosphorescent emissions, which originate from ligand-centered π → π* transitions. The Sn(IV) and Pb(IV) centers play a key role in enhancing phosphorescent emission of the bip and bap ligands.
Infectious diseases specialist management improves outcomes for outpatients diagnosed with cellulitis in the emergency department: a double cohort study (2017)

Three hospital emergency rooms (ERs) routinely referred all cases of cellulitis requiring outpatient intravenous antibiotics, to a central ER-staffed cellulitis clinic. We performed a retrospective cohort study of all patients seen by the ER clinic in the last 4months preceding a policy change (ER management cohort [ERMC]) (n=149) and all those seen in the first 3months of a new policy of automatic referral to an infectious disease (ID) specialist-supervised cellulitis clinic (ID management cohort [IDMC]) (n=136). Fifty-four (40%) of 136 patients in the IDMC were given an alternative diagnosis (noncellulitis), compared to 16 (11%) of 149 in the ERMC (P<0.0001). Logistic regression-demonstrated rates of disease recurrence were lower in the IDMC than the ERMC (hazard ratio [HR], 0.06; P=0.003), as were rates of hospitalization (HR, 0.11; P=0.01). There was no significant difference in mortality. Automatic ID consultation for cellulitis was beneficial in differentiating mimickers from true cellulitis, reducing recurrence, and preventing hospital admissions.
Clinical Challenges in a Prison Rheumatology Referral Practice (2003)

The objective of this study was to describe 100 consecutive patients evaluated by a consultative rheumatology service at the California Medical Facility, a 3,300-bed adult male correctional medical facility in Northern California. Methods entailed review of a database containing the first 100 consultations performed by the rheumatology service. Age, ethnicity, and diagnosis were recorded. Results: Age ranged from 24 to 78 years, with a mean of 44 years. Ethnic breakdown was 40% White, 36% Black, 18% Hispanic, 1% Native American, and 1% "other." The most common diagnoses were osteoarthritis (27%), ankylosing spondylitis (8%), normal examination (6%), internal derangement of the knee (5%), and gout (4%). A variety of conditions were found in 3% or less of the patients seen, ranging from polymyositis to spinal osteomyelitis. Study conclusions are that rheumatology patients in prison may be young or old, are ethnically diverse, and manifest broad-ranging pathology. Osteoarthritis is the most common diagnosis, perhaps due to traumatic injuries often described by incarcerated persons.
Pretreatment Regimens for Adverse Events Related to Infusion of Amphotericin B (1995)

Infusion-related adverse events (IRAEs) such as nausea, vomiting, fever, chills, and thrombophlebitis that are associated with amphotericin B therapy often lead clinicians to prescribe a number of adjunctive pretreatment medications in an attempt to reduce the incidence and severity of these events. The purpose of this study was to determine the incidence of IRAEs during the first week of systemic amphotericin B therapy and to identify pretreatment regimens that are effective in preventing these IRAEs. Three hundred ninety-seven adult inpatients receiving amphotericin B therapy were prospectively monitored, and data regarding IRAEs and pretreatment regimens were collected. Of these patients, 282 (71%) developed at least one IRAE during the first 7 days of therapy. The IRAEs most commonly reported were fever (51% of patients) and chills (28%), followed by nausea (18%), headache (9%), and thrombophlebitis (5%). The most common regimens included diphenhydramine, a corticosteroid, acetaminophen, and heparin, administered alone or in combination with these or other drugs. Overall, common pretreatment regimens were similar in efficacy to no pretreatment in the prevention of IRAEs. Thus empirical premedication for IRAEs associated with amphotericin B cannot be routinely advocated; instead, patients should be treated when symptoms first arise and then premedicated for subsequent amphotericin B infusions.
Carbon–carbon bonding made easy (2005)

The palladium-catalyzed cross-coupling reaction between organoboranes and organic electrophiles in the presence of base was first developed 30 years ago. It offers a powerful and general methodology for forming carbon-carbon bonds. The scope of the reaction has continued to evolve and broaden to meet modern synthetic requirements.

The <i>Laws</i>' two projects (2011)

Plato's Laws has probably been the most unpopular of all his dialogues. ‘Not only’, says the Loeb editor in his introduction, ‘does it lack the charm and vigour of the earlier dialogues, but it is marked also by much uncouthness of style, and by a tendency to pedantry, tautology and discursive garrulity which seems to point to the failing powers of the author.’ It represents itself as the record of a rambling conversation, ‘framed apparently on no artistic plan’, between three elderly men, who get immersed in masses of detail often of little general philosophical interest. Damning remarks of this and other kinds can be found without difficulty in modern literature about Plato.
Habitat Use by Breeding Northern Bobwhites in Managed Old-Field Habitats in Mississippi (2017)

To better understand the proximate and ultimate cues associated with habitat selection in breeding northern bobwhites (Colinus virginianus), we compared habitat use vs. availability at 2 spatial scales equivalent to Johnson's (1980) 2nd and 3,d order selection. We conducted the study in managed old-field habitats in Mississippi, from 1994 to 1996. We also estimated habitat use by broods with respect to availability, and quantified micro-habitat characteristics (4th order selection) at brood-rearing sites and nesting sites. Breeding bobwhites did not establish home ranges at random or allocate resources among patches in proportion to their availability. Breeding bobwhites, given a mosaic of seasonally manipulated old-field habitats, consistently used burned fields, disked fields, and areas with advanced woody succession to define breeding season home ranges. Bobwhites allocated their time and resources more to woody areas and fields that had received a combination of burning and disking. Broods consistently used burned/disked fields in proportion to availability; consistently avoided row crops and pastures; and generally preferred woody corridors. Vegetation characteristics at nest sites did not differ from random sites located within the same patch of habitat. Characteristics among nest sites were similar, yet successful nests were located in the proximity of more bare ground and less litter cover than unsuccessful nest sites. Brood site habitat characteristics were similar to nest sites; however, woody canopy (44.3%) and visual obstruction readings (59.0cm) at brood sites were significantly greater than nest sites (26.6% and 32.5cm).
Hemodynamic Effects of Epinephrine in Healthy and Hemorrhagic Shock Rats (2011)

Epinephrine 2 μg/kg intravenous injection elicited biphasic changes in blood pressure, which included an initial increase and a subsequent decrease in healthy rats and induced a remarkable increase in blood pressure in hemorrhagic shock rats.
Effects of initial fiber length and fiber length distribution on the properties of carbon-fiber-reinforced-polypropylene composites (2012)

In this study, short carbon fiber-reinforced polypropylene composites with three different initial carbon fiber lengths were prepared by using extrusion compounding and injection molding techniques. The physical and morphological properties of the prepared short carbon fiber-reinforced composites were investigated by means of tensile test, differential scanning calorimetry and scanning electron microscopy. Final fiber length distributions of composites were also determined by using an image analyzing program. It was found that the maximum number of fibers was observed in the range from 51 to 100 µm. Number average final fiber lengths were calculated between 230 and 280 µm. Regardless of the used initial carbon fiber length, tensile strength and modulus values of the composites increased with the increasing carbon fiber content. It has been concluded that the initial fiber length at the studied range did not have any significant effect on the properties of composites.
Accurate Assessment of Short-Term Suicide Risk in a Crisis (1994)

The majority of studies in the field of suicide assessment describe the characteristics of patients with suicidal ideation, rather than focusing on characteristics of those who commit suicide.
Implementation of Uncertainty Propagation in TRITON/KENO: To Support the Global Nuclear Energy Partnership (2007)

Monte Carlo methods are beginning to be used for three-dimensional fuel depletion analyses to compute various quantities of interest, including isotopic compositions of used fuel.1 The TRITON control module, available in the SCALE 5.1 code system, can perform three dimensional (3-D) depletion calculations using either the KENO V.a or KENO-VI Monte Carlo transport codes, as well as the two-dimensional (2- D) NEWT discrete ordinates code. For typical reactor systems, the neutron flux is not spatially uniform. For Monte Carlo simulations, this results in non-uniform statistical uncertainties in the computed reaction rates. For spatial regions where the flux is low, e.g., axial fuel ends, computed quantities, such as isotopic compositions, may have large statistical uncertainties. However, in currently available Monte Carlo depletion codes these statistical uncertainties are not calculated or reported to the user. Consequently, users have no indication of the fidelity of their results in such regions, which can be a significant impediment to the effective use of Monte Carlo methods for design and optimization studies of advanced fuel designs. Additionally, for applications such as criticality safety of used nuclear fuel, the lower depleted end regions tend to dominate the reactivity, and hence must be accurately and/or conservatively represented.
Transplantation of Corneal Endothelial Cells Using a Cell Carrier Device (1994)

Penetrating keratoplasty is currently the only treatment for corneal endothelial dysfunction. Although corneal transplantation has a high success rate, a few problems still remain, such as the limited availability of donor grafts, the change in refraction after penetrating keratoplasty, and the higher chance of immune rejection. In this study, a coated hydrogel lens (Chiron Ophthalmics Inc., Irvine CA, U.S.A.) has been used as a carrier to transplant cultured homologous kitten and rabbit corneal endothelial cells into adult cats and rabbits. The transplantation procedure was the same in both species. Corneal endothelial cells from homologous rabbits or cats were seeded on coated hydrogel lenses and cultured until they reached a complete monolayer with an average cell density of 2,500 cells/mm2. Five weeks before transplantation surgery, corneal endothelial cells were scraped to induce corneal edema. The cell carrier device was then transplanted as follows: a trephine cut (7.7 mm) was made into the stroma, producing an outer corneal plug. The inner cornea was then cut by using a 5.5-mm trephine, and this inner plug was discarded. The implant was inserted and the outer corneal plug was sutured back into place. Corneas cleared completely within 3 days in both rabbits and cats, and stayed clear for an average of 40 days in rabbits and 50 days in cats. The histopathological evaluation of the rejected grafts showed vascularized retrocorneal membrane formation in cats, whereas in rabbits severe cellular infiltration of the stroma with neovascularization occurred without retrocorneal membrane formation.
Proportional fair scheduling for multi-cell multi-user MIMO systems (2010)

In this paper, a multi-cell multi-user MIMO scheme with advanced user pairing and scheduling algorithm is proposed to effectively explore multi-user diversity and to combat both intra-cell and inter-cell interference in the downlink of wireless communication systems. The optimality of the proposed user paring and scheduling algorithm is shown under generalized proportional fair metrics. System-level simulations are conducted to verify the performance of the proposed scheme with the agreed LTE-Advanced (LTE-A) system parameters. The results suggest the proposed scheme is a promising candidate for improving both the cell-edge user throughput and average cell throughput, and furthermore for fulfilling the IMT-Advanced (IMT-A) requirements.
<title>Schottky Diode Based Infrared Sensors</title> (1983)

Suicide Schottky diode based infrared cameras have received wide interest recently because they are easy to manufacture, non-complex and have excellent performance. In this paper we will describe the operation of Schottky cameras, point out the physical basis of their unique properties and report on the current status of this technology.
Channel temperature measurement using pulse-gate method [power amplifier FET] (1999)

In this paper, we report on an approach of measuring power amplifier field-effect transistor (FET) channel temperature under real-world operating conditions. The principle of this approach is to compare the magnitude of power amplifier gain at both DC and pulse bias conditions. By utilizing the temperature-dependent gain characteristic of the power amplifier FET and applying pulse-gate control, the gain would gradually decrease with the rising temperature of the hot plate. The channel temperature is then determined when the decreasing gain reaches the level of the base line, which is measured under the specified DC bias and radiofrequency conditions.
High-Strength, Tough, and Self-Healing Nanocomposite Physical Hydrogels Based on the Synergistic Effects of Dynamic Hydrogen Bond and Dual Coordination Bonds (2017)

Dynamic noncovalent interactions with reversible nature are critical for the integral synthesis of self-healing biological materials. In this work, we developed a simple one-pot strategy to prepare a fully physically cross-linked nanocomposite hydrogel through the formation of the hydrogen bonds and dual metal-carboxylate coordination bonds within supramolecular networks, in which iron ions (Fe<sup>3+</sup>) and TEMPO oxidized cellulose nanofibrils (CNFs) acted as cross-linkers and led to the improved mechanical strength, toughness, time-dependent self-recovery capability and self-healing property. The spectroscopic analysis and rheological measurements corroborated the existence of hydrogen bonds and dual coordination bonds. The mechanical tests and microscopic morphology were explored to elucidate the recovery properties and toughening mechanisms. The hydrogen bonds tend to preferentially break prior to the coordination bonds associated complexes that act as skeleton to maintain primary structure integrity, and the survived coordination bonds with dynamic feature also serve as sacrificial bonds to dissipate another amount of energy after the rupture of hydrogen bonds, which collectively maximize the contribution of sacrificial bonds to energy dissipation while affording elasticity. Additionally, the multiple noncovalent interactions in diverse types synergistically serve as dynamic but highly stable associations, leading to the effective self-healing efficiency over 90% after damage. We expect that this facile strategy of incorporating the biocompatible and biodegradable CNFs as building blocks may enrich the avenue in exploration of dynamic and tunable cellulosic hydrogels to expand their potential applications in the biomedical field.
Creating Anatomically Accurate and Reproducible Intracranial Xenografts of Human Brain Tumors (2014)

Orthotopic tumor models are currently the best way to study the characteristics of a tumor type, with and without intervention, in the context of a live animal - particularly in sites with unique physiological and architectural qualities such as the brain. In vitro and ectopic models cannot account for features such as vasculature, blood brain barrier, metabolism, drug delivery and toxicity, and a host of other relevant factors. Orthotopic models have their limitations too, but with proper technique tumor cells of interest can be accurately engrafted into tissue that most closely mimics conditions in the human brain. By employing methods that deliver precisely measured volumes to accurately defined locations at a consistent rate and pressure, mouse models of human brain tumors with predictable growth rates can be reproducibly created and are suitable for reliable analysis of various interventions. The protocol described here focuses on the technical details of designing and preparing for an intracranial injection, performing the surgery, and ensuring successful and reproducible tumor growth and provides starting points for a variety of conditions that can be customized for a range of different brain tumor models.
