Cement supplementation as a treatment for osteonecrosis (2003)

Treatment for femoral head osteonecrosis has been less successful in late stages of the disease, after progression to collapse. Several treatment techniques have been reported, however, no single approach has been convincingly successful. Ideally, the goal is to prevent additional collapse and restore femoral head sphericity. Bone grafting techniques predictably halt progression in early stages, but have been less successful at joint restoration once collapse occurs. After collapse, the sphericity of the femoral head may be restored by debriding the necrotic zone then elevating and supporting the collapsed segment by the injection of cement. Cementation is technically simple, ensures the patient immediate postoperative pain relief and improvement in early mobility, and has the potential to restore and maintain the sphericity of the femoral head after collapse. The procedure has low morbidity and does not compromise subsequent revision to total hip arthroplasty.

Magnesium Metabolism (1968)

Transition-metal impurities in semiconductors and heterojunction band lineups (1988)

The validity of a recent proposal that transition-metal impurity levels in semiconductors may serve as a reference in band alignment in semiconductor heterojunctions is positively verified by using the most recent data on band offsets in the following lattice-matched heterojunctions: ${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Al}}_{\mathrm{x}}$As/GaAs, ${\mathrm{In}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Ga}}_{\mathrm{x}}$${\mathrm{As}}_{\mathrm{y}}$${\mathrm{P}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$/InP, ${\mathrm{In}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Ga}}_{\mathrm{x}}$P/GaAs, and ${\mathrm{Cd}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Hg}}_{\mathrm{x}}$Te/CdTe. The alignment procedure is justified theoretically by showing that transition-metal energy levels are effectively pinned to the average dangling-bond energy level, which serves as the reference level for the heterojunction band alignment. Experimental and theoretical arguments showing that an increasingly popular notion on transition-metal energy-level pinning to the vacuum level is unjustified and must be abandoned in favor of the internal-reference rule proposed recently [J. M. Langer and H. Heinrich, Phys. Rev. Lett. 55, 1414 (1985)] are presented.
Peripheral Vasodilatation after Spinal Cord Stimulation: Animal Studies of Putative Effector Mechanisms (1991)

Spinal cord stimulation has been reported to relieve ischemic pain and to enhance peripheral circulation. To elucidate the still unknown mechanisms behind these effects, changes in the peripheral blood flow in the skin of the hind paw after stimulation applied to the dorsal column was studied in the normal rat. A substantial flow increase, monitored by laser Doppler technique, was observed in response to stimulation with an intensity comparable to that used clinically in man, recruiting only low-threshold neuronal elements. The response remained after transection of the dorsal roots, as well as after spinal cord section rostrally to the stimulating electrode. Furthermore, monitoring of antidromic compound action potentials in a peripheral nerve indicated that the stimulus intensity applied to dorsal columns recruited solely low-threshold, large-diameter fibers. Stimulation failed to produce an increase in blood flow in addition to that produced by guanethidine and hexamethonium, but high-intensity dorsal column or dorsal root stimulation still was effective. The results indicate that spinal mechanisms are essential and that antidromic activation of primary afferent fibers is unlikely to account for the peripheral vasodilatation induced by low-intensity spinal cord stimulation. Our observations suggest a transitory inhibition of sympathetic vasoconstriction as the principal underlying mechanism.
An Analysis of Human Motion Detection Systems Use During Elder Exercise Routines (2010)

Human motion analysis provides motion pattern and body pose estimations. This study integrates computer-vision techniques and explores a markerless human motion analysis system. Using human-computer interaction (HCI) methods and goals, researchers use a computer interface to provide feedback about range of motion to users. A total of 35 adults aged 65 and older perform three exercises in a public gym while human motion capture methods are used. Following exercises, participants are shown processed human motion images captured during exercises on a customized interface. Standardized questionnaires are used to elicit responses from users during interactions with the interface. A matrix of HCI goals (effectiveness, efficiency, and user satisfaction) and emerging themes are used to describe interactions. Sixteen users state the interface would be useful, but not necessarily for safety purposes. Users want better image quality, when expectations are matched satisfaction increases, and unclear meaning of motion measures decreases satisfaction.

We report electroreflectance spectra for a series of ${\mathrm{GaAs}}_{1\ensuremath{-}x}{\mathrm{N}}_{x}$ samples with $x<0.03$. For all samples, the fundamental band gap transition $({E}_{0})$ and the transition from the spin-orbit split-off valence band $({E}_{0}+{\ensuremath{\Delta}}_{0})$ are observed. For samples with $x\ensuremath{\ge}0.008$, an additional transition $({E}_{+})$ is observed. With increasing nitrogen content, the increase in ${E}_{+}$ is linear in, and nearly equal to, the band gap reduction indicative of a nitrogen-induced level repulsion. The directly observed ${E}_{+}$ transition may arise from either a nitrogen-related resonant level or a disorder-activated indirect transition.
Comparison of the antigenicity and tolerance of an influenza aluminium oxide adsorbate vaccine with an aqueous vaccine. (1982)

A randomized trial was carried out in 189 adult subjects to test the antigenicity and tolerance of two experimental influenza vaccines, one adsorbed onto aluminium oxide and the other one aqueous, with equal antigen contents. Blood samples for antibody assays, using the haemagglutination inhibition test and the neuraminidase inhibition test, were taken before and 30, 90 and 180 days after vaccination. The results showed that the adsorbate influenza vaccine had a superior immunogenic action to the aqueous vaccine at the same dose rate. There were no significant differences between the tolerances of the two vaccines, which were injected with a needle. About 81% of the vaccinated subjects showed no subjective or objective signs of intolerance. Systemic reactions, which were reported by 9% of the vaccinated subjects, were verified by the doctor in only 2% of cases.
On the Security of Tenant Transactions in the Cloud (2013)

Cloud computing technologies are receiving a great deal of attention. Although there are several benefits with the cloud, the attackers can also use the cloud infrastructure for hosting malicious services and generating different types of attacks. In this paper we propose techniques for securing tenant transactions in the cloud.
Response to Comment on “Enhanced water permeability and tunable ion selectivity in subnanometer carbon nanotube porins” (2018)

Horner and Pohl argue that high water transport rates reported for carbon nanotube porins (CNTPs) originate from leakage at the nanotube-bilayer interface. Our results and new experimental evidence are consistent with transport through the nanotube pores and rule out a defect-mediated transport mechanism. Mechanistic origins of the high Arrhenius factor that we reported for narrow CNTPs at pH 8 require further investigation.
A framework for practical parallel fast matrix multiplication (2015)

Matrix multiplication is a fundamental computation in many scientific disciplines. In this paper, we show that novel fast matrix multiplication algorithms can significantly outperform vendor implementations of the classical algorithm and Strassen's fast algorithm on modest problem sizes and shapes. Furthermore, we show that the best choice of fast algorithm depends not only on the size of the matrices but also the shape. We develop a code generation tool to automatically implement multiple sequential and shared-memory parallel variants of each fast algorithm, including our novel parallelization scheme. This allows us to rapidly benchmark over 20 fast algorithms on several problem sizes. Furthermore, we discuss a number of practical implementation issues for these algorithms on shared-memory machines that can direct further research on making fast algorithms practical.
Charging effect and capacitance modulation of Ni-rich NiO thin film (2009)

In this letter, Ni-rich NiO thin film is deposited on p-type Si substrate by dc magnetron sputtering to form a metal-insulator-semiconductor structure. The charge trapping in the Ni nanocrystals (nc-Ni) embedded in NiO matrix induces a flatband voltage shift and capacitance modulation, which could be used for memory applications. The charging of nc-Ni depends on the voltage polarity, as well as the charging time and magnitude of gate voltage. The capacitance modulation can be described by an equivalent circuit model.

Effective principal refractive indices and column angles for periodic stacks of thin birefringent films (1993)

An effective medium theory is developed for periodic stacks of thin films A and B, one or both of which may be birefringent because of an effect such as columnar microstructure. The equivalent medium is itself described as columnlike, and the theory permits calculation of the angle of the effective columns together with the magnitudes of the effective principal refractive indices. Several examples that relate to possible applications of the method are discussed, and it is shown that optical media with predetermined refractive indices and birefringence may be engineered. For example, the layered combination of a low-index material A with zero or small normal-incidence refractive anisotropy and a high-index material B with large anisotropy may be used to make a medium-index material with considerable normal-incidence anisotropy.

OSHA's bloodborne pathogens rule an opportunity/threat. (1992)

If you supply healthcare linen, OSHA's new ruling comes with a price tag, but it may be a marketing boon as well. The costs of compliance are high--about $1.19 million annually. One of the most costly and important parts of the ruling is the required employer-paid hepatitis B vaccination of employees. But behind the costs, there's good news for the textile rental industry. The opportunity to serve small medical facilities and nursing homes as well as hospitals with reusable healthcare garments could create a revenue source estimated to be at least $177 million a year.
Narrow-band indoor measurement of the sound power of a complex mechanical noise source (1990)

There is a need to develop practical standard sound-power tests for manufactured products independent of the test location. That it is possible to develop such standards, for use in a normal work area, has been demonstrated in tests with six light vehicles. The sound power of each vehicle was measured for different engine speeds and loads using a semicircular array of sound-intensity probes rotated over a hypothetical, hemispherical surface enclosing the vehicle running on a dynamometer roll. The presence of the walls and ceiling of the work area appears to have a negligible effect on A-weighted sound-power measurement. Good agreement was obtained with the overall sound power of a standard reference source. Results for the six vehicles indicate that the peaks in the narrow-band sound-power spectra occur at frequencies corresponding to the orders of excitation of components of the vehicle power train. This has diagnostic value because it identifies noisy components and provides a quantitive measure of their contribution to the total sound power of the vehicle. It could also be used to detect malfunctioning and wear of components.
Effect of Carbon Dioxide Immobilization on the Bleeding of Chickens (1957)

INTRODUCTION MANY processors believe that the improvement of the meat type birds through breeding and high carbohydrate and low protein feeding has resulted in slower and less complete bleeding of the birds at slaughter. This, coupled with accelerated processing procedures, has resulted in increased percentages of poorly bled and misbled carcasses. A number of investigators have worked for remedies. They studied the effects of various degrees of starving prior to sticking, Baker, Margolf and Callenbach (1950); the use of various sticking techniques, Newell and Shaffner (1950); Davis and Coe (1954); the injection of epinephrine into the veins, the treatment of birds with high concentrations of oxygen, Newell and Shaffner (1950a); the feeding of special rations to birds, Turner (1948); and the influence of electric shock, Mountney, Gardner and Gayvert (1956). Other researchers in working to improve slaughtering methods for use on mammals, reportedly have been successful in improving bleeding by . . .
A Model With a Heuristic Algorithm for Solving the Long-Term Many-to-Many Car Pooling Problem (2011)

Long-term car pooling is defined as the sharing of a private vehicle by more than one user who need to reach a destination following a semicommon route between the individuals' points of origin and destination in a specific period. In this paper, we employ a network flow technique to systematically develop a long-term many-to-many car pooling model. The model is formulated as a special integer multiple-commodity network flow problem. A Lagrangian relaxation-based algorithm is also developed to solve the model. The performance of the heuristic algorithm is evaluated by carrying out a case study using real data and suitable assumptions. The test results confirm the usefulness of the model and the heuristic algorithm and that they could be useful in practice.
Cross-linked polyacrylamide gel electrophoresis of single-stranded DNA for microfabricated genomic analysis systems (2002)

Microfabricated devices are poised to offer inexpensive self-contained alternatives to conventional benchtop-scale laboratory equipment for performing a variety of important DNA analysis assays. In order to realize the dramatic cost savings possible through photolithographic fabrication techniques, these devices must occupy an extremely compact footprint on the silicon wafer. This requirement implies that electrophoretic separations must be performed over ultrashort distances. Employing cross-linked polyacrylamide gels in place of conventional uncross-linked sieving media offers a convenient strategy to achieve this goal. In this paper, we show how the increased resolving power offered by cross-linked polyacrylamide gels, along with improved sample injection techniques, can be exploited to enhance separation performance in microscale systems. We use these techniques to perform high-resolution gel electrophoresis of single-stranded DNA fragments in microfabricated devices over separation distances of 1.5 cm or less. The results presented here are in agreement with theoretical predictions and suggest that it is possible to perform DNA sequencing on compact microchips. More importantly, the separation performance demonstrated in this work is already more than adequate to perform a number of important genomic assays imposing less stringent resolution requirements than sequencing. Successfully adapting even a few of these assays to the microdevice format has the potential to provide a new generation of inexpensive and portable devices suitable for direct end-user applications.
The TP53 website: an integrative resource centre for the TP53 mutation database and TP53 mutant analysis (2012)

A novel resource centre for TP53 mutations and mutants has been developed (http://p53.fr). TP53 gene dysfunction can be found in the majority of human cancer types. The potential use of TP53 mutation as a biomarker for clinical studies or exposome analysis has led to the publication of thousands of reports describing the TP53 gene status in >10,000 tumours. The UMD TP53 mutation database was created in 1990 and has been regularly updated. The 2012 release of the database has been carefully curated, and all suspicious reports have been eliminated. It is available either as a flat file that can be easily manipulated or as novel multi-platform analytical software that has been designed to analyse various aspects of TP53 mutations. Several tools to ascertain TP53 mutations are also available for download. We have developed TP53MULTLoad, a manually curated database providing comprehensive details on the properties of 2549 missense TP53 mutants. More than 100,000 entries have been arranged in 39 different activity fields, such as change of transactivation on various promoters, apoptosis or growth arrest. For several hot spot mutants, multiple gain of function activities are also included. The database can be easily browsed via a graphical user interface.
