Long-range propagation tests of a 200-Hz sound source for ocean acoustic tomography (1994)

A 200-Hz low-frequency sound source for ocean acoustic tomography was developed by using a supermagnetostrictive material made of the rare-earth metal (Tb, Dy)Fe2 aimed at increasing the transmission level and the reduction of the sound source size. A sound-pressure level above 190 dB (re: 1 μPa at 1 m) with a frequency bandwidth of over 50 Hz were obtained in the depth range between 800 and 1200 m. Field tests for the long-range propagation of several hundreds of kilometers were carried out near the Japan Trench in November 1993. The sound source was moored at a depth of 1242 m and the hydrophone array was moored at a depth of 1385 m. The distance between the sound source and the hydrophone array was 621 km. Received data were recorded with a sufficient signal-to-noise ratio after achieving beamforming to discriminate the sound waves incident upon the hydrophone array from the upper and lower direction. The signals were also received by the acoustic monitoring system suspended from the ship at the distance of 772 km from the sound source. From these results, it is confirmed that this sound source has the capability of 1000-km propagation necessary for the tomography transceiver systems.
1238 Development of Electric Wheel Chair with Active Seat for Level Holding (2005)

It is often difficult for handicapped people using the electric wheelchairs to maintain their posture against external forces. Therefore, it is important to reduce the instability in driving the wheelchair under the various road conditions. In this study, the active level holding seat mechanism available for the general electric wheelchairs is proposed. In order to reduce the increase of seat height, optimal link parameters were designed to minimize the size of linkage. A prototype model of level holding mechanism was made practically. The effect of the proposed mechanism was evaluated by the running tests with electric wheelchair. As the results, the stability of the driver and wheelchair system increase by the decrease of the upper trunk displacement of driver using this seat mechanism.
Temperature-Dependence of the Electrical Resistivity of bcc Cr–Fe Alloys (1960)

The electrical resistivity vs temperature was determined for a bcc Cr+20 at.% Fe alloy from 4.2° to 300°K. The absence of any discontinuity in this curve indicates that the very high temperature-coefficient of the linear term of the specific heat previously found at that composition is not associated with a phase transformation between room temperature and 4.2°K. For bcc Cr-alloys with Fe contents increasing from 0 to 16 at.% Fe the resistivity vs temperature anomaly shifts from approximately 308°K to progressively lower temperatures, and the anomalous resistivity increase with decreasing temperature becomes progressively larger. It is quite possible that these anomalies are connected with antiferromagnetic-paramagnetic transition in the alloys considered.
Digital techniques in load cell weighing (1969)

Typical load cell characteristics are listed and some factors concerning loading are given. An all-electronic system for digitizing the output of load cells directly is described, and details are given of some basic systems used to obtain control and information facilities from the digital weight-signals, with some fundamentals of the binary arithmetic used. Some weighing applications are mentioned and a computer-controlled weighing system is briefly described.
Full-Coverage Film Cooling With Short Normal Injection Holes (2001)

An experimental and computational investigation was conducted on the film cooling adiabatic effectiveness of a flat plate with full coverage film cooling. The full coverage film cooling array was comprised of ten rows of coolant holes, arranged in a staggered pattern, with short L/D=1, normal coolant holes. A single row of cooland holes was also examined to determine the accuracy of a superposition prediction of the full coverage adiabatic effectiveness performance. Large density coolant jets and high mainstream turbulence conditions were utilized to simulate realistic engine conditions. High-resolution adiabatic effectiveness measurements were obtained using infrared imaging techniques and a large-scale flat plate model. Optimum adiabatic effectiveness was found to occur for a blowing ratio of M=0.65. At this blowing ratio separation of the coolant jet immediately downstream of the hole was observed. For M=0.65, the high mainstream turbulence decreased the spatially averaged effectiveness level by 12 percent. The high mainstream turbulence produced a larger effect for lower blowing ratios. The superposition model based on single row effectiveness results over-predicted the full coverage effectiveness levels.

[Long-term selegiline tolerance in the treatment of Parkinson's disease]. (1992)

Tolerability is one of the main problems of the long-term use of antiparkinsonian drugs, especially in the advanced stages of Parkinson's disease. Since 1988, we have performed a prospective study to assess the clinical and therapeutic factors which may influence the tolerability of a new antiparkinsonian drug, selegiline. 168 patients, with a mean age of 68, were treated with selegiline in combination with L-Dopa or with L-Dopa and a dopamine agonist (bromocriptine, lisuride or piribedil). After an average of 19 months, 23 adverse effects (13.7%) were noted during the first three months of treatment with selegiline. Discontinuation was required in only 10 cases (5.9%) with 9 out of 10 for a psychotic episode. Neither age, nor the stage of the disease, nor the dose of levodopa in combination with selegiline or the presence of mental disturbances seemed to be predicting factors for appearance of a psychic episode. If selegiline with levodopa or with bromocriptine and levodopa appeared to be safe antiparkinsonian combinations, significant psychic side effects occurred with piribedil in combinations with selegiline and levodopa. A possible explanation was that selegiline potentiates piribedil side-effects.
The Natural History of Idiopathic Hypoglycemia of Infancy and Its Relation to Diabetes Mellitus (1966)

A SPECIFIC etiology has not been determined in the majority of infants and children with symptomatic spontaneous hypoglycemia.1 This idiopathic hypoglycemia typically has its onset before two years of age, presenting as a seizure disorder. Known endocrine or enzymatic abnormalities cannot be demonstrated, and there are no characteristic physical signs. The hypoglycemia may be continuous or intermittent, can vary greatly in severity from time to time and under-goes spontaneous amelioration over a period of months or years.The present study was undertaken to define a 2ssible relation between infantile idiopathic spontaneous hypoglycemia and other familial abnormalities in carbohydrate metabolism.

Enhanced absorption of light due to multiple surface-plasmon-polariton waves (2011)

Rigorous coupled-wave analysis was used to compute the absorptance of a metallic surface-relief grating coated with a semiconductor layer. The grating is formed by periodic bumps on an otherwise planar layer of a suitable metal. When the period of the surface-relief grating is appropriate, at a certain incidence angle the incident light excites a p-polarized surface-plasmon-polariton (SPP) wave if the semiconductor layer is homogeneous. However, if the semiconductor layer is periodically non-homogeneous normal to the mean metal/semiconductor interface, more than one SPP waves with different polarization states, phase speeds, and attenuation rates can be excited. The use of a periodically nonhomogeneous semiconductor layer for excitation of multiple SPP waves with different polarization states, phase speeds, and attenuation rates can help enhance light absorption in thin-film solar cells.

PHASE CHANGES IN METAL SURFACES DURING EROSION BY SPARK OR OTHER HIGH- ENERGY TREATMENT. (1971)

L3T4 is a mouse cell surface protein expressed on most thymocytes and on the subset of mature T cells that recognizes class II MHC molecules. Its primary function on T cells is most likely that of increasing the avidity of the interaction between T cells and antigen-presenting or target cells. It may accomplish this by binding to a nonpolymorphic region on class II MHC molecules. The cDNA and gene encoding L3T4 have been isolated and sequenced. Analysis of the amino acid sequence predicted by the nucleotide sequence indicates that L3T4 is a member of the Ig gene superfamily. It is most closely related to Ig and Tcr V regions. Although the amino-terminal domain of L3T4 is the portion of the molecule that is most similar to V-regions, L3T4 is one of the polydomain members of the Ig gene superfamily. Studies of the expression of L3T4 mRNA in various tissues led to the surprising finding that this gene is transcribed not only in T lymphoid cells, but also in brain. The predominant form of L3T4 mRNA expressed in brain is foreshortened as compared to that in T lineage cells, and it is most likely the product of a distinct transcriptional start site. If translated, the protein encoded by this brain transcript would be 217 amino acids in length and would lack the signal peptide and the amino-terminal 214 amino acids of the mature protein. It is not known whether a stable protein product is synthesized from this mRNA or what its function might be. However, these findings place L3T4 in an intriguing class of Ig gene superfamily members characterized by coexpression in the immune system and the nervous system.
Isolation of recessive developmental mutants in Coprinus cinereus. (1986)

The basidiomycete Coprinus cinereus (Fr.) Gray has several characteristics which make it suitable for developmental studies (1, 2). The development of normal dikaryotic fruit bodies can be divided into three successive steps: the formation of aggregated hyphal knots of mycelial cells, the formation of fruit body primordia, and the maturation of primordia into mature fruit bodies. A number of developmental mutants of C. cinereus were isolated from dikaryons by TAKEMARU and KAMADA, and it has been found that these mutations are dominant to the normal alleles (3). C. cinereus can normally form a fruit body after the mating between two heterothallic strains. Mutants of the incompatibility factors A and B (Amut and Bmut) have been isolated (4). The Amut Bmut strain has several features characteristic of the dikaryon including the production of mature fruit bodies, but they retain a few features typically associated with monokaryons, such as production of abundant oidia (4). By using the monokaryotic Amut Bmut oidia, which develop homokaryotic fruit bodies, we were able to isolate the recessive developmental mutants. The present communication describes the isolation of four types of recessive developmental mutants from the Amut Bmut strain.
Exception Handling in Electronic Contracting (2009)

In a contract, exceptional clauses specify sanctions that come in force when the primary obligations are not fulfilled. An important aspect of exception handling is their resolution: determining which particular exception clause should be enforced when a violation is detected. This paper presents a specification and resolution technique for electronic contracts that can be used by a third party exception resolution service.
Alkenes from β-lithiooxyphosphonium ylides generated by trapping α-lithiated terminal epoxides with triphenylphosphine (2012)

Terminal epoxides undergo lithium 2,2,6,6-tetramethylpiperidide-induced α-lithiation and subsequent interception with Ph(3)P to provide a new and direct entry to β-lithiooxyphosphonium ylides. The intermediacy of such an ylide is demonstrated by representative alkene-forming reactions with chloromethyl pivalate, benzaldehyde and CD(3)OD, giving a Z-allylic pivalate, a conjugated E-allylic alcohol and a partially deuterated terminal alkene, respectively, in modest yields.
Toward the Coexistence of 5G MmWave Networks with Incumbent Systems beyond 70 GHz (2018)

Cellular networks are on the verge of enabling mobile millimeter-wave access beyond the traditional sub-6 GHz spectrum. Indeed, standardization of 5G-NR has already started, with an eye on enabling gigabit connectivity over 28 GHz and 39 GHz bands. Nevertheless, there remains a plethora of spectrum beyond these bands, and specifically at 70 GHz (71-76 GHz) and 80 GHz (81-86 GHz). A key issue in the aforementioned bands is the presence of licensed incumbent systems that provide point-to-point services. This article provides an overview of recent efforts toward the coexistence of 5G systems with these incumbents. Specifically, we analyze the 5G interference into incumbent receivers and present practical active and passive interference management techniques. We validate the 5G coexistence with detailed network simulations and show the feasibility of 5G connectivity beyond 70 GHz using an experimental prototype. Finally, we highlight future research venues for 5G coexistence with incumbent systems.
Pitfalls and problems in studies on the methylation of phosphatidylethanolamine. (1983)

Recent articles have confused the steady state concentration of radioactivity in N-methylphosphatidylethanolamine (PME) and N,N-dimethylphosphatidylethanolamine (PDE) with the amount of these products formed during the conversion of phosphatidylethanolamine (PE) to phosphatidylcholine (PC). This paper clarifies this problem and reports the apparent Km values for AdoMet and pH optima for the conversion of PE to PME, PDE, and PC by rat liver microsomes. We purified AdoMet and [methyl-3H]AdoMet and measured the transfer of tritium to PME, PDE, and PC as a function of time. There was an initial lag in the formation of [3H]PC followed by linear incorporation of isotope. In contrast, labeled PME and PDE reached and maintained steady state levels within 1 to 2 min. Hence, calculations of the rate of formation of PME, PDE, and PC must take into account the subsequent conversion of PME and PDE to PC. The PE N-methyltransferase was assayed at pH 6.6, 9.2, and 10.25 and the apparent Km for AdoMet for the three methylation reactions was calculated. The formation of PME was best estimated by the dpm in PME + 1/2 dpm in PDE + 1/3 dpm in PC. The synthesis of PDE from PME was estimated from 1/2 dpm in PDE and 1/3 dpm in PC, and the formation of PC from PDE estimated by 1/3 dpm in PC. The apparent Km for AdoMet at pH 10.25 for the conversion of PE to PME was 58 microM, PME to PDE was 65 microM, and PDE to PC was 96 microM. The pH optimum for each of these methylation reactions was 10.25. This high value was not due to alkaline degradation of AdoMet or denaturation of the enzyme. The apparent Km for AdoMet was also estimated for the conversion of exogenous PME to PDE (50 microM) and exogenous PDE to PC (45 microM). Since recent studies on the methylation of PE have not taken into account the conversion of newly formed PME and PDE to PC, the results and conclusions about apparent Km values for AdoMet, pH optima, and the number of enzymes involved must be re-evaluated.

THE RETINA HOTLINE (2010)

A service such as the Retina Hotline seems necessary and well justified against the background of need for information and support documented. However, on the basis of an adequate computer program and a standard catalog of answers or flow charts, it may not need to be staffed by ophthalmologists, but well-trained nonmedical staff may be sufficient.
Application of Frequency-Domain Thermal Measurements in Electronics Packaging (2009)

Increase of power densities has become the primary constraint for semiconductor industry to sustain the Moore’s law for microprocessor evolution. Further development of packaging technology and advanced thermal interface materials (TIMs) requires both maximization of the total thermal throughput of the system and mitigation of the thermal impact from non-uniformly distributed hotspots. Therefore, thermal characterization techniques capable of resolving partial thermal resistances at the component level have received increased emphasis in development of advanced packaging technologies. This work develops a practical method for thermal characterization of IC packages using the frequency-domain measurement technique. It is well suited for investigation of package thermal performance during various application-specific tests in field conditions, as well as a tool for development of TIM and optimization of packaging process. Both steady-state and dynamic thermal characterizations of the IC packages can be achieved using this technique. Various applications, such as thermal structure function measurement, silicon die hot-spot detection, and in-situ thermal/mechanical characterization of TIMs are discussed.
Natural Bond Orbital Analysis of Carbon-13 Chemical Shieldings in Acetylenes (1996)

Ab initio calculations of NMR chemical shieldings of alkyne carbon atoms in nine acetylene compounds computed by the gauge-including atomic orbital (GIAO) method are reported. The unusually low chemical shielding anisotropy (159 ppm) found in the terminal alkyne carbon of phenylacetylene is found to be due to the Ramsey diamagnetic component of the shielding tensor rather than the paramagnetic component, which is commonly associated with large changes in shielding. Natural bond orbital analysis of ab initio molecular orbital wave functions has been used to provide insight into the role of electronic delocalization in the chemical shielding.
Precursor of cdk5 activator, the 23 kDa subunit of tau protein kinase II: Its sequence and developmental change in brain (1994)

Tau protein kinase II (TPKII) is shown by immunoprecipitation to be a complex composed of two subunits, a catalytic subunit, cdk5, and regulatory subunit, p23. By sequence analysis of p23 cDNA, p23 was found to occupy a region from the 99th amino acid residue to the C-terminus of a novel protein with a molecular weight of 34,000 Da, suggesting that this 34 kDa protein is a precursor of p23 (pre-p23). These findings suggest that p23 results from the processing of the precursor protein, pre-p23. The precursor mRNA was expressed most abundantly in rat brain just before and after birth. Expression of pre-p23, but not of cdk5, mRNA changed, coinciding with the developmental change of TPKII activity, suggesting that its expression controls the phosphorylation of tau by the TPKII/TPKI system in the neonatal brain. p23 appears to be a cdk5 activator in neuronal cells.
Rehabilitation after Anterior Cruciate Ligament Reconstruction: A Prospective, Randomized, Double-Blind Comparison of Programs Administered over 2 Different Time Intervals (2005)

Anterior cruciate ligament reconstruction with a bone-patellar tendon-bone graft followed by either accelerated or nonaccelerated rehabilitation produces the same increase of anterior knee laxity. Both programs had the same effect in terms of clinical assessment, patient satisfaction, functional performance, and the biomarkers of articular cartilage metabolism. There is concern that the cartilage biomarkers remained elevated for an extended period.
Creating multi-touch haptic feedback on an electrostatic tactile display (2018)

Electro vibration is a promising method used to generate tactile feedback on touch screens. Although the method has recently received considerable attention from tactile display developers, almost all efforts so far have focused on single touch applications. However, extending this technology to apply to multi-touch systems is required to benefit from the rapidly growing touch screen industry. Through the course of this study, we propose a method and present a tactile display prototype that creates multi-touch tactile feedback using electrostatic attraction. The method relies on applying high-voltage AC signals on certain orthogonal electrode lines resulting in perceivable changes of friction at the intersection points. Generated surface friction on the prototype is measured using a planar tribometer. Results reveal that multiple localized friction spots can be generated with the proposed method. A user study is also carried out to test the prototype in a multi-touch scenario where two fingers explore a virtual texture simultaneously. Additionally, quantitative and qualitative analyses demonstrate the feasibility of creating multi-touch haptic feedback on an electrostatic tactile display.
