An enhanced channel-quality indication (CQI) reporting scheme for HSDPA systems (2005)

A major evolution of UMTS standard is the high speed downlink packet access (HSDPA). One of key techniques supporting HSDPA is the adaptive modulation and coding (AMC) in which the modulation scheme and the coding rate are adaptively changed according to the downlink channel quality reported by the user equipment (UE). Therefore, the channel quality indication (CQI) reporting scheme is directly related to the accuracy of AMC and the performance of HSDPA. This letter proposes an enhanced CQI reporting scheme that can be used when a proportional fair scheduling algorithm (PFA) is used as a packet scheduling algorithm. The proposed scheme uses a dynamic threshold to filter off redundant CQI reports. With the proposed scheme, the battery capacity of UK can be conserved, maintaining the performance of traditional CQI reporting scheme.
A synthetic HIV-1 Rev inhibitor interfering with the CRM1-mediated nuclear export (2002)

The HIV-1 Rev protein is an essential regulator of the HIV-1 mRNA expression that promotes the export of unspliced and partially spliced mRNA. The export receptor for the leucine-rich nuclear export signal (NES) of Rev has recently been recognized as CRM1. We identified a low molecular weight compound PKF050-638 as an inhibitor of HIV-1 Rev. This drug inhibits in a dose-dependent fashion Rev-dependent mRNA expression in a cellular assay for Rev function. We show that PKF050-638 is an inhibitor of the CRM1-mediated Rev nuclear export. By using a quantitative in vitro CRM1-NES cargo-binding assay, we could demonstrate that PKF050-638 disrupts CRM1-NES interaction. This mode of action is confirmed in cell culture because the drug reversibly interferes with the colocalization of CRM1 and Rev in the nucleolus of the cell. In addition, we prove that the inhibition is through direct interaction of the compound with Cys-539 of CRM1. These effects are similar to those of the known CRM1 inhibitor leptomycin B and suggest that the inhibitory effect of the compound is caused by binding to CRM1 at a similar site. The compound displayed strict structural requirements for its activity, as its enantiomer was inactive in all assays tested. These results show that we identified a drug that interferes with the CRM1-mediated nuclear export of Rev through inhibition of the CRM1-NES complex formation. The reversibility of its binding to CRM1 and its availability through chemical synthesis could make it useful for studying CRM1-mediated export pathways.
Non-d0Mn-driven ferroelectricity in antiferromagneticBaMnO3 (2009)

Using first-principles density-functional theory we predict a ferroelectric ground state---driven by the off-centering of the magnetic ${\text{Mn}}^{4+}$ ion---in perovskite-structure ${\text{BaMnO}}_{3}$. Our finding is surprising since the competition between energy-lowering covalent bond formation and energy-raising Coulombic repulsions usually only favors off-centering on the perovskite $B$ site for nonmagnetic ${d}^{0}$ ions. We explain this tendency for ferroelectric off-centering by analyzing the changes in electronic structure between the centrosymmetric and polar states and by calculating the Born effective charges; we find anomalously large values for Mn and O consistent with our calculated polarization of $12.8\text{ }\ensuremath{\mu}\text{C}/{\text{cm}}^{2}$. Finally, we suggest possible routes by which the perovskite phase may be stabilized over the usual hexagonal phase to enable a practical realization of a single-phase multiferroic.
A gene expression assay for simultaneous measurement of microsatellite instability and anti-tumor immune activity (2019)

Development of a gene expression signature of MSI status raises the possibility of a combined diagnostic assay on a single platform which measures both tumor antigenicity and presence of a suppressed adaptive immune response. Such an assay would have significant advantages over multi-platform assays for both ease of use and turnaround time and could lead to a diagnostic test with improved clinical performance.
Minimally Invasive Sacroiliac Arthrodesis (2008)

Study Design Prospective cohort. Objective Comparing efficacy and outcomes of a new technique for sacroiliac arthrodesis. Background The sacroiliac joint has been described as a possible source of chronic low back pain. However, surgical treatment of sacroiliac pain and dysfunction is controversial. Arthrodesis is normally reserved as a salvage procedure when all others have failed to relieve pain and involves an extensive surgical exposure. We have developed a novel technique of sacroiliac arthrodesis using percutaneously inserted fusion cages filled with bone morphogenic protein. This study describes the radiographic and clinical outcomes of this procedure. Methods Thirteen consecutive patients underwent minimally invasive sacroiliac arthrodesis between February and December 2004 at a single teaching hospital and were prospectively followed. Six patients had bilateral fusions for a total of 19 joints. The average age was 53.1 (range 45 to 62). Average body mass index was 31.2 (range 21.9 to 46.9). Mean follow-up was 29.5 months (range 24 to 35). Diagnosis was confirmed using fluoroscopically guided intra-articular injections of local anesthetic and corticosteroid when their pain was relieved 2 or more hours. Arthrodesis was only performed on patients with positive injections who subsequently had their symptoms recur. Outcome measurements included radiographic assessment for fusion and improvement in visual analog pain scale for low back pain, leg pain, and dyspareunia. Computed tomography scan to evaluate implant placement was performed postoperatively and again at 6 months to assess fusion. Results The overall fusion rate was 89% (17/19 joints). Significant improvements were seen in final low back pain score on a visual analog scale (0 to 10) (average improvement 4.9, P≤0.001). Leg pain improved an average of 2.4 (P=0.013). Dyspareunia improved an average of 2.6 (P=0.0028). One patient was revised to an open arthrodesis secondary to nonunion and persistent pain. There were no infections or neurovascular complications. Conclusions Minimally invasive sacroiliac arthrodesis via a percutaneous posterior approach is a safe and efficacious procedure, leading to a high fusion rate and significant improvement in low back, leg pain, and dyspareunia.

An analysis of pilot symbol assisted 16 QAM in the Rayleigh fading channel (1995)

The paper proposes the performance of a pilot symbol assisted modulation (PSAM) using Gaussian interpolation and Wiener interpolation method. Although QAM is the most spectrally efficient modulation, it is rarely applied in mobile channels because of multipath fading. A PSAM system estimates and compensates fading. The paper shows the performance of the PSAM in the case of using Gaussian interpolation and Wiener interpolation, respectively. Computer simulation results shows that the performance of Wiener is better than that of Gaussian interpolation.
Side Lobe Reduction Using Centroid and Flatness in Passive Cavitation Imaging (2019)

Cavitation bubbles generated by high-intensity focused ultrasound strongly collapse and emit ultrasound waves. Since passive cavitation imaging can be performed using only receive focusing, side lobes appear over a wide area of an image. The delay and sum beamforming technique used to construct passive cavitation images cannot effectively image the cavitation occurrence time and spatial distribution because a small cavitation signal is buried in the side lobe of a large cavitation signal when there are a large number of cavitation bubbles. The ultrasound wave emitted when the cavitation bubble collapses is a short duration pulse. After compensating for the focusing delay, the signals due to the main lobe (at the imaging point) received at each element of the transducer array are similar in magnitude, but those due to the side lobes (other than the imaging point) is significant only at some elements of the array. Using this characteristic of the received channel data, we propose both centroid and flatness as metrics to evaluate the effect of the main and side lobes at imaging points. If the centroid of the signal magnitude distribution of the entire receiving channel is positioned at the center of the array, the signal is considered to be due to the main lobe. However, if the centroid is computed to be located near both ends of the array, the signal is considered to be due to the side lobes. If the signals are found to be due to the side lobes in passive cavitation imaging, the pixel brightness is reduced by weighting using the centroid and flatness metrics. We computed the centroid and flatness metrics using computer simulation and experimental data, and confirmed the suppression of side lobes by multiplying the image by a weight using the centroid and flatness. The proposed method makes it easier to observe cavitation by effectively removing side lobes from passive cavitation images when the number of cavitation bubbles is not large.

Interferential powders for the spectral control of light scattering (2004)

Optical interference coatings usually offer large possibilities for the spectral control of specular reflected or transmitted light. In this aim, multilayer structures are calculated and realized according to each specific application. These kinds of components are deposited over plane substrates, or on substrates with large curvature radius. In this paper we show how multilayer components can also be deposited on micro spheres to reach other applications connected with the spectral control of light scattering.

Turbomachinery monitoring systems capture and analyze vibration data (1991)

An integrated, computerized monitoring system that provides for the capture and analysis of vibration data is described. The heart of the system is the Transient Data Manager (TDM) Communications Processor (CP), a computer interface that captures data during machine startup or coastdown. In addition, steady-state data are captured during online machine operation. Data captured include current static values and dynamic waveforms. The system collects and stores static data every four seconds from each monitor in a rack. In addition, dynamic transducer waveform data are captured and stored from each applicable monitor approximately every 40 seconds. Any time an alert, danger, or transducer-not-OK status is detected, the information is stored in an alarm event list. A status change notification is sent to the computer, and the computer subsequently retrieves the list and notifies the user of the status change. The system consists of at least one CP, software, and a computer. Examples of its application are provided. The future use of expert systems for this application is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Correlation between Charpy Transition Temperature and Brittle Crack Arrest Temperature Considering Texture (2011)

The correlation between ESSO test results and Charpy impact properties has been empirically proposed to qualify brittle crack arrest toughness, Kca of structural steels. The brittle crack arrest temperature TK6000 at Kca=6000N/mm3/2, conventionally used as a measure of crack arrest property, is interrelated generally with the Charpy transition temperature vTrs. However, ESSO test results occasionally deviates from the TK6000-vTrs correlation in some TMCP steels. Considering a thickness effect in ESSO test results, TK6000 was converted to a reference temperature 25TK6000 for 25mm thickness. Nevertheless, a scatter is found in 25TK6000-vTrs correlation.This study focuses on the effect of texture intensity on crack arrest properties. It is found that steel plates with texture show lower 25TK6000 than other steels without texture, even if the transition temperatures vTrs of these steels are on the same level. The role of the (211) texture is more significant than the (100) texture. A new parameter, vTrs (°C) -12X(100) -22X(211), is proposed in this study to correlate the crack arrest temperature 25TK6000 with the material properties of structural steels, where X(100) : pole density of (100) parallel to surface of steel plate, X(211): pole density of (211) parallel to surface of steel plate.

Ion mass spectroscopy investigations during high power pulsed 1 magnetron sputtering and DCMS of Carbon in an Ar and Ar/N2 discharge (2012)

Alcohol and drug dependence among the elderly is common and yet frequently underdiagnosed. The practice of self-administration of prescribed medications, particularly sedative/hypnotics, benzodiazepines, and nonprescription, over-the-counter (OTC) medications is prevalent, with untoward consequences in the geriatric population. Dementia, depression, and anxiety syndromes are some of the consequences of alcohol and drug dependence, and may mimic other causes of these disorders. The clinician's index of suspicion must be high enough to make the proper diagnosis of these alcohol- and drug-induced syndromes. Unnecessary evaluations, improper diagnosis, and ineffective and costly treatments may be avoided if alcohol and drug dependence is identified and treated. Effective treatment for alcohol and drug dependence does exist for the elderly and may be instituted in a cost-effective manner.
Solution properties of porcine submaxillary mucin (1983)

Abstract Porcine submaxillary mucin (PSM) is a glycoprotein composed of a protein core and frequent, short oligosaccharide side chains. We report static and dynamic light scattering experiments and intrinsic viscosities for PSM in aqueous solvent systems. In 0.1 M NaCl solution, the data suggest PSM exists as large, internally branched, highly hydrated, polydisperse aggregates that slowly dissociate to give a stable species of weight‐average molecular weight ( M w ) 7.4 × 10 6 . In 6 M GdnHCl solution, the noncovalent bonds between PSM molecules are broken, giving a highly elongated molecule of M w = 2.0 × 10 6 . The irreversible nature of this dissociation suggests that the forces that stabilize the native aggregates of PSM in 0.1 M NaCl are specific in nature. On reduction of PSM with mercaptoethanol, the polydispersity decreases and M w also decreases to 9 × 10 5 . A discrete change is observed in the solution properties of PSM in 0.1 M NaCl at a concentration of 2mg/mL, manifested by a sudden decrease in the translational diffusion coefficient, an increase in viscosity number, and a decrease in slope of the osmotic compressibility. We tentatively propose that a weak and reversible secondary association process occurs at this concentration, although a purely hydrodynamic interaction cannot be ruled out.
Prospective evaluation of short-term, high-volume isovolemic hemofiltration on the hemodynamic course and outcome in patients with intractable circulatory failure resulting from septic shock (2000)

GaAs/AlGaAs quantum wells with indirect-gap AlGaAs barriers for solar cell applications (2014)

We have fabricated GaAs/AlGaAs quantum well (QW) solar cells in which 3 nm-thick QWs and indirect-gap Al0.78Ga0.22As barriers are embedded, and we studied extraction processes of photogenerated carriers in this QW system. The photocurrent under 700 nm light illumination at voltages close to the open-circuit voltage shows only a small reduction, indicating that the carrier recombination inside QWs is largely suppressed. We attribute this result to an efficient extraction of electrons from the QWs through the X-valley of AlGaAs. The insertion of QWs is shown to be effective in extending the absorption wavelengths and in enhancing the photocurrent. The use of indirect-gap materials as barriers is found to enhance carrier extraction processes, and result in an improved performance of QW solar cells.

Consolidation and mechanical properties of ZrCu39.85Y2.37Al1.8 bulk metallic glass obtained from gas-atomized powders by spark plasma sintering (2021)

This manuscript proposes subjecting gas-atomized powders of ZrCu39.85Y2.37Al1.8 metallic glass to spark plasma sintering (SPS). This bulk metallic glass (BMG) sinters at a temperature between its crystallization (Tx) and glass transition (Tg) temperatures, found to be 457 °C and 368 °C, respectively, via Differential Scanning Calorimetry (DSC). Several samples were sintered at different temperatures within the mentioned range (380, 390, 400, 415 and 430 °C). Experimental results confirmed successful sintering of the BMG by SPS at 390 °C and a pressure of 35 MPa. Fully amorphous compacts with almost 100% relative density were sintered at this temperature, reaching Young's modulus, Vickers hardness and compression strength values of 64.7 GPa, 396 HV0.3 and 1174 MPa, respectively. Sintering at higher temperatures involved crystallization of the sample. Results suggest that ZrCu39.85Y2.37Al1.8 metallic glass fabricated by SPS is a promising material for applications in different sectors, particularly jewelry, due to the wear resistance conferred by its hardness.
Early Transition Niobium Compounds in Organic Transformation^|^mdash;From Stoichiometric Reaction to Catalytic Reaction (2014)

This review consists mainly of stoichiometric reaction and catalytic reaction using niobium complexes. As an example of stoichiometric reaction, synthesis of 1H-indenes from the reaction of aliphatic ketones and aryl-substituted alkynes in the presence of stoichiometric amount of NbCl3(DME) has been documented. Alternatively, development of catalytic reaction of using low-valent Nb is intriguing. Our research group reported that low-valent Nb catalyzed intermolecular [2+2+2] cycloaddition reaction of alkynes with alkenes leading to tri- or tetra-substituted 1,3-cyclohexadienes in chemo- and regioselectivity. In addition, low-valent Nb catalyzed cycloaddition reaction of tert-butylacetylene with aryl-substituted nitriles to tri-substituted pyridines has been reported.
Formation and Stabilization of Raphasatin and Sulforaphene from Radish Roots by Endogenous Enzymolysis (2015)

The biologically active compounds raphasatin and sulforaphene are formed during the hydrolysis of radishes by an endogenous myrosinase. Raphasatin is very unstable, and it is generated and simultaneously degraded to less active compounds during hydrolysis in aqueous media. This study determined the hydrolysis conditions to maximize the formation of raphasatin and sulforaphene by an endogenous myrosinase and minimize their degradation during the hydrolysis of radish roots. The reaction parameters, such as the reaction medium, reaction time, type of mixing, and reaction temperature were optimized. A stability test for raphasatin and sulforaphene was also performed during storage of the hydrolyzed products at 25°C for 10 days. The formation and breakdown of raphasatin and sulforaphene in radish roots by endogenous enzymolysis was strongly influenced by the reaction medium, reaction time, and type of mixing. The production and stabilization of raphasatin in radishes was efficient in water and dichloromethane with shaking for 15 min at 25°C. For sulforaphene, the favorable condition was water as the reaction medium without shaking for 10 min at 25°C. The maximum yields of raphasatin and sulforaphene were achieved in a concurrent hydrolysis reaction without shaking in water for 10 min and then with shaking in dichloromethane for 15 min at 25°C. Under these conditions, the yields of raphasatin and sulforaphene were maximized at 12.89 and 1.93 μmol/g of dry radish, respectively. The stabilities of raphasatin and sulforaphene in the hydrolyzed products were 56.4% and 86.5% after 10 days of storage in water and dichloromethane at 25°C.
