Attenuation of broadband noise in a reverberant room using a multichannel active noise control system (1995)

Active noise control (ANC) is often discussed in the context of reducing noise in vehicles. The acoustic reverberation of typical vehicle cabins makes the application of ANC to quieting interior noise a stiff challenge. While some ANC approaches take advantage of the modal structure of reverberant enclosures to provide reduction throughout the enclosure, these approaches become infeasible for many frequency bands of practical interest because of increasing modal density with increasing frequency. For high-bandwidth, diffuse fields, noise reduction is achieved locally by specifying a quiet zone within the enclosure. Experimental results for broadband, local quieting in a diffuse field using a multichannel ANC system are presented. The reverberant enclosure is an ordinary room, measuring approximately 1.4 m×2.4 m×2.4 m and containing a seated operator with six microphones defining the quiet zone near the operator’s ears. The control system uses a single reference signal and two error channels to drive four control speakers. An average of 20-dB reduction in sound pressure level is found at the quiet-zone microphones for the frequency range 50 to 1000 Hz. These results demonstrate the viability of real-time, multichannel ANC for locally attenuating random noise in diffuse acoustic fields.
Hospital Surgical Volume Is Poorly Correlated With Delivery of Multimodal Treatment for Localized Pancreatic Cancer (2022)

Although the volume-outcome relationship for pancreatic cancer has demonstrated improved outcomes, this work identified poor correlation between hospital surgical volume and delivery of multimodal treatment. The role of care coordination in the delivery of multimodal treatment warrants further investigation as it is associated with improved survival for patients with localized pancreatic cancer.

New Fiber Configuration for Intravenous Gas Exchange (2005)

Implantation of a membrane oxygenator (IO) into the vena cava for blood oxygenation in patients with acute lung failure has been researched for the last 25 years. Compared to the extra corporeal blood oxygenation, where blood is handled outside the body, IO doesn't present tubes, housings or heat exchangers, thus reducing considerably blood contact surface and setting priming volume to zero. Otherwise, restricted space in the vena cava and unadvantageous blood flow conditions represent so far a limitation for sufficient gas exchange. A new fiber configuration for intravenous use is being developed, which increases the implantable fiber surface and enhances gas exchange due to the increased blood convection. This is made possible by new fiber bundles, which are free to slide on a catheter and after implantation assume a twisted shape characterized by high homogeneity and fiber density.
Coulomb drag and plasmonic effects in graphene field-effect transistors enable resonant terahertz detection (2022)

We analyze the response of lateral n+-i-n-n+ graphene field-effect transistors (GFETs) to terahertz (THz) radiation. The nonlinearity due to the Coulomb drag of quasi-equilibrium carriers by injected ballistic carriers accompanied by plasmonic oscillations in a GFET channel enables a resonantly strong response. This effect can be used for effective resonant detection of THz radiation.
Complexes with FeIII2(μ-O)(μ-OH), FeIII2(μ-O)2, and [FeIII3(μ2-O)3] Cores:  Structures, Spectroscopy, and Core Interconversions (1999)

We have synthesized the first complexes with bis(μ-oxo)diiron(III) and (μ-oxo)(μ-hydroxo)diiron(III) cores (1 and 2, L = TPA (a), 5-Et3-TPA (b), 6-Me3-TPA (c), 4,6-Me6-TPA (d), BQPA (e), BPEEN (f), and BPMEN (g)) and found them to have novel structural properties. In particular, the presence of two single-atom bridges in these complexes constrains the Fe−Fe distances to 2.7−3.0 Å and the Fe−μ-O−Fe angles to 100° or smaller. The significantly acute Fe−O−Fe angles (e.g., 92.5(2)° for 1c and 100.2(2)° for 2f) enforced by the Fe2O2(H) core endow these complexes with UV−vis, Raman, and magnetic properties quite distinct from those of other (μ-oxo)diiron(III) complexes. Complex 1c exhibits visible absorption bands at 470 (ε = 560 M-1 cm-1) and 760 nm (ε = 80 M-1 cm-1), while complexes 2 show features at ca. 550 (ε ≈ 800 M-1 cm-1) and ca. 800 nm (ε ≈ 70 M-1 cm-1), all of which are red shifted compared to those of other (μ-oxo)diiron(III) complexes. These complexes also exhibit distinct νFe-O-Fe vibrations at ca. 600 and ca. 670 cm-1 assigned to the νsym and the νasym of the Fe−O−Fe units, respectively. The relative intensities of the νsym and νasym bands are affected by the symmetry of the Fe−O−Fe units; an unsymmetric core enhances the intensity of the νasym. Complexes 2 exhibit another band at ca. 500 cm-1, which is assigned to the Fe−(OH)−Fe stretching mode due to its sensitivity to both H218O and 2H2O. Magnetic susceptibility studies reveal J = 54 cm-1 for 1c and ca. 110 cm-1 for 2 (H = JS1·S2), values smaller than those for the antiferromagnetic interactions found in (μ-oxo)diiron(III) complexes. This weakening arises from the longer Fe−μ-O bonds and the smaller Fe−μ-O−Fe angles in the Fe2O2(H) diamond core structure. These spectroscopic signatures can thus serve as useful tools to ascertain the presence of such core structures in metalloenzyme active sites. These two core structures, Fe2(μ-O)2 (1) and Fe2(μ-O)(μ-OH) (2), can also be interconverted by protonation equilibria with pKa's of 16−18 in CH3CN. Furthermore, the Fe2(μ-O)2 core (1) isomerizes to the Fe3(μ2-O)3 core (7), while the Fe2(μ-O)(μ-OH) core (2) exhibits aquation equilibria to the Fe2(μ-O)(μ-H3O2) core (5), except for L = 6-Me3-TPA and 4,6-Me6-TPA. It is clear from these studies that electronic and steric properties of the ligands significantly affect the various equilibria, demonstrating a rich chemistry involving water-derived ligands alone.
Throughput Optimisation for Real-time Setup of Cold Mills (1996)

Cold rolling mills are highly automated in today's manufacturing sector. Prior to the strip being rolled in the mill, the rolling stand actuators have to be 'set up' to their correct values. In particular, the gap between the work rolls and the roll speeds have to be precisely determined and set. These settings rely upon models which are complicated in nature and demand considerations of numerous practical constraints. This paper describes recent developments and improvements made to those models to optimise the throughput of the mill during the setup procedure. This includes a model to monitor the thermal condition of the mill motors in order to optimise the motor power utilisation, and a dynamic load redistribution algorithm to maximise throughput.
Oversampled orthogonal and biorthogonal multicarrier modulations with perfect reconstruction (2003)

A new system of multicarrier modulation is described, which takes advantage of the biorthogonality property, to generalize the oversampled OFDM technique into a biorthogonal frequency division multiplex scheme named BFDM/QAM. A discrete-time analysis of this scheme leads to a discrete model of modulated transmultiplexer. Using a polyphase decomposition of this transmultiplexer, and assuming a distortion free channel, we determine the mathematical conditions on the prototype filters, allowing an exact cancellation of intersymbol and interchannel interference, i.e. a perfect reconstruction. Then, computationally efficient realizations of the modulators and demodulators are given. Lastly, some design examples are provided.
Data from Co-targeting Bulk Tumor and CSCs in Clinically Translatable TNBC Patient-Derived Xenografts via Combination Nanotherapy (2023)

&lt;div&gt;Abstract&lt;p&gt;Triple-negative breast cancer (TNBC) accounts disproportionally for the majority of breast cancer–related deaths throughout the world. This is largely attributed to lack of a specific therapy capable of targeting both bulk tumor mass and cancer stem cells (CSC), as well as appropriate animal models to accurately evaluate treatment efficacy for clinical translation. Thus, development of effective and clinically translatable targeted therapies for TNBC is an unmet medical need. We developed a hybrid nanoparticles-based co-delivery platform containing both paclitaxel and verteporfin (PV-NP) to target TNBC patient-derived xenograft (PDX) tumor and CSCs. MRI and IVIS imaging were performed on mice containing PDX tumors to assess tumor vascularity and accumulation of NPs. NF-κB, Wnt, and YAP activities were measured by reporter assays. Mice bearing TNBC PDX tumor were treated with PV-NPs and controls, and tumors progression and CSC subpopulations were analyzed. MRI imaging indicated high vascularization of PDX tumors. IVIS imaging showed accumulation of NPs in PDX tumors. In comparison with control-NPs and free-drug combination, PV-NPs significantly retarded tumor growth of TNBC PDX. PV-NPs simultaneously repressed NF-κB, Wnt, and YAP that have been shown to be crucial for cancer growth, CSC development, and tumorigenesis. In conclusion, NPs containing two clinically used drugs concurrently inhibited NF-κB, Wnt, and YAP pathways and exhibited synergic effects on killing TNBC bulk tumor and CSCs. This combination nanotherapy evaluated with a PDX model may lead to an effective treatment of patients with TNBC.&lt;/p&gt;&lt;/div&gt;
1.1 ¿m-Range Low Resistive VCSELs with Buried Type-II Tunnel Junctions (2006)

We propose 1.1-μm-range VCSELs with buried Type-II tunnel junctions (BTJs). Due to the small electrical resistance of the Type-II tunnel junction, the chip resistance was reduced by half as compared with oxide confined VCSELs. The BTJ-VCSELs were lased up to 120°C.
Photon-number squeezing in the normal-dispersion regime (1999)

We experimentally demonstrate the generation of amplitude-squeezed light in the normal-dispersion regime and measure by direct detection 1.7+/-0.1 dB (33%) and, with correction for linear losses, 2.5+/-0.2 dB (47%) of noise reduction below the shot-noise level. The dependence of the noise behavior on dispersion is investigated both experimentally and theoretically.
Analysis of continuous curved girder-slab bridges (1989)

A static analysis of horizontally curved, continuous multigirder slab type bridge decks has been proposed using finite difference method in conjunction with the method of consistent deformation. The deck is idealized as a curved thin plate supported by flexible supports having both vertical and rotational flexibility. The proposed Levy-type series solution requires generation of linear equilibrium difference equations only along the central radial line of the deck, thus obviating the need of a large computational molecule. The simple repetitive algorithm for this method of analysis is an advantage in computer programming. Key words: bridges (curved), beams (curved), structural analysis, computation, concrete, steels, moments.
Effects of Environmental Controls on the Growth of Wasabi (Eutrema japonica (Miq.) Koidz.) in a Nutrient Solution Cultivation System (2005)

The effects of controlling minimum nocturnal ambient air temperature, day length and culture medium temperature on growth and yield were studied for the purpose of developing a year-round cultivation system for wasabi (Eutrema japonica (Miq.) Koidz.) . When the minimum night temperature was 5°C in winter, the growth of wasabi leaf was slow but recovered when the temperature rose to 8°C. Extension of day length by supplemental lighting was found to enhance growth recovery. Wasabi was planted at different times of the year to compare the effects of seasonal variation on stem growth. The mean daily growth medium temperature was maintained at 13.5-28.1°C throughout the year. These results revealed little difference in growth and stem pungency due to the season of planting, and stems grew to about 60 g within two years of cultivation. Year-round, stable nutrient solution cultivation of wasabi under environmental control may be an economically feasible alternative to conventional, labor-intensive cultivation systems.
Enzymatic Formation of Cardiolipin from Phosphatidylglycerol by the Transphosphatidylation Mechanism Catalyzed by Phospholipase D (1973)

The enzymatic formation of cardiolipin- 3 H from purified phosphatidylglycerol-2′- 3 H catalyzed by phospholipase D is described. Some general conditions for this formation are studied and discussed. The formation of cardiolipin is independent of cytidine coenzymes and takes place by a transphosphatidylation reaction mechanism in which phosphatidylglycerol serves as the acceptor and as the donor of the phosphatidyl group.
THERAPEUTIC OPTIONS FOR PATIENTS WHO ARE NOT ELIGIBLE FOR INTENSIVE CHEMOTHERAPY (2013)

Although "less intense" therapies are finding more use in AML, the principal problem in AML remains lack of efficacy rather than toxicity. Hence less intense therapies are of little use if they are not more effective as well as less toxic than standard therapies. Assignment of patients to less intense therapies should be based on other factors in addition to age. Azacitidine and decitabine, the most commonly used less intense therapies in AML very probably produce better OS than best "supportive care" or "low-dose" ara-C. However improvement is relatively small when compared to expected life expectancy in the absence of disease. Accordingly, while azacitidine or decitabine should be considered the standards against which newer therapies are compared, continued investigation of potentially more effective therapies needs to continue. Better means for evaluating the large number of these therapies (and their combinations) are also needed.
Tunable RF SAW/BAW filters: Dream or reality? (2011)

This paper discusses possibilities of tunable radio frequency (RF) surface and bulk acoustic wave (SAW/BAW) filters. First, configuration of RF front-end in current wireless communication systems is surveyed, and research trends of the flexible RF front-end and software defined radio (SDR) are discussed. Second, various RF tunable filters are introduced, and we discuss how high performances are expected by the use of tunable RF SAW/BAW filters provided that above mentioned key technologies are developed. Finally, we explain what kinds of research subjects are going on in our projects for realization of the flexible RF front-end for the SDR.

The nitrogen-doped three dimensional graphene aerogels can control uniform deposition of discharge products at the nanoscale for high-performance rechargeable Na–O<sub>2</sub> batteries.
Natural killer T cell strategies to combat Epstein–Barr virus infection (2014)

Epstein-Barr virus (EBV) infection results in rapid loss of CD1d expression from the surface of infected B cells, thus enabling the virus to evade immune recognition by natural killer T (NKT) cells. Using pharmacologic means to boost CD1d expression, potent NKT cell effector functions can be elicited toward EBV-infected B cells, suggesting the promise of novel strategies to target EBV-associated diseases such as some B-cell malignancies.
Multiprimary color display for liquid crystal display projectors using diffraction grating (1999)

To reproduce the natural color of an object through color im- aging systems, the range of the reproducible color, i.e., the color gamut, of the color display devices must be expanded, because the color gamut of current display devices such as cathode ray tubes (CRTs) and liquid crystal displays (LCDs) is insufficient. We present a new method to en- large the color gamut for the LCD device using more than three prima- ries, i.e., multiprimaries, generated by a diffraction grating and a liquid crystal panel. The optical system for the multiprimary color display is introduced, and its capability of increasing the gamut is discussed. The experimental result displayed by seven primary colors is also demon- strated. © 1999 Society of Photo-Optical Instrumentation Engineers. (S0091-3286(99)02011-5)
On the Reaction between Anthracene and the Nitrosonium Ion. A Simple Method for the Preparation of 9,10-Anthraquinone and Some Comments on its Formation in Aromatic Nitration. (1991)

A summary of the possible electron-transfer reactions between anthracene and the nitrosonium ion, and a convenient and simple method for the synthesis of 9,10-anthraquinone from anthracene, NaNO 2 and CH 3 OH in CH 2 Cl 2 /CF 3 COOH are presented. The suggestion that the formation of 9,10-anthraquinone in the N 2 O 4 nitration of anthracene originates from trapping of the anthracene radical cation by water is demonstrated to be invalid, e.g., by experiments involving H 2 18 O. Instead, 9,10-anthraquinone is suggested to be formed in the N 2 O 4 -based and in other related systems via follow-up reactions to an initial 1,4-addition across the 9,10 positions of anthracene
