Ultrasonic Measurement of Orthotropic Elastic Constants of Bovine Femoral Bone (1981)

Using a pulse transmission ultrasound method, we have determined the elastic properties of bone samples taken from along the length and around the periphery of a bovine femur. Twenty specimens, in the form of 5-mm cubes, were tested. All nine of the orthotropic elastic constants were determined for each specimen. Analysis of our data indicate that there are statistically significant variations from the usual assumption of transverse isotropy.
Microgravity and Macromolecular Crystallography (2000)

Macromolecular crystal growth is seen as an ideal experiment to make use of the reduced acceleration environment provided by an orbiting spacecraft. The experiments are small, are simply operated, and have a high potential scientific and economic impact. In this review we examine the theoretical reasons why microgravity is a beneficial environment for crystal growth and survey the history of experiments on the Space Shuttle Orbiter, on unmanned spacecraft, and on the Mir space station. The results of microgravity crystal growth are considerable when one realizes that the comparisons are always between few microgravity-based experiments and a large number of earth-based experiments. Finally, we outline the direction for optimizing the future use of orbiting platforms.
Energy-aware media transcoding in wireless systems (2004)

In distributed systems, transcoding techniques have been used to customize multimedia objects, utilizing trade-offs between the quality and sizes of these objects to provide differentiated services to clients. Our research uses transcoding techniques in wireless systems to customize video streams to the requirements of users, while minimizing the energy costs. We introduce an approach to dynamically determine which transcoders to execute and where to execute them (e.g., client or server). The goal is to select appropriate transcoders (a) to provide clients with the quality of service they desire while (b) minimizing the energy consumption of the end-hosts in accordance with application-specific global energy management directives. This paper investigates sample transcoder functions for video streaming on handheld devices and introduces a mechanism for selecting the most appropriate transcoders and transcoder parameters.
A Compact 6.5-W PHEMT MMIC Power Amplifier for Ku-Band Applications (2007)

A compact 6.5-W AlGaAs/InGaAs/GaAs PHEMT monolithic microwave integrated circuit (MMIC) power amplifier (PA) for Ku-band applications is proposed. This two-stage amplifier with chip size of 8.554mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 </sup> (3.64mmtimes2.35mm) is designed to fully match 50-Omega input and output impedance. Under 8V and 2000mA dc bias condition, the PA deliver 38.1dBm (6.5W) saturated output power, 10.5-dB small signal gain and peak power added efficiency of 24.6% from 13.6 to 14.2GHz. This MMIC also achieved the best power densities (760mW/mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) at Ku band reported to date
SiP Tuner With Integrated LC Tracking Filter for Both Cable and Terrestrial TV Reception (2007)

A silicon tuner has been designed for the reception of analog or digital TV signals from a cable or a terrestrial network. It exhibits 5 dB NF over the 42-870 MHz frequency range and integrates a self-calibrated LC tracking filter. This allows 55 dB video SNR under fully loaded spectrum conditions. The (N + 1) image channel is rejected by more than 62 dB thanks to a fully integrated full complex mixer with auto calibration.

Evaluation of microvascular density in tumors: pro and contra. (2008)

Microvascular density (MVD) counting protocols have become the morphological gold standard to assess the neovasculature in human tumors. This method requires the use of specific markers to vascular endothelium and of immunohistochemical procedures to visualize microvessels. MVD determined in primary tumors is significantly associated with metastasis and prognosis in several tumors and is most predictive in those tumors that induce significant angiogenesis, namely carcinomas of breast and prostate, and haematological malignancies. There is such a wide range of antibodies and suppliers, antigen retrieval methods, designation of high and low vessel count groups, patient study groups and data interpretation, that it is exceedingly difficult to compare results.

Physiological and Pathological Factors Influencing Bovine Serum Albumin Content of Milk (1983)

Concentrations of albumin from bovine blood serum were measured by radial immunodiffusion of 480 milk samples. Content in milk was not affected by content in serum, lactation number, or location of quarters. Bovine serum albumin concentrations in milk increased at the end of lactation (270 days) compared to the beginning (30 days) and at midlactation (150 days). Uninfected quarters had a mean concentration of serum albumin of .193 mg/ml. This was less than means for quarters infected by minor pathogens (.242 mg/ml) and by major pathogens (.284 mg/ml). Distributions of concentrations related to infection status, however, overlapped substantially. Somatic cell count was correlated .53 with concentrations of blood serum albumin in milk. About 32% of quarters infected by major pathogens had fewer than 500 x 10(3) cells/ml, whereas 47.5% of them had serum albumin content less than .2 mg/ml. For subclinical infections, concentration of serum albumin markedly increased when somatic cells were more than 1,000 x 10(3) cells/ml.
Changes induced by venous occlusion on coagulation and fibrinolysis. (1987)

The present study aimed to evaluate the blood coagulability and fibrinolytic activity in thrombotic patients during the venous occlusion test. Subjects were 7 healthy adults and 16 patients with myocardial infarction, 2 patients with cerebral infarction. Measured were ATIII, PLG, α2PI, P-C, TPA, VIIIC, VIIIRAG, FPA, FPBβ15-42. Before occlusion, mean levels of VIIIRAG in the venous blood were higher and those of P-C were lower in patient group than in control group. After 10 minutes' occlusion, there was no significant difference noted in increase rate of VIIIRAG and TPA between patient and control groups.In conclusion, Venous stasis induces the release of TPA and VIIIRAG without significant difference in increase rate of these substances between patient and control groups. However, the lower level of P-C and higher level of VIIIRAG observed in thrombotic patients indicated that patient group was in hypercoagulable state.

Self-aligned GaAs MISFET's with a low-temperature-grown GaAs gate insulator (1995)

GaAs MISFET's with a low-temperature-grown (LTG) GaAs gate insulator and ion-implanted self-aligned source and drain n/sup +/ regions are demonstrated. The resistivity and breakdown field of the LTG GaAs insulator were not changed appreciably by implantation and 800/spl deg/C activation annealing. The gate leakage current remained very low at a value of approximately 1 μA per μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of gate area at 3 V forward gate bias. Because of the reduced source and drain resistance, the drain saturation current and the transconductance of self-aligned MISFET's increased more than twofold after ion implantation.
The chemical composition of water trees in EPR cable insulation (1994)

The earlier observation of carboxylate ions in vented water trees in service-aged XLPE cable insulation is extended to bow-tie trees in lab-aged XLPE cable insulation, and to bow-tie and vented trees in EPR cable and slab specimens. Carboxylate anions were the major carbonyl-containing functionality in the treed regions, except for cases where ester functionalities (from antioxidants or shield materials) or aromatic carbonyl species (curative residues) had accumulated. Ketonic oxidation products were detected, but at a lower level than carboxylates. The experimental difficulty of detecting carboxylate ions in the presence of interfering absorptions from methylene blue dye and clay filler was circumvented by the use of a derivatization technique involving sulfur tetrafluoride and with hydrogen chloride, which converted carboxylate ions to acid fluorides and carboxylic acids respectively. Some examples of initiation sites for water tree formation in EPR are provided. When a particulate initiation site of bow-tie trees in EPR could be identified, a common feature was the presence of transition metal ions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tremor Detection Using Motion Filtering and SVM (2013)

The hand tremor is one of the most common motion disorders caused by various neurological diseases. Currently diagnostic procedures for tremor evaluation are subjective, and there are no examinations available that can accurately indicate whether tremors are present in a patient’s daily life. Early detection of tremor is extremely important for the cure of the disease that causes the tremor. Thus, in this study we aim to develop a computational method based on machine learning that can automatically detect hand tremors from a video of a patient when the patient is doing his/her daily activities. The main challenge in tremor detection is that motion is very subtle, and the signature of the motion can vary from patient to patient. We first generate a training data set consisting of 173 simulated tremor/non-tremor video files. They contain very subtle and less discriminative motions. The main contributions of our study are the personalized skin detection, motion filtering and feature extraction pipeline. We evaluated our method through leave-one-out cross validation (LOOCV) testing and showed that in preliminary tests our method achieved 95.4 % recognition accuracy. 1 1.
Mechanical properties of styrene–butadiene–styrene block copolymer composites filled with calcium carbonate treated by liquid polybutadienes (2009)

Abstract The factors influencing the mechanical properties of styrene–butadiene–styrene block copolymer (SBS) composites filled with liquid polybutadiene (LB)‐surface‐treated calcium carbonate (CaCO 3 ) were investigated with respect to the molecular structure of the LB, the amount of the LB adsorbed on the CaCO 3 surface, the heat treatment conditions, and the surface treatment method. The mechanical properties, such as the modulus, tensile strength at break, tear strength, storage modulus, and tension set, of the SBS composites were improved remarkably through the filling of CaCO 3 surface‐treated with a carboxylated LB with a high content of 1,2‐double bonds. The heat treatment of LB–CaCO 3 in air was also effective in enhancing such properties. When SBS, CaCO 3 , and LB were directly blended (with the integral blend method), secondary aggregation of CaCO 3 took place, and the mechanical properties of the composite were significantly lower. In the integral blend method, LB functioned as a plasticizer. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Intelligent recommendation system for customized ergonomic furniture design (2017)

Manufacturers producing ready-to-assembly furniture are experiencing an increasing demand from customers, who expect products to be customised so as to fit their particular needs. To this purpose, in this paper we propose a system for the design of customized ergonomic furniture using anthropometric dimensions. The proposed system is based on the extraction of basic anthropometric measurements using Microsoft <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> Kinect sensor and the automatic generation of furniture design recommendations using a rule-based approach. The applicability of the proposed approach is discussed through an exemplar office chair design scenario.
Effects of site-directed mutations on processing and activities of penicillin G acylase from Escherichia coli ATCC 11105 (1992)

Penicillin G acylase from Escherichia coli ATCC 11105 is synthesized from its precursor polypeptide into a catalytically active heterodimer via a complex posttranslational processing pathway. Substitutions in the pair of aminoacyl residues at the cleavage site for processing the small and large subunits were made. Their processing phenotypes and penicillin G acylase activities were analyzed. By the introduction of a prolyl residue at either position, the processing of the small subunit was blocked without a change in enzymatic activity. Four other substitutions had no effect. At the site for processing the large subunit, four substitutions out of the seven examined blocked processing. In general, penicillin G acylase activity seemed to be proportional to the efficiency of the large-subunit-processing step. Ser-290 is an amino acid critical for processing and also for the enzymatic activity of penicillin G acylase. In the mutant pAATC, in which Ser-290 is mutated to Cys, the precursor is processed, but there is no detectable enzymatic activity. This suggests that there is a difference in the structural requirements for the processing pathway and for enzymatic activity. Recombination analysis of several mutants demonstrated that the small subunit can be processed only when the large subunit is processed first. Some site-directed mutants from which signal peptides were removed showed partial processing phenotypes and reduced enzymatic activities. Their expression showed that the prerequisite for penicillin G acylase activity is the efficient processing of the large subunit and that the maturation of the small subunit does not affect the enzymatic activity.
Decimation by irrational factor using CIC filter and linear interpolation (2002)

This paper presents an efficient way to implement flexible multirate signal processing systems with high oversampling ratio and adjustable fractional or irrational sampling rate conversion ratio. One application area is a multi-standard communication receiver which should be adjustable for different symbol rates utilized in different systems. The proposed decimation filter consists of parallel CIC (cascaded integrator-comb) filters followed by a linear interpolation filter. The idea is to use two parallel CIC filters to calculate the two needed sample values for linear interpolation. These samples occur just before and after the final output sample. This corresponds to a system where the linear interpolation is done at the higher input sampling rate.
Short-term effects of bicarbonate/lactate-buffered and conventional lactate-buffered dialysis solutions on peritoneal ultrafiltration: a comparative crossover study (2008)

This study shows that the daily UF with the P solution may be lower than with the D solution. The mechanism for this short-term and reversible effect that conceivably reflects differences in biocompatibility is not clear although our results implicate that the peritoneal fluid absorption rate may differ between the two solutions.

In Vitro Specific Binding of Shiga Toxin 1 and 2 by TAK-751S (Gb3 analog) (1998)

TAK-751S is a synthetic trisaccharide coupled to Chromosorb P using a spacer sequence of 8-methoxycarboyloctyl (MCO). Its chemical structure is similar to a human receptor (Gb3) of Stx produced by enterohemorrhagic Escherichia coli (EHEC). In vitro efficacy of TAK-715S was studied by using ACHN cultured cell assay, which is sensitive and specific for measuring low level of Stx. Under various conditions, TAK-715S was mixed with purified Stx1 and Stx2, and residual free toxins in the solution were measured by using ACHN cells. TAK-715S was demonstrated to bind specifically to Stx1 and Stx2 under the condition similar to a human intestine while Chromsorb P did not bind to any Stx. The binding activity was stable in the presence of various processed foods, fresh vegetables and fruits. Antibiotics such as fosfomycin, kanamycin and norfloxacin did not disturb its binding capability. Minimum inhibitory concentrations of these antibiotics against Staphylococcus aureus FDA209P or E. coli NIHJ JC-2 neither changed after incubating with TAK-751S for 60 min at 37 degrees C. These results suggest that TAK-751S can be given orally with various foods and antibiotics for the elimination of Stx1 and Stx2 in the gut of patients with EHEC infections.
Postremission therapy in older patients with de novo acute myeloid leukemia: a randomized trial comparing mitoxantrone and intermediate-dose cytarabine with standard-dose cytarabine (2001)

The treatment of older patients with acute myeloid leukemia (AML) remains unsatisfactory, with complete remission (CR) achieved in only approximately 50% and long-term disease-free survival in 10% to 20%. Three hundred eighty-eight patients (60 years of age and older) with newly diagnosed de novo AML were randomly assigned to receive placebo (P) or granulocyte-macrophage colony-stimulating factor (GM-CSF) or GM in a double-blind manner, beginning 1 day after the completion of 3 days of daunorubicin and 7 days of cytarabine therapy. No differences were found in the rates of leukemic regrowth, CR, or infectious complications in either arm. Of 205 patients who achieved CR, 169 were medically well and were randomized to receive cytarabine alone or a combination of cytarabine and mitoxantrone. With a median follow-up of 7.7 years, the median disease-free survival times were 11 months and 10 months for those randomized to cytarabine or cytarabine/mitoxantrone, respectively. Rates of relapse, excluding deaths in CR, were 77% for cytarabine and 82% for cytarabine/mitoxantrone. Induction randomization had no effect on leukemic relapse rate or remission duration in either postremission arm. Because cytarabine/mitoxantrone was more toxic and no more effective than cytarabine, it was concluded that this higher-dose therapy had no benefit in the postremission management of older patients with de novo AML. These results suggest the need to develop novel therapeutic strategies for these patients. (Blood. 2001;98:548-553)
Vaccine Therapy for B-Cell Lymphomas: Next-Generation Strategies (2007)

Active immunotherapy is a promising approach for the treatment of lymphomas. Immunization with the clonal tumor immunoglobulin, idiotype, expressed on the surface of B-cell malignancies was associated with induction of tumor-specific cellular and humoral immunity, molecular remissions, and prolonged disease-free survival in early clinical trials. Idiotype vaccination was also demonstrated to induce tumor-specific T-cell immunity in the absence of B cells following treatment with rituximab-containing chemotherapy, suggesting that vaccines may be used in combination with rituximab. Three double-blind randomized phase 3 idiotype vaccine trials are currently ongoing to definitively determine the clinical benefit of idiotype vaccination in patients with lymphoma. Novel second-generation lymphoma vaccines are in development to streamline the production of patient-specific cancer vaccines and show encouraging results in preclinical and pilot clinical studies. To enhance the clinical efficacy of active immunotherapy, future clinical trials are likely to use a combination strategy with the lymphoma vaccine to stimulate an antitumor T-cell response and the simultaneous suppression of immune regulatory pathways to augment the induced T-cell response.
