A multiple sidelobe canceler using tapped delay line with Gram‐Schmidt processing (1999)

In a multiple sidelobe canceler (MSLC) designed to suppress several interference waves incident on the radar, the number of auxiliary antennas equal to or greater than the number of interference waves is needed. On the other hand, in the TDL (Tapped Delay Line)-MSLC using delay lines, only one auxiliary antenna is needed, and hence this system is economical, with the further advantage that the convergence time for the adaptive weights does not depend on the directions of incidence of the interference waves. In this paper, for the case where two interference waves are incident on a TDL-MSLC with one delay line, the relation between the convergence time of the adaptive weights and the product of the time delay in the delay line and the frequency difference of two interference waves is investigated. Furthermore, a TDL-MSLC using Gram-Schmidt processing is proposed. It is confirmed by simulations and hardware experiments that this configuration can reduce the effect of the frequency difference of the two interference waves on the convergence time of the adaptive weights, so that the convergence of the adaptive weights can be made faster. © 1999 Scripta Technica, Electron Comm Jpn Pt 1, 82(5): 24–33, 1999
Preparation and characterization of new optically active poly(amide-imide)s and poly(ester-imide)s containing calix[4]arene units (2014)

This article describes the synthesis and characterization of new optically active polymers containing upper rim calix[4]arene from the polycondensation reaction of 5,11,17,23-tetra-tert-butyl-25,27-bis[(4-aminobenzyloxy)-6,28-dihydroxy] calix[4]arene with N,N′-pyromellitoylimido-bis-L-alanine diacid chloride (6a) and N,N′-pyromellitoylimido-bis-L-phenyl alanine diacid chloride (6b). This optically active diacidchlorides 6a and 6b have been prepared from the reaction of pyromellitic dianhydride with two chiral amino acids, alanine and phenyl alanine. The chiral poly(amide-imide)s and poly(ester-imide)s obtained in good yield and moderate inherent viscosity. All the polymers have been fully characterized by FTIR, 1H NMR spectroscopy and elemental analysis.

Effects of spray-dried egg albumin on growth performance of early-weaned pigs (1998)

Seventy two early-weaned pigs (initially 12.4 lb) were used in a 14-d growth trial to evaluate a control diet (no added spray-dried egg albumin or animal plasma) or the control diet with 5% spray-dried plasma, 7% spraydried egg albumin~ or 2.5% spray-dried plasma plus 3.5% spray-dried egg albumin. Pigs fed 5% spray-dried animal plasma had greater ADG and improved F/G compared with those fed 7% spray-dried egg albumin, whereas pigs fed the control or a blend of spray-dried egg albumin plus spray-dried animal plasma had intermediate performance. These results suggest that the spray-dried egg albumin used is not an effective replacement for spray-dried animal plasma in diets for early-weaned pigs.; Swine Day, Manhattan, KS, November 19, 1998

GraalBench (2004)

In this paper we consider implementations of embedded 3D graphics and provide evidence indicating that 3D benchmarks employed for desktop computers are not suitable for mobile environments. Consequently, we present GraalBench, a set of 3D graphics workloads representative for contemporary and emerging mobile devices. In addition, we present detailed simulation results for a typical rasterization pipeline. The results show that the proposed benchmarks use only a part of the resources offered by current 3D graphics libraries. For instance, while each benchmark uses the texturing unit for more than 70% of the generated fragments, the alpha unit is employed for less than 13% of the fragments. The Fog unit was used for 84% of the fragments by one benchmark, but the other benchmarks did not use it at all. Our experiments on the proposed suite suggest that the texturing, depth and blending units should be implemented in hardware, while, for instance, the dithering unit may be omitted from a hardware implementation. Finally, we discuss the architectural implications of the obtained results for hardware implementations.
Comparison of Adsorptive Removal of Total Nitrogen (T-N) and Total Phosphorous (T-P) in Aqueous Solution using Granular Activated Charcoal (GAC) (2013)

The present study is to explore the possibility of utilizing granular activated charcoal (GAC) for the removal of total phosphorous (T-P) and total nitrogen (T-N) in aqueous solution. Batch adsorption studies were carried out to determine the influences of various factors like initial concentration, contact time and temperature. The adsorption data showed that GAC has a similar adsorption capacity for both T-N and T-P. The adsorption degree of T-N and T-P on GAC was highly concentration dependent. It was found that the adsorption capacity of GAC is quite favorable at a low concentration. At concentrations of 1.0 mg L-1 of T-P and 2.0 mg L-1 of T-N, approximately 97 % of adsorption was achieved by GAC. The equilibrium data were fitted well to the Langmuir isotherm model. The pseudo-second-order kinetic model appeared to be the better-fitting model because it has higher R2 compared with the pseudo-first-order and intra-particle kinetic model. The theoretical adsorption equilibrium qe,cal from pseudo-second-order kinetic model were relatively similar to the experimental adsorption equilibrium qe,exp. To evaluate the effect of thermodynamic parameters at different temperatures, the change in free energy ΔG, the enthalpy ΔH and the entropy ΔS were estimated. Except for adsorption of T-P at 278 K, the ΔG values obtained were all negative at the investigated temperatures. It indicates that the present adsorption system occurs spontaneously. The adsorption process of T-N by GAC was exothermic in nature, whereas T-P showed endothermic behavior. In addition, the positive values of ΔS imply that there was the increase in the randomness of adsorption of T-N and T-P at GAC-solution interface.

Palm-size low-level neutron sensor for radiation monitoring (1996)

We have developed a new technique for the detection of neutrons in the presence of a high gamma-ray background. This was accomplished by using two lithium-loaded glass scintillators (/sup 6/Li//sup 7/Li) in combination. The neutron capture reaction in /sup 6/Li has a very high Q-value which means better discrimination against gamma-ray background. The /sup 7/Li detector, on the other hand, is neutron insensitive and was used to measure separately the gamma contribution in a mixed neutron-gamma field. By subtracting this gamma contribution from the /sup 6/Li data, which is sensitive to both gamma rays and neutrons, one can obtain the pure neutron counts.

The Pawpaw Regional Variety Trial (1999)

Pawpaw is the only temperate member of the tropical Custard Apple family (Bailey 1960), which includes several delicious tropical fruits such as the custard apple ( Annona reticulata L.), cherimoya (A. cherimola Mill.), sweetsop or sugar apple ( A. squamosa L.), atemoya (A. squamosa ◊ A. cherimola), and soursop (A. muricata L.). There are also eight other members of the Asimina genus that are native to the extreme southeastern states of Florida and Georgia. These include A. incarna (Bartr.) Exell. (flag pawpaw); A. longifolia Kral; A. obovata (Willd.) Nash; A. parviflora (Michx.) Dunal (dwarf pawpaw); A. pygmaea (Bartr.) Dunal; A. reticulata Shuttlw. ex Chapman; A. tetramera Small (opossum pawpaw); and A. ◊ nashii Kral (Kral 1960). Description of the Plant Pawpaw is a small, deciduous tree that may attain 5 to 10 m in height and tends to be found in patches due to root suckering (Layne 1996). In sunny locations, trees typically assume a pyramidal habit, with a straight trunk and lush, dark green, long, drooping leaves (Fig. 2). The blossoms occur singly on the previous year’s wood, reaching up to 5 cm in diameter, emerging before leaves in mid spring (about April in Kentucky). Flowers have a globular androecium and a gynoecium composed of 3‐7 carpels or 3‐7 fruited clusters (Kral 1960). Flowers are strongly protogynous, self-incompatible and require cross-pollination (Wilson and Schemske 1980), although some trees may be self-compatible. Pollination may be by flies (Wilson and Schemske 1980) and beetles (Kral 1960).
Photocontrol of Peptide Function: Backbone Cyclization Strategy with Photocleavable Amino Acid (2011)

Light-switchable peptide: The combination of cyclization and a photocleavable amino acid provides a potentially versatile strategy for the photocontrol of peptide function. Upon photoirradiation, photoactivatable cyclic matrix metalloproteinase-3 inhibitor peptide (MMPI) was degraded to give the corresponding linear product (see scheme), which showed 47-fold stronger activity than the parent cyclic MMPI.

Two-Cell Downlink Noncoherent Cooperation without Transmitter Phase Alignment (2010)

Multicell joint processing can mitigate inter-cell interference and thereby increase the spectral efficiency of cellular systems. Most previous work has assumed phase-aligned (coherent) transmissions from different base stations (BSTs), which is difficult to achieve in practice. In this work, a noncoherent cooperative transmission scheme for the downlink is studied, which does not require phase alignment. We consider two adjacent cells each with a single user, and assume that the BSTs share their messages through a dedicated link. Each BST transmits a superposition of two codewords, one for each receiver. Each receiver decodes its own message, and treats the signals for the other receiver as background noise. With narrowband transmissions the achievable rate region and maximum achievable weighted sum rate are characterized by optimizing the power allocation at each BST between its two codewords. For a wideband (multicarrier) system, a dual formulation of the optimal power allocation problem across subcarriers is presented, which admits efficient numerical solution. Results show that the proposed cooperation scheme can improve the sum rate substantially at low to moderate signal-to-noise ratios.
Adaptive thresholding for visual attention and tracking systems (2004)

A simple adaptive thresholding circuit for visual attention and tracking applications is presented. When used in visual attention systems or in tracking systems, the circuit allows "background" inhibition and false alarm reduction. A test chip with an eight-element adaptive thresholding circuit has been implemented in a standard 0.5-µm CMOS process and is operated via a 3.3-V supply in the saturation region. The circuit architecture is discussed, operation in saturation and subthreshold regions are explained, and measurements from a test chip are reported.

Rapid dissolution of ZnO nanocrystals in acidic cancer microenvironment leading to preferential apoptosis (2011)

The microenvironment of cancer plays a very critical role in the survival, proliferation and drug resistance of solid tumors. Here, we report an interesting, acidic cancer microenvironment-mediated dissolution-induced preferential toxicity of ZnO nanocrystals (NCs) against cancer cells while leaving primary cells unaffected. Irrespective of the size-scale (5 and 200 nm) and surface chemistry differences (silica, starch or polyethylene glycol coating), ZnO NCs exhibited multiple stress mechanisms against cancer cell lines (IC(50)∼150 μM) while normal human primary cells (human dermal fibroblast, lymphocytes, human umbilical vein endothelial cells) remain less affected. Flow cytometry and confocal microscopy studies revealed that ZnO NCs undergo rapid preferential dissolution in acidic (pH ∼5-6) cancer microenvironment causing elevated ROS stress, mitochondrial superoxide formation, depolarization of mitochondrial membrane, and cell cycle arrest at S/G2 phase leading to apoptosis. In effect, by elucidating the unique toxicity mechanism of ZnO NCs, we show that ZnO NCs can destabilize cancer cells by utilizing its own hostile acidic microenvironment, which is otherwise critical for its survival.
Dynamic ensemble selection and instantaneous pruning for regression. (2014)

Abstract. A novel dynamic method of selecting pruned ensembles of predictors for regression problems is presented. The proposed method, known henceforth as DESIP, enhances the prediction accuracy and generalization ability of pruning methods. Pruning heuristics attempt to combine accurate yet complementary members, therefore DESIP enhances the performance by modifying the pruned aggregation through distributing the ensemble member selection over the entire dataset. Four static ensemble pruning approaches used in regression are compared to highlight the performance improvement yielded by the dynamic method. Experimental comparison is made using Multiple Layer Perceptron predictors on benchmark datasets. 1
Proteomic profiling of cerebrospinal fluid in canine degenerative myelopathy (2013)

Canine degenerative myelopathy (DM) is an incurable, progressive disease of the canine spinal cord that has similarities with human amyotrophic lateral sclerosis (ALS). Onset is typically after the age of 7 years and was reported initially to occur frequently in the German shepherd dog, although recent reports on DM in Pembroke Welsh corgi, and boxer dog has also emerged (Coates and Wininger, 2010). Progressive weakness and incoordination of the rear limbs are often the first signs seen in affected dogs, with progression over time to complete paralysis with elective euthanasia the outcome (Johnston et al., 2000).
The Effects of Androgens and Estrogen on the Mechanical Properties of Bone in the Aged Ovariectomized Rat (1996)

Abstract Sex steroids regulate normal bone metabolism. Deficiency of gonadal hormones in both males and females leads to osteopenia and osteoporosis (1,2). Estrogen is necessary for maintaining bone density in pre- and post-menopausal women, but the role of androgen is still unclear. The effects of testosterone and anabolic steroids on bone in women appear to be positive (3). There is also data supporting a positive effect of androgens on bone maintenance in ovariectomized rats. Testosterone can be converted to estrogen in vivo, unlike its metabolite 5 alpha dihydrotestosterone (DHT), which also binds to androgen receptors with high affinity. The objective of this study was to determine the effects of a non-aromatizable androgen (DHT) alone, or in combination with estrogen, on mechanical properties of cortical and trabeular bone in the aged ovariectomized female rat.
Evaluation von ischämie-typischen biliären Komplikationen (ITBL) mit der Magnetresonanz-Cholangiopankreatikographie (MRCP): Welche Sequenz eignet sich am besten? (2009)

Use of a Highly Sensitive and Specific Immunoradiometric Assay for Detection of Human Chorionic Gonadotropin in Urine of Normal, Nonpregnaiit, and Pregnant Individuals* (1984)

A highly sensitive and specific two-site immunoradiometric assay (IRMA) for hCG has been developed and applied to the detection of the hormone in the urine of normal nonpregnant and pregnant individuals. The IRMA uses a solid phase coupled monoclonal antibody to the hCG beta-subunit for extraction of hormone from urine. The hCG extracted is then directly quantified by the binding of an affinity purified and radiolabeled rabbit antibody that reacts with the unique COOH-terminal peptide region of the hCG beta-subunit. The assay is capable of reliably and accurately measuring as little as 0.01 ng hCG/ml urine without interference from hLH. Assays of urine from normal men and nonpregnant women of reproductive age indicated that most individuals did not have detectable levels of hCG immunoreactivity, although a minority had minute amounts, with a mean value of approximately 0.01 ng hCG/mg creatinine. In contrast, all normal menopausal women studied had easily detectable levels of hCG immunoreactivity in their urine, with a mean value of 0.123 ng hCG/mg creatinine. A study of the excretion of hCG from three men injected with hormone for treatment of infertility indicated that after the first 24 h, hCG was cleared with a single exponential rate and was detectable to a level of 0.01 ng/ml. Application of the IRMA to measurements of hCG in the urine of two artificially inseminated patients indicated that the method was capable of detecting pregnancy as early as 9 days postovulation. The extreme sensitivity and specificity of the IRMA for urinary hCG in conjunction with the simplicity of assay performance and specimen collection should provide a substantial advantage over currently available methods for detection of early pregnancy and tumor monitoring.
Mechanical Thrombectomy Is Now the Gold Standard for Acute Ischemic Stroke: Implications for Routine Clinical Practice (2015)

Questions remain over the applicability of mechanical thrombectomy to stroke subgroups including wake-up strokes and basilar artery thrombosis. The role of imaging is integral to this process and can lead to broadening eligibility criteria in the future. Workflow practices have been streamlined in the 5 positive randomized controlled studies, but guidelines will need to be revised accordingly if similar patient outcomes are to be replicated in a wider population.
