UC Cooperative Extension sensory analysis panel enhances the quality of California olive oil (2011)

California's olive oil industry has evolved from primarily a salvage operation of the table olive industry to a producer of world-class, premium, extra-virgin olive oil. In 1997, UC Cooperative Extension started the first California olive oil taste panel, which was officially recognized by the International Olive Council in 2001. Specific protocols were used to screen potential panelists and train them to identify defects and positive characteristics, identical to 43 other world taste panels. The UCCE panel helped the California Olive Oil Council develop a seal certification program using sensory analysis. Certification provides consumers with assurance that labeled oils are free of defects and warrant the “extra virgin” grade. Sensory evaluation using a unique UCCE profile sheet provides complete and detailed information about specific positive flavor characteristics of olive cultivars grown in California. The UCCE sensory panel has also contributed to a better understanding of the qualities of California olive oil and advancement of the industry by participating in research on pest management, cultural practices and processing.
On the synthesis of lattice parameter digital filters (1984)

The synthesis of lattice parameter digital filters from a given <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">z</tex> -transform transfer function is considered. Included are several versions of AR, MA, and ARMA structures. The approach is based upon partial fraction expansions and leads to numerical algorithms for parameter calculation which are numerically robust in terms of zeros and poles close to the unit circle as well as self-correcting for finite precision coefficients.
The Discrete Wavelet Transform: Wedding the . (1992)

In a general sense this paper represents an effort to clarify the relationship of discrete and continuous wavelet transforms. More narrowly, it focuses on bringing together two separately motivated implementations of the wavelet trans- form, the algorithme U trous and Mallat's multiresolution de- composition. It is observed that these algorithms are both spe- cial cases of a single filter bank structure, the discrete wavelet transform, the behavior of which is governed by one's choice of filters. In fact, the h trow algorithm, originally devised as a computationally efficient implementation, is more properly viewed as a nonorthonormal multiresolution algorithm for which the discrete wavelet transform is exact. Moreover, it is shown that the commonly used Lagrange i~ trous filters are in one-to-one correspondence with the convolutional squares of the Daubechies filters for orthonormal wavelets of compact support. A systematic framework for the discrete wavelet transform is provided, and conditions are derived under which it com- putes the continuous wavelet transform exactly. Suitable filter constraints for finite energy and boundedness of the discrete transform are also derived. Finally, relevant signal processing parameters are examined, and it is remarked that orthonor- mality is balanced by restrictions on resolution.
Post-Synthesis Functionalization of Porous Organic Polymers for CO2 Capture (2014)

Solid porous materials are network materials that contain space void. Porous Organic Polymers (POPs) are porous materials, which are constructed from organic building blocks and exhibit large surface area with low densities. Due to these characteristics, POPs have attracted attentions because of their potential use in application such as gas storage and chemical separation. This thesis presents a study of the synthesis of novel POP being a network based on 2,5- dibromobenzaldehyde and 1,3,5-triethynylbenzene linked together via Sonogashira- Hagihara (SH) coupling. This network showed a relatively good surface area of 770 m2/g and total pore volume of 0.59 cc/g. In addition, it proved to be chemically and thermally stable, maintaining the thermal stability up to 350oC. In addition to synthesize novel aldehyde-POP network, it was also possible to post synthetically modify a network via one-step post synthetic functionalization by amine. Ethelynediamine (EDA), Diethylenetriamine (DETA), and Tris(2-aminoethyl)amine (Tris-amine) are three different amines used for aldehyde-POP functionalization. The produced networks were aminated via different amine species substitution the aldehyde group present within the network. Modification to these networks resulted in a decrease in surface area from 770 m2.g-1 to 333 m2.g-1, 162 m2.g-1, and 211 m2.g-1 in respective to EDA, DETA, and Tris-amine. Although the surface areas were decreased, the CO2 adsorption was enhanced as evidenced by the increase of Qst (i.e., from 25 to 45 kJ.mol-1 for DETA at low coverage). Our findings are expected to strengthen existing research areas of the influence of different type of amines (e.g aromatic amine) on CO2 adsorption. Although amine grafting has been studied in other systems (e.g., PAFs and MOFs), we are the first to reported amine functionalized POPs using a novel one-step amine grafting PSM procedure. Future research might extend to study the interaction between CO2 and amine species under real working conditions.

Identification of a Hierarchy of Multipotent Hematopoietic Progenitors in Human Cord Blood. (2007)

Abstract Mouse hematopoiesis is initiated by long-term hematopoietic stem cells (HSC) that differentiate into a series of multipotent progenitors that exhibit progressively diminished self-renewal ability. In human hematopoiesis, populations enriched for HSC have been identified, as have downstream lineage-committed progenitors, but not multipotent progenitors. Previous reports indicate that human HSC are enriched in Lin-CD34+CD38- cord blood and bone marrow, and express CD90. We demonstrate that the Lin-CD34+CD38- fraction of cord blood and bone marrow can be subdivided into three subpopulations: CD90+CD45RA-, CD90-CD45RA-, and CD90-CD45RA+. While, the function of the CD90- subpopulations is unknown, the CD90+CD45RA- subpopulation presumably contains HSC. We report here in vitro and in vivo functional studies of these three subpopulations from normal human cord blood. In vitro, CD90+CD45RA- cells formed all types of myeloid colonies in methylcellulose and were able to replate with 70% efficiency. CD90-CD45RA- cells also formed all types of myeloid colonies, but replated with only 33% efficiency. CD90-CD45RA+ cells failed to form myeloid colonies in methylcellulose. In liquid culture, CD90+CD45RA- cells gave rise to all three subpopulations; CD90-CD45RA- cells gave rise to both CD90- subpopulations, but not CD90+ cells; CD90-CD45RA+ cells gave rise to themselves only. These data establish an in vitro differentiation hierarchy from CD90+CD45RA- to CD90-CD45RA- to CD90-CD45RA+ cells among Lin-CD34+CD38- cord blood. In vivo, xenotransplantation of CD90+CD45RA- cells into NOD/SCID/IL-2R?-null newborn mice resulted in long-term multilineage engraftment with transplantation of as few as 10 purified cells. Secondary transplants from primary engrafted mice also resulted in long-term multilineage engraftment, indicating the presence of self-renewing HSC. Transplantation of CD90-CD45RA- cells also resulted in long-term multilineage engraftment; however, secondary transplants did not reliably result in long-term engraftment, indicating a reduced capacity for self-renewal. Transplantation of CD90-CD45RA+ cells did not result in any detectable human hematopoietic cells, indicating that the function of these cells is undetermined. Finally, transplantation of limiting numbers of CD90-CD45RA- cells (less than 100) resulted in multilineage human engraftment at 4 weeks, that was no longer detectable by 12 weeks. Thus, the CD90-CD45RA- subpopulation is capable of multilineage differentiation while exhibiting limited self-renewal ability. We believe this study represents the first prospective identification of a population of human multipotent progenitors, Lin-CD34+CD38-CD90-CD45RA- cord blood.
PESE: an efficient partition-based electrical simulation environment (2002)

Due to the performance limitations of electrical level circuit simulators, the number of design circuits that cannot be analyzed but need to be simulated at the electrical level are increasing. Hence, extensive research has been carried out with the aim of improving simulation performance for large and complex circuits. This paper introduces a new environment for electrical level simulation with high performance. PESE uses circuit partitioning based on the channel connectedness, in conjunction with a standard electrical simulator like SPICE, to provide a greater simulation speed with less memory requirement while maintaining the desired level of electrical accuracy. The size of circuits PESE can handle is not limited, and the speedup is expected to grow with the circuit size while having much less memory space requirement. Several benchmark circuits have been tested and the results show that PESE provides accurate simulation capability with a speed and memory space advantage.
Pure-shear mode BAW resonators consisting of (11-20)textured ZnO films (2008)

Thickness pure-shear mode film bulk acoustic wave resonators (FBARs) made of (11-20) textured ZnO films have been fabricated. We have also fabricated FBAR structure consisting of two layers of the (11-20) textured ZnO film with opposite polarization directions. This FBAR structure operated in second overtone pure-shear mode, and allowed shear-mode FBARs at higher frequency. The effective electromechanical coupling coefficients keff2 of pure-shear mode FBAR and second overtone pure-shear mode FBAR in this study were found to be 3.3% and 0.8%, respectively. The temperature coefficient of frequency (TCF) of thickness extensional mode FBAR, pure-shear mode FBAR, and second overtone pure-shear mode FBAR were measured in the temperature range of 10-60 °C. TCF values of -63.1 ppm/°C, -34.7 ppm/°C, and -35.6 ppm/°C were found for the thickness extensional mode FBAR, the pure-shear mode FBAR, and the second overtone pure-shear mode FBAR, respectively. These results demonstrated that pure-shear mode ZnO FBARs have more stable temperature characteristics than the conventional thickness extensional mode ZnO FBARs.
A moderate but not total decrease of mitochondrial membrane potential triggers apoptosis in neuron-like cells (2000)

The effects of various degrees of perturbation of the mitochondrial membrane potential (mt delta psi) on apoptosis was investigated by intensified fluorescence digital-imaging microscopy on neuron-like cells, ND7. Mt delta psi was either decreased by 40% by the protonophore carbonyl cyanide p-trifluoromethoxyphenylhydrazone (FCCP 100 nM, 15 min) or completely collapsed (FCCP 10 microM, 60 min). A moderate decrease of mt delta psi induced a reduction of mitochondrial NADH, followed by exposure of phosphatidyl serine and then by chromatin condensation, 36% of nuclei being condensed 60 min after FCCP treatment. During these stages, mitochondrion morphology was fully preserved. In contrast, no chromatin condensation was observed after a rapid and total dissipation of mt delta psi. These results suggest that a partial decrease of mt delta psi would allow mitochondrial functions required to trigger apoptosis to be sustained.
On the Grid Sensitivity of the Wall Boundary Condition of the k-ω Turbulence Model (2004)

This paper presents a study on the k-ω turbulence model with regard to the numerical implementation of the ω boundary condition at a solid wall, where ω tends to infinity. Three different implementations are tested in the calculation of a simple two-dimensional turbulent flow over a flat plate. Grid refinement studies in grids with different near-wall grid line spacings are performed to assess the numerical uncertainty of the predicted drag coefficient CD. The results are compared with the predictions of several alternative algebraic, one-equation, and two-equation eddy-viscosity turbulence models. For the same level of grid refinement, the estimated uncertainty of CD obtained with the k-ω model is one order of magnitude larger than for all the other models.
Multihormonal Regulation of Insulin-Like Growth Factor-Binding Protein-1 in Rat H4IIE Hepatoma Cells: The Dominant Role of Insulin* (1991)

Circulating levels of insulin-like growth factor-binding protein-1 (IGFBP-1) and the abundance of hepatic IGFBP-1 mRNA are increased in streptozotocin-diabetic rats and are regulated in accordance with insulin and metabolic status. We recently purified rat IGFBP-1 from medium conditioned by well differentiated rat H4IIE hepatoma cells. Since this cell line provides a useful model for examining the effects of hormones on hepatocellular function, we used H4IIE cells to examine the relative role that insulin and other factors may play in the regulation of IGFBP-1 production. H4IIE cells were stabilized in serum-free medium, then treated with specific hormones. The availability of IGFBPs in conditioned medium was estimated by [125I]IGF-I binding assay, and specific BPs were assessed by Western ligand and immunoblot analyses. The abundance of IGFBP-1 mRNA was determined by Northern and slot blot analysis. Initial studies revealed that [125I]IGF-I-binding activity in conditioned medium was reduced after 24-h incubation with 100 nM insulin (52 +/- 4% of control; P less than 0.001). In contrast, binding activity was increased after only 4 h of incubation with 75 microM 8-(4-chlorophenylthio)cAMP (8-CPT-cAMP) or 1 microM dexamethasone (P less than 0.001 vs. control for each), but these effects were prevented by insulin. Ligand and immunoblotting demonstrated that insulin decreased the production of 32K and 34K forms of IGFBP-1, while both 8-CPT-cAMP and dexamethasone increased the production of IGFBP-1; again, insulin prevented the effects of 8-CPT-cAMP and dexamethasone. Of note, 1 microM rat GH, testosterone, progesterone, or 17 beta-estradiol had no effect on either IGF-binding activity or IGFBP-1 production. Northern and slot blot analyses revealed that 100 nM insulin profoundly lowered the abundance of IGFBP-1 mRNA in H4IIE cells (4 +/- 0.6% of control at 4 h; P less than 0.001), while IGFBP-1 mRNA was increased 2-fold during incubation with 75 microM 8-CPT-cAMP (P less than 0.001) and 9-fold with 1 microM dexamethasone (P less than 0.001). Once again, the effect of insulin was dominant; insulin both prevented and reversed the effects of maximally effective concentrations of 8-CPT-cAMP and dexamethasone. To determine whether this effect of insulin reflected altered generation or stability of IGFBP-1 mRNA, H4IIE cells were incubated with 2.5 micrograms/ml actinomycin-D with or without insulin, and mRNA was quantitated by Northern blot.(ABSTRACT TRUNCATED AT 400 WORDS)
Optimum low-voltage silicon power switches fabricated using scaled trench MOS technologies (2002)

Optimum low-voltage silicon power MOSFET technologies with forward conductivities approaching the silicon limit are presented. Vertical scaled trench power MOSFETs with measured performances of V/sub DB/=55 V (R/sub sp/=0.2 m Omega -cm/sup 2/, k/sub DEV/=5.7 Omega pF) and V/sub DB/=35 V (R/sub sp/=0.15 m Omega -cm/sup 2/, k/sub DEV/=4.3 Omega -pF) were developed, where V/sub DB/ is the drain-source avalanche breakdown voltage, R/sub sp/ is the specific on-state resistance, and K/sub DEV/ is the input device technology factor. Measured performances are in excellent agreement with detailed two-dimensional device simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nonablative Wrinkle Treatment of the Face and Neck Using a Combined Diode Laser and Radiofrequency Technology (2005)

Background Nonablative laser systems that integrate optical and conducted radiofrequency (RF) energies are a novel technology for the treatment of wrinkles. Objective This two-center study investigated the safety and effectiveness of combination diode laser (900 nm) and RF for the treatment of wrinkles and skin texture. Methods Patients with grade II to IV wrinkling on the face, according to the Glogau classification system, were treated with a combination diode laser and RF using a fluence of 30 to 50 J/cm2 and RF energy of 80 to 100 J/cm3. Patients received up to three treatment sessions at 2- to 3-week time intervals. Wrinkle assessments using the Glogau scale were conducted at baseline and at 3 months following the last treatment. In addition, patients and physicians graded the level of improvement using pre- and post-treatment photographs. Results Twenty-three subjects completed all three treatment sessions. Of these participants, more than 50% had a greater than 50% improvement in the appearance of wrinkles. All subjects reported a noticeable improvement in skin smoothness and texture. Conclusion This preliminary study demonstrates that the combination of diode laser and RF energies decreases the appearance of wrinkles and improves skin texture.
Solubilization of Lymphocytes (2003)

Purification and study of transmembrane proteins require isolation of these structures from their lipid environment. This isolation is carried out through the use of detergents. In this unit, several approaches to solubilization of membrane proteins are presented. Solubilization of whole lymphocytes, using conditions aimed at minimizing the disruption of protein-protein interactions, is described with an optional step that may be useful when the disruption of protein interactions is desired as part of a purification protocol. In some situations, it may be desirable to purify membranes prior to their solubilization or to determine the physical relationship between proteins, which can be accomplished by a cross-linking.
Tumor suppressor miR-181c attenuates proliferation, invasion, and self-renewal abilities in glioblastoma (2014)

Glioblastoma multiforme (GBM) is well known for its aggressiveness, but the underlying mechanisms are unclear, limiting the treatment. In the present study, we showed that miR-181c, a commonly downregulated miRNA in GBM reported by several miRNA profiles, was associated with the mesenchymal subtype of GBM and predicted the outcome for patients from a GBM cohort (n=518) obtained from The Cancer Genome Atlas database. A multivariate analysis showed that miR-181c was an independent prognostic indicator for GBM patients. Quantitative reverse transcription PCR showed that miR-181c was expressed poorly in neurospheres of glioma cells that resemble glioma stem cells. Proliferation and invasion assays showed that miR-181c also blocked the proliferation and invasion abilities of glioma cells. Limiting dilution and colony formation assays showed that miR-181c attenuated the self-renewal ability of glioma cells. Finally, investigation of the mechanism defined Notch2, a key molecular of Notch signaling, as the functional downstream target of miR-181c. An inverse correlation was found between miR-181c and Notch2 in glioma cells and verified in fresh glioma samples. Taken together, the present study showed that miR-181c can be considered a valuable indicator for the outcome of GBM patients. miR-181c acts as a tumor suppressor that attenuates proliferation, invasion, and self-renewal capacities by downregulation of Notch2 in glioma cells.
Delay of Surgery (1972)

Faced with the stress of suffering an inguinal hernia, some patients delay surgery longer than others do. Two personality measures (and one demographic variable, race) were used to predict both a) delay of surgery and b) reasons given for electing surgery now. Several controversies in coping style and internal-external control theory were explored, and applications were suggested for public health problems.
Properties of Cold Work Tool Steel Shot Peened by 1200 <I>HV</I>-Class Fe-Cr-B Gas Atomized Powder as Shot Peening Media (2010)

Shot peening is widely used for automobile parts such as springs and gears to improve fatigue strength. In general, high hardness media is required for shot peening to targets with high hardness. Recently, shot peening to various tool steels such as cold and hot tool steels and high speed tool steel has been investigated and is used in some applications, and improvements in fatigue strength and die life by the increase of compressive residual stress and hardness at their shot peened surface have been reported.In this study, the properties of cold work tool steel shot peened by Fe-8%Cr-6.5%B (mass%) gas atomized powder (FeCrB powder) with 1200 HV-class Vickers hardness and long life as shot peening media were examined. Quenched and tempered JIS-SKD11 followed by shot peening by FeCrB and high speed steel powder sieved between 45 and 125 μm was used.Vickers hardness and compressive residual stress of the shot peened JIS-SKD11 surface by FeCrB powder were higher than these by high speed steel powder. As a result, JIS-SKD11 shot peened by FeCrB powder showed excellent fatigue property, Charpy impact value and wear resistance property.

Evolutionary stasis of M1 gene of human influenza A viruses and the possibility of their subtyping by restriction analysis of M1 gene polymerase chain reaction product. (1997)

Nucleotide (nt) and amino acid (aa) sequences of the M1 protein in 36 human influenza A viruses were analyzed. The neighbor joining tree of the nt sequences revealed several lineages associated with past epidemics of human influenza. However, the tree of aa sequences revealed only few specific lineages. This discrepancy in phylogeny between nt and aa sequences indicates that the M1 protein of human influenza A virus nearly reached an evolutionary stasis. A simple subtyping method of human influenza A viruses by restriction fragment length polymorphism (RFLP) analysis of M1 gene polymerase chain reaction (PCR) products is discussed.
