Corn Silage Management III: Effects of Hybrid, Maturity, and Processing on Nitrogen Metabolism and Ruminal Fermentation (2002)

Two experiments were conducted to evaluate the effects of maturity and mechanical processing of two hybrids of whole plant corn silage on DM and OM digestibility, nitrogen metabolism, ruminal fermentation, and milk production and composition in lactating Holstein cows. In the first experiment, Pioneer hybrid 3845 whole plant corn was harvested at hard dough, one-third milkline, and two-thirds milkline with a theoretical length-of-cut of 6.4 mm. At each stage of maturity, corn was harvested with (1-mm roll clearance) and without (15.9-mm roll clearance) mechanical processing using a John Deere 5830 harvester with an on-board kernel processor. In the second experiment, Pioneer hybrids 3845 and Quanta were harvested at one-third milkline, two-thirds milkline, and blackline stages of maturity with and without mechanical processing. The theoretical length-of-cut was 12.7 mm. Total tract DM and OM digestibilities were lower for cows fed diets containing processed corn silage in experiment 1, and tended to be lower for cows fed diets containing unprocessed corn silage in experiment 2. Ruminal acetate concentrations were greater and ruminal propionate concentrations were lower 2 and 6 h after feeding for cows fed diets containing corn silage harvested at physiological maturity in experiment 2. This was due to decreased digestion of starch at advanced maturities in experiment 2. Ruminal pH tended to decline rapidly after feeding for cows fed hybrid Quanta (2 h) compared to hybrid 3845 (5 h) corn silage based diets. Ruminal acetate concentrations decreased and ruminal propionate concentrations increased 2 and 6 h after feeding for cows fed diets containing hybrid Quanta corn silage compared to hybrid 3845 corn silage. This was related to a greater starch concentration in the corn silage, greater starch intake, and increased rate of starch digestion for cows fed hybrid Quanta corn silage-based diets. Microbial nitrogen flow was lower and feed nitrogen flow was greater for cows fed diets containing hybrid Quanta corn silage. The lower microbial nitrogen flow was due to lower microbial nitrogen concentration and nonammonia nitrogen flow to the duodenum. Milk fat and protein concentrations had a strong quadratic relationship with forage NDF intake as a percentage of body weight. When forage NDF intake as a percentage of body weight dropped below 0.70%, there was a rapid decline in milk fat and protein concentrations.

Chemistry and Biochemistry of Pituitary Endorphins (1979)

Correlation has been demonstrated between the analgesic potency, receptor binding properties, preferred solution conformation and metabolic stability of natural and synthetic opioid peptides. Of several factors contributing to the analgesic effect, preference has been given to the improved receptor binding affinity and specificity provided by either a putative hydrophobic bonding between the C- and N- terminal parts of β -endorphin, or the occurrence of Pro at the C-terminus of some superactive enkephalin analogs. Progress has been made in the isolation and characterization of a particle-bound pituitary endopeptidase involved in the generation of β-endorphin from β-lipotropic hormone.
Efficient and Compact 50kW Gen2 SiC Device Based PV String Inverter (2014)

Using newly available Gen2 family of Silicon Carbide (SiC) power MOSFET devices, it is possible to develop a highly efficient and compact 50kW grid tied solar inverter. The efficient new devices allowed the designers to develop a high power to weight ratio 1kW/kg for an air-cooled 50kW 3-ph photovoltaic (PV) inverter with an MPPT boost function. The 50 kW interleaved boost circuit used was only 7 kg, and peak efficiency of 99.4% while switching at 75 kHz. Besides being more efficient, the new SiC based inverter can be less than half the weight and size of state of the art commercial 50kW systems available today.
Using the Locus of Control Personality Dimension as a Predictor of Online Behavior (2002)

Since the 16 th century, the availability of communication technology has advanced the level and accessibility of commerce and personal freedoms. The advent of the computer as a personal communication tool has given individuals new power in their ability to communicate, gain information, and make decisions. A major paradigm shift has been in the control that the individual now has in a consumer role. The internet has provided consumers a vehicle by which they can actively participate in the decision-making process – from need recognition to post-purchase evaluation. Little research has been done to explore the personality characteristics of internet users. This study examines one aspect of personality, locus of control, and internet behavior. Research findings reveal substantial differences in internet usage and attitudes between a consumer's internal or external locus of control orientation. Results and future research relative to this study are discussed.
Hyaluronic acid coatings as a simple and efficient approach to improve MSC homing toward the site of inflammation (2017)

A major challenge in regenerative medicine is to improve therapeutic cells' delivery and targeting using an efficient and simple protocol. Mesenchymal stem cells (MSC) are currently employed for the treatment of inflammatory-based diseases, due to their powerful immunosoppressive potential. Here we report a simple and versatile method to transiently overexpress the hyaluronic acid (HA) receptor, CD44, on MSC membranes, to improve their homing potential towards an inflammatory site without affecting their behavior. The effect of HA-coatings on murine MSC was functionally determined both, in vitro and in vivo as a consequence of the transient CD44 overexpression induced by HA. Data obtained from the in vitro migration assay demonstrated a two-fold increase in the migratory potential of HA-treated MSC compared to untreated cells. In an LPS-induced inflamed ear murine model, HA-treated MSC demonstrated a significantly higher inflammatory targeting as observed at 72 hrs as compared to untreated cells. This increased accumulation for HA-treated MSC yielded a substantial reduction in inflammation as demonstrated by the decrease in the expression of pro-inflammatory markers and by the induction of a pro-regenerative environment.
Green-noise halftoning with dot diffusion (2007)

Dot diffusion is a halftoning technique that is based on the traditional error diffusion concept, but offers a high degree of parallel processing by its block based approach. Traditional dot diffusion however suffers from periodicity artifacts. To limit the visibility of these artifacts, we propose grid diffusion, which applies different class matrices for different blocks. Furthermore, in this paper we will discuss two approaches in the dot diffusion framework to generate green-noise halftone patterns. The first approach is based on output dependent feedback (hysteresis), analogous to the standard green-noise error diffusion techniques. We observe that the resulting halftones are rather coarse and highly dependent on the used dot diffusion class matrices. In the second approach we don't limit the diffusion to the nearest neighbors. This leads to less coarse halftones, compared to the first approach. The drawback is that it can only cope with rather limited cluster sizes. We can reduce these drawbacks by combining the two approaches.
Isolation and Immunochemical Properties of Haptenic Material from Timothy Pollen (1964)

Summary The isolation of a fraction (WST-Fr2) from the dialysate of timothy grass pollen extract is described. This fraction (WST-Fr2) appears homogenous by chromatography on Sephadex-G25, Amberlite IRC-50 and electrophoresis, but immunologically heterogenous as demonstrated by inhibition of several lines of precipitation in agar diffusion. WST-Fr2 possesses haptenic properties as demonstrated by its inhibition of specific precipitation and inhibition of the formation of lines of precipitation in agar diffusions. The results indicate the importance of considering the possible presence and significance of haptenic material in pollen extracts for laboratory studies as well as for clinical use.
Accuracy of Sine Wave Frequency Estimation by Multipoint Interpolated DFT Approach (2010)

This paper focuses on the frequency-domain estimation of the normalized frequency of a sine wave corrupted by a stationary white noise. The weighted multipoint interpolated discrete Fourier transform method is considered, and its effect on both the spectral interference due to the image component and the additive wideband noise is taken into account. In particular, the expression of the combined standard uncertainty of the estimator is derived in the case when the H-term maximum sidelobe decay window (H ≥ 2) is used, and the number of interpolation points is 2J + 1 (J ≥ 1). Based on this expression, the number of interpolation points that minimize the estimator-combined uncertainty can be determined. The derived results are validated by means of computer simulations and applied to experimental data.
Nonlinear optical reorientation in hybrid aligned nematics (1984)

We give the complete theory of optically induced molecular reorientation in hybrid aligned nematic liquid crystals in which all the approximations usually adopted can be dropped. Applying a very general variational method of calculation and taking into account the anchoring energies on the boundaries of the liquid crystal cell we obtain a phase diagram (thickness versus optical field) exhibiting the possibility of ordered phase transitions from homeotropic to hybrid to planar configurations. Then we get the field dependent dielectric constant 〈δε〉 for any field strength and work out, as well, some numerical examples. In particular we show the previously assumed quadratic dependence on the field is true only at very low fields while a saturation occurs increasing the field. For larger sample thicknesses the saturation occurs at fields much lower than those necessary for the transition to a planar order. Finally we show that our analysis can be applied to the study of optical Fredericksz transitions in nematics and we work out a more general expression for the Fredericksz threshold.

Advanced Evaluation of Transitional Zones for Drilling Optimization (2002)

Abstract The paper reviews tectonic influence on pore pressure distribution in overpressured sealing zones, and their recognition on logs. Based on materials from West Siberia (Russia) and Gulf-of-Mexico (Texas and Louisiana) a study of tectonic and diagenetic impact on transitional zones forming and associated drilling problems is performed. Faults play an important role in overpressure forming, but they can also cause partial or total damage of the seal. A fault can enhance sealing properties of shale cap or partially destroy them, allow «escape» of formation fluids and pressures from down-dip formations, forming a shallow overpressure zone (Matagorda Island 622/623 and East Cameroon). Various stages of shale diagenesis are related to water expulsion and can aid to abnormally height formation pressure forming. A nature of Bazenov abnormal pressure is related to TOC (total organic carbon) alteration, specifically to hydrocarbon generation. This overpressure was "translated" into Abalak shaly formation with complex fractured-cavernous reservoirs (Severo-Demyanskoe, Em-Egovskoe fields). Both events are causing drilling problems and could be recognized on NMR (nuclear-magnetic resonance) and conventional (resistivity, gamma-ray) log diagrams. By incorporating such information into the drilling model one can characterize complex formations and avoid them when possible from penetrating.
Prevention of Edema in Long Flights with Pycnogenol® (2005)

The aim of this study was to evaluate the prevention of edema during long-haul flights with an oral, anti-edema and antithrombotic agent (Pycnogenol, Horphag, Research Management SA, Geneva, Switzerland) in asymptomatic subjects. The assessment of edema was performed by evaluating an analogue scale, the rate of ankle swelling by strain-gauge derived rate of ankle swelling (RAS), and by assessing the ankle circumference variation. The study included 211 subjects; 169 completed the study (88 in the control group and 81 in the Pycnogenol group). There were no important differences between the two groups (comparable for age, gender, weight, body mass index, and pattern distribution). The edema score, the RAS, and the circumference at inclusion were also comparable. After the flight in those treated with Pycnogenol, the edema score was increased only by 17.9% (vs. an increase of 58.3% in the control group) (p<0.05). The RAS, evaluated in 22 subjects in the Pycnogenol group (age 44.5; SD 8) and in 23 in the control group (age 45; SD 9) was increased on average by 91% in the control group and 36% in the Pycnogenol group (p<0.05). The variation on circumference at the ankle was 6% in the Pycnogenol group (11% in the control group; p<0.05). These results indicate a positive effect of Pycnogenol on edema during long flights when considering subjective and objective data. No unwanted effects were observed.
Robust transmit strategies for multiantenna bidirectional broadcast channels (2012)

In this work the multiantenna bidirectional broadcast channel under channel uncertainty is studied. This problem is motivated by the broadcast phase of the decode-and-forward bidirectional relaying protocol, where a relay node establishes a bidirectional communication between two other nodes while having only imperfect channel state information available. Different uncertainty models are investigated, where the nominal channels experience either a multiplicative or additive perturbation based on a spectral norm constraint. For these uncertainty models the corresponding capacity regions of the multiantenna bidirectional broadcast channel are analyzed. Further, robust transmit strategies are characterized and worst-case perturbations are identified.
Surgical Technique for the Clarion® Cochlear Implant (1999)

This paper describes a technique for implantation of the CLARION Multi-Strategy Cochlear Implant based upon the authors' surgical experience with the device. Although much of the procedure is similar to many commonly performed otologic operations, including implantation of other cochlear prostheses, several device-specific modifications are highlighted. Those modifications include a substantial bony seat, facial recess, and cochleostomy, and the use of an electrode insertion tool.
A Class of Cationic Triblock Amphiphilic Oligopeptides as Efficient Gene‐Delivery Vectors (2008)

A new class of triblock oligopeptides, containing arginine for DNA binding, histidine for intracellular buffering, and hydrophobic residues for enhanced cellular uptake has been designed, with each block offering unique functionalities essential for efficient gene delivery. Together, these materials demonstrate strong DNA binding ability, low cytotoxicity, and significantly higher in vivo gene-transfection efficiency compared to the PEI standard.

Human c<i>-fgr</i> Induces a Monocyte-Specific Enzyme in NIH 3T3 Cells (1991)

The mutant c-fgr protein (p58c-fgr/F523) containing Phe-523 instead of Tyr-523 exhibited transforming activity in NIH 3T3 cells like other protein-tyrosine kinases of the src family, but normal p58c-fgr (p58c-fgr/wt) did not. The mutant protein showed tyrosine kinase activity threefold higher than that of the normal protein in vitro. Surprisingly, transfection of the normal c-fgr gene into NIH 3T3 cells resulted in induction of sodium fluoride (NaF)-sensitive alpha-naphthyl butyrate esterase (alpha-NBE), a marker enzyme of cells of monocytic origin, which was not induced in v-src-, v-fgr-, or lyn-transfected NIH 3T3 cells. The NaF-sensitive alpha-NBE induced in c-fgr transfectants was shown by isoelectric focusing to have a pI of 5.2 to 5.4, a range which was the same as those for thioglycolate-induced murine peritoneal macrophages and 1 alpha,25-dihydroxyvitamin D3-treated WEHI-3B cells. Immunoblotting studies with antiphosphotyrosine antibodies revealed that 58-, 62-, 75-, 120-, 200-, and 230-kDa proteins were commonly phosphorylated at tyrosine residues in NIH 3T3 cells transfected with normal and mutated c-fgr, while 95-kDa protein was significantly phosphorylated at tyrosine residues in cells transfected with the mutated c-fgr. These findings suggest that tyrosine phosphorylation of specific cellular substrate proteins is important in induction of NaF-sensitive alpha-NBE and cell transformation by p58c-fgr.
Modular verification of data abstractions with shared realizations (1994)

Presents a method for the modular specification and verification of data abstractions in which multiple abstract objects share a common realization level data structure. Such shared realizations are an important implementation technique for data abstractions, because they provide for efficient use of memory; i.e., they allow the amount of memory allocated to the realization of an abstract object to be dynamic, so that only the amount of memory needed for its realization is allocated to it at any one time. To be explicit, an example of this kind of data abstraction is given. Although a number of programming languages provide good support for shared realizations, there has been limited research on its specification and verification. An important property of The authors' method is that it allows data abstractions to be dealt with modularly; i.e., each data abstraction can be specified and verified individually. Its abstract specification is made available for use by other program modules, but all of its implementation details are hidden, which simplifies the verification of code that uses the abstraction. The authors have developed semantics for data abstractions and their method of specification, and have used it to prove that their verification method is logically sound and relatively complete in the sense of Cook (1978). The use of shared realizations impacts specification and verification in several related ways. The manipulation of one abstract object may inadvertently produce a side effect on other abstract objects. Without shared realizations, such unwanted side effects can be prevented by scoping rules, but this is not possible with shared realizations. Instead, the absence of such side effects must be explicitly proven by the verification method. This requires the specification language to provide for quantification over the currently active (allocated) instances of an abstract type that is not necessary for the specification of less advanced implementations of data abstractions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Aberrant class switching juxtaposes c-myc with a middle repetitive element (LINE) and an IgH intron in two spontaneously arising rat immunocytomas. (1988)

Our previous studies of spontaneously arising rat immunocytomas of the Lou/Wsl strain have shown that Ig switch regions are frequently the targets for c-myc recombination. In several tumors, however, we were unable to show recombination of the c-myc with Ig switch regions. We have cloned the rearranged c-myc fragments from 2 of these tumors, IR209 and IR223, and found that the c-myc recombines with a LINE region in the IR209 and with intron 1 of the epsilon locus in the IR223. Although switch regions are not found at the breakpoints, the sequences at the breakpoints share limited homology with Ig switch recognition sequences. This suggests that the switch recombinase enzymes are able to recognize sequences in addition to the defined switch recombination sites. At the same time, both the LINE and epsilon intron 1 sequences are located within the Ig cluster, providing further evidence for the selection of c-myc activation by Ig sequences in the pathogenesis of rat immunocytoma, mouse plasmacytoma, and Burkitt's lymphoma.
Anthocyanin Pigments of Rhubarb, Canada Red (1968)

SUMMARY The anthocyanin pigments of rhubarb ( Rheum rhaponticum ‘Canada Red’) were extracted with 0.02% methanolic HCI and partially purified by use of cation‐exchange resin. The pigments were separated into two bands with paper and cellulose thin‐layer chromatography. The purified pigments were characterized by their R, values, partial acid hydrolysis, identification of the aglycones and sugars after complete hydrolysis, and their spectral properties. The main pigment (87% of the total anthocyanins) was identified as cyanidin‐3‐glucoside and the second (13%) is proposed to be cyanidin‐3‐rutinoside.
