Feeding Barley to Poultry: A Review (1992)

Barley is utilized to best advantage in poultry diets when consideration is given to the class of bird being fed and the desired level of performance. As with other cereal grains barley must be ground to achieve maximum utilization when used in poultry diets. The β-glucans inherent to most barleys can create problems for young birds and birds raised on litter. The amount of barley in broiler diets can gradually by increased as the birds become adapted to it. When poultry are fed barleybased diets, reduced variability in performance and improved growth can be obtained through the use of enzyme supplementation. Enzyme supplementation is not required in iayer diets that contain barley. However, during peak production periods barley should not be used as the sole grain components. Young turkeys responded to enzyme supplementation of barley diet with improved average daily gains and feed efficiencies.
Hierarchical Image‐Space Radiosity for Interactive Global Illumination (2009)

Abstract We introduce image‐space radiosity and a hierarchical variant as a method for interactively approximating diffuse indirect illumination in fully dynamic scenes. As oft observed, diffuse indirect illumination contains mainly low‐frequency details that do not require independent computations at every pixel. Prior work leverages this to reduce computation costs by clustering and caching samples in world or object space. This often involves scene preprocessing, complex data structures for caching, or wasted computations outside the view frustum. We instead propose clustering computations in image space, allowing the use of cheap hardware mipmapping and implicit quadtrees to allow coarser illumination computations. We build on a recently introduced multiresolution splatting technique combined with an image‐space lightcut algorithm to intelligently choose virtual point lights for an interactive, one‐bounce instant radiosity solution. Intelligently selecting point lights from our reflective shadow map enables temporally coherent illumination similar to results using more than 4096 regularly‐sampled VPLs.
Pulse Distribution Amplifier with New Pulse Re-Forming Technique (1963)

A design philosophy for a pulse distribution amplifier is developed. It is concluded that the time between leading corners of the two transitions of a pulse should be preserved, and that pulse delay — measured at a level arbitrarily close to the base of the pulse - should be independent of input rise time. A technique for reforming pulses in the desired manner is presented. A solid-state, two-output pulse distribution amplifier incorporating this technique is described.

The Mechanism of Ras GTPase Activation by Neurofibromin (2003)

Individual rate constants have been determined for each step of the Ras.GTP hydrolysis mechanism, activated by neurofibromin. Fluorescence intensity and anisotropy stopped-flow measurements used the fluorescent GTP analogue, mantGTP (2'(3')-O-(N-methylanthraniloyl)GTP), to determine rate constants for binding and release of neurofibromin. Quenched flow measurements provided the kinetics of the hydrolytic cleavage step. The fluorescent phosphate sensor, MDCC-PBP was used to measure phosphate release kinetics. Phosphate-water oxygen exchange, using (18)O-substituted GTP and inorganic phosphate (P(i)), was used to determine the extent of reversal of the hydrolysis step and of P(i) binding. The data show that neurofibromin and P(i) dissociate from the NF1.Ras.GDP.P(i) complex with identical kinetics, which are 3-fold slower than the preceding cleavage step. A model is presented in which the P(i) release is associated with the change of Ras from "GTP" to "GDP" conformation. In this model, the conformation change on P(i) release causes the large change in affinity of neurofibromin, which then dissociates rapidly.
Potent neutralization of <scp>SARS‐CoV</scp>‐2 including variants of concern by vaccines presenting the receptor‐binding domain multivalently from nanoscaffolds (2021)

The persistence of the global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has brought to the forefront the need for safe and effective vaccination strategies. In particular, the emergence of several variants with greater infectivity and resistance to current vaccines has motivated the development of a vaccine that elicits a broadly neutralizing immune response against all variants. In this study, we used a nanoparticle-based vaccine platform for the multivalent display of the receptor-binding domain (RBD) of the SARS-CoV-2 spike (S) protein, the primary target of neutralizing antibodies. Multiple copies of RBD were conjugated to the SpyCatcher-mi3 protein nanoparticle to produce a highly immunogenic nanoparticle-based vaccine. RBD-SpyCatcher-mi3 vaccines elicited broadly cross-reactive antibodies that recognized the spike proteins of not just an early isolate of SARS-CoV-2, but also three SARS-CoV-2 variants of concern as well as SARS-CoV-1. Moreover, immunization elicited high neutralizing antibody titers against an early isolate of SARS-CoV-2 as well as four variants of concern, including the delta variant. These results reveal the potential of RBD-SpyCatcher-mi3 as a broadly protective vaccination strategy.
Identification and sequence analysis of genes involved in late steps in cobalamin (vitamin B12) synthesis in Rhodobacter capsulatus (1995)

A 6.4-kb region of a 6.8-kb BamHI fragment carrying Rhodobacter capsulatus genes involved in late steps of cobalamin synthesis has been sequenced. The nucleotide sequence and genetic analysis revealed that this fragment contains eight genes arranged in at least three operons. Five of these eight genes show homology to genes involved in the cobalamin synthesis of Pseudomonas denitrificans and Salmonella typhimurium. The arrangement of these homologous genes differs considerably in the three genera. Upstream of five overlapping genes (named bluFEDCB), a promoter activity could be detected by using lacZ fusions. This promoter shows no regulation by oxygen, vitamin B12 (cobalamin), or cobinamide. Disruption of the bluE gene by a Tn5 insertion (strain AH2) results in reduced expression of the puf and puc operons, which encode pigment-binding proteins of the photosynthetic apparatus. The mutant strain AH2 can be corrected to a wild-type-like phenotype by addition of vitamin B12 or cobinamide dicyanide. Disruption of the bluB gene by an interposon (strain BB1) also disturbs the formation of the photosynthetic apparatus. The mutation of strain BB1 can be corrected by vitamin B12 but not by cobinamide. We propose that a lack of cobalamin results in deregulation and a decreased formation of the photosynthetic apparatus.
A surface micromachined electrostatic ultrasonic air transducer (1994)

We describe a technique to fabricate an electrostatic transducer using silicon surface micromachining. Using these techniques to fabricate arrays of transducers with small electrode spacing, we make efficient and broadband ultrasonic air transducers. These transducers are made using standard silicon processing techniques allowing them to be integrated, in the future, with control electronics for the fabrication of electronically scanned systems with large transducer arrays. The air transducer described in this paper operates at 1.9 MHz with an insertion loss of 26 dB (slightly worse than a reference piezoelectric transducer) and a 20% bandwidth (-4 times better than the piezoelectric transducer). The impulse response of the transducer has a short ringdown time due to the fact that the transducer has a single resonance. We present here the theory of operation, the fabrication technique used, and the characterization of the device
Enhanced Biased ASK Modulation Performance for SWIPT With AWGN Channel and Dual-Purpose Hardware (2018)

A lot of small sensors are deployed in Internet of Things applications. Simultaneous wireless information and power transfer (SWIPT) is a solution to avoid a large amount of batteries, while exchanging information with the sensors. Combining both energy harvesting and information receiving in dual-purpose hardware lowers power consumption while also decreasing sensor size. Biased amplitude shift keying (ASK) is introduced as a solution for the SWIPT modulation technique. In particular, the design of enhanced biased ASK modulation in case of an additive white Gaussian noise channel is analyzed in this paper. Novel formulas for symbol error rate are derived, while improvements of the modulation scheme are proposed based on measurements, taking rectifier nonlinearity into account and resulting in reducing the transmitted power by 14 dB for fixed error rate.

Spectroscopy of individual silicon nanowires (2003)

Photoluminescence (PL) spectroscopy of individual silicon nanowires has been investigated. A narrow emission band (85 meV) was observed associated with a fast luminescence decay in the picosecond region and is considered due to the recombination relaxation of confined electronic states. The optical anisotropy was found in the individual nanowires. When a wire was excited by linearly polarized light, the maximum intensity of linearly polarized PL was along the axis direction of the wire, and the maximum degree of polarization was determined to be 0.5. The value agrees well with the calculated one, which suggests that the polarization arise from the dielectric contrast between the crystalline cores and the silicon oxide sheathes of the nanowires.

Periodic real-time scheduling for FPGA computers (2005)

Todays reconfigurable hardware devices, such as FPGAs, have high densities and allow for the execution of several hardware tasks in parallel. This paper deals with scheduling periodic real-time tasks to such an architecture, a problem which has not been considered before. We formalize the real-time scheduling problem and propose two preemptive scheduling algorithms. The first is an adaption of the well-known earliest deadline first (EDF) technique to the FPGA execution model. The algorithm reveals good scheduling performance; task sets with system utilizations of up to 85% can be feasibly scheduled. However, the EDF approach is practical only for a small number of tasks, since there is no efficient schedulability test. The second algorithm uses the concept of servers that reserve area and execution time for other tasks. Tasks are successively merged into servers, which are then scheduled sequentially. While this method can only feasibly schedule task sets with a system utilization of up to some 50%, it is applicable to large tasks sets as the schedulability test runs in polynomial time. Equally important, the method requires only a small number of FPGA configurations which directly translates into reduced memory requirements.
Quantitative imaging with eigenfunctions of the scattering operator (2002)

An inverse scattering method that uses eigenfunctions of the scattering operator is described. This approach provides a unified framework that encompasses eigenfunction methods of focusing and quantitative image reconstruction in arbitrary media. Scattered acoustic fields are expressed using a compact, normal operator. The eigenfunctions of this operator correspond to the far-field patterns of source distributions that are directly proportional to the position-dependent contrast of a scattering object. The eigenfunctions also constitute a basis of an operator that is essentially equivalent to the time-reversal operator previously defined by others. Incident wave patterns specified by these eigenfunctions are used in a method that employs products of numerically calculated fields of the eigenfunctions to represent an unknown scattering medium. Analytic reconstruction formulas are derived both for the linearized inverse scattering problem and for the nonlinear problem in which the total acoustic pressure within the medium can be estimated. A modified eigenfunction imaging method that allows efficient reconstructions of large inhomogeneities is also presented. The methods are applied to obtain quantitative images of various scattering objects that span regions large compared to the wavelength of the acoustic illumination. The eigenfunction method is compared to the method of filtered backpropagation implemented by numerical quadrature and to Fourier inversion implemented by fast Fourier transformation. The results show the capability of the eigenfunction method to image objects with large ka. The results show the eigenfunction method is more efficient than the backpropagation method and can also be more efficient than Fourier inversion when the scattering operator has few eigenvalues.
A Bayesian Network Model for Optimizing Advertisements Allocation in Intermediate Online Targeted Advertising (2008)

Intermediate online targeted advertising (IOTA) is a new business model for online targeted advertising. Posting the right banner advertisement to the right web user at the right time is what advertisements allocation does in IOTA business model. This research uses probability theory to build a theoretical model based on Bayesian network to optimize advertisements allocation. The Bayesian network model allows us to calculate the probability that Web user will click the banner based on historical data. And these can help us to make optimal decision in advertisements allocation. Data availability is also be discussed in this paper. An experiment base on practical data is run to verify the feasibility of the Bayesian network model.
Amino acid sequence of acyl-CoA-binding protein from cow liver (1987)

Acyl-CoA-binding protein from bovine liver was purified with the use of reverse-phase h.p.l.c. in the final step. The complete amino acid sequence was determined by using a combination of gas-phase Edman degradation and electron-impact and fast-atom-bombardment mass spectrometry. The sequence was confirmed by determination of the Mr by plasma-desorption time-of-flight mass spectrometry.
A biomimetic method for extracting leukocytes from blood in microfluidic devices (2003)

The extraction of leukocytes from blood to be processed by micro-assay systems must be performed using methods which can be executed using minimal sample sizes and few preparatory steps. This demonstration proposes a biomimetic approach to performing this function using the adhesive rolling that is mediated by the interaction between a special class of proteins and ligands expressed by leukocytes but not red cells. The surfaces of microstructured flow channels made using standard microfabrication techniques can be coated with one or more of these adhesive proteins. These proteins facilitate the capture of leukocytes from blood samples sent through these channels. Captured cells are not immobilized but are restricted to slow rolling while blood passes rapidly through the channels. Eventually leukocytes become enriched and isolated as the rest of the blood is eluted through the channel. This study demonstrates the capture of HL-60 cells on E-selectin coated surfaces and quantities their transit through two prospective designs for microstructured flow channels. Results show that white cells can be enriched greatly over initial density and that flow geometry strongly influences the transit of the captured cells.
Stress-induced urticaria associated with local anesthetic administration. (1984)

A case is reported in which chronic urticaria developed following local anesthetic administration in a 21-year old Chinese-American male who had presented for routine dental care. An in-depth medical history and intradermal skin-testing failed to disclose a reason for this reaction. Referral to an allergist revealed a previously unknown underlying emotional tension which contributed to the development of chronic urticaria. A brief trial of hydroxyzine (Vistaril), an antihistaminic and anxiolytic medication, was successful in controlling this condition. This case illustrates the importance of the evaluation of the emotional status as a vital component of a comprehensive medical history.
[<sup>11</sup>C]Carbon Monoxide in Selenium-Mediated Synthesis of <sup>11</sup>C-Carbamoyl Compounds (2002)

Using either amines, amino alcohols, or alcohols in selenium-mediated synthesis with [(11)C]carbon monoxide, 3 ureas, 6 carbamates, and 1 carbonate were labeled. Tetrabutylammonium fluoride ((TBA)F) was discovered to form a soluble and reactive complex with selenium and drastically increase the radiochemical yields. Of the selected carbamoyl compounds, one was a receptor ligand, one was an enzyme inhibitor, and one was a muscular relaxant pharmaceutical. The (11)C-target compounds were obtained in radiochemical yields ranging from low to almost quantitative and with specific radioactivity up to 1300 GBq/micromol. The radiochemical purity of the final products exceeded 98%. In one case, the corresponding (13)C-substituted compound was produced to verify the position of the (11)C-label. In a typical experiment starting with 16.4 GBq [(11)C]carbon monoxide, 7.0 GBq of LC-purified 5-phenyl-1,3-oxazolidin-[2-(11)C]-2-one was obtained within 20 min from start of the carbonylation reaction (84% decay-corrected radiochemical yield). The presented approach is an interesting alternative to the use of [(11)C]phosgene in labeling chemistry.
Synergistic Reinforcement of Graphene Oxide-polyvinyl Alcohol Bionanocomposite to Enhance Mechanical Performance (2019)

Due to excessive depletion of natural sources, it is mandatory to exploit biopolymer nanocomposites to get rid of hazardous environmental issues. In this work, GO is used as nanofiller reinforcement in PVA matrix which has been fabricated via solution casting methodology (a biomimetic approach). The results showed that a small amount of graphene oxide content could enhance the mechanical as well as thermal properties of PVA-GO nanocomposites. At 1.5% GO addition, tensile strength of 69 MPa is observed which is very high in comparison to pristine PVA. SEM morphology revealed homogeneous dispersion of GO nanoparticles throughout the polymer matrix. AFM topography examined the increase in roughness on addition of nanofiller. Thermal stability is increased on integration of GO nanoparticles. The resultant nanocomposites are well suited for structural and packaging applications.

Cytokine and chemokine responses following pulmonary challenge with Aspergillus fumigatus: obligatory role of TNF-α and GM-CSF in neutrophil recruitment (1999)

Aspergillus fumigatus causes life-threatening invasive pulmonary aspergillosis in the immunocompromised patient. In this study we have used a murine model of intratracheal challenge with A. fumigatus to investigate the recruitment of inflammatory cells in the lung and the expression of proinflammatory cytokines and chemokines. Our results show that A. fumigatus causes an acute pulmonary inflammatory response which is dominated by neutrophils and to a lesser extent macrophages. During the peak of infection, proinflammatory cytokines (TNF-alpha, GM-CSF and IL-1beta) and chemokines (MIP-1alpha, MCP-1 and MIP-2), are induced within the lung. Furthermore, treatment of mice with neutralizing anti-TNF-alpha and anti-GM-CSF mAbs reduced the influx of neutrophils into the lung and delayed fungal clearance. Our observations show that Aspergillus conidia are effective inducers of host chemokine responses both in vitro and in vivo. Furthermore, TNF-alpha and GM-CSF play a central role in the recruitment of neutrophils into the lung in response to this clinically important pathogen.
Native Simulation of MPSoC Using Hardware-Assisted Virtualization (2012)

Integration of multiple heterogeneous processors into a single system-on-a-chip is a clear trend in embedded devices. Designing and verifying these devices requires high-speed and easy-to-build simulation platforms. Among the software simulation approaches, native simulation is a good candidate since the embedded software is executed natively on the host machine, and no instruction set simulator development effort is necessary. However, existing native simulation approaches are such that the simulated software shares the memory space of the modeled hardware modules and the host operating system, making impractical the support of legacy code running on the target platform. To overcome this issue seldom mentioned in the literature, we propose the addition of a transparent address space translation layer to separate the target address space from the host simulator one. For this, we exploit the hardware-assisted virtualization technology now available on most general-purpose processors. Experiments show that this solution does not degrade the native simulation speed, while keeping the ability to accomplish software performance evaluation.
Über die Synthese und Reaktionen von (<i>O</i>‐Acylaminophenyl)‐glyoxylsäureamiden (1982)

Abstract Über die Synthese einer Reihe von ( o ‐Acylaminophenyl)glyoxylsäureamiden 2 und 3 aus N ‐Acylisatinen 1 und den daraus zugänglichen Folgeprodukten wird berichtet. Durch Reduktion mit NaBH 4 oder LiAlH 4 sind o ‐(Acylamino)mandelsäureamide 5 oder o (Alkylamino)mandelsäureamide 7 sowie substituierte Phenethanolamine 9 zugänglich. Kondensation von 1a . 2 und 3 mit primären Aminen führt zu den Iminoverbindungen 10 , deren katalytische Hydrierung einen Zugang zu den substituierten 3,4‐Dihydrochinazolinen 12 oder Phenylglycinamiden 11 eröffnet. Auch die Piperazinon‐Ringsysteme 15 und 16 lassen sich auf diesem Wege herstellen.
