Apparent digestibility and retention of nutrients bound to phytate complexes as influenced by microbial phytase and feeding regimen in pigs (1994)

Five barrows of approximately 45 kg BW, fitted with post-valvular T-cecum cannulas at the ileo-cecal junction, were assigned randomly to five treatments (5 x 5 Latin square design) to assess the effect of microbial phytase and feeding regimen (frequency and level) on the apparent digestibilities (total tract [ATTD] and ileal [AID]) and retention of nutrients. A corn-tapioca-soybean meal diet of low intrinsic phytase activity, containing no added inorganic P, was fed either without or with microbial phytase from Aspergillus niger var. Van Tieghem (800 phytase units/kg of diet) at different feeding frequencies (once, twice, or seven times per day) and feeding levels (2.3 vs 2.8 times the maintenance requirement for ME, i.e., 418 kJ ME/BW.75). Microbial phytase enhanced significantly the ATTD of DM, OM, CP, Ca, total P, and amino acids (except for cystine and proline). Also, the AID of total P, phytic acid, methionine, and arginine was increased (P < .05 or .01). As a consequence of adding this enzyme, the retention (grams/day) of N, Ca, and P was greater (P < .01) and their daily excretion was diminished by 5.5, 2.2, and 1.9 g/d, respectively. The feeding level exerted a minor effect on the ATTD and AID (except for methionine and cystine), although the retention (grams/day) of N, Ca, and P was greater (P < .01) at the higher level of feeding. The feeding frequency influenced significantly the ATTD of Ca, tryptophan, and isoleucine and the AID of phytic acid, cystine, arginine, isoleucine, and phenylalanine. Also, N retention (grams/day) was reduced in pigs fed once daily (P < .01).
On the estimation of global motion using phase correlation for broadcast applications (1999)

Global motion estimation attempts to find and compensate for camera pan, zoom, rotation or other motions. The majority of motion existing in a video scene consists of local motion coupled with the camera motion; compensating for global motion improves the accuracy of local motion estimation allowing it to search for object motions only. Applications include video compression, background mosaicing and camera vibration reduction. The aim of this paper is to compare different ways of using the phase correlation approach for the estimation of global motion. To investigate this further, we have decided to experiment with three previously undocumented techniques and one that is a variant of the method described by Reddy and Chatterji (see IEEE Trans. on Image Processing, vol.5, no.8, p.1266-71, 1996): (1) phase correlation for rotation and scale (PCRS) on a global basis; (2) PCRS using subsampled images; (3) extended PCRS across multiresolution images; and (4) block PCRS from local estimates.
Enhancement of backprojection SAR imagery using digital spotlighting preprocessing (2004)

This paper examines signal processing methods for improving the fidelity of backprojection SAR imagery using a preprocessing method that suppresses Doppler aliasing as well as other side lobe artifacts that are introduced by the radar radiation pattern. The algorithm, known as digital spotlighting, imposes a filtering scheme on the azimuth-compressed SAR data, and manipulates the resultant spectral data to achieve a higher PRF to suppress the Doppler aliasing. The merits of the algorithm are studied using the ARL boom-SAR data.
New perspectives on the functional anatomical organization of the basolateral amygdala (1989)

We have examined the functional anatomical organization of the basolateral amygdaloid nucleus (BL) in the rat and guinea pig using combined light and electron microscopic methods. Afferent and efferent connections as well as the internal organization of the BL have been studied with combined tracing, immunohistochemical, and Golgi techniques. We have found that the BL receives an intense cholinergic innervation from the ventral forebrain cholinergic system and, for the first time, described a group of intrinsic cholinergic neurons in the BL. The innervation from the primary olfactory cortex and the thalamus, as well as the GABAergic innervation of the amygdalostriatal projection neurons, is also described. Electron microscopic analyses have shown that the cholinergic system as well as the thalamic afferents primarily innervate the distal dendritic arbor of the projection neurons in the BL, whereas the GABAergic fibers are directed primarily towards their soma and proximal dendrites. Correlated light and electron microscopic studies have revealed that the projection neurons in the BL share many features with pyramidal and spiny stellate cells in the cerebral cortex. The ultrastructural characteristics of the afferent fiber systems and of the non-projection neurons in the BL are also reminiscent of the situation in the cerebral cortex. The observations reported in this study lend further support to the concept of a cortical-like organization of the BL. The anatomical observations of the BL are discussed particularly in relation to three major forebrain systems: 1. the ventral striatopallidal system, 2. the continuum formed by the centromedial amygdala, the substantia innominata and the bed nucleus of the stria terminalis, and 3. the cholinergic ventral forebrain system. The clinical implications of the results obtained in this series of experimental studies are discussed in relation to Alzheimer's disease and complex partial seizures. The cholinergic system, in particular, has attracted much interest in relation to senile dementia of Alzheimer's type (SDAT), which often seems to be characterized by disruption of the ventral forebrain cholinergic projection system. We have found that the cholinergic innervation of the BL is often significantly reduced in SDAT, but interestingly enough, the areas of the basolateral amygdala with the highest content of cholinergic markers contain the smallest numbers of senile plaques.
Identification of a target RNA motif for RNA-binding protein HuR (2004)

HuR, a protein that binds to specific mRNA subsets, is increasingly recognized as a pivotal posttranscriptional regulator of gene expression. Here, HuR was immunoprecipitated under conditions that preserved HuR-RNA interactions, and HuR-bound target mRNAs were identified by cDNA array hybridization. Analysis of primary sequences and secondary structures shared among HuR targets led to the identification of a 17- to 20-base-long RNA motif rich in uracils. This HuR motif was found in almost all mRNAs previously reported to be HuR targets, was located preferentially within 3′ untranslated regions of all unigene transcripts examined, and was conserved in >50% of human and mouse homologous genes. Importantly, the HuR motif allowed the successful prediction and subsequent validation of novel HuR targets from gene databases. This study describes an HuR target RNA motif and presents a general strategy for identifying target motifs for RNA-binding proteins.
Smart Workbench: A multimodal and bidirectional assistance system for industrial application (2015)

Manual tasks in industrial production are often monotonous, leading to a decrease in concentration and motivation of the worker and thus to deficiencies in the products. With quality as well as performance requirements getting more and more stringent, workers need additional support by their work environment. We developed a novel approach providing worker assistance and inline quality assurance for manual workplaces. The prototypical system Smart Workbench (SWoB) uses a multimodal sensor interface consisting of a 3D depth sensor in combination with a 2D camera to control quality aspects of the product and track the work progress. The bidirectional flow of information is handled via an image processing driven gestural interface and the displaying of advice directly on the work surface. In this paper the developed system is introduced and the current state of evaluating its industrial usage with a manual quality control and packaging task reported.
Platelet‐Rich Plasma: A Milieu of Bioactive Factors (2012)

Platelet concentrates such as platelet-rich plasma (PRP) have gained popularity in sports medicine and orthopaedics to promote accelerated physiologic healing and return to function. Each PRP product varies depending on patient factors and the system used to generate it. Blood from some patients may fail to make PRP, and most clinicians use PRP without performing cell counts on either the blood or the preparation to confirm that the solution is truly PRP. Components in this milieu have bioactive functions that affect musculoskeletal tissue regeneration and healing. Platelets are activated by collagen or other molecules and release growth factors from alpha granules. Additional substances are released from dense bodies and lysosomes. Soluble proteins also present in PRP function in hemostasis, whereas others serve as biomarkers of musculoskeletal injury. Electrolytes and soluble plasma hormones are required for cellular signaling and regulation. Leukocytes and erythrocytes are present in PRP and function in inflammation, immunity, and additional cellular signaling pathways. This article supports the emerging paradigm that more than just platelets are playing a role in clinical responses to PRP. Depending on the specific constituents of a PRP preparation, the clinical use can theoretically be matched to the pathology being treated in an effort to improve clinical efficacy.
Determination of stabilizing feedback gains for second-order systems with time delay (2001)

In this paper we consider the problem of stabilizing a second-order plant with dead-time using a constant gain controller. Due to the presence of the time delay, the number of roots of the characteristic equation of the closed-loop system is infinite, making the problem posed in this paper a difficult one. A complete analytical characterization of all stabilizing feedback gains is provided using a version of the Hermite-Biehler Theorem applicable to quasipolynomials. Both open-loop stable and unstable plants are considered. The results reported in this paper will serve as a stepping stone for tackling the more complicated cases of stabilization using a PI or a PID controller.
Continuous speech recognition with neural networks and stationary-transitional acoustic units (2002)

This paper proposes the use of a kind of acoustic units named stationary-transitional units within a hybrid hidden Markov model/neural network recognition framework as an alternative to standard context-independent phonemes. These units are made up of stationary parts of the context independent phonemes plus all the admissible transitions between them and represent a partition of the sounds of the language, like phonemes, but with more acoustic detail. These units are very suitable to be modeled with neural networks and their use may enhance the performances of hybrid HMM-NN systems by increasing their acoustic resolution. This hypothesis is verified for the Italian language, experimenting these units on a difficult domain of spontaneous speech recognition, namely railway timetable vocal access with the Dialogos system. The results show that a relevant improvement is achieved with respects to the use of the standard context independent phonemes.
Expression of Zonulin, c-kit, and Glial Fibrillary Acidic Protein in Human Gliomas (2009)

The hallmarks of human malignant gliomas are their marked invasiveness and vascularity. Because angiogenesis and tumor invasion have been associated with extracellular matrix degradation and intercellular tight junctions, the involvement of zonulin in glioma biology is in the focus. We selected for histological examination five cases of glioblastoma WHO IV (nomenclature of the World Health Organization) and one case each from astrocytoma WHO III, meningioma WHO III, and meningioma WHO I as control samples. The meningioma WHO I is regarded as benign, whereas the meningioma WHO III is recognized as the transition form of malignant tumors in humans. The visualization of a newly designed antibody against human zonulin was studied in triple-labeling studies using fluorescence immunocytochemistry and compared with the expression of c-kit and glial fibrillary acidic protein in differently developed human gliomas. We found that increasing the expression of c-kit is accompanied by an increase of zonulin expression. Both are correlated to the degree of malignancy of human brain tumors. The expression of zonulin is correlated to the degradation of the blood-brain barrier as revealed by Griffonia simplicifolia lectin. In differently graded tumors, we found differently graded involvement of blood vessels in the tumor development, explaining patients' survival.
The Emergence of Ug99 Races of the Stem Rust Fungus is a Threat to World Wheat Production (2011)

Race Ug99 of the fungus Puccinia graminis tritici that causes stem or black rust disease on wheat was first detected in Uganda in 1998. Seven races belonging to the Ug99 lineage are now known and have spread to various wheat-growing countries in the eastern African highlands, as well as Zimbabwe, South Africa, Sudan, Yemen, and Iran. Because of the susceptibility of 90% of the wheat varieties grown worldwide, the Ug99 group of races was recognized as a major threat to wheat production and food security. Its spread, either wind-mediated or human-aided, to other countries in Africa, Asia, and beyond is evident. Screening in Kenya and Ethiopia has identified a low frequency of resistant wheat varieties and breeding materials. Identification and transfer of new sources of race-specific resistance from various wheat relatives is underway to enhance the diversity of resistance. Although new Ug99-resistant varieties that yield more than current popular varieties are being released and promoted, major efforts are required to displace current Ug99 susceptible varieties with varieties that have diverse race-specific or durable resistance and mitigate the Ug99 threat.
Identification of an OprD Homologue in <i>Acinetobacter </i><i>b</i><i>aumannii</i> (2005)

With the increased number of resistant Acinetobacter baumannii strains, it is urgently required to decipher the molecular bases of outer membrane permeability. The analyses of the outer membrane from different A. baumannii strains indicated a modification in the expression of two proteins of 29 and 43 kDa, respectively. By electrophoresis and MALDI-MS analyses, the 43 kDa OMP was identified as a protein belonging to the OprD family, a basic amino acid and imipenem porin.

Auto-Retoucher(ART)—A Framework for Background Replacement and Foreground Adjustment (2019)

Replacing the background and simultaneously adjusting foreground objects is a challenging task in image editing. Current techniques for generating such images are heavily relied on user interactions with image editing softwares, which is a tedious job for professional retouchers. Some exciting progress on image editing has been made to ease their workload. However, few models focused on guarantee the semantic consistency between the foreground and background. To solve this problem, we propose a framework - ART (Auto-Retoucher) to generate images with sufficient semantic and spatial consistency from a given image. Inputs are first processed by semantic matting and scene parsing modules, then a multi-task verifier model will give two confidence scores for the current matching and foreground location. We demonstrate that our jointly optimized verifier model successfully guides the foreground adjustment and improves the global visual consistency.
Multiscale Carbon Structures Fabricated by Direct Micropatterning of Electrospun Mats of SU-8 Photoresist Nanofibers (2010)

A novel method for the direct fabrication of arrays of micropatterned polymeric and carbon nanofiber structures on any substrate is developed. First SU-8, an epoxy-based negative photoresist, is electrospun under optimized conditions to produce a layer of polymeric nanofibers. Next, this nanofibrous mat is micropatterned using photolithography, and finally, pyrolysis produces ordered arrays of microdomains containing carbon nanofibers. The nanotextured surfaces of carbon nanofibers are shown to be very hydrophobic (water contact angle approximately 130 degrees). Micropatterning thus generates a substantial wettability contrast of nanofiber domains with intervening micropatches of very hydrophilic carbon (approximately 20 degrees) or silicon substrates.
Differential Angle Scanning Surface Plasmon Resonance Detection (2018)

In this paper, we propose a differential angle-scanning SPR detection approach for an enhanced signal to noise ratio, a fast angle decision calculation, and a wide dynamic range. With a proof-of-concept experimental setup, we measured the SPR characteristics for air, D.I. water, and sucrose solutions, and discussed for the numerous angle decision algorithms and methods, such as second or third-order polynomial fits and centroid algorithms for the SPR dip detection, and a simple linear fit for the differential SPR slope detection. Overall performances for signal-to-noise ratio, sensitivity, resolution and dynamic range are also discussed.
Detection of replication-competent adenoviruses spiked into recombinant adenovirus vector products by infectivity PCR (2003)

The presence of replication-competent adenovirus (RCA) in clinical lots of adenovirus vectors raises a variety of safety concerns. To detect RCA in adenovirus vector products, the cell culture/cytopathic effect (CPE) method has generally been preferred. However, it is difficult to evaluate the amount of RCA clearly and quantitatively by this method. In addition, the cell culture/CPE method requires large-scale cell culturing and a substantial amount of time. For the purpose of establishing a method to detect RCA more sensitively and rapidly, we developed the infectivity PCR, a hybrid method that combines the infectivity assay and quantitative PCR. This method allows RCA to be quantified by real-time quantitative PCR using primers and a probe designed for E1 DNA. By infectivity PCR, 1 pfu of RCA spiked into 10(9) particles of adenovirus vectors could be detected. In contrast, CPE was observed in the cells infected with 10(4) pfu of RCA spiked into 10(9) particles of adenovirus vectors. The glass-beads method was suitable for extracting DNA rapidly from the RCA-infected cells. These results showed that infectivity PCR combined with the glass-beads-based DNA extraction method was useful for the detection of RCA in adenovirus vector products.
Ovarian Morphology and Endocrine Characteristics of Female Sheep Fetuses that are Heterozygous or Homozygous for the Inverdale Prolificacy Gene(fecX' (1997)

The Inverdale gene (fecX1), located on the X chromosome, is a major gene affecting the ovulation rate of sheep. At each ovulation, ewes heterozygous (I+) for the fecX1 gene ovulate, on average, one more egg than noncarriers (++), whereas ewes that are homozygous (II) for this gene are infertile and have "streak" ovaries. Since formation of the ovary occurs in fetal life, it is possible that the fecX1 gene influences ovarian development before birth. The aims of this study were to examine the effects of the fecX1 gene on germ cell development, follicular formation and growth, and plasma gonadotropin concentrations at 5 different days of gestation (i.e., Days 40, 90, 105, 120, and 135) and also in adult life. The results suggest that one copy of the X-linked mutation in female fetuses leads to a retardation of germ cell development at Days 40 and 90 of gestation. However, from Day 105 of gestation, follicular formation and growth appear normal. By contrast, in females with two copies of the X-linked mutation, germ cell development and follicular formation appear normal, but thereafter follicular growth from the primary stage of development is impaired. During fetal life the plasma concentrations of FSH and LH, although not measurable at Day 40, were similar between all the genotypes at Day 105, 120, and 135 of gestation. The only exception was for LH at Day 90 in the I+ and II animals: in ewes with these genotypes the plasma concentrations of LH were similar but significantly lower (p < 0.01) than in the ++ genotype. In adult animals the plasma concentrations of FSH and LH were not different between the ++ and I+ genotypes, reflecting similar levels of ovarian follicular activity. However, in adult II animals, the plasma concentrations of FSH and LH were significantly higher (both p < 0.01) than in the ++ and I+ genotypes, reflecting the absence of normal secondary and antral follicles. In summary, these data show that the fecX1 gene affects ovarian development before birth and that the nature of the effect is influenced by whether the female fetus is a homozygous or heterozygous carrier of the X-linked mutation.
Compiler‐assisted full checkpointing (1994)

Abstract This paper describes a compiler‐based approach to checkpointing for process recovery. The implementation is transparent to both the programmer and the hardware. The compiler‐generated sparse potential checkpoint code maintains the desired checkpoint interval. Adaptive checkpointing reduces the size of the checkpoints. Training is used to select low‐cost, high‐coverage potential checkpoints. The problem of selecting potential checkpoints is shown to be NP‐complete, and a heuristic algorithm is introduced that determines a quick suboptimal solution. These compiler‐assisted checkpointing techniques have been implemented in a modified version of the GNU C (GCC) compiler. Experiments involving the modified version of the GCC compiler on a Sun SPARC workstation are summarized.
Optically pumped atmospheric-pressure CO2 laser (1972)

Laser action at 10.6 μm has been obtained in pure CO2 gas at pressures up to 1 atm by optically pumping with the 4.23μm line of a TEA HBr laser. The potential usefulness of this method for pumping very high density CO2 is discussed.
