Document Page Decomposition by the Bounding-Box Projection Technique (1995)

This paper describes a method for extracting words, textlines and text blocks by analyzing the spatial con-figuration of bounding boxes of connected components on a given document image. The basic idea is that connected components of black pixels can be used as computational units in document image analysis. In this paper, the problem of extracting words, textlines and text blocks is viewed as a clustering problem in the &amp;dimensional discrete domain. Our main strategy is that profiling analysis is utilized to measure horizontal or vertical gaps of (groups of) components during the process of image segmentation. For this purpose, we compute the smallest rectangular box, called the bound-ing box, which circumscribes a connected component. Those boxes are projected horizontally and/or verti-cally, and local and global projection profiles are an-alyzed for word, textline and text-block segmentation. In the last step of segmentation, the document decom-position hierarchy is produced from these segmented objects. 1
A Multigate Pulsed Doppler System with Serial Data Processing (1981)

Abstruct-Multigate pulsed Doppler systemsenable the transcutaneous and simultaneous assessment of the velocities in a number of adjacent sample volumes as a continuous function of time. Since the velocity distribution along the ultrasonic beam is readily available, detailed information can be obtained about the time-dependent flow behavior in the major superficial arteries. A multigate pulsed Doppler system processing the information originating from 32 sample volumes in a sequential way ispresented. Serial data processingis achieved by digitizing the range and time-dependent phase signal and performing the required signal processing (filtering and zero crossing counting) in a digital form. The multigate system is connected to a storage unit, enabling online visualization of the recorded velocity profiles over a number of cardiac cycles. Two output modes are available: the velocity distribution as a continuous function of depth at discrete time intervals and the velocities in a number of adjacent sample volumes as a continuous function of time. The number of interactive controls is restricted to only two: the selector of the sample volume for audio output and the HALT command for the digital storage unit. Both controls can be operated by a footswitch, allowing maximal mobility for the investigator. Resenfly the increasing noise level with increasing depth limits the useful exploration range to 45 mm.
High-temperature stable gratings in germanosilicate planar waveguides (1998)

Negative index gratings in planar germanosilicate waveguides were found to be stable up to 500 degrees C. The annealing properties are similar to those of negative index fiber gratings.
Surgical Treatment of the Difficult Humeral Neck Fracture (1980)

A surgical approach to the shoulder joint for the difficult humeral neck fracture is described with illustration of a case. Resection of a middle portion of the acromial process in addition to the detachment of the anterior origin of the deltoid using an anterolateral approach is presented. This provides an unrestricted exposure to the shoulder joint and eliminates the possible complications arising from acromionectomy.
Effect of CMV serology on outcome after clinical intestinal transplantation. (1996)

OVER the last 5 years, intestinal transplantation has become a feasible therapeutic option for patients with irreversible intestinal failure.1 Cytomegalovirus (CMV) infection was shown to be the most frequent viral infection in the intestinal transplant recipients and to be related to high mortality and morbidity.2,3 In this study, we analyzed the effect of CMV serology of donors and recipients on the outcome of patient and graft survival after intestinal transplantation.

p120 catenin is required for morphogenetic movements involved in the formation of the eyes and the craniofacial skeleton in <i>Xenopus</i> (2004)

During Xenopus development, p120 transcripts are enriched in highly morphogenetic tissues. We addressed the developmental function of p120 by knockdown experiments and by expressing E-cadherin mutants unable to bind p120. This resulted in defective eye formation and provoked malformations in the craniofacial cartilage structures, derivatives of the cranial neural crest cells. Closer inspection showed that p120 depletion impaired evagination of the optic vesicles and migration of cranial neural crest cells from the neural tube into the branchial arches. These morphogenetic processes were also affected by p120-uncoupled cadherins or E-cadherin containing a deletion of the juxtamembrane domain. Irrespective of the manipulation that caused the malformations, coexpression of dominant-negative forms of either Rac1 or LIM kinase rescued the phenotypes. Wild-type RhoA and constitutively active Rho kinase caused partial rescue. Our results indicate that, in contrast to invertebrates, p120 is an essential factor for vertebrate development and an adequate balance between cadherin activity and cytoskeletal condition is critical for correct morphogenetic movements.
Towards Mitochondrial Gene Therapy: DQAsomes as a Strategy (2001)

Mitochondrial dysfunction is a cause, or major contributing factor in the development, of degenerative diseases, aging, cancer, many cases of Alzheimer's and Parkinson's disease and Type II diabetes (D. C. Wallace, Science 283, 1482-1488, 1999). Despite major advances in understanding mtDNA defects at the genetic and biochemical level, there is no satisfactory treatment for the vast majority of patients available. Objective limitations of conventional biochemical treatment for patients with defects of mtDNA warrant the exploration of gene therapeutic approaches. However, mitochondrial gene therapy has been elusive, due to the lack of any mitochondria-specific transfection vector. We review here the current state of the development of mitochondrial DNA delivery systems. In particular, we are summarizing our own efforts in exploring the mitochondriotropic properties of dequalinium, a cationic bolaamphiphile with delocalized charge centers, for the design of a vector suited for the transport of DNA to mitochondria in living cells.
A FINITE ELEMENT MODEL OF IN VIVO MOUSE TIBIAL COMPRESSION LOADING: INFLUENCE OF BOUNDARY CONDITIONS UDC (531.2+519.6):617.3 (2014)

Though bone is known to adapt to its mechanical challenges, the relationship between the local mechanical stimuli and the adaptive tissue response seems so far unclear. A major challenge appears to be a proper characterization of the local mechanical stimuli of the bones (e.g. strains). The finite element modeling is a powerful tool to characterize these mechanical stimuli not only on the bone surface but across the tissue. However, generating a predictive finite element model of biological tissue strains (e.g., physiological-like loading) encounters aspects that are inevitably unclear or vague and thus might significantly influence the predicted findings. We aimed at investigating the influence of variations in bone alignment, joint contact surfaces and displacement constraints on the predicted strains in an in vivo mouse tibial compression experiment. We found that the general strain state within the mouse tibia under compressive loading was not affected by these uncertain factors. However, strain magnitudes at various tibial regions were highly influenced by specific modeling assumptions. The displacement constraints to control the joint contact sites appeared to be the most influential factor on the predicted strains in the mouse tibia. Strains could vary up to 150% by modifying the displacement constraints. To a lesser degree, bone misalignment (from 0 to 20°) also resulted in a change of strain (+300 µe = 40%). The definition of joint contact surfaces could lead to up to 6% variation. Our findings demonstrate the relevance of the specific boundary conditions in the in vivo mouse tibia loading experiment for the prediction of local mechanical strain values using finite element modeling.
Theory of the emission of long-wave light quanta (1994)

Nuovo Cimento, 15, 167–88. Presented at the Galvani Bicentenary Congress, Bologna, 18–21 October 1937.Summary – As is well known, the usual radiation theory yields an infinitely large value (infrared catastrophe) for the cross section dq of a charged particle when it traverses a force field and is deflected at a given angle. For if one prescribes that the energy loss of the particle should lie between E and E + dE, then, according to this theory, for small E one obtains dq = const. dE/E, which, upon integration, diverges logarithmically at the point E = 0. The present paper investigates more precisely what quantum electrodynamics yields for this cross section if a finite extent is ascribed to the charged body. It appears that then the infinity is indeed removed and that the deflections which are considered as nonradiative in the ordinary theory here appear as having a finite, although very small, energy loss. On the other hand, according to the exact theory, the more precise behavior of dq for very small energy losses E depends so strongly on the extension of the charged body, that a direct application of the result to real electrons is not possible. Therefore, one must conclude that the problem in question is related in an essential manner to the still unresolved fundamental difficulties of quantum electrodynamics.
Sensory rhodopsinlike proteins in Halobacterium halobium. (1986)

Recently, a third retinal binding chromoprotein was found in cell membrane of Halobacterium halobium. Like bacteriorhodopsin and halorhodopsin, the third pigment shows photoreaction cycling upon illumination, but the decay of its photointermediate is two orders of magnitude slower than that of the two. Behavioral studies have shown that the pigment acts as photoreceptors for both positive and negative phototactic systems in this bacteria. Also, another photorepellent system has been found in the course of the study, which is mediated by a different (the fourth) photoreactive retinal-protein pigment.
Anti‐HBc of IgM‐class, HBeAg and anti‐HBe in acute and chronic hepatitis B (1981)

The presence and persistence of IgM antibody against hepatitis B core antigen (anti-HBc IgM) and the correlation with other HBV markers were studied in 42 patients, all of whom had acute HBsAg-positive hepatitis but whose subsequent diseases differed. All patients initially had anti-HBc IgM. In 13 out of 15 patients with uncomplicated acute hepatitis, anti-HBc IgM disappeared within 6 months after onset of the disease. In five out of 12 patients, who in spite of transient HBsAg developed chronic liver disease, the anti-HBc IgM persisted for more than 2 years. Among 15 patients with persistent HBsAg, anti-HBc IgM was present from 7 months to more than 8 years. Seroconversion from HBeAg to anti-HBe was observed in seven patients and in five of these anti-HBc IgM disappeared during the follow-up period. These results indicate that anti-HBc IgM can be used as a serological marker of recent or ongoing HBV infection.
Computer power systems: the burn-in dilemma (1986)

The computer manufacturer faces a dilemma in that power system burn-in is a significant component of product cost and needs to be eliminated to meet increasing price competition, but quality and reliability must not be sacrificed in pursuit of this goal. This paper discusses our experience with this problem.

Acute transverse myelitis in systemic lupus erythematosus: magnetic resonance imaging and review of the literature. (1990)

We describe a patient with systemic lupus erythematosus (SLE) who presented with acute transverse myelitis. Magnetic resonance imaging (MRI) of the cervical spine demonstrated increased signal intensity and diffuse edema in the cervical cord. The patient had low titer of IgG antiphospholipid antibodies and hypocomplementemia. Cerebrospinal fluid analysis showed pleocytosis, increased protein and decreased glucose. Clinical improvement of the neurologic impairment was noted after high dose corticosteroids and intravenous bolus cyclophosphamide. A repeat MRI 12 days after the treatment was normal. MRI of the spine can be useful in the diagnosis and followup of patients with SLE presenting with an acute myelopathic syndrome. Early aggressive treatment may contribute to complete recovery of these patients.
Effects of time domain response on sonic characteristics of microphones (1998)

Among practitioners of the recording arts, a correlation is popularly deemed to exist between aspects of a microphone’s time domain response and its subjective qualities. This eperiment sought to reveal such correlations using appropriate measurement and statistical procedures. Impulse response tests were performed on a set of 12 microphones using both electric spark and maximum length sequence methods. Cumulative spectral decay waterfall plots were then carefully examined for unusual behavior which led to objective feature extraction. Feature-specific quantitative data were then mathematically scaled from both the impulse response and cumulative spectral decay plots to form the objective parameter base. Three musical examples were recorded at each of two proximities with each microphone, and subjective listening tests were performed on these recordings in a controlled environment using expert listeners. The recorded examples included 8 of the 12 microphones and were evaluated for three subjective qualities, namely warmth, brightness, and depth, which provided the subjective parameter base. The data from the objective and subjective tests were statistically analyzed using N-dimensional replacement [M. H. Moulton, U. of Chicago (1996)]. Complete experimental procedure, results, and implications will be presented.
A posteriori corrections to the Iterative Qubit Coupled Cluster method\n to minimize the use of quantum resources in large-scale calculations (2020)

The iterative qubit coupled cluster (iQCC) method is a systematic variational\napproach to solve the electronic structure problem on universal quantum\ncomputers. It is able to use arbitrarily shallow quantum circuits at expense of\niterative canonical transformation of the Hamiltonian and rebuilding a circuit.\nHere we present a variety of a posteriori corrections to the iQCC energies to\nreduce the number of iterations to achieve the desired accuracy. Our energy\ncorrections are based on a low-order perturbation theory series that can be\nefficiently evaluated on a classical computer. Moreover, capturing a part of\nthe total energy perturbatively, allows us to formulate the qubit active-space\nconcept, in which only a subset of all qubits is treated variationally. As a\nresult, further reduction of quantum resource requirements is achieved. We\ndemonstrate the utility and efficiency of our approach numerically on the\nexamples of 10-qubit N$_2$ molecule dissociation, the 24-qubit H$_2$O symmetric\nstretch, and 56-qubit singlet-triplet gap calculations for the technologically\nimportant complex, tris-(2-phenylpyridine)iridium(III), Ir(ppy)$_3$.\n
Effects of Stabilizer Thickness of 2G HTS Wire on the Design of a 1.5-MW-Class HTS Synchronous Machine (2016)

In general, a metallic stabilization layer is overcoated on the outermost layer of a second-generation high-temperature superconducting (2G HTS) wire to stably transfer current against thermal and magnetic disturbances. Stabilizer thickness <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$T_{{s}}$</tex-math></inline-formula> is one of the key issues in an HTS synchronous machine (HTSSM) application because it strongly affects the electrical output performance of the machine and the stable operation and reliable protection of the HTS field coil. In this paper, a design and characteristic analysis for manufacturing a 1.5-MW-class HTSSM was performed using a 2-D analytical design code and a 3-D finite-element method. Various <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$T_{{s}}$</tex-math></inline-formula> values were considered in the HTS field-coil design to investigate their effects on the stability and protection of the HTS coil and the back-electromotive force of the machine.

The central hypotensive action of amphetamine, ephedrine, phentermine, chlorphentermine and fenfluramine (1972)

Abstract The influence of amphetamine, ephedrine, phentermine, chlorphentermine and fenfluramine on blood pressure after infusion into the vertebral artery was studied in anaesthetized cats. All drugs lowered blood pressure after infusion into the vertebral artery but showed hypertensive properties upon intravenous administration in the same dosage, although chlorphentermine (i.v.) decreased pressure after a minor initial rise. The hypotensive action of amphetamine was blocked by piperoxan or yohimbine (α-adrenoceptor blocking agents) and by haloperidol which is known to block central adrenoceptors. The hypotensive action of amphetamine was abolished in reserpinized cats and usually a small increase in blood pressure was observed in these animals after infusion of amphetamine in the vertebral artery. The hypotensive action of amphetamine is probably due to the mobilization of noradrenaline in the brain. The results suggest that the drugs show central hypotensive properties probably brought about by stimulation of central α-adrenoceptors, thus causing a decrease in peripheral sympathetic tone. This general principle would also explain the central hypotensive properties of α-methyl- dopa, α-methylnoradrenaline, l-dopa and m-tyrosine.
Structure and Properties of Endosperm Starch and Water Soluble Polysaccharides from Sugary Mutant of Rice (<i>Oryza sativa</i> L.) (1985)

Abstract Structure and properties of starch and water soluble polysaccharides (WSP) from sugary ( su ) endosperm of rice were examined. The su starch contained more amylose and had a somewhat higher ratio of the short chains to the long chains of amylopectin than normal starch. The WSP consisted of short α‐1, 4‐chains and their average degree of polymerization was 8.6 glucose units. Susceptibility of the su starch to crude Rh . glucoamylase was higher than that of the normal. The initial and final temperatures and heat of gelatinization of the su starch granules were much lower than those of the normal ones.
Molecular Epidemiology of Human Astroviruses (2001)

Human astroviruses (HAstVs) are associated with 5-9 percent of cases of gastroenteritis in young children. Seven serotypes (HAstV-1 to -7), which correlate with genotypes, have been defined by using immune typing methods. We have used partial nucleotide sequence information from the capsid protein gene for molecular typing of 29 unique human astrovirus strains obtained from prospective studies of children with gastroenteritis in Egypt and Malawi. HAstV-1 was the most commonly detected strain, consistent with previous studies, but a surprising variety of strains were identified in both collections. An eighth astrovirus type, HAstV-8, has been defined on the basis of the complete capsid protein gene sequence and was detected in both collections analysed in this study. Although HAstV-8 and HAstV-4 strains segregate into well resolved clades by analysis of sequences from the region encoding protein P2 (VP32), the pair-wise distances between these types are less than those between strains of the other serotypes. In contrast, analysis of sequences from the region encoding protein P3 unambiguously resolve HAstV-4 and HAstV-8 strains, consistent with their classification as distinct serotypes. Overall, strains representing six of the eight serotypes were detected in two collections of samples from prospective studies of gastroenteritis in young children indicating that multiple astrovirus types are frequently co-circulating within communities.
