Locomotor capacities after complete and partial lesions of the spinal cord (1996)

This paper first reviews some of the observations made on the locomotor capabilities of several animal species with a special emphasis on cats and including primates and man after complete spinal lesions. We show that animals can perform well-coordinated walking movements of the hindlimbs when they are placed on a treadmill belt and this locomotion is also adaptable to speed and perturbations. Cats with partial spinal lesions of the ventral and ventrolateral parts of the cord can perform voluntary quadrupedal locomotion overground or on the treadmill albeit with deficits in weight support and interlimb coordination. We also show that some drugs such as clonidine (an alpha-2 noradrenergic agonist) can be used to trigger locomotion in early-spinal cats and discuss the effects of various neurotransmitter systems on the expression of the locomotor pattern in both complete and partial spinal cats. It is concluded that a pharmacological approach could be used, in combination with other approaches, such as locomotor training and functional electrical stimulation, to improve locomotor functions after spinal cord injuries in humans.
Directing Colloidal Self-Assembly through Roughness-Controlled Depletion Attractions (2007)

The surfaces of colloidal particles resulting from many new fabrication methods are not molecularly smooth, so understanding how surface roughness can affect the depletion attraction between the particles and their assembly is very important. We show that the depletion attraction between custom-shaped microscale platelets can be suppressed when the nanoscale surface asperity heights become larger than the depletion agent. In the opposite limit, the attraction reappears and columnar stacks of platelets are formed. Exploiting this, we selectively increase the site-specific roughness on only one side of the platelets to direct the mass production of a single desired assembly: a pure dimer phase.

Zeolite-Containing Co Catalysts for Fischer–Tropsch Synthesis with Tailor-Made Molecular-Weight Distribution of Hydrocarbons (2023)

The review is dedicated to the topical field of research aimed at creating catalysts combining several types of active sites. At the same time, the composition of Fischer–Tropsch synthesis (FTS) products can be controlled by changing the strength and concentration of the active sites and inter-site distances. A comparative analysis of the literature data allows to formulate the main principles of catalytic particles formation active in FTS and acid-catalyzed transformations of hydrocarbons: (1) the presence of weak Bronsted acid sites to control the cracking depth, (2) an availability of Bronsted acid sites for re-adsorption hydrocarbons and (3) weak Co-zeolite interaction to reduce methane formation.
Multi-label Classification of Electrocardiogram With Modified Residual Networks (2020)

In this study, an end-to-end deep residual neural network with one dimensional convolution is presented to identify the 12-lead ECGs for the PhysioNet/Computing in Cardiology Challenge 2020 with different durations and sampling frequency. Firstly, a split attention block that enables attention across feature-map groups is introduced to the modified residual networks based on one dimensional convolutional neural network. Secondly, referring to the improved residual network (iResNet), the modified network architecture for residual learning based on stages is present to provide a better path for information to propagate through network's layers. Moreover, an improved projection shortcut that reduces the information loss is proposed in our proposed modified residual network. Finally, fine-tune is adopted through pre-trained model, which avoids training the network from scratch and virtually expands the dataset and enhances the generalization performance.
Declarative Question Answering over Knowledge Bases containing Natural\n Language Text with Answer Set Programming (2019)

While in recent years machine learning (ML) based approaches have been the\npopular approach in developing end-to-end question answering systems, such\nsystems often struggle when additional knowledge is needed to correctly answer\nthe questions. Proposed alternatives involve translating the question and the\nnatural language text to a logical representation and then use logical\nreasoning. However, this alternative falters when the size of the text gets\nbigger. To address this we propose an approach that does logical reasoning over\npremises written in natural language text. The proposed method uses recent\nfeatures of Answer Set Programming (ASP) to call external NLP modules (which\nmay be based on ML) which perform simple textual entailment. To test our\napproach we develop a corpus based on the life cycle questions and showed that\nOur system achieves up to $18\\%$ performance gain when compared to standard MCQ\nsolvers.\n
Common Sense in Formation for the Common Good--Justice White's Dissents in the Parochial School Aid Cases: Patron of Lost Causes or Precursor of Good News (2012)

This Article envisions a new order for public education in this country. Pursuant to the new order, a free market under appropriate government regulation rather than unchecked political authority would determine the flow of public aid to various schools. Such an order would enable parents to choose what kind of school, secular or sectarian, presents the most desirable educational environment. The new arrangement would also provide incentives for quality education, as schools now run by the state government would have to compete on an even field with schools that currently receive no public funds. It has been almost twenty years since Justice White first expressed the view that the Supreme Court's invalidation of parochial school aid "was not required by the First Amendment and is contrary to the long range interests of the country." The historical evidence now suggests the need for a substantial revision of the Court's approach to the meaning of the religion clauses. Not only should the new approach adopt a less formalistic doctrine that allows consideration of the secular merits of parochial schools, but it needs also to appreciate the theological anthropology and free-exercise concerns that inspired the adoption of the religion clauses. While a fresh approach is desirable on the basis of the revised understanding of the First Amendment's meaning, more pressing and urgent public policy considerations demand it. The concrete social reality is that the parochial schools are serving as the sole guarantors of several constitutional rights for a significant number of low- and middle-income families. In the absence of the parochial schools, the Fourteenth Amendment's promise of equal protection and due process as well as the First Amendment's free exercise guarantee run the risk of being reduced to mere rhetoric. To the extent that it fails to consider both the true meaning of the First Amendment and the long-range interests of the country, the Supreme Court's constitutional theory amounts to a flight from reality. Through the medium of dissent, Justice White has challenged the Court to abrogate the argument based on historical authority and to entertain the compelling public policy justifications in support of parochial school aid. He has left open the possibility that parochial schools will not be added to the list of defunct subsidiary institutions. One can only hope that he may soon be recognized as a herald of good news.
Steuerung von Blechmassivumformprozessen durch maßgeschneiderte tribologische Systeme (2019)

Steigende Anforderungen in der Industrie beispielsweise in Hinblick auf verkürzte Prozessketten, eine erhöhte Funktionsintegration oder ökologische Aspekte führen dazu, dass die konventionellen Verfahren der Blech- und Massivumformung an ihre Grenzen stoßen. Ein Lösungsansatz zur Erweiterung der Prozessgrenzen ist die Kombination beider Verfahrensklassen in der sogenannten Blechmassivumformung. Eine derartige Kombination resultiert in einem simultanen Auftreten von Bedingungen aus der Blech- und der Massivumformung. Dies führt wiederum zu einem unkontrollierten Stofffluss und einer reduzierten Bauteilqualität. Im Rahmen der Arbeit wurden globale Stoffflusssteuerungsmethoden über eine lokale Einstellung der tribologischen Bedingungen erforscht und im Hinblick auf ihre Wirksamkeit verifiziert. Um dies zu realisieren, wurden die tribologischen Wirkmechanismen der modifizierten Werkzeug- und Werkstückoberflächen identifiziert, um unabhängig vom in der Arbeit untersuchten Parameterraum, den Einsatz der Methoden für die Blechmassivumformung zu ermöglichen.
Toward an augmented shoe for preventing falls related to physical conditions of the soil (2012)

It is known that the physical conditions of an environment might represent an important risk of falling. In this paper, we report an ongoing project toward the creation of intelligent clothes aiming at preventing falls related to such conditions. The package described here is centered on an intelligent shoe. The developed prototype counts two main parts: hardware and software. The material is composed of a set of sensors and actuators, distributed in strategic positions of the shoe, while the software is a soft real-time system running on a Smartphone. Our prototype has been served for the differentiation of physical properties of soils (concrete, broken stone, sand and dust stone).
Electro-optic E-field sensors for shielding measurements up to 18 GHz (2002)

Two small intrinsically optical electric field sensors suitable for making shielding effectiveness measurements of small enclosures over the frequency ranges 50 MHz to 2 GHz and 2 to 18 GHz have been developed. Each sensor is based around a Mach-Zehnder optical modulator with a miniature antenna used as a sensing element. Fields as low as 0.1 m V m(-1) can be measured in the lower of the two frequency ranges with a dynamic range of 100 dB available for shielding measurements. Optical field sensors have been reported before, but not with the sensitivity described here, or the ability to operate up to 18 GHz. In addition, the sensors are made mainly with "off-the-shelf" components.
Abstract B28: Selective antagonism of IAP proteins for regulating apoptosis and TNF pathways (2009)

Abstract The inhibitor of apoptosis (IAP) proteins are important regulators of cancer cell survival, making them important targets for oncological intervention. There are eight known members of the IAP family of proteins. Using a combination of structure-based design and a merger of existing inhibitor motifs, we generated selective inhibitors that will interrogate the biological relevance of antagonism of XIAP and c-IAP1 and 2. The cellular biology of selective antagonism of these proteins will be presented. Citation Information: Mol Cancer Ther 2009;8(12 Suppl):B28.
Spatial Differentiation in the Vegetative Mycelium of Aspergillus niger (2007)

Fungal mycelia are exposed to heterogenic substrates. The substrate in the central part of the colony has been (partly) degraded, whereas it is still unexplored at the periphery of the mycelium. We here assessed whether substrate heterogeneity is a main determinant of spatial gene expression in colonies of Aspergillus niger. This question was addressed by analyzing whole-genome gene expression in five concentric zones of 7-day-old maltose- and xylose-grown colonies. Expression profiles at the periphery and the center were clearly different. More than 25% of the active genes showed twofold differences in expression between the inner and outermost zones of the colony. Moreover, 9% of the genes were expressed in only one of the five concentric zones, showing that a considerable part of the genome is active in a restricted part of the colony only. Statistical analysis of expression profiles of colonies that had either been or not been transferred to fresh xylose-containing medium showed that differential expression in a colony is due to the heterogeneity of the medium (e.g., genes involved in secretion, genes encoding proteases, and genes involved in xylose metabolism) as well as to medium-independent mechanisms (e.g., genes involved in nitrate metabolism and genes involved in cell wall synthesis and modification). Thus, we conclude that the mycelia of 7-day-old colonies of A. niger are highly differentiated. This conclusion is also indicated by the fact that distinct zones of the colony grow and secrete proteins, even after transfer to fresh medium.
A Moisture-in-Oil Model for Power Transformer Monitoring—Part II: Experimental Verification (2005)

For Part I see ibid., p.1417-22, 2005. In the companion paper, a model to detect failures leading to an increase of the water content in transformer oil was proposed. In this paper, the experimental verification of the model is presented. The model was tested in a 1500-kVA test transformer constructed as a reduced scale model of a 60-MVA 220-kV transformer. In order to load the transformer to have the capability of varying load and power factor over a wide range, the opposition method described in IEC 60076-2 Standard was used. Sensors to measure temperature and moisture in oil were installed in the test transformer. The model was adjusted and validated using a set of data corresponding to different operating conditions. The transformer was submitted to an accelerated aging process studying the model response in such a case. In order to verify the model's ability to detect failures, a water ingress in the transformer was simulated.
Identification of Ultrasound Echoes from the Left Ventricle by Use of Intracardiac Injections of Indocyanine Green (1970)

This study was designed to identify the ultrasound echoes originating from the left ventricle. Injections of indocyanine green and saline were made directly in the left ventricular cavity via a cardiac catheter in patients undergoing routine diagnostic cardiac catheterization. The injections produced a cloud of echoes that filled the left ventricular cavity and outlined the left side of the interventricular septum and the endocardial surface of the posterior left ventricular wall. The results of this study verified the origin of echoes that are vital to the ultrasound technics for the detection of pericardial effusion, left ventricular wall size, left ventricular cavity size, and left ventricular stroke volume. This study also provided ways of distinguishing between the true left ventricular wall echoes and intracavitary echoes that often cause confusion.
DRUG-INDUCED HYPERPROLACTINAEMIA AND DISCHARGES OF LUTEINIZING HORMONE EVOKED BY OESTROGEN IN OVARIECTOMIZED RHESUS MONKEYS (1982)

Ovulatory failure associated with hyperprolactinaemia has been attributed to the inability of oestrogen to evoke a preovulatory discharge of gonadotrophins. This hypothesis was tested in ovariectomized rhesus monkeys rendered hyperprolactinaemic by treatment with two dopamine antagonists, domperidone, a compound reported not to cross the blood-brain barrier in rats, and sulpiride, a drug with known actions on both pituitary and central dopaminergic receptors. An artificial surge of oestrogen similar to that observed at mid-cycle in intact monkeys was obtained with subcutaneous capsules filled with oestradiol-17 beta. Treatment with either drug increased prolactin concentrations to 1.0 i.u./l or more compared with control values of 0.1-0.3 i.u./1. In the presence of these greatly increased prolactin levels, a normal discharge of LH, indistinguishable from that observed in control animals, was provoked by oestrogens in all but one drug-treated monkey. Furthermore, neither the basal (pre-oestrogen) level of LH nor the negative feedback action of oestrogen was consistently altered in hyperprolactinaemic monkeys. Administration of progesterone or 17 alpha-hydroxyprogesterone to simulate more closely the conditions observed in intact animals during the periovulatory period did not alter the LH discharge induced by oestrogen in animals treated with domperidone. The present results suggest that the high levels of prolactin brought about by dopaminergic blockade do not affect the positive feedback action of oestrogen. Furthermore, low levels of progestins do not sensitize the hypothalamic-pituitary axis towards an inhibitory action of prolactin on oestrogen-induced LH release. The rhesus monkey thus differs from other species, including man, in which artificially induced hyperprolactinaemia may impair or abolish the positive feedback action of oestrogen.
Structural and Electrical Properties of Flash-Evaporated Thin GaAs Films (1969)

A flash-evaporation scheme modified to control the rate of the powder fed to the evaporator was used for depositing GaAs films on amorphous glass substrates. A bulk wurtzite form of GaAs was identified with x-ray diffraction and found to have an axial ratio of 1.684. Periodic faulting induced by the plunger movement of the powder feeder is believed to cause the formation of this phase. Structural analysis of the flash evaporated films was performed using a Fourier line broadening analysis and integral breadth measurements. A least-squares approximation of the ``Warren-Averbach'' method yielded particle sizes of 125 Å and rms microstrains of 0.0018. The films were doped during growth with germanium, indium and tin. Germanium doping produced p-type films while both indium and tin doping produced n-type. Mobilities greater than 0.5 cm2/V·sec were found for a narrow range of doping (1018−1019/cm3) for the tin doped films. The films grown with no auxiliary dopant were p-type with carrier concentrations exceeding 1019/cm3 and mobilities near 0.01 cm2/V·sec.
Acute Graft-Versus-Host Disease, Infections, Vascular Events and Drug Toxicities Affecting the Central Nervous System (2021)

Allogeneic hematopoietic cell transplantation (allo-HCT) is a curative therapy for patients with hematological malignancies. Acute Graft <i>versus</i> host diseases (GVHD) is a major immune mediated side effect of allo-HCT that can affect the central nervous system (CNS) in addition to post-allo-HCT vascular events, drug toxicity or infections. Here we summarize and discuss recent preclinical data on the CNS as a target of acute GVHD and the known mechanisms contributing to neurotoxicity with a focus on microglia and T cells. We also discuss open questions in the field and place the findings made in mouse models in a clinical context. While in mice the neurological deficits can be assessed in a controlled fashion, in patients the etiology of the CNS damage is difficult to attribute to acute GVHD <i>versus</i> infections, vascular events, and drug-induced toxicity. Ultimately, we discuss novel therapies for GVHD of the CNS. Our understanding of the biological mechanisms that lead to neurotoxicity after allo-HCT increased over the last decade. This review provides insights into CNS manifestations of GVHD <i>versus</i> other etiologies of CNS damage in mice and patients.
Experimental Implementation and Capabilities of Fourier Transform Hydrodynamic Modulation Voltammetry (1993)

Reported is the first experimental implementation of Fourier transform hydrodynamic modulation voltammetry (FTHMV). Two different types of experiments are performed to illustrate the capabilities of the technique. First, the analytical utility of FTHMV is demonstrated by applying the technique to study the frequency response characteristics of mass‐transfer limited reduction of 2 mM ferric ion at a speed‐modulated rotating disk electrode. It is shown that FTHMV, performed using a square wave rotation rate modulation, is a fast and accurate method for characterizing the system's frequency response in a single experiment, and thus provides an excellent alternative to the common practice of performing many experiments one frequency at a time. The second application of FTHMV reported here is the analysis of nonlinearities in the mass‐transfer limited current to a rotating disk electrode modulated at a single frequency. We show that the magnitude of nonlinear harmonics induced by a sinusoidal rotation rate modulation has a power law form, where the nonlinear signal is proportional to the amplitude of the rotation rate modulation raised to the power of the harmonic component. Also discussed are the implications of time domain signal processing for improving the signal‐to‐noise performance of FTHMV.
Physical experiment and computer simulation of the speed-up manoeuvre using the absolute nodal coordinate formulation (2017)

This paper presents an experimental validation of the absolute nodal coordinate formulation spatial element with the speed-up manoeuvre. A long, thin steel beam with a circular cross-section is analysed. The beam is fixed at the middle with the clamp that itself is attached to the brushless motor housing. The drive is controlled by a dedicated speed controller and the final speed is set by adjusting the PWM signal level. The position of specific points at the beam and the drive is measured by attached markers with a high-speed camera that records the picture with 2400 frames per second. The position of the rotor is then used as input for further multibody dynamic analysis. The top rotational speed of the rotor is far larger than the critical speed for the linear floating frame of reference model. The beam is modelled with a continuum-based, standard, curved, two-node absolute nodal coordinate formulation beam element. As Poisson locking often occurs in thin absolute nodal coordinate formulation beams, selective reduced integration is employed to alleviate the locking influence. The air drag is modelled with a simple model of idealised air flow around the cylinder. A comparison of the experimental and the computer simulation reveals a good agreement between the results.
A Survey on Various Edge Detector Techniques (2012)

Edge detection is the first step in many computer vision applications. Edge detection significantly reduces the amount of data and filters out unwanted or insignificant information and gives the significant information in an image. These information are used in image processing to detect objects. There are some problems like false edge detection, problems due to noise, missing of low contrast boundaries etc. This paper presents a comparison between various edge detectors to identify which edge detector performs better results. The software is developed using MATLAB. It has been shown that modified declivity operator gives better result as compared to other edge detectors.
