Regeneration of optical signals by fiber logic elements operating through stimulated Raman scattering and development of fiber optic memory (1993)

For the first time an all-optical fiber recirculating loop memory with a long storage time is demonstrated experimentally. Information is stored in the memory by recirculating optical pulses through a closed fiber loop employing all-optical repeaters operating via the stimulated Raman scattering (SRS) effect. The time during which information storage was observed was 10 min. The number of round trips through the loop was more than 100 million.
The feasibility and outcome of nephron‐sparing surgery for children with bilateral Wilms tumor (2008)

All patients who had bilateral Wilms tumors with favorable histology, except for 1 patient who had extensive tumor thrombus, underwent successful bilateral partial nephrectomies. Complications were minimal, and long-term renal function and survival were excellent. From this experience, the authors concluded that bilateral nephron-sparing surgery should be considered for all patients who have bilateral Wilms tumor with favorable histology, even if preoperative imaging studies suggest that the lesions are unresectable.
Proteomic Analysis of Exosomes from Human Neural Stem Cells by Flow Field-Flow Fractionation and Nanoflow Liquid Chromatography−Tandem Mass Spectrometry (2008)

Exosomes, small membrane vesicles secreted by a multitude of cell types, are involved in a wide range of physiological roles such as intercellular communication, membrane exchange between cells, and degradation as an alternative to lysosomes. Because of the small size of exosomes (30-100 nm) and the limitations of common separation procedures including ultracentrifugation and flow cytometry, size-based fractionation of exosomes has been challenging. In this study, we used flow field-flow fractionation (FlFFF) to fractionate exosomes according to differences in hydrodynamic diameter. The exosome fractions collected from FlFFF runs were examined by transmission electron microscopy (TEM) to morphologically confirm their identification as exosomes. Exosomal lysates of each fraction were digested and analyzed using nanoflow LC-ESI-MS-MS for protein identification. FIFFF, coupled with mass spectrometry, allows nanoscale size-based fractionation of exosomes and is more applicable to primary cells and stem cells since it requires much less starting material than conventional gel-based separation, in-gel digestion and the MS-MS method.
Supervising Communication SoC for Secure Operation Using Machine Learning (2019)

Manufacturers normally buy and/or fabricate communication chips using third-party suppliers, which are then integrated into a complex hardware-software stack with a variety of potential vulnerabilities. This work proposes a compact supervisory circuit to classify the operation of a Bluetooth (BT) SoC at low frequencies by monitoring the input power and radio frequency (RF) output of the BT chip passed through an envelope detector. The idea is to inexpensively fabricate an envelope detector, power supply current monitor, and classification algorithm on a custom low-frequency integrated circuit in a trusted legacy technology. When the supervisory circuit detects unexpected behavior, it can shut off power to the BT SoC. In this preliminary work, we proto-type the supervisory circuit using off-the-shelf components. We extract simple yet descriptive features from the envelope of the RF output signal. Then, we train machine learning (ML) models to classify different BT operation modes, such as BT advertising and transmit modes. Our results show ~100% classification accuracy.
Effects of Gut Metabolites and Microbiota in Healthy and Marginal Livers Submitted to Surgery (2020)

Microbiota is defined as the collection of microorganisms within the gastrointestinal ecosystem. These microbes are strongly implicated in the stimulation of immune responses. An unbalanced microbiota, termed dysbiosis, is related to the development of several liver diseases. The bidirectional relationship between the gut, its microbiota and the liver is referred to as the gut-liver axis. The translocation of bacterial products from the intestine to the liver induces inflammation in different cell types such as Kupffer cells, and a fibrotic response in hepatic stellate cells, resulting in deleterious effects on hepatocytes. Moreover, ischemia-reperfusion injury, a consequence of liver surgery, alters the microbiota profile, affecting inflammation, the immune response and even liver regeneration. Microbiota also seems to play an important role in post-operative outcomes (i.e., liver transplantation or liver resection). Nonetheless, studies to determine changes in the gut microbial populations produced during and after surgery, and affecting liver function and regeneration are scarce. In the present review we analyze and discuss the preclinical and clinical studies reported in the literature focused on the evaluation of alterations in microbiota and its products as well as their effects on post-operative outcomes in hepatic surgery.
&lt;title&gt;Single-exposure wide-wavelength-coverage echelle spectrograph&lt;/title&gt; (1995)

We present the design for an echelle spectrograph for 6.5 m telescopes: i.e. the converted MMT and Magellan. We incorporate fused silica prism cross dispersion for higher transmission, and use a single camera that records simultaneously full 300 - 1100 nm wavelength range of CCD detectors. The broad wavelength coverage in a single exposure will make this a powerful instrument for many scientific problems: i.e. the study of the metallicity, evolution and clustering of the primordial Lyman alpha forest, tracing the nucleosynthetic history and element depletion pattern in the ISM of high redshift galaxies, determining if dark- matter halos are ubiquitous, and studying metal abundance analyses of stars. Six detectors are placed tangent to the focal sphere of a Schmidt camera. Each has its own thin field flattener. In this way excellent image quality is maintained while the obscuration by the detector array is minimal, even though it is big enough to cover the entire cross dispersed spectrum. Each back-illuminated CCD is dedicated to a limited spectral range, and can be given appropriately optimized coatings for highest efficiency. Designs for 20 and 30 cm beams have been produced, both using 60 cm Schmidt plates and achieve resolving power slit width products of 50,000 arcseconds. The 2048 square CCDs yield spectral resolution sampling of 200,000/pixel. The `point and shoot' character of the spectrograph should result in simplified controls and software.
The Inner Sublayer of the Circular Muscle Coat in the Canine Proximal Colon: Origins of Spontaneous Electrical and Mechanical Activity. (1995)

In the canine proximal colon, tissue near the submucosal surface of the circular muscle layer produces spontaneous mechanical contractions, synchronized with electrical slow waves. Comparative physiological examination of tissue strips from various regions of the submucosa and circular muscle coat revealed that the characteristic smooth muscle tissue of the innermost sublayer of the circular muscle is required for this rhythmical phenomenon. Histological examination showed that tissues containing special smooth muscle cells form an inner sublayer of the circular muscle coat. These innermost muscle cells were distinguishable from the bulk circular muscle cells by the following features: 1) flattened and shorter shapes of the cell and nucleus, 2) numerous caveolae on the cell surface, 3) abundant mitochondria, and 4) frequent gap-junction formations. Neither slow waves nor spontaneous mechanical rhythmicities were recorded from the submucosal connective tissue or from the bulk circular muscle tissue without the inner sublayer. The thicker smooth muscle cells found in the submucosal border specimens were identical in histological features to the bulk circular muscles which produced no slow waves and no spontaneous contractions. Cellular elements in the interstitium, such as fibroblasts, mast cells and macrophages, were found in all tissue strips that were physiologically examined. Nerve elements were found in all the specimens; however, there was a unique nerve network probably corresponding to the plexus entericus (submucosus) extremus described by Stach (1972). It was concluded, therefore, that the inner sublayer characterized by special smooth muscle cells with a delicate nerve plexus is essential for producing spontaneous activities of the circular muscle coat in the canine proximal colon.
Overview (2020)

Christabess is a parody of Coleridge’s unfinished Gothic poem ‘Christabel’, and was published anonymously under the pseudonym ‘S. T. Colebritche’ in 1816. Coleridge’s poem had been in circulation in manuscript long before its first publication in Christabel; Kubla Khan: A Vision; The Pain of Sleep, and is thought to have been an influence on Scott’s Lay of the East Minstrel. Byron similarly admired ‘Christabel’. Indeed ‘Christabel’ was a sensation when it was first published, generating reviews that were for the most part negative and derisive. Between 1816 and 1832, no less than seven verse parodies of “Christabel” were published. Christabess echoes ‘Christabel’ at every opportunity – from its preface through to the structure of the poem itself. In terms of content Christabess makes ordinary the high Gothic constituents of Coleridge’s poem. Rather than castles and aristocrats Christabess reduces the characters of the poem to the lower orders of society.
TEMPLATE SYNTHESIS IN HYDRODYNAMICALLY-ALIGNED SUPRAMOLECULAR NANO-CHANNELS (2010)

This paper describes the template synthesis of polymers in nanosized channels of aligned supramolecular fibrous assemblies (supramolecular fibers) that are present in a gel strand (Figure 1). We found that the incorporation of hydrophobic monomers into the nanosized channels of the fibers results in the formation of highly aligned polymers along the axis of the gel strand. Moreover, we found that the mechanical strength of the gel strands is sufficient for them to be handled in a microfluidic channel. We believe that our strategy for synthesizing and handling aligned polymers is of interest from the viewpoint of manufacturing highly conductive organic wires and electronic devices requiring flexibility and/or a large surface area.
Unified web-based network management based on distributed object orientated software agents (2002)

This paper presents an architecture that provides a unified web interface to managed network devices that support CORBA, OSI or Internet-based network management protocols. A client gains access to managed devices through a web browser, which is used to issue management operations and receive event notifications. The proposed architecture is compatible with both the OSI Management reference Model and CORBA. The steps required for designing the building blocks of such architecture are identified.
Abstract 9174: Global Variation in the Etiology and Management of Atrial Fibrillation: Results from a Global Atrial Fibrillation Registry (2011)

Background: Atrial fibrillation (AF) is the most common arrhythmia worldwide. A truly global registry is needed. Methods: The AF registry enrolled unselected patients who presented to an emergency department with AF. Results: A total of 14,434 patients were enrolled: 45% with AF as their primary diagnosis and 36% with their first documented episode of AF. The number of sites and patients were: North America (18; 1787), Latin America (23; 1116), Western Europe (19; 1903), Eastern Europe (22; 2445), Middle East (8; 813), Africa (20; 891), India (24; 2450), China (20; 1905) and Asia (12; 1124). The average age of patients in North America was 70.2 years and 57.7 % of patients were male. Patients in Africa and India were 12 years younger and were more likely to be female. Hypertension was the most common risk factor, present in 62% of patients worldwide. Its prevalence ranged from 41.5% in India to 80.0% in Eastern Europe. Heart failure was the second most common risk factor, present in 35% of patients worldwide. Its prevalence ranged from 17.4% in India to 70.5% in Africa. Rheumatic heart disease was present in only 2.1% of North American patients with AF, compared to 15.3% in both the Middle East and China, 22.0% in Africa and 30.9% in India. In Africa, more than 5% of AF cases were associated with pericarditis or endomyocardial fibrosis, while these conditions were present in &lt; 1% of patients elsewhere. In North America, the use of oral anticoagulation (OAC) among patients with AF and a CHADS 2 score of ≥ 2 was 72.6%. Elsewhere, the rate was from 19% in China to 63% in Eastern and Western Europe. For patients treated with OAC, the proportion of INR values between 2.0 and 3.0 ranged from 32.6% in India to 66.5% in Western Europe. Conclusions: Although advanced age, hypertension and heart failure are the most common predisposing conditions for AF in all regions, rheumatic heart disease remains an important cause in low-income countries. Appropriate use of OAC is low, particularly in low-income countries.
Design Strategies for Irregularly Adapting Parallel Applications. (2000)

Achieving scalable performance for dynamic irregular applications is eminently challenging. Traditional message-passing approaches have been making steady progress towards this goal; however, they suffer from complex implementation requirements. The use of a global address space greatly simplifies the programming task, but can degrade the performance of dynamically adapting computations. In this work, we examine two major classes of adaptive applications, under five competing programming methodologies and four leading parallel architectures. Results indicate that it is possible to achieve message-passing performance using shared-memory programming techniques by carefully following the same high level strategies. Adaptive applications have computational work loads and communication patterns which change unpredictably at runtime, requiring dynamic load balancing to achieve scalable performance on parallel machines. Efficient parallel implementations of such adaptive applications are therefore a challenging task. This work examines the implementation of two typical adaptive applications, Dynamic Remeshing and N-Body, across various programming paradigms and architectural platforms. We compare several critical factors of the parallel code development, including performance, programmability, scalability, algorithmic development, and portability.

A computer graphics package for indoor radio channel simulation using a 2D ray tracing algorithm (2003)

A graphical user interface program that uses a ray tracing algorithm to predict the radio propagation in the indoor radio channel from the layout of the floor plan is presented. The program allows the user to interactively specify the location of the walls in the floor plan, the type of material in the construction, and the location of the radio transmitter and receiver. The ray tracing algorithm determines the magnitude, phase, time of arrival, and direction of every signal path between the specified radio transmitter and receiver when an RF pulse is transmitted. The accuracy of the model is examined by comparing the simulation results with results of empirical measurements made in a complex laboratory environment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Hyperglycemia modulates extracellular amyloid-β concentrations and neuronal activity in vivo (2015)

Epidemiological studies show that patients with type 2 diabetes (T2DM) and individuals with a diabetes-independent elevation in blood glucose have an increased risk for developing dementia, specifically dementia due to Alzheimer's disease (AD). These observations suggest that abnormal glucose metabolism likely plays a role in some aspects of AD pathogenesis, leading us to investigate the link between aberrant glucose metabolism, T2DM, and AD in murine models. Here, we combined two techniques – glucose clamps and in vivo microdialysis – as a means to dynamically modulate blood glucose levels in awake, freely moving mice while measuring real-time changes in amyloid-β (Aβ), glucose, and lactate within the hippocampal interstitial fluid (ISF). In a murine model of AD, induction of acute hyperglycemia in young animals increased ISF Aβ production and ISF lactate, which serves as a marker of neuronal activity. These effects were exacerbated in aged AD mice with marked Aβ plaque pathology. Inward rectifying, ATP-sensitive potassium (K(ATP)) channels mediated the response to elevated glucose levels, as pharmacological manipulation of K(ATP) channels in the hippocampus altered both ISF Aβ levels and neuronal activity. Taken together, these results suggest that K(ATP) channel activation mediates the response of hippocampal neurons to hyperglycemia by coupling metabolism with neuronal activity and ISF Aβ levels.
Neuroanatomy of Apathy and Disinhibition in Frontotemporal Lobar Degeneration (2009)

Caregiver stress in families of FTLD patients is due in large part to apathy and disinhibition. The anatomic distribution of cortical loss corresponding to these distressing social behaviors includes partially distinct areas within the frontal lobe.
Influence of periodic correlation properties of sequences on the sum capacity of CDMA systems (2002)

The paper investigates the influence of correlation properties of spreading sequences on the sum capacity of a CDMA channel, in which all users are in exact synchronism at their transmitters but the signals pass through multipath channels with small delay spread and one strong path. It is shown that if spreading sequences have favorable periodic correlation properties, the sum capacity can be maximized at the expense of the sequence length when the power is uniformly distributed over the paths.
