Audiometric Manifestations of Retrocochlear Lesions (1973)

The auditory behaviour of VIIIth nerve and central auditory lesions is described. Typical auditory test profiles in these lesions are discussed. Tone- and speech audiometry, the stapedius reflex tests and directional audiometry are recommended as first order tests for suspected eigth nerve lesions. An elevated stapedius reflex threshold is a very consistent finding in acoustic neuromas. This test in combination with the stapedius reflex decay test has proved sensitive enough to identify early lesions in the eighth nerve. Sound localization test or directional audiometry also are good indicators of early lesions of the eighth nerve and the brain stem. Supplementary information can be reached by using the tone decay test, Békésy audiometry, the ABLB-, SISI- and loudness discomfort level tests. Sensitized speech tests give valuable information in lesions of the central auditory pathways.Inte ett enda audiologiskt test kan ensamt pÅvisa en skada centralt om cochlean. I stället fÅr man använda ett relativt omfattande testbatteri och sammanställa resultaten av detta för en topisk diagnos. Ton- och talaudiometri, stapediusreflextest och riktningshörselprov är de känsligaste testen för att pÅvisa en skada pÅ N. VIII. Ytterligare hjälp ger tone decay-test, Békésy audiometri, Fowlers balansprov och SISI-test samt bestämning av obehagströskeln. Försvdrad talaudiometri ger värdefull information beträffande skador i hjärnstammen, de centrala hörselbanorna och hörselbarken. De audiologiska testresultaten mÅste analyseras tillsammans med vestibulöra och neurologiska fynd för att diagnosen skall kunna ställas.
An Approach for Accurate Modelling of Frequency Dependent Effects of a Double Circuit DC Transmission Line on Common Tower (1990)

This paper presents modified approximation techniques in modal frame for frequency dependent effects of a double circuit DC transmission line on common tower. Elements of transformation matrix and surge admittance are approximated with not only first but also second order transfer function. Also unstable terms are introduced. Addition of second order and unstable terms reduces approximation error. The transient calculation of the Bergeron type model with unstable terms was numerically stable. Also the paper describes a new smoothig method based on eigen vector tracing technique for frequency dependent effects.
Ten Blue Links on Mars (2016)

This paper explores a simple question: How would we provide a high-quality search experience on Mars, where the fundamental physical limit is speed-of-light propagation delays on the order of tens of minutes? On Earth, users are accustomed to nearly instantaneous response times from search engines. Is it possible to overcome orders-of-magnitude longer latency to provide a tolerable user experience on Mars? In this paper, we formulate the searching from Mars problem as a tradeoff between "effort" (waiting for responses from Earth) and "data transfer" (pre-fetching or caching data on Mars). The contribution of our work is articulating this design space and presenting two case studies that explore the effectiveness of baseline techniques, using publicly available data from the TREC Total Recall and Sessions Tracks. We intend for this research problem to be aspirational and inspirational - even if one is not convinced by the premise of Mars colonization, there are Earth-based scenarios such as searching from a rural village in India that share similar constraints, thus making the problem worthy of exploration and attention from researchers.

Event-driven adaptive duty-cycling in sensor networks (2009)

Energy conservation is a major issue in the management of sensor networks. In this paper, we consider the problem of optimising the performance of energy-constrained sensor networks in the context of event-detection applications, with the performance metric being a weighted average of the numbers of missed events and false alarms. We propose two adaptive event-driven techniques, both simple to implement at the node level, that change the nodes' duty cycles based on the patterns of detected events. Simulation results show that this approach is effective in both cutting down wasteful energy consumption as well as in improving the detection performance in applications characterised by long periods of quiescence followed by bursts of activity.
Identification of Process-Localized mRNAs from Cultured Rodent Hippocampal Neurons (2006)

The regulated translation of localized mRNAs in neurons provides a mechanism for spatially restricting gene expression in a synapse-specific manner. To identify the population of mRNAs present in distal neuronal processes of rodent hippocampal neurons, we grew neurons on polycarbonate filters etched with 3 microm pores. Although the neuronal cell bodies remained on the top surface of the filters, dendrites, axons, and glial processes penetrated through the pores to grow along the bottom surface of the membrane where they could be mechanically separated from cell bodies. Quantitative PCR and immunochemical analyses of the process preparation revealed that it was remarkably free of somatic contamination. Microarray analysis of RNA isolated from the processes identified over 100 potentially localized mRNAs. In situ hybridization studies of 19 of these transcripts confirmed that all 19 were present in dendrites, validating the utility of this approach for identifying dendritically localized transcripts. Many of the identified mRNAs encoded components of the translational machinery and several were associated with the RNA-binding protein Staufen. These findings indicate that there is a rich repertoire of mRNAs whose translation can be locally regulated and support the emerging idea that local protein synthesis serves to boost the translational capacity of synapses.

Eggshell membrane: A possible new natural therapeutic for joint and connective tissue disorders. Results from two open-label human clinical studies (2009)

BACKGROUND: Natural Eggshell Membrane (NEM(®)) is a novel dietary supplement that contains naturally occurring glycosaminoglycans and proteins essential for maintaining healthy joint and connective tissues. Two single center, open-label human clinical studies were conducted to evaluate the efficacy and safety of NEM(®) as a treatment for pain and inflexibility associated with joint and connective tissue disorders. METHODS: Eleven (single-arm trial) and 28 (double-arm trial) patients received oral NEM(®) 500 mg once daily for four weeks. The primary outcome measure was to evaluate the change in general pain associated with the treatment joints/areas (both studies). In the single-arm trial, range of motion (ROM) and related ROM-associated pain was also evaluated. The primary treatment response endpoints were at seven and 30 days. Both clinical assessments were performed on the intent-to-treat (ITT) population within each study. RESULTS: Single-arm trial: Supplementation with NEM(®) produced a significant treatment response at seven days for flexibility (27.8% increase; P = 0.038) and at 30 days for general pain (72.5% reduction; P = 0.007), flexibility (43.7% increase; P = 0.006), and ROM-associated pain (75.9% reduction; P = 0.021). Double-arm trial: Supplementation with NEM(®) produced a significant treatment response for pain at seven days for both treatment arms (X: 18.4% reduction; P = 0.021. Y: 31.3% reduction; P = 0.014). There was no clinically meaningful difference between treatment arms at seven days, so the Y arm crossed over to the X formulation for the remainder of the study. The significant treatment response continued through 30 days for pain (30.2% reduction; P = 0.0001). There were no adverse events reported during either study and the treatment was reported to be well tolerated by study participants. CONCLUSIONS: Natural Eggshell Membrane (NEM(®)) is a possible new effective and safe therapeutic option for the treatment of pain and inflexibility associated with joint and connective tissue (JCT) disorders. Supplementation with NEM(®), 500 mg taken once daily, significantly reduced pain, both rapidly (seven days) and continuously (30 days). It also showed clinically meaningful results from a brief responder analysis, demonstrating that significant proportions of treated patients may be helped considerably from NEM(®) supplementation. The Clinical Trial Registration numbers for these trials are: NCT00750230 and NCT00750854.
Latest Advances in Cryogel Technology for Biomedical Applications (2019)

Abstract There exists a technological need for advanced materials with improved properties for emerging biomedical applications. Recent developments in macroporous materials have demonstrated their applicability as indispensable tools in biomedical research. Cryogels, which are materials with a macroporous 3D structure, are produced as a result of controlled freezing during polymerization with a highly interconnected polymer network. Cryogels’ interest lies in their ability to address some of the limitations of their hydrogel analogues. In this review, hydrogel and cryogel basic concepts are discussed as a short primer for readers unfamiliar with the cryogels literature. Next, a general overview of the methods for synthesis and characterization of cryogels is provided, highlighting key concepts relevant to cryogels and explaining their unique properties. Finally an in‐depth overview of specific technologies and fields where cryogels have been applied is given. It is argued that the latest advances in cryogel technologies are able to address challenges in bioseparation, tissue engineering, and other emerging bioengineering disciplines.
Coenzyme Q10 in the Human Retina (2009)

CoQ10 levels in the retina can decline by approximately 40% with age. This decline may have two consequences: a decrease in antioxidant ability and a decrease in the rate of ATP synthesis in the retina and, as such, this decline may be linked to the progression of macular degeneration.
Improved structural preservation of high-pressure frozen cartilage (1993)

Adult cartilage is a unique tissue in that it is avascular and lacks innervation. The chondrocytes are embedded in an extracellular matrix which in most cases occupies 60 to 90% of the tissue volume. The ultrastructure and composition of rat growth plate cartilage has been investigated (1). It was found that during conventional chemical fixation of me tissue (2), about 60% of the extracellular matrix proteoglycans were lost (3). This artefact can be prevented if proteoglycans are precipitated by cationic dyes (eg. ruthenium hexaamine trichloride) during fixation (4) which forms relatively large precipitates by rendering high resolution imaging impossible. High pressure frozen extracellular matrix revealed a fine meshwork which was attributed to proteoglycan distribution (5). A meshwork due to segregation during freezing was not seen in recent experiments where adaequately frozen cartilage was investigated. 200μm thick sections of rat growth plate cartilage were excised in a bath of hexadecene (6). The sections were again processed under hexadecene, firstly punched (diameter 1.7mm) and then transferred to an aluminum sandwhich (corresponding in size to the sample).
Spectral propagation algorithm for RCS of perfectly conducting cavities (1992)

An iterative spectral propagation algorithm is developed which introduces new features that improve the numerical efficiency and accuracy of the spectral iteration technique and the spectral incremental propagation procedure. The new spectral algorithm is particularly useful for analyzing closed problems where the boundary structure is too large for low-frequency matrix methods and too complex for high-frequency approximations. The scope of application includes the radar cross section of cavities, waveguide discontinuities and filters, and conformed or corrugated horn antenna analysis. The method is also valid for scattering problems in free space, but the continuous spectrum of nonperiodic fields together with the periodicity of the discrete Fourier transform require a very high number of field samples. For that reason, the efficiency of the algorithm may be worse than that of matrix methods for very complex scatterers and worse than that of high-frequency methods for large and simple objects. The main drawback is that boundary conditions are restricted to perfect electric or magnetic conductors, so that electric loading cannot be considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Hidden breakpoints in genome alignments (2012)

During the course of evolution, an organism's genome can undergo changes that affect the large-scale structure of the genome. These changes include gene gain, loss, duplication, chromosome fusion, fission, and rearrangement. When gene gain and loss occurs in addition to other types of rearrangement, breakpoints of rearrangement can exist that are only detectable by comparison of three or more genomes. An arbitrarily large number of these "hidden" breakpoints can exist among genomes that exhibit no rearrangements in pairwise comparisons. We present an extension of the multichromosomal breakpoint median problem to genomes that have undergone gene gain and loss. We then demonstrate that the median distance among three genomes can be used to calculate a lower bound on the number of hidden breakpoints present. We provide an implementation of this calculation including the median distance, along with some practical improvements on the time complexity of the underlying algorithm. We apply our approach to measure the abundance of hidden breakpoints in simulated data sets under a wide range of evolutionary scenarios. We demonstrate that in simulations the hidden breakpoint counts depend strongly on relative rates of inversion and gene gain/loss. Finally we apply current multiple genome aligners to the simulated genomes, and show that all aligners introduce a high degree of error in hidden breakpoint counts, and that this error grows with evolutionary distance in the simulation. Our results suggest that hidden breakpoint error may be pervasive in genome alignments.
Phase Shift Control of Combustion Instability in a Gas Turbine Matrix Burner Using Acoustic Forcing and Pulsed Fuel Injection (2009)

This paper reports the successful attenuation of self-exciting thermoacoustic instabilities inside a gas turbine matrix burner using phase-shift control. The test rig configuration is a matrix burner suitable for simulating the conditions prevailing in stationary gas turbines. The geometry consists of three main parts: 1. a mixing chamber where gaseous fuel is injected into the incoming air stream, 2. a contraction into several small slots which prevents upstream flame propagation, and 3. the combustion chamber. The fuel is first injected upstream before a high incoming velocity air forces it to move downstream. This design enhances fuel/air mixing by increasing the residence time of the mixture in the mixing chamber. But, introducing this time lag will lead to combustion instability in the matrix burner if it is approximately in phase with an integer multiple of the acoustic period. Phase shifting was done using a loudspeaker in one case and a fast response injector in another case to modulate the inlet air and primary fuel streams respectively. The dominant modes in each case were successfully suppressed with that due to the loudspeaker achieving a 45% reduction and the pulsed primary fuel injection achieving a 70% reduction. In both cases, however, secondary peaks were generated due to a coupling of the controller and the dynamics of the test rig. PIV measurements of the cold flow velocity field are first reported and compared with CFD results. This is followed by the determination and the explanation of the stability map of the matrix burner from measurements. Finally the pressure monitored inside the combustor of the matrix burner using unsteady CFD is validated with that obtained from microphone measurements.
Microstructure and magnetic properties of perpendicular media with reduced grain size (2009)

A new approach to control the grain size of Co alloy oxide perpendicular media by means of Ar-ion etching is presented. Ar plasma was applied to the surface of a continuous Ru1 layer, on top of which a granular Ru2+SiO2 layer was subsequently deposited. It was found that etching time and high Ar-ion energy have a significant effect on the surface roughness of the seedlayer, which in turn have a great effect on microstructure and magnetic properties of the media. A granular Ru2+SiO2 layer with mean grain size of 3.9±0.7 nm was obtained, and its oxide boundary thickness decreased with the decreasing Ru grain size. As a result, the mean grain size of the magnetic layer was greatly reduced to 5.3±0.8 nm from 7.6±1.3 nm of a controlled sample without Ar-ion etching. The coercivity (Hc) of the media is 2.7 kOe, while Hc of the controlled sample is 4.8 kOe. The small CoPt grain size, the possible oxidization of metal grains, and the resultant increasing c-axis dispersion of the magnetic layer can explain the decreasing Hc and remanent magnetization (Mr) and increasing (Hn−Hc) values of the perpendicular MH loops.
Timing control for synchronizing multimedia streaming over heterogeneous networks (2013)

With the advent of new devices such as smart TV, a single device can have connectivity with multiple heterogeneous networks. Various types of sophisticated services can be realized with the combined use of services from multiple heterogeneous networks. This paper studies timing control when integrating and synchronizing multiple streaming services which are delivered over heterogeneous network such as broadcast network and Internet. It uses the presentation time of the contents in providing synchronization to the multiple streams. The proposed method can be considered in providing synchronization to two or more streaming services that are delivered over the heterogeneous network.
DEVELOPMENT OF A HIGH TEMPERATURE IMPREGNANT. Final Report (1955)

Selenophosphate synthetase, the Escherichia coli selD gene product, is a 37-kDa protein that catalyzes the synthesis of selenophosphate from ATP and selenide. In the absence of selenide, ATP is converted quantitatively to AMP and two orthophosphates in a very slow partial reaction. A monophosphorylated enzyme derivative containing the gamma-phosphoryl group of ATP has been implicated as an intermediate from the results of positional isotope exchange studies. Conservation of the phosphate bond energy in the final selenophosphate product is indicated by its ability to phosphorylate alcohols and amines to form O-phosphoryl- and N-phosphoryl-derivatives. To further probe the mechanism of action of selenophosphate synthetase, isotope exchange studies with [8-14C]ADP or [8-14C]AMP and unlabeled ATP were carried out, and 31P NMR analysis of reaction mixtures enriched in H218O was performed. A slow enzyme-catalyzed exchange of ADP with ATP observed in the absence of selenide implies the existence of a phosphorylated enzyme and further supports an intermediary role of ADP in the reaction. Under these conditions ADP is slowly converted to AMP. Incorporation of 18O from H218O exclusively into orthophosphate in the overall selenide-dependent reaction indicates that the beta-phosphoryl group of the enzyme-bound ADP is attacked by water with liberation of orthophosphate and formation of AMP. Based on these results and the failure of the enzyme to catalyze an exchange of labeled AMP with ATP, the existence of a pyrophosphorylated enzyme intermediate that was postulated earlier can be excluded.
High-frequency pattern extraction in digital integrated circuits using scanning electrostatic force microscopy (1995)

The ability to perform noninvasive logic analysis at the internal points of integrated circuits is crucial in the design and test of advanced microelectronics. We present a noncontact scanning probe technique for extracting high-frequency digital patterns at internal points of an integrated circuit. The digital waveforms are determined by sensing the localized electrostatic force between a small probe and point on the circuit being measured. The force is monitored by detecting the deflection of the probe using a fiber-optic interferometer. The bandwidth of force measurements made using proximal probes are typically limited by the mechanical frequency response of the probe. In the presented instrument high-frequency bit-by-bit digital pattern measurements are enabled by using a pulse sampled heterodyne technique. In conjunction with a nulling approach, the technique is capable of measurements without complex calibration or probe positioning, and can be performed over passivated structures. A simple procedure is also presented which corrects errors due to nonidealities of the pulse sampling waveform. Using a probe with a kHz resonant frequency, Mbit/s patterns have been measured. Errors due to coupling from adjacent signal lines and due to surface charge effects are examined.
Efficient single-node broadcast in switched-based network of workstations with network partitioning (2002)

This paper proposes two efficient single-node broadcasting schemes for a network of workstations (NOW) based on a network-partitioning concept. To broadcast a message, the scheme works in three phases. First, we partition the network into two sub-networks (data-distributed networks, DDN). The broadcast message is evenly divided into two sub-messages, each being sent to one representative node in each subnetwork. Second, each sub-message is distributed in its subnetwork independently. Finally, through a sub-message combination step, each node obtains the whole broadcast message. Two network-partitioning schemes, namely 0-1 partitioning and odd-even partitioning, are proposed. Through simulations on irregular and regular networks, we confirm the average latency of these schemes achieve performance improvement compared with the optimal broadcast scheme.
