Ultrasonic Motors Using Longitudinal and Bending Multimode Vibrators with Mode Coupling by Externally Additional Asymmetry or Internal Nonlinearity (1992)

The present paper deals with some ultrasonic motors using longitudinal and bending multimode vibrators with their mode couplings caused by externally additional asymmetry or internal nonlinearity. A rectangular plate vibrator with two corners on one diagonal line cut to make its resonance modes couple with each other was used, along with a rectangular plate vibrator under the condition that two resonance frequencies are obtained, for example, as f L / f B =2.0, because internal nonlinear coupling of parametric vibration between two resonance modes is generated under this condition. Using these vibrators with mode couplings, it was found that some ultrasonic motors of simple form can be constructed. The ultrasonic motor using the phenomenon of mode-coupling vibrations dealt with here is not completely new, and a few trial constructions have already been reported [Jpn. J. Appl. Phys. 24 (1985) Suppl. 24-2, p. 739]. However, their motions were not reversible in ordinary driving with an electrical signal of a constant frequency. In contrast, the motors that the authors proposed in this paper can be expected to have a reversible motion.
Expression of the mouse Na-K-2Cl cotransporter, mBSC2, in the terminal inner medullary collecting duct, the glomerular and extraglomerular mesangium, and the glomerular afferent arteriole. (1996)

Na-K-Cl cotransport plays an important role in the kidney in NaCl reabsorption in the thick ascending limb of Henle and a less well defined role in the inner medullary collecting duct (IMCD). Two Na-K-Cl cotransporters encoded by different genes have been identified in the mammalian kidney: BSC1/NKCC2 which localizes to the apical thick ascending limb of Henle and BSC2/NKCC1 which was isolated from a mouse IMCD cell line (mIMCD-3) but its localization has not been determined. In this study we generated a polyclonal antibody (anti-mBSC2) against the mouse BSC2/NKCC1 protein in order to characterize and localize this protein in mouse kidney. Western blot analysis with affinity-purified anti-mBSC2 showed a protein doublet of 140 and 150 kD which was most abundant in the renal papilla but also seen in cortex and outer medulla. The 140-150-kD bands were not seen with preimmune serum or with anti-mBSC2 preabsorbed with specific antigen. Immunolocalization confirmed expression of mBSC2 protein on the basolateral surface of terminal IMCD segments and demonstrated expression in the papillary surface epithelium. Immunofluorescence also revealed the unexpected presence of the BSC2 protein at the juxtaglomerular afferent arteriole, in a juxtaglomerular structure probably representing the extraglomerular mesangium, and throughout the glomerular mesangium.
Detecting neurobehavioral changes in amyotrophic lateral sclerosis (2007)

Cognitive impairment in patients with amyotrophic lateral sclerosis (ALS) is well documented, but behavioral abnormalities are not well defined. The Frontal Systems Behavior Scale (FrSBe) was used to assess changes in apathy, disinhibition, and executive dysfunction in 45 patients with ALS. Results suggest a high incidence of behavioral change, most notably in apathy associated with the onset of the disease and independent of mood. Apathy and verbal fluency were correlated, lending further support to the hypothesis that an underlying continuum exists between ALS and frontotemporal dementia (FTD), which is characterized predominantly by behavioral disturbance. The FrsBe is useful for detecting behavioral change and abnormalities in patients with ALS.
Accuracy of OFDM ranging systems in the presence of processing impairments (2017)

Localization networks based on orthogonal frequency-division multiplexing (OFDM) ranging systems provide desirable location-awareness with commodity WiFi chipsets in harsh propagation conditions. Understanding the fundamental limits of OFDM ranging can guide the design and operation of these systems. Existing studies on these fundamental limits generally do not account for the processing impairments such as the estimation error of the phase offset and packet detection delay, yet ignoring processing impairments may lead to inaccurate evaluation of OFDM ranging accuracy. To address such inconsistency, we develop a framework to determine the fundamental limit of OFDM ranging, accounting for both channel parameters and processing impairments. In particular, we derive the equivalent Fisher information (EFI) for the propagation delay of the first path and quantify the effects of the number of multipaths, the number of channels, and processing impairments on the ranging accuracy through case studies. Numerical results verify the insights gained from the theoretical analysis.

The DNA Tetrahedron Nanostructure Materials and Their Applications (2015)

Nowadays,DNA tetrahedron nanostructure materials,formed by self-assembly based on DNA nanotechnology,have become a hot topic in the field of DNA nanomaterials because of their stable structures,superior mechanical properties,rich modification sites,and convenient fabrication methods with high yield.The synthesis of DNA tetrahedron only needs one step of thermal denaturation using four single nucleotides as raw materials.Their functionalization molecules can be modified on the vertexes,embedded between the doublestranded DNA of the tetrahedron edges,hanged on the edges,or encapsulated in the cage-like structure of the tetrahedron.The structure of tetrahedron can also be intelligently controlled through smart design such as integrating DNA hairpin loop structure onto the edges.This review introduces the design principle of the DNA tetrahedron nanostructure materials,the functionalization and intellectualization methods based on their unique nanostructure,as well as their applications on molecular diagnosis,bioimaging and targeted drug delivery,and finally discusses the considerations in the future research of this field.
Noise reduction in low-dose ct using a 3D multiscale sparse denoising autoencoder (2017)

This article presents a novel neural network-based approach for enhancement of 3D medical image data. The proposed networks learn a sparse representation basis by mapping the corrupted input data to corresponding optimal targets. To reinforce the adjustment of the network to the given data, the threshold values are also adaptively learned. In order to capture important image features on various scales and be able to process large computed tomography (CT) volumes in a reasonable time, a multiscale approach is applied. Recursively downsampled versions of the input are used and denoising operator of constant size are learnt at each scale. The networks are trained end-to-end from a database of real highdose acquisitions with synthetic additional noise to simulate the corresponding low-dose scans. Both 2D and 3D networks are evaluated on CT volumes and compared to the block-matching and 3D filtering (BM3D) algorithm. The presented methods achieve an increase of 4% to 11% in the SSIM and of 2.4 to 2.8 dB in the PSNR with respect to the ground truth, outperform BM3D in quantitative comparisions and present no visible texture artifacts. By exploiting volumetric information, 3D networks achieve superior results over 2D networks.

Arterial bifurcations in the human retina. (1979)

The branching angles and relative diameters of blood vessels in 51 arterial bifurcations in the retina of a normal human eye were measured. In eight other bifurcations, only the total branching angles were measured. The results are compared with theoretical predictions in an attempt to understand the physiological principles governing branching in the cardiovascular system.

Bacteriuria in patients with CDC group IV manifestations: a prospective study. (1991)

Health practitioners at the University Hospital of the Federal University of Rio de Janeiro in Brazil noted a high frequency of urinary tract infection (UTI) in AIDS patients. Therefore they enrolled 57 consecutive eligible male patients of the AIDS unit into a prospective study of bacteriuria. Exclusion criteria included previous history of UTI or renal stones genitourinary manipulation in the 6 months before the study or clinical evidence of prostatic disease. Average age was 33.47 years (range 21-49 years). Their risk factor distribution mirrored that of the HIV positive male population at the hospital. In included homosexuality/bisexuality (75%) intravenous drug users (7%) blood transfusions (3.5%) and heterosexuality (1.75%). The remaining 12.28% had undetermined risk factors. Laboratory personnel cultured a clean catch midstream urine specimen. Repeat result of >100000 c.f.u./ml and no UTI symptoms or single result of >100000 c.f.u/ml and UTI symptoms defined bacteriuria. 14.04% had bacteriuria. Positive cultures consisted of only gram negative bacilli especially Escherichia coli (62.5%). No one experienced back pain. In addition fever was not necessarily indicative of bacteriuria. 3 patients experienced pain when urinating which approached significance (p=.07). No statistically significant differences occurred in respect to age distribution risk factors history of sexually transmitted diseases hospital admissions or antibiotic use in the 6 months before the study. Since there was no control group it was difficult for the researchers to determine if the prevalence rate was higher than the general population. This study was 1 of few studies on bacteriuria in HIV infected patients. Further studies with control groups that investigate risk factors are needed.

Proposal on Objective Speech Quality Assessment for Wideband IP Telephony (2006)

We investigated the performance of the objective speech quality assessment method called "wideband PESQ", which has been proposed to ITU-T for quality assessment of wideband speech, for quality ranging from narrowband to wideband speech with packet-loss degradation. The experimental results show that although the relationship between wideband PESQ and subjective quality depends on the codec for wideband speech, wideband PESQ can be used quite well as an objective quality measurement for speech with packet-loss degradation as long as the same codec is used. This codec dependence, which is especially observed when evaluating wideband codecs, makes it difficult to consistently estimate the quality of speech coded by various kinds of codecs. To avoid this difficulty, we propose correcting objective scores based on a function prepared for each codec. This correcting function is predetermined based on the results of a subjective quality experiment. We show the validity of the proposed method in evaluating the speech quality of various codecs with packet-loss degradation.

Monolithic GaAs transimpedance amplifiers for fiber-optic receivers (1991)

The authors describe the design of transimpedance amplifiers using GaAs MESFET technology. A GaAs transimpedance preamplifier for fiber-optic receivers has been fabricated with two gain stages and an inducer-FET load structure that reduces noise. The two-stage amplifier design provides increased open-loop gain as compared with a single-stage design, and greater closed-loop stability than a three-stage amplifier. An automatic-gain-control (AGC) circuit that varied the value of the feedback resistor was incorporated into the design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
v-src induction of the TIS10/PGS2 prostaglandin synthase gene is mediated by an ATF/CRE transcription response element. (1994)

We recently reported the cloning of a mitogen-inducible prostaglandin synthase gene, TIS10/PGS2. In addition to growth factors and tumor promoters, the v-src oncogene induces TIS10/PGS2 expression in 3T3 cells. Deletion analysis, using luciferase reporters, identifies a region between -80 and -40 nucleotides 5' of the TIS10/PGS2 transcription start site that mediates pp60v-src induction in 3T3 cells. This region contains the sequence CGTCACGTG, which includes overlapping ATF/CRE (CGTCA) and E-box (CACGTG) sequences. Gel shift-oligonucleotide competition experiments with nuclear extracts from cells stably transfected with a temperature-sensitive v-src gene demonstrate that the CGTCACGTG sequence can bind proteins at both the ATF/CRE and E-box sequences. Dominant-negative CREB and Myc proteins that bind DNA, but do not transactivate, block v-src induction of a luciferase reporter driven by the first 80 nucleotides of the TIS10/PGS2 promoter. Mutational analysis distinguishes which TIS10/PGS2 cis-acting element mediates pp60v-src induction. E-box mutation has no effect on the fold induction in response to pp60v-src. In contrast, ATF/CRE mutation attenuates the pp60v-src response. Antibody supershift and methylation interference experiments demonstrate that CREB and at least one other ATF transcription factor in these extracts bind to the TIS10/PGS2 ATF/CRE element. Expression of a dominant-negative ras gene also blocks TIS10/PGS2 induction by v-src. Our data suggest that Ras mediates pp60v-src activation of an ATF transcription factor, leading to induced TIS10/PGS2 expression via the ATF/CRE element of the TIS10/PGS2 promoter. This is the first description of v-src activation of gene expression via an ATF/CRE element.

Temporal constraints of perceiving, generating, and integrating information: Clinical indications (1999)

Neuropsychological research on temporal constraints of perception and motor performance can add important information to research on human behavior. Without considering temporal mechanisms of perceiving, generating, and updating information, brain mechanisms can never be fully understood. In this study temporal aspects of performance in psychophysical experiments on three different temporal levels (around 30 ms, 300 ms, and 3000 ms) were investigated in patients with acquired brain lesions and a control group without neurological deficits. The patients had acquired focal brain lesions in: anterior (pre-central) regions of the left hemisphere (with non-fluent aphasia), posterior (post-central) regions of the left hemisphere (with fluent aphasia), the left hemipshere in predominantly subcortical regions (without aphasia), or anterior (pre-central) or posterior (post-central) regions of the right hemipshere. Perception of temporal order (20 to 60 ms) was impaired in patients with left-hemispheric post-central lesions; repetitive voluntary action (300 to 500 ms) was affected mostly in patients with left hemi-spheric lesions, both pre-central and post-central; and a deficit in integrating (2000 ms to 3000 ms) information was most pronounced in patients with left and right pre-central lesions. These findings provide insight into the associations between different levels of temporal organisation and circumscribed regions of the neocortex.

A Novel Functional Human Eukaryotic Translation Initiation Factor 4G (1998)

Mammalian eukaryotic translation initiation factor 4F (eIF4F) is a cap-binding protein complex consisting of three subunits: eIF4E, eIF4A, and eIF4G. In yeast and plants, two related eIF4G species are encoded by two different genes. To date, however, only one functional eIF4G polypeptide, referred to here as eIF4GI, has been identified in mammals. Here we describe the discovery and functional characterization of a closely related homolog, referred to as eIF4GII. eIF4GI and eIF4GII share 46% identity at the amino acid level and possess an overall similarity of 56%. The homology is particularly high in certain regions of the central and carboxy portions, while the amino-terminal regions are more divergent. Far-Western analysis and coimmunoprecipitation experiments were used to demonstrate that eIF4GII directly interacts with eIF4E, eIF4A, and eIF3. eIF4GII, like eIF4GI, is also cleaved upon picornavirus infection. eIF4GII restores cap-dependent translation in a reticulocyte lysate which had been pretreated with rhinovirus 2A to cleave endogenous eIF4G. Finally, eIF4GII exists as a complex with eIF4E in HeLa cells, because eIF4GII and eIF4E can be purified together by cap affinity chromatography. Taken together, our findings indicate that eIF4GII is a functional homolog of eIF4GI. These results may have important implications for the understanding of the mechanism of shutoff of host protein synthesis following picornavirus infection.

The Infrared & Electro-Optical Systems Handbook. Emerging Systems and Technologies, Volume 8 (1993)

Abstract : The Infrared and Electro-Optical Systems Handbook is a joint product of the Infrared Information Analysis Center (IRIA) and the International Society for Optical Engineering (SPIE). Sponsored by the Defense Technical Information Center (DTIC), this work is an outgrowth of its predecessor, The Infrared Handbook, published in 1978. The circulation of nearly 20,000 copies is adequate testimony to its wide acceptance in the electro-optics and infrared communities. The Infrared Handbook was itself preceded by The Handbook of Military Infrared Technology. Since its original inception, new topics and technologies have emerged for which little or no reference material exists. This work is intended to update and complement the current Infrared Handbook by revision, addition of new materials, and reformatting to increase its utility. Of necessity, some material from the current book was reproduced as is, having been adjudged as being current and adequate. The 45 chapters represent most subject areas of current activity in the military, aerospace, and civilian communities and contain material that has rarely appeared so extensively in the open literature. Because the contents are in part derivatives of advanced military technology, it seemed reasonable to categorize those chapters dealing with systems in analogy to the specialty groups comprising the annual Infrared Information Symposia (IRIS), a Department of Defense (DoD) sponsored forum administered by the Infrared Information Analysis Center of the Environmental Research Institute of Michigan (ERIM); thus, the presence of chapters on active, passive, and countermeasure systems. It is organized into eight volumes. Volume 8, edited by Stanley Robinson of ERIM, treats emerging technologies such as unconventional imaging, synthetic arrays, sensor and data fusion, adaptive optics, and automatic target recognition.
