A Method for Measurement of Losses in the Noise-Matching Microwave Network While Measuring Transistor Noise Parameters (1987)

A new method for measuring the loss of a tuner network used as the noise-source admittance transformer in a noise parameter test set is presented. Since the method is based on noise figure measurements, the tuner losses are determined on-line while performing measurements for determining transistor noise parameters. Experiments carried out on a coaxial slide-screw tuner by means of a computer-assisted measurement setup are reported.
Singular Point, Organizing Center and Acupuncture Point (1989)

A hypothesis is proposed on the nature of acupuncture point and organizing center, the role of meridian system in growth regulation, and the mechanism of acupuncture. Both organizing centers and acupuncture points have low electric resistance. The low electric resistance is related to the distribution of gap junction and thus intercellular communication. Some acupuncture points may be organizing centers. The meridian system is important in coordination and regulation of morphogenesis. The properties of organizing centers and acupuncture points can be explained in view of singular point. Coupling and oscillation may underlie the mechanism of acupuncture as well as growth regulation.

The Politics of Modern Childhood: American Socialisation and the Crisis of Individualism (2005)

This chapter traces the rise of a distinctively modern child-rearing practice in the United States,1 and it is important to identify, at the outset, the historically unprecedented features of the American case, arising from its unique time and place in Western modernisation. This will enable us to consider its implications for the wider politics of childhood and for processes of modernisation more generally. Given the on-going globalisation of the world economy, the chapter suggests that forms of social attenuation and fluidity are being precipitated which recall the nineteenth century American experience. At the same time, the globalisation of culture beams ubiquitous presentations of American youth culture to the world. This process, a fast-forwarding of the evolution of American socialisation from its nineteenth century origins to its 'logical' conclusion in a distinct world of youth, in effect defines the contemporary role of childhood for many who lack an alternative scenario of child-rearing in the modernising process. This threatens, therefore, to make this more local 'crisis of socialization' a worldwide phenomenon (Barrett and McIntosh, 1991).
XRD and RBS study of annealing effects in titanium implanted a-silicon films (1989)

Abstract We have used ion implantation of 30 keV48Ti+ ions into a-Si films at nominal doses of 1020-1021 ions/m2 to fabricate coherent silicide layers. Characterization of these layers and study of their annealing behaviour were carried out using XRD and RBS techniques. We find that the layers are a mixture of Ti5Si4, TiSi, TiSi2 and Si. On annealing at relatively lower temperatures (up to ∼ 300° C), predominant silicide phases present in the layer are Ti-rich, such as Ti5Si4 and TiSi. At higher temperatures, the Ti-rich layer has a tendency to consume unreacted Si from the film and to form a predominantly Si-rich silicide layer. A structure of silicon different from the diamond cubic structure is noticed in these implanted layers.
Investigation of the medicinal significance of phytic acid as an indispensable anti-nutrient in diseases (2019)

Summary: Background & aims: Inadequate knowledge and intake of a balance diet is a contributing factor of micronutrient deficiencies in developing countries. Phytic acid contributes in inhibiting the bioavailability of some micronutrients. In spite of the anti-nutritional effect of phytic acid, it is known to exhibit some medicinal effects. This study investigated the medicinal significance of phytic acid as an indispensable anti-nutrient in diseases. Methods: Relevant scientific literatures from the major databases such as Pubmed, Medline and Google Scholar. The keywords searched and reviewed in this study were phytic acid, anti-nutrients, minerals, diseases and plants. Results: The published peer reviewed literatures searched showed that phytic acid, though an anti-nutrient, plays an indispensable role directly or indirectly in several disease conditions. It exhibits antioxidant function, a property that qualifies it to possess multiple medicinal values like: anti-diabetic, anticancer, anti-inflammatory properties to mention a few. Its chelating property affects the absorption and toxicities associated with essential and nonessential heavy metals, a scenario that could prevent neurodegenerative diseases such as Alzheimer's, Parkinson diseases and other related diseases. Conclusion: The medicinal values of phytic acid outweighed its negative impact. Hence, there is critical need for developing countries to improve on the dietary pattern of its people in addition to nutrition education. Keywords: Phytic acid, Minerals, Anti-Nutrients, Plants, Diseases
The Ultraviolet Spectra of Three N-Type Carbon Stars (1981)

The paper reports the successful detection of the ultraviolet spectra of three N-type carbon stars: BL Ori, TX Psc, and T Ind. Exposures of approximately 2-3 hours with the LWR camera of the IUE Satellite at low dispersion were necessary to record the ultraviolet flux. The shortward extension of the photospheric continuum is well exposed down to about 2800 A, with strong molecular and atomic absorption features. The spectrum appears not to be seriously affected by the unknown opacity source which blankets N stars (especially redder ones) in the violet. Emission lines of Mg II (h and k) and C II (2325 A) are conspicuous, indicating the presence of chromospheres in the stars. The ratios of integrated fluxes in the Mg II lines and C II lines to bolometric flux are respectively much smaller and slightly smaller than values observed in oxygen-rich M giants and supergiants.
Neurophysiological Evidence May Predict the Outcome of Sacral Neuromodulation (2003)

Our study confirms previous observations that SNM acts by the afferent pathway at the cortical site level and it sheds light on so-called idiopathic lower urinary tract symptoms. A modification of SEPs induced by SNM seems to be a prognostic factor of clinical outcomes. The action of SNM on the afferent pathway from the sacral area to the somatosensory cortex is specific and neurophysiological evaluation via pudendal SEPs provides evidence to this effect.
Analysis of Mitragynine and Metabolites in Human Urine for Detecting the Use of the Psychoactive Plant Kratom (2012)

The leaves of the South Asian plant kratom are described as having stimulating effects at low doses, and opiate-like analgesic and euphoric effects at high doses. A long history of use and abuse has led to the classification of kratom as a controlled substance in its native Thailand and other South Asian countries. However, kratom is not controlled in the United States, and the ready availability of kratom has led to its emergence as an herbal drug of abuse. With the growing popularity of kratom, efficient procedures are needed to detect kratom use. In the current study, both ultra-high-performance liquid chromatography and high-performance liquid chromatography-tandem mass spectrometry methods have been developed and validated for monitoring the major alkaloids and metabolites found in urine following kratom use. The primary unique alkaloid mitragynine is quantified in human urine from 1.00-500.00 ng/mL using mitraphylline as an internal standard. In addition, two metabolites (5-desmethylmitragynine and 17-desmethyldihydromitragynine) and the related active, alkaloid 7-hydroxy-mitragynine, are simultaneously qualitatively monitored. The presence of analytes are confirmed by an information-dependent acquisition-enhanced product ion procedure generating full fragmentation data used to positively identify detected analytes. The validated method has been utilized for clinical and forensic analyses of urine for the detection of kratom use.
UnDeepVO: Monocular Visual Odometry through Unsupervised Deep Learning (2017)

We propose a novel monocular visual odometry (VO) system called UnDeepVO in this paper. UnDeepVO is able to estimate the 6-DoF pose of a monocular camera and the depth of its view by using deep neural networks. There are two salient features of the proposed UnDeepVO: one is the unsupervised deep learning scheme, and the other is the absolute scale recovery. Specifically, we train UnDeepVO by using stereo image pairs to recover the scale but test it by using consecutive monocular images. Thus, UnDeepVO is a monocular system. The loss function defined for training the networks is based on spatial and temporal dense information. A system overview is shown in Fig. 1. The experiments on KITTI dataset show our UnDeepVO achieves good performance in terms of pose accuracy.
The effects of daily-wear contact lenses on contrast sensitivity in selected professional and collegiate female tennis players. (1993)

Contrast sensitivity (CS) has recently emerged as an important predictor of visual performance. Few studies, however, have been published involving CS and its role in vision for sport. The purpose of this investigation was to determine if significant differences occurred in CS between female professional and collegiate tennis players who wore daily-wear soft contact lenses (N = 10) and those players who wore no corrective lenses (N = 10) in competition as measured by the Stereo Optical Optec 2000 Vision Tester. Subjects were between the ages of 18 and 37 years. Mean ages were 21.76 (+/- 4.018) and 25.40 (+/- 5.379) years for those wearing lenses and those not, respectively. Each subject was preliminarily screened for SVA-distance, lateral/vertical phorias, stereopsis, and color perception. All subjects were within accepted limits. CS was assessed at 1.5, 3, 6, 12, and 18 cycles per degree (cpd). Each subject was assessed monocularly; eye initially assessed was determined randomly. A 2 x 2 factorial analysis of variance (alpha = .05) was used to analyze data. No significant differences were found between eyes. Significant differences were found at 3, 6, 12, and 18 cpd. It may be concluded that those female professional and collegiate tennis players wearing no corrective lenses were significantly higher in CS at intermittent and high spatial frequencies than those who wore daily-wear soft contact lenses in competition.
Nutrition and Inflammatory Bowel Disease: Its Relation to Pathophysiology, Outcome and Therapy (2003)

Nutritional deficiencies are frequent in patients with ulcerative colitis and Crohn's disease, and negatively influence the outcome of the disease. Growth retardation, osteopenia and thromboembolic phenomena are some of the inflammatory bowel disease complications in which nutritional deficits are involved. Moreover, nutrients can play a role in the pathogenesis of the disease and, in some cases, can be a primary therapeutic tool. Enteral nutrition has proven to play a therapeutic role in Crohn's disease. The nutrient(s) responsible for this effect are not well identified but dietary fat appears to be a major factor. In ulcerative colitis, unabsorbable carbohydrates can modulate the intestinal microbial environment, thus contributing to improve colonic inflammation.

Hybrid Video Coding Design With Variable Size Integer Transforms And Structural Similarity (2008)

This research proposes a block-based video codec design with two objectives. The first goal is to propose a method for intraframe that improves the rate-distortion (peak signal-to-noise ratio versus bit rate) of a fixed-size transform encoder. The proposed method uses three integer transform sizes (4x4), (8x8), and (16x16). The codec also adopts H.264-like spatial prediction to intraframe encoding. For simplicity of the design, Huffman variable-length code is used as entropy encoding. For intraframe encoding, the simulations show rate-distortion improvement over JPEG and JPEG2000. In some test sequences, the simulations also show improvement over H.264 (baseline profile at low complexity mode without rate-distortion optimization) with a small increase of operations on each macroblock at the decoder side. The second goal of this research is to study rate-distortion behavior of the interframe codec with novel motion estimation based on structural similarity (SSIM) and the codec with conventional motion estimation based on pixel error distortion (sum of absolute difference). A study from previous literature shows that the structural similarity metric provides better image assessment than a pixel error based metric (mean square error and peak signal-to-noise ratio). Structural similarity measurement on the true color components (RGB) with equal weight for each component is proposed. The results on rate-distortion show that both structural similarity and peak signal-to-noise ratio (PSNR) provide similar measurements. Both sum of absolute difference (SAD)- and structural similarity (SSIM)-based distortions in motion prediction of large block sizes, {(16x16), (8x8)}, have similar performances. For the small block size of (4x4), SAD-based distor-tion provides better rate-distortion performance. Distortion calculation for SSIM requires more operations compared to SAD.
Improved authentication algorithm for UMTS (2009)

Authentication process of user in mobile networks is an important issue. Previous standard of telecommunication Global System for Mobile Communication (GSM) has many security weaknesses. Under Third Generation Partnership Project(3GPP), new standard Universal Mobile Telecommunication System is developed. Which removes the security weaknesses of previous standards. However one security loop hole has been revealed in UMTS. It is the sending of International Mobile Subscriber Identity (IMSI) in plain text over the air interface. In this paper we introduce a security algorithm named as Airam, whose name is derived from developers of this algorithm. It resolves the problem of sending IMSI in plain text over the air interface by implementing asymmetric/symmetric cryptography techniques. We have presented simulation results of Airam algorithm that show how effciently Airam algorithm performs the user authentication process and its effectiveness against replay and imposition attacks.

SUV: A Novel Single-Update Version-Management Scheme for Hardware Transactional Memory Systems (2012)

In order to maintain the transactional semantics, Transactional Memory (TM) must guarantee isolated read and write operations in each transaction, meaning that it must spend a non-negligible and potentially significant amount of time on keeping track of the transactional modifications in its undo or redo log and switching to the proper version at the end of each transaction. Existing TMs failed to minimize the overheads incurred by these operations that are poised to impose more significant TM overheads in current and future many-core CMPs. A direct consequence of this is that extra and different data movements are needed to manage these modifications depending on commit or abort. To address this problem, we propose a novel Single-Update Version-management (SUV) scheme to redirect each transactional store operation to another memory address, track the mapping information between the original and redirected addresses, and switch to the proper version of data upon the transaction's commit or abort. There is only one data update (movement) in our SUV regardless of commit or abort, thus significantly reducing the TM overheads while allowing it to exploit more thread parallelism. We use SUV to replace version-management schemes in some existing hardware TMs to assess SUV's performance advantages. Our extensive execution-driven experiments show that SUV-TM consistently outperforms the state-of-the-art HTM schemes Log TM-SE, FasTM and DynTM under the STAMP benchmark suite. Moreover, we use CACTI to estimate the hardware overheads of SUV and find it is feasible in hardware implementation.
N-trifluoroacetyl derivatives as pharmacological agents. IV--Antiinflammatory and related properties; antimicrobial activity of some polyaromatic trifluoroacetamides. (1989)

Taking into account both the analogy with the antiinflammatory triflamides and our previous observations on a series of trifluoroacetanilides active as acute and chronic antiinflammatory agents, the present series of polyaromatic N-trifluoroacetylderivatives were prepared. Their antiinflammatory and related properties as well as antimicrobial activity were evaluated. Few derivatives were found to display significant analgesic effects (hot plate test) whereas at 50 mg/kg all were devoid of antiinflammatory effects except the benzophenone derivative (III). Instead as regards the antimicrobial screening, a selective antimycoplasmal activity was revealed in six out of ten examined compounds.
Instrumentation of a surfboard to evaluate surfing performance (2014)

This paper reports the development of a system to instrument a surfboard aiming to evaluate wave riding performance. According to the research only 3.8% – 5% of the total surfing time corresponds to the wave riding movements, despite of been the surfing goal. The system developed collects the data from twenty four force sensors positioned beneath the surfer's feet using a microcontroller ATMEGA1280, and determines the surfer's feet positioning and Centre of Pressure (CoP). Furthermore, an Inertial Measurement Unit (IMU) with an ADXL335 accelerometer and an IDG500 gyroscope provides information of the surfboard's position in relation to the gravity force axis. To store the result of the acquisitions a SD Card is used. To transmit the data to an external device such as a computer, a WI-FI module complete the electronic system. A battery management was used to allow the system to work remotely. This work presents an overview of the parameter recognized in literature as influencing athlete's performance and a brief description of the major manoeuvres in competition to figure out the parameters to be measured likewise the system developed. Preliminary tests with five different setups have shown that the force sensors to measure CoP and the electronic circuit board works properly.
Dietary Alteration of the Gut Microbiome and Its Impact on Weight and Fat Mass: A Systematic Review and Meta-Analysis (2018)

Dietary alteration of the gut microbiome is an important target in the treatment of obesity. Animal and human studies have shown bidirectional weight modulation based on the probiotic formulation used. In this study, we systematically reviewed the literature and performed a meta-analysis to assess the impact of prebiotics, probiotics and synbiotics on body weight, body mass index (BMI) and fat mass in adult human subjects. We searched Medline (PubMed), Embase, the Cochrane Library and the Web of Science to identify 4721 articles, of which 41 were subjected to full-text screening, yielding 21 included studies with 33 study arms. Probiotic use was associated with significant decreases in BMI, weight and fat mass. Studies of subjects consuming prebiotics demonstrated a significant reduction in body weight, whereas synbiotics did not show an effect. Overall, when the utilization of gut microbiome-modulating dietary agents (prebiotic/probiotic/synbiotic) was compared to placebo, there were significant decreases in BMI, weight and fat mass. In summary, dietary agents for the modulation of the gut microbiome are essential tools in the treatment of obesity and can lead to significant decreases in BMI, weight and fat mass. Further studies are needed to identify the ideal dose and duration of supplementation and to assess the durability of this effect.
