Sound transmission through an acoustic porous metasurface with periodic structures (2017)

We report an analytical, numerical, and experimental study of sound transmission through a metasurface fabricated by porous materials, detailing systematically the factors that influence acoustic properties. The design of the metasurface is composed of four elements with varying properties, which are aligned in a periodic manner. The structures are carefully designed to form a uniform phase shift profile in one period. It is able to refract an incidence wave in an anomalous yet controllable way. A good agreement of refraction behavior between simulated and experimental results is achieved by the study. Furthermore, we systemically summarize the relationships between the refraction and the incidence angles for structures with various ratios of wavelengths and period lengths. Remarkably, the study proves that the propagation directions and the number of refracted waves are only affected by period lengths at a specified frequency. The phase shift profile only has an influence on energy distribution in the refraction region. The study suggests that a careful design of phase shift profile plays an important role in controlling sound energy distribution of the periodic structure, which is vital for applying this kind of porous metasurface in sound absorption and isolation in the future.
Involvement and Therapeutic Potential of the GABAergic System in the Fragile X Syndrome (2010)

Many drugs have been developed that are able to modulate the GABAergic system, which is involved in anxiety, depression, epilepsy, insomnia, and learning and memory. The recent observation that the GABA(A) receptor is underexpressed in the fragile X syndrome, an inherited mental retardation disorder, therefore raised hopes for targeted therapy of the disorder. This review summarizes the lines of evidence that demonstrate a malfunction of the GABAergic system. The GABAergic system clearly emerges as an attractive target for therapy of the fragile X syndrome, and thus provides an excellent example of how genetic research can lead to unique opportunities for treatment.

Urbanization and the carbon cycle: Current capabilities and research outlook from the natural sciences perspective (2014)

Abstract This paper explores the urban carbon cycle from the natural sciences perspective, identifying key knowledge gaps and priority areas for future research. The combination of large, concentrated carbon fluxes and rapid change makes cities key elements of the carbon cycle and offers the potential for them to serve as “first responders” for climate action. Estimates of urban‐scale carbon fluxes are significantly more uncertain than at larger spatial scales, in part because past studies have mostly avoided local/urban scales where the mix of anthropogenic and natural fluxes is complex and difficult to observationally isolate. To develop effective emission reduction policies, we need to understand emission sources and how they may be changing. Such improved quantification and understanding of underlying processes at the urban scale will not only provide policy‐relevant information and improve the understanding of urban dynamics and future scenarios, but will also translate into better global‐scale anthropogenic flux estimates, and advance our understanding of carbon cycle and climate feedbacks across multiple scales. Understanding the relationship between urbanization and urban carbon flows requires intellectual integration with research communities beyond the natural sciences. Cities can serve as interdisciplinary process laboratories that are sufficiently constrained in both spatial and governance scale to support truly integrated research by the natural sciences, social sciences, and engineering. A thoughtfully crafted science research agenda that is grounded in sustained, dense observations relevant to estimating urban carbon fluxes and their controlling processes and is focused on a statistically significant sample of cities will advance our understanding of the carbon cycle.

In this paper a novel shape detection system is proposed consisting of accelerometer network laid out in regular grid formation. This system is specifically designed as a foundation for shape recognizing fabrics usable in medicine. Specifically, enabling production of clothing capable of posture recognition and biofeedback, for treatment of scoliosis and similar diseases. The result is a functioning 16 three-axis accelerometer prototype device and method of approximately reconstructing its shape in three dimensions with tested average error less than 1cm for surface of dimensions up to 24 × 24cm.
Wildflower Tolerance to Metolachlor and Metolachlor Combined with Other Broadleaf Herbicides (1993)

The tolerance of transplanted lanceleaf coreopsis (Coreopsis lanceolata L.), ox-eye daisy (Chrysanthemum leucantheum L.), purple cone flower [Echinacea purpurea (L.) Moench.], and blanket flower (Gaillardia aristata Pursh) to metolachlor was determined in field trials. Metolachlor at 4.5 kg·ha -1 (maximum use rate) and 9.0 kg·ha -1 (twice the maximum use rate) did not reduce stand or flowering of any wildflower species after one or two applications, although plants developed transient visible injury. Combining metolachlor with the broadleaf herbicides simazine or isoxaben resulted in unacceptable injury and stand reduction, especially in ox-eye daisy. Metolachlor plus oxadiazon was less injurious to the wildflowers than metolachlor plus either simazine or isoxaben. Treatments containing metolachlor controlled yellow nutsedge (Cyperus esculentus L.) by at least 89% in both experiments. Treatments containing isoxaben controlled eclipta (Eclipta alba L.). 100% in both studies. Chemical names used: N- [3-(1-ethyl-1-methylpropyl)-5-isoxazolyl]-2,6-dimethoxybenzamide (isoxaben); 2-chloro -N- (2-ethyl-6-methylphenyl) -N- (2-methoxy-1-methylethyl)acetamide (metolachlor); 3-[2,4-di-chloro-5-(1-methylethoxy)phenyl]-5-(1,1-dimethylethyl)-1,3,4-oxadiazol-2-(3 H) -one (oxadiazon); 6-chloro -N,N' -diethyl-1,3,5-triazine-2,4-diamine (simazine).

AC and DC Regimes of the Electrohydrodynamic Instabilities in Nematic Liquid Crystals (1971)

Abstract New experimental results on the electrophydrodynamic instabilites in nematics are presented. Joined with previously reported properties, they allow a general classification of these instabilities in term of one DC and two AC regimes. A quantitive explanation of the AC regimes is given, in the frame of the Carr-Helfrich model extended to time dependent phenomena.
MR Properties and Thermal Stabilities of Cu/Co/Cu/NiFe Multilayers (1994)

Cu/Co/Cu/NiFe multilayer films prepared by evaporation in an ultrahigh vacuum showed induced ferrimagnetism and giant MR properties. The slope of the linear part of the MR curve near zero field is sensitive to the coercive force and squareness ratio of magnetization of the NiFe layers. The maximum slope was 0.41 %/Oe for Cr(50Å)[Cu (50Å)/Co(10Å)/Cu(50Å)/NiFe(15Å)]×10. The annealing temperature dependence of the slope was due to the interdiffusion of NiFe and Cu layers. Improved thermal stability was obtained by the use of thicker NiFe layers.
Effect of Shape and Flow Control Devices on the Fluid Flow Characteristics in Three Different Industrial Six Strand Billet Caster Tundish (2011)

Fluid flow phenomenon in a tundish depends upon the shape of tundish. The change in the shapes can bring drastic change in the flow pattern and thus effect the fluid flow characteristics in the tundish. The signifiacnt effect of flow control devices on fluid flow phenomenon is also noticed. In the present work, investigation of fluid flow phenomenon was performed for the symmetrical half of a six strand tundish. Fluid flow pattern gets altered by changing the shapes of tundish and pouring chamber. The impact of this change results in a development of various flow patterns. These flow patterns are analysed for capturing the better inclusion flotation. The mathematical model has been validated by the experimental results of Singh and Koria for a single strand bare tundish.

Video Camera Log Used for Water Isolation in the Main Body "B" Pool, Elk Hills Field, Kern Co., California-Water and Oil Identification (1995)

ABSTRACT The Main Body ’B’ reservoir in the Elk Hills Field is a peripherally waterflooded, +400’ thick series of layered, turbidite Stevens sands. Permeability variation between layers adversely affects the vertical sweep, resulting in production from lower permeability oil sands dominated by production from higher permeability sands. This paper discusses the unique use of various tools to identify water zones to isolate and oil zones to stimulate. Tools used to identify water and oil entry are discussed with respect to their capabilities of identifying oil and water entry into the wellbore. Swept and unswept layers are identified and the confidence level to propose a water isolation remedial has been developed; The confidence level is based on the analysis of a video camera log, open hole logs, production logs and production tests. This analysis begins when a candidate well with a high water cut is shut in, and the afterflow is viewed with a video camera. Oil entry is identified and evidence of water entry is inferred. These observations are compared with results from production tests in offsets, electric logs showing processed layers in an offset redrill, and production logs, and a video camera log from the same well. Agreement in the data provides the confidence level regarding what zones to isolate as watered-out and what zones will produce economic oil rates after the remedial. If results from water isolation remedials are available, these results may also be reported.
Comparison of depth-based features for lipreading (2015)

We examine the effect of depth information captured by Microsoft Kinect on the task of visual speech recognition. We propose depth-based active appearance model (AAM) features and show improved results over discrete cosine transform (DCT). The visual and depth features are evaluated on a database of 54 speakers each uttering 50 isolated words. In order to exploit the speech dynamics, the features are enhanced by a simplified one-stage variant of hierarchical linear discriminant analysis (Hi-LDA). In the experiments, we consider feature fusion via combined video-depth active appearance model as a form of early integration, and compare it to traditional multi-stream hidden Markov Model as a form of decision fusion. We also perform experiments on audio-visual recognition in noisy environments and show improved results of incorporating depth information over both traditional audio-video fusion and utilization of speech enhancement algorithms.
MSS requirements for data acquisition systems (2002)

High-performance data acquisition systems differ in their general requirements in that they accept an input data stream that is essentially uninterruptible, purposefully collect multiple petabytes of data per year, and require near-real-time, high-performance processing on the input stream: the data object creation, storage, and usage domains. The characteristics of these three domains are described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Diagnostic and prognostic significance of miRNA signatures in tissues and plasma of endometrioid endometrial carcinoma patients (2012)

The aim of our study was to define tissue and plasma miRNA signatures, which could potentially serve as diagnostic and prognostic markers in endometrioid endometrial cancer (EEC) and to investigate miRNA profiles in regard to clinicopathological characteristics. Tissue and plasma samples were collected from 122 women (77 EEC and 45 controls). Expression profiling of 866 human miRNAs and 89 human viral miRNAs was performed in 24 samples and was followed by qPCR validation in 104 patients. Expression of 16 miRNAs was analyzed in 48 plasma samples. Microarray study revealed regulation of 21 miRNAs in EEC tissues comparing to normal endometrium. Altered expression of 17 miRNAs was confirmed by qPCR performed in 104 tissue samples. Seven miRNAs were upregulated and two were downregulated in EEC plasma samples. Expression of a number of miRNAs was associated with International Federation of Gynecology and Obstetrics stage, grade, relapse and nodal metastases. Two miRNA signatures: miR-92a/miR-410 and miR-92a/miR-205/miR-410 classified tumor tissues with higher accuracy in comparison to single miRNAs (AUC: 0.977, 95% CI: 0.927-0.996 and 0.984, 95% CI: 0.938-0.999, respectively). miRNA signature composed of miR-205 and miR-200a predicted relapse with AUC of 0.854 (95% CI: 0.691-0.951). Tissue miRNA signatures were independent prognostic markers of overall (miR-1228/miR-200c/miR-429, HR: 2.98) and progression-free survival (miR-1228/miR-429, HR: 2.453). Plasma miRNA signatures: miR-9/miR-1228 and miR-9/miR-92a, classified EEC plasma samples with high accuracy yielding AUCs of 0.909 (95% CI: 0.789-973) and 0.913 (95% CI: 0.794-0.976), respectively. We conclude that miRNA signatures hold a great promise to become noninvasive biomarkers for early EEC detection and prognosis.

Treatment of Ambulatory Hypertensives With Nebivolol or Hydrochlorothiazide Alone and in Combination (1994)

This placebo-controlled multifactorial design trial assessed the antihypertensive efficacy of nebivolol, a novel cardioselective beta 1-blocker with vasodilating properties, and hydrochlorothiazide monotherapy and in combination. After a 4-week placebo period, 240 white patients with a mean daytime ambulatory blood pressure of > or = 90 mm Hg were randomized to receive either placebo, nebivolol (1, 5, or 10 mg), hydrochlorothiazide (12.5 or 25 mg), or one of the six possible combinations of nebivolol and hydrochlorothiazide for 12 weeks. A dose-related reduction in clinic and ambulatory blood pressure was demonstrated for each drug as monotherapy and for the two drugs in combination. Nebivolol, 5- and 10-mg doses, showed a larger effect than hydrochlorothiazide doses on clinic blood pressure and over the 24-h interval. Moreover, the combination doses had substantial antihypertensive effects that were sustained over the entire 24-h profile with a greater effect observed with the higher dose combinations. The reduction in ambulatory blood pressure was further substantiated by the reduction of blood pressure loads (% of BP > 140/90 mm Hg awake and > 120/80 mm Hg asleep) to as low as 11.5% with 10 mg of nebivolol combined with 25 mg of hydrochlorothiazide. Nebivolol and hydrochlorothiazide were well tolerated. We provided evidence that nebivolol, given as monotherapy or in combination with low dose of hydrochlorothiazide, is effective in reducing clinic and 24-h ambulatory blood pressure in patients with ambulatory hypertension. The results provided further evidence for the use of ambulatory blood pressure monitoring and factorial designs when investigating new antihypertensive agents.
Parenteral methods of supplementation with copper and selenium (1984)

Parenteral treatments can provide a rapid successful method of supplementing ruminants with copper and selenium, and avoid the possible interactions between an oral supplement and other dietary constituents. The copper preparations studied contained copper complexed with calcium edetate (EDTA) or copper methionate , copper oxide or copper oxyquinoline sulphonate. The recommended doses of these commercial preparations contain different amounts of copper only part of which is transferred to the liver stores from which it can be released during the following months. The recommended dose of copper oxyquinoline sulphonate contains only 12 mg copper and the duration of its protective effect is short. Only a small proportion of the copper in copper methionate and copper oxide is transferred to the liver whereas nearly all the copper in a single dose of the EDTA complex (50 mg copper for sheep) is transferred to the liver stores. Although no longer recommended for use in sheep the copper EDTA complex can be administered to cattle to provide up to 1 mg copper/kg bodyweight. Selenium deficiency in both cattle and sheep can be corrected by the subcutaneous administration of up to 0.15 mg selenium/kg bodyweight as sodium selenate. However, if a dietary deficiency persists copper and selenium treatments are effective for only a few months. To avoid the need for repeated treatments, slowly dissolving or controlled release systems have been developed. Subcutaneous depots of barium selenate have been used (1 mg selenium/kg bodyweight) but large residues remained at the site of injection for up to three months. Initial trials with controlled release glasses containing copper have shown that they maybe useful for routine parenteral therapy.
ACCURATE SLIDE POSITIONING USING FAST ADAPTIVE-TEMPLATE MATCHING IN AN AUTOMATED MICROSCOPE (2014)

Abstract In an automated microscope, the stage presents the slide to the optical path in the desired position. This article presents an accurate slide positioning algorithm which finds the relative offset from the zero of off-line calibration when the standard slide with a ring fiduciary mark is loaded on the stage. The relative offset is the difference between the zero by the offset calibration tool and the real-time zero position of the ring mark computed by the scheme. The slide positioning algorithm utilizes the adaptive-template matching method to detect the ring mark precisely, in which a fast sum of absolute differences is employed to reduce the computational complexity of template matching. Computer simulations with real clinical slides containing epithelial debris and nuclei show that the proposed algorithm yields an accurate performance in terms of detecting the ring mark and estimating the relative offset with a great reduction in computational complexity.

Cold‐inducible zinc finger‐containing glycine‐rich RNA‐binding protein contributes to the enhancement of freezing tolerance in <i>Arabidopsis thaliana</i> (2005)

Glycine-rich RNA-binding proteins (GR-RBPs) have been implicated to play roles in post-transcriptional regulation of gene expression in plants under various stress conditions, but the functional roles of GR-RBPs under stress conditions remain to be verified. Here, we examine the biological roles of a GR-RBP, designated atRZ-1a, in Arabidopsis thaliana under stress conditions. atRZ-1a was expressed ubiquitously in various Arabidopsis organs including stems, roots, leaves, flowers, and siliques. The transcript level of atRZ-1a increased markedly by cold stress, whereas its expression was marginally downregulated by drought stress or abscisic acid treatment. Germination and seedling growth of the loss-of-function mutants were retarded remarkably compared with those of the wild type under cold stress. In contrast, the transgenic Arabidopsis plants that overexpress atRZ-1a displayed earlier germination and better seedling growth than the wild type under cold stress. Moreover, the atRZ-1a-overexpressing transgenic Arabidopsis plants were more freezing tolerant than the wild-type plants. Heterologous expression of atRZ-1a in Escherichia coli demonstrated that the E. coli cells expressing atRZ-1a displayed much higher growth rate than the non-transformed cells after cold shock. These results provide evidence that atRZ-1a affects seed germination and seedling growth under low temperature and plays a role in the enhancement of freezing tolerance in Arabidopsis plants.
