Target-Motion-Induced Radar Imaging (1980)

Imaging from ground-based (stationary) radars of moving targets is often possible by utilizing a "synthetic aperture" developed from the target motion itself. The theory and experimental results associated with such processing are addressed. An aircraft is imaged from both a straight flight and a turn with recognizable results. Analysis shows that two-phase components exist in the radar return, one being gross velocity induced, the other being interscatterer interference within the target itself. The former phase must be removed prior to imaging and techniques are developed for this task. Preprocessing, range curvature, range alignment, motion compensation, and presumming are all addressed prior to presenting the experimental results. Coherence processing intervals, range collapsing, and range realignment are all examined during the processing aspects of the paper.

Characteristics of deep-UV optics at 193 nm and 157 nm (1999)

The increasing use of Argon Fluoride (ArF) 193 nm excimer lasers in microlithography, surgical procedures and other applications have created the requirement for an increasingly larger number of specialized optical components and thin film coatings. At 193nm these include coated components that can withstand long duration exposure to UV radiation without significant change in performance. Similar coatings and components for Fluorine lasers operating at 157 nm are under development. At these deep UV wavelengths, potential coating materials as well as substrates are very limited due to absorption and impurities. Characteristics of various types of thin film coatings including reflective, anti-reflective, beam-splitting, beam attenuating and optical bandpass filters, at both 193nm and 157nm, are measured using a specially designed vacuum spectrophotometer system. Results of these measurements as well as plans for further coating development are presented.
The synthesis and lithographic evaluation of a new organosilicon novolac‐based resist (1988)

Abstract A novel material, bis (trimethylsilylmethoxy resorcinol) was synthesized by a phenoxide alkylation method. The new substituted resorcinol was then terpolymerized with 2‐methyl resorcinol and formaldehyde. We evaluated the preparation of this new polymer in terms of feed ratio of the reactants, reaction time, and temperature; and prepared a series of materials with different silicon content. Polymers which retained base solubility at high silicon content were blended with a dissolution inhibitor, and studied for their lithographic capabilities as positive, photo‐ or electron‐beam bilevel resists. When used in a photoresist formulation a dose of 120 mJ/cm 2 allowed formation of submicron features. When used in an electron‐beam resist formulation 0.5 μm line/space patterns were obtained at a dose of 10 μC/cm 2 . Furthermore, these materials displayed etching ratios relative to hardbaked HPR206 of ≃ 1 : 10. This value is believed to be large enough to allow these resists to withstand reactive ion etching conditions for pattern transfer in a bilevel scheme.
Withdrawal from glucocorticosteroid therapy: clinical practice recommendations (2008)

There is no good predictive test for predicting the risk of adrenal insufficiency in patients who have been on corticosteroid therapy chronically. There is a need for prospective studies to assess the true incidence of this problem and to propose rational strategies for preventing it. The current recommendation is that patients who have been on chronic and/or high dose glucocorticoids should be administered glucocorticoids during stress situations unless the integrity of the HPA axis has been established by dynamic tests.
Morphology‐Controlled Growth of Large‐Area Two‐Dimensional Ordered Pore Arrays (2004)

Abstract A solution‐dipping template strategy for large‐area synthesis of morphology‐controlled, ordered pore arrays is reported. The morphology of the pore array can easily be controlled by concentration of the precursor solution and treatment conditions. With decrease of the concentration from a high level to a very low level nanostructured complex (pore–hole, and pore–particle) arrays, through‐pore arrays, and even ring arrays can, in turn, be obtained. The pore size is adjustable over a large range by changing the diameter of the template's latex spheres. This synthesis route is universal and can be used for various metals, semiconductors and compounds on any substrate. Such structures may be useful in applications such as energy storage or conversion, especially in integrated next‐generation nanophotonics devices, and biomolecular labeling and identification.

Vasoactive intestinal peptide: A potent stimulator of adenosine 3′:5′-cyclic monophosphate accumulation in gut carcinoma cell lines in culture (1978)

Vasoactive intestinal peptide (VIP) is a potent and efficient stimulator of adenosine 3':5'-cyclic monophosphate (cAMP) accumulation in a human colon carcinoma cell line, HT 29. cAMP accumulation is sensitive to a concentration of VIP as low as 3x10(-12) M. Maximum VIP-induced cAMP levels were observed with 10(-9) M VIP and are about 200 times above the basal levels. Half-maximum cAMP production was obtained at 3x10(-10) M VIP. (125)I-Labeled VIP was found to bind to HT 29 cells; this binding was competitively inhibited by concentrations of unlabeled VIP between 10(-10) and 10(-7) M. Half-maximum inhibition of binding was observed with 2x10(-9) M VIP. Secretin also stimulated cAMP accumulation in HT 29 cells, but its effectiveness was 1/1000 that of VIP. The other peptides tested at 10(-7) M, such as insulin, glucagon, bovine pancreatic polypeptide, somatostatin, octapeptide of cholecystokinin, neurotensin, and substance P, did not stimulate cAMP accumulation. Prostaglandin E(1) and catecholamines stimulated cAMP production but were 1/2.3 and 1/5.5 as efficient as VIP, respectively. Another malignant cell line from the gut, the human rectal tumor cell line HRT 18, is also sensitive to VIP. In HRT 18 cells, VIP stimulated cAMP accumulation with a maximal effect at 10(-8) M; half-maximum stimulation was observed at about 10(-9) M. These results demonstrate the presence of VIP receptors in two malignant human intestinal cell lines (HT 29 and HRT 18) in culture and provide a model for studying the action of VIP on cell proliferation.
A comparative study of pancreatectomy and pancreas-preserving gastrectomy in advanced gastric carcinomas. (2004)

Since distal pancreatectomy does not benefit patients with advanced gastric cancer, this procedure should not be regarded as routine in a radical resection.

Moreover, we verified the necessity to remove those influences. And we proposed estimation formula of travel speed for general vehicle using bus probe data. In addition, it became possible to grasp a more precise traffic situation by considering the roadsid situation.
RBC acetyl cholinesterase: A poor man’s early diagnostic biomarker for familial alzheimer’s and Parkinson’s disease dementia (2014)

Below the normal RBC AChE level is a potential biomarker in asymptomatic relatives of familial AD patients. RBC AChE is raised than normal level in patients suffering from PDD, where AChE inhibitors are helpful. However, RBC AChE level below the normal where AChE inhibitor may not be effective.
Experimental chronic ocular hypertension by anterior chamber injection of 0.3% carbomer solution in the rat (2012)

Abstract Background To evaluate a chronic ocular hypertensive model by anterior chamber injection of 0.3% carbomer solution in rats. Methods Chronic ocular hypertension was induced unilaterally by injecting 20 μL of 0.3% carbomer solution into the anterior chamber in 3‐month‐old S prague D awley rats. Intraocular pressure was measured everyday for 1 week and then every week for 2 months after a single or repeated injection. Retinal ganglion cell loss was assessed quantitatively using F luoro G old labelling at 2, 4 and 8 weeks after injection. Anterior chamber angle and optic nerve were examined after chronic intraocular pressure elevation. Results The mean and peak intraocular pressure of the injected eyes were elevated significantly higher than those of the control eyes for 6 weeks of the experiment, after a single injection of carbomer solution and a second injection at 2 weeks resulted in an 8‐week elevation of the mean and peak intraocular pressure, which was significantly higher than those of the control eyes. Elevated intraocular pressure induced retinal ganglion cell loss by approximately 21%, 27% and 38% compared with that in the control eyes at 2, 4 and 8 weeks, respectively, after a single injection. In carbomer‐injected eyes with chronic intraocular pressure elevation, the obstruction of anterior chamber angle by peripheral anterior synechia and optic nerve degeneration were observed. Conclusions Anterior chamber injection of 0.3% carbomer solution was an effective and reproducible method to produce chronic intraocular pressure elevation and glaucomatous neurodegeneration in rats.
Circ_0011292 Enhances Paclitaxel Resistance in Non-Small Cell Lung Cancer by Regulating miR-379-5p/TRIM65 Axis (2020)

<b><i>Background:</i></b> Non-small cell lung cancer (NSCLC) is the most prevalent cancer in the world. Chemotherapy resistance is a major obstacle to NSCLC therapy. This study explored the role and molecular mechanism of circular RNA 0011292 (circ_0011292) in tumorigenesis and chemoresistance of NSCLC. <b><i>Methods:</i></b> The levels of circ_0011292, miR-379-5p, and tripartite motif-containing protein 65 (TRIM65) were measured by quantitative real-time polymerase chain reaction or Western blot assay. Cell proliferation was assessed by Cell Counting Kit-8 (CCK-8) assay. Cell apoptosis was monitored by flow cytometry. Cell migration and invasion were detected by transwell assay. The levels of apoptosis-related and epithelial-mesenchymal transition-related proteins were examined by Western blot. The half-inhibition concentration (IC50) of paclitaxel (PTX) was evaluated by CCK-8 assay. Xenograft model was established to analyze the effect of circ_0011292 on PTX resistance of NSCLC <i>in vivo</i>. The interaction among circ_0011292, miR-379-5p, and TRIM65 was verified by dual-luciferase reporter assay and RNA immunoprecipitation assay. <b><i>Results:</i></b> Circ_0011292 and TRIM65 were upregulated, while miR-379-5p was downregulated in NSCLC tissues and cells. Circ_0011292 knockdown hindered NSCLC progression and enhanced PTX sensitivity of NSCLC. Circ_0011292 silencing reduced PTX resistance <i>in vivo</i>. Besides, miR-379-5p potentiated PTX sensitivity by targeting TRIM65. Also, circ_0011292 increased PTX resistance by sponging miR-379-5p. <b><i>Conclusion:</i></b> Circ_0011292 facilitated tumorigenesis and PTX resistance in NSCLC by regulating the miR-379-5p/TRIM65 axis, suggesting that circ_0011292 was a promising therapeutic target for NSCLC chemotherapy.
Speech browsing the World Wide Web (2003)

The use of spoken language as an input modality can help overcome some limitations of pointer-based browsers and thus, improve the human-computer interaction for browsing the World Wide Web. A study was conducted to determine whether real users can be effective using speech for browsing and also to determine the users preferences for browsing between the speech and mouse modalities. The study revealed that the users adopt a no-nonsense approach for speech browsing in which they issue commands by saying one or two keywords. The most important finding of the study was that the choice for an interaction modality is governed more by the usability attribute of user satisfaction than by efficiency of use. Most users prefer to use speech over mouse, even if they can be quicker with a mouse, because it makes the interaction easier for them.
High Thermal Conductivity of Diamond Nanofluids and its Effect on the Heat Transport Capability in an Oscillating Heat Pipe (2006)

In heat exchangers and liquid cooling devices the thermal conductivity of the liquid is an important factor in their design. Recently it has been shown that adding small amounts of nanoparticles to the liquid can significantly increase the thermal conductivity of the fluid [1]. This study investigates the thermal conductivity of diamond nanofluid. The nanofluid is HPLC grade water with 1% by volume diamond nanoparticles that are 5-50 nm in diameter. The thermal conductivity was measured by the transient hot-wire method. In order to verify the experimental measurement, the thermal conductivity of pure water (HPLC grade) was conducted and the measurement error is 3.6%. The experimental results show that the diamond nanoparticles can enhance the thermal conductivity of nanofluid. At an ambient temperature of 21 °C, the thermal conductivity for nanofluid was determined to be 1.00 W/m-K comparing with the thermal conductivity of 0.60 W/m-K for pure water (HPLC grade). Therefore, the nanofluid provides a significant increase in thermal conductivity. Utilizing this nanofluid, an oscillating heat pipe was developed and tested. Experimental results showed that when the oscillating heat pipe is charged with diamond nanofluids, the increase in heat transport capability can be significant and highly dependent on the operating temperatures.
Experimental and Theoretical Study of Hypocycloidal Motors with Two-Harmonic Field Windings (1980)

Hypocycloidal motors are torque motors which represent an intermediate class between high velocity motors with a mechanical reducer and motors designed for normal work at low speed. In this paper, anew form of hypo cycloidal motors is presented, in which a simple three-phase stator winding, producing a two-harmonic field in the air gap, allows a notably simpler construction, and a considerable improvement of performance. The theoryof the new motor in its synchronous version is developed, and its transient performance is simulated, showing that the motor is able to start with large mechanical loads inserted, and to reach the synchronous speed with avery small angular error with respect to an ideal step starting. Finally, experimental results are described, which confirm theoretical previsions.
Decision Making Strategies for Intelligent Control system of Train Speed &#x00026; Train Dispatch in Iran Railway (2008)

As railway transportation is a monoblock system, smallest changes in a train movement cause many changes at timing program. Compensation of deviation from scheduling program in earliest time will cause optimal utilization from locomotive, wagon and line. Scheduling table contains information about arrival and dispatching and duration of stop time of each train in every station. It is assumed that scheduling table is accessible and goal is to propose program that has more adaptation with scheduling table of train movement at any moment. Laws like maximum permissible speed of line or maximum permissible speed of train and amount of existence noise, produce limitation in proposed control strategy. Two fuzzy systems are proposed for designing this system. 1) Fuzzy controller about speed of train that proposes specific speed at any moment. This system causes uniformity control on train movement and efforts for compensating changes from scheduling table as soon as it possible. This controller can act as an automatic train driver for conducting transporter. 2) Fuzzy controller about controlling of dispatching trains that if fuzzy controller about speed of train could not compensate delay of train until arrive to next station, centralize fuzzy controller in station decides for dispatching. This system proposes program has more adaptability with scheduling table of train movement. It must decide which train will have the preference to occupy the distance between stations and which must stop at a siding. This centralize fuzzy controller could be replaced instead of manpower.
Pattern‐evoked responses and luminance‐evoked responses in the human electroretinogram. (1983)

Electrical potentials were recorded from the cornea of the human eye in response to the onset and offset of square-wave stripe patterns varying in spatial frequency, luminance and contrast. Under high retinal illumination (50119 photopic td) the response to pattern onset was a positive wave (pattern-onset wave) followed by a negative after-potential. As long as the pattern was presented, a steady potential of positive polarity (plateau potential) was observed. The response to pattern offset was a biphasic negative-positive wave followed by a negative after-potential. A comparison between wave forms obtained with pattern onset-offset stimuli and luminance increase-decrease stimuli suggests: (a) the pattern-onset wave is the result of an interaction between a luminance-increase and a luminance-decrease response; (b) the plateau potential is mainly an additive superposition of two receptor processes originating from retinal areas that receive increases and decreases in local luminance; (c) the negative-positive potential is an a-wave and a b-wave originating from retinal areas that receive increases in local luminance. The amplitude of the pattern-onset wave was greatest at a spatial frequency around 3-4 c/deg. This behaviour was closely correlated with contrast sensitivity determined psychophysically by previous investigators. Therefore, the pattern-onset wave seems to be a pattern-evoked response. The amplitude of the b-wave following pattern offset showed a monotonic decrease with increasing spatial frequency. It is mainly a luminance-evoked response. Under low retinal illumination (457 photopic td) the pattern-onset wave and the b-wave at pattern offset were smaller. However, the pattern-onset wave had its maximum amplitude at a lower spatial frequency. When increases or decreases in space-average luminance were combined with pattern onset or offset, transitions between pattern- and luminance-evoked responses could be observed. The results suggest that a decrease in local luminance is the essential stimulus for evoking a pattern-related response while increases in local light intensity generate luminance-evoked responses.
Conservation agriculture: growing more with less - the future of sustainable intensification. (2016)

This chapter looks at the most common and most important limiting factors to farm productivity in African agriculture and examines whether conservation agriculture (CA) can increase the efficiency of their use. It is concluded that CA is not a low-input system (although it can be a low external input system), and therefore 'growing more for less' is unlikely, especially in situations, such as those of many of the smallholder farms in sub-Saharan Africa, where farmers currently apply very low levels of inputs. The benefits of CA lie rather in using applied inputs (nutrients, water, labour, fuel) more efficiently than conventionally tilled systems, while at the same time reversing the soil degradation caused by tillage.
Mesh Architecture for Efficient Integrated Access and Backhaul Networking (2020)

Integrated access and backhaul (IAB) networking is envisioned as a key technology to support more flexible and dense deployment of base stations (BSs). However, existing directed acyclic graph (DAG) based IAB networking highly limits the flexibility and efficiency of link scheduling, due to the fixed parent-to-child relation between two adjacent IAB nodes. In this paper, a mesh-architecture based approach is developed to improve the efficiency of IAB networking. The key idea of the mesh architecture is to make the relationship between two adjacent IAB nodes configurable. Based on the mesh architecture, the two-stage scheduling scheme of IAB networks is revised. The typical scenarios where the mesh-architecture based IAB networking outperforms the DAG-based one are analyzed. Simulation results show that the mesh-architecture based IAB networking can effectively improve the throughput by 6.70%40.56% and substantially reduce the delay under various traffic loads, as compared to the DAG-based IAB networking.
