Surface Energies Control the Self-Organization of Oriented In<sub>2</sub>O<sub>3</sub> Nanostructures on Cubic Zirconia (2010)

Highly aligned one-dimensional (1D) nanorods of the transparent conducting oxide In(2)O(3) have been grown on (110)-oriented Y-stabilized ZrO(2) substrates, whereas growth on (100) and (111) substrates leads respectively to blocklike 3D islands and continuous films. It is shown that the striking influence of substrate orientation on the growth morphology is controlled by differences in energies between the low index surfaces of In(2)O(3) and that spontaneous self-organization is driven by minimization of surface energies.
고혈압 환자에서 발행할 수 있는 수술중 및 수술후의 심혈관계 변화에 대한 고찰 (1991)

Hypetension is the most common cause of heart failure and left ventricular hypertrophy. Recently, with advances in operating techniques, equipment and anaesthesiology, elderly patients have had more chances to undergo operation. Therefore, chances for patients with hypertension that comprise 15%-20% of the adult population in Korea to undergo operation has become more frequent. To evaluate the frequency and pragnosis of the cardiovascular changes in patients with hypertension during operation and the perioperative period, the blood pressures of 100 patients who underwent operation at Seoul Paik Hospital from September 1988 to October 1990 were measured proeoperatively, during operation, and postoperatively and analyzed in relevance to cardiovascular complications. The cardiovascular complications were divided into 4 categories: 1) Increase in systolic blood pressure 2) Decrease in systolic blood pressure 3) Marked changes in systolic blood pressure 4) Others (arrythmias, heart failure, chest pain) The results were as follows: 1) Episodes of an increase in the systolic blood pressure more than 50 mmHg compared to the systolic blood pressure at the time of consultation were found in 7 cases (7%) 2) Episodes of a decrease in systolic blood pressure below 100 mmHg were detected in 8 cases (8%) and in most cases, the blood pressure was corrected to normal level simply by the rapid infusion of fluid, except for 1 case that required the use of ephedrine or clacium gluconates. 3) Episodes of changes in systolic blood pressure more than 50 mmHg were found in 42 cases (42%). 4) There were 5 episodes of ventricular premature beat or atrial premature beat, but they were corrected to normal sinus rhythm by intravenous lidocain injection, and there were no more problems postoperatively. 5) There were no coronary events or heart failures clinically. 6) It seemed that there was no correlation between the level of preoperative blood pressure and frequency of cardiovascular complications, In conclusion, most of the patients with hypertension corrected preoperatively or not underwent operation successfully without any cardiovascular complications if the anaesthesiologist monitored the blood pressure and took appropriate therapeutic measures predperatively.
Agent-based simulation for large-scale emergency response (2012)

When attempting to determine how to respond optimally to a large-scale emergency, the ability to predict the consequences of certain courses of action in silico is of great utility. Agent-based simulations (ABSs) have become the de facto tool for this purpose; however, they may be used and implemented in a variety of ways. This article reviews existing implementations of ABSs for large-scale emergency response, and presents a taxonomy classifying them by usage. Opportunities for improving ABS for large-scale emergency response are identified.
Analysis of the Nyquist Folding Receiver (NYFR) (2018)

Increased utilization of the radio frequency spectrum motivates receivers with wide instantaneous bandwidth for applications such as signals intelligence, cognitive radio, and compliance testing. Traditional wideband receivers inherently have high data rates that are difficult to process and store, and receivers that use multiple analog to digital converters to achieve wide bandwidth have high power usage and cost. Compressive sensing (CS) provides a potential low-data-rate and low-power solution in environments where only a small portion of the wide spectrum monitored is in use at one time, through sub-Nyquist sampling at the information rate. The Nyquist Folding Receiver (NYFR), proposed by Fudge et al., is one such promising CS architecture. The NYFR significantly undersamples input signals causing them to alias such that original frequencies would normally be lost, but the NYFR encodes the original frequency as modulation on the input signals so that all of the original information is preserved. This thesis adds a model of a real-valued NYFR, and uses the model to investigate the design trade-offs inherent to any NYFR receiver. Basic applications including pulse detection, angle of arrival estimation (DoA), and processing of communication signals are simulated. Finally, a prototype receiver was used to experimentally demonstrate the capabilities of a NYFR with an instantaneous bandwidth of 18 GHz while only sampling at 1.5 GSPS.

ITO@Cu<sub>2</sub>S Tunnel Junction Nanowire Arrays as Efficient Counter Electrode for Quantum-Dot-Sensitized Solar Cells (2013)

Quantum-dot-sensitized solar cell (QDSSC) has been considered as an alternative to new generation photovoltaics, but it still presents very low power conversion efficiency. Besides the continuous effort on improving photoanodes and electrolytes, the focused investigation on charge transfer at interfaces and the rational design for counter electrodes (CEs) are recently receiving much attention. Herein, core-shell nanowire arrays with tin-doped indium oxide (ITO) nanowire core and Cu2S nanocrystal shell (ITO@Cu2S) were dedicatedly designed and fabricated as new efficient CEs for QDSSCs in order to improve charge collection and transport and to avoid the intrinsic issue of copper dissolution in popular and most efficient Cu/Cu2S CEs. The high-quality tunnel junctions formed between n-type ITO nanowires and p-type Cu2S nanocrystals led to the considerable decrease in sheet resistance and charge transfer resistance and thus facilitated the electron transport during the operation of QDSSCs. The three-dimensional structure of nanowire arrays provided high surface area for more active catalytic sites and easy accessibility for an electrolyte. As a result, the power conversion efficiency of QDSSCs with the designed ITO@Cu2S CEs increased by 84.5 and 33.5% compared to that with planar Au and Cu2S CEs, respectively.

Kansas Academy of Science 1949: Man's Disorder of Nature's Design in the Great Plains (1949)

Coast immediately began to clear the ground for cultivation, and as population moved westward, the practice of cultivating the soil moved likewise. It took many years, however, to reach the high plains of western Kansas. Wheat production seemed not to reach its maximum relative importance as a farm crop in the United States until it was grown on soils formerly occupied by prairie vegetation. This crop provided an ever increasing supply of wheat flour for making bread but Man does not live by bread alone--he needs a beefsteak occasionally. If man today were like Nebuchadnezzar of old, it would not be necessary for him to obtain by proxy his share of the vast amount of energy produced in the vegetation of our grasslands (Sampson, 1932). We have advanced beyond the stage of our ancient forefathers, DR. F. W. ALBERTSON
Circulating Soluble Neuropilin-1 in Patients with Early Cervical Cancer and Cervical Intraepithelial Neoplasia Can Be Used as a Valuable Diagnostic Biomarker (2015)

sNRP-1 in circulating can serve as a possible valuable diagnostic biomarker for cervical cancer and CIN.
On Sets of Consistent Arcs in a Tournament (1965)

A (round-robin) tournament T n consists n of nodes u 1 , u 2 , …, u n such that each pair of distinct nodes u i and u j is joined by one of the (oriented) arcs or The arcs in some set S are said to be consistent if it is possible to relabel the nodes of the tournament in such a way that if the arc is in S then i>j. (This is easily seen to be equivalent to requiring that the tournament contains no oriented cycles composed entirely of arcs of S.) Sets of consistent arcs are of interest, for example, when the tournament represents the outcome of a paired-comparison experiment [1]. The object in this note is to obtain bounds for f(n), the greatest integer k such that every tournament T n contains a set of k consistent arcs.
Stereospecific hydration of unsaturated fatty acids by bacteria (1971)

Abstract Three new 10‐hydroxy fatty acids, all optically active, have been prepared by the anaerobic microbiological hydration of a cis ‐9 double bond. Substrates that formed these new hydroxy fatty acids are linoleic, linolenic, and ricinoleic acids. The hydroxyl group has the D configuration and the methyl esters are levorotatory. Infrared, mass spectral, specific rotation and ultraviolet data on these compounds were determined. There was no migration of the unreated double bonds at C 12 and C 15 in linoleic or linolenic acids. The presence of a double bond in the 10‐hydroxy fatty acids significantly increased the optical rotation of the methyl esters. The hydratase enzyme showed unusual specificity among Δ 9 unsaturated acids. While it hydrates methylene interrupted and hydroxy unsaturated acids, it failed to hydrate either 9‐decenoic, 12,13‐epoxy‐ or 12‐keto‐ cis ‐9‐octadecenoic acids or sterculic acid.
The Survival of Monolayers of Cells Growing in Clusters Irradiated by 211 At Appended to the Cell Surfaces (1999)

A model of cell survival is described for the case of closely packed clusters of cells growing in monolayers. For alpha-particle decays on the cell surfaces, it is shown that cross-firing between cells produces nonuniform dose distributions within the cluster and that cells in larger clusters are exposed on average to greater doses. The model is used to simulate the survival of SK-MEL-28 human melanoma cells labeled with different radiolabeled monoclonal antibodies. The survival data suggest that this cell line is more sensitive to high-LET radiation than previously thought.
Source location from time differences of arrival: Identifiability and estimation (2005)

A new framework is presented for the problem of estimating source location from a set of time difference of arrival (TDOA) measurements. First the conditions under which the source coordinates are identifiable are derived and geometrically interpreted. Then it is shown that the source location can be found, when it is identifiable, by estimating the coefficients of a set of linear relationships, with the number of equations being equal to the number of stations.
Interfacing internet of things technologies of RFID, XMPP and Twitter to reduce inaccuracies in inventory management (2012)

A critical issue in inventory management is having accurate and timely information on stock levels. Stock-out often occurs in the retail industry due to human errors, theft, or product counterfeiting. Counterfeit products, expired products, and misplacement of products pose a challenge in inventory management. Therefore, advantage should be taken of technologies that can reduce the impact of counterfeits, expired products, and misplaced products. One such group of technologies is the Internet of Things (IoT). This study develops an architecture that uses IoT technologies as enablers for detecting expired products, counterfeit products, stock levels, and misplaced products for inventory management in retail enterprises. The proposed model uses extensible messaging presence protocol (XMPP), radio frequency identification (RFID) to provide a communication mechanism between the inventory manager, inventory processes and the users. Twitter is central to providing feedback to the relevant user on the state of the inventory, while radio RFID technology is used in detecting the products. The Twitter service is provided via Beachcomber. General Terms Design
Enhancing the spatial resolution of a two-dimensional discrete array detector (1999)

We present a technique for enhancing the resolution of a twodimensional detector by processing images that have been subsequently acquired shifted by a fraction of a pixel with respect to each other. Possible limitations due to the intrinsic spectral broadening of the actual signals and to sources of error in the procedure have been analyzed. The results prove that the reconstruction algorithm is insensitive to high uncertainties in the relative subpixel displacements of the single images and to a low signal-to-noise ratio. Experimental tests have been performed with a detector with pixel size 25x25 ?m2. Images of fine wire mesh grids with periods 100 and 50 ?m and of a 10-?m-wide slit are presented. The reconstructed images show improved resolution of the profiles of the targets corresponding to 1/4-pixel sampling.
Thermal Swing Adsorption Process for Carbon Dioxide Capture and Recovery: Modeling, Simulation, Parameters Estimability, and Identification (2013)

In one of our previous studies, several experimental measurements were carried out on a thermal swing adsorption (TSA) process (adsorption and desorption steps) used for the capture of CO2 from a CO2/N2 mixture. The present study deals with a two-dimensional modeling and simulation of the aforementioned TSA process. The models are described by partial differential equations (PDEs) including conservation equations, models for equation of state, equilibrium, thermodynamic, and transport properties. The resulting models involve different unknown parameters to be estimated from the available experimental measurements. An estimability analysis was carried out in order to determine which parameters are able to be estimated from the available experimental results. The most estimable parameters are then identified, and the less estimable parameters are fixed from previous works or from literature. The resulting models are implemented and solved within Comsol Multiphysics software. The results show that the model predictions fit quite well with the experimental results.
Trends in Counter-Current Chromatography: Applications to Natural Products Purification (2010)

Counter-current chromatography (CCC), a unique continuous liquid-liquid partition chromatographic technique, has been widely used in the separation and purification of natural products. This technique has made great progress in recent years. In this paper, the different possible separation methods developed in CCC are described. It includes classical CCC, pH-zone-refining, pH-gradient, ion-pairing, multi-channel and two-dimensional CCC, dual-flow, liquid-liquid-liquid three-phase systems, elution-extrusion, gradient elution, powder direct injection, with some words for the various techniques used in pre- and post-CCC procedures, and detection modes. The basic mechanisms of each method are presented and applications are summarized. The future of CCC developments, including its application in protein purification and enrichment, and new platforms, are also discussed. This review paper aims to aid scientists who are interested in the field of CCC research for natural product isolation.
Deployment of quasi-digital sensor for high temperature molten salt level measurement in pyroprocessing plants (2018)

Development of a liquid molten salt level sensor device that can detect the level of liquid molten salt in the process vessels of pyrochemical reprocessing of spent metallic fuels is detailed. It is proposed to apply a resistive-type pulsating sensor-based level measurement approach. There are no commercially available sensors due to limitations of high temperature, radiation, and physical dimensions. A compact, simple, rugged, low power, and high precise pulsating sensor-based level probe and simple instrumentation for the molten salt liquid level sensor to work in the extreme conditions has been indigenously developed, with high precision and accuracy. The working principle, design concept, and results have been discussed. This level probe is mainly composed of the variable resistor made up of ceramic rods. This resistor constitutes the part of resistance-capacitance-type Logic Gate Oscillator (LGO). A change in the molten salt level inside the tank causes a small change in the resistance which in turn changes the pulse frequency of the LGO. Thus the frequency, the output of the instrument that is displayed on the LCD of an embedded system, is a function of molten salt level. In the present design, the range of level measurement is about 10 mm. The sensitivity in position measurement up to 10 mm is ∼2.5 kHz/mm.

[Free-radical processes and blood antioxidant systems in the late period following acute radiation sickness]. (1991)

Some indices of free radical processes and antioxidant blood protection systems were investigated in a group of persons exposed to ionizing radiation at the Chernobyl accident. Lipid peroxidation was shown to undergo changes against a background of decreased antiperoxide protection of erythrocytes 22-24 mos. after exposure in patients after acute radiation sickness, I degree. As compared to donors, the examinees demonstrated a tendency to the accumulation of primary products of lipid peroxidation--hydroperoxides (by 32.2%) and a significant decrease in erythrocyte peroxide stability.
Apoptosis of medulloblastoma cellsIn vitro follows inhibition of farnesylation using manumycin A (1999)

Medulloblastoma is a malignant cerebellar tumor usually manifesting in childhood. We have previously shown that blocking the mevalonate pathway with lovastatin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, inhibits medulloblastoma proliferation and induces apoptosis in vitro. The underlying mechanism may involve blocking post-translational modification of important mitogenic signal-transduction proteins. We show that p21 ras processing is blocked by lovastatin, suggesting that inhibition of isoprenylation may be important in lovastatin-induced apoptosis. To test this hypothesis, manumycin A, an antibiotic which inhibits farnesyl protein transferase and thus farnesylation, was administered to 4 medulloblastoma cell lines in vitro. We found that blocking protein farnesylation with manumycin A was followed by apoptosis in a time- and dose-dependent manner. However, cell death induced by manumycin A was uniformly more rapid and efficient, requiring only 12 to 24 hr of treatment, than lovastatin-induced apoptosis, which required 36 to 96 hr (depending on the cell line tested). In addition, unlike lovastatin, which caused cell-cycle arrest in G1 phase and HMG-CoA reductase gene up-regulation, manumycin A had no effect on the cell cycle and resulted in down-regulation of HMG-CoA reductase gene expression. In both lovastatin- and manumycin A-treated cells, cellular cysteine protease precursor (CPP32) was activated, confirming the occurrence of apoptosis.
Rapid accurate point-of-care tests combining diagnostics and antimicrobial resistance prediction for<i>Neisseria gonorrhoeae</i>and<i>Mycoplasma genitalium</i> (2017)

In addition to inadequate access to early diagnosis and treatment with antimicrobial agents for patients and sexual contacts, management and control of STIs is significantly challenged by emergence and spread of antimicrobial resistance (AMR), particularly for STIs such as <i>Neisseria gonorrhoeae</i> and <i>Mycoplasma genitalium</i> This is further compounded by use of nucleic acid amplification techniques for diagnosis, resulting in reduced phenotypic AMR testing for <i>N. gonorrhoeae</i> and absence or suboptimal AMR surveillance for guiding treatment of both STIs in many settings. Rapid accurate point-of-care (POC) tests for diagnosis of all STIs would be valuable but to significantly impact treatment precision and management of <i>N. gonorrhoeae</i> and <i>M. genitalium</i> infections, combinations of rapid POC diagnostic and AMR testing (POC-AMR) will likely be required. This strategy would combat STI burden and AMR emergence and spread by enabling diagnosis and individualised treatment at the first healthcare visit, potentially reducing selection pressure on recommended antimicrobials, reducing transmission of resistant strains and providing means for AMR surveillance. Microfluidic and nanotechnology platforms under development for rapid detection of STIs provide a basis to also develop molecular rapid POC-AMR prediction. A number of prototypic devices are in the pipeline but none as yet approved for routine use. However, particularly for <i>N. gonorrhoeae</i>, more knowledge is required to assess which antimicrobials lend themselves to a genotypic POC-AMR approach, in relation to genotypic-phenotypic associations and potential impact clinically and epidemiologically. Key for successful deployment will include also understanding cost-effectiveness, cost-consequences and acceptability for key stakeholders.
