<title>Contrast enhancement of missile data through image sequence stabilization and product correlation</title> (1994)

Missile image sequences often contain a strong plume signature expelled by the missile, with a weak signal corresponding to the missile hardbody. Enhancement of the missile signal in low signal-to-noise ratio environments is necessary to accurately track the trajectory throughout the sequence. By stabilizing the image sequence a registered data set is produced in which the missile hardbody can be found in the same location within each frame. A statistical method known as product correlation (PC) may be applied to the stabilized data, enhancing missile contrast with respect to the background. An algorithm for the passive stabilization of video sequences consisting of missile imagery is described. PC is presented in the context of higher order statistics and then applied to stabilized video sequences to enhance the missile hardbody signal within the data.
Fast presurgical functional mapping using task-related intracranial high gamma activity (2013)

General linear model-based ECoG mapping showed a superior performance compared to traditional ECS and fMRI mapping in terms of efficiency and accuracy. Using this method, motor functions can be reliably mapped in less than 5 minutes.
Synthesis of poly‐β‐(α‐benzyl‐L‐aspartate) from L‐aspartic β‐lactam benzyl ester (3(R)‐benzoxycarbonyl‐2‐azetidinone) (1986)

Abstract A study on the anionic‐assisted polymerization of L‐aspartic β‐lactam benzyl ester in solution has been carried out in order to prepare an improved poly‐β‐(α‐benzyl‐L‐aspartate). We have found that both imide formation (with appreciable racemization) and size of the resulting polymers are highly dependent on the nature of reaction medium. A high molecular weight poly‐β‐aspartate without detectable branching could thus be obtained by using solvents with low polarity. The mechanism of side reactions is discussed.

Multiple scattering of 5-30 keV electrons in evaporated metal films: I. Total transmission and angular distribution (1964)

The total fraction of the current transmitted and its angular distribution have been measured when an electron beam is incident normally on evaporated films of aluminium, copper, silver and gold. The range of mass-thickness ρx investigated was such that plural scattering prevailed in the thinnest, and diffusion conditions in the thickest films. The energy of the incident beam was varied between 5 and 30 keV. The experimental results are not explained in quantitative detail by any of the existing theories.
Hybrid integration of semiconductor lasers with Si-based single-mode ridge waveguides (1992)

Hybridization is a convenient way for providing silicon-based integrated optical circuits with a laser source. An entirely passive alignment technique exclusively based on the high precision obtainable by lithography and by semiconductor processes was examined. A novel way of cleaving the laser chips by self-aligned cleaving grooves was employed. It resulted in 15.5-dB coupling losses between the laser diode and the single-mode buried ridge waveguide.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Device Performance of Heterojunction Tunneling Field-Effect Transistors Based on Transition Metal Dichalcogenide Monolayer (2013)

The ballistic device performances of monolayer transition metal dichalcogenide (MX2) tunneling field-effect transistors (TFETs) and the drive current enhancement via heterojunction are investigated in this letter via the nonequilibrium Green's function formulism. The ultrathin 2-D body and the direct and designable bandgap by choosing a proper MX2 material are advantageous for the performance of TFETs. Through introducing a common- X heterojunction at the source-channel interface, the I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ON</sub> at the same I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ON</sub> /I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OFF</sub> ratio can be further enhanced by an order for both n- and p-type TFETs.
Effects of Delayed Rectifier Current Blockade by E-4031 on Impulse Generation in Single Sinoatrial Nodal Myocytes of the Rabbit (1995)

The role of the delayed rectifier current (IK) in impulse generation was studied in single sinoatrial nodal myocytes of the rabbit. We used the class III antiarrhythmic drug E-4031, which blocks IK in rabbit ventricular myocytes. In single sinoatrial nodal cells, E-4031 (0.1 mumol/L) significantly prolonged cycle length and action potential duration, depolarized maximum diastolic potential, and reduced both the upstroke velocity of the action potential and the diastolic depolarization rate. Half of the cells were arrested completely. At higher concentrations (1 and 10 mumol/L), spontaneous activity ceased in all cells. Three ionic currents fundamental for pacemaking, ie, IK, the long-lasting inward calcium current (ICa,L), and the hyperpolarization-activated current (I(f)), were studied by using the whole-cell and amphotericin-perforated patch technique. E-4031 blocked part of the outward current during depolarizing steps as well as the tail current upon subsequent repolarization (ITD) in a dose-dependent manner. E-4031 (10 mumol/L) depressed ITD (88 +/- 4%) (n = 6), reduced peak ICa,L at 0 mV (29 +/- 15%) (n = 4), but did not affect I(f). Lower concentrations did not affect ICa,L. Additional use of 5 mumol/L nifedipine demonstrated that ITD is carried in part by a calcium-sensitive current. Interestingly, complete blockade of IK and ICa,L unmasked the presence of a background current component with a reversal potential of -32 +/- 5.4 mV (n = 8) and a conductance of 39.5 +/- 5.6 pS/pF, which therefore can contribute both to the initial part of repolarization and to full diastolic depolarization.(ABSTRACT TRUNCATED AT 250 WORDS)
Expression of PARP in lung cancer: Patients with COPD and mice (2019)

Lung cancer (LC) is a leading cause of cancer death worldwide. COPD is an independent risk factor for LC. Poly-ADP ribose polymerase (PARP)-1 and PARP-2 play crucial roles in DNA repair and cancer. Hypothesis: Expression of PARP-1 and PARP-2 may differ in tumors of LC patients with/without COPD and in mice (compared to non-tumor lungs) with experimental adenocarcinoma. Patients: Lung tumor and non-tumor specimens (thoracotomy) were obtained from LC patients with/ without COPD (two patient groups, N=9/group). Mice: Lung tumors (LP07 adenocarcinoma cells, 1 month) were harvested from lungs of wild-type BALB/C mice and non-tumor control mice were also studied (N=9/group). PARP-1 and PARP-2 expressions were determined in lung tumors and non-tumor samples from both human and mouse studies (immunoblotting). Patients: No significant differences were seen in PARP-1 protein levels between tumor and non-tumor samples in either LC or LC-COPD patients. However, a significant decline in PARP-2 protein levels were detected in tumors of both LC and LC-COPD patients, especially in the latter group, compared to non-tumor lung samples. Mice: whereas PARP-1 expression was significantly lower in mouse tumors than in non-tumor specimens, PARP-2 did not significantly differ between lung tumor and non-tumor control samples. There was a differential expression profile of PARP-1 and PARP-2 isoforms in lung tumors of the patients. In mice, PARP-1 and PARP-2 were also differentially regulated in lung tumors. These results suggest that PARP-1 and PARP-2 may play different roles in lung cancer in mice and humans. <b>Funded by:</b> CIBERES, FIS 14/00713 & FIS 18/00075 (FEDER), SEPAR 2016 & 2018, FUCAP 2016, and unrestricted grant from Menarini SA 2018.
Onomatopoeic <i>Mimesis</i> in Plato, <i>Republic</i> 396b–397c (1973)

Two related passages in the discussion of mimesis in this part of The Republic are in question here: Commentators and translators generally agree that Socrates is referring to the effect of imitations of such sounds in performances of drama or dithyramb, and that the mimesis in question is the result of ‘identification’ on the part of spectators. As Adam puts it: ‘In good acting the spectator identifies himself with the actor through sympathy; and as the actor “imitates” so does he.’ Since several of the sounds mentioned would be difficult to imitate effectively by the human voice, Adam and others suggest that the imitative sounds were produced by musical effects and stage-machines (such as the βροντϵȋον ). They note that the later ‘degenerate’ dithyrambic performances aimed at mimetic effects of this kind; and so too, of course, did Old Comedy. The three main points in this generally accepted interpretation are: ( a ) the mimesis mentioned here is largely a matter of musical reproduction of the sounds listed; ( b ) the mimesis consists of direct mimicry of these sounds; ( c ) Socrates is referring to dramatic and dithyrambic performances. There are objections to all of these points. First, against the notion that musical mimesis is primarily or mainly intended: up to this point in the discussion Socrates has confined his remarks to literature. He concludes his literary discussion quite specifically in 398b: ‘Now it looks as if we have completed our survey of the words and myths of μουσική.’ Then he explicitly goes on to consider ‘after this’ the remaining matter, namely, the right kind of ᾠδή and μέλος for the education of the Guardians.
A noncontact permanent magnet levitation table with electromagnetic control and its vibration isolation method using direct disturbance cancellation combining optimal regulators (1995)

A vibration isolation table levitating without contacts by drag-force type electromagnetic actuators is presented. The actuator consists of a permanent magnet connected to an electromagnet. The gravity force of the table is suspended by permanent magnets, and vibrations due to disturbances are controlled by changing magnetic fluxes of the permanent magnets. When the horizontal disturbance applies to the magnetic levitation supports of the table, the location of the magnets moves from the set position. This implies that the magnetic forces in both the horizontal and vertical directions vary due to base disturbances. An analysis of the magnetic levitation force, magnetic stiffness, and control force, is presented first and then a method of vibration control is presented. The control method is based on a disturbance cancellation combining an optimal regulator with consideration of interferences of the magnetic forces between horizontal and vertical motions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Porous Polymer Optical Fiber For Carbon Monoxide Detection (1990)

A carbon monoxide fiber optic probe has been developed with a porous polymer optical fiber. The carbon monoxide sensing reagent is palladious chloride which was dissolved in the monomer solution before forming the porous polymer fiber. Other than the high sensitivity, the porous polymer fiber, made by heterogeneous crosslinking polymerization, exhibits very high gas permeability and liquid impermeability. The trapped indicator is very stable to atmosphere and enables this optical fiber probe to be used as a "chemfuse" for a carbon monoxide warning system. The porous sensing segment can be attached to regular waveguides by fiber optic couplings, therefore, it can be easily replaced. A linear response of this probe was observed for 1% to 100% of carbon monoxide in air. The temperature effect and interference from other gases with this probe have been investigated.
Mossfloran i Stenshuvuds Nationalpark – 81 år efter Herman Persson (2015)

The bryophytes of the Stenshuvud National park, situated on the east coast of the province of Skåne, southern-most Sweden, was thoroughly investigated in 2015 by a team of 16 bryologists. In total, 204 taxa were found, including 5 nationally red-listed taxa. Most surprisingly, Dichelyma capillaceum was found in a small pond far outside its known distribution by the river Helgeå in northern Skåne. We found almost exactly as many taxa in 2015 as there are records from the literature and herbaria from the period 1850–1945, including those of Herman Persson’s inventory of parts of the area in the 1930’s. However, as compared to the period 1850–1945, 57 taxa were found anew while 60 taxa were not refound. If the groups of new and not refound taxa are compared with respect to their Ellenberg Indicator Values, the new taxa on average have significantly higher temperature demands and demand higher substrate-pH.
Synthesis of Resorcinols via a Michael Addition-Dieckman Cyclization Sequence of Dimethyl 1,3-Acetonedicarboxylate Anion with Alkyl Alkynoates (1998)

Abstract The reaction of dimethyl 1,3-acetonedicarboxylate anion 1 with a number of alkyl alkynoates gives unsymmetrical (from alkynoates 2a-g) or symmetrical (from alkynoates 2h-i) resorcinols, in a one pot synthesis.
A thermostat for light scattering measurements (1954)

Abstract A thermostat for light scattering studies is described in which the glass cell containing the solution under investigation is immersed in water maintained at constant temperature. The construction is such that the phototube used for detection of scattered light is at room temperature whatever the temperature of the sample. The liquid bath about the sample cell minimizes both troublesome reflections of the incident light and errors arising from refraction effects.
Misunderstood or Overlooked Gas-Lift Design and Equipment Considerations (1994)

Abstract Gas-lift (GL) installation design calculations and examples are presented in GL manuals, text books and other publications. Example calculations range from very simplified to detailed designs requiring accurate well information and gas-rate throughput performance for the gas-lift valves (GLV's). Unfortunately, the actual GL installation does not always operate as predicted. Certain wells will require more injection gas and produce less fluid than the other wells in the same injection-gas system. The poorer performing wells have the same fluid properties and may have similar or better productivity characteristics. The objective of this paper is to discuss several design and operating procedures that can prevent unloading a well, lead to heading and surging, and other considerations that cause excessive injection-gas usage and lower than predicted production rates.

Pervasive Computing in the Supermarket (2010)

Shopping in the real world is becoming an increasingly interactive experience as stores integrate various technologies to support shoppers. Based on an empirical study of supermarket shoppers, the authors designed a mobile context-aware system called the Context-Aware Shopping Trolley (CAST). The purpose of CAST is to support shopping in supermarkets through context-awareness and acquiring user attention, thus, the authors’ interactive trolley guides and directs shoppers in the handling and finding of groceries. An empirical evaluation showed that shoppers using CAST behaved differently than shoppers using a traditional trolley. Specifically, shoppers using CAST exhibited a more uniform pattern of product collection and found products more easily while travelling a shorter distance. As such, the study finds that CAST supported the supermarket shopping activity.
Oxidative stress enhanced the transforming growth factor-β2-induced epithelial-mesenchymal transition through chemokine ligand 1 on ARPE-19 cell (2020)

Fibroblast-like transformation of retinal pigment epithelial (RPE) cells is a pathological feature of proliferative vitreoretinopathy (PVR) that may cause blindness. The effect of oxidative stress alone or together with transforming growth factor-beta 2 (TGF-β2) on epithelial-mesenchymal transformation (EMT) is not fully understood in RPE. TGF-β2 induced the upregulation EMT markers including α-smooth muscle actin (α-SMA), Snail, and Slug and downregulation of E-cadherin (E-cad) in ARPE-19 cells. Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) not only upregulated α-SMA but also enhanced the effect of TGF-β2 on the expression of Snail and Slug. The CXCL family of cytokines could be the mediators of EMT induced by H<sub>2</sub>O<sub>2</sub> and TGF-β2. H<sub>2</sub>O<sub>2</sub> induced CXCL1, that upregulated α-SMA and fibronectin. Both SB225002, an inhibitor of CXCR2, and antioxidant N-acetylcysteine suppressed the TGF-β2-induced EMT in ARPE-19 cells. Taken together, the results suggest that oxidative stress enhanced TGF-β2-induced EMT through the possible autocrine effect of CXCL1 on CXCR2 in ARPE-19 cells.
Practical Results of a Five-level Flying Capacitor Inverter (2010)

This paper investigates the realization of a five-level Flying Capacitor Inverter. After a brief description of general Power Electronic Converters and an introduction to the advantages of Multilevel Inverters over conventional two-level Inverters the main focus is on the five-level Flying Capacitor Inverter. The Flying Capacitor Multilevel Inverter (FCMI) is a Multilevel Inverter (MI) where the capacitor voltage can be balanced using only a control strategy for any number of levels. After a general description of five-level FCMI topology, the simulation and experimental results are presented. The capacitor voltage is stabilized here with various output voltage amplitude values. The simulation and experimental results of five-level FCMI show that the voltage is stabilized on capacitors using the control strategy. A single-phase five-level FCMI model is currently being developed and constructed in the laboratory. Some of the experimental results are available.
DCO networking solutions to the provision of advanced features in rural and suburban telephone networks (2003)

The authors describe the evolution of the Stromberg-Carlson DCO (digital central office) networking capabilities to support ISDN (integrated services digital network) and IN/2 (Intelligent Network/2) services. The various components of the DCO family can be formed into a network cluster which allows one switch to act as a control point or host. This host acts as a transfer point for SS7 (Signaling System 7) messages and a control point for calls requiring special routing. The network cluster can connect to STPs (signaling transfer points) associated with the national network by means of one pair of signaling links, regardless of the number of switching elements in the network. This allows the telephone company to provide ISDN and intelligent network features to all subscribers within the network cluster with reduced operating costs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Estimation of noise in ECG signals using wavelets (2008)

ECG signal and generally biomedical signals change their statistical properties over time. The most powerful tool for analyzing non-stationary signals is the wavelet transform. We developed and evaluated a noise perturbing ECG detection system based on the multi-resolution analysis. We considered four types of ECG signal, without additional noise and corrupted by three types of noise and we realized the signals classification using wavelet filtering and statistical analyses. The ECG data is taken from the standard MIT-BIH Arrhythmia database, while the signals of noise belong to MIT-BIH Noise Stress Test Database.
