Lock-in technique for concurrent measurement of adhesion and friction with the scanning force microscope (2001)

Regardless of all the great progress in new scanning probe microscopy techniques, the concurrent measurement of adhesive and frictional forces with local resolution using scanning force microscopy (SFM) has not been possible until now. In this paper, we present a novel scanning probe microscopy mode, called combined dynamic x mode or CODYMode®. In CODYMode® SFM at least two oscillations with sufficiently different frequencies and amplitudes are superimposed and interact with the sample surface. This enables the concurrent measurement of the topography, adhesive and frictional forces beside further mechanical surface properties of the sample. By means of the characterization of plasma treated biaxially oriented polypropylene foils the benefits of the new modulation technique are pointed out where common SFM techniques are not adequate. As second application high-velocity friction experiments (in the range of several centimeters per second) on silicon under controlled environmental conditions are introduced and the role of the native water film on it is discussed under friction and viscoelastic aspects.
The characterization of a newly identified, highly metastatic variety of Dunning R 3327 rat prostatic adenocarcinoma system: the MAT LyLu tumor. (1981)

The Dunning R 3327 AT tumor is a rapidly growing, androgen insensitive, serially transplantable rat tumor of prostatic origin. In early passages, the AT tumor had a very low rate of distant metastases (less than 1 per cent); however, after 60 serial subcutaneous passages, the AT tumor has given rise to a new tumor line which has an extremely high metastatic rate. Greater then 75 per cent of all animals inoculated with this late passage tumor develop lymph node metastases alone or in combination with lung metastases. This high passage tumor seems to be distinct from the original AT tumor since it has a substantially faster doubling time and a massively increased metastatic potential; it has therefore been named the Dunning R 3327 MAT LyLu tumor (metastatic AT tumor able to disseminate to lymph nodes and lung). The MAT LyLu tumor, like the parent nonmetastatic AT tumor, is androgen insensitive with regard to its growth rate, rate of distant metastases and mean survival time. This newly characterized MAT LyLu tumor provides an appropriate animal model system for testing the potential effectiveness of a variety of therapeutic approaches specifically aimed at limiting the metastatic spread of prostatic cancer.
Eidola: An Interactive Augmented Reality Audio-Game Prototype (2009)

Augmented reality audio represents a new trend in digital technology that enriches the real acoustic environment with synthesized sound produced by virtual sound objects. On the other hand, an audio-game is based only on audible feedback rather than on visual. In this work, an audio-game prototype is presented which takes advantage of the characteristics of augmented reality audio for realizing more complex audio-game scenarios. The prototype was realized as an audiovisual interactive installation, allowing the further involvement of the physical game space as the secondary component for constructing the game ambient environment. A sequence of tests has shown that the proposed prototype can efficiently support complex game scenarios provided that the necessary advanced interaction paths are available.

Trioxsalen bath plus UVA effective and safe in the treatment of psoriasis (1978)

Seventy‐four patients with psoriasis were treated using a trioxsalen bath (50 mg/150 1 of water) and long wave ultraviolet light (UVA) given in an ordinary PUVA‐cabin. Good or excellent results were observed in 92% of the patients in the initial phase and in 63% during the maintenance treatment. Because of local side‐effects the therapy was discontinued in two patients. One of them developed contact hypersensitivity to trioxsalen and the other developed blisters with such low doses of UVA that it was difficult to maintain the proper dose. The therapy was started with 0‐28 J/cm2 of UVA and after an average of 18 treatments, when the average dose was 1.70 J/cm2, the patients were moved to maintenance treatment which took place at 1‐4 week intervals. The therapy was well tolerated and cosmetically very acceptable. The final tan was even on all but the face, which remained untanned.
Developmental Mechanisms in Articular Cartilage Degradation in Osteoarthritis (2010)

Osteoarthritis is the most common arthritic condition, which involves progressive degeneration of articular cartilage. The most recent accomplishments have significantly advanced our understanding on the mechanisms of the disease development and progression. The most intriguing is the growing evidence indicating that extracellular matrix destruction in osteoarthritic articular cartilage resembles that in the hypertrophic zone of fetal growth plate during endochondral ossification. This suggests common regulatory mechanisms of matrix degradation in OA and in the development and can provide new approaches for the treatment of the disease by targeting reparation of chondrocyte phenotype.
Unexpected Direct Reduction Mechanism for Hydrogenation of Ketones Catalyzed by Iron PNP Pincer Complexes (2011)

The hydrogenation of ketones catalyzed by 2,6-bis(diisopropylphosphinomethyl)pyridine (PNP)-ligated iron pincer complexes was studied using the range-separated and dispersion-corrected ωB97X-D functional in conjunction with the all-electron 6-31++G(d,p) basis set. A validated structural model in which the experimental isopropyl groups were replaced with methyl groups was employed for the computational study. Using this simplified model, the calculated total free energy barrier of a previously postulated mechanism with the insertion of ketone into the Fe-H bond is far too high to account for the observed catalytic reaction. Calculation results reveal that the solvent alcohol is not only a stabilizer of the dearomatized intermediate but also more importantly an assistant catalyst for the formation of trans-(PNP)Fe(H)(2)(CO), the actual catalyst for hydrogenation of ketones. A direct reduction mechanism, which features the solvent-assisted formation of a trans dihydride complex trans-(PNP)Fe(H)(2)(CO), direct transfer of hydride to acetophenone from trans-(PNP)Fe(H)(2)(CO) for the formation of a hydrido alkoxo complex, and direct H(2) cleavage by hydrido alkoxo without the participation of the pincer ligand for the regeneration of trans-(PNP)Fe(H)(2)(CO), was predicted.
리플로우 솔더링시 솔더 / Cu 계면반응속도에 미치는 Cu- 첨가 솔더의 영향 (2000)

We have investigated the effects of Cu additions to pure Sn and eutectic Sn-Pb solders on the morphology and growth kinetics of the intermetatllics (Cu_6Sn_5) and on the consumption rate of Cu substrate during isothermal reflow soldering. The consumption rate of Cu substrate could be reduced with increasing Cu content in both Sn and Sn-Pb solders up to the respective solubilities at reflow temperatures. The effect of Cu addition was more significant for the Sn solder which had a higher Cu solubility. The Cu addition also resulted in morphological changes of the intermetallic layer. With increasing Cu content, the interface between Cu_6Sn_5 layer and solder roughened for pure Sn solder whereas it flattened fur the eutectic Sn-Pb solder. When the time(t) dependence of the intermatallic layer thickness(X￣) was modelled as X￣ = a×t^n, the growth constant a appeared to increase with the Cu content whereas the growth exponent n decreased. It was shown that the growth kinetics of the intermetallic layer could be well interpreted by a model of grain boundary diffusion controlled growth.
Bone marrow stromal stem cells for tissue engineering (2006)

Although preliminary results have been achieved on many different fronts in applying BMSSC technology to tissue engineering, a tremendous amount of work still confronts researchers in this area. Whilst it is clear that BMSSC-mediated osteogenesis has the capacity to integrate with pre-existing bone tissue, substantial progress in this and other approaches needs to be achieved for the accurate reassembly of functional complex organ systems. Some of the main issues are identification of the optimal precursor cell types, establishment of growth and differentiation conditions that meet safety and good manufacturing practice standards, and manipulation of the surrounding environment to allow transplanted cells to survive and function. Furthermore, parallel progress in the development of novel gene manipulation technologies and inductive biocompatible scaffold/material designs are equally as vital. It is anticipated that a concerted multidiscipline approach is required to facilitate the reality and great potential benefits of cell-based tissue engineering applications.

First-Order Models for Configuration Analysis (2013)

Our world teems with networked devices. Their configuration exerts an ever-expanding influence on our daily lives. Yet correctly configuring systems, networks, and access-control policies is notoriously difficult, even for trained professionals. Automated static analysis techniques provide a way to both verify a configuration's correctness and explore its implications. One such approach is scenario-finding: showing concrete scenarios that illustrate potential (mis-)behavior. Scenarios even have a benefit to users without technical expertise, as concrete examples can both trigger and improve users' intuition about their system. This thesis describes a concerted research effort toward improving scenario-finding tools for configuration analysis. We developed Margrave, a scenario-finding tool with special features designed for security policies and configurations. Margrave is not tied to any one specific policy language; rather, it provides an intermediate input language as expressive as first-order logic. This flexibility allows Margrave to reason about many different types of policy. We show Margrave in action on Cisco IOS, a common language for configuring firewalls, demonstrating that scenario-finding with Margrave is useful for debugging and validating real-world configurations. This thesis also presents a theorem showing that, for a restricted subclass of first-order logic, if a sentence is satisfiable then there must exist a satisfying scenario no larger than a computable bound. For such sentences scenario-finding is complete: one can be certain that no scenarios are missed by the analysis, provided that one checks up to the computed bound. We demonstrate that many common configurations fall into this subclass and give algorithmic tests for both sentence membership and counting. We have implemented both in Margrave. Aluminum is a tool that eliminates superfluous information in scenarios and allows users' goals to guide which scenarios are displayed. We quantitatively show that our methods of scenario-reduction and exploration are effective and quite efficient in practice. Our work on Aluminum is making its way into other scenario-finding tools. Finally, we describe FlowLog, a language for network programming that we created with analysis in mind. We show that FlowLog can express many common network programs, yet demonstrate that automated analysis and bug-finding for FlowLog are both feasible as well as complete.
Saccade-Stepping Interactions Revise the Motor Plan for Obstacle Avoidance (2003)

The authors used a stimulus-response compatibility paradigm to assess the effect of changing the estimated time to obstacle contact. A limb-selection cue was presented in different phases of gait to young (n = 5) and to older (n = 4) adults while they were moving toward a foam obstacle in the walking path. A downward saccade was initiated after the cue; the saccade typically occurred during the stance phase of the target limb (the foot cued to lead the step over the obstacle). The mean saccade-step latency after the cue was on the order of -500 ms in both young and elderly participants. On reaching the obstacle, both groups generated an upward saccade approximately -300 ms before target footlift in both groups. Saccades following the limb-selection cue appeared to direct the gaze toward footfall targets just beyond the obstacle, whereas saccades generated just before obstacle footlift moved the gaze to the forward-looking direction. The elderly had significantly longer saccade-trailing-footlift latencies and prolonged gaze-fixation times than did the younger adults. Transient disruptions in optical flow appeared to be necessary for successful obstacle-avoidance behavior when there was an unexpected change in the estimated time to obstacle contact.
LIME: Low-Light Image Enhancement via Illumination Map Estimation (2016)

When one captures images in low-light conditions, the images often suffer from low visibility. Besides degrading the visual aesthetics of images, this poor quality may also significantly degenerate the performance of many computer vision and multimedia algorithms that are primarily designed for high-quality inputs. In this paper, we propose a simple yet effective low-light image enhancement (LIME) method. More concretely, the illumination of each pixel is first estimated individually by finding the maximum value in R, G, and B channels. Furthermore, we refine the initial illumination map by imposing a structure prior on it, as the final illumination map. Having the well-constructed illumination map, the enhancement can be achieved accordingly. Experiments on a number of challenging low-light images are present to reveal the efficacy of our LIME and show its superiority over several state-of-the-arts in terms of enhancement quality and efficiency.
La Portada del Perdón de la Iglesia Colegial de Daroca: Estado de la cuestión (1989)

Droplet microfluidics has emerged as a critical component of several high-throughput single-cell analysis techniques in biomedical research and diagnostics. Despite significant progress in the development of individual assays, multiparametric optical sensing of droplets and their encapsulated contents has been challenging. The current approaches, most commonly involving microscopy-based high-speed imaging of droplets, are technically complex and require expensive instrumentation, limiting their widespread adoption. To address these limitations, we developed the OptiDrop platform; this platform is a novel optofluidic setup that leverages the principles of flow cytometry. Our platform enables on-chip detection of the scatter and multiple fluorescence signals from the microfluidic droplets and their contents using optical fibers. The highly customizable on-chip optical fiber-based signal detection system enables simplified, miniaturized, low-cost, multiparametric sensing of optical signals with high sensitivity and single-cell resolution within each droplet. To demonstrate the ability of the OptiDrop platform, we conducted a differential expression analysis of the major histocompatibility complex (MHC) protein in response to IFN<i>γ</i> stimulation. Our results showed the platform's ability to sensitively detect cell surface biomarkers using fluorescently labeled antibodies. Thus, the OptiDrop platform combines the versatility of flow cytometry with the power of droplet microfluidics to provide wide-ranging, scalable optical sensing solutions for research and diagnostics.

Dislocation Over a Bounded Plane Area in an Infinite Solid (1957)

Abstract The Papkovitch functions are determined for an infinite isotropic elastic solid with an arbitrary displacement discontinuity over a bounded plane area. A solution, in closed form, is given for the case of a constant discontinuity in the displacement over a rectangular area.
Photoinhibition at room temperature in Dunaliella salina 1009 (2000)

Dunaliella salina 1009 possesses a greater tolerance to high irradiance and has a much high rate of recovery of photosynthesis after photoinhibition. Changes in photosynthesis rate and photochemical characteristics in response to high irradiance, followed by recovery at low irradiance, were determined in four groups of Dunaliella salina 1009. They were untreated algae, algas beated with either an inhibition of energy dissipation associated with the Xanthophyll cycle (DTT) or an inhibition of ecoded protein synthesis (CAP), as well as algae beated with a combination of CAP+ DTT. Treatment of algae with either CAP or DTT resulted in a more pronounced decrease in the rate of photosynthesis subsequent to the treatment at high PFD, but the depression of photochemical efficiency and photo efficiency of photosynthetic oxygen evolution was reversible, i.e., CAP- or DTT-sensitive process didn' t prevent the rapid recovery of photochemical system. However, subsequent to the same exposure, the highest level of depression and a low recovery was observed when these algae were treated with a combination of CAP+DTT. This means that CAP or DTT-sensitive process is not completely related in Dunaliella salina 1009. Meanwhile, in algae breated with CAP+DTT, DTT, further decrease in the PSll reduction state, as well as the slow decrease in Fm, (the slow increase in non-photochemical quenching), would be consistent with the development of an additional Xanthophyll cycleindependent process that dissipates excess energy in PSII. This apparently develops during high PFD and persists upon return to low PFD. It may cause the photochemical system to reversibly return to a high functional photosynthetic state.
Predictive voltage control of three-phase voltage source inverters to supply nonlinear and unbalanced loads (2015)

In this paper, model predictive control is applied to control a three-phase inverter. Model predictive control (MPC) is known for its simplicity and ease of use. The discussed inverter is generating pure sinusoidal voltages for sensitive applications such as uninterruptable power supply systems with low voltage total harmonic distortion (THD) demand. This method uses the model of the system to predict the behavior of the voltage on the next sampling interval for each possible switching state. A cost function is also used to decide which switching state to be applied based on minimizing the voltage deviations from the reference value and switching losses. Simulations have been done using PSCAD/MATLAB interfacing and results show the feasibility of MPC to control inverters feeding linear, nonlinear or unbalanced loads.

Excited State Properties of Oligophenyl and Oligothienyl Swivel Cruciforms (2008)

A comprehensive study has been undertaken of the electronic spectral and photophysical properties of two oligophenyl (BPH and BPHF) and one oligothienyl (BTF) swivel cruciforms involving measurements of absorption, fluorescence, and phosphorescence spectra, quantum yields of fluorescence (phiF), phosphorescence (phiPh) and triplet formation (phiT), lifetimes of fluorescence (tauF) and of the triplet state (tauT), and quantum yields of singlet oxygen production (phiDelta). From these, all radiative kF and radiationless rate constants, kIC and kISC, have been obtained in solution. The energies of the lowest lying singlet and triplet excited states were also determined at 293 K. Several of the above properties have also been obtained at low temperature and in the solid state (thin films). In general, for the phenyl oligophenyl (BPH) and for the oligothienyl (BTF) compounds, the radiationless decay channels (phiIC+phiISC) are the dominant pathway for the excited-state deactivation, whereas with the fluorene based oligophenyl BPHF the radiative route prevails. In contrast to the general rule found for related oligomers (and polymers) where radiative emission from T1 is absent, with the compounds studied, phosphorescence has been observed for all of the compounds, indicating that this type of functionalization can lead to emissive triplets. Time-resolved fluorescence decays with picosecond resolution revealed multiexponential (bi- and triexponential) decay laws compatible with the existence of more than one species or conformation in the excited state. These results are discussed on the basis of conformational flexibility in the excited state.
Vision-Based Projection-Handwriting Integration in Classroom (2006)

A projector based presentation and a whiteboard handwriting capture system, when monitored by a camera, could provide a better means to present a lecture in a classroom and later to deliver more effective e-lectures for off-campus students. When the PowerPoint© (PPT) slides are projected on the whiteboard where the instructor annotates, modifies, or expands the PPT presentation, geometrically registering high-resolution images from the two sources yields high quality digital presentations. Since the two sources do not share the same materials, one with printing notes and the other with handwriting notes, a digital camera is used as a bridge to align the two sources, as well as to record the whole lecture. We present a hybrid registration approach to align the PPT and handwriting images and then propose a coarse-to-fine content matching method to register handwriting contents captured by the video camera and the whiteboard capture system. We also show an integrated user-customized presentation system to provide students better lecturing context. Experimental results are presented to validate our approach, and future research directions are also discussed.
