Coupled quantum dots as quantum gates (1999)

We consider a quantum-gate mechanism based on electron spins in coupled semiconductor quantum dots. Such gates provide a general source of spin entanglement and can be used for quantum computers. We determine the exchange coupling $J$ in the effective Heisenberg model as a function of magnetic $(B)$ and electric fields, and of the interdot distance $a$ within the Heitler-London approximation of molecular physics. This result is refined by using $\mathrm{sp}$ hybridization, and by the Hund-Mulliken molecular-orbit approach, which leads to an extended Hubbard description for the two-dot system that shows a remarkable dependence on $B$ and $a$ due to the long-range Coulomb interaction. We find that the exchange $J$ changes sign at a finite field (leading to a pronounced jump in the magnetization) and then decays exponentially. The magnetization and the spin susceptibilities of the coupled dots are calculated. We show that the dephasing due to nuclear spins in GaAs can be strongly suppressed by dynamical nuclear-spin polarization and/or by magnetic fields.
Use of ontologies for bridging semantic gaps in distant communication (2008)

In this paper, we show how ontology can be utilized to support distant communication. Although augmented with audio and video functions, and screen sharing facilities, the users of real-time communication tools are facing difficulties due to their inability to provide appropriate meaning for keywords or conversation topics. Our system fills the semantic gap and supports the knowledge of keywords related to a specific topic. This paper presents an extended approach that uses different domain ontologies to carry out mapping by agents. Assisting a teacher by providing appropriate information to students as an intelligent tutoring system is one example application. This paper describes a sample scenario of computer usage operations in an English composition class that shows how the semantic gap between teachers and students can be filled using ontologies.

Volumetric Correspondence Networks for Optical Flow (2019)

Many classic tasks in vision -- such as the estimation of optical flow or stereo disparities -- can be cast as dense correspondence matching. Well-known techniques for doing so make use of a cost volume, typically a 4D tensor of match costs between all pixels in a 2D image and their potential matches in a 2D search window. State-of-the-art (SOTA) deep networks for flow/stereo make use of such volumetric representations as internal layers. However, such layers require significant amounts of memory and compute, making them cumbersome to use in practice. As a result, SOTA networks also employ various heuristics designed to limit volumetric processing, leading to limited accuracy and overfitting. Instead, we introduce several simple modifications that dramatically simplify the use of volumetric layers - (1) volumetric encoder-decoder architectures that efficiently capture large receptive fields, (2) multi-channel cost volumes that capture multi-dimensional notions of pixel similarities, and finally, (3) separable volumetric filtering that significantly reduces computation and parameters while preserving accuracy. Our innovations dramatically improve accuracy over SOTA on standard benchmarks while being significantly easier to work with - training converges in 10X fewer iterations, and most importantly, our networks generalize across correspondence tasks. On-the-fly adaptation of search windows allows us to repurpose optical flow networks for stereo (and vice versa), and can also be used to implement adaptive networks that increase search window sizes on-demand.
Machine Learning Paradigms for Next-Generation Wireless Networks (2016)

Next-generation wireless networks are expected to support extremely high data rates and radically new applications, which require a new wireless radio technology paradigm. The challenge is that of assisting the radio in intelligent adaptive learning and decision making, so that the diverse requirements of next-generation wireless networks can be satisfied. Machine learning is one of the most promising artificial intelligence tools, conceived to support smart radio terminals. Future smart 5G mobile terminals are expected to autonomously access the most meritorious spectral bands with the aid of sophisticated spectral efficiency learning and inference, in order to control the transmission power, while relying on energy efficiency learning/inference and simultaneously adjusting the transmission protocols with the aid of quality of service learning/inference. Hence we briefly review the rudimentary concepts of machine learning and propose their employment in the compelling applications of 5G networks, including cognitive radios, massive MIMOs, femto/small cells, heterogeneous networks, smart grid, energy harvesting, device-todevice communications, and so on. Our goal is to assist the readers in refining the motivation, problem formulation, and methodology of powerful machine learning algorithms in the context of future networks in order to tap into hitherto unexplored applications and services.
Characterization at different aspect ratios (radius/length) of a radio frequency inductively coupled plasma source (1995)

Ion densities, electron temperatures, plasma potentials, and absorbed powers are measured in a planar inductively coupled argon plasma source at different input powers, pressures, and aspect ratios (radius/length) and are compared to both a global (volume-averaged) model and a two-dimensional (2D) fluid model. Qualitatively, the trends between the models and experiment are similar. Radial ion density profiles at different aspect ratios and pressures are also measured. An ion density peak off-axis is measured at a high aspect ratio and predicted by the 2D fluid model.
Evaluation of the accuracy of three-dimensional reconstruction of edentulous model jaw relation based on dental articulator positioning (2013)

A dental articulator and three-dimensional (3D) scanner were utilized to reconstruct the spatial relationship between upper and lower edentulous jaw gypsum models made from five patients. The 7-axis Faro Edge contact measurement system was used to evaluate the vertical and horizontal distances between jaws. Paired t-test results of vertical distance (0.089±0.428 mm) and horizontal distance (-0.082±0.221 mm) between points on the jaws showed no significant differences (P>0.05). One-Way ANOVA of the same measurement data for the five models also showed no significant differences (P>0.05). With an error of less than 0.1 mm, these measurements met clinical requirements. In conclusion, 3D reconstruction of edentulous jaw gypsum models with accurate jaw relation was made possible by scanning the models in centric relation on a dental articulator.
Mice lacking 5‐HT<sub>7</sub> receptors show specific impairments in contextual learning (2004)

Using 5-HT(7) receptor knockout mice it has been shown that the 5-HT(7) receptor is the main mediator of serotonin-induced hypothermia but very little is known about the relevance of 5-HT(7) receptors in behaviour. We here report that lack of 5-HT(7) receptors leads to a specific learning deficit that is not due to general sensory or behavioural deficits. The knockout mice show impaired contextual fear conditioning but no significant deficits in motor and spatial learning or cued and operant conditioning. In addition, we demonstrate that 5-HT(7) receptor knockout mice display decreased long-term synaptic plasticity within the CA1 region of the hippocampus. The results indicate an important role for the 5-HT(7) receptor in contextual hippocampal-dependent learning and suggest a possible neuronal correlate for such a role is present within the CA1 region of the hippocampus.
<title>New dermatological biomedical microscopes for early clinical diagnostics</title> (1993)

With the current developments in optics, including laser optics, there should be more progress on the development of instrumentation for dermatological diagnostics, even clinical diagnostics. This report introduces new microscopy, much still under development, and research. A frank appeal for this program is made for multi-discipline help from optical physicists, biophysicists, biomedical engineers, even laser biomedical engineers, investigative dermatologists, and pathologists. If one is allowed to say, the most current advanced clinical diagnostic microscope is the polarizing microscope under the stimulus of Rox Anderson, Lynn Drake, Steven Jacques, and Peter Dorogi. The other microscopes for clinical dermatological research to be developed include the confocal scanning microscopy with the emphasis for living tissue, the ultrasonic biomedical microscope (UBM) for dermatology, and the holographic microscope, related to our studies on the biomedical aspects of optical phase conjugation. All these are introduced briefly for our studies and for definite pleas to help us.
Nonlinear distortion mitigation in visible light communications (2015)

Many physical devices used in VLC systems exhibit nonlinear effects, which can significantly degrade the overall system performance. For example, the LED is the major source of nonlinearity. The forward current is zero unless the forward voltage exceeds a turn-on value. The forward current is also limited with a maximum permissible value. In addition, the electrical-tooptical conversion is also nonlinear. In this article, we provide an overview of techniques related to modeling and distortion mitigation techniques of the nonlinearity in VLC systems. Appropriate models and robust nonlinearity mitigation techniques are crucial to support high-speed transmissions in practical VLC systems.
Heading-based sectional hierarchy identification for HTML documents (2007)

Most of the documents found on the Web are prepared in HTML format which was basically designed for presentation of data. As a result, some limitations are encountered when these documents are accessed automatically for a semantic interpretation of their content. One such inadequacy is in representing the sectional hierarchy (i.e. sections and subsections) of these documents and the headings in this hierarchy. Automatically obtaining this information is a difficult task due to the underlying format and the cluttered structure encountered in most of the Web pages. In this paper, we propose a novel approach to extract heading-based sectional hierarchies of HTML documents. This is the first part of the research, where we aim to use this information in automatic summaries to improve Web search experience of Internet users.

Neuroprotective mesenchymal stem cells are endowed with a potent antioxidant effect <i>in vivo</i> (2009)

Experimental autoimmune encephalomyelitis (EAE), an animal model for human multiple sclerosis, is characterized by demyelination, inflammation and neurodegeneration of CNS in which free radicals play a role. Recently, the efficacy of murine mesenchimal stem cells (MSCs) as treatment of EAE induced in mice by the encephalitogenic peptide MOG(35-55) was demonstrated. The present study analyzed some markers of oxidative stress, inflammation/degeneration and apoptosis such as metallothioneins (MTs), antioxidant enzymes (superoxide dismutase, catalase and glutathione-S-transferase), poly(ADP-ribose) polymerase-1 and p53 during EAE progression and following MSC treatment. Expression of the three brain MT isoforms increased significantly in EAE mice compared with healthy controls, but while expression of MT-1 and MT-3 increased along EAE course, MT-2 was up-regulated at the onset, but returned to levels similar to those of controls in chronic phase. The changes in the transcription and activity of the antioxidant enzymes and in expression of poly(ADP-ribose) polymerase-1 and p53 showed the same kinetics observed for MT-1 and MT-3 during EAE. Interestingly, i.v. administration of MSCs reduced the EAE-induced increases in levels/activities of all these proteins. These results support an antioxidant and neuroprotective activity for MSCs that was also confirmed in vitro on neuroblastoma cells exposed to an oxidative insult.
Three-dimensional trace analysis: combination of gas chromatography, supersonic beam UV spectroscopy and time-of-flight mass spectrometry (1995)

We present a three-dimensional method for trace analysis by combining three different analytical techniques: gas chromatography, well-resolved gas-phase UV spectroscopy of cold molecules and time-of-flight mass spectrometry with a laser ionization source. The interface is a newly developed pulsed valve, which acts as a GC-MS coupling as well as a valve for the pulsed supersonic beam. We prove that the selectivity of both the gas chromatography and the UV spectroscopy is preserved. The preliminary sensitivity is better than 500 fg for toluene, an improvement by two orders of magnitude seems realizable. Some further spectra of molecular isomers, such as PAHs of mass 252, chlorotoluenes or chloroanthracenes are shown as examples of how UV spectroscopy of even larger molecules allows isomer selective multiphoton ionization. The selectivity of this step is large enough so that time-consuming clean-up procedures of the sample are not necessary and medium resolution, but fast gas chromatography can be used.

Saponins from the Aerial Parts of Aralia continentalis (1998)

Seven triterpenoid saponins such as oleanolic acid 28-O-β-D-glucopyranosyl ester, hederagenin 28-O-β-D-glucopyranosyl ester, chikusetsusaponin IVa, udosaponin A, salsoloside C, udosaponins F and C were isolated from the aerial parts of Aralia continentalis, among which two 28-O-β-D-glucopyranosyl esters of oleanolic acid and hederagenin are isolated for the first time from this plant. These results suggested that the chemical components of Korean Dokwhal are practically identical to those of Japanese Udo supporting the chemotaxonomical point of view.
SKI2162, an inhibitor of the TGF-β type I receptor (ALK5), inhibits radiation-induced fibrosis in mice (2015)

Here we demonstrated that SKI2162, a small-molecule inhibitor of the TGF-β type I receptor (ALK5), prevented radiation-induced fibrosis (RIF) in mice. SKI2162 inhibited phosphorylation of Smad and induction of RIF-related genes in vitro. In RIF a mouse model, SKI2162 reduced late skin reactions and leg-contracture without jeopardizing the acute skin reaction. Irradiation of mouse tissue increased COL1A2 mRNA levels, and topical administration of SKI2162 significantly inhibited this effect. Thus, these findings support that SKI2162 has potential value as novel RIF-protective agent, and could be candidate for clinical trials.

GPU Domain Specialization via Composable On-Package Architecture (2021)

As GPUs scale their low-precision matrix math throughput to boost deep learning (DL) performance, they upset the balance between math throughput and memory system capabilities. We demonstrate that a converged GPU design trying to address diverging architectural requirements between FP32 (or larger)-based HPC and FP16 (or smaller)-based DL workloads results in sub-optimal configurations for either of the application domains. We argue that a C omposable O n- PA ckage GPU (COPA-GPU) architecture to provide domain-specialized GPU products is the most practical solution to these diverging requirements. A COPA-GPU leverages multi-chip-module disaggregation to support maximal design reuse, along with memory system specialization per application domain. We show how a COPA-GPU enables DL-specialized products by modular augmentation of the baseline GPU architecture with up to 4× higher off-die bandwidth, 32× larger on-package cache, and 2.3× higher DRAM bandwidth and capacity, while conveniently supporting scaled-down HPC-oriented designs. This work explores the microarchitectural design necessary to enable composable GPUs and evaluates the benefits composability can provide to HPC, DL training, and DL inference. We show that when compared to a converged GPU design, a DL-optimized COPA-GPU featuring a combination of 16× larger cache capacity and 1.6× higher DRAM bandwidth scales per-GPU training and inference performance by 31% and 35%, respectively, and reduces the number of GPU instances by 50% in scale-out training scenarios.

Femtosecond off-axis digital holography for monitoring dynamic surface deformation (2010)

We present a femtosecond off-axis digital holography for investigating the dynamic reversible surface change of a metal film induced by femtosecond laser pulses with fluences near the ablation threshold. A reflection Michelson interferometer (RMI) and a transmission Mach–Zehnder interferometer (TMZI) are integrated in the same setup for recording digital holograms. The RMI is used to measure the laser-induced surface deformation of the metal film, while the TMZI is used to analyze the refraction index change of the metal film induced by the femtosecond laser pulses. Experimental results show that both surface modification and refraction index change of chromium metal film can be observed when femtosecond laser pulses are below and above the ablation threshold. Based on the experimental results, the physical processes of the metal induced by femtosecond laser pulses are given qualitatively.
High CO<sub>2</sub>‐Capture Ability of a Porous Organic Polymer Bifunctionalized with Carboxy and Triazole Groups (2013)

A new porous organic polymer, SNU-C1, incorporating two different CO2 -attracting groups, namely, carboxy and triazole groups, has been synthesized. By activating SNU-C1 with two different methods, vacuum drying and supercritical-CO2 treatment, the guest-free phases, SNU-C1-va and SNU-C1-sca, respectively, were obtained. Brunauer-Emmett-Teller (BET) surface areas of SNU-C1-va and SNU-C1-sca are 595 and 830 m(2) g(-1), respectively, as estimated by the N2-adsorption isotherms at 77 K. At 298 K and 1 atm, SNU-C1-va and SNU-C1-sca show high CO2 uptakes, 2.31 mmol g(-1) and 3.14 mmol g(-1), respectively, the high level being due to the presence of abundant polar groups (carboxy and triazole) exposed on the pore surfaces. Five separation parameters for flue gas and landfill gas in vacuum-swing adsorption were calculated from single-component gas-sorption isotherms by using the ideal adsorbed solution theory (IAST). The data reveal excellent CO2-separation abilities of SNU-C1-va and SNU-C1-sca, namely high CO2-uptake capacity, high selectivity, and high regenerability. The gas-cycling experiments for the materials and the water-treated samples, experiments that involved treating the samples with a CO2-N2 gas mixture (15:85, v/v) followed by a pure N2 purge, further verified the high regenerability and water stability. The results suggest that these materials have great potential applications in CO2 separation.
